(1) The role of fasteners on construction sites
In construction projects, especially house construction, we can see dense construction scaffolding at any time. Construction workers use these scaffoldings to build high-rise buildings. , Scaffolding is a necessary auxiliary tool for various construction projects. No project can be erected without scaffolding. What connects various types of steel pipes into a stable and solid whole? Fasteners play a key role. Fasteners connect steel pipes through bolts and become the cornerstone of supporting construction projects.
(2) Reasons for development
In the construction equipment rental industry, the fastener rental business is a pillar project of construction rental companies because it is one of the essential construction tools in construction. It mainly For connecting and fixing scaffolding. In order to save capital investment, builders adopt the form of leasing, which can save many unnecessary links (purchasing, saving, cleaning, maintenance, repair, replacement). Builders can rent fasteners according to their own needs. Builders can The above tasks are transferred to the leasing company. The builder uses the completed fasteners. Due to poor management and storage, the returned fasteners to the leasing company must be renovated, cleaned, maintained and oiled before they can be used next time. Otherwise, the fasteners returned to the leasing company must be renovated, cleaned, maintained and oiled. The construction quality requirements cannot be met. The quality of fastener repairs directly affects construction safety and business, and also directly affects the market reputation of leasing companies and the economic benefits of construction projects.
The traditional cleaning method is due to the builder’s If the management is not good, the construction projects are all open-air operations, and wind and rain corrode the fasteners very seriously. There is also corrosion of the concrete at the construction site. You must first add lubricating oil and soak it for several hours, and then use a wrench to slowly remove it manually. Loosening. It is difficult to manually use a wrench to loosen fastener bolts. The fastener must be fixed first and then loosened. Therefore, manual operation is time-consuming, laborious, and inefficient. The quality of cleaning loosened parts is poor, and the bolts are easily damaged. The consumption of wrenches is very large, which also invisibly increases the capital investment of leasing companies.
Based on the actual production of our unit, our factory carries out technological innovation with the starting point of improving production efficiency, reducing labor intensity of employees, and improving economic benefits. After understanding the activity, dozens of rental stations (companies) in Kaifeng all perform this work manually. How can we use machinery to replace the original manual operation? Our bureau selects from various departments those who have excellent technology, strong business capabilities, and Technicians with a strong sense of responsibility and strong research spirit set up a scientific research team to conduct research in various leasing industries and construction sites. Based on the wind cannon machine for repairing vehicles, they used their wisdom and decided to develop a fastener bolt loosening machine. Passed After half a year of repeated experiments in use, we gradually improved and perfected, and successfully developed a fastener bolt loosening machine.

(3) Machine tool structural frame, three-phase asynchronous motor, long shaft, bearing seat, and handle.
The first section of the frame is welded with triangle iron, with a length of centimeters, a width of centimeters, and a height of centimeters.
Section 2 Fastener bolt loosening machine is powered by a three-phase asynchronous motor with rated power, rated voltage, rated current, speed/frequency.
The long axis of the third section is a shaft about one centimeter long and one centimeter in diameter. One end of the long axis is connected to the secondary driving wheel, and the other end is welded to a sleeve.
In the fourth section, two bearing seats, one driving wheel and one secondary driving wheel are driven by a triangle belt to drive the long axis to rotate.
Section 5: Install a reverse power switch on the handrail frame. One person can rotate the switch clockwise or counterclockwise with one hand and grasp the handle to loosen the bolt. The operator can operate freely.
(4) Working principle: Voltage is used as the driving force, and it is driven by a three-phase asynchronous motor through a belt, thereby driving the concave nut embedded in the long shaft to rotate. Use a special handle to fasten the fasteners, use the handle to insert the nut into the concave nut, and turn on the power to make the long axis rotate. The power switch is divided into forward rotation and reverse rotation. During operation, first forward rotation and then reverse rotation can complete the entire process of loosening the fastener.
Determination of machine power
The formula is the motor efficiency.
Under the speed intensity required by the design, repeat the above calculation to compare the motor power required for bolt loosening forces of different strengths. Obviously, from the perspective of energy consumption when converting electrical energy into kinetic energy, the one with smaller power is better. Use this principle to determine the size of the main power motor. After repeated testing and demonstration, a three-phase asynchronous motor was adopted.
Determination of the driving wheel and the driven wheel
The conversion of electrical energy into mechanical energy is completed through the driving wheel and the driven wheel. Determining the diameter of the driving wheel and the driven wheel is the key to the machinery. The relationship between the two diameters is determined by the rotation speed.

Determination of the distance between the handle and the switch
The straight-line distance between the handle and the switch is determined by first considering the person's adaptation range and the comfort level of the two arms. Through a large number of experiments and consulting relevant information, the optimal distance between the left arm and the right arm to achieve operation is body length.

(where is the distance from the handle to the switch.
Yes The above relationship gives the straight-line distance between the switch and the handle as space. Through experiments, the length of the handle was finally determined to be.
Manufacturing process and improvement measures
In the early stage of development, an asynchronous motor was used as the power of the equipment. Due to its heavy weight, it was inconvenient to move. On the other hand, it consumed electricity. Large. After experimental comparison, it was finally replaced with a three-phase asynchronous motor, which overcomes the above shortcomings and is more flexible and convenient to use.
