- Hydraulic rail gap adjuster
As the earliest manufacturer of railway maintenance equipment in Liaoning, the products are constantly updated and services are constantly improved under the trend of railway science and technology development. As a new type of rail adjustment equipment, the rail gap adjuster is made of forged alloy steel as a whole. It is a nylon insulated wheel and a manual imported hydraulic pump. The overall cost performance is very high. It is divided into one-way, two-way, ton and ton. The overall cast steel hydraulic cylinder improves the performance several times. It occupies a leading position in rail adjustment equipment. It is mainly divided into The following models are available:
-Hydraulic rail gap adjuster
-Hydraulic rail gap adjuster is suitable for rail gap adjustment operations of various rail types. It adopts four-pin double insurance safety measures to enhance safety performance. , compact structure, beautiful appearance, light weight, easy maintenance, reasonable clamping tooth shape and sufficient static strength.

Basic structure and Working principle
1. Basic structure: Mainly composed of running wheel, inclined iron, clamp body, safety pin, return spring, safety lowering device, oil tank, oil cylinder, oil pump, overflow valve, oil return valve, tie rod, etc. .
The main structure is as shown in the figure: front clamp body, piston rod, 3 oil cylinders, oil return valve (the other side is the backup oil return valve), middle clamp body, tie rod, inclined iron (block), rear clamp body, large Safety pin, lever, oil pump rocker, oil tank, 3 return springs, small safety pin (piece).

Working principle:
When increasing the rail gap (i.e. pushing the rail): use the front clamp concrete and the middle clamp concrete, the rear clamp concrete does not participate in the work. Hydraulic oil is pressed into the double cylinders through four plunger pumps, and the pistons extend outward. After the inclined irons in the front and middle clamping bodies clamp the two rails, they push the rails to increase the gap between the two rails. To achieve the purpose of adjusting the rail seam.
When narrowing the rail gap (i.e. pulling the rail): use the middle clamp concrete and the rear clamp concrete, the front clamp concrete does not participate in the work. The hydraulic oil is pressed into the double cylinder through four plunger pumps. The piston extends outward. After the inclined iron in the middle clamp body and the rear clamp body clamps the two rails through the pull rod, the rail is pulled to create a gap between the two rails. shrink to achieve the purpose of adjusting the rail gap.

Correct use and maintenance play an important role in ensuring the normal operation of the machine and extending its service life. The operator should read this manual carefully to understand the structure and function of each part.
(1) Inspection before use
Whether the oil level in the tank reaches /3 of the tank height. Use engine oil in summer and engine oil in winter. Filter when refueling.
Whether the control part is flexible and reliable.
Whether the oil return valve opens and closes normally, and whether all hydraulic parts work normally.
Check whether the fastening parts of each connection are loose and whether there is oil leakage.
(ii) Operation steps
Place the machine tool at the joint of the two rails being adjusted. When the rail needs to be pushed, the rail seam should be located between the front clamp body and the middle clamp body. When the rail needs to be pulled, Make the rail seam located between the middle clamp body and the rear clamp body.
, Move the control lever on the corresponding clamp body downward to make the clamp body fall on the rail.
. Tighten the oil return valve clockwise, and use the joystick to shake the rocker of the oil pump to input the hydraulic oil into the working cylinder 3. When the piston is extended, the inclined iron can clamp the rail. Continue to shake the joystick. Achieve the purpose of adjusting rail seams.
. Attention! When pushing the rail, you should gently pull the lever handle on the back clamp body upward so that the inclined iron and the rail do not touch the pull rail. The rails do not pull.
After each adjustment of the rail seam, you should first unscrew the oil return valve in the counterclockwise direction, then move the lever upward to loosen the inclined iron, so that the piston of the working cylinder is reset under the action of the tension spring, which completes a working cycle. . (This machine is equipped with two oil return valves. When one of them fails, open the other oil return valve to reset the oil cylinder, which improves the safety performance of the machine.)
After completing the operation, press upward Move the lever on each clamp body, use the pawl to drop the running wheel on the rail surface, and push it to the next rail seam or the lower track of the complete machine.
. There is a relief valve in the fuel tank, and its pressure has been adjusted before leaving the factory. When the load is too large, the relief valve unloads to ensure the safety of the machine.
If the workload of pushing the rails is large, it is recommended to remove the rear clamp body and tie rods to reduce the weight of the entire machine.
