Description

Technical Field

[0001] This utility model relates to the field of railway repair technology, and in particular to a P60 movable-point turnout composite eccentric sleeve extractor. Background Technology

[0002] With the rapid development of railways and the deepening of railway system reform, the requirements for railway line quality are becoming increasingly higher, which also presents us with greater challenges. We must ensure that the lines are in good condition while improving operational efficiency, so technological innovation is particularly important.

[0003] Currently, all mainline turnouts under the jurisdiction of major railway groups are P60-1 / 12 movable-point turnouts. Due to the impact of train bodies, the composite eccentric sleeve of the switch rail is deformed by compression, and the frame dimensions at the switch rail are prone to change, resulting in the track gauge and track gauge gradient not meeting the requirements. During the operation, when adjusting different models of composite eccentric sleeves to rectify the switch rail frame and track gauge, the composite eccentric sleeves are difficult to remove, affecting the efficiency of track maintenance windows.

[0004] In daily operations, the work area lacks specialized tools when disassembling the composite eccentric sleeve. It is removed using only simple tools such as large and small pry bars. Due to uneven force during operation, the upper edge cap of the composite eccentric sleeve is easily detached from the lower inner liner, causing damage to the composite eccentric sleeve, increasing the difficulty of removal, wasting time and effort, and wasting materials. Utility Model Content

[0005] The purpose of this invention is to provide a P60 movable turnout composite eccentric sleeve extractor to solve the problems mentioned in the background art.

[0006] The P60 movable turnout composite eccentric sleeve remover includes a fixed frame and a push rod: two fixed frames are provided, and the upper end of the two fixed frames is provided with a connecting mechanism. The internal thread of the connecting mechanism is provided with a push rod. The lower side of the fixed frame is provided with a positioning mechanism for limiting the eccentric sleeve.

[0007] Preferably, the connecting mechanism includes a limiting strip and a limiting block, the limiting strip being embedded inside the fixed frame, and the limiting blocks being equidistantly arranged at the upper end of the limiting strip.

[0008] When the device is in use, the upper end of the fixed frame is fixed by embedding the limit strip inside the fixed frame. The limit block can increase the stability of the limit strip during use and prevent the limit strip from breaking due to excessive force.

[0009] Preferably, the limiting block is V-shaped, and the inside of the fixing frame is provided with a corresponding slot for the limiting block to be embedded.

[0010] By embedding the limiting block into the slot, the contact area between the limiting strip and the fixing frame can be increased, thereby reducing the local pressure on the limiting strip and further preventing the limiting strip from breaking. At the same time, it can also prevent the limiting strip from shifting under force, thus improving the stability of the equipment during use.

[0011] Preferably, the positioning mechanism includes a bracket and a fixing hole, the bracket is symmetrically arranged on both sides of the fixing frame, and the fixing hole is provided inside the bracket.

[0012] When the device is in use, the bracket and the fixed frame are fixed, so the material can be moved upward by the bracket, thereby increasing the stability of the eccentric sleeve when it is taken out; and the number and position of the fixing holes can be adjusted according to the actual situation, so as to facilitate the use of the equipment.

[0013] Preferably, a base post is embedded inside the fixing hole.

[0014] Once the bottom column is embedded in the fixing hole, it can limit the eccentric sleeve. Thus, when the equipment is in use, the rotating push rod drives the equipment and the eccentric sleeve to move simultaneously. The bottom column limits the eccentric sleeve, thereby pushing it out and improving the stability of the equipment during use.

[0015] Preferably, one end of the base post has a larger diameter than the other end, and a positioning plate is rotatably provided on the side of the end with a smaller diameter. One end of the positioning plate is connected to a torsion spring, and the other end of the torsion spring is connected to the base post.

[0016] When the device is in use, the base column is inserted into the fixing hole. The bracket guides the positioning plate, causing the positioning plate to tilt and retract into the fixing groove inside the bracket after the bracket and the positioning plate come into contact. This allows the base column to be installed smoothly. Afterward, the torsion spring drives the positioning plate to return to its original position. Because the fixing groove limits the positioning plate, the rotation angle of the positioning plate is within the range of 0-90°. This limiting effect of the positioning plate prevents the base column from slipping out.

[0017] The beneficial effects of this utility model are:

[0018] 1. When the device is in use, the bottom column is used to limit the eccentric sleeve. By embedding the bottom column into the fixing holes at different positions, materials of different sizes can be limited. Then, the top rod is used to drive the eccentric sleeve to move and separate.

[0019] 2. When the eccentric sleeve is ejected, the positioning plate will act as a limiter when the bottom column is tilted due to the force, thereby preventing the bottom column from slipping. The limit block will limit the limit strip, thereby preventing the limit strip from being misaligned. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] In practical implementation: such as Figure 1-3 As shown, the P60 movable turnout composite eccentric sleeve remover includes a fixed frame 1 and a push rod 4. There are two fixed frames 1, and the upper ends of the two fixed frames 1 are provided with a connecting mechanism. The internal threads of the connecting mechanism are provided with the push rod 4. The lower side of the fixed frame 1 is provided with a positioning mechanism for limiting the eccentric sleeve.

[0027] The connecting mechanism includes a limiting strip 2 and a limiting block 3. The limiting strip 2 is embedded inside the fixed frame 1, and the limiting block 3 is equidistantly arranged at the upper end of the limiting strip 2.

[0028] When the device is in use, the upper end of the fixed frame 1 is fixed by embedding the limiting strip 2 inside the fixed frame 1, while the limiting block 3 can increase the stability of the limiting strip 2 during use and prevent the limiting strip 2 from breaking due to excessive force.

[0029] The limiting block 3 is V-shaped, and the inside of the fixing frame 1 is provided with a corresponding slot for the limiting block 3 to be inserted.

[0030] By embedding the limiting block 3 into the slot, the contact area between the limiting strip 2 and the fixing frame 1 can be increased, thereby reducing the local pressure on the limiting strip 2 and further preventing the limiting strip 2 from breaking. At the same time, it can also prevent the limiting strip 2 from shifting under force, thereby improving the stability of the equipment during use.

[0031] The positioning mechanism includes a bracket 5 and a fixing hole 6. The bracket 5 is symmetrically arranged on both sides of the fixing frame 1, and the fixing hole 6 is provided inside the bracket 5.

[0032] When the device is in use, the bracket 5 is fixed to the fixed frame 1, so the material can be moved upward through the bracket 5, thereby increasing the stability of the eccentric sleeve when it is taken out; and the number and position of the fixing holes 6 can be adjusted according to the actual situation, so as to facilitate the use of the equipment.

[0033] The base post 7 is embedded inside the fixing hole 6.

[0034] When the bottom column 7 is embedded into the fixing hole 6, the bottom column 7 can limit the eccentric sleeve. Thus, when the equipment is in use, the rotating top rod 4 drives the equipment and the eccentric sleeve to move simultaneously. The bottom column 7 limits the eccentric sleeve, thereby pushing the eccentric sleeve out and improving the stability of the equipment during use.

[0035] One end of the base column 7 has a larger diameter than the other end. The side of the end of the base column 7 with a smaller diameter is provided with a positioning plate 8. One end of the positioning plate 8 is connected to a torsion spring 9, and the other end of the torsion spring 9 is connected to the base column 7.

[0036] When the device is in use, when the base column 7 is inserted into the fixing hole 6, the bracket 5 guides the positioning plate 8, so that after the bracket 5 and the positioning plate 8 come into contact, the positioning plate 8 will tilt and retract into the fixing groove inside the bracket 5, thus successfully completing the installation of the base column 7. Afterwards, the torsion spring 9 drives the positioning plate 8 to return to its original position. Since the fixing groove limits the positioning plate 8, the rotation angle range of the positioning plate 8 is 0-90°, thus preventing the base column 7 from being misaligned and slipping out through the limiting of the positioning plate 8.
