Description

Technical field:

[0001] The utility model relates to the technical field of railway line maintenance and repair, in particular to a bonded plywood dismantling device. Background technology:

[0002] Disassembly of the bonded plywood in bonded insulation joints has always been a crucial task during railway line maintenance. Existing disassembly techniques primarily rely on traditional physical methods, including heating with an open flame and prying with hammers and crowbars. Heating with an open flame vulcanizes the plywood colloid at high temperatures, thereby achieving disassembly. Hammering with a crowbar, on the other hand, directly destroys the plywood using physical force.

[0003] The existing technology has the following shortcomings:

[0004] 1. Low safety: ① Using open flames for heating presents significant safety risks. High-temperature operation can easily cause fires or explosions, posing a threat to the lives of workers. ② Using hammers and crowbars for prying can easily cause damage to the rails, affecting the normal use and safety of line equipment.

[0005] 2. Inefficiency: ① Open flame heating requires a long time to vulcanize the colloid of the bonded plywood, making the disassembly process time-consuming and difficult to control the temperature, which affects the disassembly effect. ② The hammering and crowbar prying method requires manual operation. The disassembly process depends on the operator's experience and technical level, resulting in low efficiency and high labor intensity.

[0006] 3. Complex Operation: ① Traditional disassembly methods require specialized equipment and tools, and the operation process is tedious and complex, requiring high operator skills. ② Disassembly procedures require strict control of operating procedures and parameter settings to avoid unnecessary damage to the rails and the surrounding environment.

[0007] 4. Environmental pollution: ① Using open flame heating will produce harmful gases and smoke, causing environmental pollution. ② The residual colloid after disassembly is difficult to clean, which brings many inconveniences to subsequent work and also causes environmental pollution.

[0008] 5. Unsatisfactory disassembly results: ① Traditional disassembly methods often fail to completely disassemble the adhesive plywood, resulting in some adhesive residue remaining on the rails, affecting the normal maintenance of line equipment. ② Disassembly procedures can easily damage the rails, affecting their smoothness and stability.

[0009] In summary, the existing technology has many shortcomings and deficiencies in the disassembly of the bonded plywood of the bonded insulating joints of railway lines, and a safer, more efficient and more environmentally friendly disassembly technology is needed to solve these problems. Summary of the invention:

[0010] In order to realize the cold disassembly of the bonded plywood, avoid the use of open flame heating, hammering, crowbar prying and other means, and improve work efficiency and safety, the utility model provides a bonded plywood disassembler for removing the bonded plywood on two sections of steel rails connected by the bonded plywood, which consists of a base plate and a rail buckle groove arranged on the lower side of the base plate, a fixing ear and a top rail groove arranged on the base plate, the rail buckle groove is arranged upside down on the rail, and is used to fix the left section of the two rails, the fixing ear is used to form a fulcrum on the bonded plywood, and the top rail groove is used to place a hydraulic square sleeper to push the right section of the rail, so that the joint of the left section of the rail and the right section of the rail is dislocated, thereby causing the bonded plywood at the joint to crack and detach.

[0011] The rail-locking groove is located on the left bottom surface of the front end of the base plate and can be clamped on the top surface of the left section of the rail.

[0012] There are two fixing ears, located on the left and right bottom surfaces of the base plate, and both are located behind the rail-locking groove. During use, the fixing ears are attached to the bonding plate between the two rail sections as a fulcrum. The top rail groove is a hollow square slot located on the right side of the base plate and is used to accommodate the hydraulic square sleeper. The fixing ears are provided with bolt holes. During use, joint bolts are installed in these bolt holes and tightened against the bonding plate between the two rail sections to form a fulcrum. The base plate is also provided with handles on the front and back sides for lifting the disassembler.

[0013] Compared with traditional disassembly methods, this utility model has the following advantages:

[0014] High safety: The present invention does not require the use of open flame heating and electric welding, eliminating the risk of fire and explosion; at the same time, it avoids the external damage to the rails that may be caused by traditional methods such as hammering and crowbar prying, greatly improving the safety of the disassembly process.

[0015] High efficiency: The hydraulic square sleeper provides thrust, which enables precise control of the rails. The disassembly process is fast and efficient, greatly saving manpower and time costs.

[0016] Environmental protection and energy saving: No open flame is required during the disassembly process, which reduces the emission of harmful gases and smoke; at the same time, the colloid remaining after disassembly is easy to clean, reducing pollution to the environment.

[0017] Easy to operate: The present invention has a simple structure and is easy to operate. It only requires the disassembly device to be installed on the rail and the hydraulic square sleeper to be placed in the pushing groove to carry out the disassembly work without the need for complicated operating procedures and parameter settings.

[0018] Strong applicability: The present invention is suitable for dismantling cemented plywood at insulation joints of railway lines of various rail types and has wide applicability. Description of the drawings:

[0023] like Figure 1 As shown, the utility model provides a bonding plywood disassembler for removing the bonding plywood 1 on two sections of rails 2 connected by the bonding plywood 1, and is composed of a base plate 3 and a rail buckle groove 4, a fixing ear 5 and a top rail groove 6 arranged on the base plate 3 on the lower side of the base plate 3. The rail buckle groove 4 is arranged upside down on the rail 2 and is used to fix the left section rail 2-1 of the two sections of the rail 2. The fixing ear 5 is used to form a fulcrum on the bonding plywood 1, and the top rail groove 6 is used to place a hydraulic square sleeper 7 to push the right section rail 2-2, so that the joint between the left section rail 2-1 and the right section rail 2-2 is dislocated, thereby causing the bonding plywood 1 at the joint to crack and detach.

[0024] The rail-holding groove 4 is located on the left bottom surface of the front end of the base plate 3 and can be clamped on the top surface of the left section of the rail 2-1. There are two fixing ears 5, which are respectively located on the left and right bottom surfaces of the base plate 3 and are both located on the rear side of the rail-holding groove 4. When in use, the fixing ears 5 are attached to the bonding plywood 1 between the two sections of the rail 2 as a fulcrum. The top rail groove 6 is a hollow square slot and is provided on the right side of the base plate 3 for placing the hydraulic square sleeper 7. A bolt hole 8 is provided on the fixing ear 5. When in use, a joint bolt 9 is installed in the bolt hole 8, and the joint bolt 9 is tightened on the bonding plywood 1 between the two sections of the rail 2 to form a fulcrum. Handles 10 are also provided on the front and back sides of the base plate 3 for lifting the disassembler.

[0025] Example: Operation process:

[0026] In actual operation, first, the disassembler needs to be installed on the bonded joint that needs to be disassembled. The rail groove 4 is buckled on the left-end rail 2-1, and the fixing ear 5 is inserted into the corresponding bolt hole 8 to insert the joint bolt 9, and ensure that it is firmly fixed. Then, the hydraulic square sleeper 7 is placed in the pushing groove 6, and the pushing cylinder of the hydraulic square sleeper 7 is aligned with the head of the right-end rail 2-2. Next, start the hydraulic square sleeper 7 to push, and push the right-end rail 2-2 through the hydraulic square sleeper 7 to cause the joint to be misaligned. When the joint is misaligned, the bonding splint 1 will naturally crack and detach. Finally, clean up the colloid remaining after disassembly to complete the disassembly work.
