Description

Technical Field

[0001] The present application relates to the field of hydraulic cylinders, and in particular to a hydraulic cylinder assembly of a hydraulically bonded insulating splint disassembly device. Background Art

[0002] In the field of rail transit, it is necessary to install insulating splints on both sides of the rail waist. The insulating splints are fixed to the rail waist by gluing. When the insulating splints are damaged or have been in service for a long time, the users need to destroy the adhesive layer and remove the insulating splints, and then reinstall new insulating splints on the rails.

[0003] The relevant insulating splint removal device includes a frame, a cylinder and a tool. The cylinder body of the cylinder is fixed on the frame, and the piston rod of the cylinder is connected to the tool. The user sets the frame on the rail so that the cylinder can be horizontally set at the waist of the rail. The piston rod is extended and retracted to drive the tool to move back and forth horizontally, so that the tool can be inserted between the rail and the insulating splint and destroy the adhesive layer, thereby achieving the effect of removing the insulating splint.

[0004] The above-mentioned related technical solutions have the following defects: the reciprocating movement of the piston rod in the oil cylinder is completed by injecting oil into the oil cylinder through an oil pump, and the movement speed of the piston rod is slow. When multiple insulating splints need to be removed, the removal efficiency is low. Utility Model Content

[0005] In order to increase the speed at which the oil cylinder drives the tool to move, the present application provides a hydraulic oil cylinder assembly for a hydraulically bonded insulating splint disassembly device.

[0006] The hydraulic cylinder assembly of the hydraulically bonded insulating splint disassembly device provided in the present application adopts the following technical solution:

[0007] A hydraulic cylinder assembly of a hydraulically bonded insulating splint disassembly device comprises a cylinder barrel, a piston rod and a spring. The cylinder barrel is a cylindrical structure, a blind hole is opened at one end of the cylinder barrel, the piston rod is inserted into the blind hole of the cylinder barrel and is slidably connected to the cylinder barrel, and the spring is arranged in the cylinder barrel, one end of the spring is connected to the cylinder barrel, and the other end is connected to the piston rod.

[0008] By adopting the above technical solution, the piston rod is connected by sliding in the oil cylinder barrel, so that the hydraulic oil can push the piston rod to make the piston rod move back and forth in the oil cylinder barrel, and by arranging a spring in the oil cylinder barrel, when the piston rod is extended in the oil cylinder barrel, the piston rod drives the tool to insert into the insulating splint and the rail, and the feed speed is slow, thereby reducing the probability of the tool breaking when destroying the adhesive layer. At this time, the spring stretches and accumulates elastic potential energy. When the insulating splint is removed from the rail, the user controls the piston rod to slide into the oil cylinder barrel. At this time, the spring can pull the piston rod, so that the piston rod can drive the tool to retract quickly, thereby increasing the speed of the tool retraction, making it convenient for the user to retract the tool and continue the removal of other insulating splints, thereby improving work efficiency.

[0009] Optionally, an oil chamber is opened at the end of the piston rod, and the spring is arranged in the oil chamber.

[0010] By adopting the above technical solution, an oil chamber is opened at the end of the piston rod, so that the spring can be inserted into the oil chamber and connected to the piston rod, so that a spring with a longer length can be installed in the cylinder barrel, further improving the speed at which the piston rod is retracted into the cylinder barrel, so that the tool can be quickly retracted after removing the insulating splint.

[0011] Optionally, hanging rings are fixed at both ends of the spring, and the ends of the spring are detachably connected to hooks, the ends of the hooks are connected to bolts, and the bolts are threadedly connected in the cylinder barrel or the piston rod.

[0012] By adopting the above technical solution, a hanging ring is provided at the end of the spring, so that the end of the spring can be fixed in the cylinder or the piston rod through the hook, thereby facilitating users to replace aged springs.

[0013] Optionally, the spring is coaxially arranged with the oil cylinder.

[0014] By adopting the above technical solution, the spring and the cylinder barrel are coaxially arranged, so that the tension of the spring on the cylinder barrel and the piston rod can be evenly distributed, thereby reducing the probability of the piston rod being skewed or deformed in the cylinder barrel, and keeping the coaxiality of the piston rod and the cylinder barrel in a higher range.

[0015] Optionally, the oil cylinder barrel is provided with one oil hole, which passes through the oil cylinder barrel and is connected to a blind hole of the oil cylinder barrel.

[0016] By adopting the above technical solution, an oil hole is opened on the oil cylinder barrel, so that the oil pump can inject hydraulic oil into the oil chamber through the oil hole and push the piston rod, so that the piston rod extends from the oil cylinder barrel. When the piston rod needs to be retracted into the oil cylinder barrel, the user controls the oil pump to stop running or causes the oil pump to extract hydraulic oil from the oil cylinder barrel, thereby causing the spring to release elastic potential energy, so that the piston rod can slide and retract into the oil cylinder barrel. The piston rod can be driven by oil in and out through an oil hole, thereby reducing the steps of installing multiple oil pipes on the oil cylinder barrel and streamlining the structure of the oil cylinder.

[0017] Optionally, an end cover is detachably connected to the oil cylinder barrel, a through hole is opened in the middle of the end cover, the piston rod is inserted into the through hole of the end cover, and the end cover is threadedly connected to the end of the oil cylinder barrel.

[0018] By adopting the above technical solution, an end cover is arranged on the cylinder barrel, so that the end cover is arranged at the end of the cylinder barrel. When the hydraulic oil enters the oil chamber through the oil hole, the hydraulic oil has a probability of leaking from between the cylinder barrel and the piston rod. When the hydraulic oil leaks, the end cover can play a sealing role and reduce the probability of hydraulic oil leakage, thereby improving the airtightness of the cylinder barrel.

[0019] Optionally, a connecting portion is provided on the end cover, a cross section of the connecting portion is a regular hexagon, and the connecting portion is coaxially arranged with the end cover.

[0020] By adopting the above technical solution and providing a connecting portion on the end cover, a user can achieve the effect of rotating the end cover by clamping a wrench on the connecting portion, thereby facilitating the user to install the end cover on the cylinder barrel.

[0021] Optionally, a cylinder seat is fixedly connected to one end of the oil cylinder barrel away from the piston rod, and the cylinder seat is a shaft seat structure, and the end of the oil cylinder barrel is rotatably connected to the frame through the cylinder seat.

[0022] By adopting the above technical solution, by setting a cylinder seat at the end of the cylinder barrel, the user can rotate the cylinder barrel and connect it to the frame through the cylinder seat. The user can rotate the cylinder barrel and adjust the direction of the tool, which makes it convenient for the user to control the tool feed and remove the insulating splint.

[0023] In summary, the beneficial technical effects of this application are:

[0024] 1. By sliding the piston rod in the cylinder barrel, the hydraulic oil can push the piston rod to make the piston rod move back and forth in the cylinder barrel. By setting a spring in the cylinder barrel, when the piston rod extends in the cylinder barrel, the piston rod drives the tool to insert into the insulating splint and the rail. The speed of the tool feeding is slow, thereby reducing the probability of the tool breaking when the adhesive layer is damaged. At this time, the spring stretches and accumulates elastic potential energy. When the insulating splint is removed from the rail, the user controls the piston rod to slide into the cylinder barrel. At this time, the spring can pull the piston rod, so that the piston rod can drive the tool to retract quickly, thereby increasing the speed of the tool retraction, making it convenient for the user to retract the tool and continue the removal of other insulating splints, thereby improving work efficiency;

[0025] 2. By opening an oil chamber at the end of the piston rod, the spring can be inserted into the oil chamber and connected to the piston rod, so that a longer spring can be installed in the cylinder barrel, further increasing the speed at which the piston rod retracts into the cylinder barrel, so that the tool can be quickly retracted after removing the insulating splint;

[0026] 3. By arranging an end cover on the cylinder barrel, the end cover is arranged at the end of the cylinder barrel. When the hydraulic oil enters the oil chamber through the oil hole, the hydraulic oil has a probability of leaking from between the cylinder barrel and the piston rod. When the hydraulic oil leaks, the end cover can play a blocking role and reduce the probability of hydraulic oil leakage, thereby improving the airtightness of the cylinder barrel.

The cylinder barrel 1 is a cylindrical structure. A blind hole is opened on one end surface of the cylinder barrel 1. The piston rod 2 is inserted into the blind hole of the cylinder barrel 1. The piston rod 2 is a cylindrical structure. A blind hole is opened on one end surface of the piston rod 2 to form an oil chamber 21. The piston rod 2 has an oil chamber 21 and one end is inserted into the cylinder barrel 1. The spring 3 is arranged in the oil chamber 21. One end of the spring 3 is fixed on the piston rod 2, and the other end is fixed on the cylinder barrel 1. An oil hole 12 is opened on the cylinder barrel 1. One end of the oil hole 12 is located on the outer wall of the cylinder barrel 1, and the other end is opened on the cylinder barrel At the bottom of the blind hole 1, an oil passage pipe 11 is fixedly connected to the outer wall of the oil cylinder barrel 1. The user can make the hydraulic oil enter the oil cylinder barrel 1 and fill it into the oil chamber 21 by connecting the pipeline seal to the oil passage pipe 11. The hydraulic oil pushes the piston rod 2 to make the piston rod 2 slide in the oil cylinder barrel 1. When the piston rod 2 slides, it pulls the spring 3 to extend the spring 3. When the user controls the oil pump to stop running, the spring 3 contracts and drives the piston rod 2 to slide into the oil cylinder barrel 1. At this time, the piston rod 2 can press the hydraulic oil in the oil chamber 21 out, and then the hydraulic oil in the oil cylinder barrel 1 is discharged along the oil hole 12.

[0036] Reference Figure 2 and Figure 3 The oil hole 12 is located at one end of the oil cylinder 1 and is coaxially arranged with the oil cylinder 1. Rings are respectively connected to both ends of the spring 3. The end of the spring 3 is detachably connected to a hook 31. The user can fix the two hooks 31 in the oil cylinder 1 and the piston rod 2 respectively, so that the spring 3 can be detachably connected to the oil chamber 21, which is convenient for the user to replace and maintain the spring 3.

[0037] Reference Figure 3 The end of the hook 31 is connected with a bolt, and the user can fix the hook 31 in the cylinder barrel 1 or the piston rod 2 through the bolt. The length direction of the spring 3 is parallel to the length direction of the cylinder barrel 1, and the spring 3 is coaxially arranged with the cylinder barrel 1.

[0038] Reference Figure 2 The end of the piston rod 2 is fixedly connected to a connection seat 22, and the connection seat 22 is used to install a tool. The outer end surface of the oil cylinder barrel 1 is fixedly connected to a cylinder seat 13, and the cylinder seat 13 is a shaft seat structure. The user can rotate the end of the oil cylinder barrel 1 to connect it to the removal device through the cylinder seat 13, so that the user can rotate the oil cylinder barrel 1 and adjust the extension direction of the piston rod 2.

The end cover 4 is provided at the end of the oil cylinder barrel 1 and is connected to the oil cylinder barrel 1 by threads. A connecting portion 41 is provided on the outer end surface of the end cover 4, and the cross-section of the connecting portion 41 is a regular hexagon. The connecting portion 41 and the end cover 4 are coaxially arranged, and the user can use a wrench to clamp on the connecting portion 41, thereby rotating the end cover 4 and installing the end cover 4 on the oil cylinder barrel 1.

[0040] Reference Figure 2 The oil cylinder 1 is sealed with the piston rod 2, and a sealing ring is provided at the end of the piston rod 2. When the hydraulic oil enters the oil chamber 21, the probability of hydraulic oil leaking from between the oil cylinder 1 and the piston rod 2 can be reduced. A sealing ring is provided on the end cover 4, which improves the sealing performance of the oil cylinder 1. When the hydraulic oil leaks from between the oil cylinder 1 and the piston rod 2, the end cover 4 has a blocking effect, which can reduce the probability of hydraulic oil flowing out, so that the piston rod 2 can continue to push the tool to feed.
