Abstract
Description
Technical Field
[0001] This utility model relates to the field of hydraulic rail shear technology, and in particular to a hydraulic rail shear that is easy to adjust in position. Background Technology
[0002] Hydraulic rail shears are specialized equipment for cutting rails. They are suitable for rail removal and scrap rail processing in railway systems. Through a hydraulic system, they provide powerful shearing force, enabling fast and efficient rail cutting and improving work efficiency.
[0003] Once the existing hydraulic rail shear is connected and fixed to the excavator, the shear head cannot be turned. As a result, in actual application, the shearing operation can only be achieved by adjusting the position of the excavator itself, which makes the entire shearing process time-consuming and labor-intensive. Utility Model Content
[0004] The purpose of this utility model is to solve the technical problems mentioned above, and to propose a hydraulic rail shear that is easy to adjust in position.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a hydraulic rail shear for easy position adjustment, comprising a hollow cylinder and a U-shaped frame. Two connecting plates are fixedly installed on the top surface of the U-shaped frame. Two shear heads are rotatably connected to the bottom surface of the hollow cylinder. A hydraulic cylinder is fixedly installed on the top inner wall surface of the hollow cylinder. A lifting plate is fixedly installed at the output end of the hydraulic cylinder. Two hinge plates are hinged to the bottom surface of the lifting plate. The end of each hinge plate away from the lifting plate is hinged to one of the shear heads. A steering device is provided between the two inner walls of the U-shaped frame. The steering device includes a rotating shaft rotatably connected between the two inner walls of the U-shaped frame. A rotating plate is fixedly installed on the outer wall surface of the rotating shaft. A socket is fixedly installed on the top surface of the hollow cylinder. The rotating plate and the socket are movably connected. Two fixed plates are fixedly installed on one side surface of the U-shaped frame. A threaded rod is rotatably connected between the two fixed plates. A motor is fixedly installed on the surface of one of the fixed plates. The output end of the motor is fixedly connected to the threaded rod. The motor drives the threaded rod to rotate.
[0006] Preferably, a sliding rod is fixedly installed between the two fixed plates, and a movable plate is threadedly connected to the surface of the threaded rod. The threaded rod serves to move the movable plate along the surface of the sliding rod.
[0007] Preferably, a rack is fixedly mounted on the bottom surface of the movable plate, and a gear is fixedly mounted on the outer wall surface of the rotating shaft, with the rack and gear meshing with each other. The rack serves to drive the gear to rotate.
[0008] Preferably, the socket has a limiting device on its side, the limiting device including an extension rod, the extension rod being fixedly installed on the side of the socket, a sliding plate being slidably connected to the surface of the extension rod, a plug rod being fixedly installed on the surface of the sliding plate, and a socket hole being formed on the surface of the rotating plate. The plug rod and socket hole effectively confine the rotating plate inside the socket.
[0009] Preferably, a circular plate is fixedly mounted on the surface of the extension rod away from the socket, and a spring is fixedly mounted between the circular plate and the sliding plate. The spring serves to limit the position of the sliding plate on the surface of the rod.
[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0011] 1. In this utility model, by setting a steering device, when the device is needed, the entire device is first connected to the excavator using a connecting plate. Then, the hydraulic cylinder is started, which drives the lifting plate to move. The movement of the lifting plate drives the hinge plate to move, and the movement of the hinge plate pulls the shear head closer to clamp it, thus realizing the shearing function. When it is necessary to turn the shear head during use, the motor is started first. The motor drives the threaded rod to rotate, which drives the movable plate to move on the surface of the slide rod. The movement of the movable plate on the surface of the slide rod drives the rack to move. The rack moves and meshes with the gear, thereby causing the rotating shaft to rotate. The rotation of the rotating shaft drives the rotating plate to rotate, which drives the hollow cylinder to rotate. The rotation of the hollow cylinder ultimately drives the shear head to rotate. When the shear head rotates to a suitable angle, the motor is turned off. Then, through the cooperation of the above structure, the shear head can realize the steering operation, thereby improving the convenience of the device when shearing steel rails.
[0012] 2. In this utility model, by setting a limiting device, when the entire shearing system needs to be replaced, firstly, the sliding plate is slid, causing the sliding plate to move on the surface of the extension rod. The movement of the sliding plate on the surface of the extension rod will compress the spring, causing the spring to be compressed. At the same time, the movement of the sliding plate on the surface of the extension rod will also drive the insertion rod to move. The movement of the insertion rod will cause it to move out of the insertion hole. The separation of the insertion rod and the insertion hole will cause the rotating plate to lose its limiting position inside the socket. At this time, the hollow cylinder can be pulled down. The movement of the hollow cylinder will drive the socket to move. The movement of the socket will cause the rotating plate to move out of its interior, thereby completing the disassembly of the hollow cylinder. Through the cooperation of the above structure, when the entire shearing system malfunctions or is damaged, the hollow cylinder can be disassembled, thereby facilitating the replacement of the shearing system and improving the practicality of the device.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0022] Please see Figure 1-5 This utility model provides a technical solution: a hydraulic rail shear that is easy to adjust, including a hollow cylinder 1 and a U-shaped frame 4. Two connecting plates 5 are fixedly installed on the top surface of the U-shaped frame 4. Two shear heads 6 are rotatably connected to the bottom surface of the hollow cylinder 1. A hydraulic cylinder 7 is fixedly installed on the top inner wall surface of the hollow cylinder 1. A lifting plate 8 is fixedly installed at the output end of the hydraulic cylinder 7. Two hinge plates 9 are hinged to the bottom surface of the lifting plate 8. The end of the hinge plate 9 away from the lifting plate 8 is hinged to the shear head 6.
[0023] The specific settings and functions of its steering device 2 and limiting device 3 will be explained in detail below.
[0024] In this embodiment: a steering device 2 is provided between the inner walls of both sides of the U-shaped frame 4. The steering device 2 includes a rotating shaft 201, which is rotatably connected between the inner walls of both sides of the U-shaped frame 4. A rotating plate 202 is fixedly installed on the outer wall surface of the rotating shaft 201. A socket 203 is fixedly installed on the top surface of the hollow cylinder 1. The rotating plate 202 and the socket 203 are movably connected. Two fixing plates 204 are fixedly installed on one side surface of the U-shaped frame 4. A threaded rod 205 is rotatably connected between the two fixing plates 204. A motor 206 is fixedly installed on the surface of one of the fixing plates 204. The output end of the motor 206 is fixedly connected to the threaded rod 205.
[0025] In this embodiment, the motor 206 is configured to drive the threaded rod 205 to rotate.
[0026] Specifically, a slide bar 207 is fixedly installed between the two fixed plates 204, and a movable plate 208 is threadedly connected to the surface of the threaded rod 205.
[0027] In this embodiment, the threaded rod 205 serves to move the movable plate 208 on the surface of the slide rod 207.
[0028] Specifically, a rack 209 is fixedly installed on the bottom surface of the movable plate 208, and a gear 210 is fixedly installed on the outer wall surface of the rotating shaft 201. The rack 209 and the gear 210 mesh with each other. The rack 209 drives the gear 210 to rotate.
[0029] In this embodiment: a limiting device 3 is provided on the side of the socket 203. The limiting device 3 includes an extension rod 31. The extension rod 31 is fixedly installed on the side of the socket 203. A sliding plate 32 is slidably connected to the surface of the extension rod 31. A plug rod 33 is fixedly installed on the surface of the sliding plate 32. A plug hole 34 is opened on the surface of the rotating plate 202. When the entire shearing system needs to be replaced, first slide the slide plate 32, causing it to move on the surface of the extension rod 31. This movement compresses the spring 36, and simultaneously, the slide plate 32 moves the insertion rod 33, causing it to move out of the insertion hole 34. The separation of the insertion rod 33 and the insertion hole 34 causes the rotating plate 202 to lose its limit within the socket 203. At this point, the hollow cylinder 1 can be pulled down, causing the socket 203 to move. This movement of the socket 203 then moves the rotating plate 202 out of its interior, thus completing the disassembly of the hollow cylinder 1. Through the coordination of the above structures, when the entire shearing system malfunctions, the hollow cylinder 1 can be disassembled, facilitating the replacement of the shearing system and improving the practicality of the device.
[0030] Specifically, a circular plate 35 is fixedly installed on the surface of the extension rod 31 away from the socket 203, and a spring 36 is fixedly installed between the circular plate 35 and the sliding plate 32.
[0031] In this embodiment, the spring 36 serves to limit the position of the slide plate 32 on the surface of the slide bar 207.
[0032] Working principle: By setting up the steering device 2, when the device is needed, first connect the entire device to the excavator using the connecting plate 5, then start the hydraulic cylinder 7. The hydraulic cylinder 7 starts and drives the lifting plate 8 to move, which in turn drives the hinge plate 9 to move. The hinge plate 9 pulls the shear head 6 to approach and clamp, realizing the shearing function. When it is necessary to turn the shear head 6 during use, first start the motor 206. The motor 206 starts and drives the threaded rod 205 to rotate, which in turn drives the movable plate 208 to slide on the slide rod 2. The surface of 07 moves, the movable plate 208 moves on the surface of the slide bar 207, driving the rack 209 to move. The rack 209 moves and meshes with the gear 210, thereby causing the rotating shaft 201 to rotate. The rotation of the rotating shaft 201 drives the rotating plate 202 to rotate, the rotation of the rotating plate 202 drives the hollow cylinder 1 to rotate, and the rotation of the hollow cylinder 1 ultimately drives the shear head 6 to rotate. When the shear head 6 rotates to a suitable angle, the motor 206 is turned off. Then, through the cooperation of the above structure, the shear head 6 can realize the turning operation, thereby improving the convenience of the device when cutting the rail. When the entire shearing system needs to be replaced, first slide the slide plate 32, causing it to move on the surface of the extension rod 31. This movement compresses the spring 36, and simultaneously, the slide plate 32 moves the insertion rod 33, causing it to move out of the insertion hole 34. The separation of the insertion rod 33 and the insertion hole 34 causes the rotating plate 202 to lose its limit within the socket 203. At this point, the hollow cylinder 1 can be pulled down, causing the socket 203 to move. This movement of the socket 203 then moves the rotating plate 202 out of its interior, thus completing the disassembly of the hollow cylinder 1. Through the coordination of the above structures, when the entire shearing system malfunctions, the hollow cylinder 1 can be disassembled, facilitating the replacement of the shearing system and improving the practicality of the device.
