Abstract
Description
Technical Field
[0001] This utility model relates to the field of paver technology, specifically to a paver support roller device. Background Technology
[0002] Tracked pavers are specialized engineering machines that spread prepared mixtures evenly on the road base. They consist of various systems that work together to complete the paving operation, including a walking system, a hydraulic system, and a material conveying system. The walking system mainly consists of track tracks, drive wheels, guide wheels, support rollers, and carrier rollers. The carrier rollers are mainly used to support the track tracks.
[0003] The existing track rollers are in fixed positions and only have the single function of supporting the upper track track, without the function of tension adjustment. Therefore, the device can only rely on the existing track tensioning device to adjust the track tension. However, the track tensioning device has a relatively complex structure, high cost, and is extremely inconvenient to install and maintain.
[0004] As disclosed in CN221954481U, a paver support roller device has three support rollers arranged around a first central axis. The top of the support rollers presses against the track chain for support. Each of the three support rollers can rotate independently around its own axis. With the cooperation of the drive motor, the first bevel gear, and the second bevel gear, the three support rollers can also rotate around the first central axis. Under the rotation of the three support rollers, the track chain can drive the track to move to a certain extent in the vertical direction, thereby realizing track tension adjustment and achieving the purpose of multi-functionality and multi-purpose support roller device. A support roller mechanism is set at each of the left and right ends above the track beam, and the two support roller mechanisms can operate independently. Through the cooperation of the two support roller mechanisms, the position of the left and right ends of the track chain can be adjusted separately, so that the track tension can be adjusted more flexibly.
[0005] However, during use, when the paver is traveling or working on uneven surfaces, the track chain will cause vibration and impact on the rollers, resulting in vibration between the rollers and the track beams, which affects the smoothness and quality of the paving.
[0006] Therefore, we urgently need to provide a paver support roller device. Utility Model Content
[0007] The purpose of this utility model is to provide a paver support roller device to solve the problem mentioned in the background art that when the paver is traveling or working on uneven road surfaces, the track chain will cause vibration and impact on the support roller, which will cause the support roller and track beam to vibrate, affecting the flatness and quality of the paving.
[0008] To achieve the above objectives, the present invention provides the following technical solution: a paver support roller device, including a track beam, wherein an auxiliary device is provided on the top of the track beam, and the auxiliary device includes a buffer unit and a limiting unit.
[0009] The buffer unit is located inside the track beam, and the limiting unit is located on the left and right sides of the top of the track beam.
[0010] The buffer unit includes a mounting plate, a roller, a damping rod, a spring, a first bracket, a push plate, and a second bracket. The mounting plate is slidably connected to the inside of the track beam. The roller is installed inside the mounting plate. The damping rod is fixedly installed on the left and right sides of the inner wall of the track beam. The spring is installed on the outside of the damping rod. The first bracket is fixedly installed at the end of the damping rod away from the inner wall of the track beam. The push plate is rotatably connected to the inside of the first bracket. The second bracket is fixedly installed on the left and right sides of the bottom of the track beam.
[0011] Preferably, the track beam has a groove inside, and the buffer units are symmetrically distributed inside the groove, which buffer the vibration of the roller.
[0012] Preferably, the inner wall of the track beam is provided with grooves on the left and right sides, and the mounting plate is provided with protrusions on the left and right sides. The protrusions are slidably connected inside the grooves. Through the cooperation of the protrusions and the grooves, the mounting plate can move vertically up and down along the track beam.
[0013] Preferably, the end of the push plate away from the first support is rotatably connected inside the second support. When the track chain causes vibration to the roller, the roller squeezes the push plate through the mounting plate, thereby causing the push plate to rotate around the first and second supports while pushing the first support to squeeze the damping rod and spring, thereby reducing the vibration of the roller and improving the flatness and quality of the paving.
[0014] Preferably, the limiting unit includes a fixed block, a threaded rod, a limiting rod, a limiting plate, and a limiting roller. The fixed block is fixedly installed on the front and rear sides of the top of the track beam. The threaded rod is rotatably connected to the upper inside of the two fixed blocks. The limiting rod is fixedly installed on the adjacent side of the two fixed blocks at the lower end of the threaded rod. The limiting plate is installed on the outside of the threaded rod and the limiting rod. The limiting roller is installed on the upper inside of the limiting plate.
[0015] Preferably, the outer surface of the threaded rod has external threads in opposite directions on both the front and rear sides. The limiting plate is threaded to the outside of the threaded rod. By rotating the threaded rod and connecting it to the front and rear limiting plates, the limiting plates can move linearly along the limiting rod, making the distance between the front and rear limiting plates equal to the width of the track track. This limits the track track on both sides, preventing the track track from moving laterally and deviating, which could cause it to detach from the support roller.
[0016] Preferably, the limiting rollers are symmetrically distributed on the left and right sides inside the limiting plate, and the limiting rollers can rotate around the inside of the limiting plate. When the limiting plate limits the track, the limiting rollers work together to reduce the friction between the limiting plate and the track track, thereby making the track track move more smoothly.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] 1. The paver's idler roller device, by setting up a buffer unit, when the track chain causes vibration to the idler roller, the idler roller is pressed against the push plate by the mounting plate, so that the push plate rotates around the first and second supports and pushes the first support to compress the damping rod and spring, thereby reducing the vibration of the idler roller and improving the smoothness and quality of paving. This solves the problem mentioned in the background technology that when the paver is traveling or working on uneven road surfaces, the track chain will cause vibration and impact on the idler roller, resulting in vibration between the idler roller and the track beam, which affects the smoothness and quality of paving.
[0019] 2. The paver roller device, by setting a limiting unit, connects the front and rear limiting plates by rotating the threaded rod, so that the limiting plates move linearly along the limiting rod, making the distance between the front and rear limiting plates equal to the width of the track track. Thus, the limiting plates limit the track track on both sides, preventing the track track from moving laterally and deviating, which would cause it to detach from the roller.

[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] Please see Figures 1-4 This utility model provides a technical solution:
[0027] Example 1:
[0028] A paver support roller device includes a track beam 1, and an auxiliary device is provided on the top of the track beam 1. The auxiliary device includes a buffer unit and a limiting unit.
[0029] The buffer unit is located inside the track beam 1. The track beam 1 has a groove, and the buffer unit is symmetrically distributed inside the groove. The buffer unit buffers the vibration of the roller 202. The limiting unit is located on the left and right sides of the top of the track beam 1.
[0030] The buffer unit includes a mounting plate 201, a roller 202, a damping rod 203, a spring 204, a first bracket 205, a push plate 206, and a second bracket 207. The mounting plate 201 is slidably connected to the inside of the track beam 1. The inner wall of the track beam 1 has grooves on both sides, and the mounting plate 201 has protrusions on both sides, which are slidably connected inside the grooves. Through the engagement of the protrusions and grooves, the mounting plate 201 moves linearly up and down along the track beam 1. The roller 202 is installed inside the mounting plate 201. The damping rod 203 is fixedly installed on the inner wall of the track beam 1 on both sides. The spring 204 is installed on the outside of the damping rod 203. The first bracket 205 is fixedly installed on the outside of the damping rod 203. The damping rod 203 is fixedly installed at one end away from the inner wall of the track beam 1. The push plate 206 is rotatably connected to the inside of the first bracket 205. The end of the push plate 206 away from the first bracket 205 is rotatably connected to the inside of the second bracket 207. When the track track causes vibration to the roller 202, the roller 202 presses the push plate 206 through the mounting plate 201. This causes the push plate 206 to rotate around the first bracket 205 and the second bracket 207, while pushing the first bracket 205 to press the damping rod 203 and the spring 204, thereby reducing the vibration of the roller 202 and improving the flatness and quality of the paving. The second bracket 207 is fixedly installed on the left and right sides of the bottom of the track beam 1.
[0031] Example 2: Based on Example 1: The limiting unit includes a fixed block 301, a threaded rod 302, a limiting rod 303, a limiting plate 304, and a limiting roller 305. The fixed block 301 is fixedly installed on the front and rear sides of the top of the track beam 1. The threaded rod 302 is rotatably connected to the upper inner part of the two fixed blocks 301. The outer surface of the threaded rod 302 has external threads in opposite directions on the front and rear sides. The limiting plate 304 is threadedly connected to the outside of the threaded rod 302. By rotating the threaded rod 302 and threading it to the two limiting plates 304, the limiting plate 304 moves linearly along the limiting rod 303, allowing the two limiting plates to move linearly. The distance between the limiting plates 304 is equal to the width of the track track, thereby limiting the track track on both sides through the limiting plates 304 to prevent the track track from moving laterally and deviating, which would cause it to detach from the support roller 202. The limiting rod 303 is fixedly installed on the side adjacent to the front and rear fixing blocks 301, located at the lower end of the threaded rod 302. The limiting rod 303 limits the movement of the limiting plate 304. The limiting plate 304 is installed on the outside of the threaded rod 302 and the limiting rod 303. The limiting roller 305 is installed inside the upper end of the limiting plate 304. The limiting roller 305 reduces the friction between the track track and the limiting plate 304.
[0032] Example 3: Based on Example 2: The limiting rollers 305 are symmetrically distributed on the left and right sides inside the limiting plate 304, and the limiting rollers 305 can rotate around the inside of the limiting plate 304. When the limiting plate 304 limits the track, the limiting rollers 305 work together to reduce the friction between the limiting plate 304 and the track track, thereby making the track track move more smoothly.
[0033] In use, the threaded rod 302 is connected to the front and rear limit plates 304 by rotating the threaded rod 302, so that the limit plates 304 move linearly along the limit rod 303, making the distance between the front and rear limit plates 304 equal to the width of the track track. When the paver is working, when the track track vibrates against the roller 202, the roller 202 presses the push plate 206 through the mounting plate 201, so that the push plate 206 rotates around the first support 205 and the second support 207, while pushing the first support 205 to press the damping rod 203 and the spring 204, thereby reducing the vibration of the roller 202 and improving the flatness and quality of the paving. At the same time, it works with the limit roller 305 to limit the two sides of the track track, preventing the track track from moving laterally and deviating, which would cause it to detach from the roller 202, thus improving the stability of the paver.
