Description

Technical Field

[0001] This invention relates to the field of track component maintenance devices, and in particular to a track vibration damping component installation device. Background Technology

[0002] To reduce noise during vehicle operation, rubber pads are often placed between the track and the sleepers. However, when replacing these rubber pads or sleepers, the gap between the sleepers and the rails is small, making replacement inconvenient. It is necessary to temporarily push out part of the ballast under the sleepers and then backfill it after replacement. The existing ballast removal device uses a method of shoveling out a large amount of ballast, which takes a long time and has low work efficiency. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a track vibration damping accessory installation device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A track vibration damping accessory installation device includes a track trolley, a support frame fixedly connected to the middle of the track trolley, a lifting device provided on the support frame, a combing device provided at the bottom of the lifting device, the combing device including a support plate, support rods rotatably connected to both sides of the bottom of the support plate, the support rods being fixedly connected to an installation plate, insertion holes spaced apart on the bottom of the installation plate, a lever slidably connected in the insertion holes, and a support spring fixedly connected between the upper end of the lever and the bottom of the insertion hole.

[0006] Preferably, the lifting device includes a guide column and a hydraulic cylinder. The guide column is slidably connected to the support frame, the hydraulic cylinder is fixedly connected to the upper side of the support frame, the lower end of the extension rod of the hydraulic cylinder and the lower end of the guide column are jointly fixedly connected to the hanging plate, and the support plate is installed at the bottom of the hanging plate.

[0007] Preferably, the support plate is hinged to the bottom of the hanging plate, the bottom of the hanging plate is hinged to the swing cylinder, the telescopic rod of the swing cylinder is hinged to the support plate, two hanging rods are fixedly connected to the bottom of the hanging plate, a push plate is fixedly connected to the bottom of the hanging rods, and a rubber pad is fixedly connected to the bottom of the push plate.

[0008] Preferably, the mounting plate, the socket, and the lever have corresponding arc-shaped structures.

[0009] Preferably, the outer arc surface of the actuating lever is provided with several slots.

[0010] Preferably, a rubber plate is fixedly connected inside the right-angle slot, and the rubber plate extends to the outside of the right-angle slot.

[0011] Preferably, the support rod is fixedly connected to the diagonal rod, and the bottom of the support plate is hinged to the first hydraulic cylinder, which is hinged to the diagonal rod.

[0012] The advantages of this invention are as follows: The track vibration damping accessory installation device provided by this invention uses a hydraulic cylinder to lower the support plate, and the actuating rods at the bottom of the mounting plates on both sides are inserted into the gaps of the ballast gravel. The actuating rods that are blocked by the gravel are passively retracted into the insertion holes. As the mounting plate rotates outward, the extended actuating rods push some gravel outward, reducing the density of gravel around the sleepers, thereby facilitating the falling of the sleepers.

[0013] Furthermore, during the latter half of the installation plate's rotation, as the actuating rod is moved from the gravel and eventually inserted vertically into the gravel pile, it gradually tilts. This causes the actuating rod, which was initially partially blocked, to pop out again due to the change in angle, aided by the support spring. This facilitates the subsequent rotation of the installation plate, pushing the gravel into and compressing it to the bottom of the sleepers. During this process of pushing the gravel outwards, the amount of gravel pushed out is small because some actuating rods do not extend, requiring the downward pressure of the sleepers. During backfilling, the sleepers are already raised, and at this point, additional actuating rods are needed to push excess gravel towards the bottom and edges of the sleepers, ensuring dense filling and providing good support.

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0019] like Figure 1-4 As shown, the present invention provides a track vibration damping accessory installation device, including a track trolley 1. The front end of the track trolley 1 is provided with a power box for the track trolley 1 to travel on the track. A support frame 2 is fixedly connected to the middle of the track trolley 1. The support frame 2 is provided with a lifting device 3. The lifting device 3 includes a guide column 31 and a hydraulic cylinder 32. The guide column 31 is slidably connected to the support frame 2. The hydraulic cylinder 32 is fixedly connected to the upper side of the support frame 2. The lower end of the telescopic rod of the hydraulic cylinder 32 and the lower end of the guide column 31 are jointly fixedly connected to a hanging plate 33.

[0020] The bottom of the lifting device 3 is provided with a combing device 4. The combing device 4 includes a support plate 41, which is installed at the bottom of the hanging plate 33. Support rods 42 are rotatably connected to both sides of the bottom of the support plate 41. The support rods 42 are fixedly connected to the inclined rods 421. The bottom of the support plate 41 is hinged to a first hydraulic cylinder 422, which is hinged to the inclined rods 421. The support rods 42 are fixedly connected to a mounting plate 43. Insertion holes 44 are provided at intervals at the bottom of the mounting plate 43. A toggle rod 45 is slidably connected in the insertion holes 44. A support spring 46 is fixedly connected between the upper end of the toggle rod 45 and the bottom of the insertion hole 44.

[0021] In this embodiment, the track trolley 1 moves to the location where the sleepers or vibration damping pads need to be replaced. The support plate 41 is lowered using the hydraulic cylinder 32. The actuating rods 45 at the bottom of the mounting plates 43 on both sides are inserted into the gaps in the ballast gravel. Part of the actuating rods 45 that are blocked by the gravel are passively retracted into the insertion holes 44. As the mounting plate 43 rotates outward, the extended actuating rods 45 push some of the gravel outward, reducing the density of gravel around the sleepers and facilitating their descent. Furthermore, in the latter half of the rotation of the mounting plate 43, the actuating rods 45 are moved from the gravel and ultimately, the actuating rods 45 move from vertical insertion... As the material is inserted into the gravel pile, it gradually tilts, causing the partially blocked actuating rods 45 to pop out again due to the change in angle, supported by the springs 46. This facilitates the subsequent rotation of the mounting plate 43, which pushes the gravel into and compresses it to the bottom of the sleepers. During this process, when the gravel is pushed out, the amount of gravel pushed out is small because some actuating rods 45 do not extend. This requires the downward pressure of the sleepers. When backfilling, the sleepers are raised, and at this time, the extra actuating rods 45 are needed to push the excess gravel to the bottom and edges of the sleepers, making the filling dense and providing good support.

[0022] In one embodiment of the present invention, the support plate 41 is hinged to the bottom of the hanging plate 33, and the bottom of the hanging plate 33 is hinged to the swing cylinder 34. The telescopic rod of the swing cylinder 34 is hinged to the support plate 41. Two hanging rods 35 are fixedly connected to the bottom of the hanging plate 33. A push plate 36 is fixedly connected to the bottom of the hanging rods 35. A rubber pad is fixedly connected to the bottom of the push plate 36. The hinge point between the support plate 41 and the hanging plate 33 is located in the middle, and the swing cylinder 34 is located on the side. The extension or retraction of the swing cylinder 34 causes the support plate 41 to swing relative to the hanging plate 33 by a forward and reverse angle.

[0023] Furthermore, support rods 411 are hinged to both sides of the support plate 41, and a support plate 412 is fixedly connected to the lower end of the support rods 411. A protective rubber pad is fixedly connected to the upper side of the support plate 412 to provide cushioning protection and anti-slip function.

[0024] When the track trolley 1 moves, the support rod 411 is tied to the support frame 2 with a rope. When it reaches the position where the sleeper or vibration damping pad needs to be replaced, the personnel remove the ballast rubble from both ends of the sleeper, lower the support rod 411, and use the support plate 412 to support both ends of the sleeper. This allows the sleeper to fall onto the support plate 412 when the ballast rubble at the bottom of the sleeper is lowered. This makes it easier to raise the sleeper after the vibration damping pad is installed by the support plate 411 and the support plate 412. This makes it easier to refill the bottom of the sleeper with ballast rubble, reducing the intensity of manual labor. In addition, the vibration damping pad is pre-compressed, which makes the space at the bottom of the sleeper sufficient, so that after the device is removed, the ballast rubble provides good support for the falling sleeper.

[0025] In this embodiment, the extension or retraction of the swing cylinder 34 causes the support plate 41 to swing relative to the hanging plate 33 in opposite directions. The push plate 36 at the bottom of the support plate 41 pushes the sleeper from different directions. That is, when the right end of the top of the sleeper is subjected to an inclined pushing force, it is convenient for the ballast gravel at the bottom of the sleeper to slide to the outside of the bottom of the sleeper. By pushing alternately, the ballast gravel directly below the bottom of the sleeper slides to both sides, so that the sleeper has space to descend, thereby increasing the distance between the sleeper and the rail, increasing the working space, and facilitating the replacement of the sleeper or vibration damping pad.

[0026] In one embodiment of the present invention, the mounting plate 43, the insertion hole 44, and the actuating rod 45 are in the form of corresponding arc-shaped structures. The outer arc surface of the actuating rod 45 is provided with a plurality of slots 451. The included angle of the slots 451 is 60-90 degrees. That is, when the included angle of the slots 451 is 90 degrees, the vertical sidewall of the slots 451 is set along the diameter direction of the actuating rod 45. The rubber plate 452 is fixedly connected to the right-angle slots 451 by screws, so that the rubber plate 452 is easy to replace. The rubber plate 452 extends to the outside of the right-angle slots 451, actuates the gravel, and through friction, facilitates the actuation of the gravel to the bottom of the raised sleeper.

[0027] In this embodiment, when the mounting plate 43 rotates in the reverse direction, the extended actuating rod 45 gathers the ballast gravel towards the bottom of the sleeper, allowing the ballast gravel to be backfilled into the bottom of the sleeper to form support. The rubber plate 452 increases the friction of the gravel, making it easier to move the gravel to fill the raised bottom of the sleeper. Once the bottom of the sleeper is filled, the gravel slides out between two adjacent actuating rods 45, thus facilitating the quick replacement of the vibration damping pads or sleepers.

[0028] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
