[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present 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 only used to explain the present invention and are not intended to limit the present invention.

[0023] like Figure 1-5 As shown, the present invention provides a rail noise reduction pad installation device, including an installation vehicle 1, the installation vehicle 1 is provided with a through slot 11, the upper side of the installation vehicle 1 is rotatably connected to a circular shaft 12, the middle part of the circular shaft 12 is fixedly connected to a support block 2, the upper side of the support block 2 is fixedly connected to a vertical plate 3, one side of the installation vehicle 1 is fixedly connected to a control box 4, one side of the control box 4 is hingedly connected to a swing cylinder 41, the telescopic rod of the swing cylinder 41 is hingedly connected to the vertical plate 3, the support block 2 is fixedly connected to a lifting cylinder 5, the lower end of the lifting cylinder 5 is provided with a lifting seat 6, the bottom of the lifting seat 6 is provided with a push plate 7, and a side pushing device 8 is provided on both sides of the lifting seat 6.

[0024] A side plate 71 is fixedly connected to each side of the push plate 7, and each side plate 71 is fixedly connected to a clamping cylinder 72. The telescopic rod of the clamping cylinder 72 passes through the side plate 71 and is fixedly connected to the splint. When the push plate 7 drops, the two side plates 71 are separated on both sides of the sleeper. The clamping cylinder 72 extends to clamp the sleeper through the splint, making it convenient to push the sleeper to shake left and right.

[0025] The present invention is to move the installation vehicle 1 along the track that needs to be inspected to the position of the noise reduction pad that needs to be replaced. The push plate 7 is located directly above the sleeper of the noise reduction pad. The clips on the side of the rail are first removed, and the lifting cylinder 5 pushes down the lifting seat 6 and the push plate 7. The push plate 7 pushes the sleeper downward, and then the swing cylinder 41 pushes the support block 2 to rotate left and right, so that the push plate 7 is tilted relative to the sleeper. The tilted sleeper facilitates the ballast gravel directly below the sleeper to move to the outside on both sides, thereby allowing the sleeper to descend. There is enough space between the sleeper and the rail, which is convenient for cleaning the old noise reduction pad and installing a new one.

[0026] As an embodiment of the present invention, the lifting seat 6 includes a horizontal plate 61, the upper side of which is fixedly connected to the telescopic rod of the lifting cylinder 5, and the upper side of the horizontal plate 61 is fixedly connected to a guide column 62, which is slidably connected to the support block 2 and serves as a guide.

[0027] The upper side of the horizontal plate 61 is fixedly connected to the step column 63, and the step column 63 is slidably connected to the longitudinal plate 64. A limiting slide groove 65 is provided at the bottom of the longitudinal plate 64. The horizontal plate 61 is slidably connected in the limiting slide groove 65. A support spring 66 is fixedly connected between the step column 63 and the longitudinal plate 64. The bottom of the longitudinal plate 64 is fixedly connected to two suspension rods 67, and the lower ends of the two suspension rods 67 are jointly fixedly connected to the push plate 7.

[0028] The side thrust device 8 includes a spring extension rod 81, the upper end of which is hingedly connected to the horizontal plate 61 and a rotary torsion spring is provided on the hinge axis. The lower end of the spring extension rod 81 is fixedly connected to the support plate 82, and the bottom of the support plate 82 is fixedly connected to two rows of insertion rods 83, with at least six insertion rods 83 in each row.

[0029] The present invention first pushes down the lifting seat 6 as a whole through the lifting cylinder 5. After the lifting seat 6 is lowered, the push plate 7 below acts on the sleeper. Since the bottom of the sleeper is covered with ballast and gravel, the lowering height is limited. After the push plate 7 is blocked, the telescopic rod of the lifting cylinder 5 pushes the cross plate 61 down alone. After the cross plate 61 is lowered, the support plates 82 and the insertion rods 83 on both sides of the cross plate 61 push the ballast and gravel between the two sleepers outward, so that the ballast and gravel at the bottom of the sleeper have space to move outward. When there is space for outward movement, the support spring 66 plays a role of vibrating downward pressure, cooperating with the swinging cylinder 41 to swing the push plate 7, forming an outward vibration and oblique pushing effect on the ballast and gravel just below the sleeper, so that the sleeper can be lowered to a sufficient height, which is convenient for replacement operation.

[0030] As an embodiment of the present invention, the insertion rod 83 includes a rigid rod 831, the upper end of the rigid rod 831 is threadedly connected to the support plate 82, and the lower end of the rigid rod 831 is fixedly connected to the steel column 832. The lower end of the steel column 832 is conical, and the steel column 832 is elastic. When one of the steel columns 832 is inserted into the ballast gravel, it forms an avoidance. After long-term use, it is inevitable that some of the steel columns 832 will bend. When the steel column 832 is bent, it is disassembled through the rigid rod 831 and the support plate 82 for easy replacement.

[0031] As an embodiment of the present invention, the spring extension rod 81 includes a square tube 811, the lower end of the square tube 811 is slidingly connected to the square rod 812, the lower end of the square rod 812 is fixedly connected to the upper side of the support plate 82, a first ear plate 813 is fixedly connected on both sides of the square rod 812, a second ear plate 814 is fixedly connected on both sides of the square tube 811, the first ear plate 813 is fixedly connected to the guide rod 815, the guide rod 815 is slidingly connected to the second ear plate 814, and a first spring 816 is fixedly connected between the first ear plate 813 and the second ear plate 814.

[0032] The lifting cylinder 5 first moves the cross plate 61 and the side thrust device 8 vertically downward, so that the first spring 816 is compressed. When the cross plate 61 tilts under the action of the swing cylinder 41, the spring extension rod 81 of the side thrust device 8 increases its tilt angle to one side, which on the one hand forms an oblique push of the ballast gravel. On the other hand, the first spring 816 buffers and the overall inclination of the spring extension rod 81 becomes lower, making the side push easier. The insertion rod 83 pushes out part of the gravel, and the other part of the gravel leaks out from between the two insertion rods 83. There is no need to push out all the ballast gravel, but only increase the gap to facilitate the movement of the gravel at the bottom of the sleeper. At the same time, the ballast gravel is not completely transferred, so that after the subsequent replacement of the noise reduction pad is completed, the ballast can be easily backfilled directly under the sleeper.

[0033] As an embodiment of the present invention, a suspension device 9 is fixedly connected to both sides of the bottom of the installation vehicle 1, and the two suspension devices 9 are symmetrically arranged on both sides of the support block 2. Each suspension device 9 includes two vertical rods 91, and the vertical rod 91 is fixedly connected to the bottom of the installation vehicle 1. The lower ends of the two vertical rods 91 are commonly fixedly connected to the inclined rod 92, and the upper ends of the inclined rod 92 are hingedly connected to the inclined plate 93 and a first torsion spring is installed on the hinge shaft. The bottom surface of the inclined plate 93 is attached to the inclined rod 92, so that it can only rotate in one direction. The upper side of the square tube 811 is fixedly connected to the installation rod 94, and the installation rod 94 is rotatably connected to the circular column 95, and the circular column 95 is arranged corresponding to the inclined plate 93.

[0034] The upper side of the mounting vehicle 1 is fixedly connected to two bearing seats 13 , and the two bearing seats 13 are rotatably connected to the circular shaft 12 .

[0035] In the present invention, the vertical plate 3 is pushed to the left by the swing cylinder 41, and the circular column 95 on the side of the square tube 811 of the left side pushing device 8 pushes the inclined plate 93 to the upper left, and the inclined plate 93 rotates to avoid. After the circular column 95 completely pushes the inclined plate 93 away, the inclined plate 93 rotates under the action of the first torsion spring and is limited by the inclined rod 92. When the swing cylinder 41 pushes the vertical plate 3 to the right, the left side pushing device 8 is reset. Due to the supporting effect of the inclined plate 93, the inclined plate 93 cannot be reversed by the inclined rod 92, so the circular column 95 will be placed on the inclined plate 93, so that the support plate 82 and the insertion rod 83 that push the ballast gravel outward on the left side will not be reset. The side pushing device 8 on the right also uses this principle, so that the gravel on both sides of the sleeper is pushed away and stays, thereby facilitating the push-out of the gravel under the sleeper.

[0036] After the noise reduction pad on the upper side of the sleeper is replaced and installed, the bottom of the push plate 7 is clamped and lifted up, and the sleeper is attached to the bottom of the rail and installed firmly. During this process, the square tube 811 and the circular column 95 of the side push device 8 rise together, so that the circular column 95 is higher than the inclined plate 93. Under the action of the rotary torsion spring at the upper end of the square tube 811, the side push device 8 rotates as a whole toward the middle of the sleeper, thereby backfilling the gravel originally pushed out to the bottom and edge of the sleeper. The rotary torsion spring releases its elastic force after being blocked by the inclined plate 93, generating an impact force on the backfilled gravel, thereby facilitating the movement of the gravel and cooperating with manual local replenishment to improve the backfill efficiency of the gravel.

[0037] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
