[0002] Mining tunnel drilling rigs often generate significant vibrations during operation, affecting operator comfort as well as equipment stability and lifespan. To effectively reduce vibration, a vibration damping component for mining tunnel drilling rigs can be designed.

[0003] According to a public disclosure of a vibration damping device for a fully hydraulic tunnel drilling rig used in mining (publication number: CN 212642617U), it includes a column, an operating platform fixed to the upper end of the column, a tunnel drilling rig mechanism slidably connected to the top of the operating platform, the tunnel drilling rig mechanism including a mounting base, and the mounting base slidably connected to the top surface of the operating platform. A mounting rod is rotatably connected to the center of the top surface of the mounting base through a rolling bearing, and a support plate is fixed to the top of the mounting rod by screws. A vibration damping plate is provided on the upper side of the support plate.

[0004] The aforementioned method, through the cooperation between components such as mounting bases and support plates, fails to effectively absorb and mitigate the pressure caused by vibration, resulting in increased instantaneous impact on the drilling rig, which needs improvement. Utility Model Content

[0005] The purpose of this utility model is to provide a shock-absorbing component for a mining tunnel drilling rig. Through the cooperation between the L-shaped connecting frame, support seat, displacement rod and other components inside the shock-absorbing component, the displacement rod, telescopic rod and spring work together to achieve the following: when the drilling rig is subjected to vibration, the displacement rod slides up and down on the inner wall of the support seat. Through the elastic action of the spring and telescopic rod, the pressure caused by the vibration can be effectively absorbed and relieved, the instantaneous impact on the drilling rig can be reduced, the service life of the equipment can be extended, and the existing problems can be solved.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a shock-absorbing component for a mining tunnel drilling rig, comprising a drilling rig body, a drilling platform fixedly connected to the bottom of the drilling rig body, a shock-absorbing component disposed at the bottom of the drilling platform, the shock-absorbing component comprising an L-shaped connecting frame, the top of the L-shaped connecting frame being fixedly connected to the bottom of the drilling platform, a threaded groove being formed on the top of the L-shaped connecting frame, a bolt being threadedly connected to the inner wall of the threaded groove, a nut being threadedly connected to the circumferential surface of the bolt, a displacement frame rod being disposed at the bottom of the bolt, a support seat being slidably connected to the outer wall of the displacement frame rod, a telescopic rod being fixedly connected to the top of the support seat, the telescopic end of the telescopic rod being fixedly connected to the bottom of the displacement frame rod, a spring being fixedly connected to the top of the support seat, and the end of the spring away from the support seat being fixedly connected to the bottom of the displacement frame rod.

[0008] Furthermore, an auxiliary support rod is fixedly connected to the side of the displacement frame rod, and the side of the auxiliary support rod is slidably connected to the side of the support base. A control box is provided on the top of the drilling rig platform. The design of the control box is conducive to directly controlling the drilling rig to carry out operations.

[0009] Furthermore, the shock absorption components are provided in several groups, in pairs, and symmetrically arranged along the vertical central axis of the drilling rig. The L-shaped connecting frame is located at the top of the support base, and the bottom of the drilling rig body is provided with tracks and several groups of shock absorption components, which helps to improve the shock absorption effect.

[0010] Furthermore, a rebound buffer assembly is provided on the side of the support base. The rebound buffer assembly includes a short rod, one end of which is fixedly connected to the side of the displacement frame rod. A contact block is fixedly connected to the end of the short rod away from the displacement frame rod. A support rod is fixedly connected to the side of the support base. A vertical rod is fixedly connected to one end of the support rod. An obstruction block is fixedly connected to the side of the vertical rod. The obstruction block is provided to prevent the displacement frame rod and the contact block from rebounding upwards, thereby reducing the impact of the rebound on the drilling rig.

[0011] Furthermore, the obstruction block is located on the side of the contact block and on the displacement trajectory of the contact block. This design is beneficial because when the contact block moves up and down, the friction generated by the obstruction block slows down the movement speed.

[0012] Furthermore, the side of the contact block closest to the obstruction block is set in an arc shape. Several obstruction blocks are provided and arranged in a linear array on the side of the vertical rod. The arc-shaped design of the contact block is conducive to fitting the obstruction block and increasing some resistance.

[0013] Furthermore, a limiting rod is fixedly connected to the side of the support base, and the end of the limiting rod away from the support base passes through the bottom of the short rod. The design of the limiting rod is beneficial to restricting the movement trajectory of the contact block and the displacement frame rod.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model achieves the following through the cooperation between the L-shaped connecting frame, support seat, displacement rod and other components inside the shock absorption assembly: when the drilling rig is subjected to vibration, the displacement rod slides up and down on the inner wall of the support seat. Through the elastic action of the spring and the telescopic rod, the pressure caused by the vibration can be effectively absorbed and relieved, which can reduce the instantaneous impact on the drilling rig and extend the service life of the equipment.

[0016] 2. This utility model achieves the change of friction between the contact block, the obstruction block, the limit rod and other components inside the rebound buffer assembly through the mutual cooperation between them. By distinguishing between the arc surface and the non-arc surface design, the speed and impact of the up and down movement are effectively controlled. By controlling the speed of vibration rebound, the contact impact between key components such as the telescopic rod and the spring and the L-shaped connecting frame and the drilling platform is reduced.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-5 This utility model is a shock-absorbing component for a mining tunnel drilling rig, including a drilling rig body 1, a drilling platform 2 fixedly connected to the bottom of the drilling rig body 1, a shock-absorbing component 3 provided at the bottom of the drilling platform 2, the shock-absorbing component 3 including an L-shaped connecting frame 31, the top of the L-shaped connecting frame 31 fixedly connected to the bottom of the drilling platform 2, a threaded groove 32 opened on the top of the L-shaped connecting frame 31, a bolt 33 threadedly connected to the inner wall of the threaded groove 32, a nut 34 threadedly connected to the circumferential surface of the bolt 33, a displacement frame rod 36 provided at the bottom of the bolt 33, a support seat 35 slidably connected to the outer wall of the displacement frame rod 36, a telescopic rod 37 fixedly connected to the top of the support seat 35, the telescopic end of the telescopic rod 37 fixedly connected to the bottom of the displacement frame rod 36, a spring 38 fixedly connected to the top of the support seat 35, and the end of the spring 38 away from the support seat 35 fixedly connected to the bottom of the displacement frame rod 36.

[0028] An auxiliary support rod 39 is fixedly connected to the side of the displacement frame rod 36. The side of the auxiliary support rod 39 is slidably connected to the side of the support base 35. A control box 5 is installed on the top of the drilling rig platform 2. The design of the control box 5 is conducive to directly controlling the drilling rig to carry out operations.

[0029] Several sets of shock-absorbing components 3 are provided, arranged in pairs and symmetrically along the vertical central axis of the drilling rig 2. The L-shaped connecting frame 31 is located on top of the support base 35. The bottom of the drilling rig body 1 is provided with tracks 310 and several sets of shock-absorbing components 3, which helps to improve the shock absorption effect.

[0030] A rebound buffer assembly 4 is provided on the side of the support base 35. The rebound buffer assembly 4 includes a short rod 41. One end of the short rod 41 is fixedly connected to the side of the displacement frame rod 36. A contact block 42 is fixedly connected to the end of the short rod 41 away from the displacement frame rod 36. A support rod 43 is fixedly connected to the side of the support base 35. A vertical rod 44 is fixedly connected to one end of the support rod 43. An obstruction block 45 is fixedly connected to the side of the vertical rod 44. The obstruction block 45 is provided to prevent the displacement frame rod 36 and the contact block 42 from rebounding upwards, thereby reducing the impact of the rebound on the drilling rig.

[0031] The obstruction block 45 is located on the side of the contact block 42 and on the displacement trajectory of the contact block 42. This design is beneficial to reduce the moving speed by the friction generated by the obstruction block 45 when the contact block 42 moves up and down.

[0032] The side of the contact block 42 closest to the obstruction block 45 is set in an arc shape. Several obstruction blocks 45 are provided and are arranged in a linear array on the side of the vertical rod 44. The arc shape of the contact block 42 is conducive to fitting the obstruction block 45 and increasing some resistance.

[0033] A limiting rod 46 is fixedly connected to the side of the support base 35. The end of the limiting rod 46 away from the support base 35 passes through the bottom of the short rod 41. The design of the limiting rod 46 is beneficial to restricting the movement trajectory of the contact block 42 and the displacement frame rod 36.

[0034] A specific application of this embodiment is as follows: The L-shaped connecting frame 31 is initially fixedly connected to the bottom of the drilling rig 2. A threaded groove 32 is provided on the top of the L-shaped connecting frame 31. A bolt 33 is fixed to the top of the displacement rod 36. The bolt 33 is inserted into the threaded groove 32 and rotated to connect the displacement rod 36, bolt 33, and L-shaped connecting frame 31. The bolt 33 is temporarily fixed to the bottom of the L-shaped connecting frame 31 using a nut 34. The support seat 35 is slidably connected to the displacement rod 36, and a groove is provided between them. The displacement rod 36 and support seat 35 can slide up and down, but the support seat 35 and displacement rod 36 will not separate directly. Therefore, when the displacement rod 36 is connected to the L-shaped connecting frame 31, the support seat 35 is also fixed to the bottom of the L-shaped connecting frame 31. This temporarily fixes the displacement rod 36, support seat 35, telescopic rod 37, and spring 38 to the bottom of the drilling rig 2. The four support seats 35 are used to support the drilling rig 2. When the drilling rig is subjected to vibration during use, causing it to sway and shift vertically, the displacement rod 36, telescopic rod 37, and spring 38 will be subjected to the pressure from the vibration. This will cause the displacement rod 36 to slide up and down on the inner wall of the support base 35, compressing the telescopic rod 37 and spring 38 to absorb the received vibration. The vibration will gradually be released through the telescopic rod 37 and spring 38. Through the cooperation of the displacement rod 36, telescopic rod 37, and spring 38, when the drilling rig is subjected to vibration, the displacement rod 36 slides up and down on the inner wall of the support base 35. The elasticity of the spring 38 and telescopic rod 37 can effectively absorb and alleviate the pressure caused by the vibration. This vibration-damping design can reduce the instantaneous impact on the drilling rig and extend the service life of the equipment. The design of the support base 35 ensures that the displacement rod 36 will not separate from the support base 35 during the up and down sliding process, thereby maintaining the stability of the drilling rig. This reduces the excessive shaking that may occur during the operation of the drilling rig and improves the accuracy and safety of the drilling operation.

[0035] As the displacement rod 36 moves up and down, it drives the short rod 41 and contact block 42 to move up and down as well. The obstruction block 45 is located on the movement trajectory of the contact block 42. When the contact block 42 moves downward, its arc surface will first contact the obstruction block 45. The arc surface design reduces the friction between the contact block 42 and the obstruction block 45. Therefore, the first contact with the arc surface will reduce the resistance of the obstruction block 45 to the contact block 42, allowing the contact block 42 to pass through the obstruction block 45 more quickly. When the contact block 42 moves upward with the displacement rod 36, the non-arc side of the contact block 42 will first contact the obstruction block 45. The non-arc design increases the friction between the contact block 42 and the obstruction block 45, thus increasing the resistance between them. This slows down the upward rebound speed of the contact block 42 and the displacement rod 36, reducing the position. When the moving rod 36 is not subjected to vibration rebound, the impact force of the telescopic rod 37 and spring 38 on the L-shaped connecting frame 31 and the drilling platform 2 is reduced. The change in friction between the contact block 42 and the obstruction block 45 is effectively controlled by the difference between the arc surface and non-arc surface design. When the contact block 42 moves downward, the friction reduction design of the arc surface allows it to quickly pass through the obstruction block 45, reducing the impact during the up and down movement. When rebounding, the non-arc surface design increases the friction force and slows down the speed, thereby reducing the amplitude of vibration rebound. This reduces the severe impact and vibration that the drilling platform 2 and the L-shaped connecting frame 31 may experience during operation. By controlling the speed of vibration rebound, the contact impact between key components such as the telescopic rod 37 and spring 38 and the L-shaped connecting frame 31 and the drilling platform 2 is reduced, reducing wear and damage caused by severe vibration during long-term operation and effectively extending the service life of the equipment.
