Description

Technical Field

[0001] This utility model relates to the field of coal mine safety engineering technology, and in particular to the shock-absorbing base structure of an underground coal mine inspection robot. Background Technology

[0002] Currently, routine inspections and checks of underground return airways and electrical equipment in coal mines are mainly carried out manually, which presents numerous problems. These include heavy workloads and high repetition rates for inspectors; a lack of advance prediction, leading to delayed responses to anomalies and potential accidents; and the presence of toxic and harmful gases and safety hazards in some working environments, which can easily harm personnel. As the coal industry gradually achieves "mechanization replacing manpower and automation reducing manpower," the requirements for safe and efficient coal mine production are constantly increasing. Therefore, utilizing robotics to enhance the intelligence level of coal mines has become an inevitable trend. Thus, it is necessary to design a vibration-damping base structure for underground coal mine inspection robots.

[0003] To this end, patent CN208703450U discloses a monitor shock-absorbing base structure, including a base plate and a bottom plate. The base plate is vertically connected to two upright plates at both ends. Slide rails are vertically opened at the middle positions of opposite sides of the upright plates. Slider blocks that are slidably connected to the slide rails are connected to the left and right ends of the bottom plate. Springs are equidistantly connected between the base plate and the bottom plate. A rotating rod is rotatably connected to the middle position of the bottom plate through a bearing, and a support plate is connected through the top of the rotating rod. The upper left and right ends of the support plate are connected to a mounting box through a telescopic mechanism. A top cover is bolted to the upper part of the mounting box. The monitor body is set on the top cover. In this invention, springs are equidistantly connected between the base plate and the bottom plate. The cooperation of the springs, slide rails and sliders can achieve a buffering and shock-absorbing effect, thereby further increasing the stability of the monitor body.

[0004] While the aforementioned shock-absorbing base structure facilitates cushioning and shock absorption during use, it is inconvenient to guide the lifting and lowering of the buffer spring during shock absorption, making it difficult to ensure the stability of the base during cushioning and shock absorption. Therefore, it is necessary to design a shock-absorbing base structure for a coal mine underground inspection robot. Utility Model Content

[0005] The purpose of this utility model is to provide a shock-absorbing base structure for an underground inspection robot in coal mines, in order to solve the defects of existing shock-absorbing base structures for inspection robots, which make it inconvenient to guide the lifting and lowering of the buffer spring and to ensure the stability of the base during buffering and shock absorption.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a shock-absorbing base structure for a coal mine underground inspection robot, including a support base;

[0007] The bottom of the support base is fixed with an anti-slip structure;

[0008] Each of the support bases has a buffer structure fixed at the corner of its top, and each of the buffer structures has a top seat fixed at its top.

[0009] Guide structures are provided on both sides above the support base. The guide structures include first balance bars on both sides above the support base, and second balance bars on one side of each first balance bar. A connecting bolt passes through the middle of each first balance bar and second balance bar. A top block is hinged to the top of each first balance bar and second balance bar, and a bottom block is hinged to the bottom of each first balance bar and second balance bar.

[0010] Furthermore, the anti-slip structure includes an adhesive layer, a rubber layer, and anti-slip strips. The adhesive layer is fixed to the bottom end of the support base, the bottom end of the adhesive layer is fixed with a rubber layer, and the bottom end of the rubber layer is uniformly fixed with anti-slip strips.

[0011] Furthermore, the anti-slip strips are evenly distributed at the bottom end of the rubber layer.

[0012] Furthermore, the buffer structure includes a base plate, a damper, a spring, and a top plate. The base plates are all fixed at the corner positions of the top of the support base. A damper is fixed to the top of each base plate. A spring is provided on the outer side of each damper. The top of each damper is fixed to the top of each damper.

[0013] Furthermore, the central axis of the damper and the central axis of the spring are collinear, and the spring is symmetrically distributed on both sides of the support.

[0014] Furthermore, the first and second balance bars are distributed in a crisscross pattern, with both the first and second balance bars symmetrically distributed on both sides of the support base.

[0015] Furthermore, the top block and the top seat are slidably connected, and the bottom block and the support seat are slidably connected.

[0016] The shock-absorbing base structure for the underground inspection robot in coal mines provided by this utility model has the following advantages:

[0017] By setting up a guide structure, when the top seat vibrates and rises, the first balance bar and the second balance bar cross each other under the action of the sliding connection between the top block and the top seat and the sliding connection between the bottom block and the support seat, which can ensure the stability of the top seat when it rises and falls. This avoids the top seat from being difficult to keep stable when it rises and falls due to the different forces of multiple sets of springs. This realizes that the device has the function of supporting and guiding the top seat, and improves the stability of the vibration damping base structure of the coal mine underground inspection robot during use.

[0018] By incorporating an anti-slip structure, the bottom of the support base can be protected under the protective effect of the rubber layer, preventing wear on the bottom of the support base. The anti-slip strips can also improve the stability of the rubber layer when in contact with other components, preventing slippage. This device achieves convenient protection and anti-slip functions, improving the convenience and stability of the shock-absorbing base structure of the coal mine underground inspection robot during use.

[0019] By incorporating a buffer structure, the top seat can be cushioned and damped by the spring's buffering action. The stability of the spring during buffering can be improved by the guiding action of the damper. This enables the device to have a buffering and damping function, thereby enhancing the safety of the vibration damping base structure of the coal mine underground inspection robot during use.

Detailed Implementation

[0026] 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.

[0027] Please see Figures 1-5 The shock-absorbing base structure for the coal mine underground inspection robot provided by this utility model includes a support base 1.

[0028] Reference Figures 1-5 The bottom end of the support base 1 is fixed with an anti-slip structure 2. The anti-slip structure 2 includes an adhesive layer 21, a rubber layer 22 and anti-slip strips 23. The adhesive layer 21 is fixed to the bottom end of the support base 1. The bottom end of the adhesive layer 21 is fixed with a rubber layer 22. The bottom end of the rubber layer 22 is uniformly fixed with anti-slip strips 23. The anti-slip strips 23 are evenly distributed at the bottom end of the rubber layer 22.

[0029] The rubber layer 22 has certain wear-resistant and anti-slip properties, which can protect the bottom of the support 1. The anti-slip strips 23 are evenly distributed at the bottom of the rubber layer 22, which increases the friction when the rubber layer 22 comes into contact with other components and improves the stability of the rubber layer 22 when it is placed in contact with other components.

[0030] Reference Figures 1-5 Each support base 1 has a buffer structure 3 fixed at the corner of its top end. The buffer structure 3 includes a base plate 31, a damper 32, a spring 33, and a top plate 34. The base plate 31 is fixed at the corner of the top end of the support base 1. The top of the base plate 31 is fixed with a damper 32. The outside of the damper 32 is provided with a spring 33. The top of the damper 32 is fixed with a top plate 34. The central axis of the damper 32 and the central axis of the spring 33 are collinear. The springs 33 are symmetrically distributed on both sides of the support base 1. The top of the buffer structure 3 is fixed with a top seat 4.

[0031] If swaying occurs during the movement of support base 1 and top base 4, spring 33 will be compressed, thereby converting the impact force into elastic potential energy and storing it. Subsequently, spring 33 will rebound and release the stored energy, allowing support base 1 and top base 4 to pass relatively smoothly, thus playing a role in buffering and shock absorption for support base 1 and top base 4.

[0032] Reference Figures 1-5 Guide structures 5 are provided on both sides above the support base 1. The guide structures 5 include first balance bars 51 provided on both sides above the support base 1, and second balance bars 55 provided on one side of each first balance bar 51. A connecting bolt 54 passes through the middle of each first balance bar 51 and second balance bar 55. A top block 52 is hinged to the top of each first balance bar 51 and second balance bar 55, and a bottom block 53 is hinged to the bottom of each first balance bar 51 and second balance bar 55. The first balance bars 51 and second balance bars 55 are distributed intersectingly. The first balance bars 51 and second balance bars 55 are symmetrically distributed on both sides of the support base 1. The top block 52 and the top seat 4 are slidably connected, and the bottom block 53 and the support base 1 are slidably connected.

[0033] When the top seat 4 shakes, it will rise and fall. When the top seat 4 rises and falls, the distance between the support seat 1 and the top seat 4 will change accordingly. The top block 52 is slidably connected to the bottom of the top seat 4, and the bottom block 53 is slidably connected to the top of the support seat 1. Under the connection of the connecting bolt 54, the included angle between the first balance bar 51 and the second balance bar 55 can be changed, so that the first balance bar 51 and the second balance bar 55 can be automatically adjusted according to the distance between the support seat 1 and the top seat 4. It can support and guide both sides of the top seat 4, ensuring that the top seat 4 remains stable when it vibrates and rises.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
