Description

Technical Field

[0001] The utility model belongs to the technical field of mine detection, and in particular relates to a detection vehicle. Background Art

[0002] Coal is the most important solid fuel and a type of combustible organic rock. It is formed by the natural coalification process over a long period of geological time, when lush plants grew over a certain geological period, gradually accumulated into thick layers in a suitable geological environment, and were buried under water or in mud and sand.

[0003] When the coal seam is far from the surface, it is generally chosen to dig tunnels underground to mine coal, which is called underground coal mining.

[0004] In recent years, disasters such as explosions and fires in coal mines have caused serious casualties and property losses. It is very important for rescue workers to detect the on-site conditions and trapped people after the disaster.

[0005] The existing technology uses robots to detect coal mine sites. For example, a Chinese patent discloses a utility model patent named "A Portable Environmental Detection Multifunctional Robot" (authorization announcement number: CN211867820U). The user can control the movement of the moving vehicle and enter the scene after the disaster, which makes it easier for users to understand the on-site environmental information, biological conditions and location information, making it easier for subsequent users to enter the scene for rescue work, thereby improving the efficiency of the rescue work, and the entire robot has a simple structure.

[0006] However, when the underground coal mine site is at a certain height from the ground, how to transfer a certain weight of the detection vehicle from the ground to the underground coal mine site is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0007] The purpose of this utility model is to solve the above-mentioned technical problems existing in the prior art and to provide a detection vehicle that can be hoisted from the ground to an underground coal mine site to avoid it falling during the transfer and causing structural damage, thereby ensuring that it can work normally and facilitating subsequent operators to enter the scene for rescue work.

[0008] In order to solve the above technical problems, the present invention adopts the following technical solutions:

The vehicle body is characterized by further comprising a bracket and a lifting member, wherein the bracket is a steel structure, the vehicle body is provided with a mounting portion, the bracket is fixed to the mounting portion, and the lifting member is fixed to the bracket, and the lifting member is provided with a lifting hole for connecting to a rope of a lifting device. The lifting hole can be used to lift the vehicle from the ground to an underground coal mine site, preventing the vehicle from falling during transfer and causing structural damage, ensuring normal operation, and facilitating subsequent operators to enter the site for rescue work.

[0010] Furthermore, the bracket includes a base, a fixing plate and a connecting column. The connecting column passes through a through hole 1 of the fixing plate and is welded to the fixing plate. The connecting column is arranged along the length direction of the detection vehicle body. The fixing plate is welded to the base, and the lifting piece is fixed to the connecting column, so that the bracket has a certain firmness and a certain span, and can be provided with multiple lifting pieces.

[0011] Furthermore, the lifting parts include a lifting plate, lifting holes are provided on the lifting plate, two lifting plates are arranged on the same connecting column, the connecting column passes through the second through hole of the lifting plate and is welded to the lifting plate, and the detection vehicle is lifted and lowered through the four lifting holes to improve the lifting stability.

[0012] Furthermore, a connecting plate is welded between the two hoisting plates on the same connecting column, thereby improving the load-bearing capacity of the hoisting parts and enabling the hoisting of certain important detection vehicles.

[0013] Furthermore, both ends of the fixing plate are bent in an upward arc, and the center point of the lifting hole is located above the base, so that the connection position of the lifting hole and the rope is higher than the base, which is convenient for fixing the rope on the lifting plate.

[0014] Furthermore, the mounting portion is provided with a track, which is arranged along the length direction of the probe vehicle body. The base is slidably connected to the track, so that the bracket can be set above the robotic arm. After the position is adjusted, the bracket can block small stones and coal falling from above, thereby protecting the robotic arm.

[0015] Furthermore, the base is provided with a first groove that matches the track, a mounting hole provided with a mounting bolt, the end of which is positioned at the bottom surface of the track. The track is provided with a third through-hole, through which the mounting bolt passes. The mounting bolt moves along the length of the rover body within the third through-hole. The mounting bolt is threadedly connected to a locking nut that is locked to the base. The base has a long travel distance on the track, ensuring that the entire bracket can be positioned above the robotic arm. The locking nut is adjusted to a position above the base, making it easy to tighten the locking nut.

[0016] Furthermore, the track is provided with a second groove, and the end of the mounting bolt is sunk into the second groove, so as to avoid the end of the mounting bolt and the mounting portion from touching each other, thereby preventing the track from being unable to be installed.

[0017] Furthermore, the rail is fixed in the threaded hole of the mounting portion by means of fixing bolts, making it easy to install and disassemble the entire bracket and rail.

[0018] Furthermore, a reinforcement is provided on the inner side of the wheel to increase the inner strength of the wheel and facilitate the connection between the driving member and the wheel.

DETAILED DESCRIPTION

[0035] like Figures 1 to 11 As shown, a detection vehicle of the present invention is used to detect on-site information of a coal mine site.

[0036] The utility model comprises a probe vehicle body 1. The outer shell of the probe vehicle body 1 is made of high-strength aluminum alloy material, and the surface is treated with a coating to enhance its anti-corrosion and anti-scratch properties.

[0037] This utility model utilizes a robotic arm 2 that is movably mounted on a rover body 1, used to clear obstacles. The rover body 1 is equipped with a drive element 3 and wheels 4, which are driven by the drive element 3. This technical solution is prior art, and reference is made to the utility model patent for a portable multifunctional environmental exploration robot (Grant No. CN211867820U). This utility model will not be further elaborated upon.

[0038] The present invention fixes a steel structure bracket 5 to the mounting portion 23 of the probe vehicle body 1, and a hoisting member 6 is fixed to the bracket 5. A hoisting device, which can be a winch, is installed on the ground. The hoisting member 6 is provided with a lifting hole 10, and the rope of the winch is fixed to the lifting hole 10. The winch controls the winding and unwinding of the rope, and the probe vehicle is hoisted from the ground to the underground coal mine site. When the probe vehicle is in the underground coal mine site, the operator at the coal mine site detaches the rope of the winch from the lifting hole 10. This prevents the probe vehicle from falling during transfer and causing structural damage, ensures its normal operation, and facilitates subsequent operators to enter the site for rescue work.

[0039] The present invention has a specific design for the bracket 5: the bracket 5 includes a base 12, a fixing plate 7 and a connecting column 8. The connecting column 8 passes through a through hole 1 of the fixing plate 7 and is welded to the fixing plate 7. A plurality of fixing plates 7 are arranged in parallel on the connecting column 8. The connecting column 8 is arranged along the length direction b of the probe vehicle body. The fixing plate 7 is welded to the base 12, and the hoisting member 6 is fixed to the connecting column 8. The two ends of the fixing plate 7 are bent in an upward arc, and the center point of the lifting hole 10 is located above the base 12, so that the connection position between the lifting hole 10 and the rope is higher than the base 12, which is convenient for fixing the rope. The bracket 5 of the present invention has a certain firmness and a certain span. It can be provided with multiple hoisting members 6, and some tools for repairing the probe vehicle can be placed on the bracket 5. When the probe vehicle is in an underground coal mine, the probe vehicle can be repaired by tools to ensure the normal operation of the probe vehicle.

[0040] The utility model specifically designs the hoisting member 6: the hoisting member 6 includes a hoisting plate 9, with hoisting holes 10 provided on the hoisting plate 9. Two hoisting plates 9 are provided on the same connecting column 8. The connecting column 8 passes through the through hole 20 of the hoisting plate 9 and is welded to the hoisting plate 9. The probe vehicle is hoisted and lowered through the four hoisting holes 10, thereby improving the hoisting stability. A connecting plate 11 is welded between the two hoisting plates 9 on the same connecting column 8, thereby improving the load-bearing capacity of the hoisting member 6 and enabling the hoisting of certain important probe vehicles.

[0041] The robotic arm 2 of the present invention is a prior art design that utilizes multiple sections to ensure smooth operation of the rover. Therefore, the structural integrity of the robotic arm 2 is crucial. In this design, a track 13 is secured to the threaded holes of the mounting portion 23 via fixing bolts 24. The track 13 extends along the longitudinal direction (b) of the rover. The base 12 is slidably connected to the track 13, allowing the bracket 5 to be positioned above the robotic arm 2. The adjusted bracket 5 protects the robotic arm 2 by blocking small rocks and coal from falling from above.

[0042] The base 12 is provided with a groove 18 that matches the track 13. The base 12 is provided with a mounting hole 19, which is provided with a mounting bolt 14. The end 21 of the mounting bolt 14 is limited to the bottom surface of the track 13. The track 13 is provided with a through hole 3 16, through which the mounting bolt 14 passes. The mounting bolt 14 moves in the through hole 3 16 along the longitudinal direction b of the rover body. The mounting bolt 14 is threadedly connected to the locking nut 15, which is locked to the base 12. The base 12 has a long travel distance on the track 13, ensuring that the entire bracket 5 can be placed above the robotic arm 2. At the same time, the locking nut 15 is adjusted to be above the base 12, making it convenient to tighten the locking nut 15.

[0043] The track 13 is provided with a second groove 17 , which is connected to the third through hole 16 , and the end 21 of the mounting bolt 14 is sunk into the second groove 17 to prevent the end 21 of the mounting bolt 14 from touching the mounting portion 23 and causing the track 13 to be unable to be installed.

[0044] Based on the structure of the above embodiment, the present invention has designed another embodiment: four reinforcement members 22 are welded to the inner side of each wheel 4. This increases the inner strength of the wheel 4, facilitates the connection between the drive unit 3 and the wheel 4, and improves the stability of the rover's movement. The wheel 4 is equipped with a wide tread and deep grooves to improve grip and ensure good maneuverability even in adverse road conditions.

[0045] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications based on the present invention that solve essentially the same technical problems and achieve essentially the same technical effects are included within the scope of protection of the present invention.
