Description

Technical Field

[0001] This invention relates to the field of rescue and demolition technology, specifically to a mine rescue and demolition device. Background Technology

[0002] Mine rescue demolition equipment refers to specialized equipment used in emergency rescue operations at mines to break through obstacles, open rescue channels, and conduct rescue work. Demolition equipment can quickly break through obstacles in a short time, improving rescue efficiency and shortening the rescue time for trapped personnel. Different types of demolition equipment, such as manual, electric, and hydraulic, can be selected based on the actual conditions at the rescue site. Common demolition equipment includes hydraulic breakers, cutting machines, chainsaws, spreaders and shears, drilling rigs, and other instruments. During mine rescue operations, rescuers must ensure the safety of trapped personnel while also preventing secondary mine collapses that could injure them.

[0003] Hydraulic spreaders are frequently used in mine rescue operations. A common tool in emergency rescue and industrial production, hydraulic spreaders operate primarily on hydraulic principles, possessing powerful expansion, tearing, and pulling capabilities. In emergencies, they can quickly break through rubble, collapsed buildings, or other obstacles, creating safe passages for rescuers and effectively shortening rescue time. Furthermore, their expansion and pulling functions can move and lift heavy obstacles, such as collapsed beams and walls, allowing rescuers to more easily access trapped individuals. Additionally, the powerful hydraulic spreaders... Spreading shears can tear and cut metal structures, such as steel bars and iron plates, to further break up obstacles and improve rescue efficiency. When using hydraulic spreaders to lift objects such as rocks and beams, workers need to find points to support the hydraulic spreaders to ensure that the lifting work can be carried out stably. However, in actual rescue work, due to the large amount of debris generated by mine collapses, rescue work is often carried out in uneven piles of rocks. As a result, workers need to spend a certain amount of time finding points to support the hydraulic spreaders, which affects rescue efficiency. Therefore, we propose a mine rescue demolition device. Summary of the Invention

[0004] The purpose of this invention is to provide a mine rescue demolition device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a mine rescue demolition device, comprising a clamp body and a power device connected to the clamp body, an annular sleeve fixedly installed on the power device, a support shaft symmetrically fixedly installed on the annular sleeve, and a hinge rod 1 rotatably connected to the support shaft, and a hinge rod 2 rotatably connected to the end of the hinge rod 1, and a fixing sleeve fixedly installed on the hinge rod 2;

[0006] The fixed sleeve has an annular panel inside, and a connecting rod frame is fixedly installed on the annular panel. A drive motor is fixedly installed at the end of the connecting rod frame. The output end of the drive motor is used to install a drill bit for drilling holes in the ore. The annular panel is also provided with a telescopic mechanism, which enters the hole to provide support. An installation panel is fixedly installed on the inner top wall of the fixed sleeve. Electromagnetic mechanism A and electromagnetic mechanism B are installed in parallel on the installation panel. A magnetic shaft is fixedly installed on the annular panel, and the magnetic shaft is located directly below electromagnetic mechanism A. When electromagnetic mechanism A is energized, it generates a repulsive force on the magnetic shaft.

[0007] Preferably, the outer wall of the annular panel is equipped with a rotating panel that is rotatably connected to it, and the outer wall of the rotating panel is covered with a silicone layer. Multiple constant force springs are connected between the rotating panel and the inner wall of the fixed sleeve.

[0008] Preferably, a sliding shaft is fixedly installed on the outer wall of the annular panel, and a limiting groove is provided on the inner wall of the fixed sleeve, wherein the sliding shaft slides within the limiting groove, and there is an angle difference between the telescopic mechanism and the connecting rod frame.

[0009] Preferably, the limiting groove includes a straight travel area, a spiral area connected to the straight travel area, and a sliding area connected to the other end of the spiral area.

[0010] Preferably, the telescopic mechanism includes a limiting sleeve disposed on and slidably connected to the annular panel, and the limiting sleeve is rotatably connected to the inner wall of the fixed sleeve. An iron shaft is installed inside the limiting sleeve, and one end of the iron shaft is located directly below the electromagnetic mechanism B. When the electromagnetic mechanism B is energized, it generates a repulsive force on the iron shaft. A support panel is fixedly installed on the outer wall of the iron shaft, and a return spring is connected between the support panel and the inner bottom wall of the limiting sleeve, and the return spring is sleeved on the iron shaft.

[0011] Preferably, a rotating sleeve is installed on the outer wall of the iron shaft and is rotatably connected to it. The rotating sleeve is located inside the limiting sleeve. An annular shaft is symmetrically installed on the rotating sleeve. A snap-fit ​​groove is symmetrically provided on the limiting sleeve. The annular shaft is limited to sliding within the snap-fit ​​groove. A torsion spring is connected between the rotating sleeve and the support panel.

[0012] Preferably, the snap-fit ​​groove includes a lifting area, an angle adjustment area communicating with the lifting area, and an L-shaped area communicating with the angle adjustment area. A touch shaft is also fixedly installed on the annular panel, and the touch shaft is located between the magnetic shaft and the limiting sleeve. A sensing element is fixedly installed on the mounting panel, and the sensing element is located on the movement trajectory of the touch shaft.

[0013] Preferably, a rubber sleeve is fitted onto one end of the iron shaft, and the end of the rubber sleeve is curved inward in an arc shape.

[0014] Preferably, the surface roughness of the middle region of the fixed sleeve is greater than that of the two ends.

A square panel is fixedly mounted at the end of the rotating rod, and multiple protrusions are fixedly mounted on the square panel.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. This invention utilizes a drive motor to create holes on the surface of the ore, allowing a telescopic mechanism to enter the hole for support. An electromagnetic mechanism A generates a repulsive force on the magnetic shaft, causing the annular panel to descend. Under the action of the sliding shaft and the limiting groove, the positions of the drive motor and the telescopic mechanism are switched, allowing the telescopic mechanism to enter the hole after the hole is created. This prevents the clamp from becoming unstable during the lifting process. Furthermore, the structural design of this invention can effectively improve the support point finding speed.

[0018] 2. This invention, by rotating the annular shaft on the sleeve and the locking groove, enables the iron shaft to self-lock during the process of entering the hole, preventing the iron shaft from returning to its initial position under the action of the return spring due to a sudden power failure of the electromagnetic mechanism B, thereby improving the safety of the clamp body during operation and reducing the probability of safety accidents.

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figure 1-11 This invention provides a technical solution: a mine rescue demolition device. This invention addresses the technical problems in the background art by making corresponding improvements. It includes a clamp body 1 and a power device 2 connected to the clamp body 1, and an annular sleeve 3 fixedly installed on the power device 2. The annular sleeve 3 and the power device 2 can be connected by bolts. Therefore, when it is necessary to remove the annular sleeve 3, the bolts connecting them can be removed, and then the annular sleeve 3 can be removed from the power device 2. Support shafts 31 are symmetrically fixedly installed on the annular sleeve 3. A hinge rod 32 is mounted on the upper part of the sleeve and rotatably connected thereto. A second hinge rod 33 is mounted on the end of the first hinge rod 32 and rotatably connected thereto. A fixed sleeve 4 is fixedly mounted on the second hinge rod 33. Multiple rubber pads are installed on the inner wall of the annular sleeve 3 to provide cushioning. A rotating panel 412 is mounted on the fixed sleeve 4, and the outer wall of the rotating panel 412 is covered with a silicone layer 413. Multiple constant force springs 45 connect the rotating panel 412 and the inner wall of the fixed sleeve 4. The surface roughness of the middle region of the fixed sleeve 4 is greater than that of the two ends (as shown in the attached figure). Figure 11As shown, the fixed sleeve 4 has an annular panel 41 inside, which is located inside and rotatably connected to the rotating panel 412. A connecting rod bracket 42 is fixedly installed on the annular panel 41, and a drive motor 43 is fixedly installed at the end of the connecting rod bracket 42. The output end of the drive motor 43 is used to install a drill bit for drilling holes in the ore. Since the drill bit is a prior art mechanism, it is not described in detail in this invention. A telescopic mechanism 5 is also provided on the annular panel 41, which enters the hole to provide support. An installation panel 44 is fixedly installed on the inner top wall of the fixed sleeve 4. An electromagnetic mechanism A441 and an electromagnetic mechanism B442 are installed in parallel on the installation panel 44. An annular panel 41 is fixedly installed with... A magnetic shaft 411 is located directly below an electromagnetic mechanism A441. When the electromagnetic mechanism A441 is energized, it generates a repulsive force on the magnetic shaft 411. A sliding shaft 414 is fixedly installed on the outer wall of the annular panel 41, and a limiting groove 46 is provided on the inner wall of the fixed sleeve 4. The sliding shaft 414 slides within the limiting groove 46. The limiting groove 46 includes a straight section 461, a spiral section 462 connected to the straight section 461, and a sliding section 463 connected to the other end of the spiral section 462. In the initial state, the sliding shaft 414 is located at the initial end of the straight section 461, that is, the electromagnetic mechanism A441 is not energized at this time, and the rotating panel 412 and the annular panel 41 are at their highest points.

[0033] Step a: In the specific rescue operation, assuming the rescue environment is relatively complex and the site is on a collapsed ore layer, if clamp 1 is used to lift the ore, the annular sleeve 3 can be fixed to the power equipment 2 with bolts first. The position of the fixed sleeve 4 can be adjusted by adjusting hinge rod 1 32 and hinge rod 2 33. Then, observe the position of the telescopic mechanism 5 to see if it is nearly perpendicular to the ore surface. If the position is good, then fix the drill bit on the output end of the drive motor 43, start the drive motor 43 and energize the electromagnetic mechanism A441. The electromagnetic mechanism A441 will then move to the annular surface... The magnetic shaft 411 on plate 41 generates a repulsive force, causing the annular panel 41 to descend. The connecting rod 42 and drive motor 43 mounted on the annular panel 41 descend synchronously. It should be noted that the telescopic mechanism 5 and the annular panel 41 are slidably connected. Therefore, when the annular panel 41 descends, the telescopic mechanism 5 is stationary. During the descent, the sliding shaft 414 on the outer wall of the annular panel 41 descends along the straight section 461, moves into the spiral section 462, and finally enters the sliding section 463. Figure 6As shown, when the sliding shaft 414 enters the spiral region 462, the annular panel 41 adjusts its angle accordingly. Since the telescopic mechanism 5 and the annular panel 41 are slidably connected, when the annular panel 41 adjusts its angle, the positions of the telescopic mechanism 5 and the connecting rod 42 are reversed. At this time, the output end of the drive motor 43 is located at the original position of the telescopic mechanism 5. When the sliding shaft 414 enters the sliding region 463, the drill bit on the output end of the drive motor 43 approaches the surface of the ore, and at this time, the silicone layer 413 on the surface of the rotating panel 412 also enters the position where the surface roughness of the inner wall of the fixed sleeve 4 is relatively large. The specific design reason is: when the drill bit approaches the ore... When the surface is touched, a certain impact force is generated, which can easily damage the surface of the drill bit. By increasing the friction of the inner wall of the fixed sleeve 4, the descent speed of the rotating panel 412 is reduced, and the drill bit slows down when it approaches the surface of the ore. Then, the drill bit performs hole-making work on the ore under the action of the drive motor 43. After the hole is opened, the electromagnetic mechanism A441 is de-energized, and the rotating panel 412 is reset under the action of the constant force spring 45. Then, the sliding shaft 414 passes through the sliding area 463, the spiral area 462 and the straight area 461, so that the telescopic mechanism 5 returns to the initial position. At this time, the telescopic mechanism 5 is inserted into the hole, which can play a fixing role.

[0034] As a further limitation of the present invention, the telescopic mechanism 5 includes a limiting sleeve 51 disposed on the annular panel 41 and slidably connected to the annular panel 41, and the limiting sleeve 51 is rotatably connected to the inner wall of the fixed sleeve 4. As described above, when the annular panel 41 descends, since the limiting sleeve 51 is slidably connected to the annular panel 41 and the limiting sleeve 51 is limited by the fixed sleeve 4, the limiting sleeve 51 will be stationary when the annular panel 41 descends. An iron shaft 52 is installed inside the limiting sleeve 51, and one end of the iron shaft 52 is located directly below the electromagnetic mechanism B442. When the electromagnetic mechanism B442 is energized, it generates a repulsive force on the iron shaft 52. A support panel 53 is fixedly installed on the outer wall of the iron shaft 52, and a return spring 54 is connected between the support panel 53 and the inner bottom wall of the limiting sleeve 51. The return spring 54 is sleeved on the iron shaft 52, and a joint is installed on the outer wall of the iron shaft 52. A rotating sleeve 521 is rotatably connected and located inside a limiting sleeve 51. An annular shaft 522 is symmetrically mounted on the rotating sleeve 521. A snap-fit ​​groove 55 is symmetrically arranged on the limiting sleeve 51. The annular shaft 522 is limited and slidable within the snap-fit ​​groove 55. As a further limitation in this invention, the snap-fit ​​groove 55 includes a lifting area 551, an angle adjustment area 552 connected to the lifting area 551, and an L-shaped area 553 connected to the angle adjustment area 552. A torsion spring 56 is connected between the rotating sleeve 521 and the support panel 53. A touch shaft 47 is also fixedly mounted on the annular panel 41 and is located between the magnetic shaft 411 and the limiting sleeve 51. A sensing element 443 is fixedly mounted on the mounting panel 44 and is located on the movement trajectory of the touch shaft 47. The sensing element 443 is used to switch the energization status of the electromagnetic mechanism A441 and the electromagnetic mechanism B442.

[0035] Step b: In conjunction with step a, when the electromagnetic mechanism A441 is de-energized, the rotating panel 412, under the action of multiple constant force springs 45, drives the annular panel 41 to rise. After the annular panel 41 rises to its initial state, the contact shaft 47 on the annular panel 41 will touch the sensing element 443. The sensing element 443 controls the electromagnetic mechanism B442 to be energized. Since the telescopic mechanism 5 returns to its initial position at this time, and the drill bit, under the action of the drive motor 43, performs drilling work on the ore located below the telescopic mechanism 5, when the electromagnetic mechanism B442 is energized, the electric... The magnetic mechanism B442 generates a repulsive force on the end of the iron shaft 52, causing the iron shaft 52 to descend. During the descent, the rotating sleeve 521 on the iron shaft 52 moves synchronously with it, and the annular shaft 522 on the outer wall of the rotating sleeve 521 moves along the trajectory of the lifting area 551 and into the angle adjustment area 552. At this time, the rotating sleeve 521 adjusts its angle, and the iron shaft 52 continues to move. The annular shaft 522 on the outer wall of the rotating sleeve 521 then moves to the end of the L-shaped area 553 under the action of the torsion spring 56. Figure 9 As shown, when the annular shaft 522 moves to the end of the L-shaped region 553, the iron shaft 52 enters the bottom of the drilled hole. Even if the electromagnetic mechanism B442 is de-energized, the iron shaft 52 cannot move in the reverse direction. Specifically, the annular shaft 522 is obstructed by the inner wall of the L-shaped region 553. Figure 3 As shown, the annular sleeve 3 has an opening, which is used to facilitate the operator to apply force to the annular shaft 522, so that the annular shaft 522 leaves from the end of the L-shaped area 553 and enters the angle adjustment area 552. Then, under the action of the return spring 54 and the torsion spring 56, the iron shaft 52 performs a reset movement. Through this design, the iron shaft 52 is always fixed in the hole opened by the drill bit. Under the action of the electromagnetic mechanism B442 and the L-shaped area 553, the iron shaft 52 can be kept fixed in the hole, which can limit the annular sleeve 3 and effectively prevent the clamp 1 from becoming unstable during the lifting operation.

[0036] Multiple rubber pads are installed on the inner wall of the annular sleeve 3 to absorb the vibration generated by the drill bit during drilling, thus preventing it from affecting the lifting operation of the clamp body 1. During drilling, some gravel may fall into the hole. Therefore, a rubber sleeve 523 is fitted onto one end of the iron shaft 52, with the end of the rubber sleeve 523 curved inwards in an arc shape. When the iron shaft 52 enters the hole, the rubber sleeve 523 first contacts the bottom of the hole. As the iron shaft 52 continues to move, the end of the rubber sleeve 523 continues to curve inwards, pushing the ore into the center and preventing it from affecting the supporting effect of the iron shaft 52. Furthermore, during rescue operations in rainy seasons, the lifting position of the clamp body 1 may be located in areas of relatively loose soil. In such cases, if... If drilling is not possible, it cannot provide effective support. Therefore, the present invention has symmetrically distributed fixed shafts 48 fixedly installed on the outer wall of the fixed sleeve 4, and a rotating rod 49 is installed on the fixed shaft 48. A square panel 40 is fixedly installed at the end of the rotating rod 49, and multiple protrusions 401 are fixedly installed on the square panel 40. In the case of soft soil, the rotating rod 49 can be rotated to make the square panel 40 contact the soil layer. It should be noted that the rotating rod 49 is a telescopic shaft. When the square panel 40 contacts the soil layer, the rotating rod 49 is pulled to apply pressure to the soil layer. The multiple protrusions 401 sink into the soil layer to increase the contact area with the soil layer, ensuring that the clamp 1 is stable in the soft soil environment and avoiding the clamp 1 from becoming unstable.
