Description

Technical Field

[0001] The invention belongs to the technical field of mine hoisting equipment, and in particular relates to a hoisting mechanism used in mines. Background Art

[0002] In special environments such as mines, traditional lifting mechanisms usually use wire ropes, pulley blocks and manual operations to operate. However, these traditional methods have the following shortcomings: first, the lifting efficiency is low and cannot meet the needs of efficient production in mines; second, safety accidents are prone to occur during operation, such as wire rope breakage, hoisted objects slipping, etc.; finally, traditional lifting mechanisms have high technical requirements for operators and are difficult to achieve automation and intelligence.

[0003] In view of the above-mentioned problems, Chinese patent CN215854718U proposes a hoisting mechanism for mining electromechanical equipment. When people use the mining electromechanical equipment hoisting mechanism, the hoisting machine moves to the mining electromechanical equipment, and then four hooks and clamps connected by four chains are placed on both sides of the electromechanical equipment respectively, which can evenly bear the force and improve stability. The hook is placed under the mining electromechanical equipment, and then the clamp inside the hook is placed on the electromechanical equipment on the mine. The teeth of the hook are facing the mining electromechanical equipment above. The compression of the hook and the clamp is adjusted by the built-in spring to improve the bite force and prevent it from falling easily. Then turn on the switch controller, and the current is transmitted to the motor through the cable, so that the motor starts to operate, which embodies semi-automation, improves work efficiency, and improves the installation and movement of electromechanical equipment.

[0004] The above scheme improves the installation and movement of electromechanical equipment, but in actual use, it is found that when the equipment needs to pause or change direction during movement, the electromechanical equipment itself may produce a certain amount of shaking due to inertia, thereby affecting the stability of the main chain, which may not only cause damage to the equipment, but also pose a threat to the safety of the operator.

In the above technical solution, further, a symmetrically arranged flip plate is provided on the outer wall of the gathering frame, and a pair of distant support plates are fixedly connected to the flip plate on the side away from the gathering frame, and a guide shaft is rotatably connected between two adjacent support plates, and the fourth pull rope for fixing the hoisted object forms a side V structure through the guide shaft when it is tightened. In the above technical solution, further, the gathering frame is fixedly connected with a symmetrically arranged fixed axis, and the fixed axis is rotatably connected and penetrates the flip plate, the second mounting frame is fixedly connected to the bottom of the first mounting frame, a dual-axis motor is fixedly installed on the central axis of the inner side wall of the second mounting frame, and a rotating axis is fixedly connected to the driving end of the dual-axis motor, a pair of second wire-releasing mechanisms separated from each other are fixedly installed on the inner side of the second mounting frame, and the rotating axis is inserted into the second wire-releasing mechanism, a second through hole is opened at the bottom of the second mounting frame, and a third pull rope extending downward is wound in the second wire-releasing mechanism, the third pull rope penetrates the second through hole and extends to the bottom of the second through hole, and the second through hole is fixedly connected to the flip plate through a connecting ear.

After that, the fourth pull rope is successively guided by the guide wheel and the guide shaft, and can form a coherent pulling force when tightened, and can prevent it from shaking. Therefore, after the second clamp fixes the hoisted object, the fourth pull rope is driven by the first wire-releasing mechanism to extend back into the first wire-releasing mechanism, and the hoisted object can be hoisted together with the second pull rope. Because the fourth pull rope and the second pull rope belong to two different driving sources, and the fourth pull rope has good stability, it reduces the load of the first pull rope and the second pull rope, and also simultaneously maintains the stability of the hoisting process of the hoisted object; Through the connection between the rotating shaft and the second wire-releasing mechanism, the dual-axis motor can drive the third pull rope to extend or extend back into the second wire-releasing mechanism. Since the flip plate is rotatable, it can drive the flip plate to flip along the fixed axis, thereby adjusting the lateral distance between the guide shaft and the suspended object, thereby changing the angle formed when the fourth pull rope is tightened, and thus can adapt to irregular suspended objects, with good versatility.

DETAILED DESCRIPTION In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0013] like Figure 1-Figure 7A lifting mechanism for a mine shown in the figure comprises a support frame 1, a driving machine base 2 is slidably mounted on the support frame 1, a lifting mechanism 3 is arranged inside the driving machine base 2, the lifting mechanism 3 comprises a hoisting mechanism installed inside the driving machine base 2, a first pull rope 7 extends downward from the inside of the hoisting mechanism, a connecting block 6 is fixedly connected to the end of the first pull rope 7, a plurality of second pull ropes 9 are fixedly connected to the bottom of the connecting block 6, a first clamp 10 is fixedly connected to the end of the second pull rope 9, a stabilizing component is arranged outside the support frame 1, the stabilizing component is used to reduce the shaking degree of the first pull rope 7, the stabilizing component comprises a sliding plate 4 slidably connected to the bottom of the support frame 1, a symmetrically arranged connecting frame 20 is fixedly connected between the sliding plate 4 and the driving machine base 2, a gathering frame 13 is fixedly connected to the bottom of the sliding plate 4, a connecting plate 21 is fixedly connected to the bottom of the gathering frame 13, a fixing cylinder 5 is fixedly connected between the connecting plate 21 and the sliding plate 4, the first pull rope 7 is slidably connected and penetrates The first pull rope 7 is fixed to the bottom of the fixed cylinder 5. In the above arrangement, the sliding plate 4 and the connecting plate 21 are connected as a whole through the connecting frame 20 to improve the overall structural strength, and the structural strength of the fixed cylinder 5 arranged therebetween is correspondingly improved, and thereby the first pull rope 7 inserted under the fixed cylinder 5 is supported and limited, and the degree of shaking is reduced. When the driving base 2 moves in parallel, the sliding plate 4 is synchronously driven to slide on the bottom of the support frame 1 by the connection of the connecting frame 20, so that the fixed cylinder 5 maintains support and limitation for the first pull rope 7. Since the part of the first pull rope 7 received in the fixed cylinder 5 will not shake, in actual use, the hoisted object is uniformly hoisted to a certain height, so that the first pull rope 7 is received inside the fixed cylinder 5, thereby avoiding the shaking of the first pull rope 7, and correspondingly avoiding the problem that the driving base 2 will drive the first pull rope 7 to shake when moving or stopping the hoisted object.

[0014] A balancing assembly is provided at the bottom of the driving machine base 2, and the balancing assembly is used to keep the hoisted object balanced. The balancing assembly includes a first mounting frame 11 fixedly connected to both sides of the driving machine base 2, a first through-hole 28 is provided at the bottom of the first mounting frame 11, a first wire-releasing mechanism 22 is fixedly installed inside the first mounting frame 11, a fourth pull rope 17 extending downward is wound inside the first wire-releasing mechanism 22, and the fourth pull rope 17 passes through the first through-hole 28 and extends to the bottom of the first through-hole 28, a second clamp 18 is fixedly connected to the end of the fourth pull rope 17, a pair of mounting plates 24 are fixedly connected to one side of the second mounting frame 12, a guide wheel 23 is rotatably installed between the pair of mounting plates 24, a symmetrically arranged flip plate 14 is provided on the outer wall of the gathering frame 13, a pair of distant support plates 15 are fixedly connected to the flip plate 14 away from the gathering frame 13, and a pair of adjacent support plates 15 are rotatably connected between the two support plates 15. The guide shaft 30 and the fourth pull rope 17 for fixing the hoisted object form a side V structure through the guide shaft 30 when being tightened. In the above setting, the end of the flip plate 14 is away from the driving machine base 2, and the guide shaft 30 fixed thereon is also correspondingly at a certain distance from the hoisted object. Thereafter, the fourth pull rope 17 is successively guided by the guide wheel 23 and the guide shaft 30, and can form a continuous pulling force when tightened, and can prevent it from shaking. Therefore, after the second clamp 18 fixes the hoisted object, the fourth pull rope 17 is driven by the first wire-releasing mechanism 22 to extend back into the first wire-releasing mechanism 22, and can lift the hoisted object together with the second pull rope 9. Because the fourth pull rope 17 and the second pull rope 9 belong to two different driving sources, and the fourth pull rope 17 has good stability, it reduces the load of the first pull rope 7 and the second pull rope 9 while simultaneously maintaining the stability of the hoisting process of the hoisted object.

[0015] A symmetrically arranged fixed shaft 19 is fixedly connected to the gathering frame 13, and the fixed shaft 19 is rotatably connected and penetrates the inserted flip plate 14, a second mounting frame 12 is fixedly connected to the bottom of the first mounting frame 11, a double-axis motor 25 is fixedly installed on the central axis of the inner wall of the second mounting frame 12, a rotating shaft 26 is fixedly connected to the driving end of the double-axis motor 25, a pair of second wire-releasing mechanisms 27 separated from each other are fixedly installed on the inner side of the second mounting frame 12, and the rotating shaft 26 is inserted into the second wire-releasing mechanism 27, a second through hole 29 is opened at the bottom of the second mounting frame 12, a third pull rope 16 extending downward is wound in the second wire-releasing mechanism 27, and the third pull rope 16 passes through the second through hole 29 and extends to the bottom of the second through hole 29, and the second through hole 29 is fixedly connected to the flip plate 14 through a connecting ear. In the above setting, through the connection between the rotating shaft 26 and the second wire-releasing mechanism 27, the dual-axis motor 25 can drive the third pull rope 16 to extend or extend back into the second wire-releasing mechanism 27. Since the flip plate 14 is rotatably arranged, the flip plate 14 can be driven to flip along the fixed axis 19, thereby adjusting the lateral distance between the guide shaft 30 and the suspended object, thereby changing the angle formed when the fourth pull rope 17 is tightened, and then it can adapt to irregular suspended objects, and has good versatility.

[0016] The first pull rope 7 is fixedly connected to a stabilizing plate 8, and counterweights are symmetrically fixed on the stabilizing plate 8. The arrangement direction of the symmetrically arranged counterweights is consistent with the sliding direction of the driving base 2. This design can improve the balance of the first pull rope 7 and prevent it from shaking. When the driving base 2 moves in parallel, the counterweights in the same direction are driven synchronously, and the same radial force can effectively prevent the first pull rope 7 from twisting itself.

[0017] Working principle: The sliding plate 4 and the connecting plate 21 are connected as a whole by the connecting frame 20, so as to improve the overall structural strength, and correspondingly improve the structural strength of the fixed cylinder 5 arranged therebetween, and thereby support and limit the first pull rope 7 inserted under the fixed cylinder 5, and reduce its shaking degree. When the driving base 2 moves in parallel, the sliding plate 4 is synchronously driven to slide on the bottom of the support frame 1 by the connection of the connecting frame 20, so that the fixed cylinder 5 maintains the support and limit of the first pull rope 7. Since the part of the first pull rope 7 stored in the fixed cylinder 5 will not shake, in actual use, the hoisted object is uniformly hoisted to a certain height, so that the first pull rope 7 is stored in the fixed cylinder 5, thereby avoiding the shaking of the first pull rope 7, and correspondingly avoiding the problem that the driving base 2 will drive the first pull rope 7 to shake when the hoisted object moves or stops; The end of the flip plate 14 is away from the driving machine base 2, and the guide shaft 30 fixed thereon is also correspondingly at a certain distance from the hoisted object. After that, the fourth pull rope 17 is successively guided by the guide wheel 23 and the guide shaft 30, and can form a coherent tension when tightened, and can prevent it from shaking. Therefore, after the second clamp 18 fixes the hoisted object, the fourth pull rope 17 is driven by the first wire-releasing mechanism 22 to extend back into the first wire-releasing mechanism 22, and can be hoisted together with the second pull rope 9. Because the fourth pull rope 17 and the second pull rope 9 belong to two different driving sources, and the fourth pull rope 17 has good stability, it reduces the load of the first pull rope 7 and the second pull rope 9, and also simultaneously maintains the stability of the hoisting process of the hoisted object; Through the connection between the rotating shaft 26 and the second wire-releasing mechanism 27, the dual-axis motor 25 can drive the third pull rope 16 to extend or extend back into the second wire-releasing mechanism 27. Since the flip plate 14 is rotatably arranged, the flip plate 14 can be driven to flip along the fixed axis 19, thereby adjusting the lateral distance between the guide shaft 30 and the suspended object, thereby changing the angle formed when the fourth pull rope 17 is tightened, and thus can adapt to irregular suspended objects, with good versatility.
