Description

Technical Field

[0001] This utility model relates to the technical field of hoisting equipment, and in particular to a truss hoisting equipment. Background Technology

[0002] In the complex process of opening pit mud, frequent and precise lifting of various equipment is a crucial step to ensure the smooth progress of the operation. Opening pit mud involves the handling of a variety of large and precision equipment, such as specialized excavating machinery for digging pit mud, cleaning devices for cleaning pits, and conveying equipment for transporting pit mud. These devices are not only large in size, but some of them also have intricate internal structures, requiring extremely high stability during the lifting process.

[0003] Traditional hoisting methods reveal numerous shortcomings in this scenario. They typically employ only a single lifting rope for equipment lifting. This single-rope design makes it difficult to precisely align the center of gravity of the equipment being lifted with the lifting point, easily leading to significant tilting during hoisting. Furthermore, the limited availability of a single lifting rope severely restricts the ability to adjust the position of the equipment throughout the lifting process. Operators struggle to make timely and precise adjustments to the equipment's position and orientation based on actual operational needs, making it impossible to accurately control the horizontal state of the goods. This not only significantly increases the risk of equipment damage during hoisting but also greatly increases the potential for safety accidents, such as equipment falling, colliding with surrounding facilities or personnel, severely hindering the smooth progress of the cellar opening operation.

[0004] Therefore, there is an urgent need for an efficient and safe truss hoisting device for the process of opening pit mud. Utility Model Content

[0005] The main objective of this invention is to provide a truss hoisting device that can effectively solve the problems mentioned above.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A truss hoisting device includes a truss, with two electric wheels symmetrically installed on the lower front side of the truss and two directional wheels symmetrically installed on the lower rear side of the truss; guide slides are symmetrically fixedly connected to the upper part of the truss; a driving component is installed on the guide slide; and four lifting components are symmetrically arranged at the bottom of the driving component.

[0008] Preferably, the driving component includes a driven pulley and a driving pulley. The driven pulley is rotatably connected to one side of the top of the truss, and the driving pulley is rotatably connected to the other side of the top of the truss. A drive motor is fixedly connected to the wall of the truss, and the driving pulley is fixedly connected to the rotating end of the drive motor through a coupling.

[0009] Preferably, a belt is mounted on both the driven pulley and the driving pulley, a fixed block is fixedly mounted on the belt, a movable plate is fixedly connected to the bottom of the fixed block, and the movable plate is laterally slidably mounted on two guide rods.

[0010] Preferably, the lifting component includes an electric hoist, on which a wire rope is wound, and at the bottom end of the wire rope a hanging assembly is installed.

[0011] Preferably, the hanging assembly includes a connecting plate, which is fixedly connected to the bottom end of the wire rope. A rotating seat is rotatably connected to the bottom of the connecting plate. A hook is fixedly connected to the lower part of the rotating seat. A rotating shaft is rotatably connected to the hook. An anti-detachment stop bar is fixedly connected to the rotating shaft. The end of the anti-detachment stop bar away from the rotating shaft abuts against the hook wall of the hook.

[0012] Preferably, a spring plate is provided between the hook and the anti-detachment bar, one end of the spring plate is fixedly connected to the bar wall of the anti-detachment bar, and the other end of the spring plate is fixedly connected to the hook wall of the hook.

[0013] Preferably, two guide slide rods are symmetrically arranged.

[0014] Preferably, the upper four corners of the truss are all fixedly connected with reinforcing ribs.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The electric hoists in the four lifting components can be individually controlled to retract and extend the wire rope. Combined with the hanging assembly, the height of the four corners of the lifted equipment can be adjusted to bring the equipment to a horizontal position, which greatly improves the safety during lifting and effectively avoids safety accidents caused by equipment tilting. The anti-derailment bar and spring plate design in the hanging assembly further enhance the safety factor of lifting.

[0017] 2. The drive component uses a drive motor to drive the active pulley, which in turn causes the belt to rotate, causing the fixed block and the moving plate to slide along the guide slide rod, thereby moving the lifting component and realizing the movement of the lifted equipment along the axis of the guide slide rod. This facilitates the position adjustment of the lifted equipment in the scenario of opening the pit mud. Attached Figure Description

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Example 1

[0026] like Figure 1 and Figure 2 As shown, a truss hoisting device includes a truss 1. Two electric wheels 2 are symmetrically installed on the lower front side of the truss 1, and two directional wheels 3 are symmetrically installed on the lower rear side of the truss 1. Guide slide rods 7 are symmetrically fixedly connected to the upper part of the truss 1. A drive component 6 is installed on the guide slide rod 7. A lifting component 4 is installed at the bottom of the drive component 6, and four lifting components 4 are symmetrically arranged.

[0027] Furthermore, the drive component 6 includes a driven pulley 603 and a driving pulley 605. The driven pulley 603 is rotatably connected to one side of the top of the truss 1, and the driving pulley 605 is rotatably connected to the other side of the top of the truss 1. A drive motor 606 is fixedly connected to the wall of the truss 1, and the driving pulley 605 is fixedly connected to the rotating end of the drive motor 606 through a coupling. A belt 602 is driven and sleeved on both the driven pulley 603 and the driving pulley 605. A fixing block 604 is fixedly sleeved on the belt 602. A movable plate 601 is fixedly connected to the bottom of the fixing block 604. The movable plate 601 is laterally slidably sleeved on two guide rods 7.

[0028] Furthermore, both the electric wheel 2 and the drive motor 606 are electrically connected to an external switch via wires, and the external switch is electrically connected to an external power source.

[0029] In the aforementioned truss hoisting equipment, the entire truss hoisting equipment is moved by the rotation driven by the electric wheel 2, which in turn rotates in conjunction with the rotation of the directional wheel 3.

[0030] In the aforementioned truss hoisting equipment, the output shaft of the drive motor 606 rotates to drive the drive pulley 605 to rotate. Since the belt 602 is connected to both the driven pulley 603 and the drive pulley 605, the rotation of the drive pulley 605 drives the belt 602 to rotate, which in turn drives the fixed block 604 to move synchronously. The fixed block 604 drives the moving plate 601 to slide along the guide slide bar 7. By controlling the drive motor 606 to rotate forward or backward, the belt 602 can be rotated forward or backward, thereby driving the moving plate 601 to move closer to or further away from the drive motor 606. The movement of the moving plate 601 drives the lifting component 4 to move. Thus, when the lifting component 4 is lifted by the lifting equipment, the moving plate 601 can drive the lifted equipment to move in a direction parallel to the axis of the guide slide bar 7, thereby realizing the movement of the lifted equipment.

[0031] In the aforementioned truss hoisting equipment, the drive motor 606 is a geared motor, which can more accurately control the speed of the active pulley 605, thereby making the speed of the moving plate 601 driving the hoisting component 4 more stable and controllable. The electric wheel 2 and the drive motor 606 are powered by an external power source, and the operation of the electric wheel 2 and the drive motor 606 is controlled by a switch.

[0032] Furthermore, there are two guide rods 7 arranged symmetrically.

[0033] Furthermore, electric wheel 2 is an electric wheel with a braking function.

[0034] Furthermore, reinforcing ribs 5 are fixedly connected to the four corners of the upper part of truss 1.

[0035] In the aforementioned truss hoisting equipment, two parallel guide rods 7 are used to guide the movement direction of the moving plate 601, thereby ensuring the uniformity of the axial movement trajectory of the moving plate 601.

[0036] In the aforementioned truss hoisting equipment, the electric wheel 2 is equipped with a braking function, which enables the truss hoisting equipment to stop and fix its position more safely during use, thereby improving the safety and controllability of the truss hoisting equipment.

[0037] In the aforementioned truss hoisting equipment, the addition of reinforcing ribs 5 creates a triangular structure at the four upper corners of the truss 1, thereby enhancing the overall stability of the truss 1.

[0038] Example 2

[0039] Based on Example 1, in order to improve the safety of truss hoisting equipment during lifting, refer to... Figure 3 , Figure 4 and Figure 5 The lifting component 4 includes an electric hoist 401, on which a wire rope 402 is wound. A hanging assembly 403 is installed at the bottom of the wire rope 402. The hanging assembly 403 includes a connecting plate 4031, which is fixedly connected to the bottom of the wire rope 402. A rotating seat 4032 is rotatably connected to the bottom of the connecting plate 4031. A hook 4034 is fixedly connected to the lower part of the rotating seat 4032. A rotating shaft 4036 is rotatably connected to the hook 4034. An anti-detachment bar 4035 is fixedly connected to the rotating shaft 4036. The end of the anti-detachment bar 4035 away from the rotating shaft 4036 abuts against the hook wall of the hook 4034.

[0040] Furthermore, a spring plate 4033 is provided between the hook 4034 and the anti-detachment bar 4035. One end of the spring plate 4033 is fixedly connected to the bar wall of the anti-detachment bar 4035, and the other end of the spring plate 4033 is fixedly connected to the hook wall of the hook 4034.

[0041] Furthermore, the electric hoist 401 is electrically connected to an external switch via a wire.

[0042] In the aforementioned truss hoisting equipment, by rotating the rotating seat 4032 to the bottom of the connecting plate 4031, the horizontal direction of the hook 4034 can be adjusted by rotating the hook 4034 in the horizontal direction, and the hook groove of the hook 4034 can be changed in the horizontal direction.

[0043] In the aforementioned truss hoisting equipment, when the hanging ring of the equipment to be suspended is hung in the hook groove of the hook 4034, the hanging ring of the equipment compresses the anti-detachment bar 4035. The spring plate 4033 undergoes elastic deformation after being compressed, and the anti-detachment bar 4035 drives the rotating shaft 4036 to rotate. The end of the anti-detachment bar 4035 away from the rotating shaft 4036 moves downward until the hanging ring of the equipment to be suspended is completely inserted into the hook groove of the hook 4034 and separates from the anti-detachment bar 4035. Then, the elastic potential energy of the spring plate 4033 is released, thereby pushing the anti-detachment bar 4035 to rotate in the opposite direction and reset. The end of the anti-detachment bar 4035 away from the rotating shaft 4036 abuts against the inner wall of the hook groove of the hook 4034 again.

[0044] In the aforementioned truss hoisting equipment, four hoisting components 4 work together. The hanging assembly 403 on each hoisting component 4 lifts the hanging rings at the four corners of the external equipment to be suspended. The extension length of the wire rope 402 is controlled by the winding or releasing of the electric hoist 401. The height of the hook 4034 is adjusted by winding or releasing the wire rope 402. Thus, the height of the four corners of the external equipment to be suspended is adjusted using the four hoisting components 4. The electric hoist 401 in each hoisting component 4 can independently control the winding and releasing of the wire rope 402. In actual hoisting, due to factors such as the shape of the equipment, the distribution of the center of gravity, and the position of the lifting point, the height of the four corners of the equipment is often inconsistent. By controlling the electric hoist 401 of the corresponding hoisting component 4 to wind the wire rope 402, the corner can be raised, achieving precise adjustment of the height of a single corner of the equipment. This can change the horizontal situation of the external equipment to be suspended until the external equipment to be suspended is adjusted to a relatively horizontal state, improving the safety during hoisting.

[0045] In the aforementioned truss hoisting equipment, four electric hoists 401 are controlled to work independently via external switches.
