Abstract
Description
Technical Field
[0001] This utility model relates to the field of lifting equipment technology, and in particular to a body-in-white balancing lifting equipment. Background Technology
[0002] Traditionally, lifting of parts is achieved using either movable or fixed hooks. When using movable hooks, operators need to accurately place multiple fixed hooks at the lifting points of the parts, which is difficult and inefficient. When using fixed hooks, operators need to accurately place multiple fixed hooks simultaneously, which can easily lead to collisions with the parts when there is insufficient space, affecting their quality. Utility Model Content
[0003] In view of the above situation, it is necessary to provide a body-in-white balancing hoist to address the problems of difficult part hoisting operations and the high risk of parts collision in existing technologies.
[0004] A body-in-white balancing hoist includes a hoist body, two guide blocks, two movable hooks, a counterweight, a control handle, a linkage assembly, a suspension assembly, and several supporting balance blocks. The bottom of the suspension assembly is connected to the hoist body. The control handle is located on the hoist body. The hoist body is rotatably connected to the linkage assembly. One end of the linkage assembly is movably connected to the control handle. The linkage assembly has two movable hooks for rotating the two movable hooks. The bottom of the hoist body has two guide blocks adjacent to one of the movable hooks. The counterweight is located on one side of the hoist body. The bottom of the hoist body has several supporting balance blocks.
[0005] In this invention, when a part needs to be hoisted, the counterweight ensures that the center of gravity of the hoisting assembly, the hoisting device body, and the part are on the same vertical line. The hoisting device body is moved above the part. As the hoisting device body approaches the part, two guide blocks relatively limit the part, preventing it from rotating horizontally. Then, the control handle is activated, moving the linkage assembly. Under the transmission of the linkage assembly, the two movable hooks connected to it rotate, moving from their open position to their lifting point position, thus suspending the part at the lifting point. Lifting the hoisting assembly further moves the hoisting device body and the part below. Several support balance blocks maintain the part's balance after hoisting. When it is necessary to release the part, simply reverse the control handle to quickly detach the two movable hooks from the lifting point, separating the hoisting device body from the part. Because the two movable hooks can be controlled synchronously via the control handle, a single operator can easily hoist the part without the need for multiple people. Furthermore, since the movement of both movable hooks is controlled by the control handle, the operation is simple, and there is no excessive swaying of the two movable hooks during the hoisting process, thus avoiding the phenomenon of the two movable hooks colliding with parts due to swaying during the hoisting process.
[0006] Furthermore, the linkage assembly includes a movable connecting rod and a rotating shaft mechanism, the movable connecting rod being movably connected to the rotating shaft mechanism, and the rotating shaft mechanism being movably connected to the lifting device body.
[0007] Furthermore, the rotating shaft mechanism includes a first rotating shaft and a second rotating shaft, which are located on opposite sides of the lifting device body and are rotatably connected to the lifting device body. The two ends of the movable connecting rod are respectively connected to the first rotating shaft and the second rotating shaft, and one side of the movable connecting rod is connected to the lifting device body through a fixed rod.
[0008] Furthermore, the control handle is hinged to the movable connecting rod via a triangular connecting bracket, and the control handle and the movable connecting rod are connected to the lifting device body via a fixed seat.
[0009] Furthermore, the first rotating shaft is provided with one of the movable hooks, and the second rotating shaft is provided with another movable hook.
[0010] Furthermore, the movable hook is bow-shaped, and the two movable hooks are arranged back to back, with one of the movable hooks facing the two guide blocks.
[0011] Furthermore, the suspension assembly includes a lifting ring and several chains, with both ends of the chains connected to the lifting ring and the lifting device body, respectively.
[0012] Furthermore, the connection points between the lifting ring and several of the chains, the center of gravity of the lifting device body, and the center of gravity of the parts are located on the same vertical line. Attached Figure Description

[0020] A type of white body balancing hoist, such as Figure 1 As shown, it includes a lifting device body 1, two guide blocks 2, two movable hooks 3, a counterweight block 4, a control handle 5, a connecting rod assembly 6, a hanging assembly 7, and a support balance block 8.
[0021] Specifically, such as Figures 1 to 3 As shown, the bottom of the suspension assembly 7 is connected to the lifting device body 1. The suspension assembly 7 includes a lifting ring 71 and multiple chains 72, with both ends of the multiple chains 72 fixedly connected to the lifting ring 71 and the lifting device body 1, respectively. The lifting ring 71 drives the multiple chains 72, thereby changing the position of the lifting device body 1.
[0022] Specifically, the control handle 5 is mounted on the lifting device body 1 and connected to the lifting device body 1 via a fixed base 11. The lifting device body 1 is rotatably connected to the connecting rod assembly 6, and the control handle 5 is hinged to one end of the movable connecting rod 61 via a triangular connecting bracket 10. By opening or closing the control handle 5, the movable connecting rod 61 is moved relative to the lifting device body 1.
[0023] Specifically, Figure 2 To control the connection state of the movable connecting rod 61, the rotating shaft mechanism 62, and the two movable hooks 3 when the handle 5 is in the closed state, Figure 3 To control the connection state of the movable connecting rod 61, the rotating shaft mechanism 62, and the two movable hooks 3 when the handle 5 is in the open state, the linkage assembly 6 includes a movable connecting rod 61 and a rotating shaft mechanism 62. One end of the movable connecting rod 61 is connected to the lifting device body 1 via a fixed seat 11. The movable connecting rod 61 is rotatably connected to the rotating shaft mechanism 62, and the rotating shaft mechanism 62 is rotatably connected to the lifting device body 1. The rotating shaft mechanism 62 includes a first rotating shaft 621 and a second rotating shaft 622. The first rotating shaft 621 and the second rotating shaft 622 are located on opposite sides of the lifting device body 1 and are rotatably connected to the lifting device body 1. Both ends of the movable connecting rod 61 are fixedly connected to the first rotating shaft 621 and the second rotating shaft 622, respectively. One side of the movable connecting rod 61 is fixedly connected to the lifting device body 1 via a fixed rod 9. By controlling the opening or closing of the handle 5, the movable connecting rod 61 is moved relative to the lifting body 1, which in turn drives the first rotating shaft 621 and the second rotating shaft 622 to rotate relative to the lifting body 1, so that the two movable hooks 3 rotate, thereby changing the lifting point position of the two movable hooks 3 and realizing the lifting or detachment of the parts.
[0024] Specifically, the rotating shaft mechanism 62 is used to drive the rotation of the two movable hooks 3. One movable hook 3 is provided on the first rotating shaft 621, and the other movable hook 3 is provided on the second rotating shaft 622. The movable hooks 3 are bow-shaped, and the two movable hooks 3 are arranged back to back, with one movable hook 3 facing the two guide blocks 2. The parts can be lifted by the movable hooks 3.
[0025] Specifically, the bottom of the lifting device body 1 is provided with two guide blocks 2, which are adjacent to a movable hook 3. The two guide blocks 2 limit the relative positioning of the parts and prevent the parts from rotating in the horizontal direction.
[0026] Specifically, a counterweight 4 is provided on one side of the lifting device body 1. When the body-in-white balancing lifting device lifts a part, the connection point of the lifting ring 71 with the multiple chains 72, the center of gravity of the lifting device body 1, and the center of gravity of the part are all located on the same vertical line. By setting the counterweight 4, the connection point of the lifting ring 71 with the multiple chains 72, the center of gravity of the lifting device body 1, and the center of gravity of the part are all located on the same vertical line, so the lifting device body 1 is in a balanced state whether lifting a part or in an idle state.
[0027] Specifically, the bottom of the lifting device body 1 is equipped with multiple support balance blocks 8. By setting multiple support balance blocks 8, the lifting device body 1 remains in a balanced state after lifting the part.
[0028] In this invention, when a part needs to be hoisted, the counterweight 4 ensures that the center of gravity of the hoisting assembly 7, the hoisting body 1, and the part are on the same vertical line. The hoisting body 1 is moved above the part. As the hoisting body 1 gradually approaches the part, the two guide blocks 2 limit the part to prevent it from rotating horizontally. Then, the control handle 5 is turned, which drives the movable connecting rod 61 to move. Under the transmission action of the movable connecting rod 61, the first rotating shaft 621 and the second rotating shaft 622 connected to the movable connecting rod 61 rotate relative to the hoisting body 1, thereby driving the two movable hooks 3 to rotate. This causes the two movable hooks 3 to move from their original open position to the lifting point position, so that the two movable hooks 3 are hoisted to the lifting point of the part. Then, by lifting the movable lifting ring 71, multiple chains 72 are driven to move the hoisting body 1 and the part below it. Multiple support balance blocks 8 keep the part in a balanced state after it is hoisted. When it is necessary to release the part, simply reverse the control handle 5 to quickly disengage the two movable hooks 3 from the lifting points of the part, thus separating the lifting device body 1 from the part. Since the two movable hooks 3 can be controlled synchronously via the control handle 5, a single operator can easily lift the part without the need for multiple people to cooperate. Furthermore, because the movement of both movable hooks 3 is controlled by the control handle 5, operation is simple, and there is minimal swaying of the two movable hooks 3 during lifting, thus avoiding the phenomenon of the two movable hooks 3 colliding with the part due to swaying during lifting.
