Description

Technical Field

[0001] This utility model relates to the field of building hoisting equipment technology, specifically a block hoisting device. Background Technology

[0002] Block hoisting refers to the process in building construction of using cranes or other hoisting equipment to lift pre-made blocks from the ground to a designated height and precisely place them onto a wall or structure. This operation typically requires strict safety measures and precise operation to ensure the blocks are securely positioned while protecting the safety of construction workers.

[0003] However, in traditional block hoisting operations, the crane hook is directly attached to the block, or a hoisting frame with an open top is used. Due to the uneven surface of the block stack or swaying during the hoisting process, the blocks are prone to slipping, affecting work efficiency and safety. In addition, manual hoisting and bottom sealing operations are complex and inefficient.

[0004] Therefore, we propose a block hoisting device to solve the problems mentioned above. Utility Model Content

[0005] This utility model provides a block hoisting device, which can solve the problem that traditional hoisting tools in existing block hoisting equipment are prone to causing blocks to slip, affecting work efficiency and safety.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A block hoisting device includes a lifting mechanism. The lower end of the lifting mechanism is connected to an extraction mechanism for loading blocks. The extraction mechanism includes a lifting box for covering the loaded blocks. The bottom of the lifting box is open and equipped with a retractable closure component. Clamping plates are respectively provided on both sides of the inside of the lifting box. An electric push rod is installed on the box wall of the lifting box near the clamping plates. The ends of the two clamping plates that are close to each other are chamfered.

[0008] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0009] This invention utilizes a lifting mechanism to enclose the entire block stack in a lifting box. The bottom opening of the lifting box facilitates contact with the block stack. The clamping plates on both sides are driven by electric push rods to move in opposite directions. The chamfered structure on the clamping plates forms a guide slope during clamping, automatically correcting block position deviations and ensuring stable clamping. Then, the bottom opening of the lifting box is closed by a retractable sealing component, forming a completely enclosed clamping space to prevent blocks from slipping during lifting. Next, the adjustment component at the top of the lifting mechanism drives a high-strength guide plate vertically via a telescopic cylinder, raising the clamping plates and ensuring the blocks are completely off the ground. The sliding connection design of the electric push rods allows the clamping plates to move horizontally and vertically. The sliding seat inside the crossbeam frame is driven by a stepper motor for precise X-axis positioning. The symmetrical steel wire ropes of the dual-shaft winch form stable lifting points via a triangular hanger. Synchronous winding and unwinding of the dual shafts ensures the lifting box moves vertically without tilting, accurately covering any position in the stockpile. Ultimately, through this three-dimensional moving system, the device can achieve automatic hoisting, sealing, and precise positioning of blocks, ensuring unmanned continuous operation, improving hoisting efficiency and safety, effectively solving the risk of slippage caused by uneven block surfaces in traditional hoisting equipment, and is easy to operate and has low maintenance costs.

[0015] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0016] Example 1:

[0017] Please see Figure 1-4This utility model provides a technical solution:

[0018] A block hoisting device includes a lifting mechanism 1. The lower end of the lifting mechanism 1 is connected to an extraction mechanism 2 for loading blocks. The extraction mechanism 2 includes a lifting box 201 for covering the loaded blocks. The bottom of the lifting box 201 is open and equipped with a retractable closure component. Clamping plates 204 are respectively provided on both sides of the interior of the lifting box 201. An electric push rod 205 is installed on the box wall of the lifting box 201 near the clamping plates 204. The ends of the two clamping plates 204 that are close to each other are provided with chamfers.

[0019] In the above scheme, the lifting mechanism 1 encloses the entire block assembly via the lifting box 201, and the bottom opening design facilitates contact with the block stack. The two side clamping plates 204 are driven to move in opposite directions by electric push rods 205. The chamfered structure forms a guide slope during clamping, automatically correcting block position deviations. After the clamping plates 204 stably clamp the block stack, the door panel 209 is closed to form a closed clamping space, avoiding the risk of slippage caused by uneven block surfaces in traditional lifting equipment. The retractable enclosed component acts as a bottom safety barrier to prevent debris from falling during lifting.

[0020] The front of the lifting box 201 has multiple windows for easy observation, and the windows are sealed with high-strength tempered glass.

[0021] Furthermore, an adjustment assembly for adjusting the position of the clamping plate 204 is installed on the top of the lifting box 201, and an electric push rod 205 is slidably connected to the box wall of the lifting box 201. The adjustment assembly includes a telescopic cylinder 207, which is fixedly connected to the top wall of the lifting box 201. A high-strength guide plate 206 is fixedly connected to the working end of the telescopic cylinder 207, and the high-strength guide plate 206 is slidably connected to the inside of the lifting box 201. An opening matching the shape of the high-strength guide plate 206 is opened at one end of the clamping plate 204 near the top of the lifting box 201, and the end of the high-strength guide plate 206 passes through the openings of the two clamping plates 204.

[0022] In the above scheme, the adjustment component uses a telescopic cylinder 207 to drive the high-strength guide plate 206 to move vertically. When the guide plate rises, its sliding engagement with the opening of the clamping plate 204 forces the clamping plate 204 to rise synchronously, so that the clamped block is completely lifted off the ground. The electric push rod 205 adopts a sliding connection design, allowing the clamping plate 204 to move in both horizontal clamping and vertical lifting dimensions. This structure solves the problem of friction loss between the clamp and the ground when lifting with traditional grippers, and also facilitates the closing of the door panel 209.

[0023] Furthermore, the retractable enclosure includes a door panel 209 and a guide groove 208. The guide groove 208 is located at the bottom of the lifting box 201 near the opening, and the door panel 209 is slidably connected inside the guide groove 208. There are two door panels 209, symmetrically distributed on both sides of the guide groove 208. A drive plate 210 is fixedly connected to both sides of the door panel 209. The drive plate 210 has threaded holes inside. A reduction motor 212 is fixedly installed in the middle of the lifting box 201 near the guide groove 208. A bidirectional lead screw 211 is installed at the drive end of the reduction motor 212. The bidirectional lead screw 211 is composed of two symmetrically connected screw sections.

[0024] In the above scheme, the bidirectional lead screw 211 is driven by the geared motor 212, causing the two symmetrically distributed door panels 209 to slide synchronously in opposite directions along the guide groove 208. When the door panels 209 are closed, they form a complete support surface; when open, they completely avoid the block loading path. The threaded engagement between the drive plate 210 and the lead screw ensures the synchronous movement of the two door panels 209, preventing unilateral jamming. This design replaces the traditional manual bottom sealing operation, achieving automatic sealing after loading.

[0025] Furthermore, the lifting mechanism 1 includes a crossbeam frame 101, with a sliding seat 102 slidably connected inside the crossbeam frame 101. A dual-shaft winch 103 is fixedly mounted on the sliding seat 102. A drive screw 104 is threadedly connected to one side of the sliding seat 102, and a stepper motor that drives the drive screw 104 to rotate is mounted at one end of the crossbeam frame 101. The dual-shaft winch 103 includes a dual-shaft transmission box, with a drive motor mounted at the input end of the dual-shaft transmission box, and winding shafts mounted at the two output ends of the dual-shaft transmission box. A steel wire traction rope is mounted on the winding shaft, and the lower end of the steel wire traction rope is fixedly connected to the lifting seat 203 on the triangular hanger 202.

[0026] The sliding seat 102 on the crossbeam frame 101 achieves precise X-axis positioning via a stepper motor-driven screw 104. The symmetrical wire ropes of the dual-shaft winch 103 form stable lifting points via a triangular hanger 202. Synchronous dual-shaft winding and unwinding ensures the vertical movement of the lifting box 201 without tilting. This three-dimensional moving system enables the device to accurately cover any location in the storage yard, and, in conjunction with the automatic clamping system, achieves unmanned continuous operation.

[0027] The working principle of this block hoisting device is as follows: First, the lifting mechanism 1 encloses the entire block stack via the lifting box 201 of the loading and extraction mechanism 2 at its lower end. The bottom opening of the lifting box 201 facilitates contact with the stacked blocks. Clamping plates 204 are provided on both sides inside the lifting box 201, which are driven to move in opposite directions by an electric push rod 205. The chamfered structure on the clamping plates 204 forms a guide slope during clamping, automatically correcting the block's positional deviation and ensuring stable clamping of the blocks.

[0028] Once the block is secured by the clamping plate 204, the top door panel 209 of the lifting box 201 closes via a retractable closure assembly, forming a closed clamping space to prevent the block from slipping during hoisting. Drive plates 210 are fixed to both sides of the door panel 209, and slide synchronously via a reduction motor 212 and a bidirectional lead screw 211 system to achieve automatic sealing.

[0029] The lifting mechanism 1 is equipped with an adjustment assembly at the top for adjusting the position of the clamping plate 204. A telescopic cylinder 207 drives a high-strength guide plate 206 to move vertically, raising the clamping plate 204 and ensuring the block is completely detached from the ground. The sliding connection design of the electric push rod 205 allows the clamping plate 204 to move in both horizontal and vertical directions, reducing frictional loss.

[0030] A sliding seat 102 is slidably connected inside the crossbeam frame 101, and a dual-shaft winch 103 is fixed on the seat. A stepper motor drives the drive screw 104 to achieve precise X-axis positioning. The symmetrical steel wire ropes of the dual-shaft winch 103 are connected to the lifting seat 203 on the triangular hanger 202, forming a stable lifting point. Synchronous winding and unwinding of the dual shafts ensures that the lifting box 201 moves vertically without tilting, enabling the device to accurately cover any location in the storage yard.

[0031] Its overall working principle is as follows: First, the block stack is wrapped and fixed by the lifting mechanism 1; then, the automatic hoisting and sealing of the block is achieved by adjusting the position of the clamping plate 204 and the door panel 209; finally, the block is precisely hoisted to the designated position by the three-dimensional moving system of the crossbeam frame 101 and the dual-shaft winch 103 to achieve unmanned continuous operation.

[0032] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
