Description

Technical Field

[0001] This utility model relates to the field of wave pile technology, specifically a hoisting device suitable for wave piles. Background Technology

[0002] Wave piles are a new type of prestressed concrete component with a semi-circular cross-section. Currently, wave piles are mainly used in earthwork excavation support, slope retaining walls in water conservancy projects, and water-retaining construction.

[0003] To facilitate hoisting, the corrugated piles need to be sawn. After sawing, a steel wire rope is passed through the bottom of one side for hoisting, posing a significant safety hazard. Chinese Patent 202021953515.0 (Publication No. CN212953858U) discloses a "Corrugated Pile Lifting Tool," the technical solution of which is as follows: It includes a lifting tool body. On the same side of the lifting tool body, several pairs of bearing bodies are arranged in pairs, with the two bearing bodies in each pair having the same height. The lifting tool body is equipped with lifting lugs. The lifting tool body includes side plates on both sides, which are connected by a connecting plate in the middle. The bearing bodies are set on the side plates. The angle between the bearing surface of the bearing body and the vertical direction is 30°~120°. This patent avoids the safety hazards caused by threading steel wire ropes through the bottom of the pile and ensures safe operation. However, it has the following problems: the lifting device lifts the wave pile by setting the load on the two unconnected side plates. In windy weather or when the crane is running at high speed, the side plates on both sides of the wave pile are prone to shift due to the change in the center of gravity, which poses a great safety hazard and reduces work efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a hoisting device suitable for wave piles. It mainly solves the problem that existing hoisting devices are prone to causing the side plates on both sides of the wave pile to shift due to changes in the center of gravity during windy weather or when the crane is running at high speed, which poses a great safety hazard and reduces work efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hoisting device suitable for wave piles, including a connecting column, both ends of which are fixedly connected to a bearing frame, the bearing frame being semi-circular and the curvature matching the wave pile, several clamping blocks being fixedly connected along the extension direction of the bearing frame, the clamping blocks being C-shaped, and two lifting lugs being symmetrically fixedly connected to the upper end of the bearing frame.

[0006] The above structural design employs a semi-circular arc-shaped support frame precisely matched with the corrugated pile cross-section. The two sides of the support frame are rigidly connected by connecting columns to form an overall frame structure, effectively avoiding the center of gravity shift problem caused by the lack of connection between the side plates of traditional lifting equipment. C-shaped clamping blocks are arranged along the length direction to clamp the corrugated pile at multiple points, distributing the force and preventing the pile from sliding or falling off during lifting. The symmetrical arrangement of lifting lugs ensures uniform force distribution during lifting, further improving stability and reducing safety hazards.

[0007] Preferably, the connecting column includes a sleeve fixedly connected to the side wall of the support frame, one end of the sleeve is rotatably connected to a nut, a threaded rod extends into the sleeve, and the threaded rod is threadedly connected to the nut.

[0008] By adopting the above structural design, the length of the connecting column can be flexibly adjusted by rotating the nut to push the threaded rod to extend and retract within the sleeve, adapting to wave piles of different lengths, improving the versatility of the lifting equipment, and reducing equipment replacement costs.

[0009] Preferably, the upper end of the clamping block is threaded with a bolt, the lower end of the bolt is rotatably connected to a pressure plate, and the upper end of the bolt is provided with a rotating handle.

[0010] With the above structural design, the pressure plate is pressed down by rotating the handle to drive the bolt, thereby achieving rapid clamping and loosening of the wave pile, further fixing the wave pile and preventing it from falling off the support frame. The operator can adjust the bolt tightening force according to the surface condition of the wave pile to ensure uniform clamping force without damaging the pile body, thus taking into account both safety and protection.

[0011] Preferably, rubber pads are provided on the inner surfaces of both the pressure plate and the clamping block, and the rubber pads are matched with the curvature of the wave pile.

[0012] With the above structural design, the rubber pad provides a flexible contact surface, increases the coefficient of friction, and prevents the pile from sliding during hoisting. The elastic material of the rubber pad prevents the pressure plate and clamping block from directly squeezing the surface of the corrugated pile, preventing concrete cracking or scratches and ensuring the quality of the finished product.

[0013] Compared with the prior art, this utility model provides a hoisting device suitable for wave piles, which has the following beneficial effects: The device employs a semi-circular arc-shaped support frame precisely matched to the corrugated pile cross-section. The two sides of the support frame are rigidly connected by connecting columns to form an integrated frame structure, effectively avoiding the center-of-gravity shift problem caused by the lack of connection between the side plates in traditional lifting equipment. C-shaped clamping blocks are arranged along the length direction, clamping the corrugated pile at multiple points to distribute the force and prevent the pile from sliding or falling off during lifting. Through its overall structural design, adjustable connecting columns, rapid clamping mechanism, and flexible protective components, this lifting device systematically solves the safety hazards of offset, complex operation, and pile damage problems inherent in traditional lifting equipment, achieving safe and efficient corrugated pile lifting operations.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-3 This utility model provides a hoisting device suitable for wave piles, including a connecting column 3. Both ends of the connecting column 3 are fixedly connected to a bearing frame 1. The bearing frame 1 is semi-circular and the curvature matches the wave pile. Four clamping blocks 2 are fixedly connected in the extension direction of the bearing frame 1. The clamping blocks 2 are C-shaped. Two lifting lugs 4 are symmetrically fixedly connected to the upper end of the bearing frame 1.

[0017] The connecting column 3 includes a sleeve 301 fixedly connected to the side wall of the support frame 1. A nut 303 is rotatably connected to one end of the sleeve 301. A threaded rod 302 extends into the sleeve 301 and is threadedly connected to the nut 303.

[0018] The upper end of the clamping block 2 is threaded with a bolt 202, the lower end of the bolt 202 is rotatably connected to a pressure plate 201, and the upper end of the bolt 202 is provided with a rotating handle 203.

[0019] Both the pressure plate 201 and the clamping block 2 are provided with rubber pads 5 on their inner sides, and the rubber pads 5 are matched with the curvature of the wave pile.

[0020] Working principle: First, the operator adjusts the length of the connecting column 3 according to the length of the wave pile: by rotating the nut 303, the threaded rod 302 is pushed to extend and retract within the sleeve 301, so that the spacing of the two bearing frames 1 on both sides matches the size of the wave pile; the hoisting device is placed above the wave pile, so that the semi-circular bearing frame 1 fits the arc surface of the wave pile, ensuring that the two bearing frames on both sides are symmetrically distributed, and the length of the connecting column 3 is adjusted again so that the two end side walls of the wave pile are inserted into the clamping block 2. The rotating handle 203 on each clamping block 2 is manually rotated to drive the bolt 202 to press down the pressure plate 201, so that the pressure plate 201 fits tightly against the side wall of the wave pile. The rubber pad 5 provides anti-slip and cushioning functions to avoid damage to the pile body; connect the crane hook to the lifting lug 4 at the upper end of the support frame 1 to ensure that the lifting rope is evenly stressed and the crane is slowly lifted. Through the rigid connection of the connecting column 3, the support frames on both sides are stressed synchronously to prevent the wave pile from tilting or overturning due to the shift of the center of gravity; after the wave pile is lifted to the designated position, it is slowly lowered to the target foundation or installation point. Rotate the handle 203 in the opposite direction to loosen the bolt 202, so that the pressure plate 201 is separated from the wave pile, completing the unloading. Disassemble the lifting device and proceed to the next round of lifting operations.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
