Description

Technical Field

[0001] This utility model relates to the field of bridge construction equipment, specifically to a bridge construction hoisting auxiliary device. Background Technology

[0002] During bridge construction, a large amount of steel bars are required. Most of these steel bars have a circular cross-section, making them very prone to slippage during hoisting. External vibrations can easily cause the steel bars to wobble, resulting in poor stability and a risk of them slipping off, thus reducing safety. Manual handling is time-consuming, labor-intensive, and inefficient.

[0003] Chinese utility model patent CN215249123U discloses a steel bar lifting device for bridge construction, relating to the field of bridge construction. Addressing the problems of poor stability and cumbersome unloading in existing steel bar lifting devices, the following solution is proposed: It includes a mounting frame. A motor is fixedly mounted on the left end of the mounting frame. The output shaft of the motor is connected to a winding shaft. The right end of the winding shaft passes through the mounting frame and is rotatably connected to the right inner surface of the mounting frame. Two winding wheels are fixedly mounted on the winding shaft. Two sliding grooves are symmetrically formed on the left and right walls of the inner side of the mounting frame, and both grooves are arranged vertically. A slider is slidably mounted in each of the two grooves. A guide rod is fixedly mounted at one end of each slider, close to each other. A storage box is fixedly mounted between the two guide rods. This utility model has good stability, good protection effect, facilitates unloading, is simple to operate, and is highly practical.

[0004] However, in the above-mentioned device, the storage box has a fixed size, and the two ends of the steel bars cannot be restricted during the hoisting process, which may cause the steel bars to slide axially with each other. Utility Model Content

[0005] The purpose of this utility model is to provide a reasonably designed bridge construction hoisting auxiliary device that addresses the defects and shortcomings of the existing technology and can solve the aforementioned defects.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: It includes an outer support frame, with several moving wheels at the bottom of the outer support frame and two sets of power mechanisms at the top of the outer support frame. A limiting box for placing steel bars is provided inside the outer support frame. The power mechanisms are respectively connected to the limiting box via steel wire ropes. Two storage compartments are formed inside the limiting box through a middle partition. A top plate is connected to the top of the middle partition. An inlet is formed between the top of the outer side of the storage compartment and the top plate. The bottom of each storage compartment is a slope, and lateral adjustment structures are provided at both ends of each storage compartment. A channel for steel bar discharge is opened at the bottom of the storage compartment, and a discharge control structure is provided below the channel.

[0007] Preferably, the lateral adjustment structure includes multiple adjusting telescopic cylinders installed on the limiting box. The top of the movable rod of the adjusting telescopic cylinder moves through the side wall of the limiting box and is connected to a movable plate. The shape of the movable plate is the same as the cross-sectional shape inside the storage compartment, and a gap is left between the edge of the movable plate and the side wall inside the storage compartment.

[0008] Preferably, the discharge control structure includes a support frame connected to the bottom of the limiting box, and a discharge control door is connected to the support frame via several door opening and telescopic cylinders. The shape of the discharge control door matches the shape of the bottom channel of the two storage compartments.

[0009] Preferably, the discharge control door is provided with a slope at the passage, and the two slopes are symmetrically arranged facing both sides.

[0010] Preferably, the power mechanism includes two support blocks mounted on the outer support frame, a rotating shaft rotatably mounted between the two support blocks, multiple winches mounted on the rotating shaft, one end of the wire rope connected to the winch, and the other end of the wire rope movably passing through the top wall of the outer support frame and connected to the top plate of the limit box. A motor is provided on the outer support frame, and a reducer is connected to the front end of the motor. The output end of the reducer is connected to the rotating shaft through a sprocket assembly.

[0011] Preferably, the top plate is connected to several hooks by ropes, and the top of the outer support frame is provided with several retaining rings.

[0012] The beneficial effects of this utility model after adopting the above structure are:

[0013] 1. This utility model uses a lateral adjustment structure to adjust the position of the movable plate, thereby positioning and clamping the reinforcing bars to prevent slippage during hoisting and movement.

[0014] 2. This utility model features a sloped design, allowing the reinforcing bars to automatically gather after insertion, and also incorporates a discharge control system.

[0015] The structure allows the discharge control door to be opened via a telescopic cylinder, enabling automatic discharge of the reinforcing bars. It is simple, convenient, and quick to use. With movable wheels, the reinforcing bars can be directly transferred after being lifted. Attached Figure Description

[0022] 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.

[0023] See Figures 1-4 As shown, it includes an outer support frame 1, with several movable wheels 2 at the bottom of the outer support frame 1. The movable wheels 2 are preferably load-bearing universal wheels. Two sets of power mechanisms are provided at the top of the outer support frame 1. A limiting box 3 for placing steel bars is provided inside the outer support frame 1. The power mechanisms are respectively connected to the limiting box 3 via steel wire ropes. Two storage compartments 302 are formed inside the limiting box 3 by a middle partition 305. A top plate 301 is connected to the top of the middle partition 305. An inlet 304 is formed between the top of the outer side of the storage compartment 302 and the top plate 301. The bottom of each storage compartment 302 is a slope 303, and a lateral adjustment structure is provided at both ends of each storage compartment 302. A channel for steel bar discharge is opened at the bottom of the storage compartment 302, and a discharge control structure is provided below the channel.

[0024] See Figures 1-4 As shown, the lateral adjustment structure includes multiple adjusting telescopic cylinders 309 installed on the limiting box 3. The top of the movable rod of the adjusting telescopic cylinder 309 moves through the side wall of the limiting box 3 and is connected to a movable plate 310. The shape of the movable plate 310 is the same as the inner cross-sectional shape of the storage compartment 302, and a gap is left between the edge of the movable plate 310 and the inner side wall of the storage compartment 302.

[0025] As an optimized solution of this utility model, by adjusting the extension and retraction of the telescopic cylinder 309, the movable plate 310 is moved. The movable plates 310 on both sides move inward or outward at the same time, thereby adjusting the distance between them, so as to adapt to steel bars of different lengths, clamp them, and prevent the steel bars from slipping during hoisting.

[0026] See Figures 1-3As shown, the discharge control structure includes a support frame 307 connected to the bottom of the limit box 3. The support frame 307 is connected to a discharge control door 306 via several door opening and telescopic cylinders 308. The shape of the discharge control door 306 matches the shape of the bottom channel of the two storage compartments 302. The discharge control door 306 is provided with a slope at the channel, and the two slopes are symmetrically arranged on both sides.

[0027] As an optimized solution of this utility model, the extension and retraction of the door telescopic cylinder 308 controls the rise and fall of the discharge control door 306. After the discharge control door 306 rises and reaches the entrance of the channel, the channel can be closed to prevent the steel bars from falling out. After the discharge control door 306 falls down, the steel bars can fall from the channel and slide out along the slope above the discharge control door 306.

[0028] See Figures 1-2 As shown, the power mechanism includes two support blocks 4 mounted on the outer support frame 1. A rotating shaft 5 is rotatably mounted between the two support blocks 4. Multiple winches 6 are mounted on the rotating shaft 5. One end of a wire rope is connected to the winch 6, and the other end of the wire rope passes through the top wall of the outer support frame 1 and is connected to the top plate 301 of the limit box 3. A motor 7 is provided on the outer support frame 1. A reducer 8 is connected to the front end of the motor 7. The output end of the reducer 8 is connected to the rotating shaft 5 through a sprocket assembly 9. Several hooks 11 are connected to the top plate 301 by ropes. Several retaining rings 10 are provided at the top position inside the outer support frame 1.

[0029] As an optimized solution of this utility model, the motor 7 drives the rotating shaft 5 and the winch 6 to rotate through the reducer 8, thereby raising or lowering the limit box 3. After it is raised to the correct position, the hook 11 can be hooked onto the retaining ring 10 to achieve positioning and prevent the limit box 3 from shaking.

[0030] The principle and usage process of this utility model:

[0031] In use, first start the motor 7 to drive the winch 6 to rotate, loosen the wire rope, and lower the limit box 3. Then, adjust the telescopic cylinder 309 according to the width of the rebar so that the distance between the two movable plates 310 is slightly greater than the length of the rebar. Then, put the rebar into the inlet 304. The rebar will automatically slide down and stack up under the action of the slope. During the placement process, the amount placed in the two storage bins 302 should be the same to keep the center of gravity of the limit box 3 stable. After the placement is completed, start the telescopic cylinder 309 again to clamp the rebar through the movable plate 310 to prevent the rebar from sliding in the limit box 3. Then, start the motor 7 to drive the winch 6 to retract the wire rope and lift the limit box 3. Then, hang the hook 11 on the shackle 10 to position the limit box 3.

[0032] Then, the device can be pushed to move the steel bars to the designated area, and the steel bars can be discharged after opening.

[0033] It should be understood that the above-described specific embodiments of this utility model are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within the protection scope of this utility model. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
