Description

Technical Field

[0001] This utility model relates to the field of on-site preparation technology of building materials or building components, and in particular to an adjustable PC precast component rebar tying auxiliary device. Background Technology

[0002] PC precast components are a type of component used in construction, transportation, water conservancy and other fields. They refer to concrete products that are processed and produced in factories using standardized and mechanized methods. Chinese utility model patent, authorized announcement number "CN220058903U", discloses an auxiliary device for tying reinforcement bars of continuous beams. This utility model is easy to operate, highly efficient, reusable, and has low manufacturing and maintenance costs. It also has stable performance and standardized operation, preventing the reinforcement cage from falling and directly crushing the operator's arm during operation, thus giving the device high safety performance.

[0003] While the above-mentioned technical solution can lift the rebar cage to prevent it from falling and injuring workers, it requires two workers to operate the rack and pinion jacks simultaneously to ensure the cage remains level. This process not only requires workers to have a high level of operational skill but also to communicate the lifting speed in real time. The slightest mistake can cause the cage to tilt or even slip, making the operation quite cumbersome. Therefore, we propose an adjustable PC precast component rebar binding auxiliary device. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide an adjustable PC precast component rebar binding auxiliary device. This device can solve the problem that although it can lift the rebar cage to prevent it from falling and injuring workers, it requires two workers to operate the rack and pinion jacks at the same time to ensure that the rebar cage is kept horizontal through synchronous lifting. This process not only requires workers to have a high level of operational proficiency, but also requires real-time communication of the lifting speed. If the worker is not careful, the rebar cage may tilt or even slip, making the operation process cumbersome.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable PC precast component rebar tying auxiliary device, comprising:

[0006] The support frame has two support bases fixedly connected to its bottom;

[0007] Auxiliary fall protection structure, located on the support frame;

[0008] The auxiliary fall arrest structure includes a winding box, a ratchet, a rotating shaft, and a throttle. A through hole is provided at the top of the support frame. The winding box is fixedly connected to the top of the support frame. The rotating shaft is rotatably connected inside the winding box, and both ends of the rotating shaft extend to the outside of the winding box. The throttle is fixedly connected to the outer surface of the rotating shaft. The ratchet is fixedly sleeved on the outer surface of the rotating shaft. Two limit discs are fixedly sleeved on the outer surface of the rotating shaft. Both limit discs are located inside the winding box. A hoisting rope is wound around the outer surface of the rotating shaft. The bottom end of the hoisting rope passes through the through hole and is fixedly connected to a mounting base. A lifting crossbar is installed inside the mounting base.

[0009] Preferably, the auxiliary fall arrestor structure further includes a mounting cylinder, a limiting slide plate, a connecting rod, and a locking block. The mounting cylinder is fixedly connected to the top of the support frame. A sliding groove is provided on the outer surface of the mounting cylinder. The limiting slide plate is slidably connected to the inside of the mounting cylinder. The connecting rod is fixedly connected to the top of the limiting slide plate. The top end of the connecting rod slides to the outside of the mounting cylinder and is fixedly connected to the locking block. The locking block engages with a ratchet. A spring is fixedly connected to the bottom of the limiting slide plate.

[0010] Preferably, the spring is located inside the mounting cylinder, and the bottom end of the spring is fixedly connected to the inner bottom wall of the mounting cylinder.

[0011] Preferably, the throttle is located outside the winding box and has an "L" shaped structure.

[0012] Preferably, the support frame has a "U" shaped structure.

[0013] Preferably, a reinforcing triangular plate is fixedly connected to the top of each of the two support bases.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This adjustable PC precast component rebar tying auxiliary device allows a single operator to lift and lower the rebar cage using a throttle and rotating shaft. This eliminates the need for two workers to simultaneously lift the cage, as the hoisting rope can be wound and released with a single hand rotation of the throttle. The ratchet and locking block, with their unidirectional engagement, automatically lock the rotating shaft after the rebar cage is lifted to the target height. This maintains stable rope tension without requiring continuous manual force, reducing reliance on worker skill and simplifying the operation of the fall protection structure.

[0025] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0026] Please see Figure 1-4 This utility model provides a technical solution: an adjustable PC precast component rebar tying auxiliary device, comprising:

[0027] Support frame 1, with two support bases 2 fixedly connected to the bottom of support frame 1, and a reinforcing triangular plate fixedly connected to the top of each of the two support bases 2. Support frame 1 has a "U" shaped structure.

[0028] An auxiliary fall protection structure is located on the support frame 1.

[0029] The auxiliary fall arrest structure includes a winding box 3, a ratchet 7, a rotating shaft 8, and a throttle 10. The top of the support frame 1 has a through hole 9. The winding box 3 is fixedly connected to the top of the support frame 1. The rotating shaft 8 is rotatably connected to the inside of the winding box 3. Both ends of the rotating shaft 8 extend to the outside of the winding box 3. The throttle 10 is fixedly connected to the outer surface of the rotating shaft 8. The throttle 10 is located outside the winding box 3 and has an "L" shaped structure. The ratchet 7 is fixedly sleeved on the outer surface of the rotating shaft 8. Two limiting discs 12 are fixedly sleeved on the outer surface of the rotating shaft 8. Both limiting discs 12 are located inside the winding box 3. A hoisting rope 6 is wound around the outer surface of the rotating shaft 8. The bottom end of the hoisting rope 6 passes through the through hole 9 and is fixedly connected to a mounting base 5. A lifting crossbar 4 is installed inside the mounting base 5.

[0030] The auxiliary fall arrest structure also includes a mounting cylinder 11, a limiting slide plate 15, a connecting rod 14, and a locking block 13. The mounting cylinder 11 is fixedly connected to the top of the support frame 1. A sliding groove 17 is provided on the outer surface of the mounting cylinder 11. The limiting slide plate 15 is slidably connected to the inside of the mounting cylinder 11. The connecting rod 14 is fixedly connected to the top of the limiting slide plate 15. The top end of the connecting rod 14 slides to the outside of the mounting cylinder 11 and is fixedly connected to the locking block 13. The locking block 13 is engaged with the ratchet 7. A spring 16 is fixedly connected to the bottom of the limiting slide plate 15.

[0031] Spring 16 is located inside mounting cylinder 11, and the bottom end of spring 16 is fixedly connected to the inner bottom wall of mounting cylinder 11.

[0032] Furthermore, when using the device, the operator drives the rotating shaft 8 to rotate inside the winding box 3 by rotating the "L"-shaped throttle 10. The outer surface of the rotating shaft 8 is wrapped with the lifting rope 6. As the rotating shaft 8 rotates, the lifting rope 6 is gradually wound up and drives the mounting base 5 and the lifting crossbar 4 to rise vertically through the through hole 9 at the top of the support frame 1, thereby lifting the steel cage.

[0033] The limiting discs 12 at both ends of the rotating shaft 8 prevent the hoisting rope 6 from shifting axially during the winding process, ensuring hoisting stability. The ratchet 7 is fixedly sleeved on the rotating shaft 8. When the hoisting rope 6 bears the weight of the steel cage, the ratchet 7 is subject to a unidirectional rotation tendency. At this time, the locking block 13 in the mounting cylinder 11, under the elastic force of the spring 16, is kept in a locking state with the ratchet 7 through the connecting rod 14 and the limiting slide plate 15, preventing the rotating shaft 8 from rotating in the opposite direction and preventing the steel cage from falling.

[0034] If it is necessary to lower the height of the steel cage, the operator needs to manually press down the limiting slide plate 15, so that the limiting slide plate 15 drives the locking block 13 to move downward through the connecting rod 14, thereby compressing the spring 16 and disengaging the locking block 13 from the ratchet 7. At this time, the handle 10 can be rotated in the opposite direction to release the hoisting rope 6. The support frame 1 adopts a "U" shaped structure, and the bottom is fixed by two support bases 2. A reinforcing triangular plate is added to the top of the support base 2 to enhance the anti-overturning ability and adapt to the ground conditions of different construction sites.

[0035] This device, with its throttle 10 and rotating shaft 8, allows a single operator to lift and lower the steel cage, eliminating the need for the cumbersome process of two workers simultaneously lifting it. The hoisting rope 6 can be wound and released simply by rotating the throttle with one hand. Through the one-way engagement of the ratchet 7 and the locking block 13, after the steel cage is lifted to the target height, the spring 16 drives the locking block 13 to automatically lock the rotating shaft 8. This maintains stable rope tension without the need for continuous manual force, reducing reliance on worker skill and simplifying the operation of the fall arrestor structure.

[0036] Structural Description: Support Frame 1: As the main frame of the device, it has a "U" shaped structure. The top has a through hole 9 for the suspension rope 6 to pass through, and the bottom is fixed with a support base 2, providing support and installation foundation for the whole;

[0043] Rotating shaft 8: Rotatably connected inside the winding box 3, with the lifting rope 6 wound around its outer surface. By rotating to wind up or release the lifting rope 6, the steel cage is driven to rise and fall.

[0044] The throttle 10 is L-shaped and fixed to the outer surface of the rotating shaft 8. The operator drives the rotating shaft 8 to rotate by rotating the throttle 10, thereby manually controlling the hoisting process.

[0045] Mounting cylinder 11: Fixed to the top of support frame 1, with components such as limiting slide plate 15 and spring 16 installed inside, providing installation space for auxiliary anti-fall structure;

[0046] Limiting disc 12: It is fixedly sleeved at both ends of the rotating shaft 8 and located inside the winding box 3 to prevent the lifting rope 6 from axially shifting during the winding process and to ensure the stability of the lifting.

[0047] Locking block 13: Engages with ratchet 7 and prevents the rotating shaft 8 from rotating in the opposite direction under the elastic force of spring 16. When it is necessary to lower the steel cage, it can be manually disengaged from ratchet 7 to release the lock.

[0048] Connecting rod 14: connects the limiting slide plate 15 and the locking block 13, transmits the displacement of the limiting slide plate 15, and makes the locking block 13 move with the limiting slide plate 15 to achieve engagement or disengagement with the ratchet 7;

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
