Abstract
Description
Technical Field
[0001] This utility model relates to the field of building engineering technology, specifically to a synchronous rotation device for the screw sleeve of a drilled pile reinforcement cage. Background Technology
[0002] A steel reinforcement cage is a cage-like structure made of welded or tied steel bars. The main function of a steel reinforcement cage is the same as that of the longitudinal steel bars in a column, mainly to resist tension. Steel reinforcement cages play an important role in various construction projects.
[0003] During the fabrication of the reinforcing cage, multiple reinforcing bars need to be connected according to the design dimensions and positions. There are two connection methods: welding and threaded connection using a screw rod sleeve. The screw rod sleeve connection involves setting positive and negative threads at both ends of the reinforcing bars, and then screwing the ends of the two reinforcing bars into the screw rod sleeve to complete the connection. Since the reinforcing cage is a circular cage composed of multiple reinforcing bars, multiple screw rod sleeves are required when connecting multiple cages. Each screw rod sleeve needs to be tightened manually, which is labor-intensive and tedious, negatively impacting work efficiency. Therefore, a synchronous rotation device for the screw rod sleeves of bored pile reinforcing cages is proposed. Utility Model Content
[0004] This utility model aims to solve at least one of the technical problems existing in the prior art.
[0005] Therefore, one objective of this utility model is to propose a synchronous rotation device for the screw sleeve of a bored pile reinforcement cage. This synchronous rotation device for the screw sleeve of a bored pile reinforcement cage can realize the synchronous rotation of multiple screw sleeves, accelerate the connection speed between the screw sleeve and the positive and negative threads at both ends of the two reinforcing bars, improve work efficiency, and reduce workload.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a synchronous rotation device for the threaded sleeve of a bored pile reinforcement cage, comprising two semi-annular plates and multiple sets of semi-circular tubes. Each end of the semi-annular plate is fixedly connected to a first connecting plate. The first connecting plates on the two semi-annular plates are fixedly connected via first threaded connectors. Each set of semi-circular tubes consists of two tubes. Multiple second connecting plates are fixedly connected to the outside of each of the two semi-circular tubes. A through hole is opened inside the second connecting plate, and a second threaded connector is inserted into the through hole. The two semi-circular tubes are fixedly connected via the second threaded connectors. External teeth are fixedly connected to the outside of each semi-circular tube, and internal teeth are fixedly connected to the inside of each semi-annular plate. The internal teeth mesh with the external teeth.
[0007] Preferably, each of the two semi-annular plates is fixedly connected to three handles on its exterior.
[0008] Preferably, three rubber pads are bonded to the inside of the semi-circular tube.
[0009] Preferably, the pitch and height of the internal teeth and the external teeth are the same.
[0010] Preferably, the length of the internal tooth is less than the length of the external tooth.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] This invention uses a set of semi-circular tubes, the same number as the number of threaded sleeves in the reinforcing cage, to connect the sleeve structure to the outside of the threaded sleeve. Then, a second threaded connector is used to fix two semi-circular tubes to the outside of the threaded sleeve. Rotating the handle causes the outer ring to rotate, which in turn causes the inner teeth to drive the outer teeth to rotate, thus enabling the sleeve structure to drive the threaded sleeve to rotate. This achieves synchronous rotation of multiple threaded sleeves, speeds up the connection between the threaded sleeve and the positive and negative threads at both ends of the two reinforcing bars, improves work efficiency, and reduces workload.

[0019] 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.
[0020] Please see Figures 1-5 The present invention provides a synchronous rotation device for the screw sleeve of a drilled pile reinforcement cage, comprising: two semi-annular plates 1 and multiple sets of semi-circular tubes 2. Both ends of the semi-annular plates 1 are fixedly connected to a first connecting plate 3. The first connecting plates 3 on the two semi-annular plates 1 are fixedly connected by a first threaded connector 4. Each set of semi-circular tubes 2 consists of two tubes. Multiple second connecting plates 8 are fixedly connected to the outside of the two semi-circular tubes 2. The inside of the second connecting plate 8 is provided with a through hole 10. A second threaded connector 9 is inserted into the inside of the through hole 10. The two semi-circular tubes 2 are fixedly connected by the second threaded connector 9. External teeth 7 are fixedly connected to the outside of the semi-circular tubes 2. Internal teeth 6 are fixedly connected to the inside of the semi-annular plates 1. The internal teeth 6 mesh with the external teeth 7.
[0021] In use, the specific number of semicircular tubes 2 is the same as the number of threaded sleeves of the reinforcing cage, and the diameter of the sleeve structure formed by each group of semicircular tubes 2 is the same as the diameter of the threaded sleeve. The sleeve structure formed by one group of semicircular tubes 2 is sleeved on the outside of the threaded sleeve, and then the two semicircular tubes 2 are fixed on the outside of the threaded sleeve using the second threaded connector 9.
[0022] The semi-circular tube 2 has three rubber pads 11 bonded inside. Therefore, when the semi-circular tube 2 is fixed to the outside of the screw sleeve, the rubber pads 11 have a certain thickness, and the diameter of the sleeve structure formed by the semi-circular tubes 2 is the same as the diameter of the screw sleeve. The two second connecting plates 8 will not directly contact each other. When the two semi-circular tubes 2 are fixed by the second threaded connector 9, the rubber pads 11 and the screw sleeve can be clamped simultaneously, which enhances the friction between the semi-circular tube 2 and the screw sleeve and thus has a better anti-slip effect.
[0023] Each of the two semi-circular plates 1 has three handles 5 fixedly connected to its exterior.
[0024] When fixing the two semi-annular plates 1 together, it is necessary to adjust the angle of each sleeve structure so that the internal teeth 6 match the external teeth 7 of each sleeve structure. This prevents the two semi-annular plates 1 from not being able to connect when they are joined together and fixed to form the outer ring using the first threaded connector 4, because the internal teeth 6 and external teeth 7 are not meshed.
[0025] Rotating handle 5 causes the outer ring to rotate, which in turn causes the inner tooth 6 to drive the outer tooth 7 to rotate, thereby enabling the sleeve structure to drive the lead screw sleeve to rotate.
[0026] In order to enable the internal tooth 6 and the external tooth 7 to mesh and match during use, the tooth pitch and tooth height of the internal tooth 6 and the external tooth 7 are the same.
[0027] In order to prevent the connection from being unstable due to different positions after the multiple sets of semicircular tubes 2 are combined, the length of the inner tooth 6 is less than the length of the outer tooth 7, so that the multiple sets of semicircular tubes 2 with different front and rear positions can be driven by the semi-annular plate 1 and the inner tooth 6.
[0028] Based on the above technical solution, the working steps of this solution are summarized as follows: When using this utility model, the specific number of semicircular tubes 2 is the same as the number of screw sleeves of the reinforcing cage, and the diameter of the sleeve structure formed by each group of semicircular tubes 2 is the same as the diameter of the screw sleeve. The sleeve structure formed by one group of semicircular tubes 2 is sleeved on the outside of the screw sleeve. Then, the second threaded connector 9 is used to fix the two semicircular tubes 2 on the outside of the screw sleeve. When fixing the two semi-annular plates 1, it is necessary to adjust the angle of each sleeve structure so that the inner teeth 6 match the outer teeth 7 of each sleeve structure. This prevents the two semi-annular plates 1 from being unable to be connected when they are joined together and fixed with the first threaded connector 4 to form the outer ring because the inner teeth 6 and the outer teeth 7 are not meshed. Turning the handle 5 makes the outer ring rotate, thereby causing the inner teeth 6 to drive the outer teeth 7 to rotate, and thus enabling the sleeve structure to drive the screw sleeve to rotate.
[0029] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model 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 this utility model, the scope of which is defined by the appended claims and their equivalents.
