Detailed Implementation

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0029] Example 1 Reference Figures 1-4 This is the first embodiment of the present utility model. This embodiment provides a multi-functional rebar positioning frame for prefabricated component production. The multi-functional rebar positioning frame for prefabricated component production includes a support mechanism 100, a positioning adjustment mechanism 200, and a drive fixing mechanism 300. The support mechanism 100 can support the positioning frame. With the cooperation of the drive fixing mechanism 300, the positioning adjustment mechanism 200 can make the straight rebars evenly distributed on the ring rebars, reducing the processing time of a single product.

[0030] Specifically, the support mechanism 100 includes a housing 101, on which limit holes 102 are provided. There are several limit holes 102, and one limit rod 303a corresponds to four limit holes 102, which correspond to four positions respectively. When inserted into the corresponding limit hole 102, the position of multiple placement frames 205 can be adjusted and limited to meet the positioning of steel bars in the production of precast steel cage components of different specifications.

[0031] Specifically, the positioning adjustment mechanism 200 is installed on the housing 101 and includes a turntable 201 rotatably connected inside the housing 101. The turntable 201 has guide holes 202. Multiple guide holes 202 are provided on one turntable 201. The number of guide holes 202, square plates 203, and placement racks 205 are the same. By setting the guide holes 202, when the turntable 201 is driven to rotate, the short rod 204 moves within the guide holes 202, thereby moving the square plates 203 and the placement racks 205 on them, changing the position of multiple placement racks 205, and adjusting the diameter of the circle formed by the steel bars placed on them. It can be used for the production of steel cages with different diameters.

[0032] A square plate 203 is slidably connected to the shell 101. A short rod 204 is fixedly connected to one end of the square plate 203 and is slidably connected to the guide hole 202. A placement frame 205 is fixedly connected to the other end of the square plate 203. The placement frame 205 supports and limits the steel bars. The circular steel bars are welded one by one to the ring frame formed by the steel bars on the placement frame 205. After welding one, it is pulled, and then the next one is welded. This operation does not affect the removal of the steel cage from the positioning frame.

[0033] Specifically, the drive fixing mechanism 300 is installed on the housing 101 and disposed on the surface of the turntable 201. It includes a rotating rod 301 rotatably connected to the housing 101, with one end fixedly connected to the surface of the turntable 201. The rotating rod 301 is rotatably connected to the housing 101 via a bearing. The other end of the rotating rod 301 is fixedly connected to a connecting frame 302. The connecting frame 302 provides a position for the installation of the fixing member 303. The fixing member 303 is installed on the connecting frame 302 and disposed on the surface of the housing 101. By setting the fixing member 303, the connecting frame 302 after rotation adjustment can be positioned between the housing 101 and the rotating rod 301, thereby positioning the rotating rod 301 and the turntable 201, thereby limiting the short rod 204, the square plate 203 and the placement frame 205, so that they are fixed after movement adjustment and will not move again.

[0034] Example 2 Reference Figures 2-7 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0035] Specifically, a support plate 103 is fixedly connected to the bottom of the housing 101. Two support plates 103 are welded to the bottom of the housing 101. An installation plate 104 is fixedly connected to one side of the support plate 103. The support plate 103 supports the housing 101. The installation plate 104 has installation holes, which facilitate positioning and fixing on the ground with expansion bolts.

[0036] A reinforcing plate 105 is fixedly connected to the support plate 103 and to the top of the mounting plate 104. Two reinforcing plates 105 are welded to the support plate 103 and the mounting plate 104. The reinforcing plates 105 reinforce the support plate 103 and the mounting plate 104, improve the stability between the support plate 103 and the mounting plate 104, and make the positioning frame more secure during use.

[0037] A cover plate 106 is fixedly connected to the housing 101. A number of balls 206 are provided between the turntable 201 and the housing 101. By setting the balls 206, the turntable 201 can be limited within the housing 101, allowing it to rotate within the housing 101 without moving. An annular groove is formed between the outer surface of the turntable 201 and the inner wall of the housing 101, and the balls 206 are slidably connected within it. The annular groove can limit the balls 206, thereby limiting the distance between the turntable 201 and the housing 101.

[0038] The placement frame 205 has a rotating roller 207. Two rollers 207 are rotatably connected inside one placement frame 205. The rollers 207 can support the steel bars inside the placement frame 205 and reduce the resistance when the steel bars are pulled, making it more convenient and labor-saving.

[0039] The fixing component 303 includes a limiting rod 303a slidably connected to the connecting frame 302. One end of the limiting rod 303a is inserted into the limiting hole 102. A ring plate 303b is provided with multiple limiting rods 303a. The limiting rod 303a passes through the connecting frame 302 and is slidably connected to it. One end of the limiting rod 303a is chamfered. With this setting, it is convenient to smoothly insert the limiting rod 303a into the limiting hole 102. The limiting hole 102 cooperates with the limiting rod 303a. When the limiting rod 303a is inserted into it, it limits the connecting frame 302, and then limits the rotating rod 301 and the turntable 201.

[0040] One end of the limiting rod 303a is fixedly connected to the ring plate 303b. Multiple limiting rods 303a are fixed on a ring plate 303b. By pulling the ring plate 303b, multiple limiting rods 303a can be moved to disengage from the limiting hole 102. A spring 303c is sleeved on the surface of the limiting rod 303a, and its two ends are fixedly connected to the surface of the connecting frame 302 and the ring plate 303b, respectively.

[0041] By using spring 303c, a force is applied to ring plate 303b when limit rod 303a is inserted into limit hole 102, so that limit rod 303a is stably inserted into limit hole 102 and will not be released from the limit without human intervention. A handle 303d is fixedly connected to the connecting frame 302. The handle 303d is designed to be easy to hold with one hand and pull to move ring plate 303b, thereby moving multiple limit rods 303a.

[0042] A limiting groove 303e is formed on the surface of the limiting rod 303a, and a limiting block 303f is fixedly connected to the connecting frame 302 and slidably connected in the limiting groove 303e. Through the setting of the limiting groove 303e and the limiting block 303f, the limiting rod 303a can be guided and limited, so that the limiting rod 303a will not detach from the connecting frame 302 when it moves.

[0043] A rocker arm 304 is fixedly connected to the connecting frame 302. Rotating the rocker arm 304 facilitates the rotation of the connecting frame 302, which in turn drives the rotating rod 301 and the turntable 201 to rotate.

[0044] When in use, hold the handle 303d and pull it to move the ring plate 303b and the limiting rod 303a, so that the spring 303c is stretched and the limiting rod 303a is disengaged from the original limiting hole 102. Then, turn the rocker arm 304 to rotate the connecting frame 302 and the short rod 204, which in turn rotates the turntable 201, so that the short rod 204 moves in the guide hole 202 on the turntable 201, and the square plate 203 and the placement frame 205 are moved outward.

[0045] After adjustment, gradually loosen the handle 303d. Under the action of the spring 303c, the ring plate 303b and the limiting rod 303a will move back, so that the limiting rod 303a is inserted into the limiting hole 102, which limits the connecting frame 302 and the rotating rod 301, and then limits the turntable 201, the short rod 204, the square plate 203 and the placement frame 205.

[0046] According to the requirements of prefabrication of steel cages, the required steel bars are placed on the corresponding placement frame 205, and then the outer ring steel bars are fitted onto one end of the ring frame and welded. After welding, the frame is pulled, and then the next one is welded. The operation is carried out in sequence. During the operation, a support moving frame can be set at one end to support the welded parts.

[0047] In summary, with the cooperation of the positioning and adjusting mechanism 200 and the driving and fixing mechanism 300, the straight steel bars can be evenly distributed on the ring steel bars. Compared with the existing technology, this reduces the impact on the compactness of subsequent concrete pouring, reduces the processing time of individual products, and thus improves the overall construction progress.

[0048] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
