Description

Technical Field

[0001] This utility model relates to the field of PC component production equipment technology, and in particular to an auxiliary fixing device for PC component production. Background Technology

[0002] In the production of precast concrete (PC) components, the fixing of reinforcing bars is a crucial step. Existing auxiliary fixing devices suffer from problems such as insufficient operational flexibility, limited adaptability, poor transportation stability, and a lack of intelligent control. For example, it is difficult to quickly adjust clamping parameters when faced with reinforcing bars of different specifications and arrangements; they cannot effectively fix complex shapes and irregularly arranged reinforcing bar structures; relative displacement between the fixing device and the precast module is prone to occur during transportation; and the production process relies on manual operation and lacks intelligent management methods. These problems seriously affect the production efficiency and quality of PC components. For instance, utility model CN220763015U relates to a simple tooling for fixing molds during PC component production, including an L-shaped steel plate, a screw, and a nut. The L-shaped steel plate has a clamping part and a vertical part, with a through groove in the middle of the clamping part; one end of the screw is fixedly welded to the mold table, and the screw can pass through the through groove to connect with the nut. The screw and the nut together press the L-shaped steel plate and the precast composite slab mold frame, thereby restricting the movement of the precast composite slab mold frame. This utility model has a simple structure and low cost; however, its fixing method is singular and cannot provide effective fixing for complex-shaped or irregularly arranged steel reinforcement structures. Using screws and nuts to clamp the L-shaped steel plate 1 and the precast composite slab mold frame requires manual adjustment of the clamping force and position when dealing with steel reinforcement of different specifications and arrangements. This process is cumbersome and time-consuming, making it difficult to quickly adapt to the fixing needs of different steel reinforcements and severely impacting production efficiency. Therefore, it is necessary to develop an auxiliary fixing device for PC component production to address these shortcomings. Utility Model Content

[0022] Refer to the attached diagram. Figure 1 This is a three-dimensional structural diagram of the auxiliary fixing device for PC component production according to this utility model; Figure 2 for Figure 1 Explosion diagram at point A; Figure 3 This is a three-dimensional structural diagram of the front of the gripper assembly; Figure 4 This is a schematic diagram of the three-dimensional structure of the gripper assembly on the back.

[0023] In one specific implementation, such as Figures 1-4 As shown, an auxiliary fixing device for PC component production includes a frame. The frame is composed of L-shaped steel plates 1 forming a rectangle, with adjacent L-shaped steel plates 1 connected by quick-locking components 2. The rectangular frame, formed by splicing four L-shaped steel plates 1, can withstand significant external forces in both horizontal and vertical directions, providing a high strength and stability foundation for the entire auxiliary fixing device. Several clamping components 3 for clamping reinforcing bars are installed on the L-shaped steel plates 1. A waist-shaped groove 101 is provided on the horizontal folded edge of the L-shaped steel plate 1, and the clamping components 3 are detachably installed on the horizontal folded edge of the L-shaped steel plate 1 by bolts passing through the waist-shaped groove 101. Clamping components 3 are installed at corresponding positions according to the location of the reinforcing bars. A non-removable plate 5 is provided on the inner side of the vertical end of the L-shaped steel plate 1. The non-removable plates 5 are connected end-to-end and fixed within the area enclosed by the L-shaped steel plates 1. The non-removable plate 5 is a fiber-reinforced pressure plate with a galvanized steel mesh embedded in the middle. The reinforcing bars pass through the mesh and are clamped at both ends by the clamping components 3.

[0024] In one specific implementation, such as Figures 1-4As shown, the quick-locking assembly 2 includes a first angle iron 201 and a second angle iron 202. The upper end of the horizontal fold of the L-shaped steel plate 1 is provided with a slot 102, the bottom end of which is flush with the upper surface of the horizontal fold. The slot 102 is located at both ends of the L-shaped steel plate 1. The upper surface of the vertical step of the L-shaped steel plate 1 is provided with a square groove 103, located at both ends of adjacent L-shaped steel plates 1 and forming a connected area. When adjacent L-shaped steel plates 1 are spliced, the square groove 103 and the slot 102 cooperate spatially to achieve connection. The first angle iron 201 is horizontally inserted into the slot 102 and further fixed with bolts. The second angle iron 202 is vertically inserted into the square groove 103 and further fixed with bolts. Adjacent L-shaped steel plates 1 are connected through the first angle iron 201 and the second angle iron 202. This connection method is convenient to install and provides a firm connection, avoiding the instability of the frame structure caused by loose connections.

[0025] In one specific implementation, such as Figures 1-4 As shown, the clamping assembly 3 includes a fixed plate 301, an electric telescopic rod 302, and a gripper assembly 4. The fixed plate 301 is placed on the horizontal folded edge of the L-shaped steel plate 1. The fixed plate 301 has a circular hole, and bolts pass through the circular hole and the waist-shaped groove 101 to lock the fixed plate 301 onto the horizontal folded edge. The design of the waist-shaped groove 101 allows the clamping assembly 3 to move within a certain range in the horizontal direction to adapt to the clamping requirements of reinforcing bars at different positions. The electric telescopic rod 302 is fixed to the side of the fixed plate 301 away from the circular hole. The upper end of the electric telescopic rod 302 is fixedly connected to the gripper assembly 4, and the height of the gripper assembly 4 is adjusted by the electric telescopic rod 302. By adjusting the length of the extended end of the electric telescopic rod 302, the height of the gripper assembly 4 can be changed to adapt to the clamping requirements of reinforcing bars of different heights.

[0026] In one specific implementation, such as Figures 1-4 As shown, the gripper assembly 4 includes a mounting base 401, a gripping block 402, a motor 403, a drive rod 404, and a connecting rod 405. The mounting base 401 is vertically fixed to the upper end face of the electric telescopic rod 302. The upper end of the mounting base 401 is provided with a slide rail. The gripping block 402 has two parts that are slidably mounted on both ends of the slide rail through T-slots to achieve horizontal sliding and prevent disengagement. The motor 403 is mounted in the middle of the mounting base 401. The motor 403 is vertically arranged with the mounting base 401. The output end of the motor 403 passes through the mounting base 401 and is fixedly connected to the drive rod 404. The two ends of the drive rod 404 are respectively rotatably connected to the connecting rod 405. The lower end of the gripping block 402 extends downward and is provided with a support foot 4021. The support foot 4021 is located on the side close to the connecting rod 405. The other end of the connecting rod 405 is hinged to the adjacent gripping block 402 through the support foot 4021. When the motor 403 starts, the drive rod 404 rotates, which drives the connecting rod 405 to move, thereby causing the clamping block 402 to slide on the slide rail, realizing the clamping or releasing action.

[0027] In one specific implementation, such as Figures 1-4 As shown, the two clamping blocks 402 have several corresponding slots 4022 on their opposing surfaces. Each slot 4022 has a V-shaped opening, forming a clamping space between two slots 4022 on opposite surfaces for holding the reinforcing bar. The V-shaped opening angle is 60°, and the opening width matches the diameter of the reinforcing bar. Anti-slip pads are attached to the front end of each slot 4022. These pads increase friction when the reinforcing bar is being clamped in and out, resulting in better clamping. The V-shaped opening design allows the reinforcing bar to automatically center itself and better accommodates reinforcing bars of different diameters, resulting in a better clamping effect.

[0028] In one specific implementation, such as Figures 1-4 As shown, the square groove 103 is a tapered groove, which corresponds to the vertical end structure of the second angle iron 202. The square groove 103 adopts a tapered groove design, which can fit tightly with the vertical end of the second angle iron 202 to enhance the fastness and positioning accuracy when connecting adjacent L-shaped steel plates 1.

[0029] The operation process of this auxiliary fixing device for PC component production is as follows: Four L-shaped steel plates 1 are spliced ​​together according to the shape of a rectangular frame, and adjacent L-shaped steel plates 1 are connected and fixed using the quick-locking assembly 2. Specifically, the first angle iron 201 is horizontally inserted into the slot 102 and fixed with bolts, and the second angle iron 202 is vertically inserted into the square slot 103 and fixed with bolts to ensure the stability of the frame structure. According to the arrangement position and height of the reinforcing bars, the clamping assembly 3 is installed on the horizontal folded edge of the L-shaped steel plate 1 with bolts. The horizontal position of the clamping assembly 3 is adjusted by the waist-shaped slot 101, and the height of the clamping claw assembly 4 is adjusted by adjusting the electric telescopic rod 302 to achieve a suitable position. After the reinforcing bars are placed in the appropriate position, the motor 403 of the clamping assembly 3 is started. The motor 403 drives the drive rod 404 to rotate, and the connecting rods 405 at both ends of the drive rod 404 move accordingly, pushing the clamping blocks 402 to slide towards the middle on the slide rail, so that the V-shaped jaws 4022 on the two clamping blocks 402 gradually approach the reinforcing bars. As the clamping block 402 moves, the V-shaped jaw 4022 clamps the reinforcing bar. Due to the V-shaped opening design, the reinforcing bar can automatically center itself, and the clamping force is evenly distributed, firmly clamping the reinforcing bar and preventing displacement during production. During the production of PC components, this auxiliary fixing device maintains stable fixation of the reinforcing bar. Because the clamping assembly 3 can adapt to reinforcing bars of different specifications, arrangements, and heights, and its frame structure is stable and can withstand various external forces during production, the production quality of the PC components is guaranteed. When the auxiliary fixing device needs to be disassembled after production or transportation, first stop the motor 403 to allow the clamping block 402 to release the reinforcing bar. Then, loosen the bolts between the clamping assembly 3 and the L-shaped steel plate 1, and remove the clamping assembly 3 from the L-shaped steel plate 1. Finally, loosen the bolts of the quick-locking assembly 2, remove the first angle iron 201 and the second angle iron 202 from the slot 102 and square slot 103, separate the four L-shaped steel plates 1, and complete the disassembly of the device.

[0030] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. For the apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to the method section.

[0031] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
