[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figures 1 to 5 As shown, the utility model provides a precast concrete component installation and positioning structure, including a mobile frame 1, the top of the mobile frame 1 is fixedly connected to a top plate 2, the four corners of the top of the top plate 2 are fixedly connected to an electric cylinder 3, the output end of the electric cylinder 3 passes through the top of the top plate 2, the output end of the electric cylinder 3 is fixedly connected to a U-shaped plate 4, both sides of the inside of the U-shaped plate 4 are provided with splints 5, the top of the splint 5 is fixedly connected to a transmission block 6, the top of the transmission block 6 extends to the top of the U-shaped plate 4, the surface of the transmission block 6 is fixedly connected to a control mechanism 7, the four corners inside the U-shaped plate 4 are fixedly connected to a sliding rod 8, and the splint 5 is slidably connected to the surface of the sliding rod 8.

[0023] refer to Figure 3The control mechanism 7 includes a mounting frame 71, which is fixedly connected to the top of the U-shaped plate 4. The top of the U-shaped plate 4 is fixedly connected to a motor 72. The output end of the motor 72 passes through the interior of the mounting frame 71. The output end of the motor 72 is fixedly connected to a gear 73. The front and rear sides of the gear 73 are meshed with tooth plates 74. The outer side of the tooth plate 74 is fixedly connected to the surface of the transmission block 6.

[0024] As a technical optimization solution of the present invention, by providing a control mechanism 7 , the splint 5 can be controlled to avoid the splint 5 being unable to be manipulated during use, thereby improving the use efficiency of the splint 5 .

[0025] refer to Figure 5 The tooth plate 74 is internally slidably connected to the limiting block 9, and the bottom of the limiting block 9 is fixedly connected to the top of the U-shaped plate 4.

[0026] As a technical optimization solution of the present invention, by setting the limit block 9, the sliding of the tooth plate 74 can be stabilized to prevent the tooth plate 74 from shaking during the sliding movement, causing the tooth plate 74 to loosen, thereby improving the sliding stability of the tooth plate 74.

[0027] refer to Figure 3 The outer side of the tooth plate 74 is fixedly connected with a reinforcing plate 10 , and the surface of the reinforcing plate 10 is fixedly connected to the surface of the transmission block 6 .

[0028] As a technical optimization solution of the present invention, by setting a reinforcement plate 10, the connection between the tooth plate 74 and the transmission block 6 can be reinforced to avoid breakage of the tooth plate 74 and the transmission block 6 during use, prevent the tooth plate 74 and the transmission block 6 from failing to cooperate, and improve the use effect of the tooth plate 74 and the transmission block 6.

[0029] refer to Figure 3 A friction strip 11 is fixedly connected to the inner side of the splint 5 , and the friction strip 11 is located inside the U-shaped plate 4 .

[0030] As a technical optimization solution of the present invention, by setting the friction strip 11, the friction between the clamping plate 5 and the workpiece can be increased, avoiding the small friction between the clamping plate 5 and the workpiece, which causes the workpiece to slide on the inner side of the clamping plate 5, thereby improving the stability of the workpiece.

[0031] refer to Figure 2 The four corners of the top of the U-shaped plate 4 are fixedly connected with anti-collision blocks 12, and the anti-collision blocks 12 are located at the bottom of the top plate 2.

[0032] As a technical optimization solution of the present invention, by setting the anti-collision block 12, the U-shaped plate 4 can be protected to prevent the U-shaped plate 4 from colliding with the top plate 2 during movement, thereby preventing the U-shaped plate 4 from being damaged and improving the working safety of the U-shaped plate 4.

[0033] refer to Figure 4 The surface of the slide rod 8 is sleeved with a slide sleeve 13 , and the surface of the slide sleeve 13 is fixedly connected to the surface of the splint 5 .

[0034] As a technical optimization solution of the present invention, by providing the sliding sleeve 13, the sliding of the splint 5 can be stabilized, thereby preventing the splint 5 from shaking during the sliding movement, causing the splint 5 to loosen, and improving the sliding stability of the splint 5.

[0035] The working principle and usage process of the present invention are as follows: when in use, when the splint 5 needs to clamp the precast concrete component, the motor 72 is started, the motor 72 drives the gear 73 to rotate, the gear 73 drives the tooth plate 74 to move, the tooth plate 74 drives the transmission block 6 to move inward, and the transmission block 6 drives the splint 5 to move inward. When the splint 5 contacts the precast concrete component, the motor 72 is turned off. Since the transmission block 6 is short, it is difficult for the transmission block 6 to tilt with the splint 5. The splint 5 slides on the surface of the slide rod 8. The splint 5 cannot tilt, and the transmission block 6 cannot tilt, thereby having the advantage of high work safety.

[0036] To sum up: the precast concrete component installation and positioning structure, through the coordinated use of the mobile frame 1, the top plate 2, the electric cylinder 3, the U-shaped plate 4, the clamping plate 5, the transmission block 6 and the control mechanism 7, solves the problem that the clamping plate is driven by the slider. Due to the long length of the slider, when the clamping plate contacts the precast concrete component, the precast concrete component will block the movement of the clamping plate, and the end of the slider away from the clamping will continue to move slightly, causing the slider to tilt and bend. When the slider is like this for a long time, the structural strength of the slider will be reduced and damaged, thereby reducing the safety of the use of the precast concrete component installation and positioning structure.
