Abstract
Description
Technical Field

[0002] The technology of concrete precast blocks, as a key part of building industrialization, prefabricates concrete components through factory production methods to improve the construction efficiency and quality of buildings. The production of precast blocks involves links such as design, mold preparation, material preparation, concrete pouring, curing, and quality inspection, ensuring the standardization and consistency of components. At the construction site, precast blocks are quickly installed and firmly connected, reducing on-site operations, lowering costs, and being beneficial to environmental protection. Concrete precast blocks are widely used in building structures and infrastructure, promoting the transformation of the construction industry towards modernization, standardization, and greening.
[0003] Existing concrete precast blocks are generally transported by handling devices to save manpower and improve the transportation efficiency. During transportation, the precast blocks are clamped and fixed to prevent loosening. For example, Chinese Patent Publication No. CN210854299U discloses "a handling device for concrete precast blocks", in which two pulleys are rotatably installed on the clamping seat, a traction rope is slidably installed on the pulleys, one end of the traction rope is fixedly connected to the corresponding connecting block, and the other end of the traction rope extends below the clamping seat and is fixedly connected to the corresponding shovel plate. The two clamping seats slide towards each other, and the two clamping seats drive the two shovel plates to shovel up the materials respectively. When the first cylinder is started, the piston rod of the first cylinder drives the transmission plate to move slightly upward to lift the materials, thus facilitating the handling of the materials.
[0004] However, in actual use, due to the rough surface and large weight of concrete precast blocks, the clamping part of the handling device is easily worn, especially the part directly in contact with the concrete precast blocks, and the wear speed is faster, reducing the service life of the handling device. Moreover, it is not convenient to replace the clamping part, which affects the use effect. Content of the Utility Model

Specific implementation mode
[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.
[0024] Refer to Figures 1-5 , a concrete precast block handling device, including a support 1 and a clamping assembly 2. A moving mechanism 3 is arranged on the support 1, a lifting mechanism 4 is arranged on the moving mechanism 3, the clamping assembly 2 is arranged at the output end of the lifting mechanism 4, the clamping assembly 2 includes two moving parts 21, two jaws 22 are arranged on each moving part 21, and the jaws 22 are connected to the moving parts 21 through a connecting structure 23;
[0025] The connecting structure 23 includes an inserting part 231, a convex part 232 is arranged on the inserting part 231, the inserting part 231 is inserted into the moving part 21, and the convex part 232 is clamped with the moving part 21.
[0026] In the present utility model, the clamping assembly 2 is controlled by the lifting mechanism 4 to move up and down to clamp the concrete precast block, which is convenient for the moving mechanism 3 to drive the clamping assembly 2 to move and carry the concrete precast block. Moreover, the jaws 22 are connected to the moving parts 21 through the connecting structure 23, and the jaws 22 can be replaced, thereby prolonging the service life of the handling device.
[0027] Further, in this embodiment, a chute matching with the convex portion 232 is formed in the insertion portion 231, a limiting groove matching with the convex portion 232 is formed in the moving portion 21, and an adjusting structure 5 for controlling the position of the convex portion 232 is further arranged in the chute. The position of the convex portion 232 is controlled by the adjusting structure 5 to insert or release the insertion of the moving portion 21, so as to fix and release the fixing of the clamping jaw 22.
[0028] Furthermore, in this embodiment, the adjusting structure 5 includes a cam 51 rotatably arranged in the chute. Two convex portions 232 are slidably arranged in the chute. The protruding portions of the cam 51 can be in contact with the two convex portions 232 at the same time. The cam 51 is of an elliptical structure, and contact grooves are formed on both sides of the protruding portions. When the cam 51 rotates to make the protruding portions contact with the convex portion 232, the contact grooves contact with the convex portion 232. The contact grooves are of a planar structure, and the cam 51 is stuck and cannot rotate.
[0029] It should be noted that, in this embodiment, a mounting plate 233 is fixedly arranged in the chute. Pulling springs 234 are fixedly arranged on both sides of the mounting plate 233. The other ends of the two pulling springs 234 are respectively fixedly connected with the two convex portions 232. When the clamping jaw needs to be replaced, the cam 51 is rotated to separate its contact grooves and protruding portions from the convex portion 232, and the convex portion 232 is no longer extruded. Under the action of the pulling spring 234, the convex portion 232 is pulled into the chute, so that the insertion portion 231 and the clamping jaw 22 can be taken out for replacement.
[0030] In addition, in this embodiment, a rotating shaft 52 is fixedly arranged on the cam 51. The upper end of the rotating shaft 52 penetrates through the chute and is fixedly connected with a rotating portion 53. The rotating portion 53 and the rotating shaft 52 cooperate to form a labor-saving lever, which is convenient for rotating the cam 51 to control the position of the convex portion 232.
[0031] Specifically, in some embodiments, the clamping assembly 2 further includes a fixing plate 24 fixedly arranged at the output end of the lifting mechanism 4. A cylinder 25 is fixedly arranged on the fixing plate 24. The output shaft of the cylinder 25 is connected with the moving portion 21. A guide rail slidably connected with the moving portion 21 is fixedly arranged on the fixing plate 24. The position of the moving portion 21 is restricted by the guide rail. In some embodiments, the cylinder 25 can adopt other linear reciprocating devices such as a linear motor.
[0032] Working mode: During work, the clamping assembly 2 is controlled by the lifting mechanism 4 to move up and down to clamp the concrete precast block, which is convenient for the moving mechanism 3 to drive the clamping assembly 2 to move and carry the concrete precast block.
[0033] By rotating the rotating part 53, the rotating shaft 52 and the cam 51 are driven to rotate, so that the protruding part is separated from the protruding part 232 and no longer presses the protruding part 232. Under the action of the tension spring 234, the protruding part 232 is pulled into the sliding groove, so that the plugging part 231 and the clamping jaw 22 can be taken out for replacement.
[0034] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
