Description

Technical Field

[0001] The utility model belongs to the field of building prefabricated component production equipment, and particularly relates to a clamping claw and truss reinforcement grabbing device. Background Art

[0002] Precast concrete parts are concrete components processed in prefabrication plants or construction sites for use in building assembly. Using precast concrete components to construct prefabricated buildings can improve the degree of factory and mechanized construction, save on-site labor, and shorten the construction period.

[0003] During the production of precast composite panels, truss reinforcement is incorporated to save steel and increase shear resistance. Composed of bottom and top chords, as well as connecting bars, these reinforcements are heavy, requiring manual handling, which would be labor-intensive and reduce processing efficiency. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a clamping claw and a truss bar grabbing device, which can realize the grabbing and transferring of the truss bars.

[0005] The technical solution adopted in this utility model is:

[0006] A clamping jaw includes a mounting base, a fixed plate fixedly arranged on the mounting base, a clamping arm with one end arranged on the fixed plate through a rotating shaft, a driving arm rotatably arranged on the mounting base, and a spring arranged between the driving arm and the clamping arm. The driving arm deflects under the drive of its driving device, thereby driving the clamping arm to deflect.

[0007] Furthermore, a plurality of connection holes for connecting with springs are provided on the clamping arm.

[0008] Furthermore, the mounting seat is arranged on the base, and a cylinder is provided on the base. The driving arm extends out of one side of the fixed disk, the cylinder body of the cylinder is mounted on the base through a rotating shaft, and the piston rod is connected to one end of the driving arm extending out of the fixed disk through a rotating shaft.

[0009] Furthermore, a limiting device is provided between the fixed plate and the clamping arm, and the limiting device includes a limiting plate A fixedly set on the fixed plate, a limiting plate B set on the clamping arm, and a limiting nut set on the limiting plate A. A threaded hole is provided on the limiting plate A, and the limiting nut is installed in the threaded hole, with its end resting on the limiting plate B.

[0010] A truss bar grabbing device comprises a main frame, a traveling vehicle arranged on the main frame, a lifting frame arranged on the traveling vehicle, a grabbing mounting frame arranged on the lifting frame, and a clamping claw arranged on the grabbing mounting frame.

[0011] Furthermore, the grabbing mounting frame includes a plurality of mounting rod groups arranged in parallel, each mounting rod group includes two mounting rods, and a plurality of clamping claws are arranged on the mounting rods in opposite directions.

[0012] Furthermore, the base of the clamping jaw is fixedly connected to the mounting rod.

[0013] Furthermore, the grabbing and mounting frame further comprises a plurality of fixing rods, which are fixedly connected to the mounting rods so that the grabbing and mounting frame forms a frame structure.

[0014] The positive effects of this utility model are:

[0015] The gripper of this utility model utilizes a drive device to pull a spring to deflect the gripper arm, thereby achieving the gripping action of the object. The spring has a certain elastic force, forming a certain buffering effect. If something blocks the gripping process, the gripper arm will stop moving, without causing damage to the drive device or the gripped object. It can also adapt to the gripping action of objects of different sizes within a certain range. At the same time, when multiple grippers are working simultaneously, the cessation of one gripper will not affect the overall gripping effect.

[0016] The truss bar grabbing device utilizes the characteristics of the clamping claw to achieve the effect of being basically compatible with truss bars of all sizes. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Figure 3 This is a structural diagram of the grabbing and mounting frame of the utility model. DETAILED DESCRIPTION

[0020] Example 1

[0021] As attached Figure 1 As shown, this embodiment provides a clamping claw, comprising a base 1, a mounting base 2 disposed on the base 1, a fixed disk 3 fixedly disposed on the mounting base 2, a clamping arm 4 disposed on the fixed disk 3 at one end via a rotating shaft, a driving arm 5 rotatably disposed on the mounting base 2, and a spring 6 disposed between the driving arm 5 and the clamping arm 4. The rotating shaft between the clamping arm 4 and the fixed disk 3 is disposed at a lower position of the fixed disk 3 so that the clamping arm 4 does not affect the operation of other components during the deflection process. One end of the driving arm 5 is rotatably disposed at the axial center position of the fixed disk 3 and can be deflected under the drive of a driving device. During the deflection process, the spring 6 is driven to move, thereby driving the clamping arm 4 to deflect and perform a clamping action.

[0022] Preferably, one end of the driving arm 5 extends beyond the fixed plate 3. A cylinder 8 is mounted on the base 1 to act as a driving device. The cylinder body of the cylinder 8 is mounted on the base 1 via a rotating shaft. The piston rod is connected to the end of the driving arm 5 that extends beyond the fixed plate 3. The driving arm 5 extending beyond the fixed plate 3 acts as a lever, reducing the force required to apply to the driving device. The cylinder 8 is only a solution for this embodiment and can also be replaced with an electric telescopic rod, etc.

[0023] On the clamp arm 4, several connecting holes 7 for connecting with the spring 6 are set along the length direction of the clamp arm 4. One end of the spring 6 is connected to the connecting hole 7 through a nut or other structure. The connecting hole 7 is selected according to actual conditions, which can be used to relieve spring fatigue.

[0024] There is also a limiting device between the fixed plate 3 and the clamping arm 4, which includes a limiting plate A9 fixed on the fixed plate 3, a limiting plate B arranged on the clamping arm 4, and a limiting nut 10 arranged between the two limiting plates. A threaded hole is provided on the limiting plate A9, and the limiting nut 10 is installed in the threaded hole, one end of which rests on the limiting plate B. By adjusting the end position of the limiting nut 10, the clamping arm 4 is limited.

[0025] The clamping claw of this embodiment uses a spring 6 to drive its rotation. Compared with the traditional direct drive method using a cylinder, the spring 6 can play a certain buffering role. If the clamping arm 4 hits an object during the clamping process, it can stop at any time, and can realize the clamping action of objects of various sizes. At the same time, it can prevent damage to objects due to the failure of the driving device to stop in time.

[0026] Example 2

[0027] This embodiment provides a truss bar grabbing device, as shown in the attached Figure 2 、 3 As shown, it includes a large frame 11, a traveling vehicle 12 arranged on the large frame 11, a lifting frame 13 arranged on the traveling vehicle 12, a grabbing mounting frame arranged on the lifting frame 13, and a clamping claw arranged on the grabbing mounting frame.

[0028] The grabbing and mounting frame comprises several parallel mounting rod groups 15 and several fixed rods 14 disposed between the mounting rod groups 15, forming a frame-like structure. Each mounting rod group 15 includes two mounting rods, each of which is provided with a plurality of opposing clamping jaws. The base 1 in the clamping jaws is fixedly connected to the fixed rod.

[0029] The grippers on each mounting rod assembly 15 grasp one truss bar. Multiple mounting rod assemblies 15 can simultaneously grasp a stacked layer of truss bars, increasing grasping efficiency. The lifting frame 13 acts as a lifting mechanism, while the main frame 11 and traveler 12 act as a translation mechanism to achieve grasping and moving the truss bars. The springs 6 on the grippers act as a buffer, allowing them to grasp truss bars within a certain size range. This allows them to accommodate truss bars of virtually all sizes and prevent them from entering the molds on the production line.
