Description

Technical Field

[0001] The utility model belongs to the field of building prefabrication production equipment, and particularly relates to a finished product offline device for fine aggregate concrete precast components. Background Art

[0002] Concrete precast components are concrete components processed and manufactured in prefabrication factories or construction sites for building assembly. The use of precast concrete components to build prefabricated buildings can improve the degree of factory and mechanized construction, save on-site labor, and shorten the building construction period.

[0003] Precast components are generally processed and formed in molds. After processing, they need to be transferred offline to the storage location, which requires the use of a finished product offline device. For example, the utility model patent with the publication number CN211643847U discloses a precast component offline manipulator, which uses vacuum suction cups to adsorb components and uses hooks on both sides of the components for fixation. The hooks are driven by a lead screw mechanism. This technical solution uses both suction cups and hooks to grasp components. However, since not all components are smooth planes, the suction cups cannot adsorb all types of components, making it difficult to achieve universality. Moreover, this structure can only grasp components of specific sizes. When there is an obstruction at the hook position, the hook will be damaged under the drive of the lead screw. Summary of the Utility Model

The clamping device includes a mounting frame and a plurality of clamping jaws arranged on the mounting frame. The clamping jaws are arranged in pairs and there are several pairs arranged along the mounting frame.

[0007] Further, a plurality of chutes are arranged on the mounting frame, and connecting plates are arranged on the clamping jaws. The connecting plates are installed in the chutes through locking nuts.

[0019] As shown in the attached Figures 1-4As shown in the figure, the present utility model provides a finished product offline device for fine aggregate concrete precast components, which includes a large frame 11, a walking frame 15 arranged on the large frame 11, a lifting device 12 arranged on the walking frame 15, a clamping device installed on the lifting device, and a blanking trolley 14 arranged below the large frame 11 for transporting finished products. The large frame 11 serves as the installation frame of the entire mechanism, and a track is provided at its top, enabling the walking frame 15 to move horizontally along its track. The lifting device is located on the walking frame 15 and can move with it. At the same time, the lifting device can drive the clamping device to move up and down. There are two blanking trolleys 14, which are arranged side by side. Two stacks can be placed on each blanking trolley 14. The two blanking trolleys 14 transport finished products alternately, which can greatly improve the offline speed of finished products and improve the offline efficiency. The functions of the walking frame 15 and the lifting device 12 are simple and are more reflected in the prior art, so they will not be elaborated here.

[0020] The clamping device includes a mounting frame 13 connected to the lifting device and several pairs of clamping jaws arranged on the mounting frame 13. The clamping jaws are arranged in pairs and several pairs are arranged along the length direction of the mounting frame 13. The number of clamping jaws can be determined according to the actual components. If the component is lighter in weight, fewer clamping jaws can be selected; if it is heavier, the number of clamping jaws can be increased correspondingly. At the same time, several chutes 16 are provided on the mounting frame 13. A connecting plate 17 is fixedly installed on the clamping jaw. The connecting plate 17 is installed in the chute 16 through a locking nut. The installation position of the clamping jaw in the chute 16 can be adjusted through the locking nut, so as to adjust the distance between adjacent pairs of clamping jaws.

[0021] The clamping jaw includes a base 1, a mounting seat 2 arranged on the base 1, a fixed disk 3 fixedly arranged on the mounting seat 2, a clamping arm 4 with one end arranged on the fixed disk 3 through a rotating shaft, a driving arm 5 rotatably arranged on the mounting seat 2, and a spring 6 arranged between the driving arm 5 and the clamping arm 4. The connecting plate 17 can be fixedly arranged on one side of the mounting seat 2. The rotating shaft between the clamping arm 4 and the fixed disk 3 is arranged at a lower position of the fixed disk 3, so that the clamping arm 4 will not affect the operation of other components during the deflection process. One end of the driving arm 5 is rotatably arranged at the center position of the fixed disk 3 and can be deflected under the drive of the driving device. During the deflection process, the spring 6 is driven to move, so as to drive the clamping arm 4 to deflect for clamping action.

[0022] Preferably, one end of the driving arm 5 extends out of the fixed disk 3. A cylinder 8 seat is installed on the base 1 as the driving device. The cylinder body of the cylinder 8 is installed on the base 1 through a rotating shaft, and the piston rod is connected to one end of the driving arm 5 extending out of the fixed disk 3. One side of the driving arm 5 extending out of the fixed disk 3 can play the role of a lever, reducing the force application requirement for the driving device. The cylinder 8 is only the solution of this embodiment and can also be replaced with an electric telescopic rod, etc.

[0023] On the clamping arm 4, a number of connecting holes 7 for connecting with the spring 6 are arranged along the length direction of the clamping arm 4. One end of the spring 6 is connected to the connecting hole 7 through structures such as nuts. The connecting hole 7 can be selected according to the actual situation, which can be used to relieve spring fatigue.

[0024] There is also a limiting device between the fixed disk 3 and the clamping arm 4. The limiting device includes a limiting plate A9 fixed on the fixed disk 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 fitted and installed in the threaded hole, with one end abutted against the limiting plate B. By adjusting the end position of the limiting nut 10, the limitation of the clamping arm 4 can be realized.

[0025] The clamping jaw is driven to rotate by the spring 6. Compared with the traditional direct driving method using a cylinder, the spring 6 can play a certain buffering role. During the clamping process, if an object is encountered, the clamping arm 4 can stop at any time, which can prevent the clamping jaw or the article from being damaged due to the untimely stop of the driving device.

[0026] When the present utility model is in use, the clamping device grabs the fabricated component from the production line. The lifting device 12 descends to the grabbing position, the clamping device grabs the component, then performs a lifting and translation action, and positions it on the blanking trolley 14. The blanking trolley 14 transports the component to the next station to realize the offline of the finished product.

[0027] The above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: it is still possible to modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
