The gripping and clamping mechanism 31 has a lifting part for gripping a point to be lifted and a lifting driving mechanism for driving the lifting part to lift, and the lifting part may be a claw or a hook or a clamping jaw. The stability of lifting and demoulding is ensured. It is to be understood that the configurations of the traveling unit 32, the lifting unit, and the power unit 4 are not limited to a large number of configurations, and the same effects can be ensured.

In addition, the prefabricated part 5 generally needs to stretch the reinforcement cage pre-embedded in the prefabricated part to enable the reinforcement cage to have prestress, so that the load-resisting strength of the prefabricated part 5 is improved. Therefore, before demoulding, the two ends of the prefabricated part 5 are usually connected with the tensioning structures, when the prefabricated part 5 is lifted, the lifting positions on the suspension beam 3 can be moved to the tensioning structures of which the two ends of the prefabricated part 5 are not completely removed, the tensioning structures are used as lifting points, when the stress of each lifting point of the prefabricated part 5 is unbalanced, one parallelism of the prefabricated part 5 is adjusted by matching with the lifting points pre-embedded in the prefabricated part 5, the multi-point lifting of the prefabricated part 5 is ensured, and therefore smooth demoulding of the prefabricated part 5 and the mould 7 is achieved.

Further, as shown in fig. 1, in this embodiment, the tensioning structures at two end portions of the prefabricated component 5 are tensioning pieces 52, that is, the tensioning pieces 52 capable of being disassembled are disposed at two end portions of the prefabricated component 5, the embedded pieces 51 are embedded in the prefabricated component 5 in advance, and both the tensioning pieces 52 and the embedded pieces 51 can be used as points to be lifted in the above structure.

Specifically, bury in built-in fitting 51 of prefabricated component 5 intermediate position department in advance can be rings or lifting hook or buried nut in advance, because rings, lifting hook and buried nut in advance itself have small characteristics for the installation of built-in fitting 51 is more convenient, can not cause too big influence to prefabricated component 5 structure and anti load strength simultaneously.

As shown in fig. 1, in this embodiment, the walking frame 1 is mainly composed of a cross beam 11 and supporting legs 12, one end of the cross beam 11 is fixedly connected with one end of the supporting legs 12, so as to ensure the overall stability of the whole walking frame 1, and the limiting blocks 6 are further disposed at two ends of the cross beam 11 connected with the supporting legs 12, so as to mainly prevent the hoisting mechanism 2 from departing from the effective length range of the cross beam 11, wherein the bottom of the supporting legs 12 is further provided with a walking mechanism 121, so as to hoist the prefabricated components 5 at different positions, improve the hoisting efficiency, and ensure the universality of the hoisting mechanism. The mentioned traveling mechanism 121 may be a roller or a wheel or a pulley and rail combination or a slider and rail combination, and the two ends of the prefabricated part 5 are provided with corresponding rails, the rails are as far away from the prefabricated part 5 as possible so as not to affect the production of the prefabricated part 5, and a distance for the traveling of the traveling frame 1 is left between the rails and the prefabricated part 5. The hoisting mechanism 2 on the beam 11 includes a winding drum 21, a traction device 22 and a driving device 24, the driving device 24 is in transmission connection with the winding drum 21 through a driving shaft, so that the driving device 24 drives the winding drum 21 to rotate around the axis of the driving shaft, as shown in fig. 1, one end of the traction device 22 is wound on the outer wall of the winding drum 21, the other end is fixedly connected with the suspension beam 3, the traction device 22 can extend and retract along with the rotation of the winding drum 21 so as to control the suspension beam 3 to lift, so as to adjust the distance between a gripping mechanism 31 on the suspension beam 3 and the prefabricated part 5, wherein the gripping mechanism 31 grips a point to be lifted on the prefabricated part 5. According to the structure design, the structure is simple, the reliability is high, and the hoisting of the prefabricated part 5 is more convenient. Meanwhile, a brake 23 is arranged at the position where the driving shaft of the driving device 24 is in transmission connection with the winding drum 21, and the brake 23 can be used for timely braking and stopping in case of emergency in the process of hoisting the prefabricated part 5, so that the operation safety is ensured.

As can be seen from the above structure, in the present embodiment, the pulling device 22 for pulling the suspension beam 3 is a rope or a chain, and is characterized by being conveniently wound on the winding drum 21 of the hoisting mechanism 2, wherein the gripping mechanism 31 is a claw, a hook or a claw for gripping an embedded part 51 with a hooking part, such as a hanging ring. And the driving device 24 in charge of the power system of the whole hoisting mechanism 2 is a driving motor or a driving oil cylinder and the like, so that the whole hoisting mechanism for hoisting the prefabricated part 5 has more guaranteed power output. Of course, the above-described structural design is not limited to only the above-described several configurations.

In this embodiment, two ends of the winding drum 21 on the winding mechanism 2 extend outward to form transmission shafts, and at least one of the transmission shafts is in transmission connection with a driving shaft on the driving device 24, and each driving device 24 is further electrically connected with a control switch. As shown in fig. 1, the driving devices 24 are provided with control switches, so that the driving devices 24 can be controlled individually, when the prefabricated part 5 is lifted by the crane due to an external reason, the suspension beam 3 has a high end and a low end, that is, the lifting points are different, so that the two ends of the prefabricated part 5 are not in the same horizontal line, that is, the control switches control the corresponding driving devices 24 to adjust the height, so that the suspension beam 3 recovers the horizontal height, thereby facilitating multi-point lifting of the prefabricated part 5 and improving the stability of the prefabricated part 5 in the lifting process. The outer diameters of all the winding drums 21 arranged on the winding mechanisms 2 are the same, and the traction devices 22 wound on the outer walls of the winding drums 21 are always at the same horizontal height in the lifting process, so that the situation that the lengths of the traction devices 22 are different due to different outer diameters of the winding drums 21 is avoided, and the prefabricated parts 5 are inclined in the lifting process and damage to the lifting mechanisms is caused.

As shown in fig. 2, in the present embodiment, the cross beam 11 on the traveling frame 1 is plate-shaped or frame-shaped, and if the cross beam is plate-shaped, the middle portion of the cross beam 11 penetrates in the vertical direction, and the main purpose of the cross beam is to ensure that the traction device 22 can smoothly pass through the cross beam 11 to drive the suspension beam 3 to perform an elevating motion, so as to control the gripping mechanism 31 to smoothly grip the point to be lifted on the prefabricated part 5. Due to the above structural design, when the traction device 22 passes through the cross beam 11 to control the gripping mechanism 31 to lift the prefabricated part 5, the abrasion of the traction device 22 is reduced, and because the prefabricated part 5 has a large weight, if the traction device 22 is in contact with the cross beam 11 to lift the prefabricated part 5, after a period of time, the traction device 22 and the cross beam 11 are seriously abraded, and more seriously, the traction device 22 is broken, so that a great safety problem and loss are caused.

According to the structure, the automatic identification sensor is arranged on the gripping mechanism 31, and the marker for identifying the automatic identification sensor is arranged on the point to be hung. Like structural design for when grabbing the clamp to waiting on prefabricated component 5, grab clamp mechanism 31 can go to the automation through the automatic identification inductor and seek the position of waiting to hang the point, carries out operation on next step afterwards, thereby has reduced artificial operation, makes lifting by crane of prefabricated component 5 laborsaving convenient more. The automatic identification sensor disposed on the gripping mechanism 31 is an infrared identification sensor or a magnetic identification sensor, and similarly, the marker disposed on the point to be lifted is also adjusted, and may be a substance for infrared scanning or some metal substance for magnetic sensor identification. Of course, the automatic recognition sensor provided on the gripping mechanism 31 and the marker provided on the point to be lifted for recognition by the automatic recognition sensor are not limited to the above-described structures.

Various other modifications and changes may be made by those skilled in the art based on the above-described technical solutions and concepts, and all such modifications and changes are intended to fall within the scope of the claims.
