For further disclosure of the detailed structure of the automatic snapping mechanism 7. The installation shell comprises a bottom plate 71, the top surface of which is connected with two shell plates 72 through bolt locking, two opposite top baffle plates 73 and two opposite bottom baffle plates 75 are connected between the two shell plates 72 through bolt locking, the two top baffle plates 73 are positioned above the two bottom baffle plates 75, a channel is formed in a space between the two top baffle plates 73 and the two bottom baffle plates 75, an upper clearance groove 731 is formed between the two top baffle plates 73, an upper pressing block 74 is in sliding connection with the upper clearance groove 731, the upper pressing block 74 slides along the vertical direction, and a first chain tooth groove 741 is matched with the top surface of a chain 16 positioned in the automatic engagement mechanism 7. A lower clearance groove 751 is formed between the two bottom baffles 75, the lower pressing block 76 is slidably connected with the lower clearance groove 751, the lower pressing block 76 slides along the vertical direction, the lower pressing block 76 and the upper pressing block 74 are opposite, and the second chain tooth slot 761 is matched with the bottom surface of the chain 16 positioned in the automatic meshing mechanism 7.

The engagement driving member includes a control motor 77 connected to the top surface of the bottom plate 71, the control motor 77 is located outside the two housing plates 72, the top surface of the bottom plate 71 is rotatably connected with a first gear 771 and a second gear 78 which are meshed with each other through a rotating shaft and a bearing, the first gear 771 rotates coaxially with a driving shaft of the control motor 77, the second gear 78 rotates coaxially with a driving rod 781, the driving rod 781 extends into the lower clearance groove 751 and the upper clearance groove 731, both ends of the driving rod 781 are respectively provided with a first threaded portion 782 and a second threaded portion 783 which are opposite in screwing direction, the first threaded portion 782 is located at one side close to the bottom plate 71, the driving rod 781 is threaded through the lower pressing block 76 through the first threaded portion 782, and the driving rod 781 is threaded through the upper pressing block 74 through the second threaded portion 783.

Specifically, since the upper press block 74 is slidably engaged in the upper clearance groove 731 and the lower clearance groove 751 of the lower press block 76 is slidably engaged, the rotation of the upper press block 74 and the lower press block 76 with respect to the transmission rod 781 can be reduced, and simultaneously, the first gear 771 is driven to rotate under the driving action of the control motor 77 due to the opposite rotation directions of the threads of the first threaded portion 782 and the second threaded portion 783 of the transmission rod 781, and the second gear 78 is driven to rotate by the transmission, so that the upper press block 74 and the lower press block 76 are driven by the threads of the second threaded portion 783 and the first threaded portion 782, respectively, thereby realizing the function of moving in opposite or opposite directions. The upper pressing block 74 and the lower pressing block 76 move towards the opposite directions, the first sprocket groove 741 of the upper pressing block 74 is in plug-in fit with the top surface of the opposite chain 16, and meanwhile, when the second sprocket groove 761 of the lower pressing block 76 is in plug-in fit with the bottom surface of the opposite chain 16, the chain 16 is engaged, so that the synchronous movement function of the automatic engagement mechanism 7 and the chain 16 is realized. Conversely, when the upper press block 74 and the lower press block 76 move in opposite directions, the function of disengaging the chain 16 and thus disengaging the automatic engagement mechanism 7 from the synchronous movement of the chain 16 can be achieved.

Based on the above-described structure disclosed with respect to the automatic engagement mechanism 7, since the upper press block 74 and the lower press block 76 mainly rely on rotation limitation in sliding connection therewith and simultaneously realize relative or opposite movement under the transmission action of the threaded portion of the transmission rod 781, the upper press block 74 and the lower press block 76 also need to overcome the condition of surface contact limitation during up-and-down movement, and thus there is a possibility that movement is blocked or parts are worn out to degrade engagement accuracy. In order to solve this problem, the stability of the relative or opposite movement of the upper press block 74 and the lower press block 76 is achieved, while the service life of the automatic engagement mechanism 7 is improved. The bottom surface of bottom plate 71 is connected with third gear 79 through pivot and bearing rotation, third gear 79 is located one side that second gear 78 kept away from first gear 771, and third gear 79 meshes with second gear 78, the coaxial rotation of third gear 79 has gangbar 791, gangbar 791 stretches into lower clearance groove 751 and go up clearance groove 731, the both ends of gangbar 791 are provided with third screw thread portion 792 and fourth screw thread portion 793 that the screw thread is opposite in direction respectively, third screw thread portion 792 is located one side that is close to bottom plate 71, and the screw thread of third screw thread portion 792 and second screw thread portion 783 is also opposite in direction, gangbar 791 is through lower briquetting 76 through the screw thread of third screw thread portion 792, gangbar 791 is through upper briquetting 74 through the screw thread of fourth screw thread portion 793.

Specifically, due to the fact that the gears are meshed in a transmission manner, the rotation directions of the second gear 78 and the third gear 79 are opposite, meanwhile, due to the fact that the rotation directions of the first thread part 782 and the third thread part 792 are opposite, the rotation directions of the second thread part 783 and the fourth thread part 793 are opposite, and therefore under the driving action of the control motor 77, the transmission rod 781 and the linkage rod 791 are driven to rotate, and under the synchronous driving action of the first thread part 782 and the third thread part 792, the function of stably moving up or down the lower pressing block 76 is achieved, and the upper pressing block 74 can also stably move up or down under the synchronous driving action of the second thread part 783 and the fourth thread. The limit of the upward or downward movement of the upper and lower pressing blocks 74 and 76 depending on the sliding inner wall thereof can be reduced, thereby achieving the beneficial effects of reducing the limit resistance caused by the surface contact friction, and improving the movement stability and the service life.

Further, a lifting trolley 8 is arranged at the bottom of the main arm 1 through a chain transmission mechanism so as to hoist the prefabricated component, and in the process, the chain transmission mechanism drives the two movable door type supports 6 to move to one side far away from the lifting trolley 8 so as to temporarily anchor the prefabricated component, and further the prefabricated component lifted by the lifting trolley 8 is conveniently weighted. It should be noted that, when two door-type movable brackets are used for counterweight, the anti-overturning capability of the slewing mechanism 2 needs to be considered: when the moment difference between the moment generated by the two movable gate brackets 6 at the end on the swing mechanism 2 and the moment generated by the prefabricated member lifted by the trolley 8 on the swing mechanism 2 is within the anti-overturning capacity range of the swing mechanism 2, the movable gate brackets 6 can be anchored at the end of the main arm 1 all the time in the counterweight process.
