Description

Technical Field

[0001] The utility model belongs to the technical field of crane equipment, in particular to a truck-mounted crane for building wall panels. Background Art

[0002] Truck-mounted cranes in my country are currently in the development stage, with relatively few varieties. Currently, they are primarily categorized into straight-arm and folding-arm types, depending on their structural form. The folding-arm structure is a common structure for truck-mounted cranes. The mechanical structure of a folding-arm crane primarily includes the base assembly, slewing drive, column, boom assembly, boom assembly, and hook assembly. The hydraulic system primarily includes the boom cylinder, boom cylinder, telescopic cylinder, slewing motor, hydraulic winch, electro-hydraulic proportional reversing valve, and counterbalance valve. The boom assembly, boom assembly, boom cylinder, and boom cylinder together constitute the crane's luffing mechanism.

[0003] The slewing motion of a truck-mounted crane is achieved by a slewing mechanism. Traditionally, there are two types of slewing mechanisms: 1. A reducer and slewing bearing structure; 2. A rack cylinder and pinion column structure. Their characteristics include: 1. Complex structures, requiring numerous parts, making slewing mechanism problems more common and difficult to provide after-sales service. 2. High manufacturing and operating costs.

A third placement groove 29 is provided on the inner side of the bottom of the hook 26. A limit groove 30 is provided near the opening of the hook 26. The connector 28 is fixedly mounted on the lower end of the mounting plate 25. One end of the limit stop 27 is rotatably connected to the connecting piece 28, and the other end of the limit stop 27 is located at the limit groove 30; the setting of the hook assembly 24 is mainly used to hang the rope for fixing the building wall panel; during the hanging process, the rope is directly placed from the opening between the hook 26 and the mounting plate 25 into the third placement groove 29 of the hook 26, and the rope is constrained inside the hook 26 through the cooperation between the limit stop 27 and the limit groove 30, which can effectively prevent the rope from falling off the hook 26 during the lifting and rotation process of the crane, thereby causing a safety accident.

[0048] The working principle and use process of this utility model:

[0049] When using the device to lift a building wall panel, first hang the rope of the fixing device wall panel on the hook 26, and then lift the building wall panel through the crane arm 12; the length of the cable 23 can be controlled by the cable retracting device 22, and the inclination angle of the crane arm 12 can be adjusted by the jack 18. The driving motor 6 drives the driving gear 7 to rotate. Since the driving gear 7 is meshed with the driven gear 10, the driven gear 10 rotates with the rotation of the driving gear 7, thereby driving the placement plate 8 to rotate, thereby driving the crane arm 12 to rotate, and realizing the rotation of the crane arm 12.
