Description

Technical Field

[0001] The utility model relates to the technical field of crane equipment, in particular to a small vehicle-mounted crane. Background Art

[0002] Truck-mounted crane is a type of crane that is installed on vehicles such as cars and tractors. This type of crane is highly mobile and convenient, and can quickly reach the construction site, effectively ensuring the progress of the project.

[0003] For example, the Chinese utility model patent disclosed by publication number CN219603116U: a vehicle-mounted small crane, the application fixes the base to the car body of the construction vehicle by bolts, which is not only convenient to carry and use, but also greatly reduces safety hazards and saves labor costs. However, the application is fixed in the car body by bolts during installation. First of all, when the application is in use, since the connection between the base and the car body only relies on multiple bolts, when hoisting objects, the objects will exert a pulling force on the base, which can easily loosen the base from the car body board at the bottom of the car body. In addition, when hoisting objects through the application, a good supporting condition is not provided for the crane, which may cause the crane to lose balance due to shaking or instability of the car body when hoisting objects, increasing the risk of overturning.

With the arrangement of the protective shell 14, the piston end 10 can be protected. Two fixing plates 15 are fixedly installed on the lower end of the protective shell 14. A plurality of tooth blocks 16 are fixedly installed on the opposite sides of the two fixing plates 15.

[0022] like Figure 2-Figure 4As shown, both ends of the two connecting hoops 13 are fixedly installed with first fixing seats 17, the two connecting hoops 13 are respectively inserted and installed on the outside of the piston end 10, and a connecting bolt 18 is inserted and connected between two adjacent first fixing seats 17, the connecting bolt 18 located on one side of one of the first fixing seats 17 is threadedly connected with a nut 19, and a limiting pin 20 is inserted and installed on the connecting bolt 18 located on one side of the nut 19, and a second fixing seat 21 is fixedly installed on the pad 12, and a connecting block 22 is fixedly installed on the second fixing seat 21 relative to one side of the connecting hoop 13, and a plurality of tooth grooves 23 are provided on the outside of the connecting block 22, and the connecting block 22 is rotatably installed on the connecting bolt 18 located between the two first fixing seats 17, and the pad 12 is rotatably installed on the connecting bolt 18 through the second fixing seat 21 and the connecting block 22, and cooperates with the fixing plate 15 and the tooth block 16 to realize the support of the piston end 10, thereby facilitating the stability of the entire lifting equipment.
