Embodiment Construction

[0027] In order to better understand the above-mentioned technical solution, the above-mentioned technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0028] Such as Figure 1 to Figure 3 As shown, an embodiment of the present invention proposes a complex crane, including a base 10, a lifting pallet 20, a connecting rod support 30 connected between the base 10 and the lifting pallet 20, and a rotating core connected to the lifting pallet 20 The shaft assembly 40, and the rotary drive mechanism 50 connected to the rotary mandrel assembly 40, the rotary drive mechanism 50 is used to twist the lifting pallet 20 by driving the rotation of the rotary mandrel assembly 40, allowing the connecting rod support 30 to adjust the twist angle, To impel the lifting pallet 20 to rise or fall. In this embodiment, the number of connecting rod supports 30 is three, and the three connecting rod supports 30 are c...

Abstract

The invention discloses a complex crane. The complex crane comprises a base, a hoist supporting plate, connecting rod supports connected between the base and the hoist supporting plate, a rotary mandrel assembly connected with the hoist supporting plate, and a rotary driving mechanism connected with the rotary mandrel assembly; and the rotary driving mechanism is used for twisting the hoist supporting plate by driving the rotary mandrel assembly to rotate, so that the connecting rod supports adjust the twisting angle to promote the hoist supporting plate to ascend or descend. According to thecomplex crane, the automation degree is high, and time and labor are saved; the hoisting speed is high, and the safety is high; and the service life of the product is long, and the stability is high.

Description

technical field [0001] The invention relates to the technical field of cranes, and in particular discloses a complex crane. Background technique [0002] Cranes, also known as crown cranes, aerial cranes, and cranes, refer to multi-action hoisting machinery that vertically lifts and horizontally transports heavy objects within a certain range. According to the structural form, cranes are mainly divided into light and small lifting equipment, bridge type (bridge type, gantry crane), jib type (self-propelled, tower type, portal type, railway type, pontoon type, mast type crane) , Cable type. [0003] Light and small lifting equipment generally has only one lifting mechanism, which can only make a single lifting movement for heavy objects. Belong to this category mainly include: Jack. Jack refers to the light and small lifting equipment that uses a rigid jacking part as a working device to lift heavy objects within a small stroke of a top bracket or a bottom claw. Jack is m...
