Device for clamping vehicle-mounted large-diameter cylinder

Abstract

The invention discloses a device for clamping a vehicle-mounted large-diameter cylinder. The device mainly comprises a crossed arm (1), a clamping seat (2), a transportation fixing cylinder (3), a transportation fixator (4), an adjusting screw and nut (5), a butterfly plate and spring combination (6), a clamping base trunnion (7), a buffer device (8), a screw rod (9), a bearing (10), a pinion (11), a gear wheel (12) and a cycloidal hydraulic motor (13). By the device, the conventional cylinder clamping mechanism and the conventional transportation fixing device of a special vehicle are combined into a set of system, so that the special vehicle can load and transport pressure vessels or large-diameter cylindrical equipment conveniently and rapidly and can reliably transport the load pressure vessels or large-diameter cylindrical equipment.

Description

technical field [0001] The invention belongs to the technical field of special vehicle design, and particularly relates to a vehicle-mounted large-diameter cylinder clamping device, which is used to restrain the pressure vessel or large-diameter cylinder equipment from bouncing up and down when the special equipment transport vehicle is in the transportation state. Before the large-diameter cylindrical equipment is erected, hoisted and hooked to other special vehicles, the clamping arm and transport fixing device can be automatically opened without affecting the erection, hoisting and hooking actions of the pressure vessel or large-diameter cylindrical equipment. Background technique [0002] When the special vehicles carrying pressure vessels or large-diameter cylindrical equipment are in the transportation state, they must simultaneously restrain the pressure vessels or large-diameter cylindrical equipment from beating in four directions: up, down, left, and right. Two sets...

Problems solved by technology

[0002] When the special vehicles carrying pressure vessels or large-diameter cylindrical equipment are in the transportation state, they must simultaneously restrain the pressure vessels or large-diameter cylindrical equipment from beating in four directions: up, down, left, and right. Two sets of mechanisms are used in the original special transport vehicles respectively. Realize the above functions, that is, the clamping mechanism and the transport fixing device. The clamping mechanism is driven by an oil cylinder to move the crank slider mechanism, and then drives the crank rocker mechanism to realize the opening and tightening of the mechanism. This structure mainly has the following disadvantages: First, there is a dead point in the crank slider mechanism, and the failure rate is high; second, the mechanism does not have the ability to adapt to the deformation of the chassis beam of special vehicles; The loading time is shortened; Fourth, because the original structure is driven by the hydraulic locking mechanism, the self-locking function is not good
