Clamping device for spare tire of transport vehicle

Abstract

The invention relates to a spare tire clamping device of a carrier vehicle. The spare tire clamping device is characterized by comprising a pressure plate, a pressure rod and a support mechanism, wherein the support mechanism comprises a baseplate, a vertical pipe and three support rib plates; the vertical pipe is vertically fixed in the center of the baseplate, and is provided with an internal thread; the two ends of the support rib plates are respectively fixed on the baseplate and the vertical plate; the support rib plates are arc structures; support lug plates are arranged on the support rib plates; chutes are formed in the lug plates; mounting screw holes are formed in the baseplate; the pressure plate comprises a groove-shaped plate body; a through hole is formed in the center of the plate body; table shoulders are arranged at the two ends of the plate body; the pressure rod comprises a vertical rod and a handle connected in a T form; a limiting plate and a thread are arranged on the vertical rod; the pressure plate coats the vertical rod; and the vertical rod is in threaded connection with the vertical pipe. The spare tire clamping device has the beneficial effects of adaptation to tires with different specifications, consideration of clamping and lifting of the tires and convenience and simplicity in operation.

Description

technical field [0001] The invention relates to the field of tools for oilfield transport vehicles, in particular to a clamping device for a spare tire of a transport vehicle. Background technique [0002] Oilfield equipment is mainly sent to the destination by various types of transport vehicles. During the transportation process, due to road conditions and other reasons, the transport vehicles often have to attach spare tires. However, the current spare tire clamping device often leads to difficulty in clamping the bracket due to the unequal air pressure between the rim of the spare tire and the spare tire, and has poor versatility. There is a disadvantage that one kind of bracket can only be used on one kind of spare tire. During the process, operations such as fastening, dismounting and hoisting of the rim are relatively complicated. Contents of the invention [0003] The present invention aims at the deficiencies in the above-mentioned prior art, and provides a spare...
