Abstract

The invention relates to the technical field of weighing equipment and discloses shallow foundation pit in-head type full vehicle weighing equipment. The equipment comprises two bearing beams which are symmetrically and fixedly mounted on the ground, wherein a matched bearing body is arranged between the two bearing beams; a foundation pit is formed between the lower surface of the bearing body and the ground; two symmetrical L-shaped plates are fixedly connected with the upper surface of the bearing body; lower surfaces of the L-shaped plates are fixedly connected with moving plates through connecting plates; sliding columns are fixedly connected with the lower surfaces of the moving plates; matched chutes are formed in the positions, corresponding to the sliding columns, of the upper surfaces of the bearing beams; the sliding columns are inserted into the chutes, are fixedly connected with first springs and are in sliding connection with the chutes; weighing devices are fixedly connected with one ends, away from the sliding columns, of first springs, and are fixedly mounted at the bottoms of the chutes. According to the equipment, force signal collection units are prevented frombeing affected by rainwater in the foundation pit and other environmental factors, so that the service life of each force signal collection unit is effectively prolonged, and the weighing precision ofthe force signal collection units is effectively improved.

Description

technical field [0001] The invention relates to the technical field of weighing equipment, in particular to an upper-mounted weighing equipment for a shallow foundation pit. Background technique [0002] Large-scale weighing equipment is generally divided into two types: with foundation pit and without foundation pit, and with foundation pit is divided into deep foundation pit and shallow foundation pit; currently, the weighing equipment used for expressway toll lanes generally adopts the shallow foundation pit method. The signal force transmission unit of shallow foundation pit weighing equipment is used to be placed under the carrier. Because the bottom of the foundation pit is wet, it is easy to be flooded and soaked, and the working environment is very harsh. Especially in summer, the force signal acquisition unit is in a state of high temperature and high humidity. , which seriously affects the service life and weighing accuracy of the force signal acquisition unit, and...
