Problems solved by technology

This method is time-consuming and labor-intensive, and requires the opening personnel to have strong upper body strength, and some square manhole covers cannot be opened; in addition, the loss of each opening is also large, because the crowbar will damage the composite material and the thin-walled manhole. Damage caused by prying hole of manhole cover

Abstract

The invention provides a portable inspection well lid opening device, which comprises a pedal part comprising a pedal, a pedal support rod and a pedal connecting rod which are connected in sequence; the pinch bar part comprises a pinch bar, a fixing platform arranged at the two ends of the pinch bar and a pinch bar connecting rod, a first fixing shaft is arranged in the fixing platform in a penetrating mode, and the lower end of the first fixing shaft is provided with a first fixing rod used for being inserted into a cover prying hole of an inspection well cover; a hollow pinch bar shaft sleeve is arranged at each of the two ends of the pinch bar connecting rod; a pinch bar clamping seat is arranged on the outer side of each pinch bar shaft sleeve; the supporting leg part comprises a supporting leg connecting rod, a main supporting leg rotationally connected with the supporting leg connecting rod and branch supporting legs arranged at the two ends of the supporting leg connecting rod; the invention further provides a using method of the portable inspection well lid opening device. The inspection well lid has the advantages that the lever principle is adopted, the inspection well lid is pried by means of the weight of a human body, and people with weak upper limb strength can use the inspection well lid conveniently; the foldable design is adopted, and carrying by a single person is facilitated.

Description

technical field [0001] The invention relates to the technical field of inspection well operation and maintenance, in particular to a portable inspection well cover opening device and a use method thereof. Background technique [0002] In the daily maintenance and operation status monitoring of the municipal pipeline network, it is necessary to frequently open the manhole cover of the inspection well. The design and installation methods of the existing inspection well covers are mainly based on safety, anti-theft, and durability, and lack the consideration of easy opening. Therefore, construction crowbars are often used to open the inspection well covers at present. This method is time-consuming and labor-intensive, and requires the opening personnel to have strong upper body strength, and some square manhole covers cannot be opened; in addition, the loss of each opening is also large, because the crowbar will damage the composite material and the thin-walled manhole. The pr...
