Background technology

As everyone knows, cleaning for the city, adopt suction-type sewer scavenger that inspection shaft is carried out the soil pick-up scale removal, existing suction-type sewer scavenger is when operation, and suction-type sewer scavenger bonnet handwheel commonly used is locked, insufficient strength, the opening and closing time of locking handwheel is very short, and motion space is very little, when being in malleation or negative pressure state as if tank interior, bonnet might rapidly be opened or open very difficult, exists potential danger.

Summary of the invention

The purpose of this utility model is: the auxiliary device that provides a kind of suction-type sewer scavenger tank body bonnet to open and close, when suction-type sewer scavenger carries out blowdown work, slightly open this auxiliary device, tank body malleation or negative pressure are unloaded, open auxiliary device, the handwheel catch gear of suction-type sewer scavenger tank body bonnet again, realize safe discharging, when the suction-type sewer scavenger bonnet need be closed, utilize the difference of the two-way cylinder oil-feed direction of this auxiliary device to control the tank body bonnet is reliably closed.

The technical solution that the utility model is taked is: this auxiliary device comprises the oil cylinder permanent seat, two-way cylinder, the clamp permanent seat, a pipe link, No. two pipe links, clamp and bolt, two pipe links place the inboard of two clamp permanent seats respectively, No. one pipe link passes through bearing pin, pad, jump ring connects the clamp permanent seat, No. two pipe links place the outside of a pipe link respectively, No. two pipe link passes through bearing pin, pad, jump ring connects a pipe link, the clamp upper end places the inboard of No. two pipe links, the clamp lower end places the inboard of clamp permanent seat, on the clamp, the lower end is passed through bearing pin respectively, pad, No. two pipe links of jump ring connection and clamp permanent seat, the tail end hold-down bolt of clamp, the piston end of two-way cylinder is connected on pipe link, and the tailstock end of two-way cylinder is connected between two oil cylinder permanent seats.

Wherein, setting nut is installed on bolt.

During installation, two oil cylinder permanent seats, two clamp permanent seats are welded on the same plane of tank body and are parallel with the line of centers of two-way cylinder, are welded to connect plate on the tank body bonnet, the connecting panel barrel bolt; When hydraulic oil from two-way cylinder wherein during an oil inlet oil-feed, promote piston rod and move right and drive a pipe link and move right and drive No. two pipe links and move right, No. two pipe links drive clamp and move right, and rotate and withdraw from bolt, clamp is opened; When hydraulic oil during from another oil inlet oil-feed of two-way cylinder, it is moving left to promote piston rod, drive a pipe link to left movement, No. one pipe link drives No. two pipe links to left movement, No. two pipe link drives clamp to left movement, compress connecting panel by bolt, the tongue that connecting panel promotes the tank body bonnet embeds the tank body seal ring, and the tank body bonnet is closed and locked.

The utility model is simple in structure, and is with low cost, easy to operate, fluid control, and safety is good, and high efficiency can also be applied on the reliable tank body that opens and closes of similar needs.
