Description

TECHNICAL FIELD

[0001] The utility model relates to a well lid auxiliary tool technical field, concretely relates to an adjustable well lid prying auxiliary device. BACKGROUND

[0002] There are many underground pipelines in city construction, such as sewer, underground gas pipeline, water supply pipeline, power pipeline, communication pipeline, national defense pipeline and the like, and these pipelines have an outlet to the ground every interval, and the section from the pipeline to the ground is called a inspection well, and the inspection well mouth is usually flush with the ground, so a cover is needed to cover the inspection well, which is called an inspection well cover. The inspection well cover is usually made of reinforced concrete, metal, reinforced plastic and the like, and the shape is mainly round and square.

[0003] At present, when cleaning the underground pipeline, the well cover needs to be opened to allow people or equipment to enter, and the traditional well cover opening tool usually adopts a pry bar with a hook, which hooks the cross hole on the well cover, and then the well cover is pried open. However, the hook hole is prone to slipping, which affects the prying of the staff, and the hook and the pry bar are usually designed as one piece, which is fixed in position on the pry bar, and there are many inconveniences in use. CONTENT OF THE UTILITY MODEL

[0004] The utility model solves the above problems and provides an adjustable well lid prying auxiliary device.

[0005] The utility model is realized through the following technical scheme: an adjustable well lid prying auxiliary device, comprising a pry bar, and a cover opening device is arranged on the pry bar, characterized in that the cover opening device comprises an upper semicircular clamp and a lower semicircular clamp, both sides of the upper and lower semicircular clamps are provided with fixing holes, fixing bolts are arranged in the fixing holes, a hinge piece is arranged at the bottom of the lower semicircular clamp, a screw rod is arranged below the hinge piece, the screw rod is externally threaded connected with a sleeve, the bottom of the sleeve is provided with a connecting rod, and the bottom of the connecting rod is provided with a cross-shaped hook.

[0006] Further, the upper semicircular clamp and the lower semicircular clamp clamp the pry bar through the fixing bolts passing through the fixing holes.

[0007] Further, the size of the cross-shaped hook is adapted to the size of the cross hole of the well cover, the transverse length of the cross-shaped hook is greater than the longitudinal length, and is also greater than the longitudinal length of the cross hole.

[0008] Further, the hand-held end of the pry bar is provided with an anti-skid rubber sleeve, and the non-hand-held end is treated as a flat surface.

[0009] The utility model has the advantages that the upper and lower semicircular clamps are movably clamped on the pry bar, the position of the cover opening device on the pry bar is moved, and the staff can conveniently adjust the position of the cover opening device on the pry bar according to the requirements.

[0010] This invention utilizes a cross-shaped hook to enter the cross hole of a manhole cover, and then rotates the sleeve to make the cross hook rotate and hook the manhole cover, preventing the cross hook from slipping out of the cross hole, thus increasing stability and facilitating subsequent prying operations by workers.

Detailed Implementation

[0016] To make the purpose, technical solution and beneficial effects of this utility model clearer, the technical solution of this utility model will be further explained below with reference to the embodiments.

[0017] like Figures 1 to 4 As shown, an adjustable manhole cover prying auxiliary device includes a pry bar 1, on which a cover opening device 2 is provided. The cover opening device 2 includes an upper semi-circular clamp 201 and a lower semi-circular clamp 202. Fixing holes 203 are provided on both sides of the upper and lower semi-circular clamps 202. Fixing bolts 204 are installed in the fixing holes 203. The upper semi-circular clamp 201 and the lower semi-circular clamp 202 clamp the pry bar 1 by passing the fixing bolts 204 through the fixing holes 203. The lower semi-circular clamp 202 has a hinge piece 205 at its bottom, and a screw 206 is located below the hinge piece 205. The screw 206 is threadedly connected to a sleeve 207, that is, the sleeve 207 has an internal thread, and the screw 206 has an external thread. The bottom of the sleeve 207 has a connecting rod 208, and the bottom of the connecting rod 208 has a cross-shaped hook 209. The size of the cross-shaped hook 209 is adapted to the size of the cross hole of the manhole cover, so that the cross-shaped hook 209 can easily enter the cross hole. The lateral length of the cross-shaped hook 209 is greater than its longitudinal length and also greater than the longitudinal length of the cross hole, so that the cross-shaped hook 209 can hook the manhole cover by rotating its angle after entering the cross hole.

[0018] The handheld end of the pry bar 1 is equipped with a non-slip rubber sleeve, while the non-handheld end is flattened.

[0019] In use, install the opening device 2 on the pry bar 1, that is, determine the position where the opening device 2 needs to be installed on the pry bar 1, and then tighten the fixing bolts 204 on both sides of the upper and lower semi-circular clamps 202, so that the upper semi-circular clamp 201 firmly clamps the pry bar 1, thereby preventing it from sliding on the pry bar 1. After fixing the opening device 2, insert the cross-shaped hook 209 into the cross hole of the manhole cover, and then rotate the sleeve 207 about 90 degrees. The sleeve 207 drives the cross-shaped hook 209 to rotate, so that the lateral length of the cross-shaped hook 209 corresponds to the longitudinal hole of the cross hole. Since the lateral length of the cross-shaped hook 209 is greater than the longitudinal length of the cross hole, the cross-shaped hook 209 is stuck in the cross hole of the manhole cover. At this time, lift the pry bar 1, and the pry bar 1 pulls the cross-shaped hook 209 upward to pry open the manhole cover.

[0020] Except for the technical features described in the specification, all other technical features are known to those skilled in the art.
