Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of well lid, especially hydraulic well lid. BACKGROUND

[0002] As an indispensable infrastructure component in water, electricity, gas, heating and municipal fields, the opening operation of the well lid is the primary step of daily operation and maintenance of various industries. Traditionally, this step relies on the manual prying of the well lid with a pry bar, however, the non-portability of the pry bar brings many inconveniences to the staff who need to frequently operate the well lid. When there is a lack of pry bar, the opening of the well lid becomes a big problem, and it is also unrealistic to require each staff to carry a pry bar with them. With the development of technology, hydraulic well lid appears. When using this type of well lid, a hydraulic rod is installed on the well lid. When the staff pulls the well lid, the well lid is pushed by the hydraulic cylinder, so that the well lid is automatically opened.

[0003] However, the existing hydraulic well lid is directly embedded in the concrete for fixation when in use. If the well lid needs to be replaced later, it will take a long time to destroy the concrete before the well lid can be replaced, so the replacement of the well lid is difficult and the efficiency is low. In addition, the existing well lid has a fixed pre-embedding depth when working. When the installation position of the well lid is far away from the original ground layer, the staff needs to pre-embed the well lid by pouring the concrete foundation and wait for it to solidify before installing the well lid, thus prolonging the construction time and reducing the construction efficiency. UTILITY MODEL CONTENTS

[0004] The utility model provides a hydraulic well lid to solve the problem of inconvenient replacement of the existing well lid.

[0005] In order to achieve the above purpose, the utility model provides the following technical scheme: a hydraulic well lid, comprising a shielding piece and a pre-embedded piece, a through cavity is vertically provided on the pre-embedded piece, the shielding piece comprises a mounting frame and a shielding part, the shielding part is rotationally connected to the top of the mounting frame, and the shielding part is installed inside the cavity, a plurality of clamping grooves are provided on the mounting frame, a plurality of connecting rods are fixedly connected to the inner wall of the cavity, the connecting rods are matched with the clamping grooves one by one, and a screw ring for abutting against the mounting frame is rotationally connected to the connecting rod.

[0006] Preferably, the pre-embedded piece comprises a pre-embedded frame, the cavity is provided on the pre-embedded frame, and a plurality of supporting rods are rotationally connected to the pre-embedded frame.

[0007] Preferably, the supporting rod comprises a connecting pipe, a connecting groove is formed by the top of the connecting pipe, and a connecting head matched with the connecting groove is fixedly connected to the bottom of the connecting pipe.

[0008] Preferably, the shielding part comprises a top plate, and a reinforcing plate is fixedly connected to one side of the top plate close to the mounting frame.

[0009] Preferably, a hydraulic rod is rotatably connected between the reinforcing plate and the mounting frame.

[0010] Preferably, a plurality of reinforcing ribs are fixedly connected to the inside of the reinforcing plate.

[0011] In the above technical solution, the technical effects and advantages of the utility model are provided.

[0012] (1) After the pre-embedded part is pre-embedded, the clamping groove on the mounting frame is clamped with the connecting rod on the cavity, and the screw ring is screwed with the connecting rod, so as to resist the mounting frame to the pre-embedded part. When the personnel need to replace the well cover, only need to unscrew the screw ring, and the well cover can be disassembled and replaced, without wasting a long time to destroy the concrete to replace the well cover, reducing the difficulty of replacing the well cover, improving the replacement efficiency of the well cover.

[0013] (2) By setting a plurality of connecting pipes, the connecting pipe is screwed with the connecting groove on the other connecting pipe through the connecting head, so that the number of connecting pipes required by the personnel is connected in sequence, and then the length of the connecting pipe is adjusted, and the connecting pipe with the adjusted length is screwed with the pre-embedded frame. The depth of the well cover can be adjusted according to the required depth, so that the personnel do not need to pre-cast the foundation by concrete and wait for solidification, which shortens the construction time and improves the construction efficiency.
