Description

Technical Field

[0001] The utility model belongs to the technical field of building construction engineering technology, and specifically relates to a push-pull type anti-theft movable cover plate for a pump station manhole. Background Art

[0002] With the development of the construction industry, more and more projects use top openings as manholes. Most traditional manholes are vertical channels with small holes, and the cover plates are mostly closed or opened in a flat opening manner. This method is only suitable for manholes with small openings, and the flat opening method is bulky and inconvenient to operate when the cover plate is opened. When this opening method is used for large-sized manholes, a single person may not even be able to operate it. Summary of the invention

[0003] In order to overcome the shortcomings of the background technology, the utility model provides a push-pull anti-theft movable cover for a pump station manhole. The movable cover opens or closes the hole cover by sliding through the bottom steel rails and double-sided rollers, making it convenient to open or close large-sized hole covers.

[0004] To achieve the above purpose, the utility model is implemented through the following technical solutions:

[0005] A push-pull type anti-theft movable cover plate for a pump station manhole, the push-pull type movable cover plate comprising a steel rail (2), an H-shaped double-sided track wheel (3), a cover plate keel (4), and a steel cover plate (5), the cover plate keel (4) being firmly welded to the inner surface of the steel cover plate (5) horizontally and vertically at a certain interval, the H-shaped double-sided track wheel (3) being mounted on the cover plate keel (4), and the steel rail (2) being fixed to both sides of the manhole by pre-buried bolts.

[0006] Furthermore, a row of protective steel plates (1) is installed on the outer side of the steel rail (2).

[0007] Furthermore, a cover plate baffle (8) is provided at the rear of the cover plate keel (4) under the steel cover plate (5) and is fixed to the cover plate.

[0008] Furthermore, a limiting iron block (10) is firmly welded to the tail of the steel rail (2) to prevent the movable cover from detaching from the steel rail (2) when the movable cover is pushed backward.

[0009] Furthermore, a lock buckle (7) is installed at the front of the cover plate keel (4) under the steel cover plate (5).

[0010] Furthermore, lifting ears (6) are welded at both ends of the cover plate keel (4).

[0011] Beneficial effects of the utility model:

[0012] The utility model uses the steel rails and double-sided track wheels at the bottom of the cover plate to move the cover plate by utilizing the sliding principle, so that one person can open or close it, and at the same time, the safety factor is improved, and the shortcomings of the flat opening cover plate, such as being bulky, inconvenient to operate, and having great potential safety hazards, are solved; at the same time, a limit device is installed at the end of the track to prevent the cover plate from derailing when sliding; a protective steel plate is installed on the outside of the track, which also plays a role in protecting the track and the cover plate.

[0021] In order to make the purpose, technical solution and beneficial effects of the present invention clearer, the preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings to facilitate understanding by technicians.

[0022] Example: Figures 1-5As shown in the figure, a push-pull anti-theft movable cover plate for the manhole of a pumping station includes a steel rail 2, an H-shaped double-sided track wheel 3, a cover plate keel 4, and a steel cover plate 5. The cover plate keel 4 is made of a 40×40×2 square steel pipe and is firmly welded horizontally and vertically on the inner surface of the steel cover plate 5 at a pre-calculated spacing. To ensure the normal sliding of the cover plate, the best 4 positions for installing the track wheels are selected according to the size of the cover plate, and 4 H-shaped double-sided track wheels 3 are installed at the positions of the cover plate keel. According to the spacing of the H-shaped double-sided track wheels, the steel rail 2 is fixed on both sides of the manhole by using pre-embedded bolts on both sides of the manhole; the cover plate moves by sliding the double-sided track wheel 3 on the steel rail 2. The steel rail uses a QU70 track steel rail, and the protective steel plate uses a 10-mm-thick steel plate. The utility model can be opened or closed by one person. At the same time, the safety factor is improved, and the disadvantages of the flat-opening cover plate such as being bulky, inconvenient to operate, and having greater potential safety hazards are solved.

[0023] Preferably, a row of protective steel plates 1 is installed on the outside of the steel rail 2 to prevent damage to the steel rail and the sliding cover plate by external uncertain factors. At the same time, to prevent rainwater from seeping into the room through the side seams of the cover plate, a water retaining wall 9 with a size of 200 mm×200 mm is provided around the manhole.

[0024] Preferably, a cover plate baffle 8 is provided at the tail of the cover plate keel 4 under the steel cover plate 5 and is fixed to the cover plate. When the movable cover plate is pulled forward, the baffle 8 and the water retaining wall 9 at the tail of the manhole together play a limiting role to prevent the movable cover plate from detaching from the steel rail 2.

[0025] Preferably, a limiting iron block 10 is firmly welded at the tail of the steel rail 2 to prevent the movable cover plate from detaching from the steel rail 2 when the movable cover plate is pushed backward.

[0026] Preferably, a lock catch 7 is installed at the front of the cover plate keel 4 under the steel cover plate 5. A lock nose matching the lock catch is pre-embedded inside the water retaining wall at the front of the manhole to facilitate the later management personnel to close and manage the manhole.

[0027] Preferably, lifting lugs 6 are welded at both ends of the cover plate keel 4. The cover plate lifting lugs are made of A8 round steel. It is convenient to lift the cover plate when installing and disassembling the cover plate.

[0028] Working process:

[0029] As Figure 1As shown in the figure, when installing the push-pull type anti-theft movable cover plate, first, mark the central axes of the tracks on both sides of the access hole. Then, according to the marked central axes, mark the positions of the fixing bolts on both sides of the central axis at intervals of 300 mm to 500 mm. Then, install the prepared protective steel plate and steel rail in the order shown in the figure, and fix them at the predetermined positions using expansion bolts. Make the movable cover plate according to the figure (including the cover plate, cover plate keel, cover plate baffle, lock, lifting lug, double-sided track wheel, etc.). Then, slowly push and pull the pre-made cover plate from the tail of the steel rail until it is in place. After the cover plate is installed in place, install the limiting device at the tail of the steel rail.

[0030] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in terms of form and details without departing from the scope defined by the claims of the present invention.
