Description

Novel inspection shaft anti-falling device

Technical Field

The utility model relates to the technical field of inspection wells, in particular to a novel inspection well anti-falling device.

Background

With the promotion of town construction, the requirements for reasonable laying of urban water supply and drainage and other fluid conveying pipe networks are higher and higher. Plastic inspection wells have become an indispensable unit for town water supply and drainage pipe network construction. The inspection shaft is a vertical shaft which is built at regular intervals on the position of the underground pipeline. The device is mainly used for overhauling pipelines, removing sludge and connecting pipelines in different directions and at different heights. In particular to a flushing manhole, a street manhole, a water diversion manhole, a sewage manhole and the like. The plastic inspection well consists of a well seat, a well shaft, a well cover or a protective cover seat and inspection well accessories, and a pressure-bearing ring is required to be configured according to the standard number CJ/T326-2010.

In order to improve the safety of a plastic inspection well, an anti-falling plate is generally arranged below the well cover, so that personnel can be prevented from carelessly falling into the inspection well to cause injury. The traditional anti-falling plate is installed in a hanging mode, and is easy to shake in the use process, and if an emergency occurs, secondary injury to a human body is easy to occur; and the water is easy to float upwards and be flushed out during water rising, so that danger is caused.

Therefore, how to avoid the above situation becomes a problem to be solved by those skilled in the art.

Disclosure of Invention

In order to solve the technical problems in the background technology, the utility model discloses a novel inspection well anti-falling device.

The utility model provides a novel inspection shaft anti-falling device, which comprises an anti-falling plate and a clamping plate;

the clamping plate is fixedly arranged on the pressure-bearing ring;

the anti-falling plate is arranged on the clamping plate in a male-female clamping manner.

The setting of joint board not only realizes preventing weighing down board quick assembly disassembly, keeps stable moreover after preventing weighing down the board installation, not only can not appear rocking, also can not be washed out because of rising water come-up to avoid taking place danger, cause personnel's injury.

Because traditional anti-falling plate and the public female joint of joint board are fixed through static friction after, break away from easily when ground vibrations or water submergence, so further improve and solve this problem, specifically, anti-falling plate is equipped with a plurality of rotational symmetry's bayonet socket, and the joint board is equipped with the latch of joint bayonet socket.

The specific structure of the bayonet and the latch is as follows: the outer ring of the anti-falling plate is provided with a plurality of rotationally symmetrical clamping blocks which are outwards protruded, and the bayonet is arranged on the clamping blocks;

the clamping plate is L-shaped and comprises a transverse plate and a longitudinal plate, the longitudinal plate is fixedly connected with the bearing ring, and the clamping teeth are arranged on the transverse plate.

The tooth part of the latch forms a tapered wedge shape, and comprises two toothed plates which are symmetrically arranged, a stop block is arranged between the toothed plates, and a distance is arranged between the toothed plates and the stop block. The dog is used for the pinion rack crooked spacing, avoids the fracture.

Drawings

The utility model will be further described with reference to the drawings and examples.

FIG. 1 is a schematic diagram of the structure of the present utility model;

FIG. 2 is an exploded view of the present utility model;

FIG. 3 is a cross-sectional view of a bayonet catch;

in the figure: 1. an anti-falling plate; 2. a clamping plate; 3. a bayonet; 4. latch teeth; 5. a clamping block; 21. a transverse plate; 22. a longitudinal plate; 41. a toothed plate; 42. and a stop block.

Detailed Description

The utility model will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic representations which merely illustrate the basic structure of the utility model and therefore show only the structures which are relevant to the utility model.

Embodiment one:

as shown in fig. 1 and 2, the utility model relates to a novel inspection well anti-falling device, which comprises a circular anti-falling plate 1 with a mesh plate shape and a clamping plate 2 clamped with the circular anti-falling plate 1, wherein the specific clamping structure is as follows:

the outer ring of the anti-falling plate 1 is provided with a plurality of clamping blocks 5 which are rotationally symmetrical and are protruded outwards, and the clamping blocks 5 are provided with bayonets 3.

The clamping plate 2 is L-shaped and comprises a transverse plate 21 and a longitudinal plate 22, the longitudinal plate 22 is fixedly connected with the pressure-bearing ring through a plurality of bolts, the transverse plate 21 is horizontally arranged, and the upper end of the transverse plate is provided with a clamping tooth 4. As shown in fig. 3, the tooth portion outer side of the latch 4 is provided with an inclined plane, and forms a tapered wedge shape, and the latch comprises two toothed plates 41 which are symmetrically arranged, wherein a stop block 42 is arranged between the toothed plates 41, and a space is arranged between the toothed plates and the stop block 42. The stop block 42 is used for limiting the bending of the toothed plate 41 to avoid breakage. When the bayonet 3 is clamped with the latch 4, the toothed plate 41 automatically bends inwards under the guiding action of the inclined plane; when the tooth part is separated from the bayonet 3, the toothed plate 41 is reset, and the tooth part is clamped with the end part of the bayonet 3, so that the anti-falling plate 1 is fixed.

The setting of joint board 2 not only realizes preventing weighing down board 1 quick assembly disassembly, keeps stable moreover after preventing weighing down board 1 installs, not only can not appear rocking, also can not be by the punching out of rising because of rising to avoid taking place danger, cause personnel's injury.

With the above-described preferred embodiments according to the present utility model as an illustration, the above-described descriptions can be used by persons skilled in the relevant art to make various changes and modifications without departing from the scope of the technical idea of the present utility model. The technical scope of the present utility model is not limited to the description, but must be determined according to the scope of claims.
