Description

Technical Field

[0001] The utility model belongs to the technical field of inspection wells, and in particular relates to an inspection well anti-falling device and an inspection well. Background Art

[0002] Inspection wells are an important part of the city's underground pipeline system, and are mainly used for the maintenance and inspection of municipal facilities such as cables, communications, and drainage. Since inspection wells are usually deep and have small openings, there is a risk of workers or pedestrians accidentally falling in, so setting up a fall prevention device is a necessary measure to ensure operational safety and prevent accidents. Existing fall prevention devices are often designed to adapt to inspection wells of specific sizes and types, lacking sufficient versatility and adaptability. Utility Model Content

[0003] The purpose of the utility model is to provide an inspection well anti-falling device and an inspection well in view of the above-mentioned technical problems. The anti-falling device can be applicable to inspection wells of different specifications.

[0004] In view of this, the utility model provides an anti-fall device for an inspection well, comprising a first cover body and a second cover body, an extension component is arranged between the first cover body and the second cover body, the extension component can adjust the distance between the first cover body and the second cover body, the first cover body and the second cover body are mounted in a fixing groove, the fixing groove is arranged on the inner wall of the well body, a locking component is arranged in the first cover body and the second cover body, and a limiting groove is arranged in the fixing groove corresponding to the locking component.

[0005] In the present technical scheme, the first cover body and the second cover body are movably connected by setting an extension component. During installation, the first cover body is placed on the fixed groove in the well body, and the second cover body is pulled to move to the side away from the first cover body until the side wall of the second cover body and the inner wall of the fixed groove are abutted against each other. The positioning component set in the first cover body and the second cover body is inserted into the limiting groove to limit the first cover body and the second cover body to prevent movement between the cover bodies. The anti-fall device for the inspection well can be applied to inspection wells of different specifications. At the same time, the setting of the positioning component and the limiting groove can also prevent the cover body from moving, thereby ensuring the stability of the anti-fall device for the inspection well and providing sufficient support for people or objects that fall accidentally.

[0006] In the above technical solution, further, the extension component includes a first support tube, the first support tube array is arranged on the inner wall of the first cover body, the second support tube is slidably connected in the first support tube, and the second support tube is arranged on the inner wall of the second cover body corresponding to the first support tube array.

[0007] In this technical solution, the two side covers are connected by an extension component, which is not only suitable for inspection wells of different specifications, but also can reduce the volume and facilitate transportation.

[0008] In the above technical solution, further, the first cover body and the second cover body are both arc-shaped plates that can fit the inner wall of the fixing groove, and both side ends of the first cover body and both side ends of the second cover body are provided with limiting components.

[0009] In the above technical solution, further, the limit assembly includes a first slide groove, the first slide groove is vertically arranged at the end of the cover body, a limit block is slidably arranged in the first slide groove, the limit block and the bottom wall of the first slide groove are connected by a first spring, the first slide groove is connected to the second slide groove, a connecting block is slidably connected in the second slide groove, one side of the connecting block is connected to the limit block, and the other side is connected to the shift block.

[0010] In the above technical solution, further, a locking hole is provided through the shift block, a fixing plate is provided on one side of the shift block, and a connecting hole is provided on the fixing plate, wherein when the limit block is retracted into the first slide groove, the fixing pin can pass through the locking hole and the connecting hole in sequence to limit the limit block.

[0011] In the present technical solution, the protruding setting of the limit block in the limit assembly makes it difficult to stack and transport the anti-fall device. After the limit block is driven by the shift block to compress the first spring and completely retract into the first slide groove, it is fixed by other fixing columns such as a fixing pin through the locking hole on the shift block and the connecting hole on the fixing plate. When installing the anti-fall device, you only need to take out the fixing pin, and the first spring will reset to drive the limit block to extend out of the first slide groove and enter the limit groove for fixation.

[0012] In the above technical solution, further, the outer walls of the first cover body and the second cover body are both provided with positioning structures, and the inner wall of the fixing groove is provided with positioning holes corresponding to the above positioning structures.

[0013] In the above technical solution, further, the positioning structure is a fixing column arrayed on the outer wall of the first cover body and the second cover body, and the fixing column and the inner wall of the positioning hole can abut against each other.

[0014] In the present technical solution, the setting of the fixing column and the positioning hole, when installing the anti-fall device, first match the fixing column on one side cover plate with the positioning hole on the inner wall of the fixing groove, and then pull the other side cover plate away from the cover plate of this side until the fixing column set on the side cover plate and the positioning hole on the same side are matched, and then fully fixed by connecting the limit assembly and the limit groove, which can limit the movement of the anti-fall device in the vertical direction, ensure the full fixation of the anti-fall device and the well body, and ensure that it can normally perform the anti-fall function.

[0015] In the above technical solution, further, an inspection well including the above inspection well anti-fall device is provided.

[0016] The beneficial effects of the utility model are:

[0017] 1. This inspection well anti-fall device can be applied to inspection wells of different specifications. At the same time, the setting of the positioning assembly and the limit groove can also prevent the cover from moving, ensure the stability of the inspection well anti-fall device, and provide sufficient support for people or objects that accidentally fall in;

[0018] 2. The protruding setting of the limit block in the limit assembly makes it difficult to stack and transport the anti-fall device. After the limit block is driven by the shift block to compress the first spring and completely retract into the first slide groove, other fixing columns such as a fixing pin are passed through the locking hole on the shift block and the connecting hole on the fixing plate for fixing. When installing the anti-fall device, only the fixing pin needs to be removed, and the first spring is reset to drive the limit block to extend out of the first slide groove and enter the limit groove for fixing;

[0019] 3. The setting of fixing columns and positioning holes. When installing the anti-fall device, first match the fixing columns on one side cover with the positioning holes on the inner wall of the fixing groove, and then pull the other side cover away from the cover until the fixing columns set on the side cover match the positioning holes on the same side, and then fully fix them through the connection of the limit assembly and the limit groove. This can limit the movement of the anti-fall device in the vertical direction, ensure the full fixation of the anti-fall device and the well body, and ensure that it can normally perform the anti-fall function.
