Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary opening of fire manhole covers, in particular to an opening tool for fire manhole covers. Background Art

[0002] Fire wells refer to various types of inspection wells set up for the convenience of maintenance and installation of urban underground infrastructure such as power supply, water supply and drainage, communications, gas pipes, and street light lines. Fire wells need to be covered with manhole covers. There are many fire well covers on container terminals. For safety reasons, they need to be opened frequently to maintain fire-fighting facilities. Fire well covers are generally heavy and installed tightly. It is difficult to open them by hand and tools are required to open them. In the past, terminal personnel needed to use unreasonable tools to open fire well covers, which was time-consuming and labor-intensive, and often resulted in hidden dangers that the fire well covers could not be opened.

[0003] The patent application with the authorization announcement number CN219603214U discloses an emergency opening tool for a fire manhole cover, including a wire rope, a hook and a handle, a protective tube is provided on the outside of the hook, a storage slot is provided inside the protective tube, the hook is placed inside the storage slot, the bottom end of the wire rope extends into the storage slot and is fixed to the hook, the bottom of the protective tube is rotatably connected with a sealing cover, a closing component is provided between the sealing cover and the bottom end of the protective tube, the closing component includes a built-in slot, a movable rod and a slot, and one end of the movable rod is stuck in the slot. When using a hook and a handle, there is sometimes a risk of slipping due to force, and the length cannot be adjusted. For a manhole cover in a deep pit, the worker needs to bend over or jump into the deep pit to open the fire manhole cover, which is a great disadvantage. Utility Model Content

[0004] In order to overcome the defects of the prior art such as sliding down under force and being unable to adjust the length, the utility model provides an opening tool for a fire manhole cover.

[0005] The utility model solves the technical problem by adopting the following technical solution: an opening tool for a fire manhole cover, comprising a pry bar, one end of which is provided with an arc-shaped hook head which can be inserted into a hole groove of the fire manhole cover, the other end of which is provided with a handle, the inner wall of the arc-shaped hook head is provided with an anti-slip strip, and the pry bar is a retractable adjustment rod.

[0006] As a further improvement of the utility model, the arc-shaped hook head is a semicircular hook head.

[0007] As a further improvement of the utility model, one end of the arc-shaped hook head is welded to the pry bar, and the other end of the arc-shaped hook head is provided with a tip.

[0008] As a further improvement of the utility model, a rib plate connected to the arc-shaped hook head is provided on the pry bar.

[0009] As a further improvement of the present invention, the handle is a triangular handle.

[0010] As a further improvement of the utility model, an anti-slip cover is provided on the handle.

[0011] Compared with the prior art, the utility model has the beneficial effects: in this solution, the pry bar is a retractable adjusting rod. According to the height of the foundation pit, the length of the pry bar is adjusted, and the staff can operate it by standing on the foundation pit. The arc-shaped hook head hooks the opening hole of the fire manhole cover, and the inner wall of the arc-shaped hook head is provided with an anti-slip strip to reduce the risk of slipping under force. The staff can quickly open or close the fire manhole cover by applying force with the handle, which saves time and effort and greatly saves the time of opening and closing the fire manhole cover.
