Description

Technical Field

[0001] The utility model belongs to the field of tools and tools, and in particular relates to a manhole cover opening device. Background Art

[0002] Usually, manhole covers are opened manually, but because manholes are generally relatively humid, in winter, water vapor condenses and causes the manhole cover and the ground to freeze, making it difficult to open manually. Utility Model Content

[0003] The technical problem to be solved by the utility model is that the manhole cover is frozen to the ground and is difficult to be opened by hand.

[0004] In order to solve the above technical problems, the specific technical solutions of the utility model are as follows:

[0005] A manhole cover opening device comprises a foot pedal 1, a pull rod 2, a handrail 3, an iron chain 4, a slotted pin 5 and a universal wheel 6; the foot pedal 1 is an iron plate, the pull rod 2 is vertically fixed to the right side of the top of the foot pedal 1, and the top of the pull rod 2 is provided with a handrail 3; one end of the iron chain 4 is fixed to the side of the pull rod 2, and the other end is fixedly provided with a slotted pin 5; the length of the iron chain is less than the distance between its fixing point and the foot pedal; a universal wheel 6 is provided on the right side of the bottom of the foot pedal 1.

[0006] Among them, the foot pedal size is 10*20 cm.

[0007] Among them, the length of the pull rod is 1 meter.

[0008] Among them, the length of the flat pin is 15 cm.

[0009] The utility model has the following advantages: the device can be freely moved to the top of the ground well to be used as needed, which is convenient for opening the valve well cover, is easy to use, can improve work efficiency and avoid danger when using other tools to open it, and solves the problem of difficulty in opening the ground well cover. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a structural schematic diagram of the manhole cover opening device of the utility model. DETAILED DESCRIPTION

[0011] In order to better understand the purpose, structure and function of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings.

[0012] like Figure 1As shown, the utility model of the manhole cover opening device is based on the principle of lever, an iron pipe is connected to the 10*20 cm iron plate, the lower end of the steel pipe is welded, a handrail is welded above the steel pipe, an iron chain is welded in the middle and upper part of the iron pipe, a straight pin is welded at the other end of the iron chain, and two universal wheels are installed at the front end of the bottom of the iron plate. The device can be freely moved to the top of the manhole to be used as needed, which is convenient for opening the valve manhole cover. It is easy to use, can improve work efficiency and avoid danger when using other tools to open it, and solves the problem of difficulty in opening the manhole cover. It is more convenient and safer than traditional devices.

[0013] In this embodiment, the size of the foot pedal is 10*20 cm, the length of the handrail is 1 meter, the length of the handrail is 40 cm, an iron chain is welded to the upper middle part of the handrail, and the length is 50 cm. A straight pin is welded to the other end of the iron chain, and the length of the straight pin is 15 cm. Two universal wheels are installed at the bottom of one end of the foot pedal handrail.

[0014] When in use, tilt the device forward at an angle of 60 degrees, insert the flat pin into the circular hole of the manhole cover, and when the iron chain is tightened, the flat pin will be horizontal inside the manhole cover. Pull the handrails inward with both hands and press the foot pedal with your foot to easily open the manhole cover.

[0015] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make several modifications and improvements without departing from the principle of the present invention, and these modifications and improvements should also be considered to belong to the protection scope of the present invention.
