Specific embodiments

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model.

[0022] Embodiment 1:

[0023] The main method of this embodiment is an underground valve well manhole cover opening device, as shown in Figure 1 and Figure 2As shown in the figure, it includes a support framework and a prying component. The support framework includes a positioning member 1 and an abutting member 2. The positioning member 1 is welded to the abutting member 2. The abutting member 2 is arranged on one side of the positioning member 1. The prying component is connected to the middle of the positioning member 1. The prying component and the abutting member 2 are arranged on the same side of the positioning member 1. Well cover connection components 5 are respectively arranged on the left and right sides of the abutting member 2. The well cover connection components 5 are used to connect the well cover. The prying component abuts against the abutting member 2 to pry up the well cover. When the prying component presses down to pry the well cover, its middle abuts against the abutting member 2, and the abutting member 2 forms a support point between the well cover and the prying component. An abutting portion 21 is arranged in the middle of the abutting member 2. The abutting portion 21 is located in the middle of the abutting member 2 and is recessed. The prying component abuts against the abutting portion 21. The prying component includes a connecting rod 3 and a steel rod 4. The connecting rod 3 is threadedly connected to the positioning member 1. The connecting rod 3 and the positioning member 1 are set as a detachable structure, which is convenient for handling. The middle of the connecting rod 3 abuts against the abutting portion 21. The connecting rod 3 is a tubular hollow structure, and an opening is arranged on one side of it. The diameter of the steel rod 4 is matched with the inner diameter of the connecting rod 3. A connecting portion 31 is arranged at the opening end of the connecting rod 3. A transverse through hole and a longitudinal through hole are arranged on the connecting portion 31. The transverse through hole is communicated with the longitudinal through hole, and the longitudinal through hole is communicated with the connecting rod 3. The steel rod 4 is matched with the transverse through hole and the longitudinal through hole. The steel rod 4 is arranged at the end of the connecting rod 3. The steel rod 4 can be longitudinally inserted into the connecting rod 3 through the longitudinal through hole of the connecting portion 31, or can be horizontally passed through the transverse through hole of the connecting portion 31 and then be perpendicular to the connecting rod 3 to become a lever arm, which is convenient for pressing down the connecting rod 3 to pry the well cover. In order to make it more labor-saving to pry the well cover, the connecting rod 3 is set as a two-section lengthened structure. The connecting rod 3 is a two-section structure, and the two connecting rods 3 are connected by threads. The length of the connecting rod 3 increases, and it is more labor-saving to pry up the well cover. A fixing member 311 is arranged on the connecting portion 31. The fixing member 311 is threadedly connected to the connecting portion 31. The fixing member 311 is used to fix the steel rod 4. The fixing member 311 can pass through the surface of the connecting portion 31 and abut against the steel rod 4. After the steel rod 4 is inserted into the connecting portion 31, screwing in the fixing member 311 can fix it. Rollers 11 are respectively arranged on the left and right sides below the positioning member 1. After the well cover is pried up by the prying component, the support framework can roll backward through the rollers 11, which is convenient for pulling the support framework to move the well cover. A reinforcing member 6 is arranged between the positioning member 1 and the abutting member 2. The reinforcing member 6 can keep the positioning member 1 and the abutting member 2 stable, and at the same time can improve the load-bearing capacity of the abutting member 2.

[0024] Embodiment 2:

[0025] On the basis of the above embodiment, this embodiment further defines the well cover connection component 5, such as Figure 3As shown in the figure, the manhole cover connection assembly 5 includes a connection chain 51, a limiting member 52, a spring 53, and a retaining piece 54. Connection chains 51 are provided on both the left and right sides of the abutting member 2. The connection chain 51 is a metal chain link, and the connection chain 51 is movably connected to the abutting member 2. The limiting member 52 is provided below the connection chain 51 and is welded to the connection chain 51. A limiting portion 521 is provided below the limiting member 52. The limiting portion 521 is a strip-like structure, which can be inserted under the manhole cover through the kidney-shaped hole of the manhole cover. After manually rotating the limiting portion 521 inside the manhole cover, the manhole cover can be hooked. The retaining piece 54 and the spring 53 are sleeved on the limiting member 52 and are located between the limiting portion 521 and the connection chain 51. The retaining piece 54 is located at the end of the spring 53 and is arranged close to the limiting portion 521. When the limiting portion 521 hooks the manhole cover, by squeezing the retaining piece 54 through the spring 53, the retaining piece 54 and the limiting portion 521 can be made to approach each other, so that the limiting portion 521 can be kept stable inside the manhole cover, preventing the limiting member 52 from rotating again when prying the manhole cover, and thus the manhole cover can be stably lifted to prevent the manhole cover from falling; after the manhole cover is installed in place, manually press down the limiting member 52 and rotate it to make it disengage from the kidney-shaped hole of the manhole cover. Other parts of this embodiment are the same as those of the above embodiment and will not be elaborated here.
