Description

Technical Field

[0001] The utility model relates to the technical field of gate well maintenance, in particular to a gate well maintenance and repair equipment. Background Art

[0002] During the gas inspection process, the opening of the manhole cover in winter and after the rainy season takes the longest time, and the time increase is the largest compared to normal times. Other operations basically take the same time as usual. In the process of opening the manhole cover, especially in winter when the manhole cover is frozen, it is difficult to open it with a conventional well trench and takes a long time, about 15 minutes, which greatly affects the efficiency of the inspection. In particular, there is a concern that it will seriously affect the efficiency of emergency repairs during the rescue and repair process, causing increased difficulty in emergency repairs or increased injuries to personnel and property damage. At the same time, when the manhole cover is not opened smoothly, personnel may pull too hard, causing falls and strains.

[0003] The traditional method of opening a manhole cover is to use a copper hammer to knock on the manhole cover to loosen the cover and the gate well, and then use a hook to hook one side of the manhole cover and pull it out. Since there is mud and sewage between the manhole cover and the gate well, a large amount of adsorption occurs. Manual hard pulling is not only likely to cause personal injury, but also has a low efficiency in opening the gate well. Utility Model Content

[0004] The purpose of the utility model is to provide a maintenance and inspection equipment for a gate well, which comprises a movable lever composed of a support frame and a pry bar, one end of the pry bar is connected to the well cover by a hook, and the other end is manually pressed, which can save effort and avoid hand injuries to workers, thereby improving the efficiency of opening the gate well cover and solving the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a gate well maintenance and repair equipment, comprising:

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example 1

[0024] The utility model provides Figures 1-2 A gate well maintenance and repair equipment shown in the figure comprises: a hook 1, a support frame and a pry bar 2. The support frame comprises a support base 3, support columns 4 are fixed on both sides of the top of the support base 3, a support seat 5 is movably provided on the top of the support column 4, a movable column 6 is movably provided in the inner cavity of the support seat 5, a through hole 7 is opened at the center of the movable column 6, and the pry bar 2 is located in the inner cavity of the through hole 7.

[0025] The support base 3 and the support seat 5 are connected by the support column 4, which is convenient for limiting the movable column 6. With the movable column 6 as the fulcrum and the pry bar 2 as a lever, the manhole cover 17 can be pried up from the inside of the gate well mouth 16 with a smaller force by utilizing the lever principle. This not only shortens the time for prying up the manhole cover 17, but also avoids the risk of manual hand injury.

[0026] A limiting groove 8 is provided at the top of the support column 4, and limiting blocks 9 are fixed on both sides of the bottom of the support seat 5. The limiting blocks 9 extend to the inner cavity of the limiting groove 8 and are clamped with the limiting groove 8. The clamping connection between the limiting blocks 9 and the limiting groove 8 ensures the stability of the support seat 5, thereby preventing the support seat 5 from shaking on the top of the support column 4 when one end of the pry bar 2 is pressed, thereby affecting the overall stability of the device.

[0027] An arc-shaped slot 10 is provided at the bottom of the support base 3 for snapping into the gate well mouth 16. The setting of the slot 10 facilitates the installation of the support base 3 at the gate well mouth 16, thereby preventing the entire device from sinking when the pry bar 2 is pressed, and preventing the support base 3 from having insufficient supporting force.

[0028] A nut 15 is welded to one end of the hook 1 , and one end of the pry bar 2 passes through the nut 15 and bends and extends outwards. The nut 15 is provided to facilitate the connection between the pry bar 2 and the hook 1 .

[0029] It also includes a manhole cover 17 located inside the gate well opening 16 , and the hook 1 passes through a through hole on the manhole cover 17 and extends into the gate well opening 16 .

[0030] Example 2

[0031] like Figure 3-4 As shown, a gate well maintenance and repair equipment includes: a hook 1, a support frame and a pry bar 2. The support frame includes a support base 3, support columns 4 are fixed on both sides of the top of the support base 3, a support seat 5 is movably arranged on the top of the support column 4, and a movable column 6 is movably arranged in the inner cavity of the support seat 5, a through hole 7 is opened at the center of the movable column 6, and the pry bar 2 is located in the inner cavity of the through hole 7, and the two sides of the top of the support base 3 are rotatably connected with a rotating shaft 11 through a bearing, and a cavity is opened inside the support column 4. The top of the rotating shaft 11 penetrates into the cavity and is fixed with a threaded sleeve 12, and the threaded sleeve 12 fits the inner wall of the cavity, and threaded rods 13 are fixed on both sides of the bottom of the support seat 5. One end of the threaded rod 13 away from the support seat 5 penetrates into the cavity and is threadedly connected with the threaded sleeve 12, and the inner cavity of the support base 3 is provided with an adjusting component 14 for driving the rotating shaft 11, so as to adjust the height of the support seat 5 to avoid that there is not enough space around the gate well mouth 16 to press the pry bar 2, and the pry bar 2 can be directly lifted as a whole, and the manhole cover 17 can still be pried up.

[0032] The adjusting assembly 14 includes a worm gear 141, which is fixedly connected to one end of the rotating shaft 11 away from the threaded sleeve 12. The inner cavity of the supporting base 3 is rotatably connected to a worm 142 through a bearing. The worm 142 is meshed with the opposite side of the worm gear 141. Both ends of the worm gear 142 extend outward through the supporting base 3 and are fixed with a rotating handle 143. The worm gear 141 is driven to rotate by the worm gear 142 to drive the rotating shaft 11, so that the two groups of rotating shafts 11 rotate synchronously and drive the threaded sleeve 12 to rotate. The threaded rod 13 is threadedly connected to the threaded sleeve 12, and the threaded rod 13 can be raised and lowered to adjust the height of the supporting base 5.

[0033] During specific use, the support base 3 is connected to the edge of the gate well mouth 16 through the card slot 10, and then the movable column 6 is placed in the support seat 5, and then the pry bar 2 is passed through the through hole 7, and then the hook 1 is inserted under the manhole cover 17 through the through hole, and one end of the pry bar 2 is passed through the nut 15. The manhole cover 17 can be pried up by manually pressing the other end of the pry bar 2. When there is not enough space around the gate well mouth 17, the pry bar 2 can be pressed down, and the turning handle 143 can be rotated to drive the worm 142 to rotate, and the worm gear 141 drives the rotating shaft 11. The rotating shaft 11 drives the threaded sleeve 12 to rotate, so that the threaded rod 13 moves upward in the threaded sleeve 12, and the threaded rod 13 is used to lift the support seat 5. At this time, the pry bar 2 pulls the manhole cover 17 upward through the hook 1, and the manhole cover 17 can still be pried up from the gate well mouth 16.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
