Description

Well lid opening tool

Technical Field

The utility model relates to a well lid apparatus field especially relates to a well lid opening tool.

Background

With the acceleration of the urbanization process, the well lid is used more and more frequently in the infrastructures such as water supply and drainage, communication, gas and power supply cables. When an underground pipe cable breaks down, a worker often needs to open a well cover for maintenance, generally, a common steel bar is adopted, one end of the common steel bar is bent into a hook, and the other end of the common steel bar is bent into a simple tool of a handle. Because the well lids are very heavy, the maintenance personnel spend a great deal of time and effort to open and move. Not only wastes time and labor, but also has the potential safety hazard of damaging and smashing the operating personnel.

Preferably, the lower part of the support frame is an internal thread, and the upper part of the base is an external thread corresponding to the internal thread of the support frame.

Preferably, the pedals are arranged at the lower part of the tripod to form a regular triangle.

Preferably, the lever is an antirust steel pipe, and a rubber sleeve with threads is sleeved at the handheld position of the first end of the lever.

Preferably, a rubber tire is arranged on a hub of the roller.

Preferably, the hooks are not less than 2 in number and different in specification.

The utility model provides an among the well lid opener, including lever, support frame, base and couple frame, the lever includes relative first end and second end, the couple frame welding is provided with the couple on the crossbeam of couple frame at lever second end, the support frame includes with the bracing piece that is close to the position articulated bearing of lever second end and upper portion and bearing welding, lower part and base threaded connection, the base includes footboard, tripod and sets up the universal wheel in every stabilizer blade lower part of tripod, the universal wheel includes gyro wheel and locker. When carrying out the well lid and opening the in-process, hang the well lid hole with the couple, close the locker and fix the gyro wheel, the footboard is stepped on to the foot, presses the first end of lever, and the well lid is easily mentioned under the leverage, only needs to rotate the lever when removing to one side, and the well lid removes to one side under the drive of bearing, when removing to other positions, opens the locker and can stimulate the well lid, reaches and opens and remove the laborsaving effect of well lid safety.

In the figure: the lever comprises a lever 1, a rubber sleeve 101, a sub hinge interface 102, a support frame 2, a female hinge interface 201, a bearing 202, a bearing upper portion 2021, a bearing lower portion 2022, a support rod 203, an internal thread 204, a base 3, an external thread 301, a tripod 302, a universal wheel 303, a roller 3031, a locker 3032, a pedal 304, a hook frame 4 and a hook 401.

Detailed Description

In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings required to be used in the embodiments will be briefly described below, and it is obvious that the drawings in the following description are some embodiments of the present invention, and it is obvious for those skilled in the art to obtain other drawings without creative efforts.

Referring to fig. 1 to 6, a manhole cover opening tool comprises a lever 1, a support frame 2, a base 3 and a hanger 4, wherein the lever 1 comprises a first end and a second end which are opposite, the hanger 4 is welded at the second end of the lever, a hook 401 is arranged on a cross beam of the hanger 4, the support frame 203 comprises a bearing 202 hinged to a position close to the second end of the lever 1 and a support rod 203 with an upper part welded to the bearing 202 and a lower part screwed to the base 3, the base 3 comprises a pedal 304, a tripod 302 and a universal wheel 303 arranged at the lower part of each support leg of the tripod 302, and the universal wheel 303 comprises a roller 3031 and a locking device 3032. When carrying out the well lid and opening the in-process, hang couple 401 and live the well lid hole, close locking ware 3032 and fix gyro wheel 3031, the footboard 304 is stepped on to the foot, press the first end of lever 1, because the arm of force is longer, the well lid is easily mentioned under lever 1 effect, only need rotate lever 1 when removing to one side, the well lid removes to one side under the drive of bearing 202, when removing to other positions, open locking ware 3032 and can stimulate the well lid, reach and open and remove the safe laborsaving effect of well lid.

In a preferred embodiment, the bearing upper portion 2021 is welded with the female hinge interface 201, the lever 1 is welded with the male hinge interface 102 at a position close to the second end, and the ratio of the length of the male hinge interface 102 from the first end of the lever 1 to the length of the female hinge interface from the second end of the lever 1 is 3.

Furthermore, the lower part of the support frame 2 is provided with internal threads, and the upper part of the base 3 is provided with external threads 301 corresponding to the internal threads 204 of the support frame 2. The base 3 and the support frame 2 are convenient to disassemble after construction is completed, and the occupied space is reduced.

Further, the pedals 304 are arranged at the lower part of the tripod 302 to form a regular triangle. The base 3 rotates to any position and can both step on footboard 304, need not readjust base 3, and regular triangle stability is strong simultaneously, can keep the stability of well lid migration in-process.

Further, lever 1 is rust-resistant steel pipe, improves life, and the department cover of holding of lever 1 first end is established and is taken threaded rubber sleeve 101, plays anti-skidding effect.

In a preferred embodiment the diameter of the rust resistant steel pipe is 60 mm.

Further, a rubber tire is arranged on a hub of the roller 3041, so that the ground contact friction force is increased.

Further, couple 401 is not less than 2, the different couple 401 of specification for the number to be applicable to different well lids.
