In order to solve the technical problem, the utility model provides a technical scheme as follows: a cover opening device for an inspection well difficult to open comprises an installation base, wherein three support legs are uniformly distributed on the installation base along the circumferential direction and are respectively and movably connected with the installation base in a rotating mode; the length of the three support legs is adjustable; the three support legs comprise a rear support leg and two front support legs, and an operation space is formed between the two front support legs; connecting rods are respectively arranged between the rear supporting leg and the two front supporting legs, and the connecting rods are respectively hinged with the front supporting leg and the rear supporting leg; the connecting rod comprises a first rod section and a second rod section, and the first rod section is hinged with the second rod section; the well opening hook is detachably connected with the lower end of the mounting seat; the well opening hook is detachably connected with the hanging hook of the chain block.

When the well lid is opened, the three support legs are unfolded respectively, and the first rod section and the second rod section are located on the same straight line. The well lid is located between three landing leg, adjusts the length of three landing leg according to the topography condition of job site. And then, the constructor installs the chain block and the well opening hook from the operation space, reliably connects the well opening hook with the well lid, and finally gradually opens the well lid through the chain block.

The distribution of three landing legs and the setting of connecting rod when guaranteeing to support the reliability, have left sufficient space for the construction operation. The chain block can be lifted by smaller pulling force, and the well lid opening efficiency is good for the well lid difficult to open. The cover opening device has the advantage of simple structure, is convenient to carry, and is suitable for mobile construction.

Preferably, the lower ends of the three support legs are respectively provided with a walking wheel, and after the well cover is opened, the well cover can be horizontally moved together with the cover opening device.

Preferably, the supporting leg comprises a connecting section and a telescopic section, the telescopic section is inserted into the connecting section and is in sliding connection with the connecting section along the length direction, and a fastening device is arranged between the connecting section and the telescopic section; the connecting section is connected with the mounting seat.

Preferably, the fastening device comprises a set screw arranged at the connecting section; and a plurality of limiting holes matched with the set screws are distributed on the telescopic section along the length direction.

Drawings

Fig. 1 is a schematic structural diagram of a cover opening device for a difficult-to-open inspection well in the embodiment;

fig. 2 is a top view of the uncapping device for a difficult-to-open inspection well according to the embodiment.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Examples

As shown in fig. 1 and 2, the cover opening device for the inspection well difficult to open comprises a mounting base 1, wherein three support legs are uniformly distributed on the mounting base 1 along the circumferential direction and are respectively and movably connected with the mounting base 1 in a rotating mode. The lower extreme of three the landing leg is equipped with walking wheel 4 respectively, after opening well lid 8, can be with well lid 8 together horizontal migration with the device of uncapping.

As shown in fig. 1 and 2, the leg includes a connecting section 51 and a telescopic section 52, the telescopic section 52 is inserted into the connecting section 51 and slidably connected with the connecting section 51 along a length direction, and a fastening device is disposed between the connecting section 51 and the telescopic section 52. The connecting section 51 is connected with the mounting base 1. The fastening device comprises a set screw arranged on the connecting section 51, and a plurality of limiting holes matched with the set screw are distributed on the telescopic section 52 along the length direction.

As shown in fig. 1 and 2, the three legs include a rear leg 53 and two front legs 54, an operation space 7 is formed between the two front legs 54, and a connecting rod 6 is respectively disposed between the rear leg 53 and the two front legs 54.
