Description

A kind of large-scale well lid lifting appliance

Technical field

The utility model relates to a kind of large-scale well lid lifting appliance.

Background technology

At present, maintenance department is in order to overhaul underground utilities, must carry earlier and open cement well lid, and the most general method is exactly by manpower in the prior art, heavy then cement well lid upward ton leans on several staff to utilize lever principle with the well lid perk, and well lid lifted with hands and move realize moving of well lid position, carry out the upkeep operation of underground utilities again, after the completion, again well lid is lifted and retracts original position, so repetitiousness, the staff is time-consuming but also take muscle power not only, and it is few to put forward the quantity that opens well lid in one day, influences job schedule, and careless well lid can be warped and fractured.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned weak point of the prior art and provides a kind of simple in structure, large-scale well lid lifting appliance convenient to use.

The utility model realizes that in the following way the utility model is a kind of large-scale well lid lifting appliance, it is characterized in that: include support 1, Lever Blocks 2, cross bar 4, suspension ring 6; The cross bar middle part of described support 1 is installed with a shackle 11, and Lever Blocks 2 hooks shackle 11 makes Lever Blocks 2 hang over mid-stent; The middle part of described cross bar 4 is installed with shackle 9, and the other end suspension hook 3 of Lever Blocks 2 hooks shackle 9, makes suspension hook 3 and cross bar 4 to rise simultaneously.

Described support 1 bottom is provided with 4 wheels 5.

The two ends of described cross bar 4 are respectively equipped with protruding shelves 10.

The utility model utilizes suspension ring 6 to pass cross bar 4 and suspension ring 6 is positioned over the two ends of cross bar 4 respectively, because the two ends of cross bar 4 are respectively equipped with protruding shelves 10, the suspension ring 6 that therefore are positioned over cross bar 4 two ends just can slippage not go out cross bar 4; Suspension hook 3 ' on the suspension ring 6 hangs respectively is located at two reinforcing bar annulus that set firmly on the cement well lid, suspension hook 3 on the Lever Blocks 2 hooks the shackle 9 that sets firmly in the middle of the cross bar 4, the handle of rotation Lever Blocks 2 can be carried and open well lid and put down well lid, and promoting support 1 can move well lid.

Simple in structure, easy to use, the saving extensive work time of the utility model is a kind of desirable large-scale well lid lifting appliance.

The specific embodiment

The utility model specific embodiment now is described in detail in detail in conjunction with the accompanying drawings,

Embodiment one, and as shown in Figure 1 and Figure 2, the utility model is a kind of large-scale well lid lifting appliance, it is characterized in that: include support 1, Lever Blocks 2, cross bar 4, suspension ring 6; The cross bar middle part of described support 1 is installed with a shackle 11, and Lever Blocks 2 hooks shackle 11 makes Lever Blocks 2 hang over mid-stent; The middle part of described cross bar 4 is installed with shackle 9, and the other end suspension hook 3 of Lever Blocks 2 hooks shackle 9, makes suspension hook 3 and cross bar 4 to rise simultaneously.

Described support 1 bottom is provided with 4 wheels 5.

The utility model utilizes suspension ring 6 to pass cross bar 4 and suspension ring 6 is positioned over the two ends of cross bar 4 respectively, because the two ends of cross bar 4 are respectively equipped with protruding shelves 10, the suspension ring 6 that therefore are positioned over cross bar 4 two ends just can slippage not go out cross bar 4; Suspension hook 3 ' on the suspension ring 6 hangs respectively is located at two reinforcing bar annulus that set firmly on the cement well lid, suspension hook 3 on the Lever Blocks 2 hooks the shackle 9 that sets firmly in the middle of the cross bar 4, the handle of rotation Lever Blocks 2 can be carried and open well lid and put down well lid, and promoting support 1 can move well lid.After the down-hole engineering is finished, when support 1 is pushed back the original position of well lid, rotate the handle of Lever Blocks 2 and well lid can be put back to original position.

Embodiment two, as shown in Figure 3, suspension ring 6 in the utility model can replace with suspension ring 7, in actual use, have an osculum on the round manhole cover 8, with the parallel osculum of putting into of the other end block of suspension ring 7, again with the baffle plate traverse, the suspension hook 3 of Lever Blocks 2 is hooked suspension ring 7, up carry opening and get final product.

In the utility model, the shape of suspension ring 7 other end blocks can be made amendment according to actual needs, such as the triangle that stands upside down etc.
