The lifting capacity of the manual hoist is fully utilized, and the model of the manual hoist can be changed according to the weight of the manhole cover. After the manhole cover is lifted, it can be carried horizontally, and one person can complete the opening and transportation of a large manhole cover. The utility model has the advantages of low manufacturing cost, wide application, safety, reliability, durability, good performance, easy maintenance, small volume, light weight, reduced labor and high efficiency.

In order to achieve the above object, the utility model adopts the following technical solutions:

A manhole cover handling device, comprising a trolley frame and a manual hoist, the upper hook of the manual hoist is connected to the crossbeam of the trolley frame, and also includes a chain and a steel hook, the middle part of the chain is hooked on the lower hook of the manual hoist, Steel hooks are fixed at both ends of the chain, and when the manhole cover is transported, the two steel hooks are respectively inserted into the two through holes of the manhole cover to hook the manhole cover.

The trolley frame includes outriggers, beams, lower connecting beams, upper connecting beams, and universal wheels. The lower parts of the four supporting legs are connected into an integral structure through the lower connecting beams, and the upper ends of the two supporting legs on the same side pass through the upper The connecting beam is connected, the beam is fixed at the middle position of the two upper connecting beams, and universal wheels are installed at the bottom ends of the four supporting legs.

A circular ring is arranged on the steel hook, and the steel hook is fixedly connected with the chain through the circular ring.

Compared with the prior art, the beneficial effects of the utility model are:

Detailed ways

The utility model is described in detail below in conjunction with the accompanying drawings, but it should be pointed out that the implementation of the utility model is not limited to the following embodiments.

As shown in Figures 1-2, a manhole cover handling device includes a trolley frame, a manual hoist 1, the upper hook of the manual hoist 1 is connected to the crossbeam 6 of the trolley frame, and also includes a chain 4 and a steel hook 5. The middle part of the chain 4 is hooked on the lower hook of the manual hoist 1, and steel hooks 5 are fixed at both ends of the chain 4. When the manhole cover 3 is transported, the two steel hooks 5 are respectively inserted into the two through holes of the manhole cover 3 to hook manhole cover 3.

Described trolley frame comprises supporting leg 2, crossbeam 6, lower connecting beam 8, upper connecting beam 9, universal wheel 7, the bottom of four supporting legs 2 is connected as an integral structure by lower connecting beam 8, two on the same side The upper end of each supporting leg 1 is connected by upper connecting beam 9, crossbeam 6 is fixed on the middle position of two upper connecting beams 9, and universal wheel 7 is installed at the bottom of four supporting legs 2.

The trolley frame is a steel structure frame welded by steel plates.

Steel hook 5 is processed by round steel.

A circular ring 10 is arranged on the steel hook 5 , and the steel hook 5 is fixedly connected with the chain 4 through the circular ring 10 .

When carrying the well cover 3, a well cover handling device of the present utility model is pushed to the upper end of the well cover 3, and two steel hooks 5 are respectively inserted from the two through holes on the well cover 3, and the steel hooks 5 are hooked to the well cover 3. Move the trolley frame so that the chain 4 is placed directly above the manhole cover, then start the manual hoist 1 to slowly tighten the chain 4, continue to move and adjust the position of the trolley frame so that the lower hook of the manual hoist 1 is placed on the manhole cover 3 Just above the center point of the through-hole connection, so that the chains 4 on both sides are evenly stressed. Finally, under the lifting action of the manual hoist 1, the manhole cover 3 is started. After the manhole cover 3 is lifted to a certain height, the manual hoist 1 is stopped and slowly Push the trolley frame to move the well cover 3 away from the top of the well position.

After the construction is completed or the replacement of the well cover is completed, the well cover 3 can be slowly translated back to the top of the well position, so that the well cover 3 can fall back on the well position. During operation, it should be noted that the well cover 3 in the suspended state will be aligned with the well position.
