Abstract

The utility model provides an inspection well cover opening device which comprises a chain and a crowbar. Two ends of the chain are provided with hook bodies I, wherein the hook bodies I are used for being matched with a well cover plate to hook the well cover plate. The front end of the crowbar is provided with a hook body II, wherein the hook body II is used for hooking the chain. A universal wheel assembly is arranged on the crowbar. The crowbar uses the universal wheel assembly to be a support to raise the chain. When the inspection well cover opening device is used for opening a well cover, damage cannot occur easily, opening of the well cover is time-saving and labor-saving, and the well cover is convenient to uplift and move.

We usually will come into contacts with various all kinds of well lid in routine duties, and the unlatching of well lid becomes problem of comparatively having a headache in our work.General well lid is opened with crowfoot or rope.Be difficult for opening with rope, if the words of opening well lid with crowfoot etc. then can cause to a certain degree damage to well lid, time one length must influence well lid intensity and attractive in appearance.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of inspection shaft lid opening device, is difficult for causing damage when opening well lid, and it is time saving and energy saving that well lid is opened, and well lid lifts conveniently moving.

For solving above-mentioned existing technical matters, the utility model adopts following scheme: a kind of inspection shaft lid opening device, comprise chain and crowbar, described chain two ends are equipped with for cooperate hook to live the coupler body I of well lid plate with the well lid plate, the front end of described crowbar is provided with the coupler body II for the hook chain, described crowbar is provided with universal wheel component, and described crowbar is to support to provoke chain with the universal wheel component.

As preferably, described coupler body I is T type hook.

As preferably, described T type hook comprises body of rod I, body of rod II and loop bar, and described body of rod I one end is connected chain ends, other end switching at body of rod II middle part, described loop bar be set on the body of rod I and with body of rod I screw thread fit.

As preferably, described crowbar is provided with direction pipe link down, and described universal wheel component comprises cardan wheel and the Universal castor that cooperates with cardan wheel, and described Universal castor top is provided with the sleeve pipe with the pipe link socket.

As preferably, described sleeve pipe is provided with bolt, and described bolt cooperates in the precession sleeve pipe with casing threads outside sleeve pipe and withstands on the pipe link.

As preferably, described Universal castor is provided with 2 cardan wheels.

As preferably, described crowbar front end is provided with the montant that is directed upwardly, and described coupler body II is formed by the angle of cut of crowbar and montant.

Beneficial effect:

A kind of inspection shaft lid opening device that the utility model adopts technique scheme to provide is difficult for causing damage when opening well lid, it is time saving and energy saving that well lid is opened, and well lid lifts conveniently moving.

Fig. 4 is the structural representation of the utility model universal wheel component.

The specific embodiment

Shown in Fig. 1 to 4, a kind of inspection shaft lid opening device, comprise chain 2 and crowbar 1, described chain 2 two ends are equipped with for cooperate hook to live the coupler body I 3 of well lid plate with the well lid plate, the front end of described crowbar 1 is provided with the coupler body II for hook chain 2, described crowbar 1 is provided with universal wheel component 5, and described crowbar 1 serves as to support to provoke chain 2 with universal wheel component 5.Described coupler body I 3 is T type hook.Described T type hook comprises body of rod I 31, body of rod II 32 and loop bar 33, and described body of rod I 31 1 ends are connected chain 2 ends, the other end is transferred at body of rod II 32 middle parts, described loop bar 33 be set on the body of rod I 31 and with body of rod I 31 screws thread fit.Described crowbar 1 is provided with direction pipe link 11 down, and described universal wheel component 5 comprises cardan wheel 51 and the Universal castor 52 that cooperates with cardan wheel 51, and described Universal castor 52 tops are provided with the sleeve pipe 53 with pipe link 11 sockets.Described sleeve pipe 53 is provided with bolt 54, described bolt 54 outside sleeve pipe 53 with sleeve pipe 53 screw thread fit precession sleeve pipes 53 in and withstand on the pipe link 11.Described Universal castor 52 is provided with 2 cardan wheels 51.Described crowbar 1 front end is provided with the montant 4 that is directed upwardly, and described coupler body II is formed by the angle of cut of crowbar 1 and montant 4.

Pipe link 11 on the crowbar 1 is overlapped in the sleeve pipe of receiving on the Universal castor 52 53, the T type hook at chain 2 two ends is hooked respectively in two perforates of well lid plate, then the front end of crowbar 1 being passed chain 2 makes chain 2 hang over the angle of cut place of crowbar 1 and montant 4, namely can universal wheel component 5 lever up the well lid plate for supporting this moment, move the well lid plate that is levered up by universal wheel component 5 then, regulate bolt 54 and can make bolt 54 hold out against or leave pipe link 11, can regulate pipe link 11 and the socket length of sleeve pipe 53 and then the bearing height of adjusting crowbar 1 like this.The concrete operations that T type hook hooks in the perforate of well lid plate are as follows: earlier with loop bar 33 spin-ups, rotating body of rod II 32 makes body of rod I 31 and body of rod II 32 parallel and stretch into together in the perforate of well lid plate, screwing off loop bar 33 again makes loop bar 33 hold out against body of rod II 32, this moment, body of rod I 31 and body of rod II 32 vertical hooks were in the perforate of well lid plate, difficult drop-off.
