Preferably, described vehicle frame comprises a top cross bar, four braces, two cross tubes parallel to each other, four montants and two sheer poles parallel to each other, described top cross bar and cross tube parallel to each other, described cross tube and sheer pole orthogonal, be fixedly connected with by four braces between described top cross bar and two cross tubes, described Hand operating hoist is installed on the cross bar of top, the two ends of described two cross tubes are welded with the upper end of four montants respectively, the two ends of described two sheer poles are welded with the lower end of four montants respectively, and described cardan wheel is located at bottom sheer pole.Vehicle frame surrounds railing mainly through the connection of cross bar and montant, forms certain space, facilitates the suspension of Hand operating hoist, also conveniently sling after cable well lid, dolly is in moving process, and well lid remains within the railing of vehicle frame, in order to avoid staff is injured by a crashing object because of carelessness.
Preferably, described top cross bar is socketed with and along the annulus of movement on the cross bar length direction of top, the hook for hooking described Hand operating hoist bottom described annulus, can be fixed with.Cable shaft tops is generally provided with two draw rings for opening, opener of the present invention, top cross bar can arrange two or more annulus, and such vehicle frame can hang two Hand operating hoists, hook the draw ring on well lid respectively, well lid is opened and slings.Annulus for hanging Hand operating hoist can move on the cross bar of top, facilitates the distance between adjustment two Hand operating hoists, the distance of the draw ring that corresponding cable shaft covers, is applicable to the unlatching of various different cable well lid and the operation such as to sling.
Preferably, described sheer pole upper surface is provided with the placement plate for placing cable well lid.Cable well lid is sling after certain altitude by Hand operating hoist, plate will be placed through above sheer pole, be erected at sheer pole upper surface, and then well lid will be placed on and place on plate, carry out promotion vehicle frame again, prevent from well lid to be suspended on carrying out moving below Hand operating hoist and cause whipping to wound staff.With promote compared with dolly under well lid suspension status, well lid is placed on and places that plate to carry out promotion dolly safer.
Preferably, described vehicle frame is provided with the handrail for staff's hand push.Due to dolly and cable well lid heavier, carry out promotion dolly by handrail convenient laborsaving, greatly alleviate the labour intensity of staff.
The invention discloses a kind of trolley type cable manhole cover opener, Hand operating hoist is adopted to open and cable well lid of slinging, and by dolly, the cable well lid sling is moved, change the present situation that prior art manually opens cable well lid, planning is maked an inspection tour more rationally with effective to cable, substantially increases the efficiency that cable is maked an inspection tour, greatly alleviate the labour intensity of staff, avoid staff to move in cable well lid process injured at manpower simultaneously, ensure the personal safety of staff.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the invention will be further described:
Fig. 1 is the structural representation of a kind of trolley type cable of the present invention manhole cover opener embodiment 1;
Fig. 2 is the structural representation of a kind of trolley type cable of the present invention manhole cover opener embodiment 2.
Detailed description of the invention
As shown in Figure 1, be the preferred embodiment 1 of a kind of trolley type cable of the present invention manhole cover opener, comprise vehicle frame, be provided with the cardan wheel 5 of described bottom of frame and be installed on the Hand operating hoist 7 for cable well lid of slinging on described vehicle frame.The present invention adopts Hand operating hoist 7 as opening and the key fitment of cable well lid of slinging, and Hand operating hoist 7 hangs on vehicle frame, and drives vehicle frame to move by the cardan wheel 5 of bottom of frame, is removed by cable well lid, overhauls to facilitate staff to cable.Change prior art and need artificial present situation of opening cable well lid, by adopting Hand operating hoist 7 to liberate manpower, can easily heavy cable well lid be opened and sling, avoid staff to move in cable well lid process injured at manpower.
