Universal pulleys are arranged at the two ends of the base plate. Reinforcing rods are arranged between the two ends of the base plate and the vertical rods. The beam is an H-shaped steel rail. A monorail trolley is arranged on the beam. A lever block is connected to the lower portion of the monorail trolley. A cover plate lifting mechanism is hooked below a lifting hook of the lever block. According to the cover plate lifting device, the mechanical lifting device is adopted to replace a traditional manually-operated operating mode, workloads are reduced, and meanwhile safety is improved. The lifting device is of a door-shaped framework, the monorail trolley is utilized for being connected with the lever block, the lifting hook of the lever block hooks a cover plate to lift the cover plate, the monorail trolley is utilized for transversely moving the cover plate, the operation is easy and convenient, and the actual applicability is high. Meanwhile, a lifting hook plate adopted in the cover plate lifting device is in a plate shape, so that the contact area is increased, and the safety is higher.
Description
Technical field
The present invention relates to a kind of bont of cover plate, particularly the bont of cable work manhole cover plate.
Background technology
Along with the quickening of electrical network and Process of Urbanization Construction, being on the increase of cabling reconstructing engineering, cable line is also more and more.Rolling up of cable work well quantity, causes searching in cable line maintenance, prerun, trouble point, in the work such as path orientation, manually lifts that to remove the work capacity of cable work manhole cover plate increasing in the past.Meanwhile, manually lift and remove the Work tool simple and crude (crow bar, bamboo pole, crooked chisel, rope etc.) that heavy work manhole cover plate is used, safety factor is low, operating personnel is easily injured in lifting the process of removing, and, manually lift that to remove the operating personnel who uses in heavy work manhole cover plate process more, production time is longer.
Because cable cover is load-bearing cover plate, and used cement concrete jointing, between cover plate, friction force is large, and operating personnel is difficult to this cover plate to promote, to cable line maintenance, prerun, trouble point search, the work such as path orientation brought great inconvenience.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of high safety, efficiency cover plate bont high, easy and simple to handle.For this reason, the present invention is by the following technical solutions: it comprises door type framework, described door type framework comprises the crossbeam at top and two montants at crossbeam two ends, described montant bottom is provided with the base plate perpendicular to montant, described base plate two ends are provided with Universal pulley, and are provided with stirrup between base plate two ends and montant;
Described crossbeam is bull headction, on this crossbeam, be provided with hand cart, under described hand cart, be connected with Lever Blocks, this Lever Blocks is hand chain lever hoist, under the suspension hook of Lever Blocks, hang with cover plate lift system, described cover plate lift system comprises that one end is connected to two isometric steel wire covers on suspension hook and utilizes shackle to be connected to the suspension hook plate that can catch on cover plate draw ring of the steel wire cover other end.
Adopting on the basis of above technical scheme, the present invention can also adopt following further scheme:
Described drop hanger plate is tabular, and this suspension hook plate comprises the swash plate on top, the riser at middle part and the bottom transverse slat vertical with riser, and is welded with fixedly steel bar at the junction outside face of the junction of swash plate and riser outside face and riser and transverse slat.
Under described crossbeam, two ends are welded with respectively tube-like piece, and described two montants insert respectively in the tube-like piece at crossbeam two ends, and fix with long bolt.
The length of described crossbeam is 1300mm-1700mm.
The length of described montant is 1400mm-1800mm.
The length of described base plate is 600mm-1000mm.
Described Universal pulley is provided with brake gear.
Owing to having adopted technical scheme of the present invention, the present invention adopts mechanical type bont to replace traditional manual mode of operation, when reducing work capacity, has also promoted safety.Bont of the present invention adopts door type framework, utilizes hand cart to connect Lever Blocks, and Lever Blocks suspension hook promotes after living cover plate, utilizes hand cart by cover plate translation, and simple to operate, convenient, practical application is strong.Meanwhile, suspension hook plate of the present invention is tabular, has increased area of contact, makes safety higher.
Accompanying drawing explanation
Fig. 1 is overall schematic of the present invention.
Fig. 2 is lateral plan of the present invention.
Fig. 3 is the structural representation of montant of the present invention and Universal pulley.
Fig. 4 is the schematic diagram of suspension hook plate of the present invention.
The specific embodiment
Below in conjunction with Figure of description, the present invention will be further described.
The present invention includes door type framework 1, this framework adopts steel structure, and overall weight is heavier.Described door type framework 1 comprises the crossbeam 2 at top and two montants 3 at crossbeam 2 two ends, 2 times two ends of described crossbeam are welded with respectively tube-like piece 21, described two montants 3 insert respectively in the tube-like piece 21 at crossbeam two ends, and fix with long bolt, when installing and dismantle, only need to operate long bolt can realize, convenient disassembly, so although total quality is heavier, but its single parts can be realized dismounting, make carrying and carrying process light, comprise that the cucurbit of the following stated and hand cart 10 can dismantle.
Described montant 3 bottoms are provided with the base plate 4 perpendicular to montant 3, described base plate 4 two ends are provided with Universal pulley 5, and be provided with stirrup 6 between base plate 4 two ends and montant 3, four Universal pulleys 5 make bont can arbitrarily move and adjust position, meanwhile, Universal pulley all arranges brake is installed, after braking after fixing position, operation process change can not be affected, and application is strong, safe;
Described crossbeam 2 is bull headction, on this crossbeam 2, is provided with hand cart 10, hand cart 10 can be on crossbeam 2 parallel.Described hand cart is connected with Lever Blocks 11 10 times, this Lever Blocks 11 is hand chain lever hoist, the suspension hook of Lever Blocks 11 hangs with cover plate lift system 12 times, and described cover plate lift system comprises that one end is connected to two isometric steel wire covers 13 on suspension hook and utilizes shackle 20 to be connected to the suspension hook plate 14 that can catch on cover plate draw ring that steel wire overlaps 13 other ends.
