Abstract
The utility model relates to a manual wall-type cantilever crane comprising a rotary arm beam, an electric hoist, a hand brake, a hand brake suspension link, a rotating suspension link and a rotating shaft, wherein the rotating shaft is arranged on the wall surface through a support seat; the axis of the rotating shaft is in the vertical direction; one end of the rotary arm beam is arranged on the rotating shaft; the rotary arm beam is vertical to the axis of the rotating shaft; the rotating suspension link is connected with the rotary arm beam through a stay wire; the electric hoist is arranged on a slide rail of the rotary arm beam; the hand brake is arranged on the bracket through a spring rotating shaft; the friction surface of the hand brake tightly leans against a brake block on the rotating shaft; the hand brake suspension link is connected with one end of the hand brake, far away from the rotating shaft, through the stay wire. By adopting the manual wall-type cantilever crane, the manual rotation of a cantilever is achieved by matching of the hand brake suspension link and the rotating suspension link, and the manual wall-type cantilever crane is simple in structure, convenient and safe to use.
Description
Technical field
The utility model relates to a kind of manually wall formula boom crane.
Background technology
Boom crane is made up of hinged cantilever, electric block and electrical controller etc., existing boom crane complete machine weight compared with large, consumptive material is many, energy consumption is high, electric feeding device installation and maintenance inconvenience.The Chinese utility model patent of CN202322035 discloses a kind of structure of fixing electricity donor device on fixed-column type cantilever crane, the electric feeding device of this patent is arranged in girder, electric feeding device must successively just can be arranged in column top through after the square hole of girder web plate, lower cover and lower flange, and difficulty, inconvenient maintenance are installed.The Chinese utility model patent of CN202296897 discloses a kind of Split column suspension crane, and its pivot arm is provided with extension rail, hangs on rail the gig that can walk is installed, and pivot arm tail end is provided with bearing carrier ring, and bearing carrier ring is arranged in axle by bearing.Extension rail one end of this pivot arm only has downside one place to be bearing on column termination by bearing, in the time that gig is positioned at extension rail other end termination handling article, hang rail and column and be subject to moment of flexure all in the time of maximum position, hang the easy run-off the straight of rail, pivot arm rotation difficulty.
Utility model content
The purpose of this utility model is to provide a kind of manually wall formula boom crane, solves the above-mentioned problems in the prior art.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of manually wall formula boom crane, comprise spiral arm beam, electric block, parking brake, parking brake draw ring, rotate draw ring and rotating shaft, described rotating shaft is arranged on metope by bearing, the axis of described rotating shaft is vertical direction, one end of described spiral arm beam is arranged in described rotating shaft, described spiral arm beam is perpendicular to the axis of described rotating shaft, described rotation draw ring is connected with described spiral arm beam by bracing wire, and described electric block is arranged on the slide rail of described spiral arm beam;
Described parking brake is arranged on described support by spring rotary shaft, and the friction face of described parking brake abuts against on the brake shoes in described rotating shaft, and described parking brake draw ring is connected away from one end of described rotating shaft with described parking brake by bracing wire.
Further, on described spiral arm beam, be also provided with pull bar, one end of described pull bar is fixed in described rotating shaft, and the other end is fixed on described spiral arm beam.
The beneficial effects of the utility model are: the utility model provides a kind of manual wall formula boom crane, realize the manual rotation of cantilever by the cooperation of parking brake draw ring and rotation draw ring, simple in structure, safety easy to use.
Accompanying drawing explanation
Fig. 1 is a kind of manually wall formula boom crane structural representation of the utility model.
In accompanying drawing, the list of parts of each label representative is as follows:

The specific embodiment
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
As shown in Figure 1, a kind of manually wall formula boom crane, comprise spiral arm beam 3, electric block 4, parking brake 10, parking brake draw ring 8, rotate draw ring 6 and rotating shaft 1, described rotating shaft 1 is arranged on metope 14 by bearing 12, the axis of described rotating shaft 1 is vertical direction, one end of described spiral arm beam 3 is arranged in described rotating shaft 1, described spiral arm beam 3 is perpendicular to the axis of described rotating shaft 1, described rotation draw ring 6 is connected with described spiral arm beam 3 by bracing wire 5, and described electric block 4 is arranged on the slide rail of described spiral arm beam 3;
Described parking brake 10 is arranged on described support 12 by spring rotary shaft 11, and the friction face of described parking brake 10 abuts against on the brake shoes 13 in described rotating shaft 1, and described parking brake draw ring 8 is connected away from one end of described rotating shaft 1 with described parking brake 10 by bracing wire 9.On described spiral arm beam 3, be also provided with pull bar 2, one end of described pull bar 2 is fixed in described rotating shaft 1, and the other end is fixed on described spiral arm beam 3.
When work, need two people to coordinate the rotation of spiral arm beam 3, staff's first pulls parking brake draw ring 8, make described parking brake 10 depart from described brake shoes 13, staff's second pulls rotation draw ring 6 to make spiral arm beam rotate to assigned address, staff's first is unclamped parking brake draw ring 8, the fixing assigned address of spiral arm beam 3.
The utility model is realized the manual rotation of cantilever by the cooperation of parking brake draw ring and rotation draw ring, simple in structure, safety easy to use.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
