Abstract

The utility model provides a multipurpose miniature hoister, which is in order to provide a miniature electric hoister for builders of building floor decoration, building roof maintenance and external wall painting to transport material to a high layer construction site or countryside to transport grain or economic crop to a building roof. The utility model is characterized in that the multipurpose miniature hoister is composed of a material lifting hook 1, a lifting rope 2, a fixed pulley 3, a lifting arm assembly 4, a rope tensioning assembly 5, an upper center support rod 6, a cross joint 7, a miniature electric winding engine assembly 8 which is arranged on a balance arm, a balance arm assembly 9, a counterweight pull rope 10, a lifting hook 11 and a support frame assembly 12. The multipurpose miniature hoister can be arranged on a building roof, and can also be arranged in a room. Support frames of the multipurpose miniature hoister not need to be anchored with the ground. When the multipurpose miniature hoister is worked in a room, the lifting arm can be extended to outside from a window. Counterweight objects can be arranged on site, and do not need to carry with the multipurpose miniature hoister. The utility model can largely reduce labor strength, and has the advantages of safety, simple structure, light weight, convenient carrying and easy assembly and disassembly.

Description

The small-sized gig of high-mobility, multipurpose, wheeled vehicle

Technical field: the utility model belongs to light weight small-sized material elevating gear.

Background technology: people in room (building) top or the high-rise room of building, be engaged in dimension (dress) study in a school affair or because of other need be when work-site transports material, known method (technology) is: perhaps all rely on manpower, perhaps take raising legs on ground, perhaps pacify pulley yoke at the construction field (site), or other home-built equipment.The shortcoming of above method is: the structure heaviness, the labour is heavy, use cost height, safety inadequately.Known to the designer, also there is not the small-sized elevating gear of standard to be used for above-mentioned work-site at present.

Summary of the invention: the purpose of this utility model is according to principle of moment balance, manufactures and designs a kind of lightly, small-sized, parts can be taken to the small-sized gig of high-mobility, multipurpose, wheeled vehicle that can devote oneself to work after high-rise work-site is assembled easily.The technical scheme that the utility model is taked is: 1, whole frame adopts steel pipe to make the socket joint connection, can make up easily or take apart; 2, small-sized electric winch assembly is installed on the equilibrium arm; 3, the lift arm assembly is connected with the X conn socket joint with the balance arm assembly; 4, lift arm is connected with last centre post upper end with the tension rope respectively with the equilibrium arm two ends, and the tension back can prevent lift arm and balance brachiocylloosis under load condition; 5, in the equilibrium arm assembly, right-hand member is equipped with wheeled strut bar, guarantees that the mass that is suspended on the equilibrium arm does not land; 6, bracing frame adopts three-legged structure, and the angle socket joint that every supporting leg and carriage center line options are suitable is connected, and entire bracket maintenance under the situation that need not be anchored with ground is stablized.

Description of drawings: accompanying drawing is the utility model scheme drawing.Among the figure: 1. material suspension hook 2. hoisting ropes 3. fixed pulley assemblies 4. lift arm assemblies 5. are strained centre post 7. X conns 8. small-sized electric winch assemblies 9. equilibrium arm assemblies 10. counterweight stay cords 11. suspension hooks 12. bracing frame assemblies on the rope assemblies 6.

The specific embodiment: describe the utility model embodiment below in conjunction with embodiment machine accompanying drawing.In the accompanying drawing: bracing frame (12) supporting leg is made with steel pipe, selects for use proper angle to distribute, and is connected with the short sleeve socket joint of three directions on being welded in the carriage center sleeve pipe, forms a stable whole framework, is connected with X conn (7) socket joint above it.X conn (7) can parallel steer, and its left side is connected with lift arm assembly socket joint, and the right is connected with equilibrium arm assembly socket joint, respectively uses bolt after the connection.In order to make the convenient vanning of member, its lift arm and equilibrium arm respectively make with two joint steel pipes and socket joint is connected.Lift arm is connected with last central support tube (6) upper end with rope with the equilibrium arm two ends, can adjust its elasticity simultaneously, to improve integral frame intensity.At the equilibrium arm right-hand member wheeled strut bar is housed, its effect is that supported and suspended mass on equilibrium arm does not land.With bolt one bed plate, the small-sized electric winch is fixed in the above on the equilibrium arm.The small-sized electric winch is made of electrical motor, reductor and the reel that is installed on the reductor.Electrical motor drives work such as reductor and reel by coupler.
