Abstract
The invention relates to the technical field of lifting, in particular to a boom structure; the boom structure is simple in structure, convenient to process and assemble, and is capable of lifting materials for different distances without lifting a boom. The boom structure comprises a boom; the upper end of the boom is provided with a lifting winch; the head part of the boom is fixedly provided with a first guide pulley; the lower end of the first guide pulley is provided with a movable guide pulley installation seat; the guide pulley installation seat is provided with a second guide pulley; a T-shaped fixing groove is formed in the bottom part of the boom; the guide pulley installation seat is provided with a fixture block matched with the T-shaped fixing groove; the lower end of the boom is fixedly provided with a telescopic oil cylinder; a piston rod of the telescopic oil cylinder is connected with the guide pulley installation seat; the fixture block is embedded into the T-shaped fixing groove; one end of a lifting rope is connected with the lifting winch; and after penetrating through the first guide pulley and the second guide pulley, the other end of the lifting rope is connected with a lifting hook.
Description
Technical field
The present invention relates to hoisting and hanging technical field, be specially a kind of boom structure.
Background technology
In material handling field, isolated pillar crane is the handling machinery that one of which is important, it can complete feeding, migration, the operations such as unloading, in ship equipment, isolated pillar crane is main handling machinery, the arm of isolated pillar crane completes the lifting carrying of material, arm is generally divided into regular length and telescopic, regular length generally can only lift material much the same with length of boom, for some from arm base close together, arm can only be raised and complete lifting, when arm is lifted more high, during lifting material, load-bearing requirements needed for suspension arm support is become big, when material is overweight, easily the oil cylinder of arm and support arm is caused damage, and telescoping boom can complete the material lifting of different distance, but the structure of arm is complex, processing inconvenience.
Summary of the invention
In order to solve the problems referred to above, the invention provides a kind of boom structure, its simple in construction, process and assemble is convenient, it is not necessary to raises arm and can realize the lifting of different distance material.
Its technical scheme is such that a kind of boom structure, it is characterized in that, it includes arm, hoister winch is installed in described arm upper end, described arm head fixedly mounts the first directive wheel, removable guide wheel mounting seat is installed in described first directive wheel lower end, described directive wheel mounting seat installs the second directive wheel, T-shaped draw-in groove is had bottom described arm, described second guiding wheel seat installs the fixture block with described T-shaped card slot fit, described arm lower end fixed installation telescopic oil cylinder, the piston rod of described telescopic oil cylinder connects described directive wheel mounting seat, described fixture block card is embedded in described T-shaped draw-in groove, lifting rope one end is connected with described hoister winch, the other end sequentially passes through described first directive wheel, connecting shackle after second directive wheel.
It is further characterized by, and positive stop is installed in described arm lower end;
Described fixture block sidepiece installs roller, described roller and described T-shaped draw-in groove contact internal walls.
After adopting the structure of the present invention, the piston rod of telescopic oil cylinder stretches out or shrinks, and the second directive wheel can be driven to move in T-shaped draw-in groove, it is not necessary to raises arm and can realize the lifting of different distance place material, simple in construction, process and assemble aspect.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram;
Fig. 2 is T-shaped draw-in groove and fixture block attachment structure schematic diagram in the present invention.
Detailed description of the invention
See Fig. 1, shown in Fig. 2, a kind of boom structure, it includes arm 1, hoister winch 2 is installed in arm 1 upper end, arm 1 head fixedly mounts the first directive wheel 3, removable guide wheel mounting seat 4 is installed in first directive wheel 3 lower end, directive wheel mounting seat 4 is installed the second directive wheel 5, T-shaped draw-in groove 6 is had bottom arm 1, directive wheel mounting seat 4 is installed the fixture block 7 coordinated with T-shaped draw-in groove 6, arm 1 lower end fixed installation telescopic oil cylinder 8, the piston rod of telescopic oil cylinder 8 connects directive wheel mounting seat 4, fixture block 7 card is embedded in T-shaped draw-in groove 6, lifting rope 9 one end is connected with hoister winch 2, the other end sequentially passes through the first directive wheel 3, connecting shackle 10 after second directive wheel 5, positive stop 11 is installed in arm 1 lower end, plays restriction directive wheel and installs the effect that 4 seats are put, fixture block 7 sidepiece installs roller 12, roller 12 and T-shaped draw-in groove 6 contact internal walls, and roller 12 plays the effect that auxiliary fixture block 7 moves, and leads for fixture block 7 simultaneously.
