Description
Technical field
The utility model relates to a kind of insulation single direction rotation tackle block, and especially transmission line of electricity hotline maintenance operation tackle block, belongs to power transmission lines overhauling equipment technical field.
Background technology
In the operation of transmission line of electricity hotline maintenance, exist a lot of lifting works, especially use tackle block to tool for transmitting, material etc. on shaft tower, these work complete by manpower mostly, when tool material is heavier, needs many people pull and transmit rope.After weight lifting, when personnel are firmly slightly smaller than the weight of weight or slide due to tired hand, transmitting rope will fall after rise along tackle block, wasted and pulled the muscle power of transmitting rope personnel, as controlled not in time, may cause weight to fall after rise very fast, injure the personal safety of staff under tower, also extended the time of service work, reduced work efficiency simultaneously.
Utility model content
The utility model object is to provide a kind of insulation single direction rotation tackle block, prevents from falling after rise after weight lifting, solves the problem existing in background technology.
The technical solution of the utility model is:
A kind of insulation single direction rotation tackle block, comprise hook, safe hyoplastron, insulation protective board, hook base, insulating block and guide bearing, hook is fixed on hook base, hook opening part is provided with safe hyoplastron, two insulation protective board upper ends that are parallel to each other are bolted to by opening the door on hook base, lower end is provided with guide bearing, and guide bearing is provided with bearing draw-in groove and pulley draw-in groove, and insulating block is arranged on guide bearing.
Between described insulating block and insulation protective board, be provided with insulation barrier.
Described insulation protective board, insulating block and insulation barrier are epoxide resin material.
Adopt the utility model, nylon buckles is put in hook, open the bolt that opens the door, transmissions restricted and put in insulating block, close the bolt that opens the door, prevent that insulation barrier from opening automatically.Staff hangs over hook on shaft tower angle steel with nylon buckles, under tower, staff is with transmitting one end colligation weight of restricting, pull other end transmission rope, because insulating block can only can not retrograde rotation to transmitting weight direction rotation, when the staff of pulling transmission rope changes hands or pauses, transmit rope and can effectively prevent that with the friction force of insulating block weight from falling after rise downwards, weight is delivered on tower smoothly.
The beneficial effects of the utility model are: simple in structure, easy to use, time saving and energy saving, increase work efficiency, and reduce labor strength, guaranteed the safety of service work.
Accompanying drawing explanation
Fig. 1 is the utility model front view;
Fig. 2 is the utility model lateral plan;
Fig. 3 is the utility model cutaway view;
Fig. 4 is the utility model guide bearing cutaway view;
In figure: hook 1, safe hyoplastron 2, bolt of rear end plate 3, insulation protective board 4, punching bolt 5, insulation barrier 6, hook base 7, the bolt 8 that opens the door, insulating block 9, guide bearing 10, pulley draw-in groove 11, bearing draw-in groove 12.
The specific embodiment
Below in conjunction with accompanying drawing, by example, the utility model is described in further detail.
With reference to accompanying drawing 1, 2, 3, 4, a kind of insulation single direction rotation tackle block, comprise hook 1, safe hyoplastron 2, insulation protective board 4, hook base 7, insulating block 9 and guide bearing 10, insulation protective board 4, insulating block 9 and insulation barrier 6 adopt epoxide resin material, other is metallic material, hook 1 is fixed on hook base 7, link up with 1 opening part and be provided with safe hyoplastron 2, safe hyoplastron 2 inside are provided with hyoplastron spring, play reset role, two insulation protective board being parallel to each other 4 upper ends are fixed on hook base 7 by the bolt 8 that opens the door, lower end is provided with guide bearing 10, guide bearing 10 is fixed on insulation protective board 4 bottoms by punching bolt 5, guide bearing 10 is provided with bearing draw-in groove 12 and pulley draw-in groove 11, insulating block 9 is arranged on guide bearing 10, between insulating block 9 and insulation protective board 4, be provided with insulation barrier 6, during lifting heavy, insulating block 9 can not retrograde rotation.
During use, with safe hyoplastron 2 under hand, nylon buckles is put in hook 1, under the effect of portion's hyoplastron spring within it of safe hyoplastron 2, make it get back to original position, open the bolt 8 that opens the door, transmission rope is put in insulating block 9, close the bolt 8 that opens the door, prevent that insulation barrier 4 from opening automatically.Staff hangs over hook 1 on shaft tower angle steel with nylon buckles, under tower, staff is with transmitting one end colligation weight of restricting, pull other end transmission rope, because insulating block 9 can only can not retrograde rotation to transmitting weight direction rotation, when the staff of pulling transmission rope changes hands or pauses, transmit rope and can effectively prevent that with the friction force of insulating block 9 weight from falling after rise downwards, weight is delivered on tower smoothly, not only alleviated staff's labour intensity, reduce production time, and guaranteed the safety of service work.
