Abstract
The utility model discloses a pole top lifter comprising a pull rod and a jacking rod, wherein the pull rod is movably connected with the top of a wire pole; the upper part of the jacking rod is movably connected to one side of pull rod, which is far away from the wire pole; the lower part of the jacking rod is movably connected with a cross arm arranged on the wire pole; a fixed pulley is arranged on the pull rod on the side far away from the wire pole; and a power mechanism is arranged in the middle of the jacking rod, and is connected with a rope with a hook through the fixed pulley arranged on the pull rod. A heavy object to be lifted is hung on the hook; the power mechanism arranged in the middle of the jacking rod is rotated to lift the hook of the rope through the fixed pulley; the heavy object is lifted with the hook; when the heavy object is lifted to a proper position, a one-way gear rotation component can stop very conveniently to conduct transversal displacement and other operations to the heavy object; and owing to the existence of the one-way gear rotation component, the heavy object can be prevented from falling effectively, so as to improve the safety in use. The pole top lifter has a simple structure, operates stably and is convenient for daily maintenance and management.
Description
Technical field
The utility model belongs to lifting weight simple machine technical field, particularly a kind of masthead lifter.
Background technology
When electric power transmission line or communication line construction; Often need transfer weight to line bar top; The construction workman promotes weight with the form of climbers climbing, has potential safety hazard on the one hand, on the other hand; The quality of transferring weight also receives very big restriction, can not satisfy the demand that promotes weight toward masthead.Construct after the workman gets on exactly in the aspect that another kind is used morely; Up promote weight through pulley; Need very long rope on the counterweight system this time, the wearing to send and need the construction workman go up lower beam repeatedly of fag end on the one hand is arranged near the masthead because of pulley on the other hand; With the close of circuit, safety misadventure appears easily.Also do not have at present a kind of instrument that line masthead portion promotes weight that is specifically designed to, the workman's better and safer of helping to construct promote the weight operation.
The utility model content
The utility model provide a kind of promote weight convenient, fast, effectively improve the masthead lifter of weight quality.
A kind of masthead lifter; Comprise the pull bar and the push rod that flexibly connect with line masthead portion; The top of said push rod and pull bar flexibly connect away from a side of line bar, and the bottom flexibly connects with the cross-arm that is provided with on the online bar, and said pull bar is provided with fixed pulley away from a side of line bar; Said push rod middle part is provided with actuating unit, and said actuating unit is connected with the rope of a band hook through the fixed pulley that is provided with on the pull bar.
Said actuating unit is the ratchet rotatable parts of band rocking arm.
Because the utility model comprises pull bar and the push rod that flexibly connects with line masthead portion, the top of said push rod and pull bar flexibly connect away from a side of line bar, and the bottom flexibly connects with the cross-arm that is provided with on the online bar; Said pull bar is provided with fixed pulley away from a side of line bar, and said push rod middle part is provided with actuating unit, and said actuating unit is connected with the rope of a band hook through the fixed pulley that is provided with on the pull bar; To promote weight in advance and hang on the hook, rotate the actuating unit that the push rod middle part is provided with, and drive the rope hook through fixed pulley and rise; Weight promotes thereupon, and when bringing up to correct position, the ratchet rotatable parts can stop easily; Weight is carried out operations such as cross travel; The existence of ratchet rotatable parts can also prevent the decline of weight effectively, has improved the safety of using.The mode that flexibly connects between push rod, pull bar, the cross-arm is convenient to safety and dismounting, has reduced running cost, has improved capacity utilization rate; The utility model is simple in structure, stable, is convenient to daily attention and management.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As shown in Figure 1: a kind of masthead lifter; Comprise and line bar 1 top movable bonded assembly pull bar 2 and push rod 5; The top of said push rod 5 and pull bar 2 flexibly connect away from a side of line bar 1, and the bottom flexibly connects with the cross-arm 4 that is provided with on the online bar 1, and said pull bar 2 is provided with fixed pulley 8 away from a side of line bar 1; Said push rod 5 middle parts are provided with actuating unit 6, and said actuating unit 6 is connected with the rope of a band hook 9 through the fixed pulley 8 that is provided with on the pull bar 2.Said pull bar 2 is connected with the mounting ring 3 of masthead through the attaching parts 7 between end.Said actuating unit 6 is ratchet rotatable parts of band rocking arm.Because the utility model will promote weight in advance and hang on the hook 9, rotate the actuating unit 6 that push rod 5 middle parts are provided with, drive rope hook 9 through fixed pulley 8 and rise; Weight promotes thereupon, and when bringing up to correct position, the ratchet rotatable parts can stop easily; Weight is carried out operations such as cross travel; The existence of ratchet rotatable parts can also prevent the decline of weight effectively, has improved the safety of using.The mode that flexibly connects between push rod 5, pull bar 2, the cross-arm 4 is convenient to safety and dismounting, has reduced running cost, has improved capacity utilization rate; The utility model is simple in structure, stable, is convenient to daily attention and management.
Claims (2)
1. masthead lifter; Comprise the pull bar and the push rod that flexibly connect with line masthead portion; It is characterized in that: the top of said push rod and pull bar flexibly connect away from a side of line bar, and the bottom flexibly connects with the cross-arm that is provided with on the online bar, and said pull bar is provided with fixed pulley away from a side of line bar; Said push rod middle part is provided with actuating unit, and said actuating unit is connected with the rope of a band hook through the fixed pulley that is provided with on the pull bar.
