Description
Technical field
The present invention relates to power construction utensil, particularly in the stringing of large span distribution line, vertical rod construction, play the swaying type wire grip of cable tensioning function by steel wire tail rope.
Background technology
Existing hand operated wring grinder structurally has the main mill heart of a coiling and a set of shaking gear transmission mechanism, and the brake mechanism of main mill heart employing hood type structure, is similar to the brake structure of existing electric bicycle.In practice of construction, owing to only having a main mill heart, cause the pulling force of tail rope large, strand mill tail rope operating personnel's danger coefficient is high, brings hidden danger to safety in production.
Summary of the invention
The object of this invention is to provide and a kind ofly can firmly control steel wire tail rope, safe distribution line construction equipment and have the hand operated wring grinder of tail rope buffer-braking function.
The object of the present invention is achieved like this: a kind of distribution line construction equipment has the hand operated wring grinder of tail rope buffer-braking function, comprise the hand operated wring grinder being arranged on bracing frame, tail rope buffer-braking mechanism is also installed: be fixed on axle as time mill heart that is wound around tail rope on the bracing frame of described hand operated wring grinder below, axle is installed in rotation on bracing frame, in the inferior mill heart one side, integrated setting has ratchet, is arranged on bracing frame with the ratchet of ratchet mating reaction.
Above-mentioned hand operated wring grinder structure is: driving shaft and driven shaft respectively along continuous straight runs are installed in rotation on bracing frame, a driving shaft left side, right side is separately installed with the first hand driving gear and the second hand driving gear, a driven shaft left side, right both sides are separately installed with the first driven gear and the second driven gear, the first hand driving gear and the first driven gear engaged transmission, the second hand driving gear and the second driven gear engaged transmission, and the first hand driving gear is identical with the second driven gear, the second hand driving gear is identical with the first driven gear, the gear ratio of the first hand driving gear and the first driven gear is 3: 1, the main mill heart is fixed on driving shaft, and in the main mill heart one side, integrated setting has main ratchet, is arranged on bracing frame with the main ratchet of main ratchet mating reaction.
The above-mentioned main mill heart and time mill heart are the column with indent curved surfaces.
Operating personnel is by steel wire rope after the main mill heart is wound around, and steel wire tail rope draws to the inferior mill of buffer-braking mechanism and is wound around in the heart two circles, and controls steel wire rope tail rope by special messenger.Its Main Function is the operating personnel who prevents from controlling steel wire rope, because a variety of causes causes the control of steel wire tail rope insecure, now the click brake apparatus in buffer-braking mechanism will play secondary braking effect, avoid impacting operating personnel and equipment being damaged suddenly.
The present invention disperses the pulling force of tail rope to bear, and the pulling force of tail rope is diminished, and easy operating control reduces associative operation personnel's security risk, effectively enhances productivity.Time mill heart of main mill heart below is shared the power that original power transmission shaft is born, and then reduces operating personnel's tensile load.
The beneficial effect of this device is: this equipment safety is high, and the main mill heart and time mill heart all adopt click brake mechanism, have brake operating convenient, brake feature fast and effectively.At the bottom of cost, practical, flexible operation (increased a set of shaking gear transmission mechanism on existing hand operated wring grinder, wherein a sets of transmission mechanism is for take-up, and another set of transmission mechanism uses for unwrapping wire).Time saving and energy saving, improve line construction efficiency, can overcome preferably the potential risk in the use procedure of hand operated wring grinder tail rope, can well meet construction requirement defeated, distribution line, possess larger production, popularization and practical value.
