Abstract
A slewing blackout control device of a tower crane comprises a housing, an impeller of a hydraulic coupler arranged in the housing, a gland, a bottom cover, a braking steel disk, a friction disk and amagnetic coil; the gland is fixedly connected with the braking steel disk; the braking steel disk is matched with the friction disk; the friction disk is fixedly connected with the braking steel disk; the gland is connected with the bottom cover by a back spring; the bottom cover is arranged in the housing; the lower end of a main shaft is provided with an output gear. The device further comprises an operating handle arranged in a cab, a compression ring and cam eccentric shafts; the operating handle is connected with a steel wire rope which is connected with the compression ring; two cam eccentric shafts are positioned at the two sides of the upper part of the gland; the bearing of the cam eccentric shafts is arranged in the housing; the two ends of the compression ring are fixedly connected with the cam eccentric shafts respectively; and a travel switch is arranged on the operating handle for controlling the power-on or power-off. The device of can manually control the stop after the blackout, avoid collision accident caused by the inertia, and has good safe performance.
Description
(1) technical field
The present invention relates to a kind of power loss control apparatus for tower crane rotation.
(2) background technology
At present the tower machine in the ordinary course of things the rotary braking system all be normal open form formula, in a single day the uncontrollable revolution of driver of promptly cutting off the power supply stops, when effect of inertia and influenced by wind pressure, cause suspension hook easily, hang thing and under the get out of hand situation, bump against dangerous objects such as operating personnel, building and high-tension cable, thereby cause than serious accident.
(3) summary of the invention
For uncontrollable after the outage that overcomes existing tower machine rotary braking system, as to have potential safety hazard deficiency, the invention provides and a kind ofly after outage, can manually control the generation that stops, effectively preventing to answer the bump accident that inertia causes, and the good power loss control apparatus for tower crane rotation of safety performance.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of power loss control apparatus for tower crane rotation, comprise casing, be installed in the fluid coupling impeller in the casing, gland, bottom, the braking steel disc, friction lining and magnet coil, described fluid coupling impeller is installed in the main shaft upper end, suit gland successively from top to bottom on the described main shaft, the braking steel disc, friction lining and magnet coil, described gland is captiveed joint with the braking steel disc, described braking steel disc cooperates with friction lining, described friction lining is captiveed joint with the braking steel disc, described gland is connected with bottom by retracing spring, described bottom is installed in the casing, output gear is installed in the lower end of described main shaft, described power loss control apparatus also comprises the operating handle that is installed in driver's cab, pressure ring, the cam eccentric shaft, described operating handle connects steel rope, described steel rope connects pressure ring, two cam eccentric shafts are positioned at the both sides of the top of gland, the bearing installation of described cam eccentric shaft is in casing, captiveing joint with the cam eccentric shaft respectively in the two ends of described pressure ring, installs on the described operating handle to be used to control the travel switch that power supply disconnects or connects.
Technical conceive of the present invention is: drive steel rope by operating handle, rope belt dynamic pressure ring rotates, and pressure ring drives with the cam eccentric shaft and rotates, and makes the cam eccentric shaft toward pressing down, and the braking steel disc contacts with friction lining, so just plays the rotary braking effect.
When the tower machine in normal working conditions, sudden power lost efficacy the revolution electric braking, the operating handle of control setup is installed in the driver's cab, the driver has information such as enough time response tower machines have cut off the power supply, in time operating handle stops revolution.Under the situation that electricity is arranged, the tower machine cuts off the power supply automatically under the operating handle effect, prevents that effectively the maloperation situation from producing.
Beneficial effect of the present invention mainly shows: can manually control the generation that stops, effectively preventing to answer the bump accident that inertia causes after outage, and safety performance is good.
