Abstract

Provided is an electric driven platform for tower crane inner frame lifting operation. Through traction of an electric block which is fixed on a lower rotational fulcrum bearing support of a tower crane, a primary steel wire rope penetrates downwards, rounds a steering pulley at the bottom of an inner frame and then goes straightly upwards to reach the top of the inner frame, the end of the primary steel wire rope is fixed at one end of a rope collecting device, the other end of the rope collecting device is fixedly connected with four secondary tractive steel wire ropes, then the four secondary tractive steel wire ropes pass four corresponding steering pulleys to respectively round a left rope distributing pulley and a right rope distributing pulley and go downwards, and the ends of the four secondary tractive steel wire ropes are finally connected with four corners of the operating platform in suspension mode. When the electric block runs, the main steel wire rope drives the four secondary tractive steel wire ropes to move so as to realize rising and descending of the operating platform, when the platform reaches to an operating height, operating staffs can enter into the platform for operation by overlapping jointing rods of four anti-falling devices onto horizontal web members of the inner frame through manual operation and inserting hinge pins into the anti-falling devices for locking.

Description

Stock jacking operation electric platforms in a kind of tower crane
Technical field
The utility model relates to stock jacking operation electric platforms in a kind of tower crane, belongs to building handling machinery field.
Background technology
The jacking of stock jacking job platform in the conventional tower crane, employing be under the oil cylinder effect together with interior stock and above all pivoting parts thereof move with flowing mode.This jacking mode is influenced by the work speed of jacking hydraulic efficiency pressure system and degree of safety, the fiduciary level of whole jacking hydraulic efficiency pressure system all, and kinematic velocity is slow, and safety reliability is not high, operates dumb.
The utility model content
The purpose of this utility model is at the deficiencies in the prior art, and a kind of energy flexible operating is provided, and does not rely on hydraulic jacking system and the higher electric block winding type electric platforms of the safety reliability of independently working.
The technical solution of the utility model is as follows:
Stock jacking operation electric platforms in a kind of tower crane, it is characterized in that described electric platforms is by electric block, main rope, deflection sheave, collection rope device, divide steel rope, divide the rope pulley frame, job platform, compositions such as anti-fall device, electric block is installed on the revolution lower supporting frame, wear by its main haulage cable and upwards to keep straight on after walking around the deflection sheave that is positioned at stock below, be anchored on the collection rope device in arriving after the cover top of the trellis again, tell four branch haulage cables by collection rope device, about walk around respectively two be installed in the double flute deflection sheavies at stock center, be divided into then wearing again after four tunnel 90 ° of spaces turn to and move into into pulley yoke, two parallel branch rope pulley framves are rigidly connected in the revolution lower supporting frame, and revolution lower supporting frame and interior stock are for being rigidly connected, four branch haulage cables are respectively from the two ends rope stretching of two pulley yokes, and suspention is anchored on four angles of job platform, after electric block drives job platform arrival operation height, be overlapped on respectively on the adjacent interior horizontal web member of stock by the bar of taking that manually will be arranged on job platform four anti-fall devices all around, insert the bearing pin locking in anti-fall device, the operating personnel can enter platform and implement operation.
Compare with cover jacking job platform in the existing similar tower machine, the beneficial effects of the utility model are:
1, by the traction technique of electric block, utilize to collect earlier the way suspention tower machine jacking job platform that afterwards divides, make it form a power platform lifting system that is independent of outside the jacking Hydraulic Station;
2, broken the trailing type of traditional dependence hydraulic lifting work from the way that rises job platform;
3, the job platform people that mustn't stand in motion process runs to and enables anti-fall device behind the job position and to prevent the driving system back of losing efficacy falling accident takes place, and the operating personnel enters platform work, guarantees safe and reliable;
4, implement the utility model after, job platform can be independently, effectively, flexibly, lifting freely, break away from the traditional method that the whole low speed of original dependence promotes;
5, applicable to cover jacking work operations flat-bed lifting field in the tower machine.
