Abstract
The utility model discloses a light mounting and dismounting frame for a tower crane. The frame comprises a rotatable main chord member, a reel device provided with an electromagnetic braking motor, a diagonal and an electric hoist group, wherein the lower end of the rotatable main chord member is perpendicularly inserted in a base, the middle of the rotatable main chord member is hinged to the lower end of the diagonal, a pulley is arranged at the upper end of the rotatable main chord member, the reel device is installed at the middle-lower part of the rotatable main chord member, a steel wire rope is arranged in the reel device, and one end of the steel wire rope winds around the pulley to be fastened in a lug plate hole in the top end of the diagonal through a steel wire rope clip; and the electric hoist group is installed on a lug plate at the top end of the diagonal. The light mounting and dismounting frame has the benefits as follows: the frame is rapid and convenient to mount, small in occupied space and convenient to transport; the rotatable main chord member can be rotated by 360 degrees, the diagonal can be used for arm changes of 15-85 degrees as required, and using requirements under different conditions can be met; and the mounting and dismounting frame can also be matched with a tower crane hoisting mechanism to mount and dismount balancing weights, so that the cost for hiring a crane is omitted, and the production efficiency is improved effectively.
Description
Technical field
The utility model relates to a kind of handling frame, and especially a kind of tower machine loads and unloads frame with hand-held design.
Background technology
At present, tower machine is as vertical transport instrument important in modern construction engineering, the increasing high buildings and large mansions of boosting are rised sheer from level ground, but because elevator machinery environment for use is severe and use frequent, easily cause wear and tear in machines et out of order, once machine et out of order just should be repaired immediately, bring loss in order to avoid delay the duration to client.And the maintenance of lifting mechanism after as its maintaining first of tower machine four great institutions and fault is applying unit problem the most deeply concerned always, because mechanism's reductor and motor are all larger parts, just likely need to disassemble maintenance or change once damage, so just need to employ crane, one to tear an expense that fills twice open be very considerable.Also having problem is that present tower crane uses brachium conversion very frequent, and counterbalanced weight on corresponding postbrachium also will change thereupon or tear open large packaged fritter or directly remove fritter, and it is not only expensive but also time-consuming that such variation all needs to employ crane.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, provides a kind of tower machine hand-held design to load and unload frame, it have quick and easy for installation, save space, the advantage such as can effectively enhance productivity.
For achieving the above object, the utility model adopts following technical proposals:
A kind of tower machine loads and unloads frame with hand-held design, comprise rotatable main chord, roll device, brace and electric block group with electromagnetic brake motor, the vertical base inserting with bearing seat and thrust ball bearing in described rotatable main chord lower end, rotatable main chord middle part is hinged with brace lower end, the upper end of rotatable main chord is provided with a pulley, described roll device is installed on the middle and lower part of rotatable main chord, in described roll device, be provided with steel rope, steel rope one end is walked around pulley and is fastened in the lug plate holes on brace top through wire rope grip; Described electric block group is installed on the otic placode on brace top.
Described rotatable main chord middle part is connected by bearing pin II with brace lower end.
Described roll device is installed on by tie bolt on the bearing of middle and lower part of rotatable main chord.
Described electric block group is installed on the otic placode on brace top by bearing pin I.
Brace and horizontal angle are 15 °～85 °.
The beneficial effects of the utility model are:
1 is quick and easy for installation, while use collapsible or disassemble place take up room little, convenient transportation;
2 rotatable mobile jibs are by manually can 360 ° of rotations, and brace can be made as required the change arm of 15 °～85 ° and use, and meets the operating needs of on-the-spot various different conditions, exempts client's trouble and worry;
3 handling framves also can coordinate Lift Mechanism in Power Hoist that counterweight block is dismantled and installed, and save the expense of employing crane, have effectively improved production efficiency.
