Abstract
The utility model proposes a kind of double horizontal arm tower crane and receive arm mechanism, including the tower top structural member being fixed on above slewing tower and the horizontally hinged jib in tower top structural member root both sides, also include two winding plants being arranged on below tower top structural member.Two groups of fixed pulleys are fixed at the top of tower top structural member.Both sides jib winds up and is respectively equipped with movable pulley, and steel wire rope is drawn from winding plant, passes sequentially through fixed pulley and movable pulley, and termination is fixed on jib or tower top structural member.This utility model is by arranging independent receipts arm mechanism, complete the receipts arm work of double horizontal arm tower crane, it is to avoid again pass around steel wire rope operation during receipts arm, be conducive to improving work efficiency, promote the safety of disassembly process, there is substantive distinguishing features and progress.
Description
Technical field
This utility model relates to power transmission tower frame technical field of construction, is specifically related to a kind of double horizontal arm tower crane and receives arm
Mechanism.
Background technology
Part specific use derrick crane such as power transmission tower installation double horizontal arm tower crane, needs in demolishing process
Jib reclaimed and to be brought to tower top.In prior art, the receipts arm mechanism of double horizontal arm tower crane is performing receipts arm operation
Time, need again to pass around hoisting mechanism steel wire rope, utilize lifting mechanism to complete to receive arm as power.Again steel wire rope is passed around
Work, needs manually to complete in high-altitude, and one carrys out workload relatively greatly, and two exist potential safety hazard.
Utility model content
The utility model proposes a kind of double horizontal arm tower crane and receive arm mechanism, solve double horizontal arm tower in prior art
Formula crane, when performing to receive arm operation, needs the technical problem manually again passed around by hoisting mechanism steel wire rope in high-altitude.
The technical solution of the utility model is achieved in that a kind of double horizontal arm tower crane receives arm mechanism, including
It is fixed on the tower top structural member above slewing tower and is hinged on the jib of tower top structural member root both sides, also including being arranged on tower
Two winding plants below roof construction part.Two groups of fixed pulleys are fixed at the top of tower top structural member, and both sides jib winds up and sets respectively
Having movable pulley, steel wire rope is drawn from winding plant, passes sequentially through fixed pulley and movable pulley, and termination can be fixed on arm as required
On frame or tower top structural member, form many multiplying powers assembly pulley and receive arm mechanism.When derrick crane work jib is in level,
Operation controls winding plant makes steel wire rope loosen, and does not affect jib and other structures, mechanism's work；When needing to pack up jib, behaviour
Make winding plant rolling steel wire rope, make jib rotate near tower top around root hinge.
The both sides of described tower top structural member are provided with the connection seat of fixing jib, and described jib correspondence position is provided with described
Connecting the otic placode that seat matches, described otic placode is fixed with the described seat that is connected by bearing pin.When receiving arm, when jib revolves around root hinge
Turn near tower top rear stop in place, with bearing pin, otic placode is fixed with being connected seat, it is ensured that safety.
This utility model is not against the lifting mechanism of derrick crane, by arranging independent receipts arm mechanism, completes double water
The receipts arm work of flat arm derrick crane, it is to avoid again pass around steel wire rope operation during receipts arm, is conducive to improving work effect
Rate, promotes the safety of disassembly process, has substantive distinguishing features and progress.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment, the required accompanying drawing used in embodiment being described below
It is briefly described, it should be apparent that, the accompanying drawing in describing below is only embodiments more of the present utility model, for ability
From the point of view of the those of ordinary skill of territory, on the premise of not paying creative work, it is also possible to obtain the attached of other according to these accompanying drawings
Figure.
Fig. 1 is that this utility model one double horizontal arm tower crane receives arm mechanism schematic diagram.
Labelling in figure, 1, fixed pulley；2, steel wire rope；3, seat is connected；4, tower top structural member；5, winding plant；6, movable pulley；
7, end fixing device；8, jib；9, jib winds up；10, slewing tower；11, otic placode.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Being that a kind of double horizontal arm tower crane receives arm mechanism shown in figure, tower top structural member 4 is hingedly fixed in turret
The top of body 10, jib 8 is hinged on the both sides of tower top structural member 4 root, in the lower section of tower top structural member 4, arranges two elevators
Device 5, the top of tower top structural member 4 fixes two groups of fixed pulleys 1, and the jib of both sides winds up and is respectively equipped with end fixing device 7 on 9
With one group of movable pulley 6, steel wire rope 2 is drawn from winding plant 5 respectively, is passed sequentially through fixed pulley group 1 and movable pulley 6, according to again
Rate needs to be fixed on end fixing device 7 or on tower top structural member 4 after fixed pulley group 1 returns, and forms many multiplying powers assembly pulley
Receive arm mechanism.
The both sides of tower top structural member 4 are provided with the connection seat 3 of fixing jib 8, and the correspondence position of jib 8 is provided with and is connected seat
The otic placode 11 of 3 couplings, is connected and can be fixed by pivot pin between seat 3 and otic placode 11.
When jib 8 is in level, operation control winding plant 5 makes steel wire rope 2 loosen, do not affect jib 8 and
His structure, mechanism's work；When needing to pack up jib 8, operate winding plant 5 rolling steel wire rope 2, make jib 8 revolve around root hinge
Turn near tower top structural member 4, rear stop in place, with bearing pin, connection seat 3 is fixed with otic placode 11, complete one and receive arm work.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all at this
Within the spirit of utility model and principle, any modification, equivalent substitution and improvement etc. made, should be included in this utility model
Protection domain within.
