Abstract

The utility model provides a swing arm tower crane assists hoist mechanism, including fixing supporting platform and the hoisting accessory on the body of the tower respectively, still include hoist engine and rope guide device, the hoist engine is installed supporting platform is last, and passes through rope guide device with hoisting accessory connects. The utility model discloses combine the hoist engine effectively to be in the same place with swing arm tower crane, realized the hoist and mount to object in the blind area around the swing arm tower crane body of the tower, simple structure, the operation is nimble, has practiced thrift manufacturing cost, has improved production efficiency, has substantive characteristics and progress.

Description

A kind of arm tower crane auxiliary lifting mechanism
Technical field
The utility model relates to construction machine field, particularly a kind of arm tower crane auxiliary lifting mechanism.
Background technology
In recent years, along with the development of construction trade, arm tower crane application is more and more extensive.According to its structure and operating feature, around arm tower crane self, usually have the lifting blind area (brachium is the arm tower crane of 50m, and its blindarearadius is generally at about 5m) of certain radius.For solving arm tower crane self lifting blind zone problem, simultaneously conventional method arranges two arm tower cranes, cooperatively interacts, carry out tower body peripheral parts service hoisting.Adopt in this way, need to take two arm tower cranes simultaneously and complete a lifting task, construction cost is large, inefficiency, if run into arm tower crane in building structure in climb or coordinate with full automaticity mould bases climbing system time, due to place restriction, construction operation can be made to become very difficult.
Utility model content
The utility model proposes a kind of arm tower crane auxiliary lifting apparatus, solve arm tower crane self lifting blind area shop problem in prior art.
The technical solution of the utility model is achieved in that a kind of arm tower crane auxiliary lifting mechanism, comprise and be separately fixed at support platform on tower body and lifting appliance, also comprise winch and wire line guide, described winch is arranged in described support platform, and is connected with described lifting appliance by described wire line guide.
Described lifting appliance comprises the hold-down arm be fixed on tower body, be arranged on described hold-down arm and the ceiling mounted arm that can stretch vertically be arranged on described ceiling mounted arm end and the lifting pulley be connected with suspension hook.
Described ceiling mounted arm adopts sleeve structure, and one end is connected with described hold-down arm by rotating shaft, and the other end is fixed by fastening device for positioning and described hold-down arm.Realize the flexible of ceiling mounted arm by sleeve structure, change the length of ceiling mounted arm, meet different lifting demands.
Described wire line guide comprises the guide frame being fixed on tower body inside and the leading sheave be fixed on described guide frame.Steel rope guide frame is installed to tower body inside, utilizes steel rope guide frame, make steel rope connect winch and suspension hook by tower body inside, reach lifting function.
Winch and arm tower crane combine by the utility model effectively, and achieve the lifting of object in blind area around arm tower crane tower body, structure is simple, operating flexibility, save productive costs, improve production efficiency, there is substantive distinguishing features and progress.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
In figure, support platform 2 is fixed on tower body 1, and winch 3 is fixed in support platform 2.Lifting appliance 4 is fixed by hold-down arm 6 and tower body 1, and ceiling mounted arm 7 one end is connected with hold-down arm 6 by rotating shaft 10, and the other end is fixed by fastening device for positioning 11 and hold-down arm 6.Ceiling mounted arm 7 adopts sleeve structure, can stretch along axis, and to adapt to the weight lifting by crane diverse location, lifting pulley 8 is installed on the working end of ceiling mounted arm 7.Wire line guide 5 is installed on the inside of tower body 1 by guide frame 12, and guide frame 12 is provided with leading sheave 13, and the steel rope 14 of winch 3 walks around leading sheave 13 and lifting pulley 8, is connected, for hoisting heavy with suspension hook 9.
The utility model is applicable to arm tower crane, by the local flow improvement to winch, climbs in can adapting to, outer attached, the plug-in and all kinds of coordinating operation ability from climbing shuttering form frame system, and structure is simple, and applying flexible is extensive.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
