Description

Exempt to have enough to meet the need lifting appliance

Technical field

The utility model relates to the field of climbing frame lifting appliance, relates in particular to a kind of lifting appliance of exempting to have enough to meet the need.

Background technology

At present, attachment type raise scaffold is called for short climbing frame, and it promotes power and is generally electric block, and the mounting means of electric block mainly is divided into two kinds, just extension type and reversal of the natural order of things type.The electric block of these two kinds of hoisting way is Shortcomings parts all in use.Wherein, just extension type electric block needs manually going to next layer electric block week after finishing lifting at every turn, but the weight of electric block is generally about 100kg, artificial turnover is very inconvenient, and not only labour intensity is large, also easily causes to pound and hurts sb.'s feelings or the damage problem of elevator self.Although reversal of the natural order of things type electric block need not manually have enough to meet the need, easily lax near the chain of electric block one end under Action of Gravity Field owing to himself design feature, thus also just easily cause chain jamming in the lifting process.Simultaneously, the chain that bites also happens occasionally, and has potential safety hazard, has also shortened the application life of electric block simultaneously.In addition, reversal of the natural order of things type electric block is that choosing is blamed outside the scaffold support body, and in building construction process, the foreign material such as concrete easily enter the chain line shaft, and contamination resistance is poor, also can cause chain jamming.

Summary of the invention

The purpose of the utility model embodiment is: a kind of lifting appliance of exempting to have enough to meet the need is provided, need not turnover in the use procedure, thereby saved manpower, also accelerated operating efficiency, be difficult for simultaneously chain jamming, also just prolonged application life.

The utility model embodiment provides a kind ofly exempts to have enough to meet the need lifting appliance, comprises scaffold support body, elevator, spandrel girder, hook, pulley, guide rail, wire rope and lifting hanging seat; Described spandrel girder is bolted on described scaffold support body, and comprises spandrel girder and lower spandrel girder; Described elevator hangs on the described upper spandrel girder; Described hook is by the bottom of chain suspension in described elevator; Described wire rope one end is hung on described hook, and mid portion passes described pulley, and the other end is fixed on the described lifting hanging seat; Described pulley and described guide rail all are fixed in respectively on the described scaffold support body.

Optionally, also comprise the guiding relief arrangement.

Optionally, an end of described guiding relief arrangement and lifting hanging seat are bolted on building wall respectively.

Optionally, the other end of described guiding relief arrangement is stuck in the two side of described guide rail.

Optionally, described elevator is positioned at described scaffold support body.

Therefore, use the technical scheme of the utility model embodiment, by described elevator being hung on the described upper spandrel girder, then hang up hook in its bottom by chain, described hook tangles an end of described wire rope again, the described pulley of described steel wire penetrating then, and end is hung on the described lifting hanging seat, simultaneously, described lifting hanging seat is fixed on the described building wall.Exempt to have enough to meet the need lifting appliance in the process of hoisting scaffold support body described, described elevator brings into operation, by chain pulling hook, described hook spurs described wire rope, drive described pulley and rotate, thereby so that the overall length of described wire rope and chain shortens, force directive wheel to move upward with respect to building structure, directive wheel is bolted on support body, and is final so that scaffold support body Integral lifting.Need not to have enough to meet the need elevator in this process, can not relaxing and chain jamming because of chain yet.

Description of drawings

Accompanying drawing described herein is used to provide further understanding of the present utility model, consists of the application's a part, does not consist of to improper restriction of the present utility model, in the accompanying drawings:

A kind of structural representation of exempting to have enough to meet the need before the lifting appliance lifting frame body that Fig. 1 provides for the utility model embodiment 1;

A kind of structural representation of exempting to have enough to meet the need behind the lifting appliance lifting frame body that Fig. 2 provides for the utility model embodiment 1;

A kind of structural representation of exempting to have enough to meet the need in the lifting appliance guiding relief arrangement and guide rail that Fig. 3 provides for the utility model embodiment 1.

The specific embodiment

Describe the utility model in detail below in conjunction with accompanying drawing and specific embodiment, be used for explaining the utility model in this illustrative examples of the present utility model and explanation, but not as to restriction of the present utility model.

Embodiment 1:

As depicted in figs. 1 and 2, described in the utility modelly exempt to have enough to meet the need lifting appliance, comprise scaffold support body 1, elevator 2, spandrel girder, hook 4, pulley 5, guide rail 6, wire rope 7 and promote hanging seat 8; Wherein, described spandrel girder is bolted on described scaffold support body 1, and comprises spandrel girder 31 and lower spandrel girder 32; Described elevator 2 hangs on the described upper spandrel girder 31, and the power of lifting is provided, and described hook 4 hangs on the bottom of described elevator 2 by chain 9; Described wire rope 7 one ends are hung on described hook 4, mid portion passes described pulley 5, play guide effect for described wire rope 7, the other end is fixed on the described lifting hanging seat 8 that is positioned at last layer building wall 11, is fixed on the building wall 11 on the described lifting hanging seat 8; Described pulley 5 and described guide rail 6 all are fixed in respectively on the described scaffold support body 1.In the process that promotes, described elevator 2 is positioned at described scaffold support body 1, has avoided the extraneous foreign material such as concrete to enter chain 9, has also just avoided the appearance of chain jamming problem.

At first open described elevator 2, the described hook 4 of described chain 9 pullings of 2 mistakes of described elevator, then described hook 4 spurs again described wire rope 7, driving described pulley 5 rotates, thereby so that described pulley 5 rises with respect to described building structure, final so that described scaffold support body 1 Integral lifting.

As shown in Figure 3, for improvement of the technical scheme, describedly exempt to have enough to meet the need lifting appliance, also comprise guiding relief arrangement 10.Described guiding relief arrangement 10 1 ends are bolted in building wall 11, and the other end of described guiding relief arrangement 10 is stuck in the two side of described guide rail 6.Described wire rope 7 one ends hang on the described hook 4, then pass described pulley 5 after, finally be connected on the described lifting hanging seat 8.Thereby the function of the direction that described guiding relief arrangement 10 assurances are risen and overturn-preventing, fall arrest.Simultaneously, at scaffold support body 1 a plurality of described guiding relief arrangements 10 are installed, after whole described scaffold support body 1 promotes, need going to described 10 weeks of guiding relief arrangement topmost least significant end.Because for guiding relief arrangement 10, lightweight, volume is little, easily turnover.

The above technical scheme that the utility model embodiment is provided is described in detail, used specific case herein principle and the embodiment of the utility model embodiment are set forth, the explanation of above embodiment is only applicable to help to understand the principle of the utility model embodiment; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment, all will change on the specific embodiment and range of application, in sum, this description should not be construed as restriction of the present utility model.
