Abstract
The utility model discloses a kind of liftable portal frame, comprise the support of crossbeam and crossbeam both sides, every side stand includes fixed muffle and is socketed in the lifting frame body in fixed muffle, fixed muffle is equipped with support fixed pulley at top, steel rope rotating disk is equipped with below support fixed pulley, lifting frame body is equipped with lifting movable pulley in bottom, steel rope one end is fixed on after fixed muffle top also walks around described lifting movable pulley downwards and is wrapped on steel rope rotating disk through described support fixed pulley again, and described crossbeam two ends are connected with lifting frame body top, described both sides.The form that this portal frame two side stand adopts fixed muffle to combine with lifting frame body makes lifting frame body can move freely in fixed muffle, makes whole portal frame height adjustable.Both conveniently met various lifting needs, space shared by all right reduced volume, is convenient to transport.
Description
Technical field
The utility model relates to a kind of lifting appliance, in particular to a kind of liftable portal frame.
Background technology
The needs that portal frame is haulage equipment in basis, in the daily production of semiworks, warehouse passes in and out goods and lifting maintenance heavy wares and transport of materials, the small-sized lifting support platform developed.It is widely used in the occasion that die making shop, Automobile Service factory, mine, civil engineering building site etc. need lifting.The portal frame height of current use is fixed, and according to the incompatible adjustment height of concrete spatial field, can not bring some inconvenience to use, and due to highly non-adjustable, makes to take up room in transportation comparatively large, make troubles also to the transport of portal frame.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of liftable portal frame, and this device can adjust height according to actual needs, meets the lifting demand of multiple occasion.
In order to solve the problems of the technologies described above, the utility model takes following technical scheme:
A kind of liftable portal frame, comprise the support of crossbeam and crossbeam both sides, it is characterized in that, every side stand includes fixed muffle and is socketed in the lifting frame body in fixed muffle, fixed muffle is equipped with support fixed pulley at top, steel rope rotating disk is equipped with below support fixed pulley, lifting frame body is equipped with lifting movable pulley in bottom, steel rope one end is fixed on after fixed muffle top also walks around described lifting movable pulley downwards and is wrapped on steel rope rotating disk through described support fixed pulley again, and described crossbeam two ends are connected with lifting frame body top, described both sides.
Described lifting movable pulley is two, is disposed side by side on the bottom of described lifting frame body.
Be equipped with base bottom described fixed muffle, between fixed muffle and base, be connected with oblique stirrup.
Roller is equipped with below described base.
Described roller is equipped with brake gear.
The beneficial effects of the utility model are, owing to establishing on a steel cord through lifting movable pulley rack bottom lifting frame body, and steel rope is wrapped on steel rope rotating disk through supporting fixed pulley, therefore rotate steel rope rotating disk and namely can promote or discharge decline lifting frame body, both sides operate simultaneously, can smoothly crossbeam be promoted or be discharged to decline, thus play the adjustable effect of beam height, with the lifting requirement of satisfied different occasion, also effectively can reduce the volume of portal frame in addition and taken up space, being convenient to transport.
Accompanying drawing explanation
The main TV structure schematic diagram of Fig. 1 the utility model;
The left TV structure schematic diagram of Fig. 2 the utility model.
Detailed description of the invention
As shown in Figure 1 and Figure 2, support 1 is connected through crossbeam 3 with support 2, forms liftable portal frame.Support 1 is identical with support 2 structure, is described for support 1.Support 1 comprises the lifting frame body 5 of fixed muffle 4 and Qi Nei, fixed muffle 4 cross section can be rectangle or other shapes, fixed muffle is connected in lifting frame body 5, general is also rectangle or other shapes accordingly, one or two lifting movable pulley is equipped with bottom lifting frame body 5, in this example be two, be namely elevated movable pulley 6 and lifting movable pulley 7.Be equipped with in the top outer of fixed muffle 4 and support movable pulley 7, the below supporting movable pulley 7 is steel rope rotating disk 8, and steel rope rotating disk 8 is arranged on the downside of fixed muffle 4 through rotary base 9.One end of steel rope 10 is fixed on side, top 11 place of fixed muffle 4, walk around downwards lifting movable pulley 6,7 backward on pass through fixed muffle 4 top opposite side and walk around and support fixed pulley 12 and be wrapped in downwards again on steel rope rotating disk 8, rotate steel rope rotating disk and can tighten up or loosen steel rope 10, thus movable support body 5 can be made to rise or decline.The two ends of crossbeam 3 are all connected on two lifting frame bodies, and steel rope rotating disk is rotated in both sides simultaneously, finally can control crossbeam 3 and rise or decline.Crossbeam 3 can arrange lifting apparatus, thus finally complete startup work.The top of lifting frame body 5 is fixedly connected with crossbeam 3.
Can make bottom fixed muffle 4 and on the spot support alone, also can in order to improve the firmness and be arranged in respective seat 13 of landing, can to the oblique connection reinforcement bar 14 of base 13 and stirrup 15 in the both sides of fixed muffle 4, to strengthen firmness.Can arrange roller 16 below base 13, this makes portal frame entirety so that mobile, roller 16 can set up brake gear, prevent roller from producing less desirable rotation.
More than just illustrate one of the utility model design and unrestricted, under the utility model design, any technical scheme without essence conversion is all in this patent protection domain.
