Description
Technical field
The invention belongs to the realm of building construction, especially a kind of simple crane.
Background technology
Traditional crane in the building field of building site is broadly divided into whether there is or not the simple crane of clump weight and has matching for clump weight
Weight crane.Common counterweight crane is that concrete is arranged on rear side of pedestal（Or bloom）Clump weight, it is mobile difficult from great, take
When take a lot of work, once it is fixed be difficult to be moved.And general simple crane is all the angle that arm or more is adjusted by steel wire rope
And the swing of horizontal direction, the arm of long range can not be set and heavy weight article can not be sling.The two cranes exist
In actual use all have limitation, therefore building field be badly in need of it is a kind of have the advantages that the two and without the crane of the two disadvantage.
Invention content
The present invention is directed to deficiency in the prior art, provides a kind of no counterweight crane, this crane can be by strut upper
Sub-floor plates are held out against, tilting moment when balancing lifting, and length of boom can freely stretch, and can up and down, left-right rotation,
It is big to lift by crane range.Also have many advantages, such as the small, hoisting weight of dead weight it is big, it is mobile flexibly, it is in place convenient, solve existing building with matching
The problems of weight crane and simple crane.
In order to solve the above-mentioned technical problem, the present invention is addressed by following technical proposals：A kind of no counterweight crane, packet
Frame body is included, rolling bearing is provided on the frame body, mobile platform is provided on the rolling bearing, the movement is flat
Telescopic arm is provided on platform, be additionally provided on the mobile platform with the matched hoist engine of the arm, it is described
Frame body on be additionally provided with several and can resist the vertical strut of floor plates, the vertical strut is in the mobile platform
Dead astern.
In above-mentioned technical proposal, it is preferred that be additionally provided with jack, jack connection on the rolling bearing
There is the arm.
In above-mentioned technical proposal, it is preferred that the arm includes adjustable arm and fixed arm, the adjustable arm
It can move and fix on the fixation arm, the jack connection fixation arm.
In above-mentioned technical proposal, it is preferred that the vertical strut includes fixed strut and rod-adjurstable, and described is adjustable
Strut can move up dynamic and fixed, described rod-adjurstable top in the fixation strut and be provided with spike.
In above-mentioned technical proposal, it is preferred that the frame body bottom is evenly arranged with several universal wheels.
In above-mentioned technical proposal, it is preferred that the frame body bottom is evenly arranged with several adjustable lower spikes, described
Lower spike can be fixed on the frame body and dropping distance can allow the universal wheel hanging.
In above-mentioned technical proposal, it is preferred that the adjustable arm and the fixation arm are bolted.
In above-mentioned technical proposal, it is preferred that the fixation strut and rod-adjurstable are bolted.
In above-mentioned technical proposal, it is preferred that be bolted between the lower spike and the frame body.
The present invention be a kind of arm can three-dimensional regulation without counterweight simple crane, the arm of this crane is multi-section retractable structure
It makes, can freely adjust lifting range；Hydraulic jack is set under arm, the inclination angle of arm can be adjusted, is convenient for sling height
Larger article；Rotary bearing is arranged in arm root so that arm can horizontally rotate, and be convenient for the transhipment of article.
4 universal wheels are arranged in frame body lower part, are moved convenient for crane, and 4 lower spikes on universal wheel side are fallen after in place can allow crane
It is fixed.On rear side of frame body setting can adjustable orthogonal strut up and down, orthogonal strut can be allowed to be held out against with upper sub-floor plates, using vertical
The tilting moment of the pressure balance crane of straight strut and floor.
Compared with prior art, this crane can be held out against by strut in upper sub-floor plates, tilting moment when balancing lifting,
And length of boom can freely stretch, and energy is upper and lower, left-right rotation, and lifting range is big.Also there is small, hoisting weight of conducting oneself with dignity
Greatly, mobile flexible, in place the advantages that facilitating, the problems of existing building counterweight crane and simple crane are solved.
Description of the drawings
Fig. 1 is schematic diagram of the present invention.
Fig. 2 is stereoscopic schematic diagram of the present invention.
Specific implementation mode
Present invention is further described in detail with specific implementation mode below in conjunction with the accompanying drawings.
Embodiment one：As shown in Figure 1 to Figure 2, a kind of no counterweight crane, including frame body 1 are provided on the frame body 1
