Abstract
The utility model discloses a flexible arm -type cantilever crane, including the stand, set up in the stand upside and can for the stand is followed horizontal direction pivoted revoliving arm and is used for hoisting the electric block of article, wherein, the revoliving arm extending arm of wearing the cover in proper order by the multisection constitute, be provided with sharp driver part between two sections adjacent extending arms with the withdrawal that realizes two sections extending arms or stretch out, the fixed outer end that sets up at the revoliving arm of electric block. Adopting the shell type with the extending arm, effectively guaranteeing holistic atress, simplified the exterior structure simultaneously, set up the electric block snap -on moreover, the relative pathway movement who has simplified electric block sets up, and the whole processing cost of effective control through the axial removal of sharp driver part drive extending arm, effectively constitutes on the space and avoids, has improved its application range.
Description
Technical field
This utility model relates to technical field of crane equipment, particularly relates to a kind of telescopic boom cantilever crane.
Background technology
Cantilever crane, also known as cantilever crane, has the advantages such as easy for operation, revolution is flexible, working space is big, is the material lifting device of efficient energy-saving.Because cantilever crane hangs, small article is more convenient, power saving, is widely used in factories and miness, the production line in workshop, assembly line and the occasion such as the lifting workpiece of lathe and warehouse.Existing cantilever crane length is unadjustable, if any interferences in the radius of gyration, then limits the range of cantilever crane, it is impossible to meet the use demand of more people.
Utility model content
The purpose of this utility model is for technological deficiency present in prior art, and provides a kind of telescopic boom cantilever crane.
Be the technical scheme is that by realizing the purpose of this utility model
A kind of telescopic boom cantilever crane, including column, it is arranged on the upside of described column and the revoliving arm that can rotate in the horizontal direction relative to described column and the electric block for article hoisting, wherein, the extending arm that described revoliving arm is worn successively by more piece is constituted, being provided with linear drives parts between the two adjacent extending arms of joint to realize the retraction of two joint extending arms or to stretch out, described electric block is fixedly installed on the outermost end of revoliving arm.
Described linear drives parts are electricity push rod, oil cylinder or cylinder.
Described revoliving arm is made up of two joints or three joint extending arms, and extending arm realizes relative retraction under hydraulic oil cylinder driving or stretches out.
The controlling organization of described oil cylinder includes double contact switch, and two pairs of contacts of described double contact switch are respectively by the hydraulic pump power supply circuits of catalyst and oil cylinder with oil circuit electromagnetic valve is controlled is connected.
Compared with prior art, the beneficial effects of the utility model are:
Extending arm is used and wears formula, the stress of entirety is effectively ensured, simplify external structure simultaneously, and electric block is directly fixedly installed, the relative orbit simplifying electric block moves setting, effectively controls overall processing cost, by the movement that linear drives parts driving extending arm is axial, the most spatially constitute and evade, improve its range.
Accompanying drawing explanation
Fig. 1 show the structural representation of telescopic boom cantilever crane of the present utility model;
Fig. 2 show performance analysis figure;
Fig. 3 show control circuit figure.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.Should be appreciated that specific embodiment described herein, only in order to explain this utility model, is not used to limit this utility model.
As Figure 1-3, telescopic boom cantilever crane of the present utility model includes column 1, be arranged on the upside of described column and the revoliving arm 2 that can rotate in the horizontal direction relative to described column and the electric block 3 for article hoisting, wherein, the extending arm 21,22 that described revoliving arm is worn successively by two joints is constituted, being provided with linear drives parts between the two adjacent extending arms of joint to realize the retraction of two joint extending arms or to stretch out, described electric block is fixedly installed on the outermost end of revoliving arm 22.Wherein said linear drives parts are electricity push rod, oil cylinder or cylinder.
Extending arm is used and wears formula, i.e. bushing type design, the stress of entirety is effectively ensured, simplifying external structure simultaneously, and be directly fixedly installed by electric block, the relative orbit simplifying electric block moves setting, effectively control overall processing cost, by the movement that linear drives parts driving extending arm is axial, the most spatially constitute and evade, improve its range.
As shown in Figure 2, P, Q respectively second section extending arm retraction first segment extending arm and rotational trajectory when stretching out in figure, assume that N, O are two positions of mobile object needed for technique, have a pillar that the operation of revoliving arm is constituted at M to interfere, J, K, L are that barrier compact district can not be passed through, then cantilever crane object at N of slinging needs in second section extending arm retraction first segment, makes that brachium is the shortest avoids barrier M, is rotated again at O to stretch out second section extending arm and reaches O position and can complete carrying.
For realizing safely and effectively controlling, as a example by hydraulic oil cylinder driving, the controlling organization of described oil cylinder includes double contact switch, and two pairs of contacts of described double contact switch are respectively by the hydraulic pump power supply circuits of catalyst and oil cylinder with oil circuit electromagnetic valve is controlled is connected.Specifically, as shown in Figure 3, A1, A2 is electromagnetic valve, K1 is contacts of contactor,-K1 is contactor coil,-M1 is hydraulic pump, S1, S2 is double contact switch, correspondence extends and retracts order respectively, when pressing double contact switch S1, contactor coil-K1 obtains electric, contacts of contactor K1 closes, hydraulic pump M1 works, oil pressure is provided, the coil of electromagnetic valve A1 obtains electric simultaneously, the oil pressure that hydraulic pump produces enters corresponding oil cylinder to export corresponding action by electromagnetic valve A1, i.e., piston rod ejects drive second section extending arm and stretches out, Panasonic's button stops stretching out, stop stretching out to extreme position, in like manner press S2, second section extending arm is retracted.Utilize double contact switch to realize hydraulic pump and action output Synchronization Control, simplify control circuit, and effectively control the work of hydraulic pump, its energy saving can be effectively improved.
Certainly, above-described embodiment be only by two joint arrange as a example by carry out exemplary illustrated, it is also possible to revoliving arm is set to three joints or four joints, above-mentioned purpose can be realized equally.
The above is only preferred implementation of the present utility model; it should be noted that; for those skilled in the art; on the premise of without departing from this utility model principle; can also make some improvements and modifications, these improvements and modifications also should be regarded as protection domain of the present utility model.
