Abstract

The invention discloses a multistage piston lifting frame. The multistage piston lifting frame comprises a hydraulic pump, a multistage piston hydraulic cylinder, a supporting framework, a multi-section telescopic sleeve and a top flat plate, wherein the multi-section telescopic sleeve is formed by sequentially connecting a plurality of sections of tubes of which the diameters are in an increasing order; the multistage piston hydraulic cylinder is arranged in the middle of the supporting framework, and comprises a multistage piston which is vertical upwards; the top flat plate is horizontally arranged at the upper end of the multistage piston; the multi-section telescopic sleeve is vertically arranged between four corners of the top flat plate and the supporting framework; the hydraulic pump is connected with a hydraulic valve; the hydraulic valve is connected with the multistage piston hydraulic cylinder to control the stretch of the multistage piston hydraulic cylinder. Therefore, the multistage piston lifting frame has the advantages that the stability of the top flat plate in the lifting process is improved by adopting the multi-section telescopic sleeve, and the multistage piston lifting frame is small in size after contraction, and is convenient to move, simple in structure and convenient to maintain.

Description

A kind of multi-level piston crane
Technical field
The present invention relates to crane design field, particularly relate to a kind of multi-level piston crane.
Background technology
Conventional elevator mainly refers to folding arm hydraulic hoist and scissor physical construction bay-lift.In addition, also have a kind of elevator to be piston hydraulic cylinder upright type lifting machine, application little, mainly because piston hydraulic cylinder upright type lifting machine poor stability, piston hydraulic cylinder cannot be adopted to coordinate separately lifting board to use.
In order to the stability of jigger lifting piston hydraulic actuating cylinder upright type lifting machine, 4 auxiliary columns will be set usually between lifting board and bottom bracket.The constant height of column, lifting board is under the promotion of piston hydraulic cylinder, slide up and down along column, the top of column is exactly the upper limit of lifting board, and the rising therefore in order to improve elevator is formed, higher column must be adopted, the volume of elevator is increased, and cannot reduce, weight is large, cost is high, and mobile inconvenience.
Summary of the invention
The technical matters that the present invention mainly solves is to provide a kind of multi-level piston crane, compact, and stability is high, conveniently moving.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of multi-level piston crane, comprise: Hydraulic Pump, multi-level piston hydraulic actuating cylinder, support frame, multi-joint telescoping sleeve pipe and head slab, described multi-joint telescoping sleeve pipe is connected in sequence by the bobbin that several sections of diameter is descending, described multi-level piston hydraulic actuating cylinder is arranged on the centre of support frame, described multi-level piston hydraulic actuating cylinder comprises vertical multi-level piston upward, described head slab is horizontally set on the upper end of multi-level piston, described multi-joint telescoping sleeve pipe is vertically arranged on four of head slab between corner and the upper surface of support frame respectively, described Hydraulic Pump is connected with a hydraulic valve, described hydraulic valve is connected to control it and stretches with multi-level piston hydraulic actuating cylinder.
In a preferred embodiment of the present invention, described Hydraulic Pump is arranged on the inside of support frame.
In a preferred embodiment of the present invention, in described support frame, be also provided with a hydraulic reservoir be connected with Hydraulic Pump.
In a preferred embodiment of the present invention, the bottom of described support frame is also provided with wheel.
The invention has the beneficial effects as follows: a kind of multi-level piston crane that the present invention points out, employing multi-joint telescoping sleeve pipe improves the stability in head slab lifting process, and compact after shrinking, and be convenient to mobile, structure is simple, easy to maintenance.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of a kind of multi-level piston crane one of the present invention preferred embodiment;
In accompanying drawing, the mark of each parts is as follows: 1, Hydraulic Pump, and 2, multi-level piston hydraulic actuating cylinder, 3, support frame, 4, multi-joint telescoping sleeve pipe, 5, head slab, 11, hydraulic valve, 12, hydraulic reservoir.
Detailed description of the invention
Be clearly and completely described to the technical scheme in the embodiment of the present invention below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, the embodiment of the present invention comprises:
A kind of multi-level piston crane, comprise: Hydraulic Pump 1, multi-level piston hydraulic actuating cylinder 2, support frame 3, multi-joint telescoping sleeve pipe 4 and head slab 5, described multi-joint telescoping sleeve pipe 4 is connected in sequence by the bobbin that several sections of diameter is descending, described multi-level piston hydraulic actuating cylinder 2 is arranged on the centre of support frame 3, described multi-level piston hydraulic actuating cylinder 2 comprises vertical multi-level piston upward, described head slab 5 is horizontally set on the upper end of multi-level piston, described multi-joint telescoping sleeve pipe 4 is vertically arranged between four corners of head slab 5 and the upper surface of support frame 3 respectively, described Hydraulic Pump 1 is connected with a hydraulic valve 11, described hydraulic valve 11 is connected to control it and stretches with multi-level piston hydraulic actuating cylinder 2, the flexible lifting having driven head slab 5 of multi-level piston, and multi-joint telescoping sleeve pipe 4 stretches and provides supplemental support to head slab 5 thereupon, reduce, the shake of head slab 5, improve the stability in its lifting process, and head slab 5 is when dropping to nadir, multi-joint telescoping sleeve pipe 4 has also decreased height, reduce overall height, be convenient to mobile and transport.
A kind of multi-level piston crane of the present invention compact, described Hydraulic Pump 1 is arranged on the inside of support frame 3, good to the protectiveness of Hydraulic Pump 1.
Further, be also provided with a hydraulic reservoir 12 be connected with Hydraulic Pump 1 in described support frame 3, do not take additional space.
Further, the bottom of described support frame 3 is also provided with wheel, facilitate the movement of support frame 3, the stability of support frame 3 during in order to improve lifting, increase part can also to scatter and to the fixed mount of downward-extension around support frame 3, this type of fixed mount is many to be applied on hoisting crane and elevator, and the Creative Design of non-invention, does not repeat here.
In sum, a kind of multi-level piston crane that the present invention points out, volume is little, and be convenient to transport and adjustment, the stability of lifting is high, and sound construction is with low cost, easy to maintenance.
