Abstract

The utility model discloses a hydraulic lifter, which comprises a working platform, more than two scissors type lifting mechanisms, a hydraulic mechanism, an electric control mechanism and a chassis. Frames are arranged on the peripheries of the upper end and the lower end of each scissors type lifting mechanism, and a stepped plate extends from one end of each frame; and the stepped plates are gradually far away from the frames from the top to the bottom in sequence. The frame at the undermost end of the scissors type lifting mechanism serves as the chassis, and a working platform positioning device is arranged on the chassis. A universal wheel set and a positioning wheel set are arranged at the bottom end of the chassis. A towing ring is arranged on one side of the chassis, and a dismountable hand pushrod is arranged on the other side of the chassis. The scissors structure of the hydraulic lifter has contraction and folding functions, so as to reduce volume. The hydraulic lifter lifts upwards under a load; the folding steps are helpful for storage and climbing; and the hydraulic lifter can be easily manually pushed to another place.

Description

Hydraulic hoist

Technical field

The utility model relates to hydraulic hoist, and specifically, the utility model relates to a kind of stepped folding hydraulic hoist.

Background technology

It is that 200420033555.8 Chinese patent discloses a kind of hand hydraulic hoist of scissor-type that loads and unloads when being used for the product container transshipment that name is called " the hand hydraulic hoist of scissor-type ", the patent No., this elevator adopts scissors lever type mechanical structure, workplatform relies on four hydraulic oil cylinder driving that are articulated in the scissors fork, the two ends of four oil cylinders are articulated on the crotch respectively, connect by the circular shaft that connects crotch between the oil cylinder, scissors is pitched the effect of in fact lifting mechanism.

Name is called " hydraulic elevating platform ", the patent No. be 200420079729.4 Chinese patent disclose a kind of can be supporting multi-functional, hydraulic elevating platform safe in utilization simple in structure, comprise job platform, lifting mechanism, hydraulic gear, electric control mechanism, chassis etc., lifting mechanism is that two groups of jibs that are the arrangement of " X " shape are formed by stacking, the two ends of the mechanical connection job platform bottom surface, two ends of the jib of going up most, the two ends of the two ends mechanical connection chassis surface of the jib, central part on the chassis is provided with hydraulic gear, the piston rod of hydraulic ram is connected and supports on the strut rail, outside electric control mechanism is installed in.

General ladder can only be climbed for personnel, and can not carry weight, present common ladder, no matter be single ladder or double ladder, only can do some up and down to highly impalpable light thing for personnel, and if ascend a height again again with weight that (as the certain altitude of rising progressively of 100kg～200kg), then ladder is just powerless, and aforesaid elevator, after rising to height, if the people will get off, then goods also must get off simultaneously, bring inconvenience to real work, reduce work efficiency.

At the relative deficiency of prior art, the utility model is proposed.

The utility model content

The purpose of this utility model is the deficiency that exists at prior art, and a kind of hydraulic hoist with ladder is provided.

For realizing above-mentioned utility model purpose, the technical scheme of hydraulic hoist provided by the utility model is: a kind of hydraulic hoist, comprise work top, two groups above cut fork-shaped lifting mechanism, hydraulic gear, electric control mechanism, chassis, cut fork-shaped lifting mechanism upper and lower end for every group and be equipped with framework all around, an end of all frameworks is outward extended with stepped plate.

Stepped plate is from top to bottom successively gradually away from framework.

The framework of cutting fork-shaped lifting mechanism lowermost end is as the chassis, and the chassis is provided with the work top registration device.

The bottom, chassis is provided with one group of cardan wheel and one group of directional wheel.

Chassis one side is provided with eye hitch, and opposite side is provided with the detouchable handspike.

The beneficial effects of the utility model are:

The fork structure of cutting of the present utility model has the contraction folder function, reduced volume, and upwards lifting under the heavy burden situation, folding ladder is convenient to collection and up and down; Can easily carry out, shift local with manpower.

Description of drawings

Fig. 1 is an overall structure scheme drawing of the present utility model.

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in detail.

The specific embodiment

Fig. 1 shows overall structure of the present utility model, as shown in Figure 1, the utility model hydraulic hoist, comprise work top 1, two groups of above fork-shaped lifting mechanisms 2 of cutting, hydraulic gear 3, the electric control mechanism (not shown), every group cut fork-shaped lifting mechanism 2 on, be equipped with framework 5 around the lower end, one end of all frameworks 5 is outward extended with stepped plate 6, the framework of cutting fork-shaped lifting mechanism 2 lowermost ends is as chassis 4, stepped plate 6 is from top to bottom successively gradually away from framework 5, so when cutting 2 rises of fork-shaped lifting mechanism, stepped plate 6 is natural shaped to be stair, the staff can be retained in weight on the work top 1, go down from stepped plate 6 voluntarily, avoided and want weight is stayed eminence, can not use elevator to leave the contradiction of work top again.

Chassis 4 is provided with the registration device 7 that work top 1 is carried out stationary positioned, 4 bottom is provided with one group of cardan wheel 8 and one group of directional wheel (not shown) on the chassis, cooperate the eye hitch 9 of chassis 4 one sides setting and the detouchable handspike 10 that opposite side is provided with, easily to moving under the elevator loading situation.

The present technique key is to utilize in the fork type elevator structure, and its diagonal of a parallelogram can be along with the rising of elevator and decline and about the level, thereby forms that ladder stretches and folding, for about the personnel.

When ladder is folding, weight can be put on its work top, again platform is risen, the people can be on ladder down and goods can rest on height, must not drop to ground, work finishes, and will shift behind the machine folding storage.

The utility model also can have other variation; as well known to the skilled person; the foregoing description only plays the exemplary role in the above-mentioned utility model protection scope; for those of ordinary skills; also have a lot of conventional distortion and other embodiment in the protection domain that the utility model limited, these distortion and embodiment will be within the protection domains that the utility model awaits the reply.
