Abstract
The utility model discloses a lifting device with a limiting support. The lifting device comprises an upper platform surface, a lower platform surface, an inner arm frame, an outer arm frame, an anti-falling device and the limiting support. The height is adjusted by adjusting angles of the inner arm frame and the outer arm frame through a motor. The anti-falling device prevents the upper platform surface from falling promptly after sudden outage, and accordingly prevents the lifting device and articles on the lifting device from being damaged and ensures life safety of operating workers. The limiting support is arranged on the lower platform surface and can effectively prevent the upper platform surface from falling and being contacted with the lower platform surface after failure of the anti-falling device. The lifting device with the limiting support has the advantages of being simple in structure, low in cost, high in security coefficient and the like.
Description
Technical field
The present invention relates to a kind of jacking system, or rather, is a kind of jacking system that has limited support.
Background technology
All be provided with dropproof device on the jacking system of the prior art; Preventing that upper table surface after the sudden power from descending rapidly damages article or operator's the life security on jacking system or the jacking system; But the complex structure of dropproof device; Cost is higher, and safety factor is not high enough, can not actv. article or operator's life and health safety on protection jacking system and the jacking system.
Chinese invention patent ZL 01247511.4 discloses a kind of elevator, comprises platform, chassis, cuts yoke, oil cylinder, goes up lower brace, pipe link, hydraulic efficiency pressure system; Two cut yoke rotates to be connected at the center and cuts fork; Cutting two of fork cuts yoke upper and lower end and platform, chassis and becomes to rotate respectively, is slidingly connected; Before and after connecting respectively, cuts last lower brace the corresponding yoke of cutting of fork; The cylinder body of oil cylinder rotates with lower brace and connects; One end of pipe link rotates with the piston rod of oil cylinder and connects, and the other end connects with last stull; The pipe link other end that connects with last stull than its end that connects with piston rod further from cutting the yoke center.But this elevator does not comprise limited support, and the safety system number is not high enough.
China disclosure of the Invention CN 200910152801.9 discloses a kind of multi-functional elevator; Comprise chassis assembly and bay-lift assembly; Chassis assembly and bay-lift inter-module are movably hinged scissors mechanism and support or drive the bay-lift assembly; Actuating device is set on the chassis assembly drives the flexible of scissors mechanism, actuating device is controlled by the controller of being located on the chassis assembly.Actuating device adopts the Worm-gear type retarder, and inside is provided with self-locking mechanism; The roll wheel assembly of band induction installation is set on the chassis assembly, and safety in utilization improves greatly.But this elevator does not have limited support equally, and safety factor is not high enough, causes very big threat for user's life and health.
Summary of the invention
The utility model mainly is to solve the existing in prior technology problem, thereby provides a kind of simple in structure, and cost is lower, the jacking system that has limited support that safety factor is higher.
The above-mentioned technical matters of the utility model mainly is able to solve through following technical proposals:
A kind of jacking system that has limited support, described jacking system comprise upper table surface, following table, interior jib, boom, dropproof device and limited support, and described limited support is arranged on following table up and down table top captive joint.
More excellent is, described limited support and following table are welded to connect, and welded structure can prevent effectively when upper table surface descends rapidly that comparatively firmly upper table surface from descending.
More excellent is, described jacking system comprises the limited support more than 2 or 2, and the support upper table surface that 2 or two above limited supports can be more firm is set, and further improves safety factor.
More excellent is, described jacking system comprises 4 limited supports, and preferred 4 limited supports of the jacking system of the utility model, 4 limited supports are arranged on four jiaos of following table.
Therefore, having of the jacking system that has limited support of the utility model is simple in structure, and cost is lower, and safety factor is than advantages such as height.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art; To do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below; Obviously, the accompanying drawing in describing below only is some embodiment of the utility model, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the perspective view of the jacking system that has spacing support of the utility model;
Fig. 2 is the perspective view of another direction of the jacking system that has spacing support of the utility model;
Fig. 3 is following table and the structural representation of limited support among Fig. 1;
Fig. 4 is the structural representation of upper table surface among Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
It is a kind of simple in structure that the utility model provides, and cost is lower, the jacking system that has limited support that safety factor is higher.
As shown in Figure 1; A kind of jacking system that has limited support; This jacking system comprises upper table surface 1, following table 2, interior jib 3, boom 4, dropproof device and 4 limited supports 5; Described limited support 5 is arranged on following table 2 up and down table tops 2 and is welded to connect, and 4 spacing supports 5 are arranged on four jiaos of following table 2.Behind dropproof failure of apparatus, upper table surface 1 descends always, when dropping to limited support 5 height, stops to descend, and reaches the article or the purpose of workman's life security on every side on protection jacking system and the jacking system.
