Abstract
The invention relates to an anti-falling mechanism for a lifting platform, belongs to a safety protection device, and mainly solves the problem that a table top is out of control and descends when a chain of the conventional lifting platform is broken. The anti-falling mechanism comprises lifting bodies, hydraulic cylinders and lifting chains, wherein the lifting bodies are formed by movably superposing lath-shaped sections; each group of lifting body is provided with a hydraulic cylinder; the lifting chains are arranged between every two adjacent sections; and the side face of each section is provided with a protection steel wire rope. The anti-falling mechanism is provided with the protection steel wire ropes, and the table top cannot be out of control or suddenly descend but slowly descends to the lowest position under the matching action of the protection steel wire ropes and protection pulleys when the lifting chains are broken in the working process of the lifting platform, so that accidents are avoided, and the safety of personnel and articles on the platform is effectively ensured.
Description
Technical field
The present invention relates to the safety protection technique field, specifically a kind of anti-falling mechanism for lifting platform.
Background technology
The approval that hydraulic hoist is simple and reasonable with it, low cost of manufacture and hoisting speed obtain the relevant industries personage soon, the conventional elevator of replacement take electrical motor as power is widely used, but existing hydraulic hoist does not have anti-falling mechanism, if such elevating chain fracture in the course of the work, main table top will out of controlly cause unexpected decline, easily accidents caused, even cause serious life and property loss.At present, need a kind of anti-falling mechanism to avoid the generation of this type of accident.
Summary of the invention
The object of the present invention is to provide a kind of anti-falling mechanism for lifting platform, this device can be controlled main table top slow decreasing when the elevating chain fracture, prevents that main table top is out of control, thus the accident of avoiding.
The present invention solves the technical scheme that its technical matters takes: anti-falling mechanism for lifting platform, comprise lifting body, hydraulic actuating cylinder and elevating chain, it is characterized in that, described lifting body is made of the movable stack of lath-shaped section bar, and every group of lifting body is provided with a hydraulic actuating cylinder; Be provided with elevating chain between per two adjacent section bars, described elevating chain is walked around the lifting pulley that is positioned at the section bar upper end; The side of section bar is provided with the protection steel rope, and described protection steel rope one end is fixed on the section bar upper end in the section bar of living in outside, and the other end is walked around the section bar lower end that is fixedly attached to section bar of living in inboard behind the protection pulley of section bar of living in upper end.
Described protection steel rope is captiveed joint by wire line shoe with described section bar upper end.
Described protection steel rope is captiveed joint by wedge-shaped sleeve with described section bar lower end.
Described lifting body is made by high strength aluminum alloy.
The present invention compared with prior art; has following outstanding beneficial effect: simple in structure; match by protection steel rope and protection pulley; when suddenly fracture occurs in elevating chain in the working process; table top can unexpected decline out of control; but dropping to slowly extreme lower position, actv. has guaranteed the safety of personnel and article on the table top, has avoided accident.
Description of drawings
Fig. 1 is structural representation of the present invention.
Among the figure: 1 elevating chain, 2 hydraulic actuating cylinders, 3 section bars, 4 protection steel ropes, 5 protection pulleys, 6 lifting pulleys.
The specific embodiment
The invention will be further described below in conjunction with Figure of description:
As shown in Figure 1, anti-falling mechanism for lifting platform comprises lifting body, hydraulic actuating cylinder 2 and elevating chain 1, and described lifting body is made of the 3 movable stacks of lath-shaped section bar, and every group of lifting body is provided with a hydraulic actuating cylinder 2; Be provided with elevating chain 1 between per two adjacent section bars 3, described elevating chain 1 is walked around the lifting pulley 6 that is positioned at section bar 3 upper ends; The side of section bar 3 is provided with protection steel rope 4, and described protection steel rope 4 one ends are fixed on the section bar upper end in section bar of living in 3 outsides, and the other end is walked around the section bar lower end that is fixedly attached to section bar of living in 3 inboards behind the protection pulley 5 of section bar of living in 3 upper ends.
Described protection steel rope 4 is captiveed joint by wire line shoe with described section bar 3 upper ends.Described protection steel rope 4 is captiveed joint by wedge-shaped sleeve with described section bar 3 lower ends.Wire line shoe connects to be connected with wedge-shaped sleeve and is the present steel cord ends fixed form of commonly using, and is simple in structure, is connected firmly, with low cost.
Described section bar 3 is the high strength aluminum alloy lower mast.High strength aluminum alloy is sturdy and durable and quality is light, and is easy to operate, reliable operation.
When work top rises, rise at the effect lower sectional material 3 of hydraulic actuating cylinder 2, move on the lifting pulley 6 on the section bar 3, protect simultaneously pulley 5 to move on also.If elevating chain 1 fracture; table top will drive protection steel rope 4 and walk around protection pulley 5 when descending; every protection steel rope 4 all can involve two adjacent section bars 3 simultaneously; therefore unexpected decline can not occur in table top; but drop to slowly extreme lower position; actv. has guaranteed the safety of personnel and article on the table top, has avoided accident.
The above, principles more of the present invention just explain through diagrams, this specification sheets be not be the present invention to be confined to shown in described concrete structure and the Applicable scope, therefore every corresponding modify that might be utilized and equivalent all belong to the claim that the present invention applies for.
Except the described technical characterictic of specification sheets, all the other technical characterictics are those skilled in the art's known technology.
