Abstract

The utility model discloses a lifting guardrail which is composed of a guardrail crossbeam (1), guardrail upright columns (7), a lifting oil cylinder (2) and an operation tabletop (3). The guardrail upright column (7) are respectively hinged with the guardrail crossbeam (1) and the operation tabletop (3). Two ends of the lifting oil cylinder (2) are respectively hinged with the operation tabletop (3) and the guardrail upright columns (7). The guardrail crossbeam (1) and the guardrail upright columns (7) form a parallelogram structure. The lifting guardrail used by lifting platform according to the utility model can conveniently lift and drop the safety barrier for satisfying the frequent lifting and descending operation of the safety barrier, which are required on the operation platform. Furthermore the lifting guardrail has the advantages of reliable safety and high efficiency.

Description

A kind of elevating guardrail
Technical field
The utility model relates to a kind of lift platform elevating guardrail.
Background technology
Lift platform is a kind of conveying equipment and the working platform that can realize lifting at a kind of removable and work top of all trades and professions extensive use.In order to guarantee safety, on working platform, usually safety barrier to be installed in the course of work.But for convenience platform top workpiece loading and unloading, need to pull down guardrail sometimes, after loading and unloading are finished, load onto guardrail again.Install and remove guardrail continually, reduced operating efficiency, particularly be in when high, also can therefore produce dangerous accident at lift platform.
Summary of the invention
At the deficiencies in the prior art, the elevating guardrail that the utility model provides a kind of lift platform to use can rise easily and falls safety barrier, to satisfy the work that the needs safety barrier frequently rises and falls on working platform according to job requirement, and safe and reliable, the efficient height.
The utility model adopts following technical scheme: a kind of elevating guardrail, and it is made up of guardrail cross beams, fence upright, hoist cylinder, work top, and described fence upright is hinged with guardrail cross beams and work top respectively; Hoist cylinder two ends are hinged with work top and fence upright respectively; Form parallelogram sturcutre between described guardrail cross beams and the fence upright.
Form some parallelogram sturcutres between described guardrail cross beams and the fence upright, be provided with several hoist cylinders between described fence upright and the working platform; Described work top bottom-hinged has the lifting that is hinged and connected with the chassis to cut yoke, and described two liftings are cut the yoke intersection and are provided with the lifting platform oil cylinder, and the lifting platform oil cylinder is cut yoke with two liftings respectively and is hinged and connected; Described work top bottom is provided with two chassis relatively, and the chassis is provided with corresponding lifting and cuts yoke and lifting platform oil cylinder.The utlity model has following beneficial effect: the utility model is simple in structure, is easy to the folding and unfolding guardrail by hoist cylinder and is convenient to safeguard, has improved safety and operating efficiency.Be provided with several hoist cylinders between fence upright and the working platform and ensured stability of the present utility model and safety.
Description of drawings
Fig. 1 is the utility model structural representation
The specific embodiment
As shown in Figure 1, a kind of elevating guardrail, it is made up of guardrail cross beams 1, fence upright 7, hoist cylinder 2, work top 3, and described fence upright 7 is hinged with guardrail cross beams 1 and work top 3 respectively; Hoist cylinder 2 two ends are hinged with work top 3 and fence upright 7 respectively; Form some parallelogram sturcutres between guardrail cross beams 1 and the fence upright 7, all use hinged between the guardrail cross beams 1 of lift platform guardrail and fence upright 7 and fence upright 7 and the work top 3, fence upright can be swung around hinge two axis, thereby changes variable angle between fence upright and work top.Between fence upright 7 and working platform 3, several hoist cylinders 2 are installed; When oil cylinder was in extended configuration, then fence upright 7 was in vertical raised position, and at this moment, the platform guardrail is in the rise state; And when oil cylinder was in contraction state, then fence upright 7 can rotate around the hinge between column below and work top, and guardrail is in falls the position.When hoist cylinder 2 stretched, then fence upright 4 can be around the hinge swing, and the angle that fence upright 4 and work top are 3 also changes thereupon, and the parallelogram shape that forms between guardrail cross beams 1 and the fence upright 4 also changes.Thereby the height of guardrail also just rises thereupon and descends.Work top 3 bottom-hinged have the lifting that is hinged and connected with chassis 6 to cut yoke 4, two liftings to cut yoke 4 intersections and be provided with lifting platform oil cylinder 5, and lifting platform oil cylinder 5 is cut yoke 4 with two liftings respectively and is hinged and connected.Work top 3 bottoms are provided with two chassis 6 relatively, and chassis 6 is provided with corresponding lifting and cuts yoke 4 and lifting platform oil cylinder 5.Be connected with gauge tap on the oil cylinder.

Claims (4)
