Abstract
The invention discloses an elevating guardrail which is composed of a guardrail beam (1), a guardrail stand column (7), an elevating cylinder (2) and a working table board (3), wherein the guardrail stand column (7) is respectively hinged with the guardrail beam (1) and the working table board (3), two ends of the elevating cylinder (2) are respectively hinged with the working table board (3) and the guardrail stand column (7), and the guardrail beam (1) and the guardrail stand column (7) form a parallelogram structure. The invention provides the elevating guardrail for elevating platforms, which can conveniently elevate and lower the safe guardrail according to working requirements so as to satisfy the condition that a working platform needs a safe guardrail to frequently elevate and lower; in addition, the elevating guardrail is safe and reliable and has high efficiency.
Description
Technical field
The present invention relates to a kind of lifting table elevating guardrail.
Background technology
Lifting table is a kind of load transfer device and the workplatform that can realize lifting at a kind of removable and work top of all trades and professions widespread use.In order to guarantee safety, on workplatform, usually safety barrier to be installed in the working process.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 work efficiency, particularly be in when high, also can therefore produce dangerous accident at lifting table.
Summary of the invention
At the deficiencies in the prior art, the invention provides the elevating guardrail that a kind of lifting table is used, can rise easily and fall safety barrier according to job requirement, to satisfy the work that the needs safety barrier frequently rises and falls on workplatform, and safe and reliable, the efficient height.
The present invention 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 workplatform; 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 present invention has following beneficial effect: the present invention is simple in structure, is easy to the folding and unfolding guardrail by hoist cylinder and is convenient to safeguard, has improved safety and work efficiency.Be provided with several hoist cylinders between fence upright and the workplatform and ensured stability of the present invention and safety.
Description of drawings
Fig. 1 is a structural representation of the present invention
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 lifting table 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 workplatform 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 master cock on the oil cylinder.
Claims (4)
