The utility model provides an improved hydraulic lifting work ladder with an extendable platform with a self-locking function, and during work at height, particularly maintenance on a facility with inapproachable parts, the extendable platform can be fixed at any position. The hydraulic lifting work ladder consists of a car body, an electrohydraulic control box, a lifting mechanism, a fixed platform, a sprocket wheel-screw self-locking mechanism and the extendable platform. The improvement of the hydraulic lifting work ladder is that the sprocket wheel-screw self-locking mechanism is mounted in the hydraulic lifting work ladder, the sprocket wheel-screw self-locking mechanism consists of a big sprocket wheel, a small sprocket wheel, a chain, a screw, a threaded sleeve, a link rod, a bearing pedestal, a handle, a drive shaft, a sprocket wheel support and a protective cover, and consequently, the extendable platform can be self-locked at any position in the process of movement and can quickly, accurately and safely approach the inapproachable part, so that the facility can be maintained.

Description

A kind of band extends flat-bed hydraulic lifting working stand
Technical field
The present invention relates to a kind of hydraulic lifting operating mechanism, especially a kind of band extends flat-bed hydraulic lifting working stand.
Background technology
Civilian and military aircraft, airport, harbour, factory building, warehouse etc. need in use its facility is safeguarded that for higher position, especially some inaccessible positions are difficult for satisfying maintenance requirement with common working stand.
It in use is first crawl electric up-down control knob that existing band extends flat-bed hydraulic lifting working stand, make fixed platform rise to desired height, the rear that stands in fixed platform then forwards moves to the working position that needs maintenance with the pushing hands that hand push extension platform moves guard rail, facility is safeguarded, the extension platform can only carry out spacing with modes such as latches in several position when forwards mobile, can not carry out spacing at an arbitrary position, because action of inertia, might push away the position and break facility, and can not guarantee in its spacing position when shifting onto, need repeatedly moving body and adjust to extend the flat-bed position and just can reach and not only shift position but also can be onto to its spacing effect, such mode of operation poor stability, the working costs effort.
Summary of the invention
The purpose of this utility model provides a kind of improvement and extends flat-bed hydraulic lifting working stand, it extends platform and has auto-lock function, aloft during operation, when especially the facility at some inaccessible positions being safeguarded, extending platform can be spacing at an arbitrary position, has not only guaranteed safety but also improved work efficiency.
A kind of band of the utility model extends flat-bed hydraulic lifting working stand and is made up of car body, electricity-liquid control box, lifting mechanism, fixed platform, sprocket wheel screw rod self-locking device, extension platform six major parts.The improvements that its described band extends flat-bed hydraulic lifting working stand are to be provided with sprocket wheel screw rod self-locking device in the hydraulic lifting working stand, make extend platform can be spacing voluntarily at an arbitrary position in moving, fast, accurately, safely near inaccessible position, facility is safeguarded.
Described band extends the sprocket wheel screw rod self-locking device of flat-bed hydraulic lifting working stand and is made up of hinge wheel, minor sprocket, chain, screw rod, swivel nut, connecting rod, bearing seat, handle, transmission shaft, chain wheel support and protective case.Bearing seat is fixed on the side of fixed guide with pan head screw; one end of screw rod inserts in the hole of bearing seat; the other end and minor sprocket are fitted together with straight pin to be fixed; swivel nut is screwed on the screw rod; in the hole on the one end insertion swivel nut of connecting rod; the other end is fixed on the moving guide rail with flathead screw; hinge wheel is connected with minor sprocket with chain; handle inserts with being connected to of transmission shaft and is connected; protective case; the chain wheel support is fixed on the fixed platform; the anti-collision rubber disc is fixed on and extends on the platform; mobile upper roller; mobile bottom roller; mobile side wheel is installed on the moving guide rail; the fixation side roller; fixedly bottom roller is installed on the fixed guide, and mobile guard rail inserts with being connected to of fixed protection hurdle and is connected.In the time of need safeguarding the facility at inaccessible position, the clockwise direction turning handle, hinge wheel drives minor sprocket by chain gear and rotates, and screw rod rotates with minor sprocket, drives swivel nut moving linearly forward, driving the extension platform by connecting rod extends out forward, progressively near inaccessible position, the anti-collision rubber disc on extending platform is during near facility, and handle stops operating, it is spacing voluntarily to extend platform, and facility is safeguarded.Work finishes, and during the anticlockwise direction turning handle, extends platform and withdraws backward.
After adopting such structure because the latching characteristics of screw rod, swivel nut, make extend platform can be spacing voluntarily at an arbitrary position in moving; And hinge wheel, minor sprocket, chain gear can make the operator face inaccessible position, see clearly and extend the distance of platform, when extending platform, stop the rotation of handle at any time, extend the platform self-locking near the facility that needs to safeguard from facility, thereby, improved safety and work efficiency widely.
