Abstract

The utility model relates to a stair lifting device, which is composed of a pair of upright posts with unequal heights, a telescopic rod and a driving mechanism which is combined on the telescopic rod, wherein, the upright posts are abutted under the stair and both ends of the telescopic rod are respectively connected to both of the two upright posts. The length of the telescopic rod can be adjusted and thus the distance between both of the two upright posts can be changed. In addition, the telescopic rod can be driven by the driving mechanism and the upright posts can be linked to do the adjustment of lengthwise lengths. Thus both of the two upright posts can be adjusted according to the inclination degree of a supporting surface on the bottom of the stair and the needed overhead height. Thereby, a lifting single-purpose apparatus for the installation operations of the stairs with different heights and inclination angles is formed, and the inconvenience of the previous stair installation operations can be solved.

Description

Stair are risen device

The utility model relates to a kind of stair and rises device, and this device is convenient on the precalculated position of stair frame height when constructing when heavy stair are installed.

When architecture construction, according to the normal mounting operation of stair, the dealer generally all be earlier with stair according to the size of design and selected material, pattern make in advance finish after, again stair are transported to the place that desire installs and implement assembled on site.

When general installation exercise, stair must be praised to the inclination angle of the height of setting by manpower in advance, and then carry out winding; Yet stair are in order to strengthen soundness itself, guarantee the safety used, so all be to make with abundant material generally, also therefore, it is normally very thick and heavy to put in order the tool stair.In the installation exercise process, the mode that stair must be praised with personnel or temporarily seek supporter with the high position to assembling of stair frame could removal up to finishing installation; Well imagine that the mode of praising with personnel is labor intensive not only, and physical limited because of personnel, and can't allow stair stably remain on the ad-hoc location for a long time, and cause the inconvenience of installation exercise, also may influence the quality that stair are installed simultaneously.In addition, seek the mode of the high stair of supporter frame temporarily,, may not just can find all suitable supporter of long (height) degree and enabling capabilities immediately instantly, so also be not to be a good solution though can save the waste on the manpower.

It is a kind of when the stair operation is installed that main purpose of the present utility model is to provide, and equipment is risen in the stair special use that goes for differing heights and inclination angle.

For reaching above-mentioned purpose, the utility model system proposes a kind of stair and rises device, this rise device system by: a pair of in order to being resisted against the stair below, and the column that does not highly wait, two ends are linked to the expansion link of two columns respectively and the transmission mechanism that is incorporated on the expansion link is formed; Expansion link can be adjusted length and change distance between two columns, adds that expansion link also can drive and the interlock column is done the adjusting of longitudinal length via transmission mechanism, allows two columns can be according to the gradient of stair bottom support face and required built on stiltsly highly adjust.

The utlity model has following good effect: by the length adjustment of column and expansion link, allow stair rise and be installed on and play the part of the work that stair are lifted on the top in the stair installation exercise, solve the inconvenience when the stair operation is installed in the past.

Accompanying drawing provides embodiment of the present utility model.

Below in conjunction with accompanying drawing the utility model is elaborated:

Please consulting Fig. 1, Fig. 2 simultaneously, is to disclose the preferred embodiment that these stair are risen device among the figure, this rise device be at least by a: column 10,10 ', an expansion link 20 and a transmission mechanism 30 formed; As shown in the figure, with column 10, it includes a pipe spreader 11, that is axially arranged with guide screw groove 111 and places the interior driving screw 12 of pipe spreader 11, and a movable jacking block 13 that is hubbed at driving screw 12 tops is formed; By guide screw groove 111 meshing relation with driving screw 12, allow driving screw 12 rotated by external force and convert axial linear movement to respect to pipe spreader 11, change the total length of whole column 11; And movable jacking block 13 is to be hubbed in the start groove 121 of guide screw groove upper end by a pivot spare 14, allows movable jacking block 13 become a revolving part that is incorporated in the start groove 121.

And expansion link 20 is by two axial 21,22 compositions of inside and outside bar of socket each other, the ora terminalis place of inside and outside

bar

21,22 respectively be provided with a proper

engageable driving screw

12,12 in two columns '

gear

23,24;

As for 30 of transmission mechanisms is the driven parts 31 that are incorporated on the expansion link 20 by, and order about driven parts 31 starts, order about expansion link 20 and make the power input block of spinning motion (handle 32 as shown in FIG.), allow the gear 23 at expansion link 20 two ends, 24 drive via rotation driving screw 12,12 ' with respect to pipe spreader 11 overhanging or in contract.When implementing, driven parts 31 can be 311,312 compositions of a plurality of as shown in FIG. helical gears that are engaged with each other, and wherein a helical gear 311 is to be incorporated into expansion link 20, and another helical gear 312 then is engaged with and becomes continuous action relation; And the power input block can be a handle 32 that is incorporated on the helical gear 312, this handle 32 is to be provided with the polygon connecting rod 321 and cover access slot 313 of fit each other with helical gear 312 coupling, and one forms from the force rod 322 of connecting rod 321 turnover extensions; Allow force rod 321 can order about helical gear 311,312 rotation through outer dynamic braking, so allow driving screw 12,12 ' with respect to pipe spreader 11,11 ' axial linear movement.

Gear

23,24 for fear of expansion link 20 two ends is exposed to the external world with helical gear 311,312, this creation system more is provided with a housing 40 that covers at its outside, is infected with in

gear

23,24 and helical gear 311 to prevent dirt dust, on 312, the normal to each other movement relation of influence.

This creation is a kind of when being used to install thick and heavy stair, the high stair of frame rise device, by above-mentioned formation, because column 10,10 ' can change entire length (as shown in Figure 3) via adjustment, simultaneously also can by expansion link 20 change two columns 10,10 ' distance (as shown in Figure 4), the inclination angle that two columns, 10,10 ' top line is presented acquires change; Therefore, when implementing to apply to support stair 50 installation exercises, the height and the inclination angle that cooperate stair to install, rising device can be by the adjustment at bearing height and inclination angle, and supporting plane 131 on the movable jacking block 13 is close on the inclined-plane 51 of stair 50 lower edges (as shown in Figure 5).Hence one can see that, and this creation is a kind ofly can play the part of the work that stair 50 are lifted on the top in the stair installation exercise, replaces when not having this special use in the past and rising equipment, in the inconvenience of installing in the stair operation.

See also Fig. 6, this is created when implementing, the power input block except can handle 32 with manual operation, can also drive motor 33 as the power source of rising device, adjust between member bearing height and support the inclination angle in electronic mode.

The above person is the preferred embodiment of the utility model to the greatest extent, is not the scope that is used for limiting the utility model enforcement.All equalizations of being done according to the utility model claim change and modify, and are all this patent scope and contain.
