The specific embodiment

For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

As shown in Figure 1; The utility model bear a heavy burden climb the building device comprise be fixed on two ends about each two interior cat ladder wheels 1 with about each two outer cat ladders wheels 2, interior cat ladder wheel 1 with link to each other through chassis connecting rod 5 between outer cat ladder takes turns 2, a chassis 4 is installed above the chassis connecting rod 5; Two worm screw casees 3 about having on the chassis 4; Having motor to climb the building device for this heavy burden in the worm screw case 3 provides power, both sides worm screw case 3 respectively with heavy burden climb building device middle part relatively the sprocket wheel 6 of both sides engage, on the sprocket wheel 6 at middle part chain 7 is arranged; Chain 7 engages formation one osed top drive line with the sprocket wheel 6 at two ends, the outer cat ladder wheel 2 at two ends is fixed on the sprocket wheel 6 at two ends.

Shown in Figure 2ly climb the building device scheme drawing of on stair, creeping for the utility model bears a heavy burden, its transmission process is that worm screw case 3 drives that intermediate chain wheels 6, intermediate chain wheel 6 drive chains 7, chain 7 drives the outer cat ladder wheel 2 that is fixed on two ends sprocket wheel 6 and rotates.Inside and outside cat ladder wheel all is made up of three equally distributed cat ladders wheel bars in the present embodiment, in the practical application based on the gradient of different stair with highly can adjust cat ladder and take turns the quantity of bar in taking turns.The building device is climbed in this heavy burden makes the motor in the worm screw case 3 rotate through power supply; Motor is climbed the building device for this heavy burden power is provided; Drive outer cat ladder wheel 2 and rotate, take turns creeping of bar through outer cat ladder on the outer cat ladder wheel 2 then, make climbing ladder apparatus reach the purpose of stair activity.

The building device is climbed in heavy burden, and to climb up the process of stair following: as shown in Figure 3, climb up stair before, the motor in the worm screw case 3 produces certain moment, overcomes the gravity of climbing ladder apparatus, prevents that inside and outside cat ladder wheel from rotating counterclockwise and fall.When beginning to climb up stair, cat ladder wheel bar is perpendicular to the ground in the climbing ladder apparatus, and outer cat ladder wheel bar is parallel with stair face 8, and the control motor in the worm screw case 3 just changes; Drive the motion of intermediate chain wheel 6 cws, drive chain 7, spur outer cat ladder wheel 2 and clockwise rotate; After rotating to an angle, outer cat ladder wheel bar contacts with stair face 8, and is as shown in Figure 4; Outer cat ladder wheel bar is rotated further and drives whole climbing ladder apparatus motion, rotates to vertical with stair face 8, as shown in Figure 5 up to outer cat ladder wheel bar.Intermediate chain wheel 6 is rotated further and drives chain 7 motions simultaneously, and cat ladder is taken turns 1 clickwise in driving, and is parallel with stair face 8 up to interior cat ladder wheel bar, at this moment climbs the work of a ladder and accomplishes, and motor works on and promotes this device upstairs then.

The building device is climbed in heavy burden, and to climb down the process of stair following: before climbing down stair, the motor of worm screw case 3 produces certain moment, and the gravity that overcomes climbing ladder apparatus prevents that inside and outside cat ladder wheel from rotating counterclockwise.When beginning to climb down stair, outer cat ladder wheel bar is vertical with stair face 8, and interior cat ladder wheel bar is parallel with stair face 8; As shown in Figure 5, the control motor of worm screw case 3 rotates counterclockwise and drives the motion of intermediate chain wheel 6 conter clockwises at this moment, drives chain 7; Spur outer cat ladder wheel 2 and rotate counterclockwise, after rotating to an angle, interior cat ladder wheel bar and stair face 8 are unsettled; As shown in Figure 4, when outer cat ladder wheel bar was rotated further, the contact point of outer cat ladder wheel bar and stair face 8 was fixed; Also conter clockwise motion of interior cat ladder wheel 1 rotates to vertically with stair face 8 up to interior cat ladder wheel bar, it is parallel with stair face 8 that this moment, outer cat ladder was taken turns bar; As shown in Figure 3, at this moment climb down the work of single order stair and accomplish, motor works on and promotes this device downstairs then.

The utility model is simple in structure, realizes easily, when delivering than heavy articles to high-rise building, can reduce people's manual labor in large quantities, brings more convenience for people's live and work.

Although the embodiment of the utility model is open as above; But it is not limited only to listed utilization in specification sheets and the embodiment; It can be applied to the field of various suitable the utility model fully, for being familiar with those skilled in the art, can easily realize other modification; Therefore under the universal that does not deviate from claim and equivalency range and limited, the legend that the utility model is not limited to specific details and illustrates here and describe.
