Abstract
A ladder able to move when it is used is composed of a supporting frame, a step-type ladder with manually manipulated two control wheels on its top, and 4 castors. Manipulating two control wheel is different modes can move the ladder in different mode, such as moving forward or backward and making a turn.
Description
Technical field:
The present invention relates in a kind of use movably ladder.
Background technology:
Known various ladder can only be placed on certain position, uses for the ascend operation person.But many times people need will shift from one place to another ladder in the diverse location operation, climb up and climb down, and will be very inconvenient.
Summary of the invention:
The technical problem that solves: in order to solve above-mentioned deficiency, the invention provides in a kind of use movably ladder, that is to say that the people can handle ladder as required and advance, retreats or turn on ladder, thereby mobile easily ladder arrives assigned address.
The technical scheme that adopts: main body of the present invention is made up of support and pedal ladder, and outer appearnce is like " people " font.There are two movable wheels the support lower end, and there are two power wheels the pedal ladder below, i.e. the present invention contacts with ground by four wheels, therefore can move on the ground.The pedal ladder upper end has two to control wheel, links to each other by two gears of chain with two power wheels outsides, and promptly each control wheel all can drive the power wheel rotation of homonymy.The people stands in when the operation ladder moves on the pedal, (as: shakes one or two control wheel by shaking the control wheel by different way; Shake forward or shake backward etc.), just can realize advancing, retreat or turning of ladder.The people also can be by the fixing control wheel of backstay device on ladder during operation, thereby ladder is fixed on as you were.
Beneficial effect: the present invention has broken through known various ladder can only be placed on the limitation that use certain position, the user can handle any direction of ladder to the plane and move on ladder, and can at any time ladder be fixed on job position, the person that greatly facilitates the ascend operation has improved operating efficiency.In addition, when not using, support and pedal ladder also can also be in the same place, to save the space.The present invention is a kind of brand-new ladder that has very much practical value.

Each component names: support (1), running-board bracket (2), power wheel (3), control wheel (4), chain (5), steering wheel (6), control wheel rocking handle (7), the pedal strong point (8), gear (9), top board (10), direction wheel carrier (11), ball axle (12), top plate supporting point (13), movable rack (14), pedal (15), rack beam (16), positioner (17), location rocking handle (18), backstay (19), locating shaft (20), locator protrusions (21), (22), hollow kerve (23) are colluded in the location, kerve lower end (24), kerve bayonet socket (25).
The specific embodiment:
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 7, control wheel (4) is fixed together with control wheel rocking handle (7), gear (9) is fixed together with power wheel (3), and control wheel (4) links to each other by chain (5) with gear (9), therefore shakes control wheel rocking handle (7) power wheel (3) is rotated.
As Fig. 8, shown in Figure 9, direction wheel carrier (11) is connected by ball axle (12) with support (1), that is to say, direction wheel carrier (11) can freely rotate.
As shown in Figure 1 and Figure 2, the people stands in that pedal (15) is gone up or is sitting in back to support (1) and all can handle ladder on the top board (10) and move: when both hands are simultaneously equidirectional when shaking two control wheel rocking handles (7), two power wheels (3) are to equidirectional rotation, and this moment, ladder moved forward or backward; When one hand shook one of them control wheel rocking handle (7), then the power wheel of homonymy (3) rotated, and at this moment both direction wheel (6) is adjusted direction automatically, thereby the realization ladder is turned forward or backward; When both hands shook two control wheel rocking handles (7) in the other direction simultaneously, two power wheels (3) rotated round about, and this moment, rotated in the ladder original place.That is to say, shake two control wheel rocking handles (7), ladder is moved to any direction on plane by different modes.
As Fig. 3, Fig. 4, Fig. 5, shown in Figure 6, when the operator shakes ladder assigned address and carries out operation, can pass through the fixed-site of positioner (17) with ladder.Positioner (17) is by location rocking handle (18), locating shaft (20) backstay (19) and location are colluded (22) and are formed (as shown in Figure 4), when shaking location rocking handle (18) to the top, backstay (19) also forwards the top to thereupon, being in control takes turns between the sawtooth of (4) (as shown in Figure 5), this moment is compression set position rocking handle (18) firmly, the location is colluded (22) and be stuck in locator protrusions (21) last (as shown in Figure 6), backstay (19) just is fixed between the sawtooth of control wheel (4), therefore control wheel (4) can not rotate, power wheel (3) can not rotate, and ladder just is fixed on the original place.Want the ramp period of the day from 11 p.m. to 1 a.m, firmly upwards shake earlier location rocking handle (18), make to locate and collude (22) and separate with locator protrusions (21) and get final product.Two control wheels (4) below is equipped with positioner (17), and the operator can fix one or two control wheel (4) as required.
As Figure 10, Figure 11, shown in Figure 12, ladder can be closed up at ordinary times to save the space.The upper end of movable rack (14) is provided with hollow kerve (23), and the two ends up and down of hollow kerve (23) are respectively kerve bayonet socket (25) and kerve lower end (24).Realize opening of ladder and close up by the motion of rack beam (16) in hollow kerve (23).When ladder is closed up, hollow kerve (23) can move upward along rack beam (16), top plate supporting point (13) also makes progress with the pedal strong point (8) thereupon, driving top board (10) erects with pedal (15), when rack beam (16) was in the position of kerve lower end (24), ladder closed up fully; When rack beam (16) is stuck in kerve bayonet socket (25) when locating, ladder is opened fully.
The present invention can will control in wheel (4) and chain (5) wrap in chain box, arrive control wheel (4) and the chain (5) of rotation to avoid Body contact, play the certain protection effect.
