Detailed description of the invention
As shown in Figures 1 to 3, a kind of lifting mechanism, comprises erecting frame 1, sloping desk 2, pushing mechanism 3, lifting plate 4, lifting table 5.Described sloping desk 2 and described erecting frame 1 sliding block joint, sloping desk 2 can the plane above erecting frame 1 carry out horizontal direction horizontally slips.Pushing mechanism 3 is fixed on erecting frame 1, and sloping desk 2 is specifically as follows straight line cylinder driver train or the mechanism such as rack-and-gear, screw mandrel with described pushing mechanism 3() drive and be connected, pushing mechanism 3 promotes the movement that sloping desk 2 carries out in horizontal direction.Lifting plate 4 is fixedly connected with lifting table 5, lifting plate 4 and sloping desk 2 sliding block joint, when sloping desk 2 carries out horizontal motion, lifting plate 4 is in the enterprising line slip in the inclined-plane of sloping desk 2, because there is different height the position of sliding, so lifting plate 4 can be elevated along with the parallel motion of sloping desk 2, thus lifting table 5 is elevated.Lifting mechanism, by horizontal motion is converted to vertical motion, saves the installing space on driver train vertical direction, solves the technical barrier making the driver train allowing level install provide stable perpendicular movement.Further, because sloping desk 2 bevel angle with lifting plate 4 sliding block joint can be arranged according to the relation of lifting force and horizontal thrust, therefore when horizontal thrust is less, a larger lifting force can be provided by reduction bevel angle.
Preferably, as shown in Figure 3, sloping desk 2 is provided with surface groove 21, described lifting plate 4 is provided with sliding wheel 41.Surface groove 21 and sliding wheel 41 are slidingly fitted, and because surface groove 21 surrounds sliding wheel 41, when lifting table 5 rises, the bottom surface inside dependence surface groove 21 and the contact of sliding wheel 41 provide hoisting force upwards; When lifting table 5 declines, itself gravity can be relied on to decline, and rely on the upper surface of inner side of surface groove 21 and the contact of sliding wheel 41 to provide downforce when declining and being obstructed.So, lifting mechanism is made can be arranged on the occasion of different demand flexibly.
Preferably, sloping desk 2 movement in the horizontal direction has end position; Described end position is provided with energy disperser 6, to limit the shift motion in described sloping desk 2 horizontal direction.When sloping desk 2 moves to end position, energy disperser 6 props up sloping desk 2 and cushions it, prevents it from causing impact to pushing mechanism 3 because force of inertia continues motion, improves the safety of lifting mechanism.
Preferably, sloping desk 2 is provided with plain bearing 22, sloping desk 2 by plain bearing 22 and erecting frame 1 moving contact, to reduce sloping desk 2 and erecting frame 1 friction force when relative movement.Erecting frame 1 is being provided with bearing plate 11, with the mobile route of specification sloping desk 2 along the moving direction of described plain bearing 22.The shape of cross section of bearing plate 11 is inverted L-shaped (as shown in Figure 4), can limit plain bearing 22 in the vertical direction, if when plain bearing 22 provides downforce downwards, the bearing plate 11 of inverted L-shaped can prevent plain bearing 22 from tilting, thus increase the stability of lifting mechanism.
Preferably, erecting frame 1 is provided with guidepost 12, lifting table 5 is arranged the pilot hole 51 matched with described guidepost 12.Lifting table 5 bear unbalanced gravity carry out dipping and heaving time, can keep move stability.
Preferably, lifting plate 4 is also provided with auxiliary hole 42, while ensureing its Joint strenght, alleviates the weight of lifting mechanism entirety.。
Preferably, surface groove 21 is α with the angle of horizontal surface, and described angle α is 30 ° to 45 °.When angle α is 30 °, described lifting force is exactly cot30 ° times namely 1.73 times of pushing mechanism 3 propelling thrust, enhance lifting force, but the stroke of horizontal displacement is also 1.73 times of lifting travel, if need larger lifting force can arrange less angle; If need larger stroke can arrange larger angle.When angle α is 45 °, lifting force is equal with propelling thrust, and horizontal throw is equal with lifting travel.
Such scheme makes the structure of lifting mechanism more stable, reaches again convenient installation, is suitable for different lifting force requirements and the technique effect of range demands occasion.
The above embodiment only have expressed comparatively concrete embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
