Referring to fig. 1-4, a lifting platform suitable for a construction site comprises a fixed rod 1, a platform 2, a driving mechanism 3, a plurality of connecting pieces 4 and a supporting plate 5.
As shown in fig. 1 and 4, the bottom of the fixing rod 1 is provided with a supporting plate 5, four corners of the supporting plate 5 are provided with fixing holes 5a, and the fixing rod is fixed on the ground by means of bolts and screws; the side wall of the fixed rod 1 is provided with a plurality of connecting pieces 4, and the connecting pieces 4 are connected with the scaffold, so that the support rod is fixed on the scaffold.
Specifically, as shown in fig. 1 and 3, the connecting piece 4 in the present embodiment is fixed on the cross bar of the scaffold, and because of the difference in height between the cross bars of different scaffolds, in order to make the fixing rod 1 have better versatility for connecting the scaffold through the connecting piece 4, the fixing rod 1 is provided with a plurality of first sliding grooves 1a along the height direction, and one ends of the plurality of connecting pieces 4 are slidably disposed in the first sliding grooves 1 a.
In this embodiment, the connection manner of the connecting piece 4 and the first chute 1a may be: one end of the connecting piece 4 is provided with a sliding block, and the sliding block is clamped into the first sliding groove 1a to realize sliding connection; it should be noted that the connecting piece 4 and the first chute 1a may be slidably connected by other means, which is not limited in this embodiment.
In this embodiment, the structure of the connecting piece 4 is a C-shaped hoop structure, as shown in fig. 2, one end of the connecting piece is provided with an opening, the inner wall of the connecting piece 4 is attached to the scaffold, and the opening is provided with a bolt, so that the connecting piece 4 is firmly fixed on the scaffold by tightening the bolt.
As shown in fig. 1, the platform 2 is located at one side of the fixed rod 1, and the driving mechanism 3 is used for driving the platform 2 to move along the height direction; specifically, the driving mechanism 3 includes a housing 31, a rack 32, a gear 33, a worm 34, and a motor 35; the shell 31 is arranged on the fixed rod 1 in a sliding manner along the height direction, and the top of the shell is connected with the platform 2; the rack 32 is arranged on the side wall of the fixed rod 1 along the height direction, and the gear 33 is rotatably arranged in the shell 31 and meshed with the rack 32; one end of the worm 34 is rotatably connected to the housing 31, the other end is connected to an output shaft of the motor 35, and the worm 34 is meshed with the gear 33. When transporting the article, the workman puts the article on platform 2, and motor 35 starts for worm 34 rotates, and worm 34 makes gear 33 rotate, and gear 33 and rack 32 meshing, thereby makes casing 31 drive platform 2 along the direction of height and reciprocates, plays the effect of transporting the article.
It should be noted that, because the driving mechanism 3 adopts the transmission mode of the worm 34 and the gear 33, the gear 33 can be driven to rotate by using the worm 34, and the gear 33 cannot drive the worm 34 to rotate, so that the shell 31 can complete self-locking and cannot fall under the action of gravity.
It should be noted that, because the existence of the connecting piece 4 can limit the movement of the housing 31 on the fixing rod 1, a gap which completely penetrates along the height direction is arranged on the housing 31, and when the housing 31 slides on the fixing rod 1, the connecting piece 4 penetrates through the gap of the housing 31, so that the sliding of the housing 31 is not affected; meanwhile, in order to make the width of the gap smaller, the shell 31 has a larger contact area with the fixed rod 1, and the axis of the connecting piece 4 is horizontal to the ground; if the axis of the connector 4 is perpendicular to the ground, the gap requires a large width to allow the connector 4 to pass through the gap, which is disadvantageous in that the housing 31 is mounted on the fixing bar 1, which is why the connector 4 is fixed on the rail of the scaffold in this embodiment.
Further, as shown in fig. 1 and 2, two opposite sides of the fixing rod 1 along the height direction are respectively provided with a second chute 1b, the inner side wall of the shell 31 is provided with two protrusions 311, when the shell 31 is installed on the fixing rod 1, the protrusions 311 are clamped into the second chute 1b, and the fixing rod has a transverse limiting function, so that the shell 31 is prevented from falling off from the fixing rod 1; in this embodiment, the protrusion 311 is preferably a pulley, and when the housing 31 moves on the fixing rod 1, the friction force can be reduced by using the pulley, so that the movement is smoother.
The above is only a preferred embodiment of the present utility model, and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
