DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] Example 1

[0025] See also Figure 1-Figure 5 A prefabricated stair lifting and stacking device comprises a base plate 101, a stacking mechanism 200 for separately stacking multiple layers of prefabricated stairs is fixedly connected to the left side of the top surface of the base plate 101, a lifting mechanism 300 fixedly connected to the top surface of the base plate 101 is provided on the right side of the stacking mechanism 200, and the lifting mechanism 300 is used to transport the prefabricated stairs at different heights.

[0026] See also Figure 2 The stacking mechanism 200 includes columns 201 fixedly connected to the four left corners of the top surface of the base plate 101, and a plurality of equidistantly arranged cross bars 202 are fixedly connected between two of the columns 201. The arrangement of the cross bars 202 is used to achieve layered placement. The top surfaces of the two cross bars 202 at the same height are fixedly connected to the two ends of the bottom surface of the transmission belt 203, and the transmission belt 203 is used to transport and stack the prefabricated stairs.

[0027] See also Figure 3-Figure 5 The lifting mechanism 300 includes an adjusting box 301 fixedly connected to the four right corners of the top surface of the bottom plate 101, and threaded rods 302 are provided in the two adjusting boxes 301 on the left side. The upper ends of the threaded rods 302 penetrate into the installation box 307 and are fixedly connected to the driving assembly. Under the action of the driving assembly, the threaded rods 302 rotate, and the bottom surface of the installation box 307 is fixedly connected to the top surfaces of the two adjusting boxes 301. Guide rods 303 are provided in the two adjusting boxes 301 on the right side. The setting of the guide rods 303 makes the movement of the conveying platform 306 more stable. The two threaded rods 302 are threadedly connected to a group of movable sleeves 304, and the two guide rods 303 are slidably connected to another group of movable sleeves 304. A connecting rod 305 is fixedly connected between the same group of movable sleeves 304. The movable sleeve 304 drives the connecting rod 305 to move, thereby driving the conveying platform 306 to be lifted and lowered. The top surfaces of the two connecting rods 305 are fixedly connected to the two ends of the bottom surface of the conveying platform 306.

[0028] See also Figure 4-Figure 5The driving assembly includes a sprocket 309, the upper end of the threaded rod 302 penetrates into the chain 308 and is fixedly connected to the sprocket 309, and the two sprockets 309 are connected by the chain 308. The top end of one of the threaded rods 302 penetrates and extends out of the installation box 307 and is fixedly connected to the output end of the motor. The motor is started, and the motor drives one of the threaded rods 302 to rotate, thereby rotating the sprocket 309 fixedly connected thereto. Under the transmission action of the chain 308, the other sprocket 309 rotates and drives the other threaded rod 302 to rotate.

[0029] Example 2

[0030] The difference from Example 1 is that:

[0031] See also Figure 2 The two leftmost columns 201 are fixedly connected with extension rods 204, and the extension rods 204 are fixedly connected with control switches 205. The control switch 205 is used to control whether the transmission belt 203 and the conveying platform 306 continue to convey. Each set of the extension rods 204 and the control switches 205 are arranged above the transmission belt 203.

[0032] See also Figure 1-Figure 2 The bottom surface of the cross bar 202 is provided with reinforcing ribs, and the two ends of the reinforcing ribs are fixedly connected to the column 201 and the cross bar 202, thereby increasing the stability of the stacking mechanism 200 in the device.

[0033] See also Figure 5 Bearings are provided at both ends of the threaded rod 302. The provision of the bearings makes the rotation of the threaded rod 302 more stable.

[0034] See also Figure 1 A group of staggered oblique support rods are provided on both sides of each transmission belt 203, and both ends of the oblique support rods are fixedly connected to the columns 201 to support and shield the front and rear sides of the prefabricated stairs placed on the transmission belt 203, thereby increasing the stability and safety of the placement.

[0035] Working principle: the prefabricated stairs to be stacked are placed on the conveyor platform 306, and then the motor is started, the threaded rod 302 rotates, and under the limiting action of the guide rod 303, the movable sleeve 304 drives the connecting rod 305 to move upward, thereby driving the conveyor platform 306 to change its height, so that the conveyor platform 306 is first aligned with the transmission belt 203 of the first layer, and the conveyor platform 306 and the transmission belt 203 are started to transfer the prefabricated stairs from the conveyor platform 306 to the transmission belt 203. When its front end touches the control switch 205, the transmission is stopped. After completing one conveying and stacking, the motor is started again to make the conveyor platform 306 return to the initial position, and the second prefabricated stairs to be stacked are placed on the conveyor platform 306. The above steps are repeated to make the conveyor platform 306 and the second layer The transmission belt 203 is at the same height to achieve stacking of the second layer, and the stacking of the third, fourth, and fifth layers is achieved by analogy. The equipment is convenient for stacking, saves manpower, and improves work efficiency.
