Description

Technical Field

[0001] The utility model relates to the field of logistics equipment, in particular to a double-cargo-platform independently moving material box elevator. Background Art

[0002] The material box elevator is a kind of automated logistics equipment. Currently, a material box elevator in the industry has only one cargo platform. From the structural point of view, the cargo platform currently has single-station and multi-station. Multi-station can usually be arranged horizontally or vertically, but there is only one lifting action. When docking multiple conveying stations, inefficiency will occur.

[0003] Even if the number of workstations can be increased by adding material box elevators, multiple devices not only take up more space, but the efficiency improvement is still affected by software scheduling or order type. It is still necessary to change layers to make the transportation of multiple workstations efficient. Such layer changing actions will affect the efficiency of the elevator. Utility Model Content

[0011] Furthermore, the lower stopper is fixed at the lower part of the column and can trigger the limit switch on the unloading platform; the upper stopper is fixed at the top of the column and can trigger the limit switch on the upper loading platform.

[0023] The technical solution of the utility model is further explained below in conjunction with the accompanying drawings.

[0024] like Figure 1 As shown, a double cargo platform independent motion type material box elevator 1 includes a chassis component 2, a column component 3, a lower cargo platform 4 and an upper cargo platform 5, the chassis component 2 provides power for the lower cargo platform 4 and the upper cargo platform 5 to move up and down, the column component 3 is fixed on the chassis component 2, and provides guide rails and support for the lower cargo platform 4 and the upper cargo platform 5; the lower cargo platform 4 and the upper cargo platform 5 move independently on the column component 3 respectively, and the upper cargo platform 4 runs above the projection of the lower cargo platform 5.

[0025] like Figure 2 As shown, the chassis component 2 includes: a chassis frame 201, a right synchronous pulley 203, a right lifting motor 204, a right synchronous belt 205, a left lifting motor 207, a left synchronous belt 208, a left synchronous pulley 206, an upper driven wheel 210, an upper fixed seat 211, an upper driven wheel 212, and an upper fixed seat 213; the chassis frame 201 mainly plays the role of connecting, fixing and supporting, on which the right hoist motor 204, the right synchronous pulley 205, the left lifting motor 207, and the left synchronous pulley 206 are fixed; the upper left fixed seat 213 and the upper left driven wheel 212, the upper right fixed seat 211 and the upper right driven wheel 210 are located above the column component 3; the right synchronous belt 205 is connected to the unloading platform 4, the left synchronous belt 208 is connected to the upper loading platform 5, the right hoist motor 204 drives the right synchronous belt 205, and the left lifting motor 207 drives the left synchronous pulley 206. The lower buffer 202 is fixed on the bottom frame 201, facing the bottom of the unloading platform 4, and mainly plays the role of buffering the impact force caused by the unloading platform 4 falling; the lower laser rangefinder 209 is fixed on the bottom frame 201 or the ground.

[0026] like Figure 3 As shown, the column component 3 includes a lower block 301, a column 302, a right drag chain 303, a left drag chain 304, and an upper block 305. An upper buffer 307 is fixed on the top of the column 302, facing the top of the upper cargo platform 5; an upper laser rangefinder 306 is fixed on the top of the column 302. A right drag chain 303 and a left drag chain 304 are fixed on the column 302. The right drag chain 303 is mainly used to provide power for the electrical components on the lower cargo platform 4, and the left drag chain 304 provides power for the electrical components on the upper cargo platform 5. The lower block 301 is fixed at the lower part of the column 302, and can trigger the limit switch on the lower cargo platform 4 to prevent the right lifting motor 207 from losing control and causing the cargo platform 4 to fall; the upper block 305 is fixed at the top of the column 302, and can trigger the limit switch on the upper cargo platform 5 to prevent the left lifting motor 207 from losing control and causing the cargo platform 5 to hit the top.

Two side guide wheels 406 and one positive guide wheel 407 are set as a group, and a total of four groups are fixed on the cargo platform frame 401 respectively. The four groups of guide wheels use the column 302 as a guide rail to ensure that the cargo platform will not tilt during operation. The synchronous belt fixing plate 403 is fixed on the cargo platform frame 401 and is connected to the synchronous belt 205 at the same time, so that the synchronous belt 205 can drive the cargo platform 4 to move up and down. The conveyor 404 plays the role of transporting goods on the cargo platform 4, and the drag chain 303 is responsible for its power supply and signal transmission. The laser reflector 402 is set below the cargo platform to facilitate the laser rangefinder 209 to read the height information of the cargo platform 4.

When the limit switch 405 is triggered by the lower stop block 301, the lifting motor 204 stops suddenly to prevent collision.

[0028] like Figure 5 As shown, the operation principle and basic structure of the cargo platform 5 are the same as those of the cargo platform 4, except that the laser reflector 501 is located at the side and rear of the cargo platform 5, so as to facilitate the reading of the height value by the upper laser rangefinder 306. A polyurethane buffer 502 is arranged under the cargo platform to prevent the cargo platform 4 and the cargo platform 5 from colliding and reduce the collision impact.
