Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a pneumatic elevator. Background Art

[0002] Elevators are devices that transport goods by changing potential energy. Since the advent of industrial automation, many automated production steps require the use of lifting mechanisms. In automated production lines, elevators are important equipment that connects two processes, completing the transportation and lifting of goods during the production process.

[0003] In the field of logistics sorting, a device is needed in the box-type package intelligent material line that can communicate and provide transportation between the upper and lower levels, so that the box-type package intelligent material line can make full use of the factory space to achieve multi-functional needs. For example, the upper-level equipment can transport goods for sorting, and the lower-level equipment can be used for turnover boxes, carton recycling and other intelligent needs. Currently, there are only motor-type lifting drive devices on the market, which require corresponding control accessories such as electrical cabinets. The cost is relatively high and the space is large. There is a special need for a box-type lift with a compact structure, simple movement and easy maintenance.

[0004] To solve the above problems, Chinese patent application number 202322843546.0 discloses a high-load pneumatic lift. The pneumatic lift disclosed above includes: a column assembly; a lifting assembly, the lifting assembly is configured to move along the vertical direction of the column assembly; a driving mechanism; a driving wheel, the driving mechanism drives the driving wheel to move along the vertical direction of the column assembly; a driven wheel, a driven wheel is provided on each side of the driving wheel, and the two driven wheels are connected to the lifting assembly; a transmission belt, the two ends of the transmission belt are respectively fixedly connected to the upper part of both sides of the column assembly, and the transmission belt passes through a driven wheel, a driving wheel, and another driven wheel in sequence.

The support frame 1 is provided with a cylinder 203 that drives the lifting frame 201 and the lifting platform 202 to rise and fall synchronously; the lifting platform 202 is provided with a conveying mechanism 3 for conveying goods, and the conveying mechanism 3 includes a plurality of conveying rollers 302 that operate synchronously.

[0027] Furthermore, the support frame 1 is a gantry structure. Specifically, the support frame 1 is composed of two parallel columns and a crossbeam. The crossbeam is connected to the top of the two columns to fix the two columns. The lifting frame 201 of the lifting mechanism 2 is slidably connected to the two columns. A cylinder 203 is set between the two columns. The cylinder 203 is set along the height direction of the column. The output end of the cylinder is connected to the lifting frame 201. The lifting mechanism 2 is driven by the cylinder 203 to lift and lower. It is lifted and lowered directly by the cylinder 203, and there is no need to drive the lifting mechanism 2 to lift and lower through a transmission belt, thereby ensuring that the lifting mechanism 2 will not shake during the lifting process, improving the stability of the goods during the lifting process, and avoiding the situation where the goods move and fall.

[0028] In addition, the lifting platform 202 is set horizontally, and a conveying mechanism 3 is set on the lifting platform 202. Under the action of several conveying rollers 302 of the conveying mechanism 3, the goods are driven to move horizontally, thereby realizing the transportation of the goods and improving the efficiency of the goods transportation.

[0029] The support frame 1 is provided with a slide rail 102 arranged along the height direction of the support frame 1, and the lifting frame 201 is provided with a slider 2011 slidably connected to the slide rail 102. Furthermore, the slide rail 102 is arranged on two columns, and the two slide rails 102 are arranged along the height direction of the columns. At the same time, the two slide rails 102 are located on the same side of the two columns. Slide blocks 2011 are provided on both sides of the lifting frame 201, and there are two sliders 2011 on each side, and they are distributed along the height direction of the lifting frame 201. The sliders 2011 are slidably connected to the corresponding slide rails 102. The lifting frame 201 is lifted and lowered on the support frame 1 through the connection between the slide rails 102 and the sliders 2011, which ensures that the lifting mechanism 2 does not shake during the lifting process, thereby improving the stability of the lifting mechanism 2 during the lifting process.

Furthermore, the bottom end of the cylinder 203 is installed on the mounting seat 103, and the connecting piece 2012 is set in the direction of the support frame 1. The output shaft of the cylinder 203 is connected to the connecting piece 2012. The extension and retraction of the output shaft is controlled by the cylinder 203, thereby realizing the lifting and lowering of the lifting mechanism 2.

[0031] The lifting platform 202 is connected to the bottom end of the lifting frame 201, and a base 101 is provided at the bottom end of the support frame 1 for providing support for the lifting platform 202. Furthermore, the lifting platform is horizontally fixedly installed at the bottom of the lifting frame 201, and the base 101 is fixedly set at the bottom of the support frame 1. The bottom end of the base 101 is in contact with the ground, and the top is connected to the lifting platform 202. Specifically, when the cylinder 203 controls the lifting mechanism 2 to descend to the lowest point, the lifting platform 202 is in contact with the base 101, and the support function of the lifting platform 202 is achieved through the base 101.

[0032] The ends of the conveying rollers 302 are provided with pulleys 3021, and the pulleys 3021 are all located at the same end of the conveying rollers 302. Furthermore, the pulleys 3021 are fixedly arranged at the ends of the conveying rollers 302, and the pulleys 3021 on each conveying roller 302 are all located at the same end.

[0033] In addition, a synchronous belt 3022 is connected between two adjacent pulleys 3021 to drive the multiple conveying rollers 302 to rotate synchronously. The multiple synchronous belts 3022 drive the multiple conveying rollers 302 to rotate synchronously, thereby realizing horizontal transportation of goods.

[0034] The end of one of the conveyor rollers 302 is connected to a drive motor 304 that drives several conveyor rollers 302 to operate synchronously. The drive motor 304 and the pulley 3021 are located at opposite ends of the conveyor roller 302. Furthermore, the output end of the drive motor 304 is connected to the conveyor roller 302, and the drive motor 304 is only connected to one conveyor roller 302. By driving the conveyor roller 302 to rotate, all the conveyor rollers 302 are driven to operate synchronously under the action of the synchronous belt 3022.

[0035] The conveying mechanism 3 also includes a mounting frame 301 for mounting a plurality of conveying rollers 302, and a drive motor 304 is arranged on the mounting frame 301. Furthermore, the mounting frame 301 is fixedly set on the lifting platform 202, and the plurality of conveying rollers 302 are rotatably connected to the mounting frame 301.
