Description

[Technical field]

[0001] The invention relates to the field of conveyor line loading, in particular to a height-adjustable loading vehicle applicable to a two-layer conveyor line. [Background Technology]

[0002] At present, in the automated assembly industry, a double-layer conveyor line is often used to convey raw materials to the assembly station, with the upper layer conveying raw materials and the lower layer collecting empty trays. When placing trays containing raw materials on the upper conveyor line, a hand-pushed hydraulic car is generally used. The worker places the tray containing raw materials on the hand-pushed hydraulic car, raises the hydraulic car to the height of the upper conveyor line, and then pushes the tray containing raw materials to the upper conveyor line. After the raw materials of the tray are assembled, the empty tray is transported out through the lower conveyor line. At this time, the worker needs to take away the empty tray and lower the hydraulic car to the height of the lower conveyor line. In this way, the worker has to repeatedly adjust the height of the hydraulic car. Every time the height is docked with the upper or lower conveyor line, the worker needs to carefully adjust it, which not only increases the worker's working time, but also speeds up the consumption of the service life of the hydraulic car. [Summary of the invention]

[0003] The purpose of the present invention is to solve the above-mentioned shortcomings and provide a loading cart that is applicable to two-layer conveyor lines and has adjustable height. Workers only need to align the loading cart with the upper and lower conveyor lines for the first time, which saves workers' labor time, replaces hydraulic carts, and saves costs and time.

[0004] In order to achieve the above purpose, a height-adjustable loading vehicle suitable for a two-layer conveyor line is designed, comprising a frame 1, a lower layer fixing block 2, a lower layer adjusting rod 3, a lower layer plate 4, an unpowered roller assembly 5, an upper layer fixing block 6, an upper layer adjusting rod 7 and an upper layer plate 8. The lower layer plate 4 and the upper layer plate 8 are respectively provided on the lower layer and the upper layer of the frame 1.

Unpowered roller assemblies 5 are arranged on the lower plate 4 and the upper plate 8. A material tray 5.4 is arranged on the roller 5.6 of the unpowered roller assembly 5. The roller 5.6 on the upper plate 8 and the lower plate 4 moves up and down respectively by the upper adjusting rod 7 and the lower adjusting rod 3, thereby completing the docking with the upper and lower conveyor lines of the automatic assembly line.

[0005] Furthermore, the unpowered roller assembly 5 is positioned with the lower plate 4 and the upper plate 8 by means of pin holes and connected by screw locking, which not only ensures reliable connection but also further saves operation time.

[0006] Furthermore, the unpowered roller assembly 5 includes a roller fixing plate 5.1, a roller pressure plate 5.2, a guardrail 5.5 and a roller 5.6. The rollers 5.6 are arranged side by side, and both ends of the rollers 5.6 are locked to the roller fixing plate 5.1 through the roller pressure plate 5.2. A material tray 5.4 is placed on the roller 5.6. Guardrails 5.5 are provided on the left and right sides of the material tray 5.4. The guardrails 5.5 are inserted into the fixing holes of the roller fixing plate 5.1, thereby ensuring that the material tray 5.4 will not slip out of the material cart during transportation.

[0007] Furthermore, both ends of the roller 5.6 are respectively placed in the grooves of the roller fixing plate 5.1, and the roller pressure plate 5.2 is fixed on the roller fixing plate 5.1 by means of pin hole positioning and screw locking. This structural design is simple and reliable, saving on-site operation time.

[0008] Furthermore, the unpowered roller assembly 5 also includes a side guide wheel 5.3, which is distributed along the feeding direction of the roller 5.6, and is arranged on the outside of the guardrail 5.5 and is rollingly connected to the guardrail 5.5. The side guide wheel 5.3 is fixed to the roller fixing plate 5.1 by threaded locking.

[0009] Furthermore, the unpowered roller assembly 5 located on the upper plate 8 moves up and down by adjusting the upper adjusting rod 7, so that the upper surface of the roller 5.6 on the upper plate 8 is the same height as the upper conveying line of the automatic assembly line; the unpowered roller assembly 5 located on the lower plate 4 moves up and down by adjusting the lower adjusting rod 3, so that the upper surface of the roller 5.6 on the lower plate 4 is the same height as the lower conveying line of the automatic assembly line.

[0010] Furthermore, the lower fixed block 2 is connected to the lower layer of the frame 1 through screw holes, the bottom end of the lower adjusting rod 3 is fixedly connected to the lower fixed block 2, the lower adjusting rod 3 is distributed at the four corners of the lower plate 4, the upper fixed block 6 is connected to the upper layer of the frame 1 through screw holes, the bottom end of the upper adjusting rod 7 is fixedly connected to the upper fixed block 6, and the upper adjusting rod 7 is distributed at the four corners of the upper plate 8.

[0011] Compared with the prior art, the present invention provides a loading trolley which is applicable to two-layer conveyor lines and has adjustable height. Workers only need to align the loading trolley with the upper and lower conveyor lines respectively for the first time. The upper layer of the loading trolley is used to place trays containing raw materials, and the lower layer is used to collect empty trays. The loading trolley has a novel structure, a reasonable design, is simple and reliable, saves workers' working time, replaces the hydraulic trolley, and indirectly saves costs and time for the company. It is worthy of popularization and application. [Drawings]
