Description

Technical Field

[0001] The invention relates to a supporting device for a rail logistics transmission system, in particular to a rail logistics cleaning unit. Background Art

[0002] The rail logistics transmission system is a system that uses intelligent cargo-carrying carts to transport items on a dedicated grooved track under computer control.

[0003] The intelligent cargo trolley relies on the front and rear sets of left and right running wheels to walk on the bottom surfaces of both sides of the horizontal groove track, and relies on the climbing gears between the rear set of running wheels to engage with the rail bottom gears of the curved groove track or the vertical groove track to achieve climbing and lifting. During operation, the three power-receiving carbon brushes at the bottom of the intelligent cargo trolley and the three power-supply copper rails at the bottom of the groove track are always in contact with each other to realize the power transmission between the logistics track transmission system and the intelligent cargo trolley.

[0004] During the long-term operation of the rail logistics transmission system, dust and fine particles in the air will accumulate in the grooved track. The metal dust and solid debris generated by the friction between the electric carbon brush and the power supply copper rail, and the meshing of the climbing gear and the rack rail will be scattered in the grooved track. In order to ensure the normal operation of the rail logistics transmission system, the rail logistics transmission system must be shut down regularly to clean the oil, floating dust and solid debris in the grooved track.

[0005] However, the grooved track used in the rail logistics transmission system is different from the conventional convex track. The existing conventional convex track cleaning device cannot adapt to the cleaning application of the grooved track. The grooved track can only be cleaned manually, resulting in a large amount of manpower waste and time delay, which seriously affects the operating efficiency of the rail logistics transmission system.

[0006] In order to address the deficiencies of the prior art, the applicant company has proposed a "Railway Logistics Sweeper", whose technical solution includes a traveling unit, a cleaning unit, an electronic control unit and a vehicle-mounted unit, wherein the traveling unit includes left and right wheels arranged at the front and rear of the bottom of the frame, and a climbing gear and an active rubber wheel arranged at the bottom of the frame are arranged between the left and right wheels at the rear; the vehicle-mounted unit includes a carriage arranged on the frame, the carriage is provided with heat dissipation holes, and an exhaust fan is arranged in the carriage; the electronic control unit is arranged in the carriage, including a main board, a driver, a battery and auxiliary electrical components connected by circuits, and a plurality of power-receiving brushes connected to the electronic control unit by lines are arranged at intervals on the left and right sides of the bottom of the frame; the cleaning unit includes a dust suction mechanism and a cleaning mechanism arranged at the front and rear of the bottom of the frame corresponding to a plurality of power supply copper rails. Summary of the invention

[0007] The purpose of this invention is to provide patent protection for the rail logistics cleaning unit in the "Rail Logistics Cleaning Vehicle".

[0008] The rail logistics cleaning unit of the present invention has a technical solution comprising a dust suction mechanism and a cleaning mechanism arranged at the front and rear of the bottom of the frame of the cleaning vehicle, wherein:

[0009] 1. The dust suction mechanism comprises a DC-powered vacuum cleaner, a dust suction pipe joint and a silicone hose. The DC-powered vacuum cleaner is arranged in a compartment on the frame. The dust suction pipe joint is installed at the bottom of the frame through an up and down adjustable structure. The top air outlet of the dust suction pipe joint is connected to the air suction port of the DC-powered vacuum cleaner through a dust suction pipe. The bottom of the dust suction pipe joint is provided with air inlets arranged side by side in the left and right directions, and each air inlet is connected to a silicone hose hanging downward.

[0010] 2. The cleaning mechanism includes a rotating dust removal brush installed on the cleaning frame on the left and right sides. Wheel frames are provided at the left and right ends of the cleaning frame. The cleaning frame is installed on the bottom of the frame through left and right guide compression spring assemblies. The spring force of the left and right guide compression spring assemblies acts on the cleaning frame to press the walking wheel groups on the left and right wheel frames onto the track surface on which the left and right unpowered wheels of the cleaning vehicle travel. A cleaning motor with a reducer is provided on the cleaning frame. The reducer of the cleaning motor is connected to the rotating dust removal brush through a pulley transmission pair.

[0011] Conventionally, the cleaning range of the rotary dust removal brush and the dust suction range of the silicone hose both correspond to the copper rail seat on which three power supply copper rails are installed.

[0012] In order to further expand the dust collection range, two air inlets on the left and right are added to the bottom of the dust collection pipe joint and connected to hanging silicone hoses, and the two silicone hoses are respectively located on the left and right rail surfaces where the wheels travel.

[0013] Beneficial effects of the present invention:

[0014] The cleaning vehicle equipped with the rail logistics cleaning unit of the present invention is suitable for cleaning dirt on the groove track of the rail logistics transmission system. The cleaning vehicle repeatedly moves in the groove track, removes oil, floating dust and solid debris in the groove track through the rotating dust removal brush of the cleaning mechanism, and sucks the dirt out of the groove track through the silicone hose of the dust suction mechanism, thereby automatically completing the internal cleaning of the groove track with high working efficiency.
