Description

Technical Field

[0001] The invention relates to supporting facilities of a rail logistics transmission system, in particular to a logistics rail sweeper. 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 powder and solid debris generated by the friction between the electric carbon brush and the power supply copper rail, and the meshing between 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. Summary of the invention

[0006] In view of the deficiencies in the prior art, the technical problem to be solved by the present invention is to propose a track logistics sweeper for automatically cleaning dirt on grooved tracks.

[0007] The rail logistics sweeper capable of solving the above technical problems comprises a travel unit, a sweeping unit, an electric control unit and an onboard unit, wherein:

[0008] 1. The walking unit includes left and right non-powered wheels which are arranged at the front and rear of the bottom of the frame and correspond to the walking rail surfaces on both sides of the groove track bottom respectively. A climbing gear and a power rubber wheel which are coaxially arranged at the bottom of the frame are arranged between the left and right non-powered wheels at the rear. The climbing gear is arranged on one side of the middle part of the groove track bottom, and the power rubber wheel corresponds to the walking rail surface on the same side of the gear rail.

[0009] 2. The vehicle-mounted unit comprises a carriage arranged on a vehicle frame, the carriage is provided with heat dissipation holes, and an exhaust fan is arranged in the carriage.

[0011] 4. The cleaning unit includes a dust suction mechanism and a cleaning mechanism which are arranged at the bottom of the frame in front of and behind a plurality of power supply copper rails.

[0012] ①. One structure of the dust suction mechanism includes a DC-powered vacuum cleaner, a dust suction pipe joint and a silicone hose. 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 arranged in the vehicle compartment through a dust suction pipe. The left and right side-by-side air inlets at the bottom of the dust suction pipe joint are correspondingly connected to the silicone hose hanging downward.

[0013] ②. One structure of the cleaning mechanism includes left and right horizontally mounted rotary dust removal brushes on a cleaning frame, the left and right ends of the cleaning frame are provided with wheel frames corresponding to the rail bottoms on both sides of the groove track, the cleaning frame is installed on the bottom of the frame through left and right guide compression spring assemblies, the spring forces of the left and right guide compression spring assemblies act on the cleaning frame to press the walking wheel groups on the left and right wheel frames against the rail bottom, the cleaning frame is provided with a cleaning motor with a reducer, and the reducer of the cleaning motor is connected to the rotary dust removal brush through a pulley transmission pair.

[0014] 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.

[0015] In order to further expand the dust collection range, two air inlets are added to the bottom of the dust collection pipe joint and connected to a hanging silicone hose, and the two silicone hoses are respectively located at the bottom of the two sides of the groove track.

[0016] In a preferred embodiment, the dust suction mechanism and the cleaning mechanism are arranged between the front and rear wheels.

[0017] To ensure safety, the front and rear ends of the frame are both provided with anti-collision devices.

[0018] Beneficial effects of the present invention:

[0019] The rail logistics sweeper of the present invention is suitable for cleaning dirt on the groove track of the rail logistics transmission system. The sweeper repeatedly travels in the groove track, removes oil, floating dust and solid debris in the groove track through a rotating dust removal brush and sucks the dirt out of the groove track through a vacuum cleaner, thereby automatically completing the internal cleaning of the groove track with high working efficiency.
