Description

Technical Field

[0001] The invention relates to the technical field of track snow-clearing and ice-removing vehicles, in particular to an automatic track snow-clearing and ice-removing vehicle. Background Art

[0002] Rail transit refers to a type of transportation vehicle or transportation system that requires operating vehicles to travel on specific tracks. After entering the autumn and winter seasons, there is more rain and snow, and ice and snow will cover the tracks in rain and snow. In order to ensure the normal passage of vehicles and avoid accidents, the ice and snow on the tracks must be cleared in time. At present, the removal of ice and snow is basically done manually or by spraying deicing agents. The manual method is inefficient, costly, and has safety hazards. Deicing agents pollute the environment and cause erosion to the tracks.

[0003] The Chinese patent application number: CN2009202896 discloses a track snow removal and ice breaking vehicle, which can remove snow on the track, and can also use an ice breaking mechanism to break ice on the track surface, and then use an ice shoveling mechanism to clean up the broken ice on the track.

[0008] Furthermore, the vehicle body structure includes a frame, a driving wheel and a control compartment, a power battery is arranged inside the control compartment, the high-pressure gas source is fixedly installed inside the control compartment, the driving wheel is arranged at the bottom of the frame, the driving wheel is an electric wheel, and the driving wheel is electrically connected to the power battery.

[0009] Furthermore, adjacent mounting seats are fixedly connected via reinforcing ribs.

[0010] Furthermore, the adjusting mechanism includes an adjusting rod, a limiting sleeve and a lifting column, the top of the adjusting rod is rotatably connected to the connecting frame and passes through the upper surface of the connecting frame, and two baffles distributed up and down are fixedly connected to the top outer wall of the adjusting rod, and the two baffles respectively abut against the upper and lower surfaces of the connecting frame; the side wall of the limiting sleeve is fixedly connected to a connecting plate, and the top of the connecting plate is fixedly connected to the bottom of the connecting frame; the bottom end of the lifting column is fixedly connected to the mounting frame, and the top is slidably connected to the inside of the limiting sleeve, the bottom of the adjusting rod extends to the inside of the limiting sleeve and is threadedly connected to the lifting column, a limiting groove is provided on the outer wall of the limiting sleeve, and a limiting block matching the limiting groove is fixedly connected to the outer wall of the lifting column, and the limiting block is slidably connected in the limiting groove.

[0011] Furthermore, the transmission mechanism is one of a belt transmission mechanism, a gear transmission mechanism and a chain transmission mechanism.

[0012] Furthermore, the high-pressure air source is a dual-channel air compressor, the power source is an electric motor, the electric motor is electrically connected to a power battery, and a controller is provided inside the control compartment, and the controller is electrically connected to the high-pressure air source and the power source, respectively.

[0013] Furthermore, an auxiliary block is fixedly connected to the top end of the adjusting rod, and the auxiliary block is used to rotate the adjusting rod.

[0014] Furthermore, the snow clearing mechanism includes a fixing plate and a snow pushing plate, one side of the fixing plate is fixedly connected to the ice breaking mechanism, and the other side of the fixing plate is fixedly connected to the snow pushing plate.

[0015] Furthermore, the snow pusher is a conical plate with two curved wings.

[0016] Compared with the prior art, the present invention provides an automatic track snow and ice removal vehicle, which has the following beneficial effects:

[0017] 1.

Combined with the ice-breaking function of the ice-breaking mechanism, it can quickly clear the snow and ice on the track at one time, improve the efficiency of rail snow removal, shorten the track construction time, and ensure the safety of rail vehicles.

[0018] 2. The automatic track snow and ice clearing vehicle can adjust the height of the ice crushing mechanism through the setting of the adjustment mechanism. The upper and lower baffles are used to allow the adjusting rod to rotate on the connecting frame without moving up and down. The limiting sleeve is fixed by the connecting plate. Therefore, when the adjusting rod rotates, the lifting column will move up and down. Due to the action of the limiting groove and the limiting block, the lifting column will only move vertically up and down without rotating. Since the lifting column is fixedly connected to the mounting frame, the up and down movement of the lifting column can adjust the distance between the main ice crushing wheel and the auxiliary ice crushing wheel and the track. The ice on the track is crushed by harmonic shock, rotary digging and extrusion crushing. The main ice crushing wheel and the auxiliary ice crushing wheel do not directly contact the track, thereby avoiding damage to the track.

[0019] 3. The automatic rail snow-clearing and ice-removing vehicle can simultaneously crush ice on the upper surface and both sides of the track through a vertically arranged main ice-crushing wheel and two inclined auxiliary ice-crushing wheels in the ice-crushing wheel assembly, thereby expanding the ice-crushing range and further ensuring the safety of rail transportation; through the setting of the universal coupling, the main ice-crushing wheel can drive the auxiliary ice-crushing wheels to crush ice at the same time.

[0020] The parts not involved in the device are the same as the existing technology or can be implemented by the existing technology. The present invention can quickly shovel the snow on the track and spread it to both sides of the track. At the same time, the floating ice on the track is squeezed and crushed by a non-contact gear machine, and the ice and snow powder is blown off by a high-pressure airflow. The snow and ice on the track can be quickly cleared at one time, the snow removal efficiency of the track is improved, the track construction time is shortened, and the safety of rail vehicle traffic is guaranteed.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] Reference Figure 1-5 An automatic track snow and ice removal vehicle comprises a vehicle body 1, an ice-breaking mechanism 2 and a snow-clearing mechanism 3. The ice-breaking mechanism 2 is installed at the front ends of both sides of the vehicle body 1, and the snow-clearing mechanism 3 is installed at the front end of the ice-breaking mechanism 2. A nozzle 18 is arranged on the side of the ice-breaking mechanism 2 close to the vehicle body 1. The nozzle 18 is connected to a high-pressure air source 17 through an air pipe. Here, the nozzle 18 is preferably arranged to be inclined toward the outside of the de-icing vehicle, so that the crushed ice generated by the ice-breaking mechanism 2 can be blown to the outside of the track.

[0029] The ice-breaking mechanism 2 includes a connecting frame 4, a power source 5 and an ice-crushing mechanism. One end of the connecting frame 4 is fixedly connected to the vehicle body mechanism 1, and the other end is fixedly connected to the snow-clearing mechanism 3. The bottom end of the connecting frame 4 is connected to the ice-crushing mechanism through an adjusting mechanism. The ice-crushing mechanism includes a mounting frame 6 and at least one group of ice-crushing wheel assemblies. Each group of ice-crushing wheel assemblies includes a vertically arranged main ice-crushing wheel 7 and two inclined auxiliary ice-crushing wheels 8. The bottom of the auxiliary ice-crushing wheel 8 is lower than the bottom of the main ice-crushing wheel 7, thereby realizing ice crushing operations on the upper surface of the track and on both sides of the track. The main ice-crushing wheel 7 and the auxiliary ice-crushing wheel 8 are both installed at the bottom of the mounting frame 6 through a mounting seat 9 with an opening on one side. The opening of the mounting seat 9 is set at the bottom, which is generally a U-shaped seat. Both ends of the wheel axle of the main ice-crushing wheel 7 The universal coupling 10 is respectively connected to the wheel axles of the two auxiliary ice-crushing wheels 8. The setting of the universal coupling 10 can realize the simultaneous rotation of the main ice-crushing wheel 7 and the auxiliary ice-crushing wheel 8. One side of the wheel axle of the main ice-crushing wheel 7 is connected to the output end of the power source 5 through a transmission mechanism. The transmission mechanism is one of a belt transmission mechanism, a gear transmission mechanism and a chain transmission mechanism. A protective plate 29 is also provided between the mounting frame 6 and the connecting frame 4 to protect the power source 5 and the adjustment mechanism. During operation, the main ice-crushing wheel 7 and the auxiliary ice-crushing wheel 8 use the teeth thereon to rotate and squeeze and crush the floating ice on the track, and the harmonic shock generated during operation will drive the track to vibrate, which is beneficial to the separation and crushing of the floating ice on the track.

[0030] The vehicle body structure 1 includes a frame 11, a driving wheel 12 and a control compartment 13. The control compartment 13 includes a storage box and a compartment cover. The compartment cover is covered on the storage box. A power battery 19 is arranged inside the control compartment 13. A high-pressure gas source 17 is fixedly installed inside the control compartment 13. The power battery 19 and the high-pressure gas source 17 are both arranged in the storage box. The driving wheel 12 is arranged at the bottom of the frame 11 through a wheel seat. The driving wheel 12 is an electric wheel, that is, a combination of a hub motor and a wheel. The motor wheel is already a prior art and will not be elaborated in this article. The driving wheel 12 is electrically connected to the power battery 19.

[0031] Adjacent mounting seats 9 are fixedly connected via reinforcing ribs 16 to enhance the structural strength of the ice-breaking mechanism 2 .

[0032] The adjusting mechanism includes an adjusting rod 21, a limiting sleeve 22 and a lifting column 23. The top of the adjusting rod 21 is rotatably connected to the connecting frame 4 and passes through the upper surface of the connecting frame 4. Two baffles 24 distributed up and down are fixedly connected to the outer wall of the top of the adjusting rod 21, and the two baffles 24 are respectively against the upper and lower surfaces of the connecting frame 4; the side wall of the limiting sleeve 22 is fixedly connected to a connecting plate 28, and the top of the connecting plate 28 is fixedly connected to the bottom of the connecting frame 4; the bottom end of the lifting column 23 is fixedly connected to the mounting frame 6, and the top is slidably connected to the inside of the limiting sleeve 22, the bottom of the adjusting rod 21 extends to the inside of the limiting sleeve 22, and is threadedly connected to the lifting column 23, a limiting groove 25 is provided on the outer wall of the limiting sleeve 22, and a limiting groove 25 is fixedly connected to the outer wall of the lifting column 23 The limit block 26 matches the positioning groove 25, and the limit block 26 is slidably connected in the limit groove 25. The adjusting rod 21 is provided with an external thread on the outer side wall inside the limiting sleeve 22. Due to the action of the upper and lower baffles 24, the adjusting rod 21 can rotate on the connecting frame 4 without moving up and down. Due to the action of the connecting plate 28, the limiting sleeve 22 is fixed. Therefore, when the adjusting rod 21 rotates, the lifting column 23 will move up and down. Due to the action of the limiting groove 25 and the limit block 26, the lifting column 23 will only move vertically up and down without rotating. Since the lifting column 23 is fixedly connected to the mounting frame 6, the up and down movement of the lifting column 23 can adjust the distance between the main ice crushing wheel 7 and the auxiliary ice crushing wheel 8 and the track, thereby achieving different deicing effects.

[0033] The high-pressure gas source 17 is a dual-channel air compressor, on which a solenoid valve is provided, which can supply air to the nozzles 18 on both sides at the same time. The power source 5 is an electric motor, on which a motor driver is provided. The motor is electrically connected to the power battery 19. A controller 20 is provided inside the control compartment 13, and the controller 20 is also provided in the storage box. The controller 20 is electrically connected to the solenoid valve in the high-pressure gas source 17 and the motor driver in the power source 5 through a 485 signal line, respectively, to realize the linkage start and stop of the motor and the air compressor to save unnecessary startup idling energy consumption. In this embodiment, the controller 20 adopts a 32-bit microcontroller with an ARM Cortex-M core, and the specific model is STM32F103VET6.

[0034] The top of the adjusting rod 21 is fixedly connected with an auxiliary block 27, which is used to rotate the adjusting rod 21, so that the adjusting rod 21 can be rotated by a tool. Figure 2 In the embodiment, the auxiliary block 27 is an outer hexagonal shape, which is convenient for operation with a common hexagonal wrench.

[0035] The snow clearing mechanism 3 includes a fixed plate 14 and a snow pushing plate 15. One side of the fixed plate 14 is fixedly connected to the ice breaking mechanism 2, and the other side is fixedly connected to the snow pushing plate 15 for pushing away the accumulated snow to facilitate the ice breaking mechanism 2 to perform ice crushing operations.

[0036] The snow pusher 15 is a cone plate with arc-shaped wings, which can effectively push and spread the accumulated snow to both sides of the track.

[0037] In the present invention, when in use, through the setting of the high-pressure air source and the nozzle, the crushed ice on the track can be swept after the ice-breaking mechanism breaks the ice, so as to avoid a large amount of crushed ice remaining on the track and improve the safety of rail transportation. The power battery in the control compartment provides electricity for the driving wheel and the power source, thereby realizing the walking drive of the vehicle body mechanism 1 and the ice-breaking drive of the ice-breaking mechanism. The ice-breaking wheel assembly on the ice-breaking mechanism utilizes the vertically arranged main ice-breaking wheel 7 and the inclined auxiliary ice-breaking wheel 8 thereon to perform harmonic shock, rotational excavation and extrusion crushing on the floating ice on the track surface and the ice on both sides, thereby ensuring the ice-breaking effect and further ensuring the safety of rail transportation. The controller is used to simultaneously control the power source 5 and the high-pressure air source 17 to realize the linkage start and stop of the motor and the air compressor, so as to save unnecessary startup idling energy consumption.
