Description

Technical Field

[0001] The present invention relates to a tread cleaning device, particularly a sandblasting cleaning device. Background Art

[0002] The common tread cleaning devices on the market currently mainly consist of a cylinder, a piston rod, and a cleaning head. The mainstream products still use a pneumatic device as the power source. Since the cylinder uses air compression to push the piston rod to work, it is impossible to control the feed amount of the cleaning head when cleaning the tread. And when the cleaning device contacts the tread, due to bogie problems, the cleaning shoe (brake shoe) rebounds when contacting the wheel set. Moreover, in some specific geographical areas of the high-speed rail system, rain and snow weather also pose challenges to the high-speed rail. In winter, snowfall may cause the track to be covered with snow or ice, which will directly affect the braking performance and driving stability of the train, thus affecting the train dispatching and operation. Since there is no better device to replace it, the current rail transit operation still uses a common tread cleaning device. This device not only cannot accurately guarantee the feed amount, but also after the cleaning head works, in the face of rain and snow weather, the wheel adhesion decreases, resulting in the problem of wheel slip still being unsolved. Furthermore, the existing technology has high space requirements in the direction of the wheel axis (for example, it is easily restricted by the clamping hanger seat, etc. in terms of space), and it is difficult to be applied to some rail vehicles with a small installation space in the direction of the wheel axis. Since the cleaning brake shoe needs to be replaced frequently, it increases the labor time cost and further exacerbates the wear of the wheel set.

[0003] In summary, how to increase wheel adhesion and avoid wheel slip has become an urgent problem for researchers in this field to solve. Summary of the Invention

[0013] The present invention will be further described below with reference to the drawings and embodiments.

[0014] Figure 1 is a schematic structural diagram of the present solution; Figure 2 is a cross-sectional view of the present solution. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] The present invention will now be described in further detail with reference to the drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, and therefore only showing the components related to the present invention.

[0016] As Figure 1-2As shown in the figure, this embodiment is a sandblasting cleaner, including: a power box 1; a linear actuator 2, whose fixed end is connected to the power box 1, and whose movable end is provided with a brake shoe 3; a mixing tower 4, which is arranged at the movable end of the linear module 2 and is arranged above the brake shoe 3; a whistle 5, which is arranged at the output end of the mixing tower 4; a water storage tank 5, which is arranged on one side outside the power box 1 and is connected to the mixing tower 4 through a connecting pipe 7; a sand storage tank 6, which is arranged on the other side outside the power box 1 and is connected to the mixing tower 4 through a connecting pipe 7; In this embodiment, the linear actuator 2 drives the brake shoe and the mixing tower 4 to move forward linearly. The brake shoe 3 contacts the wheel set to clean the wheel set. When the vehicle faces bad weather conditions, the sand in the sand storage tank 6 and the water in the water storage tank 5 enter the mixing tower 4 through the connecting pipe 7. After mixing, the sand mixed with water vapor is sprayed onto the wheel set by the whistle 5. In this way, the efficiency of sand spraying and adhesion to the wheel is increased, and thus the adhesion of the wheel set is increased, avoiding the occurrence of slipping problems.

[0017] As Figure 1-2 shown, in some possible embodiments, the linear actuator 2 includes: an electric push rod 21, which is arranged in the power box 1, and whose push rod 21 passes through the power box 1; a connecting piece 22, which is fixed at the end of the electric push rod 21; a sleeve 23, which is sleeved outside the electric push rod 21 and is fixedly connected to the electric push rod 21 through the connecting piece 22. In this embodiment, the linear actuator 2 adopts the form of an electric push rod 21, which can avoid the problem of the brake shoe rebounding when contacting the wheel set, achieving the effect of controllable brake shoe stroke. The power source of the electric push rod 21 is realized by driving the rotation of the turbine 25 and the worm 26 by a servo motor 24 to linearly expand and contract the push rod. The push rod is connected to the sleeve 23 through the connecting piece 22, and the end of the sleeve 23 is used to connect the mixing tower 4 and the brake shoe 3. When the linear actuator 2 is started, the mixing tower 4 and the brake shoe 3 are moved closer to the wheel set to clean or sandblast the wheel set. As Figure 1-2 shown, in some possible embodiments, since during the sandblasting process, sand may enter the power box 1 through the gap between the power box 1 and the push rod, or the push rod may be worn. To avoid the occurrence of the above situation, this embodiment further includes: a sealing bellows 27, which is sleeved outside the push rod, one end of which is connected to the connecting piece 22, and the other end of which is hermetically connected to the outer wall of the power box 1; In this solution, by setting the sealing bellows 27, the sealing performance between the push rod and the power box 1 is ensured, and sand will not enter the power box 1 or wear the push rod. The sealing bellows 27 changes axially as the push rod expands and contracts.

[0018] As Figure 1-2As shown, in some possible embodiments, the brake shoe 3 is detachably provided at the end face of the sleeve 23, and a mixing tower 4 is provided at the top of the sleeve 23 near the end face; In this embodiment, the brake shoe 3 is provided below the mixing tower 4.

[0019] As Figure 1-2 As shown, in some possible embodiments, in order to achieve the detachable connection between the brake shoe 3 and the sleeve 23, this solution adopts that an installation groove 231 is opened at the end face of the sleeve 23 along its axial direction, and first positioning protrusions 232 are oppositely arranged at the inner wall of the installation groove 231; a plurality of support legs 32 are extended from the mounting seat 31 of the brake shoe 3 towards the installation groove 231, an elastic member 8 is arranged between adjacent two support legs 32, and a second positioning protrusion 33 matching the positioning protrusion 232 is protrudingly arranged on the outermost support leg 32; When the brake shoe 3 and the sleeve 23 are in a connected state, a plurality of support legs 32 of the mounting seat 31 of the brake shoe 3 are located in the installation groove 231 of the sleeve 23, two second positioning protrusions 33 are located on the left side of the first positioning protrusion 232, and a spring 8 is arranged between the support legs 32. Under the action of the spring 8, the outermost support leg 32 can always be in contact with the inner wall of the installation groove 231, and the end spacing between the two second positioning protrusions 33 is greater than the end spacing between the two first positioning protrusions 232, so that the brake shoe 3 and the sleeve 23 cannot be separated; When the brake shoe 3 and the sleeve 23 need to be separated, press the two outermost support legs 32, the two support legs 32 move closer to the center, the spring 8 is in a compressed state, until the end spacing between the second positioning protrusions 33 is less than the end spacing between the two first positioning protrusions 232, and at this time, the separation of the brake shoe 3 and the sleeve 23 can be achieved.

[0020] Taking the above ideal embodiments according to the present invention as an inspiration, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this invention. The technical scope of this invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
