Description

Technical Field

[0001] The invention relates to the technical field of components for rail transit basic braking systems, in particular to a tread cleaner. Background Art

[0002] The cleaning shoe of the tread brake acts directly on the wheelset tread of the wheel, which has a certain effect of improving wheel-rail adhesion and cleaning the wheel tread; the disc brake lacks cleaning of the wheel tread and there is a certain risk of low adhesion, so certain adhesion-increasing measures must be taken.

[0003] The existing tread sweeper has the following technical problems:

[0004] 1. The existing technology mainly uses a cylinder to push the cleaning shoe to clean the wheel pair tread. Since the cylinder compressed air has a time delay, the feeding amount of the cleaning head cannot be controlled;

[0005] 2. The existing technology cannot handle the large amount of sparks and metal dust generated when the cleaning shoe contacts the wheel set during cleaning. The metal dust affects the operation of circuit facilities and is prone to fire.

[0006] 3. There is no way to accurately guarantee and measure the temperature generated when the cleaning head contacts the wheelset tread in the prior art; this not only increases the frequency of cleaning shoe replacement, but also exacerbates the wear of the wheelset.

[0007] In summary, how to clean the wheelset tread has become an urgent problem that researchers in this field need to solve. Summary of the invention

[0008] The technical problem to be solved by the present invention is: how to clean the wheelset tread;

[0009] In order to solve the above technical problem 2, the technical solution adopted by the present invention is:

[0010] The present invention is a tread sweeper, comprising: a fixed box; a support plate, a linear telescopic module is arranged between the support plate and the fixed box; a cleaning shoe, which is arranged on the support plate and is suitable for cleaning the tread of a wheelset; two oppositely arranged dust caps, which are arranged on the support plate and located on both sides of the cleaning shoe, and suction holes are provided on the opposite surfaces of the two dust caps; a storage box, which is connected to the dust caps through a pipe; wherein the dust caps have a straight section and a convex section connected to the top of the straight section, and the spacing between the convex sections of the two dust caps is greater than the spacing between the straight sections.

[0011] Furthermore, the outer convex section is an arc-shaped structure.

[0012] In order to solve the above technical problem 3, further, a temperature sensor is provided at the support plate.

[0013] In order to solve the above-mentioned technical problem 1, further, the lifting module includes: a servo motor, which is arranged in the fixed box; two external threaded tubes, one end of which passes through the fixed box and is connected to the output shaft of the servo motor through a gear pair; two internal threaded tubes, which are connected to the corresponding external threaded tubes; and a lifting plate, the ends of the two internal threaded tubes are connected to the lifting plate.

[0014] Furthermore, a guide rod is arranged outside the fixed box; and a guide sleeve matching with the guide rod is arranged on the lifting plate.

[0015] Beneficial effects of the invention: The invention is a tread sweeper, and the scheme has the following advantages:

[0016] a) The present invention adopts a servo motor as the power source of the cleaning head. The servo motor drives the gear transmission to accurately control the feed amount, thereby reducing the loss of the cleaning head and reducing the railway operation cost;

[0017] b) The present invention adds a pair of special new structure dust suction caps at the terminal of the cleaning device, which can prolong the contact time with the metal dust and play a role in slowing down the flue gas flow. The central convex section provides a buffer space for the rising dust, effectively expanding the absorption area to better absorb the dust;

[0018] c) The present invention installs a pair of temperature sensors on the cleaning support to control the temperature generated when the cleaning head cleans the wheelset. When the temperature reaches the designed value, the cleaning head is separated from the wheelset to avoid damage to the cleaning head due to high temperature. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0020] Figure 1 It is a schematic diagram of the structure of the present invention;

[0021] Figure 2 It is a schematic diagram of the structure of the dust suction cap;

[0022] Figure 3 It is a cross-sectional view of the present invention. DETAILED DESCRIPTION

[0023] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0024] In order to solve the technical problem in the background technology that a large amount of sparks and metal dust will be generated when the cleaning shoe contacts the wheel pair during cleaning, which cannot be handled, and the metal dust will affect the operation of circuit facilities and easily cause fire.

[0025] Figure 1 Dust suction caps 2 are respectively arranged on the left and right sides of the middle support plate 1, and a cleaning shoe 3 is arranged between the two dust suction caps 2. The fixing box 4 is fixed on the vehicle. The support plate 1 performs a linear telescopic motion driven by the telescopic module to bring the cleaning shoe 3 into contact with and clean the wheelset tread. The dust and sparks generated between the two will be sucked into the dust suction cap 2 from the suction hole 23, and then sucked into the storage box 6 through the hose 5, so as to realize the treatment of sparks and metal dust and avoid the occurrence of fire.

[0026] As for the shape of the dust suction cap 2, the dust suction cap 2 is a hollow arc structure, such as Figure 3 As shown, the inner wall of the dust cap 2 is provided with a suction hole 23, the bottom of the dust cap 2 is a vertical section 21, and the top is a convex section 22, and the convex section 22 is an arc-shaped structure. The dust cap 2 on the left side of the figure has a middle part of the convex section 22 recessed to the left; the dust cap 2 on the right side has a middle part of the convex section 22 recessed to the right. Such a setting can generate drainage when the airflow passes through. The provision of the convex section 22 can prolong the contact time between the smoke and the inner wall of the dust cap 2, thereby slowing down the smoke airflow. The two central convex sections 22 provide a buffer space for the rising smoke, and the continuously rising dust provides a continuous thrust or expansion pressure to the dust that has reached the convex section 22, thereby guiding the dust to flow to both sides of the dust cap 2 and enter the suction hole 23.

[0027] In order to solve the technical problem that there is no way to obtain accurate guarantee in the background technology and the temperature generated when the cleaning head contacts the wheelset tread cannot be measured; not only the frequency of cleaning shoe replacement increases, but also the wear of the wheelset is aggravated.

[0028] Figure 1 Temperature sensors 7 are provided on both sides of the bottom of the middle support plate 1. When the temperature reaches the design value, the cleaning head 3 is separated from the wheelset to prevent the cleaning head 3 from being damaged due to high temperature.

[0029] In order to solve the technical problem that the existing technology in the background technology mainly uses a cylinder to push the cleaning shoe to clean the wheel pair tread, and the feeding amount of the cleaning head cannot be controlled due to the time delay of the cylinder compressed air.

[0030] Figure 2 A servo motor 8 is arranged in the fixed box 4, and external threaded tubes 9 are arranged on both sides of the fixed box 8. The external threaded tubes 9 are connected to the output ends of the servo motor 8 through gear transmission, so that the self-rotation of the two external threaded tubes 9 is realized. Two internal threaded tubes 10 are sleeved on the top of the two external threaded tubes 9, and a lifting plate 11 is arranged on the top of the two internal threaded tubes 10, and the lifting plate 11 is connected to the support plate 1.

[0031] When the servo motor 8 is started, it drives the external threaded tube 9 to rotate and drives the internal threaded tube 10 to move axially, thereby realizing the lifting and lowering movement of the lifting plate 11 and the linear movement of the cleaning head 3. The cleaning head 3 can be accurately fed to contact the wheelset tread, avoiding aggravated wear of the cleaning head 3.

[0032] In order to further ensure the accuracy of the travel of the lifting plate, in this solution, the lifting plate 11 and the fixed box 4 are connected by a guide sleeve 12 and a guide rod 13. One end of the guide sleeve 12 is connected to the lifting plate 11, and one end of the guide rod 13 is connected to the top outer wall of the fixed box 4. A guide connection is inserted between the guide sleeve 12 and the guide rod 13.

[0033] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
