Abstract
Description
Technical Field
[0001] The present application relates to the field of track detection technology, and in particular to a switch device for track detection equipment. Background Art
[0002] Track inspection equipment is used for track inspection, such as flaw detection, profile detection, track inspection, etc. It usually includes two symmetrically arranged inspection units. Moreover, since the inspection environment has high requirements for stability, the running mechanism of the track inspection equipment is different from that of the train. Its running mechanism includes running wheels and supporting wheels. Specifically, running wheels are arranged below the inspection unit, and supporting wheels are arranged on the side. The running wheels are used to run on the top surface of the rails, and the supporting wheels are fitted with the inner side of the rails to achieve limit positioning, so as to provide a stable environment for inspection.
[0003] When the track inspection equipment detects the condition of the rails, it runs close to the railway track and sometimes needs to pass Figure 1 The railway turnout shown is a line connection device that allows locomotives and vehicles to transfer from one track to another. The line is complex and its main component is the switch core for achieving guidance.
[0004] In order to ensure that the track inspection equipment can pass through the turnout smoothly and turn to the rail to be inspected, turnout devices are usually installed at the front and rear ends of the track inspection equipment. Figure 2 As shown, the track inspection device A consists of a fixed bracket 3 and guide blocks 4, with the turnout device B symmetrically mounted on both sides of the track inspection device A. When the device passes through the turnout area, the guide blocks 4 of the turnout device first contact the tip of the turnout core. At the moment of contact, the guide blocks 4 move at a certain angle, following the contact surface. The track inspection device then moves to the rail to be inspected in accordance with the angle of the guide blocks 4.
[0005] However, the existing switch devices have large guiding resistance, resulting in a short lifespan. In addition, the guiding is unstable and the vibration is large, which makes the track detection equipment unstable and produces vibration / jumping, which in turn causes incomplete and deviation in the rail detection of the switch area. At the same time, it is also easy to cause damage to the internal electronic components of the detection equipment and loosen the cable joints, affecting the detection accuracy and the life of the detection equipment. Utility Model Content
[0006] The present application aims to address the problems of poor guiding stability and high maintenance costs associated with existing turnout devices. Therefore, the present application provides a turnout device for track inspection equipment. By utilizing the guide wheels of a first guide assembly and the rollers of a second guide assembly to improve contact with the side of the turnout core and synchronize rotation with travel, the device improves guiding stability, reduces wear, and reduces maintenance costs.
[0007] The embodiment of the present application provides a switch device for track detection equipment, comprising a mounting frame, and a first guide assembly and a second guide assembly sequentially arranged on the mounting frame along the length direction of the mounting frame;
[0008] The first guide assembly is disposed at an end of the mounting frame, and includes a first connecting shaft and a guide wheel rotatably sleeved on the first connecting shaft. The first connecting shaft is vertically disposed relative to a horizontal plane. The guide surface of the guide wheel is driven by the first connecting shaft to contact the side surface of the branch core and can rotate around the first connecting shaft.
[0009] The second guide assembly includes a second connecting shaft and a roller rotatably mounted on the second connecting shaft. The second connecting shaft is horizontally arranged and tilts to one side as it moves away from the first guide assembly. The tilt angle is ≤ 1 / 2 of the switch core angle. The roller has a first length and covers the second connecting shaft. The drum surface of the roller contacts the side surface of the switch core along with the second connecting shaft and rotates under the guidance of the slope of the side surface of the switch core.
[0010] By adopting the above technical solution, the rail to be inspected is fully guided by the two-step guiding deflection of the first guide assembly and the second guide assembly, which can reduce the impact force and thus improve the guiding stability; moreover, when passing through the turnout, the guide wheel of the first guide assembly of the device first passes through the harmful space to contact the tip of the turnout core and guides it to the rail to be inspected, and utilizes the guide surface and self-rotation of the guide wheel to achieve tangential contact with the turnout core, so that the guide wheel will rotate when subjected to friction to remove the friction force, thereby further improving the guiding stability; since the turnout core has a slope, that is, it is wide at the bottom and narrow at the top and forms an angle as a whole, after the guide wheel passes through the front end of the turnout core, the roller of the second guide assembly touches the slope of the turnout core to achieve rolling through, and achieves contact with the turnout core along a spiral line, further improving the guiding stability, and facilitating the track detection equipment to pass smoothly and stably through the harmful space and the front end of the turnout core in the turnout area under the traction of the device, thereby improving the detection reliability; at the same time, the guide wheel of the first guide assembly and the roller of the second guide assembly both rotate through the turnout, which can slow down the loss, thereby extending the service life of the device and reducing the maintenance cost.
[0011] In some embodiments, a plurality of bearings are sleeved on the second connecting shaft, and the roller is sleeved on the plurality of bearings.
[0012] The above technical solution improves the stability of the roller's rotation along the slope of the switch core, and improves the overall structural strength of the second guide assembly, thereby increasing the bearing capacity of the device, and further improving the stability of the track detection equipment towed by the device in the switch area.
[0013] In some embodiments, two of the first guide assembly and two of the second guide assembly are provided, and are symmetrically arranged at both ends of the mounting frame.
[0014] The adoption of the above technical solution facilitates the device to guide the crossing of the turnout in both the forward and backward directions, thereby improving the flexibility of the device.
[0015] In some embodiments, the first guide assembly and the end of the second guide assembly are separated by a first distance, and the first distance is proportional to the inclination angle of the second connecting shaft of the second guide assembly.
[0016] By adopting the above technical solution, the distance between the first guide assembly and the second guide assembly is proportional to the angle of the switch core. Therefore, the larger the angle of the switch core, the later the second guide assembly contacts the switch core, and the greater the guiding deflection of the first guide assembly on the device, thereby reducing the deviation angle between the second guide assembly and the switch core, thereby improving the guiding stability of the second guide assembly.
[0017] In some embodiments, the mounting bracket is connected to the first guide assembly via a mounting seat;
[0018] The mounting seat is L-shaped, and one end of the mounting seat is connected to the mounting frame, and the other end is located in front of the end of the mounting frame;
[0019] The first connecting shaft of the first guide assembly is vertically arranged at the end of the mounting seat located in front of the end of the mounting frame.
[0020] By adopting the above technical solution, the first guide assembly can be separated from the mounting frame by disassembling and separating the mounting seat and the mounting frame, thereby facilitating maintenance.
[0021] In some embodiments, both ends of the second connecting shaft are provided with shaft covers, the shaft covers have arc guide surfaces, and the edges of the arc guide surfaces are flush with the edges of the roller;
[0022] A connecting column is provided between the shaft cover and the mounting bracket, and the second connecting shaft is connected to the mounting bracket through the shaft cover and the connecting column.
[0023] By adopting the above technical solution, the arc guide surface of the shaft cover is connected with the roller, which improves the stability of the device when it switches from contacting the switch core through the first guide component to contacting the switch core through the second guide component, thereby further improving the guiding stability of the device.
[0024] In some embodiments, the second guide assembly has a proximal end and a distal end disposed opposite each other along the first length, and the proximal end is proximal to the first guide assembly;
[0025] The mounting frame is also provided with a supporting wheel for abutting against the side of the rail, the supporting wheel is arranged corresponding to the distal end of the second guide assembly, and the abutting surface of the supporting wheel protrudes from the distal edge of the second guide assembly in the direction toward the side of the rail.
[0026] By adopting the above technical solution, the supporting wheel of the device can replace the supporting wheel of the track detection equipment, and the supporting wheel protrudes relative to the first guide assembly and the second guide assembly, so that when the second guide assembly passes through the switch core and is located on the conventional straight section rail, the supporting wheel will replace the first guide assembly and the second guide assembly to contact the rail, so that the first guide assembly and the second guide assembly only work in the switch area, slowing down the loss, extending the service life, reducing the maintenance cost, and at the same time, avoiding affecting the track detection equipment from running on the conventional rail.
[0027] In some embodiments, the horizontal cross-section of the mounting frame is trapezoidal;
[0028] The first guide assembly, the second guide assembly and the supporting wheel are all arranged below the mounting frame, and the guide surface of the first guide assembly, the cylindrical surface of the second guide assembly and the abutment surface of the supporting wheel all protrude from the lateral edge of the mounting frame.
[0029] By adopting the above technical solution, the mounting frame can be placed as close as possible to the first guide assembly, the second guide assembly and the supporting wheel, thereby improving the overall compactness and structural strength of the device.
[0030] Other features and corresponding beneficial effects of the present application are described in the latter part of the specification, and it should be understood that at least some of the beneficial effects become obvious from the description in the specification of the present application.

[0049] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.
[0050] See Figure 1-2 , Figure 1 This is a structural diagram of the railway turnout area; Figure 2 This is a structural diagram of the existing track detection device and the existing switch device after assembly.
[0051] It should be noted that during the operation of the existing switch device B, the switch device B will first contact the tip of the switch core 1 in the switch area. Since the existing track detection equipment A is manually pushed or towed to a power trolley, when passing through the switch area, the switch device B will generate a large impact at the moment it contacts the tip of the switch core 1 to complete the guidance, which will cause vibration / jumping to the track detection equipment A, thereby causing incomplete and deviation detection of the rails in the switch area.
[0052] At the same time, the vibration / jumping of track detection equipment A may also damage the electronic components inside the equipment, and there is a high probability that the equipment will directly stop working; or it may cause the cable connectors to loosen, resulting in abnormal communication, increasing the maintenance time of on-site staff and greatly increasing the time cost.
[0053] Moreover, when the existing switch device B passes the tip of the switch core 1 during operation, the guide block 4 rubs hard against the slope of the switch core 1, which aggravates the wear of the guide surface of the guide block 4, shortening the after-sales maintenance cycle and increasing costs.
[0054] See Figure 3-4 , Figure 3 This is a schematic structural diagram of an embodiment of the present application; Figure 4 It is a schematic top perspective view of an embodiment of the present application.
[0055] In response to the above problems, an embodiment of the present application provides a switch device for track detection equipment, which has high guiding stability and low maintenance cost.
[0056] Specifically, the switch device includes a mounting frame 10, and a first guide assembly 20 and a second guide assembly 30 sequentially arranged on the mounting frame 10 along the length direction of the mounting frame 10, and the first guide assembly 20 is arranged at the end of the mounting frame 10. The first guide assembly 20 and the second guide assembly 30 are used for two-step guiding deflection to achieve complete guidance of the rail to be inspected, which can reduce impact force and thus improve guiding stability.
[0057] In one embodiment, two first guide assemblies 20 and two second guide assemblies 30 are provided and symmetrically arranged at both ends of the mounting frame 10, so that the device can guide the switch in both the forward and backward directions, thereby improving the flexibility of use of the device.
[0058] Please combine Figure 3-4 , and see Figure 5 , Figure 5 This is an exploded diagram of an embodiment of the present application.
[0059] In one embodiment, the first guide assembly 20 includes a first connecting shaft 21 and a guide wheel 22 rotatably mounted on the first connecting shaft 21. The first connecting shaft 21 is disposed vertically relative to a horizontal plane. Driven by the first connecting shaft 21, the guide surface of the guide wheel 22 contacts the side surface of the switch core 1 and can rotate about the first connecting shaft 21. Specifically, as the device moves, the guide wheel 22 rolls against the side surface of the switch core 1.
[0060] In this method, when passing through a turnout, the guide wheel 22 of the first guide assembly 20 of the device first passes through the hazardous space 2, contacts the tip of the turnout core 1, and guides it to the rail to be inspected. The guide surface and self-rotation of the guide wheel 22 achieve tangential contact with the turnout core 1, causing the guide wheel 22 to rotate when subjected to friction, relieving the frictional force and further improving guidance stability. Furthermore, the self-rotation of the guide wheel 22 through the turnout reduces wear on the guide wheel 22, thereby extending the service life of the device and reducing maintenance costs.
[0061] In one embodiment, the first guide assembly 20 further includes an end cap 23 connected to the end of the first connecting shaft 21 to prevent the guide wheel 22 from detaching from the first connecting shaft 21. The end cap 23 covers most of the bottom surface of the guide wheel 22, thereby protecting the guide wheel 22 and extending its service life. Preferably, both the guide wheel 22 and the end cap 23 are made of high-strength steel.
[0062] In one embodiment, the mounting frame 10 is connected to the first guide assembly 20 via the mounting seat 11 .
[0063] The mounting base 11 is L-shaped, with one end of the mounting base 11 connected to the mounting frame 10 and the other end located in front of the end of the mounting frame 10. The first connecting shaft 21 of the first guide assembly 20 is perpendicularly disposed at the end of the mounting base 11 located in front of the end of the mounting frame 10. This allows the mounting base 11 and the mounting frame 10 to be disassembled and separated, allowing the first guide assembly 20 to be separated from the mounting frame 10 for easy maintenance.
[0064] In one embodiment, the second guide assembly 30 includes a second connecting shaft 31 and a roller 32 rotatably mounted on the second connecting shaft 31. The second connecting shaft 31 is horizontally disposed and tilts toward the side as it moves away from the first guide assembly 20, with an inclination angle ≤ 1 / 2 of the angle a of the switch core 1. This ensures smooth passage of the second guide assembly 330 through the switch core 1. The roller 32 has a first length and covers the second connecting shaft 31. The roller surface of the roller 32 contacts the side of the switch core 1 along with the second connecting shaft 31, and the roller rotates guided by the slope of the side of the switch core 1. The roller 32 is preferably made of high-strength steel to extend its service life.
[0065] It should be noted that the switch core 1 not only has a side slope to guide the train to turn, but the side slope also has a slope, that is, the switch core 1 is wider at the bottom and narrower at the top, forming an overall angle.
[0066] Therefore, after the guide wheel 22 passes the front end of the switch core 1, the roller 32 of the second guide assembly 30 is in line contact with the switch core 1, which further improves the guiding stability and facilitates the track detection equipment to smoothly and stably pass through the harmful space 2 and the front end of the switch core 1 in the turnout area under the traction of this device, thereby improving the detection reliability.
[0067] Furthermore, since the inclined surface of the switch core 1 has a slope, the roller 32 passes through the switch core 1 while rotating, so that the contact line between the roller 32 and the switch core 1 is a spiral line around the surface of the roller 32. As a result, the roller 32 and the switch core 1 are not in the same position each time they make frictional contact, which greatly reduces the wear of the roller 32, thereby extending the service life of the device and reducing maintenance costs.
[0068] It can be understood that, in order to achieve the corresponding inclination of the roller 332 and the fork core 1, the inclination direction of the second connecting shaft 331 is toward the outside of its forward direction.
[0069] In one embodiment, shaft covers 35 are provided at both ends of the second connecting shaft 31. The shaft covers 35 have arc guide surfaces, and the edges of the arc guide surfaces are flush with the edges of the roller 32. The arc guide surfaces of the shaft covers 35 are connected with the roller 32, which improves the stability of the device when it switches from contact with the switch core 1 through the first guide assembly 20 to contact with the switch core 1 through the second guide assembly 30, thereby further improving the guiding stability of the device.
[0070] In one embodiment, a connecting column 12 is provided between the shaft cover 35 and the mounting frame 10, and the second connecting shaft 31 is connected to the mounting frame 10 through the shaft cover 35 and the connecting column 12, so that the second guide assembly 30 can be separated from the mounting frame 10 by disassembling and separating the connecting column 12 and the mounting frame 10, thereby facilitating maintenance.
[0071] Preferably, the connecting post 12 is threadedly connected to the mounting bracket 10 .
[0072] In one embodiment, the second guide assembly 30 has a proximal end and a distal end that are oppositely disposed along the first length, with the proximal end being proximal to the first guide assembly 20 .
[0073] The mounting frame 10 is also provided with a wheel 40 for abutting against the side of the rail. The wheel 40 corresponds to the distal end of the second guide assembly 30, and the abutting surface of the wheel 40 protrudes from the distal edge of the second guide assembly 30 in the direction toward the side of the rail, preferably by 2-5 mm.
[0074] In this manner, the supporting wheel 40 of the device can replace the supporting wheel 40 of the track detection equipment, and the supporting wheel 40 protrudes relative to the first guide assembly 20 and the second guide assembly 30, so that when the second guide assembly 30 passes through the switch core 1 and is located on the conventional straight section rail, the supporting wheel 40 will replace the first guide assembly 20 and the second guide assembly 30 to contact the rail, that is, the first guide assembly 20 and the second guide assembly 30 only work in the switch area, thereby reducing wear and tear, extending service life, and reducing maintenance costs, while avoiding affecting the track detection equipment from running on conventional rails.
[0075] It is understandable that when two first guide assemblies 20 and two second guide assemblies 30 are provided and symmetrically arranged at both ends of the mounting frame 10 , the supporting wheel 40 is arranged between the two groups of first guide assemblies 20 and second guide assemblies 30 .
[0076] In one embodiment, the supporting wheel 40 is centrally connected to the mounting frame 10 via a third connecting shaft 41. A supporting wheel bearing 42 is sleeved on the third connecting shaft 41, and the supporting wheel is connected to the supporting wheel bearing 42 to improve its rotational stability and reliability. Preferably, a supporting wheel end cap 43 is provided at the bottom of the supporting wheel 40 to prevent the supporting wheel 40 from disengaging from the supporting wheel bearing 42 and the third connecting shaft 41, and to provide protection for the bottom of the supporting wheel 40.
[0077] In one embodiment, the diameter of the guide wheel 322 is 18 mm, the diameter of the roller 332 is 21 mm, and the diameter of the supporting wheel 340 is 35 mm, so that the guide wheel 322, the roller 332 and the supporting wheel 340 can pass through the switch smoothly in sequence.
[0078] In one embodiment, the horizontal cross-section of the mounting bracket 10 is trapezoidal.
[0079] The first guide assembly 20, the second guide assembly 30 and the supporting wheel 40 are all arranged below the mounting frame 10, and the guide surface of the first guide assembly 20, the cylindrical surface of the second guide assembly 30 and the abutting surface of the supporting wheel 40 all protrude from the lateral edge of the mounting frame 10, so that the mounting frame 10 can be as close to the first guide assembly 20, the second guide assembly 30 and the supporting wheel 40 as possible, thereby improving the overall compactness of the device, so that the device as a whole can be closer to the side of the rail, and the structural strength of the device can also be improved, thereby improving the guiding stability.
[0080] In one embodiment, the ends of the first guide assembly 320 and the second guide assembly 330 are separated by a first distance L, where L is a buffer area for buffering the transition harmful space, and L≤the length of the harmful space. The overall length from the front end of the first guide assembly 320 to the end of the second guide assembly 330 is lengthened by the first distance L, so that the first guide assembly 320 and the second guide assembly 330 are smoothly connected, and the second guide assembly 330 cuts into the switch core 1 at a smaller angle, which facilitates the two to pass through the switch, and allows the wheel 340 to pass through the harmful space smoothly.
[0081] See Figure 6 , Figure 6 Schematic diagram of an explosion of the second guide assembly 30 in the embodiment of the present application, in which the connecting column 12 is omitted.
[0082] In one embodiment, a plurality of bearings 33 are sleeved on the second connecting shaft 31, and the roller 32 is sleeved on the plurality of bearings 33, which can improve the stability of the roller 32 rotating along the slope of the switch core 1, and improve the overall structural strength of the second guide assembly 30, thereby improving the bearing capacity of the device, and further improving the stability of the track detection equipment towed by the device in the switch area.
[0083] It should be noted that under normal conditions, the track detection equipment is supported on the rails by the running wheels below it, but when passing through the switch area, the running wheels will be skewed to a certain extent due to turning. At this time, the present application provides additional assistance through the second guide assembly 30 to achieve the support of the track detection equipment and improve its stability and safety when passing through the switch area.
[0084] In one embodiment, a spacer sleeve 34 is provided between two adjacent bearings 33 to ensure the stability of the position of each bearing 33 on the second connecting shaft 31 and effectively reduce the direct friction between the bearings 33, thereby extending the service life of the sleeve, reducing vibration, and improving rotation stability and reliability.
[0085] See Figure 7 , Figure 7 This is a schematic diagram of the usage status of an embodiment of the present application.
[0086] A single track detection device (detection unit) A1 is symmetrically installed with two switch devices B1 in this embodiment in the front and rear, thereby solving the instability caused by the impact generated when it contacts the switch core 1 when passing through the switch area, reducing the wear of components when passing through the switch area, improving the detection efficiency of the equipment and reducing labor costs and maintenance costs.
[0087] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
