Description

Technical Field

[0001] The invention relates to the technical field of EMU track equipment tooling, in particular to an EMU sand spreading, recovery and measurement tooling. Background Art

[0002] During the operation of the EMU, sand needs to be sprinkled on the rails and around the wheels to deal with the problem of slipping due to insufficient friction of the rails. When slipping occurs, the deceleration effect of the wheels will be seriously affected, resulting in the inability to brake normally and estimate the braking distance. Quartz sand will be sprayed in front of the wheels in advance through the sand-spreading device to increase the friction between the wheels and the rails. Different sand-spreading amounts and the adhesion area and adhesion viscosity of the rails jointly affect the braking distance of the EMU. Therefore, when abnormal friction occurs, the train needs to be self-checked quickly. Since the train scheduling adopts a unified time management method, there is no time to stop and get off the train for self-checking. The train self-checking can only install a large number of sensor equipment for sand quantity inspection due to the front and rear obstructions of the wheels. The simulation effect is poor and the reference effect is poor. It is costly and has poor applicability. When used for individual test simulations, the quartz sand cannot be recycled, which again leads to cost losses.

[0003] To achieve the above objectives, the present invention provides a sand spreading and recovery measurement tool for EMUs, which can solve the problems raised in the above background technology. Summary of the Invention

[0021] The present invention enables the collection component to be simultaneously applied to both ends of the wheel sets of the EMU by using the adjustment component and the pump box component, thereby forming two working states for the collection component. First, when the collection component is in front of the wheelset, the guide nozzle of the collection component can be used to collect the amount of sand sprayed by the sandblasting nozzle of the EMU for simulation. The guide nozzle can be adjusted to cover the area of ​​the original guide rail, thereby obtaining the amount of sand sprayed by the sandblasting nozzle and attached to the rail.

Second, when the collection component is located behind the wheelset, the bent guide tube is adjusted again so that the guide nozzle can be close to the guide rail to collect the sprayed sand and the attached sand in a concentrated manner, which can save the use of the sprayed quartz sand and reduce the amount of sand and gravel cleaning on the rail by railway personnel, which is of great significance.

[0022] In addition, the present invention uses an outward-turned pump box assembly and various flexibly adjustable components to achieve a detour of the collection assembly relative to the wheelset when the working mode is changed in the conventional equipment state, so that the sandblasting amount can still be self-checked and the sandblasted sand can be collected normally while driving, overcoming the difficulty of being unable to accurately control the sandblasting brake while driving;

[0023] The collection components in this tooling can be disassembled and used separately. The rails can be adsorbed and fixed using manually adjustable electromagnetic components. The blasted sand can also be directly collected. The simulated sand volume self-inspection can be performed on the individual blasting positions when the train is parked, thereby improving the portability of the simple tooling, facilitating safety inspections by train crews, and ensuring driving safety.

[0034] To facilitate understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the content disclosed in the present invention more thorough and comprehensive.

[0035] It should be noted that when an element is referred to as being "fixed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly used by those skilled in the art to which the present invention pertains. The terms used in the specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0037] The present invention will be further described in detail below with reference to the accompanying drawings.

[0038] In one embodiment of the present invention: Please refer to the attached Figure 1-3 , comprising a collecting assembly 1, an adjusting assembly 2 and a pump box assembly 6, wherein the pump box assembly 6 is fixed to the outer side of the wheelset of the EMU, and a helical gear groove 605 is provided on the side wall of the pump box assembly 6, wherein the helical gear groove 605 is used to guide the adjusting assembly 2 to reciprocate toward the driving direction;

[0039] The collecting component 1 is fixed on the adjusting component 2, and the upper part of the adjusting component 2 and the pump box component 6 are mutually limited and sleeved. A transverse driving gear 207 is also provided on the upper part of the adjusting component 2 to cooperate with the oblique gear groove 605 for driving; the inclination direction of the oblique gear groove 605 is toward the side of the vehicle; the collecting end of the collecting component 1 is connected with a measuring cylinder 3; the collecting component 1 includes a bent conduit 102, the outer wall of the bent conduit 102 is rotatably connected to the adjusting component 2, the inlet end of the bent conduit 102 is provided with a guide nozzle 101, and the measuring cylinder 3 is connected to the other end of the bent conduit 102; an air pump is provided on the EMU, and a recovery air nozzle 103 is connected upward to the side wall of the bent conduit 102, and the other end of the recovery air nozzle 103 is communicated with the air pump, and a filled-in filter cotton is provided at the interface between the bent conduit 102 and the measuring cylinder 3.

[0040] The working mode of this tool is as follows, which is divided into two working modes. First, the collecting component 1 is in front of the wheelset, and the guide nozzle 101 of the collecting component 1 can be used to collect the amount of sand sprayed from the sandblasting nozzle of the EMU for simulation. The guide nozzle 101 can be adjusted to cover the area of ​​the original guide rail, thereby obtaining the amount of sand blasted by the sandblasting nozzle and adhering to the rail. The amount can be visually observed through a measuring cup to improve the sandblasting effect. The action is to directly remove the connecting plate 201 on the top of the adjustment frame 104, release the fixed relationship between the adjustment component 2 and the collecting component 1, and in the parked state, start the electromagnetic component 107 to fix it on the rail. At this time, the electronic locking knob 105 is used to adjust the flip angle of the bending guide tube 102 so that the bending guide tube As shown in the figure, the tube 102 is attached to the upper part of the rail on the left side of the collecting component 1, and the guide nozzle 101 can contact the rail. At this time, the sandblasting nozzle is turned on to collect the sand, and the sandblasting is quantitatively performed multiple times. The quartz sand falls into the inside of the measuring cylinder 3 through the bent tube 102, so that the average amount of adhesion on the rail in a single sandblasting is measured according to the scale; in addition, when the train is running, the guide nozzle 101 cannot contact the rail, and there is no need to start the electromagnetic component 107. The adjustment component 2 is used to position it so that the guide nozzle 101 is above the rail. At this time, the sandblasting test is not performed through the measuring cup. In the running state, the recovery air nozzle 103 is connected to the air pump on the train, and the originally connected measuring cylinder 3 can be filtered and filled, so that the introduced quartz sand is recovered to the sand storage box through the recovery air nozzle 103;

[0041] Secondly, when the collecting component 1 is located behind the wheelset, the bent duct 102 is adjusted again so that the guide nozzle 101 can be close to the guide rail to collect the sprayed sand and attached sand, which can save the use of sprayed quartz sand and reduce the amount of sand and gravel cleaning on the rails by railway personnel, which is of great significance; the same as the above-mentioned method of connecting the air pump, increasing the air volume of the air pump, so that the bent duct 102 produces a small-range precise suction on the upper surface of the rail, sucking the quartz sand into the air duct, and also filling it at the falling position, and recovering the quartz sand into the sand storage box through the recovery air nozzle 103. Its movement method is that the adjustment component 2 rotates under the drive of the pump box component 6, and uses the gear part on the upper part of the adjustment component 2 to cooperate with the gear track to move the collecting component 1 to the reverse running side of the wheelset, and rotates and falls to the reference position after passing through the return groove 604. The adjustment component changes the adaptive position of the guide nozzle 101 to complete the functional transformation of the overall tooling.

[0042] In another embodiment of the present invention: Please refer to Figure 3-5 , the adjustment component 2 includes an adjustment frame 104, an electronic locking knob 105 is provided on the adjustment frame 104, and the driving end of the electronic locking knob 105 is connected to the outer wall of the bending guide tube 102; a limit knob 106 is provided at the bottom of the adjustment frame 104, and a connecting plate 108 is rotatably connected to the limit knob 106, and an electromagnetic component 107 is provided on one side of the connecting plate 108; the purpose of using the electromagnetic component 107 is to improve the portability of the device and to adapt to new working methods. When the parking self-inspection is applied to old-style transport trains, the parking self-inspection sandblasting system is a conventional maintenance method, and its improvement has great practical significance. The separate collection component 1 is separated from the car body for use, which is convenient for cleaning the car body. The sandblasting position of each position is detected and recorded to maintain better convenience. At the same time, it is also of great significance for the timely elimination of its tooling. The obsolete tooling parts on the EMU can be disassembled and assembled to carry out sandblasting experiments on old-style transport trains. During the movement of the EMU, the complete tooling is blocked by protruding stones, resulting in damage to the lower end collection component 1. The collection component 1 can be simply replaced to save costs; among them, the electronic locking knob 105 can conveniently adjust the relative relationship and covering relationship between the guide nozzle 101 and the rail position, and can be driven in a variety of ways, such as manual or electric. The position of the limit knob 106 is to limit the angle flip. After flipping, it can reduce the actual movement travel space for the movement of the entire complete workpiece, providing certain convenience.

[0043] In one embodiment of the present invention: Please refer to the attached Figure 3-5 , the adjustment component 2 further includes a connecting plate 201, and the collecting component 1 is fixedly connected to the connecting plate 201;

[0044] A vertical interface 202 is provided on the connecting plate 201, and a rotating column 203 is provided on the vertical interface 202. The upper end of the rotating column 203 is drivingly connected to the horizontal driving gear 207.

[0045] A rotation adjustment seat 204 is also fixed on the connecting plate 201, and one end of the rotation center of the horizontal drive gear 207 is connected to the rotation adjustment seat 204. The pump box assembly 6 includes an end side plate 601, and a return groove 604 is provided between the end side plate 601 and the oblique gear groove 605. The horizontal drive gear 207 extends upward into the return groove 604 and engages with the oblique gear groove 605 for driving; the two end side plates 601 are provided with a lateral rotation motor 602 on the side facing the outside, and a gear block drive pile 603 is connected between the driving ends of the two lateral rotation motors 602. One end of the rotating column 203 is provided with a gear block sleeve 206, which is sleeved on the outside of the gear block drive pile 603, and the gear block sleeve 206 is located on the gear block drive pile 603 for sliding connection; the lateral rotation stroke area of ​​the connecting plate 201 is included in the supplementary stroke of the return groove 604;

[0046] The rotation adjustment seat 204 is rotatably connected to a rotation block 209, and a drive motor 205 is provided inside the rotation block 209. The drive end of the drive motor 205 is connected to the transverse drive gear 207; the rotation block 209 has an external height adjustment slot 208, and the height adjustment slot 208 is used to adjust the installation height of the drive motor 205;

[0047] The overall adjustment method of the pump box assembly 6 and the adjustment assembly 2 to the collection assembly 1 is explained above. The following is an explanation of a detailed structural connection and operation method: the oblique gear groove 605 can be a wire groove fixed on the outer oblique side surface of the two end side plates 601, and the two side lateral rotation motors 602 are respectively fixed to the outward side of the two end side plates 601. The spacing between the end side plates 601 is preferably greater than the wheel pair diameter. The tooth block drive pile 603 and the tooth block sleeve 206 are spline-like connections. The relationship between the two is that the tooth block sleeve 206 can slide on the tooth block drive pile 603. When the lateral rotation motor 602 drives, the tooth block drive pile 603 rotates, driving the tooth block drive pile 603 to rotate. At this time, there is a rotation point facing upwards against the inner wall of the pump box assembly 6. The appropriate electric adjustment of the extension position of the drive motor 205 and the rotation position of the rotation adjustment seat 204 make the transverse drive gear 207 rotate in the return groove 604 to make its final position as shown in FIG. Figure 3It is shown that the lateral drive gear 207 is engaged with the oblique gear groove 605, and then the rotation adjustment seat 204 or the unidirectional rotation adjustment seat 204 is locked, and the installation height of the drive motor 205 of the lateral drive gear 207 or the fixed height adjustment slot 208 position is locked (electric or manual, adaptable to two methods). At this time, when the lateral drive gear 207 rotates, the upper tooth block sleeve 206 of the rotating column 203 follows the tooth block drive pile 603 and slides. When it slides to the return slot 604 position at the other end, the drive motor 205 is stopped to adjust the rotation adjustment seat 204 to rotate in the opposite direction, or the height adjustment slot 208 position is lowered so that the upper engagement position is disengaged, and then the lateral rotation motor 602 is rotated to make the collecting component 1 and the adjustment component 2 rotate and fall inside the return slot 604. After that, the adjustment component 2 is adjusted to the fixed state of the collecting component 1, and then measurement or sand and gravel recovery operations can be performed.
