[0040] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0041] Embodiment: Reference Figure 1 The multifunctional inspection vehicle for rail transit shown in the figure comprises a power inspection vehicle 1 running on a track 7, and further comprises a snow removing mechanism 2: when the power inspection vehicle 1 moves on the track 7, the snow layer 9 on the track 7 is removed;

[0042] An ice breaking mechanism 3 is used to break the ice layer 8 on the track 7 and form smaller ice blocks for subsequent cleaning;

[0043] A cleaning mechanism 4 is used to clean the ice blocks on the upper surface of the track 7;

[0044] The snow removing mechanism 2, the ice breaking mechanism 3 and the cleaning mechanism 4 are sequentially arranged and installed on the track vehicle 7 from left to right.

[0045] When the power inspection vehicle 1 walks on the track 7, the snow layer 9 on the upper end of the track 7 is removed by the snow removing mechanism 2 arranged thereon, so that the ice layer 9 is exposed, the ice layer 8 is broken by the ice breaking mechanism 3, smaller ice blocks are formed, and the smaller ice blocks or part of the powdery ice residues are cleaned away from the upper surface of the track 7 by the cleaning mechanism 4.

[0046] As a preferred embodiment in the present embodiment, as shown in Figures 1-4 The snow removing mechanism 2 comprises a mounting plate 201 fixedly arranged at the bottom of the front end of the power inspection vehicle 1, a push plate 202 is mounted at the front end of the mounting plate 201, and a hollow guide plate 203 in isosceles triangle structure is mounted at the front end of the push plate 202;

[0047] The ice breaking mechanism 3 comprises a U-shaped plate 301 rotatably arranged with a rotating cylinder 302, the rotating cylinder 302 is driven by a driving motor 303 mounted on the U-shaped plate 301, a plurality of pull ropes 304 are densely arranged on the rotating cylinder 302, and a breaking ball 305 is fixedly arranged at the end of each pull rope 304, and the U-shaped plate 301 is mounted on the mounting plate 201;

[0048] The cleaning mechanism 4 comprises a pipeline mounted on the power inspection vehicle 1, the upper end of the pipeline is connected with the air outlet end of an air compressor mounted on the power inspection vehicle 1, and a plurality of groups of air injection pipes 403 are outwardly and obliquely arranged at the lower end of the pipeline;

[0049] A baffle 205 is mounted on the mounting plate 201 and located at the right side of the rotating cylinder 302.

[0050] Before use, as shown in Figure 6 The artificial removes the snow layer 9 and the ice layer 8 on the part of the track 7 where the power maintenance vehicle 1 is placed, so that the lower end of the push plate 202 contacts the upper end of the ice layer 8, the front end of the push plate 202 contacts the snow layer 9, and the wheel set of the power maintenance vehicle 1 contacts the upper end of the track 7 from which the snow layer 9 and the ice layer 8 are removed.

[0051] In use, the power maintenance vehicle 1 is controlled to move on the track 7, and when moving, the isosceles triangle-shaped hollow guide plate 203 at the front end of the push plate 202 is inserted into the snow layer 9 and moves with the push plate 202, and the snow layer 9 is separated and moved to both sides under the guide of the inclined surface on the hollow guide plate 203, and finally separated from the track 7.

[0052] After the ice layer 8 is exposed, the rotating drum 302 collides with the ice layer 8 on the track 7 by using the breaking balls 305 thereon, so that the ice layer 9 is broken, and the small ice blocks or ice residues formed are blown to one side of the track 7 by the high-pressure gas sprayed from the inclined jet pipe 403 and finally separated from the track 7.

[0053] In the design, the snow layer 9 at the upper end of the track 7 is removed by the snow removing mechanism 2, so that the ice layer 9 is exposed (to avoid that the ice layer 9 cannot be completely broken by directly using the ice breaking mechanism 3, so the snow layer 9 is removed first), the ice layer 8 is broken by the ice breaking mechanism 3 to form small ice blocks, and the small ice blocks or part of the powder ice residues are cleaned from the upper surface of the track 7 by the cleaning mechanism 4, which can effectively remove the coverings on the track 7 and provide convenience for subsequent flaw detection.

[0054] It should be noted that: first, the baffle 205 can prevent ice or ice block from splashing to the rear of the track 7 that has been passed, which affects the subsequent flaw detection; second, to reduce the friction between the lower end of the push plate 202 and the upper end of the ice layer 8, a ball can be arranged at the lower end of the push plate 202, and the arrangement of the ball can enhance the extrusion of the ice layer 8, which is beneficial to crushing or cracking the ice layer 8 (only for the thinner ice layer 8), assisting in breaking the ice layer 8, and being beneficial to the complete removal of the ice layer 8 on the upper end of the track 7; third, the lower end of the baffle 205 and the upper end of the track 7 have a certain height, allowing the ice or ice block generated to pass from below the baffle 205; fourth, the above-mentioned electrical equipment is electrically connected with the PLC controller on the power maintenance vehicle 1, and the power maintenance vehicle 1 is provided with a power supply for providing electric energy for each electrical equipment; fifth, the push plate 202 can be arranged at a certain inclination angle with the track 7, so that the push plate 202 has a guiding effect on the snow when moving, and then the snow is guided to one side of the track 7; sixth, when the breaking ball 305 strikes the track 7, the track will vibrate, which helps to expose or expand the small cracks on the track. These cracks that are originally difficult to detect may become more obvious under the action of vibration, so that they are more easily detected during flaw detection, improving the flaw detection accuracy.

[0055] As a preferred embodiment in the present embodiment, as shown in Figure 2 The bottom of the power maintenance vehicle 1 is provided with two groups of square rods 6, and the mounting plate 201 is slidably penetrated by the square rods 6;

[0056] The pipeline includes a fixed pipeline 401 fixedly installed on the power maintenance vehicle 1, and a movable pipeline 402 slidably arranged in the inner cavity of the fixed pipeline 401. A plurality of air jets 403 are arranged at the lower end of the movable pipeline 402. An elastic sleeve is fixedly arranged on the outer wall of the movable pipeline 402, and the outer wall of the elastic sleeve slidably abuts against the inner wall of the fixed pipeline 401.

[0057] Since the mounting plate 201 can slide on the square rod 6, the push plate 202 can move up and down. When the lower end of the push plate 202 moves from the thinner ice layer 8 to the thicker ice layer 8, the mounting plate 201 will slowly move upwards, thereby adaptively driving the rotating drum 302 (maintaining a certain height space between the rotating drum 302 and the upper end of the ice layer 8, which is beneficial to the relatively intense impact between the breaking ball 305 driven by the rotating rope 304 and the ice layer 8. If the rotating drum 302 is too close to the ice layer 8, the rotation of the rotating rope 304 will be hindered, and the breaking ball 305 cannot form a relatively intense impact with the ice layer 8) and the air jet 403 to move upwards (maintaining a certain distance from the ice layer 8, which is beneficial to the comprehensive coverage of the strong air flow on the upper end of the track 7).

[0058] It should be noted that positioning through holes can be arranged on the square rod 6 and the mounting plate 201, when not in use, the mounting plate 201 can be moved upwards and inserted into the two positioning through holes through the positioning pin, so as to limit the position of the mounting plate 201, and avoid the contact and friction between the push plate 202 and the lower end of the broken ball 305 and the ground when the wheel set of the power maintenance trolley 1 rolls on the ground.

[0059] As a preferred embodiment in the present embodiment, a swing mechanism is further arranged to drive the rotating rotating drum 302 to swing back and forth along the horizontal direction with a small amplitude.

[0060] The original rotating drum 302 only drives the broken ball 305 to move in a circular motion through rotation, and the knocking point is concentrated on a fixed track. By arranging the swing structure, the horizontal swing of the two ends of the rotating drum 302 makes the track movement of the broken ball 305 more diversified, and the frozen layer 8 can be knocked more comprehensively.

[0061] As a preferred embodiment in the present embodiment, as shown in Figure 3 and Figure 4 , the swing mechanism includes a mounting frame 308 mounted on the mounting plate 201, a reciprocating screw rod 312 rotatably arranged on the mounting frame 308, the reciprocating screw rod 312 being driven by a swing motor 309 mounted on the mounting frame 308, a reciprocating nut 310 being sleeved on the reciprocating screw rod 312, and a toothed plate 311 being mounted on the side end of the reciprocating nut 310.

[0062] A rotating shaft 306 is fixed at the upper end shaft center of the U-shaped plate 301, and the lower end of the rotating shaft 306 is rotatably arranged on the mounting plate 201. A gear 307 meshingly connected with the toothed plate 311 is fixed to the upper end of the rotating shaft 306.

[0063] During operation, the swing motor 309 is controlled to control the reciprocating screw rod 312 to rotate, so that the reciprocating nut 310 drives the toothed plate 311 to move back and forth, and finally the rotating drum 302 swings back and forth along the horizontal direction with a small amplitude through the cooperation of the gear 307 and the rotating shaft 306. This can increase the diversified track movement of the broken ball 305, and the frozen layer 8 can be knocked more comprehensively, which is conducive to the complete removal of the subsequent frozen layer 8.

[0064] It should be noted that the overhead swing trajectory of the rotating drum 302 is as shown in Figure 7 , wherein the swing angle θ of the rotating drum 302 to both sides along the central axis is controlled to be between 5° and 9°. If the angle is too small, it is still close to the original designed fixed track knocking, and cannot fully utilize the angle diversity brought by the swing. If the angle is too large, the broken ball 305 may move out of control, and the coupling of the centrifugal movement of the broken ball 305 and the swing may cause the broken ball 305 to be wound by the pull rope 304, resulting in a decrease in the ice breaking effect.

[0065] As a preferred embodiment in the present embodiment, an automatic adjusting unit 5 is further arranged to automatically adjust the rotating speed of the rotating drum 302 and the air flow intensity of the air jet pipe 403 according to the thickness of the ice layer 8 on the track 7.

[0066] With the increase of the thickness of the ice layer 8, the rotating speed of the rotating drum 302 needs to be increased correspondingly to increase the impact intensity between the broken balls 305 and the ice layer 8; when the thickness of the ice layer 8 decreases, the rotating speed of the rotating drum 302 needs to be decreased correspondingly to reduce the power consumption;

[0067] With the increase of the thickness of the ice layer 8, more ice blocks or ice residues will be produced after being broken, and the air flow intensity of the air jet pipe 403 is increased to quickly remove the ice blocks or ice residues thereon; when the thickness of the ice layer 8 decreases, less ice blocks or ice residues will be produced after being broken, and the air flow intensity of the air jet pipe 403 is decreased to reduce the power consumption.

[0068] As a preferred embodiment in the present embodiment, as shown in Figure 2 and Figure 5 the automatic adjusting unit 5 includes two groups of current regulators 501 and a stand 505 fixedly arranged at the upper end of the mounting plate 201, the two groups of current regulators 501 are fixedly arranged at the bottom of the power maintenance vehicle 1, and the two groups of current regulators 501 are electrically connected with the air compressor and the driving motor 303 respectively;

[0069] The adjusting knobs 502 of the two groups of current regulators 501 are each provided with a groove, and the groove includes a vertical groove 503 and an arc-shaped groove 504 which are connected together from top to bottom;

[0070] The two groups of stands 505 are each provided with a slide rod 506, and the outer ends of the two groups of slide rods 506 are located in the groove.

[0071] When the thickness of the ice layer 8 increases, the mounting plate 201 will drive the stand 505 to move upward, the adjusting knob 502 is rotated through the slide rod 506, the current flowing into the air compressor and the driving motor 303 is increased, the power of the air compressor and the driving motor 303 when working is increased, and finally the rotating speed of the rotating drum 305 and the air flow intensity of the air jet pipe 403 are increased;

[0072] Correspondingly, when the thickness of the ice layer 8 decreases, the current flowing into the air compressor and the driving motor 303 is increased, and finally the rotating speed of the rotating drum 305 and the air flow intensity of the air jet pipe 403 are decreased;

[0073] The automatic adjusting unit 5 can automatically adaptively adjust.

[0074] As a preferred embodiment in the present embodiment, as shown in Figure 2As shown, the two groups of push plates 202 are arranged at intervals, and the gap between the two groups of push plates 202 is greater than the gap between the adjacent two tracks 7.

[0075] The lower ends of the two groups of push plates 202 are fixed with contact heads, and the two side ends of the contact heads are provided with guide inclined surfaces 204.

[0076] The existing tracks 7 have gaps between the end portions of adjacent tracks 7 when installed to avoid the influence of thermal expansion and contraction. In addition, the upper end surfaces of the adjacent two end tracks 7 have a certain height difference due to the soil environment factors. Therefore, two groups of push plates 202 are arranged, and the gap between the two groups of push plates 202 is greater than the gap between the adjacent two tracks 7, so as to avoid the lower end of the push plate 202 inserted into the gap to hinder the movement of the push plate 202. In addition, the two side ends of the contact head are provided with guide inclined surfaces 204, which can contact the guide inclined surface 204 of the push plate 202 and lift the mounting plate 201, so that the push plate 202 can smoothly pass through the gap.

[0077] It should be noted that the lower end of the hollow guide plate 203 is located above the contact head.

[0078] As a preferred embodiment in this embodiment, as shown in Figure 8 A heat spray pipe 11 and a heat preservation pipe 10 with a long spiral electric heating pipe inside are further arranged, the left end of the heat preservation pipe 10 is connected with the air inlet end of the heat spray pipe 11 through a heat preservation hose, the heat spray pipe 11 is installed on the push plate 202, and the right end of the heat preservation pipe 10 is connected with the air outlet end of the air compressor.

[0079] The long spiral electric heating pipe is used to heat the gas, and the heated gas is sprayed out of the heat spray pipe 11 to heat the ice layer 8, so as to reduce the bonding strength of the ice blocks of the ice layer 8 and the upper end of the track 7 or even separate the two, which is beneficial to the subsequent crushing and complete cleaning of the ice layer 8.

[0080] It should be noted that the long spiral electric heating pipe can be electrically connected with a group of current regulators 501 in the automatic adjusting unit 5. When the ice layer 8 becomes thick, the mounting plate 201 rises, the power of the electric heating pipe becomes large, and the heating of the air is accelerated to quickly reduce the bonding of the ice blocks of the ice layer 8 and the upper end of the track 7. On the contrary, when the ice layer 8 becomes thin, the mounting plate 201 rises, the power of the electric heating pipe becomes small, and the power is saved. It can be self-adaptively adjusted, that is, it can satisfy the reduction of the bonding strength of the ice layer 8 and the track 7 and save the power.

[0081] Finally, it should be noted that the above only describes the preferred embodiments of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art will appreciate that the technical solutions described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalent features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
