a first reversing frame 20 and a second reversing frame 20-1 are slidably connected below the vehicle body 14, two reversing columns 16 matched with the first hinge cage 4 and the second hinge cage 5 are elastically and slidably connected in the first reversing frame 20 and the second reversing frame 20-1, reversing rods 15 matched with the reversing columns 16 are slidably connected in the first reversing frame 20 and the second reversing frame 20-1, and two arc grooves used for driving the reversing columns 16 to longitudinally move are formed in the reversing rods 15; two stop levers for stopping the reversing lever 15 are fixedly connected below the vehicle body 14;
the first reversing frame 20 and the second reversing frame 20-1 are longitudinally connected with a first cross rod 13 in a sliding manner, and the first cross rod 13 is fixedly connected with a push plate 1; a first spring 21 is transversely connected on the first cross rod 13 in a sliding manner, and the first spring 21 is fixedly connected with the stop block 19; a clamping plate 31 is transversely connected below the first cross rod 13 in a sliding manner, and a pressing block 32 is connected in the clamping plate 31 in a sliding manner through a gas spring 34; a wedge 33 matched with the inclined hole in the pressing block 32 is elastically and slidably connected to the clamping plate 31.
When the invention is used, (the azimuth words used in the paragraph all take the azimuth of the first drawing as the reference), when the invention is in an initial state, the two push plates 1 are respectively clung to two sides of the vehicle body 14, the right reversing column 16 on the second reversing frame 20-1 is clung to the left side of the first hinge cage 4, and the left reversing column 16 is positioned behind the right end of the second hinge cage 5; a left reversing column 16 on the first reversing frame 20 is attached to the right side of the second hinge cage 5, and the right reversing column 16 is positioned behind the right end of the first hinge cage 4;
the motor 2 is started, the chain 11 drives the chain wheel 12 to rotate when the motor 2 rotates, so that the chain wheel 12 is driven to rotate to drive the rear wheel of the inspection vehicle fixedly connected with the chain wheel 12 to rotate, and the inspection vehicle is driven to move forwards;
meanwhile, two output ends of the motor 2 are connected with a first transmission shaft 3 through a first belt 7, the first transmission shaft 3 rotates to drive a first hinge cage 4 and a second hinge cage 5 which are fixedly connected to the first transmission shaft 3 to synchronously rotate, and the first hinge cage 4 and the second hinge cage 5 are designed in a symmetrical mode, so that snow between the two snow squeezing boxes 9 can be respectively pushed into the snow squeezing boxes 9 on two sides when the first hinge cage 4 and the second hinge cage 5 synchronously rotate, and the snow can be sprayed to two sides of a track through snow discharge pipes 8 on the snow squeezing boxes 9;
in addition, the first hinging cage 4 rotates and can move towards the right side by extruding the reversing column 16 on the right side of the second reversing frame 20-1, the first cross rod 13 is longitudinally and slidably connected to the second reversing frame 20-1, so that the second reversing frame 20-1 can push the first cross rod 13 to move towards the right side while moving towards the right side, and the first cross rod 13 is fixedly connected with the push plate 1, so that the second reversing frame 20-1 can move towards the right side by driving the push plate 1 to move towards the right side through the first cross rod 13, so that the accumulated snow sprayed by the snow discharge pipe 8 is pushed towards the outer side of the track through the push plate 1, and the accumulated snow on the outer side of the track is firmly extruded to prevent the accumulated snow from collapsing and falls onto the track from new time;
because the wedge 33 is elastically connected in the pressing block 32 in a sliding way, when the push plate 1 longitudinally connected with the second reversing frame 20-1 in a sliding way moves towards the right side of the outer side of the track, the wedge 33 will lose the blocking of the push plate 1 and separate from the pressing block 32 under the action of elastic force, because the pressing block 32 is slidably connected with the clamping plate 31 by the gas spring 34, after the wedge 33 is separated from the pressing block 32, the pressing block 32 moves downwards under the action of the gas spring 34 under the condition of losing the limit of the wedge 33, so that the pressing block 32 is in close contact with the rail by the gas spring 34, thereby generating a great friction force between the pressing block 32 and the rail, so that the clamping plate 31 is locked on the track, and because the clamping plate 31 is transversely and slidably connected with the first cross rod 13, therefore, when the push plate 1 is separated from the wedge 33 and continues to move towards the outer side of the track, the first cross rod 13 will not move forwards with the patrol car under the limit of the clamping plate 31; when the second reversing frame 20-1 moves to the right limit position under the driving of the first hinge cage 4, the right end of the reversing rod 15 in the second reversing frame 20-1 contacts with the stop block 19 fixedly connected to the right side of the vehicle body 14, and is extruded into the second reversing frame 20-1 in the process of moving to the right side along with the second reversing frame 20-1, when the reversing rod 15 in the second reversing frame 20-1 is extruded, the reversing rod moves to the left relative to the second reversing frame 20-1, the reversing column 16 on the left side of the second reversing frame 20-1 is separated from the arc groove on the reversing rod 15, so that the reversing column 16 on the left side of the second reversing frame 20-1 is jacked, the reversing column 16 on the left side of the second reversing frame 20-1 is inserted into the right side in the second hinge cage 5, and the reversing column 16 on the right side of the second reversing frame 20-1 enters the arc groove on the right side of the reversing rod 15 under the action of elasticity, so that the right reversing column 16 on the second reversing frame 20-1 is separated from the first hinging cage 4; then the second reversing frame 20-1 is driven by the second hinge cage 5 to move inwards, so that the first cross rod 13 is driven to do reset motion towards the inside of the track, and the push plate 1 is driven by the first cross rod 13 to do reset motion towards the inside of the track; because the push plate 1 is transversely and slidably connected with the clamping plate 31, the clamping plate 31 is locked on the track at the moment, the patrol vehicle moves forwards for a certain distance relative to the push plate 1 and the clamping plate 31 in the inward movement process of the push plate 1 (the push plate is controlled by the clamping plate to be prevented from synchronously moving along with the vehicle body when retracting inwards, so that the accumulated snow is prevented from being pushed back to the side of the track in the synchronous movement process of the vehicle body);
therefore, when the push plate 1 moves to the initial position along with the second reversing frame 20-1, the push plate 1 can push the wedge 33 to move inwards, so that the press block 32 overcomes the elastic force of the gas spring 34 to move upwards by extruding the wedge 33, the clamp plate 31 is not in close contact with the rail any more, and the friction force between the clamp plate 31 and the rail is eliminated; since the first cross bar 13 is transversely and slidably connected with the first spring 21 fixedly connected with the right side stop block 19, when the push plate 1 is completely contracted, the push plate 1 can move forwards under the action of the first spring 21, so as to restore to the initial position; under the drive of the first hinging cage 4 and the second hinging cage 5, the second reversing frame 20-1 can drive the push plate 1 to transversely reciprocate; thereby the accumulated snow on the right side is squeezed tightly, and the accumulated snow is prevented from sliding downwards;
similarly, the motion trajectories of the first reversing frame 20 on the left side and the second reversing frame 20-1 on the right side are completely consistent, and are not described herein again;
through the cooperative work of the first hinge cage 4 and the second hinge cage 5, the accumulated snow in the rail is sprayed to the two sides of the rail, and meanwhile, the first hinge cage 4 and the second hinge cage 5 synchronously rotate to enable the push plate 1 connected with the first reversing frame 20 and the second reversing frame 20-1 to transversely reciprocate, so that the accumulated snow on the two sides of the rail is extruded and compacted, and the accumulated snow is prevented from collapsing and reentering the rail.
As a further scheme of the invention, a supporting device 30 is fixedly connected below the vehicle body 14, the supporting device 30 is rotatably connected with two friction wheels 17 matched with the first reversing frame 20 and the second reversing frame 20-1, and the contact surfaces of the first reversing frame 20 and the second reversing frame 20-1 and the friction wheels 17 are rough surfaces; the two friction wheels 17 are fixedly connected with a rotary table 28 through a rotary shaft, a stop pillar 27 is fixedly connected on the rotary table 28, two guide rods 29 are slidably connected on the supporting device 30, and the two guide rods 29 are fixedly connected with a waist ring 26 matched with the stop pillar 27; the two sides of the vehicle body 14 are fixedly connected with second mounting frames 25, the two second mounting frames 25 are hinged with the scraping plate 18, the hinged point of the scraping plate 18 and the second mounting frames 25 is the middle part of the scraping plate 18, and the two guide rods 29 are hinged with the top part of the scraping plate 18; when in work: the accumulated snow on the track is difficult to be removed completely by the first hinge cage 4 and the second hinge cage 5, but the remained accumulated snow can be frozen after being untreated for a long time, so that the smooth running of the train is threatened; therefore, the snow cover is expected to be cleaned up on the track; when the first reversing frame 20 and the second reversing frame 20-1 reciprocate, the two friction wheels 17 attached to the first reversing frame 20 and the second reversing frame 20-1 are driven to rotate, the friction wheels 17 rotate to drive the rotary table 28 fixedly connected with the friction wheels to rotate, the rotary table 28 rotates to drive the stop posts 27 fixedly connected to the rotary table 28 to synchronously rotate, and the stop posts 27 synchronously rotate along with the rotary table 28 to drive the guide rods 29 which are matched with the stop posts and transversely connected to the support device 30 in a sliding manner to reciprocate; since the middle portion of the scraper 18 is hinged to the second mounting frame 25 fixedly connected to the vehicle body 14, and the guide rod 29 is hinged to the top portion of the scraper 18, the scraper 18 is driven to swing back and forth around the hinged point of the scraper 18 and the second mounting frame 25 during the reciprocating motion of the guide rod 29, so that snow on the track can be cleaned.
As a further scheme of the present invention, two guide rods 29 are fixedly connected with a first sliding plate 23 and a second sliding plate 24 respectively, the rear end of the vehicle body 14 is fixedly connected with the storage box 10, the first sliding plate 23 and the second sliding plate 24 are both slidably connected to the storage box 10, a large number of through holes are respectively formed in the first sliding plate 23 and the second sliding plate 24, and the through holes in the first sliding plate 23 and the second sliding plate 24 are staggered; when in work: to prevent snow from falling again on the track and accumulating, it is desirable to be able to sprinkle industrial salt on the track to prevent snow from falling again; when the two first connecting rods 22 fixedly connected to the guide rod 29 reciprocate along with the guide rod 29, the two first connecting rods 22 drive the first sliding plate 23 and the second sliding plate 24 fixedly connected to the two first connecting rods 22 to move synchronously; since the first and second sliding plates 23 and 24 are slidably coupled to the bottom of the storage case 10, the first and second sliding plates 23 and 24 reciprocate toward and away from each other while reciprocating along the two guide rods 29, respectively; so that the through holes of the first and second sliding plates 23 and 24 are moved in a staggered manner, and the industrial salt in the storage box 10 is uniformly scattered on the track, thereby preventing accumulation of accumulated snow.
As a further scheme of the invention, a storage box 10 is fixedly connected to the rear part of the vehicle body 14, and a closable feed opening is arranged at the upper part of the storage box 10. .
As a further aspect of the present invention, lubricating oil is applied between the clamping plate 31 and the first cross bar 13 and between the cross bar and the first spring 21.
The working principle is as follows: when the invention is used, in an initial state, the two push plates 1 are respectively clung to two sides of the vehicle body 14, the right reversing column 16 on the second reversing frame 20-1 is clung to the left side of the first hinge cage 4, and the left reversing column 16 is positioned behind the right end of the second hinge cage 5; a left reversing column 16 on the first reversing frame 20 is attached to the right side of the second hinge cage 5, and the right reversing column 16 is positioned behind the right end of the first hinge cage 4;
the motor 2 is started, the chain 11 drives the chain wheel 12 to rotate when the motor 2 rotates, so that the chain wheel 12 is driven to rotate to drive the rear wheel of the inspection vehicle fixedly connected with the chain wheel 12 to rotate, and the inspection vehicle is driven to move forwards;
meanwhile, two output ends of the motor 2 are connected with a first transmission shaft 3 through a first belt 7, the first transmission shaft 3 rotates to drive a first hinge cage 4 and a second hinge cage 5 which are fixedly connected to the first transmission shaft 3 to synchronously rotate, and the first hinge cage 4 and the second hinge cage 5 are designed in a symmetrical mode, so that snow between the two snow squeezing boxes 9 can be respectively pushed into the snow squeezing boxes 9 on two sides when the first hinge cage 4 and the second hinge cage 5 synchronously rotate, and the snow can be sprayed to two sides of a track through snow discharge pipes 8 on the snow squeezing boxes 9;
in addition, the first hinging cage 4 rotates and can move towards the right side by extruding the reversing column 16 on the right side of the second reversing frame 20-1, the first cross rod 13 is longitudinally and slidably connected to the second reversing frame 20-1, so that the second reversing frame 20-1 can push the first cross rod 13 to move towards the right side while moving towards the right side, and the first cross rod 13 is fixedly connected with the push plate 1, so that the second reversing frame 20-1 can move towards the right side by driving the push plate 1 to move towards the right side through the first cross rod 13, so that the accumulated snow sprayed by the snow discharge pipe 8 is pushed towards the outer side of the track through the push plate 1, and the accumulated snow on the outer side of the track is firmly extruded to prevent the accumulated snow from collapsing and falls onto the track from new time;
because the wedge 33 is elastically connected in the pressing block 32 in a sliding way, when the push plate 1 longitudinally connected with the second reversing frame 20-1 in a sliding way moves towards the right side of the outer side of the track, the wedge 33 will lose the blocking of the push plate 1 and separate from the pressing block 32 under the action of elastic force, because the pressing block 32 is slidably connected with the clamping plate 31 by the gas spring 34, after the wedge 33 is separated from the pressing block 32, the pressing block 32 moves downwards under the action of the gas spring 34 under the condition of losing the limit of the wedge 33, so that the pressing block 32 is in close contact with the rail by the gas spring 34, thereby generating a great friction force between the pressing block 32 and the rail, so that the clamping plate 31 is locked on the track, and because the clamping plate 31 is transversely and slidably connected with the first cross rod 13, therefore, when the push plate 1 is separated from the wedge 33 and continues to move towards the outer side of the track, the first cross rod 13 will not move forwards with the patrol car under the limit of the clamping plate 31; when the second reversing frame 20-1 moves to the right limit position under the driving of the first hinge cage 4, the right end of the reversing rod 15 in the second reversing frame 20-1 contacts with the stop block 19 fixedly connected to the right side of the vehicle body 14, and is extruded into the second reversing frame 20-1 in the process of moving to the right side along with the second reversing frame 20-1, when the reversing rod 15 in the second reversing frame 20-1 is extruded, the reversing rod moves to the left relative to the second reversing frame 20-1, the reversing column 16 on the left side of the second reversing frame 20-1 is separated from the arc groove on the reversing rod 15, so that the reversing column 16 on the left side of the second reversing frame 20-1 is jacked, the reversing column 16 on the left side of the second reversing frame 20-1 is inserted into the right side in the second hinge cage 5, and the reversing column 16 on the right side of the second reversing frame 20-1 enters the arc groove on the right side of the reversing rod 15 under the action of elasticity, so that the right reversing column 16 on the second reversing frame 20-1 is separated from the first hinging cage 4; then the second reversing frame 20-1 is driven by the second hinge cage 5 to move inwards, so that the first cross rod 13 is driven to do reset motion towards the inside of the track, and the push plate 1 is driven by the first cross rod 13 to do reset motion towards the inside of the track; because the push plate 1 is transversely connected with the clamping plate 31 in a sliding manner, the clamping plate 31 is locked on the track at the moment, and the patrol vehicle moves forwards for a certain distance relative to the push plate 1 and the clamping plate 31 in the inward movement process of the push plate 1;
therefore, when the push plate 1 moves to the initial position along with the second reversing frame 20-1, the push plate 1 can push the wedge 33 to move inwards, so that the press block 32 overcomes the elastic force of the gas spring 34 to move upwards by extruding the wedge 33, the clamp plate 31 is not in close contact with the rail any more, and the friction force between the clamp plate 31 and the rail is eliminated; since the first cross bar 13 is transversely and slidably connected with the first spring 21 fixedly connected with the right side stop block 19, when the push plate 1 is completely contracted, the push plate 1 can move forwards under the action of the first spring 21, so as to restore to the initial position; under the drive of the first hinging cage 4 and the second hinging cage 5, the second reversing frame 20-1 can drive the push plate 1 to transversely reciprocate; thereby the accumulated snow on the right side is squeezed tightly, and the accumulated snow is prevented from sliding downwards;
similarly, the motion trajectories of the first reversing frame 20 on the left side and the second reversing frame 20-1 on the right side are completely consistent, and are not described herein again;
through the cooperative work of the first hinge cage 4 and the second hinge cage 5, the accumulated snow in the rail is sprayed to the two sides of the rail, and meanwhile, the first hinge cage 4 and the second hinge cage 5 synchronously rotate to enable the push plate 1 connected with the first reversing frame 20 and the second reversing frame 20-1 to transversely reciprocate, so that the accumulated snow on the two sides of the rail is extruded and compacted, and the accumulated snow is prevented from collapsing and reentering the rail.
