[0036] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0037] The present invention relates to a mine-use endless rope rail-gripping magnetic braking tractor, which can make the magnetic braking block 12 be adsorbed on the rail by loosening or disconnecting the traction rope 3. Figures 1 to 4 As shown, an exemplary structure of the mining endless rope rail-holding magnetic brake tractor includes a car body 2 and a braking mechanism 1 provided on the car body 2, the braking mechanism 1 includes a rope supporting block 11 and a magnetic brake block 12, the bottom end of the rope supporting block 11 is elastically connected to the car body 2, and the top end supports and abuts the traction rope 3 on the car body 2, the rope supporting block 11 is provided with a pre-tightening force upward away from the car body 2, and a supporting portion for the magnetic brake block 12 to overlap is protruded from the side of the rope supporting block 11; the magnetic brake block 12 is located on the side where the supporting portion is provided with the rope supporting block 11, and one side of the magnetic brake block 12 is rotated around a first horizontal axis and connected to the car body 2, and the other side is overlapped and adapted with the supporting portion, the rope supporting block 11 has a first state under the pressure of the traction rope 3, and the magnetic brake block 12 in the first state is overlapped with the supporting portion, and the rope supporting block 11 also has a second state upward away from the car body 2, and the other side of the magnetic brake block 12 droops and is adsorbed on the steel rail supporting the car body 2.

[0038] Optionally, the specific implementation process of this embodiment is as follows:

[0039] When the mine endless rope track clamping magnetic suction braking traction vehicle in the application normally travels on the steel rail, the traction rope 3 on the vehicle body 2 is in a pulling state, and the traction rope 3 in this state always presses against the rope supporting block 11. The rope supporting block 11 can be overlapped with the magnetic suction braking block 12 in the above state, so that the magnetic suction braking block 12 is kept in the first state. When the traction rope 3 is loosened or disconnected, the elastic force received by the rope supporting block 11 is greater than the pressure of the traction rope 3. In this state, the rope supporting block 11 is displaced under the action of the elastic force, the overlap between the magnetic suction braking block 12 and the rope supporting block 11 is removed, the magnetic suction braking block 12 rotates around the first horizontal axis under the action of gravity, and then is adsorbed on the steel rail, and is turned into the second state of braking the vehicle body 2.

[0040] Compared with the prior art, the mine endless rope track clamping magnetic suction braking traction vehicle provided by the application has the beneficial effects that when the traction rope 3 is disconnected, the magnetic suction braking block 12 can be turned from the first state to the second state and tightly adsorbed on the side of the steel rail, and then the mine endless rope track clamping magnetic suction braking traction vehicle in the application can brake by using the friction between the magnetic suction braking block 12 and the steel rail to prevent the vehicle body 2 from sliding on the steel rail; in addition, when the magnetic suction braking block 12 is adsorbed on the steel rail, the stability of the vehicle body 2 can be increased to prevent the vehicle body 2 from overturning or derailing during braking; moreover, when the traction rope 3 is loosened, the magnetic suction braking block 12 in the application can be turned and attached to the steel rail under the action of gravity, without the need to set an additional power supply or driving device, so that the structure is simple and the maintenance is convenient.

[0041] In some embodiments, in order to facilitate the installation of the magnetic suction braking block 12 and the rope supporting block 11, as shown in Figure 1 and Figure 2 , the braking mechanism 1 further comprises a mounting support 13 arranged on the vehicle body 2 and an elastic connecting part 14 arranged on the mounting support 13. The bottom end of the rope supporting block 11 is connected to the mounting support 13 through the elastic connecting part 14, the elastic connecting part 14 is configured to have a pre-tightening force to make the rope supporting block 11 move upward away from the vehicle body 2, and the magnetic suction braking block 12 is rotationally connected to the mounting support 13 through a hinge shaft 122, and the axis of the hinge shaft 122 coincides with the first horizontal axis.

[0042] The beneficial effects of the embodiment are that the elastic connecting part 14, the rope supporting block 11 and the magnetic suction braking block 12 can be pre-integrated and assembled on the mounting support 13, and then the structures in the embodiment can be assembled at appropriate positions on the vehicle body 2 by using the connection between the mounting support 13 and the vehicle body 2, so that the assembly is convenient and the assembly efficiency is improved.

[0043] In the specific implementation, generally, the first horizontal axis is parallel to the length direction of the rail, the magnetic attraction braking block 12 is plate-shaped, and the long side thereof is rotationally connected to the mounting support 13 through the hinge shaft 122. When the magnetic attraction braking block 12 is disengaged from the lapping with the cable block 11, the magnetic attraction braking block 12 swings downward under the action of gravity with the first horizontal axis as the axis, and then is adsorbed on the rail, and uses the frictional resistance between the magnetic attraction braking block 12 and the rail to brake the vehicle body 2 on the rail. In addition, two magnetic attraction braking blocks 12 are generally arranged on the mounting support 13, and the two magnetic attraction braking blocks 12 are mirror-symmetrically arranged on the mounting support 13 with the cable block 11 as the center. The two sides of the cable block 11 are respectively lapped with the two magnetic attraction braking blocks 12. When the cable block 11 is bounced, the two magnetic attraction braking blocks 12 simultaneously swing downward and are respectively adsorbed on the two rails arranged correspondingly.

[0044] In some embodiments, the supporting part includes a connecting body connected with the cable block 11 and a first lapping protrusion 111 arranged on the connecting body. Corresponding to the first lapping protrusion 111, the magnetic attraction braking block 12 is formed with a second lapping protrusion 121, which can be lapped and matched with the first lapping protrusion 111. The lapped and matched parts of the first lapping protrusion 111 and the second lapping protrusion 121 are all formed with smooth curved surfaces.

[0045] The smooth curved surfaces formed at the lapped and matched parts of the first lapping protrusion 111 and the second lapping protrusion 121 make the process of disengaging the magnetic attraction braking block 12 from the cable block 11 more smooth. At the same time, the material of the cable block 11 is brass, so as to prevent the magnetic attraction braking block 12 from being adsorbed on the cable block 11.

[0046] In some embodiments, please refer to Figure 2 and Figure 3 The elastic connecting part 14 includes a mounting barrel 141 and a supporting spring 142. The mounting barrel 141 is fixedly arranged on the mounting support 13, and the axial direction of the mounting barrel 141 is parallel to the first vertical direction. The supporting spring 142 is coaxially arranged in the mounting barrel 141. The top end of the supporting spring 142 is connected with the cable block 11, and the bottom end of the supporting spring 142 is connected with the bottom plate of the mounting barrel 141. Corresponding to the supporting spring 142, the bottom of the cable block 11 is provided with a plug-in shaft 112, which is plug-in matched and clearance fitted with the supporting spring 142.

[0047] The elastic displacement of the cable block 11 along the low vertical direction can be realized through the extension and contraction of the spring in the mounting barrel 141, and the cable block 11 can always abut against the traction rope 3. When the traction rope 3 is loosened or disconnected, the cable block 11 can immediately pop up upward, and the lapping between the magnetic attraction braking block 12 and the cable block 11 is disengaged.

[0048] In the specific implementation of the present embodiment, preferably, the number of installation barrels 141 is two or more, and each installation barrel 141 is arranged on the installation support 13 along the length direction of the vehicle body 2, the number of supporting springs 142 corresponds to the number of installation barrels 141, and the insertion shaft 112 arranged on the rope supporting block 11 is inserted into each supporting spring 142 one by one, so that the elastic connection between the rope supporting block 11 and the installation support 13 is more stable and reliable.

[0049] Generally, the existing mine endless rope continuous traction vehicle adopts the way of winch winding and unwinding the traction rope 3 to drive the movement of the vehicle body 2 on the steel rail, so the connection between the traction rope 3 and the traction vehicle needs to be stable and reliable to prevent safety hazards caused by the loosening of the traction rope 3 during the movement of the vehicle body 2.

[0050] In view of the above problems, a solution is proposed to solve the problem that the connection between the existing traction rope 3 and the vehicle body 2 is not stable enough. In detail, as shown in Figure 1 In some embodiments, the mine endless rope rail clamping magnetic braking traction vehicle further comprises a rope pressing mechanism 4, the rope pressing mechanism 4 comprises a fixed plate 41, a pressing plate 42 and a lock catch 43, the fixed plate 41 is installed on the top of the vehicle body 2, and the plate surface of the fixed plate 41 is parallel to the horizontal plane, the plate thickness of the fixed plate 41 is greater than the diameter of the traction rope 3, one end of the traction rope 3 is wound around the outer periphery of the fixed plate 41 and connected to the vehicle body 2 through the lock catch 43, the pressing plate 42 is arranged on the upper plate surface of the fixed plate 41, the traction rope 3 is located between the lower plate surface of the pressing plate 42 and the vehicle body 2, and the other end of the traction rope 3 is connected with the driving winch. In the specific implementation, the part of the fixed plate 41 in contact with the rope pressing mechanism is formed with a rounded corner transition, so that the corner part of the fixed plate 41 is more rounded, preventing the fixed plate 41 from damaging the folded traction rope 3 due to the sharp corner part, and making the connection between the traction rope 3 and the fixed plate 41 more reasonable. Similarly, a U-shaped limiting groove matching the shape of the traction rope 3 is formed at the side edge of the fixed plate 41 in contact with the traction rope 3, so that when the traction rope 3 is wound around the fixed plate 41, the stress on the traction rope 3 is more uniform.

[0051] Compared with the prior art, the present embodiment has the beneficial effect that by folding and winding the traction rope 3 on the fixed plate 41, the tension can be uniformly distributed on the part where the traction rope 3 contacts the fixed plate 41, preventing the tension from being concentrated at a certain point of the traction rope 3, thereby helping to improve the technical problem that the existing traction rope 3 is loosened or even disconnected during the process of pulling the vehicle body 2 due to the unreasonable connection mode.

[0052] In some embodiments, please refer to Figure 2 and Figure 3The rope supporting block 11 is semi-cylindrical, and the axial direction of the rope supporting block 11 is parallel to the width direction of the vehicle body 2. Along the arc length direction of the cylindrical surface of the rope supporting block 11, a U-shaped groove 114 is formed on the cylindrical surface of the rope supporting block 11 to adapt to the outer periphery of the traction rope 3. The U-shaped groove 114 can limit the displacement of the traction rope 3 in the axial direction of the rope supporting block 11.

[0053] When the traction rope 3 is normally pulling the vehicle body 2, this embodiment can keep the traction rope 3 always pressed against the rope support block 11 by providing the U-shaped groove 114, thereby preventing the traction rope 3 from loosening from the rope support block 11 during the process of pulling the vehicle body 2 due to its own displacement.

[0054] In some embodiments, as Figure 1 As shown, the rope-holding mechanism 4 includes two sets of rope-holding assemblies symmetrically arranged on either side of the top of the vehicle body 2, with the brake mechanism 1 located between the two rope-holding assemblies. Each set of rope-holding assemblies includes a fixing plate 41, a pressure plate 42, and a lock 43. Each set of rope-holding assemblies corresponds one-to-one with a traction rope 3, and the outer peripheries of both traction ropes 3 press against the top of the rope-supporting block 11. In practice, the two sets of rope-holding assemblies are generally located adjacent to the front and rear ends of the vehicle body 2.

[0055] Compared with the prior art, since the two sets of traction ropes 3 press against the rope supporting block 11 at the same time, when the traction rope 3 on one side is loosened or disconnected, the rope supporting block 11 will not bounce upward, thereby preventing the magnetic brake block 12 from malfunctioning due to the loosening of the traction rope 3 on one side.

[0056] In some embodiments, track-clamping wheels 5 are provided on both sides of the bottom of the vehicle body 2. The distance between the two opposing track-clamping wheels 5 is greater than the rail gauge. In specific implementations, guard rails are generally installed on the outside of the track on curved roads and sections with heavy road conditions. The track-clamping wheels 5 in this embodiment can roll and fit on the guard rails to prevent the vehicle body 2 from overturning or derailing on curved roads and sections with complex road conditions.

[0057] In some embodiments, see Figure 4 The magnetic brake block 12 includes a shell 123 and a permanent magnet 124 disposed in the shell 123. One side of the shell 123 is rotatably connected to the mounting bracket 13, and the other side of the shell 123 can be overlapped with the supporting portion.

[0058] The housing 123 in this embodiment can protect the permanent magnet 124 and prevent the permanent magnet 124 from being damaged due to collision with the rails.

[0059] Preferably, see Figure 3The mounting support 13 comprises a rectangular mounting frame 131 and four limiting blocks 132 arranged at the corner portions of the mounting frame 131, the mounting frame 131 is assembled in the vehicle body 2 through the four limiting blocks 132, the above-mentioned hinged shaft 122 is rotationally connected to the limiting blocks 132, and the rope supporting block 11 is elastically connected to the mounting frame 131; meanwhile, in order to enable the magnetic attraction braking block 12 to be better attached to the steel rail when swinging to the second state, any one of the two limiting blocks 132 corresponding to the hinged shaft 122 is formed with an oblong hole 1321 which is adapted to the end portion of the hinged shaft 122, and the length direction of the oblong hole 1321 is parallel to the up-down direction.

[0060] In some embodiments, referring to Figure 2 and Figure 3 , the supporting portion is a copper member, and further, the supporting portion comprises a copper supporting plate 113 arranged on the rope supporting block 11, and the copper supporting plate 113 is located between the rope supporting block 11 and the magnetic attraction braking block 12, and the magnetic attraction braking block 12 can be overlapped on the copper supporting plate 113.

[0061] By arranging the copper supporting plate 113, the magnetic attraction braking block 12 can be prevented from being attracted to the rope supporting block 11, so that the process of the magnetic attraction braking block 12 from the first state to the second state is more smooth, of course, as to the specific material of the supporting portion, it can also be arranged as a non-magnetic medium such as polyurethane, which can meet the flame-retardant and anti-static requirements of the mining equipment, and the like are not listed here.

[0062] Preferably, the material of the mounting support 13 is copper alloy or aluminum alloy, so as to prevent the magnetic attraction braking block 12 from being unable to swing downward due to being attracted to the mounting support 13.

[0063] Optionally, in some embodiments, a magnetic sensing probe is arranged at the head and tail portions of the vehicle body 2, so as to sense the position of the vehicle relative to the steel rail.

[0064] In addition to the above-mentioned possible embodiments, in order to reduce the damage to both parties when the towing vehicle collides with other structures, referring to Figure 1 and Figure 5 , an energy absorption mechanism 6 is arranged at the head and tail of the towing vehicle, the energy absorption mechanism 6 comprises two buffer shells 61 connected to the head and tail of the vehicle body 2 respectively, an energy absorption box 62 is arranged in the buffer shell 61, the energy absorption box 62 is in the shape of a stepped conical frustum, and the axis of the energy absorption box 62 is parallel to the length direction of the vehicle body 2. In this way, when the vehicle body 2 is subjected to a collision, the collapsing deformation of the energy absorption box 62 and the buffer shell 61 can be utilized to prevent damage to the vehicle body 2 and other structures.

[0065] In summary, the mine-used endless rope track clamping magnetic suction braking tractor provided by the present application can brake by the friction between the magnetic suction braking block 12 and the steel rail to prevent the vehicle body 2 from sliding on the steel rail when the traction rope 3 is disconnected. Meanwhile, the magnetic suction braking block 12 can increase the stability of the vehicle body 2 when it is adsorbed to the steel rail, preventing the vehicle body 2 from overturning or derailing during braking. Furthermore, the magnetic suction braking block 12 can be turned over and attached to the steel rail by gravity when the traction rope 3 is loosened, without the need for an additional power supply or driving device, thus being simple in structure and convenient to maintain.

[0066] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application. 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.
