Detailed Description
The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Embodiment one: referring to fig. 1-6: the underground coal mine steel wire rope traction rail car comprises a car body 1, wherein the bottom of the car body 1 is fixedly connected with a bottom plate 2, four moving assemblies 3 are arranged at the bottom of the bottom plate 2, a first braking mechanism 4 is arranged at the bottom of the bottom plate 2, and a second braking mechanism 5 is arranged at one side of the first braking mechanism 4;
The first braking mechanism 4 comprises a first mounting frame 41 and a rotating sleeve 42, a first rotating rod 43 is arranged on the inner side of the rotating sleeve 42, two protruding blocks 432 are symmetrically and fixedly connected to the outer wall of the middle part of the first rotating rod 43, a clamping groove 421 is formed in the rotating sleeve 42, the rotating sleeve 42 is in sliding connection with the first rotating rod 43, the protruding blocks 432 are spliced with the clamping groove 421, a limiting groove 48 is formed in the outer surface of one end of the rotating sleeve 42, first swinging frames 45 are arranged on two sides of the rotating sleeve 42, a second rotating rod 46 is fixedly connected to the middle part of the first swinging frames 45, a pressing block 47 is fixedly connected to one side of the bottom end of each first swinging frame 45, a pressing wheel 451 is rotatably connected to the inner side of the top end of each first swinging frame 45, a fixing rod 452 is fixedly connected to one side of the middle part of each first swinging frame 45, a tension spring 49 is arranged on one side of each rotating sleeve 42, two ends of each tension spring 49 are respectively clamped with the two fixing rods 452, and a driving gear 431 is fixedly connected to one end of each first swinging frame 43.
In this embodiment, when the driving gear 431 rotates during braking, it drives the first rotating lever 43 to rotate together. At this time, the protrusion 432 in the middle of the first rotating rod 43 will cooperate with the locking slot 421 to apply a force to the rotating sleeve 42 during the rotation process, so that the rotating sleeve 42 starts to rotate. Since the driving gear 431 rotates together with the first rotating lever 43 and the rotating sleeve 42, it applies a force to the pressing wheels 451 on both sides as the rotating sleeve 42 rotates. This causes the pressing wheel 451 to transmit the force to the first swing frame 45, causing the first swing frame 45 to start rotating about the second rotation lever 46. Along with the rotation of the first swinging frames 45, the rotating sleeve 42 also gradually expands the top ends of the two first swinging frames 45, and the bottom ends gradually gathers together, so as to drive the extrusion block 47 to approach the track, and realize the braking effect.
Further, the flat structure of the rotating sleeve 42 enables it to gradually control the swing of the first swing frame 45 by its own rotation. Due to the different widths of the two ends of the rotating sleeve 42, the contact positions between the extrusion wheel 451 and the outer wall of the rotating sleeve 42 are different, and the rotating angle of the first swinging frame 45 is further affected. Thus, when the adjustment lever 44 is rotated by the handle 441, the movement of the push plate 442 can be adjusted to act on the rotation sleeve 42 in cooperation with the limit groove 48. This not only pushes the rotating sleeve 42 but also pulls the rotating sleeve 42 to slide on the surface of the first rotating lever 43.
Although the rotating sleeve 42 slides on the surface of the first rotating lever 43, it rotates together with the first rotating lever 43 when it rotates due to the presence of the catching groove 421 and the projection 432. The rotation of the rotating sleeve 42 can be controlled by the design, and the swinging angles of the two first swinging frames 45 can be adjusted, so that the extrusion force when the extrusion block 47 is in contact with the rail is changed. The squeeze block 47 maintains its braking ability even if it wears during long braking.
Embodiment two: as shown in fig. 6-9, the second braking mechanism 5 includes a second mounting frame 52 and a half gear 55, a support frame 54 is fixedly connected to the bottom of the second mounting frame 52, a third rotating rod 551 is fixedly connected to the middle of the half gear 55, and two ends of the third rotating rod 551 are both rotatably connected to the support frame 54. The inboard of second mounting bracket 52 is provided with lifter plate 53, and the pneumatic cylinder 51 is installed at second mounting bracket 52 top, pneumatic cylinder 51 output and lifter plate 53 top fixed connection, lifter plate 53 bottom fixedly connected with first rack 57, and first rack 57 both sides all meshing are connected with drive gear 56, and drive gear 56 rotates with pneumatic cylinder 51 inner wall and is connected. The half gear 55 is meshed with the transmission gear 56, the bottom end of the half gear 55 is fixedly connected with a second swinging frame 552, and one side of the top end of the lifting plate 53 is fixedly connected with a limiting rod 531. The two sides of the top end of the lifting plate 53 are fixedly connected with connecting rods 583, the second installation frame 52 is provided with a control frame 58, the top end of the control frame 58 is fixedly connected with the two connecting rods 583, and guide grooves 581 are formed in the two sides of the control frame 58.
In this embodiment, when the hydraulic cylinder 51 is operated, it pushes the lifting plate 53 up and down in the second mounting frame 52 by the generated linear motion. This movement not only directly affects the position of the lifting plate 53, but also drives the lifting movement of the first rack 57 through its connection to the first rack 57.
As the first rack 57 is lifted, it engages with the two transfer gears 56, thereby driving the two gears to rotate in opposite directions. This design enables the transfer gear 56 to effectively convert the linear motion of the first rack 57 into rotational motion of its own. The interaction between the transfer gear 56 and the half gear 55 is another core part of the brake system. The half gear 55 is fixed in place by the third rotary bar 551, which drives the half gear 55 to rotate by the interaction force between the gears when the transmission gear 56 rotates.
The rotation directions of the two half gears 55 are opposite, and this design enables the two second swing frames 552 to swing toward each other during braking. This opposite swing brings the pressing pads 553 of the two second swing frames 552 gradually closer to the rail, enhancing a braking effect by increasing a contact area and friction with the rail. At the same time, the pressing pad 553 at the bottom end of the first rack 57 moves downward, increasing the contact force with the rail, further improving the braking effect.
By the friction force between the three pressing pads 553 and the rail, a stable braking effect can be maintained even in the case where the vehicle body 1 is inclined, effectively avoiding the sliding of the vehicle body 1.
Embodiment III: according to fig. 3, 4,7 and 8, the two ends of the first rotating rod 43 are both rotatably connected with the first mounting frame 41, the top of the first mounting frame 41 is fixedly connected with the bottom of the bottom plate 2, and one end of the second rotating rod 46 is rotatably connected with the first mounting frame 41. The regulation pole 44 is installed to first mounting bracket 41 one side, and regulation pole 44 one end fixedly connected with push plate 442, push plate 442 and spacing groove 48 joint, regulation pole 44 one end runs through first mounting bracket 41, and regulation pole 44 and first mounting bracket 41 threaded connection, regulation pole 44 one end fixedly connected with handle 441. Two second swing frames 552 are all fixedly connected with extrusion pad 553 in opposite ends, and lifter plate 53 bottom fixedly connected with extrusion pad 553, and spacing hole 521 has been seted up to second mounting bracket 52 lateral wall, and spacing hole 521 inside sliding connection has gag lever post 531, and gag lever post 531 one end fixedly connected with limiting plate 532, and limiting plate 532 diameter is greater than spacing hole 521 width. A second rack 582 is fixedly connected to one side of the inner cavity of the control frame 58, the second rack 582 is in meshed connection with the driving gear 431, a limiting frame 59 is slidably connected to the inside of the guide groove 581, and one end of the limiting frame 59 is fixedly connected with the hydraulic cylinder 51. The side wall of the second mounting frame 52 is fixedly connected with a fixed block 522, and the fixed block 522 is fixedly connected with the side wall of the first mounting frame 41.
In the present embodiment, the lifter plate 53 starts its stable downward movement with the actuation of the hydraulic cylinder 51. The sliding of the limit lever 531 in the limit hole 521 ensures that the moving track of the lifting plate 53 is always kept straight. The restraint effect of the limiting plate 532 ensures that the lifting plate 53 does not deviate from the direction when moving, and the stability of the whole system is ensured.
The movement of the lifter plate 53 is not isolated and it further moves the control frame 58 up and down through the connection to the connecting rod 583. The control rack 58 causes the rotation of the driving gear 431 by the interaction of the second rack 582 with the driving gear 431. The rotation of the driving gear 431 drives the rotation of the first rotating lever 43, and thus the two first swinging frames 45 start swinging motion centering on the second rotating lever 46 under the cooperative action of the rotating sleeve 42. When the two first swing frames 45 are in contact with the rail through the pressing block 47, they achieve a braking effect. At the same time, three squeeze pads 553 are also in contact with the rail, thereby enhancing overall braking effectiveness. Not only improves the braking effect, but also enhances the reliability of the system.
The tension spring 49 plays a vital role in the swinging of the two first swinging frames 45. It urges the two first swing frames 45 toward each other under the guide of the fixing lever 452 by means of the elastic action thereof. This design is such that when the pinch roller 451 contacts the flat surface of the rotator cuff 42, it will move away from the rail under the tension of the tension spring 49. This movement away from the track not only avoids unnecessary friction and wear, but also ensures the stability and effectiveness of the braking system.
The application method and the working principle of the device are as follows: when the lifting plate 53 starts to move downward under the driving of the hydraulic cylinder 51, it not only performs normal lifting movement inside the hydraulic cylinder 51, but also drives the limit lever 531 to slide in the limit hole 521. The limiting hole 521 ensures stable movement of the lifting plate 53 in a straight direction due to the limitation of the limiting plate 532, thereby preventing skew or offset thereof.
With the lifting movement of the lifting plate 53, the first rack 57 also moves synchronously, and thus applies an engaging force to the two transfer gears 56, causing them to start rotating in opposite directions. The rotation of the transmission gear 56 generates a force on the half gear 55, causing the half gear 55 to rotate centering on the third rotation lever 551. The rotation directions of the two half gears 55 are opposite, and the pressing pads 553 are driven by the second swing frame 552 to gradually approach the track, so as to realize a braking effect.
When the pressing pads 553 at opposite ends of the two second swing frames 552 approach the rails, the pressing pads 553 at the bottom ends of the first racks 57 also move downward, enhancing the braking effect. This ensures that the vehicle body 1 can achieve stable braking in both a fast running or tilting state, preventing slipping.
In addition, the movement of the lifting plate 53 also drives the connecting rod 583 to lift and lower the control frame 58. During the lifting, the second rack 582 applies a force to the driving gear 431 to rotate it. Rotation of the driving gear 431 rotates the first rotating lever 43. When the driving gear 431 rotates, the protrusion 432 cooperates with the engagement groove 421 to apply a force to the rotation sleeve 42, so that the rotation sleeve starts to rotate. Since the driving gear 431 rotates simultaneously with the first rotating lever 43 and the rotating sleeve 42, the rotating sleeve 42 applies a force to the pressing wheels 451 on both sides, and thus transmits to the first swing frame 45 to start rotation. Along with the rotation of the first swinging frames 45, the rotating sleeve 42 gradually enables the top ends of the two first swinging frames 45 to be unfolded, the bottom ends of the two first swinging frames are gathered, the extrusion blocks 47 are driven to approach the track, and braking is achieved.
The flat structure of the rotating sleeve 42 allows it to control the swing of the first swing frame 45 by rotating itself. The different widths of the two ends of the rotating sleeve 42 cause the contact position of the pressing wheel 451 and the pressing wheel to be different, thereby affecting the rotation angle of the first swing frame 45. By rotating the adjustment lever 44, the push plate 442 is controlled to move, thereby exerting an action on the rotating sleeve 42 to slide on the surface of the first rotating lever 43. Although the rotating sleeve 42 is slidable, it follows rotation as the first rotating lever 43 rotates, thereby controlling the swing angle of the first swing frame 45, changing the contact pressing force of the pressing block 47 with the rail, and securing the braking ability after a long time braking.
When the two first swing frames 45 swing, the tension spring 49 provides a tension force to bring the two first swing frames 45 toward each other under the guide of the fixing lever 452. Therefore, when the pinch roller 451 contacts the off-plane surface of the rotating sleeve 42, it moves away from the rail by the tension spring 49, ensuring stability and effectiveness of braking.
