Description

Technical Field

[0001] The invention relates to the technical field of mountain transportation, in particular to a mountain double-track transport vehicle used for transporting mountain materials. Background Art

[0002] The electric mountain double-track transport vehicle is a type of transportation equipment used in areas with high, steep mountains, many bends, loose gravel and mountain forests, and dense bamboo and wood forests. It is impossible to open roads for mountain vehicles. It changes the traditional modes of transportation such as manual shoulder-carrying and animal transportation, and improves the mechanization, efficiency and cost-reduction of transportation operations. Through the double-track design, this type of vehicle can stably shuttle between steep slopes and gullies, effectively expanding the coverage of material transportation. It is particularly suitable for industries that require frequent operations in mountains, such as mining, forestry and agriculture.

[0003] However, although mountain double-track transport vehicles have shown significant advantages in improving transportation efficiency, they still face challenges in dealing with diverse and non-standardized goods. In the existing technology, the fixing devices of the cargo hold are often fixed or of a single size, which makes it difficult to flexibly adapt to goods of different shapes, sizes and weights. This limitation not only limits the scope of application of the transport vehicle, but also increases the risk of damage or falling of goods during transportation, especially in mountainous environments, where vehicle vibration caused by undulating terrain exacerbates this problem.

DETAILED DESCRIPTION

[0016] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0017] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0018] See also Figure 1-7 , the present invention provides a technical solution: A mountain double-track transport vehicle for transporting mountain materials, comprising a cargo hold 1, double tracks 2, and a transport vehicle body 3. The double tracks 2 are laid on the mountain surface, and the transport vehicle body 3 can move along the top of the double tracks 2. The cargo hold 1 is fixed to the top of the transport vehicle body 3 and is used to transport goods. The inner wall of the cargo hold 1 is sequentially provided with a first binding mechanism 4, a second binding mechanism 5, and a third binding mechanism 6 for fixing goods from top to bottom. The first binding mechanism 4 can move according to the center of gravity offset of the goods, and cooperates with the second binding mechanism 5 and the third binding mechanism 6 to adaptively bind and fix goods of unequal width and irregular shape from top to bottom. The first binding mechanism 4 includes a binding belt 41 and a fixed bin 42. The goods are bound by the binding belt 41. The end b of the binding belt 41 is fixed in the inner cavity of the fixed bin 42. The two sides of the fixed bin 42 are respectively provided with movable channels 421. The end a of the binding belt 41 passes through the fixed bin 42 through the movable channels 421. The end a of the binding belt 41 is rolled up on the outside of the winding roller 43. The bottom of the winding roller 43 is provided with a driving motor 431 for driving the winding roller 43 to rotate. A self-locking device 46 is provided on the inner side of the fixed compartment 42 , and the self-locking device 46 is used to fix the inner diameter of the binding belt 41 when the binding belt 41 is used to tighten the cargo.

[0019] In this embodiment, please refer to Figure 3 A rack 47 is provided on the side where the fixed bin 42 contacts the inner wall of the cargo bin 1, and a servo motor 44 is also provided in the inner wall of the cargo bin 1. A gear 45 is provided at the output end of the servo motor 44, and the outer edge of the gear 45 meshes with one side of the rack 47. A load-bearing plate 13 for supporting the cargo is provided at the bottom of the inner cavity of the cargo bin 1, and an inclination sensor 15 is provided inside the load-bearing plate 13. In this embodiment, when the transport vehicle goes uphill or downhill, the center of gravity of the cargo tilts, and under the action of pressure, the load-bearing plate 13 tilts. The inclination direction and angle of the load-bearing plate 13 are detected by the inclination sensor 15, and the servo motor 44 gives power to control the rotation of the gear 45. Since the rack 47 and the gear 45 mesh with each other, the fixed bin 42 is driven to move along the inner wall of the cargo bin 1. Since the strap 41 is tied to the top of the cargo, the strap 41 is driven to move through the fixed bin 42, which can be used to correct the center of gravity of the cargo and prevent the cargo from tilting. This arrangement can prevent the cargo from tilting and causing spillage or deformation when the transport vehicle is transporting fluids and liquids.

[0020] In this embodiment, please refer to Figure 4 The self-locking device 46 includes a pressing block 461, and a linkage plate 464 is provided on one side of the pressing block 461. The linkage plate 464 is located inside the fixed bin 42 and on one side of the movable channel 421. The corresponding surfaces of the strap 41 and the linkage plate 464 are respectively provided with a locking groove 411 and a locking block 465. The locking groove 411 and the locking block 465 are adapted to each other. A spring 467 is provided at one end of the linkage plate 464, and a fixing block 466 is provided at one end of the spring 467. In this embodiment, when the strap 41 is used to tie up the cargo, the pressing block 461 is squeezed toward When the linkage plate 464 moves backward, the locking block 465 contacts one side of the strap 41, so that the locking block 465 and the locking groove 411 provide resistance, so that the inner diameter of the strap 41 is fixed, thereby preventing the strap 41 from loosening or falling off during transportation of the goods. At the same time, when the goods are taken out, the spring 467 loses pressure and returns to its original state, and the locking block 465 returns to its original position under the action of the elastic force.

[0021] In this embodiment, please refer to Figure 5When the winding roller 43 retracts and releases the strap 41, the interlocking roller 422 rotates, and the interlocking roller 422 is movably connected to the inner cavity of the fixed bin 42. A torsion spring 423 is provided on the top of the interlocking roller 422. In this embodiment, when the winding roller 43 rewinds the strap 41, the inner diameter of the strap 41 gradually becomes smaller, and the interlocking roller 422 also rotates accordingly. The rotation of the interlocking roller 422 drives the torsion spring 423 to deform. When the driving motor 431 stops driving the winding roller 43 and the self-locking device 46 stops fixing the strap 41, the torsion spring 423 loses pressure and returns to its original state, thereby causing the interlocking roller 422 to rotate and causing the inner diameter of the strap 41 to return to its original size, so that the strap 41 can continue to bind the goods next time.

[0022] In this embodiment, please refer to Figure 6 , an unlocking seat 4641 is provided at the top of the linkage plate 464, and an unlocking plate 4642 is fixedly connected to the bottom of the unlocking seat 4641, and one side of the unlocking plate 4642 is fixedly connected to the locking block 465, and a push rod 463 is provided on the top of the unlocking seat 4641 for fixing it to the top of the linkage plate 464. In this embodiment, when the goods are untied, or the goods are tied too tightly, the pressing block 461 is squeezed so that the inner diameter length of the binding strap 41 cannot be restored, by unscrewing the bolt 4643, the position of the unlocking seat 4641 is moved, and the locking block 465 moves backward and stops contacting the locking groove 411. At this time, under the rotation of the linkage roller 422, the inner diameter of the binding strap 41 can be quickly restored to untie the goods.

[0023] In this embodiment, please refer to Figure 4 Two expansion plates 462 are provided on one side of the pressure block 461, and the b end of the strap 41 passes through the gap between the two expansion plates 462. A push rod 463 is provided on one side of the expansion plate 462 and is fixedly connected to the linkage plate 464 through the push rod 463. In this embodiment, the linkage plate 464 bypasses the b end of the strap 41 by providing the expansion plate 462 and the push rod 463, so that the linkage plate 464 can be pushed to enable the locking block 465 to lock the locking groove 411.

[0024] In this embodiment, please refer to Figure 7 The inner wall of the cargo hold 1 is provided with a plurality of mounting grooves 11, and the plurality of mounting grooves 11 are respectively used for installing binding mechanisms. The inner wall of the mounting groove 11 located at the top of the inner wall of the cargo hold 1 is also provided with a slide groove 12. In this embodiment, by providing a plurality of mounting grooves 11 for installing a plurality of binding mechanisms, the transport vehicle can choose to install a plurality of binding mechanisms according to the steepness of the mountain, thereby increasing the stability of cargo transportation. By providing a slide groove 12, a movable space is given to the fixed warehouse 42, which is used to move the top of the cargo to adjust the center of gravity of the cargo.

[0025] In this embodiment, please refer to Figure 7 A rubber pad 14 is provided on both sides of the bottom of the load-bearing plate 13, and the load-bearing plate 13 is supported by the rubber pad 14. In this embodiment, by providing the rubber pad 14, when the transport vehicle goes uphill or downhill, the rubber pad 14 provides a certain supporting force, thereby reducing the pressure on the strap 41 caused by gravity, thereby increasing the service life of the strap 41.

[0026] In this embodiment, please refer to Figure 1 The interior of the cargo hold 1 includes at least three binding mechanisms, and all of them are controlled by independent driving devices to bind the cargo, and the binding straps are made of high-strength wear-resistant materials. In this embodiment, the binding mechanisms are used to fix the cargo through different driving structures. When the upper and lower parts of the cargo are of different shapes, they can be independently bound according to the shapes and sizes of the cargo. At the same time, when one of the binding mechanisms is damaged, the cargo can still be fixed to avoid damage. By using binding straps made of nylon and polyester fibers, it is ensured that the binding straps maintain a stable binding force during long-term and high-load transportation to avoid breaking of the binding straps.

[0027] Working principle of the present invention: Step 1: Place the goods in the inner cavity of the cargo hold 1, and use the driving motor 431 to give power to control the winding roller 43 to rotate, and use the winding roller 43 to wind up the end b of the strap 41. Since the end a of the strap 41 is fixed inside the fixed warehouse 42, when the winding roller 43 winds up the end of the strap 41, the inner diameter of the strap 41 gradually decreases, and the torsion spring 423 is deformed. When the inner diameter of the strap 41 gradually decreases, when the goods are placed in the inner cavity of the cargo hold 1, the strap 41 is used to deform the outer side of the goods. Binding, since the inner cavity of the cargo hold 1 is provided with a plurality of binding mechanisms, and they are respectively arranged at different heights in the inner cavity of the cargo hold 1, by controlling the inner diameter of the binding strap to gradually shrink, and by providing a self-locking device 46, the inner diameter of the binding strap is locked after being squeezed, and the driving motor 431 is stopped at the same time. This setting allows the binding strap to be bound according to the outer perimeter of the cargo. When the cargo presents an irregular shape with unequal widths from top to bottom, the binding straps arranged at different heights are respectively used to bind different positions of the cargo, and the cargo is fixed in the inner cavity of the cargo hold 1; Step 2, when the transport vehicle travels to the ramp, going uphill or downhill, the cargo will tilt under the influence of gravity and the center of gravity will shift. Since a load-bearing plate 13 is provided at the bottom of the inner cavity of the cargo hold 1, when the center of gravity of the cargo shifts, the load-bearing plate 13 will tilt under the pressure of the change in the center of gravity of the cargo. Since an inclination sensor 15 is provided inside the load-bearing plate 13, after monitoring the inclination of the load-bearing plate 13, it is judged that the center of gravity of the cargo has changed, and according to the inclination direction of the load-bearing plate 13, it is judged that the transport vehicle is in an uphill or downhill section at this time, and the information is sent to the control system. The control system issues a command, and the servo motor 44 gives power to control the gear 45 to rotate. Since the outer edge of the gear 45 is meshed with the outer edge of the rack 47 , the gear 45 is controlled to rotate and drive the rack 47 to move, and the moving direction of the rack 47 is controlled according to the rotation direction of the gear 45, and the rack 47 is controlled to move according to the direction of the center of gravity of the cargo. The rack 47 drives the strap 41 to move. Since the strap 41 is tied tightly to the top outside of the strap 41 at this time, the strap 41 is moved in the opposite direction of the center of gravity of the cargo. For example, when the transport vehicle is going uphill, the top of the cargo is moved forward by moving the strap 41, and when the transport vehicle is going downhill, the top of the cargo is moved backward by moving the strap 41 to correct the center of gravity of the cargo. When the center of gravity of the cargo is corrected successfully, the inclination sensor 15 monitors that the load-bearing plate 13 is no longer tilted, and the strap 41 can be fixed at this position to ensure smooth transportation of the cargo. Step 3: When the winding roller 43 is winding, the end a of the strap 41 continuously moves through the movable channel 421. As the inner diameter of the strap 41 is continuously reduced, until the pressing block 461 touches and squeezes the goods, the pressing block 461 moves backward, and the expansion plate 462 is pushed backward by the pressing block 461, and the linkage plate 464 is pushed backward by the push rod 463. When the linkage plate 464 moves backward, one side of the locking block 465 touches the strap 41. A locking groove 411 is provided at the a end of the belt 41. When the locking block 465 contacts the locking groove 411, the locking block 465 blocks the locking groove 411, thereby preventing the strap 41 from continuing to move. At this time, the driving motor 431 is stopped to drive the winding roller 43. Due to the mutual blocking of the locking groove 411 and the locking block 465, the goods vibrate due to bumps during transportation, so that the inner diameter of the strap 41 is fixed, further ensuring the stability of the goods during transportation.

[0028] The above shows and describes the basic principles, main features and advantages of the present invention. The present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
