Description
Technical Field
[0001] This utility model relates to the field of transportation engineering technology, specifically to a track structure for a self-propelled, integrated, double-rail transport machine. Background Technology
[0002] In mountainous and hilly areas, traditional transportation methods are limited by terrain, resulting in problems such as low transportation efficiency and high costs. Among existing technologies, there are self-propelled integrated double-rail transport machine track structures specifically designed for mountainous and hilly terrain. These track structures are usually made in one piece, giving the double rails good integrity and stability. They can adapt to the complex terrain conditions of mountainous and hilly areas, providing a stable operating foundation for self-propelled transport machines. This helps to achieve more efficient and convenient transportation of materials or personnel in mountainous and hilly areas, and to a certain extent improves the constraints of mountainous and hilly terrain on transportation.
[0003] In the existing technology for special tracks in mountainous and hilly terrain, the use of welding for the support rods connecting the tracks has obvious drawbacks. Welding operations not only require specialized welding equipment and personnel, but also complex on-site operations, which makes the track installation process time-consuming and greatly reduces construction efficiency. Moreover, the welded support rods are fixedly connected to the track and cannot be disassembled. When the track is partially damaged and needs repair or replacement, or when the track needs to be adjusted due to changes in terrain utilization requirements, the welded parts must be destructively removed. This not only wastes materials, but also further increases the cost and difficulty of subsequent maintenance and modification, seriously affecting the flexible application and long-term operation and maintenance of the tracks in complex mountainous and hilly environments.

[0008] Preferably, the auxiliary support assembly includes a threaded support sleeve and a threaded disassembly cap inside. The threaded support sleeve is fixedly installed on the outer wall of the end of the pneumatic transmission pipe away from the bottom of the sealed assembly cavity, and the threaded disassembly cap is threadedly installed on the outer wall of the threaded support sleeve.
[0009] Preferably, the threaded disassembly cover has a cover compression cavity inside, and the top circumference of the threaded support sleeve has an external thread. The external thread of the sleeve and the cover compression cavity are adapted to each other. A cavity linkage piston is movably sleeved inside the threaded support sleeve. A gas flow port is opened inside one side of the cavity linkage piston. A piston guide rod is fixedly installed on the top of the gas flow port. A gravity push rod is movably sleeved inside the piston guide rod, and a connecting rod is fixedly installed on the top of the gravity push rod. The bottom of the connecting rod and the top of the gas flow port fit together. A rod limiting block is fixedly connected to the end of the gravity push rod away from the connecting rod.
[0010] Preferably, a piston linkage transmission rod is fixedly installed on the top of the cavity linkage piston, the top of the piston linkage transmission rod passes through the top of the threaded support sleeve and a compression spring is movably sleeved on the outer wall, and a transmission rod compression head is fixedly installed on the end of the piston linkage transmission rod away from the cavity linkage piston.
[0011] Preferably, a gas anti-backflow seat is fixedly installed inside the threaded support sleeve on the side near the cavity linkage piston. A connecting plate is fixedly installed inside the gas anti-backflow seat. An anti-backflow linkage rod is opened inside the connecting plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This type of self-propelled, integrated, double-rail transporter track structure uses a track connecting rod as a connecting support between the connecting rod and the track connecting block. It can directly fit into the sealed assembly cavity inside the track connecting block. The sealed assembly cavity and the pneumatic push cavity form a pneumatic transmission structure. After the gas enters the pneumatic push cavity, it pushes the limit block to extend and fit into the slot at the bottom of the track connecting rod. The entire process does not require welding. Through the synergistic effect of the track connecting block, track connecting rod, sealed assembly cavity, pneumatic push cavity, and limit block, it replaces traditional welding operations, avoids dependence on professional welding resources, simplifies the assembly process, and quickly completes the fixation of the track and the base, solving the problems of low installation efficiency and high technical threshold.
[0014] 2. This self-propelled, integrated, double-rail transporter track structure uses a threaded disassembly cover and a threaded support sleeve connected by threads. Disassembly and assembly can be achieved by rotating the threaded disassembly cover. During disassembly, after the threaded disassembly cover is removed, the compression spring rebounds and pushes the piston linkage transmission rod, causing the cavity linkage piston to move upward. This, in turn, causes the limit block to retract and release the limit on the track connecting rod, achieving non-destructive separation of the connecting rod from the track base. During subsequent resetting, the threaded engagement between the threaded disassembly cover and the threaded support sleeve drives the cavity linkage piston, piston linkage transmission rod, and compression spring to work together to restore the seal. The detachable nature of the threaded support sleeve, threaded disassembly cover, cavity linkage piston, piston linkage transmission rod, and compression spring replaces the traditional welded fixed connection, allowing for maintenance and adjustment without destructive disassembly. This solves the problems of difficult operation and maintenance, material waste, and high costs. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-4 This utility model provides a technical solution for a self-propelled, one-piece molded dual-rail transport track structure: A self-propelled, one-piece molded dual-rail transport track structure includes a track base 1, a track connecting block 2 fixedly installed on the top of the track base 1, an auxiliary support component 3 embedded inside the track connecting block 2, a track connecting rod 4 embedded in the middle inner cavity of the track connecting block 2, a connecting rod 6 fixedly installed on the top of the track connecting rod 4, support rods 8 fixedly connected to both sides of the connecting rod 6, and a pneumatic conveying component 5 fixedly installed on the side of the track connecting block 2, with the top of the pneumatic conveying component 5 and one side of the track connecting block 2 internally fixedly connected.
[0022] During the operation, when the connecting rod 6 and the support rod 8 need to be installed on the top of the track base 1, the track connecting rod 4, which has been fixedly installed at the bottom of the connecting rod 6, can be internally embedded and assembled with the track connecting block 2. During the assembly process, gas will be delivered to the inside of the track base 1 through the air pressure conveying component 5. With the help of the generated air pressure, the bottom of the track connecting rod 4 can be tightly limited inside the track connecting block 2, thereby achieving rapid fixation and improving installation efficiency.
[0023] Example 2:
[0024] Two symmetrical slots 41 are opened on both sides of the bottom of the track connecting rod 4. The interior of the track connecting block 2 includes a sealed assembly cavity 21. The sealed assembly cavity 21 is located inside the track connecting block 2. The side of the sealed assembly cavity 21 is connected to the air pressure pushing cavity 22. The air pressure pushing cavity 22 is movably sleeved with the internal piston 23. The outer wall of the internal piston 23 is fixedly installed with a limit block 24.
[0025] The pneumatic conveying assembly 5 includes a pneumatic transmission pipe 51. The pneumatic transmission pipe 51 is fixedly installed at the bottom of the sealed assembly cavity 21. A pipe sealing seat 52 is fixedly installed inside the pneumatic transmission pipe 51. A connection port is provided inside the pipe sealing seat 52. A sealing plug mounting plate 53 is fixedly installed inside the connection port. A sealing plug connecting rod 54 is movably sleeved inside the sealing plug mounting plate 53. A pipe sealing plug 55 is fixedly installed on one side of the sealing plug connecting rod 54. A spring compression block 57 is fixedly installed on the outer wall of the end of the sealing plug connecting rod 54 away from the pipe sealing plug 55. A sealing plug return spring 56 is movably sleeved on the outer circumference of the end of the sealing plug connecting rod 54 near the spring compression block 57.
[0026] During installation, the track connecting rod 4 at the bottom of the connecting rod 6, which is used for fixed installation, can be internally embedded and assembled with the track connecting block 2. During installation, the track connecting rod 4 can extend into the interior of the sealing assembly cavity 21. As it extends into the interior, the bottom of the track connecting rod 4 can be inserted and engaged with the top of the sealing assembly cavity 21, thereby forming a sealed state inside the sealing assembly cavity 21.
[0027] After sealing is completed, the track connecting rod 4 continues to move downwards along the interior of the sealing assembly cavity 21. During this movement, the track connecting rod 4 will compress the gas stored inside the sealing assembly cavity 21. The compressed gas will enter the interior of the pressure transmission pipe 51. As the track connecting rod 4 continues to penetrate deeper into the sealing assembly cavity 21, the compressive force on the gas continues to increase, causing the gas pressure to gradually rise. When the high-pressure gas passes through the connection port, it will tightly adhere to the outer wall of the pipe sealing plug 55. During the contact process, the gas will exert a thrust on the pipe sealing plug 55. When the thrust reaches a certain level, the pipe sealing plug 55 will detach from the contact state with the connection port.
[0028] As the pipe sealing plug 55 moves forward, the sealing plug connecting rod 54, which is fixedly connected to its outer wall, moves forward synchronously with the pipe sealing plug 55. Meanwhile, the spring compression block 57, which is fixedly connected to the outer wall of the sealing plug connecting rod 54, moves towards the sealing plug mounting plate 53. During the movement, the spring compression block 57 compresses the sealing plug return spring 56, which is movably sleeved on the outer wall of the sealing plug connecting rod 54, causing the sealing plug return spring 56 to initially complete its power storage. When the pipe sealing plug 55 is completely disengaged from the connection port, the compressed high-pressure gas can be transported through the connection port to the interior of the pneumatic pushing chamber 22. As the gas accumulates in the pneumatic pushing chamber 22, the gas density gradually increases, and the resulting pressure pushes the limiting block 24 out of the pneumatic pushing chamber 22. Finally, the limiting block 24 and the slot 41 are internally embedded and installed, forming a stable and fixed structure. At this time, the connecting rod 6 can be securely installed on the top of the track base 1.
[0029] When the gas inside the sealing assembly cavity 21 is completely squeezed into the gas pressure transmission tube 51, the squeezing force on the sealing plug return spring 56 disappears, and then the reset begins. During the reset process, the sealing plug return spring 56 will push the spring squeezing block 57 to one side. Through the connection between the spring squeezing block 57 and the sealing plug connecting rod 54, the pipe sealing plug 55 can be pulled back to the side of the pipe sealing seat 52, so that the pipe sealing plug 55 re-fits the connection port, thereby effectively preventing the gas that has been delivered to the sealing assembly cavity 21 from flowing back.
[0030] Example 3:
[0031] The auxiliary support assembly 3 includes a threaded support sleeve 31 and a threaded disassembly cover 32. The outer wall of the pneumatic transmission pipe 51 away from the bottom of the sealed assembly cavity 21 is fixedly installed with the threaded support sleeve 31, and the threaded disassembly cover 32 is threadedly installed on the outer wall of the threaded support sleeve 31.
[0032] The threaded disassembly cover 32 has a cover extrusion cavity 33 inside. The top circumference of the threaded support sleeve 31 has an external thread 34. The external thread 34 and the cover extrusion cavity 33 are compatible with each other. The threaded support sleeve 31 is movably sleeved with a cavity linkage piston 35. A gas flow port 37 is opened inside one side of the cavity linkage piston 35. A piston guide rod 38 is fixedly installed on the top of the gas flow port 37. A gravity push rod 39 is movably sleeved inside the piston guide rod 38. A connecting rod 6 is fixedly installed on the top of the gravity push rod 39. The bottom of the connecting rod 6 and the top of the gas flow port 37 are in contact with each other. A rod limiting block 61 is fixedly connected to the end of the gravity push rod 39 away from the connecting rod 6.
[0033] A piston linkage transmission rod 69 is fixedly installed on the top of the cavity linkage piston 35. The top of the piston linkage transmission rod 69 passes through the top of the threaded support sleeve 31 and a compression spring 7 is movably sleeved on the outer wall. A transmission rod compression head 71 is fixedly installed on the end of the piston linkage transmission rod 69 away from the cavity linkage piston 35.
[0034] A gas anti-backflow seat 62 is fixedly installed inside the threaded support sleeve 31 on the side near the cavity linkage piston 35. A connecting plate 63 is fixedly installed inside the gas anti-backflow seat 62. An anti-backflow linkage rod 64 is opened inside the connecting plate 63. A spring compression piece 65 is fixedly installed at the bottom of the anti-backflow linkage rod 64. A channel sealing block 68 is fixedly installed on the outer wall of the end of the anti-backflow linkage rod 64 away from the spring compression piece 65. A gas flow channel 67 is opened inside the gas anti-backflow seat 62. The interior of the gas flow channel 67 is fixedly connected to the two transverse ends of the connecting plate 63. An anti-backflow reset spring 66 is movably sleeved on the outer wall of the end of the anti-backflow linkage rod 64 near the spring compression piece 65.
[0035] If it is necessary to disconnect and disassemble the connection between the connecting rod 6 and the track base 1 during operation, the following steps can be taken:
[0036] First, the threaded removal cover 32 is rotated. During rotation, the threaded removal cover 32 is completely removed from the top of the threaded support sleeve 31. After the threaded removal cover 32 is removed, the compressive force applied by the compression spring 7, which was originally movably sleeved on the outer wall of the piston linkage transmission rod 69, will disappear. After the compressive force of the compression spring 7 disappears, it will generate a rebound force, which will push the transmission rod compression head 71 upward. As the transmission rod compression head 71 is pushed up, it will move upward. When the piston linkage transmission rod 69 and the transmission rod compression head 71 move upward together, the cavity linkage piston 35, which is fixedly connected to the bottom of the two, will move upward synchronously along the inside of the threaded support sleeve 31.
[0037] As the piston 35 moves upward, a suction force is generated at its bottom. This suction force also generates a suction force at the top of the piston guide rod 38, which pulls the channel sealing block 68 upward. During this pulling process, the anti-backflow linkage rod 64, which is fixedly connected to its bottom, can move upward along the inside of the connecting plate 63. Simultaneously, as the anti-backflow linkage rod 64 moves upward, it drives the spring compression plate 65 to move upward as well. The movement of the spring compression plate 65 then compresses the anti-backflow reset spring 66, which is movably sleeved on the outer wall of the anti-backflow linkage rod 64, causing the anti-backflow reset spring 66 to generate a rebound force.
[0038] When the channel sealing block 68 moves away from the end of the gas flow channel 67, the interior of the gas flow channel 67 opens, thereby connecting the threaded support sleeve 31 and the pneumatic transmission pipe 51. At this time, the gas stored in the pneumatic push chamber 22 is drawn into the bottom of the chamber linkage piston 35. During the process of gas being drawn in, a suction force is generated inside the pneumatic push chamber 22. This suction force drives the piston 23 inside the chamber to move towards one end of the pneumatic transmission pipe 51. The movement of the piston 23 inside the chamber causes the limiting block 24 fixedly connected to its outer wall to retract into the pneumatic push chamber 22. As the limiting block 24 retracts, the original limiting force on the connecting rod 6 is canceled. At this point, the connecting rod 6 can be removed from the top of the track base 1 for subsequent replacement.
[0039] When the cavity linkage piston 35 moves to the appropriate position, the suction force generated at its bottom will disappear. At this time, the compressive force on the anti-backflow return spring 66 will also be released, and the anti-backflow return spring 66 will automatically reset. During the reset process of the anti-backflow return spring 66, it will push the spring compression plate 65 downward, thereby causing the outer wall of the channel sealing block 68 to tightly adhere to the top of the gas anti-backflow seat 62, effectively preventing the gas stored at the bottom of the cavity linkage piston 35 from flowing back.
[0040] After disassembly, the cover compression chamber 33 inside the threaded disassembly cover 32 can be connected to the external thread 34 on the outer wall of the threaded support sleeve 31 via threads. During the connection process, the top of the transmission rod compression head 71 will compress against the bottom of the cover compression chamber 33, causing the transmission rod compression head 71 to push the piston linkage transmission rod 69 to retract into the threaded support sleeve 31. When the piston linkage transmission rod 69 retracts, the cavity linkage piston 35 fixedly installed at the bottom of the transmission rod compression head 71 will move downward along the inside of the threaded support sleeve 31. During the downward movement of the cavity linkage piston 35, it will compress the gas at its bottom, and the pressure of the compressed gas will increase accordingly.
[0041] At this time, the gas with increased pressure will come into contact with the bottom of the connecting rod 6 through the gas flow port 37. During the contact process, an upward thrust will be generated, which will push open the top of the gas flow port 37, so that the gas stored at the bottom of the cavity linkage piston 35 can be delivered to the top of the cavity linkage piston 35. In addition, during the downward movement of the transmission rod extrusion head 71, it will compress the compression spring 7 that is movably sleeved on the outer wall of the piston linkage transmission rod 69. At the same time, when the cavity linkage piston 35 moves upward, the connecting rod 6 will push the gravity push rod 39 downward along the inside of the piston guide rod 38 due to its own gravity, and finally come into contact with the top of the gas flow port 37. When the compression spring 7 returns to its original position, the gas stored inside the threaded support sleeve 31 can be discharged through the cavity linkage piston 35, preventing the gas from flowing back through the gas flow port 37 and ensuring the sealing and stability of the entire operation process.
[0042] Working principle:
[0043] Step 1: Install the fixed pneumatically driven quick-release assembly
[0044] When installing the connecting rod 6 and the compression spring 7 onto the top of the track base 1, first, the track connecting rod 4, which is fixed at the bottom of the connecting rod 6, is embedded and assembled inside the track connecting block 2, so that the track connecting rod 4 extends into the sealed assembly cavity 21 inside the track connecting block 2. As the track connecting rod 4 continues to extend downward, it will form a sealing fit with the top of the sealed assembly cavity 21 and compress the gas stored inside the sealed assembly cavity 21. After the compressed gas enters the gas pressure conduction pipe 51, the pressure gradually increases. The high-pressure gas pushes the pipe sealing plug 55 away from the connection port of the pipe sealing seat 52, and then through the connection... The gas is delivered to the pneumatic push chamber 22. When the gas pressure in the pneumatic push chamber 22 reaches the threshold, it will push the limiting block 24 to extend out of the pneumatic push chamber 22 and finally complete the fitting with the slots 41 on both sides of the bottom of the track connecting rod 4. At the same time, the pneumatic assist delivered by the pneumatic delivery component 5 will tightly limit the bottom of the track connecting rod 4 inside the track connecting block 2, so as to realize the quick and stable installation of the connecting rod 6 and the track base 1. After the gas is completely delivered, the sealing plug return spring 56 will reset due to the disappearance of the squeezing force, pull the pipe sealing plug 55 to re-fit the connection port, prevent gas backflow, and maintain the fixed state.
[0045] Step 2: Disassemble and separate the suction drive limit release and components.
[0046] If it is necessary to disassemble the connection between the connecting rod 6 and the track base 1, first rotate the threaded disassembly cover 32 and remove it from the top of the threaded support sleeve 31. At this time, the compressive force of the compression spring 7 on the outer wall of the piston linkage transmission rod 69 disappears, and the compression spring 7 generates a rebound force to lift the transmission rod compression head 71, causing the piston linkage transmission rod 69 and the transmission rod compression head 71 to move upward synchronously. This, in turn, pulls the bottom-fixed cavity linkage piston 35 to move upward along the inside of the threaded support sleeve 31. During the upward movement of the cavity linkage piston 35, a suction force is formed at the bottom, which is transmitted to the channel sealing block 68 through the piston guide rod 38 and pulls it upward, causing the anti-backflow linkage rod 64 at the bottom of the channel sealing block 68 to move upward along the connecting plate 63. At the same time, the spring compression plate 65 compresses the anti-backflow reset spring 66 to store force. When the channel sealing block 68 moves away from the gas flow channel 67, the gas flow channel 67 opens, the threaded support sleeve 31 connects with the air pressure transmission pipe 51, and the gas in the air pressure pushing chamber 22 is drawn into the bottom of the cavity linkage piston 35. The suction force generated by the air pressure pushing chamber 22 pulls the piston 23 in the cavity towards the air pressure transmission pipe 51, causing the limiting block 24 to retract back into the air pressure pushing chamber 22. The original limiting force on the connecting rod 6 is released, and the connecting rod 6 can be disassembled from the top of the track base 1. After the cavity linkage piston 35 moves to the appropriate position, the suction force disappears, the anti-backflow reset spring 66 resets the pushing spring extrusion plate 65 and moves it down, so that the channel sealing block 68 fits against the top of the gas anti-backflow seat 62, preventing the gas from flowing back from the bottom of the cavity linkage piston 35.
[0047] Step 3: Reset the gas regulation and state restoration of the seal compression drive
[0048] After disassembly, the cover extrusion chamber 33 inside the threaded disassembly cover 32 is connected to the external thread 34 of the outer wall of the threaded support sleeve 31 via threads. During the connection process, the bottom of the cover extrusion chamber 33 extrudes the transmission rod extrusion head 71, causing the transmission rod extrusion head 71 to push the piston linkage transmission rod 69 to contract into the threaded support sleeve 31, thereby driving the cavity linkage piston 35 to move downward along the inside of the threaded support sleeve 31. When the cavity linkage piston 35 moves downward, it extrudes the gas at the bottom, increasing the gas pressure. The high-pressure gas passes through the gas flow port 37 and comes into contact with the bottom of the connecting rod 6, generating an upward thrust that pushes open the gas... At the top of the gas flow port 37, gas is delivered to the top of the cavity linkage piston 35. At the same time, the downward movement of the transmission rod compression head 71 will compress the compression spring 7 on the outer wall of the piston linkage transmission rod 69. During the upward movement of the cavity linkage piston 35, the connecting rod 6 pushes the gravity push rod 39 downward along the piston guide rod 38 due to gravity and fits against the top of the gas flow port 37. When the compression spring 7 returns to its original position, the gas stored inside the threaded support sleeve 31 can be discharged through the cavity linkage piston 35, preventing the gas from flowing back through the gas flow port 37 and ensuring that the entire track structure returns to a sealed state, preparing for the next installation or operation.
