Description

Technical Field

[0001] This utility model relates to the field of rail transit technology, and in particular to a stacked transport vehicle for rail transit. Background Technology

[0002] The stacked transport vehicle for rail transit is an intelligent logistics handling equipment specifically designed for rail transit (such as subways, light rail, high-speed rail, etc.). It is mainly used for the efficient and precise transport of rail vehicle components, maintenance equipment, or materials.

[0003] However, the loading compartments of most stacked pallet trucks cannot be easily disassembled. After long-term use, the garbage and dust accumulated inside the pallet truck are difficult to clean efficiently due to the obstruction of the transport compartment, which reduces the maintenance efficiency of the pallet truck. In addition, it is difficult to flexibly add additional transport compartments to the single-layer transport compartment of the stacked pallet truck to increase the carrying capacity, which affects the carrying efficiency of the pallet truck and thus reduces the practicality of the equipment.

[0004] Therefore, those skilled in the art have provided a stacking transport vehicle for rail transportation to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies and provide a stacked transport vehicle for rail transportation. The device completes basic installation and positioning by sliding the first transport compartment into the transport bracket. Then, it pushes the sliding rods at the four corners of the transport bracket so that the hooks at one end vertically pass through the middle of the mounting plate on the first transport compartment. The hooks are then twisted 90 degrees and pulled down, causing them to engage with the slots on the mounting plate. Finally, the fixing bolts on the rotating frame are twisted so that one end passes through the middle of one side of the fixing part and engages with the middle of the outer wall of the sliding rod. This makes the assembly and disassembly of the first transport compartment more flexible, and allows for efficient cleaning of debris on the transport bracket surface without obstruction from the first transport compartment, thus improving the practicality of the device.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A stacked transport vehicle for rail transportation includes a transport bracket, a pusher, a first transport compartment and a second transport compartment. Both ends of the two sides of the transport bracket and the first transport compartment are fixedly connected to a convenient maintenance mechanism, and one end of the upper surface of the transport bracket is fixedly connected to a quick disassembly mechanism.

[0008] The convenient maintenance mechanism includes multiple fixing parts. A rotating frame is fixedly connected to both ends of one side end face of the fixing part. A fixing bolt is threadedly connected to the middle of one side end face of the rotating frame. A slot is opened on both sides of one side end face of the fixing part. A sliding rod is slidably connected to the middle of one side end face of the fixing part. A hook rod is rotatably connected to one end of the sliding rod. Mounting plates are fixedly connected to both ends of both sides of the first transport compartment. A slot is opened on both sides of one side end face of the mounting plate.

[0009] Through the above technical solution, the device completes basic installation and positioning by sliding the first transport compartment into the transport bracket. Then, it pushes the sliding rods at the four corners of the transport bracket so that the hook rod at one end passes vertically through the middle of the mounting plate on the first transport compartment. Then, it twists the hook rod ninety degrees and pulls it down so that the hook rod engages with the slot on the mounting plate. Finally, it twists the fixing bolt on the rotating frame so that one end passes through the middle of one side of the fixed part and engages with the middle of one side of the outer wall of the sliding rod. The first transport compartment is more flexible to assemble and disassemble, and the debris on the surface of the transport bracket can be cleaned efficiently without the obstruction of the first transport compartment, thus improving the practicality of the device.

[0010] Furthermore, the quick assembly / disassembly mechanism includes a support plate, with connecting parts fixedly connected to both ends of the upper surface of the support plate. A knob is rotatably connected to the middle of one side end face of the connecting part. A connecting block is fixedly connected to one end of the outer wall of the knob. A retaining ring is fixedly connected to one end of the connecting block. A sliding groove is provided in the middle of one side end face of the connecting part. One end of a spring is fixedly connected to one end of the outer wall of the sliding groove. A retaining block is fixedly connected to the other end of the spring. An insertion groove is provided in one side end face of the connecting part. Pins are fixedly connected to both sides of the middle of one side end face of the second transport compartment.

[0011] Through the above technical solution, the device completes the initial installation and positioning by sliding the second transport compartment into the upper end of the first transport compartment until the pin at one end of the second transport compartment passes through one side of the support plate and enters the insertion groove on the connecting part. Then, the knob is turned to make the retaining ring rotate until one end of it passes through the insertion groove and engages with the end of the slid-in pin. At the same time, the retaining block is no longer blocked by the retaining ring and uses the spring elasticity to pop out from the slide groove and press against the connecting block to prevent the retaining ring from rebounding. This realizes the flexible addition of the second transport compartment to the upper end of the first transport compartment, improves the carrying capacity, and thus improves the practicality of the device.

[0012] Furthermore, a pusher is fixedly connected to one end of the transport bracket;

[0013] The above technical solution facilitates manual operation by track workers in non-automatic transport situations.

[0014] Furthermore, a first transport compartment is slidably connected to the upper end face of the transport bracket, and a second transport compartment is slidably connected to the upper end face of the first transport compartment;

[0015] Through the above technical solution, the first transport compartment serves as the basic loading tool for the handling vehicle and undertakes the main transportation task, while the second transport compartment is an additional transport unit used to increase the single transport capacity.

[0016] Furthermore, one end of the fixing bolt passes through the middle of one side end face of the fixing part and forms a locking connection with the middle of one side of the outer wall of the slide rod, and one end of the hook rod forms a locking connection with the bayonet.

[0017] With the above technical solution, the fixing bolts use the fixing part as the fixing fulcrum so that the slide rod can be fixed in the designated position. When the hook rod is engaged with the bayonet, the slide rod will not protrude from the upper end face of the fixing part, thus not hindering the installation of the first transport compartment.

[0018] Furthermore, the lower end of one side face of the first transport compartment is engaged with both ends of one side face of the transport bracket;

[0019] The above technical solution makes the installation and positioning of the first transport compartment more accurate and less prone to shaking or displacement during transportation after it is fixed.

[0020] Furthermore, the locking block forms a sliding connection with one side of the outer wall of the slide groove, and one end of the retaining ring passes through one end of the insertion groove and forms a locking connection with the pin;

[0021] With the above technical solution, the locking block is no longer blocked after the locking ring moves, and the spring elasticity allows it to pop out of the slide groove and press against the connecting block to prevent the locking ring from rebounding.

[0022] This utility model has the following beneficial effects:

[0023] 1. This utility model proposes a stacked transport vehicle for rail transportation. The device completes the basic installation and positioning by sliding the first transport compartment into the transport bracket. Then, it pushes the sliding rods at the four corners of the transport bracket so that the hook rod at one end passes vertically through the middle of the mounting plate on the first transport compartment. Then, it twists the hook rod ninety degrees and pulls it down so that the hook rod forms a locking connection with the slot on the mounting plate. Finally, it twists the fixing bolt on the rotating frame so that one end passes through the middle of one side of the fixing part and forms a locking connection with the middle of one side of the outer wall of the sliding rod. The first transport compartment is more flexible to disassemble and assemble, and the debris on the surface of the transport bracket can be cleaned efficiently without the obstruction of the first transport compartment, thus improving the practicality of the device.

[0024] 2. The present invention proposes a stacked transport vehicle for rail transportation. The device completes the initial installation and positioning by sliding the second transport compartment into the upper end of the first transport compartment until the pin at one end of the second transport compartment passes through one side of the support plate and enters the insertion groove on the connecting part. Then, the knob is turned to make the retaining ring rotate until one end of it passes through the insertion groove and engages with the end of the slid-in pin. At the same time, the retaining block is no longer blocked by the retaining ring and uses the elasticity of the spring to pop out from the slide groove and abut against the connecting block to prevent the retaining ring from rebounding. This realizes the flexible addition of the second transport compartment to the upper end of the first transport compartment, improves the carrying capacity, and thus improves the practicality of the device.

Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Reference Figure 1-3 This utility model provides a specific implementation method:

[0036] A stacked transport vehicle for rail transportation includes a transport bracket 1, a pusher 2, a first transport compartment 3, and a second transport compartment 5. Both ends of the transport bracket 1 and the first transport compartment 3 are fixedly connected to convenient maintenance mechanisms 4. One end of the upper surface of the transport bracket 1 is fixedly connected to a quick-release mechanism 6. The convenient maintenance mechanism 4 includes multiple fixing parts 41. A rotating frame 42 is fixedly connected to both ends of one side of the fixing part 41. A fixing bolt 43 is threadedly connected to the middle of one side of the rotating frame 42. A latch 44 is provided on both sides of one side of the fixing part 41. A sliding rod 45 is slidably connected to the middle of one side of the fixing part 41. A hook rod 46 is rotatably connected to one end of the sliding rod 45. Mounting plates 47 are fixedly connected to both ends of both sides of the first transport compartment 3. The mounting plate 47 has slots 48 on both sides of one end face. The device completes the basic installation and positioning by sliding the first transport chamber 3 into the transport bracket 1. Then, push the sliding rods 45 at the four corners of the transport bracket 1 so that the hook rods 46 at one end pass vertically through the middle of the mounting plate 47 on the first transport chamber 3. Then twist the hook rods 46 ninety degrees and pull them down so that the hook rods 46 and the slots 48 on the mounting plate 47 form a locking connection. Finally, twist the fixing bolts 43 on the rotating frame 42 so that one end passes through the middle of one end face of the fixing part 41 and forms a locking connection with the middle of one side of the outer wall of the sliding rod 45. The first transport chamber 3 is more flexible to disassemble and assemble. The debris on the surface of the transport bracket 1 can be cleaned efficiently without the obstruction of the first transport chamber 3, which improves the practicality of the device.

[0037] Reference Figure 3-7The quick-assembly / disassembly mechanism 6 includes a support plate 61. Connecting parts 62 are fixedly connected to both ends of the upper surface of the support plate 61. A knob 63 is rotatably connected to the middle of one side of the connecting part 62. A connecting block 64 is fixedly connected to one end of the outer wall of the knob 63. A retaining ring 65 is fixedly connected to one end of the connecting block 64. A sliding groove 66 is formed in the middle of one side of the connecting part 62. One end of a spring 67 is fixedly connected to one end of the outer wall of the sliding groove 66. A retaining block 68 is fixedly connected to the other end of the spring 67. A insertion groove 69 is formed in one side of the connecting part 62. Pins 610 are fixedly connected to both sides of the middle of one side of the second transport compartment 5. By sliding the second transport compartment 5 into the upper part of the first transport compartment 3 until the pin 610 at one end of the second transport compartment 5 passes through one side of the support plate 61 and enters the insertion groove 69 on the connecting part 62, the initial installation and positioning are completed. Then, the knob 63 is turned to make the retaining ring 65 rotate until one end of it passes through the insertion groove 69 and engages with one end of the slid-in pin 610. At the same time, the retaining block 68 is no longer blocked by the retaining ring 65. It uses the spring 67 to elastically pop out from the slide groove 66 and abut against the connecting block 64 to prevent the retaining ring 65 from rebounding. This realizes the flexible installation of the second transport compartment 5 on the upper part of the first transport compartment 3, improves the carrying capacity, and thus improves the practicality of the device.

[0038] One end of the transport bracket 1 is fixedly connected to a pusher 2, which facilitates manual operation by track workers in non-automatic transport situations.

[0039] The upper end face of the transport bracket 1 is slidably connected to the first transport compartment 3, and the upper end face of the first transport compartment 3 is slidably connected to the second transport compartment 5. The first transport compartment 3 serves as the basic loading tool of the transport vehicle and undertakes the main transport task. The second transport compartment 5 is an additional transport unit to increase the single transport capacity.

[0040] One end of the fixing bolt 43 passes through the middle of one side end face of the fixing part 41 and forms a locking connection with the middle of one side of the outer wall of the slide rod 45. One end of the hook rod 46 forms a locking connection with the bayonet 44. The fixing bolt 43 uses the fixing part 41 as a fixing fulcrum so that the slide rod 45 can be fixed in the designated position. When the hook rod 46 is locked with the bayonet 44, the slide rod 45 will not protrude from the upper end face of the fixing part 41, so as not to hinder the installation of the first transport compartment 3.

[0041] The lower end of one side face of the first transport compartment 3 is engaged with both ends of one side face of the transport bracket 1, making the installation and positioning of the first transport compartment 3 more accurate and less prone to shaking or displacement during transportation after it is fixed.

[0042] The locking block 68 is slidably connected to one side of the outer wall of the slide groove 66. One end of the retaining ring 65 passes through one end of the insertion groove 69 and is engaged with the pin 610. After the retaining ring 65 moves, the locking block 68 is no longer blocked. The spring 67 elastically pops out of the slide groove 66 and abuts against the connecting block 64 to prevent the retaining ring 65 from rebounding.

[0043] Working principle: The device completes basic installation and positioning by sliding the first transport compartment 3 into the transport bracket 1. Then, it pushes the sliding rods 45 at the four corners of the transport bracket 1 so that the hook rods 46 at one end pass vertically through the middle of the mounting plate 47 on the first transport compartment 3. Then, it twists the hook rods 46 ninety degrees and pulls them down so that the hook rods 46 and the slots 48 on the mounting plate 47 form a locking connection. Finally, it twists the fixing bolts 43 on the rotating frame 42 so that one end passes through the middle of one side of the fixing part 41 and forms a connection with the middle of one side of the outer wall of the sliding rod 45. The device completes the initial installation and positioning by sliding the second transport compartment 5 into the upper end of the first transport compartment 3 until the pin 610 at one end of the second transport compartment 5 passes through one side end face of the support plate 61 and enters the insertion groove 69 on the connecting part 52. Then, the knob 63 is turned to make the retaining ring 65 rotate until one end of it passes through the insertion groove 69 and engages with one end of the slid-in pin 610. At the same time, the retaining block 68 is no longer blocked by the retaining ring 65 and uses the spring 67 to elastically pop out from the slide groove 66 and abut against the connecting block 64 to prevent the retaining ring 65 from rebounding.
