Description

Technical Field

[0001] The present invention relates to the technical field of logistics and transportation, and in particular to a traction transport vehicle and a material transportation system. Background Art

[0002] Within a production industrial park, materials need to be transported between multiple production plants. For example, materials need to be transported from Building A to Building B for production, and then transported to Building C for storage. Conventional technology relies on forklifts and manual labor for long-distance, frequent transport operations.

[0003] However, the large distances between related production plants within the industrial park, and the inconsistent heights and types of docking platforms connecting to the production plants, resulted in low transportation efficiency, high labor intensity, and high production costs. Furthermore, the use of forklifts for long-distance transportation resulted in high operating and maintenance costs and energy consumption. The need for manual packaging to protect materials from rain, pests, and foreign objects during transportation further reduced transportation efficiency and increased production costs. Some lighter cargo could not be transported by forklifts and required manual use of hydraulic trucks, which was labor-intensive and inefficient.

[0004] In the prior art, ordinary transport vehicles are used for material transportation, and their carriages cannot be raised or lowered to adapt to docking platforms of different heights. Since the carriages are integrally connected to the vehicle body, the transport vehicles need to wait on the spot when loading and unloading materials, resulting in low transportation efficiency. Summary of the Invention

[0005] The present invention aims to solve at least one of the technical problems in the above-mentioned technologies to a certain extent. To this end, one object of the present invention is to provide a tractor transport vehicle that facilitates material loading, improves transportation efficiency, reduces material transportation costs, and provides effective and comprehensive safety protection during material transportation.

[0006] The second object of the present invention is to provide a material transportation system, including the above-mentioned tractor transport vehicle, so as to improve transportation efficiency and reduce material transportation costs.

[0007] To achieve the above objectives, a first embodiment of the present invention provides a tractor transport vehicle, comprising:

[0008] A traction unit, wherein the traction unit is provided with a first mounting seat and a second mounting seat which are arranged opposite to each other, and a first clearance space is formed between the first mounting seat and the second mounting seat;

[0009] a first lifting unit, the first lifting unit being mounted on the first mounting seat;

[0010] a second lifting unit, the second lifting unit being mounted on the second mounting base;

[0011] a first supporting plate, the first supporting plate being mounted on the first lifting unit;

[0012] The second supporting plate is installed on the second lifting unit. The second supporting plate is arranged opposite to the first supporting plate, and a second making way space is formed between the second supporting plate and the first supporting plate.

[0013] According to a traction transport vehicle of an embodiment of the present invention, when transporting a loaded carriage, the traction unit moves and drives the carriage to be placed in the first and second clearance spaces, and the first and second lifting units simultaneously drive the first and second pallets to rise and lift the carriage. The traction unit then moves the lifted carriage to the destination, and then the first and second lifting units simultaneously drive the first and second pallets to lower and unload the carriage. The traction unit then leaves and transports the next carriage, without the traction unit having to wait in place. Therefore, the carriage of the present invention is separable from the traction unit, making material loading convenient, improving transportation efficiency, and reducing material transportation costs.

[0014] In addition, the tractor transport vehicle according to the above embodiment of the present invention may also have the following additional technical features:

[0015] Furthermore, it also includes a carriage, which has a first hanger on one side for the first pallet to abut against, and a second hanger on the other side for the second pallet to abut against, and the width of the carriage matches the first and second clearance spaces so that the carriage can be placed in the first and second clearance spaces.

[0016] When transporting a loaded carriage, the traction unit moves to drive the carriage to the first and second clearance spaces, and the first and second lifting units simultaneously drive the first and second pallets to rise, respectively abutting against the first and second hanging parts of the carriage and lifting the carriage. The traction unit then moves the lifted carriage to the destination, and then the first and second lifting units simultaneously drive the first and second pallets to descend, unloading the carriage. The traction unit then leaves and transports the next carriage, without the traction unit having to wait in place. Therefore, the carriage of the present invention is separable from the traction unit, making material loading convenient, improving transportation efficiency, and reducing material transportation costs.

[0017] Furthermore, the first lifting unit and the second lifting unit are hydraulic scissor-type mechanisms, including a hydraulic cylinder and a scissor-type mechanism, and the hydraulic cylinder drives the scissor-type mechanism to rise and fall.

[0018] Furthermore, the inner ends of the first support plate and the second support plate are connected by a connecting plate, and the whole structure is a U-shaped structure with an outer side opening.

[0019] Furthermore, anti-fall-off blocks are respectively provided on the outer ends of the first support plate and the second support plate.

[0020] Furthermore, the traction unit is configured as a three-wheel structure, wherein the number of front wheels is one and the number of rear wheels is two.

[0021] Furthermore, anti-collision plates are provided on both side surfaces of the carriage in a vertical direction, and the anti-collision plates are located at the insertion end of the carriage into the first clearance space and the second clearance space.

[0022] To achieve the above-mentioned object, a second embodiment of the present invention provides a material transportation system, including a tractor transport vehicle, and further comprising:

[0023] connecting platform;

[0024] A support platform is provided with passages on both sides of the support platform, and the passages extend to the docking platform. The support platform can be placed in the first clearance space of the traction transport vehicle. The support platform and the docking platform cooperate to support the carriage that is unloaded by the simultaneous descent of the first lifting unit and the second lifting unit.

[0025] According to a material transportation system according to an embodiment of the present invention, when a traction unit transports a loaded carriage to a docking platform, the traction unit pulls the lifted carriage to the docking platform. At this time, the traction unit moves to the passageways on both sides of the support platform, and the support platform gives way to the first clearance space of the traction transport vehicle, so that the carriage reaches the docking platform and above the support platform. The first lifting unit and the second lifting unit simultaneously drive the first pallet and the second pallet to descend, placing the carriage on the docking platform and the support platform, unloading the carriage, and then the traction unit leaves to transport the next carriage, without the traction unit having to wait in place. Therefore, the carriage and the traction unit of the present invention are separable, making material loading convenient, improving transportation efficiency, and reducing material transportation costs.

[0026] In addition, the material transportation system proposed in the above embodiment of the present invention may also have the following additional technical features:

[0027] Furthermore, the height of the support platform is consistent with the height of the docking platform. BRIEF DESCRIPTION OF THE DRAWINGS

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0044] When transporting a loaded carriage, the present invention moves the traction unit to place the carriage in the first and second clearance spaces. The first and second lifting units simultaneously drive the first and second pallets to rise and lift the carriage. The traction unit then moves the lifted carriage to the destination. The first and second lifting units then simultaneously drive the first and second pallets to descend, unloading the carriage. The traction unit then leaves and transports the next carriage, eliminating the need for the traction unit to wait. Therefore, the carriage and traction unit of the present invention are separable, making material loading easier, improving transportation efficiency, and reducing material transportation costs.

[0045] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Instead, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0046] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0047] Example 1

[0048] like Figures 1 to 3 As shown, the present invention discloses a traction transport vehicle, including a traction unit 1, a first lifting unit 2, a second lifting unit 3, a first pallet 4 and a second pallet 5; the traction unit 1 is provided with a first mounting seat 11 and a second mounting seat 12 arranged opposite to each other, and a first makeshift space is formed between the first mounting seat 11 and the second mounting seat 12; the first lifting unit 2 is mounted on the first mounting seat 11, and the second lifting unit 3 is mounted on the second mounting seat 12; the first pallet 4 is mounted on the first lifting unit 2, and the second pallet 5 is mounted on the second lifting unit 3; the second pallet 5 and the first pallet 4 are arranged opposite to each other, and a second makeshift space is formed between the second pallet 5 and the first pallet 4.

[0049] When transporting a loaded carriage 6, the traction unit 1 moves and drives the carriage 6 to be placed in the first and second clearance spaces, and the first and second lifting units 2 and 3 simultaneously drive the first and second pallets 4 and 5 to rise and lift the carriage 6. The traction unit 1 then moves the lifted carriage 6 to the destination, and then the first and second lifting units 2 and 3 simultaneously drive the first and second pallets 4 and 5 to descend, unloading the carriage 6. The traction unit 1 then leaves and transports the next carriage 6, without the traction unit 1 having to wait in place. Therefore, the carriage 6 of the present invention can be separated from the traction unit 1, making material loading convenient, improving transportation efficiency, and reducing material transportation costs.

[0050] The traction transport vehicle also includes a carriage 6, one side of which is provided with a first hanger 61 for the first pallet 4 to abut against, and the other side of which is provided with a second hanger 62 for the second pallet 5 to abut against. The width of the carriage 6 matches the first and second clearance spaces so that the carriage 6 can be placed in the first and second clearance spaces.

[0051] When transporting a loaded carriage 6, the traction unit 1 moves and drives the carriage 6 to be placed in the first and second clearance spaces, and the first lifting unit 2 and the second lifting unit 3 simultaneously drive the first pallet 4 and the second pallet 5 to rise, respectively abutting against the first hanger 61 and the second hanger 62 of the carriage 6 and lifting the carriage 6. The traction unit 1 then moves the lifted carriage 6 to the destination, and then the first lifting unit 2 and the second lifting unit 3 simultaneously drive the first pallet 4 and the second pallet 5 to descend, unloading the carriage 6. The traction unit 1 then leaves and transports the next carriage 6, and the traction unit 1 does not need to wait in place. Therefore, the carriage 6 of the present invention can be separated from the traction unit 1, making material loading convenient, improving transportation efficiency, and reducing material transportation costs.

[0052] In some examples, the first and second lifting units 2 and 3 are hydraulic scissor mechanisms 7, including a hydraulic cylinder 71 and a scissor mechanism 72. The hydraulic cylinder 71 drives the scissor mechanism 72 up and down. The first and second lifting units 2 and 3 can raise or lower the carriage 6, thereby accommodating docking platforms of varying heights and configurations. The first and second lifting units 2 and 3 can also have other configurations. The first and second lifting units 2 and 3 can utilize batteries to provide lifting power.

[0053] In some examples, the inner ends of the first support plate 4 and the second support plate 5 are connected by a connecting plate 41 , and the overall structure is a U-shaped structure with an outer side opening, so that the first support plate 4 and the second support plate 5 have better stability and strength.

[0054] In some examples, anti-fall-off blocks 42 are respectively provided at the outer ends of the first pallet 4 and the second pallet 5 to prevent the carriage 6 from detaching from the first pallet 4 and the second pallet 5 due to the shaking of the traction unit 1 during transportation of materials, thereby improving the safety of materials during transportation.

[0055] In some examples, the tractor unit 1 is configured as a three-wheeled structure, with one front wheel and two rear wheels. This configuration allows the tractor transport vehicle to have a wider steering angle and adapt to complex cornering conditions. The tractor unit 1 can be powered by a battery. Safety obstacle sensors can be installed on the tractor unit 1 to ensure safe operation.

[0056] In some examples, anti-collision plates are provided on both side surfaces of the carriage 6 in the vertical direction. The anti-collision plates are located at the insertion ends of the carriage 6 where the first and second clearance spaces are inserted to prevent the carriage 6 from being damaged when inserted into the first and second clearance spaces.

[0057] Example 2

[0058] like Figures 4 and 5As shown, the present invention discloses a material transportation system, which includes a traction transport vehicle, a docking platform 8 and a support platform 9.

[0059] The traction transport vehicle includes a traction unit 1, a first lifting unit 2, a second lifting unit 3, a first pallet 4 and a second pallet 5; the traction unit 1 is provided with a first mounting seat 11 and a second mounting seat 12 arranged opposite to each other, and a first makeshift space is provided between the first mounting seat 11 and the second mounting seat 12. The first lifting unit 2 is mounted on the first mounting seat 11, and the second lifting unit 3 is mounted on the second mounting seat 12. The first pallet 4 is mounted on the first lifting unit 2, and the second pallet 5 is mounted on the second lifting unit 3. The second pallet 5 is arranged opposite to the first pallet 4, and a second makeshift space is provided between the second pallet 5 and the first pallet 4.

[0060] When the platform is stepped, passages are provided on both sides of the support platform 9, which extend to the docking platform 8. The support platform 9 can be placed in the first clearance space of the traction transport vehicle. The support platform 9 and the docking platform 8 cooperate to support the carriage 6 that is unloaded by the simultaneous descent of the first lifting unit 2 and the second lifting unit 3.

[0061] When the traction unit 1 transports the loaded carriage 6 to the docking platform 8, the traction unit 1 pulls the lifted carriage 6 to the docking platform 8. At this time, the traction unit 1 goes to the passage on both sides of the support platform 9, and the support platform 9 gives way to the first give way space of the traction transport vehicle, so that the carriage 6 arrives above the docking platform 8 and the support platform 9. The first lifting unit 2 and the second lifting unit 3 simultaneously drive the first pallet 4 and the second pallet 5 to descend, placing the carriage 6 on the docking platform 8 and the support platform 9, unloading the carriage 6, and then the traction unit 1 leaves to transport the next carriage 6. The traction unit 1 does not need to wait in place.

[0062] When the platform is sloped, when the traction unit 1 transports the loaded carriage 6 to the slope, the traction unit 1 pulls the lifted carriage 6 to the slope. At this time, the traction unit 1 moves up the slope until the entire carriage 6 can be placed on the slope. At this time, the first lifting unit 2 and the second lifting unit 3 simultaneously drive the first pallet 4 and the second pallet 5 to descend, placing the carriage 6 on the slope. The carriage 6 can be parked on the slope to ensure that the loaded materials do not slide down the slope. After unloading the carriage 6, the traction unit 1 then leaves and transports the next carriage 6. The traction unit 1 does not need to wait in place. Therefore, the carriage 6 of the present invention can be separated from the traction unit 1, making material loading convenient, improving transportation efficiency, and reducing material transportation costs.

[0063] In some examples, the height of the support platform 9 is consistent with the height of the docking platform 8, so that the carriage 6 is in a horizontal state when placed.
