A baggage transport vehicle

Abstract

This invention discloses a baggage transport vehicle, belonging to the field of baggage transportation. It includes a baggage assembly vehicle with an assembly mechanism at its bottom for assembling and stabilizing multiple baggage assembly vehicles. A stacking unit is located on the top of the baggage assembly vehicle for stacking and stabilizing baggage. This invention facilitates convenient stacking by pre-placing stacking supports on top of the baggage assembly vehicle before placing baggage on it, and then placing the baggage to be transported between adjacent stable stacking plates. Furthermore, when baggage needs to be transported to the aircraft cargo hold, a transport conveyor lifts the baggage within the arc-shaped retrieval track, and then places subsequent baggage on top of the conveyor belt for convenient retrieval. This avoids transport personnel spending excessive time on baggage stacking and arrangement, thus improving baggage transportation efficiency.

Description

Technical Field

[0001] This invention relates to the field of baggage transportation technology, and more particularly to a baggage transport vehicle. Background Technology

[0002] As people's living standards continue to improve, the number of passengers choosing air travel for long-distance trips continues to grow, leading to a new high in baggage transportation volume and increasing demands for speed and efficiency in baggage transportation.

[0003] Currently, baggage transport vehicles used at airports are divided into baggage conveyor trucks and baggage trolleys. When loading baggage, the baggage placed on the baggage trolley is placed on the baggage conveyor truck, and then the baggage transported to the aircraft cargo hold is arranged to ensure the safety of the baggage in the cargo hold while improving the space utilization of the cargo hold. When retrieving baggage, transport personnel need to move the suitcases out one by one. This baggage transport method requires a lot of time for stacking, resulting in low transport efficiency, high labor intensity, and the possibility of damage due to the stacked baggage being squeezed against each other.

[0004] Therefore, a baggage transport vehicle is proposed. Summary of the Invention

[0005] The purpose of this invention is to solve the problems of low baggage transportation efficiency, high labor intensity, and potential damage caused by stacked baggage due to mutual compression when using baggage transport vehicles currently used in airports.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A baggage transport vehicle includes a baggage assembly vehicle for transporting baggage. The baggage assembly vehicle uses a baggage trailer as its power source. An assembly mechanism is provided at the bottom of the baggage assembly vehicle. The assembly mechanism is used to splice and stabilize multiple baggage assembly vehicles.

[0008] The luggage assembly vehicle is equipped with a stacking unit on its top. The stacking unit consists of a stacking mechanism and a stabilizing mechanism. The stacking mechanism is used to stack luggage, and the stabilizing mechanism is used to stabilize the top of the stacking mechanism.

[0009] Preferably, the assembly mechanism includes an assembly locking sleeve disposed on the outside of the luggage assembly vehicle and an assembly splicing groove opened at the bottom of the luggage assembly vehicle. The assembly locking sleeve is fixed to the inner wall of the assembly splicing groove by a fixing connecting rod. Multiple assembly locking sleeves are limited by locking bolts. A towing column is provided on the front of the luggage assembly vehicle.

[0010] Preferably, the top of the fixed connecting rod is slidably connected to an angle stabilizing disc that is sleeved with a locking bolt, and the bottom of the angle stabilizing disc is provided with a rotation limiting groove.

[0011] Preferably, the stacking mechanism includes a luggage stacking baffle disposed on the top of the luggage assembly vehicle, and a stacking assembly is slidably connected to the inner wall of the luggage stacking baffle. The stacking assembly consists of a stacking bracket and a sliding limit locking block, and the stacking bracket is slidably connected to the sliding limit locking block through a stacking locking post.

[0012] Preferably, the stacking bracket is slidably connected to a luggage stacking stabilizing clamp on opposite sides. The luggage stacking stabilizing clamp is slidably connected to the inner wall of the stacking bracket via an elastic component, and the two luggage stacking stabilizing clamps with a tendency to move away from each other are provided with mutually attractive stabilizing magnets inside.

[0013] Preferably, the stacking locking post is slidably disposed inside the stacking bracket, and the inner wall of the luggage stacking baffle is provided with a stacking sliding track, which consists of a vertical stacking track and an arc-shaped retrieval track, and the bottom of the arc-shaped retrieval track is connected to the top of the vertical stacking track.

[0014] Preferably, the stabilizing mechanism includes an adjustable support base plate rotatably mounted on the top of the luggage assembly vehicle and a luggage stabilizing buckle plate mounted on the top of the luggage assembly vehicle. The rotation angle of the adjustable support base plate is controlled by an adjusting assembly consisting of an adjusting screw and an adjusting wedge slider. The tilt angle of the luggage stabilizing buckle plate is controlled by a combined hydraulic cylinder.

[0015] Preferably, the edge of the luggage assembly vehicle is provided with an adjustment groove that is threadedly connected to the adjustment screw, and the adjustment wedge slider is slidably connected to the adjustment support base plate.

[0016] Preferably, the combined hydraulic cylinder controls the internal hydraulic pressure through a hydraulic control component, which consists of an electric screw, a hydraulic regulating sleeve, and a hydraulic control slide. The electric screw is driven by a servo motor, and the combined hydraulic cylinder divides the internal space into a stabilizing drive chamber and a picking drive chamber through the hydraulic control slide. The picking drive chamber is slidably connected to a picking push plate through a picking push rod.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. Addressing the issue raised above regarding the low efficiency of current airport baggage transport vehicles, which require significant time for staff to stack and arrange baggage, this invention utilizes a combination of stacking supports, sliding limit locking blocks, and stacking locking posts. When baggage is to be placed on the baggage assembly vehicle, the interactive limit locking blocks slide against the inner wall of the baggage stacking baffle, allowing the stacking supports to be placed on top of the vehicle. The baggage to be transported is then placed between adjacent stable stacking plates, facilitating convenient stacking. Furthermore, when baggage needs to be transported to the aircraft cargo hold, a transport conveyor lifts the baggage along the curved retrieval track, allowing subsequent baggage to be placed on top of the conveyor belt for easy retrieval. This significantly reduces the time spent by staff on stacking and arranging baggage, thereby improving baggage transport efficiency.

[0019] 2. Regarding the aforementioned issue that stacked luggage may be damaged due to mutual compression during the transportation of luggage in airport baggage transport vehicles, a device is installed that combines stacking supports, luggage stacking stabilizing clamps, and elastic components. After the luggage is stably clamped into the stacking support by the luggage stacking stabilizing clamps, stabilizing magnets are used to stabilize the non-clamping surfaces of the luggage stacking stabilizing clamps and stabilize the stacking support. Furthermore, during the stacking process, the luggage stacking stabilizing clamps contact each other instead of large-area contact between luggage, thereby avoiding damage caused by mutual compression of luggage stacked on top of each other.

[0020] 3. By using a combination of assembly locking sleeves, locking bolts, and angle stabilizing discs, the number of luggage assembly carts to be assembled is selected based on the amount of luggage to be transported. The assembly splicing slots of the luggage assembly carts are then positioned opposite each other, so that multiple assembly locking sleeves fit together to form a rotating hole that connects with the locking bolt. The locking bolt is then locked by the nut washer at the bottom of the locking bolt, thus completing the convenient assembly process of the luggage assembly cart.

[0021] 4. By employing a combination of luggage stabilizing buckles, hydraulic cylinders, and a lifting pusher, the system works in tandem with various mechanisms. When luggage needs to be secured and stabilized, a servo motor is activated to rotate the electric screw, increasing the hydraulic pressure in the stabilizing drive chamber and decreasing the hydraulic pressure in the lifting drive chamber. This causes the luggage stabilizing buckle to rotate downwards, securing the luggage on top, and the lifting pusher to move away from the luggage, ensuring stability during transport. Conversely, when luggage needs to be retrieved, the servo motor is activated to rotate the electric screw in the opposite direction, causing the luggage stabilizing buckle to rotate upwards and the lifting pusher to move closer to the luggage, suspending the luggage on top of the luggage assembly vehicle. This achieves both secure securing and easy retrieval of the luggage. Attached Figure Description

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0031] Reference Figures 1-7A baggage transport vehicle includes a baggage assembly vehicle 1 for transporting baggage. The baggage assembly vehicle 1 uses a baggage trailer as its power source. An assembly mechanism is provided at the bottom of the baggage assembly vehicle 1. The assembly mechanism is used to splice and stabilize multiple baggage assembly vehicles 1. A stacking unit is provided at the top of the baggage assembly vehicle 1. The stacking unit consists of a stacking mechanism and a stabilizing mechanism. The stacking mechanism is used to stack baggage, and the stabilizing mechanism is used to stabilize the top of the stacking mechanism.

[0032] Through the above technical solution, the luggage assembly vehicle 1 can select the appropriate quantity of luggage to be transported as needed, and provide power to the assembled luggage assembly vehicle 1 by connecting the luggage trailer to the towing column.

[0033] like Figure 2 As shown, the assembly mechanism includes an assembly locking sleeve 11 located on the outside of the luggage assembly vehicle 1 and an assembly splicing groove 12 located at the bottom of the luggage assembly vehicle 1. The assembly locking sleeve 11 is fixed to the inner wall of the assembly splicing groove 12 by a fixing connecting rod 111. Multiple assembly locking sleeves 11 are limited by locking bolts 13. A traction column is provided on the front of the luggage assembly vehicle 1.

[0034] Through the above technical solution, the top of the fixed connecting rod 111 is slidably connected to an angle stabilizing disc 14 that is sleeved with the locking bolt 13, and the bottom of the angle stabilizing disc 14 is provided with a rotation limiting groove 141.

[0035] Based on the above, the assembly splicing groove 12 is arc-shaped, and the rotation limiting groove 141 is composed of left and right fixed grooves and front and rear rotation limiting arc grooves. The left and right fixed grooves fix the rotation angle of the luggage assembly cart 1 assembled on the left and right, and the front and rear rotation limiting arc grooves limit the rotation angle of the luggage assembly cart 1 assembled at intervals, so as to ensure that the luggage assembly cart 1 can swing but will not collide with each other, thereby ensuring that the luggage assembly cart 1 can be transported stably.

[0036] Further based on the above, the assembly locking sleeves 11 of the luggage assembly cart 1 to be assembled are fitted together to form a rotating hole that is rotatably connected to the locking bolt 13. Then, the locking bolt 13 is locked in the rotating hole by the nut washer provided at the bottom of the locking bolt 13, thus serving as the assembly rotation center of the luggage assembly cart 1, and completing the assembly process of the luggage assembly cart 1.

[0037] like Figure 4 and Figure 5 As shown, the stacking mechanism includes a luggage stacking baffle 2 disposed on the top of the luggage assembly vehicle 1. A stacking component 3 is slidably connected to the inner wall of the luggage stacking baffle 2. The stacking component 3 consists of a stacking bracket 31 and a sliding limit locking block 32. The stacking bracket 31 is slidably connected to the sliding limit locking block 32 through a stacking locking post 33.

[0038] Through the above technical solution, a baggage stacking stabilizing clamp 311 is slidably connected to the opposite side of the stacking bracket 31. The baggage stacking stabilizing clamp 311 is slidably connected to the inner wall of the stacking bracket 31 through an elastic component 312. The two baggage stacking stabilizing clamps 311 with a tendency to move away from each other are provided with mutually attractive stabilizing magnets 313 inside. Thus, when baggage is stacked in the aircraft cargo hold, the baggage stacked by the stacking bracket 31 is stabilized by the mutual attraction of the attached stabilizing magnets 313.

[0039] Based on the above, the stacking locking post 33 is slidably disposed inside the stacking bracket 31, and the inner wall of the luggage stacking baffle 2 is provided with a stacking sliding track. The stacking sliding track consists of a vertical stacking track 21 and an arc-shaped retrieval track 22, and the bottom of the arc-shaped retrieval track 22 is connected to the top of the vertical stacking track 21.

[0040] Furthermore, the luggage stacking baffle 2 is divided into front and rear stacking limiting baffles and supporting side plates. The vertical stacking rail 21 and the arc-shaped retrieval rail 22 are opened on the inner wall of the front and rear stacking limiting baffles. When the luggage conveyor transports luggage by the conveyor belt, by placing the stacking bracket 31 in the arc-shaped retrieval rail 22, the luggage suspended in the air can be lifted by the top of the conveyor belt to generate transport power, and drive the subsequent stacking brackets 31 to move to the top of the conveyor belt one by one, so as to complete the convenient retrieval operation of the luggage during the transportation process.

[0041] like Figure 3 As shown, the stabilizing mechanism includes an adjustable support base plate 4 rotatably mounted on the top of the luggage assembly vehicle 1 and a luggage stabilizing buckle plate 5 mounted on the top of the luggage assembly vehicle 1. The rotation angle of the adjustable support base plate 4 is controlled by an adjusting assembly, which consists of an adjusting screw 41 and an adjusting wedge slider 42. The tilt angle of the luggage stabilizing buckle plate 5 is controlled by a combined hydraulic cylinder 51.

[0042] Through the above technical solution, the edge of the luggage assembly vehicle 1 is provided with an adjustment groove that is threadedly connected to the adjustment screw 41, and the adjustment wedge slider 42 is slidably connected to the adjustment support base plate 4.

[0043] Based on the above, after all the luggage is stably clamped between the stacking brackets 31, the adjusting screw 41 is rotated to drive the adjusting wedge slider 42 to press the adjusting support base plate 4, causing the adjusting support base plate 4 to rotate upward, so that the stacked luggage is placed at an angle on the top of the luggage assembly vehicle 1, thereby the luggage has a tendency to slide towards the side plate of the luggage stacking baffle 2 by its own weight, thus improving the stability of the luggage during transportation.

[0044] like Figure 6As shown, the combined hydraulic cylinder 51 controls the internal hydraulic pressure through a hydraulic control component, which consists of an electric screw 52, ​​a hydraulic regulating sleeve 53, and a hydraulic control slide 54. The electric screw 52 is driven by a servo motor 521. The combined hydraulic cylinder 51 divides its internal space into a stable drive chamber and a pick-up drive chamber through the hydraulic control slide 54. The pick-up drive chamber is slidably connected to a pick-up push plate 56 through a pick-up push rod 55.

[0045] With the above technical solution, when luggage needs to be unloaded from luggage assembly vehicle 1, the servo motor 521 is started to drive the electric screw 52 to rotate in the opposite direction, so that the luggage stabilizing buckle 5 rotates upward and drives the picking push plate 56 to push the stacking bracket 31 placed on the top outward, so that the luggage placed on the top is suspended outside the luggage assembly vehicle 1, which makes it easier for the transport conveyor belt of the luggage conveyor to lift the bottom of the suspended luggage. Through the friction between the bottom of the luggage and the transport conveyor belt, the subsequent stacking brackets 31 are driven to be lifted to the top of the transport conveyor belt in sequence, so that they move linearly and complete the unloading operation of luggage during transportation.

[0046] Based on the above, when luggage is placed between luggage stacking stabilizing clamps 311, the luggage stacking stabilizing clamps 311 are placed horizontally and the luggage stabilizing buckle 5 is in an upward flipped state. After all the luggage is placed, the luggage is tilted upward by rotating the adjusting screw 41, and at the same time, the servo motor 521 is started to drive the luggage stabilizing buckle 5 to rotate downward, and the lifting push plate 56 is moved towards the side plate of the luggage stacking baffle 2. When the stacking bracket 31 placed on the top is tilted and attached to the lifting push plate 56, the luggage placed on the top is fastened and stabilized without affecting the normal placement of the luggage.

[0047] Working principle:

[0048] First, when placing luggage on top of luggage assembly cart 1, the luggage assembly cart 1 to be used is pre-assembled into a whole by the assembly mechanism. The assembly process is as follows: the assembly locking sleeves 11 of the luggage assembly cart 1 to be assembled are fitted together to form a rotating hole that is rotatably connected to the locking bolt 13. Then, the locking bolt 13 is locked in the rotating hole by the nut washer set at the bottom of the locking bolt 13. The swing angle of the luggage assembly cart 1 assembled in front and behind is limited by the angle stabilizing disc 14 set at the top of the locking bolt 13 to prevent the luggage from falling off when being towed by the luggage trailer.

[0049] Secondly, when luggage is placed on luggage assembly vehicle 1 via stacking bracket 31, an adjustable luggage placement slot is formed by stacking mechanism, which can stabilize the upper and lower sides of luggage. The stacking stabilization process is as follows: stacking bracket 31 is slidably connected to luggage stacking baffle 2 via sliding limit locking block 32 and placed on top of luggage assembly vehicle 1. Then, luggage placement slot is formed by upper and lower adjacent luggage stacking stabilizing clamps 311. Then, luggage is placed between upper and lower adjacent luggage stacking stabilizing clamps 311 to clamp and stabilize it during the stacking process.

[0050] Based on the above, a sliding groove is provided on the inner wall of the stacking bracket 31 and the sliding limit locking block 32 for the stacking locking post 33 to slide and be limited. The inner wall of the sliding limit locking block 32 limits the stacking locking post 33 that slides in the two adjacent stacking brackets 31, so that the multiple stacking brackets 31 form a whole. This makes it convenient to stack or move multiple pieces of luggage as a whole when stacking or transporting them. Furthermore, the stabilizing magnet 313 can stabilize the position of the adjacent stacking brackets 31 when the luggage is placed vertically in the aircraft cargo hold, thereby achieving the effect of stabilizing the stacking of luggage while facilitating stacking.

[0051] Then, during the transportation of luggage by towing the luggage assembly vehicle 1 by the luggage trailer, it is necessary to stabilize the luggage during transportation. The stabilization process is as follows: after all the luggage is stably clamped between the stacking brackets 31, the adjusting screw 41 is rotated to drive the adjusting wedge slider 42 to press the adjusting support base plate 4, which in turn drives the adjusting support base plate 4 to rotate upward, so that the stacked luggage is tilted and placed on the top of the luggage assembly vehicle 1. Thus, the luggage has a tendency to slide towards the side plate of the luggage stacking baffle 2 due to its own weight, thereby improving the stability of the luggage during transportation. During this period, the servo motor 521 drives the electric screw 52 to rotate, increasing the hydraulic pressure in the stabilizing drive chamber, so that the luggage stabilizing buckle 5 is pressed down, pressing down and fitting the luggage clamped in the top stacking bracket 31, further improving the stability of the luggage during transportation.

[0052] Based on the above, when it is necessary to unload luggage from luggage assembly vehicle 1, the servo motor 521 is started to drive the electric screw 52 to rotate in the opposite direction, so that the luggage stabilizing buckle 5 rotates upward and drives the picking push plate 56 to push the stacking bracket 31 placed on the top outward, so that the luggage placed on the top is suspended outside the luggage assembly vehicle 1, which makes it easier for the transport conveyor belt of the luggage conveyor to lift the bottom of the suspended luggage. Through the friction between the bottom of the luggage and the transport conveyor belt, the subsequent stacking brackets 31 are driven to be lifted to the top of the transport conveyor belt in sequence, so that they move linearly and complete the unloading operation of luggage during transportation.

[0053] Furthermore, when luggage is placed between the luggage stacking stabilizing clamps 311, the luggage stacking stabilizing clamps 311 are placed horizontally and the luggage stabilizing buckle 5 is in an upward flipped state. After all the luggage is placed, the luggage is tilted upward by rotating the adjusting screw 41, and at the same time, the servo motor 521 is started to drive the luggage stabilizing buckle 5 to rotate downward. When the stacking bracket 31 placed on the top tilts and fits against the take-up push plate 56, the luggage placed on the top is fastened and stabilized without affecting the normal placement of the luggage.

[0054] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
