Description

Technical Field

[0001] This utility model relates to the field of box vehicle transportation technology, and in particular to a box vehicle with an intermediate lifting platform. Background Technology

[0002] Box trucks are specialized transport vehicles equipped with enclosed compartments, and are widely used in logistics, express delivery, cold chain, and dangerous goods transportation.

[0003] Many existing box trucks on the market lack internal partitions, making it difficult to transport certain goods (such as bicycles, electric bikes, and other items that cannot be stacked; packaging each item individually in wooden crates would incur significant labor and material costs, and unpacking at the destination would be extremely inconvenient). Although some box trucks have fixed intermediate partitions, these partitions limit the transport of other stackable or large items. Therefore, there is an urgent need in the market for a box truck with an intermediate lifting platform to solve this problem. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing a box vehicle with a middle lifting platform. The middle lifting platform is used in box transport vehicles, which is inexpensive and has a clever motor and wire rope drive structure. It is very convenient to operate remotely and solves the problem of layered transportation of goods. At the same time, it is convenient to pick up and put down, which expands the transportation function of traditional box vehicles and has good economic benefits and promotion value.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A van with a central lifting platform includes a van body and a central lifting platform body. Multiple supporting channel steels are symmetrically arranged at equal intervals on the left and right sides of the van body, with the openings of the supporting channel steels facing inwards. The left and right sides of the central lifting platform body abut against the opposite side walls of the multiple supporting channel steels. Each of the multiple supporting channel steels has multiple limiting holes at equal intervals in the height direction. The central lifting platform body is fixed between the multiple supporting channel steels by pin assemblies passing through the corresponding limiting holes. Each of the multiple supporting channel steels contains steel wire ropes and multiple pulleys. A drive mechanism is installed at the bottom of the van body. One end of each steel wire rope is fixed to the central lifting platform body, and the other end passes over the top pulley, down through the bottom plate of the van body, and is fixed to the drive mechanism. The drive mechanism controls the multiple steel wire ropes to synchronously retract and expand, causing the central lifting platform body to rise and fall horizontally.

[0007] Preferably, the pin assembly includes a pin body and a type B resilient cotter pin. The pin body passes through a corresponding limiting hole and is designed in the shape of a "7". The type B resilient cotter pin is plugged into and pulled onto the other side of the pin body.

[0008] Preferably, the pulley is provided with a base, and the pulley is installed in the support channel steel through the base.

[0009] Preferably, the drive mechanism includes a remote-controlled electric reel driver mounted on the bottom plate of the compartment. The remote-controlled electric reel driver is equipped with a remote control operation module. Multiple reel bodies are mounted on both sides of the output end of the remote-controlled electric reel driver, and the ends of the wire ropes are respectively wound around the corresponding reel bodies.

[0010] Preferably, the output ends of the remote-controlled electric reel driver rotate in opposite directions.

[0011] Preferably, bearing seats are provided at the ends of the reel bodies on both the left and right sides, and the reel bodies are mounted on the bottom plate of the housing via the bearing seats.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. This van with a central lifting platform can control the raising and lowering of the central platform to different heights by remotely operating the electric reel drive to retract and release the steel wire rope, which can meet the needs of transporting goods that are not tall but cannot be stacked. At the same time, in order to prevent the central lifting platform from accidentally falling due to the broken steel wire rope and causing accidents, multiple pins are also installed under the platform for reliable locking. In addition, when not in use or when transporting large items, the central lifting platform can be lowered and placed on the floor of the van, which is conducive to the flexible use of the van space.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figures 1-5 A van with a central lifting platform, as shown in the reference. Figure 1 The system includes a box body 1 and a central lifting platform body 4. Multiple supporting channel steels 5 are symmetrically arranged at equal intervals on the left and right sides of the box body 1. The supporting channel steels 5 are vertically arranged and welded inside the box body 1, and the supporting channel steels 5 on the left and right sides are symmetrically arranged. The number of supporting channel steels 5 is matched according to the length of the box body 1. The openings of the supporting channel steels 5 face the inside of the box body 1. The left and right sides of the central lifting platform body 4 abut against the side walls of the multiple supporting channel steels 5 respectively. Specifically, the two ends of the central lifting platform body 4 are provided with protrusions extending into the supporting channel steels 5, so that the supporting channel steels 5 can serve as supports and vertical sliding tracks for the central lifting platform body 4, so that the central lifting platform body 4 can remain stable in a horizontal state during vertical movement. At the same time, the multiple supporting channel steels 5 can play a certain role in strengthening the overall strength of the box body 1.

[0022] Reference Figure 1 , Figure 3 and Figure 4 Multiple supporting channel steels 5 are provided with multiple limiting holes at equal intervals in the height direction. The middle lifting platform body 4 is fixed between the multiple supporting channel steels 5 by a pin assembly passing through the corresponding limiting holes. The pin assembly includes a pin body 6 and a type B elastic cotter pin 7. The pin body 6 passes through the corresponding limiting hole and abuts against the bottom of the middle lifting platform body 4, providing support for the middle lifting platform body 4 and preventing it from falling. The pin body 6 is designed in the shape of a "7" for easy operation. The type B elastic cotter pin 7 is inserted and removed from the other side of the pin body 6 to prevent the pin body 6 from accidentally coming out. The type B elastic cotter pin 7 can be easily inserted or removed from the pin without the use of any tools.

[0023] Reference Figure 2 and Figure 5Each of the multiple supporting channel steels 5 contains a steel wire rope 3 and multiple pulleys 2. The steel wire rope 3 and multiple pulleys 2 are arranged in the internal space of the supporting channel steel 5 so that the steel wire rope 3 will not be caught on other objects. The pulley 2 is equipped with a base and is installed in the supporting channel steel 5 through the base, so that the steel wire rope 3 can change direction and slide better. The pulleys 2 are arranged vertically and horizontally according to the position of the steel wire rope 3, so that the steel wire rope 3 can turn in multiple vertical directions, which is beneficial for winding and unwinding. A drive mechanism is installed at the bottom of the box body 1. One end of the steel wire rope 3 is fixed to the middle lifting platform body 4, and the other end passes through the pulley 2 at the top, passes down through the bottom plate of the box body 1, and is fixed to the drive mechanism, so that the middle lifting platform body 4 can be driven to move up and down by the steel wire rope 3. The drive mechanism controls the multiple steel wire ropes 3 to retract and unfold synchronously, so that the middle lifting platform body 4 rises and falls horizontally.

[0024] Reference Figure 5 The drive mechanism includes a remote-controlled electric reel driver 9 mounted on the floor of the compartment 1. The remote-controlled electric reel driver 9 is a 24V remote-controlled electric reel driver, which can use the vehicle's 24V power supply. The remote-controlled electric reel driver 9 is equipped with a remote control operation module for easy operation and positioning. Multiple reel bodies 10 are mounted on both sides of the output end of the remote-controlled electric reel driver 9. The multiple reel bodies 10 rotate coaxially with the corresponding output end of the remote-controlled electric reel driver 9. The two output ends of the remote-controlled electric reel driver 9 rotate in opposite directions (achieved through an internal gearbox), ensuring the synchronicity of the winding and unfolding of multiple wire ropes 3. This allows the intermediate lifting platform body 4 to remain horizontal during the rising and falling process, preventing the intermediate lifting platform body 4 from tilting and causing lifting jams, or even causing accidents such as cargo overturning.

[0025] The ends of the wire ropes 3 are respectively wound around the corresponding reel bodies 10. Specifically, the wire ropes 3 passing through the bottom plate from the top of the left compartment 1 are connected to the corresponding reel bodies 10 on the left through multiple sets of pulleys 2 on the left. The wire ropes 3 passing through the bottom plate from the top of the right compartment 1 are connected to the corresponding reel bodies 10 on the right through multiple sets of pulleys 2 on the right. This allows the remote-controlled electric reel driver 9 to drive the multiple reel bodies 10 to rotate, thereby synchronously winding the multiple wire ropes 3. This, in turn, enables the middle lifting platform body 4 to rise and fall stably. The ends of the reel bodies 10 on both the left and right sides are equipped with bearing seats 8. The reel bodies 10 are mounted on the bottom plate of the compartment 1 through the bearing seats 8, which can better support the left and right reel bodies 10, ensure their stability, and prevent them from falling.

[0026] The functional principle of this utility model can be explained through the following operation methods:

[0027] In this utility model, the remote-controlled electric reel driver 9 is connected to the chassis battery via a cable (considering that it is used very infrequently, only once for loading and once for unloading during a single transport trip, so no additional battery is provided to save on the cost of the entire device). The lifting of the intermediate lifting platform body 4 is operated from outside the vehicle using the remote control that comes with the remote-controlled electric reel driver 9.

[0028] In use, the remote-controlled electric reel driver 9 drives multiple reel bodies 10 to rotate. The multiple reel bodies 10 on both sides rotate in opposite directions, synchronously winding multiple steel wire ropes 3. This allows the intermediate lifting platform body 4 to be raised from the bottom of the compartment 1 to its highest point. The locking pin body 6 and the type B elastic cotter pin 7 are then inserted to support and fix the intermediate lifting platform body 4, ensuring safety and preventing it from falling. First, all the goods are loaded at the bottom. Then, the locking pin body 6 and the type B elastic cotter pin 7 are removed and inserted into the intermediate lifting platform body 4 at the predetermined height position on the support channel steel 5. Then, the intermediate lifting platform body 4 is lowered to press the locking pin body 6 to support it. Goods for the upper layer can then be loaded onto the intermediate lifting platform body 4. The unloading process is the reverse of the above steps.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
