[0002] Currently, container shipping has become an efficient logistics transportation mode that can be equipped with standard transportation equipment. As a core link in the modern logistics system, the efficiency of container shipping directly determines the turnover speed and overall cost of the supply chain.

[0003] The existing patent application publication number CN202624024U discloses a semi-trailer with a self-loading and unloading lifting mechanism, including a semi-trailer chassis, with a lifting mechanism installed at each end of the semi-trailer chassis. The lifting mechanism includes: a base clamped on the main beam of the semi-trailer chassis; a rotatable rotating seat installed on the base and a pin assembly to prevent the rotating seat from rotating during lifting; a folding arm crane assembly installed on the rotating seat; a bridge leg type support arm assembly installed on the rotating seat or a gantry type support arm assembly installed on both sides of the front and rear ends of the semi-trailer chassis; multiple turn locks that cooperate with the bottom holes of the container corner fittings are also provided on the frame of the semi-trailer chassis; a special lifting platform can also be configured in the middle of the upper part of the main beam of the semi-trailer chassis. This utility model can realize self-loading and unloading of goods on both sides of the semi-trailer chassis, which has good practicality, can effectively reduce the number of semi-trailers equipped on the tractor, improve transportation efficiency, and reduce transportation costs.

[0004] However, the lifting mechanism of this semi-trailer with a self-loading and unloading lifting mechanism is fixedly installed, and the position of the lifting mechanism cannot be adjusted according to the usage requirements. In addition, the lifting mechanism is installed at both ends, which occupies a lot of space and has a high cost, thus reducing the effectiveness of use.

[0005] The purpose of this utility model is to provide a self-loading and unloading container transport semi-trailer, which solves the problems of fixed installation of the hoisting mechanism, inability to adjust the position of the hoisting mechanism according to the usage requirements, and the large space occupied and high cost of hoisting mechanisms installed at both ends, which reduces the effectiveness of use. Utility Model Content

[0006] To achieve the above objectives, this utility model provides a self-loading and unloading container transport semi-trailer, including a semi-trailer body, a container transport compartment at the upper end of the semi-trailer body, a container loading and unloading component on one side of the container transport compartment, and hydraulic support components evenly distributed at the outer end of the semi-trailer body.

[0007] The container loading and unloading assembly includes a load-bearing mounting base. The load-bearing mounting base is provided on one side of the container transport vehicle. The upper end of the load-bearing mounting base is provided with a slide rail. An electric slide table is movably installed inside the slide rail. The electric slide table can drive the lifting equipment to move along the slide rail, so that the lifting equipment can completely cover the container transport vehicle. It eliminates the need to install two sets of lifting mechanisms, which can accurately adjust the loading and unloading point according to the actual placement of the container, and also reduces the space occupied and purchase cost.

[0008] The electric slide is equipped with a lifting arm at its upper end, and a telescopic arm is provided at the front end of the lifting arm. The telescopic arm can be extended and retracted to adjust the lifting position.

[0009] The lifting arm is equipped with an electric winch at one end, and a lifting wire rope is wound around the outer end of the electric winch. The lifting wire rope is connected to the end of the telescopic arm through a pulley, and a hook is provided at the end of the lifting wire rope. The lifting wire rope can be wound or unwound by the electric winch, which facilitates the loading and unloading of containers.

[0010] The hydraulic support assembly includes fixed seats. Four fixed seats are evenly arranged on the outer end of the semi-trailer body. A hydraulic telescopic rod is inserted through the middle of the four fixed seats, and the support seats can be moved by the hydraulic telescopic rod.

[0011] The lower telescopic end of the hydraulic telescopic rod is equipped with a support seat, and the lower end of the support seat is equipped with a shock-absorbing plate. The support seat and the shock-absorbing plate can be in contact with the ground under the drive of the hydraulic telescopic rod, which can provide stable support for the semi-trailer and prevent the semi-trailer from overturning.

[0012] This utility model discloses a self-loading and unloading container semi-trailer. Through the cooperation of the slide rail on the load-bearing mounting base and the electric slide table, the lifting arm can be moved flexibly along the slide rail, so that the lifting equipment can completely cover the container transport compartment. Unlike traditional semi-trailers, there is no need to install two sets of lifting mechanisms at both ends. This not only allows for precise adjustment of the loading and unloading points according to the actual placement of the container, but also reduces the space occupied and purchase costs. With the coordinated action of the lifting arm, telescopic arm and electric winch, container loading and unloading operations can be completed quickly. The electric winch, through the cooperation of the lifting wire rope and the pulley at the end of the telescopic arm, can quickly lift or lower the container. During lifting, the support base and shock-absorbing plate can be driven by the hydraulic telescopic rod to keep in contact with the ground, which can provide stable support for the semi-trailer, prevent the semi-trailer from overturning, and improve the loading and unloading efficiency of containers.

[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0020] Please see Figures 1-4 This utility model provides a technical solution: A self-loading and unloading container transport semi-trailer includes a semi-trailer body 1, a container transport compartment 2 is provided at the upper end of the semi-trailer body 1, a container loading and unloading component 3 is provided on one side of the container transport compartment 2, and hydraulic support components 4 are evenly provided at the outer end of the semi-trailer body 1.

[0021] In this embodiment, the preferred container loading and unloading assembly 3 includes a load-bearing mounting base 31. The load-bearing mounting base 31 is provided on one side of the container transport vehicle 2. The upper end of the load-bearing mounting base 31 is provided with a slide rail 32. An electric slide table 33 is movably installed inside the slide rail 32. The electric slide table 33 can drive the lifting equipment to move along the slide rail 32, so that the lifting equipment can completely cover the container transport vehicle 2. It is not necessary to install two sets of lifting mechanisms, which can accurately adjust the loading and unloading point according to the actual placement position of the container, and reduce the space occupied and purchase cost.

[0022] In this embodiment, the upper end of the preferred electric slide table 33 is provided with a lifting arm 34, and the front end of the lifting arm 34 is provided with a telescopic arm 35, which can be extended and retracted to adjust the lifting position.

[0023] In this embodiment, preferably, one end of the lifting arm 34 is provided with an electric winch 36, the outer end of the electric winch 36 is wound with a lifting wire rope 37, the lifting wire rope 37 is connected to the end of the telescopic arm 35 through a pulley, and the end of the lifting wire rope 37 is provided with a hook 38. The lifting wire rope 37 can be wound or unwound by the electric winch 36, which facilitates the loading and unloading of containers.

[0024] In this embodiment, the preferred hydraulic support assembly 4 includes a fixed seat 41. Four fixed seats 41 are evenly arranged at the outer end of the semi-trailer body 1. A hydraulic telescopic rod 42 is provided through the middle of the four fixed seats 41. The support seat 43 can be moved by the hydraulic telescopic rod 42.

[0025] In this embodiment, the lower telescopic end of the hydraulic telescopic rod 42 is preferably provided with a support seat 43, and the lower end of the support seat 43 is provided with a shock-absorbing plate 44. The support seat 43 and the shock-absorbing plate 44 can be in contact with the ground under the drive of the hydraulic telescopic rod 42, which can provide stable support for the semi-trailer and prevent the semi-trailer from overturning.

[0026] Working principle: Once the semi-trailer arrives at the container loading / unloading location, first activate the four hydraulic support components 4 at the outer end of the semi-trailer body 1. This causes the hydraulic telescopic rod 42 in the middle of the fixed seat 41 to extend downwards simultaneously, driving the support seat 43 and the lower shock-absorbing plate 44 to gradually approach the ground until all four shock-absorbing plates 44 are fully in contact with the ground and form a stable support. At this point, the semi-trailer body 1 remains level to prevent swaying during subsequent loading and unloading. Adjust the position of the container loading / unloading components 3 according to the actual placement of the container. Activate the electric slide 33 in the slide rail 32 on the load-bearing mounting seat 31. The electric slide 33 moves the upper lifting arm 34 along the slide rail 32 until the telescopic arm 35 at the front end of the lifting arm 34 aligns with the lifting point of the container. Then, stop the electric slide 33 and lock its position to ensure that the lifting arm 34 does not deviate during loading and unloading. Control the extension of the telescopic arm 35 at the front end of the lifting arm 34 so that the pulley at the end of the telescopic arm 35 approaches the lifting point of the container. Simultaneously, activate one end of the lifting arm 34. The electric winch 36 releases the hoisting wire rope 37 wound at its outer end. The hoisting wire rope 37 hangs down along the pulley at the end of the telescopic boom 35. The operator hooks the end hook 38 onto the container lifting point and locks it. The electric winch 36 is then started in reverse to retract the hoisting wire rope 37. The container is slowly lifted by the pulley block until the bottom of the container is higher than the top of the container truck 2, avoiding collision between the container and the truck 2 during the lifting process. Then the container is slowly lowered and placed smoothly into the container truck 2. After the container is loaded and unloaded, the telescopic boom 35 is first controlled to retract into the hoisting boom 34. Then the electric slide 33 is started to move the hoisting boom 34 to the end of the slide rail 32 to avoid occupying too much space during the journey. Finally, the hydraulic telescopic rods 42 of the four hydraulic support components 4 are controlled to retract, so that the support base 43 and the shock absorber 44 are lifted off the ground. The semi-trailer resumes driving and waits to enter the next transportation stage.

[0027] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
