Description

Technical Field

[0001] The present invention relates to the technical field of container fixing devices, and specifically to a high-speed rail logistics container fixing device. Background Art

[0002] High-speed rail logistics utilizes spaces such as the high-speed express cabinets of high-speed rail passenger EMUs, large luggage storage areas, and the space behind the last row of seats in the second-class carriages to transport high-speed rail express parcels. When transporting goods, the goods are generally packed in containers, and then the containers are fixed in the carriages of rail transit vehicles such as high-speed rails to ensure safety during transportation.

[0003] Currently, most high-speed rail express parcels are placed in the space behind the last row of seats in the second-class carriage, and the movement of the container is restricted by the space between the carriage side wall and the seat backrest, without any equipment for fixing the container. This simple placement method is prone to safety hazards such as movement, collision, slipping, and tilting in the face of railway emergencies, especially for transporting high-value precision express parcels, which cannot meet the requirements.

[0004] Chinese Patent CN202022476683.1 discloses "a high-speed rail logistics container fixing device", which includes a carriage floor, a first fixing seat, and a second fixing seat. A T-shaped chute is opened at the top of the carriage floor, and multiple groups of fixing threaded holes are equidistantly arranged on the carriage floor on both sides of the T-shaped chute. A first fixing seat and a second fixing seat are arranged on the top of the T-shaped chute. A first T-shaped slider is arranged at the bottom of the first fixing seat, and first fixing through holes are opened on both sides of the first fixing seat. First fixing bolts are arranged in the first fixing through holes. A connecting frame is arranged on the top of the first fixing seat, a rotating shaft is arranged between the connecting frames, a fixing steel cable is wound around the rotating shaft, one end of the rotating shaft passes through the connecting frame and is fixedly connected to a rotating disk, the other end of the rotating shaft passes through the connecting frame and is fixedly connected to a ratchet wheel, and a pawl is arranged on one side of the ratchet wheel.

[0005] This fixing device has a certain effect of fixing the container, but due to its structural limitations, first, it occupies a large amount of ground space; second, it is not easy to disassemble; third, it can only fix a single container and cannot meet the transportation conditions of multiple containers, and cannot adapt to the increasing demand for high-speed rail express volume. Summary of the Invention

[0006] The object of the present invention is to solve the problems raised in the above background art, and proposes a high-speed rail logistics fixing device that is easy to disassemble, saves space, and can fix multiple containers at the same time.

[0007] The object of the present invention is achieved through the following technical solutions.

[0008] A fixing device for high - speed rail logistics container, installed inside the carriage of a high - speed rail EMU, includes a first mounting frame, a second mounting frame, a sliding rod, a telescopic rod, a limiting component, and a connecting component. The two mounting frames are fixedly installed on the side of the carriage, with the first mounting frame close to the top of the carriage and the second mounting frame close to the bottom of the carriage; the upper end of the sliding rod is movably installed on the first mounting frame at the top of the carriage, and the lower end is movably installed on the second mounting frame at the top of the carriage. The connecting component is movably installed on the sliding rod; the rear end of the telescopic rod is movably installed on the second mounting frame at the bottom of the carriage, and the limiting component is fixedly installed at the front end of the telescopic rod. One sliding rod and two telescopic rods form a set of fixing units; a steel cable is wound inside the connecting component, and the steel cable can extend out of the connecting component to cooperate with the limiting component.

[0009] The limiting component includes an abutting part and a limiting part. The limiting part is a steel plate with a pin. The abutting part is fixedly installed at the front end of the telescopic rod. There is a surrounding cable - winding groove on the abutting part for cooperating with the steel cable of the connecting component; there is a groove at the top end of the abutting part, which can fit on the first mounting frame when not in use; there is also a through - hole in the middle of the abutting part, and the pin of the limiting part is inserted into this through - hole to form a rotatable connection with the abutting part.

[0010] The connecting component includes an installation shell, a winding rod, a rotating motor, two transmission wheels, a transmission belt, a steel cable, a hook, a buffer, and a mounting plate; the installation shell is movably connected to the sliding rod through two ear - like parts with holes passing through the sliding rod. The installation shell is a cavity structure. The winding rod is installed inside the installation shell. One end of the steel cable is wound on the winding rod, and the other end is provided with a hook; the rotating motor is fixedly installed on the upper wall surface of the installation shell with the mounting plate; the two transmission wheels are respectively fixedly installed on the winding rod and the output shaft of the rotating motor; the transmission belt is sleeved on the two transmission wheels. There is an installation groove connected to the inside of the installation shell, and the inner edge of the top surface of the installation groove is a chamfer. The buffer is detachably installed in the installation groove, and the end of the steel cable with the hook passes through the buffer. There are connecting hanging rings on the buffer that can cooperate with the hook. The connecting hanging rings are symmetrically arranged on the buffer so that the user can choose to connect the steel cable or the hook with the connecting hanging rings in any direction.

[0011] The usage method of the fixing device for high - speed rail logistics container of the present invention is as follows:

[0012] First, adjust the distance between the two telescopic rods. The size of the distance depends on the size of the container to be fixed. Then, move the container between the two telescopic rods so that the two limiting components are in contact with the opposite side surfaces of the container. Then, adjust the connecting component on the sliding rod so that it is in contact with the top of the container. Then, extend the steel cable out of the connecting component and pull the buffer member so that the steel cable cooperates with the two limiting components. At this time, the two limiting components clamp and fix the side surfaces of the container, and the connecting component fixes the top of the container. The steel cable extends into the cable winding grooves on the contact members at the front ends of the left and right telescopic rods and cooperates with the contact members in sequence, and then the hook at the front end of the steel cable is fixed on the connecting hanging ring on the right side of the buffer member. Start the motor to contract the steel cable so that the connecting component cooperates with the two limiting components to prevent vibration during the high-speed train operation from causing the separation of the limiting components, the connecting component and the container. Generally speaking, by setting the steel cable to connect the connecting component and the limiting component, the container can be fixed. Generally, one container is placed in one set of fixing units. When two or more containers of the same type are stacked and the height does not exceed the height between the bottom of the high-speed multiple unit carriage and the bottom edge of the installation shell, they can be stacked and fixed with one set of fixing units. Compared with the prior art, by loosening or tightening the steel cable on one side and moving and adjusting the sliding rod and the telescopic rod, multiple containers can be fixed more reasonably.

[0013] The present invention greatly increases the number of containers fixed by the fixing device, and can fix multiple containers more reasonably. The device has a simple structure, can effectively reduce the overall floor area, is convenient for disassembly and carrying, is easy to use, and is suitable for large-scale popularization and application.

Detailed implementation mode

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Refer to the attached Figures 1-6 , the fixed device for the high-speed rail logistics container is installed in the carriage and includes a first mounting bracket 1, a second mounting bracket 1-1, a sliding rod 2, a telescopic rod 3, a limiting component 4, and a connecting component 7. The two mounting brackets are fixedly installed on the side of the carriage, and the first mounting bracket 1 is close to the top of the carriage, and the second mounting bracket 1-1 is close to the bottom of the carriage; the upper end of the sliding rod 2 is movably installed on the first mounting bracket 1 at the top of the carriage, and the lower end is movably installed on the second mounting bracket 1-1 at the bottom of the carriage, and the connecting component 7 is movably installed on the sliding rod 2; the rear end of the telescopic rod 3 is movably installed on the second mounting bracket 1-1 at the bottom of the carriage, the limiting component 4 is fixedly installed at the front end of the telescopic rod 3, and one sliding rod 2 and two telescopic rods 3 form a set of fixing units; a steel cable 13 is wound in the connecting component 7, and the steel cable 13 can extend out of the connecting component 7 to cooperate with the limiting component 4.

[0023] The limiting component 4 includes an abutting component 5 and a limiting piece 6. The limiting piece 6 is a steel plate with a pin, and the abutting component 5 is fixedly installed at the front end of the telescopic rod 3. A surrounding cable winding groove 18 is provided on the upper part of the abutting component 5 for cooperating with the steel cable 13 of the connecting component 7; a groove 19 is provided at the top end of the abutting component 5, which can fit on the first mounting bracket 1 in the case of non-use; a through hole is also provided in the middle of the abutting component 5, and the pin of the limiting piece 6 is inserted into the through hole to form a rotatable connection with the abutting component 5.

[0024] The described connecting component 7 includes a mounting shell 8, a retracting rod 9, a rotating motor 10, two transmission wheels 11, a transmission belt 12, a steel cable 13, a hook 14, a buffer 15, and a mounting plate 17; the rear end of the mounting shell 8 is movably connected to the sliding rod 2 through two perforated lugs passing through the sliding rod 2. The mounting shell 8 is of a cavity structure. The retracting rod 9 is installed inside the mounting shell 8. One end of the steel cable 13 is wound around the retracting rod 9, and the other end is provided with a hook 14; the rotating motor 10 is fixedly installed on the inner upper wall surface of the mounting shell 8 through the mounting plate 17; the two transmission wheels 11 are respectively fixedly installed on the retracting rod 9 and the output shaft of the rotating motor 10; the transmission belt 12 is sleeved on the two transmission wheels 11. The front lower edge of the mounting shell 8 is provided with a mounting groove 20 communicating with the inside of its shell, and the outer side edge of the mounting groove 20 is of a chamfered structure. The buffer 15 is movably installed in the mounting groove 20, and the outer end of the steel cable 13 passes through the buffer 15 and is connected to the hook 14. Two symmetric connecting hanging rings 16 are provided on the outer side surface of the buffer 15. In the non-use state, the hook 14 can be hung on one of the connecting hanging rings 16. In the use state, after dragging the hook 14 around the limiting component 4, it is then hung on the other connecting hanging ring.

[0025] In addition, the sliding rod 2 and the first mounting bracket 1 and the second mounting bracket 1-1, and the telescopic rod 3 and the second mounting bracket 1-1 are all in interference fit, so that the sliding rod 2 and the telescopic rod 3 can rotate or slide only when subjected to external forces, that is, when manually operated, so as to enable the user to adjust the positions of the sliding rod 2 and the telescopic rod 3, so that the connecting component 7 and the limiting component 4 are matched with the container.

[0026] A sponge pad (not shown in the drawings) can also be provided on the contact surfaces of the abutting member 5, the limiting member 6 and the container to reduce the wear caused by the collision between the abutting member 5 and the container and between the limiting member 6 and the container.

[0027] Based on the above solution, the usage method of the fixing device for the high-speed rail logistics container is as follows. First, adjust the distance between the two telescopic rods 3, and the size of the distance depends on the size of the container to be fixed. Then, move the container between the two telescopic rods 3 so that the two limiting components 4 are in contact with the opposite side surfaces of the container. Then, adjust the connecting component 7 on the sliding rod 2 so that it is in contact with the top of the container. Then, extend the steel cable 13 out of the connecting component 7 and pull the buffer member 15 so that the steel cable 13 cooperates with the two limiting components 4. At this time, the two limiting components 4 clamp and fix the side surface of the container, and the connecting component 7 fixes the top of the container. The steel cable 13 extends into the cable winding grooves 18 on the contact members 5 at the front ends of the left and right telescopic rods 3 in sequence and cooperates with the contact members 5. Then, the front hook 14 of the steel cable 13 is fixed on the connecting hanging ring 16 on the right side of the buffer member 15. Start the motor 10 to contract the steel cable 13 so that the connecting component 7 cooperates with the two limiting components 4 to prevent shaking during the high-speed rail driving, which may cause the separation of the limiting components 4, the connecting component 7 and the container. Generally speaking, by setting the steel cable 13, the connecting component 7 and the limiting component 4 are connected, and the container can be fixed. Generally, one container is placed in one set of fixing units. When two or more containers of the same model are stacked and the height is not higher than the height between the bottom of the high-speed multiple unit carriage and the bottom edge of the installation shell 8, they can be stacked and fixed with one set of fixing units. Compared with the prior art, by loosening or tightening the steel cable 13 on one side and moving and adjusting the sliding rod 2 and the telescopic rod 3, multiple containers can be fixed more reasonably, avoiding the problems that the overall device occupies too much land and it is difficult to fix or disassemble the container. The device is simple to operate and convenient to use, and is suitable for large-scale popularization and application.

[0028] It should be noted that although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirits of the present invention. The scope of the present invention is limited by the appended claims and their equivalents.
