Description

Technical Field

[0001] This utility model belongs to the field of freight car technology and relates to a compartment layering device for a freight car. Background Technology

[0002] Using trucks to transport goods is one of the mainstream methods for long / short-distance freight transport. As the name suggests, it involves packing and loading the goods to be transported in the cargo compartment of a truck and then transporting them.

[0003] When there are at least two nearby destinations and the truck can hold enough goods, in order to effectively control costs, a sufficient amount of goods are usually stacked in the truck and delivered to the two destinations in batches. However, with continuous operational practice, it has been found that truck transportation has many inconveniences. First, due to the large number of goods stacked, the goods at the bottom are very likely to be damaged. Second, when unloading goods, because the goods are stacked together, the unloading personnel cannot distinguish them correctly, which often leads to unloading errors, overloading, and omissions. Summary of the Invention

[0004] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing a compartment layering device. The technical problem to be solved by this utility model is: how to effectively classify and stack goods while preventing them from being crushed.

[0005] The objective of this utility model can be achieved through the following technical solution: a compartment layering device, wherein the compartment is provided with a horizontal bar that divides the interior cavity of the compartment vertically, the layering device includes a rectangular plate-shaped support plate, characterized in that a locking plate with a locking hole on the plate surface is fixedly provided on the top of the compartment, one end of the support plate is hinged to the inner side wall of the compartment, and the other end has a receiving cavity, wherein a pin and a spring are provided in the receiving cavity, and a pull rod is provided along the length direction of the support plate, passing through the receiving cavity and connected to the pin, the spring is sleeved on the pull rod, and the spring elastically acts on the pin, causing the pin to extend out of the end of the support plate and insert into the locking hole.

[0006] The operating principle of the compartment's tiered system is as follows: Before operation, crossbars are installed inside the compartment to initially divide it into upper and lower sections, thus achieving preliminary planning of the interior space. The crossbars also serve as a support structure to support the support plate, ensuring its stability when horizontally positioned. In its retracted state, the support plate is generally vertically positioned within the compartment. At this time, a pin extends from the support plate under the elastic action of a spring and enters the locking hole. Since one end of the support plate is hinged to the inner wall of the compartment, it can only rotate around the hinge point. Furthermore, the locking hole wall limits the pin, causing the other end of the support plate to be positioned by the locking plate. This state ensures the support plate remains vertical. During use, the worker can... Pulling the lever downwards causes the lever to move the pin towards the hinge end of the support plate. At this point, the pin overcomes the elastic force and disengages from the locking hole, allowing the end of the support plate locked by the locking plate to move freely. In this state, the worker can manipulate the support plate to swing it downwards around the hinge and eventually make one side of the plate abut against the crossbar. The crossbar and the support plate work together to create upper and lower layers in the interior cavity of the carriage. When loading goods, they can be stacked in an orderly manner on the upper or lower layer of the carriage as needed, effectively avoiding the problems of inconvenience in unloading and damage to the goods. It is worth mentioning that the assembly of the pin, spring, and lever is achieved through the existing cavity inside the support plate, eliminating the need for additional components to accommodate them on the support plate, ensuring a simpler structure and lower manufacturing costs.

[0007] In the aforementioned compartment layering device, the support plate has an installation opening that penetrates the bottom wall of the receiving cavity. A guide sleeve, closed at one end, is provided along the length of the support plate. The guide sleeve is fitted into the installation opening and fixedly connected to its inner wall. One end of the spring abuts against the closed end of the guide sleeve, and the other end abuts against the head of the pin. This positioning of the spring's two ends ensures sufficient elastic force acting on the pin head. Furthermore, it allows the separate guide sleeve and support plate to ensure that the spring and pin can be properly installed into the receiving cavity during production assembly.

[0008] In the aforementioned compartment tiering device, the closed end of the guide sleeve has a through hole communicating with the receiving cavity. The pull rod extends into the receiving cavity through the through hole. The inner wall of the closed end of the guide sleeve has an annular edge with an inner diameter the same as the inner diameter of the through hole. The annular edge surrounds the through hole, and the outer peripheral wall of the pull rod fits against the through hole and the inner peripheral wall of the annular edge. The through hole ensures that the pull rod can extend into the receiving cavity and connect with the pin, and the guide effect of the through hole and the inner wall of the annular edge prevents the pull rod from shifting laterally.

[0009] In the aforementioned compartment layering device, the support plate has a clearance hole at one end of the receiving cavity. The clearance hole penetrates the top wall of the receiving cavity, and the pin passes through the clearance hole. The clearance hole allows the pin to extend out of the support plate end face and into the locking hole, and the wall of the locking hole also provides a guiding effect for the pin.

[0010] In the aforementioned compartment layering device, the locking plate is rectangular, with both ends bent to form bends. The locking hole is located in the middle of the locking plate, and a gap is formed between the middle of the locking plate and the inner wall of the compartment top. This allows the pin, after being inserted into the locking hole, to be accommodated through the gap between the middle surface of the locking plate and the inner wall of the compartment top, ensuring the stability of the pin's positioning and thus guaranteeing that the support plate can be firmly locked in a vertically positioned state.

[0011] In the aforementioned compartment tiering device, fixing rods are fixed to the inner side walls on both sides of the compartment. Each fixing rod has a slot. One end of a crossbar engages with the slot of one of the fixing rods, and the other end engages with the slot of the other fixing rod. This allows the crossbars to be detachable, ensuring that the compartment can be selectively tiered or not tiered for different goods, thus increasing its versatility.

[0012] In the aforementioned compartment layering device, each of the fixed rods has an extension on its side wall extending toward the inner wall of the compartment top, and the support plate is hinged to the extension. This prevents the installation of the support plate from damaging the inner wall structure of the compartment.

[0013] In the aforementioned compartment layering device, the inner wall of the compartment has a chain, and the inner wall of the support plate near the hinge is provided with a hook. When the pin is inserted into the locking hole, the chain connects with the hook. When the support plate is in a vertical arrangement (i.e., in the retracted state), the chain and hook can be connected to achieve the advantage of double locking of the support plate, ensuring more stable positioning of the support plate.

[0014] Compared with existing technologies, the layering device of this carriage has the following advantages:

[0015] 1. The crossbar initially divides the interior cavity of the carriage into upper and lower sections. When the user pulls the lever, the lever overcomes the elastic force of the spring to drive the pin out of the locking hole, thereby releasing the locking plate from the support plate. This causes the support plate to flip around the hinge and abut against the crossbar, thus achieving the upper and lower division of the carriage.

[0016] 2. The internal cavity of the support plate accommodates the pins and springs, effectively reducing structural complexity and controlling costs.

[0017] 3. The support plate is hinged to the extension of the fixed rod. The support plate bears the weight of the support plate and the shearing force generated during operation, thus avoiding damage to the inner wall of the carriage. Attached Figure Description

[0025] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0026] like Figure 1 , Figure 2 as well as Figure 5 As shown, in the layered device of this carriage, long strip-shaped fixing rods 13 are welded and fixed in the middle of the inner walls on both sides of the carriage 1. Each fixing rod 13 has several slots 131 arranged at intervals along the length direction on its upper side. The slots 131 on the two fixing rods 13 are positioned opposite each other. Several crossbars 11 are arranged at intervals along the width direction inside the carriage 1. One end of each crossbar 11 is engaged in the slot 131 of one fixing rod 13, and the other end is engaged in the slot 131 of another fixing rod 13.

[0027] Combination Figure 3 , Figure 4 as well as Figure 6 Each fixing rod 13 has an extension 132 extending toward the top of the carriage 1 on one side of its outer wall. The layering device includes several support plates 2 spaced apart along the length of the carriage 1 on the inner walls of both sides. Each support plate 2 is rectangular, with one end being the upper end and the other end being the lower end. The lower end of the support plate 2 is hinged to the extension 132, and the upper end is provided with a clearance hole 21. Furthermore, there is a receiving cavity 22 inside the support plate 2 near the upper end, and the clearance hole 21 penetrates the top cavity wall of the receiving cavity 22. A pin 221 that passes through the clearance hole 21 is movably connected in the receiving cavity 22.

[0028] The support plate 2 has an installation port 26 that penetrates the bottom wall of the receiving cavity 22. A guide sleeve 24 with one closed end is fixed along the length of the fixing plate. The closed end of the guide sleeve 24 is engaged in the installation port 26 and fixedly connected to the inner circumferential wall of the installation port 26. The closed end of the guide sleeve 24 has a through hole 241 communicating with the receiving cavity 22. An annular edge 242 is integrally formed on the inner bottom wall of the closed end of the guide sleeve 24. The annular edge 242 surrounds the through hole 241 and its inner diameter is equal to the inner diameter of the through hole 241. Each guide sleeve... Each of the 24 is equipped with a pull rod 23. One end of the pull rod 23 extends into the open end of the guide sleeve 24 and into the receiving cavity 22 through the through hole 241 at the closed end of the guide sleeve 24, and is connected to the pin 221 (it can be directly welded or threaded). The other end of the pull rod 23 protrudes from the open end of the guide sleeve 24 and is fixedly connected to a pull ring. The receiving cavity 22 is also equipped with a spring 222. The spring 222 is sleeved on the outside of the pull rod 23, with one end pressing against the end of the pin 221 and the other end pressing against the outer wall of the closed end of the guide sleeve 24.

[0029] Several locking plates 12 are provided on both sides of the top of the carriage 1 near the edge. The locking plates 12 are positioned opposite to several support plates 2. Specifically, the locking plates 12 are strip-shaped with bent portions 122 at both ends. Locking holes 121 are opened in the middle of the locking plates 12. The locking plates 12 are welded to the inner wall of the top of the carriage 1 through at least one bent portion 122, so that a gap 3 is formed between the middle of the locking plates 12 and the inner wall of the top of the carriage 1. In addition, chains 14 are installed on the inner walls of both sides of the carriage 1 corresponding to several support plates 2. At the same time, hooks 25 are provided near the lower end of the support plates 2.

[0030] Operating principle: When it is necessary to divide the cavity inside the carriage 1 into upper and lower layers, the worker first clamps several crossbars 11 between two fixed rods 13 in the carriage 1. Then, the pull rings on each support plate 2 are pulled in sequence, causing the pull rod 23 to move downward. At this time, the pull rod 23 drives the pin 221 to disengage from the locking hole 121 of the locking plate 12, thereby unlocking the upper end of the support plate 2. Then, the lower end of the support plate 2 rotates around the hinge and one side of the plate abuts against the crossbar 11. The process is completed by covering the crossbar 11 with several support plates 2 in pairs. For the compartment 1, the layering is as follows; conversely, when the layering device needs to be disassembled, simply rotate each support plate 2 upwards in sequence, then pull the pull ring to make the pull rod 23 move the pin 221 downwards a certain distance. When the clearance hole 21 on the top of the support plate 2 and the locking hole 121 on the lock plate 12 are aligned, release the pull ring, so that the elastic element pushes the pin 221 out and into the locking hole 121. Then, it is connected to the hook 25 through the chain 14, so that each support plate 2 is kept in a vertical setting. Finally, each crossbar 11 can be removed from the compartment 1.
