Description

Technical Field

[0001] This utility model relates to the field of wide-gauge vehicle technology, and in particular to a bottom-opening wide-gauge vehicle box adapted for loading cargo boxes. Background Technology

[0002] Bottom-opening wide-gauge wagons are vehicles with an openable funnel-shaped door at the bottom, enabling rapid unloading via pneumatic, manual, or tipper control. During unloading, materials are discharged from the bottom of the wagon by gravity, significantly increasing efficiency compared to traditional manual or mechanical loading and unloading methods.

[0003] Our existing bottom-opening wide-gauge wagons have a load capacity of 70 tons. Due to business needs, we need to use these wagons to transport containers. Each wagon can only carry a maximum of two containers, and because the sum of the lengths of the two containers is less than the length of the wagon itself, the containers tend to sway inside the wagon. To address this, we have developed a limiting unit fixedly installed inside the wagon. This unit uses multiple sets of limiting blocks arranged at the four corners and with guide ramps at the top to form a limiting cavity that limits the movement of a single container. However, this limiting unit has the following problems in practical application:

[0004] 1. When using a crane to lift the container into the truck bed, the container is prone to high-intensity hard contact collision with the limiting block during the descent, which can cause deformation and damage to the edge of the container and the upper part of the limiting block.

[0005] Second: The container is guided into the limiting cavity by sliding contact between the guide ramp at the upper end of the limiting block and the bottom of the container, which can easily cause severe wear on the bottom of the container and the upper end of the limiting block.

[0006] Therefore, this application provides a bottom-opening wide-rail car body adapted to load cargo boxes to meet the requirements. Utility Model Content

[0007] The purpose of this application is to provide a bottom-opening wide-gauge wagon that is adapted to load cargo boxes, in order to solve the technical problems mentioned in the background above.

[0008] To achieve the above objectives, this application provides the following technical solution: a bottom-opening wide-rail car body adapted to load cargo boxes, including a car body loaded with containers, wherein limiting units are provided at the four corners of the car body and at the four corners of the opposite ends of the two sets of containers, and the limiting unit includes a sliding rail vertically installed on the inner wall of the car body and two sets of contact rollers installed on the mounting plate;

[0009] The mounting plate is slidably mounted on the sliding rail via a slider;

[0010] The two sets of contact rollers are mounted on the mounting plate by L-shaped rods, and the two sets of contact rollers are arranged vertically, and the outer surface of the contact rollers is covered with an elastic buffer layer made of rubber material;

[0011] There is a gap between the lower end of the sliding track and the bottom of the inner cavity of the carriage;

[0012] A positioning unit is also provided for suspending and positioning the mounting plate on the sliding track.

[0013] In a preferred embodiment of this invention, the positioning unit includes a positioning rod slidably disposed on the mounting plate; a first ejector block movably disposed in the inner cavity of the movable hole on the sliding track by a first ejector spring; and a second ejector block movably disposed in the inner cavity of the movable hole below the sliding track by a second ejector spring.

[0014] A positioning spring is fitted on the positioning rod, and the two ends of the positioning spring are fixedly connected to the positioning rod and the mounting plate respectively. A pull rope is fixed to the right end of the positioning rod, and the right end of the pull rope is assembled on the guide wheel and finally connected to the boom handle. The guide wheel is mounted on the mounting plate.

[0015] The lower end of the slider is fixed with a magnetic shielding block, and the inner cavity of the magnetic shielding block is provided with a permanent magnet.

[0016] The elastic coefficient of the positioning spring is greater than that of the first ejection spring;

[0017] Initially, the first ejector block and the second ejector block are located in the inner cavities of the upper movable hole and the lower movable hole, respectively.

[0018] In a preferred embodiment of this invention, the spiral handle is slidably mounted on the mounting plate, and a blocking ring is installed on the spiral handle.

[0019] In a preferred embodiment of this invention, an elastic buffer pad is fixed to the right end of the second ejector block.

[0020] In a preferred embodiment of this invention, the longitudinal length of the permanent magnet is not less than twice the longitudinal length of the second ejector block.

[0021] In summary, the technical effects and advantages of this utility model are as follows:

[0022] 1. The present invention has a reasonable structure. The elastic buffer layer of the contact roller transforms the rigid collision of the traditional limiting block into elastic buffer, effectively reducing the damage to the container. Moreover, the rolling contact of the contact roller has a good collision unloading effect and also reduces friction and wear. Compared with the limiting block, the use of contact roller can greatly improve the service life of this limiting structure and the container.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] Example: Reference Figure 1-5 The bottom-opening wide-rail carriage adapted to load cargo boxes includes a carriage 1 loaded with containers 2. Limiting units 3 are provided at the four corners of the carriage 1 and at the four corners of the opposite ends of the two sets of containers 2. The limiting unit 3 includes a sliding rail 5 vertically installed on the inner wall of the carriage 1 and two sets of contact rollers 8 installed on the mounting plate 4.

[0033] Mounting plate 4 is slidably mounted on sliding rail 5 via slider 6;

[0034] Two sets of contact rollers 8 are mounted on the mounting plate 4 via L-shaped rods 7, and the two sets of contact rollers 8 are arranged vertically, and the outer surface of the contact rollers 8 is covered with an elastic buffer layer made of rubber material;

[0035] A gap is provided between the lower end of the sliding track 5 and the bottom of the inner cavity of the carriage 1;

[0036] It is also equipped with a positioning unit to suspend and position the mounting plate 4 on the sliding rail 5.

[0037] Two sets of vertically arranged contact rollers 8 (rotatably connected to L-shaped rods 7) respectively contact and limit the two sides of the container 2 in the transverse and longitudinal directions. The elastic buffer layer on the outer surface of the contact rollers 18 can form a soft collision with the container 2, that is, transform the rigid collision of the traditional limit block into an elastic buffer, reducing the collision damage to the bottom of the container 2. At the same time, the contact rollers 18 and the container 2 are in rolling contact, which has a good collision unloading effect and also greatly reduces the friction between them and the container 2, avoiding serious wear on the container 2. Compared with the limit block, the use of contact rollers 8 can greatly improve the service life of this limit structure and the container.

[0038] It should be noted that: First, the mounting plate 4 can be directly removed from the sliding rail 5. After removal, the carriage 1 can also be used to load ore (such as coal). Second, there is a gap between the lower end of the sliding rail 5 and the bottom of the inner cavity of the carriage 1. When loading ore into the carriage 1, ore particles will accumulate in the groove on the sliding rail 5. After the slider 6 is inserted and installed into the sliding rail 5, the slider 6 moves vertically downward. The gravity of the limiting unit 3 (except for the sliding guide rail 5) can squeeze the ore particles in the groove and drive them downward, and finally make the ore particles discharge from the bottom of the sliding rail 5. The gap provides space for the discharge of ore particles accumulated in the groove.

[0039] As a preferred embodiment of this example, Figure 2-5 As shown, the positioning unit includes a positioning rod 12 slidably disposed on the mounting plate 4; a first ejector block 14 movably disposed in the inner cavity of the movable hole on the sliding track 5 by a first ejector spring 15; and a second ejector block 16 movably disposed in the inner cavity of the movable hole below the sliding track 5 by a second ejector spring 17.

[0040] A positioning spring 13 is fitted on the positioning rod 12, and the two ends of the positioning spring 13 are fixedly connected to the positioning rod 12 and the mounting plate 4 respectively. A pull rope 10 is fixed to the right end of the positioning rod 12, and the right end of the pull rope 10 is assembled on the guide wheel 11 and finally connected to the loop handle 9. The guide wheel 11 is installed on the mounting plate 4.

[0041] A magnetic shielding block 18 is fixed at the lower end of the slider 6, and a permanent magnet 19 is provided in the inner cavity of the magnetic shielding block 18.

[0042] The elastic coefficient of the positioning spring 13 is greater than that of the first ejection spring 15;

[0043] Initially, the first ejector block 14 and the second ejector block 16 are located in the inner cavities of the upper movable hole and the lower movable hole, respectively.

[0044] Installation of mounting plate 4 and sliding rail 5: The installer can directly lift the U-shaped handle 9 by hand. At this time, the U-shaped handle 9 will drive the positioning rod 12 to compress the positioning spring 13 through the pull rope 10, installing the slider 6 onto the sliding rail 5 and causing the mounting plate 4 to move slowly downward along the sliding rail 5. When the permanent magnet 19 moves to the lower movable hole, the magnetic force of the permanent magnet 19 will cause the second ejector block 16 to move outward and finally move out of the lower movable hole. As the mounting plate 4 continues to move downward, the lower end of the slider 6 will... When the upper end of the second ejector block 16 extends outward and contacts the mounting plate 4, the downward movement is blocked. At this time, the hand holding the loop handle 9 can be released. Through the elastic force of the positioning spring 13, the positioning rod 12 moves outward and contacts the first ejector block 14 to form a compression. Finally, the left end of the positioning rod 12 moves into the upper movable hole (at this time, the first ejector spring 15 is compressed), which longitudinally limits the mounting plate 4. The installation of the slider 6 and the sliding rail 5 forms a lateral limit for the mounting plate 4, and finally the mounting plate 4 is suspended in the air and installed on the sliding rail 6.

[0045] During disassembly, you can directly grasp the loop handle 9 and lift it up. During this process, the pull rope 10 will exert a pulling force on the positioning rod 12, causing the positioning rod 12 to move out of the upper movable hole, the longitudinal limit is released, and the mounting plate 4 will be pulled upward by the force.

[0046] After the positioning rod 12 moves out of the upper movable hole, the first ejector block 14 returns to its original position by the elastic force of the first ejector spring 15, that is, the outer end of the first ejector block 14 is flush with the surface of the sliding track 5; when the permanent magnet 19 moves to the upper part of the lower movable hole, the second ejector block 15 returns to its original position by the elastic force of the second ejector spring 17, that is, the outer end of the second ejector block 16 is flush with the surface of the sliding track 5.

[0047] Since the ore material is loaded into the car body 1 and the ore material is unloaded, the ore particles that have entered the upper and lower movable holes can be pushed out by the elastic force of the first ejection spring 15 and the second ejection spring 16.

[0048] This limit unit is easy and quick to disassemble and install.

[0049] As a preferred embodiment of this example, Figure 3 As shown, the spiral handle 9 is slidably mounted on the mounting plate 4, and a blocking ring 20 is installed on the spiral handle 9.

[0050] The setting of its blocking ring 20 ensures that there is always a certain space for fingers to be inserted between the handle of the spiral handle 9 and the upper end of the mounting plate 4, making it convenient for people to hold the handle.

[0051] As a preferred embodiment of this example, Figure 5As shown, an elastic buffer pad is fixed to the right end of the second ejector block 16.

[0052] The collision between the end of the second ejector block 16 and the permanent magnet 19 can be reduced by the elastic buffer pad.

[0053] As a preferred embodiment of this example, Figure 5 As shown, the longitudinal length of the permanent magnet 19 is not less than twice the longitudinal length of the second ejector block 16.

[0054] This ensures that during installation, even when the mounting plate 4 moves downward at a relatively fast speed, the second ejector block 16 can extend out of the lower movable hole in advance under the action of magnetic force and eventually contact the lower end of the slider 6 to form a block.

[0055] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
