[0001] This utility model relates to the field of wide-gauge vehicle technology, and in particular to a bottom-opening wide-gauge vehicle with a limiting structure. 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 wagon has a load capacity of 70 tons. Due to business needs, we need to use this wide-gauge wagon to transport containers. Each wagon can carry a maximum of two containers. Since the sum of the lengths of the two containers is less than the length of the wagon, the containers are prone to shaking inside the wagon. Therefore, this application provides a bottom-opening wide-gauge wagon with a limiting structure to meet the requirements. Utility Model Content
[0004] The purpose of this application is to provide a bottom-opening wide-gauge vehicle with a limiting structure to solve the technical problem of container shaking inside the vehicle when a wide-gauge vehicle is used to transport containers in the prior art.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Example: Reference Figure 1-3 The bottom-opening wide-gauge car with a limiting structure shown includes a frame 3 with a car body 1 at the upper end. The car body 1 is a low-opening type. A rocker arm 4 is installed at the lower end of the frame 3, and a wheel pair 2 is installed on the rocker arm 4. It also includes a limiting unit for limiting the container in the car body 1 to prevent the container 1 from shaking.
[0024] The limiting unit includes multiple sets of first limiting blocks 5 and multiple sets of second limiting blocks 7. The multiple sets of first limiting blocks 5 are arranged in an arc shape on the inner wall of the carriage 1.
[0025] Multiple sets of second limiting blocks 7 are located in the middle of the carriage 1, and are arranged opposite to each other in pairs;
[0026] Each of the multiple sets of first limiting blocks 5 and multiple sets of second limiting blocks 7 has a guide ramp on one end facing the corresponding container.
[0027] As a preferred embodiment of this invention, an adjustment unit is also provided for adjusting the distance between the two sets of second limiting blocks 7 that are arranged opposite to each other.
[0028] The container is limited on all four sides by the cooperation of multiple sets of second limiting blocks 7 and multiple sets of first limiting blocks 5, thereby preventing the container from shaking during transportation and improving the stability and safety of transportation. The guide slope set on it is conducive to lifting the container into the limiting cavity (which is the same size as the container) formed by multiple sets of second limiting blocks 7 and multiple sets of first limiting blocks 5.
[0029] As a preferred embodiment of this example, Figure 4 As shown, the adjustment unit includes a U-shaped plate 6 fixedly installed on the inner wall of the carriage 1, two sets of second limiting blocks 7 slidably installed in the arc-shaped cavity of the U-shaped plate 6, two sets of toothed plates 8 arranged vertically on the opposite ends of the two sets of second limiting blocks 7, a rotating shaft 10 rotatably installed between the two sets of toothed plates 8, and a gear 9 fixedly sleeved on the rotating shaft 10. The gear 9 meshes with the two sets of toothed plates 8 respectively. The end of the rotating shaft 10 near the carriage 1 passes through the carriage 1 and extends to its outside. An elastic damping pad is provided at the rotatable connection between the rotating shaft 10 and the U-shaped plate 6.
[0030] It is also equipped with a locking structure to prevent the two sets of second limit blocks 7, which are set opposite to each other, from moving relative to each other due to compression.
[0031] The two sets of second limiting blocks 7 can be moved away or together simultaneously by rotating the rotating shaft 10, thereby adjusting the distance between the two second limiting blocks 7. This allows the wide-gauge vehicle to adapt to the placement of containers of different lengths, enhancing the versatility and practicality of the equipment. At the same time, a locking structure is set to prevent the two sets of oppositely positioned second limiting blocks 7 from moving relative to each other due to compression, which is beneficial to the stability of the second limiting blocks 7.
[0032] As a preferred embodiment of this example, Figure 4 As shown, the locking structure includes a worm gear 12 rotatably disposed in the inner cavity of the spiral plate 6. The worm gear 12 is meshed with a worm wheel 11 disposed on the rotating shaft 10. A first bevel gear 13 is fixed to one end of the worm gear 12, and the first bevel gear 13 is meshed with a second bevel gear 14. The second bevel gear 14 is mounted on a rotating rod, and one end of the rotating rod near the inner wall of the carriage 1 passes through the carriage 1 and is connected to a hand crank 15.
[0033] The second bevel gear 14 can be driven by the hand crank 15 to rotate the first bevel gear 13. The rotation of the first bevel gear 13 can drive the worm gear 12 to rotate. The worm gear 12 and the worm wheel 11 work together to drive the rotating shaft 10 to rotate. Finally, the two sets of second limit blocks 7 move away or together at the same time. Since the worm gear 12 and the worm wheel 11 can self-lock, the container cannot squeeze the second limit blocks 7 to make the two sets of second limit blocks 7 move together, so that the second limit blocks 7 can stably limit the container.
[0034] 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.
