Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of railway loading and unloading vehicles, in particular to a car body pressing beam and a car dumper with a function of preventing derailment of the car body. Background Art
[0002] A car dumper is a key material handling device, mainly used for unloading coal and other bulk goods. The traditional manual unloading method is inefficient and labor-intensive, while the car dumper greatly improves the unloading efficiency through mechanized means. The car dumper clamps the car body 1 and rotates to pour coal into the unloading port, and then conducts subsequent processing through a conveyor belt or other transportation equipment. It is widely used in ports, power plants, steel mills and other fields, greatly improving the loading and unloading efficiency of bulk goods, reducing labor costs, and enhancing safety and automation levels. With the development of technology, the design of the car dumper has also been continuously optimized to adapt to different types and specifications of train car bodies 1.
[0003] There are many models of car dumpers. As one of the car dumpers, the "double-line double-tipping 'C'-type car dumper system (CD1 / CD2)" can unload car models including C80B, C63, C70, C70E, and C64, and the annual car unloading volume can reach 18 million tons. When this car dumper operates, each heavy train uses 4 sets of hydraulic car clamping devices to press the car body 1, and 2 hydraulic car side plates 4 tightly support the car body 1 on the side. A car body pressing beam 3 is installed on the upper part of the car clamping device. During the tipping operation of the car dumper, the car side plate 4 tightly supports the car body 1, and the car clamping device presses down to drive the car body pressing beam 3 to tightly press on the car body side 2, ensuring that the car body 1 does not derail when rotating and tipping with the car dumper.
[0004] In the prior art, as Figure 1 shown, the car body pressing beam 3 is driven by a car body pressing beam driving oil cylinder 6, and the car side plate 4 is driven by a car side plate hydraulic cylinder 5. The opening and closing of the action valve group of the car side plate hydraulic cylinder 5 are controlled by a control system relay. During the tipping operation, when the relay fails, the car side plate hydraulic cylinder 5 may lose pressure, resulting in the sudden retraction of the car side plate 4, causing the displacement of the car body 1, the separation of the car body side 2 from the car body pressing beam 3, and further resulting in the derailment accident of the car body 1 due to the loss of the tight support of the car body pressing beam 3. Summary of the Utility Model
[0005] The purpose of the utility model is to overcome the above-mentioned defects of the prior art, so as to provide a car body pressing beam and a car dumper with a function of preventing derailment of the car body.

[0025] The technical solution provided by the utility model is further explained below in conjunction with embodiments.
[0026] In order to ensure the safety of the train carriage 1 during the unloading operation of the tipping machine, the hydraulic cylinder 5 of the car plate is prevented from losing pressure, causing the car plate 4 to be retracted, the car 1 to shift, and the car side 2 to separate from the pressing beam 3, thereby causing the car 1 to lose the pressing support of the pressing beam 3, and finally causing the derailment of the car 1. The applicant has found that it is necessary to improve and optimize the structure of the pressing beam 3, so that even if a failure occurs and causes the car plate 4 to be retracted and the car 1 to shift, the car side 2 cannot separate from the pressing beam 3, ensuring the pressing support of the pressing beam 3 on the car 1, and preventing the derailment of the car 1.
[0027] like Figure 1As shown, the existing vehicle pressing beam 3 includes a vehicle pressing beam linkage part 31 arranged in the x direction. The vehicle pressing beam linkage part 31 is used to connect with the vehicle pressing beam driving oil cylinder 6. The vehicle pressing beam 3 further includes a vehicle pressing beam pressing part 32 arranged in the y direction. When the carriage side 2 is not undergoing a tipping operation, it is static in the y direction. The vehicle pressing beam linkage part 31 is fixedly connected to the vehicle pressing beam pressing part 32. The vehicle pressing beam linkage part 31 is driven by the vehicle pressing beam driving oil cylinder 6, driving the vehicle pressing beam pressing part 32 to move above the carriage side 2 and press against the carriage side 2.
[0028] As Figure 2 shown, in this embodiment, a set of stop devices 7 is added to the original structure of the vehicle pressing beam 3, and the width is ensured so that the carriage side 2 still cannot break away from the vehicle pressing beam 3 when the carboard 4 is fully retracted.
[0029] As Figure 3 shown, the stop device 7 includes: a stop device extension part 71, and the stop device extension part 71 is fixedly connected to the lower end of the vehicle pressing beam pressing part 32. The projected width of the stop device extension part 71 in the x direction after being connected to the vehicle pressing beam pressing part 32 is greater than the travel length of the carboard 4 in the x direction.
[0030] In one case, as Figure 3 shown, the stop device extension part 71 is fixedly connected to the bottom of the lower end of the vehicle pressing beam pressing part 32. In another case, as Figure 2 shown, the stop device extension part 71 is fixedly connected to the side wall of the lower end of the vehicle pressing beam pressing part 32.
[0031] To increase the strength of the stop device 7, the stop device 7 further includes a stop device reinforcement part 72. As Figures 2 to 3 shown, the stop device reinforcement part 72 is connected to the side wall of the vehicle pressing beam pressing part 32 and the top of the stop device extension part 71, jointly forming a triangular structure.
[0032] The stop device extension part 71 uses the stop device reinforcement part 72 as a stiffening rib plate.
[0033] The stop device extension part 71 is welded to the vehicle pressing beam pressing part 32.
[0034] The stop device reinforcement part 72 is welded to the side wall of the vehicle pressing beam pressing part 32 and the top of the stop device extension part 71.
[0035] Figure 2 Only one stop device 7 is shown, but it should be noted that several stop devices 7 can be installed on the vehicle pressing beam 3, such as 2, 3, 4, etc., to increase stability. Several stop devices 7 can be arranged from the head to the tail of the carriage, that is Figure 2The direction is into the paper surface, arranged uniformly or non-uniformly. As a preferred embodiment, a stop device 7 can be arranged at the corresponding position of the head of the carriage, and a stop device 7 can be arranged at the corresponding position of the tail of the carriage. All in all, the number of the stop devices 7 can ensure that its total strength can support the fully loaded carriage 1.
[0036] The stop device 7 is made of Q345 steel and is 25 mm thick. Two reinforcing rib plates of the same material and thickness are arranged on the stop device 7 and are integrally welded on the original pressing beam 3 steel structure to ensure that the strength of the 2 groups of stop devices 7 can support a fully loaded carriage 1.
[0037] In the existing pressing beam 3, when the car board 4 is completely retracted due to a failure, the pressing beam 3 moves with the car board 4, resulting in the separation of the original pressing beam 3 structure from the car body side 2 of the carriage.
[0038] However, for the pressing beam 3 provided in this embodiment, since the width of the added stop device 7 is greater than the full retraction stroke of the car board 4, it can ensure that the car body side 2 of the train carriage will not separate from the stop device 7, ensuring that the pressing beam 3 always provides a pressing and supporting effect for the carriage 1 and ensuring that the carriage 1 will not derail due to equipment failure during the flipping process with the car dumper.
[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the embodiments, those of ordinary skill in the art should understand that any modification or equivalent replacement of the technical solutions of the present invention does not depart from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
