Description

Technical Field

[0001] This invention relates to the field of grain hopper car top cover technology, specifically a translational grain hopper car top cover. Background Technology

[0002] Grain hopper cars are specifically designed for transporting bulk grain. The top of the car body has a loading opening, and the lower part is funnel-shaped, matching the loading and unloading facilities. During loading, grain is fed into the car body through the loading opening via a discharge chute. During unloading, the grain flows out automatically under its own weight. Compared to traditional boxcars and open wagons, grain hopper cars can effectively shorten loading and unloading time, accelerate vehicle turnaround, improve working conditions, and reduce transportation costs.

[0003] The existing grain hopper car's roof weight is distributed in sections, with each section heavy enough for one person to operate independently. However, the auxiliary time required to complete a single loading operation with all sections is relatively long, thus affecting transportation efficiency. Furthermore, the operator needs to open and close the roof structure from the roof; improper operation could result in personal injury. Summary of the Invention

[0004] The purpose of this invention is to provide a translational grain hopper truck top cover, which solves the problem of time-consuming and labor-intensive operation of traditional top covers. It is used in conjunction with the loading port of the truck body, and its drive shaft is located inside the truck body, allowing the cover to rotate under the drive shaft. The cover is equipped with vertical, longitudinal, and lateral positioning devices to ensure that the top cover is safe and reliable when closed. Cylinders are provided at both ends of the top cover, allowing it to be pneumatically opened.

[0005] The objective of this invention is achieved through the following technical solution:

[0006] A translational grain hopper truck cover includes a cover body located at the loading port of the truck body. One side of the cover body is hinged to a crank, which is connected to a drive shaft rotating inside the truck body. The other side of the cover body is hinged to a connecting lever, which is hinged to the truck body. The drive shaft is connected to a drive mechanism. The drive mechanism provides power to rotate the drive shaft, thereby rotating the crank and the connecting lever, realizing the translational movement of the four-bar linkage and enabling the cover body to slide open and close at the loading port.

[0007] Furthermore, the cover body includes a cover plate and a cover beam, which are welded together to form a cover body.

[0008] Furthermore, the cover is provided with a support, which is hinged to the crank and provides a transitional connection.

[0009] Furthermore, the drive shaft comprises several segments, with adjacent segments connected by couplings.

[0010] Furthermore, the drive shaft includes a hollow section and a solid section.

[0011] Furthermore, the middle part of the drive shaft is located on the bearing housing inside the vehicle body, and both ends of the drive shaft are located on the end bearing housing outside the vehicle body, so that the drive shaft can be rotated and supported for installation through the bearing housing.

[0012] Furthermore, a lateral limiting component is provided at the loading port of the vehicle body to laterally limit and lock the cover when it is closed.

[0013] Furthermore, the lateral limiting member is a lateral locking seat, which has a locking groove that cooperates with the locking rod on the cover.

[0014] Furthermore, the loading port of the vehicle body is provided with a longitudinal limiting component, which limits and locks the cover in the longitudinal direction when closed.

[0015] Furthermore, the longitudinal limiting member is a longitudinal stop.

[0016] Furthermore, the vehicle body is equipped with a lever stop, which is located at the open position of the connecting lever and supports and limits the connecting lever in the closed state.

[0017] Furthermore, the drive shaft is connected to the rocker arm, the rocker arm is hinged to the telescopic component, and the telescopic component is hinged to the vehicle body. The rocker arm swings and rotates through the hinged telescopic component, which synchronously drives the drive shaft to rotate.

[0018] Furthermore, the telescopic component is a self-locking cylinder.

[0019] The beneficial effects of this invention are:

[0020] 1. To provide an easy-to-operate top cover to effectively solve the problems of low work efficiency and poor operation safety in the existing technology.

[0021] 2. When the top cover is closed, the self-locking cylinder ensures its vertical locking capability, the longitudinal stop ensures its longitudinal locking capability, and the locking seat and locking rod ensure its lateral locking capability.

[0022] 3. A four-bar linkage mechanism is formed between the vehicle body, crank, connecting lever, and cover to achieve translational opening and closing of the cover, reducing space occupation.

Those skilled in the art, after understanding the solution of the present invention, will realize from the prior art and common general knowledge that there are many combinations, all of which are technical solutions to be protected by the present invention, and will not be exhaustively listed here.

[0032] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0033] refer to Figures 1 to 7 As shown, a translational grain hopper car top cover includes a cover body 1, a drive shaft 2, a bearing support 3, a bearing seat 4, an end bearing seat 5, a longitudinal stop 6, a transverse locking seat 7, a lever stop 8, a self-locking cylinder 9, a connecting lever 11, a crank 12, and a rocker arm 13.

[0034] The cover 1 is located at the loading port of the vehicle body. Opening or closing the cover at the loading port allows for loading or closing. The cover 1 is welded together from a cover plate and a cover beam. A support is provided on the cover 1, which is hinged to the crank 12. The cover adopts a pressed structure to reduce the free area of ​​the cover and increase its rigidity.

[0035] One side of the cover 1 is hinged to the crank 12 (seven on the vehicle body and two outside the vehicle), and the crank 12 is connected to the drive shaft 2 that rotates inside the vehicle body. The other side of the cover 1 is hinged to the connecting lever 11, and the connecting lever 11 is hinged to the vehicle body. Thus, a four-bar linkage is formed between the vehicle body, the crank, the connecting lever and the cover, which can realize the translation of the upper cover 1. At the same time, with the drive shaft 2 built-in, the overall installation space is reduced and the applicability is improved.

[0036] The driveshaft 2 comprises several segments, with adjacent segments connected by couplings to form the driveshaft installation along the longitudinal span of the entire vehicle body. The driveshaft 2 includes hollow and solid sections, which not only maintains structural strength but also saves materials.

[0037] The middle part of the drive shaft 2 is mounted on the bearing housing 4 inside the vehicle body, and both ends of the drive shaft 2 are mounted on the end bearing housings 5 ​​outside the vehicle body. The drive shaft 2 can be rotated and installed through the bearing housing 4 and the end bearing housings 5. Both the bearing housings and the crankshaft adopt a split structure, which facilitates the disassembly and maintenance of the drive shaft.

[0038] The bearing housing uses a split bearing with an internal nylon bushing for wear resistance and lubrication. The end bearing housing consists of a bearing cover, a rubber gasket, and a deep groove ball bearing with a sealing ring. The labyrinth structure, sealing ring, and gasket provide rain and dust protection to the end.

[0039] The bearing housing 4 is installed on the bearing support 3, which is fixed to the side wall beam. The support has an elongated hole and is directly connected to the bearing housing by bolts. It is also equipped with an adjusting shim to achieve longitudinal and vertical adjustment.

[0040] The loading port of the vehicle is equipped with lateral and longitudinal limiting components. The longitudinal, lateral, and vertical locking functions are achieved through longitudinal stops, lateral locking seats, and self-locking cylinders.

[0041] The lateral limiting component is a lateral locking seat 7, which has a locking groove that cooperates with the locking rod on the cover 1 to ensure its lateral locking capability when the top cover is closed. The longitudinal limiting component is a longitudinal stop 6, which ensures its longitudinal locking capability when the top cover is closed.

[0042] The vehicle body is equipped with a lever stop 8, which is located at the open position of the connecting lever 11. The lever stop is used to limit the connecting lever. When the cover is open, the connecting lever is placed on the lever stop to limit the four-bar linkage.

[0043] The drive shaft 2 is connected to the drive mechanism, which includes a rocker arm 13 and a telescopic component. The drive shaft 2 is connected to the rocker arm 13, the rocker arm 13 is hinged to the telescopic component, and the telescopic component is hinged to the vehicle body. The telescopic component is a self-locking cylinder 9. The self-locking cylinder provides driving force to rotate the rocker arm, thereby rotating the drive shaft. The self-locking cylinder ensures its vertical locking capability when the top cover is closed.

[0044] The foregoing basic examples and their further alternative examples of the present invention can be freely combined to form multiple embodiments, all of which are embodiments that can be adopted and claimed by the present invention. In the present invention, each alternative example can be arbitrarily combined with any other basic example and alternative example.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
