Description

Technical Field

[0001] The utility model relates to an auxiliary tool for a compartment door of a bulk cargo train compartment. Background Art

[0002] Bulk cargo train wagons are often used to transport bulk cargo such as coal and ore. A discharge port is provided at the lower part of the side wall 1 of the carriage, and the discharge port is equipped with a carriage door 2. The carriage door 2 is fixed on two long slats 3. The tops of the two long slats 3 are hingedly fixed to the side wall 1 of the carriage, and the lower ends of the long slats 3 protrude from the carriage door 2. A rotatable card plate 4 is hinged on one side of the lower end of each long slat 3, and a card seat 5 is provided on the other side. A card slot 6 is provided on the card seat 5. The free end of the card plate 4 can rotate around its hinge axis and be stuck in the card slot 6. The middle part of the card plate 4 is pressed on the lower end of the long slat 3, thus forming a locking mechanism for the carriage door, thereby fixing the carriage door 2 on the discharge port. Figure 1 Shown on the left.

[0003] When loading, the cargo is loaded from the top of the bulk cargo train car. When unloading, the pallet is pulled away from the seat to release the long slats. The bulk cargo automatically pushes open the unloading door under the action of gravity, and most of it flows out of the car. The remaining bulk cargo inside the car is cleaned out manually.

[0004] During unloading and transportation, the lower part of the long slats is often deformed and warped due to collisions or other external forces, causing the card plate in the door lock mechanism to be unable to close. In this case, to lock the door, it is necessary to use external force to press the lower end of the warped long slats back so that the card plate can be normally inserted into the card slot and the door can be locked and fixed.

[0005] However, the prior art lacks effective tools. In such a situation, the only way is to use a hammer or other tools to hit the long slats to restore them to their original state, which is time-consuming and laborious. Summary of the invention

[0006] The technical problem to be solved by the utility model is how to fill the above-mentioned gap in the prior art and provide an auxiliary tool for a compartment door of a bulk cargo train compartment.

[0007] In order to solve the above technical problems, the auxiliary tool for the compartment door of a bulk cargo train carriage comprises a hook body and a lever, wherein the hook body is located below the lever, and the rear end of the hook body is hinged on the lever, the front end of the hook body passes over the front end of the lever and is bent upward to form a bent portion, and the front end of the lever is against the lower end of the long slat on the compartment door of the bulk cargo train carriage, and the bent portion of the hook body can be stuck on the beam on the outside of the bulk cargo train carriage, and the lever is lifted upward to press the lower end of the long slat toward the bulk cargo train carriage.

[0008] With such a design, when the lower end of the long slat on the compartment door is tilted and the card plate of the locking mechanism cannot be inserted into the card slot, the auxiliary tool for the compartment door of the bulk cargo train compartment is taken out, the front end of the lever is pressed against the lower end of the long slat on the compartment door of the bulk cargo train compartment, the bent part of the hook body can be clamped on the beam outside the bulk cargo train compartment, and then the lever is lifted upward to press the lower end of the long slat toward the bulk cargo train compartment. Figure 1 As shown in the right part, the deformed long strip is corrected.

[0009] Then the card plate can be rotated so that the middle part of the card plate is pressed on the lower end of the long strip, and the free end of the long strip is inserted into the card slot, so that the compartment door can be firmly locked.

[0010] As an optimization, a base block is provided at the front end of the lever, and the lever is pressed against the lower end of the long slat of the compartment door through the base block. With such a design, the contact area between the lever and the long slat is large, and the long slat is not easy to deform.

[0011] As an optimization, a transverse ridge is provided in the middle of the base block, and the outer surfaces of the base block above and below the transverse ridge are both planes, and the distance L1 between the inner surface of the base block below the transverse ridge and the axis of the hinge shaft at the rear end of the hook body is smaller than the distance L2 between the outer surface of the base block above the transverse ridge and the axis of the hinge shaft at the rear end of the hook body. With this design, before lifting the lever, the plane below the transverse ridge is used to press the long strip, and after lifting the lever, the plane above the transverse ridge is used to press the long strip, so the contact area is large and not easy to deform.

[0012] As an optimization, a tension spring is arranged between the hook body and the front part of the lever. With such a design, the hook body does not fall down without hand support during use, and the bent part of the hook body can be stuck on the beam outside the bulk cargo train carriage, which is very convenient.

[0013] As an optimization, the rear of the lever is also covered with an outer tube, and the lever can be extended and retracted in the outer tube to extend the lever force arm. With this design, the lever and the outer tube form a retractable lever. When it is necessary to save effort, the outer tube is pulled outward to extend the length of the lever force arm, thereby achieving a labor-saving effect.

[0014] As an optimization, the outer end of the hook body is provided with a cylindrical hook head or an inwardly bent hook head. With such a design, when in use, the cylindrical hook head or the inwardly bent hook head is used to hook the beam of the outer side of the bulk cargo train carriage, which is not easy to slip off.

[0015] The auxiliary tool for the compartment door of a bulk cargo train has a simple structure and is easy to use and is suitable for use on the compartment door of a bulk cargo train. BRIEF DESCRIPTION OF THE DRAWINGS
