Technical Field

[0001] The invention belongs to the technical field of coal transport train accessories, and in particular relates to a door supporting device for a coal transport train. Background Art

[0002] Coal is used for coking, which can produce coal tar and ammonia. Coke is an important raw material for iron smelting. Coal tar can be used to extract a variety of important industrial compounds. Many people think that coal gas is made from coal, but the fact is that coal gas is refined from naphtha extracted from crude oil. Coal can also be directly vaporized to produce water gas (a mixture of carbon monoxide and hydrogen), which can be used directly as a clean fuel.

[0003] Transportation is an indispensable part of coal mining. In the prior art, coal trains are generally used to transport coal. Each carriage of the coal train is usually equipped with a coal train door, which includes a door body and two locking assemblies symmetrically installed on both sides of the door body; each locking assembly includes a hanging ring, an ear plate, two fixed blocks and a rotating pin; the upper part of the door body is connected to the body axis of the coal train, the ear plate is installed at the lower part of the door body, and the hanging ring is rotatably connected to the lower part of the door body. When the door body is in a closed state, two fixed blocks are fixed on the body of the coal train below the door body, and the two fixed blocks are arranged on both sides of the ear plate. The rotating pin is connected to the fixed block shaft on one side, and the rotating pin rotates toward the fixed block on the other side to limit the ear plate between the rotating pin and the body of the coal train. At this time, the coal train door is locked.

[0004] After unloading coal, the staff needs to clean the train carriage. It is very necessary to study a coal transport train door support device with a simple structure that can cooperate with a locking component to provide support during cleaning. Summary of the invention

[0006] In order to achieve the above-mentioned purpose, the technical solution provided in the present application is a door support device for a coal transport train, which includes a support rod, a plug-in block, a plug-in block hanging ring and a hook; one end of the support rod is connected to the plug-in block, a plug-in block hanging ring is provided on the plug-in block, a slot is provided on the plug-in block, and one end of the hook is detachably connected to the plug-in block hanging ring.

[0007] When the support device supports the car door, the other end of the support rod bears against the body of the coal transport train, the free end of the car door is inserted into the slot provided on the plug-in block, and the other end of the hook is detachably connected to the car door.

[0008] Based on the above technical solution, the supporting device has a simple structure. It utilizes the original structure of the coal transport train door and can provide support without destroying the original structure. It is simple to operate and easy to install and disassemble, which can further improve work efficiency.

[0009] Preferably, a support block is provided at one end of the support rod that supports the body of the coal transport train.

[0010] Based on the above technical solution, the setting of the support block can make the support rod supporting one side of the coal train body more stable and reliable.

[0011] Furthermore, the vehicle door comprises a vehicle door body and two locking assemblies symmetrically installed on both sides of the vehicle door body; each locking assembly comprises a hanging ring, an ear plate, two fixed blocks and a rotating pin; the upper part of the vehicle door body is connected to the body axis of the coal transport train, the ear plate is installed at the lower part of the vehicle door body, the hanging ring is rotatably connected to the lower part of the vehicle door body, and when the vehicle door body is in a closed state, two fixed blocks are fixed on the body of the coal transport train below the vehicle door body, and the two fixed blocks are arranged on both sides of the ear plate, and the rotating pin is connected to the fixed block axis on one side, and the rotating pin rotates toward the fixed block on the other side to limit the ear plate between the rotating pin and the body of the coal transport train.

[0012] Furthermore, a supporting device is arranged at each locking assembly position, the supporting block fulcrum is between two fixed blocks, the free end of the ear plate is inserted into a slot provided on the plug-in block, and the other end of the hook is detachably connected to the hanging ring.

[0013] Preferably, the support block is a rectangular plate support block, the fixing block is an L-shaped fixing block, and the lower edge of the rectangular plate support block is placed on the upper parts of the two L-shaped fixing blocks.

[0014] Based on the above technical solution, the L-shaped fixing block can support the rectangular plate supporting block to a certain extent, further improving the supporting stability of the device.

[0015] Furthermore, the support rod is a retractable support rod.

[0016] Based on the above technical solution, the length of the support rod is adjustable, which is more flexible and the application range of the device is wider.

[0017] Preferably, the support rod comprises an inner support rod and an outer support rod, the outer support rod is sleeved on the outer side of the inner support rod, the two can slide relative to each other and are locked by a locking piece.
