Description

Technical Field

[0001] The utility model relates to the field of railway transport vehicles, in particular to a funnel protection device for railway freight vehicles. Background Art

[0002] Railway hopper cars are used to transport bulk minerals such as coal, ore, sand and gravel, cement clinker, and salt, and are capable of self-unloading and unloading while moving. Currently, the bottom doors of railway hopper cars are mainly classified into the following types of structures: longitudinal with longitudinal length and transverse with width, and center unloading (unloading into the center of the track) and side unloading (unloading to the sides of the track). These structures include longitudinal with longitudinal saddle (side unloading), longitudinal without longitudinal saddle (center unloading), and transverse with center unloading.

[0003] The hopper of a railway hopper car is equipped with a reinforcing ridge to increase the strength of the hopper. However, when loading ore, the falling ore will hit the reinforcing ridge. Long-term impact will cause the reinforcing ridge inside the hopper to deform and damage. In addition, the unloading flap at the bottom of the hopper is fixed by a pin. Railway freight cars are long, and it takes a lot of time for workers to pull out the pins one by one to unload the material, which is inconvenient to use. Utility Model Content

[0026] like Figure 1-7 As shown, the opening mechanism 6 includes a positioning seat 601 fixedly installed at the bottom of the reinforcing ridge 5, a stopper 602 is movably installed in the positioning seat 601, a driving gear 603 is connected to the stopper 602, a driving rack 604 is movably installed on one side of the driving gear 603, a driving frame 606 is fixedly installed between the driving racks 604, a trapezoidal lead screw 605 is provided in the middle position of the driving frame 606, a driving motor 607 is provided at one end of the trapezoidal lead screw 605, a first clutch 608 is provided on the trapezoidal lead screw 605, and a second clutch 704 is provided on the transmission shaft 706.

[0027] like Figure 1-4 As shown, a set of L-shaped stop plates 202 are provided on each side of the reinforcement ridge 5. The L-shaped stop plates 202 are arranged opposite each other and are located below the protective ridge 2. The protective reinforcement plate 201 is slidably inserted between the L-shaped stop plates 202. A set of L-shaped stop plates 202 consists of two L-shaped stop plates 202 with openings facing each other. The L-shaped stop plates 202 form a slideway with the sidewalls of the reinforcement ridge 5. The ends of the protective reinforcement plate 201 are inserted through the openings of the L-shaped stop plates 202, facilitating installation and replacement.

[0028] Specifically, the trapezoidal screw rod 605 can be driven to rotate by the driving motor 607. After the trapezoidal screw rod 605 rotates, it will drive the driving frame 606 to move forward, thereby driving the driving rack 604 to move forward, causing the driving gear 603 to rotate, allowing the block 602 to shrink into the positioning seat 601. After the block 602 shrinks into the positioning seat 601, one side of the flap 3 will lose its obstruction, causing the flap 3 to open automatically.

[0029] like Figure 1-7As shown, a rubber pad 4 is fixedly installed in the protective spine 2, and the fixing mechanism 7 includes a mechanism shell 702 fixedly installed on the inner wall of the reinforcing ridge 5, a fixing pin 701 is provided in the mechanism shell 702, a spring 703 is sleeved on the fixing pin 701, a steel wire rope 709 is provided on the fixing pin 701, a winding shaft 708 is movably installed above the trapezoidal lead screw 605, a winding disk 707 is fixedly installed on the winding shaft 708, a transmission shaft 706 is provided between the winding shaft 708 and the driving motor 607, and a bevel gear 705 is provided on both the transmission shaft 706 and the winding shaft 708, and the bevel gears 705 are meshed together.

[0030] Specifically, the rubber pad 4 under the protective spine 2 can absorb the energy generated by the impact and reduce the damage to the reinforcing ridge 5. The driving motor 607 can drive the transmission shaft 706 to rotate. After the transmission shaft 706 rotates, it will drive the winding disk 707 on the winding shaft 708 to rotate. After the winding disk 707 rotates, it will reel in the wire rope 709.

[0031] Working principle: When in use, first place the protective spine 2 above the reinforcing ridge 5. After the protective spine 2 is placed above the reinforcing ridge 5, the spring 703 will push the fixing pin 701 to embed into the protective spine 2, thereby fixing the protective spine 2 on the reinforcing ridge 5. When the ore falls, it will hit the protective spine 2. The rubber pad 4 under the protective spine 2 can absorb the energy generated by the impact and reduce the damage to the reinforcing ridge 5. At the same time, the first clutch 608 can be controlled to engage. After the first clutch 608 is engaged, the drive motor 607 can be started. After starting the drive motor 607, it will drive the trapezoidal lead screw 605 to rotate. After the trapezoidal lead screw 605 rotates, it will drive the drive frame 606 to move forward. When the drive frame 606 moves forward, it will drive the drive rack 604 to move forward, thereby driving The driving gear 603 rotates, and after the driving gear 603 rotates, it will drive the block 602 to rotate, so that the block 602 shrinks into the positioning seat 601, and the flap 3 is installed at the bottom of the funnel body 1 through a hinge. After the block 602 shrinks into the positioning seat 601, one side of the flap 3 will lose its obstruction, so that the flap 3 automatically opens, and the second clutch 704 can be controlled to engage. After the second clutch 704 is engaged, the driving motor 607 will drive the transmission shaft 706 to rotate. After the transmission shaft 706 rotates, it will drive the winding disk 707 on the winding shaft 708 to rotate. After the winding disk 707 rotates, it will reel in the wire rope 709, thereby pulling the fixing pin 701 out of the slot on the protective spine 2, loosening the protective spine 2, and making it easier for users to remove the protective spine 2 for maintenance.
