Description

Technical Field

[0001] The utility model belongs to bulk material loading and unloading equipment for railway vehicles, in particular to a C-type dumper system modified from an old O-type dumper system. Background Art

[0002] In recent years, with the development and future planning of national freight railways, in order to improve the railway bulk freight transportation capacity and adapt to the future development trend of high efficiency and environmental protection, the railway department has successively promoted the general railway open wagons (C70, C80E) with a load capacity of 70t and 80t to transport bulk goods (such as coal, ore, etc.). At the same time, the railway department and the National Standardization Committee issued a new version of "GB / T18818-2021 Technical Conditions for Testing of Railway Freight Car Tippers and Bulk Cargo Thawing Wares", which put forward new regulatory requirements for the tipping and dispatching of vehicles by the tipping system.

[0003] At present, many domestic steel enterprises and power enterprises are still equipped with a large number of old-style O-type car dumper systems (KFJ-3 & ZFJ-100), most of which were manufactured and put into production in the 1960s-1980s. The shunting operation mode of the car dumper system is:

[0004] On the heavy vehicle line, fully loaded heavy vehicles enter the dumper by front-pulling trench-type heavy vehicle iron bull traction and unhooking platform, and heavy vehicle pusher pushes the vehicle and slides it into the dumper platform. Since new vehicles such as C70 and C80E use No. 16 or 17 interlocking couplers, unhooking platforms cannot be used for unhooking, so this operation method has long been banned by the railway department. The steel structure of the KFJ-3 and ZFJ-100 dumpers is designed according to the maximum load of 100t, while the total weight of the C80E has reached 107t. The steel structure of this dumper can no longer meet the working conditions of dumping C80E.

[0005] After the car tipper unloads, the empty car is pushed into the transfer platform by the empty car pusher, and then the transfer platform transfers the empty car to the empty car line. The transfer platform is self-propelled. After reaching the empty car line, the pusher on the transfer platform pushes the empty car out and slides it to the empty car line to assemble into a row.

[0006] The above-mentioned car tipping and shunting operation methods are expressly prohibited by the railway department. They do not meet the standard requirements of the "GB / T18818-2021 Technical Conditions for Inspection of Railway Freight Car Tippers and Bulk Cargo Thawing Warehouses". The currently advanced C-type car tipping system in China is mainly composed of a C-type car tipping machine, a heavy car shunting machine, an empty car shunting machine, a car transfer platform, a wheel clamp and other equipment. During the car tipping and shunting operations, the system makes the railway vehicles fully controllable, and the entire operation process can meet the requirements of the "GB / T18818-2021" standard.

[0007] In summary, the existing backward old O-type dumper system must be transformed into an advanced C-type dumper system. The system's unloading capacity and ability to adapt to new railway open wagons must be improved. Therefore, it is necessary to research and develop a system layout design and civil construction process to transform the old O-type dumper system (KFJ-3 & ZFJ-100) into a C-type dumper system. Summary of the invention

[0008] The purpose of the utility model is to solve the deficiencies in the above-mentioned technologies and provide a C-type car tipper system modified from an old-style O-type car tipper system. The system is improved on the basis of the existing old-style O-type car tipper system (KFJ-3 type & ZFJ-100 type), retaining the car tipper and car transfer platform foundation, and re-manufacturing the heavy car shunting machine, empty car shunting machine, and wheel clamp foundation. In this way, the old-style O-type car tipper system (KFJ-3 type & ZFJ-100 type) is changed to a C-type car tipper system, and the unloading capacity of the existing car tipper unloading system is improved, so that it can not only normally receive and unload new railway open cars (C70, C80E), but also meet the standard requirements of the GB / T18818-2021 standard.

[0009] The original O-type car tipping machine system includes an O-type car tipping machine, a heavy car iron bull, an empty car iron bull, a decoupling platform or a car pusher, a car transfer platform, and an empty car pusher. The system is a return car tipping machine system. The shunting operation mode of the car tipping machine system is as follows: on the heavy car line, the heavy car iron bull pulls the fully loaded heavy car train to the decoupling platform and retreats to the ditch to wait. The vehicle to be unloaded on the decoupling platform is manually disconnected from the heavy car train behind, and the decoupling platform is lifted to decouple it from the heavy car train. The vehicle to be unloaded is automatically slid onto the car tipping machine platform through the tilting angle. The car pusher on the car tipping machine platform pushes the wheel part of the unloaded empty car to make it slide into the car transfer platform, and then the car transfer platform transfers the empty car to the empty car line. After arriving at the empty car line, the empty car pusher on the car transfer platform pushes the empty car out and slid it to the empty car line to assemble into a line. Finally, the empty car iron bull installed on the empty car line pushes the empty car train to the designated position.

[0010] The technical solution of the utility model is implemented as follows: the improved C-type car tipping machine system of the utility model is a return car tipping machine system, comprising a C-type car tipping machine (7), a heavy car shunting machine (8), an empty car shunting machine (9), a car transfer platform (10), a track readjustment device (11), an air conditioning track device (12), a wheel clamp (13) and a safety stopper (14);

[0011] The C-type tipping machine foundation (15) and the car transfer platform foundation (16) adopt the foundation of the original O-type tipping machine system;

[0012] A track readjustment device foundation (17) is provided outside the heavy vehicle track and parallel to the heavy vehicle track;

[0013] An air-conditioning track device foundation (18) is provided outside the empty car line and parallel to the empty car line;

[0014] A wheel clamp foundation (19) is provided in front of the entrance of the heavy vehicle line tipping machine;

[0015] A safety stopper foundation (21) is provided on the ground at the entrance of the heavy vehicle line transfer platform and the exit of the empty vehicle line transfer platform;

[0016] A heavy vehicle shunting machine (8) is arranged on the side of the C-type car dumper foundation (15), and a heavy vehicle shunting machine track device (11) is arranged parallel to the heavy vehicle line; an empty vehicle shunting machine (9) and an air-conditioning track device (12) are arranged outside the empty vehicle line and the car transfer platform (10) foundation pit.

[0017] Furthermore, the vehicle transfer platform (10) is a pin-gear transmission type vehicle transfer platform.

[0018] Furthermore, the rooting method under the beam of the re-adjustment track device foundation (17) is to use artificially hollowed cast-in-place piles (20), the pile foundation inside the factory building is located in the middle of the original factory building column foundation, and the pile foundation outside the factory building is set in a number according to the length of the re-adjustment track.

[0019] Furthermore, the air conditioning rail device foundation (18) adopts a natural foundation.

[0020] The shunting operation method of the car tipping machine system is: the empty car parked in the car tipping machine in the previous working cycle is numbered as car 1#, the one to be tipped is car 2#, and the one coupled to car 2# is car 3#.

[0021] The heavy vehicle shunting locomotive pulls the entire train forward slowly, causing the coupler between the 2# and 3# cars to stop at a certain distance from the center of the wheel clamp.

[0022] Manually open the 2# and 3# vehicle coupling trailer hooks and clamp the wheel clamps.

[0023] The heavy vehicle shunting locomotive pulls car No. 2 forward and connects with car No. 1.

[0024] The heavy vehicle shunting machine pulls the No. 2 vehicle into position inside the tipping machine.

[0025] The heavy vehicle shunting machine automatically uncouples from the No. 2 vehicle.

[0026] The heavy vehicle shunting machine pushes the No. 1 vehicle to position it in the vehicle transfer platform.

[0027] At the same time, the dumper performs dumping operations and then returns to its original position.

[0028] The heavy vehicle shunting machine automatically uncouples from the No. 1 vehicle.

[0029] The car transfer platform moves toward the empty car line and aligns with the empty car line.

[0030] At the same time, the boom of the heavy vehicle shunting machine is lifted and returned to its original position.

[0031] The empty car shunting locomotive pushes the empty cars out of the car transfer platform, assembles them into rows on the empty car line, and the car transfer platform returns to the loaded car line.

[0032] The boom of the heavy vehicle shunting machine descends, then moves backward to couple with the next vehicle.

[0033] At this point, one working cycle is completed and the next working cycle begins, and the operation is repeated in this way.

[0034] The operation mode of the C-type car tipping machine system is more advanced than the old O-type car tipping machine system, and the railway vehicle can be fully controlled during the entire operation process.

[0035] The structural and civil construction plan for changing the old O-type dumper system (KFJ-3 & ZFJ-100) to a C-type dumper system:

[0036] a. Keep the civil engineering foundation of the original O-type tipper system and directly replace the O-type tipper with a C-type tipper on it.

[0037] b. The civil engineering foundation of the original O-type car tipping machine system's car transfer platform is retained, and the old car transfer platform (self-propelled) is directly replaced with the new car transfer platform (pin-gear transmission) on it.

[0038] c. All the original vehicle dispatching equipment including heavy vehicle iron oxen, unhooking platforms, vehicle pushers, empty vehicle iron oxen, etc. on the heavy and empty vehicle lines are removed, and the civil engineering foundation is scrapped and backfilled.

[0039] d. Without dismantling the original dumper plant, a new re-adjustment track device foundation is built on the side of the original O-type dumper body foundation parallel to the heavy vehicle line. Due to the heavy vehicle shunting machine load, without destroying the original O-type dumper system plant column, the rooting method under the entire re-adjustment track device foundation beam is to use artificially dug bored piles. The pile foundation inside the plant is located in the middle of the original plant column foundation, and the pile foundation outside the plant is set according to the length of the re-adjustment track.

[0040] e. Build a new foundation for the air-conditioning track device outside the empty car line and parallel to the empty car line. Since the load of the empty car shunting machine is small, the foundation adopts the natural foundation.

[0041] f. Build a new wheel clamp foundation in front of the entrance of the heavy vehicle line tipping machine, and build a new safety stopper foundation on the ground at the entrance of the heavy vehicle line transfer platform and the exit of the empty vehicle line transfer platform.

[0042] Compared with the prior art, the utility model has the following advantages:

[0043] (1) The system layout design and civil construction technology of the utility model, which changes the old O-type tipping machine system (KFJ-3 type & ZFJ-100 type) into a C-type tipping machine system, are the first in China. The modified tipping machine system has high operating efficiency, high degree of automation and little damage to vehicles.
