Description

Technical Field

[0001] The invention relates to the technical field of a special support vehicle for railway freight cars, and in particular to a support vehicle used in conjunction with a special railway insulation vehicle. Background Art

[0002] Liquid and gas special cargoes are generally placed in cylindrical or tank containers for transportation due to their flammability, explosiveness, and sensitivity to temperature. Such cargoes with large volume, mass, and long-distance transportation are usually transported by special railway insulated transport vehicles. The basic process is: place the support vehicle on a loading and unloading flat car with tracks (standard gauge), lift the container onto the support vehicle through lifting equipment, lock it with the support vehicle, and then push the support vehicle into an adjacent insulated transport vehicle with tracks (standard gauge). Next, lock the support vehicle with the insulated transport vehicle. During transportation, the container is always placed on the support vehicle, and the reverse order is followed when unloading the cargo. It can be seen that the support vehicle plays a very important role in the transportation of special cargoes.

[0003] The Chinese patent "A railway dangerous goods transport vehicle", publication number CN212529629U, announcement date 2021.02.12, discloses a railway dangerous goods transport vehicle, which is a frame-shaped device body welded together with a base plate, four vertical bars, two horizontal bars and two side bars for placing tanks of dangerous goods. By pre-assembling the frame-shaped device body and the tanks of dangerous goods, it is possible to save transportation time and loading time, improve work efficiency, and install an arc seat on the base plate, and connect the arc seat box to the base plate through a number of springs. The arc seat with an arc surface can provide stable support for the tank of dangerous goods, and the spring can provide a buffering effect between the arc seat and the tank of dangerous goods, and the slide groove and slide convexity ensure the stability of the arc seat.

[0004] The Chinese patent "A new type of dangerous goods transport vehicle frame", publication number CN209534867U, announcement date 2019.10.25, discloses a new type of dangerous goods transport vehicle frame, which is provided with an arc-shaped rubber pad and an arc-shaped support plate, and the tank body containing dangerous goods is fixed by bolts passing through the mounting screw holes, and then the cylinder is started, and the output end of the cylinder drives the arc-shaped support plate to move, and the arc-shaped support plate drives the arc-shaped rubber pad to move through the spring, and then the arc-shaped rubber pad is tightly attached to the outer walls of both sides of the tank body. When the car tilts during the formation process, the tank body squeezes the corresponding arc-shaped rubber pad, and the arc-shaped rubber pad squeezes the spring. Under the buffering effect, the tilting tendency of the tank body can be prevented, and the stability of the tank body containing dangerous goods when being transported by car can be effectively guaranteed, and the safety is high; by providing an adjusting groove and a sliding plate, the sliding plate can be moved left and right at the top of the crossbeam through the adjusting groove, so that the distance between the two sliding plates can be adjusted, thereby moving the arc-shaped support plate installed thereon, and then the distance between the two arc-shaped rubber pads can be adjusted, and then the sliding plate is fixed by passing the positioning bolt through the positioning screw hole, and the distance between the two arc-shaped rubber pads can be adjusted according to the size of the tank body, so that the arc-shaped rubber pad can be tightly attached to the outer wall of tank bodies of different sizes, with a wide range of applications and high practicality.

[0005] The existing support structure must be locked with the corresponding lock seat of the tank body. There is a gap between the locking device and the tank lock seat, and it does not bear the weight of the tank body. At the same time, due to the long container, there will be a certain manufacturing error in the height of the three support structures. The center of gravity of the tank body is in the middle position. When the middle bracket is higher or lower than the front and rear brackets, it may cause uneven bearing capacity of the three support seats, thereby affecting the transportation stability of the tank body.

[0006] In other words, the existing large-volume and heavy-mass cylindrical or filling containers are unstable in installation and fixation, the height in the middle of the tank body is inconsistent with the two ends, and there is a lack of support or excessive support, which poses a safety hazard.

[0035] The technical solution of the present invention (including the preferred technical solution) is further described in detail below by means of the accompanying drawings and by listing some optional embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] like Figure 1 to Figure 4 As shown, the railway insulation vehicle support vehicle designed by the present invention includes a plurality of lock seat groups arranged on a transport container, which are distributed into a front lock seat group 1, a middle lock seat group 2, and a rear lock seat group 3 according to the arrangement position.

[0037] like Figure 5 and Figure 6 As shown, the railway insulation vehicle support vehicle designed by the present invention includes support seats that are independently adapted to multiple lock seat groups to lock the transport container; according to the layout position, it includes an independently arranged front support seat 4, a middle support seat 5 and a rear support seat 6.

[0038] like Figure 7 to Figure 12 As shown, the front support seat, the middle support seat and the rear support seat all include: a frame 7; the frame 7 is provided with a bracket 8 for carrying a transport container, a wheel train 9 for carrying the frame 7, and a plurality of baffles 10 for fixing to a transport and insulation vehicle; the top of the bracket 8 is an arc-shaped surface adapted to the outer wall of the transport container; the frame 7 is provided with a plurality of pull rings 11 for fixing to a transport and insulation vehicle at intervals around it.

[0039] Four wheel trains 9 are provided on the front support seat 4, the middle support seat 5 and the rear support seat 6, so that they can move on the standard track with a track gauge of 1435 mm. In order to prevent the support seat from slipping off the track during movement, wheel flanges are provided on the wheels. The wheels are driven by bearings, which effectively reduces the resistance of pushing the support seat carrying the tank body from the loading and unloading flat car into the transport insulation car.

[0040] The frame 7 and bracket 8 are welded by channel steel and steel plate. The support width and the diameter of the support arc of the bracket 8 are determined by the diameter of the goods. Thick felt is pasted on it to effectively protect the surface of the product from loss. There are 4 pull rings 11 and 2 baffles 10 on both sides of the frame 7 for fixing with the transport insulation vehicle. Each baffle 10 is fixed to the frame 7 by bolts, and two round holes are provided on the baffle 10 for connecting with the locking device on the floor of the transport insulation vehicle.

[0041] The front support seat 4 is locked with the lock seat assembly at the front end of the transport container through a locking structure. The locking structure includes: a slide rail 4.1 fixed to the front support seat frame, a Z-shaped block 4.2 slidably connected to the slide rail 4.1, and the Z-shaped block 4.2 is locked with the slide rail 4.1 through a locking bolt; a buckle plate 4.21 is provided on the top of the Z-shaped block 4.2, and a buckle hole 1.1 adapted to the buckle plate 4.21 is provided on the lock seat assembly at the front end of the transport container; the buckle plate 4.21 is inserted into the buckle hole 1.1 to lock the transport container and the front support seat 4.

[0042] The locking structure consists of a set of Z-shaped blocks 4.2 and slide rails 4.1 on the left and right, which are fixed to the frame 7 with bolts. Manually slide the Z-shaped blocks 4.2 on both sides inward to buckle the front lock seat group 1 of the transport container, and then insert three locking bolts into the slide rails 4.1 and Z-shaped blocks 4.2 and tighten them to complete the locking operation. To loosen, follow the reverse operation.

[0043] The middle support seat 5 is locked with the middle lock seat group 2 of the transport container through a rotating lock device 12, and the rear support seat 6 is locked with the transport container through a rotating lock device 12 and the rear lock seat group 3 of the transport container.

[0044] like Fig.11 , Figure 13 to Figure 15 As shown, the rotary lock device 12 comprises: a U-shaped rod 12.1, with a seat plate 12.2 fixed to the frame 7 at each end of the U-shaped rod 12.1; a load-bearing bin 12.3 fixed on the seat plate 12.2 and with an open side wall; a rotating shaft rotatably connected to the top of the load-bearing bin 12.3; one end of the rotating shaft passes through the top of the load-bearing bin 12.3 and is fixedly connected to a rotary lock 12.4, and the other end is fixedly connected to a lever 12.5; the two ends of the U-shaped rod 12.1 are respectively hinged to the lever 12.5; a limit buckle 12.6 is provided on the inner wall of the load-bearing bin 12.3, and the U-shaped rod 12.1 is locked when the U-shaped rod 12.1 is in the extreme position; the U-shaped rod 12.1 is shifted horizontally along the support vehicle to drive the rotary lock 12.4 to rotate and cooperate with the limit buckle 12.6 to lock the transport container.

[0045] In some optional embodiments of the present invention, the seat plate 12.2 is provided with a stop bolt 12.7 for limiting the locking of the U-shaped rod 12.1 at the limit position, so as to further ensure that after the transport container is locked, the U-shaped rod will not deviate from the limit position to cause the rotary lock 12.4 to rotate, thereby ensuring reliable locking.

[0046] In some optional embodiments of the present invention, a handle 12.8 is provided on the U-shaped rod 12.1, so that the U-shaped rod 12.1 can be easily moved.

[0047] Unscrew the stop bolts 12.7 on both sides, hold the handle 12.8 and pull it first, then push the U-shaped rod 12.1, so that the U-shaped rod 12.1 drives the rotary lock 12.4 to rotate 90° counterclockwise through the rotating shaft, and then tighten the stop bolt 12.7 on the right to complete the locking.

[0048] In some optional embodiments of the present invention, the middle support seat 5 further comprises: a spiral elevator 13 that carries the bracket 8 , and the height of the bracket of the middle support seat is adjusted by adjusting the spiral elevator 13 .

[0049] Four sets of identical disc spring groups are arranged above the wheel train 9 to provide elastic support for the frame 7, thereby transmitting the elastic support to the transport container, so as to exert force on the front, middle and rear of the transport container.

[0050] Two sets of identical screw lifts 13 are arranged at symmetrical positions on both sides below the bracket 8, and a pressure sensor, a scale and a display panel 14 are arranged on the middle support seat, so that the height of the bracket can be manually adjusted and the bearing capacity of the bracket at different heights can be read.

[0051] To ensure the stability of the insulated transport vehicle during transportation, the combined center of gravity of the rack truck and the product should be close to or coincide with the center of gravity (i.e., geometric center) of the transport vehicle, and there should be no obvious overloading. To ensure the stability of the vehicle at the standard transportation speed, the center of gravity of the rack truck should be as low as possible; the position of the rack truck and the tank cargo in the vehicle compartment is determined by the center of gravity of the insulated truck. The specific process is as follows:

[0052] 1) Adjust the height of the middle support seat so that it is lower than the front and rear support seats;

[0053] 2) The tank cargo support is transferred to the support vehicle placed on the transition flat car. Since the tank has great strength and rigidity, it is allowed to temporarily use the front and rear support seats to support it, and lock the front and rear support seats with the tank;

[0054] 3) Adjust the middle support seat to make it rise slowly until the load-bearing capacity displayed on the display screen is one-third of the tank weight, then stop rising and maintain the height, and lock the middle support seat with the tank body. At this time, the three support seats are evenly loaded, and the support vehicle is in a stable supporting state;

[0055] 4) Push the product into the railway transport insulation vehicle;

[0056] 5) Bolt the baffles of the three support seats of the support vehicle to the baffle seats preset on the floor of the insulation vehicle.

[0057] 6) Use a double-ended threaded hook to connect the pull rings of each support seat to the pull ring seat preset on the floor and tighten them. Fig.16 shown.

[0058] When unloading cargo, follow the reverse order.

[0059] Those skilled in the art will readily appreciate that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, combinations, replacements, improvements, etc. made within the spirit and principles of the present invention are included within the protection scope of the present invention.
