Description
Technical Field
[0001] The utility model relates to the technical field of subways, in particular to a small flat car for transporting ballast on a subway gravel roadbed. Background Art
[0002] The subway is a type of urban rail transit line system, which refers to a fast, large-capacity, electrically tractioned rail transit built in the city. The track bed of the subway vehicle depot is generally made of gravel, which requires regular ballasting and tamping, especially after the new line is opened, which requires a large amount of ballasting operations.
[0003] At present, the ballast replenishment method generally adopts ballast transporting trolley. After the ballast is loaded on the ballast transporting trolley and transported to the corresponding position, the operator uses a rake to unload the ballast. Since the baffle of the ballast transporting trolley is low, the amount of ballast loaded each time is small, and the ballast replenishment operation requires back and forth transportation. In addition, the bottom plate of the ballast transporting trolley adopts a flat plate design, and the ballast unloading is laborious and time-consuming, and the operation efficiency is low. In order to solve the above technical problems, we have designed a rail ballast transporting flatbed trolley for subway gravel roadbed. Utility Model Content
[0004] The purpose of the utility model is to provide a small rail ballast transport flat car for subway gravel roadbed, which has the advantages of increasing the loading capacity of the flat car, eliminating the need for frequent ballast replenishment, and being able to automatically unload, saving time and effort in ballast unloading and improving operating efficiency. It solves the problems of low baffles, small ballast loading capacity, flat bottom plates, large ballast unloading workload, time-consuming and labor-intensive operation, and low operating efficiency.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a rail ballast transport flat car for subway gravel roadbed, comprising a base plate, a material storage box welded to the top of the base plate, a material guide slope welded to the bottom of the inner cavity of the material storage box, discharge openings are provided at the bottom of the left and right sides of the material storage box, the rear sides of the left and right sides of the material storage box are movably connected with movable baffles, and the front side of the outer side of the movable baffle is connected to a clamping plate through a movable pin.
[0006] Preferably, wheels are connected to the four corners of the bottom of the base plate by bolts, and a pull rod is welded to the rear side of the inner cavity of the storage box.
[0007] Preferably, the pull rod includes a plug-in sleeve, a positioning bolt is threadedly connected to the top of the rear side of the plug-in sleeve, a connecting slide rod is slidably connected to the top of the plug-in sleeve, and a push handle is welded to the top of the connecting slide rod.
[0008] Preferably, the four corners of the inner cavity of the material storage box are welded with material guide vertical plates, and the front side of the outer side of the clamping plate is fixedly connected with a push block.
[0009] Preferably, a storage shell is fixedly connected to the front side of the storage box, and a hinge is installed between the rear side of the outer side of the movable baffle and the storage box.
[0010] Preferably, a clamping block is welded on the front sides of the left and right sides of the storage box, and a clamping slot is provided on the top of the clamping block.
[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0012] The increased height of the storage box can greatly increase the loading capacity of ballast. When the movable baffles on both sides are opened, the ballast flows out from the discharge opening along the slopes on both sides of the guide slope, which increases the loading capacity of ballast and eliminates the need for personnel to frequently perform ballast replenishment operations. At the same time, personnel no longer need to use rakes to unload ballast from the flat car, which saves time and effort and greatly improves work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] See also Figure 1-Figure 5 A small flat car for transporting ballast on a subway gravel roadbed comprises a base plate 1, a material storage box 3 is welded on the top of the base plate 1, a material guide slope 10 is welded on the bottom of the inner cavity of the material storage box 3, a discharge opening 12 is opened on the bottom of the left and right sides of the material storage box 3, and a movable baffle 8 is movably connected to the rear side of the left and right sides of the material storage box 3. The front side of the outer side of the movable baffle 8 is connected to a clamping plate 9 through a movable pin. By setting the clamping plate 9, it can be inserted into the inside of the clamping block 11 to close the movable baffle 8;
[0020] See also Figure 1The four corners of the bottom of the base plate 1 are connected to the wheels 2 by bolts, and the rear side of the inner cavity of the storage box 3 is welded with a pull rod 6. By setting the pull rod 6, it is convenient for personnel to pull the device to walk on the track;
[0021] See also Figure 5 The pull rod 6 includes a plug-in sleeve 16, a positioning bolt 17 is threadedly connected to the top of the plug-in sleeve 16, a connecting slide rod 15 is slidably connected to the top of the connecting slide rod 15, and a push handle 14 is welded to the top of the connecting slide rod 15. When the height of the operator is different, the height of the pull rod 6 can be adjusted accordingly according to his or her height. After loosening the positioning bolts 17 on both sides, the push handle 14 is pushed upward or downward. The connecting slide rod 15 moves upward or downward in the plug-in sleeve 16 to change the height of the pull rod 6. This can improve the comfort of people of different heights when pulling the device;
[0022] See also Figure 1 and Figure 4 The four corners of the inner cavity of the storage box 3 are welded with material guide vertical plates 5. By setting the material guide vertical plates 5, the stone slag in the storage box 3 can be prevented from being stuck in the four corners inside, so that the stone slag in the four corners can be discharged smoothly. The front side of the outer side of the card plate 9 is fixedly connected with a push block 13. By setting the push block 13, it is convenient to push the card plate 9 to rotate upward;
[0023] See also Figure 1 The front side of the storage box 3 is fixedly connected to a storage shell 4. By setting the storage shell 4, construction tools can be stored conveniently to improve practicality. A hinge 7 is installed between the rear side of the outer side of the movable baffle 8 and the storage box 3;
[0024] See also Figure 4 The front sides of the left and right sides of the storage box 3 are welded with card blocks 11, and the top of the card block 11 is provided with a card slot. By setting the card slot, the card plate 9 can be easily inserted into the inside of the card block 11.
[0025] When in use, the storage box 3 is welded at the edge of the top of the base plate 1. Due to the increased height of the storage box 3, the loading capacity of the ballast can be greatly increased. At the same time, a guide slope 10 is welded at the bottom of the storage box 3, and a discharge opening 12 is opened at the bottom on both sides of the storage box 3. The storage box 3 is full of ballast. When the movable baffles 8 on both sides are opened, the internal ballast automatically flows out from the discharge openings 12 on both sides along the slopes on both sides of the guide slope 10 under the action of gravity. This increases the loading capacity of the ballast and does not require personnel to frequently perform ballast replenishment operations. At the same time, the ballast can automatically flow out of the storage box 3, and there is no need for personnel to use a rake to unload the ballast from the flat car, which saves time and effort and greatly improves work efficiency.
[0026] In summary, the subway gravel track ballast transport flatbed car, through the coordinated use of the base plate 1, the storage box 3, the pull rod 6, the movable baffle 8, the clamping plate 9, the guide slope 10, the clamping block 11 and the discharge opening 12, solves the problems of a low baffle, a small ballast loading capacity, a flat bottom plate, a large workload for unloading ballast, time-consuming and labor-intensive operation, and low operating efficiency.
