Description

Technical Field

[0001] This invention relates to the field of rail vehicle technology, and more specifically, to a rail vehicle and its sand-spreading equipment installation structure. Background Technology

[0002] When rail vehicles are on wet, slippery, or steep tracks, the adhesion between the wheels and the rails is insufficient, which can easily lead to slippage. Generally, a sand-spreading device is added to the vehicle to spread sand on the track surface to increase the friction coefficient between the vehicle and the track, thereby better utilizing the vehicle's traction and braking performance.

[0003] Currently, rail vehicles are equipped with sand-spreading devices before leaving the factory. After performance evaluation during the operational commissioning phase, the sand-spreading equipment may be removed or retained. In some cases, due to harsh actual track conditions, it may even be necessary to add sand-spreading equipment to the delivered rail vehicles, leading to modifications to multiple vehicle systems, low installation efficiency, and increased vehicle manufacturing costs. Furthermore, after a period of operation, sand needs to be added to the sand box in the sand-spreading equipment. The sand box is located under the car body, requiring maintenance personnel to add sand from below, creating a confined operating space and posing safety risks.

[0004] In summary, how to provide an installation structure for sand spreading equipment on rail vehicles that can improve the installation efficiency of sand spreading equipment, reduce vehicle manufacturing costs, and enhance the convenience and safety of sand spreading operations for maintenance personnel is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a rail vehicle and its sand-spreading equipment installation structure, which can improve the installation efficiency of the sand-spreading equipment and reduce the vehicle manufacturing cost, as well as improve the convenience and safety of maintenance personnel in sand-spreading operations.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A sand-spreading device installation structure for a rail vehicle includes:

[0008] The vehicle body includes a chassis, on which a sand-passing hole is provided, and a reserved groove is provided on the chassis and around the sand-passing hole, with the opening of the reserved groove facing the outside of the vehicle body;

[0009] A sand-spreading mechanism includes a sand box, which is detachably mounted in the reserved slot, and the open end of the sand box is connected to the sand passage hole;

[0010] A sand-adding mechanism is used to add sand to the sand box, and the sand-adding mechanism is detachably installed inside the vehicle body;

[0011] A connecting pipe is connected at one end to the sand adding mechanism, and the other end of the connecting pipe passes through the sand passage hole and is connected to the open end of the sand box.

[0012] Preferably, the interior of the vehicle body is provided with a seat located above the chassis, the sand-adding mechanism is detachably located at the bottom of the seat, and the sand-passing hole is located below the seat.

[0013] Preferably, the sand-adding mechanism includes a sand-adding box and two guide rails, the two guide rails being respectively disposed on both sides of the bottom of the seat, the sand-adding box being slidably disposed between the two guide rails, and being able to extend out or be hidden in the bottom of the seat.

[0014] Preferably, the guide rail is a telescopic guide rail, which includes a fixed guide rail and a movable guide rail. The fixed guide rail is mounted on the bottom of the seat via a mounting plate, and a portion of the movable guide rail is slidably mounted on the fixed guide rail, while the other portion is connected to the sand filling box.

[0015] Preferably, the connecting pipe includes a sand-adding pipe, a conduit, and a sand inlet pipe. The sand-adding pipe is fixed to the bottom of the sand-adding box, the sand inlet pipe is fixed to the base frame and inserted into the sand passage hole, and the conduit connects the sand-adding pipe and the sand inlet pipe.

[0016] Preferably, the sand inlet pipe is detachably mounted on the base frame, the base frame is covered with a honeycomb plate, the honeycomb plate is provided with a reserved plate at the position opposite to the sand passage hole, and the sand inlet pipe passes through the reserved plate and extends into the sand passage hole.

[0017] Preferably, when the sand box is not installed in the reserved slot, a portion of the sand passage hole and the interior near the vehicle body is filled with fireproof material, and another portion of the sand passage hole and the exterior near the vehicle body is filled with sealing material.

[0018] A rail vehicle includes a sand-spreading device mounting structure for the rail vehicle, wherein the sand-spreading device mounting structure for the rail vehicle is any one of the aforementioned sand-spreading device mounting structures for rail vehicles.

[0019] Compared to the aforementioned background technology, the sand spreading equipment installation structure for rail vehicles provided by this invention has multiple sand passage holes machined on the underframe of the sand spreading equipment installation area during the rail vehicle manufacturing process. Pre-reserved slots are provided on the outer side of the underframe and around each sand passage hole, with the slot openings facing the outside of the vehicle body. Thus, if sand spreading equipment needs to be added after the rail vehicle is delivered, the sand box in the sand spreading mechanism can be directly installed in the pre-reserved slot and located outside the vehicle body. The sand adding mechanism can be installed inside the vehicle body at a corresponding empty position. The open end of the sand box is connected to the sand adding mechanism via a connecting pipe, enabling the sand adding mechanism to add sand into the sand box.

[0020] Therefore, if sand-spreading equipment needs to be added after the rail vehicle has been put into operation and commissioning, the sand-spreading equipment can be installed quickly without significantly affecting the modification of other equipment on the vehicle, thereby improving the installation efficiency of the sand-spreading equipment and reducing the vehicle manufacturing cost. In addition, if sand needs to be added to the sand box, maintenance personnel can enter the vehicle to operate the sand-adding mechanism and add sand to the sand box outside the vehicle through the connecting pipe. This avoids the situation where maintenance personnel are unable to add sand due to limited operating space when adding sand at the bottom of the vehicle, as well as the situation of accidentally touching the electrical equipment at the bottom of the vehicle, thereby improving the convenience and safety of sand-adding operations for maintenance personnel.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] The core of this invention is to provide a rail vehicle and its sand-spreading equipment installation structure, which can improve the installation efficiency of the sand-spreading equipment, reduce the vehicle manufacturing cost, and improve the convenience and safety of maintenance personnel in sand-spreading operations.

[0028] It should be noted that in this embodiment, the orientation or positional relationship indicated by terms such as "upper," "lower," etc., is based on the orientation or positional relationship shown in the accompanying drawings and is only for the convenience of describing this application and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In addition, "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] Please refer to Figure 1 This application provides an installation structure for a sand spreading device for a rail vehicle, including a car body, a sand spreading mechanism, a sand adding mechanism, and a connecting pipe. The car body includes a base frame 1, on which a sand passage hole 2 is provided. A reserved groove 3 is provided on the base frame 1 and around the sand passage hole 2, with the opening of the reserved groove 3 facing the outside of the car body. The sand spreading mechanism includes a sand box 15, which is detachably installed in the reserved groove 3, and the open end of the sand box 15 is connected to the sand passage hole 2. The sand adding mechanism is used to add sand to the sand box 15 and is detachably installed inside the car body. One end of the connecting pipe is connected to the sand adding mechanism, and the other end passes through the sand passage hole 2 and is connected to the open end of the sand box 15.

[0030] It should be noted that the vehicle body consists of a chassis 1, side walls, a roof, and end walls. A bogie is installed below the chassis 1. The sand spreading equipment is installed on the chassis 1 and located in the front area of ​​the bogie, which is the sand spreading equipment installation area, thus shortening the sand spreading path. The sand adding mechanism is located inside the vehicle body, above the chassis 1. A sand passage hole 2 is provided through the chassis 1, and a pre-reserved groove 3 is provided on the lower end face of the chassis 1 around the sand passage hole 2 for installing the sand box 15 in the sand spreading mechanism. A connecting pipe passes through the sand passage hole 2 and connects the sand adding mechanism to the open end of the sand box 15. The sand spreading mechanism also includes other components, such as a sand spreader. Since the specific structural design of the sand spreading mechanism is not the focus of this application, reference can be made to the prior art, and it will not be elaborated further here.

[0031] The sand-spreading equipment installation structure for rail vehicles provided by this invention involves machining a sand-passing hole 2 on the base frame 1 of each sand-spreading equipment installation area during the rail vehicle manufacturing process. Pre-reserved slots 3 are provided on the outer side of the base frame 1 and around each sand-passing hole 2, with the slot openings facing outwards from the vehicle body. Thus, if sand-spreading equipment needs to be added after the rail vehicle is delivered, the sand box 15 in the sand-spreading mechanism can be directly installed in the pre-reserved slot 3 and located outside the vehicle body. The sand-adding mechanism can be installed inside the vehicle body at a corresponding empty position. The open end of the sand box 15 is connected to the sand-adding mechanism via a connecting pipe, enabling the sand-adding mechanism to add sand into the sand box 15.

[0032] Therefore, if sand-spreading equipment needs to be added after the rail vehicle has been commissioned and operational, the equipment can be installed quickly without significantly affecting the other equipment on the vehicle, thereby improving the installation efficiency of the sand-spreading equipment and reducing the vehicle manufacturing cost. In addition, if sand needs to be added to the sand box 15, maintenance personnel can enter the vehicle to operate the sand-adding mechanism and add sand to the sand box 15 outside the vehicle through the connecting pipe. This avoids the situation where maintenance personnel are unable to add sand due to limited operating space when adding sand at the bottom of the vehicle, as well as the situation of accidentally touching the electrical equipment at the bottom of the vehicle, thereby improving the convenience and safety of sand-adding operations for maintenance personnel.

[0033] Based on the above embodiment, the interior of the vehicle body is provided with a seat 14 located above the chassis 1, the sand filling mechanism is detachably located at the bottom of the seat 14, and the sand passage hole 2 is located below the seat 14.

[0034] Specifically, the vehicle body is equipped with multiple seats 14. The sand-adding mechanism is detachably installed at the bottom of the seats 14 located in the sand-spreading equipment installation area. Correspondingly, the base frame 1 is provided with sand-passing holes 2 located below the seats 14. Therefore, the sand-adding mechanism is installed at the bottom of the seats 14 and connected to the sand box 15 outside the vehicle body through a connecting pipe. The installation structure of the sand-adding mechanism makes full use of the space at the bottom of the seats 14 since there is a certain distance between the bottom of the seats 14 and the base frame 1, which can save installation space. At the same time, it does not require changing the installation position of other equipment inside the vehicle body, which can improve installation efficiency.

[0035] Optionally, the sand-adding mechanism can also be installed on the side wall of the vehicle body. Correspondingly, the base frame 1 needs to be provided with sand passage holes 2 and reserved slots 3 so that the sand-adding mechanism inside the vehicle body can be connected to the sand box 15 outside the vehicle body.

[0036] Based on the above embodiments, the sand-adding mechanism includes a sand-adding box 8 and two guide rails 9. The two guide rails 9 are respectively located on both sides of the bottom of the seat 14. The sand-adding box 8 is slidably located between the two guide rails 9 and can extend or be hidden in the bottom of the seat 14.

[0037] Specifically, guide rails 9 are provided on both sides of the bottom of the seat 14 and along its length. One side of the sand filling box 8 is slidably mounted on the first guide rail 9, and the other side is slidably mounted on the second guide rail 9, allowing the sand filling box 8 to slide out of the outside of the seat 14 or slide back into the bottom of the seat 14. When sand filling is required, the maintenance personnel pull the sand filling box 8 outward from the seat 14 to extend it beyond the seat 14, add sand into the sand filling box 8, and the sand enters the sand box 15 through the connecting pipe to complete the sand filling operation. After the sand filling operation is completed, the maintenance personnel push the sand filling box 8 inward from the seat 14 to hide it at the bottom of the seat 14. Therefore, the above structure facilitates sand filling operations for maintenance personnel and improves sand filling efficiency.

[0038] Based on the above embodiments, in order to further improve the convenience of sand adding operation, the guide rail 9 is a telescopic guide rail 9. The telescopic guide rail 9 includes a fixed guide rail 9 and a movable guide rail 9. The fixed guide rail 9 is set at the bottom of the seat 14 through the mounting plate 10. A part of the movable guide rail 9 is slidably set on the fixed guide rail 9 and the other part is connected to the sand adding box 8.

[0039] Specifically, mounting plates 10 are provided on both sides of the bottom of the seat 14 and along its extension direction. Telescopic guide rails 9 are mounted on the seat 14 through the mounting plates 10 to improve the stability of the guide rail structure. The fixed guide rail 9 is fixed to the mounting plate 10, and a portion of the movable guide rail 9 near the inner side of the seat 14 is slidably mounted on the fixed guide rail 9. Another portion of the movable guide rail 9 near the outer side of the seat 14 is fixedly connected to the sand filling box 8. Thus, when the sand filling box 8 is pulled outwards from the seat 14, the other portion of the movable guide rail 9 extends outwards from the seat 14, causing the sand filling box 8 to extend from the bottom of the seat 14, facilitating the addition of sand to the sand filling box 8 by maintenance personnel.

[0040] Based on the above embodiments, the connecting pipe includes a sand-adding pipe 11, a conduit 12, and a sand inlet pipe 13. The sand-adding pipe 11 is fixed to the bottom of the sand-adding box 8, the sand inlet pipe 13 is fixed to the base frame 1 and inserted into the sand passage hole 2, and the conduit 12 is connected between the sand-adding pipe 11 and the sand inlet pipe 13.

[0041] Specifically, the sand filling pipe 11 is fixed to the bottom of the sand filling box 8, the sand inlet pipe 13 is fixed to the base frame 1 and passes through the sand inlet hole 2 to connect to the open end of the sand box 15. The conduit 12 is connected between the sand filling pipe 11 and the sand inlet pipe 13. This facilitates precise control when connecting the sand filling box 8 and the sand box 15. In addition, it should be noted that the conduit 12 is made of flexible hose and has a certain reserved length to meet the requirement that the sand filling box 8 be pulled out a certain distance from the seat 14.

[0042] Based on the above embodiments, please refer to Figure 1 The sand inlet pipe 13 is detachably mounted on the base frame 1. A honeycomb plate 5 is laid on the base frame 1. A reserved plate 4 is provided at the position of the honeycomb plate 5 and the sand passage hole 2. The sand inlet pipe 13 passes through the reserved plate 4 and extends into the sand passage hole 2.

[0043] Specifically, a honeycomb plate 5 is installed on the upper surface of the base frame 1 to enhance the structural strength of the base frame 1, and the sand inlet pipe 13 is installed on the base frame 1 through a flange to facilitate the installation or removal of the sand inlet pipe 13. The honeycomb plate 5 is provided with a reserved plate 4 that matches the size of the flange. The reserved plate 4 covers the sand passage hole 2, and the reserved plate 4 is provided with an opening communicating with the sand passage hole 2 and bolt holes. When the sand spreading equipment needs to be installed, the flange is installed in the bolt holes through bolts to fix the sand inlet pipe 13 to the base frame 1, and passes through the opening of the reserved plate 4 and the sand passage hole to connect to the opening end of the sand box 15 in sequence. When the reserved slot 3 does not need to install the sand box 15, if the sand spreading equipment is installed before, the reserved plate 4 is provided on the sand passage hole 2 to hide the sand passage hole 2, so that the appearance of the base frame 1 is indistinguishable from that of a vehicle without sand spreading equipment.

[0044] Based on the above embodiments, please refer to Figure 1 When the sand box 15 is not installed in the reserved slot 3, the part of the sand passage hole 2 and the interior near the vehicle body is filled with fireproof material 6, and the other part of the sand passage hole 2 and the exterior near the vehicle body is filled with sealing material 7.

[0045] Specifically, the upper end of the sand passage hole 2 is filled with fireproof material 6 to ensure that the entire underframe 1 is fire-resistant, and the lower end of the sand passage hole 2 is filled with sealing material 7 to seal the sand passage hole 2 and ensure the airtightness of the entire vehicle during operation.
