Description

Technical Field

[0001] This utility model belongs to the field of rail vehicles, specifically a new type of rail vehicle frame. Background Technology

[0002] The lightweight railcar chassis structure is the core load-bearing component of a railcar, mainly used to support the main body of the car and install the running gear. Its performance directly affects the railcar's operational stability, load-bearing capacity, and energy consumption level. This structure needs to reduce its own weight by optimizing the structural design and selecting lightweight materials while ensuring sufficient strength and rigidity, so as to reduce the railcar's operating energy consumption. At the same time, it needs to meet the requirements of different models for chassis installation accuracy and functional expandability. It is a key component for improving the overall performance of railcars.

[0003] Currently, in the existing railcar chassis structure, most equipment mounting components are fixed and cannot be adjusted. If maintenance is required after the additional equipment is installed, it is necessary to disassemble part of the main structure of the railcar before the equipment can be removed. The operation process is cumbersome, which not only prolongs the maintenance time, but may also cause secondary damage to the chassis during the disassembly process. Utility Model Content

[0004] The purpose of this utility model is to provide a new type of rail vehicle frame to solve the problem in the prior art that if additional equipment needs to be maintained after installation, it is necessary to disassemble part of the main structure of the rail vehicle before the equipment can be removed, which is a cumbersome operation process.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel rail vehicle frame, comprising a frame body, a fixing ring, and a mounting frame; a threaded rod is movably installed on one side of the frame body, a fixing ring is movably installed on one side of the frame body, and a limiting rod is fixedly connected to one side of the frame body; a fixing hole is provided at one end of the frame body, and mounting frames are movably installed on both sides of the frame body; limiting grooves are provided inside the frame body on both sides of the mounting frame; limiting blocks are fixedly connected to both sides of the mounting frame, and the limiting blocks are engaged with the limiting grooves; a lead screw is movably installed at one end of the mounting frame.

[0006] Preferably, a screw hole is provided on the other side of the interior of the frame, and the threaded rod is threadedly connected to the screw hole.

[0007] Preferably, connecting frames are fixedly connected to both sides of the bottom of the frame, and the connecting frames are provided with shaft grooves inside.

[0008] Preferably, the bottom of the mounting bracket is provided with bolt holes, and there are several bolt holes.

[0009] Preferably, the bottom of the frame body is provided with a movable groove, and the mounting frame is fitted into the movable groove.

[0010] Preferably, a handle is fixedly connected to one end of the mounting bracket at the bottom of the lead screw, and a rubber sleeve is provided around the handle.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This utility model installs the railcar auxiliary equipment inside the mounting frame and fixes it with screw rods, enabling the base frame structure to stably support the equipment. This breaks through the limitation of the traditional base frame having only one function and effectively expands the functionality of the device. At the same time, by loosening the screw rods, the mounting frame can be pulled out along the limiting groove to quickly remove the equipment, eliminating the tedious steps of disassembling the railcar, significantly reducing the difficulty of maintenance operations, and greatly improving the efficiency of equipment maintenance.

[0013] 2. This utility model achieves the initial positioning of adjacent devices by the engagement of the fixing ring and the limiting rod, and completes the splicing of multiple devices with the rigid connection of the threaded rod. This allows the chassis structure to be flexibly combined to form a larger load-bearing system, meeting the installation requirements of vehicle bodies of different lengths and greatly expanding the applicable scenarios of the device. Moreover, the splicing process is simple to operate and the connection is stable, which improves the flexibility and practical value of the chassis structure. Attached Figure Description

[0021] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0022] As attached Figure 1 To be continued Figure 4 As shown:

[0023] Example 1: This utility model provides a novel rail vehicle frame, including a frame body 2, a fixing ring 3, and a mounting frame 4; a fixing hole 204 is provided at one end inside the frame body 2, and the mounting frame 4 is movably installed on both sides inside the frame body 2. Limiting grooves 202 are provided inside the frame body 2 on both sides of the mounting frame 4, and limiting blocks 402 are fixedly connected to both sides of the mounting frame 4, and the limiting blocks 402 are engaged with the limiting grooves 202. A lead screw 403 is movably installed at one end of the mounting frame 4.

[0024] During the use of this lightweight railcar chassis structure, the staff can first place the auxiliary equipment inside the mounting frame 4 according to the installation requirements of the railcar auxiliary equipment. Then, by rotating the screw 403 at one end of the mounting frame 4, the mounting frame 4 and the frame 2 are firmly connected by the cooperation between the screw 403 and the frame 2, so that the auxiliary equipment is reliably fixed on the chassis structure. At this time, the frame 2, as the core load-bearing component, can effectively distribute the weight of the auxiliary equipment and ensure that the device can stably support the equipment. This breaks through the limitation of the traditional chassis that can only bear the basic support function and significantly increases the functionality of the device. When the auxiliary equipment needs maintenance, the staff only needs to rotate the screw 403 in the opposite direction to unscrew the screw 403 from the frame 2. Then, with the help of the interlocking and guiding effect of the limiting blocks 402 on both sides of the mounting frame 4 and the limiting groove 202 inside the frame 2, the mounting frame 4 can be pulled forward to quickly pull the auxiliary equipment out from inside the frame 2. The entire maintenance process does not require the complete disassembly of the railcar, which greatly simplifies the operation process, reduces the difficulty of operation, and significantly shortens the maintenance time, effectively improving maintenance efficiency.

[0025] In one embodiment of this utility model, a screw hole 201 is provided on the other side of the inside of the frame 2, and the threaded rod 1 is threadedly connected to the screw hole 201.

[0026] The screw hole 201 on the other side of the frame 2 forms a threaded connection with the threaded rod 1. When the threaded rod 1 is rotated, the threaded rod 1 can move axially along the threaded trajectory of the screw hole 201. When assembling multiple devices, the workers can screw the threaded rod 1 of the adjacent devices into the screw hole 201 to fix and connect the multiple devices.

[0027] In one embodiment of the present invention, connecting frames 5 are fixedly connected to both sides of the bottom of the frame 2, and the connecting frames 5 are provided with shaft grooves 501 inside.

[0028] The connecting frames 5 on both sides of the bottom of the frame 2 and the shaft grooves 501 inside are mainly used to connect with the running parts and other related components of the railcar. The shaft grooves 501 can be adapted to the corresponding shaft structure, so that the connecting frame 5 can stably bear the force transmitted by the running parts, and evenly transmit the load during the operation of the railcar to the frame 2, ensuring the stability of the connection between the base frame and the running parts and the effective transmission of force, thus ensuring the normal operation of the railcar.

[0029] In one embodiment of this utility model, the bottom of the mounting bracket 4 is provided with bolt holes 401, and there are several bolt holes 401.

[0030] The mounting bracket 4 has several bolt holes 401 at its bottom, providing multiple connection points for fixing the equipment and accessories of the railcar. By selecting bolt holes 401 at different positions, the position of the installed parts can be flexibly adjusted to meet the fixing requirements of parts of different specifications or different installation needs, thus enhancing the versatility and installation flexibility of the mounting bracket 4.

[0031] In one embodiment of the present invention, a movable groove 203 is provided at the bottom of the frame 2, and the mounting bracket 4 is fitted into the movable groove 203.

[0032] When adjusting the mounting bracket 4, the movable groove 203 can limit the movement trajectory of the mounting bracket 4, prevent it from deviating or shaking during movement, and ensure that the mounting bracket 4 always moves stably in the preset direction. In conjunction with the function of the limit block 402 and the limit groove 202, the accuracy and stability of the movement of the mounting bracket 4 are further improved.

[0033] In one embodiment of this utility model, a handle 404 is fixedly connected to one end of the mounting bracket 4 at the bottom of the lead screw 403, and a rubber sleeve is provided around the handle 404.

[0034] The handle 404 at one end of the mounting bracket 4 at the bottom of the lead screw 403 makes it easy for the operator to pull out the mounting bracket 4. The rubber sleeve 13 around the handle 404 can increase the friction between the hand and the handle 404, prevent slippage during operation, and improve the convenience and comfort of operation.

[0035] Working principle: The operator can directly place the additional equipment required for the railcar inside the mounting frame 4. By tightening the screw 403 at the end of the mounting frame 4, the screw 403 is rigidly connected to the frame 2, thereby stably locking the mounting frame 4 and the equipment inside the frame 2. The frame 2 distributes the equipment load through its own structural strength, ensuring that the device has reliable load-bearing capacity and expanding the functional boundaries of the base frame. When the equipment needs maintenance, simply loosen the screw 403 to release the lock, and use the limiting blocks 402 on both sides of the mounting frame 4 to slide along the limiting groove 202 inside the frame 2 to pull the mounting frame 4 forward to remove the equipment from the frame 2. There is no need to disassemble the main body of the railcar, which greatly simplifies the maintenance operation process and improves the convenience of equipment maintenance.

[0036] Example 2: This example is basically the same as the previous example, except that a threaded rod 1 is movably installed on one side of the inside of the frame 2, a fixing ring 3 is movably installed on one side of the frame 2, and a limit rod 6 is fixedly connected to one side of the inside of the frame 2.

[0037] When multiple lightweight railcar chassis structures need to be assembled in a practical application to form a larger chassis to support a longer car body, the operator can first align the frames 2 of two adjacent chassis structures. Next, the fixing ring 3 on one chassis structure is fastened to the outer periphery of the limiting rod 6 inside the frame 2 of the other chassis structure. Through the cooperation of the fixing ring 3 and the limiting rod 6, the two chassis structures are initially positioned and limited in the lateral direction, preventing displacement during assembly. Then, the operator rotates the threaded rod 1 on one side of the inner side of one chassis structure frame 2, gradually screwing it into the corresponding connection position inside the adjacent chassis structure frame 2. Utilizing the threaded connection of the threaded rod 1, the two chassis structures are firmly spliced ​​together. Following the same operation, more chassis structures can be spliced ​​sequentially to form a large chassis structure that meets the load-bearing requirements of longer car bodies. This splicing method is simple to operate and reliable in connection, breaking the limitations of a single chassis structure's application scenario and enabling it to adapt to the load-bearing requirements of car bodies of different lengths, significantly increasing the range of applications for the device.

[0038] Working principle: When assembling multiple devices, workers first align the corresponding ends of adjacent frame bodies 2, then slip the fixing ring 3 of one frame body 2 onto the limiting rod 6 of the other frame body 2. The interlocking relationship between the fixing ring 3 and the limiting rod 6 completes the initial positioning, preventing lateral displacement during assembly. Then, the threaded rod 1 on the side of the frame body 2 is rotated, causing it to screw into the preset connection position of the adjacent frame body 2. The threaded engagement forms a stable connection, achieving rigid assembly of multiple underframe structures. By repeating this operation, a longer underframe system can be formed to meet the load-bearing requirements of vehicles of different lengths, effectively expanding the applicable scenarios of the device and improving the flexibility and adaptability of the structure.

[0039] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
