Description

Technical Field

[0001] This utility model relates to the field of railway locomotive technology, and more specifically, to a railway locomotive maintenance anti-runaway device. Background Technology

[0002] A railway locomotive, commonly known as a "locomotive," is a power car that runs on a railway line and does not carry a commercial load (i.e., it does not carry passengers or cargo). It is specifically used to traction or push railway vehicles (such as passenger cars and freight cars). Simply put, its core task is to provide traction power, rather than directly transporting passengers or goods. The anti-runaway device for railway locomotive maintenance refers to a special safety device used to prevent locomotives from moving unexpectedly due to gravity or external forces when they are being repaired, maintained, or temporarily parked on maintenance lines with slopes (such as maintenance pits, parking lines, and drop lines). Its fundamental purpose is to create an absolutely safe and stationary working environment for maintenance personnel. It is a crucial safety device in railway locomotive depots and maintenance workshops.

[0003] For existing anti-runaway devices used in railway locomotive maintenance, if they have buffering capabilities, they can greatly reduce the impact damage to locomotives and tracks. Rigid braking may have uncertainties. Under extremely fast impacts, wheels may climb up the slope of the anti-runaway device and then roll back due to inertia, leading to braking failure. The buffer structure provides a continuously increasing damping force. Once the device starts to work, the resistance will increase steadily, making the wheels "gently but firmly" lock up, greatly improving the reliability and success rate of braking and avoiding failure caused by impact rebound.

[0004] In view of this, this paper studies and improves upon existing problems, and provides a railway locomotive maintenance anti-runaway device, aiming to solve the problem and improve its practical value through this technology. Utility Model Content

[0005] The purpose of this utility model is to provide a railway locomotive maintenance anti-runaway device to solve the problem and shortcomings of the existing railway locomotive maintenance anti-runaway devices mentioned in the background art, which cannot provide good buffering during use.

[0006] To achieve the above objectives, this utility model provides a railway locomotive anti-runaway device for maintenance, which is achieved by the following specific technical means:

[0007] A railway locomotive anti-slippage device for maintenance includes: a main body, a rail, a support plate, a buffer block, a support rod, a spring, a curved plate, a reinforcing rod, a limiting strip, a limiting block, a clamping plate, a screw, and a groove; the rail is attached to the lower inner wall of the main body, the support plate is fixedly connected to the inner wall of the main body, the buffer block is attached to the top of the support plate, and the outer wall of the buffer block is attached to the inner wall of the main body; the support rod is inserted into the inner wall of the buffer block, and a spring is sleeved on the outer wall of the support rod, with one end of the spring fixedly connected to the outer wall of the buffer block; one end of the support rod is fixedly connected to a curved plate fixedly connected to the outer wall of the main body, and the other end of the spring is fixedly connected to the outer wall of the curved plate.

[0008] As a further optimization of this technical solution, the outer wall of the curved plate of the anti-runaway device for railway locomotive maintenance of this utility model is fixedly connected with a reinforcing rod, and the outer wall of the reinforcing rod is fixedly connected to the outer wall of the main body.

[0009] As a further optimization of this technical solution, the top of the support plate and one side of the buffer block of the anti-runaway device for railway locomotive maintenance of this utility model are both arc-shaped structures.

[0010] As a further optimization of this technical solution, the main body of the anti-runaway device for railway locomotive maintenance of this utility model is threaded with screws on both sides below, and the ends of the two screws are rotatably connected to clamps through bearings, and the outer walls of the two clamps are tightly abutted against the outer wall of the track.

[0011] As a further optimization of this technical solution, in the anti-runaway device for railway locomotive maintenance of this utility model, the outer walls of the two clamping plates are fixedly connected to two limiting blocks, and the outer walls of multiple limiting blocks are in contact with the inner wall of the main body. The outer wall of the track is processed with multiple grooves, and the outer walls of the two clamping plates are engaged with some of the grooves.

[0012] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0013] 1. The main body, support plate, buffer block, support rod, spring, and curved plate of this utility model can provide buffering during use, thereby avoiding damage to locomotives and tracks caused by strong rigid collisions. At the same time, it can achieve smoother and more reliable braking. During braking, it provides a continuously increasing damping force. Once the device starts to work, the resistance will increase steadily, so that the wheels are locked in a "soft but firm" manner, which greatly improves the reliability and success rate of braking and avoids failure caused by impact rebound.

[0014] 2. The design of the main body, track, clamping plate, groove, screw, and limiting block of this utility model allows for quick installation and disassembly during use, thereby improving maintenance efficiency. Furthermore, the clamping plate and groove work together to firmly restrain the main body on the track, preventing accidental slippage and thus further enhancing safety.

[0015] 3. This utility model improves the anti-runaway device for railway locomotive maintenance, which has the advantages of being able to perform buffering treatment, and being able to be quickly installed and disassembled and ensure stable use, thus effectively solving the problems and shortcomings of existing devices.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] Please see Figures 1 to 4 This utility model provides a specific technical implementation scheme for an anti-runaway device for railway locomotive maintenance:

[0027] A railway locomotive anti-slippage device for maintenance includes: a main body 1, a rail 2, a support plate 3, a buffer block 4, a support rod 5, a spring 6, a curved plate 7, a reinforcing rod 8, a limiting strip 9, a limiting block 10, a clamping plate 11, a screw 12, and a groove 13; the rail 2 is attached to the lower inner wall of the main body 1, the support plate 3 is fixedly connected to the inner wall of the main body 1, the buffer block 4 is attached to the top of the support plate 3, and the outer wall of the buffer block 4 is attached to the inner wall of the main body 1; the support rod 5 is inserted into the inner wall of the buffer block 4, and the spring 6 is sleeved on the outer wall of the support rod 5; one end of the spring 6 is fixedly connected to the outer wall of the buffer block 4; one end of the support rod 5 is fixedly connected to the curved plate 7, which is fixedly connected to the outer wall of the main body 1, and the other end of the spring 6 is fixedly connected to the curved plate 7. The outer wall of plate 7 is fixedly connected; the elastic coefficient of spring 6 is not limited and can be selected according to the actual use. It should be noted that when using it, a damper structure should be set up to cooperate with spring 6, so as to consume the elastic potential energy of spring 6 and make spring 6 stabilize quickly. The type, installation method and installation position of the damper are not limited. It can be installed between curved plate 7 and buffer block 4, so as to consume the elastic potential energy of spring 6 when spring 6 deforms and make spring 6 stabilize quickly. Those skilled in the art should understand this in a broad sense, and this solution is not limited here.

[0028] A reinforcing rod 8 is fixedly connected to the outer wall of the curved plate 7, and the outer wall of the reinforcing rod 8 is fixedly connected to the outer wall of the main body 1; the reinforcing rod 8 can improve the strength of the curved plate 7.

[0029] The top of the support plate 3 and one side of the buffer block 4 are both arc-shaped; the arc-shaped design can increase the contact area with the wheel to improve the quality of use.

[0030] Both sides of the main body 1 are threaded with screws 12. The ends of the two screws 12 are rotatably connected to clamps 11 through bearings. The outer walls of the two clamps 11 are pressed against the outer wall of the track 2. The screws 12 can adjust the position of the clamps 11, and then the main body 1 is installed on the track 2 through the clamps 11.

[0031] Two limiting blocks 10 are fixedly connected to the outer walls of the two clamping plates 11, and the outer walls of multiple limiting blocks 10 are in contact with the inner wall of the main body 1. Multiple grooves 13 are machined on the outer wall of the track 2, and the outer walls of the two clamping plates 11 are engaged with some of the grooves 13. The limiting blocks 10 can limit the lowering of the clamping plates 11, and the cooperation between the clamping plates 11 and the grooves 13 can improve the connection strength when the main body 1 is installed on the track 2.

[0032] Specifically, it should be noted that staff need to maintain and replace spring 6 regularly to prevent it from aging and affecting its quality after prolonged use. There is no limit to the specific maintenance and replacement cycle; it can be determined according to the actual usage situation to meet the actual needs.

[0033] Specific implementation steps:

[0034] When in use, the operator places the main body 1 on the track 2 and then twists the screw 12. The screw 12 can drive the clamping plate 11 to move. At the same time, the limiting block 10 moves along the inner wall of the main body 1. When the protrusion of the clamping plate 11 is inserted into the groove 13, the outer wall of the clamping plate 11 is pressed against the outer wall of the track 2. At this time, the installation work is completed. When in use, when the wheel contacts the outer wall of the buffer block 4, the buffer block 4 can move along the inner wall of the main body 1 and the outer wall of the support rod 5, and compress the spring 6. The spring 6 provides buffer protection. At the same time, with the help of the external damper structure, the elastic potential energy of the spring 6 is consumed, so that the spring 6 can quickly stabilize and complete the work.

[0035] In summary, this anti-slippage device for railway locomotive maintenance, through the arrangement of a main body, support plate, buffer block, support rod, spring, and curved plate, can provide buffering during use, thereby avoiding damage to the locomotive and track caused by strong rigid collisions. It also achieves smoother and more reliable braking. During braking, it provides a continuously increasing damping force; once the device starts working, the resistance increases steadily, causing the wheels to be locked in a "gentle yet firm" manner, greatly improving the reliability and success rate of braking and preventing failure due to impact rebound. The arrangement of the main body, track, clamping plate, groove, screw, and limiting block allows for quick installation and disassembly during use, thus improving maintenance efficiency. Furthermore, the clamping plate and groove work together to firmly restrain the main body on the track, preventing accidental slippage and further improving safety. This utility model, through improvements to the anti-slippage device for railway locomotive maintenance, has the advantages of buffering, quick installation and disassembly, and guaranteed operational stability, effectively solving the problems and shortcomings of existing devices.
