[0015] In some embodiments, the limiting component includes:

[0016] A rotating block, one end of which is fixedly connected to the lifting assembly, and the other end of which can rotate relative to the vehicle frame. The rotating block has a working position and an adjustable position. In the working position, the other end of the rotating block is fixedly connected to the vehicle frame to limit the position of the lifting assembly.

[0017] In the adjusted position, the other end of the rotating block is separated from the frame so that the lifting assembly can adjust the height of the clamping wheel.

[0018] In some embodiments, the limiting component includes:

[0019] A positioning element is provided at the other end of the rotating block, and the positioning element is movable relative to the rotating block along the height direction of the vehicle frame;

[0020] The frame has a positioning groove. In the working position, the positioning member engages with the positioning groove; in the adjustment position, the positioning member separates from the positioning groove.

[0021] In some embodiments, the rotating block includes:

[0022] A connecting plate, which is fixedly connected to the lifting assembly;

[0023] An annular component, wherein the annular component has an inner cavity, and the positioning component passes through the inner cavity;

This enables adaptive adaptation to various track conditions, enhancing the applicability of the railway maintenance equipment.

[0037] Therefore, the railway maintenance equipment of this utility model has the advantages of compact structure, flexible adjustment and adaptability to various rail types. Attached Figure Description

[0050] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0051] like Figures 1 to 4 As shown, the railway maintenance equipment 100 of this utility model embodiment includes a frame 1, two traveling wheels 2, two clamping wheels 3, a lifting assembly 4, and a limiting assembly 5.

[0052] The frame 1 is equipped with maintenance components for maintenance operations.

[0053] Two wheels 2 are respectively located at both ends of the frame 1 along its length.

[0054] Two clamping wheels 3 are respectively located on both sides of the width direction of the frame 1, and the clamping wheels 3 are inclined so as to fit against the lower jaw of the rail.

[0055] The lifting assembly 4 is connected to the frame 1 and is used to adjust the height of the clamping wheel 3.

[0056] The limiting component 5 and the lifting component 4 are spaced apart, and the limiting component 5 is used to limit the position of the lifting component 4.

[0057] For ease of description, the technical solution of this application will be described below with the left-right direction as the width direction of the frame 1, the front-rear direction as the length direction of the frame 1, and the up-down direction as the height direction of the frame 1. Each direction is as follows: Figure 1 As shown.

[0058] Two traveling wheels 2 are respectively installed at the front and rear ends of the frame 1 to support the smooth movement of the entire railway maintenance equipment 100 along the front and rear direction of the rails.

[0059] Two clamping wheels 3 are respectively arranged on the left and right sides of the frame 1, and the clamping wheels 3 are set at an angle so that they can better fit the lower jaw of the rail head, enhance the clamping stability, and prevent the railway maintenance equipment 100 from shaking or shifting during operation.

[0060] The lifting assembly 4 is connected to the frame 1. Its main function is to adjust its own height to drive the clamping wheel 3 to move up and down, so as to adapt to rails of different rail types or wear levels, and ensure that the clamping wheel 3 can always fit tightly against the lower jaw of the rail, thereby improving the stability and operational safety of the railway maintenance equipment 100 on the monorail.

[0061] The limiting component 5 and the lifting component 4 are spaced apart to limit the vertical movement of the lifting component 4, preventing structural instability or damage caused by excessive lifting, thereby ensuring the reliability and controllability of the railway maintenance equipment 100 during the adjustment process.

[0062] In related technologies, the chassis of railway maintenance equipment is typically designed to run on double tracks. While this structure ensures the stability of the equipment to a certain extent, the requirement to straddle two rails results in a large size and complex structure for the entire maintenance equipment. At construction sites, such equipment not only occupies a lot of space, but also easily interferes when two pieces of equipment pass each other on the tracks, affecting construction efficiency.

[0063] The railway maintenance equipment 100 of this utility model adopts a single-rail walking mode, which makes the equipment smaller, more compact and flexible. When two devices meet on the rails, each device can move smoothly on its own single rail, thereby avoiding mutual interference and improving construction efficiency.

[0064] Furthermore, under long-term harsh conditions, the friction between train wheels and rails causes wavy wear on the top surface of the rails due to high-frequency friction, while the sides develop thick edges or peeling due to stress concentration from wheel-rail contact. In the railway maintenance equipment 100 of this utility model embodiment, the clamping wheel 3 is inclined, allowing it to better fit the lower jaw structure of the rail head, providing a more stable and reliable clamping force during monorail operation, effectively preventing equipment swaying or deviation, thereby improving overall operational stability and safety. The lifting component 4 makes the height of the clamping wheel 3 adjustable, allowing for flexible adjustments according to different rail types or rail wear levels, achieving adaptive adaptation to various track conditions, and enhancing the applicability of the railway maintenance equipment 100.

[0065] Therefore, the railway maintenance equipment 100 of this utility model embodiment has the advantages of compact structure, flexible adjustment and adaptability to various rail types.

[0066] like Figure 3 As shown, in some embodiments, the lifting assembly 4 includes a lifting rod 41 and an adjusting nut 42. The lifting rod 41 is movable along the height direction of the frame 1, and the bottom of the lifting rod 41 is connected to the clamping wheel 3. The adjusting nut 42 is threadedly connected to the lifting rod 41.

[0067] The lifting rod 41 is movable in the vertical direction, and its bottom is connected to the clamping wheel 3. The adjusting nut 42 is threadedly connected to the lifting rod 41; rotating the adjusting nut 42 precisely controls the vertical movement of the lifting rod 41, thereby flexibly adjusting the height of the clamping wheel 3 to accommodate various rail types. Therefore, the railway maintenance equipment 100 of this embodiment has a simple structure and is easy to adjust.

[0068] In some embodiments, the frame 1 is provided with a mounting groove 11, the lifting rod 41 passes through the mounting groove 11, and the bottom of the adjusting nut 42 is provided with a stop plate 421.

[0069] The lifting assembly 4 includes a first elastic element 43, which is disposed in the mounting groove 11 and sleeved on the lifting rod 41. One end of the first elastic element 43 abuts against the bottom wall of the mounting groove 11, and the other end of the first elastic element 43 abuts against the stop plate 421.

[0070] The first elastic element 43 is disposed in the mounting groove 11 and sleeved on the lifting rod 41. Its bottom end abuts against the bottom wall of the mounting groove 11, and its top end abuts against the stop plate 421.

[0071] The first elastic element 43 exerts a force that causes the stop plate 421 to move upward, thereby driving the adjusting nut 42 and the lifting rod 41 to move upward as a whole, further driving the clamping wheel 3 to press against the lower jaw of the rail, ensuring close contact and stable clamping between the clamping wheel 3 and the rail. Moreover, the first elastic element 43 can also absorb vibration and impact, playing a shock absorption role.

[0072] The railway maintenance equipment 100 of this utility model not only realizes the adaptive adjustment of the clamping wheel 3 to different rail types, improving the stability and safety of the railway maintenance equipment 100 during monorail operation, but also effectively absorbs vibration and impact during operation through elastic buffering.

[0073] In some embodiments, such as Figure 2 As shown, the limiting component 5 includes a rotating block 51. One end of the rotating block 51 is fixedly connected to the lifting component 4, and the other end of the rotating block 51 can rotate relative to the frame 1. The rotating block 51 has a working position and an adjusting position. In the working position, the other end of the rotating block 51 is fixedly connected to the frame 1 to limit the position of the lifting component 4.

[0074] In the adjustment position, the other end of the rotating block 51 is separated from the frame 1 so that the lifting assembly 4 can adjust the height of the clamping wheel 3.

[0075] One end of the rotating block 51 is fixedly connected to the lifting assembly 4. For example, the rotating block 51 is fixedly connected to the top of the lifting rod 41 through a threaded hole and a threaded post.

[0076] The other end of the rotating block 51 can rotate relative to the frame 1.

[0077] When the rotating block 51 is in the working position, one end of the rotating block 51 is fixedly connected to the lifting assembly 4, and the other end of the rotating block 51 is fixedly connected to the frame 1. This fixed connection effectively restricts the position of the lifting assembly 4, ensuring that the clamping wheel 3 remains stable during operation and will not move unnecessarily due to external forces, thereby improving the safety and stability of the railway maintenance equipment 100. When adjusting the position, the other end of the rotating block 51 separates from the frame 1, allowing the lifting assembly 4 to freely adjust the height of the clamping wheel 3 to adapt to different rail types.

[0078] When the height of the clamping wheel 3 needs to be adjusted, the operator simply switches the rotating block 51 to the adjustment position, releases its fixed connection with the frame 1, and then controls the up-and-down movement of the lifting rod 41 by adjusting the nut 42 to precisely adjust the position of the clamping wheel 3. After adjustment, the rotating block 51 is rotated back to the working position and reconnected to the frame 1 to ensure that the railway maintenance equipment 100 returns to a stable working state. This design not only ensures the adaptability of the railway maintenance equipment 100 under complex working conditions but also enhances the ease of operation.

[0079] In some embodiments, such as Figure 2 and Figure 4 As shown, the limiting component 5 includes a positioning member 52, which is located at the other end of the rotating block 51, and the positioning member 52 can move relative to the rotating block 51 along the height direction of the frame 1.

[0080] The frame 1 has a positioning groove 12. In the working position, the positioning member 52 engages with the positioning groove 12. In the adjustment position, the positioning member 52 separates from the positioning groove 12.

[0081] The positioning element 52 is located at the other end of the rotating block 51 and can move relative to the rotating block 51 in the vertical direction.

[0082] The frame 1 is provided with a positioning groove 12. The positioning component 52 and the positioning groove 12 are used to fix the position of the rotating block 51, so as to ensure that the lifting assembly 4 and its connected clamping wheel 3 remain stable during operation.

[0083] Specifically, when in the working position, the positioning component 52 cooperates with the positioning groove 12 on the frame 1, so that one end of the rotating block 51 is fixedly connected to the lifting component 4, while the other end is locked on the frame 1 by the positioning component 52, thereby effectively restricting the position of the lifting component 4 and ensuring the safety and stability of the railway maintenance equipment 100 operation.

[0084] When adjusting the position, the positioning component 52 separates from the positioning groove 12, allowing the other end of the rotating block 51 to disengage from the frame 1. This allows the height of the lifting assembly 4 to be freely adjusted to accommodate different rail types or rail wear levels.

[0085] The railway maintenance equipment 100 of this utility model embodiment, through the cooperation of the positioning component 52 and the positioning groove 12, ensures that the locking state can be easily released when the clamping wheel 3 needs to be adjusted, and can quickly return to a stable working state after the adjustment is completed, thus facilitating adjustment.

[0086] In some embodiments, the rotating block 51 includes a connecting plate 511 and an annular member 512, the connecting plate 511 being fixedly connected to the lifting assembly 4. The annular member 512 has an inner cavity 5121, and the positioning member 52 passes through the inner cavity 5121.

[0087] The limiting component 5 includes a second elastic member 53, which is disposed in the inner cavity 5121 and sleeved on the outer periphery of the positioning member 52. The positioning member 52 is provided with a first stop portion 520. One end of the second elastic member 53 abuts against the first stop portion 520, and the other end of the second elastic member 53 abuts against the top wall of the inner cavity 5121.

[0088] The rotating block 51 includes a connecting plate 511 and an annular component 512. The connecting plate 511 is fixedly connected to the lifting assembly 4 to ensure that the rotating block 51 can move together with the lifting assembly 4 and to provide stable support.

[0089] The annular member 512 has an inner cavity 5121 with its opening facing downwards, and the positioning member 52 passes through the inner cavity 5121. In addition, the limiting assembly 5 also includes a second elastic member 53 (e.g., a spring), which is disposed in the inner cavity 5121 of the annular member 512 and sleeved on the outer periphery of the positioning member 52.

[0090] One end of the second elastic element 53 abuts against the first stop portion 520, and the other end abuts against the top wall of the inner cavity 5121. The second elastic element 53 has a force that causes the first stop portion 520 to move downward. When the rotating block 51 is in the working position, the elastic force provided by the second elastic element 53 will push the positioning element 52 downward, so that its end is accurately inserted into the positioning groove 12 on the frame 1, realizing a firm connection between the rotating block 51 and the frame 1. This not only restricts the position of the lifting assembly 4, but also enhances the overall stability and safety of the railway maintenance equipment 100 during operation.

[0091] In some embodiments, the positioning member 52 includes a handle 521 and a positioning rod 522. The handle 521 is provided with a first locking part, the positioning rod 522 is engaged with or separated from the positioning groove 12, the handle 521 is located on the top of the positioning rod 522, and the positioning rod 522 is provided with a second locking part. The first locking part and the second locking part are locked together.

[0092] The handle 521 is designed to facilitate manual operation of the positioning element 52 by the operator. When it is necessary to remove the positioning element 52 from the positioning groove 12 to adjust the height of the clamping wheel 3, the operator can apply an upward force by pulling the handle 521 to overcome the elastic force of the second elastic element 53, so that the positioning rod 522 is disengaged from the positioning groove 12.

[0093] When the positioning rod 522 is inserted into the positioning slot 12, the rotating block 51 is fixed, restricting the position of the lifting assembly 4; when the positioning rod 522 is pulled out of the positioning slot 12, the rotating block 51 is in a free state, allowing the lifting assembly 4 to adjust its height.

[0094] The design of the first and second locking parts ensures a secure connection between the handle 521 and the positioning rod 522, while also facilitating their assembly and disassembly.

[0095] The railway maintenance equipment 100 of this utility model allows operators to manipulate the positioning rod 522 via the handle 521, quickly aligning or separating the positioning rod 522 from the positioning groove 12 to adapt to different rail types. Furthermore, the first and second locking parts enhance the connection strength between the handle 521 and the positioning rod 522, ensuring that loosening or failure does not occur during frequent operations.

[0096] Optionally, the top of the annular part 512 is provided with a through hole, the top end of the positioning rod 522 fits into the through hole, and the diameter of the handle 521 is larger than the diameter of the through hole, thereby forming a stepped surface at the bottom of the handle 521. The stepped surface abuts against the top surface of the annular part 512, thereby playing a limiting role and preventing the positioning rod 522 from coming out of the annular part 512.

[0097] In some embodiments, the lifting assembly 4 includes a connecting shaft 44, one end of which is fixedly connected to the lifting rod 41, and the other end of which is provided with a clamping wheel 3. The other end of the connecting shaft 44 is lower than one end of the connecting shaft 44 so that the clamping wheel 3 is tilted.

[0098] One end of the connecting shaft 44 is fixedly connected to the lifting rod 41, and the other end is provided with a clamping wheel 3, which can rotate relative to the connecting shaft 44.

[0099] The connecting shaft 44 is inclined, so that the clamping wheel 3 is in an inclined state after installation. This inclined setting can better adapt to the contour shape of the rail head, so that the clamping wheel 3 and the lower jaw of the rail form a tighter and more intimate contact surface, thereby improving the clamping stability and anti-slip ability during operation.

[0100] In some embodiments, the frame 1 includes a frame 13 and two connecting seats 14, the frame 13 being connected to the wheels 2.

[0101] Two connecting seats 14 are respectively provided on both sides of the frame 13 in the width direction of the frame 1. The lifting component 4 and the limiting component 5 are both provided on the connecting seats 14.

[0102] The frame 13 is used to connect with the traveling wheels 2 to enable the entire device to move back and forth along the rails.

[0103] Two connecting seats 14 are respectively set on the left and right sides of the frame 13 and arranged symmetrically. The lifting component 4 and the limiting component 5 are both installed on the connecting seats 14, so that each functional component can be stably integrated on the frame 1 structure, which not only ensures the compactness of the overall structure, but also facilitates assembly and maintenance.

[0104] Optionally, the connecting seat 14 is provided with a clearance groove, and the positioning groove 12 is provided on the bottom surface of the clearance groove. The cross-sectional area of ​​the clearance groove is larger than the cross-sectional area of ​​the annular part 512, thereby providing sufficient space for the movement of the annular part 512, ensuring that the annular part 512 and the positioning part 52 can move up and down with the lifting rod 41 within a certain range without obstruction.

[0105] In some embodiments, the traveling wheel 2 includes a traveling part 21 and two limiting parts 22. The traveling part 21 is disposed between the two limiting parts 22, and the diameter of the traveling part 21 is smaller than the diameter of the limiting parts 22.

[0106] The traveling section 21 is the part where the traveling wheel 2 directly contacts the top surface of the rail. Two limiting sections 22 are located on both sides of the traveling section 21. They have a large diameter and their main function is to provide lateral restraint to prevent the traveling wheel 2 from derailing from the rail.

[0107] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
