Description

Technical Field

[0001] The utility model relates to the field of tooling equipment and provides a wheelset tread lifting device. Background Art

[0002] The bogie completion process is responsible for the connection and assembly of the bogie wheelset and the frame, which connects the parts into a whole. During the team operation, it is necessary to assemble the coupling and measure the diagonal dimensions, and fix the wheelset. Due to the different wheelbases of EMUs and urban rail EMUs, it is necessary to continuously switch the wheelset fixing tooling. This has a great impact on the operation method.

[0003] 1. The wheelbase of the EMU is 2500mm, and the wheelbase of the urban rail is 2400 and 2300mm. When the team performs assembly operations, it is necessary to repeatedly disassemble, assemble, and move the wheel set fixing devices, resulting in personnel, efficiency, and cost losses.

[0004] 2. When the bogie is hoisted from the completion position to the adjustment position, since the supporting device is on the inner side of the wheelset, the wheel cake and the device may resist each other when the frame falls, causing the bogie to tilt and the wheel rim to bump against each other. At the same time, it may cause the tooling to bend, resulting in multiple repairs of the tooling.

[0005] 3. When measuring the diagonal of the bogie, it is necessary to repeatedly rotate the tooling to fix the wheelset twice for measurement, which is inefficient.

[0006] 4. During the coupling assembly operation, in order to ensure that the wheelset does not move when tightening the coupling, the wheelset needs to be fixed. The wheelset needs to be fixed repeatedly 12 times, which is inefficient. The movement of the wheelset when tightening the coupling can easily lead to the failure of the coupling bolts and the failure to properly engrave the torque. Utility Model Content

DETAILED DESCRIPTION

[0039] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0040] like Figures 1 to 4 As shown, the embodiment of the utility model provides a wheelset tread lifting device, comprising:

[0041] Base 100;

[0042] A sliding seat 102 slidably connected to the base 100;

[0043] A support rod 104 is escalably mounted on the sliding seat 102 and is adapted to unlock or lock the relative position of the support rod 104 with the sliding seat 102 through a lifting control assembly;

[0044] The tread support assembly 106 is disposed at one end of the support rod 104 away from the sliding seat 102 , and the tread support assembly 106 is used to support the wheelset tread.

[0045] According to the wheelset tread lifting device provided by the embodiment of the utility model, the sliding seat 102 and the base 100 are connected in a slidable manner, so that the entire device can move smoothly and stably along the base 100 during use, adapting to the needs of different workstations or flexibly adjusting according to the specific position of the wheelset. At the same time, the liftable installation design between the support rod 104 and the sliding seat 102 makes the height of the tread support assembly 106 adjustable, which is convenient for accurate positioning and contact of the wheelset treads at different heights, ensuring stability and safety during the lifting process. By setting the lifting control assembly, the operator can easily and quickly unlock or lock the relative position between the support rod 104 and the sliding seat 102 to achieve the lifting action of the tread support assembly 106. This design simplifies the operation process of the lifting process, improves work efficiency, and avoids equipment damage or personnel safety hazards caused by manual forced adjustment. The tread support assembly 106 is specially designed for the wheelset tread, and its structure and material take into account factors such as effective contact with the tread, stable load bearing and damage prevention, and can provide reliable support for the wheelset tread in a targeted manner. Regardless of the different specifications and types of wheelsets, the device can ensure good adaptability and meet the needs of wheelset maintenance, replacement or storage in various application scenarios. The base 100 serves as the basic support of the entire device, ensuring the stability of the overall structure; the coordinated design of the sliding seat 102 and the support rod 104 realizes the effective use of space, making the overall layout of the device compact, which is not only conducive to flexible arrangement in a limited working area, but also enhances the anti-overturning ability of the equipment during operation, further improving the safety factor of the operation. Compared with the traditional manual or simple tool lifting of wheelsets, the wheelset tread lifting device of the utility model greatly reduces the physical exertion of the operator, avoids the problems of lifting difficulties or instability caused by insufficient manpower, and significantly improves the efficiency of wheelset handling work, which is conducive to optimizing the production process and reducing operating costs.

[0046] Please continue to see Figures 1 to 4 In the embodiment of the utility model, the base 100 serves as the basic support part of the entire device. The base 100 is made of a sturdy and durable material and has sufficient load-bearing capacity and stability to ensure that there is no shaking or tilting during the lifting of the wheelset. The base 100 is generally designed as a rectangular or square structure, with a non-slip foot pad or fixing hole at the bottom to facilitate the stable placement and fixing of the device.

[0047] The sliding seat 102 and the base 100 are connected slidably by using precise slide rails 134 or ball bearings, etc., to ensure that the sliding seat 102 can move smoothly forward and backward or left and right on the base 100. The sliding range of the sliding seat 102 can be set according to actual work requirements to adapt to wheelsets in different positions or to be flexibly arranged in a limited space. The sliding seat 102 is provided with a locking device (such as a stop bolt or a clamping handle), and when the position of the sliding seat 102 needs to be fixed, the sliding seat 102 can be firmly locked at a specified position on the base 100 through the device.

[0048] The design of the sliding seat 102 enables it to move flexibly on the base 100, so as to quickly locate the position of the wheelset to be lifted, greatly improving work efficiency. The setting of the lifting control component makes it easy to adjust the height of the support rod 104, without heavy manual operation, and adapts to the operation requirements of wheelsets of various heights.

[0049] The support rod 104 is a high-strength metal component, one end of which is connected to the sliding seat 102 through a hydraulic cylinder, a pneumatic cylinder, a screw nut mechanism or other lifting drive device to achieve the lifting function. The lifting action of the support rod 104 is controlled by a matching control system (such as an electric control panel, a remote control or a manual valve) through a lifting control component. The lifting control component can unlock or lock the relative position of the support rod 104 and the sliding seat 102. When unlocked, the operator can easily adjust the height of the support rod 104; when locked, the support rod 104 remains at the set height to ensure stability during the lifting process.

[0050] The locking mechanism between the support rod 104 and the sliding seat 102 ensures that the support rod 104 will not drop accidentally during the lifting process, thereby ensuring the stability of the equipment operation. The stable design of the base 100 and the locking device of the sliding seat 102 together enhance the anti-overturning ability of the entire device and ensure the safety of the operator.

[0051] The tread support assembly 106 is installed at the end of the support rod 104 away from the sliding seat 102. It is a key component that directly contacts the wheelset tread and provides support. Its design fully considers the shape, hardness and force characteristics of the wheelset tread. It is usually made of wear-resistant and pressure-resistant materials (such as cemented carbide, high-strength steel or special rubber), and is finely processed to ensure a good fit with the tread. The tread support assembly 106 may include but is not limited to: a support plate with fine-tunable angle or position, a flexible contact pad, anti-slip grooves or embedded sensors (for detecting contact pressure or displacement). These designs are intended to ensure that during the lifting process, it can provide stable support and effectively protect the wheelset tread from damage.

[0052] The tread support assembly 106 is specially designed for the characteristics of the wheelset tread, and can accurately and evenly bear the weight of the wheelset to avoid tread damage caused by local overload. The selected wear-resistant and pressure-resistant materials and the fine-tuning and anti-skid functional designs further enhance the protection effect of the wheelset tread.

[0053] In summary, the wheelset tread lifting device provided in the embodiment of the utility model replaces traditional manual lifting with mechanized and automated means, which significantly reduces the physical burden of operators, improves the wheelset processing speed, helps to optimize the production process and reduce operating costs.

[0054] According to an embodiment of the present invention, a sleeve 108 is disposed on the sliding seat 102 , and the support rod 104 is installed on the sleeve 108 in a liftable manner.

[0055] like Figure 1 As shown, in the embodiment of the utility model, the sleeve 108 is integrated on the sliding seat 102 as a receiving and guiding component of the support rod 104, so that the lifting and lowering movement of the support rod 104 is more orderly and compact. Such a design reduces additional connecting parts, optimizes the overall layout of the device, improves space utilization, and is particularly suitable for small or restricted working environments.

[0056] The sleeve 108 usually has a smooth inner wall, which can provide precise linear guidance for the support rod 104, prevent the support rod 104 from deflecting or shaking during the lifting process, and ensure the stability and verticality of the movement of the support rod 104. This is crucial for the precise positioning of the wheelset tread and maintaining stability during the lifting process.

[0057] In addition, wear-resistant materials or wear-resistant bushings are usually used between the sleeve 108 and the support rod 104 to reduce friction loss between the two. This design not only ensures low damping and high efficiency during the lifting process of the support rod 104, but also effectively extends the service life of the sleeve 108 and the support rod 104, reducing the maintenance cost of the equipment.

[0058] In some embodiments, a sealing element (such as a sealing ring, a sealing gasket, etc.) may be configured between the sleeve 108 and the support rod 104 to prevent dust, impurities or liquids from entering the connection between the sliding seat 102 and the support rod 104, thereby protecting internal components from contamination and ensuring the normal operation and long-term reliability of the device.

[0059] The sleeve 108 structure makes the installation and disassembly of the support rod 104 easier. When the support rod 104 or the lifting drive device associated therewith needs to be inspected, repaired or replaced, it is only necessary to operate through the sleeve 108 without large-scale disassembly of the sliding seat 102, which greatly simplifies the maintenance work of the equipment and shortens the downtime.

[0060] According to an embodiment of the present invention, the support rod 104 and the sleeve 108 are threadedly connected and a rotating rod 110 is sleeved on the support rod 104 .

[0061] like Figure 1 and Figure 3 As shown, in the embodiment of the utility model, the threaded connection between the support rod 104 and the sleeve 108 allows the operator to achieve the lifting and lowering of the support rod 104 in the sleeve 108 by rotating the support rod 104. This method does not require a complex power system or electronic control equipment, and the height of the support rod 104 can be easily adjusted by manually rotating the rotating rod 110. The operation is simple and convenient, and is particularly suitable for occasions without power supply or requiring a quick response.

[0062] The threaded connection also has a certain self-locking property. Once the support rod 104 stops rotating, its height will remain unchanged without the need for an additional locking device. This self-locking function ensures that during the lifting process, even if there is interference from external forces, the support rod 104 can remain in the set position to avoid accidental slipping, greatly improving the safety of the device. The threaded connection also allows for fine-grained height adjustment of the support rod 104, which is particularly suitable for scenarios that require precise lifting height. The operator can gradually rotate the rotating rod 110 according to actual conditions to fine-tune the height of the support rod 104, ensure that the tread support assembly 106 is accurately aligned with the wheelset tread, and adapt to wheelsets of different models and sizes, thereby enhancing the versatility and adaptability of the device.

[0063] The rotating rod 110 is sleeved on the support rod 104, which provides a force point for the operator, effectively increases the force arm, and makes it easier to rotate the support rod 104. Especially when supporting a heavier wheel set, the operation through the rotating rod 110 can significantly reduce the operator's physical consumption and improve work efficiency.

[0064] According to one embodiment of the utility model, the lifting control assembly includes:

[0065] A first pedal 112, the first pedal 112 is hinged to the support rod 104, and the first pedal 112 is adapted to switch between a first unlocking position and a first locking position. In the first unlocking position, the support rod 104 is adapted to be lifted and lowered relative to the sleeve 108. In the first locking position, the support rod 104 is adapted to be locked relative to the sleeve 108;

[0066] The second pedal 114 is hinged to the support rod 104, and the second pedal 114 is suitable for switching between a second unlocked position and a second locked position. In the second unlocked position, the first pedal 112 is suitable for switching between a first unlocked position and a first locked position. In the second locked position, the second pedal 114 is suitable for limiting the first pedal 112 to be in the first locked position.

[0067] like Figures 1 to 3 As shown, in the embodiment of the utility model, the first pedal 112 and the second pedal 114 are respectively responsible for the primary unlocking and locking and the secondary locking of the support rod 104, forming a double insurance mechanism. When the first pedal 112 is in the first unlocking position, the support rod 104 can be raised and lowered freely; when the first pedal 112 is turned to the first locking position, the support rod 104 is initially locked; and when the second pedal 114 is in the second locking position, the possibility of the first pedal 112 returning to the unlocking position is further limited, ensuring the absolute fixation of the support rod 104. This double-layer protection design greatly improves the safety of the device and avoids the risk of unexpected lifting and lowering of the support rod 104 due to misoperation or unexpected circumstances.

[0068] The first pedal 112 and the second pedal 114 are both physical entities hinged to the support rod 104, and their unlocked and locked states are intuitively presented through obvious position changes of the pedals. Operators do not need professional knowledge, and can judge whether the support rod 104 is currently available for lifting or lowering by simply observing the position of the pedals, which greatly reduces the threshold for use and facilitates rapid training and correct operation.

[0069] The pedal design allows the operator to unlock and lock the door by simply stepping on it, without bending over or using tools, which reduces the intensity of the operation and improves work efficiency. This design has a particularly obvious advantage in operating scenarios where the height of the support rod 104 is frequently adjusted.

[0070] The existence of the second pedal 114, especially its function of limiting the first pedal 112 to the first locking position, effectively prevents the first pedal 112 from being accidentally triggered to the unlocking position when there is no need to raise or lower the support rod 104. This anti-accidental touch design enhances the stability of the device in the working state, avoids the sudden raising or lowering of the support rod 104 due to unintentional touch, and ensures the safety and stability of the operation process.

[0071] According to one embodiment of the utility model, a mounting plate 116 is provided at one end of the support rod 104 away from the sliding seat 102, and the tread support assembly 106 is hinged to the mounting plate 116. The relative angle between the tread support assembly 106 and the mounting plate 116 is suitable for adjusting the relative angle between the tread support assembly 106 and the mounting plate 116 through an angle adjustment assembly.

[0072] like Figure 1 and Figure 3 As shown, in the embodiment of the utility model, since the wheelset may have a certain inclination or deflection in actual application, the angle between the tread support assembly 106 and the mounting plate 116 is adjusted by the angle adjustment assembly, so that the tread support assembly 106 can maintain the best contact state with the wheelset tread, and can provide effective support regardless of the posture of the wheelset, thereby significantly enhancing the adaptability of the device.

[0073] The precise angle adjustment capability enables the tread support assembly 106 to evenly distribute the pressure on the wheelset tread, avoiding tread damage caused by local overload. Especially for precision machined treads, this design helps to maintain its original geometry and surface quality, extending the service life of the wheelset.

[0074] The tread support with proper angle can more effectively resist the lateral force, reduce the shaking of the wheelset during the lifting process, and improve the stability of the lifting process. This is especially important for wheelset operations at high places or in narrow spaces, and can effectively prevent safety accidents.

[0075] The setting of the angle adjustment assembly makes the connection between the tread support assembly 106 and the mounting plate 116 have a certain degree of mobility, which is conducive to absorbing vibration and reducing stress concentration, thereby reducing component wear and extending the service life of the equipment. At the same time, when the tread support assembly 106 needs to be maintained or replaced, the angle can be conveniently adjusted to facilitate operation, thereby improving maintenance convenience.

[0076] According to one embodiment of the utility model, the angle adjustment assembly includes:

[0077] An adjusting rod 118, a first end of the adjusting rod 118 is hinged to the mounting plate 116;

[0078] The slide groove 120 is opened on the side of the tread support assembly 106 facing the mounting plate 116. The second end of the adjustment rod 118 is slidably installed in the slide groove 120, and the second end of the adjustment rod 118 is suitable for locking the relative position with the slide groove 120 through a locking member.

[0079] like Figure 1 and Figure 3 As shown, in the embodiment of the present invention, the adjustment rod 118 is hinged to the mounting plate 116, and the second end thereof is slidable in the slide slot 120, so that the operator can change the relative angle between the tread support assembly 106 and the mounting plate 116 by moving the adjustment rod 118. The linear guiding effect of the slide slot 120 ensures the accuracy of the angle adjustment, so that the tread support assembly 106 can be accurately aligned with the wheelset tread, providing the best support effect.

[0080] The design of the adjustment rod 118 makes the angle adjustment process intuitive and simple, without the need for complex mechanical equipment or tools, and the angle adjustment can be completed by manually pushing or pulling the adjustment rod 118. This design reduces the difficulty of operation, saves adjustment time, and improves work efficiency.

[0081] The second end of the adjustment rod 118 is locked with the slide slot 120 by a locking member (such as a bolt, a clamp or a buckle, etc.), ensuring that the angle of the tread support assembly 106 remains constant during the lifting process and will not change due to external forces. This locking mechanism enhances the stability of the lifting process and ensures the safety of the operation.

[0082] The matching design of the adjustment rod 118 and the slide slot 120 integrates the angle adjustment function between the tread support assembly 106 and the mounting plate 116, does not occupy additional space, maintains the overall compactness of the device, and is conducive to operation in a limited space. When the tread support assembly 106 needs to be maintained or replaced, it is only necessary to loosen the locking member and move the adjustment rod 118 along the slide slot 120 to adjust the tread support assembly 106 to a position that is convenient for operation, thereby simplifying the maintenance process and reducing labor intensity.

[0083] According to one embodiment of the present invention, the tread support assembly 106 includes:

[0084] A connecting plate 122 is hinged to the mounting plate 116;

[0085] A guide column 124 is mounted on the connecting plate 122 and an elastic support member 126 is sleeved on the guide column 124;

[0086] The tread support plate 128 is installed on one end of the guide column 124 away from the connecting plate 122. The side of the tread support plate 128 away from the connecting plate 122 is adapted to the shape of the wheelset tread. The two ends of the elastic support member 126 respectively abut against the opposite sides of the connecting plate 122 and the tread support plate 128.

[0087] like Figure 1 and Figure 3 As shown, in the embodiment of the utility model, the side of the tread support plate 128 away from the connecting plate 122 is adapted to the shape of the wheelset tread, ensuring effective support for the tread. The setting of the elastic support member 126 enables the tread support plate 128 to provide a certain buffering effect when contacting the wheelset tread, reduce the impact force, avoid scratches or deformation of the tread caused by hard contact, and effectively protect the integrity of the wheelset tread. In addition, the elastic support member 126 can absorb the surface unevenness caused by manufacturing errors, wear or slight deformation of some wheelsets, so that the tread support plate 128 can better adapt to the actual conditions of different wheelset treads, and improve the adaptability of the device to different wheelsets. The elastic support member 126 will undergo elastic deformation when under pressure, dispersing the force concentrated at one point to a larger contact area, reducing the pressure per unit area, and improving the bearing capacity of the tread support assembly 106 for the weight of the wheelset, while also reducing the risk of fatigue damage of the support plate itself due to stress concentration.

[0088] Through the guide column 124, a relatively adjustable structure is formed between the tread support plate 128 and the connecting plate 122. When the elastic support member 126 needs to be replaced or adjusted, the operation can be performed more conveniently without the need to disassemble the tread support assembly 106 as a whole, thereby simplifying the maintenance process and reducing maintenance costs.

[0089] According to an embodiment of the present invention, a first hinge column 130 is disposed on the connecting plate 122 , and a second hinge column 132 is disposed on the mounting plate 116 . The first hinge column 130 and the second hinge column 132 are hinged to each other.

[0090] like Figure 1 As shown, in the embodiment of the utility model, the first hinge column 130 and the second hinge column 132 are hinged to enable the connecting plate 122 and the tread support assembly 106 thereon to swing at a certain angle relative to the mounting plate 116 to adapt to the inclination or deflection of different wheelset treads. This design greatly enhances the adaptability of the device to different wheelset postures and ensures effective contact and support between the tread support assembly 106 and the wheelset tread.

[0091] According to an embodiment of the present invention, a slide rail 134 is disposed on the base 100 , a slider 136 is disposed on the sliding seat 102 , and the slider 136 is slidably matched with the slide rail 134 ; and limit members are disposed at both ends of the slide rail 134 .

[0092] like Figure 2 As shown, in the embodiment of the utility model, the matching design of the slide rail 134 and the slider 136 makes the movement of the sliding seat 102 on the base 100 smoother and more stable, reduces the shaking or jamming caused by poor sliding, improves the stability of the wheelset during the lifting process, and is conducive to ensuring operation safety.

[0093] The limiter limits the sliding stroke of the sliding seat 102, effectively preventing the sliding seat 102 from accidentally sliding out of the slide rail 134 due to external force, avoiding the risk of equipment damage or personal injury, and significantly improving the safety of the device.
