BACKGROUND

[0002] The plummet limiting frame is one of the key components in the catenary system of electrified railways, which aims to limit the movement of the plummet string and a series of connecting components of the plummet within a certain range, to ensure the stability of the catenary and the safety of the train; under severe environmental conditions such as strong wind, the unrestricted swing of the plummet string may cause a series of problems, such as mutual collision, jamming, deflection, and even intrusion into the limit area, thereby endangering the normal operation of railway traffic, and the frame with a larger surface roughness in the plummet limiting frame can increase the friction between the frame and the plummet, effectively reducing the swing amplitude of the plummet string and improving its stability.

[0003] The existing limiting frame surface roughness processing device can process the surface of the frame, but due to the adoption of a two-way clamping method to fix the frame, the shape of the frame that can be processed by the device is limited, which limits the application range of the device; in addition, due to the small movable range of the position of the cutter of the existing processing device, the size of the frame that can be processed is limited, which requires multiple repeated start and stop, reducing the work efficiency. SUMMARY

[0008] The clamping assembly comprises a shell one, a shell two, a motor five, a transmission gear, a gear ring, a sliding rail three, a clamping block one, a guide groove, a limiting cylinder, a fixed cover, a clamping block two and a groove, the shell one is fixedly connected to the outer wall of the rotating cylinder, the shell two is fixedly connected to the outer wall of the shell one, the motor five is fixedly connected to the bottom outer wall of the shell one, the transmission gear is fixedly connected to the outer wall of the main shaft of the motor five, the gear ring is rotatably connected to the inner wall of the shell one, the sliding rail three is fixedly connected to the outer wall of the gear ring, the sliding rail three is annular and spiral in shape, providing a track for the sliding of the clamping block one, the clamping block one is slidably connected to the outer walls of the shell one and the sliding rail three, and a plurality of clamping block ones are arranged to achieve multidirectional clamping of the frame, the guide groove is formed in the outer wall of the clamping block one, the limiting cylinder is slidably connected to the inner wall of the shell one, the fixed cover is rotatably connected to the outer wall of the limiting cylinder, the clamping block two is fixedly connected to the inner wall of the fixed cover, and the groove is formed in the outer wall of the clamping block two.

[0009] Furthermore, an inner thread corresponding to the screw rod one is formed in the inner wall of the sliding plate one, the motor one drives the screw rod one to rotate, the sliding plate one drives the entire polishing assembly to slide left and right on the sliding rail one, and the polishing knife can be adjusted in a large range in the transverse direction, which means that the operator can adjust the position of the polishing knife according to the actual size of the frame, so as to cover a longer frame surface in one processing process.

[0010] Further, the grinding knife is driven by the motor three to rotate at high speed, and when it contacts with the surface of the frame to be processed, it forms friction with the surface, thereby improving the roughness of the surface of the frame. The sliding plate two is driven by the motor two to slide in the longitudinal direction through the screw rod two. The electric telescopic rod pushes the sliding plate three to move in the vertical direction, thereby realizing fine adjustment of the position of the grinding knife.

[0011] Further, the fixed plate one and the fixed plate two are also slidingly connected to the outer wall of the sliding rail one. They can be freely moved on the sliding rail one by disassembling the screws connected between them, so as to change the distance between the fixed plate one and the fixed plate two to adapt to frames of different lengths, thereby expanding the application range of the device.

[0012] Further, the inner walls of the rotating cylinder and the fixed cylinder are made of soft anti-skid material, so that after they are respectively sleeved on the two ends of the frame, a primary fixing effect on the frame is realized.

[0013] The motor four drives the frame in the rotating cylinder to rotate through the transmission belt, and cooperates with the grinding assembly to drive the grinding knife to move in the transverse and longitudinal directions, so as to realize accurate grinding of the grinding knife on any position on the frame. With this function, the grinding knife can only grind on the specified position on the frame, so that it is not necessary to grind the whole frame.

[0014] Further, the motor five drives the transmission gear meshing with the gear on the gear ring to rotate, so that the gear ring drives the sliding rail three to rotate in the housing one. Since the sliding rail three is in the shape of a spiral and is engaged in the guide groove, it drives the plurality of clamping blocks one on the outer wall of the housing one to slide towards each other or away from each other during the rotation process, thereby realizing automatic uniform clamping of the frame on multiple points by the plurality of clamping blocks one.

[0015] Further, the number of grooves is multiple, which divides the clamping block two into multiple small blocks connected to each other, so as to clamp the outer wall of the frame from multiple directions and strengthen the clamping effect on the frame.

[0016] Further, the clamping block two is made of soft material with elasticity, so it can deform to a certain extent to adapt to frames of different sizes. Through the quickly detachable limiting cylinder, the operator can switch between the two different clamping modes of the clamping block one and the clamping block two according to the needs, so as to adapt to the processing needs of frames of different shapes.

[0017] Further, the processing method comprises the following steps:

[0018] S1: Before processing, the operator first selects the appropriate clamping method in the clamping assembly according to the shape of the frame, such as direct clamping with multiple clamping blocks or indirect clamping with multiple clamping blocks through the limiting cylinder between the clamping blocks, then places the to-be-processed plummet limit frame frame at both ends of the rotating cylinder and the fixed cylinder, and the motor five drives the multiple clamping blocks one to slide towards each other through the slide rail three, realizing direct or indirect clamping of the frame through the limiting cylinder to ensure that the fixing assembly and the clamping assembly can stably fix the frame and realize accurate processing later;

[0019] S2: When the processing starts, the grinding knife is driven by the motor three to rotate at high speed, and when it contacts the surface of the to-be-processed frame, it will form friction with the surface, thereby increasing the roughness of the frame surface; the motor one drives the entire grinding assembly to slide left and right on the slide rail one through the screw one and the sliding plate one, so that the grinding knife can be adjusted in a large range in the transverse direction, which means that the operator can adjust the position of the grinding knife according to the actual size of the frame, thereby covering a longer frame surface in one processing process, avoiding the need for multiple processing, and improving work efficiency;

[0020] S3: During processing, the grinding assembly accurately controls the movement of the grinding knife according to the preset processing path and parameters, realizing roughness processing of the frame surface, the sliding plate two is driven by the motor two to slide in the longitudinal direction through the screw two, and the electric telescopic rod drives the sliding plate three to move in the vertical direction, thereby realizing multi-directional fine adjustment of the position of the grinding knife, so that it can polish at different positions of the frame, which helps to achieve more accurate processing results and improve the stability and reliability of processing quality;

[0021] S4: During processing, the motor four drives the frame in the rotating cylinder through the transmission belt, and cooperates with the grinding assembly in S3 to drive the grinding knife to move in the transverse and longitudinal directions, realizing accurate grinding of the grinding knife on any position of the frame, and with this function, the grinding knife can only grind at the specified position on the frame, such as the position that will contact the plummet, thereby not having to grind the entire frame, reducing processing cost while ensuring use effect;

[0022] S5: After processing is completed, the device automatically stops running, the operator removes the processed plummet limit frame frame, and performs subsequent inspection and use, since a long size of frame is processed at one time, there is no need to repeatedly start and stop, thereby saving time and resources.

[0023] In summary, the present application has the following beneficial technical effects:

[0024] 1. Through the multi-point clamping frame function of the clamping assembly, stable clamping of various shaped frames is realized; through the polishing assembly, the position of the polishing knife can be adjusted in multiple directions and a large range, realizing the effect of being able to process frames of different sizes; the existing limitation frame surface roughness processing device often adopts a two-way clamping method to fix the frame, which limits the shape of the frame that can be processed by the device, thereby limiting the application range of the device; in addition, due to the small movable range of the cutter position of the existing processing device, the size of the frame that can be processed is limited, and multiple repeated start-stop is required, which reduces the work efficiency; the design of the present application greatly improves the limitations of the traditional processing method, thereby improving the work efficiency while ensuring the processing quality and consistency; this innovative solution provides a more efficient and reliable solution for the production and maintenance of electrified railway catenary systems.

[0039] As Figure 4 and Figure 5As shown, the fixing assembly 5 used to fix the frame to be processed and adjust the angle of the frame facing the polishing knife 432, wherein the fixing plate one 51 is fixed on the top outer wall of the slide rail one 2 by screws, the fixing cylinder 511 rotates on the inner wall of the fixing plate one 51, the fixing plate two 52 is fixed on the top outer wall of the slide rail one 2 by screws, the fixing plate one 51 and the fixing plate two 52 also slide on the outer wall of the slide rail one 2, they can be freely moved on the slide rail one 2 by removing the screws between them and the slide rail one 2, so as to change the distance between the fixing plate one 51 and the fixing plate two 52 to adapt to frames of different lengths, thereby expanding the application range of the device; the motor four 53 is fixed on the outer wall of the fixing plate two 52 by screws, the rotating column 531 is fixed on the outer wall of the main shaft of the motor four 53 by welding, the rotating cylinder 55 rotates on the inner wall of the fixing plate two 52 through the rotating shaft, the inner walls of the rotating cylinder 55 and the fixing cylinder 511 are soft anti-skid materials, so that after they are respectively sleeved on the two ends of the frame, the primary fixing effect of the frame is realized; the transmission belt 54 rotates on the outer walls of the rotating column 531 and the rotating cylinder 55 at the same time, the motor four 53 drives the frame in the rotating cylinder 55 to rotate through the transmission belt 54, cooperates with the polishing assembly 4 to drive the polishing knife 432 to move in the horizontal and vertical directions, realizes the accurate polishing of the polishing knife 432 on any position on the frame, with the help of this function, the polishing knife 432 can only polish the specified position on the frame, such as the position that will contact the plummet, so that it is not necessary to polish the whole frame, which reduces the processing cost while ensuring the use effect;

[0040] As Figure 6 、 Figure 7 and Figure 8As shown, the clamping assembly 6, used to improve the adaptability of the device to frames of different shapes, includes a housing 61 fixed to the outer wall of the rotating cylinder 55 by screws, a housing 611 fixed to the outer wall of housing 61 by screws, a motor 62 fixed to the bottom outer wall of housing 61 by welding, a transmission gear 621 fixed to the outer wall of the main shaft of motor 62 by welding, a gear ring 63 rotating on the inner wall of housing 61 by a rotating shaft, and a slide rail 631 fixed to the outer wall of the gear ring 63 by welding. The slide rail 631 is a spiral shape similar to a mosquito coil, providing a track for the sliding of clamping block 64. Clamping block 64 slides on the outer walls of housing 61 and slide rail 631. The frame is clamped in multiple directions by multiple clamping blocks 64. The guide groove 641 is opened on the outer wall of the clamping block 64. The motor 62 drives the transmission gear 621, which meshes with the gear on the gear ring 63, to rotate. This causes the gear ring 63 to drive the slide rail 631 to rotate inside the housing 61. Since the slide rail 631 is spiral in shape and is engaged in the guide groove 641, it drives multiple clamping blocks 64 to slide on the outer wall of the housing 61 in a direction that is closer to or farther from each other during rotation. This enables multiple clamping blocks 64 to automatically and evenly clamp the frame at multiple points, thereby ensuring the stability of the frame during processing and reducing problems such as shaking and displacement during processing.

[0041] like Figure 9 As shown, different weight restraint frames differ in shape. For example, a cylindrical restraint frame requires a more flexible clamping method than clamping block 64 to adapt to different frame shapes. In this case, a limiting cylinder 65 can be added between clamping blocks 64 to solve this problem. The limiting cylinder 65 slides on the inner wall of housing 61, and the fixing cover 651 rotates on the outer wall of the limiting cylinder 65 via a pivot. Clamping block 652 is fixed to the inner wall of the fixing cover 651 by a snap-fit. A groove 653 is formed on the outer wall of clamping block 652. There are multiple grooves 653. Clamping block 652... 52 is divided into multiple interconnected small blocks, thereby clamping the outer wall of the frame from multiple directions, strengthening the clamping effect on the frame, reducing the probability of frame displacement during processing, and improving processing stability; Clamping block 2 652 is made of a flexible soft material, so it can deform to a certain extent to adapt to frames of different sizes; Through the quick-release limiting cylinder 65, the operator can switch between two different clamping methods, clamping block 1 64 and clamping block 2 652, as needed to adapt to the processing requirements of frames of different shapes, thereby improving the applicability and flexibility of the device;

[0042] The present invention provides a method for improving the surface roughness of the inner sinker restraint frame, comprising the following steps:

[0043] S1: Before processing, the operator first selects the appropriate clamping method in the clamping assembly 6 according to the shape of the frame, such as directly clamping with multiple clamping blocks 64 or using clamping blocks 652 by placing a limiting cylinder 65 between the clamping blocks 64, then placing the to-be-processed plummet limit frame frame at both ends inside the rotating cylinder 55 and the fixed cylinder 511, the motor five 62 drives the gear ring 63 to drive multiple clamping blocks 64 to slide towards each other through the sliding rail three 631, realizing direct or indirect clamping of the frame through the limiting cylinder 65, to ensure that the fixing assembly 5 and the clamping assembly 6 can stably fix the frame and realize accurate processing later;

[0044] S2: When the processing starts, the polishing knife 432 is driven by the motor three 431 to rotate at high speed, and when it contacts the surface of the to-be-processed frame, it will form friction with the surface, thereby increasing the roughness of the frame surface; the motor one 3 drives the sliding plate one 41 to drive the entire polishing assembly 4 to slide left and right on the sliding rail one 2 through the screw one 31, so that the polishing knife 432 can be adjusted in a large range in the transverse direction, which means that the operator can adjust the position of the polishing knife 432 according to the actual size of the frame, thereby covering a longer frame surface in one processing process, avoiding the need for multiple processing, and improving work efficiency;

[0045] S3: During processing, the polishing assembly 4 will accurately control the movement of the polishing knife 432 according to the preset processing path and parameters to process the roughness of the frame surface, the sliding plate two 42 is driven by the motor two 412 to slide in the longitudinal direction through the screw two 413, and the electric telescopic rod 421 pushes the sliding plate three 43 to move in the vertical direction, thereby realizing multi-directional fine adjustment of the position of the polishing knife 432, so that it can polish at different positions of the frame, which helps to achieve more accurate processing results and improve the stability and reliability of processing quality;

[0046] S4: During processing, the motor four 53 drives the frame in the rotating cylinder 55 to rotate through the transmission belt 54, cooperating with the polishing assembly 4 in S3 to drive the polishing knife 432 to move in the transverse and longitudinal directions, realizing accurate polishing of the polishing knife 432 on any position of the frame. With this function, the polishing knife 432 can only polish at specified positions on the frame, such as positions that will contact the plummet, so that the entire frame does not need to be polished, reducing processing costs while ensuring use effect;

[0047] S5: After processing is completed, the device will automatically stop running, and the operator will remove the processed plummet limit frame frame for subsequent inspection and use. Since a long size of the frame is processed at one time, there is no need to start and stop repeatedly, thereby saving time and resources.

[0048] In summary, the technical scheme provided by the present application can adjust the position of the polishing cutter 432 in multiple directions and a wide range through the polishing assembly 4, so that frames of different sizes can be processed. The problem that the existing frame surface roughness processing device is limited in the shape of the frame that can be processed due to the fact that the frame is often fixed by a two-way clamping method, thereby limiting the application range of the device is solved. In addition, the problem that the size of the frame that can be processed is limited due to the small movable range of the position of the cutter of the existing processing device, and the work efficiency is reduced due to the need for repeated start and stop is solved.

[0049] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
