Description

Technical Field

[0001] The invention belongs to the technical field of overhead wire hanging string processing, and in particular relates to a crimping tube feeding and caching device suitable for overhead wire hanging string processing. Background Art

[0002] With the rapid development of my country's railway construction, new requirements have been put forward for the process quality standards of relevant components in the railway industry, and the requirements for the construction and maintenance accuracy of the driving line are getting higher and higher. In the railway driving line, the overhead contact network is an important part to ensure the normal operation of the railway. It is connected to the electric railway power supply line and is responsible for supplying power to the entire electric locomotive traction system and train ancillary equipment.

[0003] In the contact network system of the train, the suspension string is an indispensable structure, which is mainly used to stably suspend the contact line under the load-bearing cable, ensure the stability and safety of the contact line setting, and ensure that the contact line can be reliably matched with the pantograph on the top of the train.

[0004] In the pre-assembly process of overhead wire hanging strings, the application of crimping tubes is often indispensable, and the existing crimping tube loading, clamping, and pressing processes often rely on the operation of skilled workers. In addition, the crimping tubes are of different sizes and shapes, and the amount is huge, which leads to cumbersome manual operation procedures, high labor intensity, low production efficiency, and high suspension processing costs. At the same time, manual assembly of crimping tubes is difficult to guarantee product quality, the consistency of product performance is poor, and the qualified rate is low. There is a risk of crimping failure of the crimping tube in later applications.

[0005] In addition, in the existing pre-assembly production of suspension strings, there is no concept of crimping tube cache. When workers need to assemble a suspension string, they have to take two crimping tubes. The above-mentioned defects of manual operation also exist, and the continuity of the suspension string processing is poor. Summary of the invention

[0006] In response to one or more of the above defects or improvement needs in the prior art, the present invention provides a crimping tube loading and caching device suitable for contact network hanging string processing, which can effectively realize the caching of crimping tubes during the hanging string processing, ensure the continuous loading of crimping tubes, and reduce the manual labor in the crimping tube loading process.

[0007] To achieve the above-mentioned purpose, the present invention provides a crimping tube feeding and caching device suitable for processing catenary suspension strings, characterized in that it comprises a crimping tube vibration plate, a crimping tube channel and a crimping tube material taking tool;

[0008] The compression tube vibration plate has a cavity structure of a certain depth, which is used to accommodate the compression tube and transmit the compression tube vibration to the compression tube channel;

[0011] As a further improvement of the present invention, the accommodating groove is opened on the side of the material taking block facing the outlet end of the compression tube channel, and a baffle is arranged on the end face of the side of the material taking block; the baffle is fixed on the end face of the material taking block and can block the outlet end of the compression tube channel when the material taking block moves to the loading position.

[0012] As a further improvement of the present invention, the compression-tube brake plate includes a vibration plate surrounding plate and a vibration plate bottom plate; the vibration plate surrounding plate is circumferentially wrapped around the outer periphery of the vibration plate bottom plate; the vibration plate bottom plate is a vibration actuating mechanism.

[0013] As a further improvement of the present invention, the vibration disk bottom plate is also a rotatable mechanism for frictionally accelerating the crimping tube to move toward the crimping tube channel.

[0014] As a further improvement of the present invention, the bottom plate of the vibration plate is also a lifting mechanism, which is used to move the stacked multiple layers of compression tubes to the compression tube channel in a manner of vibrating and lifting;

[0015] At the same time, the inlet end of the compression tube channel is arranged on the upper part of the compression tube vibration plate.

[0016] As a further improvement of the present invention, the vibration plate bottom plate is also a lifting and rotating mechanism, which is used to accelerate the stacked multi-layer compression tubes to the compression tube channel in a manner of vibrating, lifting and rotating;

[0017] At the same time, the inlet end of the compression tube channel is arranged on the upper part of the compression tube vibration plate.

[0018] As a further improvement of the present invention, the height of the inlet end of the crimping tube channel is higher than the height of the outlet end thereof, so that the crimping tube can move from the inlet end to the outlet end under the action of gravity.

[0019] As a further improvement of the present invention, the compression tube channel includes a pair of oppositely arranged channel side plates and a channel bottom plate arranged between the two channel side plates; the channel bottom plate is arranged at a height lower than the top of the channel side plates.

[0020] As a further improvement of the present invention, the crimp tube material removal tooling further includes a lifting block, a lifting mechanism and a mounting plate;

[0021] The material taking block is arranged on the lifting block, and the lifting block corresponds to and matches the output end of the lifting mechanism; the mounting plate is fixedly connected to the lifting mechanism and is used for the installation of the crimping tube material taking tooling.

[0022] As a further improvement of the present invention, the width of the inlet end of the crimping tube channel is greater than the width of the outlet end thereof.

[0023] The above-mentioned improved technical features can be combined with each other as long as they do not conflict with each other.

[0024] In general, the above technical solution conceived by the present invention has the following beneficial effects compared with the prior art:

[0025] (1) The crimp tube feeding and caching device suitable for contact network suspension string processing of the present invention guides each crimp tube to the crimp tube picking tooling to wait for being grabbed and fed by constructing a crimp tube vibration plate and a crimp tube channel, thereby providing conditions for the feeding and grabbing mechanism to automatically and continuously supply crimp tubes, replacing traditional manual feeding, and having the characteristics of high efficiency, precision, and high degree of automation. It solves the problem of automatic feeding and assembly of crimp tubes, constitutes an important part of the feeding of the suspension string pre-assembly automatic production line, reduces the extra manual labor introduced by the feeding and caching of crimp tubes during the suspension string processing, reduces the labor intensity and labor cost of the suspension string processing, improves the degree of automation of the suspension string assembly, and reduces the cost of the suspension string assembly.

[0026] (2) The crimped tube feeding and caching device of the present invention, which is suitable for the processing of contact network hanging strings, adopts a crimped tube vibration plate to vibrate and convey a large number of crimped tubes stored therein, adopts a tangentially contracted crimped tube channel to arrange the crimped tubes in a single row linearly, and the crimped tubes discharged from the end of the crimped tube channel are supported and limited one by one by a crimped tube picking tool, thereby creating favorable conditions for grabbing by the grabbing equipment of the next workstation; thereby, crimped tube caching and continuous automatic loading are realized without manual operation, reducing labor intensity, improving productivity, and enhancing product quality and stability of batch operations.

[0027] (3) The crimping tube loading and caching device suitable for contact network hanging string processing of the present invention particularly has a crimping tube vibration plate bottom plate constructed in a liftable and / or rotatable manner. The liftable vibration bottom plate can store more layers of crimping tubes stacked together, eliminating the need for frequent addition of crimping tubes, thereby increasing the single-time storage capacity; the rotatable vibration bottom plate can provide friction force along the circumferential tangential direction for the crimping tube, making it easier for the crimping tube to enter the crimping tube channel and running faster.

[0028] (4) The crimping tube loading and caching device suitable for contact network hanging string processing of the present invention particularly constructs the crimping tube channel to be wider at the entrance and narrower at the exit, which not only prevents blockage at the entrance but also ensures the smoothness of single discharge at the exit. Furthermore, the overall width of the channel can be adjusted in time by moving the movable side plate, and crimping tubes of different sizes and shapes can be automatically adjusted to adapt.

[0029] (5) The crimping tube loading and caching device of the present invention is suitable for contact network hanging string processing, and in particular, a baffle is arranged at the outlet end of the crimping tube channel corresponding to the crimping tube material taking tool. The baffle follows the corresponding movement of the material taking block, so that the baffle can close the outlet end when a single crimping tube is supporting and loading, thereby preventing the crimping tube in the crimping tube channel from falling, ensuring that the crimping tubes in the crimping tube channel can be accurately taken one by one, and further improving the accuracy of crimping tube taking.

[0039] Example:

[0040] See also Figure 1 , 2The compression tube feeding and caching device suitable for contact network hanging string processing in the preferred embodiment of the present invention comprises a compression tube vibration plate 410, a compression tube channel 411 and a compression tube picking tool 412. The compression tube vibration plate 410 is used to realize the storage of compression tubes 413 and the feeding to the compression tube channel 411; the two ends of the compression tube channel 411 are respectively connected to the compression tube vibration plate 410 and the compression tube picking tool 412, which are used to send compression tubes 413 one by one to the compression tube picking tool 412, and realize the caching before the feeding of several compression tubes 413; the compression tube picking tool 412 is used to realize the one-by-one feeding of compression tubes 413 in the compression tube channel 411, realize the support and limit of each compression tube 413, so that the compression tube feeding device can feed it to the next station.

[0041] Specifically, multiple sets of compression tube channels 411 and compression tube material pick-up tools 412 can be arranged in multiple tangential directions on the circumference of the compression tube vibration plate 410. By constructing the compression tube vibration plate 410 and the compression tube channels 411, the compression tubes 413 are guided to the compression tube material pick-up tool 412 to wait for being grabbed, so that the subsequent compression tube feeding device can automatically and continuously feed the compression tubes 413, replacing the traditional manual feeding. It has the characteristics of high efficiency, precision, and high degree of automation, solves the problem of automatic feeding and assembly of compression tubes, and constitutes an important part of the feeding process of the suspension string pre-assembly automatic production line.

[0042] More specifically, the compression tube vibration plate 410 in the preferred embodiment includes a vibration plate enclosure 4101 and a vibration plate bottom plate 4112. The vibration plate enclosure 4101 is a ring plate structure with a circular cross section, which surrounds the outer periphery of the vibration plate bottom plate 4102 and forms a compression tube storage cavity of a certain depth above the vibration plate bottom plate 4102. At the same time, the vibration plate bottom plate 4102 is a vibration actuation mechanism, which can realize the driving and feeding of the compression tube 413 through vibration, and it is inclined toward the entrance of the compression tube channel 411, which facilitates the feeding of the compression tube 413 to the compression tube channel 411.

[0043] Furthermore, when there are multiple sets of compression tube channels 411, the middle of the vibration plate bottom plate 4102 is raised, and inclined bottom plate end surfaces are respectively provided corresponding to the multiple channel entrances. Of course, a vibration plate top plate can also be provided on the top of the vibration plate enclosure 4101 to form a closed accommodation space, but an injection window for the compression tube 413 is reserved on the top plate.

[0044] Further preferably, the vibration plate bottom plate 4102 is a lifting mechanism, which is used to move the stacked multiple layers of compression tubes to the compression tube channel 411 in a manner of lifting and vibrating, at which point one end of the compression tube channel 411 is connected to the upper part of the vibration plate enclosure 4101. In another preferred embodiment, the vibration plate bottom plate 4102 is configured as a rotatable mechanism, which is used to accelerate the compression tube friction to the compression tube channel 411. Alternatively, the vibration plate bottom plate 4102 can also be lifted and rotated at the same time, which is used to accelerate the stacked multiple layers of compression tubes to the compression tube channel 411 in a manner of lifting and vibrating and rotating; at this point, one end of the compression tube channel 411 is connected to the upper part of the vibration plate enclosure 4101. The present invention particularly structures the vibration plate bottom plate in a lifting and / or rotatable manner. The lifting vibration plate bottom plate can store more layers of compression tubes stacked together, without the need to frequently add compression tubes, thereby increasing the single storage capacity; the rotatable vibration plate bottom plate can provide friction along the circumferential tangential direction for the compression tube, making it easier to enter the compression tube channel, and the operation speed is faster.

[0045] Furthermore, the crimped tube channel 411 includes a channel bottom plate 4111 and a channel side plate 4112; it may also include a crimped tube channel top plate to form a closed or semi-closed space, and the channel top plate may be made of a transparent or semi-transparent material for easy observation. The channel side plates 4112 are arranged in pairs and are arranged on both sides of the channel bottom plate 4111, and the channel bottom plate 4111 is clamped between the two side plates, and the setting height of the channel bottom plate 4111 is lower than the top of the channel side plate 4112, forming a through groove structure with a certain depth.

[0046] Furthermore, the width of the crimping tube channel entrance (close to the crimping tube vibration disk 410) is greater than the width of the crimping tube outlet (close to the crimping tube material removal tool 412). At the same time, the two channel side plates 4112 preferably include fixed side plates and movable side plates, and the movable side plates can be moved relative to the fixed side plates to adjust the horizontal width of the through-groove structure. Preferably, the channel bottom plate 4111 is inclined, and the vertical height at the entrance is higher than the height at the outlet (i.e., extending obliquely downward from one side of the crimping tube vibration disk 410 to one side of the crimping tube material removal tool 412), which is used to accelerate the flow of the crimping tube 413. Further preferably, the inclination angle of the channel bottom plate 4111 is adjustable, and the flow rate of the crimping tube 413 can be accelerated or slowed down as needed.

[0047] In a preferred embodiment of the present invention, the crimping tube channel is specially constructed to be wider at the entrance and narrower at the exit, which not only prevents blockage at the entrance but also ensures the smoothness of single discharge at the exit. At the same time, the through-slot width of the channel can be adjusted in time by moving the movable side plate to meet the caching and feeding requirements of crimping tubes of different sizes and shapes.

[0048] Furthermore, the crimping tube material removal tool 412 includes a lifting block 4121, a lifting mechanism 4122, a mounting block 4123, and a material removal block 4124. Among them, the lifting block 4121 is matched and arranged at the output end of the lifting mechanism 4122, and can be vertically lifted and lowered under the drive of the lifting mechanism 4122. The lifting mechanism 4122 in the preferred embodiment is a lifting cylinder, which is arranged at the bottom of the lifting block 4121. At the same time, the mounting block 4123 is arranged on one side of the lifting mechanism 4122, and is fixedly connected to the lifting mechanism 4122, and is used to fix the lifting mechanism 4122 on the corresponding workbench. The material taking block 4124 is arranged on the top of the lifting block 4121, one side of which is directly opposite to the outlet of the crimping tube channel 411, and a receiving groove 4125 is provided on the side end surface for realizing the limiting and receiving of the crimping tube 413. In a preferred embodiment, two material taking plates are arranged side by side on the top of the material taking block 4124, and material taking grooves are respectively provided on the two material taking plates, and the two material taking grooves are horizontally coaxial, such as Figure 2 Preferably, in the preferred embodiment, the length of the receiving groove 4125 in the direction of the crimping tube channel 411 is not less than the width of the crimping tube 413 , so as to ensure that the crimping tube 413 can be reliably accommodated in the receiving groove 4125 .

[0049] Further, a baffle (not shown in the drawings) is vertically arranged on one side of the lifting block 4121 and the lifting mechanism 4122 near the crimping tube channel 411, and the top of the baffle is fixed below the accommodating groove 4125, so that when the lifting block 4121 rises, the baffle can close the outlet of the crimping tube channel 411 to prevent the crimping tube 413 at the outlet from falling. In a preferred embodiment of the present invention, the corresponding arrangement of the material taking block 4124 at the outlet of the crimping tube channel 411 allows the crimping tube 413 in the crimping tube channel 411 to be taken one by one, preventing the crimping tube from rotating in the horizontal plane, ensuring the continuity and accuracy of the material taking, and creating convenient conditions for the subsequent feeding device to grab. Of course, the above-mentioned vertical arrangement of the baffle is correspondingly arranged based on the vertical lifting process of the lifting block 4121. When the material taking block 4124 is arranged on the horizontal block for horizontal movement, a horizontal baffle can be arranged on the material taking block 4124, which can be specifically selected according to actual needs.

[0050] The crimping tube feeding and caching device suitable for contact network hanging string processing in the present invention has a simple structure and is easy to operate. It adopts a crimping tube vibration plate to vibrate and convey a large number of crimping tubes stored therein, adopts a tangentially contracted crimping tube channel to arrange the crimping tubes in a single row linearly, and the crimping tubes discharged from the end of the crimping tube channel are supported and limited one by one by a crimping tube picking tool, thereby creating favorable conditions for grabbing by the grabbing equipment of the next workstation; thereby, crimping tube caching and continuous automatic loading are realized, without the need for manual operation, reducing labor intensity, improving production efficiency, enhancing product quality and stability of batch operations, reducing the cost of hanging string processing, and having good application prospects and promotion value.

[0051] It will be easily understood by those skilled in the art that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
