Description

Technical Field

[0001] The present invention belongs to the field of suspension string pre-assembly processing and production, and more specifically, relates to a connecting wire clamp buffer unit of a suspension string pre-assembly processing production line. Background Art

[0002] The catenary system is a high-voltage transmission line installed in a zigzag pattern above the rails on electrified railways, supplying current to the pantographs. The catenary system is the main structure of railway electrification projects and is a specialized transmission line installed above the railway lines to supply power to electric locomotives. It consists of contact suspensions, support devices, positioning devices, supports, and foundations.

[0003] The catenary is a specialized transmission line installed overhead along a railway line, supplying power to electric locomotives. It consists of a contact suspension, support devices, positioning devices, supports, and foundations. The contact suspension includes contact wires, droppers, load-bearing cables, connecting components, and insulators. The contact suspension is mounted on the supports via support devices and transmits electrical energy from the traction substation to the electric locomotives.

[0004] In the existing pre-assembly production of suspension strings, the assembly of connecting wire clamps basically relies on the operation of skilled workers. However, connecting wire clamps vary in size and shape and are used in large quantities, resulting in cumbersome manual operation procedures, high labor intensity for workers, and low production efficiency. At the same time, manual assembly of connecting wire clamps is difficult to guarantee product quality and has a low pass rate. The operating and maintenance units reported that the operating lines had varying degrees of suspension string breakage. After research, it was found that the cause of the suspension string breakage was closely related to the assembly of the connecting wire clamps.

[0005] In the existing pre-assembly production of suspension strings, the connecting wire clamps are placed in a rather messy manner in the material basket. When a worker needs to assemble a suspension string, he or she has to take two connecting wire clamps. Due to the above-mentioned defects of manual operation, the continuity of the suspension string processing is poor. Summary of the Invention

[0006] In response to the above defects or improvement needs of the prior art, the present invention provides a connecting wire clamp cache unit for an intelligent suspension string pre-assembly processing production line, which can effectively realize the caching of connecting wire clamps during the suspension string processing process, ensure the continuous loading of connecting wire clamps, and reduce the amount of manual labor in the loading process of connecting wire clamps.

[0007] To achieve the above-mentioned object, according to one aspect of the present invention, a connecting wire clamp cache unit for an intelligent suspension string pre-assembly production line is provided, characterized in that it comprises a frame, a connecting wire clamp vibration plate, a connecting wire clamp discharge channel, a connecting wire clamp feeding cylinder, and a connecting wire clamp cache mold, wherein:

[0009] The connecting wire clamp feeding cylinder is installed on the frame, and the connecting wire clamp cache mold is installed on the output shaft of the connecting wire clamp feeding cylinder to drive the connecting wire clamp cache mold to move up and down. The connecting wire clamp cache mold is correspondingly arranged at the outlet of the connecting wire clamp discharge channel, and an accommodating space is provided on the connecting wire clamp cache mold to accommodate the connecting wire clamp coming out of the connecting wire clamp discharge channel.

[0010] Preferably, a direction selection mechanism is further provided at the entrance of the spiral feeding channel for allowing a connection wire clamp with a set posture to pass through.

[0011] Preferably, the direction selection mechanism includes a scraper installed on the spiral feeding channel and a return spring connected to the scraper for returning the scraper to its original position. The return spring is located in the spiral feeding channel. One end of the scraper is exposed from the spiral feeding channel and can be pressed into the spiral feeding channel by the bottom of the connecting wire clamp.

[0012] Preferably, the tangent line at the outlet of the spiral feeding channel is perpendicular to the discharge channel of the connecting wire clamp.

[0013] Preferably, a blocking plate is vertically provided on one side of the connecting wire clamp cache mold close to the connecting wire clamp discharge channel, so as to block the connecting wire clamp in the connecting wire clamp discharge channel after the connecting wire clamp in the mold rises.

[0016] Preferably, the connecting wire clamp cache mold includes a limit stop and a support platform; the limit stop is used to block the movement of the connecting wire clamp along the forward direction of the connecting wire clamp discharge channel, and the support platform is used to support the connecting wire clamp coming out of the connecting wire clamp discharge channel.

[0017] Preferably, the connecting wire clip cache mold further comprises a guide platform located above the support platform for guiding the connecting wire clip into the connecting wire clip cache mold.

[0018] Preferably, a notch is provided on the connecting wire clamp cache mold so that the pneumatic clamp connected to the end of the six-axis robot can clamp the connecting wire clamp.

[0019] In general, the above technical solutions conceived by the present invention can achieve the following beneficial effects compared with the prior art:

[0020] 1) The present invention constructs a connecting wire clamp vibration plate and a connecting wire clamp discharge channel to guide the connecting wire clamps one by one to the connecting wire clamp cache mold to wait for being grabbed and loaded, thereby providing conditions for the loading and grabbing mechanism to automatically and continuously supply the connecting wire clamps, replacing traditional manual loading. It has the characteristics of high efficiency, precision, and high degree of automation, solves the problem of automatic loading and assembly of connecting wire clamps, and constitutes an important link in the loading of the automatic production line for pre-assembly of suspension strings. It reduces the extra manual labor introduced by the loading and caching of connecting wire clamps during the suspension string processing process, reduces the labor intensity and labor cost of suspension string processing, improves the degree of automation of suspension string assembly, and reduces the cost of suspension string assembly.

[0022] 3) The present invention constructs the discharge channel of the connecting wire clamp 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 individual discharge at the exit. Furthermore, the overall width of the channel can be adjusted in time by moving the movable side plate, and connecting wire clamps of different sizes and shapes can be automatically adjusted to adapt.

[0023] 4) The present invention sets a blocking plate on the connecting wire clamp cache mold corresponding to the outlet end of the connecting wire clamp discharge channel, and uses the corresponding movement of the blocking plate to close the outlet end of the connecting wire clamp discharge channel when a single connecting wire clamp is supporting and loading, thereby preventing the connecting wire clamp in the connecting wire clamp discharge channel from falling, ensuring that the connecting wire clamps in the connecting wire clamp discharge channel can be accurately taken out one by one, and further improving the accuracy of the connecting wire clamp taking out.

[0027] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the present invention and are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

[0028] like Figures 1 to 3 As shown, a connecting wire clamp 4208 cache unit of an intelligent hanging string pre-assembly processing production line includes a frame, a connecting wire clamp vibration plate 4201, a connecting wire clamp discharge channel 4202, a connecting wire clamp feeding cylinder 4203 and a connecting wire clamp cache mold 4204, wherein:

[0029] The connecting wire clamp vibration plate 4201 is installed on the frame, and the connecting wire clamp vibration plate 4201 includes a connecting wire clamp vibration plate body 4205 for storing the connecting wire clamp 4208 and a spiral feeding channel 4206 installed on the inner wall of the connecting wire clamp vibration plate body 4205, the outlet of the spiral feeding channel 4206 is connected to the inlet of the connecting wire clamp discharge channel 4202, and the height of the outlet of the connecting wire clamp discharge channel 4202 is less than the height of the inlet of the connecting wire clamp discharge channel 4202;

[0030] The connecting wire clamp loading cylinder 4203 is installed on the frame, and the connecting wire clamp cache mold 4204 is installed on the output shaft of the connecting wire clamp loading cylinder 4203 to drive the connecting wire clamp cache mold 4204 to move up and down. The connecting wire clamp cache mold 4204 is correspondingly arranged at the outlet of the connecting wire clamp discharge channel 4202, and the connecting wire clamp cache mold 4204 is provided with an accommodating space 4207 to accommodate the connecting wire clamp 4208 coming out of the connecting wire clamp discharge channel 4202. The two ends of the connecting wire clamp discharge channel 4202 are respectively connected to the spiral feeding channel 4206 and the connecting wire clamp cache mold 4204, which is used to feed the connecting wire clamps 4208 one by one to the connecting wire clamp cache mold 4204 and realize the buffering of several connecting wire clamps 4208 before loading. The connecting wire clamp cache mold 4204 is used to realize the individual removal of the connecting wire clamps 4208 from the connecting wire clamp discharge channel 4202, and realize the support and limit of each connecting wire clamp 4208 so that the connecting wire clamp 4208 feeding device can load it to the next workstation. The material removal station can use manual assistance to adjust the posture of the connecting wire clamp 4208 and remove the material, or it can be automatically removed by a six-axis robot.

[0031] Reference Figure 3 As a preferred embodiment, a direction selection mechanism 4216 is further provided at the entrance of the spiral feeding channel 4206 to cooperate with the inclined surface 4219 on the connecting wire clamp 4208, thereby allowing the connecting wire clamp 4208 with a set posture to enter the spiral feeding channel 4206. Referring to the accompanying drawings, as a preferred embodiment, the selection mechanism 4216 includes a scraper 4217 installed on the spiral feeding channel 4206 and a return spring 4218 connected to the scraper 4217 for returning the scraper 4217. The return spring 4218 is located in the spiral feeding channel 4206, and one end of the scraper 4217 is exposed from the spiral feeding channel 4206 and can be pressed into the spiral feeding channel 4206 by the bottom of the connecting clamp 4208. The scraper 4217 can cooperate with one of the inclined surfaces 4219 on the connecting clamp 4208, and the inclined surface 4219 can pass through the scraper 4217, so that the connecting clamp 4208 can pass through the scraper 4217 without falling. If the posture of the connecting clamp 4208 is not appropriate, when other parts, especially the end, are in hard contact with the scraper 4217, it will be blocked and fall from the spiral feeding channel 4206. The scraper 4217 can be a scraper with a tip, or a rod, and the elastic force of the return spring 4218 should be appropriate to ensure that the scraper 4217 can be pressed down by the connecting clamp 4208 and can return to its original position. The return spring 4218 can be an existing spring 4218 such as a compression spring 4218 or a torsion spring.

[0032] Alternatively, the selection mechanism 4216 includes a vertical plate installed on the spiral loading channel 4206, and the vertical plate is installed on the side of the spiral loading channel 4206 away from the inner wall of the connecting wire clamp vibration disk body 4205. The distance between the vertical plate and the inner wall of the connecting wire clamp vibration disk body 4205 is slightly larger than the maximum width of the connecting wire clamp 4208. The connecting wire clamp 4208 is only allowed to pass through the vertical plate along the longitudinal movement of the connecting wire clamp 4208 itself. The skewed connecting wire clamp 4208 cannot pass through and falls.

[0033] Furthermore, the tangent line at the exit of the spiral feeding channel 4206 is perpendicular to the connecting wire clamp discharge channel 4202, allowing the connecting wire clamp 4208 to enter the connecting wire clamp 4208 buffer mold in a set posture, facilitating the six-axis robot to remove the material. A limit plate can also be provided on the vibration plate body at the position corresponding to the exit of the spiral feeding channel 4206 to limit the further forward movement of the connecting wire clamp 4208, so that the connecting wire clamp 4208 can only enter the connecting wire clamp discharge channel 4202.

[0034] Furthermore, a blocking plate 4209 is vertically provided on one side of the connecting wire clip cache mold 4204 near the connecting wire clip discharge channel 4202. This is used to block the connecting wire clip 4208 in the connecting wire clip discharge channel 4202 after the connecting wire clip 4208 in the mold rises. By correspondingly moving the blocking plate 4209, the blocking plate 4209 can close the outlet end of the connecting wire clip discharge channel 4202 when a single connecting wire clip 4208 is supporting and loading the material, thereby preventing the connecting wire clip 4208 in the connecting wire clip discharge channel 4202 from falling, ensuring that the connecting wire clips 4208 in the connecting wire clip discharge channel 4202 can be accurately removed one by one, further improving the accuracy of the connecting wire clip 4208 removal.

[0035] Furthermore, the connecting wire clamp discharge channel 4202 includes a channel bottom plate 4210 and two side plates 4211 mounted on the channel bottom plate 4210. The distance between the two channel side plates 4211 at the entrance of the connecting wire clamp discharge channel 4202 is greater than the distance at the exit of the connecting wire clamp discharge channel 4202. One of the side plates 4211 is a fixed side plate 4211, and the other side plate 4211 is a movable side plate 4211. The movable side plate 4211 is movable relative to the fixed side plate 4211 to adjust the width of the connecting wire clamp discharge channel 4202. The connecting wire clamp discharge channel 4202 is constructed to be wider at the entrance and narrower at the exit, which prevents blockage at the entrance and ensures smooth single discharge at the exit. Furthermore, the overall width of the channel can be timely adjusted by moving the movable side plates 4211, and connecting wire clamps 4208 of different sizes and shapes can all automatically adjust to adapt.

[0036] Furthermore, the connecting wire clamp cache mold 4204 includes a limit stop 4212 and a support platform 4213; the limit stop 4212 is used to block the movement of the connecting wire clamp 4208 along the forward direction of the connecting wire clamp discharge channel 4202, and the support platform 4213 is used to support the connecting wire clamp 4208 coming out of the connecting wire clamp discharge channel 4202.

[0037] Furthermore, the connecting wire clamp cache mold 4204 also includes a guide platform 4214 located above the support platform 4213, for guiding the connecting wire clamp 4208 into the connecting wire clamp cache mold 4204. A plurality of long holes are also provided on the connecting wire clamp cache mold 4204. The guide platform 4214 can adjust its position within the long holes to better adapt to the shape and position of one end of the connecting wire clamp 4208 with a circular hole, so that the connecting wire clamp 4208 can more conveniently enter the accommodating space 4207 of the connecting wire clamp cache mold 4204.

[0038] Furthermore, a notch 4215 is provided on the connecting wire clamp cache mold 4204 so that the pneumatic clamp connected to the end of the six-axis robot can clamp the connecting wire clamp 4208.

[0039] The connecting wire clamp 4208 loading 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 connecting wire clamp vibration disk 4201 to vibrate and convey a large number of connecting wire clamps 4208 stored therein, and adopts a tangentially contracted connecting wire clamp 4208 channel to arrange the connecting wire clamps 4208 in a single row linearly. The connecting wire clamps 4208 discharged from the end of the connecting wire clamp 4208 channel are supported and limited one by one by a connecting wire clamp cache mold 4204, creating favorable conditions for grasping by the grasping equipment of the next workstation; thereby, the caching and continuous automatic loading of the connecting wire clamp 4208 are realized without manual operation, which reduces labor intensity, improves production efficiency, enhances product quality and stability of batch operations, reduces the cost of hanging string processing, and has good application prospects and promotion value.

[0040] It will be easily understood by those skilled in the art that the above description is merely a preferred embodiment of the present invention and is 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 scope of protection of the present invention.
