Description

Technical Field

[0001] The invention relates to the technical field of rod storage, and in particular to a disconnector connecting rod storage and retrieval system and a retrieval method. Background Art

[0002] The connecting rod used in the disconnector is an important connecting component between the operating mechanism and the moving contact of the disconnector. When the operating mechanism is actuated, the connecting rod will transmit the force or torque, so that the moving contact can be opened or closed at the fixed position of the static contact, and ensure that all phases can operate synchronously.

[0003] The connecting rod used in the isolating switch is relatively long, and the length and cross-sectional shape of the connecting rod used in different types of isolating switches are also different. At present, the storage method of the connecting rods for isolating switches is mostly to stack connecting rods of different types in the same place. When assembling and using, the connecting rod of the appropriate type is manually selected from the storage site and the connecting rod is taken out from the storage site.

[0004] The existing three-dimensional container systems are mostly used for storing box-type goods, and are not suitable for rod-shaped profiles such as connecting rods. It is difficult to take and put the connecting rods, and the connecting rods are still stacked together when stored, resulting in connecting rods of different models being mixed together, making it difficult to classify and take and use them. Connecting rods stacked together are also prone to crushing the bottom connecting rods, causing the bottom connecting rods to deform, and it is difficult to manually check the appearance of the connecting rods during storage; in addition, the connecting rods are stacked together, and the surface of the connecting rods that are not used for a long time cannot be cleaned or anti-corrosion treated, such as applying an appropriate amount of anti-rust oil or lubricant, which makes the surface of the connecting rods very easy to rust and damage. Summary of the invention

[0018] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical scheme of the present invention will be clearly and completely described below in conjunction with the drawings in this specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0019] Example 1 In a typical embodiment of the present invention, Figure 1-Figure 3 As shown, a disconnector connecting rod storage and retrieval system is proposed, including: a three-dimensional shelf group and a pick-and-place device. The three-dimensional shelf group is composed of a plurality of three-dimensional shelves 1 arranged in sequence and spaced apart, so as to classify and store connecting rods 17 of different types. The pick-and-place device is movably arranged near the three-dimensional shelf 1, so as to automatically remove and move out the connecting rod 17 on the three-dimensional shelf 1, without the need for manual entry into the three-dimensional shelf group, thus reducing the labor intensity. In addition, the setting of the three-dimensional shelf 1 facilitates the arrangement of the connecting rod 17, and facilitates the classified storage and maintenance of the connecting rod 17.

[0020] Specifically, the three-dimensional shelf 1 includes a plurality of vertical frames, horizontal frames and support frames, wherein the vertical frames are vertically fixed on the ground, and the horizontal frames are horizontally fixed on the vertical frames by welding, bolt connection, etc. The vertical frames and the horizontal frames are combined to form the main structure of the three-dimensional shelf 1, and a plurality of support frames are evenly fixed on one side of the main structure obliquely upward to support the connecting rod 17. The plurality of support frames are divided into a plurality of layers to improve space utilization. The support frames are at an angle of 2° with the horizontal plane. While ensuring that the connecting rod 17 will not automatically roll off the support frames, it can also avoid the connecting rods 17 from being stacked and squeezed together, thereby preventing the connecting rods 17 from being squeezed and deformed.

[0021] In this embodiment, in order to effectively limit the position of the connecting rod 17 and avoid extrusion between the connecting rods 17, a plurality of limit grooves are arranged on the support frame at intervals along its length direction, and the connecting rod 17 is placed in the limit groove 17 to limit the position of the connecting rod 17.

[0022] It should be noted that the gap between two adjacent limit grooves on the same support frame should not be too large to avoid excessive waste of storage space, and the depth should not be too deep to prevent affecting the pulling and removal of the connecting rod 17. The sizes of the limit grooves on different three-dimensional shelves 1 and different layers are also different to meet the storage requirements of different models of connecting rods 17.

[0023] The picking and placing device includes a walking mechanism and a picking and placing mechanism 4. The picking and placing mechanism 4 is fixedly arranged on the walking mechanism, and the walking mechanism is arranged on the track 2, so that the picking and placing mechanism 4 is driven by the walking mechanism to move to the specified position, and then the connecting rod 17 of the required model is taken down from the corresponding three-dimensional shelf 1 through the picking and placing mechanism 4.

The two first rollers 5 are relatively arranged on both sides of the track 2 to play a limiting role. The second roller 7 is arranged above the track 2 to play a walking drive role. The first roller 5 and the second roller 7 are both rotatably arranged on the base. The first motor 6 is fixedly installed on the base, and the first motor 6 is connected to the second roller 7 to drive the second roller 7 to rotate. The axis of the second roller 7 is perpendicular to the axis of the first roller 5. Limiting units 3 are fixedly provided at both ends of the track 2 to limit the position of the walking mechanism and prevent the walking mechanism from slipping off the track 2.

[0026] The pick-and-place mechanism 4 is fixedly arranged on the base, and the pick-and-place mechanism 4 includes a column 10, a vertical moving component, a sliding sleeve 12, a cargo platform 14 and a fork 16. The column 10 is vertically fixedly arranged on the base by welding. The sliding sleeve 12 is slidably sleeved on the column 10. The column 10 is equipped with a vertical moving component, and the sliding sleeve 12 is connected to the vertical moving component, so that the sliding sleeve 12 can be driven to reciprocate vertically by the vertical moving component. The sliding sleeve 12 is equipped with a transverse moving component, and the cargo platform 14 is connected to the sliding sleeve 12 through the transverse moving component. The cargo platform 14 can not only move vertically with the sliding sleeve 12, but also move horizontally relative to the sliding sleeve 12, so as to realize the picking and placing of connecting rods 17 of different heights and depths on the three-dimensional shelf 1, and the fork 16 is fixedly arranged on the cargo platform 14, so as to use the fork 16 to pull the connecting rod 17 out of the three-dimensional shelf 1.

The chain 9 passes around the sprocket and the guide wheel 11 on the second motor 8 in sequence, and the chain 9 is fixedly connected to the sleeve 12. The second motor 8 can drive the sleeve 12 to move vertically through the chain 9. In this embodiment, the cross-section of the column 10 is rectangular, and the sleeve 12 is a hollow rectangular tube structure to play a limiting role and prevent the sleeve 12 from rotating around the axis.

[0028] The lateral movement component includes a third motor 13 and a rack 15. The third motor 13 is fixedly arranged on the sliding sleeve 12, and the rack 15 is fixedly arranged at the bottom of the cargo platform 14. The output end of the third motor 13 is fixedly provided with a gear meshing with the rack. The lateral movement of the cargo platform 14 can be controlled by the cooperation between the gear and the rack 15. In order to improve the stability of the cargo platform 14, a support plate is fixedly arranged on one side of the sliding sleeve 12, and the cargo platform 14 is slidably arranged on the support plate. The support plate and the cargo platform 14 are also cooperated by a slide groove and a slider to ensure that the cargo platform 14 does not deflect when moving.

[0029] like Figure 3 As shown, the fork 16 is U-shaped as a whole, and a hook structure is fixedly provided at the end of the fork 16 close to the three-dimensional shelf 1. The U-shaped fork 16 reduces weight while increasing the contact range with the connecting rod 17, thereby ensuring the supporting stability of the connecting rod 17. The setting of the hook structure makes it easier to pull out and remove the connecting rod 17 from the corresponding limit groove and support frame.

[0030] Example 2 In another typical embodiment of the present invention, Figure 4-Figure 7As shown, a disconnector connecting rod storage and retrieval system is proposed, including: a three-dimensional shelf group and a retrieval device, the three-dimensional shelf 1 includes a plurality of vertical frames, a horizontal frame and a support frame, wherein the vertical frame is vertically fixed on the ground, and the horizontal frame is horizontally fixed on the vertical frame by welding, bolt connection, etc., and the vertical frame and the horizontal frame are combined to form the main structure of the three-dimensional shelf 1, and a plurality of support frames are evenly fixed on one side of the main structure obliquely upward to support the connecting rod 17, and the plurality of support frames are divided into a plurality of layers to improve space utilization. The support frames are at an angle of 2° with the horizontal plane, which can ensure that the connecting rod 17 will not automatically roll off the support frame while avoiding the connecting rods 17 from being stacked and squeezed together, thereby preventing the connecting rods 17 from being squeezed and deformed.

[0031] The picking and placing device includes a walking mechanism and a picking and placing mechanism 4. The picking and placing mechanism 4 is fixedly arranged on the walking mechanism, and the walking mechanism is arranged on the track 2, so that the picking and placing mechanism 4 is driven by the walking mechanism to move to the specified position, and then the connecting rod 17 of the required model is taken down from the corresponding three-dimensional shelf 1 through the picking and placing mechanism 4.

[0032] like Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, vertical frames 18 are fixedly provided on both sides of the three-dimensional shelf group, and tracks 2 are fixedly provided on the vertical frames 18 . Tracks 2 are parallel to the three-dimensional shelf 1 and are higher than the three-dimensional shelf 1 . A pick-and-place device is movably provided on the track 2 .

[0033] Specifically, the walking mechanism includes a frame 18, a first walking unit 19 and a second walking unit 20. The first walking unit 19 is a crane structure. Both ends of the first walking unit 19 are connected to the track 2 on the top of the frame 18. The second walking unit 20 is installed between the base and the first walking unit 19. A track is provided at the bottom of the first walking unit 19 and is connected to the base through the second walking unit 20, so that the base can move on the first walking unit 19. The moving directions of the first walking unit 19 and the second walking unit 20 are perpendicular, so that the picking and placing mechanism 4 can be driven to transfer between the three-dimensional shelves 1. Compared with setting the track 2 on the ground, the number of tracks 2 is effectively reduced, thereby reducing the cost of use.

[0034] The pick-and-place mechanism 4 is fixedly arranged at the bottom of the base, and the pick-and-place mechanism 4 includes a column 10, a vertical moving component, a sliding sleeve 12, a cargo platform 14 and a fork 16. The column 10 is fixedly arranged at the bottom of the base by welding. The sliding sleeve 12 is slidably sleeved on the column 10. The column 10 is equipped with a vertical moving component, and the sliding sleeve 12 is connected to the vertical moving component, so that the sliding sleeve 12 can be driven to reciprocate vertically by the vertical moving component. The sliding sleeve 12 is equipped with a transverse moving component, and the cargo platform 14 is connected to the sliding sleeve 12 through the transverse moving component. The cargo platform 14 can not only move vertically with the sliding sleeve 12, but also move horizontally relative to the sliding sleeve 12, so as to realize the picking and placing of connecting rods 17 of different heights and depths on the three-dimensional shelf 1, and the fork 16 is fixedly arranged on the cargo platform 14, so as to use the fork 16 to pull the connecting rod 17 out of the three-dimensional shelf 1.

[0035] Specifically, the vertical moving component includes a second motor 8, a chain 9 and a guide wheel 11, wherein the second motor 8 is fixedly arranged on the column 10, a sprocket is fixedly arranged at the output end of the second motor 8, and a guide wheel 11 is fixedly arranged at the bottom end of the column 10.

[0036] The lateral movement component includes a third motor 13 and a rack 15. The third motor 13 is fixedly arranged on the sliding sleeve 12, and the rack 15 is fixedly arranged on the top of the cargo platform 14. The output end of the third motor 13 is fixedly provided with a gear meshing with the rack.
