Description

Technical Field

[0001] This utility model relates to the field of automatic positioning structure technology, specifically a novel automatic positioning structure for a guide roller frame. Background Technology

[0002] Currently, the guide roller frame on the cable cart of existing pipeline inspection robots generally uses pin positioning. That is, after the guide roller frame is opened, a pin is inserted to support the bottom of the bracket. The guide roller frame refers to the metal structural frame on which these rollers are installed. This frame not only supports the rollers, but also bears the weight of the transmission cable.

[0003] The current limitations of the guide roller frame are mainly as follows: when opening the guide roller frame, positioning pins need to be inserted on both sides, which can easily lead to difficulties in installing the pins when the round holes are not aligned accurately; when retracting, the pins on both sides also need to be pulled out. Existing automatic positioning structures of this type generally do not facilitate convenient automatic positioning, which affects the labor intensity of manual workers, the practicality of automatic positioning, and the ease of cable release or rewinding. Utility Model Content

[0004] The purpose of this utility model is to provide a novel automatic positioning structure for guide roller frames, in order to solve the problems mentioned in the background art, such as the inconvenience of automatic positioning structures in automatically positioning, which affects the labor intensity of manual labor, the practicality of automatic positioning, and the inconvenience of automatic cable release or rewinding.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel automatic positioning structure for a guide roller frame, comprising a cable trolley and a roller support base. The cable trolley has roller support bases symmetrically mounted on its sidewalls. The roller support bases have indexing pins symmetrically arranged on their exteriors. Each indexing pin has a roller support arm on its exterior. Each roller support arm has a through hole on its surface, and a positioning hole below each through hole. A slot is installed between two sets of roller support arms. A roller body is mounted outside each roller support arm. A rotating shaft is movably mounted inside each roller support base, extending through the roller support base to its exterior. Each roller support base is movably connected to the roller support arm via the rotating shaft. Bolts are provided on the exterior of each roller support arm, threaded through the roller support arm and connected to the roller body. Stainless steel positioning posts are installed on the inner wall of each roller support base. A second sliding groove is provided on the top sidewall of each roller support arm, and a first sliding groove is provided on the sidewall of the roller support arm below the second sliding groove. Support posts are installed on the outer wall of each roller support base.

[0006] Preferably, a pin is movably mounted inside the support column, the pin extends through the support column to its outside, and a handle is mounted on the surface of the outer pin of the support column.

[0007] Preferably, each of the pins is fitted with a spring, and the side of the spring furthest from the pin is connected to the support column.

[0008] Preferably, a servo motor is installed inside the cable trolley, and a rotating shaft is installed at the output end of the servo motor.

[0009] Preferably, a small sprocket is fitted onto the surface of the rotating shaft, and a support shaft is movably mounted on the side wall of the cable trolley.

[0010] Preferably, a first sprocket is fitted onto the surface of the support shaft, and a movable shaft is movably installed on the side wall of the cable trolley away from the support shaft.

[0011] Preferably, a large sprocket is fitted onto the surface of the movable shaft, and a chain is fitted onto the surfaces of the small sprocket, the first sprocket, and the large sprocket.

[0012] Preferably, a cable drum is fitted on the side of the movable shaft away from the large sprocket, and three sets of auxiliary rollers are movably installed inside the cable trolley outside the cable drum.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the automatic positioning structure not only realizes the convenient automatic positioning of the automatic positioning structure, reducing the labor intensity of manual labor and improving the practicality of the automatic positioning structure, but also realizes the convenient release or rewinding of the cable, improving the convenience of the automatic positioning structure in releasing or rewinding the cable. (1) When using the new type of automatic positioning structure for the guide roller frame, the slot serves to collect the cable connector. The roller body is fixed by bolts passing through the roller support arm. When the roller body needs to be opened, the roller support arm is rotated 90 degrees. Under the movable support of the rotating shaft, the roller support arm drives the roller body to rotate 90 degrees around the rotating shaft. When the roller support arm rotates, it drives the second slide to rotate. Under the elastic support of the spring, the second slide makes elastic contact with the pin. When the roller support arm rotates to 90 degrees, the through hole on the surface of the roller support arm matches the pin. Under the elastic support of the spring, The pin is inserted into the through hole, which in turn allows the indexing pin to automatically insert into the through hole on the surface of the roller support arm, thus fixing the roller support arm in place. When retracting the roller body, the handle is gently pulled outward. Under the elastic support of the spring, the pin disengages from the through hole, allowing the roller support arm to rotate. Under the action of gravity, the roller support arm resets. After the roller support arm resets, the stainless steel positioning pin contacts the positioning hole to position it and prevent it from swinging left and right. This achieves convenient automatic positioning of the automatic locking structure, reduces manual labor intensity, and improves the practicality of the automatic positioning structure. (2) When it is necessary to release or rewind the cable, the servo motor drives the rotating shaft to rotate, the rotating shaft drives the small sprocket to rotate, and the chain meshes with the first sprocket and the large sprocket, so that the small sprocket drives the chain to rotate, the chain drives the first sprocket and the large sprocket to rotate, and the large sprocket drives the cable drum to rotate through the movable shaft to release or rewind the cable. The auxiliary roller plays the role of limiting the cable drum, realizing the automatic positioning structure to conveniently release or rewind the cable, which facilitates the sorting and organization of the cable and improves the convenience of the automatic positioning structure to release or rewind the cable.

Each part is movably mounted with a rotating shaft 7, which extends through the roller support base 2 to its outside. The roller support base 2 is movably connected to the roller support arm 3 through the rotating shaft 7. Bolts 8 are provided on the outside of the roller support arm 3, which are threaded through the roller support arm 3 and connected to the roller body 4. Stainless steel positioning posts 9 are installed on the inner wall of the roller support base 2. A second sliding groove 11 is provided on the top side wall of the roller support arm 3. A first sliding groove 10 is provided on the side wall of the roller support arm 3 below the second sliding groove 11. Support posts 23 are installed on the outer wall of the roller support base 2. A pin 21 is movably installed inside the support column 23. The pin 21 extends through the support column 23 to its outside. A handle 25 is installed on the surface of the external pin 21 of the support column 23. Springs 22 are fitted on the surface of each pin 21, and the side of each spring 22 away from the pin 21 is connected to the support column 23. When using the new guide roller frame automatic locking structure, the cable slot 5 serves to collect the cable connector. With the bolt 8 threadedly connected to the roller body 4, the roller body 4 is fixed by the bolt 8 passing through the roller support arm 3. When it is necessary to open the roller body 4, the roller support arm 3 is rotated 90 degrees. Under the movable support of the rotating shaft 7, the roller support arm 3 drives the roller body 4 to rotate 90 degrees around the rotating shaft 7. When the roller support arm 3 rotates, it drives the second slide groove 11 to rotate. Under the elastic support of the spring 22, the second slide groove 11 makes elastic contact with the pin 21. When the roller support arm 3 rotates to 90 degrees, the through hole 26 on the surface of the roller support arm 3 matches the pin 21. Under the elastic support of spring 22, pin 21 is inserted into the through hole 26, thereby automatically inserting indexing pin 6 into the through hole 26 on the surface of roller support arm 3, fixing roller support arm 3; when retracting roller body 4, handle 25 is gently pulled outward, and under the elastic support of spring 22, pin 21 is disengaged from through hole 26, allowing roller support arm 3 to rotate. Under the action of gravity, roller support arm 3 is reset. After roller support arm 3 is reset, stainless steel positioning post 9 contacts positioning hole 27 to position it and prevent it from swinging left and right. This realizes the convenient automatic positioning of the automatic locking structure, reduces the labor intensity of manual labor, and improves the practicality of the automatic positioning structure. The cable cart 1 is equipped with a servo motor 12, and the output end of the servo motor 12 is equipped with a rotating shaft 13. A small sprocket 14 is fitted onto the surface of the rotating shaft 13, and a support shaft 16 is movably mounted on the side wall of the cable cart 1. A first sprocket 17 is fitted onto the surface of the support shaft 16, and a movable shaft 18 is movably installed on the side wall of the cable trolley 1 away from the support shaft 16. The surface of the movable shaft 18 is fitted with a large sprocket 19, and the surface of the small sprocket 14, the first sprocket 17, and the large sprocket 19 is fitted with a chain 15. A cable drum 24 is fitted on the side of the movable shaft 18 away from the large sprocket 19. Three sets of auxiliary rollers 20 are movably installed inside the cable trolley 1 outside the cable drum 24. When it is necessary to release or rewind the cable, the servo motor 12 is turned on. With the support of the cable cart 1, the servo motor 12 drives the rotating shaft 13 to rotate. The rotating shaft 13 drives the small sprocket 14 to rotate. With the small sprocket 14 meshing with the chain 15, and the chain 15 meshing with the first sprocket 17 and the large sprocket 19, the support shaft 16 provides movable support for the first sprocket 17, and the movable shaft 18 provides movable support for the large sprocket 19. This causes the small sprocket 14 to drive the chain 15 to rotate, and the chain 15 to drive the first sprocket 17 and the large sprocket 19 to rotate. The large sprocket 19 drives the cable drum 24 to rotate through the movable shaft 18, thereby releasing or rewinding the cable. The auxiliary roller 20 serves to limit the cable drum 24, realizing the convenient release or rewinding of the cable by the automatic positioning structure. This facilitates the sorting and organization of the cable and improves the convenience of the automatic positioning structure for releasing or rewinding the cable.

[0018] Working principle: When using the new type of automatic positioning structure for the guide roller frame, the cable slot 5 serves to collect the cable connector. The roller body 4 is fixed by bolts 8 passing through the roller support arm 3. When the roller body 4 needs to be opened, the roller support arm 3 is rotated 90 degrees. Under the movable support of the rotating shaft 7, the roller support arm 3 drives the roller body 4 to rotate 90 degrees around the rotating shaft 7. When the roller support arm 3 rotates, it drives the second slide groove 11 to rotate. Under the elastic support of the spring 22, the second slide groove 11 makes elastic contact with the pin 21. When the roller support arm 3 rotates to 90 degrees, the through hole 26 on the surface of the roller support arm 3 matches the pin 21. Under the elastic support of the spring 22, the pin 21 is inserted into the through hole 26, thereby automatically inserting the indexing pin 6 into the through hole 26 on the surface of the roller support arm 3, fixing the roller support arm 3. When retracting the roller... When the drum body 4 is in operation, gently pull the handle 25 outward. Under the elastic support of the spring 22, the pin 21 disengages from the through hole 26, allowing the drum support arm 3 to rotate. Under the action of gravity, the drum support arm 3 resets. After the drum support arm 3 resets, the stainless steel positioning pin 9 contacts the positioning hole 27 to position it and prevent it from swinging left and right. When it is necessary to release or rewind the cable, the servo motor 12 drives the rotating shaft 13 to rotate. The rotating shaft 13 drives the small sprocket 14 to rotate. The chain 15 meshes with the first sprocket 17 and the large sprocket 19, causing the small sprocket 14 to drive the chain 15 to rotate. The chain 15 drives the first sprocket 17 and the large sprocket 19 to rotate. The large sprocket 19 drives the cable drum 24 to rotate through the movable shaft 18 to release or rewind the cable. The auxiliary roller 20 limits the cable drum 24 to complete the operation of the automatic positioning structure.
