Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of high-altitude transportation equipment structures, in particular to a rotating oil cylinder and guardrail connection structure with simple structure, high connection strength, stable rotation effect and high safety performance. Background Art
[0002] As we all know, high-altitude transportation equipment generally moves the guardrail by a mechanical arm. The mechanical arm transports the guardrail to the position where work is required, and then drives the guardrail to rotate through the rotating cylinder connected between the end of the mechanical arm and the guardrail, and then rotates the guardrail to a position convenient for work. The cylinder barrel of the rotating cylinder is connected to the mechanical arm, and the output end of the rotating cylinder is connected to the guardrail. Because goods or operating personnel are transported on the guardrail, the overall weight of the guardrail is pressed on the output shaft end of the rotating cylinder, and the output end of the rotating cylinder is connected to the guardrail through a locking bolt. Moreover, the flange thickness of the output end of the rotating cylinder is small, and the locking distance between it and the bolt connection is very small. The locking bolt is easy to loosen, which will cause low connection strength, unstable rotation, and low safety performance between the guardrail and the output end of the rotating cylinder. Summary of the Invention
[0003] The purpose of the utility model is to solve the deficiencies of the above-mentioned prior art and to provide a rotating oil cylinder and guardrail connection structure with a simple structure, high connection strength, stable rotation effect and high safety performance.

The hook of the guardrail is clamped on the vertical plate at the clamping groove position. When the mechanical arm drives the rotating cylinder to lift the guardrail, the hook is hooked on the vertical plate at the clamping groove position.
[0009] A positioning plate is fixed on the vertical plate on the inner side of the card slot of the utility model. The positioning plate is vertically connected to the vertical plate. The card hook is positioned laterally by the positioning plate to ensure that the guardrail and the vertical plate are tightly positioned without shaking.
[0010] The back plane of the guardrail described in the utility model is parallel to the axis of the dovetail chute, ensuring that the guardrail is subjected to the same torsion when rotating left and right, thereby ensuring the strength and stability of the connection between the dovetail chute and the dovetail boss.

[0015] The present invention is further described below with reference to the accompanying drawings:
[0016] As shown in the accompanying drawings, a rotating cylinder and guardrail connection structure is provided with a rotating cylinder 1 and a guardrail 2, characterized in that the output shafts at the upper and lower ends of the rotating cylinder 1 are fixedly connected to the upper flange 3 and the lower flange 4, respectively, and the upper flange 3 and the lower flange 4 are respectively connected to the upper connecting plate 5 and the lower connecting plate 6 via locking bolts, wherein the upper flange 3 and the upper connecting plate 5 are clamped together via a dovetail groove 7 and a dovetail boss 8, and the upper connecting plate 5 and the lower connecting plate 6 are respectively connected to the guardrail 2.
[0017] Furthermore, a dovetail groove 7 is provided on the upper flange 3 at the upper end of the rotary cylinder 1 , and a dovetail boss 8 cooperating with the dovetail groove 7 is provided at the lower end of the connecting plate, and the dovetail boss 8 is engaged with the dovetail groove 7 .
[0018] Furthermore, a connecting boss 9 is provided on the cylinder wall of the rotating cylinder 1, and a connecting hole 10 is provided on the connecting boss 9. A connecting bolt is provided in the connecting hole 10, and the connecting bolt passes through the connecting hole 10 of the connecting boss 9 to connect to the robotic arm, and the rotating cylinder 1 is connected to the robotic arm through the connecting boss 9.
[0019] Furthermore, the ends of the upper connecting plate 5 and the lower connecting plate 6 are connected through a vertical plate 11, and a slot 12 is provided on the left and right sides of the vertical plate 11 respectively. A hook 13 is provided on the back of the guardrail 2, and the hook slot of the hook 13 faces downward. The position of the hook 13 corresponds to the position of the slot 12 of the vertical plate 11. The hook of the guardrail 2 is hooked on the vertical plate 11 at the slot 12 position. When the robotic arm drives the rotating cylinder 1 to lift the guardrail 2, the hook 13 is hooked on the vertical plate 11 at the slot 12 position.
[0020] Two slots 12 are respectively provided on the left and right sides of the vertical plate 11 , and two hooks 13 are correspondingly provided on the left and right sides of the back of the guardrail 2 to ensure the stability of the guardrail 2 and the vertical plate 11 after connection.
[0021] Furthermore, a positioning plate 14 is fixed on the vertical plate 11 on the inner side of the slot 12. The positioning plate 14 is vertically connected to the vertical plate 11. The positioning plate 14 is used to laterally position the hook 13 to ensure that the guardrail 2 is tightly positioned with the vertical plate 11 without shaking.
[0022] Furthermore, the back plane of the guardrail 2 is parallel to the axis of the dovetail chute 7, ensuring that the guardrail 2 is subjected to the same torque when rotating left and right, thereby ensuring the strength and stability of the connection between the dovetail chute 7 and the dovetail boss 8.
[0023] Furthermore, reinforcing ribs 15 are respectively provided on the left and right sides above the upper connecting plate 5 and on the left and right sides below the lower connecting plate 6. The reinforcing ribs 15 are respectively vertically connected to the upper connecting plate 5 or the lower connecting plate 6, thereby increasing the connection strength between the upper connecting plate 5 and the lower connecting plate 6.
[0024] When the utility model is manufactured, the back of the guardrail 2 is integrally connected to the corresponding hook 13, and the vertical plate 11 is connected to the upper connecting plate 5, the lower connecting plate 6, and the positioning plate 14 respectively. A dovetail boss 8 is provided below the upper connecting plate 5, and a dovetail groove is provided on the upper flange 3 connected to the upper end of the output shaft of the rotating oil cylinder 1. The upper connecting plate 5 is connected to the upper flange 3 through the dovetail groove and the dovetail boss 8, and then the upper connecting plate 5 and the lower connecting plate 6 are connected to the upper flange 3 and the lower flange 4 of the output shaft of the rotating oil cylinder 1 by the locking bolts. After the connection, the vertical plate 11 is driven to move to the back of the guardrail 2 by the movement of the mechanical arm, and the hook 13 is fixed. The hook is in the slot 12 position, thereby realizing the connection between the robot arm, the rotating cylinder 1 and the guardrail 2. Since the back plane of the guardrail 2 is parallel to the axis of the dovetail slide 7, the guardrail 2 is subjected to the same torsion when rotating left and right, ensuring the strength and stability of the connection between the dovetail slide 7 and the dovetail boss 8, thereby also increasing the stability of the connection between the output shaft of the rotating cylinder 1 and the upper connecting plate 5 and the lower connecting plate 6, so that the rotation of the entire structure is stable, the connection strength is high, and the safety performance is also high. Due to the adoption of the above structure, the utility model has the advantages of simple structure, high connection strength, stable rotation effect, and high safety performance.
