Description

Technical Field

[0001] This utility model relates to the field of park safety operation technology, specifically a park safety operation device. Background Technology

[0002] Park safety operation devices refer to a series of equipment and systems used to ensure the safety of workers in the park. They prevent people or objects from entering the dangerous area by setting up surrounding fences or passageway protective devices, thereby achieving distance protection.

[0003] Traditional safety operation devices in industrial parks have height limitations on the guardrail itself. As a result, when the surrounding area is modified and the height of the guardrail is reduced compared to the surrounding area, it affects the stable use of the guardrail. In addition, after the traditional guardrail is erected, the guardrail itself is easily affected by the surrounding environment, which can easily cause the guardrail to shift position, thereby affecting the stable installation of the device. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a safety operation device for industrial parks to solve the problems mentioned in the background.

[0005] This utility model provides the following technical solution: a safety operation device for a park, including a guardrail, an adjustable railing slidably connected to the inner wall of the guardrail, a fixed frame fixedly mounted on the side of the guardrail, a cone sleeve slidably sleeved on the inner wall of the fixed frame, a circular plate slidably sleeved on the inner wall of the cone, a conical rod fixedly mounted on the bottom of the circular plate, a cylindrical cylinder fixedly sleeved on the inner wall of the cone near the bottom, a fixed rod slidably sleeved on the inner wall of the cylindrical cylinder, a positioning wheel rotatably sleeved on the inner wall of the guardrail, a threaded rod fixedly mounted on the top of the positioning wheel, and the outer edge of the threaded rod being threadedly connected to the inner wall of the adjustable railing.

[0009] As a preferred embodiment of this utility model, the outer edge of the positioning wheel is provided with a positioning groove, and the shape and size of the concave surface of the positioning groove are adapted to the shape and size of the convex surface of the positioning rod.

[0010] As a preferred embodiment of this utility model, auxiliary rods are fixedly mounted on the top of both sides of the guardrail, and the outer edges of the two auxiliary rods are slidably sleeved with the inner wall of the adjustable railing.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The safety operation device in this park uses a cone and a cone rod in combination. The adjusting rod is moved down, which causes the bottom of the limiting plate to overlap with the top of the cone. The limiting plate then pushes the cone down, assisting the cone to connect with the ground. The adjusting rod is then rotated and moved down, which helps the outer edge of the adjusting rod to move down through the inner wall of the limiting groove. The bottom of the cone rod then pushes the protruding rod and the square plate to move, which in turn helps the outer edge of the fixed rod to slide within the inner wall of the cylinder. The adjusting rod is then rotated again, so that when the top of the limiting plate is limited to the top of the inner wall of the cone, the outer edge of the fixed rod is stably limited with the ground.

[0013] 2. The safety operation device in this park uses a positioning wheel and a threaded rod in combination. The positioning wheel drives the threaded rod to rotate, and the threaded rod drives the adjustment bar to adjust its height. An auxiliary rod is used to help the adjustment bar stabilize during height adjustment. A spring pushes the positioning rod to move in the inner wall of the positioning cylinder, which helps the convex surface of the positioning rod to fit with the concave surface of the positioning groove, thereby helping the adjustment bar to limit its height.

Through the cooperation of the cone 4 and the fixed frame 3, the outer edge of the cone 4 slides in the inner wall of the fixed frame 3, thereby assisting the outer edge of the bottom of the cone 4 to align with the ground. Through the cooperation of the positioning wheel 17 and the threaded rod 18, the positioning wheel 17 drives the threaded rod 18 to rotate, thereby using the threaded rod 18 to drive the adjustable railing 2 to adjust its height.

[0023] In a preferred embodiment, a tension spring 5 is fixedly connected to the bottom of the cone 4, and the bottom of the tension spring 5 is fixedly connected to the top of the circular plate 6. A protruding rod 10 is fixedly mounted on the side of the fixing rod 9, and a square plate 11 is fixedly sleeved on the outer edge of the protruding rod 10. A spring 12 is fixedly connected to the side of the square plate 11, and the end of the spring 12 away from the square plate 11 is fixedly connected to the inner wall of the cone 4. Through the cooperation of the tension spring 5 and the circular plate 6, the tension spring 5 pulls the circular plate 6 to move upward and reset. Through the cooperation of the protruding rod 10 and the square plate 11, when the spring 12 pushes the square plate 11 to move, the square plate 11 drives the fixing rod 9 to slide in the inner wall of the cylinder 8.

[0024] In a preferred embodiment, a limiting groove 16 is formed at the top of the cone 4, and a round rod 13 is fixedly mounted on the top of the circular plate 6. The top of the round rod 13 is rotatably connected to a limiting plate 14, and the shape and size of the outer edge of the limiting plate 14 are adapted to the shape and size of the inner wall of the limiting groove 16. An adjusting rod 15 is fixedly mounted on the top of the limiting plate 14. Through the cooperation of the round rod 13 and the limiting plate 14, when the limiting plate 14 slides in the inner wall of the limiting groove 16 for position adjustment, the limiting plate 14 drives the circular plate 6 and the cone 7 to adjust their positions through the round rod 13.

[0025] In a preferred embodiment, a positioning cylinder 20 is fixedly mounted on the inner wall of the guardrail 1. A spring 21 is fixedly connected to the inner wall of the positioning cylinder 20, and a positioning rod 22 is fixedly connected to the end of the spring 21 away from the inner wall of the positioning cylinder 20. The outer edge of the positioning rod 22 is slidably sleeved with the inner wall of the positioning cylinder 20. Through the cooperation of the spring 21 and the positioning rod 22, the spring 21 pushes the positioning rod 22 to move in the inner wall of the positioning cylinder 20, and then the outer edge of the positioning rod 22 slides in the inner wall of the positioning cylinder 20.

[0026] In a preferred embodiment, a positioning groove 23 is provided on the outer edge of the positioning wheel 17, and the shape and size of the concave surface of the positioning groove 23 are adapted to the shape and size of the convex surface of the positioning rod 22. Through the cooperation of the positioning groove 23 and the positioning rod 22, when the spring 21 pushes the positioning rod 22 to move, the convex surface of the positioning rod 22 fits against the concave surface of the positioning groove 23, thereby assisting the positioning wheel 17 to be stably limited.

[0027] In a preferred embodiment, auxiliary rods 19 are fixedly mounted on the top of both sides of the guardrail 1, and the outer edges of the two auxiliary rods 19 are slidably sleeved with the inner wall of the adjusting rail 2. By adding the auxiliary rods 19, the two auxiliary rods 19 are used to further assist the adjusting rail 2 in stabilizing the height adjustment.

[0028] Working principle: When the device is in use, the adjusting rod 15 is moved down, thereby causing the bottom of the limiting plate 14 to overlap with the top of the cone 4. The limiting plate 14 then pushes the cone 4 down, assisting the cone 4 to connect with the ground. The adjusting rod 15 is then rotated and moved down, allowing its outer edge to move down through the inner wall of the limiting groove 16. This, in turn, pushes the protruding rod 10 and the square plate 11 to move, assisting the outer edge of the fixing rod 9 to slide within the inner wall of the cylinder 8. Finally, the adjusting rod is rotated again. 15. Thus, when the top of the limiting plate 14 is limited to the top of the inner wall of the cone 4, the outer edge of the fixing rod 9 is stably limited to the ground. The positioning wheel 17 drives the threaded rod 18 to rotate, and the threaded rod 18 drives the adjusting bar 2 to adjust the height. The auxiliary rod 19 assists the adjusting bar 2 to adjust the height stably. The spring 21 pushes the positioning rod 22 to move in the inner wall of the positioning cylinder 20, thereby assisting the convex surface of the positioning rod 22 to fit with the concave surface of the positioning groove 23, thereby assisting the adjusting bar 2 to limit the height.
