Description

Technical Field

[0001] The utility model relates to the technical field of special equipment detection, in particular to a safety protection device for special equipment detection. Background Art

[0002] Special equipment refers to eight categories of equipment involving life safety and greater risks, including boilers, pressure vessels (including gas cylinders), pressure pipelines, elevators, lifting machinery, passenger ropeways, large-scale amusement facilities, and special-purpose motor vehicles within factories (yards). In order to detect special equipment, different tools are required. In order to prevent the tools from falling during the detection process, it will affect the detection efficiency of the detection personnel and may injure other personnel.

[0003] Therefore, for a safety protection device for special equipment detection with the publication number CN218664828U, when in use, the anti-drop rope is pulled out through a hook. When the anti-drop rope is pulled out, it drives the winding wheel to rotate. After the anti-drop rope is pulled out to a certain applicable length, the pressure rod is pressed downward at this time, driving the nut to move downward. Through the threaded connection and cooperation between the nut and the ball screw, the ball screw is driven to rotate, driving the eccentric wheel to rotate, which can squeeze the moving clamping rod to move to the left. The moving clamping rod cooperates with the fixed clamping rod to clamp and fix the anti-drop rope. Here, by setting two rubber blocks, flexible clamping of the anti-drop rope can be realized, avoiding clamping the anti-drop rope damaged. At the same time, the rubber blocks have a large friction force, which can ensure the clamping stability of the anti-drop rope. Then, when the anti-drop rope is clamped and fixed, the pressure rod just moves below the clamping rod. At this time, the clamping rod moves and contacts the top of the pressure rod, blocking and limiting the upward movement of the pressure rod, maintaining the clamping and fixing of the moving clamping rod and the fixed clamping rod on the anti-drop rope.

[0004] However, in the prior art, the stability of the anti-drop rope is achieved through the friction force between two rubber blocks and the anti-drop rope. The method relying on friction force has deficiencies in use. For example, when the dropped tool is heavy, the acceleration generated during its dropping process combined with its own weight may exceed the friction force of the rubber blocks on the anti-drop rope, resulting in the risk of the anti-drop rope loosening. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the problems existing in the prior art, and to propose a safety protection device for special equipment detection.

[0006] To achieve the above object, the utility model adopts the following technical scheme: A safety protection device for special equipment detection, including a toolbox and a hook for connecting detection tools.

[0020] In order to more clearly understand the above-mentioned objects, features, and advantages of the present utility model, the present utility model will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0021] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0022] Such as Figures 1-4As shown in the figure, a safety protection device for special equipment detection includes a toolbox 1 and a hook 3 for connecting detection tools. A base 2 is fixedly connected to the outer bottom of the toolbox 1. A winding wheel 8 is installed inside the base 2. The structure of the winding wheel 8 is the same as that of the winding wheel in a safety protection device for special equipment detection with the publication number CN218664828U. Therefore, by pulling one end of the extension cloth 6, the winding wheel 8 can be forced to rotate to release the extension cloth 6. After releasing the extension cloth 6, by using the elastic rotation of the winding wheel 8 to drive the winding wheel 8 to rotate in the reverse direction, the released extension cloth 6 can be rewound on the winding wheel 8. The extension cloth 6 is wound around the winding wheel 8. A number of fixing holes 16 are provided on both sides of the surface of the extension cloth 6, and a flexible guide strip 7 is integrally formed and connected to the side of the extension cloth 6. The thickness of the provided flexible guide strip 7 is greater than the thickness of the extension cloth 6. One side of the two flexible guide strips 7 extends outside the base 2 and is used to install the hook 3. Therefore, by pulling the hook 3, the extension cloth 6 can be released. The extension cloth 6 is released by the rotation of the winding wheel 8. A fixing frame 10 sleeved on the extension cloth 6 is slidably connected to the inner bottom surface of the base 2. The part of the extension cloth 6 located in the fixing frame 10 is in a fully unfolded state. A lifting plate 9 is inserted into the inner bottom surface of the fixing frame 10. Columnar protrusions extending outward from the corners of the upper surface of the lifting plate 9 pass through the fixing holes 16 and the top edge of the fixing frame 10. During use, first adjust the position of the fixing frame 10 so that the columnar protrusions on the lifting plate 9 are aligned with the fixing holes 16 on the extension cloth 6. Therefore, by raising the lifting plate 9, the columnar protrusions on the lifting plate 9 can pass through the fixing holes 16 on the extension cloth 6 and then be inserted into the top edge of the fixing frame 10, so as to fix the position of the extension cloth 6.

[0023] In order to ensure that the part of the extension cloth 6 close to the winding wheel 8 is in a fully unfolded state: Two limiting frames 17 distributed along the pulling direction of the extension cloth 6 are fixedly connected to the inner side wall of the base 2. The two limiting frames 17 are sleeved on the two flexible guide strips 7. An arc-shaped rail 15 sleeved on the flexible guide strip 7 and extending outside the base 2 is fixedly connected to the limiting frame 17 far from the winding wheel 8. The two limiting frames 17 are distributed on both sides of the fixing frame 10. Therefore, by using the two limiting frames 17 to clamp the flexible guide strips 7 on both sides of the extension cloth 6, the extension cloth 6 can pass through the fixing frame 10 in a horizontally unfolded posture and enter and exit the winding wheel 8. Moreover, as shown in the figure, the sizes of the two openings on both sides of the provided arc-shaped rail 15 are different. By shortening the gap between the two flexible guide strips 7 near the connecting strip 13, it is convenient for personnel to twist the direction and angle of the hook 3 later.

[0024] In order to ensure that the connecting strip 13 will not be deformed due to the shortening of the distance between the two flexible guiding strips 7: the connecting strip 13 is fixedly connected to the hook 3, and the two ends of the side of the connecting strip 13 are hollowed out, and one end of the flexible guiding strip 7 is fixedly connected to a T-shaped rod 18 inserted in the hollow part of the connecting strip 13. When the gap between the free ends of the two flexible guiding strips 7 is shortened, the T-shaped rod 18 on the end face will be driven to slide in the hollow part of the connecting strip 13, thereby ensuring that the connecting strip 13 will not be deformed.

[0025] In order to drive the lifting plate 9 to move up and down: an electric push rod 12 is fixedly connected to the inner bottom surface of the fixing frame 10 , and the telescopic end of the electric push rod 12 on the fixing frame 10 is fixed to the bottom surface of the lifting plate 9 .

[0026] In order to ensure that the lifting plate 9 is aligned with the fixing holes 16 on the stretch cloth 6: a plurality of guide rails 11 penetrating the bottom edge of the side of the fixing frame 10 are fixedly connected to the inner bottom surface of the base 2, and one of the top edges of one of the guide rails 11 is also connected to the side of the fixing frame 10 through an electric push rod 12. By installing a camera on the fixing frame 10, the relative position of the fixing frame 10 and the fixing holes 16 on the stretch cloth 6 can be monitored in real time. In actual use, the electric push rod 12 on the guide rail 11 can be extended and retracted to realize the sliding of the fixing frame 10 along the surface of the plurality of guide rails 11, thereby adjusting the relative position of the lifting plate 9 and the fixing holes 16 on the stretch cloth 6.

[0027] To facilitate the placement of detection tools: a number of tool plates 4 are inserted into the tool box 1, and a number of inclined tool slots 5 are embedded and fixedly connected on the side of the tool plate 4 from top to bottom. The bottom of the tool slot 5 is hollowed out, and a blocking pin 14 is threadedly connected to the hollow part. The tool slot 5 can be used to store the detection tools at an angle, and the position of the blocking pin 14 can be adjusted by using the hollow part at the bottom of the tool slot 5. The installed blocking pin 14 can be used to realize the separation and storage of the tools placed in the tool slot 5.

[0028] Working principle: pull out the tool plate 4, and take the corresponding detection tool from the tool slot 5 at the corresponding position, pull the hook 3 to make the stretch cloth 6 slide in the fixing frame 10 and the limit frame 17, use the hook 3 to hook the detection tool in use, and the stretch cloth 6 passing through the fixing frame 10 is adjusted by the movement of the fixing frame 10, and then the lifting plate 9 is raised to make the columnar protrusion of the lifting plate 9 pass through the fixing hole 16 on the stretch cloth 6 and then inserted into the top edge of the fixing frame 10, so that the position of the stretch cloth 6 can be fixed.

[0029] The wiring diagram of the electric push rod 12 in the present invention belongs to the common knowledge in the field, and its working principle is a well-known technology. The model is selected according to the actual use, so the control method and wiring arrangement of the electric push rod 12 are not explained in detail.

[0030] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution content of the present utility model still fall within the protection scope of the technical solution of the present utility model.
