Description

TECHNICAL FIELD

[0001] The utility model relates to anchor point device, concretely relates to a magnetic material surface magnetic attachment type anchor point device. BACKGROUND

[0002] At present, when carrying out the rust removal or spraying work on the very high vertical work surface, such as the ship shell surface and the metal chimney surface, the workers usually adopt the manual rust removal or spraying equipment to climb and work, the work danger is very high, and the working strength of the workers is also very big. Therefore, the industry starts to study the work of replacing the manual work with the wall-climbing robot matched with the rust removal or spraying equipment. The wall-climbing robot can be firmly adsorbed on the work surface through the mutual attraction between the permanent magnet and the magnetic material of the work surface. However, if an accident occurs, the permanent magnet is powered off and the safety device is not started, the robot also has a certain risk of falling. Therefore, the safety rope needs to be hung outside the robot to ensure the work safety. The anchor point needs to be fixed. The existing anchor point device is mostly installed and fixed by inserting into the work surface. The ship shell surface is mostly composed of a plurality of planar steel plates or small-curvature curved steel plates spliced together. The gap between the steel plates is very small, and the anchor point cannot be set by the insertion method. The metal chimney is mostly cylindrical, and the surface is smooth, so the anchor point cannot be set. If the anchor point needs to be set, the ship shell or the chimney surface needs to be damaged. Therefore, at present, the large lifting equipment is mostly used as the anchor point. The safety rope is hung on the telescopic arm of the large lifting equipment to ensure the safety of the personnel. However, the rental cost of the large lifting equipment is high, and the spraying time is long, which will greatly increase the operation cost. CONTENT OF THE UTILITY MODEL

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0028] like Figures 1-5 As shown, the magnetic anchor point device for magnetic material surface of this utility model includes a frame 1 and a motor mounting frame 21, with the motor mounting frame 21 located inside the frame 1.

[0029] A power motor 2 is mounted on the top of the motor mounting bracket 21. The output shaft of the power motor 2 is connected to the lead screw 5, providing power for the rotation of the lead screw 5. To limit the motor mounting bracket 21, two limit servos 3 are also provided, located at both ends of the motor mounting bracket 21 and mounted on the top of the frame 1. A T-shaped limit rod 4 is connected to the output shaft of each of the two limit servos 3. The T-shaped limit rod includes a vertical rod and a horizontal rod at one end of the vertical rod. The middle of the horizontal rod is connected to the end of the vertical rod, and their axes are perpendicular to each other. The vertical rod is connected to the output shaft of the limit servo 3.

[0030] A connecting lug 8 is connected to each end of the motor mounting bracket 21, and a locking hole is opened through the connecting lug 8 in the vertical direction. The shape of the locking hole is adapted to the shape of the horizontal bar. After the T-shaped limit rod 4 passes through the locking hole, its horizontal bar abuts against the bottom of the connecting lug 8. During normal operation, the axis of the horizontal bar is perpendicular to the length extension direction of the locking hole. This makes it convenient for the limit servo 3 to determine the rotation angle. When unlocking is required, the limit servo 9 rotates 90°, and the T-shaped limit rod 4 can be disengaged from the locking hole, unlocking the entire motor mounting bracket 21.

[0031] The motor mounting bracket 21 needs to slide vertically to transport the permanent magnet 7 installed at its bottom to the vertical working surface. Therefore, slide rails 6 are provided vertically on the inner sidewalls at both ends of the frame 1. Two connecting ears 8 slide in cooperation with the slide rails 6 respectively. The slide rails provide sliding guidance for the motor mounting bracket 21.

[0032] Connecting seats are provided at both ends inside the motor mounting bracket 21. Each connecting seat has a through hole in the center along the vertical direction. A guide rod 13 is provided in each through hole, and the top end of the guide rod 13 is connected to the top of the frame 1. There are two springs 11, which are arranged vertically and respectively sleeved on the two guide rods 13. The guide rods 13 provide motion guidance for the springs 11. One end of the spring 11 is connected to the top of the frame 1, and the other end is connected to the connecting seat. When the limit servo 3 limits the motor mounting bracket 21, the spring 11 is in a compressed state, accumulating elastic potential energy.

[0033] A hanging pulley 12 is connected to the motor mounting bracket 21 via a bracket. It serves as a fixing structure for hanging a safety rope. The hanging pulley 12 is located at one end of the frame 1 and is fixed to the bracket with bolts. This allows for the replacement of different fixing structures according to different situations, thereby improving the applicability of the device.

[0034] Only by permanent magnet 7 adsorption fixed, if the vertical work surface smooth, may produce slip, so need to increase the friction when adsorption, so also provided with friction plate mounting frame 9 and friction plate 10. Friction plate mounting frame 9 includes nut mounting frame 91 and guide frame 92, nut mounting frame 91 is located in motor mounting frame 21, the screw nut is installed on it, the screw rod 5 is screwed in the screw nut, the both ends of nut mounting frame 91 extend motor mounting frame 21 and are connected with guide frame 92, friction plate 10 is located at the bottom of permanent magnet 7 and is connected with the bottom end of guide frame 92, friction plate 10 is generally engraved with anti-skid lines, for increasing the friction when magnetic adsorption.

[0035] In order to ensure that the screw rod 5 rotates, the friction plate mounting frame 9 moves along the vertical direction, the guide frame 92 is also slidingly connected with the slide rail 6, and the guide frame 92 provides movement guide for the friction plate mounting frame 9. In order to reduce the overall weight, the weight-reducing holes are formed in the nut mounting frame 91 and the guide frame 92.

[0036] In use, the axis direction of the screw rod 5 is perpendicular to the vertical work surface, at this time, the limit rudder 3 is in the locked state, that is, the horizontal rod abuts against the bottom of the connecting lug 8, at this time, the power motor 2 drives the screw rod 5 to rotate, and the friction plate 10 is pressed and sent to the vertical work surface to abut against the vertical work surface. Then, the limit rudder 3 drives the T-shaped limiting rod 4 to rotate, so that the T-shaped limiting rod 4 is out of the self-locking hole, and the power motor 2 is reversed. Because of the existence of the magnetic force of the permanent magnet 7 and the elastic force of the spring 11, when the power motor 2 is reversed, the motor mounting frame 21 is pulled to the vertical work surface until the permanent magnet 7 abuts against the friction plate 10. At this time, the whole module is adsorbed on the vertical work surface through the magnetic force, and a magnetic attachment type anchor point is formed. Then, the safety rope can be hung by using the hanging pulley 12.

[0037] The above-described embodiments are merely used to describe specific implementation manners of the present application, and are not used to limit the scope of the present application. Without departing from the design spirit of the present application, various modifications and improvements made by those skilled in the art to the technical scheme of the present application shall fall within the protection scope of the present application.
