Description

Technical Field

[0001] The utility model belongs to the technical field of transfer, and particularly relates to a transfer arm for ultra-thin fiber cement boards. Background Art

[0002] The transfer arm for ultra-thin fiber cement boards is a transfer device provided for ultra-thin fiber cement boards. Usually, the ultra-thin fiber cement boards are transferred from a carrier or the ultra-thin fiber cement boards on the ground are transferred to the carrier to achieve transfer. And for ultra-thin fiber cement boards with large flat surfaces, suction cups are used instead of traditional clamping jaws to increase the fixing effect on the ultra-thin fiber cement boards.

[0003] However, due to the inclination caused by the limitation of the carrier itself or the ground, the ultra-thin fiber cement boards are in an inclined state. When the suction cup falls vertically, it cannot form a perpendicular contact with the ultra-thin fiber cement board in a non-horizontal state, which is not conducive to adsorption. Summary of the Utility Model

[0004] Aiming at the problem that when the suction cup falls vertically in the prior art and cannot form a perpendicular contact with the ultra-thin fiber cement board in a non-horizontal state, which is not conducive to adsorption, the utility model provides a transfer arm for ultra-thin fiber cement boards, and the specific technical solutions are as follows:

[0005] The transfer arm for ultra-thin fiber cement boards includes a hydraulic push rod that can move along a vertical plane and a suction panel coaxially arranged at the output end of the hydraulic push rod. A floating ball is connected to the bottom end of the hydraulic push rod. The floating ball is in clearance fit with the suction panel. The center of the floating ball is on the axis of the hydraulic push rod. In the vertical projection plane, the center of the floating ball coincides with the suction panel. The suction panel can rotate around any horizontal axis passing through the center of the floating ball.

[0006] As a further technical solution of the utility model, a leveling panel is horizontally arranged on the hydraulic push rod. The leveling panel is spaced above the suction panel. An elastic member is arranged between the leveling panel and the suction panel. The elastic member has an elastic force. At least three groups of elastic members are evenly distributed circumferentially around the hydraulic push rod to force the suction panel to be in a horizontal state under normal conditions.

[0007] As a further technical solution of the utility model, the leveling panel is slidably connected to the hydraulic push rod. A boss is provided on the leveling panel. A locking bolt that abuts against the hydraulic push rod is radially inserted into the boss.

[0008] As a further technical solution of the present utility model, the elastic member includes a sleeve connected to the leveling panel and a pressing rod that abuts against the adsorption panel. The pressing rod is slidably connected to the sleeve, and a spring is connected between the pressing rod and the sleeve. The spring is in a compressed state and drives the pressing rod to abut against the adsorption panel.

[0009] As a further technical solution of the present utility model, the pressing rod has a tip, and the pressing rod is in point contact with the adsorption panel through the tip.

[0010] As a further technical solution of the present utility model, at least three rolling groups are arranged in the adsorption panel. At least three rolling groups are circumferentially distributed around the hydraulic push rod. The rolling group includes at least two sets of balls from top to bottom. The balls are rotatably arranged in the adsorption panel, and the balls are in contact with the floating ball. At least two sets of balls are distributed on the upper and lower sides of the center of the floating ball.

[0011] The beneficial effects of the present utility model are as follows:

[0012] In this application, a spherical connection is made between the adsorption part and the hydraulic rod. When the suction cup touches the cement board directly, the adsorption part can rotate around any horizontal axis passing through the center of the ball. In this way, the adsorption panel can adapt to the inclination of the cement board and tilt automatically, thereby compensating for the inclination of the cement board and making the suction cup still in perpendicular contact with the cement board.

Specific embodiments

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0021] In view of the prior art that when the suction cup falls vertically, it cannot form a vertical contact with the ultra-thin fiber cement board in a non-horizontal state, which is not conducive to adsorption; a spherical connection is made between the adsorption part and the hydraulic rod. When the suction cup touches the cement board directly, the adsorption part can rotate around any horizontal axis passing through the center of the ball, so as to tilt to compensate for the tilt of the cement board, so that the suction cup still makes a vertical contact with the cement board.

[0022] Figure 1 The overall structural schematic diagram of the transfer arm for the ultra-thin fiber cement board is shown; Figure 1In this case, the transfer arm of the ultra-thin fiber cement board includes a fixed disk 100, a rotating part 200 rotatably installed on the fixed disk 100, a driving part 300 installed on the rotating part 200, and a suction part 400 connected to the output end of the driving part 300. An output motor 210 is connected below the fixed disk 100, and a main shaft 220 is connected above the fixed disk 100. The output end of the output motor 210 passes through the fixed disk 100 and is connected to the main shaft 220. An extension arm 230 extends radially on the main shaft 220, and the driving part 300 is installed at the other end of the extension arm 230. When the output motor 210 is started, it can drive the main shaft 220 and the extension arm 230 to rotate, thereby driving the driving part 300 installed on the extension arm 230 to rotate synchronously. The driving part 300 includes a hydraulic cylinder 310 installed on the extension arm 230. The output end of the hydraulic cylinder 310 is connected to a hydraulic push rod 320 that passes through the extension arm 230. The suction part 400 is connected to the bottom of the hydraulic push rod 320. When it is necessary to adjust the height of the suction part 400, start the hydraulic cylinder 310, and the hydraulic push rod 320 and the suction part 400 can be driven to move up and down. When transferring the ultra-thin fiber cement board, the rotating part 200 drives the driving part 300 to rotate, so that the driving part 300 rotates to directly above the ultra-thin fiber cement board to be transferred. Then start the hydraulic cylinder 310 to drive the hydraulic push rod 320 and the suction part 400 to move down, so that the suction part 400 adsorbs the ultra-thin fiber cement board to be transferred. Drive the hydraulic push rod 320 to move up, and then drive the driving part 300 to rotate to the position where it needs to be released again through the rotating part 200. Then drive the suction part 400 to move down to place the ultra-thin fiber cement board to be transferred on the bearing part, so as to realize the transfer of the ultra-thin fiber cement board.

[0023] Figure 2 The structural schematic diagrams of the floating ball 510, the flatness finding plate 520, and the elastic member 530 are shown; Figure 3 It shows Figure 2Schematic diagram of the state structure; the adsorption part 400 includes an adsorption panel 410 and a number of suction cups 420 connected to the lower side of the adsorption panel 410. The number of suction cups 420 is circumferentially distributed around the hydraulic push rod 320. Under normal conditions, the adsorption panel 410 is in a horizontal state; the bottom end of the hydraulic push rod 320 is connected to a floating ball 510. The hydraulic push rod 320 is coaxially arranged with the adsorption panel 410. The floating ball 510 is in clearance fit with the adsorption panel 410. The center of the floating ball 510 is on the axis of the hydraulic push rod 320. In the vertical projection plane, the center of the floating ball 510 coincides with the adsorption panel 410. The adsorption panel 410 can rotate around any horizontal axis passing through the center of the floating ball 510; since in the vertical projection plane, the center of the floating ball 510 coincides with the adsorption panel 410, it can be known that the upper edge of the adsorption panel 410 is higher than the center of the floating ball 510, and the lower edge of the adsorption panel 410 is lower than the center of the floating ball 510. In this way, the center of the floating ball 510 is restricted within the adsorption panel 410, enabling the adsorption panel 410 and the floating ball 510 to allow relative movement but not fall off. In this way, the adsorption panel 410 can adapt to the inclination of the cement board and self-incline, thereby compensating for the inclination of the cement board and enabling the adsorption part 400 to still vertically adsorb the cement board; a leveling panel 520 is horizontally arranged on the hydraulic push rod 320. The leveling panel 520 is spaced above the adsorption panel 410. An elastic member 530 is arranged between the leveling panel 520 and the adsorption panel 410. The elastic member 530 has an elastic force. At least three groups of elastic members 530 are circumferentially and evenly distributed around the hydraulic push rod 320 to force the adsorption panel 410 to be in a horizontal state under normal conditions; since at least three groups of elastic elastic members 530 are distributed between the adsorption panel 410 and the leveling panel 520, the adsorption panel 410 can be parallel to the leveling panel 520 and in a horizontal state under normal conditions, so that the inclined cement board can automatically return to a horizontal state after leaving the ground, facilitating subsequent transportation; the leveling panel 520 is slidably connected to the hydraulic push rod 320. The leveling panel 520 has a boss 521. A locking bolt 522 that abuts against the hydraulic push rod 320 is radially inserted into the boss 521; by using the sliding connection between the leveling panel 520 and the hydraulic push rod 320, the distance between the leveling panel 520 and the adsorption panel 410 can be adjusted, thereby adjusting the elastic force of the elastic member 530 to be applicable to cement boards of different sizes, and the boss 521 can lock the slid leveling panel 520.

[0024] Figure 4The internal structure schematic diagram of the elastic member 530 is shown; the elastic member 530 includes a sleeve 531 connected to the flat panel 520 and a pressing rod 532 that abuts against the adsorption panel 410. The pressing rod 532 is slidably connected to the sleeve 531, and a spring 533 is connected between the pressing rod 532 and the sleeve 531. The spring 533 is in a compressed state and drives the pressing rod 532 to abut against the adsorption panel 410; the pressing rod 532 slides in the sleeve 531 to guide the deformation of the spring 533; the pressing rod 532 has a tip, and the pressing rod 532 is in point contact with the adsorption panel 410 through the tip; through the tip of the pressing rod 532, the contact area between the pressing rod 532 and the adsorption panel 410 is reduced to increase the accuracy in the horizontal state.

[0025] Figure 5 The structure schematic diagram of the connection between the adsorption panel 410 and the floating ball 510 is shown; at least three sets of rolling groups are arranged in the adsorption panel 410, and at least three sets of rolling groups are circumferentially distributed around the hydraulic push rod 320. The rolling group includes at least two sets of balls 411 from top to bottom. The balls 411 are rotatably arranged in the adsorption panel 410 and are in contact with the floating ball 510. At least two sets of balls 411 are distributed on the upper and lower sides of the center of the floating ball 510; the adsorption panel 410 can be indirectly in contact with the floating ball 510 through the balls 411, changing the sliding friction into rolling friction, and at least two sets of balls 411 distributed at intervals can form a supporting surface that wraps the center of the ball to ensure the supporting effect.

[0026] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
