[0031] The technical concept of the present application is to install an anti-fall safety protection device on the liftable handling equipment, and support the manipulator through a rotatable support arm during maintenance to prevent the manipulator from accidentally falling and injuring maintenance personnel.

[0032] Figures 1 to 4 An embodiment of the anti-fall safety protection device of the present application is schematically shown.

[0033] like Figures 1 to 4As shown, the present application discloses an anti-falling safety protection device 1, which is applied to a liftable handling device, and the liftable handling device includes: a lifting manipulator 2. The anti-falling safety protection device 1 of the embodiment of the present application includes:

[0034] The installation base plate 11 is fixedly installed on the liftable transport equipment.

[0035] The support arm 15 is rotatably disposed on the mounting base plate 11 . The support arm 15 can be rotated into the lifting path of the manipulator 2 to support the manipulator 2 to prevent the manipulator 2 from falling.

[0036] The locking mechanism is detachably connected to the support arm 15 and is used to lock the rotation position of the support arm 15 .

[0037] Through the above design, the embodiment of the present application can prevent the manipulator 2 from falling along the lifting path when repairing and maintaining the manipulator 2 by means of the supporting function of the support arm 15. Even if the manipulator 2 accidentally loses traction, it will not fall directly and injure the maintenance personnel, thereby improving the safety performance of the equipment and ensuring the safety of personnel. In addition, the present application also locks the rotation position of the support arm 15 through a locking mechanism, which can ensure that the anti-falling function of the support arm 15 is reliable, and at the same time does not interfere with the normal lifting operation of the manipulator 2 during daily production, so it is convenient and simple to use.

[0038] In some embodiments of the present application, Figures 2 to 4 As shown, the mounting base plate 11 is also provided with a first position sensor 14 and a second position sensor 12. The first position sensor 14 is provided at a first position where the support arm 15 is away from the lifting path of the manipulator 2, and is used to sense whether the support arm 15 has rotated to a first position (i.e., a closed state) that does not interfere with the movement of the manipulator 2. Figure 3 and Figure 4 The second position sensor 12 is disposed at the second position where the support arm 15 enters the lifting path of the manipulator 2, and is used to sense whether the support arm 15 has rotated to the second position (i.e., the open state) to prevent the manipulator 2 from falling. Figure 3 and Figure 4 By providing the first position sensor 14 and the second position sensor 12, the embodiment of the present application can reliably detect whether the support arm 15 has moved into position.

[0039] In some embodiments of the present application, the anti-fall safety protection device 1 of the present application also includes a controller, which is electrically connected to the first position sensor 14, the second position sensor 12 and the liftable handling equipment. The first position sensor 14 can enable the liftable handling equipment through the controller, that is, after the maintenance is completed, it is detected that the support arm 15 rotates back to the first position to generate an electrical signal, allowing the liftable handling equipment to resume production. The second position sensor 12 can disable the liftable handling equipment through the controller, that is, when the maintenance is in progress, it is detected that the support arm 15 rotates to the second position to generate an electrical signal, prohibiting the liftable handling equipment from running, thereby avoiding the manipulator 2 from being started by mistake due to reasons such as accidental touch and injuring the maintenance personnel. Among them, the controller is, for example, a single-chip microcomputer of various models such as 8051, and the controller receives the electrical signals of the first position sensor 14 and the second position sensor 12 through the interrupt function, and realizes the enabling and disabling of the liftable handling equipment according to the electrical signal. This part of the control technology is a technical means known to those skilled in the art, and will not be repeated here.

[0040] In some embodiments of the present application, Figures 2 to 4 As shown, the support arm 15 is provided with a sensing block 151 that cooperates with the first position sensor 14 and the second position sensor 12. The sensing block 151 makes the position sensor generate an electrical signal by approaching or blocking the position sensor, thereby detecting whether the support arm 15 moves into position. Among them, the first position sensor 14 and the second position sensor 12 can adopt common sensor types such as infrared ranging sensors or magnetic ranging sensors.

[0041] In some embodiments of the present application, Figures 2 to 4 As shown, the mounting base plate 11 is installed at the rear of the lifting path of the manipulator 2. The support arm 15 is parallel to the mounting base plate 11 and faces backward when in the first position, and is parallel to the mounting base plate 11 and faces forward when in the second position. The support arm 15 is located in the lifting path of the manipulator 2 when in the second position. Specifically, in the present embodiment, the mounting base plate 11 is fixedly mounted on the side of the lifting arm of the lifting and transporting equipment by bolts, and a rotating shaft seat 13 is provided at the front end of the mounting base plate 11 near the manipulator 2, and a rotating shaft is provided in the rotating shaft seat 13 to rotate the mounting support arm 15. When the support arm 15 is in the first position (i.e., the closed state), it faces backward and does not interfere with the lifting and lowering movement of the manipulator 2; when the support arm 15 is in the second position (i.e., the open state), it faces forward and enters the lifting path of the manipulator 2 to prevent the manipulator 2 from falling.

[0042] In some embodiments of the present application, Figures 2 to 4As shown, the locking mechanism includes a positioning bolt 17. A threaded through hole is provided on the support arm 15, and positioning threaded holes are provided on the mounting base plate 11 corresponding to the first position and the second position. After the positioning bolt 17 passes through the threaded through hole of the support arm 15, it cooperates with the positioning threaded hole to lock the support arm 15 to the first position or the second position, so as to ensure that the support arm 15 does not rotate at will and ensure its anti-fall function is reliable.

[0043] In some embodiments of the present application, Figures 2 to 4 As shown, the positioning bolt 17 is a hand-tightened bolt, and a star-shaped handle is provided at the end of the hand-tightened bolt to facilitate manual operation by the staff.

[0044] In some embodiments of the present application, Figures 2 to 4 As shown, the support arm 15 is a triangular frame structure with a right-angled side facing upward, and a plurality of reinforcing ribs 152 are arranged in the triangular frame structure. While using the frame structure to reduce the weight and material cost of the support arm 15, it is ensured that the support arm 15 has sufficient supporting strength.

[0045] In addition, in some embodiments of the present application, Figures 2 to 4 As shown, the support arm 15 is provided with a bending portion 153 near the rotation axis, the bending portion 153 is bent away from the manipulator 2, and the outer edge of the bending portion 153 is arc-shaped. Therefore, when the support arm 15 rotates to the second position (i.e., when it rotates to the lifting path of the manipulator 2), the surface of the support arm 15 forms a surface contact with the surface of the mounting base plate 11, and the surface support positioning of the mounting base plate 11 is obtained, making the support arm 15 less likely to shake and shift, thereby further ensuring that the support arm 15 reliably and stably supports the manipulator 2, making it convenient for the staff to repair and maintain the manipulator 2. In the embodiment of the present application, Figures 2 to 4 As shown, the second position sensor 12 is disposed above the support arm 15 to avoid the support arm 15 so that the support arm 15 can smoothly rotate to contact the surface of the mounting base plate 11 .

[0046] In some embodiments of the present application, Figures 2 to 4 As shown, a buffer pad 16 is disposed on the top surface of the support arm 15. The buffer pad 16 is used to contact the manipulator 2 to buffer the collision pressure. The buffer pad 16 is, for example, a rubber pad or a nylon pad.

[0047] refer to Figures 1 to 4 As shown, the working principle of the embodiment of the present application is described:

[0048] When the manipulator 2 needs to be repaired, the manipulator 2 is raised to the repair height, and the support arm 15 is manually rotated so that the buffer gasket 16 is located at the bottom of the manipulator 2. At this time, the support arm 15 is in the open state of safety protection, and the positioning bolt 17 is locked to lock the support arm 15. At this time, the second position sensor 12 detects that the support arm 15 is rotated into place and sends an electrical signal, so that the various components of the liftable handling equipment are in a shutdown maintenance state, and personnel can enter for maintenance. After the maintenance is completed, the support arm 15 is manually rotated to the closed state and the positioning bolt 17 is locked. The first position sensor 14 detects that the support arm 15 is in the closed state and sends an electrical signal, so that the various parts of the liftable handling equipment gradually resume working state.

[0049] Based on the above-mentioned anti-fall safety protection device 1, the present application also discloses a liftable transport equipment, which includes: a lifting-arranged manipulator 2 and an anti-fall safety protection device 1 as in any of the above embodiments, wherein the anti-fall safety protection device 1 is used to support the manipulator 2 to prevent it from falling, thereby protecting the safety of maintenance personnel.

[0050] In summary, the anti-fall safety protection device of the present application includes: a mounting base plate, the mounting base plate is fixedly mounted on the liftable handling equipment; a support arm, the support arm is rotatably arranged on the mounting base plate, the support arm can be rotated into the lifting path of the manipulator, and the manipulator is supported to prevent the manipulator from falling; a locking mechanism, the locking mechanism is detachably connected to the support arm, and is used to lock the rotation position of the support arm. Thus, the present application can prevent the manipulator from falling along the lifting path when repairing and maintaining the manipulator with the help of the supporting effect of the support arm. Even if the manipulator loses traction accidentally, it will not fall directly and injure the maintenance personnel, thereby improving the safety performance of the equipment and ensuring the safety of the personnel. Moreover, the present application also locks the rotation position of the support arm through the locking mechanism, which can ensure the reliability of the anti-fall function of the support arm, and at the same time does not interfere with the normal lifting operation of the manipulator in daily production. The operation is simple and the function is reliable.

[0051] In a preferred embodiment of the present application, the anti-fall safety protection device also includes a first position sensor and a second position sensor to detect the position of the support arm to enable or disable the liftable handling equipment, thereby preventing accidental operation of the robot arm and threatening the safety of the staff.

[0052] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
