[0037] As shown in Figure 2 and Figure 3 A truss robot maintenance Z-axis anti-falling device, comprising two limiting assemblies oppositely arranged on the movable seat 2 of the truss robot, the limiting assembly is used to limit the displacement of the vertical beam 3 of the truss robot along its length direction, and the limiting assembly comprises:

[0038] The fixed part 9 with a sliding groove is connected to the movable seat 2 of the truss robot at one end;

[0039] The clamping part 16 is slidably arranged in the sliding groove at one end, and the other end of the clamping part 16 is matched with the clamping groove 8 arranged on the surface of the vertical beam 3 of the truss robot, so as to prevent the vertical beam 3 of the truss robot from moving relative to the movable seat 2 of the truss robot;

[0040] The above technical scheme can prevent the vertical beam 3 from falling due to the failure of the gear and the rack 6. When the Z-axis assembly needs to be maintained, the clamping part 16 on the side of the fixed part 9 is pushed, so that the clamping part 16 slides along the sliding groove of the fixed part 9, and then one end of the clamping part 16 is inserted into the clamping groove 8 on the surface of the vertical beam 3. Through the mutual cooperation of the clamping part 16 and the clamping groove 8, the movement of the vertical beam 3 along its length direction can be limited, thereby effectively preventing the vertical beam 3 from falling due to the failure of the gear and the rack 6.

[0041] As shown in Figure 3 and Figure 4As shown, in the embodiment, the anti-falling device further comprises a first limiting structure for preventing the engagement member 16 from moving relative to the fixed member 9; specifically, the first limiting structure comprises: a limiting member 19 slidably connected to one end of the engagement member 16, the fixed member 9 is provided with a through slot 10 matched with the limiting member 19, the through slot 10 divides the sliding slot into a first sliding slot 14 and a second sliding slot 15, when the limiting member 19 is misaligned with the engagement member 16, the inner wall of the through slot 10 limits the front and back sides of the limiting member 19; a screw rod 18 connected to one end of the engagement member 16, the screw rod 18 is matched with a sliding hole 20 provided in the limiting member 19; a positioning nut 21 matched with the screw rod 18; each limiting member 19 is provided with at least two sliding holes 20, correspondingly, the screw rod 18 has at least two, and the limiting member 19 is provided with a first handle 22;

[0042] The above technical scheme can ensure that the engagement member 16 is fixed after being inserted into the clamping groove 8 of the vertical beam 3, when the engagement member 16 is inserted into the clamping groove 8 of the vertical beam 3, since the engagement member 16 is slidably arranged in the sliding slot of the fixed member 9, in order to prevent the engagement member 16 from loosening, the limiting member 19 needs to be pushed to make its sliding hole 20 slide along the screw rod 18, so that the limiting member 19 is misaligned with the engagement member 16, at this time, the limiting member 19 is attached to the two sides of the inner wall of the through slot 10, limiting the movement of the two sides of the limiting member 19, thereby preventing the movement of the engagement member 16, then the positioning nut 21 is connected with the screw rod 18, the limiting member 19 is locked by using the positioning nut 21, preventing the limiting member 19 from sliding, thereby completing the locking of the engagement member 16, when the engagement member 16 needs to be unlocked, the positioning nut 21 is unscrewed, the first handle 22 is held to pull the limiting member 19 to make it coincide with the engagement member 16, then the engagement member 16 can be driven to slide along the first sliding slot 14 and the second sliding slot 15 together with the limiting member 19, until the engagement member 16 is disengaged from the clamping groove 8 of the vertical beam 3.

[0043] As shown in Figure 4 and Figure 5 As shown in the embodiment, the first limiting structure further comprises: a fixed block 23 connected to one end of the engagement member 16, the fixed block 23 is slidably matched with an inner slot 24 provided in the limiting member 19; a spring 25 connected to one end of the fixed block 23, the other end of the spring 25 is connected to the inner wall of the inner slot 24, the spring 25 is used to keep the limiting member 19 aligned with the engagement member 16; a driving member 11 rotatably arranged in the through slot 10; a rotating shaft 12 connected to one end of the driving member 11, the other end of the rotating shaft 12 is connected with a second handle, the driving member 11 is a cam, rotating the driving member 11 around the rotating shaft 12 can drive the limiting member 19 to misalign with the engagement member 16, the rotating shaft 12 is rotatably matched with a rotating slot provided in the fixed member 9; a positioning slot 17 is provided on one side of the engagement member 16, when the driving member 11 enters the positioning slot 17, the movement of the engagement member 16 along the sliding slot is limited;

[0044] The above technical solution allows for convenient adjustment of the position of the limiting member 19 relative to the engaging member 16. When it is necessary for the limiting member 19 and the engaging member 16 to be misaligned, the second handle is gripped to rotate the rotating shaft 12. The rotating shaft 12 then rotates the driving member 11, which in turn pushes the limiting member 19 to slide relative to the engaging member 16, thereby misaligning the limiting member 19 and the engaging member 16. When it is necessary for the limiting member 19 and the engaging member 16 to be aligned, the driving member 11 and the limiting member 19 are rotated. After disengaging, under the elastic force of spring 25, the limiting member 19 resets and aligns with the engaging member 16. Pulling the first handle 22 causes the limiting member 19 and the engaging member 16 to slide along the first slide groove 14 and the second slide groove 15 until the positioning groove 17 of the engaging member 16 aligns with the through groove 10. Holding the second handle causes the rotating shaft 12 to rotate, which in turn causes the driving member 11 to rotate, so that the driving member 11 is embedded in the positioning groove 17. This allows the engaging member 16 to be limited after the vertical beam 3 is unlocked.

[0045] like Figure 5 As shown, in this embodiment, the first limiting structure further includes a second limiting structure for restricting the rotation of the rotating shaft 12; specifically, the second limiting structure includes an external thread provided on the surface of the rotating shaft 12; and a locking nut 13 that matches the external thread of the rotating shaft 12.

[0046] The above technical solution can limit the rotation of the drive component 11. In use, tighten the locking nut 13 to make it move around the external thread of the rotating shaft 12 until the locking nut 13 is in contact with the surface of the fixing component 9, thereby limiting the rotation of the drive component 11.

[0047] Working principle: When it is necessary to lock the vertical beam 3, unscrew the locking nut 13 to disengage it from the fixing part 9, grasp the second handle and rotate the drive part 11 to disengage it from the positioning groove 17, grasp the first handle 22 and push the locking part 16 on the side of the fixing part 9 so that the locking part 16 slides along the slide groove of the fixing part 9, thereby inserting one end of the locking part 16 into the groove 8 on the surface of the vertical beam 3. Through the cooperation of the locking part 16 and the groove 8, the movement of the vertical beam 3 along its length direction can be restricted, thereby effectively preventing the vertical beam 3 from falling due to the failure of the gear or rack 6. Then, grasp the second handle to drive the rotating shaft 12 to rotate, the rotating shaft 12 drives the drive part 11 to rotate, the drive part 11 pushes the limiting part 19 to slide relative to the locking part 16, thereby making the limiting part 19 and the locking part 16 misaligned. Use the positioning nut 21 to connect with the screw 18, use the positioning nut 21 to lock the limiting part 19 to prevent the limiting part 19 from sliding.

[0048] When it is needed to release the locking of the vertical beam 3, the positioning nut 21 is unscrewed to be disengaged from the limiting piece 19, under the elastic force of the spring 25, the limiting piece 19 is reset to be aligned with the clamping piece 16, the first handle 22 is pulled to drive the limiting piece 19 and the clamping piece 16 to slide along the first sliding groove 14 and the second sliding groove 15, until the positioning slot 17 of the clamping piece 16 is aligned with the through slot 10, the second handle is held to drive the rotating shaft 12 to rotate, the rotating shaft 12 drives the driving piece 11 to rotate, so that the driving piece 11 is embedded into the positioning slot 17, the clamping piece 16 can be limited after the vertical beam 3 is unlocked, the locking nut 13 is tightened to move around the external thread of the rotating shaft 12, until the locking nut 13 is attached to the surface of the fixing piece 9, the rotation of the driving piece 11 can be limited.
