[0002] Elevator guide rails are elevator components composed of steel rails and connecting plates. They are divided into car guide rails and counterweight guide rails. Elevator guide rails need to be tested for surface flatness after production. Any error or unevenness in the elevator guide rails will cause the running elevator to swing or vibrate when passing through this part, affecting the comfort, service life and even safety of the elevator.

[0067] like Figure 1-Figure 14 As shown, the workbench 1 is provided with a touch control unit 73, and the touch control unit 73 is electrically connected to the detection motor 72, the lifting electric push rod 65, the electromagnet 28, the vertical telescopic rod 54, the adjustment motor 63, and the clamping motor 77 respectively. The touch control unit 73 is a prior art and can adopt a touch screen commonly used in the prior art, which will not be repeated here.

[0068] The upper wall of the lifting plate 66 and the end of the detection probe 16 of the flatness detection marking device 7 on the side wall of the bottom rod 53 are at the same level.

[0069] like Figure 11-Figure 14 As shown, a C-shaped sleeve 79 is clamped on the connecting rod 21, and the C-shaped sleeve 79 is clamped between the detection probe 16 and the first cylinder 14. The C-shaped sleeve 79 can limit the detection probe 16 to prevent the detection probe 16 from driving the connecting rod 21 to move. The opening side of the C-shaped sleeve 79 can be deformed, and a gripping portion 80 is provided on the side of the C-shaped sleeve 79 away from the opening.

[0070] When in use, first, the elevator guide rail 15 is passed through the adjustable rectangular frame 6 and placed on the workbench 1. In the initial state, the lifting electric push rod 65 is in a retracted state, and a C-shaped sleeve 79 is installed between the detection probe 16 of each flatness detection mark device 7 and the first oil cylinder 14. At this time, the detection probe 16 of the flatness detection mark device 7 cannot push the active piston 20 to move toward the second oil cylinder 30, and the electromagnet 28 is in a power-off state, so the active piston 20 is in the middle of the first oil cylinder 14 and will not move. The upper wall height of the lifting plate 66 is lower than the upper wall of the workbench 1. At this time, the elevator guide rail 15 can be easily passed through the adjustable rectangular frame 6 and placed on the workbench 1. When the elevator guide rail 15 is completely placed When the two ends of the workbench 1 are located directly above the lifting plate 66, at this time, the clamping motor 77 is controlled to drive the two-way screw rod 75 to rotate, and the two-way screw rod 75 drives the clamping slider 76 to move toward each other along the clamping slide groove 74, and the clamping slider 76 drives the vertical clamping plate 78 to move toward each other and close to the elevator guide rail 15. When the vertical clamping plate 78 is tightly fitted with both sides of the elevator guide rail 15, the clamping motor 77 is controlled to stop working. At this time, the elevator guide rail 15 is tightly clamped in the middle of the lifting plate 66, and the vertical clamping plates 78 moving toward each other drive the elevator guide rail 15 to move to the middle of the adjustable rectangular frame 6, and then the lifting electric push rods 65 at both ends of the workbench 1 are controlled to extend at the same time to drive the lifting plate 66 to move up, and the lifting plates 66 at both ends of the workbench 1 It moves up close to the bottom wall of the elevator guide rail 15 and drives the elevator guide rail 15 to move up and away from the workbench 1. At the same time, the lifting plate 66 drives the linear moving mechanism 3 and the multi-directional detection data collection mechanism 4 arranged on the linear moving mechanism 3 to move synchronously. When the lifting plate 66 is in contact with the bottom wall of the elevator guide rail 15, the end of the detection probe 16 of the flatness detection marking device 7 of the side wall of the bottom rod 53 and the detection head of the micrometer 9 are also in contact with the bottom wall of the elevator guide rail 15. When the upper wall of the elevator guide rail 15 is in contact with the upper bottom wall of the door frame 5, the lifting electric push rod 65 is controlled to stop extending. At this time, the elevator guide rail 15 is tightly clamped between the lifting plate 66 and the door frame 5 and the two vertical clamping plates 78. Then the adjustable rectangular frame 6 is adjusted. The vertical telescopic rod 54 is controlled to contract to drive the top rod 55 to move downward, and the top rod 55 drives the detection probe 16 of the flatness detection mark device 7 of the side wall of the top rod 55 and the detection head of the micrometer 9 to approach the upper wall of the elevator guide rail 15. When the detection probe 16 of the flatness detection mark device 7 of the side wall of the top rod 55 is tightly fitted with the upper wall of the elevator guide rail 15, the vertical telescopic rod 54 is controlled to stop contracting, and then the adjustment motor 63 is started. The adjustment motor 63 drives the bidirectional screw rod 61 to rotate, and the bidirectional screw rod 61 drives the adjustment slider 62 to slide along the adjustment slide groove 60 to approach each other, thereby adjusting the distance between the two groups of vertical telescopic rods 54. The vertical telescopic rod 54 drives the side wall flatness detection mark device 7 to move toward each other and approach the two side walls of the elevator guide rail 15.When the detection probe 16 of the flatness detection mark device 7 on the side wall of the vertical telescopic rod 54 is tightly fitted with the side wall of the elevator guide rail 15, the control adjustment motor 63 stops working. When the detection probe 16 of the flatness detection mark device 7 is tightly fitted with the elevator guide rail 15, the detection head of the micrometer 9 is compressed and tightly fitted with the elevator guide rail 15. At this time, the adjustable rectangular frame 6 is adjusted. Then, the C-shaped sleeve 79 is removed, the controller 12 is connected to the computer terminal, and the electromagnet 28 and the detection motor 72 are started. When the electromagnet 28 is energized, the electromagnet 28 and the fixed magnet 27 repel each other with the same poles. The magnetic repulsion force pushes the active piston 20 to overcome the elastic force of the reset spring 26 and move toward the detection probe 16. The active piston 20 pushes the detection probe 1 through the connecting rod 21. 6 is tightly fitted with the side wall of the elevator guide rail 15, the detection motor 72 drives the lateral movement screw 68 to rotate, the lateral movement screw 68 drives the connecting piece 71 to move along the length direction of the workbench 1 through the detection slider 70, and the connecting piece 71 drives the adjustable rectangular frame 6 and the multiple flatness detection marking devices 7 installed on the side wall to move synchronously from one end of the elevator guide rail 15 to the other end of the elevator guide rail 15. During the movement, the micrometers 9 of the multiple flatness detection marking devices 7 respectively collect the flatness data of different side walls of the elevator guide rail 15 in real time and transmit the data to the wireless transmitting terminal 11 through the wireless transmitting terminal 11. The wireless transmitting terminal 11 uploads the collected data to the computer terminal for storage through the controller 12, which is convenient for analysis by software (existing Technology, no further description is given here), at the same time, the detection probe 16 is closely attached to the elevator guide rail 15. When the detection probe 16 moves to the concave part of the elevator guide rail 15 surface, the electromagnet 28 pushes the active piston 20 through the connecting rod 21 to drive the detection probe 16 to extend into the concave part and fit with the side wall of the concave part. The active piston 20 draws oil from the second oil cylinder 30 into the first oil cylinder 14 and drives the driven piston 31 to move close to the first oil cylinder 14. The driven piston 31 drives the pressure plate 23 to approach the reverse pressing bag 19 through the piston rod 32 and the offset bracket 22. The pressure plate 23 squeezes the reverse pressing bag 19. The oil in the reverse pressing bag 19 is sent into the telescopic sliding cavity 35 of the telescopic marking component 24 through the reverse pipe 46 and the transmission pipe 44 connected thereto. Thereby, the marking piston 36 of the telescopic marking assembly 24 is pushed to overcome the elastic force of the contraction spring 37 and move away from the first oil cylinder 14. The marking piston 36 pushes the sliding mounting cylinder 38 and the marking member 39 to extend out of the telescopic sliding cavity 35 through the pressing spring 42. At this time, the marking member 39 of the telescopic marking assembly 24 is attached to the side wall of the elevator guide rail 15 for marking. Different degrees of concave will cause different moving distances of the pressure plate 23. The deeper the concave, the greater the moving distance of the pressure plate 23, so the greater the pressure of the marking piston 36 on the marking member 39, and the thicker the line drawn by the marking member 39. When the detection probe 16 moves to the flat surface of the elevator guide rail 15, the side wall of the elevator guide rail 15 pushes the detection probe 16 to drive the active piston 20 to reset through the connecting rod 21.The active piston 20 drives the driven piston 31 to reset through the oil, and the driven piston 31 drives the pressure plate 23 to reset through the piston rod 32 and the offset bracket 22. The contraction spring 37 of the telescopic marking component 1 24 pulls the marking piston 36 to move close to the first oil cylinder 14 and reset, and the marking piston 36 presses the oil into the reverse pressing bag 19 again. At the same time, the marking piston 36 pulls the sliding mounting cylinder 38 and the marking member 39 to retract the telescopic sliding cavity 35 and reset through the pressing spring 42. During this process, the forward pressing bag 18 and the telescopic marking component 2 25 do not change. When the detection probe 16 moves to the protrusion on the surface of the elevator guide rail 15, the protrusion pushes the detection probe 16 through the connecting rod 21 to drive the active piston 20 to overcome the magnetic force of the electromagnet 28 and move close to the second oil cylinder. Cylinder 30, the active piston 20 presses the oil from the first cylinder 14 into the second cylinder 30 and drives the driven piston 31 to move away from the first cylinder 14, the driven piston 31 drives the pressure plate 23 to approach the positive pressing bag 18 through the piston rod 32 and the offset bracket 22, the pressure plate 23 squeezes the positive pressing bag 18, and the oil in the positive pressing bag 18 is sent into the telescopic sliding cavity 35 of the telescopic marking component 25 through the forward pipe 45 and the transmission pipe 44 connected thereto, thereby pushing the marking piston 36 of the telescopic marking component 25 to move away from the first cylinder 14, and the marking piston 36 pushes the sliding installation cylinder 38 and the marking member 39 to extend out of the telescopic sliding cavity 35 through the pressing spring 42. At this time, the marking member 39 of the telescopic marking component 25 is in contact with the elevator guide The side walls of the guide rail 15 are fitted together for marking. Different degrees of protrusion will cause different moving distances of the pressure plate 23. The more convex the side wall of the elevator guide rail 15 is, the greater the moving distance of the pressure plate 23 is, so that the greater the pressure of the marking piston 36 on the marking member 39, and the thicker the line drawn by the marking member 39 is. When the detection probe 16 moves to the flat surface of the elevator guide rail 15, the side wall of the elevator guide rail 15 pushes the detection probe 16 to drive the active piston 20 to reset through the connecting rod 21, and the active piston 20 drives the driven piston 31 to reset through the oil, and the driven piston 31 drives the pressure plate 23 to reset through the piston rod 32 and the offset bracket 22. The contraction spring 37 of the telescopic marking component 25 pulls the marking piston 36 to move close to the first oil cylinder 14 and reset, and the telescopic marking component 2 5, the marking piston 36 presses the oil into the forward pressing bag 18 again, and at the same time, the marking piston 36 of the telescopic marking assembly 25 pulls the sliding installation cylinder 38 and the marking member 39 to retract the telescopic sliding cavity 35 and reset through the pressing spring 42. During this process, the reverse pressing bag 19 and the telescopic marking assembly 1 24 remain unchanged, and the marking members 39 of different colors are convenient for distinguishing the inner concave and the outer convex. After the detection is completed, the control electromagnet 28 is powered off, and the reset spring 26 pushes the active piston 20 to make it located in the middle of the first oil cylinder 14, and at the same time controls the vertical telescopic rod 54 to extend and reset, and controls the adjustment motor 63 to reverse and reset, thereby driving the adjustable rectangular frame 6 to recover, and the adjustable rectangular frame 6 drives the multiple sets of flatness detection marking devices 7 away from the elevator guide rail 15.Then, the C-shaped ferrule 79 is respectively installed on the connecting rod 21 between the detection probe 16 and the first oil cylinder 14 of each flatness detection marking device 7, the detection probe 16 is limited, and then the clamping motor 77 is controlled to reverse and the lifting electric push rod 65 is controlled to retract and reset, and the elevator guide rail 15 is removed from the workbench 1.
