Description

Technical Field

[0002] In the process of modern engineering construction, leveling and installing wooden boards are often the preliminary steps to start construction. The existing mainstream leveling method for wooden board installation is still for operators to use a spirit level to perform the operation. The operation efficiency is relatively low, and the manual method is prone to errors and the levelness is not accurate enough. On this basis, the operator assists in using a laser level to correct the installation of the wooden board. Compared with using a spirit level, the operator can measure various positions of the wooden board through an entire horizontal surface, further adjusting the level effect. However, the laser level still requires the operator to manually calibrate the level before use. The operator also needs to move the laser level as he moves during the construction process. Every time the laser level moves, the levelness needs to be recalibrated. It is cumbersome to use, the degree of automation is not high, and the efficiency is relatively low.

[0031] Before the detection device is started, regardless of whether the main board 1 is horizontal or not, the frame 13 is used to release the freedom of the counterweight 14, so that the counterweight 14 can maintain a horizontal state under the action of gravity. The first motor 17 is energized to drive the inertia wheel 18 to rotate at a high speed. Part of the force generated by the inertia wheel 18 is in the same direction as the rotation axis, and the other part makes the turntable 15 rotate slowly around the reflective column 16 on the counterweight 14. During the subsequent movement of the detection device, the changes in the main board 1 will not affect the horizontal state of the counterweight 14, providing a basis for continuous horizontal measurement. The laser transmitter 20 on the main board 1 emits light, which is reflected by the reflector and then by the receiving plate 19, and then by the The reflective column 16 is rotated on the turntable 15, and the reflected light leaves a circular track on the receiving plate 19. The inclination angle of the light reflector is 45°, and the counterweight block 14 is in a horizontal state. The incident angle and reflection angle of the light emitted by the laser transmitter 20 are always the same. If the circular light track received by the receiving plate 19 is on the same horizontal plane, then the main board 1 is also in a horizontal state, and there is no need to use the balance adjustment mechanism for adjustment. If the main board 1 is not in a horizontal state, the circular light track received by the receiving plate 19 is not on the same horizontal plane. The receiving plate 19 determines which corner the lower side of the main board 1 is in through the track of the light, and controls the balance adjustment mechanism through the control system to adjust the main board 1 to a horizontal state.

[0032] Each of the balancing adjustment mechanisms comprises a fine-tuning motor 4, a screw 5, a slide 6, a leg 7 and a ball 8. The fine-tuning motor 4 is mounted above the main board 1. The screw 5 is connected to the motor shaft of the fine-tuning motor 4. The slide 6 is arranged below the main board 1. The screw 5 penetrates the main board 1 and extends into the slide 6. The leg 7 is slidably arranged on the slide 6. One side of the leg 7 extends into the slide 6. The leg 7 is threadedly connected to the screw 5. The ball 8 is rollingly mounted on the bottom of the leg 7. The inner part of the leg 7 is provided with a There are two driving units, which are vertically distributed in space. Each driving unit includes a small motor 9, a tooth comb shaft 10, a sleeve 11 and a plurality of rubber rings 12. The tooth comb shaft 10 is connected to the motor shaft of the small motor 9. The sleeve 11 is installed on the outside of the tooth comb shaft 10. The tooth comb shaft 10 is evenly distributed with a plurality of slits in a ring shape. The plurality of rubber rings 12 are sleeved on the sleeve 11, and the plurality of rubber rings 12 are respectively embedded in the plurality of slits. The rubber ring 12 is in contact with the sphere 8.

[0033] The fine-tuning motor 4 is energized to drive the screw rod 5 to rotate, and the screw rod 5 drives the support leg 7 to slide up and down in the slide cylinder 6 through spiral transmission, so as to adjust the height of the support leg 7 and realize the horizontal adjustment of the main board 1. The two sets of driving units drive the ball 8 to roll forward and sideways to control the movement of the entire detection device. The small motor 9 drives the tooth comb shaft 10 and the sleeve 11 to rotate, and the rubber ring 12 on the sleeve 11 drives the ball 8 to rotate through friction. When the ball 8 rolls forward, the rubber ring 12 on the other driving unit slides on the sleeve 11 and will not interfere with the forward rolling of the ball 8. When the ball 8 rolls sideways, the rubber ring 12 that drives the ball 8 to roll forward slides on the sleeve 11. The ball 8 is driven to roll by the two sets of driving units, and the entire device can be driven to move in two directions. The transmission is performed through the rubber ring 12 mounted on the sleeve 11, while avoiding interference with the rolling of the ball 8 in the other direction.

[0034] The angle-changing mechanism includes a second motor 21, a side bevel gear 22, an upper bevel gear 23 and a lower bevel gear 24. The second motor 21 is installed on the outside of the lower chassis 3, and the side bevel gear 22 is rotatably installed on the inside of the lower chassis 3. The motor shaft of the second motor 21 passes through the lower chassis 3 and is connected to the side bevel gear 22. The upper bevel gear 23 and the lower bevel gear 24 are symmetrically arranged up and down. The side bevel gear 22 is meshed with the upper bevel gear 23 and the lower bevel gear 24. An inner core shaft 26 is provided at the bottom of the upper bevel gear 23, and an outer sleeve shaft 25 is provided at the bottom of the lower bevel gear 24. The outer sleeve shaft 25 passes through the lower chassis 3, and the inner core shaft 26 passes through the lower bevel gear 24 and the outer sleeve shaft 25. A pair of upper cantilevers 27 are symmetrically installed on the inner core shaft 26, and a pair of lower cantilevers 28 are symmetrically installed on the inner core shaft 26. Four automatic suction cups 35 are respectively arranged at the ends of the pair of upper cantilevers 27 and the pair of lower cantilevers 28. The control system controls the second motor 21 to be energized to drive the side bevel gear 22 to rotate, and the side bevel gear 22 drives the upper bevel gear 23 and the lower bevel gear 24 to rotate. The upper bevel gear 23 and the lower bevel gear 24 have opposite directions. The upper bevel gear 23 drives the two automatic suction cups 35 to move through the inner core shaft 26 and the lower cantilever 28, and the lower bevel gear 24 drives the two automatic suction cups 35 to move through the outer sleeve shaft 25 and the upper cantilever 27 to adjust the positions of the four automatic suction cups 35 to adapt to the suction of wooden boards with different contour sizes.

[0035] Each of the automatic suction cups 35 includes an electric push rod 29, a sealed cylinder body 30 and a sliding suction cup 31. The electric push rod 29 is connected to the upper cantilever 27 or the lower cantilever 28. The sealed cylinder body 30 is arranged on the piston rod of the electric push rod 29. The sliding suction cup 31 is slidably installed in the sealed cylinder body 30. The sliding suction cup 31 passes through from top to bottom. A spring (not shown in the figure) is arranged between the sliding suction cup 31 and the sealed cylinder body 30. A free shifting block 32 is rotatably installed on the sliding suction cup 31. The bottom of the free shifting block 32 abuts against the sliding suction cup 31. A one-way gear is rotatably installed at the bottom position of the sealed cylinder body 30. The one-way gear puller 33 is provided with circular holes evenly distributed in a circular shape, and the interior of the sealed cylinder body 30 is provided with a valve inner hole 34, one end of the valve inner hole 34 is connected to the atmosphere, and the other end of the valve inner hole 34 is connected to the interior of the sealed cylinder body 30. The one-way gear puller 33 rotates in one direction, and the one-way gear puller 33 blocks the valve inner hole 34. The four electric push rods 29 push the sealed cylinder body 30 downward at the same time, and the sealed cylinder body 30 drives the sliding suction cup 31 to move downward until it contacts the wooden board. As the downward pressure continues, the spring is compressed, and the air in the sealed cylinder body 30 is squeezed out through the bottom of the sliding suction cup 31.

[0036] The free shift block 32 shifts the one-way gear dial 33 to rotate a certain angle, and the one-way gear dial 33 blocks the valve inner hole 34. When the electric push rod 29 moves upward, the spring opens the sealing cylinder 30 and the sliding suction cup 31, so that negative pressure is formed inside the sealing cylinder 30. The sliding suction cup 31 firmly sucks the wooden board and lifts it up. When the sliding suction cup 31 moves downward relative to the sealing cylinder 30, the free shift block 32 deflects upward and passes over the one-way gear dial 33, and will not drive the one-way gear dial 33 to rotate in the opposite direction. When the wooden board needs to be put down, the electric push rod 29 is moved again. At the same time, the sealing cylinder 30 is pushed downward, the wooden board touches the ground, and the operator installs the wooden board. With continued squeezing, the sliding suction cup 31 moves up, the spring is compressed again, and the free dial block 32 again drives the one-way gear dial 33 to rotate a certain angle. The circular hole on the one-way gear dial 33 is connected with the valve inner hole 34, and the inside of the sealing cylinder 30 is connected with the external atmosphere. The sliding suction cup 31 loses its adsorption force on the wooden board, and the wooden board is squeezed by the automatic suction cup 35, first squeezed once for adsorption, and then squeezed again for release, to achieve horizontal installation of the wooden board.

[0037] The working principle of the present invention is as follows: before the detection device is started, no matter whether the main board 1 is horizontal or not, the frame 13 is used to release the freedom of the counterweight 14, so that the counterweight 14 can maintain a horizontal state under the action of gravity. The first motor 17 is energized to drive the inertia wheel 18 to rotate at a high speed. A part of the force generated by the inertia wheel 18 is in the same direction as the rotation axis, and the other part makes the turntable 15 rotate slowly around the reflective column 16 on the counterweight 14. During the subsequent movement of the detection device, the change of the main board 1 will not affect the horizontal state of the counterweight 14, providing a basis for continuous horizontal measurement. The laser transmitter 20 on the main board 1 emits light, and the light is reflected to the receiving board 1 after hitting the reflector. 9, and because the turntable 15 makes the reflective column 16 rotate, the reflected light leaves a ring track on the receiving plate 19, the inclination angle of the light reflector is 45°, and the counterweight 14 is in a horizontal state, the incident angle and reflection angle of the light emitted by the laser transmitter 20 are always the same, if the annular light track received by the receiving plate 19 is on the same horizontal plane, then the main board 1 is also in a horizontal state, and there is no need to use the balance adjustment mechanism for adjustment. If the main board 1 is not in a horizontal state, the annular light track received by the receiving plate 19 is not on the same horizontal plane. The receiving plate 19 determines which corner the lower side of the main board 1 is in through the track of the light, and controls the balance adjustment mechanism through the control system to adjust the main board 1 to a horizontal state.

[0038] The fine-tuning motor 4 is energized to drive the screw rod 5 to rotate, and the screw rod 5 drives the support leg 7 to slide up and down in the slide cylinder 6 through spiral transmission, so as to adjust the height of the support leg 7 and realize the horizontal adjustment of the main board 1. The two sets of driving units drive the ball 8 to roll forward and sideways to control the movement of the entire detection device. The small motor 9 drives the tooth comb shaft 10 and the sleeve 11 to rotate, and the rubber ring 12 on the sleeve 11 drives the ball 8 to rotate through friction. When the ball 8 rolls forward, the rubber ring 12 on the other driving unit slides on the sleeve 11 and will not interfere with the forward rolling of the ball 8. When the ball 8 rolls sideways, the rubber ring 12 that drives the ball 8 to roll forward slides on the sleeve 11. The ball 8 is driven to roll by the two sets of driving units, and the entire device can be driven to move in two directions. The transmission is performed through the rubber ring 12 mounted on the sleeve 11, while avoiding interference with the rolling of the ball 8 in the other direction.

[0039] The control system controls the second motor 21 to be energized to drive the side bevel gear 22 to rotate, and the side bevel gear 22 drives the upper bevel gear 23 and the lower bevel gear 24 to rotate. The upper bevel gear 23 and the lower bevel gear 24 have opposite directions. The upper bevel gear 23 drives the two automatic suction cups 35 to move through the inner core shaft 26 and the lower cantilever 28, and the lower bevel gear 24 drives the two automatic suction cups 35 to move through the outer sleeve shaft 25 and the upper cantilever 27 to adjust the positions of the four automatic suction cups 35 to adapt to the suction of wooden boards with different contour sizes. The four electric push rods 29 simultaneously push the sealing cylinder 30 downward, and the sealing cylinder 30 drives the sliding suction cup 31 to move downward until it contacts the wooden board. As the downward pressure continues, the spring is compressed, and the air in the sealing cylinder 30 is squeezed out through the bottom of the sliding suction cup 31.

[0040] The free shift block 32 shifts the one-way gear dial 33 to rotate a certain angle, and the one-way gear dial 33 blocks the valve inner hole 34. When the electric push rod 29 moves upward, the spring opens the sealing cylinder 30 and the sliding suction cup 31, so that negative pressure is formed inside the sealing cylinder 30. The sliding suction cup 31 firmly sucks the wooden board and lifts it up. When the sliding suction cup 31 moves downward relative to the sealing cylinder 30, the free shift block 32 deflects upward and passes over the one-way gear dial 33, and will not drive the one-way gear dial 33 to rotate in the opposite direction. When the wooden board needs to be put down, the electric push rod 29 is moved again. At the same time, the sealing cylinder 30 is pushed downward, the wooden board touches the ground, and the operator installs the wooden board. With continued squeezing, the sliding suction cup 31 moves up, the spring is compressed again, and the free dial block 32 again drives the one-way gear dial 33 to rotate a certain angle. The circular hole on the one-way gear dial 33 is connected with the valve inner hole 34, and the inside of the sealing cylinder 30 is connected with the external atmosphere. The sliding suction cup 31 loses its adsorption force on the wooden board, and the wooden board is squeezed by the automatic suction cup 35, first squeezed once for adsorption, and then squeezed again for release, to achieve horizontal installation of the wooden board.
