Description

Technical Field

[0001] The invention relates to the technical field of verticality detection, and in particular to a verticality detection device for a construction project. Background Art

[0002] Straightness is used to evaluate the vertical state between straight lines, between planes, or between a straight line and a plane, where one straight line or plane is the evaluation reference, and the straight line can be the straight part of the sample being tested or the straight motion trajectory, and the plane can be the plane part of the sample being tested or the plane formed by the motion trajectory; the rapid development of my country's construction industry has put forward higher technical requirements for construction project inspection. Verticality and flatness are important technical indicators to ensure construction quality and safety. It can help architects and engineers ensure the vertical accuracy of building-related structures, parts, and molds during the design and construction process, so verticality detection devices are used.

[0003] There are many technical defects in the existing verticality detection devices during measurement and use. First, the current detection object has an uneven clamping surface, which leads to poor clamping effect of the detection object, and it is easy to shake and deviate during detection, which affects the detection accuracy; second, the current detection device can only perform verticality detection on vertically placed detection objects. For some surfaces that are difficult to contact using vertical detection, the detection device cannot perform horizontal detection, resulting in a small detection range and low adaptability of the detection device; third, there is a large or small gap in the position of the moving track or sliding groove of the detector with telescopic function. During actual measurement, the cylinder seat drives the detection head to move up and down, which will generate vibration at the gap. The vibration phenomenon will interfere with the normal detection of the detection head, increase its jumping amplitude, and reduce the detection accuracy.

[0004] To sum up, considering that the existing facilities cannot meet the work needs, we propose a verticality detection device for construction projects. Summary of the invention

[0025] The present invention provides a construction engineering verticality detection device through improvement, which has the following significant improvements and advantages compared with the prior art: Start the screw motor, and after a series of transmissions, the long screw rotates, and the moving part moves to the right through the action of the screw nut sleeve, driving the dynamic clamp seat to slowly approach the other side of the detection object. When a group of second clamps on the dynamic clamp seat first contacts the detection object, the entire dynamic clamp seat will continue to move to the right, exerting pressure on the previous group of second clamps, causing the longitudinal slider to recover inward. After a series of transmissions, the first section of the other end of the transverse slider acts on the second section of another group of dynamic adjustment structures during the movement, causing the longitudinal slider of the other group of dynamic adjustment structures to extend outward, and use the second clamp to approach the surface of the detection object until the two groups of second clamps contact the surface of the detection object at the same time to achieve static balance, and cooperate with the two groups of first clamps to fix the detection object, adapt to the detection object with uneven clamping surface, and improve the clamping and fixing effect.

[0026] Start the servo motor, causing the two sets of rotating wheels to make circular motion. During the motion, the four sets of cam surfaces on the rotating wheels generate relative force with the arc head on the positioning column, causing the positioning column to move outward in a straight line. The positioning column partially extends out of the column hole and acts on the inner wall of the limit sleeve. The four sets of positioning columns contact the four inner walls of the limit sleeve at the same time, locking the telescopic bracket in a temporary position in the limit sleeve, thereby achieving the positioning effect, avoiding vibration of the telescopic bracket and the detector during follow-up, increasing shock resistance, and improving detection accuracy.

[0027] When the detector needs to be disassembled, the rotating bearing is twisted from the disassembly port to make the rotating bearing rotate in the circular slot of the holder. When it is blocked, it stops rotating. The detector and the telescopic bracket are directly taken out from the storage slot. At this time, several groups of blocks on the rotating bearing are separated from the corresponding guide ports at the same time to complete the disassembly, which is convenient for flexible installation and disassembly of the detector.

[0028] By starting the driving cylinder, the cylinder rod is retracted, causing the connecting fork to move straight to the right along the two sets of outer guide grooves. The driving shaft and the long waist groove generate relative force, causing the positioning shaft on the flip seat to rotate around the two sets of first bearing seats, driving the flip seat to flip 90° to the left. The detector switches from the vertical detection mode to the horizontal detection mode, thereby increasing the detection range of the detector and adapting to the detection objects with different structures. At this time, the lifting clamping seat drives the detection object to rise, and the vertical surface of the detection object can directly contact the detection head. At this time, there is no need to adjust the position of the telescopic bracket and the detector, reducing the complexity of operation.

[0029] The air pump is operated regularly, and several groups of air pipes are used to inflate the corresponding lubricators, so that the airbag telescopic column on each group of lubricators is inflated and expanded, causing the airbag telescopic column to expand and stretch in the external fixed tube, so that the lubricating sponge ball moves, and the four groups of sealing petals are opened, and partially enter the long waist groove. When the drive shaft contacts the lubricating sponge ball during movement, an extrusion force is generated on the lubricating sponge ball. The compression of the sponge causes the lubricating oil in the lubricating sponge ball to flow to the surface of the drive shaft and diffuse, so as to achieve the purpose of automatic lubrication, save time and effort, and solve the problem of drive shaft wear. On the other hand, the air release valve is opened to make the airbag telescopic column exhaust outward and shrink itself, so that the lubricating sponge ball can be returned to its position, and the four groups of sealing petals are re-sealed to achieve the effect of sealing and protecting the sponge ball to prevent it from being contaminated.

First cut surfaces 74 are provided at both ends of the transverse slider 71. The first cut surfaces 74 act on the two groups of dynamic adjustment structures 76 respectively. The two groups of dynamic adjustment structures 76 are respectively located inside the longitudinal groove 75, such as Fig.11 shown.

[0053] Specifically, the dynamic adjustment structure 76 includes a longitudinal slider 761, a second cut surface 762, a second slide groove 763, a spring pressure plate 764, a connecting spring 765 and a second clamp 766. Fig.11 and 12 shown.

[0054] In this embodiment, the longitudinal slider 761 is movably arranged in the longitudinal groove 75, and the longitudinal slider 761 moves linearly in the longitudinal groove 75. One end of the longitudinal slider 761 is provided with a second section 762 that interacts with the first section 74. The first section 74 and the second section 762 are both smooth surfaces and fit each other. A second slide groove 763 is opened through the middle of each group of longitudinal sliders 761.

[0055] In this embodiment, a spring pressure plate 764 extending into the second slide groove 763 is vertically fixed in the longitudinal groove 75, and two groups of connecting springs 765 are symmetrically connected between the spring pressure plate 764 and the groove wall of the second slide groove 763. The connecting springs 765 enhance the contact force and enable the two groups of longitudinal sliders 761 to automatically reset. A second clamp 766 is fixed to the other end of the longitudinal slider 761, and the second clamp 766 extends out of the longitudinal groove 75.

[0056] Further, the left end of the two groups of limit baffles 2 is provided with a first positioning bracket 88 acting on the flip seat 4, and the first positioning bracket 88 plays a supporting and positioning role. The right end of the two groups of limit baffles 2 is provided with a second positioning bracket 87 acting on the flip seat 4, and the second positioning bracket 87 plays a positioning role. Figure 3 shown.

[0057] Furthermore, the left end of the workpiece seat 5 is provided with a buffer bracket 86 acting on the top of the rodless cylinder 30, and the buffer bracket 86 plays a role of buffer support. Figure 1 shown.

[0058] Furthermore, the device can also be used to detect workpieces in factories.

[0059] When the present embodiment is in use, the object 19 to be detected is first placed on the upper end surface of the lifting clamping seat 7, so that one surface of the detected object 19 is in contact with the two groups of first clamps 61, and then the screw motor 69 is started to drive the small gear 68 to rotate, and the large gear 67 is rotated by meshing deceleration, and the long screw 65 rotates accordingly, and the moving part 63 is moved to the right along the linear groove 8 through the action of the screw nut sleeve 64 (the screw nut in the screw nut sleeve 64 moves along the spiral thread), driving the dynamic clamp seat 62 to slowly approach the other surface of the detected object 19, and when a group of second clamps 766 on the dynamic clamp seat 62 first contacts the detected object 19, since the other group of second clamps 766 has not yet contacted the detected object 19, the entire dynamic clamp seat 62 will continue to move to the right. , applying pressure to the first group of second chucks 766, so that the longitudinal slider 761 on the dynamic adjustment structure 76 moves inwardly, and a force is generated through the second section 762 and the first section 74 at one end of the transverse slider 71, causing the transverse slider 71 to move linearly in the transverse groove 70. During the movement of the transverse slider 71, the first section 74 at the other end acts on the second section 762 of the other group of dynamic adjustment structures 76, causing the longitudinal slider 761 of the other group of dynamic adjustment structures 76 to extend outward, and the second chucks 766 are used to approach the surface of the detection object 19 until the two groups of second chucks 766 are in contact with the surface of the detection object 19 at the same time to achieve static balance, and the detection object 19 is fixed with the two groups of first chucks 61.

[0060] Then the hydraulic lifting assembly is operated to drive the lifting clamping seat 7 to move up and down, so that the detection object 19 moves to the detection range of the detection instrument 36. At this time, the hydraulic cylinder 42 works, and the hydraulic rod 43 extends outward, driving the telescopic bracket 35 to slowly extend out of the storage slot 34, so that the detection head 37 on the detection instrument 36 is close to the detection object 19 until it touches the vertical surface of the detection object 19.

[0061] At this time, the servo motor 50 is started, and the rotating roller 52 is driven to rotate slowly through the coupling 51, causing the two sets of rotating wheels 54 to make circular motions. During the motion, the four sets of cam surfaces 55 on the rotating wheels 54 act on the four sets of positioners 58 respectively, and generate relative forces with the arc heads 582 on the positioning posts 581, causing the positioning posts 581 to move outward in a straight line along the convex track (the reset spring 585 is compressed to generate a reset elastic force), and the positioning posts 581 partially extend out of the post holes 46 to act on the limit On the inner wall of the sleeve 33, four groups of positioning columns 581 are in contact with the four inner walls of the limit sleeve 33 at the same time, locking the telescopic bracket 35 in a temporary position in the limit sleeve 33 to achieve the positioning effect, and then the rodless cylinder 30 is put into operation, and the cylinder slide 31 moves linearly on the rodless cylinder 30, driving the detector 36 to fall at a uniform speed, and utilizing the detection head 37 to maintain contact with the vertical surface of the detection object 19, and generate sensitive jumping action, and read the measurement result through the dial indicator 38, and transmit it to the data display instrument 89 in real time.

[0062] When the detector 36 needs to be disassembled, the positioning column 581 on the rotating wheel 54 is returned to its original position, and the rotating bearing 44 is screwed from the disassembly port 39 to make the rotating bearing 44 rotate in the circular slot of the holder 40. When it is blocked, it stops rotating, and the detector 36 and the telescopic bracket 35 are directly taken out from the storage slot 34. At this time, several groups of blocks 45 on the rotating bearing 44 are separated from the corresponding docking ports 41 at the same time to complete the disassembly.

[0063] When the detection object 19 needs to be placed horizontally for verticality detection, by starting the driving cylinder 23, the cylinder rod 22 is retracted, causing the connecting fork 20 to move linearly to the right along the two groups of outer guide grooves 17, driving the driving shaft 15 in the middle of the connecting fork 20 to move linearly, and generating a relative force with the long waist groove 14 (the driving shaft 15 and the long waist groove 14 generate relative movement), causing the positioning shaft 11 on the flip seat 4 to rotate around the two groups of first bearing seats 12, driving the flip seat 4 to flip 90° to the left, and the flip seat 4 is supported by the No. 1 positioning bracket 88, changing from a vertical state to a horizontal state. At the same time, the rodless cylinder 30 is supported by the buffer bracket 86, and the detector 36 switches from a vertical detection mode to a horizontal detection mode. At this time, it is only necessary to let the hydraulic lifting assembly work, and the lifting clamping seat 7 drives the detection object 19 to rise, and the vertical surface of the detection object 19 directly contacts the detection header 37. At this time, there is no need to adjust the position of the telescopic bracket 35 and the detector 36. Example

[0064] On the basis of the first embodiment, since the driving shaft 15 generates a large pressure when it moves in the long waist groove 14, it will cause the driving shaft 15 to wear after a long time, causing the connection position to loosen, reducing the detection accuracy. At present, there is a lack of a structure for automatic lubrication of the driving shaft 15. In order to solve the above technical problems, we have the following design, such as Figure 12-17 shown.

[0065] Specifically, an air pump 80 is installed at the middle position of the bottom of the driving part 13. The area where the air pump 80 is located inside the driving part 13 is provided with a porous joint 81. The porous joint 81 is connected to the lubricator 9 through a plurality of groups of air pipes 82. The air pipes 82 are located inside the driving part 13. Fig.13 and 15 shown.

[0066] Among them, the groove wall of the long waist groove 14 is provided with a mounting hole 85, and the lubricator 9 is installed in the mounting hole 85 and symmetrically distributed on the groove wall of the long waist groove 14, such as Fig.14 shown.

[0067] The bottom of the long waist groove 14 is provided with an oil receiving gap 83, which is connected to an oil drain hose 84 through a dark flow channel. The oil drain hose 84 extends downward out of the driving part 13. An oil receiving box is provided at the bottom of the rotating groove 3 for receiving waste oil discharged from the oil drain hose 84. Fig.13 and 14 shown.

[0068] The lubricator 9 specifically includes an outer fixing tube 91, a connecting rod 92, a fixing seat 93, an airbag telescopic column 94, a connecting hole 95, a connecting base plate 96, an oil sponge ball 97, a sealing flap 98 and a vent valve 99. Fig.16 and 17 shown.

[0069] In this embodiment, the external fixing tube 91 fits in the mounting hole 85 and can be taken out manually. The bottom of the external fixing tube 91 is connected to a fixing seat 93 through a plurality of connecting rods 92. An airbag telescopic column 94 is glued to the fixing seat 93 and has deformation restoration capability.

[0070] In this embodiment, the airbag telescopic column 94 extends upward into the interior of the external fixed tube 91, and a connecting hole 95 connected to the air pipe 82 is provided at the lower position of the outer side surface of the airbag telescopic column 94, and a deflation valve 99 connected to the interior of the airbag telescopic column 94 is installed at the bottom of the fixed seat 93.

[0071] In this embodiment, a connecting base plate 96 is fixedly provided at the upper end of the airbag telescopic column 94, and an oil sponge ball 97 is installed on the connecting base plate 96 (a certain amount of lubricating oil is sucked into the interior of the oil sponge ball 97), and four groups of sealing petals 98 are symmetrically installed on the wall of the outer fixed cylinder 91. The sealing petals 98 are fan-shaped thin sheets, and their softness is much stronger than that of the oil sponge ball 97. The sealing petals 98 have the ability to reset their deformation. The oil sponge ball 97 passes through the sealing petals 98 and extends out of the mounting hole 85, and interacts with the surface of the drive shaft 15.

[0072] When the present embodiment is in use, the air pump 80 is operated regularly, and the corresponding lubricators 9 are inflated by using a plurality of air pipes 82, so that the airbag telescopic columns 94 on each group of lubricators 9 are inflated and expanded, causing the airbag telescopic columns 94 to expand and stretch in the outer fixing tube 91, so that the lubricating sponge ball 97 moves, opens the four groups of sealing petals 98, extends out of the mounting hole 85, and partially enters the long waist groove 14. When the drive shaft 15 contacts the lubricating sponge ball 97 during the movement, an extrusion force is generated on the lubricating sponge ball 97, so that It is compressed and retreated into the long waist groove 14, and the lubricating oil in the oil sponge ball 97 flows to the surface of the drive shaft 15 through the compression of the sponge, and diffuses to achieve the purpose of automatic lubrication. The old oil on the surface of the drive shaft 15 will randomly drip to the bottom of the long waist groove 14, enter the oil receiving gap 83, and discharge the waste oil from the oil drain hose 84 through the dark flow channel. By opening the air release valve 99, the airbag telescopic column 94 is exhausted outward and contracts itself, so that the oil sponge ball 97 can be returned to its position, and the four sets of sealing petals 98 are sealed again.
