DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0033] See also Figure 1-Figure 13 An engineering surveying level instrument support device provided by an embodiment of the present invention comprises a measuring platform 1, on which a mounting base plate 2 is provided, and further comprises: A connecting slide bar 9, one end of which is fixedly connected to the measuring platform 1, and a support frame 4 is fixedly mounted on the other end of the connecting slide bar 9, and a plurality of adjusting legs 6 are rotatably mounted on the support frame 4; and an adjustment control mechanism, wherein the adjustment control mechanism is respectively connected to the measuring platform 1, the support frame 4, the adjustment legs 6 and the connecting slide rod 9, wherein the adjustment control mechanism includes an adjustment drive component, an orientation detection component and an anti-tilt reinforcement component; The adjustment drive assembly is respectively connected to the measuring platform 1, the support frame 4, the adjustment leg 6 and the connecting slide rod 9, the orientation detection assembly is respectively connected to the support frame 4 and the adjustment leg 6, the anti-tilt reinforcement assembly is connected to the adjustment leg 6, and is electrically connected to the orientation detection assembly.

[0034] See also Figure 1-Figure 13, and also includes: a display control panel 5, which is fixedly connected to the support frame 4, and the display control panel 5 is also electrically connected to the adjustment drive component and the orientation detection component respectively.

[0035] When conducting engineering measurement, first, the level can be installed on the mounting base plate 2, and the entire device can be moved to the designated measurement position. In the process of moving the entire device, the four adjustment legs 6 are in a retracted state, and the anti-tilt reinforcement components on the bottom ends of the four adjustment legs 6 are in contact with each other. At this time, the anti-tilt reinforcement component plays an automatic positioning function, which can avoid the four adjustment legs 6 being in an active or dispersed state during the transportation or handling of the entire device, which is inconvenient for the storage of the device and the transportation or handling of the user. Then, after the entire device is moved to the measurement position, the automatic positioning function of the anti-tilt reinforcement component is manually released. At this time, Start the adjustment drive component, wherein the adjustment drive component can be driven by manpower or by mechanical drive, and the selection is made according to actual needs. After the adjustment drive component is started, it will drive the four adjustment legs 6 to gradually expand from the retracted state, wherein the expansion process of the four adjustment legs 6 includes three position states, namely, the position state where the bottom end of the adjustment leg 6 is on the inner side (the position state for storage or transportation, which is position one), the position state where the adjustment leg 6 is perpendicular to the support frame 4 (the rotation dividing point, which is position two), and the position state where the bottom end of the adjustment leg 6 is on the outer side (the position state for supporting the level and measuring, which is position three). When the legs 6 are unfolded and pass the second position, the anti-tilt reinforcement assembly is put into operation under the control of the orientation detection assembly, wherein the anti-tilt reinforcement assembly increases the contact area between the bottom end of the adjustment leg 6 and the ground, thereby enabling the level to be in a stable supported state in the entire state of the third position. After the measurement is completed, the adjustment drive assembly drives the four adjustment legs 6 to retract and pass the second position, and the anti-tilt reinforcement assembly is put into operation again under the control of the orientation detection assembly, thereby reducing the space occupied by the anti-tilt reinforcement assembly and positioning the structural state formed by the retraction, thereby saving the space occupied by the retracted state and facilitating the operation of the staff. In addition, By means of the display control panel 5, the electrical components on the adjustment control mechanism can be manually opened and closed, and the rotation angle of the adjustment leg 6 can be displayed, so that the staff can accurately control the rotation angle of the adjustment leg 6 according to the terrain conditions and measurement requirements, thereby improving the efficiency of the measurement work. The operation is simple, and it can avoid the support device from being affected by external factors and causing inaccurate measurements or tipping over. In addition, by controlling the structure of the adjustment leg 6 in two different states of the support device being expanded and contracted, it can provide convenience for the staff's transportation or handling work while ensuring the stability of the device during the measurement process, and it can also facilitate the storage of the device.

[0036] In one embodiment of the present invention, see Figure 1-Figure 13 , the regulating drive component comprises: An adjusting driving member 14, wherein the adjusting driving member 14 is fixedly mounted on the supporting frame 4, and a screw rod 15 is fixedly mounted on the output end of the adjusting driving member 14, and the other end of the screw rod 15 is rotatably connected to the measuring platform 1; An internal thread sleeve 16, wherein the internal thread sleeve 16 is sleeved on the screw rod 15 and is threadedly connected to the screw rod 15; And a push-pull driving unit, wherein the push-pull driving unit is respectively connected to the connecting slide rod 9 and the internal threaded sleeve 16, and is connected to the adjusting leg 6.

[0037] The push-pull driving unit comprises: A lifting frame body 3, wherein the lifting frame body 3 is fixedly connected to the internal threaded sleeve 16, and a sliding notch 8 is provided on the lifting frame body 3, wherein the connecting slide rod 9 is clamped in the sliding notch 8 and is slidably connected to the sliding notch 8; A driving connecting rod 11, one end of which is rotatably connected to the lifting frame body 3; And a driving adjustment seat 10 , wherein the driving adjustment seat 10 is fixedly mounted on the adjustment leg 6 , and the driving adjustment seat 10 is also rotatably connected to the other end of the driving connecting rod 11 .

[0038] The lifting frame body 3 is provided with four sliding notches 8, and the four connecting slide bars 9 are respectively clamped in the four sliding notches 8, and the two ends of the lifting frame body 3 are fixedly mounted with handle bars 12; There are four driving connecting rods 11, which are rotatably connected to the four corners of the lifting frame body 3 respectively. There are four driving adjustment seats 10, which are fixedly mounted on the four adjustment legs 6 respectively and rotatably connected to the four driving connecting rods 11 respectively.

[0039] After the whole device moves to the measuring position, the adjusting drive member 14 is started to drive the screw rod 15 to rotate, and the lifting frame body 3 can be moved upward through the coordinated transmission effect of the threads between the screw rod 15 and the internal threaded sleeve 16, and the sliding coordination effect between the sliding notch 8 and the connecting slide rod 9. In the process of the lifting frame body 3 moving upward, the driving connecting rod 11 can be driven to move upward synchronously, thereby driving the four adjusting legs 6 to rotate outward at the same time, so as to adjust the deployment state of the adjusting legs 6 according to the measured terrain adjustment and needs. When the adjusting legs 6 rotate, the orientation detection component can work, and the anti-tilt reinforcement component can be controlled to work, so that adaptive adjustment can be made according to the use state of the support device to ensure the smooth progress of the measurement work.

[0040] In one embodiment of the present invention, see Figure 1-Figure 13 , the orientation detection component comprises: A direction detector 13, wherein the direction detector 13 is fixedly connected to the support frame 4 via a support rod 21; A rotating shaft 23, wherein the rotating shaft 23 is fixedly connected to the adjusting leg 6 and is rotatably connected to the supporting frame 4, and one end of the rotating shaft 23 is also inserted into the direction detector 13 and is rotatably connected to the direction detector 13; and a rotation direction detection unit, wherein the rotation direction detection unit is located in the direction detector 13 and connected to the rotating shaft 23, and the rotation direction detection unit is also electrically connected to the anti-tilt reinforcement component.

[0041] The rotation direction detection unit comprises: A support seat 27, the support seat 27 is fixedly installed in the direction detector 13 and is rotatably connected to the rotating shaft 23, and the support seat 27 is also provided with a swinging portion 24; an elastic lever 26, one end of which passes through the swing portion 24 and is fixedly connected to the rotating shaft 23; A detection sensor 1 25 and a detection sensor 2 28, wherein the detection sensor 1 25 and the detection sensor 2 28 are both fixedly installed in the direction detector 13 and are respectively located on both sides of the support seat 27; and a limiting plate 22 , wherein the limiting plate 22 is fixedly installed in the direction detector 13 .

[0042] See also Figure 1-Figure 13 , the anti-tilt reinforcement assembly comprises: A support base 29, wherein the support base 29 is rotatably connected to the adjustment leg 6; A slide seat 33, wherein the slide seat 33 is slidably mounted in the support base 29, and an anti-tilt telescopic plate 30 is fixedly mounted on the slide seat 33, and one end of the anti-tilt telescopic plate 30 passes through the support base 29 and extends to the outside of the support base 29; A magnet block 34, the magnet block 34 is located in the support base 29 and is fixedly connected to the slide seat 33; and an electromagnetic controller 31 , wherein the electromagnetic controller 31 is fixedly connected to the support base 29 and electrically connected to the orientation detection component, and an adsorption portion 32 is also provided on the electromagnetic controller 31 .

[0043] Before the measurement is performed, that is, when the four adjustment legs 6 are in position one, the elastic lever 26 is located in the space directly opposite to the detection sensor 25. At this time, under the control of the detection sensor 25, the electromagnetic controller 31 is started and generates a magnetic attraction on the magnet block 34. The electromagnetic controller 31 can be in the form of an electromagnet, so that the anti-tilt telescopic plate 30 can be completely retracted into the telescopic chamber on the support base 29, and the two relatively arranged electromagnetic controllers 31 can be mutually adsorbed through the adsorption portion 32, so as to prevent the four adjustment legs 6 from becoming loose or loose during storage or transportation. In addition, At this time, the size of the overall support base 29 is small, which is convenient for the storage of the device and the handling of the staff. When performing measurement work, the electromagnetic controller 31 can be manually controlled to cut off the power, so that the adsorption part 32 loses the magnetic attraction, so that the four adjustment legs 6 are separated from each other for adjustment. Other methods can also be used. For example, under the pulling force of the driving connecting rod 11, the adjustment legs 6 will rotate, thereby overcoming the magnetic attraction at the adsorption part 32, so that the four adjustment legs 6 rotate at the same time, and drive the rotating shaft 23 to rotate. After rotating at a very small angle (a moment after the rotation), the elastic lever 26 rotates away from the position facing the detection sensor 25 (such as Fig. 9As shown), at this time, the electromagnetic controller 31 immediately and automatically enters the power-off state, thereby realizing the adjustment of the adjustment leg 6. No further details are given here. During the rotation of the adjustment leg 6, when the elastic lever 26 passes the position two and enters the position three state, the elastic lever 26 rotates to a position directly opposite to the detection sensor 28. At this time, the electromagnetic controller 31 is energized, and the direction of the current introduced is opposite. At this time, the electromagnetic controller 31 will produce a magnetic repulsion effect on the magnet block 34, and push the slide 33 to slide in the support base 29, thereby driving the anti-tilt telescopic plate 30 to move out of the outside of the support base 29, thereby increasing the contact area between the support base 29 and the ground, ensuring the stability of the device. Since the worse the terrain conditions, the more stable the support device needs to be, therefore, as the elastic lever 26 continues to rotate in the position directly opposite to the detection sensor 28 (that is, the larger the support surface of the adjustment leg 6, the more stable the overall support device), at the same time , the detection sensor 28 will also control the current passing into the electromagnetic controller 31 to gradually increase (at this time, the magnetic repulsion between the electromagnetic controller 31 and the magnet block 34 gradually increases, and the thrust on the slide 33 increases accordingly) to ensure the stability of the anti-tilt telescopic plate 30 after extending out of the support base 29 during the entire measurement process, thereby further ensuring the stability of the level support. Among them, the number of direction detectors 13 is two, and the two direction detectors 13 respectively control the magnetic force directions of the anti-tilt reinforcement components on the two groups of relatively arranged adjustment legs 6, so that when the adjustment legs 6 are in different position states, the magnetic force direction and magnetic force size of the electromagnetic controller 31 can control the anti-tilt telescopic plate 30 to shrink or extend on the support base 29, and can make the adsorption part 32 always in a state of mutual adsorption, thereby ensuring the stability of the support device during the measurement process, and providing convenience for measurement, transportation or storage operations, etc., which will not be elaborated here.

[0044] In one embodiment of the present invention, see Figure 1-Figure 13 , further comprising: a placement groove 35, the placement groove 35 is opened on the anti-tilt telescopic plate 30, and a positioning socket 38 is opened in the middle of the placement groove 35; A reinforcing cone rod 37, wherein the reinforcing cone rod 37 is inserted into the positioning socket 38 and is connected to the positioning socket 38 in a damping sliding manner; And a lifting baffle 36 , wherein the lifting baffle 36 is fixedly mounted on the top end of the reinforcing cone rod 37 , wherein the sum of the heights of the lifting baffle 36 and the reinforcing cone rod 37 is equal to the height of the slide seat 33 .

[0045] It also includes: an adjustable top rod 17, the adjustable top rod 17 is fixedly mounted on the lifting frame body 3; A square telescopic rod 18, one end of which passes through the measuring platform 1 and is inserted into the connecting slide bar 9, and the square telescopic rod 18 is also slidably connected to the connecting slide bar 9, and the other end of the square telescopic rod 18 is fixedly connected to the mounting base plate 2; A telescopic round rod 20, wherein the telescopic round rod 20 is inserted into the mounting seat plate 2 and is slidably connected to the mounting seat plate 2; And a telescopic top plate 7, the telescopic top plate 7 is fixedly connected to the other end of the telescopic round rod 20, and is detachably connected to the adjustable top rod 17, and a push-pull groove 19 is also opened on the telescopic top plate 7.

[0046] During the measurement process, when the terrain conditions are too complex or the external influence is large, at this time, in order to ensure the stability of the support device, after the anti-tilt telescopic plate 30 extends out of the support base 29, the reinforcing cone rod 37 is inserted into the positioning socket 38, and the lifting baffle 36 is pushed to make the bottom end of the reinforcing cone rod 37 inserted into the soil, so that the support device can be limited to avoid translation or shaking on the ground. Among them, since the total height of the lifting baffle 36 and the reinforcing cone rod 37 is equal to the height of the sliding seat 33, after the measurement is completed, the lifting baffle 36 can be pulled manually to make the lifting baffle 36 and the reinforcing cone rod 37 in the positioning socket. The lifting baffle 36 and the reinforcing cone rod 37 are moved up a short distance in the hole 38, so that when the anti-tilt telescopic plate 30 is retracted into the support base 29, the lifting baffle 36 and the reinforcing cone rod 37 follow the anti-tilt telescopic plate 30 and enter the support base 29 for storage. Of course, the reinforcing cone rod 37 can also be directly taken out of the positioning hole 38 and directly placed in other storage boxes provided on the support device. No further details will be given here. In addition, when the support surface of the four adjustment legs 6 is increased, although the stability of the device during the measurement process can be guaranteed, the overall measured height will also decrease (that is, the height of the level from the ground will decrease). This situation may not meet certain measurement requirements. This affects the practicability and flexibility of the equipment and makes the use of the equipment have certain limitations. At this time, in order to save production costs, the overall device can be lowered and the height of the level instrument from the ground needs to be increased. Before measuring, the telescopic top plate 7 can be pulled by manpower to make the telescopic round rod 20 extend out of the outside of the mounting base plate 2 and move the telescopic top plate 7 to the top of the adjustable top rod 17 (wherein, at the initial stage of measurement, the adjustable top rod 17 is in a lower position connected to the slide bar 9 together with the lifting frame 3. At this time, the top end of the adjustable top rod 17 is located below the mounting base plate 2). As the lifting frame 3 drives the adjustable top rod 17 Move upward. At this time, the support surface of the adjustment leg 6 gradually increases. When the adjustable top rod 17 contacts the telescopic top plate 7, it will push the telescopic top plate 7 and the mounting seat plate 2 to move upward synchronously. At this time, the square telescopic rod 18 will slide on the measuring platform 1 and gradually extend out of the outside of the connecting slide rod 9, thereby increasing the distance between the measuring platform 1 and the mounting seat plate 2 to achieve the purpose of increasing the height of the level from the ground. In addition, the adjustable top rod 17 can be in the form of a threaded lifting rod. When the height of the level is not suitable, the height of the level from the ground can be changed by fine-tuning the height of the adjustable top rod 17 by manpower.
