Description

Technical Field

[0001] The invention relates to the technical field of construction engineering, in particular to a building deformation monitoring device for construction engineering. Background Art

[0002] Construction engineering refers to the activities of new construction, reconstruction, expansion or demolition of land and its ancillary buildings. These activities involve excavation, filling, leveling of land, and design and construction of the structure, appearance and interior space of the building. The purpose of construction engineering is to create buildings and structures suitable for human habitation, work, leisure or specific purposes. After the construction is put into use, it is still necessary to monitor regularly. Building deformation monitoring refers to the process of systematically observing, recording and analyzing the changes in the shape and position of the building under the influence of external loads (such as wind loads, earthquake loads, temperature changes, etc.) and internal loads (such as structural deadweight, use loads, etc.), as well as environmental factors (such as compression of foundation soil, changes in groundwater levels, etc.). The purpose of this process is to evaluate the safety, stability and durability of the building, and to provide a scientific basis for the maintenance, reinforcement or design of the building.

[0003] After searching, it is found that there are problems in the process of deformation monitoring of buildings by surveying instruments in the prior art. When monitoring buildings, the staff place the bracket and the surveying instrument on the ground in the building area, and the ground may be uneven, which will cause the bracket and the surveying instrument to tilt, affecting the accuracy of the monitoring results; in addition, during monitoring, the staff may change the direction of the surveying instrument and adjust the angle of the telescope group. This change changes the position of the overall center of gravity of the surveying instrument, so that the center of gravity of the surveying instrument is not on the same central axis as the center of gravity of the bracket, causing the bracket to tilt due to uneven force. The tilt of the bracket also causes the surveying instrument to tilt, further causing deviations in the measurement results of the surveying instrument, affecting the deformation monitoring of the building. Therefore, based on the above search and combined with the prior art, a building deformation monitoring device for construction engineering is proposed to solve the above problems.

[0030] 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.

[0031] In a typical implementation of this application, please refer to Figures 1 to 11 A building deformation monitoring device for construction engineering includes a support box 1, a connection box 2 is arranged on the top surface of the support box 1, a base plate 4 is arranged on the top surface of the connection box 2, a rubber bushing 3 is fixedly installed between the connection box 2 and the base plate 4, and is used to seal the gap between the rubber bushing 3 and the base plate 4, the rubber bushing 3 is a rubber tubular structure and has a certain margin, so that it has a telescopic characteristic, which is convenient for workers to adjust the angle of the base plate 4, a surveying and mapping body 5 is arranged on the top surface of the base plate 4, a telescope group 6 is rotatably connected to the inside of the surveying and mapping body 5, and the telescope group 6 inside the surveying and mapping body 5 can be rotated to adjust the angle of the telescope group 6 for observing the building, a monitoring mechanism 7 is arranged on the inner bottom surface of the connection box 2, and is used to monitor the deformation of the building, and a supporting mechanism 8 is arranged on the outer circular wall surface of the support box 1, and is used to support the support box 1;

[0032] The monitoring mechanism 7 includes a gyroscope 40, which is fixedly mounted on the bottom surface of the substrate 4 and is used to measure the tilt angle of the substrate 4. An information processing unit for use with the gyroscope 40 is fixedly mounted on the inner bottom surface of the connection box 2. This is a prior art and will not be described in detail. The information processing unit is electrically connected to the gyroscope 40 and can process information transmitted by the gyroscope 40. A support table 34 is fixedly mounted on the inner bottom surface of the connection box 2. A support rod 39 is fixedly mounted on the top surface of the support table 34. The support rod 39 is universally connected to the bottom surface of the substrate 4 through a universal joint 38. The universal joint 38 is mounted on the bottom surface of the substrate 4. The top end of the support rod 39 is connected to the universal joint 38. The freedom of rotation of the substrate 4 is improved through the universal joint 38.

[0033] A plurality of connection frames 35 are fixedly mounted on the inner bottom surface of the connection box 2, and an electric push rod 36 is rotatably connected to the inner part of the connection frame 35 via a rotating shaft. A plurality of mounting frames 37 are fixedly mounted on the bottom surface of the base plate 4, and the telescopic shaft of the electric push rod 36 is rotatably connected to the mounting frame 37 via a rotating shaft.

[0034] Specifically, firstly, relevant data of the building are collected, such as design drawings, geological survey reports, and surface building plans; secondly, a deformation monitoring plan is determined, and the monitoring purpose, i.e., the tilt of the building, is determined based on the collected data, and the degree of displacement of the building or its structural parts relative to the vertical axis is monitored; thirdly, parameters commonly used in building structure deformation monitoring are selected and the surveying and mapping machine 5 and the telescope group 6 are used for monitoring, and finally, data are collected, processed, and analyzed to obtain the deformation of the building;

[0035] In the process of building construction, the staff will use the surveying machine 5 and the telescope group 6 to monitor the deformation of the building. At this time, the base plate 4 may tilt due to the uneven ground. When the gyroscope 40 detects that the base plate 4 is not in a horizontal state, the detected tilt angle will be transmitted to the information processing unit. The information processing unit processes the information and feeds back to the multiple electric push rods 36. The telescopic axes of the multiple electric push rods 36 move outward or retract inward to adjust the angles of the base plate 4, the surveying machine 5 and the telescope group 6, so that the surveying machine 5 and the telescope group 6 remain horizontal, thereby reducing the error of the building deformation monitoring result.

[0036] The monitoring mechanism 7 also includes a support box 41, which is slidably connected to the top surface of the base plate 4, and a screw rod 54 is rotatably connected inside the support box 41. Both ends of the screw rod 54 are rotatably connected to the inner sides of the support box 41 through bearings. A movable block 53 is threadedly connected to the outer circumferential wall of the screw rod 54. A limiting rod 55 is fixedly installed inside the support box 41, and the limiting rod 55 is slidably connected to the movable block 53. The limiting rod 55 can limit the movement of the movable block 53. The top surface of the movable block 53 is fixedly connected to the bottom surface of the surveying and mapping machine body 5;

[0037] The outer circumferential wall surface of the screw rod 54 is fixedly sleeved with a bevel gear 1 56, and the outer circumferential wall surface of the bevel gear 1 56 is meshedly connected with a bevel gear 2 58. One side of the support box 41 is rotatably connected with a support column 57 through a bearing, one end of the support column 57 is fixedly connected to one end of the bevel gear 2 58, and the other end of the support column 57 is fixedly installed with a knob 4 60. The top surface of the base plate 4 is fixedly installed with a pressure test pad 61 for measuring the center of gravity position of the surveying and mapping body 5 and the telescope group 6, and the pressure test pad 61 is electrically connected to the information processing unit;

[0038] The principle of the pressure test pad 61 to measure the center of gravity of an object is mainly based on the principle of moment balance. This method uses force sensors at multiple support points to sense the force applied by the object, and collects the force data signals sensed by the sensors through a data acquisition system. Then, these signals are resolved to obtain the position of the center of gravity of the object.

[0039] The staff sets the center of the pressure test pad 61 as the reference point, and this position is on the central axis of the support box 1. When the staff conducts building deformation monitoring, they will first adjust the orientation of the surveying and mapping body 5 and the telescope group 6, and then adjust the angle of the telescope group 6. The change in the orientation of the surveying and mapping body 5 and the adjustment of the angle of the telescope group 6 change the overall center of gravity of the surveying and mapping body 5 and the telescope group 6, so that their center of gravity and the center of gravity of the support box 1 are not on the central axis. At this time, the overall center of gravity of the surveying and mapping body 5 and the telescope group 6 is offset from the reference point. The staff turns the knob 4 60 to drive the support column 57 and the bevel gear 2 58 to rotate, the bevel gear 2 58 rotates to drive the bevel gear 1 56 to rotate, the bevel gear 1 56 rotates to drive the screw 54 to rotate, the screw 54 rotates to drive the movable block 53 to move, and the movable block 53 moves to drive the surveying and mapping body 5 and the telescope group 6 to move, thereby adjusting the center of gravity of the surveying and mapping body 5 and the telescope group 6 in the horizontal direction;

[0040] A support frame 65 is fixedly installed on the top surface of the base plate 4, and a connecting rod 49 is rotatably connected inside the support frame 65. The top surface of the connecting rod 49 is connected to a spur gear 48 through a rotating shaft. A mounting groove 50 is provided on one side of the connecting rod 49, and a connecting rod 51 is rotatably connected inside the mounting groove 50 through a rotating shaft. Two mounting blocks 52 are fixedly installed on one side of the support box 41, and one end of the connecting rod 51 is rotatably connected to the two mounting blocks 52 through a rotating shaft. A toothed plate 47 is slidably connected to the top surface of the base plate 4, and the toothed plate 47 is meshed with the spur gear 48. The top surface of the base plate 4 A worm gear 2 44 is rotatably connected, and a spur gear 1 45 is coaxially connected to the worm gear 2 44. The spur gear 1 45 meshes with a toothed plate 47. A fixed roller 46 is rotatably connected to the top surface of the base plate 4 through a bearing. The inner circumferential wall surface of the worm gear 2 44 and the inner circumferential wall surface of the spur gear 1 45 are both fixedly sleeved with the outer circumferential wall surface of the fixed roller 46. Two bearing seats 2 42 are fixedly installed on the top surface of the base plate 4. A double-lead worm 43 is rotatably connected between the two bearing seats 2 42. The worm gear 2 44 meshes with the double-lead worm 43. A knob 3 59 is fixedly installed on one end of the double-lead worm 43.

[0041] When the center of the surveying and mapping machine body 5 and the telescope group 6 are longitudinally offset from the reference point on the pressure test pad 61, the staff member turns the knob three 59 to drive the double-lead worm 43 to rotate, the double-lead worm 43 rotates to drive the worm gear two 44 and the spur gear one 45 to rotate, the spur gear one 45 rotates to drive the gear plate 47 to move, the gear plate 47 moves to drive the spur gear two 48 to rotate, the spur gear two 48 rotates to drive the connecting rod one 49 to rotate, the connecting rod one 49 rotates to drive the connecting rod two 51 to move, so that the surveying and mapping machine body 5 and the telescope group 6 move in the longitudinal direction, and then the center of gravity of the surveying and mapping machine body 5 and the telescope group 6 is moved longitudinally;

[0042] With the above technical features, by setting up the surveying and mapping machine body 5 and the telescope group 6, in the construction project, the workers will use the surveying and mapping machine body 5 and the telescope group 6 to monitor the deformation of the building, specifically to monitor the degree of deviation of the building or its structural part relative to the vertical axis, collect data and analyze it to obtain the deformation of the building. In this process, the bracket under the support box 1 can support the support box 1. During the use of the surveying and mapping machine body 5 and the telescope group 6, due to the uneven ground, the surveying and mapping machine body 5 and the telescope group 6 may tilt. When the surveying and mapping machine body 5 and the telescope group 6 are uneven due to the uneven ground, When tilting, the gyroscope 40 measures the tilt angle and transmits the information to the information processing unit, which processes the information and feeds back to the multiple electric push rods 36. The telescopic axes of the multiple electric push rods 36 move outward or contract to make the base plate 4 rotate around the support rod 39 through the universal joint 38, and at the same time make the rubber bushing 3 deform, so as to adjust the angle of the base plate 4, and then adjust the angle of the surveying and mapping machine body 5 and the telescope group 6, keep the surveying and mapping machine body 5 and the telescope group 6 level, avoid the surveying and mapping machine body 5 and the telescope group 6 from tilting due to uneven ground, and improve the accuracy of monitoring building deformation;

[0043] At the same time, in the subsequent use of the surveying and mapping body 5 and the telescope group 6, the staff may rotate the surveying and mapping body 5 and the telescope group 6 to change their orientation and adjust the angle. The change in orientation and angle of the surveying and mapping body 5 and the telescope group 6 causes the position of the center of gravity of the surveying and mapping body 5 and the telescope group 6 to change. After the position of the center of gravity of the surveying and mapping body 5 and the telescope group 6 is changed, it is not on the same central axis as the center of gravity of the support box 1. The staff sets a reference point on the pressure test pad 61. When the center of gravity of the surveying and mapping body 5 and the telescope group 6 is not on the reference point, the information processing unit will start the alarm light 33, and the alarm light 33 emits light to warn the staff;

[0044] Then the staff member turns the knob 4 60, and the rotation of the knob 4 60 drives the support column 57 to rotate, and the rotation of the support column 57 drives the bevel gear 2 58 to rotate, and the rotation of the bevel gear 2 58 drives the bevel gear 1 56 to rotate, and the rotation of the bevel gear 1 56 drives the screw rod 54 to rotate, and the rotation of the screw rod 54 causes the movable block 53 to move along the screw rod 54, and the movement of the movable block 53 also moves along the limiting rod 55, and the limiting rod 55 can limit the movement of the movable block 53, and the movement of the movable block 53 drives the surveying and mapping machine body 5 and the telescope group 6 to move, and the movement of the surveying and mapping machine body 5 and the telescope group 6 causes their center of gravity to move, thereby laterally moving the center of gravity of the surveying and mapping machine body 5 and the telescope group 6;

[0045] At the same time, the staff member rotates knob three 59, and the rotation of knob three 59 drives the double-lead worm 43 to rotate, and the rotation of the double-lead worm 43 drives the worm gear two 44 to rotate, and the rotation of the worm gear two 44 drives the spur gear one 45 to rotate through the fixed roller 46, and the rotation of the spur gear one 45 drives the toothed plate 47 to move leftward, and the toothed plate 47 moves leftward and drives the spur gear two 48 to rotate clockwise, and the clockwise rotation of the spur gear two 48 drives the connecting rod one 49 inside the support frame 65 to rotate outward, and the outward rotation of the connecting rod one 49 drives the connecting rod two 51 to rotate outward, and the outward rotation of the connecting rod two 51 drives the support box 41 to move forward in the longitudinal direction, and the forward movement of the support box 41 drives the surveying and mapping machine body 5 and the telescope group 6 to move forward, thereby changing the center of gravity of the surveying and mapping machine body 5 and the telescope group 6 in the longitudinal direction;

[0046] The tooth thickness of the double-lead worm 43 varies along the axial direction. This design allows the clearance of the worm gear to be adjusted to the optimal state. When the clearance of the worm gear becomes larger during use, the clearance of the worm gear can be reduced by adjusting the axial position of the worm, so that it can be used to achieve bidirectional rotation with high precision.

[0047] On the contrary, the staff rotates knob three 59 in the reverse direction, and the reverse rotation of knob three 59 drives the double-lead worm 43 and the worm gear two 44 to rotate in the reverse direction, and the reverse rotation of the worm gear two 44 drives the spur gear one 45 to rotate in the reverse direction.

[0048] The spur gear 1 45 rotates in the opposite direction to make the tooth plate 47 rotate counterclockwise, and the tooth plate 47 rotates counterclockwise to make the connecting rod 1 49 drive the connecting rod 2 51 to move inward, and the connecting rod 2 51 moves inward to drive the support box 41 to move backward in the longitudinal direction, and the support box 41 moves backward to drive the surveying and mapping machine body 5 and the telescope group 6 to move backward, and the surveying and mapping machine body 5 and the telescope group 6 move backward so that their center of gravity moves backward;

[0049] After the alarm light 33 emits light, the staff adjusts the center of gravity of the surveying and mapping machine body 5 and the telescope group 6 in the horizontal and vertical directions through the above process so that the center of gravity of the surveying and mapping machine body 5 and the telescope group 6 is on the reference point on the pressure test pad 61 and the center of gravity of the surveying and mapping machine body 5 and the telescope group 6 is on the same central axis as the center of gravity of the support box 1. At this time, the alarm light 33 is turned off to prevent the change of the center of gravity of the surveying and mapping machine body 5 and the telescope group 6 from affecting the bracket and preventing the surveying and mapping machine body 5 and the telescope group 6 from shifting due to the shift of the bottom bracket of the support box 1, thereby further improving the accuracy of the surveying and mapping machine body 5 and the telescope group 6 in monitoring building deformation;

[0050] In this process, the staff measures the inclination of the surveying and mapping machine body 5 and the telescope group 6 caused by the uneven ground through the gyroscope 40, and then cooperates with the multiple electric push rods 36 to adjust the position of the base plate 4, so that the surveying and mapping machine body 5 and the telescope group 6 always remain horizontal, and prevent the surveying and mapping machine body 5 and the telescope group 6 on the base plate 4 from tilting due to the uneven ground, and avoid the uneven ground from affecting the result of building deformation monitoring; secondly, the staff moves the surveying and mapping machine body 5 and the telescope group 6 horizontally and vertically so that their center of gravity is on the same central axis as the center of gravity of the support box 1, and prevents the center of gravity offset of the surveying and mapping machine body 5 and the telescope group 6 from affecting the measurement result, further improving the accuracy of building deformation monitoring, achieving the deformation monitoring effect of the building, and facilitating the staff to use the surveying and mapping machine body 5 and the telescope group 6 to monitor the deformation of the building in the construction project;

[0051] The top surface of the base plate 4 is provided with a support groove 62 for supporting the movement of the support box 41. Two limit blocks 63 are fixedly installed on the bottom surface of the support box 41. A limit rod 64 for limiting the limit block 63 is fixedly installed inside the support groove 62. The limit block 63 is slidably connected with the limit rod 64. The movement of the surveying and mapping machine body 5 and the telescope group 6 drives the support box 41 to move. The movement of the support box 41 drives the limit block 63 to move inside the support groove 62 along the limit rod 64.

[0052] Specifically, through the setting of the surveying and mapping body 5, the movement of the surveying and mapping body 5 and the telescope group 6 drives the support box 41 to move, and the movement of the support box 41 drives the limit block 63 to move inside the support groove 62 along the limit rod 64. The limit block 63 and the limit rod 64 can limit the movement of the surveying and mapping body 5 and the telescope group 6 to prevent the surveying and mapping body 5 and the telescope group 6 from shifting during movement.

[0053] As a preferred implementation in this embodiment, please refer to Figure 1 to Figure 6 The support mechanism 8 includes a plurality of fixed blocks 10, which are fixedly mounted on the outer circumferential wall surface of the support box 1. A connecting block 11 is rotatably mounted between every two fixed blocks 10 via a rotating shaft. Two supporting rods 12 are fixedly mounted on the bottom surface of the connecting block 11. A fixing box 15 is fixedly mounted on one end of the two supporting rods 12. A plug-in board 16 is slidably connected to the inside of the fixing box 15. A screw 20 for locking the length of the plug-in board 16 is mounted on one side of the fixing box 15. A plurality of circular through holes are opened on one side of the fixing box 15. A threaded groove begins to be formed on one side of the plug-in board 16. One end of the screw 20 passes through the circular through hole and is threadedly connected to the inner circumferential wall surface of the threaded groove.

[0054] The staff adjusts the height of the surveying and mapping machine body 5 and the telescope group 6 by adjusting the position of the plug-in board 16 in the fixing box 15;

[0055] The staff rotates the support rod 2 12 outward to drive the fixing box 15 and the plug board 16 to rotate outward to a suitable position and put one end of the plug board 16 into the soil. At this time, the fixing box 15, the plug board 16, the connecting block 1 11 and the support rod 2 12 can support the support box 1 to improve the stability of the support box 1;

[0056] The outer circular wall surface of the two support rods 12 is slidably connected with a sliding block 19, and a support rod 19 is fixedly installed on the bottom surface of the support box 1, and a support ring 13 is slidably connected to the outer circular wall surface of the support rod 19. A support rod 3 22 is rotatably connected to one side of the sliding block 19, and one end of the support rod 3 22 is rotatably connected to the outer circular wall surface of the support ring 13. Two connecting blocks 21 are fixedly installed on one side of the sliding block 19, and one end of the support rod 3 22 is rotatably connected to the connecting block 21 through a rotating shaft. A plurality of positioning blocks 23 are fixedly installed on the outer circular wall surface of the support ring 13, and the other end of the support rod 3 22 is rotatably connected to the two positioning blocks 23 through a rotating shaft. A screw 14 for locking the position of the support ring 13 is installed on the outer circular wall surface of the support ring 13, and a plurality of threaded grooves are provided on the outer circular wall surface of the support rod 19, and a circular through hole is provided on one side of the plug-in plate 16, and one end of the screw 14 passes through the circular through hole and is threadedly connected to the inner circular wall surface of the threaded groove;

[0057] When the staff member rotates the support rod 2 12 outward, the sliding block 19 slides along the two support rods 2 12, and the sliding of the sliding block 19 drives the support rod 3 22 to rotate, and the rotation of the support rod 3 22 drives the support ring 13 to slide on the support rod 1 9, and the support ring 13 and the support rod 3 22 can limit the rotation of the support rod 2 12. When the support rod 2 12 is rotated to a suitable angle, the staff member uses the screw 14 to lock the position of the support ring 13 on the support rod 1 9. At this time, the support ring 13 and the support rod 3 22 can support the support rod 2 12, reduce the shaking of the support rod 2 12, the fixing box 15 and the plug-in board 16, and thus prevent the surveying and mapping machine body 5 and the telescope group 6 from shaking;

[0058] Specifically, through the provided plug-in board 16, the staff moves the plug-in board 16 outward to a suitable position, and then the staff puts the second screw 20 into the circular through hole on the fixing box 15 and rotates the second screw 20 so that one end of the second screw 20 enters the thread groove on the plug-in board 16, thereby determining the height of the surveying and mapping machine body 5 and the telescope group 6;

[0059] Then the staff rotates the support rod 2 12 outward to drive the connecting block 11 to rotate between the two fixed blocks 10. The support rod 2 12 also rotates the fixed box 15 and the plug board 16 outward until the plug board 16 is rotated to a suitable angle. The staff inserts the plug board 16 into the soil. The fixed box 15, the plug board 16 and the support rod 2 12 cooperate to support the support box 1.

[0060] At the same time, in the process of the support rod 2 12 driving the fixing box 15 and the plug board 16 to rotate outward, the sliding block 19 slides downward along the two support rods 2 12, and the sliding block 19 moves downward through the connecting block 21 to drive the support rod 3 22 to rotate downward, and the support rod 3 22 rotates downward to drive the support ring 13 to slide along the support rod 1 9. After the fixing box 15 and the plug board 16 are rotated to a suitable angle, the staff places the screw 14 on the support ring 13 and rotates the screw 14 so that the screw 14 enters the inside of the threaded groove on the support rod 1 9, thereby locking the position of the support ring 13 and the support rod 3 22. The support ring 13 and the support rod 3 22 can support the support rod 2 12 to prevent the support rod 2 12 from shaking, thereby reducing the shaking of the fixing box 15 and the plug board 16;

[0061] The top surface of the base plate 4 is fixedly mounted with a slide rail 66 for supporting the tooth plate 47 to slide, and the bottom surface of the tooth plate 47 is fixedly mounted with a slider 67, which is slidably connected to the slide rail 66. The movement of the tooth plate 47 drives the slider 67 to slide on the slide rail 66. The slide rail 66 and the slider 67 cooperate to limit the movement of the tooth plate 47.

[0062] Specifically, the tooth plate 47 is provided, and the movement of the tooth plate 47 drives the slider 67 to slide along the slide rail 66. The slide rail 66 and the slider 67 can limit the movement of the tooth plate 47 to prevent the tooth plate 47 from being misplaced when moving.

[0063] The inner bottom surface of the support box 1 is rotatably connected with a support roller 31 through a bearing, the top surface of the support roller 31 is fixedly connected to the bottom surface of the connection box 2, and a worm wheel 32 is fixedly sleeved on the outer circumferential wall surface of the support roller 31. A bearing seat 28 is fixedly installed on the inner bottom surface of the support box 1, and a worm body 29 is rotatably connected to one side of the bearing seat 28. The bearing seat 28 can support the worm body 29. The worm body 29 is meshed and connected with the worm wheel 32. The unfolded spiral angle of the worm body 29 is smaller than the contact friction angle, which facilitates the self-locking of the worm body 29 and the worm wheel 32. One end of the worm body 29 passes through the support box 1 and is fixedly installed with a knob 30. The rotation of the knob 30 drives the worm wheel 32 to rotate, and the rotation of the worm wheel 32 drives the support roller 31 to rotate. The rotation of the support roller 31 drives the connection box 2 and the base plate 4 to rotate, and the rotation of the base plate 4 drives the telescope group 6 to rotate, thereby adjusting the orientation of the surveying and mapping machine body 5 and the telescope group 6.

[0064] Specifically, by setting up the surveying and mapping body 5, the staff places the surveying and mapping body 5 and the telescope group 6 at a suitable position to monitor the deformation of the building. The staff rotates the knob 30, and the knob 30 rotates to drive the worm body 29 to rotate, and the worm body 29 rotates to drive the worm gear 32 to rotate, and the worm gear 32 rotates to drive the support roller 31 to rotate, and the support roller 31 rotates to drive the connection box 2 and the rubber bushing 3 to rotate, and the connection box 2 and the rubber bushing 3 rotate to drive the base plate 4 to rotate, and the base plate 4 rotates to drive the surveying and mapping body 5 and the telescope group 6 to rotate, thereby adjusting the angle of the surveying and mapping body 5 and the telescope group 6, and then adjusting the orientation of the surveying and mapping body 5 and the telescope group 6;

[0065] Restriction holes 17 are provided on both sides of the fixing box 15, and restriction blocks 18 for preventing the plug-in board 16 from being separated are fixedly installed on both sides of the plug-in board 16. The restriction blocks 18 are slidably connected with the restriction holes 17. The movement of the plug-in board 16 inside the fixing box 15 drives the restriction blocks 18 to move inside the restriction holes 17, thereby preventing the plug-in board 16 from being separated from the fixing box 15.

[0066] Specifically, the plug board 16 is provided, and the plug board 16 moves inside the fixing box 15 to drive the limiting block 18 to move inside the limiting hole 17 on the side of the fixing box 15. The limiting block 18 can limit the movement of the plug board 16 to prevent the plug board 16 from detaching from the fixing box 15.

[0067] A storage box 24 for storing counterweights is fixedly installed on one side of the fixed box 15, a fixing frame 25 is fixedly installed on the top surface of the storage box 24, a threaded rod 27 is threadedly connected to the top surface of the fixing frame 25, a pressing plate 26 is rotatably connected to the bottom surface of the threaded rod 27 through a bearing, and the pressing plate 26 is slidably connected to the storage box 24, and the pressing plate 26 is used to limit the internal counterweights of the storage box 24;

[0068] The bottom surface of the storage box 24 is provided with a rectangular through hole. When the counterweight block inside the storage box 24 needs to be taken out, the staff can put their fingers into the rectangular hole to lift up the counterweight block to take it out. The staff puts the counterweight block into the storage box 24, and the staff rotates the threaded rod 27 to drive the pressing plate 26 to move downward until it abuts against the top surface of the counterweight block inside the storage box 24, thereby restricting the counterweight block inside the storage box 24, thereby increasing the weight of the fixing box 15 and the plug-in board 16, lowering the overall center of gravity, and further improving stability.

[0069] Specifically, through the setting of the plug board 16, the staff will stick one end of the plug board 16 into the soil, and then the staff will put the counterweight block into the storage box 24. The staff will rotate the threaded rod 27 to drive the bearing to rotate while the pressure plate 26 will not rotate. The rotation of the threaded rod 27 will also drive the pressure plate 26 to move downward until it abuts against the configuration block inside the storage box 24, thereby restricting the counterweight block to the inside of the storage box 24, thereby increasing the weight of the fixed box 15 and the plug board 16, lowering the overall center of gravity, avoiding the shaking of the fixed box 15 and the plug board 16, and further improving the stability of the support box 1.

[0070] Working principle: Through the support box 1, the staff puts the support box 1 together with the surveying and mapping machine body 5 and the telescope group 6 in a suitable position, and adjusts the height of the surveying and mapping machine body 5 and the telescope group 6 by adjusting the position of the plug-in board 16 in the fixing box 15 and locking the position of the plug-in board 16 with the screw 20, thereby adjusting the height of the surveying and mapping machine body 5 and the telescope group 6;

[0071] Secondly, the staff rotates the second support rod 12 outward to drive the fixing box 15 and the plug board 16 to rotate outward to a suitable position and put one end of the plug board 16 into the soil. At this time, the fixing box 15, the plug board 16, the connecting block 11 and the second support rod 12 can support the support box 1 to improve the stability of the support box 1;

[0072] At the same time, when the staff member rotates the support rod 2 12 outward, the sliding block 19 slides along the two support rods 2 12, and the sliding of the sliding block 19 drives the support rod 3 22 to rotate, and the rotation of the support rod 3 22 drives the support ring 13 to slide on the support rod 1 9, and the support ring 13 and the support rod 3 22 can limit the rotation of the support rod 2 12. When the support rod 2 12 is rotated to a suitable angle, the staff member uses the screw 14 to lock the position of the support ring 13 on the support rod 1 9. At this time, the support ring 13 and the support rod 3 22 can support the support rod 2 12, reducing the shaking of the support rod 2 12, the fixing box 15 and the plug-in board 16;

[0073] Subsequently, in the follow-up management of the construction project, the staff will use the surveying machine 5 and the telescope group 6 to monitor the deformation of the building and measure its tilt angle. At this time, the base plate 4 may tilt due to the uneven ground. When the gyroscope 40 detects that the base plate 4 is not in a horizontal state, the detected tilt angle will be transmitted to the information processing unit. The information processing unit processes the information and feeds back to the multiple electric push rods 36. The telescopic axes of the multiple electric push rods 36 move outward or retract inward to adjust the angles of the base plate 4, the surveying machine 5 and the telescope group 6, so that the surveying machine 5 and the telescope group 6 remain horizontal, thereby reducing the error in monitoring the deformation of the building.

[0074] Next, the knob 30 rotates to drive the worm gear 32 to rotate, the worm gear 32 rotates to drive the support roller 31 to rotate, the support roller 31 rotates to drive the connection box 2 and the base plate 4 to rotate, the base plate 4 rotates to drive the telescope group 6 to rotate, thereby adjusting the orientation of the surveying and mapping machine body 5 and the telescope group 6;

[0075] Finally, the staff sets the center of the pressure test pad 61 as the reference position, which is on the central axis of the support box 1. When monitoring the deformation of the building, the staff will first adjust the orientation of the surveying and mapping body 5 and the telescope group 6, and then adjust the angle of the telescope group 6. The change in the orientation of the surveying and mapping body 5 and the adjustment of the angle of the telescope group 6 change the overall center of gravity of the surveying and mapping body 5 and the telescope group 6, so that their center of gravity and the center of gravity of the support box 1 are not on the central axis. At this time, the overall center of gravity of the surveying and mapping body 5 and the telescope group 6 is offset from the reference point. The staff turns the knob four 60 to drive the support column 57 and the bevel gear two 58 to rotate, the bevel gear two 58 rotates to drive the bevel gear one 56 to rotate, the bevel gear one 56 rotates to drive the screw rod 54 to rotate, the screw rod 54 rotates to drive the movable block 53 to move, and the movable block 53 moves to drive the surveying and mapping body 5 and the telescope group 6 to move, thereby adjusting the center of gravity of the surveying and mapping body 5 and the telescope group 6 in the horizontal direction;

[0076] On the other hand, when the center of the surveying and mapping body 5 and the telescope group 6 are longitudinally offset from the reference point on the pressure test pad 61, the staff member's knob three 59 drives the double-lead worm 43 to rotate, the rotation of the double-lead worm 43 drives the worm gear two 44 and the spur gear one 45 to rotate, the rotation of the spur gear one 45 drives the gear plate 47 to move, the movement of the gear plate 47 drives the spur gear two 48 to rotate, the rotation of the spur gear two 48 drives the connecting rod one 49 to rotate, the rotation of the connecting rod one 49 drives the connecting rod two 51 to move, thereby allowing the surveying and mapping body 5 and the telescope group 6 to move in the longitudinal direction and then change the center of gravity position of the surveying and mapping body 5 and the telescope group 6 in the longitudinal direction, further improving the accuracy of monitoring the deformation of the building.

[0077] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
