Description

Technical Field

[0001] The present invention relates to the technical field of engineering cost surveying and mapping, and specifically to an engineering cost surveying and mapping method. Background Technique

[0002] Engineering cost refers to the total construction price of all expected or actual required costs during the construction period of a project. When existing engineering cost technicians conduct on-site surveying and mapping, they usually use devices such as total stations and levels to survey parameters such as height and coordinate positions, so as to facilitate the calculation of engineering costs.

[0003] The support frames used in existing surveying and mapping devices are usually tripods. During actual surveying and mapping, when the surveying height of the surveying instrument needs to be adjusted, it is necessary to separately adjust the lengths and bending angles of the three legs of the tripod. The adjustment of height and levelness is more troublesome, and reciprocating fine-tuning is required during actual use, which is not conducive to use.

[0004] And after the surveying height of the surveying instrument is adjusted, it is usually necessary to adjust the surveying angle of the surveying instrument according to different surveying targets in the project. The traditional adjustment method of directly manually carrying the tripod of the surveying instrument will also cause the surveying instrument to shake, which is prone to surveying errors during the engineering cost surveying and mapping process.

[0041] Embodiment 1: Please refer to Figures 1 to 9 , the present invention provides a technical solution: A method for engineering cost surveying and mapping is as follows:

[0042] Move the surveying instrument 2 to the position where engineering cost surveying and mapping is required. Then deflect the three limit frames 7 to an appropriate angle, pull out the support frame 8 and fix the protection housing 1 to the ground through the fixing block 12, and lock the support frame 8 on the limit frame 7 through the locking pin 11 to complete the fixation of the surveying instrument 2 at the engineering cost surveying and mapping position;

[0043] First, pull the handle 10 outwards, and then rotate the handle 10 around the center of the rotating plate 9. Under the meshing action of the second gear 31 and the third gear 19, drive the moving column 30 to perform circular motion on the surface of the third gear 19, so that the piston rod 23 and the piston plate perform piston motion in the piston cylinder 26, input the outside air into the three sleeves 4, and under the action of the air pressure in the sleeves 4, push the connecting column 5 to drive the surveying instrument 2 to move upwards step by step;

[0044] When the surveying height of the surveying instrument 2 is adjusted, control the electric push rod 38 to contract until the second gear 31 meshes with the fourth gear 33. At this time, the abutting block 47 on the surface of the moving block 39 will press the second button 46, and the indicator light 24 will flash blue light;

[0045] Similarly, first pull out the rotating plate 9 and then move the handle 10 to drive the first rotating shaft 32 to rotate. Under the transmission action of the second gear 31, the fourth gear 33, the worm gear 51 and the worm 50, rotate the mounting disk 6 and the surveying instrument 2 above it to complete the adjustment of the surveying angle of the surveying instrument 2;

[0046] At this time, the indicator light 24 will flash blue light, which can remind the operator beside the surveying target to cooperate with the subsequent surveying operations;

[0047] Operate the controller on the surveying instrument 2 to control the surveying instrument 2 to perform surveying work, and the surveying results will be stored in the controller.

[0048] It should be noted that in the method for engineering cost surveying and mapping, the protection housing 1 is adopted. The lower surface of the protection housing 1 is fixedly connected with a fixing disk 3. The lower surface of the fixing disk 3 is provided with a plurality of fixing cones. The upper surface of the fixing disk 3 is fixedly connected with the protection housing 1. The surface of the protection housing 1 is fixedly connected with a sleeve 4. The inner wall of the sleeve 4 is slidably connected with a connecting column 5. The upper surface of the connecting column 5 is fixedly connected with a connecting disk 13. The upper surface of the connecting disk 13 is rotatably connected with a mounting disk 6 through a fixed shaft. The surveying instrument 2 is fixedly installed on the mounting disk 6, and a controller is provided on the surveying instrument 2;

[0049] A limiting frame 7 is provided on the surface of the protective housing 1. A support frame 8 is slidably connected to the inner wall of the limiting frame 7. A fixing block 12 is fixedly connected to the end of the support frame 8. A locking pin 11 is provided on the limiting frame 7. An adjusting component and an auxiliary component are provided in the protective housing 1.

[0050] More specifically, when this embodiment is in use: As Figure 1 shown, first move the protective housing 1 and the surveying instrument 2 above it to the position where engineering cost surveying is required. Then deflect the three limiting frames 7 to an appropriate angle, pull out the support frame 8 to an appropriate length, and fix the protective housing 1 to the ground through the fixing block 12. Then lock the support frame 8 on the limiting frame 7 through the locking pin 11, and the protective housing 1 and the surveying instrument 2 can be fixed at the position where engineering cost surveying is required. By operating the controller on the surveying instrument 2, subsequent surveying work can be carried out, and the survey results will be stored in the controller. This is a relatively mature existing technology in the field of surveying instruments and will not be described in detail here.

[0051] Furthermore, the adjusting component includes a support plate provided on the inner wall of the protective housing 1. An electric push rod 38 is fixedly installed on the lower surface of the support plate. The telescopic end of the electric push rod 38 is fixedly connected to a moving block 39. A notch for the moving block 39 to slide and fit is provided on the surface of the protective housing 1. A hollow column 44 is fixedly connected to the surface of the moving block 39. A rotating shaft one 32 is rotatably connected to the surface of the hollow column 44. A plurality of protrusions one 45 distributed in a circumferential array are fixedly connected to the surface of the rotating shaft one 32;

[0052] It also includes a sleeve 40. The sleeve 40 is sleeved on the outer surfaces of the plurality of protrusions one 45 and the rotating shaft one 32. A connecting ring is rotatably connected to the surface of the sleeve 40. A spring one 43 is jointly provided between the connecting ring and the inner wall of the hollow column 44. A gear one 41 is fixedly connected to the surface of the sleeve 40. An internal gear ring 42 meshing with the gear one 41 is fixedly connected to the inner wall of the hollow column 44. A rotating plate 9 is fixedly connected to the end of the sleeve 40. Two symmetrically arranged grips 10 are fixedly connected to the surface of the rotating plate 9. Anti-slip patterns are provided on the surfaces of the two grips 10.

[0053] The end of the rotating shaft one 32 is fixedly connected to a gear two 31. A rotating shaft two 29 is rotatably connected to the inner wall of the protective housing 1. A gear three 19 meshing with the gear two 31 is fixedly connected to the surface of the rotating shaft two 29. A moving column 30 is fixedly connected to the surface of the gear three 19. A moving frame 28 is slidably connected to the outer surface of the moving column 30;

[0054] The inner wall of the protective housing 1 is fixedly installed with a piston cylinder 26. A piston plate is slidably connected to the inner wall of the piston cylinder 26. A piston rod 23 is fixedly connected to the surface of the piston plate. The end of the piston rod 23 is fixedly connected to a connecting plate 22. A connecting rod 20 is fixedly connected to the surface of the moving frame 28. The end of the connecting rod 20 is fixedly connected to a clamping block 21. The connecting plate 22 extends into the inner wall of the clamping block 21 and abuts against it. A sliding groove for the connecting plate 22 to extend out and slide is formed in the inner wall of the protective housing 1. A limiting rod 18 is fixedly connected to the inner wall of the sliding groove. The limiting rod 18 penetrates through the connecting plate 22 and is slidably connected to it. A second spring 17 is jointly arranged between the connecting plate 22 and the inner wall of the sliding groove;

[0055] The inner wall of the protective housing 1 is fixedly installed with a hollow ring 15. An air delivery pipe 27 is fixedly communicated between the hollow ring 15 and the piston cylinder 26. An air inlet pipe 25 is fixedly communicated with the surface of the piston cylinder 26.

[0056] In this embodiment, when it is necessary to raise the surveying instrument 2 to perform surveying work at different heights, hold the two grips 10, and then first pull the rotating plate 9 outward. As the rotating plate 9 moves, the sleeve 40 can be synchronously moved. As the sleeve 40 moves, the gear one 41 can be moved to a position disengaged from the internal gear ring 42. At the same time, the first spring 43 will be stretched. At this time, the sleeve 40 can be rotated in the hollow column 44.

[0057] Then rotate the two grips 10 with the center of the rotating plate 9 as the axis. As the two grips 10 rotate, the rotating plate 9 and the sleeve 40 can be driven to rotate synchronously. Since the sleeve 40 is sleeved on the outer surfaces of a plurality of first protrusions 45 and the first rotating shaft 32, the rotation of the sleeve 40 will drive the first rotating shaft 32 to rotate synchronously at this time.

[0058] As Figure 4 and Figure 6 shown, as the first rotating shaft 32 rotates, under the meshing action of the second gear 31 and the third gear 19, the rotation of the first rotating shaft 32 will drive the third gear 19 to rotate synchronously. Thus, the moving column 30 can perform a circular motion on the surface of the third gear 19. Since the moving frame 28 is limited by the connecting plate 22 and can only move in the vertical direction, the movement of the moving column 30 will cause the moving frame 28 to perform a reciprocating movement in the vertical direction at this time. As the moving frame 28 moves, the connecting plate 22 will be driven to perform a reciprocating movement in the vertical direction.

[0059] Furthermore, a first one-way valve is arranged on the surface of the air inlet pipe 25. A second one-way valve is arranged on the surface of the air delivery pipe 27. An air discharge pipe 48 is fixedly communicated with the surface of the hollow ring 15. An electromagnetic valve 49 is arranged on the surface of the air discharge pipe 48.

[0060] As Figure 3As shown, at this time, the reciprocating movement of the connecting plate 22 will cause the two piston rods 23 to drive their corresponding piston plates to perform piston movement in the piston cylinder 26, so that the outside air can be inhaled from the air inlet pipe 25 and discharged into the hollow ring 15 from the air delivery pipe 27. Since the air discharge pipe 48 is in a closed state at this time, the air accumulated in the hollow ring 15 will enter the three sleeves 4 and continuously accumulate. Under the action of the air pressure in the three sleeves 4, the three connecting columns 5 can be pushed to move upward gradually, so that the connecting disk 13 can drive the mounting disk 6 to move upward gradually, so as to complete the adjustment of the surveying height of the surveying instrument 2. After the height of the surveying instrument 2 is adjusted, the user only needs to release the two grips 10. Under the action of the elastic potential energy of the first spring 43, the gear 41 on the surface of the sleeve 40 can be reset to the position meshing with the internal gear ring 42 again, so as to complete the self-locking after the height adjustment of the surveying instrument 2. Similarly, by opening the solenoid valve 49 on the surface of the air discharge pipe 48, the height of the surveying instrument 2 can be lowered.

[0061] It should be noted that by driving the surveying instrument 2 to rise and fall by air pressure, the surveying device can be adapted to survey the target objects at different height positions in the project cost surveying. Compared with the traditional method of adjusting the length of the tripod, the operation is simpler. And under the action of air pressure, the surveying instrument 2 rises gradually, which can also ensure that the whole surveying device is more stable and not easy to shake during the height adjustment of the surveying instrument 2. Without repeated leveling, the accuracy of the surveying by the surveying instrument 2 can be guaranteed, which is worthy of popularization and use.

[0062] Embodiment 2, on the basis of the above embodiment: Further, the auxiliary component includes a third rotating shaft 14 fixedly connected to the lower surface of the mounting disk 6. A plurality of second protrusions 36 distributed in a circumferential array are fixedly connected to the outer surface of the third rotating shaft 14. A connecting block 35 is fixedly connected to the surface of the hollow ring 15. A rotating rod 16 is rotatably connected to the surface of the connecting block. A slot for inserting and fitting the third rotating shaft 14 and a plurality of second protrusions 36 is provided in the inner wall of the rotating rod 16.

[0063] A fourth rotating shaft 34 is rotatably connected to the inner wall of the protective housing 1. A fourth gear 33 meshing with the second gear 31 is fixedly connected to the surface of the fourth rotating shaft 34. A housing 37 is fixedly installed on the lower surface of the hollow ring 15. A worm 50 is fixedly connected to the end of the fourth rotating shaft 34 extending into the housing 37. A worm gear 51 meshing with the worm 50 is fixedly connected to the end of the rotating rod 16 extending into the housing 37.

[0064] An abutting block 47 is fixedly connected to the surface of the moving block 39. A button one and a button two 46 are arranged on the inner wall of the protective housing 1. A warning light 24 is arranged on the upper surface of the protective housing 1.

[0065] In this embodiment, as Figure 6 and Figure 7As shown, when the second gear 31 meshes with the third gear 19, the abutting block 47 on the surface of the moving block 39 abuts against the first button at this time. At this time, the first button will transmit a signal to the warning light 24, causing the warning light 24 to flash red light.

[0066] After the surveying height of the surveying instrument 2 is adjusted, first control the electric push rod 38 to contract, driving the moving block 39 to move upward until the second gear 31 meshes with the fourth gear 33. At this time, the abutting block 47 on the surface of the moving block 39 will move to the position where the second button 46 is pressed. At this time, the second button 46 will transmit a signal to the warning light 24, causing the warning light 24 to flash blue light. At this time, the operator beside the surveying target can know that the height adjustment of the surveying instrument 2 has ended.

[0067] Similarly, first pull out the rotating plate 9 and then move the two grips 10 to drive the rotation of the first rotating shaft 32. At this time, under the meshing action of the second gear 31 and the fourth gear 33, the rotation of the first rotating shaft 32 will drive the fourth rotating shaft 34 to start rotating, as Figure 9 shown. Under the transmission action of the worm gear 51 and the worm 50, the rotation of the fourth rotating shaft 34 will drive the rotating rod 16 to rotate synchronously. Since the inner wall of the rotating rod 16 is provided with a slot for inserting and matching the third rotating shaft 14 and multiple second protrusions 36, the rotation of the rotating rod 16 will drive the third rotating shaft 14 to rotate synchronously. As the third rotating shaft 14 rotates, the mounting plate 6 and the surveying instrument 2 above it can be rotated synchronously. Similarly, after the surveying instrument 2 rotates to the surveying position, release the grip 10 to complete the adjustment of the surveying angle of the surveying instrument 2. Compared with the traditional method of directly manually carrying the surveying instrument tripod to adjust the surveying angle, the adjustment is simpler and more convenient. At the same time, it also avoids the overall shaking of the surveying device when adjusting the surveying angle of the surveying instrument 2, thereby improving the accuracy and efficiency of the engineering cost surveying.

[0068] It should be noted that when adjusting the surveying angle of the surveying instrument 2, the warning light 24 will flash blue light to remind the operator beside the surveying target to appropriately deflect or move the surveying target to cooperate with the subsequent surveying operations.

[0069] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
