DETAILED DESCRIPTION

[0027] To make the purposes, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application are clearly and completely described below. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0028] As shown in Figures 1 to 8 the present application provides a leveling device for wind turbine foundation construction, which comprises a tripod 1, the tripod 1 comprises a triangular plate 11 and a foot tube 12 rotatably installed on three faces of the triangular plate 11, the bottom of each group of foot tubes 12 is movably installed with an extension support plate 13, and the top of the tripod 1 is provided with a total station assembly 2.

[0029] The bottom of each group of extension support plates 13 is provided with a support mechanism 3, the support mechanism 3 comprises a hinged block 31 rotatably installed at the bottom of the extension support plate 13, the bottom of the hinged block 31 is fixedly installed with a support foot 32, the bottom of the support foot 32 is fixedly installed with a rubber pad 33, the inside of the support foot 32 is provided with a sliding slot 34, the sliding slot 34 is slidably installed with a moving plate 35, the bottom of the moving plate 35 is fixedly installed with a pointed foot 36, the bottom of the support foot 32 and the rubber pad 33 are provided with through holes for displacement of the pointed foot 36, the outer wall of the through hole at the bottom of the support foot 32 is fixedly installed with a scraper 37, the scraper 37 can be mutually attached to the outer wall of the pointed foot 36, the outer wall of the support foot 32 is provided with a guide slot 39, one end of the moving plate 35 penetrates to the outside of the support foot 32 through the guide slot 39 and is fixedly connected with a control plate 38.

[0030] In use, the worker first unfolds the three groups of foot pipes 12, and then makes the bottoms of the three groups of supporting feet 32 and the ground mutually abut, to realize supporting operation, at which time the worker can adjust the extension support plates 13 according to the levelness of the total station assembly 2. After the adjustment is completed, in order to avoid the vibration generated during the construction of the mechanical and electrical equipment or the fan foundation from causing the supporting feet 32 to deviate, the worker can control the moving plate 35 to be kicked down along the sliding groove 34, and the further pointed feet 36 will be downward and pass through the holes of the supporting feet 32 and the rubber pads 33, and finally the pointed feet 36 are inserted into the soil, to realize the fixation of the supporting feet 32. At this time, the pointed feet 36 penetrate into the soil to reinforce the supporting feet 32, and the design of the rubber pads 33 at the bottoms of the supporting feet 32 will increase the friction between the supporting feet 32 and the ground, and the material characteristics of the rubber pads 33 can absorb the vibration. After the leveling operation is completed, the worker resets the moving plate 35 upward, so that the pointed feet 36 are stored in the supporting feet 32, and the scraper plate 37 can scrape off the soil on the outer wall of the pointed feet 36 when the pointed feet 36 are stored.

[0031] Through the arrangement of the three groups of extension support plate 13 bottom supporting mechanisms 3, the supporting feet 32 have a larger contact area with the ground than the conventional pointed feet, can ensure the stability of the supporting mechanism 3 through the friction, and can further absorb the vibration transmitted by the ground through the material characteristics of the rubber pads 33. Then, the pointed feet 36 can be controlled to be moved downward, so that the pointed feet 36 are inserted into the soil, to complete secondary fixation and improve the stability during leveling of the total station. Finally, the device can also store the pointed feet 36, and can scrape off the soil on the outer wall of the pointed feet 36 when the pointed feet 36 are stored, thereby improving the safety performance of the device and reducing the burden of leveling.

[0032] Each group of supporting mechanisms 3 is internally provided with a fixing mechanism 4;

[0033] The fixing mechanism 4 comprises two groups of telescopic holes 42 respectively arranged on the upper and lower ends of the inner wall of the supporting feet 32, two groups of telescopic holes 42 are internally movably installed with inclined wedges 43, one end of the inclined wedge 43 is elastically connected between the inner wall of the telescopic hole 42 through the first spring 44; the outer wall of the moving plate 35 is provided with a fixing hole 41, the positions of the fixing hole 41 and the telescopic hole 42 correspond to each other, the other end of the inclined wedge 43 can penetrate into the inside of the fixing hole 41 and abut against the fixing hole 41. The moving plate 35 is movably installed with a transmission rod 47, one end of the transmission rod 47 penetrates into the control plate 38, and the other end penetrates into the inside of the fixing hole 41.

[0034] In the initial state, the movable plate 35 is located at the upper end of the support foot 32 and is fixed to the support foot 32 through the upper telescopic hole 42, the wedge 43, and the telescopic hole 42. When the worker needs to control the pointed foot 36 to insert into the ground, the worker controls the transmission rod 47 to move, that is, to move towards the telescopic hole 42. The transmission rod 47 further compresses the wedge 43, causing the wedge 43 to be retracted into the telescopic hole 42. At this time, the fixed relationship between the support foot 32 and the movable plate 35 is released, and the worker can step down on the control plate 38 to insert the pointed foot 36 into the soil. When the movable plate 35 moves down and touches the wedge 43 located in the lower telescopic hole 42, the wedge 43 will be retracted into the telescopic hole 42. Further, when the fixing hole 41 of the movable plate 35 is aligned with the telescopic hole 42, the wedge 43 will be pushed into the fixing hole 41 under the elastic action of the first spring 44, thereby fixing the movable plate 35 to the lower end of the support foot 32, making the pointed foot 36 more stable after being inserted into the soil.

[0035] The control panel 38 has a button 45 installed inside it. One end of the button 45 extends to the outside of the control panel 38, and the other end of the button 45 is fixedly connected to one end of the transmission rod 47. It is also elastically connected to the inner wall of the control panel 38 by a second spring 46.

[0036] When the operator controls the displacement of the pointed foot 36, the operator first presses the button 45 inward. The button 45 drives the transmission rod 47 to move inward simultaneously. The transmission rod 47 further compresses the wedge 43, causing the wedge 43 to retract into the telescopic hole 42. At this point, the fixed relationship between the support foot 32 and the moving plate 35 is released. After the operator releases the button 45, the transmission rod 47 will reset due to the elastic potential energy of the second spring 46, and the wedge 43 will re-enter the fixed hole 41 due to the elastic potential energy of the first spring 44, completing the fixation.

[0037] The total station component 2 includes a connecting seat 21 installed on the top of the triangle plate 11, an adjusting seat 22 is provided on the top of the connecting seat 21, and the total station 23 is provided on the top of the adjusting seat 22.

[0038] It should be noted that a foot screw is provided between the connecting seat 21 and the adjusting seat 22, and the operator can adjust the total station 23 by rotating the foot screw.

[0039] The connecting seat 21 has an expansion groove 24 on its outer edge. A protective plate 25 is movably installed inside the expansion groove 24. A protruding plate 26 is fixedly installed on the outer wall of the protective plate 25. A first magnetic block 27 is fixedly installed on the top of the protective plate 25. A second magnetic block 28 is fixedly installed on the bottom of the adjusting seat 22. The first magnetic block 27 and the second magnetic block 28 are magnetically attracted to each other.

[0040] After the staff has adjusted the position, the convex plate 26 can be pulled upwards. The convex plate 26 will cause the protective plate 25 to move upwards. Furthermore, when the protective plate 25 moves upwards to its maximum value, the first magnetic block 27 and the second magnetic block 28 at the top of the protective plate 25 will be attracted magnetically, so that the protective plate 25 will protect the foot screw inside, preventing the staff from accidentally touching it during measurement.

[0041] By pulling the protective plate 25 upward, the first magnetic block 27 and the second magnetic block 28 are brought closer together. After they are close enough, the first magnetic block 27 and the second magnetic block 28 attract each other magnetically, thus fixing the protective plate 25. Compared with traditional devices, this device can prevent workers from accidentally touching the protective plate 25 after the foot screw is adjusted, thus avoiding the increased workload caused by multiple adjustments.

[0042] A fixing shell 14 is fixedly installed on the outer wall of the foot tube 12. A fastening bolt 15 is threaded onto the outer wall of the fixing shell 14. One end of the fastening bolt 15 abuts against the extension support plate 13. During actual operation, the operator can extend or shorten the extension support plate 13. After the extension support plate 13 reaches the appropriate length, the fastening bolt 15 is rotated to fix the extension support plate 13.

[0043] The working principle and usage process of this application:

[0044] When in use, the staff first unfolds the three sets of foot tubes 12, and then makes the bottom of the three sets of support feet 32 ​​fit together with the ground to achieve support operation. At this time, the staff can adjust the extension plate 13 according to the level of the total station component 2. The staff can extend the extension plate 13, and after the extension plate 13 reaches the appropriate length, rotate the fastening bolt 15 to fix the extension plate 13. After adjustment, to prevent the support foot 32 from shifting due to vibrations generated during the construction of electromechanical equipment or wind turbine foundations, the worker can use the control panel 38 to move the movable plate 35 downwards along the slide 34. At this time, when the worker controls the displacement of the pointed foot 36, the worker first steps inwards on the button 45. The button 45 drives the transmission rod 47 to move synchronously. The transmission rod 47 further compresses the wedge 43, causing the wedge 43 to be retracted into the interior of the telescopic hole 42. At this time, the fixed relationship between the support foot 32 and the movable plate 35 is released. The worker can then step down on the control panel 38. The pointed foot 36 will then move downwards and through the holes opened in the support foot 32 and the rubber pad 33, finally inserting the pointed foot 36 into the soil, thus fixing the support foot 32. At this time, the pointed foot 36 penetrates into the soil to reinforce the support foot 32. The design of the rubber pad 33 at the bottom of the support foot 32 increases the friction between the support foot 32 and the ground. The material properties of the rubber pad 33 absorb vibration. After the leveling operation is completed, the workers reset the moving plate 35 so that the pointed foot 36 is stored inside the support foot 32. When the pointed foot 36 is stored, the scraper 37 will scrape off the soil on the outer wall of the pointed foot 36.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
