Description

Technical Field

[0001] The invention relates to the technical field of wind power construction, in particular to a wind power construction foundation mould which has enhanced sealing, improved supporting performance and is portable for installation and disassembly. Background Art

[0002] Wind power foundation mold is an important part of wind power equipment construction. Its quality, mold structure and construction method directly affect the performance and service life of wind power equipment. Wind power foundation mold is a mold used to make wind power base template. It has the advantages of easy use, short production cycle and low cost.

[0003] Wind power foundations are mostly cast-in-place reinforced concrete foundations, such as Figure 1 The figure shows the shape of the existing wind power foundation, which is a pedestal type. The foundation is mainly composed of a mold and poured reinforced concrete. The entire foundation consists of two parts: a base plate and a column. The base plate is circular, and the outer circumference of the base plate and the column needs to be fixed with a foundation mold for concrete pouring.

[0004] The original mold structure is relatively simple, with a smooth circumferential surface on the inside and hollow reinforcement ribs on the outside. It is fixed with a manual hoist and a wire rope outer hoop.

[0005] During mold construction, the mold joints must be tight, but the existing molds are aligned when spliced, and there is a straight joint between the two. This joint is only handled by affixing double-sided tape, but a large amount of concrete slurry is poured into the mold, which can easily cause the concrete slurry to break through the double-sided tape or leak from the gaps. Especially for the mold at the bottom plate, since the bottom plate and the column are pedestal-type, the poured concrete has an impact to automatically flow to the mold. Therefore, the straight mold is more prone to leakage.

[0006] In addition, due to the flow of liquid during concrete pouring and the impact force of the tilted platform on the mold, the mold is easily deformed, broken, or knocked down by stamping, thus affecting the construction quality of the foundation.

[0007] In addition, the mold is currently installed and disassembled manually or by crane, which can easily cause inaccuracies during alignment and installation. After alignment, a large number of tension bolts and external hoop steel bars are required for fixing. A large amount of manual labor is required during disassembly, making installation and disassembly very inconvenient.

[0008] On this basis, the present invention provides a wind power construction foundation mold with enhanced sealing, improved supporting performance, and portable installation and disassembly to solve the above technical problems. Summary of the invention

DETAILED DESCRIPTION

[0034] The above and other technical contents, features and effects of the present invention are described in detail below with reference to the attached Figures 1 to 10 The details of the embodiments will be clearly presented. The contents mentioned in the following embodiments are all based on the drawings in the specification.

[0035] Exemplary embodiments of the present invention will be described below with reference to the accompanying drawings.

[0036] The present invention is a wind power construction foundation mold with enhanced sealing, improved supporting performance, and portable installation and disassembly. It is mainly used for concrete construction and pouring of wind power foundations. The foundation mold is constructed and installed by multiple templates 1 to form a circle. Each individual template 1 is arc-shaped. The general structure of each template 1 includes an inner mold segment 2 and an outer mold segment 3, which are connected as one piece. The inner mold segment 2 has a smooth surface and is used to adhere to concrete and shape the concrete into a circle. The outer mold segment 3 is used to reinforce, support, install and disassemble the inner mold segment.

[0037] An arc-shaped insertion section 4 and a plug-in section 5 are integrally connected at both ends of the template 1 . The insertion section 4 of one template 1 is matched and docked with the plug-in section 5 of another template 1 , and the plug-in section 5 of one template 1 is matched and docked with the insertion section 4 of another template 1 .

[0038] It should be noted that the insertion section 4 is coaxial with the template 1 and has a thickness less than that of the template 1. The insertion section 4 is placed in the middle of the thickness of the template 1. Two insertion blocking grooves 6 and two insertion receiving grooves 7 are provided on the inner and outer sides of the insertion section 4. The two insertion blocking grooves 6 and the two insertion receiving grooves 7 on the same side are staggered, the two insertion blocking grooves 6 on different sides are staggered, and the two insertion receiving grooves 7 on different sides are staggered.

[0039] Similarly, the plug-in section 5 is coaxial with the template 1 and its overall thickness is shorter than that of the template 1, but its position is placed at both ends of the outer side and the inner side of the template 1. Two plug-in blocking grooves 8 and two plug-in receiving grooves 9 are provided on the inner side of the inner side of the plug-in section 5 and the inner side of the outer side. The two plug-in blocking grooves 8 and the two plug-in receiving grooves 9 are staggered, the two plug-in blocking grooves 8 on different surfaces are staggered, and the two plug-in receiving grooves 9 on different surfaces are staggered.

[0040] A plurality of first compression springs 10 are fixed in the insertion blocking groove 6 and the plug-in blocking groove 8, and the first compression spring 10 is fixedly connected with a blocking plate 11, which is partially placed in the insertion blocking groove 6 or the plug-in blocking groove 8, and partially placed in the corresponding plug-in receiving groove 9 or the insertion receiving groove 7.

[0041] It should also be emphasized that the end of the blocking plate 11 that is located outside is an arc-shaped chamfer.

[0042] At the same time, the two ends of the insertion (plugging) blocking groove 6 (8) and the insertion (plugging) receiving groove 7 (9) are chamfered slopes, and the corresponding blocking plate 11 is also a chamfered slope.

[0043] At the joint between the insertion section 4 and the plug-in section 5 , a sealing gasket is mounted at the joint, and the shape of the sealing gasket corresponds to the shape of the plug-in receiving groove 9 and the insertion receiving groove 7 .

[0044] In order to facilitate the fixation and disassembly of the insertion section 4 and the plug-in section 5 and to improve the stability during matching, a first reinforcement hole 12 is opened on the outer side surface of the insertion section 4 and at an end away from the end of the insertion section 4, and a second reinforcement hole 13 is opened on the outer side surface of the plug-in section 5 and at an end close to the end of the plug-in section 5. The second reinforcement hole 13 matches the first reinforcement hole 12, and a reinforcement plate 14 is removed and installed in the first reinforcement hole 12 and the second reinforcement hole 13 to lock the plug-in end 5 and the insertion end 4.

[0045] In order to fix the reinforcement plate 14, a first bolt hole 15 is opened in the reinforcement plate 14 and the corresponding insertion section 4, and a first bolt 16 is installed in the first bolt hole 15; a second bolt hole 16 is opened in the reinforcement plate 14 and the corresponding plug-in section 5 and the corresponding insertion section 4, and a second bolt 17 is installed in the second bolt hole 16.

[0046] Specific embodiments: During the construction of the existing basic mold, since the joint is a linear joint, the joint is only pasted with double-sided tape, which is prone to leakage. However, during the jointing of the basic mold of the present invention, one template 1 is first installed manually or by hoisting, and then the insertion section 4 (plug-in section 5) of the other template 1 is matched to the previous plug-in section 5 (insertion section 4) in sequence.

[0047] More specifically, the sealing gasket is pre-installed on the insertion section 4, and then in the process of the insertion section 4 being inserted into the plug-in section 5, for example, the plug-in section 5 moves toward the insertion section 4, the plug-in section 5 presses down the blocking plate 11 in the insertion section 4, and the insertion section 4 presses down the blocking plate 11 in the plug-in section 5 and then passes through in sequence. When the plug-in section 5 is against the insertion section 4, the blocking plate 11 enters the insertion receiving groove 7 and the plug-in receiving groove 9 respectively. At this time, the insertion section 4 and the plug-in section 5 are sealed and connected (with the sealing gasket). At the same time, the insertion section 4 and the plug-in section 5 form a multi-bend line, and the insertion section 4 and the plug-in section 5 are locked through the blocking plate 11. The insertion section 4 and the plug-in section 5 are locked and cannot be removed, thereby completing the locking that is convenient for installation.

[0048] The sealing line has changed from the original single linear seal to Figure 3 The sealing lines shown are as follows: a1-b1-c1-d1-e1-f1-g1-h1-i1-j1-k1-l1-m1-n1-o1-p1-q1-r1-s1-t1-u 1-v1-w1-x1-y1-z1-a2-b2-c2-d2-e2-f2-g2-h2-i2-j2-k2-l2-m2-n2-o2.

[0049] or a1-b1-c1-d1-e1-f1-g1-h1-i1-j1-k1-l1-m1-n1-o1-p1-q1-r1-s1-t1-u1-v1-w1-x1-y1-z1-a2-b2-c2-d2-e2-f2-g2-h2-i2-j2-k3.

[0050] This instantly transforms the original single seam into an extremely complex sealing line, greatly improving the sealing of the seam and reducing leakage.

[0051] It should be noted that, since the length of the integrally connected insertion section 4 and plug-in section 5 is limited, if the length is too long to improve the sealing circuit, the single plug-in section 4 and insertion section 5 are likely to cause insufficient strength. Therefore, in multiple tests, the combination of two insertion (plug-in) receiving grooves 7 (9) and two insertion (plug-in) blocking grooves 6 (8) is the best performance sealing circuit.

[0052] It should also be noted that the two plug-in (insertion) blocking grooves 8 (6) and the two plug-in (insertion) receiving grooves 9 (7) are cross-arranged to form reverse cross-sealing lines, which can also greatly improve the sealing effect.

[0053] In addition, for the insertion section 4, the insertion (plugging) blocking grooves 6 (8) and the insertion (plugging) receiving grooves 7 (9) on the inner and outer sides are also arranged crosswise, which can ensure the strength of the insertion section 4 and the plugging section 5, otherwise it is easy to cause the strength of some positions to be reduced.

[0054] Therefore, under the arrangement of the two insertion (plugging) blocking grooves 6 (8) and the two insertion (plugging) receiving grooves 7 (9), in combination with the cross arrangement of the two insertion (plugging) blocking grooves 6 (8) and the two insertion (plugging) receiving grooves 7 (9) on the same surface, and the cross arrangement of the two insertion (plugging) blocking grooves 6 (8) and the two insertion (plugging) receiving grooves 7 (9) on different surfaces, not only can the sealing performance be greatly enhanced, but also the installation and fixing can be facilitated.

[0055] It should also be noted that the insertion section 4 and the plug-in section 5 can be docked not only in the left-right direction of the circumferential direction, but also from top to bottom.

[0056] After the insertion section 4 and the plug-in section 5 are matched and docked, the reinforcement plate 14 is inserted into the first reinforcement hole 12 and the second reinforcement hole 13. At this time, the outer circumference of the template 1 is still a complete arc, but at this time, the reinforcement plate 14 reinforces and presses the insertion section 4 and the plug-in section 5 at the same time, and the pressure end of the reinforcement plate 14 is provided with two rows of first bolt holes 15 and second bolt holes 16. The first bolt holes 15 fix the reinforcement plate 14 and the insertion section 4, and the reinforcement plate 14 presses the insertion section 4 and the plug-in section 5, thereby completing the fixation of the insertion section 4 and the plug-in section 5.

[0057] The second bolts 17 directly and completely fix the reinforcing plate 14 , the inserting section 4 and the plug-in section 5 , so that more than twice the multiple safety fixation can be achieved through simply two rows of first bolt holes 15 and second bolt holes 16 .

[0058] At this point, the sealing performance will be greatly improved after the base mold is docked.

[0059] Since the foundation mold is used for enclosure concrete pouring, and the pouring shape is an inclined pedestal shape, in order to improve the strength of the foundation mold during concrete pouring, the foundation mold is supported. Currently, the mold support is mainly through the outer wooden pile support.

[0060] The present invention is that a vertical, overall rectangular support member 18 is fixed on the outer template 3 on the outer side surface of the template 1, a slideway 19 is partially opened on the upper end portion of the support member 18, the bottom of the support member 18 is sealed, and a packaging plate is fixed on the upper part, an upper pressing groove 20 is reserved on the packaging plate, and a lower pressing groove 21 is opened in the solid part of the lower end of the support member 18, and the upper pressing groove 20 and the lower pressing groove 21 are connected, that is, the slideway 19 is only a part, which is about 1 / 2 of the length of the support member 18, and an upper through hole 22 and a lower through hole 23 are respectively opened at both ends of the upper and lower ends of the slideway 19 part.

[0061] A roller 24 is installed in a rolling and sliding manner in the slideway 19. The interior of the two ends of the roller 24 is a cavity with openings. A second spring 25 is fixed to the bottom of the roller 24. A compression column 26 is fixed to the second spring 25. The compression column 26 slides in the roller 24 via a slide rail, so that the compression column 26 can only slide in the roller 24. When the compression column 26 rotates, it drives the roller 24 to rotate together. The compression column 26 is partially placed in the roller 24 and partially placed outside the roller 24. The end surface of the compression column 26 is provided with a first toothed disc 27.

[0062] A locking sleeve 28 is fixed at a corresponding position on the outer side of the lower through hole 23. The interior of the locking sleeve 28 is a cavity, and a locking cylinder 29 is installed inside the cavity. The locking cylinder 29 is provided with a second toothed disc 30 at one end close to the support member 18. The second toothed disc 30 matches the first toothed disc 27. When the first toothed disc 27 and the second toothed disc 30 are connected, the first toothed disc 27 cannot rotate.

[0063] A support sleeve 31 is fixedly sleeved on the roller 24 . The support sleeve 31 is placed at the upper pressing groove 20 . The support sleeve 31 is integrally connected with a support rod 32 of the upper pressing groove 20 and the lower pressing groove 21 .

[0064] It should be noted that initially, the roller 24 is placed at the position of the upper through hole 22 , the compression column 26 passes through the upper through hole 22 and is placed outside, and the support rod 32 is placed at the upper pressing groove 20 and the lower pressing groove 21 , flush with the surface of the support member 18 .

[0065] When the construction of the basic mold is completed, the support rod 32 is rotated upward to the angle of the subsequent inclined support, the support rod 32 is pulled out of the upper pressing groove 20 and the lower pressing groove 21, and then the compression columns 26 on both sides are slid inward, so that the compression columns 26 enter the slide 19 through the upper through hole 22, and then the support rod 32 is pulled downward, and the support rod 32 drives the roller 24 to slide downward in the slide 19. When sliding to the position of the lower through hole 23, the compression column 26 pops outward under the action of the second spring 25, and the compression column 26 enters the locking sleeve 28 after passing through the lower through hole 23. At this time, the first toothed disc 27 is docked with the second toothed disc 30. Since the second toothed disc 30 cannot rotate, the second toothed disc 30 limits the first toothed disc 27 and locks the first toothed disc 27. At the same time, the support rod 32 is supported on the ground, which is convenient for the support rod 32 to support the ground.

[0066] When the template 1 is removed, the compression column 26 is pulled inward, the first toothed disc 27 is disengaged from the second toothed disc 30, and the compression column 26 enters the slideway 19 from the lower through hole 23, and the support rod 32 is used to push the roller 24 upward so that the roller 24 returns to the position of the upper through hole 22. At this time, the compression column 26 passes through the upper through hole 22 again under the action of the second spring 25, and then the support rod 32 is rotated downward to return the support rod 32 to the original position of the upper pressing groove 20 and the lower pressing groove 21.

[0067] The support rod 32 is used to improve the supporting performance of the basic mold and the compressive strength of the basic mold. At the same time, it is integrally connected with the template 1, which is convenient for transportation and operation, and does not require additional supporting templates.

[0068] It should be further explained that, in order to facilitate the pulling of the two compression columns 26, a sliding pull ring 34 is connected to the inner side of each compression column 26 via a connecting rope 33, the pull ring 34 is arranged on the support rod 32, and the connecting rope 33 is placed on the support rod 32 through the upper through hole 22 (lower through hole 23), the slide 19, and the upper pressing groove 20.

[0069] Furthermore, a tightening sleeve 35 is coaxially fixed to the outside of the locking sleeve 28. The locking sleeve 28 and the tightening sleeve 35 are not integrally connected. The interior of the locking sleeve 28 and the tightening sleeve 35 is a hollow cavity with both ends transparent. A bidirectional screw rod 36 with opposite screw threads is rotatably installed between the locking sleeve 28 and the tightening sleeve 35. A rotating drum is fixed in the middle of the bidirectional screw rod 36. The rotating drum is placed between the locking sleeve 28 and the tightening sleeve 35. The threads on the sides are respectively threadedly connected with a locking cylinder 29 and a tightening sleeve 37. The tightening sleeve 35 is slidably installed in the locking sleeve 28. The tightening sleeve 37 is slidably installed in the tightening sleeve 35. A second toothed disc 30 is provided at the end of the locking cylinder 29. The second toothed disc 30 matches the first toothed disc 27. A third toothed disc 38 is provided at the end of the tightening sleeve 37 for locking the subsequent rotating rod 39. A rotating rod 39 is rotatably and slidably provided in the tightening sleeve 35.

[0070] It should be noted that the locking sleeve 28 and the pressing sleeve 35 are fixedly connected by welding to a fixing plate of the outer mold segment 3 .

[0071] Furthermore, a fourth toothed disc 40 is provided at the end of the rotating rod 32, and the fourth toothed disc 40 can match the third toothed disc 38. A transverse prying tube 41 is fixed between the two rotating rods 32, and the interior of the prying tube 41 is a hollow cavity with both ends being transparent.

[0072] It should be noted that in the initial position, the fourth toothed disc 40 is not docked with the third toothed disc 38, and the rotating rod 32 can rotate in the tightening sleeve 35. After the rotating rod 32 is slid, the fourth toothed disc 40 is docked with the third toothed disc 38, and the rotating rod 32 is locked and cannot rotate.

[0073] In order to better realize the cooperation between the locking column 29 and the tightening sleeve 37 and the bidirectional screw rod 36, and realize that the locking column 29 and the tightening sleeve 37 can slide, a sliding hole 42 is opened on the locking sleeve 28 and the tightening sleeve 35, and a sliding column 43 that can slide in the locking sleeve 29 and the tightening sleeve 35 is fixed on the locking column 29 and the tightening sleeve 37, thereby limiting the locking column 29 and the tightening sleeve 37.

[0074] Furthermore, a pressing groove 44 is opened at the upper end of the support member 18. In the initial position, the prying tube 41 is clamped in the pressing groove 44, and then the support rod 32 is pressed on the prying tube 41, and a baffle 45 is rotatably installed on the lower pressing groove 21. One end of the baffle 45 is rotatably installed on one side of the lower pressing groove 21, and the other end of the baffle 45 is disassembled and fastened to the other end of the lower pressing groove 21, so as to lock and fix the support rod 32.

[0075] In order to reinforce the basic mold again, a plurality of locking holes 46 are opened at the upper and lower ends of the outer mold section 3. The locking holes 46 are opened on the rib plate of the outer mold section 3. A coaxial arc-shaped screw 47 is penetrated through the locking holes 46. The end of the screw 47 is tightened with a screw bolt 48, which presses the rib plate of another template 1.

[0076] Further, in order to lock the prying tube 41, the prying tube 41 needs to be locked when it is not in use in the initial position, and needs to be locked when supporting the ground. A tightening hole 49 is provided on the end surface of the tightening sleeve 37, and a clamping groove 50 is provided in the tightening hole 49. A clamping spring 51 is installed in the clamping groove 50. The clamping spring 51 is connected to a clamping block 52. The end of the clamping block 52 is provided with a chamfered surface, wherein the cut surface is at the end away from the support rod 32, that is, the outer side, and the inner part is Vertically, an insertion column 53 is fixed to the end surface of the rotating rod 32, an insertion ring 55 is fixed on the insertion column 53, an arc-shaped insertion head 54 is fixed to the end of the insertion column 53, the insertion head 54 is provided with an embedded groove in the direction close to the insertion ring 55, and a switching head 56 on the insertion column 53 is slidably installed between the insertion head 54 and the insertion ring 55, and both ends of the switching head 56 are beveled surfaces, that is, it is composed of two rings with trapezoidal cross-sections spliced ​​together, and the middle part of the splicing is the highest.

[0077] When it is necessary to lock the prying tube 41, the prying tube 41 is slid into the tightening sleeve 35, so that the third toothed disc 38 and the fourth toothed disc 40 are docked. At the same time, the insertion head 54 enters the tightening hole 49, and the insertion head 54 pushes the clamping block 52 to move into the clamping groove 50, so that the insertion head 54 passes smoothly. At this time, the prying tube 41 is locked and cannot move, thereby achieving the locking of the prying tube 41. When it is necessary to unlock, it continues to slide inward, and the beveled surface of the switching head 56 presses the clamping block 52 to move into the clamping groove 50, so that the switching head 56 passes through the clamping block 52, and then the prying tube 41 is pulled outward to move, and the clamping block 52 pushes the switching head 56 to move toward the insertion head 54, and a part of the switching head 56 enters the embedded groove of the insertion head 54, and then the switching head 56 and the insertion head 54 are together, and the clamping block 52 slides out smoothly along the beveled surface of the switching head 56.

[0078] In a more specific embodiment, after the basic template is docked, the retaining bar 45 is removed, the support rod 32 is rotated upward, the prying tube 41 is flipped outward and rotated downward until it is supported on the ground, the pull ring 34 is pulled, the compression column 26 is pulled into the slide 19, and the support rod 32 is pulled downward. The support rod 32 drives the roller 24 to move downward. When it moves to the position of the lower through hole 23, the compression column 26 enters the locking sleeve 28 through the lower through hole 23 under the action of the second spring 25, and the support rod 32 is rotated to a suitable position to support it on the ground. The first toothed disc 27 matches and docks with the second toothed disc 30 to achieve the locking of the support rod 32, and the support rod 32 cannot rotate.

[0079] At the same time, the prying tube 41 is flipped over and supported on the ground, and double insurance support is achieved through the support rod 32 and the prying tube 41.

At the same time, the third toothed disc 38 and the fourth toothed disc 40 are matched and docked, and are firmly locked, so that the prying tube 41 cannot rotate.

[0081] In order to further lock the first toothed disc 27 and the second toothed disc 30 , the third toothed disc 38 and the fourth toothed disc 40 , the rotating drum is rotated, and the bidirectional screw rod 36 drives the second toothed disc 30 and the third toothed disc 38 to move toward the first toothed disc 27 and the fourth toothed disc 40 to further increase the locking force.

[0082] When the mold needs to be removed, the prying tube 41 is turned upward or at a certain angle to the pressing groove 44, and then the support rod 32 is returned to the upper pressing groove 20 and the lower pressing groove 21, and then locked with the blocking bar 45. After that, a prying rod (removal tool) is inserted into one end or both ends of the prying tube 41 or penetrated horizontally to shake and pry upward. It can also be disassembled upward together with a crane, or it can be disassembled in the left and right directions after passing through the prying tube. That is, the template 1 can be disassembled in two ways: left and right directions and upward.

[0083] It should be noted that when removing the template 1, it is necessary to release the first bolt 16, the second bolt 16, the reinforcing plate 14, the screw 47, the screw bolt 48, etc. in advance, and the blocking plate 11 is set at an inclined arc, so it can be removed by prying it horizontally or lifting it upward.

Special personnel are assigned to protect the embedded temperature measuring wires to prevent damage during concrete pouring. The upper, middle and lower three layers of temperature measuring points are arranged as a group. After the large volume of concrete is poured, it must be monitored to detect the surface temperature of the concrete and the temperature of the center of the structure. In order to take corresponding measures to ensure the construction quality of the concrete. When the temperature difference between the inside and the surface of the concrete exceeds 25°C, emergency measures such as deepening the watering curing layer of the concrete should be taken in time to increase the surface temperature of the concrete, reduce the temperature difference between the inside and the outside, and avoid cracks due to excessive temperature difference.
