Description

Technical Field

[0001] The utility model relates to the technical field of fan foundation steel templates, in particular to a fan foundation steel template installation and positioning device. Background Art

[0002] Independent extended foundations are the most common form of wind turbine foundation and are widely used in domestic onshore wind farms. The wind turbine foundation construction process primarily includes topsoil removal, mechanical excavation, manual bottom cleaning and compaction, cushion construction and embedded component installation, reinforcement and anchor assembly leveling, formwork support, and concrete curing. Formwork support, concrete pouring, and curing are key factors affecting wind turbine foundation quality.

[0003] At present, it is common to use standardized steel formwork as support formwork in wind turbine foundation construction. Steel cables are added to the outside of the standardized steel formwork to provide secondary protection for the steel formwork. The steel formworks are connected and enclosed by bolts and steel cables.

[0004] During the concrete pouring process, the steel formwork is subjected to the outward expansion force of the concrete, causing it to move outward. Stress is concentrated at the bolted joints, which can easily cause deformation of the steel formwork. Furthermore, when installing the steel formwork, if two adjacent steel formworks are installed vertically and offset, resulting in a large difference in relative position between the two adjacent steel formworks, it is more likely to cause deformation at the joints, resulting in serious consequences such as leakage and formwork explosion. Utility Model Content

[0005] In view of this, the utility model aims to propose a fan foundation steel formwork installation and positioning device, which can make the installation positions of two adjacent steel formworks tend to the same horizontal plane, strengthen the connection strength between the two adjacent steel formworks, and improve the connection stability between the steel formworks.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the utility model is achieved as follows:

[0007] A wind turbine foundation steel formwork installation and positioning device comprises a plurality of positioning units arranged vertically, wherein the positioning units comprise a crossbar and two positioning groups arranged on the same side of the crossbar;

[0008] The two groups of positioning groups are arranged opposite to each other, and the positioning groups include two positioning blocks and a first bolt provided on the positioning blocks. The two positioning blocks are arranged up and down and have a positioning gap. The positioning gap is arranged parallel to the cross bar. The first bolt passes through the positioning block horizontally and cooperates with the corresponding positioning block thread.

[0009] Furthermore, it also includes an adjustment unit, which is arranged on the crossbar on the positioning unit at the top;

[0010] The adjustment unit includes a mounting plate vertically connected to the cross bar, a slider sleeved on the mounting plate, a mounting block provided on the top of the mounting plate, a second bolt threaded through the mounting block, and a connecting column connected between the second bolt and the slider, one end of the connecting column is fixedly connected to the side surface of the mounting block, and the other end is provided with a blind hole, the inner wall of the blind hole is provided with a circumferential groove along the circumference, the threaded end of the second bolt extends into the blind hole and is fixedly connected to a matching block that slides in cooperation with the circumferential groove, an adjustment groove is provided on the side surface of the slider on the same side as the positioning gap, and the adjustment groove is arranged parallel to the cross bar.

[0011] Furthermore, a plurality of through holes are formed on the screw head end of the second bolt along the circumferential direction.

[0012] Furthermore, there are two positioning units, and a plurality of reinforcing ribs are fixedly connected between the two positioning units.

[0013] Furthermore, the positioning unit also includes two anti-slip blocks mounted on the cross bar, the anti-slip blocks are arranged on the outside of the positioning block, and a connecting rod is fixedly connected between the anti-slip blocks on the same side of the cross bar of the two positioning units, and a fastening unit is connected between the two connecting rods.

[0014] Furthermore, the fastening unit includes a sleeve and a screw, the first end of the sleeve is fixedly connected to the inner side of one of the connecting rods, the threaded end of the screw passes through the other connecting rod and is threadedly connected to the second end of the sleeve, and the screw head end of the screw abuts against the side wall of the corresponding connecting rod.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] The fan foundation steel formwork installation and positioning device of the present invention installs two adjacent steel formworks on the same horizontal plane through two horizontally arranged positioning gaps, avoiding the vertical misalignment of the two adjacent steel formworks. The first bolts on the positioning block are then abutted against the ribs on the steel formwork. The first bolts of the two positioning groups simultaneously apply pressure to the middle of the two adjacent steel formworks, thereby improving the connection strength between the two adjacent steel formworks and reducing the risk of leakage and bursting of the steel formworks.

[0017] Furthermore, when installing the steel cable that strengthens the connection strength of the steel formwork, the steel cable is placed in the adjustment groove of the slider. Before, during and after the concrete pouring, the position of the slider can be adjusted at any time through the second bolt, that is, the steel cable is pushed to move by the slider to adjust the position of the steel cable so that the steel cable can always be in a horizontal position with the connection point of the steel formwork, which can better strengthen the connection strength between the two adjacent steel formworks.

[0018] Secondly, the two anti-slip blocks on the cross bar are squeezed toward the middle through the fastening unit, so that the anti-slip blocks fit tightly with the first bolt, which can prevent the first bolt from loosening, further strengthen the extrusion force of the first bolt on the steel formwork, and ultimately improve the connection strength between the two adjacent steel formworks.

[0028] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features therein can be combined with each other.

[0029] In the description of the present invention, it should be noted that if terms such as "upper", "lower", "inner", and "back" appear to indicate orientation or positional relationships, they are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as a limitation on the present invention. If terms such as "first" and "second" appear, they are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0030] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0031] This embodiment relates to a wind turbine foundation steel template installation and positioning device, an exemplary structure of which is as follows: Figure 1-6 shown.

[0032] Overall, if Figure 1-2 As shown, the wind turbine foundation steel template installation and positioning device includes a plurality of positioning units arranged vertically, and the positioning unit includes a cross bar 1 and two positioning groups arranged on the same side of the cross bar 1.

[0033] The two positioning groups are arranged opposite each other, each comprising two positioning blocks 2 and first bolts 3 mounted on the positioning blocks 2. The threaded ends of the first bolts 3 on both sides of the crossbar 1 are both facing inward. The two positioning blocks 2 are arranged vertically and have a positioning gap 4. The positioning gap 4 is arranged parallel to the crossbar 1. The first bolts 3 pass horizontally through the positioning blocks 2 and engage with the corresponding threaded positioning blocks 2.

[0034] During installation, since there are multiple crisscrossing ribs in the middle of the steel formwork, one of the transverse ribs is placed in the positioning gap 4 of one of the positioning groups, and the transverse ribs 21 on the other steel formwork are placed in the positioning gap 4 of the other positioning group. In this way, the two adjacent steel formworks can be positioned at the same horizontal position, avoiding excessive misalignment of the two adjacent steel formworks.

[0035] In this embodiment, if Figure 3As shown, it also includes an adjustment unit, which is arranged on the crossbar 1 on the top positioning unit. As an exemplary structure of the adjustment unit, it includes a mounting plate 5 vertically connected to the crossbar 1, a slider 6 sleeved on the mounting plate 5, a mounting block 7 arranged on the top of the mounting plate 5, a second bolt 8 threaded through the mounting block 7, and a connecting column 9 connected between the second bolt 8 and the slider 6. One end of the connecting column 9 is fixedly connected to the side of the mounting block 7, and the other end is provided with a blind hole 10. The inner wall of the blind hole 10 is provided with a circumferential groove 11 along the circumference. The threaded end of the second bolt 8 extends into the blind hole 10 and is fixedly connected to a matching block 12 that slides with the circumferential groove 11. The side of the slider 6 on the same side as the positioning gap 4 is provided with an adjustment groove 13, and the adjustment groove 13 is arranged parallel to the crossbar 1.

[0036] Among them, Figure 5 、 6 As shown, the mounting plate 5 is installed perpendicular to the crossbar 1, the mounting block 7 is set horizontally to the crossbar 1, and the threaded end of the second bolt 8 is then passed through the mounting block 7 and installed with the connecting column 9. During use, by rotating the second bolt 8, under the action of the mounting block 7, the second bolt 8 moves back and forth along the length of the mounting plate 5, thereby pushing the slider 6 to move back and forth, and finally pushing the steel cable on the steel template through the adjustment slot 13 of the slider 6 to move, adjusting the position of the steel cable so that the steel cable can be in a horizontal position at the connection with the steel template. In addition, when the second bolt 8 rotates, the threaded end of the second bolt 8 rotates in the blind hole 10. Due to the action of the matching block 12 and the slide groove on the second bolt 8, the second bolt 8 can rotate in the blind hole 10 and push the slider 6 back and forth through the connecting column 9, without the second bolt 8 being disengaged from the connecting column 9.

[0037] Secondly, the screw head end of the second bolt 8 is provided with a plurality of through holes 14 along the circumferential direction. A steel bar or other long hard object can be inserted into the through hole 14 to rotate the second bolt 8. This can save time and effort and make it more convenient to rotate.

[0038] In this embodiment, there are two positioning units, and a plurality of reinforcing ribs 15 are fixedly connected between the two positioning units. The reinforcing ribs 15 improve the connection strength between the two adjacent positioning units, and after the two positioning units are connected as one, the connection strength between the two adjacent steel formworks can be better strengthened.

[0039] The positioning unit also includes two anti-slip blocks 16 sleeved on the crossbar 1. The anti-slip blocks 16 are located outside the positioning block 2. A connecting rod 17 is fixedly connected between the anti-slip blocks 16 on the same side of the crossbar 1 of the two positioning units, and a fastening unit is connected between the two connecting rods 17. Two upper and lower connecting blocks 20 are fixedly connected to the anti-slip blocks 16. The gap between the two connecting blocks 20 allows the ribs to pass through, and the ends of the connecting blocks 20 can better contact the bolt heads of the first bolts 3, increasing the contact area between the two.

[0040] As an exemplary structure of the fastening unit, it includes a sleeve 18 and a screw 19. The first end of the sleeve 18 is fixedly connected to the inner side of one of its connecting rods 17. The threaded end of the screw 19 passes through the other connecting rod 17 and is threadedly connected to the second end of the sleeve 18. The screw head end of the screw 19 abuts against the side wall of the corresponding connecting rod 17.

[0041] The working process of this embodiment is as follows:

[0042] The following text will explain the left and right steel formwork.

[0043] First, place the left and right steel templates in their installation positions. Then, position the positioning gaps 4 on both sides of the crossbar 1 in this embodiment over the transverse ribs 21 at the same height on the left and right steel templates, and pass the ribs through the positioning gaps 4. This will ensure that the left and right steel templates are in a horizontal position. When there are two or more positioning units, the method is the same as above: pass the transverse ribs 21 through the corresponding positioning gaps 4 to ensure that the left and right steel templates are in a horizontal position.

[0044] Then, tighten the first bolt 3 so that the threaded end of the first bolt 3 presses against the longitudinal ribs 22 connected to the transverse ribs 21, and press the first bolts 3 on the positioning groups on the left and right sides of the crossbar 1 inward to tighten the longitudinal ribs 22, so that the left and right steel templates can be connected together.

[0045] When installing the steel cable, turn the second bolt 8 so that the second bolt 8 carries the slider 6 upward, and the position of the slider 6 passes the top of the steel formwork, then place the steel cable in the adjustment slot 13, and then drive the steel cable downward through the second bolt 8 and the slider 6, and finally carry the steel cable to the height of the connection between the left and right steel formworks. During the concrete pouring process, if the position of the steel cable is found to be offset, the position of the steel cable can be changed by turning the second bolt 8 so that the steel cable is always at the height of the connection between the left and right steel formworks, thereby improving the fastening effect of the steel cable on the two steel formworks. It should be noted that after the steel cable is offset, the steel cable can be moved by turning the second bolt 8 with greater force.

[0046] Finally, after adjusting the position of the steel cable, the screw 19 is rotated, the screw 19 moves in the sleeve 18, and the anti-slip block 16 is moved through the connecting rod 17, and finally the connecting block 20 on the anti-slip block 16 is pressed against the screw head end of the first bolt 3 to prevent the first bolt 3 from loosening.

[0047] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
