Description

Technical Field

[0001] The invention relates to the field of power equipment foundation engineering, and in particular to a transmission tower clip-on anchor bolt. Background Art

[0002] Transmission towers are usually composed of three parts: tower head, tower body and tower legs. The towers are generally made of angle steel, steel pipes, steel plates, etc., and are assembled by bolts, welding, etc. Since the tower is a structure with a large slenderness ratio, it is necessary to ensure that the tower has sufficient anti-overturning, anti-settling and anti-uplift capabilities under external load conditions such as icing, dancing, and strong winds. This ability is concentrated in the bearing capacity and stability of the tower foundation. The anchor bolts play an important role in connecting the tower and the foundation and connecting the upper and lower parts in the transmission and distribution lines, which is related to the safe operation of the entire line.

[0003] With the rapid construction of UHV lines, the UHV line network has been densely spread in every corner. The higher the line voltage level, the higher the line height. In order to ensure the stability of the tower and reduce the construction cost, the tower foundation often adopts a split structure, and the root gap between the two foundations is often more than 10m. However, this structure is very disadvantageous under uneven surface settlement.

[0004] Since the lines are inevitably affected by human engineering activities such as coal mining, road construction, salt drying, excavation, etc., the ground surface often settles unevenly. The uneven settlement of the four foundations of the tower will cause the tower to tilt, the tower material to concentrate stress, deformation and bending, and even collapse.

[0005] First, add gaskets to the anchor bolts to raise the tower legs to ensure that there is no uneven deformation between the four tower legs. However, due to the limited length of the anchor bolts at the top of the tower leg pile, this method is more suitable for smaller uneven settlements. With slightly larger uneven deformations, this solution will not work.

[0006] Secondly, the foundation is excavated, the foundation is lifted with a hydraulic jack, the foundation is leveled with pads under the foundation and the foundation is pushed back into place with a jack, then the tower body is connected to the foundation, and finally the foundation is backfilled. This treatment method not only has high construction requirements and a large amount of tools, but also has a complex on-site layout, a large workload and labor intensity for construction workers. It is also difficult to find pads of suitable thickness under the foundation, and the uneven settlement between the tower legs is still difficult to eliminate. Summary of the invention

[0035] In order to better understand the present invention, the content of the present invention is further described below in conjunction with the accompanying drawings and examples.

[0036] The present invention provides a transmission tower clip-on anchor bolt, such as Figure 1As shown, it includes a hollow sleeve unit, a gasket unit and a snap-in bolt unit; the sleeve unit includes a hollow tubular sleeve 4 with openings at both ends, and a plurality of baffle assemblies are provided at different heights on the inner wall of the sleeve 4, and the sleeve unit is arranged on the foundation; the gasket unit is a plate-like structure, and the tower leg 13 of the transmission tower is arranged on the gasket unit, and the gasket unit is arranged on the upper surface of the sleeve unit; the snap-in bolt unit includes a long rod-shaped columnar stud 1 and a stinger assembly, and the stinger assembly is a plate-like structure, which is fixed to one end of the stud 1, and one end of the stud 1 having the stinger assembly passes through the gasket unit and enters the hollow part of the sleeve unit, and the stinger assembly is fixed to the baffle assembly of a suitable height in the sleeve 4 according to the height of the settlement of the sleeve unit on the foundation, and the other end of the stud 1 is fixed to the upper surface of the gasket unit. During installation, before the sleeve 4 is poured, the top of the sleeve 4 is sealed with a balloon to prevent pollutants such as concrete 7, rainwater, dust, etc. from falling into the sleeve 4 and damaging the inner wall of the sleeve 4 and the sleeve baffle assembly.

[0037] Furthermore, the outer surface of the sleeve 4 is made into an anti-slip shape, and the anti-slip measure can be welded steel bars and the like.

[0038] The invention discloses a clip-on anchor bolt for a power transmission tower. In areas with complex and changeable geological conditions, the defect of limited length of the anchor bolt of a tower foot plate 3 is overcome. The height of the stud 1 exposed outside the sleeve 4 is adjusted, and a pad 14 under the tower foot plate 3 is added to adjust the different heights of the tower leg 13 on the anchor bolt, thereby realizing the adjustment of the settlement height of the tower foundation in a smaller or larger range in an uneven settlement area, and solving the problem of uneven settlement of the tower foundation of the power transmission tower in an uneven settlement area.

[0039] In the present invention, if Figure 3 and Figure 4 As shown, each baffle assembly includes a pair of long strip baffles 6, both ends of which have arc edges that match the arc inner wall of the sleeve 4; and both ends of the arc edges of the baffles 6 are connected to the arc edges respectively.

[0040] The width of the baffle 6 is set according to the thorn assembly, that is, the setting of the width of the baffle 6 not only needs to reserve sufficient space for the thorn assembly to move up and down in the sleeve 4 to adjust the height, but also requires that after the thorn assembly is rotated 90°, the baffle 6 fixes the adjusted thorn assembly so that it can be firmly connected to the baffle 6 in the sleeve 4, and there is a gap between the baffle 6 and the inner wall of the sleeve 4 at the far end away from the axis of the sleeve 4, and the size of the gap is set according to actual needs.

[0041] Furthermore, the baffle 6 can be selected to be a 1 / 4 circular steel plate.

[0042] Furthermore, the distance between each pair of baffles 6 is determined according to the length of the sleeve 4, and it is further preferred that the spacing between adjacent baffle assemblies is 10 to 15 cm, to ensure that a single thorn assembly or multiple pairs of thorn assemblies can be fixedly connected according to the assembly connection position in the space outside the multiple groups of baffle assemblies provided at different heights on the inner wall of the sleeve 4.

[0043] In the present invention, the thorn assembly includes at least one pair of buckles 9 and barbs 8; when the buckles 9 and barbs 8 include multiple pairs, the thorn assembly is fixedly connected to multiple groups of baffle assemblies provided at different heights on the inner wall of the sleeve 4, and the connection and fixation are more firm.

[0044] Each pair of plate-shaped buckles 9 are welded in a straight line on both sides of the same height of the bottom cylindrical surface of the buckle bolt unit, ensuring that each pair of plate-shaped buckles 9 can clamp multiple groups of baffle assemblies provided at different heights on the inner wall of the sleeve 4 to the maximum extent.

[0045] Furthermore, when installing the pole tower, the stud 1 is placed along the direction without the baffle 6, and the stud 1 is lowered to the bottom layer of the sleeve 4. After the stud 1 is placed in the bottom layer, the stud 1 is rotated to buckle the barb 8 into the baffle slot 5.

[0046] The barb 8 is a spike structure, with the barb tip welded upward on the upper surface edge of the buckle 9 far away from the axis of the sleeve 4 and close to the inner wall of the sleeve 4, ensuring that multiple groups of baffle assemblies at different heights fixed to the inner wall of the sleeve 4 cannot move horizontally, thereby achieving a better stabilization effect.

[0047] In the present invention, the horizontal cross-sectional length of the buckle 9 is in the range of 3 / 8 to 1 / 2 of the diameter of the sleeve 4, the horizontal cross-sectional width is in the range of 1 / 4 to 3 / 4 of the diameter of the sleeve 4, and the longitudinal height is not more than 10 cm, to ensure that the buckle 9 can be pulled out and / or fixed to the baffle assembly in the space inside the sleeve 4.

[0048] Further, when installing the stud 1, the balloon at the top of the sleeve 4 is removed, and the top opening of the sleeve 4 is sealed with a gasket unit.

[0049] In the present invention, the buckle 9 is a long plate with a rectangular or right-angled trapezoidal longitudinal section, with the long right-angled side facing horizontally upward and the short right-angled side welded longitudinally on the stud 1, so as to maximize the contact area between the upper surface of the buckle assembly and the lower surface of the baffle assembly, increase the stability of the connection between the buckle assembly and the baffle assembly, and improve the fixing effect.

[0050] In the present invention, when there are at least two pairs of clips 9, the upper and lower adjacent clips 9 at the bottom of the stud 1 are parallel, and the spacing between the upper and lower adjacent and parallel clips 9 is consistent with the spacing between the baffles 6 at adjacent heights on the inner wall of the sleeve 4, ensuring that multiple pairs of clips 9 match the paired long strip baffles 6 on the sleeve 4, avoiding the situation where the clips 9 are not fastened to the baffles 6, and ensuring that the clips 9 on the clip assembly are all fastened to the baffle assembly on the inner wall of the sleeve 4.

[0051] Furthermore, in order to improve the stress of the stud 1, the buckles 9 on the stud 1 are welded in pairs from bottom to top. The data is determined according to actual needs, and 3 pairs can be continuously welded from the bottom of the sleeve 4.

[0052] In the present invention, the snap-on bolt unit also includes a nut 2. The end of the stud 1 exposed from the sleeve 4 is threaded and fixed to the upper surface of the gasket unit through the nut 2. The nut thread and the size of the nut are set according to actual needs.

[0053] Furthermore, the nut 2 may be a two-cornered bilateral shape or a hexagonal hexagonal shape.

[0054] In the present invention, the length of the stud 1 is greater than the length of the sleeve 4. Figure 2 As shown, in order to improve the force of the stud 1 and the sleeve 4, the length of the sleeve 4 and the stud 1 is increased as much as possible, the sleeve 4 is at least 1.5m long, and the exposed length of the stud 1 tower foundation reserves space for fixing the tower foot plate 3. The length of the stud 1 is ensured to be long enough, so that when the uneven stratum settles significantly, there is enough length to be pulled out and adjusted from the sleeve 4, thereby enhancing the adaptability to the settlement of the uneven stratum.

[0055] Furthermore, if the exposed stud 1 is long enough, just loosen the nut 2 and add a pad 14 under the tower leg plate; if the exposed stud 1 is not long enough, it is necessary to loosen the nut 2 of the pole tower foundation, press the stud 1 downward, make the barb 8 withdraw from the baffle slot 5, rotate the stud 1 ninety degrees, lift the stud 1 upward to a suitable height by the spacing of several baffles 6 as required, rotate it ninety degrees again, clip the stud 1 buckle 9 into the baffle 6, and further fix the barb 8 at the far end of the buckle 9 in the baffle slot 5.

[0056] In the present invention, if Figure 5 As shown, the padding unit includes a tower foot plate 3 and a pad 14. The tower foot plate 3 is above the pad 14. The side of the tower foot plate 3 fixes the tower leg 13 of the transmission tower. The thickness or number of the pad 14 is set according to the settlement amplitude. The pad 14 can be a rectangular steel plate with a hole of the same diameter as the stud 1 reserved, and pads 14 of different thicknesses are provided according to the settlement amplitude, and the number is determined according to actual needs.

[0057] Furthermore, when uneven settlement of the four tower legs is detected, the foundation with the largest settlement is found and the amount of height adjustment of the foundation is determined.

[0058] In the present invention, the pad 14 is in an M-shaped form, which ensures that there is no need to remove the nut 2. It is only necessary to loosen the nut 2, raise and correct the tower foundation, and pad the pad 14 with corresponding thickness and number according to the settlement amplitude.

[0059] Furthermore, the pad plate 14 may also be a steel plate as required.

[0060] In the present invention, if Figure 2 As shown, the baffle assembly also includes at least one reinforcing plate 12, which is a right-angled triangular plate-like structure, with its short right-angled side longitudinally fixed to the inner wall of the sleeve, and its long right-angled side vertically and fixed to the upper surface of the baffle 6; the baffle 6 and the two reinforcing plates 12 form a baffle groove body 5 at the inner wall of the sleeve 4 in close contact, and the baffle groove body 5 is located in the central part of the gap of the baffle 6; when the buckle assembly clamps the baffle assembly, the upward barb tip of the barb 8 is fixed in the baffle groove body 5.

[0061] Furthermore, the length of the reinforcing plate 12 is about 3 / 8 of the diameter of the sleeve 4, and can be a steel plate. It is further preferred that there are two pairs of steel plates on each baffle.

[0062] The reinforcing plate 12 on the baffle assembly enhances the stability of the baffle assembly on the inner wall of the sleeve 4 and enhances the fixing effect of the baffle assembly.

[0063] Furthermore, the flat steel plate can be bent into two semicircles, and after the baffle plate 6 and the reinforcing plate 12 are welded, they are welded into a cylindrical shape.

[0064] In the present invention, the sleeve unit also includes a sleeve base assembly, and the sleeve base assembly includes a bottom plate 11. The bottom plate 11 is a rectangular long plate with a long side that is 3 to 5 times the diameter of the sleeve. It is horizontally placed at the bottom of the sleeve unit, and the upper surface is welded to seal the bottom end of the sleeve 4 to form a T-shaped structure with the sleeve 4. The bottom plate 11 is welded to seal the bottom end of the sleeve 4 to ensure that the space inside the sleeve 4 is not filled due to uneven stratum settlement, thereby affecting the extraction and movement of the snap assembly in the sleeve 4 and the fixing of the baffle assembly.

[0065] Furthermore, the bottom cover plate 11 may be a steel plate.

[0066] In the present invention, the T-shaped structure connection part is welded with a wing plate 10, and more preferably, the wing plate 10 can be a steel bar or a steel plate. The wing plate 10 further enhances the stability and firmness of the connection between the bottom plate 11 and the sleeve 4.

[0067] In the present invention, the anchor bolt also includes a barrel-shaped conical structure cast with concrete 7, the barrel-shaped conical structure is arranged on the foundation, and the footboard 3 is fixed on the top, the sleeve 4 is cast in the concrete 7, and the top of the sleeve 4 is flush with the upper surface of the barrel-shaped conical structure. The barrel-shaped conical structure cast with concrete 7 protects the sleeve unit from being affected by the external environment and enhances the stability and firmness of the sleeve unit.

[0068] Furthermore, the pole tower foundation formed by pouring concrete 7 is a column foundation structure with a bottom diameter smaller than an upper diameter.

[0069] Compared with the prior art, the present invention also has the following beneficial effects:

[0070] The present invention avoids the complex construction means of excavating the foundation and then backfilling the foundation required by the traditional method, and solves the problems of high construction requirements, large amount of tools and equipment, complex on-site layout, large workload and labor intensity of construction personnel.

[0071] The invention solves the problem that it is difficult to find a cushion block of suitable thickness under the foundation, resulting in uneven settlement thickness between tower legs, which is still difficult to eliminate.

[0072] The device has a simple structure, low cost, convenient construction and a wide range of applications. When constructing a pole tower in an area where uneven settlement may occur, the scheme of the present invention is adopted to perform adjustments when uneven settlement occurs.
