Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of transmission lines in power systems, and more specifically, it is an assembled tower foundation for power lines. The present invention also relates to an assembly method for such an assembled tower foundation for power lines. Background Art
[0002] The tower is one of the basic equipment in overhead power transmission and distribution lines. It is a support for overhead power transmission and distribution lines to support transmission wires and is the main support structure of overhead power transmission and distribution lines; the tower concrete pile foundation is a key component for supporting various tower facilities (such as power towers, communication towers, etc.); the role of the tower pile foundation is to effectively transfer the loads (such as wind loads, gravity loads, impact loads, etc.) borne by the tower to the concrete pile foundation to ensure the stability and safety of the tower structure; currently, the common power line towers in China can be divided into three types according to the materials used: wooden poles, cement poles, and metal poles. Cement poles have the advantages of long service life and small maintenance workload, and are widely used. The most commonly used cement poles are tapered poles.
[0003] Long-term operation and maintenance experience shows that the tower foundations of current overhead power transmission and distribution lines are mostly deep-buried and cement-cast types. These two types of foundations require a deep foundation during on-site construction, so the operation difficulty is high, the workload is large, the construction time is long, and large machinery is mostly required for operation, increasing the construction cost, increasing the occupation of land resources, and causing great damage to the environment; under the influence of various factors such as typhoons, geological settlement, debris flows, floods, and vehicle impacts in complex natural environments, cement poles are prone to toppling, and some foundations are soft or not tamped, resulting in the sinking or tilting of cement poles; in addition, cement poles exposed to harsh environments for a long time may develop cracks or corrosion, and the stability of the cement medium is greatly reduced. If the design of the cement tower concrete pile foundation is unreasonable, with insufficient burial depth or insufficient structural strength, it is easy to cause toppling; in addition, if the installation of the cement tower pile foundation is not standardized, such as the concrete pile foundation not being buried according to the standard or not being firmly fixed, there is also a risk of toppling.

[0017] To achieve the above second object, the technical solution of the present invention is: an assembly method for an assembled tower foundation of a power line, characterized by comprising the following steps: Step 1: Insert the square positioning rod into the square groove. During the insertion process of the square positioning rod, through the clamping function of the clamping mechanism, a plurality of pin columns are respectively clamped into a plurality of pin slots, thereby realizing the connection operation between the square positioning rod and the base; Step 2: Place the positioning seat into the dug foundation, and insert the two circular fixing rods at the bottom of the positioning seat into the foundation. Lift the base by a hoisting device, align the four square positioning rods with the four positioning holes respectively, and then move the base and the four square positioning rods downward. When the square positioning rod moves downward, under the action of the sliding mechanism, drive the two rectangular sliders to move synchronously in opposite directions, thereby enhancing the fixing effect of the positioning seat under the action of the reinforcement mechanism; Step 3: When the bidirectional screw guide sleeve rotates, drive the lead screw to rotate through the linkage unit, drive a plurality of lifting columns to move downward synchronously through the thread action, extrude a plurality of plug-in blocks, so that a plurality of plug-in blocks move synchronously in a direction away from the axis and insert into the soil, further improving the fixing and limiting function of the positioning seat; Step 4: When the rectangular slider moves horizontally, the top of the U-shaped limiting block can be made to fit with the bottom of the L-shaped clamping plate through the action of the extrusion limiting mechanism, realizing the fixing and limiting function of the positioning seat and the base, preventing the base from moving vertically. Then, grout is poured into the L-shaped groove through the grouting hole. Since the L-shaped groove, the rectangular cavity, and the transmission cavity are all connected, the slurry can be filled into each position. When the slurry solidifies, the connection and fixing effect of the positioning seat and the base is improved.
[0018] Compared with the prior art, the present invention has the following advantages: 1) When the square positioning rod moves downward in the present invention, it drives the lifting rack to move downward synchronously and engage with the rotating gear, causing the two bidirectional screw guide sleeves to rotate synchronously. Through the thread action, drive the two screws and the two rectangular sliders to move synchronously in opposite directions. Drive the two transverse metal insertion rods to move synchronously through the rectangular slider and insert into the inner wall of one side of the foundation. Moreover, during the movement of the rectangular slider, under the action of the two second connecting rods, drive the two longitudinal metal insertion rods to move in opposite directions and insert into the inner walls of the other two sides of the foundation, thereby enhancing the fixing effect of the positioning seat.
[0019] 2) By rotating the bidirectional screw guide sleeve in the present invention, the lead screw can be driven to realize the rotation function. When the lead screw rotates, under the limiting action of the limiting shaft, the three lifting columns move downward synchronously, extrude a plurality of plug-in blocks through the annular extrusion groove, so that a plurality of plug-in blocks move synchronously in a direction away from the axis and insert into the soil, further improving the fixing and limiting function of the positioning seat and preventing it from displacing in any direction.
[0020] 3) The present invention drives the trapezoidal extrusion block to move synchronously through the L-shaped clamping plate, thereby extruding the inner wall of the bottom of the U-shaped limiting block, making the top of the U-shaped limiting block fit with the bottom of the L-shaped clamping plate. Then, grout is poured into the L-shaped groove through one of the grouting holes, and the vibration device is placed into the other grouting hole to vibrate the internal grout, eliminating the internal air bubbles. Since the L-shaped groove, the multiple rectangular cavities, and the transmission cavity are all connected and communicated, the grout can be filled to each position. When the grout solidifies, the connection and fixing effect between the positioning seat and the base is improved, and each component is limited, greatly improving the overall stability of the foundation.

[0043] Two grouting holes 260 are formed in the top inner wall of the base 200. The two grouting holes 260 are respectively communicated with the two L-shaped grooves 250.
[0044] An assembly method for an assembled tower foundation of a power line is characterized by comprising the following steps: Step 1: Insert the square positioning rod 300 into the square groove 220. During the insertion process of the square positioning rod 300, the extrusion column 410 is extruded. When the extrusion column 410 slides into the rectangular cavity 230, through the connection of the four first connecting rods 540, four of the transmission racks 530 can be driven to move synchronously away from the axis direction. Through the meshing of the four transmission gears 550, the other four transmission racks 530, four connecting sliders 560, and four square plates 420 can be driven to move synchronously towards the axis direction. During the movement of the square plate 420, the sleeve 421 and the pin 422 can be driven to move synchronously. When the pin 422 contacts the side of the square positioning rod 300, the pin 422 stops moving due to the extrusion effect. At this time, the sleeve 421 continues to move and extrudes the compression spring 423. When the square positioning rod 300 moves to the top inner wall of the square groove 220, the pin 422 corresponds to the pin groove position. At this time, the pin 422 realizes the reset function through the elastic action of the compression spring 423, and the connection operation between the square positioning rod 300 and the base 200 is realized; Step 2: Place the positioning seat 100 into the dug foundation, so that the two circular fixing rods 130 at the bottom of the positioning seat 100 are inserted into the foundation. Lift the base 200 by a hoisting device, align the four square positioning rods 300 with the four positioning holes 110 respectively, and then move the base 200 and the four square positioning rods 300 downward. When the square positioning rod 300 moves downward, it drives the lifting rack 310 to move downward synchronously and engage with the rotating gear 611. When multiple rotating gears 611 rotate, they drive the two bidirectional screw bushings 610 to rotate synchronously, so that the two screws 620 in the same bidirectional screw bushing 610 move synchronously in the opposite direction, and finally the two rectangular sliders 610 move away from each other synchronously. The two transverse metal insertion rods 710 are driven to move synchronously by the rectangular sliders 610 and inserted into the inner wall of one side of the foundation. During the movement of the rectangular sliders 610, under the action of the two second connecting rods 730, the two longitudinal metal insertion rods 720 can be driven to move away from each other and inserted into the inner walls of the other two sides of the foundation, thereby enhancing the fixing effect of the positioning seat 100; Step 3: When the bidirectional screw guide sleeve 610 rotates, through the meshing of the two sprockets 1200 and the chain 100, the rotating shaft 1100 can be driven to achieve the synchronous rotation function. When the rotating shaft 1100 rotates, through the meshing of the worm 1400 and the worm gear 1500, the lead screw 910 is driven to rotate. Since the rotational speeds of the worm 1400 and the worm gear 1500 are different, the rotational speed of the rotating shaft 2200 is higher than that of the lead screw 910. When the lead screw 910 rotates, under the limiting action of the limiting shaft 132, the three lifting columns 750 move downward synchronously. Through the annular extrusion groove, the plurality of insertion blocks 740 are extruded, so that the plurality of insertion blocks 740 move synchronously away from the axis direction and are inserted into the soil, further improving the fixed limiting function of the positioning seat 100 and preventing it from displacing in any direction. Step 4: When the rectangular slider 610 moves horizontally, it can drive the L-shaped clamping plate 810 to move synchronously. When the L-shaped clamping plate 810 moves, it drives the trapezoidal extrusion block 820 to move synchronously. Through the movement of the trapezoidal extrusion block 820, the bottom inner wall of the U-shaped limiting block 840 is extruded, so that it moves upward under the guiding action of the two guiding shafts 830 until the top of the U-shaped limiting block 840 fits against the bottom of the L-shaped clamping plate 810. Then, grout is poured into the L-shaped groove 250 through one of the grouting holes 260. The vibration device is placed into the other grouting hole 260 to vibrate the internal slurry to eliminate internal air bubbles. Since the L-shaped groove 250, the plurality of rectangular cavities 230, and the transmission cavity 120 are all connected and communicated, the slurry can be filled to each position. When the slurry solidifies, the connection and fixing effect of the positioning seat 100 and the base 200 is improved, and each component is limited, greatly improving the overall stability of the foundation.
