Description

Technical Field

[0001] This utility model relates to the field of power transmission tower technology, specifically a movable earthquake-resistant power transmission tower. Background Technology

[0002] Electric power towers are trapezoidal or triangular structures, typically 25-40 meters high, and are made of steel frames. High-voltage power towers are an important means of power transmission in my country.

[0003] A seismic-resistant transmission tower, such as one disclosed in CN210002993U, includes: a seismic-resistant base and a tower body installed on the seismic-resistant base; the seismic-resistant base includes: a first cement base including a first groove; a second cement base housed in the first groove; a plurality of spaced I-shaped support columns, each end of which is embedded in the first cement base and the second cement base respectively; an asphalt damping layer filling the space between the first cement base and the second cement base; a first support plate embedded in the second cement base; a second support plate disposed on the second cement base, and the tower body disposed on the second support plate; a plurality of first support columns supporting the space between the first support plate and the second support plate; and a compression spring sleeved on the first support columns and elastically supported between the first support plate and the second support plate.

[0004] However, based on the working principle proposed in the aforementioned patent, the applicant believes that although the aforementioned device can enhance seismic resistance to a certain extent, in actual use, the aforementioned device makes the transmission tower completely fixed in one place, making it difficult to move it, which is somewhat inconvenient to use.

[0005] Therefore, a movable seismic-resistant transmission tower is proposed to address the above problems. Utility Model Content

[0006] The technical problem to be solved by this utility model is that the existing technology has the disadvantage of making it difficult to move the transmission tower. Therefore, we propose a movable earthquake-resistant transmission tower.

[0007] The technical solution adopted by this utility model to solve its technical problem is: a movable earthquake-resistant transmission tower, including a cross-shaped connecting plate; a ring block is fixedly installed on the inner side of the cross-shaped connecting plate, a sliding ball is movably installed on the lower surface of the ring block, a bottom frame plate is fixedly connected to the outer side of the cross-shaped connecting plate, connecting screw holes are opened on the surface of the bottom frame plate, an outer plate is installed on the outer side of the bottom frame plate by fixing bolts, an adjustment hole is opened on the surface of the outer plate, a lower connecting plate is fixedly installed at the bottom of the outer plate, and a fixing hole is opened on the surface of the lower connecting plate.

[0008] Preferably, lower sleeve blocks are fixedly installed at each of the four corners of the bottom frame plate, and shock absorbers are fixedly installed on the inner side of the lower sleeve blocks.

[0009] Preferably, the top of the shock absorber is fixedly connected to an upper sleeve block, and a cover block is fixedly installed on the top of the upper sleeve block.

[0010] Preferably, a ring plate is fixedly installed on the lower surface of the upper sleeve block, and a panel is fixedly installed on the upper surface of the lower sleeve block.

[0011] Preferably, an angle steel column leg is movably installed on the inner side of the cover block, and through holes are provided on both the angle steel column leg and the outer side of the cover block.

[0012] Preferably, a threaded rod is movably installed on the inner side of the perforation, and a limit nut is installed on the threaded surface of the threaded rod. The angle steel column leg is fixedly installed around the tower body.

[0013] The beneficial effects of this utility model are:

[0014] 1. This utility model, through the setting of the cross connecting plate, facilitates the enhancement of the installation strength of the ring block. The setting of the ring block also facilitates the provision of an installation site for the sliding ball. Under normal conditions, the sliding ball is in direct contact with the ground, which can greatly reduce the friction between the entire transmission tower and the ground, making it easier to move on flat ground. When the transmission tower needs to be fixed as a whole, the height of the connection between the outer plate and the bottom frame plate can be adjusted so that the lower plate can make direct contact with the ground. Then, the entire transmission tower can be fixed in a certain place by driving expansion bolts into the fixing holes and the ground. By linking the sliding ball and the lower plate, the overall device is easier to assemble, disassemble and adjust its position.

[0015] 2. This utility model, through the setting of the shock absorber damper, allows the impact that the transmission tower may be subjected to to be transmitted to the surface of the spring, thereby buffering it and achieving the ability to resist earthquakes. The shock absorber damper can also eliminate the swaying that may occur when the spring is under force. Through the setting of the cover block, the surface of which has grooves for receiving the angle steel column legs, the limiting ability of the angle steel column legs can be greatly enhanced. Through the setting of the ring plate and the inlay plate, the two are nested together, which can further reduce the swaying that may occur when the shock absorber damper is under force. Through the setting of the perforation, the connection between the angle steel column legs and the cover block can be strengthened, thereby enhancing the overall stability and strength of the transmission tower. Through the setting of the through bolt and the limiting nut, it is easy to fix and limit the angle steel column legs and the cover block. Attached Figure Description

[0025] This application discloses a movable seismic-resistant transmission tower. (Refer to...) Figure 3 and Figure 4A movable seismic-resistant transmission tower includes a cross-shaped connecting plate 1; a ring block 2 is fixedly installed on the inner side of the cross-shaped connecting plate 1, and a sliding ball 3 is movably installed on the lower surface of the ring block 2; a bottom frame plate 4 is fixedly connected to the outer side of the cross-shaped connecting plate 1; connecting screw holes 5 are opened on the surface of the bottom frame plate 4; an outer plate 7 is installed on the outer side of the bottom frame plate 4 by fixing bolts 6; an adjustment hole 8 is opened on the surface of the outer plate 7; a lower connecting plate 9 is fixedly installed at the bottom of the outer plate 7; and fixing holes 10 are opened on the surface of the lower connecting plate 9. The cross-shaped connecting plate 1 facilitates the installation strength of the ring block 2, and the ring block 2 facilitates the installation site for the sliding ball 3. Under normal conditions, the sliding ball 3 is in direct contact with the ground, which can greatly reduce the friction between the entire transmission tower and the ground, making it easier to move on flat ground. When the entire transmission tower needs to be fixed, the height of the connection between the outer plate 7 and the bottom frame plate 4 can be adjusted so that the lower connecting plate 9 is in direct contact with the ground, and then the entire transmission tower is fixed in a certain place by driving expansion bolts into the fixing holes 10 and the ground.

[0026] Reference Figure 2 and Figure 5 The bottom frame plate 4 has a lower sleeve block 11 fixedly installed at each of the four corners, and a shock absorber 12 is fixedly installed on the inner side of the lower sleeve block 11. The shock absorber 12 can transmit the impact that the transmission tower may be subjected to to the surface of the spring, thereby buffering it and achieving the ability to resist earthquakes. The shock absorber 12 can also prevent the spring from shaking under force.

[0027] Reference Figure 2 and Figure 5 The top of the shock absorber 12 is fixedly connected to an upper sleeve block 13, and a cover block 14 is fixedly installed on the top of the upper sleeve block 13. The cover block 14 has a groove on its surface for receiving the angle steel column leg 17, which can greatly enhance the limiting ability of the angle steel column leg 17.

[0028] Reference Figure 2 and Figure 5 A ring plate 15 is fixedly installed on the lower surface of the upper sleeve block 13, and a panel 16 is fixedly installed on the upper surface of the lower sleeve block 11. The ring plate 15 and the panel 16 are nested together, which can further reduce the shaking that may occur when the shock absorber 12 is subjected to force.

[0029] Reference Figure 1 and Figure 2 Angle steel column legs 17 are movably installed on the inner side of the cover block 14, and through holes are provided on the outer side of both the angle steel column legs 17 and the cover block 14; the through holes can enhance the connection between the angle steel column legs 17 and the cover block 14, thereby enhancing the overall stability and strength of the transmission tower.

[0030] Reference Figure 1 and Figure 2A through-bolt 18 is movably installed on the inner side of the perforation, and a limit nut 19 is installed on the surface thread of the through-bolt 18. Angle steel column legs 17 are fixedly installed around the tower body 20. The through-bolt 18 and the limit nut 19 facilitate the fixing and limiting of the angle steel column legs 17 and the cover block 14.

[0031] Working principle: Under normal conditions, the sliding ball 3 is in direct contact with the ground, which greatly reduces the friction between the entire transmission tower and the ground, making it easier to move on flat ground. When the transmission tower needs to be fixed as a whole, the height of the connection between the outer plate 7 and the bottom frame plate 4 can be adjusted so that the lower plate 9 can make direct contact with the ground. Then, the entire transmission tower can be fixed in a certain place by driving expansion bolts into the fixing holes 10 and the ground. By linking the sliding ball 3 and the lower plate 9, the entire device is easier to assemble, disassemble and adjust.
