Description

Technical Field

[0001] This utility model relates to a spliced ​​steel pipe tower, belonging to the technical field of steel pipe towers. Background Technology

[0002] Steel pipe tower: A lattice tower composed of steel pipes as the main component and steel pipes or structural steel as other components. It is a support structure for overhead transmission lines to support conductors and lightning protection wires, so that the conductors meet the distance requirements to the ground and ground objects, and can withstand the loads of the conductors, lightning protection wires and their own loads as well as external loads.

[0003] The existing patent number CN217735048U describes a spliced ​​stable steel pipe tower. First, a collar is fitted onto the second steel pipe, and bolts are used to fix the collar to the second steel pipe. Then, one end of the first steel pipe is aligned with the collar and inserted, and bolts are used to fix the ring plate to the first steel pipe. This facilitates the installation and disassembly of the first and second steel pipes. After the first and second steel pipes are spliced, workers use external lifting equipment to lift the second steel pipe, inserting its bottom end into the slot of the base. Then, workers insert it into the mounting groove of the base. The first part involves pouring concrete to firmly fix the second steel pipe and the base together, improving the stability of the entire device. However, the steel pipe tower used in this device also needs to be bolted from the outside. When multiple steel pipes are stacked together, it is time-consuming and labor-intensive, affecting the ease of disassembly and assembly of the steel pipe tower. In addition, although the method of fixing the bottom by pouring concrete can ensure the installation stability of the steel pipe tower, it is time-consuming and labor-intensive when it needs to be replaced or removed, and the base cannot be reused, affecting the ease of replacement and disassembly of the old steel pipe tower. Utility Model Content

[0004] The purpose of this invention is to provide a modular steel pipe tower to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A modular steel pipe tower includes a bottom pipe, a middle pipe, and a top pipe. The upper end of the bottom pipe is provided with a middle pipe, and the upper end of the middle pipe is provided with a top pipe. The lower ends of the middle pipe and the top pipe are fixedly connected with limit rings. The limit rings are slidably connected to the bottom pipe and the middle pipe, respectively. The upper inner sides of the bottom pipe and the middle pipe are fixedly connected with fixed support plates. The inner and outer sides of the fixed support plates are slidably connected with limit plates. The limit plates are slidably connected to the bottom pipe, the middle pipe, and the limit rings, respectively. The lower end of the bottom pipe is provided with a base. An embedded block is fixedly connected at the middle position of the lower end of the bottom pipe. The embedded block is slidably connected to the base. The inner side of the embedded block is slidably connected with a locking block.

[0007] Furthermore, a rotating screw is rotatably connected to the upper end of the jacking pipe, a turntable is fixedly connected to the upper end of the rotating screw, a pressing sleeve is spirally connected to the lower side of the rotating screw, a cross-shaped locking block is fixedly connected to the lower end of the pressing sleeve, a lifting transmission pipe is slidably connected to the outer side of the cross-shaped locking block, a transmission rod is rotatably connected to the outer side of the lifting transmission pipe, and the transmission rod is rotatably connected to the limiting insert plate.

[0008] Furthermore, a fixed T-shaped rod is fixedly connected at the middle position of the upper end of the fixed support plate, and the fixed T-shaped rod is slidably connected to the lifting transmission tube. A spring is provided on the upper side of the inside of the lifting transmission tube.

[0009] Furthermore, a connecting rod is slidably connected to the inside of the fixed support plate near the middle position.

[0010] Furthermore, the base has threaded shafts rotatably connected in all directions (front, back, left, right) inside. A movable plate is helically connected to the outer side of the threaded shaft. The movable plate is slidably connected to the base. The movable plate is fixedly connected to a locking block. A control motor is provided at the front end of the threaded shaft. The control motor is fixedly connected to the base. A bevel gear set is fixedly connected to the inner end of the threaded shaft.

[0011] Furthermore, the front end of the base is provided with a protective sealing plate, the position of which corresponds to the position of the control motor.

[0012] Furthermore, there are two of each of the cross-shaped locking block and the lifting transmission tube. The lower cross-shaped locking block is fixedly connected to the connecting slide rod, and the upper lifting transmission tube is fixedly connected to the connecting slide rod.

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

[0014] This invention utilizes a limiting insert ring to allow the upper middle layer tube and top tube to be inserted sequentially onto the upper ends of the bottom tube and middle layer tube. Rotation of the turntable causes the rotating screw to rotate, and when the top tube is inserted into the upper end of the middle layer tube, the cross-shaped locking block inserts into the inner side of the lifting transmission tube. This allows the top pressure sleeve to move the cross-shaped locking block and the lifting transmission tube downwards. Meanwhile, the cross-shaped locking block at the lower end of the connecting slide rod presses the lifting transmission tube inside the bottom tube downwards, causing the transmission rod to push the limiting insert plate outwards. This ensures that the connection points between the bottom tube and middle layer tube, and between the middle layer tube and top tube, are simultaneously subject to multiple limiting mechanisms. The limiting and locking mechanism of the insert plate enables rapid splicing and fixing of multiple layers of steel pipe towers. This utility model utilizes the function of the embedded block to limit the bottom pipe in the horizontal direction. By opening the protective sealing plate, the control motor can be turned on, thereby allowing the threaded shaft at the front end to rotate. Through the action of the set bevel gear, multiple threaded shafts can be driven to rotate simultaneously, which in turn allows the movable plate to drive the locking block to be inserted into the embedded block, thereby achieving longitudinal limiting of the bottom pipe. Furthermore, the embedded block can be quickly removed when it is necessary to disassemble and replace the old steel pipe tower, improving the convenience of replacing and disassembling the old steel pipe tower.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please refer to Example 1 Figures 1-4 This utility model provides a technical solution:

[0023] A modular steel pipe tower includes a bottom pipe 1, a middle pipe 2, and a top pipe 3. The middle pipe 2 is located above the bottom pipe 1, and the top pipe 3 is located above the middle pipe 2. Limiting rings 4 are fixedly connected to the lower ends of both the middle pipe 2 and the top pipe 3. The limiting rings 4 are slidably connected to the bottom pipe 1 and the middle pipe 2, respectively. Fixed support plates 5 are fixedly connected to the upper inner sides of both the bottom pipe 1 and the middle pipe 2. Limiting plates 6 are slidably connected to the inner and outer sides of the fixed support plates 5. The limiting plates 6 are slidably connected to the bottom pipe 1, the middle pipe 2, and the limiting rings 4, respectively. A rotating mechanism is rotatably connected to the upper inner side of the top pipe 3. A rotating screw 10 is fixedly connected to a turntable 11 at its upper end. A pressure sleeve 12 is spirally connected to the lower part of the rotating screw 10. A cross-shaped locking block 13 is fixedly connected to the lower end of the pressure sleeve 12. A lifting transmission pipe 14 is slidably connected to the outer side of the cross-shaped locking block 13. A transmission rod 15 is rotatably connected to the outer side of the lifting transmission pipe 14. The transmission rod 15 is rotatably connected to the limiting insert plate 6. A fixed T-shaped rod 16 is fixedly connected to the middle position of the upper end of the fixed support plate 5. The fixed T-shaped rod 16 is slidably connected to the lifting transmission pipe 14. A spring 17 is provided on the upper side of the interior. A connecting slide rod 18 is slidably connected to the interior of the fixed support plate 5 near the middle position. There are two cross-shaped locking blocks 13 and two lifting transmission tubes 14. The cross-shaped locking blocks 13 at the lower end are fixedly connected to the connecting slide rod 18, and the lifting transmission tubes 14 at the upper end are fixedly connected to the connecting slide rod 18. By setting the limiting insertion ring 4, the upper middle layer tube 2 and the top tube 3 can be inserted into the upper end of the bottom tube 1 and the middle layer tube 2 in sequence. By rotating the turntable 11, the rotating screw 10 can be rotated, and the top tube 3 is inserted into the middle layer tube 2. When the middle layer pipe 2 is at the top, the cross-shaped locking block 13 can be inserted into the inside of the lifting transmission pipe 14, which allows the top pressure sleeve 12 to drive the cross-shaped locking block 13 and the lifting transmission pipe 14 to move downward. The cross-shaped locking block 13 at the lower end of the connecting slide rod 18 will press the lifting transmission pipe 14 inside the bottom pipe 1 downward, which allows the transmission rod 15 to push the limiting plate 6 outward, so that the connection between the bottom pipe 1 and the middle layer pipe 2, as well as the connection between the middle layer pipe 2 and the top pipe 3, can be simultaneously limited and locked by multiple limiting plates 6, enabling the multi-layer steel pipe tower to be quickly spliced ​​and fixed.

[0024] Please refer to Example 2 Figure 1 and Figure 4 The difference between this embodiment and Embodiment 1 is as follows: A base 7 is provided at the lower end of the bottom tube 1. An embedded block 8 is fixedly connected to the middle position of the lower end of the bottom tube 1. The embedded block 8 is slidably connected to the base 7. A locking block 9 is slidably connected to the inner side of the embedded block 8. A threaded shaft 19 is rotatably connected to the inside of the base 7 in all directions (front, back, left, and right). A movable plate 20 is helically connected to the outer side of the threaded shaft 19. The movable plate 20 is slidably connected to the base 7. The movable plate 20 is fixedly connected to the locking block 9. A control motor 21 is provided at the front end of the threaded shaft 19. The control motor 21 is fixedly connected to the base 7. A bevel gear set 22 is fixedly connected to the inner end of the threaded shaft 19. The front end of 7 is provided with a protective sealing plate 23, the position of which corresponds to the position of the control motor 21. The bottom tube 1 is horizontally limited by the function of the embedded block 8. The control motor 21 can be turned on by opening the protective sealing plate 23, which in turn allows the threaded shaft 19 at the front end to rotate. The set bevel gear group 22 can drive multiple threaded shafts 19 to rotate simultaneously, which allows the movable plate 20 to drive the locking block 9 to be inserted into the embedded block 8, thereby achieving longitudinal limitation of the bottom tube 1. The embedded block 8 can be quickly removed when the scrap steel pipe tower needs to be disassembled and replaced, improving the convenience of replacing and disassembling the scrap steel pipe tower.

[0025] The working principle of this utility model is as follows: When in use, the limiting ring 4 allows the upper middle tube 2 and top tube 3 to be inserted sequentially into the upper ends of the bottom tube 1 and middle tube 2. Rotation of the turntable 11 causes the rotating screw 10 to rotate. When the top tube 3 is inserted into the upper end of the middle tube 2, the cross-shaped locking block 13 inserts into the inner side of the lifting transmission tube 14. This allows the top-pressing sleeve 12 to drive the cross-shaped locking block 13 and the lifting transmission tube 14 downwards. The cross-shaped locking block 13, located at the lower end of the connecting slide rod 18, presses the lifting transmission tube 14 inside the bottom tube 1 downwards, causing the transmission rod 15 to push the limiting plate 6 outwards, thus allowing the bottom tube 1 and middle tube 2, as well as the middle tube 2 and top tube 3, to move downwards. The connection of pipe 3 can be simultaneously locked by multiple limiting plates 6, enabling rapid splicing and fixing of multiple layers of steel pipe tower. The embedded block 8 enables the bottom pipe 1 to be horizontally limited. The opening of the protective sealing plate 23 enables the control motor 21 to be turned on, thereby allowing the threaded shaft 19 at the front end to rotate. The bevel gear set 22 drives multiple threaded shafts 19 to rotate simultaneously, thereby enabling the movable plate 20 to drive the locking block 9 to be inserted into the embedded block 8, achieving longitudinal limitation of the bottom pipe 1. The embedded block 8 can be quickly removed when the old steel pipe tower needs to be disassembled and replaced, improving the convenience of replacing and disassembling the old steel pipe tower.
