Description

Technical Field

[0001] The invention belongs to the technical field of communication iron towers, and in particular relates to a bottom fixing device of a communication iron tower. Background Art

[0002] A communication tower is a tall steel structure or other material structure, mainly used to support communication antennas, microwave equipment, wireless communication base stations and other communication equipment to achieve signal transmission and reception, and ensure the coverage and communication quality of the communication network. A single-tube tower is a communication tower with the appearance of a single steel pipe, usually with a larger diameter at the bottom and gradually narrowing upwards. The single-tube tower has a simple structure, beautiful shape, and small footprint. It is widely used in areas with high requirements for urban landscape or places with limited space.

[0003] The bottom of the communication tower is usually fixed by pre-embedded anchor bolts in the concrete foundation. The connecting flange at the bottom of the tower is inserted into the anchor bolts through the bolt holes, and then tightened with nuts to tightly connect the tower to the foundation and transfer the load of the tower to the foundation and the ground. However, during the use of the communication tower, it will be affected by various vibration factors. For example, the tower will swing under the action of wind load, and the communication equipment on the tower will also vibrate when it is running. These vibrations are transmitted to the anchor bolts, causing the bolts to be in an alternating stress state for a long time. Over time, the preload between the nut and the bolt will gradually decrease, causing the bolts to loosen. Loose bolts will reduce the stability of the tower and increase safety risks. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a communication tower bottom fixing device.

[0005] The technical solution adopted to solve the above technical problems is: a bottom fixing device of a communication tower, including a tower body, a mounting base fixedly connected to the lower end of the tower body, a mounting seat fixedly installed at the lower end of the mounting base, the mounting base, the mounting seat and the tower body are integrated, a fixing box is arranged at the lower end of the mounting seat, a fixing ring seat is fixedly connected in the fixing box, a plurality of plug holes are evenly circumferentially opened on the fixing box, quick-release fixing nuts are correspondingly arranged in the plug holes, an elastic connecting rod is fixedly connected to the lower end of the quick-release fixing nut, and a positioning clamp is arranged at one end of the elastic connecting rod; a plurality of quick-release fixing nuts are respectively provided with splicing auxiliary structures on one side, a driving mechanism is fixedly installed in the fixing box, a quick-release fixing mechanism is respectively provided on the other side of the plurality of quick-release fixing nuts, and an automatic alarm mechanism is fixedly installed on the outer side of the fixing box.

It is especially suitable for scenarios where communication networks need to be established quickly.

[0007] Furthermore, the splicing auxiliary structure includes an extended screw rod slidably connected to the fixed box, the upper end of the extended screw rod is threadedly connected to a supporting nut, the lower end of the extended screw rod is fixedly installed with a limit block, the extended screw rod is provided with a shift fork, one end of the shift fork is fixedly connected to the extended rod, the end of the extended rod rod away from the shift fork is fixedly connected to a moving block, the moving block is fixedly installed with a limit shaft, a connecting seat is fixedly installed on one side of the shift fork, a rotating support is installed above the connecting seat, first limit sliding grooves are symmetrically opened on both sides of the rotating support, a rolling wheel is provided in the rotating support, a connecting shaft is rotatably connected to the center position of the rolling wheel, a limiting cap is fixedly connected to the connecting shaft, and the connecting shaft is slidably connected to the first limit sliding groove.

[0008] Through the above technical scheme, the limit between the limit shaft and the second limit slide groove causes the moving block to rotate upward, and then the shift fork to rotate downward. By using the lever principle to pull the limit block and the support nut, the positioning clamp at the other end of the elastic connecting rod at the corresponding position can pass through the mounting seat and the fixed box. The rolling wheel serves as a lever fulcrum, which can provide support for the shift fork and the extension rod, and it can also slide in the first limit slide groove. The design of the rotating support can provide a larger support surface for the lever structure to reduce pressure damage to the fixed box.

[0009] Furthermore, the driving mechanism includes a connecting plate fixedly installed on the inner wall of the fixed box, a plurality of connecting rods are fixedly arranged on the circumference of the connecting plate, one end of the connecting rod is fixedly connected to a support frame, second limiting slide grooves are symmetrically provided on both sides of the support frame, a first positioning seat is slidably installed between the support frames, a mounting rail is fixedly connected to the first positioning seat, the moving block is slidably connected to the mounting rail, and the second limiting slide groove is slidably connected to the limiting shaft.

[0010] Through the above technical solution, during use, the limiting action between the second limiting slide groove and the limiting shaft enables the moving block to rotate upward, and at the same time can provide a support point for the moving block, thereby enhancing the stability of the entire device.

[0011] Furthermore, a cylinder is fixedly connected in the fixed box, a mounting plate is fixedly connected to the output end of the cylinder, the mounting plate is fixedly connected to the fixed chassis, a fixing column is installed on the fixed chassis, and the fixing column is fixedly installed to the first positioning seat.

[0012] Through the above technical solution, the output end of the cylinder pushes the fixed chassis to move upward, and the fixed chassis transmits power to the first positioning seat through the fixed column, thereby providing power for the pulling of the limit block and the support nut.

[0014] Through the above technical solution, the installation shaft can push the second fixed positioning seat to move upward, and use the inner top seat in the second positioning seat to squeeze the positioning clamp on the elastic connecting rod inward. Since the inner end face of the inner top seat is a hemispherical groove, when the inner top seat squeezes the positioning clamp on the elastic connecting rod inward, the elastic connecting rod will undergo a slight elastic deformation inward, and the positioning clamp will also shrink toward the center synchronously. When the inner end face of the inner top seat is tightly fitted with one side of the fixed box, the inner end face of the positioning clamp is also completely separated from the end face of the fixed box. At this time, when the quick-release fixing nut is pulled upward, the elastic connecting rod can be easily separated from the corresponding plug-in hole, thereby completing the quick release.

[0015] Furthermore, the lower end of the fixed box is fixedly connected to a mounting cylinder, a mounting cavity is opened in the mounting cylinder, a movable column is slidably connected in the mounting cylinder, the upper end of the movable column is fixedly connected to a guide plate, the end of the movable column away from the guide plate is fixedly connected to a top block, a second return spring is sleeved on the outer side of the movable column, one end of the second return spring is fixedly connected to the mounting cylinder, a positioning column is fixedly connected to the upper end of the fixed box, a positioning column is rotatably sleeved on the outer side of the positioning column with a locking block, and a torsion spring is installed between the locking block and the positioning column.

[0016] Through the above technical solution, the torsion spring installed between the blocking block and the positioning column can enable the blocking block to rotate back to its original position when the user lets go, thereby achieving height limitation of the guide plate.

[0018] Through the above technical solution, no matter whether it is a small animal or a pedestrian approaching the automatic alarm mechanism, the upper mounting plate slides downward due to gravity, and at the same time the third reset spring is squeezed and is in a compressed state, the upper electrode contact and the lower electrode contact contact each other, so that the current loop in the circuit is connected, and the buzzer alarm starts to emit a sharp alarm sound to scare away or drive away pedestrians or small animals approaching the communication tower.

[0019] Furthermore, a reinforcing rib is fixedly connected to the upper end of the tower body, a maintenance platform is fixedly installed on the upper end of the reinforcing rib, a guardrail is installed on the maintenance platform, a receiver is installed on the upper end of the maintenance platform, and a lightning rod is fixedly connected to the receiver.

The tool-free disassembly and assembly structure can easily disassemble the tower into parts that are easy to transport, and these parts can be quickly reassembled at the new installation site, greatly reducing the transportation process. The present invention reduces space occupation and transportation costs, and also improves the efficiency of moving the tower between different locations; (2) The present invention designs an automatic alarm mechanism. When a small animal or pedestrian passes by the automatic alarm mechanism, the upper mounting plate slides downward due to gravity, and at the same time the third reset spring is squeezed and is in a compressed state.

When the inner end face of the inner top seat 62 is tightly fitted with one side of the fixed box 2, the inner end face of the positioning clamp head is also completely separated from the end face of the fixed box 2. At this time, when the quick-install fixing nut 3 is pulled upward, the elastic connecting rod 31 can easily separate from the corresponding plug-in hole 18, thereby completing the quick release.
