Description

Technical Field

[0001] The present invention relates to the field of communication towers, and particularly to a communication tower with a retractable operation platform. Background Art

[0002] An antenna support is installed at the top of the communication tower body. The antenna support is used to install antennas for communication. The antennas need to be maintained regularly to ensure the stability of communication. To maintain the antennas, a rest platform or an operation platform is generally installed on the communication tower, so that maintenance personnel can stand on the operation platform to repair the antennas. For example, a 5G network communication tower with the application number 202122730187.9 has a rest platform welded to the communication tower. Such a rest platform is prone to rusting when exposed to the sun and rain for a long time, affecting the firmness of the rest platform. The rest platform has a relatively single function. Since it is welded around the communication tower in a ring shape, it is not convenient to install other external devices on it. Summary of the Invention

[0003] The present invention aims at the deficiencies in the prior art and provides a communication tower with a retractable operation platform.

[0004] To solve the above technical problems, the present invention is solved by the following technical solutions:

A support seat is installed on the tower body below the antenna support. An operation platform is installed on the support seat. The support seat is provided with at least four support blocks extending outward. The support blocks are evenly distributed around the tower body. A guide rail frame is installed on the tower body above the support seat. An upper guide rail groove is provided on the guide rail frame. A lower guide rail groove is provided on the support seat. The upper guide rail groove and the lower guide rail groove form a C-shaped lower rail groove. The operation platform includes a number of guide rollers and a support cloth laid on the guide rollers. The guide rollers are all fixedly connected to the support cloth. All the guide rollers are connected in series by ropes. One end of the guide roller slides in the lower rail groove through a first roller. The support cloth unfolds to form a fan shape and wraps around the tower body. The other ends of some of the guide rollers are supported on the table tops of the support blocks. The operation platform can be folded and stored on the support seat. The operation platform is foldable. When maintenance is not required, the operation platform can be folded and hidden to avoid being exposed to the sun and rain, thereby extending the service life of the operation platform. The support seat is used to reinforce the strength of the welded joint of the two tower bodies on the one hand, and to support a number of guide rollers on the other hand, improving the support strength of the operation platform and ensuring the stability of maintenance personnel on the operation platform.

[0006] Preferably, the operating platform includes a positioning frame and a driving frame. All guide rollers are arranged between the positioning frame and the driving frame. One end of the support cloth is fixed to the positioning frame, and the other end is connected to the driving frame. The positioning frame is fastened to one of the support blocks by screws, and the driving frame slides on the lower track groove through the first roller. The positioning frame is used to position the guide rollers and the support cloth at one end, and the driving frame is a movable frame that can drive the guide rollers and the support cloth to move circularly, thus facilitating the folding and unfolding of the operating platform.

[0007] Preferably, it includes a rubber gear ring and a connecting member. There is a first notch in the middle of the side of all support blocks. A guide gear is installed in the first notch and is connected to the support block by bolts. The rubber gear ring is wound around all guide gears and meshes with them. A driving motor is installed on the seat body of the support seat, and a driving gear is installed on the output shaft of the driving motor. The driving gear meshes with the rubber gear ring, and the rubber gear ring is fixedly connected to the driving frame through the connecting member. When the operating platform needs to be unfolded in a fan shape, the driving motor can drive the rubber gear ring to rotate, and the rubber gear ring can drive the driving frame to move through the connection, thus realizing the automatic unfolding and storage of the operating platform. The rubber gear ring is installed on the guide gears on the support blocks, and the rubber gear ring surrounds the support seat. The guide gears are installed stably, so that the rotation of the rubber gear ring is stable.

[0008] Preferably, the connecting member is a connecting rod. The lower end of the connecting rod is fixed to the rubber gear ring by screws, and a guide wheel is installed at its upper end. A C-shaped track is fixed to the lower end surface of the driving frame, and the guide wheel is limited to move within the C-shaped track. A nut made of metal is embedded in the rubber gear ring, and the screw is threadedly connected to the nut.

[0009] Preferably, an upper track is welded on the tower body. The upper track surrounds the tower body, and an upper track groove in the shape of C is provided on the upper track. A safety buckle slides in the upper track groove. The safety buckle includes a locking ring, a connecting shaft and a second roller. One end of the connecting shaft is welded to the locking ring, and the other end is connected to the second roller. The safety buckle is used to lock the safety rope of the maintenance personnel. When the maintenance personnel walk on the operating platform, the safety rope can drive the safety buckle to move together, improving the safety of the maintenance personnel.

[0010] Preferably, a second notch for the second roller to pass through is provided at the upper end of the upper track. An arc-shaped cover plate is installed at the second notch. The cover plate is connected to the upper track by screws. The cross-sectional shape of the cover plate is "convex" shaped. The small end of the cover plate extends into the second notch, and the end surface of the small end of the cover plate is flush with the upper track surface at the upper end. The second notch is an installation port, which facilitates people to install other components such as safety buckles in the upper track groove.

[0011] Preferably, a rain shield made of metal and used for accommodating the operation platform is installed on the upper track. The rain shield is an arc-shaped rain shield. An accommodating groove with an arc shape is provided at the lower end of the rain shield. When the operation platform is accommodated, both the support cloth and the guide roller are hidden in the accommodating groove. A shaft rod is fixed on the rain shield, and a third roller is installed on the shaft rod. The third roller slides in the upper track groove of the upper track. When the operation platform is accommodated, the rain shield covers above the operation platform, preventing the operation platform from being exposed to the sun and rain, and improving the service life of the operation platform.

[0012] Preferably, a tool groove is provided at the upper end of the rain shield. The bottom surface of the tool groove is an inclined surface. The depth of the tool groove gradually increases from one end to the other end. A water passing hole is provided on the side wall at one end of the tool groove. The water passing hole is provided at the low end of the inclined surface. The width of the water passing hole is the same as the width of the tool groove. Another function of the rain shield is to place the tools for maintenance by maintenance personnel, preventing the maintenance tools from falling from the operation platform. The bottom surface of the tool groove is inclined, facilitating the rapid discharge of rainwater from the water passing hole.

[0013] Preferably, a lock hole is provided on the other side wall of the tool groove. A rope is connected between the lock hole and the lock ring. When maintenance personnel are performing maintenance, they need to walk on the operation platform. Through the connection of the tool groove with the lock ring by the rope, the tool groove can move along with the maintenance personnel, facilitating the maintenance personnel to pick up and place tools.

[0014] Preferably, the support base includes a left seat body and a right seat body. Left fixing plates are fixed at both ends of the left seat body, and right fixing plates are fixed at both ends of the right seat body. The left fixing plate and the right fixing plate are tightly connected by bolts. At least two support blocks are fixed on both the left seat body and the right seat body. The split-type support base is convenient for installing it on the communication tower.

[0015] Due to the adoption of the above technical solutions, the present invention has remarkable technical effects:

[0016] The operation platform is foldable. When maintenance is not required, the operation platform can be folded and hidden, thus avoiding being exposed to the sun and rain, and prolonging the service life of the operation platform. On the one hand, the support base is used to reinforce the strength of the welded part of the two tower bodies, and on the other hand, it is used to support multiple guide rollers, enhancing the support strength of the operation platform and ensuring the stability of maintenance personnel on the operation platform.

A communication antenna is installed on the antenna support 11. A support base 12 is installed on the tower body 10 below the antenna support 11. The support base 12 is fastened to the tower body 10 by bolts. The support base 12 surrounds the top of the tower body 10. An operating platform 13 is installed on the support base 12. The operating platform 13 is used to facilitate maintenance personnel to stand for maintenance and provide a support surface. At the same time, it is also convenient for maintenance personnel to take a short rest on the operating platform. The support base 12 is provided with at least four support blocks 121 extending outward. In this embodiment, the number of support blocks 121 is four, and the four support blocks 121 are evenly distributed around the tower body 10. A guide rail frame 14 is installed on the tower body 10 above the support base 12. Card slots are provided around the tower body 10. The guide rail frame 14 is positioned and installed around the tower body 10 through the card slots. An upper guide rail groove 141 is provided on the guide rail frame 14. A lower guide rail groove 122 is provided on the support base 12. The upper guide rail groove 141 and the lower guide rail groove 122 form a C-shaped lower track groove 100. The operating platform 13 includes a number of guide rollers 131 and a support cloth 132 laid on the guide rollers 131. The guide rollers 131 are guide rollers supported by metal. The support cloth 132 can be an oilcloth. The guide rollers 131 are all fixedly connected to the support cloth 132. A number of clamping blocks are sewn at both ends below the support cloth 132. The support cloth 132 is clamped and connected to the guide rollers 131 through the clamping blocks. All the guide rollers 131 are connected in series by ropes. One end of the guide roller 131 slides in the lower track groove 100 through a first roller 133. The support cloth 132 unfolds to form a fan shape and surrounds the tower body 10. The other ends of a part of the guide rollers 131 are supported on the table surfaces of the support blocks 121. The guide rollers 131 do not rotate relative to the support blocks 121, that is, the guide rollers 131 do not rotate by themselves. A gap is provided between adjacent guide rollers 131. When the support cloth 132 covers the guide rollers 131, a depression area will be formed. The depression area can increase the friction force and prevent maintenance personnel from slipping on the operating platform. When the operating platform 13 is needed, the operating platform 13 unfolds in a fan shape and surrounds the tower body; when the operating platform 13 is not needed, the operating platform 13 can be folded and retracted, and the operating platform 13 can be folded and retracted on the support base 12.

[0049] The operating platform 13 includes a positioning frame 134 and a driving frame 135. Both the positioning frame 134 and the driving frame 135 are made of metal. All the guide rollers 131 are arranged between the positioning frame 134 and the driving frame 135.
