Description

Technical Field

[0001] The utility model relates to a transmission tower with a sleeve-type reinforcement structure, belonging to the technical field of transmission towers. Background Technique

[0002] The transmission tower is the support point of the overhead line. Installing one circuit on the transmission tower is a single-circuit transmission tower, and installing two circuits on the transmission tower is a double-circuit transmission tower. A single circuit means a circuit with one power supply for one load; a double circuit means a circuit with two power supplies for one load. When installing a transmission tower, a reinforcement structure is usually required to reinforce it.

[0003] The utility model patent with the publication number CN219548558U discloses a sleeve-type reinforcement device for a transmission tower, including a reinforcement box. The electric push rod that sleeves the reinforcement box around the foot pole of the tower drives the reinforcement box and the bottom elastic connecting plate to contract and adjust simultaneously to the outside or the inside. The reinforcement box can provide wind resistance protection for the foot pole. The wireless inclinometer monitors the reinforcement box connected to the foot pole, and the warning light can emit warning lights to further enhance the alarm effect and remind the on-site staff to repair and maintain in time. Pass the foot of the tower through the reinforcement opening, and the meshing gear adjusts the tooth cylinder to move to the outside or the inside simultaneously, which can well adjust the length of the tooth cylinder according to the diameter of the tower foot pole, facilitating the automatic clamping and reinforcement of the transmission tower. The angle of the fixed plate can be adjusted through the damping rotating shaft, and the fixing bolt is screwed into the tower foot pole to increase the connection stability between the fixed plate and the foot pole. When the above device is in use, it can only fix the two sides of the tower foot pole, resulting in poor stability of the device for the tower. At the same time, when the device is damaged, the whole device needs to be replaced, resulting in low practicability of the device. Content of the Utility Model

[0004] The purpose of the utility model is to provide a transmission tower with a sleeve-type reinforcement structure. The utility model can fix and support the tower foot pole at multiple angles and is convenient for disassembling and replacing the device, thus effectively improving the practicability of the device to solve the problems raised in the above background technique.
