Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of transmission line ladder auxiliary technology, in particular to a 110kV transmission line ladder tightener. Background Art
[0002] The routine maintenance of power transmission lines frequently uses soft ladders, such as adjusting the anti-vibration hammer, repairing the conductor, replacing the composite insulator and equipotential work (live work). The function of the soft ladder is to allow the operator to climb up the conductor from the ground. Usually, the operator needs to climb up the conductor from the ground and fix the ladder during the operation. People press and pull the soft ladder to ensure that the soft ladder does not float. This operation method has the problem of high labor intensity for ground personnel, and the soft ladder is fixed directly below the operation point, which is prone to safety hazards such as falling objects from high altitude and injuring people. At present, most of the soft ladders used on 110kV transmission lines are composed of three parts: the ladder head, the ladder body and the ladder tail hook. The ladder head is mainly fixed to the tower body by two methods: double hanging rings. The double hanging ring fixing method is simple to hang, but the ladder cannot be fastened to the tower material, and the safety factor is not high. It is very unsafe for workers to use this soft ladder, and it is easy to fall.
[0003] After searching, the Chinese patent with the announcement number of CN206272151U discloses a 110kV transmission line ladder tightener, including a buckle, a housing, a rotating mechanism and a braking mechanism, wherein the buckle is fixed on the housing, a first fixed shaft is provided in the housing, a rotating mechanism is installed on the first fixed shaft, the rotating mechanism includes a ratchet gear, a second fixed shaft is provided above the first fixed shaft, a braking mechanism is installed on the second fixed shaft, the braking mechanism includes a pawl, the pawl cooperates with the ratchet gear, a rope inlet is provided on the side wall of the housing, guide plates are provided above and below the rope inlet, and the end of the guide plate is between the rotating mechanism and the braking mechanism. The advantage of the utility model is that the installation rope of the ladder inserted into the rope inlet can be placed between the rotating mechanism and the braking mechanism by opening the braking mechanism, and the installation rope of the ladder can be stuck after the braking mechanism is closed. After the installation rope of the ladder is stuck, the handle is moved to rotate the ratchet gear to tighten the installation rope of the ladder, and the installation of the ladder is completed, which is convenient, fast and time-saving.
[0004] When this patent is actually used, there are the following defects:
[0005] In this patent, when the ladder tightener needs to tighten the ladder, the rotating handle drives the ratchet gear to rotate, but the ladder is squeezed and limited by the pawl, and when the ratchet gear rotates clockwise, the ladder follows the direction of the ratchet teeth, resulting in slippage, thereby reducing the tightening effect of the ladder tightener on the ladder. Utility Model Content

[0012] Furthermore, the gears are rotatably mounted on both sides of the inner wall of the shell, and the gears are connected to the one-way ratchet.
[0013] The arranged gear can drive the rotating shaft to rotate relatively, thereby increasing the tightening effect of the rotating shaft on the rope of the soft ladder.
[0014] Furthermore, the rotating shaft is fixedly installed between the gears, and the anti-slip ring is fixedly installed on the outer surface of the rotating shaft.
[0015] The anti-skid ring can increase the friction between the rotating shaft and the ladder rope, thereby increasing the tightening effect of the ladder tightener on the ladder.
