Manual drainage plate fastening device

Abstract

The invention relates to an improvement of a bolt loading and unloading tool for a drainage plate, in particular to a manual fastening device for the drainage plate. It includes an upper clamping piece and a lower clamping piece opposite to each other. The upper clamping piece is rotatably installed in the transmission box. The transmission box is fixedly connected to one side of the power box. The main shaft; the driven gear is fixedly connected to the upper clamping piece, which is connected with the driving gear at the upper end of the main shaft; the lower end of the main shaft is fitted with a threaded sleeve; the lower end of the power box has a longitudinally arranged chute, and a support arm is slidably installed in the chute. The lower clip is installed on the outer end of the support arm, and the inner end of the support arm is provided with a threaded sleeve matched with the threaded sleeve. The fastening device can not only work live, but also fast fasten, has a high degree of automation, is easy to operate, greatly reduces labor intensity, and improves labor efficiency.

Description

technical field [0001] The invention relates to an improvement of a bolt loading and unloading tool for a drainage plate, in particular to a manual fastening device for the drainage plate. Background technique [0002] The diversion plate is the part connected by the diversion line, the hanging wire string and the parallel ditch clamp in the power transmission line. It is made of two rectangular aluminum plates and then passed through the corresponding through holes on the two plates through the screw and fixed with a nut. Ring spacers and elastic spacers are sleeved on the top. In order to be more difficult to loosen, sometimes two nuts are set on the upper end of the screw rod. After a period of operation of this kind of diversion plate, the nut is often loosened and the contact surface is oxidized due to thermal expansion and contraction, which leads to the increase of the contact resistance of the diversion plate and the parallel groove clamp. When the current load passi...

However, this improvement still requires intermittent and continuous reciprocating pulls, which does not significantly increase the fastening speed and reduce labor intensity; at the same time, due to the addition of an insulating operating rod, the operating distance is extended and the safety performance is improved. Eliminates the difficulty of quickly aligning the socket with the nut and tires the eyes
