Technical Field

The invention relates to the field of tower crane standard knot connecting bolts, in particular to a tower crane standard knot bolt fixing device.

Background

In the current building engineering, the conventional protection method of the standard section connecting bolt of the tower crane is that the standard section connecting bolt is directly exposed in the air, and when the bolt is fastened, if the screw rod freely rotates, two special wrenches are required to be matched with each other to screw the nut.

However, the prior art has the following defects: the loosening of the standard section bolt of the tower crane is frequent and is a direct factor influencing the safe operation of equipment, when a maintenance worker fastens the nut in daily life, if the screw rotates freely, the screw head needs to be fixed by one wrench, and then the nut is screwed by the other wrench, so that the difficulty of operation in high altitude is high, and the danger coefficient is high. The invention provides a tower crane standard knot bolt fixing device and aims to solve the problems.

The prior Chinese patent document CN201920134423.0 discloses a fastening device with an anti-corrosion function for a tower crane standard knot bolt, and the main technical scheme is as follows: a fastening device with an anti-corrosion function for a tower crane standard knot bolt comprises a square device body, wherein a first through hole for a standard knot to pass through is formed in the device body, the device body is divided into a first L-shaped steel plate and a second L-shaped steel plate in two parts by a diagonal line, the joint of the first L-shaped steel plate and the second L-shaped steel plate is detachably connected, the first L-shaped steel plate and the second L-shaped steel plate are respectively provided with a second through hole for a standard knot connecting bolt to pass through, a bolt cap of the bolt is sleeved on the bolt cap of the bolt, the bolt cap is positioned on the upper surfaces of the first L-shaped steel plate and the second L-shaped steel plate, a plurality of hinges are arranged on the device body, the hinges are uniformly distributed at four edges of the bottom surface of the device body or on four outer end surfaces of the device body, one hinge sheet of each hinge is connected on the device body, another hinge piece of hinge on detachably even has transparent waterproof cloth, the lower extreme of transparent waterproof cloth even has the magnet that the surface cover has the rubber cork, magnet adsorbs on standard festival support body, the hinge with transparent waterproof cloth will the lateral surface of standard festival surrounds. The technical problems and main technical schemes are different from those solved by the invention.
