Description

Special clamp for angle steel tower sign board

technical field

The invention relates to a sign board installation tool, in particular to a special fixture for a power supply angle steel tower sign board with convenient installation, firm fixation and wide application range.

Background technique

At present, the "Standards for Safety Facilities of the State Grid Corporation" has detailed regulations on the drawing parameters of transmission line signs (including tower signs, prohibition signs, and phase signs), but the fixing fixtures of the signs are all made by ourselves. . The existing fixing fixture is made of one straight flat steel plus two right-angle flat steels welded and bolted. When installing, it is often limited by the inconsistency of the angle steel specifications, and there is a certain degree of contact between the right-angle flat steel and the angle steel. Gaps are prone to loosening. When replacing the tower signboard, it is necessary to loosen multiple bolts when removing the original fixture. The work efficiency is low, and it cannot meet the standardization requirements of the tower safety facilities.

Contents of the invention

The object of the present invention is to overcome the shortcomings of the above-mentioned prior art, and provide a special clamp for angle steel tower sign boards which is convenient to install and dismantle, reliable to fix, and has a wide application range.

The present invention can reach through following measures:

A special jig for angle steel tower signs, characterized in that it includes a right-angled fixing body, a U-shaped fastening body, a right-angled support body, a connecting baffle and a connecting rod, one side of the right-angled support body is provided with a connecting hole, and the other One side is connected to the right-angled fixed body in a W shape, the connecting baffle is welded to the inner corner of the right-angled fixed body and divides the right-angled fixed body equally, one end of the connecting rod is fixedly connected to the connecting baffle, and the U-shaped fastening body passes through the bottom edge The opening of the provided connecting hole is sheathed on the connecting rod towards the rectangular fixed body, the connecting hole deviates from the middle of the U-shaped fastening body and is close to one side, and the other end of the connecting rod is provided with a connecting thread and a fastening nut.

A flat washer or a spring washer is arranged under the fastening nut of the present invention to improve connection reliability.

The present invention is a special tool designed for installing and fixing signs on a power supply tower with an angle steel structure. There are two available slots on the right-angled fixing body, and the U-shaped fastening body has a fastening clamp plate on the bottom surface perpendicular to the direction of the connecting rod and a Fastening clips with an angle greater than 90° with the fixed clips larger than the bottom surface can be transformed into a variety of connection methods, so that they are not restricted by the horizontal, vertical, or oblique position of the angle steel, and are not limited by the angle steel opening facing inward, Restrictions of different orientations such as outward, upward, and downward can be firmly fixed to complete the installation of signboards and meet different types of signboards (including tower signboards, prohibition signboards, phase signboards) installation requirements.

Detailed ways

The present invention will be further described below in conjunction with accompanying drawing:

As shown in the figure, a special fixture for angle steel tower signs is characterized in that it includes a right-angled fixing body 1, a U-shaped fastening body 2, a right-angled support body 3, a connecting baffle 4 and a connecting rod 5, and the right-angled support body One side of 3 is provided with a connection hole, and the other side is connected with the right-angled fixed body 1 in a W shape, and the connecting baffle plate 4 is welded on the inner corner of the right-angled fixed body 1 and divides the right-angled fixed body 1 equally, and connects The included angle between the baffle plate 4 and the two sides is the same, which is 45°. One end of the connecting rod 5 is fixedly connected with the connecting baffle plate 4, and the U-shaped fastening body 2 is opened towards the right-angled fixed body 1 through the connecting hole opening provided on the bottom edge. Set on the connecting rod 5, the connecting hole deviates from the middle of the bottom edge of the U-shaped fastening body 2 and is close to one side, the other end of the connecting rod 5 is provided with a connecting thread and a fastening nut 6, and a flat washer is provided under the fastening nut 6 or spring pads to improve the reliability of the connection.

In the present invention, the right-angled fixed body 1 has two available draw-in grooves, and the U-shaped fastened body 2 has a vertically fixed clamping plate and an obliquely fixed clamping plate, which are used to be stuck on two right-angled sides of the angle steel, and can be converted into multiple When installing the sign board, the operator puts the connecting screw, flat washer, and spring pad between the sign board bracket and the special fixture in advance, tightens the nut (but do not screw it dead), and then observes the position to be installed Arrange the direction of the angle steel and the orientation of the opening, and then clamp the right-angle fixed body 1 and the U-shaped fastening body 2 on the two right-angle sides of the angle steel, and check whether they can be completely matched and stuck. If the fit is not good, you can rotate the U U-shaped fastening body 2, adjust the slot position of right-angled fixed body 1 or the upper and lower positions of right-angled fixed body 1 and U-shaped fastening body 2, etc., until they can be completely matched and stuck, and then put on flat pads or spring pads in turn . After screwing the nut 6, the signboard is rotated by connecting bolts between the bracket and the special clamp until the nut is screwed to the requirements, and the installation of the signboard is completed. The present invention is a special tool designed for installing and fixing signboards on power supply towers of angle steel structure, which can be transformed into various connection modes, so that it is not restricted by the horizontal, vertical, or oblique positions of the angle steel, and is not limited by the arrangement of the angle steel. The restrictions of different orientations such as opening inward, outward, upward, and downward can be firmly fixed to complete the installation of signs and meet the requirements of different types of signs (including tower signs, prohibition signs, phase sign plate) installation requirements.
