Description

A steel pipe tower rod license plate suspension device

technical field

The invention belongs to the field of number plate suspension on tower poles, in particular to a number plate suspension device on steel pipe tower poles.

Background technique

The tower number plate is an important sign reflecting all aspects of the line. If there is no pole number plate or the pole number plate is unclear, it will cause great safety hazards to the operation and maintenance of the line. Due to the rapid development of the power grid, many lines are facing transformation, and a large number of pole number plates are adjusted and replaced every year. In addition, due to the quality problems in the production of pole number plates, the fading phenomenon of pole number plates has occurred, and many of them have become blurred and need to be replaced in time. At present, the number plate suspension of tower poles on the market, such as Chinese Patent Publication No.: CN105390064A, discloses a pole number plate mounting bracket, including a bracket body, slide rails, fasteners and fixing bars, and a card slot is arranged on one side of the bracket body , the bracket body is provided with fixing holes, and the bottom of the two sections of the slide rail is provided with installation holes. Fixed connection, two sliders with through holes are set in the slide rail, the two sides of one end of the fixed brace are provided with protrusions inclined to the other side of the fixed brace, the diameter of the raised part of the fixed brace is larger than that of the slider The diameter of the mounting hole in the rail. It is very simple to replace the number plate of an ordinary angle steel tower, but since the steel pipe tower has only one ladder for people to climb and grasp, it is more difficult to replace the number plate of the steel pipe tower. In addition, due to the different sizes of the number plates, it is difficult for the current bracket to adapt well to the number plates of different sizes, thus increasing the difficulty of installation.

Contents of the invention

The invention aims to overcome the deficiencies in the prior art, and provides a steel pipe tower rod license plate suspension device which is simple and convenient in the installation process and can adapt to license plates of different sizes.

In order to achieve the above object, the present invention adopts the following technical solutions:

A steel pipe tower rod license plate suspension device, including a license plate bracket and a mounting bracket, the license plate bracket includes a fixed end for fixing the license plate and a mounting end fixedly connected with the mounting bracket, the bottom of the fixed end is provided with Fixed lower clamping bar, the top of the fixed end is provided with an upper clamping bar that can move up and down relative to the lower clamping bar, the lower clamping bar is provided with a slider, and the upper clamping bar is provided with an upper gear And the lower gear that can be engaged with the upper gear for transmission, the lower clamping bar is provided with a fixed rack that cooperates with the lower gear, the slider is provided with a rotating rod that drives the upper gear to rotate, and the bottom of the upper clamping bar An upper chute is provided, and a locking pin for disengaging the upper gear and the lower gear is arranged in the upper chute.

In this way, when installing, the number plate moves inward along the lower clamping bar, pushes the slider to slide down the other end of the clamping bar, and the rotating rod connected with the slider will drive the upper gear to rotate, and the lower gear will also rotate synchronously to drive The upper clamping bar moves down. When the upper clamping bar moves down to contact with the upper edge of the number plate, the locking pin pushes up so that the upper gear and the lower gear are out of mesh, and the upper edge of the number plate enters the upper chute of the upper clamping bar for positioning. While continuing to slide the number plate inward, the upper clamping bar will no longer move downward. The distance between the upper clamping strip and the lower clamping strip can automatically adapt to the width of the number plate, and the installation process is simple and convenient, and can be completed with one hand, which improves the convenience of installation and the safety of workers when working at heights.

Preferably, the upper clamping bar is provided with an energy storage gear meshed with the lower gear, and a coil spring is provided on the energy storage gear. In this way, the lower gear will drive the energy storage gear to rotate when the lower gear rotates, and the coil spring will store energy after the energy storage gear rotates. When the number plate needs to be replaced, the coil spring releases the elastic potential energy, pushes the slider through the rotating rod, and pushes the number plate out, thereby It is convenient for the staff to take out the number plate smoothly.

As a preference, the bottom of the upper clamping bar is provided with a lower gear positioning seat for positioning the lower gear, and the lower gear positioning seat is provided with symmetrically arranged clamping hoops, and the lower ends of the two clamping hoops are rotatably connected. The locking pin is provided with a downwardly arranged action rod, and a connecting rod is provided between the lower end of the action rod and the upper end of the clamp hoop to lock the hoop inwardly to rotate the lower gear. In this way, when the locking pin moves up, it will drive the action rod to move up, and act on the clamping hoop through the connecting rod, so that the clamping hoops on both sides rotate inward, thereby clamping the lower gear for positioning, thereby ensuring the clamping up and down. The clamping and positioning effect of the strip on the number plate.

Preferably, the side of the positioning pin facing the opening end is provided with a guide slope, and the opening end of the lower clamping bar is provided with a sliding switch fixedly connected with the positioning pin, and the sliding direction of the sliding switch is the same as the sliding direction of the positioning pin. unanimous. The positioning pin can be pushed down by the slide switch, so that the positioning of the number plate can be released when the number plate is replaced.

Preferably, it also includes a U-shaped ring, the installation end and the installation bracket are located in the U-shaped ring, the opening of the U-shaped ring is provided with a mounting plate, and two ends of the U-shaped ring are respectively provided with nuts for positioning the mounting plate.

Preferably, the mounting end and the mounting bracket are provided with a communicating mounting hole, and bolts connecting the mounting end and the mounting bracket are provided in the mounting hole.

The beneficial effects of the present invention are: (1) The replacement process of the number plate is simple and convenient, which effectively saves man-hours for changing the number plate and improves the safety of the number plate installation; (2) can adapt to number plates of different widths and sizes, and is adaptable and versatile higher.
