Abstract

PURPOSE: A rotary post bar is provided to reduce power consumption by powering the post bar using a small drive motor and to reduce maintenance costs by facilitating installation and maintenance work. CONSTITUTION: A rotary post bar comprises a motor(41), a bevel gear(43), a worm gear(44), a universal joint(42), and rotation angle detection limit switches(51). The motor is formed inside a fixed post(10). The bevel gear and the worm gear connect the motor and the universal joint to each other. The universal joint is connected to a rotary post(30). The rotation angle detection limit switches are formed inside a fixed socket(10-1) and a rotary socket and sense the rotation speed and angle of the rotary post.

Description

Revolving props {a revolving prop}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a rotary strut, in particular, in the configuration of a rotary strut in which the strut rotates, the worm and the worm gear are double-acted as a means for rotating the strut, and thus a universal joint or shaft It is possible to selectively install two methods, and to enable the props with traffic lights or signs to rotate according to the user's request through power transmission using them. One would be to choose a ratio.

In the case of a traffic light that enables a sign or a vehicle to be recognized, a traffic light or a sign located on the road is kept at a distance of 5.8 m from the ground in consideration of the speed of the vehicle and the height of the vehicle passing through.

The above ground clearance does not interfere with the operation of a general vehicle, but in the case of special vehicles and special structures in which the height of the vehicle and the cargo loaded on the vehicle exceeds this, the operation of the vehicle is restricted by signs or signals. This occurred.

As a means for solving the above problems, a rotary signal light is provided to rotate the upper side of the support so that the flashing light can rotate, and as a driving means for rotating the support, a hydraulic motor is formed on the outside of the support and divided into posts. In the case of driving device using hydraulic motor, the driving device is exposed to the outside, so durability and pollution are reduced due to oil leakage due to corrosion and wear. There is a problem that the installation of the surrounding structure is hindered by the drive device installed outside the traffic light, and invented and used his own invention registration number 10-1013771, but due to the characteristics of the structure of the shaft consisting of single acting In the event of a strong impact, the axle will wear out and will need to be repaired or replaced. There is a problem that occurs if it occurs.

The present invention is to enable the props provided with the flashing lights or signs constituting the traffic light to rotate, the drive means for rotating the props while providing the props that are not limited to the movement of special vehicles or special structures to be formed inside the props The purpose of the present invention is to provide a durable support stand without disturbing the structure around the support stand.

The present invention is a means for solving the above problems, by improving the means for driving the rotary support in the rotary support, to install the worm and worm gear (double gear) in double acting means for rotating the rotary support and the rotary shaft universal joint It is to provide a rotatable prop which can be selectively installed in a universal joint or a shaft and transmits power using the same.

The strut of the present invention is effective to facilitate the movement of logistics without restricting the passage of special vehicles or special structures, while performing the function of installing the usual signs or traffic lights, so that the driving means is installed inside the strut Its simple configuration does not interfere with the structure around the struts, and it is easy to install and manage the drive system, which reduces the cost of installing and maintaining the rotary struts. It is not exposed to the outside and is beautiful in appearance, and can be operated manually and automatically by simple operation as well as the rotation angle can be rotated 360 degrees, even after installation of traffic lights and other signs There is no obstacle and the structure which drives rotating prop is composed of double acting inside the traffic light. Joe durable and robust and wear resistance is excellent, but that an effect of increasing the durability holding units.

The present invention is composed of a fixed support (10) fixed to the ground and a rotating support (30) formed with a flashing light (20) or a sign 20-1, a rotary support (30) driven by the power of the motor 41 It is a configuration of the rotary prop 40 to change the angle of the flashing light 20 through the rotation of the).

Looking at the characteristics of the present invention by connecting to the fixed socket 10-1 formed on the fixed support 10 and the rotary socket 30-1 formed on the rotary support 30, the rotary socket (by the bearing 40-1) 30-1) to rotate while being in close contact with the fixed socket (10-1),

The fixed socket 10-1 and the rotary socket 30-2 are provided with a rotation angle detecting limit switch 51 so as to detect a rotation angle, and a fixed pillar by means of rotating the rotary pillar 30. (10) A bevel gear 43 and a worm gear 44 which are formed inside and provide power to the motor 41 and connect the motor 41 and the universal joint 42 to both sides are installed. Universal joint 42 is to be connected to the rotary support 30, characterized in that configured to rotate to the rotary support 30 by the drive of the motor (41).

In another embodiment, the fixed socket 10-1 and the rotary socket 30-2 are formed in the fixed support 10 by a means for rotating the rotary support 30 to provide power. 41, a pair of bevel gears 43 and worm gears 44 connecting the motor 41 and the shaft 50, and the shaft 50 to be connected to the rotary strut 30 , Characterized in that the rotation to the rotary support 30 by the drive of the motor (41).

In this way, the rotary support 30 formed on the fixed support 10 rotates, and thus, in detail by the accompanying drawings, the rotary support post 40 in which the position of the signal flashing light 20 or the sign 20-1 is adjusted. The explanation is as follows.

As shown in Figure 1 is composed of a fixed support (10) fixed to the ground and a rotating support 30, which is formed a flashing light 20 or sign 20-1, fixed for the rotation of the rotary support 30 It is connected to the socket (10-1) and the rotary socket (30-1).

Referring to the operation of the present invention, when the motor 41 operates by applying power to the motor 41 formed in the fixed support 10, a pair connected to the pair of bevel gears 43 connected to the motor 41 The direction of the power of the motor 41 is changed by the worm gear 44 of the rotary shaft, and the rotary socket 30-through the universal joint 42 or the shaft 50 to which the power of the changed motor 41 is selectively installed. Since it is transmitted to 1), the power of the motor 41 is transmitted to the rotary socket 30-1 even in the narrow rotary socket 30-1.

Since the rotary socket 30-1 rotating as described above is fixed to the rotary support 30 by the fixing bolt 40-2, the rotation of the rotary socket 30-1 is connected to the rotation of the rotary support 30. It rotates in the state which contact | connected securely to the fixed socket 10-1 by the bearing 40-1 of the rotary socket 30-1.

The present invention uses the worm gear 44, the bevel gear 43, and the universal joint 42 or the shaft 50, which is a means for rotating the rotary support 30, and the power transmission is easy, so that the driving means is mechanically Compared with the drive means which is configured and driven electronically, no trouble or error occurs, and thus the reliability of the product can be secured.

The present invention uses the user panel 40-3 provided in the rotary support base 40 to rotate the rotary support 30, as shown in FIG. 30) It is possible to adjust the rotation direction and the rotation interval, so that the use of the rotary prop 40 is convenient for the user to manually set and press the rotary button when the traffic light moves to the desired position when the button is reached When it is released, the rotation stops, and if it is set automatically, pressing the rotation button automatically stops after moving up to the angle set by the rotation angle detection limit switch 51, and pressing the return button automatically returns to the original position and stops. will be.
