Description

Street light with tilting function {STREET LIGHT WITH TILTING FUNCTION}

The present invention is installed on roads or bridges to provide lighting to pedestrians and drivers of vehicles, and more specifically, a tilting function capable of easily adjusting the installation height of streetlights so as not to interfere with the passage of pedestrians and drivers is provided. It's about streetlights.

In general, streetlights are lighting facilities that are erected at a certain distance along the side of the road for safety and security of road traffic, and are installed and used in various places such as highways, major roads in urban areas, bridges, commercial areas, residential areas, and parks. High-pressure mercury lamps, fluorescent lamps, sodium lamps, and incandescent lamps are used for street lamps.

In addition, it can be classified according to the way the lamps are installed on the streetlights.A highway type that installs a lamp at the end of a bent top of a streetlight column, a bracket type that installs a light with a branch extending horizontally at the upper end of the streetlight column, and the top of the streetlight column. The main head type, which installs a light, is typically used.

Safety checks are performed regularly or at any time according to the installation time and location of the streetlights. To this end, as shown in FIG. 1, most of the workers boarded the high-altitude vehicle and performed the work while being located at the upper level of the streetlight. In order to prevent pedestrians and vehicles from approaching the vicinity of the aerial vehicle, safety checks were conducted with the surrounding traffic controlled.

Accordingly, there was a problem that workers were inevitably exposed to a dangerous work environment, and pedestrians and drivers had a problem that they could not help but feel a lot of inconvenience in passing.

On the other hand, in the case of a street light installed on a bridge, as shown in Fig. 2A, there are problems such as danger of the worker and inconvenience of passage for safety inspection and maintenance of the street light, as well as obstacles to the safety inspection of the bridge. There was a problem acting as a factor.

In other words, for the safety inspection and maintenance of the bridge, an inspection workbench that is formed so that a worker can ride and move on the inspection vehicle moving on the road is installed, and after placing this inspection workbench on the outer or lower side of the bridge, the inspection vehicle The inspection workbench moved the bridge along this driving direction and safety inspection was performed.

However, as shown in Fig. 2b, the streetlights installed at regular intervals on the bridge act as a factor that hinders the movement of the inspection workbench by the inspection vehicle, so the position of the inspection workbench is moved so as not to interfere with the streetlights, and then the bridge can be inspected again. It was necessary to perform the inspection while repeating the process of positioning it so that it took a lot of time for the inspection work of the bridge, and there was a problem that the efficiency of the work was remarkably deteriorated.

Therefore, in the prior art, in order to perform safety inspection and maintenance of streetlights without moving the aerial vehicle, and to prevent interference even during safety inspections of bridges, many studies have been made to adjust the installation height of streetlights. .

For example, as in Korean Patent Laid-Open Publication No. 10-2007-0019446, the upper part of the post for street lamps is configured to rotate around the hinge axis, so that when the life of the street lamp is over or a breakdown occurs, the lighting unit is rotated downward to be close to the ground. And, after the inspection and repair work is completed, a folding-type street lamp post and a repair method for the post have been proposed by rotating upward to maintain the original shape.

However, as shown in FIG. 3, the conventional folding type street lamp post can rotate in the vertical direction by inserting the hinge shaft 107 into the hinge pipes 107a, 107b, and 107c, but the hinge pipe rotates in the vertical direction. During the process, it is composed of a structure that cannot withstand the force applied in both directions, and there is a problem that the hinge pipe and the hinge shaft may be easily deformed or damaged.

In addition, as the part in which the post is rotated, as well as a number of bolts 112 and nuts 113 installed on the upper and lower flanges 103 and 110 to limit the rotation of the post, are exposed to the outside, climate It is inevitable to be susceptible to corrosion or external shocks caused by changes, and for this reason, there is a problem that inspection and repair work of parts for rotating and fixing the posts must be performed more frequently.

In addition, as the inconvenience of repeatedly separating and coupling a plurality of bolts 112 and nuts 113 fastened to the upper and lower flanges 103 and 110 each time an inspection work is carried out, the efficiency and convenience of work There was a problem that this remarkably deteriorated.

If it is installed properly, '

'It is desirable to have a shape.

The movable bracket 32 is fitted with a support piece 31a at the lower end of the movable column 10 so as to be in contact with each other so that a plurality of movable pieces 32a are provided so as to be spaced apart from each other so as to protrude downward, and the movable piece ( 32a) Each of the movable holes 32b is formed to be positioned on a straight line.

' 형상으로 형성된 것이 바람직하다.At this time, the movable piece (32a) can be fitted with the support piece (31a) provided in the support bracket (31)

It is preferable that it is formed in a'shape.

Here, the reason why the support piece 31a and the movable piece 32a are interdigitated and installed so that they are in contact with each other is that the presence or absence of the rotational motion and the rotational speed are adjusted by the fastening force of the fastening shaft 33 to be described later, and When a force is applied in the direction other than the vertical direction during the rotational operation of the house part 20, the support piece 31a and the movable piece 32a remain supported to each other so that the movable column part 20 stably rotates up and down. It is to make it possible.

The fastening shaft 33 is adjusted so that the support hole 31b and the movable hole 32b are positioned in a straight line by fitting the support bracket 31 and the movable bracket 32 to each other, and then the support hole 31b and the movable hole It is inserted into (32b) and fastened.

The fastening shaft 33 is formed so as to adjust the clamping force while being inserted into the support hole 31b and the movable hole 32b to control the pressure at which the support piece 31a and the movable piece 32a are in contact with each other.

Through this, it is possible to firmly maintain the state in which the support bracket 31 and the movable bracket 32 are engaged with each other, as well as by controlling the rotational speed of the movable column part 20 so that the movable column part 20 It is possible to stably rotate around the (31b) and the movable hole (32b), it is possible to ensure the safety of the operator and prevent damage to surrounding objects when the movable holding unit 20 rotates downward.

The holding rotation limiting unit 40 is installed at least one of the fixed holding unit 10 or the movable holding unit 20 to be spaced apart from the rotational height adjustment unit 30 by a predetermined distance, so that the movable holding unit 20 is set. It is formed so that it can be rotated at an angle or maintained in an erected state stably.

The holding rotation limiting unit 40 is preferably composed of a downward rotation limiting member 41 and an upward rotation limiting member 42. First, the downward rotation limiting member 41 is a fixed column 10 as shown in FIG. 6A. ) Or installed to be located on one side of the rotary height adjustment unit 30 in either of the movable posts 20, and movable by supporting one side of the movable piece 32a or the outer surface of one side of the movable posts 20 It is formed to maintain a state in which the holding portion 20 is rotated downward at a set angle.

When such a downward rotation limiting member 41 supports the outer surface of one side of the movable column part 20, the upper surface of the downward rotation limiting member 41 is formed in a shape corresponding to the outer shape of the movable column part 20 to be movable. It is desirable to stably support the downwardly rotated state of the holding part 20.

Although not shown, the downward rotation limiting member 41 may be applied with a damper provided with a function capable of mitigating the impact encountered when the movable column part 20 is rotated downward at a set angle. By supporting the outer surface of the movable support part 20 which is rotating downward from the height, the movable support part 20 gradually rotates downward, and at the same time, the impact applied to the movable support part 20 having the downward rotation completed may be minimized.

The upward rotation limiting member 42 is installed to be located on the other side of the rotational height adjustment unit 30 on either the fixed column 10 or the movable column 20, as shown in FIG. 6B, When (20) is rotated upward to a set angle and erected, it is supported in a state spaced apart between the upper surface of the fixed column part 10 and the lower surface of the movable column part 20 so that the movable column part 20 exceeds the set range. It is designed to limit upward rotation.

In the accompanying drawings, the upward rotation limiting member 42 is shown to limit the upward rotation of the movable column part 20 in a state in which the upward rotation limiting member 42 is rotated upward to form a straight line with the fixed column part 10, but the movable column part 20 is the first It should be understood that in the case of being installed at an angle set in the fixed post part 10, it is limited so that the movable post part 20 is no longer rotated upward in a state of being rotated upward at the initially installed angle.

The protective cover 50 is installed to surround the upper outer surface of the fixed column part 10 and the lower outer surface of the movable column part 20, and supports the movable column part 20 to maintain an erected state at a set angle. At the same time, it is formed to prevent the rotational height adjustment unit 30 and the holding rotation limiting unit 40 from being exposed to the outside.

Here, the protective cover 50 may be installed to move in the vertical direction while being formed in the shape of a tubular body having a hollow inside as shown in FIG. 7A and being fitted to the upper outer surface of the fixing column part 10.

At this time, in the fixed support part 10, in order to minimize the vertical movement range of the protective cover 50, the protective cover 50 can be positioned at a height that does not interfere with the downward rotational motion of the movable support part 20. It is preferable to form an outer diameter gradually larger from a point spaced apart from the upper end of (10) by a length corresponding to the height of the protective cover 50 to the bottom surface of the fixing column part 10.

However, in addition to the above-described structure, the protective cover 50 moved downward toward the fixed column part 10 is located on the outer circumferential surface of the fixed column part 10 at a height that does not interfere with the downward rotation of the movable column part 20. A separate support jaw (not shown) may be formed to protrude so that the lower surface of the can be supported.

For reference, the fixed holding part 10 shown in FIGS. 4 to 6B is so that the protective cover 50 is moved downward to a height that does not interfere with the downward rotation of the movable column part 20 as shown in FIG. 7A. It is formed so that the outer diameter of the fixing column 10 gradually becomes larger as it goes downward.

In order to rotate the movable column part 20 downward through this, the upper surface of the protective cover 50 is located on the outer surface of the fixed column part 10 so that the protective cover 50 covers only the outer surface of the fixed column part 10. It is only necessary to move downward toward the fixed column part 10.

In addition, when the movable column part 20 is rotated upward to its original position to maintain an erected state, the upper side of the protective cover 50 may be moved upward so as to surround the lower outer surface of the movable column part 20, and the protective cover ( When 50) is moved upward and the movable column part 20 is maintained in an erect state, the rotational height adjustment part 30 and the column rotation limiting part 40 are not exposed to the outside.

Next, the protective cover 50 may be formed of a plurality of unit covers 51 that are installed in contact with each other along the outer surfaces of the fixed column 10 and the movable column 20 as shown in FIG. 7B. , It is preferable that both side end surfaces of each of the unit covers 51 are provided with coupling means 52 formed to be fitted and coupled in a contact with each other.

Here, the coupling means 52 is a fitting formed to correspond to each other on the side end faces of the unit cover 51 so that both side end faces of the unit cover 51 can be fitted and coupled in contact with each other as shown in the accompanying drawings. It may be composed of a groove (52a) and a fitting protrusion (52b).

In addition, the protective cover 50 is formed so that a plurality of unit covers 51 surround the outer surfaces of the fixed column 10 and the movable column 20, as shown in FIG. 7C, and the plurality of unit covers 51 ) May be formed such that the side end surfaces of the unit covers 51 adjacent to each other rotate around the cover rotation shaft 53 installed in the vertical direction to open or close.

Looking at the effect on the street lamp for a bridge configured as described above is as follows.

A street light 1 equipped with a tilting function according to an embodiment of the present invention rotates the movable post 20 to one side to facilitate the normal operation of the lighting means, the aging state of the street lamp, and the safety inspection of the bridge. It is to be able to adjust the installation height of the street light (1).

At this time, in order to facilitate the vertical rotation of the movable holding part 20, and at the same time, to allow pedestrians and vehicles to safely move under the illumination of the lighting means (L) installed on the upper side of the movable holding part 20 , It is preferable that the length of the fixed column portion 10 and the movable column portion 20 is formed to a length of about 1.5 to 3m, respectively.

Hereinafter, the rotational operation of the movable post part 20 will be described in detail so that the installation height of the street light 1 is adjusted.

First, when it is desired to lower the installation height of the street light (1), a protective cover 50 installed to surround the lower portion of the fixed column portion 10 and the upper portion of the movable column portion 20 is prevented from rotating. It should not be disturbed.

For this purpose, the fixing means 60, which serves to fix the protective cover 50 in close contact with the outer surface of the fixing column 10, is separated, and the upper part of the protective cover 50 is separated from the cover receiving groove 22. It is only necessary to move the protective cover 50 downward by a certain distance toward the fixed column part 10.

After separating the protective cover 50 from the cover receiving groove 22, the upper end of the protective cover 50 is moved downward so that the upper end of the protective cover 50 is positioned on the fixed column 10, or as shown in FIGS. 7B and 7C. Separate it from (10) and the movable holding part (20).

In the case where the protective cover 50 is made as shown in FIG. 7A, it is not necessary to separate the protective cover 50 apart from the fixed holding unit 10, so that loss of the protective cover between operations can be prevented, as well as through a vertical movement method. There is an advantage that it can be quickly and conveniently installed so that the rotational height adjustment unit 30 and the holding rotation limiting unit 40 are not exposed to the outside or, on the contrary, the movable holding unit 20 is rotatably separated.

Thereafter, when part of the fastening force of the fastening shaft 33, which is firmly fastened so that the movable holding part 20 can rotate downward at an appropriate speed, is released, the movable holding part 20 is And since it is in a state capable of rotating in one direction that does not interfere with the movement of the vehicle, the height of the movable column 20 can be quickly and easily lowered to a height suitable for performing a safety check.

At this time, the support bracket 31 and the movable bracket 32 constituting the rotating height adjustment unit 30 are firmly installed on the fixed column 10 and the movable column 20, respectively, and the support bracket 31 and the movable The bracket 32 is installed to rotate in a state in which the support piece 31a and the movable piece 32a are engaged with each other and are in contact with each other, and a fastening shaft 33 that is inserted into the support hole 31b and the movable hole 32b to be fastened. ), as well as the rotation speed and rotation angle are adjusted by the fastening force of the fastening shaft 33, so that the downward rotation operation of the movable column part 20 can be performed stably and smoothly.

In addition, the movable holding unit 20 rotated downward to the set height is supported on the upper surface of the holding rotation limiting unit 40, and more specifically, the downward rotation limiting member 41 constituting the holding rotation limiting unit 40 to rotate downward. As the movable holding unit 20 is kept in a stable state, the movable holding unit 20 is lifted using a lifting tool or a separate support tool to maintain the downwardly rotated state. It is possible to prevent discomfort such as having to support the lower surface of, and a safety accident due to separation of such a lifting tool or a support tool from the movable holding part 20 can be prevented.

In addition, when the movable column part 20 is rotated until the rotation is restricted by the downward rotation limiting member 41 and then the tightening force of the fastening shaft 33 is increased, the support piece 31a and the movable piece 32a are By fixing it in a contacted state, it is possible to more stably maintain the state in which the movable column part 20 is rotated downward.

In this way, when the movable holding part 20 is turned downward to a set height, the operator can safely and quickly perform the safety inspection of the lighting means (L) and streetlights without using a high place work car or ladder. In addition, since the bridge inspection worktable does not interfere with the movement of the working vehicle connected to the outer side of the bridge, the time and manpower required for the inspection work of the bridge can be significantly reduced.

Next, after completing the inspection work of the streetlight (1) and the bridge, if you want to rotate the movable column part 20 upward to the original installation state, the movable column part 20 can be rotated upward at an appropriate speed. Part of the fastening force of the fastening shaft 33 is released so as to be in a state.

Thereafter, when the upper side of the movable column part 20, that is, between the movable bracket 32 and the lighting means (L), is lifted upward, the movable column part 20 is rotated upward around the fastening shaft 33, and is rotated upward. When the angle of the movable post part 20 reaches the original street light (1) shape, the upward rotation limiting member 42 forming the post rotation limiting part 40 is placed on the upper surface of the support bracket 31 and the movable bracket 32 By supporting the lower surface of the movable column 20 is prevented from rotating beyond the set range.

Here, even in the process of upward rotation of the movable column part 20, the support bracket 31 and the movable bracket 32 maintain a surface contact state by being fitted with the support piece 31a and the movable piece 32a. It can be safely and easily rotated upward to the set position.

After the movable column part 20 is rotated upward to be supported by the upward rotation limiting member 42, the support piece 31a and the movable piece 32a are in close contact with each other so that the movable column part 20 rotates arbitrarily up and down. The fastening force of the fastening shaft 33 increases so as not to do so.

After finishing the process of increasing the fastening force of the fastening shaft 33, the upper outer surface of the fixed post part 10 and the lower outer surface of the movable post part 20 are wrapped around the rotational height adjustment part 30 and the post rotation limiting part ( It is sufficient to perform the work of installing the protective cover 50 so that 40) is not exposed to the outside.

At this time, when the protective cover 50 is fitted to the outer surface of the fixed column 10 and installed so as to be moved up and down as shown in FIG. 7A, the upper part of the protective cover 50 is inserted into the cover receiving groove 22 to be accommodated. If it is made to move upward to the (20) side, and is made of a unit cover 51 as shown in Figs. 7b and 7c so that it can be separated and coupled, after wrapping the upper outer surface of the fixed column part 10 and the lower outer surface of the movable column part 20 The upper part of the protective cover 50 may be moved upward toward the movable column part 20 so that the upper part of the protective cover 50 is inserted into and received in the cover receiving groove 22.

After the upper part of the protective cover 50 is installed to be fitted and received in the cover receiving groove 22, the protective cover 50 is fixed in close contact with the outer surface of the fixing column part 10 using the fixing means 60. It is only necessary to be firmly coupled to the coupling force holding member 15 installed on the inner surface of the fixing column 10.

In this way, in a state in which the movable column part 20 is restricted so that it is no longer rotated upward by the upward rotation limiting member 42, the fastening force of the fastening shaft 33 can be increased to maintain the movable column part 20 in an erect state. In addition, since the protective cover 50 limits the rotation of the movable holding unit 20, the movable holding unit 20 can be maintained in a stable erected state.

In addition, the protective cover 50 covered by the rainwater inflow prevention port 21 prevents rain or snow from entering the rotational height adjustment unit 30 and the support rotation limiting unit 40, thereby preventing corrosion. It can prevent deformation or malfunction caused by.

In addition, the protective cover 50 serves to protect from external direct and indirect impacts by blocking the rotational height adjustment unit 30 and the post rotation limiting unit 40 from being exposed to the outside, thereby providing a tilting function. Not only can the durability of the street light 1 be increased so that the service life can be increased, but it is easy and simple to install and remove, thereby increasing the efficiency of management and maintenance.

On the other hand, as the fixing means 60 for maintaining the protective cover 50 installed on the street light 1 is installed to be exposed to the outside, it is inevitable to be vulnerable to corrosion by snow or rain. To prevent this, the fixing means For (60), it is preferable to use the anti-rust treatment.

However, even if the fixing means 60 is subjected to rust prevention treatment, considering that the rust prevention effect decreases after a certain period of time, as shown in FIG. 8A, the head of the fixing means 60 is in direct contact with snow or rainwater. It is provided with an accommodating portion 55 formed so that the head portion of the fixing means 60 can be accommodated in the protective cover 50 as shown in FIG. 8B or installed to protrude a certain length of the blocking piece 54, which can be prevented, The receiving portion 55 is installed so that the head of the fixing means 60 is wrapped by a protective cap 56 made of a resin material, so that the fixing means 60 is more effectively prevented from being corroded.

As described above, in the street light 1 equipped with a tilting function according to the present invention, the movable post part 20 is rotated downward to one side, so that the height of the street light 1 is quickly and stably lowered to a height that is easy for inspection work. Of course, as the downwardly rotated state of the movable holding part 20 is stably maintained, the inspection work of the street light 1 and the bridge can be performed quickly and smoothly in a safe environment. There is an effect of providing a smooth traffic environment by not obstructing the passage of vehicles.

In addition, when the movable column part 20 is erected to provide lighting to the sidewalks and lanes, the rotational height adjustment unit 30 and the column rotation limiting unit 40 are prevented from being exposed to the outside and at the same time prevent the inflow of snow or rainwater. It can be prevented and safely protected from the risk of deformation or damage caused by external shocks, so not only can the overall service life of the street light 1 be increased by increasing the durability of the street light, but also the efficiency of management and maintenance can be increased. It works.
