The present invention relates to a street lamp, and in particular, the winding device for elevating the lamp housing of the street lamp is improved, so that the safety-type winding device is provided to prevent the lamp and the lamp housing from falling apart due to the user's peripheral or malfunction It's about streetlights.

As is well known, a plurality of street lamps are installed on a road or a residential street to secure a view of a driver driving a vehicle, and street lamps that are lit from sunset to sunrise are installed.

The street lamp is a mercury lamp, sodium lamp is selected to be suitable for the road situation to install a lamp on the front end of the lamp post, and the lamp housing is coupled to protect the installation state of the lamp. If the street lamp is used for a long time, it will be unable to maintain its lit state due to the long life of the lamp. Therefore, the lamp should be replaced after a long period of time after the installation of the street lamp. Therefore, it needs to be cleaned, but since the height of the lamppost is very high, the lamp replacement work was carried out while the worker got on the elevated vehicle with the bucket installed.

However, the lamp replacement work using high-priced vehicles has to be carried out in a state in which the high-speed vehicle is stopped, so there is a problem in that the operation of the vehicle is disturbed as the work proceeds under the control of the lanes of the roads. In order to replace the lamp by lowering only the lamp housing of the street lamp has been applied for a number of utility models, a typical example is the Republic of Korea Utility Model Application No. 2003-37625 (designation name: street lamp with removable lift lamps, hereinafter ' Citations').

1 to 3 is installed in the cable roller winch 100 winding the cable 101 consisting of a rope and a wire integrally under the street lamp as shown in Figure 3, and fixedly installed on the street lamp 102, the cable 101 A pillar roller (103) for guiding the movement is installed, and a rotary joint (105) pivoted to support a state in which the lamp (104) is installed to protrude in one direction is installed at the lower portion of the pillar roller (103). The light box 107 is installed at the tip of the horizontal column 106, which is integrally coupled to the rotary joint 105, and the lamp 101 is installed, and the cable 101 wound around the cable roller winch 100 is pillar-roller. Connect to the light box (107) via (103).

In addition, the cable roller winch 100 has a cable fixing roller 108 for fixing one end of the cable 101 on one side thereof, the guide 109 is installed on both sides is moved according to the operation of the winch handle 110 A moving roller 111 is installed, and a plurality of moving rollers 112 through which the cable 101 passes is installed on both sides of the moving roller 111, and a moving roller (outside the moving roller 111). The fixing roller 113 through which the cable 101 passes 112 is installed, but the cable 101 passes through the moving roller 112 and the fixing roller 113 sequentially.

Such a reference design is that when the moving roller 111 moves along the guide bar 109 according to the operation of the winch handle 110, the moving roller 112 installed thereon is moved together so that the moving roller 112 and the fixed roller are moved. A change in length occurs in the cable 101 passing through the 113, so that the length of the cable 101 increases or decreases, and when the length of the cable 101 increases, the tension applied to the light box 107 from the fixed roller 113. As it is released, the transverse holder 106 falls about the rotary joint 105.

The cable connected to the light box 107 coupled to the cross holder 106 as the length of the cable 101 continues to increase while the cross holder 106 is rotated and the light box 107 is rotated downward. 101) descends.

In addition, when the light box 107 reaches the position where the lamp 104 can be replaced, the operation of the winch handle 110 is stopped, the lamp 104 installed in the light box 107 is replaced, and the winch handle 110 again. ), The light box 107 is raised as the cable 101 is pulled, and the light box 107 is coupled to the cross holder 106 and rotates when the cable 101 is continuously pulled. When the horizontal column 106 is rotated around the joint 105 in a rising direction, the operation of the winch handle 110 is stopped when the horizontal column 106 is rotated.

However, since the lifting device according to the prior art does not have a separate device for controlling the rotational movement of the roller, when the lamp housing is lowered from the street lamp, the lamp housing is damaged due to a sudden fall by the worker's sub-circumference and the lamp housing is damaged or the worker is injured. There is a problem that can wear.

The present invention is devised to improve the above problems of the prior art, to prevent the rotation in the state in which the lamp housing is seated, and to prevent the safety accident by preventing the rotation speed to rise above a predetermined value when lowering the lamp housing. It is an object of the present invention to provide a street lamp provided with a safety winding device.

A locking means (70) for separating from the roller (50), a speed preventing means (80) installed between the roller (50) and the stopper (60) to prevent the rotational speed of the roller (50) from rising by more than a predetermined value; It is provided between the main body 40 and the roller 50 comprises a restraining means 90 to suppress the rotation of the roller 50.

As a result, when the operator opens the cover 12 of the support 11 and dismantles the restraining means 90, and then rotates by connecting the power tool D to the roller 50, the rope 15 is wound from the roller 50. Or the lamp housing 35 installed on the upper end of the support 11 is lowered or raised to perform repair, replacement and cleaning of the lamp installed inside the lamp housing 35.

At this time, since the speed of the roller 50 is prevented from rising above a predetermined value by the speed preventing means 80, the lamp housing 35 descends or rises at a safe low speed, and thus falls off the ground or collides with an operator. You can prevent accidents.

Here, the main body 40 is the front panel 42 and the rear panel 44 is formed at a predetermined interval, the roller 50 and the locking means 70 is installed on the front panel 42 and the rear panel 44. As the hole portions 42a and 44a are formed, the roller 50 is rotatably installed in the hole portion 42a of the front panel 42, and the restraining means 90 is installed at the upper end of the front panel 42. The stopper 60 is slidably installed in the hole 44a of the rear panel 44.

Since the hole portion 44a of the rear panel 44 is formed with a straight section on one side as shown in FIG. 6, the stopper 60 may be inserted to be slidably while preventing the stopper 60 from rotating.

In addition, the roller 50 includes a winding portion 52 on which the rope 15 is wound, a first panel 54 and a second guide 56 formed of circular panels and installed at both ends of the winding portion 52. And a rotating shaft 58 protruding from the first guide 54 and inserted into the hole 42a of the front panel 42 and coupled with the power tool.

Here, the through shaft portion 58a formed in communication with the second guide 56 from the end of the rotation shaft 58 so that the stopper 60 is slidably inserted into the rotation shaft 58, and the outer end circumferential surface of the rotation shaft 58. The fastening part 58b which is processed into this polygon and into which a power tool is inserted is formed.

As a result, a polygonal groove portion into which the fastening portion 58b is inserted is formed at the end connected to the power tool D, that is, the rotating shaft 58, as shown in FIG. 5, and a circular shape inserted into the through hole portion 58a. When the power tool formed in the center of the shaft (B) is inserted into the rotary shaft (58), the circular shaft (B) is separated from the locking groove (72) by inserting the insertion protrusion (74) of the locking means (70), which will be described later. ) Is switched to the rotatable state.

In addition, the stopper 60 includes a through shaft 62 slidably inserted into the through hole portion 58a, and a control panel 64 provided at an inner end of the through shaft 62 to correspond to the outer wall of the second guide 56.

As a result, when the roller 50 is rotated, as shown in FIG. 9, the flow piece 84 installed on one side of the second guide 56 is rotated to slide along the circumferential surface of the control panel 64, and the roller 50 is rotated. When the stable rotation is performed at a predetermined speed or less, the flow piece 84 passing through the locking jaw portion 82 is rotated along the central axis 84a, so that the end portion farther from the locking jaw portion 82 is heavier. Since the 84a is eccentric, the end of the heavy side is moved downward and the end of the side closer to the locking jaw 82 is lifted, so that the flow piece 84 is not caught by the locking jaw 82 and continues on the circumferential surface of the control panel. It is rotated along with the roller 50 while sliding along.

At this time, when the roller 50 is accelerated by a predetermined speed or more, the flow piece 84 passing through the locking jaw portion 82 rotates about the central axis 84a and corresponds to the locking jaw portion 82 again before the end is lifted. Since the fluid piece 84 is caught by the locking projection 82 as shown in FIG. 9, the fluid piece 84 and the roller 50 can no longer be rotated.

Such a configuration and operation can prevent the roller 40 from rotating above a predetermined speed, thereby preventing the lamp housing 35 from being accelerated and falling to the ground.

In addition, the restraining means 90 is a plurality of grooves formed while maintaining a predetermined interval on the outer end of the first guide 54, 'b' shape is bent to be rotatably installed on the front panel 42 The site includes a support 94 inserted into the groove 92.

Thus, the user opens the cover 12 of the support 11 and then rotates the support 94 to release the support 94 from the groove portion 92 of the first guide 11 and then the roller 50 of the roller 50. The rotation of the roller 50 may be achieved by inserting the power tool D into the rotation shaft 58.

Subsequently, when the work is completed, the support 94 is rotated downward to rest the support 94 in the groove 92 of the first guide 54, thereby inhibiting rotation of the roller 50. A double stabilizer can be achieved by the means 90 and the locking means 70.
