Description

A median strip and guide rail sweeper

The present invention relates to a cleaning device for cleaning the central separator and the guide rail of the road by using a rotary brush mounted on the multi-purpose vehicle, and more specifically, it is possible to vertically transfer the rotary brush as well as symmetric in the vertical direction. It can be rotated and transported to provide a wide working area and convenience of work, and the rotating brush can be rotated about the Y axis alone in a horizontal or vertical state to clean a wider area and various objects. It relates to a median separator and guide rail cleaning device.

In general, in order to clean the running vehicle, the median separator and guide rails installed in the center of the road and the side of the road can be cleaned by installing a high pressure jet sprayer that sprays water stored in the water tank at high pressure. At the same time it was cleaning by spraying high pressure water. However, according to the conventional method, only the side surfaces are intensively cleaned, so that foreign substances or contaminants stuck to the upper part cannot be cleaned cleanly.

In addition, since such cleaning work is dependent on manpower, the work efficiency decreases and there is a high risk of safety accidents, and a lot of work time takes economical deterioration and causes serious traffic jams.

As a way to solve this problem, `` Patent Application No. 2002-0023068 No. Central Separation or Pan Cleaning Device '' was proposed.

Thus, when looking at the invention of the first application, the invention of the first application is equipped with a cleaning device having a mechanical structure capable of moving the rotary brush member and the third frame, which is coupled to the brush member up, down, left, right. Thus, it was possible to remove foreign substances adhering to the left and right sides or the upper surface of the roadway median, pans, and barriers.

However, the above-described prior invention has the following improvements despite solving the conventional problems.

First, there is no dedicated vertical transfer means for vertically moving the rotary brush in a state close to the object to be cleaned without flow in all directions, thereby increasing the inconvenience of vertical transfer and additional vehicle position change.

In other words, once the hydraulic cylinder is operated to raise and lower the rotating brush, the rotating brush can be raised and lowered once, but the first frame and the rotating brush are simultaneously removed from the object to be cleaned according to the rotation radius of the rotating two links. Being far away or closely adhered to, the worker is inconvenient in the task of having to move the vehicle to a proper position again for a smooth cleaning operation.

Second, since the vertical conveyance is limited to the operation of the hydraulic cylinder, the vertical cleaning area is very narrow, so it is limited to the object to be cleaned such as the center separator and guide rail, but the height of the object is relatively high. The work was impossible.

Third, while the rotating brush can be rotated to be positioned horizontally or vertically according to the purpose of use, the rotating brush positioned in the horizontal or vertical state cannot be rotated at various angles about the Y axis, and thus the cleaning area and the object are very large. It was limited.

Fourth, when the horizontal movement of the rotating brush is carried horizontally by a pair of guide members having a pipe form, the transfer operation was not smooth.

Fifth, the safety device is not provided in the lifting device which basically lifts the cleaning device including the rotating brush, and when the lift cylinder is subjected to excessive load, the rotating brush falls to the lower part and may be damaged, as well as personal injury. Was.

The present invention is to improve the problems caused by the above-described prior invention, using a vertical transfer cylinder to transfer the rotating brush in the vertical direction without flow in all directions, as well as rotating the rotating brush to be symmetric in the vertical direction of the vertical direction The invention seeks to secure a wide working area and to provide convenience for the work, and to rotate a rotating brush positioned horizontally or vertically at various angles about the Y axis to clean a wider area and objects to be cleaned. It is for the best purpose.

In addition, the horizontal movement of the rotating brush is made by a guide roller for smoothly transporting on the conveyance rail to make the rotation brush more smoothly horizontal transfer is another object.

In addition, by installing a safety device in the lift cylinder for lifting the cleaning device including a rotating brush to another object to prevent the safety accident due to the damage of the lift cylinder.

Brush vertical transfer means 30 for vertically transferring the rotary brush 60 by vertically transferring 32, and a brush Y installed at the upper end of the transfer inner tube 32 to rotate the rotary brush 60 about the Y axis. Axial rotation means 40, the brush X-axis rotation means 50 is installed on one side of the horizontal rotating body 49 to rotate the rotating brush 60 around the X-axis, and the brush X-axis rotation means 50 It can be seen that the rotation brush 60 is coupled to the tip of the second horizontal stage 63 of the.

It will be described in more detail to enable the present invention made of the above schematic configuration.

The main frame 10 of the present invention serves to guide and support the transport at the time of the left and right horizontal transfer of the rotary brush 60, a pair of transport rails 11 are spaced apart by a predetermined distance up and down It is installed and both ends of the conveying rail 11 is connected and finished by the end plate 12, the conveying rail 11 is welded integrally to the main bracket (8).

At this time, the conveying rail 11 is in the form of a conventional square tube, but is preferably arranged in a lozenge so that the guide roller 23 is coupled to the upper, lower surfaces by 45 degrees to be guided conveyed. Therefore, the guide roller 23 can be smoothly transported on the conveying rail 11, so that the horizontal conveying operation of the rotating brush 60 becomes smoother.

The transport housing 20 for horizontally transporting the transport rails 11 selectively has a quadrangular shape, but the bottom end forms an annular fixing plate 21 and upper and lower sides of the rear plate 22. A pair of guide rollers 23 coupled to the upper and lower portions of the conveying rail 11 and guided along the upper and lower surfaces are respectively installed, and the fixed bracket 25 integrally attached to the front plate 24 is conveyed. A transfer motor 26 generating power for horizontally moving the housing 20 is installed.

The pinion gear 28 is connected to the transfer motor 26 by the transfer motor 26 by integrally coupling the pinion gear 28 to be engaged with the rack 27 integrally attached to the front surface of the upper transfer rail 11. As the drive in the horizontal direction by riding the rack 27, the transport housing 20 is capable of horizontal transfer by receiving a horizontal transfer force.

The support roller 23a is rotated at the bottom of the transport housing 20 to prevent the transport housing 20 from falling down due to the gravity of the rotary brush 60 located at the front side during the transport process of the transport housing 20. It is possible to install, the support roller (23a) is coupled to be in close contact with the lower portion of the conveying rail 11 can be smoothly transported on the front portion of the conveying rail 11 while maintaining a stable support state.

In addition, the first horizontal stage 29 is rotatably coupled to the hinge shaft 29-1 at the front end of the transfer housing 20 to rotate the rotating brush 60 in the horizontal direction, and the rotational position is When set, as shown in FIG. 7, the fixing hole of any one of the plurality of fixing holes 29-3 radially formed in the fixing plate 21 while penetrating the first horizontal stand 29 using the fixing unit 29-2 ( 29-3) can be maintained in a fixed state.

In the brush vertical transfer means 30 for vertically transferring the rotary brush 60 alone, a vertical stand 31 is installed at one end of the first horizontal stand 29, and a roller is formed inside the vertical stand 31. The conveying inner tube 32 which is free to move up and down is installed by a rotational support such as the upper and lower conveying inner tube 32, which is connected to the first horizontal stage 29 and the vertical conveying cylinder 33, It is possible to transfer the rotary brush 60 in a vertical state without flowing in all directions while vertically moving according to the stretching operation.

In other words, by operating the dedicated vertical transfer cylinder 33 without using the lifting device 1 to transfer the rotary brush 60 in the vertical direction close to the object to be cleaned up and down by the lifting device 1 When working, there is no fear that the rotational brush 60 may move away from the object to be cleaned or too close, thereby providing convenience in operation. At the same time, the conveying width in the vertical direction is widened, so that it is possible to clean a wide range of areas and objects such as tunnels or soundproof walls having a relatively high cleaning position, as well as a central separator and a guide rail of a road.

The Y-axis rotating means 40 installed at the upper end of the conveying inner tube 32 to secure a wider working area by rotating the rotating brush 60 by a predetermined angle around the Y axis as shown in FIG. The separation prevention jaw 42 formed in the fixing flange 41 is inserted into the upper end of the) and then fixed integrally through the welding operation, and the rotating support 44 formed on the rotating flange 43 is rotatable to the fixing flange 41. The fittings are combined.

At this time, the rotation flange 43 is caught through the release prevention plate 45 through the release prevention plate 45 through the opening portion (32a) formed on one side of the inner tube 32 to prevent the departure from the fixed flange (41). By screwing the bolt 46 to the rotary support 44 in a state, the rotation flange 43 can be prevented from being separated and can be selectively rotated by a predetermined angle, so that the rotary brush 60 can be rotated by a predetermined angle to make it wider. You will have a working area.

In addition, the rotating flange 43 is a fixing hole of any one of a plurality of fixing holes (48) formed radially in the fixing flange 41 in the state that is penetrated by the fixing member 47 as shown in FIG. 48, it is possible to maintain a fixed state, and the upper side of the rotating flange 43 is a horizontal rotating body 49, which is a medium for installing the rotating brush 60 in the horizontal direction is integrally formed.

On the other hand, the fixed flange 51 is integrally attached to the front end of the horizontal pivot 49 to selectively rotate the rotating brush 60 about the X axis to be positioned horizontally or vertically, at any angle X brush Rotating means (50) after the separation prevention jaw 52 formed in the rotation flange 53 is fitted to the second horizontal stage 63 attached to the side of the upper end of the brush mounting unit 61 via the reinforcement plate 62 It is fixed integrally by the welding operation and the rotation support portion 53 is rotatably fitted to the rotary flange (53) formed on the fixed flange (51).

At this time, the fixing flange 51 is a departure prevention plate 55 through the opening preventing portion (63a) formed on one side of the second horizontal stage 63 to prevent the departure from the rotating flange (53). By being screwed to the rotary support 54 with the bolt 56 in a locked state, the fixing flange 51 can be prevented from being detached and can be selectively rotated by a predetermined angle so that the rotary brush 60 can be rotated exclusively about the X axis. Or rotate vertically or by an arbitrary angle to secure a wider working area.

That is, the rotating brush 60 may be positioned in a horizontal state to clean the upper surfaces of the center separator and the guide rail, and the rotating brush 60 may be vertically positioned to intensively clean the side of the object to be cleaned.

In addition, the fixing flange 51 is a fixing hole of any one of a plurality of fixing holes 58 formed radially in the rotating flange 53 in the state in which the fixing device 57 is penetrated by the fixing device 57 as shown in FIG. 58) to be fixed.

On the other hand, the rotary brush 60 is rotatably mounted to the brush mounting base 61 is not normally connected to the central portion to the second horizontal stage 63 of the second horizontal stage 63 in the present invention as shown in FIG. The upper end of the brush mounting base 61 is coupled to the front end to be integrally eccentric.

Here, the reason why the upper side is eccentrically connected is to operate the vertical transfer cylinder 33 to vertically lift the rotary brush 60 first, and then perform a high height operation during the operation of the vertical transfer cylinder. Even when the expansion limit point of (33) is reached, the rotary brush 60 is positioned higher when the rotary brush 60 is rotated 180 degrees so as to be vertically symmetrical as shown in FIG. 14 using the brush X-axis rotating means 50. Of course, it provides an effect that can clean the tunnel or the soundproof wall of higher positions.

When the lift cylinder 6 is damaged during the cleaning operation, the present invention combines the lift cylinder 6 as shown in FIG. 11 to prevent the rotating brush 60 from being damaged while the lift frame 7 is struck downward. Locking ring 72 is installed on each of the fixed bracket (5) and the cylinder bracket (71) installed on the lift frame (7), the lock connected to the safety chain (73) coupled to any one of the fixed ring (72) It is possible to maintain safety by hanging 74 on the other fixing ring 72.

An operating state of the present invention having such a configuration will be described.

When the transfer motor 26 is first operated, the transfer housing 20 is smoothly transferred on the transfer rail 11 by the combination of the pinion gear 28 and the rack 27, and the worker moves to the place where the object to be cleaned is located. After the rotating brush 60 is transferred, the first horizontal stage 29 is first rotated to maintain the state close to the object to be cleaned.

In this case, when the side cleaning operation is required, it is possible to use the rotating brush 60 in the vertical state by using the brush X-axis rotating means 50 as shown in FIG. 12, and to move the rotating brush 60 in the vertical direction during the operation. In this case, it is possible to transfer the rotary brush 60 in the vertical direction without flowing in all directions by operating the dedicated vertical transfer cylinder 33 without using the lifting device 1 as in the prior art. This eliminates the conventional problem of changing the position of the rotating brush 60 by moving the vehicle 2 again because the rotary brush 60 does not move away from the object to be cleaned or excessively close during the vertical transfer. .

In addition, when the rotary brush 60 is moved to a higher position to carry out the height work, the rotary brush 60 is rotated 180 degrees so as to be symmetric in the vertical direction as shown in FIG. ) To provide a variety of work functions that can be carried out separately.

And, when cleaning the upper surface, as shown in Figure 13 by using the brush X-axis rotation means 50 to position the rotating brush 60 in a horizontal state it is possible to clean the upper surface neatly.

Meanwhile, the present invention uses the Y-axis rotating means 40 in a state where the first horizontal stand 29 is not operated to rotate the rotary brush 60 at various angles as shown in FIGS. 15 to 16 to maximize the object to be cleaned. It can be cleaned neatly in close proximity.

The X, Y-axis rotation means 50, 40 is not limited to the rotation angle shown in the drawings, but in a state that is as close as possible to the object to be cleaned in a simple manner by adjusting the angle range in more various ways depending on the purpose of use and the purpose of use. Cleaning can be done conveniently.

The present invention by using a brush vertical transfer means to transfer the rotary brush in the vertical direction without flow in all directions, as well as to rotate the rotary brush to be symmetrical in the vertical direction to secure a wider working area in the vertical direction to the center separator of the road and The guide rail as well as the height of the object such as tunnels, soundproof walls, etc. while providing the convenience of work.

In addition, it is possible to clean various areas and objects by rotating the rotating brush located in a horizontal or vertical state to have a variety of angles around the Y-axis to position the rotating brush as close as possible to the object to be cleaned.

In addition, even if the lifting cylinder is damaged by the safety device installed on the lifting cylinder, the safety of the work is guaranteed, as well as the rotating brush provides the effect of smoothly moving the guide roller installed in the transport housing by smoothly moving on the transport rail.
