Description

A water drill drilling support for road and bridge crash wall

Technical Field

The utility model relates to the technical field of road and bridge construction, in particular to a water drill hole support for a road and bridge anti-collision wall.

Background Art

In road and bridge construction, especially in the construction of high-speed railways across densely populated areas, in order to avoid noise disturbance caused by the passage of passenger cars, it is often necessary to install sound barriers on the curbs on both sides of the bridge. The wind force when the passenger car passes at high speed impacts the sound barrier, and the sound barrier columns gradually begin to shake, thus posing a huge safety hazard. In order to eliminate such safety hazards, the sound barrier columns must be reinforced. The existing reinforcement method is usually to drill holes in the crash wall to install steel plates, and use I-beams to weld the sound barrier columns to the steel plates on the crash wall, so that the sound barrier columns and the crash wall form a whole, completely solving the problem of sound barrier column shaking.

Workers generally use water drills to drill holes on the side of the crash wall. Currently, there are two types of water drills: the first is a purely manually operated drilling machine (such as the patent with application number CN202021894726.1), and the second is a drilling machine with a feed bracket (such as the patent with application number CN202120527409.4). For the first type of drilling machine, it is very laborious for workers to operate. For the second type of drilling machine, although it is convenient for drilling control, the feed bracket needs to be fixed to the crash wall with expansion bolts. Due to the large number of drilling positions, it is very troublesome for on-site workers to repeatedly install expansion bolts and feed brackets.

DETAILED DESCRIPTION

In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

As shown in FIG1 , the present embodiment discloses a water drill drilling support for a road and bridge crash barrier, comprising a wall connection frame 1 and a water drill placement frame 4. The wall connection frame 1 comprises a top frame 101, and a first door frame 102 and a second door frame 103 are welded on both sides of the top frame 101, and both sides of the first door frame 102 are provided with lifting mechanisms 2, and the tops of the two lifting mechanisms 2 are both connected to the driving device 3 by power; the driving device 3 drives the two lifting mechanisms 2 to move up and down at the same time, thereby adjusting the height of the water drill placement frame 4.

The diamond placement frame 4 includes a bottom bracket 401 , and two vertically arranged columns 402 are welded to one side of the bottom bracket 401 . The columns 402 are detachably connected to the corresponding lifting mechanisms 2 .

In this embodiment, the lifting mechanism 2 includes a guide groove 201 vertically arranged on the side of the first portal frame 102, the opening direction of the guide groove 201 is away from the second portal frame 103, a slide 202 is arranged in the guide groove 201, a screw rod 203 is threadedly connected to the slide 202, and the end of the screw rod 203 is rotatably connected to the first portal frame 102.

The slide 202 is detachably connected to the column 402. Specifically, two first studs 202-1 are welded on the slide 202, and two mounting holes 402-1 are provided on the column 402 to be plugged into and matched with the first studs 202-1. After the first studs 202-1 are inserted into the mounting holes 402-1 and threadedly connected with nuts, the diamond placement rack 4 can be fixed on the slide 202.

The tops of the two screw rods 203 are connected to the driving device 3, which includes a driving shaft 301, which is rotatably connected to the top frame 101, a handwheel 302 is provided at one end of the driving shaft 301, and two worm gears 303 are provided on the driving shaft 301, one side of the worm gear 303 is meshed with a turbine 304, and the turbine 304 is fixed to the top of the screw rod 203.

In this embodiment, a protective cover 5 is provided above the driving device 3 , and the protective cover 5 is fixed on the top frame 101 .

In this embodiment, the lower ends of both sides of the second door frame 103 are threadedly connected with second studs 6, the second studs 6 face the first door frame 102, and the second studs 6 are provided with legs 601 at one end close to the first door frame 102, and locking nuts 602 are provided on the second studs 6. In order to improve the anti-slip property of the legs 601, anti-slip rubber pads 603 are provided on the legs 601.

As shown in Figure 2, the use process of the utility model is as follows:

First, assemble the wall connection frame 1 and the water drill placement frame 4 together, and then place the wall connection frame 1 on the crash wall 7, wherein the first door frame 102 is located on the inclined side of the crash wall 7, and the second door frame 103 is located on the straight side of the crash wall 7 (because the cable trough and cover plate have been installed on the vertical side of the crash wall, the operating space is too small and it is not easy to construct. Therefore, after the first door frame 102 is arranged on the inclined side of the crash wall 7, it is convenient to leave space to arrange the water drill rig 8 and the water drill placement frame 4). Adjust the extension length of the second stud 6 so that the support leg 601 is stably against the crash wall 7. After the wall connection frame 1 is fixed and stable, the feed bracket of the water drill rig 8 is installed and fixed on the bottom bracket 401, and the bottom bracket 401 is reserved with a mounting hole connected to the feed bracket. The worm 303 and the turbine 304 are driven by rotating the hand wheel 302 to make the screw rod 203 rotate to raise or lower the height of the water drill mounting frame 4. After the drilling position is determined, the water drill rig 8 can be started to perform the drilling operation.

After the drilling is completed, it is only necessary to lift the entire drilling support upwards and then carry the drilling support along the direction of the anti-collision wall 7. The water drill 8 in this embodiment adopts the second structural form in the background technology, which belongs to the prior art, and those skilled in the art can obtain existing products from the market.

The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
