Technical Field

[0001] The present application belongs to the technical field of guardrail construction, and specifically relates to a horizontal hole opening auxiliary device suitable for anti-collision guardrail operations. Background Art

[0002] When constructing bridge and road crash barriers, it is necessary to use a water drill to drill holes on the side of the crash barrier to facilitate the subsequent installation of the crash barrier. In order to control costs during construction, single or multiple water drills are often used to drill holes. One machine can be used for multiple purposes, and water drills are used for horizontal and vertical drilling operations.

[0003] Due to the functional limitations of the drilling machine, the drilling machine can only drill from top to bottom or from one side of the plane to the other side. However, during the drilling operation, the water from the water drill will flow out sewage downward from the working surface, and the flatness of the holes cannot be guaranteed. In order to control the flatness of the overall working surface and facilitate the subsequent anti-collision guardrail installation project, secondary drilling and leveling construction is required, resulting in repeated construction, high fuel consumption of the machinery, and extremely low construction efficiency. Utility Model Content

[0008] Furthermore, the left leg and the right leg are both slidably connected to the bracket along the lateral direction of the bracket.

[0009] Furthermore, the left leg and the right leg are both hinged to the bracket along the longitudinal axis.

[0010] Furthermore, the left leg and the right leg are arranged symmetrically.

[0011] Furthermore, four horizontal holes are provided on the left leg and the right leg.

[0012] Furthermore, the four horizontal boreholes are arranged in a rectangular shape.

[0013] Furthermore, a level ruler is provided on the bracket.

[0014] Furthermore, the level is glued to the bracket.

[0015] Furthermore, the bracket is provided with a transverse groove, and the level is located in the transverse groove.

[0016] Beneficial effects of this application:

[0017] 1. Simple installation and easy disassembly. The device can be quickly installed and leveled. The legs and the fine steel bracket are connected as a whole. The installation and disassembly process is simple and convenient, and rapid installation and disassembly on site can be achieved.

[0018] 2. Large working area and high construction efficiency. The working range of this device is several times that of ordinary drilling machines, and it can achieve rapid leveling and leveling operations with high construction efficiency.

[0019] 3. The construction quality is reliable and the working surface is flat. The overall flatness is adjusted using a level ruler, so that there will be no problems such as tilting during drilling operations, avoiding secondary leveling and rework due to hole tilt.

[0025] The present application is further described below in conjunction with specific embodiments and drawings.

[0026] refer to Figure 1 and Figure 2 As shown, a horizontal hole opening auxiliary device includes a left leg 1, a right leg 2, a bracket 3, a horizontal drilling hole 4, a guardrail 5, a guardrail fitting slope 6 and a level ruler 8.

[0027] A bracket 3 is connected between the upper end of the left leg 1 and the upper end of the right leg 2. The bracket 3 adopts a horizontal rod structure. The bracket 3 connects the left and right legs into a whole, so that the device forms a stable structure that can stably act on the guardrail 5.

[0028] The left leg 1 and the right leg 2 are both inverted cone structures, and the inner sides of the left leg 1 and the right leg 2 are both guardrail fitting inclined surfaces 6, ensuring that the left and right legs are stably fitted on the left and right sides of the guardrail 5. Horizontal drill holes 4 are provided on the left leg 1 and the right leg 2, and the horizontal drill holes 4 on the left leg 1 and the right leg 2 are arranged relatively to each other on the left and right sides. The horizontal drill holes 4 are used to guide the drill rod of the drilling rig to ensure the flatness of the drill hole.

[0029] The left leg 1 and the right leg 2 are both fixedly connected to the bracket 3. The legs and the bracket can be directly welded or fixedly connected by bolts. The device formed in this form is a fixed whole and cannot be adjusted for different guardrails 5. The advantage is that it is easy to manufacture and is reliable as a whole.

[0030] Alternatively, the left leg 1 and the right leg 2 are both slidably connected to the bracket 3 in the transverse direction of the bracket 3, and the left and right legs can be adjusted in transverse position to change the left and right spans and be placed on guardrails 5 of different widths. Specifically, a transverse slide groove can be opened on the bracket 3, and then the slider of the leg can be slidably matched in the transverse slide groove, and after being adjusted in place, the slider can be tightened with a screw to achieve locking.

[0031] Alternatively, the left leg 1 and the right leg 2 are both hinged to the bracket 3 along the longitudinal axis, so that the left and right legs can rotate and swing to adjust the inclination angle of the guardrail to the inclined surface 6 and adapt to the inclination of the inclined surfaces of different guardrails 5. The legs are hinged to the bracket through a hinge shaft, and the axis of the hinge shaft is arranged along the longitudinal direction. After rotating into place, the legs can be tightened with screws to achieve locking.

[0032] In addition, the lateral adjustment and rotational adjustment of the left leg 1 and the right leg 2 can be combined into one, so as to simultaneously meet the adaptation of guardrails 5 of different widths and slopes. Specifically, the leg can be divided into an upper and lower part, the upper part forms a sliding connection with the bracket in the lateral direction, and the lower part forms a hinged connection with the upper part along the longitudinal axis, and a guardrail fitting inclined surface 6 and a horizontal drill hole 4 are arranged on the lower part.

[0033] The left leg 1 and the right leg 2 are arranged symmetrically to meet the symmetrical structure of the conventional guardrail 5. Four horizontal holes 4 are provided on the left leg 1 and the right leg 2, and the four horizontal holes 4 are arranged in a rectangular shape to meet the requirements of four rectangular horizontal holes required for construction.

[0034] A level ruler 8 is provided on the bracket 3, and the level ruler 8 is placed on the bracket 3 for judging the levelness of the entire device to avoid the presence of debris or uneven guardrails between the legs and the guardrails 5 when they are fitted together, causing the entire device to be uneven and affecting the levelness of the horizontal drilling 4.

[0035] The level ruler 8 is glued to the bracket 3. When in use, the level ruler 8 is glued to the bracket 3. When not in use, the level ruler 8 is removed and used for other purposes. The bracket 3 is provided with a transverse groove, and the level ruler 8 is located in the transverse groove. The transverse groove facilitates the placement of the level ruler 8. The level ruler 8 is fixed in the transverse groove, and the level ruler 8 reflects the levelness of the entire device.

[0036] The workflow of this application is: fit the left and right legs onto the left and right sides of the guardrail, then place the bracket across the guardrail, use a spirit level to determine the levelness of the overall placement, and once the requirements are met, start the water drilling rig fixed on the guardrail to operate, insert the drill rod of the drilling rig into the horizontal drill hole for drilling operations, use the horizontal drill holes relative to each other on both sides to intuitively determine the flatness of the drill holes, and perform adjustments and operations directly on site without the need for secondary rework.

[0037] The aforementioned basic examples and their further selected examples can be freely combined to form multiple embodiments, all of which are embodiments that can be adopted and claimed for protection in this application. In the scheme of this application, each selected example can be arbitrarily combined with any other basic examples and selected examples.
