[0033] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0034] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0035] Reference Figures 1 to 6 As shown, this utility model provides a drilling device for a bridge crash barrier, including: a support beam 1, a limiting rod 2, a moving beam 3, and a drilling machine 4.

[0036] In this embodiment, there are two support beams. The support beams are used to rest on the crash barrier 5. The two support beams 1 are arranged opposite to each other. A connecting beam 11 is connected between the ends of the two support beams 1. Inner grooves a are formed on the opposite sides of the two support beams 1.

[0037] Two limiting rods 2 are adjustablely installed on the support beam 1. The limiting rods 2 are used to press against the side of the crash barrier 5.

[0038] When using, combine Figure 6As shown, one end of the two supporting beams 1 rests on the crash barrier. Figure 6 The diagram illustrates the use of openings in the guardrails on opposite sides of two bridges, specifically the installation of anti-glare panels on the outer side of the guardrails in the median strip of the bridge. The two ends of the support beam rest on the two guardrails respectively. The positions of the two limiting rods are moved so that the two limiting rods on each support beam are positioned between the two guardrails, and that the two limiting rods abut against the opposite sides of the two guardrails, thereby preventing the support beams from moving.

[0039] In some embodiments, when holes are drilled in the guardrails on opposite sides of the bridge, i.e. Figure 6 When there is only one crash barrier, the two limiting rods on each support beam are moved so that the two limiting rods are respectively positioned on opposite sides of the crash barrier, and the two limiting rods are clamped to the crash barrier, thereby making the support beam stably set on the crash barrier. Preferably, a counterweight is installed on one end of the support beam located on the inner side of the crash barrier, so that the other end of the support beam is cantilevered on the outer side of the crash barrier.

[0040] The movable beam 3 is arranged along the width direction of the supporting beam. Both ends of the movable beam 3 are slidably positioned within the inner sliding grooves a of the two supporting beams 1. The inner sliding grooves are arranged along the length direction of the supporting beams, allowing the movable beam to be positioned along the length direction of the supporting beams. A height-adjustable hanging column assembly 6 is installed on the movable beam 3.

[0041] The drilling machine 4 is installed at the lower end of the column assembly 6.

[0042] After installing the support beam onto the crash barrier, adjust the height of the hanging column assembly so that the drill rod of the drilling machine is aligned with the opening in the crash barrier. Then, adjust the position of the drilling machine along the length of the support beam so that the drill bit is against the opening. After starting the drilling machine, use the drill bit to drill a hole at the opening to install the anti-glare panel.

[0043] See Figure 4 As shown, flange plates 12 are formed on the opposite sides of the two supporting beams 1, and outer grooves b are formed on the opposite sides of the two supporting beams 1. In this embodiment, see reference... Figure 3 As shown, the outer and inner sliding grooves are respectively provided on the inner and outer sides of the support beam. The limiting rod 2 has a side slider. The side slider slides in the outer sliding groove b. A locking element 21 is installed on the limiting rod 2. The locking element 21 is used to lock the flange plate 12.

[0044] Combination Figure 3 and Figure 4 As shown, the flange plate 12 has multiple locking holes. The multiple locking holes are spaced apart along the length direction of the flange plate 12. The locking member 21 is detachably installed on the limiting rod 2 and is detachably inserted into a locking hole.

[0045] In a preferred embodiment, the upper end of the limiting rod 2 has a threaded hole. The locking member 21 has an external thread. The locking member 21 is screwed into the threaded hole of the limiting rod 2.

[0046] See Figure 4 and Figure 5 As shown, in this embodiment, the hanging column assembly 6 includes: a plug rod 61, a socket sleeve 62, and a retaining member.

[0047] The insertion rod 61 is vertically positioned. The upper end of the insertion rod 61 is mounted on the moving beam 3. The socket sleeve 62 is coaxially positioned with the insertion rod. The socket sleeve 62 is vertically mounted on the drilling machine 4. The lower end of the insertion rod 61 is movably inserted into the socket sleeve 62. A retaining element is installed on the insertion rod 61.

[0048] The locking element is used to secure the socket sleeve 62. For details, please refer to [link / reference needed]. Figure 5 As shown, the socket sleeve 62 has a guide hole. The guide hole is arranged along the axial direction of the socket sleeve 62. The retaining member has external threads. The insert rod 61 has a threaded hole. The retaining member is screwed into the threaded hole. The middle part of the retaining member slides in the guide hole. A pressure plate 631 is formed at the end of the retaining member away from the insert rod 61. The pressure plate 631 presses against the outside of the socket sleeve 62.

[0049] Continue reading Figure 5 As shown, the movable beam 3 has an upper sliding groove c. The upper sliding groove c is arranged along the length direction of the movable beam 3. An upper slider 611 is formed at the upper end of the insertion rod 61. The upper slider 611 slides in the upper sliding groove c.

[0050] In this embodiment, the inner and outer slideways are dovetail grooves. The upper slideway has a T-shaped cross-section. Correspondingly, the cross-sections of the two ends of the moving beam, the side sliders, and the upper slider are adapted to the inner, outer, and upper slideways.

[0051] This invention relates to a drilling device for bridge crash barriers. A steel beam frame, consisting of a support beam and a connecting beam, is then installed on the crash barrier via a limiting rod. Adjusting the position of the limiting rod allows the steel beam frame to move along the length of the crash barrier, thus adjusting the position of the drilling machine along that length. A suspension rod assembly adjusts the position of the drilling machine along the height of the crash barrier, and adjusting the position of the moving beam along the length of the support beam adjusts the position of the drilling machine along the thickness of the crash barrier. This allows the drilling machine to be flexibly positioned to align with the openings on the crash barrier. This drilling device for bridge crash barriers is easy and quick to install, requires no large machinery, shortens construction time, improves construction efficiency, and saves construction costs.

[0052] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
