Description

Technical Field

[0001] The utility model relates to the field of highway survey, in particular to a highway drilling device. Background Art

[0002] With the rapid development of society, the construction of highway bridges is also increasing day by day. In the process of highway bridge construction, hole survey is a very important link, among which highway hole survey equipment plays a vital role.

[0003] In the process of drilling holes in existing drilling equipment, the coolant will mix with the sand to form mud. When the drill bit is running at high speed, the mud will splash everywhere. The existing solution is usually for the operator to find an idle baffle to support and fix it between the feet and the bracket to play a shielding role, which is very cumbersome and not conducive to construction.

[0004] After drilling is completed, coring is usually done manually by using metal tools to knock on the outside of the drill bit to remove the core sample. This process will cause dents on the side of the drill bit, causing the drill bit to be damaged and unusable, thereby increasing the company's economic expenditure. A damaged drill bit will delay the construction progress. Utility Model Content

[0008] Further optionally, the drill bit is rotationally connected to the lifting platform via a rotating sleeve and is synchronously driven with the driving motor via a synchronous belt.

[0009] Further optionally, a through hole is formed in the rotating sleeve concentrically with the lifting platform and the drill bit.

[0010] Further optionally, the extrusion assembly includes a pressing plate arranged inside the drill bit, and a push rod penetrating the through hole is arranged on the upper part of the pressing plate, and the push rod extends to the gantry and is connected and fixed thereto.

[0020] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods:

[0021] like Figure 1 As shown, a highway drilling device includes a mobile trolley 1, a gantry 2 is provided on the mobile trolley 1, a lifting platform 3 which can be adjusted up and down by rotating a lead screw 5 is provided on the gantry 2, a driving motor 11 is provided on the upper part of one side of the lifting platform 3 and a drill bit 10 is connected to the lower part of the other side, an extrusion component which can quickly core out is provided inside the drill bit 10, and protective components are provided on both sides of the mobile trolley 1 to prevent mud from splashing during drilling operation.

[0022] like Figure 1 As shown, the drill bit 10 is rotationally connected to the lifting platform 3 via a rotating sleeve 6 and is synchronously driven by a driving motor 11 via a synchronous belt.

[0023] like Figure 1 As shown, the rotating sleeve 6 is provided with a through hole coaxially with the lifting platform 3 and the drill bit 10 .

[0024] like Figure 1 , 4 As shown, the extrusion assembly includes a pressing plate 9 arranged inside the drill bit 10, and a push rod 8 penetrating through a through hole is arranged on the upper part of the pressing plate 9. The push rod 8 extends to the gantry 2 and is connected and fixed thereto.

[0025] like Figure 1 , 3 As shown in , 4, the protection component includes a storage box 12 fixed on the left and right sides of the mobile trolley 1, a rewinding component is arranged inside the storage box 12, a protection cloth 15 is wrapped around the rewinding component, the protection cloth 15 extends to the outside of the storage box 12 and is connected to a connecting piece 13, and a hook 14 is arranged on the upper part.

[0026] like Figure 3 As shown, the rewinding assembly includes a central shaft 18 supported inside the storage box 12 , the central shaft 18 is connected and fixed to the rotating shaft 16 via a coil spring 17 , and the rotating shaft 16 is connected and fixed to the end of the protective cloth 15 .

[0027] like Figure 1 , 4 As shown, a hanging rod 7 is arranged just above the hook 14 , and the hanging rod 7 is connected and fixed to the moving vehicle 1 .

[0028] The implementation principle of a road drilling device in the embodiment of the present application is:

[0029] Before drilling, first pass the push rod 8 on the pressing sheet 9 through the drill bit 10 and the through hole on the rotating sleeve 6 and the lifting platform 3, and connect and fix it with the support frame 8 to prevent it from rotating with the drill bit;

[0030] After being fixed, the driving motor 11 is started to rotate the drill bit 10, and the rotating drill bit 10 is brought into contact with the ground by shaking the hand wheel 4, and the hooks 14 on both sides are pulled at the same time. When the hooks 14 are pulled, the protective cloth 15 is pulled out from the storage box 12, and then the hooks 14 are hung on the hanging rod 7, and a shielding plate is formed at the same time to prevent the coolant and soil from mixing into mud and splashing around and on the workers during the drilling operation, and prepare for the drilling and coring operation;

[0031] When drilling, turning the hand wheel 4 drives the lead screw 5 to rotate clockwise at the same time. When the lead screw 5 rotates, the drill bit 10 on the lifting platform 3 will gradually descend and gradually reach the drilling depth. When the drill bit 10 descends, the pressing plate 9 will reversely move in the drill bit 10 and gradually rise. When the drilling depth is reached, the driving motor 11 is stopped, and the hand wheel 4 is turned in the opposite direction to make the drill bit 10 rise. When the drill bit 10 rises, the pressing plate 9 will gradually descend. When it descends, the core sample in the drill bit 10 will be pushed out of the outside of the drill bit 10, thereby completing the core removal work, better ensuring the integrity of the drill bit, avoiding the formation of pits, which makes the drill bit 10 unable to continue to be used, thereby increasing the service life of the drill bit 10.
