A grouting composite asphalt pavement construction drilling device

Abstract

This utility model provides a drilling device for grouting composite asphalt pavement construction, relating to the field of asphalt pavement construction. It includes a limiting block inserted into the interior of a mounting base. The drilling assembly can drill holes in the asphalt layer for grouting binder materials, facilitating construction. The limiting assembly also restricts the maximum downward movement of the lifting seat, thereby limiting the drilling depth and ensuring uniform hole depths. This guarantees the uniformity and accuracy of subsequent grouting material injection, resulting in high construction quality. Furthermore, the limiting assembly allows for free adjustment of the maximum limiting position of the lifting seat, adapting to different construction needs. This solves the problem that existing drilling devices lack a drilling depth limiting structure, relying entirely on worker experience to determine drilling depth, leading to inconsistent hole depths and affecting the uniformity and accuracy of subsequent grouting binder material injection.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Please refer to Figures 1 to 6 Example 1:

[0027] This utility model discloses a drilling device for grouting composite asphalt pavement construction, comprising: a drilling assembly 1 and a limiting assembly 2; the drilling assembly 1 includes a mounting base 101, a lifting base 102, a drill chuck 103, and a drive motor 104. The lifting base 102 is inserted into the side of the mounting base 101, and the drill chuck 103 is rotatably connected to the bottom of the lifting base 102. The drive motor 104 is fixedly installed on the top of the lifting base 102, and the shaft of the drive motor 104 is drively connected to the drill chuck 103; the limiting assembly 2 includes a limiting screw 201 and a limiting block 202. The limiting screw 201 is rotatably connected inside the mounting base 101, and the limiting screw 201 is threaded into the limiting block 202. The limiting block 202 is inserted into the mounting base 101. The limiting assembly 2 can limit the lifting base 102 by restricting the lifting base 102. The maximum downward movement distance of the lifting seat 102 limits the drilling depth. When the lifting seat 102 moves down to the set maximum downward movement distance, the seat body of the lifting seat 102 is blocked by the limiting block 202, preventing the lifting seat 102 from moving further down. This limits the maximum downward movement distance of the lifting seat 102, i.e., the maximum drilling depth. The position of the limiting block 202 can be adjusted by the limiting screw 201. When the limiting screw 201 rotates, it can drive the limiting block 202 up and down to change its position through the thread of the rod body. The change in the position of the limiting block 202 changes the maximum downward movement distance of the lifting seat 102 when the seat body of the lifting seat 102 is blocked by the limiting block 202, i.e., the maximum drilling depth. It can be adjusted according to actual construction needs and can be used in different construction conditions, with extremely high flexibility and adaptability.

[0028] The drilling assembly 1 includes a lifting screw 105, which is rotatably connected to the inside of the mounting base 101 and screwed into the inside of the lifting seat 102 via a rod thread. A limiting block 202 is located at the bottom of the lifting seat 102, and a drilling bit is detachably fixed to the bottom of the drill chuck 103. In use, the drilling assembly 1 enables drilling operations in the asphalt layer, facilitating subsequent grouting and bonding material construction. The drive motor 104 can drive the drill chuck 103 and the bottom drilling bit to rotate for drilling operations. The hand crank at the top of the lifting screw 105 can drive the lifting screw 105 to rotate. When the lifting screw 105 rotates, it can drive the lifting seat 102 to move up and down via the rod thread. When the lifting seat 102 moves downward, it can drive the drilling bit to move downward to achieve drilling operations in the asphalt layer. When the lifting seat 102 moves upward, it can drive the drilling bit to move out of the drilled hole. It is convenient and flexible to use.

[0029] The working principle of this embodiment is as follows: Drilling assembly 1 enables drilling into the asphalt layer, facilitating subsequent grouting and bonding material application. Drive motor 104 rotates the drill chuck 103 and the bottom drill bit for drilling. A handwheel at the top of the lifting screw 105 rotates the screw, causing the lifting seat 102 to move up and down via its threaded shaft. When the lifting seat 102 moves downwards, it moves the drill bit downwards to drill into the asphalt layer. When the lifting seat 102 moves upwards, it moves the drill bit out of the drilled hole. Limiting assembly 2 restricts the maximum downward movement of the lifting seat 102, thus limiting the drilling depth. The lifting seat 102 is limited in depth. When the lifting seat 102 moves down to the set maximum downward distance, the seat body of the lifting seat 102 is blocked by the limiting block 202, preventing the lifting seat 102 from moving further down. This limits the maximum downward distance of the lifting seat 102, i.e., the maximum drilling depth. The position of the limiting block 202 can be adjusted by the limiting screw 201. When the limiting screw 201 rotates, it can drive the limiting block 202 to move up and down through the thread of the rod body to change the position. The change in the position of the limiting block 202 changes the maximum downward distance of the lifting seat 102 when the seat body of the lifting seat 102 is blocked by the limiting block 202, i.e., the maximum drilling depth. It can be adjusted according to actual construction needs and can be used in different construction conditions.

[0030] Example 2: Based on Example 1, the limiting component 2 further includes a locking block 203, which is inserted into the interior of the mounting base 101. The bottom of the locking block 203 is provided with a locking top spring 2031, and the two ends of the locking top spring 2031 abut against the bottom of the locking block 203 and the interior of the mounting base 101, respectively.

[0031] The locking block 203 has a splined block 2032 inside, and the top of the limiting screw 201 has a splined groove 2011. The splined block 2032 is inserted into the splined groove 2011. The bottom of the locking block 203 has a locking gear 2033, and the mounting base 101 has a locking tooth groove 1011 inside. When the locking block 203 is not pressed by external force, the locking gear 2033 is inserted into the locking tooth groove 1011 under the action of the locking top spring 2031. In use, considering that vibration will accompany the drilling operation, the locking block 203 can lock the use state of the limiting screw 201, so that when the drilling assembly 1 is working, the limiting screw 201 will not rotate due to vibration or other factors, causing the limiting block 202 to change its use position unexpectedly. Under the action of the locking top spring 2031, when the locking block 203 is not pressed by external force, the locking gear 2033 is inserted into the inside of the locking tooth groove 1011, so the locking block 203 cannot rotate. Under the cooperation of the spline groove 2011 and the spline block 2032, the limit screw 201 is also locked and cannot rotate. When it is necessary to manually adjust the position of the limit block 202, simply press and rotate the locking block 203. When the locking block 203 is pressed, the locking gear 2033 will disengage from the inside of the locking tooth groove 1011, so that the locking block 203 can rotate freely thereafter. When the locking block 203 rotates, the spline block 2032 can drive the limit screw 201 to rotate through the spline groove 2011, thereby realizing the function of adjusting the position of the limit block 202. The adjustment is convenient and quick.

[0032] The working principle of this embodiment is as follows: Under the action of the locking top spring 2031, when the locking block 203 is not pressed by external force, the locking gear 2033 is inserted into the inside of the locking tooth groove 1011, so the locking block 203 cannot rotate. Under the cooperation of the spline groove 2011 and the spline block 2032, the limiting screw 201 is also locked and cannot rotate. When it is necessary to manually adjust the position of the limiting block 202, simply press and rotate the locking block 203. When the locking block 203 is pressed, the locking gear 2033 will disengage from the inside of the locking tooth groove 1011, so that the locking block 203 can rotate freely thereafter. When the locking block 203 rotates, the spline block 2032 can drive the limiting screw 201 to rotate through the spline groove 2011, thereby realizing the function of adjusting the position of the limiting block 202.
