Description

Technical Field

[0001] This utility model relates to the field of tunnel engineering construction, specifically to a drilling device for tunnel engineering construction. Background Technology

[0002] Tunnel construction refers to the creation of underground spaces for purposes such as transportation, water supply, and power transmission through various technical means, including excavation, support, and reinforcement. During tunnel construction, drilling operations are commonly used for installing support anchor structures on the tunnel walls, grouting reinforcement, groundwater control, blasting operations, and installing monitoring instruments. Drilling enhances the stability of the tunnel structure, reduces the risk of water damage, ensures construction safety, and extends the long-term service life of the tunnel.

[0003] Currently, drilling operations often rely on drilling rigs. When drilling into the tunnel walls, due to the considerable height of the holes, support frames are often needed to help operators stand and drill. When drilling another hole, the support frame must be moved before drilling can begin. This frequent movement of the support frame and the constant up-and-down movement of the operators results in very low overall work efficiency. These frequent interruptions disrupt the drilling process and affect the overall progress. Utility Model Content

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] First embodiment:

[0026] See Figures 1-3 As shown, this utility model provides a drilling device for tunnel construction, including a support frame 1, with casters 2 at the bottom of the support frame 1, a travel module 5 for auxiliary movement on the support frame 1, and a support base plate 4 installed on the support frame 1 via an electric support push rod 3, with the support base plate 4 and the travel module 5 being staggered; it also includes a drilling module 6 that slides on the support frame 1, the drilling module 6 including a support box 601 that slides with the support frame 1, and a drilling rig 606 connected inside the support box 601 via an electric telescopic rod 604;

[0027] When drilling into the tunnel wall, the operator is supported by the support frame 1. The travel module 5 drives the support frame 1 to move forward. Multiple casters 2 assist the support frame 1 in moving stably. After moving to the working position, the electric support push rod 3 extends, and the support base plate 4 moves downward. When the support base plate 4 contacts the ground, the support frame 1 is separated from the ground, and the height of the drilling rig 606 can be adjusted. After adjusting to the appropriate height, the electric telescopic rod 604 extends, and the electric telescopic rod 604 pushes the drilling rig 606 toward the tunnel sidewall, enabling drilling into the tunnel wall.

[0028] The second embodiment differs from the first embodiment in that:

[0029] In the structure of the support frame 1, the support frame 1 includes no less than two portal frames 101, the portal frames 101 correspond to each other, and adjacent two portal frames 101 are connected by multiple crossbars 102. The top plate 103 supported by the auxiliary support box 601 is connected to the high end of the adjacent two support frames 1. The multiple crossbars 102 form a staircase structure to help the operator reach the position of the top plate 103. The casters 2 are set at the bottom movable end of the portal frame 101 to help the support frame 1 move. Furthermore, the surface of the crossbars 102 is provided with anti-slip texture to help the operator step on it.

[0030] In a preferred embodiment, a protective net is provided on the upper surface of the support frame 1 to protect the operator.

[0031] The third embodiment differs from the first embodiment in that:

[0032] The top plate 103 has a sliding groove 104 on its surface, and the bottom of the carrying box 601 has a sliding strip 602 that slides with the sliding groove 104. By utilizing the sliding engagement between the sliding groove 104 and the sliding strip 602, the carrying box 601 can be guided and assisted in moving back and forth.

[0033] Furthermore, the output end of the electric telescopic rod 604 is connected to an inner housing 605. The outer wall of the inner housing 605 is provided with a guide bar 607, and the inner wall of the bearing box 601 is provided with a guide groove 603 that slides with the guide bar 607. The working end of the drilling rig 606 extends out of the inner housing 605. By utilizing the sliding engagement between the guide bar 607 on the inner housing 605 and the guide groove 603 on the inner wall of the bearing box 601, the inner housing 605 can be guided, assisting the drilling rig 606 to move left and right. Furthermore, the drilling rig 606 is connected to the inner housing 605 through rubber feet, thereby reducing the vibration of the inner housing 605 during the operation of the drilling rig 606 and protecting the equipment.

[0034] The fourth embodiment differs from the first embodiment in that:

[0035] The traveling module 5 includes a support frame 501 that rotatably engages with the top plate 103. The surface of the portal frame 101 has a circular hole. A rotating sleeve that rotates within the circular hole is located outside the upper sprocket 502. The axis of the rotating sleeve is vertically oriented. The upper sprocket 502 and lower sprocket 503 are rotatably connected to the high and low ends of the support frame 501, respectively. A transmission chain is connected to the outer sides of the upper sprocket 502 and lower sprocket 503. A traveling wheel 504 is mounted on the lower sprocket 503. A rocker arm 505 assists in the rotation of the upper sprocket 502. When the rocker arm 505 is rotated, the travel wheel 504 is driven by the rocker arm. Arm 505 drives the upper sprocket 502 to rotate, and the transmission chain enables the lower sprocket 503 to rotate synchronously, thereby driving the travel wheel 504 to rotate. In conjunction with multiple casters 2, the overall movement of the device is realized. When set up, the bottom of the travel wheel 504 is flush with the bottom of the casters 2. When the travel wheel 504 rolls on the ground, it can drive the overall movement of the device. The travel module 5 uses the rotating sleeve to rotate with the round hole on the top plate 103, which can assist the travel module 5 to continue to rotate, thereby assisting the overall angle adjustment of the support frame 1.

[0036] Furthermore, the support frame 1 is equipped with a battery, and the electric support push rod 3, electric telescopic rod 604, and drilling rig 606 are all electrically connected to the battery. The battery can increase the overall weight of the support frame 1, improve the stability of the device, and provide power to the drilling module 6, electric telescopic rod 604, and drilling rig 606 during use, so that the device can be used without an external power source.

[0037] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
