Description

Technical Field

[0001] This utility model belongs to the technical field of drilling equipment and relates to a bridge deck drilling device. Background Technology

[0002] Currently, many bridges, roads, or areas use simple steel structure guardrails. During installation, holes are usually drilled in the ground, and then the bottom rods of the steel structure guardrail are inserted into the holes for installation and fixation. The common drilling method is for the operator to hold an electric drill in the ground. When drilling, the operator needs to keep the drill bit upright to prevent drilling the hole crookedly, so as to facilitate the subsequent installation of the guardrail, ensure the drilling quality, and prevent the drill bit from breaking in the hole. The operator consumes a lot of physical strength during the operation. Utility Model Content

Detailed Implementation

[0015] The present invention will now be described in detail with reference to the accompanying drawings: As shown in Figures 1-3, a bridge deck drilling device includes a support 1, which is made of stainless steel. A horizontally positioned base plate 2 is provided at the bottom of the support 1. A vertically positioned guide rod 3 is fixed on the base plate 2. The guide rod 3 has a rectangular cross-section. An electric drill 4 is mounted on the guide rod 3. The electric drill 4 is a conventional electric drill, currently mostly used by operators to drill holes on the ground by hand. The electric drill 4 can move back and forth along the length of the guide rod 3. Specifically, a sleeve 5 adapted to the guide rod 3 is fitted onto the guide rod 3. The sleeve 5 can move back and forth along the length of the guide rod 3. A mounting bracket 6 is fixed to one side of the sleeve 5, and the electric drill 4 is fixed to the mounting bracket 6. That is, the electric drill 4 is connected to the sleeve 5 through the mounting bracket 6, and the sleeve 5 can drive the electric drill 4 to move back and forth along the length of the guide rod 3. A rack 7 is provided on the side of the guide rod 3 near the electric drill 4 along the length of the guide rod 3. A through hole 8 is provided on the side wall of the sleeve 5, located near the rack 7. The guide rod 3 is positioned at the through hole 8. 3. A rotating shaft 9 is arranged perpendicularly to each other and is mounted on a mounting bracket 6. A gear 10 that meshes with a rack 7 is sleeved on the rotating shaft 9. The gear 10 can rotate with the rotating shaft 9, that is, the rotating shaft 9 drives the gear 10 to rotate. One end of the rotating shaft 9 is provided with a rocker arm 11 for rotating the rotating shaft 9. In use, the sleeve 5 can be moved back and forth (i.e., up and down) in the length direction of the guide rod 3 by rotating the gear 10, thereby causing the electric drill 4 to move up and down to perform drilling operations. The operation mode of this device is similar to that of existing drilling machines, making it more convenient for operators to operate and improving the drilling effect. The electric drill 4 is equipped with a drill bit 12, and the drill bit 12 is arranged parallel to each other with the guide rod 3 (i.e., vertically). Since the drill bit 12 is located above the base plate 2, the base plate 2 is provided with a through hole 13 corresponding to the drill bit 12. When the drill bit 12 moves downward, it can pass through the through hole 13 to drill a hole in the ground. In order to facilitate the quick movement of the sleeve 5, a gripper 14 is provided on the sleeve 5.

[0016] Because this device is relatively heavy, in order to facilitate its movement, the support 1 has two wheels 15 on one side of the bottom and two support rods 16 on the other side of the bottom. The support 1 has a handle 17 on the side near the support rods 16 for pushing the support 1. When it is necessary to move the device, simply lift one side of the support rod 16 with the handle to push the device to move. During use, the support rods 16 have a large friction with the ground, which can prevent the support 1 from moving during the drilling process and affecting the drilling.

[0017] The method of using this utility model is as follows: When drilling holes in the bridge deck, first move the bracket 1 to the appropriate position, then install the drill bit 12 on the electric drill 4, aligning the drill bit 12 with the appropriate position. Then start the electric drill 4, which will drive the drill bit 12 to rotate. At this time, the operator can turn the rocker arm 11, which will drive the rotating shaft 9 and gear 10 to rotate. The gear 10 and rack 7 will drive the sleeve 5 and the electric drill 4 to descend, allowing the drill bit 12 to pass through the through hole 13 and drill a hole in the ground. When the drill bit 12 reaches the appropriate depth, turn the rocker arm 11 in the opposite direction to raise the sleeve 5 and the electric drill 4, completing the drilling operation. When it is necessary to move this device, the drill bit 12 can be removed from the electric drill 4 to prevent it from affecting normal movement.
