Bridge pile foundations are usually composed of piles and pile caps. During the installation of piles and pile caps, and pile caps and bridge components, bolts, nuts or anchor rods are used for reinforcement, and small drilling equipment is used for further processing.

[0003] Basic small drilling equipment is generally processed using a handheld electric drill. This method requires manual pressure to make the drill bit drill continuously, which is labor-intensive. In addition, the electric drill needs to be manually kept vertical. As the drilling operation proceeds, it not only affects the quality of the hole, but also the drill rod is easily damaged, which has certain limitations. Utility Model Content

[0004] The purpose of this utility model is to provide a drilling device for bridge pile foundation construction, which has the advantage of stable operation. It solves the problems of small drilling devices for foundations requiring manual pressure to make the drill bit drill in continuously, resulting in high labor intensity. In addition, manual maintenance of the verticality of the electric drill is required, which not only affects the quality of the hole opening, but also makes the electric drill rod easy to be damaged as the drilling operation progresses.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drilling device for bridge pile foundation construction, comprising:

[0006] Mounting bracket, with jog switches fixedly connected to the left and right sides of the top of the mounting bracket, and a controller bolted to the inside of the mounting bracket;

[0007] A lifting mechanism is installed on the side of the mounting frame. The lifting mechanism includes a storage sleeve. A lifting rod is slidably installed on the top of the inner cavity of the storage sleeve. A bidirectional air pump is fixedly installed on the side of the storage sleeve away from the mounting frame.

[0008] A safety limiting mechanism is installed on a storage sleeve. The safety limiting mechanism includes a screw sleeve, the inner ring of which is threadedly connected to a screw rod. A limiting block is fixedly connected to the top of the screw rod, and a pressure sensor is fixedly embedded in the top of the limiting block.

[0009] A drilling mechanism is mounted through a mounting frame. The drilling mechanism includes an auxiliary frame, and a motor is bolted to the center of the top of the auxiliary frame. A drill rod is fixedly mounted to the output end of the motor.

[0010] As a preferred embodiment of the drilling equipment for bridge pile foundation construction according to this utility model, an elastic rubber block is fixedly connected to the top of the mounting frame and located at the top of the jog switch, and the outer ring of the lifting rod slides in contact with the inner wall of the storage sleeve and is sealed.

[0011] As a preferred embodiment of the drilling equipment for bridge pile foundation construction according to this utility model, the surface of the storage sleeve is fixedly connected to the connection of the mounting frame, and one end of the bidirectional air pump is in communication with the storage sleeve.

[0012] In a preferred embodiment of the drilling equipment for bridge pile foundation construction according to this utility model, the top of the lifting rod is fixedly connected to the connection point of the auxiliary frame, and the auxiliary frame passes through the mounting frame and slides in contact with the mounting frame.

[0013] As a preferred embodiment of the drilling equipment for bridge pile foundation construction according to this utility model, a guide rod is fixedly connected to the bottom of the auxiliary frame, and the guide rod passes through the mounting frame and slides in contact with the mounting frame.

[0014] In a preferred embodiment of the drilling equipment for bridge pile foundation construction according to this utility model, the top of the limiting block contacts the bottom of the auxiliary frame, an auxiliary sleeve is fixedly connected to one side of the receiving sleeve, and the surface of the auxiliary sleeve is movably connected to the threaded sleeve through a damping bearing.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model, by setting a safety limit mechanism, can drive the screw sleeve to rotate. Under the threaded transmission, the screw can be flexibly displaced to change the initial height of the limit block. Then, when the auxiliary frame moves down and contacts the pressure sensor, the pressure sensor detects the presence of pressure and transmits the signal to the controller. The controller automatically controls the bidirectional air pump to stop working, thus achieving the function of limit protection and ensuring the drilling depth.

[0018] 2. By setting up a lifting mechanism, this utility model can naturally move the lifting rod upward when the bidirectional air pump is working to inflate the storage sleeve, and naturally move the lifting rod downward when the bidirectional air pump is working to extract the gas from the storage sleeve, thereby flexibly adjusting the height of the auxiliary frame.

[0019] 3. By setting up a drilling mechanism, this utility model can drive the drill rod to rotate while the motor is working, so that the drill rod can continuously penetrate downwards when the auxiliary frame moves down stably, thereby achieving the purpose of stable drilling.

[0026] Please see Figures 1-5 A drilling device for bridge pile foundation construction includes a mounting frame 1. A jog switch 7 is fixedly connected and installed on both the left and right sides of the top of the mounting frame 1. A controller 6 is bolted on the inner side of the mounting frame 1.

[0027] Furthermore, an elastic rubber block 2 is fixedly connected to the top of the mounting bracket 1 and to the top of the jog switch 7.

[0028] Furthermore, it also includes a lifting mechanism 4, which is installed on the side of the mounting frame 1. The lifting mechanism 4 includes a storage sleeve 402, a lifting rod 401 is slidably installed on the top of the inner cavity of the storage sleeve 402, and a bidirectional air pump 403 is fixedly installed on the side of the storage sleeve 402 away from the mounting frame 1.

[0029] Furthermore, the outer ring of the lifting rod 401 slides into contact with the inner wall of the storage sleeve 402 and is sealed.

[0030] Furthermore, the surface of the storage sleeve 402 is fixedly connected to the mounting bracket 1, and one end of the bidirectional air pump 403 is in communication with the storage sleeve 402. When the auxiliary frame 502 is raised or lowered, the controller 6 controls the bidirectional air pump 403 to inflate or deflate, causing a change in the amount of gas inside the storage sleeve 402. This causes the lifting rod 401 to move up and down. When the bidirectional air pump 403 is inflating, the lifting rod 401 gradually moves upward; when the bidirectional air pump 403 is deflateing, the lifting rod 401 gradually moves downward, thus allowing for flexible adjustment of the height of the auxiliary frame 502.

[0031] Furthermore, it also includes a safety limit mechanism 3, which is installed on the storage sleeve 402. The safety limit mechanism 3 includes a screw sleeve 303, the inner ring of which is threadedly connected to a screw rod 306, the top of which is fixedly connected to a limit block 301, and the top of the limit block 301 is fixedly embedded with a pressure sensor 302.

[0032] Furthermore, an auxiliary sleeve 305 is fixedly connected to one side of the storage sleeve 402, and the surface of the auxiliary sleeve 305 is movably connected to the threaded sleeve 303 through a damping bearing.

[0033] Furthermore, the inner diameter of the auxiliary sleeve 305 is larger than the outer diameter of the screw 306. A protrusion 307 is fixedly connected to the side of the screw 306 near the receiving sleeve 402. A groove 304 that mates with the protrusion 307 is vertically opened on the surface of the receiving sleeve 402. When there is a need for fixed-distance drilling, before the auxiliary frame 502 is raised or lowered, the screw sleeve 303 is pre-driven to rotate. Under the guidance of the threaded transmission and the protrusion 307 and the groove 304, the screw 306 will gradually move upward to adjust the initial height of the limit block 301. When the auxiliary frame 502 gradually moves downward and contacts the limit block 301, the screw sleeve 303 detects the presence of pressure and sends a signal to the controller 6. The controller 6 automatically controls the bidirectional air pump 403 to stop working. At this time, the lifting rod 401 and the auxiliary frame 502 cannot move downward again, ensuring the drilling depth of the drill rod 504.

[0034] Furthermore, it also includes a drilling mechanism 5, which is installed through the mounting frame 1. The drilling mechanism 5 includes an auxiliary frame 502, and a motor 503 is bolted to the center of the top of the auxiliary frame 502. A drill rod 504 is fixedly installed at the output end of the motor 503.

[0035] Furthermore, the top of the lifting rod 401 is fixedly connected to the auxiliary frame 502, and the auxiliary frame 502 passes through the mounting frame 1 and slides in contact with the mounting frame 1.

[0036] Furthermore, a guide rod 501 is fixedly connected to the bottom of the auxiliary frame 502, and the guide rod 501 passes through the mounting frame 1 and slides in contact with the mounting frame 1.

[0037] Furthermore, the top of the limiting block 301 contacts the bottom of the auxiliary frame 502. When drilling is required, the position of the equipment is first adjusted so that the drill rod 504 is aligned with the pre-drilling position. Then, the operator presses down on the elastic rubber block 2 with both feet. The elastic rubber block 2 undergoes elastic deformation, and the jog switch 7 is pressed and turned on. The motor 503 is energized and the drill rod 504 rotates. As the auxiliary frame 502 moves down, the rotating drill rod 504 will drill holes in the bridge piles and pile caps.

[0038] Specifically, anti-slip blocks are fixedly connected to both the left and right sides of the bottom of the mounting bracket 1. The presence of anti-slip blocks increases the contact friction with the placement surface, thereby preventing the mounting bracket 1 from sliding arbitrarily. The top of the mounting bracket 1 has multiple through holes, which are respectively adapted to the guide rod 501, the auxiliary bracket 502 and the motor 503. The outer ring of the screw sleeve 303 is fixedly connected to a torsion block, and the top of the surface of the storage sleeve 402 has an arc groove that cooperates with the torsion block. The external power supply, the controller 6, the jog switch 7 and the motor 503 are connected in series. When the external power supply is turned on and the jog switch 7 is in the on state, the motor 503 will be automatically powered.

[0039] By setting the elastic rubber block 2, it has the advantage of elastic deformation, which can increase the contact friction when in contact with the operator's feet to achieve the purpose of anti-slip protection. It can also prevent the jog switch 7 from being automatically activated when small objects fall on the mounting frame 1, thus improving overall safety. By setting the screw sleeve 303 and the screw 306, it can play the role of threaded transmission. When the screw sleeve 303 is driven to rotate, the screw 306 will move up or down according to the rotation direction of the screw sleeve 303. By setting the protrusion 307 and the groove 304, it can play the role of positioning and guiding, which can prevent the screw 306 from rotating on its own. By setting the guide rod 501, it can pass through the mounting frame 1 to play the role of guiding, which can effectively improve the stability of the vertical displacement of the auxiliary frame 502.

[0040] In practical applications, to prevent gas from leaking out of the storage sleeve 402 at will, a solenoid valve can be installed at the connection between the bidirectional air pump 403 and the storage sleeve 402. The solenoid valve opens when the bidirectional air pump 403 is working and closes when the bidirectional air pump 403 stops working.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
