Technical Field
[0001] The utility model relates to the technical field of drilling, in particular to a pedal-type drilling tool. Background Art
[0002] Currently, manual percussion punching is commonly used for piercing buried gas pipelines in sandy or complex surface environments like the Gobi Desert. This method typically requires three people: one person is responsible for holding the punching rod, which weighs approximately 15 kilograms, to perform the percussion drilling (the required hole depth is usually 12-20 cm); one person is responsible for holding the testing instrument to connect the punching rod for testing; and another person is responsible for recording the data.
[0003] In the existing technology, due to the heavy weight of the punch rod itself, workers have to consume a lot of physical energy when carrying and repeatedly lifting and hammering, and are easily fatigued. In addition, the equipment is bulky and the bottom support design is unreasonable, making it very inconvenient to move and position on soft sand. At the same time, it relies on pure manual impact, and the drilling speed is slow. Especially when multiple inspection holes need to be drilled, the overall operation efficiency is low. If hard interlayers or gravel common in the Gobi Desert are encountered, penetration is difficult, and it may even cause damage to the drill bit or operation failure.
[0004] Therefore, it is necessary to provide a new pedal-type drill to solve the problems of the technologies described above. Utility Model Content

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0025] The specific implementation of the present invention is described in detail below with reference to specific embodiments.
[0026] See also Figures 1 to 5 An embodiment of the present invention provides a pedal-operated drill, which includes a U-shaped frame 1, a mounting frame 2, a drill rod 3 and a driving component 5.
[0027] In the embodiments of the present invention, please refer to Figures 1 to 5 A slidingly connected mounting frame 2 is set up in the U-shaped frame 1. Specifically, side cavities 1a are opened on both side walls of the U-shaped frame 1, and a guide rod 11 is fixedly installed on each side cavity 1a. Guide blocks 22 are fixedly installed on the outer walls of both sides of the mounting frame 2, and the two guide blocks 22 are respectively sleeved on the two guide rods 11 and slidably connected to the guide rods 11. A support spring 12 is sleeved on each guide rod 11, and one end of the support spring 12 is fixedly connected to the bottom of the side cavity 1a, and the other end of the support spring 12 is fixedly connected to the lower surface of the guide block 22, and a push rod 21 is fixedly installed on the top of the mounting frame 2, and the push rod 21 passes through the through hole opened at the top of the U-shaped frame 1 and is fixedly installed with a handle 23;
[0028] A rotatably connected drill rod 3 is mounted at the bottom of the mounting frame 2 , a drill bit 4 is mounted at the bottom of the drill rod 3 , and a rotation driving component 5 for driving the drill rod 3 to rotate is mounted inside the mounting frame 2 .
[0029] It should be noted that when drilling a hole in the Gobi Desert, the U-shaped frame 1 is aligned with the desired drilling position, and the worker pushes the push handle 23 to drive the mounting frame 2 to slide down along the guide rod 11 along with the guide block 22 until the drill bit 4 contacts the Gobi Desert. Then, the drill rod 3 is rotated by stepping on the curved pedal 55 on the driving component 5. Therefore, the rotating drill rod 3 cooperates with the downward thrust of the push rod 21 to quickly drill a hole in the Gobi Desert.
[0030] It is worth noting that the drill bit 4 can be fixedly installed at the bottom of the drill rod 3 by means of a threaded fixed connection or a screw fixed connection, which facilitates the replacement of the damaged drill bit 4, and a spiral blade 31 is fixedly installed on the drill rod 3, so as to facilitate the discharge of sand and soil when the drill bit 4 drills a hole.
[0031] Among them, a horizontally arranged curved portion 13 is provided on the plate heads on both sides of the U-shaped frame 1. The curved portion 13 arranged at the bottom of the U-shaped frame 1 can increase the contact area between the U-shaped frame 1 and the Gobi desert and reduce the depth of the bottom of the U-shaped frame 1 inserted into the Gobi desert. A rubber sleeve can be provided on the curved portion 13 to effectively protect the curved portion 13.
[0032] In the embodiments of the present invention, please refer to Figures 1 to 5 The driving component 5 includes a worm gear 51 and a worm 52. The worm gear 51 is fixedly mounted on the top of the drill rod 3. Both ends of the worm 52 are fixedly mounted with rotating shafts 53, and the two rotating shafts 53 are fixedly mounted in the mounting frame 2 through brackets 54. The worm 52 is meshed with the worm gear 51, and an arc-shaped pedal 55 is fixedly mounted on the rotating shafts 53 on both sides of the worm 52. An arc-shaped guide rod 56 is fixedly mounted on the bottom of the arc-shaped pedal 55, and the arc-shaped guide rod 56 is inserted into the arc-shaped through hole 2a opened at the bottom of the mounting frame 2 and is slidably connected to the arc-shaped through hole 2a. An arc spring 57 is sleeved on the arc guide rod 56, one end of the arc spring 57 is fixedly connected to the lower plate surface of the arc pedal 55, and the other end of the arc spring 57 is fixedly connected to the inner bottom wall of the mounting frame 2.
[0033] It should be noted that: the staff steps on the arc pedal 55, so that the arc pedal 55 drives the rotating shaft 53 to deflect on the bracket 54. Since the worm 52 is meshed with the worm gear 51, the worm gear 51 drives the drill rod 3 to rotate. When the arc pedal 55 is stepped on once, the arc guide rod 56 slides along the arc through hole 2a and compresses the arc spring 57. Therefore, when the arc pedal 55 is released, the arc pedal 55 is reversed and reset under the action of the arc spring 57. Then, the push rod 21 is pushed down and the arc pedal 55 is stepped on again to make the drill bit 4 drill again until the hole depth reaches the requirement. The purely mechanical structure of this drill does not require power supply and can effectively adapt to the use in the field environment.
[0034] The use of a foot-operated curved pedal 55 converts the pedal force into a powerful rotational torque of the drill rod 3 through the worm 52 and worm gear 51 mechanism, thereby solving the problem of laborious manual impact. Compared with the impact type, the drill bit 4 combined with the spiral blade 31 has a faster drilling speed and stronger penetration ability in sandy and hard formations, thereby effectively improving the working efficiency.
[0035] Furthermore, two symmetrically distributed feet 551 are fixedly installed on the lower surface of the curved pedal 55 away from the rotating shaft 53. The feet 551 are arranged so that when the curved pedal 55 rotates toward the inner bottom wall of the mounting frame 2, the feet 551 can first contact the inner bottom wall of the mounting frame 2, thereby avoiding the hidden danger of the curved pedal 55 being pressed on the worm gear 51.
[0036] In addition, in order to reduce the weight of the device, the U-shaped frame 1 and the installation frame 2 are made of light alloy.
[0037] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
