Description

Technical Field

[0001] This utility model relates to the field of geological exploration technology, specifically to a geological exploration borehole enlargement device for preventing loosening. Background Technology

[0002] In geological exploration, borehole reaming equipment is an important tool for increasing the diameter of boreholes. It is widely used in mineral exploration, geological disaster prevention and other fields. Traditional borehole reaming mostly relies on manual operation, which involves applying pressure to move the drill bit down to enlarge the borehole. However, in actual borehole reaming, external sand or soil can easily collapse into the borehole area, interfering with the exploration work. At the same time, the equipment itself may loosen due to vibration or external forces, further affecting the quality of borehole reaming. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a geological exploration borehole enlargement device for preventing loosening, comprising a carrying plate, guide rods fixedly connected to the four corners of the bottom of the carrying plate, a support plate fixedly connected to the bottom end of the guide rods, an adjustment mechanism installed at the bottom of the carrying plate, and a blocking mechanism installed around the four guide rods. The blocking mechanism includes a support ring, a blocking part, and bolts. The blocking part is integrally formed around the outer periphery of the support ring, and bolts are threadedly connected to both sides of the inner wall of the support ring. Four insert rods are fixedly connected to the bottom of the support ring in a ring shape. A pedal is fixedly connected to both sides of the blocking part.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1 to 4 This utility model provides a geological exploration borehole enlargement device to prevent loosening, including a carrying plate 1. Guide rods 2 are fixedly connected to the four corners of the bottom of the carrying plate 1. A support plate 21 is fixedly connected to the bottom end of the guide rods 2. An adjustment mechanism 3 is installed at the bottom of the carrying plate 1. The adjustment mechanism 3 includes a servo motor 31, a large gear 32, and a first small gear 33. The servo motor 31 is fixedly connected to the top of the carrying plate 1, and the drive end of the servo motor 31 passes through the carrying plate 1 and is fixedly connected to the large gear 32. The two sides of the large gear 32 are respectively meshed with the first small gear 33 and the second small gear 34. A first adjusting rod 331 is fixedly connected through the inside of the first small gear 33, and a second adjusting rod 341 is fixedly connected through the inside of the second small gear 34. A first screw 35 is threaded through the bottom of the first adjusting rod 331, and a second screw 36 is threaded through the bottom of the second adjusting rod 341. A mounting plate 37 is fixedly connected to the bottom ends of the first screw 35 and the second screw 36. Four brackets 38 are fixedly connected to the outer ring, and a guide ring 39 is fixedly connected to one end of each of the four brackets 38. The guide ring 39 is slidably sleeved on the outside of the guide rod 2. The motor 5 is fixedly connected to the bottom center of the mounting plate 37. The first adjusting rod 331 and the second adjusting rod 341 both pass through the carrying plate 1. The first adjusting rod 331 and the carrying plate 1 are rotatably connected by bearings. The second adjusting rod 341 and the carrying plate 1 are rotatably connected by bearings. The first screw 35 and the second screw 36 are of equal length and have the same thread direction. The adjusting mechanism 3 can drive the rotating drill bit 6 to slowly move down to enlarge the hole in the ground. This method can achieve the downward pressing of the drill bit 6 without manual pressing, making the hole enlargement work more time-saving and labor-saving. Moreover, the rotation of the first screw 35 and the second screw 36 can make the drill bit 6 move more smoothly during the downward movement, preventing the deviation of the hole enlargement position caused by uneven force when manually pressing.

[0020] A shielding mechanism 4 is installed around the four guide rods 2. The shielding mechanism 4 includes a support ring 41, a shielding part 42, and bolts 43. The shielding part 42 is integrally formed around the support ring 41, and bolts 43 are threaded to both sides of the inner wall of the support ring 41. Four insert rods 44 are fixedly connected to the bottom of the support ring 41 in a ring. A pedal 45 is fixedly connected to both sides of the shielding part 42. The support ring 41 is slidably sleeved on the outside of the four guide rods 2. One end of the bolt 43 abuts against the guide rod 2. The shielding part 42 is located at the periphery of the four guide rods 2. A motor 5 is installed below the adjusting mechanism 3. A drill bit 6 is fixedly connected to the drive end of the motor 5. The shielding mechanism 4 can prevent externally collapsed sand or soil from entering the borehole expansion area and thus affecting geological exploration. It protects the periphery of the borehole expansion area. Moreover, when the four insert rods 44 move into the soil, it can also increase the stability of the entire device during the borehole expansion process and prevent themselves from loosening and affecting the borehole expansion quality.

[0021] Among them, the servo motor 31 is model ACSM110-G04030LZ, and the motor 5 is model YE2.

[0022] Working principle: Before reaming, adjust the height of the shielding mechanism 4 so that the support ring 41 slides downward along the guide rod 2. Then, step on the foot pedal 45 to insert the insertion rod 44 into the soil, and fix the support ring 41 to the guide rod 2 by tightening the bolts 43 to enhance the overall stability of the device. The shielding part 42 surrounds the reaming area to prevent sand or soil from collapsing into the borehole. The motor 5 drives the drill bit 6 to rotate at high speed. Then, the servo motor 31 is started to drive the large gear 32 to rotate. The large gear 32 drives the first small gear 33 and the second small gear 34 meshing on both sides to rotate synchronously. 3 and the second pinion 34 drive the first screw 35 and the second screw 36 to rotate via the first adjusting rod 331 and the second adjusting rod 341 respectively. Since the first screw 35 is threadedly engaged with the first adjusting rod 331 and the second screw 36 is threadedly engaged with the second adjusting rod 341, the rotational motion can be converted into linear motion, pushing the mounting plate 37 and the drill bit 6 to slowly move down along the guide rod 2, thereby enlarging the hole in the ground. This process does not require manual pressing, and the synchronous drive of the first screw 35 and the second screw 36 ensures that the drill bit 6 moves down smoothly, avoiding hole enlargement deviation caused by uneven force application.
