Description

Technical Field

[0001] The present invention relates to the technical field of exploration drills, and particularly to impact geological exploration drills. Background Art

[0002] An impact geological exploration drill is a drilling device for geological exploration, especially suitable for drilling in relatively hard rock formations or deep underground rock and soil. Its main working principle is to break the rocks in the formation through impact, so as to achieve the cutting and sampling of rock and soil.

[0003] In the prior art, the ropes for towing the impact hammer of the impact geological exploration drill are often ignored during use, and the wear condition of the towing ropes cannot be detected in time, resulting in the sudden breakage of the towing ropes, which poses a great safety hazard. Summary of the Invention

[0004] The purpose of the present invention is to solve the deficiencies in the prior art and propose an impact geological exploration drill.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions:

[0006] An impact geological exploration drill, including a drill body and a towing rope. The drill body is provided with an impact hammer and a winding mechanism for the sinking of the impact sampling pipe. Both ends of the towing rope are respectively connected to the impact hammer and the winding mechanism. The drill body further includes: a wheel seat fixedly installed on the top of the drill body, a guide wheel rotatably installed in the wheel seat, the towing rope bypassing the surface of the guide wheel, a first bracket fixedly installed on the surface of the wheel seat, and an infrared rangefinder fixedly installed on the top of the first bracket; a safety mechanism provided on the surface of the drill body, the towing rope passing through the safety mechanism, and the safety mechanism being used for limiting and cleaning the towing rope.

[0007] As a further solution of the present invention, the safety mechanism includes a second bracket fixedly installed on the surface of the drill body. The interior of the second bracket is of a hollow structure. A first slider and a second slider are symmetrically and slidably installed in the second bracket. A guiding component is fixedly installed between the first slider and the second slider. Two locking blocks are symmetrically and fixedly installed in the second bracket.

[0008] As a further solution of the present invention, the guiding component includes two adapter plates and two smooth wheels. The two smooth wheels are rotatably installed between the two adapter plates. The two adapter plates are respectively fixedly installed on the adjacent sides of the first slider and the second slider. The towing rope passes between the two smooth wheels. Grooves adapted to the towing rope are formed on the adjacent sides of the two locking blocks.

[0009] As a further solution of the present invention, an adjusting screw rod is rotatably installed in the second bracket. One end of the adjusting screw rod passes through the outer surface of the first slider and is threadedly connected thereto. A support shaft is fixedly installed in the second bracket. One end of the support shaft passes through the second slider and is slidably connected thereto. A fine-tuning motor and a microcontroller are fixedly installed on one side of the second bracket away from the drilling rig body.

[0010] As a further solution of the present invention, the output end of the fine-tuning motor is fixedly installed at the rotation center of one end of the adjusting screw rod. The microcontroller is used to receive the signal sent by the infrared rangefinder after detecting the traction rope and automatically control the fine-tuning motor to start until the traction rope is locked when the traction rope is severely worn.

[0011] As a further solution of the present invention, transfer blocks are fixedly installed at the bottoms of the first slider and the second slider. Each transfer block has an L-shaped structure. A limiting convex block in an arc-shaped structure is provided on the surface of each transfer block. A cleaning brush and a baffle are provided between the two transfer blocks.

[0012] As a further solution of the present invention, the cleaning brush has a circular ring structure. Brush hairs are evenly distributed on the inner arc surface of the cleaning brush. A chute adapted to the limiting convex block is opened at the bottom of the cleaning brush. The cleaning brush is slidably installed between the two transfer blocks through the chute. The baffle has a circular structure. A round hole adapted to the traction rope is opened on the surface of the baffle. The baffle is placed on the top of the cleaning brush and is fixedly installed with the two transfer blocks through bolts.

[0013] As a further solution of the present invention, a cover plate is fixedly installed on the top of the second bracket. A protective cover for protecting the fine-tuning motor is fixedly installed on one side of the second bracket. A waist-shaped slot hole penetrating its outer surface is opened on the top of the cover plate. The waist-shaped slot hole is used for the traction rope to pass through.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. By setting up a safety mechanism and using an infrared rangefinder to detect the state of the traction rope when it passes through the guide wheel, it can be obtained whether the wear amount of the traction rope exceeds the safety value by comparing the front and back data. When the traction rope is severely worn, the fine-tuning motor in the safety mechanism starts to drive the adjusting screw rod to rotate, and then drives the guiding assembly to approach the adjacent locking block in the second bracket until the traction rope is clamped and limited, effectively avoiding the sudden breakage of the traction rope due to untimely inspection and improving the safety of the equipment during use;

[0016] 2. By setting up a cleaning brush, the surface of part of the traction rope entering the foundation can be cleaned, preventing the traction rope from carrying sediment and then rubbing against the guide wheel, avoiding increased wear and tear due to sediment on both of them, and further preventing the short service life of the traction rope, thereby further improving the safety of the equipment during use.

[0029] Refer to Figures 1-8 , an impact type geological exploration drill, comprising a drill body 1 and a towing rope 2. The drill body 1 is provided with a hammer for impacting the sampling pipe to sink and a winding mechanism. The two ends of the towing rope 2 are respectively connected to the hammer and the winding mechanism. The drill body 1 further comprises: a wheel seat 3, the wheel seat 3 is fixedly installed on the top of the drill body 1, a guide wheel 4 is rotatably installed in the wheel seat 3, the towing rope 2 bypasses the surface of the guide wheel 4, a first bracket 5 is fixedly installed on the surface of the wheel seat 3, and an infrared rangefinder 6 is fixedly installed on the top of the first bracket 5; a safety mechanism 7, the safety mechanism 7 is arranged on the surface of the drill body 1, the towing rope 2 passes through the safety mechanism 7, and the safety mechanism 7 is used for limiting and cleaning the towing rope 2.

[0030] During use, by setting the safety mechanism 7 and using the infrared rangefinder 6 to detect the state of the towing rope 2 when passing through the guide wheel 4, it can be obtained whether the wear amount of the towing rope 2 exceeds the safety value according to the comparison of the front and rear data. When the towing rope 2 is severely worn, the fine-tuning motor 702 in the safety mechanism 7 starts to drive the adjusting screw rod 703 to rotate, and then drives the guiding assembly 705 to approach the adjacent locking block 706 in the second bracket 701 until the towing rope 2 is clamped and limited, and then the towing rope 2 is replaced in time, effectively avoiding the sudden breakage of the towing rope 2 due to untimely inspection and improving the safety of the equipment during use.

[0031] In this embodiment, the safety mechanism 7 includes a second support 701 which is fixedly installed on the surface of the drilling rig body 1.
