Description

Technical Field

[0001] This utility model relates to the field of drill barrel technology, specifically to a drill barrel for treating isolated rocks with an added elastic rod mechanism. Background Technology

[0002] In areas with limited clearance and strict vibration restrictions (such as under existing highway bridges), rotary drilling (due to clearance limitations) or impact drilling (due to vibration limitations) cannot be used. Therefore, low-clearance rotary drilling with minimal vibration is generally employed. When encountering isolated boulders during drilling, if the bottom strata are soft or located in a silt layer, the boulders cannot be crushed and extracted by the drill bit and will continue to fall downwards during the drilling process, affecting drilling efficiency. When encountering isolated boulders in soft soil strata using rotary drilling, continuous drilling is generally used to continuously grind and compress the boulders, forcing them into the borehole wall, or drilling with the boulders present. However, this method severely impacts drilling efficiency. Utility Model Content

[0020] 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.

[0021] This utility model provides a boulder treatment drill barrel with an added elastic rod mechanism, including a drill barrel 1 and a drill bit 2. The drill bit 2 is disposed at the lower end of the drill barrel 1. It also includes an elastic rod blocking mechanism, which is disposed near the lower end of the drill barrel 1. The elastic rod blocking mechanism is provided with an inlet 3 for the boulder to pass through.

[0022] Preferably, the elastic rod blocking mechanism includes a connecting plate 4 and multiple elastic rods 5. The connecting plate 4 is located near the lower end of the drill barrel 1. One end of each elastic rod 5 is attached to the connecting plate 4, and the other end is close to the inner wall of the drill barrel 1. The multiple elastic rods 5 are distributed circumferentially along the connecting plate 4, and the gap between two adjacent elastic rods 5 forms the aforementioned inlet 3. It can be understood that when the drill barrel 1 encounters a boulder, it applies pressure to the boulder, causing it to squeeze two adjacent elastic rods 5, thus widening the gap between the two adjacent elastic rods 5 and enlarging the inlet 3. Further, the boulder enters the drill barrel 1 cavity through the inlet 3 of the elastic rod blocking mechanism. Afterward, the elastic rods 5 reset, causing the inlet 3 to also shrink, thus blocking the boulder within the cavity. Therefore, during drilling, the elastic rod blocking mechanism blocks the boulder, preventing it from falling out of the drill barrel 1, and thus pulling the boulder out of the borehole along with the drilled material.

[0023] Preferably, the elastic rod 5 is a steel strand; further, each elastic rod 5 can be a bundle of steel strands consisting of 7 wires with a diameter of 5mm wound together; in addition, steel strands of other sizes and specifications can also be used, and the elastic rod can also be made of other elastic materials.

[0024] Preferably, the lower end of the drill barrel 1 is provided with a mounting block 6. The two ends of the mounting block 6 can be fixed to the inner wall of the drill barrel 1 by welding or other means. The bottom of the connecting plate 4 can be fixed to the mounting block 6 by welding or other means. In addition, the connecting plate 4 can also be provided at the lower end of the drill barrel 1 in other structural forms. No further restrictions are imposed here.

[0025] In addition, preferably, the drill barrel 1 is provided with a stone extraction window 7, which is located near the upper end of the drill barrel 1. The stone extraction window 7 is openable and closable, so that the isolated stone in the cavity of the drill barrel 1 can be removed by opening the stone extraction window 7.

[0026] In addition, a connecting rod 8 is provided at the upper end of the drill barrel 1, and the drill barrel 1 is connected to the drilling machine through the connecting rod 8. Furthermore, the aforementioned drill bit 2 can specifically be a drill tooth keel.

[0027] Compared with the prior art, this utility model provides a drill barrel for handling boulders with an added elastic rod mechanism, which has the following advantages: This utility model adds an elastic rod blocking mechanism to the drill barrel, which is located near the lower end of the drill barrel. The elastic rod blocking mechanism has an inlet for the boulders to pass through. In this way, when the drill barrel encounters a boulder, the drill barrel applies pressure to the boulder, and the boulder enters the drill barrel cavity through the inlet of the elastic rod blocking mechanism at the drill barrel opening. During the drilling process, the elastic rod blocking mechanism blocks the boulder, preventing it from falling, thereby pulling the boulder out of the borehole together. Compared with the prior art, this utility model can effectively handle boulders in the borehole and improve the drilling efficiency.
