Description

TECHNICAL FIELD

[0001] The utility model relates to a goaf surveying drill convenient to install. BACKGROUND

[0002] Goaf is a "cavity" formed under the ground surface due to human excavation or natural geological movement. In many engineering fields, especially before the construction of infrastructure such as highways, it is crucial to accurately detect goaf. Because the existence of goaf can cause a series of geological disasters, such as pillar deformation, rock movement, and surface subsidence, etc. Once these disasters occur, especially the sudden collapse of the goaf, it will cause serious personnel casualties and equipment damage, and thus have a great negative impact on the construction of the highway.

[0003] In the process of goaf detection, a surveying drill is usually used to drill on the ground surface of the goaf. The principle is to compare the actual drill rod descent rate with the standard drill rod descent rate to determine whether the area is a goaf. However, the current surveying drill has a big operation problem when installing the drill rod.

[0004] The existing surveying drill is mostly an impact sampling drill machine. When installing the drill rod, the impact rod needs to impact the drill rod back and forth for sampling operation. In this process, due to the impact force of the impact rod, the drill rod is prone to tilt. In order to ensure that the drill rod can stand stably on the ground and ensure the smooth drilling operation, a worker needs to specially hold the drill rod. This way of manually holding the drill rod not only increases the labor intensity of the worker, but also requires additional labor cost in the whole process of goaf detection. In large-scale goaf detection or time-critical projects, this problem is particularly prominent, which seriously affects the work efficiency of goaf detection.

[0005] Based on the defects of the above-mentioned prior art, it is necessary to develop a goaf surveying drill convenient to install, which aims to solve the problem that a worker needs to specially hold the drill rod when installing the drill rod of the surveying drill, reduce the labor input in the process of goaf detection, and improve the efficiency and safety of goaf detection work. CONTENT OF THE UTILITY MODEL

First, the connecting ring is connected on the outside of the drill rod, and the roller in its inside is attached to the drill rod, reduces the friction between the drill rod and the connecting ring, guarantees that the connecting ring can play a certain limiting effect to the drill rod. The upper side of the connecting ring has the butt joint groove, and the butt joint block is butted, and the butt joint block side is welded the connecting seat, and the limiting bolt is passed through in the connecting seat, and the limiting bolt is connected with the limiting slot of the one side of the connecting seat with the thread. This connecting mode makes the connecting seat and the connecting ring closely connected. The connecting rod welded on the lower side of the connecting seat is slidably butted with the butt joint pipe, and the first spring in the butt joint pipe is fixed with the connecting rod and the butt joint pipe respectively. When the drill rod is inserted into the connecting ring, the butt joint pipe is erected on the ground, and when the impact rod impacts the drill rod back and forth under the drive assembly, the connecting ring is supported under the butt joint pipe, and the above-mentioned connecting structure provides stable support force for the drill rod. With the drill rod gradually inserted into the ground, the connecting rod can slide in the butt joint pipe, and the first spring can adaptively adjust the support force, guarantees that the drill rod is always provided with effective support in a certain range.

[0017] The utility model discloses the beneficial effect is:

[0018] 1. In the goaf detection operation, aiming at the problem that the existing surveying drill needs manual support when installing the drill rod, the specific structure of the surveying drill is adopted. First, the support is erected on the ground, the butt joint block is butt jointed with the butt joint groove, then the limiting bolt is butt jointed with the limiting groove and the limiting bolt is rotated, the connecting rod and the butt joint pipe are connected with the connecting ring, and then the butt joint pipe is erected on the ground, and the drill rod is inserted into the connecting ring. After starting the driving assembly, the connecting ring supports the drill rod under the support of the butt joint pipe, without the need for workers to support the drill rod, and through the cooperation of the connecting rod, the butt joint pipe and the connecting ring, the function is realized, which greatly improves the convenience of the drill rod installation in the goaf detection. Since the manual support operation of the drill rod is omitted, the labor input is reduced, the process of the surveying drill in the goaf detection is more efficient, and the overall progress of the goaf detection is accelerated.

[0019] 2. When the surveying drill is placed on the surface of the goaf detection area for drill rod installation, the upper limiting frame is separated from the clamping groove by pulling up, and the anti-skid block is placed on one side of the displacement wheel, so that the surveying drill can be effectively prevented from sliding during the installation of the drill rod. This design ensures the stability and safety of the drill rod installation operation, avoids operation errors or equipment damage caused by the sliding of the surveying drill.

[0034] The specific operation process of the goaf survey drill convenient to install:

[0035] I. Drill rod installation and support operation

[0036] Preparation and connection: In view of the geological disasters such as deformation of ore pillar, rock movement and surface subsidence caused by goaf, and the potential impact on highway construction, it is necessary to use the survey drill to detect the goaf in the relevant area. First, the support 12 is firmly erected on the ground, and then the assembly of the connecting ring 2 related parts is carried out. The butt joint block 23 is butt jointed with the butt joint groove 22, since the cross-sectional size of the butt joint groove 22 matches the cross-sectional size of the butt joint block 23, the limiting bolt 25 can be conveniently positioned and butt jointed with the limiting groove 26. Then the limiting bolt 25 is butt jointed with the limiting groove 26, and the limiting bolt 25 is rotated, since the limiting bolt 25 is in threaded connection with the limiting groove 26, so that the limiting bolt 25 and the limiting groove 26 are tightly limited together, thereby realizing the stable connection of the connecting rod 27 and the butt joint pipe 28 with the connecting ring 2.

[0037] Drill rod installation and impact: then the butt joint pipe 28 is erected on the ground, the drill rod 15 is inserted into the connecting ring 2, at this time the roller 21 is in close contact with the surface of the drill rod 15. Start the driving assembly 1, the driving assembly 1 drives the traction rope 13 to move repeatedly, the traction rope 13 drives the impact rod 14 to impact the drill rod 15 back and forth. In this process, the connecting ring 2 effectively supports the drill rod 15 under the action of the butt joint pipe 28, without the need for workers to specially hold the drill rod 15, greatly facilitating the drill rod installation operation. As the drill rod 15 gradually extends into the bottom surface, the connecting rod 27 will be received into the bottom inside of the butt joint pipe 28, when the drill rod 15 is deepened to a certain degree without additional support, rotate the limiting bolt 25 to make the limiting bolt 25 separate from the limiting groove 26, then the connecting rod 27 and the butt joint pipe 28 can be taken off from the connecting ring 2, then continue to impact the drill rod 15 until the drill rod 15 is completely inserted into the underground for detection operation. Through the cooperation of the connecting rod 27 and the butt joint pipe 28 with the connecting ring 2, the convenient installation of the drill rod 15 of the survey drill when detecting the goaf is successfully realized.

[0038] II. Use and storage of the anti-skid block

[0039] The anti-skid block is enabled: the bottom plate of the driving assembly 1 is provided with a storage slot 3, and an anti-skid block 4 is arranged inside. The anti-skid block 4 has a clamping groove 5 on the upper side. The bottom plate is provided with a placement slot 6 above the clamping groove 5. A limiting frame 7 penetrates the placement slot 6. The limiting frame 7 is in abutment with the clamping groove 5. The placement slot 6 has a second spring 8, the two ends of which are respectively sleeved with the placement slot 6 and the limiting frame 7. The inner wall spacing of the storage slot 3 matches the thickness of the anti-skid block 4, and the inner wall spacing of the clamping groove 5 matches the diameter of the limiting frame 7. When the survey drill is placed on the surface of the goaf detection area, in order to prevent the survey drill from sliding when the drill rod 15 is installed, the limiting frame 7 is pulled upward to make it disengage from the clamping groove 5. At this time, the anti-skid block 4 can be pulled out of the storage slot 3 and placed on one side of the displacement wheel 11, effectively preventing the survey drill from sliding.

[0040] Storage of the anti-skid block: when the use of the anti-skid block 4 is finished, the limiting frame 7 is pulled up again, the anti-skid block 4 is completely inserted into the storage slot 3, and then the limiting frame 7 is released. At this time, the lower end of the limiting frame 7 is in abutment with the clamping groove 5 under the action of the second spring 8, so that the anti-skid block 4 is limited inside the storage slot 3. This design of storing the anti-skid block 4 inside the survey drill greatly facilitates the use of the anti-skid block 4 to prevent the survey drill from sliding during operation, and is convenient for management and storage of the anti-skid block 4, improving the convenience and integrity of equipment use.

[0041] In summary, the goaf survey drill convenient to install is designed for the detection needs of the goaf. Through the unique drill rod installation support structure and the ingenious design of the anti-skid block, the problems of manual support during drill rod installation and easy sliding of the survey drill in traditional survey drills are effectively solved, improving the efficiency and safety of goaf detection work. The contents not described in detail belong to the existing technology known to those skilled in the art.
