Description

Technical Field

[0001] This utility model relates to the field of coring drill technology, and in particular to a coring drill machine that is easy to adjust. Background Technology

[0002] A core drilling rig is an engineering device specifically designed for drilling cylindrical rock cores, concrete cores, or other material samples. It is widely used in geological exploration, construction, mining, and scientific research. Its easily adjustable design significantly improves operational efficiency, adaptability, and safety in practical applications, offering particularly strong advantages in complex and variable working environments.

[0003] However, when using common coring rigs on uneven or irregular surfaces, the equipment height and angle are fixed, requiring workers to apply more force during operation. If the equipment suddenly sways excessively, and the uneven ground provides no stable foothold for workers, safety issues can arise. Furthermore, in complex areas inaccessible by vehicles, workers must manually carry drill rods to the work site. However, standard drill rods are quite long, making transport extremely inconvenient. During transport, the complex terrain can cause objects to sway and collide with other workers, and slippery, uneven ground can lead to falls and injuries as workers cannot quickly brace themselves with their hands.

[0004] Therefore, this application provides an easily adjustable coring drill to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an easily adjustable core drilling rig that can adapt to more complex terrains and shorten the drill rod length without affecting operations.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An easily adjustable core drilling rig includes a drive unit, three support units, and a core drilling device. The drive unit includes a drive housing with a drive hole on the lower end face. An electric telescopic rod is fixedly installed on the top surface inside the drive hole. A fixing block is fixedly connected to the output end of the electric telescopic rod, and a motor body is fixedly installed at the lower end of the fixing block.

[0008] All three support devices include a mast and a support plate. Each section of the mast is fixedly connected to a screw locking ring at its upper end, and a conical nail is fixedly installed at each of the four corners of the lower end face of the support plate.

[0009] The core sampling device includes a connecting drill rod and a drill bit rod. Both the upper end of the outer wall of the connecting drill rod and the upper end of the drill bit rod are fixedly provided with connectors. The lower end of the outer wall of the connecting drill rod and the output end of the motor body are both fixedly provided with connecting seats. A hollow drill is fixedly provided at the lower end of the outer wall of the drill bit rod.

[0010] Furthermore, the three sides of the outer wall of the drive housing are all hinged to the mast via pins.

[0011] Furthermore, the upper surface of the drive housing has a hole for storing batteries and a battery block is fixedly installed inside.

[0012] Furthermore, the connector is slidably disposed inside the connector seat and is fixedly connected by two screws.

[0013] Furthermore, the inner wall of the drive hole is provided with three slide rails, and the outer wall of the motor body is fixedly provided with three sliders, which are respectively slidably disposed inside the three slide rails.

[0014] Furthermore, the upper and lower ends of the drive housing are respectively fixedly connected to the battery cover and the motor cover by multiple bolts.

[0015] Furthermore, the lower end of the mast is hinged to the support plate via a pin.

[0016] This utility model has the following beneficial effects:

[0017] 1. The present invention proposes an easily adjustable core drilling machine. The drill rod of the machine is spliced, and multiple connecting drill rods can be fixedly connected to the connecting seat through the connector. Each connecting drill rod is not very long, so it is not difficult to carry manually when it is not possible to transport it outdoors by car. This can avoid the problem of impact caused by excessive length during transportation or the inability to quickly put down the drill rod and support the ground with both hands when it falls.

[0018] 2. This utility model proposes an easily adjustable core drilling rig. Supported by a height-adjustable support device, the mast height can be adjusted by loosening the locking rings on the outer wall of the mast and then tightening the locking rings once the target height is reached. The combination of the support plate and the conical nail allows it to adapt to more uneven surfaces and prevents collapse and slippage, effectively preventing excessive equipment sway.

[0028] 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.

[0029] Reference Figure 1 , Figure 3 This utility model provides an embodiment of an easily adjustable core drilling rig, comprising a drive device 1, three support devices 2, and a core drilling device 3. The drive device 1 includes a drive housing 101, a drive hole 107 on the lower end face of the drive housing 101, an electric telescopic rod 102 fixedly mounted on the top surface of the drive hole 107, a fixed block fixedly connected to the output end of the electric telescopic rod 102, and a motor body 104 fixedly mounted on the lower end of the fixed block. The three sides of the outer wall of the drive housing 101 are hinged to the mast 201 by pins. The upper end face of the drive housing 101 has a hole for storing batteries, and a battery block 106 is fixedly mounted inside. The inner wall of the drive hole 107 has three slide rails 103. The outer wall of the motor body 104 is fixedly mounted with three sliders 105, which are slidably mounted inside the three slide rails 103 respectively. The upper and lower ends of the drive housing 101 are fixedly connected to a battery cover and a motor cover by multiple bolts respectively.

[0030] Specifically, through the sliding engagement of slider 105 and slide rail 103, the motor body 104 inside the drive hole 107 is only affected by the up-and-down drive of electric telescopic rod 102, and will not rotate internally due to its own generated torque. With the assistance of battery block 106, it can operate outdoors without a power cord.

[0031] Reference Figure 2 , Figure 4 The three support devices 2 include a mast 201 and a support plate 203. Each section of the mast 201 is fixedly connected to a screw locking ring 202 at its upper end. Conical nails 204 are fixedly installed at the four corners of the lower end face of the support plate 203. The lower end of the mast 201 is hinged to the support plate 203 by a pin.

[0032] Specifically, the height of the support device 2 can be freely controlled by the cooperation between the mast 201 and the screw locking ring 202. The support plate 203 can increase the contact area, thereby providing better support and preventing collapse. And multiple conical nails 204 inserted into the bottom surface can firmly grip the ground and prevent slippage.

[0033] Reference Figure 5 , Figure 6 , Figure 7 The core sampling device 3 includes a connecting drill rod 301 and a drill bit rod 304. Connecting heads 302 are fixedly provided on the upper ends of the outer walls of both the connecting drill rod 301 and the drill bit rod 304. Connecting seats 303 are fixedly provided on the lower ends of the outer walls of the connecting drill rod 301 and the output end of the motor body 104. A hollow drill 305 is fixedly provided on the lower ends of the outer walls of the drill bit rod 304. The connecting head 302 is slidably disposed inside the connecting seat 303 and is fixedly connected by two screws.

[0034] Specifically, multiple connecting drill rods 301 can be fixedly connected by connecting heads 302 and connecting seats 303, and can be assembled according to the target length.

[0035] Working Principle: The drill rod of this equipment is modular and can be spliced ​​to achieve the required length, making it easier to transport outdoors. When transporting the equipment to the work site, the height of the support device 2 can be adjusted according to the terrain. If it is a slope, the mast 201 on the steeper side can be shortened, and the mast 201 on the gentler side can be extended, so that the drive device 1 is parallel to the horizontal line. Then, the multiple screw locking rings 202 on the outer wall of the mast 201 are tightened. The support plate 203 can distribute the force and better support to prevent collapse. The conical nails 204 at the lower end of the support plate 203 can firmly grip the bottom surface to prevent slippage, so that it can remain stable even on uneven and irregular ground surfaces, effectively preventing excessive swing of the equipment. When sampling is required, first insert the connector 302 of the connecting drill rod 301 into the connecting seat 303 of the motor body 104 and secure it with two screws. Then, insert the connector 302 of the drill bit 304 into the connecting seat 303 of the connecting drill rod 301 and secure it with two screws. Multiple connecting drill rods 301 can be connected between the output end of the motor body 104 and the drill bit 304 using this connection method until the desired length is reached. Operating the switch at the top of the drive device 1 releases electrical energy from the battery block 106, activating the motor body 104 to drive the core sampling device 3 for sampling. The battery block 106 is a mature and publicly available technology; therefore, its specific structure and working principle will not be described in detail here.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
