Description

Technical Field

[0001] This utility model relates to the field of engineering geological core drilling, specifically to a lifting device for a geological exploration core drilling rig. Background Technology

[0002] Geological exploration coring drills are key equipment for obtaining underground rock core samples, which are crucial for resource assessment and geological research. When using geological exploration coring drills, a lifting device is typically used, which is connected to the drill pipe to allow for the staged lifting of the drill pipe.

[0003] like Figure 1 As shown, the existing hoist includes a body a and a collar b. The body a has a locking structure a1. The drill spindle c engages with the locking structure a1 via a notch c1 and is quickly locked using the collar b. In some stages of use, when it is necessary to separate the hoist from the drill spindle, the hoist will lift the spindle to a high height, exposing one end of the drill rod. Separating the hoist from the spindle requires workers to climb onto the drill rig's climbing frame or stand on the equipment for manual operation. Specifically, this involves manually raising the collar and pushing the drill spindle away from the locking structure. This method carries the risk of workers slipping or falling from the climbing frame. Utility Model Content

[0004] To at least partially address the shortcomings of the existing technology, the main objective of this utility model is to provide a lifting device for geological exploration core drilling rigs that can separate the drilling rig spindle and the lifting device without requiring workers to climb to heights, thus offering advantages such as high practicality and low safety risk.

[0005] To achieve the aforementioned main objectives, this utility model discloses a lifting device for a geological exploration core drilling rig, comprising a body and a collar. The collar is slidably fitted onto the outer circumferential wall of the body. The body has a lateral disassembly port, through which the drilling rig spindle is installed into the body and limited by the collar. A mounting plate and an electric push rod vertically mounted on the mounting plate are provided on the first side of the body. The movable end of the electric push rod is connected to the collar to drive the collar to perform lifting and lowering movements. An L-shaped frame and a rotating push frame are provided on the second side of the body. The rotating push frame is hook-shaped and has a first push frame plate and a second push frame plate connected to each other. The first push frame plate is mounted to the… On the L-shaped frame, in the vertical direction, the free end of the second pusher plate is located below the free end of the first pusher plate. In the horizontal direction, the free end of the second pusher plate is located on the side away from the free end of the first pusher plate. There is a gap between the free end of the second pusher plate and the body to allow the collar to pass through and abut against the free end of the first pusher plate. The body is provided with a clearance opening corresponding to the second pusher plate. When the collar is lifted by the electric push rod, it abuts against the free end of the first pusher plate and drives the rotating pusher to rotate. Simultaneously, it drives the free end of the second pusher plate to rotate and insert into the body through the clearance opening, so as to push the drilling rig spindle outward from the side disassembly port.

[0006] According to one specific embodiment of this utility model, a torsion spring is fitted onto the rotating shaft.

[0007] According to a specific embodiment of the present invention, the first pusher plate is straight and the second pusher plate is curved.

[0008] According to a specific embodiment of this utility model, the collar is provided with a connecting block that protrudes laterally, and the movable end of the electric push rod is fixedly connected to the connecting block.

[0009] Furthermore, the connecting block is a metal block, the collar is a metal collar, and the connecting block and the collar are welded together.

[0010] Furthermore, the connecting block is connected to the collar via a flexible bracket on it.

[0011] According to a specific embodiment of the present invention, it also includes a connecting cable, through which the electric push rod is electrically connected to the drilling rig power supply equipment.

[0012] This utility model has the following advantages: It provides a lifting device for a geological exploration core drilling rig. By setting an electric push rod to drive the collar to automatically lift and lower, the first push plate of the rotating push frame and the lifting collar are linked to lift and lower, thereby driving the second push plate frame into the device body and pushing the drilling rig spindle outward from the side disassembly port. Finally, the drilling rig spindle and the lifting device are automatically separated. The whole process can be achieved without workers having to climb to heights. It has the advantages of strong practicality and low safety risk.

[0020] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Many specific details are set forth in the following description in conjunction with embodiments in order to provide a full understanding of the present invention. However, it should be understood that the following embodiments and detailed description are for illustrative purposes only and do not limit the scope of protection of the present invention.

[0022] The example of the lifting device for geological exploration core drilling rigs, such as Figure 2 As shown, it includes a body 10, a collar 20, a mounting plate 30, an electric push rod 40, an L-shaped frame 50, and a rotating push frame 60; wherein, the collar 20 is specifically slidably fitted on the outer circumference of the body 10, and the body 10 has a lateral disassembly port 11, through which the drilling rig spindle is installed into the body 10 and limited by the collar 20.

[0023] Mounting plate 30 is located on the first side (specifically the left side) of the device body 10. Electric push rod 40 is vertically mounted to mounting plate 30. The movable end of electric push rod 40 is connected to collar 20 to drive collar 20 to perform lifting and lowering actions. The stroke of electric push rod 40 can be selected as needed, for example, 40cm or 50cm. Its structure and principle can be learned by those skilled in the art through technical manuals.

[0024] Specifically, the electric actuator 40 can be powered by a connecting cable (not shown in the figure) connected to the drilling rig control equipment. The connecting cable, for example, is a spiral cable, which can be wound around the climbing frame or other locations that do not obstruct normal construction. Furthermore, the outer layer of the connecting cable is wrapped with wear-resistant insulating material to effectively prevent damage to the wiring caused by friction or rainwater erosion, while also possessing a certain degree of elasticity to avoid pulling. Those skilled in the art can make other corresponding settings according to actual needs, which will not be elaborated upon here. During use, for example, the extension and retraction of the electric actuator 40 are controlled by a control switch electrically connected to the connecting cable. The control switch is located in a position easily accessible to the worker, and its installation can be selected and chosen according to needs.

[0025] like Figure 2-3 As shown, the L-shaped frame 50 is located on the second side (specifically the right side) of the body 10, and the rotating pusher 60 is installed on the L-shaped frame 50; wherein, the rotating pusher 60 is hook-shaped, and has a first pusher plate 61 and a second pusher plate 62 connected to each other, and the first pusher plate 61 and the second pusher plate 62 are preferably integrally formed metal frames.

[0026] The first push plate 61 is preferably straight, and the second push plate 62 is preferably curved, specifically a downwardly extending curved plate. The first push plate 61 is mounted on the L-shaped frame 50 via a rotating shaft 63. In the vertical direction, the free end 621 of the second push plate is located below the free end 611 of the first push plate. In the horizontal direction, the free end 621 of the second push plate is located to the side of the free end 611 of the first push plate, away from the body 10. A gap exists between the free end 621 of the second push plate and the body 10 to allow the collar 20 to pass through and abut against the free end 611 of the first push plate. Correspondingly, the free end of the first push plate 61 will not contact the outer wall of the body 10 during rotation and can rotate freely.

[0027] The body 10 is provided with a clearance opening 12 corresponding to the second pusher plate 62. When the collar 20 is lifted by the electric push rod 40, it abuts against the free end 611 of the first pusher plate and drives the rotating pusher 60 to rotate. Simultaneously, it drives the free end 621 of the second pusher plate to rotate and insert into the body 10 through the clearance opening 12, so as to push the drilling rig spindle A outward from the side disassembly opening 11. Figure 4 As shown. It should be noted that the action of pushing the drill spindle A outward from the side disassembly port 11 by the contact between the free end 621 of the second push plate and the drill spindle A is bidirectional, that is, the drill spindle A can be stationary while the body 10 itself moves laterally.

[0028] Please continue reading. Figure 3A torsion spring 64 is fitted onto the rotating shaft 63. The torsion spring 64 is used to keep the rotating pusher 60 in its current initial shape and to actively reset the rotating pusher 60 using elastic potential energy after the collar 20 descends. In other embodiments, the automatic reset of the rotating pusher 60 can also be achieved by adding, for example, a limiting post in conjunction with the gravity of the rotating pusher 60 itself.

[0029] The collar 20 in this embodiment specifically adopts a metal collar from the prior art; please refer again to [the previous text]. Figure 2 To achieve the connection between the movable end of the electric push rod 40 and the collar 20, in this embodiment, the collar 20 is provided with a connecting block 21 that protrudes laterally (to the left). The connecting block 21 is welded to the collar 20, and the movable end of the electric push rod 40 is fixedly connected to the connecting block 21. In other embodiments, to directly adapt to existing collars 20, other methods such as snap-fit ​​or bolt connections can be used to achieve a detachable connection between the connecting block 21 and the collar 20, for example... Figure 5 In the modified example shown, the connecting block 21 is connected to the collar 20 by a snap-fit ​​connection via the elastic bracket 22 on it.

[0030] like Figure 6 As shown, in use, the hoist is lifted as a whole by the steel cable traction drive mechanism 70. During normal use of the equipment, workers can achieve active separation between the drilling rig spindle A and the hoist without climbing the ladder 80. The structure is compact and highly practical, and it can also significantly reduce the safety risks at the construction site.

[0031] Although the present invention has been described above through embodiments, the above embodiments are only used to exemplarily describe possible implementations of the present invention, and are not intended to limit the scope of protection of the present invention. Any equivalent substitutions or changes made by those skilled in the art in accordance with the present invention should also be covered by the scope of protection defined by the claims of the present invention.
