Description

Technical Field

[0001] This utility model relates to the field of drilling machine technology, specifically a clamping device applied to a drilling mechanism. Background Technology

[0002] In engineering fields such as mining and tunneling, drilling is a crucial process, and the stability of the drilling mechanism directly affects drilling accuracy and operational efficiency.

[0003] During operation, traditional drilling equipment is prone to displacement and shaking of the drilling mechanism due to problems such as equipment vibration and uneven force, which seriously affects the drilling quality and may even cause safety accidents.

[0004] Patent CN206801455U discloses a mining equipment including a drilling mechanism head connected to a turntable. The turntable has hydraulic cylinders, the outer ends of which are supported and connected to the drilling mechanism head. The turntable is fixed to a support arm, which is hinged to a traveling mechanism. The traveling mechanism has a second hydraulic cylinder, the outer end of which is supported and connected to the support arm. The traveling mechanism is a loader body. A pressure bearing is located inside the turntable. This design features a simple structure, free rotation, and greater adaptability.

[0005] The aforementioned mining equipment still lacks sufficient stability in ensuring the overall stability of the drilling mechanism during operation. It relies solely on components such as hydraulic cylinders for support and connection. When faced with complex geological conditions or large reaction forces during drilling, it is difficult to effectively prevent the equipment from shifting and shaking, thereby affecting the accuracy and quality of drilling. Furthermore, during long-term continuous operation, the lack of a reliable clamping device will lead to accelerated wear between the various components of the equipment, reducing the service life of the equipment. Utility Model Content

[0006] The purpose of this utility model is to provide a clamping device for drilling mechanisms to solve the technical problems of existing equipment that rely solely on hydraulic cylinder support, lack reliable clamping structures, are prone to displacement and shaking under complex geological operations or when subjected to large reaction forces, resulting in decreased drilling accuracy and quality, and accelerated wear and shortened service life of equipment components under long-term continuous operation.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A clamping device for a drilling mechanism is provided. The clamping device is located at the lower end of the drilling mechanism. The clamping device includes a horizontal plate fixedly connected to the lower surface of the housing of the drilling mechanism. Guide cylinders are symmetrically arranged at both ends of the upper surface of the horizontal plate. A clamping mechanism is slidably installed in the guide cylinders. The clamping mechanism is arranged at both ends of the outer surface of the housing of the drilling mechanism, and the lower surface of the clamping mechanism can penetrate from the middle of the two sets of guide cylinders to the lower end of the horizontal plate.

[0008] The clamping mechanism includes two sets of U-shaped frames, which are fixedly installed at both ends of the housing of the drilling mechanism. Hydraulic rods are rotatably installed inside each set of U-shaped frames. A bearing plate is fixedly installed between the piston rods of the two sets of hydraulic rods. Two sets of connecting cylinders are connected to the upper surface of the bearing plate. Threaded nails are threaded into each of the two sets of connecting cylinders, so that the nail heads can be threaded through the lower surface of the connecting cylinder and clamped to the ground.

[0009] As a preferred embodiment of this utility model, guide wheels are rotatably installed at both ends of the two sets of guide rail cylinders arranged opposite to each other, and the guide wheels at both ends of each set of guide rail cylinders abut against the two ends of the clamping mechanism that slides through them.

[0010] As a further embodiment of this utility model, guide rail plates are fixedly installed at both ends of the upper surface of the bearing plate, and the guide rail plates slide through the cross plate and are slidably installed inside the guide rail cylinder.

[0011] As a further embodiment of this utility model, both ends of the guide rail plate are provided with embedded guide rail grooves, which are used for the guide wheel to fit and roll within.

[0012] As a preferred embodiment of this utility model, the two sets of guide rail plates sliding inside the guide rail cylinder simultaneously cover one end of the outer surface of the two sets of hydraulic rods.

[0013] Compared with the prior art, the beneficial effects of the clamping device of this utility model applied to the drilling mechanism are as follows: This invention utilizes the coordinated action of hydraulic rod drive and threaded nail clamping, combined with the stable guiding structure of guide rail plate, guide rail cylinder and guide wheel, to provide reliable and stable support for the drilling mechanism, effectively offsetting vibration and reaction force during drilling and ensuring drilling accuracy. Furthermore, the hydraulic drive enables convenient clamping and resetting operations, reducing preparation and finishing time before and after operation. Simultaneously, the guide rail plate protects the hydraulic rod, and the guide wheel reduces frictional resistance, minimizing component wear and extending equipment lifespan. Overall, this invention improves the stability, efficiency and economy of drilling operations. Attached Figure Description

[0020] See Figure 1 As shown in the figure, an embodiment of the present invention provides a clamping device for a drilling mechanism. The clamping device is located at the lower end of the drilling mechanism and includes a horizontal plate 101 fixedly connected to the lower surface of the housing of the drilling mechanism. Guide rail cylinders 102 are symmetrically fixedly installed at both ends of the upper surface of the horizontal plate 101. A clamping mechanism 2 is slidably installed inside the guide rail cylinders 102. The clamping mechanism 2 is disposed at both ends of the outer surface of the housing of the drilling mechanism 1, and the lower surface of the clamping mechanism 2 can penetrate from the middle of the two sets of guide rail cylinders 102 to the lower end of the horizontal plate 101.

[0021] Two sets of guide rail cylinders 102 arranged opposite to each other are rotatably mounted with guide wheels 103 at both ends, and the guide wheels 103 at both ends of each set of guide rail cylinders 102 abut against the two ends of the clamping mechanism 2 that slides through them.

[0022] When the clamping device is in use, the horizontal plate 101 fixedly connected to the lower surface of the drilling mechanism 1 housing remains stable with the drilling mechanism 1, while the guide rail cylinders 102, which are fixed at both ends of the upper surface of the horizontal plate 101, are in a preset position. When the clamping mechanism 2 moves downward, since the clamping mechanism 2 is slidably installed inside the guide rail cylinder 102, it will move along the internal channel of the guide rail cylinder 102 during its downward movement. At the same time, the guide wheels 103, which are rotatably installed at both ends inside the guide rail cylinder 102, will always contact the two ends of the clamping mechanism 2. At the same time, the guide wheel 103 rotates accordingly, thereby reducing the sliding friction resistance between the clamping mechanism 2 and the guide rail cylinder 102, ensuring that the clamping mechanism 2 can move downward smoothly and stably. As the clamping mechanism 2 continues to move downward, its lower surface gradually penetrates from the middle of the two sets of guide rail cylinders 102 to the lower end of the horizontal plate 101 to form a stable support. Then, the stabilizing force is transmitted to the drilling mechanism 1 through the guide rail cylinder 102 and the horizontal plate 101, so that the drilling mechanism 1 remains stable throughout the drilling operation and effectively avoids displacement of the drilling mechanism 1.

[0023] like Figures 2-3 As shown, the clamping mechanism 2 includes two sets of U-shaped frames 205. The two sets of U-shaped frames 205 are respectively fixedly installed at both ends of the housing of the drilling mechanism 1. Hydraulic rods 207 are rotatably installed inside the two sets of U-shaped frames 205. A bearing plate 201 is fixedly installed between the piston rods of the two sets of hydraulic rods 207. Two sets of connecting cylinders 202 are connected and installed on the upper surface of the bearing plate 201. Threaded nails 203 are threadedly installed inside the two sets of connecting cylinders 202, so that the nail head of the threaded nail 203 can be threaded out from the lower surface of the connecting cylinder 202.

[0024] Guide rail plates 204 are fixedly installed at both ends of the upper surface of the bearing plate 201. The guide rail plates 204 slide through the horizontal plate 101 and are slidably installed in the guide rail cylinder 102. Both ends of the guide rail plates 204 are embedded with guide rail grooves 206, which are used for the guide wheels 103 to fit and roll. The two sets of guide rail plates 204 sliding in the guide rail cylinder 102 simultaneously cover one end of the outer surface of the two sets of hydraulic rods 207.

[0025] The hydraulic rod 207, fixed within the U-shaped brackets 205 at both ends of the drilling mechanism 1 housing, is activated. The piston rod of the hydraulic rod 207 extends and pushes the bearing plate 201 downward. The guide rail plates 204 at both ends of the upper surface of the bearing plate 201 slide along the guide rail cylinder 102. Since the guide rail plates 204 cover one end of the outer surface of the hydraulic rod 207, they can guide and protect the extension and retraction of the hydraulic rod 207. At the same time, the guide rail grooves 206 embedded at both ends of the guide rail plates 204 engage with the guide wheels 103 inside the guide rail cylinder 102. The guide wheels 103 roll within the guide rail grooves 206, further reducing the frictional resistance when the guide rail plates 204 slide, ensuring that the bearing plate 201 moves downward smoothly. When the bearing plate 201 drives the connecting cylinder 202 downward, the connecting cylinder 202 can drive the threaded pins 203 installed internally. With the top firmly on the ground, the hydraulic rod 207 remains extended. Combined with the tightening action of the threaded nail 203, the stabilizing force is sequentially transmitted to the guide cylinder 102 and the horizontal plate 101 via the bearing plate 201 and guide rail plate 204. This provides stable support for the drilling mechanism 1, effectively counteracting vibrations and reaction forces during drilling, preventing displacement and swaying of the drilling mechanism 1, significantly improving drilling accuracy and work quality, and reducing rework or safety hazards caused by equipment instability. After drilling is completed, the piston rod of the hydraulic rod 207 can be controlled to retract, causing the bearing plate 201 and guide rail plate 204 to return to their original positions along the guide cylinder 102. The guide groove 206 and guide wheel 103 work together again to ensure a smooth resetting process until the guide plate 204 and bearing plate 201 return to their initial positions, completing the retraction of the tightening mechanism 2.

[0026] The working steps of the above technical solution are as follows: The drilling rig is moved to a designated position, aligning the drilling mechanism 1 with the preset area. At this time, the horizontal plate 101, fixedly connected to the lower surface of the drilling mechanism 1 housing, remains stable with the drilling mechanism 1. The guide rail cylinders 102, whose two ends are relatively fixed on the upper surface of the horizontal plate 101, are also in the preset working position. The hydraulic rod 207, rotatably connected to both ends of the outer surface of the drilling mechanism 1 housing, is activated. After the hydraulic rod 207 is activated, its piston rod extends and pushes the bearing plate 201 downwards. The guide rail plates 204 at both ends of the upper surface of the bearing plate 201 slide along the guide rail cylinder 102. Because the guide rail plates 204 cover one end of the outer surface of the hydraulic rod 207, they can guide and protect the extension and retraction of the hydraulic rod 207. Simultaneously, the guide rail grooves 206 embedded at both ends of the guide rail plates 204 engage with the guide wheels 103 inside the guide rail cylinder 102. The guide wheels 103 roll within the guide rail grooves 206, further... The frictional resistance of the guide rail plate 204 during sliding is reduced to ensure the smooth downward movement of the bearing plate 201. When the bearing plate 201 drives the connecting cylinder 202 to move down to near the ground, the connecting cylinder 202 can drive the threaded nail 203 installed internally to press against the ground. At this time, the hydraulic rod 207 remains extended. With the pressing action of the threaded nail 203, the stabilizing force is transmitted sequentially to the guide cylinder 102 and the horizontal plate 101 through the bearing plate 201 and the guide rail plate 204. Finally, the drilling mechanism 1 obtains stable support and effectively counteracts the vibration and reaction force during drilling. After the drilling operation is completed, the piston rod of the hydraulic rod 207 can be controlled to retract, driving the bearing plate 201 and the guide rail plate 204 to reset upward along the guide cylinder 102. The guide groove 206 and the guide wheel 103 cooperate again to ensure the smooth reset process until the guide plate 204 and the bearing plate 201 return to the initial position, completing the retraction of the pressing mechanism 2.

[0027] In summary, this utility model embodiment provides a stable force support for the drilling mechanism 1 through a dual support structure of hydraulic drive and top clamping support, effectively offsetting the vibration and rock reaction force during drilling, preventing displacement and shaking of the drilling mechanism 1, ensuring that the drill bit is always accurately aligned with the area to be drilled, reducing drilling deviation, and improving drilling quality.

The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. The above embodiments and descriptions in the specification are only illustrative of the principles of the present invention. Any modifications, equivalent substitutions, and improvements made within the scope of the present invention without departing from the scope of the present invention should be included within the protection scope of the present invention.
