Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of loading and unloading a drilling and coring machine, in particular to a device that facilitates loading and unloading a drilling and coring machine. Background Art
[0002] A core drilling machine is a specialized device used to extract cylindrical core samples from various building materials or geological samples. Structurally, it consists mainly of a power system, drilling tools, and a frame. The power system is its core power source and is generally an electric motor, which provides strong power for the rotation of the drill bit to ensure smooth cutting into the material. The drilling tool consists of a drill bit and a drill rod. The material and design of the drill bit vary depending on the coring object. For example, when coring concrete structures, the drill bit used has high hardness and wear resistance, and can effectively penetrate hard concrete. When coring softer geological materials, the drill bit design focuses more on maintaining the integrity of the core sample. The frame plays a supporting and stabilizing role, ensuring that the equipment does not shake during the coring process, thereby improving the accuracy of coring.
[0003] The purpose of this device is to facilitate the convenient, safe, and efficient transfer of coring machines between vehicles and sites. This is necessary due to the bulkiness of the equipment, the need for improved efficiency, and the need to ensure equipment safety. Existing technologies primarily handle the loading and unloading of coring machines through forklifts using bottom grooves or reserved spaces, rollers and guide rails using friction, and lifting equipment using lifting points and cranes. Each method has its own applicable scenarios and key points, collectively serving the loading and unloading needs of coring machines.
[0004] However, some existing devices for loading and unloading coring machines are unable to securely clamp the coring machine. Once loaded onto a transport vehicle, the large and heavy machine body cannot be reliably restrained. When traveling on roads with poor road conditions, the coring machine is easily displaced by the vehicle's shaking, braking, and acceleration. The machine can slide back and forth within the vehicle, colliding violently with the vehicle walls and causing dents, scratches, and even cracks to the outer shell. Therefore, to address these shortcomings, a device for loading and unloading coring machines is proposed to address these issues. Utility Model Content

This effectively cushions the downward force of the core driller passing through the rotating door when it is unloaded, preventing damage from collisions with the ground or other components, thereby extending the service life of the core driller.

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0038] Reference Figures 1 to 3The utility model provides an embodiment: a device for loading and unloading a drilling and coring machine, comprising a carriage 1. The carriage 1 serves as the main bearing structure of the entire device and has a large internal space for accommodating the drilling and coring machine. A clamping mechanism for clamping and positioning is provided on the top of the carriage 1, and a tilting mechanism for facilitating loading and unloading is provided on the left side of the carriage 1. The tilting mechanism includes a fixed frame 13, the right side of the fixed frame 13 is fixedly connected to the left side of the carriage 1, the outer portion of the fixed frame 13 is rotatably connected to a rotating door 14, the outer portion of the rotating door 14 is slidably connected to the inner left side of the carriage 1, and the bottom of the rotating door 14 is fixedly connected to a triangular block 15. The sliding connection design of the rotating door 14 and the carriage 1 enables it to remain stable during rotation and fits tightly with the carriage 1 to prevent shaking or jamming. When the rotating door 14 is opened and in contact with the ground, the triangular block 15 can provide effective support for the rotating door 14, preventing it from sinking or deforming when bearing the weight of the drilling and coring machine, thereby ensuring the safety of the loading and unloading process. A buffer mechanism is provided on the right side of the interior of carriage 1 for cushioning. The clamping mechanism includes a drive assembly, the bottom of which is mounted on the top of carriage 1. The drive assembly includes a motor 2, which serves as the power source. The bottom of motor 2 is mounted on the top of carriage 1. The output end of motor 2 is fixedly connected to a drive shaft 3, the outer end of which is rotatably connected to the interior of carriage 1. The bottom of drive shaft 3 is fixedly connected to a rotating plate 4. Driven by motor 2, drive shaft 3 can rotate stably, driving rotating plate 4 in a circular motion.
[0039] Reference Figures 2 to 4The driving assembly is internally fixedly connected to two fixed rods 5, and the tops of the two fixed rods 5 are fixedly connected to the limiting plate 6. Two arc-shaped grooves 7 are provided inside the carriage 1. The outside of the fixed rods 5 is slidably connected to the inside of the arc-shaped grooves 7. During the movement of the entire clamping mechanism, the fixed rods 5 slide along the arc-shaped grooves 7, playing the role of guiding and stabilizing the structure. The outsides of the two fixed rods 5 are rotatably connected to the rotating rod 8. The top of the rotating rod 8 is rotatably connected to the bottom of the rotating plate 4, and when the rotating rod 8 moves, it can guide the fixed rod 5 to move along a specific arc trajectory, thereby realizing the opening and closing action of the clamping plate 11, ensuring effective clamping of the core drilling machine. The inner far side of the two rotating rods 8 is fixedly connected to a connecting shaft 9, and the outside of the two connecting shafts 9 is rotatably connected to a connecting rod 10. The connecting shaft 9 can rotate flexibly under the drive of the rotating rod 8 and provides a stable connection point for the connecting rod 10, so that the connecting rod 10 can move accordingly with the movement of the connecting shaft 9. The two connecting rods 10 are fixedly connected to the far side with a clamping plate 11, the outside of the clamping plate 11 is slidably connected to the inside of the carriage 1, and the inside of the carriage 1 is fixedly connected with a guide rod 12. The outside of the clamping plate 11 is slidably connected to the inside of the guide rod 12. Under the push or pull of the connecting rod 10, the clamping plate 11 moves linearly along the guide rod 12. The clamping or loosening operation of the core drilling machine is realized through the relative movement of the clamping plates 11 on both sides.
[0040] Reference Figures 3 to 5The buffer mechanism includes two fixed sleeves 16, which provide space restrictions for the movement of the spring 18 and the sliding ring 19. The left sides of the two fixed sleeves 16 are fixedly connected to the right side of the exterior of the carriage 1. The interiors of the two fixed sleeves 16 are fixedly connected to the sliding shafts 17. The exteriors of the two sliding shafts 17 are sleeved with springs 18. One end of the spring 18 is fixedly connected to the interior of the fixed sleeves 16, and the other end of the spring 18 is fixedly connected to the right side of the sliding ring 19. When the core drilling machine moves down along the rotating door 14, the spring 18 absorbs the downward force by compression. When the pressure is reduced, the spring 18 rebounds and releases the energy, thereby buffering the downward force of the core drilling machine passing through the rotating door 14 when it is unloaded, protecting the core drilling machine from bumps and damage. The interior of the carriage 1 is fixedly connected to two sliding rings 19. The exterior of the sliding shaft 17 is slidably connected to the interior of the sliding rings 19. A connecting rope 20 is fixedly connected to the left side of each sliding ring 19. During the buffering process, the sliding ring 19 slides on the sliding shaft 17, driving the connecting rope 20 to move. A connecting disk 21 is fixedly connected to the left side of each sliding shaft 17. Multiple guide rings 22 are fixedly connected to the exterior of each connecting disk 21. The guide rings 22 are used to guide the sliding of the connecting rope 20. The exterior of the connecting rope 20 is slidably connected to the interior of the guide ring 22. A hook 23 is fixedly connected to the left side of each connecting rope 20. When the coring machine is removed, the hook 23 is hooked to the exterior of the coring machine. A switch door 24 is rotatably connected to the interior right side of the carriage 1. Universal wheels 25 are fixedly connected to the four corners of the bottom of the carriage 1.
[0041] Working principle: When using the present loading and unloading device for the core drilling machine, the rotating door 14 can be opened first, and then the triangular block 15 will be in contact with the ground, thereby providing effective support for the rotating door 14, and then the core drilling machine can be pushed into the interior of the carriage 1 along the rotating door 14, and then the motor 2 can be started to drive the drive shaft 3 and the rotating plate 4 to rotate, and then the fixed rod 5 can be made to slide inside the arc groove 7, at which time the rotating rod 8 will be driven to rotate, and then the connecting rod 10 can be driven to move, and then the clamping plate 11 can be driven to slide outside the guide rod 12, so that the clamping plate 1 1 can effectively clamp and fix the core drilling machine, thereby realizing quick loading and unloading of the core drilling machine. When unloading the core drilling machine, the hook 23 can be hooked on the outside of the core drilling machine first, and then the core drilling machine can be pushed out from the inside of the carriage 1. When moving downward along the rotating door 14, the hook 23 will drive the guide ring 22 to move, and then drive the sliding ring 19 to slide on the outside of the sliding shaft 17, and then the spring 18 will be compressed and rebounded, so that the downward force of the core drilling machine through the rotating door 14 can be realized when unloading, thereby preventing the core drilling machine from being bumped and damaged during loading and unloading.
[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
