Description

Technical Field

[0001] This utility model relates to the field of geological exploration technology, specifically to a protective device for preventing stuck drill bits in geological engineering exploration drilling equipment. Background Technology

[0002] Geological engineering exploration drilling equipment is a core tool in the field of geological engineering used to obtain information on underground rock and soil layers, conduct resource exploration or engineering geological surveys. It penetrates the earth's surface through mechanical drilling to collect rock cores, soil samples or test underground physical parameters, providing basic data for engineering design, resource development or geological research.

[0003] Currently, in most existing geological engineering exploration drilling equipment, when the drill bit is overloaded or jammed by foreign objects, the motor continues to output power to the transmission system. The huge stress generated will directly act on various components of the motor and transmission system, which can easily lead to serious failures such as motor burnout, transmission gear breakage, and transmission shaft bending deformation. This will not only significantly shorten the service life of the equipment and increase maintenance costs, but also interrupt drilling operations due to sudden equipment failure, affecting the progress of the project. In view of this, we propose a drill jamming protection device for geological engineering exploration drilling equipment. Utility Model Content

[0004] The main purpose of this utility model is to provide a protective device against stuck drill bits for geological engineering exploration drilling equipment, which can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model proposes a protective device for preventing stuck drill bits in geological engineering exploration drilling equipment, comprising a vehicle body, a support frame and an electrical box on the vehicle body, a moving mechanism and a drilling mechanism on the support frame, and a protective mechanism on the drilling mechanism, the protective mechanism comprising:

[0006] The cover is penetrated by a screw and threadedly connected to the screw. The screw is penetrated by a sliding rod and slidably connected to the sliding rod. A spring is provided between the two. A ball bearing is provided at the bottom end of the sliding rod to reduce the friction between it and the second locking plate.

[0007] Card holder two, the outer wall of the card holder two is provided with multiple sets of circular protrusions;

[0008] Card holder one, wherein the card holder one has multiple sets of grooves.

[0009] Preferably, a clamping connector is connected to the outer wall of the clamping plate, and a drill bit is provided below the clamping connector. The two are assembled by bolts and nuts.

[0010] Preferably, the drilling mechanism includes a movable plate, the outer wall of which is equipped with a motor, the output end of which is connected to an elastic telescopic rod, and the elastic telescopic rod is assembled with a clamping plate two by bolts and nuts.

[0011] Preferably, the snap-fit ​​connector passes through the bearing and is fixedly connected to the inner wall of the bearing, and the outer wall of the bearing is connected to the inner wall of the movable plate.

[0012] Preferably, the top of the screw is provided with a hexagonal block, and the hexagonal block is equipped with a sliding sleeve, and the outer wall of the sliding sleeve is connected to a rod body to facilitate the rotation of the screw.

[0013] Preferably, the cover is equipped with a push-button alarm and has a push-button switch on its back.

[0014] Preferably, the outer wall of the sliding rod is provided with an inclined block.

[0015] This utility model provides a protective device for preventing stuck drill bits in geological exploration drilling equipment. It has the following beneficial effects:

[0016] (1) The anti-jamming protection device of the geological engineering exploration drilling equipment has the following characteristics: During the drilling process, when the drill bit stops rotating due to overload or foreign object jamming, the motor output shaft continues to drive the second clamping disc to rotate through the elastic telescopic rod. At this time, the protrusion of the second clamping disc generates a circumferential force on the groove of the first clamping disc. Since the first clamping disc is locked, this force is decomposed into an axial component, which forces the second clamping disc to overcome the spring preload and move upward, causing the protrusion to disengage from the groove. The second clamping disc then begins to rotate freely. This design effectively cuts off the power transmission path, avoids damage to the motor and transmission system due to overload, and greatly improves the service life and reliability of the equipment.

[0017] (2) The anti-jamming protection device of the geological engineering exploration drilling equipment, when the jamming occurs, the second jamming plate moves up and drives the sliding rod to move up synchronously, so that the inclined block triggers the press switch, and then the press-type alarm is activated to emit an audible and visual alarm. This mechanism allows the operator to quickly detect the abnormality of the equipment, stop the machine in time to troubleshoot the fault, and avoid more serious equipment damage or safety accidents caused by the continuous expansion of the jamming problem.

[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] Please see Figures 1-6 This utility model proposes a protective device for preventing stuck drill in geological engineering exploration drilling equipment, including a vehicle body 1, a support frame 2 and an electrical box 3 on the vehicle body 1, a moving mechanism 4 and a drilling mechanism on the support frame 2, and a protective mechanism on the drilling mechanism.

[0030] In the embodiments of this utility model, in order to protect the device, the protective mechanism specifically includes a cover 55, which is penetrated by a screw 551 and threadedly connected to the screw 551. The top of the screw 551 is provided with a hexagonal block 552, and the hexagonal block 552 is matched with a sliding sleeve 553. The outer wall of the sliding sleeve 553 is connected to a rod 554 to facilitate the rotation of the screw 551. The screw 551 is penetrated by a sliding rod 555 and slidably connected to the sliding rod 555. A spring 556 is provided between the two. The bottom end of the sliding rod 555 is provided with a ball 557. The outer wall of the second snap-fit ​​plate 57 is provided with multiple sets of circular protrusions 571. The first snap-fit ​​plate 56 is provided with multiple sets of grooves 561.

[0031] Furthermore, the drilling mechanism includes a movable plate 51, a motor is provided on the outer wall of the movable plate 51, and an elastic telescopic rod 58 is connected to the output end of the motor. The elastic telescopic rod 58 is assembled with the clamping plate 57 by bolts and nuts. The clamping joint 53 passes through the bearing 54 and is fixedly connected to the inner wall of the bearing 54. The outer wall of the bearing 54 is connected to the inner wall of the movable plate 51.

[0032] Furthermore, a clamping connector 53 is connected to the outer wall of the clamping plate 56, and a drill bit 52 is provided below the clamping connector 53. The two are assembled by bolts and nuts.

[0033] Furthermore, the cover 55 is fitted with a push-button alarm 59, and a push-button switch 591 is provided on its back, and an inclined block 558 is provided on the outer wall of the sliding rod 555.

[0034] In this invention, during use, the screw 551 is first tightened via the sliding sleeve 553. The screw 551, driven by the threaded transmission, causes the sliding rod 555 to move downwards. When the sliding rod 555 reaches a specific position, the ball bearing 557 at its bottom contacts the outer wall of the retaining plate 57. If the screw 551 is continued to be tightened, the sliding rod 555 cannot move further downwards due to the restriction imposed by the retaining plate 57. The pressure continuously applied by the screw 551 begins to compress the spring 556. As the compression of the spring 556 increases, the positive pressure of the sliding rod 555 on the retaining plate 57 gradually increases. Subsequently, the motor is started, and the elastic telescopic rod 58 at the motor output end drives the retaining plate 57 to rotate synchronously. When the second clamping plate 57 rotates until the protrusion 571 coincides with the groove 561 of the first clamping plate 56, under the combined force of the sliding rod 555 and the screw 551, the second clamping plate 57 and the first clamping plate 56 achieve mechanical engagement, thereby driving the first clamping plate 56 to rotate synchronously, and finally driving the drill bit 52 to rotate, and then starting the moving mechanism 4 to perform drilling operations.

[0035] When drill bit 52 stops rotating due to overload or obstruction by foreign objects, clamping head 53 and clamping disc 56, which are fixedly connected to it, stop rotating simultaneously. At this time, the motor output shaft continues to drive clamping disc 57 to rotate through elastic telescopic rod 58. The protrusion 571 of clamping disc 57 exerts a circumferential force on the groove 561 of clamping disc 56. Since clamping disc 56 is locked, this force is decomposed into an axial component at the inclined contact point between protrusion 571 and groove 561, forcing clamping disc 57 to overcome the preload of spring 556 and move upward. As clamping disc 57 moves upward, protrusion 571 disengages from groove 561, and clamping disc 57 begins to idle, effectively cutting off the power transmission path and preventing damage to the motor and transmission system due to overload, thus realizing the self-protection function of the device. When the fault is cleared, the elastic force pushes clamping disc 57 to reset, protrusion 571 re-embeds into groove 561, and normal transmission is restored.

[0036] When the second clamping plate 57 moves upward, its outer wall applies an upward thrust to the ball bearing 557, causing the sliding rod 555 to move upward synchronously. During this process, the inclined block 558 fixed to the outer wall of the sliding rod 555 moves upward as well, gradually contacting the push switch 591 and applying pressure. As the pressure increases, the push switch 591 is triggered, causing the internal circuit of the push-button alarm 59 to switch from an open circuit to a closed circuit. The alarm then emits an audible and visual alarm, promptly alerting the operator that the equipment has a stuck drill fault, allowing for quick shutdown and troubleshooting to prevent the fault from escalating.

[0037] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
