[0001] The invention relates to the technical field of water well drilling rigs, in particular to a clamp used for water well drilling rigs. Background Art

[0002] In the field of water resource development and utilization, water well drilling rigs, as core equipment for obtaining groundwater resources, are widely used in agricultural irrigation, domestic water supply, industrial production water extraction and other scenarios. From providing water sources for crop growth in vast farmlands, to delivering daily water for residents around cities, to ensuring production water needs in industrial plants, water well drilling rigs play an indispensable role. During the operation of water well drilling rigs, the clamp, as a key component, undertakes important tasks such as stabilizing the drill rod and controlling the drill rod in and out of the borehole.

[0017] During use of the present invention, after the drill rod is fixed, during the process of using the drill rod to drill a water well, the drill rod will be affected by the underground rocks and vibrate violently.

When the drill rod is in use, a large amount of soil and impurities will be attached to the outer wall of the fixing mechanism and the clamping mechanism inside the shell. When the added drill rod is fixed, the problem of unstable fixation will occur due to the influence of the soil and impurities. At this time, the soil and impurities inside the shell can be fully flushed under the action of the water pump, the water pipe, the delivery pipe and the nozzle, thereby improving the subsequent fixing effect of the drill rod, avoiding excessive manual intervention, and greatly reducing the labor intensity of the staff.

At the same time, with the cooperation of the mounting column 322, the return spring 325 and the limit rod 324, drill rods of different shapes and sizes can be further effectively fixed to avoid the drill rod from being stuck in the drill. The second buffer frame 34 is made of elastic rubber, so when vibration occurs, the second buffer frame 34 will partially absorb the vibration, so as to avoid the vibration generated by the drill pipe from being continuously transmitted to the transmission equipment and the drilling rig, thereby protecting them and greatly improving the use effect of the device.

[0025] Embodiment 3, according to Figure 1 , Figure 2 as well as Figure 3As shown, the buffer mechanism 1 includes a shell 11, a connecting plate 12 is fixedly installed on the top of the shell 11, four limit blocks 121 are fixedly installed on the outer wall of the connecting plate 12, a mounting box 125 is provided on the outer wall of the connecting plate 12, and the outer wall of the limit block 121 is movably embedded in the interior of the mounting box 125, a rubber pad 122 is fixedly installed on the inner wall of the mounting box 125, a buffer pad 123 is fixedly installed on one side of the outer wall of the rubber pad 122, an energy absorbing pad 124 is fixedly installed on one side of the outer wall of the buffer pad 123, a fixing groove 126 is provided on the top of the mounting box 125, a buffer spring 13 is fixedly installed on one side of the inner wall of the mounting box 125, and one side of the outer wall of the buffer spring 13 is fixedly connected to one side of the outer wall of the connecting plate 12, and the buffer A damper 131 is provided on the inner surface wall of the impact spring 13, a water pump 14 is fixedly installed on the top of the outer shell 11, and the outer surface wall of the water pump 14 is fixedly connected with a water pipe 141, and two support frames 15 are fixedly installed on the inner surface wall of the outer shell 11. A group of first insertion grooves 151 are opened on the outer surfaces of the two support frames 15, and a group of nozzles 152 are fixedly inserted on the inner surfaces of the two groups of first insertion grooves 151. The outer surfaces of each group of the two groups of nozzles 152 are fixedly connected with a delivery pipe 153, and the outer surface wall of the delivery pipe 153 is fixedly connected with the outer surface wall of the water pipe 141, one side of the inner wall of the outer shell 11 is fixedly connected to one side of the outer wall of the first buffer frame 212, and one side of the inner wall of the outer shell 11 is fixedly connected to one side of the outer wall of the second buffer frame 34.

[0026] In this embodiment, after the drill rod is fully installed and fixed, the installation box 125 is fully and effectively fixed to the power device of the drilling rig under the action of the fixing groove 126 and the external structure. Then, under the cooperation of the drilling rig and the power device, the drill rod is driven to rotate and move downward, so as to drill the water well. During the drilling process, the drill rod will vibrate due to the influence of the hard rock, and the vibration will continue to be transmitted. When the vibration generated by the drill rod is transmitted to the connecting plate 12, since the rubber pad 122 is made of elastic rubber, it can partially resist the transmitted vibration. The remaining vibration will continue to be transmitted. Since the buffer pad 123 is made of EPDM recycled rubber, the vibration can be further absorbed by the buffer pad 123. Then, under the action of the energy absorbing pad 124, since the energy absorbing pad 124 is made of polyurethane or EVA foam, the vibration generated by the drilling rod during operation can be fully absorbed. At the same time, the vibration can cause the connecting plate 12 to move inside the installation box 125. When the connecting plate 12 is vibrated and moves upward inside the installation box 125, the buffer spring 13 is When the buffer spring 13 is squeezed to a certain value, it will generate a large rebound force. At this time, the rebound force can be partially absorbed by the damper 131, thereby preventing a large vibration from continuously acting on the installation box 125, thereby preventing the vibration from continuously being transmitted to other mechanisms of the drilling rig, protecting the drilling rig, and preventing the internal parts of the drilling rig from being damaged during high-intensity use, thereby effectively extending its service life. When the drilling rig is drilling a water well and the drill rod is not long enough to connect a new drill rod, the clamping mechanism 2 and the fixing mechanism 3 The drill rod will be loosened, and under the operation of the staff, one end of the new drill rod will be connected to the drill rod inside the well, and the other end will be inserted into the shell 11. After a long period of drilling, a large amount of mud, sand and gravel will appear inside the shell 11. At this time, under the action of the water pump 14, the external water source is sucked out and sprayed from the nozzle 152 through the water pipe 141 and the delivery pipe 153, so as to flush the mud, sand and gravel inside the shell 11, and avoid the mud, sand and gravel to affect the subsequent drill rod, thereby greatly improving the practicability of the device and improving the fixing effect of the drill rod.

[0027] The working principle of the whole mechanism is as follows: when a drilling rig is needed to drill a water well, the drill rod is first placed in a suitable position under the operation of the staff, and then the clamping mechanism 2 is transported to a suitable position under the action of the drilling rig driving device, and then the gear row 251 is driven to move inside the mounting frame 21 under the action of the hydraulic telescopic rod 26 and the limit frame 25, and at the same time, the gear 23 is driven to rotate under the action of the meshing wheel 24, thereby driving the movable column 221 to move inside the movable groove 22, thereby driving the mounting plate 222 and the splitting vise 224 to move toward the middle, so as to squeeze and fix the drill rod. Under the action of the splitting vise 224, the drill rod can be fully fixed, and under the action of the anti-slip pad 225, The drill rod can be prevented from loosening and falling off, thereby improving the drilling effect of the drill rod. After the drill rod is initially fixed, the first transmission wheel 313 is driven to rotate under the action of the motor 312, and the bidirectional threaded rod 33 is driven to rotate under the action of the second transmission wheel 331, thereby driving the slider 32 to move toward the middle inside the slide groove 314, and the drill rod can be further squeezed and fixed under the action of the mounting column 322, the return spring 325 and the limit rod 324. At the same time, with the cooperation of the mounting column 322, the return spring 325 and the limit rod 324, drill rods of different shapes and sizes can be further effectively fixed, thereby preventing the drill rod from loosening and falling off during the drilling process, and greatly improving the drilling effect of the drill rod on the water well. The effect is improved, and the practicality of the fixing mechanism 3 is improved, so that it can be applied to more types of drill rods. When the drill rod is fully installed and fixed, the installation box 125 is fully and effectively fixed to the power device of the drilling rig under the action of the fixing groove 126 and the external structure. Then, under the cooperation of the drilling rig and the power device, the drill rod is driven to rotate and move downward, so as to drill the water well. During the drilling process, the drill rod will vibrate due to the influence of hard rock, and the vibration will continue to be transmitted. Under the action of the first buffer frame 212 and the second buffer frame 34, the vibration transmitted by the drill rod can be partially absorbed. When the vibration generated by the drill rod is transmitted to the connecting plate 12 when it is working, since the rubber pad 122 is made of elastic rubber, it can be The transmitted vibration is partially absorbed, and the remaining vibration will continue to be transmitted. Since the buffer pad 123 is made of EPDM recycled rubber, the vibration can be further absorbed under the action of the buffer pad 123. Then, under the action of the energy absorbing pad 124, since the energy absorbing pad 124 is made of polyurethane or EVA foam, the vibration generated by the drill rod during operation can be fully absorbed under the action of the energy absorbing pad 124. At the same time, the vibration will cause the connecting plate 12 to move inside the installation box 125. When the connecting plate 12 is vibrated and moves upward inside the installation box 125, the buffer spring 13 will be squeezed. When the buffer spring 13 is squeezed to a certain value, it will generate a large rebound force. At this time, under the action of the damper 131,The rebound force can be partially absorbed, so as to avoid large vibrations from continuously acting on the installation box 125, thereby preventing the vibrations from being continuously transmitted to other mechanisms of the drilling rig, thereby protecting the drilling rig, preventing the internal parts of the drilling rig from being damaged during high-intensity use, and effectively extending its service life. When the drilling rig is drilling a water well, if the drill rod is not long enough and a new drill rod needs to be connected, the clamping mechanism 2 and the fixing mechanism 3 will loosen the drill rod, and under the operation of the staff, one end of the new drill rod is connected to the drill rod inside the water well, and the other end is inserted into the shell 11. After a long period of drilling, a large amount of mud and gravel will appear inside the shell 11. At this time, the external water source is sucked out by the water pump 14, and sprayed out from the nozzle 152 through the water pipe 141 and the delivery pipe 153, thereby flushing the mud and gravel inside the shell 11, and preventing the mud and gravel from affecting the subsequent fixation of the drill rod, thereby improving the drilling effect of the drilling rig on the water well.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
