Technical Field
[0001] This utility model relates to the field of water well drilling rig technology, and in particular to a hydraulic water well drilling rig. Background Technology
[0002] Hydraulic water well drilling rigs are typically equipped with wheels or tracks for easy movement, and are usually fitted with outriggers. However, due to the varying types of soil at the drilling site, if the soil is damp and the ground is soft, the stability of the rig after it comes to rest decreases. Furthermore, mud often adheres to the surface of the drill rod after use, increasing the labor intensity of drill rod retrieval. A patent application published on the Chinese Patent Network, titled "A Fully Hydraulic Water Well Drilling Rig" (application number "201420110953.9"), describes a water well drilling rig that uses a hydraulic pump to control a hydraulic cylinder to automatically raise and lower the drilling tower, eliminating the need for hoisting equipment during relocation and thus improving the ease of retrieval. However, this rig is less effective on different types of ground, affecting the user's comfort. Summary of the Invention
[0003] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a hydraulic water well drilling rig that improves the convenience of stabilizing the water well drilling rig, increases the stability of the water well drilling rig when stationary on different types of ground, improves the convenience of handling mud on the drill rod surface, and improves the convenience of drill rod recovery.
[0004] This utility model also provides a hydraulic water well drilling rig as described above, comprising: a load-bearing frame, a hydraulic oil pump and a drill rod frame fixedly connected to the upper surface of the load-bearing frame, the hydraulic oil pump and the drill rod frame being distributed opposite each other on the left and right sides, a power head being provided on the surface of the drill rod frame, a positioning plate being fixedly connected to the right surface of the load-bearing frame, the power head and the positioning plate being distributed opposite each other vertically, a plurality of legs being fixedly connected to the surface of the load-bearing frame, a soil-breaking rod being provided at the lower end of the legs, the upper end of the soil-breaking rod penetrating into the interior of the legs and being threadedly connected to the legs, a sealing ring being fixedly connected to the lower end of the through hole on the surface of the positioning plate, the diameter of the sealing ring being larger than the diameter of the drill rod, an installation groove being provided on the upper surface of the positioning plate, the installation groove communicating with the through hole on the surface of the positioning plate, a reinforcing component being provided inside the installation groove, and the end of the reinforcing component away from the inner wall of the installation groove contacting the side surface of the drill rod.
[0005] According to the present invention, a hydraulic water well drilling rig has a receiving groove on the lower surface of the support leg, and the lower end of the soil-breaking rod is located inside the receiving groove. This improves the flatness of the support leg.
[0006] According to the present invention, a hydraulic water well drilling rig has a protective cover at the lower end of the soil-breaking rod, with the tip of the soil-breaking rod located at the protective cover. The protective cover is threadedly connected to a receiving groove to prevent soil from entering the receiving groove.
[0007] According to the present invention, in a hydraulic water well drilling rig, the depth of the receiving groove is the same as the height of the protective cover. When the drilling rig is not in use, the lower surface of the protective cover and the lower surface of the support leg are on the same plane. This reduces the impact of the protective cover on the balance of the support leg.
[0008] According to the present invention, a hydraulic water well drilling rig includes a sealing ring composed of an arc plate and a spring, wherein the arc surface of the arc plate contacts the surface of the drill rod. This improves the convenience of using the reinforcement components.
[0009] According to the present invention, in a hydraulic water well drilling rig, the two ends of the spring are fixedly connected to the inner wall of the arc plate and the mounting groove, respectively, and the lower surface of the arc plate does not contact the upper surface of the sealing ring. This improves the convenience of maintenance and reinforcement of the components.
[0010] According to the present invention, a hydraulic water well drilling rig has a conical cross-section at the lower end of the arc plate. After the two arc plates are joined together to form a circle, the diameter of the conical cross-section on the surface of the two arc plates is larger than the diameter of the drill rod joint. This improves the ease of lifting the drill rod.
[0011] According to the present invention, a hydraulic water well drilling rig has a water-permeable hole on the surface of the sealing ring, and the water-permeable hole has a conical structure. This prevents excessive water accumulation inside the installation groove. Beneficial effects

[0021] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0022] Reference Figure 1-5 This utility model discloses a hydraulic water well drilling rig, comprising: a load-bearing frame 1; a hydraulic oil pump 2 and a drill rod frame 3 fixedly connected to the upper surface of the load-bearing frame 1, with the hydraulic oil pump 2 and drill rod frame 3 distributed horizontally opposite each other; a power head 4 disposed on the surface of the drill rod frame 3; a positioning plate 5 fixedly connected to the right surface of the load-bearing frame 1, with the power head 4 and positioning plate 5 distributed vertically opposite each other; the above components cooperate to form the basic structure of a common hydraulic water well drilling rig; multiple support legs 8 fixedly connected to the surface of the load-bearing frame 1 for balancing the load-bearing frame 1; a soil-breaking rod 11 disposed at the lower end of the support leg 8, with the upper end of the soil-breaking rod 11 penetrating into the interior of the support leg 8 and connecting with the support leg. The 8-threaded connection and the soil-breaking rod 11 are used to increase the stability of the support leg 8 after it comes into contact with the ground. The lower surface of the support leg 8 is provided with a storage groove 13. The lower end of the soil-breaking rod 11 is located inside the storage groove 13. The lower end of the soil-breaking rod 11 is provided with a protective cover 12. The tip of the soil-breaking rod 11 is located at the protective cover 12. The protective cover 12 is threadedly connected to the storage groove 13. The depth of the storage groove 13 is the same as the height of the protective cover 12. When the drilling rig is not in use, the lower surface of the protective cover 12 is on the same plane as the lower surface of the support leg 8. The storage groove 13 and the protective cover 12 cooperate with each other to improve the convenience of storing the soil-breaking rod 11 and reduce the contact area between the soil-breaking rod 11 and the outside.
[0023] Specifically, the drill rod frame 3 is used to change the height of the power head 4, and the drill rod is directly connected to the power head 4. The drill rod is affected by the drill rod frame 3 and the power head 4 to carry out the soil breaking and drilling work. During the process of changing the length of the support leg 8 to balance the load-bearing frame 1, if the soil breaking rod 11 is taken out between the lowering support legs 8, the soil breaking rod 11 will be directly pierced into the ground due to the influence of gravity. After piercing the ground, the soil breaking rod 11 directly restricts the range of motion of the support leg 8. When the soil breaking rod 11 is rotated and pushed into the support leg 8, the tip of the soil breaking rod 11 is first isolated by the protective cover 12. After the protective cover 12 is completely inserted into the storage groove 13, the storage of the soil breaking rod 11 can be completed.
[0024] A sealing ring 14 is fixedly connected to the lower end of the through hole on the surface of the positioning plate 5. The diameter of the sealing ring 14 is larger than the diameter of the drill rod. A mounting groove 6 is provided on the upper surface of the positioning plate 5. The mounting groove 6 communicates with the through hole on the surface of the positioning plate 5. A reinforcing component 7 is provided inside the mounting groove 6. The end of the reinforcing component 7 away from the inner wall of the mounting groove 6 contacts the side surface of the drill rod. The reinforcing component 7 consists of an arc plate 9 and a spring 10. The arc surface of the arc plate 9 contacts the surface of the drill rod. The two ends of the spring 10 are fixedly connected to the arc plate 9 and the inner wall of the mounting groove 6, respectively. The lower surface of the arc plate 9 does not contact the upper surface of the sealing ring 14. The above components cooperate to form a cleaning mechanism to scrape off the mud and dirt on the drill rod surface. The lower end of the arc plate 9 is provided with a conical cut surface 16. After the two arc plates 9 are joined together to form a circle, the diameter of the conical cut surface 16 on the surface of the two arc plates 9 is larger than the diameter of the drill rod joint. The conical cut surface 16 is used to improve the smoothness of lifting the drill rod. The surface of the sealing ring 14 is provided with a water seepage hole 15. The water seepage hole 15 is a conical structure. The water seepage hole 15 is used to prevent excessive water accumulation inside the installation groove 6.
[0025] Specifically, during the process of lifting and retrieving the drill rod, larger mud clumps on the drill rod surface are directly scraped off by the sealing ring 14, while smaller mud clumps pass through the sealing ring 14 and directly contact the arc plate 9, which is in close contact with the drill rod surface and is scraped off. The deformation characteristics of the spring 10 provide the arc plate 9 with tilting conditions during the lifting and lowering of the drill rod, preventing the reinforcing component 7 from affecting the smoothness of the drill rod's lifting and lowering. The mud scraped off by the arc plate 9 falls through the gap between the drill rod and the sealing ring 14, while the sprayed water is discharged through the seepage hole 15, thereby preventing excessive accumulation of mud and water inside the installation groove 6.
[0026] Working principle: When the ground at the working area of the water well drilling rig is found to be too soft, the protective cover 12 restricts the soil breaking rod 11, and then the soil breaking rod 11 is taken out. During the descent of the support leg 8, the soil breaking rod 11 is directly inserted into the soil due to gravity. At this time, the water well drilling rig, which is now stationary, is balanced by the support leg 8. The soil breaking rod 11 inserted into the ground improves the stability after the support leg 8 is in action. Then, the drill rod is connected to the power head 4 to start drilling. After the drilling is completed, the drill rod is lifted up, and the larger mud clods on the surface of the drill rod are directly scraped off by the sealing ring 14. The mud flakes that are close to the surface of the drill rod are scraped off by the arc plate 9 after contacting it, thus eliminating the need for additional cleaning of the mud on the surface of the scraper.
[0027] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
