Description

Technical Field

[0001] This utility model relates to the technical field of hydraulic oil tanks, and in particular to a dual-channel oil tank. Background Technology

[0002] Core drilling rigs commonly suffer from hydraulic oil overheating issues, ranging from minor to severe. Excessive oil temperature in the tank can cause the following malfunctions: 1. Slower equipment operation, reduced work efficiency, and increased oil consumption; 2. Hydraulic oil viscosity decreases with rising temperature, resulting in poor lubrication performance, accelerated wear of hydraulic components, and damage to critical components such as hydraulic pumps, valves, and locks; 3. High temperatures increase internal leakage in the hydraulic system, causing instability in various performance aspects. The valve core and body of control valves expand due to heat, affecting valve core movement, accelerating wear, and even causing jamming, thus impacting hydraulic system operation; 4. Accelerated oxidation of the hydraulic oil, leading to oil deterioration and reduced service life; 5. High temperatures accelerate the aging of seals, reducing sealing performance and eventually causing external leaks, widespread oil seepage, and difficulty in cleaning.

[0003] Therefore, it is necessary to invent a dual-channel oil tank. This utility model changes the traditional single-channel oil tank to a dual-channel mode. By adopting this dual-channel mode, the problem of excessively high hydraulic oil temperature in the oil tank is greatly solved, avoiding various drawbacks caused by excessively high hydraulic oil temperature, improving the working efficiency of the drilling rig, and also improving economic benefits. This utility model utilizes a slight shaking of the oil tank to increase the contact area between the hydraulic oil and the air, thereby rapidly reducing the oil temperature. Utility Model Content

[0019] The advantages of this utility model compared with the prior art are:

[0020] 1. This utility model changes the traditional single-channel oil tank to a dual-channel mode. By adopting this dual-channel mode, the problem of excessively high hydraulic oil temperature in the oil tank is greatly solved, avoiding various drawbacks caused by excessively high hydraulic oil temperature, improving the working efficiency of the drilling rig and also improving economic benefits. This utility model utilizes a small amount of shaking of the oil tank to increase the contact area between the hydraulic oil and the air, thereby rapidly reducing the oil temperature.

[0021] 2. The hydraulic oil in the system pipeline returns from the return oil filter element to the left oil tank, passes through the filter plate and U-shaped groove in the left oil tank, and then enters the right oil tank through the connecting oil pipe. After passing through the filter plate in the right oil tank, it flows out from the small suction oil filter element and the large suction oil filter element in the right oil tank and enters the system, completing the hydraulic oil's journey in the oil tank and also completing the hydraulic oil cooling process. The left and right oil tanks form a dual channel to achieve the purpose of hydraulic oil cooling and filtration.

[0022] 3. This utility model uses a motor to drive a swing rod to swing, which in turn moves the connecting support rod, thereby pulling the small slider I in another lifting mechanism to move. Since the spring inside this lifting mechanism provides a pulling force to the small slider II, the small slider I drives the small slider II to move outward, which in turn drives the connecting rod I and the connecting rod II to swing, thereby driving the small slider III and the small slider IV to move, thus raising the rectangular block and causing the right oil tank to drop slightly. This causes the right oil tank and the left oil tank to tilt, causing the hydraulic oil inside the right oil tank and the left oil tank to slosh, thereby increasing the contact area between the hydraulic oil and the air, and allowing the oil temperature to drop rapidly.

[0033] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model patent. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0034] In the description of this utility model, it should be noted that the terms "upper," "lower," "front," "rear," "left," and "right," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use. They are merely simplified descriptions for ease of description and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model patent. Furthermore, for ease of description, spatial relative terms such as "below," "below," "under," "above," and "above" may be used to describe the relationship of one element or feature relative to other elements or features as shown in the figures. Spatial relative terms are intended to encompass different orientations of the device in use or operation other than those shown in the accompanying drawings. The device may have other orientations (rotated 90 degrees or in other orientations), and the spatial relative descriptive terms used herein can be interpreted accordingly.

[0035] Implementation, for example Figures 1-9 As shown, a dual-channel fuel tank includes: a fuel tank section 1 and a bottom swaying section 2;

[0036] The oil tank section 1 is fixedly installed on the bottom rocking section 2, which is attached to the predetermined installation area by a fastening mechanism. A controller is fixedly installed on the oil tank section 1. The controller receives signals through a signal processor and controls the electrical components of the equipment to operate in an orderly manner through a central processing unit. Specifically, traditional oil tanks are single-channel, and excessive oil temperature in a single-channel oil tank can cause a series of problems and malfunctions. The bottom rocking section 2 is used to improve the oil tank to a dual-channel mode, thereby lowering the oil temperature and solving the problem caused by excessive oil temperature. At the same time, the bottom rocking section 2 shakes the oil tank section 1, which can cause the hydraulic oil inside the oil tank section 1 to slosh, increasing the contact area with air and thus lowering the oil temperature as quickly as possible.

[0037] In one optional embodiment of this utility model, such as Figures 3-5 As shown, the oil tank section 1 includes: a right oil tank 101, a small oil suction filter element 102, a large oil suction filter element 103, and a U-shaped groove 106;

[0038] The right oil tank 101 has a U-shaped groove 106 inside. The right oil tank 101 has two square grooves of different sizes. A filter plate is fixedly installed inside each square groove. A small oil suction filter element 102 and a large oil suction filter element 103 are installed inside the two square grooves. The small oil suction filter element 102 and the large oil suction filter element 103 are connected to one end of the U-shaped groove 106.

[0039] In one optional embodiment of this utility model, such as Figures 3-4As shown, the oil tank section 1 also includes: a left oil tank 104 and a return oil filter element 105;

[0040] The left oil tank 104 has a circular groove, in which a filter plate is fixedly installed. A return oil filter element 105 is installed in the circular groove of the left oil tank 104. The left oil tank 104 is connected to the right oil tank 101 through a connector. The interior of the left oil tank 104 has a U-shaped groove 106, the other end of which is connected to the return oil filter element 105. Specifically, the hydraulic oil in the system pipeline returns to the interior of the left oil tank 104 from the return oil filter element 105, passes through the filter plate and U-shaped groove 106 in the left oil tank 104, and then enters the right oil tank 101 through the connecting oil pipe. After passing through the filter plate in the right oil tank 101, it flows out from the small suction oil filter element 102 and the large suction oil filter element 103 in the right oil tank 101 and enters the system, completing the hydraulic oil's journey in the oil tank and also completing the hydraulic oil cooling process. The left oil tank 104 and the right oil tank 101 form a dual channel to achieve the purpose of hydraulic oil cooling and filtration.

[0041] In one optional embodiment of this utility model, such as Figures 6-9 As shown, the bottom swaying part 2 includes: a rectangular base plate 201, a U-shaped bracket 202, a motor 203, a swing rod 204, a connecting support rod 205, a spring 218, and a lifting mechanism;

[0042] A rectangular base plate 201 is attached to a predetermined installation area via a fastening mechanism. Two lifting mechanisms are fixedly installed on the rectangular base plate 201, and the two lifting mechanisms are symmetrically distributed. There are two U-shaped brackets 202, which are also symmetrically distributed and fixedly installed on the rectangular base plate 201. A motor 203 is fixedly installed on one of the U-shaped brackets 202. The shaft of the motor 203 is fixedly connected to a swing rod 204, which is rotatably mounted on the two U-shaped brackets 202. The swing rod 204 has a groove that mates with a round rod on a connecting support rod 205. A round rod is fixedly installed in the middle of the connecting support rod 205. The connecting support rod 205 is slidably mounted on the two U-shaped brackets 202. One end of the connecting support rod 205 is fixedly connected to a small slider II 210 of the lifting mechanism, and the other end of the connecting support rod 205 is fixedly connected to a small slider I 208 of the lifting mechanism. A spring is also present. There are two springs 218. One end of spring 218 is fixedly connected to a small slider I 208 of a lifting mechanism, and the other end of spring 218 is fixedly connected to the rectangular plate 207 of the lifting mechanism. The other spring 218 is fixedly connected to one end of a small slider II 210 of another lifting mechanism, and the other end of spring 218 is fixedly connected to the rectangular plate 207 of another lifting mechanism. Specifically, during the process of hydraulic oil flowing from the left oil tank 104 into the right oil tank 101, the motor 203 drives the swing rod 204 to swing, which in turn drives the connecting support rod 205 to move, thereby raising one lifting mechanism and lowering the other lifting mechanism, so that the right oil tank 101 and the left oil tank 104 swing, thereby causing the hydraulic oil inside the right oil tank 101 and the left oil tank 104 to slosh, thereby increasing the contact area between the hydraulic oil and the air, thus helping to quickly reduce the oil temperature.

[0043] In one optional embodiment of this utility model, such as Figures 6-9 As shown, the lifting mechanism includes: a small base plate 206, a rectangular plate 207, a small slider I 208, a connecting rod I 209, a small slider II 210, and a connecting rod II 211;

[0044] Small base plate 206 is fixedly installed on rectangular base plate 201. Two rectangular plates 207 are fixedly installed on small base plate 206. Each rectangular plate 207 has two sliding grooves. There are two small sliders I 208, which are slidably installed on the two rectangular plates 207 respectively. Each small slider I 208 is rotatably connected to one end of a connecting rod I 209. There are two connecting rods I 209, which are symmetrically distributed. The other end of each connecting rod I 209 is rotatably connected to one of the small sliders III 212. The middle part of each connecting rod I 209 is rotatably connected to the intermediate shaft of a connecting rod II 211. There are two small sliders II 210, which are slidably installed in the other groove of a rectangular plate 207. Each small slider II 210 is rotatably connected to one end of a connecting rod II 211. There are two connecting rods II 211, and the other end of each connecting rod II 211 is rotatably connected to a small slider IV 214.

[0045] In one optional embodiment of this utility model, such as Figures 3-9 As shown, the lifting mechanism also includes: small slider III 212, rectangular block 213 and small slider IV 214;

[0046] There are two rectangular blocks 213, each with two grooves; there are two small sliders III 212, which are symmetrically distributed, each slidingly mounted in one groove of a rectangular block 213, and each rotatably connected to one end of a connecting rod I 209; there are two small sliders IV 214, which are slidably mounted in one groove of a rectangular block 213.

[0047] In one optional embodiment of this utility model, such as Figure 3 , Figure 9 As shown, the lifting mechanism also includes: foot seat I 215, foot seat II 216 and square plate 217;

[0048] There are two feet I 215, which are fixedly installed on the rectangular block 213. Each foot I 215 is rotatably connected to a foot II 216. There are two feet II 216, which are slidably installed in the grooves of the square plate 217. There are two square plates 217, which are fixedly installed on the right oil tank 101 and the left oil tank 104, respectively. Specifically, the motor 203 drives the swing rod 204 to swing, which in turn drives the connecting rod 205 to move, thereby pushing the small slider II 210 in a lifting mechanism to move. Since the spring 218 inside this lifting mechanism provides a thrust to the small slider I 208, the small slider II 210 drives the small slider I 208 to move outward, which in turn drives the connecting rod I 209 and the connecting rod II 211 to swing, thereby driving the small slider III 212 and the small slider IV 214 to move, thereby lifting the rectangular block 213 and thus lifting the left oil tank 104 slightly.

[0049] In order to ensure that the right oil tank 101 can descend smoothly during the lifting of the left oil tank 104, during the lifting of the rectangular block 213, the feet I 215 and II 216 rotate, and the feet II 216 slide in the square plate 217.

[0050] Simultaneously, the motor 203 drives the swing rod 204 to swing, which in turn drives the connecting support rod 205 to move, thereby pulling the small slider I 208 in another lifting mechanism to move. Since the spring 218 inside this lifting mechanism provides a pulling force to the small slider II 210, the small slider I 208 drives the small slider II 210 to move outward, which in turn drives the connecting rod I 209 and the connecting rod II 211 to swing, thereby driving the small slider III 212 and the small slider IV 214 to move, thereby raising the rectangular block 213, which causes the right oil tank 101 to drop slightly. This causes the right oil tank 101 and the left oil tank 104 to tilt, which causes the hydraulic oil inside the right oil tank 101 and the left oil tank 104 to slosh.

[0051] Working principle:

[0052] This invention changes the traditional single-channel oil tank design to a dual-channel design. By adopting this dual-channel design, the problem of excessively high hydraulic oil temperature in the oil tank is greatly solved, avoiding various drawbacks caused by excessively high hydraulic oil temperature, improving the working efficiency of the drilling rig, and also improving economic benefits. This invention utilizes a slight shaking of the oil tank to increase the contact area between the hydraulic oil and air, thereby rapidly reducing the oil temperature.

[0053] The hydraulic oil in the system pipeline returns from the return oil filter element 105 to the inside of the left oil tank 104, passes through the filter plate and U-shaped groove 106 in the left oil tank 104, and then enters the right oil tank 101 through the connecting oil pipe. After passing through the filter plate in the right oil tank 101, it flows out from the small suction oil filter element 102 and the large suction oil filter element 103 in the right oil tank 101 and enters the system, completing the hydraulic oil's journey in the oil tank and also completing the hydraulic oil cooling process. The left oil tank 104 and the right oil tank 101 form a dual channel to achieve the purpose of hydraulic oil cooling and filtration.

[0054] The motor 203 drives the swing rod 204 to swing, which in turn drives the connecting rod 205 to move, thereby pushing the small slider II 210 in a lifting mechanism to move. Since the spring 218 inside this lifting mechanism provides a thrust to the small slider I 208, the small slider I 208 is driven to move outward through the small slider II 210, which in turn drives the connecting rod I 209 and the connecting rod II 211 to swing, thereby driving the small slider III 212 and the small slider IV 214 to move, thereby lifting the rectangular block 213, thus lifting the left oil tank 104 slightly.

[0055] In order to ensure that the right oil tank 101 can descend smoothly during the lifting of the left oil tank 104, during the lifting of the rectangular block 213, the feet I 215 and II 216 rotate, and the feet II 216 slide in the square plate 217.

[0056] Simultaneously, the motor 203 drives the swing rod 204 to swing, which in turn drives the connecting support rod 205 to move, thereby pulling the small slider I 208 in another lifting mechanism to move. Since the spring 218 inside this lifting mechanism provides a pulling force to the small slider II 210, the small slider I 208 drives the small slider II 210 to move outward, which in turn drives the connecting rod I 209 and the connecting rod II 211 to swing, thereby driving the small slider III 212 and the small slider IV 214 to move, thereby raising the rectangular block 213, which causes the right oil tank 101 to drop slightly. This causes the right oil tank 101 and the left oil tank 104 to tilt, which causes the hydraulic oil inside the right oil tank 101 and the left oil tank 104 to slosh.

[0057] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
