Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary tools, in particular to a Magnitogorsk funnel auxiliary device. Background Art

[0002] The Marsh funnel viscometer is an instrument for measuring the viscosity of drilling fluids as specified by the API standard. Its measuring principle is to use the time required for a certain amount of drilling fluid to flow freely from a fixed funnel under the action of gravity to represent the viscosity of the drilling fluid. At present, the use of the Marsh funnel is usually to first block the outlet of the funnel with your hand and keep the funnel upright, then pour the drilling fluid sample into the funnel, then quickly remove your fingers and use a stopwatch to time it at the same time. When the drilling fluid sample in the funnel flows through the mud cup, the timing ends and the time taken is recorded. Since the chemical additives in the drilling fluid sample are corrosive to a certain extent, when the staff blocks the outlet of the funnel with their hands, the drilling fluid sample will adhere to the staff's hands, and then when the staff tests the drilling fluid sample, there is a defect that the drilling fluid sample corrodes the staff's hands. Therefore, auxiliary devices are needed to measure the viscosity of the drilling fluid.

[0003] Prior art CN214439221U discloses an auxiliary device for a Magheraf funnel, comprising a support frame, in which the Magheraf funnel is arranged, and a sealing assembly is arranged on the support frame, and the sealing assembly is used to seal the funnel outlet. The auxiliary device is provided with a support frame and a sealing assembly, and the Magheraf funnel is placed in the support frame, so that the support frame supports the Magheraf funnel, and then the sealing assembly seals the funnel outlet.

[0004] However, the above-mentioned auxiliary device has the following disadvantages: in the process of measuring high-density and high-viscosity drilling fluid, the drilling fluid will stay in the Marsh funnel for a relatively long time, and the above-mentioned auxiliary device will appear to be "top-heavy". When subjected to external force, the device is prone to tilting and tipping over. In severe cases, the drilling fluid will flow out, which may lead to the failure of drilling fluid viscosity measurement, etc., and the stability is poor. At the same time, the above-mentioned equipment cannot be disassembled and occupies a large storage space.

[0005] Therefore, there is an urgent need to provide a Magnitogorsk auxiliary device, which can improve overall stability and reduce storage space compared to the prior art. Utility Model Content

[0034] like Figure 2 As shown, this embodiment provides a Magnitogorsk funnel auxiliary device, including a supporting bracket, three first connecting rods 4, a connecting member 5, three second connecting rods 6 and a placement platform 7. The supporting bracket is fixedly connected to the first connecting rod 4, and the three first connecting rods 4 are arranged at intervals along the circumference of the supporting bracket. The lower end of the first connecting rod 4 is detachably connected to the upper wall of the connecting member 5, the upper ends of the second connecting rods 6 are detachably connected to the connecting member 5, and the lower ends of the second connecting rods 6 are detachably connected to the placement platform 7.

[0035] The support frame includes a supporting upper ring 1 and a supporting lower ring 2. The supporting upper ring 1 is located above the supporting lower ring 2. The supporting upper ring 1 and the supporting lower ring 2 are arranged in parallel. The supporting upper ring 1 and the supporting lower ring 2 are fixedly connected to the first connecting rod 4. The angle between the axis of the first connecting rod 4 and the diameter of the supporting upper ring 1 is 60°; the supporting upper ring 1 and the supporting lower ring 2 are both provided with a receiving opening 3, and the receiving opening 3 set in the supporting upper ring 1 corresponds to the receiving opening 3 set in the supporting lower ring 2.

[0036] like Figure 3 As shown, the first connecting rod 4 includes a first telescopic assembly and a first connecting end, the first telescopic assembly includes a first telescopic rod 41 and a second telescopic rod 42, the second telescopic rod 42 is extended into the first telescopic rod 41, the length of the second telescopic rod 42 is equal to the length of the first telescopic rod 41, and the second telescopic rod 42 is connected to a plurality of locking blocks 421 at the end of the side wall of the first telescopic rod 41, preferably two of them, the first telescopic rod 41 is a hollow structure with an opening at the lower end, and a plurality of slide grooves 411 are arranged at intervals along the circumference of the first telescopic rod 41, and the slide grooves 411 are extended along the axis of the first telescopic rod 41, and the number of the slide grooves 411 is equal to the number of the locking blocks 421. The number is the same, two are provided, and two locking grooves 412 are further provided inside the first telescopic rod 41, and the locking grooves 412 are respectively located at the upper and lower ends of the slide groove 411, the locking groove 412 is cylindrical, and the slide groove 411 is elongated, and the locking groove 412 is connected to the slide groove 411, and the diameter of the opening at the lower end of the first telescopic rod 41 is the same as the outer diameter of the part of the second telescopic rod 42 where the locking block 421 is not provided; the first connecting end is integrally connected to the end of the second telescopic rod 42 away from the first telescopic rod 41, and the first connecting end is truncated cone-shaped, and the outer diameter of the first connecting end is gradually reduced from the end close to the second telescopic rod 42 to the end away from the second telescopic rod 42.

[0037] When the first connecting rod 4 is extended, the second telescopic rod 42 is stretched in a direction away from the top of the first telescopic rod 41. During the sliding process, the locking block 421 slides inside the slide groove 411. When the locking block 421 slides to the inside of the locking groove 412 connected to the lower end of the slide groove 411, the second telescopic rod 42 is rotated to make the locking block 421 slide to a position in the locking groove 412 that is not connected to the slide groove 411, thereby locking the position of the second telescopic rod 42 and ensuring that the first connecting rod 4 is stably in the retracted state.

[0038] When the first connecting rod 4 is retracted, the second telescopic rod 42 is rotated so that the locking block 421 is located in the position where the locking groove 412 at the lower end is connected to the slide groove 411, and the second telescopic rod 42 is pushed to move toward the inside of the first telescopic rod 41. When the locking block 421 slides to the inside of the locking groove 412 connected to the upper end of the slide groove 411, the second telescopic rod 42 is rotated so that the locking block 421 slides to a position in the upper end locking groove 412 that is not connected to the slide groove 411, and the position of the second telescopic rod 42 is locked, completing the retraction of the first connecting rod 4, while ensuring that the first connecting rod 4 is stably in the retracted state.

[0039] The second connecting rod 6 includes a second telescopic component and a second connecting end. The second telescopic component has the same structure as the first telescopic component. There are two second connecting ends, both of which are frustum-shaped. One of the second connecting ends is integrally connected to an end of the first telescopic rod in the second telescopic component away from the second telescopic rod, and the other second connecting end is integrally connected to an end of the second telescopic rod in the second telescopic component away from the first telescopic rod. The diameter of the second connecting end at the outer end is smaller than the diameter at the inner end.

[0040] like Figure 4 As shown, the connecting member 5 includes a first cylindrical portion 51 and a second cylindrical portion 52. The outer diameter of the first cylindrical portion 51 is larger than the outer diameter of the second cylindrical portion 52. A through hole 54 is provided inside the first cylindrical portion 51. The through hole 54 extends into the second cylindrical portion 52. The through hole 54 is set through the second cylindrical portion 52. The length of the through hole 54 is less than or equal to the length of the liquid outlet tube 82 of the Marsh funnel 8. Three mounting grooves 53 are provided on the upper wall of the first cylindrical portion 51. The first connecting rod 4 is clamped on the connecting member 5 by extending the first connecting end into the mounting groove 53. The side wall of the first connecting end abuts against the notch of the mounting groove 53 set on the upper wall of the first cylindrical portion 51, and there is friction, so that the first connecting end can be tightly installed in the mounting groove 53. The lower wall of the first cylindrical portion 51 is also provided with three mounting grooves. The notch of the mounting groove set on the lower wall of the first cylindrical portion 51 abuts against the side wall of the second connecting end, and there is friction, so that the second connecting end can be tightly installed in the mounting groove 53.

[0041] The switch plate 55 is hinged to one end of the second cylindrical portion 52 away from the first cylindrical portion 51 . The switch plate 55 and the second cylindrical portion 52 are locked by buckling. The axis of the hinge shaft between the switch plate 55 and the second cylindrical portion 52 is perpendicular to the axis of the second cylindrical portion 52 .

[0042] like Figure 2 As shown, a placement groove 71 is provided on the upper wall of the placement platform 7, and a mud cup is placed inside the placement groove 71, and the inner diameter of the placement groove 71 is greater than or equal to the outer diameter of the supporting upper ring 1; three installation grooves are also provided on the upper wall of the placement platform 7, and the installation grooves are used to install the lower end of the second connecting rod 6. The installation grooves on the placement platform 7 are located on the outside of the placement groove 71, and the notches of the installation grooves on the placement platform 7 are in contact with the side wall of the second connecting end set at the lower end of the second connecting rod 6, and there is friction; the weight of the placement platform 7 matches the weight of the Marsh funnel 8 plus the maximum drilling fluid contained therein, and the weight of the placement platform 7 is preferably greater than 2kg.

[0043] The operating principle of the Magnitogorsk funnel auxiliary device provided in this embodiment is as follows:

[0044] (1) During operation: the first connecting rod 4 is elongated and locked, and the first connecting end is installed in the mounting groove 53 on the upper wall of the connecting member 5, and the second connecting ends on both sides of the second connecting rod 6 are respectively installed in the mounting grooves on the lower wall of the connecting member 5 and the mounting grooves on the upper wall of the placement platform 7. After the auxiliary device provided in this embodiment is installed, the Marsh funnel 8 filled with drilling fluid is placed in the support frame, the outer wall of the cone portion 81 contacts the inner wall of the support upper ring 1, and the liquid outlet pipe 82 extends into the through hole 54 of the connecting member 5. At this time, the switch plate 55 and the second cylindrical portion 52 are in a locked state, the outlet end of the Marsh funnel 8 abuts against the upper wall of the switch plate 55, and the handle 83 is located at the accommodating port 3. Then, the mud cup is placed in the placement groove 71 of the placement platform 7, and the stopwatch is pressed while the switch plate 55 is opened. When the drilling fluid in the mud cup flows to the 946mL scale line, the switch plate 55 is closed and the stopwatch is stopped at the same time. The time recorded by the stopwatch is the viscosity of the test.

[0045] (2) During storage and placement: When the auxiliary device provided in this embodiment has finished working, the first connecting rod 4 is pulled out from the connecting member 5, and then the upper end of the second connecting rod 6 is pulled out from the connecting member 5 and the lower end is pulled out from the placement platform 7, so that the first connecting rod 4 and the second connecting rod 6 are shortened to the shortest state and locked, and the support bracket is inverted and placed in the placement groove 71, and then the connecting member 5 is cleaned and placed in the support bracket together with the second connecting rod 6.

[0046] This embodiment not only ensures contactless measurement of drilling fluid viscosity and ensures the health of technicians, but also the entire device has a simple structure. By setting the weight of the placement platform 7 to match the weight of the Marsh funnel 8 and the drilling fluid contained therein, the stability can be improved. The volume of the entire device when stored is almost half of the volume when working, which greatly reduces the volume of the device when stored and reduces the storage space.

[0047] Finally, it should be noted that the above content is only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Simple modifications or equivalent substitutions of the technical solution of the utility model by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the utility model.
