Description

Technical Field

[0001] This utility model relates to the field of mud pump technology, specifically to a mud pump spacer ring fixing device. Background Technology

[0002] Mud pumps are key equipment in drilling operations, primarily used to transport drilling fluid (mud) into the wellbore, serving functions such as cooling the drill bit and carrying cuttings. Spacer rings, as an important component of the mud pump, are installed between the pump casing and the pump shaft to separate different working chambers, ensuring the normal operation of the mud pump.

[0003] Traditionally, spacer rings are fixed with a single bolt. During the operation of a mud pump, the spacer ring is prone to loosening due to the high-speed rotation of the pump shaft and the impact vibration of the mud. This leads to an increase in the gap between the spacer ring and the pump casing, which in turn causes mud leakage and affects the working efficiency of the mud pump. Utility Model Content

[0004] The purpose of this utility model is to provide a mud pump spacer ring fixing device to solve the problems mentioned in the background art. To solve the above technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model relates to a mud pump spacer ring fixing device, comprising:

[0006] The fixing mechanism includes an annular groove, a sliding groove, a sliding plate, a horizontal plate, an inclined column, and a partition plate;

[0007] The annular groove is formed on the inner wall of the pump casing, the sliding groove is formed inside the partition ring, the slide plate is slidably connected in the sliding groove, one end of the horizontal plate is fixedly connected to the middle of the side wall of the slide plate, the inclined column is fixedly connected to the middle of the other side of the slide plate, the inclined column extends out of the side wall of the partition ring and is fitted into the annular groove, the partition plate is fixedly connected in the middle of the sliding groove, and the other end of the horizontal plate slides in the middle of the partition plate.

[0008] Furthermore, a baffle is connected to the end of the horizontal plate, the baffle slides in the sliding groove, and a telescopic column and a spring are connected to the side wall of the baffle. The other end of the telescopic column and the spring are fixedly connected to the side wall of the sliding groove, and the telescopic column passes through the spring.

[0009] Furthermore, the fixing mechanism also includes a fixing ring and a fixing hole;

[0010] The fixing ring is fixedly connected to the inner wall of the pump casing. The surface of the fixing ring is provided with multiple connection holes, and multiple fixing holes are respectively opened on the surface of the spacer ring.

[0011] Furthermore, the horizontal plate has an insertion hole in the middle, and the insertion hole coincides with the position of the fixing hole.

[0012] Furthermore, it also includes a positioning mechanism, which includes a positioning hole, an insertion tube, a beveled ring, and an expansion joint;

[0013] Multiple positioning holes are respectively opened on the side wall of the fixing ring, multiple insertion tubes are respectively fixedly connected to the surface of the spacer ring, the inclined ring is fixedly connected to the top side wall of the insertion tube, and multiple expansion joints are respectively opened at the end of the insertion tube.

[0014] Furthermore, the positioning mechanism also includes threads and screws;

[0015] The thread is formed on the inner wall of the insertion tube end, and the screw is threaded onto the thread.

[0016] Furthermore, a rubber post is embedded inside the cannula, and the top of the rubber post contacts the bottom of the screw.

[0017] This utility model has the following beneficial effects:

[0018] This invention involves pushing a spacer ring into the pump casing from one end. The inclined surface of the column contacts the end of the pump casing, and the column slides into the sliding groove. The inclined surface causes the sliding plate to slide inward, which in turn causes the horizontal plate to slide inward. The horizontal plate causes the baffle to slide inward, compressing the telescopic column and spring. When the side wall of the spacer ring is in contact with the inner wall of the fixed ring, the spring rebounds, causing the baffle to slide outward and the telescopic column to lengthen. The baffle causes the horizontal plate to slide outward, which in turn causes the sliding plate to slide outward. The sliding plate then causes the inclined column to slide out of the side wall of the spacer ring and fit into the ring groove. A screw is then passed through the fixed ring, insertion hole, and fixing hole and tightened with a nut to secure the spacer ring. Even if the screw loosens due to the high-speed rotation of the pump shaft and the impact vibration of the mud, the spacer ring, fitted into the ring groove by the inclined surface, maintains its original position and does not slide. This ensures that the spacer ring remains constant with the pump casing, preventing mud leakage and ensuring the pump's efficiency. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0029] Please see Figure 1-4 As shown, this utility model is a mud pump spacer ring fixing device, comprising:

[0030] The fixing mechanism includes an annular groove 110, a sliding groove 120, a sliding plate 130, a horizontal plate 140, an inclined column 150, and a partition plate 160.

[0031] An annular groove 110 is formed on the inner wall of the pump casing, a sliding groove 120 is formed inside the spacer ring, a slide plate 130 is slidably connected to the sliding groove 120, one end of a horizontal plate 140 is fixedly connected to the middle of the side wall of the slide plate 130, an inclined column 150 is fixedly connected to the middle of the other side of the slide plate 130, the inclined column 150 extends out of the side wall of the spacer ring and is fitted into the annular groove 110, a partition plate 160 is fixedly connected to the middle of the sliding groove 120, and the other end of the horizontal plate 140 slides in the middle of the partition plate 160, moving the spacer ring from the pump casing. One end is pushed in, so that the inclined surface of the inclined column 150 contacts the end of the pump casing. Then, the inclined surface is pressed to make the inclined column 150 slide into the sliding groove 120. The inclined column 150 drives the slide plate 130 to slide inward. The slide plate 130 drives the horizontal plate 140 to slide inward. When the side wall of the partition ring is in contact with the inner wall of the fixed ring 180, the horizontal plate 140 slides outward, driving the slide plate 130 to slide outward. The slide plate 130 drives the inclined column 150 to slide out of the side wall of the partition ring and fit into the ring groove 110, so that the partition ring is fitted into the ring groove 110.

[0032] A baffle 171 is attached to the end of the horizontal plate 140. The baffle 171 slides in the sliding groove 120. A telescopic column 172 and a spring 173 are attached to the side wall of the baffle 171. The other ends of the telescopic column 172 and the spring 173 are fixedly attached to the side wall of the sliding groove 120. The telescopic column 172 passes through the spring 173. The horizontal plate 140 drives the baffle 171 to slide inward and compresses the telescopic column 172 and the spring 173. When the side wall of the partition ring is in contact with the inner wall of the fixed ring 180, the spring 173 rebounds and drives the baffle 171 to slide outward and stretches the telescopic column 172. The baffle 171 drives the horizontal plate 140 to slide outward.

[0033] The fixing mechanism also includes a fixing ring 180 and a fixing hole 190;

[0034] The fixing ring 180 is fixedly connected to the inner wall of the pump casing. The surface of the fixing ring 180 has multiple connecting holes 181 and multiple fixing holes 190 respectively opened on the surface of the spacer ring. The diameter of the connecting holes 181 and the fixing holes 190 is the same. After passing a screw through the fixing ring 180 and the fixing holes 190, it is tightened with a nut to fix the spacer ring inside the pump casing.

[0035] A socket 141 is provided in the middle of the horizontal plate 140. The socket 141 coincides with the position of the fixing hole 190. The screw passes through the fixing hole 190 and the socket 141 at the same time, to prevent the horizontal plate 140 from sliding in the opposite direction and causing the inclined column 150 to slide out of the annular groove 110.

[0036] Working principle: The spacer ring is pushed in from one end of the pump casing, causing the inclined surface of the inclined column 150 to contact the end of the pump casing. The inclined surface then compresses the inclined column 150, causing it to slide into the sliding groove 120. The inclined column 150 drives the slide plate 130 to slide inward, which in turn drives the horizontal plate 140 to slide inward. The horizontal plate 140 drives the baffle 171 to slide inward, compressing the telescopic column 172 and the spring 173. When the side wall of the spacer ring is in contact with the inner wall of the fixed ring 180, the spring 173 rebounds, causing the baffle 171 to slide outward and the telescopic column 172 to stretch. The baffle 171 then drives the horizontal plate 140 to slide outward, and the outward sliding of the horizontal plate 140... The sliding plate 130 slides outward, and the sliding plate 130 drives the inclined column 150 to slide out of the side wall of the partition ring and fit into the ring groove 110, so that the partition ring is fitted into the ring groove 110. After the screw passes through the fixing ring 180, the insertion hole 141 and the fixing hole 190, it is tightened with the nut to fix the partition ring in the pump casing. Even if the screw loosens due to the high speed rotation of the pump shaft and the impact vibration of the mud, the partition ring can still maintain its original position and not slide through the inclined column 150 fitted into the ring groove 110. This keeps the partition ring and the pump casing unchanged and avoids mud leakage, which would affect the working efficiency of the mud pump.

[0037] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes:

[0038] The positioning mechanism includes a positioning hole 210, an insertion tube 220, an inclined ring 230, and an expansion joint 240.

[0039] Multiple positioning holes 210 are respectively opened on the side wall of the fixing ring 180. Multiple insertion tubes 220 are respectively fixedly connected to the surface of the spacer ring. The inclined ring 230 is fixedly connected to the top side wall of the insertion tube 220. Multiple expansion joints 240 are respectively opened at the end of the insertion tube 220. After the insertion tube 220 is aligned with the positioning hole 210, it is inserted. During insertion, the end of the insertion tube 220 is deformed along the inclined surface of the inclined ring 230, thereby narrowing the expansion joint 240. When the insertion tube 220 is inserted into place, the inclined ring 230 extends out of the positioning hole 210. At this time, the deformation of the end of the insertion tube 220 is restored, so that the expansion joint 240 is restored, and the inclined ring 230 is directly stuck on the surface of the fixing ring 180, thus completing the positioning of the spacer ring and automatically aligning the fixing ring 180 and the fixing hole 190.

[0040] The positioning mechanism also includes thread 250 and screw 260;

[0041] Thread 250 is formed on the inner wall of the end of the cannula 220, and screw 260 is threaded onto thread 250. Screw 260 into thread 250 to prevent the end of the cannula 220 from shrinking.

[0042] A rubber column 270 is embedded inside the cannula 220. The top of the rubber column 270 contacts the bottom of the screw 260. Before screwing in the screw 260, the rubber column 270 is embedded in the cannula 220. After screwing in the screw 260, the rubber column 270 is squeezed and deformed so that the rubber column 270 seals the deformation joint 240 and improves the sealing performance.

[0043] Working principle: After aligning the insertion tube 220 with the positioning hole 210, insert it. During insertion, the end of the insertion tube 220 deforms along the inclined surface of the inclined ring 230, thereby narrowing the deformation gap 240. When the insertion tube 220 is inserted in place, the inclined ring 230 extends out of the positioning hole 210. At this time, the deformation of the end of the insertion tube 220 is restored, so that the deformation gap 240 is restored, and the inclined ring 230 is directly stuck on the surface of the fixing ring 180. The rubber column 270 is embedded in the insertion tube 220. The screw 260 is screwed into the thread 250. After screwing in the screw 260, the rubber column 270 is squeezed and deformed, so that the rubber column 270 blocks the deformation gap 240. This can quickly position the spacer ring and automatically align the fixing ring 180 and the fixing hole 190.

Clearly, many modifications and variations can be made based on the content of this specification.
