Description

Technical Field

[0001] The utility model relates to the technical field of valve disassembly, in particular to a disassembly tool for the valves of a large gas engine. Background Art

[0002] The function of the valve is to input air into the engine and discharge the exhaust gas after combustion. From the perspective of engine structure, it is divided into intake valve and exhaust valve. The function of the intake valve is to suck air into the engine and mix it with fuel for combustion; the function of the exhaust valve is to discharge the exhaust gas after combustion and dissipate heat;

[0003] In the oil field, large gas engines are widely used in power generation and compression. During their maintenance, especially overhaul, most of them use common tools on the market.

[0004] In order to further understand the valve disassembly technology field in the prior art, after searching, the Chinese patent with the announcement number: CN213352317U discloses a multifunctional valve disassembly and assembly device for a large gas engine. The utility model includes a pressure rod and a fixed screw rod. One end of the pressure rod is connected to one end of the fixed screw rod through a fixing member. The other end of the fixed screw rod is threaded and matches the cylinder head spark plug seat sleeve. A valve spring compression sleeve plate that can be mounted on the valve and compress the valve spring is suspended on the pressure rod.

[0005] After exploration and analysis, the patent has the following disadvantages when actually used:

[0006] The utility model presses down the pressure rod, and squeezes the valve by the spring compression sleeve to remove the spring of the valve, so as to disassemble the valve. This method is time-consuming and labor-intensive, and requires the staff to press down hard, which increases the safety hazard problem. In addition, each group of cylinders is usually provided with four valves, and this utility model can only disassemble one valve at a time, which increases the time cost of disassembly. Utility Model Content

[0007] In view of the technical problem that the existing utility model presses down the pressure long rod and squeezes the valve by the spring compression sleeve to remove the spring of the valve and disassemble the valve, this method is time-consuming and labor-intensive, and requires the staff to press down hard, which increases the safety hazard problem. In addition, each group of cylinders is usually provided with four valves, and this utility model can only disassemble one valve at a time, which increases the time cost of disassembly. The utility model provides a disassembly tool for the valves of large gas engines.

[0008] The technical solution adopted by the utility model is: a disassembly tool for a large gas engine valve includes a servo motor, a driving shaft of the servo motor is fixedly installed with a threaded rod, a nut is threadedly connected to the threaded rod, a receiving rod is fixedly installed on the nut, an array of receiving sleeves is provided on the receiving rod, and a conical column is provided on the receiving sleeve.

[0009] Furthermore, an array of support beams is fixedly mounted on the nut, a protective tube is fixedly connected to the other end of the support beam, and a handle is fixedly connected to the outside of the servo motor. By adopting the above technical solution, the support beam can support the protective tube.

[0010] Furthermore, there are three receiving sleeves, each of which is provided with a first threaded hole and a third threaded hole, and the receiving rod is provided with a second threaded hole and a fourth threaded hole. By adopting the above technical solution, it can be used in conjunction with bolts.

[0011] Furthermore, the receiving sleeve is provided with a bolt, and the bolt passes through the third threaded hole and the fourth threaded hole and is threadedly connected to the receiving rod. By adopting the above technical solution, it is possible to thread the receiving sleeve on the receiving rod, which is convenient for disassembly and fixation.

[0012] Furthermore, the outside of the receiving sleeve is fixedly connected to the top of the conical column, and the outside of the conical column is fixedly connected to the support beam. By adopting the above technical solution, a protective tube can be provided on the outside of the conical column to prevent the spring of the valve from being ejected and causing a safety hazard to the human body when the conical column is pressed down.

[0013] Furthermore, a connecting sleeve is fixedly installed on the end of the receiving rod, and an anti-slip sleeve is fixedly installed on the inner wall of the connecting sleeve. By adopting the above technical solution, the anti-slip sleeve can be fitted with the outer side of the receiving rod, which can play an anti-slip role and prevent the receiving sleeve from slipping out of the receiving rod when not in use.

[0014] Furthermore, the first threaded hole and the third threaded hole both pass through the receiving sleeve, and the second threaded hole and the fourth threaded hole both pass through the receiving rod. By adopting the above technical solution, it is possible to achieve a bolt passing through the first threaded hole and the third threaded hole to detachably fix the receiving sleeve and the receiving rod, and this is true for both the second threaded hole and the fourth threaded hole.

[0015] The beneficial effect of the utility model is as follows: compared with the prior art, in the utility model, the rotation of the threaded rod will drive the nut to move downward, so that the bottom end face of the nut can be used to squeeze the valve bottom ring to disassemble the valve, and when the nut moves downward, the conical column will also move downward to squeeze the valve bottom ring, so that four valves can be disassembled at the same time, and the conical column can be rotated to a position opposite to the nut by rotating the receiving sleeve, and the conical column opposite to the nut will not contact the valve, and the number of conical columns used for valve disassembly can be selected one by one. This method is simple and easy to operate, does not require manual squeezing to disassemble the valve, reduces safety hazards, and can also disassemble four valves at the same time, saving disassembly time and cost, and can also disassemble the valves one by one, which is more flexible to use.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] The following is combined with Figure 1-4 The utility model is further described.

[0024] In order to solve the problems existing in the background technology, the present application proposes the following technical solutions: a disassembly tool for a large gas engine valve includes a servo motor 2 (the specific model and power of the servo motor 2 in the utility model can be set according to actual usage and personal cost), a handle 1 is fixedly installed on the outside of the servo motor 2, and when in use, the handle 1 can be held by hand to support the servo motor 2, a threaded rod 6 is fixedly installed on the drive shaft of the servo motor 2, a nut 3 is threadedly connected to the threaded rod 6, and the length of the nut 3 is 1 / 2 of the threaded rod 6, and an array of support beams 5 is fixedly installed on the outside of the nut 3. There are four support beams 5, and the specific number of settings can be determined according to actual usage. The other end of the support beam 5 is fixedly connected to a protective tube 4 (the support beam 5 supports the protective tube 4), and the protective tube 4 is cylindrical and has a cavity structure inside. The purpose is to prevent the valve spring from being pushed out and accidentally injuring the staff during use.

[0025] Furthermore, a receiving rod 12 is fixedly mounted on the nut 3, and three receiving sleeves 8 are slidably mounted on the receiving rod 12. A conical column 13 is provided on the receiving sleeve 8. Specifically, the outside of the receiving sleeve 8 is fixedly connected to the top of the conical column 13. The top of the conical column 13 is circular and the bottom is conical. The purpose is to better press against the valve so that the valve can be disassembled. At the same time, the outer sides of the three conical columns 13 are fixedly connected to the support beam 5.

[0026] In addition, a first threaded hole 9 and a third threaded hole 14 are respectively provided on the receiving sleeve 8, and a second threaded hole 10 and a fourth threaded hole are provided on the receiving rod 12. Specifically, the end diameters of the first threaded hole 9, the second threaded hole 10, the third threaded hole 14 and the fourth threaded hole are consistent, and the first threaded hole 9 and the third threaded hole 14 all penetrate the receiving sleeve 8, and the second threaded hole 10 and the fourth threaded hole all penetrate the receiving rod 12, so that they can be threadedly fixed by bolts 7. Bolts 7 are provided on the receiving sleeve 8, and the bolts 7 penetrate the third threaded hole 14 and the fourth threaded hole and are threadedly connected to the receiving rod 12. The fourth threaded hole in the utility model is blocked by the third threaded hole 14, and it is sufficient to know where the position is. Usually, four valves are provided. If all four valves are required To disassemble, you only need to start the servo motor 2. The drive shaft of the servo motor 2 will rotate to drive the threaded rod 6 to rotate. At this time, the nut 3 will move downward, and the bottom of the nut 3 will be squeezed with the bottom ring of the valve, so that the valve can be disassembled. It is emphasized that the other three conical columns 13 should be horizontal with the nut 3 before the four valves can be disassembled at the same time. If only one or two of the valves need to be disassembled, the receiving sleeve 8 can be rotated to the two sides of the receiving rod 12, and then the receiving sleeve 8 is fixed to the receiving rod 12 by the bolt 7 passing through the first threaded hole 9 and the second threaded hole 10. At this time, the conical column 13 will be installed back to back with the nut 3, so that when the nut 3 moves downward, the conical column 13 rotated to the top of the receiving rod 12 will not cause squeezing with the valve.

[0027] A connecting sleeve 11 is fixedly installed at the end of the receiving rod 12. The connecting sleeve 11 is made of stainless steel. An anti-slip sleeve is fixedly installed on the inner wall of the connecting sleeve 11. The material of the anti-slip sleeve can be silicone, which plays an anti-slip role. It can block the receiving sleeve 8 to prevent the receiving sleeve 8 from sliding out along the receiving rod 12 when not in use. If the receiving sleeve 8 and the conical column 13 need to be repaired or replaced, the connecting sleeve 11 can be pulled out forcefully.

[0028] The specific working principle of the utility model is as follows:

[0029] First, the bolt 7 passes through the third threaded hole 14 and the fourth threaded hole to thread the receiving sleeve 8 onto the receiving rod 12 (the conical column 13 and the nut 3 are in a horizontal state at this time), and the servo motor 2 is started. The rotation of the drive shaft of the servo motor 2 will drive the threaded rod 6 to rotate, and the rotation of the threaded rod 6 will drive the nut 3 to move downward. The bottom end surface of the nut 3 can squeeze the bottom ring of the valve, and the valve can be disassembled. When the nut 3 moves downward, the receiving rod 12 and the receiving sleeve 8 move downward at the same time. At this time, the conical column 13 will also move downward to squeeze the bottom ring of the valve, and the four valves can be disassembled at the same time. Disassembly is completed. After that, the rotation direction of the servo motor 2 is changed to the opposite direction of the previous rotation, and the nut 3 can be moved upward. The operation is simple and does not require manual squeezing, which reduces the workload of the staff. If there is no need to disassemble the four valves at the same time, only the unused conical column 13 needs to be rotated to a position opposite to the nut 3 by rotating the receiving sleeve 8, and the receiving sleeve 8 is threadedly fixed to the receiving rod 12 by the bolt 7 passing through the first threaded hole 9 and the second threaded hole 10. In this way, the conical column 13 opposite to the nut 3 will not contact the valve, and the conical columns 13 to be used can be selected one by one.
