Description

Technical Field

[0001] The invention relates to a diesel engine in the field of oil drilling, in particular to an installation device for a diesel engine starter motor for oil drilling, belonging to the technical field of well site auxiliary equipment. Background Art

[0002] The advantages of diesel engines are high torque and good economic performance. Each working cycle goes through four strokes: intake, compression, power generation and exhaust. Currently in oil drilling construction, the power of drilling rigs and generators is mostly provided by diesel engines. Drilling diesel engines are heavy equipment and occupy a very important position in the oil drilling operation.

[0003] To make the diesel engine transition from a static state to a working state, the engine's crankshaft must be rotated by external force to make the piston reciprocate, and the combustible mixture in the cylinder burns and expands to do work, pushing the piston downward to rotate the crankshaft. The diesel engine can then run on its own and the working cycle can proceed automatically. Therefore, the whole process from the crankshaft starting to rotate under the action of external force to the engine starting to automatically idle is called engine starting.

[0004] At present, the starting of the diesel engine is powered by the starter motor, and the pinion at the output end of the starter motor meshes with the flywheel sprocket at the end of the crankshaft. When the starter motor fails or needs maintenance, it needs to be removed from the diesel engine for inspection and repair, and then reinstalled on the diesel engine after repair.

[0005] When installing the starter motor, you need to suspend the starter motor and move it toward the end where the flywheel sprocket is located until the fixed end of the starter motor contacts the end face of the motor fixing bracket. Then rotate the starter motor to align the mounting hole of the starter motor with the hole of the motor fixing bracket, and then insert the bolt.

[0006] As the drilling team works in the field, the on-site environment is relatively bad. At present, the installation and removal of the diesel engine starter motor is achieved by manpower and crane at the production site. It is necessary to wait for the crane to arrive. The on-site environment is bad, and it is not convenient for the crane to enter and exit and lift. It takes 3 hours to complete the operation with four people. It not only increases the maintenance cost, but also wastes time and effort. The labor intensity of the workers is high, the quality requirements of the operators are high, and there are certain safety hazards in the operation process.

[0007] If the diesel engine stops operating, the drilling system will lose power. If it cannot be started for a long time, it will cause the risk of complex situations underground. Summary of the invention

A small hole is provided on the right side wall of the right support 9, and the inner end of the limiting screw 10 is inserted into the sector gear concave arc groove 28a through the small hole to limit the sector gear 28, ensuring that the sector gear 28 can only swing around its own axis.

[0059] The bottom of the right support concave arc groove 9a is connected with the right support long groove 9c, and the right support long groove 9c contains a rack 29, and the left and right sides of the rack 29 are matched with the two sides of the right support long groove 9c so that the rack 29 can only move forward and backward. The rack 29 is meshed with the bottom of the sector gear 28; the bottom of the rack 29 is connected to the top of the guide block 31 as a whole, and the left and right sides of the guide block 31 extend downward to form a guide groove opening downward, and a rack position adjustment rod 30 extending in the front-back direction is embedded in the guide groove, and the rack position adjustment rod 30 can only move forward and backward to control the lifting and lowering of the rack 29.

[0060] The top of the rack position adjustment rod 30 is a plane, and the bottom of the rack position adjustment rod 30 is provided with two groups of adjustment rod grooves 30b and downwardly protruding adjustment rod protrusions 30a along the length direction, and the adjustment rod grooves 30b are respectively transitioned to the adjustment rod protrusions 30a through inclined surfaces. The front end of the rack position adjustment rod 30 extends out from the notch of the front stopper 40 of the support groove and is provided with an adjustment rod hook 30c, which facilitates pulling the rack position adjustment rod 30 in the front and rear directions through the adjustment rod hook 30c.

[0061] The right screw rod 32 is located in the notch of the right support groove 49 and below the rack position adjustment rod 30. Two movable screw blocks 33 are screwed onto the right screw rod 32. The tops of the two movable screw blocks 33 are respectively located below the two adjustment rod grooves 30b. The left and right sides of the two movable screw blocks 33 are flush with the two side walls of the right support long groove 9c, so that the movable screw blocks 33 can only translate in the front-to-back direction.

[0062] The rear end head of the right screw rod 32 is rotatably supported in the rear stopper 34 of the right support groove, and the rear stopper 34 of the right support groove is fixed to the rear end of the right support groove 49 by screws. The front end head of the right screw rod 32 is rotatably supported in the front stopper 40 of the right support groove, and the front stopper 40 of the right support groove is fixed to the front end of the right support groove 49 by screws, so that the right screw rod 32 can only rotate but cannot move axially.

[0063] The front end head of the right screw rod 32 is fixed with a right handle 46 through a key 47. A handle fixing nut 45 is pressed on the center of the outer end surface of the right handle 46. The handle fixing nut 45 is screwed on the front end threaded section of the right screw rod 32. A handle extension rod 44 is hinged on the circumference of the right handle.

[0064] By rotating the right handle 46 and the right screw rod 32 through the handle extension rod 44, the two movable screw blocks 33 are driven to move forward and backward synchronously. The left and right sides of the two movable screw blocks 33 are respectively fixedly connected to the upper guide block 31 through the connecting block 33a. When the two movable screw blocks 33 move forward and backward, the guide block 31 and the rack 29 are driven to move forward and backward.

[0065] In the initial state, the adjusting rod groove 30 b matches with the top of the two moving screw blocks 33 , and the rack position adjusting rod 30 is at a low position, so that the rack 29 and the sector gear 28 are out of meshing state.

[0066] The rack position adjusting rod 30 is pushed backwards so that the adjusting rod protrusion 30a matches with the tops of the two moving screw blocks 33. At this time, the rack position adjusting rod 30 rises to a high position so that the rack 29 and the sector gear 28 are meshed.

[0067] When the rack 29 and the sector gear 28 are in meshing state, the right screw 32 is rotated by the right handle 46, and the right screw 32 and the moving screw block 33 drive the rack 29 to move through spiral transmission. The rack 29 and the sector gear 28 form a gear rack transmission, so that the sector gear 28 swings within a certain range.

[0068] The rack position adjustment lever 30 is used to adjust the meshing or non-meshing state of the rack 29 and the sector gear 28 according to the working conditions. When the diesel engine starter motor does not need to rotate in the diesel engine crankshaft direction during assembly, it should be ensured that the rack 29 and the sector gear 28 are in a non-meshing state first, and other states can be adjusted according to working needs.

[0069] Buckles 28c are respectively screwed on the two sector edges of the sector gear 28, and the middle part of the tie belt is passed around the circumference of the diesel engine starter motor and the two ends are respectively fixed on the buckles 28c. This facilitates the sector gear 28 to drive the diesel engine starter motor to rotate slightly, and facilitates the alignment of the mounting holes on the starter motor with the mounting holes on the motor fixing support frame, and the fixing bolts are installed.

[0070] The steps for installing a diesel engine starter motor are as follows: S1. Fix the device on the side of the diesel engine base, specifically including: fixing the two rear support leg fixing clips 14 on the inclined wall hole grooves of the diesel engine base respectively, and supporting the lower ends of the two front support leg lower rods 1 on the bottom plate of the diesel engine base through the front support leg pads 48 respectively; adjusting the two front support leg adjustment rods 2 and the two rear support leg adjustment rods 17 so that the left support groove 18 and the right support groove 49 are in a horizontal state, and the height matches the height of the motor fixed support frame.

[0071] S2. Pull the rack position adjustment rod 30 forward, so that the adjustment rod protrusion 30a is out of contact with the moving screw block 33, that is, the moving screw block 33 is located in the adjustment rod groove 30b, and the rack 29 and the guide block 31 fall to a low position, so that the rack 29 and the sector gear 28 are in a non-meshing state; S3, then the front and rear adjustment hand wheel 3 is rotated forward to drive the left screw rod 43 to rotate forward. Since the left screw rod 43 is fixed in the left support groove 18 by the support groove front block 40 and the support groove rear block 34, it can only rotate. The screw hole at the lower end of the left support 5 cooperates with the left screw rod 43. Therefore, when the left screw rod 43 rotates forward, the left support 5 moves forward along the left support groove 18; at the same time, it drives the right support 9 to move forward synchronously along the right support groove 49; and the position of the lateral movable support 7 is moved forward, so as to avoid interference with the diesel engine exhaust pipe and other components above when the diesel engine starter motor is hoisted.

[0072] S4. Lift the diesel engine starter motor by simple tools such as a holding pole and a hand winch and place it on the transverse movable support 7. Fix the right end of the starter motor with a binding belt, and fix the two ends of the binding belt on the buckles 28c at the two ends of the sector gear 28.

[0073] S5. Reversely rotate the front and rear adjustment hand wheel 3, and through the reverse rotation of the left screw rod 43, the left support 5 and the right support 9 are synchronously translated backward, so that the diesel engine starter motor gradually approaches the diesel engine body until the starter gear of the starter motor is aligned with the hole on the diesel engine motor fixed support frame.

[0074] S6. The worm handwheel 39 on the worm shaft 36 rotates forward. The worm shaft 36 and the worm wheel 22 drive the worm wheel shaft 13 to rotate through the transmission of the worm and worm wheel. Therefore, the transverse movable support 7 matched with the worm wheel shaft 13 moves to the right through the screw drive, and the diesel engine starter motor placed on the transverse movable support 7 also moves to the end where the flywheel sprocket is located on the right side, so that the motor pinion passes through the motor seat hole until the flange of the starter motor contacts the flange of the motor fixed support. At this time, the motor pinion is meshed with the flywheel sprocket of the diesel engine.

[0075] S7. If the mounting holes on the starter motor flange are aligned with the mounting holes on the motor mounting bracket flange, directly insert the bolts to secure them.

[0076] If the mounting holes on the starter motor flange do not align with the mounting holes on the motor mounting bracket flange, proceed to the next step.

[0077] S8. Push the rack position adjustment rod 30 backward so that the protrusion 30a of the adjustment rod matches with the top of the two movable screw blocks 33. At this time, the rack position adjustment rod 30 rises to the high position, so that the rack 29 rises and meshes with the sector gear 28.

[0078] S9. Turn the right handle to drive the right screw 32 to rotate. Since the right screw 32 is axially positioned, the two movable screw blocks 33 drive the upper rack 29 and the guide block 31 to translate back and forth, and the sector gear 28 swings at a certain angle, driving the diesel engine starter motor to rotate within a certain range until the mounting hole on the starter motor flange is aligned with the mounting hole on the motor fixed support flange, and then insert the bolts to fix it.
