Inspection typically involves two parts of work: (1) the effectiveness of the selected part of the engine is judged by the electric motor barring, but the electric motor barring is completely carried out by experience, and whether the actual barring process (such as the barring number of turns) is finished or not cannot be confirmed; (2) the engine and parts connected with the load at the rear end of the engine are periodically disassembled and inspected, but the underground execution system is usually hoisted to the ground for detection on an underground operation platform such as oil drilling, and the mode is high in time consumption and high in labor consumption.

In addition, the inspection result is usually filled in the record ledger by an operator, and a supervisor cannot confirm the inspection state and authenticity in time, even the condition that the false ledger such as inspection is not actually carried out appears.

Detailed Description

The invention will be further illustrated by the following examples in conjunction with the accompanying drawings:

the spring motor a shown in fig. 1 and 2 is a mature spring motor in the prior art, and mainly comprises a rotating shaft 1, a rotating gear 2, a driving gear 3, a spring 4, a main shaft 5, a release mechanism 6, a flywheel driving gear 7, a threaded sleeve 8, a front cover 9, a rear cover 10, a ratchet 11, a ratchet block 12 and the like. The screw sleeve 8 and the main shaft 5 form a screw-nut pair. A fork groove 3a is formed in the left section of the driving gear 3, an annular shaft shoulder 8a is arranged outside the threaded sleeve 8, the annular shaft shoulder 8a penetrates through the fork groove 3a to be connected with the threaded sleeve 8, and the left end of the spring 4 abuts against the annular shaft shoulder 8 a. When the driving gear 3 rotates, the threaded sleeve 8 rotates along with the driving gear 3 under the action of the fork groove 3a, and meanwhile, the threaded sleeve 8 can also move rightwards along the fork groove 3a when the main shaft 5 cannot rotate, so that the energy storage is realized by compressing the spring 4. The flywheel driving gear 7 and the ratchet wheel 11 are fixed together and then form a screw-nut pair with the main shaft 5.

The conventional spring motor is also called a mechanical starter because it rotates the movable disk shaft 1 to start the engine. The steps when it is used to start an engine are as follows:

firstly, a ratchet block 12 is put down through a release mechanism 6, the ratchet block 12 is in contact with a ratchet wheel 11, a rotating rotary shaft 1 drives a driving gear 3, a threaded sleeve 8 and a main shaft 5 to rotate together through a rotary gear 2, and when the main shaft 5 rotates, the ratchet wheel 11 pushes a flywheel driving gear 7 to move leftwards linearly until the flywheel driving gear 7 is meshed with a flywheel gear ring 14 of an engine because the ratchet wheel 11 is locked by the ratchet block 12 and cannot rotate;

secondly, continuously rotating the rotating shaft 1, wherein the main shaft 5 cannot rotate at the moment, the driving gear 3 drives the threaded sleeve 8 to rotate, and meanwhile, the threaded sleeve 8 linearly moves rightwards and compresses the spring 4 to realize energy storage;

and thirdly, lifting the ratchet block 12 through the release mechanism 6, disengaging from the ratchet wheel 11, releasing the locking of the ratchet wheel 11, instantly realizing high-speed rotation of the main shaft 5 under the action of the restoring force of the spring 4, and driving a flywheel gear ring 14 of the engine to rotate at high speed through the flywheel driving gear 7 to realize the starting of the engine.

The above descriptions are prior arts, and are not described herein.

Referring to fig. 1 to 3, the spring motor with polling function of the present invention is added with a turning circle number collecting mechanism for the spring motor a and a turning moment collecting mechanism for the spring motor a based on the existing spring motor.

The method specifically comprises the following steps: the turning circle number acquisition mechanism mainly comprises a proximity switch 15, a counter 16 and a signal wire 13. The proximity switch 15 is mounted on the front cover 9 for collecting the rotation information of the turning gear 2, or the proximity switch 15 is mounted on the front cover 9 for collecting the rotation information of the driving gear 3, or the proximity switch 15 is mounted on the rear cover 10 for collecting the rotation information of the ratchet wheel 11, but the invention is not limited thereto, as long as the turning gear position of the spring motor a can be collected. The proximity switch 15 is connected to the counter 16 via the signal line 13, so that the number of turning turns of the spring motor a is obtained.

The barring torque acquisition mechanism preferably adopts a torque sensor or a torque wrench, and the torque sensor or the torque wrench is installed on the turning shaft 1 and is used for acquiring a torque value of the turning shaft 1.

The method for polling by using the spring motor with polling function comprises the following steps:

firstly, a ratchet block 12 is put down through a release mechanism 6, the ratchet block 12 is in contact with a ratchet wheel 11, a rotating disc moving shaft 1 drives a driving gear 3 and a main shaft 5 to rotate together through a disc moving gear 2, and when the main shaft 5 rotates, the ratchet wheel 11 is locked by the ratchet block 12 and cannot rotate, and the ratchet wheel 11 pushes a flywheel driving gear 7 to move leftwards linearly until the flywheel driving gear is meshed with a flywheel gear ring 14 of an engine. Exactly the same procedure as the first step when the spring motor is used to start the engine.

Secondly, the ratchet block 12 is lifted up through the release mechanism 6 to be separated from the ratchet wheel 11, and the locking of the ratchet wheel 11 is released; the ratchet wheel 11 is unlocked in advance, and in the process of subsequently rotating the rotating shaft 1, the spring 4 does not store energy any more.

And thirdly, continuously rotating the rotary shaft 1, and driving a flywheel gear ring 14 of the engine to rotate through the flywheel driving gear 7. Since the ratchet wheel 11 is unlocked in advance, the flywheel ring gear 14 of the engine can rotate together with the main shaft 5 in the process of continuing to rotate the rotating shaft 1.

In first step to third step, the barring number of turns collection mechanism gathers in real time and transmits spring motor A's barring number of turns to monitor, the record to the barring number of turns, through comparing with the barring number of turns that predetermines, thereby judge whether the barring process in patrolling and examining is accomplished.

Meanwhile, the barring moment acquisition mechanism acquires and transmits the moment value of the barring shaft 1 in real time, monitors and records the moment value, and compares the moment value with a preset moment range value to judge whether the engine and parts connected with the load at the rear end of the engine in the routing inspection are abnormal or not. Because the dynamic resistance fluctuation range of the engine disc is small, and the resistance fluctuation range of parts connected with the load at the rear end of the engine is also small when the parts are in idle load, the torque N fluctuation range of the rotating disc moving shaft 1 is small when the spring motor is used for carrying out disc turning. When the fluctuation range of the torque N exceeds a normal value, it can be determined that an abnormal condition occurs in the engine or a component connected to the load at the rear end of the engine.

The abnormal conditions of the engine and parts connected with the load at the rear end of the engine comprise damage, falling, clamping stagnation, looseness and the like.
