However, both of the above methods require manual intervention and cannot be adjusted in time, so the effect is poor.

the gear commutator further comprises an input shaft, an output shaft, a middle transmission shaft and four bevel gears, wherein the input shaft and the output shaft are respectively provided with one bevel gear, the upper end and the lower end of the middle transmission shaft are respectively provided with one bevel gear, and the bevel gears arranged on the input shaft and the output shaft are respectively meshed with the two bevel gears at the upper end and the lower end of the middle transmission shaft;
the contact wheel is fixedly arranged on an input shaft of the gear commutator;
an output shaft of the gear commutator is connected with the screw rod through a sleeve, wherein the output shaft is fixedly connected with the sleeve through a bolt, and the screw rod is in sliding connection with the sleeve through matching of prisms and edge holes;
the contact wheel is positioned below the belt, the belt is contacted with the outer side of the contact wheel after being loosened, and the contact wheel rotates under the action of friction force exerted by the belt.
As a further technical scheme, the contact wheel is a component and comprises a driving wheel, a driven wheel, a ring sleeve, a sliding sheet and a tension spring A, wherein the driving wheel is installed on the output shaft through a bearing, the driven wheel is installed on the output shaft through a flat key, the sliding sheet is inserted in the outer edge of the driving wheel in a sliding manner along the radial direction, and the sliding sheet always keeps a moving trend of approaching the axis of the driving wheel under the tension action of the tension spring A;

The invention has the beneficial effects that:
1. the belt of the oil pumping unit has a characteristic when working: when the belt on the oil pumping unit is loosened, the vibration amplitude of the middle part of the belt is increased. The invention skillfully utilizes the characteristic and designs the motor supporting device which can automatically tension the loose belt, when in use, the loose belt is contacted with the outer side of the contact wheel after being loosened, the contact wheel rotates under the action of the friction force exerted by the belt, the rotating motion is converted into the rotating motion of the lead screw through the gear commutator and the sleeve, the position adjustment of the sliding plate is realized through the rotating motion of the lead screw, and the motor and the belt pulley on the sliding plate move towards the direction for tensioning the belt. When the belt is tensioned to a certain degree, the contact time of the belt and the contact wheel is reduced, so that the friction force provided by the belt is not enough to drive the contact wheel to rotate, and the belt stops tensioning.
Therefore, the automatic tensioning device adopts a pure mechanical structure to realize the automatic tensioning of the belt, has no technical principle, has higher working reliability, is rain-proof and dust-proof, is easy to maintain and is more suitable for the pumping unit which operates in a severe field environment compared with the electric control automatic tensioning device which is frequently adopted in the mechanical field.
2. In the invention, the contact wheel is internally provided with the driving wheel and the driven wheel, and the clutch mechanism is arranged between the driving wheel and the driven wheel.
When the loosening degree of the belt is small, the belt is in intermittent contact with the ring sleeve fixed on the outer side of the driving wheel, the contact pressure is small, and the contact time is short, so that the friction force of the belt does little work on the driving wheel, and under the condition, the rotating speed of the ring sleeve and the driving wheel is low, and the sliding sheet cannot extend out of the outer side of the driving wheel.
When the loosening degree of the belt is large, the contact time of the belt and the ring sleeve is prolonged, the contact pressure is increased, and then the acting of the belt on the ring sleeve and the driving wheel is increased.
The advantages of the structure are that: when the belt is slightly loosened and no obvious adverse effect is caused, the driving wheel can rotate along with the running of the belt, but the power can not be transmitted downwards, namely, the action of tensioning the belt can not be performed, and therefore, unnecessary abrasion between the belt and the contact wheel is greatly avoided. When the belt is loosened to a large extent, the driving wheel and the driven wheel rotate together and transmit power to the sliding plate, so that the sliding plate drives the motor and the belt pulley to move, and finally the belt is tensioned again.
3. As a better scheme, the invention also arranges a tension spring B, a sliding sleeve and a locking block in the driving wheel.
Before the belt contacts with the contact wheel, the contact wheel is in a static state, the slip sheet is locked on the slip sleeve by the locking block, and after the belt contacts with the contact wheel, the driving wheel rotates. In the sliding process of the sliding sleeve, when the end part of the locking block is aligned with the locking groove on the driving wheel, the sliding piece can force the end part of the locking block to slide into the locking groove on the driving wheel due to the movement trend of sliding out of the sliding sleeve, so that the sliding sleeve is locked on the driving wheel, the sliding piece is released simultaneously, and the released sliding piece is meshed with the ratchet on the driven wheel to tension the belt.
The advantages of the structure are that: the structure ensures that the requirement on the rotating speed of the driving wheel is higher before the clutch mechanism enters the engaging state, thereby further avoiding unnecessary abrasion between the belt and the contact wheel.

Detailed Description
The invention is further described below with reference to the accompanying drawings:
the first embodiment is as follows:
as shown in fig. 1, the present embodiment includes a base plate 1, a sliding plate 3, a lead screw 2, a gear commutator and a contact wheel 10, the base plate 1 is fixed on the base of the pumping unit, the sliding plate 3 is slidably mounted on the base plate 1 through a dovetail groove structure, and the sliding direction is consistent with the length direction of a belt 11; the lead screw 2 is rotatably mounted on the base plate 1, and the sliding plate 3 is connected with the lead screw 2 through threads and can slide under the driving of the lead screw 2. The above structure is a common structure on various machine tools, and the core function of the structure is to achieve the purpose of moving the motor 4 by rotating the screw rod 2.
As shown in fig. 1, the gear commutator further comprises an input shaft 9, an output shaft 6, an intermediate transmission shaft 8 and four bevel gears 7, wherein the input shaft 9 and the output shaft 6 are respectively provided with one bevel gear 7, the upper end and the lower end of the intermediate transmission shaft 8 are respectively provided with one bevel gear 7, and the bevel gears 7 arranged on the input shaft 9 and the output shaft 6 are respectively engaged with the two bevel gears 7 at the upper end and the lower end of the intermediate transmission shaft 8; the contact wheel 10 is fixedly arranged on an input shaft 9 of the gear commutator; an output shaft 6 of the gear commutator is connected with the lead screw 2 through a sleeve 5, wherein the output shaft 6 is fixedly connected with the sleeve 5 through a bolt, and the lead screw 2 is in sliding connection with the sleeve 5 through matching of prisms and edge holes. The above structure is a motion transmission mechanism from the contact wheel 10 to the lead screw 2.
The above are all technical solutions of the present embodiment, wherein conventional mechanical transmission mechanisms are adopted, but through the combination of these conventional transmission mechanisms, and by utilizing "when the belt 11 on the pumping unit is loosened, the vibration amplitude of the middle part of the belt 11 is increased. "this feature forms a supporting device of the motor 4 which can automatically tension the loose belt 11, when in use, the loose belt 11 contacts with the outer side of the contact wheel 10, the contact wheel 10 rotates under the friction force exerted by the belt 11, the rotation is converted into the rotation of the lead screw 2 through the gear commutator and the sleeve 5, the position of the slide plate 3 is adjusted through the rotation of the lead screw 2, and the motor 4 and the belt pulley 12 on the slide plate 3 move in the direction of tensioning the belt 11. When the belt 11 is tensioned to a certain degree, the contact time of the belt 11 with the contact roller 10 becomes short, so that the friction force provided by the belt 11 is not enough to drive the contact roller 10 to rotate, and the belt 11 stops tensioning.
Therefore, the automatic tensioning device adopts a pure mechanical structure to realize the automatic tensioning of the belt 11, has no technical principle, has higher working reliability, is rain-proof and dust-proof, is easy to maintain and is more suitable for the pumping unit which operates in a severe field environment compared with the electric control automatic tensioning device which is frequently adopted in the mechanical field.
Example two:
the difference between this embodiment and the first embodiment is that the structure of the contact wheel 10 is optimized.
As shown in fig. 2, as a further technical solution, the contact wheel 10 is a component, and includes a driving wheel 13, a driven wheel 14, a ring sleeve 23, a sliding piece 15 and a tension spring a17, the driving wheel 13 is mounted on the output shaft 6 through a bearing 22, the driven wheel 14 is mounted on the output shaft 6 through a flat key, the sliding piece 15 is inserted in the outer edge of the driving wheel 13 in a sliding manner in the radial direction, and the trend of movement towards the axis of the driving wheel 13 is always kept under the tension of the tension spring a 17; ratchets 16 matched with the tail ends of the sliding pieces 15 are machined on the inner sides of the driven wheels 14, and after the sliding pieces 15 are meshed with the ratchets 16, the driving wheels 13 and the driven wheels 14 rotate synchronously; the ring sleeve 23 is fixedly connected to the driving wheel 13 through bolts, and the driven wheel 14 is positioned on the inner side of the ring sleeve 23.
In the above configuration, the provision of the slide piece 15 and the spring corresponds to the provision of a clutch mechanism between the driving pulley 13 and the driven pulley 14.
When the slack degree of the belt 11 is small, the belt 11 is intermittently contacted with the ring sleeve 23 fixed on the outer side of the driving wheel 13, and the contact pressure is small, the contact time is short, so the friction force of the belt 11 does little work on the driving wheel 13, in this case, the rotating speed of the ring sleeve 23 together with the driving wheel 13 is low, and the sliding piece 15 is not enough to extend from the outer side of the driving wheel 13. When the belt 11 is loosened to a greater extent, the contact time between the belt 11 and the ring sleeve 23 is prolonged, the contact pressure is increased, and the work of the belt 11 on the ring sleeve 23 and the driving wheel 13 is increased, in this case, the rotating speed of the ring sleeve 23 and the driving wheel 13 is increased, and the slide piece 15 overcomes the pulling force of the tension spring under the action of centrifugal force, and then extends from the outer side of the driving wheel 13 and is engaged with the ratchet 16 on the outer side of the driven wheel 14.
The advantages of the structure are that: when the belt 11 is slightly slack without significant adverse effects, the driving pulley 13 rotates with the running of the belt 11, but does not transmit power downward, i.e., does not perform an action of tensioning the belt 11, thereby largely avoiding unnecessary wear between the belt 11 and the contact roller 10. When the belt 11 is loosened to a large extent, the driving pulley 13 and the driven pulley 14 rotate together and transmit power to the sliding plate 3, so that the sliding plate 3 drives the motor 4 and the belt pulley 12 to move, and finally the belt 11 is tensioned again.
Example three:
the present embodiment further optimizes the structure of the contact wheel 10 based on the second embodiment.
As shown in fig. 3-5, as a further technical solution, a sliding sleeve 18 is further installed in the driving wheel 13, and both the sliding piece 15 and the tension spring a17 are installed on the sliding sleeve 18; the sliding sleeve 18 is inserted on the driving wheel 13 in a sliding way along the radial direction, and always keeps the moving trend of approaching to the axle center of the driving wheel 13 under the pulling force of another pulling spring B20; the elastic coefficient of the tension spring B20 is greater than that of the tension spring A17; the side of sliding sleeve 18 is provided with the through-hole, and slidable mounting has locking piece 19 in the through-hole, be provided with locked groove 21 with the both ends correspondence of locking piece 19 on gleitbretter 15 and the action wheel 13 respectively.
After adopting the above structure, before the belt 11 contacts the contact wheel 10, the contact wheel 10 is in a static state, the sliding piece 15 is locked on the sliding sleeve 18 by the locking piece 19, after the belt 11 contacts the contact wheel 10, the driving wheel 13 rotates, because the elastic coefficient of the tension spring B20 is larger, compared with the scheme of only arranging the tension spring a17, the driving wheel 13 can enable the sliding sleeve 18 to slide outwards along the radial direction only by reaching a larger rotating speed. During the sliding process of the sliding sleeve 18, when the end of the locking block 19 is aligned with the locking groove 21 on the driving wheel 13, the sliding tendency of the sliding piece 15 sliding out of the sliding sleeve 18 forces the end of the locking block 19 to slide into the locking groove 21 on the driving wheel 13, so as to lock the sliding sleeve 18 on the driving wheel 13, and release the sliding piece 15, and the released sliding piece 15 is engaged with the ratchet 16 on the driven wheel 14 to tension the belt 11.
The advantages of the structure are that: the above-described structure makes the requirement on the rotational speed of the drive pulley 13 higher before the clutch mechanism is brought into the engaged state, thereby further avoiding unnecessary wear between the belt 11 and the contact pulley 10.
In practice, it is necessary to pay attention to the material density of the sliding sleeve 18 and the sliding piece 15, which should be slightly higher, so as to make a timely response after the driving wheel 13 rotates. In addition, the transmission ratio from the spindle 2 to the contact wheel 10 should be as large as possible, i.e. the slower the spindle 2 rotates, the better.
