Detailed Description
The first embodiment is as follows:
embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
As shown in fig. 1, the present embodiment includes an upper plate 2, a lower plate 4, a lead screw 3, and a wedge assembly; one end of the screw rod 3 is provided with a rotary sleeve 1 through a clamp spring, and the other end of the screw rod 3 is fixedly provided with a hand wheel 14; one end parts of the upper plate 2 and the lower plate 4 are respectively hinged on the upper side and the lower side of the rotary sleeve 1; the wedge assembly is slidably mounted between the upper plate 2 and the lower plate 4, and the wedge assembly is driven by the lead screw 3 to move between the upper plate 2 and the lower plate 4. During installation, the lower plate 4 is fixedly installed on a base of the oil pumping unit, and the motor is fixedly installed on the upper plate 2. During the use, rotatory hand wheel 14 makes lead screw 3 rotatory, drives the motion of wedge subassembly then to adjust the contained angle of upper plate 2 and hypoplastron 4.
As shown in fig. 1, the wedge assembly further includes an upper housing 10, a lower housing 16, an upper support arm 12, a lower support arm 15, a nut a17 and a nut B18, two different threads, called a normal thread 7 and a reciprocating thread 9, are machined on the lead screw 3, the normal thread 7 and the reciprocating thread 9 are both single-start threads and have the same pitch, a nut a17 is installed on a section where the normal thread 7 is located, a nut B18 is installed on a section where the reciprocating thread 9 is located, one end portions of the upper housing 10 and the lower housing 16 are respectively hinged on the upper side and the lower side of the nut a17, the upper housing 10 and the lower housing 16 are respectively in sliding fit with the upper plate 2 and the lower plate 4 through a plane, two ends of the upper support arm 12 are respectively hinged on the upper side of the nut B18 and the lower side of the upper housing 10, and two ends of the lower support arm 15 are respectively hinged on the.
When the tension of the belt is adjusted, the movement amplitude required by the motor is small, under the condition, the wedge-shaped assembly-based angle adjusting mechanism is designed, the wedge-shaped assembly slides between the upper plate 2 and the lower plate 4 by rotating the lead screw 3, so that the included angle between the upper plate 2 and the lower plate 4 is adjusted, the position of the motor is finely adjusted in an angle adjusting mode, and the tension of the belt is adjusted. In addition, in the invention, the upper side and the lower side of the wedge-shaped component are respectively in sliding fit with the upper plate 2 and the lower plate 4 through the large planes, so that the reliable support of the motor can be ensured in the adjusting process.
It should be noted that the reciprocating screw thread 9 is a special screw thread for providing reciprocating motion, and belongs to the prior art. In the field of mechanical equipment, a screw 3 with a reciprocating thread 9 is generally called a reciprocating screw 3, and the screw 3 can reciprocate a slide block (in the invention, a nut B18 is equivalent to a slide block) on the screw 3 without changing the rotating direction of the screw 3. Whereas the conventional thread 7 described above generally refers to all common, standard or non-standard threads that cannot provide a reciprocating motion.
The working principle of the invention is as follows:
1. when adjusting the belt tensile force, rotate lead screw 3, the rotary motion of lead screw 3 passes through the linear motion that the screw thread converted into nut A17 and nut B18 to drive wedge subassembly global motion, the realization is to the regulation of contained angle between upper plate 2 and hypoplastron 4.
2. When the belt is replaced, the lead screw 3 is turned until the nut a17 moves to close to one end of the rotating sleeve 1 and disengages from the thread, at the same time as the nut B18 also moves to the left in fig. 1 to the limit position and starts moving in the opposite direction under the effect of the reciprocating thread 9. Thus, the relative movement of the nut B18 and the upper and lower cases 10 and 16 forces the upper and lower arms 12 and 15 to lift up, so that the upper plate 2 can be turned over at a large angle relative to the lower plate 4, thereby enlarging the moving range of the motor and facilitating the assembly and disassembly of the belt. It should be noted here that after the nut a17 is disengaged from the threads, it still needs to slide to the left in fig. 1 during the process of lifting the upper and lower arms, so as to ensure that the included angle between the upper shell 10 and the lower shell 16 is smoothly increased.
After the belt is replaced, the screw rod 3 is continuously rotated in the same direction, so that the nut B18 turns back again, the upper support arm 12 and the lower support arm 15 are gradually retracted, the upper support arm 12 and the lower support arm 15 are restored to the position state shown in FIG. 1 again, if the belt is still in a loose state at the moment, the screw rod 3 can be continuously rotated in the reverse direction, and then the nut A17 is screwed on the conventional thread 7 again under the pressing of the spring 5 and the sliding ring 6, so that the belt is tensioned.
As shown in fig. 1, the upper plate 2 and the upper shell 10 are slidably engaged with each other through a dovetail-shaped engagement structure 8, and the lower plate 4 and the lower shell 16 are slidably engaged with each other through a dovetail groove and a dovetail rib. Draw upper plate 2 and hypoplastron 4 simultaneously on the wedge subassembly through forked tail cooperation structure 8, make the relative position of upper plate 2 and hypoplastron 4 more stable to further guarantee the stability of motor position. In addition, the stability of the motor is ensured, so that the adjustment process of the belt tension can be carried out under the running state of the pumping unit, and the adverse effect of the shutdown of the pumping unit on the production is avoided. The dovetail matching structure 8 not only plays a role in connection, but also can provide a sliding matching pair, and is a common precision transmission mechanism on a machine tool, and details are not repeated here, so that for convenience of understanding, please refer to fig. 3.
As a further technical solution, as shown in fig. 1, one end of the upper arm 12 corresponding to the nut B18 is in sliding fit with the lower side of the upper housing 10 through a dovetail fit structure 8, and the upper housing 10 is provided with a relief groove 11 for the dovetail fit structure 8 to disengage; correspondingly, the hinge shaft between the upper support arm 12 and the upper shell 10 is installed in a strip-shaped hole 13, so that the upper support arm 12 and the upper shell 10 can slide relatively; when the nut B18 slides away from the nut A17, the binding action of the dovetail matching structure 8 on the upper support arm 12 is released, so that the upper shell 10 and the upper support arm 12 can rotate relatively; the coupling structure between the lower arm 15 and the lower case 16 is identical to the coupling structure between the upper arm 12 and the upper case 10. The detachable dovetail matching structure 8 is arranged on the outer sides of the upper support arm 12 and the lower support arm 15 and the inner sides of the upper shell 10 and the lower shell 16, and when the tension of a belt is adjusted (namely the upper support arm 12 and the lower support arm 15 are not supported), the dovetail matching structure 8 at the position can be used as a supporting point at the middle part of the upper shell 10 to improve the supporting stability of the lower side of the upper shell 10 and simultaneously prevent the upper support arm 12 and the lower support arm 15 from being overturned when the belt is replaced.
In specific implementation, a locking device which is locked in a normal state can be arranged between the upper shell 10 and the lower shell 16, and the locking is kept when the tension is adjusted, so that the position stability between the upper shell 10 and the lower shell 16 is improved, and the locking device can be unlocked when the upper support arm and the lower support arm are supported.
Example two:
as shown in fig. 4 and 5, the present embodiment is different from the first embodiment in that a strip-shaped hole 13 is added to a nut B18, and a ratchet 19 is added at the junction of the upper case 10 and the lower case 16.
The above modification makes the upper casing 10 hooked on the lower casing 16 by the ratchet 19 before the upper and lower arms are erected, which is advantageous for securing the positional stability between the upper and lower plates 2 and 4, and the upper and lower arms are erected at the initial stage, the upper and lower casings 10 and 16 are dislocated so that they can be separated to erect the upper and lower arms. It should be noted that, in order to shift the upper casing 10 and the lower casing 16, the length of the strip-shaped hole 13 on the lower casing 16 must be larger than the length of the strip-shaped hole 13 on the upper casing 10.
After improvement, the upper support arm and the lower support arm are sequentially supported instead of being simultaneously supported.
