The weight of the counterweight 4 substantially balances the weight of the load on the side of the sucker rod, and the motor 20 drives the drive rope through the power unit. 11 and the tether rope 6 are moved, so that only a small amount of electric power is required to rotate the beam 9 about the support shaft 10. Preferably, as shown, the position of the lanyard on the hoes 32, 33 is symmetrically disposed at the center of rotation of the beam 9.
所述电控装置 23与电动机连接, 所述电动机 20的输出轴与动力装置 连接。 本发明中的电控装置采用电控拒 23形式, 通常在电控拒 23中设置 有变频器、 可编程序控制器(PLC )、 制动单元、 显示单元等电器件。 变 频器的输出端与电动机 20相连,在变频器的控制下电动机 20有规律地正 转、 反转, 从而实现游梁 9绕支承轴 10的转动和抽油杆的上、 下往复运 动。  The electronic control unit 23 is coupled to an electric motor, and an output shaft of the electric motor 20 is coupled to the power unit. The electronic control device of the present invention adopts the form of electronic control rejection 23, and is usually provided with an inverter, a programmable controller (PLC), a brake unit, a display unit and the like in the electronic control rejection 23. The output of the frequency converter is connected to the motor 20, and the motor 20 is regularly rotated and reversed under the control of the frequency converter, thereby realizing the rotation of the beam 9 around the support shaft 10 and the upward and downward reciprocating movement of the sucker rod.
但在本实施方式中没有齿轮变速箱, 而是采用无齿传动的天平式游梁 抽油机。 采用无齿传动方式, 运行时只需选用小功率电机, 因此节电效率 高, 比一般游梁式抽油机相比节电 40%-70%。而且单纯的皮带传动没有噪 音、 也没有漏油现象, 能够克服采用变速箱的抽油机运行噪音大、 漏油情 况严重的缺陷。 在本实施方式中, 由于需要电动机的扭矩大、 转速低, 因 此通常采用永磁同步电机。  However, in the present embodiment, there is no gear transmission, but a balance-type beam pumping unit using a toothless transmission. Adopting the gearless transmission mode, only a small power motor is used during operation, so the power saving efficiency is high, and the power saving is 40%-70% compared with the general beam pumping unit. Moreover, the simple belt drive has no noise and no oil leakage, and can overcome the defects of large running noise and serious oil leakage of the pumping unit using the transmission. In the present embodiment, since the torque of the motor is required to be large and the number of revolutions is low, a permanent magnet synchronous motor is usually employed.
具体地, 所述动力装置包括第一皮带轮 21、 第二皮带轮 18和皮带 19 , 其中, 第一皮带轮 21 安装在所述电动机的输出轴上, 第二皮带轮 18安装在所述驱动轮轴上, 所述皮带 19连接所述第一皮带轮和第二皮 带轮, 所述电动机的输出转矩大于或等于 G, G通过下式定义:  Specifically, the power unit includes a first pulley 21, a second pulley 18, and a belt 19, wherein the first pulley 21 is mounted on an output shaft of the motor, and the second pulley 18 is mounted on the drive axle. The belt 19 connects the first pulley and the second pulley, and the output torque of the motor is greater than or equal to G, G is defined by:
G=PxD/ ( 2χΚ ), 其中, Ρ为电动机输出的牵引力, D为驱动轮直径, K为第二皮带轮 18直径与第一皮带轮直径之比, Ρ为 3000Ν至 50000Ν。 实施例 3 G=PxD/ ( 2χΚ ), where Ρ is the traction of the motor output and D is the diameter of the drive wheel. K is the ratio of the diameter of the second pulley 18 to the diameter of the first pulley, and Ρ is 3000 Ν to 50,000 。. Example 3
图 5是利用驱动轮和驱动绳牵引游梁的天平式游梁抽油机的结构示意 图; 图 6是图 5所示的天平式游梁抽油机结构的俯视图。  Fig. 5 is a schematic structural view of a balance beam pumping unit for pulling a beam by means of a driving wheel and a driving rope; Fig. 6 is a plan view showing the structure of the balance beam pumping unit shown in Fig. 5.
所述天平式游梁抽油机包括游梁 9、 支承架 8、 挂绳机构、 动力装置、 驱动绳 11、 驱动轮 3、 配重 4、 抽油杆 15、 电控装置 23、 电动机 20。 其 中, 挂绳机构包括驴头 31、 32、 33以及驴头绳 6、 挂绳器 13。 所述游梁 9 通过支承轴 10安装在所述支承架 8上, 所述支承架 8安装在所述抽油机 的机架 30上, 所述抽油杆 15和所述配重 4分别位于游梁 9的两端并且均 通过挂绳机构分别与游梁 9的两端连接。 配重 4设置在游梁 9上与抽油杆 15相对的一侧,配重 4的重量基本平衡了抽油杆一侧负载的重量。但抽油 杆一侧的重量略大于配重一侧的重量, 因此, 抽油杆可以依靠自身重量下 降, 也可以在电动机 20的牵引下提升。 电动机 20通过动力装置带动驴头 绳 6运动, 因此只需要很小的电能就能使游梁 9绕支承轴 10旋转。  The balance beam pumping unit comprises a beam 9, a support frame 8, a lanyard mechanism, a power unit, a drive rope 11, a drive wheel 3, a counterweight 4, a sucker rod 15, an electric control unit 23, and an electric motor 20. Among them, the lanyard mechanism includes a hoe 31, 32, 33 and a sling rope 6, and a lanyard 13. The beam 9 is mounted on the support frame 8 via a support shaft 10, the support frame 8 is mounted on the frame 30 of the pumping unit, and the sucker rod 15 and the counterweight 4 are respectively located Both ends of the beam 9 are connected to both ends of the beam 9 by a lanyard mechanism. The counterweight 4 is disposed on the side of the beam 9 opposite the sucker rod 15, and the weight of the counterweight 4 substantially balances the weight of the load on the side of the sucker rod. However, the weight on the side of the sucker rod is slightly larger than the weight on the side of the weight. Therefore, the sucker rod can be lowered by its own weight or lifted under the traction of the motor 20. The motor 20 drives the hammer rope 6 through the power unit, so that only a small amount of electric power is required to rotate the beam 9 about the support shaft 10.
在本实施方式中, 也可采用变速箱的传动方式, 即动力装置包括第一 皮带轮 21、 第二皮带轮 18、 皮带 19和变速箱 17。 电动机 20的输出轴上 安装有第一皮带轮 21 , 通过皮带 19, 将扭矩传输到第二皮带轮 18, 第二 皮带轮 18连接变速箱, 所述变速箱为齿轮箱, 具有多组相互啮合的齿轮, 变速箱的输出轴连接驱动轮 3。  In the present embodiment, the transmission mode of the transmission can also be employed, i.e., the power unit includes the first pulley 21, the second pulley 18, the belt 19, and the transmission 17. A first pulley 21 is mounted on the output shaft of the motor 20, and the torque is transmitted to the second pulley 18 through the belt 19, and the second pulley 18 is connected to the gearbox. The gearbox is a gearbox having a plurality of sets of mutually meshing gears. The output shaft of the gearbox is connected to the drive wheel 3.
与上述抽油机不同的是: 在本实施方式中驱动绳 11 的一端与游梁 9 的挂绳机构 33相连, 而另一端与驱动轮 3的轮周连接, 该抽油机不设置 涨紧轮 5和导向轮 12及一个挂绳机构, 因此, 结构比较简单、 安装方便。  Different from the above pumping unit: In the present embodiment, one end of the driving rope 11 is connected to the lanyard mechanism 33 of the beam 9 and the other end is connected to the wheel circumference of the driving wheel 3, and the pumping unit is not set to tighten. The wheel 5 and the guide wheel 12 and a lanyard mechanism are therefore relatively simple in structure and convenient to install.
实施例 4  Example 4
图 7是动力装置只包括电动机、 皮带轮、 皮带, 并且利用驱动轮和驱 动绳牵引游梁的天平式游梁抽油机的结构示意图, 图 8是图 7所示的天平 式游梁抽油机结构的俯视图。  7 is a schematic structural view of a balance type beam pumping unit in which the power unit includes only an electric motor, a pulley, a belt, and the traveling beam is driven by the driving wheel and the driving rope, and FIG. 8 is a balance type beam pumping unit shown in FIG. Top view of the structure.
如图所示, 与图 5、 图 6所示的实施方式相似, 驱动绳 11的一端与挂 绳机构相连, 而另一端与驱动轮 3的轮周连接。 但更优选地, 本实施方式 中的抽油机还采用了如图 3、 图 4所示的无齿动力装置, 因此这种机型是 结构最简单, 但需要大扭矩、 低转速电动机, 通常采用永磁同步电动机。 实施例 5 As shown, similar to the embodiment shown in Figs. 5 and 6, the drive cord 11 has one end connected to the lanyard mechanism and the other end connected to the wheel circumference of the drive wheel 3. More preferably, however, the pumping unit in the present embodiment also employs a toothless power unit as shown in FIGS. 3 and 4, so the model is The structure is the simplest, but requires a high torque, low speed motor, usually with a permanent magnet synchronous motor. Example 5
图 9是动力装置只包括电动机、 链轮、 链条时天平式游梁抽油机的结 构示意图; 图 10是图 9所示的天平式游梁抽油机结构的俯视图。  Fig. 9 is a schematic view showing the structure of a balance beam pumping unit when the power unit includes only an electric motor, a sprocket, and a chain; and Fig. 10 is a plan view showing the structure of the balance beam pumping unit shown in Fig. 9.
在该实施例中, 驱动绳 11绕过驱动轮 3、 涨紧轮 5和导向轮 12, 并 且驱动绳 11的两端分别与安装在游梁两端上的挂绳机构连接。 具体地, 驱动绳 11分别绕过驱动轮 3、 涨紧轮 5和导向轮 12。 如图所示, 驱动 轮 3、 涨紧轮 5和导向轮 12安装在所述抽油机的机架 30上, 涨紧轮 5 紧靠在驱动绳 11上,以使驱动绳 11张紧,从而使传动机构高效地传动。 优选地, 涨紧轮 5的轴与调紧装置 22相连, 以便调节驱动绳 11的松紧 程度和驱动轮 3上的驱动绳 11的包角大小。调紧装置 22采用调整螺杆, 可改变涨紧轮 5的轮轴位置。  In this embodiment, the drive rope 11 bypasses the drive wheel 3, the tension pulley 5 and the guide wheel 12, and both ends of the drive rope 11 are respectively coupled to the lanyard mechanisms mounted on both ends of the beam. Specifically, the drive ropes 11 bypass the drive wheels 3, the tension pulleys 5, and the guide wheels 12, respectively. As shown, the drive wheel 3, the tensioning pulley 5 and the guide wheel 12 are mounted on the frame 30 of the pumping unit, and the tensioning pulley 5 abuts against the drive rope 11 to tension the drive rope 11 Thereby the transmission mechanism is driven efficiently. Preferably, the shaft of the tensioning pulley 5 is coupled to the tightening device 22 to adjust the degree of tightness of the drive cable 11 and the wrap angle of the drive cable 11 on the drive wheel 3. The adjusting device 22 uses an adjusting screw to change the position of the axle of the tensioning pulley 5.
但与之前的实施方式不同的是: 本实施方式用链轮链条方式代替皮 带传动方式。 具体地, 所述动力装置包括第一链轮 26、 第二链轮 24和 链条 25。 其中, 电机 20的输出轴上同轴安装有第一链轮 26, 第一链轮 26的直径较小。抽油机的驱动轮轴通过轴承安装在机架上, 在驱动轮轴 上同轴安装有第二链轮 24和驱动轮 3, 第二链轮 24具有比第一链轮 26 更大的直径。 第一链轮 26和第二链轮 24通过链条 25相连。 由于第二 链轮 24固定在驱动轮轴上(例如通过过盈配合或键联接) , 链条 25可 以将电机 20的输出转矩和转速传递到驱动轮轴。  However, unlike the previous embodiment, this embodiment uses a sprocket chain method instead of the belt transmission. Specifically, the power unit includes a first sprocket 26, a second sprocket 24, and a chain 25. The first sprocket 26 is coaxially mounted on the output shaft of the motor 20, and the diameter of the first sprocket 26 is small. The drive axle of the pumping unit is mounted to the frame by bearings, and a second sprocket 24 and a drive wheel 3 are coaxially mounted on the drive axle, the second sprocket 24 having a larger diameter than the first sprocket 26. The first sprocket 26 and the second sprocket 24 are connected by a chain 25. Since the second sprocket 24 is fixed to the drive axle (e.g., by an interference fit or a keyed coupling), the chain 25 can transmit the output torque and rotational speed of the motor 20 to the drive axle.
在本实施例中, 优选地, 电机 20采用 7ja兹同步电机, 更优选地选用 输出转矩 300Nm以上、 输出功率 5-45Kw、 转速在 500rpm以下的 7j 兹同 步电机。在本实施例中,采用额定输出转矩 1200Nm、额定输出功率 10.7kw, 额定转速 85rpm的 兹同步电机。这是因为, 兹同步电机更能满足大转 矩、 低转速的工作要求, 不仅有利于节约能源, 更能避免高转速电机工作 时产生的噪音, 进一步降低了抽油机整体的工作噪音。 Embodiment, preferably, the motor 20 using 7 ja hereby synchronous machine in the present embodiment, more preferably selected output torque 300Nm above, the output power 5-45Kw, the rotational speed of the synchronous machine 7 j hereby 500rpm or less. In the present embodiment, a zigzag motor having a rated output torque of 1200 Nm, a rated output of 10.7 kW, and a rated speed of 85 rpm is used. This is because the synchronous motor can meet the requirements of high torque and low speed, which not only helps to save energy, but also avoids the noise generated when the high speed motor works, and further reduces the overall working noise of the pumping unit.
该抽油机中的链条传动结构具有传动扭矩较大的特点, 因此需要牵引 力较大的大型抽油机可采用这种抽油机。  The chain transmission structure of the pumping unit has the characteristics of large transmission torque, so that a large pumping unit that requires a large traction force can adopt such a pumping unit.
尽管本发明是通过上述的优选实施例进行描述的,但是其实现形 式并不局限于上述的实施方式。 应该认识到在不脱离本发明主旨的情况 下, 本领域技术人员可以对本发明做出不同的变化和修改。 Although the invention has been described in terms of the preferred embodiments described above, The formula is not limited to the above embodiment. It will be appreciated that various changes and modifications of the invention may be made by those skilled in the art without departing from the scope of the invention.
