Detailed Description
The invention is further described in connection with the following detailed description, in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the invention easy to understand.
As shown in fig. 1 to 5, the device comprises a polish rod, a hanging bracket and a motor, wherein the polish rod is connected with an output shaft of the motor, and the hanging bracket is connected on the polish rod in a sliding manner;
The hanging bracket comprises a vertical rod, an upper hook, an eccentric part and a bent rod, wherein the upper hook is fixedly connected to the upper end of the vertical rod, the eccentric part is fixedly connected to the inner side of the upper hook, and the bent rod is fixedly connected to the lower end of the vertical rod;
A first eccentricity e1 exists between the position of the contact point of the eccentric part and the polish rod and the position of the central point of the upper hook, and a second eccentricity e2 exists between the position of the central point of the upper hook and the position of the central point of the bent rod.
Fig. 3 shows the hanger hook in a close-up manner, the eccentric part 103 below the upper hook 102 is biased to the left side of the hanger, when the hanger 2 is hung on the polish rod 1, the eccentric part 103 contacts with the polish rod 1, and in order to keep balance, the hanger 2 is also designed into an eccentric structure, as shown in fig. 2.
Fig. 4 shows a schematic diagram of the eccentricity of the upper hook 102, the eccentric member 103, and the hanger vertical rod 101 of the hanger 2, wherein a first eccentricity e1 is formed between the position of the contact point between the eccentric member 103 and the polish rod 1 and the position of the central point of the upper hook 102, and a second eccentricity e2 is formed between the position of the central point of the upper hook 102 and the position of the central point of the bent rod 104, and the hanger 2 tilts under the action of gravity when the polish rod 1 rotates due to the eccentricities e1 and e 2.
Because the upper hook 102 of the hanger 2 has the eccentric distance e1, when the polish rod 1 rotates, the single side contacted by the eccentric part 103 on the polish rod 1 receives friction force to push the upper hook 102 to deflect as shown in fig. 5, so that the friction force exerted on the eccentric part 103 by the polish rod 1 generates axial component force to push the hanger 2 to axially move along the polish rod 1, and the purpose of logistics conveying is realized.
Specific embodiments and principles:
By setting, a first eccentric distance e1 between the contact point position of the eccentric member 103 and the polished rod 1 and the central point position of the upper hook 102 is larger than the diameter of the upper hook 102 and smaller than twice the diameter of the upper hook 102, and a second eccentric distance e2 between the central point position of the upper hook 102 and the central point position of the bent rod 104 is set to be 3-5 times the first eccentric distance e1.
Due to the eccentricity e1, e2, the hanger 2 tilts under the force of gravity as the polish rod 1 rotates.
Therefore, when the polish rod 1 rotates, the single side contacted by the eccentric part 103 on the polish rod 1 receives friction force to push the upper hook 102 to deflect, as shown in fig. 5, so that the friction force exerted on the eccentric part 103 by the polish rod 1 generates axial component force to push the hanger 2 to axially move along the polish rod 1, and the purpose of logistics conveying is realized.
Based on the above, the invention is driven by sliding friction force, the mechanical structure is simple, the hanger rail is convenient to change, the cost is low, the hanger only slides on the polish rod, the mechanical failure is not easy to generate, and the safety is high.
It will be appreciated by those skilled in the art that the present invention can be carried out in other embodiments without departing from the spirit or essential characteristics thereof. Accordingly, the above disclosed embodiments are illustrative in all respects, and not exclusive. All changes that come within the scope of the invention or equivalents thereto are intended to be embraced therein.
