Description

Technical Field

[0001] The utility model relates to the technical field of pumping unit accessories, in particular to a rope hanger that does not stop production when a rod breaks. Background Art

[0002] The rope hanger is a connecting device between the donkey head and the sucker rod of the oil pumping well. Specifically, the upper part of the rope hanger is connected to the donkey head with a hanging rope, and the lower part is connected to the sucker rod with a square clip. At present, a slot for inserting a polished rod is provided on the rope hanger body. The polished rod can be placed into the slot from one side of the middle part of the rope hanger body. When the polished rod is in the slot, a baffle is used to block the slot, and then two bolts are used to fix the baffle to the rope hanger body. This can achieve the purpose of fixing the polished rod in the rope hanger, as shown in the attached figure. Figure 7 As shown in point B, during use, the light rod is prone to vibration or even deflection due to the force applied, and the stress at the contact point between the light rod and the rope hanger is relatively concentrated, which can easily cause the light rod to break. In the existing technology, most rope hangers do not have the function of not stopping production when the rod breaks. Once the light rod breaks, the oil well will be shut down, and oil leakage will occur, causing pollution problems. Later improvements added anti-rod breakage devices, but they were all installed later and were not a whole with the original rope hanger, which seriously affected the integrity of the appearance. It is also very inconvenient to disassemble and maintain it. In view of this, in-depth research was conducted on the above-mentioned problems, and this case was created. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process.

[0025] Example: In conjunction with the instructions attached Figure 1-7It can be seen that this scheme specifically designs a rope hanger that does not stop production even when the rod is broken, including a fixing seat 1 and a pair of T-shaped side plates 2 with the same structure. The pair of T-shaped side plates 2 are symmetrically assembled and fixed by bolt fasteners. The fixing seat 1 is assembled and connected to the upper end of the T-shaped side plate 2; the above-mentioned T-shaped side plate 2 is a T-shaped metal plate, and a rectangular through groove 201 is opened in the middle of the T-shaped metal plate. The upper end cross beam position of the T-shaped metal plate is opened in the vertical direction with an upper through semicircular hole 202, and the lower end cross beam position is opened with a lower through semicircular hole 2 03, a stepped through hole 204 is provided on one side of the upper semicircular hole 202 in the horizontal direction, a positioning ring 3 is installed in the stepped through hole 204, and a positioning blind hole 205 is provided on the top surface of the T-shaped metal plate; wherein the fixing seat 1 is a rectangular metal plate, a top through hole 101 is provided at the center of the rectangular metal plate, a positioning hole 102 is provided on the rectangular metal plate, a positioning pin 4 is embedded in the positioning hole 102, and the lower end of the positioning pin 4 is inserted into the positioning blind hole 205; the upper semicircular hole 202 is connected to the docking assembly The upper through hole, the lower through hole 203 and the top through hole 101 formed by connecting the upper through hole and the lower through hole 203 are inserted into the position of the polished rod 5, and the upper clamp 6 and the lower clamp 7 are installed on the polished rod 5. The upper clamp 6 is located at the upper part of the T-shaped metal plate, and the lower clamp 7 is located at the rectangular through hole in the middle of the T-shaped metal plate. The diameter of the upper through hole is smaller than the diameter of the lower through hole. The combined design of the fixing seat 1 and a pair of T-shaped side plates 2 with the same structure is adopted. The assembly and fixation are carried out by bolt fasteners and positioning pins 4, which has better integrity, high overall strength, and is easy to disassemble and maintain. At the same time, the cooperation of the upper clamp 6 and the lower clamp 7 realizes double clamping and locking of the polished rod 5 in the vertical direction. During use, after the upper part of the polished rod 5 is overloaded and broken, the upper clamp 6 fails. At this time, the lower clamp 7 can cooperate with the rope hanger to fix the polished rod 5, which has a broken rod protection function. That is, once the polished rod 5 breaks, the oil well can continue to operate, avoiding the shutdown of the oil well and the problem of oil leakage pollution.

[0026] In the specific implementation process, as a preferred setting, the above-mentioned bolt fastener includes a locking nut 8 and a locking bolt 9. One end of the locking nut 8 passes through the stepped through hole 204 and is inserted into the positioning ring 3. The locking bolt 9 is inserted through the joint through hole on the other side and is threadedly matched with the locking nut 8. It has a simple structure, is easy to assemble, has good stability and high strength.

[0027] During the specific implementation process, as a preferred setting, the diameter of the above-mentioned upper through hole is 35 mm, and the diameter of the lower through hole is 38 mm. The upper through hole cooperates with the upper chuck 6 to clamp and fix the upper part of the light rod 5. The lower chuck 7 is located above the lower through hole. The diameter of the lower through hole is slightly larger than the diameter of the upper through hole, which allows the light rod 5 to have a certain swing space at the position of the lower through hole. In this way, the stress points on the light rod 5 are concentrated on the upper chuck 6 and the upper crossbeam position of the rope hanger. Once a break occurs, the lower chuck 7 can cooperate with the rope hanger to keep the light rod 5 in the current position without falling, thereby ensuring the continuity of the oil pumping operation.

[0028] During the specific implementation process, as a preferred setting, the above-mentioned T-shaped metal plate is symmetrically provided with stepped semicircular grooves 206 on both sides, and the stepped circular grooves formed by the stepped semicircular grooves 206 are provided with a steel wire rope 10, and a rope loop 11 is fixedly installed at the lower end of the steel wire rope 10. Arc-shaped notches 103 are symmetrically provided on both sides of the rectangular metal plate, and the arc-shaped notches 103 match the stepped semicircular grooves 206, which is convenient for limiting and fixing the steel wire rope 10. The structure is simple and safe and reliable.

[0029] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
