[0002] In the middle and late stages of oilfield development, most of the oil production equipment used are beam pumps for mechanical oil production. During the long-term operation of the equipment, due to the alternating changes in downhole loads, the pumping unit's unloading, loading, installation, pump collision, adjustment of anti-impact distance and other operations, the fasteners at the connection parts of the pumping unit equipment are subjected to alternating stress changes, and the equipment's connecting fasteners such as bolts are subjected to fatigue stress. The bolts become loose or broken, causing relative displacement between two parts of the equipment. If these loose parts are not discovered in time, major mechanical accidents such as pumping unit overturning may occur, and serious accidents may result in casualties.

[0003] In the actual operation of the equipment, during the inspection process, since the inspection personnel standing on the ground have a low observation position, it is difficult to quickly see the changes in the various connections of the higher walking beam of the oil pump, and the problem cannot be found in a short time. When the connecting firmware is slightly loose, it is difficult to observe at a long distance on the ground. The oil pump equipment can only be stopped and then inspected. During the shutdown inspection, the loose parts will be in a static state as the oil pump stops running, and it is difficult for observers to find the problem. In addition, since the looseness of the connecting firmware cannot be observed, if the oil pump is operated in this state, the beam or connecting rod will fall, causing major safety accidents such as object impact and personal injury to the operator. Summary of the invention

[0023] Example 1

[0024] like Figure 2-3 As shown, the telescopic mechanism includes a sleeve 3, one end of the two sleeves 3 is fixedly connected to the upper foot seat 21 and the lower foot seat 22 respectively, the other end of the sleeve 3 is connected to a threaded rod 51 through a thread, the end of the threaded rod 51 away from the sleeve 3 is connected to a connecting block 52, the two connecting blocks 52 are each provided with a connecting hole 53, and a display device is connected between the two connecting holes 53. The two sleeves 3 are welded to the upper foot seat 21 and the lower foot seat 22.

[0025] The two opposite sides of the outer wall of the end of the sleeve 3 close to the threaded rod 51 are set as planes, and the plane size is 25mm×12mm. The setting of the plane is used to play a role in fixing the spare pliers when tightening the spare cap 4.

[0026] The sleeve 3 is a hollow round tube with a diameter of 25 mm and a length of 70 mm. The inner wall of the sleeve 3 is provided with an internal thread, which matches the threaded rod 51. When the bonding position of the upper foot seat 21 or the lower foot seat 22 changes, the limited threshold amount of screwing in or out of the threaded rod 51 into or out of the sleeve 3 is 25 mm, so that the threaded rod 51 can reach a matching state with the position of the glass tube seat 9, so that the glass tube 6 can be vertically installed in the upper threaded rod 51 and the glass tube seat 9 with a high concentricity without generating torque, as shown in FIG. Figure 4 shown.

[0027] Example 2

[0028] The display device includes a glass tube 6, one end of which is connected to a glass tube holder 9, the glass tube 6 and the glass tube holder 9 respectively pass through two connection holes 53, the surfaces of the glass tube 6 and the glass tube holder 9 are wrapped with developing cloth 8, and the glass tube 6 is filled with developing solution 7. A sealed wooden plug is connected to the top of the glass tube 6 to block the developing solution 7, the glass tube 6 passes through the connection hole 53 and is fixed by white porcelain glue, the developing solution 7 is a fluorescent developing solution, a certain amount of antifreeze is added therein to ensure that it does not freeze in a low temperature environment, when the connecting part of the device is displaced, the torque generated causes the glass tube 6 to break, the developing solution 7 in the glass tube 6 flows out and adheres to the developing cloth 8, which can be observed from a distance and plays a warning role, the developing cloth 8 can also wrap the broken glass tube 6 to prevent the glass fragments from being scattered, and at the same time can buffer the vibration of some smaller pumping units to prevent the glass tube 6 from breaking under the displacement of non-device firmware.

[0029] Example 3

[0030] The glass tube holder 9 includes a connecting rod 91, which passes through the connecting hole 53. One end of the connecting rod 91 is connected to a placing platform 92, which is arranged between the two connecting holes 53. A groove 93 is provided at the end of the placing platform 92 away from the connecting rod 91. The glass tube 6 is arranged in the groove 93. The side wall of the placing platform 92 is evenly provided with a plurality of guide grooves 94 along its length direction. The developing cloth 8 is wrapped around the outer surface of the connecting rod 91 and the placing platform 92. The bottom end of the glass tube 6 is arranged in the groove 93 and fixed by white porcelain glue. The placing platform 92 is a truncated cone structure. The groove 93 is provided on the smaller end face of the placing platform 92. The connecting rod 91 is an M12 external thread screw with a length of 65 mm. The connecting rod 91 is threadedly connected to the connecting hole 53 below. The height of the placing platform 92 can be adjusted by rotating the connecting rod 91 to match the positions of the two connecting pieces on the oil production equipment. The setting of the guide groove 94 facilitates the developer 7 to flow along the guide groove 94 onto the developing cloth 8 after the glass tube 6 is broken.

[0031] Example 4

[0032] Both ends of the upper foot 21 and the lower foot 22 are inclined, and the inclination angles of both ends of the upper foot 21 and the lower foot 22 are set to 15°. The size of the upper foot 21 and the lower foot 22 is 28mm×100mm, and a number of through holes are evenly opened in the middle of the upper foot 21 and the lower foot 22. The upper foot 21 and the lower foot 22 are inclined at both ends for easy disassembly. The upper foot 21 and the lower foot 22 are thin sheets with a thickness of 5mm, and the diameter of the through hole is 5mm, which is convenient for the metal adhesive to more firmly bond the upper foot 21 and the lower foot 22 to the oil production equipment.

[0033] The present invention is used for an early warning device for loosening of oil production equipment firmware, and its working principle is as follows:

[0034] The upper foot seat 21 and the lower angle seat 22 are respectively adhered to the walking beam tail plate 11 and the tail bearing upper seat 12 by metal adhesive, and the connecting rod 91 is rotated and adjusted according to the specific position to adjust the height of the placement table 2, that is, to determine the position of the glass tube 6, and notify the glass tube 6 and the glass tube seat 9 to be wrapped with a developing cloth. When the firmware of the oil production equipment is loose, the torque generated by the displacement of the loose walking beam tail plate 11 and the tail bearing upper seat 12 breaks the glass tube 6, and the developer 7 in the glass tube 6 flows along the guide groove 94 onto the developing cloth, so that the staff can observe from a distance and tighten or repair the components in time, which has never played a warning role.

[0035] The present invention is used for the early warning device of loosened firmware of oil production equipment. When the firmware connecting the oil pumping unit equipment is loosened, the walking beam and the tail bearing seat are displaced, resulting in the breaking of the glass tube, the developer in the tube flowing out and being absorbed by the developing cloth, and the color of the developing cloth also changing. When the inspection personnel conduct inspection, the color change of the developing cloth can be clearly observed on the ground, and the next step of measures can be taken in time to eliminate the hidden danger in the bud.
