Description

Technical Field

[0001] The utility model relates to the technical field of tower pumping units, in particular to a well repairing and giving way mechanism for a tower pumping unit. Background Art

[0002] The tower pumping unit eliminates the walking beam and only has a tower and a platform. It uses belts and belt rollers, or chains and wire ropes to convert the circular motion of the reversible motor into the up and down linear motion of the sucker rod. This type of tower pumping unit usually installs the reversible motor and reducer on the platform at the top of the tower. Later, it evolved to install the reversible motor and reducer on the well platform below the tower.

[0003] Tower pumping units have many advantages over beam pumping units, but they also have disadvantages. The distance between the well platform and the derrick and the oil wellhead is relatively close, or less than the 0.7-meter distance required by the technical specifications, which brings inconvenience to oil well maintenance. When repairing a well, the derrick must generally be moved as a whole to give the repair machine a distance for installation. Moving the tall and bulky derrick is time-consuming, which directly affects the oil production of a single well. At the same time, there are also major safety hazards. Utility Model Content

As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof. "Well", "oil well", etc. mentioned herein are all abbreviations for "oil production well".

[0022] Unless otherwise specifically stated, the relative arrangement of the parts and steps described in these embodiments, the numerical expressions and numerical values ​​do not limit the scope of the utility model. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The techniques, methods and equipment known to ordinary technicians in the relevant fields may not be discussed in detail, but in appropriate cases, the techniques, methods and equipment should be regarded as part of the authorization specification. In the given examples shown and discussed here, any specific values ​​should be interpreted as merely exemplary and not as a limitation. Therefore, other examples of exemplary embodiments may have different values, such as the length of the groove 4.

[0023] In the description of the present utility model, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the outline of the components themselves in the figure, such as the outer frame 5 and the inner frame 11 are only in terms of their relative positions in the figure.

The shape is as follows Figure 6 It is the best, other types of bolts are also possible. One of their functions is to assist in limiting the position of the mobile base 3. The left and right moving distance in the direction shown in the figure is limited by the length of the groove 4 and generally does not exceed one meter. This is the clearance distance during well repair, and the horizontal space for installing the well repair machine can be used. Another function is to tighten the limiting bolt assembly 9 after determining the distance to fix the mobile base 3 and the box-type derrick 16.

[0027] The mobile base 3 includes two inner frames 11 and two outer frames 5 on both sides of the groove 4, and five cross frames 12. The gap between the inner frame 11 and the outer frame 5 forms the groove 4. The reserved groove 4 has a length of one meter, and the rest is welded flat with a reinforcing plate 15, and the inner frame 11 and the outer frame 5 are connected together. Figure 1, Figure 4 As shown, a set of cross frames 12 are connected between the inner frames 11, and the right rear section of the inner frame 11 and the outer frame 5 are connected by two sets of derrick hinge shafts 10, and a box-type derrick 16 is installed on it. The mobile base 3 is controlled by the oil cylinder 14 to move inside the right-angle slide rail 2 of the mobile well platform 1. The telescopic end of the oil cylinder 14 is connected to the mobile base 3 through the hinge shaft, and the oil cylinder seat 8, oil pump 7 and solenoid valve 6 of the oil cylinder 14 are fixed to the mobile well platform 1 by bolts. When repairing the well, move 70-100CM to the left in the direction shown in the figure, and move right to reset after repairing the well to restore to the oil production state.

[0028] The inner frame 11 and the right rear section of the outer frame 5 are connected by a derrick hinge shaft 10. Figure 4 , Figure 5 As shown, the derrick hinge shaft 10 is used for connection so that when the box-type derrick 16 is transported, it can be turned over and laid flat to lower the height for easy loading and transportation. The right rear section of the inner frame 11 and the outer frame 5 is also fixed to the mobile well platform 1 by the limit bolt assembly 9; the limit bolt assembly 9 can be removed and folded and turned 90 degrees in the counterclockwise direction through the hinge shaft 10. The limit bolt assembly 9 includes a columnar body with internal threads, a flat head bolt with external threads, and a square gasket, wherein the columnar body with internal threads is welded to the corresponding position on the inner side of the right-angle slide rail 2 corresponding to the six grooves 4. As mentioned above, it is not limited to this type of bolt, and other types of bolts can also be used.
