Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without any creative work belong to the protection scope of the present invention.

Example (b): referring to fig. 1-4, the belt reciprocating type oil pumping and well repairing integrated machine comprises a platform guardrail 21, an operating platform 20 and a derrick 22, which are not different from the prior art and are characterized in that: the belt roller 11 connected with the fixed driving mechanism 10 is installed on the operating platform 20 on the upper part of the derrick 22, the clutch state of the belt shaft 110 of the belt roller 11 and the output shaft 107 is regulated and controlled by the left fluted disc 108 and the right fluted disc 109, that is, a set of clutch mechanism is additionally arranged between the belt roller 11 and the belt shaft 110 and the output shaft 107 of the fixed driving mechanism 10, so that the belt roller 11 can be separated from the output shaft 107 and auxiliary equipment can be operated independently when necessary, and can rotate freely in the forward and reverse directions, and can be simply used as a pulley.

Thus, during workover, the wire rope and the well pipe hoisting belt 41 are pulled by the wire rope roller 42 connected to the traveling drive mechanism 40 mounted on the base 43 below the derrick 22, and the well pipe is hoisted to the ground through the belt roller 11. The movable driving mechanism 40 is movably connected with the base 43, and can be detached and installed on the base 43 under other derricks when necessary, and is also used for workover operation. The wire rope of the wire rope roll 42 of the mobile drive 40 is connected to the well pipe hoisting belt 41 (the belt 31 can also be shared) through the belt clamp 32, when the well pipe is hoisted, the power of the motor of the mobile drive 40 is generally twice that of the motor of the fixed drive 10, and the motor is matched according to the well depth parameters of each well, and is generally selected to be 40 kilowatts.

Compared with the prior art, the oil pumping unit and the workover rig can be used independently, but the utility model only adds one clutch, namely: the output shaft 107 is connected to a clutch moving disk 105 via a coupling 106, the clutch moving disk 105 is engaged by a return spring 104, the clutch moving disk 105 is disengaged by an electromagnet housing 102 with a built-in coil assembly 103, and few conventional fittings are necessary.

The effective height of the derrick 22 can reach 12 m, and the length of a single well pipe is about 9 m, namely, the space for lifting the well pipe is enough.

The mode of operation is such that when workover is required, the fixed drive 10 motor is stopped, the belt clamp 32 is removed, and the well pipe elevator is connected; 36V direct current is introduced into a coil group 103 of the electromagnet shell 102, a clutch moving part 105 is attracted and moves to the left, a left fluted disc 108 is separated from a right fluted disc 109, and the belt roller 11 and the belt shaft 110 are in a free rotation state; after the belt 30 and the counter weight 31 are separated, the belt is connected with a steel wire of a steel wire roller 42, and the power system of the movable driving mechanism 40 is used for pulling the belt 30 (or additionally connecting the well pipe lifting belt 41) and the well pipe elevator to carry out well repairing operation. The dual-purpose of one machine is realized, and the huge investment of one set of workover rig and transportation, installation and maintenance guarantee is saved.

It should be noted that although one embodiment of the present invention has been shown and described herein, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents, which are modified to incorporate the teachings of the present invention into the apparatus of an integrated pump/workover rig.
