Description

Technical Field

[0001] This utility model relates to the field of oil drilling and production equipment technology, specifically to a five-cylinder drilling pump reducer support. Background Technology

[0002] Drilling pumps are essential equipment in the oil and gas drilling and production field. Their main function is to provide high-pressure drilling fluid to the bottom of the well. During drilling, the drilling fluid plays a crucial role in transmitting hydraulic power, stabilizing the wellbore and balancing bottom hole pressure, carrying and suspending cuttings, cleaning the bottom hole, and cooling and lubricating the drill string. Currently, the drilling pumps used in oil and gas drilling and mining operations are mainly three-cylinder pumps, with a smaller number being five-cylinder pumps. Three-cylinder pumps, in particular, utilize a traditional technology that integrates the reducer with the pump's power end, eliminating the need for reducer support.

[0003] Due to its special structure and the design of separating the reducer from the pump, the reducer of the five-cylinder drilling pump is a cantilever beam structure on the entire pump. Therefore, when the five-cylinder drilling pump is running, it will generate huge torque load. If the reducer is not supported, it will inevitably be damaged. Therefore, in order to avoid damage to the reducer, a stable support structure for the reducer is urgently needed. Utility Model Content

[0004] The purpose of this utility model is to provide a five-cylinder drilling pump reducer bracket, which is set between the reducer and the base, to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a five-cylinder drilling pump reducer bracket, comprising a connecting base and a reducer mounted on the connecting base, wherein both ends of the reducer are supported on the connecting base by a first bracket and a second bracket respectively; the first bracket and the second bracket each include a first double-ear seat mounted on the connecting base, the first double-ear seat being connected to a right-hand bolt via a first tail cone pin, the right-hand bolt being inserted into the lower end of a connecting rod and threadedly connected to a right-hand round nut welded to the lower end of the connecting rod, a steel pipe being welded to the upper end of the right-hand round nut, and a left-hand round nut being welded to the upper end of the steel pipe, the right-hand round nut, the steel pipe, and the left-hand round nut forming a connecting rod; a left-hand bolt is threadedly connected to the left-hand round nut, the left-hand bolt being connected to a second double-ear seat via a second tail cone pin, the second double-ear seat being provided with a rubber pad and connected to the reducer via screws, washers, and nuts.

[0006] Preferably, a right-handed nut is provided between the right-handed bolt and the right-handed round nut.

[0007] Preferably, a left-handed nut is provided between the left-handed bolt and the left-handed round nut.

[0008] Preferably, a first pin is inserted at the rear end of the first tail cone pin.

[0009] Preferably, a second pin is inserted at the rear end of the second tail cone pin.

[0010] The working process of this utility model is as follows:

[0011] The reducer requires two supports of unequal length, the first and second brackets, to be mounted on the base. First, the first double-eared bracket is welded to the base. Then, the second double-eared bracket, equipped with a rubber pad, is connected to the reducer using screws, washers, and nuts. Next, the right-hand nut and right-hand bolt are fitted together; the left-hand nut and left-hand bolt are fitted together. Then, the connecting rod is screwed onto the right-hand and left-hand bolts. The right-hand bolt is then connected to the first double-eared bracket via the first tail cone pin and secured with the first pin. The left-hand bolt is then connected to the second double-eared bracket via the second tail cone pin and secured with the second pin. The center distance between the first and second double-eared brackets is adjusted by rotating the connecting rod to fully support the reducer. Finally, the right-hand and left-hand nuts are tightened to prevent the connecting rod from loosening.

[0012] The beneficial effects of this utility model are as follows:

[0013] (1) This utility model uses a right-hand bolt and a right-hand round nut for connection and a left-hand bolt and a left-hand round nut for connection and connection, thereby changing the distance between the first double ear seat and the second double ear seat.

[0014] (2) By changing the distance between the first double ear seat and the second double ear seat, this utility model ensures that the reducer is stably supported on the base without being damaged.

[0015] (3) This utility model uses the right-hand nut on the right-hand bolt and the left-hand nut on the left-hand bolt as locking nuts to ensure that the support will not loosen due to vibration during the operation of the equipment and thus fail to play a supporting role.

[0016] (4) The present invention provides a rubber pad between the second double ear seat and the contact surface of the reducer to buffer the vibration caused by the operation of the equipment and reduce the possibility of loosening of bolts and nuts.

[0017] (5) This utility model uses a first tail cone pin, a first pin, a second tail cone pin, a second pin, a screw, a washer, and a nut to connect the various components. The structure is simple, easy to install, disassemble and use, and has high reliability. It is convenient for speed reducer maintenance and other work, and improves technical performance and economic benefits. Attached Figure Description
