Description

Drilling pump clamps for easy disassembly

technical field

The utility model belongs to the technical field of oil and gas drilling and production equipment, and relates to a clamp of a drilling pump which is easy to assemble and disassemble.

Background technique

The clamp is an important connecting part of the drilling pump, and its main function is to connect the middle tie rod of the power end and the piston rod of the liquid power end together. The piston rod is one of the wearing parts of the drilling pump. When replacing the piston rod, the clamp must be disassembled. The convenience of disassembly and assembly restricts the maintenance and use efficiency of the drilling pump. At present, the clamps commonly used in drilling pumps are shown in Figure 1. This structure has the following disadvantages: it is inconvenient to disassemble and assemble, and two bolts need to be tightened and tightened during maintenance operations, which is time-consuming and laborious, which will inevitably affect the working efficiency of the drilling pump and even the entire drilling rig.

Contents of the invention

The purpose of the utility model is to provide a drilling pump clamp that is easy to assemble and disassemble, so as to solve the problem of time-consuming and labor-intensive disassembly and assembly of the clamp in the prior art.

The technical solution adopted by the utility model is, a drilling pump clamp that is easy to disassemble, including an upper lobe and a lower lobe, both of which are provided with two fixed ends, and the fixed ends on the same side of the upper and lower lobe The front and rear sides are respectively provided with a connecting plate, the lower perforations of the front and rear connecting plates are jointly hinged with the lower flap through pin one, and the upper perforations of the front and rear connecting plates are jointly hinged with the upper flap through pin two;

The fixed end on the other side of the upper and lower petals adopts a buckle structure, that is, a swing bolt is installed on the lower petal through a pin shaft three, and a bayonet corresponding to the swing bolt is opened on the upper petal, and the outer end of the swing bolt is Installed with nuts.

The easy-to-disassemble drilling pump clamp of the utility model is also characterized in that:

A shaft retaining ring is respectively installed at the two ends of pin shaft one, pin shaft three and pin shaft two.

Nuts are provided with corresponding backing plates.

The beneficial effect of the utility model is that it is only necessary to operate a bolt when disassembling and assembling the hoop to complete the disengagement or connection of the intermediate tie rod and the piston rod, which saves time and effort, and is simple and reliable, so as to achieve rapid maintenance of the drilling pump and effectively reduce the The labor intensity of workers is reduced, and the maintenance and use efficiency of drilling pumps are improved.

detailed description

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

As shown in FIG. 1 , the structure of the clamp in the prior art is that it includes an upper petal 1 and a lower petal 2 of the hoop, and the upper petal 1 and the lower petal 2 are fastened together and fixedly connected by two sets of bolts. When installing, first connect the middle tie rod and the positioning platform of the piston rod together, then place the upper lobe 1 and the lower lobe 2 at the joint between the middle tie rod and the piston rod, and then tighten two groups of bolts. When disassembling, first loosen two sets of bolts, and then separate the upper petal 1 and the lower petal 2 of the clamp.

As shown in Fig. 2 and Fig. 3, the structure of the present utility model is to include an upper lobe 1 and a lower lobe 2, the upper lobe 1 and the lower lobe 2 are all provided with two fixed ends, the same side of the upper lobe 1 and the lower lobe 2 The front and rear sides of the fixed end are respectively provided with a connecting plate 3, the lower perforations of the front and rear connecting plates 3 are jointly hinged with the lower petal 2 through the pin one 4, and the upper perforations of the front and rear connecting plates 3 are jointly hinged with the upper petal 1 through the pin two 9;

The fixed end on the other side of the upper petal 1 and the lower petal 2 adopts a buckle structure, that is, the joint bolt 6 is installed on the lower petal 2 through the pin shaft 3 10, and the bayonet corresponding to the joint bolt 6 is opened on the upper petal 1 , The upper end (outer end) of the swing bolt 6 is equipped with a nut 7, and the nut 7 is equipped with a corresponding backing plate 8.

A shaft retaining ring 5 is respectively installed at pin one 4, pin two 9 and pin three 10 two ends to realize spacing.

The usage method of the present utility model is: first make the upper petal 1 and the lower petal 2 of the hoop buckle on the joint between the middle pull rod and the piston rod, then rotate the joint bolt 6 around the pin shaft 3 10 into the bayonet of the upper petal 1, Install backing plate 8, tighten nut 7, and get final product. The removal steps are reverse to the installation steps.
