Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] The core of the present utility model is to provide an installation and positioning device for drilling equipment, which uses a pin shaft to align the equipment bottom beam with the skid base, and uses a compression assembly to press and fix the equipment bottom beam on the skid base, improving the assembly efficiency and assembly accuracy.

[0027] The installation and positioning device for drilling equipment provided by the present utility model includes a positioning assembly 1 and a compression assembly 2. The positioning assembly 1 and the compression assembly 2 are respectively arranged on the equipment bottom beam 40 on both sides of the drilling equipment. The compression assembly 2 is used to press the equipment bottom beam 40 onto the skid base 10;

[0028] The positioning assembly 1 includes a pin shaft 13, a fixed bushing 11 arranged on the skid base 10, and a positioning bushing 12 arranged on the equipment bottom beam 40. The pin shaft 13 is sleeved in the fixed bushing 11 and the positioning bushing 12 to connect and position the positioning bushing 12 and the fixed bushing 11. The fixed bushing 11 or the positioning bushing 12 is provided with a positioning pin hole for installing a positioning pin 14, and the positioning pin 14 is used to limit the axial movement of the pin shaft 13.

[0029] To ensure the installation stability of the drilling equipment, usually two equipment bottom beams 40 of the drilling equipment are installed on the skid base 10; the positioning assembly 1 and the pressing assembly 2 are respectively arranged on the equipment bottom beams 40 on both sides of the drilling equipment, and are used to connect the equipment bottom beams 40 and the skid base 10 on both sides, so as to realize the installation and positioning of the drilling equipment and the skid base 10.

[0030] The quantity and distribution of the positioning assembly 1 and the pressing assembly 2 need to be determined according to the quantity and distribution of the equipment bottom beams 40 used in the installation of the drilling equipment in actual production;

[0031] Taking the positioning and installation of the mud pump 30 as an example, please refer to Figure 3 , the mud pump 30 is arranged on the skid base 10 of the pump unit through two equipment bottom beams 40, and the input shaft of the mud pump 30 is connected to the output shaft of the diesel engine 20. A set of positioning assembly 1 and a set of pressing assembly 2 are respectively arranged at both ends in the extending direction of the mud pump 30.

[0032] The positioning assembly 1 is used to align the equipment bottom beam 40 and the skid base 10. Through the pin shaft 13 sleeved in the fixed sleeve 11 and the positioning sleeve 12, the axes of the fixed sleeve 11 and the positioning sleeve 12 can be made collinear, so as to realize the alignment of the equipment bottom beam 40 and the drilling equipment.

[0033] The fixed sleeve 11 is arranged on the skid base 10, and the positioning sleeve 12 is arranged on the equipment bottom beam 40. The two can be installed by welding, or fixed by detachable methods such as bolt connection and pin connection;

[0034] Considering that bolt connection and pin connection require drilling operations on the skid base 10 and the equipment bottom beam 40 and are relatively complex, it is preferably set that the fixed sleeve 11 and the positioning sleeve 12 are welded to the skid base 10 or the equipment bottom beam 40, or installed by a clamping method.

[0035] The pin shaft 13 is used to connect the fixed sleeve 11 and the positioning sleeve 12. During installation, the pin shaft 13 is inserted into one of the fixed sleeve 11 and the positioning sleeve 12. After the pin holes of the fixed sleeve 11 and the positioning sleeve 12 are basically aligned, the equipment bottom beam 40 is pushed towards the direction close to the fixed sleeve 11 by a hydraulic device or the like until the positioning sleeve 12 abuts against the fixed sleeve 11, and the alignment of the equipment bottom beam 40 and the skid base 10 is completed.

[0036] It should be noted that considering that it is more difficult to push the skid base 10 than to push the drilling equipment, the pin shaft 13 is usually arranged in the fixed sleeve 11, and the equipment bottom beam 40 is pushed towards the direction close to the fixed sleeve 11.

[0037] The pin shaft 13 can be specifically set as a cylindrical pin or a tapered pin. To facilitate the movement of the pin shaft 13 within the fixed bushing 11 or the positioning bushing 12, it is preferably set as a tapered pin. The tapered structure at the head of the tapered pin has a guiding effect, which has a guiding effect on the fixed bushing 11 or the positioning bushing 12.

[0038] To prevent the pin shaft 13 from axially moving after alignment, the fixed bushing 11 and / or the positioning bushing 12 are provided with mounting pin holes for mounting the positioning pin 14. The positioning pin 14 can be inserted into the pin shaft 13 after passing through the above-mentioned positioning pin holes, thereby restricting the axial displacement of the pin shaft 13.

[0039] The material and size of the positioning pin 14 are determined according to the size of the pin shaft 13 and the axial load borne by the pin shaft 13 in actual production, so as to ensure the shear strength of the positioning pin 14, the stiffness of the pin shaft 13, and the compressive strength.

[0040] The pressing assembly 2 is used to connect and fix the equipment bottom beam 40 and the skid base 10 after alignment. It can open holes in the lower wing plate of the equipment bottom beam 40 and use fasteners such as fastening bolts 22 and connecting pins to connect and fix the lower wing plate and the skid base 10; or it can be provided with a pressing plate 21 and use fasteners to press the pressing plate 21 onto the skid base 10.

[0041] During the initial installation, the drilling equipment is assembled and connected to the corresponding equipment on the skid base 10 in place. Then, the positioning assembly 1 is installed on the outer side of one side of the equipment bottom beam 40. Finally, the pressing assembly 2 is installed on the outer side of the other side of the equipment bottom beam 40.

[0042] When disassembling the equipment, first disassemble the pressing assembly 2, and then remove the positioning pin 14. Use a hydraulic device or the like to push the pin shaft 13 or the equipment bottom beam 40 to separate the positioning bushing 12 of the equipment bottom beam 40 from the fixed bushing 11 of the skid base 10, so that the drilling equipment is separated from the positioning assembly 1. At this time, the equipment can be transported by means of hoisting, moving, etc.

[0043] When the equipment arrives at the well site for installation, first insert the pin shaft 13 into the fixed bushing 11 of the skid base 10. Then, hoist and place the drilling equipment on the skid base 10 so that the pin holes of the positioning bushing 12 and the fixed bushing 11 of the equipment bottom beam 40 are basically aligned. Then, use a hydraulic device or the like to push the equipment bottom beam 40 in the direction close to the fixed bushing 11 to make the positioning bushing 12 abut against the fixed bushing 11. At this time, the drilling equipment is in place. Fix the axial position of the pin shaft 13 with the positioning pin 14 and install the pressing assembly 2 to complete the positioning and installation of the drilling equipment.

[0044] To ensure smooth movement of the pin shaft 13 during loading and unloading, it is preferably set that the positioning bushing 12 is provided with an oil storage groove, and an oil cup interface 121 is provided on the outer peripheral part of the positioning bushing 12. The oil cup interface 121 is communicated with the oil storage groove, which facilitates the daily oil injection and maintenance of the positioning bushing 12.

[0045] In this embodiment, a pin shaft 13 is used to realize the connection and alignment between the equipment bottom beam 40 and the skid base 10, and then the equipment bottom beam 40 is pressed and fixed on the skid base 10 by a pressing component 2. Compared with the existing manual visual operation, the alignment efficiency is significantly improved, the assembly efficiency is improved, and at the same time, the alignment accuracy between the equipment bottom beam 40 and the skid base 10 is ensured, and the assembly accuracy is improved.

[0046] Considering the situation where the orientation of the pin shaft 13 and the fixed pin hole is not aligned, at this time, the pin shaft 13 needs to be rotated. In order to facilitate the rotation of the pin shaft 13, it is preferably set that a matching part is provided at the bottom of the pin shaft 13, and the matching part is used to cooperate with a wrench to screw the pin shaft 13.

[0047] On the basis of the above embodiment, considering that it is difficult to ensure that the axis of the positioning bushing 12 is parallel to the lower wing plate by direct welding, a limiting plate 15 can be vertically provided on the web of the equipment bottom beam 40. The limiting plate 15 is parallel to the lower wing plate of the equipment bottom beam 40, and the positioning bushing 12 is clamped between the limiting plate 15 and the lower wing plate of the equipment bottom beam 40.

[0048] The limiting plate 15 is preferably welded to the web of the equipment bottom beam 40, or can also be connected to the web by fasteners; compared with directly welding the positioning bushing 12 to the web, the welding seam between the limiting plate 15 and the web is a straight line segment, the welding operation is easier, and the welding quality is high.

[0049] In order to reduce the impact when the positioning bushing 12 of the equipment bottom beam 40 abuts against the fixed bushing 11, a cushion plate 16 can be provided on the side of the limiting plate 15 relatively close to the web. The cushion plate 16 can be set as a rigid cushion plate or a flexible cushion plate;

[0050] When the cushion plate 16 is a rigid cushion plate, a cushion plate 16 is provided between the limiting plate 15 and the web, the cushion plate 16 is welded to the outer side of the web, and the limiting plate 15 is vertically welded to the outer side of the cushion plate 16, as Figure 1 shown;

[0051] When the cushion plate 16 is a flexible cushion plate such as a rubber pad, etc., it is preferably set that a cushion plate 16 is provided on the side of the limiting plate 15 relatively close to the web. The cushion plate 16 is provided with a through hole for installing the limiting plate 15. The cushion plate 16 is sleeved outside the limiting plate 15, and the cushion plate 16 is welded or adhesively connected to the web to prevent a gap between the cushion plate 16 and the web from affecting the buffering effect.

[0052] On the basis of the above embodiment, the structure of the pressing component 2 is defined. The pressing component 2 includes a pressing plate 21 for abutting against the lower wing plate of the equipment bottom beam 40, and the pressing plate 21 is pressed and arranged on the skid base 10 through a fastening bolt 22.

[0053] Compared with directly connecting the lower wing plate to the pry base 10 through fasteners, punching of the lower wing plate is reduced or even avoided, which not only simplifies the initial installation process of the pressing assembly 2, but also reduces the impact of punching on the strength of the equipment bottom beam 40.

[0054] To avoid punching on the lower wing plate, the pressing plate 21 can be set as an L-shaped pressing plate. The L-shaped pressing plate includes a horizontal plate for abutting against the lower wing plate and a vertical plate for abutting against the pry base 10. The fastening bolt 22 is arranged on the side of the horizontal plate relatively far from the lower wing plate, as Figure 1 shown;

[0055] The pressing plate 21 can also be set as a Z-shaped pressing plate. The Z-shaped pressing plate includes a vertical plate and horizontal plates respectively arranged on both sides of the vertical plate. One of the horizontal plates is used for abutting against the lower wing plate, and the other is used for abutting against the pry base 10. The fastening bolt 22 is arranged on the horizontal plate abutting against the pry base 10.

[0056] In order to increase the contact area between the pressing plate 21 and the lower wing plate to improve the pressing stability and reliability, preferably, a positioning step can be provided on the side of the pressing plate 21 for abutting against the lower wing plate. The positioning step is used for abutting against the outer side surface of the lower wing plate. Compared with the pressing plate 21 only abutting against the upper surface of the lower wing plate, the contact area between the pressing plate 21 and the lower wing plate is increased, and the pressing stability of the pressing assembly 2 is improved.

[0057] In this specification, each embodiment is described in a progressive manner. The key point of each embodiment is to illustrate the differences from other embodiments. The same or similar parts among the embodiments can be referred to each other.

[0058] The above has introduced in detail the installation and positioning device for drilling equipment provided by the present invention. Specific examples are used herein to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention.
