Description

Technical Field

[0001] This utility model relates to the field of oil drilling and production technology, and in particular to an oil drilling wellhead fracturing device. Background Technology

[0002] In the petroleum industry, fracturing refers to a method of creating fractures in oil and gas reservoirs using hydraulic force during oil or gas production; it is also known as hydraulic fracturing. Fracturing equipment used in the fracturing process, such as fracturing pumps, is one of the main pieces of equipment for increasing oil production. With increasing demands for oil production rates, fracturing pumps are developing towards higher power, higher pressure, larger displacement, and larger volume. However, existing wellhead fracturing equipment in oil drilling and production suffers from the following problems during use: After being transported to the drilling and production site, the fracturing equipment cannot be easily moved to the working position, resulting in cumbersome transportation.

[0003] In existing technology patent CN216950335U, a fracturing device for oil drilling and production wellheads is disclosed. Through a support device, the fracturing equipment can be easily moved off the fracturing truck. This allows the fracturing equipment to be easily transported from the fracturing truck before it is moved to the drilling site.

[0004] After the fracturing mechanism is positioned, the fixed base plate is moved using rollers. When one roller is suspended in the air, it is supported by a support wheel and rollers. Then, the drive motor at one end drives the internal threaded tube to rotate, and through the threaded rod, the movable rod moves, bringing the bottom roller into contact with the ground. The fixed base plate is then moved further, suspending the other roller in the air and bringing it into contact with the ground. This allows the fracturing mechanism to be easily transported to the working position, improving the ease of transport and solving the problem of cumbersome handling.

[0005] However, in the existing methods described above, when moving the equipment, stones and impurities are easily trapped on the surface of the rollers, which can easily cause the equipment to bounce when moving, greatly affecting the stability of the equipment. Utility Model Content

[0006] The purpose of this utility model is to provide an oil drilling wellhead fracturing device that solves the problem in the prior art where stones and impurities easily accumulate on the surface of the rollers when moving equipment, which easily causes the equipment to bounce during movement and greatly affects the stability of the equipment.

[0007] To achieve the above objectives, this utility model employs an oil drilling and production wellhead fracturing device, comprising a fixed base plate, fracturing equipment, multiple rollers, multiple sets of stabilizing components, and multiple sets of cleaning components. All rollers are connected to the fixed base plate and are located below it. The fracturing equipment is fixedly connected to the fixed base plate and is located above it. Multiple sets of stabilizing components are disposed on the outer wall of the fixed base plate, and multiple sets of cleaning components are disposed on the fixed base plate.

[0008] The cleaning assembly includes a pushing module, a support plate, a sliding rod, a return spring, a mounting plate, and a scraper. The fixed base plate has a sliding groove. The pushing module is connected to the fixed base plate and located above the sliding groove. The support plate is connected to the pushing module and located within the sliding groove. The sliding rod is slidably connected to the support plate and passes through the support plate. The mounting plate is fixedly connected to the support plate. The scraper is fixedly connected to the mounting plate and located on the outer side wall of the mounting plate. The two ends of the return spring are fixedly connected to the support plate and the mounting plate respectively, and are sleeved on the outside of the sliding rod.

[0009] The pushing module includes a bracket, a lead screw, an I-shaped slider, and a drive motor. The bracket is fixedly connected to the fixed base plate and located above the fixed base plate. Both ends of the lead screw are rotatably connected to the bracket. The bracket has a limiting groove. The I-shaped slider is sleeved on the outside of the lead screw and threadedly engaged with the lead screw. The I-shaped slider is slidably connected to the bracket and located within the limiting groove. The drive motor is fixedly connected to the bracket and located on the outer wall of the bracket. The output end of the drive motor is connected to the lead screw.

[0010] The cleaning component also includes a baffle, which is fixedly connected to the support plate and located on the outer side wall of the support plate.

[0011] The cleaning component further includes a limiting block, which is fixedly connected to the slide rod and located at the end of the slide rod away from the mounting plate.

[0012] The stabilizing component includes a fixed plate, a sleeve, a threaded rod, a handwheel, and a fixing pin. The fixed plate is fixedly connected to the fixed base plate and is located on the outer side wall of the fixed base plate. The sleeve is fixedly connected to the fixed plate and passes through the fixed plate. The threaded rod is threadedly engaged with the sleeve and passes through the sleeve. The handwheel is fixedly connected to the upper end of the threaded rod, and the fixing pin is fixedly connected to the lower end of the threaded rod.

[0013] This utility model discloses an oil drilling and fracturing device. When the mobile equipment detects stones or impurities on the roller, it activates the pushing module on the fixed base plate. The support plate is moved laterally within the sliding groove by the pushing module, and the scraper moves closer to the roller, scraping the roller surface. Simultaneously, the scraper drives the sliding rod to slide on the support plate. The extension and retraction of the return spring causes the scraper to continuously clean the roller surface. After cleaning is completed, the screw is reversed, moving the scraper away from the roller. This method facilitates the cleaning of stones and impurities retained on the roller surface, prevents equipment from shaking during movement, and improves the stability of the equipment.

Detailed Implementation

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0021] Please see Figures 1-4 This utility model provides an oil drilling wellhead fracturing device, comprising a fixed base plate 101, a fracturing device 102, multiple rollers 103, multiple sets of stabilizing components, and multiple sets of cleaning components. The multiple rollers 103 are all connected to the fixed base plate 101 and are all located below the fixed base plate 101. The fracturing device 102 is fixedly connected to the fixed base plate 101 and is located above the fixed base plate 101. The multiple sets of stabilizing components are all disposed on the outer side wall of the fixed base plate 101, and the multiple sets of cleaning components are disposed on the fixed base plate 101.

[0022] The cleaning assembly includes a pushing module, a support plate 104, a sliding rod 105, a return spring 106, a mounting plate 107, and a scraper 108. The fixed base plate 101 has a sliding groove 109. The pushing module is connected to the fixed base plate 101 and located above the sliding groove 109. The support plate 104 is connected to the pushing module and located within the sliding groove 109. The sliding rod 105 is slidably connected to the support plate 104 and passes through the support plate 104. The mounting plate 107 is fixedly connected to the support plate 104. The scraper 108 is fixedly connected to the mounting plate 107 and located on the outer side wall of the mounting plate 107. The two ends of the return spring 106 are fixedly connected to the support plate 104 and the mounting plate 107 respectively, and are sleeved on the outside of the sliding rod 105.

[0023] In this embodiment, when the mobile device detects stones or impurities on the roller 103, it activates the push module on the fixed base plate 101. The support plate 104 is moved laterally within the sliding groove 109 by the push module, and the scraper 108 moves closer to the roller 103. The scraper 108 scrapes the surface of the roller 103, and at the same time, the scraper 108 drives the slide rod 105 to slide on the support plate 104. The return spring 106 extends and retracts, causing the scraper 108 to continuously clean the surface of the roller 103. After cleaning is completed, the lead screw 111 is reversed, causing the scraper 108 to move away from the roller 103. By adopting the above method, it is possible to easily clean stones and impurities stuck on the surface of the roller 103, prevent the equipment from bumping during movement, and improve the stability of the equipment.

[0024] Furthermore, the pushing module includes a bracket 110, a lead screw 111, an I-shaped slider 112, and a drive motor 113. The bracket 110 is fixedly connected to the fixed base plate 101 and is located above the fixed base plate 101. Both ends of the lead screw 111 are rotatably connected to the bracket 110. The bracket 110 has a limiting groove 114. The I-shaped slider 112 is sleeved on the outside of the lead screw 111 and threadedly engaged with the lead screw 111. The I-shaped slider 112 is slidably connected to the bracket 110 and is located within the limiting groove 114. The drive motor 113 is fixedly connected to the bracket 110 and is located on the outer side wall of the bracket 110. The output end of the drive motor 113 is connected to the lead screw 111.

[0025] In this embodiment, when the scraper 108 moves closer to the roller 103, the drive motor 113 on the bracket 110 is activated. The drive motor 113 controls the lead screw 111 to rotate within the bracket 110. Since the I-shaped slider 112 is threadedly engaged with the lead screw 111, the I-shaped slider 112 is driven by the lead screw 111 to move laterally within the sliding groove 109. The support plate 104 is also driven to move laterally by the I-shaped slider 112. The scraper 108 gradually moves closer to the roller 103, and the scraper 108 scrapes away the impurities and stones retained on the surface of the roller 103.

[0026] Furthermore, the cleaning assembly also includes a baffle 115, which is fixedly connected to the support plate 104 and located on the outer side wall of the support plate 104.

[0027] In this embodiment, by providing the baffle 115, when cleaning the roller 103, the baffle 115 can block the impurities and stones generated during the cleaning of the roller 103, preventing them from flying towards the fixed base plate 101.

[0028] Furthermore, the cleaning assembly also includes a limiting block 116, which is fixedly connected to the slide rod 105 and located at the end of the slide rod 105 away from the mounting plate 107.

[0029] In this embodiment, by providing the limiting block 116 on the slide rod 105, the limiting block 116 is used to prevent the slide rod 105 from detaching from the support plate 104.

[0030] Further, the stabilizing component includes a fixing plate 117, a sleeve 118, a threaded rod 119, a handwheel 120, and a fixing pin 121. The fixing plate 117 is fixedly connected to the fixing base plate 101 and is located on the outer side wall of the fixing base plate 101. The sleeve 118 is fixedly connected to the fixing plate 117 and passes through the fixing plate 117. The threaded rod 119 is threadedly engaged with the sleeve 118 and passes through the sleeve 118. The handwheel 120 is fixedly connected to the upper end of the threaded rod 119, and the fixing pin 121 is fixedly connected to the lower end of the threaded rod 119.

[0031] In this embodiment, after the equipment is moved to the working area, the handwheels 120 are rotated at the four corners of the fixed base plate 101. The handwheels 120 drive the threaded rod 119 to rotate. Since the threaded rod 119 is threadedly engaged with the sleeve 118, the threaded rod 119 moves downward, and the fixing pin 121 moves along with it until the fixing pin 121 enters the ground, so that the fixed base plate 101 is fixed above the ground.

[0032] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
