Detailed Implementation

[0018] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

The traveling assembly S2 includes a pair of opposing lifting units 10, and a pair of detachable traveling units 20 are provided on the outer side of the lifting units 10. The lifting units 10 cause the skid body S1 to rise or fall, and the traveling units 20 cause the skid body S1 to move forward, backward, or rotate.

[0020] like Figure 4 and Figure 5 As shown, the lifting unit 10 includes a horizontally arranged outer crossbeam sleeve 11, and a movable inner crossbeam sleeve 12 is provided inside the outer crossbeam sleeve 11. The inner crossbeam sleeve 12 is connected to the outer crossbeam sleeve 11 through a first drive cylinder 14, and a vertically arranged lifting cylinder body 13 is provided at the end of the inner crossbeam sleeve 12.

[0021] The walking unit 20 includes a longitudinally arranged slipper drive cylinder 21. The bottom of the slipper drive cylinder 21 is provided with a detachable slipper unit 23. A slipper steering unit 2K is provided on one side of the slipper drive cylinder 21. The slipper steering unit 2K drives the slipper unit 23 to rotate.

[0022] like Figures 6 to 8 As shown, the slipper steering unit 2K includes a horizontally arranged steering bracket 26, which is located at the bottom of the cylinder rod of the slipper drive cylinder 21. The far end of the steering bracket 26 is provided with a longitudinally arranged guide rod 24. The upper part of the guide rod 24 is provided with a guide seat 25, which is welded to the outer side of the outer crossbeam sleeve 11 of the lifting unit 10.

The rotating crossbeam 27 is rotatably connected to the cylinder bracket 28, and the rotating cylinder 29 is swingably mounted on the cylinder bracket 28. The rotating cylinder 29 drives the slipper unit 23.

[0023] In addition, several connecting flanges 111 are provided on the side of the outer crossbeam sleeve 11. The guide seat 25 is provided with guide holes 251.

[0024] The rotating crossbeam 27 includes a first crossbeam through hole 271 and a second crossbeam through hole 272. The top of the cylinder bracket 28 is provided with a bracket connecting pin 281, and the side wall of the cylinder bracket 28 is provided with a bracket through hole 282. The head of the rotating cylinder 29 is provided with a rotating cylinder ring 292, and the tail of the rotating cylinder 29 is provided with a rotating cylinder retaining protrusion 291. The first crossbeam through hole 271 is engaged with the guide rod 24, the second crossbeam through hole 272 is engaged with the bracket connecting pin 281, the bracket through hole 282 is engaged with the rotary cylinder latch 291, and the rotary cylinder latch 291 is engaged with the slipper unit 23.

[0025] like Figure 9 As shown, the slipper unit 23 includes a bottom shell 231, a slide rail 232 is provided inside the bottom shell 231, and a slidable slide seat 234 is provided on the slide rail 232. The slide seat 234 is fixedly connected to the end of the cylinder rod of the slipper drive cylinder 21. A pair of travel cylinders 233 are provided inside the bottom shell 231. The travel cylinders 233 drive the slide seat 234 to slide along the slide rail 232.

[0026] The bottom shell 231 has a pair of cylinder mounting lugs 2311 inside. One end of the traveling cylinder 233 has a first connector 2331, and the other end of the traveling cylinder 233 has a second connector 2332. The upper surface of the slide 234 has a rod-shaped drive shaft protrusion 2343 and a slide flange 2342. Both sides of the slide 234 have sliding connecting lugs 2344. The cylinder mounting lug 2311 mates with the first connector 2331, the second connector 2332 mates with the sliding connecting lug 2344, the drive shaft protrusion 2343 mates with the rotating cylinder ring 292, and the slide flange 2342 mates with the cylinder rod of the slide shoe drive cylinder 21.

[0027] In addition, the upper surface of the slide rail 232 is provided with a dovetail guide bar 2321, and the lower surface of the slide block 234 is provided with a dovetail guide groove 2341, which cooperates with the dovetail guide bar 2321.

[0028] The working mode of the skid unit 23 of the fracturing pump skid self-propelled device used for relocation without hoisting is described below.

[0029] like Figure 10 As shown, when the sliding shoe unit 23 starts to move, firstly, the traveling cylinder 233 is activated and extends, while the slide block 234 remains stationary. Under the push of the traveling cylinder 233, the bottom shell 231 moves along direction F1, completing one step of the sliding shoe unit 23's movement. By repeating the above operation, multiple steps of the sliding shoe unit 23 can be completed.

[0030] The following describes the working method of the self-propelled fracturing pump skid used for relocation without hoisting.

[0031] like Figure 11 As shown, the bottom of the skid S1 is in contact with the ground of the working surface, and the equipment on the skid S1 is in normal use.

[0032] like Figure 12 As shown, when the pry bar S1 needs to be moved, the following steps should be followed: Step S1: The four sliding shoe drive cylinders 21 rise synchronously, and the bottom of the skid body S1 leaves the ground; In step S2, the four sliding shoe units 23 start moving synchronously. Thus, the lever body S1 completes one step of movement along direction F2, that is, the length direction of the lever body S1. Step S3: Repeat step S2. Thus, the skid S1 moves along direction F2 for multiple steps until the skid S1 moves to the side of the flatbed truck P. Step S4: The four sliding shoe drive cylinders 21 retract synchronously, and the bottom of the skid body S1 contacts the ground; Step S5: The four lifting cylinders 13 are raised synchronously, so that the bottom height of the skid S1 reaches the height of the flatbed truck P. Step S6: The flatbed truck P reverses, returning to the lower part of the skid S1. The four lifting cylinders 13 retract synchronously, and the skid S1 lands steadily on the flatbed truck P. Once the flatbed truck P has transported the skid S1 to its destination, the unloading of the skid S1 is completed in the same manner.

[0033] It should be noted that, as Figure 14 As shown, if it is necessary to move the skid S1 along direction F3, that is, the width direction of the skid S1, the rotary cylinder 29 can be used to push the sliding shoe unit 23 to rotate 90°, so that the traveling direction of the sliding shoe unit 23 is towards direction F3. It should be noted that the rotary cylinder 29 can push the sliding shoe unit 23 to rotate at a suitable angle as needed, such as 45 degrees or 60 degrees, and is not limited to 90 degrees.

[0034] like Figure 15 and Figure 16 The diagram shows another embodiment of the self-propelled fracturing pump skid for relocation without hoisting. In this embodiment, a bracket clamp 211 is provided on the top of the skid drive cylinder 21 to support the pipeline Q. It should be noted that the pipeline Q needs to be docked with the equipment on the skid S1. At this time, the position of the skid S1 can be precisely adjusted using the traveling unit 20 so that the equipment on the skid S1 is precisely docked with the pipeline Q.

[0035] This invention provides a self-propelled fracturing pump skid for relocation without hoisting. This self-propelled device has a compact structure and can easily move autonomously in all directions, greatly facilitating the unloading and loading of the fracturing pump skid, simplifying its relocation, and significantly reducing the labor intensity of workers. Furthermore, because the self-propelled device can move independently, it greatly facilitates docking with external pipelines, saving time and effort.

[0036] Obviously, the embodiments described above are only some embodiments of this application, and not all embodiments. The accompanying drawings show preferred embodiments of this application, but do not limit the patent scope of this application.
