[0034] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0035] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0036] For ease of description, spatial relative terms may be used herein to describe the relative positional relationship or movement of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip or a posture change or a motion state change, then these directional indications also change accordingly, for example: an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." may include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative descriptors used herein are interpreted accordingly.

[0037] In the prior art, since the valve box of the plunger pump 200 is relatively high, the operator needs to stand on the pedal provided with the plunger pump 200 to disassemble the valve box so as to inspect and repair the plunger pump 200. Figure 1 As shown, the existing maintenance platform uses a flip-type pedal 300. When disassembling the valve box, the pedal needs to be flipped 90 degrees and straightened to a horizontal state, and the operator stands on the pedal to perform the disassembly operation. During the disassembly process, residual water and other liquids in the valve box will flow out of the valve box and scatter to the on-site operation ground, causing pollution to the operation area.

[0038] In order to solve the technical problem in the prior art that conventional pedals cannot collect residual water in the valve box, causing the residual water to pollute the working area, the present application provides a telescopic water collection and maintenance platform 100, which can collect residual water and other liquids during the disassembly process of the plunger pump valve box to avoid pollution to the working area.

[0039] Figures 2 to 3 A telescopic water collection and maintenance platform 100 provided in an embodiment of the present application includes a guide rail 1, a water collection tray 2 and a pedal 3. The guide rail 1 is horizontally arranged below the valve box of the plunger pump 200; the water collection tray 2 is slidably arranged on the guide rail 1 along the horizontal direction, and a water collection groove 21 is provided on the side of the water collection tray 2 facing the valve box of the plunger pump 200; the pedal 3 is arranged in the water collection groove 21 for the operator to step on.

[0040] like Figure 4As shown, when the operator needs to inspect the valve box of the plunger pump 200, the water receiving tray 2 is manually pulled out to slide the water receiving tray 2 away from the plunger pump 200. The operator can stand on the pedal 3 to disassemble the valve box of the plunger pump 200 and inspect it. The residual water and other liquids can be collected by the water receiving tray 2 to avoid contamination of the working area. At the same time, the telescopic water receiving tray 2 can be stored under the valve box of the plunger pump 200 to save layout space.

[0041] In some embodiments, Figure 5 and Figure 6 As shown, the water receiving tray 2 is provided with a water outlet 22 connected to the water receiving groove 21 at one end of the sliding direction thereof, and a ball valve 23 is provided at the water outlet 22. By opening the ball valve 23, the collected residual water and other liquids can be discharged to prevent excessive overflow of the liquid.

[0042] In some embodiments, the pedal 3 includes a grid plate 31 and crisscrossed transverse support plates 32 and longitudinal support plates 33 . One side of the grid plate 31 overlaps the transverse support plates 32 and the longitudinal support plates 33 , and the other side is flush with the water tray 2 .

[0043] The liquid flowing out of the valve box of the plunger pump 200 is scattered onto the pedal 3 and flows into the water receiving tank 21 through the partition. On the one hand, it is not easy to dirty the shoes of the operators, and on the other hand, it is conducive to the collection of the liquid.

[0044] Optionally, the grating 31 may be a steel grating 31 to ensure the supporting force of the pedal 3 .

[0045] Furthermore, both ends of the transverse support plate 32 and both ends of the longitudinal support plate 33 are respectively in contact with the side walls of the water receiving tank 21, and a plurality of water holes 321 communicating with the water outlet 22 are arranged at intervals on the transverse support plate 32 and the longitudinal support plate 33. By providing the water holes 321, the liquid collected in the water receiving tank 21 can flow to the water outlet 22 through the water holes 321, and then be discharged from the water receiving tank 21 through the ball valve 23.

[0046] The water hole 321 can be configured to be circular, square, oval, etc., and is not specifically limited here.

[0047] In some embodiments, Figures 7 to 10 As shown, the guide rail 1 is provided with positioning components at both ends of its length direction for limiting the movement of the water receiving tray 2. By providing the positioning components, the water receiving tray 2 can be prevented from slipping off the guide rail 1, so as to avoid safety accidents during maintenance by operators.

[0048] In an optional embodiment, the positioning assembly includes a positioning plate 14 arranged on the outside of the guide rail 1, an opening 111 is arranged on the guide rail 1, and a limiting block 15 is detachably connected to the positioning plate 14, and the limiting block 15 includes an integrally formed connecting portion and a limiting portion, so that the cross-section of the limiting block 15 is in a "convex" shape, the connecting portion of the limiting block 15 is connected to the positioning plate 14, and the limiting portion of the limiting block 15 extends into the opening 111; a slider 24 is provided on the water receiving tray 2, which is slidably connected to the guide rail 1, and the slider 24 is preferably arranged at the end of the water receiving tray 2 away from the water outlet 22, and the orthographic projection of the limiting block 15 on the transverse center plane 101 at least partially covers the orthographic projection of the slider 24 on the transverse center plane 101.

[0049] By providing the limit blocks 15 , the slider 24 is always located between the two limit blocks 15 during the sliding process, that is, the two limit blocks 15 limit the moving stroke of the slider 24 .

[0050] Furthermore, the positioning plate 14 is provided with a threaded hole 141, and a fastener 142 is threadedly connected to the threaded hole 141, and the limit block 15 is installed on the positioning plate 14 through the fastener 142. The fastener 142 can be a threaded fastener such as a bolt or a self-tapping screw.

[0051] In some embodiments, Figure 4 As shown, a longitudinal reinforcing plate 34 is mounted on the transverse supporting plate 32 , and two ends of the longitudinal reinforcing plate 34 are respectively in contact with the side walls of the water receiving groove 21 to enhance the structural strength of the water receiving tray 2 , thereby enhancing the supporting force of the pedal 3 .

[0052] In some embodiments, Figure 6 As shown, the guide rail 1 includes a connected bending plate 11 and a rectangular plate 12, the rectangular plate 12 is fixedly arranged on the bottom skid of the plunger pump 200, and the bending plate 11 is provided with a slide groove 112 slidably connected to the water receiving tray 2. Optionally, the bending plate 11 and the rectangular plate 12 are welded.

[0053] Optionally, a reinforcing rib 13 is provided between the bending plate 11 and the rectangular plate 12 , one side of the reinforcing rib 13 is fixedly connected to the bending plate 11 , and the other side thereof is fixedly connected to the rectangular plate 12 , so as to improve the structural strength of the guide rail 1 .

[0054] Alternatively, if Figure 1 As shown, a handle 25 is provided on the water receiving tray 2 to facilitate the user to operate the pedal 3 .

[0055] It should be noted that the telescopic water collection and maintenance platform 100 provided in the embodiment of the present application is intended to provide a maintenance pedal and collect liquid at the same time. It is not limited to use in oil and gas field drilling and production operating equipment, but can also be used in other operating equipment that requires a maintenance pedal, such as equipment maintenance pedals in workshops and factories, maintenance pedals in dock operations, etc., which will not be repeated here.
