Description

Technical Field

[0001] The utility model relates to a turnover mechanism for a pump head cylinder body of a fracturing vehicle, belonging to the technical field of fracturing equipment manufacturing. Background Art

[0002] A fracturing truck is a special vehicle used to inject high-pressure, large-volume fracturing fluid into a well, pressurize the formation and squeeze the proppant into the crack. The most important component on a fracturing truck is the fracturing pump, which is a horizontal three-cylinder high-pressure plunger pump. The pump head cylinder of the fracturing pump is in the shape of a rectangular body. In order to facilitate the processing and assembly of the pump head cylinder, the manufacturer needs to flip it 90 degrees during the processing or assembly process to facilitate subsequent processing or assembly operations; due to the large weight of the pump head cylinder, the existing flipping work is usually lifted by a gantry crane, and then manually assisted by the gantry crane to flip it 90°, and then slowly lowered by the gantry crane to complete the entire flipping operation. In this process, manual participation in supporting the flipping operation is cumbersome, the manual labor is large, the flipping efficiency is low, and during the flipping process, it is easy to injure the staff, and there is a risk of personal safety hazards. Therefore, it is necessary to improve it. Summary of the invention

[0022] As shown in the appendix Figures 1-6 shown

[0023] The tipping mechanism for the pump head cylinder block of the fracturing truck includes a frame 1, a tipping plate, a tipping hydraulic cylinder 2 and a tipping seat. Tipping seats are symmetrically arranged on the frame 1. The tipping seat includes two tipping ear plates 3. The two tipping ear plates 3 are symmetrically arranged on the frame 1. Assembly holes for installing the assembly short shaft 4 are provided on the tipping ear plates 3.

[0024] A tipping plate is movably installed between the tipping seats through the assembly short shaft 4. The assembly short shaft 4 is movably inserted into the assembly holes on the tipping ear plates 3. One end of the assembly short shaft 4 is fixedly connected to the central position of the tipping plate. During operation, the tipping plate can be tipped by 0 - 90° around the axis of the assembly short shaft 4.

[0025] The tipping plate includes a plate body 5, a first limit component and a second limit component. The cross-section of the plate body 5 is in an "L" shape. One end of the inner side of the plate body 5 is equipped with a first limit component. The first limit component includes a first limit plate 6. The first limit plate 6 is arranged on the surface of the plate body 5. Three first assembly grooves 7 are provided on the frame 1 below the first limit plate 6. A first screw 8 is movably installed in the first assembly groove 7 at the middle position. The first screw 8 extends to the outside of the frame 1. A first handle 9 is provided on the first screw 8 extending to the outside of the frame 1. The first screw 8 is threadedly connected to the first limit plate 6. First guide rods 10 are fixedly installed in the first assembly grooves 7 on both sides of the first screw 8. The first guide rods 10 are slidably connected to the first limit plate 6. During operation, by rotating the first handle 9, the first screw 8 is driven to rotate. When the first screw 8 rotates, the first limit plate 6 is driven to slide along the axial direction of the first guide rod 10.

[0026] At the other end inside the plate body 5, a second limiting component is installed. The second limiting component includes a second limiting plate 11. The second limiting plate 11 is arranged on the surface of the plate body 5. On the frame 1 below the second limiting plate 11, there are three second assembly grooves 12. A second screw rod 13 is movably installed in the second assembly groove 12 at the middle position. The second screw rod 13 extends to the outside of the frame 1. A second handle 14 is arranged on the second screw rod 13 extending to the outside of the frame 1. The second screw rod 13 is in threaded connection with the second limiting plate 11. Second guide rods 15 are fixedly installed in the second assembly grooves 12 on both sides of the second screw rod 13. The second guide rods 15 are slidably connected with the second limiting plate 11. During operation, by rotating the second handle 14, the second screw rod 13 is driven to rotate. When the second screw rod 13 rotates, the second limiting plate 11 is driven to slide along the axial direction of the second guide rod 15.

[0027] One side of the turning plate is symmetrically and movably hinged with turning hydraulic cylinders 2 through first connecting pieces 18. On the corresponding frame 1 of the turning hydraulic cylinders 2, there is a relief groove 16. The relief groove 16 is a rectangular groove. The purpose of such a setting is: through the relief groove 16, a relief is formed for the turning hydraulic cylinders 2, facilitating the turning operation of the turning hydraulic cylinders 2 in cooperation with the turning plate.

[0028] On the inner bottom surface of the relief groove 16, there is a relief gap 17. The purpose of such a setting is: through the relief gap 17, it is convenient to form a relief for the pipelines on the turning hydraulic cylinders 2. The turning hydraulic cylinders 2 are externally connected to a hydraulic station through pipelines.

[0029] A second connecting piece 19 is arranged in the relief groove 16. The second connecting piece 19 is movably hinged with the turning hydraulic cylinders 2. The first connecting piece 18 and the second connecting piece 19 include connecting ear plates and a rotating shaft. The connecting ear plates are symmetrically and fixedly installed on the frame 1. A rotating shaft is arranged between the connecting ear plates. The rotating shaft of the first connecting piece 18 is fixedly connected with the piston rod of the turning hydraulic cylinders 2. The rotating shaft of the second connecting piece 19 is fixedly connected with the cylinder block of the turning hydraulic cylinders 2. During operation, when the piston rod of the turning hydraulic cylinders 2 extends, the turning plate can be pushed to perform a turning action.

[0030] On both ends of the corresponding frame 1 of the turning plate, there are symmetrically arranged cushion blocks 20 respectively. The purpose of such a setting is: through the cushion blocks 20, the turning plate is elevated, so that the turning plate can be effectively kept in a stable state by the support of the cushion blocks 20 after turning.

[0031] When the turning mechanism for the pump head cylinder block of the fracturing truck is in use, first, the workpiece to be assembled is placed on the turning plate. Then, the operator manually rotates the first handle 9 and the second handle 14 in sequence and orderly, so that the first limiting plate 6 and the second limiting plate 11 are sequentially in contact connection with the workpiece, thereby realizing the limiting of the workpiece on the turning plate through the first limiting plate 6 and the second limiting plate 11. At this time, the operator starts the processing or assembly operation on the workpiece.

[0032] When it is necessary to turn the workpiece by 90°, start the turning hydraulic cylinder 2. The piston rod of the turning hydraulic cylinder 2 extends. Under the cooperation of the first connecting piece 18, the second connecting piece 19, and the frame 1, the piston rod of the turning hydraulic cylinder 2 pushes the turning plate to rotate 90° around the axis of the assembly short shaft 4. During the turning process of the turning plate, the workpiece is driven to rotate synchronously until the turning plate contacts and connects with the cushion block 20. At this time, stop the piston rod of the turning hydraulic cylinder 2, thereby completing the turning operation of the workpiece, and then the machining or assembly operation of the workpiece can be continued.

[0033] When the turning mechanism for the pump head cylinder block of the fracturing truck is in use, by placing the workpiece (pump head cylinder block 21 of the fracturing truck) on the turning plate and limiting it through the cooperation of the first limiting component and the second limiting component, slippage during its turning is prevented, thereby avoiding the problem that the workpiece accidentally slips off the turning plate. By extending or retracting the piston rod of the turning hydraulic cylinder 2, the turning plate is realized to turn 0 - 90° around the axial direction of the assembly short column, thereby realizing the 0 - 90° turning of the workpiece on the turning plate. The turning mechanism for the pump head cylinder block of the fracturing truck has a simple structure and is convenient to use, solving the problems of high labor intensity and low turning efficiency in the existing manual-assisted turning operation, and the problem that it is easy to injure the staff and pose potential safety hazards to personal safety during the turning process.
