[0021] like Figure 1-5As shown, a multifunctional stator transfer trolley for hydraulic testing of PCP screw pumps comprises an electric transfer trolley 1, a lifting platform 3 arranged on the electric transfer trolley 1 and a stator assembly clamp 5 slidingly arranged on the lifting platform 3. The electric transfer trolley 1 is a vehicle capable of movement. There are methods for realizing this structure in the prior art. Tracks can be set, and the forward or backward movement can be controlled by the forward and reverse rotation of the motor on the track. The specific structure will not be repeated here; the stator assembly clamp 5 comprises a clamp 1 and a clamp 2 with the same structure and relatively arranged. The clamp 1 and the clamp 2 can be set to different specifications to meet the clamping and fixing requirements of stators of different diameters. The clamp 1 and the clamp 2 both comprise a stator clamp base 51 and a clamp cooperating with the stator clamp base 51. The clamp comprises an inverted U-shaped stator. Sub-clamp support 52, the stator clamp support 52 is provided with movable grooves on both sides, a clamp hook 56 is provided in the movable groove, and a movable bolt is provided between the clamp hook 56 and the movable groove, the top of the two clamp hooks 56 is provided with a stator clamp upper pressure plate 53 with a protrusion in the center of the bottom surface and both ends are placed in the movable groove, the stator clamp upper pressure plate 53 is provided with a stator clamp adjusting screw 54 and the stator clamp adjusting screw 54 passes through one end of the stator clamp support 52 and is provided with a handle 55, both sides of the stator clamp base 51 are provided with flanges that cooperate with the clamp hook 56, the middle part of the stator clamp base 51 is provided with a V-shaped placing table, and the stator clamp support 52 is provided with a threaded hole that cooperates with the stator clamp adjusting screw 54.

[0022] like Figure 3 As shown, an electric worm gear lifting system 2 is provided between the electric transfer vehicle 1 and the lifting platform 3. The electric worm gear lifting system 2 includes worm gear lifts 22 respectively provided at the four corner ends of the electric transfer vehicle 1. A cross-steering device 25 is provided between the two worm gear lifts 22 located on the same side. A connecting shaft 24 is provided between the cross-steering devices 25 on both sides. A worm gear lift motor 21 is connected to any one of the worm gear lifts 22. A lift connection flange 26 is provided between the lifting platform 3 and the electric worm gear lifting system 2. The electric worm gear lift 22 is fixed to the electric transfer vehicle 1, and the worm gear lift motor 21 controls the worm gear lift 22 to rise or fall; the lifting platform 3 is connected to the lift connection flange 26 of the worm gear lift 22 system, and the lifting platform 3 is raised or lowered.

[0023] like Figure 4As shown, an electric lead screw slide 4 is provided between the lifting table 3 and the stator assembly fixture 5. The electric lead screw slide 4 includes a lead screw slide base 43 connected to the lifting table 3. The lead screw slide base 43 is provided with a lead screw adjustment motor 41, a coupling 23, and a lead screw 45 connected in sequence. Slide rails 44 are provided on both sides of the lead screw 45. Slide rails 44 are provided on the slide rails 44. A slide connecting plate 46 is provided between the slide and the stator assembly fixture 5. The electric lead screw slide 4 is fixed to the lifting table 3 by bolts, and the stator assembly fixture 5 is mounted on the slide connecting plate 46 of the electric lead screw slide 4, which can slide left and right.

[0024] When testing and installing the PCP pump, the stator needs to be clamped with the stator combination clamp 5. First, place the stator on the stator clamp base 51, and then place the stator clamp support 52 on the upper part of the stator. The stator clamp upper pressure plate 53 contacts the stator, and the clamp hook 56 hooks the flange on the edge of the clamp base. Turn the handle 55, adjust the stator clamp adjustment screw 54 to press the stator clamp upper pressure plate 53 downward to clamp the stator. When both ends of the stator are clamped with the stator combination clamp 5, start the electric transfer vehicle 1 to move the stator to the vicinity of the rotor, and observe whether the height and left and right positions of the stator mouth are consistent with the rotor. If not, adjust the stator position. The up and down adjustments are adjusted by the worm gear lift motor 21, and the left and right positions are adjusted by adjusting the electric screw slide 4. Insert the rotor into the stator, start the machine to continue rotating the rotor, and move the stator trolley forward until the rotor is completely in the stator.

[0025] In this process, the stator assembly clamp 5 is required to not only clamp the stator, but also perform fine adjustments up and down and left and right to allow the rotor to enter the stator gap. This requires adjusting the worm gear lift 22 system to drive the lifting table 3 and adjusting the electric screw slide 4 to drive the stator assembly clamp 5 to move.

[0026] After the test is completed, when the stator and rotor need to be separated, reverse the rotor and drive the electric transfer trolley to the opposite position until they are separated.

[0027] Because the stator assembly clamp 5 can be adjusted to move up and down and left and right to drive the movement of the entire stator, the stator center can be movable and controllable, and a set of clamps can be used to complete the assembly of rotors and stators of different models, thereby improving the speed of hydraulic testing of the pump efficiency of the PCP screw pump. In addition, the stator assembly clamp 5 is simple and quick to operate and can quickly clamp the stator, saving time and effort when moving the stator and improving safety.
