All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Embodiment 1

[0025] See also Figure 1-Figure 7 The utility model provides a technical solution: a skid-mounted reciprocating pump hidden lifting structure, the skid-mounted reciprocating pump hidden lifting structure comprises: a base 1 and a connecting ring 4, a skid-mounted pump body 2 is installed on the top of the base 1, a frame 3 is installed around the top of the base 1, and the connecting ring 4 penetrates and connects to the through hole of the frame 3;

[0026] A driving motor 5 is installed on one side of the frame 3 through the outer shell, and a transmission shaft 6 is connected between the output end of the driving motor 5 and the groove of the frame 3 through a coupling, and a bevel gear set 7 is connected to the bottom of the transmission shaft 6, and a screw rod 8 penetrating the frame 3 is connected to the bottom of the bevel gear set 7. The bottom of the screw rod 8 is connected to a connecting frame 9 through a bearing, and a screw sleeve 10 is sleeved on the outer side of the screw rod 8. Connecting rods 11 are installed on both sides of the screw sleeve 10, and a connecting block 12 is installed on the top of the connecting rod 11. The connecting block 12 is connected to the bottom of the connecting ring 4, and two groups of screw rods 8 are installed symmetrically about the center line of the transmission shaft 6.

[0027] Embodiment 2

[0028] On the basis of the first embodiment, in order to achieve the function of hiding the connecting ring 4, the driving motor 5 can be started, and the driving motor 5 will drive the transmission shaft 6 at the output end to rotate. A bevel gear set 7 is installed at the bottom of the transmission shaft 6. The bevel gear set 7 is formed by two mutually meshing bevel gears meshing and connecting. One bevel gear is connected to the transmission shaft 6, and the other bevel gear is connected to the screw rod 8. The rotation of the transmission shaft 6 will drive the screw rod 8 to rotate through the bevel gear set 7. The bottom of the screw rod 8 is connected to the connecting frame 9 through a bearing, and the connecting frame 9 is installed in the middle of the frame 3. The stability of the entire screw rod 8 can be ensured by the connecting frame 9. A screw sleeve 10 is sleeved on the outside of the screw rod 8. Connecting rods 11 are installed on both sides of the screw sleeve 10. A connecting block 12 that penetrates the frame 3 is installed on the top of the connecting rod 11. The connecting block 12 is guided by the through hole of the frame 3 and can only slide up and down along the frame 3. At this time, the rotation of the screw rod 8 will drive the connecting block 12 and the connecting ring 4 to slide downward through the cooperation of the screw sleeve 10 and the connecting rod 11, so that the connecting ring 4 shrinks into the groove of the frame 3. At this time, the connecting ring 4 can be hidden and stored;

[0029] When it is necessary to use the connecting ring 4 for lifting, the driving motor 5 can drive the transmission shaft 6 to rotate in the opposite direction. The reverse rotation of the transmission shaft 6 will drive the screw 8 to rotate in the opposite direction through the cooperation of the bevel gear set 7, so that the screw sleeve 10 drives the connecting ring 4 to move out of the groove at the top of the frame 3 through the connecting rod 11 and the connecting block 12. At this time, the wire rope can be hung in the connecting ring 4, so as to facilitate the lifting of the skid-mounted pump body 2.

[0030] A first snap ring 13 is sleeved on the outer side of the connecting ring 4, and one side of the first snap ring 13 is connected to a second snap ring 14 through a rotating shaft, an arc rod 15 is connected between the two groups of first snap rings 13 and second snap rings 14, and the inner walls of the first snap ring 13 and the second snap ring 14 are both equipped with protrusions 16, and one side of the second snap ring 14 is equipped with a fixing block 17, and one side of the fixing block 17 is connected with a screw rod 18, and one side of the screw rod 18 is connected with a top block 19 that penetrates the fixing block 17 through a bearing, and one side of the top block 19 is provided with a wedge block 20 through an inclined surface, and the wedge block 20 is installed on one side of the first snap ring 13.

[0031] Embodiment 3

[0032] On the basis of the second embodiment, in order to prevent the wire rope from sliding along the connecting ring 4, the screw 18 can be rotated according to the size of the wire rope. Since the screw 18 is connected to the top block 19 through the bearing, and the screw 18 and the fixed block 17 are threadedly connected, the rotating screw 18 will drive the top block 19 to move, so that the top block 19 does not squeeze the wedge block 20 on one side. Since the wedge block 20 is installed on one side of the first clamping ring 13, and the top block 19 is connected to one side of the second clamping ring 14 through the fixed block 17 and the screw 18, the first clamping ring 13 and the second clamping ring 14 will be loose at this time, and then the second clamping ring 14 will be rotated by the rotating shaft. Rotate to one side so that the protrusions 16 on the inner walls of the first clamp ring 13 and the second clamp ring 14 do not squeeze the connecting ring 4. At this time, the first clamp ring 13 and the second clamp ring 14 can slide along the connecting ring 4, and drive another set of the first clamp ring 13 and the second clamp ring 14 to slide to one side of the wire rope through the arc rod 15. Similarly, move the first clamp ring 13 and the second clamp ring 14 on the other side of the wire rope to one side of the rope. The wire rope can be limited by the first clamp ring 13 and the second clamp ring 14, thereby preventing the wire rope from sliding along the inner wall of the connecting ring 4, making the entire wire rope more stable when lifting the skid-mounted pump body 2;

[0033] When it is necessary to limit and fix the first clamping ring 13 and the second clamping ring 14, the screw rod 18 is rotated in the opposite direction so that the screw rod 18 drives the top block 19 to move in the direction of the wedge block 20. Since the ends of the top block 19 and the wedge block 20 that are close to each other are both inclined structures, the movement of the top block 19 in the direction of the wedge block 20 will squeeze the wedge block 20. When the wedge block 20 is squeezed, it will drive the second clamping ring 14 to move, so that the second clamping ring 14 and the first clamping ring 13 move close to each other, and the protrusions 16 on the inner walls of the first clamping ring 13 and the second clamping ring 14 squeeze the connecting ring 4, so that the first clamping ring 13 and the second clamping ring 14 can be limited. Due to the limiting effect of the first clamping ring 13 and the second clamping ring 14, the wire rope is not easy to slide.

[0034] In actual use, when the skid-mounted reciprocating pump hidden lifting structure is in use, the wire rope can be passed through the connecting ring 4 and fixed, and the wire rope can be connected to the other three groups of connecting rings 4 on the top of the frame 3 according to the same steps. The other end of the wire rope is connected to the crane, and the skid-mounted pump body 2 can be lifted by the crane. After the skid-mounted pump body 2 is lifted to a suitable position, it is placed in a stable position through the base 1 at the bottom of the skid-mounted reciprocating pump body 2, so that the entire skid-mounted reciprocating pump can work normally.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
