Specific embodiments

[0030] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] The present invention provides a multi-dimensional vibration damping base for a drilling pump, as Figure 1As shown, it includes a base assembly 3. The base assembly 3 is slidably connected with a multi-dimensional vibration damping assembly 1. The multi-dimensional vibration damping assembly 1 is fixedly connected with a support and limit assembly 2, and the other end of the support and limit assembly 2 is fixedly connected with the base assembly 3. As Figure 2 shown, the multi-dimensional vibration damping assembly 1 includes a sliding vibration damping seat 101. The upper end surface of the sliding vibration damping seat 101 is fixedly connected with a floating vibration damping seat 104, and the lower end surface of the sliding vibration damping seat 101 is slidably connected with the base assembly 3. As Figure 3 shown, the cross-section of the sliding vibration damping seat 101 is in a "U" shape. The sliding vibration damping seat 101 is fixedly connected by two parallel rib plates and a piston mounting plate 103. A slider 108 is fixedly connected to the bottom of the rib plates of the sliding vibration damping seat 101. Lower connecting rod mounting seats 116 and lower spring mounting seats 117 are symmetrically arranged on the two parallel rib plates of the sliding vibration damping seat 101. The lower connecting rod mounting seat 116 is connected with a lower connecting rod 111 through a bolt 113. As Figure 4 shown, a damping spring 107 and a floating damper 112 are arranged in the lower spring mounting seat 117. As Figure 5 shown, the cross-section of the piston mounting plate 103 is in a "U" shape. A number of piston mounting seats 102 are symmetrically arranged on the plate surface of the piston mounting plate 103. The number of piston mounting seats 102 are jointly fixedly connected with a piston assembly. Polyurethane gaskets are arranged between the number of piston mounting seats 102 and the piston assembly. The polyurethane gaskets have good load-bearing deformation ability and can buffer or even isolate the vibration generated during the operation of the motor from being transmitted to the base 301. As Figure 6 shown, the floating vibration damping seat 104 includes a crankshaft mounting plate 105 with a cross-section in a "U" shape. A number of crankshaft mounting seats 106 are symmetrically arranged on the plate surface of the crankshaft mounting plate 105. The number of crankshaft mounting seats 106 are jointly fixedly connected with a crankshaft assembly. Polyurethane gaskets are arranged between the number of crankshaft mounting seats 106 and the crankshaft assembly. The polyurethane gaskets have good load-bearing deformation ability and can buffer or even isolate the vibration generated during the operation of the motor from being transmitted to the base 301. As Figure 7 shown, upper connecting rod mounting seats 114 and upper spring mounting seats 115 are symmetrically arranged at the bottom of the crankshaft mounting plate 105. As Figure 8As shown in the figure, the upper connecting rod mounting seat 114 is connected to the upper connecting rod 109 by bolts 113. The upper connecting rod 109 is hinged to the lower connecting rod 111. The two connecting rods can rotate freely around the connecting rod mounting seat, playing a role in longitudinally supporting the floating shock absorber seat 104, ensuring that the floating shock absorber seat 104 can longitudinally slide together with the sliding shock absorber seat 101 without relative sliding between them. The upper spring mounting seat 115 is fixedly connected to the top of the floating damper 112 and the shock absorber spring 107. The floating shock absorber seat 104 is floatingly mounted on the sliding shock absorber seat 101 through the floating damper 112 and the shock absorber spring 107. The floating damper 112 plays a supporting role for the floating shock absorber seat 104, and the shock absorber spring 107 filters and cancels the lateral vibration and swing on the floating shock absorber seat 104; there is a torsion crossbeam 110 between the two parallel sections of the crankshaft mounting plate 105. The two arms of the torsion crossbeam 110 are welded by two cross-shaped rib plates, and the two arms form a certain angle. A through hole is opened in the middle of the torsion crossbeam 110, and a support and limit assembly 2 is passed through the through hole. As Figure 9 shown, the support and limit assembly 2 includes a support and limit rod 202. Both ends of the support and limit rod 202 are fixedly connected with limit shock absorber springs 204. Longitudinal dampers 201 are arranged in both of the two limit shock absorber springs 204. Ring-shaped mounting seats are respectively arranged on the corresponding side walls of the base 301 and the sliding shock absorber seat 101. A sliding damper 201 and a limit shock absorber spring 204 are arranged in the ring-shaped mounting seats. The support and limit rod 202 is fixedly connected with the sliding dampers 201 and the limit shock absorber springs 204 in the two ring-shaped mounting seats and passes through the through hole in the middle of the torsion crossbeam 110. A polyurethane shock absorber ring 203 is arranged in the through hole. The polyurethane shock absorber ring 203 can filter and cancel the axial vibration and pulsation received by the support and limit rod 202. At the same time, the support and limit rod 202 connects the base 301 and the sliding shock absorber seat 101, and can filter and cancel the longitudinal vibration and displacement generated by the sliding shock absorber seat 101. As Figure 10 shown, the base assembly 3 includes a base 301 in a "rectangular" frame. The base 301 serves as a carrier for all components. Threaded holes are arranged around the bottom installation edge of the base 301, and the base 301 is fixed to the ground by bolts. Two symmetrical sliding grooves 302 are arranged on the two parallel sections of the base 301. The size of the slider 108 matches that of the sliding groove 302, and the slider 108 slides in the sliding groove 302. Sliding groove support platforms 303 are arranged on both sides of the sliding groove 302. As Figure 11 shown, a number of rolling limit grooves 304 are evenly arranged in the two sliding grooves 302. Rubber balls 308 are arranged in a number of rolling limit grooves 304. The rubber balls 308 are made of vulcanized rubber, with high load-bearing capacity and anti-vibration performance. The rubber balls 308 are slidably connected to the slider 108. The bottom of the slider 108 contacts and presses the rubber balls 308. At this time, the whole sliding shock absorber seat 101 is supported by the rubber balls 308. As Figure 12As shown, the left and right ends of the base 301 are welded into an I-shaped load-bearing platform through a rib plate 307, and a motor mounting plate 305 is provided at either end of the base 301. The motor mounting plate 305 is in contact with the slide support platform 303, and the motor mounting plate 305 is symmetrically provided with a plurality of motor mounting seats 306, and the plurality of motor mounting seats 306 are fixedly connected to the motor together. Polyurethane gaskets are provided between the plurality of motor mounting seats 306 and the motor, and the polyurethane gaskets have good load-bearing deformation capacity, and can buffer or even isolate the vibration generated during the operation of the motor from being transmitted to the base 301.

[0032] The present invention provides a multi-dimensional vibration reduction base for a drilling pump, and its working principle is as follows: when the motor is working, the motor drives the crankshaft assembly to rotate, and the crankshaft drives the piston to reciprocate through the connecting rod. At this time, the single-axis rotation of the motor itself is in a dynamic equilibrium state, and the vibration generated is small. The polyurethane gasket on the motor mounting seat 306 can filter the vibration generated by the motor well by its own extremely strong load-bearing deformation characteristics, and no additional vibration will be generated for the base 301. Due to the special structure of the crankshaft itself and the existence of processing and assembly errors, more complex vibrations will be generated when rotating at high speed, and jumping will occur in the vertical direction, and lateral vibration and swing will also be generated, which will transmit a large amount of additional vibration to the base 301. At this time, the polyurethane gasket under the crankshaft assembly can filter part of the vibration, and the remaining vertical and lateral vibrations are filtered and offset by the vertical displacement generated by the floating vibration reduction seat 104. The piston reciprocates and generates large vibrations in the longitudinal direction. These additional longitudinal vibrations will be transmitted to the sliding vibration damping seat 101 and drive the sliding vibration damping seat 101 to produce periodic displacement in the longitudinal direction. The longitudinal vibrations transmitted to the base can be greatly eliminated by filtering and offsetting the supporting limit rod 202 and the sliding dampers 201 on both sides of the rod and the limit vibration damping springs 204. This can minimize the harmful vibrations generated by the water injection pump, extend the service life of the pump components, and reduce the working noise.
