It should be noted that, the vibration absorbing portion 2 drives the vibration absorbing portion 2 and the pump body of the portable pump to move with the deformation amount by extruding the flexible concave base 1, which is actually required to be achieved, when the pump body of the portable pump vibrates, the pump body and the vibration absorbing portion 2 are relatively static, so as to achieve synchronous operation, eliminate resonance between the vibration absorbing portion 2 and the pump body of the portable pump, and the design needs to be comprehensively considered by combining the elasticity of the material selected by the vibration absorbing portion 2, the elasticity of the material of the flexible concave base 1 and the magnitude of the force born by the vibration absorbing portion 2.
At present, when the portable pump on the existing scaffold plane is used, in order to ensure the stability reduction of the scaffold, a shock pad made of rubber, silica gel or other elastic materials is generally installed between the pump body and the scaffold, the shock pad is placed on a supporting point between the pump body and the scaffold to absorb and isolate vibration, so that equipment is protected, personnel safety is guaranteed, the structural integrity of the scaffold is maintained, but when the scaffold plane is used in a narrow space, the narrow space limits the movable range of an operator, the stable foundation for placing the equipment is also reduced, under the working condition, in order to ensure the safety of the portable pump when the portable pump is used on the scaffold plane, the requirement on the anti-vibration sliding performance of the portable pump is required to be higher, and when the pump body is in operation, the shock pad is placed on the supporting point between the pump body and the scaffold, vibration generated by the pump body possibly generates resonance with the shock pad, and the existence of the shock pad can amplify the vibration instead of reducing the vibration, so that horizontal sliding between the pump body and the scaffold is caused, and the safety risk is increased.
In order to solve the above problem, it is necessary to ensure that the damping portion 2 must maintain the stable posture of the pump body of the portable pump in a certain deformation interval, so as to reduce the instantaneous inclination angle of the pump body in the vibration process, therefore in this embodiment, by connecting the outer convex portion of the outer convex supporting portion 3 with the pump body of the portable pump, the outer convex supporting portion 3 far away from the outer convex portion is connected with the inner concave portion of the flexible inner concave base 1 through the damping portion 2, and then the two ends of the damping portion 2 are respectively connected with the flexible inner concave base 1 and the outer convex supporting portion 3, so that when the pump body of the portable pump is used on a scaffold, the vibration of the pump body of the portable pump is transferred to the damping portion 2 through the outer convex supporting portion 3, and the damping portion 2 is attached to the flexible inner concave base 1, so as to squeeze the flexible inner concave base 1 to make the damping portion 2 and the pump body of the portable pump move by the same deformation amount, and finally eliminate the resonance between the damping portion 2 and the pump body of the portable pump, thereby guaranteeing the posture balance of the portable pump to avoid increasing local load due to the inclination of one side, so as to weaken the side damping effect, and make each damping foot uniformly stressed, when the scaffold is used, the problem of the pump body of the portable pump is solved, and the problem of vibration generated by itself is prevented from slipping horizontally between the pump body and the pump body is avoided.
Because the portable pump is used in a narrow space of a scaffold plane, and the ground is often uneven on the scaffold, in order to reduce shaking of the portable pump and avoid overturning of the pump body in the narrow space, in one embodiment, the trapezoid structure of the flexible concave base 1 is arranged on the bottom surface of the trapezoid structure, the top surface of the trapezoid structure is attached to the scaffold, the trapezoid structure can better disperse the pressure born by the pump body, so that the pressure distribution is more uniform, the overturning risk caused by overlarge local pressure is reduced, the gravity center of the pump is lower through the design of the trapezoid structure, the stability can be improved, the trapezoid structure is combined with the flexible concave base 1, the stability of the pump is improved, the overall structural strength of the pump is also enhanced, in addition, a plurality of rectangular bulges 11 are arranged on the top surface of the trapezoid structure, the rectangular bulges 11 are rectangular frames, the criss-cross distribution of the rectangular bulges 11 can strengthen the internal structure of the base, the rectangular bulges 11 are dispersed vertically and horizontally, and alternately, and the rectangular bulges 11 are dispersed at first, and then the rectangular bulges 11 are dispersed, so that the pressure can be impacted on the ground, and the shock can be reduced in the pump body, and the shock is acted on the pump; secondly, the design of the rectangular bulge 11 can enable the air circulation between the pump body and the ground to be smoother, thereby being beneficial to heat dissipation, reducing the temperature possibly generated by the pump in the long-time operation process, and simultaneously being beneficial to improving the anti-slip effect by moderately increasing the contact area between the rectangular bulge 11 and the ground.
Because when the portable pump is used, if the gesture balance of the portable pump is wanted, avoid increasing local load because of one side slope, be convenient for weaken this side shock attenuation effect, just need ensure that shock absorber 2 and the pump body of portable pump move with the deflection, still need flexible indent base 1, shock absorber 2 and the center of evagination supporting part 3 three are located same straight line, so just can ensure the balance, but in fact, in this motion process, because of vibration's reason, the back for a long time, the skew takes place between shock absorber 2 and the evagination supporting part 3, result in shock absorber 2 and the center of evagination supporting part 3 not being located same straight line, just can't guarantee at this moment that shock absorber 2 and the pump body of portable pump move with the deflection, consequently, in order to solve this problem, evagination supporting part 3 includes evagination supporting seat 31 and bracing piece 32, set up spacing groove 33 on the evagination supporting seat 31 of keeping away from the evagination part, bracing piece 32 runs through evagination supporting seat 31 perpendicularly to spacing groove 33 in, the one end and spacing groove 33 of shock absorber 2 cooperatees, the other end and flexible indent base 1's interior recess bottom laminating, the reason that the shock absorber 2 and the vibration absorber 2 can's the bottom is located same straight line with the bottom of the recess 3, can not guarantee at the bottom of the shock absorber 2 and the bottom of the vibration absorber 2 is located at the same bottom of the recess 2 and the bottom of the vibration absorber 2 is not located at the bottom of the same straight line of the bottom of the recess of the vibration supporting part of the vibration absorber 3.
In addition to the above, in order to further enable the damper portion 2 and the pump body of the portable pump to always keep the same deformation amount to move, in an embodiment, the damper portion 2 includes a conical spring 21 and a spacer 22 sleeved on a supporting rod 32 in a limiting groove 33, the top of the conical spring 21 is attached to the spacer 22, the diameter of the spacer 22 is greater than the diameter of the top surface of the conical spring 21 by 1-2 mm, the diameter of the spacer 22 is greater than the diameter of the top surface of the conical spring 21 by 1mm, 1.5mm or 2mm, the limitation of 1-2 mm is to ensure that the damper portion 2 and the pump body of the portable pump are convenient to operate in design, in fact, only a part of the diameter of the spacer 22 is greater than the diameter of the top surface of the conical spring 21 is required, because the diameter of the spacer 22 is greater than a part of the diameter of the top surface of the conical spring 21, when the conical spring 21 is slightly moved due to careless occurrence of the external factors, the position of the conical spring 21 is also ensured to be unchanged, namely the damper portion 2 and the pump body of the same deformation amount as the portable pump can still be moved; the bottom of the conical spring 21 is attached to the bottom of the inner groove of the flexible concave base 1, the limit groove 33 is of a conical structure, the conical structure of the limit groove 33 is matched with the conical spring 21, the bevel edge of the conical structure of the conical spring 21 is the same as the bevel edge angle of the flexible concave base 1, and as seen in fig. 1, the conical spring 21 is the top part above, the bottom part below, the top part of the flexible concave base 1 is the bottom part above, the bevel edge of the conical structure of the conical spring 21 is the same as the bevel edge angle of the flexible concave base 1, which is equivalent to the fact that the flexible concave base 1 is placed in an inverted trapezoid shape, the bevel edge angles of the inverted trapezoid and the conical spring 21 are the same, meaning that when the spring is compressed, the bevel edge can better guide and disperse force, so that the spring is more efficient in the shock absorption process, and the same bevel angle of the inverted trapezoid and the conical spring 21 helps to reduce resonance phenomena of the system at specific frequencies, since this design is better able to absorb and disperse the vibration energy at these frequencies, thereby eliminating resonance between the shock absorbing portion 2 and the body of the portable pump.
Finally, the vibration generated by the pump body during operation is transferred to the spring through the outer convex supporting seat 31 and finally acts on the flexible concave base 1, so that the stability of the connection between the outer convex supporting seat 31 and the flexible concave base 1 is required to be ensured in the process, and in this way, in one embodiment, the diameter of the outer convex supporting seat 31 far from the outer convex part is larger than that of the outer convex supporting seat 31 of the outer convex part, a clamping groove 4 is arranged in an inner groove of the flexible concave base 1, the outer convex supporting seat 31 far from the outer convex part is clamped in the clamping groove 4, the diameter of the outer convex supporting seat 31 far from the outer convex part is larger than that of the inner groove of the flexible concave base 1, the diameter of the bottom surface of the conical spring 21 is smaller than that of the inner groove of the flexible concave base 1, and the structure is specially designed as shown in the combination of figures 4,5 and 6, the connecting part between the outer convex supporting seat 31 and the flexible concave base 1 and the diameter of the bottom surface of the conical spring 21 are specially limited, the outer convex supporting seat 31 is clamped in the inner groove of the flexible concave base 1 through the clamping groove 4, when the pump body works to generate vibration, the conical spring 21 is driven by the pump body to synchronously move, meanwhile, the outer convex supporting seat 31 moves in the clamping groove 4, in the process, the same deformation of the shock absorbing part 2 and the pump body of the portable pump can be ensured, the outer convex supporting seat 31 and the flexible concave base 1 can not be loosened, in addition, the outer surface of the part of the outer convex supporting seat 31 positioned in the clamping groove 4 is smooth, when the part of the outer convex supporting seat 31 positioned in the clamping groove 4 is completely jointed with the clamping groove 4, the outer convex supporting seat 31 can move in the clamping groove 4, because the flexible concave base 1 can deform, the distance of the deformation compensation movement can be used, and as such, the shock absorbing part 2 and the pump body of the portable pump move by the same deformation amount, and the reaction force becomes large after the conical spring 21 is compressed, because of the distance of the deformation compensation movement of the flexible concave base 1.
The present invention is not limited in any way by the above-described preferred embodiments, but is not limited to the above-described preferred embodiments, and any person skilled in the art will appreciate that the present invention can be embodied in the form of a program for carrying out the method of the present invention, while the above disclosure is directed to equivalent embodiments capable of being modified or altered in some ways, it is apparent that any modifications, equivalent variations and alterations made to the above embodiments according to the technical principles of the present invention fall within the scope of the present invention.
