The 1 st to 3 rd points of the synergistic effect in the scheme are as follows: if only the 2 nd and 3 nd structures are adopted, but the spring-form limiting assembly at the 1 st point is not adopted, the rigid impact of the pump pipe and the limiting assembly is large, and the impact energy is transmitted to the steel pipe frame through the swinging block and the vertical connecting plate, so that the pump pipe cannot be effectively prevented from being separated from the steel pipe frame; if the structures 1 and 3 are adopted and the structure of the point 2 is not adopted, the pump pipe cannot be effectively constrained, so that the pump pipe cannot freely sway in the limiting hole (301), the limiting assembly cannot absorb energy, and the pump pipe cannot be effectively prevented from being separated from the steel pipe frame; if only adopt the structure of 1 st and 2, though the pump line can rock by the restraint in spacing hole (301), but the energy that the pump line rocked is great, not only leads to the pressure spring inefficacy among the spacing subassembly like this easily, strikes the swing piece easily moreover to let swing piece and vertical connecting plate rigidity impact, also can't prevent effectively like this that the pump line breaks away from the steel-pipe frame. And the 1 st to 3 rd parts are matched, the pump pipe can be reset towards the axle center of the limiting hole after being shaken in the limiting hole, and the swinging block can also be automatically reset under the action of springs on two sides, so that the pump pipe is effectively prevented from being separated from the steel pipe frame, and meanwhile, the pump pipe can be automatically reset after being vibrated, and further, the scheme forms an interaction and cooperation unified whole which can not be divided.

In the scheme, the initial tension value and the deformation value set by the two tension springs 8 are equal, so that the swinging block 3 can be urged to be in a static state relative to the plate surface of the vertical supporting plate 5 under the tension action of the tension springs 8.
As shown in fig. 1 and 2, a limiting hole 301 vertically penetrating up and down is formed in the center of the limiting portion 32, and the aperture of the limiting hole 301 is larger than the outer diameter of the pump tube 1, so that the pump tube can rock in the limiting hole 301. As shown in fig. 2 to 4, a set of limiting grooves 302 are uniformly formed on the upper end surface of the limiting portion 32 along the circumferential direction, the limiting grooves 302 are formed along the radial direction of the limiting hole 301, the number of the limiting grooves 302 is 3 to 8, and the number of the limiting grooves 302 in this case is 3. The inner ends of the limiting grooves 302 are communicated with the limiting holes 301, and a limiting component is arranged in each limiting groove 302.
The limiting assembly comprises a cast iron ball 9, a pressure spring 10 and an adjusting bolt 11, wherein the cast iron ball 9 and the pressure spring 10 are both arranged in a limiting groove 302, the pressure spring 10 is positioned between the cast iron ball 9 and the adjusting bolt 11, and the cast iron ball 9 is in rolling fit with the groove wall of the limiting groove 302, so that the cast iron ball 9 can be ensured to linearly move along the length direction of the limiting groove 302. The adjusting bolt 11 is in threaded connection with the limiting part 32, and the tail part of the adjusting bolt 11 is abutted against the end part of the pressure spring 10. The pressure spring 10 can be pre-tightened through the bolt 11, so that on one hand, installation errors are eliminated, and on the other hand, the action points of the three cast iron balls 9 can be kept at the center of the limiting hole 301 through adjusting the bolt 11 in the using process.
As shown in fig. 3 and 4, the upper end surface of the limiting portion 32, on which the limiting groove 302 is formed, is fixedly connected with a cover plate 12, and the cover plate 12 prevents the cast iron ball 9 from falling out of the limiting groove 302. In this case, a central hole 121 for passing a pump pipe is formed in the center of the cover plate 12, and a limit ring 122 is protruded from the bottom surface of the cover plate 12 facing the limit groove 302, and the axis of the limit ring 122 is collinear with the axis of the central hole 121. The position of the bottom of the limiting ring 121 corresponding to the cast iron ball 9 is provided with a limiting notch 123, the inner end of the limiting notch 123 is small, the outer end is large, and the width of the narrowest part is smaller than the diameter of the cast iron ball 9. The limiting ring 122 is designed to allow a portion of the ball of the cast iron ball 9 to extend into the central hole, but not allow the cast iron ball 9 to fall out of the limiting groove 302.
The working principle of the scheme is as follows: the vertical support plate 5 is fixed on the steel pipe frame 13 through the connecting buckle 6, and after the swinging block 3 is rotatably connected with the vertical support plate 5 through the rotating part 31, the swinging block 3 can only swing on the vertical support plate 5. Under the tensile force of the tension spring 8 between the limiting part 32 of the swing block 3 and the vertical support plate 5, the swing block 3 in the initial state is kept in a static state relative to the vertical support plate 5, that is, the swing block 3 without external force is static and fixed on the vertical support plate 5. When the pump pipe is used, the pump pipe 1 vertically penetrates through the limiting hole 301 in the limiting part 32 from top to bottom without manual adjustment, and the pressure spring 10 extrudes the cast iron ball 9 and enables the cast iron ball 9 to tightly support the pump pipe 1. In the scheme, the number of the limiting grooves 302 arranged on the limiting part 32 is three, the three limiting grooves 302 are uniformly distributed along the circumferential direction of the limiting hole 301, and three pressure springs 10 and three cast iron balls 9 are correspondingly arranged in the three limiting grooves 302 one by one. The three cast iron balls 9 complete the abutting action of the pump pipe 1 from the same plane in three different directions.
In the scheme, the cast iron ball 9 is adopted, and on one hand, the existing pump pipe 1 is generally made of cast iron pipes. If the sphere made of other materials is adopted, the pump tube 1 cannot be compressed, or the surface of the pump tube 1 is damaged, because the spheres made of different materials have different rigidities; it is therefore necessary to use the cast iron ball 9 and to use the cast iron ball 9 as a direct contact limit for the pump pipe 1, the cast iron ball 9 being in point contact with the pump pipe 1. The point contact can enable the pump pipe 1 to shift and roll in multiple directions in the limiting hole 301, which provides a corresponding relation with uncertainty of the acting direction of the vibration force applied to the pump pipe 1, so that the pump pipe 1 is not limited by the limiting part 32 in any direction when being subjected to the vibration force, but simultaneously the vibration force can be completely transmitted to the limiting part 32, and finally the vibration force is eliminated by the tension spring 8 and the pressure spring 10.
For convenience of installation, a guide ring 2 is fixedly arranged on the vertical support plate 5, the guide ring 2 can be used for the pump pipe 1 to vertically penetrate up and down, the guide ring 2 is fixedly connected with the vertical support plate 5 through a support, the diameter of an inner hole of the guide ring 2 is slightly larger than that of the outer wall of the pump pipe 1, specifically 2 cm-4 cm, and 3cm is the best. The guide ring 2 facilitates the pump pipe 1 to be inserted into the limit hole 301 to guide the pump pipe 1, and can prevent the pump pipe 1 from damaging the swing block 3 when the pump pipe 1 suffers from large vibration force, so that the protection effect is achieved. The aperture of the guide ring 2 is larger than the outer diameter of the pump pipe 1, which belongs to the optimized specific numerical value in the using process, and the numerical value is selected to ensure that the swinging block 3 is not damaged, thereby better protecting the swinging block 3.
