[0035] Embodiment 1

[0036] As Figures 1 to 5 shown, this embodiment discloses a limiting device for a shock-absorbing pedestal, which can effectively limit the shock-absorbing pedestal 3 without expanding the foundation 4, and ensure the shock-absorbing effect of the shock-absorbing pedestal 3. The limiting device includes a first limiting structure 1 and a second limiting structure 2.

[0037] Referring to Figure 1 and Figure 2 , the shock-absorbing pedestal 3 is arranged on the foundation 4. The first limiting structure 1 can be connected to the foundation 4. The first limiting structures 1 are arranged on both opposite sides of the shock-absorbing pedestal 3 along the first direction on the foundation 4. The first limiting structure 1 includes a blocking member 11, and the blocking member 11 can limit the displacement of the shock-absorbing pedestal 3 in the first direction; the second limiting structure 2 includes a first limiting member 21 and a second limiting member 22. Both the first limiting member 21 and the second limiting member 22 can be connected to the shock-absorbing pedestal 3, and the first limiting member 21 and the second limiting member 22 are arranged at intervals. The blocking member 11 is located in the space formed between the first limiting member 21 and the second limiting member 22, and the blocking member 11 can cooperate with the first limiting member 21 and the second limiting member 22 to limit the displacement of the shock-absorbing pedestal 3 in the second direction. The first direction is perpendicular to the second direction. Among them, the first direction is the Figure 2 X direction in Figure 2 , and the second direction is the

[0038] The limiting device of the shock-absorbing pedestal provided in this embodiment limits the displacement of the shock-absorbing pedestal 3 in the first direction by arranging the first limiting structures 1 on both opposite sides of the shock-absorbing pedestal 3 along the first direction. When the shock-absorbing pedestal 3 generates positive and negative displacements in the first direction during operation, the blocking members 11 on both sides can limit the displacement of the shock-absorbing pedestal 3 in the first direction. By arranging the first limiting member 21 and the second limiting member 22 on the shock-absorbing pedestal 3, and the blocking member 11 is located in the space formed between the first limiting member 21 and the second limiting member 22, when the shock-absorbing pedestal 3 generates positive and negative displacements in the second direction during operation, the blocking member 11 can cooperate with the first limiting member 21 and the second limiting member 22 to limit the displacement of the shock-absorbing pedestal 3 in the second direction. That is, without expanding the original foundation 4 of the shock-absorbing pedestal 3, only by setting the first limiting structure 1 and the second limiting structure 2 can the displacement of the shock-absorbing pedestal 3 relative to the foundation 4 in the first direction and the second direction be limited, ensuring the shock-absorbing effect of the shock-absorbing pedestal 3, and solving the problem that the foundation 4 cannot be expanded due to limited space to effectively limit the shock-absorbing pedestal 3.

[0039] Exemplarily, in this embodiment, the first limiting member 21 and the second limiting member 22 are rectangular steel plates, and both the first limiting member 21 and the second limiting member 22 are welded to the shock-absorbing pedestal 3. Preferably, the side of the rectangular steel plate in contact with the blocking member 11 is not welded, and the other three sides are welded and fixed to the shock-absorbing pedestal 3 to ensure that the first limiting member 21 and the second limiting member 22 are firmly fixed, and at the same time prevent the side of the first limiting member 21 and the second limiting member 22 in contact with the blocking member 11 from being non-straight due to welding, resulting in different displacements of the blocking member 11 in the positive and negative directions in the second direction in the space and affecting the limiting effect.

[0040] Preferably, the blocking member 11 is arranged parallel to the side wall of the shock-absorbing pedestal 3, which can effectively prevent the blocking member 11 from being bent and ensure the limiting effect of the limiting device on the shock-absorbing pedestal 3.

[0041] Optionally, refer to Figure 1 and Figure 2 , the first limiting structure 1 further includes a base 12, the blocking member 11 is arranged on the base 12, and the base 12 can be detachably connected to the foundation 4, so as to facilitate the installation or disassembly of the first limiting structure 1 on the foundation 4, enabling the first limiting structure 1 to be used multiple times, and also facilitating subsequent replacement and repair of the limiting device and the shock-absorbing pedestal 3, reducing the maintenance cost.

[0042] In an alternative embodiment, the first limiting structure 1 further includes a plurality of fasteners 14, the base 12 is provided with connection holes corresponding to the plurality of fasteners 14 one by one, and the fasteners 14 pass through the connection holes and are fastened to the foundation 4 to facilitate the installation and disassembly of the base 12 on the foundation 4.

[0043] Exemplarily, refer to Figure 1 and Figure 2, the fastener 14 is a bolt, the connection hole is a bolt hole provided on the base 12, the base 4 is provided with mounting holes corresponding to a plurality of bolts one by one, the head of the bolt abuts against the surface of the base 12, and the rod portion of the bolt passes through the bolt hole and is tightened in the mounting hole.

[0044] In another alternative embodiment, the base 12 can also be connected to the base 4 by bonding. The connection process is simple, the operation is convenient, and there is no need to drill holes on site, saving construction time.

[0045] Optionally, the first limiting structure 1 further includes a support member 13. One end of the support member 13 is connected to the base 12, and the other end of the support member 13 is connected to the blocking member 11, so that a stable triangle is formed between the support member 13, the base 12 and the blocking member 11, ensuring the overall stability of the first limiting structure 1 and being beneficial to improving the limiting effect of the blocking member 11.

[0046] Exemplarily, refer to Figure 1 and Figure 2 , in this embodiment, the base 12, the blocking member 11 and the support member 13 are all steel plates, with high strength and not easily deformed under the collision of the shock-absorbing pedestal 3. The base 12 and the blocking member 11 are arranged perpendicular to each other, so that the triangle formed between the support member 13, the base 12 and the blocking member 11 is a right triangle, and the overall first limiting structure 1 is more stable, which is beneficial to restricting the shock-absorbing pedestal 3. The base 12 and the blocking member 11 are welded, and the support member 13 is also welded to the base 12 and the blocking member 11. The electric welding connection has high strength, improves the overall rigidity of the first limiting structure 1, and further makes the first limiting structure 1 not easily deformed under the collision of the shock-absorbing pedestal 3.

[0047] In other embodiments, finished angle steel can be selected. One limb of the angle steel is the base 12, the other limb is the blocking member 11, and the support member 13 is a steel plate. After selecting the finished angle steel, there is no need to weld the base 12 and the blocking member 11 on site, saving time and labor costs and improving the installation efficiency.

[0048] Preferably, in order to improve the overall rigidity of the first limiting structure 1, when multiple support members 13 are provided, the multiple support members 13 are symmetrically arranged to provide symmetric support force for the blocking member 11, so that the blocking member 11 is not easily turned over under the collision of the shock-absorbing pedestal 3; moreover, when the support member 13 is welded to the blocking member 11 and the base 12, a relatively large local stress will be generated at the connection due to welding. Symmetrically arranging the support members 13 can prevent the blocking member 11 and the base 12 from being damaged due to uneven stress distribution, so as to ensure the normal use of the first limiting structure 1.

[0049] Specifically, in this embodiment, refer to Figure 1 and Figure 2, two supporting members 13 are provided, and a plurality of fasteners 14 are symmetrically arranged on both sides of the two supporting members 13, so that the first limiting structure 1 is uniformly stressed and is not prone to tipping over and deformation; in other embodiments, the plurality of fasteners 14 can also be arranged in the space formed between the two supporting members 13, as long as the plurality of fasteners 14 and the supporting members 13 are symmetrically arranged on the base 12, so that the base 12 and the blocking member 11 are uniformly stressed.

[0050] Optionally, a plurality of bases 12 are provided, and the dimensions of the plurality of bases 12 in the first direction are different, and the plurality of bases 12 can be selectively detachably connected to the foundation 4. With such a setting, the limiting device includes a set of bases 12 with different size specifications in the first direction. The plurality of bases 12 are located between the edge of the foundation 4 and the shock-absorbing pedestal 3 and can be selectively detachably connected to the foundation 4. Therefore, when the staff installs the limiting device, they only need to select a base 12 with a suitable size according to the distance between the shock-absorbing pedestal 3 and the edge of the foundation 4, which improves the applicable range of the limiting device.

[0051] Exemplarily, refer to Figure 5 , in this embodiment, the distance between the edge of the foundation 4 and the shock-absorbing pedestal 3 is B, and the dimension of the base 12 in the first direction only needs to be not greater than the distance B.

[0052] Optionally, the blocking member 11 and the shock-absorbing pedestal 3 form a clearance fit in the first direction, and the blocking member 11 and the first limiting member 21 and the second limiting member 22 both form a clearance fit in the second direction. With such a setting, a certain margin is provided for the movement of the shock-absorbing pedestal 3 in the first direction and the second direction, avoiding the tight connection between the limiting device and the shock-absorbing pedestal 3, resulting in resonance between the limiting device and the shock-absorbing pedestal 3, thereby reducing the vibration of the foundation 4 in the horizontal direction ( Figure 2 the X direction and the Y direction in Figure 2 ), and at the same time, the setting of the clearance is also beneficial to the movement of the shock-absorbing pedestal 3 in the vertical direction ( the Z direction in

[0053] ), thereby giving full play to the shock-absorbing effect of the shock-absorbing pedestal 3. Figure 5 Figure 2 Exemplarily, refer to

[0054] Optionally, a first shock-absorbing member is provided in the gap between the shock-absorbing pedestal 3 and the blocking member 11; and / or, second shock-absorbing members are provided in the gaps between the blocking member 11 and the first limiting member 21 and between the blocking member 11 and the second limiting member 22. With such an arrangement, the vibration received by the limiting device can be reduced, thereby reducing the vibration received by the foundation 4 and improving the shock-absorbing effect; it can also prevent damage caused by hard contact between the limiting device and the shock-absorbing pedestal 3.

[0055] In an alternative embodiment, the first shock-absorbing member can be attached to the side of the blocking member 11 facing the shock-absorbing pedestal 3, and / or, the second shock-absorbing member is attached to the sides of the first limiting member 21 and the second limiting member 22 facing the blocking member 11; in another alternative embodiment, the first shock-absorbing member can be filled in the gap between the blocking member 11 and the shock-absorbing pedestal 3, and the second shock-absorbing member is filled in the gap between the blocking member 11 and the first limiting member 21 (the blocking member 11 and the second limiting member 22).

[0056] The first shock-absorbing member of this embodiment is made of a flexible material; and / or, the second shock-absorbing member is made of a flexible material so that the limiting device can be in flexible contact with the shock-absorbing pedestal 3. When the shock-absorbing pedestal 3 collides with the limiting device, it can play a buffering role, effectively preventing damage caused by hard contact between the limiting device and the shock-absorbing pedestal 3, reducing the damage rate of the limiting device and the shock-absorbing pedestal 3, and also reducing the vibration received by the foundation 4 to a certain extent, improving the shock-absorbing effect.

[0057] Exemplarily, the flexible material is rubber or silica gel, etc., which has good buffering effect and long service life.

[0058] In other embodiments, the first shock-absorbing member is a spring, which is provided on the side of the blocking member 11 close to the shock-absorbing pedestal 3; and / or, the second shock-absorbing member is a spring, which is provided on the side of the blocking member 11 close to the first blocking member 11 and the second blocking member 11. The elastic force of the spring can offset part of the impact force of the shock-absorbing pedestal 3, thereby achieving a shock-absorbing effect and a buffering function.

[0059] Optionally, there are several groups of the first limiting structure 1 and the second limiting structure 2, and several groups of the first limiting structure 1 and the second limiting structure 2 are arranged at intervals along the first direction. With such an arrangement, it can be applicable to the situation where the size of the shock-absorbing pedestal 3 is relatively large and it is difficult for a group of the first limiting structure 1 and the second limiting structure 2 to fully limit the displacement of the shock-absorbing pedestal 3, so as to ensure the limiting effect on the shock-absorbing pedestal 3.

[0060] In an alternative embodiment, two sets of first limiting structures 1 and second limiting structures 2 are provided, that is, two first limiting structures 1 and two second limiting structures 2 are arranged at intervals along the second direction on each side of the shock-absorbing pedestal 3 along the first direction to ensure the limiting effect on the shock-absorbing pedestal 3; in another alternative embodiment, three or more sets of first limiting structures 1 and second limiting structures 2 can also be provided. The specific number of sets provided is mainly determined according to the dimensions of the shock-absorbing pedestal 3 along the first direction and the second direction, as long as the shock-absorbing pedestal 3 can be fully limited on the foundation 4.

[0061] Embodiment 2

[0062] As Figures 1 to 5 shown, this embodiment provides a shock-absorbing pedestal 3, including a shock-absorbing body 31, a plurality of elastic shock absorbers 32, and the limiting device of the shock-absorbing pedestal in Embodiment 1. The plurality of elastic shock absorbers 32 are arranged at intervals along the circumferential direction of the shock-absorbing body 31, and each elastic shock absorber 32 is fixed to the foundation 4. The second limiting structure 2 of the limiting device is connected to the shock-absorbing body 31.

[0063] The shock-absorbing pedestal 3 provided in this embodiment can reduce the vibration received by the foundation 4 in two ways, namely, through the elastic shock absorbers 32 and the shock-absorbing body 31, ensuring the shock-absorbing effect; it can also install the shock-absorbing body 31 on the foundation 4 with a smaller size through the limiting device.

[0064] Specifically, a water pump is installed on the shock-absorbing body 31. The shock-absorbing body 31 has sufficient inertial damping and can not vibrate with the water pump, effectively avoiding the occurrence of resonance. The elastic shock absorber 32 has elasticity. One end of it is connected to the foundation 4, and the other end is connected to the shock-absorbing body 31. Its elasticity can offset part of the vibration, thereby reducing the vibration received by the foundation 4. Referring to Figure 2 the orientation in, the height of the elastic shock absorber 32 along the vertical direction needs to be greater than the height of the shock-absorbing body 31 to prevent the shock-absorbing body 31 from directly contacting the foundation 4 and reducing the vibration received by the foundation 4.

[0065] Exemplarily, referring to Figure 3 , the shock-absorbing body 31 is a rectangular structure made of concrete, so that the mass of the shock-absorbing body 31 is relatively large and can have sufficient inertial damping; the concrete is also wrapped with a steel plate to facilitate the connection between the shock-absorbing body 31, the elastic shock absorbers 32, the limiting device, and the water pump.

[0066] In this embodiment, installation positions 311 that are recessed inward are provided at the four corners of the shock-absorbing body 31, and the elastic shock absorbers 32 are located within the installation positions 311, further saving the size occupied by the shock-absorbing pedestal 3 to facilitate the installation of the shock-absorbing pedestal 3 on a foundation 4 with a smaller size. In other embodiments, the plurality of elastic shock absorbers 32 can also be symmetrically arranged along the side wall of the shock-absorbing body.

[0067] In this embodiment, the elastic shock absorber 32 includes a first support 323, a second support 324, an elastic member 321 and a connecting rod 322. The elastic member 321 is sleeved outside the connecting rod 322. One end of the elastic member 321 is fixed to the first support 323, and the other end is fixed to the second support 324. The elastic member 321 can generate an elastic force in the vertical direction ( Figure 2 the Z direction in Figure 2 ). The first support 323 is connected to the top plate 312 of the shock-absorbing body 31, and the second support 324 is connected to the upper surface of the foundation 4. The connecting rod 322 extends in the vertical direction ( Figure 2 the Z direction in

[0068] ). One end of the connecting rod 322 is fixed to the first support 323, and a preset distance is left between the other end and the second support 324 to limit the deformation degree of the elastic member 321 and prevent the bottom of the shock-absorbing body 31 from colliding with the top surface of the foundation 4 due to excessive deformation of the elastic member 321, thereby reducing the damage rate of the shock-absorbing body 31 and the foundation 4. The preset distance is determined by the length of the connecting rod 322 in the vertical direction and the height of the shock-absorbing body 31, as long as a gap can be formed between the bottom of the shock-absorbing body 31 and the top surface of the foundation 4 to provide space for the shock-absorbing body 31 to move in the vertical direction (

[0069] the Z direction in Exemplarily, the elastic member 321 is a spring, and the connecting rod 322 is a bolt. The bolt extends in the vertical direction, the rod portion of the bolt is located inside the spring, and the head of the bolt abuts against the upper surface of the shock-absorbing body 31. The above is only the specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Those skilled in the art should understand that any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention fall within the protection scope and the disclosure scope of the present invention.
