Description

Technical Field

[0001] The utility model relates to the technical field of supports, in particular to an anti-seismic support for construction equipment. Background Art

[0002] The commonly used supports on the market are usually used in conjunction with multiple sets of spring seats. When the outside is under pressure, the spring inside will deform, thereby converting the force on it into internal friction, thereby reducing the impact on the support. However, in actual use, since the elastic force of the spring is a fixed value and the deformation distance of the spring is large, once the outside of the support is subjected to a large force, the compression space of the spring will increase, causing the spring to cause a large displacement of the support when it rebounds, which greatly affects the stability of the support during use. For this reason, we propose an anti-seismic support for building machinery to solve the above problems. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a seismic support for construction machinery to solve the problems raised in the above-mentioned background technology.

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions: an anti-seismic support for construction machinery, comprising a lower base and an upper top plate arranged at the upper end of the lower base, a lower kit and an upper kit connected between the lower base and the upper top plate, the upper kit being inserted into the lower kit, anti-seismic springs being wound around the outside of the lower kit and the upper kit, a limiting ring being threadedly connected to the outside of the lower kit, the limiting ring being connected to the handle through a connecting piece, and a guide assembly being arranged at the bottom end of the handle.

[0005] As a preferred technical solution of the utility model, the guide assembly includes a telescopic groove opened inside the turning handle, a guide rod fixed at the top of the telescopic groove, a rotating groove opened at the bottom end of the lower kit and a rotating block arranged inside the rotating groove, a telescopic rod is fixed at the top of the rotating block, and the telescopic rod is sleeved on the outside of the guide rod.

[0006] As a preferred technical solution of the utility model, the outer part of the lower sleeve is provided with an external thread, and the inner thread of the limiting ring matches the outer thread of the lower sleeve.

[0007] As a preferred technical solution of the utility model, the bottom end of the anti-seismic spring is in contact with the top end of the limiting ring, and the top end of the limiting ring is polished.

[0008] As a preferred technical solution of the utility model, the outside of the rotating block is fully fitted with the inside of the rotating groove, and the rotating block and the rotating groove are slidably connected.

[0009] As a preferred technical solution of the utility model, a butterfly spring is wound around the outside of the guide rod.

[0010] Compared with the prior art, the utility model can achieve the following beneficial effects:

[0011] 1. By setting a limit ring at the bottom of the anti-seismic spring, the upper set is rotated to allow the limit ring to rotate along the surface of the lower set, so that the limit ring moves upward along the lower set under the action of the thread. As the limit ring moves upward, the upper set is squeezed by the limit ring to shrink, thereby achieving rapid adjustment of the shrinkage distance of the anti-seismic spring, placing the top plate to produce a large displacement, so that the device can adapt to different application scenarios and improve the stability of the device when in use;

[0012] 2. Through the setting of the guide assembly, including the cooperation of the telescopic slot, the guide rod, the telescopic rod, the butterfly spring, the rotating block and the rotating slot, when the turning handle is turned, the turning handle will drive the guide rod and the telescopic rod to rotate, and the rotating block at the bottom of the telescopic rod will slide along the rotating slot under the force, so that the turning handle can rotate in a circle along the center of the rotating slot, and as the limit ring moves up or down along the lower kit, the turning handle can drive the guide rod to move up or down along the inside of the telescopic rod, ensuring a stable connection between the guide rod and the telescopic rod, allowing the turning handle to rotate smoothly, and further improving the stability of the device during use.

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, purpose and efficacy of the utility model easy to understand, the utility model is further described below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the utility model, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the utility model. The experimental methods in the following embodiments are conventional methods unless otherwise specified, and the materials, reagents, etc. used in the following embodiments are all commercially available unless otherwise specified.

[0021] Embodiment:

[0022] like Figure 1-Figure 6 As shown, a seismic support for building equipment includes a lower base 1, an upper top plate 2 arranged at the upper end of the lower base 1, a lower set 31 and an upper set 32 ​​are connected between the lower base 1 and the upper top plate 2, the upper set 32 ​​is inserted into the lower set 31, and seismic springs 33 are wound around the outer parts of the lower set 31 and the upper set 32, the outer part of the lower set 31 is threadedly connected to a limiting ring 34, the limiting ring 34 is connected to a turning handle 36 through a connecting piece 35, and a guide component is arranged at the bottom end of the turning handle 36;

[0023] By setting a limiting ring 34 at the bottom end of the anti-seismic spring 33, when the compression space of the anti-seismic spring 33 needs to be adjusted, the upper sleeve 32 is rotated to allow the limiting ring 34 to rotate along the surface of the lower sleeve 31, and the limiting ring 34 is allowed to move upward along the lower sleeve 31 under the action of the thread. As the limiting ring 34 moves upward, the upper sleeve 32 is squeezed by the limiting ring 34 and contracts, thereby achieving the goal of quickly adjusting the contraction distance of the anti-seismic spring 33 and placing the upper top plate 2 to produce a larger displacement, so that the device can adapt to different application scenarios and improve the stability of the device during use.

[0024] In other embodiments, the guide assembly includes a telescopic slot 41 provided inside the turning handle 36, a guide rod 42 fixed to the top of the telescopic slot 41, a rotation slot 46 provided at the bottom end of the lower sleeve 31, and a rotation block 45 provided inside the rotation slot 46, a telescopic rod 43 is fixed to the top of the rotation block 45, and the telescopic rod 43 is sleeved outside the guide rod 42;

[0025] With this design, when the turning handle 36 is rotated, the turning handle 36 will drive the guide rod 42 and the telescopic rod 43 to rotate, and the rotating block 45 at the bottom end of the telescopic rod 43 will slide along the rotating groove 46 under the force, so that the turning handle 36 can rotate in a circle along the center of the rotating groove 46. As the limiting ring 34 moves up or down along the lower kit 31, the turning handle 36 can drive the guide rod 42 to move up or down inside the telescopic rod 43, ensuring a stable connection between the guide rod 42 and the telescopic rod 43, allowing the turning handle 36 to rotate smoothly, further improving the stability of the device during use.

[0026] In other embodiments, the lower sleeve 31 is provided with external threads on the outside, and the threads inside the limiting ring 34 match the threads on the outside of the lower sleeve 31;

[0027] Through this design, the limiting ring 34 can rotate along the outside of the lower sleeve 31, and the limiting ring 34 can be smoothly displaced upward or downward along the surface of the lower sleeve 31 under the action of the thread.

[0028] In other embodiments, the bottom end of the anti-vibration spring 33 contacts the top end of the limiting ring 34, and the top end of the limiting ring 34 is polished;

[0029] Through this design, when the limit ring 34 rotates along the outside of the lower sleeve 31, the bottom end of the upper sleeve 32 can slide along the outside of the top end of the limit ring 34, allowing the anti-seismic spring 33 to smoothly receive the squeeze deformation force of the limit ring 34, thereby preventing the limit ring 34 from driving the upper sleeve 32 to rotate.

[0030] In other embodiments, the outside of the rotating block 45 is fully fitted with the inside of the rotating groove 46, and the rotating block 45 and the rotating groove 46 are slidably connected;

[0031] Through this design, when the rotating block 45 slides along the inside of the rotating groove 46, it can effectively prevent the rotating block 45 from shaking during the movement, and the rotating block 45 can guide the turning handle 36 to rotate stably.

[0032] In other embodiments, a butterfly spring 44 is wound around the outside of the guide rod 42;

[0033] Through this design, the butterfly spring 44 can apply a downward force to the guide rod 42, so that the guide rod 42 can be quickly reset when the guide rod 42 moves in the telescopic rod 43.

[0034] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them.
