Description

Technical Field

[0001] The utility model relates to a shock-absorbing support, in particular to an anti-overturning structural support suitable for high-load heavy equipment. Background Art

[0002] At present, a Chinese patent with authorization announcement number CN209602947U discloses a seismic isolation rubber bearing, which includes an upper bearing plate, a lower bearing plate, a rubber body and a limit assembly; the rubber body is fixedly arranged between the upper bearing plate and the lower bearing plate, the top surface of the rubber body is fixedly connected to the bottom surface of the upper bearing plate, and the bottom surface is fixedly connected to the top surface of the lower bearing plate; the limit assembly includes a retaining wall and a middle seat plate; the retaining wall is arranged on the bottom surface of the upper bearing plate; the middle seat plate is arranged around the rubber body, and includes a vertical part and a horizontal part, the top end of the vertical part is located between the retaining wall and the rubber body, and the horizontal part is fixedly connected to the lower bearing plate.

[0003] When the horizontal displacement of the rubber body is large, the vertical part of the limit assembly blocks the rubber body, and the retaining wall blocks the vertical part. The horizontal part of the limit assembly is fixedly connected to the lower support plate, so that the rubber body can be limited so that its displacement does not exceed the limit, thereby avoiding damage to the seismic isolation rubber bearing.

[0004] However, in the event of a strong earthquake, especially when subjected to vertical force, the equipment will drive the upper support plate to move upward synchronously, and when the lower support plate is fixed to the ground, the rubber body will be subjected to a large tensile force and easily broken. Utility Model Content

[0005] In view of this, the utility model aims to provide an anti-overturning structural support suitable for high-load heavy equipment, so as to achieve the purpose of making the upper rubber support and the lower rubber support not easily broken.

[0006] The cam is connected with the support frame of the lower frame under the support frame, and the lower frame is connected with the support frame of the lower frame under the support frame, and the cam is connected with the support frame of the lower frame under the support frame.

[0007] To implement the above technical solution, the upper support and the lower support are stacked, and through the limiting action of the stop rod and the fixed block, the upper fixed plate on the lower support can only move up and down with the lower rubber support. Combined with the up and down movement of the upper rubber support, the equipment has a better buffer stroke in the vertical direction. When the lower mounting plate collides with the stop block, the force is transmitted to the lower fixed plate through the stop rod and the fixed block, so that under the action of the pulling force of the stop rod, the fixed block and the lower fixed plate, the lower rubber support and the upper rubber support are not easily broken; the upper support can dissipate and reset the energy in the horizontal direction to reduce the horizontal vibration of the equipment, so that the equipment located above the upper support is not easily overturned due to the shift of the center of gravity.

[0008] As a preferred solution of the utility model, two of the fixing block, the stop rod and the stop block are provided, and the two fixing blocks are respectively located on both sides of the lower rubber support.

[0009] By implementing the above technical solution, the lower rubber support on the lower support can only be deformed along the height direction of the barrier rod but cannot be deformed along the horizontal direction, and the production cost is reduced.

[0010] As a preferred solution of the utility model, a copper restraining column is fixedly connected inside the lower rubber support, and two ends of the copper restraining column are fixedly connected to the upper fixing plate and the lower fixing plate respectively.

[0011] The implementation of the above technical solution improves the structural strength of the lower rubber bearing, and because copper has good ductility, it is not easy to be broken.

[0012] As a preferred solution of the utility model, a plurality of steel plate layers are fixedly connected to the upper rubber support, the plurality of steel plate layers are arranged at intervals and along the height direction of the upper rubber support, a lead core is fixedly connected inside the upper rubber support, and the two ends of the lead core are respectively fixedly connected to the upper mounting plate and the lower mounting plate.

[0013] To implement the above technical solution, the arrangement of the steel plate layer enables the upper rubber bearing to effectively limit horizontal movement while allowing vertical movement, and the lead core can provide vertical support and absorb seismic energy through plastic deformation of the lead core.

[0014] As a preferred solution of the utility model, the lower mounting plate is provided with an upper mounting hole, the upper fixed plate is provided with a lower mounting hole corresponding to the upper mounting hole, the upper fixed plate is provided with a placement recessed hole, the lower mounting hole is located inside the placement recessed hole, a positioning bolt is passed through the upper mounting hole, the positioning bolt passes through the lower mounting hole, a positioning sleeve is threadedly connected to the positioning bolt, and the positioning sleeve is used to press tightly against the bottom wall of the placement recessed hole.

[0015] To implement the above technical solution, the positioning bolt is passed through the upper mounting hole and the lower mounting hole from top to bottom, and the positioning sleeve is then threadedly connected to the positioning bolt so that the positioning sleeve is located in the placement recessed hole and the positioning sleeve is tightly pressed against the inner wall of the placement recessed hole, making it difficult for the lower mounting plate and the upper fixing plate to separate.

[0016] As a preferred solution of the utility model, a sliding hole is opened on the inner wall of the placement recessed hole, a sliding rod is slidably connected in the sliding hole, an elastic part is connected between the inner wall of the sliding hole and the sliding rod, and a limiting hole for passing the sliding rod is opened on the side wall of the positioning sleeve.

[0017] To implement the above technical solution, the sliding rod is moved toward the sliding hole, the positioning sleeve is threadedly connected to the positioning bolt, and after the positioning sleeve is tightly pressed against the bottom wall of the recessed hole, the sliding rod is loosened, and the end of the sliding rod is embedded in the limiting hole through the elastic force of the elastic member, and the sliding rod is in contact with the inner wall of the limiting hole. At the same time, the sliding rod is in contact with the inner wall of the sliding hole, so that the positioning sleeve is not easy to rotate, thereby making it difficult for the positioning sleeve to fall off the positioning bolt.

[0018] As a preferred solution of the utility model, a guiding bevel is provided at one end of the positioning sleeve close to the lower mounting hole, and the guiding bevel is used to interfere with the end of the sliding rod. A limiting surface is provided at one end of the positioning sleeve away from the lower mounting hole. A plurality of limiting surfaces are arranged along the axis of the positioning sleeve, and the limiting hole is located between the guiding bevel and the limiting surface.

[0019] To implement the above technical solution, the positioning sleeve is placed on the positioning bolt and rotated so that the guiding inclined surface contacts the end of the sliding rod, and the sliding rod moves along the guiding inclined surface toward the sliding hole. As the positioning sleeve continues to move along the axial direction of the positioning bolt, the positioning sleeve contacts the bottom wall of the placement recessed hole and continues to rotate to lock it. At this time, the limiting hole corresponds to the sliding rod, and the end of the sliding rod is inserted into the limiting hole, which is convenient for installation. Clamping the limiting surface with pliers to rotate the positioning sleeve is more labor-saving.

[0020] As a preferred solution of the utility model, the side wall of the positioning bolt has a convex portion and a concave portion, and the convex portion on the adjacent positioning bolt is embedded in the concave portion.

[0021] To implement the above technical solution, the convex part is embedded in the concave part, so that the positioning bolt is not easy to rotate, and the positioning bolt is not easy to separate from the positioning sleeve. BRIEF DESCRIPTION OF THE DRAWINGS
