TECHNICAL FIELD
[0001] The present disclosure relates to the technical field of saddles, and more particularly, to an anti-overturning rolling saddle device. BACKGROUND
[0002] The commonly used sliding saddle has the following disadvantages in use: in the case where the working temperature of the equipment is high, the conventional sliding saddle generates relative displacement with the foundation after the equipment generates axial expansion, which results in sliding friction, and the frictional resistance is 30% of the saddle supporting force. When the weight of the equipment is heavy, the frictional force is large, which can generate a large bending moment on the equipment, thereby causing harm to the stable operation of the equipment.
[0003] In order to avoid large frictional force between the sliding saddle and the foundation, a roller is arranged under the sliding saddle in the prior art. The arrangement schemes of the roller are different, for example, two groups of large rollers are arranged at the bottom of the saddle, and for another example, a group of small and complex rolling balls are arranged at the bottom plate of the saddle. Although both of the two schemes can realize rolling contact between the saddle and the foundation, the ground bolts between the saddle and the foundation are cancelled due to the structural limitations of the two schemes. However, according to the provisions in “Horizontal Vessels” NB / T47042-2014, the earthquake force can generate overturning moment on the equipment in the earthquake working condition, and the cancellation of the ground bolts can cause the equipment to be unable to withstand the earthquake overturning moment, thereby causing a safety hazard to the operation of the equipment in special working conditions. CONTENT OF THE UTILITY MODEL

[0005] Specifically, the present disclosure provides an anti-overturning rolling saddle device, which comprises a bottom plate, a supporting plate, two side plates, a plurality of round steel rolling balls, a web plate, a pad plate, and at least one fixing assembly. The supporting plate is located below the bottom plate and opposite to the bottom plate in a vertical direction.

The plurality of round steel rolling balls are arranged in the cavity, and each round steel rolling ball is configured to protrude out of the cavity and rollingly contact a foundation located below the supporting plate. The web plate is fixed on the bottom plate. The pad plate is fixed on an end of the web plate away from the bottom plate. The at least one fixing assembly is configured to slidably fix the bottom plate and the supporting plate to the foundation in an axial direction perpendicular to the vertical direction.

One end of the anchor bolt is fixed to the foundation in sequence through a first bolt hole on the bottom plate and a second bolt hole on the support plate along the vertical direction, and the other end of the anchor bolt is fixed by the nut. The first bolt hole and the second bolt hole are opposite to each other along the vertical direction and extend along the axial direction.
[0007] Optionally, the first bolt hole and the second bolt hole are both oblong holes.
[0008] Optionally, the at least one fixing assembly comprises a plurality of fixing assemblies, which are uniformly distributed on the bottom plate.

[0025] One embodiment of the present disclosure provides an anti-overturning rolling saddle device. As shown in Figure 1 and Figure 2 , the anti-overturning rolling saddle device comprises a bottom plate 4, a supporting plate 6, two side plates 7, a plurality of round steel balls 5, a web plate 2, a cushion plate 1 and at least one fixing assembly. The supporting plate 6 is located below the bottom plate 4 and opposite to the bottom plate 4 in the vertical direction Z. The two side plates 7 are respectively located on both sides of the bottom plate 4 and connect the bottom plate 4 and the supporting plate 6, thereby forming a cavity 12. The plurality of round steel balls 5 are arranged in the cavity 12, and each round steel ball 5 is configured to protrude out of the cavity 12 and rollingly contact the foundation 13 located below the supporting plate 6. The web plate 2 is fixed on the bottom plate 4, and the cushion plate 1 is fixed on the end of the web plate 2 away from the bottom plate 4. The at least one fixing assembly is configured to slidably fix the bottom plate 4 and the supporting plate 6 to the foundation 12 in the axial direction Y perpendicular to the vertical direction Z.
[0026] In a preferred embodiment of the present disclosure, as shown in Figure 1 and Figure 2 , each of the at least one fixing assembly comprises an anchor bolt 8 and a nut 9. One end of the anchor bolt 8 is fixed to the foundation 13 in the vertical direction Z through a first bolt hole 10 on the bottom plate 4 and a second bolt hole 10' on the supporting plate 6 in sequence, and the other end of the anchor bolt 8 is fixed through the nut 9. The first bolt hole 10 and the second bolt hole 10' are opposite to each other in the vertical direction Z and extend in the axial direction Y. In this way, after the equipment generates axial expansion due to high working temperature, the rolling saddle device generates axial sliding, and the first bolt hole 10 and the second bolt hole 10' extending in the axial direction Y ensure that the axial sliding can be realized, and the plurality of round steel balls 5 realize the rolling contact between the rolling saddle device and the foundation 13, so that the rolling saddle device can greatly reduce the friction between the rolling saddle device and the foundation 13 while retaining the anchor bolt 8, that is, while the rolling saddle device is stably connected to the foundation 13, thereby avoiding generating large bending moment on the equipment and ensuring that the equipment can operate completely stably under special working conditions (such as earthquake).
[0027] In one preferred embodiment of the present disclosure, as shown in Figure 3 and Figure 4 The length of the oblong hole in the axial direction Y can be set based on the axial expansion amount determined according to the working temperature of the equipment.
[0028] In one preferred embodiment of the present disclosure, as shown in Figure 1 The at least one fixing assembly includes a plurality of fixing assemblies, which are uniformly distributed on the bottom plate 4, thereby further improving the ability of the rolling saddle device to withstand overturning moment.
[0029] In one preferred embodiment of the present disclosure, the supporting plate 6 is provided with at least one round steel ball hole 11 for mounting a plurality of round steel balls 5, and the width of the round steel ball hole 11 in the axial direction Y is smaller than the diameter of the round steel ball 5, thereby avoiding the round steel ball 5 from falling off.
[0030] In one preferred embodiment of the present disclosure, as shown in Figure 4 The at least one round steel ball hole 11 extends in the horizontal direction X perpendicular to the axial direction Y and the vertical direction Z. In this way, at least one round steel ball 5 can be mounted in each round steel ball hole 11, thereby allowing as many round steel balls 5 as possible to be arranged, which is conducive to ensuring the smooth axial sliding.
[0031] In one preferred embodiment of the present disclosure, as shown in Figure 1 The cushion plate 1 is in a concave arc shape, which is conducive to placing the equipment and preventing the equipment from falling off.
[0032] In one preferred embodiment of the present disclosure, the cushion plate 1 and the bottom plate 4 are connected by a web plate 3. By providing the web plate 3, the bending and torsional strength of the web plate 2 is improved, thereby preventing the rolling saddle device from deforming or breaking when subjected to external force.
[0033] In one preferred embodiment of the present disclosure, the anti-overturning rolling saddle device further includes two other side plates 7, which are located in the cavity 12 and connected to the bottom plate 4 and the supporting plate 6. The addition of the two other side plates 7 can further improve the stability of the rolling saddle device.
[0034] In the rolling saddle device of the present disclosure, the gusset plate 1, the web plate 2, the rib plate 3 and the bottom plate 4 are welded to form a saddle, then the round steel ball 5 is placed between the bottom plate 4 and the supporting plate 6, and the bottom plate 4 and the supporting plate 6 are connected through the side plate 7, thereby forming the rolling saddle device. When installing the equipment, first, the anchor bolt 8 is fixed to the foundation 13 through the supporting plate 6 and the bottom plate 4, and the anchor bolt 8 is fixed with the nut 9, and when the equipment is running, the rolling saddle device slides axially relative to the foundation 13 due to the axial expansion, the nut 9 generates friction with the bottom plate 4, but the contact area between the nut 9 and the bottom plate 4 is small, the friction generated is small, and the influence on the equipment is small. When an earthquake occurs, the rolling saddle device remains stable through the pulling force generated by the anchor bolt 8 and the nut 9, which can protect the equipment from overturning and ensure the safe and stable operation of the equipment.
