As shown in fig. 1 and 2, the deformation preventing support structure for replacing a steel tank bottom plate according to the present utility model and the structural schematic diagram for supporting a steel tank body thereof are shown, respectively, and as can be seen from the drawings, the deformation preventing support structure for replacing a steel tank bottom plate according to the present utility model comprises: a support frame 16 fixed to the center of the bottom plate 200 of the steel can 100; a jack 17 whose cylinder body is fixedly connected with the supporting frame; a support ring 15 fixedly connected to the piston rod of the jack; and a plurality of telescopic support rods which are arranged around the periphery of the support ring and used for supporting the inner side wall of the steel tank body.
According to the utility model, the bottom of the support frame and the steel tank bottom plate (the bottom plate can be the original bottom plate when the bottom of the original tank body is removed or a bottom plate positioned in the center of the original bottom plate, for example, a steel plate is cut at the center of the original bottom plate, the area of the steel plate is suitable for installation of the support frame, the bottom plate at the corresponding position of the steel plate can be finally installed after the bottom plates at other positions are all constructed), the bottom plate is fixedly connected (such as welded) together from the center, a cylinder body of a jack is fixed at the top of the support frame, a circular supporting ring is fixedly installed at the tail end of a piston rod of the jack, a plurality of telescopic supporting rods extending radially outwards along the supporting ring are arranged at the periphery of the supporting ring, the telescopic supporting rods can be adjusted according to actual supporting needs and locked at the position through locking assemblies after the required position is reached, and the tail ends of the telescopic supporting rods can be contacted with the inner side wall of the tank body (see figure 1), so that when the original steel tank bottom plate is removed from the bottom of the original tank body or a new bottom plate is welded at the lower opening of the tank body of the original bottom plate, the tank body can be partially deformed, the original tank body can be locally adjusted, and the original tank body can be restored.
The support ring is a support ring with a track, as shown in fig. 3 and 4, one end of the telescopic support rod is arranged in the track of the support ring and can slide along the track. When the support ring is designed, the outer side wall of the support ring is provided with a small-outside and large-inside stepped groove, a track is formed through the stepped groove, one end of the telescopic support rod is T-shaped, namely, the telescopic support rod is provided with a clamping part matched with a large-diameter part of the stepped groove of the support ring track and an extending part which is positioned at the center of the clamping part and used for penetrating through a small-diameter part of the stepped groove, and the clamping part is arranged in the track and can move along the track, so that the position of the telescopic support rod in the track can be adjusted according to the actual requirement in repairing operation. When the position of the telescopic supporting rod relative to the supporting ring reaches the preset requirement, the telescopic supporting rod can be locked at the position through the locking component.
The locking assembly comprises two or more locking bolts 19 which can penetrate through the clamping parts of the telescopic support rods, and the telescopic support rods can be locked with the radial positions of the support rings in a manner of penetrating through the clamping parts of the telescopic support rods and propping against the inner side walls of the tracks of the support rings through the locking bolts, so that the telescopic support rods are prevented from moving radially along the support rings. Correspondingly, a plurality of through holes are formed in the clamping part of the telescopic support rod. Further, the locking assembly may further include a spacer 20 that may be sleeved outside the telescopic support rod clamping portion, where the spacer may be a plastic spacer, and the inner ring of the spacer is sized to correspond to the outer size of the telescopic support rod clamping portion, and the outer ring of the spacer is sized to correspond to the inner wall of the track. The relative position of the telescopic supporting rod and the supporting ring in the height direction can be locked through the cushion block, and the telescopic supporting rod is prevented from shaking relative to the supporting ring.
As shown in fig. 1 and 2, the telescopic support rod of the present utility model comprises: a first support bar 12 having one end slidably connected to the support ring rail; a second supporting rod 10 with one end for contacting the inner side wall of the steel tank body; and sleeves 11 with two ends for respectively connecting the first support rod and the second support rod. The other end of the first supporting rod and the other end of the second supporting rod are respectively provided with external threads, and the inner wall of the sleeve is provided with internal threads matched with the external threads of the two supporting rods. When the tank body is deformed, the length of the telescopic supporting rod can be adjusted by rotating the sleeve, so that the telescopic supporting rod supports the inner side wall of the tank body which is deformed, and the purpose of adjusting the deformation part of the tank body is achieved.
Because the inner diameter of the tank body is large, usually more than 10 meters, the length of the supporting rod is long, and because the supporting rod is an elongated rod, the supporting rod can bend in the process of being independently supported, and therefore, the tank body is further provided with a diagonal drawing assembly for reinforcing the supporting strength of the plurality of telescopic supporting rods, and as shown in figure 1, the diagonal drawing assembly comprises a support fixedly arranged at the upper part of a supporting ring, a vertical supporting rod 14 connected with the support, and a plurality of inclined pull rods 13, wherein one end of each inclined pull rod is connected with the top end of the vertical supporting rod, and the other end of each inclined pull rod is fixedly connected with the first supporting rod of the plurality of telescopic supporting rods. In order to prevent the supporting force of the diagonal assembly on the support rod from being influenced when the telescopic support rod adjusts the position (i.e. angle) of the relative track, the support and the vertical support rod can be connected together in a rotary connection mode, and the position of the vertical support rod relative to the support can be locked after the vertical support rod rotates to a required angle, and the structure can refer to the prior art and is not described in detail herein.
Further, an arc-shaped supporting plate 9 can be installed at the position of the inner side wall of the tank body, which is used for being contacted with the telescopic supporting rod, and the shape of the arc-shaped supporting plate is matched with the inner side wall of the tank body and is fixedly connected with the inner side wall of the tank body, such as welding.
The number and the size of the telescopic supporting rods can be determined according to the size of the tank body.
In summary, the deformation-preventing supporting structure for replacing the steel tank bottom plate can drive the supporting ring and the telescopic supporting rods to synchronously lift along with lifting of the tank body through the jack, so that safety of the tank body in a lifting process is guaranteed, the inner side wall of the steel tank body is supported through the telescopic supporting rods annularly arranged on the periphery of the supporting ring, local deformation of the tank body is prevented, adjustment of a local deformation area of the tank body is achieved, and the deformation-preventing supporting structure is beneficial to repairing and continuing use of the tank body after repairing and can be suitable for local replacement of tank walls of tank bodies with similar large sizes.
