Technical Field

[0001] The utility model relates to the technical field of chimneys, in particular to a chimney inner sleeve installation device. Background Art

[0002] The interior of current concrete chimneys is easily corroded, and it is usually necessary to install an inner sleeve inside the concrete chimney. When installing the inner sleeve on a concrete chimney with a height of 100-150 meters, the inner sleeve is heavy and a large-tonnage crane is required for hoisting. The construction period for hoisting the inner sleeve is between 30-50 days, the crane takes a long time to use, and the hoisting cost is high.

[0003] After searching, the patent number is CN210685565U, which discloses an inner cylinder lifting device for chimney reconstruction, including a chimney and an inner cylinder in the chimney, the inner cylinder is installed on a base, and a hanger for lifting cylinder sections is installed on the top of the chimney. The hanger is also reinforced by connecting with the bottom platform through steel wire ropes. The inner cylinder sections are lifted by the steel structure lifting equipment on the top of the chimney to avoid the trouble of the inner cylinder sections entering the chimney from the flue opening at the bottom of the chimney. At the same time, the crane only needs to be used when installing and disassembling the hanger, which reduces the use time of the crane and reduces the lifting cost. However, this method requires manual fixation of the hanger with the top of the chimney through the connecting legs below, which is inconvenient to operate and has a low safety factor. Utility Model Content

[0005] In order to solve the above technical problems, the technical solution of the utility model is: a chimney inner sleeve installation device, characterized in that: it includes a base, a column is provided on the base, a cross beam is vertically provided on the upper end of the column, a running beam is vertically provided at the bottom of the cross beam, an electric hoist is slidably provided on the running beam, and a hook for lifting the inner sleeve is provided under the electric hoist.

[0006] Furthermore, the base includes a supporting platform, a first convex ring and a second convex ring. The first convex ring and the second convex ring are arranged on the supporting platform, the second convex ring is arranged inside the first convex ring, an annular groove is formed between the first convex ring and the second convex ring, and a working platform is provided on the lower periphery of the first convex ring.

[0007] Furthermore, the first convex ring is threadedly connected with a bolt, and the bolt passes through the first convex ring and extends into the ring groove.

[0008] Furthermore, the supporting platform is an annular disk.

[0009] Furthermore, the outer diameter of the second convex ring is smaller than the inner diameter of the chimney, and the inner diameter of the first convex ring is larger than the outer diameter of the chimney.

[0010] Furthermore, the center of the second convex ring is the same as the center of the first convex ring.

[0011] The utility model adopts the above technical scheme, and has the following advantages compared with the prior art: when installing the inner sleeve inside the chimney, a crane is first used to place the chimney inner sleeve installation device on the top of the chimney so that the top of the chimney matches the annular groove in the base, and then a plurality of bolts are installed on the side wall of the first convex ring so that the bottom of the bolts bears against the outer wall of the chimney, thereby fixing the chimney and the base.

[0012] After the fixation is completed, the inner sleeve is hoisted on the electric hoist. The electric hoist slides along the running beam to the top of the chimney, and moves downward to place the inner sleeve in the chimney.

[0013] The chimney inner sleeve installation device is installed on the top of the chimney. Only a crane is needed when installing and disassembling the chimney inner sleeve installation device, which reduces the installation period and reduces the cost. At the same time, the base is directly matched with the top of the chimney. The operator can install bolts on the working platform and tighten the chimney with the bolts. The operation is convenient and the safety factor is high. BRIEF DESCRIPTION OF THE DRAWINGS
