Description

Technical Field

[0001] The invention belongs to the technical field of construction, and in particular relates to a desiliconization trough pipe row transportation bracket and a method for hoisting a heating pipe bundle. Background Art

[0002] The desiliconization tank is the main equipment for high-pressure dissolution of alumina. Due to long-term use, the heating tube bundle in the desiliconization tank has broken, the weld of the header tube has cracked, and serious material accumulation has occurred, affecting the normal operation of the desiliconization tank. In order to ensure the normal operation of the equipment, the heating tube bundle must be replaced.

[0003] The removal and reinstallation of the existing old pipe banks and upper and lower ring pipes takes a long time and consumes a lot of manpower, which not only wastes labor costs and crane machine shift fees, but also delays the overhaul period. The existing lifting method is to transport the pipe bundle from the outside of the desiliconization tank through the manhole door to the inside of the desiliconization tank, and then lift it multiple times with a hand winch and transport it to the construction site. The construction period is long and the labor and equipment investment is large. Summary of the invention

[0004] The purpose of the present invention is to solve the technical problems that the existing pipe bank removal and reinstallation takes a long time, consumes a lot of manpower, wastes labor costs and crane machinery shift fees, and delays the overhaul period, as well as the existing lifting method has a long construction period and a large amount of labor and equipment investment, and provide a desiliconization slot pipe bank transportation bracket and a heating tube bundle lifting method. In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0005] A desiliconization tank pipe row transportation bracket, characterized in that it includes a pairing device clamped on the annular channel steel on the upper inner wall of the desiliconization tank and a transportation bracket arranged on the upper side of the desiliconization tank stirring shaft, and an inspection manhole is opened on the top of the desiliconization tank. The desiliconization tank stirring shaft is used as a transportation carrier to transport the pipe row to the construction site at one time, and the pipe bundle can be hoisted, transported, paired and installed within a range of 360 degrees, which greatly reduces the time required for dismantling and reinstalling the pipe row, saves manpower, labor costs and crane machine shift fees, and advances the overhaul period. In addition, such an arrangement is more convenient, quick and efficient, reduces the labor intensity of on-site construction personnel, improves the safety production factor, and has good test results.

[0006] Furthermore, the pairing device includes a pairing bracket and a manual hoist, wherein the manual hoist is arranged at the end of the bracket arm of the pairing bracket, and the heating tube bundle is lifted by the manual hoist and paired and installed with the upper heating ring tube and the lower heating ring tube.

[0007] Furthermore, the pairing bracket includes a bracket base and a bracket arm. The bracket base and the bracket arm are integrally designed. The bracket base is used for clamping onto the annular channel steel. The bracket base adopts a mobile operation and can move on the annular channel steel. After the pipe row is hoisted to the installation position, it can be quickly paired and welded, enabling hoisting, transferring, pairing, and installation within a 360-degree range, greatly reducing the time for hoisting, transferring, pairing, and installing the pipe row.

[0008] Moreover, the lifting bracket includes a connecting rod and a hook. The hook is arranged at one end of the connecting rod, and the other end of the connecting rod is used for connecting to the upper side of the stirring shaft of the desilication tank. The setting of the hook further ensures that when the heating pipe is hung on the connecting rod, it will not be thrown out due to the rotation of the stirring shaft.

[0009] Moreover, a tension bar is provided between the lifting bracket and the stirring shaft of the desilication tank to stabilize the lifting bracket.

[0010] A hoisting method for the heating tube bundle of a desilication tank includes the following steps:

[0011] Step 1, open a maintenance manhole at the top of the desilication tank;

[0012] Step 2, weld the pre-made lifting bracket to the upper side of the stirring shaft;

[0013] Step 3, use a crane to put the heating tube bundle into the desilication tank through the maintenance manhole at the top of the desilication tank, and hang the heating tube bundle on the lifting bracket with a steel wire rope;

[0014] Step 4, move the heating tube bundle to the intended installation position by rotating the stirring shaft;

[0015] Step 5, clamp the pairing bracket onto the annular channel steel on the upper part of the inner wall of the desilication tank, and the pairing bracket can move on the annular channel steel according to the pairing position;

[0016] Step 6, lift the heating tube bundle with a manual hoist and pair and install it with the upper heating ring pipe and the lower heating ring pipe;

[0017] Step 7, pair all the heating tube bundles one by one according to Steps 3 - 6 to achieve 360° dead-angle-free installation in place, that is, complete the installation of the heating tube bundle;

[0018] Step 8, after the installation is completed, remove the pairing bracket, cut off the lifting bracket, and close the maintenance manhole.

[0019] This method uses the stirring shaft of the desilication tank as a transfer carrier to transfer the pipe row to the construction site at one time. The tube bundle can be hoisted, transferred, paired, and installed within a 360-degree range, greatly reducing the construction period and also saving a large amount of labor and equipment investment.

[0021] 1. In the present invention, a pairing device is arranged on the upper annular channel steel on the inner wall of the desilication tank, and a lifting support is arranged on the upper side of the stirring rotating shaft of the desilication tank. Using the stirring rotating shaft of the desilication tank as a transfer carrier, the pipe row can be transferred to the construction site at one time. The pipe row lifting support can realize 360° dead-angle-free lifting, transfer, pairing and installation by only one person rotating the stirring rotating shaft, and accurately lift and transfer the pipe row to any installation position, greatly reducing the time required for pipe row demolition and reinstallation, saving labor, as well as labor costs and crane mechanical shift fees, and advancing the overhaul period. In addition, such an arrangement is more convenient, fast and efficient, reducing the labor intensity of on-site construction personnel and increasing the safety production coefficient, and the test effect is good.

[0022] 2. The pairing support of the present invention includes a support clamping seat and a support arm. The support clamping seat and the support arm are integrally designed. The support clamping seat is used for clamping on the annular channel steel, and the support clamping seat adopts a mobile operation and can move on the annular channel steel. After the pipe row is lifted and transferred to the installation position, it can be quickly paired and welded, realizing lifting, transfer, pairing and installation within a 360-degree range, greatly reducing the time for pipe row lifting, transfer, pairing and installation.

[0023] 3. The lifting support of the present invention includes a connecting rod and a hook. The hook is arranged at one end of the connecting rod, and the other end of the connecting rod is used for connecting with the upper side of the stirring rotating shaft of the desilication tank. The setting of the hook further ensures that when the heating pipe is suspended on the connecting rod, it will not be thrown out due to the rotation of the stirring rotating shaft.

[0024] 4. A stay bar is arranged between the lifting support and the stirring rotating shaft of the desilication tank of the present invention for stabilizing the lifting support.

[0025] 5. The method of the present invention uses the stirring rotating shaft of the desilication tank as a transfer carrier to transfer the pipe row to the construction site at one time, and can lift, transfer, pair and install the pipe bundle within a 360-degree range, greatly reducing the construction period and also greatly saving the input of labor and equipment.
