Further, a hanging part is arranged at the rear part of the bottom plate 2. The hanging part is arranged in the utility model in order to prevent the hanging and the fixing between the heater and the heater supporting plate 1, and can be arranged at the rear part or the side part when only the heater supporting plate 1 is arranged; may be provided at the rear or side of the bottom plate 2 when the bottom plate 2 is provided; the present utility model is preferably provided at the rear of the base plate 2.
Further, the fixing piece and the hanging part are arranged at the same end. The fixing piece and the hanging part are arranged at the same end, so that the end can be determined as the upper end, and the characteristic of avoiding operation at the bottom of the heater when the fixing piece is required to be installed or detached during hoisting is realized; in the prior art, when the heater is in a vertical state, in order to avoid the phenomenon that the tail part of the heater swings greatly or rubs the ground, maintenance personnel are required to stand on the lower parts of the crane and the heater to support, and as the operation is performed on the bottoms of the crane and the heater, great potential safety hazards exist, and safety accidents are easily caused; the utility model can avoid the occurrence of the safety accidents through the arrangement.
Further, the fixing piece is an internal threaded hole arranged at the end part of the supporting cross rod 4 and a bolt 5 matched with the internal threaded hole; the position of the internal threaded hole at the end part of the supporting cross rod 4 is matched with the position of the bolt hole on the sealing flange 6 in the synthesis tower heater. Through the arrangement, the sealing flange 6 in the heater can be coupled with the utility model, the coupling can realize the tight fixation of the sealing flange and the utility model on the basis of not changing the structure of the heater, and the supporting cross rod 4 not only ensures the structure of the utility model to be firmer, but also protects the heater, and can provide position assurance for the installation of the fixing piece.
Further, the hanging part is a fixed block 7, and a circular hanging groove 8 is formed in the inner side end surface of the fixed block 7. The round hanging groove 8 is arranged, so that the purpose of continuous and soft adaptation with related equipment such as steel pipes in a fixed object can be facilitated.
The utility model also comprises a supporting base plate 9, and the height of the supporting base plate 9 is consistent with the height of the fixed block 7. By providing the support pad 9 and making its height coincide with the height of the fixed block, it is possible to maintain a horizontal state when the heater is placed horizontally, facilitating maintenance and lifting.
The working principle of the utility model is as follows: as shown in fig. 1-4, the utility model can be applied to the characteristics of changing the position of the heater and avoiding damage during disassembly and assembly; specifically, when the heater needs to be disassembled, an maintainer disassembles the heater, and at the same time, the crane lifts the special tool to be in a vertical state and carries out hanging through the hanging part; after the hanging is finished, the crane lifts the heater (the heater is in a vertical state at the moment), and an maintainer passes through a bolt hole on the sealing flange 6 through the bolt hole on the sealing flange 6 to be matched with an internal threaded hole at the end part of the supporting cross rod 4, so that the heater is fixedly connected with a special tool; the crane is used for hoisting the heater, the heater and the special tool are converted from a vertical state to a horizontal state, and the special tool falls onto the upper part of the supporting base plate 9 in the later period of conversion to the horizontal state; finally, the bolts 5 are disassembled; when the crane needs to be installed, the crane converts the heater and the special tool from a horizontal state to a vertical state by hoisting the heater, and carries out hanging through the hanging part; after the hanging is finished, an overhauling personnel dismount the bolt 5 on the upper part to separate the heater from the special tool, and the crane continuously hoists the heater after the separation to enable the heater to enter the synthesis tower, so that the subsequent operation is finished. The special tool can protect the heater, can effectively avoid the problem of damaging the insulating porcelain ring or bending the heater with high strength, can overcome the operation that two cranes are required to be matched for operation to change the position of the heater in the prior art, and can also avoid the risk that personnel are in operation at the bottoms of the heater and the cranes.
Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
