Meanwhile, in the description of the present specification, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted", "connected", and "connected" are to be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; the two components can be directly connected or indirectly connected through an intermediate medium, and the two components can be communicated with each other, so that the specific meaning of the terms in the invention can be understood through specific situations for a person skilled in the art.
Example 1
As shown in fig. 1 and 3, a steam seal cooler of a steam turbine is provided, wherein a mounting seat 2 is arranged at the bottom of the steam seal cooler 1, a moving mechanism is detachably connected to the bottom of the mounting seat 2, the moving mechanism comprises a wheel shaft detachably connected with the mounting seat 2, the wheel shaft comprises a front wheel shaft 3 and a rear wheel shaft 5, a front wheel 4 is arranged on the front wheel shaft 3, and a rear wheel 6 is arranged on the rear wheel shaft 5; the one end of mount pad 2 can be dismantled and be connected with the rope handle, the one end of mount pad 2 is provided with the end connecting hole, and the end connecting hole can be dismantled with the rope handle and be connected.
The bottom of the mounting seat 2 is provided with a front connecting hole 7 and a rear connecting hole 8, the front connecting hole 7 is in threaded connection with the front wheel shaft 3, and the rear connecting hole 8 is in threaded connection with the rear wheel shaft 5; the front connecting hole 7 and the rear connecting hole 8 are counter bores, and the front wheel shaft 3 and the rear wheel shaft 5 are of split type structures.
Example 2
As shown in fig. 2 and 3, the present embodiment is the most different from the above embodiments in that the front connecting hole 7 and the rear connecting hole 8 are through holes, and the front wheel axle 3 and the rear wheel axle 5 are both of an integral structure.
The construction difficulty of this embodiment is greater than embodiment 1 (it is hard to waste time to set up the through-hole than the counter bore), but the use intensity of shaft is higher, can bear heavier vapor seal cooler, and the user selects which kind of implementation mode to use according to the operation requirement of self.
Example 3
The present embodiment is the biggest difference from the above embodiments in that a protective guard is disposed on an edge of the mounting base 2; the height of the guard rail is higher than that of the steam seal cooler 1.
In the embodiment, a protection mechanism is additionally arranged for the steam seal cooler, so that the safety protection of the working environment is more facilitated.
Because the steam seal cooler is generally large in size and heavy in weight, a plurality of cranes and forklifts are often required to cooperate in installation (generally, the cranes lift the steam seal cooler to move, and after the cranes reach an installation place, the forklifts are used for adjusting the installation direction and the position of the steam seal cooler, and the like), so that time and labor are wasted, safety accidents are caused if the steam seal cooler falls off in the installation process, and the life safety of workers is threatened.
Therefore, the design concept of the scheme is that the steam seal cooler is additionally provided with the detachable moving mechanism, so that the steam seal cooler can be conveniently moved, and the steam seal cooler can be conveniently and quickly installed.
The application comprises the following steps: lifting the steam seal cooler for a certain distance (the steam seal cooler is lifted by a forklift), then installing the moving mechanism on the mounting seat of the steam seal cooler, placing the steam seal cooler on the ground, pushing and pulling the steam seal cooler to reach the mounting place, lifting the steam seal cooler by the forklift, detaching the moving mechanism, and then adjusting the mounting position.
The steam seal cooler that the steam turbine was used is bulky, but it is infeasible basically to utilize the freight train to remove the mounted position, because the freight train is generally great, and factory installation space is less (because there is the existence of other main equipment), so the freight train generally does not go, so this application has fine practicality, the steam seal cooler is bulky, when the manual work can promote, just with the manual work, when the steam seal cooler is very big very heavy, can add the motor on the shaft (on the front wheel axle or on the rear wheel axle), the motor is connected with the master gear, the master gear is connected with the driving chain, the driving chain is connected with the slave gear, the slave gear cup joints epaxially (on the front wheel axle or on the rear wheel axle), so, the motor drive front wheel is being controlled to the manual work, the rear wheel rotates, remove the steam seal cooler can.
Although the present invention has been described in detail with reference to the drawings and preferred embodiments, the present invention is not limited thereto, and those skilled in the art can make various equivalent modifications or substitutions to the embodiments of the present invention without departing from the spirit and essential characteristics of the present invention, and these modifications or substitutions should be within the scope of the present invention/any person skilled in the art can easily conceive of changes or substitutions within the technical scope of the present invention, and therefore, the scope of the present invention should be defined by the appended claims.
