[0002] The turbo expander is a key component necessary for obtaining cold energy in air separation equipment, natural gas liquefaction separation equipment, and low-temperature crushing equipment. It is the heart that ensures the stable operation of the entire equipment. Its main principle is to use a certain pressure of gas to perform adiabatic expansion in the turbo expander to do external work and consume the internal energy of the gas itself, so that the gas itself is strongly cooled to achieve the purpose of refrigeration.

[0003] A turbine expander lifting and adjusting seat with a publication (announcement) number of CN219606476U includes an expander body and a base, the top of the base is fixedly connected with a bracket, the number of the brackets is four, and the four brackets are distributed on the outside of the expander body, one of the brackets is fixedly connected with a motor on the top, the output end of the motor is fixedly connected with a screw, the bottom end of the screw is fixedly connected with a rotating shaft, the outer wall of the rotating shaft is rotatably connected to the inner wall of the base, and the outer wall of the screw is threadedly connected with a fixed plate. After the turbine expander is installed, the motor is started to drive the screw to rotate to realize the lifting and lowering of the expander body. After lifting to the appropriate position, the pin is inserted into the sliding rod and the fixed plate body to limit the position of the fixed plate, so as to support the expander body and keep the support stable, thereby solving the problem that traditional turbine expanders are inconvenient to lift and lower during use;

[0004] However, since the base for installing the turbine expander has a certain height and the fixing plate for connecting with the turbine expander feet also has a certain height, the turbine expander needs to be lifted by a lifting device during installation so that the feet at the four corners of its bottom can be effectively connected to the fixing plate, which makes it inconvenient to install the turbine expander on the base.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-Figure 6 The utility model provides a technical solution: a common base for facilitating the installation of a turbine expander, comprising a support base 1, a groove 2 is provided on the top of the support base 1, a wedge-shaped platform 3 is provided inside the groove 2, one side of the wedge-shaped platform 3 is provided with an inclined surface inclined upward, and both ends of the other side of the wedge-shaped platform 3 are symmetrically fixedly connected with a fixing frame 4, the other end of the fixing frame 4 is fixedly connected to the inner wall of the groove 2, and a plurality of rollers 6 are rotatably connected between the two fixing frames 4 through a rotating shaft 5 at equal intervals;

[0023] The four corners of the top of the support seat 1 are fixedly connected with a support frame 7, a travel groove 8 is provided on the side wall of the support frame 7, a travel leg 12 is slidably connected inside the travel groove 8, and a matching sedimentation groove 9 is provided at the top of the support seat 1 corresponding to the position of the travel leg 12, and the sedimentation groove 9 is connected to the groove 2;

[0024] The top of the support frame 7 is fixedly connected to a servo motor 10 through a fixed frame, and the output end of the servo motor 10 is fixedly connected to a screw rod 11 through a coupling. The other end of the screw rod 11 moves through the support frame 7 and extends to the inside of the travel groove 8. One end of the screw rod 11 located inside the travel groove 8 is threaded through the travel support foot 12.

[0025] The four servo motors 10 are electrically connected to an external power supply through a PLC controller. The TB6600 PLC controller can effectively control the speed and direction of the servo motors 10 and can effectively ensure that the four servo motors 10 can be started synchronously.

[0026] The travel support foot 12 is an L-shaped structure. The travel support foot 12 of the L-shaped structure can effectively slide along the travel groove 8 and can limit itself, which can effectively prevent the travel support foot 12 from rotating with the rotation of the screw rod 11.

[0027] A screw hole 13 is formed through the top of the travel support foot 12 away from the screw rod 11. The screw hole 13 can effectively connect the support foot of the turbine expander by bolts.

[0028] The roller 6 is higher than the height of the fixing frame 4, so that the roller 6 can effectively support the turbine expander, making it easier to push the turbine expander on the base.

[0029] Specifically, in the initial state, as shown in the attached Figure 2 or attached Figure 3 As shown, at this time, the travel leg 12 is retracted to the inside of the sedimentation tank 9 under the drive of the screw rod 11, so that the top of the travel leg 12 is flush with the top of the fixing frame 4, and because the roller 6 is slightly higher than the top of the fixing frame 4, the turbine expander will not be inconvenient to move when it moves to the top of the fixing frame 4 due to the interference of the travel leg 12;

[0030] When in use, the turbine expander can be easily pushed along the inclined surface of the wedge-shaped platform 3 to the roller 6 on the fixed frame 4, and the turbine expander can be pushed along the roller 6. At this time, the turbine expander is located on the base, and because the travel support foot 12 is retracted to the inside of the sedimentation tank 9, the turbine expander can be pushed to align the support foot of the turbine expander with the travel support foot 12. After alignment, the bolts can be passed through the support foot of the turbine expander and threadedly connected with the screw holes on the travel support foot 12, so that the turbine expander can be easily installed, and no lifting equipment is required for auxiliary lifting during the installation process.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
