[0026] like Figures 1 to 4 As shown, the utility model is a shell and tube heat exchanger, comprising: a base 1, a mounting base 2 fixedly mounted on the top of the base 1, a heat exchanger body 3 fixedly mounted on the mounting base 2, a moving mechanism for facilitating the movement of the heat exchanger body 3, and a leveling mechanism for facilitating the leveling of the heat exchanger body 3 after movement.

[0027] The moving mechanism includes: a universal wheel 4, a rectangular opening is provided at the bottom of the base 1, the universal wheel 4 passes through the inner cavity of the rectangular opening, and drives the universal wheel 4 to lift and lower; the lifting assembly includes: a bidirectional screw 6 rotatably mounted on the base 1, a motor 5 that drives the bidirectional screw 6 to rotate, a threaded seat 7 threadedly connected to the bidirectional screw 6, a limiter 1 for limiting the threaded seat 7, a connecting rod 8 hingedly mounted on the bottom of the threaded seat 7, a movable plate 10 hingedly mounted at the bottom end of the connecting rod 8, and a limiter 2 for limiting the movable plate 10 when it moves; the universal wheel 4 is fixedly mounted on the bottom of the movable plate 10; the limiter 1 includes: a through hole opened on the threaded seat 7, a limiter 9 installed in the through hole; both ends of the limiter rod 9 are fixedly connected to the inner wall of the base 1; the limiter 2 includes: a slide bar 11 fixedly mounted on the side wall of the movable plate 10, and a slide groove opened on the inner wall of the base 1; the slide bar 11 slides in the slide groove.

[0028] In the present application, four universal wheels 4 are provided, which are respectively located at the four corners of the bottom of the movable plate 10. When the heat exchanger body 3 is moved, the motor 5 is started, and the motor 5 drives the universal wheel 4 to rotate. The threaded seat 7 can be limited by two limit rods 9, so that the threaded seat 7 moves along the axial direction of the bidirectional screw 6, so that the universal wheel 4 drives the two threaded seats 7 to approach each other, and the two threaded seats 7 drive the adjacent connecting rods 8 to move, and the connecting rods 8 drive the movable plate 10 to move downward. The movable plate 10 drives several universal wheels 4 to pass through the rectangular opening, so that several universal wheels 4 abut against the ground and lift the base 1 so that the bottom of the base 1 is separated from the ground. At this time, the movable plate 10 can drive the slide bar 11 to slide in the inner cavity of the slide groove, so that the movable plate 10 can be limited to avoid the movable plate 10 from deflecting, thereby improving the stability of the movable plate 10 when moving.

[0029] At this time, the arrangement of a plurality of universal wheels 4 makes it easy to move the heat exchanger body 3, avoiding the need for the heat exchanger to be shipped and transferred only by a crane due to its huge structure, thereby greatly saving manpower and material resources.

[0030] After moving to the required position, the direction of rotation of the starting motor 5 is changed, so that the two threaded seats 7 move away from each other, thereby moving several universal wheels 4 into the inner cavity of the base 1 and making the bottom of the base 1 contact the ground. At this time, the device can be easily fixed to prevent sliding during use, thereby improving the stability of the device during use.

[0031] The leveling mechanism includes: a support plate 14, a moving part that drives the support plate 14 to move; the moving part includes: a fixed plate fixedly installed on the side wall of the base 1, a threaded rod 12 threadedly connected to the fixed plate, and a rotating plate 13 fixedly installed on the top of the threaded rod 12; the bottom end of the threaded rod 12 is rotatably connected to the support plate 14.

[0032] In the present application, four groups of leveling mechanisms are provided, which are symmetrically distributed on both sides of the base 1. When the ground is uneven, by rotating the rotating plate 13, the rotating plate 13 drives the threaded rod 12 to rotate, and the threaded rod 12 drives the support plate 14 to move downward, so that the support plate 14 abuts the ground and lifts up the base 1, so that the position of the corresponding support plate 14 can be adjusted according to the tilt situation, so that the device can be leveled when the ground is uneven, so that the device remains in a horizontal state, thereby avoiding the device from tipping over and improving the stability of use.

[0033] A rubber pad is fixedly installed at the bottom of the support plate 14. By the provision of the rubber pad, the friction between the support plate 14 and the ground can be increased, thereby preventing the support plate 14 from sliding, further improving the stability of the device when in use.

[0034] Working principle: When in use, by starting the motor 5, the motor 5 drives the universal wheel 4 to rotate, and the threaded seat 7 can be limited by the two limiting rods 9, so that the threaded seat 7 moves along the axial direction of the bidirectional screw 6, so that the universal wheel 4 drives the two threaded seats 7 to approach each other, and the two threaded seats 7 drive the adjacent connecting rods 8 to move, and the connecting rods 8 drive the movable plate 10 to move downward, and the movable plate 10 drives several universal wheels 4 to pass through the rectangular opening, so that several universal wheels 4 abut against the ground and lift the base 1, so that the bottom of the base 1 is separated from the ground. At this time, the movable plate 10 can drive the slide bar 11 to slide in the inner cavity of the slide groove, so that the movable plate 1 can be moved. 0 is limited to avoid the movable plate 10 from deflecting, thereby improving the stability of the movable plate 10 when moving; at this time, the arrangement of several universal wheels 4 can facilitate the movement of the heat exchanger body 3, avoiding the need for consignment and transfer by crane due to the huge structure of the heat exchanger, which greatly saves manpower and material resources; after moving to the required position, the rotation direction of the motor 5 is changed by starting, thereby making the two threaded seats 7 move away from each other, so that the several universal wheels 4 move to the inner cavity of the base 1, and make the bottom of the base 1 abut against the ground, which makes it easy to fix the device to prevent sliding during use, thereby improving the stability of the device when in use.
