DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Example 1

[0022] Reference Figure 1-5 A brick lifting device comprises a base 1 and a lifting platform 2. A cross beam 3 is arranged on the top of the base 1. A moving mechanism is arranged between the cross bar 3 and the base 1. A first motor 4 is fixedly installed on the top of the cross bar 3. A turntable 5 is installed on the output shaft of the first motor 4. The lifting platform 2 is placed on the base 1. A cable 6 is arranged on the top of the lifting platform 2. One end of the cable 6 extends to the turntable 5. The moving mechanism adjusts the interval between the cross beam 3 and the base 1. The moving mechanism comprises a first support rod 7 and a second support rod 8 installed on the base 1. A gap is arranged between the first support rod 7 and the second support rod 8. A threaded rod 9 is threadedly connected to the first support rod 7. A moving rod 10 is slidably arranged on the second support rod 8. The top of the moving rod 10 is installed at the bottom of the cross beam 3. The top of the threaded rod 9 is installed on the cross bar 3 through a bearing. A second motor 11 is installed on the cross bar 3. The output shaft of the second motor 11 is connected to one end of the threaded rod 9.

[0023] When the threaded rod 9 is rotated by the output shaft of the second motor 11, the threaded rod 9 will rotate on the first support rod 7, and the moving rod 10 will move on the second support rod 8, so that the height of the beam 3 relative to the base 1 can be changed, so that the height of the first motor 4 and the second motor 11 on the beam 3 can be adjusted, so that when the device is moving, the beam 3 will not be blocked by the railings in the room, making it easier to move the device, so that the device can be used in more areas.

[0024] Example 2

[0025] In the embodiment 1, the lifting platform 2 is pulled by the cable 6, so that the lifting platform 2 is very likely to shake during the movement on the device, which makes the device less safe. Based on the embodiment 1, the optimization is carried out. Figure 1-5A limiting mechanism is provided on one side of the lifting platform 2, and an extrusion rod 13 is provided on the limiting mechanism. When the lifting platform 2 is located at the second support rod 8, one end of the extrusion rod 13 is extruded on the outside of the second support rod 8. The limiting mechanism includes two fixed plates 14, and sleeve tubes 15 are installed on the two fixed plates 14. Extrusion rods 13 are slidably provided on the two sleeve tubes 15. One ends of the two extrusion rods 13 are close to the second support rod 8, and the other ends of the two extrusion rods 13 are installed with springs 16, and one ends of the two springs 16 are extruded on the two fixed plates 14.

[0026] The provided spring 16 can squeeze the fixed plate 14 and the squeezing rod 13, so that one end of the squeezing rod 13 will always be squeezed on the second support rod 8 or the moving rod 10, so that the lifting platform 2 is more stable when it moves on the second support rod 8 and the moving rod 10.

[0027] Example 2

[0028] Based on Example 1, optimization is performed. Figure 1-5 The two extrusion rods 13 are both equipped with rollers 17, the second support rod 8 and the moving rod 10 are both provided with grooves 18, the two rollers 17 are both rolled on the two grooves 18, the top of the second support rod 8 is opened in an arc shape, and reinforcing ribs 12 are provided on both sides of the first support rod 7.

[0029] The rollers 17 are provided in combination with the grooves 18 so that the lifting platform 2 is less likely to shake relative to the base 1, thereby making the device more stable.

[0030] The provided reinforcing ribs 12 can make the first support rod 7 more stable, thereby making the device less likely to shake during the process of lifting bricks, thereby making the device more stable.

[0031] The top of the second support rod 8 is opened in an arc shape, so that when the roller 17 moves from the groove 18 on the second support rod 8 to the groove 18 of the moving rod 10, the movement process of the roller 17 is smoother, making it easier for the roller 17 to move in the groove 18.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
