Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-4, a lifting device for engineering detection, includes a bottom plate 1, a pushing and lifting mechanism, a secondary lifting mechanism, a protection mechanism, and a moving mechanism. The pushing and lifting mechanism includes an installation groove 2, which is opened inside the bottom plate 1. A first electric push rod 3 is fixedly installed inside the installation groove 2. The secondary lifting mechanism is arranged on the upper side of the first electric push rod 3. The secondary lifting mechanism includes a first installation frame 4. A motor 5 is fixedly installed on the upper side of the first installation frame 4. The output end of the motor 5 is fixedly connected to a threaded rod 6. A first lifting block 7 is arranged outside the threaded rod 6. One side of the first lifting block 7 is fixedly connected to a lifting plate 8. The upper side of the first electric push rod 3 is fixedly connected to a second installation frame 9. A guide rod 10 is fixedly connected inside the second installation frame 9. A second lifting block 11 is arranged outside the guide rod 10. The threaded rod 6 is threadedly connected to the first lifting block 7. The first lifting block 7 is arranged inside the first installation frame 4 and is slidably connected to the first installation frame 4. The second lifting block 11 is arranged inside the second installation frame 9 and is slidably connected to the second installation frame 9 and the guide rod 10 respectively. One end of the threaded rod 6 is rotatably connected to the first installation frame 4. The first installation frame 4 and the second installation frame 9 have the same shape. First, the staff will stand on the lifting plate 8. The first electric push rod 3 extends and retracts to make the lifting plate 8 perform the first lift. Then, the motor 5 drives the threaded rod 6 to rotate. Through the threaded connection between the threaded rod 6 and the first lifting block 7, through the setting of limiting the first lifting block 7 by the first installation frame 4, and through the setting of limiting the second lifting block 11 by the second installation frame 9 and the guide rod 10, the second lifting block 11 stabilizes the lifting plate 8, and the first lifting block 7 lifts inside the first installation frame 4 to drive the lifting plate 8 to perform the second lift. The two lifts can adjust the height in stages, so as to achieve more accurate positioning and control. And the two lifts can relieve the impact load brought by a single large-scale lift, reducing the risk of equipment failure and damage.

[0021] In one aspect of this embodiment, the edge of the lifting plate 8 is protected by the connecting rod 12 and the fence 13. When the staff needs to enter the lifting plate 8, through the setting that the blocking rod 15 is hinged to the setting groove 14, the blocking rod 15 can be rotated to open an entrance and exit for the fence 13. At this time, the staff can enter the upper surface of the lifting plate 8, and then reset the blocking rod 15 so that one end of the blocking rod 15 is stuck in the card slot 16, thereby closing the fence 13. This can not only protect the safety of the staff, but also make it more convenient to enter and exit the upper side of the lifting plate 8.

[0022] In one aspect of this embodiment, when it is necessary to adjust the position of the device, the second electric push rod 18 can be activated to drive the universal wheel 19 out of the hidden groove 17. The universal wheel 19 can lift the bottom plate 1, so that the universal wheel 19 contacts the placement position. Through the settings of the cross block 21 and the fixing rod 20, the handle 22 is fixed at the upper side position of the bottom plate 1. Workers can conveniently move the device with the assistance of the handle 22, making it more convenient to move the device.

[0023] Working principle of the present utility model: When the lifting device for engineering detection is in use, the second electric push rod 18 is activated to drive the universal wheel 19 out of the hidden groove 17. The universal wheel 19 can lift the bottom plate 1, so that the universal wheel 19 contacts the placement position. Through the settings of the cross block 21 and the fixing rod 20, the handle 22 is fixed at the upper side position of the bottom plate 1. Workers can conveniently move the device with the assistance of the handle 22. After moving the device to the position where detection is required, the second electric push rod 18 drives the universal wheel 19 to retract, so that the bottom plate 1 contacts the placement position. The blocking rod 15 is rotated to open an access opening in the fence 13. At this time, the worker can enter above the lifting plate 8, and then the blocking rod 15 is reset, so that one end of the blocking rod 15 is stuck in the card slot 16, thereby closing the fence 13. Then, the first electric push rod 3 is extended and retracted to make the lifting plate 8 perform the first lifting. After that, the motor 5 drives the threaded rod 6 to rotate. Through the setting of the threaded connection between the threaded rod 6 and the first lifting block 7, through the setting of the first mounting frame 4 to limit the first lifting block 7, and through the setting of the second mounting frame 9 and the guide rod 10 to limit the second lifting block 11, the second lifting block 11 stabilizes the lifting plate 8, so that the first lifting block 7 lifts in the first mounting frame 4 to drive the lifting plate 8 to perform the second lifting, so that workers can detect the engineering work at high places. In this solution, all electrical equipment is powered by an external power supply.
