[0002] As we all know, due to the continuous acceleration of my country's domestic urbanization process, the available building area in my country is gradually decreasing. Therefore, in order to alleviate the housing pressure in my country, the housing in my country's cities is developing towards high-rise. In the process of building high-rise buildings, in order to facilitate the transportation of materials to high places, lifting frames are often used.
[0003] However, since there is no device on the existing lifting frame to remind people around when using the lifting frame, if the object being lifted falls from a height, people under the object may suffer serious injuries, or even threaten their lives.
[0004] Therefore, how to design an engineering lifting frame with a warning function has become our current problem to be solved. Utility Model Content

[0009] Furthermore, the alarm, sensor and controller are all electrically connected via wires.
[0010] Furthermore, the alarm is an audible and visual alarm.
[0011] Furthermore, a reinforcing beam is provided between the support column and the support beam.
[0012] Furthermore, the base is provided with a plurality of mounting holes.
[0013] (III) Beneficial effects
[0014] Compared with the prior art, the utility model provides a lifting frame with a warning function, which has the following beneficial effects:
[0015] The lifting frame with a warning function is provided with a connecting shaft, a pulley, a sensor, a trigger block, a controller and an alarm. When the lifting rope is used for lifting, the lifting rope will drive the pulley to rotate during the process of pulling the lifting rope, and the rotation of the pulley will drive the trigger block on the connecting shaft to rotate. The trigger block will trigger the sensor during the rotation process, and the sensor will transmit an electrical signal to the controller. The controller controls the alarm to issue an alarm prompt to warn the surrounding people, and the lifting work is relatively safe. BRIEF DESCRIPTION OF THE DRAWINGS

[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 1-4The utility model is a lifting frame with a warning function, comprising a base 1 and a support column 2 arranged on the top, a support beam 3 is arranged on the top of the support column 2, a connecting piece 4 is arranged on the support beam 3, a connecting shaft 5 is rotatably connected to the connecting piece 4, a pulley 6 is fixedly arranged in the middle of the connecting shaft 5, a lifting rope 7 is installed on the pulley 6, a hook 8 is arranged at one end of the lifting rope 7, a plurality of trigger blocks 11 are arranged on the connecting shaft 5, a mounting piece 9 is arranged on the side wall of the connecting piece 4, a plurality of sensors 10 for detecting the trigger block 11 are arranged on the mounting piece 9, and a controller 12 and an alarm 1 are arranged on the support beam 3. 3. When the sensor 10 detects the trigger block 11, it will output a high-level electrical signal. When the sensor 10 does not detect the trigger block 11, it will output a low-level electrical signal. When the electrical signal fed back by the sensor 10 to the controller 12 does not change for a long time, it proves that the pulley 6 does not rotate, and the controller 12 controls the alarm 13 to stop working. When the electrical signal fed back by the sensor 10 to the controller 12 switches between high and low levels, it proves that the pulley 6 rotates, and the controller 12 controls the alarm 13 to work. The controller 12 controls the alarm 13 to issue an alarm prompt to warn the surrounding people, and the safety is higher during the lifting work.
