Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0028] Example 1:

[0029] The utility model provides a pressure type lifting pulley, referring to Figures 1 to 4 As shown, the pressure-type lifting pulley includes a lifting pulley assembly 1, a pressure collection assembly 2 and a communication device 3.

[0030] The pressure collection assembly 2 includes an acquisition element 21 . The acquisition element 21 and the communication device 3 are both arranged on the lifting pulley assembly 1 ; the acquisition element 21 is electrically connected to the communication device 3 .

[0031] When in use, the lifting pulley assembly 1 performs lifting work. During this process, the acquisition element 21 obtains the load information of the lifting pulley assembly 1 in real time and transmits it to the communication device 3. The communication device 3 transmits the load information to the processing terminal 4. The staff can easily understand the load information of the lifting pulley assembly 1 through the processing terminal 4, thereby grasping its load status.

[0040] During the lifting process, the lifting pulley assembly 1 is loaded, and its pressure acts on the elastic metal film 211, causing the elastic metal film 211 to deform, and the resistance value on its surface changes accordingly. At this time, the communication device 3 transmits the changed resistance value in the form of an electrical signal to the processing terminal 4, and the processing terminal 4 converts the resistance value into a pressure value. As a result, the staff can intuitively obtain the load status of the lifting pulley assembly 1 during the lifting process.

[0047] The pressure collection assembly 2 is arranged inside the bearing 12 .

[0048] When the lifting tackle assembly 1 is loaded, the pulley 13 pulls the load, and the pressure on the pulley 13 acts on the elastic metal film 211 through the bearing 12, causing the elastic metal film 211 to deform.

[0049] As an optional embodiment, the lifting tackle assembly 1 includes a lifting bracket 14 , and the mounting shaft 11 is arranged on the lifting bracket 14 ; the communication device 3 is arranged on the lifting bracket 14 .
