Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-5This utility model discloses a moving device for a heavy-duty machine frame, including a pulley 1 arranged on one side of the heavy-duty machine frame 6. The pulley 1 is installed in the ground in the direction of movement of the heavy-duty machine frame 6. The pulley is used to change the direction of force transmission. A pull rope 2 is wound on the pulley 1. One end of the pull rope 2 is connected to the heavy-duty machine frame 6, and the other end is connected to the hook of the crane. The pull rope 2 is pulled by the upward force of the crane. After the pulley 1 changes the direction, the heavy-duty machine frame 6 is pulled to move in the specified direction, replacing manual labor and improving the pulling efficiency. The structure is simple and easy to use.

[0025] The pulley 1 can be detachably installed on the ground, and the pull rope 2 is detachably connected to the heavy frame 6 and the crane. This allows the pulley 1 to be installed on the ground and the pull rope 2 to be connected between the heavy frame 6 and the crane when needed. After use, the pulley 1 and pull rope 2 can be removed to avoid affecting the normal use of the installation position of the pulley 1 and the normal use of the crane, making the use more flexible.

[0026] An electromagnet 3 is installed below the pulley 1. The electromagnet 3 is embedded in the ground and its top surface does not protrude from the ground. When in use, the electromagnet 3 is activated to magnetically fix the pulley 1 in the predetermined position. When the use is finished, the electromagnet 3 is turned off and the pulley 1 is removed. Compared with the use of buckles, screws and other methods, disassembly and assembly are more convenient.

[0027] The bottom of the pulley 1 is equipped with a pulley seat 102 that cooperates with the electromagnet 3. The pulley 1 and the pulley seat 102 are connected by a pulley frame 101. The pulley frame 101 is fixedly installed on the pulley seat 102, and the pulley 1 is rotatably installed between the pulley frames 101. The bottom of the pulley seat 102 is provided with a cover plate 103. The size of the cover plate 103 in the top view is larger than that of the pulley seat 102. The function of the cover plate 103 is to make the pulley 1 and the pulley seat 102 more stable when placed on the ground and to increase the contact area with the electromagnet 3.

[0028] A proximity switch 4 is installed on one side of the electromagnet 3 to detect the distance between the cover plate 103 and the ground. The proximity switch 4 is electrically connected to the electromagnet 3 and the trolley switch. When the electromagnet 3 is activated, and the proximity switch 4 detects that the cover plate 103 has left the ground, the proximity switch 4 sends a signal to shut down the trolley. This is to prevent the trolley from still pulling the heavy frame 6 via the pull rope 2 when the pulley 1 and the electromagnet 3 are not fixedly connected. This is to prevent the pull rope 2 from getting caught on other equipment or personnel, and to prevent the trolley from directly pulling the heavy frame 6 and causing it to tip over, thereby improving the safety of the device during use.

[0029] Here, the electromagnet 3 includes an electromagnet body 301 and a magnetic shielding ring 302. The magnetic shielding ring 302 is a sleeve structure made of pure iron. The magnetic shielding ring 302 is fitted around the electromagnet body 301, while the cover plate 103 is located directly above the electromagnet body 301. The function of the magnetic shielding ring 302 is to reduce the influence of magnetic force on the proximity switch 4 without affecting the electromagnet body 301's magnetic attraction to the cover plate 103.

[0030] The proximity switch 4 includes a proximity switch body 401 and a mounting base 402. The proximity switch body 401 is mounted on the magnetic shielding ring 302 via the mounting base 402.

[0031] On the other side of the electromagnet 3, a buzzer alarm 7 is also installed. The electromagnet 3, the proximity switch 4, and the buzzer alarm 7 are electrically connected. When the proximity switch 4 sends a signal to stop the train, it also sends a signal to activate the buzzer alarm 7 and emit an alarm sound. This is used to notify the staff to deal with the problem in a timely manner through the alarm sound, so as to avoid other accidents caused by the staff not discovering the problem in time, and further improve safety.

[0032] A protective net 8 is installed on top of the buzzer alarm 7. The protective net 8 is installed flush with the ground to protect the buzzer alarm 7. At the same time, the mesh structure does not affect the sound transmission of the buzzer alarm 7.

[0033] In general, it involves excavating a recessed trench with an opening at the top in the ground, and installing an electromagnet 3, a proximity switch 4, and a buzzer alarm 7 inside the trench, with the top not exceeding the ground height so as not to affect the flatness of the workshop floor.

[0034] The pull rope 2 includes a first pull rope 201 and a second pull rope 202 connected to the first pull rope 201. The ends of the two first pull ropes 201 near the heavy frame 6 are connected to hooks 204, and the ends of the two first pull ropes 201 away from the heavy frame 6 are connected to the first pull ropes 201. The heavy frame 6 is welded with a hanging ring 5 that cooperates with the hooks 204. When in use, the hooks 204 are hung on the hanging ring 5.

[0035] The end of the second pull rope 202 away from the first pull rope 201 passes around the pulley 1. The end of the second pull rope 202 away from the first pull rope 201 is connected to a pull ring 203 that is hooked onto the hook of the crane. When in use, the pull ring 203 is hooked onto the hook of the crane for easy disassembly.

[0036] Working principle: When in use, place pulley 1 on top of electromagnet 3 so that cover plate 103 can cover the top of electromagnet body 301 and proximity switch body 401. Then start electromagnet 3 and proximity switch 4. Next, connect pull rope 2 to heavy frame 6 and trolley respectively. Finally, start trolley. The trolley pulls pull rope 2 upward, and pull rope 2 pulls heavy frame 6 horizontally.

[0037] If, during use, the connection between the electromagnet 3 and the cover plate 103 is not secure, causing the cover plate 103 to separate from the electromagnet 3, when the cover plate 103 leaves the ground, the distance between the cover plate 103 and the ground and the proximity switch 4 increases beyond the preset value. The proximity switch 4 will send a signal to stop the vehicle in time and activate the buzzer alarm 7 to remind the staff to deal with the problem in time.
