In addition, since the threading device 2 is usually in a high position and the user stands on the ground, considering that there is an alignment problem when the user aligns the threading device 2 with the hole of the hanging ring, it may be preferable to provide a guide part at the front end of the front housing 201, which may be a cone-shaped body with a relatively small front end for easy access into the hole of the hanging ring. Of course, in other embodiments, a camera may be preferentially installed at the front end of the front housing 201, and the camera is connected to a wireless transmission module for transmitting an image signal to the user mobile terminal, so that a user can align the hole of the hanging ring on the ground more accurately according to the image signal transmitted by the camera.
In addition, the housing further comprises a rear housing 203 connected with the other end of the main housing 202, the rear housing 203 is used for connecting with the shaft, considering that the thickness of the shaft may not be uniform, for example, some shafts are 6cm round pipes, and some shafts may be 8cm round pipes, in this case, only the rear housing 203 needs to be replaced, and the main housing 202 and the front housing 201 can be used commonly.
In the specific assembly, since the main housing 202 has a piston cavity and a drive shaft cavity, which all need to be installed with components, the main housing 202 includes a left half-shell 2021 and a right half-shell 2022, the left half-shell 2021 and the right half-shell 2022 are spliced and connected, so that the piston rod 22 and the drive shaft 24 can be conveniently assembled, the left half-shell 2021 and the right half-shell 2022 are completely installed and fastened by screws, and the left half-shell 2021 and the right half-shell 2022 are spliced and connected with the front housing 201 and the rear housing 203 integrally, which is equivalent to that the front housing 201 and the rear housing 203 also play a role in fixedly connecting the left half-shell 2021 and the right half-shell 2022, thereby further enhancing the connection stability between the left half-shell 2021 and the right half-shell 2022.
The operation method for hoisting the power equipment by using the embodiment is as follows:
s1, reasonably selecting the number of the unit rods according to the height of the hanging ring on site, and splicing and sleeving the unit rods to form a rod body matched with the height of the hanging ring;
s2, the threading device is righted, the force application plate is positioned below the threading device to open the locking and releasing mechanism, and the balancing weight is locked on the threading device;
s3, mounting the threading device on the sleeving section of the topmost unit rod, pulling out a part of the threading on the wire spool, and connecting the end of the threading to a balancing weight;
s4, lifting the threading equipment, aligning a balancing weight of the threading device with the hole of the hanging ring, enabling the balancing weight to pass through the hole of the hanging ring, and stopping after the balancing weight completely passes through the hole of the hanging ring;
s5, the force application plate is aligned to the hanging ring to be pressed down, so that the driving shaft rises, the locking and releasing mechanism releases the balancing weight, the balancing weight falls under the action of gravity, and threading is completed.
Example two:
the difference from the first embodiment is that the locking and releasing mechanism in this embodiment is different from the first embodiment in that the locking and releasing mechanism in this embodiment is an electromagnet disposed in the housing, and the electromagnet is located above the counterweight, and the operation method for hoisting the power equipment by using this embodiment is as follows:
s1, reasonably selecting the number of the unit rods according to the height of the hanging ring on site, and splicing and sleeving the unit rods to form a rod body matched with the height of the hanging ring;
s2, starting an electromagnet, and adsorbing the balancing weight on the threading device;
s3, mounting the threading device on the sleeving section of the topmost unit rod, pulling out a part of the threading on the wire spool, and connecting the end of the threading to a balancing weight;
s4, lifting the threading equipment, aligning a balancing weight of the threading device with the hole of the hanging ring, enabling the balancing weight to pass through the hole of the hanging ring, and stopping after the balancing weight completely passes through the hole of the hanging ring;
and S5, closing the electromagnet to enable the locking and releasing mechanism to release the balancing weight, and enabling the balancing weight to fall under the action of gravity, thereby completing threading.
