DETAILED DESCRIPTION

[0035] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. The present invention is further described below in conjunction with the embodiments.

[0036] See also Figures 1-4 In one embodiment of the present application, a power cable pulling device for electromechanical use includes a base 1, a mounting platform 2, a winding roller 14, a controller 5, and a signal output 27. The mounting platform 2 is movably mounted on the base 1, the winding roller is movably mounted on the mounting platform 2, the controller 5 and the signal output 27 are both mounted on the mounting platform 2, and the cable pulling device further includes:

[0037] A locking structure is provided on the winding roller 14 and is used to fix the wire on the winding roller 14;

[0038] A suction cup 6 is provided on the base 1; and

[0039] The air extraction module is arranged on the mounting platform 2 and connected to the winding roller 14. When the winding roller 14 rotates, the air extraction module is controlled to work and the air pressure between the suction cup 6 and the supporting surface can be adjusted;

[0040] The air extraction module comprises:

[0041] A hollow tube 7 is provided on the mounting platform 2, and the hollow tube 7 is connected to the suction cup 6 through the organ pipe;

[0042] A piston 10 is movably disposed in the hollow tube 7 and elastically connected thereto; and

[0043] The transmission structure is provided between the piston 10 and the winding roller 14 . When the winding roller 14 rotates, the position of the piston 10 in the hollow tube 7 is adjusted by the transmission structure.

[0044] In a specific case of this embodiment, the transmission structure includes:

[0045] A slide rod 11 is movably mounted on the hollow tube 7 and threadedly engaged with the hollow tube 7, and one end of the slide rod 11 is movably connected to the piston 10; and

[0046] One end of the No. 1 drive shaft 12 is connected to the winding roller 14 , and the other end of the No. 1 drive shaft 12 is symmetrically provided with a group of No. 1 card strips 13 , and a No. 1 card slot that slides with the No. 1 card strip 13 is formed in the slide rod 11 .

[0047] In another specific case of this embodiment, a conductive block 9 and a resistor bar 8 are respectively provided on the piston 10 and the inner wall of the hollow tube 7 , and the resistor bar 8 is located on the moving path of the conductive block 9 .

[0048] It should be noted that the position of the piston 10 is not limited to being detected by the above-mentioned resistor bar 8 and conductive block 9, but can also be replaced by an infrared distance sensor or a laser distance sensor, which are not listed here one by one.

[0049] In actual application, the wire is attached to the outer wall of the winding roller 14, and the locking structure is controlled to fix the wire on the winding roller 14, and then the winding roller 14 is rotated to reel the wire. In the process of the winding roller 14 reeling the wire, the No. 1 drive shaft 12 can be driven to rotate. When the No. 1 drive shaft 12 rotates, the No. 1 card strip 13 and the No. 1 card slot cooperate to drive the piston 10 to move up along the hollow tube 7, thereby sucking the air between the suction cup 6 and the support surface into the hollow tube 7, completing the whole device adsorbed and fixed on the support surface. At the same time, the conductive block 9 moves synchronously with the piston 10, and the conductive block 9 contacts the resistor bar 8. The staff monitors the number of turns of the wire by the winding roller 14 based on the resistance value fed back by the signal output device 27. When the wire is straightened and tightened under the action of external force, the winding roller is driven to rotate a certain angle, and the piston 10 continues to move up along the hollow tube 7, thereby increasing the adsorption strength between the entire device and the support surface, ensuring the stability of the entire device. The staff can also remotely monitor the tension of the wire based on the change in resistance value.

[0050] See also Figure 1 、 Figure 3 as well as Figure 4 As another preferred embodiment of the present application, the locking structure includes:

[0051] The locking strip 20 is formed with a receiving groove 26 on the winding roller 14, and a wire groove 25 is formed in the receiving groove 26. The locking strip 20 is movably arranged in the receiving groove 26 and the two are elastically connected;

[0052] The connecting tube 21 is movably disposed in the winding roller 14 and the two are threadedly engaged;

[0053] A second drive shaft 22 is movably mounted on the winding roller 14 and has a second clamping strip 23 at one end thereof. A second clamping slot matching the second clamping strip 23 is provided in the connecting tube 21; and

[0054] The operating disk 24 is movably disposed in a groove formed in the winding roller 14 , and the operating disk 24 is connected to the other end of the second drive shaft 22 .

[0055] In a specific case of this embodiment, a wheel seat 15 is movably provided in the wire groove 25, and the wheel seat 15 is connected to the winding roller 14 through an elastic member. A roller 16 is movably provided on the wheel seat 15, and a No. 2 contact 19 and a No. 1 contact 18 are respectively provided on the wheel seat 15 and the winding roller 14, and the No. 1 contact 18 is located on the moving path of the No. 2 contact 19.

[0056] It should be noted that the elastic member can be a spring 17, a spring sheet or an elastic steel plate structure. In this embodiment, the elastic member is preferably a spring 17, and the spring 17 is connected between the wheel seat 15 and the winding roller 14. As for the specific model parameters of the spring 17, the best choice can be made according to actual conditions, and they are not listed here one by one.

[0057] During the installation of the wires, the staff passes the wires through the wire groove 25 and rotates the operating disk 24, thereby driving the No. 2 drive shaft 22 to rotate. Under the cooperation between the No. 2 card strip 23 and the No. 2 card groove, the connecting tube 21 is driven to rotate. Under the threaded cooperation between the connecting tube 21 and the winding roller 14, the locking strip 20 is driven to move toward the direction of the wire, thereby fixing the wire. At this time, the wire squeezes the roller 16, and the wheel seat 15 moves and makes the No. 1 contact 18 and the No. 2 contact 19 meet. Under the action of the signal outputter 27, the staff can understand the installation progress of the wire through the remote monitoring terminal. When the wire breaks and detaches from the winding roller 14, the roller 16 and the wheel seat 15 are reset, and the No. 1 contact 18 and the No. 2 contact 19 are disengaged, so that the signal outputter 27 can be used to feedback to the staff, so that the staff can make corresponding wire repair work as soon as possible.

[0058] See also Figure 1 As another preferred embodiment of the present application, the wire pulling device further includes an adjustment structure, which is arranged between the mounting platform 2 and the base 1 and is used to adjust the height of the mounting platform 2.

[0059] In this embodiment, the adjustment structure includes a power element and a threaded rod 3. The threaded rod 3 is movably arranged on the base 1 and threadedly engaged with the mounting platform 2. The power element is arranged on the base 1 and its output end is connected to the threaded rod 3.

[0060] It should be noted that the power element can be a stepper motor 4 or a servo motor. In this embodiment, the power element is preferably a stepper motor 4. The stepper motor 4 is arranged on the base 1 and its output end is connected to the threaded rod 3. As for the specific model parameters of the stepper motor 4, the best choice can be made according to actual conditions, and they are not listed here one by one.

[0061] In actual application, the controller 5 controls the stepper motor 4 to be powered on and rotated, driving the threaded rod 3 to rotate, so that under the action of the threaded cooperation between the threaded rod 3 and the mounting platform 2, the mounting platform 2 is driven to move in the vertical direction, thereby realizing the height adjustment of the mounting platform 2 and the winding roller 14, making it convenient for the entire device to adapt to different working environments.

[0062] How this application works:

[0063] In the process of installing the wires, the staff passes the wires through the wire groove 25, and rotates the operating disk 24, thereby driving the No. 2 drive shaft 22 to rotate. Under the cooperation between the No. 2 card strip 23 and the No. 2 card groove, the connecting tube 21 is driven to rotate. Under the threaded cooperation between the connecting tube 21 and the winding roller 14, the locking strip 20 is driven to move toward the direction of the wire, thereby fixing the wire. At this time, the wire squeezes the roller 16, and the wheel seat 15 moves and makes the No. 1 contact 18 and the No. 2 contact 19 meet. Under the action of the signal output device 27, the staff can understand the installation progress of the wire through the remote monitoring terminal, and then rotate the winding roller 14 to reel the wire. In the process of the winding roller 14 reeling in the wire, it can drive the No. 1 drive shaft 12 to rotate. When shaft 12 rotates, the interaction between the first clamping strip 13 and the first clamping slot drives piston 10 upward along hollow tube 7, thereby drawing air between suction cup 6 and the support surface into hollow tube 7, securing the entire device to the support surface. Simultaneously, conductive block 9 moves synchronously with piston 10, contacting resistor bar 8. Staff monitor the number of turns the wire has been wound by reel 14 based on the resistance value reported by signal output 27. When external force causes the wire to straighten and tighten, the reel rotates a certain angle, further allowing piston 10 to move upward along hollow tube 7, increasing the adhesion strength between the entire device and the support surface and ensuring overall stability. Staff can also remotely monitor the wire tension based on the change in resistance. If the wire breaks and breaks off reel 14, roller 16 and wheel seat 15 reset, disengaging contact between first contact 18 and second contact 19. This information is then fed back to staff via signal output 27, enabling immediate repair. The controller 5 controls the stepper motor 4 to be powered on and rotated, driving the threaded rod 3 to rotate, so that under the action of the threaded cooperation between the threaded rod 3 and the mounting platform 2, the mounting platform 2 is driven to move in the vertical direction, thereby realizing the height adjustment of the mounting platform 2 and the winding roller 14, making it convenient for the entire device to adapt to different working environments.

[0064] The above is a schematic description of the present invention and its embodiments, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by this and, without departing from the purpose of the present invention, designs a structure and embodiment similar to this technical solution without inventiveness, they shall fall within the scope of protection of the present invention.

[0065] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
