[0025] Carrying state adjustment: when the staff needs to carry the equipment, the staff can adjust the carrying state of the equipment according to the actual situation. Figure 1The two auxiliary mechanisms 4 are shown, one of which is operated first, and the worker closes the electromagnet 11 so that it no longer attracts the first vertical rod 5, then twists the cylinder 13 to drive the threaded column 12 to rotate, allowing the threaded column 12 to separate from the threaded hole 14 on the second vertical rod 6, then rotates the movable rod 8 hinged through the hinge seat 7 to rotate 90 degrees, in order to prevent the movable rod 8 from rotating, the movable rod 8 needs to be held, and the sliding block 10 is controlled to slide on the sliding groove 9 to extend into the groove in the first vertical rod 5, the movable rod 8 is provided with a control button, the button is pressed to start the electromagnet 11 to attract the inner wall of the groove, then the cylinder 13 is twisted again until it cannot be twisted any more, and the end of the cylinder 13 is in contact with the movable rod 8, and the other auxiliary mechanism 4 is adjusted in the same way, at this time, the total height of the movable rod 8 and the first vertical rod 5 is suitable for most adult workers, and the worker can push the equipment without bending over too much, the worker holds the cylinder 13 to push the equipment, and cooperates with the pulley mechanism 3 at the bottom of the bottom plate 1 to move the equipment, which is convenient to carry;

[0026] If the device cannot move smoothly on the road, the worker twists the cylinder 13 to separate the threaded column 12 from the movable rod 8, turns off the electromagnet 11 through the control button so that it no longer attracts the groove, pushes the sliding block 10 to separate it from the sliding groove 9, and rotates the movable rod 8 to abut against the second vertical rod 6, at this time, the positions of the threaded holes 14 on the two second vertical rods 6 match, the threaded column 12 is screwed in to connect the two, and the cylinder 13 is twisted to abut against the movable rod 8, the sliding block 10 is pushed to make the electromagnet 11 on the sliding block 10 contact the first vertical rod 5, the electromagnet 11 is started to attract the first vertical rod 5, and the worker can hold the movable rod 8 with both hands to lift the device as a whole, which is convenient to carry;

[0027] The first vertical rod 5 and the second vertical rod 6 in the structure are made of martensitic stainless steel, so that the electromagnet 11 can attract the first vertical rod 5, the surface of the martensitic stainless steel is provided with a corrosion-resistant coating to avoid rust and corrosion of the device under harsh conditions, and the corrosion-resistant coating does not affect the attraction effect of the electromagnet, the device is small and the total weight is about 20 kg, which can be lifted by an adult worker, the hinge seat 7 in the text is composed of a frame and a cylinder 13, and the movable rod 8 is sleeved on the outer wall of the cylinder 13 and can rotate around the cylinder 13, the components on the auxiliary mechanism 4 are made of high-strength martensitic stainless steel to avoid breakage of the components when the worker lifts the device, in addition, the sliding block 10 and the sliding groove 9 in the text are T-shaped structures;

[0028] Device working state: when the device is working, the brake assembly on the pulley mechanism 3 can fix the pulley, ensuring that the device can be stably placed in the designated area. The device is equipped with a power cord that can be connected to external power supply for power supply, and the length of the power cord is sufficient enough to avoid insufficient length.

[0029] The instruction manual in the structure clearly indicates that after using the device in a humid and dusty environment, the T-shaped sliding block 10 and the sliding groove 9 need to be cleaned in time. The specific maintenance method may include using special cleaning tools such as small brushes or compressed air guns to remove accumulated dirt. At the same time, the manual will suggest regularly applying an appropriate amount of protective oil to the surface of the sliding block 10 and the sliding groove 9 to form a protective film, which can not only reduce dirt adhesion but also ensure smooth sliding. In addition, it will also remind the operator to place the device in a dry and clean environment during idle period to reduce the risk of dirt accumulation. The electromagnet 11 may experience a decrease in magnetic properties and unstable adsorption if used frequently. The instruction manual will develop a strict maintenance and detection plan, requiring the operator to regularly check the adsorption performance of the electromagnet 11. This can be done through a simple adsorption test, such as using a standard weight iron block to test whether the adsorption force of the electromagnet 11 meets the standard. At the same time, the manual will explain the service life and expected magnetic decay period of the electromagnet 11. When a certain number of uses or time is reached, the electromagnet 11 should be replaced in time. During routine maintenance, the surface of the electromagnet 11 should be kept clean to avoid impurities affecting the adsorption effect. If the electromagnet 11 is found to be unstable in adsorption, the device should be immediately stopped for repair or replacement to ensure the stability and safety of the device.

[0030] Replacing electromagnet 11: The connection part of electromagnet 11 and sliding block 10 is made of martensitic stainless steel, and the bottom of electromagnet 11 is designed with a strong magnetic attraction device. During normal operation, electromagnet 11 is tightly adsorbed on sliding block 10 through magnetic force to ensure stable connection. When disassembling, a special demagnetizing tool such as a small handheld demagnetizer is used to demagnetize the magnetic attraction device at the bottom of electromagnet 11, making its magnetic force disappear, so that electromagnet 11 can be easily removed from sliding block 10. Magnetic attraction type electrical connectors are installed at the end of electromagnet 11 and the connection cable respectively. Multiple metal contacts are arranged inside the connector to tightly fit the contacts through magnetic force, achieving stable electrical connection. When disassembling, electromagnet 11 and the cable can be pulled apart, and the magnetic attraction type connector will separate, avoiding the problem of damage to the contacts due to excessive plug-in force or difficulty in plugging due to interface aging in traditional plug-in interfaces.

[0031] In the embodiment, in order to significantly improve the overall stability of the device, the two auxiliary mechanisms 4 are symmetrically arranged, which can make the device more uniform in stress during use, effectively reduce the shaking or tilting phenomenon caused by uneven stress, and ensure that the device can operate stably under various working conditions, thereby providing a solid guarantee for the smooth operation of the anchor cable tensioning operation.

[0032] In the embodiment, the safety of the operator during operation is fully considered, and the anti-skid layer is arranged on the outer wall of the cylinder 13 to effectively avoid the slipping phenomenon when the operator's hand contacts the cylinder 13. The anti-skid layer is tightly connected with the outer wall of the cylinder 13 by a firm fixing manner, which can significantly increase the friction between the hand and the cylinder 13, and ensure the stability and reliability of the operation process.

[0033] In the embodiment, in order to further improve the anti-skid performance, a plurality of anti-skid lines are additionally arranged outside the anti-skid layer. The anti-skid lines are carefully designed according to the ergonomics and friction principle, and are uniformly distributed on the surface of the anti-skid layer. They can effectively increase the friction between the hand and the anti-skid layer, significantly improve the anti-skid effect even in wet or slippery environment, and ensure the operation safety.

[0034] In the embodiment, improving the stability of the device is a key factor, and based on this, a plurality of pulley mechanisms 3 are symmetrically arranged. This arrangement makes the support force in each direction more balanced during movement, effectively reduces the shaking and tilting problem caused by uneven stress, and ensures that the device can operate stably on flat ground or slightly undulating road surface.

[0035] In the embodiment, in order to enhance the connection stability between the components and ensure the reliability of the device during use, the first vertical rod 5, the second vertical rod 6 and the bottom plate 1 are connected by welding. The welding process can tightly combine the first vertical rod 5 and the second vertical rod 6 with the bottom plate 1, effectively improve the connection strength, avoid loosening and displacement caused by loose connection, ensure the stability of the overall structure of the device, and meet the high-strength use requirement of the anchor cable tensioning operation.

[0036] The sizes of all components in the structure are not specifically limited here and need to be produced according to the actual situation. The control mode of the utility model is controlled by manually starting and closing the switch. The wiring diagram of the power element and the power supply belong to the common knowledge in the art. And the utility model is mainly used for protecting mechanical devices, so the control mode and wiring arrangement of the utility model will not be explained in detail.
