Description

[0002] The wire rope replacement operation of the winch-type gate hoist has long been carried out manually, and the operator needs to endure high-intensity physical labor, such as overcoming the weight and friction of the wire rope to perform operations such as disassembly, winding, and tightening. This process is not only labor-intensive, but also accompanied by significant safety risks. Since the operation is often carried out at high altitudes, the operator faces the risk of falling; at the same time, when handling the wire rope, it is susceptible to mechanical injuries such as rope breakage, rebound or drum rotation; the use of cutting and tightening tools may also cause operational errors. In addition, manual replacement is inefficient and time-consuming, resulting in increased equipment downtime, and it is highly dependent on the operator's skills and experience, making it difficult to maintain consistent work quality.

[0003] When replacing the wire rope of the existing winch-type hoist, an external guide wheel is usually used to guide the direction of the wire rope. However, in actual operation, these external guide wheels often cannot provide an ideal guiding effect, especially during the replacement process, the wire rope is prone to fall off or deflection, affecting the accuracy and efficiency of the replacement. Due to the limitations of the external guide wheel, the wire rope may not be able to maintain a stable path during the replacement process, which not only increases the difficulty of operation, but may also cause damage to the wire rope and even endanger the safety of the operator.

[0037] Driving wheels 602 and steering wheels 604: At least two driving wheels 602 are provided at one end of the mobile trolley 6 to provide power; at least two steering wheels 604 are provided at the other end to ensure that the device can flexibly turn. This design allows the replacement device to move freely in the working area to meet the replacement needs of different locations.

[0038] The wire rope replacement device 5 is connected to the rope release shaft of the winch 8, and drives the rope drum to rotate through the hydraulic motor 502 to recover the old wire rope on the winch 8.

[0039] After the recovery is completed, the wire rope drum 2 on the wire rope reversing device 1 carried by the mobile trolley 6 is connected to the wire rope replacement device 5, and the old wire rope is orderly wound on the rotating rope drum 501. Then a brand new wire rope is replaced on the winch 8 to complete the replacement process.

[0040] In the preferred embodiment, the steering wheel 604 is rotatably connected to the rotating seat 605, the rotating seat 605 is vertically rotatably connected to the trolley frame, the two rotating seats 605 are connected by a support rod 606, the end of the support rod 606 is rotatably connected to the rotating seat 605, a first support rod extending out is provided on one side of the rotating seat 605, the ends of the two first support rods are hinged to the two ends of the synchronization rod 607, a rotating telescopic rod 608 is provided on the support rod 606, the cylinder of the rotating telescopic rod 608 is hinged to the support rod 606, and the other telescopic end is hinged to the second support rod extending out from the other side of the rotating seat 605;

[0041] The mobile trolley 6 is provided with hydraulic legs 609 all around. The turning movement of the whole trolley is realized by rotating the telescopic rod 608.

[0042] In the preferred embodiment, a battery pack 603 is provided inside the mobile cart 6, and the battery pack 603 is electrically connected to the second drive motor 601 of the drive wheel 602 through a control system. A wireless receiving device is provided inside the control system, and an infinite remote control controls the movement and steering of the mobile cart 6; the second drive motor 601 is connected to the drive wheel 602 through a gear box.

[0043] The operator uses a wireless remote controller to control the mobile trolley 6 to move to a designated position next to the winch 8, and is ready to replace the wire rope.

[0044] Connect the old wire rope end on the rope-releasing shaft 802 of the winch 8 to the wire rope replacement device 5, ensuring that the connection is firm and without any obstacles.

[0045] The wire rope replacement device 5 is started, and the rope drum 501 is driven to rotate by the hydraulic motor 502 to wind the old wire rope on the hoist 8 onto the rope drum of the wire rope replacement device 5. This process is controlled by the operator through a wireless remote control to ensure the smooth recovery of the old wire rope.

[0046] During the process of recycling old wire ropes, the operator needs to continuously monitor the entire operation process and, if necessary, fine-tune the position of the mobile trolley or the operation of the wire rope replacement device through the wireless remote control to ensure the safety and efficiency of the replacement process.

[0047] In the preferred embodiment, a power friction wheel 4 is provided below both sides of the wire rope rewinding device 1. One end of the first bracket 401 of the power friction wheel 4 is hinged to the bottom plate of the automatic trolley 10, and the other end is hinged to the telescopic end of the first hydraulic cylinder 402.

[0048] The first driving motor 405 is connected to the first friction wheel 404 to provide power to make it rotate, and then the old wire rope drum 2 is driven to rotate through friction to retract and release the old wire rope.

[0049] By extending and retracting the first hydraulic cylinder 402, the pressure of the power friction wheel 4 on the old wire rope drum 2 can be adjusted to ensure sufficient friction force to drive the wire rope drum to rotate.

[0050] The articulated design of the first hydraulic cylinder 402 and the first bracket 401 enables the power friction wheel 4 to automatically adjust its height according to the change in the diameter of the old wire rope drum 2, ensuring that the friction wheel 4 always maintains contact with the wire rope drum and does not lose friction even when the wire rope is gradually reeled up.

[0051] Each powered friction wheel 4 has its own first drive motor 405, which means that the speed and torque of each friction wheel can be controlled independently, which is very useful for handling unbalanced loads or adjusting speed during changeover.

[0052] In the preferred embodiment, the wire rope reel device 1 includes two relative mobile support seats 101 and a fixed support seat 102. The wire rope drum is arranged on an installation shaft seat 103 between the mobile support seat 101 and the fixed support seat 102. The bottom of the mobile support seat 101 is slidingly connected to the bottom plate of the mobile trolley 6. A third drive motor 104 is also provided at one end of the mobile support seat 101. The screw 105 of the third drive motor 104 is threadedly connected to the nut inside the mobile support seat 101.

[0053] The mobile support base 101 and the fixed support base 102 device comprises a pair of mobile support bases 101 and a fixed support base 102, which support the wire rope drum together. The mobile support base 101 can slide on the bottom plate of the automatic trolley 10 to adapt to different wire rope drum sizes or replacement requirements.

[0054] The mounting shaft seat 103 is located between the movable support seat 101 and the fixed support seat 102, and is used to install and fix the wire rope drum to ensure its stable rotation during the replacement process.

[0055] The third driving motor 104 is disposed at one end of the movable support base 101 and is used to drive the movable support base 101 to slide along the bottom plate of the movable trolley 6 to achieve automatic positioning or adjustment of the wire rope drum.

[0056] The screw 105 is connected to the third driving motor 104 , and through the threaded connection with the inner nut of the movable support base 101 , the rotational motion of the motor is converted into linear motion, thereby accurately controlling the position of the movable support base 101 .

[0057] Example 2

[0058] Further illustrate with reference to Example 1, Figure 1-4 In the structure shown, in the preferred embodiment, a guide mechanism mounting groove 803 is provided between the rope collecting shaft 801 and the rope releasing shaft 802 of the winch 8, and a plurality of threaded holes are provided inside the guide mechanism mounting groove 803. At least two guide mechanisms 9 are arranged in the threaded holes inside the guide mechanism mounting groove 803 through a plurality of mounting screws 902, and the wire rope passes through the two guide mechanisms 9 and is connected to the rope collecting shaft 801 or the rope releasing shaft 802.

[0059] Located between the rope collecting shaft 801 and the rope releasing shaft 802 of the hoist 8, it is designed to accommodate and fix the guide mechanism 9. A plurality of threaded holes are provided in the mounting groove for installing the guide mechanism.

[0060] The guide mechanism 9 ensures that the steel wire rope travels along a predetermined path during the replacement process, avoids confusion or crossing of the rope during the retraction and release process, and keeps the rope neat and orderly.

[0061] Correct guidance not only improves the efficiency of the replacement process, but also reduces potential safety risks caused by rope misalignment or jamming, ensuring that the replacement operation proceeds smoothly.

[0062] In the preferred embodiment, the guide mechanism 9 includes a main guide wheel 901 , two small guide wheels are symmetrically arranged below the main guide wheel 901 , and a plurality of clamping guide wheel groups 903 and anti-breaking guide wheel groups 906 are arranged on one side of the main guide wheel 901 .

[0063] In the preferred solution, the structure of the compression guide wheel group 903 is as follows: two groups of guide wheels, one group of guide wheels has at least two guide wheels, a compression seat 904 is provided in the middle of the compression guide wheel group 903, screws pass through the compression seat 904 and are locked on the frame of the compression guide wheel group 903, a circular groove is provided between the compression seat 904 and the frame of the compression guide wheel group 903, and a cylindrical hole with a circular hole structure is formed; it is composed of two groups of guide wheels, each group contains at least two guide wheels, and a compression seat 904 is provided in the middle. The compression seat is locked on the frame by screws, and the cylindrical hole formed between the compression seat and the guide wheel group is used for guiding and compressing the wire rope.

[0064] The structure of the anti-pull-off guide wheel group 906 is: two sets of guide wheels, one set of guide wheels has at least two guide wheels, and an anti-drop-off seat 905 is provided in the middle of the anti-pull-off guide wheel group 906. The screw passes through the anti-drop-off seat 905 and is locked on the frame of the anti-pull-off guide wheel group 906. The anti-drop-off seat 905 and the frame are provided with a conical groove to form a conical hole of a conical structure.

[0065] It is also composed of two sets of guide wheels, each set contains at least two guide wheels, and an anti-drop seat 905 is arranged in the middle. The screw passes through the anti-drop seat and is locked on the frame. The tapered hole design formed between the anti-drop seat and the frame not only provides a guiding function, but also helps control or stop the movement of the wire rope when necessary to prevent accidental drop-off.

[0066] The conical hole shrinks in the opposite direction of the wire rope. The design of the conical hole helps to evenly distribute the stress on the wire rope and prevent local stress concentration. When the wire rope is stressed, the shape of the conical hole can make the force more evenly distributed along the length of the wire rope, reducing the risk of local fatigue and fracture.

[0067] The tapered hole not only provides a physical restraint, but also acts as a guiding mechanism, ensuring that the wire rope moves along the preset path.

[0068] The structural design of the tapered hole makes the hole diameter gradually decrease from the entrance to the exit. When the wire rope passes through, the hole wall exerts a progressive restraining force on the rope. This design can effectively prevent the wire rope from suddenly slipping or breaking under external impact or gravity.
