[0002] Cranes, elevators and other lifting and conveying equipment rely on the lifting of wire ropes to transport materials and personnel. As the most common electromechanical equipment in industry, lifting and conveying equipment is widely used in equipment manufacturing, transportation and logistics, water conservancy and hydropower construction, nuclear power construction and other pillar industries of the national economy.

[0003] During the use of lifting and conveying machinery and equipment, the wire rope, as a force-bearing component, may rub against surrounding equipment, structures and other objects, or the wire rope may be out of the groove, resulting in wire breakage, broken strands and other defects. As the lifting force-bearing component of the lifting and conveying machinery and equipment, the wire rope must ensure that its tensile stress is within the range required by the technical specifications. When the wire rope breaks, it must be replaced. Because most lifting and conveying equipment has a high lifting height, the wire rope is wound around the drum, fixed pulley and movable pulley, so when replacing the wire rope, the old wire rope must be removed from the three mechanisms and then the new wire rope must be inserted. In the prior art, the wire rope reel device of the lifting and conveying equipment cannot be moved and is not suitable for different environments and equipment. Summary of the invention

[0025] Description of the drawings: 1. ratchet wrench; 2. support component; 3. handle; 4. stud; 5. angle bracket; 6. pulley; DETAILED DESCRIPTION

[0026] The technical solution of the present invention is described clearly and completely below in conjunction with the accompanying drawings and specific implementation methods. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] like Figures 1 to 5 As shown, the present invention proposes a reel stand for replacing the wire rope of lifting and conveying equipment, the device includes a bracket 5, a supporting component 2, a stud 4, a ratchet wrench 1 and a handle 3, the bracket 5 is provided with three legs, a pulley 6 is provided under the bracket 5, a locking structure is provided on the pulley 6, and the pulley 6 is used to move and fix the device; a threaded cylindrical hole is provided in the center of the bracket 5, and a stud 4 is provided in the cylindrical hole.

[0028] The upper end of the stud 4 is connected to the support component 2, and a rolling support shaft is arranged inside the support component 2. The top of the support component 2 is a semicircular structure. The semicircular support component 2 cooperates with the rolling support shaft. The rolling support shaft is placed on the semicircular support component 2 of the left and right stands for rotational movement. The support shaft is provided with a wire rope drum, and the step of taking up or releasing the wire rope is achieved by rolling the drum. The rolling shaft may jump when the drum rolls. Designing the support component 2 into a semicircle can well prevent the rolling shaft from jumping out of the support semicircle, and avoid the situation where the rolling shaft jumps out during the replacement of the wire rope, and the drum and the rolling shaft need to be lifted and restored to the support component 2. The drum and the wire rope are of large mass, and this situation needs to be avoided as much as possible. The semicircular support component 2 also facilitates the placement of the reel and the rolling support shaft. If it is designed as a hollow cylindrical support component 2, after lifting the reel and the rolling support shaft, the support shaft needs to be inserted into the hollow cylindrical support component 2. The reel and the wire rope have a large mass, so this situation needs to be avoided as much as possible. Therefore, the support component 2 is designed to be semicircular, which is convenient for maintenance personnel to align the shaft with the support component 2, and the placement process is convenient and simple.

[0029] The middle section of the stud 4 is connected to the ratchet wrench 1, and the ratchet wrench 1 adopts a one-piece two-way pawl. The ratchet of the ratchet wrench 1 is connected to the stud 4 by a pin. A handle 3 is provided on the outside of the ratchet wrench 1. The pawl and the wrench are connected by a bolt at the front section of the handle 3. The spring base of the pawl and the wrench are an integrated structure. When the user rotates the handle 3, the pawl and the handle 3 act as one body and move at the same time. The ratchet and the stud 4 are integrated. Through the cooperation of the ratchet and the pawl, the horizontal movement of the handle 3 is converted into the vertical up and down movement of the stud 4.

[0030] like Figure 3 As shown, the ratchet wrench 1 is provided with a locking component, which is a cylindrical rod, and the cylindrical rod rotates on the ratchet wrench 1. When the cylindrical rod is rotated to position 1, as shown in FIG. Figure 4 As shown, the fixed spring fixed on the ratchet wrench 1 pushes up the pawl, so that the lower pawl is close to the ratchet, and the handle 3 of the ratchet wrench 1 is pushed counterclockwise, and the stud 4 will be lifted. When the cylindrical rod is rotated to position 2, as shown in FIG. Figure 5 As shown, the cylindrical rod will lock the lower pawl, so that the upper pawl is as close to the ratchet as possible, and the handle 3 of the ratchet wrench 1 is pushed clockwise, and the stud 4 will be lowered, thereby realizing the reversing function.

[0031] In some embodiments, the present invention provides a reeling method for replacing a reeling stand for a wire rope of a lifting and conveying equipment, the method comprising:

[0032] Step 1: Move the stand to a suitable position via the pulley 6 and lock the pulley 6;

[0033] Step 2: Turn the handle 3 to adjust the stud 4 to move up and down to adjust the height of the platform; when the height of the platform is appropriate, lock the ratchet wrench 1 through the locking component.

[0034] Step 3: Place a rolling support shaft in the support component 2, place a wire rope drum on the upper end of the rolling support shaft, and retract and release the wire rope by rotating the wire rope drum.

[0035] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
