In the process of use, since steel wire rope bears heavy load and wears for a long time, it needs to be replaced regularly to ensure the safe operation of equipment.

[0003] In the process of replacing steel wire rope of portal crane, the traditional method is to place new steel wire rope roll on a specially-made support. Then, the operator gradually pulls out the steel wire rope from the steel wire rope roll by hand or using mechanical equipment such as forklift, so as to install it on the hoist mechanism of the crane. In this process, since the weight of the steel wire rope roll is large and has a certain moment of inertia, it needs to overcome a large resistance when pulling out the steel wire rope. At the same time, the operator needs to accurately control the length of the pulled-out steel wire rope to ensure that the new steel wire rope can be accurately installed in place.

When the rotating shaft rotates, the edge of the wear plate can contact the steel wire wound on the steel wire rope roll. Since the wear plate is fixed to the rotating shaft, the rotation of the rotating shaft can drive the rotation of the wear plate. Therefore, when the steel wire is pulled out from the steel wire rope roll to a certain length, the rotation of the rotating shaft can drive the edge of the friction plate to contact the steel wire wound on the steel wire rope roll, and then the friction force can realize the braking of the steel wire rope roll, while avoiding the loose of the steel wire rope, improving the safety.

[0007] As a further improvement of the above-mentioned scheme, the rotating shaft is rotatably installed on the inclined support through fixing bases, and the fixing bases are provided in two and fixed with the two inclined supports of the support frame respectively.

Based on the embodiment in the patent, the other embodiment obtained by the ordinary skill in the art without making the creative labor all belongs to the range of patent protection.

[0021] As Figures 1 to 4 The utility model provides a kind of brake support for portal crane steel wire rope replacement, it mainly includes support frame and brake mechanism installed on support frame.

[0022] Support frame includes underframe 2 and support structure installed above underframe 2.Support frame 2 is the beam structure of horizontal arrangement, for providing stable support base.Support structure includes support column 3, two support columns 3 are respectively vertically installed in the two sides of underframe 2, forms the two side columns for supporting steel wire rope roll 1.To ensure the stability of support column 3, the two sides of each support column 3 are fixedly connected with underframe 2 by diagonal brace 4.Diagonal brace 4 is not only set to enhance the stability of overall structure, but also provides installation base for brake mechanism.

[0023] The brake mechanism is mounted on the diagonal brace 4. Specifically, in the embodiment, the brake mechanism comprises a rotating shaft 5 which is rotatably mounted on the diagonal brace 4 through two fixed seats 7, and the rotating shaft 5 can be manually controlled to rotate under the action of external force, and can be kept relatively fixed with the fixed seat by the friction between the rotating shaft 5 and the fixed seat (the friction between the rotating shaft 5 and the fixed seat is greater than the force exerted on the rotating shaft by the steel wire rope). The side of the fixed seat 7 in contact with the diagonal brace 4 is fixed with the diagonal brace by bolts, realizing detachable mounting of the brake mechanism, and the rotating shaft 5 penetrates the fixed seat 7. Such detachable connection facilitates the disassembly, maintenance and adjustment of the brake mechanism according to steel wire rope rollers 1 of different sizes.

[0024] On one side of the rotating shaft 5, a wear-resistant plate 6 is fixed. The edge of the wear-resistant plate 6 is designed to be in contact with the steel wire rope wound on the steel wire rope roller 1, so as to realize the braking effect. The material of the wear-resistant plate 6 is preferably an alloy material with high strength and wear resistance, so as to ensure the service life and braking effect. When braking is needed, the operator can manually rotate the rotating shaft 5 to make the edge of the wear-resistant plate 6 contact the rotating steel wire rope roller 1, so as to realize braking through friction.

[0025] In order to facilitate operation, the utility model further fixes a pull rod 8 at one end of the rotating shaft 5. The other end of the pull rod 8 is fixed with a handle 9, and the extension direction of the handle 9 is consistent with the extension direction of the rotating shaft 5. The operator can rotate the rotating shaft 5 by holding the handle 9 and applying force, so as to control the wear-resistant plate 6. Thus, the operation process is simplified, and the safety of operation is improved.

[0026] In addition, in order to more stably support the steel wire rope roller 1, mounting seats 10 are further arranged on both sides of the support frame. The bottom of the mounting seat 10 is fixedly connected with the support column 3, and the upper part of the mounting seat 10 is provided with a U-shaped notch. The steel wire rope roller 1 can be placed in the notches of the two mounting seats 10, and the U-shaped notches arranged on the mounting seats 10 can facilitate the placement of the steel wire rope roller 1, and realize stable support of the steel wire rope roller 1,

[0027] In specific use, first, the steel wire rope roller 1 is placed on the mounting seat 10 of the support frame, and then the steel wire rope is pulled out of the steel wire rope roller by manual or forklift. When braking is needed, the operator only needs to hold the handle 9 and rotate the rotating shaft 5 to make the wear-resistant plate 6 contact the steel wire rope roller 1. After braking, the operator can reversely rotate the rotating shaft 5 to make the wear-resistant plate 6 separate from the steel wire rope roller 1, so as to restore the free rotating state of the steel wire rope roller. The arrangement of the brake mechanism not only realizes the braking effect of the steel wire rope roller 1, but also improves the safety and convenience of operation. Therefore, by the above technical scheme, the utility model effectively solves the safety hidden trouble in the replacement of the steel wire rope of the portal crane in the prior art.
