[0018] The preferred embodiments of the auxiliary hook group support device for replacing the steel wire rope of the head sheave are described in detail below with reference to the drawings.
[0019] Combining Figures 1-5 An auxiliary hook group support device for replacing the steel wire rope of the head sheave, comprising a bottom plate 10 and two supports 20 fixedly installed on the upper surface of the bottom plate 10.
[0020] Each of the supports 20 comprises a first vertical plate 21 and a second vertical plate 22 arranged oppositely, and the two supports 20 are arranged in a spaced distribution along the length direction of the first vertical plate 21 and the second vertical plate 22.
[0021] The hook group 30 comprises a pulley cover 31 with a movable pulley and a hook 32 hung on the bottom of the pulley cover 31.
[0022] The distance D between the first vertical plate 21 and the second vertical plate 22 of each of the supports 20 is less than the maximum width R of the pulley cover 31 in the radial direction.
[0023] The two supports 20 enclose a hook accommodating space 100 for accommodating the hook 32.
[0024] When replacing the steel wire rope of the head sheave, the hook group 30 of the head sheave is dropped, and the axis of the pulley cover 31 of the hook group 30 is kept consistent with the distribution direction of the two supports 20, so that the pulley cover 31 is dropped above the two supports 20. Since the distance between the first vertical plate 21 and the second vertical plate 22 of each support 20 is less than the maximum width of the pulley cover 31 in the radial direction, the horizontal cylindrical pulley cover 31 can be stably clamped between the first vertical plate 21 and the second vertical plate 22 of the two supports 20, and at the same time, the hook 32 of the hook group 30 is naturally accommodated in the hook accommodating space 100.
[0025] The hook group supporting device can be used as a storage rack of the hook group 30, and the hook group 30 is placed on the two supports 20, so that the hook group 30 is fixed, and the steel wire rope wound on the movable pulley can be conveniently replaced.
[0026] Further, in combination with Figures 1-5 , at least two rib strips 311 are distributed on the outer surface of the pulley cover 31 along the axial direction, and each rib strip 311 is arranged around the circumference of the pulley cover 31. A pair of positioning insertion grooves (211, 221) are formed on the upper surfaces of the first vertical plate 21 and the second vertical plate 22 of each support 20, and the bottom of the corresponding rib strip 311 is inserted into the positioning insertion grooves (211, 221). Due to the arrangement of the positioning insertion grooves (211, 221) and the insertion fit between the positioning insertion grooves (211, 221) and the corresponding rib strip 311, the fixing effect of the hook group 30 is improved, and accidental sliding of the hook group 30 due to external force is avoided. Of course, the hook group supporting device of the present application can also not be provided with the positioning insertion grooves (211, 221), but the fixing effect of the pulley group will be slightly deviated.
[0027] Further, as shown in Figure 1 , Figure 4 and Figure 5 , the first vertical plate 21 and the second vertical plate 22 are arranged in parallel. Of course, the first vertical plate 21 and the second vertical plate 22 can be but not limited to arranged in parallel.
[0028] Further, as shown in Figure 1 , Figure 4 and Figure 5 , the third vertical plate 23 is connected between the first vertical plate 21 and the second vertical plate 22. The bottom of the third vertical plate 23 is fixedly connected with the bottom plate 10. The arrangement of the third vertical plate 23 can improve the overall stability of the support 20. Preferably, as shown in Figure 1 , Figure 5The third vertical plate 23 is vertically arranged between the first vertical plate 21 and the second vertical plate 22.
[0029] The above is only the embodiment of the present application, and does not limit the patent range of the present application, and any equivalent process transformation or direct or indirect application in other related technical fields by using the content of the present application is also included in the patent protection range of the present application.
