Specific embodiments

[0030] As Figures 1-4 shown, a fixing device for overhauling the steel wire rope of a ship lift counterweight system includes a first bracket 1, a second bracket 2, a locking device 3, and a support beam 4. The first bracket 1 is installed on the first pulley support 8, and the second bracket 2 is installed on the second pulley support 9. The first bracket 1 and the second bracket 2 are used to hold the steel wire rope 6 taken out from the rope groove of the pulley assembly 5. Here, there are two groups of the first brackets 1 and multiple groups of the second brackets 2. The overhaul of the eight groups of pulleys is not carried out simultaneously. During actual overhaul, after one pulley of the pulley group is overhauled and reset, another pulley is overhauled until the overhaul of the eight groups of pulleys is completed.

[0031] During disassembly, upper and lower sets of locking devices 3 are arranged on each steel wire rope on both sides of the pulley assembly 5 to be disassembled. Among them, the upper locking device 3 is used for lifting the steel wire rope, and the lower locking device 3 is located on the support beam 4 and is used to bear the self-weight of the steel wire rope. The support beam 4 is installed on the load-bearing beam 7 of the lifting hole.

[0032] As Figures 5-6 shown, the first bracket 1 includes an arc groove one 101, an arc groove support one 102, a transverse card slot one 103, a connecting plate one 104, and a longitudinal card slot 105. The arc groove one 101 is fixed above the arc groove support one 102.

[0033] The two sets of transverse card slots one 103 are located on the lower end face of the arc groove support one 102, and the transverse card slots one 103 are fixed by the connecting plate one 104. The two sets of longitudinal card slots 105 are fixedly connected to the transverse card slots one 103 through external rib plates. The first bracket 1 can be inserted into the pulley support one 8 through the transverse card slots one 103 and the longitudinal card slots 105 and realize its own stable support and limit through the pulley support one 8.

[0034] Preferably, a rubber pad is embedded in the arc groove one 101 for placing and supporting the steel wire rope 6.

[0035] As Figure 7 shown, the second bracket 2 includes an arc groove two 201, an arc groove support two 202, a transverse card slot two 203, and a connecting plate two 204. The arc groove two 201 is fixed above the arc groove support two 202. The two sets of transverse card slots two 203 are located on the lower end face of the arc groove support two 202. The transverse card slots two 203 are fixedly connected to the arc groove support two 202 through external rib plates, and the two transverse card slots two 203 are fixed by the connecting plate one 104. The second bracket 2 is inserted into the pulley support two 9 through the two transverse card slots two 203 on the left and right and realizes its own stable support and limit.

[0036] As Figures 10-11 shown, the locking device 3 includes a left clamping sleeve 301, a right clamping sleeve 302, a wedge block 303, a lifting lug 304, and a locking screw 305. One side of the left clamping sleeve 301 and the right clamping sleeve 302 is hinged by a pin shaft and can rotate and open and close along the axis of the pin shaft. The other side of the left clamping sleeve 301 and the right clamping sleeve 302 is closed and locked by a bolt. Vertical guide grooves are machined on the inner walls of the left clamping sleeve 301 and the right clamping sleeve 302. The two wedge blocks 303 move up and down along the guide grooves. The outer side wall of the wedge block 303 matches the inner arc surface of the corresponding left clamping sleeve 301 or right clamping sleeve 302. The inner side of the wedge block 303 is a conical surface. The conical holes formed by the two conical surfaces of the left and right wedge blocks 303 have the small-diameter side facing downwards. The locking screw 305 is vertically threadedly connected to the wedge block 303.

[0037] The locking screw 305 first passes through the U-shaped through hole of the wedge block 303, and then is assembled with the threaded holes in the left clamping sleeve 301 and the right clamping sleeve 302. By adjusting the locking screw 305, the arc surfaces of the left clamping sleeve 301 and the right clamping sleeve 302 are brought into contact with and pressed against the steel wire rope.

[0038] By rotating the locking screw 305, the wedge block 303 can move up and down relative to the left clamping sleeve 301 or the right clamping sleeve 302. Since the left and right wedge blocks 303 form a conical hole, the clamping force between the wedge block 303 and the steel wire rope 6 can be adjusted by driving the wedge block 303 to move up and down through the locking screw 305, realizing the locking and loosening of the locking device 3 and the steel wire rope 6.

[0039] Preferably, the wedge block 303 is embedded with a nylon coating for increasing the contact friction force of the steel wire rope and protecting the steel wire rope 6 from rigid extrusion. The lug 304 is used for lifting the steel wire rope.

[0040] The support beam 4 includes a left support beam 401, a right support beam 402, a pin 403 and a support plate 404. On both the left and right sides of the opposite sides of the left support beam 401 and the right support beam 402, there are ear plates with holes. The left support beam 401 and the right support beam 402 are detachably connected by two pins 403. The support plate 404 is correspondingly fixed on the upper end surface of the left support beam 401 or the right support beam 402. A hole diameter structure is formed at the center of the two support plates 404, and its hole diameter ensures that the steel wire rope can pass freely and restricts the locking device 3 from passing through.

[0041] Working principle and process:

[0042] 1). First, the support beam 4 is installed and arranged on the load-bearing beam of the lifting hole, so that the steel wire ropes on both sides of the pulley of the pulley assembly 5 pass through the center of the support beam 4.

[0043] 2). Secondly, upper and lower groups of locking devices 3 are installed on the two steel wire ropes on each side of the pulley assembly 5, and the locking of the locking device 3 and the steel wire rope 6 is realized by adjusting the locking screw 305; the lower group of locking devices 3 is placed on the support plate 404 of the support beam 4 for bearing the self-weight of the steel wire rope 6.

[0044] 3). The overhaul bridge crane hook is connected to the upper group of locking devices 3 on the steel wire ropes 6 on both sides of the pulley assembly 5, and the overhaul bridge crane can bear the self-weight of the steel wire rope in the pulley groove of the pulley assembly 5.

[0045] 4), Secondly, the relative positions of the two wire ropes 6 and the pulley grooves of the pulley assembly 5 are adjusted in real time through the main and auxiliary hooks of the maintenance gantry crane. The two wire ropes 6 that have come out of the groove section of the pulley assembly 5 are respectively operated into the arc grooves in the first bracket 1 and the second bracket 2. The hook of the maintenance gantry crane is disengaged from the locking device 3, so that the wire ropes 6 are completely separated from the pulley assembly 5. The wire ropes 6 are jointly fixed and supported by the locking device 3, the first bracket 1 and the second bracket 2, and finally the maintenance and fixation of the wire ropes 6 are realized.
