After the bearing is worn after long-term operation, the working attitude of the pulley unit will be inclined and deviated, affecting the safe and stable operation of the balance weight system. It is necessary to consider replacing the central bearing of the pulley. Affected by the overall structure of the balance weight system, the replacement cycle of the pulley unit is relatively long, and the pulley replacement operation can only be carried out during the annual navigation suspension and maintenance period. Before the arrival of the maintenance period, in order to ensure the normal operation of the pulley, it is necessary to correct its attitude. Content of the Utility Model

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present utility model and should not be construed as limiting the present utility model.

[0030] Please refer to Figures 1-7 , a two-way guiding and deviation correction device for a large balancing pulley unit of a vertical ship lift, comprising a guiding bracket 100 and a connecting bracket 200. The two guiding brackets 100 are arranged opposite to each other, and the two connecting brackets 200 are respectively connected to both ends between the two guiding brackets 100; the guiding bracket 100 includes a bottom plate 110 and two sliding grooves 120 provided on the bottom plate 110. A guiding block 130 is installed in the sliding groove 120, and one ends of the two guiding blocks 130 away from each other respectively extend out of the sliding groove 120.

[0031] The two guiding brackets 100 are installed on the outside of the permanent support 400 through the two connecting brackets 200. The guiding blocks 130 on the guiding brackets 100 abut against the rims of the pulley units 300 on both sides, so as to guide and correct the deviation of the pulley units 300 on both sides, solve the problem of the deviation of the working posture of the pulley, ensure that the pulley resumes the normal working posture, and continue to operate safely and stably.

[0032] In the present application, the function of the connecting bracket 200 is to fix the guiding bracket 100 to the permanent support 400, so the structure of the connecting bracket 200 is not limited.

[0033] Refer to Figure 4 , mounting holes 111 are respectively provided on both sides of the bottom plate 110, and the bottom plate 110 is bolted to the connecting bracket 200 through the mounting holes 111. It is convenient to detachably install the guiding bracket 100 and the connecting bracket 200 on the permanent support 400.

[0034] Refer to Figure 4 , ejector bolts 125 are respectively screwed on one side of the two sliding grooves 120 close to each other. The extending length of the guiding block 130 can be adjusted through the ejector bolts 125, and after the guiding block 130 is worn, the guiding block 130 can be adjusted through the ejector bolts 125 to keep the guiding block 130 abutting against the rim of the pulley unit 300.

[0035] Specifically, in Figure 4Among them, two sliding grooves 120 are respectively provided with two threaded holes 124 on the side close to each other, and a jacking bolt 125 is screwed on each threaded hole 124.

[0036] Furthermore, in the two sliding grooves 120, a baffle 140 is movably installed on the side where the jacking bolt 125 is located. The baffle 140 is made of steel plate to prevent the jacking bolt 125 from damaging the guiding block 130 when the jacking bolt 125 is tightened.

[0037] See Figure 3 、 4 As shown in, limit bolts 126 are respectively screwed on the tops of the two sliding grooves 120, and limit long holes 131 are provided at the positions of the guiding block 130 corresponding to the limit bolts 126. The limit bolts 126 extend into the limit long holes 131 to prevent the guiding block 130 from falling off the sliding groove 120 during transportation and installation.

[0038] In this embodiment, see Figure 4 、 5 The sliding groove 120 includes a first limiting plate 121, a second limiting plate 122 and an end plate 123. The first limiting plate 121 and the second limiting plate 122 are arranged oppositely, and the end plate 123 is connected to one end of the first limiting plate 121 and the second limiting plate 122; the guiding block 130 is installed between the first limiting plate 121 and the second limiting plate 122. Both the first limiting plate 121 and the second limiting plate 122 are L-shaped.

[0039] Furthermore, a rib plate 112 is provided on the lower side of the second limiting plate 122 and connected to the bottom plate 110, and the stability of the connection between the sliding groove 120 and the bottom plate 110 is improved by providing the rib plate 112.

[0040] Specifically, the guiding block 130 is a self-lubricating nylon block or a self-lubricating copper block.

[0041] See Figure 3 As shown in, an installation part 210 is provided at the bottom of the connection bracket 200. The installation part 210 is used to install expansion bolts, and the installation part 210 is fixed to the ground concrete foundation through the expansion bolts, so as to limit and fix the deviation correction device of the present application.

[0042] The working principle or action process of the present utility model is as follows:

[0043] See Figure 6 、 7 As shown in, the two connection brackets 200 and the two guiding brackets 100 surround the permanent support 400, and the guiding blocks 130 on the guiding brackets 100 abut against the rims of the two side pulley units 300, so as to guide and correct the deviation of the two side pulley units 300.

[0044] When installing a set of this guiding and deviation-correcting device, reverse guiding and deviation correction of two adjacent pulleys can be achieved, that is, the right pulley corrects deviation to the left, and the left pulley corrects deviation to the right. When two sets of guiding and deviation-correcting devices are installed on two adjacent base supports, the two-way guiding and deviation-correcting function of the pulley in the middle position can be achieved, that is, the left guiding block 130 corrects deviation to the right, and the right guiding block 130 corrects deviation to the left.
