Problems solved by technology

The cumulative error of the long-term operation of the ship lift and the disassembly process of the safety mechanism need to adjust the clearance of the thread pair of the safety mechanism. At present, when adjusting the clearance of the safety mechanism, the operation process is complicated, the operation space is small, and many people are required to operate. There are dangers that seriously affect the safety and efficiency of the gap adjustment of the safety mechanism of the ship lift

Embodiment 1

[0046] The preferred solution is as Figure 1 to Figure 4 As shown, a clearance adjustment device for a ship lift safety mechanism includes a shaft coupling 1 and a driving device 2. The shaft coupling 1 includes a lower swivel support disc 11, a connecting shaft 12 and a hoop 13. The lower swivel support disc 11 is connected to The shaft 12 is coaxially connected, and the hoop 13 is used to connect the lower revolving support disc 11 with the upper revolving support disc 3 of the drive shaft of the safety mechanism. The driving device 2 is used to drive the connecting shaft 12 to rotate, thereby rotating the upper revolving support disc 3 .

[0047] Further, as figure 2 As shown, the lower swivel support disc 11 is a ring structure with splines, and the ring structure with splines is used to engage with the spline ring structure of the upper swivel support disc 3 .

[0048] Further, as image 3 As shown, the hoop 13 includes two arc-shaped fixing groove plates 13.1, and t...

Embodiment 2

[0059] In a preferred solution, the method for adjusting the clearance of the safety mechanism of the ship lift includes the following steps:

[0060] Step 1), disconnect the connection between the drive point reducer and the synchronous shaft that needs to be adjusted, adjust the attitude of the ship to the level, and reinstall the synchronous shaft;

[0061] Step 2), respectively measuring the upper clearance of the threaded pair of the safety mechanism and the lower clearance of the threaded pair of the safety mechanism to determine the adjustment direction of the clearance;

[0062] Step 3), remove the universal coupling driven by the safety mechanism, engage the lower rotary support plate 11 of the safety mechanism turning device with the upper rotary support plate 3 in alignment, and use the hoop 13 to connect the lower rotary support plate 11 and the upper rotary support plate 3 clamping;

[0063] Step 4), use the device to rotate the safety mechanism clockwise or coun...

Embodiment 3

[0068] Such as Figure 5 to Figure 7 As shown, the long nut-short screw type safety mechanism is a type of safety guarantee mechanism of the ship lift. During the lifting process of the cabin, the rotating screw goes up and down synchronously with the pinion of the driving mechanism. Contact, there is a certain gap between the two in the upper and lower directions during installation, that is, there is an upper gap between the safety mechanism thread pair and a lower gap between the safety mechanism thread pair. The full balance of the ship’s cabin is destroyed, which causes the gap between the screw threads of the safety mechanism to become smaller until the gap disappears completely, and the unbalanced load of the ship’s box is transmitted to the nut column through the screw rod, so as to prevent disasters caused when the full balance of the ship lift is destroyed sex accident.

[0069] The currently known safety mechanism installation methods are mainly aimed at the constru...

Abstract

The invention discloses a ship lift safety mechanism gap adjusting device and an adjusting method thereof. The ship lift safety mechanism gap adjusting device comprises a coupler and a driving device,the coupler comprises a lower rotary supporting disc, a connecting shaft and a hoop, the lower rotary supporting disc is coaxially connected with the connecting shaft, and the hoop is used for connecting the lower rotary supporting disc with an upper rotary supporting disc of a safety mechanism driving shaft. The device has a reversing function through a bidirectional ratchet wrench; rapid adjustment of the upper gap of the safety mechanism thread pair and the lower gap of the safety mechanism thread pair is achieved, adjustment is accurate, installation and maintenance are convenient, heightdata of gap adjustment can be accurately obtained through angle scales on the ratchet wheel and a position pointer on the handle, and the accuracy and the efficiency of safety mechanism gap adjustment are improved.

Description

technical field [0001] The invention belongs to the technical field of clearance adjustment of a safety mechanism of a ship lift, and in particular relates to a clearance adjustment device and an adjustment method for a safety mechanism of a ship lift. Background technique [0002] The safety mechanism is the safety guarantee mechanism of the ship lift, such as Figure 5 to Figure 7 As shown, during the lifting process of the cabin, the rotating screw moves up and down synchronously with the pinion of the driving mechanism, and the thread does not contact the threaded surface of the nut column. There is a certain gap between the two in the upper and lower directions during installation. The cumulative error of the long-term operation of the ship lift and the disassembly and assembly process of the safety mechanism need to adjust the clearance of the thread pair of the safety mechanism. At present, when adjusting the clearance of the safety mechanism, the operation process is ...
