SUMMARY

[0005] The purpose of the present application is to provide an anchoring and jacking method of a gantry loading and unloading crane, which can anchor the gantry crane on the deck of a ship when the gantry crane is not in use, and can jack up the crane to realize the inspection or maintenance of other equipment at the bottom of the crane, and the anchoring and jacking operation has good reliability.

[0006] To achieve the above object, the present application provides the following technical scheme: an anchoring jacking method of a gantry loading and unloading crane, which is realized by cooperation of an anchoring device and a jacking device, the anchoring device comprising an anchoring oil cylinder, an anchoring support and a locking assembly; the anchoring oil cylinder and the jacking device are fixed on the gantry crane through a mounting seat; comprising the following steps: S1, the gantry crane is stopped after sliding to a preset point on a track, the mounting seat is fixed and welded on the gantry crane, and then the jacking device and the anchoring oil cylinder are both fixed on the mounting seat; S2, the jacking device and the anchoring oil cylinder are driven to abut against a deck, and the first center point and the second center point after the jacking device and the anchoring oil cylinder contact the deck are marked respectively; S3, the center of the third through hole on the anchoring support is coincided with the second center point on the same vertical line, and the center of the first positioning hole on the anchoring support is coincided with the first center point on the same vertical line, then a welding point is marked on the support plate at the bottom of the anchoring support, and the anchoring support positioning is completed; S4, after welding on the welding point, the anchoring support is fixed on the deck, the anchoring oil cylinder drives the piston rod to extend downward along the vertical direction and penetrates through the third through hole to the bottom of the anchoring support, and then the piston rod is locked on the anchoring support through the locking assembly from the bottom of the anchoring support and penetrating through the piston rod; S5, the output end of the jacking device is driven to extend downward along the vertical direction and abut against the anchoring support, the jacking device and the anchoring oil cylinder are continuously driven to synchronously perform the downward extension action, the anchoring support supports the output end of the jacking device, and the jacking device generates a reverse force to jacking up the gantry crane.

[0007] The above method, since the gantry crane will slide back and forth on the track during the working process, and when the equipment at the bottom of the gantry crane needs to be detected or repaired, the gantry crane needs to be anchored at four points first, and then lifted up after being anchored at four points. In order to set a fixed anchoring point on the deck and make the gantry crane slide accurately to the anchoring point, the gantry crane is stopped after sliding to the preset point on the track, and then the mounting seat is welded on the gantry crane at the position of the four-point anchoring, and then the lifting device and the anchoring oil cylinder are fixed on the mounting seat. Then, taking the lifting device and the anchoring oil cylinder connected with the gantry crane as a reference standard, the center point is formed by the lifting device and the anchoring device extending to the contact point with the deck, and then the center of the third through hole of the anchoring support is determined according to the second center point. Then the subsequent pin shaft can pass through the third through hole and be locked on the anchoring support, and the welding point is formed on the support plate at the bottom of the anchoring support to fix the anchoring support on the deck. The anchoring support is positioned on the deck, so that the anchoring support welded on the deck is just connected with the lifting device and the anchoring oil cylinder. Therefore, when the equipment at the bottom of the gantry crane needs to be detected or repaired, the gantry crane only needs to slide to the preset point and stop, and then the anchoring oil cylinder and the anchoring support can be precisely anchored. After anchoring, the lifting device is driven to extend, and the anchoring oil cylinder is synchronously extended to limit the extension of the lifting oil cylinder, so that the gantry crane is lifted up, thereby achieving inspection or repair.

[0008] Further, the mounting seat is provided with a first partition plate, a second partition plate perpendicular to the first partition plate, and a third partition plate, the second partition plate and the third partition plate are arranged in parallel, and the first partition plate, the second partition plate and the third partition plate form a containing cavity one, and the first partition plate and the second partition plate form a containing cavity two.

[0013] With the above arrangement, when the piston rod extends downward along the vertical direction, the second piston rod can sequentially pass through the first through hole arranged on the fixing plate, the third through hole arranged on the anchoring support and then penetrate to the bottom of the anchoring support. By arranging the fixing plate between the anchoring oil cylinder and the anchoring support, the distance from the anchoring support to the gantry crane can be reduced. After the second piston rod is locked at the bottom of the anchoring support by the locking assembly, the length of the second piston rod is greater than the distance from the anchoring support to the gantry crane, that is, the moment of the force of the gantry crane on the connection between the second piston rod and the locking assembly is reduced. In addition, the diameter of the second piston rod is greater than that of the first piston rod, which can effectively reduce the bending moment of the gantry crane on the connection between the second piston rod and the locking assembly, thereby stably anchoring the gantry crane and further improving the bending moment resistance.

[0014] Further, one end of the first piston rod and the second piston rod is fixedly connected, the other end of the second piston rod is provided with a second through hole, and the length of the second piston rod is greater than the distance from the upper end surface of the anchoring support to the fixing plate fixed on the gantry crane.

[0015] With the above arrangement, after the second piston rod is connected with the locking assembly by penetrating to the bottom of the anchoring support, the second piston rod is located between the anchoring support and the fixing plate, thereby making the second piston rod with a larger diameter have greater bending moment resistance.

[0016] Further, the bottom of the anchoring support is provided with two or more support plates, two fixing parts are arranged between the support plates, coaxially arranged fifth through holes are arranged on the fixing parts, and the third through hole is located between the fixing parts.

[0017] With the above arrangement, the locking assembly can be connected with the second piston rod after penetrating through the fifth through hole, thereby locking the second piston rod.

[0018] Further, the locking assembly includes a locking pin and a locking plate, one end of the locking pin is provided with a limiting protrusion, a counterbore is arranged on the limiting protrusion, two or more sixth through holes and seventh through holes are arranged on the locking plate, the seventh through holes are arranged on both sides of the sixth through holes, the end of the locking plate is recessed inward along the axial direction to form a receiving groove matched with the limiting protrusion, and the sixth through hole is in communication with the receiving groove.

[0019] The above arrangement can cover the limiting protrusion of the locking pin shaft on the limiting protrusion of the locking pin shaft after the locking pin shaft passes through the second through hole of the second piston rod, so that the limiting protrusion is accommodated in the accommodation groove, and then the limiting protrusion and the locking plate are connected to form an integral whole through the locking member passing through the sixth through hole, and at the same time, the locking plate is fixed on the fixed part through the locking member passing through the seventh through hole, thereby limiting the movement of the locking pin shaft in the axial direction, thereby achieving locking of the second piston rod.

[0020] Further, the diameter of the locking pin shaft matches the diameter of the second through hole and is smaller than the diameter of the fifth through hole.

[0021] The above arrangement can drive the second piston rod to move upward along the vertical direction by the anchoring oil cylinder, and then drive the locking pin shaft to move upward until the locking pin shaft abuts against the inner side wall of the fifth through hole and stops moving, at this time, the locking plate is fixed on the fixed part through the seventh through hole of the locking member, to realize the stable connection between the locking assembly, the anchoring support and the second piston rod.

[0022] Further, in step S1, after the anchoring oil cylinder is fixed on the mounting seat, the fixed plate is welded and fixed on the lower end of the first partition plate, the second partition plate and the partition strip fixed on the mounting seat, and the first through hole on the fixed plate is aligned with the second piston rod on the anchoring oil cylinder.

[0023] The above arrangement facilitates the anchoring oil cylinder to drive the second piston rod to pass through the first through hole of the fixed plate.

[0024] Further, the step S4 further comprises: After the anchoring oil cylinder drives the second piston rod to extend downward along the vertical direction and penetrates through the third through hole to the bottom of the anchoring support, the locking pin shaft passes through the second through hole of the second piston rod, and then the anchoring oil cylinder drives the second piston rod to move upward along the vertical direction, thereby driving the locking pin shaft to move upward until the locking pin shaft abuts against the inner side wall of the fifth through hole and stops moving, The locking plate is covered on the limiting protrusion of the locking pin shaft, so that the limiting protrusion is accommodated in the accommodation groove, and the limiting protrusion and the locking plate are connected to form an integral whole through the locking member passing through the sixth through hole, and at the same time, the locking plate is fixed on the fixed part through the locking member passing through the seventh through hole.

[0025] The above arrangement ensures the stable connection between the locking assembly, the anchoring support and the second piston rod, and avoids loosening between the locking pin shaft and the fixed part in the subsequent process of lifting the gantry crane by the jacking oil cylinder.
