Description

Technical Field

[0001] The invention relates to a quay crane sliding tool, and more specifically to an integral sliding tool and method for a lower cross beam of a quay crane and a trolley traveling assembly. Background Art

[0002] Combination Figure 1 As shown, during the current modification of the quay crane track gauge, since the trolley travel mechanism 200 and the lower cross beam 201 are connected via the connecting support 202 and the pin shaft 203, as shown in FIG. Figure 1 (a) The welded connection support 202 and the trolley travel mechanism 200 are connected by a pin 203, as shown in FIG. Figure 1 (b) The flange-type connection support 202 and the trolley travel mechanism 200 are connected by a pin 203. If the connection is disassembled and then displaced, the following difficulties will be encountered:

[0003] 1) After the quay crane has been in use for a long time, it is difficult to remove the pins and high-strength bolts, which affects the construction period;

[0004] 2) After disassembly, the verticality deviation of the trolley's traveling mechanism will be caused, making adjustment difficult.

[0005] At the same time, the quay crane equipment at user terminals often needs to expand or reduce the track gauge. The main reason for the expansion and reduction of the track gauge of the quay crane is that the track layout of the terminal is different after the quay crane is moved to the new terminal, which causes the quay crane to reduce or expand the track gauge according to the actual situation of the new terminal.

[0006] There are two main ways to change the track gauge that are commonly used in the market: one is to use a truck crane to lift the trolley travel mechanism and the lower beam as a whole after the column is disconnected; the other is to disassemble the trolley and the lower beam into parts and slowly move them with a forklift or truck crane. The main disadvantages of these two methods are as follows:

[0007] 1) The use of mobile equipment is expensive and has a long working cycle;

[0008] 2) After reaching the new track gauge, positioning and adjusting the dimensions are difficult and take a long time. Summary of the invention

[0009] In view of the above-mentioned defects existing in the prior art, the purpose of the present invention is to provide an integral sliding tooling and method for the lower crossbeam and trolley walking assembly of the quay crane, so as to solve the problem of difficulty in shifting the existing trolley and the lower crossbeam and ensure the smooth shifting of the trolley and the lower crossbeam.

[0050] In order to better understand the above technical solution of the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0051] Combination Figures 2 to 4 As shown, the present invention provides an integral sliding tooling for a lower cross beam of a quay crane and a trolley traveling assembly, comprising a cushion beam 1, an anti-tilt leg 2, a cantilever beam 3, a lifting device 4, a sliding device 5 and an MGE slider 6.

[0052] The cushion beam 1 is arranged directly below the lower cross beam 100. The high-strength rigid beam structure of the cushion beam 1 disperses the pressure of the sliding components (the lower cross beam 100 and the connected trolley travel mechanism) and reduces the load requirement on the wharf. The cushion beam 1 adopts a box beam structure, and the upper surface of the cushion beam 1 is covered with a stainless steel sheet slide 7.

[0053] The cantilever beam 3 is arranged above the cushion beam 1 and is connected to the lower cross beam 100 through a flange, so as to ensure the overall fixation of the integral sliding tooling of the present invention and prevent the trolley walking mechanism from deflecting.

[0054] The upper end of the anti-tilt leg 2 is connected to the cushion beam 3, and the lower end is connected to the MGE slider 6. The MGE slider 6 contacts and cooperates with the slide groove 7 on the upper surface of the cushion beam 1. The main function of the anti-tilt leg 2 is to prevent the trolley walking mechanism from tipping forward and backward during the sliding process.

[0055] The MGE slider 6 reduces the friction during the sliding process and facilitates the sliding adjustment.

[0056] The lifting device 4 is arranged on the upper surface of the cushion beam 1 to lift the cantilever beam 3. The lifting device 4 includes a hydraulic jack 12 arranged on the upper surface of the cushion beam 1, and a pad 13 arranged on the top of the hydraulic jack 12 and in contact with the cantilever beam. The lifting force of the hydraulic jack 12 ensures that the sliding component is lifted as a whole, which is convenient for installing the anti-tilt leg 2 and the MGE slider 6.

[0057] The sliding device 5 is arranged on the upper surface of the cushion beam 1 and connected to the anti-tilt leg 2. The anti-tilt leg 2 is pushed by the slow force of the screw jack 14, and the sliding component is driven to slide slowly. The sliding device 5 includes a screw jack 14 connected to the anti-tilt leg 2, and a cushion block 15 arranged between the screw jack 14 and the fixed block 8.

[0058] The upper surface of the cushion beam 1 is also provided with a fixing block 8 connected to the sliding device 5 to ensure the lifting thrust of the sliding device 5 during the sliding process.

[0059] Combination Figure 5 As shown, both ends of the cushion beam 1 are provided with lifting ears 9 for easy lifting.

[0060] Combination Figure 6 As shown, the cantilever beam 3 adopts a box beam structure, and both ends thereof are provided with lifting ears 10 for easy lifting. The upper and lower surfaces of the cantilever beam 3 are provided with flange plates 11 for connecting the lower cross beam 100 and the anti-tilt leg 2.

[0061] Combination Figure 7 As shown, the anti-tilt leg 2 includes a vertical plate 16, an upper flange plate 17 and a lower flange plate 18 connected to the upper and lower ends of the vertical plate 16, and a reinforcing rib plate 19 arranged on the side of the vertical plate 16. The upper flange plate 17 is connected to the flange plate 11 on the lower surface of the cantilever beam 3 by bolts.

[0062] Combination Figure 8 and Fig. 9 As shown, the fixing block 8 includes a bottom plate 20 disposed on the upper surface of the cushion beam 1, and three triangular rib plates 21 evenly distributed on the upper surface of the bottom plate 20. Bolt holes 22 are provided on the bottom plate 20, and the bottom plate 20 is fixedly connected to the cushion beam 1 by bolts.

[0063] The present invention also provides an integral sliding method for the lower cross beam of the quay crane and the traveling assembly of a large vehicle, and the integral sliding tooling for the lower cross beam of the quay crane and the traveling assembly of the large vehicle of the present invention is used to perform the following steps:

[0064] S1. Before construction, the lower cross beam 100 and the connected trolley travel mechanism are protected from overturning (pull the steel wire rope or add a rigid bracket for support); then the wheel clamp device under the lower cross beam 100 is removed, the cushion beam 1 is arranged, and leveling is performed according to the condition of the wharf;

[0065] S2, install the cantilever beam 3 on the lower cross beam 100, lift the cantilever beam 3 by the lifting device 4 and lift the lower cross beam 100 at the same time, the lifting device 4 maintains pressure, install the anti-tilt leg 2 on the cantilever beam 3, and install the MGE slider 6 on the bottom of the anti-tilt leg 2;

[0066] S3, the lifting device 4 slowly releases pressure until the MGE slider 6 contacts the upper surface of the cushion beam 1 and is fully compacted (at the same time, check whether the wheel edge is higher than the upper surface of the pre-buried rail of the wharf);

[0067] S4, using the sliding device 5 to push the anti-tilt leg 2, so that the lower cross beam 100 and the trolley travel mechanism slide along the slide groove 7 of the cushion beam 1 for a stroke;

[0068] S5, after the lower cross beam 100 and its trolley traveling mechanism slide one stroke, the sliding device 5 is pressed back, and a cushion block 15 is placed between the sliding device 5 and the fixed block 8, and the sliding device 5 is used again to push the anti-tilt leg 2, so that the lower cross beam 100 and its trolley traveling mechanism slide one stroke along the slide groove of the cushion beam;

[0069] S6. Repeat step S5 until the lower cross beam 100 and its trolley travel mechanism slide to the specified position.

[0070] In summary, the overall sliding fixture and method of the lower crossbeam and trolley traveling assembly of the quay crane of the present invention is aimed at the situation that the quay crane equipment of the existing dock often needs to expand or reduce the track gauge, ensuring the safety of the construction process, while also ensuring the smooth displacement of the lower crossbeam and the trolley traveling mechanism.
