[0002] The trolley travel mechanism of the shore container crane (hereinafter referred to as the quay crane) is the only left and right moving part in the quay crane structure. Generally, it is composed of four sets of trolley mechanisms.

[0003] After arriving at the user's wharf at the shore, the trolley gauge needs to be adjusted. There are two main adjustment methods in the existing technology: ① Loosen the upper adjustment bolt of the trolley walking support, and the quay crane reciprocates along the direction of the track, and use the rigidity of the pre-buried track at the wharf to adjust the gauge; ② Loosen the high-strength bolts connecting the large balance beam and the lower crossbeam support, and the quay crane runs back and forth along the direction of the wharf track, and adjust the trolley straightness and gauge to the correct position by using the gap between the bolts and the bolt holes.

DETAILED DESCRIPTION

[0050] In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0051] Unless otherwise defined, the technical terms or scientific terms used in the present invention shall have the usual meanings understood by persons with ordinary skills in the field to which the present invention belongs. The words "first", "second" and similar words used in the present invention do not indicate any order, quantity or importance, but are only used to distinguish different components. Similarly, words such as "one" or "one" do not indicate quantity restrictions, but indicate the existence of at least one. Words such as "connect" or "connected" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship also changes accordingly.

[0052] The following first describes in detail the adjusting device for adjusting the track gauge of a trolley according to an embodiment of the present invention in conjunction with the accompanying drawings.

[0053] The adjusting device 001 according to the embodiment of the present invention is used to adjust the track gauge of a trolley.

[0054] Figure 1 The structure of the trolley travel mechanism is shown. The trolley travel mechanism is composed of four groups of trolleys. Each group of trolleys 002 has a trolley crossbeam 003. Figure 1 and 2 As shown, movable wheels are provided at both ends below the trolley cross beam 003. The adjusting device 001 of the embodiment of the present invention is used to adjust the distance between the two trolley cross beams 003, that is, the track gauge.

[0055] Specifically, if Figure 2 and Figure 3 As shown, the adjustment device 001 of the embodiment of the present invention is used to abut under the trolley cross beam, and then change the distance between the two opposite trolley cross beams 003 through lateral adjustment.

[0056] Next, combine Figure 3-Figure 8 , firstly, the adjustment device 001 according to an embodiment of the present invention is described.

[0057] like Figures 3 to 8As shown, the adjusting device 001 according to the embodiment of the present invention includes a chassis 100 , a body 200 , a lifting mechanism 300 , a lifting beam 400 and a lateral adjustment mechanism 500 .

[0058] Specifically, Figure 4 As shown, the body 200 is movably arranged on the chassis 100, the lifting mechanism 300 is arranged on the body 200, the lifting mechanism 300 can be raised / lowered, and the lifting beam 400 is movably arranged on the body 200 and is located above the lifting mechanism 300 so as to be lifted / restored by the lifting mechanism 300. More specifically, when the lifting mechanism 300 is lifted / lowered, the lifting beam 400 is driven to move by driving the body 200 to lift / lower. Among them, the lifting beam 400 is used to abut against the trolley cross beam 003 of the trolley 002, as shown in FIG. Figures 2 to 3 As shown, the lifting beam 400 of the adjustment mechanism 001 abuts against the bottom of the trolley beam 003, that is, the lifting mechanism 300 rises / falls, which can sequentially drive the main body 200 and the lifting beam 400 to drive the trolley beam 003 of the trolley 002 to move, so that the trolley beam 003 of the trolley 002 is lifted / restored.

[0059] The lateral adjustment mechanism 500 is arranged on one side of the chassis 100 (corresponding to Figure 5 At the left end shown in the figure, in specific use, the adjustment direction of the transverse adjustment mechanism 500 is arranged vertically relative to the trolley cross beam 003) and is connected to the body 200. The transverse adjustment mechanism 500 is used to drive the body 200 to move laterally on the chassis 100 along the extension direction of the lifting beam 400 (also perpendicular to the direction of the trolley cross beam 003) to drive the trolley cross beam 003 to move laterally. In other words, the transverse adjustment mechanism 500 can sequentially drive the body 200 and the lifting beam 400 to drive the trolley cross beam 003 of the trolley 002 to move laterally along the extension direction of the lifting beam 400, thereby achieving the function of adjusting the trolley track gauge.

[0060] The adjustment device 001 of the embodiment of the present invention first uses the lifting mechanism 300 to drive the main body 200 to move to drive the trolley crossbeam 003 to lift up, and then uses the lateral adjustment mechanism 500 to perform lateral adjustment on the lifted trolley crossbeam 003, thereby achieving high-precision adjustment of the trolley track gauge.

[0061] According to some embodiments of the present invention, Figure 5As shown, the chassis 100 of the adjustment device 001 of the embodiment of the present invention is provided with a first limit portion 110 in the lateral direction, and the first limit portion 110 is used to guide the body 200 to move in the lateral direction. In other words, the first limit portion 110 limits the body 200 to move only in the lateral direction, and will not deviate in other directions during the movement. Therefore, when the lateral adjustment mechanism 500 drives the body 200 and the lifting beam 400 to drive the trolley cross beam 003 to move lateral, the first limit portion 110 can prevent the body 200 from running off the track due to improper installation position of the lateral adjustment mechanism 500 or the body 200, thereby further improving the adjustment accuracy of the trolley track gauge. For example, the first limit portion 110 may include two rows of baffles or blocks, and the two rows of baffles or blocks are respectively arranged on both sides of the body 200 (corresponding to Figure 5 The side closer to the observer and the side farther away from the observer are shown).

[0062] In addition, at the end opposite to the lateral adjustment mechanism 500 (corresponding to Figure 2 The right end of the body 200 is also provided with a second limiter 120 to limit the maximum lateral displacement position of the body 200. By setting the second limiter 120, it is possible to prevent the lateral adjustment distance from being too large due to a malfunction of the lateral adjustment mechanism 500, thereby possibly causing an accident, thereby improving the reliability of the adjustment device.

[0063] In addition, if Figure 5 As shown, the second limiting portion 120 may also be provided with one or more reinforcing ribs to improve the installation strength and reliability of the second limiting portion 120 .

[0064] It should be noted that the structure of the first limiting portion 110 is not limited to the baffles or blocks arranged on both sides of the body 200, and the structure of the second limiting portion 120 is not limited to the baffles and reinforcing ribs arranged on the opposite side of the lateral adjustment mechanism 500. The first limiting portion 110 can be other guiding structures for guiding the movement of the assembly, for example, it can also include one or more slide rails, and the slide rails are connected to the bottom of the body 200, which can be used to guide the body 200 to move in the lateral direction. Accordingly, the second limiting portion 120 can be, for example, arranged at one end of the slide rail, that is, a limiting block is arranged on one end of the slide rail, or a first protrusion is extended on the side wall of the slide rail. The first limiting portion 110 can also include, for example, one or more slide grooves, which are arranged on the chassis 100, and a protrusion that cooperates with the slide groove is arranged at the bottom of the body 200 to form a concave-convex structure to guide the body 200 to move in the lateral direction. Accordingly, the second limiting portion 120 can also be, for example, arranged at one end of the protrusion, and the second limiting portion 120 can be a second protrusion whose width is greater than the width of the slide groove.

[0065] Furthermore, if Figure 5As shown, the chassis 100 may also be provided with a scale 130 adjacent to the transverse adjustment mechanism 500. Specifically, the scale 130 may be provided on one side of the chassis 100 for easy observation by the operator. The zero scale line of the scale 130 may also be provided, for example, at a position flush with the contact surface of the body 200 and the output end of the transverse adjustment mechanism 500 when the transverse adjustment mechanism 500 is in the initial state, so that the operator can observe the transverse driving distance of the transverse adjustment mechanism 500, that is, the transverse adjustment distance of the trolley, further improving the accuracy of the trolley gauge adjustment.

[0066] Furthermore, if Figure 4 As shown, the lateral adjustment mechanism 500 of the embodiment of the present invention may include a mounting seat 510 and an adjustment jack 520. The mounting seat 510 is fixed on the chassis 100, and the adjustment jack 520 is mounted on the mounting seat 510 and the adjustment jack 520 abuts against one end of the body 200 (corresponding to Figure 1 The mounting seat 510 improves the installation reliability of the adjusting jack 520. The adjusting jack 520 drives the body 200 to move laterally, so that the body 200 drives the cross beam of the large vehicle to move laterally. Among them, the surface of the mounting seat 510 away from the adjusting jack 520 can be provided with one or more reinforcing ribs to improve its stability and reliability. Furthermore, one or more blocks can be provided on the outer side of the output shaft of the adjusting jack 520 to further firmly fix the adjusting jack 520 on the chassis 100.

[0067] Furthermore, if Figure 6-Figure 8 As shown, the body 200 of the embodiment of the present invention may include, for example, a lifting support 210 and a plurality of lifting pads 220. Specifically, the lifting support 210 may further include a support body 211 and two support legs 212 spaced apart and arranged on the support body 211. Figure 6 As shown, the lifting mechanism 300 is arranged between two supporting legs 212, and the lifting pad 220 is used to be arranged on the supporting legs 212 to abut the lifting beam 400. That is to say, the lifting support 210 is arranged on the chassis 100, and a plurality of lifting pads 220 are stacked and arranged on the lifting support 210 as needed, and the top of the lifting support 210 abuts the lifting beam 400. More specifically, the support body 211 of the lifting support 210 is arranged on the chassis 100, and the adjustment jack 520 of the lateral adjustment mechanism 500 abuts one end of the support body 211, which is used to drive the body 200 to move laterally. Two supporting legs 212 are arranged on the support body 211, and the supporting legs 212 are used to connect the lifting pads 220. The lifting beam 400 is arranged above the lifting pads 220, and the lifting beam 400 can abut the trolley cross beam 003 after being lifted. In addition, as Figure 1As shown, a lifting pad 220 may also be provided on the lifting mechanism 300 to reduce the lifting displacement of the lifting mechanism 300 , which has the advantages of improving adjustment efficiency and saving energy and reducing emissions.

[0068] Further, as a preferred embodiment, Figure 6 As shown, the support leg 212 is formed in a quadrangular prism shape, and the four corners of the top of the quadrangular prism are respectively provided with first pad shear blocks 212a to abut against the four corners of the jacking pad 220. The quadrangular prism-shaped support leg 212 is convenient for the operator to stack the jacking pad 220 thereon, and the first pad shear block 212a has a limiting effect on the jacking pad 220, avoiding the risk of the jacking pad 220 falling off during the process of moving the trolley cross beam 003, thereby improving the stability and reliability of the adjustment device.

[0069] Further, as another preferred embodiment, Figure 7 As shown, the four corners of the jacking pad 220 are respectively provided with a bending baffle 221, which is bent into an L shape, and the inner wall of the L shape is respectively connected to the two outer walls of the adjacent bending baffle 221, and the L shape extends upward to form a limit unit 221a, which is bent outward of the jacking pad 220 to limit the movement of the upper and lower adjacent jacking pads 220. The limit unit 221a of the bending baffle 221 improves the reliability of the installation of the two upper and lower adjacent jacking pads 220, and at the same time, avoids the deviation between the multiple stacked jacking pads 220, which may cause the center of gravity of the jacking beam 400 and the trolley cross beam to shift, thereby further improving the reliability of the adjustment device. Furthermore, a handle 222 is also provided on the side wall of the jacking pad 220, and the handle 222 and the side wall of the jacking pad 220 form a gripping space to lift the jacking pad 220. The handle 222 can facilitate the operator to lift the jacking pad 220, thereby improving the convenience of operation.

[0070] Furthermore, if Figure 8 As shown, the lower surface of the lifting beam 400 is provided with a plurality of second pad shear blocks 410, which are located on both sides of the lifting pad 220 in the lateral direction. The second pad shear blocks 410 are used to limit the lifting pad 220 abutting against the lifting beam 400, so as to avoid the lifting pad 220 at the abutment position deviating from other stacked lifting pads 220, further improving the reliability of the adjustment device. The upper surface of the lifting beam 400 is provided with a plurality of balance beam shear blocks 420, which are used to abut against both sides of the trolley cross beam 003, and the balance beam shear blocks 420 are used to limit the trolley cross beam 003, so as to avoid the center of gravity of the trolley cross beam 003 deviating from the center of gravity of the lifting beam 400, further improving the reliability of the adjustment device.

[0071] The specific operation process of adjusting the track gauge of a large vehicle using the adjusting device 001 of the embodiment of the present invention is as follows:

[0072] First, the adjusting device 001 is set at the position where the track gauge of the large vehicle needs to be adjusted. Figure 1-2 As shown, multiple adjustment devices 001 can be set under the corresponding trolley beam. Compared with one adjustment device 001, the use of multiple adjustment devices 001 avoids repeated disassembly and assembly of the adjustment device 001 during adjustment, and can be repeatedly debugged during the retest process, which is not only conducive to improving the adjustment accuracy, but also can adjust the track gauge of each group of trolleys at the same time, thereby improving work efficiency. The lifting mechanism 300 is used to drive the body 200 to move to drive the trolley beam 003 to lift up; then the lateral adjustment mechanism 500 is used to perform lateral adjustment on the lifted trolley beam 003; after the adjustment is completed, the lifting mechanism 300 is used to drive the body 200 to move to drive the trolley beam 003 to recover, so that the wheels of the trolley 001 fall into the trolley track.

[0073] Specifically, first, the adjustment device 001 is set. It should be noted that, if Figure 8 As shown in (a), before setting the adjustment device, the lifting pad 220 can be pre-stacked on the support foot 212 and the lifting mechanism 300 to facilitate operation.

[0074] Secondly, the lifting mechanism 300 operates, and the lifting mechanism 300 drives the lifting beam 400 to move, such as Figure 8 As shown in (b), the lifting beam 400 is brought into contact with the trolley cross beam 003, and the lifting beam 400 is continuously driven to move until one side of the trolley 002 is lifted up.

[0075] Next, a lifting pad 220 is added to the support leg 212 to connect the body 200 with the lifting beam 400. Figure 8 As shown in (c), after one side of the cart 002 is lifted up, the lifting mechanism 300 can be lowered, and the lifting beam 400 and the cart 002 are supported by the supporting legs 212 on both sides of the lifting beam 400, which plays a role in protecting the lifting mechanism 300 and has the advantages of energy saving and emission reduction.

[0076] Then, if Figure 8 As shown in (d), the lateral adjustment mechanism 500 is used to drive the main body 200, the lifting beam 400 and the trolley cross beam to move laterally along the extension direction of the lifting beam 400.

[0077] Finally, the lifting mechanism 300 is brought into contact with the lifting beam 400, and the lifting pad 220 added to the support leg 212 is removed. Figure 8 As shown in (e), the lifting mechanism 300 drives the lifting beam 400, the trolley beam 003 and the trolley 002 to move downward, and finally the wheels of the trolley 002 fall into the trolley track.

[0078] It is worth noting that Figure 4 As shown, a plurality of wooden boards 600 can also be laid on the bottom of the chassis 100 to prevent the large vehicle 002 and the adjusting device 001 from exerting excessive pressure on the ground and causing damage to the road surface. At the same time, the size of the chassis 100 is determined by the specifications of the large vehicle 002 and the large vehicle cross beam 003. At the same time, the design of the main body 200 and the lifting beam 400 on the chassis 100 also needs to meet the strength and rigidity requirements, and the horsepower of the lifting mechanism 300 and the lateral adjustment mechanism 500 is also determined by the specifications of the large vehicle 002 and the large vehicle cross beam 003.

[0079] In addition, in order to facilitate the sliding of the body 200 on the chassis 100, lubricating oil needs to be applied between the chassis 100 and the body 200, and Figure 5 As shown, side oil baffles 140 are arranged around the chassis 100 to prevent lubricating oil from overflowing from the chassis 100 and causing environmental pollution.

[0080] In addition, the present invention also provides a method for adjusting the gauge of a trolley based on the adjusting device for adjusting the gauge of a trolley. Fig. 9 A flow chart of a method for adjusting the track gauge of a trolley based on the above-mentioned adjustment device according to an embodiment of the present invention is shown, comprising the following steps:

[0081] S1, the quay crane is shut down and the movable parts on the trolley are tied and fixed;

[0082] S2, testing the current track gauge of the vehicle;

[0083] S3, determining the position to be adjusted and the adjustment distance according to the current track gauge; Fig.10 As shown, a deformation diagram of the trolley travel mechanism can be drawn. The trolley travel mechanism is formed into a quadrilateral. The distances L1, L2, L3, and L4 between any two groups of trolleys arranged opposite to each other are measured, where L1 and L4 are the distances between the two ends of the two groups of trolleys, and L2 and L3 are the distances between the middle sections of the two groups of trolleys, respectively. The diagonal distances L5 and L6 between the ends of any two groups of trolleys are measured, and the position to be adjusted and the adjustment distance are calculated and determined based on the measured L1, L2, L3, L4, L5, and L6.

[0084] S4, according to the position to be adjusted in S3, one or more adjustment devices 001 are set under the cart beam 003 corresponding to the position to be adjusted, and the lifting mechanism 300 is driven to control the lifting beam 400 to rise, so that the lifting beam 400 is connected to the cart beam 003, and the driving is continued to make one side of the cart 002 leave the track, such as Figure 4 As shown;

[0085] S5, driving the lateral adjustment mechanism 500 to make the body 200 move laterally on the chassis 100 along the extension direction of the lifting beam 400 to drive the trolley cross beam 003 to move laterally by the adjustment distance in S3;

[0086] S6, driving the lifting mechanism 300 to control the lifting beam 400 to descend, so that one side of the trolley 002 falls back to the track.

[0087] In addition, after the lateral movement adjustment distance, the current track gauge of the trolley is re-measured. If the track gauge of the trolley is unqualified, the above S3 to S6 are repeated until it is qualified; if the track gauge of the trolley is qualified, the function of the whole machine is restored.

[0088] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
