Description

Technical Field

[0001] The present invention relates to the technical field of lifting equipment, and in particular to an adjustable quay crane rail-bearing beam joint. Background Art

[0002] A quay crane, also known as a shore container crane, is a device that uses a trolley to move back and forth on tracks, loading and unloading containers from container ships using a sling. Some quay cranes have two beams, front and rear, with front and rear rails installed on the front and rear beams, respectively. The front and rear beam tracks are located on the front and rear rails, respectively. In current quay cranes, the front and rear rails are supported by the rear and front beams' joints. However, since the two are separated, when the trolley wheels travel from the rear beam track to the front beam track and pass through the transition joint between the front and rear beams' rails, the rear beam track, independently bearing the load, will deflect due to the trolley's own weight and the load. Since the front beam track is unloaded at this time, a height difference between the rear and front beams will form. Similarly, when the trolley wheels travel from the front beam track to the rear beam track, a height difference will also form. Due to the height difference of the tracks, the trolley wheels will produce abnormal noises and vibrations when passing through the front and rear beam track transition joints, which is not conducive to the trolley operator's container loading and unloading operations on the quay crane.

[0055] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of the present invention.

[0056] To facilitate understanding of the technical solution of the present invention, the technical problem to be solved by the present invention is first described.

[0057] like Figure 1 As shown, the existing quay crane beam includes a first rear beam 101 and a first front beam 201 that are abutted against each other, and the side surfaces of the first rear beam 101 and the side surfaces of the first front beam 201 are respectively provided with a first rear beam rail beam 102 and a first front beam rail beam 202, the first rear beam rail 103 and the first front beam rail 203 are abutted against each other and are respectively provided on the first rear beam rail beam 102 and the first front beam rail beam 202, and the joints of the first rear beam rail beam 102 and the first front beam rail beam 202 are respectively provided with mutual The abutting first rear beam rail support beam joint 104 and the first front beam rail support beam joint 204 are arranged separately from each other. When the trolley wheel runs from the first rear beam rail 103 to the first front beam rail 203 and passes through the transition joint, due to the influence of the trolley's own weight and the hoisting load, the first rear beam rail 103 independently bears the load and will produce downward deformation. Since the first front beam rail 203 is not bearing any load at this time, a track height difference will be formed between the first rear beam rail 103 and the first front beam rail 203. Similarly, when the trolley wheel runs from the first front beam rail 203 to the first rear beam rail 103, a track height difference will also be formed. Due to the existence of the track height difference, abnormal noise and vibration will be generated when the trolley wheel passes through the transition joint between the front and rear beam rails. On the one hand, it poses a safety hazard. On the other hand, it is not conducive to the trolley operator to carry out container loading and unloading operations on the quay crane.

[0058] In order to solve the above technical problems, the present invention provides an adjustable quay crane rail bearing beam joint.

[0059] First, an adjustable quay crane rail support beam joint according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0060] like Figure 2 and Figure 3As shown, the adjustable quay crane rail beam joint of the embodiment of the present invention may include: a rear beam rail beam joint 300, a front beam rail beam joint 400, and an adjustment support block 500. The rear beam rail beam joint 300 includes a rear rail beam support 310 and a rear rail beam 320. The rear rail beam support 310 is arranged along the first direction and is connected to the end of the rear beam 600 facing the front beam 700. The length direction of the rear rail beam 320 is consistent with the second direction. The rear rail beam 320 is connected to the side of the rear rail beam support 310 away from the rear beam 600. The rear rail beam main web 321 of the rear rail beam 320 faces one side of the front beam 700. The front end of the front beam rail beam joint 400 includes a front rail beam boss 410 and a front rail beam 420. The front rail beam boss 410 is arranged along the first direction and is connected to the end of the front beam 700 facing the rear beam 600. The length direction of the front rail beam 420 is consistent with the second direction and is connected to the side of the front rail beam boss 410 away from the front beam 700. The front rail beam main web 421 of the front rail beam 420 faces the rear beam 600. 00 is provided with a second arc-shaped opening 423 at one end, the top surface of the front rail beam 420 is flush with the top surface of the rear rail beam 320, and the front rail beam boss 410 is in contact with the rear rail beam support 310; the adjustment support block 500 is provided at the end of the second arc-shaped opening 423 of the main web plate 421 of the front rail beam facing the rear beam 600, and the adjustment support block 500 is used to abut with the first arc-shaped opening 322 and the height of the adjustment support block 500 is adjustable; wherein, the second direction is consistent with the length direction of the front beam 700 and the rear beam 600, the first direction is perpendicular to the second direction, and the first direction and the second direction are both perpendicular to the vertical direction, the adjustment support block 500 is located below the first arc-shaped opening 322 and the front rail beam boss 410 is located above the rear rail beam support 310, or the adjustment support block 500 is located above the first arc-shaped opening 322 and the front rail beam boss 410 is located below the rear rail beam support 310.

[0061] In one embodiment of the present invention, the adjustment support block 500 is arranged at one end of the second arc-shaped starter 423 facing the rear beam 600 and is also located below the first arc-shaped opening 322. At this time, the front rail beam boss 410 is located above the rear rail beam support 310. The adjustment support block 500 can abut against the first arc-shaped opening 322 and support the rear rail beam 320 upward. The rear rail beam support 310 can abut against the front rail beam boss 410 and support the front rail beam boss 410 upward. Since the adjustment support block 500 is set at one end of the front rail beam main web 421 of the front rail beam 420 facing the rear beam 600, when the trolley runs from the rear beam rail 610 set on the rear rail beam 320 to the front beam rail 710 set on the front rail beam, the adjustment support block 500 and the first arc-shaped opening 322 play a major role. The trolley's own weight and the hoisted load will be transmitted to the adjustment support block 500 via the rear support rail beam 320 in the vertical direction, and then transmitted to the front support rail beam 420 in the vertical direction. Similarly, when the trolley runs from the front beam rail 710 set on the front support rail beam to the rear beam rail 610 set on the rear support rail beam 320, the rear support rail beam support 310 and the front support rail beam boss 410 play a major role. The trolley's own weight and the hoisted load will be transmitted to the rear support rail beam support 310 via the front support rail beam boss 410 in the vertical direction. Therefore, when the wheels of the trolley pass through the joint of the rear beam support rail beam joint 300 and the front beam support rail beam joint 400, the rear beam support rail beam joint 300 and the front beam support rail beam joint 400 will be subjected to loads in the vertical direction at the same time. As a result, the rigidity of the joints between the front and rear beams is improved, avoiding the height difference between the rear beam rail 610 and the front beam rail 710, which would cause abnormal noise, vibration, etc. when the trolley passes through, eliminating safety hazards, and improving the efficiency of the trolley operator in container loading and unloading operations on the quay crane. In addition, the height of the adjustment support block 500 can be adjusted so that the adjustment support block 500 can fully abut against the first arc-shaped opening 322 to ensure stable support.
