Description

Technical Field

[0001] The 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 a track and load and unload containers on a container ship with a sling. The beams of some quay cranes are divided into two beams, front and rear, and the front beam and rear beam are respectively provided with a front rail beam and a rear rail beam, and the front and rear beam tracks are respectively provided on the front rail beam and the rear rail beam. In the current quay cranes, the front and rear rail beams are supported by the rear beam rail beam joint and the front beam rail beam joint, but since the two are separated from each other, when the wheels of the trolley run from the rear beam track to the front beam track and pass through the transition joint of the front and rear beam rail beams, due to the influence of the trolley's own weight and the hoisting load, the rear beam track will be independently loaded and deformed downward, and since the front beam track is not loaded at this time, the rear beam track and the front beam track will form a track height difference. Similarly, when the wheels of the trolley run from the front beam track to the rear beam track, a track height difference will also be formed. 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 conversion joints, which is not conducive to the trolley operators performing container loading and unloading operations on the quay crane.

[0055] 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.

[0056] To facilitate the 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-bearing beam 102 and a first front beam rail-bearing 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-bearing beam 102 and the first front beam rail-bearing beam 202, and the joints of the first rear beam rail-bearing beam 102 and the first front beam rail-bearing beam 202 are respectively provided with mutual The first rear beam rail-bearing beam joint 104 and the first front beam rail-bearing beam joint 204 are abutted for support. Since the two are separated from each other, when the trolley wheel runs from the first rear beam track 103 to the first front beam track 203 and passes through the conversion joint, due to the influence of the trolley's own weight and the hoisting load, the first rear beam track 103 independently bears the load and will produce downward deflection. Since the first front beam track 203 is not loaded at this time, the first rear beam track 103 and the first front beam track 203 will form a track height difference. Similarly, when the trolley wheel runs from the first front beam track 203 to the first rear beam track 103, a track height difference will also be formed. Due to the existence of the track height difference, abnormal noise, vibration and other phenomena will be generated when the trolley wheel passes through the front and rear beam track conversion joints. On the one hand, there is a safety hazard, and 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] Firstly, an adjustable quay crane rail bearing beam joint according to an embodiment of the present invention is described in detail below with reference to the accompanying drawings.

The rear beam main web 321 of the rear beam 320 faces one end of the front beam 700. 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 connected to one 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 connected to the side of the front rail beam boss 410 away from the front beam 700, and the front rail beam main web 421 of the front rail beam 420 faces the rear beam 600. A second arc-shaped opening 423 is provided at one end of 00, 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 421 of the front rail beam facing the rear beam 600, 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.

As a result, the rigidity of the joint between the front and rear beams is improved, and the height difference between the rear beam rail 610 and the front beam rail 710, which causes abnormal noise, vibration and the like when the trolley passes, is avoided. This eliminates safety hazards and improves the efficiency of the trolley operator in container loading and unloading operations on the quay crane.
