Description

Technical Field

[0001] The invention relates to the technical field of lifting and handling equipment, and in particular to a transverse telescopic mechanism of a high seas-railway combined transport loading and unloading device. Background Art

[0002] In industrial production, it is usually necessary to transport large workpieces such as pressure vessels within the factory. In the prior art, the workpieces are mainly loaded and unloaded and moved within the factory through dedicated, mobile handling devices. Since large workpieces have large width and height dimensions, the matching handling devices also require corresponding width and height dimensions, which makes it difficult for them to pass through some narrow intersections, warehouse entrances, cargo ship passages, etc. In actual use, large handling devices need to pass through narrow openings when they are unloaded, such as entering a warehouse unloaded. This requires the handling device to have the function of adjusting the horizontal width and height to flexibly adapt to various factory environments and meet usage requirements. Summary of the invention

[0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a transverse telescopic mechanism for a high seas-railway intermodal loading and unloading device, so that the high seas-railway intermodal loading and unloading device has the function of adjusting the transverse width, thereby improving the passing performance of the handling device and better meeting the use requirements.

[0004] In order to achieve the above-mentioned purpose, the present invention provides a transverse telescopic mechanism of a high seas-rail intermodal loading and unloading device, comprising a telescopic beam and a beam guide sleeve which are sleeved together, wherein the outer end of the telescopic beam is connected to one of the frame structures of the high seas-rail intermodal loading and unloading device, and the outer end of the beam guide sleeve is connected to the other frame structure, and the telescopic beam can slide relative to the beam guide sleeve, and the transverse telescopic mechanism also includes a transverse telescopic driving part, wherein the two ends of the transverse telescopic driving part are respectively connected to the two frame structures, and a running part is arranged at the bottom of the frame structure.

[0005] Furthermore, a reinforcement plate is provided on the outer side wall of the inner end of the crossbeam guide sleeve.

[0006] Furthermore, a limit plate is provided on the outer side wall of the telescopic beam.

[0007] Furthermore, the frame structure is mainly composed of a lower beam, an upper beam and a vertical telescopic portion connecting the lower beam and the upper beam, and two groups of lateral telescopic mechanisms are provided, respectively located at the two ends of the upper beam.

[0008] Furthermore, a connecting beam is fixedly arranged between the two crossbeam guide sleeves, and the middle portion of the connecting beam is connected to the upper beam on the same side of the crossbeam guide sleeves through a connecting sub-beam.

[0009] Furthermore, the transverse telescopic driving part is a transverse telescopic oil cylinder, the bottom end of the transverse telescopic oil cylinder is hinged to one of the upper beams, and the end of the piston rod is hinged to the other upper beam.

[0010] Furthermore, the running part is arranged at the bottom of the lower beam, the vertical telescopic part enables the upper beam to be raised and lowered relative to the lower beam, and a lifting lug is also arranged on the upper beam.

[0011] The above scheme of the present invention has the following beneficial effects:

[0012] The transverse telescopic mechanism applied to the high seas-railway intermodal loading and unloading device provided by the present invention enables the distance between the two main frame structures of the high seas-railway intermodal loading and unloading device, that is, the width of the device, to be flexibly adjusted. When passing through a narrow opening, the transverse telescopic mechanism contracts to reduce the width dimension. When it is necessary to lift the goods, the transverse telescopic mechanism extends. After the width of the device is increased, it moves to the area where the goods are located, and the goods are lifted and transported in cooperation with the vertical telescopic part and the lifting lugs. The passing performance and loading performance of the device are improved by the transverse telescopic mechanism, etc., and it can flexibly adapt to various factory environments and better meet the use requirements.

[0017] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will be described in detail with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] like Figure 1 , Figure 2As shown, an embodiment of the present invention provides a transverse telescopic mechanism of a high seas railway intermodal loading and unloading device, wherein the high seas railway intermodal loading and unloading device is mainly composed of two sets of frame structures 1 arranged opposite to each other, and the frame structure 1 includes a lower beam 2, an upper beam 3, and a vertical telescopic part connecting the lower beam 2 and the upper beam 3. A running part 4 is provided at the bottom of the lower beam 2, so that the device can move on the road surface, and a vertical telescopic part 5 enables the upper beam 3 to be raised and lowered relative to the lower beam 2. A lifting lug 6 is also provided on the upper beam 3, and the cargo is fixed by the lifting lug 6, and the cargo is lifted under the action of the vertical telescopic part 5 to transport the cargo.

[0019] The transverse telescopic mechanism is arranged between the two frame structures 1, and includes a telescopic crossbeam 7 and a crossbeam guide sleeve 8 which are sleeved together. The outer end of the telescopic crossbeam 7 is fixedly connected to the upper beam 3 of one frame structure 1, and the outer end of the crossbeam guide sleeve 8 is fixedly connected to the upper beam 3 of the other frame structure 1. The telescopic crossbeam 7 can slide relative to the crossbeam guide sleeve 8 to guide the transverse movement of the two upper beams 3 and the frame structure 1, and is driven by a transverse telescopic oil cylinder 9. Among them, the bottom end of the transverse telescopic oil cylinder 9 is hinged to one upper beam 3, and the end of the piston rod is hinged to the other upper beam 3. The telescopic action of the piston rod of the transverse telescopic oil cylinder 9 controls the sliding distance of the telescopic crossbeam 7 relative to the crossbeam guide sleeve 8.

[0020] When the device is moving in an unloaded state, the transverse telescopic mechanism is in a retracted state, at which time the telescopic crossbeam 7 is inserted into the deepest distance of the crossbeam guide sleeve 8, and the device has a minimum width value, which can smoothly pass through narrow intersections. When the device needs to load cargo, the telescopic crossbeam 7 gradually extends relative to the crossbeam guide sleeve 8, and the distance between the two upper side beams 3 increases. At this time, the running parts 4 on both sides turn 90 degrees respectively, so that the two frame structures 1 move outward respectively, and the distance gradually increases, so that the device can move to the position where the cargo is located to prepare for lifting.

[0021] In this embodiment, two groups of transverse telescopic mechanisms are arranged, which are respectively located at the two ends of the upper beam 3. In addition, a connecting beam 10 is fixedly arranged between the two transverse beam guide sleeves 8. At the same time, the middle part of the connecting beam 10 is connected to the upper beam 3 on the same side of the transverse beam guide sleeve 8 through a connecting sub-beam 11. The supporting structure composed of the connecting beam 10 and the connecting sub-beam 11 further enhances the overall stability between the two transverse telescopic mechanisms.

[0022] Since the telescopic beam 7 will inevitably tilt to a certain extent during its sliding relative to the beam guide sleeve 8, especially when the telescopic beam 7 extends out of the beam guide sleeve 8 for a long distance, the relative displacement between the two frame structures 1 will cause the inner end of the beam guide sleeve 8 to be subjected to concentrated force, and the cyclic stress during long-term use will easily cause structural fatigue damage. Therefore, in this embodiment, a plurality of reinforcing plates 12 are arranged on the outer side wall of the inner end of the beam guide sleeve 8 to enhance the structural strength of the inner end of the beam guide sleeve 8.

[0023] In this embodiment, a limit plate 13 is further provided on the outer side wall of the telescopic beam 7, and the limit plate 13 limits the deepest distance of the telescopic beam 7 inserted into the beam guide sleeve 8, thereby limiting the shortest distance between the two frame structures 1, that is, the narrowest width of the device, and preventing the distance from being too close or even collision from causing structural damage due to reasons such as failure of the oil cylinder when the frame structures 1 are close to each other. Preferably, the limit plate 13 is located close to the outer end of the telescopic beam 7 to ensure that the width of the device can be reduced to a sufficiently narrow width, thereby having excellent narrow pass performance.

[0024] 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.
