Description

Technical Field

[0001] The invention belongs to the technical field of rail recovery roller beams, and in particular relates to a layered adjustable flat rail bearing roller beam assembly. Background Art

[0002] When long rail vehicles are used for collecting, changing and unloading rails, the roller beam device is a special equipment for carrying long rails. Usually, the roller beam has several layers. When collecting or unloading any layer of rails, it is necessary to open the roller beam of the layer above it. The roller beam is usually a beam with a fixed axis at one end. It can be opened or closed by horizontally rotating 90°. The free end of the beam is stably supported by a fixed structure in the fully open or closed state.

[0003] There are currently two types of roller beam rotating components. One is to fix the rotating shaft between the upper and lower adjacent partitions of the roller beam rotating shaft column, and then the rotating sleeve is mounted on the rotating shaft through a sliding sleeve.

[0004] The following defects exist: Since the shaft is fixed between the column compartments, the vertical height can only be slightly adjusted through the assembly gap between the shaft and the sleeve, and these gaps are very difficult to adjust and are easily changed during use, causing the raceway beam to sag. Due to the need to install the shaft, the column compartment splicing accuracy of the welded structure is very high, which is difficult to ensure in terms of technology, and easily leads to the shaft being misaligned. In long-term use, the welded compartments are prone to deformation, resulting in changes in the hanging height of each layer of beams, and the beams themselves have no adjustment ability, resulting in permanent height changes.

[0005] The second type is to use a structure where the rotating ends of the beams of each layer share the same rotating shaft. The rotating shaft has a sufficient length, and each layer of roller beams is sleeved on this rotating shaft layer by layer. The rotating shaft is connected to the column, the lower end is fixed, and the upper end is detachable. When assembling, start from the lower layer, and insert the roller beams of each layer from the upper part of the rotating shaft in turn.

[0006] The following defects exist: the crossbeam of the raceway beam is welded and fixed to the rotating sleeve and has no adjustment capability; the crossbeams of each layer of the raceway beam are installed on the same rotating shaft, and the rotating shaft and each layer of the shaft sleeve are installed with bearings, and there is no assembly gap. The overhang of the free end of the crossbeam of the raceway beam can only be adjusted by adjusting the angle of the rotating shaft. Therefore, the crossbeams of each layer of the raceway beam cannot be adjusted individually and must be adjusted at the same time. Summary of the invention

[0007] The present invention aims to provide a layered adjustable flat rail roller beam assembly, which can flexibly adjust the height of the overhanging end of the roller beam up and down, and solve the problem that the height of a single-layer roller beam cannot be adjusted due to fixing the rotating shaft between the upper and lower adjacent partitions of the roller beam rotating shaft column, and using the rotating ends of each layer of cross beams sharing the same rotating shaft.

[0008] To this end, the technical solution adopted by the present invention is: a layered adjustable level rail roller beam assembly, including a roller beam bracket column, a roller beam shaft column, several layers of roller beams spaced apart from each other, and roller beam rotation components corresponding to the roller beams one by one, and a roller beam lock. The right end of the roller beam is connected to the roller beam shaft column through the roller beam rotation component, so as to realize the horizontal rotation of the roller beam in the transverse and longitudinal directions. The roller beam shaft column is "H"-shaped and the middle beam column is spaced apart from each other with a rotation component mounting table. The roller beam rotation component includes a rotating shaft, a shaft sleeve mounted on the rotating shaft through a bearing sleeve spaced apart from each other, and a rotating shaft mounting seat located at the top of the rotating shaft. The middle section of the shaft sleeve is provided with a mounting vertical platform welded to the end of the roller beam. The mounting seat includes a vertical mounting base fixed on the middle beam column of the roller beam shaft column by bolts and a horizontal roller shaft mounting plate provided with a square hole. The top of the shaft is provided with a square column matching the size of the square hole, and the bottom is provided with a lower shaft mounting seat bolted to the rotating component mounting platform. The bolt on the left side between the lower shaft mounting seat and the rotating component mounting platform is equipped with an angle adjustment washer, so that the inclination of the roller beam can be adjusted by adding an angle adjustment washer to keep the roller beam in a horizontal state. The roller beam lock includes a mounting base fixed on the side beam of the roller beam shaft column and a locking hook hingedly mounted on the mounting base. When the locking hook rotates 270° counterclockwise from a vertical state to a horizontal state, it can hook the upper part of the longitudinal roller beam crossbeam, thereby locking the roller beam.

[0009] As a preferred embodiment of the above scheme, annular bosses for installing bearings are provided at intervals above and below the rotating shaft body, and the bearings located at the upper part of the rotating shaft body adopt deep groove ball bearings, and the bearings located at the lower part of the rotating shaft body adopt deep groove ball bearings and thrust bearings arranged up and down. Bearings are provided on the upper and lower parts of the rotating shaft body to ensure smooth rotation of the rotating sleeve and eliminate the height difference caused by the gap between the rotating sleeve and the rotating shaft.

[0010] Further preferably, the mounting base includes a horizontal bottom plate fixed on the side beam of the roller beam shaft column and a locking hook mounting vertical plate fixed on the horizontal bottom plate at front and rear intervals. The locking hook is hinged between the locking hook mounting vertical plates. A transverse notch is provided on the right side of the horizontal bottom plate for the locking hook to rotate counterclockwise. The design is reasonable, and the transverse notch effectively ensures the smooth counterclockwise rotation of the locking hook.

[0011] Further preferably, the square column passing through the square hole is connected to the mounting seat on the rotating shaft by adjusting bolts, and a sealing cover is installed on the top surface of the square column by screws, so that the square column is fixed to the mounting seat on the rotating shaft from two directions to ensure the stability of the square column installation, thereby ensuring the stability of the upper part of the rotating shaft.

[0012] More preferably, the lower shaft mounting seat is provided with bolt mounting holes around its circumference, and a vertical surface parallel to the middle beam of the roller beam shaft column is provided on the right side, so as to effectively avoid the lower shaft mounting seat from interfering with the middle beam of the roller beam shaft column. The design is reasonable.

[0013] Further preferably, strip-shaped bolt mounting holes are provided at the four corners of the vertical mounting base, which effectively increase the flexibility of installation and adjustment, and longitudinally adjust the installation position of the vertical mounting base, thereby adjusting the longitudinal installation orientation of the raceway beam and crossbeam. A reinforced triangular rib plate is provided at the junction of the vertical mounting base and the horizontal rotating shaft mounting plate to increase structural stability.

[0014] Beneficial effects of the present invention:

[0015] (1) Compared with the method of fixing the rotating shaft between the upper and lower adjacent partitions of the rotating shaft column of the roller beam, and using the rotating ends of each layer of beams to share the same rotating shaft, which makes it impossible to adjust the height of a single-layer roller beam, this solution installs the roller beam in layers, and the mounting seat on the rotating shaft is fixed to the middle beam column of the rotating shaft column of the roller beam by bolts, and the square column on the top of the rotating shaft is installed on the horizontal rotating shaft mounting plate of the mounting seat on the rotating shaft, so that the mounting point at the top of the rotating shaft is adjusted from the original vertical direction to the horizontal horizontal direction, so that there is enough space to finely adjust the installation position of the rotating shaft. The installation base structure of the top of the rotating shaft is fixed horizontally, which has strong anti-deformation ability and ensures installation accuracy.

[0016] (2) The shaft sleeve and the rotating shaft are connected by bearings arranged at intervals above and below, rather than being directly mounted, which effectively reduces the force required for the horizontal rotation of the raceway beam. The design is reasonable and saves time and effort.

[0017] (3) The initial state of the lock hook is vertical. When the roller beam rotates to the longitudinal direction, the lock hook rotates 270° counterclockwise to the horizontal state, and can hook the upper part of the longitudinal roller beam crossbeam, thereby locking the roller beam. The design is ingenious, and the counterclockwise rotation path of the lock hook avoids the roller beam, so there will be no collision, and the operation is simple and flexible.

[0018] (4) Since there is no support point at the other end of the roller beam when it rotates, the overhanging end of the roller beam cannot remain horizontal due to the influence of gravity. An angle adjustment washer is added between the mounting seat under the rotating shaft and the rotating component mounting platform. The inclination of the roller beam can be flexibly adjusted to balance the gravity so that the roller beam can remain horizontal when it rotates. The height of the overhanging end of the single-layer roller beam can be flexibly adjusted. The design is exquisite and reduces the difficulty of assembling and debugging the roller beam.

[0019] In summary, it has the advantages of high installation accuracy, reasonable design, time and labor saving, simple lock hook operation, and flexible adjustment of the height of the overhanging end of the single-layer raceway beam. BRIEF DESCRIPTION OF THE DRAWINGS
