Description

Technical Field

[0001] The utility model relates to the technical field of rail four-way vehicle accessories, in particular to a wheel-rail docking structure of a rail four-way vehicle. Background Art

[0002] A rail-mounted four-way vehicle refers to a vehicle that can move in four directions, front, back, left, and right, along corresponding guide rails. When in use, the laying of the guide rails includes one or more transverse rails and one or more longitudinal rails. The transverse rails and the longitudinal rails are perpendicular to each other. However, when the rail-mounted four-way vehicle moves on the transverse rails and the longitudinal rails, since the wheels at the bottom of the four-way vehicle generally use wheels that can only move forward or backward, and do not use universal wheels, at this time, if the four-way vehicle wants to transform between the transverse rails and the longitudinal rails, it needs to use the corresponding wheel-rail docking structure, and use the wheel-rail docking structure to realize the transfer of the four-way vehicle from the transverse rails to the longitudinal rails, or from the longitudinal rails to the transverse rails.

[0003] The wheel-rail docking structure of the four-way rail vehicle on the market generally uses a track with a larger curvature to lay at the ends of the transverse guide rail and the longitudinal guide rail, so that when in use, the rollers at the bottom of the four-way rail vehicle can move along the transverse guide rail, the curvature guide rail and the longitudinal guide rail. However, when laying the guide rail with a larger curvature, due to the larger outer diameter of its cross-sectional circle, the track with a larger curvature will occupy a larger space. Especially when the space in the factory is limited, it is difficult to ensure the normal arrangement of the track with a larger curvature, which affects the use effect. In view of this, we proposed a wheel-rail docking structure for the four-way rail vehicle. Utility Model Content

[0004] The utility model aims to provide a wheel-rail joint structure for a track-bound four-way vehicle, so as to solve the defects mentioned in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] The wheel-rail docking structure of the rail-mounted four-way vehicle comprises two guide rails arranged transversely and two guide rails arranged longitudinally, wherein the guide rails are provided with slide grooves arranged along the length direction of the guide rails, and docking plates are provided at the ends of the four guide rails, and two mutually symmetrical slide-in grooves are provided on the docking plate, and the slide-in grooves are communicated with the corresponding slide grooves, and a driving assembly is provided at the bottom of the docking plate, and the driving assembly comprises a vertically arranged support column, and an annular groove is provided in the top column body of the support column, and a servo motor is fixedly installed on the bottom wall of the annular groove, and a limit plate is fixedly installed at the end of the output shaft of the servo motor, and the docking plate is fixedly installed on the upper surface of the limit plate.

[0007] Preferably, the docking plate is used to adjust the connection operation between the slide-in groove and the slide groove after rotation, the slide-in groove and the slide groove are at the same height, and the depth of the slide-in groove and the slide groove are equal, so that the rail four-way vehicle can move normally in the slide-in groove and the slide groove.

[0008] Preferably, a plurality of vertical rods arranged linearly and equidistantly are fixedly mounted on the bottom surface of the guide rail, and a bottom plate is fixedly mounted on the bottom end of the vertical rods, so as to facilitate supporting operations using the bottom plate and the vertical rods.

[0009] Preferably, a fixing plate is fixedly mounted on the bottom end of the support column, and the fixing plate is used for bolt insertion and fixing operations.

[0010] Preferably, an outer support sleeve is fixedly mounted on the top column of the support column, and the bottom surface of the docking plate abuts against the outer support sleeve for supporting operation.

[0011] Preferably, an annular limiting groove is provided on the top surface of the outer support sleeve, and a concentrically arranged inner ring and outer ring are fixedly installed on the bottom surface of the docking plate, the inner ring is located in the annular limiting groove and is rotatably connected to the annular limiting groove, and the outer ring is sleeved on the outer support sleeve and is rotatably connected to the outer support sleeve, thereby supporting the docking plate.

[0012] Preferably, a plurality of heat dissipation holes connected to the outside are arranged on the bottom wall of the outer support sleeve, and the heat dissipation holes are used for heat dissipation operation.

[0013] Preferably, a plurality of ventilation holes connected to the outside are arranged on the groove wall of the annular groove, and the ventilation holes are used for ventilation operation.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The utility model is provided with a docking plate and a driving assembly. As the vehicle moves from the horizontal guide rail to the docking plate, the driving assembly drives the docking plate to rotate 90 degrees, so that the slide-in groove is connected with the longitudinal slide groove. At this time, the rail four-way vehicle can move to the longitudinal guide rail to achieve the effect of docking operation. Compared with the guide rail with a larger curvature, the docking plate occupies less space, which is convenient for use in the factory, achieving the effect of facilitating wheel-rail docking.

[0016] 2. The utility model realizes the support operation of the docking plate through the outer support sleeve and the inner sleeve ring, and also facilitates the heat dissipation operation through the ventilation holes and heat dissipation holes. BRIEF DESCRIPTION OF THE DRAWINGS
