Description

Technical Field

[0001] The utility model belongs to the field of logistics transmission, in particular to a transport trolley, a hanging logistics device and a fluorescence detection assembly line. Background Art

[0002] During fluorescent penetrant testing, parts are transported to various functional areas via suspended flow lines for immersion in fluorescent penetrant, cleaning, or drying. A suspended assembly line is a three-dimensional, closed-loop, continuous material conveying system suitable for automated transport of finished items within and between workshops. It is typically suspended from a workshop ceiling or mounted on a floor stand, running along a predetermined track.

[0003] Due to the requirements of workshop space distribution, a certain section of track will be designed with a certain slope and curvature. Since the driven wheel assembly of the transport trolley is fixedly connected to the vehicle body and has a limited range of motion, when the transport trolley passes through a guide rail with a large slope or curvature, the movement direction of the front and rear driven wheels will not be adjusted in time, causing the transport trolley to get stuck on the guide rail, affecting the transportation rhythm and efficiency of the entire assembly line.

[0004] Therefore, it is necessary to provide a transport trolley, a suspended logistics device and a fluorescence detection assembly line to overcome the above-mentioned defects. Utility Model Content

DETAILED DESCRIPTION

[0026] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following briefly introduces the drawings required for use in the embodiments or the description of the prior art. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0027] See also Figure 1 This embodiment discloses a suspended logistics device, which is mainly used in fluorescent non-destructive testing production lines. The suspended logistics device includes two lower guide rails 200 that are suspended and spaced apart by a predetermined distance, a carrying trolley 100 placed on the two lower guide rails 200, and a driving device that drives the carrying trolley 100 to move along the guide rails. The driven wheel assembly can move along the lower guide rails 200.

[0028] The driving device includes a circular guide rail 300, which is distributed in a triangle with the two lower guide rails 200, and the circular guide rail 300 is located at the upper vertex and can rotate along the central axis of the circular guide rail 300. The driving wheels 150 on the upper part of the carrying trolley 100 are installed obliquely symmetrically, and the driving wheels 150 are multiple driving wheels 150 that are abutted against both sides of the outer surface of the circular guide rail 300. The rotation axis of the driving wheel 150 is inclined at a predetermined angle relative to the horizontal plane, and is inclined inward at a predetermined angle relative to the vertical plane where the central axis of the circular guide rail 300 is located.

[0029] When the circular guide rail 300 rotates, the driving wheel 150 can be driven to rotate by friction, and the driving wheel 150 is inclined to the transmission direction of the motion device, which can be decomposed into a force moving along the transmission direction of the motion device. Therefore, the carrying trolley 100 can move linearly along the lower guide rail 200. The specific structure and related principles can be found in the prior application CN217755467U.

[0030] Of course, for those skilled in the art, there are many ways to implement the driving device. For example, the driving device includes a closed transmission chain arranged above the lower guide rail 200 and a chain plate arranged on the transport trolley 100 and connected to the transmission chain. The movement of the transport trolley 100 is achieved by the rotation of the transmission chain.

[0031] Due to the spatial distribution requirements of the inspection workshop, the guide rails of the suspended logistics device will be designed to have a certain slope and curvature. Since the driven wheel assembly of the transport trolley 100 is fixedly connected to the vehicle body 110, the range of movement is limited. When the slope or curvature of the guide rail is too large, the movement direction of the front and rear driven wheels 170 will not be adjusted in time, which will cause the transport trolley 100 to be stuck on the guide rail, affecting the transportation rhythm and inspection efficiency of the entire assembly line.

[0032] This embodiment improves the structure of the conventional transport vehicle 100 to overcome the above problems. Figures 2 to 4 This embodiment provides a transport vehicle 100 , including: a vehicle body 110 , a driven wheel assembly and a pin shaft 180 .

[0033] Two mounting plates 120 are provided below the vehicle body 110 with a predetermined interval therebetween; wherein, the driven wheel assembly includes a support plate 140 provided below the mounting plate 120, a rubber block 130 provided on the upper part of the support plate 140 and clamped between the mounting plates 120, two mounting shafts 160 fixed at the front and rear ends of the support plate 140, and driven wheels 170 respectively provided at both ends of the mounting shaft 160; the pin shaft 180 passes through one mounting plate 120, the rubber block 130 and the other mounting plate 120, thereby realizing the pin shaft 180 for rotationally connecting the support plate 140 with the vehicle body 110.

[0034] Since the rubber block 130 has a certain degree of deformation ability, through the assembly of the rubber block 130 and the pin shaft 180, the rubber block 130 can realize the swing of the driven wheel 170 group in the left and right directions. When the carrying trolley 100 passes through the guide rail with a large slope or curvature, the movement direction of the driven wheel 170 group can be adjusted in time, which can greatly improve the passing performance of the carrying trolley 100 and prevent the carrying trolley 100 from getting stuck on the guide rail, thereby ensuring the transportation rhythm and detection efficiency of the entire fluorescence detection line.

[0035] The driven wheel assembly includes a first driven wheel assembly disposed at the front end of the mounting plate 120 and a second driven wheel assembly disposed at the rear end of the mounting plate 120. Specifically, a first mounting hole is provided at the front end of the mounting plate 120, a second mounting hole is provided at the rear end of the mounting plate 120, and a third mounting hole 132 is provided on the rubber block 130. The pin 180 passes through the first and third mounting holes 132 to install the first driven wheel assembly, and the pin 180 passes through the second and third mounting holes 132 to install the second driven wheel assembly. In other words, the traditional four-wheeled cart is designed as an eight-wheeled cart, resulting in enhanced overall transport performance and further ensuring the transportation rhythm and detection efficiency of the entire fluorescence detection line.

[0036] In a further embodiment, two end caps 131 are provided on either side of the rubber block 130, and the two end caps 131 respectively have a clearance fit with the two mounting plates 120. The two end caps 131 are fixedly connected to the rubber block 130 by adhesive or bolts. This prevents direct contact between the rubber block 130 and the two mounting plates 120 when the driven wheel 170 assembly swings left and right, thereby reducing wear on the rubber block 130.

[0037] In a further embodiment, conical grooves 133 are provided on both sides of the rubber block 130 near the pin shaft 180 to provide avoidance space for the driven wheel 170 group to swing in the left and right directions, thereby avoiding excessive friction between the rubber block 130 and the pin shaft 180 and causing wear of the rubber block 130.

[0038] In a further embodiment, a suspension assembly 400 is further disposed below the vehicle body 110. A fourth mounting hole 121 is further disposed in the center of one mounting plate 120, and the suspension assembly 400 is fixedly mounted in the fourth mounting hole 121. The suspension assembly 400 includes a connecting rod fixedly mounted in the fourth mounting hole 121 and extending through the predetermined gap between the two lower guide rails 200, and a clamping portion disposed at the bottom of the connecting rod. The clamping portion clamps the workpiece to be processed, thereby securing the workpiece to be inspected.

[0039] It will be apparent to those skilled in the art that various modifications and variations can be made to the exemplary embodiments described above without departing from the spirit and scope of the present invention. Therefore, it is intended that the present invention cover modifications and variations of the present invention that fall within the scope of the appended claims and their equivalents.
