Description

Technical Field

[0001] This utility model relates to the field of crane technology, and in particular to a crane trolley guiding device for use in small space scenarios. Background Technology

[0002] Bridge cranes are lifting equipment that spans across workshops, warehouses, and material yards for material handling. Their ends rest on tall concrete pillars or metal supports, resembling a bridge. The bridge frame of the bridge crane runs longitudinally along tracks laid on elevated structures on both sides, making full use of the space beneath the bridge frame for material handling without being obstructed by ground equipment. It is the most widely used and numerous type of lifting machinery.

[0003] Guide wheels are crucial structures that ensure the stable operation of a crane trolley along the tracks on the bridge frame. During installation, the distance between the guide wheels and the tracks needs to be fine-tuned to prevent excessive spacing from affecting the stability of the trolley's operation. When cranes are used in small spaces such as workshops or warehouses, the fine-tuning of the guide wheels is inconvenient due to space constraints. Utility Model Content

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0029] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] Please refer to Figures 1-6This utility model provides a crane trolley guiding device for use in small space scenarios, including a bracket 1; guide wheel frames 2 are symmetrically arranged on both sides of the guide rail below the bracket 1; the guide wheel frames 2 are connected to the bracket 1 through an adjustment component 3 to adjust the distance between the guide wheel frames 2 and the guide rail; guide wheels 4 are symmetrically arranged on both sides of the guide rail; the guide wheels 4 are detachably rotatably connected to the guide wheel frames 4 on the same side through a connecting component 5; a buffer component 6 is fixedly arranged at one end of the bracket 1 along the length of the rail.

[0031] In this embodiment, the crane trolley is located on two guide rails of the bridge frame. The guide devices of this application are respectively installed at both ends of the end beam 7 of the crane trolley. The guide wheel 4 is detachably and rotatably mounted on the guide wheel frame 2 through the connecting component 5. The guide wheel frame 2 is connected to the bracket 1 through the adjusting component 3. The distance between the guide wheel frame 2 and the guide rail can be adjusted by the adjusting component 3, thereby realizing the fine adjustment of the distance between the guide wheel 4 and the guide rail, so that the guide wheels 4 on both sides of the guide rail are closely fitted to it, ensuring the stability of the equipment operation.

[0032] When the guide wheel 4 is severely worn and needs to be replaced, the entire guide device does not need to be disassembled. The guide wheel 4 can be removed and replaced by disassembling the connecting component 5. The guide wheel 4 is easy to replace, which greatly reduces the downtime of the equipment and ensures production efficiency. When the guide device is about to collide with the wall or other structure in the workshop or warehouse, the buffer component 6 can effectively prevent the guide device from being damaged by the collision, play a protective role, and improve the safety of equipment operation.

[0033] In a preferred embodiment, such as Figure 1 and Figure 2 As shown, a first flange 11 is fixedly installed at the end of the bracket 1 away from the buffer assembly 6. The bracket 1 is fixedly connected to the end beam 7 through the first flange 11, which is convenient to install and secure.

[0034] In a preferred embodiment, such as Figure 3 and Figure 4 As shown, the adjustment assembly 3 includes a connecting shaft 31 rotatably mounted on the bracket 1. A first shaft end baffle 32 is provided at the top of the connecting shaft 31. The first shaft end baffle 32 is fixedly connected to the connecting shaft 31 by a first bolt 33. Several through holes 34 are evenly distributed along the circumference of the first shaft end baffle 32. A second bolt 35 passes through the through holes 34 and is threadedly connected to the bracket 1. An eccentric shaft 36 is fixedly provided at the bottom of the connecting shaft 31. The eccentric shaft 36 is rotatably connected to the guide wheel frame 2 by a bushing 37.

[0035] In this embodiment, the eccentric shaft 36 and the connecting shaft 31 are eccentrically distributed. After removing the second bolt 35, rotating the connecting shaft 31 will cause the eccentric shaft 36 to rotate accordingly. Due to the eccentric relationship, the eccentric shaft 36 will cause the guide wheel frame 2 to move closer to or further away from the guide rail, thereby adjusting the distance between the guide wheel 4 and the guide rail. After the adjustment is completed, the first shaft end baffle 32 can be re-fixed to the bracket 1 using the second bolt 35.

[0036] The adjustment precision of the spacing can be controlled through two structural designs: firstly, the number of through holes 34—the more through holes 34 there are, the smaller the minimum adjustable angle and the higher the adjustment precision; and secondly, the eccentricity between the eccentric shaft 36 and the connecting shaft 31—the larger the eccentricity, the wider the adjustable range but the lower the adjustment precision; conversely, the smaller the eccentricity, the smaller the adjustable range but the higher the adjustment precision. These two structural designs ensure that the fine-tuning of the guide wheel 4 meets the requirements.

[0037] In a preferred embodiment, such as Figure 3 and Figure 5 As shown, the connecting assembly 5 includes a wheel axle 51 and a second shaft end baffle 52. A bearing is fixedly installed inside the guide wheel 4. The wheel axle 51 passes through the bearing with clearance fit. The bottom end of the wheel axle 51 is separably embedded in the guide wheel frame 2, and the top end passes through the guide wheel frame 2. The second shaft end baffle 52 is fixedly connected to the wheel axle 51 by a third screw 53 and fixedly connected to the guide wheel frame 2 by a fourth screw 54.

[0038] In this embodiment, when replacing the guide wheel 4, the second shaft end baffle 52 and the wheel axle 51 can be pulled off together by unscrewing the fourth screw 54. At this time, the guide wheel 4 is removed from the guide wheel frame 2, and the new guide wheel 4 is placed into the guide wheel frame 2. Then, the wheel axle 51 is inserted and passes through the bearing in the guide wheel 4. Finally, the second shaft end baffle 52 is fixedly connected to the guide wheel frame 2. The replacement of the guide wheel 4 is very convenient.

[0039] In a preferred embodiment, such as Figure 2 and Figure 4 As shown, the wheel axle 51 is inclined from top to bottom in the vertical direction away from the guide rail.

[0040] In this embodiment, the inclined axle 51 causes the guide wheel 4 to be inclined relative to the guide rail, which can distribute the load to enhance the anti-skewness capability, improve dynamic stability, reduce fatigue of the guide wheel 4, reduce track maintenance costs, and extend equipment life.

[0041] In a preferred embodiment, such as Figure 1As shown, the buffer assembly 6 includes a support plate 61 fixedly disposed at one end of the bracket 1. An extension rod 62 parallel to the guide rail is fixedly disposed on the plate surface of the support plate 61 away from the bracket 1. Several reinforcing plates 63 are fixedly disposed between the extension rod 62 and the support plate 61. A hydraulic buffer 65 is fixedly connected to the end of the extension rod 62 away from the support plate 61 through a second flange 64.

[0042] In this embodiment, the hydraulic buffer 65 is installed at one end of the bracket 1 via the extension rod 62. When the crane trolley moves, the hydraulic buffer 65 will first hit the obstacle to buffer it, effectively preventing the guide wheel 4 from directly hitting the obstacle and being damaged, thus ensuring the safety of the equipment operation.
