Description

Technical Field

[0001] This utility model relates to the field of stacker crane equipment technology, and in particular to a current collector arm bracket and current collector arm for a stacker crane. Background Technology

[0002] Stacker cranes are the core handling equipment in modern intelligent warehousing, primarily performing functions such as outbound, inbound, sorting, and turnover. The high efficiency, low cost, and wide operational range of stacker cranes represent a future trend of continuous development. In conventional stacker crane designs, the collector arm support is typically welded together as a single unit. Due to limited space and the shape limitations of the collector arm itself, the entire installation assembly is difficult to install smoothly onto the extension support, usually requiring two workers and a significant amount of time to complete the installation.

[0003] In response to the above situation, the relevant technology has changed to using an "L-shaped" bending plate. However, after the stacker crane has been running for a long time, the contact between the current collector arm body and the sliding contact line is not close. Furthermore, the "L"-shaped bending plate is prone to deformation after long-term use, which will make the problem of the current collector arm body and the sliding contact line not being in close contact even more serious.

[0004] As stacker cranes become increasingly standardized, the design of current collector arm supports has become more solidified, leading to these problems remaining unresolved for a long time. Utility Model Content

[0005] In response to the shortcomings of the existing production technology, the applicant provides a current collector arm bracket and current collector arm for a stacker crane, which has a stable structure, ensures good contact between the current collector arm body and the sliding contact line, and allows for independent ground-based installation of the current collector arm, without being affected by limited space or the shape of the current collector arm body.

[0006] The technical solution adopted in this utility model is as follows: A current collector arm support for a stacker crane, comprising:

[0007] The first bending plate is configured as a U-shaped bending structure and is arranged in the vertical direction. The first bending plate includes a bending body. The upper side of the bending body is provided with a notch, and the lower side is provided with a through hole that communicates with the notch.

[0008] A square steel bar is provided, which penetrates the notch and the through hole, and one end of the square steel bar is used for assembly and connection with the main body of the current collector arm;

[0009] A connecting plate is fixed at the notch to confine the square steel within the notch, and the connecting plate is provided with multiple fixing components.

[0010] The fixing component includes a screw, an elastic washer, and a flat washer. The elastic washer and the flat washer are sequentially sleeved on the screw and fixed to the first bent plate by the screw passing through the connecting plate.

[0011] The second bending plate is arranged horizontally and fixed to the back side of the first bending plate for assembly and connection with the stacker crane extension bracket.

[0012] As a further improvement to the above technical solution:

[0013] Preferably, the width of the notch matches the cross-sectional width of the square steel, and the diameter of the through hole is greater than the cross-sectional width of the square steel.

[0014] Preferably, the connecting plate is also assembled and fixed to the first bending plate on both sides of the notch by a fixing component.

[0015] Preferably, the second bending plate is fixed to the first bending plate by welding, and the bending direction of the second bending plate is perpendicular to the bending direction of the first bending plate.

[0016] Preferably, the elastic washer is a rubber washer or a spring washer.

[0017] On the other hand, this utility model also provides a current collector arm for a stacker crane, including a current collector arm body, the current collector arm body being connected to the aforementioned current collector arm bracket via square steel, and the other side of the current collector arm body being in contact with a sliding contact line.

[0018] Preferably, the contact surface between the current collector arm body and the sliding contact line is arc-shaped or planar.

[0019] Preferably, the main body of the current collector arm is made of copper alloy or a metal material with a silver-plated surface.

[0020] Preferably, an insulating layer is added to the connection contact end between the current collector arm body and the square steel.

[0021] The beneficial effects of this utility model are as follows:

[0022] This utility model has a compact structure and is easy to operate. By using a split U-shaped first bending plate connected to square steel, and opening notches and through holes in the first bending plate, and with the help of detachable fixing components (screws, elastic washers, flat washers), the main body of the collector arm can be independently assembled on the ground, completely getting rid of the limitation of working in narrow spaces, and significantly reducing the difficulty of installation and labor costs.

[0023] This utility model also has the following advantages:

[0024] (1) The first bending plate of this utility model has a U-shaped structure and a second bending plate extending horizontally is welded and fixed on the back side, and the second bending plate is assembled and connected with the stacker crane extension bracket; the whole forms a three-dimensional support frame, which disperses stress and effectively suppresses deformation caused by vibration or load during long-term operation.

[0025] (2) The buffering effect of the elastic washer in the fixing component of this utility model can adaptively adjust the preload of the screw (4), offset the small displacement caused by equipment vibration or thermal expansion and contraction, maintain stable electrical contact between the current collector arm and the sliding contact line, and reduce the risk of sparks or power outages.

[0038] like Figures 1-5 The accompanying drawing shows a schematic diagram of the structure of a current collector arm support and a current collector arm for a stacker crane according to an embodiment of the present invention; for ease of description, the drawing only shows the structure related to the embodiment of the present invention.

[0039] In this embodiment, a current collector arm support for a stacker crane is provided, comprising:

[0040] The first bending plate 1 adopts a U-shaped bending structure and is set in the vertical direction. The upper side of its bending body 101 has a notch 102 and the lower side has a through hole 103 that passes through the notch 102. The width of the notch 102 matches the cross-sectional width of the square steel 2, and the diameter of the through hole 103 is slightly larger than the cross-sectional width of the square steel 2 so that there is an adjustment gap when the square steel 2 is installed through.

[0041] Square steel 2 passes through notch 102 and through hole 103, with one end connected to the current collector arm body 8 and the other end fixed by connecting plate 3. The cross-sectional shape of square steel 2 is preferably rectangular to enhance structural stability.

[0042] The connecting plate 3 covers the notch 102 and is fixed to the first bent plate 1 by a fixing assembly consisting of screws 4, elastic washers 5, and flat washers 6. The two side edges of the connecting plate 3 extend to the first bent plates 1 on both sides of the notch 102 and are further reinforced by multiple fixing assemblies to ensure that the square steel 2 does not shift within the notch 102.

[0043] The fixing component includes a screw 4, an elastic washer 5, and a flat washer 6; wherein the screw 4 passes through the connecting plate 3, the flat washer 6, and the elastic washer 5 in sequence, and engages with the threaded hole of the first bending plate 1 to lock it in place.

[0044] Furthermore, the elastic washer 5 is preferably a rubber washer or a spring washer, used to buffer vibration and adaptively adjust the preload.

[0045] The second bending plate 7 is arranged in a horizontal direction and welded to the back side of the first bending plate 1. Its bending direction is perpendicular to the U-shaped bending direction of the first bending plate 1. The end of the second bending plate 7 is provided with an assembly hole for connecting to the stacker crane extension bracket 10 by bolts.

[0046] In other embodiments, a current collector arm for a stacker crane is also provided, comprising:

[0047] The main body 8 of the current collector arm is fixedly connected to one end of the square steel 2, and its other side is attached to the sliding contact line 9.

[0048] Furthermore, the contact surface of the current collector arm body 8 is designed as an arc or planar structure, preferably using copper alloy or silver-plated metal material to improve conductivity.

[0049] Furthermore, an insulation layer is added to the connection end between the current collector arm body 8 and the square steel 2 to avoid the risk of leakage.

[0050] The sliding contact line 9 is arranged along the stacker crane's running track and maintains stable contact with the current collector arm body 8 to ensure the continuity of current transmission.

[0051] The stacker crane extension bracket 10 is assembled with the second bending plate 7 by bolts to provide overall support for the collector arm bracket.

[0052] In practical applications, the installation process of this utility model is as follows:

[0053] Ground-mounted pre-installed collector arm body 8 and square steel 2:

[0054] Insert one end of the square steel 2 into the mounting hole of the current collector arm body 8 and fix it by welding or bolts to ensure a firm connection; apply insulating material to the contact end between the square steel 2 and the current collector arm body 8 to form an insulating layer;

[0055] Assemble the first bending plate 1 and square steel 2:

[0056] The other end of the square steel 2 is passed through the notch 102 and the through hole 103 in sequence, so that the cross section of the square steel 2 matches the width of the notch 102, and the diameter of the through hole 103 provides installation allowance; the connecting plate 3 is placed over the notch 102, and the screw 4 is passed through the hole of the connecting plate 3. The flat washer 6 and the elastic washer 5 are then inserted in sequence, and finally screwed into the threaded hole of the first bending plate 1 to lock it; the above steps are repeated to install multiple fixing components on the first bending plate 1 on both sides of the notch 102 to further restrict the displacement of the square steel 2.

[0057] Welding the second bending plate 7:

[0058] The second bending plate 7 is horizontally welded to the back side of the first bending plate 1 to ensure that the bending directions of the two are perpendicular, forming a three-dimensional support frame; after welding, the weld is ground to avoid stress concentration.

[0059] Assemble the entire assembly into the stacker crane extension bracket 10:

[0060] Align the assembly hole at the end of the second bending plate 7 with the corresponding hole of the stacker crane extension bracket 10 and tighten it with bolts; adjust the position of the current collector arm body 8 so that it is fully in contact with the contact surface of the sliding contact line 9, and compensate for the small displacement caused by vibration or thermal expansion and contraction through the buffering effect of the elastic washer 5.

[0061] The present invention has a reasonable structure. By using the U-shaped first bending plate 1 in conjunction with the detachable square steel 2 and connecting plate 3, the ground pre-installation of the current collector arm body 8 can be achieved, avoiding the risks of high-altitude operations and significantly improving installation efficiency. At the same time, the three-dimensional frame formed by the second bending plate 7 and the first bending plate 1 disperses mechanical stress and suppresses deformation during long-term use. The buffering effect of the elastic washer 5 maintains the pre-tightening force of the screw 4 and can also ensure stable contact between the current collector arm body 8 and the sliding contact line 9.

[0062] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] The embodiments described above merely illustrate the implementation of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
