Description

Technical Field

[0001] The present application relates to a quick-hook device and a hook method for a control panel, and belongs to the technical field of aerial work vehicles. Background Art

[0002] The control panel in the bucket is typically riveted to the bracket, which is welded to the bucket interior. When the control panel is positioned rearward, meaning the operator faces the boom, they can clearly observe the boom's deployment and lowering in real time, allowing them to control or stop the boom as needed, effectively reducing the risk of an unexpected boom drop. However, during normal vehicle operations in this orientation, the operator faces their back to the target, unable to observe the surroundings and the specific location of the target. This makes it difficult to accurately determine the distance between the bucket platform and the target, hindering rescue operations. This is especially true when the platform approaches the target, posing a higher risk of collision. Conversely, if the control panel is positioned forward, meaning the operator faces the target, they can directly observe the surroundings and the target during operations, facilitating close-range operations. However, with this arrangement, the operator cannot observe the boom's position relative to the vehicle during retraction and extension. If the boom experiences any abnormality during retraction, it is difficult for the operator to detect it promptly, posing another safety risk.

[0003] The conventional control console is fixed in a single location within the work bucket, locking the operator's orientation. Given the typical layout of aerial work vehicles, the boom and target are typically located at the front and rear of the work bucket, respectively. This fixed installation prevents the operator from simultaneously observing both the boom's extended and retracted position and the target's status. Regardless of which viewing direction is chosen, the operator inevitably loses visibility in the other direction, introducing corresponding safety risks, significantly compromising safe operations, and impacting rescue efficiency. Summary of the Invention

[0004] The purpose of this application is to overcome the deficiencies in the prior art and to provide a quick-attachment device and method for a control panel to solve the technical problem that an operator cannot quickly adjust the operating position of the control panel.

[0005] In order to achieve the above objectives, the technical solution adopted in this application is: In a first aspect, the present application provides a console quick hitch device, comprising: The upper end of the support plate is provided with an upper hook for hanging the upper support rod of the working bucket. The baffle forms an adjustable U-shaped groove with the lower end of the support plate for hooking the lower support rod of the working bucket; The screw system includes a screw that passes through the support plate and the detection plate, a compression spring sleeved on the outer circumference of the screw, and a manual nut that drives the baffle to press the lower support rod; The detection system includes a detection plate, electrical components and screws of the test piece fixed to the fixed plate. The detection plate is slidably connected to the inside of the fixed plate. When the detection plate moves, it can change its relative position with the screws of the test piece, triggering the electrical components to switch states.

[0006] In combination with the first aspect, further, the support plate includes a plurality of support surfaces integrally formed or welded, including: The first supporting surface is used to fix the operating table; The second supporting surface is directly or indirectly connected to the first supporting surface and is provided with an opening for inserting the baffle; a third supporting surface connected to the second supporting surface and abutting against one end of the compression spring; The fourth supporting surface is horizontally arranged and vertically connected to the fifth supporting surface to form a lower set of hooks of the L-shaped structure, wherein the lower set of hooks and the baffle form an adjustable U-shaped groove; The fifth supporting surface is parallel to the baffle and the spacing therebetween is adjustable.

[0007] Furthermore, the upper portion of the baffle is fixed to the support plate, and the lower portion passes through the opening of the second support surface; Two ends of the compression spring respectively abut against the third supporting surface and the detection plate.

[0008] Furthermore, a wear-resistant part with a guide chamfer is provided on the inner side between the fifth supporting surface and the baffle.

[0009] Furthermore, the electrical component is a proximity switch or a travel switch, which is installed on a side of the detection plate away from the fourth supporting surface.

[0010] Furthermore, the screw system further comprises: The first anti-rotation baffle is fixed to the detection plate by fastening screws to limit the radial rotation of the screw; The second anti-rotation baffle is fixed to the detection plate by fastening screws to limit the axial movement of the screw.

[0011] In a second aspect, the present application provides a method for attaching a quick-attachment device for a console, comprising: Hang the upper set of hooks and adjustable U-shaped slots on the upper support rod and lower support rod respectively; Tighten the manual nut until the detection plate moves to the point where the electrical component detects the screw of the test piece and the alarm is released. At this time, the baffle presses the lower support rod; When the manual nut is loosened, the detection board resets, causing the electrical component to leave the detection range of the screw of the measured object, triggering an alarm.

[0012] In a third aspect, the present application provides a work bucket, wherein the front fence and / or rear fence of the work bucket are provided with an upper support rod and a lower support rod for cooperating with the quick-hook device of the operating platform described in the first aspect.

[0013] In a fourth aspect, the present application provides an aerial work vehicle comprising the working bucket described in the third aspect and the control panel quick-hook device described in the first aspect.

[0014] Compared with the prior art, the present invention has the following beneficial effects: In this application, the upper end of the support plate is set as an upper group of hooks, and the lower end and the baffle form an adjustable U-shaped groove. Through the two sets of hook-type control panel brackets and the work buckets with support rods at the front and rear, the control panel can be flexibly switched in front of and behind the work bucket.

DETAILED DESCRIPTION

[0016] The present application will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present application and are not intended to limit the scope of protection of the present application.

[0017] Example 1:

[0018] like Figure 2 As shown, the present application provides a quick-attachment device for a control console, comprising a support plate 2, a baffle plate 3, a fixing plate 4, a detection plate 5, a screw system 6, and a detection system 7. The support plate 2 and baffle plate 3 form two sets of hooks that can be attached to the fence of the work bucket 1. The screw system 6 enables the opening and closing of the lower hooks, and the detection system 7 enables real-time detection of the attachment. The control console 8 is fixed to the first support surface 23 at the upper portion of the support plate by fixing bolts and other fixing members, enabling the quick attachment of the control console.

[0019] like Figure 1 As shown, this is a schematic diagram of the hooking of a quick hooking device for the operating table provided in this embodiment. Two groups of square steel pipes are provided near the upper and lower fences in the front and rear of the working bucket 1, namely the upper support rod 11 and the lower support rod 12, which are used to cooperate with the hooking of the quick hooking device for the operating table to realize the overall hooking and support of the operating table 8.

[0020] The console quick-hook device is mainly supported by a support plate 2, which can be formed by bending a plate into an upper group of hooks 21, a first support surface 23, a second support surface 24, a third support surface 25, a fourth support surface 26 and a fifth support surface 27; or welded parts can be welded to have this structural feature, and different bending surfaces are used to achieve different functions, such as Figure 2 The upper hook group 21 of the support plate 2 adopts a fixed "U" structure with the opening facing downwards, and is used to cooperate with the upper support rod 11 of the fence.

[0021] The fourth supporting surface 26 is set horizontally, and the fifth supporting surface 27 is set vertically. The four supporting surfaces 26 and the fifth supporting surface 27 together constitute the lower group of hooks 22 of the L-shaped structure; wherein, the lower group of hooks 22 and the lower part of the baffle 3 form a "U"-shaped structural opening groove with the opening facing downward, which is used to cooperate with the lower support rod 12 of the fence.

[0022] The first supporting surface 23 is used to support the operating table 8. The first supporting surface 23 and the second supporting surface 24 are provided with connecting plates. The connecting plates can be formed by bending the same plate into one piece, or by welding them together.

[0023] The baffle 3 is arranged vertically, with the angle between the plane of the fifth support surface 27 and the plane of the baffle 3 being no greater than 30°; the angle between the plane of the second support surface 24 and the plane of the fourth support surface 26 being less than 90°. In this application, it is preferred that the plane of the fifth support surface 27 be parallel to the plane of the baffle 3, and the plane of the second support surface 24 be perpendicular to the plane of the fourth support surface 26.

[0024] An opening is provided on the second supporting surface 24, and the upper part of the baffle 3 is fixed to the supporting plate 2 by bolts, and the lower part is inserted into the opening on the second supporting surface 24, which plays the role of left and right limit, and can also realize the increase or decrease of the distance between the baffle 3 and the fifth supporting surface 27, so as to facilitate quick hanging and fixing with the lower support rod 12 of the fence.

[0025] The fixing plate 4 in the present application is a U-shaped structure with side edges of different lengths, and its side edges are respectively fixed on the third supporting surface 25 and the fifth supporting surface 27 in the supporting plate 2 to form a cavity, which is used to install the screw system 6 and the detection system 7.

[0026] It is feasible that a process hole for installing the shaft end limit of the screw system 6 is opened on the outer side of the fixing plate 4.

[0027] The detection plate 5 is fixed inside the fixing plate 4 to secure the screw system 6. The upper flange of the detection plate 5 is configured as an L-shaped structure, and the lower portion is configured as a U-shaped structure. The L-shaped structure is used to secure the electrical component 73, and the side of the L-shaped structure near the fourth support surface 26 can slide. The bottom surface of the lower U-shaped structure supports the screw system 6.

[0028] Alternatively, the detection plate 5 may be configured as four planes perpendicular to each other.

[0029] like Figure 3 、 Figure 4 As shown, there are left and right views of the screw system and the detection system respectively; The screw system 6 primarily consists of a screw 61, a compression spring 62, a first anti-rotation baffle 63, a second anti-rotation baffle 64, a manual nut 66, and a fastening screw 67. In this embodiment, the screw 61 is a hexagonal screw fastener, one end of which passes through the inspection plate 5 and is located in the process hole of the fixed plate 4. The first anti-rotation baffle 63 is provided in conjunction with the hexagonal structure of the end to prevent radial rotation of the screw 61. A second anti-rotation baffle 64 is provided on the outer side of this end to prevent axial movement of the screw 61. Both the first anti-rotation baffle 63 and the second anti-rotation baffle 64 are secured to the inspection plate 5 via fastening screws 67.

[0030] The other end of the screw 61 passes through the third supporting surface 25 and the baffle 3 , and a manual nut 66 is installed on the end. The manual nut 66 adopts a through-hole structure and is located outside the baffle 3 to adjust the length of the screw 61 .

[0031] The compression spring 62 is assembled between the detection plate 5 and the third supporting surface 25 .

[0032] The detection system 7 mainly includes an electrical component 73 and a screw 71 of the test piece. The upper part of the detection plate 5, that is, the side away from and parallel to the fourth support surface 26, is used to fix the electrical component 73; it is feasible that the electrical component 73 is a proximity switch or a travel switch. The screw 71 of the test piece is fixed to the fixed plate 4 by two nuts 72. The screw 71 of the test piece is set to a certain length inside the sliding plate 4. When the lower group of hooks 22 is reliably fixed to the lower support rod 12, the screw head of the screw 71 of the test piece is just in the detection range of the electrical component 73. On the contrary, if the lower group of hooks 22 is not reliably fixed to the lower support rod 12, the screw head of the screw 71 of the test piece is not in the detection range of the electrical component 73, the detection component 73 alarms, and the display shows that the console is not reliably fixed.

[0033] The fifth supporting surface 27 and the inner side of the baffle 3 are assembled with a wear-resistant part 9; further, the wear-resistant part 9 is provided with a certain chamfer and other guiding structures, which is beneficial to the assembly of the console quick hook device.

[0034] The present application provides a working bucket, the front fence and / or the rear fence of the working bucket are provided with an upper support rod 11 and a lower support rod 12 for cooperating with the quick-hook device of the operating platform described in the first embodiment.

[0035] The present application also provides an aerial work vehicle, comprising the above-mentioned working bucket and the control panel quick-hook device described in Example 1.

[0036] Example 2:

[0037] This embodiment provides a method for using a console quick hitch device, including: When securing the console quick-attachment device, the device is first clamped onto the upper support rod 11 and the lower support rod 12. The manual nut 66 is then rotated forward, shortening the screw rod 61. The baffle 3 deforms and compresses under pressure, and the two wear-resistant parts 9 completely secure the lower support rod 12. Further rotation of the manual nut 66 causes the compression spring 62 to begin compressing under the action of the detection plate 5. When the compression spring 62 is compressed to a certain degree, the electrical component 73 detects the end of the screw 71 of the test piece, and the alarm stops, indicating that the console quick-attachment device has been successfully attached. The compression of the compression spring 62 increases, and the tightening torque of the manual nut 66 increases, preventing the manual nut 66 from being overtightened and causing damage to the lower hook 22 or the fifth support surface 27.

[0038] When the console quick-hook device is disassembled, the manual nut 66 is rotated in the opposite direction, the screw 61 becomes longer, the baffle 3 and the compression spring 62 return to a free state, the detection plate 5 pops up, and the position of the electrical component 73 relative to the end of the screw 71 changes relative to each other. At this time, the electrical component 73 issues an alarm, indicating that the device is in an unfixed state. At this time, the lower support rod 12 is completely disengaged, and the console quick-hook device can be removed and the position can be changed.

[0039] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the simplified description of the present application, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second", etc. are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features.
