Description

Technical Field

[0001] This utility model relates to the field of aerial work platform chassis technology, specifically to a cantilever boom aerial work platform chassis structure. Background Technology

[0002] Articulated boom lifts are specialized equipment for lifting operations. Nowadays, the chassis structures of articulated boom lifts, especially 14-meter and 16-meter lifts, vary greatly, resulting in a wide variety of structural, electrical, and hydraulic components and complex structures, leading to higher production costs.

[0003] Secondly, current aerial work platform chassis are unstable when turning due to the weight of the boom, especially when rotating to one side of the chassis. Furthermore, in existing aerial work platform chassis, the battery is usually placed inside the chassis, which is inconvenient for maintenance.

[0004] To overcome the aforementioned technical problems, Chinese patent CN221070876U describes an adjustable counterweight scissor lift chassis structure. It specifies that a first counterweight support plate is installed at the upper end of the first base plate as a chassis reinforcing beam. By equipping it with a matching "concave" middle and rear counterweights, it not only strengthens the chassis but also limits the left and right movement of the counterweights. This patent does indeed solve the problem of chassis instability that may occur when the boom rotates in the prior art. However, certain technical problems still exist. When the boom rotates, if it rotates 90° to the front or rear of the chassis, instability still occurs, thus requiring further improvement.

[0005] Therefore, in order to solve the above-mentioned existing technical problems, effectively improve the stability of the chassis, facilitate battery maintenance, and be able to adapt to both 14-meter and 16-meter articulated booms, an articulated boom aerial work platform chassis structure is proposed. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a hinged boom aerial work platform chassis structure, which solves the problems that existing hinged boom aerial work platform chassis cannot meet the installation requirements of 14-meter and 16-meter hinged boom lifting platforms, as well as the poor chassis stability during boom rotation and the inconvenience of battery maintenance.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a boom lift chassis structure, including a chassis frame, a rotating base mounted on the upper surface of the chassis frame, and upper mounting plates symmetrically mounted on the upper surface of the chassis frame. A connecting frame is inserted into the left end of the chassis frame, and an extended mounting frame is inserted into the other end. The connecting frame and the extended mounting frame are fixed to the chassis frame by bolts. The extended mounting frame and the connecting frame extend outward, and a connecting bracket is mounted on the outer end face of the extended mounting frame. Second, the two ends of the connecting frame are connected to the rear wheel hub by bolts. A steering structure is installed on the connecting frame. An external battery box structure is installed on both the front and rear ends of the chassis frame. The external battery box structure includes a box body, connecting lugs, batteries, a box cover, a connecting plate, and a raised plate. A connecting plate is installed on the front side of the chassis frame. Raised plates are symmetrically installed on the right side of the connecting plate. The raised plates are connected to the connecting lugs by pins. A box body is installed on one side of the connecting lugs. A box cover is installed on the top of the box body. Multiple sets of batteries are installed inside the box body.

[0008] Furthermore, through the above technical solution, transverse connecting frames are symmetrically installed on the inner side of the chassis frame.

[0009] Furthermore, support rods are installed on the front and rear end faces of the chassis frame, and the support rods are in contact with the bottom of the box.

[0010] As a preferred technical solution, the steering structure includes a steering seat, an adjusting body, an outer cover, a pin, a telescopic cylinder, a front wheel hub, and a wheel hub connecting seat. The steering seat is movably mounted in a connecting frame through a pin. A wheel hub connecting seat is installed on the outer side of the steering seat. The front wheel hub is bolted to the outer side of the wheel hub connecting seat. An adjusting body is installed on one side of the steering seat through a pin. A pin is installed at one end of the adjusting body, and a telescopic cylinder is connected to the surface of the pin.

[0011] Furthermore, an outer cover is installed on the surface of the adjusting body, which covers the connection between the telescopic cylinder and the pin.

[0012] As a preferred technical solution, the end of the connecting frame is at the same horizontal plane as the outer surface of the box.

[0013] Furthermore, a fixing seat is installed on the surface of the chassis frame located on the right side of the connecting plate, and a fixing plate is installed on the right side of the box.

[0014] Compared with the prior art, this utility model provides a boom lift chassis structure with the following advantages:

[0015] This chassis, by extending the connecting frame and the outer mounting frame outwards a certain distance than usual, addresses the significant difference in wheel hub width between the 14-meter and 16-meter articulated boom aerial work platforms, despite their identical structure. Extending the connecting frame and the outer mounting frame allows for the creation of a single chassis structure suitable for both 14-meter and 16-meter articulated boom aerial work platforms, thus significantly reducing costs.

[0016] This chassis, via connecting plates, raised plates, connecting lugs, mounting bases, and mounting plates, allows for easy battery maintenance by simply rotating the casing outwards and then removing the cover. This method is quite convenient. (See also...) Figure 1 as well as Figure 6 As can be seen, the housing is located on the front and rear sides of the chassis, which can provide a counterweight to the chassis. When the crank arm rotates to one side of the chassis via the rotating base, the weight of the housing can play a stabilizing role for the chassis. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0025] Please see Figure 1-6 This utility model provides the following technical solution: a boom lift chassis structure, including a chassis frame 1, a rotating base 4 mounted on the upper surface of the chassis frame 1, and upper mounting plates 3 symmetrically mounted on the upper surface of the chassis frame 1. A connecting frame 7 is inserted into the left end of the chassis frame 1, and an extended mounting frame 2 is inserted into the other end. The connecting frame 7 and the extended mounting frame 2 are fixed to the chassis frame 1 by bolts. The extended mounting frame 2 and the connecting frame 7 extend outward, and a connecting frame 8 is mounted on the outer end face of the extended mounting frame 2. The end face of the connecting frame 8 is connected to the rear wheel hub 9 by bolts. A steering structure 6 is installed on the frame 7. An external battery box structure 5 is installed on both the front and rear ends of the chassis frame 1. The external battery box structure 5 includes a box body 501, a connecting lug plate 502, a battery 503, a box cover 504, a connecting plate 10, and a protruding plate 11. A connecting plate 10 is installed on the front side of the chassis frame 1. A protruding plate 11 is symmetrically installed on the right side of the connecting plate 10. The protruding plate 11 is connected to the connecting lug plate 502 by a pin. A box body 501 is installed on one side of the connecting lug plate 502. A box cover 504 is installed on the upper end of the box body 501. Multiple sets of batteries 503 are installed inside the box body 501.

[0026] In this implementation plan, the specific working principle is as follows: When maintaining the battery, simply pull the housing 501 to rotate, thereby removing the housing cover 504. This greatly facilitates the maintenance work of the maintenance personnel. Secondly, the battery 503 is installed on the front and rear sides of the chassis 1 through the housing 501, which increases the counterweight on the front and rear sides of the chassis 1. This improves the overall stability of the chassis 1 when the boom arm rotates through the rotating base 4. Furthermore, the length of the connecting frame 7 and the extended mounting frame 2 has been extended to meet the wheel hub width of the 16-meter boom lift, so that the chassis 1 can simultaneously adapt to two specifications of boom lift wheel hubs. This unifies the structural, electrical, and hydraulic components in the chassis 1, with only the tires being different, which can save most of the production costs and facilitate production and warehouse management.

[0027] Based on the above, in order to further improve the stability of chassis 1, please refer to the following: Figure 2 and Figure 3As can be seen, transverse connecting frames 13 are symmetrically installed on the inner side of the chassis frame 1.

[0028] To ensure the multi-box 501 provides adequate support, please refer to the following for details. Figure 2 and Figure 5 As can be seen, support rods 14 are also installed on the front and rear end faces of the chassis frame 1, and the support rods 14 are in contact with the bottom of the box 501.

[0029] Secondly, for details on the steering structure, please refer to [link / reference]. Figure 2 and Figure 4 As can be seen, the steering structure 6 includes a steering seat 601, an adjusting body 602, an outer cover 603, a pin 604, a telescopic cylinder 605, a front wheel hub 606, and a wheel hub connecting seat 607. The steering seat 601 is movably mounted in the connecting frame 7 via a pin. The wheel hub connecting seat 607 is mounted on the outer surface of the steering seat 601. The front wheel hub 606 is bolted to the outer side of the wheel hub connecting seat 607. The adjusting body 602 is mounted on one side of the steering seat 601 via a pin. The pin 604 is mounted on one end of the adjusting body 602. The telescopic cylinder 605 is connected to the surface of the pin 604. When steering, the telescopic cylinder 6025 drives the steering seat 601 to rotate, thereby driving the front wheel hub 606 to adjust the steering.

[0030] To prevent dust from falling at the connection between the telescopic cylinder 605 and the pin 604, please refer to [the relevant documentation]. Figure 4 As can be seen, an outer cover 603 is installed on the surface of the adjusting body 602, and the outer cover 603 covers the connection between the telescopic cylinder 605 and the pin 604.

[0031] For details on how to accommodate the wheel hubs of a 16-meter-high articulated boom lift, please refer to [link / reference needed]. Figure 1 and Figure 2 As can be seen, the end of the connecting bracket 7 is on the same horizontal plane as the outer surface of the housing 501, which provides enough space to install a wider wheel hub.

[0032] For details on securing housing 501, please refer to [link / reference needed]. Figure 6 As can be seen, a fixing seat 12 is installed on the surface of the chassis frame 1 located on the right side of the connecting plate 10, and a fixing plate 505 is installed on the right side of the housing 501. The fixing plate 505 can be fixed to the fixing seat 12 simply by using bolts.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
