Description

Technical Field

[0001] This utility model relates to the field of aerial work platform technology, specifically to an anti-tilt chassis. Based on this, it also relates to an aerial work platform. Background Technology

[0002] An aerial work platform is a specialized piece of machinery equipped with a lifting basket that can raise personnel and equipment to a height for work. Aerial work platforms can be categorized by their mobility method: self-propelled aerial work platforms, mobile aerial work platforms, towed aerial work platforms, and vehicle-mounted aerial work platforms.

[0003] Existing aerial work platforms generally consist of a chassis and a working mechanism mounted on the chassis. When the aerial work platform moves to an uneven road surface or slope, the chassis tilts, which can easily cause the aerial work platform to overturn. Utility Model Content

[0004] The purpose of this invention is to provide an anti-tipping chassis that allows for adaptive adjustment of the chassis tilt angle, thereby reducing the risk of overturning of aerial work platforms.

[0005] To achieve the above objectives, this utility model provides an anti-roll chassis, comprising: a frame, an axle hinged to the end of the frame via a pin, and an anti-roll mechanism. The pin is arranged at the end of the frame parallel to the extension direction of the frame, and the axis of the pin coincides with the center line of the frame. The anti-roll mechanism is connected to the frame and the axle respectively. The anti-roll mechanism includes a leveling rod for connecting to the frame, rocker arms respectively disposed on both sides of the frame and connected to the ends of the leveling rod, and a connecting rod assembly. The two ends of the connecting rod assembly are respectively connected to the rocker arms and the axle. The connecting rod assembly is configured to apply opposite torques to the two ends of the leveling rod via the rocker arms when the frame tilts.

[0006] In some embodiments, the leveling rod includes an elastic rod connected to the frame, with the rocker arm connected to each end of the elastic rod.

[0007] In some embodiments, the anti-roll mechanism further includes a bushing for fitting onto the leveling bar, the bushing being mounted in a bushing support of the frame.

[0008] In some embodiments, the anti-roll mechanism further includes a stop disc for mounting on the leveling bar, the stop disc being fixedly connected to the leveling bar and mounted on the side of the bushing away from the frame.

[0009] In some embodiments, the leveling rod extends through both sides of the frame, the bushing support is disposed on the side wall of the frame, the bushing is sleeved on the leveling rod and installed in the bushing support, and the stop plate is sleeved on the leveling rod and installed on the side of the bushing away from the frame.

[0010] In some embodiments, the connecting rod assembly includes a connecting rod and connector components respectively disposed at both ends of the connecting rod, the connecting rod being connected to the rocker arm and the axle respectively through the connector components.

[0011] In some embodiments, the connector component includes ball joints disposed at both ends of the connecting rod, and the connecting rod is connected to the rocker arm and the axle respectively through the ball joints.

[0012] In some embodiments, the length of the connecting rod is adjustable.

[0013] In some embodiments, the anti-roll chassis further includes floating cylinders, which are disposed opposite to the anti-roll mechanism at both ends of the vehicle frame. The axle includes a front axle and a rear axle respectively hinged to both ends of the vehicle frame. The floating cylinders are respectively disposed on both sides of the vehicle frame, with one end connected to the vehicle frame and the other end connected to one of the front axle and the rear axle. The other end of the connecting rod assembly is connected to the other of the front axle and the rear axle.

[0014] In some embodiments, the anti-roll chassis further includes steering knuckles respectively hinged to the ends of the axle, a travel reduction gear mounted on the steering knuckles, and tires drivenly connected to the travel reduction gear.

[0015] Based on this, the present invention also provides an aerial work platform, including a working mechanism for mounting the platform and the aforementioned anti-tilt chassis, wherein the working mechanism for mounting the platform is mounted on the anti-tilt chassis.

[0016] Through the above technical solution, the axles are hinged to the frame, for example, the front axle and the rear axle are hinged to the frame respectively. The front axle and the rear axle can swing relative to the frame. When the front axle and / or the rear axle travel on uneven roads, the swinging of the front axle and / or the rear axle relative to the frame improves the road adaptability of the anti-roll chassis of this utility model. The pin is arranged at the end of the frame parallel to the extension direction of the frame, and the axis of the pin coincides with the center line of the frame, so as to facilitate the swinging of the axle relative to the frame. Furthermore, in the driving state, the front axle and the rear axle of the anti-roll chassis can swing independently. In the case of rough road conditions, the front and rear axles can produce opposite swing angles, and the relative swing angle between the front and rear axles is larger, which can easily cope with the cross-axle driving situation, thereby improving the passability and off-road performance of the anti-roll chassis.

[0017] Additionally, an anti-roll mechanism is installed between the axle and the frame. This anti-roll structure includes a leveling rod, rocker arms, and a connecting rod assembly connected to the frame. The rocker arms are connected to the leveling rod at both ends and are respectively positioned on both sides of the frame. The connecting rod assembly is connected to the rocker arms and the axle at both ends. When the frame tilts, for example, when the anti-roll chassis travels over uneven roads, the axle deflects, and the frame tilts under gravity—that is, one side of the frame tilts closer to the axle and the other side tilts away from the axle—the anti-roll mechanism, connected to the leveling rod, balances the axle. The end of the rod is connected to a rocker arm. When one side of the chassis tilts towards the axle, a force towards the axle is applied to the end of the rocker arm connected to the leveling rod. The other end of the rocker arm is connected to a connecting rod assembly, which in turn is connected to the axle. Thus, the other end of the rocker arm generates a torque that brings the chassis closer to the axle. This torque is transmitted along the leveling rod to the other end of the leveling rod and acts on the other side of the chassis, causing the other side of the chassis, which originally tended to tilt away from the axle, to tilt towards the axle. In other words, this torque is opposite to the tilting direction of the other side of the chassis. Conversely, when the other side of the chassis tilts away from the axle, the other end of the rocker arm on that side generates a torque that moves the chassis away from the axle. This torque is transmitted to one side of the chassis and is opposite to the tilting direction of that side, thereby reducing the tilt angle of the chassis and facilitating adaptive leveling during chassis operation.

[0030] An aerial work platform is a specialized piece of machinery equipped with a lifting basket that can raise personnel and equipment to a height for work. Aerial work platforms can be categorized by their mobility: self-propelled aerial work platforms, mobile aerial work platforms, towed aerial work platforms, and vehicle-mounted aerial work platforms. Self-propelled aerial work platforms primarily utilize two chassis types for drive: wheeled and tracked. Existing wheeled self-propelled aerial work platforms generally employ a dedicated heavy-duty chassis as the load-bearing device for the upper working mechanism. This chassis typically includes a frame, front axle, rear axle, and wheels.

[0031] Currently, self-propelled aerial work platforms mainly adopt integrated chassis and front-axle floating chassis. The integrated chassis has a frame, front axle, and rear axle as a single unit, meaning the tires connected to the frame can only move in a single plane and lack vertical movement. Therefore, integrated chassis are generally suitable for indoor and flat road operations, but have poor off-road performance and weak traction. When traversing uneven terrain, there is a safety hazard of the aerial work platform tipping over. The front-axle floating chassis has a frame and front axle hinged together by a pin, allowing the front axle to swing around the frame within a certain angle range, providing some off-road performance. However, the frame and rear axle are still a single unit, and traction is limited only by the front axle. This limits the chassis's traction in harsh road conditions. Furthermore, because the frame and rear axle are integrated, the tilt of the upper working mechanism changes synchronously with the rear axle, resulting in weak anti-roll capability when traversing unpaved roads. Additionally, the chassis tilt angle cannot be adjusted, limiting its ability to operate on slopes.

[0032] This utility model addresses the technical problems of poor off-road performance and weak anti-roll capability of existing self-propelled aerial work platform chassis by providing an anti-roll chassis, with reference to... Figures 1-3As shown, according to one embodiment of the anti-roll chassis of this utility model, the anti-roll chassis includes: a frame 10, an axle, and an anti-roll mechanism. The axle is hinged to both ends of the frame 10 via pins, allowing the axle to swing relative to the frame 10 within a certain angle range. The anti-roll mechanism is connected to both the frame 10 and the axle. The pins are arranged parallel to the extension direction of the frame 10 at the ends of the frame 10, and the axis of the pins coincides with the center line of the frame 10. The anti-roll mechanism includes a leveling rod for connecting to the frame 10, rocker arms 12 respectively disposed on both sides of the frame 10 and connected to the ends of the leveling rod, and a connecting rod assembly. The two ends of the connecting rod assembly are connected to the rocker arms 12 and the axle, respectively. The connecting rod assembly is configured such that when the frame 10 tilts, the rocker arms 12 apply torques in opposite directions to the two ends of the leveling rod.

[0033] In the anti-roll chassis provided by this utility model, the axles are hinged to both ends of the frame 10 via pins. This allows the axles to swing relative to the frame 10 within a certain angle range. When the chassis travels on uneven roads, the swinging of the axles relative to the frame 10 improves the road adaptability of the anti-roll chassis. The pins are arranged parallel to the extension direction of the frame 10 at the ends of the frame 10, with the pin axis coinciding with the center line of the frame 10, i.e., the pin is located in the middle of the ends of the frame 10. The axles are hinged to the ends of the frame 10 via the pins, which facilitates the swinging of the axles relative to the frame 10. Moreover, when the anti-roll chassis is in motion, the axles at both ends of the frame 10, such as the front and rear axles, swing independently. In harsh road conditions, the front and rear axles can produce opposite swing angles, resulting in a larger relative swing angle between the front and rear axles. This allows for more confident handling of cross-axle driving situations, thereby improving the passability and off-road performance of the anti-roll chassis.

[0034] In addition, an anti-roll mechanism is provided between the axle and the frame 10. The anti-roll structure includes a leveling rod, a rocker arm 12, and a connecting rod assembly connected to the frame 10. The rocker arm 12 is connected to both ends of the leveling rod and is respectively located on both sides of the frame 10. The two ends of the connecting rod assembly are respectively connected to the rocker arm 12 and the axle. When the anti-roll chassis is driving on a flat road, under the combined action of the axle, the pin, and the anti-roll mechanism, it provides sufficient support to the frame 10, so that the angle of the anti-roll chassis relative to the ground remains basically unchanged. When the anti-roll chassis travels over uneven roads, the axle deflects, and the frame 10 tilts under the influence of gravity. That is, one side of the frame 10 tilts closer to the axle, and the other side tilts away from the axle. Since the frame 10 is connected to the leveling rod, and the end of the leveling rod is connected to the rocker arm 12, when one side of the frame 10 tilts towards the axle, a force is applied towards the axle to the end of the rocker arm 12 connected to the leveling rod. The other end of the rocker arm is connected to a connecting rod assembly, which is also connected to the axle. Thus, the other end of the rocker arm 12 generates a torque that brings the frame 10 closer to the axle. This torque is transmitted along one end of the leveling rod to the other end of the leveling rod and acts on the other side of the frame 10, causing the other side of the frame 10, which originally had a tendency to tilt away from the axle, to tilt towards the axle. That is, the torque is opposite to the tilting direction of the other side of the frame 10. Correspondingly, when the other side of the frame 10 tilts away from the axle, the other end of the rocker arm 12 on that side will generate a torque that moves the frame 10 away from the axle. This torque is transmitted to one side of the frame 10 and is opposite to the tilt direction of one side of the frame 10, thereby reducing the tilt angle of the frame 10 and helping to achieve the adaptive leveling function of the anti-roll chassis during driving.

[0035] According to one embodiment of the anti-rollover chassis of this utility model, refer to Figures 1-3 As shown, the leveling rod includes an elastic rod 15 connected to the frame 10, with rocker arms 12 connected to both ends of the elastic rod 15. The elastic rod 15 is elastic; when its two ends are subjected to opposite torques, it undergoes elastic deformation and torsion. This torsional torque, transmitted from one end of the elastic rod 15 to the other, generates a torque on the frame 10 located at the other end of the elastic rod 15 in the opposite direction of its tilt, thereby reducing the tilt angle of the frame 10 and achieving adaptive leveling during the anti-roll chassis operation. Furthermore, compared to a rigid rod, the elasticity of the elastic rod 15 extends its service life under torsional operating conditions.

[0036] Alternatively, the elastic rod 15 may be a torsion spring rod.

[0037] According to one embodiment of the anti-rollover chassis of this utility model, refer to Figure 1 and Figure 2 As shown, the elastic rod 15 is connected to the rocker arm 12 in a transmission manner, allowing the rocker arm 12 to transmit torque to the elastic rod 15. Furthermore, in conjunction with... Figure 2As shown, a spline is formed on the outer peripheral surface of the end of the elastic rod 15. The elastic rod 15 and the rocker arm 12 are connected by a spline engagement, which facilitates the installation and disassembly of the elastic rod 15 and the rocker arm 12, and is beneficial to the maintenance of the anti-tilting mechanism. Of course, in this utility model, the elastic rod 15 and the rocker arm 12 are not limited to a spline engagement connection. For example, a shear pin can be provided between the elastic rod 15 and the rocker arm 12 to achieve a transmission connection, or the elastic rod 15 and the rocker arm can also be connected by a profile to achieve torque transmission.

[0038] In another embodiment of the anti-rollover chassis of this utility model, the elastic rod 15 and the rocker arm 12 can be an integral structure. For example, the elastic rod 15 and the rocker arm 12 form an integral elastic irregular connecting rod structure, which is connected to the frame 10 and the connecting rod assembly respectively.

[0039] According to one embodiment of the anti-rollover chassis of this utility model, refer to Figure 2 As shown, the anti-tilt mechanism of this utility model also includes a bushing 14 for sleeved on the leveling rod, and the bushing 14 is installed in the bushing support 16 of the frame 10. In this way, the bushing 14 is installed in the bushing support 16, and the leveling rod is rotatably connected to the bushing 14, so that the bushing 14 can restrict the movement of the leveling rod in a radial direction parallel to the bushing 14, which is beneficial to maintaining the stability of the leveling rod.

[0040] Furthermore, the bushing 14 is a rubber bushing, which has a certain elasticity. When the elastic rod 15 is subjected to torque, there is a certain friction between the elastic rod 15 and the rubber bushing. In this way, the rubber bushing can absorb and suppress the energy generated by the deformation and torsion of the elastic rod 15, thereby improving the comfort and safety of the anti-roll chassis of this utility model during driving.

[0041] Furthermore, referring to Figure 2 As shown, the anti-tilt mechanism of this utility model also includes a stop plate 13 for being sleeved on the leveling rod. The stop plate 13 is fixedly connected to the leveling rod and installed on the side of the bushing 14 away from the frame 10. In this way, the stop plates 13 on both sides of the frame 10 can restrict the movement of the leveling rod in its axial direction, which is beneficial to maintaining the stability of the leveling rod.

[0042] Optionally, the stop plate 13 is threadedly connected to the leveling rod, thereby fixing the stop plate 13 to the leveling rod and restricting the movement of the leveling rod along its axial direction. Of course, the stop plate 13 can also be fixed to the leveling rod by means of bonding, keying, or other methods.

[0043] Furthermore, an installation notch is formed on the outer peripheral surface of the stop plate 13 to facilitate the installation tool to clamp the stop plate 13 and install the stop plate 13 onto the leveling rod.

[0044] According to one embodiment of the anti-rollover chassis of this utility model, see [link to relevant documentation]. Figures 1-3 As shown, the leveling rod is provided through both sides of the frame 10, the bushing support 16 is provided on the side wall of the frame 10, the bushing 14 is sleeved on the leveling rod and installed in the bushing support 16, and the stop plate 13 is sleeved on the leveling rod and installed on the side of the bushing 14 away from the frame 10.

[0045] According to other embodiments of the anti-rollover chassis of this utility model, the bushing support 16 is not set on the two side walls of the frame 10. The bushing support 16 can be set above, below, in front of or behind the frame 10. Any similar installation arrangement is within the protection scope of this utility model.

[0046] Reference Figures 1-3 As shown, in one embodiment of the anti-roll chassis provided by this utility model, the connecting rod assembly includes a connecting rod 11 and joint components respectively disposed at both ends of the connecting rod 11. The connecting rod 11 is connected to the rocker arm 12 and the axle respectively through the joint components. Specifically, the two ends of the connecting rod 11 are respectively connected to joint components, one of which is connected to the end of the rocker arm 12 away from the leveling rod, and the other joint component is connected to the axle.

[0047] According to one embodiment of the present invention, combined with Figure 2 As shown, the joint component includes ball joints at both ends of the connecting rod 11, which connects the connecting rod 11 to the rocker arm 12 and the axle respectively. Since the ball joints have multiple degrees of freedom, additional bending moments can be avoided when the connecting rod 11 applies torque to the rocker arm 12 through the ball joints. Simultaneously, the ball joints partially restrict the movement of the connecting rod 11 during the axle's swing motion.

[0048] Optionally, the length of the connecting rod 11 can be a fixed length.

[0049] Alternatively, according to a preferred embodiment of the anti-roll chassis of this utility model, the length of the connecting rod 11 is adjustable. Thus, the length of the connecting rod 11 can be adjusted according to the installation state between various structures and components of the anti-roll chassis, such as the frame 10, rocker arm 12, and axle, thereby compensating for errors caused by structural manufacturing and assembly. Of course, there are various structures that enable the length of the connecting rod 11 to be adjustable, including but not limited to the connecting rod 11 being a telescopic rod, or the connecting rod 11 being threadedly connected to the joint component, and the length of the connecting rod between the two joint components being adjusted by relative rotation of the connecting rod and the joint component.

[0050] Furthermore, referring to Figure 1 and Figure 2As shown, the anti-roll chassis of this utility model also includes a floating cylinder 6. The floating cylinder 6 is disposed opposite to the anti-roll mechanism at both ends of the frame 10. The axle includes a front axle 8 and a rear axle 17 respectively hinged to both ends of the frame 10. The floating cylinder 6 is disposed on both sides of the frame 10 and one end is connected to the frame 10, and the other end is connected to one of the front axle 8 and the rear axle 17. The other end of the connecting rod assembly is connected to the other of the front axle 8 and the rear axle 17.

[0051] Specifically, see Figure 2 As shown, the pins include a front axle pin 9 and a rear axle pin 18. The front axle pin 9 and the rear axle pin 18 are respectively arranged at both ends of the frame 10 along the extension direction parallel to the frame 10. The axes of the front axle pin 9 and the rear axle pin 18 coincide with the center line of the frame 10, that is, the front axle pin 9 and the rear axle pin 18 are respectively located at the middle position of the end of the frame 10 to facilitate the swing of the front axle 8 and the rear axle 17. The front axle 8 is hinged to the front end of the frame 10 through the front axle pin 9, and the rear axle 17 is hinged to the rear end of the frame 10 through the rear axle pin 18. The floating cylinder 6 can be set at the front or rear of the frame 10, and the anti-roll mechanism can be set at the rear or front of the frame 10 accordingly. For example, the floating cylinder 6 is set at the front of the frame 10, and the anti-roll mechanism is set at the rear of the frame 10. Specifically, one end of each of the two floating cylinders 6 is hinged to the front sides of the frame 10 via a first cylinder pin 5, and the other end of each of the two floating cylinders 6 is hinged to the front axle 8 via a second cylinder pin 7. The leveling rod of the anti-roll mechanism is connected to the rear of the frame 10, and the two rocker arms 12 of the anti-roll mechanism are located on both sides of the frame 10 and connected to the two ends of the leveling rod, respectively. The rocker arms 12 are connected to the rear axle 17 via a connecting rod assembly. Of course, the floating cylinders 6 can also be located at the rear of the frame 10, and the anti-roll mechanism can be located at the front of the frame 10, which will not be elaborated here.

[0052] Floating cylinders 6 are installed on both sides of the chassis 10. When the anti-roll chassis is in motion, the floating cylinders 6 are in a free state, meaning they extend or compress freely with the movement of the axle without restricting its movement. When the anti-roll chassis is in operation, the floating cylinders 6 are engaged. By controlling the extension or compression of the floating cylinders 6, support force is provided to the chassis 10, and the tilt angle of the chassis 10 is adjusted. Since the axle and chassis 10 are hinged, the axle can swing relative to the chassis 10. Therefore, the floating cylinders 6 can adjust the tilt angle of the chassis 10 within the swing angle range of the axle. When the tilt angle of the chassis 10 reaches a predetermined angle, for example, after the chassis 10 is leveled, the floating cylinders 6 are locked to maintain the stability of the chassis 10. Thus, when the anti-roll chassis is operating on a slope, the tilt angle of the chassis 10 can be adjusted by the floating cylinders 6, reducing the overturning moment caused by the shift in the center of gravity when the chassis 10 tilts, thereby improving operating performance and overall machine stability.

[0053] Therefore, in the anti-roll chassis provided by this utility model, during driving, the anti-roll mechanism can apply a torque opposite to the tilt direction of the frame 10 according to the tilt of the frame 10, thereby achieving adaptive leveling of the frame 10. When the anti-roll chassis is in operation, the tilt angle of the frame 10 is adjusted by a floating hydraulic cylinder to ensure that the frame 10 operates in a leveled state. Of course, during the process of the floating hydraulic cylinder 6 adjusting the tilt angle of the frame 10, the anti-roll mechanism will also level the tilt angle of the frame 10, further realizing the leveling function of the frame 10 during operation.

[0054] In addition, see Figure 1 and Figure 2 As shown, according to one embodiment of the anti-roll chassis of this utility model, the anti-roll chassis further includes a steering knuckle 3 hinged to the end of the axle, a travel reducer 2 mounted on the steering knuckle 3, and a tire 1 that is pulsatorically connected to the travel reducer 2. The steering knuckle 3 is hinged to the end of the axle via a steering pin 4, so that the steering knuckle can rotate relative to the axle around the steering pin 4, thereby changing the travel direction of the anti-roll chassis during operation.

[0055] Based on this, the present invention also provides an aerial work platform, which includes an upper working mechanism and the aforementioned anti-tilt chassis, with the upper working mechanism installed on the anti-tilt chassis.

[0056] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings; however, this utility model is not limited thereto. Within the scope of the technical concept of this utility model, various simple modifications can be made to the technical solution of this utility model, including the combination of various specific technical features in any suitable manner. To avoid unnecessary repetition, this utility model will not describe the various possible combinations separately. However, these simple modifications and combinations should also be considered as the content disclosed by this utility model and all fall within the protection scope of this utility model.
