Description

Technical Field

[0001] This utility model relates to the field of aerial work platform technology, and in particular to a lower arm mounting and fixing device for aerial work platforms. Background Technology

[0002] Traditional aerial work platform boom fixing devices generally suffer from design flaws: most manufacturers only fix the upper boom, while the lower boom, due to the presence of a balance bar underneath, makes it difficult for the fixing structure to bypass this component. This technological gap causes the lower boom to sway from side to side when the vehicle is traveling at high speeds due to the lack of effective restraint, directly threatening the overall vehicle stability.

[0003] The issue of lower boom swaying has led to numerous safety accidents. When the vehicle bumps or turns, the lower boom may violently impact the upper boom, causing deformation or even breakage of the boom structure. Such malfunctions not only damage the equipment but can also lead to catastrophic consequences such as vehicle rollover, seriously threatening the personal safety of the driver and operators. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a lower arm mounting and fixing device for aerial work platforms. By utilizing the cooperation of the fixing brackets and the plug-in components, the distance between the two fixing brackets can be precisely adjusted according to the actual size of the lower arm and the installation requirements. Furthermore, it can effectively prevent the fixing brackets from separating or loosening during use, ensuring that the lower arm is reliably fixed to the device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A lower boom mounting and fixing device for an aerial work platform includes two base plates. Two mounting bolts for mounting the base plates are symmetrically arranged at the upper end of the base plates. A fixing frame is slidably connected to the upper end of the base plates. The two fixing frames are symmetrically arranged, and a plug-in assembly is provided between the two fixing frames.

[0007] A support assembly is provided between the fixing frame and the base plate;

[0008] The upper end of the base plate is provided with a sliding groove, and a moving component for moving the fixing frame is provided inside the sliding groove.

[0009] Preferably, the plug-in assembly includes a plug-in plate disposed on the side wall of one of the fixing frames, and a plug-in slot for the plug-in plate to be adapted to the side wall of the other fixing frame.

[0010] Preferably, the support assembly includes two sliding plates symmetrically arranged on the side wall of the fixed frame, the sliding plates being slidably connected to the base plate, and a reinforcing plate being fixedly installed between the sliding plates and the fixed frame.

[0011] Preferably, the reinforcing plate is a hollow structure.

[0012] Preferably, the moving component includes a screw rotatably connected inside the slide groove, a threaded slider threadedly connected to the screw, the threaded slider being fixedly connected to a fixed frame, and a handwheel rotatably connected to the side wall of the fixed frame, the handwheel being coaxially fixed with the screw.

[0013] Preferably, rubber pads are fixedly installed on opposite sides of both of the fixing brackets.

[0014] This utility model has the following beneficial effects:

[0015] The two mounting brackets are connected by a plug-in assembly. The plug-in plate fits into the plug-in slot, and when the lower arm is placed between the two mounting brackets and the plug-in plate is inserted into the plug-in slot, a stable connection structure is formed. This plug-in method can effectively prevent the mounting brackets from separating or loosening during use, ensuring that the lower arm is reliably fixed to the device.

[0016] The fixed frame and the base plate are connected by a support assembly. Two sliding plates, symmetrically arranged on the side wall of the fixed frame, are slidably connected to the base plate. At the same time, a reinforcing plate is fixedly installed between the sliding plates and the fixed frame. This multi-point support and reinforcement design increases the connection strength and stability between the fixed frame and the base plate, enabling the entire device to maintain structural stability and prevent deformation or damage when subjected to the weight of the lower arm and external forces.

[0017] The position of the mounting brackets can be precisely adjusted by moving the components. Turning the handwheel rotates the screw, which in turn moves the threaded slider on the screw, thus moving the mounting brackets. The operator can precisely adjust the distance between the two mounting brackets according to the actual size of the lower arm and the installation requirements, making the device adaptable to lower arms of different specifications and improving its versatility and applicability.

[0024] Some exemplary embodiments of the present invention have been described for illustrative purposes. It should be understood that the present invention may be implemented in other ways not specifically shown in the accompanying drawings.

[0025] Reference Figures 1-3 A lower boom mounting and fixing device for an aerial work platform includes two base plates 1. Two mounting bolts 3 for mounting the base plates 1 are symmetrically arranged on the upper end of the base plates 1. A fixing frame 7 is slidably connected to the upper end of the base plates 1. The two fixing frames 7 are symmetrically arranged. A rubber pad is fixedly installed on the opposite side of each of the two fixing frames 7. The surface of the rubber pad is provided with anti-slip texture to increase the friction when in contact with the lower boom. The rubber pad is also embedded with a metal mesh skeleton to improve its tear resistance.

[0026] A plug-in assembly is provided between the two fixed frames 7. The plug-in assembly includes a plug-in plate 8 provided on the side wall of one of the fixed frames 7, and a plug-in groove 10 for the plug-in plate 8 to be adapted to the side wall of the other fixed frame 7. The end of the plug-in plate 8 is provided with a chamfer structure to facilitate quick insertion into the plug-in groove 10.

[0027] A support assembly is provided between the fixed frame 7 and the base plate 1. The support assembly includes two slide plates 9 symmetrically arranged on the side wall of the fixed frame 7. The slide plates 9 are slidably connected to the base plate 1. A reinforcing plate 6 is fixedly installed between the slide plates 9 and the fixed frame 7. The reinforcing plate 6 is a hollow structure.

[0028] The upper end of the base plate 1 is provided with a slide groove 4. The slide groove 4 is provided with a moving component for moving the fixed frame 7. The moving component includes a screw 5 rotatably connected inside the slide groove 4. A threaded slider 11 is threadedly connected to the screw 5. The threaded slider 11 is fixedly connected to the fixed frame 7. A handwheel 2 is rotatably connected to the side wall of the fixed frame 7. The handwheel 2 is coaxially fixed with the screw 5.

[0029] Working principle:

[0030] Install the base plate 1 into the appropriate position using mounting bolts 3. Then, turn the handwheel 2, which drives the screw 5 to rotate within the groove 4. As the screw 5 rotates, the threaded slider 11 moves along the screw 5, thereby moving the fixing frame 7. Simultaneously, the slide plate 9 slides on the base plate 1, providing guidance and support for the movement of the fixing frame 7. The reinforcing plate 6 enhances the connection strength between the slide plate 9 and the fixing frame 7.

[0031] Place the lower arm of the aerial work platform between the two fixed frames 7, and continue to turn the handwheel 2 to adjust the position of the fixed frames 7 so that the insertion plate 8 on the side wall of one fixed frame 7 is inserted into the insertion slot 10 on the side wall of the other fixed frame 7, thus connecting and fixing the two fixed frames 7. At this time, the rubber pad on the opposite side of the fixed frame 7 contacts the lower arm, which plays a role in buffering and protection, preventing damage to the lower arm, and thus completing the placement and fixing of the lower arm.
