Description

Technical Field

[0001] This utility model mainly relates to the field of tracked chassis technology, specifically to a terrain-adaptive tracked platform. Background Technology

[0002] Conventional aerial work platforms using wheeled chassis have poor mobility in complex terrain. While replacing them with tracked chassis improves mobility, the tracked chassis and the entire equipment may tilt when retracted to terrain limitations during subsequent lifting operations, making it impossible to guarantee the stable lifting of the aerial work platform.

[0003] The inventors proposed a terrain-adaptive tracked platform. By adopting a tracked chassis design, the equipment's obstacle-crossing ability is improved. A deflectable component is set between the chassis and the scissor lift to enable the equipment to be deployed in complex terrain conditions and to ensure the level of the aerial work platform, making it convenient for users to carry out aerial work in complex terrain conditions.

[0017] See attached document Figure 1-5 This utility model provides a terrain-adaptive tracked platform, including a frame 1, a spacer frame 2 fixedly mounted on the top of the frame 1, a bracket 5 fixedly mounted on the top of the spacer frame 2, a mounting frame 6 that can be tilted on the top of the bracket 5, and a scissor lift 7 mounted on the top of the mounting frame 6.

[0018] In this embodiment, tracked walking components 4 are fixed on both the left and right sides of the vehicle frame 1.

[0019] The chassis 1 is equipped with a tracked walking assembly 4, which provides better passability and obstacle crossing ability compared to traditional wheeled chassis when sending the scissor lift 7 into the designated working area.

[0020] In this embodiment, deflection hydraulic cylinders 21 are movably connected to the top four corners of the spacer frame 2, and mounting bases 3 are detachably connected to the four corners of the spacer frame 2. The middle and top of the mounting base 3 are movably connected to the main arm 31 and the first hydraulic cylinder 32, respectively. The output end of the first hydraulic cylinder 32 is movably connected to the top of the main arm 31. The top and bottom of the main arm 31 are movably connected to the connecting base 33 and the second hydraulic cylinder 34, respectively. The top of the second hydraulic cylinder 34 is movably connected to the bottom of the connecting base 33. The bottom of the connecting base 33 is fixedly provided with a forearm 35, and the bottom of the forearm 35 is movably connected to a base support 36. The forearm 35 is composed of a telescopic rod assembly with locking.

[0021] The first hydraulic cylinder 32 outside the mounting base 3 completes the deployment and retraction of the boom 31. The second hydraulic cylinder 34 cooperates with the connecting base 33 to complete the deployment and retraction of the forearm 35 outside the boom 31. Before the scissor lift 7 is lifted, the boom 31 and forearm 35 need to be deployed. After the base 36 touches the bottom, the stability of the equipment is increased in conjunction with the track walking assembly 4.

[0022] In this embodiment, the front and rear ends of the bracket 5 are fixedly provided with a fixed frame 51. The bottom of the fixed frame 51 is movably connected with a connecting shaft 52. The middle of the fixed frame 51 is provided with a guide hole 53. The bottom of the front and rear ends of the mounting frame 6 are fixedly provided with a deflection frame 61. The bottom of the two deflection frames 61 is movably connected to the outer side of the two connecting shafts 52 respectively. The middle of the deflection frame 61 is fixedly provided with a guide pin 62. The end of the guide pin 62 extends into the guide hole 53. The top left and right sides of the deflection frame 61 are movably connected to the output ends of two deflection hydraulic cylinders 21 respectively. The connection point between the deflection hydraulic cylinder 21 and the deflection frame 61 is higher than the center position of the connecting shaft 52. The outside of the mounting frame 6 and the working platform of the scissor lift 7 are both fixedly provided with tilt sensors. The tilt sensors are electrically connected to a PLC control module. The PLC control module is electrically connected to a solenoid valve. The solenoid valve cooperates with the deflection hydraulic cylinder 21.

[0023] The deflection hydraulic cylinders 21 located at the four corners of the spacer extend and retract according to the tilt of the equipment in the actual terrain. The two groups of deflection hydraulic cylinders 21 located on the left and right sides of the spacer begin to extend and retract, completing the deflection of the deflection frame 61 with the connecting shaft 52 as the center on the outside of the fixed frame 51, adjusting the working platform of the scissor lift 7 to be level. The specific level is determined by the tilt sensor, PLC control module and solenoid valve to adjust the action of the deflection hydraulic cylinders 21.

[0024] Detailed operating procedures: When the equipment is deployed in complex terrain, the boom 31 and boom 35 need to be deployed. After the base 36 touches the ground, the stability of the equipment deployment in complex terrain is improved in conjunction with the tracked walking assembly 4. Two sets of deflection hydraulic cylinders 21 located on the left and right sides of the spacer begin to extend and retract, completing the deflection frame 61 deflecting around the connecting shaft 52 on the outside of the fixed frame 51, adjusting the working platform of the scissor lift 7 to a horizontal position, allowing users to carry out high-altitude operations in complex terrain conditions. Combined with the obstacle-clearing capability of the tracked walking assembly 4, the equipment movement route and terrain leveling work in the construction area are eliminated, reducing the construction difficulty and cost for users in complex terrain conditions.
