Problems solved by technology

However, in actual use, the disadvantage of the above-mentioned spring return mechanism is that after the working device crosses obstacles, it will produce elastic oscillation or harmful impact, and form a working blind area, thus greatly reducing the working quality of the road maintenance machinery and the reliability of its own structure

Embodiment 1

[0040] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 8 and Figure 9 As shown, the present invention includes an installation base 13 and a rotating obstacle-surmounting device arranged on the installation base 13 and capable of automatically driving the working device of the road maintenance machinery to rotate and overcome obstacles. The installation base 13 is vertically fixedly installed on the The working device substrate 1 for the stable installation of the working device is coaxially sleeved on the rotating main shaft 11 that drives the working device, and the power shaft 5 that drives it is arranged directly above the rotating main shaft 11 and The rotating main shaft 11 is coaxially connected with the power shaft 5, and the rotating main shaft 11 and the power shaft 5 form a driving shaft for driving the working device. The rotary obstacle clearance device includes a plurality of positioning pressure beads 10, an annular revolving raceway 4 provid...

Embodiment 2

[0050] combine Figure 5 , In this embodiment, the difference from Embodiment 1 is that the number of the positioning pressure beads 10, the positioning slots 12 and the rotation pushing units are the same and are all 3 and N=3, and the clutch slip ring 7 , the installation base 13, the friction cone ring 8 and a plurality of said rotating push units constitute the clutch slip ring 7 and the friction cone ring 8 in direct contact with the friction state to perform a 120° rotation on the working device substrate 1 to overcome obstacles device. After crossing the fixed obstacle (i.e. the base plate 1 of the working device rotates 120°), the three positioning pressure beads 10 roll respectively along the same circumferential direction to the next positioning slot 12 arranged on the revolving raceway 4. Each positioning pressure ball 10 pushes up the three push rods 9 respectively, so that the clutch slip ring 7 and the friction cone surface ring 8 are separated under the pushing...

Embodiment 3

[0052] combine Image 6 , in this embodiment, the difference from Embodiment 1 is that the number of the positioning pressure beads 10, the positioning slots 12 and the rotation pushing units are the same and are all 4 and N=4, and the clutch slip ring 7 , the installation base 13, the friction cone ring 8 and a plurality of said rotating push units constitute the clutch slip ring 7 and the friction cone ring 8 in direct contact with the friction state to perform a 90° rotation on the working device substrate 1 to overcome obstacles device. After crossing the fixed obstacle (i.e. the working device base plate 1 is rotated by 90°), the four positioning pressure beads 10 roll respectively along the same circumferential direction to the next positioning slot 12 arranged on the revolving raceway 4. At this time, the four Each positioning pressure ball 10 pushes up the four push rods 9 respectively, so that the clutch slip ring 7 and the friction cone surface ring 8 are separated ...

Abstract

The invention discloses an automatic power-assisted rotary obstacle crossing mechanism, which comprises a mounting base and a rotary obstacle crossing device capable of automatically driving a working device of a road maintenance machine to rotate and cross an obstacle, wherein the mounting base is vertically and fixedly arranged on a working device base plate for stably mounting the working device, and the mounting base and the base plate are coaxially sleeved on a rotary main shaft for driving the working device; and the rotary obstacle crossing device comprises a plurality of positioning pressure balls, a circular rotary roller way formed in the mounting base and provided for the positioning pressure balls to roll along the circumferential direction, frictional conical surface rings coaxially and fixedly sleeved on a driving shaft, clutch slip rings capable of moving up and down along the driving shaft and moving downwards to directly contact with the frictional conical surface rings, and a plurality of rotary push units for pushing the clutch slip rings up and down. The mechanism has reasonable design, simple structure, convenience for use and operation and good use effect, does not need an additional power source, and can eliminate oscillating crash produced when the conventional spring reset mechanism crosses the obstacle and a working blind area.

Description

technical field [0001] The invention relates to an automatic obstacle-climbing device for large-scale mechanical equipment, in particular to an automatic power-assisted rotating obstacle-climbing mechanism. Background technique [0002] At present, during the actual use of road maintenance machinery, the main movement of the working devices installed on the road maintenance machinery is mostly rotary motion. Nowadays, when the road maintenance machinery needs to avoid or bypass fixed obstacles such as traffic sign poles, ecological landscape trees, guardrail wooden posts or change the running route of the main engine during the operation process, it is necessary to manually check Adjust the attitude position frequently and in time, or adopt the avoidance structure of free rotation suspension and spring reset mechanism for the working device, so that when the working device overcomes obstacles, it will passively deflect at a certain angle and then be reset by the spring to ac...
