Detailed Description
As can be seen from fig. 1 to 3, the adaptive rear reverse top wheel device for the high beam guy cable basket walking disclosed in the present embodiment includes a reverse top wheel 1, a movable member 2, a fixed member 3, a jacking device 4, and a safety pin 5.
The fixed component 3 is a guide sleeve with a central round hole, is vertically arranged and is fixed at the rear part of a main beam of the guy cable hanging basket.
The jacking device 4 adopts an oil cylinder, the oil cylinder is arranged in the fixed component 3 with a piston rod upwards, and the axial center lines of the oil cylinder and the fixed component are superposed.
The lower part of the movable component 2 is a guide section matched with the inner cavity of the fixed component 3, and the upper end of a piston rod of the jacking device 4 is connected with the bottom surface of the guide section.
The movable component 2 is matched with the inner cavity of the fixed component 1 by taking the guide section as a guide column to stably slide along the fixed component 3, namely the clearance between the movable component and the fixed component is as small as possible, and the movable component is prevented from shaking when sliding along the fixed component.
The position, corresponding to the maximum stroke, of the piston rod of the oil cylinder on the movable component 2 is vertically connected with a safety pin 5, and the length of the safety pin is larger than the outer diameter of the fixed component 3. I.e. the maximum height of the sliding descent of the mobile member 2 in the fixed member 1 is limited by the safety pin 5 to prevent the unrestrained descent of the mobile member 2 from causing the danger of overturning the cable basket in the event of failure of the jacking means 4.
In order to ensure the supporting stability of the reverse ejection wheel, two groups of the device are arranged at intervals at the rear part of the same main beam of the guy cable hanging basket, as shown in figure 2.
The jacking speed of the jacking device of the device can be set, and the hydraulic oil flow rate of the jacking device of the device and the hydraulic oil flow rate of the C-shaped hanging leg driving oil cylinder in the middle part are adjusted through the hydraulic control system, so that the ratio of the jacking speed of the jacking device of the device to the jacking speed of the C-shaped hanging leg driving oil cylinder is equal to the gradient value of the variable-height beam bottom plate, and the horizontal posture of the guy rope hanging basket in the forward moving process can be ensured all the time.
From the above structure of the device it can be seen that it has the following advantages:
1. the anti-ejecting wheel support adopts a structural form of a guide pillar and a guide sleeve, so that the stability of the anti-ejecting wheel support in the lifting process can be effectively ensured, and the walking safety of the guy rope hanging basket is better ensured. In the process of walking the guyed traveler of the variable height beam, the height position of the anti-top wheel is synchronously jacked and adjusted through the two oil cylinders, so that the anti-top wheel can stably walk along the inclined bottom plate of the variable height beam, the cradle can always keep a horizontal posture in the walking process, and the problem that the cradle is integrally inclined when the anti-top wheel walks on the inclined plane of the variable height beam bottom after the guyed traveler in the prior art is effectively solved.
2. The anti-ejecting wheel support adopts a structural form of a guide pillar and a guide sleeve, so that the stability of the anti-ejecting wheel support in the lifting process can be effectively ensured, and the walking safety of the guy rope hanging basket is better ensured.
3. Two sets of the device are arranged at the rear part of the same main beam of the guy cable hanging basket, so that the supporting surface of a rear fulcrum in the walking process of the guy cable hanging basket is enlarged, and the walking process of the hanging basket is safer and more stable.
4. The safety pin is arranged on the guide post according to the jacking stroke of the oil cylinder, so that the hanging basket is ensured not to be seriously inclined under the condition that the jacking of the hydraulic oil cylinder fails, and the construction safety is further ensured.
