Drawings
Fig. 1 is a schematic view of the structure of the present invention.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples.
In fig. 1, the front upper support plate 2 and the front lower support plate 10 are arranged at the upper and lower sides in front of the connecting plate 9, and the rear upper support plate 3 and the rear lower support plate 8 are arranged at the left and right sides behind the connecting plate 9; the front swing cylinder 11 is arranged between the front upper supporting plate 2 and the front lower supporting plate 10, and the rear swing cylinder 5 is arranged between the rear upper supporting plate 3 and the rear lower supporting plate 8; a front upper matching plate 1 and a front lower matching plate 12 are arranged on the rear upper and lower sides of the front mounting plate 13, and the front upper matching plate 1 and the front lower matching plate 12 are respectively sleeved at the upper end and the lower end of the front swing cylinder 11; the rear swinging cylinder 5 is arranged between the rear upper matching plate 4 and the rear lower matching plate 7, and the rear upper supporting plate 3 and the rear lower supporting plate 8 are sleeved at the left side and the right side of the rear swinging cylinder 5; one end of the rear upper matching plate 4 and one end of the rear lower matching plate 7 are arranged at the left side and the right side of the front of the rear mounting plate 6.
The central axis of the front swing cylinder 11 is arranged along the up-down direction.
The central axis of the rear swing cylinder 5 is arranged in the left-right direction.
The surface of the front mounting plate 13 far away from the connecting plate 9 is connected with the breaking-in device, and the surface of the rear mounting plate 6 far away from the connecting plate 9 is connected with the second folding arm. Of course, as an alternative, it is also possible to connect the surface of the front mounting plate 13 remote from the coupling plate 9 with the second folding arm and to connect the surface of the rear mounting plate 6 remote from the coupling plate 9 with the breaking-open device.
The steering device is arranged between the breaking and dismantling device of the fire fighting truck and the arm support, and the steering device is also used for enabling the breaking and dismantling device to swing up and down relative to the arm support; like this, the fire engine not only can realize openly breaking open, can also conveniently realize that the side breaks open the function, effectively improves the broken flexibility of tearing open of fire engine.
The steering device can be arranged between the first arm support and the breaking and dismantling device. When the arm support only comprises the first arm support and the breaking-in device is arranged at the tail end of the first arm support, the steering device can be arranged between the first arm support and the breaking-in device, so that the breaking-in device can swing up and down along with the first arm support under the action of the amplitude-variable oil cylinder and can swing left and right relative to the first arm support under the action of the steering device, and the flexibility of the breaking-in position is better. When the arm frame simultaneously comprises the first arm frame and the second arm frame and the breaking and dismantling device is arranged at the tail end of the second arm frame, the steering device can be arranged between the first arm frame and the second arm frame and between the second arm frame and the breaking and dismantling device, so that the breaking and dismantling device can swing up and down relative to the first arm frame along with the second arm frame on one hand, and can swing left and right relative to the first arm frame under the action of the steering device on the other hand, when the steering device is arranged between the first arm frame and the second arm frame, the steering device can enable the second arm frame and the breaking and dismantling device to swing left and right together, and when the steering device is arranged between the second arm frame and the breaking and dismantling device, the steering device can enable the breaking and dismantling device to swing left and right relative to the second arm frame.
The front swing cylinder 11 and the rear swing cylinder 5 are vertically arranged, the steering device forms a universal mechanism capable of realizing combined up-down and left-right swing action, the breaking-in device can be driven by the front swing cylinder 11 to swing left and right relative to the arm support, the breaking-in device can be driven by the rear swing cylinder 5 to swing up and down relative to the arm support, so that the action of the breaking-in device is not limited to the up-down swing driven by the arm support, but can also swing left and right under the driving of the steering device, and can also swing up and down relative to the arm support under the driving of the steering device, and the breaking-in device has more degrees of freedom, so that the breaking-in device can be conveniently lifted to the vicinity of a dangerous source under the driving of the arm support in the process of high-altitude rescue, can carry out breaking-in any direction and any angle, and particularly can conveniently, flexibly and accurately carry out side breaking-in, therefore, the working range can be effectively enlarged, the working efficiency is improved, and the rescue capacity of the fire truck is enhanced.
