[0030] Please refer to Figure 1 The present embodiment provides an engineering machine 1000, which includes an engineering machine 1000 body and a variable amplitude piercing device 100 connected to the engineering machine 1000 body. Specifically, in the present embodiment, the engineering machine 1000 is a ladder truck. In other embodiments, the variable amplitude piercing device 100 can be used for various engineering machines or engineering vehicles with a climbing and demolition function, such as an aerial work vehicle.

[0031] Please refer to Figure 1 and Figure 2, the variable amplitude piercing device 100 includes a ladder frame seat 10, a lower ladder frame 20 and an upper ladder frame 30. The ladder frame seat 10 is fixedly mounted on the top of the carriage of the engineering machinery 1000 body. One end of the lower ladder frame 20 and one end of the upper ladder frame 30 are rotatably connected. Specifically, the lower ladder frame 20 and the upper ladder frame 30 are hinged to each other. A demolition punch 40 is provided at the end of the upper ladder frame 30 away from the lower ladder frame 20. A first driving member 21 is connected between the lower ladder frame 20 and the upper ladder frame 30. The first driving member 21 is used to drive the relative rotation between the lower ladder frame 20 and the upper ladder frame 30. In this embodiment, the length of the lower ladder frame 20 is greater than the length of the upper ladder frame 30, so that the demolition punch 40 can achieve a larger variable angle range while rising to a certain height.

[0032] Furthermore, in order to adjust the angle of the demolition punch 40 while adjusting the angle of the upper ladder frame 30 , the demolition punch 40 has a direction that is consistent with the length direction of the upper ladder frame 30 .

[0033] It is understandable that one end of the lower ladder frame 20 is hinged to the ladder frame seat 10, so that the lower ladder frame 20 can rotate around the ladder frame seat 10 in a vertical plane, thereby adjusting the height of the upper ladder frame 30 relative to the body of the engineering machinery 1000. The upper ladder frame 30 and the lower ladder frame 20 can rotate relative to each other, and the first driving member 21 drives the upper ladder frame 30 to rotate around the lower ladder frame 20, thereby adjusting the angle of the upper ladder frame 30 relative to the horizontal plane, thereby achieving the angle adjustment of the demolition punch 40. When it is necessary to demolish a high wall or panel, the variable amplitude piercing device 100 can adapt to walls of different angles, so that the sprint direction of the demolition punch 40 can be perpendicular to the wall.

[0034] Please refer to Figure 4 In this embodiment, the variable amplitude puncture device 100 further includes a ladder frame seat 10. The lower ladder frame 20 is rotatably mounted on the ladder frame seat 10.

[0035] Further, the ladder frame seat 10 includes a ladder frame seat 10 body and a turntable (not shown). The turntable is installed on the top of the engineering machinery 1000 body. The ladder frame seat 10 body is rotatably connected to the turntable. The ladder frame seat 10 body can rotate relative to the turntable along a first rotation direction. The first rotation direction is located in a horizontal plane, and the lower ladder frame 20 is rotatably connected to the ladder frame seat 10 body. The lower ladder frame 20 can rotate relative to the ladder frame seat 10 body along a second rotation direction. The second rotation direction is located in a vertical plane. It can be understood that the lower ladder frame 20 can rotate in a horizontal plane relative to the engineering machinery 1000, and at the same time rotate in a vertical plane relative to the ladder frame seat 10.

[0036] Please refer to Figure 2Optionally, in this embodiment, the first driving member 21 is a cylinder. The cylinder barrel of the cylinder is installed on the lower ladder frame 20, and one end of the piston rod of the cylinder is fixedly connected to the upper ladder frame 30. In other embodiments, the first driving member 21 can also be a pneumatic cylinder or an electric cylinder, which is not limited by the present invention.

[0037] Specifically, in this embodiment, the upper ladder frame 30 and the lower ladder frame 20 are hinged through a first hinge point, the fixed end of the cylinder of the first driving member 21 is hinged to the lower ladder frame 20 through a second hinge point, and the movable end of the piston rod of the first driving member 21 is hinged to the upper ladder frame 30 through a third hinge point. When the first driving member 21 pushes the upper ladder frame 30, the upper ladder frame 30 rotates relative to the lower ladder frame 20 through the first hinge point.

[0038] Please refer to Figure 4 In order to make the upper ladder frame 30 basically parallel to the horizontal plane, so that the upper ladder frame 30 forms an elevated platform for firefighters to climb up to fight fires in high-rise buildings, tall facilities, oil tanks, etc., rescue trapped people, rescue valuable materials and complete other rescue tasks, in this embodiment, when the lower ladder frame 20 rotates around the ladder frame seat 10, the upper ladder frame 30 always remains basically parallel to the horizontal plane. It can be understood that when the demolition surface needs to be demolished, the angle of the upper ladder frame 30 can be freely adjusted. When the demolition is completed, when the firefighters need to climb up, the upper ladder frame 30 remains basically parallel to the horizontal plane, thereby forming an elevated platform.

[0039] Please continue to refer to Figure 2 The demolition punch 40 includes a punch body 42 and a telescopic arm 41. One end of the telescopic arm 41 is fixedly connected to the upper ladder frame 30, and the other end of the telescopic arm 41 is fixedly connected to the punch body 42. The length of the telescopic arm 41 can be adjusted so that the punch body 42 can be extended or retracted relative to the upper ladder frame 30. It can be understood that when it is necessary to demolish the demolition surface, the telescopic arm 41 is extended, and the punch body 42 is extended relative to the upper ladder frame 30 to stab and demolish the demolition surface; when the demolition is completed, the telescopic arm 41 is shortened, and the punch body 42 is retracted relative to the upper ladder frame 30, so as to facilitate the firefighters to carry out rescue operations.

[0040] Furthermore, in order to enhance the sprinting and demolition effect, the variable amplitude piercing device 100 further includes a second driving member (not shown). The second driving member is used to drive the demolition punch 40 to vibrate along the length direction of the demolition punch 40. It can be understood that the second driving member drives the demolition punch 40 to reciprocate rapidly in a direction perpendicular to the demolition surface, thereby causing frequent impacts on the demolition surface and realizing rapid destruction of the demolition surface. Specifically, the second driving member is a cylinder.

[0041] Please refer to Figure 3The variable amplitude puncture device 100 of this embodiment also has a lighting function, and a lighting lamp 31 is also provided on the upper ladder frame 30. The lighting lamp 31 is rotatably mounted on the upper ladder frame 30. It is understandable that the lighting lamp 31 is mounted on the upper ladder frame 30, and the angle of the lighting lamp 31 relative to the upper ladder frame 30 remains unchanged. The upper ladder frame 30 can be driven to rotate relative to the lower ladder frame 20 by the first driving member 21, thereby adjusting the angle of the lighting lamp 31 relative to the lower ladder frame 20, thereby adjusting the irradiation angle of the lighting lamp 31. Furthermore, the staff can further fine-tune the irradiation angle of the lighting lamp 31 by adjusting the angle between the lighting lamp 31 and the upper ladder frame 30.

[0042] In this embodiment, the number of the illuminating lamps 31 is four, which are respectively installed on both sides of the upper ladder frame 30. In other embodiments, the number of the illuminating lamps 31 can be two, three, six, etc., which is not limited by the present invention.

[0043] Furthermore, the variable amplitude piercing device 100 further includes a high-pressure water gun 50, which includes a nozzle 51 and a water pipe 52 connected to the nozzle 51. The nozzle 51 is detachably mounted on the lower ladder frame 20 and can be removed when in use. One end of the water pipe 52 away from the nozzle 51 is connected to a water tank (not shown) of the engineering machinery 1000 body for water supply.

[0044] Please refer to Figure 4 Furthermore, a ladder 22 is provided on the lower ladder frame 20 along the length direction of the lower ladder frame 20 for firefighters to go up and down the ladder.

[0045] The beneficial effects of the variable amplitude puncture device 100 of the engineering machinery 1000 provided by the embodiment of the utility model are:

[0046] The variable amplitude piercing device 100 of the utility model comprises a lower ladder frame 20 and an upper ladder frame 30. One end of the lower ladder frame 20 and one end of the upper ladder frame 30 are rotatably connected. An end of the upper ladder frame 30 away from the lower ladder frame 20 is provided with a demolition punch 40. A first driving member 21 is connected between the lower ladder frame 20 and the upper ladder frame 30. The first driving member 21 is used to drive the relative rotation between the lower ladder frame 20 and the upper ladder frame 30. The length of the lower ladder frame 20 is greater than the length of the upper ladder frame 30. By arranging the first driving member 21 between the upper ladder frame 30 and the lower ladder frame 20, when the lower ladder frame 20 rotates around the ladder frame seat 10, the first driving member 21 drives the upper ladder frame 30 and the lower ladder frame 20 to rotate relative to each other, thereby realizing that the demolition sprint angle of the demolition punch 40 is adjustable. When demolition surfaces of different angles need to be demolished, the angle of the demolition punch 40 can be adjusted to achieve the best demolition effect. The variable amplitude puncturing device 100 can adjust the angle of the breaking and puncturing, quickly realize the breaking and puncturing direction to be perpendicular to the breaking surface, and achieve a better breaking and puncturing effect.
