Description

Technical Field

[0001] The present invention relates to the technical field of rescue engineering machinery, and in particular to a demolition device. Background Art

[0002] Considering the safety of rescue, the use of manpower for rescue at the scene of building collapse accidents has gradually decreased, while the use of engineering machinery for rescue has increased. Among all kinds of rescue engineering machinery, demolition equipment has become an important trend in the development of rescue engineering machinery at home and abroad due to its advantages such as strong demolition force and rapid operation.

[0003] Since the rescue passages at the scene of the collapse accident are often narrow and tortuous, and secondary collapse is likely to occur, the demolition devices of the related art use methods such as thickening the plate and strengthening the rib plate to improve the anti-smashing ability. However, this will increase the size and weight of the demolition device, which not only affects the rescue efficiency, but also makes it difficult to adapt to the operation requirements of small areas. In addition, the demolition devices of the related art mostly use an integrated casing, which not only increases the size and weight of the demolition device, but also makes it inconvenient to disassemble and repair the demolition device.

[0056] like Figures 1 to 9 As shown, an embodiment of the present disclosure provides a demolition device. The demolition device includes a rotating platform 8, a frame 1, a casing 4, an engine 2 and a radiator 3. The frame 1 is located above the rotating platform 8 and is connected to the rotating platform 8. The casing 4 is located outside the frame 1 and is connected to the rotating platform 8 and the frame 1. The rotating platform 8, the frame 1 and the casing 4 form a first accommodating space 1A. The frame 1 and the casing 4 form a second accommodating space 1B located above the first accommodating space 1A. The engine 2 is located in the first accommodating space 1A, and the radiator 3 is located in the second accommodating space 1B.

[0057] Based on the demolition device provided by the present disclosure, the frame 1 and the casing 4 located on the rotating platform 8 and above the rotating platform 8 are used to form the first accommodating space 1A and the second accommodating space 1B. The first accommodating space 1A is located below the second accommodating space 1B, and the engine 2 is arranged in the first accommodating space 1A, and the radiator 3 is arranged in the second accommodating space 1B. The demolition device is conducive to realizing the upper and lower layered arrangement of the radiator 3 and the engine 2, and is conducive to protecting the engine 2 by using the frame part and the casing part forming the second accommodating space 1B located above the engine 2, the radiator 3, and the frame part and the casing part forming the first accommodating space 1A located on the side of the engine 2, thereby effectively reducing or avoiding the impact of falling objects on the engine 2, and reducing or eliminating the need for other engine protection measures such as thickening the casing or adding ribs.

[0058] like Figure 1 and Figure 2 As shown, in some embodiments, the frame 1 includes a lower frame 11 and an upper frame 12. The lower frame 11 is connected to the rotating platform 8. The rotating platform 8, the lower frame 11 and the housing 4 form a first accommodating space 1A. The upper frame 12 is located above the lower frame 11 and is connected to the lower frame 11. The lower frame 11, the upper frame 12 and the housing 4 form a second accommodating space 1B.

[0059] By combining the lower frame 11 and the upper frame 12 with the casing 4, two independent first accommodating spaces 1A and second accommodating spaces 1B are formed. This design enables the engine 2 and the radiator 3 to be installed in two spaces separated from each other. The lower frame 11 is connected to the rotating platform 8, which helps the rotating platform 8 drive the lower frame 11 to rotate and drive the frame 1 to rotate. The upper frame 12 is located above the lower frame 11 and connected thereto. The frame 1 has a compact structure and is easy to disassemble and install, and is convenient for maintenance.

[0060] like Figure 1 and Figure 2 As shown, in some embodiments, the lower frame 11 includes two lower frame side frame bodies 111 , and the two lower frame side frame bodies 111 are respectively located above the left and right sides of the rotating platform 8 and connected to the rotating platform 8 .

[0061] The two lower frame side frame bodies 111 are conducive to protecting the first accommodating space 1A in the left-right direction, and are conducive to protecting the engine 2 located in the first accommodating space 1A. In addition, the two lower frame side frame bodies 111 are conducive to independent assembly and disassembly, thereby facilitating installation and maintenance. The lower frame side frame body 111 may, for example, include at least one third cross beam 1111, and the third cross beam 1111 extends in the front-rear direction, which is conducive to better protecting the engine 2 from the side.

[0062] like Figure 1 and Figure 2As shown, in some embodiments, the rear ends of the two lower frame side frame bodies 111 are aligned, and one of the front ends of the two lower frame side frame bodies 111 is positioned rearward relative to the other.

[0063] Arranging the front ends of the two lower frame side frame bodies 111 with one of them being relatively backward relative to the other is conducive to a compact structure and improved space utilization. This arrangement is also conducive to enabling maintenance equipment or the operator's hand to extend into the first accommodation space 1A through the front side of the lower frame side frame body 111 at the side of the rescue device, thereby assembling and repairing the engine 2 and other equipment, which is conducive to improving assembly efficiency and maintenance efficiency.

[0064] like Figure 1 and Figure 2 As shown, in some embodiments, the upper portion of the relatively rearward front end of the two lower frame side frame bodies 111 is rearward relative to the lower portion.

[0065] This arrangement is conducive to providing assembly space for components other than the engine 2, and is conducive to making the components in the assembly space easy to access, thereby facilitating the rapid repair of damaged components and improving the maintenance efficiency of the demolition device.

[0066] like Figure 1 and Figure 2 As shown, in some embodiments, the lower frame 11 further includes a lower frame rear connection portion 112 and a lower frame upper connection portion 113. The lower frame rear connection portion 112 is connected between the rear ends of the two lower frame side frame bodies 111. The lower frame upper connection portion 113 is connected between the upper ends of the two lower frame side frame bodies 111.

[0067] The lower frame rear connection portion 112 and the lower frame upper connection portion 113 are connected between the two lower frame side frame bodies 111 , which is beneficial to improving the strength of the lower frame 11 and enhancing the stability of the lower frame 11 .

[0068] like Figure 1 and Figure 2 As shown, in some embodiments, the lower frame rear connection portion 112 includes a first crossbeam 1121 located between the top and bottom of the lower frame 11. The first crossbeam 1121 is an arc-shaped beam with a middle portion protruding backward relative to the left and right sides. The lower frame upper connection portion 113 includes a second crossbeam 1131 located at the front of the lower frame 11. The second crossbeam 1131 is a bent beam with a U-shaped concave portion protruding backward relative to the left and right sides. The lower frame upper connection portion 113, for example, may also include a fourth crossbeam 1132 located at the rear end of the upper portion of the two lower frame side frame bodies 111, which is conducive to improving the structural stability of the upper portion of the lower frame side frame bodies 111.

[0069] The first cross beam 1121 is an arc-shaped beam with a middle portion protruding backward relative to the left and right sides. The arc-shaped beam can more effectively disperse and resist the impact force or load behind the demolition device, thereby facilitating the enhancement of the structural strength and stability of the rear portion of the lower frame 11. In addition, the arc-shaped beam is conducive to expanding the size of the first accommodation space 1A, and is conducive to providing sufficient installation space for the engine 2.

[0070] The second cross beam 1131 is a bent beam with a U-shaped recessed portion in the middle portion which protrudes backward relative to the left and right sides. The bent beam is beneficial for providing a space for convenient installation of other components or systems (such as a mechanical arm, etc.) of the demolition device, which helps to improve the structural compactness of the demolition device and reduce the volume of the demolition device, thereby helping to improve the flexibility of the demolition device in moving in the narrow space at the collapse site.

[0071] like Figure 1 and Figure 2 As shown, in some embodiments, the upper frame 12 includes two upper frame body parts 121 that are parallel and spaced apart. The two upper frame body parts 121 are connected to the upper front part and the upper rear part of the lower frame 11 respectively.

[0072] The upper frame 12 is provided with two independent upper frame body parts 121 at the front and rear, so as to reduce the arrangement of the upper frame 12 in the left and right directions, which is beneficial to improving the lightness of the demolition device and also facilitates the assembly and disassembly of the upper frame 12 .

[0073] like Figure 1 and Figure 2 As shown, in some embodiments, the upper frame body 121 includes an upper frame main board 1211, an upper frame side wing 1212 and an upper frame reinforcement 1213. The upper frame main board 1211 is arranged perpendicular to the front-back direction, with a hole in the middle or a slot in the middle and lower part. The upper frame side wing 1212 is connected to the edge of the upper frame main board 1211 and is arranged perpendicular to the upper frame main board 1211. The upper frame reinforcement 1213 is fixedly connected to the upper frame main board 1211 and the upper frame side wing 1212.

[0074] The upper frame main board 1211 is arranged perpendicularly to the front-to-back direction, which is beneficial to protecting the radiator 3 in the front-to-back direction. The middle opening and the middle and lower slot design of the upper frame main board 1211 are beneficial to reducing weight and providing installation space for installing other components. The upper frame side wings 1212 are connected to the edges of the upper frame main board 1211 and are arranged perpendicularly to the upper frame main board 1211, which is beneficial to forming an L-shaped or T-shaped cross-section of the frame of the upper frame 12, improving the strength of the frame, and enhancing the structural strength and stability of the upper frame 12. The upper frame reinforcement part 1213 is fixedly connected to the upper frame main board 1211 and the upper frame side wings 1212, which is beneficial to further enhance the structural strength and stability of the upper frame 12.

[0075] like Figure 3 As shown, in some embodiments, the housing 4 includes a bottom housing 44 and a top housing 43. The bottom housing 44 is located outside the lower frame 11 and is connected to the rotating platform 8 and the frame 1. The rotating platform 8, the lower frame 11 and the bottom housing 44 form a first accommodation space 1A. The top housing 43 is located outside the upper frame 12 and is connected to the bottom housing 44 and the frame 1. The lower frame 11, the upper frame 12 and the top housing 43 form a second accommodation space 1B.

[0076] The bottom shell 44 and the top shell 43 make the casing 4 a split casing, which is convenient for assembling and disassembling the casing 4, and is convenient for exploring the conditions in the first accommodating space 1A and the second accommodating space 1B by disassembling the top shell 43, and is convenient for repairing or inspecting the inside of the demolition device, thereby improving the maintainability of the demolition device.

[0077] like Figures 3 to 7 as well as Fig. 9 As shown, in some embodiments, the bottom housing 44 includes two side housings 441 and a rear housing 442. The two side housings 441 are respectively located on the left and right sides of the lower frame 11, and are connected to the rotating platform 8 and the lower frame 11. The rear housing 442 is located at the rear side of the lower frame 11, and is connected to the rotating platform 8, the lower frame 11 and the two side housings 441.

[0078] The two side housings 441 and the rear housing 442 form the bottom housing 44 into a split bottom housing, which is convenient for assembling and disassembling the bottom housing 44. The two side housings 441, the rear housing 442, the rotary platform 8 and the lower frame 11 are connected together, which is convenient for improving the connection firmness and stability of the lower structure of the demolition device.

[0079] like Figures 3 to 7 As shown, in some embodiments, the side housing 441 includes a first side housing portion 4411 and a second side housing portion 4412. The first side housing portion 4411 is fixedly connected to the lower frame 11. The second side housing portion 4412 is located below the first side housing portion 4411 and is detachably connected to the first side housing portion 4411. The second side housing portion 4412 is fixedly connected to the rotating platform 8 and the lower frame 11.

[0080] The first side housing part 4411 and the second side housing part 4412 make the side housing 441 a split side housing, which is beneficial to the manufacture, assembly and maintenance of the side housing 441. It is also beneficial that when part of the side housing 441 is damaged, only the damaged first side housing part 4411 or the second side housing part 4412 needs to be replaced, without replacing the entire side housing 441, thereby reducing the maintenance cost. The first side housing part 4411 is fixedly connected to the lower frame 11, which is beneficial to improving the installation stability of the side housing 441. At the same time, the second side housing part 4412 is not only connected to the first side housing part 4411, but also fixedly connected to the rotating platform 8 and the lower frame 11, which is beneficial to further enhance the structural stability of the side housing 441.

[0081] like Figure 3 , Figure 5 and Figure 7 As shown, in some embodiments, the housing 4 further includes at least one angle connector 42. The rotating platform 8 and the second side housing portion 4412 are detachably connected via the angle connector 42. For example, the angle connector 42 is an angle iron, including a first connecting plate and a second connecting plate perpendicular to each other. The angle connector 42 is fixedly connected to the second side housing portion 4412 via the first connecting plate, and is fixedly connected to the rotating platform 8 via the second connecting plate.

[0082] The angle connector 42 has a simple structure and is convenient for flexibly setting the installation position, which is conducive to quickly assembling and disassembling the rotating platform 8 and the second side housing part 4412 through the angle connector 42. In addition, the angle connector 42 is small in size, which is conducive to improving the connection strength between the rotating platform 8 and the second side housing part 4412 by setting multiple angle connectors 42.

[0083] like Figure 6 and Figure 7 As shown, in some embodiments, the edge where the first side housing portion 4411 and the second side housing portion 4412 meet includes a non-straight portion and is shaped to match each other. The non-straight portion may include, for example, a stepped edge portion, a curved edge portion, and the like.

[0084] Through the shape matching of the non-straight portion, the first side housing portion 4411 and the second side housing portion 4412 can form a more complex contact surface when they are joined, which is beneficial to increase the contact area between the two, thereby facilitating the improvement of the structural strength of the side housing 441, and helping the side housing 441 to resist external stress and vibration. In addition, the non-straight portion is beneficial to accurately position and install the first side housing portion 4411 and the second side housing portion 4412.

[0085] like Figure 6 and Figure 7 As shown, in some embodiments, the side housing 441 includes a plug-in portion 4410 and a groove 441A. The plug-in portion 4410 is disposed on one of the bottom of the first side housing portion 4411 and the top of the second side housing portion 4412 and protrudes toward the other. The groove 441A is disposed corresponding to the plug-in portion 4410 and is disposed on the other of the bottom of the first side housing portion 4411 and the top of the second side housing portion 4412. The plug-in portion 4410 is inserted into the groove 441A to connect the first side housing portion 4411 and the second side housing portion 4412.

[0086] The plug-in portion 4410 cooperates with the groove 441A to quickly position and combine the first side casing portion 4411 and the second side casing portion 4412, effectively preventing relative movement between the first side casing portion 4411 and the second side casing portion 4412, which is beneficial to enhancing the connection stability between the first side casing portion 4411 and the second side casing portion 4412, and helps to improve the ability of the side casing 441 to resist external impact and vibration.

[0087] like Figure 5 and Fig. 9 As shown, in some embodiments, the rear housing 442 includes a first positioning portion 4422, and the side housing 441 includes a second positioning portion. The first positioning portion 4422 and the second positioning portion both include positioning surfaces, and the positioning surfaces of the first positioning portion 4422 and the second positioning portion fit each other.

[0088] The first positioning portion 4422 and the second positioning portion are conducive to achieving precise positioning of the rear shell 442 and the side shell 441 through the fit of the positioning surfaces during assembly, without the need for excessive adjustment and calibration, which is conducive to simplifying the assembly process, improving assembly efficiency, and also helping to improve the connection stability between the rear shell 442 and the side shell 441.
