[0046] ​​​​​​​​​​​The application will be further described below with reference to the drawings. The following examples are only used to more clearly illustrate the technical solutions of the application, and cannot be used to limit the protection scope of the application. Example 1

[0047] In combination Figures 1-3 , the present embodiment provides a rescue equipment, which comprises a chassis 1, a compound push shovel 3, and a working arm 4;

[0048] The compound push shovel 3 comprises a push shovel part installed on the chassis 1, and a supporting leg part arranged on both sides of the push shovel part, which is configured to be able to extend or retract from the side of the push shovel part;

[0049] The working arm 4 is installed on the chassis 1 through a rotating platform 4-4, and comprises an arm body part and a driving part capable of driving the arm body part to be close to the chassis 1.

[0050] Specifically, the rescue equipment in the present embodiment has at least three states of transportation, driving and working;

[0051] When the rescue equipment is in the transportation state, the supporting leg part can be retracted to a position close to the chassis 1, so as to reduce the area range of the whole vehicle extending to the outside of the chassis 1. In addition, the arm body part of the working arm 4 can be driven by the driving part to be arranged horizontally on the chassis 1, and the front end of the arm body part (for example, a boom 4-3A) extending outside the chassis 1 can be rotated downward to be close to the side wall of the chassis 1 (at this time, the front end of the arm body part is not installed with a tool), so as to further reduce the area range of the whole vehicle extending to the outside of the chassis 1, so that the whole vehicle can meet the space requirements of various transportation modes such as highway, railway and aviation when used for rescue transportation, and the whole vehicle height and length indicators are low.

[0052] When the rescue equipment is in the driving state, the supporting leg part is still in the retracted state, but the part of the working arm 4 extending outside the chassis 1 does not need to be rotated downward to be close, because the equipment in the driving state only needs to meet the space limitation requirements in the width direction, and at this time the front end of the arm body part is already installed with a tool and is not convenient to lower.

[0053] When the rescue equipment is in the working state, each part of the whole vehicle can be flexibly operated according to the working requirements.

[0054] It is worth noting that the working arm 4 in the present embodiment can be applied to excavators, explosive disposal robots, demolition robots and similar products containing the structure of the working arm 4. Meanwhile, the driving part can be a hydraulic cylinder, an electric cylinder or an electric push rod with the same function in the prior art. The working tool can also be configured as a bucket, a rock drill, a gripper, a hydraulic shear, a breaking hammer and the like in the prior art, and has the functions of pushing, excavating, breaking, shearing and rock drilling.

[0055] In addition, the compound push shovel combination integrated with the outrigger can also be arranged at the front or rear of the vehicle body, and can be applied to excavators, bulldozers and the like.

[0056] In addition to the case that the working arm and the compound push shovel are normally installed at the front of the chassis, the overall arrangement of the embodiment can also adopt the case that the working arm and the compound push shovel are installed at the rear of the chassis, so as to realize the mode that the compound push shovel is retracted and the working arm is transversely arranged on the upper part of the vehicle in the transportation state, and the same working function is achieved through the rear working mode. Embodiment 2

[0057] Different from the embodiment 1, the driving part of the embodiment 2 is provided with the upper side of the arm body part.

The boom cylinder 4-1E, the two-section arm cylinder 4-2B and the bucket rod cylinder 4-3B are arranged on the upper side, on the one hand, the working vehicle can conveniently complete the front and lower working work, and on the other hand, the space on the lower side of each arm body is left out, so as to facilitate the posture retraction when the arm body is horizontally placed, reduce the height of the whole machine, and meet the transportation space limitation. At the same time, the material pollution of the execution cylinder is avoided. Embodiment 3

[0059] In combination Figure 4 Different from the embodiment 1, the rescue equipment of the embodiment 3 further includes a range increasing equipment 2, and in order to meet the height and length limitation of the vehicle body in transportation, the rescue equipment of the embodiment 3 can be quickly disassembled and assembled through modular assembly, so as to solve the efficiency requirement of rescue transportation disassembly.

[0067] The electric drive assembly 1-2 in the embodiment is arranged at the rear of the vehicle body, one end of the electric drive assembly 1-2 is mechanically connected with the frame 1-10, and the other end is used for mounting the drive wheel 1-1.

[0068] In addition, the position of the drive wheel 1-1 is higher than that of the load-bearing wheel 1-5, and the whole vehicle adopts four pairs of smaller size load-bearing wheels 1-5. The load-bearing wheels 1-5 are mounted on the swing arms and connected to the frame 1-10 through the swing arms, and three pairs of load-bearing wheels 1-5 (on the left side direction) and swing arms are installed on the side close to the guide wheel 1-9.

[0069] The first and fourth load-bearing wheels 1-5 (the load-bearing wheels 1-5 located on the two sides) adopt the shock absorption combination of oil-gas suspension. The second and third load-bearing wheels 1-5 (the two load-bearing wheels 1-5 located in the middle) adopt the torsion bar 1-6 spring shock absorption form, and are arranged in a staggered manner with the wheels on the opposite side. The guide wheel 1-9 is located at the front of the vehicle body, and the position is level with the height of the drive wheel 1-1. Embodiment 4

[0070] In combination Figure 6The embodiment provides a composite push shovel 3 suitable for the composite push shovel 3 in embodiment 1, the push shovel part of the composite push shovel 3 comprises a main shovel 3-1, the support leg part comprises a support leg body 3-3 and a support leg oil cylinder 3-4, the mounting end parts of the support leg body 3-3 and the support leg oil cylinder 3-4 are hinged to the side part of the main shovel 3-1, the telescopic end of the support leg oil cylinder 3-4 is hinged to the moving end of the support leg body 3-3, and the telescopic movement of the support leg oil cylinder 3-4 can be converted into the rotating movement of the support leg body 3-3, so that the support leg part can be extended or retracted.

[0071] The composite push shovel 3 in the embodiment is arranged at the front part of the vehicle body, and the support leg is integrated on the composite push shovel 3 and thus also located at the front part of the vehicle body. During construction operation, the front effective operation range of the equipment is larger, and the lateral operation stability is higher compared with the rear support leg scheme.

[0072] In the embodiment, the main shovel 3-1 and the frame 1-10 of the chassis 1 are connected through a bulldozing shovel support 3-5 and a connecting rod 3-6, the main shovel 3-1, the bulldozing shovel support 3-5, the connecting rod 3-6 and the frame 1-10 of the chassis 1 jointly constitute a parallel four-bar linkage 3-6 mechanism, and a first driving assembly is further arranged at the frame 1-10 of the chassis 1 and in transmission connection with the parallel four-bar linkage 3-6 mechanism to drive the main shovel 3-1 in the parallel four-bar linkage 3-6 mechanism to lift.

[0073] Understandably, the parallel four-bar linkage 3-6 mechanism adopted in the embodiment can ensure that the angle between the main shovel 3-1 and the horizontal plane is fixed during lifting of the main shovel 3-1, so the support leg bottom foot disc can always keep horizontal with the ground. Meanwhile, since the support leg body 3-3 needs to be extended or retracted according to different states, the stable lifting of the main shovel 3-1 through the parallel four-bar linkage 3-6 mechanism can also make the extension and retraction of the support leg more stable to prevent interference.

[0074] In the embodiment, the first driving assembly comprises a push shovel oil cylinder 3-7 arranged at the frame 1-10 of the chassis 1, and the telescopic end of the push shovel oil cylinder 3-7 is hinged to the bulldozing shovel support 3-5; the telescopic movement of the push shovel oil cylinder 3-7 can be converted into the lifting movement of the main shovel 3-1 in the parallel four-bar linkage 3-6 mechanism, thereby ensuring the stable lifting of the main shovel 3-1.

[0075] In the embodiment, the push shovel support and the connecting rod 3-6 can be detachably mounted on the frame 1-10 of the chassis 1 through a pin shaft as a quick connection mechanism.

[0078] It is worth noting that the hinge points among the movable arm oil cylinder 4-1E, the movable arm 4-1A and the luffing support in the embodiment are not co-pointed, and the hinge point o5 at which the luffing support is connected to the movable arm 4-1A is closer to the hinge point o1 between the luffing support and the rotary table 4-4; at the same time, the movable arm oil cylinder 4-1E is arranged above the movable arm 4-1A.

[0079] Firstly, during the luffing process of the movable arm 4-1A, the luffing support is driven through the hinge point o5 located on the lower side of the luffing support, the luffing angle of the luffing support is large, and the height drops quickly. Thus, the height of the luffing support when the movable arm 4-1A is at a low attitude and horizontal is reduced.

[0080] Secondly, the movable arm oil cylinder 4-1E is hinged to the mounting end of the movable arm oil cylinder 4-1E through the hinge point o6 located on the upper side of the luffing support, so as to shorten the length of the movable arm oil cylinder 4-1E and reduce the stroke of the movable arm oil cylinder 4-1E.

[0081] Thirdly, the movable arm oil cylinder 4-1E is arranged above the movable arm 4-1A, which can leave out the space below the movable arm 4-1A, so as to control the height of the movable arm 4-1A at a low attitude, effectively control the height of the whole machine and improve the transportation convenience.

[0082] In the embodiment, the hinge point o5 of the luffing support is connected to the hinge point o4 of the lower part of the movable arm 4-1A through the luffing connecting rod 4-1B, so as to drive the luffing support to move when the movable arm 4-1A is driven to move by the movable arm oil cylinder 4-1E. The luffing mechanism 4-1 is in the form of four connecting rods 3-6. The specific hinge point distribution diagram is shown in Figure 10 .

[0087] It can be understood that the hinge point o7 of the top end of the boom cylinder 4-1E is co-hinged with the two-section arm 4-2A and the boom 4-1A, and meanwhile, the boom cylinder 4-1E is distributed on the two sides of the boom 4-1A, which improves the structure stress, reduces the weight of the arm support and reduces the failure rate. The two-section arm cylinder 4-2B is arranged between the boom cylinders 4-1E on the two sides, and the mounting end thereof is hinged to the second connecting bracket 4-2C of the rotating table 4-4 through the hinge point o3.

[0088] Specifically, the two-section arm 4-2A is connected with the boom 4-1A through the pin shaft 1F; the telescopic end of the two-section arm cylinder 4-2B is hinged with the two-section arm 4-2A through the pin shaft 2D;
