[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0029] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 The utility model provides a technical solution: an outboard motor pneumatic lifting device, comprising a chassis 1, a cylinder 3 is movably mounted on the left end of the chassis 1, the chassis 1 is used to provide a mounting carrier for the cylinder 3 and other components, the cylinder 3 is used to provide a lifting driving force, and a swing rod 31 located in the chassis 1 is set on the right end of the cylinder 3, and the two first elastic members 11 are connected to the cylinder 3 through the swing rod 31, and then the two first elastic members 11 whose other ends are set at the bottom end of the chassis 1 are symmetrically mounted on the right end of the swing rod 31, and the two first elastic members 11 are used together to assist the lifting operation, and the first elastic member 11 can be a spring;

[0030] The upper arm 2 located on the upper side of the cylinder 3 and movably arranged at the left end of the base frame 1 is rotatably connected to the lateral parts of the two L-shaped plates 5, and the lower arm 4 located on the lower side of the fixed part of the cylinder 3 and connected to the movable part of the cylinder 3 at the left end is movably installed on the left end of the base frame 1, and then the vertical parts of the two L-shaped plates 5 are rotatably connected to the front and rear ends of the lower arm 4 respectively, and the upper arm 2, the lower arm 4, the base frame 1 and the two L-shaped plates 5 form a quadrilateral movable frame structure;

[0031] The upper rectangular column 52 located at the lower side of the lower support arm 4 is installed between the two L-shaped plates 5, and a mounting carrier is provided for the lower rectangular column 51 through the upper rectangular column 52, and the lower rectangular column 51 located at the lower side of the L-shaped plate 5 is rotatably connected to the lower end of the upper rectangular column 52, and a mounting carrier is provided for the U-shaped frame 7 through the lower rectangular column 51, and then the U-shaped frame 7 is installed on the front end of the lower rectangular column 51, and a processing carrier is provided for the upper card slot 71 and other components through the U-shaped frame 7;

[0032] The two cross beams 65 are symmetrically arranged on the lower right end of the trolley 6. The two cross beams 65 are used in combination to connect the trolley 6 and the U-shaped frame 7. The upper end surfaces of the two transverse parts of the U-shaped frame 7 are both recessed downward to form upper clamping grooves 71. The cross beam 65 located on the upper side passes through the two upper clamping grooves 71. The two upper clamping grooves 71 are used in combination to provide a clamping space for the cross beam 65 located on the upper side. The left end surfaces of the two transverse parts of the U-shaped frame 7 are recessed to the right to form a lower clamping groove 75. The cross beam 65 located on the lower side passes through the two lower clamping grooves 75. The two lower clamping grooves 75 are used in combination to provide a clamping space for the cross beam 65 located on the lower side.

[0033] When in use, the cylinder 3 is started, so that the quadrilateral movable frame structure formed by the lower arm 4, the upper arm 2, the bottom frame 1 and the two L-shaped plates 5 is lifted, and then the U-shaped frame 7 and the two crossbeams 65 are lifted, so that the cart 6 is lifted, and the two first elastic members 11 are initially in a stretched state, so that the first elastic members 11 themselves have elastic force. When the quadrilateral movable frame structure just performs the lifting movement, the elastic force of the first elastic member 11 will apply a pulling force to the swing rod 31, and then apply a pulling force to the quadrilateral movable frame structure, effectively assisting the use of the cylinder 3 to drive the lifting movement, and effectively ensuring the lifting operation of the cart 6;

[0034] When the trolley 6 is lifted to the limit position, the upper rectangular column 52 is rotatably connected to the lower rectangular column 51, so the trolley 6 can be rotated, so that the two cross beams 65, the U-shaped frame 7 and the lower rectangular column 51 are rotated, so that the trolley 6 is rotated 90°, and the trolley 6 can be stored, the space of the fire truck compartment is effectively and reasonably utilized, and the mechanical lifting operation of the trolley 6 equipped with an outboard motor is realized, which effectively ensures that one person can complete the picking and placing operation, and effectively saves human resources.

[0035] like Figure 4 and Figure 5 As shown, the rotating shaft 74 is rotatably connected between the two transverse parts of the U-shaped frame 7, and the rotating shaft 74 provides a mounting carrier for the two C-shaped clamping plates 73, and the two C-shaped clamping plates 73 whose center lines coincide with the center lines of the lower clamping groove 75 are symmetrically mounted on the outer ends of the rotating shaft 74. The two C-shaped clamping plates 73 are used in conjunction to restrict the installation between the crossbeam 65 and the lower clamping groove 75;

[0036] The first connecting rod 76 located on the upper side of the C-shaped card plate 73 is set between the two horizontal parts of the U-shaped frame 7, and the second connecting rod 77 located on the upper side of the rotating shaft 74 is installed between the two C-shaped card plates 73. The first connecting rod 76 is used in conjunction with the first connecting rod 76 to provide a mounting carrier for the second elastic member 72, and then the second elastic member 72 is set between the first connecting rod 76 and the second connecting rod 77. The C-shaped card plate 73 is rotated back to its original position through the second elastic member 72. The second elastic member 72 can be a spring.

[0037] When in use, the cross beam 65 at the lower side is first inserted into the two lower slots 75 to make the U-shaped frame 7 and the cart 6 clamped together, and in the process of the cross beam 65 at the lower side being inserted into the lower slot 75, the cross beam 65 at the lower side first contacts the upper ends of the two C-shaped clamping plates 73, and then the clamping movement of the cross beam 65 at the lower side causes the two C-shaped clamping plates 73 to rotate downward along the rotating shaft 74, and causes the second connecting rod 77 to move, thereby stretching the second elastic member 72, so that the second elastic member 72 generates elastic force;

[0038] When the cross beam 65 on the lower side is inserted into the two lower slots 75, the two C-shaped clips 73 are separated from the cross beam 65 on the lower side, and under the elastic force of the second elastic member 72, the two C-shaped clips 73 are rotated back to their original positions. At this time, the cross beam 65 on the lower side passes through the inner cavities of the two C-shaped clips 73, and the two C-shaped clips 73 are used to limit the installation between the cross beam 65 on the lower side and the two lower slots 75, thereby effectively reducing the probability of separation between the U-shaped frame 7 and the cart 6 due to shaking and other movements, and effectively ensuring the stability of the connection between the cart 6 and the U-shaped frame 7.

[0039] like Figure 1 and Figure 3 As shown, two transversely arranged mounting columns 61 are symmetrically arranged on the upper right end of the cart 6. The mounting columns 61 provide a mounting carrier for the handle 64, and the handle 64, which is located on the left side of the L-shaped plate 5 and on the upper side of the U-shaped frame 7 and is vertically arranged, is rotatably connected to the right end of the mounting column 61. The mounting column 61 cooperates with the handle 64 to move the cart 6. Then the arc plate 62 is installed on the upper left end of the handle 64, and the convex block 63 attached to the lower end of the arc plate 62 is set on the right end of the cart 6. The arc plate 62 and the convex block 63 cooperate to limit the installation of the handle 64.

[0040] When in use, the handle 64 is first pulled outward, thereby moving the arc plate 62 outward, so that the arc plate 62 is separated from the convex block 63, and the handle 64 is rotated 90 degrees. At this time, the handle 64 and the mounting column 61 form a push handle structure, and then the push handle structure is used to push the cart 6;

[0041] When not in use, first push the handle 64 inward to rotate the handle 64 to its original position and make the arc plate 62 contact with the convex block 63 again. At this time, a friction coefficient is generated between the arc plate 62 and the convex block 63, so that the handle 64 can be installed in a restricted manner, effectively avoiding the probability of the handle 64 swinging randomly during movements such as lifting, and protecting the handle 64.

[0042] like Figure 1 and Figure 6 As shown, the screw rod 14 is rotatably connected between two C-shaped plates 16 located at the front and rear sides of the chassis 1 and arranged oppositely. The two C-shaped plates 16 are used in conjunction to provide a mounting carrier for the screw rod 14 and other components, and the nut seat 13 installed at the lower end of the chassis 1 is connected to the outer end of the screw rod 14 through a ball nut pair. The nut seat 13 and the screw rod 14 are used in conjunction to make the chassis 1 move forward and backward, and then the output shaft of the driving device whose fixed part is set at the middle of the front end of the C-shaped plate 16 located on the front side is connected to the screw rod 14, and the screw rod 14 is driven to rotate through the driving device, and the driving device can use a motor 17;

[0043] Two round rods 15 located on the left and right sides of the screw rod 14, penetrating the nut seat 13 and slidably connected to the nut seat 13, are symmetrically installed between the two C-shaped plates 16. The two round rods 15 are used in combination to guide the movement of the nut seat 13, and two bottom plates 12 slidably connected to the left and right ends of the nut seat 13 and the lower end of the base frame 1 are symmetrically installed between the two C-shaped plates 16. The two bottom plates 12 are used in combination to lift the base frame 1.

[0044] When the trolley 6 is dropped to the ground, the trolley 6 will be separated from the U-shaped frame 7, and then the motor 17 will be started to drive the screw rod 14 to rotate. Since the screw rod 14 is connected to the nut seat 13 by a ball nut pair, the rotation of the screw rod 14 will cause the nut seat 13 to move, and then the base frame 1 will move along the bottom plate 12, so that the structure formed by the upper support arm 2, the lower support arm 4, the cylinder 3, the L-shaped plate 5 and the U-shaped frame 7 and other components will move, so as to achieve the dislocation movement of the structure and the trolley 6, which is effective and convenient for personnel to operate the trolley 6.

[0045] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
