[0029] like Figures 1 to 5 As shown, an embodiment of the present invention provides a counterweight feeding machine for engineering machinery, comprising: a base frame 1, a rolling loading and unloading assembly 2, and a pneumatic self-locking assembly 3.

[0031] like Figure 1 As shown, a handrail 102 is fixedly connected to one side of the base frame 1. The base frame 1 is moved by pushing the handrail 102.

[0032] like Figure 1 As shown, a lifting cylinder 103 is hinged to the upper part of the base frame 1, and the piston rod of the lifting cylinder 103 is hinged to the platform 201. The lifting and lowering movement of the base frame 1 is controlled by controlling the extension and retraction of the piston rod of the lifting cylinder 103.

[0033] like Figure 1 As shown, a guide frame 104 is fixedly connected to the top of the base frame 1. The guide frame 104 serves to assemble and fix the guide rail 105 and the handrail 102.

[0034] like Figures 1 to 3 As shown, a pair of guide rails 105 are fixedly connected to the side of the guide frame 104 close to the platform 201. Multiple evenly distributed limiting sliders 106 are slidably mounted on the outer sides of each guide rail 105, and all limiting sliders 106 are fixedly connected to the side of the platform 201. The cooperation between the guide rails 105 and the limiting sliders 106 serves to guide and limit the lifting and lowering of the base frame 1.

[0035] like Figures 1 to 3 As shown, the rolling loading / unloading assembly 2 is mounted above the base frame 1. The rolling loading / unloading assembly 2 includes a loading platform 201, which is slidably mounted above the base frame 1. The loading platform 201 serves to limit the assembly of multiple rotating shafts 202.

[0036] like Figures 1 to 3As shown in the figure, a plurality of groups of uniformly distributed rotating shafts 202 are rotatably assembled in the loading rack 201. The rotating shafts 202 play a role in assembling and limiting the loading rollers 203.

[0037] As shown in the figure, Figures 1 to 3 The outer side of each of the plurality of groups of rotating shafts 202 is fixedly assembled with a loading roller 203. The plurality of loading rollers 203 can support and limit the heavy blocks to be conveyed, and the rolling of the loading rollers 203 can improve the convenience of feeding and discharging the heavy blocks.

[0038] As shown in the figure, Figures 1 to 3 The outer side of the loading roller 203 is sleeved with a plurality of uniformly distributed friction limiting pads 204.

A plurality of uniformly distributed arc-shaped limiting frames 302 are integrally formed below the assembly fixing plate 301, and the plurality of arc-shaped limiting frames 302 are sleeved on the outer side of the rotating shaft 202. The assembly fixing plate 301 and the plurality of arc-shaped limiting frames 302 cooperate to assemble, limit and drive control the locking piston rod 303.

[0042] As shown in the figure, Figures 1 to 2 A pair of locking piston rods 303 are slidingly assembled in each of the plurality of arc-shaped limiting frames 302. One end of each of the pair of locking piston rods 303 located outside the arc-shaped limiting frame 302 is fixedly connected with a friction shoe 304, and the friction shoe 304 is arranged in cooperation with the rotating shaft 202. The rotating shaft 202 is frictionally locked by controlling the friction between the friction shoe 304 and the outer side of the rotating shaft 202.

[0043] As shown in the figure, Figures 4 to 5As shown, a pair of piston control cavities 305 are arranged in each of the plurality of arc-shaped limiting racks 302. The piston control cavities 305 serve to limit and drive the movement of the moving piston block 306.

[0044] As shown, Figures 4 to 5 The moving piston block 306 is fixedly connected to one end of the locking piston rod 303 in the piston control cavity 305, and the moving piston block 306 is in sliding sealing cooperation with the piston control cavity 305. The movement of the moving piston block 306 is controlled by regulating the air pressure in the piston control cavity 305.

[0045] As shown, Figures 4 to 5 The moving piston block 306 is fixedly connected to one end of the locking piston rod 303 in the piston control cavity 305, and the moving piston block 306 is in sliding sealing cooperation with the piston control cavity 305. The movement of the moving piston block 306 is controlled by regulating the air pressure in the piston control cavity 305.

[0046] As shown, Figures 4 to 5 The arc-shaped limiting rack 302 is provided with a flow guide air duct 308, and the two ends of the flow guide air duct 308 are in communication with a pair of piston control cavities 305. The flow guide air duct 308 serves to connect and transport the air duct 309 and the piston control cavity 305.

[0047] As shown, Figures 4 to 5 The assembly fixing plate 301 is provided with a transport air duct 309, and the transport air duct 309 is in communication with a plurality of flow guide air ducts 308. The transport air duct 309 serves to connect and guide the air duct 312 and the plurality of flow guide air ducts 308.

[0048] As shown, Figures 4 to 5 The control air cylinder 310 is fixedly assembled above the assembly fixing plate 301. The volume of the compression air cavity is regulated by the cooperation of the control air cylinder 310 and the compression piston block 311, so that the air in the compression air cavity is transported to the transport air duct 309 along the guide air duct 312.

[0049] As shown, Figures 4 to 5 A pair of compression piston blocks 311 are slidingly assembled in the control air cylinder 310. The volume of the compression air cavity is adjusted by controlling the movement of the pair of compression piston blocks 311.

[0050] As shown, Figures 4 to 5 The control air cylinder 310 and the pair of compression piston blocks 311 cooperate to form a compression air cavity. The air is transported into the guide air duct 312 by adjusting the volume of the compression air cavity.

[0051] As shown, Figures 4 to 5As shown, a guide air pipe 312 connects the control air cylinder 310 and the mounting plate 301. The two ends of the guide air pipe 312 are respectively connected to the compression chamber and the guide air channel 308. The guide air pipe 312 serves to connect the compression chamber and the guide air channel 308, and is used to transport and discharge air from the compression chamber.

[0052] like Figures 4 to 5 As shown, each of the two opposing sides of the pair of compression piston blocks 311 is rotatably fitted with a movable threaded rod 313, which is threadedly connected to the control cylinder 310. This allows the movable threaded rod 313 to drive the compression piston blocks 311 to move under the action of the internal and external threads, as the control end 314 rotates.

[0053] like Figures 4 to 5 As shown, a control end 314 is fixedly connected to one end of the movable threaded rod 313 located outside the control air cylinder 310. The movable threaded rod 313 is driven to rotate by controlling the rotation of the control end 314.

[0054] In practical use, the lifting cylinder 103 piston rod is retracted to control the lowering of the loading platform 201. Then, the counterweight to be fed can be placed above the multiple sets of loading rollers 203. The rotation of the multiple sets of loading rollers 203 makes it easier to load and unload the counterweight.

[0055] After assembly, the loading guide plate 206 can be flipped so that the loading platform 201, multiple sets of loading rollers 203, side guard plate 205 and loading guide plate 206 cooperate to protect and limit the counterweight. Meanwhile, by driving the control end 314 to rotate, a pair of compression piston blocks 311 compress the compression chamber under the action of the moving threaded rod 313. This causes the air in the compression chamber to be transported along the guide air pipe 312, the conveying air channel 309, and multiple guide air channels 308 to multiple piston control chambers 305. When the air pressure in the piston control chamber 305 is greater than the tension of the return spring 307, the locking piston rod 303 drives the friction pad 304 to move under the action of the moving piston block 306. The friction pad 304 locks and fixes the rotating shaft 202 by rubbing against the outside of the rotating shaft 202. This reduces the possibility of the counterweight slipping due to the rolling of multiple load rollers 203 during the lifting and moving of the load platform 201, and improves the safety of loading and unloading the counterweight.

[0056] Subsequently, the base frame 1 is moved to a specified position by lifting the base frame 201 by controlling the piston rod of the lifting oil cylinder 103 to extend outwards, and then the compression piston block 311 is moved by reversely rotating the control end 314, so that the compression air cavity is expanded, and the air in the plurality of piston control cavities 305 flows back to the compression air cavity along the guide air duct 308, the delivery air duct 309 and the guide air pipe 312, at this time, the locking piston rod 303 drives the friction shoe 304 to reset. When the locking piston rod 303 is reset, the counterweight block can be conveniently loaded by rolling the plurality of loading rollers 203.
