[0037] The working principle of the above-mentioned crawler assembly installation structure is:

[0038] First, before using this application, the staff first electrically connects the first driving member 26 and the second driving member 241 to the external control terminal through cables, and connects the first cylinder 210 and the third cylinder 294 to the external gas source through pipelines;

[0039] Second, during the installation of the crawler track, the staff here screws the installation spindle 21 into the hole groove at the middle end of the side of the wheel frame plate 13, and installs the pressing side plate 23 and the pressure rod side plate 24 on the front and rear sides of the installation spindle 21 through the hinge frame 22, and then adjusts the relative posture of the pressing side plate 23 and the pressure rod side plate 24 through the hinge action of the hinge frame 22, and makes them parallel to the front and rear sides of the wheel frame plate 13;

[0040] Third, the staff then places the central shaft 116 inside the screw barrel 291, and supplies energy to the first cylinder 210 and the third cylinder 294 through an external air source, so that the first cylinder 210 first clamps and fixes the central shaft 116, and then controls the first driving member 26 and the second driving member 241 to drive synchronously through the control terminal, so that the first driving member 26 and the second driving member 241 drive the screw barrel 291 and the second adjusting screw 28 to rotate respectively by driving the bevel gear set 27 on the side thereof, so that the second adjusting screw 2 8 is threadedly driven with the side ear plates of the pressing side plate 23 and the pressure rod side plate 24, and drives the slide plate 25 to slide on the pressing side plate 23 and the pressure rod side plate 24 for micro-adjustment, and then the middle shaft 116 and the insertion rod 243 are respectively inserted into the annular body on the side of the adjacent chain plate 111, and then the second adjustment screw 28 is driven by the first driving member 26 and the second driving member 241 to perform threaded transmission to drive the slide plate 25 to adjust, so as to pull the two groups of chain plates 111 at the broken part of the crawler track closer to each other, so as to reduce the external equipment required for pulling and reduce the installation cost;

[0041] Fourth, when the middle shaft 116 and the insertion rod 243 pull the two adjacent groups of chain plates 111 to the assembly position, the third cylinder 294 is energized to clamp and fix the middle shaft 116, and the first cylinder 210 is controlled to stop clamping the middle shaft 116, and then the screw barrel 291 is rotated through the transmission action of the first driving member 26 and the bevel gear set 27. Here, due to the plug-in fixation of the middle shaft 116 and the side annular body of the chain plate 111, the screw sleeve 292 and the screw barrel 291 are screwed inwardly by thread transmission. Here, the electromagnetic clutch on the side ear plate of the slide plate 25 is controlled to be powered off, so that the screw sleeve 292 pushes the middle shaft 116 in the side annular body of the chain plate 111 through the third cylinder 294 and the pressure block 295 to slide and assemble;

[0042] Fifth, when the middle shaft 116 slides to the rear end of the side ring body of the adjacent two sets of chain plates 111, it squeezes the plug rod 243 and the second cylinder 242. Here, the air pressure inside the second cylinder 242 is monitored in real time by the sensor on the side of the second cylinder 242. When the air pressure value reaches a certain value, the air outlet of the second cylinder 242 is opened to make the middle shaft 116 push the plug rod 243 out of the side ring body of the chain plate 111, and the middle shaft 116 is inserted and fixed on the side of the adjacent chain plate 111; then, through the hinge frame 22 The adjustment action will rotate the pressed side plate 23 and the pressure rod side plate 24 to other workstations, and the staff will screw the limit screw 115 into the screw ring on the side section of the chain plate 111. Here, the limit screw 115 provides a limit locking action for the central axis 116. Finally, the staff will install the cover plate 114 on the top of the side section of the chain plate 111 to complete the assembly action. The staff will then use an external tool to drive the first adjustment screw 112 to rotate and adjust the spatial position of the locking block 113 to adapt to its locking structure with the track wheel 12.

[0043] The present invention provides an improved track assembly installation structure, which adapts to the locking structure between the track wheel 12 by setting the adjustment action of the first adjusting screw 112 and the locking block 113 in the track assembly 11, thereby reducing the jamming phenomenon between the wheel and the belt during installation; the screw sleeve assembly 29 and the second adjusting screw 28 are driven to rotate through the meshing transmission action of the first driving member 26 and the second driving member 241 and the bevel gear group 27, respectively realizing the displacement adjustment of the second adjusting screw 28 and the extrusion action of the rod body of the screw sleeve assembly 29, and the displacement of the second adjusting screw 28 can pull the two groups of chain plates 111 at the broken part of the track closer to each other, so as to reduce the external equipment required for pulling and reduce the installation cost, and the screw sleeve assembly 29 can realize the full-automatic sliding assembly of the central shaft 116 to improve the assembly efficiency.
