Two guide grooves 4077 are symmetrically provided inside the support platform 4073. The upper and lower sides of the guide groove 4077 respectively penetrate the upper and lower surfaces of the support platform 4073. A guide block 4078 is slidably installed inside the guide groove 4077. A side support roller 4079 is installed on the top of the guide block 4078. The two side support rollers 4079 are respectively in contact with the inner and outer side walls of the conveyor belt 201. A first support roller 4079 is provided below the inner limit roller 404. The support plate 403 supports the conveyor belt 201. At the same time, support platforms 4073 are symmetrically arranged on both sides of the first support plate 403 to support the conveyor belt 201 between the outer limiting roller 106 and the inner limiting roller 404. The two side support rollers 4079 symmetrically arranged on the support platform 4073 are in contact with the inner and outer side walls of the conveyor belt 201 respectively, further improving the movement stability of the conveyor belt 201, thereby improving the conveying stability. An auxiliary support unit 408 is arranged between the two guide blocks 4078. The two first support A guide cylinder 4075 and a guide rod 4076 are respectively installed on the two support platforms 4073 corresponding to the plate 403. The guide cylinder 4075 is slidably connected with the guide rod 4076, and the two side support rollers 4079 on the support platform 4073 limit the conveyor belt 201, so that the inclination angle of the conveyor belt 201 between the four outer limiting rollers 106 and the inner limiting roller 404 is guaranteed to be consistent, thereby improving the conveying stability and avoiding the conveying stability caused by the displacement of the conveyor belt 201 under the action of pressure when the crawler shoe is conveyed to one side.

[0042] The auxiliary support unit 408 includes a rod groove 4081 provided on the support platform 4073, the rod groove 4081 is located between the two guide grooves 4077, a longitudinal rod 4082 is movably installed inside the rod groove 4081, a second support plate 4083 is fixedly installed on the top of the longitudinal rod 4082, the second support plate 4083 contacts the bottom wall of the conveyor belt 201, a movable groove 4084 is provided inside the longitudinal rod 4082, a pressure rod 4085 is movably installed inside the movable groove 4084, a compression spring 4086 is fixedly installed between the top wall of the pressure rod 4085 and the bottom wall of the second support plate 4083, a bottom plate 4087 is fixedly installed at the bottom end of the pressure rod 4085, connecting rods 4088 are symmetrically hingedly installed at both ends of the bottom plate 4087, and the other ends of the two connecting rods 4088 They are hinged to the bottom walls of the two guide blocks 4078 respectively. When the two support seats 101 move away from each other, the inclination angle of the conveyor belt 201 between the outer limiting roller 106 and the inner limiting roller 404 continues to increase, so that the supporting area of ​​the inner limiting roller 404 on the conveyor belt 201 is reduced, and the inclination angle of the conveyor belt 201 increases, pressing the two side support rollers 4079 to move away from each other, so that the pressure rod 4085 moves upward and the compression spring 4086 is compressed. Under the action of the elastic force of the compression spring 4086, the larger the inclination angle of the conveyor belt 201, the greater the supporting force of the second support plate 4083 on the conveyor belt 201, so that the supporting effect of the second support plate 4083 on the conveyor belt 201 complements the supporting effect of the first support plate 403 on the conveyor belt 201, further ensuring the conveying stability.

[0043] Working principle: When working, first adjust the two support platforms 203 on the conveyor belt 201 to be located near two adjacent workstations where the track plate of the excavator is processed, and when the two first motors 105 are turned on synchronously, the two pulleys 104 rotate synchronously, and then drive the conveyor belt 201 to move, so that the support platform 203 moves with the conveyor belt 201 to transport;

[0044] After the track shoe of the excavator is processed at the current workstation, the track shoe of the excavator is placed on the support platform 203 close to this workstation through the lifting equipment. At this time, the support platform 203 is located at the end position of the support seat 101 close to this workstation, and then the support platform 203 moves to the end position of another support seat 101 along with the conveyor belt 201, so that the track shoe of the excavator is moved to the position close to the next workstation, and the other support platform 203 moves to the position close to the previous workstation for re-feeding and conveying. When the track shoe of the excavator moves to the position close to the next workstation, the first motor 105 stops to stop the conveyor belt 201 from moving, and the track shoe of the excavator is grabbed by the grabbing device and taken to the next processing workstation;

[0045] When the distance between two adjacent workstations for processing the crawler plate of the excavator is far, it is necessary to adjust the distance between the two support platforms 203. At this time, the second motor 305 is turned on to drive the double-headed screw 304 to rotate. Since the sliding blocks 303 at the bottom ends of the two support seats 101 are respectively threadedly connected with the thread grooves in opposite directions on the double-headed screw 304, the two support seats 101 are driven to move away from each other until the positions of the two support platforms 203 move to correspond to the two workstations. When the two support seats 101 are moving away from each other, under the action of the conveyor belt 201, the two inner limiting rollers 404 approach each other, and under the elastic force of the compression spring 406, the conveyor belt 201 is in a tensioned state, thereby ensuring the conveying stability of the crawler plate of the excavator.

[0046] As the distance between the two support seats 101 gradually increases, the distance between the two inner limiting rollers 404 continues to decrease, so that the conveyor belt 201 between the outer limiting roller 106 and the inner limiting roller 404 continues to tilt, and the conveyor belt 201 is located on the second support plate 4083, and the two side support rollers 4079 on both sides are in contact with the inner and outer side walls of the conveyor belt 201 respectively, so as to limit the conveyor belt 201 and further improve the conveying stability. As the inclination angle of the conveyor belt 201 between the two side support rollers 4079 increases, under the action of the conveyor belt 201, the two side support rollers 4079 are continuously separated, and the two The side support rollers 4079 move away from each other, and the pressure rod 4085 is pulled upward by the two bottom plates 4087, so that the compression spring 4086 is continuously compressed, so that the support force of the second support plate 4083 on the conveyor belt 201 is continuously increased, so that as the inclination angle of the conveyor belt 201 between the outer limiting roller 106 and the inner limiting roller 404 is continuously increased, the wrap angle of the conveyor belt 201 to the inner limiting roller 404 is reduced, and when the support area of ​​the first support plate 403 on the conveyor belt 201 is reduced, the support force of the second support plate 4083 on the conveyor belt 201 is continuously increased, thereby improving the conveying stability of the excavator crawler shoe;

[0047] At the same time, since the two corresponding support platforms 4073 on the two first support plates 403 are respectively installed with guide cylinders 4075 and guide rods 4076, the guide rods 4076 are slidably installed inside the guide cylinders 4075, so that the positions of the sliding blocks 4074 in the sliding grooves 4072 are the same, and the conveyor belt 201 is limited by the two side support rollers 4079, so that the inclination angles of the conveyor belt 201 between the four outer limiting rollers 106 and the inner limiting roller 404 remain the same, avoiding the sliding of the slider 405 when the excavator track shoe is transported close to the inner limiting roller 404 on one side, causing the limiting shape of the conveyor belt 201 to be deformed, thereby affecting the conveying stability of the excavator track shoe.
