Technical Field

[0001] The invention relates to a heavy-duty truss robot with a rigid lifting shaft. Background Art

[0002] Traditional lifting equipment generally uses steel wire ropes or cables to directly lift the workpiece, moves it to the designated position by a crane, and then drops the workpiece. In this process, since the steel wire ropes or cables are flexible parts, the workpiece is prone to shaking during the lifting process, and manual support is required to keep the workpiece stable during the lifting process. In this lifting method, the shaking of the workpiece can easily pose a safety hazard to surrounding objects or personnel. Even during the manual support process, there is a risk of the workpiece hitting a person or object due to its excessive inertia. Summary of the invention

DETAILED DESCRIPTION

[0015] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0016] like Figure 1 to Figure 3A heavy-duty truss robot with a rigid lifting axle is shown, which has a pair of trusses 1 arranged at a distance from each other and supported by columns. The truss 1 is provided with a transverse track 9, and a large frame 2 is provided on the transverse track 9 to move transversely along the truss 1. Large wheels 10 that roll with the transverse track 9 are installed at the four corners of the large frame 2, and a transverse motor 11 that drives the large wheel 10 at the corner end is installed at a corner end of the large frame 2. A longitudinal track 12 is provided on the large frame 2, and a small frame 3 that moves longitudinally along the large frame 2 is provided on the longitudinal track 12. Small wheels 13 that roll with the longitudinal track 12 are installed at the four corners of the small frame 3, and a longitudinal motor 14 that drives the small wheel 13 at the corner end is installed at a corner end of the small frame 3.

[0017] A rectangular fixed bracket 4 is fixedly connected to the trolley frame 3, and the fixed bracket 4 has four rectangularly distributed vertical rods. A cross bar is fixedly connected to the bottom between the front two vertical rods and the bottom between the rear two vertical rods respectively. Roller support plates 25 are fixed above and below the outer sides of each vertical rod respectively. A roller 15 arranged inward is installed on each roller support plate 25, and two intervally distributed fixed plates 24 are fixed on each cross bar.

[0018] A lifting frame 5 is rollingly arranged in an inner frame surrounded by four vertical bars of the fixed bracket 4. The lifting frame 5 has four lifting rods 26 made of I-beams. An outer raceway 16 is formed on the outer side of the lifting rods 26, and an inner raceway 17 is formed on the inner side of the lifting rods 26. The roller 15 of the fixed bracket 4 rolls with the outer raceway 16; support cross bars are fixed to the upper end and the middle part between the sides of the two lifting rods 26 respectively, and a connecting column 27 is fixedly connected between the two supporting cross bars located at the upper ends of the lifting rods 26. Inner pulley blocks 22 corresponding to the fixed plate 24 are installed at intervals on the connecting column 27; outer pulley blocks 21 are installed on the two supporting cross bars located in the middle of the lifting rods 26 respectively.

[0019] A lifting frame 6 is provided on the inner side of the four lifting rods 26 of the lifting frame 5, and a guide wheel 18 is installed on the outer side of the lifting frame 6 to roll with the inner raceway 17 of the lifting frame 5. Fixed seats corresponding to the positions of the inner pulley blocks 22 are fixed at intervals on the cross bracing bars of the lifting frame 6.

[0020] The lower end of the lifting rack 6 is fixedly connected with a material storage frame 7 for storing materials.

[0021] The trolley frame 3 is provided with two sets of traction devices arranged on the left and right, and the traction device includes a traction motor 19 installed on the trolley frame 3, a lifting drum 8 driven by the traction motor 19, and a main steel wire rope 20 wound around the lifting drum 8. The main steel wire rope 20 is connected to the pulley of the outer pulley group 21 to lift the lifting frame 5, and an auxiliary steel wire rope 23 is passed around the pulley of the inner pulley group 22. The upper end of the auxiliary steel wire rope 23 is connected to the fixed plate 24, and the lower end of the auxiliary steel wire rope 23 is connected to the lifting frame 6.

[0022] During lifting, the lifting drum 8 driven by the traction motor 19 moves, and by utilizing the rolling cooperation between the outer raceway 16 and the roller 15 of the lifting frame 5, the main steel wire rope 20 pulls the lifting frame 5 up through the pulley block 21. Since the upper end of the auxiliary steel wire rope 23 is fixed to the fixed plate 24, when the lifting frame 5 rises, the upper end of the auxiliary steel wire rope 23 that passes over the pulley of the inner pulley block 22 is stretched, which makes the lower end of the auxiliary steel wire rope 23 connected to the lifting frame 6 pulled up, and the lifting frame 6 is lifted through the rolling cooperation between the guide wheel 18 on the outer side of the lifting frame 6 and the inner raceway 17 of the lifting frame 5, and finally the lifting of the material storage frame 7 is realized, and it moves into place with the large frame 2 and the small frame 3, and the traction motor 19 reverses to lower the material storage frame 7, completing the heavy object handling process.

[0023] In the present invention, since the lifting frame 5 is made of I-beam to form a rigid lifting shaft structure, during the process of lifting and transporting large workpieces, the vertical lifting of the lifting frame 5 will not shake, thereby maintaining the stability of the workpiece during lifting, preventing safety hazards to surrounding objects or personnel caused by the shaking of the workpiece during traditional wire rope lifting, thereby improving operation safety.

[0024] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
