In specific practice, the problem of rigid collision between the inner cylinder and the face cover member caused by too high driving force of the driving member can be prevented by matching the buffer guide member and the anti-abrasion guide sleeve. The outer circular surface of the buffer guide sleeve is convexly provided with a reinforcing rib for improving the rigidity of the buffer guide sleeve; preferably, the direction of arrangement of the reinforcing ribs is along the length direction of the inner cylinder.
Further, in order to fully utilize the material cushioning characteristics of the wear-resistant guide sleeve 123 and the buffer guide sleeve 1321, in this embodiment, the projection line of the inner ring of the wear-resistant guide sleeve 123 on the buffer guide sleeve 1321 is located between the inner ring line and the outer ring line of the buffer guide sleeve 1321, that is, the two lines are in an end-face overlapping contact relationship along the axis direction, rather than a nesting relationship, so that the cushioning performance of the lifting ground column can be further improved.
Further, the mounting plate 122 is provided with a number of contact sensors 124 equal to the number of the guide posts 121, and the guide ring plate 131 is provided with a notch for avoiding the contact sensors 124. In specific practice, when the inner cylinder descends, the contact sensor passes through the guide ring plate through the notch, and if the contact sensor touches the heightening ring plate, the contact sensor feeds back to the controller so that the controller controls the driving piece to stop working, and the inner cylinder is positioned in the embedded outer cylinder. Further, a number of raised glue posts 133 equal to the number of the guide posts 121 are provided between the raised ring plate 1322 and the guide ring plate 131, and the raised glue posts 133 are mounted on the guide ring plate 131. In specific practice, the height of the buffer guide sleeve relative to the guide ring plate can be adjusted by replacing the heightening rubber column, that is, when the driving force of the driving piece is too low, the position of the driving inner cylinder reaching the highest point is not in accordance with actual requirements, and the height of the buffer guide sleeve relative to the guide ring plate can be adjusted by replacing the thinner heightening rubber column, so that the travel of the inner cylinder is shortened, and the defect of insufficient lifting height of the inner cylinder caused by too low driving force is overcome. Therefore, the problem of insufficient lifting height of the inner cylinder caused by too low driving force of the driving piece can be prevented through the combined use of the buffer guide piece, the guide ring plate and the heightening rubber column, and the technical defect caused by unstable driving force is effectively avoided.
To sum up, in this embodiment, through the radial spacing direction of interference fit inner tube bottom the guide ring plate at the guide post to and the inner tube is passed through the radial spacing direction of abrasionproof guide sleeve under the combined action of the face lid in the lifting motion process under the driving piece drive, prevents that the inner tube from going up and down the in-process from rocking, effectively ensures the motion stability of inner tube in-process that goes up and down. Moreover, the problem of rigid collision between the inner cylinder and the surface cover member caused by overhigh driving force of the driving member can be prevented by matching the buffer guide member and the anti-abrasion guide sleeve; in addition, through the combined use of the buffer guide piece, the guide ring plate and the heightening rubber column, the problem of insufficient jacking height of the inner cylinder caused by too low driving force of the driving piece can be prevented, and the technical defect caused by unstable driving force is effectively avoided.
