Embodiment Construction

[0017] Such as figure 1 , figure 2 As shown, three groups of telescopic connecting rods 3 are distributed around the hydraulic cylinder 12 at a distance of 120° around the multi-stage single-rod double-acting multi-stage telescopic hydraulic cylinder 12. The connecting rods are fixed together on the load platform 1; the load platform 1 is mainly a connection platform for load parts. The upper support guide plate 4 and the lower support guide plate 2 are sleeved up and down on the hydraulic cylinder 12 and the telescopic connecting rod 3, and the upper support guide plate 4 and the lower support guide plate 2 play a supporting and guiding role. The lifting of the hydraulic cylinder 12 will drive the telescopic connecting rod 3 and the load platform 1 to lift together.

[0018] The upper part of the three sets of telescopic connecting rods 3 has a round table or a round table with ears main support platform 5, a round table or a round table with ears main support platform 5 i...

Abstract

The invention belongs to the metallurgical equipment field, especially relating to a hydraulic lift-turn mechanism. The invention is characterized in that three sets of expansion connecting rods (3) are arranged around a hydraulic cylinder (12) with the interval of 120 degrees. The terminational cylinder lever of the hydraulic cylinder (12) and the terminational connecting rod of the three sets ofexpansion connecting rods (3) are fixed on a load platform (1). An upper support guide board (4) and a lower support guide board (2) are arranged on the hydraulic cylinder (12) and the expansion connecting rods (3). The three sets of expansion connecting rods (3) have a main support platform (5) which is connected with the hydraulic cylinder (12) by a bearing (6). A hydraulic motor (9) is fixed by a bracket (11). The output shaft end of the hydraulic motor (9) is provided with a gear, a gear pair (10) and a limit ring (7) which is fixed on the hydraulic cylinder (12) by a binding bolt. The hydraulic motor (9) rotates the gear of the output shaft end to be meshed with the gear pair (10). The invention has the advantages of good reliability, easy maintenance and operation, high control precision, strong carrying capacity and broad application range.

Description

technical field [0001] The invention belongs to the field of metallurgical equipment, and in particular relates to a hydraulic lifting and turning mechanism which can not only perform lifting (linear) movement along the vertical Z-axis, but also perform forward and reverse rotation around the Z-axis. Background technique [0002] Mechanical lifting and turning devices are widely used in many occasions that require control of stroke and angular position. At present, the mechanical lifting and turning device is mainly composed of a screw nut or a worm gear and a gear mechanism. Its structure is complex, the failure rate is high, the installation space range is large, the carrying capacity is limited, and the control accuracy is low. Contents of the invention [0003] The object of the present invention is to provide a hydraulic lifting and turning mechanism, which has small installation space, good reliability, easy maintenance, easy operation, high control precision, stron...
