Description

Technical Field

[0003] The existing laying ship interlocking block lifting is completely dependent on manual experience: two operators operate two fully rotating cranes at the bow and stern to lift the concrete interlocking blocks. The lifting position, placement position and lifting process require the operator's weak eyesight to observe from a distance and multiple workers on site to remotely command the lifting through high-frequency and other communication tools. The personnel cost is relatively high, and the efficiency and safety are low.

The single cycle time from lifting the interlocking block - reaching the lifting position - returning to the lifting position takes 6 minutes. The lifting cycle time is long and the work efficiency is low. Therefore, a six-point truss concrete interlocking piece lifting device for a laying ship is proposed to address the above problems.

[0026] The utility model will be further described below in conjunction with the accompanying drawings.

[0027] like Figure 1-9 As shown, a six-point truss concrete interlocking piece lifting device for a laying ship includes a bracket assembly 1 and six sets of lifting assemblies 2; the six sets of lifting assemblies 2 are all slidably connected to the bracket assembly 1;

[0028] like Figure 1 , 2As shown, the bracket assembly 1 includes two main beams 11, each of which is connected to a main frame leg 12 at both ends, and two auxiliary beams 13 are connected between each left and right main frame legs 12; a longitudinal travel rack 14 is connected to the main beam 11, and the longitudinal travel gear is meshed with the longitudinal travel rack 14; a longitudinal travel roller groove 15 is opened on the main beam 11, and the longitudinal travel roller 442 is slidably connected in the longitudinal travel roller groove 15; a longitudinal travel limit roller groove 16 is opened on the main beam 11, and the longitudinal travel limit roller 443 is slidably connected in the longitudinal travel limit roller groove 16.

[0030] Specifically, the second rotating shaft 444 is driven to rotate by the longitudinal travel motor 446, and the rotation of the second rotating shaft 444 drives the connected longitudinal travel gear 445 to rotate, and the longitudinal travel gear 445 and the longitudinal travel rack 14 connected to the main beam 11 act to enable the longitudinal travel beam 41 to move on the main beam 11.

[0034] Specifically, the extension beam wire rope 464 is released by the winch 461, and the extension beam 451 is laid flat under the action of gravity, so that the transverse travel gear 32 can engage with the transverse travel extension rack 452, so that the transverse component 3 and the lifting component 21 can be moved to the extension beam 451 for lifting operations.

[0035] like Figure 5 As shown, the lifting assembly 2 includes a lifting assembly 21, and the lifting assembly 21 includes a wall panel bracket 211. The inner side of the wall panel bracket 211 is rotatably connected to the lifting drum 212.

When the lifting ring is hung on the hook, the lifting motor 213 rotates in the opposite direction to drive the lifting pulley block 215 to rise and drive the concrete chain piece to rise, and then the lifting component 21 moves backward to move the concrete chain piece to the appropriate position, and the lifting motor 213 releases the lifting wire rope 214 connected to the lifting drum 212 to make the lifting pulley block 215 descend and release the concrete chain piece; during the process, when the hook or the concrete chain piece has not reached the longitudinal target position, longitudinal movement is required, and the longitudinal travel motor drives the second rotating shaft to rotate, and the rotation of the second rotating shaft drives the connected longitudinal travel gear to rotate, and the longitudinal travel gear and the longitudinal travel rack 14 connected to the main beam 11 act to enable the longitudinal travel beam 41 to move on the main beam 11; through the above repeated movements, the purpose of quickly lifting the concrete chain piece can be achieved, and the six groups of lifting components 2 can move at the same time for lifting. The lifting process is simple and safe, and the labor intensity and labor cost of the operators are reduced to the maximum extent, which can effectively increase work efficiency.
