Problems solved by technology

[0003] In order to solve the problem that the length of the multi-rope double-hook hoisting head rope changes, resulting in the inability to work simultaneously in the two lifting containers and reducing the lifting efficiency, the invention provides a head rope adjustment device, which can quickly adjust the length within a certain range and compensate for the length of the head rope.

Embodiment Construction

[0007] The assembly method of the present invention is to install a reversing joint on the upper part of each tension balance device (YXZ type), then use a connecting plate to connect multiple tension balance devices in parallel, and connect the oil cylinders of each tension balance device in parallel with a connecting pipe together. The lower part of the tension balance device is connected with the lifting container, and the upper part of the connecting plate is connected with the first rope suspension device (such as Figure 4 shown), see the part diagram of the reversing joint Figure 5 , see the connecting plate parts diagram Figure 6 .

[0008] When adjusting the length of the head rope adjustment device, start the hoist to stop the adjustment device at the horse head door, connect the communication pipe with the external hydraulic station (the hydraulic station that is matched with the tension balance device) with a quick joint, and start the hydraulic station adjustm...

Abstract

A first rope adjusting device is used for adjusting the length of a first rope in a multi-rope friction hoisting system, and can rapidly adjust the length of the first rope in a certain range to compensate for the length change of the first rope. When a multi-rope friction hoisting machine is used for double-hook hoisting, two hoisting containers can not arrive at fixed loading / unloading positions at the same time in general due to the continuous extension of the first rope during the hoisting, so that loading / unloading operations can not be carried out in the two containers at the same time, which results in long loading / unloading time and low hoisting efficiency. In order to solve the above problem, the first rope adjusting device (shown in figure 1) is arranged between the hoisting containers and a first rope hanging device according to the technical scheme adopted by the invention; and the length change of the first rope can be compensated by adjusting the length of the device, which is equivalent to adjust the length of the first rope, so that the two hoisting containers can accurately arrive at the loading / unloading positions to carry out loading / unloading operations at the same time, thereby improving the hoisting efficiency.

Description

1. Technical field [0001] The invention relates to a multi-rope friction lifting head rope length adjusting device, which can quickly adjust the length of the head rope within a certain range, compensate the change of the head rope, and realize simultaneous operation in double-hook lifting and two lifting containers. Head rope adjustment device to improve double hook lifting efficiency. 2. Technical background [0002] At present, the multi-rope friction hoist system (such as figure 1 As shown) the length of the head rope will continue to elongate during the operation. When it is used for double hook lifting, because the length of the head rope is constantly changing, the relative position of the two lifting containers will also change accordingly. Generally, the two containers cannot reach the fixed working position accurately at the same time. . Therefore, during the lifting process, the two containers cannot be operated at the same time (generally after the loading of o...
