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

The head rope control apparatus
1. affiliated technical field
The present invention relates to a kind of control apparatus of multi-rope friction hoisting head rope length; Quick adjustment head rope length within the specific limits; The variable quantity of compensation head rope is implemented in double hook and promotes two lifting containers and carry out while operation, is a kind of head rope control apparatus that can effectively improve double hook lifting efficient.
2. technical background
At present; Multirope friction winder system (as shown in Figure 1) is the constantly elongation of head rope length in operational process, when being used for the double hook lifting, because head rope length constantly changes; The relative position of two lifting containers also changes thereupon, and two containers generally can not accurately arrive fixing job position simultaneously.Therefore, can not cause winding interval long the operation simultaneously of two containers (after generally being to accomplish the loading of a container, begin another container unloading again, or sequence of events) in contrast to this in the lifting process, influence promotes efficient.
3. summary of the invention
Promote the head rope length variations for solving many rope double hooks, cause and can not reduce the problem that promotes efficient in the operation simultaneously of two lifting containers, the present invention provides a kind of head rope control apparatus, quick adjustment length within the specific limits, the variable quantity of compensation head rope length.
The technical scheme that the present invention adopts is that adding head rope control apparatus (as shown in Figure 2) is realized the adjustment (being equivalent to regulate head rope length) of relative position between two lifting containers through the length of regulating the head rope control apparatus between lifting container and head rope suspension gear.
The principle of head rope control apparatus is to utilize gusset piece and switching-over joint etc. a plurality of (generally equating with the head rope number) YXZ type head rope tension balance device to be connected in parallel composition head rope control apparatus.The principle of single frame tension balance device is as shown in Figure 3, oil cylinder elongation when to the oil cylinder oiling of tension balance device, and the length of tension balance device (L) shortens thereupon, and when the injection flow of minimizing oil cylinder, the length of device (L) is extended thereupon.The head rope control apparatus principle that is composed in parallel by many tension balance devices is identical therewith; The length of device is by the injection flow decision of oil cylinder; Increasing oil cylinder injection flow device length then shortens; Reducing oil cylinder injection flow device length then increases, and realizes head rope length relative adjustment through the injection flow of regulating oil cylinder.
The invention has the beneficial effects as follows; The relative position of two lifting containers (being equivalent to regulate head rope length) in the quick adjusting multi-rope friction hoist system within the specific limits; Make two containers can rest in the loading and unloading position simultaneously; Be convenient to carry out the loading and unloading operation at two containers simultaneously, reduce the loading and unloading production time, improve lifting efficient.
4. the specific embodiment
Fit of the present invention is that installation switching-over joint is connected in parallel many tension balance devices with gusset piece then, and the oil cylinder of every tension balance device is connected in parallel with cross over pipe on every tension balance device (YXZ type) top.The bottom and the lifting container of tension balance device link, and the top of gusset piece and head rope suspension gear link (as shown in Figure 4), and switching-over joint part figure sees Fig. 5, and the gusset piece detail drawing is seen Fig. 6.
When adjusting the length of head rope control apparatus; Start gig control apparatus is stopped at the ingate place; With quick coupling its cross over pipe and external hydraulic station (Hydraulic Station that tension balance device is supporting) are linked, the injection flow that starts the Hydraulic Station setting device makes device length reach setting value.After untiing the connecting of cross over pipe and Hydraulic Station, elevator system is recovered normal operation.
