It puts and is set on bolster with closing device and is drivingly connected with pulley blocks；Pulley blocks then include top sheave and lower sheave, top sheave peace
Mounted in bolster bottom, lower sheave is set on immediately below top sheave and passes through central pin shaft to be connected with bucket valve.
Further, lifting device includes hoisting rope and pulling type sensor.
Further, closing device includes opening and closing rope and press type sensor.
Further, quantity >=2 of lower sheave.
Further, lifting device is drivingly connected top sheave and a lower sheave by hoisting rope, and closing device passes through
Opening and closing rope is drivingly connected another lower sheave and bucket valve.
The beneficial effects of the utility model are：(1) equipment design is simple, low manufacture cost, installs simplicity additional；(2) pull-type biography
Pulling force when sensor can show promotion on hoisting rope, so as to effectively prompt the safety whether current seized condition meets equipment will
It asks：(3) snap-in force of bucket valve and the snap-in force of crawl back bucket valve, can effectively prompt when press type sensor can show crawl
Whether current crawl situation is feasible, improves the reliability of equipment, makes operation safer；It (4), can by dynamic metering device
The variation of power, solves the problems, such as that conventional hoist cannot measure in cargo handling process during the use of monitoring grab bucket in real time；(5)
Dynamic metering device can be installed in various commercially available grab buckets, promote the performance of its grab bucket.
Description of the drawings
Attached drawing is used to provide a further understanding of the present invention, and a part for constitution instruction, with this practicality
Novel embodiment for explaining the utility model, does not form the limitation to the utility model together.In the accompanying drawings：
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
The preferred embodiment of the utility model is illustrated below in conjunction with attached drawing, it should be understood that described herein excellent
Embodiment is selected to be only used for describing and explaining the present invention, is not used to limit the utility model.
As shown in Figure 1, the utility model is related to a kind of grab bucket dynamic metering device, including bolster 1, strut 2, dynamic
Metrological service and bucket valve 7.Wherein, dynamic measuring mechanism is made of lifting device 3, closing device 4 and pulley blocks, and pulley blocks packet
Include top sheave 5 and lower sheave 6.
Strut 2 connects bolster 1 and bucket valve 7 by axis pin.While 2 connection structure of strut, to Supporting bucket valve
Movement.In the embodiment of the utility model, in order to improve the stability of equipment, altogether equipped with four struts 2, two bucket valves
7, strut 2 is connected to respectively by axis pin on four angles of the bolster 1 of cuboid-type, and two one group of connections, one bucket valve 7.Pin
Axis connection causes strut 2 to be free to rotate with the opening and closing of bucket valve 7 in a certain range.Meanwhile in order to increase stress
Point, the support force for making strut 2 is more balanced, and several trepannings 8 are uniform-distribution on strut 2.The presence of trepanning 8, on the one hand can
The stress of strut 2 is equably transferred to the position of solid rod, on the other hand, when bucket valve 7 is opened and closed, the center of gravity of total turns
It moves, trepanning 8 can strain gravity center shift, and rapid metastatic capacity effectively improves the safety of equipment, makes equipment more robust.
In order to make existing grabbing arrangement that can intuitively embody operation information in the process of running, added in grab bucket dynamic
State metrological service.Wherein, lifting device 3 and closing device 4 are set on bolster 1 and are drivingly connected with pulley blocks.And in pulley blocks,
Top sheave 5 is mounted on 1 bottom of bolster, and lower sheave 6 is set on immediately below top sheave 5, and passes through central pin shaft and be connected with bucket valve 7.
Pulley blocks are operated by lifting device 3 and the linkage whole device of closing device 4.
Lifting device 3 includes hoisting rope and pulling type sensor, and closing device 4 includes opening and closing rope and press type sensor.At this
In the embodiment of utility model, in order to meet the needs of promotion and opening and closing, there are two lower sheaves 6, and one is linked by hoisting rope
Top sheave 5, another is by being opened and closed linkage bucket valve 7 of restricting.In practical operation, pulley can also be increased as needed, met not
Same size, the equipment of weight.Hoisting rope generally volume is there are in lifting device 3, and when pulling type sensor can show use is promoted
Whether the pulling force on rope, the seized condition so as to prompt operator current meet the safety requirements of equipment, cause either with or without overweight
Pulling force overload on rope, generates security risk.And rope volume is opened and closed there are in closing device 4, opening and closing sensor can show crawl
When bucket valve snap-in force and capture back bucket valve snap-in force, the former can check whether equipment faulty before use, the latter
It can then judge whether current crawl situation is feasible, improves the reliability of equipment, makes operation safer, also solves when in use
The problem of conventional hoist cannot measure in cargo handling process.In addition, if the not vitiable cargo of processing, can also pass through pressure
Formula sensor, control opening and closing angle make the snap-in force of bucket valve while crawl needs are met, less than the endurance of cargo.
In addition, in order to increase the stability and high efficiency of grab bucket part, the bucket valve 7 of the utility model by opening and closing Supporting bucket and
Contact grab bucket is formed.Opening and closing Supporting bucket is connected with lower sheave by being opened and closed rope, and is contacted grab bucket and be fixed on out by axis pin
It closes below Supporting bucket, opening and closing Supporting bucket is merely responsible for being opened and closed, and contacts grab bucket to capture cargo, can effectively improve grab in this way
Struggle against whole stability, while increases contact grab bucket and open radian, improves crawl efficiency.
The utility model design is simple, in use, after installing dynamic measuring mechanism additional, lifting device 3 first receives operational order,
Hoisting rope is fallen, at the same time, closing device 4 also receives operational order, and opening and closing rope is rotated on a lower sheave 6, driven
Bucket valve 7 outwardly opens, and during operation, open angle can be adjusted voluntarily between 0 °~180 ° as needed.After capturing cargo, open
It closes rope to rotate backward, bucket valve 7 is made inwardly to be closed, finally tightly " bites " cargo.Hoisting rope is driven again, is risen bucket valve 7, is completed behaviour
Make.
The dynamic metering device of the utility model design can be installed in various commercially available idle grab buckets, promote its grab bucket
Performance.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, although ginseng
The utility model is described in detail according to previous embodiment, it for those skilled in the art, still can be with
It modifies to the technical solution recorded in foregoing embodiments or equivalent replacement is carried out to which part technical characteristic.It is all
Within the spirit and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in this practicality
Within novel protection domain.
