Description
Technical field
The application is related to a kind of derrick crane, more particularly to a kind of anti-error overload protecting system of derrick crane.
Background technology
Existing derrick crane is in carry arm hoisting heavy, if weight imprudence catches on ground weight, in carry arm mistake
Cheng Zhong, although carry arm effect can reduce derrick crane Moment, but weight is when catching on ground weight, and weight is often
Increased more, i.e., the torque that derrick crane is born is increase in fact, but derrick crane often lacks protection system
System so that torque exceedes after derrick crane tolerance range, occurs major accident.
Utility model content
The purpose of this utility model is to provide a kind of derrick crane anti-error overload protecting system, to overcome prior art
In deficiency.
To achieve the above object, the utility model provides following technical scheme：
The embodiment of the present application discloses a kind of anti-error overload protecting system of derrick crane, including：
Large arm, length is R；
Suspension hook；
Lifting rope, in suspension hook described in the large arm top suspension；
Hoist engine, connects the lifting rope；
Angular transducer, measures the angle α of the large arm and horizontal direction and is transmitted to control system in real time；
Gravity sensor, measures the bearing capacity G of the lifting rope and is transmitted to control system in real time；
Control system, controls the lifting and landing of the large arm, receives the angle α and bearing capacity G, calculates in real time tower
Crane bears torque M=G*R*cos α, and the control system is preset with maximum moment value Mmax, as M ＞ 105%MmaxWhen, institute
Stating control system forbids the large arm to land；As M >=125%MmaxWhen, the hoist engine discharges the lifting rope.
It is preferred that, in the above-mentioned anti-error overload protecting system of derrick crane, the set-up of control system has maximum to hold
Carry force value Gmax, as the bearing capacity G ＞ GmaxWhen, the hoist engine discharges the lifting rope.
It is furthermore preferred that in the above-mentioned anti-error overload protecting system of derrick crane, in addition to prior-warning device, as the M
＞ 90%MmaxOr G ＞ 90%GmaxWhen, the control system control prior-warning device alarm.
It is furthermore preferred that in the above-mentioned anti-error overload protecting system of derrick crane, the prior-warning device is buzzer.
It is furthermore preferred that in the above-mentioned anti-error overload protecting system of derrick crane, the control system also includes display
Device, shows the M values, M in real timemaxValue, G values, GmaxValue, the MmaxDifference, the G between M valuesmaxThe difference between G values.
It is furthermore preferred that in the above-mentioned anti-error overload protecting system of derrick crane, the large arm is scalable large arm, institute
State large arm and position sensor is set, big arm lengths R values are measured in real time and control system is transmitted to.
The embodiment of the present application also discloses a kind of derrick crane, including the above-mentioned anti-error overload protection system of derrick crane
System.
Compared with prior art, advantage of the present utility model is：During tower-type crane operation, real-time monitoring tower
The torque that formula crane is born, if when torque is more than 105%MmaxWhen, derrick crane can realize that carry arm is operated, because
When weight weight does not increase, carry arm operation can reduce torque, can protect derrick crane, but can not fall arm operation, fall
Arm operation can increase torque, and derrick crane is possible to damage；But as torque >=125%MmaxWhen, illustrate that weight is possible to
Tangle ground article, continue carry arm not but not reduce torque, it is possible to torque can be continued to increase, this will damage tower
Heavy-duty machine, at this time can only just discharge weight protection derrick crane, realize the effect of protection derrick crane.
Brief description of the drawings
, below will be to embodiment or existing in order to illustrate more clearly of the embodiment of the present application or technical scheme of the prior art
There is the accompanying drawing used required in technology description to be briefly described, it should be apparent that, drawings in the following description are only this
Some embodiments described in application, for those of ordinary skill in the art, on the premise of not paying creative work,
Other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 show the anti-error overload protecting system logical schematic of derrick crane in the utility model specific embodiment.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Detailed description, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole implementation
Example.Based on the embodiment in the utility model, those of ordinary skill in the art institute on the premise of creative work is not made
The every other embodiment obtained, belongs to the scope of the utility model protection.
With reference to shown in Fig. 1, the anti-error overload protecting system of derrick crane, including：
Position sensor, measures scalable big arm lengths R values and is transmitted to control system in real time；
Angular transducer, measures the angle α of large arm and horizontal direction and is transmitted to control system in real time；
Gravity sensor, measures the bearing capacity G of lifting rope and is transmitted to control system in real time；
Control system, receives big arm lengths R values, angle α and bearing capacity G, and derrick crane is calculated in real time and bears torque M=
G*R*cosα；
Display device, shows M values, default maximum moment M in real timemaxValue, G values, default maximum load capacity GmaxValue, MmaxWith M
Difference, G between valuemaxThe difference between G values；
Hoist engine, connects lifting rope；
Lifting rope, in large arm top suspension suspension hook；
Suspension hook, as M ＞ 105%MmaxWhen, control system forbids large arm to land；As M >=125%MmaxOr G values>GmaxWhen,
Hoist engine discharges lifting rope；
Prior-warning device, as M ＞ 90%MmaxOr G ＞ 90%GmaxWhen, prior-warning device alarm, prior-warning device is buzzer.
When in tower-type crane operation, the torque that derrick crane is born is monitored in real time, if when torque is more than 105%
MmaxWhen, derrick crane can realize that carry arm is operated, because when weight weight does not increase, carry arm operation can reduce torque, can
To protect derrick crane, but arm operation can not be fallen, torque can be increased by falling arm operation, and derrick crane is possible to damage；
But as torque >=125%MmaxWhen, illustrate that weight is possible to tangle ground article, continue carry arm not but not reduce torque,
It is possible to that torque can be continued to increase, this will damage derrick crane, at this time can only just discharges weight protection derrick crane,
Realize the effect of protection derrick crane.
