Abstract
The utility model provides a kind of improved moment limiting device, including mounting blocks, latch plate, travel switch, adjusting bolt, locking nut, it is characterised in that mounting blocks are connected by wired mode with safety control module box.The utility model can directly provide tower line warning message, easy to operate, safe and reliable.
Description
Technical field
The utility model relates generally to the safety monitoring technology field of engineering machinery, in particular to a kind of tower crane
Moment limiting device.
Background technology
With the development of construction industry, skyscraper is more and more, and tower crane is widely used as a kind of aerial lift device
To job site.But need starting and braking to complete the allocation and transportation work of weight in the position of centre of gravity height, the course of work due to tower crane,
So that the danger of tower crane in the course of the work is high compared with other crane gears.In addition, in tower crane work, constructor can not also examine
The change of the laterally horizontal degree of tower body and tower body axis is surveyed, if its change is excessive, the additional tilting moment of tower crane will be increased.When
The additional tilting moment of tower crane and the torque sum of load are just likely to cause tumbling for tower crane when being more than trimming moment.So will
Great accident is caused, operator and surrounding staff is in danger.At present, the limit applied on tower crane crane
Position device species is various, but most of control coefrficients are dull.In recent years, in the market is also occurred in that to the spacing of multiple coefficients control
Device, but there are many shortcomings, such as complicated, sensitivity is poor, and installation and debugging are numerous and diverse, so as to limit Multifunction position limiting
The further genralrlization application of device.
The content of the invention
For the defect of prior art, the utility model provides a kind of improved moment limiting device.
Target of the present utility model is to provide a kind of improved moment limiting device.
In order to solve the above technical problems, the utility model uses following technical scheme：
A kind of improved moment limiting device, including mounting blocks, latch plate, travel switch, adjusting bolt, locking nut,
Characterized in that, mounting blocks one end is sandwiched in the end of two pieces of latch plates, the other end passes through wired mode and safety control module
Box is connected, and travel switch is arranged on the centre position of two pieces of latch plates and is close to one end of adjusting bolt, adjusting bolt with
Locking nut is connected through a screw thread.
Further, safety control module box passes through wired connection with computer terminal display screen.
Further, safe block is iron block.
Limiter of moment travel switch and adjusting bolt etc. at two latch plates, three are constituted, and are fixed in by mounting blocks 1
On chord member on rear side of in the middle part of tower top, when tower crane works, tower top deforms, and the distance between two latch plates reduce, and drive and adjust
Whole screw rod movement, adjusting bolt touches travel switch.
Upward and the outside luffing of loading trolley the circuit of tower crane lifting can be alarmed and cut off to corresponding torque, play restraint
The protective effect of square.
The utility model gathers the parameter of monitoring tower crane using various types of data acquisition units in real time, and processor is to sensing
The tower crane parameter that device is collected is handled, and safety device monitoring system is according to result of the data acquisition unit to tower crane parameter processing
Carry out display alarm：When the signal of processing does not meet the numerical value of the system setting, safety device monitoring system display alarm,
And performing module is controlled.In order that driver observation is convenient, safety device monitoring system is installed on to the driver's cabin of tower crane
In.
Compared with prior art, the utility model has the advantage of：
1. original Multifunctional limiting device can not provide tower crane warning message, the utility model can provide tower crane alarm
Information.
2. can with Direct Recognition Multifunctional limiting device whether normal work.
3. simplifying monitoring flow, driver can directly read data information, easy to operate, safe and reliable.
4. improved limiter of moment, original limiter of moment is protected, can be by the reading of improved limiter of moment
Number, clearly knows the change of original limiter of moment.Tower crane is allowed more to insure in the process of running.
Brief description of the drawings
Fig. 1 is the structural representation in the utility model mounting blocks constitutional diagram concrete application example.
Fig. 2 is the utility model internal cross section figure.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings, but does not constitute to of the present utility model any
Limitation.
Embodiment 1
As shown in Figure 1 and Figure 2, a kind of improved moment limiting device, including mounting blocks 1, latch plate 2, travel switch 3, tune
Whole screw rod 4, locking nut 5, mounting blocks have two pieces, and two pieces of mounting blocks one end are sandwiched in the end of two pieces of latch plates, and the other end leads to
Cross wired mode with safety control module box to be connected, travel switch is close to one end of adjusting bolt, adjusting bolt and locking
Nut is connected through a screw thread.
Limiter of moment travel switch 3 and the grade of adjusting bolt 4 composition at two latch plates 2, three, it is solid by mounting blocks 1
It is connected on the chord member on rear side of in the middle part of tower top, when tower crane works, tower top deforms, the distance between two latch plates reduce, band
Dynamic adjusting bolt movement, adjusting bolt touches travel switch.
Upward and the outside luffing of loading trolley the circuit of tower crane lifting can be alarmed and cut off to corresponding torque, play restraint
The protective effect of square.
It the above is only preferred embodiment of the present utility model, protection domain of the present utility model is not limited merely to above-mentioned
Embodiment, all technical schemes belonged under the utility model thinking belong to protection domain of the present utility model.It should be pointed out that pair
For those skilled in the art, some improvements and modifications under the premise of the utility model principle is not departed from,
It should be regarded as protection domain of the present utility model.
