Abstract
A protecting device for inclination of an upright column comprises the upright column on which a stroke switch spacing protecting device and an upright column angle sensor are arranged. The stroke switch spacing protecting device is arranged at the lower end of the upright column. The upright column angle sensor is arranged on the upright column. The stroke switch spacing protecting device and the upright column angle sensor are respectively connected with a controller through a cable. Furthermore through triggering by at least one member in the stroke switch spacing protecting device and the upright column angle sensor, an adjusting signal is transmitted to the controller. The protecting device provided by the utility model performs good protecting function on the inclination of the upright column of a large-size piling machine and simultaneously has the advantages of convenient maintenance and simple operation. A terminal display device has reminding and alarming functions so that a manipulator can notice and process in time.
Description
Technical field
The utility model relates to a kind of protective device of column gradient.
Background technology
In the work of large-scale stake work machine, the requirement of column gradient is very high, particularly for column at more than 30 meters large-scale machines, the angle of inclination of column must guarantee within certain scope, otherwise the danger that complete machine topples can occur.So need us to grasp at any time column gradient, in operation, can find in time the situation that angle is excessive, and have the function of warning and automatic spacing.The limit method generally adopting at present has two kinds:
The first is that the numeral that the obliquity sensor of utilization measurement column angle is passed back judges and protects.This method is very high for the reliability requirement of obliquity sensor, if obliquity sensor itself goes wrong, or problem appearred in the circuit that it is connected with controller, all can cause angle abnormal, and limit function is lost.In fact, the malfunctioning regular generation of situation of this obliquity sensor;
The second is the limit method with travel switch.The method is arranged on limit switch tripod or column upper end mostly.This device circuit is long and be not easy protection, and limit switch is exposed to outside, is often subject to rainwater, dust, and hydraulic oil, butter etc. pollute and malfunctioning.And limit switch is contained in very high position, be difficult at ordinary times be checked through, in maintenance with also very inconvenient when changing.
The reliability of these two kinds of sides is not high, so in the column motion control of large-scale piling machinery, need one to be more reliably more conducive to the column angle guard method that detects and install.
Utility model content
The purpose of this utility model is to provide a kind of protective device of being convenient to detection and maintenance, column gradient that gradient protection reliability is high for the deficiencies in the prior art.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of protective device of column gradient; comprise column; travel switch limiting and protecting device and column angular transducer are installed on described column; described travel switch limiting and protecting device is arranged on the bottom of described column; described column angular transducer is installed on column; described travel switch limiting and protecting device is connected with controller by cable respectively with column angular transducer, and described travel switch limiting and protecting device and at least one triggering of column angular transducer send adjustment signal to controller.
Described travel switch limiting and protecting device comprises protection cylinder, baffle plate and travel switch; described protection cylinder diameter is greater than described column; described protection jacket casing is contained in the lower end of pillar; position on four sides of described column in described protection cylinder is provided with at least one travel switch; the position corresponding with travel switch described in each, described protection jacket casing inner side is provided with a baffle plate; between described travel switch and described baffle plate, be provided with certain distance; when described distance makes described column tilt to surpass security standpoint, travel switch will be touched baffle plate and trigger travel switch.
In sum; the utility model comprises travel switch limiting and protecting device and column angular transducer; thereby form mechanical position limitation and the spacing security standpoint that jointly guarantees column of the spacing double angle of program; and because travel switch limiting and protecting device is arranged on the bottom of column; thereby after travel switch limiting and protecting device damages, handled easily personnel change.Therefore the utility model plays a very good protection to the column gradient of large-scale stake work machine by duplicate protection, and maintenance is simultaneously convenient, simple to operate, has prompting and report to the police on terminal display, makes operator to find in time and to process.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the upward view of the utility model column.
The specific embodiment
Below in conjunction with accompanying drawing, further describe the specific embodiment of this patent.
As Fig. 1, shown in 2, a kind of protective device of column gradient, comprise column 1, travel switch limiting and protecting device and column angular transducer are installed on described column 1, described travel switch limiting and protecting device is arranged on the bottom of described column, described travel switch limiting and protecting device is connected with controller by cable respectively with column angular transducer, described travel switch limiting and protecting device comprises protection cylinder 3, baffle plate 5 and travel switch 4, described protection cylinder 3 diameters are greater than described column 1, a columniform protection cylinder 3 is installed in column 1 bottom, in four sides of column 1, protecting the position in cylinder 3 that dismountable travel switch is installed respectively, make X-axis and the Y direction of a plurality of travel switches in horizontal plane, on the position corresponding with described travel switch 4, protection cylinder 3 inner sides, baffle plate 5 is installed, the position corresponding with travel switch described in each, described protection jacket casing inner side is provided with a baffle plate 5, between described travel switch 4 and described baffle plate 5, be provided with certain distance, when described distance makes described column tilt to surpass security standpoint, travel switch will be touched baffle plate and trigger travel switch.
Operating principle of the present utility model is: the movement of column 1 is divided into the action of X axis and Y-axis.Utilize column angular transducer 2 to gather the gradient signal of column 1, transmit into controller, when column 1 moves to the spacing angle of regulation toward a direction, controller sends alarm signal, and showing the spacing direction of screen display, the action that simultaneously limits column 1 can only be toward the direction action of spacing opposite direction.Again by the travel switch 4 in column 1 bottom, when column 1 angular deflection is when excessive, can trigger travel switch 4, travel switch 4 passes the signal to controller, can on display screen, report to the police and limit the action of column equally, make like this no matter be column angular transducer 2 or travel switch 4 can be by sending the action of signal limitations column to controller, thereby no matter be that part infringement, another one can be complete play a role, in practical operation, according to the sensitivity of column angular transducer 2 and travel switch 4, general travel switch 4 trigger angle are slightly less than column angular transducer 2, make like this to adjust more accurate.In addition, in order to guarantee the safety of protection cylinder after travel switch 4 damages, by the signal framing open type of travel switch 4, when triggering or damaging, be all 0V voltage.
