Abstract
The utility model discloses a detector used for detecting length and angle of a telescopic boom, which comprises a terminal box and a length detecting device and is characterized in that: a main shaft (10) of the terminal box is arranged on a bottom plate (5) through a shaft block 5; the length detecting device (1) is positioned on the other side of the bottom plate (5) and is driven and connected with the main shaft of the terminal box through a decelerating mechanism; the bottom plate (5) is provided with an angle detecting device (11). The utility model is a length and angle detector used for a telescopic boom, which has the advantages of simple and compact structure, being convenient for installation and debugging, low cost and high detecting precision.
Description
Technical field
The utility model relates to a kind of length, angle detector, particularly relates to a kind of collapsing length, angle detector that is used to detect the crane telescoping boom.
Background technology
Crane is the engineering machinery that is widely used in place handling goods such as building ground, goods yard harbour, material warehouse, in order to guarantee the security of its use, a kind of limiter of moment and suspension hook hoisting limiter has been installed on crane.
Limiter of moment mainly is the hoisting moment (that is: the product of hoisting weight and arm outreach) of restriction crane, overload when preventing the crane lift heavy is tumbled and the damage of structural member, and the suspension hook hoisting limiter then is to prevent that crampon pulleying and the collision of arm head from causing the accident.
Being used to transmit arm head pulleying signal at present gives the terminal box part of suspension hook hoisting limiter and is used to detect the length detection part that transmission hoisting arm expansion length signals is given limiter of moment, be used to detect the angular detection part that transmission arm luffing angle signal is given limiter of moment, these three groups of parts are installed in the diverse location on the crane telescoping boom respectively, this detector arrangement complexity, volume is bigger, trouble is installed, the production cost height, inconvenient debugging, profile are not attractive in appearance.
The utility model content
Technical problem to be solved in the utility model provides a kind of simple in structure, compact, easy for installation, production cost is low, debugging is convenient, accuracy of detection is high telescoping boom length, angle detector.
In order to solve the problems of the technologies described above, telescoping boom length, angle detector that the utility model provides, comprise terminal box and device for detecting length, the main shaft of described terminal box is installed on the base plate by bearing seat, described device for detecting length is installed in described base plate opposite side, and be connected with the spindle drive of described terminal box by reducing gear, on described base plate, angle detection device is installed.
Described reducing gear is for to be provided with duplicate gear on support, the meshed transmission gear on described duplicate gear and the described main shaft is installed in potentiometer on the described support gear with described duplicate gear engaged transmission is installed.
The case that covers described device for detecting length, angle detection device is installed on the described base plate.
Adopt telescoping boom length, the angle detector of technique scheme, the terminal box partial function of arm head pulleying signal and the length detection part of detection hoisting arm expansion length will be transmitted, the angular detection partial function that detects the arm luffing angle concentrates in together, and makes three groups of parts become as a whole.The utlity model has three kinds of functions, a kind of function is the collapsing length that is used to detect the crane telescoping boom, a kind of function is the luffing angle that is used to detect the crane telescoping boom, its detection signal is transported to limiter of moment and the supporting use of limiter of moment by cable, the third function is to carry the pulleying signal of arm head, with the supporting use of arm hoisting limiter.This compact conformation, volume is little, easy for installation, cost supports, and is requisite vitals on the crane.
In sum, the utility model is a kind of simple in structure, compact, easy for installation, production cost is low, debugging is convenient, accuracy of detection is high telescoping boom length, angle detector.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model structural representation;
Fig. 3 is a device for detecting length part-structure synoptic diagram.
Embodiment
Below in conjunction with embodiment the utility model is described in further detail.
Referring to accompanying drawing 1 and Fig. 2, this mechanism is made up of device for detecting length 1, conducting ring 2, case 3, bearing seat 4, base plate 5, backguy 6, leg 7, winding roll 8, coil spring box 9, main shaft 10, angle detection device 11.
Referring to Fig. 1, backguy 6 is wrapped on the cylindrical of winding roll 8, and backguy 6 input ends and telescoping boom head are fixed, and output terminal is fixed and passed main shaft 10 with winding roll 8 and is connected with conducting ring 2.When telescoping boom stretches out, drive backguy 6 and stretch out, and drive winding roll 8, main shaft 10, coil spring box 9 around bearing seat 4 rotations, current signal is passed to the suspension hook hoisting limiter by conducting ring 2 and output line.When telescoping boom was withdrawn, because the effect of coil spring box 9, winding roll 8 is return (when stretching out with arm opposite direction rotation) voluntarily, to reach that arm stretches out and all to play the effect of transmission signal when withdraw by backguy.
Referring to Fig. 3, when hoisting arm expansion drove main shaft 10 rotations, the gear parts on the main shaft 10 drove duplicate gear 101 rotations in the device for detecting length 1, again by duplicate gear 101 driven gears 102 and potentiometer 103 rotations.The potential value of potentiometer 103 rotation change is input to limiter of moment by output line and converts thereof into the hoisting arm expansion length value, thereby has played the function of hoisting arm expansion length detection.Duplicate gear 101, gear 102 and potentiometer 103 are installed on the support 104.
This kind telescoping boom length, angle detector can also carry out combining and configuring as required.If do not need to detect hoisting arm expansion length and angle, then can be with device for detecting length 1, angle detection device 11 dismountings are not adorned, and make this device just become single terminal box, only play the effect of transmitting the arm head signal.
