Description
Technical field
The invention belongs to a kind of detecting device, be specifically related to a kind of be applied to all types of crane hook drift angle detection or space to dangle the detecting device of object of which movement drift angle.It can realize the measurement of object pendulum angle and cireular frequency on xoz and yoz two projecting planes to the space object that dangles.
Background technology
The many technicians by having extraordinary professional qualification certificate of current weight-lifting equipment are engaged in operation.For improving the degree of automation of weight-lifting equipment, enhance productivity, liberation labour power, following hoisting crane can realize computer controlled automatic.Realizing in the process automatically controlled, be necessary link to the detection of suspension hook pendulum angle and cireular frequency.
Summary of the invention
The object of this invention is to provide a kind of telescopic suspension hook deviation angle detection device, its structure is simple, low cost of manufacture, reliability are high, check that precision is high and there is good practicality.
The present invention realizes like this, telescopic suspension hook deviation angle detection device, comprise supporting seat, supporting seat is fixedly mounted on cart base plate, supporting seat lower end is by x direction turning cylinder, x direction turning cylinder is fixedly connected with x-axis coder, coder joint piece is fixed on the turning cylinder of x direction, y direction turning cylinder is by coder joint piece, y direction turning cylinder is fixedly connected with y-axis coder and clump weight, location steel cable is through hollow Telescopic positioning lever, y direction turning cylinder is connected with Telescopic positioning lever, Telescopic positioning lever connects Telescopic positioning lever, Telescopic positioning lever connects Telescopic positioning lever, Telescopic positioning lever, steel rope is all connected with gib head movable pulley.
Described pulley connects gib head.
Advantage of the present invention is, utilize simple theory of machines can realize Telescopic positioning lever and the location angle orientation of steel cable in lifting process and suspension hook swing process, its structure be simple, motion flexibly, lifting freely, safe and reliable.In angle context of detection, utilize two detections being mutually coder realization object pendulum angle and cireular frequency on xoz and yoz two projecting planes at 90 degree of right angles dexterously.
Accompanying drawing explanation
Fig. 1 is the detection of object object pendulum angle and cireular frequency on xoz and yoz two projecting planes of dangling.

Fig. 3 is the left view of Fig. 2.
In figure: 1 supporting seat; 2 cart base plate; 3x direction turning cylinder; 4 steel ropes; 5y shaft encoder; 6x shaft encoder; 7 clump weights; 8y direction transmission shaft; 9 location steel cables; 10 Telescopic positioning levers, 11 Telescopic positioning levers, 12 Telescopic positioning levers; 13 gib head movable pulleys; 14 gib heads; 15 coder joint pieces.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in detail:
As shown in Figures 2 and 3, telescopic suspension hook deviation angle detection device comprises supporting seat 1, supporting seat 1 is fixedly mounted on cart base plate 2, supporting seat 1 lower end is by x direction turning cylinder 3, x direction turning cylinder 3 is fixedly connected with x-axis coder 6, coder joint piece 15 is fixed on the turning cylinder 3 in x direction, y direction transmission shaft 8 is by coder joint piece 15, y direction transmission shaft 8 is fixedly connected with y-axis coder 5 and clump weight 7, location steel cable 9 is through hollow Telescopic positioning lever 10, Telescopic positioning lever 11 and Telescopic positioning lever 12, y direction transmission shaft 8 is connected with Telescopic positioning lever 10, Telescopic positioning lever 10 connects Telescopic positioning lever 11, Telescopic positioning lever 11 connects Telescopic positioning lever 12, Telescopic positioning lever 12, steel rope 4 is all connected with gib head movable pulley 13, pulley 13 connects gib head 14.
1, suspension hook swing detection mode: be mutually 90 degree of coders installed mainly through two and realized.
2, steel cable and Multi-section telescopic radius stay is located in hook and decline process.
The present invention as shown in Figure 2.Because the suspension hook of hoisting crane or object swing in space of dangling may be any directions.In order to crane hook detected or dangle object swing drift angle and cireular frequency, the actual angle that can be swung by object according to accompanying drawing 1 decomposes on xoz and yoz two projecting planes.Namely decompose the projection angle obtained is the angle to be detected needed.
In order to reach above-mentioned testing goal, the utility model have employed ripe incremental encoder as detection means.Incremental encoder converts the angular transposition that turning cylinder produces to periodic electric signal, then this electric signal is transformed into count pulse, represents the device of the size of displacement by the number of pulse.By two incremental encoders are become 90 degree of installations, as shown in Figure 2, namely can reach detect suspension hook or dangle object of which movement time on xoz and yoz two projecting planes the object of angle and drift angle speed.
Because actual crane hook steel rope rigidity is not enough, in the design of detecting device, Multi-section telescopic radius stay and location steel cable are installed additional.Their effect, when ensureing that suspension hook swings on arbitrary height, all has enough rigidity, so that the drift angle detected exactly when suspension hook swings and drift angle speed.When crane lifting weight, pulley gib head does corresponding lifter motion, and gib head pushes expansion link upward movement.When hoisting crane transfers weight, expansion link is transferred under gravity piecemeal.Location steel cable does according to certain transmitting ratio and promotes accordingly and transfer motion simultaneously.
