Description
Technical Field
The utility model relates to a mechanical gate technical field especially relates to be applied to screw headstock gear's measurement gate aperture device.
Background
As shown in fig. 1, a screw hoist in the prior art mainly comprises a motor 1, a gear box 2, and a screw 3, wherein the screw 3 is rigidly connected to a gate 4. The gate 4 of the sluice is opened and closed by the driving of the motor 1 and the rotation of the adjusting screw rod 3, so that the opening and closing functions are realized.
In order to visually represent the opening degree of the gate, a screw type opening and closing machine is generally provided with a gate height instrument. When the pump is started, water flow directly impacts a steel wire rope of the gate height instrument to trigger a displacement signal. However, the space for replacing the steel wire rope of the gate height instrument is narrow, maintenance personnel need to stand on the top of the gate, and the maintenance personnel are not only in near-water operation but also in high-altitude operation, and have poor maintenance working conditions and great potential safety hazards.
Therefore, how to overcome the defect of replacing the steel wire rope of the gate height instrument is a technical problem to be solved by technical personnel in the technical field.
SUMMERY OF THE UTILITY MODEL
In view of the above-mentioned defect of prior art, the technical purpose of the utility model is to provide a measurement gate aperture device that is applied to screw headstock gear that degree of automation is high, the security is good.
In order to achieve the technical purpose, the utility model provides a gate opening degree measuring device applied to a screw hoist, which is provided with a gear box and a screw; the screw is rigidly connected with the gate; a transmission rod is in transmission connection with a rotating shaft in the gear box; the transmission rod is in signal connection with the encoder; and an external digital display instrument receives the data signal of the encoder and displays the opening data of the gate.
The utility model has the advantages that:
the utility model discloses because above-mentioned structural design, through sensor, encoder, digital display appearance, with the automatic digital signal who turns into of gate aperture state, improved the measured degree of automation of gate aperture, reduced maintenance cycle, reduce cost of maintenance, improved equipment reliability.
Drawings
FIG. 1 is a schematic diagram of a prior art screw hoist;
fig. 2 is a schematic view of the transmission structure of the present invention.
Wherein, the gear box 2, the rotating shaft 21, the transmission rod 5, the encoder 6 and the digital display instrument 7
Detailed Description
The conception, the specific structure and the technical effects of the present invention will be further described with reference to the accompanying drawings, so as to fully understand the objects, the features and the effects of the present invention.
Example (b):
fig. 2 shows a device for measuring the gate opening degree applied to a screw hoist having a gear box 2 and a screw rigidly connected to a gate (not shown).
The motor drives the gear box, transmits the power to the screw rod, drives the gate to move up and down, and realizes the opening and closing functions of the gate.
The utility model discloses an improvement part lies in: a transmission rod 5 is arranged to be in transmission connection with a rotating shaft 21 in the gear box 2; by "drive connection" is meant that the angular displacement of the shaft 21 is correspondingly transmitted to the driving rod 5.
The transmission rod 5 is in signal connection with an encoder 6; the term "signal connection" here means that the stroke of the transmission rod 5 is converted into a pulse signal by the encoder 6, and the pulse signal is converted into data information.
In addition, an external digital display 7 receives the data signal of the encoder 6 and displays the opening data of the gate.
In some embodiments, the encoder 6 may adopt the following types: GAX60R13E10LB (9600) encoder
The working principle of the encoder is as follows: it is a rotary transducer that converts rotational displacement into a series of digital pulse signals that can be used to control angular displacement. The encoder can also be used to measure linear displacement when combined with a rack or screw.
Under normal working conditions, the gate has different opening degrees, and information of the opening degrees has a clear corresponding relation with the transmission of a screw rod of the screw rod type hoist and a certain rotating shaft 21 of the gear box 2. Through adding the transfer line, conduct the angle displacement of pivot 21 for encoder 6, form data signal and show through digital display instrument 7, the user just can know the aperture of gate directly perceivedly, no longer need change the wire rope of floodgate height appearance, just also eliminated the potential safety hazard.
The utility model discloses because above-mentioned structural design, through sensor, encoder, digital display appearance, with the automatic digital signal who turns into of gate aperture state, improved the measured degree of automation of gate aperture, reduced maintenance cycle, reduce cost of maintenance, improved equipment reliability.
The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the teachings of the present invention without undue experimentation. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
