Detailed Description

The present invention is described in further detail below with reference to figures 1 and 2.

A digital intelligent tensioner for a belt of an oil pumping unit comprises a contact monitoring part 1, a signal transmission part 2, a lifting part 3 and a control module 4, wherein the contact monitoring part 1 is used for monitoring the tightness of the belt, the signal transmission part 2 is used for transmitting a signal monitored by the contact monitoring part 1 to the control module 4, and the lifting part 3 is used for adjusting the tightness of the belt; wherein, contact control portion 1 includes load sensor 1.1, and signal transmission portion 2 includes RS485 module 2.1, and lift portion 3 includes motor 3.1, 3.2 with the lift of motor 3.1 coupling.

The tightness control device adopted for controlling the belt in the beam pumping unit in the prior art is generally a single structure and cannot realize timely and accurate operation under different working conditions, so that the working progress is influenced. The invention realizes certain control and monitoring purposes in an intelligent control mode, and is specifically divided into the following states:

1) when the contact monitoring part 1 monitors that the load is reduced or increased, the looseness of the belt is judged, a signal is sent to the control module 4 for intelligent amount judgment, then the control module 4 acts on the lifting part 3, the lifting part 3 is used for ascending or descending, the purpose of adjusting the reasonable tightness of the belt is achieved, and finally the load data is transmitted to the station control center through the signal transmission part 2;

2) when monitoring load and being 0, judging that the belt has taken place the fracture, contact monitoring portion 1 can in time transmit data to the station accuse center through digital signal transmission portion 2 this moment, reminds the user to change.

Therefore, the tightness of the belt is judged by monitoring the load of the belt, so that the purposes of adjusting the tightness of the belt in time, saving the belt, saving labor force and reducing risk hidden dangers are achieved, and the probability of stopping the well and stopping production is reduced.

Load sensor 1.1 locates on the bearing surface of belt, and control module 4 includes a singlechip 4.1 or remote client, and remote client includes a display screen that can look over belt tension.

In-process at the elasticity that utilizes this device to monitor the belt, utilize load cell 1.1 to carry out the monitoring of belt elasticity, then pass through signal conductor with the signal of monitoring and carry out teletransmission to divide into two kinds: when the load value is 0, the load value is directly transmitted to a station control center to remind a user of replacing a new belt; when the load value is suddenly increased or reduced, the motor 3.1 drives the lifter 3.2 to work through the relay 5 and the contactor 6 which are connected in series, and the purpose of adjusting the tightness of the belt is achieved.
