Abstract
The utility model relates to a weight box with a position-limiting device for an oil pumping machine. The weight box comprises a box body, wherein the box body is arranged between a vertical framework and a framework of the oil pumping machine, a belt lifting mechanism is connected at the upper part of the box body, the position-limiting device is further arranged on the weight box, the position-limiting device comprises stroke touch blocks arranged on the two sides of the weight box, stroke switches are arranged on the vertical framework of the oil pumping machine on the two sides of the weight box, the stroke touch blocks are positioned between the two stroke switches, and the stroke switches are connected with an automatic control system. The weight box disclosed by the utility model has the following advantages: once an emergency occurs, for example, upper and lower strokes of the oil pumping machine exceed the set limits, the stroke touch blocks can touch the two intermediate stroke switches, and the automatic control system receives signals and timely adjusts the motion state of the machine; and if an extreme abnormal situation occurs, the stroke touch blocks can touch two limit switches at the uppermost end or the lowermost end, and the automatic control system can timely brake and stop the machine and emit an alarm signal, thereby avoiding greater loss and playing a safety protection role.
Description
Technical field
The utility model has and relates to a kind of oil pumper, relates in particular to a kind of oil pumper that between ballast box and vertical frame, is provided with stopping means.
Background technology
Pumping current, including vertical frame, the upper part of the main frame with the upper platform, a lower portion of the platform, the upper platform or the platform is provided with a drive means on the platform is provided with setting wheel and the guide wheels, around the Over the guide wheel, over wheel, both ends of the belt driving device suspended on both sides of the main frame, the main frame side end portion of the belt connecting rod, the other side of the main frame connected to the counterweight end portion of the belt case, its assigned heavy boxes between the main frame is not set limit device, once the emergency situations, such as: pumping up and down stroke exceeds its set limit, by the workers to adjust the machine running visual, visual will be errors, if there is extreme anomalies , automatic brake control system Tong can not be shut down and an alarm signal, causing great loss....
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency a kind of oil pumper ballast box with stopper is provided.
The purpose of the utility model realizes through following technical scheme:
A kind of oil pumper ballast box with stopper comprises casing, and casing is arranged between the framework of oil pumper vertical frame; Casing top is connected with the belt hoisting mechanism; On ballast box, also be provided with stopping means, stopping means comprises the stroke collision block that is arranged on the ballast box both sides, and the oil pumper vertical frame of ballast box both sides is provided with travel switch; The stroke collision block is between two travel switches, and travel switch is connected with automatic control system.
Above-mentioned oil pumper ballast box with stopper is provided with limit switch on the oil pumper vertical frame of travel switch upper and lower, limit switch is connected with automatic control system.
Adopt technique scheme, the utility model has following advantage: the travel switch of this mechanism and limit switch are installed in the two ends up and down of vertical frame respectively, and the stroke collision block is fixed on the ballast box.Ballast box normally moves in the interval of two travel switches of centre through the belt hoisting mechanism but does not touch two travel switches; In case emergency case occurring exceeds it like: the upper and lower stroke of oil pumper and sets the limit; Two travel switches in the centre that the stroke collision block just can touch; The automatic control system acknowledge(ment) signal can timely adjustment machine running status, if extreme abnormal conditions stroke collision block will touch topmost or bottom two limit switches, automatic control system can also be sent alarm signal by timely brake application stoping; Avoid resulting in greater loss, play the safeguard protection effect.
