The sound, and chain drive is not suitable with positive and negative rotation transmitting power regime.Electric workover rig carries out needing tubing string when potential energy recycling
Drive winch, the transmission parts reverse rotation driving motor reversion power generation such as angle case, due to chain drive do not adapt to it is this it is frequent just
Operation Conditions are inverted, therefore are not suitable with the electric workover rig for having potential energy recycling function.In addition, chain transmission mode is logical
Crossing right angle gear box drives chain cover to carry out transmitting power, increases complete vehicle weight, workover rig vehicle is made not meet national standard
4.2 maximum design axle load limit values is related in GB1589 " automobile, trailer and truck combination contour dimension, axle load and quality limit value "
It is required that and then influence user's vehicle and settle, application places are limited.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of electric workover rig the shortcomings that overcoming the prior art, passed by gear
It is dynamic to replace chain conveyer, the components such as right angle gear box are eliminated, solves and is not adapted to frequently using chain drive progress potential energy recycling
Positive and negative rotation operating condition, can not pair potential the technical issues of can be carried out continuous conversion and recycling, structure is simple, alleviates vehicle design maximum
Gross mass.
To achieve the above objectives, the present invention adopts the following technical solutions: a kind of electric workover rig, including chassis, it drives
It sails and is provided with platen on the chassis at room rear, the platen front cross is equipped with generating set, the platen at generating set rear
Energy-storage module is installed on longitudinal centre line, is respectively arranged with braking resistor and control cabinet on the platen of energy-storage module two sides,
Variable-frequency motor and winch are horizontally arranged on the platen at rear, variable-frequency motor passes through the gear-box being arranged on the platen of one side and strand
Vehicle transmits power.
As a kind of improvement of the utility model, the energy-storage module is super capacitor group or battery.
As a kind of improvement of the utility model, the control cabinet includes the frequency converter for controlling variable-frequency motor revolving speed.
As a kind of improvement of the utility model, the power input shaft of the variable-frequency motor power output end and gear-box connects
It connects, the power output shaft of gear-box is connect with winch.
The utility model has the following beneficial effects: the utility model replaces chain conveyer by gear drive, right angle gear box is eliminated
Equal components, solve using chain drive carry out potential energy recycling do not adapt to frequent positive and negative rotation operating condition, can not pair potential can be carried out company
The technical issues of continuous conversion and recycling, structure is simple, alleviates vehicle maximum design total mass.In addition, the utility model system
Resistance is moved instead of traditional workover rig winch clutch, i.e., when drilling rod transfers progress potential energy recycling, under such as needing drilling rod slow
It puts, then its potential energy is recycled using energy-storage module, when drilling rod being needed quickly to transfer, then using braking resistor " digestion "
Its potential energy (falling the thermal energy consumption that the electric energy that variable-frequency motor inverts is converted into resistance), user can carry out phase according to actual needs
It should operate, structure is simple, easy to operate.
