Abstract
A pumping unit electric brake mechanism comprises an upper connection rod, a lower connection rod, a linear motor and a controller. The pumping unit electric brake mechanism is characterized in that internal threads are arranged at the left end of the upper connection rod and the left end of the lower connection rod, the upper connection rod and the lower connection rod are connected with an upper pull rod and a lower pull rod of an original brake system through the internal threads, the linear motor is fixed on a supporting plate through locking nuts, a round hole is formed in the upper portion of the supporting plate, the left end of the upper pull rod penetrates through the round hole in the supporting plate and is connected with the supporting plate in an inserted mode, and the left end of the lower connection rod penetrates out of the supporting plate and is fixed on the supporting plate through set nuts. The controller is arranged in a pumping unit circuit control cabinet through a cable. The pumping unit electric brake mechanism has the advantages of being convenient to install, simple in structure, reliable in operation, and the like. In addition, the pumping unit electric brake mechanism lightens labor intensity and improves work efficiency and reliability.
Description
Technical field
The utility model relates to a kind of pumping unit, especially a kind of pumping unit electric brake mechanism.
Background technique
Existing oil pumping unit brake system is comprised of brake lever, transverse and longitudinal pull bar, brake shoes etc., and the size of the power by manually being applied to brake lever determines braking effect and intensity.This system has determined when brake operation, the operator must apply enough power, the guarantee pumping unit stops at specified position, and keep absolute halted state, overcome because bearing strength test changes the braking strength that causes and weaken, cause brake failure to cause manufacturing mechanism to damage and jeopardize workmen's life safety.This brake system is had relatively high expectations to operator's physical efficiency simultaneously, is badly in need of Improvement and perfection.
The model utility content
The purpose of this utility model is deficiency and the defective that exists for existing oil pumping unit brake system, a kind of pumping unit electric brake mechanism is provided, be applicable to use in pumping unit that pumping unit mechanical brake system adopts hem type duplex pull rod operating device, install on the structure of former mechanical brake, control unit is arranged in the circuit control box of pumping unit, and installation, convenient disassembly have reduced personnel labor intensity, guarantee reliability and the Security of brake, improved working efficiency.
The technological scheme that adopts is:
A kind of pumping unit electric brake is by upper connecting rod, lower link, linear electric motor and controller, the left end that it is characterized in that described upper connecting rod and lower link has internal thread, upper connecting rod is connected internal thread and is connected with the upper and lower pull bar of former brake system with lower link, linear electric motor are fixed on a dunnage by locking nut, the top of dunnage has a circular hole, circular hole and dunnage that the left end of upper connecting rod passes on dunnage are pegged graft, the lower link left end passes dunnage, and is fixed on dunnage by set screw nut.Controller is arranged in the pumping unit circuit control box by cable.
The utlity model has the advantages such as easy for installation, simple in structure, that operation is reliable.The utility model has alleviated labor intensity, has improved working efficiency and reliability.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
A kind of pumping unit electric brake comprises connecting rod 1, lower link 2, linear electric motor 3 and controller 6.The left end of upper connecting rod 1 and lower link 2 has internal thread, bar 1 is connected with lower link and is connected with the upper and lower pull bar of former brake system by internal thread, linear electric motor 3 are fixed on a dunnage 4 by locking nut 7, the top of dunnage 4 has a circular hole, circular hole and dunnage 4 that the left end of upper connecting rod 1 passes on dunnage 4 are pegged graft, lower link 2 left ends pass dunnage 4, and are fixed on dunnage 4 by set screw nut.Controller 6 is arranged in the pumping unit circuit control box by cable 5, when linear electric motor 3 work, motor shaft is moving linearly forward, the push rod that is connected with axle withstands a brake shoes simultaneously, form cohesive force at the drop-down another shoe plate of the effect of lower link 2 reaction forces, realize band-type brake, and can realize that machinery is locked, prevent the slipping of brake phenomenon, during releasing of brake, programmed sequence of operations is opposite.Control power acquisition with 24 volt-amperes of full voltages.
