Auxiliary braking device for pumping unit anti-rolling with alarm function

Abstract

The invention relates to a pumping unit sliding prevention auxiliary brake device with an alarming function, which mainly overcomes the weaknesses that the existing auxiliary brake device is inconvenient to install and disassemble and does not have an alarming function. The pumping unit sliding prevention auxiliary brake device is characterized by consisting of two wedged single bodies which are identical in structure, wherein a main body of each single body is a wedged block which is made of a carbon steel material, and a plate supporting seat, a ring supporting seat, a hook ring and an elastic pressure plate are fixed on each wedged block; each wedged block is in a right-angled triangular shape, both a first right-angled edge end surface and an oblique-edge end surface of each wedged block are respectively a narrow-V-shaped toothed non-plane, and each second right-angled edge end surface extends inwards to form a first cavity; a sliding alarming mechanism consists of two alarming circuits, each of which is formed by connecting a buzzer, a sealing cover, a crown bar pin, a sealing ring, a spring, a crown bar pin guide frame, an upper trigger plate, a lower trigger plate and an insulation seat, and electric connection conducting wires which are respectively led from each upper trigger plate and the corresponding lower trigger plate are connected to a positive electrode and a negative electrode of a battery after passing through a coil of the corresponding buzzer to form a loop. The pumping unit sliding prevention auxiliary brake device is easy to install and has the alarming function.

Description

Technical field: [0001] The present invention relates to a safety device used on a beam pumping unit in an oil field, and in particular relates to a safety device that can prevent slippage when performing maintenance or parameter adjustment operations on a beam pumping unit. Auxiliary braking device with function and alarm function. Background technique: [0002] During the maintenance work of the beam pumping unit in the oil field, due to factors such as damage to the original brake device parts of the pumping unit, serious wear of the brake pads, dirty lubricating oil, and too light manual brakes, it is easy to cause oil pumping. The machine suddenly slipped, causing accidental injury to the maintenance workers. Therefore, in order to ensure that the failure of the original braking device of the pumping unit will not cause a slipping accident, it is necessary to add a secondary auxiliary braking device for safety protection when the oil pumping unit is being maintained or...

Problems solved by technology

However, after a long period of use, it has been found that the auxiliary brake devices of these pumping units have the following problems: the installation and removal of the auxiliary brake devices are relatively complicated, and connection parts such as bolts and bayonets need to be disassembled or installed. In addition, most When the equipment is installed, it is necessary to climb up to work, which brings certain safety hazards

Moreover, these auxiliary braking devices do not have an alarm function, and cannot remind the operators on the pumping unit and around them to avoid or take measures in time when the pumping unit just starts to slip.
