Technical field
The utility model relates to a kind of device that changes, and is specifically related to a kind of compression spring and changes device, is adapted to the maintenance of auxiliary hoist handcart, belongs to the flight-line maintenance technical field.
Background technology
At present to pressure oil pump maintenance, find to make the compression spring of pressure arm return of piston rod and the go-cart of pressure oil pump that it is removed the therefore delay time of fixing a breakdown often of difficulty very, and influenced the progress of producing.
Summary of the invention
The purpose of the utility model invention is for overcoming the weak point of above-mentioned prior art; Provide a kind of compression spring to change device; This device includes two depression bars up and down, and an end of upperpush rod, down-pressed pole is connected with adjusting screw(rod), spherical washer, nut through bolt between two depression bars.According to craneman's go-cart to be keeped in repair; At first nut is threaded to the appropriate location; Make the bulb pawl contact vehicle body of down-pressed pole, two ends briquetting symmetry is pressed on the pad, the spinning nut makes the spring compression; Thereby dismountable last item, pinch roller and straight pin also can detect, keep in repair the decomposition of pressure oil pump.Otherwise during assembling mutually, through this device solves Time To Repair Part and installation difficulty, improved production and processing efficient, this device convenient mounting and clamping is easy and simple to handle in the maintenance process of go-cart.
The utility model is realized with following technical scheme: a kind of compression spring changes device; It is characterized in that: this device includes down-pressed pole, upperpush rod; One end of described upperpush rod, down-pressed pole passes through bolt; There is adjusting screw(rod) middle part at upperpush rod and down-pressed pole, and spherical washer on the adjusting screw(rod) has adjusting nut on the spherical washer; Fuselage, pad are arranged respectively between the other end of said upperpush rod, down-pressed pole, between fuselage and the pad plunges pump body is arranged, piston rod is arranged on the plunges pump body, there is compression spring at the two ends of plunges pump body; Between described down-pressed pole and the fuselage briquetting is arranged, fix through connecting pin; Between described upperpush rod and the pad briquetting is arranged, fix through connecting pin; Described down-pressed pole and piston rod are fixed through straight pin, also have pinch roller, wheel pressing shaft on the piston rod.
One end of described down-pressed pole and upperpush rod is the bulb claw shape.
Between described adjusting screw(rod) and the down-pressed pole positioning sleeve is arranged.
The utility model has the advantages that: this apparatus structure is simple, and craneman's go-cart to be keeped in repair at first is threaded to the appropriate location with nut; Make the bulb pawl contact vehicle body of down-pressed pole; Two ends briquetting symmetry is pressed on the pad, and the spinning nut makes the spring compression, thus removable removing; Last item, pinch roller and straight pin also can detect, keep in repair the decomposition of pressure oil pump.Otherwise during assembling mutually, through this device solves Time To Repair Part and installation difficulty, improved production efficiency, this device convenient mounting and clamping is easy and simple to handle in the maintenance process of go-cart.
