Abstract
An upper accelerator oil injector for crane oil way exhausting comprises an oil tank and an oil injection pipe disposed on the top of the oil tank, wherein an oil injection pipe interface is disposed on the oil injection pipe; and the oil tank is also equipped with an oil addition pipe, and an air pressure check valve is disposed on the oil addition pipe. The upper accelerator oil injector for the crane oil way exhausting in the utility model has the simple structure, small volume, light weight and stable performances and can be manufactured easily. During use, certain volume of hydraulic oil is added to the oil tank from an oil addition hole, the oil addition hole is closed after addition, and the oil tank is kept sealed; an accelerator division pump oil hole is unscrewed and connected by an oil pipe, and the other end of the oil pipe is connected to the oil injector pipe interface; and an oxygen bottle is then connected to the oil addition pipe and hydraulic oil is poured and injected by air pressure until oil volume of the oil tank on the upper part of a crane reaches a standard oil level. The whole course can be completed by only one maintenance worker with a wrench, so that time and force are saved, air inside the oil pipe can be thoroughly evacuated for one time, maintenance time of equipment can be shortened, working efficiency is increased and labor strength of workers is reduced.
Description
Technical field
The utility model belongs to hoisting crane oil circuit repair apparatus technical field, particularly a kind of top throttle oiling machine for the exhaust of hoisting crane oil circuit.
Background technology
Development along with building and construction machinery and equipment, makes the market volume of miniature car hoisting crane very huge, and the maintenance rate of miniature car hoisting crane and maintenance load also increase thereupon simultaneously.Because the center of gyration sealing system of hoisting crane is fault point occurred frequently, when hoisting crane is used and keep in repair, can cause the throttle system coiling on hoisting crane to enter air, and the exhaust work of throttle system is required great effort very much, consuming time, waste material, neither one device can be once thoroughly by the Bas Discharged of pipeline inside.Conventionally the air-discharging way of taking is exactly: continuous servicing fluids force feed from the petrol storage tank of upper dish throttle first, trample continuously throttle master cylinder, make hydraulic oil pass through center steering oil circuit to throttle wheel cylinder, then the exhaust bolt on lower wall throttle wheel cylinder is opened and carried out exhaust work.Because the density of the density ratio hydraulic oil of air is much smaller, cause being difficult to the air in pipeline thoroughly to drain, and completing above-mentioned work generally needs at least 2 maintenance employees to spend that 1-3 days Time Continuous refuel repeatedly, the work of exhaust, not only waste time and energy, inefficiency, also waste a large amount of hydraulic oil simultaneously, to user, bring huge economic loss.
Utility model content
The purpose of this utility model is to provide a kind of simple in structure, the easy and simple to handle and top throttle oiling machine for the exhaust of hoisting crane oil circuit that can greatly increase work efficiency.
For achieving the above object, the technical solution of the utility model is: a kind of top throttle oiling machine for the exhaust of hoisting crane oil circuit, comprise the oiling tube that petrol storage tank and petrol storage tank top arrange, and oiling tube is provided with oiling tube interface; On petrol storage tank, be also provided with fuel filler pipe, fuel filler pipe is provided with air pressure check valve.
Described petrol storage tank top is provided with oil resistant air-pressure gauge.
Described oiling tube is provided with gate valve switch.
Described fuel filler pipe end is provided with oil filling port.
Compared with prior art, advantage of the present utility model is:
1, the utility model comprises the oiling tube that petrol storage tank and petrol storage tank top arrange, and oiling tube is provided with oiling tube interface; On petrol storage tank, be also provided with fuel filler pipe, fuel filler pipe is provided with air pressure check valve, and it is simple in structure, volume is little, lightweight, stable performance, is convenient to make, during use, first by oil filling port, to petrol storage tank, add a certain amount of hydraulic oil, after interpolation, close oil filling port, keep the sealing of petrol storage tank; Turn on throttle wheel cylinder hydraulic fluid port and connect with oil pipe, the oil pipe other end connects oiling tube interface; On fuel filler pipe, connect again oxygen bottle, utilizing air pressure to realize hydraulic oil falls to note, until the oil mass of hoisting crane top fuel accumulator reaches standard oil level, above-mentioned whole process only needs a service personnel to utilize a spanner just can operate, easy and simple to handle, time saving and energy saving, air in can the thorough emptying oil pipe of disposable realization, and can shorten the repair time of equipment, increase work efficiency, reduce workman's labour intensity.
When 2, oil resistant air-pressure gauge is convenient to oiling, observe the internal pressure of petrol storage tank.
3, on oiling tube, be provided with oiling tube interface, connecting line when easy to use; Meanwhile, on oiling tube, be provided with gate valve switch, be convenient to control the oil mass size of oiling.On fuel filler pipe, be provided with air pressure check valve, by increase air pressure in petrol storage tank, can conveniently realize hydraulic oil and fall to note.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
The top throttle oiling machine for the exhaust of hoisting crane oil circuit as shown in Figure 1, it comprises oiling tube 4, fuel filler pipe 2 and oil resistant air-pressure gauge 7 that petrol storage tank 1 and petrol storage tank 1 top arrange, petrol storage tank 1, for holding the needed hydraulic oil of top throttle system, is observed the internal pressure of petrol storage tank 1 when oil resistant air-pressure gauge 7 is convenient to oiling.On oiling tube 4, be provided with oiling tube interface 5, connecting line when easy to use; Meanwhile, on oiling tube 4, be provided with gate valve switch 6, be convenient to control the oil mass size of oiling.On fuel filler pipe 2, be provided with air pressure check valve 3, by the interior increase air pressure of petrol storage tank 1, realize hydraulic oil and fall to note.For the ease of to the interior oiling of petrol storage tank 1, in the end of fuel filler pipe 2, be provided with oil filling port 8.
In the present embodiment, the pressure of petrol storage tank 1 is 1Mpa, and the range of oil resistant air-pressure gauge 7 is 2Mpa, and gate valve switch 6 is carbon structural steel gate valve switch.
Principle of the present utility model is: the principle based on Pascal's law, the characteristic of utilizing gas to rise, promotes hydraulic oil with air pressure and fill with from bottom to top oil circuit, in oiling process, the gas in the middle of oil circuit is all discharged.
When the utility model is used, first, by oil filling port 8, to petrol storage tank 1, add a certain amount of hydraulic oil, after interpolation, close oil filling port 8, keep the sealing of petrol storage tank 1; Secondly, turn on throttle wheel cylinder hydraulic fluid port and connect with oil pipe, the oil pipe other end connects oiling tube interface 5; Then, on fuel filler pipe 2, connect oxygen bottle, utilize air pressure to realize hydraulic oil and fall to note, in the hydraulic oil process of falling note, can by gate valve switch 6, regulate the size of injection flows, until the oil mass of hoisting crane top fuel accumulator reaches standard oil level.Above-mentioned whole process only needs a service personnel to utilize a spanner just can operate, time saving and energy saving, can disposablely realize the air in emptying oil pipe.
