Abstract
The utility model discloses a leakage detection device for an oil tank of an excavating machine. The device includes a water tank, a compressed air pipeline and a gas source, and is characterized by further including a weight-gaining device, wherein the weight-gaining device comprises a permanent magnet and a balancing weight; and the balancing weight is suspended and welded onto a connecting bar of the permanent magnet and locked with the permanent magnet through a nut. The weight-gaining device is absorbed on a side plate of a tank body of the oil tank when the leakage detection for the oil tank of the excavating machine is carried out; the space on the upper side of the water tank is obstacle-free for the reason that a thrust supplying device on the upper side of the leakage detection water tank is dispensed, so that the oil tank can be put in and taken out conveniently; and the oil tank can be flexibly overturned in water after being immersed in water, so that all the weld joints on any surface can be observed flexibly, and the detection efficiency is improved.
Description
Technical field
The utility model relates to a kind of device that fuel tank leaks hunting that detects, and is specifically related to a kind of excavator fuel tank pick-up unit that leaks hunting.
Background technology
At present, need after hydraulic reservoir of using on the excavator and fuel tank assembly welding are finished each weld seam is carried out
The detection of sealing, in the fuel tank whole immersion in each installation opening sealing back (wherein having an installation opening to be connected into pressurized air) water, fuel tank internal is charged into the pressurized air of certain pressure, and keep constant voltage, observe each commissure whether have bubble to overflow, whether qualified to judge the fuel tank sealing.Volume of fuel tank is relatively large, after putting into tank, because buoyancy function floats on the water surface a big chunk of fuel tank, in order to guarantee that fuel tank can wholely immerse in the water, the tank upside that leaks hunting of being everlasting is installed a cylinder, by cylinder rod fuel tank is applied a downward thrust, fuel tank integral body is pushed below the water surface.This type of device adopts this device can finish the testing of excavator fuel tank sealing as shown in Figure 1, but has following shortcoming: (1) acting surface of thrust downwards is necessary for the plane, could guarantee that fuel tank steadily is pressed into the water surface; (2) because fuel tank is in by application of force state always, can not be in water rotation flexibly, so can know above having only and observe the gas leakage position, other face position that leaks gas also need forward fuel tank to corresponding surface and is pressed into up in the water, complex operation, work efficiency is lower; (3) because the thrust feedway on the fuel tank is placed on directly over the tank, is not easy to putting into and taking out of fuel tank, and has fuel tank and the hidden danger of colliding with between it; (4) provide the cylinder of thrust need connect compressed air piping and the gauge tap of controlling the push rod stroke, structure is comparatively complicated, and the meeting consumption of compressed air, is difficult for the interior constant voltage of assurance fuel tank.Therefore, the traditional excavator fuel tank pick-up unit that leaks hunting can not satisfy the requirement that fuel tank acts freely, the efficient detection fuel tank leaks hunting.
Summary of the invention
Goal of the invention of the present utility model provides a kind of excavator fuel tank pick-up unit that leaks hunting, and by the improvement of structure, satisfies the excavator fuel tank detection demand of leaking hunting, and fuel tank acts freely and improves monitoring efficient.
To achieve the above object of the invention, the technical solution adopted in the utility model is: a kind of excavator fuel tank pick-up unit that leaks hunting, comprise tank, compressed air piping and source of the gas, also be provided with the weightening finish device, described weightening finish device comprises permanent magnet, balancing weight, described permanent magnet is provided with one and has externally threaded connecting link, and described balancing weight is provided with the through hole that cooperates with described connecting link, and described connecting link passes the through hole of described balancing weight, the outer end makes balancing weight fixedly connected with permanent magnet by nut lock.
Carry out the excavator fuel tank and leak hunting when detecting, at first select suitable balancing weight, it is assembled on the permanent magnet according to the specification of detected fuel tank; The permanent magnet that will have balancing weight then is adsorbed onto on the fuel tank box side; The fuel tank that will be adsorbed with permanent magnet and balancing weight at last hangs in the tank, and fuel tank is suspended under the surface level, and the sealing that then just can carry out each weld seam of fuel tank has freely detected.
Further technical scheme, described connecting link is welded in the side of described permanent magnet away from fuel tank.
In the technique scheme, the weight of described balancing weight is submerge weight poor of suffered buoyancy and fuel tank and permanent magnet of fuel tank and weightening finish device.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
1. the utility model is cancelled the thrust feedway of the tank upside that leaks hunting, and makes tank upside space clear, is convenient to putting into and taking out of fuel tank.
2. after the utility model makes fuel tank immerse in the water, can be in water flexible overturning, realize that each weld seam of arbitrary face is observed flexibly, improve detection efficiency.
3. thrust feedway---the cylinder of the utility model cancellation tank top reduces compressed-air actuated consumption.

Embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment one: referring to shown in Figure 2, a kind of excavator fuel tank pick-up unit that leaks hunting, comprise tank 2, compressed air piping 1, source of the gas and weightening finish device, described weightening finish device comprises permanent magnet 4 as shown in Figure 3, balancing weight 5, described permanent magnet 4 connects one away from a face down bonding of fuel tank 3 and has externally threaded connecting link 6, and described balancing weight 5 is provided with the through hole that cooperates with described connecting link 6, and described balancing weight 5 utilizes described through hole to hang on the connecting link 6 and by nut 7 to fixedly connected with described permanent magnet 4.
As shown in Figure 2, the permanent magnet that has balancing weight is adsorbed on the fuel tank, because the weight of balancing weight increases the overall weight of fuel tank, when fuel tank is placed in the water, effect low suspension at gravity also can overturn under surface level flexibly, and the sealing of conveniently carrying out each weld seam of fuel tank detects.
Balancing weight can be made the standard iron block that varies in weight within the specific limits, leaks hunting and can select for use at different fuel tanks when detecting carrying out fuel tank.
For fuel tank is suspended under the surface level, the suffered gravity of balancing weight is submerge weight poor of suffered buoyancy and fuel tank and permanent magnet of fuel tank and weightening finish device.Fuel tank shows slightly come-up trend when leaking hunting for assurance simultaneously, and the weight of balancing weight need be slightly less than the difference of two power.By the weight of two power difference standard configuration balancing weights, carry out the making of balancing weight then according to the standard configuration result, and carry out mark for selecting for use.Concrete computing formula is as follows:
Suffered buoyancy: F=F
