Abstract
The utility model relates to an apparatus for testing hydraulic pressure of steel cylinders, comprising a machine frame, a roll over stand, a compression head apparatus, various pressure pumps, and corresponding valves and pipes. The utility model adopts a structure that the roll over stand is hinged with the machine frame. The roll over stand is driven to rotate with 180 DEG by a power turnover mechanism. Besides, a compressed air pump is used for assisting a steal cylinder to drain water. Therefore, one apparatus can complete watering, testing and water discharging for a steel cylinder one time, and water is discharged quickly and completely. The utility model reduces labor strength and improves testing efficiency for steel cylinders.
Description
The utility model relates to the technical field of steel cylinder resistance test, lab-size equipment.
At present, in the steel cylinder production process, steel cylinder need be done the hydrostatic test one by one, and general way is to pour water in bottle with low pressure pump earlier, is forced into test pressure after filling and detects, and sheds pressure then, the water in the emptying bottle.But because that the bottle of steel cylinder is chewed is little, the water difficulty in the emptying bottle, traditional method is to allow water flow out naturally by manually bottle being reversed, and perhaps draws water with pump.Manually the labor intensity with the steel cylinder reversing is very big, and water discharge time is also long, and its inefficiency is unfavorable for that the mass production of steel cylinder detects; Be difficult to fully the water in the steel cylinder be pumped and draw water with pump.For this reason, be necessary to propose a kind of suitable mass production, steel cylinder water test unit efficiently.
The purpose of this utility model is for overcoming the deficiencies in the prior art part, provide a kind of can be with the hydrostatic testing machine for steel bottles of steel cylinder upset and Pressure water discharging, examination is surveyed, draining is once finished, draining is fast and clean, high working efficiency.
The purpose of this utility model is achieved by the following technical solution: hydrostatic testing machine for steel bottles comprises frame, lay the turning rack of steel cylinder, be arranged at the turning rack top in order to the indenter device that compresses the sealing steel cylinder and chew, steel cylinder is carried out low pressure pump that voltage-withstand test uses, hydraulic test pump and each valve and pipeline etc. accordingly, specialization is that two ends, the turning rack left and right sides are fixed with spindle nose, spindle nose and frame are hinged, and the output of the spindle nose of at least one end and power switching mechanism is in transmission connection.Further, the power switching mechanism is made of hydraulic transmission oil cylinder, tooth bar, gear, and tooth bar is fixed on the power end of hydraulic transmission oil cylinder, and with the gear engagement that is fixed on the spindle nose.In addition, also be provided with compressed air pump and valve, air can inject tested steel cylinder by the pipeline and the indenter device of hydraulic test pump.
Such structure, steel cylinder after voltage-withstand test is finished can be thrown on the turning rack, under the driving of power switching mechanism around spindle nose articulating point Rotate 180 °, bottle is chewed downwards, water in the order bottle flows out naturally, add that compressed air pump injects air by pipeline in bottle, make water in the bottle fast and pure land is discharged.
Below in conjunction with drawings and Examples structure of the present utility model and advantage are further elaborated.
Fig. 1 is a plan structure schematic representation of the present utility model.
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the part sectioned view of Fig. 2;
Fig. 4 is pump of the present utility model, pipeline connecting figure.
Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the hydrostatic testing machine for steel bottles of present embodiment is arranged at the side of steel cylinder conveyor line 18, the turning rack 3 that can place ten steel cylinders 1 is by frame 2 supportings, and turning rack 3 is hinged by the spindle nose and the frame 2 at two ends, the left and right sides, and turning rack 3 can be rotated around the spindle nose hinge.The forward and backward both sides of turning rack 3 are equipped with steel cylinder pushing in device 4 and steel cylinder ejecting device 6 respectively, steel cylinder pushing in device 4 by hydraulic jack 12, centering location push away frame 13, guide rail 14 constitutes; Steel cylinder ejecting device 6 also by hydraulic jack 15, centering location push away frame 16, guide rail 17 constitutes (as shown in Figure 1).One end spindle nose 11 of present embodiment turning rack 3 is in transmission connection with the power switching mechanism 7 that drives turning rack 3 upsets, power switching mechanism 7 is arranged at the right side of turning rack 3, constitute by hydraulic transmission oil cylinder 8, tooth bar 9, gear 10, tooth bar 9 is fixed on the power end of hydraulic transmission oil cylinder 8,10 of gears are fixed on the spindle nose 11, gear 10 and tooth bar 9 engagements (as Fig. 2, shown in Figure 3), when 10 rotations of tooth bar 9 driven gears, drivable shaft head 11 is together with turning rack 3 rotations.
Working procedure is such: steel cylinder 1 is delivered to the side of turning rack 3 by conveyor line 18, the hydraulic jack 12 of steel cylinder pushing in device 4 starts, promote the centering location and push away frame 13 along guide rail 14 feedings, thereby push ten steel cylinders 1 on the conveyor line 18 in the turning rack 3 and the automatic centering location, after steel cylinder pushing in device 4 resetted, the indenter device 5 that is arranged at turning rack 3 tops was promoted to descend by hydraulic transmission, and the bottle that is pressed in each steel cylinder 1 is chewed, implement fixing and sealing, referring to Fig. 4, this moment valve T
1Open low pressure pump P
1In bottle, pour water by indenter device 5 by pipeline, fill back low pressure pump P
1Stop valve T
1Close.Hydraulic test pump P thereupon
2Start, and, test the voltage endurance capability of each steel cylinder by pipeline and 1 pressurization of 5 pairs of each steel cylinders of indenter device, after check finishes, valve T
3Open off-load, the steel cylinder off-load is to normal pressure, and the hydraulic transmission oil cylinder 8 of power switching mechanism 7 starts, and promotes tooth bar 9 and moves upward, and makes gear 10 rotate, thereby drives turning rack 3 around spindle nose 11 rotations, until 180 ° of upsets.Like this, the steel cylinder 1 in the turning rack 3 all bottle is chewed downwards, at this moment valve T
2Open.Water in the bottle flows out naturally, meanwhile, and with compressed air pump P
3The valve T that links to each other
4Also open, the injecting compressed air in each steel cylinder by pipeline and indenter device 5, thereby the speed of quickening draining, after the water emptying in the bottle, valve T
4Close, the hydraulic transmission oil cylinder 8 of power switching mechanism 7 oppositely starts, and tooth bar 9 is walked backhaul, drives turning racks 3 Rotate 180s ° by gear 10, each steel cylinder 1 reversion previous condition, and indenter device 5 unclamps rising, removes the location to steel cylinder 1.The hydraulic jack 15 of steel cylinder ejecting device 6 starts thereupon, promotes the centering location and pushes away frame 16 along guide rail 17 feedings, and ten steel cylinders 1 on the turning rack 3 are shifted onto on the conveyor line 18 again, finishes resistance test one time.
Such design, realize many steel cylinders from pour water, pressure testing, upset, draining etc. are once finished by an equipment, draining is fast and fully, and is faster more than three times than traditional draining, both improved manufacturing efficiency widely, reduced labor intensity again.As seen, the utility model is the steel cylinder hydraulic pressure detection facility of a kind of novelty, practicality, rich intention.
