Abstract
The utility model provides a pressure test device of a jack, relating to a device for carrying out a test after the jack is overhauled. The pressure test device of the jack is characterized by structurally comprising a device rack, adjusting plate supporting steel pillars and a moving supporting frame. The rack comprises a horizontal test platform, a steel column which is vertically fixed on the horizontal test platform and a top steel horizontal beam fixedly connected to the upper end of the steel column. The adjusting plate supporting steel pillars are two vertical steel pillars which are located in the device rack and abut against the side portion. The moving supporting frame is a horizontal carrying plate. Through holes are formed in the two ends of the horizontal carrying plate and can slide up and down along the adjusting plate supporting steel pillars. According to the pressure test device of the jack, in the time of a test, the jack is placed on the horizontal test platform on the device rack, a force is exerted on a piston of the jack through a piston of a hydraulic cylinder, a pump-mounted pressure gauge is used for reading numbers, and the jack is tested. Detection and pressure testing are carried out on the maintained jack and stability of the working process of the jack is detected.
Description
Technical field
Lifting jack pressure testing device, relates to the device that carries out test experience after lifting jack maintenance.
Background technology
Lifting jack is that in upkeep operation, one of indispensable equipment ， manufacturing enterprise can have a considerable number of various lifting capacities, the lifting jack of all kinds of models conventionally, in various kinds of equipment service work, plays an important role.But the singularity while using because of lifting jack, while requiring to use, must guarantee being perfectly safe of it, and the maintenance, repair of lifting jack self are being related to whether it can use safely, particularly overhaul later test experience and be the key link in it self maintenance process.
At present, at lifting jack, after maintenance, repair, carry out no-load test, be directly used in working-yard after qualified.Due to useless, carry out rated pressure test, often occur at the construction field (site) lifting jack automatic fall-back, do not reach the phenomenons such as regulation lifting capacity.These phenomenons not only affect operating efficiency, increase construction cost, and particularly, when utilizing lifting jack combination process, the safety of construction in serious threat.
Summary of the invention
The purpose of this utility model is exactly the deficiency existing for above-mentioned prior art, provides a kind of and can detect pressure testing to the later lifting jack of maintenance, repair, detects the lifting jack pressure testing device of its course of work stability.
The purpose of this utility model is achieved through the following technical solutions.
Lifting jack pressure testing device, is characterized in that its structure comprises:
Device frame, this frame comprises: a horizontal bed, is vertically fixed on steel column and the top steel horizontal gird that is fixed in steel column upper end on horizontal bed;
Adjustable plate brace steel post; This steel column be two be positioned at device frame, the vertical steel column of the portion of keeping to the side;
Movable support frame; This support is a horizontal supporting plate, the through hole that this two ends of bearing plate has can be on adjustable plate brace steel post, slide up and down.
Lifting jack pressure testing device of the present utility model, during test, lifting jack is put on the horizontal bed in device frame, the piston of logical hydraulic cylinder is to the jack piston application of force, lifting jack is tested, the detection pressure testing of realization to the later lifting jack of maintenance, repair, detects its course of work stability.
Accompanying drawing explanation
Fig. 1 is structure pictorial diagram of the present utility model.
Embodiment
Lifting jack pressure testing device, its structure comprises:
Device frame, this frame comprises: a horizontal bed 1, is vertically fixed on steel column 2 and the top steel horizontal gird 3 that is fixed in steel column upper end on horizontal bed;
Adjustable plate brace steel post 4; This steel column be two be positioned at device frame, the vertical steel column of the portion of keeping to the side;
Concrete operation step is as follows:
Pressure testing lifting jack is positioned over to pressure testing device platform, and lifting jack raises and withstands the horizontal supporting plate of movable support frame, executes heavily on horizontal supporting plate, after lifting jack carrying, opens counterclockwise surplus valve, has fluid to overflow in time closing outflow valve clockwise.Adjusting surplus valve makes tensimeter indicated value increase to gradually required pressure.
Pressure testing lifting jack be placed in horizontal supporting face on, plunger is at maximum lifting height, top central vertical acts on the rated load of surface level, start supercharging, reach after lifting jack rated pressure value scope, stop supercharging, check that each parts of lifting jack must not have plastic yield or other abnormal occurrencies.
After the supercharging of pressure testing lifting jack, do not reach rated pressure value or the dwell time does not reach requirement, when plastic yield and other abnormal occurrencies appear in each parts, this lifting jack is defective.Otherwise be qualified, can continue to use.
