The jacking system that a kind of drilling platform is used is to torsional test machine
Technical field
The utility model relates to the jacking system technical field of measurement and test that drilling platform is used, and refers in particular to jacking system that a kind of drilling platform uses to torsional test machine.
Background technology
Known in the industry, lifting system of self-lifting well drilling platform comprises machinery and electric two parts, mechanical part is lifting unit, this part needs to carry out the stand under load checking under each operating mode after assembling completes, to guarantee the stability of product, in addition, also need to simulate the various states of electric part in actual motion, yet, also do not have now one conveniently equipment can complete this task.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides jacking system that a kind of drilling platform reliable, simple to operate reasonable in design uses to torsional test machine.
For achieving the above object, technical scheme provided by the utility model is: the jacking system that a kind of drilling platform is used is to torsional test machine, it comprises the first lifting unit with electro-motor, the second lifting unit with magnetic powder brake, horizontally disposed to torsional test frame and load bearing roller chain, wherein, level is arranged on the first lifting unit in torsional test frame and the second lifting unit is connected to this to torsional test frame by transmission shaft respectively, article two, the other end that transmission shaft connects is respectively equipped with the first climbing gear and the second climbing gear, and load bearing roller chain is located at the first climbing gear and the second climbing gear below, load bearing roller chain respectively and between the first climbing gear and the second climbing gear, be provided with the close-fitting horizontally disposed main tooth bar with three.
Described is provided with electric-control system to torsional test frame one side, and this electric-control system is electrically connected to electro-motor and magnetic powder brake respectively.
The utility model is after having adopted such scheme, by regulating the current value of magnetic powder brake, make detent produce the torque needing, system is had and load identical under each operating mode, thereby the stability of check product, and electric part is by the state of the open and close Simulations self-elevating drilling platform operation of each pilot lamp in electric-control system, reach the object of experiment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail.
Shown in accompanying drawing 1, the jacking system that drilling platform described in the present embodiment is used is to torsional test machine, it comprises the first lifting unit 4 with electro-motor 6, the second lifting unit 8 with magnetic powder brake 5, horizontally disposed to torsional test frame 1 and load bearing roller chain 3, wherein, level is arranged on the first lifting unit 4 in torsional test frame 1 and the second lifting unit 8 is connected to this to torsional test frame 1 by transmission shaft respectively, article two, the other end that transmission shaft connects is respectively equipped with the first climbing gear 9 and the second climbing gear 10, and load bearing roller chain 3 is located at the first climbing gear 9 and the second climbing gear 10 belows, this load bearing roller chain 3 respectively and between the first climbing gear 9 and the second climbing gear 10, be provided with the close-fitting horizontally disposed main tooth bar 2 with three.After experiment starts, starting electro-motor 6 drives the first climbing gear 9 to rotate, make the back and forth tangential movement in the horizontal direction of main tooth bar 2, and drive the second climbing gear 10 to rotate, effect due to load bearing roller chain 3, guaranteed that motion is for rolling friction, reduced the frictional resistance producing under sliding friction, it is more accurate that load is demarcated, now, by regulating the current value of magnetic powder brake 5, make detent produce the torque needing, hinder the second climbing gear 10 to rotate, thereby jacking system is had and load identical under each operating mode, stability under each operating mode of verification system, in addition, described is provided with electric-control system 7 to torsional test frame 1 one sides, this electric-control system 7 is electrically connected to electro-motor 6 and magnetic powder brake 1 respectively, the state of the open and close Simulations self-elevating drilling platform operation by each pilot lamp in electric-control system 7, as normal, rise ship operation, ship operation is fallen, pile pulling operation, piling operation, and the action such as stopping in emergency under special circumstances, thereby reach the object of checking electric part.
The examples of implementation of the above are only the preferred embodiment of the utility model, not with this, limit practical range of the present utility model, therefore the variation that all shapes according to the utility model, principle are done all should be encompassed in protection domain of the present utility model.
