Abstract
Disclosed is a jack for mechanics experiments. The interval of anchor ring holes of an optimized existing anchorage device is too small, and the physical dimension of supporting legs of a jack of 27 tons is too larger, so that difficulties are brought to the pretension; and the self-weight of the jack of 27 tons is over 20kg, so that the labor intensity of experimenters is high. The jack for the mechanics experiments comprises a center penetrating sleeve (10), both ends of the center penetrating sleeve are connected with a tool clip lever (6) and a rear pressing cover (11) respectively, the tool clip lever is connected with a tool clip (4) and a pressing spring (7) respectively, the tool clip is connected with an anchor removing sleeve (2), the tool clip and the anchor removing sleeve are mounted on a tool anchor ring (3), supporting legs are sleeved outside the anchor removing sleeve and the tool anchor ring, a piston (9) is mounted between the center penetrating sleeve and an outer cylinder (8), and an oil nozzle joint (5) is mounted on the outer cylinder.
Description
Technical field:
The utility model relates to a kind of Experiments of Machanics jack.
Background technology:
At present domestic when doing the ground tackle static test, generally all adopt 27 tons of jacks during the pretension steel strand, and predetermincd tension generally only is 1 ton~2 tons, error is bigger, and the win or lose of ground tackle static test has much relations to every steel strand predetermincd tension is whether consistent.Cause the ground tackle disqualified upon inspection than mistake during with 27 tons of jack pair steel strand pretensions.
At present ground tackle is less than normal through optimal design anchor ring pitch of holes, and the spike physical dimension of 27 tons of jacks is bigger, and for pretension brings certain difficulty, and 27 tons of jacks deadweights have more than 20 kilogram, and experimenter's labour intensity is big.
Summary of the invention:
The purpose of this utility model provides a kind of Experiments of Machanics jack.
Above-mentioned purpose realizes by following technical scheme:
A kind of Experiments of Machanics jack, its composition comprises: the punching cover, the two ends of described punching cover are connected with instrument intermediate plate depression bar, rear pressing cover respectively, described instrument intermediate plate depression bar is connected with instrument intermediate plate, stage clip respectively, described instrument intermediate plate with unload anchor cover and be connected, described instrument intermediate plate, the described anchor cover that unloads are installed in the instrument anchor ring, described unloading on anchor cover, the described instrument anchor ring is with spike, between described punching cover and the outer shell piston is installed, the oil nozzle joint is installed on the described outer shell.
Described Experiments of Machanics jack, described stage clip is installed on the interior axle of described punching cover, described piston is connected with described instrument anchor ring, described spike respectively, described instrument anchor ring respectively with describedly unload the anchor cover, described instrument intermediate plate is connected.
Beneficial effect:
Free state of the present utility model is jack piston when getting back to the end, unloads anchor and is enclosed within the effect of piston, backs down the instrument intermediate plate, and at this moment prestress wire can freely be come in and gone out in the jack; When being in tensile state, jack tension oil nozzle fuel feeding, piston are to left movement, and the instrument intermediate plate clamps prestress wire under the effect of instrument intermediate plate depression bar and instrument intermediate plate stage clip, and the jack tension oil nozzle continues fuel feeding until finishing the stretch-draw action; When being in the backhaul state, the off-load of stretch-draw oil nozzle, backhaul oil nozzle fuel feeding, piston moves right, and when piston was got back to the end, drive was unloaded the anchor cover and backed down the instrument intermediate plate, finished the backhaul action, and is easy and simple to handle, high efficiency.
Description of drawings:
Accompanying drawing 1 is structural representation of the present utility model.
The specific embodiment:
