Abstract
The utility model relates to a plugging device for a blow-off mechanism of a concrete pump tank, which provides a plugging device with simple structure and convenient operation. The utility model has the technical scheme that the plugging device comprises an end plug and a blow-off mouth, wherein a longitudinal through hole is arranged in the end plug, the outer circumference is a conical surface whose upper end is big and the lower end is small, a screw rod is arranged in the through hole, and the end plug is fixed to the lower end of the screw rod. The screw rod above the end plug is connected with a fixed plate whose upper end is provided with a pressing nut. A taper hole whose upper end is big and the lower end is small is arranged in the blow-off mouth, the end plug is inserted into the taper hole and is matched and sealed with the blow-off mouth. The practical use shows that the plugging device has the advantages of simple structure, low cost, convenient operation and strong practicality.
Description
Technical field
The utility model relates to a kind of water-drainage mechanism, particularly relates to the blocking device of concrete pump tank water-drainage mechanism.
Background technique
Between the concrete cylinder and master cylinder of towed concrete pump, generally connect by tank.When actual pump concrete, topped up with water in the tank plays cooling, lubrication to concrete piston, also can whether judge the wearing for piston situation by the muddiness of water.And the tank blocking device of concrete pump generally is screw thread water nozzle of weldering on the tank base plate, refills a ball valve, when needing the water in the tank bled off, directly hand is reached and opens ball valve below the tank and get final product.There is following defective in this blocking device, when being arranged below the tank very, big operating space can operate easily, and do not limit the randomness of draining, but when the bottom of gullet space very hour, staff can't be stretched down operation at all, and arbitrarily draining again, in this case, existing water seal block apparatus just can not be realized the purpose that discharges water.
Summary of the invention
The utility model is exactly in order to overcome the deficiency of above-mentioned existing jettison gear, to provide a kind of simple in structure, blocking device that can easy-to-operat in any operating space.
The technical solution of the utility model is: a kind of blocking device, comprise plug, faucet, and band longitudinal hole in the plug, excircle is the up big and down small conical surface, is provided with a screw rod in the through hole, plug is fixed on the lower end of screw rod; Connect a fixed plate on the screw rod above the plug, the fixed plate upper end is provided with gland nut; The up-small and down-big taper hole of band in the described faucet, plug inserts in the taper hole, with the faucet fitted seal.
Above-mentioned can making with metal or plastics, better with the plug using effect that high strength, elastomeric polyurethane material are made.During use, jettison gear is fixed on the tank side panel with fixed plate.During sealing, screw rod is rotated down plug jam-pack faucet; When discharging water, rotate up screw rod and on carry, move on the plug, water just can flow out from faucet.
The utility model structure is very simple, and cost is extremely cheap again, operates easily, and practicability is very strong.
As further improvement of the utility model, connect a perpendicular hand lever in screw tip, rotary screw is more convenient to operate.
At the plug two ends primary nut is set, plug can be fixed on the faucet position better, can slippage.

Embodiment
Embodiment 1
As shown in Figure 1, a kind of blocking device is made up of hand lever 1, gland nut 2, fixed plate 3, screw rod 4, primary nut 5, packing ring 6, plug 7.Plug 7 is to make with high strength, elastomeric polyurethane material, and interior band longitudinal hole, excircle are the up big and down small conical surfaces, and plug 7 two ends are fixed by primary nut 5 and are pressed on the lower end of screw rod 4; Hand lever 1 is welded into-body with screw rod 4; Fixed plate 3 is connected on the screw rod 4 by screw, by bolt with whole stifled being fixed on the tank side panel that discharge water.
Specify below and how to realize: as shown in Figure 1, after the stifled screw rod 4 that will discharge water earlier directly passes from fixed plate 3, lower end primary nut 5, packing ring 6, plug 7 are installed, again fixed plate 3 is fixed by bolts on the tank side panel; The stifled plug that will discharge water is then compressed into the faucet below the tank base plate, this faucet be in up-small and down-big taper hole, taper hole upper end and the plug fitted seal that discharges water stifled, by fixed plate 3, big nut 2 that it is closed and locked at last.When needs discharge water, directly rotate hand lever 1 unscrew screw rod and on carry and getting final product.In addition, the faucet periphery is made the well-thought-out plan joint, can directly put a flexible pipe and guide to the ground that can discharge, and the sewage of draining just can arbitrarily not trickle.Show that through use this water-drainage mechanism structure is very simple, cost is extremely cheap again, operates easily, and practicability is very strong.
