Abstract
The utility model discloses an unloading sand box and in particular relates to an unloading casting box used for bearing heavy objects. The unloading sand box comprises an upper center for bearing loads and a sand box which is arranged below the upper center and is sheathed with the upper center, and a water-proof sealing ring is arranged at the sheathing position of the upper center and the sand box; wherein, dry standard sands or medium coarse sands are filled in the sand box, a sand outlet and a plug screw matched with the sand outlet are opened at the side surface of the lower part of the sand box. The unloading sand box has few equipment, low cost, convenient operation and stable load bearing, and is energy saving and environmental protective.
Description
(1) technical field
The utility model relates to a kind of off-load sandbox, specifically relates to a kind of off-load sandbox that put on big weight top that is used to carry.
(2) background technology
Along with Chinese economic development, highway, these bigger engineerings of railway are also more and more, and highway, the railway beam that falls adopts large-tonnage jack that it is carried usually at present, waiting construction to finish, and the jack off-load is reclaimed.But because large-tonnage jack itself is heavier, volume ratio is bigger, large-tonnage jack also will be equipped with special high-pressure oil pump, hydraulic oil pipeline and fixture thereof in addition, and its underpart also will be provided with backing plate, with the base fixed that guarantees its installation, smooth, cause that the large-tonnage jack difficulty is set in the building site is bigger; In addition, large-scale jack acquisition expenses costliness.Mainly by hydraulic lifting, its oil feed line node is many for large-tonnage jack, and leakage point is more relatively, and use jack often to need to carry weight one month or the longer time in this occasion, along with the leakage of hydraulic oil, jack pushing tow height descends to some extent, causes construction error easily.And the used hydraulic pump of this system itself needs to consume certain chemical fuel, can cause the basic demand of certain pollution and the national energy-saving and emission-reduction of being advocated at present to disagree to environment.
(3) summary of the invention
The utility model causes site requirements height, space requirement big at present use jack as the load equipment of highway, construction of railways decline beam, and cost height, the defective that maintenance cost is high, provide that a kind of device therefor is few, cost is low, be convenient to operation, to hold lotus stable, and the off-load sandbox of energy-conserving and environment-protective.
For achieving the above object, the technical solution adopted in the utility model is:
The utility model off-load sandbox, comprise the last top heart that is used for bearing load and be positioned at below it sandbox with its socket, both are provided with waterproof grommet by socket place, are filled with dry standard sand or medium coarse sand in its cheek, the plug screw that side, its underpart has sand outlet and is mated.
Above-mentioned off-load sandbox, the described upward top heart and sandbox are hollow cylinder, hold in the heart on last top and the sandbox lower end is respectively arranged with cross sectional area seat of honour tube sealing mouth and following tube sealing mouth greater than both.
Above-mentioned off-load sandbox, the described top interior portion that goes up is filled with concrete.
The utility model off-load sandbox comprises the two large divisions, be respectively the top heart and sandbox, the last top heart directly is used for load-bearing, be filled with sand in the sandbox, last top heart load passes to sandbox by sand, in case after the sand compacting, under the stable situation of load, volume can not change basically, so the utility model is very suitable for the load-bearing to longer load of time, and its stability very heavy very good more than based on hydraulic principle, and sand itself is mobile relatively poor, sealing neither can produce leakage a little, and it is very good again to hold lotus stability.And it does not need the hydraulic means that adds yet, can not produce additional leakage point, thereby when saving cost, has significantly reduced the equipment use amount, has reduced the regular maintenance expense yet.In daily use, need not safeguard that operation is simple more than hydraulic system to it.Because with respect to original hydraulic jacking device, the utility model has been saved hydraulic power system, has reduced the consumption of fossil fuel, meet the basic demand of country to energy-saving and emission-reduction.Subparticle has the characteristic of fluid, in the drain charge process, and can be as the slow leakage of fluid.But this solid particle can not be intake, and not so can lump and loses flowability, so the utility model is provided with waterproof seal ring at the last top heart and sandbox junction, has prevented that water from entering sandbox, keeps internal standard sand or medium coarse sand to be in dry state.
(4) description of drawings
Fig. 1 be the concrete real-time mode of the utility model structural representation.
Among the figure: 1, seal at the seat of honour, 2, go up the top heart, 3, concrete, 4, waterproof seal ring, 5, sand, 6, sandbox, 7, sand outlet, 8, plug screw, 9, following seal.
(5) specific embodiment
Specify structural principle of the present utility model below in conjunction with Figure of description:
With reference to explanation accompanying drawing 1, this specific embodiment off-load sandbox, comprise the last top heart 2 that is used for bearing load and be positioned at below it sandbox 6 with its socket, both socket places are provided with waterproof grommet 4, be filled with dry standard sand 5 in its cheek, side, its underpart has sand outlet 7 and is mated plug screw 8.All adopt spiral steel pipe for the sandbox and the last top heart, the intensity height, selection range is wide, is convenient to the sealing of junction.For selecting for use of standard sand, must guarantee that it is in dry state, can not have caking.In addition, if select for use the top heart and sandbox volume bigger, when highly higher, medium coarse sand can meet the demands fully, and if to go up the top heart relative with the sandbox volume less, and height is hour, just needs to have selected mobile better standard sand.
For adopting this hollow cylinder of spiral steel pipe, its upper and lower is not enough to bearing load, and hold in the heart on the top and the sandbox lower end is respectively arranged with cross sectional area seat of honour tube sealing mouth 1 and following tube sealing mouth 9 greater than both so go up.And in order to make the top heart obtain load stability and the requirement of strength of himself, its inside is filled with concrete 3.
Claims (3)
1. off-load sandbox, it is characterized in that: comprise the last top heart (2) that is used for bearing load and be positioned at below it sandbox (6) with its socket, both socket places are provided with waterproof grommet (4), be filled with dry standard sand or medium coarse sand (5) in its cheek, side, its underpart has sand outlet (7) and is mated plug screw (8).
2. off-load sandbox according to claim 1, it is characterized in that: the described upward top heart (2) and sandbox (6) are hollow cylinder, and last top is held in the heart and the sandbox lower end is respectively arranged with seat of honour tube sealing mouth (1) and following the tube sealing mouth (9) of cross sectional area greater than both.
