Description
Technical field
The present invention relates to the big particle diameter aggregate of a kind of later-model cement concrete windrow device, in the use of concrete gravel system of processing, can prevent effectively that aggregate from producing second-time breakage and separating with grating in the process of storing up.Especially be applicable to that aggregate Da Shi (40-80mm) stores up work with the conveying of especially big stone (80-150mm) in the waterwork industry concrete gravel aggregate system of processing.
Background technology
Da Shi (40-80mm) that existing concrete for hydraulic structure building engineering is required and especially big stone (80-150mm) aggregate all are to store up through the mode of sealing-tape machine fixed point blanking after screening building discharging usually.In the process of storing up, tend to make aggregate to produce broken and segregation in various degree.Behind aggregate fragmentation and the segregation, just destroyed the original grating of cement concrete, and because broken and all non-definite value of isolation rate cause batching plant to mix very difficult adjustment proportioning grating when making cement concrete.In addition, owing to increased face area after the aggregate fragmentation, have only the cement consumption of increasing to guarantee concrete quality.So not only increase cost, and increased the difficulty in the aggregate cooling, be unfavorable for the control of concrete construction quality.
" concrete construction standard " DLT5144-2001 according to country's promulgation stipulates that the inferior footpath of aggregates at different levels should not surpass the technical requirements that the minimum blanking height of the above big particle diameter aggregate of 40mm is not more than 3m greater than 10%.Generally speaking, aggregate is during from screening building discharging, and grating is more continuous, and code requirement generally can both be satisfied in inferior footpath.Owing to adopt the mode of the storing up windrow of sealing-tape machine fixed point blanking; Cause the second-time breakage and the segregation of aggregate easily; The inferior footpath of the aggregate of storing up index generally between 10%～20%, causes the aggregate Da Shi (40-80mm) and the aggregate quality of especially big stone (80-150mm) specification can not satisfy the requirement of national regulation rule.Thereby taking conventional technology remedial measures is before the batching plant feed system of mixing, need carry out regrading to handle.
Summary of the invention
The technical matters that the present invention will solve provides the windrow device of the big particle diameter aggregate of a kind of cement concrete; This device is when carrying big particle diameter finished aggregate; Sealing-tape machine can be controlled the feed height windrow material of going forward side by side effectively, prevents the second-time breakage of big particle diameter aggregate in the process of storing up, and can control inferior footpath index that the second-time breakage of big particle diameter aggregate in the process of storing up increase effectively in 2%; And keep grading of aggregates continuous; Avoid aggregate separated, solve the unreasonable concrete disintegration problem that causes of coarse aggregate size, to guarantee the requirements for quality of aggregate.
The objective of the invention is to realize like this: the windrow device of the big particle diameter aggregate of a kind of concrete; Comprise pylon, pylon is installed on the steel column, and steel column is provided with the hoist engine workbench; On the hoist engine workbench, be provided with two hinged-supports, movable outstanding back of the body girder truss is connected with hinged-support by pivot pin; Hoist engine is installed on the hoist engine workbench, and sealing-tape machine is installed on the movable outstanding back of the body girder truss, and the steel wire rope of hoist engine is connected with movable outstanding back of the body girder truss by two assembly pulleys, and drag-line one end fixes on the ground by adjusting lever, and the other end is connected with pylon.
Two hinged-supports are arranged on the winch workplatform along sealing-tape machine axis symmetry direction.
The outstanding back of the body of activity truss girder divides the head connecting section, and connecting section, afterbody connecting section are formed in the middle of the truss, and three parts connect through the mode of Bolt Connection.
Innovative point of the present invention: adopt the windrow device of the big particle diameter aggregate of cement concrete provided by the invention to adopt the scheme of stocker to compare with prior art; Saved and purchased the purchasing of stocker equipment, transported, installation and over-the-road expense, reduced construction area and civil engineering costs; Compare with the scheme that adopts sealing-tape machine fixed point blanking to store up; Avoid the second-time breakage of big particle diameter aggregate in the process of storing up in can be to greatest extent; Reduce the inferior footpath index 8%～18% of big particle diameter aggregate, it can guarantee that grading of aggregates is continuous simultaneously, avoids aggregate separated; Solve the unreasonable concrete disintegration problem that causes of coarse aggregate size, to guarantee the requirements for quality of aggregate.Use it, can save construction fund, cut down the consumption of energy; Utilize less fund in less place scope, both can increase the volume of storing up of aggregate, help the temperature control of temperature system aggregate; Can reduce construction noise again; Prevent the floating dust pollution ambient environment, reduce the workyard and take to have that cost is low, easy to use, the characteristics of energy-saving and environmental protection.
