6results about How to "Fast pouring" patented technology

The utility model discloses a kind of rapid pouring mould of assembly integral type two-way dense rib composite floor slab prefabricated concrete bottom plate, including bottom plate, first intermediate plate, second intermediate plate, first side edge plate, second side edge plate and third side edge plate.The pouring mould in the utility model has fast pouring speed, is easy to vibrate, easy to demould, can greatly reduce construction error and construction difficulty, while improving pouring efficiency, realize the promotion of assembly building efficiency.

A motorcycle main pump blank pouring mold, including lower mould (1), upper mould (2) and core-pulling block (3), lower mould (1) top is opened with profiled lower groove (4), one end of profiled lower groove (4) is pouring opening, the other end of profiled lower groove (4) is opened with core-pulling lower groove (5), upper mould (2) bottom is opened with profiled upper groove (6), one end of profiled upper groove (6) is pouring opening, the other end of profiled upper groove (6) is opened with core-pulling upper groove (7); The advantages are: fast pouring speed, after pouring is finished, the core-pulling block is directly pulled out after mold opening, and the casting can be taken out, and the production efficiency is high.

The invention relates to the technical field of unloading and conveying devices, in particular to an automatic alumina powder unloading and conveying device which comprises a box body and a bottom plate which are rotationally connected, a partition plate is fixed to the inner side of the box body, the partition plate divides the box body into a warehouse and an equipment warehouse in the vertical direction, and a cylindrical cavity is formed in one end of the equipment warehouse; a discharging mechanism is arranged on the inner side of the cylindrical cavity, and a communicating opening and a discharging opening which communicate with the warehouse and the outside correspondingly are formed in one side of the cylindrical cavity. And a discharging extending mechanism is arranged at one end of the discharging opening. The box body is turned over through the two lifting oil cylinders, meanwhile, an alumina powder material in the box body is poured outwards at a constant speed through the discharging mechanism, the situation that the pouring speed is too high due to the fact that the material located at an outlet of the box body is extruded by the material in the box body can be prevented, and therefore the alumina powder can be well prevented from drifting away into the air; therefore, the pollution to the atmosphere is reduced, and the waste of materials is reduced.

The utility model relates to expansion joint glue injection device technical field, concretely is a kind of high-pressure glue injection device for elastomer expansion joint material.The device includes base, high-pressure injection cylinder being set on base, filling mechanism for conveying glue to high-pressure injection cylinder, piston is slidably arranged on the inner side wall of high-pressure injection cylinder, driving mechanism for driving the linear sliding of high-pressure injection cylinder is set on the base;High-pressure injection cylinder is connected with the tail end of conveying long tube, and the first valve is set in the head end of conveying long tube.The characteristics of the device are that by pushing piston, great pressure is applied to the glue in high-pressure injection cylinder, so that the glue overcomes its own gravity and viscosity, and is injected into the use position after climbing a large difference.The device has simple structure, can quickly realize the purpose of pouring elastomer material directly from under bridge to bridge joint, and meets construction demand.

The utility model relates to the technical field of tunnel construction, in particular to a tunnel groove formwork trolley which comprises a trolley body capable of moving in a tunnel, the two sides of the trolley body are each provided with a walking mechanism, a positioning mechanism, a formwork supporting mechanism, a concrete pouring chute mechanism and a demolding mechanism, the structure is reliable, operation is convenient, the pouring speed is high, and the working efficiency is high. The whole construction cost is low, the functions of automatic walking, automatic formwork erecting, automatic demolding and the like are achieved, the labor intensity is greatly reduced, the requirement for constructors is reduced, in addition, the trolley is provided with the walking mechanism, a formwork can be easily moved to the next pouring section through the walking system after demolding, and operation is extremely convenient and fast. Compared with a traditional split mounting type formwork, the ditch cable trough trolley can achieve double-side synchronous construction, and three sections of formworks are alternately used. And the construction efficiency is obviously improved. And the hydraulic system controls the lifting and transverse movement of the template, so that the positioning is simple and accurate.

The invention discloses a method for sealing the bottom of concrete under direct injection water. The method comprises the following steps that construction is prepared; first seal condition acceptance; pouring construction is conducted through the first row of main guide pipes according to the prepared positions of the first row of main guide pipes to the last row of main guide pipes which are sequentially arranged in the cofferdam from upstream to downstream in advance; pouring construction is conducted through the second row of main guide pipes; pouring construction is conducted through the next row of main guide pipes till the last two rows of main guide pipes; pouring construction is conducted through the last row of main guide pipes; pouring construction is conducted through the last but one row of main guide pipes; and ending construction. The method has the beneficial effects that a novel method, namely a direct filling bottom sealing method, is adopted, and the defects that a traditional central concentrated feeding pouring period is long, procedures are complex, cross construction is more, and the concrete retarding requirement is high are overcome. By means of the method, the pouring speed is high, the pouring quality is high, equipment investment is small, functional areas are clear, cross-free construction is achieved, the single-time pouring amount is large, and the construction period is short.
