Description

The guide tracked lifting platform device of chimney

Technical field

The utility model belongs to the architectural furniture technical field, relates to a kind of chimney lifting platform device that is used for chimney structure concrete casting construction.

Background technology

At present, hydraulic sliding mould construction technology and device in the building operations of reinforced concrete chimney, have been adopted more at large.Though this technology and device have characteristics such as construction period weak point, but exist some insoluble problems also, it mainly shows: owing to adopt hydraulic jack to come supporting template to rise in the construction, and the lifting of template often is to carry out under less than the situation of 1MPa at the last pouring sections of chimney wall concrete strength, so not only to expend steel in a large number, it is coarse also to be prone to concrete surface, chimney wall is easily by the drift of drawing crack and working platform generation center or phenomenon such as reverse, thereby causes being difficult to guarantee such as construction quality, construction safety lacks the generation of problems such as guarantee and execution control complexity.

The utility model content

The purpose of this utility model is the problem that prior art exists is solved, so provide a kind of simple in structure, save steel, the guide tracked lifting platform device of construction period chimney short, easy to operate, that can guarantee chimney construction quality and working security.

The technical solution that adopts is so for achieving the above object: the guide tracked lifting platform device of the chimney that is provided is by forming with a peaceful derrick and a cover guide rail hoisting mechanism.Be erected at guide rail hoisting mechanism top with peaceful derrick, being fitted with on it shakes the head hang material gin pole, radiation beam, central dram circle, in hang platform and Lifting basket etc.On the concrete tube wall of guide rail hoisting mechanism attached to chimney, it is formed by load track plate and by handling frame and hoisting frame that power set (hydraulic means or electronic deceleration device) drive, wherein load track plate is made of channel-section steel, it is installed on the barrel by two secondary split bolts, hoisting frame is set in the handling frame, the both sides of handling frame are provided with the channel-section steel guide rail, the roller that can roll and climb in the channel-section steel guide rail is being housed on the two side of hoisting frame, on handling frame and hoisting frame, also is being respectively equipped with a plurality of being used for and fixing handling frame hook and the hoisting frame roller pin that connects dress of load track plate.In the work, power set are located on the hoisting frame, and handling frame is being born the load with peaceful derrick.

The process that this device is committed to chimney construction is such: get load track plate it is adhered on the installation steel concrete barrel under construction by the mode of being arranged above and below successively by split bolt spare separately, hydraulic pressure or electric type power device are installed on the hoisting frame of guide rail hoisting mechanism, and hoisting frame is fixed on down in the pin-and-hole default on the load track plate by the hoisting frame roller pin; The forward device that turns on the power makes the power set that are fixed on the hoisting frame drive handling frame and rises along the hoisting frame roller, reach predetermined altitude after, in load track plate preformed hole, insert force-bearing pin, and make the hook of handling frame both sides hang the jail on force-bearing pin; Afterwards the fixed solution between hoisting frame and load track plate is removed, the device that oppositely turns on the power makes hoisting frame two side wheels up along handling frame channel-section steel guide rail, and then hoisting frame is that fulcrum rises along the load track with the handling frame; After putting in place, still fixed hoisting frame by the mode that the hoisting frame roller pin is fixed in the track plate pin-and-hole; On handling frame that has promoted and suspension bracket, install then, adjust, fixing inner and outer template, to radius, placing of concrete is laid bricks; Again from the disengaging of having constructed the concrete tube wall of handling frame bottom remove a joint load track plate, connect on original load-carrying member plate above, use after the leveling drawing female screw bolt to be fixed on the concrete tube wall; Hook on the unclamp operation frame, the forward device that turns on the power rises handling frame, and the handling frame fixing back in place and then the device that oppositely turns on the power again rise hoisting frame; Cycling is so again and again alternately risen load track plate, handling frame and hoisting frame, finally finishes the work progress of whole chimney structure.

The utility model is when being used for the construction of chimney structure; whole device is all attached on the steel concrete barrel; handling frame and hoisting frame promote mutually by the rotating of power; itself also rises device along with the rising of structure, can realize the synchronous construction of steel concrete barrel (urceolus), haydite concrete barrel (inner core), liner, cat ladder, signal platform etc. thus.The connection up and down of load track plate is simple and reliable in the guide rail hoisting mechanism, they both can be as the part of template in work progress, be again the hard point of all objects such as derrick, platform, hanging basket, controlled the radius of load track plate on barrel, also just controlled the radius of chimney.In addition, owing to adopted the multi pack mode that guarantees safety work, the guide rail hoisting mechanism is that the strong point promotes with load track plate, and all the load of construction equipment self is born by the barrel concrete structure that has certain intensity, steel had so both been saved, shortened the construction period, overcome again in the hydraulic slip-form technology that the concrete surface that occurs easily is coarse, chimney wall is easily by drawing crack and the drift of working platform generation center or phenomenon such as reverse, make quality of concrete that technologic assurance arranged, the physical dimension that chimney is constructed also is easy to control.Simple and reasonable, convenient and reliable operation of the present utility model, applied range and compliance are strong, and is all applicable to large-scale and small-sized chimney structure constructions such as monotubulars, sleeve, many.With regard to sliding form apparatus, can not construct winter, and device described in the utility model can be constructed in whole winter.
