Description

The adjustable tubular type of building tower captain's degree adheres to bar

Technical field

The adjustable tubular type of building tower captain's degree adheres to bar, belongs to the realm of building construction tower machine attachment device.

Background technology

In the industrial civil building construction, the tower machine is indispensable heavy mechanical equipment.Tower machine type is multiple, and the bar that adheres to of tower machine is generally truss-like and circular pipe type, wherein circular pipe type to adhere to bar the most common, the quantity of such tower machine is also the hugest.The position of foundation for tower crane is subjected to foundation position, form and the size of building, multiple factor affecting such as the architectural composition of building, version and overall dimensions, its position can only be determined with on-site actual situations, the uncertainty that this has just caused the tower machine to adhere to pole length.Design and manufacturer as the tower machine, a kind of tower machine of model only provides a kind of standard to adhere to bar, this adheres to club shaft length fixes, and there only have the less leading screw of adjusting range to make this standard adhere to the length adjustment scope of bar as micro-adjusting mechanism to be less, uses limitation bigger.Adhering to when the tower machine is used in the camp site that adjustable-length that in a single day pole length exceed gauge member can only order to the manufacturer of tower machine can not the nonstandard bar that adheres to of general-duty.Above content has caused adhering to the repetition process and remould or the discarded in a large number phenomenon of material of bar.A kind of flexible bar that adheres to is also arranged by adjusting inside and outside pole length and adhering at present with bar inside and outside the lock clasp, this degree of utilization that adheres to comparatively heavy difficult transportation, material low and in case inside and outside bar deform, to be difficult to realize the relative position adjustment of inside and outside bar, thereby be difficult for promoting.

The utility model content

The technical problems to be solved in the utility model is: overcome the problem that prior art exists, design a kind of can being implemented in than adjustable in the length scope, as can the to satisfy the camp site needs adjustable tubular type of building tower captain degree and adhering to bar according to the requirement of camp site.

The technical scheme that its technical matters that solves the utility model adopts is: the adjustable tubular type of this building tower captain's degree adheres to bar, comprise the body of rod, adjust leading screw, connect conehead, the body of rod one end connects adjusts leading screw, adjust the leading screw other end and connect conehead in succession, it is characterized in that: the body of rod is multi-section combined, every section equal welded flange in body of rod two ends, the multistage body of rod is fixed as one by the high strength bolt combination by flange and the internal lining pipe that places in the flange middle part to be welded with pad, and body of rod two ends all connect conehead in succession by adjusting leading screw.

Every section body of rod is not isometric, and the shortest is to adjust the length-adjustable twice of leading screw, and all the other are for adjusting the length-adjustable two-fold integral multiple of leading screw.

The cross-sectional plane of the body of rod can be made as a kind of in circular or square or the triangle tubing, and flange can be made as a kind of in collar plate shape or square or the triangle.

For the pole length setting range is adhered in increase, adhere to former that bar is split as the multi-section compound rod that meets certain modulus and at each compound rod two ends welded flange, adopt high strength bolt to connect compound rod.

For eliminating the weak link of flange connections, add the internal lining pipe that is welded with pad at each flange connections, the internal lining pipe cross section resistance moment of choosing is not less than body of rod tubing cross section resistance moment, realizes flange connections two-fold bending resistance effect; But the relative position of welding gasket secure liner pipe and flange on the internal lining pipe guarantees the effective of reinforcement measure.

Adhering to bar processing and fabricating technology is common prior art, by industry technical personnel is grasped.

The essential accessory that adheres to bar is for having sharply tuned adjustment leading screw, connecting conehead, internal lining pipe, optional accessory is that the length body of rod that meets modulus is (when whole rod member is used, the integral body that connects conehead, adjustment leading screw composition is the essential accessory that connects tower machine and building, what and length of the body of rod are to determine with the demand at scene, on-the-spot words that need even can be without the body of rod, when being optional accessory, internal lining pipe is essential, because being applied to that I haven't seen you for ages and a flange occurring of the whole body of rod connects, all must add an internal lining pipe) as long as flange bonded assembly place occurs; The adjusting range of essential accessory and body of rod length meet modulus, form by connecting conehead, adjustment leading screw, pipe and flange; Optional number of fitting parts is decided on user's request, but each section body of rod length should be the integral multiple of adjusting the leading screw adjusting range, is made up of pipe and flange; All accessories are steel spare.

Principle of work

Adhere to the stressed ultimate limit state of bar during according to tower machine normal operation, by mechanical analysis with calculate the specification determine to adhere to bar, flange, high strength bolt and internal lining pipe, when adhering to bar mobile jib length, adhere to bar stability and be better than the bar that adheres under the limiting length less than limiting length; Determine each compound rod length according to statistics; Determine the flange position of weld according to the structure of adhering to bar, for the relative position of secure liner pipe and flange vertically is provided with pad in the centre at internal lining pipe; Flange with take firm twice weld seam being connected of other members; Flange connects is convenient to adhere to bar dismounting and quality inspection, realizes that turnover is used easily.

Compared with prior art, the adjustable tubular type of building tower captain degree of the present utility model adheres to the beneficial effect that bar has and is: can be according to the requirement of camp site, be implemented in than adjustable in the length scope, can satisfy the camp site needs.Have simple in structure, be easy to processing, on-site installation is simple, easy to use, can realize that turnover uses, transportation is convenient, remarkable in economical benefits; Connection mode is the flange high strength bolt and connects, and the quality of connection inspection method is simple, and quality is easy to guarantee; Advantages such as the easy loss parts that adhere to bar are high strength bolt, and the use limitation of bar is adhered in traditional relatively special use, and waste of material is minimum.
