specific implementation method
Be described further below in conjunction with the mode of priority of accompanying drawing to the technical scheme that the spiral elevating fire truck of the utility model adopts:
Its static structure refers to Fig. 1, 2, as shown in the figure, the spiral elevating fire truck of the utility model is by motor (3-5), double end gear (3-2), bearing support (3), panoramic table (8), lifting tube (4), spline core (5), truss (6), elevator scoop (7) forms, wherein: under bearing support (3) is fixed on panoramic table (8), lifting tube (4) is arranged on panoramic table (8), spline core (5) is enclosed within lifting tube (4), plunger tip welded truss (6), end core is connected with the spline core bracket (3-1) in bearing support, lifting tube top cylinder (4-1) welded truss (6), elevator scoop (7) is arranged on truss (6), power motor (3-5) device is in panoramic table (8) lower supporting frame, rotor gear engagement double end gear (3-2) is through cylinder (4-2) at the bottom of panoramic table (8) engagement lifting tube.
Its panoramic table (8) selects pivoting support to make critical piece, and effect is: pivoting support can bear larger axial force and tilting moment, and assembles very convenient.
Its bearing support top arranges spline core bracket (3-1), bottom arranges machine operation frame (3-4), spline core bracket other (3-1) arranges double end gear (3-2) bracket, reason is: spline core (5) is enclosed in lifting tube (4) internal diameter, lifting tube (4) is arranged on panoramic table (8), spline core (5) diameter is less than lifting tube (4) diameter, lifting tube (4) diameter is less than again panoramic table (8) diameter, machine operation frame (3-4) diameter is greater than lifting tube (4) diameter, bracket due to these different-diameters all belongs to a bearing support together, be interconnected, not interrupted for ensureing that lifting tube (4) rotates, each element diverse location, different-diameter can cooperatively interact, Each performs its own functions, double end gear (3-2) just must be taken into account at two, two is got in touch with, play connection pivotal role.
Its lifting tube (4) profile design is straight tube shape, reason is that straight tube shape profile mainly considers that cylinder can spiral lifting, other shapes can not rotate, length is identical is because lifting tube (4) can be overlapped into one section of tube length degree after declining, up-small and down-big is also cylinder necessary condition overlapping with cylinder, takes into account whole lifting process stability simultaneously.
Its lifting tube (4) internal and external threads is covered with full cylinder, screw thread is not had along sub-fraction at the bottom of internal diameter, internal diameter top is less than all the other part diameters along the sub-fraction diameter of thread, all the other part diameters are greater than along the sub-fraction length diameter of thread at the bottom of external diameter, object is: after every lifting tube rotates and rises, straight-cylindrical screw thread may rotate and continue, generation cylinder and cylinder disconnect, internal diameter top is less than at the bottom of all the other part diameters and external diameter along the sub-fraction diameter of thread and is greater than all the other part diameters along the sub-fraction length diameter of thread, most length external screw thread of next lifting tube (4) can be made to coincide upper lifting tube (4) internal diameter top along sub-fraction screw thread, the bottom diameter of the upper most length of lifting tube (4) of coincideing along sub-fraction length screw thread at the bottom of next lifting tube (4) external diameter, this structure, both can ensure that lifting tube (4) rose smoothly and declines, add brake to again lifting tube (4), after lifting tube (4) rises completely, the slightly large sub-fraction screw thread of next lifting tube (4) diameter withstands a slightly little a part of screw thread of lifting tube (4) internal diameter, what define between cylinder with cylinder is overlapping, there is no screw thread along sub-fraction at the bottom of internal diameter, when being and declining to lifting tube (4), increase brake, after preventing next lifting tube (4) decline, return body upwards through edge at the bottom of a upper lifting tube.
Its end cylinder (4-2) only has internal thread, does not have external screw thread, and top cylinder (4-1) only has external screw thread, does not have internal thread, is that external screw thread accepts other power passed over because internal thread is that power is passed to other cylinders between cylinder and cylinder.After end cylinder (4-2) accepts the moment that motor passes over, without the need to accepting other power again, so do not have external screw thread, top cylinder (4-1) does not need again power to be passed to other cylinders, so do not have internal thread.
Become shirt rim (4-3) along bending aft-loaded airfoil at the bottom of its end cylinder, shirt rim (4-3) is erected on panoramic table (8), is because panoramic table (8) main body energy load-bearing whole lifting tube (4) weight, allows lifting tube (4) at the upper smooth rotation of panoramic table (8).
Its end cylinder (4-2) length is slightly longer than other cylinders, and reason is coincide along spur gear and double end gear (3-2) at the bottom of end cylinder (4-2) internal diameter, and lifting tube (4) needs to reserve this segment length that end cylinder (4-2) is engaged with double end gear (3-2) after shrinking.
Its double end gear (3-2) return pulley gearing motor, cylinder (4-2) internal diameter spur gear at the bottom of top wheel engagement lifting tube, the axle in the middle of gear is arranged in the other axis hole of spline core bracket, needs flexible rotating.
Circular or the polygon circle of its spline core (5) external diameter hexagon, be in order to fixed supporting frame does not turn, round edge shape is more, and it is stronger to clamp down on strength.
The making of its spline core top round edge hold-doun nut (5-2) and from bottom to up three point of one place's planing strip slot (5-3), in order to spline core (5) is after rising with lifting tube (4), a core and another core is prevented to disconnect, when every spline core (5) is risen, strip slot embeds in nut, because nut head is thinner, spline core (5) lifting can not be affected.
Its dynamic structure, in the preferred embodiment implemented, in practicality, when fire fighting truck sails to incident place, when needing ascend a height fire extinguishing or impose rescue, start work drive motor, rotor engagement double end gear (3-2) return pulley rotates, coaxial top wheel drives cylinder (4-2) at the bottom of lifting tube to do equidirectional rotation, turning moment is passed by cylinder by lifting tube (4), because top cylinder (4-1) is welded by truss (6), truss (6) is fixed by spline core (5) again, the power that end cylinder (4-2) is uploaded cannot rotate by driving truss (6), lifting tube (4) just along screw thread by cylinder upwards, each straight tube is given to upper level straight tube power after oneself external screw thread has rotated, like this, push up the truss (6) of (4-1) on cylinder, elevator scoop (7) also rises thereupon, after completing the height of needs, the truss (6) on top cylinder (4-1) is needed fire extinguishing by panoramic table (8) aligning or is needed the direction imposing rescue, starts water cannon to put out a fire or is rescued in elevator scoop (7) approaching rescue place.
