Abstract
The invention belongs to a heat flow guide technique and particularly discloses a heat flow guide passage system for a suspended lifting platform. The heat flow guide passage system for the suspended lifting platform comprises a fixed flow guide passage. The fixed flow guide passage is a hollow rectangular solid structure. A central through hole is arranged in the center of the fixed flow guide passage. A fixed flow guide casing is arranged on the fixed flow guide passage. The heat flow guide passage system for the suspended lifting platform additionally comprises a working platform. A circular hole is arranged on the working platform. A main shaft is fixedly arranged below the working platform. A movable flow guide passage is arranged in the main shaft. The lower end of the movable flow guide passage is arranged in the fixed flow guide casing. By designing the fixed flow guide passage and the movable flow guide passage, flame heat is divided into a movable flow guide part and a fixed flow guide part to flow out. Therefore, not only can the performance index of a product be guaranteed, but also the suspended lifting platform can work normally and the reliability is higher. Moreover, since a high-performance heat insulating material, i.e. a fireproof high-temperature-resistant asbestos woven fabric is used, the heat is further prevented from damaging the parts of the platform through heat transfer or radiation and the reliability of equipment is further guaranteed.

According to understanding in Cha Xin and industry, in hoistable platform conventional products, if flow-guiding channel is not established at the middle part of worktable, hot-fluid cannot be derived at present, very easily test product and equipment are damaged.
As shown in Figure 1, the suspended lifting platform of prior art generally comprises base 103, electric cylinder 104 and lifting frame 106.Leveling lower margin 102 is installed in base 103 bottoms, can carry out leveling to platform stage body, and base 103 bottoms are also provided with universal caster wheel 101 simultaneously, can integrated moving suspended lifting platform.Electric cylinder 104 is fixed on base 103 sidewalls of suspended lifting platform, and electric cylinder 104 push rods are connected with lifting frame 106.Line slideway 105 is installed on lifting frame 106, and line slideway 105 slide blocks are fixed on the sidewall of platform base 103.The elevating movement of suspended lifting platform makes lifting frame 106 rise or decline by electric cylinder 104 as topworks.
Summary of the invention
The object of the present invention is to provide a kind of heat flow guide passage system that can be used in suspended lifting platform, it can be derived the hot-fluid in suspended lifting platform, guarantees the security of detected product and equipment.
Technical scheme of the present invention is as follows:
For a heat flow guide passage system for suspended lifting platform, it comprises determines flow-guiding channel, described determines the rectangular structure that flow-guiding channel is hollow, and its center is provided with central through hole; On flow-guiding channel, be provided with and determine flow guiding casing tube determining, the described heat flow guide passage system for suspended lifting platform also comprises a worktable, and this worktable is provided with circular hole, and worktable below is fixed with main shaft; In main shaft, be provided with moving flow-guiding channel, its lower end is positioned at this and determines flow guiding casing tube.
At the above-mentioned heat flow guide passage system for suspended lifting platform: the described flow-guiding channel inside center of determining is provided with a cone, and concentric with central through hole; Determine the lower plane of flow-guiding channel by becoming two inclined-planes of 170 °～200 ° of angles to form.
At the above-mentioned heat flow guide passage system for suspended lifting platform: the described cylindrical hollow ring of moving flow guiding casing tube, its outer wall is provided with flange, and flange is fixedly connected with set nut with main shaft lower end.
At the above-mentioned heat flow guide passage system for suspended lifting platform: described outer of determining flow-guiding channel is fixed with platform support.
At the above-mentioned heat flow guide passage system for suspended lifting platform: described determine flow-guiding channel, determine flow guiding casing tube and moving flow-guiding channel outer wall attaches heat-barrier material fireproof high-temperature resistant asbestos woven cloth.
Remarkable result of the present invention is: by designing, determine flow-guiding channel and moving flow-guiding channel, make flame heat regulating be divided into two parts and flow out, a part is water conservancy diversion, and another part is to determine water conservancy diversion.So, guarantee the performance index of product, can make again suspended lifting platform normally work, there is higher reliability.Use high-performance insulation material fireproof high-temperature resistant asbestos woven cloth simultaneously, further avoided heat to make platform damage of components by conduction or radiation, more guaranteed the reliability of equipment.

Embodiment
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
As shown in Figure 2, on circular worktable 6, process circular hole, the through hole of processing 220mm in the middle of the present embodiment, the inwall of main shaft 5 is stepped, and its minimum diameter is 210mm.Worktable 6 is fixedly mounted by screw and main shaft 5.
Moving flow-guiding channel 4 is columned hollow ring, and its first half is sleeved in main shaft 5, is installed with flange 8 on its outer wall, and this flange 8 is fixedly connected with set nut 7 with the lower end of main shaft 5.In the present embodiment, moving flow-guiding channel 4 internal diameters are 203mm, adopt the can manufacturing of 1mm corrosion resistant plate to manufacture, lightweight, guarantee that flame heat regulating can not exert an influence to it.
The latter half of moving flow-guiding channel 4 is positioned at determines flow guiding casing tube 3, determines flow guiding casing tube 3 and is cylindric, and in the present embodiment, the internal diameter of determining flow guiding casing tube 3 is 220mm, and its lower end is fixed on central through hole 8 places that determine flow-guiding channel 1.Described determines flow-guiding channel 1 for the rectangular structure of hollow, its lower plane is by becoming two inclined-planes 11 of 170 ° of angles to form, and center has the central through hole 9 of 220mm diameter, and periphery is processed with threaded hole, determine a cone 10 of inside fixed installation of flow-guiding channel 1, and concentric with central through hole 9.Determining the outer fixed installation platform base 2 of flow-guiding channel 1, in the side bottom of platform base 2, pass through M4 screw and determine flow-guiding channel 1 fixing.Described determine flow-guiding channel 1 and can effectively guarantee that flame type of thermal communication crosses after the shunting on cone 10 and two inclined-planes 11, rapidly hot-fluid is discharged.
At moving flow-guiding channel 4 outer walls, determine flow guiding casing tube 3 outer walls and determine flow-guiding channel 1 outer wall to attach heat-barrier material---fireproof high-temperature resistant asbestos woven cloth, can effectively guarantee the normal work of other parts of platform, and guarantee, in suspended lifting platform lifting process, to avoid moving interference.
When test product is arranged on suspended lifting platform lifting frame 106, the product point fire hot-fluid that jets out flames, first by worktable 6 centers, then, through the endoporus of moving flow-guiding channel 4, now worktable is in fast drop course.By determining flow guiding casing tube 3 endoporus, heat is imported and determines flow-guiding channel 1, through cone and water conservancy diversion inclined-plane, flame hot-fluid is derived completely.
