Abstract
The utility model discloses a displacement compensation supporting mechanism for rotary sealing structure, which comprises a mechanism base and an apparatus assembling platform. The apparatus mechanism base is a cavity where an elastic component is arranged, and the two ends of the elastic component respectively abut against the bottom surface of the cavity and the lower surface of the apparatus assembling platform. A plurality of holes are arranged on the circumference of the mechanism base, a guide sleeve is arranged inside each hole, the apparatus assembling platform is provided with bolt holes in correspondence with the holes of the mechanism base, and guide screws are connected with the bolt holes after penetrating the guide sleeves to enable the apparatus assembling platform to make slight movement relative to the mechanism base. The elastic component can be a spring, or a hydraulic cylinder or a gas cylinder. As the elastic component is adopted for supporting the mechanism assembling platform, the displacement or deformation of the apparatus body can be transferred to the elastic component through the apparatus assembling platform and be compensated through the elastic deformation of the elastic component, thereby ensuring normal running of the apparatus, prolonging normal production period and reducing manufacture cost.
Description
Technical field
The utility model relates to a kind of load carrier that need to be used to bit shift compensation, particularly a kind of bit shift compensation load carrier that is used for rotary seal structure.
Background technique
When needing to keep relative position or sealing between a kind of rotation or straight line motion body and the fixture, because the deadweight of equipment or the distortion of thermal distortion and wearing and tearing or equipment can cause the change of relative position between moving body and the fixture or the inefficacy of sealing, need the variation that a kind of device compensates this displacement this moment.In the dry coke quenching equipment of metallurgy industry, the rotary seal valve of existing coke discharging device and coke discharging pipeline and installation basis are and are rigidly connected, there is not the displacement damping device to absorb owing to worst hot case, expand with heat and contract with cold and distortion that equipment self-weight produces, so that rotary valve is yielding for ellipse causes the rotating seal wearing and tearing, causes valve body and the seal failure of top seal device and the nitrogen leakage.So in dry coke quenching equipment, the rotary seal valve of coke discharging device needs often to detect, maintenance, changed in case damage the long period that needs to stop production, will have a strong impact on normal production.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of bit shift compensation load carrier that is used for rotary seal structure, during the change of relative position, can compensate this displacement between moving body and fixture.
For solving the problems of the technologies described above, the utility model is used for the bit shift compensation load carrier of rotary seal structure, comprise device pedestal, be installed in the equipment mountion plate of device pedestal top, in the device pedestal for cavity and lay elastic element, the two ends of elastic element are resisted against respectively on the lower surface of cavity floor and equipment mountion plate, on the close periphery of device pedestal, have the hole of some, guide sleeve is installed in the hole, have on the equipment mountion plate with device pedestal on the corresponding screw in hole, guide spiro rod passes described guide sleeve and is connected with screw, and the equipment mountion plate of making relatively device pedestal move up and down; Elastic element can adopt spring; Also can adopt oil hydraulic cylinder or cylinder.
Because being used for the bit shift compensation load carrier of rotary seal structure, the utility model adopts elastic element support apparatus mountion plate, when apparatus body has displacement or distortion, this distortion or displacement are passed to elastic element by the equipment mountion plate, resiliently deformable by elastic element compensates above-mentioned displacement or distortion, and between device pedestal and equipment mountion plate, be provided with guide spiro rod and guide sleeve, displacement or deformation-compensated directivity have been guaranteed, therefore the utility model bit shift compensation load carrier of being used for rotary seal structure has been guaranteed the normal operation of equipment, prolong the cycle of ordinary production, reduced cost of production.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 is a kind of schematic representation that is used for the bit shift compensation load carrier of rotary seal structure of the utility model
Embodiment
Fig. 1 is a kind of schematic representation that is used for the bit shift compensation load carrier of rotary seal structure of the utility model, this bit shift compensation load carrier comprises device pedestal 4, the equipment mountion plate 5 of device pedestal 4 tops, in the device pedestal 4 for cavity and lay elastic element 1, elastic element 1 two ends are respectively against cavity floor and equipment mountion plate 5 lower surfaces, on device pedestal 4 close peripheries, have the hole of some, guide sleeve 3 is installed in the hole, on the equipment mountion plate 5 with the corresponding screw that has in the hole on the device pedestal 4, guide spiro rod 2 passes described guide sleeve 3 and is connected with screw, and make equipment mountion plate 5 relatively device pedestal 4 move up and down;
Device pedestal 4 is connected with basic rigidity by forms such as bolt or welding, equipment mountion plate 5 is rigidly connected by forms such as bolt or welding and apparatus body 6, when apparatus body 6 has upper and lower displacement or distortion because of the influence that is subjected to various operating modes at work, this displacement or distortion are passed to elastic element 1 by equipment mountion plate 5, resiliently deformable by elastic element 1 compensates above-mentioned displacement or distortion, in order to guarantee displacement or deformation-compensated directivity, guide spiro rod 2 moves along direction initialization in guide sleeve 3, guarantee the direction of displacement of equipment, also guaranteed a kind of like this guide function between equipment mountion plate 5 and the device pedestal 4 simultaneously.
According to the working condition of apparatus body and the weight situation of apparatus body, elastic element 1 can be selected butterfly spring group, cylindrical spring, air spring etc. for use, also can adopt load-bearing compensating elements such as oil hydraulic cylinder, cylinder to be used as elastic element equally if needed; According to the apparatus body situation, this displacement compensation load carrier can be formed one group by a cover or this device of some covers and jointly equipment be played compensation load-bearing effect.
