Abstract

The utility model discloses a basic ring anti-loosening fixing device, which comprises load releasing units and a fixing steel rope, wherein two or more than two load releasing units are uniformly distributed on the outer tube wall of a basic ring, the two or more than two load releasing units and the outer tube wall of the basic ring are fixed in a winding way by the fixing steel rope through grooves, and the fixing steel rope and the load releasing units which are fixed together are buried into basic concrete. The basic ring anti-loosening fixing device has the advantages that two or more than two load releasing units which are fixed together are arranged on the outer tube wall of the basic ring, and when the basic ring is about to generate irregular swinging through receiving the wind load effect at the upper part of a fan, the absorbed load is fast dispersed and released into the surrounding basic concrete far away from the basic ring through the load releasing units, so the local pressure damage possibility caused by excessive local pressure stress of the concrete around the basic ring is effectively prevented, in addition, the pressure stress fatigue stress amplitude received by the concrete around the basic ring can be reduced to a great degree, and the fatigue damage of the concrete around the basic ring can be prevented.

Description

The locking fastening devices of a kind of discharge ring

Technical field

The utility model relates to the locking fastening devices of a kind of discharge ring.

Background technology

At present, discharge ring is a kind of common cylinder type that wind-power generating unit tower is connected with concrete foundation, determines diameter, wall thickness and the buried depth of discharge ring according to wind power generating set upper load.Discharge ring provides a kind of syndeton that is easy to production, is convenient to installation on being to a great extent, top is connected with blower fan tower barrel by bolt, and bottom is embedded in concrete foundation.Due to the swing that meeting produces all directions, different amplitudes under wind action of blower fan top impeller, this swing meeting swings together with discharge ring, wherein amplitude of fluctuation maximum on prevailing wind direction, under this kind long-term reciprocal and irregular swing, contact between discharge ring and concrete foundation is connected by progressive failure, between discharge ring and concrete foundation, produce relative displacement, so discharge ring barrel and discharge ring lower flange can apply periodically compressive stress to concrete foundation, make the concrete generation office being in contact with it crush bad and fatigue failure.

Utility model content

The utility model object is to overcome above defect, provide one can stop the random swing of discharge ring, prevent that discharge ring and concrete foundation from producing relative displacement, around base concrete is stressed to improve discharge ring, thereby avoids concrete generation office to crush the locking fastening devices of discharge ring of bad and fatigue failure.

The technical solution of the utility model is: the locking fastening devices of a kind of discharge ring, it comprises load releasing unit and fixing tightwire, described discharge ring outer tube wall is laid with two or more load releasings unit, described load releasing unit comprises upper junction plywood, load releasing diagonal brace, bottom load releasing flat board, load releasing diagonal brace upper end and upper junction plywood are fixed together, the lower end of load releasing diagonal brace and bottom load releasing flat board are fixed together, the inner surface of upper junction plywood is the fluted column face matching with discharge ring outer tube wall, the external surface of upper junction plywood is provided with two or more groove, fixing tightwire is fastened two or more load releasing unit by groove with discharge ring outer tube wall together with, in the load releasing unit being fixed together and fixing tightwire buried foundation concrete.

In order better to make upper junction plywood contact with discharge ring outer tube wall, described upper junction plywood inner surface surrounding all needs chamfered.

Concentrated in order to prevent upper junction plywood and discharge ring outer tube wall contact stress, the elastic cushion block with certain rigidity is set between upper junction plywood and discharge ring outer tube wall.

In order to increase the contact area between load releasing unit and base concrete, the appearance of described load releasing unit is matsurface.

The appearance of described load releasing unit is provided with the steel plate or the reinforcing bar that increase surface area.

Technique effect of the present utility model is, owing to being provided with the load releasing unit that two or more are fixed together at discharge ring outer tube wall, thereby load releasing unit and discharge ring form efficient integral, when discharge ring is subject to blower fan top wind action wish that random swing occurs, the load releasing unit of close contact takes the lead in absorbing the load that discharge ring produces because of swing with it, by load releasing unit, rapidly the load of absorption is disperseed to be discharged into away from discharge ring base concrete around, thereby effectively prevent the possibility that discharge ring surrounding concrete is bad because the excessive generation of local compressive stress office crushes, and largely reduce the compressive stress Fatigue Stress Amplitude that discharge ring surrounding concrete is subject to, prevent the fatigue failure of discharge ring surrounding concrete.

Accompanying drawing explanation

Fig. 1 is example structure schematic diagram of the present utility model;

Fig. 2 is the utility model embodiment load releasing block construction schematic diagram.

The specific embodiment

Below in conjunction with drawings and Examples, the utility model is further illustrated.

With reference to accompanying drawing 1, accompanying drawing 2, the locking fastening devices of a kind of discharge ring, it comprises load releasing unit 6 and fixing tightwire 7, at discharge ring 2 outer tube walls, is laid with load releasing unit 6, the appearance of described load releasing unit 6 is matsurface.Described load releasing unit 6 comprises upper junction plywood 1, load releasing diagonal brace 4, bottom load releasing flat board 5, and load releasing diagonal brace 4 upper ends and upper junction plywood 1 are fixed together, and the lower end of load releasing diagonal brace 4 and bottom load releasing flat board 5 are fixed together.The inner surface of upper junction plywood 1 is the fluted column face matching with discharge ring 2 outer tube walls, and upper junction plywood 1 inner surface surrounding all needs chamfered.The elastic cushion block 3 with certain rigidity is set between upper junction plywood 1 and discharge ring 2 outer tube walls.The external surface of upper junction plywood 1 is provided with groove 8, fixing tightwire 7 is fastened load releasing unit 6 by groove 8 with discharge ring 2 outer tube walls together with, in the load releasing unit 6 being fixed together and fixing tightwire 7 buried foundation concrete.

Owing to being provided with the load releasing unit 6 being fixed together at discharge ring 2 outer tube walls, thereby load releasing unit 6 forms efficient integral with discharge ring 2, when discharge ring 2 is subject to blower fan top wind action wish that random swing occurs, the load releasing unit 6 of close contact takes the lead in absorbing the load that discharge ring 2 produces because of swing with it, by load releasing unit 6, the load of absorption is disperseed to be discharged into rapidly away from discharge ring 2 base concrete around, thereby effectively prevent the possibility that discharge ring 2 surrounding concretes are bad because the excessive generation of local compressive stress office crushes, and largely reduce the compressive stress Fatigue Stress Amplitude that discharge ring 2 surrounding concretes are subject to, prevent discharge ring 2 surrounding concrete fatigue failures.

Be more than a kind of embodiment of the present utility model, a preferred demonstration example.The scope of the utility model application request protection has more than and is limited to described embodiment.All and technical scheme the present embodiment equivalence all belongs to protection domain of the present utility model.
