At present, the pipelines such as air feed, water supply mostly are lifting, namely are provided with for the rigid mount that hangs pipeline in the building of needs laying pipeline, and device for cleaning pipeline is crossed lifting or clamping tool is suspended on the rigid mount, forms pipeline with this.The existing rigid mount that is used for the suspension pipeline is generally I-beam section and makes, and the lifting part that is used for the lifting pipeline is take-up clip.
The structure of above-mentioned take-up clip comprises the fixture block with tiger’s jaw, be equipped with on the fixture block for the fastening bolt that edge under the I-beam section is clamped in the tiger’s jaw of fixture block, in the fixture block, the part that contacts above that is positioned at edge under tiger’s jaw top and the I-beam section is the upper folder section of fixture block, be positioned at part that tiger’s jaw below is used for installing fastening bolt and be lower folder section, the centre portion that connects upper folder section and lower folder section in the fixture block is middle interconnecting piece.
Take-up clip clamps I-beam section, and rigid pipe (can be thread rod or steel rope etc.) the suspension pipeline by being connected with fixture block, the weight of pipeline all is applied on the fixture block of take-up clip, maximum shear stress bears with the knuckle place that is connected of middle interconnecting piece in upper folder section in the fixture block, when the weight of pipeline is larger, in the fracture of above-mentioned knuckle place, there is potential safety hazard in fixture block easily.In order to prevent that above-mentioned situation from occuring, people can select the larger take-up clip of model, like this, not only waste the making material of take-up clip, and for the user, have increased the cost of engineering construction.
Summary of the invention
The utility model for solve the technical matters that exists in the known technology provide a kind of simple in structure, reasonable in design, save make material and cost, lightweight, resistance to tension strong, the large pipeline lifting take-up clip of weight that can carry.
The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is: a kind of pipeline lifting take-up clip, comprise fixture block and the fastening bolt that is installed on the fixture block, described fixture block is by upper folder section, lower folder section and connect folder section and the middle interconnecting piece of lower folder section forms, described upper folder section, lower folder section and middle interconnecting piece connect and compose the tiger’s jaw of described fixture block, described fastening bolt is installed in the lower folder section, it is characterized in that: have two knuckles on the described tiger’s jaw, the knuckle place on described tiger’s jaw top is along the thickness of the broken line direction thickness greater than described middle interconnecting piece bottom and lower folder section.
The utility model can also adopt following technical scheme:
Two knuckles of described tiger’s jaw are knuckle, and the knuckle place on described tiger’s jaw top is along the thickness of the axial thickness of fillet greater than described middle interconnecting piece bottom and lower folder section.
Be the transition inclined-plane on the described middle interconnecting piece between two parts of different-thickness.
The angle number of degrees between the bottom surface of the transition line on described transition inclined-plane and described lower folder section are 1 °-2 °.
Described lower folder section is provided with connecting bore, and described connecting bore runs through middle interconnecting piece.
On the described fastening bolt jam nut is installed.
Advantage and the good effect that the utlity model has are: because the utility model adopts as above technical scheme, namely increase the thickness of the easy breaking part of take-up clip, and the thickness of other position remains unchanged in the take-up clip, so can be when guaranteeing to increase the take-up clip resistance to tension, strengthening the weight ability to bear, save to greatest extent and make material and cost of manufacture, for the user, can reduce the cost of engineering construction.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1.
Among the figure: 1, fixture block; 1-1, upper folder section; 1-2, lower folder section; 1-3, middle interconnecting piece; 1-4, tiger’s jaw; 1-5, connecting bore; 2, fastening bolt; 3, jam nut.
The specific embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and cooperate accompanying drawing to be described in detail as follows:
See also Fig. 1 and Fig. 2, a kind of pipeline lifting take-up clip.Comprise fixture block 1, fixture block 1 is the base portion of take-up clip, and fixture block 1 is integrated the metal piece of casting, and in the present embodiment, fixture block 1 is by the malleable iron casting.Fixture block can be divided into three parts according to different stressing conditions and function, comprise the 1-1 of folder section, the lower folder 1-2 of section and the middle interconnecting piece 1-3 that is connected the 1-1 of folder section and the lower folder 1-2 of section.Consist of the tiger’s jaw 1-4 of fixture block 1 between the above-mentioned upper folder 1-1 of section, the lower folder 1-2 of section and the middle interconnecting piece 1-3.Be equipped with for other connecting element (present embodiment, " other connecting element " is the lower edge of I-beam section) is clamped in the fastening bolt 2 among the tiger’s jaw 1-4 at the lower folder 1-2 of section.The bending part of above-mentioned tiger’s jaw 1-4 is round-corner transition, and the knuckle place that is connected of namely going up the 1-1 of folder section and middle interconnecting piece 1-3 is round-corner transition; The lower folder 1-2 of section is round-corner transition with the knuckle place that is connected of middle interconnecting piece 1-3.Fixture block 1 is when installing and using, and the above-mentioned upper folder 1-1 of section and middle interconnecting piece 1-3 are connected the easiest fracture in knuckle place.
In order to increase the take-up clip resistance to tension, to strengthen the weight ability to bear, make that the 1-1 of folder section and middle interconnecting piece 1-3's be connected not easy fracture of knuckle place, save to greatest extent again simultaneously the making material of fixture block 1, in the utility model, the knuckle place that makes tiger’s jaw 1-4 top along the axial thickness of fillet greater than the bottom of middle interconnecting piece 1-3 and the thickness of the lower folder 1-2 of section, be the thickness of easy fracture place knuckle on the single increase fixture block 1, with this dual purpose that realizes saving material and increase intensity.
Pass through chamfered transition between two parts of the upper different-thickness of middle interconnecting piece 1-3.In addition, make things convenient for depanning in order to make fixture block 1 when casting, the angle number of degrees between the bottom surface of the transition line on transition inclined-plane and the lower folder 1-2 of section are 1 °-15 °, make fixture block 1 have certain pattern draft with this.In the present embodiment, the angle number of degrees that cross between the bottom surface of the transition line on inclined-plane and the lower folder 1-2 of section are 2 °.
The lower folder 1-2 of section is provided with the connecting bore 1-5 that runs through middle interconnecting piece, and connecting bore 1-5 is used for being connected with the rigid pipe that hangs pipeline.Jam nut 3 is installed on the fastening bolt 2, guarantees that fastening bolt 2 is not loosening, make the take-up clip reliable grip on the lower edge of I-beam section.
