Abstract

The utility model relates to a bracket of floating type bearing seat for greenhouse curtain-drawing system, and belongs to the technical field of mechanical structure, transmission and fastening of greenhouse curtain-drawing system. The bracket comprises a chamfered rectangular thin steel plate having a middle square hole with two semicircular ends; and a flat-head triangle with multiple symmetric large/small holes on its long/short edges, a notch on the outer side in the middle of the long edge, and central long waist-shaped hole. The crossing points of two flat-head triangles with straight edge are first right angle bending sites. The near center sites of two notches are second right angle reverse bending sites. Thus, a holey square protruded sheet of two protruded platforms having middle isolation round hole is constituted. The inventive bracket structure tightens the floating bearing seat via wire rope from four different directions; has no limitation of support point and bracket position, and flexible installation; and can be used for reconstructing old greenhouse and building new greenhouse.

Description

A kind of support that is used for greenhouse draw curtain system floating type bearing block

Technical field

The frame for movement, transmission and the tightening technology field that belong to greenhouse draw curtain system.

Background technology

At present, the bearing block of the indoor heavy curtain of domestic greenhouse and other system substantially all is installed on pillar, beam or other supporters, with the rotation of supporting shaft; The defective of this mode maximum is to be necessary for bearing block to seek or be provided with " basic point " that a bearing connects, for newly-built greenhouse etc., these basic point ratios are set to be easier to, but for the transformation in existing greenhouse etc., owing to there is not the forethought setting, the spacing of bearing block is often greater than the rational spacing of the power transmission shaft (as: power transmission shaft of D50, the bearing block spacing≤5.0m), in this case, the cost that increases the strong point is very big, be subjected to the influence of other equipment simultaneously, the technical difficulty of setting up is also very high, therefore often adopt the way that increases shaft diameter in actual the use, so not only increased cost, also increased the load clicked and with the difficulty of other coordinative composition of equipments, in the engineering that some greenhouse is transformed, it is excessive and to produce axle vertical crooked the axle support distances to have occurred, situations such as motor burns out, thus had influence on the normal use of greenhouse draw curtain system.

Summary of the invention

The utility model provides a kind of use flexible, and cost is low, also can be used for a kind of support that is used for greenhouse draw curtain system floating type bearing block of existing greenhouse transformation.

The technical scheme that the utility model is taked is:

The rectangle sheet metal of chamfering all around, the centre is that two ends are the oblong aperture of drawing back of semicircle, there is a symmetrical roundlet arc at the slotted hole middle part, there are 4 macropores of symmetry on long limit, minor face has 6 apertures of symmetry, there are the two rectangular breach of being with of symmetry in the outside, middle part, long limit, there is the tack triangle in long waist shaped hole at the center in two breach, two tack triangles and straight flange intersection point place, it is the first right angle bending part, two nearly centers of rectangular breach are inverse bending place, second right angle, and band was separated two protruding platforms of circular holes in the middle of two symmetrical right angle bendings constituted one, and both sides are respectively with side's lug with holes of the support plate in three holes.

Good effect behind enforcement the utility model:

Owing to adopt bearing bracket structure of the present utility model, its fixed form is not and (the electric welding that is rigidly connected of fixing bearing point, bolt etc.), but adopt steel wire rope from four different direction tensions this " floating bearing seat ", make it not to be subjected to the restriction of the strong point and the restriction of support position, as long as on the same horizontal plane the fixedly place of steel wire rope is arranged on every side, just can fix " floating bearing seat ", broken away from the restriction that bearing block in the past rigidly fixes, significantly reduced workload to the influence and the repacking of other equipment in the greenhouse, improved the installation quality of work efficiency and system, not only can be used for transforming the engineering in greenhouse, also can be used for newly-built greenhouse engineering.

Embodiment

Now the utility model is described in further detail in conjunction with the accompanying drawings

The making of support comprises definite flat shape, and is planar-formed, operations such as bending.Flat shape is: the rectangle sheet metal of chamfering all around, the centre is that two ends are the oblong aperture of drawing back 3 of semicircle, there is a symmetrical roundlet arc at the slotted hole middle part, there are 4 macropores 1 of symmetry on long limit, minor face has 6 apertures 2 of symmetry, there are the two rectangular breach 4 of being with of symmetry in the outside, middle part, long limit, there is the tack triangle in long waist shaped hole 5 at the center in two breach, two tack triangles and straight flange intersection point place are the first right

angle bending part

6,9, two nearly centers of rectangular breach are inverse bending place, second right angle 7, band was separated two protruding platforms 11,12 of circular holes 10 in the middle of 8 two symmetrical right angle bendings constituted one, and both sides are respectively with side's lug with holes of the support plate in three holes.

Embodiment

With two side's lugs with holes, its support plate is harmonious, four bearings 13 are fixing by four screw-nuts 14 that respectively pass hole 2, system drive axle 15, pass 10, four steel wire ropes 16 of Tab holes, respectively pass four mounting holes 5, be wrapped on four screws 17 that respectively pass hole 1, constitute the bearing block of supporting driving shaft.

Claims

1. support that is used for greenhouse draw curtain system floating type bearing block, the hole that comprises rigid bearing, it is characterized in that: the rectangle sheet metal of chamfering all around, the centre is that two ends are the oblong aperture of drawing back (3) of semicircle, there is a symmetrical roundlet arc at the slotted hole middle part, there are symmetry 4 macropores (1) on long limit, minor face has symmetry 6 apertures (2), there are the two rectangular breach (4) of being with of symmetry in the outside, middle part, long limit, there is the tack triangle in long waist shaped hole (5) at the center in two breach, two tack triangles and straight flange intersection point place are the first right angle bending part (6), (9); Two nearly centers of rectangular breach are inverse bending place, second right angle (7), (8); Band was separated two protruding platforms (11) of circular hole (10), (12) in the middle of two symmetrical right angle bendings constituted one; Both sides are respectively with side's lug with holes of the support plate in three holes.
