Abstract

The invention provides an inserting rod slewing mechanism of a window cleaning machine. The inserting rod slewing mechanism comprises a strut and a cantilever which is arranged at the upper end of the strut, and further comprises an inclined support, wherein a triangular structure is constituted by the inclined support, the cantilever and the upper part of the strut; a fixed stand is arranged on the lower part of the strut; a circle of rotating rollers are arranged on the fixed stand; a rotary tray is welded on the periphery of the strut; the rotary tray is supported by the rotating rollers in the radial direction of the rotary tray; and a rolling bearing is arranged at the bottom of the strut for supporting the strut in a longitudinal direction. The inserting rod slewing mechanism disclosed by the invention, through the adoption of the rolling bearing on all rotating positions, can greatly enhance the convenience of operation.

Description

A kind of inserted link slew gear of window cleaning equipment

Technical field

The present invention relates to a kind of window cleaning equipment, particularly, relate to a kind of inserted link slew gear of window cleaning equipment.

Background technology

In prior art, as shown in Figure 1, the slew gear of inserted link form has two kinds of forms: a kind of be cantilever and pillar is have relative motion, namely cantilever turns round around pillar, at H point, place is provided with sliding bearing, and the lopping revolution roller of more than 3 is housed at M point place, and roller is contained on cantilever mechanism, also around pillar revolution, namely roller is contained in dynamic structure; Another kind is cantilever and pillar is one, namely a big steel pipe is adopted, at M place, rolling bearing is housed, at L place, sliding bearing is housed, owing to adopting the steel pipe of one, outer carry moment of flexure owing to bearing, its corresponding round steel pipe diameter is very large, adopt the bearing in GB without available model or cost very expensive.

Summary of the invention

For the technical problem existed in above-mentioned prior art, the object of this invention is to provide a kind of inserted link slew gear of window cleaning equipment, greatly improve the convenience of operation, lower labour intensity.Extend service life, reduce nonstandard part, alleviate weight of equipment, improve the convenience used comprehensively.

For achieving the above object, the technical solution adopted in the present invention is as follows:

A kind of inserted link slew gear of window cleaning equipment, comprise pillar and be arranged on the cantilever of pillar upper end, also comprise diagonal brace, the upper part of described diagonal brace and described cantilever and described pillar forms a triangular structure, described pillar bottom is provided with fixed frame, described fixed frame is provided with a circle revolution roller, described pillar week side welding single-revolution dish, described revolution roller supports described rotary disk in the radial direction of described rotary disk, described posts bottom is provided with rolling bearing, pillar described in longitudinal bracing.

Described pillar cross section is rectangle.

Described fixed frame comprises a plane and lateral support posts, and described revolution roller is provided with in described plane, described plane offers the circular hole passed for described pillar.

Described revolution roller is set to four.

Described bearing is arranged on bearing block, and described bearing block is welded on described pillar.

Compared with prior art, the present invention has following beneficial effect:

For the revolution of two kinds of forms in prior art, the present invention adopts and uses revolution roller at M place, and L place adopts rolling bearing, and whole pivotal positions are all the forms of applying rolling bearing, greatly improve the convenience of operation.

Contrast the first form former, the invention solves eminence H point in the first form and safeguard tired energy, because its revolution roller is contained in dynamic structure, excesssive gap during relative motion, the problem of the shortening in service life of equipment.

Contrast former the second form, to the invention solves in the second form M place rolling bearing size very large, be often the ball base of special processing, add non-standard and cost, and there is no the precision of commodity part in enormous quantities and quality stability is good, the problem of structure bulky.

Accompanying drawing explanation

By reading the detailed description done non-limiting example with reference to the following drawings, other features, objects and advantages of the present invention will become more obvious:

Fig. 1 is the slew gear schematic diagram of prior art;

Fig. 2 is the structural representation of slew gear of the present invention;

Fig. 3 is the front view of Fig. 1;

Fig. 4 be Fig. 3 along A-A to profile;

Fig. 5 is the partial enlarged drawing at M place in Fig. 3;

Fig. 6 is the partial enlarged drawing at L place in Fig. 3.

Detailed description of the invention

Below in conjunction with specific embodiment, the present invention is described in detail.Following examples will contribute to those skilled in the art and understand the present invention further, but not limit the present invention in any form.It should be pointed out that to those skilled in the art, without departing from the inventive concept of the premise, some distortion and improvement can also be made.These all belong to protection scope of the present invention.

Figure 1 shows that the slew gear of inserted link form in prior art.

Shown in Fig. 2-Fig. 6, the inserted link slew gear of window cleaning equipment provided by the present invention, the upper part comprising cantilever 1, diagonal brace 2 and pillar 3 forms a stable triangle structure.Cantilever 1 and pillar 3 are formed as one.One four, circle revolution roller 5 is arranged on the fixed frame 4 of pillar lower part setting.Fixed frame 4 comprises horizontal plane part 40 and vertical support post 41 two parts.Horizontal plane part 40 is provided with revolution roller 5, and the centre position of horizontal plane part 40 offers the circular hole 42 that pillar 3 can be made to pass.

In the embodiment of the present invention, the cross section of pillar 3 is rectangle.Rotary disk 6 is welded on the M place on pillar 3, and pillar 3 is through the center of rotary disk 6.

The L place, bottom of pillar 3 is welded with bearing block 8, M place and L place and carries out concentricity fine finishining.Bearing block is provided with rolling bearing 7, after having assembled, M place is by turning round roller and rotary disk forms single-revolution face, and L place forms another surface of revolution by rolling bearing, when external force applies, two surfaces of revolution just can realize the spinfunction of cantilever 1 and the relative fixed frame 4 of pillar 3.Because all rotations are all rolling friction, operation becomes very convenient.

Above specific embodiments of the invention are described.It is to be appreciated that the present invention is not limited to above-mentioned particular implementation, those skilled in the art can make various distortion or amendment within the scope of the claims, and this does not affect flesh and blood of the present invention.
