Abstract
The invention relates to the technical field of electrical hoists and in particular relates to an elasticity adjusting device for a rope guider of an electrical hoist. The elasticity adjusting device comprises a plurality of rope guide blocks and a plurality of springs, wherein an upper limiting plate and a lower limiting plate are fixedly arranged on one rope guide block and integrated with the rope guide block; grooves are symmetrically formed in the two ends of each rope guide block, and buffer cushions are fixedly connected to the two end surfaces of the rope guide block; through holes are formed in the buffer cushions; the middle section of each spring is embedded into each through hole, the two ends of the spring are arranged in the grooves, connecting blocks are fixedly connected to the two ends of the spring and have T-shaped cross sections, and one end of each connecting block is fixed to the bottom surface of each groove through a screw. When the elasticity adjusting device is used, the springs can guarantee the circular shape of the rope guider in a tightening process, so that the problem of groove jumping of a steel wire rope due to wear of the rope guide blocks is solved. The elasticity adjusting device has the advantages of simple structure, reasonable arrangement, low manufacturing cost and the like.
Description
Technical field
The present invention relates to electric block technical field, particularly the slack adjuster of electric hoist conductor rope device.
Background technology
The features such as electric block is a kind of extraordinary weight-lifting equipment, and be installed on overhead traveling crane, gauntry crane, it is little that electric block has volume, from heavy and light, simple to operate, easy to use, for industrial and mining enterprises, the places such as storage harbour.
Existing electric hoist conductor rope device just there will be wearing and tearing after Long-Time Service, and job-hopping just appears in steel rope, and rope guide was lost efficacy.In order to address this problem, in industry, do a large amount of significant exploration work.Such as now the patent No. is 200920140423.8, and name is called: electric hoist conductor rope device, and it adopts the coupling mechanism of a band spring automatically to regulate the tensioning of rope guide.As everyone knows, the rounded shape of rope guide, is surrounded mutually by multiple conductor rope block; And the coupling mechanism with spring is only connected to wherein two conductor rope blocks, so when only having two conductor rope blocks to occur wearing and tearing, the coupling mechanism of spring just can solve the problem bringing groove skipping of steel rope while because of the wearing and tearing of conductor rope block; When there are wearing and tearing for other conductor rope block, the fastening function of the coupling mechanism of spring only can make rope guide be out of shape, and it is not regular toroidal that rope guide is become, and so, steel rope still there will be job-hopping.Therefore necessity is improved rope guide structure.
Summary of the invention
The object of the invention is to the defect for prior art and deficiency, provide a kind of structure simple, the slack adjuster of electric hoist conductor rope device reasonable in design, easy to use.
For achieving the above object, the technical solution used in the present invention is:
The slack adjuster of electric hoist conductor rope device of the present invention, includes several conductor rope blocks, and one of them conductor rope block is fixedly installed upper limit plate and lower limiting board, and upper limit plate and lower limiting board are made of one piece with this conductor rope block; The two ends of described conductor rope block are all symmetrically arranged with slot, and the both ends of the surface of described conductor rope block are also fixedly connected with cushion rubber; Described cushion rubber is provided with through hole, it also includes some springs, the interlude of spring is embedded in through-holes, the two ends of spring are all arranged in slot, the two ends of spring are all fixedly connected with contiguous block, the cross section shape in T shape of contiguous block, contiguous block one end is all screwed on the bottom surface of slot.
Further, top, described slot is closely embedded with pressing plate, and pressing plate is positioned at directly over screw and spring.
Further, described cushion rubber adopts EVA material to be made.
Further, the diameter of described through hole is greater than the diameter of spring.
After adopting said structure, beneficial effect of the present invention is: the slack adjuster of electric hoist conductor rope device of the present invention, include several conductor rope blocks, one of them conductor rope block is fixedly installed upper limit plate and lower limiting board, and upper limit plate and lower limiting board are made of one piece with this conductor rope block; The two ends of described conductor rope block are all symmetrically arranged with slot, and the both ends of the surface of described conductor rope block are also fixedly connected with cushion rubber; Described cushion rubber is provided with through hole, it also includes some springs, the interlude of spring is embedded in through-holes, the two ends of spring are all arranged in slot, the two ends of spring are all fixedly connected with contiguous block, the cross section shape in T shape of contiguous block, contiguous block one end is all screwed on the bottom surface of slot.When using of the present invention, each conductor rope block is all connected by spring, the both ends of the surface of each conductor rope block are connected with cushion rubber, make spring can ensure the toroidal of rope guide in tightening process, so just, the problem bringing groove skipping of steel rope while because of the wearing and tearing of conductor rope block can be solved, greatly effectively extend the service life of rope guide.It is simple that the present invention has structure, arranges rationally, the advantages such as cost of manufacture is low.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further illustrated.
As shown in Figure 1-2, the slack adjuster of electric hoist conductor rope device of the present invention, include several conductor rope blocks 1, one of them conductor rope block 1 is fixedly installed upper limit plate 3 and lower limiting board 4, and upper limit plate 3 and lower limiting board 4 are made of one piece with this conductor rope block 1; The two ends of described conductor rope block 1 are all symmetrically arranged with slot 1-1, and the both ends of the surface of described conductor rope block 1 are also fixedly connected with cushion rubber 2, and this connection adopts glue to fix; Described cushion rubber 2 is provided with through hole 2-1, it also includes some springs 6, the interlude of spring 6 is embedded in through hole 2-1, the two ends of spring 6 are all arranged in the 1-1 of slot, the two ends of spring 6 are all fixedly connected with contiguous block 7, the cross section shape in T shape of contiguous block 7, contiguous block 7 one end is all fixed on by screw 5 on the bottom surface of slot 1-1, and every two conductor rope blocks 1 are all fixedly connected by spring 6.
Further, 1-1 top, described slot is closely embedded with pressing plate 8, and pressing plate 8 is positioned at directly over screw 5 and spring 6, mainly plays the effect of hiding shame.
Further, described cushion rubber 2 adopts EVA material to be made.
Further, the diameter of described through hole 2-1 is greater than the diameter of spring 6, and when spring 6 drives conductor rope block 1 to move in opposite directions, cushion rubber 2 can not produce with spring 6 because of distortion and rub, and what ensure spring 6 further tightens up effect.
When using of the present invention, each conductor rope block is all connected by spring, the both ends of the surface of each conductor rope block are connected with cushion rubber, make spring can ensure the toroidal of rope guide in tightening process, so just, the problem bringing groove skipping of steel rope while because of the wearing and tearing of conductor rope block can be solved, greatly effectively extend the service life of rope guide.In addition, this structure is simple, reasonable in design, low cost of manufacture.
The above is only better embodiment of the present invention, therefore all equivalences done according to structure, feature and the principle described in patent claim of the present invention change or modify, and are included in patent claim of the present invention.
