Abstract
The utility model discloses a kind of for the chain hoist wheel in tightener, belong to tightener part technical field.It is formed by connecting by bearing support and these two weldments of discoid disc, and discoid disc or a hot extrusion part, its drop center portion with grooving that there is disc main body portion, extend to form along the circumferencial direction of disc main body portion.After adopting technique scheme, the utility model is cheap for manufacturing cost, light self-weight is expected to be reduced, and naturally would not occur the generation of suspension hook flop phenomenon, can play the effect effectively preventing suspension hook heel and toe wear and suspension hook corrupted thus when forming two movable pulley ﹣ hook type with suspension hook.
Description
[technical field]
The utility model relates to a kind of for the chain hoist wheel in tightener, belongs to the part technical field in tightener.
[background technique]
Tightener is a kind of easy to operate tension device, is widely used in the infrastructural projects such as national grid, used as tension wire in overhead line cable laying operation.Chain hoist wheel in tightener is then the indispensable cast iron part of tightener, for guiding steel wire rope.Common chain hoist wheel comprises for bearings mounted bearing support, disc, wheel rim with grooving, and wherein, its longitudinal section of grooving is U-shaped, and along disc two surface, radially radial separation is distributed with multiple rib.
Carefully analyze said structure, be not difficult to find that this existing chain hoist wheel exists following deficiency: because chain hoist wheel is with pig iron HT200 (carbon content is high) for raw material, formed by mold integral casting, mould is die sinking high expensive greatly thus.Diameter be 335mm chain hoist wheel its be 7.1Kg from weight, there is the deficiency that weight is bigger than normal, when this chain hoist wheel is assembled on tightener with two movable pulley ﹣ hook type, because these two movable pulley speed differ, position is large from weight at upper pulley, and position suspension hook light self-weight down, during tightener no-load running, suspension hook easily overturns and causes heel and toe wear, and it is serious that suspension hook damages phenomenon.
[model utility content]
Technical problem to be solved in the utility model is the deficiency that exists for above-mentioned prior art and provides a kind of for the chain hoist wheel in tightener, this chain hoist wheel is cheap for manufacturing cost, light self-weight, and forms two movable pulley-hook type with suspension hook and overturn for making suspension hook during tightener no-load running.
It is as follows that the utility model solves the problems of the technologies described above adopted technological scheme:
A kind of for the chain hoist wheel in tightener, it is formed by connecting by bearing support and these two weldments of discoid disc, and discoid disc or a hot extrusion part, its drop center portion with grooving that there is disc main body portion, extend to form along the circumferencial direction of disc main body portion.
Above-mentioned drop center portion has flanging.
Above-mentioned bearing support have shoulder every and jump-ring slot.
The utility model compared with prior art tool has the following advantages and beneficial effect:
The utility model is connected to form by bearing support and these two split parts of discoid disc, discoid disc as hot extrusion part has disc main body portion, drop center portion and grooving, meet basic structure and the function of chain hoist wheel, cheap for manufacturing cost, light self-weight, when forming two movable pulley ﹣ hook type with suspension hook, would not there is the generation of suspension hook flop phenomenon in nature during tightener no-load running, therefore can play the effect effectively preventing suspension hook heel and toe wear and suspension hook corrupted.
The grooving with flanging can prevent wire rope sharp edge.
[accompanying drawing explanation]
Be described in further detail with regard to the utility model below in conjunction with accompanying drawing.
Fig. 1 is structural representation of the present utility model.
[embodiment]
Refer to shown in Fig. 1, a kind of for the chain hoist wheel in tightener, it is formed by connecting by bearing support 1 and these two weldments of discoid disc 2, and discoid disc 2 or a hot extrusion part, its drop center portion 22 with grooving 220 that there is disc main body portion 21, extend to form along the circumferencial direction of disc main body portion 21.
Bearing support 1 adopts existing pipe on the market to cut through the laggard driving of cutting and processes, bearing support 1 selection wide material sources; Discoid disc 2 adopts solid wrought iron Q235B General Structural Steel to be raw material, after centering, hot-extrusion mold carries out operation, to process the drop center portion 22 with grooving 220.
Drop center portion 22 has flanging 221, and from figure, discoid its longitudinal section of disc 2 is Y-shaped.
Bearing support 1 has shoulder every 11 and jump-ring slot 10, after bearing support 1 inserts bearing (not shown), takes on and locates for bearing every 11 and jump-ring slot 10.
Because bearing support material is existing, therefore in the whole chain hoist wheel manufacture process of the utility model, only need the processing mold of discoid disc 2, mould is little, and die sinking cost savings are many, the low cost of manufacture of whole chain hoist wheel.
The utility model chain hoist wheel is applied in tightener, can be used as static pulley, movable pulley uses.
Claims (3)
1. one kind for the chain hoist wheel in tightener, it is characterized in that: it is formed by connecting by bearing support and these two weldments of discoid disc, and discoid disc or a hot extrusion part, its drop center portion with grooving that there is disc main body portion, extend to form along the circumferencial direction of disc main body portion.
2. chain hoist wheel according to claim 1, is characterized in that: described drop center portion has flanging.
