Abstract
The utility model relates to a device for removing heavy rail flaw detection residual water, which is formed by an air intake pipe, an air collecting pipe, nozzles and a bearing plate, wherein the air collecting pipe is a transverse U-shaped pipe, the air intake and the bearing plate are connected on the outer side of the U-shaped air collecting pipe, and at least six nozzles with different angels are arranged on the inner side of the air collecting pipe. As compressed air is used as the blowing power, the device has sufficiency resource, and does not add more devices, and has simple structure, less investment and self manufacturing. The nozzles have appropriate number and reasonable angle designs, which can be used to complete remove residual water on the head of a rail, the waist of the rail and the bottom of the rail, and guarantees a heavy rail not to scratch with a blowing device. Compared with the steam roasting, the device saves a great amount of steam, increases the inspection quality, eliminates safety hidden dangers, meets the manufacturing requirements of heavy rails in 100m length, and solves the bottleneck problems which restrict the manufacturing of the heavy rails in northern winters.
Description
Technical field
The utility model belongs to steel rolling auxiliary device field, is specifically related to a kind of pressurized air that utilizes and purge removes after the flaw detection device attached to the residual chilled water on heavy rail surface.
Background technology
Along with the speed-raising of train, increasing to the demand of high speed rail, the quality requirements for the high speed rail also improves constantly simultaneously.According to the producting rule regulation, the heavy rail that produce winter must be removed totally attached to the residual chilled water on heavy rail rail head, the web of the rail and flange of rail surface after flaw detection, freezes with the heavy rail surface that prevents postpartum, influences the heavy rail inherent quality.Yet,, therefore can't satisfy the production needs of 100m heavy rail owing to do not remove the device of heavy rail flaw detection rear surface residuary water in the former design technology flow process concerning growing tall the manufacturer of north cold area of fast rail through producing 100m after transforming.For addressing this problem, have to take in the processing line subsequent process, to use steam that rail is carried out heated baking, to eliminate remained on surface water.The defective of this method: the one, the baking velocity of evaporation is too slow, can't adapt to Heavy-rail Production speed and directly has influence on heavy rail output; The 2nd, need in the bake process to consume a large amount of steam, waste energy and strengthened cost; The 3rd, needing increases vapor baking equipment, has increased the occupation of capital; The 4th, residual chilled water had both influenced the quality of defect detecting test, again the supervisory personnel was formed certain potential safety hazard.
Summary of the invention
The purpose of this utility model is exactly at the problems referred to above, aims to provide a kind of pressurized air that utilizes operating heavy rail surface each several part is carried out the high pressure purging, to remove the device of heavy rail surface inspection residuary water.
The technical solution that the utility model is taked is:
A kind of removal heavy rail flaw detection residuary water device is made up of blast pipe, duct set, tuyere and backing plate.Duct set is horizontal " U " type pipe, is connected to blast pipe and backing plate in " U " type duct set outside, and 6 tuyeres that have different angles are set on the duct set inwall at least.
The tuyere quantity of recommending is 15.Its installation site is respectively: be provided with 4 at horizontal " U " type duct set vertical tube inwall, upper lateral tube is provided with 6, and lower transverse tubule is provided with 5.
The apparent wind mouth is far and near different apart from heavy rail, and tuyere is provided with long tuyere and two kinds of short tuyeres.Be the effect that guarantees to purge, the tuyere that is in diverse location on the different horizontal, vertical duct sets also adopts different setting angles, the i.e. position that purges according to this tuyere, determine the direction and the angle of its inclination, its angular range is: the angle between the duct set axis of tuyere axis and its installation site is 50 °～120 °.
The beneficial effects of the utility model are:
Because the utility model adopts pressurized air as purging power, the wide material sources abundance need not the more equipment of increase, and is simple in structure, but reduced investment and self manufacture.Duct set bore and blast, air quantity determine that according to purging factors such as needs and heavy rail travelling speed its matching degree can realize purging effect fully.It is suitable that tuyere quantity is selected, and angle design is reasonable, makes the residuary water of rail head, the web of the rail and flange of rail various piece can both online thorough removal, and not swipe blow device when guaranteeing that heavy rail orbits.Compare with vapor baking, saved a large amount of steam, improved and checked on the quality, eliminated potential safety hazard, satisfied the production needs of 100m heavy rail, solved the bottleneck problem of north of china in winter restriction Heavy-rail Production.
Description of drawings
Accompanying drawing is for removing heavy rail flaw detection residuary water apparatus structure synoptic diagram.
Among the figure: 1 is blast pipe, and 2 is duct set, and 3 are long tuyere, and 4 are short tuyere, and 5 is backing plate, and 6 is rail.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
By accompanying drawing as seen, the utility model is made up of blast pipe 1, duct set 2, long tuyere 3, short tuyere 4 and backing plate 5.
The global shape of duct set 2 is " U " type pipe that fell horizontal, can adopt ￠ 42mm steel tube bending to form.Vertically be connected to blast pipe 1 in the tube wall outside of section at " U " type duct set 2, blast pipe 1 links together with the external compression air pipe line.Be provided with one in the outside of " U " type duct set 2 lower transverse tubules backing plate 5 is installed, backing plate 5 is provided with screw hole, is connected on the base by bolt.
6 tuyeres that have different angles are set on duct set 2 inwalls at least, and are divided into long tuyere 3 and 4 two kinds of short tuyeres.The tuyere quantity that embodiment selects is 15; Be provided with 4 at horizontal " U " type duct set 2 vertical tube inwalls, upper lateral tube is provided with 6, and lower transverse tubule is provided with 5.For guaranteeing to purge effect, 4 long tuyeres 3 of use that the vertical tube inwall is provided with; 5 tuyeres of 6 of upper lateral tubes and lower transverse tubule are selected short tuyere 4 for use.
The tuyere system that is in diverse location on the different horizontal, vertical duct sets adopts different setting angles, determines the direction and the angle of its inclination according to the position of this tuyere purging.Be located at two middle install vertical of long tuyere 3 of duct set 2 vertical tube inwalls with riser axis; Two long tuyeres 3 of both sides slope inwardly respectively, with the exterior angle of riser axis be 100 °, promptly slope inwardly 80 °.Equally, 6 short tuyeres 4 on the upper lateral tube and 5 short tuyeres 4 on the lower transverse tubule, the also position that is purged according to residing position correspondence separately, adopt respectively with its duct set axis normal or to the mounting means of purging position inclination, its angle is calculated by the angle less than 90 °, is advisable in 60 °～75 ° scope in general inclination angle.
