Abstract

The utility model relates to a device for cleaning the end of a brake beam of a truck, which comprises a brush and a driving device which drives the brush to make reciprocating sliding on the plane. The brush is driven by the driving device to make reciprocating straight-line movement, the surface of a rectangular head can be automatically cleaned or descaled, so that the problems that the manualoperation is difficult and the labor intensity is large can be solved.

Description

Be used to clear up the device of van brake beam termination

Technical field

The utility model relates to a kind of device that is used to clear up the van brake beam termination.

Background technology

The railway freight-car brake beam is to be used for brake force mean allocation that brake lever is transmitted, again power is put on member on the wheel tread by brake shoe.As seen, brake beam is the important Force transmission parts of freight car braking, and its damage or fracture can make brake fade when light, cause the lorry disturbing accident when serious easily.Existing van brake beam adopts L-B mostly, the L-C type, its beam is as arc, two terminations become short rectangle head by the short cylindrical shape head, be commonly called as and be " homalocephalus brake beam ", and the periphery at the rectangle head also is equipped with the overcoat that is made of nylon material, and with rivet rectangle head and overcoat is fixed together.Because the rectangle head at square brake beam two ends is the reversed of stress stress points that imbed in the bogie hold-down support, be that fatigue crack is concentrated the keypoint part that takes place, so, other position of the relative brake beam of rectangle head is the position of easy damage and crack, and this position damage can threaten the railway freight-car traffic safety equally.

For this reason, to brake beam, particularly the two ends Inspection and Repair of Brake Beams has the regulation of detailed strictness in the relevant regulation of inspection and repair of railway interests, wears away the limit crackle as nylon jacket, more renew cover; Surface derusting and defect detecting test to be carried out to the rectangle head, and to before the defect detecting test of rectangle head, just nondestructive inspection can be carried out after at first will thoroughly removing the surface corrosion thing.Prior art unique way that rust cleaning is adopted to the rectangle head of brake beam two ends is manually with the steel brush rectangle head surface that directly rubs, to remove its surface corrosion thing.Though this kind rust cleaning mode cost is lower, but because the rectangle head is installed on the repairing frame, its operating space is very little, and the upper and lower surfaces operator of rectangle head can't see, when these two faces of friction, brake beam upset need be made the operator can be visual to the rust cleaning that could rub of rectangle head, so, eliminate rust manually that not only labour intensity is big, and operation is extremely inconvenient, its efficient is also very low, and the rust cleaning effect is also undesirable.

The name of No. 2780408 bulletins of Chinese patent is called a kind of equipment that just is used for the brake beam rust cleaning that " a kind of Railway Freight Car Repair brake beam ballasting rust remover " provides, and this equipment is to clear up brake beam by the mode of ball blast.But, because the space of brake beam rectangle head position is less, and could clear up it after only making rivet and overcoat withdraw from the rectangle head, so the equipment that this patent proposed is not suitable for clearing up the rectangle head section of brake beam.Up to the present, also there is not to find to be specifically designed to the special equipment of the rectangle head section of clearing up brake beam.

Summary of the invention

The purpose of this utility model provides a kind of mode of utilizing brusher to wipe the rectangle head surface is eliminated rust to solve the device that is used to clear up the van brake beam termination of problems such as inconvenient operation and labour intensity are big.

The drive unit that the device that the utility model proposed is used to clear up the van brake beam termination comprises brush and this brush can be slided in the flatness and reciprocator at place.

Described drive unit comprises casing, in this casing is provided with through hole that the brush holder that allows brush inserts and is installed in casing and the guide housing that is connected with brush holder, and be installed in the guide housing and sliding shoe moving up and down, and in sliding shoe, be provided with the eccentric wheel that has eccentric shaft, outside casing, also be provided with the power set that are used to drive the eccentric shaft rotation, and be connected by flexible axle between the output that makes power set and the eccentric shaft.

Be provided with two up and down between described brush with being separated with certain distance, and the both sides of extending casing respectively, the brush holder two ends of each brush.

Described drive unit is made of linear electric motors.

The utility model proposed is used for clearing up rotatablely moving that the eccentric wheel of the device of van brake beam termination can provide drive unit and changes over the straight reciprocating motion of guide housing, thereby brush can be moved reciprocatingly along the plane at rectangle head place, the rectangle head surface is cleared up automatically or is eliminated rust, not only can solve problems such as manually-operated difficulty and labour intensity are big, and can improve operating efficiency widely; Drive unit adopts the structure that flexible axle is connected with power set simultaneously, and flexible axle can be arbitrarily crooked, makes this device lightly nimble, is suitable for operation under multiple rugged environments such as crawl space.

Description of drawings

Accompanying drawing 1 provides that the utility model proposes is used for clearing up the outward appearance cross-sectional view of the device drive unit and an embodiment of brush of van brake beam termination.

The specific embodiment

Referring to Fig. 1, this figure provides that the utility model proposes is used to clear up the outward appearance cross-sectional view of an embodiment of device of van brake beam termination.This device comprises brush 1 and drive unit 2, and wherein, the bristle 11 of brush 1 can adopt steel wire to constitute, and brush holder 12 adopts the plate of a prolongation.Brush 1 is provided with two up and down, and makes bristle 11 relative.

Drive unit 2 comprises casing 21, the through hole 22 that the brush holder 12 that allows brush 1 inserts is installed in this casing 21 and is installed in guide housing 23 on the brush holder 12, and this guide housing 23 is to be made of the vertical plate that two interblocks are separated with certain distance.The sliding shoe moving up and down 24 that external diameter and its internal diameter are complementary is installed in guide housing 23, and from appearance, sliding shoe 24 is rectangular blocks, and the zone is provided with an eccentric wheel 25 that has eccentric shaft 26 in the middle.When eccentric shaft 26 drives eccentric wheel 25 rotations, sliding shoe 24 is moved along two-dimensional directional, and when sliding shoe 24 is transversely mobile, can force guide housing 23 to move along horizontal direction, also move thereby drive brush 1, brush 1 is placed on the surface of brake beam rectangle head 4, bristle 11 and its mantle friction along horizontal direction, can clear up its surface, to realize rust cleaning.Drive unit 2 is provided with two up and down, and direction is opposite, and about in the of 4 two surfaces to realize clearing up brake beam rectangle head simultaneously.The power set that drive eccentric shaft 26 can adopt motor or hydraulic test or other that equipment of rotary power can be provided, because of these power set belong to prior art, so, do not provide concrete structure among the figure.Can be connected by flexible axle 27 between eccentric shaft 26 and the power set,, can make drive unit 2 extend into any position in the van brake beam because of flexible axle 27 can be arbitrarily crooked.

Because of drive unit 2 is the parts that straight reciprocating motion is provided for brush 1, and linear electric motors are parts of straight reciprocating motion, so drive unit 2 can be made of linear electric motors.
