Description

Special lifting appliance with brake disc wheels

Technical Field

The invention relates to the technical field of wheel hoisting of railway vehicles, in particular to a special hoisting tool with a brake disc wheel.

Background

As shown in fig. 1 and 2, in the production of the wheel set of the railway vehicle, since the brake disc 8 needs to be mounted on the wheel 7, if the brake disc 8 is mounted on the single wheel 7, the gap between the rim edge of the wheel and the outer edge of the brake disc will become narrow, and meanwhile, the noise reduction ring 9 is mounted to further compress the space with the narrow gap, so that the existing wheel sling has no mounting space and cannot be used. For this reason, the existing wheel set production process flow is: single wheel machining-single wheel painting-inboard brake disc hanging on axle-wheel press-on-wheel brake disc and noise reduction ring mounting. The process avoids the problem that a single wheel provided with a brake disc cannot be lifted, but has the following defects: the wheel pair can only be lifted through the mode of hanging the axle spindle through the hanging belt after the wheel pair is pressed and assembled, time and labor are wasted, meanwhile, as the brake disc 8 needs to be firstly hung on the axle body of the axle 10 before being installed, the brake disc 8 or the axle 10 is easy to collide and hurt when the wheel 7 is pressed and assembled, the product quality is influenced, the manufacturing cost is increased, and the installation efficiency is reduced.

Disclosure of Invention

The invention provides a special lifting appliance with a brake disc wheel, aiming at solving the technical problems that the prior lifting appliance cannot be used for lifting the wheel due to narrow space caused by pre-mounting the brake disc on the wheel and the brake disc or the axle is easy to be knocked due to pre-hanging the brake disc on the axle.

The technical scheme adopted for solving the technical problems is as follows:

the special lifting appliance is characterized by comprising an outer lifting plate, an inner lifting plate, a wheel center lifting ring, a whole axle wheel set lifting ring, cylindrical pins and supporting bars, wherein the outer lifting plate consists of an L-shaped plate and an outer arc-shaped inserting plate fixedly connected to the bottom of the vertical section of the L-shaped plate, and the radian of the outer arc-shaped inserting plate is the same as that of a wheel rim; the support bar is fixed at the inner side of the outer arc plugboard along with the shape; the inner side hanging plate consists of a 1-shaped plate and an inner side arc-shaped inserting plate fixedly connected to the bottom of the 1-shaped plate, and the radian of the inner side arc-shaped inserting plate is the same as that of the wheel rim; the wheel center of mass hanging ring shaft is connected to the middle position of the L-shaped plate horizontal section, the whole axle wheel pair hanging ring shaft is connected to the connection position of the top of the 1-shaped plate and the end of the L-shaped plate horizontal section, and the cylindrical pin is inserted into the connection position to lock the outer hanging plate and the inner hanging plate.

The beneficial effects of the invention are as follows: the single wheel can be lifted by using one lifting appliance, and the whole wheel set can be lifted by using two lifting appliances. The operation is flexible, the clamping is convenient, and the production efficiency is improved; the arc-shaped plugboards can be used for positioning and lifting under the condition of a narrow space after the wheels are provided with the brake discs, so that the lifting of single wheels and wheel pairs can be satisfied; the brake disc cannot be damaged in the lifting process, and the stability and the safety are good.

The lifting appliance can adjust the technological process of wheel set production, realizes reasonable technological process, improves working efficiency, and can successfully avoid the noise reduction ring and prevent damage to the noise reduction ring due to the fact that the noise reduction ring is required to be installed before the brake disc is installed.

Detailed Description

The invention is described in further detail below with reference to the accompanying drawings.

As shown in fig. 3 to 7, the special sling for a wheel with a brake disc of the present invention comprises: the wheel rim comprises an outer side hanging plate 1, an inner side hanging plate 2, a wheel center of mass hanging ring 3, a whole axle wheel pair hanging ring 4, cylindrical pins 5 and supporting bars 6, wherein the outer side hanging plate 1 is composed of an L-shaped plate 1-1 and an outer side arc inserting plate 1-2 fixedly connected to the bottom of the vertical section of the L-shaped plate 1-1, and the radian of the outer side arc inserting plate 1-2 is the same as that of the wheel rim; the support bar 6 is fixed at the inner side of the outer arc plugboard 1-2 along with the shape; the inner side hanger plate 2 is composed of a 1-shaped plate 2-1 and an inner side arc insertion plate 2-2 fixedly connected to the bottom of the 1-shaped plate 2-1, and the radian of the inner side arc insertion plate 2-2 is the same as that of a wheel rim; the wheel center of mass rings 3 are connected to the middle position of the horizontal section of the L-shaped plate 1-1 in an axial mode, the whole axle wheel set rings 4 are connected to the connecting position of the top of the 1-shaped plate 2-1 and the end of the horizontal section of the L-shaped plate 1-1 in an axial mode, when the wheel center of mass rings are used, an angle of 45 degrees is formed between the wheel center of mass rings and the horizontal plane, and cylindrical pins 5 are inserted into the connecting position to lock the outer side hanging plate 1 and the inner side hanging plate 2. The wheel center of mass lifting ring 3 is used when a single wheel 7 is lifted, the whole axle wheel set lifting ring 4 is used when the whole wheel set is lifted, the cylindrical pin 5 is used for preventing the outer arc inserting plate 1-2 and the inner arc inserting plate 2-2 from being separated from the wheel 7 in the lifting process, and the lifting safety is ensured. In the lifting process, the cylindrical pins 5 are inserted to lock the outer lifting plate 1 and the inner lifting plate 2, the inner crotch surfaces of the outer lifting plate 1 and the inner lifting plate 2 and the side surface of the rim of the wheel 7 form limit together, the left and right movement of the lifting appliance is limited, and the noise reduction ring 9 is prevented from being crushed.

As shown in fig. 6 and 7, when the special lifting appliance with the brake disc wheel is used, firstly, the cylindrical pin 5 is pulled out, the inner side lifting plate 2 is pulled out by taking the pin shaft of the lifting ring 4 of the whole axle pair as a rotating shaft, then the outer side lifting plate 1 and the inner side lifting plate 2 are correspondingly inserted into a gap between the brake disc 8 and the wheel 7, the support bar 6 is supported on the inner end surface of the rim of the wheel 7, and the two side faces of the rim are correspondingly contacted and limited with the inner crotch surfaces of the outer side lifting plate 1 and the inner side lifting plate 2; then the cylindrical pin 5 is inserted into the lifting appliance, and the outer side lifting plate 1 and the inner side lifting plate 2 are locked; when a single wheel 7 needs to be lifted, a steel wire rope is used for hooking the wheel center of mass lifting ring 3 to realize lifting; when the whole wheel pair is required to be lifted, two steel wire ropes are correspondingly hooked on the two whole-shaft wheel pair lifting rings 4 to realize lifting.
