Abstract

The utility model provides a helical height adjustment device. A straight-line motor is hung between side beams of a frame, and the height adjustment device is directly arranged on the beams, and a screw rod is engaged by a special tool and supports an installation base; the helical lifting and the adjusting way of the pad are used to realize the precise and stepless height adjustment way, thereby maximally reducing the adjustment time for the running maintenance of the railbound vehicle. The helical height adjustment device is connected with the straight-line motor through a vertical suspension rod. The helical height adjustment device comprises a screw rod that is connected with the top end of the vertical suspension rod, and an installation base that is fixed on the beams, wherein, the screw rod passes through a through hole on the installation base and is projected outside the installation base. When the height is required to be adjusted, the special tool is used to be supported on the installation base and is engaged with the screw rod, the screw rod, the vertical suspension rod driven by the screw rod and the straight-line motor are lifted or lowered down by rotating the tool through the threading engagement, thereby adjusting the vertical distance between the straight-line motor and the rail induction plate.

Description

Spiral height adjuster

Technical field

The utility model relates to a kind of setting device of the vertical setting height(from bottom) of linear electric motors of guideway vehicle use, belongs to mechanical manufacturing field.

Background technology

The existing employed linear electric motors of rail vehicle truck, its vertical fixing and height adjustment generally is by being installed in wheel the support beam between the left and right journal box body to be realized.

When wheel is worn, takes turns the footpath when diminishing because of long-play, the vertical height of linear electric motors also can correspondingly change, and the spacing between linear electric motors and track tablet just need be regulated by height adjustment mechanism as if overshoot value scope.

Because the height adjustment mechanism of existing linear electric motors all is arranged on the journal box body, make the corresponding increase of single stage suspension quality, unfavorable of bogie truck to the guideway vehicle drive ability.Also cause simultaneously bogie truck overall space structure comparatively complicated, not only increased design difficulty, but also improved the manufacturing cost of bogie truck.

The utility model content

The utility model design goal is to provide a kind of spiral height adjuster, to address the above problem and design defect.Crossbeam between truck side sill is hung linear electric motors, height adjuster is set directly on the crossbeam, adopt special tool cooperation screw rod and support mount pad, the mode that spiral promotes, pad is adjusted, with realize accurately, height adjustment mode infinitely, reduce the required adjustment time of guideway vehicle operating maintenance to greatest extent.

Another design goal is, simplify bogie truck structure design, alleviate the framework quality, reduce manufacturing cost.

For achieving the above object, described spiral height adjuster is connected between linear electric motors and the crossbeam, and it connects linear electric motors by a vertical suspension rod.

Spiral height adjuster includes one and connects the screw rod on vertical suspension rod top, and is fixed on the mount pad on the crossbeam, and screw rod passes the through hole on mount pad top, and outstanding mount pad upper plane.

As above-mentioned scheme feature, when needing to adjust height, use special tool to be supported on the mount pad, and be meshed with screw rod, throw is by the engagement of screw thread, with screw rod, drive vertical suspension rod and promote or put down, thereby realize regulating vertical distance between linear electric motors and the track tablet together with linear electric motors by screw rod.

For improving the stability of spiral height adjuster, and improve vertical fastening performance of hanging linear electric motors, the further improvement project that can take is, the mount pad lower end is provided with a horizontal mounting surface, and attachment face is connected and fixed by bolt and hanging beam.

On the top of vertical suspension rod one mandrel is set, mandrel is connected and fixed by binding bolt and attachment face.

In addition, liner has one or more layers pad between the attachment face of mandrel and mount pad.

As mentioned above, the spiral height adjuster of the utility model has the following advantages and beneficial effect:

1, adopt screw rod to pass mount pad, special tool is by supporting the mode of mount pad and engagement screws, the vertical height of the linear electric motors of hanging is easy to regulate, this regulative mode comparatively accurately and need not to change or dismantle other truck components, the therefore operating maintenance time that can save bogie truck to greatest extent.

2, adopt this type of height adjuster, can simplify bogie structure effectively, alleviate the framework quality to reduce manufacturing cost.

Description of drawings

In conjunction with following accompanying drawing the utility model is further specified.

Fig. 1 is that schematic linear electric motors are hung shaft side figure;

Fig. 2 is the scheme drawing of spiral height adjuster;

Fig. 3 is the partial cutaway schematic of Fig. 2.

As shown in Figure 1 to Figure 3, linear electric motors 1, vertical suspension rod 2, crossbeam 3, binding bolt 4, screw rod 5, mount pad 6, attachment face 61, mandrel 7.

The specific embodiment

Embodiment 1, and as shown in Figure 1 to Figure 3, described spiral height adjuster is applied to linear electric motors 1 height adjustment of rail vehicle truck.Wherein, linear electric motors are hung on two crossbeams 3 of same bogie truck by 3 vertical suspension rods 2.

Spiral height adjuster includes one and connects the screw rod 5 on vertical suspension rod 2 tops and be fixed on mount pad (6) on the crossbeam 3.

Screw rod 5 passes mount pad 6 top through holes, and protrudes in mount pad.

Mount pad 6 has a horizontal mounting surface 61, and attachment face 61 is connected and fixed by bolt and crossbeam 3.

One mandrel 7 is set on the top of vertical suspension rod 2, and mandrel 7 is connected and fixed by binding bolt 4 and attachment face 61, and liner has one deck pad between mandrel 7 and attachment face 61.

When carrying out height adjustment, unclamp the binding bolt 4 of vertical suspension rod 2 and truck transom 3 coupling ends, realize that by special tool screw rod 5 ground screw, the lower surface of special tool is pressed on the upper surface of mount pad 6 simultaneously.

Little by little vertical suspension rod 2 is mentioned together with linear electric motors 1 by rotation.

When between the attachment face 61 of the mandrel 7 of vertical suspension rod 2 and mount pad 6 enough gaps being arranged, ready pad is put into.

Then, rotate special tool in the opposite direction, make vertical suspension rod 2 fall, tighten binding bolt 4 to finish height adjustment.
