Abstract

A kind of proximity sensor mounting bracket, it is characterised in that：Including installing plate, two side plates, two cant boards, box upper and lower plates, gusset and bottom plate, installing plate and two side plates and box upper and lower plates and left side vertical plate form box-structure, right side riser is welded with interior plate, gusset is welded between the cant board of left and right, connecting bottom board below two cant boards, entire stent is welded, main body is box-structure, lightening hole is had on four blocks of installing plate of box-structure, outer panel and box upper and lower plates plates, osculum is provided in box lower plate minimum point, bottom plate is machined with mounting hole.While the major advantage of the utility model is to mitigate weight, the mode and intensity of stent are improved；Weight is reduced to 21KG by 80KG, and weight reduces 51KG；Mode increases to 120HZ by former 60HZ, adds 60HZ；Improve safe clearance.

Description

A kind of proximity sensor mounting bracket

Technical field

The utility model belongs to city railway vehicle technical field, more particularly, to a kind of novel proximity sensor mounting bracket.

Background technology

Proximity sensor mounting bracket major function is carrying signal equipment；The brain that signalling arrangement is run as vehicle, Car speed is controlled, is a very crucial component；To ensure that signalling arrangement can work normally, mounting bracket needs have Enough intensity and mode；The more and more part strengths of railcar are met the requirements, but are also present in actual moving process The situation of damage, and the most of parts damaged are all as caused by vibration, mode reflects the dynamic-form of part, is designing Increasingly pay attention in the process；Weight is also key factor for bogie simultaneously；

Existing structure can only be using 4 mounting holes 1 on motor hanger on framework, such as Fig. 1；And in signal installation requirement signal The heart is overlapped with bogie longitudinal centre line；Therefore, the design to stent adds difficulty.

Existing stent 2 is complicated, and signalling arrangement 3 is mounted on stent in the following, such as Fig. 2, for workshop actual welding and machine Add and create great difficulties；Weight 80kg is heavier, Strength Safety surplus deficiency, causes potential danger to later stage operation and maintenance, increases Buying and manufacture cost.

Utility model content

The purpose of this utility model is to provide one kind and is simple to manufacture, light-weight, Strength Safety surplus abundance, buying and manufacture Proximity sensor mounting bracket at low cost.

To achieve the above object, the utility model provides a kind of proximity sensor mounting bracket, it is characterised in that：Including peace Loading board, two side plates, two cant boards, box upper and lower plates, gusset and bottom plate, installing plate and two side plates and box upper and lower plates Box-structure is formed with left side vertical plate, right side riser is welded with interior plate, gusset, two sides is welded between the cant board of left and right Connecting bottom board below riser, entire stent are welded, and main body is box-structure, the installing plate of box-structure, outer panel and Lightening hole is had on four blocks of plates of box upper and lower plates, is provided with osculum in box lower plate minimum point, bottom plate is machined with mounting hole.

For by the stress transfer of commissure to base material, the close junction and right side riser with installing plate of side plate with it is interior The junction of side plate uses rounded structure.

While the major advantage of the utility model is to mitigate weight, the mode and intensity of stent are improved；Weight by 80KG is reduced to 21KG, and weight reduces 51KG；Mode increases to 120HZ by former 60HZ, adds 60HZ；It improves more than safety Amount.

Specific embodiment

With reference to Fig. 3, the utility model stent 5 is welded using steel plate, and main body uses box-structure, passes through installation bolt 4 are mounted on motor hanger, and proximity sensor 6 is mounted below stent 5.

With reference to Fig. 4, Fig. 5, Fig. 6 a, 6b, the utility model includes installing plate 7, outer panel 8, interior plate 12, left side vertical plate 11st, right side riser 13, box upper plate 9, box lower plate 18, gusset 15 and bottom plate 14, on installing plate and two side plates and box Lower plate and left side vertical plate form box-structure, are welded with right side riser 13 with interior plate 12, muscle is welded between the cant board of left and right Plate 15, connecting bottom board 14 below two cant boards, in 9,18 4 pieces of the installing plate 7 of box-structure, outer panel 8 and box upper and lower plates Lightening hole 21,19,10,16 is had on plate, mitigates weight, while box internal water accumulation in order to prevent, it is minimum in box lower plate Point is provided with osculum 17, and bottom plate is installed to by four bolts on framework.

Because base material allowable stress is more than weld seam allowable stress, so maximum weighted position appears in position while welding danger close； For by the stress transfer of commissure to base material, side plate is close with the junction of installing plate and the company of right side riser and interior plate Place is met using rounded structure 20.

Claims

1. a kind of proximity sensor mounting bracket, it is characterised in that：Including in installing plate, two side plates, two cant boards, box Lower plate, gusset and bottom plate, installing plate and two side plates and box upper and lower plates and left side vertical plate form box-structure, with interior plate Be welded with right side riser, be welded with gusset between the cant board of left and right, connecting bottom board below two cant boards, entire stent welding and Into main body is box-structure, and loss of weight is had on four blocks of installing plate of box-structure, outer panel and box upper and lower plates plates Hole is provided with osculum in box lower plate minimum point, and bottom plate is machined with mounting hole.
