Abstract

The utility model discloses clamping belt assembly for locomotive air cylinders. The clamping belt assembly comprises a clamping belt. A circular cylinder block fitted with an air cylinder is arranged, clamping belt holes and bolt mounting holes are formed in two ends of the cylinder block, the clamping belt penetrates the clamping belt holes in the two ends of the cylinder block to encircle the air cylinder, the clamping belt and the cylinder block are tightly fixed onto the air cylinder through a shaft pin fastening structure at the end portion of the clamping belt, and the air cylinder is mounted in place through a bolt structure and the bolt mounting holes in the cylinder block. The air cylinder is mounted reliably, conveniently and easily and attractively. The clamping belt assembly is applicable to all the air cylinders in locomotive air brake system pipelines; selection of the assembling space for the air cylinders is more flexible, especially for the surplus space on the wall space, and convenience in assembly is achieved; the clamping belt assembly is also applicable to larger air cylinders (such as main air cylinders), and the structure of the base part is strong enough to support and fix the air cylinders in the clamping belt assembly.

Description

The assembling of locomotive reservoir cassette tape

Technical field

The utility model relates to a kind of locomotive reservoir cassette tape assembling, belongs to railway locomotive technical field.

Background technology

In locomotive air brake line, reservoir is more, and larger is locomotive main air reservoir, and purposes is the pressure air producing for storing air compressor, the pressure container using to supply with locomotive brake gear and other auxiliary air supply systems.Take JZ-7 type Pneumatic brake systems as example, in air pipe system, have total reservoir, time for balance reservoir, the reservoirs such as urgent-application reservoir, step-down-work reservoir, low pressure reservoir and supplementary reservoir.In prior art, the many medium and small reservoir of locomotive (except the large reservoirs such as total reservoir) generally adopts two kinds of mount schemes.Scheme is cassette tape or card rod are realized a reservoir installation by fastener, and the mount pad of reservoir adopts the version of angle steel to be welded in vehicle body bottom frame cover plate or car body partition wall conventionally, has fastener connecting bore on mount pad.Specifically as depicted in figs. 1 and 2.This scheme need to be at vehicle body bottom frame cover plate or car body partition wall prewelding mounting seat of air cylinder, once position needs to adjust, capable of regulating amount is less.When adjustment amount is large, need to again weld mounting seat of air cylinder.Another kind of scheme is on reservoir cylinder body, directly to weld two symmetrical reservoir seats, on reservoir seat, has tapped bore, has fastener connecting bore on brake cabinet adapter plate, by four bolts, directly fixes reservoir.Specific constructive form is as Fig. 3, and the version of reservoir seat as shown in Figure 4.This scheme reservoir seat is directly welded on reservoir, can increase like this stress at welding air cylinder place, reduces reservoir intensity; In order to guarantee reservoir constant intensity, must guarantee the reservoir seat upper screwed hole degree of depth, the thickness of reservoir seat is thicker like this, so relatively not light simultaneously.

Utility model content

The purpose of this utility model overcomes the deficiency of above-mentioned prior art exactly, and a kind of locomotive reservoir cassette tape assembling is provided.

The purpose of this utility model is achieved in that a kind of locomotive reservoir cassette tape assembling, comprise cassette tape, it is characterized in that arranging a circular arc cylinder seat of fitting mutually with reservoir, the two ends of cylinder seat have cassette tape hole and hold-down bolt hole, cassette tape is through the cassette tape hole at cylinder seat two ends and around reservoir, the pivot pin fastener constructions of cassette tape end is fastened to cassette tape and cylinder seat on reservoir, by the hold-down bolt hole on bolt arrangement and cylinder seat, reservoir is in place.

Scheme of the present utility model, reservoir is installed reliable, convenient, attractive in appearance.To all reservoirs in locomotive air brake line, this scheme is all suitable for, and makes the installing space selection of reservoir more flexible, and especially for surplus space on metope, this form is convenient to install.This cassette tape assembling form is suitable for larger reservoir (as total reservoir) too, only need make the structure of base portion in cassette tape assembling have enough strength support to fix reservoir.

In figure, be labeled as: 1-angle steel, 2-bolt, 3-reservoir, 4-card rod, 5-cassette tape, 6-welded type reservoir seat, 7-monomer reservoir seat, 8-cassette tape hole, 9-bolt hole, 10-pivot pin fastening structure, 11-rubber pad.

The specific embodiment

For making object, technical scheme and the advantage of the utility model embodiment clearer, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.

Referring to Fig. 4～Fig. 6, the locomotive reservoir cassette tape assembling of the present embodiment, designs according to reservoir cylinder diameter the monomer reservoir base 7 that cassette tape assembles.On base, have 2 installations bolt hole 9 and two cassette tape holes 8. that cassette tape 5 is passed to two cassette tape holes 8, anti-fire-retardant rubber pad 11 is housed between cassette tape 5 and reservoir 3 increases resistance, and reservoir 3 is fastening by the pivot pin fastening structure 10 on cassette tape 5.A reservoir can, with two cassette tape assemblings, 4 bolts hole, fasten with 2 of loose-proof fastening bolts totally on installation site.

Finally it should be noted that: above embodiment only, in order to the technical solution of the utility model to be described, is not intended to limit; Although the utility model is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: its technical scheme that still can record aforementioned each embodiment is modified, or part technical characterictic is wherein equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution depart from the spirit and scope of the each embodiment technical scheme of the utility model.

Claims

1. a locomotive reservoir cassette tape assembling, comprise cassette tape, it is characterized in that arranging a circular arc cylinder seat of fitting mutually with reservoir, the two ends of cylinder seat have cassette tape hole and hold-down bolt hole, cassette tape is through the cassette tape hole at cylinder seat two ends and around reservoir, the pivot pin fastener constructions of cassette tape end is fastened to cassette tape and cylinder seat on reservoir, by the hold-down bolt hole on bolt arrangement and cylinder seat, reservoir is in place.
