Abstract

The utility model discloses an extensible guardrail of a railway tanker, and aims at providing a two-section extensible railway for solving the problem that when the height of the guardrail does not exceed the limit during the tanker runs, and the operator stands on the walking board for operation, the upper section of the guardrail can be drawn out upwards to cause the height of the whole railway to be not less than 90mm, so as to ensure the safety of the operator. The extensible guardrail is composed of an upper bracket and a lower bracket and is characterized in that a guiding board is arranged on a supporting foot of the lower bracket, a supporting foot of the upper bracket passes through a guiding hole of the guiding board and moves up and down along the lower bracket; a plug hole is arranged on the supporting foot of the upper bracket, the other plug hole is also arranged on the corresponding position of the lower supporting foot, the upper supporting foot is connected with the lower supporting foot into a whole by reeving a bolt through the plug holes. The utility model is mainly used as the extensible guardrail of the railway tanker.

Description

The telescopic guardrail of tank car

Technical field

The utility model relates to a kind of guardrail, relates in particular to the telescopic guardrail of a kind of tank car.

Background technology

The height of tank car guardrail is normally fixed, but when practice, the customer requirements personnel stand in the limp and operate, the height of guardrail must not be lower than 900mm, and is in this case, changeless if the height of guardrail remains, so in height just beyond the mark, therefore, must study a kind of boundary that when tank car moves, is no more than, and guardrail height can be increased to the technology that is not less than 900mm when personnel stand in the limp operation.

Summary of the invention

The purpose of this utility model is to provide a kind of tank car telescopic guardrail, to solve above-mentioned technical requirements.

Technical solution of the present utility model is: with the guardrail of tank car be improved to two sections telescopic, generally, above one section be in full state, and use latch locking, guarantee highly to be no more than boundary, and above when having personnel to stand in the limp operation one section can upwards extract out, guardrail height can be increased to be not less than 900mm, and use latch locking.

The utility model comprises upper bracket and lower bracket, it is characterized in that: on the leg 2 of described lower bracket 4, be provided with guide plate 1, the leg 8 of upper bracket 3 passes the

pilot hole

10,10 of guide plate 1 ' move up and down along lower support leg 2; On the leg 8 of described upper bracket 3, have jack 9,9 ', on the correspondence position of lower support leg 2, also have jack, last leg 8 and lower support leg 2 pass jack 9,9 ' link into an integrated entity by latch 6.

On the described lower support leg 2, also be provided with restriction and go up the positioning plate 5 that leg 8 sinks, the lower end of last leg 8 be provided with limit the positioning plate 5 of scurrying on it '.

The utility model has the advantages that: this two sections telescopic guardrails, solved tank car when operation, it highly is no more than boundary, and personnel stand in when operating in the limp, can upwards extract out for one section above it, make guardrail height be not less than 900mm, and use latch locking, thereby guaranteed the safety of operating personal.

Among the figure: the 1-guide plate, the 2-lower support leg, the 3-upper bracket, the 4-lower bracket, the 5-lower limiting board, 5 '-the upper limit plate, the 6-latch, 7-latch chain, the last leg of 8-, 9,9 '-last jack, 10,10 '-pilot hole, 11,11 '-the latch putting hole, 12,12 '-following jack.

The specific embodiment

Below in conjunction with accompanying drawing the utility model and the specific embodiment thereof are described in further detail.

Referring to accompanying drawing 1-3, the utility model comprises upper bracket and lower bracket, it is characterized in that: on the leg 2 of described lower bracket 4, be provided with guide plate 1, the leg 8 of upper bracket 3 passes the

pilot hole

Generally, upper bracket 3 is full state, have only when operating in the limp of personnel at tank car, just upper bracket 3 is extracted out, make guardrail height be not less than 900mm, at this moment, should be with cooresponding jack on jack 9,9 ' aligning lower support leg 2 of going up on the leg 8, insert latch 6 lockings then, leg 8 and lower support leg 2 are linked into an integrated entity.Last leg 8 all the time the

pilot hole

10,10 of guide plate 1 ' control under, move up and down along lower support leg 2, when putting 3 on the shelf need put down the time, must at first extract latch 6 out, and place it in latch putting hole 11,11 on the guide plate 1 ' in, in order to avoid tank car when operation latch rocks, go up leg 8 then and be displaced downwardly to lower limiting board 5 places along lower support leg 2, make that jack 12,12 ' again usefulness latches 6 lock under jack 9,9 ' alignings.Lower limiting board 5 restrictions are gone up leg 8 and are sunk upper limit plate 5 ' then limit to go up on the leg 8 and scurry.Four angles of whole guardrail are total to be no less than 8 guide plates, 8 blocks of upper limit plates and 4 lower limiting boards, and guide plate 1 and lower limiting board 5 can be welded on the lower support leg 2, upper limit plate 5 ' then the be welded on lower end of leg 8.

Claims

1. telescopic guardrail of tank car, comprise upper bracket and lower bracket, it is characterized in that: on the leg (2) of described lower bracket (4), be provided with guide plate (1), the pilot hole (10,10 ') that the leg (8) of upper bracket (3) passes guide plate (1) moves up and down along lower support leg (2); On the leg (8) of described upper bracket (3), have jack (9,9 '), on the correspondence position of lower support leg (2), also have jack, last leg (8) and lower support leg (2) pass jack (9,9 ') by latch (6) and link into an integrated entity.

2. by the described guardrail of claim 1, it is characterized in that on the described lower support leg (2) that also be provided with restriction and go up the positioning plate (5) that leg (8) sinks, the lower end of last leg (8) is provided with limits the positioning plate (5 ') of scurrying on it.
