Combined with the ladder for linkage, elevation of the guardrail can be controlled by an operator on ground by the ladder. The safety guardrail has the advantages of safety, labor-saving, simple and reliable operation, and low cost.
Description
Technical field
The utility model relates to a kind of safety barrier, especially relates to a kind of up-down movable safety barrier.
Background technology
Present stage because the needs of work safety aspect, at the tank car top or other service platform top need be equipped with safety barrier.With the tank car is example, and the charging hole of tank car generally is arranged in the top, and the workman need be by arriving the tank car top when feeding operation on the cat ladder of placing vertically.In order to guarantee safety, arrange monolateral or bilateral aisle, aisle arranged outside safety barrier usually along its length at the tank car top.The tank deck safety barrier is divided into fixed type and mobile lifting formula: owing to be subjected to the restriction of car load height, the fixed type guardrail is generally shorter, and the safety precaution effect is relatively poor; Mobile lifting formula safety barrier commonly used generally adopts cylinder to control its lifting or operating personal and stands in tank deck and with hand guardrail is mentioned or put down, during driving safety barrier is put down, do not influence the car load height, during the charging operation safety barrier is risen to certain height, play the safety precaution effect, by the structure of cylinder control guard bar lifting, owing to contain cylinder component and control system thereof, so cost increases, structure is also complicated; Mention or put down guardrail if operating personal stands in tank deck, then increased unsafe factor again newly.
The utility model content
The purpose of this utility model is the problem at above-mentioned existence, and a kind of up-down movable safety barrier is provided.This up-down movable safety barrier utilizes the lifting of connecting rod mechanism control tank deck safety barrier, and is simple in structure, easy to operate safe and reliable again.
In order to achieve the above object, the utility model provides a kind of up-down movable safety barrier, and it comprises:
Horizontal bar bar, perpendicular railing interconnect by rotating shaft;
Fixed support is arranged on car body or service platform top, is connected with perpendicular railing by rotating shaft;
Fixing cat ladder is arranged on the rear end of car body or service platform, uses for the user and climbs to car body or service platform top;
The upset cat ladder is connected in the fixedly bottom of cat ladder by rotating shaft;
Also comprise linkage, this linkage is respectively with the upset cat ladder and be arranged at car body or the perpendicular railing of service platform rear end is connected, drives to erect railing and rotate up until being vertical state when the upset cat ladder moves downward.
Up-down movable safety barrier described in the utility model under the height-limited situation of vehicle ', can put down guardrail, and vehicle is superelevation not; When vehicle is feeded operation in factory, guardrail can be risen, play the safety precaution effect.Owing to combine interlock with cat ladder, operating personal stands in ground and controls the lifting of safety barrier by cat ladder, and both safety labor-saving was simple and reliable again, and cost is not high yet.
Description of drawings
Fig. 1 is the described up-down movable safety barrier of the utility model first embodiment.
Fig. 2 is the described up-down movable safety barrier of the utility model second embodiment.
The major part nomenclature
1 horizontal bar bar, 2 perpendicular railings
3 fixed supports, 4 connecting rods
5 fixing cat ladder 6 upset cat ladders
7,8,9,10,11 rotating shafts, 12 car bodies or service platform
13 connecting portions, 14 steel ropes
15 fixed pulleys, 16 retracing springs
The specific embodiment
An embodiment of the present utility model has outstanding connecting portion 13 for described up-down movable safety barrier includes horizontal bar bar 1, perpendicular railing 2, fixed support 3, connecting rod 4, fixedly cat ladder 5, upset cat ladder 6 and rotating shaft 7,8,9,10,11 on the perpendicular railing that is arranged at car body or service platform rear end.At first, fixed support 3 is arranged at car body or service platform top, and fixedly cat ladder 5 is arranged at the rear end of car body or service platform, uses for the user and climbs to car body or service platform top.Horizontal bar bar 1 is connected by rotating shaft 7 with perpendicular railing 2, and perpendicular railing 2 is connected with fixed support by rotating shaft 8 again.Upset cat ladder 6 is connected in the fixedly bottom of cat ladder by rotating shaft 9.Connecting rod 4 is connected with the cat ladder 6 that overturns by connecting rotating shaft 10, is connected by the connecting portion 13 that is had on rotating shaft 11 and the perpendicular railing that is arranged at car body or service platform rear end again.When upset cat ladder 6 around the shaft 9 when rotating up, drivening rod 4 upward movements.This moment, connecting rod 4 drive connecting portions 13 moved, thereby perpendicular railing 28 is rotated down around the shaft.Horizontal bar bar 1 and perpendicular railing 2 drop on the fixed support 3 in level under the self gravitation effect, and the car load height is unaffected.When upset cat ladder 6 around the shaft 9 when being rotated down, drivening rod 4 moves downward.This moment, connecting rod 4 drive connecting portions 13 moved, thereby perpendicular railing 28 is rotated up up to being vertical state around the shaft, simultaneously horizontal bar bar 1 is the level of state, and the cat ladder 6 that overturns this moment also is vertical shape, as the part of fixing cat ladder 5 on the operator to the tank car top.
Another embodiment of the present utility model includes horizontal bar bar 1, perpendicular railing 2, fixed support 3, fixedly cat ladder 5, upset cat ladder 6, steel rope 14, fixed pulley 15 and rotating shaft 7,8,9 for described up-down movable safety barrier, and at the retracing spring 16 that is arranged between perpendicular railing and car body or the service platform.At first, fixed support 3 is arranged at car body or service platform top, and fixedly cat ladder 5 is arranged at the rear end of car body or service platform, uses for the user and climbs to car body or service platform top.Horizontal bar bar 1 is connected by rotating shaft 7 with perpendicular railing 2, and perpendicular railing 2 is connected with fixed support by rotating shaft 8 again.Upset cat ladder 6 is connected in the fixedly bottom of cat ladder by rotating shaft 9.Steel rope 14 1 ends are connected with perpendicular railing 2, and the other end is connected with upset cat ladder 6 after walking around fixed pulley 15.Perpendicular railing 2 is provided with retracing spring 16.When upset cat ladder 6 around the shaft 9 when rotating up, steel rope 14 loosens.Horizontal bar bar 1 and perpendicular railing 2 are dropping under the effect of retracing spring 16 on the fixed support 3, and the car load height is unaffected.When upset cat ladder 6 around the shaft 9 when being rotated down, drive steel rope 14 and move downward.The perpendicular railing 2 of steel rope 14 drives this moment moves, thereby perpendicular railing 28 is rotated up up to being vertical state around the shaft, simultaneously horizontal bar bar 1 is the level of state, and the cat ladder 6 that overturns this moment also is vertical shape, as the part of fixing cat ladder 5 on the operator to the tank car top.
What need statement is that the above-mentioned utility model content and the specific embodiment are intended to prove the practical application of technical scheme that the utility model provides, and should not be construed as the qualification to the utility model protection domain.Those skilled in the art are in spirit of the present utility model and principle, when doing various modifications, being equal to and replacing or improve.Protection domain of the present utility model is as the criterion with appended claims.
