Abstract
The utility model provides a roof protection rail with raising and lowering functions, include the rail, be fixed in the stand base on the transport vechicle jar body and connect the stand between stand base and rail, but swing joint between stand base and the stand, be connected with the telescoping device on the cylinder of one of stand. The utility model discloses before operating personnel need go up roof operation, open rail control switch and rise the rail is automatic, after the operation, get off and close control switch, the automatic whereabouts of rail, fundamentally has avoided the appearance of the unshielded state of roof operation, the effectual security that improves roof operation activity has replaced the operation of manual lift rail as power with the cylinder, greatly reduced roof operation personnel work load and improved work efficiency.
Description
Technical field
The utility model relates to a kind of roof protective fence with elevating function, belongs to field of mechanical technique.
Background technology
In prior art, abhiseca terrain clearance is greater than to the pot type fuel tanker of 2 meters, as filling car, fuel tanker, refueling semitrailer, fortune oil superimposed trailer, all set up defences guard fence in its abhiseca service platform both sides.Common protective fence does not have power and control setup, roof operating personnel needs hand-operated lifting protective fence, from roof operating personnel to carrying out fence elevation operation, to perform that fence step-down operation leaves roof to operating personnel be unshielded state, has certain danger.
Utility model content
Technical problem to be solved in the utility model is, for the above security hidden trouble existed, and a kind of roof protective fence with elevating function of design.
In order to solve above technical matters, the utility model provides a kind of roof protective fence with elevating function, the column comprising fence, be fixed on the upright post base on transport vehicle tank body and be connected between upright post base and fence; It is characterized in that: described upright post base is connected with movable between column, and the cylinder of one of described column is connected with retractor device.
The technical scheme that the utility model limits further is:
Further, described upright post base is connected by bearing pin and pin with column.
Further, described retractor device is cylinder, and described cylinder one end is connected with column, and the other end is connected with the cylinder pedestal be fixed on tank body.
Further, also comprise standpipe, 3-position 4-way scavenge valve is installed between described standpipe and cylinder.
Further, also comprise cylinder lift control switch, described master cock is arranged on transport trolley control box.
Further, described retractor device is gas spring.
The beneficial effects of the utility model are: a kind of protective fence possessing elevating function that the utility model provides, it on operating personal needs roof operation before, open fence master cock fence is risen automatically, after the end of job, get off and master cock closed, fence falls automatically, fundamentally avoid the appearance of the unshielded state of roof operation, effectively raise the safety of roof activity, instead of the operation of hand-operated lifting fence with cylinder as power, greatly reduce the work capacity of roof operating personnel and improve work efficiency.

Detailed description of the invention
embodiment 1
A kind of roof protective fence with elevating function that the present embodiment provides, as Figure 1-3: the column 2 comprising fence 1, be fixed on the upright post base 3 on transport vehicle tank body and be connected between upright post base 3 and fence 1; Described upright post base 3 is connected by bearing pin 8 and pin 9 with between column 2.The cylinder of one of described column 2 is connected with cylinder 4, and described cylinder 4 one end is connected with column 2, and the other end is connected with the cylinder pedestal 5 be fixed on tank body.Be that propulsion source drives fence lifting with cylinder; The mode of operation of control cylinder is carried out, to reach the object controlling fence lifting by Pneumatic valve.
Also comprise standpipe 6, between described standpipe 6 and cylinder 4,3-position 4-way scavenge valve 7 is installed.Pneumatic valve by the mode of operation of air-channel system control cylinder, then drives rising and falling of column by cylinder, thus controls the lifting of protective fence.
Also comprise cylinder lift control switch, described master cock is arranged on transport trolley control box.The front opening Pneumatic valve of the upper tank deck operation of staff, rises fence, closes Pneumatic valve and fallen by fence after operation is complete.
In addition to the implementation, the utility model can also have other embodiments, as cylinder is replaced by gas spring etc.All employings are equal to the technical scheme of replacement or the formation of equivalent transformation form, all fall into the protection domain of the utility model requirement.
