Description
Technical field
The invention belongs to the fire fighting device technical field, be specifically related to a kind of moving mechanism for opening/closing of the side railway carriage or compartment couplet on the door of fire fighting truck.
Background technology
Such as industry the reason of knowledge; In the compartment of fire fighting truck envelope, be placed with all kinds of disaster relief equipment such as generator, water pump and various break-in tools or the like usually; When after the responding and after arriving at disaster relief scene; Take various equipment for the ease of the fire fighter, need in time quickly the side railway carriage or compartment door on left side and/or right side to be opened.And after disaster relief task is accomplished and various equipment are returned, need side railway carriage or compartment door be closed again.
Previously, the unlatching of offside railway carriage or compartment door or close by fire fighter manual operations not only increases fire fighter's workload, and takies fire fighter's quality time.
The side door-opening mechanism of the fire fighting truck that utility model patent notice of authorization CN200977357Y provides utilizes the keying of hydraulic jack driving side railway carriage or compartment door, though this patent scheme can alleviate fire fighter's working strength and the disaster relief time of getting preciousness.But have following drawback: at first, the patent scheme is suitable for the flap door, and the flap door needs enough spaces in the opening process as spreading the wings, yet in the disaster relief occasion of reality, has the situation of limited space unavoidably, the fastidious property of therefore being used; Secondly, when fire fighting truck arrives at disaster relief scene, in case oil cylinder breaks down, the railway carriage or compartment door then can't be opened, and delays the opportunity that the fire fighter takes equipment, cause more can be serious consequence.Perhaps in view of aforementioned 2 drawbacks that are not limited to, normally used fire fighting truck still opens or cuts out side railway carriage or compartment Men Weizhu with the fire fighter mostly by hand.
The lanar four rod mechanism that the car door open-shut linkage mechanism that notice of authorization CN201024817Y recommends utilizes two covers to link each other can be realized once moving upper and lower two fan doors are opened simultaneously or closed.Yet still have following shortcoming: one of which, under opening, two cover lanar four rod mechanisms can be taken equipment to the fire fighter and produced certain interference (obstruction); Its two because two cover the remaining each other in connecting state of lanar four rod mechanisms, therefore the unlatching amplitude of upper and lower railway carriage or compartment door is restricted; Its three, open or the balance of closing motion is difficult to ensure.
In view of above-mentioned prior art, the applicant has carried out useful exploration and trial, has found the way of dealing with problems, and the technical scheme that will introduce below produces under this background.
Summary of the invention
Task of the present invention is to provide a kind of side railway carriage or compartment couplet on the door that the fire fighter is taken that equipment produces the interference capability influence, the unlatching that helps guaranteeing upper and lower railway carriage or compartment door has enough amplitudes and is of value to the fire fighting truck of the stationarity that embodies switching motion that helps avoid to move mechanism for opening/closing.
Task of the present invention is accomplished like this, and a kind of side railway carriage or compartment couplet on the door of fire fighting truck moves mechanism for opening/closing, and described fire fighting truck includes a compartment envelope; The corresponding both sides of compartment envelope respectively are equipped with the railway carriage or compartment door, railway carriage or compartment door and has the equipment frame column in column chamber down; Equipment frame column is positioned at the accent position, chamber, railway carriage or compartment of compartment envelope and is positioned at the middle part of the length direction of chamber, railway carriage or compartment accent, and the couplet on the door moving mechanism for opening/closing in described side railway carriage or compartment comprises traction wheel, upper and lower pulley, pull rope, carriage, goes up strut and lower supporting rod, and the traction wheel pivot is arranged on the traction wheel seat; The traction wheel seat is fixed on the described inboard of railway carriage or compartment door down; And the position of traction wheel seat on the door of following railway carriage or compartment is corresponding with described equipment frame column, and the top sheave pivot is arranged in the said column chamber, and is positioned at the upper end of equipment frame column; The lower sheave pivot is arranged on the bottom in column chamber; Corresponding with top sheave, an end of pull rope is fixedly connected on the traction wheel, and the other end is being fixedly connected with carriage behind lower sheave and top sheave successively; Carriage slides up and down to be positioned at said column chamber; One end pivoting of last strut is arranged on the equipment frame column and corresponding to the top of said top sheave, and it is hinged to go up the end of the other end and lower supporting rod of strut, and the other end pivotal connection of lower supporting rod is on carriage; Wherein: lower supporting rod and said on the end that is hinged of strut also be equipped with a roller, this roller matches with the described railway carriage or compartment door of going up.
In a concrete embodiment of the present invention, describedly to go up the inboard of railway carriage or compartment door and be installed with a rolling wheel guide rails at position corresponding to described roller, described roller matches with rolling wheel guide rails.
In another concrete embodiment of the present invention; Described carriage comprises travelling carriage, a pair of upper block and a pair of lower tumbler, has extended a upper block seat on the top of travelling carriage, and the bottom has extended wheel stand; The middle part is formed with a lower supporting rod and connects the chamber; And connect at lower supporting rod on the corresponding cavity wall in chamber and respectively offer the lower supporting rod pin shaft hole that a position corresponds to each other, a pair of upper block pivot is arranged on the upper block seat, and contacts with the chamber wall in the column chamber of said equipment frame column; A pair of lower tumbler pivot is arranged on the lower tumbler seat; And contact equally with the chamber wall in the column chamber of said equipment frame column, described lower supporting rod and travelling carriage pivotal connection, described pull rope is fixedly connected with the upper block seat.
In another concrete embodiment of the present invention; One end of said lower supporting rod and said travelling carriage pivotal connection constitutes a lower supporting rod kink; On this lower supporting rod kink, offer one first pivot hole; Wherein: the lower supporting rod kink is insinuated into said lower supporting rod by way of the column chamber and connects in the chamber, and by first bearing pin through said lower supporting rod pin shaft hole and travelling carriage pivotal connection.
In another concrete embodiment of the present invention; A described end of going up strut and said equipment column pivotal connection constitutes strut kink on; On this, offer one second pivot hole on the strut kink, and upward the strut kink probes into the column chamber by second bearing pin and equipment frame column pivotal connection.
Also have among the concrete embodiment of the present invention, described pull rope is a wire rope.
Technical scheme provided by the invention has been owing to adopted above-mentioned design, and when outwards dragging when drawing down the railway carriage or compartment door, once action can be opened upper and lower railway carriage or compartment door simultaneously, and vice versa; Because for carrier is set, therefore there is not the interference situations the when fire fighter taken equipment with equipment frame column in all component after unlatching; The unlatching amplitude of upper and lower railway carriage or compartment door is big; Stationarity when opening and closing upper and lower railway carriage or compartment door is good.
