Abstract
The embodiment of the utility model provides an adjustable lift buffering device. The adjustable lift buffering device comprises a vertically-placed buffering oil cylinder (1), a throttling valve (2), a check valve (3) and an energy accumulator (4), wherein a piston rod (11) of the buffering oil cylinder (1) stretches out from the upper end and the top end of the buffering oil cylinder (1) is provided with a ram (5); a rodless cavity of the buffering oil cylinder (1) is internally provided with a spring buffer (12); the throttling valve (2) is connected with the check valve (3) in parallel and then is connected with the buffering oil cylinder (1) and the energy accumulator (4); and a connection direction of the throttling valve (2) allows hydraulic oil of the energy accumulator (4) to flow into the buffering oil cylinder (1) of a hydraulic cylinder through the check valve (3). According to the adjustable lift buffering device disclosed by the utility model, the size of buffering and damping can be accurately adjusted; the buffering effect is good; and the condition of hard impact can be stably avoided.
Description
Technical field
The utility model relates to a kind of Design of Mechanical Structure technical field, relates in particular to a kind of elevator buffer device that can regulate.
Background technology
To need stop the time, car need to rely on shock absorber that its pulsation-free is stopped in the descending process of elevator.All one group of spring to be set complete pooling feature at present.Its shortcoming is that the damping of buffering can't be regulated, and need change different spring assembly for the car of different sizes.Use inconvenience, and buffering effect is poor, is prone to the situation of rocking or firmly impacting.
The utility model content
The purpose of this utility model is to provide a kind of adjustable elevator buffer device, can adjust accurately the size of buffer damping, and good buffer effect steadily avoids hard situation of impacting to occur.
The purpose of this utility model is achieved through the following technical solutions:
A kind of adjustable elevator buffer device comprises the cushion cylinder 1, flow regulating valve 2, check valve 3 and energy storage 4 of vertical placement;
The piston rod 11 of cushion cylinder 1 stretches out from the upper end, and the top is provided with rams 5;
Be provided with spring bumper 12 in the rodless cavity of cushion cylinder 1;
Is connected cushion cylinder 1 and energy storage 4 after flow regulating valve 2 and check valve 3 is in parallel, the closure of check valve 2 allows the hydraulic oil of energy storage 4 to pass through check valve 2 inflow hydraulic actuating cylinder cushion cylinders 1.
Described adjustable elevator buffer device also comprises retractable guard 6, and retractable guard 6 is placed in the section of the stretching out outside of piston rod 11.
Described adjustable elevator buffer device also comprises base plate 7, and described cushion cylinder 1 is fixed on base plate 7.
Can be found out by the technical scheme that above-mentioned the utility model provides, a kind of adjustable elevator buffer device that the utility model embodiment provides can be adjusted the size of buffer damping accurately, and good buffer effect steadily avoids hard situation of impacting to occur.
Description of drawings
In order to be illustrated more clearly in the technical scheme of the utility model embodiment, during the below will describe embodiment, the accompanying drawing of required use is done to introduce simply, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skill in the art, under the prerequisite of not paying creative work, can also obtain other accompanying drawings according to these accompanying drawings.
The structural representation of adjustable elevator buffer device that Fig. 1 the utility model embodiment provides.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on embodiment of the present utility model, those of ordinary skills belong to protection domain of the present utility model not making the every other embodiment that obtains under the creative work prerequisite.
Below in conjunction with accompanying drawing, the utility model embodiment is described in further detail.
Embodiment
As shown in Figure 1, a kind of adjustable elevator buffer device comprises the cushion cylinder 1, flow regulating valve 2, check valve 3 and energy storage 4 of vertical placement; Flow regulating valve 2 allows the hydraulic oil of energy storage 4 to flow into hydraulic actuating cylinder cushion cylinders 1 by check valve 2 with check valve 3 rear the be connected logical hydraulic fluid port of cushion cylinder 1 and the logical hydraulic fluid port of energy storage 4 in parallel, the closure of check valve 2.The cushion cylinder 1 here is single acting oil cylinder.Described cushion cylinder 1 is fixed on base plate 7.
The piston rod 11 of cushion cylinder 1 stretches out from the upper end, and the top is provided with rams 5; Simultaneously, the section of stretching out of piston rod 11 outside is also overlapped and retractable guard 6 is arranged, protection cushion cylinder 1 and piston rod 11.Be provided with spring bumper 12 in the rodless cavity of cushion cylinder 1.
Principle of work of the present utility model is as follows,
The grand contact to the bottom rams 5 under car, on apply piston bar 11, because being connected with flow regulating valve 2, cushion cylinder 1 also can use an one-way throttle valve to replace flow regulating valve 2 and check valve 3 with check valve 3(), spring bumper 12 is installed in simultaneous buffering oil cylinder 1, piston rod 11 is not to descend immediately, and because the hydraulic oil of cushion cylinder 1 reaches in energy storage 4 by flow regulating valve 3, regulate the openings of sizes of flow regulating valve 3, just can adjust the speed that the piston rod 11 of cushion cylinder 1 moves.Can adjust accurately the size of buffer damping, good buffer effect steadily avoids hard situation of impacting to occur.
Up when car, break away from and to ram after 5, due to the effect of energy storage 4, hydraulic oil arrives the rodless cavity of cushion cylinders 1 by check valve 2, move on piston 13, in the rodless cavity due to cushion cylinder 1, spring bumper 12 is installed simultaneously, makes piston 13 return to original position.
The above; it is only the better specific embodiment of the utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement are within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
