Abstract
The utility model relates to a buffer, and particularly relates to a hydraulic oil buffer. The utility model provides a hydraulic oil buffer which comprises an upper fixing plate and a lower fixing plate, wherein the upper fixing plate and the lower fixing plate are provided with external threads matching with external threads of an oil cup. The hydraulic oil buffer comprises a pressing rod and an oil cup, wherein the pressing rod is inserted into the oil cup and is capable of moving up and down; the hydraulic oil buffer also comprises the upper fixing plate and the lower fixing plate which are provided with internal threads; the oil cup is provided with the external threads; and the internal threads are matched with the external threads. The height of the hydraulic oil buffer can be adjusted, so that the hydraulic oil buffer can be installed simply and reasonably and conveniently and rapidly, and is very beneficial for regulation of a breaker.
Description
Technical field
The utility model relates to a kind of buffer, specifically, relates to a kind of hydraulic oil buffer.
Background technique
Hydraulic oil buffer of the prior art generally all comprises depression bar, lubricating cup, support, fixed plate, and depression bar inserts in the lubricating cup, can move up and down; Support is used for supporting buffer; But hydraulic oil buffer of the prior art generally all is provided with a fixed plate, thus the position of hydraulic oil buffer and highly all fixing, like this; If it is bad that hydraulic oil buffer and circuit breaker cooperate; Only take to adjust the method for the position of hydraulic oil buffer, have following defective: 1. pair installation dimension required precision is high, has improved machining cost; 2. Installation and Debugging and use are inconvenient; 3. reliability is relatively poor.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of upper mounted plate and bottom plate of being provided with, the externally threaded hydraulic oil buffer that the outside thread of upper mounted plate and bottom plate setting and lubricating cup cooperates.
The technological scheme of the hydraulic oil buffer of the utility model is such: it comprises depression bar, lubricating cup; Depression bar inserts in the lubricating cup and can move up and down, and it also comprises upper mounted plate and bottom plate, and upper mounted plate and bottom plate are provided with internal thread; Outside thread is set on the lubricating cup, and internal thread and outside thread cooperate.
It also comprises support the utility model, and support is arranged between upper mounted plate and the bottom plate, the hole that setting and lubricating cup cooperate in the middle of the support.
The height of the hydraulic oil buffer of the utility model can be adjusted, thus install fairly simple rationally and convenient and swift, and be very beneficial for the debugging of circuit breaker.
Description of drawings
Fig. 1 is the structural representation of the hydraulic oil buffer of the utility model in the breaker open operation initial position;
Fig. 2 is that the hydraulic oil buffer of the utility model begins acting structural representation.
1: circuit breaker frame, 2: groove pin, 3: roller, 4: connecting lever, 5: circuit breaker main shaft, 6: depression bar, 7: lubricating cup, 8: support, 9: bottom plate, 10: upper mounted plate.
Embodiment
It comprises depression bar, lubricating cup the hydraulic oil buffer of the utility model, and depression bar inserts in the lubricating cup and can move up and down, and it also comprises upper mounted plate and bottom plate, and upper mounted plate and bottom plate are provided with internal thread, and outside thread is set on the lubricating cup, and internal thread and outside thread cooperate.It also comprises support the utility model, and support is arranged between upper mounted plate and the bottom plate, the hole that setting and lubricating cup cooperate in the middle of the support.
The purpose of the utility model is achieved in that circuit breaker frame 1, roller 3 are connected through groove pin 2 with connecting lever 4, and roller 3 can rotate around groove pin 2; Circuit breaker main shaft 5 welds together with connecting lever 4; Depression bar 6 inserts in the lubricating cup 7 of hydraulic oil buffer, can move up and down; Lubricating cup 7 is processed with outside thread, and support 8 has the hole, and lubricating cup 7 can therefrom pass, and is processed with internal thread at bottom plate 9 and upper mounted plate 10, and bottom plate 9 and upper mounted plate 10 are screwed on the lubricating cup 7, and support 8 is clipped in the middle, and realizes fastening.
Vacuum circuit breaker is in the separating brake process, and circuit breaker main shaft 5 clockwise directions rotate, and drive connecting lever 4 simultaneously and rotate, when arriving position shown in Fig. 1-2, roller 3 contact depression bars 6, the hydraulic oil buffer begins to play the splitting lock cushioning effect.
Vacuum circuit breaker separating brake novel hydraulic damping mechanism is simple in structure; Assemble very easyly, the hydraulic oil buffer plays the spacing effect of breaker open operation in addition, and its position directly influences circuit breaker and opens distance; Screw fixation method, adjustable height are adopted in the installation of hydraulic bjuffer.Conventional separating brake oil dashpot adopts the base plate fixed installation mostly, and is highly non-adjustable, very high to the installation dimension requirement, relates to the part component of machine is carried out the machining finishing again, wastes time and energy.
