Abstract
The utility model relates to a kind of large arm buffer of car puller.When car puller promotes empty wagons there is to clash into the axial force of the impact force that produces mainly connecting rod in large arm gib head and train gib head, and radial force should be very little, completely in the intensity region that directed connecting rod can bear.A kind of large arm buffer of car puller, its composition comprises: oil hydraulic cylinder (3), piston (5), there is in described oil hydraulic cylinder hydraulic fluid chamber (7), in described hydraulic fluid chamber, there is piston, described piston is by seal ring (8) and hydraulic fluid chamber contact internal walls, be connected (2) with car puller large arm on the left of described piston, described car puller large arm is contacted with oil hydraulic cylinder by dust plug (4), is connected on the right side of described piston by spring (6) with hydraulic fluid chamber inwall.The utility model is applied to the large arm buffer of car puller.
Description
technical field:
the utility model relates to a kind of large arm buffer of car puller.
background technique:
when car puller promotes empty wagons there is to clash into the axial force of the impact force that produces mainly connecting rod in large arm gib head and train gib head, radial force should be very little, completely in the intensity region that directed connecting rod can bear, but in the manufacturing operation of reality, the radial force that during car puller promotion empty wagons, directed connecting rod bears is often very large, causes directed connecting rod at operation process Fracture.
summary of the invention:
the purpose of this utility model is to provide a kind of large arm buffer of car puller.
above-mentioned object is realized by following technological scheme:
a kind of large arm buffer of car puller, its composition comprises: oil hydraulic cylinder, piston, in described oil hydraulic cylinder, there is hydraulic fluid chamber, in described hydraulic fluid chamber, there is piston, described piston is by seal ring and hydraulic fluid chamber contact internal walls, be connected with car puller large arm on the left of described piston, described car puller large arm is contacted with oil hydraulic cylinder by dust plug, is connected on the right side of described piston by spring with hydraulic fluid chamber inwall.
the large arm buffer of described car puller, described car puller large arm left end is connected with go-cart plate.
the beneficial effects of the utility model:
1. the utility model adopts the stroke ratio conventional springs buffer needed for hydraulic buffer to reduce half, when gib head is subject to clashing into, piston rod shrinks, force in hydraulic oil typing accumulator, thus resistivity is produced, in the process of whole shock, the pressure of oil hydraulic cylinder remains certain, produce the cushion effect of a constant size, the gib head that such hydraulic buffer just can be impacted steadily stops, and at the end of impact is formed, car puller large arm is pushed back initial position by spring, hydraulic oil discharges by accumulator, waits for and impacting next time.
the large arm buffer of a kind of car puller of the utility model, in described oil hydraulic cylinder, there is hydraulic fluid chamber, hydraulic oil is full of in oil pocket, in described hydraulic fluid chamber, there is piston, described piston is by seal ring and hydraulic fluid chamber contact internal walls, hydraulic oil in seal ring sealed hydraulic oil pocket, be connected with the large arm of car puller on the left of described piston, the large arm diameter of car puller is large, the moment of flexure that shock produces can be born, the large arm of described car puller is contacted with oil hydraulic cylinder by dust plug, arranging of dust ring can prevent dust etc., be connected with hydraulic fluid chamber inwall by spring on the right side of described piston.In the course of the work, hydraulic oil can heat up, and heat is passed to oil hydraulic cylinder, and go being dispersed in air, kinetic energy is become heat energy, and therefore hydraulic buffer can absorb kinetic energy, and can not have a rebound again phenomenon as elastic buffer.
accompanying drawing illustrates:
accompanying drawing 1 is structural representation of the present utility model.
embodiment:
embodiment 1:
a kind of large arm buffer of car puller, its composition comprises: oil hydraulic cylinder 3, piston 5, there is in described oil hydraulic cylinder hydraulic fluid chamber 7, in described hydraulic fluid chamber, there is piston, described piston is by seal ring 8 and hydraulic fluid chamber contact internal walls, be connected with piston rod 2 on the left of described piston, the large arm of described car puller is contacted with oil hydraulic cylinder by dust plug 4, is connected on the right side of described piston by spring 6 with hydraulic fluid chamber inwall.
the large arm buffer of described car puller, described car puller large arm left end is connected with go-cart plate 1.
Claims (2)
1. the large arm buffer of a car puller, its composition comprises: oil hydraulic cylinder, piston, it is characterized in that: in described oil hydraulic cylinder, there is hydraulic fluid chamber, in described hydraulic fluid chamber, there is piston, described piston is by seal ring and hydraulic fluid chamber contact internal walls, be connected with car puller large arm on the left of described piston, described car puller large arm is contacted with oil hydraulic cylinder by dust plug, is connected on the right side of described piston by spring with hydraulic fluid chamber inwall.
2. the large arm buffer of car puller according to claim 1, is characterized in that: described car puller large arm left end is connected with go-cart plate.
