Abstract
The utility model relates to a seat elevating mechanism, more particularly to a gear elevating mechanism of a driver seat of a rail train. The elevating mechanism comprises a hand wheel, a transmission shaft connecting the hand wheel, a driving bevel gear wheel arranged at one end of the transmission shaft, a lead screw, a driven bevel gear wheel arranged on the lead screw, a lead screw sleeve arranged under the lead screw, and an auxiliary mechanical spring sleevedly arranged outside the lead screw sleeve. According to the utility model, two engaged bevel gear wheels are used to drive the lead screw to realize the elevating function of the seat; and when the elevating function is realized, the assisting of the mechanical spring is utilized to enable the lifting of the seat to be carried out with less labor. Besides, the provided elevating mechanism has advantages of simple and reasonable structure, convenient usage, rapid and smooth elevating, high reliability and low maintenance cost and the like.
Description
Technical field
The utility model relates to a kind of seat riser, a kind of specifically track train driver's chair gear lifting mechanism.
Background technology
Along with the continuous development of China's economic construction and the progress of science and technology; The track train of China (railway, subway etc.) has realized great-leap-forward development; Extensive railway and metro construction efficiently advance; A collection of main construction is constructed and put into operation in succession, and technology innovation is obtained a collection of new great achievement, and high speed railway, subway project construction and international cooperation make important progress.
In order to adapt to the new situations of track train great-leap-forward developments such as railway and subway, traditional in-vehicle device facility can't satisfy the needs of form development.The elevating function of traditional track train driver's chair all adopts the compressed gas spring to realize, goes up and down rapidly, but because the reliability of the restriction gas spring of structure is not high, frequent quality defects, maintenance cost is too high.
Summary of the invention
The purpose of the utility model is to provide a kind of simple and reasonable, goes up and down rapidly freely, and reliability is higher, the track train driver's chair gear lifting mechanism that maintenance cost is low.
The purpose of the utility model is to realize like this; This seat gear lifting mechanism comprises handwheel, connects the transmission shaft of handwheel, be arranged on transmission shaft one end active conical gear, leading screw, be arranged on driven bevel gear on the leading screw, be arranged on screw set below the leading screw, be sleeved on the power-assisted mechanical spring of thick stick cover outside.
Described active conical gear is meshed with driven bevel gear, is processed with trapezoidal outside thread on the leading screw, is processed with trapezoidal internal thread on the screw set, and leading screw and screw set are threaded.
The utlity model has following advantage and good effect
1, the utility model simple and reasonable, easy to use, go up and down rapidly freely, reliability is higher, maintenance cost is low.
2, the utility model utilizes the auxiliary of mechanical spring to make the seat rising more laborsaving when realizing the function that raises through the elevating function of two intermeshing cone gear-driven leading screws realization seats.
Description of drawings
Fig. 1 is a track train driver's chair gear lifting mechanism integral structure scheme drawing.
Fig. 2 is the utility model running condition reference diagram.
The specific embodiment
Shown in accompanying drawing 1: this seat gear lifting mechanism comprises handwheel 1, connects the transmission shaft 2 of handwheel 1, be arranged on transmission shaft 2 one ends active conical gear 3, leading screw 4, be arranged on driven bevel gear 5 on the leading screw 4, be arranged on screw set 6 below the leading screw 4, be sleeved on the power-assisted mechanical spring 7 that thick stick overlaps 6 outsides.
Described active conical gear 3 is meshed with driven bevel gear 5, is processed with trapezoidal outside thread on the leading screw 4, is processed with trapezoidal internal thread on the screw set 6, and leading screw 4 is threaded with screw set 6.
By accompanying drawing 1, shown in 2: the rotation through handwheel 1 during use drives transmission shaft 2 rotations; Thereby the active conical gear 3 that drives transmission shaft 2 other ends rotates; Initiatively conical gear 3 drives driven bevel gear 5 rotations through the ingear mode; Driven bevel gear 5 drives leading screws 4 and rotates, and through the elevating function of the trapezoidal outside thread on the leading screw 4 with the realization of the trapezoidal internal thread on the screw set 6 seat 8, is sleeved on the power-assisted mechanical spring 7 that thick stick overlaps 6 outsides and makes the elevation process of seat 8 more laborsaving.
