Abstract
The utility model discloses a conical steering damping structure of a forklift handle. The conical steering damping structure comprises a cylindrical handle fixing base. A handle support shaft is rotationally arranged in the handle fixing base through an upper bearing and a lower bearing. A steering handle is arranged on the top of the handle support shaft. The handle support shaft is sleeved with an upper nylon ring and a lower nylon ring which are matched with each other. The lower nylon ring is provided with a taper hole. The annular outer wall of the upper nylon ring is conical. The narrow end of the upper nylon ring is embedded in an annular taper hole formed between the lower nylon ring and the handle support shaft. The lower end face of the lower nylon ring is fixed to the inner side face of the lower bearing. The conical steering damping structure is simple and reasonable in design; when a forklift is driven on an unsmooth road surface, due to the fact that a damping mechanism is added to the steering handle, the unstable direction caused when the steering handle of the forklift swings back and forth can not occur, and driving safety can not be influenced; due to the fact that the operation hand feeling of a driver is better under the damping condition, working fatigue of the driver is reduced.
Description
technical field:
The utility model relates generally to fork truck technical field, relates in particular to a kind of fork truck handgrip and turns to taper damping mechanism.
background technology:
Along with scientific and technological development and people more and more higher to the comfortable pursuit of working, the original mechanical steering of pallet class transport trolley, because steering effort is larger, the effort that operates, long period of operation is very tired out, the pallet class transport trolley that configuration electricity turns to is more and more.There are two kinds of situations in original handlebar steering mechanism, and the one, there is no cornering resistance mechanism, during operation, handgrip easily swings back and forth, and drives unstable; The 2nd, configuration turns to damping mechanism, use be a pair of friction lining, although can have effect after adjusting, along with the wearing and tearing in use procedure, regularly adjust, be not easy to operation and maintenance.It is adjustable that the utility model solves cornering resistance exactly, after once mounting, need not adjust and safeguard, greatly increases ease for use and non-maintaining feature.
utility model content:
The utility model object is exactly in order to make up the defect of prior art, provides a kind of fork truck handgrip to turn to taper damping mechanism, and its convenient operation increases operator's traveling comfort, the convenience of use.
The utility model is achieved through the following technical solutions:
A kind of fork truck handgrip turns to taper damping mechanism, include the handgrip permanent seat of tubular, in described handgrip permanent seat, by upper and lower bearing, be rotatablely equipped with handle support base axle, described handle support base axle top is provided with and turns to handgrip, it is characterized in that: on described handle support base axle, be set with the upper and lower nylon ring cooperatively interacting, lower nylon ring is with taper hole, the annular outer wall of upper nylon ring is taper, the narrow end setting-in of upper nylon ring enters in the annular taper hole forming between lower nylon ring and handle support base axle, and the lower surface of lower nylon ring is fixed on lower bearing medial surface.
Fork truck handgrip turns to a taper damping mechanism, it is characterized in that: on described handle support base axle, between head bearing and upper nylon ring, be set with coil spring.
Fork truck handgrip turns to a taper damping mechanism, it is characterized in that: the bottom fixed cover of handle support base axle is equipped with driving gear; One side of handgrip permanent seat is provided with installation otic placode, installs on otic placode sensor is installed, and the input shaft lower end of sensor is stretched out and installed outside otic placode, and the external part fixed cover of input shaft is equipped with the ring gear with driving gear engaged transmission.
The tapering of upper and lower nylon ring is 60 degree.
When driving pallet class transport trolley, hold steering handle, control fork truck travel direction, by swinging, operator's intention is conducted to controller by sensor, send instruction car is turned to.In the process of swinging, resistance when 60 right degree taper nylon ring increases of use one assembly turn to, is convenient to control better handgrip direction.Use coil spring, can automatically adjust the size of resisting moment, the wearing and tearing of auto-compensation nylon ring.
The utility model is by a pair of 60 degree taper nylon rings, the resisting moment when increasing handgrip and turning to, and person has feel when operation fork truck to make forklift operator, avoids handgrip to swing back and forth causing the fork truck shakiness of travelling when forklift-walking; The utility model, by a helical spring thrust, is adjusted the size of resisting moment; 60 degree taper nylon ring and helical spring being used in conjunction with, resisting moment when handgrip is turned to has self-compensating function, and the wearing and tearing because of nylon ring do not reduce resisting moment; Whole mechanism profile is small and exquisite, and space hold is little, is particularly applicable to have pallet carrying class fork truck that electric turning function handgrip turns to, pallet stacking car etc.
The utility model has the advantages that:
The utility model is simple in structure, reasonable in design, and when fork truck travels not too smooth on road surface time, owing to turning to handgrip to increase damping mechanism, the handgrip that turns to of fork truck can not swing back and forth, and causes direction unstable, affects driving safety; And in the situation that having damping, driver's operation feel is better, also reduces the fatigue of chaufeur work.
accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
the specific embodiment:
Referring to accompanying drawing.
A kind of fork truck handgrip turns to taper damping mechanism, include the handgrip permanent seat 10 of tubular, in described handgrip permanent seat 10, by upper and lower bearing 3, be rotatablely equipped with handle support base axle 2, described handle support base axle 2 tops are provided with and turn to handgrip, on handle support base axle 2, be set with the upper and lower nylon ring 5,6 cooperatively interacting, lower nylon ring 6 is with taper hole, the annular outer wall of upper nylon ring 5 is taper, the narrow end setting-in of upper nylon ring 5 enters in the annular taper hole forming between lower nylon ring 6 and handle support base axle 2, and the lower surface of lower nylon ring 6 is fixed on lower bearing 3 medial surfaces.
On handle support base axle 2, between head bearing 3 and upper nylon ring 5, be set with coil spring.
The bottom fixed cover of handle support base axle 2 is equipped with driving gear 7; One side of handgrip permanent seat 10 is provided with installation otic placode, installs on otic placode sensor 9 is installed, and the input shaft lower end of sensor 9 is stretched out and installed outside otic placode, and the external part fixed cover of input shaft is equipped with the ring gear 8 with driving gear 7 engaged transmission.
