Description
Technical field
The invention belongs to technical field of electric power construction, more particularly to a kind of novel flat-plate wheel.
Background technology
Flat car is frequently used for since its is simple in structure and load-bearing is preferable for carrying heavy cargo.Especially power train
System, in capital construction, in the work of equipment installation and O＆M maintenance, the frequency of use higher of flat car.Flat car is carried out
Corresponding technological improvement can save the muscle power of flat car user of service, the working efficiency of felevating platform truck, guarantee vehicle
The safety of process is the emphasis of concern.
Overwhelming majority platform vehicle wheel is most easy car wheel structure at present, when transporting goods upward slope, once strength is not
Enough cause to slip out of the hand, the downward hill wash of trolley can be caused dynamic, the person, cargo, trolley is easy to cause and causes to damage, safety in production is caused
It seriously affects.Few wheels band service brake function flat car cannot be checked automatically since service brake can only be manually opened and closes,
Also it will appear above-mentioned phenomenon.
Invention content
The present invention is directed to overcome the deficiencies of existing technologies, in view of the above-mentioned problems, providing a kind of novel flat-plate wheel.With knot
Structure is simple, automatic dead-locking function.
Have the characteristics that of simple structure and low cost, safe and reliable.
In order to solve the above technical problem, the present invention provides following technical schemes：
A kind of novel flat-plate wheel includes mainly wheel 1, ratchet 2, pawl 3, connecting rod 4, tightening nut 5, and feature exists
In：Ratchet 2 is fixedly mounted in 1 side of wheel, and ratchet 2 is rotated together with wheel 1, ratchet 2 radius ratio wheel, 1 radius is small；Vehicle
Connecting rod 4 is connected between wheel and car body, connecting rod 4 is installed on the car body by screw, passes through tightening nut in connecting rod 4
5 are equipped with two pawls that can be rotated 3；Ratchet is equipped with adjusting elasticity part.
Preferably, ratchet 2, pawl 3, connecting rod 4, tightening nut 5 use Fine Steel Casting iron structure, on the one hand ensure weight
It is relatively light, on the other hand ensure that performance is firm.
Preferably, connecting rod 4 is designed using curved bar, ensures that pawl 3 has good angle that can block ratchet.
Compared with prior art, the present invention has following advantageous effect：
It is an advantage of the invention that 1. when can solve flat car and going up a slope, the dynamic problem of the downward hill wash of trolley.Use the equipment
When upward slope, ratchet can be automatically locked wheel, prevent trolley from roll-off occur, can save the muscle power of flat car user of service,
The working efficiency of felevating platform truck.2. the device structure is simple simultaneously, performance is firm, can mass produce, while avoiding passing
Many safety accidents that system trolley occurs in transportational process are capable of providing corresponding guarantee to safety in production.
Description of the drawings
Fig. 1 is the schematic diagram of novel flat-plate wheel of the present invention.
Fig. 2 is the assembling schematic diagram of novel flat-plate wheel of the present invention.
Specific implementation mode
Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, it should be understood that preferred reality described herein
Apply example only for the purpose of illustrating and explaining the present invention and is not intended to limit the present invention.
As shown in Figs. 1-2, a kind of novel flat-plate wheel includes mainly wheel 1, ratchet 2, pawl 3, connecting rod 4, elastic spiral shell
Mother 5 is fixedly mounted ratchet 2 in 1 side of wheel, and is rotated together with wheel 1, and ratchet 2 radius ratio wheel, 1 radius is small；It is carrying
When ratchet will not contact ground, it is ensured that its is stable.Connecting rod 4 is connected between wheel 1 and car body, connecting rod 4 passes through spiral shell
Silk installation on the car body, two pawls that can be rotated 3,3 tie point of pawl is equipped in connecting rod 4 by tightening nut 5
It is movable；Connecting rod 4 is designed using curved bar, ensures that pawl 3 has good angle that can block ratchet.Tightening nut 5 is used
In connection pawl 3 and connecting rod 4, side protrudes, so that pawl-and-gearing is in same plane, ensure that it can be worked normally.Spine
Wheel is equipped with adjusting elasticity part.Use adjustable-tightness part simultaneously, specific effect is 1. to unclamp elastic spiral shell when needing using ratchet
Mother, automatic dead-locking function open (since gravity pawl can be contacted with ratchet).2. ratchet need not be used, by spine
Pawl detaches with ratchet and screws on tightening nut upwards, and away from ratchet range, (pawl and ratchet are simultaneously for automatic dead-locking function closing
It is not in contact with).
Ratchet 2, pawl 3, connecting rod 4, tightening nut 5 use Fine Steel Casting iron structure, on the one hand ensure lighter in weight, separately
On the one hand ensure that performance is firm.
As shown in Fig. 2, the utility model size：R=150mm, r=120mm, l=60mm, L=120mm, α=60 °.
When starting ratchet, when wheel is run according to traffic direction as shown in the figure, ratchet can jack up pawl, to realize
Normal rotation.Once reverse direction operation occurs in vehicle, pawl can be automatically stuck by ratchet, to fixing vehicle wheel.1, by ratchet with
Wheel is combined, and ensures that wheel can one-directionally rotate.2, it is designed using pawl+tightening nut, can according to circumstances select to open
Or pawl is closed, it ensure that trolley flexibility.
It the foregoing is merely embodiments of the present invention are illustrated, is not intended to restrict the invention, for the technology of this field
For personnel, all within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in
Within protection scope of the present invention.
