Description
Technical field
The utility model relates to forklift structures to be related to field, the in particular to design of forklift lift valve.
Background technique
Manual forklift can complete the work of lifting stacking without additionaling power, together as unpowered industrial truck
When pollution with not noise and flexibly the advantage that moves, manual forklift have a wide range of applications in factory.
The design that some details are had ignored in existing forklift design, in lift valve design, due in fastening bolt
Portion does not have fixing end, does not have to be connected with cut-off ball yet, may result in fastening bolt and gone out by lemon unintentionally, draining occurs；Bolt
Random place the loss that may also cause bolt.Since cut-off ball is no and bolt is fixed, it is also possible to cause cut-off ball
Loss so that forklift hydraulic system needs to dismantle maintenance again.
For rotating handles due to being commonly used, surface is prone to wear and receives the corrosion of oil when draining, influences work experience.
Utility model content
The technical problem to be solved by the utility model is to overcome the deficiencies of existing technologies, propose that a kind of modified heap is high
Vehicle lift valve improves lift valve internal structure and rotating handles, so that work is more reliable and more stable, uses and more relaxes
It is suitable.
The technical solution of the utility model includes:
A kind of modified is used for the lift valve of forklift comprising, inner casing, outer shell ends ball, goes up and down valve shaft, fastens spiral shell
Bolt and rotating handles.Lifting valve shaft is nested in outer shell cinclides, and fastening bolt is nested in lifting valve shaft, in leaning on for fastening bolt
There is a cut-off ball in interior casing wall one end, there is a drain tap on interior casing wall, and shape matches with cut-off ball, and position is located at cut-off
Ball stroke accessible position has a rotating handles in outer casing wall one end of fastening bolt.
Further, pretightning force is promoted when going up and down valve shaft and outer casing wall is practical is screwed, and installing.
Further, it goes up and down valve shaft and fastening bolt to be threadedly coupled using sealing, contact surface is coated with lubricating oil.
Further, fastening bolt is equipped with baffle arrangement close to interior casing wall one end.
Further, cut-off bulb diameter is greater than oil cylinder spacing, greater than the diameter of fastening bolt, is less than empty inside lifting valve shaft
Between diameter.
Further, rotating handles use corrosion-resistant plastic material.
Further, rotating handles are fixed by card slot and fastening bolt.
Further, anti-skidding groove is carved on rotating handles surface.
Further, the drain tap on interior casing wall and cut-off ball surface are coated with wearing layer.
The utility model has the following beneficial effects: follow-on structure makes fastening bolt not gone out fall off by lemon, end ball
It will not cause to lose.The fixed lifting valve shaft of the mode of threaded connection is easy to disassemble and replaces.Follow-on rotating handles are convenient for
It assembles and durable.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawing:
Fig. 1 is the utility model throttle-valve structure schematic diagram；
Fig. 2 is the schematic diagram of the utility model throttle valve rotating handles.
Specific embodiment
Specific embodiment of the present utility model is described in detail with reference to the accompanying drawing.
As shown in Figure 1, the utility model devises a kind of forklift lift valve.It includes inner casing, outer shell, ends ball 6,
Go up and down valve shaft 3, fastening bolt 5 and rotating handles 4.Lifting valve shaft 3 is nested in outer 2 hole of casing wall, and fastening bolt 5 is nested in lifting
In valve shaft 3, there is a cut-off ball 6 in 1 one end of inner casing wall of fastening bolt 5, have a drain tap 7, shape on interior casing wall 1
It matches with cut-off ball 6, position is located at cut-off 6 stroke accessible position of ball, has in 2 one end of outer casing wall of fastening bolt 5
One rotating handles 4.
When forklift works, fastening bolt 5 is tightened, and cut-off ball 6 is bonded the drain tap 7 on interior casing wall, so that interior casing wall seals
It closes.Hydraulic oil injects high pressure oil area 8, and pressure constantly rises, so that forklift rising height.When forklift unloads, fastening bolt 5
Unscrew, high pressure oil area 8 is connected to oil cylinder 9, and hydraulic oil flows into oil cylinder 9, so that forklift is slowly fallen, completes uninstall action.
Lifting valve shaft 3 and outer casing wall 2 is practical is screwed, and while installing, promotes pretightning force.This structure makes lift valve
It is easily installed and dismantles, replacement is convenient, convenient for using in production.
It goes up and down valve shaft 3 and fastening bolt 5 to be threadedly coupled using sealing, contact surface is coated with lubricating oil, it is ensured that fastening bolt 5 can
Good leakproofness is kept while to move.Fastening bolt 5 has one section of thicker baffle arrangement close to interior casing wall one end, this
The thicker baffle arrangement of section makes the stroke of fastening bolt 5 suffer restraints, will not directly lemon go out, avoid fastening bolt 5 by lemon
The case where causing draining and fastening bolt 5 to leave about loss out.
End 6 diameter of ball and be greater than 9 spacing of oil cylinder, greater than the diameter of fastening bolt 5, it is straight to be less than lifting 3 inner space of valve shaft
Diameter moves cut-off ball 6 inside lifting valve shaft 3, but not slides to oil cylinder 9.
Rotating handles 4 use corrosion resistant plastic material, such as: polyvinyl chloride, polyamide；Rotating handles pass through card slot 10
It is fixed with fastening bolt 5；It is carved with anti-skidding groove 11 in 4 surface of rotating handles.It is such design so that rotating handles 4 are both corrosion-resistant can
It leans on, and can anti-skidding use well, the installation easy to disassemble of the fixed form of card slot 10 and replacement.
Drain tap 7 and cut-off 6 surface of ball on interior casing wall 1 are coated with wearing layer.Due to the surface of oil leak hole 7 and cut-off ball 6
Contact constitutes closed interior casing wall 1, and the abrasion prevention and treatment of oil leak hole 7 and cut-off ball 6 is most important, increases by one layer of chromium wearing layer,
Leakage caused by abrasion can be effectively avoided.
Basic principles, main features, and advantages of the present invention has been shown and described above.This reality
It is not restricted to the described embodiments with novel, the above embodiments and description only describe the originals of the utility model
Reason, the utility model also has various changes and improvements on the premise of not departing from the spirit and scope of the utility model, these changes
Change and improvement is both fallen in the range of claimed invention.The utility model requires protection scope is by appended right
Claim and its equivalent define.
