Description
Technical field
The utility model belongs to mine car accessory technical field of improvement, and in particular to a kind of mine car anticreep vertical pin.
Background technique
My mine has about more than 500, one ton of mine car, each mine car is equipped with 2 vertical pins, and such one ton of mine car vertical pin shares 1000
It is multiple.It not only to be assorted to each mine car according to regulation mine car vertical pin, also to there is the protection dress to fall off that prevents from voluntarily scurrying out upwards
It sets.It is to prevent mine car vertical pin from falling off before transformation, it is ensured that can be latched, be positioned against one section of width 10mm, depth of plane on vertical pin axis
The slot of 5mm, for the slot from being dug one end of vertical pin, length accounts for about the 90% of vertical pin length；The steel loop of a 10mm thickness is reprocessed,
Diameter of bore has more the diameter 2mm of vertical pin, a certain position of inner hole there are one it is trapezoidal it is convex stick up, the trapezoidal convex size and length sticked up
It is approximately less than the slot that vertical pin is dug.With this it is convex stick up be stuck in slot play the role of preventing lose.One is dug in vertical pin end circumferential direction
A slot, when use vertical pin rotate it is trapezoidal it is convex stick up into locking is played the role of in the slot of circumferential direction, here it is pins to be transformed
The transformation of the preceding method used and pin.In this way vertical pin have the defects that one it is fatal, be exactly easy or taken away by people, reason
It is that trapezoidal convex stick up is easily damaged.Mine car once loses vertical pin, and individual electric locomotive drivers follow the line of least resistance for convenience, just uses when in use
Other item in place vertical pins bring hidden danger to transporting safely in this way.
Existing coalcutter is generally that two height-regulating oil cylinder settings are being leaned below the fuselage of coal wall side, the piston rod and rocker arm of oil cylinder
Small support arm, cylinder body and left and right tractive unit use pin shaft joint separately below, to realize the height-regulating of left and right roller.It is living that oil cylinder is turned up
The pin shaft that stopper rod couples with rocker arm, the method for being utilized in external nose end mounting hole circlip prevent pin shaft from altering axis.But in underground
In use, will lead to hole card spring fracture failure, pin shaft axially loses about since the axial unexpected stress of vibratory impulse pin shaft is serious
Shu Jiyi scurries out, and seriously affects the safety in utilization of equipment.
Utility model content
Vertical pin existing mine car there are problems that causing the accident because circlip is broken in use, the utility model
A kind of mine car anticreep vertical pin with insurance function is provided.To overcome vertical pin relaxation to fall off, safety coefficient is improved.
Solution adopted by the utility model to solve its technical problems is that: a kind of mine car anticreep vertical pin, including shank, end cap
And circlip, it in the jump-ring slot for installing circlip, extends radially through and is provided with radial through-hole, successively suit is solid in radial through-hole
Determine back seat, spring and elastic dowel, wherein fixed back seat is fixed in the radial through-hole, fixed back seat is interior with elastic dowel
End, distribution are provided with spring fixed seat, and the both ends distribution of spring is fixed on corresponding spring fixed seat.
The axle center of the elasticity dowel is corresponding with the position at circlip inner surface center.
The diameter of the radial through-hole is greater than the thickness of circlip.
It is provided with planar section on the inside of the jump-ring slot, and the inner sidewall of circlip is provided with corresponding planar section, blocks
The planar section of spring is matched with the planar section of jump-ring slot and is set in together.
The beneficial aspects of the utility model: the utility model can be after there is rupture failure in circlip, and elastic dowel is outside
Pop-up is for preventing the shank of vertical pin from falling off, to protect using safe, equipment damage and people caused by preventing because of vertical pin abjection
Member is injured.
Since in such a way that spring is fixedly connected with elastic dowel, elastic dowel is by circlip compression in hidden under normal circumstances
Hiding state, elastic dowel also has after pop-up centainly to be caused to hinder and shake to vertical pin, to remind the new circlip of installation, is reached
Insurance prompt purpose.
Detailed description of the invention
Fig. 1 is the surface structure schematic diagram of the utility model.
Fig. 2 is A-A the schematic diagram of the section structure in Fig. 1.
Fig. 3 is the structural schematic diagram that Fig. 2 deletes circlip.
Fig. 4 is the B of Fig. 3 to structural schematic diagram.
Figure label: 1 is shank, and 2 be cap end, and 3 be circlip, and 4 be jump-ring slot, and 5 be radial through-hole, and 6 be to fix back seat, 7
It is spring for elastic dowel, 8,9 be spring fixed seat.
Specific embodiment
Embodiment 1: mine car anticreep vertical pin as shown in Figure 1, including shank, end cap and circlip.Wherein, shank end is arranged
There is the jump-ring slot of annular, for installing circlip.
As shown in Fig. 2, extending radially through in jump-ring slot and being provided with radial through-hole, and successively covered in radial through-hole
Fill fixed back seat, spring and elastic dowel.Wherein, fixed back seat is fixed in the radial through-hole, and fixed back seat and elasticity are dark
The inner end of pin, distribution are provided with spring fixed seat, and the both ends distribution of spring is fixed on corresponding spring fixed seat.Using spring
It is fixedly connected with the mode of elastic dowel, elastic dowel is in hidden state by circlip compression under normal circumstances, can go out in circlip
After existing rupture failure.As shown in figure 3, elastic dowel pops up the pin for preventing vertical pin outward after circlip occurs collapsing short failure
Body falls off, to protect using safe, equipment damage and injury to personnel caused by preventing because of vertical pin abjection.
As shown in figure 4, the axle center of elastic dowel is corresponding with the position at circlip inner surface center, and radial through-hole
Diameter is greater than the thickness of circlip.So that it is guaranteed that circlip can constrain elastic dowel securely, prevent elastic dowel in non-faulting shape
It is popped up under state.
Embodiment 2: on that basis of example 1, have and be provided with planar section on the inside of jump-ring slot, and in the inner sidewall of circlip
It is provided with corresponding planar section, the planar section of circlip is matched with the planar section of jump-ring slot and is set in together.So as to prevent card
Spring can be rotated arbitrarily in jump-ring slot, it is ensured that circlip is effective always to the constraint of elastic dowel.
By being as above transformed, the connection pin shaft of height-regulating oil cylinder and the small support arm of rocker arm, which alters axis phenomenon of the failure, thoroughly to be eradicated, really
The security reliability of its coupling arrangement is protected, has established solid foundation for the safe and highly efficient operation of complete machine.Damage is reduced after transformation
Bad number saves maintenance cost and extends the use time of a line production unit.Further decrease production cost.
