Description
Technical field
The utility model is related to lifter technical field more particularly to a kind of reels for lifter.
Background technology
In trip's fire-fighting domain, often to use lifter cooperation rope, to reach make people or object rise to eminence or
Person drops to the case where lower.The coiling race of the lifter uses V-groove, and muscle outstanding is equipped on the two side of race
Item prevents from skidding.Shortcoming is that skid resistance is poor, is susceptible to skidding.
Invention content
The utility model aim is to solve the above problems and propose a kind of reel for lifter.
It is achieved through the following technical solutions above-mentioned purpose：
The utility model provides a kind of reel for lifter, including wheel body, and the race of the wheel body is that V-type is recessed
Slot, the V-type groove include left cell wall and right cell wall, several are distributed with around wheel body axial direction circumference array in the left cell wall
Several the first protrusions are distributed with around wheel body axial direction circumference array in first straight slot, the right cell wall, it is described several first
The center line with several first protrusions is on same straight line respectively for the center line of straight slot, and the left cell wall is around wheel body axis
There are several the second protrusions, the right cell wall to be distributed with around wheel body axial direction circumference array several to direction circumference array distribution
A second straight slot, the center lines of several second protrusions respectively the center line with several second straight slots in same
On straight line, the first straight slot trough rim is arc-shaped, and the second straight slot trough rim is arc-shaped.
Further, several semicircles are distributed with around wheel body axial direction circumference array in the race slot bottom of the wheel body
Slot.
Further, the semi-circular groove trough rim is arc-shaped.
The utility model has the beneficial effects that：When rope skids, it is necessary to overcome to rope and left cell wall and the right side
Radial frictional force caused by the axial compression of cell wall will also overcome to rope and be embedded in the part of the first straight slot or the second straight slot
With the first straight slot cell wall or the second straight slot cell wall squeeze caused by axial friction, the first straight slot trough rim be it is arc-shaped, second
Straight slot trough rim is arc-shaped, and to make the contact of the first straight slot trough rim and the second straight slot trough rim with rope be contacted for face, increase connects
Contacting surface is accumulated, while being avoided stress concentration and being damaged rope, and therefore, compared with prior art, the utility model reel is prevented
Skidding ability is stronger.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model.
Specific implementation mode
The utility model is described in further detail with specific implementation mode below in conjunction with attached drawing：
As shown in Figure 1, a kind of reel for lifter, including wheel body, the race of the wheel body is V-type groove, institute
It includes left cell wall 1 and right cell wall 2 to state V-type groove, the left cell wall 1 around wheel body axial direction circumference array be distributed with several
Several the first protrusions 21 are distributed with around wheel body axial direction circumference array in one straight slot 11, the right cell wall 2, it is described several
The center line with several first protrusions 21 is on same straight line respectively for the center line of one straight slot 11, the left cell wall 1
Several the second protrusions 12 are distributed with around wheel body axial direction circumference array, the right cell wall 2 is around wheel body axial direction Circle-Array
Column distribution has several the second straight slots 22, the center lines of several second protrusions 12 respectively with several described second straight slots
22 center line is on same straight line, and 11 trough rim of the first straight slot is arc-shaped, and 22 trough rim of the second straight slot is circular arc
Shape.
First protrusion 21 is welded with the right cell wall 2, and second protrusion 12 is welded with the left cell wall 1.
Several semi-circular grooves 13 are distributed with around wheel body axial direction circumference array in the race slot bottom of the wheel body 1.Work as rope
When rope bears overweight object, the race slot bottom of rope toward wheel body pushes, and rope por-tion is embedded into semi-circular groove, at this point, rope
It asks for when skidding, it is necessary to overcome circumferential frictional force caused by the extruding of the race slot bottom to rope and wheel body, also want
The part for overcoming to rope to be embedded into semi-circular groove squeezes generated radial frictional force with rope, to improve anti-skidding energy
Power.
13 trough rim of the semi-circular groove is arc-shaped.To make contact of the semi-circular groove trough rim with rope be contacted for face, increase
Large access area, while avoiding stress concentration and rope is damaged.
The above is not limit the technical scope of the present invention, all according to the utility model technical spirit
To any modification, equivalent variations and modification made by above embodiment, the model of the technical solution of the utility model is still fallen within
In enclosing.
Claims (3)
1. the race of a kind of reel for lifter, including wheel body, the wheel body is V-type groove, the V-type groove includes
