Description
Technical field：
Oil field of electromechanical technology is the utility model is related to, more particularly to a kind of top drive guide rail connecting pins.
Background technology：
Connected between top drive guide rail section and section using axis pin, to fix two section guide rails and pin is will not fall off in itself,
Among middle whole axis pin for being provided with annular groove is penetrated four pin holes of the matched both ends guide rail head of two section guide rails, then use
A piece positioning pin pins annular groove and achieves the goal.But due to being subject to two shearing forces of the two groups of pin holes in both sides, cause
Axis pin centre position is vulnerable to Moment repeatedly, and especially middle part is also provided with the recessed grain of annular, thus often cause axis pin from
The situation of centre fracture, can cause axis pin to deviate from, guide rail drops, and jeopardizes construction personnel's life security when serious.
Utility model content：
The technical problem to be solved by the present invention is to provide one kind to push up drive guide rail connecting pins, and the arrangement achieves logical
Cross and guide rail pin is divided into two sections, it is carried left and right sides guide rail head pin hole respectively and coordinate the shearing force produced, may be not present
Middle part produces the problem of moment of flexure, reduces pin fracture, slips and cause guide rail to drop the possibility to cause casualties.Gram
The existing guide rail pin deficiency that easily there is a situation where be broken between therefrom is taken.
Technical solution adopted in the utility model is：One kind top drive guide rail connecting pins, including axis pin I and axis pin
Ⅱ；Annular groove is provided with axis pin I and pin shaft II one end outer wall, guide rail pin positioner one end symmetric design there are two to determine
Position groove, axis pin I and pin shaft II are symmetrically mounted on guide rail head, and the annular groove on axis pin I and pin shaft II can be respectively with leading
Two positioning grooves on rail pin positioner coordinate positioning, and connection locating part is U-shaped, and connection locating part both ends are welded on
On guide rail head, it is spacing and can be slided between connection locating part both ends that guide rail pin positioner is connected locating part.
Axis pin I and the half that pin shaft II length is top drive guide rail width.
The section of guide rail pin positioner is U-shaped shape, and guide rail pin positioner side is strengthened connecting by connecting rod.
The beneficial effects of the utility model are：The utility model is realized by the way that guide rail pin is divided into two sections, makes its point
Not Cheng Zai left and right sides guide rail head pin hole coordinate the shearing force produced, the problem of middle part produces moment of flexure may be not present, reduce
Pin fracture, slip and cause guide rail to drop the possibility that causes casualties.

Embodiment：
As shown in Figure 1, Figure 2, Figure 3, Figure 4, a kind of top drive guide rail connecting pins, including axis pin I 1 and pin shaft II 2；Axis pin
I 1 and 2 one end outer wall of pin shaft II on be provided with annular groove, 3 one end symmetric design of guide rail pin positioner has two positioning recessed
Groove, axis pin I 1 and pin shaft II 2 are symmetrically mounted on guide rail head 6, and the annular groove on axis pin I 1 and pin shaft II 2 can be respectively with leading
Two positioning grooves on rail pin positioner 3 coordinate positioning, connect locating part 4 as U-shaped, the weldering of 4 both ends of connection locating part
It is connected on guide rail head 6, guide rail pin positioner 3 is connected that locating part 4 is spacing, and guide rail pin positioner 3 can connect
Slided between 4 both ends of locating part to reach the locked axis pin I 1 of positioning and pin shaft II 2 and unlock the two of axis pin I 1 and pin shaft II 2
Kind state.
Axis pin I 1 and the half that 2 length of pin shaft II is top drive guide rail width.
The section of guide rail pin positioner 3 is U-shaped shape, and 3 side of guide rail pin positioner is strengthened connecting by connecting rod 5
Connect.
It is understood that above with respect to the specific descriptions of the utility model, it is merely to illustrate the utility model and is not
The described technical solution of the utility model embodiment is limited to, it will be understood by those of ordinary skill in the art that, still can be with
Modify to the utility model or equivalent substitution, to reach identical technique effect；As long as satisfaction uses needs, all in this reality
Within new protection domain.
