Abstract

The utility model relates to a clamping self-locking rope clip used for mine etc., in particular to a one-way self-locking rope clip. Two side plates are connected through a pin shaft; one side of the two side plates hold a wedge back in between; a bolt penetrates through anotherside of the side plate to fix and connect the side plate; the inclined surfaces of the two wedge blocks correspond to the inclined surface of the wedge back, which are enclosed in an inclined space formed between 4 side plates and 2 wedge backs; a plane rolling bearing is arranged between the inclined planes of the wedge block and the wedge back. Using the above proposal makes the structure of the rope clip simple, working reliable and safe; the utility model can quickly block the rope, and is characterized in one-way self-locking, rapid reverse release and flexible assembly and disassembly.

Description

The unidirectional self-lock wire clips

Affiliated technical field

The utility model relates to the clamping self-locking wire clips of the wire rope that mine etc. locates to use, especially a kind of unidirectional self-lock wire clips.

Background technique

Present known card deragger, safeguarding, overhauling, all needing an end or the other end on the wire rope are fixed when changing, the general at present clamping plate bolt and hanger in place that adopt, this method dismounting, installation, very loaded down with trivial details, labor intensity and workload are very big, and the dangerous accidents such as pit shaft that drop such as clamping plate or bolt take place easily.

Summary of the invention

In order to overcome some shortcomings of existing wire line shoe, the utility model provides a kind of unidirectional self-lock wire clips, and this wire clips is simple in structure, reliable operation, can be blocked wire rope fast at safety, and has unidirectional self-lock, the reverse characteristics of freeing fast, dismounting is very convenient.

The technological scheme that its technical problem that solves the utility model adopts is: this self-locking wire clips comprises voussoir, plane rolling bearing, the wedge back of the body, side plate, bearing pin, handle and several major parts of bolt, voussoir (2) is a rectangular-shaped wedge body, and there is straight-through together curve bath (2-1) its side; Side plate (8) is an independently rectangular plate, its side has several protruding boss, groove between this boss is corresponding with the boss of another side plate to coincide, pin shaft hole passes from top to bottom, make between the boss and communicate, making two side plates (8) carry out glue by bearing pin connects, a wedge back of the body of clamping (4) between one side of two side plates (8), bolt is passed by the another side of side plate (8), and is fixedly connected it, makes between the wedge back of the body and forms a space that has gradient, the wedge back of the body (4) is the square cylinder that one one side has the inclined-plane, its height equates that with side plate (8) its bevel angle is identical with the bevel angle of voussoir (2), but direction is opposite; The inclined-plane of the inclined-plane of two voussoirs and the wedge back of the body (4) is corresponding, between pack into 4 side plates and 2 the wedges back ofs the body that can be slidingly matched in the space that has gradient of formation; Between the inclined-plane of the voussoir (2) and the wedge back of the body (4), the plane rolling bearing is housed, the plane rolling bearing is by the circular hole of rectangle retainer side, roller is fixedly connected into an integral body, make the plane rolling bearing easily integral body take out and put into, be unlikely to make roller to be scattered.

Its beneficial effect is: owing to adopted such scheme, make this wire clips simple in structure, reliable operation, can be blocked wire rope fast at safety, and has unidirectional self-lock, reverse characteristics of freeing fast, and dismounting is very convenient flexibly.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples:

Accompanying drawing 1 is a structural principle schematic representation of the present utility model;

Accompanying drawing 2 is a structural principle plan view of the present utility model.

Among the figure, 1 wire rope, 2 voussoirs, the 2-1 curve bath, 3 handgrips, the 4 wedges back ofs the body, 5 plane rolling bearings, 6 bolts, 7 bearing pins, 8 side plates, 9 take away the position view of opening wire clips behind the bearing pin.

Embodiment

In the drawings, after side plate (8) is fixed by bolt (6) with the wedge back of the body (4), two pairs of side plates (8) are corresponding to coincide, pass pin shaft hole by bearing pin (7) and carry out the glue connection, a pair of voussoir (2) is packed in the space, inclined-plane between side plate (8) and the wedge back of the body (4), voussoir (2) and wedge are carried on the back the plane rolling bearing (5) of packing between (4), such structure is integral body of the present utility model, take away the bearing pin (7) between the side plate (8), can open this wire clips, the wire rope (1) of can packing into easily makes wire rope (1) be adjacent to curve bath (2-1) and contacts, because the effect of wire rope (1) load, promptly drive voussoir (2) along the inclined-plane of the wedge back of the body (4) to bottom offset, because voussoir Yu moves down, the gap between the voussoir curve bath (2-1) is more little, thereby can block wire rope tightly, when jammed wire rope (1) reverse when stressed, wire rope (1) drives voussoir (2) reversing motion, and the gap between the voussoir curve bath (2-1) is strengthened, and wire rope (1) is thrown off easily.

Claims

1, a kind of unidirectional self-lock wire clips is characterized in that: two side plates (8) carry out glue by bearing pin (7) and connect, a wedge back of the body of clamping (4) between the side of two side plates (8), and bolt is passed by the another side of side plate (8), and is fixedly connected it; The inclined-plane of the inclined-plane of two voussoirs (2) and the wedge back of the body (4) is corresponding, between pack into 4 side plates and 2 the wedges back ofs the body that are slidingly matched in the space that has gradient of formation; Between the inclined-plane of the voussoir (2) and the wedge back of the body (4), the plane rolling bearing is housed.

2, unidirectional self-lock wire clips according to claim 1 is characterized in that: voussoir (2) is a rectangular-shaped wedge body, and there is straight-through together curve bath (2-1) its side.

3, unidirectional self-lock wire clips according to claim 1, it is characterized in that: side plate (8) is an independently rectangular plate, its side has several protruding boss, groove between this boss is corresponding with the boss of another side plate to coincide, the boss of pin shaft hole below the top of boss led directly to makes between the boss to communicate.

4, unidirectional self-lock wire clips according to claim 1 is characterized in that: the wedge back of the body (4) is the square cylinder that one one side has the inclined-plane, and its height equates that with side plate (8) its bevel angle is identical with the bevel angle of voussoir (2), but direction is opposite.

5, unidirectional self-lock wire clips according to claim 1 is characterized in that: the plane rolling bearing is fixedly connected into an integral body to roller by the circular hole of rectangle retainer side.
