The present invention discloses a kind of safety guard of gig; it comprises gig, load cable and safety steel cable; described gig side is provided with permanent seat; conical cavity is provided with in the middle part of described permanent seat; pressure rope steel ball and trochoid spiral stage clip is disposed with from top to bottom in described conical cavity; described pressure rope steel ball is arranged on guide pillar, and described pressure rope steel ball is through guide pillar wall, and described guide pillar runs through permanent seat.When there is the disconnected rope of load cable, the swing arm of compression is unclamped, and its pressure rope steel ball is driven by trochoid spiral stage clip and the directional tagging of conical cavity, inwardly compresses and safety steel cable in locked guide pillar, and pressure steel ball clamping stroke of restricting is short, and brake response is sensitive; And owing to adopting conical cavity structure in permanent seat, make the tenesmus of pressing rope steel ball along with permanent seat, in conical cavity, thrust strengthens, and achieve the auto-lock function of pressure rope steel ball, braking effect is better, thus ensure that the safety of gig.

Description

The safety guard of gig
Technical field
The present invention relates to a kind of lift system, particularly relate to a kind of safety guard of gig.
Background technology
As everyone knows, the Main Function of gig material or equipment is sent to eminence from lower or is sent to lower from eminence, and it is simple that it has structure, installs, removes and the advantage such as easy to use.But in construction, operation, often cause grave accident because of the disconnected rope of traction steel rope of cable of gig, therefore when designing gig, all safety guard can be installed, prevent the generation of falling accident.Protecting equipments for elevating conveyor many employings Wedge-type rope broken protector common at present; its keystone configuration comprises a movable wedge and fixing voussoir; therebetween can relative sliding along inclined-plane; when there is disconnected rope in steel cable; by compressing movable wedge side; make the opposite side of movable wedge tilt and fix voussoir to compress, and fastening safety steel cable between the two, thus ensure that gig can not fall because of disconnected rope.But this fender guard structure is too complicated; compress movable wedge and need larger power, can not instantaneously reach, and the easy bad student's corrosion of relative sliding between two voussoirs; thus reducing the action sensitivity of fender guard, fall arrest distance easily exceedes the scope of national regulation.
Summary of the invention
The object of the present invention is to provide a kind of safety guard of gig, its braking is sensitive, and the reaction time is short, and good braking effect, drop apart from short, safety is high.
The object of the invention is to be achieved through the following technical solutions:
A kind of safety guard of gig, comprise gig, load cable and safety steel cable, described gig side is provided with permanent seat, conical cavity is provided with in the middle part of described permanent seat, pressure rope steel ball and trochoid spiral stage clip is disposed with from top to bottom in described conical cavity, baffle ring and hole locking plate are installed bottom described conical cavity, described pressure rope steel ball is arranged on guide pillar, and described pressure rope steel ball is through guide pillar wall, described guide pillar runs through permanent seat, described guide pillar top is provided with annulus seat board, described gig top is hinged with jib, described jib inside is provided with the roll sleeve and roller that cooperatively interact, described jib side is provided with swing arm, described swing arm end is provided with fore-set, described fore-set is placed on annulus seat board, described load cable is through gig and be placed on roll sleeve and roller, described safety steel cable is placed in guide pillar.
Described permanent seat is fixed on L shape adapter plate, and described L shape adapter plate transverse plate is provided with conductor rope cover, and described L shape adapter plate is bolted on gig, and described safety steel cable is through conductor rope cover.
Beneficial effect of the present invention is, the safety guard of described gig, when the disconnected rope of generation load cable, its pressure rope steel ball passes through the directional tagging of the drive of trochoid spiral stage clip and conical cavity, inside compression safety steel cable in locked guide pillar, pressure rope steel ball clamping stroke is short, and brake response is sensitive; And owing to adopting conical cavity structure in permanent seat, make the tenesmus of pressing rope steel ball along with permanent seat, in conical cavity, thrust strengthens, and achieve the auto-lock function of pressure rope steel ball, braking effect is better, thus ensure that the safety of gig.

Detailed description of the invention
As shown in Figure 1, in the present embodiment, the safety guard of described gig, comprise gig 1, load cable 2 and safety steel cable 3, gig 1 side is provided with permanent seat 4, top is hinged with jib 12, jib 12 side is provided with swing arm 15, described swing arm 15 end is provided with fore-set 16, described fore-set 16 is placed on annulus seat board 11, load cable 2 is through gig 1 and jib 12, safety steel cable 3 is fixed in guide pillar 10, permanent seat 4 is fixed on L shape adapter plate 17, L shape adapter plate 17 is fixed on gig 1 by bolt 19, L shape adapter plate 17 transverse plate is provided with conductor rope cover 18.
As shown in Figures 2 and 3, conical cavity 5 is provided with in the middle part of permanent seat 4, pressure rope steel ball 6 and trochoid spiral stage clip 7 is disposed with from top to bottom in conical cavity 5, be provided with baffle ring 8 and hole locking plate 9 bottom conical cavity 5, pressure rope steel ball 6 is arranged on guide pillar 10, and described pressure rope steel ball 6 is through guide pillar wall, and the pressure rope steel ball 6 be arranged on guide pillar 10 is preferably 3, also can be multiple, guide pillar 10 runs through permanent seat 4, and guide pillar 10 top is provided with annulus seat board 11.
As shown in Figures 4 and 5, jib 12 side is provided with swing arm 15, and swing arm 15 end is provided with fore-set 16, and jib 12 inside is provided with the roll sleeve 13 and roller 14 that cooperatively interact.
During normal work, load cable 2 is through gig 1 and the roll sleeve 13 be placed in jib 12 and roller 14, during due to hoisting heavy, load cable 2 is stressed to be tightened, simultaneously load cable 2 applies transversely by pressure from tension force to jib 12, make the swing arm 15 on jib 12 and gig 1 keeping parallelism state, thus the fore-set 16 of swing arm 15 end holds out against and presses down annulus seat board 11, annulus seat board 11 drives guide pillar 10 downward, and compress trochoid spiral stage clip 7, pressure rope steel ball 6 moves downward with trochoid spiral stage clip 7, now be in released state, make safety steel cable 3 can overlap 18 and guide pillar 10 by conductor rope smoothly, ensure the normal operation of gig.
Off working state or when there is disconnected rope, load cable 2 does not stress, simultaneously load cable 2 applies transversely by distress resolves from tension force to jib 12, the fore-set 16 of swing arm 15 end is made not overcome the elastic force of trochoid spiral stage clip 7 and be lifted, now, under the elastic force effect of trochoid spiral stage clip 7, pressure rope steel ball 6 and guide pillar 10 upward movement, and pressure rope steel ball 6 is by the directional tagging of the conical cavity 5 in permanent seat 4, tighten up to centre gradually, and draw close until lock to the safety steel cable 3 in guide pillar, after safety steel cable 3 is locked, owing to adopting conical cavity 5 in permanent seat 4, make the tenesmus of pressing rope steel ball 6 along with permanent seat 4, in conical cavity 5, thrust strengthens, achieve the auto-lock function of pressure rope steel ball 6, now gig 1 is locked on safety steel cable 3 by permanent seat 4, ensure that the safety of equipment and personnel.
Its braking of the safety guard of described gig is sensitive, and the reaction time is short, and good braking effect, drop apart from short, safety is high.
