Preferably, described positioning seat can be arranged in the described support vertical rod up or down.
Further preferably, described support vertical rod comprises screw rod, described positioning seat comprises matching with described screw rod and merges mutually also two tight nuts, described spring housing is located on the described screw rod, also be arranged with upper padding plate and lower bolster on the described screw rod, the upper end of described spring pushes against described upper padding plate on described nut, and the bottom of described spring pushes against described lower bolster on described rope sheave mount pad.
Preferably, described rope sheave mount pad comprises the bottom, from upwardly extending both sides, the both sides of described bottom, the turn-up portion of extending laterally from the top of described both sides, form the installing space that holds rope sheave in the described rope sheave assembly between described bottom, the described both sides, the wheel shaft of described rope sheave assembly is installed on the described both sides, all offer perforation on the described turn-up portion, can slide up and down to be set in the described support vertical rod by the described rope sheave mount pad of the perforation on the described turn-up portion.
Because the utilization of technique scheme, the utility model compared with prior art has following advantage: when arranging tightening device, can set the position of pit upper support vertical rod according to the position of elevator speed limiter wire rope flexibly, supporting installation rope sheave mount pad, positioning seat, spring in the vertical rod then, make that the tightening device occupation space is little, compact conformation need not to consider the position of guide rail, this elevator over-speed governor tensioning apparatus flexible arrangement, convenience.When steel rope takes place to extend, the rope sheave assembly slides downwards, realize the tensioning of steel rope, the rope sheave assembly be to give with the downward elastic-restoring force of rope sheave mount pad by spring to realize to lower slider, adopt spring to replace the purpose that pouring weight reaches the tensioning steel rope, can reduce production costs like this.
Description of drawings
Accompanying drawing 1 is the scheme drawing of existing elevator over-speed governor tensioning apparatus;
Accompanying drawing 2 is looked scheme drawing for master of the present utility model;
Accompanying drawing 3 is a schematic side view of the present utility model, and speed limiter wire rope is walked around rope sheave downwards.
The specific embodiment
Further set forth structure of the present utility model below in conjunction with accompanying drawing.
Shown in Fig. 2-3, a kind of elevator over-speed governor tensioning apparatus comprises support vertical rod 1 that two couple on the pit 14 that is arranged on elevator is provided with separately, can slide up and down to be arranged on two pairs of rope sheave mount pad 6, wheel axle horizontals between the support vertical rod 1 that is provided with separately and be installed in rope sheave assembly 13 on the rope sheave mount pad 6, be arranged on the positioning seat 2 that supports in the vertical rod 1, be provided with between positioning seat 2 and rope sheave mount pad 6 and be in deformed state so that the spring 5 of the downward elastic-restoring force of rope sheave mount pad 6 to be provided.Support vertical rod 1 by being provided with on pit 14, rope sheave mount pad 6 slides up and down along supporting vertical rod 1, thereby is being with rope sheave assembly 13 to slide up and down.Steel rope 9 is walked around the rope sheave in the rope sheave assembly 13 downwards, when steel rope 9 takes place to extend, rope sheave assembly 13 is to lower slider, realize the tensioning of steel rope, rope sheave assembly 13 be to give with the downward elastic-restoring force of rope sheave mount pad 6 by spring 5 to realize to lower slider, adopt spring to replace the purpose that pouring weight reaches the tensioning steel rope, can reduce production costs like this, when arranging tightening device, can set the position of pit upper support vertical rod according to the position of elevator speed limiter wire rope flexibly, supporting installation rope sheave mount pad in the vertical rod then, positioning seat, spring, make that the tightening device occupation space is little, compact conformation need not to consider the position of guide rail, then this elevator over-speed governor tensioning apparatus flexible arrangement, convenient.
To elaborate the concrete enforcement structure of tightening device below, shown in Fig. 2 and 3, support the bottom bar 15 that vertical rod 1 comprises screw rod 3, is used for studdle 3, bottom bar 15 directly is fixed on the pit 14, positioning seat 2 comprises matching with screw rod 3 and merges mutually also two tight nuts 4, two nuts 4 are also tight mutually, can be locking.Spring 5 is set on the screw rod 3, also is arranged with upper padding plate 8 and lower bolster 7 on the screw rod 3, and the upper end of spring 5 pushes against upper padding plate 8 below nut 4, and the bottom of spring 5 pushes against lower bolster 7 on rope sheave mount pad 6.Spring the upper end can also fix with respect to upper padding plate 8 or nut 4, same, the bottom of spring 5 also can be fixed with respect to lower bolster 7 or rope sheave mount pad 6.In Fig. 2 and Fig. 3, the upper end of spring 5 pushes against upper padding plate 8 below nut 4, spring 5 itself is in deformed state, the bottom of spring 5 can be given and 6 one downward elastic-restoring forces of rope sheave mount pad like this, downward slip rope sheave mount pad 6, thereby the steel rope in can tension sheave assembly 13.
Rope sheave mount pad 6 comprises bottom 10,10 upwardly extending both sides 11, both sides, the turn-up portion 12 that extends laterally at 11 top from both sides from the bottom, form the installing space 16 that holds rope sheave in the rope sheave assembly 13 between bottom 10, the both sides 11, the wheel shaft of rope sheave assembly 13 is installed on the both sides 11, all offer perforation on the turn-up portion 12, can slide up and down to be set on the screw rod 3 that supports vertical rod 1 by the perforation rope sheave mount pad 6 on the turn-up portion 12, the bottom of spring 5 pushes against lower bolster 7 on turn-up portion 12.
By the screw thread fit of nut 4 with screw rod 3, can realize that positioning seat 2 is arranged in the support vertical rod 1 up or down, in Fig. 2 and 3, if downward turn nut 4, spring 5 is pressed tightly more like this, and the elastic-restoring force that imposes on rope sheave mount pad 6 is big more, and the effect of tensioning steel rope is better, generally select for use the number of turns more, elastic-restoring force comparison pulsation-free spring uses.
