Description
Technical field
The utility model belongs to lift product technical field, in particular to a kind of Weight type elevator over-speed governor tensioning apparatus.
Background technique
In the prior art, the wirerope of elevator governor is universal simultaneously wound on governor sheave and tensioning wheel, in closing
Ring status, the weight and tensioning wheel for being tensioned wirerope are connected to guide rail by mounting bracket or are fixed on pit ground.In electricity
When ladder operation.Weight is to maintain relative static conditions.The over-speed governor tensioning apparatus of this structure occupies pit space, and the speed limit
The installation of device tensioning apparatus is limited by guide rail arrangement and pit hedging space, it is difficult to is applied to shallow pit hoistway, be influenced elevator
Hoisting depth.
Therefore, research and develop it is a kind of can effectively save pit space, structure is simple, be suitable for shallow pit, low hoisting depth elevator
Weight type elevator over-speed governor tensioning apparatus it is extremely urgent.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, specifically disclose a kind of Weight type elevator governor tensioning
Device, the Weight type elevator over-speed governor tensioning apparatus, is effectively saved pit space, it is ensured that the hoisting depth of elevator, it can be extensively
Suitable for the low hoisting depth elevator of shallow pit, furthermore its structure is simple, reduces cost of manufacture.
In order to reach above-mentioned technical purpose, the utility model is realized by following technical scheme:
A kind of Weight type elevator over-speed governor tensioning apparatus described in the utility model, including mounting seat and limiter of speed master
Body, the wirerope one end of coiling passes sequentially through steel wire rope head, connection component and safety tongs on the rope sheave of the limiter of speed main body
Plate connection is lifted, the other end of the wirerope of coiling is hung by bolt and nut component on the rope sheave of the limiter of speed main body
It is connected with weight, the elevator shaft wall of the weight corresponding position is equipped with accommodating weight and for weight operation up and down inside it
Hollow sleeve, the bottom of the hollow sleeve adjacent to the bottom of elevator pit, and the bottom position of hollow sleeve correspondence set
There are protective device and breaking rope protecting switch.
As the further improvement of above-mentioned technology, the bolt and nut component includes the bolt sleeve being fixedly connected and locking
Nut, the weight are connected to the terminal part of wirerope by bolt sleeve and are locked by locking nut.
As the further improvement of above-mentioned technology, the protective device is protection baffle, is fixedly mounted on elevator
On road wall.
In the present invention, the breaking rope protecting switch is placed in the bottom surface of elevator shaft, and its top is mounted on protection
The bottom position of baffle.
Compared with prior art, the utility model has the beneficial effects that
(1) Weight type elevator over-speed governor tensioning apparatus described in the utility model holds due to being equipped on elevator shaft wall
The hollow sleeve setting weight and running up and down inside it for weight, weight are vacantly arranged in hollow sleeve, and weight is hanging down
It is the operation above and below the safety of carriage reverse direction operation in straight catheter, weight is not needed to connect with guide rail or ground, be greatlyd save
Pit space, structure is simple, the low hoisting depth elevator suitable for shallow pit；
(2) this practical described Weight type elevator over-speed governor tensioning apparatus makes elevator by reasonably selecting the weight of weight
The tensile force of wirerope is less than lifting power required when safety tongs acts when normal operation, preferably ensures that safety tongs will not malfunction
Make, effectively increase security performance when elevator operation, reliability greatly improves.
Detailed description of the invention
The utility model is described in detail in the following with reference to the drawings and specific embodiments:
Fig. 1 is Weight type elevator over-speed governor tensioning apparatus structural schematic diagram described in the utility model.
Specific embodiment
As shown in Figure 1, a kind of Weight type elevator over-speed governor tensioning apparatus described in the utility model, including mounting seat 1
With limiter of speed main body 2, on the rope sheave 21 of the limiter of speed main body 23 one end of wirerope of coiling pass sequentially through steel wire rope head 4,
Connection component 5 is connect with safety tongs lifting plate 6, the other end of the wirerope 3 of coiling on the rope sheave 21 of the limiter of speed main body 2
It is connected with weight 7 by what bolt and nut component 10 was hung, the elevator shaft wall 20 of 7 corresponding position of weight is equipped with accommodating
Weight 7 and the hollow sleeve 8 run up and down inside it for weight 7, the bottom of the hollow sleeve 8 is adjacent to the bottom of elevator pit
Portion, and protective device 9 and breaking rope protecting switch 30 are correspondingly provided in the bottom position of hollow sleeve 8.
As shown in Figure 1, the bolt and nut component 10 includes the bolt sleeve 11 and locking nut 12 being fixedly connected, described
Weight 7 is connected to the terminal part of wirerope 3 by bolt sleeve 11, and is locked by locking nut 12.
In the present invention, the protective device 9 is protection baffle, is fixedly mounted on elevator shaft wall 20, institute
The bottom for stating breaking rope protecting switch 10 is placed on the ground of elevator pit, and its top is mounted on the bottom position of protection baffle.
Weight type elevator over-speed governor tensioning apparatus described in the utility model, the tensioning of wirerope 3 be by weight 7 from
It re-opens tightly, in use, the tensile force of wirerope 3 is less than safety when operating normally elevator by the weight for reasonably selecting weight 7
Pincers lifting power required when acting, can effectively ensure that safety tongs will not malfunction.
When wirerope 3 disconnects or weight 7 falls into the extreme case generation of elevator shaft, protection baffle can be in steel wire
Weight 7 can be blocked in time when 7 freely falling body of weight after rope 3 disconnects, and triggers breaking rope protecting switch 30 at once, stop elevator
Operation, it is ensured that elevator safety service performance.
