The roller replacing device comprises a support body which can be conveniently fixed on a roller rack, wherein one side of the support body is provided with an ejector mechanism, the ejector mechanism is internally provided with a ladder-shaped screw driving device which can move upward or downward vertical to the direction of the roller rack under the action of a matched ladder-shaped nut; the support body is formed by a support which is provided with a locating bolt used for fixing and a connecting rib plate used for connecting a guide sleeve in the ejector mechanism, the ladder-shaped screw is connected into the guide sleeve in a screwing manner, the ladder-shaped nut which is arranged above the guide sleeve and is matched with the ladder-shaped screw is provided with a bidirectional ratchet gear; and the ladder-shaped screw driving device comprises one ladder-shaped screw, the upper end of the ladder-shaped screw is provided with a T-shaped top plate which is connected by virtue of a pin roll and is contacted with a conveyed belt. The roller replacing device disclosed by the invention has the advantages of small volume, light weight, simple structure, convenience in application and carrying and safety and reliability in operation.
Description
Technical field
What the present invention relates to is a kind of carrying roller changing device more of ribbon conveyer, belongs to a kind of machinery overhaul electrician testing tool technology field.
Background technology
For enterprises such as picture large-size thermal power plants, it is an essential and very hard work that conveyer belt damages the carrying roller replacing.Usually the method changed of carrying roller is to creep into the belt below through the maintainer, and the back of lining up is pulled down old carrying roller by other maintainer with carrying on the back the jack-up belt and maintaining then, newer carrying roller is put into the frame draw-in groove and is in place.Because present conveyer belt is all very wide; Its weight is very big; And on-the-spot belt all is in tension, and strength just can and maintain belt jack-up so the maintainer need cost a lot of money, and therefore changing a carrying roller needs more than 4 people at least; Owing to working strength causes the maintainer to be short of physical strength very greatly, work rate is low often.There are a lot of veteran maintainers also to think good multi-method, comprise by some instruments such as jack, chain blocks being used, but, can not satisfy actual carrying roller and change demand finally all owing to reasons such as thing heaviness, use inconvenience, inefficiencys.
Summary of the invention
The objective of the invention is to overcome the deficiency that prior art exists; And a kind of carrying roller changing device more of ribbon conveyer of simple in structure, easy to use, highly versatile is provided; It is to utilize ribbon conveyer carrying roller pack support to be these characteristics of angle steel, a kind of new tool that designs cleverly.
The objective of the invention is to accomplish through following technical scheme, it comprises that one can easily be fixed to the stake body on the carrying roller frame, and it can carry out corresponding adjusting according to the big I of carrying roller frame; One side of said stake body has been installed a cover post rod mechanism, in this post rod mechanism, is provided with the trapezoidal screw transmission device that moves up or down on can be perpendicular to carrying roller frame direction supporting trapezoidal nut effect under.
The connection gusset that described stake body disposes the support of the bolt that is used for fixing by one and connects fairlead in the post rod mechanism constitutes; Trapezoidal screw is screwed in the said fairlead, is arranged in the top of fairlead and the supporting trapezoidal nut of trapezoidal screw of trapezoidal screw transmission device and is provided with one to realize that screw rod makes progress, the two-way ratchet device of downward rapid movement.
Described trapezoidal screw transmission device comprises a trapezoidal screw; Be provided with one through bearing pin T type top board that connect, that contact with belt conveyor in the upper end of this trapezoidal screw; It can increase the contact area of top board and belt conveyor, and this top board can be adjusted with the shaping angle of belt automatically.
It is little, in light weight, simple in structure, easy to use and carry, safe and reliable that the present invention has a volume, highly versatile, operating efficiency improves greatly, can fine satisfied actual carrying roller replacing demand etc. characteristics; Use it can make things convenient for, change easily that ribbon conveyer is multi-form, the carrying roller of different size, to have reached province people, laborsaving, timesaving purpose.

The specific embodiment
To combine accompanying drawing that the present invention is done detailed introduction below: as shown in the figure, it comprises that one can easily be fixed to the stake body 1 on the carrying roller frame 4, and it can carry out corresponding adjusting according to the big I of carrying roller frame; One side of said stake body 1 has been installed a cover post rod mechanism 2, in this post rod mechanism 2, is provided with the trapezoidal screw transmission device 3 that moves up or down on can be perpendicular to carrying roller frame direction supporting trapezoidal nut effect under.
The connection gusset 13 that described stake body 1 disposes the support 12 of the bolt 11 that is used for fixing by one and connects fairlead 21 in the post rod mechanism 2 constitutes; Trapezoidal screw 31 is screwed in the said fairlead 21, is arranged in the top of fairlead 21 and the trapezoidal screw 31 supporting trapezoidal nuts 32 of trapezoidal screw transmission device and is provided with one to realize that screw rod makes progress, the two-way ratchet 33 of downward rapid movement.
Described trapezoidal screw transmission device 3 comprises a trapezoidal screw 31; Be provided with one through bearing pin 22 T type top boards 23 that connect, that contact with belt conveyor in the upper end of this trapezoidal screw 31; It can increase the contact area of top board and belt conveyor, and this T type top board 23 can be adjusted with the shaping angle of belt automatically; Replacing method for different carrying rollers is seen Fig. 2,3,4, shown in 5, because of structure is identical, is not therefore done repeat specification.
Shown in Figure 1, at first support 12 is placed in institute and will changes on the carrying roller frame 4 bolt 11 of screwing.Then trapezoidal screw 31 is upwards carried and made T type top board 23 cling to belt conveyor 5; Then on earth with trapezoidal nut 32 usefulness hand-screws; Then realize that through rotating two-way ratchet 33 trapezoidal screw moves upward fast again, thereby belt conveyor 5 is risen needed height.Last just demolition, installation carrying roller 6 easily.
