Description

For changing the device of snub pulley

Technical field

The utility model relates to the device of changing carrier roller of belt conveyer, specifically a kind of for changing snub pulleyDevice.

Background technology

Belt-conveying is a kind of application means of transportation very widely, especially in chemical enterprise, used in a large number,Be the emphasis equipment in chemical enterprise, will cause whole production line to stop if there is fault. The conveying of belt is upper and lowerUnder the support of carrying roller, carry out, the damage of carrying roller not only can affect the transmission of belt but also can produce wearing and tearing to belt, but severalThe long belt of more than hundred kms can not be because the damage of several carrying rollers and replacings of stopping, and driving can cause again belt gradually to damage by forceBad. The replacing if be in operation, traditional substitute mode is manually with crowbar etc., operating belt to be levered up, another employeeCarrying roller is taken out and changed, and will there is very large potential safety hazard in such substitute mode, and therefore employee sustains a severe injury possibly,Produce great security incident.

Summary of the invention

The purpose of this utility model is for the deficiencies in the prior art, provides a kind of for changing the device of snub pulley, moreChange carrying roller safely and fast, can reduce the spoilage of belt, maintain the driving rate of production.

For achieving the above object, the utility model has adopted following technical scheme: comprise and promote carrying roller and be used for carryingThe left and right lifting device that rises the lifting of carrying roller two ends, each lifting device comprises rotation hand wheel, lift-bolt and travel(l)ing rest, revolvesChange hands wheel and be fixed on lift-bolt upper end, lift-bolt is with travel(l)ing rest to be threaded, and each travel(l)ing rest is removably solidFix on conveyer one side crossbeam and lift-bolt is vertically arranged, lift-bolt lower end is connected with rotationally for hanging and carriesRise the hook of carrying roller end part rotating shaft.

Further, travel(l)ing rest one side is provided with first slot that can embed conveyer crossbeam, and the width of the first slot is largeIn the width of crossbeam, the fastening screw that the upper and lower wall outer end of the first slot is provided with locating hole and coordinates with locating hole.

Further, travel(l)ing rest is " work " character form structure, and the first slot and the conveyer crossbeam of travel(l)ing rest one side are joinedClose, in the second slot of opposite side, be provided with and the nut of lift-bolt threaded engagement, on the upper and lower wall of the second slot of placing nutHave the through hole that can pass through for lift-bolt.

The beneficial effects of the utility model are: can be movably arranged on the crossbeam of ribbon conveyer both sides by arrangingTravel(l)ing rest, lift-bolt, can upwards promote the lifting carrying roller that is placed on belt below, thereby realize the online subiculum of changingRoller, the production efficiency of raising ribbon conveyer. Secondly,, for the ribbon conveyer of continuous operation, can change in time notThe snub pulley turning, can reduce belt wearing and tearing, extends the service life of belt, increases maintenance safety. Again, this device not onlySimple and compact for structure, and be convenient to install on crossbeam, and lightweight, be easy to carry and easy for installation.

Detailed description of the invention

Below in conjunction with accompanying drawing, the technical scheme in the utility model embodiment is clearly and completely described.

As shown in Figure 1, this practicality comprise promote carrying roller 3 and be used for by promote carrying roller 3 two ends upwards the left and right of lifting carryRise device 2,1, each lifting device comprises that rotation hand wheel 11, lift-bolt 12 and travel(l)ing rest 13 form. Rotation hand wheel 11 is solidFix on lift-bolt 12 upper ends.

Travel(l)ing rest 13 is " work " character form structure, and all there is first, second slot 131,132 both sides. Travel(l)ing rest 13 1 sidesThe first slot 131 can embed conveyer crossbeam 4, travel(l)ing rest 13 is removably fixed on crossbeam 4 by the first slot 131Upper, the width of the first slot 131 is greater than the width of crossbeam 4, the upper and lower wall outer end of the first slot 131 be provided with locating hole and withThe fastening screw 14 that locating hole coordinates, is limited to travel(l)ing rest 13 on crossbeam 4 by fastening screw 14; Travel(l)ing rest 13 anotherIn the second slot 132 of side, be placed with and the nut 15 of lift-bolt 12 threaded engagement, nut 15 can movablely be placed or pass throughBe weldingly fixed in the second slot 132, on the upper and lower wall of the second slot 132 of nut 15, have and can supply lift-bolt 12 pass throughThrough hole, lift-bolt 12 through the second slot 132 upper and lower walls pass through be threaded with the nut 15 being placed in slot. PromoteScrew rod 12 lower ends are connected with the hook 16 that promotes carrying roller 3 end part rotating shaft 31 for hanging rotationally.

While changing snub pulley, the travel(l)ing rest 13 of left and right lifting device 1,2 is separately fixed to snub pulley 7 one to be replacedOn the conveyer both sides crossbeam 4 of side, lift-bolt 12 is connected with nut 15 through the second slot 132 of respective activity support, thenTenaculum 16 is connected to lift-bolt 12 lower ends, but is placed on below lower belt and by the rotating shaft at two ends 31 promoting carrying roller 3Be suspended on the tenaculum 16 of left and right lifting device 1,2. Then the rotation hand wheel 11 that rotates left and right lifting device 1,2 makes to promote spiral shellBar 12 rises, and by linking up with 16, lifting carrying roller 3 is upwards lifted to descending section of belt 5, as shown in Figure 2, replaceable corresponding underCarrying roller 7. In figure, piece number 6 is up section of belt.
