Abstract

The utility model discloses a special dissembling tool for a return roller, the aim of which is to overcome the problems of labor-wasting, time-wasting, and insecurity because the return idler is disassembled by using a tripod and a hand pulling gourd in the prior art. A supporting seat is fixedly arranged on a cross beam which is arranged on the upper part of a belt conveyer return roller, one end of a long pressing rod is provided with a handle, the point of the central part of the long pressing rod is leaned toward a shaft head of the return roller and is hinged and supported on the supporting seat, and one end of the pressing rod near the shaft head of the return roller is provided with a cord chain of which the tail end is provided with a hook. When the utility model is used, the cord chain which is arranged on the installed tool is wound on the end part of the return roller, the hook of the cord chain is hooked in a self chain link hole to pocket a roller head, the handle of the pressing rod is pressed downward, and the return roller can be brought out from a groove under the action of lever force. Because the supporting seat is arranged on the existing cross beam, the utility model has the advantages of stable support, low center of gravity, and high safety; furthermore, the roller head can be brought out by pressing the handle in 5 minutes by one person, the utility model also has the advantages of time saving, labour saving, and high efficiency, and the utility model satisfies the producing requirements. The special dissembling tool for a return roller has the advantages of simple structure, low manufacturing cost, and strong operability.

Description

Return idler dismounting specific purpose tool

Technical field

The utility model belongs to instrument, specifically a kind of specific purpose tool of large-scale belt feeder carrying roller for convenience detach.

Background technology

Harbour handling at present such as fragmentary goods such as coal, ore in sand form generally are to carry with LARGE SIZED.For guaranteeing the normal operation of belt conveyer, one of vitals on the machine---return idler will guarantee to be in all the time normal duty.Because the upwards of movement of harbour goods is big, used large-scale belt feeder is just many, and its maintenance capacity is also big.To the repairing of return idler, generally be it to be disassembled transport to repair workshop, install and use again after fixing.Because the weight of every return idler is about about 100 kilograms, and the installation of carrying roller on belt feeder, be with the carrying roller two ends prop up with bearing the spindle nose that is, is with opposite planar be inserted in the draw-in groove that is fixed in hanger in the belt feeder framework fixing, because of fixing tight dismounting difficulty.The dismounting mode of technology is now, propping up the tripod that hangs with chain block on the framework of carrying roller two ends belt feeder respectively, be bundled on the hook that the spindle nose inboard hangs over chain block with rope, adopt the mode that pulls pickaback to tear open, pulling down an above-mentioned carrying roller needed for four personal work half an hours.Belt feeder is many, and eligible for repair carrying roller is also many, effort, time-consuming, and the maintenance personal often is too busy to do it and delays production; And prop up on existing framework with tripod, balance when its three leg is difficult in hoisting heavy when assigning in case that tripod props up bad generation is crooked, is not to break carrying roller, smash belt feeder, and the people that damages exactly is very dangerous.

The utility model content

Technical problem to be solved in the utility model is, overcomes in the prior art with tripod and chain block dismounting return idler effort, time-consuming, unsafe problem, and a kind of return idler dismounting specific purpose tool is provided.

In order to solve the problems referred to above that prior art exists, the utility model is to adopt following technical proposals to realize: on the crossbeam on belt feeder return idler top, be installed with bearing, one end is the microscler depression bar of handle, its deflection return idler spindle nose place, middle part is hinged on bearing, and the rope chain of terminal buckle is installed at an end of the nearly return idler spindle nose of depression bar.

Described depression bar is hinged on bearing, be on the base plate of bearing, be fixed with two vertical parallel, the band relative opening gripper shoe, corresponding position on depression bar is fixed with otic placode with holes, and otic placode is inserted between the two relative gripper shoes, and fulcrum passes two gripper shoes is connected its hinge with hole on the otic placode;

Described depression bar is hinged on bearing, be that a vertical gripper shoe with holes is arranged on bearing, be fixed with two parallel otic placodes with holes with the corresponding position of supporting plate hole on the depression bar, two otic placodes are buckled in the gripper shoe both sides corresponding with it, and fulcrum passes two otic placodes is connected its hinge with hole on the gripper shoe;

The rope chain that described depression bar one end is installed is to be fixed with ring on the nearly carrying roller termination of depression bar, and an end of rope chain Wugou is through in the ring.

During use, with the end of the rope chain on the mounted instrument around the backhaul roller, the hook of the last drag-line end of the chain makes it collude in the link aperture of self the roller camail is lived, and with the handle end of subordinate moulded rod, the backhaul roller is proposed to unload in groove under the effect of lever force.

Advantage of the present utility model and good effect be, above-mentioned specific purpose tool has utilized the crossbeam of belt feeder itself, and the bearing of its specific purpose tool is installed on the existing crossbeam, therefore support firm and center of gravity low, safe and reliable; After specific purpose tool installs, only need the handle of people's moulded rod, can easily the roller head be proposed to pull down from draw-in groove in 5 minutes, save time, laborsaving, improved work efficiency, won maintenance time, satisfied the needs of loading and unloading productions.Above-mentioned tool construction is simple, and manufacturing cost is low, and is workable.

Fig. 2 is the schematic diagram of return idler spindle nose among Fig. 1;

Fig. 3 is the partial schematic diagram of buckle rope chain among Fig. 1.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

Among Fig. 1, on the crossbeam 9 on belt feeder return idler 1 top, be installed with bearing 10, right-hand member is the microscler depression bar 7 of handle 7.1, and the spindle nose 1.1 (referring to Fig. 2) of the nearly return idler of taking back in its middle part 1 is located hinged on bearing 10.

The hinged mode of microscler depression bar 7 can be, bearing 10 is the gripper shoes 10.2 that are fixed with two vertical parallel, band relative openings on its base plate 10.1; Below depression bar 7 with gripper shoe 10.2 corresponding positions, be fixed with otic placode with holes 7.2, otic placode 7.2 is inserted between the two relative gripper shoes 10.2, and fulcrum 8 passes the fulcrum that lever is made in hole on two gripper shoes 10.2 and the otic placode 7.2, with otic placode 7.2 and gripper shoe 10. relative flexible connections; Also can be that gripper shoe 10.2 on bearing 10 is one, the otic placodes 7.2 below the depression bar 7 be two, and correspondence is buckled together mutually, does the fulcrum flexible connection with the hole that fulcrum 8 passes on gripper shoe 10.2 and the otic placode;

Be fixed with ring 4 on the top of spindle nose 1.1 1 ends of depression bar 7 nearly return idlers 1, rope chain 3 head ends of terminal buckle 3.1 (referring to Fig. 3) are through in the ring 4 and are installed on the depression bar 7.

Among Fig. 2, on the spindle nose 1.1 of return idler 1, be provided with the flat horizontal surface 1.2 in the draw-in groove 5 (referring to Fig. 1) that may be stuck on the belt conveyer hanger 6.
