Description

Balancer

Technical field:

The utility model relates to a kind of equipment of hanging, and specifically is a kind of being applied on the production line, is used to hang the balancer of operation tools such as electric drill.

Background technology:

General on the streamline of machine-building such as auto production line; we use balancer to hang the certain operations instrument through regular meeting; in use; we generally are fixed on higher place, top, operating position to balancer; operation tool hangs on the steel wire rope of balancer; utilize the pulling force of the volute spring in the balancer operation tool of slinging; when the pulling force of the gravity of operation tool and volute spring reaches balance; at this moment operation tool generally is in top, operating position higher position; people will pull down operation tool in the time of will using operation tool to carry out work; after loosing one's grip; operation tool will rise to original position; reuse and will pull down operation tool once more, so just relatively more inconvenient.

The utility model content:

The technical problems to be solved in the utility model is to provide a kind of can making to pull down the balancer that the operation tool that is in the place, operating position is locked in the place, operating position.

Technical solution of the present utility model is, a kind of balancer with following structure is provided: it comprises procapsid, back casing, main shaft, roller, the roller lining, volute spring and steel wire rope, procapsid is connected with back casing, and the roller lining is connected with roller, procapsid, roller, roller lining and back casing all are enclosed within on the main shaft successively, volute spring is contained in the roller, and the one end is connected with main shaft, and the other end is connected with roller, steel wire rope is wrapped on the roller, the one end is connected with roller, and the other end is connected with the spring hook, and procapsid and back casing top edge are connected with connecting ring and iron chains, wherein, be provided with the retaining mechanism that the operation tool that the spring hook is hung oneself hang is locked in the place, operating position between back casing and the roller lining.

Balancer described in the utility model, wherein, retaining mechanism comprises wheel disc, catch, the catch fixed axis and first spring, wheel disc is connected with the roller lining, the wheel plate edge is provided with the first semicircle boss and the second semicircle boss of two off-centre, be provided with first step in the middle of the first semicircle boss, the first semicircle boss comprises first first a close end away from end and close center of rotation away from center of rotation, be provided with second step in the middle of the second semicircle boss, the second semicircle boss comprises second second a close end away from end and close center of rotation away from center of rotation, catch is provided with deep-slotted chip breaker and the catch head that is used to be stuck on first step or the second step, the catch fixed axis is connected with back casing after passing deep-slotted chip breaker, one end of first spring is connected with catch, and the other end is connected with back casing.

Balancer described in the utility model wherein, is connected with on the back casing and is used to control the switching mechanism whether retaining mechanism uses.

Balancer described in the utility model, wherein, switching mechanism comprises knob and pushing piece, the hole that knob passes on the back cover body wall is connected with pushing piece.

Balancer described in the utility model wherein, is connected with the insurance institution that prevents the spring hook to hang oneself when volute spring breaks suddenly the operation tool hung falls down under the gravity effect on the procapsid.

Balancer described in the utility model, wherein, insurance institution comprises roller cap, safeguard machine, torque spring and second spring, roller cap is connected with roller, circumferentially on the roller cap evenly is provided with a plurality of bending sheets, and safeguard machine and procapsid are hinged, second spring, one end hangs on the safeguard machine, the other end is connected with procapsid, and torque spring is clamped on the main shaft, and withstands on the safeguard machine.

After adopting above structure, compared with prior art, the utility model balancer has the following advantages: because the utility model balancer has retaining mechanism, this retaining mechanism comprises wheel disc, the catch and first spring, and the wheel plate edge is provided with the first semicircle boss and the second semicircle boss of two off-centre, the first semicircle boss comprises first step, first away from the end and the first close end, the second semicircle boss comprises second step, second away from the end and the second close end, catch is provided with the catch head that is used to be stuck on first step or the second step, therefore, when the steel wire rope that hangs operation tool when leaving behind rotates wheel disc, catch head on the catch can slide along the outer wall of the first semicircle boss and the second semicircle boss, when sliding into first step and second step place, the catch head can be stuck on first step and the second step, thereby can make operation tool be locked in the place, operating position, after using operation tool, when needing operation tool to get back to top, operating position higher position, when using operation tool, when needing operation tool to get back to top, operating position higher position, only need toward drop-down steel wire rope one segment distance make wheel disc turn to the catch head be in first near between end and the first step or second near hold and second step between the time, unclamp hand, at this moment wheel disc can rotate under the effect of the pulling force of volute spring in the opposite direction, at this moment the catch head can from first near end and second away between the end or second near end and first away from entering into inwall one side of the first semicircle boss and the second semicircle boss between the end, and slide along the inwall of the first semicircle boss and the second semicircle boss, thereby steel wire rope is recovered in the balancer, and operation tool has been got back to top, operating position higher position.

Being provided with of switching mechanism can allow people's turning knob, drives pushing piece and rotates, and rotates thereby promote catch, makes the catch head on the catch turn to inwall one side of the first semicircle boss and the second semicircle boss, thereby makes retaining mechanism ineffective.

The setting of insurance institution is when volute spring breaks suddenly, at this moment the safeguard chance is rotated under the effect of second spring tension, thereby withstand on an end of the bending sheet on the roller cap, roller can not be rotated, thereby the operation tool of hanging on the balancer can not fallen down, played safe effect.
