Abstract
The utility model discloses a slack-rope detecting device, and relates to the technical field of safety protection devices during heavy objects lifting process. The device comprises a housing and a limit switch, wherein a base and an upper top cover are connected to the housing; the limit switch is mounted on the base in the housing; a limit device comprising a guide wheel, a top rod, a limit guiding block and a spring is arranged in the housing; the guide wheel is rotationally connected to the upper end part of the top rod extending out of the upper top cover through a guide wheel shaft; the upper part of the top rod can slide along the upper top cover; and the lower end of the top rod is close to the limit switch. The guide wheel is abutted against a steel wire rope, and the top rod is lifted upwards through the pressure generated by the tightening of the steel wire rope; and when the top rod is in the lifting state, the limit switch is in a non-compression state and is out of operation. As long as the pressure of the steel wire rope on the guide wheel is reduced due to malfunction, slackness or breakage, the compressed spring bounces up, the top rod moves downwards, and the lower end of the top rod closely extrudes the limit switch to switch on the limit switch, therefore, a system alarms and a power system automatically stops working, thereby playing the protection function.
Description
Technical field
The utility model relates to lifting weight safety guard technical field, relates in particular to a kind of disconnected slack rope detecting device of steel rope damage that can prevent to hang.
Background technology
Steel rope is the flexible cable that twists into many or multiply finer wire; twist with the fingers into thigh by the multilayer steel wire; be the center again with the wire rope core; by the helically wound rope of some thighs; it supplies to promote in material handling machinery; traction; the usefulness of fixed strain and carrying; the intensity height of steel rope; from heavy and light; stable working; all adopt steel rope as suspender or traction medium in a lot of occasions, yet use is because on hanging object constantly carry out; down; a left side; orientation such as the right side move, and cause rope wear or aging relatively more serious; cause steel rope loosening through regular meeting; because the loosening of steel rope tend to cause rope-broken accident, thereby can cause the generation of grave accident, thus between slack rope one of topic very serious between topic; though the rope creep protection device also occurred at present, all do not promoted the use of because of its complex structure poor reliability.
Summary of the invention
It is a kind of simple in structure, safe and reliable that the purpose of this utility model is to provide, and is easy for installation and maintenance, and can guarantee to promote, transport the slack rope detecting device of equipment safety operations such as traction.
The technical scheme that the utility model is adopted for achieving the above object is:
A kind of slack rope detecting device comprises shell, limit switch, is connected with base and upper top cover on the shell, is provided with inhibiting device in the shell, it is characterized in that: described limit switch is installed on the interior base of shell; Inhibiting device is made up of guide wheel, push rod, spacing orienting lug, spring, guide wheel is rotationally connected with the end, upper end of the push rod that is stretched out by upper top cover by guide wheel shaft, can slide along upper top cover in push rod top, the bottom of push rod is close to the transmission levers of limit switch, can slide along the endoporus of spacing orienting lug in the bottom of push rod, the position that is positioned at spacing orienting lug top on the push rod is provided with fixed block, and described spring is between fixed block and upper top cover.
Install for convenience, spacing orienting lug described in the utility model is fixed on the shell.
For convenience the outer amplification distance of guide wheel is regulated, to meet installation requirement, the guide wheel shaft between guide wheel described in the utility model and the push rod is provided with axle sleeve.
For safety and convenient the adjustment, limit switch described in the utility model adopts the little stroke travel switch of low voltage, and the stress point of the transmission levers of travel switch and push rod lower end are tangent, and the pig-tail wire of travel switch is electrically connected with vital circuit.
For spring is kept greater than the desired elastic force of limit switch, and according to the difference of spring force, spring is carried out length regulate, fixed block described in the utility model and push rod bearing fit are anchored on the push rod with screw.
The slack rope detecting device that the utility model provides, guide wheel is close proximity on the steel rope, pressure when utilizing steel rope to tighten, push rod is upwards lifted, extruding by fixed block and push rod makes spring be in compressive state, because the transmission levers closed contact of push rod lower end and limit switch, push rod lifts the state lower position switch and is in no compressive state, and limit switch is not worked.In case steel rope relaxes owing to fault or decreases disconnected; pressure to guide wheel reduces; compressed spring is upspring; push rod moves downward; closely push the transmission levers of limit switch in the effect lower push rod lower end of elastic force; thereby starting limig switch makes system alarm and power system is quit work automatically, plays a protective role.When the steel rope reparation, to the pressure recovery of guide wheel, push rod is upward movement still, and spring also is in compressive state, the system recovery previous status.
The beneficial effects of the utility model are:
1, the slack rope detecting device is rational in infrastructure, can open and close adjusting with the degree of tightness state of steel rope;
2, the slack rope detecting device is simple in structure, is easy to install and maintenance, and is safe and reliable.
3, slack rope detecting device noise is little, and is highly sensitive, and deceleration and stopping performance is good, and is applied widely, highly versatile.
