Abstract
The utility model relates to hoisting equipment, in particular to a mounting device of a crane lifting limit switch, which comprises a drum shaft, a drum shaft support, a limit switch, a limit switch connecting frame and a limit switch coupling. The mounting device of a crane lifting limit switch is characterized in that the limit switch coupling comprises a disc connecting plate, a driver plate and driving pins, the disc connecting plate is fixedly mounted at the end of the drum shaft, the driver plate is fixed on a limit switch output shaft, the connecting plate is connected with the driver plate via the driving pins, holes for mounting the driving pins are arranged at corresponding positions of the connecting plate and the driver plate, and the limit switch is fixed on the end surface of the drum shaft support via the limit switch connecting frame. The driving pins are utilized to transmit rotation of the crane drum shaft to the limit switch, thereby reducing manufacturing and mounting precisions on the premise of meeting working requirements of the crane. Besides, the mounting device of a crane lifting limit switch has the advantages of simple structure and fine universality.
Description
Affiliated technical field
The utility model relates to weight-lifting equipment, particularly a kind of erecting device of crane hoisting limit switch.
Background technology
Limit switch on the hoist roller is the important component part of reel, and its serviceability and reliability directly affect the serviceability and the safety of the lifting mechanism in the hoisting crane.
At present on hoisting crane, the installation pattern of the limit switch on the reel is: with the bolt group limit switch is fixed on the limit switch supporting base earlier, by the limit switch coupler limit switch and drum shaft are linked together again, then the limit switch supporting base is fixed.This traditional structural shape is very high to the working accuracy and the installation requirement of limit switch coupler, to guarantee the annexation of limit switch and drum shaft.Along with the continuous development of technology, the user is more and more higher to the electrified requirement of hoisting crane, makes the model of limit switch various day by day then, and the universalization of limit switch catcher and limit switch base has been subjected to bigger restriction.Because hoisting crane is the annex of reel group with the drum shaft bearing, and limit switch base is the annex of electric elements, so their supporting use usually can be subjected to bigger restriction.
Summary of the invention
The purpose of this utility model provides that a kind of structure is simple relatively, the erecting device of manufacturing, crane hoisting limit switch easy for installation.
The technical solution of the utility model is: a kind of erecting device of crane hoisting limit switch, comprise drum shaft, drum shaft support, limit switch, limit switch link span and limit switch coupler, it is characterized in that above-mentioned limit switch coupler comprises the discoid connecting panel that is fixedly mounted on the reel axle head, is fixed on dial and the finger that connecting panel, dial are linked to each other on the limit switch output shaft, have the hole that is used to install finger on the correspondence position of connecting panel and dial, limit switch is fixed on the end face of drum shaft support by the limit switch link span.
Above-mentioned connecting panel is by being bolted to the reel axle head.
The utility model is to utilize finger to give limit switch with the rotation transmission of hoist roller axle, so just makes under the prerequisite that satisfies hoisting crane work needs, the accuracy requirement of making, installing is reduced, and have characteristics such as simple in structure, that commonality is good.
Description of drawings
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is the structural representation of the utility model drum shaft axle head;
Accompanying drawing 3 is the left view of the utility model dial.
The specific embodiment
As shown in Figure 1, drum shaft 1 is installed in drum shaft supporting base 11, by bolt discoid connecting panel 2 is arranged on the right side of drum shaft, has bolt hole 8 and the hole 9 that is used for plug pin 4 on the connecting panel 2.Dial 6 is installed on the input shaft of limit switch 7, also have on the dial with connecting panel on be used for the corresponding hole, hole of plug pin.
At first connecting panel 2, limit switch link span 5 are separately fixed on the right side and limit switch 7 of drum shaft during use, then dial 6 is fixed on the input shaft of limit switch, finger is inserted in the hole 9 on connecting panel or the dial, again the limit switch link span is fixed on the drum shaft supporting base.
Claims (2)
1. the erecting device of a crane hoisting limit switch, comprise drum shaft, the drum shaft supporting base, limit switch, limit switch link span and limit switch coupler, it is characterized in that above-mentioned limit switch coupler comprises the discoid connecting panel (2) that is fixedly mounted on drum shaft (1) end, be fixed on limit switch (7) output shaft dial (6) and with connecting panel, the finger (4) that dial links to each other, on the correspondence position of connecting panel and dial, have the hole (9) that is used to install finger, limit switch (7) be fixed on the drum shaft support by limit switch link span (5) or end face.
