Abstract
The utility model relates to spring rod-pulling type mechanical load proterctive equipment; described load protection device is provided with pull bar, spring, tablet, stay bearing plate and base; described pull bar passes from spring; the top of pull bar is provided with lock dog; pull bar lower end is connected with steel cord ends; the top of described spring is provided with tablet; briquetting is provided with between described tablet and lock dog; described tablet is furnished with proximity inductor; the bottom of described spring is connected with stay bearing plate, and base is provided with tilting bearing and screw rod.Its advantage is: spring and proximity sensor combine and be used for crane load protection, the effect that proximity sensor itself does not stress by the utility model, only detect the change in location of tablet, substantially prolongs its service life; Steel cord ends is connected with the pull bar with spring, in the impact accelerating can reduce instantaneously system that hoists of goods, makes testing result more accurate, substantially increases system stability and accuracy.
Description
Technical field
The utility model relates to a kind of load protector, specifically, is spring rod-pulling type mechanical load proterctive equipment.
Background technology
The load protector of current crane hoisting mechanism is at position setting pressure sensors such as reel base, sheave shafts substantially; the sensor devices such as overweight killer; by the distortion that force acting on transducer produces; export the analog signal corresponding to weight and detect load; because weight sensor is for a long time by the effect of reverse load; itself easily damages and et out of order; and when being subject to the effect of impact load; due to the increase of momentary duty; easy generation flase alarm; reliability and the accuracy of testing result are poor, have impact on the effect of load protection.
Chinese patent literature CN201320462246.1, discloses a kind of overload protection device of tower crane peculiar to vessel, and what this device adopted is pressure sensor, still exists and has damaged the problem with poor reliability.About stable, the reliable mechanical load proterctive equipment accurately of detection, yet there are no report.
Summary of the invention
The purpose of this utility model is for deficiency of the prior art, provides a kind of spring rod-pulling type mechanical load proterctive equipment.
For achieving the above object, the technical scheme that the utility model is taked is:
Spring rod-pulling type mechanical load proterctive equipment, described load protection device is provided with base, stay bearing plate, spring, tablet, pull bar, described base is provided with tilting bearing and screw rod, the top of described tilting bearing is provided with stay bearing plate, described stay bearing plate is connected with the lower end of spring, the upper end of described spring is connected with tablet, described tablet is furnished with proximity inductor, described pull bar passes from the centre of tilting bearing and spring, the top of described pull bar is provided with lock dog, pull bar lower end is connected with steel cord ends, briquetting is provided with between described lock dog and tablet.
Described proximity inductor is arranged on the periphery of spring.
The utility model advantage is:
1, spring and proximity sensor combine and are used for crane load protection, the effect that proximity sensor itself does not stress by the utility model, only detect the change in location of tablet, substantially prolongs its service life.
2, steel cord ends is connected with the pull bar with spring, in the impact accelerating can reduce instantaneously system that hoists of goods, makes testing result more accurate, substantially increases system stability and accuracy.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the utility model spring rod-pulling type mechanical load proterctive equipment.
Detailed description of the invention
Below in conjunction with accompanying drawing, the detailed description of the invention that the utility model provides is elaborated.
The Reference numeral related in accompanying drawing and component part as follows:
1. base 11. tilting bearing
12. screw rod 2. springs
21. stay bearing plate 22. tablets
23. proximity sensor 24. briquettings
3. pull bar 31. lock dog.
Embodiment
Please refer to Fig. 1, Fig. 1 is the structural representation of the utility model spring rod-pulling type mechanical load proterctive equipment.Described load protection device is provided with base 1, stay bearing plate 21, spring 2, tablet 22, pull bar 3, described base 1 is provided with tilting bearing 11 and screw rod 12, the top of described tilting bearing 11 is provided with stay bearing plate 21, described stay bearing plate 21 is connected with the lower end of spring 2, the upper end of described spring 2 is connected with tablet 22, described tablet 22 is furnished with proximity inductor 23, described proximity inductor 23 is arranged on the periphery of spring 2, described pull bar 3 passes from the centre of tilting bearing 11 and spring 2, the top of described pull bar 3 is provided with lock dog 31, pull bar 3 lower end is connected with steel cord ends, briquetting 24 is provided with between described lock dog 31 and tablet 22.
When steel rope there being load, pull bar 3 under tension acts on briquetting 24, power is applied on spring 2 by tablet 22 by briquetting 24, there is deformation in spring 2, tablet 22 position is changed, when not overloading, tablet 22 stops at the top of proximity sensor 23, and now proximity sensor 23 does not have signal to produce; When overload crane, tablet 22 can move downward and cross proximity sensor 23, and now proximity sensor 23 outputs signal to PLC control unit, thus realizes the object of overload protection.Tilting bearing 11 can reduce the impact of hunting of load to load protection device, and screw rod 12 can prevent wire rope rotating.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model method; can also make some improvement and supplement, these improve and supplement and also should be considered as protection domain of the present utility model.
