Abstract
The invention relates to a built-in load-limiting device. The built-in load-limiting device comprises a steel wire rope, a load-limiting sensing wheel, a sensing box swinging supporting shaft, a swinging sensing box, a rope limiting wheel, a position-limiting fine adjustment screw, a sensing spring, a set screw, a load-limiting fine adjustment screw and a buffer. The rope limiting wheel and the sensing box swinging supporting shaft are fixed on a hanging basket, the load-limiting sensing wheel is hinged to the swinging sensing box and can be rotated, the sensing spring is installed on the load-limiting fine adjustment screw, the load-limiting fine adjustment screw is in contact with the swinging sensing box and fixed on a block, a buffer deenergizing device is fixed on the swinging sensing box, a certain distance is kept between the buffer deenergizing device and the block, when the force applied to the steel wire rope exceeds a limit value, the swinging sensing box is rotated, and the deenergizing device is started, so that the load limiting effect is achieved. The built-in load-limiting device has the advantages that under the working conditions such as overloading and shocking of the hanging basket, a power supply can be disconnected timely, so that the safety protection effect is achieved; the device is light in weight, simple in structure, low in production cost, high in reliability and the like.
Description
Technical field
The invention belongs to the vehicle for construction technical field, relate to a kind of peculiar to vessel or aerial lift device that building is used, specifically a kind of built-in load limitation device.
Background technology
Hanging basket generally is comprised of hitch, track, Rail climbing device, basket body and safety system.The basket body can be along the track cross level walking with vertical mobile, and the staff can arrive each facade of building, is mainly used in steamer, building or structures exterior window and the operations such as outside Wall Cleaning, maintenance.Along with the raising of the existing construction requirements in city, the operations such as regular cleaning and maintenance are carried out in requirement to glass of building window, exterior wall etc.Along with the raising of awareness of safety, hanging basket has also installed safety prevention measure additional in recent years, and inside has also gradually adopted hangs blue load limitation device.
Because load limitation device and the safety prevention measure of hanging basket are very different, so built-in load limitation device must specific design.Thereby research, the built-in load limitation device of development have great importance.
Summary of the invention
The object of the invention is to overcome above shortcomings in the prior art, provides the hanging basket engineering item a kind of built-in load limitation device.
According to technical scheme provided by the invention: described this built-in load limitation device comprises steel rope, limit for tonnage sensing wheel, sensing box swing fulcrum, swings the sensing box, limit rope sheave, spacing micrometer adjusting screw, sensing spring, holding screw, limit for tonnage micrometer adjusting screw and energy disperser; Described limit rope sheave and sensing box swing fulcrum are fixed on the hanging basket.
As a further improvement on the present invention, described swing sensing box is hinged on the sensing box swing fulcrum, and described limit for tonnage sensing wheel is hinged on and swings on the sensing box, and can be around the rotation of sensing box swing fulcrum.
As a further improvement on the present invention, described limit for tonnage micrometer adjusting screw front end is equipped with sensing spring, contact with swing sensing box, and be fixed on the block by holding screw, described energy disperser is threaded connection and is fixed on the block, described breaker device is fixed in by spacing micrometer adjusting screw and swings on the sensing box, and keeps certain distance with block.
As a further improvement on the present invention, described steel rope passes from limit rope sheave and limit for tonnage sensing wheel, when steel rope institute is stressed when surpassing limit value, swings just left-hand revolution of sensing box, and breaker device contact block causes outage, thereby plays the limit for tonnage effect.
The present invention compared with prior art; advantage is: described built-in load limitation device is in the hanging basket operational process; real-time carries out safety detection to hanging basket; in case overload occurs and impact operating mode; can immediately disconnect hanging basket lifting power supply; play the effect of protection workmen safety, this device has that quality is light, simple in structure, productive costs is low and the reliability high.
Description of drawings
Fig. 1 is integral structure schematic diagram of the present invention;
Description of reference numerals: 1-steel rope, 2-limit for tonnage sensing wheel, 3-sensing box swing fulcrum, 4-swing sensing box, 5-limit rope sheave, the spacing micrometer adjusting screw of 6-, 7-sensing spring, 8-holding screw, 9-limit for tonnage micrometer adjusting screw, 10-energy disperser.
The specific embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in Figure 1: the present invention mainly is comprised of steel rope 1, limit for tonnage sensing wheel 2, sensing box swing fulcrum 3, swing sensing box 4, limit rope sheave 5, spacing micrometer adjusting screw 6, sensing spring 7, holding screw 8, limit for tonnage micrometer adjusting screw 9 and energy disperser 10; Described limit rope sheave 5 and sensing box swing fulcrum 3 are fixed on the hanging basket, described swing sensing box 4 is hinged on the sensing box swing fulcrum 3, described limit for tonnage sensing wheel 2 is hinged on and swings on the sensing box 4, and can be around 3 rotations of sensing box swing fulcrum, described limit for tonnage micrometer adjusting screw 9 front ends are equipped with sensing spring 7, contact with swing sensing box 4, and be fixed on the block by holding screw 8, described energy disperser 10 is threaded connection and is fixed on the block, described breaker device is fixed in by spacing micrometer adjusting screw 6 and swings on the sensing box 4, and keep certain distance with block, described steel rope 1 passes from limit rope sheave 5 and limit for tonnage sensing wheel 2, when 1 of steel rope is stressed when surpassing limit value, swings just left-hand revolution of sensing box 4, breaker device contact block causes outage, thereby plays the limit for tonnage effect.
During concrete the application; as shown in Figure 1; described built-in load limitation device working can be divided into overload and impact two kinds of operating modes; described overload operating mode; steel rope 1 passes from limit rope sheave 5 and limit for tonnage sensing wheel 2; stressed when surpassing the safety weight scope; compressed sensing spring 7, by spacing micrometer adjusting screw 6, breaker device starts; described impact operating mode; steel rope 1 is stressed considerably beyond safety weight, and sensing spring 7 can't be protected its breaker device, limits the rotation that swings sensing box 4 by compression buffer 10; thereby the startup breaker device plays the limit for tonnage effect.
