Abstract
The utility model discloses a load limiting device for a hanging basket and relates to a building mechanical hanging basket. The load limiting device for the hanging basket comprises an engine base. A pull rod runs through the engine base up and down. A connecting plate is fixed at the tail end of the pull rod at the lower part of the engine base; disc springs are arranged on the pull rod between a connecting rod and the engine base. The other end of the connecting plate is pressed on a micro switch fixed relative to the engine base in a contact way. The micro switch is connected with a cable. The load limiting device for the hanging basket has compact structure, is convenient to install and is accurate and timely to return. Moreover, the accuracy can be controlled by increasing and decreasing the number of the disc springs.
Description
Technical field
The utility model relates to a kind of vehicle for construction, the mechanical type load carrying ability killer that particularly a kind of hanging basket is used.
Background technology
Hanging basket is a kind of vehicle for construction now commonly used, is widely used in the work progress such as decoration, construction of skyscraper.In actual use, usually can overload and the user is ignorant, cause danger easily.Existing load limiter all is that hoisting crane is used usually, is connected on the guiding principle rope of winch, and it is very difficult that this class load limiter cooperates hanging basket hoisting to use.Existing in addition many load limiters all are to use sensor, and cost is higher, complex structure.
The utility model content
The purpose of this utility model is a kind of weight load limiter that is suitable for present gig hanging basket of design, and simple in structure, and reliable operation can also be regulated limit for tonnage weight.
This load limiter contains organic block, there is a pull bar to run through about the support, end below the support of pull bar, be fixed with connecting plate, on the pull bar, be provided with belleville spring between connecting rod and the support, the contact of the other end of connecting plate is pressed in one with respect on the fixing micro-switch of support, and micro-switch is connected with control cable.
In order to make the adjustable in pressure of belleville spring, just regulate default nominal payload, preferred scheme is to be enclosed within on the pull bar at belleville spring, pull bar is provided with and tightens nut belleville spring is fixed on the pull bar.Regulate pre-load nut and just can regulate the elastic force of belleville spring, also just can regulate default nominal payload support.
Connecting plate is provided with set screw, and the end of this set screw is pressed on the micro-switch.
Preferably: be connected with the electric bell power supply on the open contact of micro-switch.Certain alerting signal is provided when can make limit for tonnage, and when micro-switch was touched because of hanging cradle overload, it is closed that often the opening of micro-switch got an electric shock, and electric bell gets electric alarm.
Preferably below support, waterproof jacket is set, belleville spring, connecting plate, micro-switch are arranged in this waterproof jacket, can tackle outdoor worse working environment.
The pull bar of load limiter of the present utility model is connected the bottom of hanging basket hoisting, and the cable of load limiter is connected on the electric cabinet of hanging basket.When the actual measurement weight (AMW) of hanging basket when rated weight is following, the pull bar of this load limiter is pressed on the support under the belleville spring effect, can not produce longitudinally to move, micro-switch can be touched; When the load carrying ability of hanging basket surpasses default load carrying ability, pull bar continues the compression belleville spring, and drives connecting plate and move up, and up to touching micro-switch, makes micro-switch produce on-off action with control hanging basket control circuit power-off protection.
This hanging basket load limiter mechanism compactness, easy for installation, return accurately and timely.While installs as the belleville spring of the reference component of limit for tonnage and changes conveniently, and the precision of whole load limiter can be controlled by the quantity of increase and decrease belleville spring, when having relatively high expectations precision, needs only many some belleville springs of dress.
Description of drawings
Fig. 1, constructional drawing of the present utility model.
Fig. 2, Fig. 1 lateral plan.
Among the figure, 1---pull bar, 2---bolt, 3---orienting sleeve, 4---support, 5---waterproof jacket, 6---micro-switch, 7---belleville spring, 8---packing ring, 9---jam nut, 10---connecting plate, 11---the cable screwed pipe, 12---control cable, 13---set screw.
The specific embodiment
As Fig. 1, Fig. 2, support 4 of the present utility model is a plane, is provided with lug above, and the below is provided with fully enclosed waterproof jacket 5, forms a cavity.Pull bar 1 runs through outside support 4 in the waterproof jacket 5 of packing into, and, also have the hole on the pull bar 1, have one spacingly to captive joint by a bolt 2 and orienting sleeve 3 and support.Be provided with jam nut 9 below pull bar 1, this jam nut 9 is fixed on belleville spring 7 on the pull bar 1, and belleville spring 7 two are withstood support 1 and jam nut 9 respectively, also is provided with packing ring 8 between jam nut 9 and the belleville spring 7.Behind pull bar 1 lower end, the jam nut 9, be fixed with a connecting plate 10, the other end of connecting plate 10 is fixed with a set screw 13, and set screw 13 is withstood micro-switch 6.Described micro-switch is stationkeeping with respect to support 4, and in the present embodiment, micro-switch 6 is fixed by the cable screwed pipe 11 and the fixed relationship of waterproof jacket 5.Control cable 12 is guided the outside of this load limiter with after micro-switch 6 is connected into through cable screwed pipe 11, is connected on the Main Control Tank of gig.
During use, this load limiter is installed on the platform of hanging basket, and pull bar 1 is connected the bottom of the gig of hanging basket, but the top of gig and straight skidding after the hanging basket platform is connected.According to no load request, tighten jam nut 9, give belleville spring 7 certain predetermincd tension, and the position of the good set screw 13 of corresponding setting, allow it be pressed on the micro-switch 6.The normally closed electric shock of micro-switch 6 connects governor circuit, connects an electric bell or other acousto-optic equipment on the open contact.When load surpasses preset weight, the pulling force that pull bar 1 is subjected to is greater than the elastic force of belleville spring 7, and connecting plate 10 is just driven toward top offset by pull bar 1, drives set screw 13 and touches micro-switchs 6, and after micro-switch 6 actions, open contact disconnects and makes whole hanging basket stop to rise; Normally closed electric shock closure is reported to the police electric bell.
