Abstract
The utility model relates to an overload protection device for a suspended basket or a hoist in altitude operation, which comprises a baseboard of the suspended basket or the hoist, a bracket of the suspended basket or the hoist, and at least two spring bodies. The baseboard and the bracket arranged under the baseboard are connected by the at least two spring bodies; a switch striking plate is arranged at the middle of the baseboard; a switch with a signal wire is arranged on the bracket at a position where the bracket corresponds to the switch striking plate. The overload protection device for a suspended basket or a hoist in altitude operation has the advantages of not only having a simple structure, a low cost, but also having a more stable performance, a low failure rate and more convenience in assembly and maintenance.
Description
Technical field
The utility model relates to a kind of overload protection device, relates in particular to a kind of overload protection device that is used for aerial work basket or elevator.
Background technology
Aloft work is the high work of a kind of danger, therefore requires the hanging basket of high-rise working or elevator to have very high safety prevention measure.Hanging basket or elevator are worked exceeding under the specified load situation, can influence the safety and the work life of equipment, even influence personal safety.
In the prior art according to patent (application number: 200920105334.X, Granted publication number: CN201343424) described, adopt the sensor acquisition load information that is loaded under the tested device base plate, signal imports control unit into, judge overload information by the control unit comparison, control.
But the problem that such structure exists is:
The first, machinery and electrical structure are complicated, and the components and parts fault rate is higher in the use.
The second, owing to use analog signal transmission, in transmission course, signal is easily disturbed, causes and weighs inaccurate or misoperation.
Three, use the accuracy requirement height of components and parts, the processing and fabricating cost is higher.
Summary of the invention
The utility model technical issues that need to address have provided a kind of overload protection device that is used for aerial work basket or elevator, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: the base plate of hanging basket or elevator, carriage; Also comprise: at least two elastic bodys; Described at least two elastic bodys link together the carriage under described base plate and the base plate; In the middle of described base plate, settle a switch to hit plate; On described carriage and to the position that inductive switch hits plate, settle a switch that has a signal wire (SW).
Compared with prior art, the beneficial effects of the utility model are: not only structure is simpler, and is with low cost, and performance is more stable, and fault rate is low, and it is more convenient that repair and maintenance are installed.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the birds-eye view of Fig. 1;
Fig. 3 is an A place enlarged drawing among Fig. 1.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
By Fig. 1, Fig. 2, Fig. 3 as seen: the utility model comprises: the base plate 1 of hanging basket or elevator, carriage 6; Also comprise: at least two elastic bodys 2; Described at least two elastic bodys 2 link together the carriage 6 under described base plate 1 and the base plate 1; In the middle of described base plate 1, settle a switch to hit plate 3; On described carriage 6 and to the position that inductive switch hits plate 3, settle a switch 4 that has a signal wire (SW).
Described switch 4 is placed on the switch bracket 5 in the carriage 6.
Described switch 4 is to be placed on the switch bracket 5 by screw 8.
Described switch bracket 5 cooperates mounting hole with screw 8 be slotted hole.
Described at least two elastic bodys 2 are to be fixed between base plate 1 and the carriage 6 by bolt 7.
Overload protection device of the present utility model comprises the elastic body that is installed between equipment under test base plate and the carriage, is used for converting the load on the base plate to linear distance; And switching device, be used to detect the elastic body compression distance, when reaching overload point, switch motion and with signal by signal wire transmits to the control system of equipment, implement overload protection.
Use bolt that elastic body is fixed between base plate and the carriage in the utility model.Switch is installed near base plate geometric centre position is hit plate, near carriage geometric centre position switch bracket is installed, switch hits plate and switch bracket is corresponding up and down, also commutative position.With screw switch is installed on the switch bracket, switch bracket is opened slotted hole, and switch can carry out upper-lower position by the slotted hole on the switch bracket to be regulated.When switch was installed, its contact vertically pointed to switch and hits plate.
Before the equipment operation, must carry out overload protection and set.To cross load carrying ability and place on the equipment bay, the up-down adjustment switch position makes its contact and switch hit that plate contacts and switch motion, and switch is screwed in this position.To cross load carrying ability and move away from base plate, will cross load carrying ability again and place on the base plate, whether validation switch shifts to an earlier date or is failure to actuate.If switch shifts to an earlier date or is failure to actuate, need readjust the switch position with reference to said method, when weight reaches overload point, switch motion.
During equipment operation; if overload condition occurs; switch motion; and signal transferred to apparatus control system, report to the police by control system control warning device, and the arrestment operation; until being unloaded to overload point when following; equipment just stops to report to the police and recovering normal working, reaches the purpose of overload protection, the safety that has improved equipment greatly.
Claims (5)
