Abstract
A folding-arm anti-rollover device of a working platform of an aerial working truck device which belongs to the anti-rollover device of the working platform of engineering vehicles, and comprises a tilt angle sensor, a connecting rod, an upper arm, an upper arm amplitude cylinder, a lower arm, a lower arm amplitude cylinder and an execution module, wherein the tilt angle sensor is fixed on the upper arm, the upper arm, the lower arm, the connecting rod, the upper amplitude cylinder are hinged with one another, the lower arm amplitude is hinged with the lower arm, and the execute module is connected on a subframe. The utility model has the advantages that real-time detecting, judging and processing system of lifting angle of the arm frame of the aerial working truck, the title angle sensor measures the data of the angles of the working conditions of the arm frame so as to judge whether the arm frame is in the limited range or not and whether the working condition is safe, and then the processing system takes the limit measures and gives an alarm. The utility model has simple structure, low cost, high reliability, and convenient assembly and debugging and direct viewing.
Description
Technical field
The utility model relates to a kind of job platform anti-tilting apparatus of engineering truck, particularly a kind of folding arm-type aerial platform job platform anti-tilting apparatus.
Background technology
At present, at home, because standard mandatory requirement not, aerial platform especially folding-jib aerial platform adopts multi-form fender guard.For example: pendulum adds this device of micro-switch, and its shortcoming is the against shock ability, and reliability is relatively poor.If without limits, jib and the earth angle may cause the job platform leveling system ineffective above safe predetermined angle scope in the course of the work, and then cause overthrow accident, the life security that threatens the operator.
The utility model content
The purpose of this utility model is to provide a kind of: jib and the earth angle can not surpass the folding arm-type aerial platform job platform anti-tilting apparatus of safe predetermined angle scope.
The purpose of this utility model is achieved in that this anti-tilting apparatus comprises: obliquity sensor, connecting rod, upper arm, amplitude oil cylinder, underarm, underarm amplitude oil cylinder and execution module, and obliquity sensor is fixed on the upper arm; All hinged between upper arm, underarm, connecting rod, the upper arm amplitude oil cylinder, underarm amplitude oil cylinder and underarm are hinged, and execution module is connected on the subframe.
Beneficial effect, owing to adopted such scheme, the obliquity sensor of this anti-tilting apparatus utilizes acceleration due to gravity to detect jib and the earth angle, when taking measurement of an angle not in alarm region, promptly the warning angle value of She Dinging is 70 °, the indicator lamp of obliquity sensor is green, no signal output, and Operation Van is in normal working; The arrival critical angle in case take measurement of an angle, switching value of this device output, indicator lamp becomes redness, and execution module restriction dangerous play is also reported to the police, and this state danger of alert operator only allows the direction operation to safety afterwards, and promptly underarm rises, and upper arm falls; This obliquity sensor is set response time≤1 second, when vibrating near the warning angle, can postpone to carry out in two seconds angle acquisition and signal output.Reached the purpose of this utility model.
Advantage: aerial platform jib hoist real-time detection, judgement, the disposal system of angle.Measure the various angle-datas of jib mode of operation in real time by obliquity sensor, judge this moment whether in the predetermined angle scope, whether this state safety, takes restriction and warning by disposal system then.Simple in structure, cost is low, the reliability height, and Installation and Debugging are convenient, and are directly perceived.
Description of drawings
Fig. 1 is a motoring condition constructional drawing of the present utility model.
Fig. 2 is the constructional drawing of the utility model half lifting mode of operation
Fig. 3 is the constructional drawing of the full lifting mode of operation of the utility model.
Among the figure, 1, obliquity sensor; 2 connecting rods; 3, upper arm; 4, upper arm amplitude oil cylinder; 5, underarm; 6, underarm amplitude oil cylinder; 7, execution module.
The specific embodiment
Embodiment 1: this anti-tilting apparatus comprises obliquity sensor 1, connecting rod 2, upper arm 3, amplitude oil cylinder 4, underarm 5, underarm amplitude oil cylinder 6 and execution module 7, and obliquity sensor 1 is fixed on the upper arm 3; All hinged between upper arm 3, underarm 5, connecting rod 2, the upper arm amplitude oil cylinder 4, underarm amplitude oil cylinder 6 is hinged with underarm 5, and execution module is connected on the subframe.
Execution module is made of electromagnetic valve, annunciator and relay.
Described anti-tilting apparatus obliquity sensor 1 is fixed on the upper arm 3; Upper arm 3, underarm 5, connecting rod 2,4 of upper arm amplitude oil cylinder are all hinged, drive upper arm 3 luffings by upper arm amplitude oil cylinder 4 by connecting rod 2; Underarm amplitude oil cylinder 6 drives underarm 5 luffings.Output signal when obliquity sensor 1 measures dangerous angle by the action of execution module 7 restriction upper arm amplitude oil cylinder 4 and underarm amplitude oil cylinder 6, thereby is realized anti-tipping function.
In Fig. 1, underarm 5 is hinged and be installed on the subframe with turntable, and obliquity sensor 1 is fixed on the upper arm 3, and upper arm 3, underarm 5, connecting rod 2,4 of upper arm amplitude oil cylinder are all hinged, and underarm amplitude oil cylinder 6 is hinged with underarm 5, realizes functions by execution module 7.
Principle of work: obliquity sensor detects jib and the earth angle, and in Fig. 2, Fig. 3, upper arm 3 and the earth angle are less than 70 °, and the indicator lamp of obliquity sensor is green, no signal output, and Operation Van is in normal working.When obliquity sensor takes measurement of an angle when arriving 70 ° of warning angles, indicator lamp becomes redness, and execution module restriction dangerous play is also reported to the police, and this state danger of alert operator only allows the direction operation to safety afterwards, and promptly underarm rises, and upper arm falls.
By being installed in the job platform anti-tilting apparatus, making aerial platform operation in rationally safe angular range, thereby ensure operator and pedestrian's life security.
