Abstract
The utility model discloses a computer mechanical hand for breaking rubber conveyer belts. The utility model is characterized in that a supporting frame is arranged on the both sides of a rubber belt conveyer and is provided with a hydraulic cylinder; an upper mechanical hand is arranged on the hydraulic cylinder upwards and matches an extending position on the upper part of the supporting frame; a lower mechanical hand is arranged on the hydraulic cylinder downwards and matches an extending position on the lower part of the supporting frame. An oil inlet pipe of the hydraulic device is provided with an electromagnetic valve controlled by a PLC controller, and the PLC controller provides belt breaking signals for the current of the conveyer. The utility model has the advantages of simple structure, sensitive and reliable work and good catching effect, and can catch broken belts for the second time.
Description
Technical field
The utility model belongs to the safety device of colliery travelling apron, relates in particular to the safety device of travelling apron.
Background technology
Under coal mine, in the transport systems, use travelling apron in a large number.Sometimes rupture after the adhesive tape long-time running, fracture back is because gravity and effect of inertia, adhesive tape with on material together glide rapidly, be deposited in head place, conveyer below, be difficult to cleaning, for repair brings very big difficulty, also cause casualties easily.Therefore, be sought after a kind of actv. and arrest device, the adhesive tape that will rupture is in time arrested and is prevented to glide.
40 pages of " mining safety and environmental protection " the 30th 3 phases of volume disclose a kind of belt conveyer broken belt and driving brake protection device.The critical component of this device is a setting-up eccentricity clamping mechanism on frame of conveyer, is connected a pin by a steel rope with the tensioning control setup, when broken belt pin is extracted, and eccentric wheel falls clamps adhesive tape.Though this device can play the effect of arresting, area is little owing to arresting, and causes adhesive tape to tear easily, does not still have the effect of arresting.
Summary of the invention
The purpose of this utility model provides the computer manipulator of arresting usefulness behind a kind of travelling apron of failure-free more broken belt.
Technical scheme is: bracing frame is installed in the travelling apron both sides, hydraulic actuating cylinder is installed on the bracing frame, to manipulator is housed, last manipulator leans out the position with bracing frame top and cooperates hydraulic actuating cylinder, arrests heave hand upward; Manipulator under the hydraulic actuating cylinder downward direction is installed, following manipulator leans out the position with the bracing frame bottom and cooperates, and arrests down blanking bar, on the oil inlet of hydraulic actuating cylinder electromagnetic valve is installed, electromagnetic valve is controlled by the PLC controller, and the PLC controller provides the broken belt signal by the conveyer electric current.When broken belt took place, conveyer lost load idle running, and electric current reduces suddenly, sends electric signal, and PLC controller control electromagnetic valve is opened, and gives the hydraulic actuating cylinder feed flow, and making up and down, manipulator prevents that simultaneously with the heave hand and the following blanking bar jam-packed of top broken belt from gliding.In order to make the manipulator rapid movement, available two electromagnetic valve twin flues are simultaneously to the hydraulic actuating cylinder feed flow.
Can control the eccentric clamping mechanism of existing brake protection device simultaneously by the PLC controller.Technical scheme is that electromagnetic lock is installed on eccentric wheel, removes existing steel rope and tensioning control setup.Just often, electromagnetic lock pins eccentric block, and the PLC controller is controlled the unlatching of electromagnetic lock simultaneously during broken belt, and eccentric block is fallen simultaneously, clamps broken belt.
By the PLC controller automatically controlled part of may command conveyer also, sideslip, parking, the excess current of conveyer, low voltage, the runaway accident of adhesive tape are controlled.
Good effect of the present utility model is, 1, adopt hydraulic actuating cylinder to two end motions, drive the manipulator of both direction, and can clamp top heave hand and below blanking bar behind the broken belt simultaneously, no matter the broken belt position occurs in Anywhere, can both arrest effectively; And manipulator to clamp area big, prevent that effectively broken belt from tearing.2, adopt PLC controller modulated pressure cylinder, simple in structure, work is sensitive reliable.But 3, the also control of the present eccentric clamping mechanism of double as of PLC controller is more effective than steel rope mechanical control by rising and falling of electromagnetic lock control eccentric, and is sensitive reliable.On the basis of original eccentric clamping mechanism, add the application's device, can realize the secondary of broken belt is arrested, make that to arrest effect more reliable.But 4, the PLC controller safe electric control of double as conveyer also improves electric control function.
Description of drawings
Fig. 1 is the lateral plan scheme drawing that embodiment arrests device, and Fig. 2 is that secondary is arrested device front view scheme drawing when using.
Marginal data: 1 one tops lean out the position, the last manipulator of 2-, and the 3-bracing frame, the 4-hydraulic actuating cylinder, manipulator under the 5-, the 6-bottom leans out the position, 7-following blanking bar, 8-electromagnetic valve, the last heave hand of 9-, 10-PLC controller, 11-electromagnetic lock, 12-eccentric block.
The specific embodiment
With reference to Fig. 1 Fig. 2, in the travelling apron both sides bracing frame 3 is installed, the top of bracing frame 3 leans out position 1 and leans out heave hand 9 upsides, and the bottom leans out position 6 and leans out down blanking bar 7 downsides; Install hydraulic actuating cylinder 4 on the bracing frame 3, last manipulator 2 is arranged at hydraulic actuating cylinder 4 tops, and last manipulator 2 and bracing frame 3 tops lean out position 1 and cooperate and can clamp heave hand 9; Following manipulator 5 is arranged at hydraulic actuating cylinder 4 bottoms, and following manipulator 5 and bracing frame 3 bottoms lean out position 6 and cooperate and can clamp down blanking bar 7; Electromagnetic valve 8 is installed on the feed tube of hydraulic actuating cylinder 4, and electromagnetic valve 8 is by being controlled by PLC controller 10.
In Fig. 2, also comprise eccentric clamping mechanism, eccentric block 12 and electromagnetic lock 11 are arranged on the eccentric clamping mechanism, the unlatching of PLC controller 10 control electromagnetic locks 11, electromagnetic lock 11 is controlled rising and falling of eccentric blocks 12.
