Abstract
The utility model discloses a spring energy-storage broken-belt grasping device for an adhesive belt conveyer, which comprises a grasping device composed of an upper group of grasping paws and a lower two group of grasping paws, a spring storing potential energy, a chain wheel for connecting the upper and the lower grasping paws and making the grasping paws interlinked, a chain, sensors, a program controller and an electromagnetic switch. When the adhesive belt of the adhesive belt conveyer with a big inclination angle is locally stretched to form the broken belt after cracks, the sensor transmits the grasping signal obtained by picking the pulse signal of the broken belt reverse motion to be discriminated and processed by the program controller to the electromagnetic switch, and three groups of grasping paws are simultaneously moved under the action of the potential energy of the spring; the adhesive belt is compressed between a carrier roller and a cross beam, and the eccentric circular arc cylindrical surface of the grasping paw has self-tightening action. The device is provided with the sensors in a multipoint mode; the broken belt is discovered instantly, the grasp is timely and firm without damaging the adhesive belt, and a plurality of paws are interlinked. When a conveying belt normally runs, the grasping paw is kept away from the adhesive belt without causing the blockage and the overflow of cargoes.
Description
Technical field
The utility model relates to a kind of travelling apron technical field, relates in particular to high spud angle travelling apron belt break protection device.
Background technology
Major part is not installed belt break protection device on the travelling apron at present, normally checks adhesive tape by the workman, periodic replacement.Because the mine operation environment is sternly bad, it is very inconvenient overhaul, and the fed distance of travelling apron is long, especially when high spud angle is carried, in case unexpected broken belt makes the adhesive tape cunning of stopping as not arresting moment in the course of conveying, will bring injury to the equipment and the person.
The present broken belt catching device that uses, all be after broken belt takes place, to remove to brake adhesive tape again, it is long to arrest delay time, cause the accident, if will trigger the gap turns down, arrest device and adhesive tape and press close to not only to injure easily adhesive tape, when the goods on the adhesive tape is too much, will cause and arrest device retaining and cut or overflow phenomena occurs.Present broken belt brake equipment value of establishing produces the frictionally damage adhesive tape in the adhesive tape both sides of the edge when rubber belt from deviating.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of adhesive tape and promptly is found in the moment of rupturing, and is swift in response, and arrests the failure-free broken belt and arrests device.
In order to solve the problems of the technologies described above, the utility model is achieved by the following technical solution: a kind of travelling apron spring energy-storage broken belt is arrested device, it is characterized in that: the catching device assembly is installed on the adhesive tape support of travelling apron top; Many sensors be installed in respectively on the support of multiple spot position of conveyer and with last adhesive tape both sides along contacting; Connect by signal wire (SW) between the electromagnetic switch on program controller and power switch, sensor and the catching device assembly.
Arrest the pawl symmetry on described two pairs and be installed in adhesive tape top, and be fixed on the two ends of axle; The bottom of last adhesive tape with on arrest the pawl opposite position near on adhesive tape two pairs of carrying rollers are installed, the carrying roller two ends are connected with the carrier roller frame sliding fit, carrier roller frame is fixed on the crossbeam; Be equipped with arrest pawl go up the axle two ends by bearing installation on support; Under the installation of the bottom of following adhesive tape, arrest pawl, arrest the middle part that pawl is fixed on lower shaft down; The lower shaft two ends are connected with support by bearing; The left end of upper and lower axle is installed sprocket wheel and lower sprocket respectively, and two sprocket wheels connect by chain; Chain one end is around the lower sprocket half cycle and fix on it, and the chain other end is walked around upper sprocket wheel and is connected with an end of spring, and the other end of spring is connected with spring perch on being fixed on adhesive tape support; The coaxial fixed ratchet wheel in the outer end of upper sprocket wheel is installed ratchet with the position that the ratchet cylindrical is tangent, and an end of ratchet is fixed on the pawl base, and the other end links to each other with the pull bar of electromagnetic switch, and pawl base and electromagnetic switch are separately fixed on the adhesive tape support; The end face of ratchet is installed the return handle.
Described sensor is a speed detector.
During described conveyer normal working, the position of ratchet restriction and ratchet keeps certain distance with upper and lower adhesive tape respectively with the joining upper and lower pawl of arresting of ratchet.
Good effect of the present invention is: multiple spot is provided with the broken belt sensor, adhesive tape produces the generation local elongation in fracture, breach causes velocity variations just to be found and in time to arrest, broken belt can not cause the accident, and arrests the pawl interlock for two groups up and down, arrests the effective adhesive tape that do not damage again.Arresting pawl rotational angle when not using, to depart from adhesive tape far away, can not contact goods and form retaining and cut or overflow, also can not touch during rubber belt from deviating and arrest pawl.
Description of drawings
The explanation and the specific embodiment are described in further detail the utility model below with reference to accompanying drawings
Fig. 1 is the structural representation that the utility model is arrested device.
Fig. 2 is the A-A section-drawing of Fig. 1.
Fig. 3 arrests control principle figure.
Among the figure: 1, adhesive tape support, 2, lower shaft, 3, arrest pawl down, 4, lower sprocket, 5, chain, 6, following adhesive tape, 7, crossbeam, 8, crossbeam, 9, roller rack, 10, carrying roller, 11, upper sprocket wheel, 12, go up axle, 13, on arrest pawl, 14, go up adhesive tape, 15, spring perch, 16, pawl base, 17, ratchet, 18, ratchet 19, electromagnetic switch, 20, spring, 21, the return handle, 22, sensor, 23, program controller, 24, signal wire (SW), 25, power switch, 26, the catching device assembly.
The specific embodiment
Shown in Figure 3, multiple spot sensor installation 22 on adhesive tape on the travelling apron 14, the impulse singla of the cracking generation local velocity variation because adhesive tape stretches that sensor 22 picks up the adhesive tape fracture location is sent to program controller 23 by signal wire (SW) again, these signals are transferred to power switch 25 and electromagnetic switch 19 through the broken belt signal that PLC program controller differentiated treatment obtains respectively by signal wire (SW) 24, power switch 25 quits work driving force motor, the ratchet 18 of electromagnetic switch 19 pull bars pulling simultaneously makes it to break away from ratchet 17, ratchet 17 is under the pulling force of spring potential energy, rotate to an angle through the chain pulling, at last lower sprocket 11,4 and the effect of chain 5 go up lower shaft 12 down, 2 rotate an angle synchronously, arrest pawl 13 up and down to making, 3 rotate an angle thereupon is adjacent to adhesive tape 14 up and down respectively, 6, because arresting pawl is the eccentric cylinder cambered surface, arresting the moment broken belt downslide that pawl contacts with adhesive tape, the adhesive tape pulling is arrested the pawl rotation up and down adhesive tape is pressed on carrying roller 10 and the crossbeam 7, and function of self-tightening is arranged, realize that adhesive tape stopped gliding in the moment of broken belt.
The direction of arrow A is the moving line direction of adhesive tape behind the broken belt among Fig. 2, before the work of adhesive tape conveyer, hold return handle 21 anticlockwise motion ratchets 17, when arresting after pawl 13,3 leaves the adhesive tape certain distance, (among Fig. 2 shown in the long and two-short dash line) blocks ratchet 17 with ratchet 18, at this moment, spring 20 is subjected to elongate deposit potential energy.
