The utility model content
The technical problems to be solved in the utility model provides a kind of belt conveyer automatic takeup, and simple in structure, control makes things convenient for, reliability is high and have the auto-tensioning power of big pulling force.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of belt conveyer automatic takeup comprises:
One belt tensioning drum,
One motor, the retarder that is connected with motor output shaft, described retarder connects a steel rope by winch drum, and described steel rope connects belt tensioning drum,
Motor rotates and passes through retarder, winch drum and steel rope realization to tension and the release of conveyer belt tensioning drum.
In a preferred embodiment of the present utility model, one tension pick-up also is set on the described steel rope, and tension pick-up sends the tension data of the steel rope that records to controller, and described controller with the tension data that obtains by analysis, relatively, send the action of instruction control motor.
In a preferred embodiment of the present utility model, described motor one side also connects a drg, when the motor dead electricity, and drg locking motor output shaft, protection tightening device.
In a preferred embodiment of the present utility model, described retarder carries latching characteristics, when belt tensioning drum is tightened up and after motor is shut down, winch drum stops operating, keeps the tension force of belt tensioning drum.
By technique scheme, the beneficial effects of the utility model are:
The utility model need not special brake equipment; and adopt a kind of retarder with auto-lock function to realize the maintenance of tension force as actuating unit; simultaneously in order to increase the reliability of whole device; the additional brake that only needs to increase by a little lock torque in retarder speed end failure-free more carries out two-fold protection to automatic takeup; this kind structure actv. has solved automatic takeup integral performance parameter quality and has been limited by brake equipment braking force size and reliability problems, has also reduced complexity and the financial cost of whole automatic takeup simultaneously.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
With reference to Fig. 1, a kind of belt conveyer automatic takeup comprises: a belt tensioning drum 1, one motor 7, and the retarder 6 that is connected with motor 7 output shafts,
Described retarder 6 connects a steel rope 2 by winch drum 4, and described steel rope 2 connects belt tensioning drum 1, motor 7 rotations and the tension and the release that realize the conveyer belt tensioning drum by retarder 6, winch drum 4 and steel rope 2.
In a preferred embodiment of the present utility model, one tension pick-up 3 also is set on the described steel rope, and tension pick-up 3 sends the tension data of the steel rope that records to controller 9, and described controller 9 with the tension data that obtains by analysis, relatively, send the action of instruction control motor 7.
In a preferred embodiment of the present utility model, described motor 7 one sides also connect a drg 8, when motor 7 dead electricity, and drg 8 locking motors 7 output shafts, protection tightening device.
In a preferred embodiment of the present utility model, described retarder 6 is band self-locking worm gear-worm reducer, when belt tensioning drum 1 is tightened up and after motor 7 is shut down, winch drum 4 stops operating, keeps the tension force of belt tensioning drum 1.Described winch drum 4 is set up on the support 5.
Principle of work of the present utility model:
The utility model is to record belt tension by the tension pick-up that is contained on the steel rope, compared according to the tension value of setting in the tension value that records and the control program by controller, determine main story, the counter-rotating or static of motor according to comparative result, by motor running condition, realize tension and release to the conveyer belt tensioning drum by band self-locking worm gear-worm reducer, cylinder, steel rope again.Thereby realize the control to conveyor belt tension.
Two shaft explosion separation motors are used for rotating band self-locking worm gear-worm reducer and cylinder as the propulsion source of tightening device, realize being entangled to of steel rope, tension belt tensioning drum, thereby tensioning load-transfer device.
Band self-locking worm gear-worm reducer is to reduce motor speed; and with the transmission of torque of motor to cylinder; play and reduce the effect that rotating speed increases torque; this worm gear-endless screw retarder of what is more important has auto-lock function; namely be tightened up and motor is shut down, winch drum stops operating that the back belt tensioning drum can't spur cylinder reverses when belt tensioning drum; this retarder has just played the effect of anti-reverse like this, makes the tension force of belt tensioning drum obtain maintenance.
Tension pick-up and tension control assembly are signal and the control part of automatic takeup, tension pick-up is used for the tension value of monitoring steel rope in real time, and in real time its signal value is reached in the controller, the value of setting in the tension value that tension control assembly records according to tension pick-up and the control program compares mutually, thereby determines main story, the counter-rotating or static of explosion separation motor.
The power hydraulic pressure drum brake mechanism is the complemental brake system of this device; it and motor are synchronized operation; also energising simultaneously of drg when being electrical power; motor can normally move under the brakeless situation; drg while dead electricity when the motor dead electricity; thereby drg is in braking mode locking motor output shaft at this moment, plays two kinds of protective effects.
Adopt the worm gear-endless screw retarder of band auto-lock function can realize that just the automatic takeup of tension force maintenance effect broken the requirement that traditional automatic takeup must the arrangement brake device, eliminated the problem of brake equipment performance restriction operatorless device technical parameter, also simplify simultaneously the integral structure of automatic takeup, saved manufacturing cost.
More than show and described groundwork of the present utility model and principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification sheets just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
