Abstract
The utility model discloses a spiral tensioning device for a belt-type conveyor which comprises a sliding bracket, a nut, a screw, a drive device, a speed sensor and a control circuit, wherein the sliding bracket is used for fixing a bearing seat at two ends of a tension rolling barrel; the sliding bracket is movably built on a tail bracket of the conveyor and the sliding bracket is fixed with a nut; the screw matches with the nut on the sliding bracket and is rotably fixed on the tail bracket; the drive device drives the screw to rotate; the speed sensor detects rotating speed of the tension rolling barrel; the control circuit controls the drive device to rotate clockwise or anticlockwise according to electric signals of the speed sensor. Due to the speed sensor of the tension rolling barrel and the corresponding control circuit, stretching force of a conveyor belt is automatically adjusted, work intensity of workers is reduced and service life of the conveyor belt is prolonged.
Description
Technical field
The utility model relates to the belt of belt conveyor tightening device, specifically is used for the spiral tensioning device of belt conveyer.
Background technology
At present, use the conveyer apron spiral take-up device above the conveyer, its structure is introduced such as " belt conveyor slack adjuster and select " literary composition of " coal technology " the 28th volume the 7th phase 3-5 page or leaf publication: tension drum two end axles bearing is installed on the balladeur train with nut, and balladeur train can be mobile at tailstock.When (passing through handwheel) rotates screw rod on the tailstock, nut on the balladeur train is advanced together with balladeur train or retreat, the purpose that reaches tension or loosen is to regulate the tension force of load-transfer device.Because the relaxed state of load-transfer device needs regular hand inspection, and need the tail end handwheel of artificial rotary screw to regulate, thereby need personnel on duty.If on-the-spot in time the discovery load-transfer device is not lax, and the load-transfer device relaxation cases has occured during on-the-spot left unguarded, cause load-transfer device and belt pulley to produce skidding, material on the conveyer just can't be carried, the material that causes upstream conveyor to be carried getting off constantly is deposited on the conveyer, can produce the conveyer deflector chute and partly fill in material, flash, imponderable industrial accident phenomenon seriously more likely occurs in a series of bad phenomenon such as upstream conveyor hopper blocking.Simultaneously spiral tensioning device is as being in for a long time the maximum tension situation, the life-span that can reduce load-transfer device, and cause frequent shutdown to change load-transfer device, increased productive costs.
Summary of the invention
The purpose of this utility model provides a kind of spiral tensioning device for belt conveyer, can realize unmanned field control, and automatically detects between load-transfer device and the tension drum whether skid the device of realization auto-tensioning.
The utility model is achieved in that the balladeur train that comprises fixed strain cylinder two end axles bearing, and balladeur train is erected on the conveyer tailstock movably, is fixed with nut on the balladeur train; The screw rod that cooperates with nut on the balladeur train, screw rod is rotatably mounted on the tailstock; The actuating device of drive screw rotation; One is arranged on the speed sensor that is used for detecting the tension drum velocity of rotation on the balladeur train; And the electric signal accessory drive according to speed sensor is just being done or the control circuit of contrarotation.
When load-transfer device and tension drum generation skidding, be that the load-transfer device slackness becomes greatly, tensile force is inadequate, at this moment, the tension drum rotating speed increases, and when speed reached setting value, speed sensor arrived control circuit with the electric signal transmission that records, start actuating device and just doing or contrarotation, balladeur train moves and Conveyer Belt so that screw rod drives by nut; Simultaneously, the tension drum rotating speed lowers, and when its rotating speed eased down to setting value, speed sensor arrived control circuit with the electric signal transmission that records, and actuating device is shut down.Otherwise when tension drum Speed Reduction during to setting value, speed sensor to control circuit, starts the electric signal transmission that records actuating device and does anti-or be rotated in the forward, and moves and loosens load-transfer device so that screw rod drives balladeur train by nut; Simultaneously, the tension drum rotating speed increases, and when its rotating speed was increased to setting value, speed sensor arrived control circuit with the electric signal transmission that records, and actuating device is shut down.Thereby realize automatically regulating the purpose of belt tension.
Described actuating device is reducing motor.
As shown from the above technical solution, the utility model arranges tension drum speed sensor and corresponding control circuit by balladeur train, can realize automatically regulating the tension force of load-transfer device, does not need staff on duty, not only reduce intensity of workers, also improved the service life of conveyer; And simple in structure, be easy to realize automatic control.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is that Fig. 1 is along A-A line cutaway view;
Fig. 3 is that Fig. 2 is along B-B line cutaway view;
The specific embodiment
As shown in Figure 1 to Figure 3, comprise tailstock 1 and two balladeur trains 2 that are symmetricly set on tension drum 5 two ends, tension drum 5 two end axles bearings 51 are fixed on the balladeur train 2.
The balladeur train cross section is inverted U-shaped and is sleeved on the tailstock 1, be fixed with the slide block 21 that cooperates with tailstock 1 upper surface in the balladeur train 2, bottom, balladeur train 2 two ends has by bolt 23 fixed cross beams 22, crossbeam 22 is fixed on the balladeur train 21 by bolt 23, crossbeam 22 tops are fixed with nut hold down groove 24, square nut 3 is installed in the nut hold down groove 24, screw rod 4 and nut 3 are with screw thread fit, screw rod 4 afterbodys have the radially spacing clamping plate of pair screw rod 4 11, clamping plate 11 are fixed on the tailstock 1 by bolt 12, so that screw rod 4 is rotatably mounted on the tailstock 1.
The engine installation of drive screw 4 is reducing motor 6, and reducing motor 5 is fixed on the tailstock 1 by support 13.
Right side balladeur train and tensioner mechanism part thereof have been omitted among Fig. 2.The tensioner mechanism of the tensioner mechanism of right side balladeur train part and the left sideslip frame of Fig. 2 partly is and is symmetrical arranged, and comprises nut, screw rod and reducing motor thereof etc.
The speed sensor 7 that detects tension drum 5 velocities of rotation is fixed on the balladeur train 2 by support 25.
When relaxed condition occurs in load-transfer device 8, the friction force of tension drum 5 and load-transfer device 8 reduces, tension drum 5 skids with load-transfer device 8, tension drum 5 rotating speeds increase, when speed reaches setting value, speed sensor 7 arrives control circuit with the electric signal transmission that records, and starts reducing motor 6 and is just doing or contrarotation, and balladeur trains 2 move to Fig. 1 right side and Conveyer Belt 8 so that screw rod 4 drives by nut 3; Simultaneously, tension drum 5 rotating speeds lower, and when its rotating speed eased down to setting value, speed sensor 7 arrived control circuit with the electric signal transmission that records, and reducing motor 6 is shut down.Otherwise when tension drum 5 Speed Reductions during to setting value, speed sensor 7 to control circuit, starts the electric signal transmission that records reducing motor 6 and does anti-or be rotated in the forward, so that screw rod 4 drives balladeur trains 2 by nut 3 is mobile and loosen load-transfer device 8 to Fig. 1 left side; Simultaneously, tension drum 5 rotating speeds increase, and when its rotating speed was increased to setting value, speed sensor 7 arrived control circuit with the electric signal transmission that records, and reducing motor 6 is shut down.Thereby realize automatically regulating the tension force of load-transfer device.
