The embodiment of the utility model provides a novel high-efficiency and safe plug chain conveying drive device, comprising a gear reducer 1, a main plug disc 5 is mounted on the shaft of the gear reducer 1, and a plug chain 6 is meshed on the main plug disc 5;

[0026] The gear reducer 1 is provided with a maintenance port 2, in which an opening structure 4 is installed, and the opening structure 4 includes a cover plate 401, a pin shaft 402, a first ring 403, a second ring 404, a tension spring 405, a transverse groove 406, a block 407 and a slot 408;

[0027] The cover plate 401 is installed in the maintenance port 2 through the pin shaft 402, the first ring 403 is installed on the cover plate 401, the second ring 404 is installed in the gear reducer 1, the two sides of the tension spring 405 are respectively hung on the first ring 403 and the second ring 404, the transverse groove 406 is opened on the cover plate 401, the clamping block 407 is installed in the transverse groove 406 through the slide rail, the slot 408 is opened in the maintenance port 2, and the clamping block 407 is inserted into the slot 408;

[0028] A displacement sensor 9 is embedded in the cover plate 401 .

[0029] It should be noted that, in this embodiment, the model of the gear reducer 1 is GPLF60-180, and its power on and off is controlled by an external controller. Advanced gear reducers are selected and hard tooth surface transmission technology is adopted, which can effectively reduce the friction between gears and thus improve efficiency; it has strong carrying capacity and can adapt to high-load working conditions, and its service life is increased from about 3000 hours to about 10000 hours. The power of the reducer with the same power is increased by about 30%, and the slide rail is a damping slide rail. The model of the displacement sensor 9 is BRT. The displacement sensor 9 is electrically connected to the controller of the gear reducer 1 through built-in wires. The displacement sensor 9 is a type of device used to measure the change in the position of an object. Its working principle is based on different physical phenomena and effects. The sensor can detect displacement by means of resistance, capacitance, inductance, optics, etc.

[0030] Specifically, when in use, the gear reducer 1 drives the main plug disc 5 to rotate, thereby transmitting the plug chain 6 and completing the corresponding work. When the internal gear of the gear reducer 1 needs to be repaired, the card block 407 is moved outward, and the card block 407 moves in the horizontal groove 406 through the slide rail. At this time, the card block 407 leaves the slot 408, so that the cover plate 401 rotates on the maintenance port 2 through the pin shaft 402, so that the maintenance port 2 is opened. At this time, the tension spring 405 is stretched, and the displacement sensor 9 detects that the cover plate 401 is opened, then the external controller cuts off the power to the gear reducer 1 and stops working, so that the staff can operate conveniently during the assembly and maintenance process.

[0031] As a preferred specific embodiment, an arc groove 3 is opened outside the gear reducer 1, a bearing 10 is installed in the arc groove 3, a secondary plug disc 7 is installed in the inner ring of the bearing 10, and a plug chain 6 is meshedly connected to the secondary plug disc 7;

[0032] The bearing 10 is placed in the arc groove 3, and the bearing 10 is limited in the arc groove 3 by a sliding structure 15. There are two sliding structures 15, and the sliding structures 15 are symmetrically distributed on both sides with the center line of the bearing 10 as the center.

[0033] The sliding structure 15 includes a slider 16 and a slide groove 17. The slider 16 is mounted on the bearing 10. The slide groove 17 is provided in the arc groove 3. The slider 16 is slidably engaged in the slide groove 17.

[0034] A convex block 11 is installed on the bearing 10 , a control switch 12 is installed in the arc groove 3 , a spring 13 is installed between the convex block 11 and the control switch 12 , a push rod 14 is installed on the convex block 11 , and the push rod 14 is placed in the spring 13 .

[0035] It should be noted that, in this embodiment, the surface of the arc groove 3 opened by the slide groove 17 is a vertical surface, and the shaft of the auxiliary plug disc 7 is installed in the inner ring of the bearing 10, and the control switch 12 is electrically connected to the power supply circuit of the gear reducer 1. The model of the control switch 12 is XB2. The control switch 12 is the second controller of the gear reducer 1. When the control switch 12 is closed, the gear reducer 1 works in one step.

[0036] Specifically, when in use, turn on the control switch 12 to press down the auxiliary plug disc 7, then the bearing 10 slides downward in the slide groove 17 through the slider 16, and the bearing 10 moves downward to the lowest position in the arc groove 3. At this time, the auxiliary plug disc 7 is horizontal with the main plug disc 5, and the spring 13 is in a stretched state, and the plug chain 6 is engaged with the auxiliary plug disc 7 for transmission. When the chain breaks, the plug chain 6 disengages from the auxiliary plug disc 7, the spring 13 contracts, and the bearing 10 moves up, so that the push rod 14 on the protrusion 11 moves up, and the control switch 12 is closed. At this time, the gear reducer 1 stops working and the machine stops.

[0037] As a preferred embodiment, a horizontal block 8 is installed on the clamping block 407, and the surface of the horizontal block 8 is processed with anti-slip patterns;

[0038] The gear reducer 1 is provided with four mounting holes, which are distributed at four corners of the gear reducer 1 .

[0039] It should be noted that, in this embodiment, the horizontal block 8 facilitates the movement of the block 407, and the anti-slip pattern on the surface of the horizontal block 8 increases the friction between the fingers and the horizontal block 8 to prevent the fingers from slipping out of the hands. The gear reducer 1 can be fixed at a designated working position through the mounting hole.

[0040] Specifically, when in use, the horizontal block 8 is moved by fingers to drive the clamping block 407 to move, which facilitates the adjustment and movement of the clamping block 407, and the external bolts pass through the mounting holes on the gear reducer 1, which can facilitate the gear reducer 1 to be installed at a designated location at work.

[0041] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

[0042] The working process and working principle of the utility model are as follows: when in use, an advanced gear reducer 1 is selected, and hard tooth surface transmission technology is adopted, which can effectively reduce the friction between gears, thereby improving efficiency; it has strong bearing capacity and can adapt to high-load working conditions, so that the plug chain 6 is respectively engaged with the main plug disc 5 and the auxiliary plug disc 7, and the external controller controls the gear reducer 1 to work, and at the same time turns on the control switch 12, the gear reducer 1 drives the main plug disc 5 to rotate, so that the plug chain 6 is transmitted and the corresponding work is completed. When the internal gear of the gear reducer 1 needs to be repaired, the card block 407 is moved outward, and the card block 407 is moved in the direction of the slide rail. The cover 401 is rotated on the maintenance port 2 through the pin 402, and the maintenance port 2 is opened. At this time, the tension spring 405 is stretched, and the displacement sensor 9 detects that the cover 401 is opened, then the external controller cuts off the power to the gear reducer 1 and stops working, so that it is convenient for the staff to operate during assembly and maintenance. However, when the chain breaks, the plug chain 6 is separated from the auxiliary plug disc 7, the spring 13 contracts, and the bearing 10 moves up, so that the push rod 14 on the protrusion 11 moves up, and the control switch 12 is turned off. At this time, the gear reducer 1 stops working and the machine stops.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
