Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Examples

A cloth trolley 1 power-off interlocking protection structure is suitable for a cloth trolley 1, as shown in figure 1, a cloth belt 5 is arranged on the cloth trolley 1, the cloth trolley 1 is arranged on a track 4 of an underframe 3 and is driven to move on the track 4 by a traveling motor of the cloth trolley 1, meanwhile, the cloth belt 5 is driven to move to carry out cloth by the movement of a machine of the belt 5, on the existing cloth trolley 1, in order to avoid the over-movement of the cloth trolley 1, a mechanical limit 41 is generally arranged on the track 4, when the cloth trolley 1 moves to a limit position from side to side, a round-trip detection signal switch component 42 detects a round-trip signal and then turns around, but in the existing work, the cloth trolley 1 is not attended by a person, in the long-time cloth process, the conditions that a contracting brake is too loose and the trolley round-trip detection signal switch component 42 occurs due to the large aging and vibration amplitude of the cloth trolley 1 cause the condition that the trolley is pulled to the mechanical limit 41 by the conveying belt 5 to collide with the skipping, and at the condition that an operator supervises the trolley in time; the round trip detection signal switch component 42 can be set by using the existing formed switch, such as the following: CN210619344U, a chinese patent, discloses a remote control system for a material distribution trolley 1, which is a round-trip detection signal switch assembly 42 constructed by using a collision angle and a proximity switch 432, however, in the prior art, the round-trip detection signal switch assembly 42 only controls the movement of the material distribution trolley 1, and cannot solve the above problems.

In order to avoid the above situation, in the present embodiment, the following technical solution is adopted to solve, as shown in fig. 2-3, the apparatus further includes a power-off limit protection device 43, the power-off limit protection device 43 includes a proximity switch 432 and a relay, the proximity switch 432 is connected to the relay, the relay is connected to a power supply of the cloth trolley 1 and a power supply of the belt 5, the proximity switch 432 is disposed on the track 4 and is disposed between the mechanical limit 41 and the round trip detection signal switch component 42, and the proximity switch 432 is used for detecting the position of the cloth trolley 1; when the proximity switch 432 detects the position of the material distribution trolley 1, the relay is powered on and off to control the power supply of the material distribution trolley 1 and the power supply of the belt 5 to be directly powered off, so that the phenomenon that the trolley is pulled to the mechanical limit 41 by the conveying belt 5 to collide and jump is avoided; it should be noted that the safety of the electrical equipment can be effectively ensured by adopting the mode of driving the large power supply by the small power supply, and the economic cost is reduced.

In addition, because the embodiment is for producing cement, if the prior art is adopted, as the publication number: according to the technical scheme of the chinese patent CN210619344U, dust is large in the material distribution process, the blanking chute 2 is blocked by material flow with large viscosity in the material distribution process, and if the material flow is not cleaned in time, part of the material flows out of the blanking chute 2, so that the round-trip detection signal switch assembly 42 is accidentally contacted and stuck, and when the coverage is large enough, the round-trip detection signal switch assembly 42 is finally failed.

In order to solve the above problem, the applicant proposes the following solution in this embodiment, as shown in fig. 3, specifically, a proximity switch protection device is further provided, and the proximity switch protection device includes: the shell 431, and a screw rod 433, a sliding rod 434 and a sliding sleeve 435 which are arranged inside the shell 431; two ends of a screw rod 433 are hermetically connected to the wall of the shell 431 through bearings, the screw rod 433 is arranged in parallel with a sliding rod 434, a threaded hole and a sliding hole are formed in a sliding sleeve 435, the threaded hole is matched with the screw rod 433, and the sliding rod 434 penetrates through the sliding hole; a first end of the screw rod 433 extends out of the housing 431, a gear disc 436 is arranged at the extending end of the screw rod 433, the gear disc 436 is vertically arranged, the proximity switch 432 is arranged inside the housing 431 and close to a second end of the screw rod 433, and along the axial direction of the screw rod 433, the projections of the sliding sleeve 435 and the proximity switch 432 are overlapped; the bottom of the frame of the material distribution trolley 1 is connected with a contact plate 11 through a spring, the length of the contact plate 11 is consistent with that of the material distribution trolley 1, and the contact plate 11 slides in the vertical direction under the action of the spring; the underside of the contact plate 11 is provided with teeth which engage a gear plate 436.

By arranging the contact plate 11 and the gear disc 436, in the movement process of the distribution trolley 1, when the round-trip detection signal switch assembly 42 fails, the contact plate 11 can contact the gear disc 436 and is meshed with the gear disc 436 under the action of the spring, then the gear disc 436 is driven to rotate, the gear disc 436 drives the screw rod 433 to rotate, the screw rod 433 drives the sliding sleeve 435 to slide towards the proximity switch 432, and the proximity switch 432 are triggered; thereby cut off the power supply with

cloth dolly

1 and 5 machines on the belt, protect, avoid appearing jumping, in addition, set up through casing 431, also guaranteed that proximity switch 432 can not covered by the material, lead to the possibility of inefficacy, simultaneously, adopt the mode of contact plate 11 and toothed disc 436, even covered more material, do not influence the transmission relation yet.

Further, as shown in fig. 4, the bottom of the contact plate 11 is arc-shaped; by arranging the contact plate 11 in an arc shape, there are two advantages;

1: the lowest point of the arc shape can be guaranteed, the compression force of the spring is the largest, the friction force between the material distribution trolley 1 and the track 4 can be reduced, the phenomenon of idling is caused, and the mechanical limit 41 is realized.

2: the curved contact surface is effective to ensure that the contact plate 11 is in contact with the gear plate 436.

Moreover, with the arrangement, the shell 431 with the proximity switch 432 can be effectively arranged below the bottom frame 3, so that materials are further prevented from being adhered, and the service life is prolonged.

Finally, in the present embodiment, two sets of the proximity switch 432 and the relay are disposed and distributed on the left and right sides of the track 4, and the selection of the proximity switch 432 and the selection of the relay are also understood by those skilled in the art, so a description thereof is omitted here; it should also be emphasized that other parts of the distribution trolley 1, such as the chute 2, the power supply, etc., are prior art solutions and are not described in detail here.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
