Description

[Technical field]

[0001] The utility model relates to the field of solid material transportation, in particular to a novel chain-off transmission alarm mechanism for a tube chain conveyor. [Background Technology]

[0002] Currently, in typical chemical raw material conveying systems, the sprocket box of a tube chain conveyor requires a chain-off alarm device. When a chain becomes uncoupled, a disc-mounted drive rod rotates a sensor contact on the outside of the box. This rotation sends a signal to the DCS control system, triggering an alarm. However, existing transmission mechanisms often misalign the drive rod and sensor contact, resulting in missed or false alarms. Therefore, a novel chain-off alarm mechanism for tube chain conveyors would be extremely valuable. [Utility Model Content]

[0003] The purpose of the present utility model is to solve the above-mentioned deficiencies and provide a new chain-off transmission alarm mechanism for a tube chain conveyor, which increases friction by clamping the shaft surface with packing, and when the clamping force decreases, increases the friction of the packing by quickly locking the fasteners, thereby achieving synchronous rotation of the transmission rod and the sensor contact, avoiding missed alarms and false alarms.

[0004] In order to achieve the above-mentioned purpose, a new type of off-chain transmission alarm mechanism for a tube chain conveyor is designed, including a packing seat 1, a packing gland 2, a fastener 3, a transmission shaft 5, a sensor contact 6, a box wall 7, a transmission rod shaft 9 and a packing 10. The packing seat 1 is fixedly connected to the box wall 7 by welding, and the packing 10 is installed in the packing seat 1. The packing 10 is sleeved on the transmission shaft 5, one end of the transmission shaft 5 is fixedly connected to the transmission rod shaft 9, and the other end of the transmission shaft 5 is fixedly connected to the sensor contact 6. One side of the packing 10 is connected to the box wall 7, and the other side of the packing 10 is provided with a packing gland 2, and is pressed by the packing gland 2. The packing gland 2 is locked and fixed to the packing seat 1 by the fastener 3.

[0005] Furthermore, one end of the transmission shaft 5 extends into the transmission rod shaft 9, and the transmission shaft 5 and the transmission rod shaft 9 are locked and fixed by a nut 8, thereby further ensuring that when the transmission rod shaft 9 rotates, the sensor contact 6 on the transmission shaft 5 is driven to rotate accordingly.

[0006] Furthermore, a mounting hole is provided on the top of the sensing contact 6, and the sensing contact 6 is passed through the mounting hole on the transmission shaft 5. Nuts 4 are provided on both sides of the sensing contact 6, and the sensing contact 6 is locked and fixed on the transmission shaft 5 by nuts 4, thereby making the installation position of the sensing contact 6 more flexible and the installation more stable.

[0007] Furthermore, the bottom of the sensing contact 6 is bent to form an L-shaped structure, and its width gradually decreases from the top to the bottom, thereby further ensuring that the triggering effect of the sensing contact 6 is stronger.

[0008] Furthermore, the packing gland 2 is in the shape of a stepped shaft, the small diameter section of the packing gland 2 is pressed on the outside of the packing 10, and the large diameter section of the packing gland 2 is locked and fixed to the packing seat 1 by the fastener 3. The structure is more compact and the installation is also very convenient.

[0009] Furthermore, the packing 10 is compressed by the packing gland 2 and expands, and the inner surface of the packing 10 clamps the transmission shaft 5 .

[0010] Furthermore, after the fastener 3 is locked, the packing 10 clamps the transmission shaft 5, and when the transmission rod shaft 9 rotates, the sensor contact 6 is driven to rotate accordingly.

[0011] Compared with the prior art, the present invention has a novel and simple structure and a reasonable design. The friction force is increased by using the packing to clamp the shaft surface. When the clamping force is reduced, the friction force of the packing can be increased by quickly locking the fasteners, so that the transmission rod and the sensor contact can rotate synchronously, thereby preventing missed alarms or false alarms. In addition, the present invention can realize quick locking of the packing and quick replacement of the seal. At the same time, the present invention can realize more flexible installation position, and is worthy of popularization and application. [Brief Description of the Drawings]

[0015] As attached Figure 1 and attached Figure 2As shown, the utility model relates to the field of solid material conveying, specifically, a new type of off-chain transmission alarm mechanism for a pipe chain conveyor for a conveying device that pushes materials to move in a pipe through a non-metallic circular plate. The new type of off-chain transmission alarm mechanism for a pipe chain conveyor comprises a packing seat 1, a packing gland 2, a fastener 3, a nut 1 4, a transmission shaft 5, a sensor contact 6, a box wall 7, a nut 2 8, a transmission rod shaft 9, and a packing 10. The packing seat 1 is fixedly connected to the box wall 7 by welding. The packing 10 is installed in the packing seat 1 and is sleeved on the transmission shaft 5. One end of the transmission shaft 5 is fixedly connected to the transmission rod shaft 9, and the other end of the transmission shaft 5 is fixedly connected to the sensor contact 6. One side of the packing 10 is connected to the box wall 7. The other side of the packing 10 is provided with a packing gland 2 and is pressed by the packing gland 2. The packing gland 2 is locked and fixed to the packing seat 1 by the fastener 3.

[0016] One end of the transmission shaft 5 extends into the transmission rod shaft 9, and the transmission shaft 5 and the transmission rod shaft 9 are locked and fixed by a nut 2 8, further ensuring that when the transmission rod shaft 9 rotates, the sensor contact 6 on the transmission shaft 5 rotates accordingly. The sensor contact 6 has a mounting hole at the top and is inserted into the transmission shaft 5 through the mounting hole. Nuts 1 4 are provided on both sides of the sensor contact 6 and are locked and fixed to the transmission shaft 5 by nuts 1 4, making the installation position of the sensor contact 6 more flexible and the installation more stable. The bottom of the sensor contact 6 is bent into an L-shaped structure, and its width gradually decreases from top to bottom, further ensuring that the triggering effect of the sensor contact 6 is more precise.

[0017] The packing gland 2 is a stepped shaft. The smaller diameter section of the gland 2 presses against the outer surface of the packing 10, while the larger diameter section is secured to the packing seat 1 via fasteners 3. This creates a more compact structure and facilitates installation. The packing 10 expands after being compressed by the gland 2, and its inner surface clamps the drive shaft 5. Once the fasteners 3 are tightened, the packing 10 clamps the drive shaft 5, and when the drive shaft 9 rotates, the sensor contact 6 rotates with it.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0019] The utility model mainly comprises filler seat 1, filler gland 2, fastener 3, nut one 4, transmission shaft 5, sensing contact 6, box wall 7, nut two 8, transmission lever shaft 9, packing 10 are constituteed. Transmission shaft 5 and transmission lever shaft 9 are connected, and filler seat 1 is fixed through welding with box wall 7, packing 10 is loaded into filler seat 1, and sensing contact 6 is on transmission shaft 5. Specifically, transmission shaft 5 and transmission lever shaft 9 are locked through nut two 8;Packing 10 is pressed by filler gland 2, and fastener 3 is locked;Sensing contact 6 is locked through two nut one 4;Packing 10 is inflated after being pressed by filler gland 2, and transmission shaft 5 is clamped on the surface;Transmission shaft 5 cannot rotate after fastener 3 is locked;When transmission lever shaft 9 rotates, sensing contact 6 rotates along with it.

[0020] The working principle of the utility model is as follows: the surface of the packing clamp shaft is used to increase the friction force, and when the clamping force decreases, the friction force of the packing can be increased by quickly locking the fastener, so that the transmission lever and the sensing contact rotate synchronously, and false alarm and false alarm are avoided.

[0021] Compared with the prior art, the utility model can realize synchronous rotation of the transmission lever and the sensing contact, realize that false alarm does not occur, realize that false alarm does not occur, realize that the packing is quickly locked, realize that the sealing element is quickly replaced, and realize that the installation position is more flexible.
