Description

Technical Field

[0001] This utility model relates to the technical field of plate chain elevators, specifically a plate chain elevator. Background Technology

[0002] A plate chain elevator is a mechanical device used for vertically conveying various bulk materials, widely used in mining, metallurgy, building materials, chemical and other industries. Its core lies in utilizing a robust and durable chain as the power transmission medium, with carefully designed plates on the chain directly supporting and lifting the materials. The plate chain elevator conveys materials through the rotation of the chain plates and sprockets. Material is loaded onto the elevator from the feed inlet, and the elevator moves upward along an inclined channel. When it reaches the position where material needs to be unloaded, it is unloaded through the discharge port. After unloading, the elevator moves downward along the channel, ready for the next unloading. A building gypsum calcination line is a production system specifically designed for producing high-quality gypsum powder materials. Its efficient and stable operation plays a crucial role in reducing production costs, ensuring product quality, and meeting market demands. This production line mainly consists of five modules: a raw material storage and pretreatment system, a crushing and grinding system, a calcination system, a finished product storage and conveying system, and a control system. These modules work together to ensure the continuity and stability of gypsum production.

[0003] During the production of building gypsum, it needs to be lifted by a plate chain elevator. Since building gypsum is in powder form during the production stage, ordinary plate chain elevators discharge the building gypsum directly from the chain plate. There is a height difference between the feed inlet and the chain plate, and the discharge port is mostly open. Dust is easily raised during discharge, which not only pollutes the workshop environment but also endangers the health of workers. Moreover, adjusting the discharge position requires moving the entire elevator, which is very laborious. Therefore, improvements are urgently needed. Utility Model Content

[0004] The purpose of this utility model is to provide a plate chain elevator to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a plate chain elevator, comprising a supporting base plate, a supporting frame welded to the top of the supporting base plate, and an elevator body welded to the top of the supporting frame. A sprocket is installed inside the elevator body, and a chain plate is installed outside the sprocket. A reduction motor is installed on the outer wall of the top of the elevator body, and the output end of the reduction motor is fixedly connected to the sprocket. A dust cover is installed on the top of the elevator body, and a threaded telescopic guide is installed at the bottom of the dust cover. A guide rail box is welded to one side of the supporting frame below the dust cover, and a drive groove is provided inside the guide rail box. A lead screw is installed inside the drive groove. A servo motor is installed at one end of the guide rail box, and the output end of the servo motor is fixedly connected to the lead screw. A support arm is fitted around the lead screw, and a positioning clamp is provided below the threaded telescopic guide.

[0006] Preferably, the dust cover is connected to the top of the elevator body, and one end of the chain plate extends into the interior of the dust cover.

[0007] Preferably, the dust cover is a conical structure with a large upper diameter and a small lower diameter, which facilitates the connection between the dust cover and the hoist body as well as the threaded telescopic guide tube.

[0008] Preferably, a feeding pipe is installed at the bottom end of the positioning hoop, and the bottom end of the threaded telescopic guide extends into the interior of the positioning hoop and is connected to the feeding pipe.

[0009] Preferably, a diagonal brace is welded to the bottom end of the guide rail box, and one end of the diagonal brace is welded to the support frame, which improves the stability of the guide rail box.

[0010] Preferably, one end of the support arm is threadedly connected to the lead screw, and the other end of the support arm extends to the outside of the guide rail box and is equipped with an electric telescopic rod, the output end of which is fixedly connected to the positioning hoop.

[0011] Preferably, the bottom of the support base plate is equipped with eight movable wheels on both sides, which can be used to move the hoist.

[0012] Preferably, the support base plate has threaded through holes at both ends, and a threaded positioning rod is provided inside the threaded through hole. The threaded positioning rod is threadedly connected to the threaded through hole, and the bottom end of the threaded positioning rod extends to the bottom of the support base plate and is equipped with a positioning support. Rotating the threaded positioning rod causes the positioning support to move down until the positioning support contacts the ground, which increases the friction between the hoist and the ground, thereby positioning the hoist and making it more stable and reliable.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The geared motor drives the sprocket to rotate, which in turn drives the chain plate to rotate. The chain plate lifts the building gypsum powder from a low position to a high position. Since the top of the elevator body is equipped with a dust cover, the chain plate lifts the building gypsum powder to the dust cover for unloading. The dust cover reduces dust flying during unloading. Then, the building gypsum powder falls into the threaded telescopic guide tube and is discharged into the equipment inlet from the discharge pipe. The threaded telescopic guide tube fills the height difference between the discharge port and the equipment inlet. Moreover, the threaded telescopic guide tube is a closed structure, which allows the building gypsum powder to be directly introduced into the equipment during unloading, thereby reducing dust flying.

[0015] By starting the servo motor to drive the lead screw to rotate, the lead screw drives the support arm to move along the guide rail box. The support arm drives the threaded telescopic guide to move through the positioning hoop, thus adjusting the lateral position of the threaded telescopic guide. By controlling the electric telescopic rod to drive the positioning hoop to extend, the longitudinal position of the threaded telescopic guide can be adjusted, thus facilitating quick adjustment of the unloading position, saving effort and time.

A reduction motor 15 is installed on the outer wall of the top of the elevator body 3, and the output end of the reduction motor 15 is fixedly connected to the sprocket 13.

[0025] Specifically, the geared motor 15 drives the sprocket 13 to rotate, the sprocket 13 drives the chain plate 14 to rotate, and the chain plate 14 lifts the building plaster powder from a low position to a high position.

[0026] A dust cover 4 is installed on the top of the hoist body 3, and a threaded telescopic guide tube 5 is installed at the bottom of the dust cover 4. A guide rail box 6 is welded to one side of the support frame 2 below the dust cover 4. A drive groove 10 is provided inside the guide rail box 6, and a lead screw 11 is installed inside the drive groove 10. A servo motor 12 is installed at one end of the guide rail box 6. The output end of the servo motor 12 is fixedly connected to the lead screw 11. A support arm 7 is fitted on the outside of the lead screw 11. A positioning hoop 8 is provided below the threaded telescopic guide tube 5.

[0027] Since the top of the elevator body 3 is equipped with a dust cover 4, the chain plate 14 lifts the building gypsum powder to the dust cover 4 for unloading. The dust cover 4 can reduce dust flying during unloading. Then, the building gypsum powder falls into the threaded telescopic guide tube 5 and is discharged into the equipment inlet from the discharge pipe 9. The threaded telescopic guide tube 5 fills the height difference between the discharge port and the equipment inlet. Moreover, the threaded telescopic guide tube 5 is a closed structure, so the building gypsum powder can be directly introduced into the equipment during unloading, thereby reducing dust flying.

[0028] The dust cover 4 is connected to the top of the elevator body 3, and one end of the chain plate 14 extends into the interior of the dust cover 4;

[0029] Dust cover 4 has a conical structure with a large upper port diameter and a small lower port diameter;

[0032] One end of the support arm 7 is threadedly connected to the lead screw 11, and the other end of the support arm 7 extends to the outside of the guide rail box 6 and is equipped with an electric telescopic rod 701. The output end of the electric telescopic rod 701 is fixedly connected to the positioning hoop 8.

[0033] Furthermore, when it is necessary to adjust the unloading position, the servo motor 12 is started to drive the lead screw 11 to rotate. The lead screw 11 drives the support arm 7 to move along the guide rail box 6. The support arm 7 drives the threaded telescopic guide tube 5 to move through the positioning clamp 8, thereby adjusting the lateral position of the threaded telescopic guide tube 5. By controlling the electric telescopic rod 701 to drive the positioning clamp 8 to extend, the longitudinal position of the threaded telescopic guide tube 5 can be adjusted, thus facilitating quick adjustment of the unloading position, saving effort and being convenient.

The hoist can be moved by the movable wheels 16. After moving, the threaded positioning rods 18 are rotated to drive the positioning support 19 down until the positioning support 19 contacts the ground, increasing the friction between the hoist and the ground, thereby positioning the hoist and making it more stable and reliable.

[0035] In this embodiment, the following steps are taken: First, the reduction motor 15 drives the sprocket 13 to rotate, which in turn drives the chain plate 14 to rotate. The chain plate 14 lifts the building gypsum powder from a low position to a high position. Since the top of the elevator body 3 is equipped with a dust cover 4, the chain plate 14 lifts the building gypsum powder to the dust cover 4 for unloading. The dust cover 4 reduces dust flying during unloading. Then, the building gypsum powder falls into the threaded telescopic guide tube 5 and is discharged into the equipment inlet from the discharge pipe 9. The threaded telescopic guide tube 5 fills the height difference between the discharge port and the equipment inlet, and the threaded telescopic guide tube 5 is... The enclosed structure allows for direct introduction of gypsum powder into the equipment during unloading, reducing dust emissions. Furthermore, when the unloading position needs adjustment, the servo motor 12 is activated to drive the lead screw 11 to rotate. The lead screw 11 drives the support arm 7 to move along the guide rail box 6. The support arm 7, through the positioning clamp 8, drives the threaded telescopic guide tube 5 to move, thus adjusting the lateral position of the threaded telescopic guide tube 5. By controlling the electric telescopic rod 701 to drive the positioning clamp 8 to extend, the longitudinal position of the threaded telescopic guide tube 5 can be adjusted, facilitating quick and easy adjustment of the unloading position, saving effort and providing convenience.
