Description

Technical Field

[0001] The present application relates to the field of valve flap grinding technology, and in particular to a one-step formed valve flap grinding device. Background Art

[0002] In the electric power, chemical, petroleum, steel, metallurgy, papermaking and other industries, it is often necessary to repair and maintain the safety valves in the pipeline system. After long-term use, the sealing surface on the valve disc is prone to rust and corrosion. Therefore, during the repair and maintenance of the valve, it is often necessary to remove the valve disc in the valve body and grind the sealing surface.

[0003] In the prior art, a one-time formed valve disc grinder is often used to grind the valve disc. The valve disc grinder mainly includes a frame, on which a grinding disc is connected through a motor, a coupling, a reducer, etc., a plurality of valve disc retaining rings are placed in the grinding disc, and a plurality of baffles are installed on the side wall of the grinding disc, and the side wall of the baffle is against the valve disc retaining ring. When grinding the sealing surface of the valve disc, the operator needs to manually spread the grinding sand evenly on the grinding disc, and then place the valve disc retaining ring on the grinding disc, and place the valve disc sealing surface to be ground on the grinding sand in the valve disc retaining ring. The operator starts the motor, and the motor drives the grinding disc to rotate. During the rotation of the grinding disc, the valve disc rotates, and the grinding of the sealing surface can be completed.

[0004] In the actual production and processing process, the inventors found that when the operator lays the abrasive sand on the grinding disc, he needs to weigh the required weight of the abrasive sand in advance using an electronic scale or the like according to the required thickness of the abrasive sand. The process of weighing the abrasive sand is rather cumbersome and there is room for improvement. Utility Model Content

[0005] In order to improve the convenience for operators to use the grinding device, the present application provides a one-time formed valve flap grinding device.

[0006] The one-step forming valve disc grinding device provided in the present application adopts the following technical solution:

[0007] A one-step valve disc grinding device comprises a frame, a feeding bracket is rotatably connected to the frame, a feeding hopper is detachably mounted on the feeding bracket, a discharge channel is connected to the bottom of the feeding hopper, and the discharge channel is mounted above the grinding disc; and:

[0008] A control panel, fixedly mounted on the frame, for inputting a set weight signal and a start signal;

[0009] A discharging mechanism, installed in the feeding hopper and connected to the signal output terminal of the control panel, for receiving the start signal and driving the abrasive sand in the hopper to flow out through the discharging channel;

[0010] A discharge control module is installed on the feeding bracket and is connected to the signal input terminal of the control panel, and is used to receive the start signal and detect the discharge amount of the grinding sand, and output a control signal when the discharge amount of the grinding sand reaches a set weight;

[0011] A buzzer, fixedly mounted on the feeding bracket, connected to the signal output terminal of the discharging control module, for receiving the control signal and issuing a warning sound;

[0012] The signal input end of the discharging mechanism is signal-connected to the signal input end of the discharging control module, and the discharging mechanism receives the control signal and stops discharging.

[0013] By adopting the above technical solution, before using the valve disc grinder, the operator can first rotate the feeding bracket on the frame to the discharge channel of the feeding hopper located above the grinding disc. After the operator pours the grinding sand into the feeding hopper, the operator can set the required grinding sand weight through the control panel and input the start signal; after receiving the start signal, the discharging mechanism drives the grinding sand in the feeding hopper to be transported to the surface of the grinding disc through the discharging channel; in the process of the discharging mechanism outputting the grinding sand, the discharging control module detects the amount of grinding sand discharged in real time, and controls the discharging mechanism to stop feeding when the amount of grinding sand discharged reaches the set weight, and controls the sound and light alarm to emit a warning sound. Through the mutual coordination and use of the control panel, the discharging mechanism, the discharging control module, and the buzzer, the technical effect of automatic and quantitative feeding of grinding sand can be achieved, eliminating the operator's manual weighing and feeding process of the abrasive paste. When the amount of grinding sand fed reaches the set weight, the operator can know that the feeding of grinding sand is completed through the prompt sound of the buzzer, which can further improve the convenience of the operator in using the grinding device. In addition, since the feeding bracket is rotatably installed on the frame, when the operator finishes feeding, the feeding bracket can be rotated away from the top of the grinding disc, which is convenient for the operator to spread the grinding sand, place the valve disc and other operations.

[0015] The driving end of the servo motor is fixedly connected to the auger, and the auger extends into the discharge channel.

[0016] By adopting the above technical solution, during the process of feeding the abrasive sand, the servo motor drives the auger to rotate at a constant speed, so that the abrasive sand in the feeding hopper flows out along the spiral blades of the auger, thereby achieving the technical effect of automatically feeding the abrasive sand.

[0017] Preferably, the feeding bracket includes a second mounting plate, the second mounting plate is located below the first mounting plate, and an extension portion is provided on the top of the feeding hopper extending outward, and the extension portion is located on the second mounting plate;

[0022] By adopting the above technical solution, during the process of adding abrasive sand, the weighing sensor detects the weight of the abrasive sand in the feeding hopper in real time. The first single-chip microcomputer compares the weight change to achieve the technical effect of automatically detecting the actual feeding weight of the abrasive sand. The second single-chip microcomputer receives the actual discharge amount signal and compares it with the set weight signal. When the actual feeding weight reaches the set weight value, the second single-chip microcomputer controls the servo motor to stop running and controls the buzzer to sound a warning sound.

[0025] By adopting the above technical solution, the two limit plates and the limit rod cooperate with each other to limit the rotation angle of the feeding bracket, which can reduce the situation where the operator rotates the feeding bracket too much and causes the feeding bracket to collide with other equipment in the workshop.

[0026] Preferably, a reinforcing rib is fixedly connected to the mounting post, one end of the reinforcing rib away from the mounting post is fixedly connected to the second mounting plate, and the reinforcing rib is pressed tightly between the mounting post and the second mounting plate.

[0028] Preferably, a sealing cover is threadedly connected at the discharge port of the discharge channel.

[0029] By adopting the above technical solution, the sealing cover can prevent the grinding sand in the feeding hopper and the discharging channel from flowing out and polluting the frame.

[0031] 1. Through the coordination and use of the control panel, the servo motor, the auger, the weighing sensor, the first single-chip microcomputer and the second single-chip microcomputer, the grinding sand can be quantitatively added to the grinding disc according to the weight of the grinding sand pre-set by the operator, which can save the operator from the operation of manually weighing the grinding sand, thereby improving the convenience of the operator in using the grinding device;

[0032] 2. By setting the buzzer, a warning sound can be issued to remind the operator when the amount of grinding sand reaches the set weight, which can further improve the convenience of the operator in using the grinding device;

[0037] The following is combined with Figure 1-2 This application is described in further detail.

[0038] Example

[0039] The embodiment of the present application discloses a one-step formed valve flap grinding device. Figure 1 It mainly includes a frame 1, on which a feeding bracket 2 is rotatably connected, on which a feeding hopper 3 is detachably mounted, and a discharging channel 31 is connected to the bottom of the feeding hopper 3, and the discharging channel 31 is mounted above the grinding disc 4.

[0040] And: a control panel, fixedly mounted on the frame 1, for inputting a set weight signal and a start signal; a discharging mechanism 5, installed in the feeding hopper 3, and connected to the signal output terminal of the control panel for receiving a start signal and driving the abrasive sand in the hopper to flow out through the discharging channel 31; a discharging control module, installed on the feeding bracket 2, and connected to the signal input terminal of the control panel for receiving a start signal and detecting the abrasive sand discharge amount, and outputting a control signal when the abrasive sand discharge amount reaches the set weight; a buzzer 6, fixedly mounted on the feeding bracket 2, and connected to the signal output terminal of the discharging control module for receiving a control signal and issuing a warning sound; the signal input terminal of the discharging mechanism 5 is connected to the signal input terminal of the discharging control module, and the discharging mechanism 5 receives the control signal and stops discharging.

[0041] Before using the valve disc grinder, the operator can first rotate the feeding bracket 2 on the frame 1 until the discharge channel 31 of the feeding hopper 3 is located above the grinding disc 4. After the operator pours the grinding sand into the feeding hopper 3, the operator can set the required grinding sand weight through the control panel and input the start signal; after receiving the start signal, the discharge mechanism 5 drives the grinding sand in the feeding hopper 3 to be transported to the surface of the grinding disc 4 through the discharge channel 31; in the process of the discharge mechanism 5 outputting the grinding sand, the discharge control module detects the discharge amount of the grinding sand in real time, and controls the discharge mechanism 5 to stop feeding when the discharge amount of the grinding sand reaches the set weight, and at the same time controls the sound and light alarm to emit a warning sound.

[0042] By coordinating and using the control panel, the discharging mechanism 5, the discharging control module and the buzzer 6, the technical effect of automatic and quantitative feeding of abrasive sand can be achieved, eliminating the operator's need to manually weigh and feed the abrasive paste. When the amount of abrasive sand fed reaches the set weight, the buzzer 6 emits a prompt sound, and the operator knows that the feeding of the abrasive sand has been completed, which can further improve the convenience of the operator in using the grinding device.

[0043] In addition, since the feeding bracket 2 is rotatably installed on the frame 1, when the operator finishes feeding, the feeding bracket 2 can be rotated away from the top of the grinding disc 4, which is convenient for the operator to spread the grinding sand, place the valve disc, etc.

[0045] During the process of feeding the abrasive sand, the servo motor 51 drives the auger 52 to rotate at a constant speed, so that the abrasive sand in the feeding hopper 3 flows out along the spiral blades of the auger 52, thereby achieving the technical effect of automatically feeding the abrasive sand.

[0046] Reference Figure 1 The feeding bracket 2 includes a second mounting plate 22 , which is located below the first mounting plate 21 . An extension portion 32 is provided on the top of the feeding hopper 3 and extends outward. The extension portion 32 is located on the second mounting plate 22 .

[0048] During the process of adding abrasive sand, the weighing sensor 7 detects the weight of the abrasive sand in the feeding hopper 3 in real time. By comparing the weight change through the first single-chip microcomputer, the technical effect of automatically detecting the actual feeding weight of the abrasive sand can be achieved. The second single-chip microcomputer receives the actual discharge amount signal and compares it with the set weight signal. When the actual feeding weight reaches the set weight value, the second single-chip microcomputer controls the servo motor 51 to stop running, and at the same time controls the buzzer 6 to sound a warning sound.

[0050] The two limit plates 25 and the limit rod 24 cooperate with each other to limit the rotation angle of the feeding bracket 2, thereby reducing the possibility that the feeding bracket 2 collides with other equipment in the workshop due to the operator rotating the feeding bracket 2 too much.

[0051] It should be noted that a rotating shaft is fixedly connected to the bottom of the mounting column 23 , and the rotating shaft is rotatably connected to the inside of the frame 1 .

The reinforcing rib 26 can improve the structural strength of the connection between the second mounting plate 22 and the mounting column 23, and improve the load-bearing capacity of the second mounting plate 22.

[0053] Reference Figure 1 The discharge port of the discharge channel 31 is threadedly connected with a cover 33. The cover 33 can prevent the grinding sand in the feeding hopper 3 and the discharge channel 31 from flowing out and polluting the frame 1.
