Description

Technical Field

[0001] This utility model belongs to the field of vehicle tipping technology, specifically relating to a vehicle tipping mechanism for thermal power plants. Background Technology

[0002] A tippler is a large mechanical device used to unload bulk materials from open railway wagons. It is a loading and unloading machine that can tilt or tilt rail vehicles to unload materials.

[0003] When it is necessary to tip over the car body, the car body is first moved into the tipping seat, and then clamped and tipped over to dump the materials inside. When fixing the car body, the traditional method is to fix it by pressing directly. When tipping over, the car body will slide to the sides and separate from the tipping seat, which may cause the car body to fall and be damaged. Therefore, this utility model proposes a car tipper clamping mechanism for thermal power plants to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a car-clamping mechanism for a tippler in a thermal power plant, in order to solve the problems mentioned in the background art.

[0005] The technical solution adopted by this utility model is:

[0006] A tippler clamping mechanism for a thermal power plant, comprising:

[0007] support;

[0008] A rotating seat is rotatably mounted on top of a bracket and has a clamping assembly inside for clamping the carriage.

[0009] A limiting component, located at the connection between the bracket and the rotating base, is used to limit the movement of the rotating base;

[0010] A rotating component, located at the connection between the bracket and the rotating base, is used to drive the rotating base to rotate;

[0011] The blocking components, located on both sides of the rotating seat, are used to prevent the carriage from moving.

[0012] Furthermore, the main body of the rotating seat is a circular frame, and guide rails are fixedly connected to the left and right sides of the inner wall of the circular frame. The carriage slides into the rotating seat through the guide rails.

[0013] Furthermore, the limiting component includes a support block and two arc-shaped blocks; circular grooves are opened on both the front and rear end faces of the rotating seat; the bracket is U-shaped in general; arc-shaped blocks are fixed on the inner walls of the front and rear sides of the bracket at the corresponding positions of the circular grooves; the arc-shaped blocks are slidably inserted into the circular grooves; the bottom of the rotating seat is rotatably mounted on the support block; and the support block is fixedly connected to the inner wall of the bottom end of the bracket.

[0014] Furthermore, the upper surface of the support block is an arc surface that mates with the rotating seat.

[0015] Furthermore, the rotating assembly includes drive teeth symmetrically arranged at the front and rear ends of the rotating seat, a first gear meshing with the bottom of the drive teeth, and a motor for driving the first gear to rotate.

[0016] Furthermore, the clamping assembly includes multiple pressing blocks, multiple driving rods, two horizontal plates, and two cylinders; the circular frame of the rotating seat has protruding cavities on both the left and right sides. Each cavity is equipped with a cylinder and a horizontal plate fixed to the extension end of the cylinder. Each horizontal plate is fixed with multiple vertical driving rods. The upper end of each driving rod passes through a hole in the cavity and extends out of the cavity, and a pressing block is fixed thereon. The pressing blocks on the left and right sides press the carriage into the rotating seat.

[0017] Furthermore, a pressing groove is provided at the bottom of the pressing block, and the wall of the carriage is inserted into the pressing groove.

[0018] Furthermore, the blocking assembly includes blocking plates symmetrically arranged on the left and right sides of the rotating seat cavity. One side of the blocking plate is provided with a rotating component for driving the blocking plate to rotate. During the process of the two blocking plates rotating from the initial vertical state downward to the horizontal state, a portion of them can protrude out of the cavity to block the movement of the carriage.

[0019] Furthermore, the rotating component is disposed within the cavity and includes a connecting shaft fixedly connected to one side of the baffle plate, a second gear fixedly connected to the connecting shaft, and a toothed plate meshing with the second gear and vertically arranged. The connecting shaft is inserted into the inner wall of one side of the cavity, and the toothed plate is fixedly connected to the bottom end of the horizontal plate.

[0020] Compared with the prior art, the present invention has the following advantages:

[0021] This invention, through the design of a baffle plate and a rotating component, first clamps the carriage with a clamping component when it is moved into the interior of the rotating seat. Then, the rotating component drives the baffle plate to move to both sides of the carriage. The baffle plate prevents the carriage from moving and avoids damage caused by the carriage sliding and falling when it is overturned. Attached Figure Description

[0027] To better understand the purpose, structure, and function of this utility model, a more detailed description of this utility model will be provided below with reference to the accompanying drawings.

[0028] like Figure 1 As shown, this utility model provides a car clamping mechanism for a tippler in a thermal power plant, including...

[0029] Bracket 1;

[0030] The rotating seat 2 is rotatably mounted on the top of the bracket 1, and a clamping assembly 5 is installed inside for clamping the carriage.

[0031] The limiting component 3 is located at the connection between the bracket 1 and the rotating base 2, and is used to limit the movement of the rotating base 2;

[0032] Rotating component 4 is located at the connection between bracket 1 and rotating base 2, and is used to drive rotating base 2 to rotate;

[0033] The blocking components 6 are located on both sides of the rotating seat 2 and are used to block the movement of the carriage.

[0034] like Figure 1 As shown, the main body of the rotating seat 2 is a circular frame, and guide rails 202 are fixedly connected to the left and right sides of the inner wall of the circular frame. The carriage slides into the rotating seat 2 through the guide rails 202.

[0035] It should be noted that during use, the carriage enters the interior of the rotating seat 2 via the guide rail 202. When moving the carriage into the interior of the rotating seat 2, the carriage is first clamped by the clamping assembly 5, and then the rotating component drives the baffle plate 601 to move to both sides of the carriage. The baffle plate 601 prevents the carriage from moving, thus avoiding damage caused by the carriage sliding and falling when it is being overturned.

[0036] like Figure 1 , Figure 2As shown, the limiting component 3 includes a support block 303 and two arc-shaped blocks 302; circular grooves 301 are opened on both the front and rear end faces of the rotating seat 2; the bracket 1 is U-shaped in general; arc-shaped blocks 302 are fixed on the inner walls of the front and rear sides of the bracket 1 at the corresponding positions of the circular grooves 301; the arc-shaped blocks 302 are slidably inserted into the circular grooves 301; the bottom of the rotating seat 2 is rotatably mounted on the support block 303; the support block 303 is fixedly connected to the inner wall of the bottom end of the bracket 1; the support block 303 is used to support the rotating seat 2.

[0037] It should be noted that the upper surface of the support block 303 is an arc surface that mates with the rotating seat 2. The support block 303 supports the rotating seat 2 and allows the rotating seat 2 to rotate on the top of the support block 303. The circular groove 301 is adapted to the arc block 302, and the arc edge of the arc block 302 fits against the inner wall of the circular groove 301, thus blocking the movement of the rotating seat 2.

[0038] like Figure 1 , Figure 2 As shown, the rotating assembly 4 includes drive teeth 401 symmetrically arranged at the front and rear ends of the rotating base 2, a first gear 402 meshing with the bottom of the drive teeth 401, and a motor 403 for driving the first gear 402 to rotate.

[0039] It should be noted that the motor 403 is an existing servo motor 403, which is used to drive the first gear 402 to rotate, and the rotating first gear 402 drives the rotating seat 2 with driving teeth 401 to rotate, thereby dumping the materials inside the carriage.

[0040] like Figure 1 , Figure 3 As shown, the clamping assembly 5 includes multiple pressing blocks 501, multiple driving rods 502, two horizontal plates 504, and two cylinders 503. The circular frame of the rotating seat 2 has protruding cavities 201 on both the left and right sides. Each cavity 201 is equipped with a cylinder 503 and a horizontal plate 504 fixed horizontally to the extension end of the cylinder 503. Multiple vertical driving rods 502 are fixed on each horizontal plate 504. The upper end of each driving rod 502 passes through a hole in the cavity 201 and extends out of the cavity 201, and a pressing block 501 is fixed thereon. The pressing blocks 501 on the left and right sides press the carriage into the rotating seat 2.

[0041] It should be noted that the bottom of the pressing block 501 is provided with a pressing groove. When the pressing block 501 moves to one side of the carriage, the carriage wall is inserted into the pressing groove. The cylinder 503 is an existing power element that converts the energy of compressed air into mechanical linear motion. Its core working principle is that compressed air pushes the piston to reciprocate in the sealed cavity. When compressed air enters the cylinder 503 from one end, the air pressure pushes the piston rod to extend or retract, thereby outputting thrust or pull. The reciprocating motion of the piston can be achieved by controlling the airflow direction through the reversing valve. In use, the cylinder 503 drives the horizontal plate 504 to move, and the horizontal plate 504 drives the driving rod 502 and the pressing block 501 to move. The pressing block 501 presses the carriage against the inner wall of the bottom of the rotating seat 2, and the carriage is clamped by this design.

[0042] like Figure 4 As shown, the blocking assembly 6 includes blocking plates 601 symmetrically arranged on the left and right sides of the cavity 201 of the rotating seat 2. One side of the blocking plate 601 is provided with a rotating component for driving the blocking plate 601 to rotate. During the process of the two blocking plates 601 rotating from the initial vertical state downward to the horizontal state, a part of them can protrude out of the cavity 201 to block the movement of the carriage.

[0043] The rotating component is disposed in the cavity 201 and includes a connecting shaft 603 fixedly connected to one side of the baffle plate 601, a second gear 602 fixedly connected to the connecting shaft 603, and a toothed plate 604 meshing with the second gear 602 and vertically arranged. The connecting shaft 603 is inserted into the inner wall of one side of the cavity 201, and the toothed plate 604 is fixedly connected to the bottom end of the horizontal plate 504.

[0044] It should be noted that the baffle plate 601 and the second gear 602 are respectively attached to the side wall of the rotating seat 2 and the inner wall of one side of the cavity 201, and are connected by the connecting shaft 603. This design restricts the position of the baffle plate 601 and the second gear 602. The second gear 602 is adapted to the toothed plate 604. When the cylinder 503 drives the horizontal plate 504 and the pressing block 501 to move, the horizontal plate 504 moves the position of the toothed plate 604, and the toothed plate 604 drives the second gear 602 to rotate. The second gear 602 drives the baffle plate 601 to rotate. When the pressing block 501 moves to be in contact with the carriage, the second gear 602 rotates 90 degrees and the baffle plate 601 rotates 90 degrees with the connecting shaft 603.
