Description

Technical Field

[0001] This utility model belongs to the technical field of curved coal chutes structure design, specifically relating to a pipe angle adjustment joint device for curved coal chutes. Background Technology

[0002] In industrial sectors such as coal mining, thermal power generation, coking, and coal transportation, curved coal chutes are one of the core pieces of equipment for the directional conveying of coal particles. Because the on-site conveying path needs to be flexibly adjusted according to the plant layout, equipment location, and material flow direction, curved coal chutes often require pipe angle adjustment joints to connect different sections of the pipeline, ensuring smooth material conveying and avoiding problems such as coal blockage and spillage. The pipe angle adjustment joints of curved coal chutes mostly use flange connections, with bolts used to tighten the flanges of the two pipeline sections to achieve sealing and fixation.

[0003] Existing flange-type pipe fittings mostly lack positioning structures during use. Installation requires manual, repeated alignment of the bolt holes on the two flange sections. Furthermore, before the bolts are fully tightened, the two pipe sections lack an effective initial fixing mechanism. Due to factors such as the pipe's own weight, the initially aligned flanges are prone to displacement, causing the bolt holes to misalign again, necessitating readjustment. This process is quite cumbersome. Therefore, we propose a pipe angle adjustment fitting device for curved coal chutes. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a pipe angle adjustment pipe joint device for curved coal chutes. It solves the problems that flange-type pipe joints mostly lack positioning structures during use, requiring manual and repeated alignment of the bolt holes of the two flange sections during installation. Furthermore, before the bolts are fully tightened, the two pipe sections lack an effective initial fixing mechanism. Due to factors such as the weight of the pipe itself, the initially aligned flanges are prone to displacement, causing the holes to misalign again, requiring readjustment and making the work process cumbersome.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A pipe angle adjusting fitting device for a curved coal chute includes a first flange and a second flange. A second connecting pipe is fixedly connected to one end of the second flange. A fixing ring is fixedly connected to the outer side of the second flange. A rotating ring is rotatably connected to the inner wall of the fixing ring. Pressure rods are fixedly connected at equal intervals to the top of the rotating ring. Limiting rods are fixedly connected at equal intervals to the inner wall of the fixing ring. A locking block is slidably connected to the outer side of the limiting rod.

[0006] As a preferred embodiment, a connecting block is fixedly connected to one side of the card block, and the connecting block has an inclined groove inside that cooperates with the pressure rod.

[0007] As a preferred embodiment, a first connecting pipe is fixedly connected to one end of the first flange, and a positioning post is fixedly connected at equal intervals to one side of the first flange, with a connecting groove provided inside the positioning post.

[0008] In a preferred embodiment, the fixing ring has equidistant positioning grooves inside for use with positioning posts. These positioning grooves allow for proper positioning during the installation of the first and second flanges.

[0009] As a preferred embodiment, a reset spring is sleeved on the outer side of the limiting rod and on one side of the locking block. The reset spring can drive the locking block to move and reset.

[0010] As a preferred embodiment, the number of the locking blocks is four, and the four locking blocks are arranged in an array. The four sets of locking blocks can be used to initially fix the first flange and the second flange, which facilitates the subsequent fixing of the first flange and the second flange with bolts.

[0011] As a preferred embodiment, a push rod is fixedly connected to the outer side of the rotating ring, and the push rod can drive the rotating ring to rotate.

[0012] As a preferred embodiment, the push rod is fitted with an anti-slip pad on its outer side. The anti-slip pad increases friction and facilitates pushing the push rod.

[0013] Compared with the prior art, this utility model has the following advantages: This utility model achieves the function of pre-positioning and initial fixing during installation between the first flange and the second flange by setting a push rod, rotating ring, pressure rod, connecting block, locking block, return spring, positioning column, positioning groove and connecting groove, so that the holes are aligned with each other, which facilitates the subsequent installation and fixing of the first flange and the second flange with bolts, and enhances the stability of the pipe joint.

[0021] Please see Figures 1 to 6 As shown, this utility model embodiment provides a pipe angle adjusting pipe joint device for curved coal chutes, including a first flange 1 and a second flange 4. A second connecting pipe 5 is fixedly connected to one end of the second flange 4. A fixing ring 3 is fixedly connected to the outer side of the second flange 4. A rotating ring 11 is rotatably connected to the inner wall of the fixing ring 3. A pressure rod 12 is fixedly connected at equal intervals to the top of the rotating ring 11. A limit rod 10 is fixedly connected at equal intervals to the inner wall of the fixing ring 3. A locking block 13 is slidably connected to the outer side of the limit rod 10. A connecting block 16 is fixedly connected to one side of the locking block 13. An inclined groove 15 that cooperates with the pressure rod 12 is opened inside the connecting block 16. A first connecting pipe 2 is fixedly connected to one end of the first flange 1. A positioning column 6 is fixedly connected at equal intervals to one side of the first flange 1. A connecting groove 7 is opened inside the positioning column 6. In this embodiment, the locking block 13 moves into the interior of the connecting groove 7, which can be used for positioning and initial fixing during installation between the first flange 1 and the second flange 4, so that the holes are aligned with each other, which facilitates the subsequent installation and fixing between the first flange 1 and the second flange 4 with bolts, thereby enhancing the stability of the pipe joint.

[0022] Please see Figure 2 and Figure 4 As shown, in this embodiment, the fixing ring 3 has equidistant positioning grooves 8 that cooperate with the positioning post 6; a return spring 9 is sleeved on the outer side of the limiting rod 10 and on one side of the locking block 13; there are four locking blocks 13, which are arranged in an array. The positioning grooves 8 can cooperate with the positioning post 6 to position the first flange 1 and the second flange 4 during installation, and the return spring 9 can drive the locking block 13 to move and reset.

[0023] Please see Figure 5As shown, a push rod 14 is fixedly connected to the outer side of the rotating ring 11; an anti-slip pad is sleeved on the outer side of the push rod 14. The anti-slip pad increases friction and facilitates pushing the push rod 14. The push rod 14 can drive the rotating ring 11 to rotate.

[0024] When using this invention, at the pipe angle adjustment joint of the curved coal drop pipe, where a flange is needed to connect the pipe joint, the positioning pin 6 is pushed into the positioning groove 8. During the pushing process, because one side of the locking block 13 is inclined, the positioning pin 6 will squeeze and drive the locking block 13 to slide along the limiting rod 10, compressing the return spring 9. As the positioning pin 6 continues to move, the return spring 9 will drive the locking block 13 to move and reset due to its elasticity, thereby moving the locking block 13 into the interior of the connecting groove 7. This allows for positioning and initial fixing during installation between the first flange 1 and the second flange 4, ensuring that the holes are aligned with each other. This facilitates subsequent installation and fixation of the first flange 1 and the second flange 4 using bolts, enhancing the stability of the pipe joint. When it is necessary to separate the first flange 1 and the second flange 4, unscrew the bolts and rotate the push rod 14. The push rod 14 drives the rotating ring 11 to rotate, and the rotating ring 11 drives multiple pressure rods 12 to move, so that the pressure rods 12 cooperate with the inclined groove 15. Thus, during the rotation of the rotating ring 11, it squeezes and drives the connecting block 16 to slide. The connecting block 16 drives the locking block 13 to move and disengage from the connecting groove 7, thereby separating the first flange 1 and the second flange 4. The operation is convenient.
