Description

Technical Field

[0001] This utility model relates to the field of coal conveying technology, and in particular to an air hammer vibrating device for coal bunkers. Background Technology

[0002] Steel coal bunkers are crucial equipment in thermal power plants, primarily used for storing raw coal. Their outlets are equipped with electric gate valves, coal chutes, and weighing feeders. Under normal circumstances, steel coal bunkers do not experience blockages when using coal according to design standards. However, due to factors such as coal moisture content and type, blockages can occur at the bunker outlet, gate valve, and coal chute inlet of the feeder. In severe cases, complete blockages can prevent the weighing feeder from supplying coal, affecting stable combustion in the furnace and power generation efficiency, resulting in significant economic losses. Patent CN216334212U discloses a coal bunker outlet unblocking and vibrating device. This device uses pneumatically driven hammers to periodically hammer an arc plate installed on the steel coal bunker, effectively cleaning residual coal and preventing blockages. The vibration isolation device between the shell and the solenoid valve effectively improves the reliability and lifespan of the entire system.

[0003] Because the hammer is used for long-term impact, it needs to be inspected or replaced regularly. However, when this dredging and rapping device is inspected or replaced, it is necessary not only to remove the cylinder pipe interface, but also to remove the sealing plate at the end of the housing and pull the cylinder out from the end of the housing. The operation is cumbersome, time-consuming and inefficient, resulting in a reduction in the efficiency of coal bunker dredging. Summary of the Invention

[0011] According to the technical solution provided in the embodiments of this application, one end of the reinforcing rod is provided with a first threaded post, and the other end is provided with a second threaded post. The outer diameter of the first threaded post is equal to the outer diameter of the reinforcing rod, and the outer diameter of the second threaded post is greater than the outer diameter of the first threaded post.

[0012] The two fasteners are a first internal thread block that is threadedly connected to the first threaded post, and a second internal thread block that is threadedly connected to the second threaded post.

[0013] According to the technical solution provided in the embodiments of this application, the reinforcing rod is provided with a first retaining ring near the end of the first threaded post, and the second threaded post is provided with a second retaining ring away from the end of the first threaded post.

[0014] According to the technical solution provided in the embodiments of this application, the bottom end of the housing is further provided with a storage component. The storage component includes a storage plate disposed below the housing and connected to the sleeve. When the sleeve is in a first state, the normal direction of the storage plate is a first direction. When the sleeve is in a second state, the normal direction of the storage plate is a third direction. The first direction, the second direction and the third direction are perpendicular to each other.

[0015] According to the technical solution provided in the embodiments of this application, the bottom surface of the sleeve is hinged to the placement plate near the arc-shaped pad, and the axis of the hinge shaft is in the second direction. The bottom end of the housing is equipped with a limiting rod through a locking member, and the extension direction of the limiting rod is in the first direction. The bottom surface of the sleeve away from the arc-shaped pad is provided with a limiting collar fitted outside the limiting rod.

[0020] In addition, a reinforcing component is installed inside the inspection port. The first threaded post of the reinforcing rod is connected to the first internal threaded block, and the second threaded post is connected to the second internal threaded block. This improves the brightness of the inspection port and avoids the problem of reduced shell strength caused by the opening of the inspection port. The reinforcing rod can also be removed after the threads are separated, making the operation of inspection or replacement of hammer head more convenient.

[0021] Furthermore, a limiting rod, a storage plate, and a limiting collar are provided. The limiting collar and the limiting rod ensure stable axial movement of the sleeve and prevent axial rotation. As the sleeve moves the storage plate, the limiting rod pushes the storage plate from a vertical position to a horizontal position, making it convenient for users to store tools during maintenance or replacement without placing them on the ground. This improves the convenience and efficiency of maintenance or replacement.

[0033] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0034] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0035] Please refer to Figures 1-4 An embodiment of this utility model provides an air hammer vibrating device for coal bunkers, comprising:

[0036] The shell 1, with its axis in the first direction, is connected to the coal bunker at one end via an arc-shaped pad 13; the first direction is... Figure 1 In the left and right direction, its left end is connected to the coal bunker through the arc-shaped pad 13, and the hammer 11 inside is also located in the left half of the shell 1.

[0037] The disassembly and assembly mechanism 2 includes an inspection port 22 located near the coal bunker end of the shell 1 and symmetrically arranged along the second direction. A sleeve 21 is slidably fitted on the shell 1 at the position corresponding to the inspection port 22. Sealing rings 23 are fitted on both sides of the outer surface of the shell 1 along the first direction corresponding to the inspection port 22. The first direction is perpendicular to the second direction.

[0038] One end of the housing 1 is provided with a reinforcing rib 14 that connects to the arc-shaped pad 13. One side of the housing 1 is provided with a hose interface 12. Several positioning blocks 24 are arranged around the outer surface of the housing 1 corresponding to the position of the hose interface 12. The sleeve 21 has a first state and a second state. When it is in the first state, one end of the sleeve 21 is in contact with the positioning block 24 and the inspection port 22 is exposed. When it is in the second state, the other end of the sleeve 21 is in contact with the reinforcing rib 14 and the inspection port 22 is blocked.

[0039] like Figure 1 and Figure 2 As shown, sliding the sleeve 21 to the right causes the right end of the sleeve 21 to contact the positioning block 24, thereby exposing the inspection port 22 for maintenance or replacement of the hammer head 11. Sliding the sleeve 21 to the left causes the left end of the sleeve 21 to contact the reinforcing rib 14, blocking the inspection port 22. The two ends of the sleeve 21 are then sealed by the sealing ring 23, preventing coal ash and dust from entering the housing 1 through the inspection port 22 and avoiding cylinder blockage. Because pushing the sleeve 21 can quickly position it, the inspection port 22 can be quickly blocked or exposed, achieving the purpose of rapid maintenance.

[0040] In some embodiments, a reinforcing component 3 is provided at the location of the access port 22 on the housing 1. The reinforcing component 3 is used to improve the structural strength of the access port 22 and avoid the problem of reduced strength of the housing 1 caused by the opening of the access port 22.

[0041] In some embodiments, the reinforcing component 3 includes fixing members disposed on the inner wall of the housing 1 and located on both sides of the access port 22 along a first direction, and a reinforcing rod 31 is threadedly connected between the two fixing members, the axial direction of the reinforcing rod 31 being the first direction; Figure 2 and Figure 3 As shown, since the hammer 11 strikes the coal bunker in the left and right direction, the added reinforcing rod 31 can connect the left and right side walls of the inspection port 22, thereby improving the structural strength of the reinforced shell 1.

[0042] In some embodiments, the reinforcing rod 31 has a first threaded post 32 at one end and a second threaded post 34 at the other end. The outer diameter of the first threaded post 32 is equal to the outer diameter of the reinforcing rod 31, and the outer diameter of the second threaded post 34 is greater than the outer diameter of the first threaded post 32.

[0043] The two fasteners are a first internal threaded block 36 that is threadedly connected to the first threaded post 32, and a second internal threaded block 37 that is threadedly connected to the second threaded post 34.

[0044] like Figure 2 and Figure 3As shown, during assembly, the first threaded post 32 can pass through the second internal threaded block 37 and then be threadedly connected to the first internal threaded block 36. At the same time, the second threaded post 34 is threadedly connected to the second internal threaded block 37, thereby realizing the installation of the reinforcing rod 31.

[0045] In some embodiments, the reinforcing rod 31 is provided with a first retaining ring 33 near the end of the first threaded post 32, and the second threaded post 34 is provided with a second retaining ring 35 away from the end of the first threaded post 32.

[0046] like Figure 2 and Figure 3 As shown, during installation, the first retaining ring 33 abuts against the first internal threaded block 36, and the second retaining ring 35 abuts against the second internal threaded block 37, achieving rapid positioning and avoiding excessive rotation of the reinforcing rod 31, which could cause the reinforcing rod 31 to detach from the two fixing parts. Furthermore, because the first retaining ring 33 and the second retaining ring 35 have been set, even if one of them is damaged, accurate positioning can still be guaranteed.

[0047] In some embodiments, the bottom end of the housing 1 is further provided with a storage assembly 4. The storage assembly 4 includes a storage plate 45 disposed below the housing 1 and connected to the sleeve 21. When the sleeve 21 is in a first state, the normal direction of the storage plate 45 is a first direction. When the sleeve 21 is in a second state, the normal direction of the storage plate 45 is a third direction. The first direction, the second direction and the third direction are perpendicular to each other.

[0048] Among them, the third party is Figure 1 and Figure 2 The vertical direction in the middle, where the first state reference Figure 1 Second state reference Figure 2 By pushing the movable sleeve 21, the vertical shelf 45 can be transformed into a horizontal state. Users can store maintenance tools on the shelf 45, which solves the problem that tools need to be placed on the ground during maintenance and that they need to bend over every time they need to replace or temporarily place them, thereby improving maintenance efficiency.

[0049] In some embodiments, the bottom surface of the sleeve 21 is hinged to the end of the arc-shaped pad 13 and the placement plate 45, with the axis of the hinge shaft in the second direction. A limiting rod 41 is installed at the bottom of the housing 1 through a locking member 42, with the extension direction of the limiting rod 41 in the first direction. A limiting collar 43 is provided on the bottom surface of the sleeve 21 away from the arc-shaped pad 13 and fitted outside the limiting rod 41.

[0050] like Figure 1 and Figure 2As shown, because the limiting collar 43 is restricted by the limiting rod 41, it ensures that the sleeve 21 will not rotate axially during the movement to the right. Furthermore, when the sleeve 21 moves to the right, the bottom end of the shelf 45 contacts the left end of the limiting rod 41, and the limiting rod 41 pushes one side of the shelf 45, causing the shelf 45 to swing horizontally around the hinge axis, thereby realizing the switching of the shelf 45's state.

[0051] In some embodiments, the locking member 42 includes a screw rod located at the bottom end of the housing 1, a through hole for the screw rod to pass through on the limiting rod 41, and two nuts threadedly connected to the screw rod, the two nuts respectively abutting against the top and bottom surfaces of the limiting rod 41. Figure 2 As shown, the locking element 42 is a common locking structure that can ensure the stable installation of the limit rod 41. Furthermore, a rubber washer or a spring washer can be set to improve the stability of the nut installation.

[0052] In some embodiments, a bearing seat 44 is provided on the bottom surface of the sleeve 21 near the end of the arc-shaped pad 13, and bearing seats 44 are provided on both ends of the top surface of the shelf 45 along the second direction. A hinge shaft is installed through each bearing seat 44. The two bearing seats 44 of the shelf 45 are symmetrically distributed, and the bearing seat 44 at the bottom of the sleeve 21 is located between the two bearing seats 44, which ensures the stability of the hinge after the hinge shaft is installed.

[0053] In some embodiments, the bottom end of the shelf 45 is provided with a support groove that matches the width of the limiting rod 41, so that when the shelf 45 is in a horizontal state, the support groove can hold the limiting rod 41, thereby improving the stability of the shelf 45. In addition, the top end of the shelf 45 is provided with several storage slots that fit various tools, which can classify and store tools, making it convenient to store and retrieve them quickly, thereby improving the efficiency of tool use.

[0054] In some embodiments, the sleeve 21 is provided with handles 25 at both the front and rear ends to facilitate quick pulling of the sleeve 21.
