Description

Technical Field

[0001] The utility model relates to the technical field of alarm brackets, in particular to an anti-tipping bracket. Background Art

[0002] The existing double-deck relaxation screen is connected to the support base by shock-absorbing springs. When the machine is working, if the viscosity of coal gangue is normal, the connection between the two is reliable, and the probability of an accident is extremely small; if the viscosity of coal gangue is large and the screening efficiency is poor, it is easy to cause coal gangue to accumulate and tilt the screen body, resulting in a safety accident, posing a great safety hazard. On the current market, two blocking plates are mostly installed on both sides of the base. Although the blocking plates can play a certain role in preventing tilting to a certain extent, in most cases, the F that the blocking plates can block is limited. When the staff fails to detect the accumulation phenomenon in time, the tipping situation will still occur. Content of the Utility Model

[0030] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the following will provide a detailed description of the specific embodiments of the present utility model in conjunction with the drawings of the specification.

[0031] In the following description, many specific details are set forth to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from the description herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0032] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that can be included in at least one implementation manner of the present utility model. The "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an individual or selectively mutually exclusive embodiment with other embodiments.

[0033] Embodiment 1

[0034] Refer to Figures 1 to 4 , which is the first embodiment of the present utility model. This embodiment provides an installation unit 100,

[0035] The rotating unit 200 includes a mounting bracket 201 disposed on the mounting unit 100, a rotating plate 202 rotatably disposed on the mounting bracket 201, a connecting plate 205 disposed on the rotating plate 202, a connecting rod 206 disposed on one side of the rotating plate 202, and a first elastic component 207 rotatably disposed at one end of the connecting rod 206;

[0036] The transmission unit 300 is disposed on one side of the rotating plate 202;

[0037] The judging unit 400 is disposed at the bottom end of the transmission unit 300;

[0038] The alarm switch 500 is disposed at the bottom end of the judging unit 400.

[0039] It should be noted that the mounting bracket 201 is fixedly mounted on the top of the mounting unit 100 by bolts. The rotating plate 202 is rotatably connected to the mounting bracket 201. The rotating plate 202 is made of medium-density fiberboard with high hardness. A sheet-shaped protrusion is provided on one side of the rotating end of the rotating plate 202, which can facilitate the connection with the connecting plate 205 by bolts. A connecting rod 206 is fixedly welded to the side of the connecting plate 205 away from the mounting bracket 201. One end of the connecting rod 206 is rotatably connected to a first elastic component 207. The first elastic component 207 will upwardly press the connecting rod 206, so that the rotating plate 202 can always be in contact with the sieve body.

[0040] Furthermore, the mounting unit 100 includes a vertical plate 101, a connecting piece 102 disposed on one side of the vertical plate 101, and a reinforcing piece 103 disposed between the vertical plate 101 and the connecting piece 102.

[0041] It should be noted that the connecting piece 102 is fixedly welded to one side of the vertical plate 101, and the number of the connecting pieces 102 is preferably two. The base of the double-layer relaxation sieve is inserted between the two connecting pieces 102 and fixed with multiple bolts. The structure will be more stable during connection. And the reinforcing piece 103 is set in a "triangle" shape, and its two right-angled sides are respectively on one side of the vertical plate 101 and the connecting piece 102, making the connection between the two more reliable.

[0042] Furthermore, the first elastic component 207 includes a first fixing rod 207a, a first extension rod 207b slidably disposed on the outer wall of the first fixing rod 207a, a limiting piece 207c disposed at the bottom end of the first fixing rod 207a, and a first spring 207d disposed below the limiting piece 207c.

[0043] It should be noted that the first fixed rod 207a is slidably connected to the first extension rod 207b, and a limiting plate 207c is fixedly connected to the bottom end of the first fixed rod 207a, and the limiting plate 207c can prevent the first fixed rod 207a from falling off the first extension rod 207b. A first spring 207d is arranged between the first fixed rod 207a and the first extension rod 207b, and the first spring is in a contracted state. One end of the first extension rod 207b is rotatably connected to one side of the installation unit 100, and the rotation point is limited and fixed, so the first spring 207d will squeeze the first fixed rod 207a upward. Since one end of the first fixed rod 207a is rotatably connected to one end of the connecting rod 206, the effect of squeezing one end of the connecting rod 206 upward is achieved.

[0044] When in use, the device is installed on the base by inserting the base of the double-layered relaxation screen between the two connecting pieces 102 and inserting multiple bolts. Before inserting the base of the double-layered relaxation screen between the connecting pieces 102, it is necessary to bend the rotating plate 202 upward until one end of the rotating plate 202 is higher than the top plate of the screen body (specifically, the connection between the screen body and the base, the mounting plate fixedly connected to the top of the spring and fixedly welded to the screen body). As the base is inserted, when the top plate of the screen body is within the rotation radius of the rotating plate 202, the rotating plate 202 is released. The rotating plate 202 will press the top plate of the screen body tightly under the elastic force of the first spring 207d, and the height of the top plate of the screen body will be sensed in real time. When material accumulates in the screen body, the top plate of the screen plate will gradually move upward. Since the rotating plate 202 is always in contact with the screen The top plate of the plate is in close contact, so the rotating plate 202 will rotate on the mounting frame 201, and the angle is getting larger and larger. When the rotating plate 202 rotates, the transmission unit 300 will transmit the rotation angle of the rotating plate 202 to the judgment unit 400 for judgment. When the rotation angle of the rotating plate 202 is within the danger range (the judgment of the danger range here is preset in advance, and the preset standard is when the screen body is abnormally tilted, the top plate of the screen body drives the rotating plate 202 to form a rotation angle, and this angle is the starting point of the danger range angle. The preset starting point value range of the danger angle is 35°~60°, and the preferred preset starting point value is set according to the installation of different tension and relaxation screens), the judgment unit 400 will immediately start the alarm switch 500 and sound an alarm until the threat of screen tipping is eliminated.

[0045] In summary, the rotating plate 202 rotates with the displacement of the top plate of the screen body, and the rotation angle is transmitted to the judgment unit 400 through the transmission unit 300 to judge whether it enters the set danger range. If it enters the danger range, the judgment unit 400 will activate the alarm switch to sound an alarm until the danger is eliminated. This structure detects dangerous trends in advance and issues an alarm to notify the operator, so that the operator can shut down the machine in time to protect the machine and reduce the probability of machine damage.

[0046] Embodiment 2

[0047] Referring to Figures 1 to 5 , this is the second embodiment of the present utility model based on Embodiment 1. The transmission unit 300 includes a linear component 301 disposed on the mounting unit 100, a mounting seat 302 disposed on the moving end of the linear component 301, a rotating rod 303 rotatably disposed on the mounting seat 302, a positioning rod 304 rotatably disposed at the top of the rotating rod 303, and a transmission rod 305 disposed on the mounting seat 302;

[0048] The positioning rod 304 is fixedly installed on one side of the rotating plate 202.

[0049] Furthermore, the linear component 301 includes a slide rail 301a disposed on the mounting unit 100, and a slider 301b slidably disposed on the slide rail 301a.

[0050] It should be noted that the mounting seat 302 is fixedly installed on the slide rail 301a by bolts. The rotating rod 303 is rotatably connected to the upper part of the mounting seat 302. The positioning rod 304 is rotatably connected to the top of the rotating rod 303. There are protrusions on the positioning rod 304 to limit the rotating rod 303. The positioning rod 304 is fixed on the rotating plate 202 by bolts. The transmission rod 305 is fixedly installed on the mounting seat 302 by bolts and is located below the rotating rod 303.

[0051] During use, when the rotating plate 202 rotates, the positioning rod 304 makes a circular motion around the mounting frame 201. The connection point between the positioning rod 304 and the rotating rod 304 will move upward, thereby pulling the slider 302b to perform a vertical upward displacement on the slide rail 302a through the rotating rod 304. The slider 302b drives the transmission rod 305 to perform a vertical upward displacement through the mounting seat 302, changing the judgment of the rotation angle to the judgment of the displacement length.

[0052] In summary, changing the rotation angle generated by the rotating plate 202 to the displacement length not only realizes the transmission of the rotation signal, but also reduces the space occupation rate of the device to a certain extent.

[0053] Embodiment 3

[0054] Referring to Figures 1 to 7 , this is the third embodiment of the present utility model based on Embodiment 2. The judgment unit 400 includes a mounting shell 401, a lifting plate 402 slidably disposed in the inner cavity of the mounting shell 401, a second spring 403 disposed between the upper surface of the lifting plate 402 and the mounting shell 401, a second elastic component 404 disposed on the lower surface of the lifting plate 402, and a connection cap 405 disposed at the output end of the second elastic component 404;

[0055] The transmission rod 305 sequentially penetrates through the top end of the installation shell 401 and the lifting plate 402.

[0056] Furthermore, the installation shell 401 includes a shell body 401a and a cover plate 401b provided on the shell body 401a.

[0057] Furthermore, the second elastic component 404 includes a second fixing rod 404a, a second extension rod 404b slidably disposed on the second fixing rod 404a, and a tension spring 404c disposed between the second fixing rod 404a and the second extension rod 404b.

[0058] Furthermore, a "disc-shaped" protrusion is provided at the bottom end of the transmission rod 305.

[0059] Furthermore, the alarm switch 500 is fixedly installed at the bottom end of the shell body 401a.

[0060] It should be noted that when the disc-shaped protrusion provided at the bottom of the transmission rod 305 moves upward following the transmission rod 305, it will push the lifting plate 402 upward. The transmission rod 305 penetrates through the shell body 401a and the lifting plate 402. The distance between the disc-shaped protrusion of the transmission rod 305 and the lifting plate 402 is the safe range. The top end of the second spring 403 is fixedly connected to the top of the inner cavity of the shell body 401a, and the bottom end of the second spring 403 is fixedly connected to the upper surface of the lifting plate 402. The second fixing rod 404a and the second extension rod 404b are slidably connected, and the two are connected by a tension spring 404c. After the alarm switch 500 has been triggered, if the machine continues to operate, the lifting plate 402 will continue to rise, which will pull the first fixing rod 404a to extend on the second extension rod 404b, effectively preventing the problem that the alarm switch 500 is damaged due to excessive pressure.

[0061] During use, the transmission rod 305 moves continuously upward. The protrusion at the bottom of the transmission rod 305 does not contact the lifting plate. At this time, it is the safe range. When reaching the dangerous range, the protrusion at the bottom of the transmission rod 305 contacts the lifting plate 402, and the lifting plate 402 moves upward. At this time, the judgment unit 400 issues a danger alarm. Driven by the transmission rod 305, the lifting plate 402 continues to move upward. The lifting plate 402 drives the second elastic component 404 to move upward. The second elastic component 404 presses the alarm switch 500 through the connection cap 405 to turn on the alarm. And if the machine continues to operate, the lifting plate 402 will continue to rise, which will pull the first fixing rod 404a to extend on the second extension rod 404b, causing the alarm switch 500 to keep alarming continuously.

[0062] In summary, by setting the lifting plate 402 at the intersection of the safe displacement length and the dangerous displacement length, the inclination of the top plate of the sieve body can be monitored in real time, and the alarm switch 500 can be activated in a timely manner according to the inclination condition, making the judgment of danger more accurate. Moreover, the lifting plate 402 activates the alarm switch 500 through an elastic component that can be extended, enabling the alarm switch 500 to be in an alarm state during the upward movement of the lifting plate 402, and preventing the alarm switch 500 from being damaged due to excessive pressure.

[0063] Importantly, the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
