Abstract
Description
Technical Field
[0001] The utility model relates to the field of limiters, and more specifically, to a chain buffer limiter. Background Art
[0002] During the manufacturing production process, there are many initial raw materials that need to be temporarily stored or transferred and stacked. These stacking systems need to move back and forth within a certain stroke range. To ensure that the movement of the stacking system does not deviate or exceed the original trajectory, limiters are set at both ends or multiple points of the stroke. These limiters play a role in protection and reminder, preventing the equipment from moving beyond the range and causing unnecessary damage to personnel and equipment. The currently used limiters are mainly composed of two types. One is a fixed baffle or stop iron that plays an isolation and anti-collision role; the other is a chain switch that emits a stop signal after being touched, causing the stacking system to stop running.
[0003] However, during the use of the existing limiters, the following problems still exist:
[0004] 1. The first type of limiter such as an isolation stop iron is similar to a fixed stroke range. It mainly directly contacts and collides with a firm position to protect the protected area from damage. However, if the operator is inattentive, it is easy to cause the equipment to continuously operate under overload, and the isolation stop iron limiter is prone to wear and fall off, failing to play a limiting role.
[0005] 2. The second type of chain switch is sensitive and convenient, but it causes the equipment system to stop running, which will have a certain impact on production. And there is also a problem that the signal may be lost and it cannot play a limiting role, resulting in equipment collision damage.
[0006] Therefore, we make improvements and propose a chain buffer limiter. Summary of the Utility Model
[0007] Aiming at the deficiencies of the prior art, the utility model provides a chain buffer limiter, which solves the problems mentioned in the background art.
[0008] To achieve the above-mentioned utility model purpose, the utility model provides the following technical solutions:

[0010] Specifically, this application is as follows:
[0011] It includes a fixed cylinder. One side surface of the fixed cylinder is fixedly installed with a mounting plate. A sliding rod is arranged inside the fixed cylinder, and a buffer mechanism is arranged between the sliding rod and the fixed cylinder.

An alarm is fixedly installed on one side surface of the mounting plate;
[0012] The buffer mechanism includes a sliding plate which is slidably connected inside the fixed cylinder. The sliding plate is fixedly connected to the sliding rod, and a first buffer spring is fixedly installed between the surface of the sliding plate and the mounting plate.

[0014] As a preferred technical solution of the present application, the first mounting mechanism includes a fixed box which is fixedly installed at the bottom of the fixed cylinder. A sliding block is slidably connected inside the fixed box, and a first connecting spring is fixedly installed between the sliding block and the bottom of the fixed box. The upper end of the sliding block is arranged in a hemispherical shape.
[0015] As a preferred technical solution of the present application, a fixed rod is fixedly installed at the bottom of the fixed box, and a first pressure sensor is fixedly installed on the upper end surface of the fixed rod.

A connecting rod is slidably connected inside the connecting cylinder, and a second connecting spring is fixedly installed between one side surface of the connecting rod and the connecting cylinder.

[0017] As a preferred technical solution of the present application, both between the first pressure sensor and the alarm and between the second pressure sensor and the alarm are connected by wires.

[0019] Compared with the prior art, the beneficial effects of the present utility model:
[0020] In the solution of the present application:
[0021] 1. By setting the buffer mechanism, the first mounting mechanism and the second mounting mechanism, the functions of two existing limiters can be integrated. It can not only prevent collision but also play a role in interlocking parking;
[0022] 2. Through the first pressure sensor provided, the device can emit a first alarm signal, enabling the operator to make timely adjustments. If the operator fails to operate in a timely manner, a stop signal will be emitted when continuously compressed for another stroke.

The newly added early warning and notification function (if conditions permit, this function can be changed to an automatic steering command, which can cooperate with the automatic stacking program to avoid downtime), significantly reducing the number of stops and avoiding the impact of stops on production;
[0023] 3. The elastic device itself changes the hard collision to buffer speed limit, which can better protect the equipment body. Brief Description of the Drawings

In addition, terms such as "first" and "second" are only used for descriptive distinction and cannot be understood as indicating or implying relative importance.
[0036] To solve the technical problems in the background art, the following chain buffer limiter is provided:
[0037] Combined with Figure 1 - Figure 5 As shown, a chain buffer limiter provided by the present utility model includes a fixed cylinder 1. A mounting plate 2 is fixedly installed on one side surface of the fixed cylinder 1. A sliding rod 3 is arranged inside the fixed cylinder 1. A buffer mechanism 4 is arranged between the sliding rod 3 and the fixed cylinder 1. A first mounting mechanism 5 is fixedly installed on the outer side surface of the fixed cylinder 1. A second mounting mechanism 6 is arranged inside the fixed cylinder 1. An alarm 7 is fixedly installed on one side surface of the mounting plate 2. The buffer mechanism 4 includes a sliding plate 401. The sliding plate 401 is slidably connected inside the fixed cylinder 1. The sliding plate 401 is fixedly connected to the sliding rod 3. A first buffer spring 402 is fixedly installed between the surface of the sliding plate 401 and the mounting plate 2. A connecting plate 403 is fixedly installed on the other end surface of the sliding rod 3. A buffer pad 404 is fixedly installed on the other side surface of the connecting plate 403.
[0038] In this embodiment: When the device uses the limiter, it will first come into contact with the buffer pad 404 on the surface of the connecting plate 403. The buffer pad 404 plays a buffering role and drives the connecting plate 403, the sliding rod 3, and the sliding plate 401 to slide. When the sliding plate 401 slides within the fixed cylinder 1, it will squeeze the first buffer spring 402, causing the first buffer spring 402 to deform. Through the elastic force of the first buffer spring 402 itself, it plays a role in buffering and isolating the sliding plate 401, the sliding rod 3, and the connecting plate 403.
[0039] As a preferred embodiment, a second buffer spring 405 is sleeved outside the sliding rod 3, and the second buffer spring 405 is fixedly installed between the connecting plate 403 and the fixed cylinder 1.
[0040] In this embodiment: While the connecting plate 403 and the sliding rod 3 are moving, the connecting plate 403 will simultaneously squeeze the second buffer spring 405 on its surface. Through the elastic force of the second buffer spring 405 itself, in cooperation with the first buffer spring 402, the buffering effect on the device is improved.
[0041] As Figure 2 - Figure 4 shown, on the basis of the above embodiment, in order to enable the interlocking buffer limiter to make the device emit an alarm signal, the following design is given in this embodiment:
[0042] As a preferred embodiment, the first installation mechanism 5 includes a fixed box 501, and the fixed box 501 is fixedly installed at the bottom of the fixed cylinder 1. A sliding block 502 is slidably connected inside the fixed box 501, and a first connecting spring 503 is fixedly installed between the sliding block 502 and the bottom of the fixed box 501. The upper end of the sliding block 502 is arranged in a hemispherical shape. A fixed rod 504 is fixedly installed at the bottom of the fixed box 501, and a first pressure sensor 505 is fixedly installed on the surface of the upper end of the fixed rod 504
[0043] In this embodiment: When the sliding plate 401 slides inside the fixed cylinder 1, it will squeeze the sliding block 502 inside the fixed box 501, causing the sliding block 502 to drive the first connecting spring 503 to deform. The sliding block 502 will squeeze the first pressure sensor 505 on the surface of the fixed rod 504, and an alarm signal and a steering signal will be sent through the alarm 7 to remind the operator to make timely adjustments.
[0044] As Figure 2 - Figure 5 shown, on the basis of the above embodiment, in order to enable the interlocking buffer limiter to make the device emit a driving signal, the following design is given in this embodiment:
[0045] As a preferred embodiment, the second mounting mechanism 6 includes a connecting cylinder 601, and the connecting cylinder 601 is fixedly mounted on one side surface of the mounting plate 2. A connecting rod 602 is slidably connected inside the connecting cylinder 601, and a second connecting spring 603 is fixedly mounted between one side surface of the connecting rod 602 and the connecting cylinder 601. A second pressure sensor 604 is fixedly mounted on the other end surface of the connecting rod 602.
[0046] In this embodiment: If the operator fails to operate in time, the sliding plate 401 continues to be compressed for a certain stroke. When the sliding plate 401 contacts the second pressure sensor 604 on the surface of the connecting rod 602, a parking signal will be sent through the alarm 7.
[0047] When the sliding plate 401 presses the second pressure sensor 604, it will drive the connecting rod 602 to slide inside the connecting cylinder 601 and deform the second connecting spring 603. The elastic force of the second connecting spring 603 itself can be used to buffer the connecting rod 602 and the second pressure sensor 604, preventing the second pressure sensor 604 from being damaged by extrusion.
[0048] As a preferred embodiment, both between the first pressure sensor 505 and the alarm 7 and between the second pressure sensor 604 and the alarm 7 are connected by wires.
[0049] In this embodiment: When the first pressure sensor 505 and the second pressure sensor 604 are contacted, an alarm signal and a parking signal can be sent through the alarm 7.
[0050] As Figure 1 - Figure 3 shown, on the basis of the above embodiment, in order to make the interlocking buffer limiter facilitate the installation of the limiter, the following design is given in this embodiment:
[0051] As a preferred embodiment, four mounting holes 8 are evenly formed on the surface of the mounting plate 2, and mounting screws 9 are arranged inside the mounting holes 8.
[0052] In this embodiment: The limiter can be fixedly installed by inserting the screw 9 into the mounting hole 8.
[0053] Specifically, the working principle of this solution is as follows:
[0054] During use, the device will come into contact with the buffer pad 404 on the surface of the connecting plate 403, and the buffer pad 404 will play a buffering role, driving the connecting plate 403, the sliding rod 3, and the sliding plate 401 to slide. When the sliding plate 401 slides within the fixed cylinder 1, it will squeeze the first buffer spring 402, causing the first buffer spring 402 to deform. Through the elastic force of the first buffer spring 402 itself, it plays a role in buffering and isolating the sliding plate 401, the sliding rod 3, and the connecting plate 403. The connecting plate 403 will simultaneously squeeze the second buffer spring 405 on its surface. Through the elastic force of the second buffer spring 405 itself, in cooperation with the first buffer spring 402, it improves the buffering effect on the device and plays an anti-collision role.
[0055] When the sliding plate 401 slides inside the fixed cylinder 1, it will squeeze the sliding block 502 inside the fixed box 501, causing the sliding block 502 to drive the first connecting spring 503 to deform. The sliding block 502 will squeeze the first pressure sensor 505 on the surface of the fixed rod 504, and send an alarm signal and a steering signal through the alarm 7 to remind the operator to adjust in time. If the operator fails to operate in time, the sliding plate 401 will continue to compress for a certain distance. When the sliding plate 401 comes into contact with the second pressure sensor 604 on the surface of the connecting rod 602, it will send a stop signal through the alarm 7. The above is the working process of the entire device, and the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
