Description

Technical Field

[0001] This application relates to the technical field of mechanical support protection, and in particular to a support device for preventing gates from falling off. Background Technology

[0002] In the bicycle manufacturing industry, the quality and performance of the frame are crucial to the overall quality of the bicycle. Heat treatment of the frame, as an indispensable key process in bicycle manufacturing, plays a decisive role in improving the frame's strength, rigidity, and toughness. With the continuous development of the bicycle industry, the requirements for frame quality are increasing, and heat treatment processes are constantly being improved and optimized. Many bicycle manufacturers have established dedicated heat treatment workshops to ensure that the frames undergo more precise and effective heat treatment. This not only helps improve the overall quality of bicycles but also enhances the company's competitiveness in the market, driving the bicycle industry towards higher quality and higher efficiency.

[0003] In the daily production of bicycle frame heat treatment workshops, feeding and discharging are essential operational steps. To ensure normal production order and smooth material transportation, vertical gates are typically installed to control the entry and exit of materials. In the past, insufficient attention was paid to the safety protection of these vertical gates, and in most cases, their normal operation was ensured solely by the gate's own lifting and lowering control system. When feeding or discharging was required, operators would raise or lower the gate using the control system to facilitate material entry and exit. However, this conventional operating method primarily focused on the normal opening and closing functions of the gate, lacking effective countermeasures for potential abnormal situations, such as the gate suddenly collapsing.

[0004] The conventional control methods for vertical gates in the current technology have certain limitations and cannot effectively avoid the risk of the gate falling. Especially during the feeding or discharging process, if the gate's lifting control system malfunctions or is interfered with by other factors, the gate may suddenly fall, posing a serious safety threat to on-site operators and equipment, and failing to guarantee the personal safety of personnel. Utility Model Content

[0005] To overcome the above-mentioned technical problems, this application provides a support device for preventing gates from falling off.

[0006] The support device for preventing gates from falling down provided in this application adopts the following technical solution: A support device for preventing a gate from falling off includes a main frame and a folding mechanism. The main frame includes a load-bearing column, the top of which has a top contact surface for contacting the bottom of the gate body of a vertical gate. The side of the load-bearing column has a load-bearing platform. Each load-bearing platform is rotatably connected to the gate frame of the vertical gate through the folding mechanism. The main frame has a working position and an unfolded position. The main frame can rotate around the rotation axis of the folding mechanism to switch from the working position to the unfolded position or vice versa. When the main frame is in the working position, the position of the load-bearing column corresponds to the position of the gate body.

[0007] By adopting the above technical solution, during the entire process of feeding or discharging materials in the workshop, the main frame can rotate around the rotation axis of the folding mechanism to the working position. When the gate body of the vertical gate falls uncontrollably, the force-bearing column located below the gate body abuts against the gate body through the top contact surface, preventing the gate from falling, avoiding safety accidents, and ensuring the personal safety of personnel. After feeding or discharging materials is completed, the main frame can rotate around the rotation axis of the folding mechanism to the unfolded position, so that the gate body can fall and close normally.

[0008] Optionally, the number of force-bearing platforms is two, and the force-bearing platforms are spaced apart along the vertical direction.

[0009] By adopting the above technical solution, the two force-bearing platforms spaced apart in the vertical direction can make the connection between the main frame and the gate frame more stable, enhance the support stability of the support device for the vertical gate, and the two force-bearing platforms, as force-bearing points, can alleviate the material deformation caused by the instantaneous drop of the gate.

[0010] Optionally, the folding mechanism includes a rotating seat and a rotating shaft. The rotating seat is located on the side of the door frame away from the interior of the vertical gate. The rotating seat has a rotating groove extending in the vertical direction. The top end of the rotating shaft is fixedly connected to the bottom of the force-bearing platform, and the rotating shaft is rotatably connected to the rotating groove.

[0011] By adopting the above technical solution, the rotating shaft can rotate within the rotating groove of the rotating seat, allowing the main frame to rotate around the axis of the folding mechanism, thus switching the main frame between the working position and the unfolded position. When supporting a vertical gate is required, the main frame can be rotated from the unfolded position to the working position, aligning the load-bearing columns with the gate body to support the uncontrolled vertical gate, preventing it from falling and ensuring personnel safety; when not in use, the main frame can be switched to the unfolded position without affecting the normal use of the gate.

[0012] Optionally, the folding mechanism further includes an elastic element disposed in the rotating groove, one end of which abuts against the bottom of the rotating groove, and the other end of which abuts against the bottom end of the rotating shaft.

[0013] By adopting the above technical solution, when the gate body falls uncontrollably and contacts the top contact surface of the force-bearing column, the first impact is generated. At this time, the elastic element in the rotating groove is compressed, which hinders the gate body from falling until the bottom contact surface of the force-bearing column contacts the ground, generating the second impact. The elastic element decomposes the original one impact into two impacts, which enhances the impact resistance of the entire device and extends its service life.

[0014] Optionally, the bottom of the load-bearing column is provided with a bottom contact surface for contacting the ground, and both the top of the top contact surface and the bottom of the bottom contact surface are provided with shock-absorbing pads.

[0015] By adopting the above technical solution, the impact force on the ground and gate body can be reduced when the support device supports the gate, the vibration and noise caused by the impact can be reduced, and the stability and durability of the support device can be improved.

[0016] Optionally, the main frame is integrally formed from high-strength steel.

[0017] By adopting the above technical solutions, the overall strength and stability of the main frame are improved, which can better withstand the impact force when the vertical gate falls and extend the service life of the support device.

[0018] Optionally, the folding mechanism includes a locking element that fixes the force-bearing platform in the working position.

[0019] By adopting the above technical solutions, the load-bearing platform can be stably fixed in the working position, avoiding accidental rotation of the main frame, improving the reliability of the support device in preventing the gate from falling, and ensuring the personal safety of personnel during the feeding or discharging process.

[0020] Optionally, the locking component includes an insulating plate and a magnetic plate. The insulating plate is fixedly connected to the force-bearing column. When the main frame is in the working position, the insulating plate is located on the side of the force-bearing column near the vertical gate's slide groove. The magnetic plate is fixedly connected to the force-bearing column through the insulating plate. The side of the magnetic plate away from the insulating plate is used to abut against the inner wall of the slide groove.

[0021] By adopting the above technical solution, the locking device composed of an insulating plate and a magnetic plate can be used to firmly fix the force-bearing platform in the working position. The insulating plate can also play an insulating role, increasing the safety of use, and the magnetic plate abuts against the inner wall of the slide, further enhancing the fixing effect.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The top of the load-bearing columns of the main frame is provided with a top contact surface, which can contact the bottom of the gate body of the vertical gate in the working position to prevent the gate from falling and ensure the personal safety of personnel; 2. The main frame can rotate around the axis of rotation of the folding mechanism, switching between the working position and the unfolded position without affecting the normal lifting and lowering of the gate; 3. The main frame is integrally formed from high-strength steel, which can withstand the impact of the gate falling and ensure the reliability of the support device. Attached Figure Description

Detailed Implementation

[0026] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0027] This application discloses a support device for preventing a gate from falling down. It is applied to a vertical gate, which is a common technology in this field. Its structure will not be described in detail here.

[0028] like Figure 1 and Figure 2 As shown, the support device for preventing the gate from falling includes a main frame and a folding mechanism. The main frame is rotatably connected to the gate frame 11 of the vertical gate through the folding mechanism. The main frame can rotate around the rotation axis of the folding mechanism to switch between the working position and the unfolded position. When the main frame is in the working position, the position of the force-bearing column 1 corresponds to the position of the gate body 10. In this way, when there is a risk of the gate falling, the force-bearing column 1 can support the gate body 10 and prevent it from falling, thus ensuring the safety of personnel and equipment.

[0029] like Figure 1 and Figure 2As shown, specifically, the main frame includes a load-bearing column 1, which is the main load-bearing component of the main frame. The top of the load-bearing column 1 has a top contact surface 3 for contacting the bottom of the gate body 10 of the vertical gate. The top contact surface 3 is a planar structure with a flat construction, allowing for full contact with the bottom of the gate body 10 to evenly distribute the pressure of the gate body 10. The top contact surface 3 can be made of high-strength steel to ensure it can withstand significant pressure. A load-bearing platform 2 is provided on the side of the load-bearing column 1. The load-bearing platform 2 is used to connect with the folding mechanism, serving to transmit force and provide support. There are two load-bearing platforms 2, spaced apart vertically. This arrangement makes the main frame more stable during rotation and also better distributes the force. The load-bearing platform 2 is usually a flat plate structure, made of the same material as the load-bearing column 1. It can be made of high-strength steel and integrally formed with the load-bearing column 1. This integrally formed structure has high strength and stability, and can better withstand the impact force generated when the gate falls. High-strength steel has good toughness and fatigue resistance, and can maintain the integrity of the structure during long-term use.

[0030] like Figure 1 and Figure 2 As shown, the folding mechanism includes a rotating seat 5 and a rotating shaft 6. The rotating seat 5 is located on the side of the door frame 11 away from the interior of the vertical gate. Here, the interior of the vertical gate refers to the workshop interior where the vertical gate is installed. The function of the rotating seat 5 is to provide support and space for the rotating shaft 6 to rotate. The rotating seat 5 is a block structure with a rotating groove extending vertically inside. The shape of the rotating groove is adapted to the rotating shaft 6, ensuring that the rotating shaft 6 can rotate smoothly within it. The rotating seat 5 can be made of high-strength steel. The top of the rotating shaft 6 is fixedly connected to the bottom of the load-bearing platform 2, and the rotating shaft 6 is rotatably connected to the rotating groove, so that the main frame can rotate around the axis of the rotating shaft 6. The rotating shaft 6 is a cylindrical structure, and its material is the same as that of the rotating seat 5 to ensure the fit between the two and the smoothness of rotation. The connection between the rotating shaft 6 and the load-bearing platform 2 can be welded to ensure the strength of the connection.

[0031] like Figure 2 As shown, the folding mechanism also includes an elastic element 7, which is disposed within the rotating groove. One end of the elastic element 7 abuts against the bottom of the rotating groove, and the other end abuts against the bottom end of the rotating shaft 6. The elastic element 7 can be a spring. When the gate body 10 falls uncontrollably and contacts the top contact surface 3 of the force-bearing column 1, a first impact is generated. At this time, the elastic element 7 disposed within the rotating groove is compressed, hindering the gate body 10 from falling until the bottom contact surface 4 of the force-bearing column 1 contacts the ground, generating a second impact. The elastic element 7 decomposes the original single impact into two impacts, enhancing the impact resistance of the entire device and extending its service life.

[0032] like Figure 1 and Figure 2 As shown, the bottom of the load-bearing column 1 is provided with a bottom contact surface 4 for contacting the ground. The bottom contact surface 4 is also a planar structure, and its function is to prepare for full contact with the ground when the main frame is in the working position, providing stable support. The distance between the bottom contact surface 4 and the ground is less than the compression stroke of the elastic element 7 when the gate body 10 falls uncontrollably. The material and construction of the bottom contact surface 4 are similar to those of the top contact surface 3, and it can also be made of high-strength steel. Both the top of the top contact surface 3 and the bottom of the bottom contact surface 4 are provided with shock-absorbing pads, which can be made of elastic materials such as rubber. The function of the shock-absorbing pads is to buffer and absorb shock when the gate contacts the load-bearing column 1 and when the load-bearing column 1 contacts the ground, reducing the impact force on the gate body 10 and the ground. Rubber shock-absorbing pads have good elasticity and wear resistance, and can effectively absorb and disperse impact force. Other elastic materials such as silicone can also be used to make shock-absorbing pads.

[0033] like Figure 1 and Figure 2 As shown, the folding mechanism includes a locking element that fixes the force-bearing platform 2 in the working position. The locking element includes an insulating plate 8 and a magnetic plate 9. The insulating plate 8 is fixedly connected to the force-bearing column 1. When the main frame is in the working position, the insulating plate 8 is located on the side of the force-bearing column 1 closest to the vertical gate's slide groove 12. The insulating plate 8 serves to provide insulation and isolation. The insulating plate 8 can be made of insulating materials such as plastic, and its shape and size are designed according to actual needs. The magnetic plate 9 is fixedly connected to the force-bearing column 1 through the insulating plate 8. The side of the magnetic plate 9 away from the insulating plate 8 is used to abut against the inner wall of the slide groove 12. The magnetic plate 9 is magnetic and can generate an adsorption force with the inner wall of the slide groove 12, thereby fixing the main frame in the working position.

[0034] The implementation principle of a support device for preventing gate collapse according to an embodiment of this application is as follows: This support device, through the cooperation of a main frame and a folding mechanism, effectively supports and protects a vertical gate. The main frame can rotate around the axis of rotation of the folding mechanism, and can quickly switch from the unfolded position to the working position when needed, providing support for the gate. The top contact surface 3 and bottom contact surface 4 of the load-bearing column 1, as well as the shock-absorbing pads, effectively disperse and buffer the impact force generated when the gate collapses, reducing damage to equipment and the ground. The elastic element 7 in the folding mechanism makes the rotation of the main frame smoother and helps it return to its initial position. The locking element securely fixes the main frame in the working position, ensuring stable support when the gate collapses. Compared with the prior art, this support device improves the safety of vertical gates and effectively avoids the harm caused to personnel and equipment by gate collapse.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
