Description

Technical Field

[0001] This invention relates to the field of mobile heating safety protection technology, specifically to a safety saddle for mobile heating metal hoses. Background Technology

[0002] Mobile heating uses flexible metal hoses to temporarily connect fixed pipelines to the mobile heating vehicle. The hoses are typically 3-10 meters long. In case of valve misoperation, equipment failure, or abnormal pressure, high-pressure steam may leak from the end of the hose instantly. If the movable end of the hose is not effectively secured, the following serious consequences may occur: Impact from objects: The hose may violently swing like a whip under the reaction force of the steam, impacting surrounding personnel or equipment and causing serious injury or even death; High-temperature burns: Steam may spray directly into the operating area, with instantaneous temperatures reaching over 150°C, causing severe burns; Secondary accidents: Uncontrolled movement of the hose may knock down surrounding facilities, expanding the scope of the accident.

[0003] However, mobile heating is currently an emerging market, and traditional industrial hose fixing devices are usually flange-fixed or clamp-fixed, which have many defects, such as being unable to cope with sudden releases: conventional fixing methods only achieve static connection and do not consider the dynamic locking requirements under abnormal working conditions; lack of release guidance: there is no dedicated structure to guide the direction of steam release, which cannot avoid direct injury to personnel; and complex operation: most devices require tools to assist in installation, which does not meet the needs of mobile heating scenarios for quick connection and one-handed operation. Summary of the Invention

[0004] The purpose of this invention is to provide a safety saddle for mobile heating metal hoses to solve the problem of uncontrolled release of mobile heating metal hoses in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a safety saddle for a mobile heating metal hose, comprising:

[0006] The saddle mechanism and the limiting mechanism assembled inside the saddle mechanism, and the locking mechanism assembled on the periphery of the saddle mechanism;

[0007] The saddle mechanism includes a mounting base plate, a supporting vertical tube is fixedly connected to the top of the mounting base plate, and a placement groove is provided at the front end of the supporting vertical tube;

[0008] The limiting mechanism includes a movable ring buckle fixedly connected to the inner wall of the supporting vertical tube, and the movable ring buckle has a C-shaped groove inside;

[0009] The locking mechanism includes a first fixed seat fixedly connected to one side of the supporting vertical tube and a second fixed seat fixedly connected to the other side of the supporting vertical tube. A safety chain is suspended on one side of the first fixed seat, and a spring buckle is connected to the bottom of the safety chain. A second fixed ring corresponding to the spring buckle is installed through one side of the second fixed seat.

[0010] Furthermore, the placement groove is U-shaped, and the edges of the placement groove are rounded and chamfered.

[0011] Furthermore, a drain outlet is provided at the bottom front end of the supporting vertical pipe, and anchor bolt holes are provided at the four corners of the mounting base plate.

[0012] Furthermore, a welding positioning groove is provided at the front end of the supporting vertical tube, and an installation block extending into the welding positioning groove is fixedly connected to the front end of the movable ring buckle.

[0013] Furthermore, the first fixed seat and the safety chain are suspended and connected by a first fixed hanging ring, and the upper part of the C-shaped slot is a narrow slot and the lower part is a flared guide section.

[0014] Furthermore, the first fixing seat is fixed to the supporting vertical tube by a first fixing bolt, and the second fixing seat is fixed to the supporting vertical tube by a second fixing bolt.

[0015] Compared with existing technologies, this invention provides a safety saddle for mobile heating metal hoses. Through the cooperation of the saddle mechanism, limiting mechanism, and locking mechanism, an automatic locking mechanism can be achieved. The reaction force of steam release achieves self-locking by tightening as it is pulled. When the hose quick connector is subjected to an upward pulling force, the movable ring buckle and the inner wall of the supporting vertical pipe form a wedge-shaped locking structure to prevent the hose from coming off. The locking mechanism provides double protection. The safety chain and movable ring buckle form a mechanical redundancy system. Even if the movable ring buckle fails, the safety chain can limit the displacement range of the hose and prevent it from swinging. It enables quick one-handed operation. Through the flared guide section and the inclined surface design of the movable ring buckle, the operator only needs to insert the hose quick connector from top to bottom to complete the installation without tools. The direction of release can be controlled. Through the synergistic effect of the placement groove and the safety chain, the steam release direction is directed to the sky, reducing the risk of injury to people on the ground.

[0024] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0025] As attached Figure 1 To be continued Figure 5 As shown:

[0026] Example 1:

[0027] This invention provides a safety saddle for a mobile heating metal hose, comprising:

[0028] The saddle mechanism 1, the limiting mechanism 2 assembled inside the saddle mechanism 1, and the locking mechanism 3 assembled on the periphery of the saddle mechanism 1;

[0029] The saddle mechanism 1 includes a mounting base plate 12, and a support vertical tube 11 is fixedly connected to the top of the mounting base plate 12. The front end of the support vertical tube 11 is provided with a placement groove 15.

[0030] The limiting mechanism 2 includes a movable ring buckle 21 fixedly connected to the inner wall of the supporting vertical tube 11, and the movable ring buckle 21 has a C-shaped groove 23 inside;

[0031] The locking mechanism 3 includes a first fixed seat 31 fixedly connected to one side of the support vertical tube 11 and a second fixed seat 35 fixedly connected to the other side of the support vertical tube 11. A safety chain 33 is suspended on one side of the first fixed seat 31, and a spring buckle 34 is connected to the bottom of the safety chain 33. A second fixed hanging ring 36 corresponding to the spring buckle 34 is installed through one side of the second fixed seat 35.

[0032] As can be seen from the above, by fixing the saddle mechanism 1 in a suitable position through the mounting base plate 12 during use, a stable support is provided for the entire device, ensuring that the support vertical tube 11 remains vertical. The support vertical tube 11 is made of stainless steel round tube, and the placement groove 15 can form a snap-in channel for the hose quick connector. Placing the quick connector of the metal hose in the placement groove 15 can fit the hose quick connector well and avoid damage to it. The top of the support vertical tube 11 is provided with an inclined guide slope corresponding to the position of the placement groove 15, which guides the hose quick connector to automatically slide into the locking position.

[0033] After the hose quick connector is placed, the limiting mechanism 2 is used to initially limit its position. Since the movable ring buckle 21 is fixedly connected to the inner wall of the supporting vertical pipe 11, and the movable ring buckle 21 has a C-shaped groove 23 inside, the operator only needs to insert the hose quick connector from top to bottom. The quick connector will smoothly enter the C-shaped groove 23 to complete the initial installation and positioning. Positioning can be completed with one hand. When the steam release generates an upward reaction force, the quick connector moves upward and is locked by the C-shaped groove 23 to prevent it from coming out.

[0034] Subsequently, the locking mechanism 3 is used to further strengthen the fixation of the metal hose. The spring buckle 34 at the bottom of the safety chain 33 is fastened to the second fixed ring 36 on the side of the second fixed seat 35, so that the safety chain 33 can be placed horizontally at the top of the metal hose. The safety chain 33 and the movable ring buckle 21 form a mechanical redundancy system. When an abnormal situation occurs, such as valve misoperation, equipment failure or abnormal pressure, and high-pressure steam is released from the end of the hose instantly, if the movable ring buckle 21 fails, the safety chain 33 can limit the displacement range of the hose, prevent the hose from swinging violently like a "whip", and prevent the surrounding personnel or equipment from being hit by objects.

[0035] Meanwhile, when the hose quick connector is subjected to an upward pulling force, the movable ring buckle 21 and the inner wall of the supporting vertical pipe 11 form a wedge-shaped locking structure. The reaction force of steam release achieves a self-locking effect that tightens as it is pulled, which can effectively prevent the hose from coming off. In addition, the placement groove 15 and the safety chain 33 work together to guide the steam release direction to the sky, reducing the risk of personnel being burned by high temperature due to steam spraying directly into the operating area. It also reduces the possibility of the hose moving out of control and pulling down surrounding facilities, causing secondary accidents. This ensures that the entire safety saddle can operate stably and reliably under various working conditions, providing comprehensive safety protection for mobile heating metal hoses.

[0036] From the appendix Figure 2 It can be seen that the placement groove 15 is U-shaped and the edges of the placement groove 15 are rounded and chamfered.

[0037] As can be seen from the above, the U-shaped placement groove 15 can better fit the quick connector of the metal hose, making the quick connector more stable and less prone to shaking within the placement groove 15. The rounded corner design of the edges prevents the quick connector from being scratched by sharp edges during placement and removal, protects the surface integrity of the quick connector, extends its service life, and also makes the operation safer for the operator, reducing the risk of being cut by sharp edges.

[0038] For details, please refer to the appendix. Figure 1 As shown, a drain outlet 16 is provided at the bottom front end of the support vertical pipe 11, and anchor bolt holes 13 are provided at the four corners of the mounting base plate 12.

[0039] As can be seen from the above, the drain outlet 16 can promptly drain any condensate that may accumulate in the support vertical pipe 11, preventing water accumulation from corroding the saddle mechanism 1 and extending the service life of the saddle mechanism 1. Meanwhile, the anchor bolt holes 13 at the four corners of the mounting base plate 12 facilitate the use of anchor bolts to firmly fix the mounting base plate 12 to the ground, ensuring that the entire safety saddle will not shift during use and providing stable support for the metal hose.

[0040] For details, please refer to the appendix. Figure 2 As shown, a welding positioning groove 14 is provided at the front end of the supporting vertical tube 11, and an installation block 22 extending into the welding positioning groove 14 is fixedly connected to the front end of the movable ring buckle 21.

[0041] As can be seen from the above, the installation position of the movable ring buckle 21 on the support vertical pipe 11 can be accurately determined by the cooperation of the welding positioning groove 14 and the mounting block 22, ensuring the accuracy and stability of the installation. During welding, the installation block 22 is inserted into the welding positioning groove 14, which makes the welding more secure and enhances the connection strength between the movable ring buckle 21 and the support vertical pipe 11. This prevents the movable ring buckle 21 from loosening or shifting during use, thereby ensuring that the limiting mechanism 2 can function properly and effectively limit the quick connector of the metal hose.

[0042] Working principle: Under normal use, the mobile heating metal hose is placed in the placement groove 15 via the quick connector. The movable ring buckle 21 and the wedge-shaped locking structure on the inner wall of the supporting vertical pipe 11 are in the initial state, and the safety chain 33 is loose. When valve misoperation, equipment failure, or abnormal pressure occurs, high-pressure steam is released from the end of the hose. The steam reaction force causes the hose quick connector to be pulled upward. At this time, the quick connector moves upward and is locked by the C-shaped groove 23. The movable ring buckle 21 and the wedge-shaped locking structure on the inner wall of the supporting vertical pipe 11 use the reaction force to self-lock, preventing the hose from coming off. If the movable ring buckle 21 fails, the safety chain 33 comes into play. Because it is placed horizontally at the top of the metal hose, it is fastened to the second fixed lifting ring 36 by the spring buckle 34, which can limit the displacement range of the hose and avoid violent swinging. At the same time, the placement groove 15 and the safety chain 33 work together to guide the steam release direction to the sky, reducing the risk of personnel being burned by high temperature and reducing the possibility of the hose being out of control and pulling down surrounding facilities, causing secondary accidents. The condensate in the supporting vertical pipe 11 is discharged in time through the drain outlet 16 to prevent water accumulation from corroding the saddle mechanism 1.

[0043] Example 2:

[0044] Reference Appendix Figure 3 As shown, the first fixed seat 31 and the safety chain 33 are suspended and connected by the first fixed lifting ring 32. The upper part of the C-shaped slot 23 is a narrow slot, and the lower part is a flared guide section.

[0045] As can be seen from the above, the safety chain 33 can be flexibly suspended on the first fixed seat 31 through the connection method of the first fixed lifting ring 32. During use, the angle and position can be adjusted according to actual needs, which can better adapt to different installation environments and metal hose arrangements, ensuring that the safety chain 33 can effectively play its role in limiting hose displacement. The width of the narrow groove at the top of the C-shaped slot 23 is smaller than the diameter of the quick connector. When the steam release generates an upward reaction force, the quick connector moves upward and is locked by the narrow groove at the top of the clamp to prevent it from coming off.

[0046] Reference Appendix Figure 3 As shown, the first fixing seat 31 is fixed to the supporting vertical tube 11 by the first fixing bolt 37, and the second fixing seat 35 is fixed to the supporting vertical tube 11 by the second fixing bolt 38.

[0047] As can be seen from the above, the fixing method of the first fixing bolt 37 and the second fixing bolt 38 ensures the stability of the connection between the first fixing seat 31 and the second fixing seat 35 and the supporting vertical tube 11. The detachable connection method makes it convenient and quick to operate when it is necessary to maintain, replace parts or adjust the position of the locking mechanism 3. In actual use, when the safety chain 33, spring buckle 34 and other parts are damaged or need to be adjusted, it is only necessary to unscrew the corresponding fixing bolts to remove the relevant parts from the supporting vertical tube 11 for repair or replacement, which greatly improves the maintainability and practicality of the equipment.

[0048] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
