Description

Technical Field

[0001] The utility model relates to the technical field of hose anti - detachment, in particular to a hose anti - detachment protection device. Background Technique

[0002] The hose anti - detachment structure refers to using special structures and devices when connecting hoses to prevent the hose from detaching from the pipe orifice due to external forces during use, thereby ensuring normal use, and is often applied to high - pressure hydraulic pipelines. In certain specific scenarios, such as in mining areas, due to the instability and intermittent impact of mine pressure, the hydraulic cylinder will bear a large instantaneous pressure, and the hose joint is prone to accidental detachment, which may cause whip - lashing injuries to the staff on the pedestrian passage and the operating platform or splashing injuries of high - pressure liquid.

[0003] The traditional anti - detachment structure is to install a safety rope, with one end connected to the hose of the hose assembly and the other end passing through a U - shaped clamp for connection or connected to the return pipe of the hose assembly. It effectively solves the safety hazard caused by the accidental detachment of the hose joint. However, it still has deficiencies:

[0004] Firstly, the existing hose anti - detachment devices usually lack an effective linkage traction structure. When the hose joint accidentally detaches, it fails to effectively restrain the hose, resulting in the hose possibly moving violently in a high - pressure environment, posing a serious threat to personnel and surrounding equipment.

[0005] Secondly, the existing hose anti - detachment devices lack a shock - absorbing mechanism at the hose connection, resulting in the hose being unable to effectively absorb and disperse the impact force when subjected to impact or vibration, increasing the risk of joint loosening and further exacerbating the safety hazard.

[0006] Therefore, there is an urgent need to design a hose anti - detachment protection device that can solve the above - mentioned technical problems. Content of the Utility Model

[0007] Aiming at the problems mentioned in the background technique, the purpose of the utility model is to provide a hose anti - detachment protection device to solve the problems mentioned in the background technique.

[0008] To achieve the above purpose, the utility model mainly provides the following technical solutions:

[0009] A hose anti - detachment protection device includes a ring body, and also includes:

[0010] A linkage traction mechanism and a shock - absorbing mechanism; where:

[0011] The linkage traction mechanism includes a safety ring arranged on the outer side of the ring body;

[0012] The shock - absorbing mechanism includes a shock - absorbing ring movably connected to the inner side of the ring body. There are clamping members arranged on the front and rear sides of the outer wall of the shock - absorbing ring, and a plurality of shock - absorbing springs are arranged between the two clamping members.

[0013] Furthermore, the safety ring is fixedly installed at the top outside of the ring body.

[0014] Furthermore, the ring body is divided into a movable half-ring and a fixed half-ring. Card slots are provided on the front and rear sides of the inner wall of the ring body, and a shock-absorbing groove is provided between the two card slots.

[0015] Furthermore, the shock-absorbing ring is of a semi-circular structure and is respectively movably installed inside the movable half-ring and the fixed half-ring. The clamping member is clamped and connected to the card slot, and the spring is movably arranged in the shock-absorbing groove.

[0016] Furthermore, a locking arm a is provided at the left end of the movable half-ring, and a locking groove a is provided at the left end of the locking arm a; a hinge rod is provided at the right end of the movable half-ring, and a rotating groove a is provided at the lower part of the hinge rod.

[0017] Furthermore, a locking arm b is provided at the left end of the fixed half-ring, a locking groove b is provided at the left end of the locking arm b, and a rotating shaft b is provided in the locking groove; a hinge groove is provided at the right end of the fixed half-ring, and a rotating shaft a is provided in the hinge groove.

[0018] Furthermore, a locking screw is provided at the right end of the ring body, and a rotating groove b is provided at the lower end of the locking screw; a locking nut is provided at the upper part of the locking screw, and a through hole is provided in the middle of the locking nut.

[0019] Furthermore, the ring body, the shock-absorbing ring and the locking screw are all made of high-strength corrosion-resistant materials. Compared with the prior art, the beneficial effects produced by the present utility model are mainly reflected in:

[0020] First of all, compared with the existing hose anti-disconnection device, there is a lack of effective restraint when the joint comes off. To solve this problem, a hose anti-disconnection protection device of the present utility model adopts a linkage traction mechanism, adds a safety ring outside the ring body, and connects the anti-disconnection device with a fixed facility through a safety rope, which can effectively limit the movement range of the hose when the joint accidentally pops off, avoid the harm caused by the high-pressure hose to personnel and other equipment, and significantly improve the working safety.

[0021] Secondly, compared with the existing hose anti-disconnection device, there is a lack of effective shock absorption ability, resulting in the easy disconnection of the joint when the hose is impacted. To solve this problem, a hose anti-disconnection protection device of the present utility model adopts a shock-absorbing mechanism, adds a shock-absorbing ring inside the ring body, and is equipped with a plurality of shock-absorbing springs, which can effectively absorb the energy generated when the hose is vibrated or instantaneously impacted, and reduce the risk of the joint coming loose.

[0035] The following will further elaborate on the present application in combination with the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the relevant invention and do not limit the invention. Additionally, it should be noted that for the sake of convenience of description, only the parts related to the invention are shown in the drawings.

[0036] As Figures 1-4 shown, a hose anti - detachment protection device of the present invention includes a ring body 1, and further includes:

[0037] Linkage traction mechanism 2 and shock absorption mechanism 3; among which:

[0038] The linkage traction mechanism 2 includes a safety ring 21 arranged on the outer side of the ring body 1. The function of the safety ring 21 is to sleeved the safety rope 4. When the hose interface accidentally breaks off, the safety rope 4 can play a traction role in time, fix the hose within a controllable range, and prevent it from causing harm to the surrounding environment or operators.

[0039] The shock absorption mechanism 3 includes a shock absorption ring 31 movably connected to the inner side of the ring body 1. On the front and back sides of the outer wall of the shock absorption ring 31, there are clamping members 32. Between the two clamping members 32, there are a plurality of shock absorption springs 33. The shock absorption mechanism 3 is arranged on the inner side of the ring body 1. When the hose is subjected to an external impact, the shock absorption springs 33 can undergo elastic deformation to absorb part of the impact energy. The shock absorption mechanism 3 can reduce the force transmitted to the hose joint, reducing the risk of the hose joint falling off.

[0040] As Figure 1 、 2 shown in FIGS. 4, in this embodiment, the safety ring 21 is fixedly installed on the top of the outer side of the ring body 1. The safety ring 21 is used to sleeved the safety rope 4. Its installation position ensures that the safety rope 4 can form a tight connection with the anti-disconnection device. When the interface accidentally breaks off, the safety ring 21 and the safety rope 4 can work together. By connecting with an external fixing device, the movement range of the hose is restricted, avoiding possible accidents.

[0041] As Figure 3 shown in FIGS., in this embodiment, the ring body 1 is divided into a movable half-ring 11 and a fixed half-ring 12. The ring body 1 is composed of two parts, which is convenient for the opening, closing and installation of the device. On the front and back sides of the inner wall of the ring body 1, there are card slots 13.

Between the two card slots 13, there is a shock absorption groove 14. The shock absorption groove 14 is designed between the two card slots 13 on the inner wall of the ring body 1 for accommodating the shock absorption springs 33.

[0042] As Figure 3 shown in FIGS., in this embodiment, the shock absorption ring 31 is a semi-circular structure and is respectively movably installed on the inner sides of the movable half-ring 11 and the fixed half-ring 12 to ensure that the shock absorption mechanism 3 can adapt to the bending radius of the hose and closely adhere to the inner wall. The clamping members 32 are engaged with the card slots 13, so that the shock absorption ring 31 can be firmly fixed and has a certain flexibility, enabling it to move slightly when subjected to an external force to absorb vibrations. The springs are movably arranged in the shock absorption grooves 14, and can effectively disperse and absorb vibration energy.

[0043] As Figure 3As shown, in this embodiment, a locking arm a111 is provided at the left end of the movable half ring 11, and the locking arm a111 is used to realize the locking function of the movable half ring 11 and the fixed half ring 12. A locking groove a112 is provided at the left end of the locking arm a111, and the locking groove a112 is used to accommodate the upper half of the locking screw 126; a hinge rod 113 is provided at the right end of the movable half ring 11, and a rotation groove a114 is provided at the lower part of the hinge rod 113. The hinge rod 113 and the rotation groove a114 at its lower part ensure that the movable half ring 11 can rotate smoothly at the hinge to facilitate opening, closing and installation.

[0044] like Figure 3 As shown, in this embodiment, a locking arm b121 is provided at the left end of the fixed half ring 12, and the cooperation of the locking arm b121 and the locking arm a111 realizes the tight locking function of the movable half ring 11 and the fixed half ring 12. A locking groove b122 is provided at the left end of the locking arm b121, and the locking groove b122 provides space for the placement of the locking screw 126. A rotating shaft b123 is provided in the locking groove, and the rotating shaft b123 realizes the function of free rotation of the locking screw 126; a hinge groove 124 is provided at the right end of the fixed half ring 12, and the hinge groove 124 is used to accommodate the hinge rod 113. A rotating shaft a125 is provided in the hinge groove 124, and the rotating shaft a125 cooperates with the rotating groove a114 of the movable half ring 11 to ensure the free opening and closing rotation of the ring body 1.

[0045] like Figure 3 As shown, in this embodiment, a locking screw 126 is provided at the right end of the ring body 1, and the locking screw 126 is used to firmly lock the entire ring body 1. A rotation groove b127 is provided at the lower end of the locking screw 126, and the locking screw 126 cooperates with the rotating shaft b123 of the fixed half ring 12 through the rotation groove b127 to realize the fixing and rotation functions; a locking nut 128 is provided on the upper part of the locking screw 126, and the lower part of the locking nut 128 is a cylindrical hollow structure, which is threadedly connected to the locking screw 126, and the upper part is a block structure, which realizes the function of manual adjustment. A through hole 129 is provided in the middle part of the locking nut 128, and the through hole 129 and the cylindrical hollow structure at the lower part of the locking nut 128 pass through, providing a certain amount of activity space for the locking screw 126, ensuring that the locking screw 126 and the locking nut 128 can be completely locked.

[0046] In this embodiment, the ring body 1, the shock-absorbing ring 31 and the locking screw 126 are all made of high-strength corrosion-resistant materials. These materials can resist the erosion of liquids, chemicals and high-temperature environments, especially in high-pressure liquid pipeline systems. The use of these materials ensures the long-term safety and reliability of the device.

[0047] The working principle and usage process of this technical solution are as follows: During use, first rotate the locking nut 128 upward until the locking screw 126 can be rotated leftward to open the ring body 1, or directly unscrew the locking nut 128 to open the ring body 1. Then, place the ring body 1 on the hose interface. Next, through the cooperation of the locking arm a111 and the locking arm b121, use the locking screw 126 and the locking nut 128 to firmly lock the ring body 1 to ensure that the anti-disconnection device fits tightly against the hose interface. After locking, the safety ring 21 in the linkage traction mechanism 2 sleevs the safety rope 4, and the safety rope 4 connects multiple anti-disconnection devices to external fixed facilities. At the same time, multiple shock-absorbing springs 33 in the shock-absorbing mechanism 3 can absorb part of the energy when the hose is impacted or vibrated, reducing the impact force, thereby effectively reducing the risk of hose joint disconnection and further enhancing the protection function of the device.

[0048] The above further describes the present utility model in conjunction with the embodiments, but the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the purpose of the present utility model.
