Description

Technical Field

[0001] This utility model belongs to the field of tool technology, specifically relating to an operating handle for a high-temperature metal hose. Background Technology

[0002] In fields such as mobile heating and industrial fluid transportation, high-temperature metal hoses (such as stainless steel hoses for steam transportation) require frequent installation and disassembly. Currently, these operations are mainly performed manually: operators typically wear heat-resistant gloves, hold the hose body with both hands, and rely on physical coordination to align and tighten the interfaces. Due to the large diameter, heavy weight, and high rigidity of the hoses, and the often high-temperature and space-constrained working conditions, this method has become the standard practice for such operations.

[0003] However, the existing operating methods are labor-intensive, requiring operators to use their hands, arms, and even their whole body in coordination, which can easily lead to fatigue. They are also inefficient and time-consuming. At the same time, personnel are at risk of burns from contact with the high-temperature pipe. Existing auxiliary tools (such as ordinary gloves) are inadequate in terms of heat insulation, operational flexibility, and adaptability, making it difficult to improve operational efficiency while ensuring safety. Utility Model Content

[0004] The purpose of this invention is to provide an operating handle for high-temperature metal hoses to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An operating handle for a high-temperature metal hose, comprising:

[0007] The handle body is composed of two symmetrical frames, which are detachably connected by connectors to form a closed ring structure.

[0008] A fixing component for fixing the handle body to the outer wall of the metal hose;

[0009] The fixing component includes a metal clamp that is adapted to the outer diameter of the metal hose. The metal clamp is sleeved on the outer wall of the metal hose and locked in place by a locking member. The metal clamp is connected to the handle body.

[0010] Preferably, the inner diameter of the metal clamp is adjustable.

[0011] Preferably, a gasket is provided between the inner contact surfaces of the two frames.

[0012] Preferably, the frame is a corrosion-resistant stainless steel frame.

[0013] Preferably, the connector includes bolts and studs.

[0014] Preferably, one end of the metal clamp is movably connected to the other end via a hinge, and the locking element is a locking nut disposed at the other end of the metal clamp.

[0015] Preferably, the frame is either semi-circular or U-shaped.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] (1) The handle is securely installed on the outer wall of the hose by the metal clamp, so the operator does not need to directly contact the high temperature hose body, effectively eliminating the risk of burns; at the same time, the handle provides a stable force point for rotating the hose, and one person or two hands can easily apply force, reducing labor intensity and improving docking speed and accuracy, which is suitable for harsh working conditions such as frequent assembly and disassembly, limited space or high temperature and high pressure.

[0018] (2) The whole is made of common materials and standard parts such as high temperature resistant stainless steel, which are easy to process and manufacture, lightweight, corrosion resistant and long service life; by changing or adjusting the size of the clamp, it can be adapted to metal hoses of various pipe diameters, realizing one handle for multiple uses and having good versatility.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1:

[0025] Please see Figures 1-3 As shown, an operating handle for a high-temperature metal hose includes:

[0026] The handle body is composed of two symmetrical frames 1, which are detachably connected by connectors to form a closed ring structure.

[0027] The fixing component is used to secure the handle body to the outer wall of the metal hose;

[0028] The fixing component includes a metal clamp 5 that is adapted to the outer diameter of the metal hose. The metal clamp 5 is sleeved on the outer wall of the metal hose and locked in place by a locking member 6. The metal clamp 5 is connected to the handle body.

[0029] In one embodiment of this utility model, the inner diameter of the metal clamp 5 is adjustable, for example, for a hose in the range of DN25 to DN100.

[0030] In one embodiment of this utility model, a gasket 4 is provided between the inner contact surfaces of the two frames 1. The gasket is a strip-shaped gasket used to enhance the friction and structural stability when gripping. The gasket material can be rubber or stainless steel.

[0031] In one embodiment of this utility model, the frame 1 is a corrosion-resistant stainless steel frame, preferably 304 or 316L stainless steel, with a thickness of 2mm, and the overall handle weight is less than 0.2kg.

[0032] In one embodiment of this utility model, the connector includes bolts 2 and studs 3, which connect two symmetrical frames to form a closed handle.

[0033] In one embodiment of this utility model, one end of the metal clamp 5 is movably connected to the other end via a hinge, and the locking member 6 is a locking nut provided at the other end of the metal clamp 5. By tightening the locking nut, the clamp can be tightly fitted to the outer wall of the hose.

[0034] In one embodiment of this utility model, the frame 1 is either semi-circular or U-shaped, and the two symmetrical frames are joined together to form a ring structure that is easy to hold.

[0035] As can be seen from the above, when using it, take two symmetrical high-temperature resistant stainless steel frames 1. The frames are semi-circular or U-shaped, preferably made of 304 or 316L stainless steel, with a thickness of 2mm and an external dimension of approximately 130mm in length and 70mm in width.

[0036] A strip-shaped pad 4 is placed between the inner contact surfaces of the two frames. The pad can be made of rubber or metal to enhance the friction when gripping and improve structural stability. Then, bolts 2 and studs 3 are used to align and connect the two frames to form a closed ring handle structure for easy gripping.

[0037] Select a matching metal clamp 5 according to the outer diameter of the metal hose. For example, for a DN65 stainless steel hose with an outer diameter of about 80mm, select a metal clamp with an inner diameter that matches it. Open the metal clamp, put it on the outer wall of the metal hose, and move it along the hose axis to a suitable position 100mm to 300mm away from the end of the hose interface. One end of the metal clamp is movably connected to the other end through a hinge, and the other end is equipped with a locking nut. The initial fixation of the clamp tightness can be achieved by adjusting the locking nut.

[0038] Place the assembled handle body above or to the side of the metal clamp, and connect it to the clamp. A stable connection can be achieved by welding, snap-fitting or bolting. Then, use a tool to tighten the locking nut on the metal clamp, so that the clamp gradually tightens and fits tightly against the outer wall of the hose until the handle body cannot rotate or loosen relative to the hose, ensuring that it remains stable during operation.

[0039] After installation, the handle body can be held with one hand while the other hand is used to guide and connect the hose interface. By applying torque through the handle, the metal hose can be easily rotated to achieve threaded connection or quick coupling with the corresponding interface and lock. During operation, the stainless steel structure and clamp of the handle can effectively isolate the high temperature of the hose surface (applicable temperature >300℃), avoiding direct contact of the hands with the high-temperature hose body and preventing burns. In addition, since the handle provides a stable grip point and lever arm, it reduces the hand gripping force required to rotate the hose, allowing one person to complete the docking operation efficiently without the need for two hands.

[0040] When it is necessary to disassemble the hose or adjust the position of the handle, first loosen the locking nut, slightly loosen the metal clamp, move it along the hose axis to the desired position, and then tighten it again.

[0041] If used with hoses of different diameters, the inner diameter of the metal clamp can be replaced or adjusted. For example, using an adjustable clamp can achieve versatility with a single clamp.

[0042] Example 2:

[0043] This embodiment provides a dual-sided operating handle suitable for large-diameter pipes or applications requiring two-handed operation. Its basic structure is the same as that of Embodiment 1, with the main difference being the arrangement and connection structure of the handle.

[0044] In this embodiment, the operating handle includes two handle bodies, which are symmetrically installed on both sides of the metal hose by independent fixing components.

[0045] Each handle body is still composed of two symmetrical frames 1 connected by bolts 2, studs 3 and washers 4 to form a ring structure. The two handle bodies have the same structure and are both made of high temperature resistant stainless steel.

[0046] The fixing assembly includes two independent metal clamps 5, each corresponding to a handle body. The two metal clamps 5 are arranged approximately 180 degrees apart along the circumference of the hose, respectively fitted onto the outer wall of the metal hose at the same axial position or slightly offset, and locked in place by their respective locking nuts;

[0047] Optionally, the two metal clamps 5 can be connected to each other by a connecting bridge plate, which can be a metal strip, welded or bolted to the outside of the two clamps to enhance the stability of the overall structure and prevent the two handles from rotating relative to each other when under force.

[0048] As can be seen from the above, when using it, first, put the two metal clamps 5 on the outer wall of the metal hose respectively, adjust them to be on the same cross-sectional circumference 150mm to 250mm away from the end of the interface, and ensure that the two are symmetrical about the center of the hose; install the two handle bodies onto the corresponding metal clamps respectively, tighten the locking nuts, so that the clamps firmly hold the hose; the operator can hold the two handles with both hands on both sides of the hose at the same time, and rotate the hose in coordination like using a "steering wheel". This method is suitable for occasions with DN80 or above, heavy weight or higher docking torque requirements, which can provide better torque distribution and operation stability, further reduce the load on one arm, and prevent the hose from swaying during docking. When it is not necessary to operate on both sides, only one handle can be used for one-handed operation, and the other handle can be used as a counterweight or spare grip.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
