[0023] In the following, terms such as "first", "second", etc. are used to describe the elements of the present application. These terms are only used to distinguish the various elements, and are not used to limit the nature, order or number of these elements. The terms "including" and "having" are used to express an open-ended inclusive meaning, and mean that there may be additional elements / components in addition to the listed elements / components.

[0024] Figure 1 and Figure 2 FIG. 2 shows a hose protective cover for engineering machinery according to an embodiment of the utility model. Engineering machinery generally has a hose 2 for connecting two adjacent devices. Figure 1 and Figure 2 As shown, the hose protective cover according to this embodiment includes a flexible protective cover body 1 and at least one fixed drawstring 3. The protective cover body 1 is a slender hollow cylindrical structure with open ends. The protective cover body 1 is made of a flexible material such as nylon. The protective cover body can be supported by cutting of the nylon cover, and the cut end edge is sealed by locking edge or other methods to prevent material wear or slippage and deformation. The hose 2 passes through the middle of the hollow protective cover body 1, thereby wrapping the hose 2 through the protective cover body 1. Optionally, Figure 1 It is shown that the protective cover body 1 only covers one hose 2 passing through it. In some other embodiments, when more than two hoses 2 pass through the hollow interior of the protective cover body 1, all the hoses 2 passing through the hollow interior can still be covered by the protective cover body 1.

[0025] Figure 1 In the illustrated embodiment, the fixing strap 3 is only arranged on the right side of the protective cover body 1, and the first end ( Figure 1 The left end shown in the figure) is connected to the protective sleeve body 1 (for example, the right end thereof) (for example, by sewing). The second end of the fixing strap 3 ( Figure 1 The right end of the fixing strap 3 is provided with a fastening structure for fastening the second end of the fixing strap to the frame of the engineering machine. In the embodiment shown, the fastening structure is designed as an opening 31. After the fastener passes through the opening 31, the second end of the fixing strap 3 can be fixed to the frame of the engineering machine. Figure 3 The corresponding position of the frame 10 of the construction machine shown (see Figure 3 For example, the frame 10 is provided with a through hole at a corresponding position of the hose 2 corresponding to the end portion where the fixing strap 3 is installed, and the bolt passes through the opening 31 and the through hole and then optionally passes through a gasket, and then is fastened by a nut. This prevents displacement between the protective cover body 1 and the hose 2.

[0026] It is understandable that the fastening structure may also be designed to include fastening bolts. Thus, the fastening bolts on the ends of the fixed drawstrings are directly inserted into corresponding holes on the frame, thereby fixing the fixed drawstrings on the frame.

[0027] Since the fixed drawstring 3 is also made of materials such as nylon and has a certain flexibility, in order to increase the wear resistance and tear resistance of the fixed drawstring 3 at the opening 31, a locking ring 7 is sleeved on the inner side of the opening 31 of the fixed drawstring 3. The locking ring is made of metal material. Specifically, the fixed drawstring 3 has a first side surface and a second side surface arranged opposite to each other on both sides of the axial direction of the opening 31, and the locking ring 7 has a first ring portion and a second ring portion formed integrally. The first ring portion is in contact with the first side surface of the fixed drawstring 3 located at the opening 31 and is arranged along the periphery of the opening 31, and the second ring portion is in contact with the second side surface of the fixed drawstring 3 located at the opening 31 and is arranged along the periphery of the opening 31. In this way, the periphery of the opening 31 is wrapped between the first ring portion and the second ring portion. In this way, the wear resistance of the fixed drawstring 3 at the opening 31 is enhanced.

[0028] Continue to refer Figure 1 A reserved fixing hole 11 is provided on the outer side of the protective cover body 1. When the hose 2 is long or the middle section thereof needs to be supported, the reserved fixing hole 11 can be passed through by a supporting member (such as a sling 5), thereby limiting the supporting member at a corresponding position, such as a substantially middle position of the protective cover body 1 in the axial direction.

[0029] In an advantageous embodiment, the hose protective cover may further include a limiting belt 4. Both ends of the limiting belt 4 are connected to the outside of the protective cover body 1 by, for example, sewing, so that the middle portion of the limiting belt 4 and the corresponding section covered by the limiting belt 4 on the outside of the protective cover body 1 are combined to define the reserved fixing hole 11.

[0030] Continue to refer Figure 1 , the axial extension direction of the reserved fixing hole 11 extends in the up-down direction, and the longitudinal extension direction of the protective cover body 1 is in the left-right direction, which shows that the axial extension direction of the reserved fixing hole 11 is substantially perpendicular to the longitudinal extension direction of the protective cover body 1. Of course, in special cases (such as Figure 3 As shown in the figure, according to the support point position of the middle section of the hose 2 on the frame 10, the axial extension direction of the reserved fixing hole 11 can also be slightly inclined in the up and down direction, so that the extension direction of the supporting member (such as a sling) passing through the reserved fixing hole 11 can coincide with the axial extension direction of the reserved fixing hole 11.

[0031] The number of the reserved fixing holes 11 can be one or more, which can be determined according to the length of the protective sleeve body 1 or the hose 2. Figure 1 The hose 2 and the protective cover body 1 of a shorter length are shown, and it is only necessary to set a limiting belt 4 in the middle area of ​​the protective cover body 1 along its longitudinal direction to form a reserved fixing hole 11. Figure 2 The protective cover body 1 is shown to have a longer length, so a plurality of (for example Figure 2 The three (three) limiting bands 4 shown in the figure are provided to form a corresponding plurality of reserved fixing holes 11. It is understood that the reserved fixing holes can also be distributed at intervals in the circumferential direction of the protective sleeve body. According to the actual fixing requirements, specific reserved fixing holes arranged on the protective sleeve body can be selected.

[0032] According to a more preferred embodiment, reference Figure 1 As shown, the hose protective cover can also include a sling 5 as a supporting member. The sling 5 passes through the reserved fixing hole 11 and forms a closed loop connected end to end in a manner of embracing the hose, so that the part of the closed loop away from the protective cover body 1 can be directly sleeved or fixed to the corresponding position of the frame 10 of the engineering machinery, such as Figure 3 shown.

[0033] Continue to refer Figure 1 and Figure 3As shown, the hose protective cover may further include a hanging buckle 6. The hanging buckle may be made of metal material. The hanging buckle 6 is in the shape of a roughly isosceles triangle, and a long eyelet 61 extending along its bottom is provided at its bottom, and a through hole 62 is provided at its top near the top corner. After the sling 5 passes through the reserved fixing hole 11 and wraps around the outer periphery of the protective cover body 1 to simultaneously embrace the hose 2, it then passes through the eyelet 61 and connects the ends to form a closed loop. The fastener passes through the through hole 62, thereby connecting the hanging buckle 6 to the corresponding part of the frame 10 of the engineering machinery.

[0034] Optionally, the number of fixed drawstrings may be one or more. Figure 2 The hose protective cover shown in the figure shows that it can include a protective cover body 1, and a first fixing drawstring 8 and a second fixing drawstring 9 respectively arranged at two end sides of the protective cover body 1.

[0035] Specifically, the protective cover body 1 includes a first end on the right side and a second end on the left side. The first fixing strap 8 is arranged on the right side of the protective cover body 1. Figure 2 The left end shown in FIG. 1 is connected to the first end of the protective sleeve body 1 by sewing or riveting, and the second end ( Figure 2 The second fixing strap 9 is arranged on the left side of the protective sleeve body 1, and its first end ( Figure 2 The right end shown in FIG. 1 is connected to the first end of the protective sleeve body 1 by sewing or rivet, and the second end ( Figure 2 The left end of the protective cover body 1 is provided with an opening 31 with a locking edge ring 7. In this way, the two ends of the protective cover body 1 with a longer length can be fixed to the corresponding positions of the frame 10 of the engineering machinery, further preventing the protective cover body 1 from moving along the axial direction of the hose 2. The first end of the first fixing strap 8 and the first end of the second fixing strap 9 can be connected to the corresponding ends of the protective cover body at different azimuth positions of the protective cover body.

[0036] The utility model also provides an engineering machine, which may include a hose 2 and the above-mentioned hose protective sleeve sleeved on the outer periphery of the hose. Figure 1 The above-mentioned hose protection sleeve is shown to be placed on a hose 2 with a larger diameter.
