  The present invention relates to a hose protector. In particular, the present invention relates to a hose protector that covers a high-pressure hose and prevents high-pressure liquid (oil, water, etc.) leaking from the high-pressure hose from scattering.

  Conventionally, hydraulic systems are used in construction machines such as power shovels and forklifts, press machines, pressurizers, luggage elevators, and the like. This hydraulic system uses hydraulic pressure as the motive power for operation. A high-pressure fluid produced by a hydraulic pump is sent out by a high-pressure hose, and a piston or a hydraulic motor (generally referred to as an actuator generally) installed at a predetermined location. ) Is a power system that performs work.

In order to make it possible, it is also known to be formed of a transparent resin material.

  Here, the high-pressure hose has an operation characteristic that the high-pressure hose moves due to the action of a high-pressure fluid passing through the inside thereof. Specifically, when a pressure is applied to the fluid inside the high-pressure hose from a state where no pressure is applied, the high-pressure hose moves so as to jump up. Moreover, when the state which applies a pressure to the fluid inside a hose is continued, it will pulsate. As described above, when a movement that causes the high-pressure hose to spring up or a pulsation of the high-pressure hose occurs, the covering position of the hose protector that is covered on the high-pressure hose is gradually shifted.

  The present invention has been made to solve such problems, and effectively prevents the hose protector covering position on the high-pressure hose from shifting as the use position continues. It aims at providing the hose protector which can do.

Achieved by protector.

  Moreover, it is preferable to comprise so that the height of the convex part formed in one surface of the said sheet part may become higher than the height of the convex part formed in the other surface of the said sheet part.

  The sheet portion is preferably made of a transparent resin.

  The reinforcing member has a lattice-like mesh structure, and each mesh is arranged along the circumferential direction of the high-pressure hose so that one side of the mesh is arranged along the longitudinal direction of the high-pressure hose. You may comprise so that it may become shorter than the dimension of one side.

  Further, the cover body is formed in a rectangular shape in plan view, and a pair of engaging members that fix the pair of side edges are installed on a pair of side edges that are arranged to face each other. It is preferable.

  Further, it is preferable that the one engaging member is disposed on one surface of the cover body, and the other engaging member is disposed on the other surface of the cover body.

  Hereinafter, the hose protector 1 which concerns on this invention is demonstrated with reference to an accompanying drawing. Each figure is partially enlarged or reduced in order to facilitate understanding of the configuration. FIG. 1 is a schematic plan view of a hose protector 1 according to the present invention. As shown in the perspective view of FIG. 2, the hose protector 1 is used by winding and covering the surface of a high-pressure hose, and when a damaged portion such as a tear or a hole occurs in the high-pressure hose, It is a cover that functions as a protective cover for preventing a fluid such as water and water from flowing out (scattering) to the outside and protecting the high-pressure hose from external interference.

  As shown in FIG. 1, the hose protector 1 includes a cover main body 2 and a pair of engaging members 3. The cover body 2 is formed in a rectangular shape in plan view, and includes a sheet portion 21 made of a transparent resin and a reinforcing member 22 embedded in the sheet portion 21. The cover body 2 is a member that winds and covers the surface of the high-pressure hose, and is configured to have a strength that does not break by receiving the fluid ejected from the high-pressure hose. The seat portion 21 provided in the cover body 2 has a rectangular shape in plan view. As a material for forming the sheet portion 21, for example, polyvinyl chloride (PVC) can be suitably used. The sheet portion 21 may be formed using a transparent resin material other than polyvinyl chloride. Further, the reinforcing member 22 included in the cover body 2 is configured by a mesh body having a mesh structure. As shown in FIG. 1, the mesh shape may be a lattice shape in which the mesh shape is a rectangular shape, or may be configured to be a rhombus, a circle, or an ellipse. The reinforcing member 22 configured as a mesh-like body exists throughout the sheet portion 21, but a part of the reinforcing member 22 is omitted in FIGS. 1 and 2. In the present embodiment, for example, the reinforcing member 22 is formed using a thread material formed from polyester. Specifically, the reinforcing member 22 is configured as a mesh-like body having a mesh-like structure by knitting a thread material formed from polyester.

  Here, in FIG. 1, the mesh structure of the reinforcing member 22 is configured so that each mesh has a rectangular lattice shape. As for the mesh, the dimension of one side arranged along the longitudinal direction of the cover body 2 (the direction along the longitudinal direction of the high-pressure hose) is along the short direction of the cover body 2 (the direction along the circumferential direction of the high-pressure hose). It is preferable to configure as a rectangular shape that is shorter than the dimension of one side to be arranged. That is, with respect to the thread material forming the lattice-like mesh, the interval between the thread materials arranged along the longitudinal direction of the cover body 2 is larger than the interval between the thread materials arranged along the short direction of the cover body 2. It is preferable to form a lattice network so as to be in a dense state.

  In the hose protector 1 according to the present invention, as shown in an enlarged cross-sectional view of a schematic configuration main part of FIG. 3, a convex portion 23 based on a mesh-like reinforcing member 22 (a convex portion 23 based on a thread material constituting the reinforcing member 22). ) Are formed on one surface and the other surface of the sheet portion 21, respectively. In addition, the convex part 23 has a mesh-like form in planar view. Although the height dimension (H1, H2) of the convex part 23 based on the mesh-shaped reinforcement member 22 each formed in the one surface of the sheet | seat part 21 and the other surface is not specifically limited, For example, 0.1 mm or more 1 It is preferable to set it to about 0.0 mm or less. Further, the height H1 of the convex portion 23 formed on one surface of the sheet portion 21 may be configured to be higher than the height H2 of the convex portion 23 formed on the other surface of the sheet portion 21. Good. In addition, you may comprise so that the height of the convex part 23 formed in one surface of the sheet | seat part 21 and the height of the convex part 23 formed in the other surface of the sheet | seat part 21 may become the same. Needless to say.

  Here, the sheet portion 21 in which the mesh-like reinforcing member 22 is embedded is, for example, a mesh-like reinforcing member 22 placed on a transparent resin sheet material, and further a transparent resin sheet material placed thereon. After mounting, it can be formed by applying a heat press. At this time, the mesh-shaped reinforcing member 22 is appropriately set by appropriately setting the diameter of the thread material constituting the mesh-shaped reinforcing member 22 and the thickness dimensions of the transparent resin and the sheet material disposed above and below the reinforcing member 22. The cover main body 2 (sheet part 21) provided with the convex part 23 based on 22 on one surface and the other surface can be obtained. In addition, in order to configure the height of the convex portion 23 formed on one surface of the sheet portion 21 to be higher than the height of the convex portion 23 formed on the other surface of the sheet portion 21, for example, What is necessary is just to set so that the thickness dimension of each transparent resin-made sheet | seat material arrange | positioned at the upper and lower sides of the reinforcement member 22 may differ.

  Moreover, you may apply | coat the functional layer which has the function to cut an ultraviolet-ray on the surface of the cover main body 2. FIG. Alternatively, the transparent resin material forming the sheet material may be preliminarily mixed with a material having a function of cutting ultraviolet rays to form the sheet material, and the cover body 2 may be configured to have the ultraviolet ray cutting function.

  The pair of engaging members 3 included in the hose protector 1 are means for securely installing and fixing the hose protector 1 to the high-pressure hose, and each of the pair of side edge portions 25 and 26 arranged to face each other in the cover body 2. The engaging members 31 and 32 are provided on the front. Further, one of the pair of engaging members 3 is configured such that one engaging member 31 is disposed on one surface of the cover body 2 and the other engaging member 32 is disposed on the other surface of the cover body 2. It is preferable to do. The pair of engaging members 3 is not particularly limited as long as the hose protector 1 wound around the outer periphery of the high-pressure hose is configured not to fall off from the high-pressure hose, but the female surface fastener and the male surface fastener A pair of hook-and-loop fasteners can be suitably used. When such a hook-and-loop fastener is employed as the engaging member 3, it is preferable that a female-type hook-and-loop fastener is disposed on the front surface side of the cover body 2 and a male-type hook-and-loop fastener is disposed on the back surface side of the cover body 2. Moreover, it is preferable to comprise so that the joining area (engagement area) of a female surface fastener may become larger than the joining area (engagement area) of a male surface fastener.

  Moreover, as a pair of engaging member 3, a slide fastener and a hook button can also be employ | adopted instead of the above-mentioned hook-and-loop fastener. When the engagement member 3 is configured by a slide fastener, one of a pair of stringer tapes provided with meshing elements is installed on one side of a pair of side edge portions 25 and 26 arranged to face each other in the cover body 2, and the other A stringer tape is installed on the other side of the pair of side edge portions 25 and 26. Similarly, when the engaging means 3 is constituted by a hook button, a hook is installed on one side of a pair of side edge portions 25 and 26 arranged to face each other in the cover main body 2, and a button is installed on the other side. When the pair of engaging members 3 are configured by hook buttons, it is preferable to install a plurality of hook buttons at predetermined intervals in a direction along the side edge of the cover body 2. Moreover, when installing a hook in the one surface side (for example, surface side) of the cover main body 2, it is preferable to install a button in the other surface side (for example, back surface side) of the cover main body 2. FIG.

  As described above, the hose protector 1 according to the present invention has the convex portion 23 based on the mesh-like reinforcing member 22 formed on one surface and the other surface of the cover body 2. Even if the high pressure hose is covered and used continuously, it is possible to effectively prevent the hose protector 1 from being displaced in the covering position. Specifically, in the hose protector 1 coated on the high-pressure hose, the convex portion 23 formed on the surface of the cover body 2 comes into contact with the surface of the high-pressure hose, and the convex portion 23 is not formed. Compared with the cover body 2, the contact area with the surface of the high-pressure hose can be greatly reduced, and the frictional resistance between the cover body 2 and the high-pressure hose can be reduced. As a result, even if the high pressure hose moves up or pulsates, the hose protector 1 is prevented from moving along the surface of the high pressure hose due to the movement of the high pressure hose. It is possible to effectively prevent the hose protector 1 from being displaced in the covering position.

  Moreover, since the hose protector 1 according to the present invention has the convex portions 23 based on the mesh-like reinforcing member 22 formed on both surfaces of the cover main body 2, even if the hose protector 1 is covered with any surface facing the high-pressure hose side, The effect of preventing the displacement of the covering position of the hose protector 1 described above can be obtained. In other words, the hose protector 1 is continuously used by covering the hose protector 1 so that one surface side faces the high pressure hose, and the hose protector 1 is used even when the convex portion 23 is worn by friction with the high pressure hose. The hose protector 1 can be used for a long period of time in a state where the hose protector 1 has been prevented from being misaligned by covering the hose protector 1 with the other surface facing the high pressure hose. There is also an effect that it can be used over a wide range.

  Further, when the height of the convex portion 23 formed on one surface of the sheet portion 21 is configured to be higher than the height of the convex portion 23 formed on the other surface of the sheet portion 21, that is, When the height of the convex portion 23 formed on the surface of the other is different from the height of the convex portion 23 formed on the other surface, the convex portion 23 having a higher height contacts the surface of the high-pressure hose. The hose protector 1 can be used in two patterns, such as being installed in a direction, or installed in a direction in which the convex portion 23 having a lower height contacts the surface of the high-pressure hose. Thus, the user can select the surface (one surface or the other surface) of the hose protector 1 (cover body 2) facing the surface of the high-pressure hose according to the friction state between the hose protector 1 and the high-pressure hose surface. (Surface) can be selected and used. As an example of selection, when the high pressure hose jumps or pulsates severely, the hose protector 1 is placed so that the surface side of the cover body 2 on which the convex portion 23 having a higher height is opposed to the surface of the high pressure hose. Hose protector so that the surface side of the cover body 2 on which the convex portion 23 with the lower height is formed faces the surface of the high-pressure hose when the high-pressure hose is covered and the pulsation is not so severe. It can be used properly, such as covering 1.

  Moreover, since the hose protector 1 according to the present invention includes the sheet portion 21 made of a transparent resin, the surface condition of the high-pressure hose can be checked and the individual high-pressure hoses can be covered with the hose protector 1 covered with the high-pressure hose. It is possible to confirm the control number or the like that is given to the high-pressure hose surface and is printed on the surface of the high-pressure hose through the mesh portion, and it is possible to reduce labor when performing maintenance inspection.

  Moreover, since the transparent resin sheet portion 21 in which the reinforcing member 22 is embedded is employed as the cover body 2 as described above, the strength of the cover body 2 can be improved while maintaining the transparency. . As a result, a damaged portion such as a tear or a hole is generated in the high-pressure hose, and when the oil flows out from the damaged portion to the outside vigorously, the cover main body 2 does not cause damage such as tearing. Can be effectively suppressed.

  Further, since a mesh-like body is employed as the reinforcing member 22 and the mesh-like body exists in the entire area of the cover main body 2, the overall strength of the cover main body 2 can be improved. In particular, in the present embodiment, the reinforcing member 22 has a lattice-like mesh structure, and the thread material arranged along the longitudinal direction of the cover body 2 with respect to the yarn material forming the lattice-like mesh. However, since the lattice-like mesh is formed so as to be denser than the interval of the yarn materials arranged along the short direction of the cover body 2, the tube is wound around the high-pressure hose in a cylindrical shape. The intensity | strength with respect to the diameter expansion of the hose protector 1 made can be improved. That is, a damaged portion such as a tear or a hole is generated in the high-pressure hose, and oil flows out from the damaged portion to the outside, and the radial direction of the hose protector 1 (cover body 2) that covers the high-pressure hose is wound. Even when a large force that causes the cover body 2 to expand is generated, the cover body 2 can be effectively prevented from breaking.

  In addition, the cover body 2 is formed in a rectangular shape in plan view as described above, and the pair of side edge portions 25 and 26 are fixed to a pair of side edge portions 25 and 26 arranged to face each other. A pair of engaging members 3 are installed. By providing such a pair of engaging members 3, the installation work of the hose protector 1 with respect to the high pressure hose or the work of removing the hose protector 1 from the high pressure hose can be made easy.

  In addition, one engagement member 31 of the pair of engagement members 3 is arranged on one surface of the cover body 2, and the other engagement member 32 is arranged on the other surface of the cover body 2. Therefore, when the hose protector 1 is wound around the high-pressure hose and the hose protector 1 is installed and fixed on the high-pressure hose by the pair of engaging members 3, the pair of side edge portions 25 and 26 are clean. It becomes possible to make it the state which overlapped. As a result, it is possible to suppress an external object from being caught on the hose protector 1 wound around the high-pressure hose and to easily release the wound state of the hose protector 1.

  Further, in the pair of engaging members 3, when one engaging member 31 is configured as a female surface fastener and the other engaging member 32 is configured as a male surface fastener, the hose protector 1 is attached to and detached from the high pressure hose. It becomes possible to carry out very simply. Further, when the hose protector 1 is wound around and covered with another high-pressure hose having a different thickness by configuring the bonding area of the female surface fastener to be larger than the bonding area of the male surface fastener. Can also be supported.

  The hose protector 1 according to the present invention has been described above, but the specific configuration is not limited to the above embodiment. In the said embodiment, although the cover main body 2 is comprised so that the sheet | seat part 21 made from transparent resin may be provided, the sheet | seat part 21 does not need to be transparent and uses the opaque resin to which some coloring was given. May be configured. When the sheet portion 21 is made of an opaque resin material, the surface state of the high-pressure hose is inspected or the surface of the high-pressure hose is printed on the surface of the high-pressure hose while the hose protector 1 is covered with the high-pressure hose. However, since the convex portion 23 based on the mesh-like reinforcing member 22 is formed on one side and the other side, it is not possible to check with the high-pressure hose at the time of covering. Even if the frictional resistance is reduced and a movement or pulsation that causes the high pressure hose to jump up occurs, it is possible to effectively prevent the covering position of the hose protector 1 covered on the high pressure hose from shifting. .

  Moreover, in the said embodiment, although the hose protector 1 is comprised so that a pair of engaging member 3 may be provided, you may comprise the hose protector 1 without providing such an engaging member 3. FIG. When the hose protector 1 is configured without providing the engaging member 3, for example, after the hose protector 1 is wound around the outer periphery of the high pressure hose, a binding means such as a binding band is further wound so that the high pressure hose and the hose protector 1 are wound. May be fixed integrally.

  Moreover, in the said embodiment, although the cover main body 2 is comprised as a sheet shape of planar view rectangular shape and it is comprised so that the hose protector 1 can be installed around the outer peripheral surface of a high pressure hose, for example, FIG. As shown in the schematic configuration perspective view of FIG. 1, the hose protector 1 is configured to cover the surface of the high-pressure hose by inserting the high-pressure hose from one end side of the cover body 2 into a cylindrical shape. May be. In addition, both are fixed integrally using binding means, such as a binding band, so that the installation position of the hose protector 1 with respect to the high-pressure hose does not shift.

Moreover, although the longitudinal direction length of the 1st support piece 51 and the 2nd support piece 52 can be set suitably, it is preferable that it is comprised so that it may become the same as the longitudinal direction length of the cover main body 2, for example.

  On the mutually opposing surfaces of the first support piece 51 and the second support piece 52, a first surface fastener strip 71 and a second surface fastener strip 72 are provided, respectively. The first surface fastener strip 71 and the second surface fastener strip 72 are preferably configured as a form along the longitudinal direction of the first support piece 51 and the second support piece 52.

The first surface fastener strip 71 and the fourth surface fastener strip 74 constitute a pair of male and female surface fastener strips, and the second surface fastener strip 72 and the sixth surface fastener strip 76 are a pair of male and female surface fasteners. A band piece is constituted, and the third surface fastener band piece 73 and the fifth surface fastener band piece 75 constitute a pair of male and female surface fastener band pieces.

  Here, the longitudinal lengths of the pair of male and female hook-and-loop fastener strips are the longitudinal lengths of the first support piece 51, the second support piece 52, the third support piece 61, and the fourth support piece 62 (the cover body). (Length in the longitudinal direction of 2) is preferably configured to be substantially the same. Further, the hose protector 1 according to FIG. 12 includes a combination of a first surface fastener strip 71 and a fourth surface fastener strip 74 that constitute a pair of male and female surface fastener strips, a second surface fastener strip 72, and a second surface fastener strip 72. In the combination of the 6-surface fastener strip 76 and the combination of the third surface fastener strip 73 and the fifth surface fastener strip 75, the first surface fastener strip 71 and the fourth surface fastener strip 74 overlap. In a state where the second surface fastener strip 72 and the sixth surface fastener strip 76 are overlapped and engaged, the third surface fastener strip 73 and the fifth surface fastener strip are further engaged. In the state where 75 is overlapped and engaged, the high pressure hose Z is surrounded to form a cylindrical body, so when the first hook-and-loop fastener piece 71 is configured as a male type, The four-sided fastener strip 74 configured as a female, when configuring the first surface fastener strip 71 as the female type constitute a fourth surface fastener strips 74 as a male type. Similarly, when the second surface fastener strip 72 is configured as a male type, the sixth surface fastener strip 76 is configured as a female type, and when the first surface fastener strip 71 is configured as a female type. When the sixth surface fastener strip 76 is configured as a male type and the third surface fastener strip 73 is configured as a male type, the fifth surface fastener strip 75 is configured as a female type, When the strip 73 is configured as a female mold, the fifth surface fastener strip 75 is configured as a male mold.

  According to the hose protector 1 according to FIG. 9 described above, the first surface fastener strip 71 and the fourth surface fastener strip 74 are overlapped and engaged, and the second surface fastener strip 72 and Surrounding the high-pressure hose Z with the six surface fastener strips 76 overlapped and engaged, and further with the third surface fastener strips 73 and the fifth surface fastener strips 75 overlapped and engaged. Therefore, it is possible to connect and fix the end portions (side edge portions) of the hose protector 1 with a strength three times that of the conventional hose protector 1. Thereby, even if a high-pressure liquid scatters out of the high-pressure hose Z and a large force acts on the hose protector 1, the connection portion between the male and female hook-and-loop strips in the hose protector 1 is disconnected, and the hose protector is removed. It is possible to more effectively prevent the occurrence of a situation where 1 is dropped from the high pressure hose Z.

  Further, in the hose protector 1 according to FIG. 9, the first hook-and-loop strip is provided by the engagement portion between the third hook-and-loop fastener 73 and the fifth hook-and-loop fastener 75 and the presence of the second support piece 52. 71 and the fourth hook-and-loop fastener piece 74 and the second hook-and-loop fastener piece 72 and the sixth hook-and-loop fastener piece 76 with respect to external sand, dust, water, Since it is difficult for sunlight to enter, the first surface fastener strip 71, the second surface fastener strip 72, the fourth surface fastener strip 74, and the sixth surface fastener strip 76 are effectively deteriorated. It has a structure that can be suppressed, and the strength of connecting and fixing the end portions (side edge portions) of the cover body 2 can be maintained for a long period of time.
