Description

Technical Field

[0001] The utility model relates to the technical field of pipeline protection devices, and particularly relates to a pipeline through-hole protection device. Background Art

[0002] When hydraulic oil pipeline is laid in earthmoving machinery such as excavators, it is often necessary to lay the pipeline from one space to another space. For example, the pilot handle needs to be connected to the pilot hydraulic hose that extends in from outside through the cab floor. Therefore, a through-hole for the pilot hydraulic hose must be provided on the floor. In the prior art, generally an oval hole is opened on the plate of the floor or wall panel that needs to pass through the hole. Then a rubber part is arranged along the edge of the oval hole. Then multiple pipelines are passed through one rubber part. Although the rubber part can reduce the friction between the pipeline and the edge of the oval hole, the following technical problems still exist in the actual use process:

[0003] (1) During the working process of earthmoving machinery, the vehicle body vibrates greatly. After multiple oil pipelines pass through an oval hole, the pipelines contact each other, and vibration wear between the pipelines is likely to occur.

[0004] (2) Generally, the rubber part is stuck on the oval hole by a rubber flange. During work, the hose will squeeze the rubber part back and forth. After long-term use, the flange part of the individual hole protection ring will surely be damaged, causing the hole protection ring to deform inward, resulting in no support in the middle of the pipeline through-hole protection rubber part, and finally the protection rubber part falls off. Content of the Utility Model

[0005] To achieve the above object, one or more embodiments of the utility model provide the following technical solutions.

[0006] The utility model provides a pipeline through-hole protection device, which includes a mounting plate. An oval hole is opened on the mounting plate. A protection box is installed in the oval hole. A plurality of wire harness through-holes are opened in the protection box. A plurality of openings are opened in the circumferential direction of the wire harness through-holes. Rubber columns are arranged between the wire harness through-holes. The protection box is split into an upper shell and a lower shell along the middle line of the protection box. The adjacent rubber columns in the upper shell are respectively provided with a first protrusion and a first groove. A second groove is arranged on the rubber column corresponding to the first protrusion and located in the lower shell. A second protrusion is arranged on the rubber column corresponding to the first groove and located in the lower shell.

[0007] Further, an elastic buckle is arranged on one side of the protection box. The protection box is stuck in the oval hole through the elastic buckle.

[0008] Further, the elastic buckle is a rubber frustum, and a part of the elastic buckle extends to the outside of the protection box.

[0009] Further, a retaining ring flange is arranged on the outer side of the protection box. The side wall of the retaining ring flange is attached to the side wall of the mounting plate.

[0010] Further set that the wire harness through - hole is a circular hole, and a plurality of wire harness through - holes are evenly distributed along the length direction of the protection box.

[0011] Further set that the diameter of the wire harness through - hole decreases successively along the length direction of the protection box.

[0012] Further set that the opening penetrates through the side wall of the protection box, and the opening is strip - shaped.

[0013] Further set that the cross - section of the first protrusion is triangular, and the cross - section of the second protrusion is triangular.

[0014] Further set that the cross - section of the first groove is triangular, and the cross - section of the second groove is triangular.

[0015] Further set that the protection box and the wire harness through - hole are made of rubber material.

[0016] The beneficial effects of the above - mentioned one or more technical solutions are as follows:

[0017] (1) An opening structure is added to the through - hole, which will be isolated by rubber columns, avoiding mutual wear between pipelines. While supporting and fixing the pipelines, it can adapt to more pipeline diameters.

[0018] (2) Rubber columns are arranged between the wire harness through - holes. The rubber columns serve as a support structure and are formed by splicing protrusions and grooves. The support structure composed of rubber columns, protrusions and grooves provides support in the width spacing of the retaining ring flange, enabling the originally unsupported through - hole protection rubber parts to obtain support, reducing the risk of falling off. While the retaining ring flange obtains support, the pipelines are isolated to avoid related wear. At the same time, the protection box is restricted on the side wall of the mounting plate through elastic buckles and the retaining ring flange, improving the installation stability of the protection box.

Specific implementation manner

[0028] The following combines with the accompanying drawings to illustrate the specific implementation manner of this embodiment.

[0029] A pipeline through-hole protection device, referring to Figure 2 、 Figure 3 And Figure 4 , includes a mounting plate 1. The mounting plate 1 is provided with a kidney-shaped hole 2. A protective box 3 is installed in the kidney-shaped hole 2. The protective box 3 is provided with a plurality of wire harness through-holes 4. A plurality of openings 13 are provided in the circumferential direction of the wire harness through-holes 4. Rubber columns 5 are arranged between the wire harness through-holes 4. The protective box 3 is split into an upper shell 31 and a lower shell 32 along the middle line. The rubber columns 5 adjacent to each other in the upper shell 31 are respectively provided with a first protrusion 6 and a first groove 7. A second groove 9 is provided on the rubber column 5 corresponding to the first protrusion 6 and located in the lower shell 32. A second protrusion 8 is provided on the rubber column 5 corresponding to the first groove 7 and located in the lower shell 32.

[0030] The pipeline through-hole protection device separates multiple wire harness through-holes 4 through rubber columns 5 in the middle. Referring to Figure 1 , compared with the existing rubber part 12, when the elastic buckle 10 is worn, the rubber column 5 can still provide support for the protective box 3, reducing the risk of the protective box 3 falling off. After the pipeline through-holes 4 are isolated from each other, interference and wear between pipelines are avoided. The pipeline through-hole has an opening structure, and one through-hole can adapt to various pipeline diameters.

[0031] An elastic buckle 10 is provided on one side of the protective box 3. The protective box 3 is clamped in the kidney-shaped hole 2 through the elastic buckle 10. The elastic buckle 10 is a rubber frustum. A part of the elastic buckle 10 extends to the outside of the protective box 3. A retaining ring flange 11 is provided on the outside of the protective box 3. The side wall of the retaining ring flange 11 fits against the side wall of the mounting plate 1. The area surrounded by the retaining ring flange 11 can completely cover the kidney-shaped hole 2. After the elastic buckle 10 of the protective box 3 is aligned with the kidney-shaped hole 2 and pressed in, since the distance between the outermost sides of the upper and lower elastic buckles 10 is greater than the width of the kidney-shaped hole 2, and the elastic buckle 10 is made of rubber material, when pressed into the kidney-shaped hole 2, a part of the elastic buckle 10 extending to the outside of the protective box 3 deforms until a part of the elastic buckle 10 extending to the outside of the protective box 3 passes through the subsequent kidney-shaped hole 2, and then the elastic buckle 10 resumes its original shape under the action of elastic force. Since the distance between the outermost sides of the upper and lower elastic buckles 10 is greater than the width of the kidney-shaped hole 2, at this time, the inner side wall of a part of the elastic buckle 10 extending to the outside of the protective box 3 is blocked on the side wall of the protective box 3.

[0032] The wire harness through-hole 4 is a circular hole. A number of wire harness through-holes 4 are evenly distributed along the length direction of the protective box 3. The diameter of the wire harness through-hole 4 decreases sequentially along the length direction of the protective box 3, and can adapt to more pipeline diameters.

[0033] The opening 13 penetrates the side wall of the protective box 3. The opening 13 is strip-shaped. The opening 13 structure of the through-hole increases the pipeline diameter adaptation range.

[0034] The cross-section of the first protrusion 6 is triangular, the cross-section of the second protrusion 8 is triangular, the cross-section of the first groove 7 is triangular, and the cross-section of the second groove 9 is triangular. The protective box 3 is divided into upper and lower parts. After the pipeline passes through the through-hole, the two parts are combined and then fixed in the kidney-shaped hole 2. The wedge-shaped structure formed by the first protrusion 6 and the second groove 9 and the first groove 7 and the second protrusion 8 can prevent misalignment when the two parts are fixed.

[0035] The protective box 3 and the wire harness through-hole 4 are made of rubber material. Rubber columns 5 are provided between the pipeline through-holes to prevent the pipelines from rubbing against each other. At the same time, the rubber material of the protective box 3 and the wire harness through-hole 4 can reduce friction.

[0036] When installing the upper shell 31 and the lower shell 32:

[0037] Insert the first protrusion 6 and the first groove 7 of the upper shell 31 into the second groove 9 and the second protrusion 8 of the lower shell 32 respectively. After insertion, the upper shell 31 and the lower shell 32 are spliced into the protective box 3. Subsequently, after the elastic buckle 10 of the protective box 3 is aligned with the kidney-shaped hole 2 and pressed in, the elastic buckle 10 deforms and then the elastic buckle 10 hooks on the side wall of the kidney-shaped hole 2.

[0038] Although the specific implementation manners of the present utility model have been described above in conjunction with the accompanying drawings, it is not a limitation on the protection scope of the present utility model. Those skilled in the art should understand that various modifications or deformations that can be made without creative efforts on the basis of the technical solution of the present utility model are still within the protection scope of the present utility model.
