Description

Technical Field

[0001] This utility model relates to the field of engineering machinery technology, specifically to a hose clamping device and engineering machinery. Background Technology

[0002] Construction machinery typically employs numerous hydraulic circuits to control components such as the boom. These complex circuits often require a large number of hoses to deliver hydraulic fluid. Taking excavators, a common example in construction machinery, as an example, the excavator consists of a lower traveling mechanism and an upper slewing body. The working device, including the boom and boom hydraulic cylinder, is mounted on the slewing body. The boom hydraulic cylinder is connected to the hydraulic supply system on the lower traveling mechanism via hoses, forming the hydraulic circuit. During operation, the excavator often moves relative to the traveling mechanism and the upper slewing body. Therefore, hose clamping devices are typically used to hold multiple hoses together to ensure orderly distribution of the hoses in the hydraulic circuit and prevent interference between them during operation. Existing hose clamping devices are relatively complex in structure, making hose installation inconvenient and prone to hose loosening. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to propose a hose clamping device with a simple structure, which can facilitate the installation of hoses and make the hoses stable.

[0004] The second objective of this utility model is to propose an engineering machinery.

[0005] To achieve the first objective mentioned above, this utility model adopts the following technical solution:

[0006] The hose clamping device includes a flexible hose clamp, a rigid fixing plate, and connectors;

[0007] The flexible pipe clamp is provided with multiple clamp holes for flexible hoses to pass through and multiple slits. The multiple slits are set one-to-one with the multiple clamp holes. The slits penetrate from the upper surface of the flexible pipe clamp to its lower surface. One end of the slit is connected to the corresponding clamp hole, and the other end extends to the edge of the flexible pipe clamp.

[0008] A rigid fixing plate covers the upper surface of the flexible pipe clamp. A through hole is provided on the rigid fixing plate, and the projections of all the pipe clamp holes on the rigid fixing plate are located inside the through hole. A connector is used to connect the flexible pipe clamp and the rigid fixing plate together.

[0009] The rigid fixing plate is provided with a first connecting hole, and the flexible pipe clamp is provided with a second connecting hole. The connector is a connecting bolt that passes through the first connecting hole and the second connecting hole to fix the rigid fixing plate and the flexible pipe clamp together.

[0010] The flexible pipe clamp is provided with two or more second connection holes, and the two second connection holes are staggered along the circumference of the flexible pipe clamp.

[0011] Both the flexible pipe clamp and the rigid fixing plate are disc-shaped. Multiple pipe clamp holes are opened in the middle of the flexible pipe clamp, and through holes are opened in the middle of the rigid fixing plate. Multiple slits are arranged along the circumference of the flexible pipe clamp, and the part of the flexible pipe clamp located between two adjacent slits forms a deformable part.

[0012] The lower surface of the flexible pipe clamp is provided with a downward protruding boss, one end of the pipe clamp hole extends to the upper surface of the flexible pipe clamp, and the other end extends to the bottom surface of the boss.

[0013] The width of the slit is 0.3~1mm; the diameter of the clamp hole is 12~21mm.

[0014] To achieve the second objective mentioned above, this utility model adopts the following technical solution:

[0015] Construction machinery, including the aforementioned hose clamping device.

[0016] The beneficial effects of this utility model are as follows:

[0017] In this invention, each clamp hole on the flexible clamp is equipped with a slit extending to the edge of the flexible clamp. When inserting the flexible hose, the size of the clamp hole can be expanded by bending the flexible clamp, thus facilitating the passage of the hose through the clamp hole. After the rigid fixing plate and the flexible clamp are connected together by the connector, the rigid fixing plate can maintain the shape of the flexible clamp, thus ensuring that the flexible clamp can clamp the hose. This not only facilitates the installation of the hose but also prevents the hose from loosening, and the overall structure is relatively simple. Attached Figure Description

[0021] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments:

[0022] like Figure 1 , 2As shown in Figure 3, this utility model provides a hose clamping device suitable for engineering machinery such as loaders and excavators. The hose clamping device includes a flexible hose clamp 10, a rigid fixing plate 20, and a connector 30. The flexible hose clamp 10 is made of a deformable material such as rubber. The rigid fixing plate 20 can be made of steel plate cut according to a preset shape. The flexible hose clamp 10 is provided with multiple clamping holes 11 and multiple slits 12. The multiple clamping holes 11 are located in the inner area of ​​the flexible hose clamp 10. The multiple slits 12 are arranged one-to-one with the multiple clamping holes 11, and the slits 12 penetrate from the upper surface to the lower surface of the flexible hose clamp 10. One end of the slit 12 is connected to the corresponding clamping hole 11, and the other end extends to the edge of the flexible hose clamp 10. That is, the slit 12 forms an opening at the edge of the flexible hose clamp 10. The parts of the flexible hose clamp 10 located on both sides of the slit 12 are separated by the slit 12. A rigid fixing plate 20 covers the upper surface of the flexible pipe clamp 10. A through hole 21 is provided on the rigid fixing plate 20. The area covered by the through hole 21 is relatively large, so that the projection of all the pipe clamp holes 11 on the rigid fixing plate 20 is located inside the through hole 21. The connector 30 is used to fix the flexible pipe clamp 10 and the rigid fixing plate 20 together.

[0023] In use, the hose 40 is passed through the clamping hole 11 of the flexible hose clamp 10, and then all the hoses 40 are passed through the through hole 21 of the rigid fixing plate 20. Finally, the rigid fixing plate 20 is fixed to the upper surface of the flexible hose clamp 10 using the connector 30, and multiple hoses 40 are connected using the hose clamping device. In this utility model, since each clamping hole 11 on the flexible hose clamp 10 is provided with a slit extending to the edge of the flexible hose clamp 10, when inserting the hose 40, the size of the clamping hole 11 can be expanded by bending the flexible hose clamp 10, thereby facilitating the passage of the hose 40 through the clamping hole 11. After the rigid fixing plate 20 and the flexible hose clamp 10 are connected together by the connector 30, the rigid fixing plate 20 can play a shape-preserving role for the flexible hose clamp 10, thus ensuring that the flexible hose clamp 10 can clamp the hose 40. This not only facilitates the installation of the hose 40, but also prevents the hose 40 from loosening, and the overall structure is relatively simple.

[0024] The rigid fixing plate 20 is provided with a first connecting hole 22, and the flexible pipe clamp 10 is provided with a second connecting hole 13. The connecting member 30 is a connecting bolt that passes through the first connecting hole 22 and the second connecting hole 13. The connecting bolt is used to fix the flexible pipe clamp 10 and the rigid fixing plate 20 together. Of course, in other embodiments, the connecting member 30 is not necessarily a connecting bolt. It can be other connecting components, such as rivets, pins, etc. that pass through the first connecting hole 22 and the second connecting hole 13. Two or more connecting members 30 can be used to connect the rigid fixing plate 20 and the flexible pipe clamp 10 together to ensure that the rigid fixing plate 20 plays a better role in maintaining the shape of the flexible pipe clamp 10. In a preferred embodiment, the flexible pipe clamp 10 is provided with another second connecting hole 14. The second connecting hole 14 and the second connecting hole 13 are offset by a certain distance in the circumferential direction of the flexible pipe clamp 10, for example, the angle between them is 90°. The rigid fixing plate 20 and the flexible pipe clamp 10 can be connected together by aligning the second connecting hole 14 with the first connecting hole 22 and using a connecting bolt passing through the second connecting hole 14 and the first connecting hole 22. In this way, the mating angle between the rigid fixing plate 20 and the flexible pipe clamp 10 can be adjusted to adapt to the actual installation needs of the hose 40.

[0025] Both the flexible pipe clamp 10 and the rigid fixing plate 20 are disc-shaped. Multiple pipe clamp holes 11 are opened in the middle of the flexible pipe clamp 10, and through holes 20 are set in the middle of the rigid fixing plate 20. The shape of the through holes 20 can be set as a rectangle or the like to accommodate the arrangement of multiple pipe clamp holes 11, ensuring that the projection of multiple pipe clamp holes 11 on the rigid fixing plate 20 is located inside the through holes 20. Multiple slits 12 are arranged circumferentially along the flexible pipe clamp 10. The part of the flexible pipe clamp 10 located between two adjacent slits 12 forms a deformation part. During the insertion of the flexible pipe 40, the pipe clamp hole 11 can be deformed by bending the deformation part to expand the pipe clamp hole 11. The lower surface of the flexible pipe clamp 10 is provided with a downward protruding boss 15. One end of the pipe clamp hole 11 extends to the upper surface of the flexible pipe clamp 10 and the other end extends to the bottom surface of the boss 15. By providing the boss 15, the extension size of the pipe clamp hole 11 can be increased, thereby increasing the contact area between the flexible pipe clamp 10 and the hose 40 and further improving the stability of the hose 40 fixed on the hose clamping device.

[0026] The width of the aforementioned slit 12 is 0.3~1mm to ensure that the flexible pipe clamp 10 can deform sufficiently without excessively losing the strength of the flexible pipe clamp 10. The diameter of the pipe clamp hole is 12~21mm to accommodate hoses 40 of different sizes.

[0027] The engineering machinery of this utility model includes the above-mentioned hose clamping device. Other structures of the engineering machinery are the same as those in the prior art and will not be described in detail here.

[0028] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
