[0022] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0023] like Figures 1 to 3 As shown, the hydraulic joint protection device of the embodiment of the utility model includes a first protective cover 1 and a first fastener 2. The first protective cover 1 is arranged on the outside of the hydraulic joint, and the first protective cover 1 is in contact with the column. The first fastener 2 is inserted into the first protective cover 1, and the first fastener 2 is connected to the hydraulic joint.

[0024] Specifically, Figure 1 and Figure 2 As shown, the rear end and the upper end of the first protective cover 1 have openings, the first protective cover 1 is arranged outside the hydraulic joint, and the rear end of the first protective cover 1 is in contact with the column, that is, the first protective cover 1 sets the hydraulic joint cover in an independent space, one end of the first fastener 2 extends into the first protective cover 1, and one end of the first fastener 2 is connected to the hydraulic joint, thereby realizing the fixation of the first protective cover 1, or the first fastener 2 is connected to the column.

[0025] The hydraulic joint protection device of the embodiment of the utility model is provided with a first protective cover 1 on the outside of the hydraulic joint. When the pipeline 7 falls off, the pipeline 7 hits the first protective cover 1, thereby avoiding or reducing the risk of the pipeline 7 flying onto personnel, thereby reducing the safety hazard caused by the falling off of the pipeline 7.

[0026] In some embodiments, the hydraulic joint protection device further includes a second protection cover 3, the second protection cover 3 is connected to the first protection cover 1, and the second protection cover 3 is disposed outside the pipeline 7 connected to the hydraulic joint.

[0027] Specifically, Figure 1 As shown, the lower end of the second protective cover 3 is connected to the upper end of the first protective cover 1, and the second protective cover 3 is arranged outside the pipeline 7 connected to the hydraulic joint.

[0028] It should be noted that, since the length of the pipeline 7 is relatively long, the second protective cover 3 may only protect a section of the pipeline 7 adjacent to the hydraulic joint.

[0029] By providing a second protective cover 3 on the outside of the pipeline 7, when the pipeline 7 falls off, the pipeline 7 hits the second protective cover 3, avoiding or reducing the risk of the pipeline 7 flying onto people, thereby reducing the safety hazard caused by the falling of the pipeline 7.

[0030] In some embodiments, the second protective cover 3 is movable in the height direction of the first protective cover 1 to extend or retract into the first protective cover 1 .

[0031] For example, the second protective cover 3 can be moved in the up and down directions to extend or retract the first protective cover 1 , and by adjusting the length of the second protective cover 3 extending from the first protective cover 1 , the length of the pipeline 7 covered by the second protective cover 3 can be adjusted.

[0032] It should be noted that the maximum protected length of the pipeline 7 is the sum of the length of the second protective cover 3 fully extended from the first protective cover 1 and the length of the portion of the pipeline 7 covered by the first protective cover 1. When the protection length needs to be further increased, the length of the second protective cover 3 needs to be increased.

[0033] By providing the second protective cover 3 that can move up and down, the cover length of the pipeline 7 can be adjusted to adapt to different hydraulic joints.

[0034] In some embodiments, the hydraulic joint protection device further includes a second fastener 4 , which is inserted into the second protective cover 3 , and one end of the second fastener 4 extending into the second protective cover 3 abuts against the pipeline 7 .

[0035] Specifically, Figure 1 As shown, one end of the second fastener 4 extends into the second protective cover 3, and the end of the second fastener 4 extending into the second protective cover 3 abuts against the outer wall surface of the pipeline 7. The second fastener 4 can be used to fix the pipeline 7 to prevent the pipeline 7 from flying away when it is separated from the hydraulic joint.

[0036] In some embodiments, the second protective cover 3 includes a cover body 31 and a guard plate 32 , the cover body 31 is connected to the guard plate 32 , the guard plate 32 extends into the first protective cover 1 , and the cover body 31 extends in a direction away from the first protective cover 1 .

[0037] Specifically, Figure 3 As shown, the guard plate 32 is located at the lower end of the cover body 31. The guard plate 32 is a flat plate. The guard plate 32 extends into the first protective cover 1, and the outer wall surface of the guard plate 32 contacts the inner wall surface of the first protective cover 1. The cover body 31 is arranged on the outside of the pipeline 7. The guard plate 32, the first protective cover 1 and the outer wall surface of the column form a relatively independent space, which can better protect the hydraulic joint. When the joint is separated from the pipeline 7, the pressure medium injection can reduce or avoid damage to personnel and external equipment.

[0038] Optionally, the cover body 31 and the guard plate 32 are integrally formed, which can improve the structural strength of the second protective cover 3 .

[0039] In some embodiments, the hydraulic joint protection device also includes a pressure sensor 8, which is disposed in the first protective cover 1 and is used to monitor the pressure in the first protective cover 1. When the hydraulic joint is separated from the pipeline 7, the pressure medium ejected from the hydraulic joint will enter the first protective cover 1, causing the pressure in the first protective cover 1 to increase. The pressure sensor 8 is used to monitor the pressure changes in the first protective cover 1 and transmit the data of the pressure changes to the controller and the alarm, which can provide an alarm for the operator to avoid or reduce safety hazards.

[0040] In some embodiments, the hydraulic joint protection device further includes a buffer pad 5 , which is coated on the outside of the pipeline 7 , is located in the second protective cover 3 , and is located between the second fastener 4 and the pipeline 7 .

[0041] Specifically, Figure 1As shown, the buffer pad 5 is wrapped around the outside of the pipeline 7, and the buffer pad 5 is located inside the second protective cover 3. The end of the second fastener 4 extending into the second protective cover 3 abuts against the buffer pad 5. The use of the buffer pad 5 can not only reduce the pressure of the second fastener 4 on the outer wall of the pipeline 7, but also increase the contact area between the pipeline 7 and the second protective cover 3, thereby improving the protective effect of the protective cover on the pipeline 7.

[0042] In some embodiments, the hydraulic joint protection device further includes a leakproof bag 6 , which is connected to an end of the first protective cover 1 away from the second protective cover 3 , and the leakproof bag 6 is in communication with the first protective cover 1 .

[0043] Specifically, Figure 1 As shown, the upper end of the leak-proof bag 6 is connected to the bottom of the first protective cover 1. When the hydraulic joint is separated from the pipeline 7, the pressure medium ejected from the hydraulic joint will enter the first protective cover 1. By setting up the leak-proof bag 6, the leaked pressure medium can be temporarily stored, thereby reducing the pollution caused by the leakage of the pressure medium to the outside world.

[0044] In some embodiments, the leak-proof bag 6 is detachably connected to the first protective cover 1 . For example, the leak-proof bag 6 can be connected to the first protective cover 1 by bolts or snap-fitting, so that the leak-proof bag 6 can be easily replaced.
