Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic support mechanisms, in particular to an engineering hydraulic support mechanism. Background Art

[0002] The engineering hydraulic support mechanism is a mechanical device that uses the pressure transmission properties of liquid to support and move heavy objects. It supports or pushes the load through the force generated by the hydraulic cylinder and is widely used in various engineering machinery and industrial equipment. The hydraulic support mechanism uses a hydraulic system to control and adjust the support structure so that it can adapt to various geological conditions and construction requirements.

[0003] At present, most of the existing hydraulic support mechanisms are locked by hydraulic locks during use. However, the hydraulic locks themselves have certain leakage. After being placed for a period of time, if the hydraulic locks fail, the hydraulic push rods will fail, resulting in failure of the support function. There are certain risks, which affect the safety of the use of the hydraulic support mechanism. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that the hydraulic lock itself has certain leakage. After being placed for a period of time, if the hydraulic lock fails, it will cause the hydraulic push rod to fail, resulting in failure of the supporting function, which poses certain risks and affects the safety of the use of the hydraulic support mechanism. An engineering hydraulic support mechanism is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A hydraulic support mechanism for an engineering project comprises a base, an extension seat integrally formed on one side of the base, a hydraulic push rod rotatably connected to the top of the base, two connecting rods rotatably connected to the top of the base, and the top of the connecting rod is rotatably connected to the same support mechanism, the other end of the hydraulic push rod is rotatably connected to the support mechanism, two sliding grooves are provided on the top of the extension seat, and a guide rod is fixedly connected to the inner wall of the sliding groove, a spring is sleeved on the outer surface of the guide rod, a slider is slidably connected in the sliding groove, and the slider is slidably connected to the guide rod, one end of the slider is in contact with one end of the spring, a buffer rod is rotatably connected to the top of the slider, and the other end of the buffer rod is rotatably connected to one side of the connecting rod.

[0007] Furthermore, the support mechanism comprises a shielding beam, one side of the shielding beam is integrally formed with a top beam, and one side of the top beam is fixedly connected with a front beam.

[0008] Furthermore, the rotation point of the connecting rod and the buffer rod is located at one-half of the connecting rod.

[0009] Furthermore, the bottom of the shield beam and the top beam are integrally formed with a reinforcing rib plate.

[0010] Furthermore, a push clamp shaft is provided on one side of the base.

[0011] The beneficial effects of the utility model are:

[0012] 1. The utility model uses a spring and a slider to prevent the hydraulic push rod from failing. The buffer rod can buffer the connecting rod, thereby preventing the support mechanism from suddenly losing its supporting force, causing failure of the support function and causing the risk of personal injury.

[0013] 2. The utility model can improve the strength of the support mechanism to a certain extent and improve the use effect of the hydraulic support mechanism by arranging reinforcing ribs at the bottom of the shield beam and the top beam. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Reference Figure 1-Figure 3, an engineering hydraulic support mechanism, including a base 1, an extension seat 2 is integrally formed on one side of the base 1, a hydraulic push rod 3 is rotatably connected to the top of the base 1, two connecting rods 4 are rotatably connected to the top of the base 1, and the top of the connecting rod 4 is rotatably connected to the same supporting mechanism, the other end of the hydraulic push rod 3 is rotatably connected to the supporting mechanism, two slide grooves 8 are arranged on the top of the extension seat 2, and a guide rod 9 is fixed to the inner wall of the slide groove 8 by bolts, a spring 10 is sleeved on the outer surface of the guide rod 9, a slider 11 is slidably connected in the slide groove 8, and the slider 11 is slidably connected to the guide rod 9, one end of the slider 11 contacts with one end of the spring 10, and a buffer rod 12 is rotatably connected to the top of the slider 11. The coordinated use of the spring 10 and the slider 11 can prevent the hydraulic push rod 3 from failing and buffering the connecting rod 4 through the buffer rod 12, thereby preventing the supporting mechanism from suddenly losing its supporting force, resulting in failure of the supporting function, the other end of the buffer rod 12 is rotatably connected to one side of the connecting rod 4, and the rotating point of the connecting rod 4 and the buffer rod 12 is located at one-half of the connecting rod 4.

[0020] Among them, the supporting mechanism includes a shielding beam 5, a top beam 6 is integrally formed on one side of the shielding beam 5, a front beam 7 is fixed to one side of the top beam 6 by bolts, and a reinforcing rib plate 13 is integrally formed at the bottom of the shielding beam 5 and the top beam 6. The reinforcing rib plate 13 can improve the strength of the supporting mechanism to a certain extent and improve the use effect of the hydraulic supporting mechanism. A sliding card shaft 14 is provided on one side of the base 1 for convenient connection with a mobile device.

[0021] The working principle of this embodiment is as follows: during use, when hydraulic support is needed, the hydraulic push rod 3 is started to drive the supporting mechanism to move upward, and the connecting rod 4 will be deflected. When the hydraulic push rod 3 is damaged or fails, the hydraulic push rod 3 will lose power immediately. At this time, the buffer rod 12 on one side of the connecting rod 4 drives the slider 11 to move along the guide rod 9 in the slide groove 8, and contacts the spring 10 mounted on the guide rod 9, so as to buffer the connecting rod 4, thereby preventing the supporting mechanism from instantly losing its supporting force and falling down, thereby causing danger and reducing the risk of accidents.

[0022] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
