Description

Technical Field

[0001] This utility model relates to the field of hydraulic outrigger cylinder technology, specifically to an anti-tipping self-stabilizing hydraulic outrigger cylinder. Background Technology

[0002] Hydraulic outrigger cylinders are hydraulic components widely used in engineering machinery, construction machinery, and mining machinery. Their main function is to provide stable support for equipment. A hydraulic outrigger cylinder mainly consists of a cylinder body, piston rod, piston, and seals. During use, a hydraulic pump in the hydraulic system delivers hydraulic oil to the inlet of the outrigger cylinder. After the hydraulic oil enters the cylinder body, it acts on the piston, generating pressure to push the piston rod outward, causing the outrigger to extend and support the ground, thus achieving the supporting effect.

[0003] A search revealed Chinese patent application CN202222606393.3, which discloses an anti-tipping self-stabilizing hydraulic outrigger cylinder. This cylinder relates to the field of hydraulic outrigger cylinder technology. The anti-tipping self-stabilizing hydraulic outrigger cylinder includes a hydraulic cylinder with a hydraulic outrigger inside. A support plate is fixedly mounted at the bottom of the hydraulic outrigger, and an inclined support rod is mounted on the top of the support plate. A positioning mechanism for fixing the support rod is provided between the support rod and the support plate. A mounting plate is provided on the side wall of the hydraulic cylinder along its height direction. In this prior art, the hydraulic outrigger lowers the support plate by adjusting the hydraulic cylinder, causing it to contact the ground and thus providing support.

[0004] In the aforementioned prior art, although the adjustment of the hydraulic cylinder can be used to move the outrigger downwards, thereby using the contact between the support plate and the ground to provide auxiliary support for the hydraulic outrigger cylinder, the diameter of the support plate in the hydraulic outrigger cylinder of the aforementioned prior art is fixed, resulting in a fixed contact area with the ground. However, after the hydraulic outrigger cylinder is extended, its length increases. Therefore, when the support plate supports and restricts the hydraulic outrigger cylinder, it is easy for it to tilt, which in turn makes the hydraulic outrigger cylinder prone to tipping over. Utility Model Content

[0005] The purpose of this utility model is to provide a self-stabilizing hydraulic outrigger cylinder that prevents tipping, thereby solving the problem that in the prior art, the area of ​​the support plate at the lower end of the hydraulic outrigger cylinder in contact with the ground remains unchanged during use, and tipping is likely to occur as the hydraulic outrigger cylinder extends.

[0006] This utility model provides the following technical solution: a self-stabilizing hydraulic outrigger cylinder for preventing tipping, comprising a cylinder body, a top plate fixedly connected to the upper end of the cylinder body, and a support plate fixedly connected to the lower end of the cylinder body, and support components fixedly connected to both ends of the cylinder body, wherein the support components include a threaded cylinder fixedly connected to the outer side of the upper end of the cylinder body, a threaded sleeve sleeved on the outer side of the threaded cylinder, and a positioning sleeve rotatably connected to the lower end of the threaded sleeve.

[0007] Through the above technical solution, by utilizing the threaded engagement between the threaded cylinder and the threaded sleeve, the threaded sleeve can rotate and push the positioning sleeve and other components to move.

[0008] As a preferred embodiment of the above technical solution, the lower end of the positioning sleeve is rotatably connected to a first bracket, and the end of the first bracket away from the positioning sleeve is rotatably connected to a second bracket, and the end of the second bracket away from the first bracket is rotatably connected to the cylinder body.

[0009] The above technical solution, through the rotatable connection between the first bracket and the second bracket, facilitates the positioning sleeve to push the first bracket to move.

[0010] As a preferred embodiment of the above technical solution, a spring is provided at the middle of the first bracket and the second bracket, and an adapter is fixedly connected to both ends of the spring. The upper adapter is rotatably connected to the first bracket, and the lower adapter is rotatably connected to the second bracket.

[0011] The above technical solution utilizes the elastic potential energy of the spring to facilitate the rotation of the second support by the first support.

[0012] As a preferred embodiment of the above technical solution, a connecting plate is fixedly connected to the outer side of the second bracket near the first bracket, and a first support plate is fixedly connected to the end of the connecting plate away from the second bracket.

[0013] The above technical solution allows the first support plate to support the second bracket, etc.

[0014] As a preferred embodiment of the above technical solution, an insert plate is inserted into one end of the first support plate, and a second support plate is fixedly connected to the end of the insert plate away from the first support plate.

[0015] The above technical solution allows the second support plate to be attached to the first support plate using a plug plate, which facilitates the first support plate in supporting the second bracket, etc.

[0016] As a preferred embodiment of the above technical solution, a rubber disc is fixedly connected to the lower end of the support disc, and a frosted disc is fixedly connected to the lower end of the rubber disc.

[0017] The above technical solution utilizes rubber discs and frosted discs to improve the stability of the support disc during placement.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This anti-tipping self-stabilizing hydraulic outrigger cylinder can increase the contact area between the hydraulic outrigger cylinder and the ground through the support components, thereby improving support stability and preventing tipping due to the extension of the hydraulic outrigger cylinder.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] like Figure 1 - Figure 5 As shown, this utility model provides a technical solution: an anti-tipping self-stabilizing hydraulic outrigger cylinder, including a cylinder body 1, a top plate 11 fixedly connected to the upper end of the cylinder body 1, and a support plate 12 fixedly connected to the lower end of the cylinder body 1. Support components 2 are fixedly connected to both ends of the cylinder body 1, and the support components 2 include a threaded cylinder 21 fixedly connected to the outer side of the upper end of the cylinder body 1, a threaded sleeve 22 engaged on the outer side of the threaded cylinder 21, and a positioning sleeve 23 rotatably connected to the lower end of the threaded sleeve 22. When using the hydraulic outrigger cylinder, the contact area between the hydraulic outrigger cylinder and the ground can be increased by the support components 2, thereby improving the support stability and preventing the outrigger cylinder from tipping over due to its extension.

[0028] like Figure 1 , Figure 2 and Figure 4 As shown, the lower end of the positioning sleeve 23 is rotatably connected to the first bracket 24, and the end of the first bracket 24 away from the positioning sleeve 23 is rotatably connected to the second bracket 25. The end of the second bracket 25 away from the first bracket 24 is rotatably connected to the cylinder 1. By pushing the first bracket 24 to rotate through the positioning sleeve 23, the first bracket 24 can synchronously drive the second bracket 25 to rotate and adjust.

[0029] like Figure 1 and Figure 4 As shown, a spring 26 is provided at the middle of the first bracket 24 and the second bracket 25, and an adapter 27 is fixedly connected to both ends of the spring 26. The upper adapter 27 is rotatably connected to the first bracket 24, and the lower adapter 27 is rotatably connected to the second bracket 25. The spring 26 rotates with the assistance of the adapter 27, and the elastic potential energy of the spring 26 itself is used to help the first bracket 24 push the second bracket 25 to rotate.

[0030] like Figure 4 As shown, a connecting plate 28 is fixedly connected to the outer side of the second bracket 25 near the first bracket 24, and a first support plate 29 is fixedly connected to the end of the connecting plate 28 away from the second bracket 25. The connecting plate 28 and the first support plate 29 facilitate the use of the first bracket 24 and the second bracket 25 to support the cylinder 1.

[0031] like Figure 3 As shown, a plug plate 210 is inserted into one end of the first support plate 29, and a second support plate 211 is fixedly connected to the end of the plug plate 210 away from the first support plate 29. The plug plate 210 is inserted into the first support plate 29 by the second support plate 211, so that the second support plate 211 of different shapes can play an auxiliary restraint and auxiliary support role for the first support plate 29.

[0032] like Figure 5 As shown, a rubber disc 212 is fixedly connected to the lower end of the support disc 12, and a frosted disc 213 is fixedly connected to the lower end of the rubber disc 212. The rubber disc 212 and the frosted disc 213 are used to improve the stability of the support disc 12 when it is placed.

[0033] Working principle: When using the hydraulic outrigger cylinder, first turn the threaded sleeve 22 to move it through thread engagement with the threaded sleeve 21. After the threaded sleeve 22 rotates and moves, it pushes the positioning sleeve 23 to move and compress the first support 24. After being compressed, the first support 24, through the elastic potential energy of the spring 26, compresses the second support 25. After being compressed, the second support 25 drives the connecting plate 28 and the first support plate 29 to rotate. When the second support 25 rotates to be parallel with the support plate 12, the second support 25 is locked by the support plate 12, while the first support plate 29 is parallel to the ground. Subsequently, different second support plates 211 can be brought along according to the usage requirements. The movable insert plate 210 is inserted into the first support plate 29. Then, the first support plate 29, the second support plate 211, the first bracket 24, and the second bracket 25 support the cylinder body 1, thereby improving the support effect of the support plate 12 on the cylinder body 1. At the same time, the rubber plate 212 and the frosted plate 213 can enhance the friction and buffering force on the bottom of the support plate 12, further improving stability. After use, the threaded sleeve 22 can be turned in the opposite direction to move the positioning sleeve 23 upward. Then, with the help of the elastic potential energy of the spring 26, the first bracket 24 and the second bracket 25 can drive the connecting plate 28 and the first support plate 29 back to their original positions.

[0034] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
