Description

Technical Field

[0001] This utility model relates to the field of hydraulic cylinder outrigger technology, specifically to a non-slip and stable hydraulic cylinder outrigger. Background Technology

[0002] Hydraulic cylinder outriggers are components used in engineering and construction equipment to provide stable support and leveling. They are widely used in various engineering and construction equipment requiring stable support and leveling, such as cranes, loader trucks, excavators, and loaders. Hydraulic cylinder outriggers ensure the stability of equipment operating on uneven or unstable ground by providing additional support force, allowing for leveling of the equipment to adapt to different work site requirements. The extension and retraction of the cylinders are achieved through fluid flow and hydraulic control, thereby adjusting the length and position of the outriggers.

[0003] Hydraulic cylinder outriggers typically consist of a cylinder body, piston rod, guide sleeve, connecting parts, and piston. When fluid is pushed into the cylinder, the piston is pushed by hydraulic pressure, thereby achieving the extension and retraction of the cylinder. The cylinder is connected to the hydraulic system through hydraulic lines, and the hydraulic cylinder is driven by the flow of fluid in the lines. Some hydraulic cylinder outriggers can be integrated into the automated control system of the entire equipment to achieve more efficient and automated leveling operations.

[0004] The support plate at the bottom of the hydraulic cylinder outrigger is usually supported by a large metal plate with anti-slip texture. It has a decent anti-slip effect on hard surfaces, but under complex working conditions such as soft ground, the traditional hydraulic cylinder outrigger often has poor anti-slip performance. Soft ground can easily cause the outrigger to sink. In view of this, this application proposes an anti-slip and stable hydraulic cylinder outrigger. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a non-slip and stable hydraulic cylinder outrigger that can be stably installed on both hard and soft surfaces. It solves the problem that the support plate at the bottom of the hydraulic cylinder outrigger, which is usually supported by a large metal plate with anti-slip texture, has a decent anti-slip effect on hard surfaces, but often suffers from poor anti-slip performance in complex working conditions such as soft ground, and the outrigger is prone to sinking on soft ground.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a non-slip and stable hydraulic cylinder support leg, comprising a hydraulic cylinder, an external threaded rod fixedly installed at the bottom of the hydraulic cylinder, a supporting base plate fixedly installed at the bottom of the external threaded rod, a sliding sleeve plate slidably installed on the surface of the external threaded rod, an anti-slip insert fixedly installed at the bottom of the sliding sleeve plate, the anti-slip insert slidingly penetrating the supporting base plate, an insertion tip fixedly installed at the bottom end of the anti-slip insert, and a clamping nut threadedly installed on the surface of the external threaded rod.

[0007] Furthermore, the top of the sliding sleeve is provided with a mounting through hole, which is adapted to the external threaded rod.

[0008] Furthermore, the clamping nut is located above the sliding sleeve, and a piston rod is slidably mounted on the bottom of the hydraulic cylinder.

[0009] Furthermore, a top plate is fixedly installed at the bottom of the piston rod, and an external threaded rod is fixedly installed at the bottom of the top plate.

[0010] Furthermore, a base is fixedly installed on the top of the hydraulic cylinder, and a limit hole is opened on the top of the support base plate, with the anti-slip rod matching the limit hole.

[0011] Furthermore, an inner mounting groove is fixedly installed at the bottom of the supporting base plate, and an inner anti-slip ring is embedded inside the inner mounting groove.

[0012] Furthermore, an outer mounting groove is fixedly installed at the bottom of the support base plate, and an outer anti-slip ring is embedded inside the outer mounting groove. The anti-slip rod is located between the inner mounting groove and the outer mounting groove.

[0013] Compared with the prior art, this utility model provides a non-slip and stable hydraulic cylinder outrigger, which has the following beneficial effects:

[0014] This anti-slip and stable hydraulic cylinder outrigger features an external threaded rod at the bottom of the hydraulic cylinder, with a support base plate at the bottom of the threaded rod. On hard surfaces, the support base plate provides support. On soft surfaces, tightening the nut causes the sliding sleeve to press down, inserting the anti-slip rod into the soft ground for added stability. This design solves the problem of traditional hydraulic cylinder outriggers, which typically use large metal plates with anti-slip grooves at the bottom. While these plates offer adequate anti-slip on hard surfaces, they often fail to provide sufficient stability on soft surfaces or other complex conditions, leading to instability and potential sinking.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 4 A non-slip and stable hydraulic cylinder outrigger includes a hydraulic cylinder 1, an externally threaded rod 2 fixedly mounted at the bottom of the hydraulic cylinder 1, a supporting base plate 3 fixedly mounted at the bottom of the externally threaded rod 2, a sliding sleeve plate 4 slidably mounted on the surface of the externally threaded rod 2, an anti-slip insert rod 5 fixedly mounted at the bottom of the sliding sleeve plate 4, the anti-slip insert rod 5 slidingly penetrating the supporting base plate 3, and an insertion tip 6 fixedly mounted at the bottom end of the anti-slip insert rod 5. A clamping nut 7 is threadedly mounted on the surface of the externally threaded rod 2. Rotating the clamping nut 7 causes it to descend, pressing the sliding sleeve plate 4 downwards, which in turn presses the anti-slip insert rod 5 downwards, allowing it to insert into the soft ground through the insertion tip 6, thus making the hydraulic cylinder 1 more firmly attached to the ground.

[0022] The sliding sleeve 4 has a mounting through hole 41 at its top, which is adapted to the external threaded rod 2. The sliding sleeve 4 moves up and down on the surface of the external threaded rod 2.

[0023] Secondly, the clamping nut 7 is located above the sliding sleeve 4, and the piston rod 8 is slidably mounted on the bottom of the hydraulic cylinder 1. When the clamping nut 7 rotates, it moves up and down on the surface of the external thread rod 2, thereby limiting the movement of the sliding sleeve 4.

[0024] Meanwhile, a top plate 9 is fixedly installed at the bottom of the piston rod 8, and an external threaded rod 2 is fixedly installed at the bottom of the top plate 9. When the hydraulic cylinder 1 is activated, it drives the piston rod 8 to extend out of the hydraulic cylinder 1, which in turn drives the top plate 9 to move downward, causing the supporting base plate 3 to press against the ground.

[0025] It should be noted that hydraulic cylinder 1 is a common cylinder component of hydraulic outriggers, consisting of a cylinder body, piston rod 8, guide sleeve, connecting parts, and piston. When fluid is pushed into the cylinder, the piston is pushed by hydraulic pressure, thereby realizing the extension and retraction of the cylinder.

[0026] The hydraulic cylinder 1 has a base 10 fixedly mounted on its top. The support base plate 3 has a limit hole 11 on its top, and the anti-slip rod 5 is adapted to the limit hole 11. The base 10 is installed at the bottom of the equipment, and the anti-slip rod 5 extends through the limit hole 11 to the bottom of the support base plate 3.

[0027] Meanwhile, an inner mounting groove 12 is fixedly installed at the bottom of the supporting base plate 3, and an inner anti-slip ring 13 is embedded inside the inner mounting groove 12. The inner anti-slip ring 13 is installed in the inner mounting groove 12, and the inner anti-slip ring 13 contacts the hard ground to achieve an anti-slip effect. When the inner anti-slip ring 13 is damaged, it can be replaced.

[0028] The bottom of the supporting base plate 3 is fixedly installed with an outer mounting groove 14, and an outer anti-slip ring 15 is embedded inside the outer mounting groove 14. The anti-slip rod 5 is located between the inner mounting groove 12 and the outer mounting groove 14. The outer anti-slip ring 15 is installed in the outer mounting groove 14, and the outer anti-slip ring 15 contacts the hard ground to achieve an anti-slip effect. When the outer anti-slip ring 15 is damaged, it can be replaced.

[0029] In this embodiment, when the hydraulic cylinder 1 is activated, it drives the piston rod 8 to descend, which in turn drives the top plate 9 to descend and the external threaded rod 2 to descend, causing the supporting base plate 3 to press against the ground. The inner anti-slip ring 13 and the outer anti-slip ring 15 contact the hard ground to achieve an anti-slip effect. When encountering soft ground, the clamping nut 7 is rotated, causing it to descend and press the sliding sleeve 4 downward, which in turn drives the anti-slip rod 5 to descend, pass through the supporting base plate 3, and insert into the soft ground through the insertion tip 6, making the hydraulic cylinder 1 more firmly attached to the ground.
