Description

Technical Field

[0001] This utility model relates to the field of adjustable beam technology, and in particular to a spring-type adjustable beam structure. Background Technology

[0002] In the field of modern engineering construction, the adjustable beam structure, as a key component for supporting and adjusting loads, is widely used in many industries such as construction, transportation, and machinery. Its performance directly affects the stability and safety of the overall project.

[0003] Currently, one type of spring-loaded adjustable beam structure lacks elastic buffer components. In steeply inclined fully mechanized mining faces, it is difficult to effectively fix the support through pre-tightening force, which easily leads to support slippage and insufficient stability. The connection between the adjustable beam and the support is mostly a rigid structure without the synergistic effect of springs. It is impossible to compensate for structural displacement through pre-tightening force, which easily causes fatigue damage under dynamic loads and shortens the service life. Utility Model Content

[0004] The purpose of this invention is to address the problems in the existing technology where there is a lack of elastic buffer components, making it difficult to effectively fix the support through pre-tightening force in steeply inclined fully mechanized mining faces, leading to support slippage, insufficient stability, and the connection between the adjusting beam and the support being mostly a rigid structure without spring coordination, making it impossible to compensate for structural displacement through pre-tightening force, which easily causes fatigue damage under dynamic loads and shortens service life. Therefore, a spring-type adjusting beam structure is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a spring-type adjustable beam structure, comprising an adjustable beam body, wherein a right adjustable beam and a left adjustable beam are provided within the adjustable beam body, a support base is provided between the right and left adjustable beams, a telescopic jack is installed inside both the right and left adjustable beams, and a guide shaft is installed on one side of each telescopic jack inside both the right and left adjustable beams, one end of the guide shaft and the output end of the telescopic jack are both connected to the support base, and a spring body is sleeved on the outer side of the guide shaft.

[0006] Preferably, both ends of the telescopic jack and the guide shaft are installed via fixed shafts.

[0007] Preferably, a first connecting plate is installed inside the bracket base, and a connecting shaft matching the output end of the telescopic jack is installed inside the first connecting plate.

[0008] Preferably, a second connecting plate is installed inside the bracket base, and a plug cylinder matching the guide shaft is installed inside the second connecting plate.

[0009] Preferably, two telescopic jacks are installed in the right and left adjusting beams respectively, and the spring is located between the two telescopic jacks.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] In this invention, the spring body is fitted onto the guide shaft, ensuring that the spring body remains compressed and maintains preload after the main beam extends, firmly supporting the support base and effectively preventing it from sliding down the working surface at large inclination angles. The guide shaft provides linear guidance for the extension and retraction of the spring body, preventing it from shifting or twisting and ensuring the stability and reliability of the structural extension and retraction. The symmetrical design allows for direct reversal of installation when changing the working surface direction, eliminating the need for additional adjustments or replacements, thus simplifying the operation. The elastic properties of the spring body can buffer dynamic load impacts, reducing rigid collisions between the main beam and the support base, lowering the risk of structural fatigue damage, and extending service life.

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Example 1, as Figure 1-5 As shown, this utility model provides a spring-type adjustable beam structure, including an adjustable beam body 1. The adjustable beam body 1 has a right adjustable beam 11 and a left adjustable beam 12. A support base 6 is provided between the right adjustable beam 11 and the left adjustable beam 12. Telescopic jacks 2 are installed in both the right adjustable beam 11 and the left adjustable beam 12. A guide shaft 3 is installed on one side of the telescopic jack 2 in both the right adjustable beam 11 and the left adjustable beam 12. One end of the guide shaft 3 and the output end of the telescopic jack 2 are connected to the support base 6. A spring body 4 is sleeved on the outside of the guide shaft 3.

[0021] The overall effect of Embodiment 1 is as follows: First, the cylinder bottom end of the telescopic jack 2 is installed inside the main body 1 of the adjusting beam and fixed with a fixing shaft 5, etc. Then, one end of the guide shaft 3 is installed inside the main body 1 of the adjusting beam, and the spring body 4 is fitted onto the guide shaft 3. Finally, the assembled left adjusting beam 12 and right adjusting beam 11 with the spring body 4 are installed on both sides of the support base 6, and the two telescopic jacks 2, the guide shaft 3, and the spring body 4 are installed on both sides of the base of the support base 6. Then, the piston rod ends of the two telescopic jacks 2 are fixed to the support base 6 with the fixing shaft 5.

[0022] Example 2, as Figure 1-5 As shown, both ends of the telescopic jack 2 and the guide shaft 3 are installed via a fixed shaft 5. A first connecting plate 9 is installed inside the bracket base 6, and a connecting shaft 7 matching the output end of the telescopic jack 2 is installed inside the first connecting plate 9. A second connecting plate 10 is installed inside the bracket base 6, and a plug 8 matching the guide shaft 3 is installed inside the second connecting plate 10. Two telescopic jacks 2 are installed in the right adjusting beam 11 and the left adjusting beam 12 respectively, and the spring body 4 is located between the two telescopic jacks 2.

[0023] The overall effect of Embodiment 2 is that, through the design of the spring body 4 being sleeved on the guide shaft 3, the spring body 4 remains in a compressed state and maintains pre-tension after the main body 1 of the adjusting beam extends, firmly supporting the support base 6 and effectively preventing the support base 6 from sliding down the working surface at a large inclination angle. The guide shaft 3 provides linear guidance for the extension and retraction of the spring body 4, avoiding the spring body 4 from deflection or twisting, ensuring the stability and reliability of the structural extension and retraction. The structure adopts a symmetrical design, and can be directly reversed when changing the working surface direction without additional adjustment or replacement of parts, simplifying the operation process. The elastic characteristics of the spring body 4 can buffer the impact of dynamic loads, reduce the rigid collision between the main body 1 of the adjusting beam and the support base 6, reduce the risk of structural fatigue damage, and extend the service life.

[0024] Working Principle: In operation, the telescopic jack 2 is a hydraulically driven jack, with its extension and retraction controlled by an external hydraulic system. The piston rod of the hydraulically driven telescopic jack 2 extends and retracts, causing the main body 1 of the adjusting beam to extend. The extended main body 1 interacts with the base support to form a support point. Simultaneously, the spring body 4 and guide shaft 3 extend in tandem. The guide shaft 3 guides the extension and retraction of the spring body 4, ensuring it extends and retracts in a straight line, preventing deviation or twisting. After the main body 1 extends, the spring body 4 remains compressed, possessing a certain preload. This preload acts on the base support 6 through the main body 1, firmly supporting the base support 6 and effectively preventing it from slipping. This ensures the base support 6 remains stable in steep-angle fully mechanized mining faces, providing reliable safety assurance for steep-angle fully mechanized mining.

[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
