Description

Technical Field

[0001] The utility model belongs to the technical field of hydraulic supports, and in particular relates to a hydraulic support with high bearing capacity. Background Art

[0002] The hydraulic support is a structure used to control the mine pressure at the coal mining face. The mine pressure at the mining face acts on the hydraulic support in the form of external load. In the mechanical system of the interaction between the hydraulic support and the surrounding rock of the mining face, if the combined force of the supporting parts of the hydraulic support and the combined force of the external load acting on the hydraulic support by the roof are exactly in the same line, then the hydraulic support is very adaptable to the surrounding rock of this mining face.

[0003] The bearing capacity of the existing hydraulic supports has certain limitations. A hydraulic support with low bearing capacity means that it can only bear lighter loads. When bearing heavier loads, it may cause serious consequences such as equipment overturning and structural damage. Therefore, it cannot meet the requirements in situations where a larger load is required, which limits its scope of use and application areas. Utility Model Content

[0004] The technical problem to be solved by the utility model is that a hydraulic support with low bearing capacity may cause structural damage, thus limiting its use range and application field.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a hydraulic support with high load-bearing capacity, including a base and a supporting mechanism, the bottom of the base is fixedly installed with the supporting mechanism, the supporting mechanism includes a supporting bottom plate, a supporting side plate and positioning holes, the supporting bottom plate is fixedly installed at the bottom of the base, the supporting side plates are respectively fixedly installed on the front and back sides of the supporting bottom plate, and the positioning holes are opened on the surfaces of the supporting side plates.

[0006] As a preferred embodiment of the present invention, the supporting bottom plate and the supporting side plates are connected by connecting rods.

[0007] As a preferred embodiment of the present invention, the support mechanism is connected to the support surface via a fixing rod.

[0008] As a preferred embodiment of the utility model, a column lever is fixedly mounted on the top of the base, and a column piston is movably mounted on the top of the column lever.

[0009] As a preferred embodiment of the utility model, a top beam is fixedly installed on the top of the column piston, top side plates are fixedly installed on the front and back sides of the top beam, a front beam is fixedly installed on the left side of the top beam, and the top beam and the front beam are connected by a connecting pin.

[0010] As a preferred embodiment of the present invention, a shielding beam is fixedly installed on the right side of the top beam, and side guard plates are fixedly installed on the front and back sides of the shielding beam.

[0011] As a preferred embodiment of the utility model, a front connecting rod is fixedly installed on the left side of the bottom of the shield beam, a rear connecting rod is fixedly installed on the right side of the front connecting rod, and rear guard plates are fixedly installed on the front and back sides of the rear connecting rod.

[0012] The beneficial effects of the utility model are:

[0013] 1. This kind of hydraulic support with high load-bearing capacity, through the setting of the support mechanism, can unfold the support side panels when the hydraulic support carries a large load, and form a larger support plane together with the support bottom plate, and then use the fixing rod to connect and fix the support surface, so as to achieve the purpose of increasing the support area, disperse the load to a larger area, reduce local stress concentration, thereby improving the load-bearing capacity, and enable the support to stably withstand greater pressure and weight, providing more reliable support and protection. When the load carried by the hydraulic support is small or during transportation, the support side panels can be folded up, so that the hydraulic support occupies less space during transportation and storage. This is very beneficial for mobile or temporary hydraulic supports, and can be easily carried, loaded and unloaded, and stored, thereby improving the flexibility and efficiency of use.

[0014] 2. This hydraulic support with high load-bearing capacity can flexibly unfold and fold the supporting side panels through the setting of connecting rods, thereby realizing flexible adjustment of the supporting mechanism, which is very important for adapting to different working scenes and can meet the needs of different projects. Through the setting of side guard plates, the rigidity and stability of the entire support structure can be increased, the role of strengthening the beam can be played, and the deformation and deflection of the beam during the load-bearing process can be reduced, thereby improving the overall load-bearing capacity of the hydraulic support.

DETAILED DESCRIPTION

[0021] The present invention will now be further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0022] like Figures 1 to 5 As shown, the utility model provides a hydraulic support with high bearing capacity, including a base 1 and a support mechanism 2. The support mechanism 2 is fixedly installed on the bottom of the base 1. The support mechanism 2 includes a support bottom plate 201, a support side plate 202 and a positioning hole 203. The support bottom plate 201 is fixedly installed on the bottom of the base 1, and the support side plates 202 are respectively fixedly installed on the front and back of the support bottom plate 201. The positioning holes 203 are opened on the surface of the support side plates 202.

[0023] refer to Figure 1 , Figure 2 and Figure 3 The supporting bottom plate 201 and the supporting side plate 202 are connected by a connecting rod 204, the supporting mechanism 2 is connected to the supporting surface by a fixing rod 205, a column lever 3 is fixedly installed on the top of the base 1, and a column piston 4 is movably installed on the top of the column lever 3.

[0024] By adopting the above solution: through the setting of the connecting rod 204, the supporting side panels 202 can be flexibly unfolded and folded, thereby realizing flexible adjustment of the supporting mechanism 2, which is very important for adapting to different working scenes and can meet the needs of different projects.

[0025] refer to Figure 3 , Figure 4 and Figure 5 A top beam 5 is fixedly installed on the top of the column piston 4, and top side plates 6 are fixedly installed on the front and back of the top beam 5, a front beam 7 is fixedly installed on the left side of the top beam 5, and the top beam 5 and the front beam 7 are connected by a connecting pin 8, a shielding beam 9 is fixedly installed on the right side of the top beam 5, and side guard plates 10 are fixedly installed on the front and back of the shielding beam 9, a front connecting rod 11 is fixedly installed on the left side of the bottom of the shielding beam 9, a rear connecting rod 12 is fixedly installed on the right side of the front connecting rod 11, and a rear guard plate 13 is fixedly installed on the front and back of the rear connecting rod 12.

[0026] By adopting the above scheme, the side guard plate 10 is provided to increase the rigidity and stability of the entire support structure, play the role of strengthening the beam, reduce the deformation and deflection of the beam during the load-bearing process, and thus improve the overall load-bearing capacity of the hydraulic support.

[0027] Working principle:

[0028] When in use, place the support in the use position according to the installation instructions and design requirements of the hydraulic support to ensure that the support is stable, and adjust it according to the support base plate 201 to ensure that the support is in stable contact with the working surface. When the support load is large, unfold the support side plates 202 on both sides of the base 1, and use the fixing rod 205 to connect and fix the support side plates 202 to the contact surface through the positioning holes 203, so that the support side plates 202 and the support base plate 201 together form a larger support surface, ensuring that the load does not exceed the load-bearing capacity of the hydraulic support.

[0029] To sum up: this hydraulic support with high load-bearing capacity, through the coordinated use of the supporting bottom plate 201 and the supporting side plate 202, solves the problem that the load-bearing capacity of the existing hydraulic support has a certain limit. The low load-bearing capacity hydraulic support means that it can only bear a lighter load. When carrying a heavier load, it may cause serious consequences such as equipment overturning and structural damage. Therefore, it cannot meet the requirements in occasions where a larger load is required, which limits its scope of use and application areas.
