Technical Field

[0001] The utility model relates to the technical field of hydraulic supports, in particular to a novel top beam structure of a hydraulic support. Background Art

[0002] The hydraulic support top beam structure is the bridge between the hydraulic support of the fully mechanized mining working face of the coal mine and the coal seam. Generally, the hydraulic support top beam structure is a plate welding structure. Although it can meet the strength, rigidity and functional requirements, most hydraulic support top beam structures are heavy, have a large amount of materials, and are difficult to maintain due to space limitations.

[0003] In order to solve the above problems, people have been seeking an ideal technical solution. Summary of the Invention

[0004] The purpose of the present invention is to address the deficiencies of the prior art and thereby provide a novel hydraulic support top beam structure. The present invention uses a closed loop composed of longitudinal beams and transverse beams to allow energy to circulate within the closed loop when bearing loads. At the same time, the longitudinal beams and transverse beams are designed as H-shaped beams, which can fully utilize the force-bearing characteristics of the H-shaped beams, so that the top beam structure can minimize weight, reduce the amount of materials, and increase maintenance space while ensuring strength, rigidity, and functionality.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a new type of hydraulic support top beam structure, including a top plate and four longitudinal beams spaced left and right, the longitudinal beams are main ribs arranged longitudinally, and a number of first cross beams are arranged at intervals between two adjacent longitudinal beams. The longitudinal beams and the first cross beams are both H-shaped beams. The overall structure composed of each longitudinal beam and each first cross beam is a closed ring, and the top plate is arranged on top of the closed ring.

[0006] Based on the above, the first cross beams on the left, middle and right sides are arranged in rows in a one-to-one correspondence.

[0007] Based on the above, it also includes two column sockets, which are symmetrically arranged on the left and right. The column socket on the left is fixed to the bottom surface of the top plate between the two longitudinal beams on the left, and the column socket on the right is fixed to the bottom surface of the top plate between the two longitudinal beams on the right;

[0008] Two avoidance beams are symmetrically arranged between the two longitudinal beams on the left side and on the front and rear sides of the column socket on the left side, and between the two longitudinal beams on the right side and on the front and rear sides of the column socket on the right side;

[0009] Two second cross beams are arranged at intervals in front and back between the two middle longitudinal beams at corresponding positions between the two column sockets. The two second cross beams and the two middle longitudinal beams form a closed loop.

[0010] Based on the above, the avoidance beam is a curved beam with the opening facing downward.

[0011] Based on the above, the second crossbeam is an H-shaped beam.

[0012] Based on the above, the two avoidance beams correspond to the two second cross beams on the left and right respectively.

[0013] The present invention has substantial features and progress compared to the prior art. Specifically, the present invention is provided with four longitudinal beams, and a plurality of first cross beams are arranged at intervals between two adjacent longitudinal beams. The overall structure composed of each longitudinal beam and each first cross beam is a closed ring. The top plate is arranged above the closed ring, and energy circulates in the closed ring when bearing load. At the same time, the longitudinal beams and the first cross beams are both H-shaped beams. The design fully utilizes the force characteristics of the H-shaped beam, so that the top beam structure can minimize weight, reduce the amount of materials, and increase maintenance space while ensuring strength, rigidity and function.

[0014] Furthermore, two column sockets are provided, and avoidance beams are symmetrically provided on the front and rear sides of the column sockets. The avoidance beams can not only increase the structural strength but also ensure the normal function of the column sockets. At the same time, two second cross beams are provided between the two middle longitudinal beams and between the two column sockets. The second cross beams also adopt H-shaped beams. The two second cross beams and the two middle longitudinal beams also form a closed loop, so that the strength and stiffness of the top beam structure at the column sockets meet the working requirements.

[0018] The technical solution of the present utility model is further described in detail below through specific implementation methods.

[0019] like Figure 1 and Figure 2 As shown, a novel hydraulic support top beam structure comprises a top plate 1 and four longitudinal beams 2 spaced apart. The longitudinal beams 2 are longitudinally arranged main ribs. Five first cross beams 3 are spaced front and back between adjacent longitudinal beams 2. Both the longitudinal beams 2 and the first cross beams 3 are H-shaped beams. The overall structure formed by each longitudinal beam 2 and each first cross beam 3 forms a closed loop, with the top plate 1 positioned above the closed loop. This design allows energy to circulate within the closed loop when subjected to load. Furthermore, due to the advantages of H-shaped beams, such as strong bending resistance, simple construction, cost savings, and lightweight structure, this top beam structure minimizes weight, reduces material requirements, and increases maintenance space while ensuring strength, rigidity, and functionality.

[0020] In this embodiment, the five first cross beams 3 on the left, the five first cross beams 3 in the middle and the five first cross beams 3 on the right are arranged in a row in a one-to-one correspondence. This design structure has better stress resistance.

[0021] This embodiment further includes two column sockets 4, which are symmetrically arranged on the left and right. The column socket 4 on the left is fixed to the bottom surface of the top plate 1 between the two longitudinal beams 2 on the left, and the column socket 4 on the right is fixed to the bottom surface of the top plate 1 between the two longitudinal beams 2 on the right.

[0022] Two avoidance beams 5 are symmetrically arranged between the two longitudinal beams 2 on the left side and on the front and rear sides of the left column socket 4, and between the two longitudinal beams 2 on the right side and on the front and rear sides of the right column socket 4;

[0023] Two second cross beams 6 are arranged at intervals in front and back between the two middle longitudinal beams 2 at corresponding positions between the two column sockets 4. The two second cross beams 6 and the two middle longitudinal beams 2 form a closed loop.

[0024] Specifically, the avoidance beam 5 is a curved beam with its opening facing downward.

[0025] Specifically, the second cross beam 6 is an H-shaped beam.

[0026] Specifically, the two avoidance beams 5 correspond to the two second cross beams 6 on the left and right sides respectively.

[0027] The provision of the avoidance beam 5 in the top beam structure not only increases the structural strength but also ensures the normal function of the column socket 4. By providing the second cross beam 6, which is also designed as an H-beam, the two second cross beams 6 and the two longitudinal beams 2 in the middle also form a closed loop, so that the strength and rigidity of the top beam structure at the column socket 4 meet the working requirements.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and not to limit it; although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents; without departing from the spirit of the technical solution of the utility model, they should all be included in the scope of the technical solution for which protection is requested in the utility model.
