Description

Technical Field

[0001] The utility model relates to the technical field of tunnel support, in particular to a support device. Background Art

[0002] Coal, my country's primary energy source, continues to see growing demand. Technological advancements are driving increasing automation and intelligent capabilities in coal mining operations. However, due to the complexity of the process flow, tunneling operations have a relatively low level of automation, leading to an increasingly prominent "mining-excavation imbalance" in coal mining. In my country, underground mining is the primary method of coal mining. To ensure the safety of underground operations, newly excavated tunnels require timely support to enhance the stability of the surrounding rock, thereby improving operational safety.

[0003] Currently, tunnel support work consumes over 60% of tunnel forming time and requires over 70% of the labor force. This work relies primarily on manual operation of a single piece of equipment. This approach presents safety risks, places high demands on workers, and results in low productivity. In short, tunnel support work is not only time-consuming and labor-intensive, but also inefficient. The compressive strength of the support equipment remains unknown after completion, making it crucial to ensure safe support operations. Technological innovation is urgently needed to improve this situation. Utility Model Content

[0005] To achieve the above purpose, the present invention provides the following solutions:

[0006] The utility model provides a support device, comprising a plurality of support connecting plates and four hydraulic support mechanisms; each adjacent two support connecting plates can be rotatably connected to each other; each support connecting plate forms an arc-shaped plate after being connected, and the outer top of the arc-shaped plate is used to support the support surface; the hydraulic support mechanism has a lifting end that can be lifted and lowered in a vertical direction; the two ends of the support connecting plate located at the end are respectively rotatably connected to the lifting end of one of the hydraulic support mechanisms; a movable gap is provided between two adjacent support connecting plates, and the movable gap can make each support connecting plate approach or move away from the adjacent support connecting plate; a pressure sensor is provided in the movable gap.

[0007] Preferably, a mounting groove is provided on the arc-shaped plate, and an arc-shaped support beam is provided in the mounting groove.

[0008] Preferably, a wire threading groove is provided on the arc-shaped support beam, and the wire harness of each pressure sensor is passed through the wire threading groove.

[0009] Preferably, the opening of the threading groove can be closed by an inner side wall of the installation groove.

[0014] Compared with the prior art, the utility model has achieved the following technical effects:

[0015] The support device provided by the utility model adopts a plurality of support connecting plates to form an arc-shaped plate for supporting the support surface. As the top pressure increases, the support connecting plates can be more tightly connected to each other, thereby improving the support pressure bearing capacity and ensuring the support effect. During support, the support operation can be completed by four hydraulic support mechanisms, reducing manual operation and reducing labor intensity. The pressure sensor arranged in the movable gap between each two adjacent support connecting plates can monitor the top pressure condition.

[0016] Furthermore, the arc-shaped support beam is arranged in the installation groove of the arc-shaped plate, making the overall structure of the arc-shaped plate more stable, just like building a "reinforcement rib" inside the arc-shaped plate, effectively preventing the arc-shaped plate from deforming or bending under heavy pressure, thereby improving the support capacity and stability of the support device on the support surface.

[0017] Furthermore, the wiring harness of the pressure sensor is passed through the wiring groove of the arc-shaped support beam, so that the wiring harness of each pressure sensor can be arranged in an orderly manner according to a certain path, the overall appearance of the device is neater, and it is convenient to quickly locate and deal with problems related to the wiring harness.

[0018] Furthermore, the opening of the wire threading groove can be closed by an inner wall of the installation groove, thereby forming a relatively closed space to accommodate the wiring harness of the pressure sensor, comprehensively protecting the wiring harness, ensuring its normal operation, and extending the service life of the wiring harness.

[0020] Furthermore, an alarm light is used as an alarm, which can alert the operator by flashing the light, and its warning effect is more intuitive and direct.

[0021] Furthermore, the support connecting plates realize the connection between adjacent connecting plates by setting receiving bosses, overlapping bosses and matching first connecting columns, second connecting columns and connecting rings. This structural design makes the connection between adjacent connecting plates no longer rely solely on simple plane fitting, but forms a multi-level, multi-component coordinated and stable connection method through the overlapping of bosses and the cooperation of connecting columns and connecting rings; and the length of the arc plate can be flexibly adjusted by increasing or decreasing the number of middle connecting plates to adapt to the requirements of support surfaces of different sizes.

[0022] Furthermore, a sensor mounting groove is provided on the support connecting plate to place the pressure sensor, providing a relatively independent and protected space for the pressure sensor; since the sensing end of the pressure sensor abuts against the corresponding side of the adjacent support connecting plate, this direct abutment method ensures the stability and accuracy of pressure transmission.

[0036] The purpose of the utility model is to provide a support device to solve the problems existing in the prior art, improve the efficiency of support work, reduce the labor intensity of workers, and be able to sense changes in support strength.

[0037] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0038] Example 1

[0039] This embodiment provides a support device, including but not limited to tunnel support in coal mines, etc. Figures 1 to 5As shown, it includes multiple support connecting plates and four hydraulic support mechanisms 10; each adjacent support connecting plates can be rotatably connected; each support connecting plate is connected to form an arc plate, and the outer top of the arc plate is used to support the support surface; the hydraulic support mechanism 10 has a lifting end that can be raised and lowered in the vertical direction; the two ends of the support connecting plate located at the end are respectively rotatably connected to the lifting end of a hydraulic support mechanism 10; a movable gap is provided between two adjacent support connecting plates, and the movable gap can make each support connecting plate close to or away from the adjacent support connecting plate; a pressure sensor is provided in the movable gap.

[0040] By adopting multiple support connecting plates to form an arc-shaped plate for supporting the support surface, each support connecting plate can be connected more tightly to each other due to the increase of top pressure, thereby improving the support pressure bearing capacity and ensuring the support effect; and during support, the support operation can be completed by four hydraulic support mechanisms 10, reducing manual operation and reducing labor intensity; the pressure sensor arranged in the movable gap between each two adjacent support connecting plates can monitor the top pressure condition.

[0041] Among them, the relevant setting instructions for the support connecting plate:

[0042] Among the optional solutions of this embodiment, it is more preferred that Figures 1 to 5 As shown, the supporting connecting plate includes a plurality of middle connecting plates 30 connected in sequence and a first side connecting plate 20 and a second side connecting plate 40 located at both ends of the whole formed by each middle connecting plate 30; a receiving boss 32 is fixedly provided on one side of the middle connecting plate 30, and a lap boss 31 is fixedly provided on the other side of the middle connecting plate 30; a lap boss 31 is fixedly provided on one side of the first side connecting plate 20; and a receiving boss 32 is fixedly provided on one side of the second side connecting plate 40; the first side connecting plate The thickness of the plate 20 and the second side connecting plate 40 is consistent with the thickness of the middle connecting plate 30, and the thickness of the overlapping boss 31 and the receiving boss 32 are both half the thickness of the middle connecting plate 30; the overlapping boss 31 can be overlapped on top of the receiving boss 32, and the two ends of the receiving boss 32 are respectively fixed with first connecting columns 33, and the overlapping boss 31 is provided with second connecting columns 34 at the position corresponding to each first connecting column 33, and the first connecting column 33 and the second connecting column 34 on the same side are provided with a connecting ring 35. The support connecting plates are connected to each other by setting receiving bosses 32, overlapping bosses 31 and matching first connecting columns 33, second connecting columns 34 and connecting rings 35. This structural design makes the connection between adjacent connecting plates no longer rely solely on simple plane fitting, but forms a multi-level, multi-component coordinated stable connection method through the overlapping of bosses and the cooperation of connecting columns and connecting rings 35; and the length of the arc plate can be flexibly adjusted by increasing or decreasing the number of middle connecting plates 30 to adapt to the requirements of support surfaces of different sizes.

[0043] Specifically, the first connecting column 33 and the second connecting column 34 are both bolts, and threaded holes are set at corresponding positions on the first side connecting plate 20, the middle connecting plate 30 and the second side connecting plate 40; the connecting ring 35 is a component formed by opening an oblong hole on the connecting plate.

[0044] Specifically, the number of the middle connecting plates 30 can be set according to actual needs.

[0045] Among the optional solutions of this embodiment, it is more preferred that Figure 1 As shown, a sensor receiving groove 36 is provided on one side of the support connecting plate near the movable gap. A pressure sensor is installed in the sensor receiving groove 36, and the sensing end of the pressure sensor abuts the corresponding side of the adjacent support connecting plate. Providing sensor receiving groove 36 on the support connecting plate to accommodate the pressure sensor provides a relatively independent and protected space for the pressure sensor. Because the sensing end of the pressure sensor abuts the corresponding side of the adjacent support connecting plate, this direct abutment ensures stable and accurate pressure transmission.

[0046] Among the optional solutions of this embodiment, it is more preferred that Figure 3 and Figure 5 As shown, the curved plate is provided with a mounting groove, in which a curved support beam 50 is provided. The curved support beam 50 is provided in the mounting groove of the curved plate, making the overall structure of the curved plate more stable, just like building a "reinforcement rib" inside the curved plate, effectively preventing the curved plate from deforming or bending under heavy pressure, thereby improving the support capacity and stability of the support device on the support surface.

[0047] Specifically, the mounting grooves on the arc-shaped plate are formed by the small mounting grooves 37 respectively provided on the first side connecting plate 20 , each middle connecting plate 30 and the second side connecting plate 40 .

[0048] Among the optional solutions of this embodiment, it is more preferred that Figure 3 As shown, the arcuate support beam 50 is provided with a wire channel through which the wiring harnesses of each pressure sensor are routed. This allows the wiring harnesses of each pressure sensor to be arranged in an orderly manner along a specific path, making the overall appearance of the device neater and facilitating quick identification and resolution of wiring harness-related issues.

[0049] Among them, the relevant setting description of the hydraulic support mechanism 10 is as follows:

[0050] Specifically, the hydraulic support mechanism 10 may be an existing hydraulic telescopic cylinder component, which is controlled by a hydraulic system to achieve telescopic movement.

[0051] Specifically, such as Figure 1As shown, each hydraulic support mechanism 10 is set on the ground during use, and can be adjusted according to the ups and downs of the ground or the different support heights.

[0052] Among them, about other related settings:

[0053] In the optional solution of this embodiment, it is more preferred to further include an alarm, which is communicatively connected to each pressure sensor. The setting of the alarm can provide an early warning of the bearing pressure. When it exceeds the set threshold, the alarm can be used to provide an early warning, thereby improving safety.

[0054] In the optional solution of this embodiment, it is more preferred that the alarm is an alarm light. Using an alarm light as the alarm can prompt the operator by flashing the light, and its warning effect is more intuitive and direct.

[0055] Among the optional solutions of this embodiment, it is more preferred that Figure 3 As shown, the opening of the wire trough can be closed by one of the inner side walls of the mounting slot. This creates a relatively enclosed space to accommodate the pressure sensor's wiring harness, providing comprehensive protection for the harness, ensuring its proper operation and extending its service life.

[0056] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
