Description

Technical Field

[0001] This utility model relates to the field of hydraulic support technology, specifically a remote-controlled tracked advanced support hydraulic support. Background Technology

[0002] Hydraulic supports are key equipment used in underground engineering projects such as coal mining for roadway or working face support. They utilize a hydraulic system to drive actuators such as columns and jacks to achieve the lifting, moving, and balancing adjustment of structures such as roof beams and shield beams. This device can dynamically adapt to changes in roof pressure, providing active support to prevent roof collapse accidents.

[0003] In existing technologies, the operation of traditional hydraulic supports usually requires operators to be in close contact with the equipment, which exposes them to significant safety risks. At the same time, traditional equipment is insufficient in terms of operational stability and adaptability to complex terrain. It is prone to failure or safety accidents when operating under complex geological conditions, and its adaptability to floor undulations is also poor. Moreover, traditional supports lack the ability to flexibly cope with complex geological conditions and coal mining environments, making it difficult to quickly switch working states to reduce lateral stress impacts. They cannot effectively resist dynamic loads during coal mining operations, which affects the service life of the equipment and results in poor operational safety and adaptability, making it difficult to meet the needs of various complex coal mining environments such as small and confined coal mines. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a remote-controlled tracked advanced support hydraulic support. This solves the problems mentioned in the background section, where traditional hydraulic support operation typically requires operators to be in close proximity to the equipment, exposing them to significant safety risks. Furthermore, traditional equipment suffers from deficiencies in operational stability and adaptability to complex terrain, making it prone to malfunctions or accidents under complex geological conditions and exhibiting poor adaptability to uneven floor surfaces. Moreover, traditional supports lack the ability to flexibly respond to complex geological conditions and coal mining environments, struggle to quickly switch working states to reduce lateral stress impacts, and are unable to effectively resist dynamic loads during coal mining operations. This results in reduced equipment lifespan, poor operational safety and adaptability, and an inability to meet the needs of various complex coal mining environments, such as those in confined spaces like small coal mines.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a remote-controlled tracked advanced support hydraulic support, comprising:

[0008] A base, on the surface of which a bracket controller is mounted, and on both sides of the upper surface of the base, plunger cylinders are mounted, with columns inserted into the inner cavities of the plunger cylinders, and top beams mounted on the tops of the columns.

[0009] A fixed frame is set on the outer periphery of the base. The fixed frame has a U-shaped design. Telescopic hydraulic cylinders are installed at the four bottom corners of the fixed frame. Lifting seats are installed at the output ends of the telescopic hydraulic cylinders. Connecting seats are installed between the lifting seats. The connecting seats are connected to the bottom of the base. Tracks are provided on the outer side of the fixed frame.

[0010] Side support plates are provided on the left and right sides of the connecting seat. Side support cylinders are provided on both the left and right sides of the base, and the output ends of the side support cylinders are connected to the side support plates.

[0011] A drive motor is located inside the track. A drive wheel is installed on one side of the inner cavity of the track, and a driven wheel is installed on the other side of the inner cavity of the track. The output end of the drive motor is connected to the shaft of the drive wheel. A mounting rod is installed on the shaft of the driven wheel, and the mounting rod is connected to the surface of the fixed frame through a bearing.

[0012] Preferably, support plates are installed on both sides of the upper and lower surfaces of the fixing frame, and support seats are installed on the support surfaces of the support plates, which are used to support the tracks.

[0013] Preferably, all the support seats are of the C-shape design, and the inner wall of each support seat is equipped with rollers through bearings. The rollers are in close contact with the inner wall of the track, so that when the support seat supports the track frame, it will not affect the normal rotation of the track, and at the same time, it can improve the overall stability of the track.

[0014] Preferably, the base has limit grooves on both the front and rear sides of its surface, and the base plate has mounting grooves on both the front and rear sides of its top surface. The plunger cylinders are installed inside the limit grooves and mounting grooves, which can improve the stability of the plunger cylinders.

[0015] Preferably, a first connecting block is installed on both the left and right sides of the base, and each side support cylinder is connected to the first connecting block via a rotating shaft. A second connecting block is installed on the upper surface of each side support plate, and the output end of each side support cylinder is connected to the second connecting block via a rotating shaft, so that the side support plate is not obstructed when it is raised or lowered.

[0016] Preferably, the surface of the connecting seat is evenly provided with connecting grooves, and the inner wall of each connecting groove is equipped with a connecting plate through a rotating shaft.

[0017] Preferably, sliding plates are installed on the front and rear of the upper surface of the base plate, and sliding grooves are opened on the upper surface of the fixing frame at the corresponding positions of the sliding plates. The sliding plates are inserted into the sliding grooves, so that the base can be raised and lowered stably.

[0018] Beneficial effects

[0019] Compared with the prior art, this utility model provides a remote-controlled tracked advanced support hydraulic support, which has the following beneficial effects:

[0020] 1. This remote-controlled tracked advanced support hydraulic support, by installing a support controller on the base surface and utilizing remote control technology, allows operators to remotely control the equipment from a safe area away from the work surface, eliminating the need for close contact with the equipment as in traditional methods. This change in operating method directly avoids the potential dangers of personnel having close contact with the equipment, significantly improves the safety of the operation process, and demonstrates the remarkable effects of remote control technology.

[0021] 2. This remote-controlled tracked advanced support hydraulic support adopts a tracked design. A drive motor is installed on the inner side of the track to drive the drive wheel, which in turn drives the track with the driven wheel. The track design allows for a large contact area with the ground during operation, resulting in strong friction and ensuring safer and faster operation. At the same time, the track provides good adaptability to complex terrain, effectively preventing safety accidents caused by equipment failure or improper operation, and also improving the support's adaptability to uneven ground surfaces.

[0022] 3. This remote-controlled tracked advanced support hydraulic support features a piston cylinder and column that can drive the top beam to rise and fall. Activating the telescopic cylinder can raise and lower the lifting seat, which in turn raises and lowers the connecting seat, ultimately raising and lowering the entire base. Simultaneously, the telescopic structure of the side support cylinder and telescopic cylinder allows the side support plate and base to quickly switch working states, maintaining a retracted posture during non-support phases. This reduces the direct impact of lateral stress on the support body under complex geological conditions, extending the equipment's service life. When the telescopic cylinder moves the base downwards to make close contact with the ground, it forms a compact, rigid frame. Combined with the vertical support system formed by the column and top beam, this creates a multi-dimensional force balance structure, effectively resisting dynamic loads generated during coal mining operations. Furthermore, the support controller can intelligently match the timing of the base's retraction and extension, improving operational safety and adaptability in complex geological environments. This allows it to adapt to various complex geological conditions and coal mining environments. These structural and design features work together to make this support highly efficient, safe, and intelligent, making it an ideal choice for small, confined coal mines. Attached Figure Description

[0029] 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.

[0030] This utility model provides a technical solution: a remote-controlled tracked advanced support hydraulic support. (See also...)

Figure 3 Both sides of the upper surface of the base 1 are equipped with plunger cylinders 2, and each plunger cylinder 2 has a column 3 inserted into its inner cavity. A top beam 4 is installed on the top of the column 3.

[0031] Please see Figure 1 The fixing bracket 5 is located on the outer periphery of the base 1. The fixing bracket 5 has a U-shaped design, and telescopic hydraulic cylinders 7 are installed at the four corners of the bottom of the fixing bracket 5. Please refer to [link / reference]. Figure 3 Each of the output ends of the telescopic cylinder 7 is equipped with a lifting seat 8, and a connecting seat 9 is installed between the lifting seats 8. The connecting seat 9 is connected to the bottom of the base 1, and the outer side of the fixed frame 5 is equipped with a track 102.

[0032] Side support plates 10 are provided on the left and right sides of the connecting seat 9. Side support cylinders 11 are provided on both the left and right sides of the base 1. The output ends of the side support cylinders 11 are connected to the side support plates 10.

[0033] Please see Figure 2 The drive motor 14 is located inside the track 102. A drive wheel 12 is installed on one side of the inner cavity of the track 102, and a driven wheel 13 is installed on the other side of the inner cavity of the track 102. The output end of the drive motor 14 is connected to the shaft of the drive wheel 12. A mounting rod 6 is installed on the shaft of the driven wheel 13. The mounting rod 6 is connected to the surface of the fixed frame 5 through a bearing.

[0034] The bracket controller 101 has a built-in Bluetooth slave module, infrared receiver unit, CAN bus interface and hydraulic valve group drive circuit. The hydraulic bracket is equipped with displacement sensor, pressure sensor, attitude sensor and actuator. The operator needs to use a handheld remote terminal to control the hydraulic bracket. The handheld remote terminal integrates Bluetooth host module, infrared transmitter unit, LCD screen, lithium battery power supply module and control buttons.

[0035] Bluetooth control workflow: After the handheld remote terminal is powered on, it performs a power self-test and initializes the Bluetooth host module / infrared transmitter / LCD display.

[0036] The bracket controller 101 synchronously starts and initializes the Bluetooth slave module / infrared receiver unit / CAN bus interface;

[0037] After completing device pairing and authentication via infrared unit, an encrypted Bluetooth connection is established.

[0038] Operators input control commands via terminal buttons;

[0039] The command is transmitted to the bracket controller 101 via Bluetooth.

[0040] After parsing the command, the controller drives the hydraulic valve group to perform the corresponding action;

[0041] During execution, displacement / pressure / attitude sensor data is transmitted back to the terminal display screen in real time via CAN bus, triggering emergency stop or automatically executing preset protection programs in abnormal working conditions;

[0042] By mounting a bracket controller 101 on the surface of the base 1, and utilizing remote control technology, operators can remotely control the equipment from a safe area away from the work surface, without having to be in close proximity to it as in traditional operation methods. This change in operation directly avoids the dangers that personnel may face from close contact with the equipment, significantly improves the safety of the operation process, and demonstrates the remarkable effects of remote control technology.

[0043] The support frame adopts a track 102 design. A drive motor 14 is installed on the inner side of the track 102 to drive the drive wheel 12, which, in conjunction with the driven wheel 13, drives the track 102 to rotate. The design of the track 102 ensures a large contact area with the ground and strong friction during operation, guaranteeing safer and faster operation. Simultaneously, the track 102 exhibits good adaptability to complex terrain, effectively preventing safety accidents caused by equipment failure or improper operation, and also improving the support frame's adaptability to uneven ground surfaces.

[0044] The fixed frame 5 has a U-shaped design, with telescopic hydraulic cylinders 7 installed at the four corners of the bottom.

The starting plunger cylinder 2 and column 3 can drive the top beam 4 to rise and fall, and the starting telescopic cylinder 7 can drive the lifting seat 8 to rise and fall, thereby driving the connecting seat 9 to rise and fall, and then driving the base 1 to rise and fall as a whole. At the same time, the telescopic structure of the side support cylinder 11 and the telescopic cylinder 7 allows the side support plate 10 and the base 1 to quickly switch working states. In the non-support stage, it maintains a retracted posture, reducing the direct impact of lateral stress on the support body under complex geological conditions and extending the service life of the equipment. When the telescopic cylinder 7 drives the base 1 to move downward and make close contact with the ground, it will make the base 1 form a compact rigid frame. Together with the vertical support system formed by the column 3 and the top beam 4, it will build a multi-dimensional force balance structure, effectively resisting the dynamic load generated in coal mining operations. At the same time, the support controller 101 can intelligently match the timing of the base 1's retraction and extension, improving the safety and adaptability of operations in complex geological environments, enabling it to adapt to various complex geological conditions and coal mining environments. These structures and designs work together to make the support highly efficient, safe, and intelligent, making it an ideal choice for small coal mines with limited space.

[0045] Support plates 15 are installed on both sides of the upper and lower surfaces of the mounting bracket 5. Please refer to [link / reference]. Figure 5 Each support surface of the support plate 15 is equipped with a support seat 16, which is used to support the track 102.

[0046] All support seats 16 are of the C-shape design. Rollers 17 are installed on the inner wall of each support seat 16 through bearings. The rollers 17 are in close contact with the inner wall of the track 102, so that when the support seat 16 supports the frame of the track 102, it will not affect the normal rotation of the track 102, and at the same time improve the overall stability of the track 102.

The sliding plate 24 is inserted into the sliding groove 25, so that the base 1 can be raised and lowered stably.

[0051] In operation: A bracket controller 101 is mounted on the surface of base 1. This controller has built-in Bluetooth slave modules and works in conjunction with a hydraulic bracket equipped with various sensors and actuators, controlled by a handheld remote control terminal.

After pairing and authentication via infrared unit, a Bluetooth encrypted connection is established. The operator inputs control commands via terminal buttons, which are transmitted to the bracket controller 101 via Bluetooth. The controller parses the commands and drives the hydraulic valve group to perform corresponding actions. During execution, sensor data is transmitted back to the terminal display screen in real time via the CAN bus. In case of abnormal conditions, a protection program is triggered. During bracket operation, the drive motor… The drive wheel 12, in conjunction with the driven wheel 13, drives the track 102 to rotate.
