Description

Technical Field

[0001] This invention relates to the field of mining machinery lifting equipment technology, and in particular to a hydraulic support lifting and moving platform suitable for use inside containers. Background Technology

[0002] Existing container hoisting equipment has limited operating conditions, and traditional loading and unloading methods rely heavily on manual labor or simple mechanical devices, which are inefficient and pose safety hazards.

[0003] Chinese patent document CN217947488U discloses a container-embedded telescopic boom, comprising: a fixing device for connecting to the container and providing support; a telescopic boom connected to the fixing device via a sliding assembly, the telescopic boom being telescopically movable; an adapter with a connecting end for connection function; and an adjustment mechanism connected to the telescopic boom via the adjustment mechanism, the height of which can be adjusted. The fixing device is an adapter beam for mounting on the top of the container; the sliding assembly includes a pulley rail comprising multiple sets of pulleys, mounted on the fixing device; the telescopic boom is telescopically mounted on the pulley rail. The telescopic boom has pulley grooves, and the telescopic boom is connected to the pulley rail via these grooves. The adjustment mechanism includes: a movable pulley mounted on the adapter; a fixed pulley mounted on the telescopic boom; a cable winding device mounted on the telescopic boom; and a steel cable, one end of which is fixed to the telescopic boom, and the other end passes sequentially over the movable pulley on the adapter and the fixed pulley on the telescopic boom before connecting to the cable winding device. The cable winding device pulls the steel cable, thus enabling the adapter to move up and down. The cable winding device is a winch. The defects and shortcomings of the container-embedded telescopic boom are as follows: (1) The adjustment mechanism of the container-embedded telescopic boom is to lift objects through a winch, traction steel cable and pulley block, so the lifting capacity is small and it cannot lift large mining machinery; (2) The container-embedded telescopic boom is installed on the top of the container through a transfer beam, and the lower part of the transfer beam is connected to the telescopic boom through a sliding component. In other words, the container-embedded telescopic boom is suspended on the top of the container. When lifting heavy hydraulic supports, there is a risk of falling; (3) The lifting and moving distance of the container-embedded telescopic boom is limited. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a hydraulic support lifting mobile platform suitable for the interior of a container, which solves the technical problem that the existing container-embedded telescopic boom has a small lifting capacity and cannot lift medium and large mining machinery.

[0006] (2) Technical solution

[0007] To achieve the above objectives, the main technical solutions adopted by the present invention include:

[0008] This invention provides a hydraulic support lifting and moving platform suitable for use inside containers, including a main support frame, at least four hydraulic cylinders, chains, and hooks;

[0009] The main support includes at least two upper crossbeams extending in the front-to-back direction, at least two lower crossbeams extending in the front-to-back direction, at least two fixed crossbeams extending in the left-to-right direction, and at least four columns extending in the vertical direction. The upper crossbeams, lower crossbeams, fixed crossbeams, and columns are welded together to form a cuboid frame. The interior of the cuboid frame is used to accommodate the hydraulic support. The lower ends of the at least four columns are equipped with traveling mechanisms. Hydraulic cylinders are installed on the upper parts of the columns located at the four side edges of the cuboid frame. The piston rod of each hydraulic cylinder is connected to a chain, and the end of each chain away from the hydraulic cylinder is connected to a hook. The at least four hooks can hook onto four positions on the base of the hydraulic support.

[0010] Optionally, the length of the upper crossbeam is 2900-3000mm, the length of the fixed crossbeam is 1800-2050mm, the length of the column is 1500-1700mm, the cylinder diameter of the hydraulic cylinder is 90-110mm, and the stroke is 600-800mm.

[0011] Optionally, the hydraulic support hoisting mobile platform also includes a main control valve moving platform, which integrates a hydraulic pump station and a reversing valve group;

[0012] The oil supply and return ports of the hydraulic pump station are connected one-to-one with the corresponding oil ports of the directional valve group. The directional valve group includes multiple directional valves, which are connected to each hydraulic cylinder through hoses. This allows the hydraulic oil output from the hydraulic pump station to enter each hydraulic cylinder after being regulated by the directional valve group, thereby controlling the movement of each hydraulic cylinder. Furthermore, a two-way hydraulic lock is installed on the pipeline between the directional valve and the hydraulic cylinder to keep the hydraulic cylinder in a stationary state.

[0013] Optionally, two hydraulic cylinders located on the front side of the main support are connected in parallel and synchronously controlled by a reversing valve; two other hydraulic cylinders located on the rear side of the main support are connected in parallel and synchronously controlled by another reversing valve.

[0014] Optionally, the directional valve assembly is a manually pilot-operated hydraulic directional valve assembly. The hydraulic support hoisting and moving platform also includes a main control valve moving platform, which integrates a hydraulic pump station 6 and a directional valve assembly. The directional valve assembly is a manually pilot-operated hydraulic directional valve assembly.

[0015] The oil supply and return ports of the hydraulic pump station are connected one-to-one with the corresponding oil ports of the manual pilot-operated hydraulic directional valve assembly. The manual pilot-operated hydraulic directional valve assembly is connected to each hydraulic cylinder through hoses, so that the hydraulic oil output from the hydraulic pump station enters each hydraulic cylinder after being regulated by the manual pilot-operated hydraulic directional valve assembly to control the movement of each hydraulic cylinder. Furthermore, a two-way hydraulic lock is installed on the pipeline between the manual pilot-operated hydraulic directional valve assembly and each hydraulic cylinder to keep the hydraulic cylinder in a stationary state.

[0016] Optionally, the manual pilot-operated hydraulic directional valve assembly includes a valve body, a manual pilot valve, a first fixed rod, a second fixed rod, a rotating shaft, and an L-shaped guard plate;

[0017] The valve body has multiple main valve cores that slide inside, and multiple manual pilot valves on the side of the valve body. Each manual pilot valve controls one main valve core. Each manual pilot valve has a lever on its upper part. A first fixed rod and a second fixed rod are respectively set on both sides of the multiple manual pilot valves. One end of the first fixed rod and the second fixed rod are fixedly connected to the valve body, and the other end of the first fixed rod and the second fixed rod are rotatably supported by a rotating shaft. The rotating shaft is connected to an L-shaped protective plate, so that the L-shaped protective plate can rotate between the open position and the closed position. When the L-shaped protective plate is in the closed position, the L-shaped protective plate covers the outer periphery of the levers of all manual pilot valves, thereby preventing accidental operation of the levers.

[0018] Optionally, the L-shaped guard plate includes a first plate and a second plate connected together, the fixed end of the first plate being connected to a rotating shaft, and the space between the first plate and the second plate being used to accommodate the paddles of all manual pilot valves when the L-shaped guard plate is in the closed position.

[0019] Optionally, the first fixing rod has a stepped hole at the end near the manual pilot valve. The stepped hole has a first section facing the L-shaped guard plate and a second section facing away from the L-shaped guard plate. The diameter of the first section is larger than the diameter of the second section. The second fixing rod has a through hole at the end near the manual pilot valve. The side of the second fixing rod facing the L-shaped guard plate has at least two limiting grooves along the radial direction of the through hole. A compression spring is provided in the first section.

[0020] Both ends of the rotating shaft are provided with stepped surfaces to form a stepped shaft. One end of the rotating shaft is rotatably supported on the through hole, and the other end of the rotating shaft passes through the compression spring and is rotatably supported in the second hole section. When the L-shaped guard plate is facing one of the limiting grooves, the compression spring can drive the rotating shaft to move axially. The axial movement of the rotating shaft will cause the L-shaped guard plate to be inserted into the limiting groove, so that the L-shaped guard plate is kept in the open or closed position.

[0021] Optionally, the manually pilot-operated hydraulic directional valve assembly also includes a locking mechanism;

[0022] A locking mechanism is provided on the outer side of the second fixed rod corresponding to the shaft mounting area. The end of the shaft near the locking mechanism passes through the second fixed rod and connects to the locking mechanism, thereby enabling the locking mechanism to selectively position the shaft axially.

[0023] Optionally, the hydraulic support hoisting mobile platform also includes a controller, personnel detection sensors, and warning lights;

[0024] The controller is connected to the personnel detection sensor and the warning light. The detection sensor is mounted on the main support, and the controller and the warning light are mounted on the main control valve moving platform. The personnel detection sensor can detect personnel information around the main support and send the personnel information to the controller. The controller determines whether the number of people is 0: if yes, the controller controls the warning light to turn off; if no, the controller controls the warning light to turn on.

[0025] (III) Beneficial Effects

[0026] The beneficial effects of the present invention are as follows: The hydraulic support hoisting and moving platform applicable to the interior of a container includes a main support, at least four hydraulic cylinders, chains, and hooks; the main support includes at least two upper crossbeams extending in the front-to-back direction, at least two lower crossbeams extending in the front-to-back direction, at least two fixed crossbeams extending in the left-to-right direction, and at least four columns extending in the vertical direction. The upper crossbeams, lower crossbeams, fixed crossbeams, and columns are welded together to form a cuboid frame. The interior of the cuboid frame is used to accommodate the hydraulic support. The lower ends of the at least four columns are equipped with a traveling mechanism. Hydraulic cylinders are installed on the upper parts of the columns located at the four side edges of the cuboid frame. The piston rod end of each hydraulic cylinder is connected to a chain, and the end of each chain away from the hydraulic cylinder is connected to a hook. The at least four hooks can respectively hook onto four positions on the base of the hydraulic support. Compared to existing container-embedded telescopic booms, this device uses a main support frame and hydraulic cylinders to lift hydraulic supports. It has a compact structure and strong load-bearing capacity, which not only improves the efficiency of loading and unloading hydraulic supports inside containers, but also allows for precise hydraulic control of the lifting force. This ensures the safety of the lifting operation and effectively avoids safety hazards, making it suitable for lifting operations of hydraulic supports inside containers. Attached Figure Description

Detailed Implementation

[0043] To better explain and facilitate understanding of the present invention, a detailed description of the invention is provided below with reference to the accompanying drawings and specific embodiments. In this document, directional terms such as "upper," "lower," "left," "right," "front," and "rear" are used interchangeably. Figure 1 The orientation is used as a reference.

[0044] Example 1:

[0045] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This embodiment provides a hydraulic support hoisting mobile platform suitable for use inside containers.

[0046] Specifically, the hydraulic support lifting and moving platform suitable for use inside containers includes a main support 1, at least four hydraulic cylinders 2, a chain 3, and a hook 4.

[0047] The main support 1 includes at least two upper crossbeams 101 extending in the front-to-back direction, at least two lower crossbeams 102 extending in the front-to-back direction, at least two fixed crossbeams 103 extending in the left-to-right direction, and at least four columns 104 extending in the vertical direction. The upper crossbeams 101, lower crossbeams 102, fixed crossbeams 103, and columns 104 are welded together to form a cuboid frame. The interior of the cuboid frame is used to accommodate the hydraulic support 5. Hydraulic cylinders 2 are installed on the upper part of the columns 104 located at the four side edges of the cuboid frame. A chain 3 is connected to the end of the piston rod of each hydraulic cylinder 2. A hook 4 is connected to the end of each chain 3 away from the hydraulic cylinder 2. The four hooks 4 can hook onto four positions on the base of the hydraulic support 5 respectively.

[0048] Of course, to improve the load-bearing capacity of the cuboid frame, the number of columns 104 can be greater than four. For example, there can be six columns 104, with three columns 104 arranged on the left side of the cuboid frame and the other three columns 104 arranged on the right side of the cuboid frame; hydraulic cylinders 2 are installed on the upper part of the columns 104 located at the four side edges of the cuboid frame, or hydraulic cylinders 2 are installed on the upper part of all six columns 104, and the piston rod of each hydraulic cylinder 2 is connected to a chain 3 and a hook 4.

[0049] This embodiment describes a hydraulic support lifting and moving platform suitable for use inside containers. Due to its structure, it simplifies operation and improves the efficiency of loading and unloading hydraulic supports inside containers by using the main support 1 and hydraulic cylinders 2 to lift the hydraulic supports 5. Furthermore, the hydraulic cylinders 2 are hydraulically operated, allowing for precise control of the lifting force and ensuring operational safety. In addition, the hydraulic support lifting and moving platform has a compact design, strong load-bearing capacity, and effectively avoids safety hazards, making it suitable for lifting hydraulic supports inside containers.

[0050] Specifically, two upper crossbeams 101 and multiple fixed crossbeams 103 are welded together to form a rectangular frame. Columns 104 are welded to the four corners of the rectangular frame, and lower crossbeams 102 are welded to the outer sides of the two columns 104 located on the left or right side of the main support 1, thereby forming a cuboid frame.

[0051] Furthermore, the main support frame 1 is made of Q235A-δ20 or higher material. Q235A-δ20 or higher material refers to the material properties of Q235A steel when the thickness reaches or exceeds 20 mm.

[0052] Furthermore, the running gear 105 is either a wheeled running gear or a tracked running gear. For example, the running gear 105 is a remotely controlled electric tank.

[0053] Furthermore, the hook 4 has a load capacity of 8T, and the chain 3 has a load capacity of 10T. The hydraulic cylinder 2 has a cylinder diameter of 90-110mm, a stroke of 600-800mm, and a load capacity of 10T.

[0054] Furthermore, the length of the upper crossbeam 101 is 2900-3000mm, the length of the fixed crossbeam 103 is 1800-2050mm, and the length of the column 104 is 1500-1700mm.

[0055] See Figure 6 and Figure 7 The hydraulic support hoisting and moving platform in this embodiment also includes a main control valve moving platform, which integrates a hydraulic pump station 6 and a reversing valve group 7.

[0056] The oil supply port and oil return port of the hydraulic pump station 6 are connected one-to-one with the corresponding oil ports of the directional valve group 7. The directional valve group 7 includes multiple directional valves 701. The multiple directional valves 701 are connected to each hydraulic cylinder 2 through hoses, so that the hydraulic oil output by the hydraulic pump station 6 enters each hydraulic cylinder 2 after being regulated by the directional valve group 7, so as to control the action of each hydraulic cylinder 2. Furthermore, a two-way hydraulic lock 8 is installed on the pipeline between the directional valve 701 and the hydraulic cylinder 2 to keep the hydraulic cylinder 2 in a stationary state.

[0057] It should be noted that the main control valve moving platform can be moved to a safe area for operation to avoid confined space work and ensure the safety of operators. Furthermore, the hose specification is DN10, and the length of the hose can be adjusted according to the dimensions of the main support 1.

[0058] Specifically, the two-way hydraulic lock 8 utilizes hydraulic principles to lock hydraulic oil within a volume, thereby allowing the actuator to remain stationary for a longer period of time. It essentially consists of two hydraulically controlled check valves 701. Each check valve 701 takes the pressure from the other's oil circuit as pilot oil. When one circuit has no pressure, the other closes simultaneously, thus allowing the hydraulic cylinder 2 to be selectively locked.

[0059] Furthermore, the two hydraulic cylinders 2 located at the front are connected in parallel and synchronously controlled by a reversing valve 701; the other two hydraulic cylinders located at the rear are connected in parallel and synchronously controlled by another reversing valve 701. The purpose of this arrangement is that when hoisting the hydraulic support 5, the two hydraulic cylinders 2 located at the front first hoist the front part of the base of the hydraulic support 5; then, the other two hydraulic cylinders located at the rear hoist the rear part of the base of the hydraulic support 5, thereby improving the safety of the hoisting and reducing safety hazards.

[0060] Furthermore, in this embodiment, the directional valve 701 is an electromagnetic directional valve, preferably a three-position four-way electromagnetic directional valve. This three-position four-way electromagnetic directional valve has three operating positions and four ports (two inlet and two outlet). Each three-position four-way electromagnetic directional valve controls two hydraulic cylinders 2. The electromagnetic directional valve can control the flow direction of hydraulic oil by being energized and de-energized, thereby controlling the movement of the hydraulic cylinders 2.

[0061] Example 2:

[0062] See Figure 8 and Figure 9 This embodiment provides another hydraulic support hoisting mobile platform suitable for the interior of a container. The difference from embodiment 1 is that the reversing valve group 7 in this embodiment is a manual pilot-operated hydraulic reversing valve group. The manual pilot-operated hydraulic reversing valve group includes a valve body 9, a manual pilot valve 10, a first fixed rod 12, a second fixed rod 13, a rotating shaft 14, and an L-shaped guard plate 15.

[0063] Multiple main valve cores are slidably mounted inside the valve body 9. Multiple manual pilot valves 10 are mounted on the side of the valve body 9, each controlling one main valve core. Each manual pilot valve 10 has a lever 11 on its upper part. A first fixing rod 12 and a second fixing rod 13 are respectively mounted on both sides of each manual pilot valve 10. One end of each fixing rod 12 and the second fixing rod 13 is fixedly connected to the valve body 9, while the other end rotatably supports a rotating shaft 14. The rotating shaft 14 is connected to an L-shaped guard plate 15, allowing the L-shaped guard plate 15 to rotate between an open and closed position. When the L-shaped guard plate 15 is in the closed position, it covers the levers 11 of all the manual pilot valves 10, preventing accidental operation of the levers 11. It should be noted that the operator generates control oil pressure by manually operating the manual pilot valves 10, thereby driving the main valve cores inside the valve body 9 to switch the fluid flow direction in the hydraulic system.

[0064] The manual pilot-operated hydraulic directional valve assembly of this embodiment can block the operating direction of the lever 11 through the L-shaped guard plate 15, thereby preventing the operator from misoperating the manual pilot-operated hydraulic directional valve assembly and preventing misoperation caused by falling objects accidentally colliding with the operating lever 11. This significantly improves the anti-misoperation performance of the manual pilot-operated hydraulic directional valve assembly, and thus improves the safety performance of the hydraulic support hoisting mobile platform that uses the manual pilot-operated hydraulic directional valve assembly as the main control component.

[0065] Specifically, the L-shaped guard plate 15 includes a first plate and a second plate connected together. The fixed end of the first plate is connected to the rotating shaft 14. The space between the first plate and the second plate is used to accommodate the paddles 11 of all manual pilot valves 10 when the L-shaped guard plate 15 is in the closed position.

[0066] Furthermore, the first fixing rod 12 and the second fixing rod 13 are detachably connected to the valve body 9 by bolts 17. Preferably, the bolts 17 are M10 hexagonal head bolts, which can be disassembled and assembled using common tools, thus providing both reliable safety and ease of transportation, maintenance, and use. The M10 hexagonal head bolts are preferably made of stainless steel S30408 ​​(06Cr19Ni10). Alternatively, hexagonal socket head cap screws can be used instead of M10 hexagonal head bolts. In this case, the hexagonal socket wrench used by the operator during maintenance is lighter and smaller than that of a hexagonal head bolt, reducing the workload of maintenance personnel.

[0067] Furthermore, the outer surface of the L-shaped guard plate 15 in this embodiment is brushed to form a satin finish. The satin finish not only improves the appearance quality of the L-shaped guard plate 15, but also reduces surface roughness and enhances wear resistance and corrosion resistance.

[0068] See Figure 10 , Figure 11, Figure 12 and Figure 13 As shown, the first fixing rod 12 has a stepped hole 18 at one end near the manual pilot valve 10. The stepped hole 18 has a first section facing the L-shaped guard plate 15 and a second section facing away from the L-shaped guard plate 15. The diameter of the first section is larger than the diameter of the second section. The second fixing rod 13 has a through hole 20 at one end near the manual pilot valve 10. The side of the second fixing rod 13 facing the L-shaped guard plate 15 has at least two limiting grooves 21 along the radial direction of the through hole 20. A compression spring 16 is provided in the first section.

[0069] Both ends of the rotating shaft 14 are provided with stepped surfaces to form a stepped shaft. One end of the rotating shaft 14 is rotatably supported on the through hole 20, and the other end of the rotating shaft 14 passes through the compression spring 16 and is rotatably supported in the second hole section. When the L-shaped guard plate 15 is facing one of the limiting grooves 21, the compression spring 16 can drive the rotating shaft 14 to move axially. The axial movement of the rotating shaft 14 will drive the L-shaped guard plate 15 to be inserted into the limiting groove 21, so that the L-shaped guard plate 15 is kept in the open or closed position.

[0070] It should be noted that the L-shaped guard plate 15 and the rotating shaft 14 can have an axial displacement of 3-5mm. The operator can push the L-shaped guard plate 15 to pull it out of the limiting groove 21 and then perform the rotation operation.

[0071] Preferably, the L-shaped guard plate 15 and the rotating shaft 14 are welded together, and during welding, the end of the L-shaped guard plate 15 near the limiting groove 21 extends 3mm beyond the step of the rotating shaft 14. This arrangement allows the L-shaped guard plate 15 to engage with the limiting groove 21 on the second fixing rod 13, thereby limiting the L-shaped guard plate 15 and preventing it from rotating on its own under its own weight or other interference factors, thus avoiding distraction and disruption to normal operation.

[0072] Preferably, the first fixing rod 12 and the second fixing rod 13 are made of stainless steel S30408 ​​(06Cr19Ni10) material, with a thickness of 10-14mm, a width of 18-22mm, and a length of 180-190mm. Stainless steel material is widely available and easy to obtain, and the first fixing rod 12 and the second fixing rod 13 have advantages such as light weight, small size, ease of manufacture, ease of installation, and ease of maintenance.

[0073] Specifically, the bolt fixing holes at the rear ends of the first fixing rod 12 and the second fixing rod 13 are φ10.5mm circular holes, while the bolt fixing hole in the middle is an oblong hole with an arc radius R of 5.25mm at both ends and a center distance of 3.5mm between the two arcs. This design achieves a secure installation while accommodating larger machining errors in the bolt fixing holes on the side of the valve body 9, improving the adaptability of the first fixing rod 12 and the second fixing rod 13, and reducing the machining difficulty of the first fixing rod 12 and the second fixing rod 13.

[0074] Preferably, the front end of the first fixing rod 12 is rounded with a radius of 10mm. The first section of the stepped hole 18 on the first fixing rod 12 has a diameter of 11.5mm and a depth of 5mm, while the second section has a diameter of φ8mm and a depth of 7mm. The first section serves as a spring guide sleeve for fixing the compression spring 16, and the second section serves as a hard friction bearing seat for the rotating shaft 14. To prevent the compression spring 16 from rubbing against the edge of the first section, a guide slope 19 is provided on the edge of the first section. When the compression spring 16 is compressed, the guide slope 19 guides the compression spring 16, allowing it to slide into the first section.

[0075] Preferably, the front end of the second fixing rod 13 is rounded with a radius of 10mm. The through hole 20 on the second fixing rod 13 serves as a hard friction bearing seat for the rotating shaft 14, and its diameter is 8mm. The limiting groove 21 serves as a limiting slot for the L-shaped guard plate 15, with a groove width of 3.5mm, a groove depth of 4mm, and its center line passing through the center of the through hole 20. The number of limiting grooves 21 can be two or more; in this embodiment, the number of limiting grooves 21 is two.

[0076] Preferably, the rotating shaft 14 is made of stainless steel S30408 ​​(06Cr19Ni10) round steel. The rotating shaft 14 has a diameter of 12mm and a length of 247mm, with its diameter tapered to 7.5mm at both ends. The tapered portion at the left end is 15mm long, and the tapered portion at the right end is 22mm long. The tapered portion at the left end mates with the front end of the second fixing rod 13, the tapered portion at the right end serves as a spring guide shaft, and the other portion mates with the front end of the first fixing rod 12. This allows the rotating shaft 14 to be confined between the first fixing rod 12 and the second fixing rod 13, and to rotate flexibly around the common axis of the stepped hole 18 and the through hole 20.

[0077] Preferably, the compression spring 16 is a cylindrical helical compression stainless steel spring, which can push the rotating shaft 14 and the L-shaped guard plate 15 towards the second fixing rod 13 when the L-shaped guard plate 15 is aligned with the limiting groove 21, thereby limiting the L-shaped guard plate 15. In this embodiment, a stainless steel compression spring made of stainless steel S30408 ​​(06Cr19Ni10) spring steel wire is used. To ensure the limiting effect and facilitate the operator to adjust the limiting position of the L-shaped guard plate 15, the elastic force of the compression spring 16 in the working position should be between 10-130N. According to the structural characteristics of the embodiment, the outer diameter of the spring needs to be <11.5mm, the inner diameter of the spring needs to be >7.5mm, and the length of the spring when working should be between 15-18mm. Therefore, a spring made of 1.5mm diameter stainless steel S30408 ​​(06Cr19Ni10) spring steel wire was selected, with an inner diameter of 8mm, a mean diameter of 9.5mm, and an outer diameter of 11mm. The spring length in the free state is 22mm, and the spring length in the working state is 15-18mm. The spring force in the working state is 35.92-62.68N, which has a good effect.

[0078] Preferably, the L-shaped guard plate 15 is made of 3mm thick stainless steel S30408 ​​(06Cr19Ni10) by bending. After bending, the length of the long side is 72mm, the length of the short side is 50mm, and the bending radius is 15mm.

[0079] See Figure 14 The manual pilot-operated hydraulic directional valve assembly of this embodiment also includes a locking mechanism 22. The locking mechanism 22 is provided on the outer side of the second fixing rod 13 corresponding to the mounting area of ​​the rotating shaft 14. The end of the rotating shaft 14 near the locking mechanism 22 passes through the second fixing rod 13 and is connected to the locking mechanism 22, thereby enabling the locking mechanism 22 to selectively position the rotating shaft 14 axially.

[0080] Furthermore, the locking mechanism 22 is a key lock, combination lock, or magnetic lock, and the end of the rotating shaft 14 is provided with an annular groove along the circumference. The locking tongue inside the locking mechanism 22 can be selectively engaged with the annular groove.

[0081] In this embodiment, the manually piloted hydraulic directional valve assembly employs a locking mechanism 22. The L-shaped guard plate 15 achieves dual locking through physical isolation and mechanical interlocking, namely unlocking and rotation, which further reduces operator error.

[0082] Furthermore, the hydraulic support hoisting mobile platform also includes a controller, a personnel detection sensor, and a warning light. The controller is connected to the personnel detection sensor and the warning light respectively. The detection sensor is installed on the main support 1, and the controller and the warning light are installed on the main control valve moving platform.

[0083] The personnel detection sensor can detect personnel information around the main support 1 and send the personnel information to the controller. The controller determines whether the number of people is 0: if yes, the controller controls the warning light to turn off; if no, the controller controls the warning light to turn on to warn the operator, thereby further improving the safety of hydraulic support hoisting.

[0084] This embodiment also provides a method for using the above-mentioned hydraulic support hoisting mobile platform, including the following steps:

[0085] S1. Start the traveling mechanism 105. The traveling mechanism 105 drives the main support 1 to approach the hydraulic support 5 to be hoisted. When the main support 1 covers the outside of the hydraulic support 5, stop the traveling mechanism 105.

[0086] S2. Operate the reversing valve group 7, and then start the hydraulic pump station 6. The hydraulic pump station 6 drives the piston rod of the hydraulic cylinder 2 to extend, so that the hook 4 at the lower end of the chain 3 approaches the hydraulic support 5; then, the hook 4 hooks the base of the hydraulic support 5.

[0087] S3. Operate the reversing valve group 7, and then start the hydraulic pump station 6. The hydraulic pump station 6 drives the piston rod of the hydraulic cylinder 2 to retract, thereby driving the chain 3, hook 4 and hydraulic support 5 to move upward, so as to achieve the purpose of lifting the hydraulic support 5.

[0088] S4. Start the walking mechanism 105. The walking mechanism 105 drives the main support 1 carrying the hydraulic support 5 to approach the container. After the main support 1 enters the container, stop the walking motor 105.

[0089] S5. Operate the reversing valve group 7, then start the hydraulic pump station 6. The hydraulic pump station 6 drives the piston rod of the hydraulic cylinder 2 to extend, thereby driving the chain 3, hook 4 and hydraulic support 5 to move downward and place the hydraulic support 5 inside the container; then, release the hook 4 from the restriction of the hydraulic support 5.

[0090] S6. Start the traveling mechanism 105. The traveling mechanism 105 drives the main support 1 to move to the outside of the container to complete the hoisting operation of the hydraulic support 5.
