Description

Technical Field

[0001] This utility model belongs to the field of mining flatbed trucks, and in particular relates to a flatbed truck used for transporting mining advanced hydraulic supports. Background Technology

[0002] Hydraulic supports are the core support equipment in fully mechanized coal mining faces. Relying on a high-pressure hydraulic system, they achieve functions such as support, movement, and sidewall protection, and are key equipment to ensure safe and efficient underground operations. They mainly consist of components such as a top beam, base, columns, jacks, a hydraulic control system, and sidewall plates. The columns and top beam form a stable support structure, resisting surrounding rock pressure, preventing roof collapse and sidewall spalling, and creating a safe space for coal mining machine operations and personnel passage.

[0003] During operation, the hydraulic pump outputs high-pressure oil to drive the extension and retraction of the support column. The top beam closely adheres to the roof, providing uniform support force, while the side guards promptly protect the soft coal seam in the roadway. The pushing jacks move the entire support forward, simultaneously traction the scraper conveyor to advance synchronously, achieving coordinated operation of support and coal mining. Hydraulic supports are characterized by high support strength, wide support range, flexible operation, and high degree of automation. They can be adapted to different coal seam thicknesses, dip angles, and geological conditions, and are classified into shield type, support type, and support-shield type.

[0004] During the installation of the underground pre-support, the pre-support is placed directly on the flatbed truck and secured with steel wire ropes. During transportation, the vehicle swings greatly, and the loading equipment tilts to the left and right, which can easily cause safety accidents such as the transport vehicle derailing. Utility Model Content

[0005] The purpose of this utility model is to provide a flatbed truck for transporting advanced hydraulic supports for mining, so as to solve the problem that advanced hydraulic supports are prone to sliding forward, backward, left, right, or even overturning during transportation.

[0006] This utility model adopts the following technical solution: a flatbed truck for transporting mine-use advanced hydraulic supports, comprising: The flatbed trailer body is horizontally set, and two fixing holes are opened from top to bottom on the body of the flatbed trailer body. The two fixing holes are located near the left side of the flatbed trailer body. Three hydraulic clamps are vertically installed, with their lower ends welded to the upper side of the flatbed vehicle body. The upper ends of the three hydraulic clamps extend upward and are installed along the right side of the flatbed vehicle body. The three hydraulic clamps are arranged in a straight line. The fixed plate is horizontally set on the underside of the flatbed truck body; Two rising levers are vertically set on the upper side of the fixed plate. Their lower ends are fixedly connected to the fixed plate, and their upper ends are used to extend upward through two fixing holes in the flatbed vehicle body. The limiting plate is U-shaped, with its opening facing the left edge of the flatbed vehicle body. Its opening is used to extend into the left edge of the flatbed vehicle body. Two grooves are opened on the upper half edge of the limiting plate. The two grooves are used to extend into the periphery of two corresponding rising rods, thereby causing the rising rods to be locked. The three hydraulic locking pins are positioned on the left side to lift the hydraulic support onto the flatbed truck and then rest against the right side of the hydraulic support; the two rising locking rods are used to pass through the fixing holes and lock onto the left side of the hydraulic support, thereby completely locking the hydraulic support.

[0007] The beneficial effects of this utility model are: This utility model can firmly fix the advanced hydraulic support above it, avoiding the hydraulic support from swaying left and right and back and forth. During underground transportation, it ensures the safety of equipment transportation, improves the installation progress of the face support, and improves the recovery progress of the face. This invention uses three hydraulic locking pins and two rising locking rods to completely lock the hydraulic support, and uses a limit plate to clamp the rising locking rods, making operation very simple.

[0013] The flatbed trailer body 10 is set horizontally, and two fixing holes are opened from top to bottom on the flatbed trailer body 10. The two fixing holes are located near the left side of the flatbed trailer body 10.

[0014] Three hydraulic clamps 11 are vertically arranged, with their lower ends welded to the upper side of the flatbed vehicle body 10. The upper ends of the three hydraulic clamps 11 extend upward and are arranged along the right side of the flatbed vehicle body 10. The three hydraulic clamps 11 are arranged in a straight line.

[0015] The fixing plate 12 is horizontally set on the lower side of the flatbed vehicle body 10.

[0016] Two lifting rods 13 are vertically arranged on the upper side of the fixed plate 12. The lower ends of the two lifting rods 13 are fixedly connected to the fixed plate 12, and the upper ends of the two lifting rods 13 are used to extend upward through the two fixing holes of the flatbed vehicle body 10.

[0017] The limiting plate 14 is U-shaped, with its opening facing the left side edge of the flatbed vehicle body 10. The opening of the limiting plate 14 is used to extend into the left side edge of the flatbed vehicle body 10. Two grooves are provided on the upper half edge of the limiting plate 14. The two grooves are used to extend into the periphery of the two corresponding rising rods 13, thereby causing the rising rods 13 to be locked.

[0018] The three hydraulic locking pins 11 are positioned on the left side to lift the hydraulic support onto the flatbed vehicle body 10 and then rest against the right side of the hydraulic support; the two rising locking rods 13 are used to pass through the fixing holes and lock onto the left side of the hydraulic support, thereby completely locking the hydraulic support.

[0019] The limiting plate 14 is composed of an upper horizontal section, a vertical section and a lower horizontal section that are fixedly connected in sequence. Two grooves are opened at the edge of the upper horizontal section; the vertical section has a limiting hole through it from left to right.

[0021] The two lifting rods 13 are composed of an enlarged column 16 and a connecting column 17 from top to bottom. The diameter of the enlarged column 16 is smaller than the diameter of the fixing hole, and the diameter of the connecting column 17 is smaller than the diameter of the enlarged column 16. The lower side of the enlarged column 16 is used for the groove to extend into, thereby locking the lifting rod 13. Example

[0022] During the installation of pre-supports in a certain mine, the pre-supports were placed directly on a flatbed truck and secured with steel wire ropes. During transportation, the vehicle swayed significantly, and the loading equipment tilted to the left and right, which could easily cause safety accidents such as the transport vehicle derailing.

[0023] Before using this invention, the advance support was directly placed on the flatbed truck and secured with steel wire ropes. During transportation, the vehicle swayed greatly, and the loading equipment tilted to the left and right, which could easily cause safety accidents such as the transport vehicle derailing. With this invention, the advance support is fixed to the flatbed truck body 10, and the advance hydraulic support is clamped between three hydraulic clamps 11 and two lifting clamps 13. Finally, it is secured a second time with steel wire ropes, which greatly solves the safety problem of the advance support tilting to the left and right during transportation.
