[0046] Embodiment 1, as Figures 1 to 3 As shown, the hydraulic transmission device for loading and unloading a bare glass container provided by the present invention includes a base 1, an electric control box 9 installed on the base 1, a retractable guide rail 3, a first hydraulic cylinder 51, and a transfer trolley. The transfer trolley is arranged in the middle of the base 1, the electric control box 9 is arranged on the rear side of the transfer trolley 2, the retractable guide rail 3 is arranged below the transfer trolley 2, the transfer trolley 2 can be slidably arranged on the retractable guide rail 3 along the retractable guide rail 3, and the first hydraulic cylinder 51 is installed on the base to drive the transfer trolley 2 to move forward and backward.

[0047] Retractable guide rails are currently widely used, and their structure and principle are the same as those in the prior art, which will not be described in detail here.

[0048] The piston rod of the first hydraulic cylinder 51 is connected to the base 1, and the cylinder body of the first hydraulic cylinder 51 is connected to the body of the transfer vehicle 2. When the piston rod of the first hydraulic cylinder 51 is extended, the transfer vehicle 2 is driven forward along the guide rail 3, and when the piston rod of the first hydraulic cylinder 51 is retracted, the transfer vehicle 2 is driven backward along the guide rail 3. A fixing seat 101 is provided on the base 1, and the piston rod of the first hydraulic cylinder 51 is hinged to the fixing seat 101, so that the replacement, disassembly and maintenance of the device are more convenient.

[0049] The transfer trolley 2 includes a body 21, a movable seat 22, two front forks 71, four sleepers and two rear support frames 72. A second hydraulic cylinder 52 for driving the movable seat 22 to rise and fall is arranged on the top of the body 21 of the transfer trolley 2, the two front forks 71 are symmetrically arranged on both sides of the moving seat 22, the two rear support frames 72 are symmetrically arranged on both sides of the moving seat 22, the two front forks 71 and the two rear support frames 72 are arranged at intervals in front and rear along the moving seat 22, the front fork 71 is L-shaped, and includes a vertical rod 711 and a horizontal rod 712, the upper end of the rear support frame 72 is fixedly connected to the movable seat 22, and the lower end of the rear support frame 72 is provided with a horizontal bearing platform 720. Two sleepers 8 are provided on both sides of the moving seat 22 in the forward direction. The two sleepers 8 are respectively arranged on the inner sides of the horizontal rod 712 and the bearing platform 720 facing each other. The side surfaces of the sleepers 8 are adsorbed on the inner sides of the horizontal rod 712 and the bearing platform 720 by magnets. When the moving seat 22 is lowered to the lowest point, the height of the sleepers 8 is higher than the horizontal rod 712 and the bearing platform 720. The horizontal rod 712 and the bearing platform 720 are used to support the bare glass, and the bare glass can lean on the moving seat 22.

[0050] In addition, in other feasible implementations, a front fork 71 and a rear support frame 72 are provided on one side of the movable seat 22 .

[0051] The electric control box 9 is used to control the extension and retraction of the piston rods of the first hydraulic cylinder 51 , the second hydraulic cylinder 52 , and the third hydraulic cylinder 53 , and to control the rotating mechanism to drive the front fork 71 to rotate.

[0052] The cylinder body of the second hydraulic cylinder 52 is fixed on the top of the body 22 of the transfer vehicle, and the piston rod of the second hydraulic cylinder 52 is fixedly connected to the movable seat 22 .

[0053] The transfer trolley 2 further comprises an A-frame 4, which is fixed to the top of the movable seat 22. When the bare glass is placed on the sleepers 8 in packages, the upper ends of the bare glass are leaning against the left and right sides of the A-frame 4, and the lower ends of the bare glass are supported by the sleepers 8.

[0054] Glass is easily damaged during the transportation of container cargoes. The A-frame is provided with a third hydraulic cylinder 53 for pushing the bare glass to both sides. During loading and unloading of the cabinet, it is safer to press the upper end of the bare glass against the A-frame. When loading the cabinet, the third hydraulic cylinder 53 pushes the bare glass to both sides, that is, pushes the inclined bare glass upright so that the bare glass is perpendicular to the horizontal direction. During container transportation, the glass is less damaged when it is transported upright. When unloading the cabinet, after the transfer trolley 2 and the A-frame 4 arrive at the position, the reinforced glass in the cabinet is kept still on one side, and the reinforcing straps on the other side are loosened, and the glass will fall to the A-frame 4, or it can be gently pried with a wooden board, and the same method is used on the other side.

[0055] Soft buffer materials are provided on the surfaces of both sides of the A-frame 4 for contacting the bare coated glass to reduce the damage of the contact surface between the upper end of the glass and the A-frame 4.

[0056] The bottom of the transfer trolley 2 is provided with two rows of limiting wheels 211, and the retractable guide rails 3 are clamped between the two rows of limiting wheels 211 to guide the transfer trolley 2 to slide. The bottom of the transfer trolley 2 is also provided with two rows of load-bearing wheels 212, which are arranged on the opposite outer sides of the two rows of limiting wheels 211. The two rows of load-bearing wheels 212 and the two rows of limiting wheels 211 share the load-bearing together, thereby increasing the stability of the transfer trolley 2 and preventing it from tipping over.

[0057] The side of the sleeper 8 is provided with three grooves, and magnets are embedded in the grooves. The sleeper 8 is adsorbed on the side of the horizontal rod 712 and the bearing platform 720 through the magnets. When the horizontal rod 712 and the bearing platform 720 lift the glass and move, the sleeper moves with the horizontal rod 712 and the bearing platform 720.

[0058] The rotating mechanism includes an upper fixed plate 2201, a lower fixed plate 2202 and a rotating shaft 2203. The upper fixed plate 2201 and the lower fixed plate 2202 are fixedly connected to the movable seat 22. The upper and lower ends of the rotating shaft 2203 are rotatably mounted on the upper fixed plate 2201 and the lower fixed plate 2202 through bearings. The rotating shaft 2203 is fixedly connected to the upper end of the vertical rod 711 through a connecting plate arranged on the inner side of the vertical rod 711 of the front fork 71. The middle part of the rotating shaft 2203 is sleeved with a gear 2204, and the gear is provided with torque by a driving device. The driving device drives the gear to rotate and then drives the rotating shaft 2203 and the front fork 71 to rotate. The driving device includes a motor. The rotating mechanism can also adopt other suitable structures as long as it can drive the front fork 71 to rotate. In addition, in other feasible embodiments, the horizontal rod 712 of the front fork 71 is assembled on the load-bearing fixed sleeve, and the horizontal rod 712 is driven by the cylinder piston to extend and retract perpendicular to the forward and backward movement direction of the movable seat 22, so that when the movable seat 22 moves forward along the telescopic guide rail 3, the bearing platform 720 is wedged into the bottom of the glass, and then the cylinder piston is driven to drive the horizontal rod 712 to extend and insert into the bottom of the glass. During the process of the second hydraulic cylinder driving the movable seat 22 to rise and fall, the load-bearing fixed sleeve can increase the weight carried by the horizontal rod 712. After the glass is sent into the container and placed on the container floor, the horizontal rod 712 is retracted by the cylinder piston, and then the movable seat 22 is driven by the first hydraulic cylinder to move back along the telescopic guide rail 3, so that the bearing platform 720 is also separated from the bottom of the glass. Preferably, the embodiment of the present invention uses a rotating mechanism to assemble the front fork 71 and the movable seat 22, and the following operation process is also illustrated by assembling the front fork 71 and the movable seat 22 by the rotating mechanism.

[0059] A plurality of cross beams 100 are arranged at intervals at the bottom of the base 1 to facilitate the movement of the entire device by a forklift or a truck.

[0060] like Figures 4-5 As shown, the working process of the hydraulic transmission device for loading and unloading a bare glass container of the present invention is as follows:

[0061] (1) Back the truck with container 02 to platform 01, open the container door, and use a forklift or crane to place the hydraulic transmission device on platform 01 and dock it with the door of container 02, ready for loading;

[0062] (2) Place a sleeper 8 on the inner side of each front fork and rear support frame, and place the bare glass 6 in packs on the sleepers 8. The lower end of the glass 6 is supported by the sleepers 8, and the upper end of the glass 6 is pressed against the A-frame 4 and reinforced with straps;

[0063] (3) The retractable guide rail is electrically extended into the container (cargo container) 02;

[0064] (4) Operate the electric control box 9 or the wireless remote control button at the rear of the transfer vehicle, the second hydraulic cylinder 52 under the A frame drives the movable seat 22 to rise, and the movable seat 22 drives the front fork 71 and the rear support frame 72 to lift the entire frame of glass by 30 mm, so that the load at the lower end of the glass is completely transferred to the front fork 71 and the rear support frame 72;

[0065] (5) The first hydraulic cylinder 51 pushes the transfer trolley 2 forward along the retractable guide rail 3. The wheels (limiting wheels and load-bearing wheels) of the transfer trolley 2 move along the retractable guide rail 3 on the base 1 and the container 02 in turn, and the entire frame of glass is delivered to the middle position in the container. When the transfer trolley 2 moves, the sleepers 8 are adsorbed on the front fork 71 and the rear support frame 72 and move forward with it;

[0066] (6) Operate the electric control box 9 to control the second hydraulic cylinder 52 to lower the entire glass frame to the bottom of the cabinet, lower the front fork 71 and the rear support frame 72, and the weight at the lower end of the glass falls on the sleeper 8;

[0067] (7) Operate the electric control box 9 to control the third hydraulic cylinder 73 to push the glass toward both sides of the container, tie the steel belt or tie strap, and then retract the hydraulic rod of the third hydraulic cylinder 53;

[0068] (8) The front forks 71 on both sides of the front end of the cabinet are electrically rotated 90 degrees, and the front forks 71 are retracted so that the front forks 71 and the transfer trolley 2 can pass through the gap between the glass on both sides;

[0069] (9) Press the remote control button to move the transfer trolley 2 out of the container. The front fork 71 and the transfer trolley 2 pass through the gap between the two side glasses. The sleepers 8 are pressed by the glass and remain in the container. The guide rails 3 are retracted and other reinforcements are carried out inside the container. The loading of the container is completed.

[0070] The above is the process of loading the container. The unloading process can be completed by following the reverse operation.

[0071] The beneficial effects of the present invention are as follows: the present invention delivers a whole frame of glass into the container through the transfer trolley 2, and rotates the front fork 71 90 degrees inward and forward through the rotating mechanism, and the front fork 71 retracts, so that the front fork and the transfer trolley 2 can pass through the gap between the glasses on both sides; the first hydraulic cylinder 51 is used to push the transfer trolley 2 to move forward and backward, and the second hydraulic cylinder 52 is used to lift the movable seat 22. The hydraulic cylinder can provide a large torque to lift the whole frame of glass. The transfer trolley 2 can transfer glass weighing up to 27 tons at a time, and the loading and unloading time of the container is short and the efficiency is high, which reduces the safety risk of loading and unloading of bare glass; the number of operators is reduced, and only 1 to 2 people are needed to complete the loading and unloading operations of the container; hydraulic transmission is used, which is energy-saving and environmentally friendly, and 10-ton or larger fuel forklifts are no longer used for loading and unloading; an A-frame 4 is set, and a third hydraulic cylinder 53 for pushing the bare glass to both sides is provided on the A-frame 4. During the container transportation, the glass is transported upright with less damage.

[0072] A bare glass loading and unloading container system includes the above-mentioned bare glass loading and unloading container hydraulic transmission device, and also includes an intermediate reinforcement mechanism and a limit mechanism arranged in the container. Figure 6 As shown, the intermediate reinforcement mechanism includes at least one pair of columns 63 arranged between two bare glass frames 6. One or more pairs of columns 63 can be arranged between two bare glass frames 6 as needed. Two distance adjustment mechanisms are arranged at intervals along the upper and lower sides of the inner sides of the paired columns 63. The distance adjustment mechanism includes a first lead screw 65, a second lead screw 66 and a nut 64. The first lead screw 65 is provided with a left-handed external thread, the second lead screw 66 is provided with a right-handed external thread, and the nut 64 is provided with an internal thread matching the left-handed external thread of the first lead screw 65 and the right-handed external thread of the second lead screw 66. The outer ends of the first lead screw 65 and the second lead screw 66 are embedded in the inner sides of the columns 63, and the inner ends of the first lead screw 65 and the second lead screw 66 are threadedly connected with the nut 64. By turning the middle nut 64, the first lead screw 65 and the second lead screw 66 can be retracted inward or extended outward to adjust the distance between the two paired columns 63. The intermediate reinforcement mechanism of the present invention has simple installation and disassembly procedures and can be assembled and disassembled multiple times and reused.

[0073] like Figure 5 , Figure 7As shown, after the bare glass 6 is sent into the container 02, there is about 1.2 meters of space at both ends of the bare glass 6. In order to prevent the bare glass in the cabinet from shifting forward and backward, the present invention is also provided with a limiting mechanism. The limiting mechanism is arranged at the front and rear ends of the bare glass 6 to prevent the bare glass from shifting forward and backward. The limiting mechanism includes a limiting plate 61 and a locking plate 62. The cross section of the limiting plate 61 is L-shaped. The limiting plate 61 includes a vertical plate 611 and a horizontal plate 612. The vertical plate 611 is pressed against the front end or rear end of the bare glass 6. The contact surface between the vertical plate 611 and the bare glass is also provided with a soft buffer material. The locking plate 62 is pressed on the horizontal plate 612 on one side and on the bottom wall of the container 02 on the other side. The locking plate 62 is fixedly connected to the bottom plate of the container by an iron nail. The limiting plate 61 of the present invention can be reused, reducing material waste and being easy to disassemble and assemble.

[0074] The beneficial effects of the bare glass loading and unloading container system are: improved loading and unloading efficiency, reduced number of personnel, improved personnel safety, reduced glass breakage during loading and unloading, and energy saving and environmental protection; the installation and disassembly process of the glass reinforcement structure in the container is simple, and it can be disassembled and re-used many times, reducing material waste.
