Description

Technical Field

[0001] The present invention relates to the field of lifting, and in particular to a container gantry crane. Background Art

[0002] Gantry cranes, also known as gantry cranes, are a variation of bridge cranes. They are primarily used for loading and unloading bulk cargo in outdoor cargo yards, material yards, and bulk cargo. Gantry cranes are widely used in port cargo yards due to their high site utilization, large operating range, wide adaptability, and strong versatility.

[0003] Its metal structure is like a door-shaped frame, with two supporting legs installed under the main beam, so it can run directly on the track on the ground. Both ends of the main beam can have outward cantilever beams.

[0004] Existing gantry cranes are generally composed of a traveling part and a lifting part. The traveling part of the existing gantry crane is basically completed by fixing a moving frame under the column, and rollers are provided in the moving frame to complete the movement of the lifting part. However, when encountering a small slope or small obstacle, the gantry crane as a whole is prone to tilt or shake. Summary of the Invention

[0005] Purpose of the invention: To provide a container gantry crane to solve the above-mentioned problems existing in the prior art.

[0006] Technical solution: A container gantry crane, comprising:

[0007] Columns, designed in multiple groups;

[0008] The lifting part is installed on the column; the side of the column is also provided with a ladder connected to the beam;

[0009] It also includes a traveling mechanism, which is installed under the column to enable the gantry crane to adjust its position and adapt to obstacles encountered during the gantry crane's travel;

[0010] The walking mechanism comprises:

[0011] Walking connecting frame, connected with the column;

[0012] The main bearing frame is hinged to the walking articulated frame;

[0013] The auxiliary bearing frame is hinged to one end of the main bearing frame, and the two ends are respectively hinged to the first bottom bearing frame;

[0014] The second bottom load-bearing frame is hinged to the other end of the main load-bearing frame;

[0015] The second bottom load-bearing frame is close to the inner side of the gantry crane;

[0016] The first bottom-layer supporting frame and the second bottom-layer supporting frame are both provided with driving rollers.

[0017] By articulating multiple load-bearing frames, when the traveling mechanism encounters an obstacle or a slope, it can adapt to the obstacle and the slope, thereby preventing the gantry crane from tilting when encountering an obstacle or a slope.

[0018] At the same time, the auxiliary bearing frame and the second bottom bearing frame are hinged under the main bearing frame, and the first bottom bearing frame is hinged under the auxiliary bearing frame, so that the walking connecting frame can adaptively tilt, so that the center of gravity of the entire gantry crane is close to the second bottom bearing frame. Since the second bottom bearing frame is close to the inside of the gantry crane, the entire gantry crane is more stable.

[0019] In a further embodiment, the first bottom-layer carrier and the second bottom-layer carrier are both provided with a travel motor for driving the driving roller to rotate;

[0020] The lifting part includes:

[0021] A crossbeam, mounted on the uprights, is I-shaped and has a tooth groove on the top inner wall;

[0022] The purpose of providing tooth grooves on the crossbeam is to make the driving force more stable and avoid slipping. When the driving wheel with smooth transmission is driven, when the motor rotates at a high speed instantaneously, the driving wheel is prone to slipping.

[0023] A sliding mechanism is provided above the crossbeam and adapted to the crossbeam, and reciprocates along the crossbeam;

[0024] The lifting spreader is fixedly connected to the sliding mechanism and is used to lift the container.

[0025] In a further embodiment, the sliding mechanism comprises:

[0026] Sliding moving unit, adapted to the crossbeam;

[0027] The sliding drive unit is installed on the sliding moving unit.

[0028] In a further embodiment, the sliding movement unit comprises:

[0029] A sliding movable frame and a sliding connecting frame fixedly connected to the sliding movable frame;

[0030] The side pulley is arranged on the side of the sliding frame and abuts against the crossbeam;

[0031] A top limiting pulley is provided at the bottom of the sliding frame and abuts against the crossbeam;

[0032] The bottom limiting pulley is arranged on the side of the sliding connecting frame, abuts against the crossbeam, and cooperates with the top limiting pulley to stabilize the entire sliding moving unit on the crossbeam.

[0033] In a further embodiment, the sliding drive unit comprises:

[0034] The sliding drive motor is fixedly connected to the sliding movable frame, and the output end of the motor is provided with a sliding drive shaft, on which a gear matching the tooth groove is sleeved;

[0035] A driving brake unit is fixedly connected to the sliding drive motor and is used to limit the rotation of the sliding drive shaft;

[0036] The end of the sliding drive shaft can also be used in conjunction with a reducer. The gear can be placed on the output end of the reducer to increase the torque of the driving force. The reduction ratio can be controlled according to the specific situation, and whether a reducer needs to be installed can be determined.

[0037] By designing the driving brake unit, the inertia generated by the sliding drive motor driving the sliding moving unit can be avoided;

[0038] When the sliding drive motor drives the sliding moving unit to move to the predetermined point, the sliding drive motor stops working. However, at this time, the sliding moving unit is affected by its own inertia and continues to slide, thereby affecting the landing point, causing the lifting point to shift and affecting the lifting;

[0039] By designing a driving brake unit, the continued rotation of the sliding drive shaft is restricted, thereby restricting the movement of the sliding movable unit, thereby preventing the sliding movable unit from continuing to move due to its own inertia.

[0040] In a further embodiment, the driving brake unit comprises:

[0041] A brake frame, fixedly connected to the sliding drive motor;

[0042] The brake cylinder is installed on the brake frame, and its output end is provided with a brake telescopic rod. The end of the brake telescopic rod is provided with an anti-slip pad for supporting the brake disc and limiting the rotation of the brake disc;

[0043] The brake disc is sleeved on the sliding drive shaft.

[0044] In a further embodiment, the lifting spreader comprises:

[0045] A lifting portion fixedly connected to the sliding connection frame;

[0046] The clamping portion is arranged below the lifting portion.

[0047] In a further embodiment, the lifting portion comprises:

[0048] A lifting frame, fixedly connected to the sliding connecting frame;

[0049] A lifting motor is mounted on the lifting frame and has an output shaft at its output end;

[0050] The lifting gear set is connected to the output shaft and is a reduction gear set used to increase the lifting torque of the lifting part;

[0051] A lifting drum is connected to the output end of the lifting gear set, and a lifting cable is wound around the lifting drum;

[0052] There are multiple sets of lifting and winding wheels, which are installed on both sides and the top of the lifting frame respectively, and are used to wind the lifting cable and form it into a predetermined shape.

[0053] In a further embodiment, the clamping portion comprises:

[0054] Spreader frame, located below the lifting frame;

[0055] The hoisting wheels are designed in multiple groups and are respectively installed on the top of the spreader frame and placed in a cross direction for winding the hoisting cable;

[0056] A clamp, fixedly connected to the spreader frame;

[0057] The positioning block is installed on one side of the fixture and is fixedly connected to the spreader frame;

[0058] The fixture comprises:

[0059] A clamp, fixedly connected to the spreader frame;

[0060] The driving component is connected to the clamping component so that the clamping component clamps the adapter component pre-installed on the container.

[0061] In a further embodiment, the clamping member includes a clamping frame fixedly connected to the hanger frame and mounted on the end of the fixed column, a balancing block provided on both sides of the clamping frame, and a clamping arm hingedly connected to both ends of the clamping frame; the clamping arm is adapted to the adapter;

[0062] A movable column is provided inside the fixed part, a waist hole is opened on the side of the fixed part, and a connecting rod is inserted into the movable column;

[0063] A rotating rod is inserted into the side of the fixed column, and a hinged frame is hinged on the rotating rod;

[0064] The connecting rod passes through the waist hole and is hinged to the hinge frame;

[0065] The movable column passes through the fixed part and is hinged to the clamp arm;

[0066] The driving member includes an extension cylinder hinged to the balancing block, and an extension telescopic rod arranged at the output end of the extension cylinder and hinged to the articulated frame.

[0067] The container lifting work is completed by clamping the adapter rod with a designed fixture, which is more stable than the traditional rotating shaft connection method;

[0068] The traditional connection method is to design a rotating shaft at the four corners of the spreader frame, with an extension section at the end of the rotating shaft, and a notch that matches the extension section is opened on the container, and then the rotating shaft is connected to the notch, and the rotating shaft is rotated so that the extension section of the rotating shaft is stuck in the container to complete the lifting and fixing work. However, during the rotation process, the rotation amplitude is difficult to control. At the same time, since the rotating shaft needs to fall into the notch, the lifting cable must be in a relaxed state at this time. Even when the rotating shaft is rotated into place, the position of the extension section of the rotating shaft will be offset during the process of lifting and straightening the lifting cable. Once the offset position overlaps with the notch, the container will not be stuck at this time, and a lifting accident will occur.

[0069] The present application uses a clamping method to clamp the adapter pre-installed on the container, thereby avoiding the position change that occurs when the lifting cable is tightened from the anti-loose state. After the adapter is clamped, the clamp is fixed and the technical lifting cable state changes, but the clamp state remains in the clamped state, avoiding the risk of loosening.

[0070] Beneficial effects: The present invention discloses a container gantry crane. The present invention designs a traveling mechanism and mutually hinges multiple load-bearing frames. When the traveling mechanism encounters an obstacle or a slope, the mechanism adapts to the obstacle and the slope, thereby preventing the gantry crane from tilting when encountering an obstacle or a slope.

[0095] The present application relates to a container gantry crane, which is explained in detail below through specific implementation methods.

[0096] A container gantry crane, comprising:

[0097] Column 1, designed in multiple groups;

[0098] The lifting part is installed on the column 1; the side of the column 1 is also provided with a ladder 6, which is connected to the beam 3;

[0099] It also includes a traveling mechanism 2, which is installed under the column 1 and enables the gantry crane to adjust its position and adapt to obstacles encountered during the gantry crane's travel;

[0100] The walking mechanism 2 includes:

[0101] The walking connecting frame 21 is connected to the column 1;

[0102] The main bearing frame 22 is hinged to the traveling articulated frame 5231F;

[0103] The auxiliary carrier frame 23 is hinged to one end of the main carrier frame 22, and the first bottom carrier frame 25 is hinged to both ends;

[0104] The second bottom supporting frame 24 is hinged to the other end of the main supporting frame 22;

[0105] The second bottom load-bearing frame 24 is close to the inner side of the gantry crane;

[0106] Both the first bottom-level supporting frame 25 and the second bottom-level supporting frame 24 are provided with driving rollers 27 .

[0107] By mutually articulating a plurality of carriers, when the traveling mechanism 2 encounters an obstacle or a slope, it adapts to the obstacle and the slope, thereby preventing the gantry crane from tilting when encountering an obstacle or a slope.

[0108] At the same time, the auxiliary bearing frame 23 and the second bottom bearing frame 24 are hinged below the main bearing frame 22, and the first bottom bearing frame 25 is hinged below the auxiliary bearing frame 23, so that the walking connecting frame 21 can be adaptively tilted, so that the center of gravity of the entire gantry crane is close to the second bottom bearing frame 24. Since the second bottom bearing frame 24 is close to the inside of the gantry crane, the entire gantry crane is made more stable.

[0109] The first bottom-layer carrier 25 and the second bottom-layer carrier 24 are both provided with a travel motor for driving the driving roller 27 to rotate;

[0110] The lifting part includes:

[0111] The crossbeam 3 is mounted on the column 1 and is in an I-shape, with a tooth groove 31 on the top inner wall;

[0112] The sliding mechanism 4 is arranged above the crossbeam 3 and is adapted to the crossbeam 3 and reciprocates along the crossbeam 3;

[0113] The lifting device 5 is fixedly connected to the sliding mechanism 4 and is used for lifting the container.

[0114] The sliding mechanism 4 includes:

[0115] Sliding moving unit 41, adapted to the crossbeam 3;

[0116] The sliding driving unit 42 is installed on the sliding moving unit 41 .

[0117] The sliding movement unit 41 includes:

[0118] A sliding frame 411 and a sliding connecting frame 412 fixedly connected to the sliding frame 411;

[0119] The side pulley 413 is provided on the side of the sliding frame 411 and abuts against the crossbeam 3;

[0120] The top limiting pulley 415 is provided at the bottom of the sliding frame 411 and abuts against the crossbeam 3;

[0121] The bottom limiting pulley 414 is provided on the side of the sliding connection frame 412 , abuts against the crossbeam 3 , and cooperates with the top limiting pulley to stabilize the entire sliding moving unit 41 on the crossbeam 3 .

[0122] The sliding drive unit 42 includes:

[0123] The sliding drive motor 421 is fixedly connected to the sliding movable frame 411, and the output end thereof is provided with a sliding drive shaft 422, and the sliding drive shaft 422 is sleeved with a gear adapted to the tooth groove 31;

[0124] The driving brake unit 423 is fixedly connected to the sliding driving motor 421 and is used to limit the rotation of the sliding driving shaft 422;

[0125] The end of the sliding drive shaft 422 can also be used in conjunction with a reducer. The gear can be put on the output end of the reducer to increase the torque of the driving force. The reduction ratio can be controlled according to the specific situation, and whether a reducer needs to be installed can be determined.

[0126] By designing the driving brake unit 423, the inertia generated by the sliding driving motor 421 driving the sliding moving unit 41 is avoided;

[0127] When the sliding drive motor 421 drives the sliding moving unit 41 to move to the predetermined point, the sliding drive motor 421 stops working.

[0128] At this time, the sliding moving unit 41 is affected by its own inertia and continues to slide, thereby affecting the landing point, causing the lifting point to shift, affecting the lifting;

[0129] By designing the driving brake unit 423 , the continued rotation of the sliding driving shaft 422 is restricted, thereby restricting the movement of the sliding moving unit 41 , thereby preventing the sliding moving unit 41 from continuing to move due to its own inertia.

[0130] The driving brake unit 423 includes:

[0131] The brake frame 423A is fixedly connected to the sliding drive motor 421;

[0132] Brake cylinder 423B is mounted on brake frame 423A. A brake telescopic rod 423C is provided at its output end. An anti-slip pad is provided at the end of brake telescopic rod 423C to abut against brake disc 423D and limit its rotation.

[0133] When the sliding frame 411 moves to the appropriate position, the brake cylinder 423B drives the brake telescopic rod 423C, which in turn drives the anti-slip gasket to press against the brake disc 423D, limiting the rotation of the brake disc 423D, thereby limiting the rotation of the sliding drive shaft 422, and thus limiting the continued movement of the entire sliding frame 411. As the sliding frame 411 continues to move, it will drive the gear to continue to rotate, thereby driving the sliding drive shaft 422 to continue to rotate. At this time, the rotation of the sliding drive shaft 422 is limited, thereby completing the work of limiting the movement of the sliding frame 411.

[0134] The brake disc 423D is sleeved on the sliding drive shaft 422 .

[0135] The lifting device 5 comprises:

[0136] The lifting part is fixedly connected to the sliding connecting frame 412;

[0137] The clamping portion is arranged below the lifting portion.

[0138] In a further embodiment, the lifting portion comprises:

[0139] The lifting frame 511 is fixedly connected to the sliding connecting frame 412;

[0140] The lifting motor 512 is mounted on the lifting frame 511 and has an output shaft at its output end;

[0141] The lifting gear set 513 is connected to the output shaft and is a reduction gear set used to increase the lifting torque of the lifting part;

[0142] The lifting drum 514 is connected to the output end of the lifting gear set 513, and a suspension cable 516 is wound around the lifting drum 514;

[0143] The lifting winding wheels 515 are designed in multiple sets and are respectively installed on both sides and the top of the lifting frame 511 to wind the suspension cable 516 and form it into a predetermined shape.

[0144] The clamping portion comprises:

[0145] The spreader frame 521 is located below the lifting frame 511;

[0146] The hoisting wheels 522 are designed in multiple groups and are respectively installed on the top of the hoisting frame 521 and placed in a cross direction for winding the hoisting cable 516;

[0147] The clamp 523 is fixedly connected to the hanger frame 521;

[0148] The positioning block 524 is installed on one side of the clamp 523 and is fixedly connected to the hanger frame 521;

[0149] The fixture 523 includes:

[0150] The clamp 5231 is fixedly connected to the hanger frame 521;

[0151] The driving member 5232 is connected to the clamping member 5231 so that the clamping member 5231 clamps the adapter 7 pre-installed on the container.

[0152] The positioning block 524 is designed to abut against the container to complete the positioning, so that the clamping piece 5231 clamps the adapter 7.

[0153] In a further embodiment, the clamping member 5231 includes a clamping frame 5231C fixedly connected to the hanger frame 521 and mounted on the end of the fixed column 5231B, a balancing block 5231D provided on both sides of the clamping frame 5231C, and a clamping arm 5231E hingedly connected to both ends of the clamping frame 5231C; the clamping arm 5231E is adapted to the adapter 7;

[0154] A movable column 5231A is provided inside the fixed part, a waist hole is opened on the side of the fixed part, and a connecting rod 5231H is inserted into the movable column 5231A;

[0155] The side of the fixed column 5231B is plugged with a rotating rod 5231G, and the rotating rod 5231G is hinged with a hinge frame 5231F;

[0156] The connecting rod 5231H passes through the waist hole and is hinged to the hinge frame 5231F;

[0157] The movable column 5231A passes through the fixed portion and is hinged to the clamping arm 5231E;

[0158] The driving member 5232 includes an extension cylinder hinged to the balancing block 5231D, and an extension telescopic rod arranged at the output end of the extension cylinder and hinged to the articulated frame 5231F.

[0159] The container lifting operation is completed by designing a clamp 523 to clamp the adapter rod, which is more stable than the traditional rotating shaft connection method.

[0160] The traditional connection method is to design a rotating shaft at the four corners of the spreader frame 521, with an extension section at the end of the rotating shaft, and a notch that matches the extension section is opened on the container, and then the rotating shaft is connected to the notch, and the rotating shaft is rotated so that the extension section of the rotating shaft is stuck in the container to complete the lifting and fixing work. However, during the rotation process, the rotation amplitude is difficult to control. At the same time, since the rotating shaft needs to fall into the notch, the lifting cable 516 must be in a loose-proof state at this time. Even when the rotating shaft is rotated into place, the position of the extension section of the rotating shaft will be offset during the process of straightening the lifting cable 516. Once the offset position overlaps with the notch, the main container will not be able to be stuck at this time, and a lifting accident will occur.

[0161] The present application clamps the adapter 7 pre-installed on the container by means of clamping, thereby avoiding the position change that occurs when the lifting cable 516 is tightened from the anti-loose state. After the adapter 7 is clamped, the clamp 523 is fixed, the state of the technical lifting cable 516 changes, and the state of the clamp 523 remains in the clamped state, avoiding the risk of loosening.

[0162] Working principle description: When the gantry crane needs to move, the travel motor drives the driving roller 27 to rotate, thereby completing the movement of the gantry crane;

[0163] When the gantry crane needs to lift a container, it is accomplished through the sliding mechanism 4 and the lifting spreader 5;

[0164] The sliding drive motor 421 drives the sliding drive shaft 422 to rotate, thereby driving the gear to rotate on the tooth groove 31, and then driving the sliding movable frame 411 to move along the crossbeam 3. During the movement, the side pulleys 413, the bottom limiting pulley 414 and the top limiting pulley 415 stabilize the sliding movable frame 411;

[0165] When the sliding frame 411 moves to the appropriate position, the brake cylinder 423B drives the brake telescopic rod 423C, which in turn drives the anti-slip pad to press against the brake disc 423D, restricting the rotation of the brake disc 423D, thereby restricting the rotation of the sliding drive shaft 422, and thus restricting the entire sliding frame 411 from continuing to move;

[0166] The lifting motor 512 then drives the output shaft to rotate, driving the lifting gear set 513 to rotate, and then driving the lifting drum 514 to prevent the loosening of the lifting cable 516, so that the spreader frame 521 sinks to the top of the container and engages with the four corners of the container through the positioning blocks 524 to complete the positioning. The extension cylinder drives the extension telescopic rod to extend and retract, thereby driving the articulated frame 5231F to swing, and then driving the connecting rod 5231H to rise in the waist hole, and then driving the movable column 5231A to rise in the fixed column 5231B, and then driving the clamping arm 5231E to clamp the adapter 7, thereby completing the clamping work of the container;

[0167] And then complete the entire lifting work.

However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and these equivalent transformations all fall within the scope of protection of the present invention.
