Description

Technical Field

[0001] The present invention belongs to the technical field of mechanical manufacturing production process equipment, and in particular relates to a sliding drive mechanism for a gantry crane. Background Art

[0002] In the field of welding, gantry crane is an important lifting equipment, and the performance of its sliding drive mechanism directly affects the quality and efficiency of welding operations.

[0003] Chinese patent application number 2012104571192 discloses a gantry sliding drive mechanism, which is applied to a movable gantry structure (1). The gantry structure (1) includes two gantry columns (2); two gantry sliding drive mechanisms (3) are respectively installed on the surface of a workbench, so that the two gantry columns (2) move horizontally in the same direction; a synchronization mechanical device (4) is provided between the two gantry sliding drive mechanisms (3) to connect the two gantry sliding drive mechanisms (3); the gantry sliding drive mechanism (3) is a cylinder drive mechanism, and the same-direction cylinders of the two cylinder drive mechanisms are connected to the same air circuit. By adopting the above technical solution, the sliding motion of the columns on both sides of the gantry structure is kept synchronous and consistent. Therefore, during use, the gantry as a whole does not twist or deform, and mechanical failures such as device jamming will not occur, and the production process will not be adversely affected.

[0022] Example 1: like Figure 1-10 Specifically, the present invention provides a gantry crane sliding drive mechanism, including a gantry structure 100, which includes two gantry columns, namely a first gantry column 101 and a second gantry column 102, and a gantry beam 103, wherein the first gantry column 101 and the second gantry column 102 are arranged in parallel, and the gantry beam 103 is slidably arranged on top of the two gantry columns for installing and connecting welding equipment 700; It also includes a sliding drive mechanism for driving the gantry beam 103 to move, and the sliding drive mechanism includes two groups of slide rail assemblies, namely the first slide rail assembly 201 and the second slide rail assembly 202, and a first screw module 300, wherein the first slide rail assembly 201 is connected to the side of the first gantry column 101 close to the second gantry column 102, and is connected to the gantry beam 103 through the straight tripod 104, the second slide rail assembly 202 is arranged at the top of the second gantry column 102, and is connected to the gantry beam 103, and the first screw module 300 is connected to the top of the first gantry column 101 and is connected to the gantry beam 103.

[0023] The gantry structure adopts two parallel gantry columns, the first gantry column 101 and the second gantry column 102, in combination with the gantry beam 103 on the top. The column is L-shaped, with the longer side connected to the gantry beam and the shorter side connected to the base plate 800. This structure is similar to the stable frame in a building, which provides a solid support foundation for the entire gantry crane, effectively disperses the stress during operation, and reduces the shaking and deformation of the gantry structure during the lifting and welding process. Two sets of slide rail assemblies are set. The first slide rail assembly 201 is installed on the side of the first gantry column and is connected to the gantry beam through a straight tripod; the second slide rail assembly 202 is installed on the top of the second gantry column and is directly connected to the gantry beam. The cooperation of the slide rail and the slider can accurately guide the sliding movement of the gantry beam, limit its offset and swing during movement, ensure that the gantry beam maintains a stable posture during movement, and thereby ensure the stable operation of the welding equipment installed thereon. The slide rail assembly includes a slide rail and a slider slidably connected to the slide rail. The slide rails in the first slide rail assembly 201 and the second slide rail assembly 202 are arranged along the length direction of the first gantry column 101 and the second gantry column 102 respectively.

[0024] The gantry column is L-shaped, with a longer side facing upward and connected to the gantry beam 103 , and a shorter side connected to the base plate 800 .

[0025] A second screw module 400 is arranged along the length direction of the gantry beam 103 . The second screw module 400 is vertically connected to a third screw module 500 . The third screw module 500 is connected to a fine-tuning assembly 600 . The welding equipment 700 is connected to the fine-tuning assembly 600 .

[0026] The first screw module 300, the second screw module 400 and the third screw module 500 are all motor-driven screw modules, wherein the third screw module 500 also includes a first connecting plate 501 fixedly connected to the screw nut seat in the second screw module 400, a first screw module body 502 and a base 503, the screw nut seat in the first screw module body 502 is slidably set in the slide groove of the base 503, and the base 503 is fixedly connected to the first connecting plate 501.

[0027] The motor-driven screw modules (first screw module 300, second screw module 400, and third screw module 500) are used as the power source. The motor outputs stable torque, and the screw module converts the rotational motion into precise linear motion. Compared with traditional cylinder drive, it is less affected by external factors and can provide stable and precise power for the movement of the gantry beam and the adjustment of the welding equipment, avoiding equipment shaking caused by unstable power. It also includes a third slide rail assembly 203 , the slide rail of the third slide rail assembly 203 is fixedly connected to the bottom of the gantry beam 103 , and the slider of the third slide rail assembly 203 is fixedly connected to the first connecting plate 501 .

[0028] The third slide rail assembly 203 is installed at the bottom of the gantry beam, and its slider is connected to the first connecting plate 501. When the welding equipment is adjusted horizontally, it provides additional support and guidance for the welding equipment, further enhancing the stability of the welding equipment during the adjustment process and reducing shaking and deviation. The fine-tuning assembly 600 includes a second connecting plate 601 fixedly connected to the screw nut seat in the first screw module body 502, two fourth slide rail assemblies 204 arranged on the left and right sides of the first screw module body 502, the second screw module body 602 fixedly connected to the second connecting plate 601, and a mounting base plate 603 fixedly connected to the screw nut seat of the second screw module body 602. The mounting base plate 603 is fixedly connected to the mounting base 604 for mounting the welding equipment 700. The mounting base plate 603 and the second connecting plate 601 are provided with a fifth slide rail assembly 205. The slide rail of the fifth slide rail assembly 205 is fixedly connected to the second connecting plate 601, and the slider of the fifth slide rail assembly 205 is fixedly connected to the mounting base plate 603.

[0029] The fine-tuning assembly 600 is internally provided with a fourth rail assembly 204 and a fifth rail assembly 205. The fourth rail assembly 204 provides guidance and stability during horizontal adjustments of the fine-tuning assembly. The fifth rail assembly 205, located between the mounting base plate 603 and the second connecting plate 601, ensures the stability of the welding equipment during fine position adjustments, improving the precision and stability of fine-tuning.

[0030] A mounting slot 801 is defined on the base plate 800, within which a workbench 900 is mounted. The workbench 900 comprises a rotatable turntable 901 and a plurality of roller assemblies 904 arranged in an annular array on the base plate 800. The bottom of the turntable 901 contacts the roller assemblies 904, and a clamping fixture 902 for clamping objects is provided on the surface of the turntable 901. A power assembly 905 for driving the turntable 901 is provided below the workbench 900. The power assembly 905 comprises a drive motor 9051 and a reducer 9054, wherein the output shaft of the reducer 9054 is fixedly connected to the turntable 901, and the drive motor 9051 is in transmission connection with the reducer 9054 via a pulley structure 9052.

[0031] The workbench 900 utilizes a turntable 901 coupled with multiple roller assemblies 904 arranged in a circular array. Rollers 9042 of the roller assembly 904 are mounted on the base plate 800 via roller mounts 9041. The roller assembly evenly supports the turntable, distributing the weight of the workpiece on it and reducing wobbling caused by uneven center of gravity. Simultaneously, a drive motor 9051 drives the turntable via a pulley structure 9052 and a reducer 9054. The reducer delivers a steady torque, ensuring uniform rotation of the turntable and ensuring stability during rotation of the welded workpiece placed on the workbench.

[0032] Working principle: The first screw module 300 serves as a power source. When the motor starts, the screw module converts the motor's rotational motion into linear motion. Since the first screw module 300 is connected to the top of the first gantry column 101 and is connected to the gantry beam 103, the thrust or pull it generates drives the gantry beam 103 to move. During the movement, the first slide rail assembly 201 and the second slide rail assembly 202 play a key guiding role. The slider of the first slide rail assembly 201 is fixed to the straight tripod 104, which is in turn connected to the gantry beam 103. The slider of the second slide rail assembly 202 is directly connected to the gantry beam 103. The two sets of slide rails are arranged along the length direction of the column, which limits the movement trajectory of the gantry beam 103 so that it can only slide smoothly along the direction of the slide rail, thereby realizing the precise movement of the gantry beam on the top of the two gantry columns and providing a lateral position adjustment function for the welding equipment. On the gantry beam 103, the second screw module 400 is arranged along its length. When the motor of the second screw module 400 is started, the screw rotates and drives the nut seat to move, thereby causing the third screw module 500 and the welding equipment connected thereto to move in the length direction of the gantry beam, thereby achieving horizontal fine-tuning of the welding equipment. The third screw module 500 is arranged in the vertical direction. When its motor is running, the screw drives the nut seat to slide up and down in the slide groove of the base 503, thereby achieving height adjustment of the welding equipment. The fine-tuning component 600 further enhances the precision of the adjustment. The second screw module body 602 is installed on the second connecting plate 601. When the screw module is working, the mounting base 603 and the welding equipment 700 installed thereon will move slightly in the horizontal direction, meeting the precise requirements of the welding equipment position for high-precision welding operations. In addition, the fourth slide rail assembly 204 and the fifth slide rail assembly 205 provide guidance and stabilization at different parts of the fine-tuning assembly, respectively, to ensure the smoothness of the adjustment process. The power assembly 905 below the workbench 900 is the core component that realizes the rotation of the workbench. After the drive motor 9051 is started, it transmits power to the reducer 9054 via the pulley structure 9052. The reducer 9054 functions to reduce speed and increase torque. Its output shaft is fixedly connected to the turntable 901, transmitting the reduced torque to the turntable 901, enabling the turntable 901 to rotate smoothly supported by multiple roller assemblies 904. The clamping fixture 902 on the surface of the turntable 901 is used to secure the welding workpiece. As the turntable rotates, the workpiece also rotates, facilitating welding of different parts of the workpiece and improving the comprehensiveness and efficiency of the welding operation.
