Description

Technical Field

[0001] The utility model relates to the technical field of welding, in particular to an intelligent device for welding crane rail joints. Background Technique

[0002] During the use of a crane, the laying and maintenance of rails are essential links. Especially at the rail joints, due to long-term friction and vibration, problems such as unevenness and rust often occur, and welding repair is required.

[0003] Most of the traditional rail joint welding processes rely on manual operation, which has problems such as complex operation, low efficiency, and difficult quality assurance. Usually, the heavy crane rail joint welding equipment does not have the function of grinding the rails. It needs to be ground separately before docking, increasing manual operation and resulting in low welding efficiency. Therefore, we propose an intelligent device for welding crane rail joints. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problems in the prior art that most of the joint welding processes rely on manual operation, with complex operation, low efficiency, and the equipment does not have the grinding function, and to propose an intelligent device for welding crane rail joints.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] An intelligent device for welding crane rail joints, including a support base. The top inner wall of the support base is fixedly connected with a fixed block. Two electric push rods for cooperating with grinding are symmetrically and fixedly connected to the top inner wall of the support base. The top inner wall of the support base is fixedly connected with a guide rail, and a slider is slidably connected through the guide rail. The device further includes:

[0007] Two clamping mechanisms are respectively arranged at the bottoms of the fixed block and the slider for clamping the rails;

[0008] A grinding mechanism is arranged at the output ends of the two electric push rods for grinding the rail joints;

[0009] A moving mechanism is movably arranged on the support base and the guide rail for making the slider move back and forth to complete the docking of the rails.

[0010] In a possible design, the clamping mechanism includes a fixing plate. The fixing plate is fixedly connected to the bottom of the fixed block. A first clamping plate is fixedly connected to the bottom of the fixing plate. A chute is opened on the fixing plate, and two inner walls of the chute are slidably connected with a second clamping plate. The second clamping plate is connected with a first driving component for driving the second clamping plate to move.

[0011] In a possible design, the first driving assembly includes a second threaded rod that penetrates through the second clamping plate and is threadedly connected to the second clamping plate. One end of the second threaded rod is rotatably connected to the first clamping plate, and a second motor is fixedly connected to the bottom of the fixed plate. The output end of the second motor is fixedly connected to the other end of the second threaded rod.

[0012] In a possible design, the grinding mechanism includes two support plates, which are respectively fixedly connected to the corresponding two electric push rods. The same arc-shaped gear is fixedly connected to the tops of the two support plates. Two slide rails are symmetrically arranged on the arc-shaped gear, and two grooved pulleys are respectively connected to the two slide rails in a rolling manner. The same support is fixedly connected to the same side of the four grooved pulleys. Two notches are formed in the support. The inner walls of the tops of the two notches are respectively fixedly connected with a limiting tube. Fixed rods are slidably connected to the inner walls of the two limiting tubes. Compression springs are fixedly arranged at the tops of the two fixed rods. The tops of the two compression springs are respectively fixedly connected to the inner walls of the tops of the limiting tubes. The bottoms of the two fixed rods are respectively fixedly connected with a limiting block, and the limiting block is slidably connected to the inner wall of the corresponding notch. The same grinding machine is fixedly connected to the side where the two limiting blocks are close to each other. A second driving assembly for driving the four grooved pulleys to roll is fixedly arranged at the top of the support.

[0013] In a possible design, the second driving assembly includes a motor box fixedly arranged at the top of the support. A third motor is fixedly arranged in the motor box. A driving gear is fixedly sleeved on the output end of the third motor, and the driving gear is meshed with the arc-shaped gear.

[0014] In a possible design, the moving mechanism includes a first threaded rod that penetrates through the support seat and the slider and is threadedly connected to the slider. A first motor is fixedly connected to one side of the support seat, and the output end of the first motor is fixedly connected to the first threaded rod.

[0015] In this application, first, the two rails to be welded are located at the middle position below the equipment. Then, the two second motors are started. The two second motors respectively drive the two second threaded rods to rotate, so that the two second clamping plates threadedly connected to the two second threaded rods respectively move towards the first clamping plate direction, and then clamp the two rails respectively. After the clamping is completed, then the first motor is started. The first motor drives the first threaded rod to rotate, so that the slider sliding on the guide rail moves through the rotation of the first threaded rod, thereby moving one of the clamped rails towards the other rail direction to complete the butt joint of the two rails.

[0016] After the docking is completed, the first motor stops working, and two electric push rods are activated. The two electric push rods drive the grinding mechanism to move downward, making the grinding disc in the grinding machine on the grinding mechanism fit the rail and wait for grinding. Then, the grinding machine is started, and the grinding disc on the grinding machine grinds the rail joint. During the grinding process, the third motor in the motor box is started, and the driving gear is rotated by the third motor, so that the four grooved pulleys roll on the two slide rails arranged on the arc gear. Thus, the bracket connected by the four grooved pulleys can move along the arc of the arc gear, and the two limit blocks fixing the grinding machine slide in the limit tube due to the two fixing rods thereon, enabling the grinding machine to move up and down for yielding during the arc movement grinding process, so that the grinding machine can grind along the arc, perform all-round grinding on the rail joint, remove rust and uneven parts, and prepare for the subsequent welding work. Moreover, the compression spring arranged in the limit tube enables the grinding disc to still fit the rail during the arc movement process of the grinding machine and grind the rail.
