Background technique

Elevator is a kind of vertical elevator powered by electric motor, equipped with box-shaped gondola, which is used for multi-storey buildings to take people or carry goods. There is also a step type, and the tread plate is installed on the crawler belt to run continuously, commonly known as an escalator or a moving walk. Fixed lifting equipment serving specified floors. A vertical lift has a car that runs between at least two vertical columns of rigid guide rails.

The elevator consists of multiple parts, among which people stand in the car, and the car is a box-shaped space for the elevator to carry and transport people and materials. The car generally consists of a car bottom, a car wall, a car roof, and a car door The car bottom is used for load-bearing, so the structure needs to be stable, and it is generally composed of multiple steel members welded.

The welding of the elevator car bottom generally needs to lay a layer of basic steel plate first, then weld multiple horizontal bars on the basic steel plate, then weld several vertical bars, and finally weld a new layer of basic steel plate to complete the welding, but in When welding multiple horizontal bars on the first layer, because there is no reference position positioning on the base steel plate, when placing the horizontal bars, manual or positioning machinery is required to position the horizontal bars. After positioning, ensure that the horizontal bars are equidistantly arranged before welding can be performed , the existing positioning methods generally use manual line drawing or mechanical arm transportation. The former wastes human resources and has half the efficiency, while the latter is too slow and complicated to control.

Therefore, the present invention provides an elevator car bottom combined welding auxiliary device and a splicing method thereof.

When working, the welding of the elevator car bottom generally needs to lay a layer of basic steel plate first, and then A number of horizontal bars are welded on the base steel plate, and then several vertical bars are welded, and finally a new layer of base steel plate is welded to complete the welding. However, when welding the first layer of multiple horizontal bars, since there is no reference Position positioning, resulting in the need for manual or positioning machinery to position the crossbar when placing the crossbar. After positioning, the equidistant arrangement between the crossbars can be used for welding work. The existing positioning methods generally use manual line drawing or mechanical arm transportation. The former wastes human resources and has half the efficiency, while the latter is too slow and the control is complicated. Through the setting of the conveyor belt and the receiving frame, put the horizontal bars into the receiving frame one by one, position the horizontal bars upward through the lifting component, and start the conveyor belt , with the movement of multiple groups of grabbing arms, each group of grabbing arms can grab a horizontal cylinder when it moves above the receiving frame, and then as the conveyor belt continues to move, it can grab multiple horizontal bars, And move in parallel to directly below the conveyor belt, and then only need to let the grabbing arm release the horizontal bar, so that multiple horizontal bars can be translated to the top of the basic steel plate.

Embodiment two

As shown in Fig. 5 to Fig. 8, the first comparative example, in which another embodiment of the present invention is: the bottom end of the grasping arm 4 is provided with two groups of inclined butt joint grooves 19, and the stabilizing plate 1 The bottom end is fixedly connected with an extruding frame 2, and the top of the extruding frame 2 is provided with three sets of filling grooves, and the top of the filling groove is provided with a hydraulic rod 2 23, and the outer bottom end of the extruding frame 2 is provided with three sets of Discharge port 27, the discharge port 27 communicates with the filling tank, and the discharge port 27 is inclined. During work, in the welding work, in order to ensure the quality of welding, it is generally necessary to add flux, but manually adding flux is too much. Time-consuming, through the setting of the extrusion frame 2, pour rosin flux, plastic resin and other materials into the filling groove, insert the hydraulic rod 223 back into the filling groove, when the grabbing arm 4 moves to the bottom of the extrusion frame 2 When the discharge port 27 is located, start the hydraulic rod two 23 to extend, and the solid rosin flux and plastic resin can be pressed into a solid strip through the discharge port 27, and sent into the docking groove 19, and pressed down in the later stage For steel, the strip-shaped flux will be located between the steel and the steel plate to assist the welding process, and the plastic resin has a certain degree of adhesion, which can ensure that the steel has a certain viscosity with the steel plate before welding. The telescopic rod 25 is the same as filling flux, and both need to be put into the grabbing arm 4 one by one, so the conveyor belt 6 only needs to stop once periodically to perform two operations simultaneously.

When working, the welding of the elevator car bottom generally needs to lay a layer of basic steel plate first, then weld multiple horizontal bars on the basic steel plate, then weld several vertical bars, and finally weld a new layer of basic steel plate to complete the welding , but when welding multiple horizontal bars on the first layer, because there is no reference position positioning on the base steel plate, when placing the horizontal bars, manual or positioning machinery is required to position the horizontal bars. After positioning, the horizontal bars must be arranged equidistantly For welding work, the existing positioning methods generally use manual line drawing or mechanical arm transportation. The former wastes human resources and has half the efficiency, while the latter is too slow and complicated to control. Through the settings of the conveyor belt 6 and the receiving frame 5, the The horizontal bars are put into the receiving frame 5 one by one, the horizontal bars are positioned upward by the lifting assembly, and the conveyor belt 6 is started.

Since the multiple sets of grabbing arms 4 are equidistantly arranged, the transported horizontal bars are also equidistantly placed. Through this setting, the function of quickly aligning the horizontal bars is realized, and When aligning the vertical bars, the same function can be realized by simply turning the base steel plate ninety degrees; when the grabbing arm 4 moves above the receiving frame 5, the concave part of the grabbing arm 4 will buckle the steel, and then three groups Under the adsorption of the magnet column 17, the steel is sucked, and with the friction force on the surface of the grab arm 4, the steel can be stably grasped, and then when all the grab arms 4 move to the top of the basic steel plate, the magnet column will be moved by the moving component. 17 moves upwards, because the grabbing arm 4 buckles the steel, when the magnet column 17 goes up, the steel does not move, because the magnetic force disappears, the steel will fall, and then the effect of catching and releasing the steel is achieved without using complicated The mechanical arm grabbing does not need to consume a lot of energy, and the pure mechanical movement also reduces the occurrence of failures; when the grabbing arm 4 grabs the steel and moves to the predetermined position, multiple hydraulic rods 3 are activated to drive the conveyor belt 6 to move down as a whole. Make the steel closer to the surface of the extruded steel plate. At the same time, as it moves down, the upper ejector rod 12 will be squeezed to the base steel plate. With the extrusion of the upper ejector rod 12, it will drive the magnet column 17 to move up, so that the grasping The bottom of the arm 4 loses its magnetic force. At the same time, as the magnet column 17 moves up, it will push the lever 14 and cause the other side to sink, so that the top column 15 will be pressed down, so that the steel can be pushed down. Effectively press the steel down onto the base steel smoothly, and at the same time cooperate with the setting of the buffer block 16, it is not necessary to accurately calculate the sinking depth of the lever 14, let the lifting of the buffer block 16 make up for the accuracy, and start the hydraulic pressure after the steel falls completely Rod one 3 allows the conveyor belt 6 to rise and continue to run; only need to use new conveying equipment to continuously put the steel through the entrance 20 into the lifting module 22, and then let the lifting module 22 lift the steel to the top, when the grabbing arm 4 comes At this time, with the rotation of the turnover plate 21, the steel will break away from the receiving frame 5, thereby smoothly realizing that the steel does not The process of docking and grabbing with the grabbing arm 4; through the setting of the gear-shaped transmission gear 8 and the bayonet slot 9, compared with the traditional roller conveyor belt 6, the driving force of the conveyor belt is greater, which effectively ensures stability. The effect of the transport grabbing arm 4, and the setting of the metal sheet 28 can improve the strength of the conveyor belt and reduce the deformation of the conveyor belt during transportation; the setting of the fixed table 11, the fixed table 11 and the metal sheet 28 are firmly bound Together, when the grabbing arm 4 is stressed, the force will be transmitted to the metal sheet 28 through the fixed table 11. Due to its metal material, it can effectively reduce the overall deformation of the conveyor belt 6 and ensure that the steel can be equidistant and stable. The effect of transporting to the designated place; when a group of steel products is transported, as the conveyor belt 6 continues to rotate, the next layer of steel products can be transported. Grab the parallel state of the lower part of the arm 4, when a new round begins, every group of grabbing arms 4 will pass through one side of the electric telescopic rod 25, start the electric telescopic rod 25 now, allow the electric telescopic rod 25 to elongate, Telescoping rod 25 can be contacted with inclined drive block 13, thereby pushes drive block 13 upwards, after grabbing arm 4 has rotated conveyor belt 6, now drive block 13 will protrude downwards and return to original state, by this This setting realizes the effect of continuous circulation and utilization without manual adjustment; the setting of the sliding ball 18 can reduce the friction between the magnet column 17 and the grabbing arm 4, but there is an adsorption force between the magnet column 17 and the grabbing arm 4 , so as to provide stable movement of the magnet column 17, and the setting of the positioning rod 24, when the grabbing arm 4 moves into place, first start the hydraulic rod-3 to shorten, so that the bottom end of the positioning rod 24 is combined with the positioning block 7 to cooperate with the positioning The round platform setting of block 7 can be gradually aligned with the positioning rod 24 when combined, and at the same time, during the alignment process, the conveyor belt 6 is driven to move slightly. Through this setting, it can be ensured that after each stop of the conveyor belt 6, a physical positioning is performed again The effect is to ensure that the steel can be moved to the predetermined position of the horizontal bar more accurately.
