Description

Technical Field

[0001] The utility model relates to the field of elevator installation, in particular to a tool for correcting bending of components on an elevator installation site. Background Art

[0002] During elevator installation, sheet metal components, channel steel, H-steel, and other materials are prone to bending and deformation, which can be difficult to correct, impacting product quality. In the past, when sheet metal parts were found to be warped on-site, they were typically hammered back to shape. This method often leaves marks and damages the paint, resulting in poor results. If large components like the car frame or counterweight frame are bent, it's impossible to correct them on-site to restore them to their factory-standard condition. The only option is to notify the manufacturer and reship the parts to meet design and operational requirements. Utility Model Content

[0003] The purpose of the utility model is to provide a tool for correcting the bending of components on the elevator installation site, so as to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above objectives, the present invention provides the following technical solutions:

[0005] A bending correction tool for components on an elevator installation site includes a support assembly and an extrusion correction device. The lower part of the support assembly has two sets of front and rear load-bearing correction lower beams, which are used to horizontally support the workpiece. The upper part of the support assembly has a load-bearing correction upper beam, which is located above and in the middle of the two sets of front and rear load-bearing correction lower beams. The extrusion correction device is located at the lower end of the load-bearing correction upper beam, and the upper and lower ends of the extrusion correction device are respectively connected to the load-bearing correction upper beam and the workpiece.

[0006] Furthermore, the load-bearing correction lower beam can be adjusted forward and backward on the support assembly.

[0007] Furthermore, at least four groups of mounting holes for inserting the load-bearing correction lower beam are provided at intervals in the front and rear of the lower portion of the support assembly.

[0008] Furthermore, an anti-displacement pin is provided at the end of the load-bearing correction lower beam.

[0009] Furthermore, the support assembly includes two left and right support frames, the lower parts of the two support frames are connected by a load-bearing correction lower beam, and the upper parts of the two support frames are connected by a load-bearing correction upper beam, and the extrusion correction device and the workpiece are located between the left and right support frames.

[0020] See also Figure 1-Figure 4 A bending correction tool for components on the elevator installation site includes a support assembly and an extrusion correction device 4. The lower part of the support assembly has two sets of front and rear load-bearing correction lower beams 2, which are used to horizontally support the workpiece 7. The upper part of the support assembly has a load-bearing correction upper beam 3, which is located above the middle of the front and rear sets of load-bearing correction lower beams 2. The extrusion correction device 4 is located at the lower end of the load-bearing correction upper beam 3, and the upper and lower ends of the extrusion correction device 4 are respectively connected to the load-bearing correction upper beam 3 and the workpiece 7.

[0021] In the above technical scheme, the utility model is provided with a support assembly, a load-bearing correction lower beam 2, a load-bearing correction upper beam 3, an extrusion correction device 4 and other structures, which can accurately and efficiently correct sheet metal parts, channel steels, H-steels and other workpieces 7 without damaging the surface morphology of the workpiece 7, and has a good shaping effect.

[0022] Continue reading Figure 1 and Figure 2 In one embodiment of the present invention, the support assembly includes two symmetrically arranged support frames 1 on the left and right. The support frames 1 are preferably an inverted T-shaped structure. The lower parts of the two support frames 1 are connected by a load-bearing correction lower beam 2, and the upper parts of the two support frames 1 are connected by a load-bearing correction upper beam 3. The extrusion correction device 4 and the workpiece 7 are located between the left and right support frames 1.

[0023] Continue reading Figure 1 and Figure 2 In one embodiment of the present invention, the load-bearing correction lower beam 2 can be adjusted forward and backward on the support assembly. Specifically, nine mounting holes 100 for receiving the load-bearing correction lower beam 2 are provided at intervals in the front and back of the lower portion of each support frame 1. The mounting holes 100 on the two support frames 1 correspond to each other, and the load-bearing correction lower beam 2 can be adjusted in its installation position by cooperating with different mounting holes 100.

[0024] It should be noted that the number and positions of the mounting holes 100 on the support frame 1 can be adjusted as needed.

[0025] Continue reading Figure 1 and Figure 2 In one embodiment of the present invention, the load-bearing correction lower beam 2 is preferably a bolt, the head of which is blocked outside the mounting hole 100, and the tail end of which is provided with an anti-displacement pin 5 to prevent the load-bearing correction lower beam 2 from falling off.

[0026] Continue reading Figure 2-Figure 4 In one embodiment of the present utility model, the lower end of the extrusion correction device 4 is connected to the workpiece 7 through the correction pad 6.

[0028] The utility model comprises a support frame 1, which comprises two components, one on each side. The support frame 1 has a mounting hole 100, which is designed to adjust the position of the load-bearing correction lower beam 2 according to the twisted position and size of the workpiece 7. The load-bearing correction lower beam 2 comprises two components, and its main function is to place the twisted component at the highest point with the lower portion suspended in the air to perform an extrusion correction function. The anti-shift axle pin 5 is used to prevent the load-bearing correction lower beam 2 from slipping or falling off during use. In addition, a load-bearing correction upper beam 3 is designed as a load-bearing fulcrum. After the workpiece 7 is placed in the correction fixture, the correction is performed and the twisted position is placed directly below the position. The correction pads 6 are used. The number or thickness of the correction pads 6 can be increased or decreased according to the twisted position and size of the extruded component to ensure that the workpiece 7 does not suffer any external damage. The utility model is also equipped with an extrusion correction device 4. The use of this device first requires visual inspection of the size of the extruded workpiece 7. Generally, a 5-10 ton hydraulic "jack" on an elevator can meet the correction requirements. In addition, to facilitate on-site calibration, a "laser level" can be used in conjunction with the calibration, so that the distortion position of the workpiece 7 can be measured after calibration to confirm whether it meets the design requirements.
