Description

Technical Field

[0001] This utility model relates to the field of elevator car processing technology, and in particular to a positioning tool for assembling elevator car panels. Background Technology

[0002] The steel plates of the elevator car are typically fixed to the car frame by riveting or welding. During riveting or welding, multiple operators are often required to position the plates first, and this positioning process takes a considerable amount of time, undoubtedly increasing the workload on the operators. Furthermore, there is the issue of poor positioning accuracy. Riveting, which involves pre-drilling holes and then fixing the plates, only requires fixing a few points initially to achieve positioning before the entire assembly is riveted. However, when using welding, if the positional accuracy of the steel plates is significantly inaccurate, it directly affects the car's external dimensions and makes subsequent adjustments and corrections difficult. Utility Model Content

[0003] This utility model provides a positioning tool for assembling elevator car panels, which solves the shortcomings of the prior art, such as the inconvenience of positioning and poor positioning accuracy when fixing iron plates, and has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted:

[0005] A positioning tool for assembling elevator car panels includes a base. Optionally, the lower end of the base can be equipped with multiple threaded support legs, and a spirit level is installed on the base to adjust the levelness of the base via the support legs, thereby ensuring accuracy during panel assembly. A pair of vertical plates are welded to the base, and connecting side plates are bent at the lower ends of the vertical plates. The lower ends of the connecting side plates are welded to the base. A supporting horizontal plate is installed at the lower end of the vertical plates via a pair of screws, providing support for the lower end of the panel.

[0006] A pair of connecting pipes are welded to the vertical plate. The outer ends of the connecting pipes are threaded to end caps, and push-pull rods are threaded through the end caps. A magnet is located on the inner end of the push-pull rod, and an inner disc is connected to the outer end of the push-pull rod via a pin. An outer pull plate is fitted onto the outer end of the push-pull rod, and a locking nut is threaded to the outer end of the push-pull rod. The inner end of the locking nut acts on the outer pull plate. The magnets attract the iron plate, thus fixing it in place. The magnets are mounted on a movable push-pull rod, facilitating the removal of the magnets from the iron plate.

[0007] Furthermore, in order to accommodate the fixing operation of the iron plate at different heights, a vertical hole is opened at the lower end of the vertical plate, and a screw is inserted into the vertical hole. An inner plate strip is fitted on the screw, which is located on the inner side of the vertical plate. A lifting handle is welded on the inner plate strip to facilitate the adaptive adjustment of the height of the supporting horizontal plate.

[0008] Furthermore, to facilitate the separation of the magnet from the iron plate, a rectangular hole is provided on the outer horizontal plate, and a spreading rotating plate is provided inside the rectangular hole. The spreading rotating plate has protrusions on both sides, which are welded to the outer horizontal plate. A hinge shaft is provided at the outer end of the protrusion, and the hinge shaft passes through the spreading rotating plate. The two ends of the hinge shaft are connected to limit nuts by threads to limit the axial movement of the hinge shaft. The inner end of the spreading rotating plate acts on the outer wall of the vertical plate. When separating, the magnet and the iron plate can be separated by rotating the spreading rotating plate.

[0009] Furthermore, a handle is provided on the outer end of the rotating plate to facilitate the rotation of the rotating plate.

[0010] Furthermore, to facilitate the positioning of the left and right sides of the iron plate, ensuring that the centerline of the iron plate in the width direction aligns with the centerline of the base, an outward-extending shaft is welded to the upper end of the vertical plate. A limiting arm is rotatably mounted on the outward-extending shaft, and an end nut is threaded to the outer end of the outward-extending shaft. The end nut is located outside the limiting arm, and a slotted hole is provided on the limiting arm. A rotating inner shaft passes through the slotted hole, and a pair of side plates are provided on the limiting arm. Long slotted holes are provided on the side plates, and an inner block is provided at the outer end of the rotating inner shaft. The inner block is located between the side plates, and multiple locking screws are provided on both sides of the inner block. The locking screws pass through the long slotted holes and are threaded to a tightening nut. The inner end of the tightening nut acts on the side plate, and a side pressure wheel is provided at the outer end of the rotating inner shaft. The side pressure wheel acts on both sides of the iron plate, thereby achieving the purpose of calibrating the position of the iron plate.

[0011] Furthermore, a gripping rod is welded to the inner end of the limiting arm to facilitate rotation of the limiting arm.

[0012] Furthermore, a stop pin is provided on the lower side of the limiting arm, and the stop pin is welded to the vertical plate to prevent the limiting arm from rotating excessively.

[0013] The advantages of the above technical solution are:

[0014] This invention facilitates the fixing of iron plates and allows for position adjustment based on the fixing height of the iron plates. Furthermore, it improves the accuracy of iron plate fixing and reduces the difficulty of fixing the iron plates. Attached Figure Description

[0019] Figure 4 A three-dimensional structure of one embodiment is shown. Figure 2 . Detailed Implementation

[0020] like Figures 1-4 As shown, a positioning tool for assembling elevator car panels includes a base 1. A pair of vertical plates 2 are welded to the base 1, and a supporting horizontal plate 25 is mounted on the lower end of the vertical plates 2 by a pair of screws 22. Optionally, multiple casters are installed on the base 1 to facilitate the movement of the positioning tool. Further optionally, multiple adjustable support legs can be provided on the base 1 to adjust the levelness of the base 1. For ease of adjustment, a spirit level can be used for calibration.

[0021] In this embodiment, the operator places the lower end of the iron plate on the support horizontal plate 25 and makes the outer wall of the iron plate tightly adhere to the vertical plate 2. Then, the iron plate is moved to the car frame and welded or riveted to fix it.

[0022] In some embodiments, a vertical hole 21 is provided at the lower end of the vertical plate 2, a screw 22 is inserted into the vertical hole 21, an inner strip 23 is fitted on the screw 22, the inner strip 23 is located on the inner side of the vertical plate 2, and a handle 24 is welded on the inner strip 23.

[0023] In this embodiment, during installation, the operator first adjusts the height of the supporting horizontal plate 25 according to the fixed height of the iron plate. After adjustment, the supporting horizontal plate 25 can be fixed by screws 22.

[0024] A pair of connecting pipes 4 are welded on the vertical plate 2. The outer end of the connecting pipe 4 is connected to an end cap 40 by a thread. A push-pull rod 41 is installed on the end cap 40. A magnet is installed on the inner end of the push-pull rod 41. An inner plate 42 is connected to the outer end of the push-pull rod 41 by a pin. An outer pull plate 44 is sleeved on the outer end of the push-pull rod 41. A locking nut 43 is connected to the outer end of the push-pull rod 41 by a thread. The inner end of the locking nut 43 acts on the outer pull plate 44.

[0025] In this embodiment, the lower end of the iron plate is placed on the supporting horizontal plate 25, and the magnet is moved inward to attract the iron plate, thereby making the outer wall of the iron plate tightly adhere to the vertical plate 2. This method ensures the stability of the iron plate during installation.

[0026] In some embodiments, a rectangular hole 45 is provided on the outer pull horizontal plate 44, and a spreading rotating plate 48 is provided in the rectangular hole 45. A handle 49 is provided on the outer end of the spreading rotating plate 48. A protrusion 46 is provided on both sides of the spreading rotating plate 48. The protrusion 46 is welded to the outer pull horizontal plate 44. A hinge shaft 47 is provided on the outer end of the protrusion 46. The hinge shaft 47 passes through the spreading rotating plate 48. The two ends of the hinge shaft 47 are connected to limit nuts by threads to limit the axial movement of the hinge shaft 47. The inner end of the spreading rotating plate 48 acts on the outer wall of the vertical plate 2.

[0027] In this embodiment, when the magnet and the iron plate are disconnected, the operator rotates the opening plate 48, and the rotation of the opening plate 48 will make it horizontal, and its inner end will act on the outer wall of the vertical plate 2. When the opening plate 48 rotates, the outer horizontal plate 44 will be pulled away from the vertical plate 2, thereby making the magnet detach from the iron plate.

[0028] In some embodiments, an extension shaft 3 is welded to the upper end of the vertical plate 2, a limiting arm 30 is rotatably mounted on the extension shaft 3, a holding rod 31 is welded to the inner end of the limiting arm 30, an end nut 32 is threaded to the outer end of the extension shaft 3, the end nut 32 is located outside the limiting arm 30, a strip hole 33 is opened on the limiting arm 30, a rotating inner shaft 37 passes through the strip hole 33, a pair of side plates 34 are provided on the limiting arm 30, an elongated hole 35 is opened on the side plate 34, an inner block 36 is provided at the outer end of the rotating inner shaft 37, multiple locking screws 38 are provided on both sides of the inner block 36, the locking screws 38 pass through the elongated hole 35, a tightening nut is threaded to the locking screws 38, the inner end of the tightening nut acts on the side plate 34, a side pressure wheel 39 is provided at the outer end of the rotating inner shaft 37, a stop pin is provided on the lower side of the limiting arm 30, and the stop pin is welded to the vertical plate 2.

[0029] In this embodiment, when calibrating the position of the iron plate in the width direction, the operator first adjusts the position of the inner block 36 according to the width of the iron plate. During adjustment, the tightening nut is loosened first, and then the inner block 36 is moved. During the movement, the side pressure roller 39 on it will move along with it. After the adjustment is completed, the position of the inner block 36 is fixed by tightening the nut. After fixing, the limiting arm 30 is rotated. During the rotation, the outer periphery of the side pressure roller 39 will act on both sides of the iron plate to achieve the purpose of calibrating the position of the iron plate.
