Detailed description of the invention
Below, with reference to accompanying drawing, one embodiment of the present invention is described in detail.
First, referring to figs. 1 through Fig. 7, the shield at the elevator top involved by the structure of elevator and present embodiment is described.Fig. 1 is the schematic diagram of elevator, and Fig. 2 is the schematic diagram of lift car, and Fig. 3 is the top sectional view of lift car, and Fig. 4 is the schematic diagram of Anti-fall structure, and Fig. 5 is the External view of leaf spring, and Fig. 6 is the External view of top frame, and Fig. 7 is the External view of leaf spring mounting bracket.
As shown in Figure 1, elevator is formed primarily of lift car 1, winch 2 and counterbalanced weight 3.Lift car 1 is elevated via hoist cable by winch 2 and counterbalanced weight 3 in hoist trunk.
In addition, as shown in Figure 2, lift car 1 is made up of side panel 4 and top 5.Figure 3 illustrates the general configuration at top 5.As shown in Figure 3, top 5 is made up of shield 6, top frame 7, operation at top face 8 and the anti-top shield structure 9 that drops.The shield structure 9 that drops in anti-top is made up of the integration of multiple component, and its part is arranged in top frame by installation component, and a part is arranged on shield 6.With reference to Fig. 4, the shield structure 9 that drops in anti-top is described in detail.
As shown in Figure 4, the shield structure 9 that drops in anti-top is formed by the bolt 10 be arranged on shield with by the leaf spring 12 that the otch of V-shaped engages with the screw rod of bolt.Bolt 10 is mounted and fixed on shield 6 by nut 13, is provided with for preventing nut 14a and 14b floated in the front end of the threaded portion of bolt 10.Further, when being arranged in top frame 7 by shield 6, the screw rod of bolt 10 is engaged with the otch 11 of leaf spring 12.
Such as, when being pressed upward by shield 6 in lift car 1, nut 13 abuts with the otch 11 of leaf spring, prevents shield 6 from upwards floating thus.In addition, installing or removing the occasion of shield 6, just in case when the hand of operating personnel is not arrested and makes shield 6 come off from the support of joint frame, because the otch 11 of the nut 14a with leaf spring that are arranged on bolt 10 top abuts, thus can prevent shield 6 from dropping.
In addition, as shown in Figure 5, leaf spring 12 has the notch geometry for the V-shaped engaged with bolt 10, and the central authorities of leaf spring 12 are rendered as the step shape bent highlightedly towards lift car 1 inside.By leaf spring 12 is formed as notch geometry, when shield 6 is pressed towards transverse direction in lift car 1, because the screw portion of bolt 10 abuts with the otch 11 of leaf spring, so can prevent shield 6 from misplacing in the horizontal.
In addition, by leaf spring 12 is arranged to step shape, when shield 6 is towards the outside dislocation of lift car 1, on shield 6, effect has and makes shield 6 turn back to power inside lift car 1.As shown in Figure 3, because the shield structure 9 that drops in anti-top is arranged to symmetrical shape in lift car 1, therefore when dislocation occurs shield 6 in the lateral direction, by the spring force produced by step shape of leaf spring 12, shield 6 can be suppressed to misplace in the lateral direction, shield 6 can be made to turn back to original position.
In addition, when elevator travels or when passenger takes into elevator etc., shield may misplace because of vibration, and in the present embodiment, because the inner side of shield 6 towards lift car 1 presses, so can also prevent shield 6 from misplacing because of vibration of elevator by leaf spring 12 all the time.
Therefore, to drop structure 9 by arranging anti-top shield, shield 6 can be suppressed to move up in above-below direction, fore-and-aft direction and right and left.That is, when shield 6 moves towards above-below direction, because nut 13 or nut 14 abut with otch 11, so shield 6 can be suppressed to move at above-below direction.In addition, when shield 6 moves to front-rear direction, because bolt 10 abuts with otch 11, so shield 6 can be suppressed to move in the longitudinal direction.Further, when shield 6 moves to left and right direction, by the spring force produced by step shape of leaf spring 12, shield 6 can be suppressed to move in the lateral direction.
As mentioned above, according to the present embodiment, only a pair anti-top shield need be set drop structure 9 in any one direction in the Width of elevator or depth direction.Not needing to arrange polytype parts such as maintenance spring and Anti-fall block piece, by arranging a pair Anti-fall block piece, just can prevent shield 6 from dropping.
In addition, when installing shield 6, in lift car 1, shield 6 is placed on joint frame.Now, may occur that bolt 10 and leaf spring 12 interfere and make the situation that shield 6 cannot be installed.In order to prevent interfering when installing shield, in the present embodiment, as shown in Figure 6, top frame 7 side is provided with elongated hole 15.
So, by arranging elongated hole 15 in top frame 7 side, when installing shield 6, correspondingly the position of leaf spring mounting bracket 16 can be configured in the outside of lift car 1 with this elongated hole.Such as, after being placed in joint frame by shield 6, in lift car 1, make leaf spring mounting bracket 16 slide the amount corresponding to elongated hole, carry out the engaging of bolt 10 and leaf spring 12 thus.Thereby, it is possible to prevent bolt 10 and leaf spring 12 from interfering.
In addition, owing to being provided with the otch 11 of V-shaped on leaf spring 12, therefore by making leaf spring mounting bracket 16 slide, can position the position of shield 6.That is, by arranging the otch 11 of V-shaped on leaf spring 12, contraposition (namely so-called alignment) can be carried out to the center in the center of shield 6 and lift car, shield 6 can be installed easily thus.After the installation of shield 6 terminates, fix leaf spring mounting bracket 16 by screw 17.
It should be noted that, in the present embodiment, leaf spring 12 arranges the otch 11 of V-shaped, but the present invention is not limited thereto, the otch 11 of U-shaped also can be set.
It should be noted that, be black by the color settings of screw 17, and make when passenger observes top, screw 17 can not have influence on the ornamental of top.
According to said structure, the top frame 7 of elevator has a pair opposite disposed anti-top shield for hanging holding shield 6 to drop structure 9, this anti-top shield structure 9 that drops has bolt 10 (the first component of the present invention) and leaf spring 12 (second component of the present invention), this bolt 10 is arranged on shield 6, and this leaf spring 12 to be arranged in top frame 7 and to engage with bolt 10.By installing shield 6 on bolt 10, shield 6 can be suppressed to move at above-below direction, by making bolt 10 engage with leaf spring 12, shield 6 can be suppressed to move at fore-and-aft direction, and by the spring force of leaf spring 12, shield 6 can be suppressed to move at left and right directions.So, by making a pair anti-top shield structure 9 that drops have the function preventing shield from floating and the function preventing shield from misplacing simultaneously, can prevent shield from dropping.
