The lower end of the connecting rod 32 is hinged with a limiting rod 31, the hinge axis of the connecting rod and the limiting rod is horizontally arranged, and the upper end of the connecting rod 32 is fixedly connected with the lower end face of the lower mounting plate 2 or the lower end face of the upper mounting plate 1 through bolts. One end of the limiting rod 31 is abutted against the inner wall of the elevator shaft, the other end of the limiting rod is abutted against the upper end of the floor plate, one end of the limiting rod 31 abutted against the floor plate is inclined downwards, and the upper end face of the lower mounting plate 2 or the upper end face of the upper mounting plate 1 is respectively positioned on the same plane as the upper end face of the upper floor plate of the floor plate connected with the limiting rod 31. At the moment, the lower mounting plate 2 and the upper mounting plate 1 are limited in the elevator shaft through the limiting rod 31, so that the positions of the upper mounting plate 1 and the lower mounting plate 2 in the elevator shaft are fixed, the lower mounting plate 2 or the upper mounting plate 1 positioned below is detached and reinstalled in the elevator shaft of a floor needing to be constructed after the construction of the elevator shaft of one floor is completed, and scaffolds do not need to be erected in the elevator shaft layer by layer at the moment, so that the working efficiency is increased, and the cost is reduced.
As shown in fig. 1, since the limiting rod 31 only depends on the friction between the limiting rod 31 and the inner wall of the elevator shaft, the friction between the limiting rod 31 and the upper end surface of the floor plate limits the movement of the limiting rod 31, and when the downward pressure applied by the upper mounting plate 1 or the lower mounting plate 2 received by the limiting rod 31 is greater than the force received by the limiting rod 31 to obstruct the movement of the limiting rod 31, the limiting rod 31 cannot be stably supported. Therefore, the limiting rods 31 of the group of limiting mechanisms 3 are connected with a butt joint block 33 through bolts, and the butt joint block 33 is abutted against the inner wall of the elevator shaft where the elevator door opening is formed. The position of the limiting rod 31 is limited by the abutting block 33, so that the limiting rod 31 cannot move away from the elevator shaft, and the using process of the limiting mechanism 3 is more stable.
As shown in fig. 1, when the inner wall of the elevator shaft on the upper floor is machined, the limiting mechanism 3 connected to the upper mounting plate 1 or the lower mounting plate 2 needs to be detached, and then the upper mounting plate 1 and the limiting mechanism 3 connected thereto or the lower mounting plate 2 and the limiting mechanism 3 connected thereto are moved to the upper floor for installation again, which is still troublesome. Therefore, a driving mechanism 4 for driving the upper mounting plate 1 and the lower mounting plate 2 to alternately ascend and descend is connected between the two mounting plates, and the driving mechanism 4 comprises a lead screw 41 rotatably connected to the lower end of the mounting plates and a motor 42 for driving the lead screw 41 to rotate. The lower end of the screw rod 41 penetrates through the lower mounting plate 2 and is in threaded connection with the lower mounting plate 2, two limiting rings 43 (shown in figure 2) are coaxially welded at the upper end of the screw rod 41, and the upper mounting plate 1 is clamped by the two limiting rings 43. The upper end of the screw rod 41 penetrates through the upper mounting plate 1 and is coaxially connected with a worm wheel 44 by using a flat key, the motor 42 is fixed on the upper end surface of the upper mounting plate 1 by using bolts, the output shaft of the motor is coaxially connected with a worm 45 by using a flat key, and the worm 45 is meshed with the worm wheel 44. After the construction of the elevator well of accomplishing a floor, stop gear 3 that will be located the below is dismantled, utilize actuating mechanism 4 to drive the last mounting panel 1 that is located the below or mounting panel 2 rebound to the last floor that makes progress down, install stop gear 3, later dismantle stop gear 3 that will be located the top, utilize actuating mechanism 4 to make the last mounting panel 1 that is located the top or mounting panel 2 rebound to last floor down, the rebound of last mounting panel 1 and lower mounting panel 2 has been accomplished this moment, can continue the elevator well inner wall construction to last floor, and need not shift the material that is used for the construction of placing on last mounting panel 1 and lower mounting panel 2, the process that makes the construction is more convenient.
As shown in fig. 2, the upper mounting plate 1 and the lower mounting plate 2 still need to be manually removed during the process of moving upwards, which is still troublesome. Therefore, the limiting rods 31 are hinged with the lower ends of the connecting rods 32, and the hinge axes of the limiting rods and the connecting rods are horizontally arranged. At this moment, when last mounting panel 1 and lower mounting panel 2 rebound, the one end of gag lever post 31 near butt piece 33 rotates downwards, gag lever post 31 can not produce the hindrance to the rebound of guiding mechanism 5 this moment, when gag lever post 31 removed to the elevator door opening that is located the top in, the manual work is upwards rotated the one end that is close to butt piece 33 gag lever post 31, make gag lever post 31 pass the elevator door opening, guiding mechanism 5 rebound makes the both ends of gag lever post 31 fixed this moment, the ascending lifting of last mounting panel 1 and lower mounting panel 2 has been accomplished this moment, no longer need dismantle guiding mechanism 5 this moment, thereby make protection platform's use more convenient.
As shown in fig. 2, in order to make the use process of the guide mechanism 5 more convenient, springs 34 are welded to the upper ends of the side walls of the limiting rods 31, the upper ends of the springs 34 are welded to the upper mounting plate 1 or the lower mounting plate 2, and the springs 34 are located on one side of the connecting rod 32 away from the elevator door opening. The spring 34 is used for applying downward elastic force to the upward inclined end of the limiting rod 31, so that the upward inclined end of the limiting rod 31 rotates downwards, the limiting rod 31 does not need to be rotated manually to penetrate through an elevator door opening, and the use process of the guide mechanism 5 is more convenient.
As shown in fig. 2, when the guide mechanism 5 moves into the elevator door opening located above, the position of the stopper rod 31 is not limited, and the abutting block 33 easily passes through the elevator door opening and is separated from the elevator shaft, and at this time, the abutting block 33 cannot limit the position of the stopper rod 31. Therefore, the two ends of the abutting block 33 are welded with the positioning blocks 35 for limiting the position of the abutting block 33, the sum of the lengths of the two positioning blocks 35 and the abutting block 33 is larger than the width of the elevator door opening, and at the moment, the abutting block 33 cannot pass through the elevator door opening, so that the use of the guide mechanism 5 cannot be influenced.
As shown in fig. 3, since the sizes of the different elevator shafts are different, if the upper mounting plate 1 and the lower mounting plate 2 cannot contact the inner wall of the elevator shaft, the upper end surface of the upper mounting plate 1 and the upper end surface of the lower mounting plate 2 are inclined, which may affect the use. Therefore, the upper end surface of the upper mounting plate 1 and the upper end surface of the lower mounting plate 2 are both connected with a plurality of groups of guide mechanisms 5 for limiting the positions of the guide mechanisms 5, the guide mechanisms 5 are respectively connected with four inner walls in the vertical direction of the elevator shaft, and each guide mechanism 5 comprises a guide block 51 abutted against the inner wall of the elevator shaft and two guide bolts 52 for limiting the position of the guide block 51. The upper ends of the guide blocks 51 are provided with waist-shaped grooves 511 in a penetrating way, and the two guide bolts 52 are connected with the upper mounting plate 1 or the lower mounting plate 2 in a threaded way after penetrating through the waist-shaped grooves 511. The guide block 51 is used for limiting the positions of the upper mounting plate 1 and the lower mounting plate 2, so that the upper mounting plate 1 and the lower mounting plate 2 cannot rotate along the hinge axis of the connecting rod 32 and the limiting rod 31, and the use of the upper mounting plate 1 and the lower mounting plate 2 is not easily influenced.
As shown in fig. 3, the guide blocks 51 may continuously rub against the inner wall of the elevator shaft during the upward movement of the upper mounting plate 1 and the lower mounting plate 2, which may easily damage the inner wall of the elevator shaft. Therefore, the end surfaces of the guide blocks 51 far away from the screw rod 41 are all rotatably connected with rollers 53, the axes of the rollers 53 are horizontally arranged, and the side walls of the rollers are abutted against the inner wall of the elevator shaft. Sliding friction between the guide block 51 and the inner wall of the elevator shaft is changed into rolling friction by the roller 53, so that friction between the guide block 51 and the inner wall of the elevator shaft is reduced, and the inner wall of the elevator shaft is not easy to damage.
The working principle is as follows:
when in use, the limiting mechanism 3 connected with the lower mounting plate 2 is placed in an elevator shaft, then the lower mounting plate 2 is in threaded connection with the connecting rod 32, and then the position of the guide block 51 is adjusted to enable the roller 53 to be abutted against the inner wall of the elevator shaft, so that the upper end surface of the lower mounting plate 2 is kept horizontal. Then, the limiting mechanism 3 connected with the upper mounting plate 1 is arranged in the elevator shaft and positioned at the upper end of the lower mounting plate 2, the upper mounting plate 1 is connected with the limiting mechanism 3, the position of a guide block 51 connected with the limiting mechanism is adjusted, then the screw rod 41 is connected with the lower mounting plate 2, the motor 42 is mounted, and construction can be carried out at the moment. After the construction of one floor is completed, the motor 42 drives the screw 41 to rotate, so as to drive the lower mounting plate 2 to move upwards to the floor above and enable the lower end of the limiting rod 31 to pass through the elevator door opening, and then the motor 42 rotates reversely to enable the lower mounting plate 2 to move downwards so as to enable the upper end of the limiting rod 31 to be abutted against the inner wall of the elevator shaft and enable the abutting block 33 to be abutted against the inner wall of the elevator shaft. Then the motor 42 continues to rotate to move the upper mounting plate 1 upwards, so that the upper mounting plate 1 moves to be fixed at the upper floor.
The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
