As shown in fig. 1 and 2, an elevator hoistway operating platform in an embodiment of the present utility model is used for an elevator hoistway, and includes:
a platform plate 1;
The main beam component 2 is arranged on the upper surface of the platform plate 1 and is fixedly connected with the platform plate 1, the main beam component 2 comprises at least two groups of main beam components 20, and the two groups of main beam components 20 comprise at least four support beams 21; the supporting beam 21 includes a pressing end 211, a clamping end 212, and a hinge position 213 provided between the pressing end 211 and the clamping end 212, and the supporting beam 21 having a limit groove adapted to the clamping end 212 in the elevator shaft can rotate with the hinge position 213 as a rotation center, thereby converting a supporting state and a transferring state of the supporting beam 21. Specifically, in the supporting state, under the gravity of the platform plate 1 and the gravity of an operator, the pressing end 211 presses the platform plate 1, and the clamping end 212 is clamped in a reserved gap of an elevator shaft, so that the platform plate 1 is fixed. In the transfer state, on the one hand, the vertical lifting equipment such as the automobile crane pulls the platform plate 1 upwards, the clamping end 212 collides with the inner wall of the elevator shaft due to the reduction of the clearance in the elevator shaft, and the clamping end 212 receives downward force, so that the clamping end 212 rotates by taking the hinging position 213 as a rotation center until the supporting beam 21 is inclined to the platform plate 1, and the supporting beam 21 does not contact with the inner wall of the elevator shaft and smoothly moves along the elevator shaft; on the other hand, when the clamping end 212 is lifted to the reserved gap of the elevator shaft, the supporting beam 21 is restored to the horizontal state along with the influence of the gravity center due to the increase of the clearance in the elevator shaft, and at the moment, the operation platform falls down and is placed in the reserved gap of the elevator shaft, so that the lifting of the inner operation platform is completed.
Above-mentioned elevator well operation platform passes through joint end 212 when the headroom changes in the elevator well, can rotate with articulated position 213 as rotation center to change supporting beam 21's supporting state and transfer state, and then in the elevator engineering of installing additional, can rely on perpendicular lifting equipment such as automobile crane to hoist and mount operation platform in the concrete elevator well, have safe and reliable, easy dismounting, characteristics that reuse is high, be convenient for improve work efficiency.
In one embodiment, the main beam member 2 includes a main beam member 22 disposed along the longitudinal direction of the platform plate 1, both ends of the main beam member 22 protrude from both sides of the platform plate and are provided with hinge portions 201, and hinge portions 213 of the support beam 21 are connected to the hinge portions 201. In this way, by projecting the two ends of the main beam member 22 to the two sides of the landing plate, the hinge position 213 of the support beam 21 is rotated with respect to the hinge portion 201, and the support beam 21 can be rotated until the support beam 21 is perpendicular to the landing plate 1, reducing the clearance between the landing plate 1 and the elevator hoistway.
In one embodiment, the distance from the top pressure end 211 to the hinge location 213 is greater than the distance from the snap end 212 to the hinge location 213. Thus, the part of the supporting beam 21, which is used for pressing the platen 1, is larger than the part of the supporting beam 21, which is clamped in a preset notch of an elevator shaft, so that the dispersion of the pressing force of the supporting beam 21 on the platen 1 is ensured, and the stress is optimized.
In one embodiment, the protruding length of the main beam member 22 is adapted to the height dimension of the support beam 21. In this way, by limiting the protruding length of the main beam member 22, the clearance between the platform plate 1 and the elevator shaft is reduced, the operation tool is prevented from falling from the clearance, and the use safety factor is improved.
In one embodiment, the main beam member 22 is two section steel fixed on the platform 1 in parallel, and the support beam 21 is hinged between the two section steel by a bolt member. Thus, the lowering operation is performed by removing the latch members and lowering the platform 1 to a desired height using the vertical lifting device.
In one embodiment, the main beam member 22 is attached to the platform plate 1 by a set of bolts. Therefore, an operator can disassemble the operation platform conveniently by removing the bolt group, and each assembly is moved out of the elevator shaft respectively.
In one embodiment, the platform board 1 includes a frame 101 and a wire mesh 102 disposed on the frame 101. So, through set up wire netting 102 on support body 101, avoid there being the clearance on the support body 101, avoid operating tool to drop from the clearance, improve the use factor of safety.
In one embodiment, the platform plate 1 comprises a platform assembly 11 and a door body assembly 12 hinged with the platform assembly 11, wherein a passer-by door opening 111 is arranged in the middle of the platform assembly 11, and the door body assembly 12 is arranged at the passer-by door opening 111. Thus, by providing the door body assembly 12 at the pass door opening 111, it is convenient for an operator to open the door body assembly 12 to drop away from the pass door opening 111 when the operating platform is lifted to the top of the elevator hoistway.
In one embodiment, the platform plate 1 further comprises a sling 13 welded to the platform assembly 11. Thus, the vertical lifting equipment such as the automobile crane and the like can conveniently lift and move the vertical lifting equipment by arranging the lifting piece 13.
In one embodiment, at least three bottom beams 112 are provided on each side of the pass-through door opening 111 of the platform assembly 11, and are disposed perpendicular to the main beam members 22. In this manner, by defining a minimum number of bottom beams 112, the structural strength of the platform assembly 11 is ensured.
In one embodiment, the support beam 21 is welded from two channels. Specifically, the welding surfaces of two channel steels are arranged on the top surface and the bottom surface. Thus, the jacking end 211 and the clamping end 212 utilize the characteristic of good bending resistance of the section of the channel steel section, so that the supporting stability of the operation platform is ensured.
The technical features of the above embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
The foregoing examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model. Accordingly, the scope of protection of the present utility model is to be determined by the appended claims.
