Description

Technical Field

[0001] The present application relates to the field of building construction, and in particular to a structure for erecting a lifting construction platform for an elevator shaft. Background Art

[0002] Currently, the elevator shaft is the hoistway where the elevator is installed. The size of the hoistway is determined according to the elevator selection. The elevator track and counterweight track are installed on the shaft wall, the elevator door is installed in the reserved door opening, and there is an elevator machine room at the top of the hoistway.

[0003] There are door openings on both sides of the elevator shaft. The frames of the door openings on the same side form steps. Generally, a construction platform is set up on each step. When the construction of the current step position is completed, the construction platform needs to be dismantled and re-built at the next step.

[0004] The above-mentioned prior art solutions have the following defects: during the construction of the shaft, a construction platform needs to be rebuilt at each step formed by a plurality of door opening frames, which results in excessive labor intensity for the workers. Utility Model Content

[0005] In order to reduce the labor intensity of workers, the present application provides an elevator shaft lifting construction platform erection structure.

[0006] The above technical objectives of this application are achieved through the following technical solutions:

[0007] A structure for erecting a lifting construction platform in an elevator shaft, wherein door openings are provided on both sides of the shaft. The structure is used for overlapping with steps formed by door opening frames in the shaft, and comprises a support frame and overlapping rods. The support frame is rectangular as a whole, and the overlapping rods are arranged on a frame of the support frame at the bottom. At least two overlapping rods are arranged symmetrically, and each overlapping rod is rotatably connected to the support frame, and both ends of each overlapping rod respectively abut against the support frame and the steps.

[0008] By adopting the above scheme, when the construction platform needs to be moved to the step on the upper level, the construction platform is pulled upward, and when the overlapping rod contacts the side wall of the shaft, the overlapping rod rotates, and the construction platform can be pulled to the step on the upper level, so that the overlapping rod abuts against the step on the upper level. Because the overlapping rod abuts against the support frame, the construction platform is temporarily fixed at the step on the upper level, and then people can stand on the support frame to work. If necessary, the construction platform can be moved again according to the above steps. There is no need to dismantle or reorganize the construction platform, thereby achieving the effect of reducing the labor intensity of workers.

[0009] Furthermore, a limit rod is provided on the frame at the bottom of the support frame, both ends of the limit rod are fixedly connected to the support frame, the limit rod abuts against one end of the lap rod, and the limit rod is used to limit the rotation angle of the lap rod.

[0010] By adopting the above solution, the limiting rod limits the overlapping rod to prevent the overlapping rod from rotating in the direction close to the limiting rod. Then, when the end of the overlapping rod away from the limiting rod abuts against the step, the overlapping rod cannot rotate, so that the support frame can also be limited.

[0011] Furthermore, an operating panel is fixedly connected to the top of the support frame, and the operating panel is used to support the workers to stand.

[0012] Furthermore, two side frames of the support frame close to the steps are provided with cross braces, the cross braces are arranged horizontally with the steps, both ends of the cross braces are fixedly connected to the support frame, and the cross braces are used to enhance the stability of the support frame.

[0013] Furthermore, each of the cross braces is correspondingly provided with a reinforcing rod, each reinforcing rod is vertically arranged to each cross brace, the middle portion of each reinforcing rod is fixedly connected to the cross brace, and both ends of each reinforcing rod are fixedly connected to the support frame.

[0014] By adopting the above solution, horizontal braces are arranged on the two side frames of the support frame, and then reinforcing rods perpendicular to the horizontal braces are set up, thereby dividing the entire rectangular frame into four small rectangular frames, which can increase the bearing effect of the two side frames and thus increase the stability of the support frame.

[0015] Furthermore, connecting rods are provided on both sides of the support frame where no cross brace is provided, each connecting rod is provided perpendicularly to the cross brace, both ends of each connecting rod are fixedly connected to the support frame, and the connecting rods are used to enhance the stability of the support frame.

[0016] Furthermore, stabilizing rods are provided on the frames at the top and bottom of the support frame, and both ends of each stabilizing rod are fixedly connected to the support frame, and the stabilizing rods are used to increase the stability of the support frame.

[0017] By adopting the above scheme, a connecting rod is added to the side frame of the support frame. The connecting rod can increase the load-bearing effect of the side frame, thereby increasing the stability of the support frame. The stabilizing rod has the same effect as the connecting rod, and both are used to increase the stability of the support frame, thereby making it more stable for people to stand on the support frame.

[0018] Furthermore, a rotating fastener is provided at the connection between the overlapping rod and the supporting frame, a part of the rotating fastener is fixedly connected to the overlapping rod, and another part of the rotating fastener is fixedly connected to the supporting frame, and the two parts of the rotating fastener are rotatably connected.

[0019] By adopting the above solution, the two parts of the rotating fastener can rotate relative to each other, thereby enabling the lap rod and the support frame to rotate relative to each other.

[0020] In summary, this application has the following technical effects:

[0021] By setting up the construction platform, when it is necessary to move the construction platform to the step on the upper level, the construction platform is pulled upwards, and when the lap rod contacts the side wall of the well, the lap rod rotates, and then the construction platform can be pulled to the step on the upper level, so that the lap rod abuts against the step on the upper level, and because the lap rod abuts against the support frame, the construction platform is temporarily fixed at the step on the upper level, and then the personnel can stand on the support frame to work, and if necessary, the construction platform can be moved again according to the above steps, without the need to dismantle or reassemble the construction platform, thereby achieving the effect of reducing the labor intensity of the workers;

[0022] By providing a connecting rod, the connecting rod can increase the bearing effect of the side frame, thereby increasing the stability of the support frame;

[0023] By providing the rotating fastener, the two parts of the rotating fastener can rotate relative to each other, thereby enabling the lap rod and the support frame to rotate relative to each other. BRIEF DESCRIPTION OF THE DRAWINGS

By pulling the middle part of the pulling rope 20, the two friction blocks 102 can be pulled to move in a direction close to each other. movement; a second pulling rope 40 is fixedly connected to the middle part of the pulling rope 20, and a hook 50 is fixedly connected to the end of the second pulling rope 40 away from the pulling rope 20; a locking rod is fixedly connected to the stabilizing rod 9 at the bottom of the support frame 1, and a pull ring 30 is fixedly connected to the other end of the locking rod; when the two friction blocks 102 need to be moved in a direction close to each other, the hook 50 is pulled toward the end close to the locking rod, and the hook 50 drives the second pulling rope 40 to move toward the end close to the locking rod, and then the pulling rope 20 drives the two friction blocks 102 to move toward the ends close to each other. At this time, the hook 50 is clamped together with the pull ring 30, and then the positions of the two friction blocks 102 are temporarily locked. At this time, the friction block 102 of the construction platform is lifted without generating friction with the side wall of the shaft.
