Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction technology, and in particular to an elevator shaft construction operation platform device. Background Technology
[0002] Elevators are an indispensable vertical transportation tool in high-rise buildings. With the rapid development of the national economy and the continuous depletion of urban resources, high-rise and super high-rise buildings are becoming increasingly common. In many regions, the height of high-rise buildings in recent years has generally exceeded 100 meters, with some even surpassing 200 meters. For construction companies, the construction methods and safety issues related to elevator shafts are becoming increasingly prominent. During the construction of elevator shafts in high-rise buildings, workers need to complete tasks such as installing and dismantling formwork and cleaning concrete walls inside the elevator shaft. Due to the special nature of elevator shafts, a suitable standing surface cannot be provided for workers; therefore, a platform needs to be set up to meet the construction needs.
[0003] Publication No.: CN217631165U, a mobile elevator shaft construction platform includes a platform trolley and a steel platform. The base has two first omnidirectional wheels at the front bottom and two first support columns at the rear top, with handles at the top of each support column. Two second omnidirectional wheels are located on both sides of the base, and a second telescopic mechanism is located at the top of each second support column. This novel structure is stable and can fully meet the construction needs within elevator shafts. The assembly process is simple, significantly improving the assembly speed of the platform and facilitating relocation. However, in actual operation, the following problems may arise:
[0004] 1. This patent uses a movable telescopic type to place the work platform into the elevator shaft. However, the support of the equipment mainly relies on the limit plate and the keel. Not all the supporting steel frames in the elevator shaft are level with the elevator opening. If the weight on the steel plate in front of the equipment is too heavy, the equipment will tilt. Therefore, a work platform with high support capacity is required.
[0005] 2. Since the length of the keel of this equipment is fixed and its unfolding range is also fixed, it cannot be used in elevator shafts of different sizes. Therefore, a construction work platform that can automatically adapt to elevator shafts of different sizes is needed. Utility Model Content
[0006] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.
[0007] Specifically, the technical problem to be solved by this utility model is to provide an elevator shaft construction platform device to solve the technical problems of the current working platform used in elevator shafts, which has poor support effect, is prone to tilting, and cannot adapt to elevator shafts of different sizes.
[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution:
[0009] An elevator shaft construction platform device includes a support frame, a clamping and fixing mechanism fixedly installed on the top of the support frame, a telescopic fixing mechanism fixedly installed on the right side of the support frame, and a moving mechanism fixedly installed on the inner surface of the support frame.
[0010] The clamping and fixing mechanism includes a connecting frame, the bottom of which is fixedly connected to the top of the support frame. A rotating frame is rotatably mounted on the inner surface of the connecting frame via a rotating rod, and a sliding groove is provided on the outer surface of the rotating frame.
[0011] As an improved technical solution, the clamping and fixing mechanism further includes a clamping rod, the outer surface of which is slidably connected to the inner surface of the slide groove, and the inner surface of the clamping rod is threaded with a positive and negative threaded rod, and a turntable is fixedly installed at the left end of the positive and negative threaded rod.
[0012] As an improved technical solution, the telescopic fixing mechanism includes a motor, the outer surface of which is fixedly connected to the inner surface of the support frame through a fixing frame, the output end of which is fixedly mounted with a threaded shaft through a reducer, the outer surface of which is threaded with an extension rod, and a top block is fixedly mounted on the right side of the extension rod.
[0013] As an improved technical solution, the telescopic fixing mechanism further includes a support rod, the left side of which is fixedly connected to the right side of the support frame, and the inner surface of the support rod is slidably connected to the outer surface of the extension rod.
[0014] As an improved technical solution, the telescopic fixing mechanism further includes a card holder, the inner surface of which engages with the outer surface of the support rod, and a table steel plate is fixedly installed on the top of the card holder.
[0015] As an improved technical solution, the moving mechanism includes a slider, the outer surface of which is slidably connected to the inner surface of the support frame, a lifting threaded rod is fixedly installed on the top of the slider, a second turntable is threadedly installed on the outer surface of the lifting threaded rod, and the bottom of the second turntable is rotatably connected to the top of the support frame.
[0016] As an improved technical solution, the moving mechanism also includes casters, the tops of which are fixedly connected to the bottoms of the slider and the support rod, respectively.
[0017] After adopting the above technical solution, the beneficial effects of this utility model are:
[0018] 1. This utility model notation adds a design to securely fix the elevator shaft construction platform. By using a rotating frame and sliding groove in conjunction with clamping rods and positive and negative threaded rods, and by using the positive and negative threaded rods in conjunction with the No. 1 turntable, the support force of the construction platform is increased. Furthermore, by using a support frame in conjunction with the top block, the construction platform can be unfolded within the elevator shaft, avoiding the problem of the equipment tilting due to excessive weight on the platform steel plate.
[0019] 2. This utility model adds a design that allows the construction work platform to be deployed and used in elevator shafts of different sizes. This is achieved through the cooperation of the motor and threaded shaft with the extension rod and support rod, the cooperation of the extension rod and top block with the support rod and support frame, and the cooperation of the support rod and extension rod with the bracket and table steel plate.
