Description

Technical Field

[0001] This utility model relates to the technical field of safety frames for elevator shafts; more specifically, it relates to safety frames for construction elevator shafts. Background Technology

[0002] A safety frame, also called a safety net or safety railing, is a structural device used to ensure the safety of personnel when working or constructing at heights.

[0003] A safety frame for elevator shafts is a protective structure installed inside or around elevator shafts to ensure the safety of construction and maintenance personnel. Its main function is to prevent personnel from falling from heights during elevator shaft construction, inspection, or maintenance, ensuring operational safety.

[0004] Currently, existing safety frames for elevator shafts have several drawbacks. Firstly, they are often not designed to completely fill the elevator shaft, posing a risk of falls for personnel standing on top. This reduces the equipment's practicality. Secondly, existing safety frames are not suitable for secondary reinforcement of the construction layer. Thirdly, when a large amount of material is placed on the surface, the excessive weight of the material may lead to insufficient support, further reducing the equipment's usability. Therefore, there is an urgent need for safety frames specifically designed for construction elevator shafts to address these issues. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a safety frame for construction elevator shafts to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: a safety frame for construction elevator shafts, comprising:

[0007] The car shaft has an extension structure inside, and a clamping structure is provided at the upper end of the extension structure.

[0008] The expansion structure includes a support frame, which is engaged inside the car shaft, and an mounting plate is fixedly connected to the upper end of the support frame.

[0009] The clamping structure includes threaded posts and a support plate, and there are two sets of threaded posts, which are respectively threaded to the inside of the upper end of one side of the mounting plate.

[0010] Preferably, storage slots are provided on the inner surfaces of both sides of the mounting plate, and a first motor is installed on the inner wall surface of the two sets of storage slots that are close to each other. A threaded rod is fixedly connected to the output end of the first motor, and an expansion plate is sleeved on the outer surface of the threaded rod. This design allows the threaded rod to be rotated by starting the first motor.

[0011] Preferably, the internal dimensions of the storage slot are adapted to the external dimensions of the expansion plate, a design that allows the expansion plate to move within the storage slot.

[0012] Preferably, one end of each of the two sets of threaded columns is fixedly connected to a second motor, and the two sets of second motors are installed inside the support plate. Connecting plates are fixedly connected to the upper outer surfaces of both ends of the support plate, and the outer surfaces of the two sets of connecting plates on opposite sides are respectively attached to the outer surfaces of one end of the car shaft. Concave blocks are fitted on the outer surfaces of both sets of connecting plates, and tightening bolts are threadedly connected to the middle positions of the two ends of the two sets of concave blocks. This design allows the position between the mounting plate and the support plate to be adjusted by rotating the threaded columns.

[0013] Preferably, threaded holes are formed inside the outer surfaces on both sides of one end of the mounting plate, and the outer surface of the threaded post matches the inner surface of the threaded hole. This design allows one end of the threaded post to be threaded into the inside of the threaded hole.

[0014] Preferably, the inner wall surfaces on both sides of one end of the car shaft are fixedly connected with locking blocks. The inner surfaces of the two sets of concave blocks on opposite sides are provided with locking grooves, and the inner dimensions of the locking grooves are adapted to the outer dimensions of the locking blocks. The outer surface of one end of the clamping bolt is provided with a rubber gasket. This design can fix the concave blocks by rotating the clamping bolt.

[0015] The technical effects and advantages of this utility model are as follows: By starting the first motor, the output end of the motor drives the threaded rod to rotate. At the same time, the expansion plate moves synchronously inside the storage groove due to the rotation of the threaded rod, so that the expansion plate can fill the space inside the elevator shaft. This completes the filling of the elevator shaft, avoiding the risk of falling when people stand on the equipment, and improving the practicality of the equipment to a certain extent.

[0016] By aligning the positions of the two sets of threaded posts with the positions of the threaded holes, one end of the threaded post can be inserted into the threaded hole. Then, the second motor is started, causing one end of the threaded post to rotate and be inserted into the mounting plate. When it is inserted to the appropriate position, the second motor is turned off. At this time, both sets of connecting plates are in contact with the surfaces of the two sets of locking blocks. Simultaneously, the two sets of concave blocks can be locked onto the outer surfaces of the connecting plates and locking blocks respectively. Then, the tightening bolts can be rotated inside the concave blocks so that one end abuts against the outer surface of the locking blocks. This completes the secondary reinforcement of the construction layer, preventing insufficient support when too much material is placed on the surface of the equipment. This improves the practicality of the equipment to a certain extent. Moreover, its overall structure is simple and reasonable in design, highly practical, and easy to promote and apply.

[0023] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The safety frame for elevator shafts involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Example 1, as Figure 1 and Figure 2 As shown, this embodiment proposes a safety frame for construction elevator shafts, including:

[0025] The car shaft 1 has an extension structure 2 inside, and a clamping structure 3 is provided at the upper end of the extension structure 2.

[0026] The extension structure 2 includes a support frame 21, which is engaged inside the car shaft 1, and the upper end of the support frame 21 is fixedly connected to an mounting plate 22.

[0027] Storage slots 23 are provided on the inner surface of both sides of the mounting plate 22. The inner wall surfaces of the two sets of storage slots 23 that are close to each other are equipped with first motors 24. The output end of the first motor 24 is fixedly connected to a threaded rod 25. An expansion plate 26 is fitted on the outer surface of the threaded rod 25. The outer surface of the threaded post 31 matches the inner surface of the threaded hole. The internal dimensions of the storage slots 23 are adapted to the external dimensions of the expansion plate 26.

[0028] In this embodiment, the design allows the lower end of the support frame 21 to support the mounting plate 22 through the engagement of the lower layer of the construction layer, and the output end of the first motor 24 can be started to drive the threaded rod 25 to rotate, so that the expansion plate 26 can be moved and filled according to the space inside the elevator shaft. At the same time, this design makes the expansion plate 26 and the storage groove 23 more stable when moving inside.

[0029] Example 2, as Figures 3 to 5 As shown, based on the same concept as the above embodiments, this embodiment also proposes:

[0030] The clamping structure 3 includes a threaded post 31 and a support plate 33. The threaded post 31 is provided in two sets, and the two sets of threaded posts 31 are respectively threaded to the inside of the upper end of one side of the mounting plate 22. Threaded holes are opened inside the outer surface of the two sides of one side of the mounting plate 22. This design makes the mounting plate 22 more stable because one end of the threaded post 31 is threaded to the inside of the threaded hole.

[0031] Two sets of threaded columns 31 are fixedly connected to one end of a second motor 32, and the two sets of second motors 32 are installed inside the support plate 33. Connecting plates 34 are fixedly connected to the upper outer surfaces of both ends of the support plate 33, and the outer surfaces of the two sets of connecting plates 34 that are away from each other are respectively attached to the outer surfaces of both sides of one end of the car well 1. Concave blocks 35 are fitted on the outer surfaces of both sets of connecting plates 34, and tightening bolts 36 are threadedly connected to the middle positions of both ends of the two sets of concave blocks 35. Engaging blocks are fixedly connected to the inner wall surfaces of both sides of one end of the car well 1. The two sets of concave blocks 35 are mutually... The inner surface of the outer surface away from one side is provided with a locking groove, and the inner size of the locking groove is adapted to the outer size of the locking block. The outer surface of one end of the clamping bolt 36 is provided with a rubber gasket. This design allows the connecting plate 34 to be attached to the outer surface of the locking block, and then the locking groove to be fitted onto the outer surfaces of the connecting plate 34 and the locking block. This allows the connecting plate 34 and the locking block to be clamped by rotating the clamping bolt 36. Furthermore, this design can better clamp the locking block through the good friction and elasticity of the rubber gasket itself, thereby applying longitudinal support force to the equipment.

[0032] The two sets of threaded posts 31 in this application, as well as all movable parts, require regular cleaning and maintenance, including but not limited to dust removal and lubrication.

[0033] Working principle: When using the equipment, first install it inside the elevator shaft, then snap one end of the support frame 21 onto the edge of the lower floor of the construction site. Then, start the first motor 24, causing its output end to drive the threaded rod 25 to rotate. Simultaneously, the extension plate 26 moves outwards inside the storage slot 23. When the outer surface of one end of the extension plate 26 abuts against the surface inside the elevator shaft, turn off the first motor 24. At this point, align the positions of the two sets of threaded posts 31 with the positions of the threaded holes, then insert one end of the threaded post 31 into the threaded hole. Then, start the second motor 32... The output end of the second motor 32 drives the threaded column 31 to rotate, and drives the support plate 33 and the connecting plate 34 to move synchronously. When the threaded column 31 moves to the appropriate position, the second motor 32 is turned off, so that the two sets of connecting plates 34 with their opposite sides are attached to the surfaces of the two sets of locking blocks with their opposite sides. Then, the two sets of concave blocks 35 are respectively fitted onto the outer surfaces of the two sets of connecting plates 34 and locking blocks. At this time, the tightening bolt 36 can be rotated so that the rubber gasket at its lower end abuts against the surface of the locking block. At this time, the use of the device is completed. The above is the complete working principle of this utility model.

[0034] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
