Abstract
Description
Technical Field
[0001] This utility model relates to the field of scaffolding, and in particular to a rapid-assembly subway construction scaffolding. Background Technology
[0002] Scaffolding is used during construction. To facilitate workers' movement, stepboards are installed on the scaffolding. However, some existing stepboards are usually hung on the sides by hooks. This method of installation can easily cause the stepboards to wobble or fall off, increasing the accident rate among construction workers. Furthermore, traditional scaffolding relies on bolts for fixing, and the parts become scattered after disassembly, taking up a lot of space for transportation and storage, and cannot be folded and stored. Utility Model Content
[0003] The purpose of this invention is to provide a quick-assembly subway construction scaffold to solve the technical problems of footboards easily shaking and falling off, and the inability to store scaffolds in the prior art.
[0004] To achieve the aforementioned objectives, the technical solution of this utility model is as follows:
[0005] A quick-assembly subway construction scaffold includes two vertical ladder frames and footboards. Automatic locking devices are installed between the two ends of the footboards and the vertical ladder frames. Each automatic locking device includes a wedge-shaped locking block at the end of the footboard. Each vertical ladder frame includes two vertical rods and several horizontal rods fixed between them. A connecting plate is installed on each horizontal rod, and a locking hole matching the taper of the wedge-shaped locking block is provided within the connecting plate. A through hole is provided in the connecting plate, communicating with the locking hole. A locking rod slides within the through hole, and the taper of the upper end of the locking rod matches the wedge-shaped locking block. The wedge-shaped locking block has a positioning hole through which the locking rod passes. A limiting groove is provided around the through hole. A limiting block is provided on the locking rod and slides within the limiting groove. A spring is sleeved on the locking rod, located between the limiting block and the limiting groove. The foot pedal achieves precise alignment and automatic locking through wedge-shaped locking blocks and locking rods, fixing the foot pedal in all directions to prevent it from shaking or coming off. To remove it, the locking rod is manually pulled down to unlock it. The structure is simple and the operation is convenient.
[0006] Preferably, a pull rod is provided between the two locking levers at one end of the foot pedal. The pull rod can pull down both locking levers simultaneously, improving work efficiency.
[0007] Preferably, a first support assembly is provided below each vertical pole. The first support assembly includes an upper sliding sleeve, a lower sliding sleeve, and three legs. The upper sliding sleeve is slidably mounted on the vertical pole, and the lower sliding sleeve is fixed to the lower end of the vertical pole. The upper sliding sleeve has a notch, and a connecting plate extends from the notch. The legs are evenly spaced along the circumference of the upper sliding sleeve, with one leg located inside the notch and fixed to the connecting plate by a locking bolt. The upper end of each leg is hinged to the upper sliding sleeve. The first support assembly can be retracted and stored, forming a triangular support structure when unfolded, further supporting each vertical pole and making the scaffolding more stable during use. When the legs are unfolded, the upper sliding sleeve can be fixed by tightening the connecting plate with the locking bolt.
[0008] Preferably, a second support assembly is provided below the foot pedal. The second support assembly includes diagonal braces that correspond one-to-one with the vertical rods. One end of each diagonal brace is hinged to the bottom of the foot pedal, and the other end is hinged to a plate. The vertical rods have slots for inserting into the corresponding plates. The diagonal braces, foot pedals, and vertical rods form a triangular support structure, further supporting the foot pedals and making them more stable.
[0009] Preferably, the foot pedals are provided with storage slots corresponding to the diagonal braces. The storage slots are used to store the diagonal braces, reducing the size of the scaffolding and facilitating transportation.
[0010] Preferably, each vertical pole is fitted with a sleeve that slides downwards, and a ground stake is vertically slidably mounted on the outer wall of the sleeve. The ground stake is connected to the ground as needed to prevent the scaffolding from tilting in strong winds.
[0011] Preferably, the pull rod has a rubber sleeve in the middle, and the rubber sleeve has anti-slip texture. The anti-slip texture is suitable for increasing the friction between the hand and the rubber sleeve, so that the pull rod is not easy to slip when force is applied downwards.
[0012] The beneficial effects of this utility model are:
[0013] 1. It features an automatic locking mechanism that enables quick assembly and locking without the need for specialized tools; wedge-shaped locking blocks and lock holes ensure precise alignment, reducing adjustment time and improving installation efficiency; and springs and limit blocks allow for quick unlocking and easy disassembly of the foot pedal.
[0014] 2. Both the first and second support components can be folded and stored for easy transportation; at the same time, they can further improve the stability of the foot pedal during use, resulting in higher safety performance. Attached Figure Description
