[0019] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0020] like Figure 1-16 As shown, this utility model discloses a tooling for installing scaffold uprights. The tooling includes four parts: a support frame 1, a slide 3, a boom 2, and a horizontal limiting rod 4.

[0021] The support frame 1 is the main load-bearing structure. This structure includes a horizontally positioned beam 1.10, with vertical support rods 1.2 welded to the upper part of the beam 1.10, and an L-shaped connecting rod 1.6 welded to the lower part of each end of the beam 1.10. Winch support plates 1.9 are symmetrically welded to both sides of the vertical support rod 1.2. Horizontal limiting support rods 1.7 are welded to the bottom of the two L-shaped connecting rods 1.6. A U-shaped support frame 1.5 with its opening facing downwards is welded to each end of the beam 1.10. The vertical support rod 1.2 resists the horizontal force generated during the installation of the scaffold uprights 6 and provides a vertical sliding track for the slide 3. A pulley frame is welded to the top of the vertical support rod 1.2, on which two symmetrically mounted steering wheels 1.1 are installed. The winch support plate 1.9 supports the winch 1.3. After the winch 1.3 is equipped with a crank handle 1.4, it can raise and lower the wire rope 5 during its rotation, controlling the scaffold uprights 6 to be installed from horizontal to vertical, and controlling the vertical displacement of the uprights 6 in the vertical state. Crank handles can be installed on both sides of the winch 1.3 for easy use. Several horizontal limiting sleeves 1.8 are welded at intervals on the outer side of the horizontal limiting support rod 1.7. Two horizontal limiting rods 4 are inserted into the horizontal limiting sleeves 1.8 from both ends of the horizontal limiting support rod 1.7 respectively. After adjusting the length, a horizontal limiting positioning pin 7 is inserted into the slot of the horizontal limiting rod 4. The outer end of the horizontal limiting rod 4 is provided with a locking interface, which locks the vertical uprights already installed on the scaffold and resists the lateral torque generated during use. The U-shaped support bracket 1.5 can hold the installed crossbar and bear the vertical load of the entire system. The open end of the U-shaped support bracket 15 is provided with a pin hole, and a pin is installed for temporary fixation after the crossbar is held.

[0022] The slide 3 includes a connecting upright 3.3, a roller assembly 3.1, a wire rope hanging ring 3.2, and a connecting arm 3.4. A set of roller assemblies 3.1 is installed on the same side of the upper and lower parts of the connecting upright 3.3. Each roller assembly includes two rollers with coplanar end faces. The distance between the two rollers is adapted to the diameter of the vertical support rod 1.2, meaning the vertical support rod 1.2 is located between the two rollers, and the two rollers can slide up and down along the vertical support rod 1.2. A second limiting plate 3.5 is welded to the outer end face of the bottom roller assembly. This second limiting plate 3.5 cooperates with the top surface of the winch support plate 1.9 of the support frame 1, restricting the slide from moving downwards towards the winch support plate 1.9. Two pairs of connecting plates 3.4 are welded to the opposite side of the roller assembly 3.1 on the connecting upright 3.3. The connecting plates 3.4 are rotatably connected to the boom frame 2 via pins. A wire rope hanging ring 3.2 is welded to the top of the connecting pole 3.3. The wire rope 5 connects the wire rope hanging ring 3.2 to the winch 1.3, so that the slide 3 can move up and down along the vertical support pole 1.2.

[0023] The boom arm 2 includes a front arm 2.3 and a rear arm 2.4 that are rotatably connected to each other. Both the front arm 2.3 and the rear arm 2.4 include two parallel horizontal arms, one above the other, with an X-shaped reinforcing rod 2.5 between them. The outer ends of the upper and lower horizontal arms of the front arm 2.3 are fitted with corresponding upper and lower vertical rod fixing claws 2.1 and 2.7. Both vertical rod fixing claws are U-shaped structures with horizontally outward-facing openings. A bolt rod is welded to the rear side of each vertical rod fixing claw. The bolt rod passes through a pad 2.2 and is then secured with a nut. The pad 2.2 is positioned between the vertical rod fixing claw and the horizontal arm. During fixing, care should be taken to ensure the vertical rod fixing claw can rotate around the pad 2.2. A pin hole is provided at the U-shaped opening end of the vertical rod fixing claw to secure the vertical rod and install a pin shaft. A limiting plate 2.6 is welded to the side of the rear arm 2.4 to control the folding angle of the boom arm 2. The rear end of the rear arm 2.4 is rotatably connected to the connecting plate 3.4 of the carriage 3 by a pin.

[0024] The horizontal limiting rod 4 is welded together from the U-shaped insert plate at the front end and the connecting pipe at the rear end. The connecting pipe has several slots processed at intervals along its axis. The connecting pipe is inserted into the horizontal limiting sleeve 1.8. After the horizontal limiting positioning pin 7 is inserted into the slot, it can lock the installed upright to adapt to different frame widths and resist the lateral torque generated during use.

[0025] First, install the support frame 1. The U-shaped support brackets 1.5 at both ends of the crossbeam 1.10 should secure the installed scaffold crossbars with pins. Adjust the position of the horizontal limit rod 4 until it secures the installed uprights, then insert the horizontal limit positioning pin 7. Securely connect the winch 1.3, with the wire rope 5 wound around it, to the winch support plate 1.9. Lead the wire rope 5 from the winch, pass it upwards over the steering wheel 1.1 at the top of the vertical support rod 1.2, and then thread it through. Connect the slide 3 to the support frame 1. Install the boom arm 2 on the slide 3, ensuring that the boom arm 2 can rotate freely.

[0026] State 1: Place the scaffolding upright 6 to be installed horizontally on the operating surface. Tie the wire rope 5 to the installation ring at the upper part of the scaffolding upright 6. Insert the bottom end of the scaffolding upright 6 into the lower fixing claw 2.7 of the vertical rod of the boom scaffold 2. Insert the bottom pin into the bottom end of the scaffolding upright 6 to lock the lower side of the U-shaped structure of the lower fixing claw 2.7, restricting the movement of the scaffolding upright 6 into the U-shaped structure. Crank the crank handle 1.4, and the wire rope 5 will lift the upper end of the scaffolding upright 6. The lower end of the scaffolding upright 6 and the lower fixing claw 2.7 will rotate together around the forearm 2.3. After the scaffolding upright 6 is erected, slightly shake the top end to lock it into the upper fixing claw 2.1 of the vertical rod and insert the pin for fixation.

[0027] State 2: Lower the wire rope 5 to connect with the lower mounting ring of the scaffold upright 6 to be installed, crank the handle 1.4 to raise the scaffold upright 6 slightly, pull out the bottom pin, and then lower the scaffold upright 6 to be installed. The lower mounting ring and the fixing claw 2.1 on the vertical pole are engaged to the state shown in State 3.

[0028] State 3: Remove the wire rope 5 from the lower mounting ring of the scaffold upright 6 to be installed, and hang it on the wire rope hanging ring 3.2 of the slide 3.

[0029] State 4: Crank the crank 1.4 to raise the slide 3 and the scaffold upright 6 to be installed, so that the bottom of the scaffold upright 6 to be installed is higher than the top of the installed upright.

[0030] State 5: Deploy the articulated boom 2, move the scaffolding upright 6 to be installed horizontally directly above the installed upright, and crank the crank handle 1.4 to lower the scaffolding upright 6 to be installed. Installation is complete.

[0031] Using this device can reduce the labor intensity of workers and lower the physical strength requirements for them.

[0032] Meanwhile, throughout the entire installation process of the scaffolding uprights 6, the uprights 6 are always fixed in place to maintain their stability and prevent accidents such as falling or being crushed.

[0033] This device is highly adaptable, and the extension length of the horizontal limit rod 4 is adjustable, which can adapt to different span requirements of existing scaffolding.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
