Abstract

The invention relates to a device for experiencing the toppling of a scaffold safety railing, which belongs to a mechanical device, and in particular relates to a modular structure capable of simulating the toppling of a scaffold safety railing. The experiencer climbs up the pedal through the step beam, stands in front of the railing model, leans on the railing with both hands, starts the worm gear reducer, and drives the transmission shaft and the crank to rotate for one revolution. During this process, the connecting rod and the crank are collinear twice, Corresponding to the two extreme positions of the railing model respectively. When the connecting rod and crank are aligned for the first time, the railing model is tilted to the maximum position, and during this process, the experiencer should react correctly to escape the danger zone. When the connecting rod and the crank are collinear from the first time to the second time, the railing model returns to the vertical state from the dumped state, and the experience is complete.

Description

A modular installation for scaffolding safety railing dumping experience

technical field

The utility model belongs to a mechanical device, in particular to a modularized structure capable of simulating the falling of a scaffold safety railing.

Background technique

In the construction process of various construction sites, scaffolding is the most commonly used tool. The safety railings of the scaffolding are mainly used to protect the safety of the workers on the scaffolding. If the quality of the safety railings of the scaffolding is defective or the installation method is incorrect, then Casualties are likely to occur. At the same time, if the safety awareness of the personnel is not strong, the hazards caused by the fall of the scaffold safety railing are not enough, and the correct response and self-rescue cannot be made in time when the scaffold safety railing falls, it is easy to bring serious consequences. Therefore, increasing the awareness of construction workers on the hazards of scaffolding safety railings, and training them on how to make correct responses and postures at the moment of scaffolding safety railings falling is a necessary education to reduce the hazards caused by scaffolding safety railings falling.

In addition, the separate experience equipment is inconvenient to transport, the installation process is complicated, and it cannot be lifted repeatedly. Therefore, through the modular design, the experience equipment forms a standard experience module.

Contents of the invention

The purpose of this utility model is to design a modular scaffolding safety railing dumping experience equipment, which can enable the experiencer to experience the scene when the scaffolding safety railing is falling in a relatively real way. At the same time, the overall equipment can be easily installed, transported and replaced as a module.

In order to achieve the above object, the technical solution of the utility model is: adopt standard recyclable container as the modular outer frame; Scaffolding safety rails create a toppling effect.

Furthermore, the experience equipment is fixed in a recyclable container as a module, and bus ducts, distribution boxes and distribution ducts are set inside the standard container module, so that the equipment can directly take power from the container;

Furthermore, both ends of the connecting rod are connected by joint bearings;

Furthermore, when the crank handle rotates once, the safety railing of the scaffold can be tilted about 10-15 degrees from the vertical state.

The beneficial effect of the utility model is: through the simulation of the scene of the scaffold safety railing falling, the experiencer has an intuitive understanding of the danger of the scaffold safety railing falling. At the same time, it is more convenient to transport, install and reuse.

detailed description

As shown in Figure 1, Figure 2, Figure 3, and Figure 4, the scaffold simulation 24 and the retaining wall experience equipment 25 are fixed to the container module 18 by bolts to form a standard module, and the internal distribution box 23 is a standard module installed on the container module 18. The electric control cabinet, the power comes from the bus in the bus duct 21, and provides power to the power equipment in the retaining wall experience equipment 25 through the wires in the internal sub duct 22; the upper hoisting block 19 and the lower hoisting block 20 are respectively arranged in the container The upper and lower parts of the module 18; through the upper lifting block 19 or the lower lifting block 20, the entire module can be quickly hoisted to the designated position, and can be quickly and repeatedly hoisted;

As shown in Fig. 4 and Fig. 5, in the scaffolding simulation 24 and the retaining wall experience device 25, the bottom bracket 1 and the railing model 3 are hinged together at the railing connecting shaft 11a through the pin a2, the bottom bracket 1 is fixed on the ground, and the railing model 3. There is only one degree of freedom to rotate around the bearing center of the pin shaft a2.

As shown in Figure 4, Figure 5 and Figure 7, the railing model 3 and the connecting rod 5 are hinged together at the equipment connection shaft 11b through the pin b4, and the trajectory movement of the connecting rod 5 drives the railing model 3 to rotate at the center of the rotating shaft at the pin b4 .

As shown in Fig. 4 and Fig. 7, the connecting rod 5 and the crank 7 are hinged together at the connecting rod shaft 6 at the crank end through the pin shaft c9, and the rotation of the crank 7 makes the connecting rod 5 move on a regular track.

As shown in Fig. 4 and Fig. 6, the power mechanism 8 is connected with the worm gear reducer 15, and the worm gear reducer 15 drives the transmission shaft 14 to rotate. The crank 7 and the transmission shaft 14 are fixed together through the connecting key 16 to form an eccentric structure. The transmission shaft 14 is limited by two bearings with seat 13 and can only rotate. The bearing with seat 13, transmission shaft 14 and worm gear reducer 15 are fixed on the bottom bracket 1, and the bottom bracket 1 is fixed to the ground; the bottom frame 10 of the railing is arranged on the railing The bottom of 12, railing 12 is the main structure of railing model 3.

To sum up, when the worm gear reducer 15 drives the crank 7 and the transmission shaft 14 to rotate, the railing model 3 can be tilted forward from the vertical position by 10°-15° through the crank rocker mechanism.

Example:

The experiencer climbs up the pedal 26 through the tread beam 28, stands in front of the railing model 3, leans on the railing 12 with both hands, starts the worm gear reducer 15, and drives the transmission shaft 14 and the crank 7 to rotate for one revolution. During this process, the connecting rod 5 is collinear with the crank 7 twice, corresponding to the two extreme positions of the railing model 3 respectively. When the connecting rod 5 and the crank 7 are collinear for the first time, the railing model 3 tilts to the maximum position, and during this process, the experience personnel should react correctly to escape from the danger zone. When the connecting rod 5 and the crank 7 are collinear from the first time to the second time, the railing model 3 returns to the vertical state from the dumped state, and the experience is completed.
