Description

Multi-layer scaffolding system equipped with cargo transport facilities {scaffold system}

The present invention is a multi-layer scaffolding system equipped with a cargo transport facility that can conveniently transport, unload, and move cargo through a high-rise passage of the scaffolding system through the combination of the cargo transport facility and the scaffolding device, and secure safety and stability of cargo loading. it's about

In general, in construction sites where various buildings are constructed, for the work of the inner or outer walls of the building, the work of the worker, the walking of the worker, and various materials ( A scaffolding device consisting of a scaffold for the movement of tools) is constructed.

However, until recently, when transporting various materials through the passages of each floor, the transport was done directly by the operator, so the transport operation was very inconvenient, and the physical strength was considerably consumed, which had a negative effect on the original operation.

In order to avoid these problems, the applicant of the present application is connected to the wire of the lifter mounted on the top of the scaffolding device and ascends and descends along the support pipes on both sides. referred to as a 'prior patent').

However, the prior patent has a problem in that the installation location is limited because the cargo transport facility is not only installed at the longitudinal end of the scaffolding device, that is, at the end of the passage, but also has a configuration that can be installed only at the end of the passage. If the passage is long, it causes a problem that the movement distance becomes longer when the cargo transported by the cargo elevator has to be unloaded at the end of the passage of the scaffolding device and then moved to the required place along the passage. There was also discomfort.

In addition, the prior patent describes the loading space (stop position of the cargo elevator) that occurs when the cargo elevator of the cargo transportation facility is not operating because it is structurally impossible to install a safety device at the end of the passage on each floor of the scaffolding system where the cargo transportation facility is installed There was a high risk of accidents caused by

On the other hand, in the prior patent, the carrier for loading the cargo implements the loading stand and the support in which several square frames are connected in an 'L' shape, and the support frame for supporting the cargo is formed in the longitudinal direction of the support. In the end, the carrier has no choice but to adopt a configuration in which the front is open and the rear is closed. Therefore, the carrier was interrupted by the support frame when unloading the cargo loaded on the loading platform in the direction of the support, and such obstruction is pointed out as a factor that increases the risk of safety accidents. In addition, since the upper, left, and right sides of the carrier are open, the safety and stability of cargo loading are low.

The present invention was invented to solve the problems presented in the prior patents, and an object of the present invention is to allow cargo transport facilities to be installed in several places as needed, even if the length of the scaffolding device is long, so that the cargo transported through the high-rise passage can be transported to the required place. It is meant to be moved quickly.

Another object of the present invention is to make it possible to conveniently load and unload cargo on a cargo transport facility, and to ensure safety in an unloading space generated when the carrier of the cargo transport facility is not in operation.

A scaffolding device equipped with a cargo transport facility according to the present invention comprises: a scaffold having a loading and unloading space in the front direction of the passage on each floor; Supports installed on both sides of the loading and unloading space of the scaffold; a connector for connecting and fixing the support to the scaffold; It is mounted between the both sides of the support to guide the ascent or descent to the support, and includes a rectangular box-shaped carrier with doors at the front and rear so that the cargo can be unloaded in front of the passage on each floor of the scaffold will do it with

The present invention has the effect that one or more cargo transport facilities can be installed depending on the length of the passage because the cargo transport facility can be installed on the front of the scaffolding, and the above effect is to transport the cargo transported and unloaded by the carrier of the cargo transport facility to the scaffolding passage It can be unloaded at an intermediate position rather than at the end of the vehicle, which has the effect of minimizing the transport distance of unloaded cargo.

In addition, the present invention can facilitate the disassembly and assembly of the already installed cargo transport equipment, so that the installation position can be moved at any time as needed, there is an effect that can increase the transport efficiency of the cargo.

On the other hand, in the present invention, the handrail is opened by the ascending carrier when the carrier rises and is located in the unloading space of the desired passage for cargo unloading, and the handrail closes by itself when the carrier leaves the unloading space after the unloading operation is completed. It has the effect of dispelling the risk (fall accident, etc.)

1 to 3, a scaffolding device having a cargo transport facility according to the present invention will be described with reference to FIGS. 1 to 3, the present invention provides a multi-layered scaffold 10, supports 40, 41, connector 42 and carrier 30 ) is composed of

The scaffold 10 is implemented in multiple layers of two or more layers using several horizontal and vertical frames, and a passage 11 is formed in each layer.

The supports 40 and 41 are provided on both sides at regular intervals, and the connector 42 connects the supports 40 and 41 to the scaffold 10 so that the supports 40 and 41 are provided with a scaffold ( 10) to make it stand up and fix.

The carrier 30 is in the form of a square box, and it is installed between the supports 40 and 41 and is connected with a wire to a lifter installed on the best scaffolding between the supports 40 and 41 by the forward and reverse operation of the lifter. Raises or descends in the longitudinal direction of the support, and a plurality of rollers 31 connected to the outer surfaces of the supports 40 and 41 are attached to the side surfaces, so that the lifting and lowering of the carrier 30 is performed by the supports 40, 41. It is made stably while being guided to the upper side, and an emergency stop device 35 that prevents the fall when the lifted carrier 30 falls is implemented, and the emergency stop device 35 is also present in prior patents. In the present invention, detailed description will be omitted.

And the carrier body 30 has doors 32 and 33 installed at the front and rear, so that cargo is loaded through the front door 32 and the cargo is transported through the rear door 33 through the passage of the scaffold 10 . (11) can be used to load and unload cargo quickly and conveniently. In the above, the doors 32 and 33 are double-sided sliding doors, and a latch 34 is installed at the top of the unit door on one side so that the latch 34 can fix the unit door on the other side, so that the freedom or It is designed to prevent a sudden opening to prevent a safety accident due to unexpected opening of the front door 32 or the rear door 33 when the carrier 30 is operated or loaded and unloaded.

Next, a safety device 35A is installed in the unloading space 12 formed in the passage 11 of each floor of the scaffolding device of the present invention, and the above safety device 35A is described with reference to FIGS. 4 to 8. As follows.

The safety device 35A is installed in the horizontal direction in the unloading space 12 of the passage 11 of each floor, and the first unit handrail 51 and the second unit handrail (51) on both sides of the central separation boundary part (55) 52), a bar-shaped handrail 50, a support 60 for horizontally supporting the unit handrails 51 and 52, and the support 60 are fixed, and the The outer ends of the unit handrails 51 and 52 are rotatably supported and are composed of a connector 42 connected and fixed to the scaffold 10 . Here, 'rotatable' is achieved by connecting the outer ends of the unit handrails 51 and 52 and the supporter 60 with the rotation shaft 53 .

This safety device (35A) is the inner end of the upper surface of the carrier body 30, which rises when the carrier body 30 of the cargo transport facility 20 rises, is located at the separation boundary portion 55 of the unit handrails 51 and 52. The unit handrails 51 and 52 are rotated upward to each other while pushing up (refer to (B) of FIG. 4). When the unit handrails 51 and 52 rotate upward in this way, the unloading space 12 of the passage 11 on each floor is opened, so that the cargo inside the carrier 30 can be unloaded into the passage 11 . At this time, the unit handrails 51 and 52 are maintained in an upward rotational position by the carrier 30 , and the unit handrails 51 and 52 rotate around the rotation shaft 53 of the outer end.

And when the carrier 30 is separated from the unloading space 12 after completing the unloading of the cargo, the unit rails 51 and 52 of the handrail 50 return to their original weights and return to their original state, and the loading space 12 is opened. Closed (see Fig. 4 (a)). The horizontal state in the above is made by being supported by the outer end of the support (60).

Next, as shown in FIGS. 6 and 7 , when the carrier body 30 rises by installing the opening mechanisms 70 on both sides of the rear side of the carrier body 30 of the cargo transport facility 20, the opening mechanism 70 is installed on the handrail 50 ) to prevent direct contact between the carrier body 30 and the handrail 50 by opening it. In other words, the carrier 30 cannot directly open the handrail 50.

The opening mechanism 70 is provided in a direction perpendicular to the opening piece 71 in contact with the handrail 50 when the carrier body 30 is raised or lowered, and the opening piece 71 is a support fixed to the carrier body 30 . Part (72) and. It consists of a hinge 73 for integrally connecting and coupling the opening piece 71 and the support piece 72 , and first and second stoppers 74 and 75 formed on upper and lower sides of the hinge 73 . . The first stopper 74 is formed on the upper surface of the support pipe 731 of the hinge 73 to allow the opening piece 71 to rotate only from horizontal to an upward right angle, and the second stopper 75 is It is for controlling the rotation of the opening piece 71 in the horizontal downward direction, and is formed in the rotation tube 732 of the hinge 73 .

The upper opening mechanism 70 pushes and opens the unit handrails 50 of the handrail 50 because the release piece 71 cannot be rotated in the downward direction by the second stopper 75 when the carrier body 30 rises. can do.

Adopting such an opening mechanism 70 is to unload a part of the cargo in the carrier 30 in the lower passage 11 of the scaffolding, and then move the carrier 30 to the upper floor to transport the remaining cargo to the upper floor. The unloading space of the lower passage is to return the unit handrails to their original state (horizontal return by their own weight). In this case, the carrier 30 located on the upper floor is not restricted from moving to the lower floor by the handrail 50.

The action for this is to move the carrier body 30 located on the upper floor of the scaffolding device to the lower floor, while the open piece 71 is in contact with the handrail 50, but the open piece 71 comes into contact with the handrail 50 and at the same time It rotates at right angles to the upward direction, and if the carrier body 30 is continuously lowered in this state, the end of the open piece 71 descends while in contact with the front surface of the handrail 50, so the open piece 71 is caught on the handrail 50 As a result, it is offset that prevents or disables the lowering of the carrier 30 . At this time, the second stopper 75 of the open piece 71 rotates simultaneously with the open piece 71 as shown in (B) of FIG. 7 . As described above, the upwardly rotated open piece 71 rotates downward by its own load including the weight of the second stopper 75 when it deviates from the front surface of the handrail 50 as the carrier body 30 continues to descend. to become horizontal, and this horizontal state is maintained because the second stopper 75 is in close contact with the support piece 72 of the hinge 73 . As a result, the open piece 71 acts to rotate at right angles in one direction (upward direction).

Therefore, even if the handrail 50 is horizontal and closes the unloading space 12 of the lower passage, the descent of the carrier 30 is smoothly performed without any obstruction. That is, since the opening mechanism 70 is attached to the rear side of the carrier body 30, when the opening piece 71 rotates, the carrier body 30 is positioned in front of the handrail 50, so that the lowering operation of the carrier body 30 is that there is no problem

On the other hand, in order to further secure the safety of the cargo handling space 12, another auxiliary handrail 50' having the same configuration as the handrail 50 may be installed below the handrail 50, in this case the unit handrail 51 When the auxiliary handrail 50' is opened while the carrier body 30 rises by forming a pusher 54 on the upper surface of the inner end of the 52, the pusher 54 of the auxiliary handrail 50' opens the upper handrail 50. allow it to be opened.

As mentioned above, although the present invention has been described in detail only with respect to the specific examples described, it will be apparent to those skilled in the art that various changes or modifications can be made within the spirit and scope of the present invention, and therefore such changes or modifications shall fall within the scope of the appended claims.
