Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, and relates to a protection device for a material unloading platform at a construction site. Background Art

[0002] The protections for the material unloading platforms in construction projects are various. According to the provisions of Article 6.4.8 of the "Safety Technical Code for High-place Operations in Building Construction JGJ80-2016", "The surrounding edge protection facilities should be tightly closed to prevent the slipping of personnel and materials", the surrounding edge protection measures without enclosure are strictly prohibited. However, due to various reasons such as site conditions restrictions and complex construction site situations, especially during the structural construction stage of building projects, the problems of no fixed or non-standardized protection have not been effectively solved. When transferring scattered and easily fallen materials such as templates, fasteners, and scaffolding steel pipes removed from the constructed floors, safety accidents are very likely to occur, bringing great difficulties to safety management.

[0003] An ordinary material unloading platform only simply installs side plates around the platform to reduce the falling of materials during the unloading process. This makes it difficult for operators to pick up the materials on the side plates, and it is very dangerous for operators to stand on the edge of the material unloading platform to pick up materials. At the same time, the materials on the side plates lack protection and still have the possibility of falling. Content of the Utility Model

[0004] Aiming at the technical problems in the prior art, the utility model provides a protection device for a material unloading platform at a construction site, including a material unloading platform. The material unloading platform is fixedly connected to the floor slab through two support rods. Protection nets are installed on both sides of the material unloading platform and at one end far from the floor slab. The protection device further includes a plurality of adjusting mechanisms. An inlet is formed on the enclosure of the material unloading platform and is matched with the protection net, and the inlet is located at the lower end of the enclosure. A movable door is installed in the inlet. The top end of the movable door is rotatably connected to the enclosure. The protection net is inclined and is hinged to the bottom end of the material unloading platform. The end of the protection net far from the material unloading platform is connected to the upper end of the enclosure through an adjusting mechanism. The end of the protection net far from the material unloading platform rotates around the hinge point under the drive of the adjusting mechanism, and the materials located inside the protection net open the movable door under the action of their own gravity and enter the enclosure.

[0005] Furthermore, the upper surface of the protection net is not lower than the bottom end of the inlet.

[0006] Furthermore, a plurality of rollers are rotatably arranged on the upper surface of the protection net, and the rotation directions of the plurality of rollers are the inclined directions of the protection net.

[0007] Furthermore, a protective device for a material unloading platform at a construction site further includes a locking mechanism and a pressure switch. The locking mechanism is connected to the pressure switch. The bottom end of the movable door is fixedly connected to the bottom end of the feeding port through the locking mechanism. The pressure switch is installed on the side of the movable door close to the protective net. When the pressure value of the pressure switch reaches the set value, the locking mechanism releases the locking of the movable door.

[0008] Furthermore, the adjusting mechanism includes a steel wire rope, a winding wheel, and a driving motor. The winding wheel is rotatably connected to the upper end of the enclosure through the driving motor. One end of the steel wire rope is wound around the winding wheel, and the other end is fixedly connected to the end of the protective net away from the unloading platform.

[0009] Furthermore, protective plates are provided on both sides and the end away from the enclosure of the protective net.

[0010] Furthermore, anti-rust red and white paint is applied to both the enclosure and the protective plates.

[0011] Beneficial effects:

[0012] 1. In the present utility model, through the settings of the adjusting mechanism, the feeding port, and the movable door, it is possible to conveniently transport the materials falling into the protective net into the unloading platform, avoiding the need for operators to pick up the materials personally and improving safety performance. The specific process is as follows: First, the adjusting mechanism drives the protective net to rotate around the hinge point, making it tilt towards the enclosure side. As the angle increases, the materials located in the protective net will slide down along the inclined plane under the action of their own gravity and push open the movable door to open the feeding port, thus entering the unloading platform. Combining with the inclined setting of the protective net, the risk of materials falling from the protective net can be reduced. Specifically, since the protective net initially has a certain inclined angle, most of the materials will move towards the bottom end of the inclined plane and accumulate after falling, that is, on the side close to the enclosure. At the same time, some of the accumulated materials will also directly enter the unloading platform through the feeding port under the action of their own gravity.

[0013] 2. In the present utility model, through the setting that the upper surface of the protective net is not lower than the bottom end of the feeding port, it is possible to prevent the feeding port from blocking the materials and facilitate the entry of the materials from the protective net into the unloading platform; through the setting of the rollers, it is possible to facilitate the movement of the materials on the protective net, thereby further facilitating the entry of the materials into the unloading platform.

[0014] 3. In the present utility model, through the settings of the locking mechanism and the pressure switch, it is possible to prevent the movable door from opening freely and improve safety performance. Specifically, only when the materials accumulated on the protective net reach a certain weight or when it is necessary to transport the materials on the protective net into the unloading platform, that is, when the set pressure value of the pressure switch is reached, the movable door will be pushed open by the materials to open the feeding port.

[0015] 4. In the present utility model, through the arrangement of the steel wire rope, the winding wheel and the driving motor, it is possible to conveniently control the rotation of the protective net, facilitate the movement of the material towards the retaining side, and at the same time, when the protection is not required, the protective net can be retracted as much as possible to reduce the occupied space of the entire device.

[0016] 5. In the present utility model, through the arrangement of the protective plate, the risk of the material falling from the protective net can be further reduced, and the safety performance can be improved; through the arrangement of brushing the rust-proof red and white paint, the service life of the retaining wall and the protective plate can be improved, and at the same time, the attention of the operators can be attracted by the bright and prominent color, further improving the safety performance.

[0028] The utility model provides a protective device for a material unloading platform at a construction site. As Figure 1 , Figure 2 shown, it includes a material unloading platform 1. The material unloading platform 1 is fixedly connected to the floor panel 3 through two support rods 2. Protective nets 4 are installed on both sides of the material unloading platform 1 and at one end away from the floor panel 3. To prevent materials from falling from the connection of the two protective nets 4, a flexible cloth with a certain elasticity can be specifically set at the connection, or the protective net 4 at the end away from the floor can be set in a trapezoid-like structure to ensure that the materials can smoothly enter the feeding port 6. It also includes a plurality of adjusting mechanisms. A feeding port 6 that cooperates with the protective net 4 is opened on the enclosure 5 of the material unloading platform 1, and the feeding port 6 is located at the lower end of the enclosure 5. A movable door 7 is installed in the feeding port 6. The top end of the movable door 7 is rotatably connected to the enclosure 5. The protective net 4 is inclined and is hinged to the bottom end of the material unloading platform 1. The end of the protective net 4 away from the material unloading platform 1 is connected to the upper end of the enclosure 5 through an adjusting mechanism. The end of the protective net 4 away from the material unloading platform 1 rotates around the hinge point under the drive of the adjusting mechanism. The materials located inside the protective net 4 open the movable door 7 under the action of their own gravity and enter the enclosure 5.

[0029] In this embodiment, through the settings of the adjusting mechanism, the feeding port 6 and the movable door 7, it is convenient to transport the materials falling into the protective net 4 into the material unloading platform 1, avoiding the operator from picking up by himself and improving the safety performance. The specific process is that first, the adjusting mechanism drives the protective net 4 to rotate around the hinge point, making it inclined towards the enclosure 5. As the angle increases, the materials located inside the protective net 4 will slide down along the inclined plane under the action of their own gravity and push open the movable door 7 to open the feeding port 6, so as to enter the material unloading platform 1. Combining with the inclined setting of the protective net 4, the risk of materials falling from the protective net 4 can be reduced. Specifically, since the protective net 4 has a certain inclined angle initially, most of the materials will move towards the bottom end of the inclined plane and accumulate after falling, that is, on the side close to the enclosure 5. At the same time, some of the accumulated materials will also directly enter the material unloading platform 1 through the feeding port 6 under the action of their own gravity.

[0030] In the utility model, preferably, as Figure 1 and Figure 2 shown, the upper surface of the protective net 4 is not lower than the bottom end of the feeding port 6.

[0031] In this embodiment, by setting the upper surface of the protective net 4 not lower than the bottom end of the feed inlet 6, it is possible to prevent the feed inlet 6 from blocking the material and facilitate the entry of the material from the protective net 4 into the unloading platform 1.

[0032] In the present utility model, preferably, as Figure 1 and Figure 2 shown, a plurality of rollers 8 are rotatably provided on the upper surface of the protective net 4, and the rotation directions of the plurality of rollers 8 are the inclined directions of the protective net 4.

[0033] In this embodiment, by providing the rollers 8, it is possible to facilitate the movement of the material on the protective net 4, thereby further facilitating the entry of the material into the unloading platform 1.

[0034] In the present utility model, preferably, as Figure 1 and Figure 2 shown, a construction site unloading platform 1 protection device further includes a locking mechanism 9 and a pressure switch 10. The locking mechanism 9 is connected to the pressure switch 10. The bottom end of the movable door 7 is fixedly connected to the bottom end of the feed inlet 6 through the locking mechanism 9. The pressure switch 10 is installed on the side of the movable door 7 close to the protective net 4. When the pressure value of the pressure switch 10 reaches the set value, the locking mechanism 9 releases the locking of the movable door 7, where the locking mechanism 9 can be a conventional magnetic lock, and the pressure switch 10 is a switch for controlling the on-off of the magnetic lock.

[0035] In this embodiment, by providing the locking mechanism 9 and the pressure switch 10, it is possible to prevent the movable door 7 from opening freely and improve the safety performance. Specifically, only when the material accumulated on the protective net 4 reaches a certain weight or when it is necessary to transport the material on the protective net 4 into the unloading platform 1, that is, when the set pressure value of the pressure switch 10 is reached, the movable door 7 will open the feed inlet 6 under the extrusion of the material.

[0036] In the present utility model, preferably, as Figure 1 and Figure 2 shown, the adjusting mechanism includes a steel wire rope 11, a winding wheel, and a driving motor. The winding wheel is rotatably connected to the upper end of the enclosure 5 through the driving motor. One end of the steel wire rope 11 is wound around the winding wheel, and the other end is fixedly connected to the end of the protective net 4 away from the unloading platform 1.

[0037] In this embodiment, by providing the steel wire rope 11, the winding wheel, and the driving motor, it is possible to conveniently control the rotation of the protective net 4, facilitate the movement of the material toward the enclosure 5 side, and at the same time be able to retract the protective net 4 as much as possible when not in need of protection, reducing the occupied space of the entire device.

[0038] In the present utility model, preferably, as Figure 1 andFigure 2 As shown, protective plates 12 are provided on both sides of the protective net 4 and at one end away from the retaining wall 5; antirust red and white paint is applied to both the retaining wall 5 and the protective plates 12.

[0039] In this embodiment, through the setting of the protective plates 12, the risk of materials falling from the protective net 4 can be further reduced, improving safety performance; through the setting of applying antirust red and white paint, the service life of the retaining wall 5 and the protective plates 12 can be increased, and at the same time, the attention of operators can be attracted by the bright and prominent color, further improving safety performance.

[0040] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0041] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
