Description

Technical Field

[0001] This utility model relates to a concrete placing machine device, specifically to a horizontal construction protection component for an elevator shaft on the working floor, belonging to the field of building construction technology. Background Technology

[0002] In modern construction, concrete placing booms are an important piece of equipment widely used for concrete conveying and placement, especially in large-scale construction projects. Concrete placing booms can significantly improve construction efficiency, reduce manual labor intensity, and ensure uniform concrete distribution, thereby improving construction quality. However, in certain construction environments, traditional placing boom installation methods face many challenges, especially within elevator shafts of high-rise buildings.

[0003] Elevator shafts are typically characterized by their narrow spaces and complex structures, which significantly limits the installation and operation of traditional concrete placing booms. Existing concrete placing boom designs are primarily geared towards open spaces, failing to provide sufficient flexibility and safety for enclosed, confined environments such as elevator shafts. Due to the lack of foundation equipment specifically designed for this particular construction environment, traditional equipment not only poses safety hazards during installation but can also lead to low construction efficiency and compromised construction quality.

[0004] Currently, the design of concrete placing booms for special construction environments such as elevator shafts has not received sufficient attention and optimization. This has led many construction projects to still rely on traditional equipment or manual operation when facing these specific environments, affecting construction progress and increasing safety risks.

[0005] Therefore, the key to solving the above-mentioned technical problems lies in the urgent need for a fabric placing machine that can work efficiently and safely in confined spaces such as elevator shafts. Summary of the Invention

[0006] In view of the many defects and shortcomings of the above-mentioned background technology, this utility model has made improvements and innovations, aiming to provide a safe, reliable and easy-to-operate concrete placing boom device, which solves the limitations of traditional equipment in specific construction environments, solves the problem of difficult installation of traditional concrete placing booms, and greatly improves construction efficiency, safety and quality, thus meeting the needs of modern building construction for efficient, precise and safe equipment.

[0007] To solve the above problems and achieve the above-mentioned invention objectives, this utility model provides a horizontal construction protection component for elevator shafts on working floors, achieved through the following design structure and the following technical solution:

[0008] A protective assembly for horizontal construction in an elevator shaft at a working level includes an operating platform and a lifting assembly for lifting the operating platform, and further includes:

[0009] Positioning wheels are connected to the outer periphery of the operating table.

[0010] Warning components are installed on the control panel to alert the operator whether they have reached the designated location.

[0011] Fixed beams are connected to the bottom of the operating platform, and bases are connected to both ends of the bottom of the fixed beams;

[0012] Support components are rotatably connected to both ends of each fixed beam to match the reserved openings in the elevator shaft, so that the operating platform can be stably attached to the reserved openings of the corresponding floor.

[0013] The reset component has one end connected to the non-overlapping end of the support assembly and the other end connected to the base at the corresponding end of the bottom of the fixed beam.

[0014] The sensors are installed at both ends inside each fixed beam to monitor and sense the movement status of the corresponding support components.

[0015] The control component is installed in the middle of each fixed beam and is used to connect and coordinate with the warning components and sensors at both ends of the fixed beam.

[0016] Preferably, the warning components are connected to both ends and the middle of both sides of the control panel; the warning components include an alarm light, which is connected to the upper surface of the control panel and connected to the controller of the control component; the alarm light is used to provide early warning information to the operator.

[0017] Preferably, the warning component further includes: a follower rod, one end of which is rotatably connected to the end of the top of the control panel;

[0018] An LED is connected to the other end of the follower rod, and the LED is connected to the controller of the control component; the LED is used to determine whether the operating platform is in the raised state.

[0019] Preferably, the fixed beam is composed of two channel steels spaced apart, with the openings of both channel steels facing outwards;

[0020] The base is an I-beam or a combination of two outward-facing channel steels.

[0021] Preferably, the support component includes:

[0022] The support arm is rotatably connected to the inside of the fixed beam via a connecting assembly.

[0023] Follower pulley, the follower pulley is connected to the outer end of the support arm;

[0024] The lower inner end of the support arm is connected to the reset component.

[0025] Preferably, the reset element is a spring, with one end of the spring connected to the lower inner end of the support arm and the other end connected to the inner bottom of the base.

[0026] Preferably, the control component includes a controller and a power supply device for providing power to the controller, wherein the controller is used to receive real-time feedback information from the sensors, and after processing, adjust the working mode of the warning component according to the set logic.

[0027] Preferably, the sensing element is a photoelectric sensor, used to sense whether there is a support arm at a preset distance position in front of it.

[0028] Preferably, the positioning wheels are fixedly connected to both ends of each side of the operating table.

[0029] Preferably, the positioning wheel is adjustablely connected to both ends of each side of the operating table via a threaded rod, wherein a limiting nut for fixing the position of the positioning wheel is also threaded onto the threaded rod.

[0030] Working principle: Before use, the operator first installs the lifting assembly (10) in the elevator shaft (9) to ensure that the hoist and guide wheel are installed firmly. Then, the pull rope on the hoist passes around the corresponding guide wheel and connects it to the corresponding end of the operating table (1).

[0031] When in use, the operating platform (1) is driven by the lifting component (10) to rise. During the rise of the operating platform (1), the positioning wheel (2) contacts and connects with the inner wall of the elevator shaft (9). The follower pulley (53) gradually moves out from the original reserved opening (91). Then, the follower pulley (53) contacts and slides with the inner wall of the elevator shaft (9). At the same time, the non-follower pulley (53) end of the support arm (51) drives the follower rod (32) to move towards the alarm light (31), thereby driving the follower rod (32) to rotate on the operating platform (1), and then driving the light-emitting diode (33) connected to the end of the follower rod (32) to gradually enter the inner top of the alarm light (31).

[0032] At the same time, the support arm (51) gradually moves away from the sensor (7) until the sensor (7) can no longer sense the support arm (51) at the predetermined distance.

[0033] When the sensor (7) fails to detect the support arm (51), the sensor (7) sends a signal to the controller (81). After receiving the signal, the controller (81) processes it and sends a safety warning signal to the alarm light (31). The alarm light (31) flashes to alert the operator to pay attention to the surrounding environment. At the same time, the controller (81) sends a light switching signal to the light-emitting diode (33) to switch to the red light state.

[0034] When the operating platform (1) reaches the reserved opening (91) of the upper layer under the driving action of the lifting component (10), the follower pulley (53) gradually slides into the reserved opening (91). Under the elastic action of the reset component (6), the reset component (6) pulls the support arm (51) to reset, so that the support arm (51) and the operating platform (1) are in a parallel state. At this time, the reset component (6) pulls the support arm (51) back to its original position and blocks the front of the reset component (6). At the same time, the follower rod (32) is always in contact with the support arm (51) under the action of gravity and descends together with the support arm (51).

[0035] At the same time, after the sensor (7) senses the support arm (51), the sensor (7) sends a signal to the controller (81). After receiving the signal, the controller (81) processes it and sends a safety signal to the alarm light (31). The alarm light (31) stays on to indicate to the operator that they have reached the reserved opening (91) on the upper floor. At the same time, the controller (81) sends a light switching signal to the light-emitting diode (33) to switch to the green light state.

[0036] Finally, when the operator sees that the alarm light (31) is constantly on and the light emitted by the LED (33) is green, it can be determined that the reserved opening (91) of the upper floor has been reached, and the elevator shaft (9) above can be processed.

[0037] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0038] 1. This utility model is simple to operate, safe and reliable, and can solve the limitations of traditional equipment in specific construction environments. It can solve the problem of difficult installation of traditional concrete placing booms, and greatly improve construction efficiency, safety and quality, thus meeting the needs of modern building construction for efficient, precise and safe equipment.

[0039] 2. The fixed connection design between the operating platform and the positioning wheel in this utility model can greatly increase the stability of the operating platform during lifting and construction.

[0040] 3. The adjustable connection design of the operating platform and positioning wheels in this utility model can increase the flexibility of the device during use, and is not limited to use in elevator shafts of a single specification; at the same time, it greatly increases the stability of the operating platform during lifting and construction.

[0041] 4. The warning component of this utility model adopts the simultaneous warning function of alarm light and light-emitting diode, which significantly improves the warning effect. This dual warning method greatly enhances the vigilance of construction personnel in various working environments, effectively avoids potential safety risks, and ensures that timely countermeasures can be taken when abnormalities occur.

[0042] 5. This utility model is ingeniously designed. It uses sensors to identify the operating status of the support components and transmits the feedback information to the control components.

[0064] To make the technical means, inventive features, objectives, and effects of this utility model readily understandable, the technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0065] Example 1

[0066] As per the instruction manual Figures 1-10 As shown, a horizontal construction protection assembly for an elevator shaft at a working level includes an operating platform 1 and a lifting assembly 10 for lifting the operating platform 1, and further includes:

[0067] Positioning wheels 2 are connected to the outer periphery of the operating table 1.

[0068] Warning component 3 is installed on the control panel 1 to prompt the operator whether the designated position has been reached;

[0069] Fixed beam 4 is connected to the bottom of the operating table 1, and base 41 is connected to both ends of the bottom of fixed beam 4;

[0070] Support components 5 are rotatably connected to both ends of each fixed beam 4, and are used to match the reserved openings 91 in the elevator shaft 9 to ensure that the operating platform 1 is stably attached to the reserved openings 91 of the corresponding floor.

[0071] The reset component 6 has one end connected to the non-overlapping end of the support component 5 and the other end connected to the base 41 at the corresponding end of the bottom of the fixed beam 4.

[0072] Sensors 7 are installed at both ends inside each fixed beam 4 to monitor and sense the movement state of the corresponding support components 5.

[0073] Control component 8 is installed in the middle of each fixed beam 4 and is used to connect and coordinate with the warning components 3 and the sensors 7 at both ends of the fixed beam 4.

[0074] In this invention, the lifting assembly 10 includes a lifting machine and guide wheels fixed above the elevator shaft 9. The pull rope on the lifting machine passes around the corresponding guide wheel and connects to the corresponding end of the operating panel 1. Preferably, pull rings are also connected at the four corners of the operating panel 1 to facilitate the connection of the pull rope.

[0075] Furthermore, the warning components 3 are respectively connected to the two ends and the middle of both sides of the operating table 1; the warning components 3 include an alarm light 31, which is connected to the upper surface of the operating table 1 and connected to the controller 81 of the control component 8; the alarm light 31 is used to provide early warning information to the operator.

[0076] In this utility model, the alarm light 31 is a ring alarm light. The control component 8 controls the lighting mode of the ring alarm light 31 through circuit signals. The ring alarm light 31 can usually emit obvious visual warning signals by flashing, changing color or being constantly lit, so as to ensure that the operator can identify the status of the control panel 1 in the shortest possible time.

[0077] Furthermore, the fixed beam 4 is composed of two channel steels spaced apart, with the openings of both channel steels facing outwards;

[0078] The base 41 is an I-beam or is made of two channel steels with outward openings connected together.

[0079] Furthermore, the support component 5 includes:

[0080] The middle part of the support arm 51 is rotatably connected to the inside of the fixed beam 4 via the connecting assembly 52;

[0081] Follower pulley 53 is connected to the outer end of support arm 51;

[0082] The lower inner end of the support arm 51 is connected to the reset member 6.

[0083] Furthermore, the reset element 6 is a spring, with one end of the spring connected to the lower inner end of the support arm 51 and the other end connected to the inner bottom of the base 41.

[0084] Furthermore, the control component 8 includes a controller 81 and a power supply device 82 for providing power to the controller 81. The controller 81 is used to receive real-time feedback information from the sensor 7, and after processing, adjusts the working mode of the warning component 3 according to the set logic.

[0085] The controller 81 receives real-time feedback information from the sensor 7, processes it, and adjusts the operating mode of the warning component 3 according to the set logic. Through data analysis and judgment, the controller 81 can automatically adjust the appearance of the alarm light 31, such as brightness and flashing mode, according to different state requirements; simultaneously, it automatically adjusts the appearance of the light-emitting diode 33, such as red and green light modes; to ensure that the device can issue timely and accurate warning signals to the operator, enhancing the device's safety and responsiveness.

[0086] Furthermore, the sensing element 7 is a photoelectric sensor, used to sense whether there is a support arm 51 at a preset distance position in front of it.

[0087] In this utility model, if the sensor 7 detects that there is a support arm 51 blocking the way at a preset distance, the sensor 7 sends a signal to the controller 81. After receiving the signal, the controller 81 processes it and sends a warning light constant-on signal to the alarm light 31 of the warning component 3, which proves that the end of the support component 5 is located in the fixed opening at this time.

[0088] Conversely, if the sensor 7 does not detect any obstruction by the support arm 51 at the preset distance, the sensor 7 sends a signal to the controller 81. After receiving the signal, the controller 81 processes it and sends a flashing warning light signal to the alarm light 31 of the warning component 3. This indicates that the end of the support component 5 is in contact with the inner wall of the elevator shaft 9 and is in an ascending state.

[0089] Furthermore, the positioning wheels 2 are fixedly connected to both ends of each side of the operating table 1.

[0090] In this invention, the operating platform 1 includes a square frame and a support plate connected to the top of the square frame. Positioning wheels 2 are fixedly connected to both ends of the outer side of each crossbar of the square frame, further ensuring the stability of the operating platform 1 during the lifting and working processes.

[0091] In use, this embodiment takes the example of having six reserved openings 91 in each elevator shaft 9, and uses various compatible components to complete this fabric placing machine device for specific explanation:

[0092] Before using the above-mentioned design structure, a horizontal construction protection component for elevator shafts on the working floor needs to be manufactured and installed as a backup.

[0093] Before use, the operator first installs the lifting assembly 10 in the elevator shaft 9, ensuring that the hoist and guide wheel are installed securely. Then, the pull rope on the hoist is looped around the corresponding guide wheel and connected to the corresponding end of the operating panel 1.

[0094] When using, such as Figures 2-4 As shown, under the driving action of the lifting component 10, the operating platform 1 is driven to rise. During the rising process, the positioning wheel 2 contacts and connects with the inner wall of the elevator shaft 9, and the follower pulley 53 gradually moves out from the original reserved opening 91. Subsequently, the follower pulley 53 contacts and slides with the inner wall of the elevator shaft 9.

[0095] At the same time, the support arm 51 gradually moves away from the sensor 7 until the sensor 7 can no longer detect the support arm 51 at the predetermined distance.

[0096] When the sensor 7 fails to detect the support arm 51, the sensor 7 sends a signal to the controller 81. After receiving the signal, the controller 81 processes it and sends a safety warning signal to the alarm light 31. The alarm light 31 flashes to alert the operator to pay attention to the surrounding environment.

[0097] When the operating platform 1 reaches the reserved opening 91 of the upper layer under the driving action of the lifting component 10, the follower pulley 53 gradually slides into the reserved opening 91. Under the elastic action of the reset component 6, the reset component 6 pulls the support arm 51 to reset, so that the support arm 51 is parallel to the operating platform 1. At this time, the reset component 6 pulls the support arm 51 back to its original position, blocking the front of the reset component 6.

[0098] At the same time, after the sensor 7 detects the support arm 51, the sensor 7 sends a signal to the controller 81. After receiving the signal, the controller 81 processes it and sends a safety signal to the alarm light 31. The alarm light 31 stays on to indicate to the operator that they have reached the reserved opening 91 on the upper floor.

[0099] Finally, when the operator sees that the alarm light 31 is constantly on, it can be confirmed that the reserved opening 91 on the next floor has been reached, and the elevator shaft 9 above can be processed.

[0100] Example 2

[0101] This embodiment is basically the same as embodiment 1, except that the warning component 3 also includes a follower rod 32, one end of which is rotatably connected to the end of the top of the operating table 1.

[0102] LED 33 is connected to the other end of follow rod 32. LED 33 is connected to controller 81 of control component 8. LED 33 is used to determine whether the operating table 1 is in the raised state.

[0103] In this utility model, if the sensor 7 detects that there is a support arm 51 blocking the way at a preset distance, the sensor 7 sends a signal to the controller 81. After receiving the signal, the controller 81 processes it and sends a warning light constant light signal to the alarm light 31 of the warning component 3 and a light switching signal to the light-emitting diode 33, switching to the green light state, which proves that the end of the support component 5 is located in the fixed opening at this time.

[0104] Conversely, if the sensor 7 does not detect any obstruction by the support arm 51 at the preset distance, the sensor 7 sends a signal to the controller 81. After receiving the signal, the controller 81 processes it and sends a flashing warning light signal to the alarm light 31 of the warning component 3 and a light switching signal to the light-emitting diode 33, switching to the red light state. This indicates that the end of the support component 5 is in contact with the inner wall of the elevator shaft 9 and is in an ascending state.

[0105] In this invention, as the operating platform 1 rises, the LED 33 gradually reaches the inner top of the alarm light 31 and emits a red light, indicating that the position for processing the elevator shaft 9 has not yet been reached and the elevator is still in the rising state. When the position for processing the elevator shaft 9 is reached, the LED 33 is below the operating platform 1 and emits a green light. However, since most of the light is blocked by the operating platform 1, it can only emit a weak green light, which will not interfere with the visual operation of the elevator shaft 9.

[0106] When using, such as Figures 2-4 As shown, when the follower pulley 53 gradually moves out of the original reserved opening 91, the follower pulley 53 then contacts and slides against the inner wall of the elevator shaft 9. At the same time, the non-follower pulley 53 end of the support arm 51 drives the follower rod 32 to move towards the alarm light 31, thereby driving the follower rod 32 to rotate on the operating table 1, and then driving the light-emitting diode 33 connected to the end of the follower rod 32 to gradually enter the inner top of the alarm light 31.

[0107] When the sensor 7 no longer senses the support arm 51, the sensor 7 sends a signal to the controller 81. After receiving the signal, the controller 81 processes it and sends a light switching signal to the light-emitting diode 33 to switch to the red light state.

[0108] When the operating platform 1 reaches the reserved opening 91 of the upper layer under the driving action of the lifting component 10, the follower rod 32 is always in contact with the support arm 51 under the action of gravity and descends together with the support arm 51.

[0109] At the same time, after the sensor 7 detects the support arm 51, the sensor 7 sends a signal to the controller 81, and the controller 81 sends a light switching signal to the light-emitting diode 33 to switch to the green light state.

[0110] Finally, when the operator sees that the alarm light 31 is constantly on and the light emitted by the LED 33 is green, it can be determined that the reserved opening 91 on the next floor has been reached, and the elevator shaft 9 above can be processed.

[0111] In addition to the alarm light 31, this embodiment also includes a light-emitting diode 33, which greatly enhances the prompting effect on the operator, making it safer and more effective during use.

[0112] Example 3

[0113] This embodiment is basically the same as embodiment 2, except that the positioning wheel 2 is adjustablely connected to both ends of each side of the operating table 1 via a threaded rod, wherein a limiting nut for fixing the position of the positioning wheel 2 is also threaded onto the threaded rod.

[0114] In this utility model, the positioning wheels 2 are respectively connected to the two ends of the outer side of each crossbar of the square frame through the threaded rod. After the position of the positioning wheels 2 is adjusted, the position of the positioning wheels 2 is limited and fixed by the threaded nut connected to the threaded rod, so as to ensure the stability of the operating table 1 during the operation process and greatly improve the flexibility of the device. It is not limited to use in only one type of elevator shaft 9.

[0115] During use, this device can be flexibly assembled according to the number of reserved openings 91 opened in each elevator shaft 9 to adapt to the construction elevator shaft, and is not limited to the fixed combination of this device.

[0116] Finally, it should be noted that the concept, specific structure, and technical effects of this utility model have been clearly and completely described above in conjunction with the embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them.

Furthermore, all connections and connection relationships mentioned herein do not simply refer to direct connection of components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.
