Description

Technical Field

[0001] This invention relates to a construction operation platform, and more particularly to a building front lifting construction operation platform. Background Technology

[0002] When construction workers are painting walls, they usually stand on ladders or work platforms. Work platforms offer more space to move around than ladders and do not require help from colleagues to hold the ladder, making them more convenient to use.

[0003] However, existing operating platforms generally have relatively simple functions, cannot adjust the height according to the needs of workers, and lack safety devices such as guardrails, which cannot guarantee the safety of workers and is quite dangerous. In addition, there is no device for transporting mud, so if workers run out of mud during the wall painting process, they need to climb down to replenish it, which is quite troublesome and affects work efficiency. To address the above problems, a building front lifting construction operating platform with adjustable height and high work efficiency has been designed. Summary of the Invention

[0004] To overcome the shortcomings of existing operating platforms, which are generally simple in function, cannot be adjusted in height according to the needs of workers, and lack a device for transporting mud, thus affecting work efficiency, the technical problem of this invention is to provide a building front lifting construction operating platform that can adjust its height and has high work efficiency.

Those skilled in the art will understand that terms such as "above," "below," "upward," "downward," etc., are used to describe the drawings and not to indicate a limitation on the scope of the invention as defined by the appended claims. Any numerical designations such as "first" or "second" are merely illustrative and not intended to limit the scope of the invention in any way.

[0033] Example 1

[0034] A type of lifting construction operation platform for the front of a building, such as Figures 1-13As shown, the device includes a limit block 1, a support frame 2, a dual-axis reduction motor 3, a slide bar 4, a spiral shaft 5, a support column 6, a first limit rod 7, a load-bearing plate 8, a slider 9, a first connecting rod 10, a second connecting rod 11, a rotating shaft 12, a ladder 13, a material blocking mechanism 14, and a feeding mechanism 15. The limit block 1 has a support frame 2 in its center, and the support frame 2 has a dual-axis reduction motor 3 in its center. Slide bars 4 are slidably mounted on both the left and right sides inside the limit block 1. Spiral shafts 5 are rotatably mounted on the middle of both the left and right sides of the support frame 2. The inner ends of the spiral shafts 5 are connected to the output shafts of the dual-axis reduction motor 3, and the outer sides of the spiral shafts 5 are threadedly connected to the middle of the adjacent slide bars 4. Support columns 6 are located on the middle of both the left and right sides of the top of the limit block 1. First limit rods 7 are slidably mounted inside the support columns 6. A load-bearing plate 8 is provided between the top of a limiting rod 7. Workers can stand on the top of the load-bearing plate 8. When the load-bearing plate 8 moves upward, it can move the workers upward, which facilitates the workers' construction. Multiple strip holes are spaced apart on the load-bearing plate 8. Slider 9 is symmetrically slidably provided on the front and rear sides of the bottom of the load-bearing plate 8. A first connecting rod 10 is rotatably provided between the left slider 9 and the right sliding rod 4. A second connecting rod 11 is rotatably provided between the right slider 9 and the left sliding rod 4. A rotating shaft 12 is rotatably provided between the middle of the second connecting rod 11 and the middle of the adjacent first connecting rod 10. A ladder 13 for workers to climb onto the load-bearing plate 8 is provided on the rear left side of the load-bearing plate 8. A material blocking mechanism 14 is provided at the bottom of the load-bearing plate 8. A feeding mechanism 15 is provided on the front side of the load-bearing plate 8.

[0035] The material blocking mechanism 14 includes a second limiting rod 140, a baffle plate 141, a push block 142, and a compression spring 143. The second limiting rod 140 is provided on both the front and rear sides of the bottom of the load-bearing plate 8. The baffle plate 141 is provided between the lower parts of the second limiting rod 140. When workers are working, mud may fall down. The baffle plate 141 can block the mud and prevent it from falling onto the dual-shaft reduction motor 3 and the spiral shaft 5. The push block 142 is slidably provided between the right sides of the second limiting rod 140. When the worker pushes the push block 142 to the left, the mud on the baffle plate 141 will be pushed to the left. The push block 142 contacts the top of the baffle plate 141. The second limiting rod 140 is wrapped with a compression spring 143. The two ends of the compression spring 143 are connected to the second limiting rod 140 and the push block 142, respectively.

[0036] The feeding mechanism 15 includes a third connecting block 150, a third limiting rod 151, a first electric push rod 152, a lifting block 153, a pressure sensor 154, and a buzzer 155. The third connecting blocks 150 are symmetrically arranged on the left and right sides of the front of the load-bearing plate 8. The third limiting rod 151 is located at the bottom front side of the third connecting block 150 on the left side, and the first electric push rod 152 is located at the front side of the third connecting block 150 on the right side. The lifting block 153 is slidably arranged on the upper part of the third limiting rod 151. The right side of the lifting block 153 is connected to the bottom of the telescopic rod of the first electric push rod 152. Workers can place the bucket containing mud on the top of the lifting block 153. The first electric push rod 152 can be activated to drive the lifting block 153 to move up and down, thereby facilitating the transportation of mud. The pressure sensor 154 is located on the top middle side of the lifting block 153, and the buzzer 155 is located on the top front side of the third connecting block 150 on the left side.

[0037] When workers need to use the building's front-facing lifting construction platform, they first press the main power switch to power on the platform, activating the pressure sensor 154. Then, the worker can climb to the top of the load-bearing plate 8 using ladder 13, place the necessary tools on top, and press the motor switch 132 once. The motor switch 132 sends a signal, which the control module receives and controls to rotate the dual-axis reduction motor 3 forward. The output shaft of the dual-axis reduction motor 3 drives the spiral shaft 5 to rotate forward, thereby causing the slide rod 4 to move inward. The slide rod 4 causes the first connecting rod 10 and the second connecting rod 11 to rotate, thus causing the slider 9 to slide inward, which in turn moves the load-bearing plate 8 upward, thereby lifting the worker upward. When the supporting plate 8 rises to the appropriate height, the worker presses the motor switch 132 again. The motor switch 132 sends a signal, and the control module, upon receiving the signal, controls the dual-axis reduction motor 3 to stop working. Then, the worker can complete the wall painting work on the supporting plate 8. When slurry falls down, it will fall through the strip holes on the supporting plate 8 onto the baffle plate 141, thus preventing the slurry from falling onto the spiral shaft 5 and the dual-axis reduction motor 3. When the slurry is used up, the worker can place the empty bucket on top of the lifting block 153 and then press the first switch 133 once. The first switch 133 sends a signal, and the control module, upon receiving the signal, controls the first electric push rod 152 to extend for 3 seconds. The extension rod of the first electric push rod 152 drives the lifting block 153 and... Pressure sensor 154 moves downwards, and the third limit rod 151 acts as a guide. After 3 seconds, the control module controls the first electric push rod 152 to stop working. Then, other workers remove the empty bucket, fill it with mud, and place the bucket full of mud on top of the lifting block 153. At this time, pressure sensor 154 senses the pressure and sends a signal. After receiving the signal, the control module controls buzzer 155 to work for 3 seconds, thus reminding the workers that the mud has been filled. After 3 seconds, the control module controls buzzer 155 to stop working. At this time, the worker can press the first switch 133 again. The first switch 133 sends a signal, and after receiving the signal, the control module controls the first electric push rod 152 to shorten the time by 3 seconds. The telescopic rod of the first electric push rod 152 drives the lifting block 153 and pressure sensor 154 to move upwards and reset. After 3 seconds, the control module controls the first electric push rod 152 to stop working. Then, the worker can remove the bucket full of mud and resume the wall painting work. This process is repeated. When the work is completed, the worker presses the motor switch 132 once. The motor switch 132 sends a signal, and after receiving the signal, the control module controls the dual-axis reduction motor 3 to reverse. The output shaft of the dual-axis reduction motor 3 drives the spiral shaft 5 to reverse, thereby driving the slide rod 4 to move outwards and reset. The slide rod 4 drives the first connecting rod 10 and the second connecting rod 11 to rotate and reset, thereby driving the slider 9 to slide outwards and reset, which in turn drives the load-bearing plate 8 to move downwards and reset, thus driving the worker to move downwards.When the load-bearing plate 8 descends to the appropriate height, the worker presses the motor switch 132 again. The motor switch 132 sends a signal, which the control module receives and stops the dual-axis reduction motor 3. The worker can then climb down the ladder 13 to return to the ground, remove the tools from the load-bearing plate 8, and push the push block 142 to the left. This compresses the spring 143, and releasing the push block 142 restores the spring 143 to its original position, causing the push block 142 to move to the right and reset. As the push block 142 moves left and right on the baffle plate 141, it pushes the mud on the baffle plate 141 to the left and right sides for the worker to collect. When the worker needs to paint other areas, they move the building's front lifting construction platform to the designated position and repeat the above operation to complete the painting operation again. When the worker no longer needs to use the building's front lifting construction platform, they press the main power switch again to de-energize the platform, and the pressure sensor 154 stops working.

[0038] It also includes a protective mechanism 16, which includes a protective frame 160, a fourth limiting rod 161, a connecting frame 162, and a second electric push rod 163. Three fourth limiting rods 161 are evenly spaced and slidably provided on the left and right sides of the top of the load-bearing plate 8. The protective frame 160 is provided between the tops of the fourth limiting rods 161. When the protective frame 160 moves upward, it can protect the worker. The connecting frame 162 is provided on the rear right side of the load-bearing plate 8. The second electric push rod 163 is provided in the middle of the connecting frame 162. The top of the telescopic rod of the second electric push rod 163 is connected to the protective frame 160.

[0039] When the load-bearing plate 8 rises to a suitable height, the worker can press the second switch 134 once. The second switch 134 sends a signal, and after receiving the signal, the control module controls the second electric push rod 163 to extend for 3 seconds. The extension rod of the second electric push rod 163 drives the protective frame 160 to move upward, thereby driving the fourth limit rod 161 to move upward. The fourth limit rod 161 acts as a guide. After 3 seconds, the control module controls the second electric push rod 163 to stop working. At this time, the protective frame 160 can play a certain protective role, preventing the worker from falling off the load-bearing plate 8. When the load-bearing plate 8 falls to a suitable height, the worker can press the second switch 134 again. The second switch 134 sends a signal, and after receiving the signal, the control module controls the second electric push rod 163 to shorten for 3 seconds. The extension rod of the second electric push rod 163 drives the protective frame 160 to move downward and reset, thereby driving the fourth limit rod 161 to move downward and reset. After 3 seconds, the control module controls the second electric push rod 163 to stop working.

[0040] It also includes a collection mechanism 17, which includes a first support block 170, a collection frame 171, a baffle 172, a push rod 173, a return spring 174, a fourth connecting block 175, a distance sensor 176, and an indicator light 177. The first limit rod 7 has a first support block 170 on its upper part, and a collection frame 171 is provided on the lower inner side of each first support block 170. The top inner side of each collection frame 171 contacts the baffle plate 141. When the mud on the baffle plate 141... When pushed out, the collection frame 171 can collect mud. Each collection frame 171 has a sliding baffle 172 at the bottom. Each baffle 172 has a push rod 173 at the bottom front side. Each push rod 173 has a return spring 174 between the upper rear side of the push rod 173 and the adjacent collection frame 171. The left collection frame 171 has a fourth connecting block 175 at the top front side. The fourth connecting block 175 has a distance sensor 176 at the rear side and an indicator light 177 at the front side.

[0041] It also includes a transmission mechanism 18, which includes a second support block 180, a connecting shaft 181, a third support block 182, a winding wheel 183, and a pull rope 184. The second support block 180 is located at the middle of the left side of the bottom of the baffle plate 141. The connecting shaft 181 is located at the middle of the bottom of the baffle plate 141. The third support block 182 is located at the middle of the front side of the bottom of the baffle plate 141. The winding wheel 183 is rotatably located at the lower part of the second support block 180, the middle of the connecting shaft 181, and the lower part of the third support block 182. There are three winding wheels 183. The pull rope 184 is located between the middle of the bottom of the lifting block 153 and the middle of the left side of the pushing block 142. The pull rope 184 passes around the three winding wheels 183 and passes through the top left side of the baffle plate 141.

[0042] When the lifting construction platform at the front of the building is powered on, the distance sensor 176 starts working. When the lifting block 153 moves downward, it drives the pull rope 184 to move. The winding wheel 183 acts as a guide, thereby driving the push block 142 to move to the left, compressing the pressure spring 143. When the lifting block 153 moves upward and resets, it releases the pull rope 184. At this time, the pressure spring 143 returns to its original state, driving the push block 142 to move to the right and reset, thereby resetting the pull rope 184. This pushes the mud on the baffle plate 141 to the left and right sides, causing the mud to fall into the collection frame 171. The baffle plate 172 will block the mud. This process repeats. When the distance sensor 176 senses that the distance between itself and the mud is less than the minimum preset value, the distance sensor 176 sends a signal. After receiving the signal, the control module controls... Indicator light 177 flashes to remind workers to promptly clean the mud from collection box 171. At this time, workers can push push rod 173 backward, compressing return spring 174, which in turn moves baffle 172 backward, allowing it to fall and be collected manually. Once all the mud has fallen, push rod 173 is released, return spring 174 to its original position, and push rod 173 moves forward to reset, which in turn moves baffle 172 forward to reset. At this time, distance sensor 176 detects that the distance between itself and baffle 172 is greater than the maximum preset value and sends a signal. Upon receiving the signal, the control module controls indicator light 177 to stop working. When the power to the lifting construction platform on the front of the building is lost, distance sensor 176 stops working.

[0043] It also includes a moving mechanism 19, which includes a mounting plate 190 and casters 191. The bottom left and right sides of the limit block 1 are provided with three mounting plates 190, and the bottom of each mounting plate 190 is provided with a rotatable caster 191.

[0044] With the help of the 191 casters, it is easier for workers to move the lifting construction platform at the front of the building. When workers need to paint other areas, they can simply ask a coworker to push the lifting construction platform at the front of the building. The 191 casters roll on the ground, eliminating the need for workers to climb up and down repeatedly, thus improving work efficiency.

[0045] like Figure 3 , Figure 14 and Figure 15As shown, it also includes a control box 131, a motor switch 132, a first switch 133, and a second switch 134. The control box 131 is located in the middle of the left side of the top of the load-bearing plate 8. The motor switch 132 is located on the front right side of the top of the control box 131. The first switch 133 is located in the middle of the right side of the top of the control box 131. The second switch 134 is located on the rear right side of the top of the control box 131. The control box 131 includes a switching power supply, a control module, and a power module. The switching power supply supplies power to the entire front lifting construction operation platform of the building. The power module is connected to the main power switch via a line. The control module and the power module are electrically connected. The control module is connected to a DS1302 clock circuit and a 24C02 circuit. The motor switch 132, the first switch 133, the second switch 134, the pressure sensor 154, the distance sensor 176, the indicator light 177, and the buzzer 155 are all electrically connected to the control module. The first electric push rod 152, the dual-axis reduction motor 3, and the second electric push rod 163 are all connected to the control module via external circuits.
