Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a height-adjustable indoor building platform. Background Technology

[0002] Interior decoration is an indispensable part of people's lives. Its functions include protecting the main structure of a building, improving its performance, and beautifying it. When workers are decorating the interior and exterior, they often need to use construction platforms to facilitate work at higher levels. Construction platforms are used to facilitate construction work, providing workers with a platform for working at heights and ensuring installation quality and safety.

[0003] Currently, workers can use scaffolding to complete high-altitude and climbing operations. Foldable scaffolding is also available on the market, generally used for home renovations. In addition, there are some construction platforms with adjustable height. However, some shortcomings still exist: when installing long pipes, boards, or lintels used on doors and windows, workers below need to pass these materials upwards. Because long pipes are heavy, manual passing is difficult. While existing liftable construction platforms can adjust the height, they are not suitable for limiting and transporting long pipes. Ropes and other auxiliary tools are generally needed for securing them. If the pipes are not limited or the ropes are not securely fastened during transport, they may fall, causing personal injury and damage to property. Furthermore, piled pipes or other building materials may roll or shift during upward transport, requiring workers to assist in securing them for stable upward transport, which increases the labor intensity of workers.

[0004] In view of this situation, the present invention provides an indoor construction platform that limits the length of pipes or plates to prevent them from rolling or deviating during upward transportation, and is height-adjustable without the need for worker assistance. The purpose is to reduce the labor intensity of workers and speed up the construction progress.

[0005] In conclusion, it is necessary to design a height-adjustable indoor building platform to solve this problem. Summary of the Invention

[0006] The purpose of this invention is to provide a height-adjustable indoor construction platform to solve the problem mentioned in the background art: although existing liftable construction platforms can adjust the height of the construction platform, they cannot limit the movement of long pipes, which makes the pipes prone to rolling or deviating when transported upwards.

The outer wall of the first driven shaft is provided with a second synchronous belt, and the first driven shaft is connected to the second driven shaft through the second synchronous belt. The outer walls of the drive shaft and the second driven shaft are fixedly connected to a connecting rod, which is rotatably connected to the inside of the slide.

[0011] Furthermore, the number of limiting mechanisms is four, with each pair of limiting mechanisms forming a group. The two groups of limiting mechanisms are located inside the two extended platforms respectively. One of the clamps is equipped with a reinforcement mechanism, and the number of reinforcement mechanisms is four.

[0012] Furthermore, the reinforcement mechanism includes a suction cup, which is fixedly connected to the inside of one of the clamps. The clamp containing the suction cup is located on top of the fixed base. An electric telescopic rod is fixedly installed inside the base. A cylinder is fixedly connected inside the base. A piston is slidably connected inside the cylinder. The telescopic end of the electric telescopic rod is fixedly connected to the piston. An air pipe is inserted inside the cylinder. The other end of the air pipe is fixedly connected to the suction cup.

[0013] Furthermore, the lifting mechanism includes two base shells, which are fixedly connected to both sides of the main board.

A protective shell is fixedly connected between the two base shells, and the timing belt is located inside the protective shell. The outer walls of the drive screw and the driven screw are threadedly connected to the building platform.

[0016] Furthermore, four casters are fixedly mounted in a rectangular array at the bottom of the motherboard, and all four casters have a self-locking function.

[0017] Furthermore, a support assembly is fixedly installed on one side of each of the four mounting brackets. The support assembly includes a leg and a housing.

[0018] Furthermore, two protective plates are fixedly connected to the top of the building platform, a storage box is fixedly connected to the top of the building platform, and limit plates are fixedly connected to both sides of the building platform, with the extension platform located above the limit plates.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. The height-adjustable indoor construction platform of the present invention uses a limiting mechanism to fix longer pipes. Compared with existing lifting construction platforms, this height-adjustable indoor construction platform can prevent the pipes from rolling or shifting during upward transportation. In addition, the lifting mechanism realizes automated upward transportation of pipes, thereby reducing the labor intensity of workers and speeding up the construction progress. The combination of the flipping mechanism and the limiting mechanism not only fixes the pipes, but also forms a guardrail on the extended platform to protect workers standing on it during construction, thereby improving the safety of the height-adjustable indoor construction platform. Furthermore, the extended platform is not limited to carrying pipes; when necessary, it can also place other materials or items during construction to serve as an extension platform for the construction platform, increasing the workers' working space.

[0021] 2. The height-adjustable indoor building platform of the present invention utilizes a reinforcement mechanism to perform secondary fixation on longer pipes, thereby increasing the stability of the pipes during transportation. When the limiting mechanism is released from fixing the pipes, the reinforcement mechanism still fixes the pipes, thus preventing pipe displacement. In addition, the clamps are fixedly connected to the fixed seat and the moving seat by bolts, so they can be replaced according to the shape of the pipes or other building materials required for actual construction, thus improving the applicability of the height-adjustable indoor building platform.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0034] Obviously, many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0035] Please see Figure 1-10 The present invention provides a height-adjustable indoor building platform: including a main board 1, a lifting mechanism 2 and a building platform 3 are arranged above the main board 1, an extension platform 7 is hinged to both sides of the building platform 3, a limiting mechanism 8 for limiting the pipe material is arranged inside the extension platform 7, and a flipping mechanism 15 is arranged at the bottom of the building platform 3.

[0036] The limiting mechanism 8 includes a base 801, which is fixedly connected to the interior of the extended platform 7. A slide rod 807, a first slide shell 811, and a second slide shell 812 are slidably connected inside the base 801. A motion seat 804 is fixedly connected to the top of both the first slide shell 811 and the second slide shell 812, and the motion seat 804 is slidably connected to the base 801. A fixed seat 803 is fixedly connected inside the base 801. Clamps 805 are bolted to the tops of the fixed seat 803 and the motion seat 804 respectively. A first spring 802 is fixedly installed inside the base 801. The other end is fixedly connected to the motion seat 804. Sliding shell 1 811 and sliding shell 2 812 are slidably connected to the sliding rod 807 respectively. A limit pin 806 is slidably connected inside the base 801. Sliding shell 1 811 and sliding shell 2 812 are fixed to the sliding rod 807 respectively by the limit pin 806. A sliding block 808 is slidably connected to the bottom of the base 801. A spring 2 809 is fixedly installed inside the sliding block 808. A sliding plate 810 is slidably connected inside the sliding block 808. The sliding plate 810 is fixedly connected to the spring 2 809. The spring 2 809 has a greater compressive strength than the spring 1 802. When transporting a longer pipe upwards, the pipe is first placed in clamp 805. During this process, clamp 805 on the moving seat 804 can be pushed to compress spring 802, adjusting the distance between the two clamps 805 to ensure the pipe is properly positioned. The pipe can then be transported via lifting mechanism 2. Since spring 809 has a greater compressive strength than spring 802, without spring 809 being compressed, the moving seat 804 is first driven by sliding shells 811 and 812, thus clamping and fixing the pipe. After the pipe is fixed, if the sliding seat... 808 continues to move. At this time, the slide plate 810 will compress the second spring 809 to ensure that the slide plate 810 will not interfere with the slide rod 807. It also accommodates pipes of different diameters, increasing the practicality of this height-adjustable indoor building platform. After the pipes are transported to the construction site, when it is necessary to remove the pipes, the limit pin 806 needs to be pulled out from the inside of the base 801 to release the fixation between the first slide shell 811, the second slide shell 812, and the slide rod 807. At this time, the spring 802 will reset and drive the motion seat 804 to release the fixation of the pipes, and then the pipes can be removed.

[0037] The tilting mechanism 15 includes a second motor 151, which is fixed to the bottom of the building platform 3. One end of the output shaft of the second motor 151 is fixedly connected to a drive shaft 152, which is rotatably connected to the bottom of the building platform 3. A driven shaft 153 and a driven shaft 158 ​​are rotatably connected to the bottom of the building platform 3. One end of the drive shaft 152 and the driven shaft 153 are respectively fixedly connected to a drive gear 155 and a driven shaft 158. The drive gear 155 and the driven gear 156 mesh with each other. A synchronous belt 154 is provided on the outer wall of the driven shaft 153, which is connected to the driven shaft 158 ​​via the synchronous belt 154. A connecting rod 157 is fixedly connected to the outer walls of the drive shaft 152 and the driven shaft 158. The 57 is rotatably connected inside the slide 808. There are four limiting mechanisms 8, arranged in pairs. Two sets of limiting mechanisms 8 are located inside the two extended platforms 7. One of the clamps 805 has a reinforcing mechanism 14 inside, and there are four reinforcing mechanisms 14. The motor 151 drives the drive shaft 152 to rotate. The meshing between the drive gear 155 and the driven gear 156 drives the driven shaft 153 to rotate. Then, the synchronous belt 154 causes the driven shaft 158 ​​to rotate, which in turn causes the connecting rod 157 to move, driving the two extended platforms 7 to rotate simultaneously (towards or in opposite directions). When the extended platforms 7 move, the connecting rod 157 is rotatably connected inside the slide 808. The sliding block 808 can slide at the bottom of the base 801, causing the sliding plate 810 inside the base 801 to contact the sliding rod 807. After the extension platform 7 is flipped, it can form a guardrail to protect the workers. In addition, it will also move the pipe. After the extension platform 7 has finished moving, the pipe is clamped by the clamp 805 on the moving seat 804 and lifted by the clamp 805 on the fixed seat 803, which also facilitates the subsequent handling of the pipe by the construction personnel. The reinforcement mechanism 14 includes a suction cup 141, which is fixedly connected to the inside of one of the clamps 805. The clamp 805 where the suction cup 141 is located is located on the top of the fixed seat 803. An electric telescopic rod 145 is fixedly installed inside the base 801. A cylinder 143 is fixedly connected inside the fixture 805, and a piston 144 is slidably connected inside the cylinder 143. The telescopic end of an electric telescopic rod 145 is fixedly connected to the piston 144. An air tube 142 is inserted inside the cylinder 143, and the other end of the air tube 142 is fixedly connected to a suction cup 141. After the tube is placed into the fixture 805, the tube will come into contact with the suction cup 141 under the clamping of the fixture 805 and will be adsorbed by the suction cup 141 under the clamping of the fixture 805, thereby increasing the stability of the tube during transportation. When the suction cup 141 is released from adsorption of the tube, the piston 144 can be slid inside the cylinder 143 by controlling the electric telescopic rod 145, so that gas is injected from the air tube 142 into the inner cavity of the suction cup 141.This releases the suction cup 141 from the tube material, allowing it to be removed.

[0038] The lifting mechanism 2 includes two base shells 205, which are fixedly connected to both sides of the main board 1. One base shell 205 houses a motor 201, and one end of the output shaft of the motor 201 is fixedly connected to a drive screw 202. The other base shell 205 houses a driven screw 203, and the outer wall of the drive screw 202 is provided with a timing belt 204. The drive screw 202 is connected to the driven screw 203 via the timing belt 204. The two base shells 205 are fixedly connected. There is a protective shell 13, and a timing belt 204 is located inside the protective shell 13. The outer walls of the driving screw 202 and the driven screw 203 are threadedly connected to the building platform 3. Two guide rods are fixedly connected to the top of each of the two base shells 205. The building platform 3 is slidably connected to the four guide rods. The driving screw 202 is driven to rotate by the motor 201, and the driven screw 203 is rotated synchronously by the timing belt 204. This causes the threaded building platform 3 to move up and down along the guide rods, thereby adjusting the height of the building platform 3 to meet the construction requirements.

[0039] Four mounting brackets 4 are fixedly connected to the top of the main board 1. Two supports 5 are fixedly connected to the top of each of the two base shells 205. The four mounting brackets 4 are fixedly connected to the four supports 5 respectively. The four supports 5 are in pairs. A top plate 9 is fixedly connected to one side of each pair of supports 5. The bottom of each of the two top plates 9 is fixedly connected to a guide rod. The mounting brackets 4 and supports 5 are used to support the height-adjustable indoor building platform. The guide rod can guide the building platform 3. Electric telescopic rods 16 are fixedly installed inside each of the two base shells 205. Support frames 12 are fixedly connected to the telescopic ends of the two electric telescopic rods 16. Anti-slip pads are fixedly connected to the bottom of the two support frames 12. Four casters are fixedly installed in a rectangular array at the bottom of the main board 1. The four casters are all equipped with a self-locking function. After the height-adjustable indoor building platform is moved to the construction position, the casters are locked first. Then, by telescopically extending the electric telescopic rods 16, the support frames 12 can be pushed to contact the ground. The height-adjustable indoor building platform is supported to increase its stability. Support components 17 are fixedly installed on one side of each of the four mounting brackets 4. Each support component 17 includes a leg and a housing. The housing is fixedly connected to the mounting bracket 4. One end of the leg is located inside the housing and is rotatably connected. The leg is fixedly connected to the housing by a bolt assembly. The support components 17 further fix and support the height-adjustable indoor building platform. Two protective plates 6 are fixedly connected to the top of the building platform 3. A storage box 10 is fixedly connected to the top of the building platform 3. The storage box 10 can store construction materials, such as cement slurry. The protective plates 6 mainly prevent materials from contacting the active screw 202 and the driven screw 203. Limiting plates 11 are fixedly connected to both sides of the building platform 3. The extension platform 7 is located above the limiting plates 11. The presence of the limiting plates 11 can support the extension platform 7, thereby increasing the stability of the extension platform 7.

[0040] Specific working method: When in use, this height-adjustable indoor construction platform provides workers with a platform for working at height and the ability to climb. Specifically, the motor 201 drives the active lead screw 202 to rotate, and the synchronous belt 204 makes the driven lead screw 203 rotate synchronously, so that the threaded construction platform 3 moves up and down along the guide rod, thereby adjusting the height of the construction platform 3 to meet the construction needs.

[0041] During construction, when it is necessary to transport a long pipe upwards, the pipe is first placed in the clamp 805. During this process, the clamp 805 on the moving seat 804 can be pushed to compress the spring 802 to adjust the distance between the two clamps 805, ensuring that the pipe is placed in place. Then, the pipe can be transported by the lifting mechanism 2. In addition, the drive shaft 152 can be driven to rotate by the motor 151, and the driven shaft 153 can be driven to rotate by the meshing between the drive gear 155 and the driven gear 156. Then, the synchronous belt 1... 54, causing the driven shaft 158 ​​to rotate, which in turn causes the connecting rod 157 to move, driving the two extended platforms 7 to rotate simultaneously (moving towards or in opposite directions). While the extended platforms 7 are moving, the connecting rod 157 is rotatably connected inside the slide 808, thus causing the slide 808 to slide at the bottom of the base 801. This causes the sliding plate 810 inside the base 801 to contact the sliding rod 807. Since the compressive strength of the second spring 809 is greater than that of the first spring 802, the second spring 809, without being compressed, moves the seat... 804 is first driven by sliding shell 811 and sliding shell 812 to clamp and fix the pipe. After the pipe is fixed, the slide block 808 continues to move. At this time, the sliding plate 810 will compress the spring 809 to ensure that the sliding plate 810 will not interfere with the sliding rod 807. It also accommodates pipes of different diameters, increasing the practicality of this height-adjustable indoor building platform. During this process, the pipe will come into contact with the suction cup 141 and be attracted by the suction cup 141 under the support of the clamp 805, thereby increasing the efficiency of the pipe during transportation. The extended platform 7, when flipped, forms a protective railing to protect workers. It also moves the pipes along with it. After the extended platform 7 has finished moving, the pipes are held by the clamps 805 on the moving seat 804 and lifted by the clamps 805 on the fixed seat 803, which makes it easier for construction workers to retrieve the pipes. In addition, the extended platform 7 is not only used for carrying pipes, but can also be used to place other materials or items, serving as an extension platform of the construction platform 3 to increase the workers' working space.

[0042] After the pipe is transported to the construction site, when it is necessary to remove the pipe, the limiting pin 806 needs to be pulled out from the inside of the base 801 to release the fixation between the sliding shell 811, the sliding shell 812, and the sliding rod 807. At this time, the spring 802 will reset and drive the moving seat 804 to release the fixation of the pipe. The pipe will continue to be fixed by the suction cup 141 to prevent the pipe from shifting. After the worker comes into contact with the pipe, the piston 144 can slide inside the cylinder 143 by controlling the electric telescopic rod 145, and the gas will be injected from the air pipe 142 into the inner cavity of the suction cup 141, thereby releasing the suction cup 141 from the pipe and removing the pipe. In addition, the clamp 805 is fixedly connected to the fixed seat 803 and the moving seat 804 by bolts. Therefore, it can be replaced according to the pipe or plate material used in the actual construction, which improves the applicability of this height-adjustable indoor building platform.
