Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a multifunctional scaffold. Background Technology

[0002] Scaffolding is a working platform erected to ensure the smooth progress of construction. Many cities now require renovation and upgrading, and scaffolding is often used as a working platform during the construction of building exteriors. Therefore, scaffolding operations are not limited to construction sites, but may also be set up on streets with high pedestrian traffic and near shops. As a result, scaffolding must not only consider its own stability, but also maximize its functionality to avoid impacting the surrounding environment and pedestrians. Thus, a multi-functional scaffolding is needed.

[0003] Existing scaffolding generally consists of components such as legs, a top plate, ladders, and guardrails. Some sections of the scaffolding structure are equipped with reinforcing ribs for support and increased strength. To improve the functionality of the scaffolding, guardrails are usually installed on the legs to better protect the surrounding environment, thus providing a safe protection zone for the scaffolding's erection location. Alternatively, protective plates can be installed at the legs. For example, Chinese patent CN218346714U (A Multifunctional Scaffold) designs the protective plates at the bottom of the legs into different forms such as tables and chairs for convenient use.

[0004] However, in actual use, the aforementioned equipment requires personnel to go up and down the scaffold, and also requires the continuous use of tools and materials. In particular, scaffolding used for the decoration and renovation of the exterior walls of buildings in construction projects requires the cooperation of workers on the scaffold and workers on the ground. Workers on the scaffold must consider their own walking and working space as well as the placement and retrieval of materials, which brings great inconvenience to the workers and affects the effectiveness of the scaffolding. In view of this, we propose a multi-functional scaffolding. Summary of the Invention

[0005] The purpose of this invention is to provide a multifunctional scaffolding to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a multifunctional scaffold, including legs, a working platform fixedly installed on the top side wall of each leg, a guardrail detachably connected to the side wall of each leg, and an extension component provided at the end of the working platform, the extension component comprising:

[0007] A connecting column is fixedly installed at the end of the working platform, and a ladder is movably connected to the connecting column through a connecting block sleeved on its arc-shaped outer wall.

[0008] Mounting base, the mounting base is fixedly installed on the side wall of the ladder, the mounting base is slidably connected to the inner wall of the mounting base, the bottom inner wall of the mounting slider is hinged to the top end of the connecting rod, the bottom end of the connecting rod is hinged to the middle part of the support rod, and the side wall of the support leg is fixedly installed with a receiving block.

[0009] The telescopic cylinder has one end fixedly connected to the end of the mounting slider, and the other end of the telescopic cylinder is fixedly connected to a threaded slider. A locking spring is provided between the mounting slider and the threaded slider. An adjusting bolt is rotatably installed on the outer wall of the end of the mounting base, and an adjusting screw is fixedly installed on the side wall of the adjusting bolt.

[0010] Preferably, the number of support legs is set to two sets, and the two sets of support legs are respectively set at both ends of the working platform. The support legs are concave to ensure that the working platform is located at the center of the support legs, so that the working platform can obtain a more stable support effect.

[0011] Preferably, the top of the ladder is provided with a pin, and the inner wall of the working plate is provided with a hole that matches the pin, so that when the ladder rotates to a state that is parallel to the working plate, the pin is precisely aligned with the hole on the working plate.

[0012] Preferably, the mounting slider is configured as a square block with a groove at the bottom, and the width of the groove is adapted to the width of the connecting rod. In addition, the inner wall of the mounting base has a square groove for the mounting slider to slide, thereby guiding and restricting the movement of the mounting slider. The lower surface of the mounting base has a storage groove with a size adapted to the width of the support rod, and the top end of the support rod is hinged to the inner wall of the mounting base.

[0013] Preferably, the bottom end of the support rod is arc-shaped, and the outer wall of the receiving block is provided with a concave contact groove, and the outer surface of the contact groove is covered with a rubber pad, so that when the bottom end of the support rod is inserted into the inside of the contact groove, the stability between the receiving block and the support rod is more stable due to the downward pressure of the support rod.

[0014] Preferably, the telescopic cylinder is hollow inside, and the diameter of the internal cavity of the telescopic cylinder is larger than the outer diameter of the adjusting screw, so that there is no motion interference between the adjusting screw and the telescopic cylinder, ensuring the relative stability of the device during operation.

[0015] Preferably, the inner wall of the ladder is slidably connected to a drawer ladder, the top of the drawer ladder is through a fixed shaft, and the fixed shaft is rotatably connected to the drawer ladder. A spiral spring is fixedly connected to the arc-shaped outer wall of the fixed shaft.

[0016] Preferably, the inner wall of the ladder has a receiving groove of a size that matches the drawer ladder, and the inner surface of the receiving groove has a straight groove of a size that matches the fixed axis, thereby better restricting the drawer ladder to only slide within the inner wall of the ladder.

[0017] Preferably, a take-up roller is rotatably mounted on the inner surface of the top of the ladder, and a connecting cloth is wound around the arc-shaped outer wall of the take-up roller. A receiving roller is rotatably mounted on the inner surface of the drawer ladder. The receiving roller is made of rubber material to provide buffering and support for the downward pressure transmitted on the connecting cloth. Several protrusions are provided on the arc-shaped outer wall of the receiving roller.

[0018] Preferably, the end of the connecting cloth is provided with a fixing buckle so that the connecting cloth can be fixed to the inner surface of the bottom of the drawer after it extends out. The width of the connecting cloth is adapted to the inner width of the ladder, so as to provide support for the connecting cloth in conjunction with the crossbar provided on the inner surface of the ladder.

[0019] Compared with the prior art, the present invention provides a multifunctional scaffolding with the following advantages:

[0020] 1. This multi-functional scaffold, after the ladder rotates to be parallel with the working platform, pulls out the support rod and inserts its bottom end into the contact groove opened on the receiving block, so that the support rod, ladder and legs form a stable triangle, so that the support rod and the receiving block can provide support to keep the ladder in a horizontal state, thereby allowing the ladder to support more materials after rotating to a horizontal state, making it convenient for workers to use.

[0021] 2. This multi-functional scaffolding features a fixed shaft and a spiral spring at the top of the pull-out ladder. This allows the bottom of the ladder to rest on the ground after it is pulled out. Combined with the elasticity of the spiral spring, the ladder can achieve stable support even at the end away from the working platform. This not only ensures the stability of the expanded working area but also further enhances the anti-sway effect of the entire scaffolding, ensuring the safety of workers.

[0022] 3. This multi-functional scaffolding features a take-up roller with a connecting cloth wrapped around it at the top of the ladder. Combined with a fixing buckle at the end of the connecting cloth, the fully extended connecting cloth forms a channel that covers both the ladder and the pull-out ladder. This allows workers to transport tools or materials down through this channel. Furthermore, the arc-shaped outer wall of the receiving roller has several protrusions to slow down materials or tools sliding down the connecting cloth, preventing them from falling and breaking, and avoiding accidents caused by materials or tools being thrown down.

[0032] like Figure 1-8 As shown, the present invention provides a technical solution: a multifunctional scaffold, including a support leg 1, a working platform 2 fixedly installed on the top side wall of the support leg 1, a guardrail 3 detachably connected to the side wall of the support leg 1, an extension component provided at the end of the working platform 2, the extension component including a connecting column 4, the connecting column 4 fixedly installed at the end of the working platform 2, the connecting column 4 being movably connected to a ladder 5 through a connecting block sleeved on its arc-shaped outer wall, a mounting base 6 fixedly installed on the side wall of the ladder 5, the inner wall of the mounting base 6 being slidably connected to... There is a mounting slider 7, the bottom inner wall of the mounting slider 7 is hinged to the top of the connecting rod 8, the bottom end of the connecting rod 8 is hinged to the middle of the support rod 9, the side wall of the support leg 1 is fixedly installed with a receiving block 10, the end of the mounting slider 7 is fixedly connected to one end of the telescopic cylinder 11, the other end of the telescopic cylinder 11 is fixedly connected to the threaded slider 12, a locking spring 13 is provided between the mounting slider 7 and the threaded slider 12, the end outer wall of the mounting base 6 is rotatably installed with an adjusting bolt 14, and the side wall of the adjusting bolt 14 is fixedly installed with an adjusting screw 15.

[0033] In one embodiment of the present invention, two sets of support legs 1 are provided, and the two sets of support legs 1 are respectively located at both ends of the working platform 2. The support legs 1 are concave to ensure that the working platform 2 is centered on the support legs 1, thereby providing a more stable support effect for the working platform 2. At the same time, the guardrail 3 is connected to the side wall of the support legs 1 by bolts, and the height of the guardrail 3 on the support legs 1 can be adjusted according to the relevant needs of the construction operation, thereby changing the protection height and range of the guardrail 3 to facilitate the work of construction workers on the working platform 2 and improve the flexible application effect of the scaffolding. Furthermore, the connecting column 4 is parallel to the working platform 2. At the same time, the lower surface of the ladder 5 is provided with two sets of connecting blocks, and the two sets of connecting blocks are sleeved on the outer wall of the connecting column 4, so that the ladder 5 can rotate around the connecting column 4 as the rotation axis in coordination with the connecting blocks. Specifically, the top of the ladder 5 is provided with a pin, and the inner wall of the working plate 2 is provided with a hole that matches the pin. So that when the ladder 5 rotates to a state that is parallel to the working plate 2, the pin is exactly aligned with the hole on the working plate 2, so that the ladder 5 and the working plate 2 are kept in a relatively fixed state, so that the workers can place the materials and tools required for the work on the ladder 5, expand the space of the working plate 2, and make it convenient for the workers to use.

[0034] In an embodiment of the present invention, two mounting bases 6 are provided, and the two mounting bases 6 are respectively arranged on the left and right sides of the ladder 5. Meanwhile, the mounting slider 7 is configured as a square block with a groove on its lower surface, and the width of the groove is adapted to the width of the connecting rod 8. Furthermore, the inner wall of the mounting base 6 has a square groove for the mounting slider 7 to slide, thereby guiding and restricting the movement of the mounting slider 7. Specifically, the lower surface of the mounting base 6 has a storage groove whose size is adapted to the width of the support rod 9, and the top end of the support rod 9 is hinged to the inner wall of the mounting base 6. Further, the bottom end of the support rod 9 is... The support block 10 is shaped like an arc and has a concave contact groove on its outer wall. The outer surface of the contact groove is covered with a rubber pad. When the bottom end of the support rod 9 is inserted into the contact groove, the stability between the support block 10 and the support rod 9 is enhanced by the downward pressure of the support rod 9. At the same time, the support rod 9, the ladder 5, and the support leg 1 form a stable triangle. This allows the support rod 9 and the support block 10 to support the ladder 5 in a horizontal position, enabling the ladder 5 to support more materials after rotating to a horizontal position, making it more convenient for workers to use.

[0035] In an embodiment of the present invention, the locking spring 13 is sleeved on the outside of the telescopic cylinder 11, and the inside of the telescopic cylinder 11 is hollow. Specifically, the diameter of the internal cavity of the telescopic cylinder 11 is larger than the outer diameter of the adjusting screw 15, so that there is no movement interference between the adjusting screw 15 and the telescopic cylinder 11, ensuring the relative stability of the device during operation. At the same time, the adjusting screw 15 is threadedly connected to the threaded slider 12, and the shape of the threaded slider 12 is set to be the same as the shape of the mounting slider 7, so that the movement of the threaded slider 12 can be guided and restricted. Specifically, when the adjusting bolt 14 is rotated, it cooperates with the rotation of the adjusting screw 15, so that the threaded slider 12 can only move horizontally along the inner wall of the mounting base 6, and will not rotate with the rotation of the adjusting screw 15. Then, the position of the threaded slider 12 can be changed by rotating the adjusting bolt 14, thereby changing the contraction state of the locking spring 13, so that it drives the mounting slider 7 and the connecting rod 8 to keep the support rod 9 in a taut state, thereby improving the stability of the ladder 5 when it is unfolded to a parallel state and improving the work efficiency of the construction personnel.

[0036] In addition, a drawer ladder 16 is slidably connected to the inner wall of the ladder 5. A fixed shaft 20 passes through the top of the drawer ladder 16 and is rotatably connected to the drawer ladder 16. A spiral spring 21 is fixedly connected to the arc-shaped outer wall of the fixed shaft 20. Specifically, a receiving groove of a size adapted to the drawer ladder 16 is opened on the inner wall of the ladder 5, and a straight groove of a size matching the fixed shaft 20 is opened on the inner surface of the receiving groove. This better restricts the drawer ladder 16 to only slide within the inner wall of the ladder 5. When the top of the drawer ladder 16 has completely slid to the end of the ladder 5, the straight groove restricts the fixed shaft 20, preventing the drawer ladder 16 from completely detaching from the ladder 5. During this process, the straight groove restricts the fixed shaft 20, preventing the drawer ladder 16 from being completely pulled out. The ladder 16 rotates around the fixed shaft 20. A circular groove with a diameter larger than the outer diameter of the spiral spring 21 is provided on the top side wall of the ladder 16. Specifically, the other end of the spiral spring 21 is fixedly connected to the bottom inner surface of this circular groove. The elastic force of the spiral spring 21 always acts on the ladder 16, ensuring it always has a clockwise rotational tendency around the fixed shaft 20. This allows the bottom of the ladder 16 to rest on the ground after it is pulled out. Combined with the elastic force of the spiral spring 21, the ladder 5 can achieve stable support even at the end away from the working platform 2. This not only ensures the stability of the expanded working area but also further enhances the anti-sway effect of the entire scaffolding, ensuring the safety of the workers.

[0037] In an embodiment of the present invention, a take-up roller 18 is rotatably mounted on the inner surface of the top of the ladder 5, and a connecting cloth 19 is wound around the arc-shaped outer wall of the take-up roller 18. A receiving roller 17 is rotatably mounted on the inner surface of the drawer 16. Specifically, a fixing buckle is provided at the tail end of the connecting cloth 19 so that the connecting cloth 19 can be fixed on the inner surface of the bottom end of the drawer 16 after being stretched out. The width of the connecting cloth 19 is adapted to the internal width of the ladder 5, thereby cooperating with the crossbar provided on the inner surface of the ladder 5 to provide support for the connecting cloth 19. Furthermore, the receiving roller 17 adopts... The rubber rollers provide cushioning and support for the downward pressure transmitted on the connecting cloth 19. The fully extended connecting cloth 19 forms a channel that covers the ladder 5 and the pull-out ladder 16, allowing workers to transport tools or materials down through this channel. The arc-shaped outer wall of the receiving roller 17 is provided with several protrusions to slow down the materials or tools sliding down the connecting cloth 19, preventing them from falling and breaking, and avoiding accidents caused by materials or tools being thrown down directly.

[0038] In this invention, during use, the user first climbs onto the working platform 2 via the ladder 5. Then, another worker on the ground rotates the ladder 5 upwards, making it rotate around the connecting column 4 as its axis of rotation, until the ladder 5 and the working platform 2 are parallel. The pin at the top of the ladder 5 is then aligned with the hole on the working platform 2 and inserted, maintaining a relatively fixed position between the ladder 5 and the working platform 2. At this point, the bottom end of the support rod 9 is inserted into the contact groove on the receiving block 10, forming a stable triangle between the support rod 9, the ladder 5, and the support leg 1. By rotating the adjusting bolt 14, the position of the threaded slider 12 is changed, altering the contraction state of the locking spring 13. This causes the mounting slider 7 and the connecting rod 8 to keep the support rod 9 taut. Thus, the support rod 9, in conjunction with the receiving block 10, provides support to keep the ladder 5 horizontal, allowing the ladder 5 to support more materials after rotating to a horizontal position, facilitating worker use. In one step, by setting a fixed shaft 20 and a spiral spring 21 at the top of the pull-out ladder 16, the bottom of the pull-out ladder 16 is supported on the ground after it is pulled out. With the elasticity of the spiral spring 21, the end of the ladder 5 away from the working platform 2 can also obtain a stable support effect. This not only ensures the stability of the expanded working area, but also further improves the anti-sway effect of the entire scaffolding, ensuring the safety of the workers. Furthermore, by setting a take-up roller 18 with a connecting cloth 19 wrapped around it at the top of the ladder 5, and with the fixing buckle set at the end of the connecting cloth 19, the fully pulled-out connecting cloth 19 forms a channel that covers the ladder 5 and the pull-out ladder 16. When workers need to transport some tools or materials down, they can transport them down through this channel. In addition, the arc-shaped outer wall of the receiving roller 17 is provided with several protrusions, which facilitates the deceleration of materials or tools sliding down the connecting cloth 19, preventing them from falling and breaking, and preventing materials or tools from being thrown down and causing accidents.

[0039] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
