[0002] Building construction refers to houses or places where people conduct production, living, residence, or other activities, such as industrial buildings, civil buildings, and agricultural buildings. In the construction process of building construction, working at heights is an extremely common and indispensable part of the work. For example, exterior wall painting, door and window installation, and scaffolding erection all require work at height. To ensure that construction workers can safely and efficiently complete these high-altitude tasks, high-altitude work platforms have become essential equipment in the construction process.

[0003] Existing high-level work platforms are simple gantry structures that lack support and are prone to tipping over, causing accidents. Some platforms have fixed and non-adjustable support structures, which cannot be quickly retracted when the work location needs to be changed, making it difficult to move the platform conveniently. Utility Model Content

[0004] Therefore, it is necessary to provide a high-level operating platform for building construction to address the problem that some operating platforms have fixed and non-adjustable support structures, which cannot be quickly retracted when the work site needs to be moved, making it difficult to move the operating platform conveniently.

[0005] A high-level operation platform for building construction includes: a platform mechanism and a lifting mechanism, wherein the platform mechanism includes a worktable and several sets of support legs disposed on the lower surface of the worktable; The support mechanism includes casters, support pins, fixed sleeves, connecting rods, rotating sleeves, and a drive assembly for facilitating the retraction or release of the support pins. The casters are located at the bottom of the corresponding outriggers. Each set of outriggers has two sets of fixed sleeves on its side. The support pins are slidably disposed inside the corresponding fixed sleeves. One end of the support pins is connected to the connecting rod. The drive assembly includes an output gear, a large gear, a small gear, and an input module. The output gear is fixedly mounted on one side of the corresponding rotating sleeve. The large gear meshes with the small gear and is rotatably mounted on the side of the support leg away from the output gear.

[0006] In one embodiment, the input module includes a drive shaft, a ratchet, a limit wheel, a driven wheel, and a housing. The drive shaft is fixedly connected to the output gear rotation shaft, and a driven wheel is threadedly connected to one side of the drive shaft. The ratchet is rotatably disposed on the outer arc surface of the drive shaft.

[0007] In one embodiment, a friction plate is provided between the ratchet and the driven wheel, and a limit wheel is fixedly provided on the side of the driven wheel away from the friction plate, the limit wheel being disposed on the outer arc surface of the transmission shaft.

[0008] In one embodiment, the drive shaft is disposed inside the housing, and the housing is fixedly disposed on one side of the corresponding support leg. A drive wheel is rotatably disposed inside the housing. The drive wheel and the driven wheel are meshed with gear teeth on one side, and a handle is fixedly connected to one side of the drive wheel.

[0009] In one embodiment, a pawl is rotatably disposed inside the housing, and the pawl is located above the ratchet wheel, with a return spring disposed between the housing and the pawl.

[0010] In one embodiment, a connecting shaft is fixedly provided on the inner side of the output gear. The connecting shaft passes through the support leg and is fixedly connected to the corresponding large gear, and the radius of the large gear is larger than the radius of the small gear.

[0011] In one embodiment, the lifting mechanism includes a fence, a ladder, a winch, a fixed pulley, and a suspended platform. The fence is fixedly installed on the upper surface of the workbench, and the ladder is fixedly installed on one side of the workbench.

[0012] In one embodiment, the winch is disposed on the upper surface of the workbench, the fixed pulley is disposed on one side of the workbench, and a rope is disposed inside the winch, which passes through the fixed pulley and connects to the suspended platform. Beneficial effects

[0013] 1. The above-mentioned high-level operation platform for building construction uses a large gear and a small gear transmission to achieve force amplification and direction reversal, allowing the operator to operate the handle with less force. The input module drives the linkage to move, thereby controlling the raising and lowering of the support pins. When the workbench needs to work, the support pins are inserted into the ground, thereby enhancing the anti-tilt and anti-slip capabilities of the workbench. When the workbench moves, the support pins are in the retracted state, and the casters are on the ground, making it easy to push the workbench to move. This also facilitates the quick and easy retraction of the support pins, making the workbench portable and easy to move.

[0014] 2. The above-mentioned high-level operation platform for building construction achieves a one-way self-locking function through the cooperation of ratchet, pawl and friction plate. When the handle is turned clockwise, the support pin moves downward and inserts into the ground. At this time, the handle is released and automatically locked to prevent the support pin from retracting after being subjected to force. Turning the handle counterclockwise can unlock and retract the support pin, thereby ensuring the reliability of the work platform in the supported state and facilitating operation by the staff.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] The following is combined with Figures 1-5 This utility model describes a high-level operation platform for building construction.

[0020] In one embodiment, a high-level operation platform for building construction includes: a platform mechanism 100 and a lifting mechanism 300. The platform mechanism 100 includes a work platform 101 and several sets of outriggers 102 disposed on the lower surface of the work platform 101. The lifting mechanism 300 includes a railing 301, a ladder 302, a winch 303, a fixed pulley 304, and a suspended platform 305. The railing 301 is fixedly disposed on the upper surface of the work platform 101, and the ladder 302 is fixedly disposed on one side of the work platform 101. The winch 303 is disposed on the upper surface of the work platform 101, the fixed pulley 304 is disposed on one side of the work platform 101, and a rope is provided inside the winch 303 that passes through the fixed pulley 304 and connects to the suspended platform 305. In this embodiment, a workbench 101 is provided as a high-altitude work platform for construction workers, and outriggers 102 are provided on the lower surface to support the workbench 101; a fence 301 is provided to protect the workers working on the surface of the workbench 101, and a ladder 302 is provided to facilitate workers to go up and down; a winch 303, a fixed pulley 304, and a suspended basket 305 are used for vertical transportation of building materials, which effectively reduces the labor intensity of workers and improves construction efficiency.

[0021] like Figure 1 , Figure 3 and Figure 4 As shown, the support mechanism 200 includes casters 201, support pins 202, fixing sleeves 203, connecting rods 204, rotating sleeves 205, and a drive assembly for facilitating the retraction or release of the support pins 202. The casters 201 are located at the bottom of the corresponding support legs 102. Each set of support legs 102 has two sets of fixing sleeves 203 on its side. The support pins 202 are slidably disposed inside the corresponding fixing sleeves 203, and one end of the support pin 202 is connected to the connecting rod 204. The drive assembly includes... The system includes an output gear 206, a large gear 207, a small gear 208, and an input module 209. The output gear 206 is fixedly mounted on one side of the corresponding rotating sleeve 205. The large gear 207 meshes with the small gear 208 and is rotatably mounted on the side of the support leg 102 away from the output gear 206. A connecting shaft is fixedly mounted inside the output gear 206. The connecting shaft passes through the support leg 102 and is fixedly connected to the corresponding large gear 207. The radius of the large gear 207 is larger than the radius of the small gear 208. In this embodiment, the fixed sleeve 203 is arranged in an X shape, and the lower end of the support pin 202 inside the fixed sleeve 203 is conical, while the upper end is hinged to the connecting rod 204. The connecting rod 204 pushes the support pin 202 to move towards the ground and insert it into the ground. The power is finally transmitted to the rotating sleeve 205 through the output gear 206. The rotating sleeve 205 drives the connecting rod 204, which is hinged to it, to move, thereby pushing the support pin 202 downward from the fixed sleeve 203 and inserting it into the ground. The transmission method of using a large gear 207 to drive a small gear 208 has the effect of speed reduction and torque increase, making the process of pressing down the support pin 202 more effortless and easier to penetrate hard ground; when the workbench 101 needs to work, the support pin 202 is inserted into the ground, thereby enhancing the anti-tilt and anti-slip ability of the workbench 101; when the workbench 101 moves, the support pin 202 is in the retracted state, and the casters 201 are on the ground, thereby easily pushing the workbench 101 to move, and conveniently and quickly retracting the support pin 202, making it convenient for the workbench 101 to be moved easily.

[0022] like Figure 3 , Figure 4 and Figure 5 As shown, the input module 209 includes a drive shaft 210, a ratchet 211, a limit wheel 212, a driven wheel 213, and a housing 215. The drive shaft 210 is fixedly connected to the rotating shaft of the output gear 206. The driven wheel 213 is threadedly connected to one side of the drive shaft 210, and the ratchet 211 is rotatably disposed on the outer arc surface of the drive shaft 210. A friction plate 214 is disposed between the ratchet 211 and the driven wheel 213, and a limit wheel 212 is fixedly disposed on the side of the driven wheel 213 away from the friction plate 214. The drive shaft 210 is located on the outer arc surface of the drive shaft 210. The drive shaft 210 is located inside the housing 215, and the housing 215 is fixedly located on one side of the corresponding support leg 102. A drive wheel 216 is rotatably arranged inside the housing 215. The drive wheel 216 and the driven wheel 213 are meshed with gear teeth on one side. A handle 217 is fixedly connected to one side of the drive wheel 216. A pawl 218 is rotatably arranged inside the housing 215, and the pawl 218 is located above the ratchet 211. A return spring is arranged between the housing 215 and the pawl 218. In this embodiment, when the operator turns the handle 217 clockwise, the drive wheel 216 rotates, and the drive wheel 216 engages and drives the driven wheel 213 to rotate; the driven wheel 213 is threadedly connected to the side of the transmission shaft 210. At this time, the driven wheel 213 will move axially along the transmission shaft 210, thereby pressing the friction plate 214 and the ratchet 211; at this time, the pawl 218 is engaged in the groove of the ratchet 211 under the action of the return spring, preventing it from reversing, thereby transmitting the rotational torque to the transmission shaft 210 through the friction force generated by the friction plate 214, thereby driving the support pin 202 to move downward. After releasing the handle 217, the engagement of the pawl 218 and the ratchet 211 effectively prevents the drive shaft 210 from reversing due to the ground reaction force, thus ensuring the stability of the support. When it is necessary to retract the support pin 202, simply gently pry the pawl 218 to disengage it from the ratchet 211, and then turn the handle 217 counterclockwise. The driven wheel 213 moves in the opposite direction, thereby releasing the clamping of the friction plate 214 and the ratchet 211. At this time, the support pin 202 can be retracted with the assistance of external force, or the handle 217 can be turned counterclockwise to lift the support pin 202. The limit wheel 212 is used to limit the limit stroke of the driven wheel 213 to prevent it from coming off the outside of the drive shaft 210.

[0023] Working principle: When the workbench 101 moves, the support pin 202 is in the retracted state, and the platform is moved to the designated work position via the casters 201. When fixing is required, the operator cranks the handles 217 on each support leg 102, causing the drive wheel 216 and driven wheel 213 to rotate. The driven wheel 213 presses against the friction plate 214 and ratchet 211, causing the drive shaft 210 to rotate. The drive shaft 210 drives the pinion 208, gear 207, and output gear 206 to rotate. The output gear 206 drives the support pin 202 to insert into the ground via the rotating sleeve 205 and connecting rod 204, providing support. The pawl 218 prevents the ratchet from being rattled. When wheel 211 reverses, because ratchet 211 is connected to driven wheel 213 and drive shaft 210, it prevents support pin 202 from loosening. Reversing handle 217 decouples ratchet 211 from driven wheel 213 and drive shaft 210, allowing it to continue reversing. Driven wheel 213 presses against limit wheel 212, causing drive shaft 210 to reverse. Through this transmission and self-locking mechanism, support pin 202 is inserted into the ground, forming stable support. At this point, caster wheel 201 may be slightly off the ground or its pressure on the ground may decrease. The integrated high-altitude lifting function can operate independently for lifting materials. After operation, first release the self-locking of pawl 218, then reverse handle 217 to retract support pin 202, restoring the movable state.

[0024] It should be noted that the winch 303 and other components mentioned above are all devices with relatively mature existing technologies. The specific model can be selected according to actual needs. The winch 303 can be powered by an internal power supply or by AC power. The specific power supply method should be selected according to the situation, which will not be elaborated here.

[0025] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
