Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a self-climbing power system for an integral lifting steel platform. Background Technology

[0002] In the concrete pouring construction of the core tube of high-rise and super high-rise buildings, the steel platform self-climbing power device is a key piece of equipment used to lift the steel platform in building construction. It has attracted much attention due to its excellent performance and many advantages, which improves construction efficiency, shortens the construction cycle, and is simple and convenient to operate, reducing construction difficulty and labor costs.

[0003] A search revealed Chinese Patent Publication No. CN213710309U, which discloses a steel platform device for lifting elevator shafts in construction. The device comprises large wheels on the left and right inner walls of the elevator shaft body, which are movably connected to small wheels via ropes. A steel platform is fixedly mounted at the bottom of the small wheels, a hook ring is fixedly mounted at the top of the steel platform, and a support rod is fixedly mounted at the bottom of the steel platform. A movable shaft is movably mounted at the bottom of the support rod, and a movable arm is movably connected to the right end of the movable shaft. This steel platform device for lifting elevator shafts in construction is detachable and reusable. It is environmentally friendly, improves construction safety and progress, and saves construction costs. It can be lifted layer by layer as the main structure rises. It is easy to install and operate, quick to hoist, and accelerates construction speed. Safe operation is guaranteed. Different operating platform lifting frames can be made according to the size of the elevator shaft and the floor height, making it highly adaptable. However, in actual use, this device controls the lifting of the platform through wheels and ropes. But when the power unit fails or encounters an emergency, there is a lack of effective safety protection mechanism, which may lead to accidents such as the steel platform falling or tilting. It cannot guarantee the safety of the steel platform. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides an overall lifting steel platform self-climbing power system, which aims to improve the problem in the prior art that when the power device fails or encounters an emergency, there is a lack of effective safety protection mechanism, which may lead to accidents such as the steel platform falling or tilting, and thus cannot guarantee the safety of the steel platform.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a self-climbing power system for an integral lifting steel platform, comprising a guide rail frame and two connecting shells. A climbing seat is fixedly connected to the left side of the inner wall of the guide rail frame. Hydraulic rods are fixedly connected to the left and right sides of the top wall of the bottom connecting shell. The top ends of the two hydraulic rods are respectively fixedly connected to the left and right sides of the bottom wall of the top connecting shell. A fixing shell is fixedly connected to the front side of the inner wall of the connecting shell. A servo motor is fixedly connected to the inner wall of the fixing shell. A climbing gear is fixedly connected to the output end of the servo motor. The climbing gear meshes with the climbing seat. Support plates are fixedly connected to the left and right sides of the inner wall of the connecting shell. An electric push rod is fixedly connected to the front side of the support plate. A brake plate is fixedly connected to the front end of the electric push rod. The middle part of the fixing shell is slidably connected to the middle front part of the guide rail frame. Auxiliary components are provided at the left and right ends of the front side of the guide rail frame. An installation mechanism is provided at the front side of the connecting shell.

[0006] The above technical solution enables the climbing gear to rotate under the drive of the servo motor. The connecting shell then rotates on the right side of the climbing seat via the climbing gear to complete the lifting and lowering. In case of emergency, the brake plate is driven by one end of the electric push rod to complete the displacement, so that its front side is pressed against the front side of the inner wall of the guide rail frame, achieving the purpose of emergency braking and avoiding the situation where the safety of the steel platform cannot be well guaranteed.

[0007] As a further description of the above technical solution:

[0008] The mounting mechanism includes two fixing plates, the rear sides of which are respectively fixedly connected to the front sides of the corresponding connecting shells. A mounting bracket is provided on the front side of the fixing plate. Fixing grooves are opened on the left and right ends of the rear side of the mounting bracket. The front side of the fixing plate engages with the fixing grooves. Connecting plates are fixedly connected to the left and right ends of the front side of the inner wall of the mounting bracket. A threaded post is threadedly connected to the top wall of the connecting plate. The bottom end of the threaded post penetrates the top wall of the fixing plate and is threadedly connected to the inner bottom wall of the mounting bracket. A cap is fixedly connected to the top of the connecting plate. Mounting grooves are opened on the left and right sides of the top wall of the mounting bracket.

[0009] The above technical solution enables the threaded column to rotate synchronously when the cap is rotated, causing it to separate from the threaded connecting plate and the fixed plate, thus achieving the initial unlocking of the mounting bracket. Subsequently, by pulling the mounting bracket forward, it is separated from the front side of the fixed plate, achieving the effect of disassembling the mounting bracket. Conversely, installation can be completed by pulling it backward. This improves the convenience of adapting and installing on steel platforms and can adapt to the installation effect of steel platforms of different specifications.

[0010] As a further description of the above technical solution:

[0011] The auxiliary component includes two auxiliary gear seats, the rear sides of which are fixedly connected to the left and right ends of the front side of the guide rail frame, respectively. A dual-head motor is fixedly connected to each adjacent side of the two fixed shells. An auxiliary gear is fixedly connected to the output end of the dual-head motor, and the auxiliary gear meshes with the auxiliary gear seat.

[0012] The above technical solution enables the auxiliary gear to rotate on the front side of the auxiliary gear seat under the drive of the dual-head motor, thereby assisting the connecting shell in lifting operations.

[0013] As a further description of the above technical solution:

[0014] The installation mechanism also includes multiple rubber shells, the inner walls of which are respectively fixedly connected to the outer walls of the corresponding fixing plates.

[0015] The above technical solution improves the fixing effect when the fixing plate and the fixing groove are engaged, thanks to the connection of the rubber shell.

[0016] As a further description of the above technical solution:

[0017] A controller is fixedly connected to the front side of the bottom connecting shell. The controller is electrically connected to the hydraulic rod, servo motor, electric push rod and dual-head motor respectively.

[0018] The above technical solution enables the device to be turned on and off when connected to a controller.

[0019] As a further description of the above technical solution:

[0020] The outer walls of the multiple screw caps are fixedly connected with multiple protrusions, and the multiple protrusions are arranged in an equidistant ring.

[0021] The above technical solution improves the protection of the outer wall of the screw cap by connecting multiple convex strips.

[0022] As a further description of the above technical solution:

[0023] Mounting bases are fixedly connected to the bottom of the front and rear sides of the guide rail frame. Multiple stress plates are fixedly connected to the top of the mounting bases. One side of each stress plate is fixedly connected to the outer side of the guide rail frame.

[0024] The above technical solution facilitates the fixed installation of the bottom of the guide rail frame by connecting the mounting base and the stress plate.

[0025] As a further description of the above technical solution:

[0026] Each of the brake plates has a rubber plate fixedly connected to its front side, and the rubber plates are all designed symmetrically.

[0027] The above technical solution improves the static friction of the brake plate during braking by connecting the rubber plates, thus enhancing the braking effect.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the top connecting shell is displaced by the top of the hydraulic rod, which allows the distance between the two connecting shells to be adjusted. Then, under the rotation of the climbing gear driven by the servo motor, the connecting shell is driven to complete the lifting and lowering purpose through the climbing seat. In case of emergency, the brake plate is displaced by the drive of one end of the electric push rod, so that its front side is pressed against the front side of the inner wall of the guide rail frame, thereby achieving the purpose of emergency braking and avoiding the situation where the safety of the steel platform cannot be well guaranteed.

[0030] 2. In this utility model, the rotation of the threaded column separates it from the interior of the corresponding connecting plate and fixing plate, thus achieving the purpose of initially unlocking the mounting bracket. Subsequently, by pulling the mounting bracket forward, the fixing groove inside it separates from the front side of the fixing plate, thus achieving the effect of disassembling the mounting bracket. Conversely, installation can be completed, which improves the convenience of adapting to the installation of steel platforms, thereby adapting to the installation effect of steel platforms of different specifications and improving the flexibility of the device.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a self-climbing power system for an integral lifting steel platform, comprising a guide rail frame 1 and two connecting shells 4. A climbing seat 3 is fixedly connected to the left side of the inner wall of the guide rail frame 1, allowing it to move to the right side of the climbing seat 3 via the rotation of a climbing gear 8. Hydraulic rods 5 are fixedly connected to the left and right sides of the top wall of the bottom connecting shell 4, with the top ends of the two hydraulic rods 5 respectively fixedly connected to the left and right sides of the bottom wall of the top connecting shell 4. Driven by the top ends of the hydraulic rods 5, the height of the top connecting shell 4 can be adjusted, thereby adjusting the distance between the two connecting shells 4. A fixed shell 6 is fixedly connected to the front side of the inner wall of the connecting shell 4, and a servo motor 7 is fixedly connected to the inner wall of the fixed shell 6. A climbing gear 8 is fixedly connected to the output end of the servo motor 7, meshing with the climbing seat 3. Driven by the servo motor 7, the climbing gear 8 can drive the corresponding connecting shell 4 to perform lifting operations. The left and right sides of the inner wall of the connecting shell 4 are fixedly connected to... A support plate 9 is connected to the front side of the support plate 9, and an electric push rod 10 is fixedly connected to the front end of the electric push rod 10. A brake plate 11 is fixedly connected to the front end of the electric push rod 10. When braking, the front end of the electric push rod 10 drives the brake plate 11 to move forward and then press against the front side of the inner wall of the guide frame 1 to achieve the purpose of braking. The middle part of the fixed shell 6 is slidably connected to the middle part of the front side of the guide frame 1. Auxiliary components are provided on the left and right ends of the front side of the guide frame 1. An installation mechanism 2 is provided on the front side of the connecting shell 4. The auxiliary components include two auxiliary gear seats 13. The rear sides of the two auxiliary gear seats 13 are fixedly connected to the left and right ends of the front side of the guide frame 1, so that the auxiliary gear 15 can move up and down on the front side of the auxiliary gear seat 13 under the connection of the auxiliary gear seat 13. A double-head motor 14 is fixedly connected to the adjacent side of the two fixed shells 6. The output end of the double-head motor 14 is fixedly connected to the auxiliary gear 15. The auxiliary gear 15 meshes with the auxiliary gear seat 13 to achieve the effect of assisting the connecting shell 4 to move up and down.

[0040] Specifically, by activating the hydraulic rod 5, the pushing force at its top can drive the top connecting shell 4 to complete the displacement operation, thereby adjusting the distance between the two connecting shells 4 to initially adapt to the steel platform and facilitate subsequent installation work. Driven by the servo motor 7, the climbing gear 8 begins to rotate. Since the climbing gear 8 is meshed with the climbing seat 3, when the climbing gear 8 rotates and displaces on the right side of the climbing seat 3, it can effectively drive the corresponding connecting shell 4 to perform lifting and lowering operations. At the same time, under the coordinated drive of the dual-head motor 14, the auxiliary gear 15 rotates and displaces synchronously on the front side of the auxiliary gear seat 13, further assisting the lifting and lowering of the connecting shell 4. In case of emergency, the brake plate 11 is displaced by the drive of the front end of the electric push rod 10. The front side of the brake plate 11 is tightly attached to the front side of the inner wall of the guide rail frame 1 to achieve the effect of emergency braking, thereby ensuring that the two connecting shells 4 can stop displacement in time, effectively avoiding the problem of not being able to guarantee the safety of the steel platform during operation.

[0041] Reference Figure 1 , Figure 2 and Figure 5 The installation mechanism 2 includes two fixing plates 201. The rear sides of the two fixing plates 201 are respectively fixedly connected to the front sides of the corresponding connecting shells 4. A mounting bracket 202 is provided on the front side of the fixing plate 201. The left and right rear ends of the mounting bracket 202 are provided with fixing grooves 203, so that the steel platform can be installed and connected under the connection of the mounting bracket 202. The front side of the fixing plate 201 engages with the fixing groove 203. The left and right front ends of the inner wall of the mounting bracket 202 are fixedly connected with connecting plates 204. The engagement of the front side of the fixing plate 201 with the fixing groove 203 completes the installation of the mounting bracket 202. For the initial connection, the top wall of the connecting plate 204 is threaded with a threaded post 205. The bottom end of the threaded post 205 penetrates the top wall of the fixing plate 201 and is threaded to the inner bottom wall of the mounting frame 202. Through the rotational connection of the threaded post 205, the connection and locking between the fixing plate 201 and the mounting frame 202 are strengthened. The top of the connecting plate 204 is fixedly connected with a cap 206, which facilitates the rotation of the threaded post 205. The top wall of the mounting frame 202 is provided with mounting grooves 207 on both the left and right sides, which facilitates the installation and fixing of the steel platform.

[0042] Specifically, the distance between the two connecting shells 4 can be adjusted by controlling the hydraulic rod 5 to adapt to different installation requirements. After the distance is adjusted, the rotation of the cap 206 drives the threaded column 205 to rotate and move, so that the threaded column 205 can separate from the internal structure of the corresponding connecting plate 204 and the fixing plate 201, thereby achieving the initial goal of unlocking the mounting bracket 202. By pulling the mounting bracket 202 forward, the fixing groove 203 inside the mounting bracket 202 is disengaged from the front side of the fixing plate 201, completing the separation of the entire mounting bracket 202, thereby achieving the purpose of disassembling the mounting bracket 202. Conversely, by taking the same steps but in the opposite direction, the mounting bracket 202 and the fixing plate 201 can be reinstalled, improving the device's adaptability to steel platforms and enabling it to flexibly adapt to the installation requirements of various steel platforms of different specifications, thereby increasing the device's flexibility and applicability.

[0043] Reference Figure 1 , Figure 4 and Figure 5 The installation mechanism 2 also includes multiple rubber shells 209, the inner walls of which are fixedly connected to the outer walls of the corresponding fixing plates 201; a controller 16 is fixedly connected to the front side of the bottom connecting shell 4, and the controller 16 is electrically connected to the hydraulic rod 5, the servo motor 7, the electric push rod 10 and the dual-head motor 14 respectively; multiple convex strips 208 are fixedly connected to the outer walls of multiple screw caps 206, and the multiple convex strips 208 are arranged in an equidistant ring.

[0044] Specifically, the multiple rubber shells 209 improve the fixing effect when the fixing plate 201 and the fixing groove 203 are engaged. The controller 16, which is electrically connected to the hydraulic rod 5, the servo motor 7, the electric push rod 10 and the dual-head motor 14 respectively, enables the controller 16 to open and close the equipment. The multiple protrusions 208 protect the outer wall of the cap 206.

[0045] Reference Figure 1 , Figure 2 and Figure 3 Mounting bases 17 are fixedly connected to the bottom of the front and rear sides of the guide rail frame 1. Multiple stress plates 18 are fixedly connected to the top of the mounting bases 17. One side of each stress plate 18 is fixedly connected to the outer side of the guide rail frame 1. Rubber plates 12 are fixedly connected to the front side of each brake plate 11. The multiple rubber plates 12 are all designed symmetrically.

[0046] Specifically, the connection between the mounting base 17 and the stress plate 18 improves the stability of the guide rail frame 1, and the connection through the rubber plate 12 increases the static friction of the brake plate 11, thereby enhancing the braking effect.

[0047] Working Principle: Upon initial use, the hydraulic rod 5 is activated, causing its top end to move the top connecting shell 4, thus adjusting the distance between the two connecting shells 4 to achieve initial adaptation to the steel platform for installation. Subsequently, driven by the servo motor 7, the climbing gear 8 rotates. Since the climbing gear 8 is meshed with the climbing seat 3, it rotates on the right side of the climbing seat 3, thereby driving the corresponding connecting shell 4 to lift and lower. Simultaneously, driven by the dual-head motor 14, the auxiliary gear 15 rotates synchronously on the front side of the auxiliary gear seat 13, assisting in the lifting and lowering of the connecting shell 4. In case of emergency, the electric push rod 10 is driven at its front end to move the brake plate 11, causing the front side of the brake plate 11 to press against the front side of the inner wall of the guide rail frame 1. This achieves emergency braking, bringing the two connecting shells 4 to a stop and preventing compromises in the safety of the steel platform. After adjusting the distance between the two connecting shells 4 using the hydraulic rod 5, the rotation of the cap 206 causes the threaded column 205 to rotate synchronously, separating it from the corresponding connecting plate 204 and fixing plate 201. This initially unlocks the mounting bracket 202. Pulling the mounting bracket 202 forward releases the internal fixing groove 203 from the front of the fixing plate 201, disassembling the mounting bracket 202. Conversely, pulling it forward allows for the installation of the mounting bracket 202 and fixing plate 201, improving the adaptability to different steel platform specifications and increasing the device's flexibility.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
