Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a suspended adjustable climbing frame and platform combination device for high-altitude operations. Background Art

[0002] With the continuous development and progress of the construction industry, safety, greenness and efficiency have become the tenets of the construction industry. In the process of construction, there will be high-altitude operations, such as the installation and fixation of steel structure wall beams and the welding of steel structure beams. However, when the ground is uneven or the working space does not meet the requirements of articulated boom trucks and climbing, it is necessary to set up a frame or use simple devices to carry out high-altitude operations, and its safety and efficiency are not outstanding.

[0003] However, in actual use, the following deficiencies still exist, such as: the existing high-altitude work suspended adjustable climbing frame and platform combination device cannot stably fix the ladder and the platform on the high structure. When the ladder and the platform cannot be stably fixed, the personnel working at height may lose balance and fall at any time due to the shaking and shifting of the ladder. For personnel who work on ladders and platforms for a long time, the unstable state will make them always in a state of tension, increasing the probability of accidents. For example, in some high-altitude equipment installation work scenes that require delicate operation, workers may not be able to concentrate on the operation for fear of imbalance, and a slight carelessness may cause a fall accident. The frequent shaking and shifting of the ladder and the platform will cause the joints between the components to be constantly impacted and rubbed, accelerating the wear of the equipment.

[0004] Therefore, the present invention proposes a high-altitude operation suspended adjustable climbing frame and platform combination device to solve the above-mentioned problems. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to provide a suspended adjustable climbing frame and platform combination device for high-altitude operations.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a suspended adjustable climbing frame and platform combination device for high-altitude operation, comprising:

[0007] Climbing frame;

[0008] Support and fixing component. The support and fixing component includes a support frame fixed to the top of the climbing frame. A hydraulic push rod is installed inside the support frame. The output end of the hydraulic push rod is fixed with a connecting block. A hook is fixed on the connecting block. The hook is slidably connected to the support frame. A rotating shaft is rotatably connected to one side of the support frame away from the hydraulic push rod. A clamping block is slidably connected to one side of the support frame away from the hook. A rotating block is rotatably connected to the rotating shaft. A limiting groove is formed on the rotating block. Limiting blocks are fixed on both the hook and the clamping block. The limiting blocks are slidably connected in the limiting groove;

[0009] Support platform component. The support platform component includes a support cross bar rotatably connected to the climbing frame. A clamping strip is fixed on the support cross bar. A platform board is arranged on the support cross bar. A clamping groove is fixed on the support cross bar. The support cross bar is arranged in the clamping groove.

[0010] Furthermore, anti-slip rubber is fixed on the platform board. A protective rod is threadedly connected to the platform board. A first steel wire rope is arranged on the protective rod.

[0011] The beneficial effect of adopting the above further scheme is that the anti-slip rubber fixed on the surface of the platform board prevents personnel from slipping when walking and working on the platform board by increasing the friction with the soles of the operators' shoes or tools, ensuring operation safety. The protective rod is connected to the platform board by threads and can be stably installed at the edge of the platform board. The first steel wire rope arranged on it can further enhance the protection effect and prevent personnel from accidentally falling, providing multiple safety protections for high-altitude operators.

[0012] Furthermore, a first hook is fixed on the platform board. A second hook is fixed on the climbing frame.

[0013] The beneficial effect of adopting the above further scheme is that the first hook on the platform board and the second hook on the climbing frame are connected by a second steel wire rope to form a reliable connection structure.

[0014] Furthermore, a second steel wire rope is arranged on the second hook. The other end of the second steel wire rope is arranged on the first hook. A magnet is fixed on the climbing frame.

[0015] The beneficial effect of adopting the above further scheme is that when the device is suspended for operation, the second steel wire rope is tightened, tightly connecting the platform board and the climbing frame, sharing the load of the platform board and enhancing the overall stability. At the same time, in case of an emergency, this connection structure can play an emergency protection role to prevent the platform board from separating from the climbing frame. The magnet on the climbing frame can adsorb the support cross bar. When the support cross bar is not in use, the support cross bar is adsorbed on the magnet to prevent the support cross bar from affecting the normal work of the operator.

[0016] Furthermore, a buffer assembly is provided on a side of the climbing frame away from the supporting platform assembly, and the buffer assembly includes a support seat fixed on a side of the climbing frame close to the bottom.

[0017] The beneficial effect of adopting the above further solution is that in the buffer assembly, the support seat provides basic support for the bottom of the climbing frame to prevent the climbing frame from tilting when in use.

[0018] Furthermore, a buffer damper is fixed on the climbing frame, and a support plate is fixed to the other end of the buffer damper.

[0019] The beneficial effect of adopting the above further scheme is that the buffer damping and the telescopic spring work together. When the climbing frame is impacted by external force, the two absorb and buffer energy, reduce the vibration amplitude, prevent the climbing frame from shaking violently, and ensure the safety of the operators and the stable operation of the device.

[0020] Furthermore, a telescopic spring is provided on the buffer damper, one end of the telescopic spring is fixed on the climbing frame, and the other end of the telescopic spring is fixed on the support plate.

[0021] The beneficial effects of adopting the above further scheme are: buffer damping absorbs kinetic energy, telescopic spring assists rebound and reset, and reduces instantaneous impact force when the climbing frame is impacted by external force.

[0022] Furthermore, the hook is in the shape of a 匚-shaped hook, and one end of the hook close to the connecting block is sleeved on the surface of the support frame and can slide, and the clamping block has the same shape as the hook and is shorter than the hook.

[0023] The beneficial effect of adopting the above further solution is that the hook and the clamping block cooperate with each other to tightly fix the entire device on the high structure, thereby ensuring the stability and safety of the device when operating at a high place.

[0024] Compared with the prior art, the advantages and positive effects of the present invention are:

[0025] 1. When the device needs to be used, start the hydraulic push rod in the support fixing assembly, the hydraulic push rod extends, and pushes the connecting block and the hook to slide on the support frame. Since the hook and the rotating block cooperate with each other through the limit block and the limit slot, the movement of the hook will drive the rotating block to rotate around the rotating shaft, and then pull the clamp block to slide on the support frame, so that the hook and the clamp block cooperate to fix the device on the high structure, and then rotate the support cross bar in the support platform assembly to expand it. The card strip can assist in fixing the position of the support cross bar, and the platform plate is fixed on the support cross bar through the card slot to form a stable working platform to meet the needs of high-altitude operations;

[0026] 2. When the operator activates the support and fixation component, the hydraulic power unit starts to deliver stable pressure to the system. Under the action of fluid mechanics, the hydraulic push rod generates an axial extension movement, pushing the connecting block to perform a directional displacement along the preset track of the support frame. The connecting block and the hook adopt a wedge interlocking structure, which converts the linear movement into a rotational torque through geometric constraint relationships during the sliding process. The limiting mechanism between the hook and the rotating block forms a kinematic pair coupling. When the hook generates a horizontal displacement, the limiting block slides in the arc-shaped guiding groove, forcing the rotating block to deflect at an angle around the center of the rotating shaft. The rotational movement of the rotating block is transmitted to the clamping block assembly through the link mechanism, and the roller guide system at the bottom of the clamping block converts the rotational torque into the radial displacement of the clamping mechanism. During this process, the double-inclined-plane self-locking device begins to take effect: as the clamping block approaches the support surface, the normal pressure at the contact point gradually increases. When the clamping force reaches the critical value, the static friction force generated by the sudden change of the friction coefficient forms a self-reinforcing effect, ensuring a rigid connection between the device and the building structure. At the same time, the anti-rebound ratchet mechanism intervenes to prevent clamping loosening caused by pressure fluctuations in the hydraulic system;

[0027] 3. This application adopts a multi-level safety redundancy design: at the mechanical level, two-way mechanical stops are set for all kinematic pairs to prevent accidental overtravel; the hydraulic circuit is configured with dual independent safety valves to ensure that more than 70% of the rated pressure can still be maintained when a single component fails. The electrical control system implements a three-level interlock protection: the displacement sensor continuously monitors the deformation of the support frame. When an abnormal vibration spectrum is detected, it automatically activates the emergency brake; the inclinometer continuously measures the levelness of the platform and dynamically adjusts the hydraulic legs to compensate for foundation settlement; the weight detection module restricts the overloading of the platform. When the load reaches the critical value, it triggers an audible and visual alarm and cuts off the power output;

[0028] 4. The interaction between the support system and the building structure presents multi-modal characteristics: for flat facades such as concrete shear walls, the elastic gasket inside the clamping block undergoes adaptive deformation under the contact pressure, increasing the effective contact area; when facing irregular surfaces such as steel structure trusses, the replaceable jaw module adjusts the clamping angle through a universal joint to ensure the balanced distribution of the three-point contact stress. During the locking process, the intelligent pressure sensing system continuously monitors the loads at each support point. When it detects that the single-point stress concentration exceeds the safety threshold, the control system automatically triggers the fine-tuning program and redistributes the clamping force through the hydraulic flow divider.

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] As Figures 1-5 shown, this embodiment provides a technical solution: a suspended adjustable climbing frame and platform combination device for high-altitude operations, including:

[0041] climbing frame 1;

[0042] Support and fixation component 2, the support and fixation component 2 includes a support frame 21 fixed to the top of the climbing frame 1, a hydraulic push rod 22 is installed inside the support frame 21, a connecting block 23 is fixed to the output end of the hydraulic push rod 22, a hook 24 is fixed to the connecting block 23, the hook 24 is slidably connected to the support frame 21, a rotating shaft 25 is rotatably connected to one side of the support frame 21 away from the hydraulic push rod 22, a clamping block 26 is slidably connected to one side of the support frame 21 away from the hook 24, a rotating block 27 is rotatably connected to the rotating shaft 25, a limiting groove 28 is formed in the rotating block 27, limiting blocks 29 are fixed to both the hook 24 and the clamping block 26, and the limiting blocks 29 are slidably connected in the limiting groove 28;

[0043] Support platform component 3, the support platform component 3 includes a support cross bar 31 rotatably connected to the climbing frame 1, a clamping bar 32 is fixed to the support cross bar 31, a platform plate 33 is arranged on the support cross bar 31, a clamping groove 34 is fixed to the support cross bar 31, the support cross bar 31 is arranged in the clamping groove 34. When the climbing frame 1 needs to be used, first operate the support and fixation component 2. After starting the hydraulic push rod 22, the output end of the hydraulic push rod 22 pushes the connected connecting block 23 and the hook 24 to slide along the support frame 21. Since the limiting block 29 on the hook 24 cooperates with the limiting groove 28 of the rotating block 27, the sliding of the hook 24 will drive the rotating block 27 to rotate around the rotating shaft 25, and the rotation of the rotating block 27, through the cooperation of the limiting groove 28 and the limiting block 29 on the clamping block 26, pulls the clamping block 26 to slide on the support frame 21. Finally, the hook 24 and the clamping block 26 cooperate with each other to tightly fix the whole device on the high structure, ensuring the stability and safety of the device during high-altitude operations. After the fixation is completed, then operate the support platform component 3, rotate the support cross bar 31 to expand it, the clamping bar 32 on the support cross bar 31 plays a role in assisting to fix the position of the support cross bar 31 and ensuring it is in a proper and stable state. Then, fix the platform plate 33 to the support cross bar 31 through the clamping groove 34, thus forming a stable operation platform. This platform can bear the weight of the operators and related tools, providing a solid and reliable operation space for high-altitude operations, so as to meet the actual needs of various high-altitude operations.

[0044] In the above solution, there is still a problem that when the climbing frame 1 is subjected to external impact, it cannot meet the requirement of preventing the climbing frame 1 from shaking violently and ensuring the safety of the operators and the stable operation of the device, such as Figures 1-2 and Figures 4-5As shown in the figure: An anti-slip rubber 35 is fixed on the platform board 33. A protective rod 36 is threadedly connected to the platform board 33. A first steel wire rope 37 is arranged on the protective rod 36. The anti-slip rubber 35 fixed on the surface of the platform board 33 increases the friction with the soles of the operators' shoes or tools, preventing people from slipping when walking or working on the platform board 33 and ensuring operation safety. The protective rod 36 is connected to the platform board 33 by threads and can be stably installed on the edge of the platform board 33. The first steel wire rope 37 arranged on it can further enhance the protective effect and prevent people from accidentally falling, providing multiple safety protections for high-altitude operators. A first hook 38 is fixed on the platform board 33, and a second hook 39 is fixed on the climbing frame 1. The first hook 38 on the platform board 33 and the second hook 39 on the climbing frame 1 are connected by a second steel wire rope 310 to form a reliable connection structure. The second steel wire rope 310 is arranged on the second hook 39, and the other end of the second steel wire rope 310 is arranged on the first hook 38. A magnet 311 is fixed on the climbing frame 1. When the device is suspended for operation, the second steel wire rope 310 is tightened, tightly connecting the platform board 33 and the climbing frame 1, sharing the load of the platform board 33 and enhancing the overall stability. At the same time, in case of emergencies, this connection structure can play an emergency protection role to prevent the platform board 33 from separating from the climbing frame 1. The magnet 311 on the climbing frame 1 can adsorb and support the cross bar 31. When the cross bar 31 is not in use, the cross bar 31 is adsorbed on the magnet 311 to prevent the cross bar 31 from affecting the normal work of the operator;

[0045] As Figure 1 and Figure 4 As shown in the figure, a buffer assembly 4 is arranged on one side of the climbing frame 1 away from the support platform assembly 3. The buffer assembly 4 includes a support seat 41 fixed on the climbing frame 1 near the bottom side. In the buffer assembly 4, the support seat 41 provides basic support for the bottom of the climbing frame 1 to prevent the climbing frame 1 from tilting during use. A buffer damper 42 is fixed on the climbing frame 1, and the other end of the buffer damper 42 is fixed with a support plate 43. The buffer damper 42 and the telescopic spring 44 work together. When the climbing frame 1 is subjected to an external impact, the two absorb and buffer energy, reducing the vibration amplitude and preventing the climbing frame 1 from shaking violently, ensuring the safety of the operators and the stable operation of the device. A telescopic spring 44 is arranged on the buffer damper 42. One end of the telescopic spring 44 is fixed on the climbing frame 1, and the other end of the telescopic spring 44 is fixed on the support plate 43. The buffer damper 42 absorbs kinetic energy, and the telescopic spring 44 assists in rebounding and resetting to reduce the instantaneous impact force when the climbing frame 1 is subjected to an external impact.

[0046] Working principle:

[0047] As Figures 1-5As shown in the figure, when the climbing frame 1 needs to be used, first operate the support and fixation component 2. After starting the hydraulic push rod 22, a thrust is generated at its output end, pushing the connecting block 23 to drive the hook 24 to slide along the support frame 21. Since the limiting blocks 29 on the hook 24 and the clamping block 26 cooperate with the limiting grooves 28 on the rotating block 27, when the hook 24 slides, it will drive the rotating block 27 to rotate around the rotating shaft 25. Then, through the linkage between the limiting groove 28 and the limiting block 29 on the clamping block 26, the clamping block 26 is pulled to slide, tightly fixing the entire device on the high-altitude structure, ensuring the stability and safety of the device during high-altitude operations, preventing the device from shifting or falling when the operator is working at height. After the fixation is completed, unfold the support platform component 3, rotate the support cross bar 31 to unfold it, and the clamping strips 32 on the support cross bar 31 play a role to assist in fixing the position of the support cross bar 31. Subsequently, fix the platform board 33 on the support cross bar 31 through the card slots 34. Through the limiting effect of the card slots 34, the platform board 33 is stably installed, forming a platform for operators to move and operate. The anti-slip rubber 35 on the surface of the platform board 33 increases friction to prevent personnel from slipping. The guardrail 36 is installed on the edge of the platform board 33 by threads, and with the first steel wire rope 37, it reduces the risk of personnel falling. The first hook 38 on the platform board 33 and the second hook 39 on the climbing frame 1 are connected by the second steel wire rope 310. When the device is suspended for operation, the second steel wire rope 310 is tightened, which not only shares the load of the platform board 33 and enhances the overall stability, but also prevents the platform board 33 from separating from the climbing frame 1 in case of emergencies. The magnet 311 on the climbing frame 1 can adsorb and fix the support cross bar 31 when it is idle, avoiding the shaking of the support cross bar 31 from affecting the operation. In addition, the support base 41 provides basic support for the bottom of the climbing frame 1, enhancing the bottom stability of the device. When the climbing frame 1 is impacted by external forces, the buffer damper 42 quickly absorbs the impact kinetic energy, and the telescopic spring 44 assists it to rebound and reset. The two work together to effectively reduce the vibration amplitude of the climbing frame 1 and ensure the safety of the operators.

[0048] The above is only a preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
