Description

Technical Field

[0001] This utility model relates to the field of formwork hoisting technology, and in particular to a hoisting device for installing steel formwork. Background Technology

[0002] Lifting formwork is an auxiliary tool used in the construction process for installing and dismantling concrete components. It is usually made of steel. Existing lifting formwork typically uses clamps to fix concrete structures or other building panels. However, during the lifting process, due to the influence of wind and different gravity distribution, the device is prone to tilting after being raised, which can cause the clamps to loosen and lead to the components or panels falling off, posing certain safety hazards.

[0003] The prior art CN220283276U discloses a hoisting formwork device, including a base plate, an upper plate, and a top block. The top block is installed on the upper part of the upper plate. Hinged blocks are rotatably connected to all four sides of the base plate. Vertical rods are linearly arranged on the upper part of the hinged blocks. Movable rods are movably connected inside the vertical rods. Connecting rods are provided on the upper part of the movable rods. The connecting rods are movably connected to the upper plate. This hoisting formwork device can be laid flat on the ground. By setting up the upper plate and the top block, the upper part of the device is formed. The two parts of the whole device can be separated and can be detachably connected together by inserting rods. Then, the top block is bolted to the crane's rope chain. This device facilitates the installation and removal of components. At the same time, the components no longer need to be clamped by clamps, and the setting of the surrounding vertical rods and movable rods prevents the components from sliding out of the device, greatly improving the safety of the device.

[0004] However, although the vertical and movable rods prevent the template from sliding out of the equipment, the template is prone to collision with the equipment when the equipment shakes due to wind, causing damage. Utility Model Content

[0005] The purpose of this utility model is to provide a hoisting device for steel formwork installation, which solves the problem that although the formwork cannot slide out of the device by setting up vertical rods and movable rods, it is easy for the formwork to collide with the device and be damaged when the device shakes due to wind.

[0006] To achieve the above objectives, this utility model provides a hoisting device for steel formwork installation, including a base plate and an installation mechanism. The installation mechanism includes a protective frame, a movable plate, a limiting component, an anti-slip pad, two buffer components, a cylinder, and a pressure plate. The protective frame is installed above the base plate, and lifting lugs are provided opposite to each other on the protective frame. The outer side wall of the protective frame is provided with mounting holes and multiple ventilation holes. The movable plate is rotatably connected to the base plate. The limiting component is installed on the outer side wall of the protective frame. The anti-slip pad is fixedly connected to the base plate and located above the base plate, and the anti-slip pad is provided with multiple anti-slip patterns. The two buffer components are arranged opposite to each other on the inner side wall of the protective frame. The cylinder is installed above the protective frame, and the output end of the cylinder passes through the protective frame. The pressure plate is fixedly connected to the output end of the cylinder and located inside the protective frame.

[0007] The limiting assembly includes a mounting shaft, a limiting block, a baffle, a handle, and a limiting bolt. The mounting shaft is fixedly connected to the protective frame and located on the outer wall of the protective frame. The limiting block is fixedly connected to the protective frame and located at the end of the protective frame away from the mounting shaft, and the limiting block is provided with a limiting hole. One end of the baffle is rotatably connected to the mounting shaft, and the other end of the baffle is movably connected to the limiting block, and the end of the baffle near the limiting block is provided with a through hole. The handle is fixedly connected to the baffle and located at the end of the baffle near the mounting shaft. The limiting bolt is threaded between the limiting hole, the through hole, and the mounting hole.

[0008] The buffer assembly includes a telescopic rod, a spring, and a buffer plate. One end of the telescopic rod is fixedly connected to the protective frame and located on the inner wall of the protective frame. The buffer plate is fixedly connected to the other end of the telescopic rod and located inside the protective frame. The spring is sleeved on the outer wall of the telescopic rod.

[0009] The hoisting equipment for installing the steel formwork also includes an alarm mechanism, which is located above the protective frame.

[0010] The alarm mechanism includes a wind power detector and an alarm. The wind power detector is installed above the protective frame, and the alarm is electrically connected to the wind power detector and is located above the protective frame.

[0011] This utility model discloses a hoisting device for installing steel formwork. During use, the limiting component is opened, allowing the movable plate to disengage from the limiting position and rotate relative to the base plate. At this time, the operator can place the steel formwork between the two buffer components. After placement, the cylinder is driven to operate, causing the pressure plate to move vertically downwards until it contacts the steel formwork. The positive pressure provided by the cylinder and the pressure plate prevents displacement of the steel formwork during hoisting. During hoisting, the ventilation holes on the protective frame effectively reduce wind resistance, thereby reducing swaying. Furthermore, when displacement occurs, the buffer components cushion the steel formwork, preventing it from directly impacting the equipment and causing damage. This solves the problem that while the vertical and movable rods prevent the formwork from sliding off the equipment, the formwork is prone to collision and damage when the entire equipment sways due to wind.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

Figure 2 This is a schematic diagram of the internal structure of the protective frame according to the first embodiment of this utility model.

[0022] This utility model provides a multi-degree-of-freedom lifting device for segmented turning of offshore platforms, including a base plate 101 and an installation mechanism. The installation mechanism includes a protective frame 102, a movable plate 103, a limiting component, an anti-slip pad 104, two buffer components, a cylinder 105, and a pressure plate 106. The limiting component includes an installation shaft 107, a limiting block 108, a baffle 109, a handle 110, and a limiting bolt 111. The buffer component includes a telescopic rod 112, a spring 113, and a buffer plate 114. The above structure solves the problem that although the vertical rod and movable rod prevent the template from sliding out of the equipment, the template is prone to collision with the equipment and damage when the equipment shakes due to wind.

[0023] In a specific implementation, the base plate 101 is used to install the installation mechanism and is supported by a steel template.

[0024] The protective frame 102 is installed above the base plate 101, and lifting lugs 115 are arranged opposite each other on the protective frame 102. The outer wall of the protective frame 102 has mounting holes and multiple ventilation holes. The movable plate 103 is rotatably connected to the base plate 101. The limiting component is installed on the outer wall of the protective frame 102. The anti-slip pad 104 is fixedly connected to the base plate 101 and located above the base plate 101, and has several anti-slip patterns. Two buffer components are arranged opposite each other on the inner wall of the protective frame 102. The cylinder 105 is installed above the protective frame 102, and the output end of the cylinder 105 penetrates through the protective frame 102. The pressure plate 106 is fixedly connected to the output end of the cylinder 105 and located inside the protective frame 102. The anti-slip pad 104 is used to prevent the steel template from sliding, and the lifting lugs 115 are used to facilitate lifting. When using the hoist, the limiting component is opened, allowing the movable plate 103 to disengage from the limiting position and rotate relative to the base plate 101. At this time, the operator can place the steel template between the two buffer components. After placement, the cylinder 105 is driven to operate, causing the pressure plate 106 to move vertically downwards until the pressure plate 106 contacts the steel template. The positive pressure provided by the cylinder 105 and the pressure plate 106 prevents the steel template from shifting during hoisting. During hoisting, the ventilation holes on the protective frame 102 can effectively reduce wind resistance, thereby reducing swaying. Furthermore, when displacement occurs, the buffer components cushion the steel template, preventing it from directly impacting the equipment and causing damage. This solves the problem that while the vertical and movable rods prevent the template from sliding out of the equipment, the template is prone to collision with the equipment and damage when the equipment shakes due to wind.

[0025] The mounting shaft 107 is fixedly connected to the protective frame 102 and located on the outer side wall of the protective frame 102. The limiting block 108 is fixedly connected to the protective frame 102 and located at the end of the protective frame 102 away from the mounting shaft 107, and the limiting block 108 is provided with a limiting hole. One end of the baffle 109 is rotatably connected to the mounting shaft 107, and the other end of the baffle 109 is movably connected to the limiting block 108. The end of the baffle 109 near the limiting block 108 is provided with a through hole. The handle 110 is fixedly connected to the baffle 109 and located on the outer side wall of the baffle 102. Near the end of the mounting shaft 107, the limiting bolt 111 is threaded between the limiting hole, the through hole, and the mounting hole. When taking or placing the steel template, the limiting bolt 111 is rotated, causing it to sequentially disengage from the mounting hole, the through hole, and the limiting hole. At this time, the baffle 109 loses the limitation of the limiting bolt 111. Pressing the handle 110 downward causes the baffle 109 to rotate relative to the mounting shaft 107 until it lifts off the limiting block 108. At this time, the movable plate 103 can rotate relative to the base plate 101, allowing construction personnel to take or place the steel template.

[0026] One end of the telescopic rod 112 is fixedly connected to the protective frame 102 and located on the inner wall of the protective frame 102. The buffer plate 114 is fixedly connected to the other end of the telescopic rod 112 and located inside the protective frame 102. The spring 113 is sleeved on the outer wall of the telescopic rod 112. When the steel template is displaced due to wind or inertia, it first impacts the buffer plate 114. The buffer plate 114 transmits the impact force to the telescopic rod 112 and the spring 113. The spring 113 is compressed, and the telescopic rod 112 contracts synchronously to limit the movement direction of the buffer plate 114 and prevent the steel template from directly colliding with the equipment and causing damage.

[0027] When using the multi-degree-of-freedom lifting device for segmented turning of offshore platforms according to this utility model, the limiting bolt 111 is rotated to remove the limiting position of the baffle 109. The handle 110 is then pressed downwards, causing the baffle 109 to rotate relative to the mounting shaft 107 until it lifts off the limiting block 108. At this point, the movable plate is no longer limited. Construction workers place the steel formwork between the two buffer plates 114, re-limit the movable plate 103, and then drive the cylinder 105. The cylinder 105 drives the pressure plate 106 to move vertically downwards until... The pressure plate 106 is in contact with the steel template. The positive pressure provided by the cylinder 105 and the pressure plate 106 prevents the steel template from shifting during hoisting. During hoisting, the ventilation holes on the protective frame 102 can effectively reduce wind resistance, thereby reducing swaying. Furthermore, when displacement occurs, the telescopic rod 112, the spring 113, and the buffer plate 114 can prevent direct collision. This solves the problem that the template cannot slide out of the equipment due to the setting of vertical rods and movable rods, but when the equipment shakes due to wind, the template is prone to collision with the equipment, causing damage.

[0028] Second Embodiment

[0029] Please see Figure 5 , Figure 5 This is a schematic diagram of the overall structure of the second embodiment of the present invention.

[0030] Based on the first embodiment, the multi-degree-of-freedom lifting device for segmented turning of offshore platforms of this utility model also includes an alarm mechanism, which includes a wind power detector 201 and an alarm 202.

[0031] In a specific implementation, the alarm mechanism is located above the protective frame 102, and the alarm mechanism is used to monitor wind force and issue an alarm.

[0032] The wind power detector 201 is installed above the protective frame 102. The alarm 202 is electrically connected to the wind power detector 201 and is located above the protective frame 102. The wind power detector 201 is used to monitor wind force. When the wind force is too high, the wind power detector 201 sends a signal to activate the alarm 202, which then sounds an alarm to remind the construction personnel.
