Description

Technical Field

[0001] This utility model relates to the field of hoisting tools, and in particular to a hoisting tool for installation. Background Technology

[0002] Grilles are commonly installed in balconies and stairwells of high-rise residential buildings for protection or decoration. In construction of buildings with more than 20 floors, workers use hoisting equipment to lift the grilles from the ground to the corresponding floors, efficiently completing the installation. This solves the problems of inconvenience and low efficiency of manual carrying upstairs, and also ensures the safety of construction workers, avoiding the risks of carrying things at heights.

[0003] A search revealed Chinese Patent Publication No. CN206842848U; this utility model relates to a suspended hoisting tool, including a hoisting frame with several hoisting components on it. Each hoisting component includes a linear sleeve vertically mounted on the hoisting frame and a linear guide rod installed within the linear sleeve. The top end of the linear guide rod extends out of the linear sleeve and is fixed to a limit block at its end; a hook is connected to the lower end of the linear guide rod. A spring is fitted around the outside of the linear sleeve, with both ends of the spring contacting the limit block and the hoisting frame, respectively. A hanging ring is connected to the top of the hoisting frame via several hoisting wire ropes. This utility model allows for quick and convenient lifting and suspending of target objects, avoiding the need for operators to constantly adjust the hoisting tool during hoisting operations, and preventing hooks from easily detaching. In actual hoisting operations, the use of this hoisting tool significantly improves the efficiency and safety of hoisting operations, avoiding dangers such as hook detachment caused by unstable suspension of heavy objects.

[0004] The aforementioned patent specification mentions that "the lifting frame is a rectangular frame, and there are four lifting components, which are arranged at the four corners of the lifting frame. The four corners of the lifting frame are connected to a hanging ring located at the upper center of the lifting frame by four lifting wire ropes." While the ropes in the middle of the above description can be used for lifting, the nylon ropes cannot be cleaned. Over time, a large amount of dust, dirt, and debris will accumulate on the surface of the ropes, not only increasing their weight and slowing down the lifting efficiency, but also accelerating rope wear and aging, reducing strength, and greatly increasing the risk of breakage, endangering personnel safety and the integrity of the lifted items. Furthermore, the cleaning brush cannot be disassembled; after repeated use, the bristles wear down and become dirty, significantly reducing the cleaning effect, yet it cannot be replaced, and it can also breed bacteria that corrode the ropes. In addition, the cleaning brush is easily damaged by collisions during maintenance and storage, and occupies extra space, hindering tool storage and transportation, seriously affecting the proper management and efficient operation of the lifting tools. To address the above problems, a lifting tool for installation is now proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an installation hoisting tool, which aims to improve the problem that some existing devices cannot clean nylon ropes and cannot disassemble cleaning brushes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An installation hoisting tool includes two extension plates and a grid. A connecting rod is rotatably connected inside the two extension plates. Driven wheels are fixedly connected to the left and right sides of the connecting rod. A rope roller is fixedly connected to the outside of the driven wheels. Connecting rods are fixedly connected to the front and rear sides of the bottom of the extension plates. A cleaning and disassembly mechanism is fixedly connected to the bottom of the connecting rod. A nylon rope is fixedly connected to the bottom of the rope roller. An anti-disengagement mechanism is fixedly connected to the other end of the nylon rope.

[0008] The cleaning and disassembly mechanism includes a mounting plate, with sliding rods slidably connected to both the front and rear sides of the mounting plate. A cavity is opened inside the mounting plate, and a limit component is slidably connected inside the cavity. A fixing ring is detachably connected inside the mounting plate, and a cleaning brush is fixedly connected to the outside of the fixing ring. The bottom of the connecting rod is fixedly connected to the outside of the mounting plate.

[0009] The above technical solution mainly consists of two extension plates and a grid. Connecting rods are rotatably connected inside the two extension plates, with a driven wheel fixed on each of their left and right sides. A rope roller is connected to the outside of each driven wheel. A cleaning and disassembly mechanism is installed below the connecting rods on the front and rear sides of the bottom of the extension plates. The cleaning and disassembly mechanism includes a mounting plate, with sliding pull rods slidably connected to its front and rear sides. The plate has an internal cavity containing a slidable limiting component. A fixing ring can also be detached from the mounting plate, and a cleaning brush is fixed to the outside of the fixing ring. The mounting plate is securely connected to the bottom of the connecting rods. A nylon rope is connected to the bottom of the rope roller, and an anti-disengagement mechanism is installed at the other end.

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

[0011] The limiting assembly includes a limiting plate, and a spring is sleeved on the outside of the sliding rod. The limiting plate is slidably connected to the inside of the cavity.

[0012] With the above technical solution, when the sliding rod is subjected to external force, the spring is compressed or stretched, thereby changing the force on the limiting plate. The outside of the limiting plate is tightly fitted with the inside of the cavity, allowing it to slide smoothly. Through the coordinated operation of the sliding rod and the spring, the position of the limiting plate in the cavity is precisely controlled, thereby adjusting the working state of the cleaning and disassembly mechanism.

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

[0014] The anti-disengagement mechanism includes a hook, a rotating shaft rotatably connected to the front of the hook, a rotating baffle fixedly connected to the outside of the rotating shaft, a hook fastener fixedly connected to the top of the hook, a reset assembly provided on the outside of the hook, and the outside of the hook fixedly connected to the bottom of the nylon rope.

[0015] Through the above technical solution, the front of the hook can rotate flexibly via a precision rotating shaft. A rotating baffle is firmly fixed to the rotating shaft. When the hook is in lifting operation, the rotating baffle can open and close flexibly according to the actual situation. A sturdy hook is provided at the top of the hook for connecting the nylon rope, ensuring stability during lifting. A reset component is installed on the outside of the hook. When the object to be lifted is placed in position and the rotating baffle opens, the reset component immediately functions to quickly reset the rotating baffle, preventing the hook from accidentally disengaging. The bottom of the hook is tightly fixed to the nylon rope.

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

[0017] The reset assembly includes a telescopic rod, and a second spring is sleeved on the outside of the telescopic rod. The outside of the telescopic rod is fixedly connected to the outside of the hook.

[0018] Through the above technical solution, a second spring is tightly fitted on the outside of the telescopic rod. The two work together to provide power support for the reset of the rotating baffle. One end of the telescopic rod is firmly fixed to the outside of the hook to ensure a stable connection. When the hook lifts an item, the rotating baffle opens, the telescopic rod is compressed, and the second spring contracts to store energy. Once the item is placed in place, the second spring quickly releases the stored elastic potential energy, pushing the telescopic rod to extend, which in turn drives the rotating baffle to reset quickly, preventing the hook from accidentally disengaging.

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

[0020] The top of the extension plate is fixedly connected to a housing, the outer left side of the housing is fixedly connected to a motor, the drive end of the motor is fixedly connected to a pulley block, the outer left and right sides of the pulley block are fixedly connected to drive wheels, and a belt is sleeved on the outside of the pulley block.

[0021] With the above technical solution, the motor is installed in place and serves as the power source for the entire lifting tool. The drive end of the motor is connected to the pulley block, and a drive wheel is installed on each of the left and right sides of the pulley block. Both of them rotate at high speed with the motor. A tough belt is wrapped around the outside of the pulley block. Driven by the motor, the drive wheel transmits power to the driven wheel efficiently through the belt drive. In this way, the rope roller can rotate smoothly to realize the winding and unwinding of the nylon rope.

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

[0023] Top lifting rings are fixedly connected to the top left and right sides of the top of the grid. A rigging shackle is detachably connected inside the top lifting ring. A steel wire rope is fixedly connected to the outside of the rigging shackle. The other end of the steel wire rope is fixedly connected to the inside of the hook.

[0024] Through the above technical solution, the top lifting ring is made of high-strength material, ensuring stability and reliability, and providing a connection point for lifting the grid. The top lifting ring features a detachable internal structure, compatible with rigging shackles, allowing for simple installation and removal, greatly improving usability. The rigging shackle is externally connected to a robust steel wire rope with excellent tensile strength, capable of withstanding the enormous pulling force during lifting. The other end of the steel wire rope is precisely connected to the inside of the hook, forming a stable lifting link.

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

[0026] Bottom lifting rings are fixedly connected to both the left and right sides of the bottom end of the grid. The outside of the steel wire rope is placed inside the anti-disengagement mechanism through the two bottom lifting rings. Expansion bolts are fixedly connected to the four corners of the bottom end of the grid, and shims are fixedly connected to the bottom of the expansion bolts.

[0027] With the above technical solution, an expansion bolt is installed at each of the four corners of the bottom of the grating. These expansion bolts penetrate deep into the fixing surface, providing strong anchoring force to firmly fix the grating in the installation position. The bottom of the expansion bolts is connected to a shim, which can effectively disperse the pressure of the grating, prevent the installation surface from being damaged due to uneven force, and further enhance the stability of the entire installation structure, ensuring that the grating remains stable during use.

[0028] As a further description of the above technical solution:

[0029] One end of the second spring is fixedly connected to the outside of the rotating baffle, and the other end of the second spring is fixedly connected to the inside of the hook.

[0030] With the above technical solution, when the hook is in operation and the rotating baffle opens due to contact with the heavy object, the second spring is stretched and stores elastic potential energy. Once the hoisted item is placed in place, the hook is no longer under force, and the second spring quickly releases the stored energy. With its own strong rebound force, it pulls the rotating baffle to quickly return to its original position, tightly blocking the opening of the hook and effectively preventing the hoisted item from accidentally coming off the hook.

[0031] This utility model has the following beneficial effects:

[0032] 1. In this utility model, by pulling the sliding rod, the sliding rod can slide inside the cavity through the limiting plate, which in turn allows the limiting plate to compress the spring, causing the spring to deform. This allows the cleaning brush to be removed from inside the mounting plate. When a new cleaning brush is placed in the through hole inside the mounting plate, the sliding rod is released, causing the spring to rebound, thus enabling the installation of the cleaning brush.

[0033] 2. In this utility model, by applying pressure to the rotating baffle with the wire rope, the rotating baffle can compress the telescopic rod, which in turn causes the spring on the outside of the telescopic rod to deform, allowing the wire rope to enter the inside of the hook. At this point, when hoisting the grid, the wire rope will not come out of the inside of the hook. Attached Figure Description

[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0043] Reference Figures 1 to 3 This utility model provides an embodiment of a hoisting tool for installation, comprising two extension plates 5 and a grid 14. The extension plates 5 are rotatably connected to a connecting rod 7. The connecting rod 7 is rotatably connected inside the two extension plates 5, with both ends of the connecting rod 7 inserted into the mounting holes inside the two extension plates 5, ensuring that the connecting rod 7 can rotate flexibly. Driven wheels 8 are fixedly connected to the left and right sides of the connecting rod 7. When the driven wheels 8 are driven to rotate, the driven wheels 8 will drive the connecting rod 7 to rotate, thereby driving the rope roller 9 to rotate, realizing the winding and unwinding of the nylon rope 12, and completing the hoisting operation. The rope roller 9 is fixedly connected to the outside of the driven wheels 8. The main function of the rope roller 9 is to wind and unwind the nylon rope 12. When the driven wheel 8 drives the rope roller 9 to rotate, the nylon rope 12 will be wound or released on the rope roller 9. The bottom front and rear sides of the extension plate 5 are fixedly connected to the connecting rod 10. The bottom of the connecting rod 10 is fixedly connected to the cleaning and disassembly mechanism 11. The bottom of the rope roller 9 is fixedly connected to the nylon rope 12. The nylon rope 12 is woven from high-strength nylon fiber and has the characteristics of light weight, high strength and good flexibility. The surface of the nylon rope 12 is specially treated to increase its wear resistance and anti-aging performance, and can be used for a long time under different environmental conditions. The other end of the nylon rope 12 is fixedly connected to the anti-disengagement mechanism 13. The anti-disengagement mechanism 13 is connected to the object being lifted to realize the lifting operation of the object.

[0044] Specifically, when the hoisting tool is in operation, the two extension plates 5 are first rotatably connected to the connecting rod 7, so that the two ends of the connecting rod 7 are inserted into the mounting holes inside the extension plate 5 and can rotate flexibly. The driven wheels 8 on both sides drive the rope rollers 9 connected to them to rotate, thereby realizing the winding and unwinding of the nylon rope 12. The nylon rope 12 is woven from high-strength nylon fibers, and the surface is specially treated to be wear-resistant and anti-aging. One end is fixed to the bottom of the rope roller 9, and the other end is connected to the anti-disengagement mechanism 13 for connecting with the object to be hoisted to complete the hoisting. The cleaning and disassembly mechanism 11 connected to the bottom of the extension plate 5 through the connecting rod 10 can be used for related maintenance work.

[0045] The anti-disengagement mechanism 13 includes a hook 1301, which is forged from alloy steel and hardened and tempered to have extremely high strength and toughness, capable of withstanding large tensile forces. During use, it must be ensured that the opening of the hook 1301 completely engages the object and remains stable during lifting. A rotating shaft 1302 is rotatably connected to the front of the hook 1301. The main function of the rotating shaft 1302 is to provide rotational support for the rotating baffle 1303. When the hook 1301 engages the object, the rotating baffle 1303 can rotate around the rotating shaft 1302, closing the opening of the hook 1301 and preventing the object from falling off during lifting, thus improving the safety of the lifting operation. The rotating baffle 1303 is fixedly connected to the outside of the rotating shaft 1302. A hook 1306 is fixedly connected to the top of the hook 1301. The hook 1306 serves to connect the hook 1301 and the nylon rope 12 in the anti-disengagement mechanism 13. A reset assembly is provided on the outside of the hook 1301. The reset assembly includes a telescopic rod 1304. When the rotating baffle 1303 rotates to open the opening of the hook 1301, the telescopic rod 1304 will extend as the spring 1305 is stretched. The telescopic rod 1304 is fitted with the spring 1305. The spring 1305 ensures that while meeting the reset requirements of the rotating baffle 1303, the operation will not be affected by excessive elasticity. The telescopic rod 1304 is fixedly connected to the outside of the hook 1301. The hook 1301 is fixedly connected to the bottom of the nylon rope 12.

[0046] Specifically, the hook 1301 is forged from alloy steel and subjected to quenching and tempering treatment, resulting in high strength and toughness. During use, it ensures that its opening completely locks the object in place and remains stable. After the hook 1301 hooks the object, the rotating shaft 1302 provides support for the rotating baffle 1303, causing it to rotate around the rotating shaft 1302, thus closing the opening of the hook 1301 and preventing the object from falling. The hook 1306 connects the hook 1301 to the nylon rope 12. When it is necessary to open the opening, the rotating baffle 1303 rotates, and the telescopic rod 1304 extends as the second spring 1305 stretches. The second spring 1305 satisfies the reset requirement of the rotating baffle 1303 without affecting operational convenience. After reset, the hook 1301 is fixed to the bottom of the nylon rope 12, completing the operation cycle.

[0047] The cleaning and disassembly mechanism 11 includes a mounting plate 1107, which is made of high-strength aluminum alloy. This material combines light weight and high strength, ensuring the stability of the cleaning and disassembly mechanism. Sliding rods 1101 are slidably connected to both the front and rear sides of the mounting plate 1107. The sliding rods 1101 reduce friction when sliding in the grooves inside the mounting plate 1107, ensuring smooth sliding. A cavity 1102 is formed inside the mounting plate 1107. A limiting component is slidably connected inside the cavity 1102. The limiting component includes a limiting plate 1103, the shape of which is adapted to the internal shape of the cavity 1102. It is typically a rectangular flat plate with chamfered edges to prevent scratching the inner wall of the cavity 1102 during sliding. A spring is fitted around the outside of the sliding rods 1101. Spring 1104 has been treated with anti-rust coating, such as anti-rust paint, to prevent rusting during use and to avoid affecting its performance and service life. The limiting plate 1103 is externally slidably connected to the inside of the cavity 1102. The mounting plate 1107 has a detachably connected fixing ring 1105 inside. The main function of the fixing ring 1105 is to fix the cleaning brush 1106, ensuring that the cleaning brush 1106 is stable and reliable during operation and will not fall off due to vibration or external force. The fixing ring 1105 is externally fixedly connected to the cleaning brush 1106. The bristles of the cleaning brush 1106 are made of high-quality nylon, which has good flexibility and wear resistance. It can effectively clean dust, dirt and other impurities on the surface of the lifting tool without scratching the tool surface. The mounting plate 1107 is externally fixedly connected to the bottom of the connecting rod 10.

[0048] Specifically, the mounting plate 1107, made of high-strength aluminum alloy, is lightweight and strong, and is firmly connected to the bottom of the connecting rod 10. The sliding pull rods 1101 on the front and rear sides inside slide smoothly in the groove, reducing friction. The limiting plate 1103 inside the cavity 1102 is adapted to the cavity 1102 and has chamfered edges. It is connected to a spring 1104, which is rust-proofed to ensure performance and life. The mounting plate 1107 is detachably connected to the fixing ring 1105, which firmly fixes the cleaning brush 1106. The bristles of the cleaning brush 1106 are made of high-quality nylon, which is flexible and wear-resistant, and can effectively remove impurities from the surface of the lifting tools without scratching the surface. All components work together to complete the operation of the cleaning and disassembly mechanism.

[0049] Reference Figures 2 to 5The top of the extension plate 5 is fixedly connected to the housing 1. The housing 1 is designed to accommodate and protect the internal components. Its internal space is rationally planned to provide suitable installation positions for components such as the motor 2. The motor 2 is fixedly connected to the left side of the housing 1. The motor 2 is a high-performance servo motor with precise speed control and stable torque output characteristics. Its power and torque are precisely matched according to the overall load and motion requirements of the lifting tool to ensure efficient and stable driving of the pulley block 4. The drive end of the motor 2 is fixedly connected to the pulley block 4. The pulley block 4 is designed to include multiple... Pulleys, through reasonable arrangement and combination, achieve the functions of saving effort and changing the direction of force. The pulley group 4 is fixedly connected to the left and right sides of the outside. The drive wheel 3 drives the pulley group 4 to rotate under the drive of the motor 2. The surface of the pulley group 4 is polished to reduce the friction between it and the belt 6 and improve the transmission efficiency. The pulley group 4 is fitted with a belt 6. The belt 6 is made of high-strength rubber material and has high-strength fiber rope embedded inside, which has good elasticity and wear resistance. The surface of the belt 6 is specially treated to increase the friction between it and the drive wheel 3 and the driven wheel 8.

[0050] Specifically, the housing 1 at the top of the extension plate 5 has a rationally planned internal space to accommodate and protect components such as the motor 2. The high-performance servo motor 2 on the left side of the housing 1 has power and torque matched according to the tool load and motion requirements. The drive end is connected to the pulley block 4. The pulley block 4 consists of multiple pulleys arranged in a reasonable combination, which can save effort and change the direction of force. The surface of the pulleys is polished to reduce friction with the belt 6. The drive wheel 3 drives the pulley block 4 to rotate under the drive of the motor 2. The belt 6 outside the pulley block 4 is made of high-strength rubber material with embedded fiber ropes and a special surface treatment to increase the friction between the drive wheel 3 and the driven wheel 8, thereby achieving stable power transmission.

[0051] Top lifting rings 15 are fixedly connected to both the left and right sides of the top of the grid 14. The top lifting rings 15 are forged from alloy steel and, after quenching and tempering, possess extremely high strength and toughness, capable of withstanding significant tensile forces. A detachable rigging buckle 16 is detachably connected inside the top lifting ring 15. The rigging buckle 16 facilitates the connection and separation of the wire rope 17 from the top lifting ring 15. During the installation and dismantling of the lifting system, operators can quickly connect or separate the wire rope 17 from the top lifting ring 15 by opening or closing the rigging buckle 16. The wire rope 17 is fixedly connected to the outside of the rigging buckle 16. The wire rope 17 is placed inside the anti-disengagement mechanism 13 via two bottom lifting rings 18, enabling the lifting of the grid 14 and the object being lifted. The other end of the wire rope 17 is fixedly connected inside the hook 1301. Bottom lifting rings 18 are fixedly connected to both the left and right sides of the bottom end of the grid 14. They connect the wire rope 17 to the grid 14 and, through the cooperation of the wire rope 17 and the anti-disengagement mechanism 13, ensure the stability of the grid 14 during the hoisting process. The outside of the wire rope 17 is placed inside the anti-disengagement mechanism 13 through the two bottom lifting rings 18. Expansion bolts 19 are fixedly connected to the four corners of the bottom end of the grid 14. The function of the expansion bolts 19 is to provide stable fixation for the grid 14 and prevent the grid 14 from shifting or shaking during the hoisting operation, thus ensuring the safety of the hoisting operation. Shims 20 are fixedly connected to the bottom of the expansion bolts 19. During installation, the grid 14 can be made level by increasing or decreasing the number of shims 20 or adjusting the position of the shims 20, thus ensuring the accuracy and safety of the hoisting operation.

[0052] Specifically, the top lifting rings 15 on both sides of the top of the grille 14 are forged from alloy steel and quenched and tempered, resulting in high strength and toughness. They are connected to the wire rope 17 via rigging shackles 16 for easy installation and disassembly. The other end of the wire rope 17 is placed in the anti-disengagement mechanism 13 via the bottom lifting ring 18 and connected to the hook 1301 to lift the grille 14 and the object being lifted, ensuring its stability during the lifting process. The expansion bolts 19 at the four corners of the bottom of the grille 14 are used to prevent the grille 14 from shifting or shaking during lifting. The shims 20 at the bottom can be increased or decreased in number or adjusted in position to ensure that the grille 14 is in a horizontal state, ensuring the safe and accurate lifting operation.

[0053] Working principle: When cleaning the nylon rope 12, the drive motor 2 drives the drive wheel 3 to rotate, which in turn drives the driven wheel 8 to rotate via the belt 6. Under the rotation of the driven wheel 8, the rope roller 9 passes through the cleaning disassembly mechanism 11 and is rubbed by the cleaning brush 1106, so that the outside of the nylon rope 12 can be cleaned. When replacing the cleaning brush 1106, by pulling the sliding rod 1101, the sliding rod 1101 can slide through the limiting plate 1103 inside the cavity 1102, which in turn allows the limiting plate 1103 to compress the spring 1104, causing the spring 1104 to deform, and thus allowing the cleaning brush 1106 to be removed from the mounting plate 1107. When the new cleaning brush 1106 is placed in the through hole inside the mounting plate 1107, by releasing the sliding rod 1101, the spring 1104 rebounds, thus realizing the installation of the cleaning brush 1106.

[0054] When the hook 1301 is protected against detachment, the wire rope 17 applies pressure to the rotating baffle 1303, which in turn causes the rotating baffle 1303 to compress the telescopic rod 1304. This causes the spring 1305 outside the telescopic rod 1304 to deform, allowing the wire rope 17 to enter the interior of the hook 1301. At this point, when the grid 14 is being hoisted, the wire rope 17 will not detach from the interior of the hook 1301, thus achieving the protection against detachment of the hook 1301.
