Description

Technical Field

[0001] The present application relates to the field of lifting equipment, and in particular to a steel structure hoist and a method for using the same. Background Art

[0002] As a lifting equipment, hoists are widely used in the transportation and delivery of goods between different floors of large industrial plants, warehouses and other buildings. They have the advantages of easy installation and high transportation efficiency.

[0003] In the related art, the elevator includes a lifting frame, a hanging basket and a lifting drive, wherein the hanging basket slides vertically in the frame, and the lifting drive is connected to the hanging basket driving device to drive the hanging basket to rise and fall along the frame to travel back and forth between floors.

[0004] With respect to the above-mentioned related technologies, during the use of the current hoist, due to the limitation of the internal space of the hanging basket, it is inconvenient for workers to carry and move goods inside the hanging basket. Therefore, there is room for improvement. Summary of the invention

[0005] In order to facilitate the loading and unloading of cargo in a hoist basket, the present application provides a steel structure hoist and a method for using the same.

[0006] The present application provides a steel structure hoist and a method of using the same, which adopts the following technical solutions: A steel structure hoist comprises a hoisting frame, a hanging basket and a hoisting drive component, wherein the hanging basket slides vertically in the hoisting frame, the hoisting drive component is drivingly connected to the hanging basket, and the hoisting drive component is used to drive the hanging basket to rise and fall vertically along the hoisting frame; a loading platform is also supported on the bottom wall of the inner cavity of the hanging basket, and a sliding drive component is provided in the inner cavity of the hanging basket corresponding to the loading platform, the sliding drive component is drivingly connected to the loading platform, and the sliding drive component is used to drive the loading platform to slide horizontally in a direction close to or away from the inner cavity of the hanging basket.

[0007] By adopting the above technical solution, when loading goods into the hanging basket, the sliding drive component drives the loading platform to slide to the outside of the hanging basket, and after the goods to be transported are transferred to the loading platform, the sliding drive component drives the loading platform to slide the goods to the inner cavity of the hanging basket to complete the loading of the goods. When moving the goods out of the hanging basket, the sliding drive component drives the loading platform to slide the goods to the outside of the hanging basket, and then the goods are moved away from the loading platform to complete the removal of the goods. Compared with the traditional method of transporting and loading goods in the limited space of the hanging basket, the sliding drive component drives the loading platform to move out of or into the inner cavity of the hanging basket, which makes it convenient for operators to load and unload goods outside the hanging basket, reduces the difficulty of loading and unloading goods due to the limitation of the internal space of the hanging basket, and is conducive to reducing the difficulty of loading and unloading goods in the hanging basket.

[0008] Preferably, the sliding drive member comprises a sliding cylinder horizontally supported on the bottom wall of the inner cavity of the hanging basket, and the end of the piston rod of the sliding cylinder is connected to the bottom of the loading platform through a connecting block.

[0009] By adopting the above technical solution, the sliding oil cylinder can subsequently drive the piston rod to extend and retract, thereby driving the loading platform to slide in the horizontal direction, making the sliding operation of the loading platform simpler and more convenient.

[0010] Preferably, a plurality of supporting structures are installed at the bottom of the loading platform, and the supporting structure includes a support, and a roller is rotatably connected to the bottom of the support, and the roller is arranged to abut against the bottom wall of the inner cavity of the hanging basket.

[0011] By adopting the above technical solution, on the one hand, a number of supporting structures can be used to assist in supporting the loading platform, thereby limiting the subsequent external loads applied to the loading platform from being concentrated on the connection between the sliding cylinder and the loading platform, causing the connection between the sliding cylinder and the loading platform to be easily damaged; on the other hand, the rollers on the supporting structure can effectively reduce the friction between the loading platform and the bottom wall of the inner cavity of the hanging basket and the floor, thereby making the sliding of the loading platform smoother and smoother.

[0012] Preferably, the top of the support is connected to the bottom of the loading platform through a connecting piece, and the connecting piece includes a connecting sleeve vertically downwardly connected to the bottom of the loading platform, and a connecting column is slidably inserted at the bottom end of the connecting sleeve, and the bottom end of the connecting column is connected to the support; an airbag connecting part is also provided between the connecting sleeve and the connecting column, and the airbag connecting part includes a first support airbag, and the top and bottom ends of the first support airbag are both connected to connecting plates, and the connecting plates at both ends of the first support airbag are respectively connected to the top wall of the inner cavity of the connecting sleeve and the top of the connecting column, and the first support airbag is connected to a first air pipe, and the first air pipe is passed through the outside of the connecting sleeve.

[0013] By adopting the above technical solution, during the actual use of the hoist, due to the wear of various parts of the hoist and the change of the basket load, the bottom wall of the basket cavity cannot remain absolutely flush with the floor, resulting in the subsequent loading platform being moved out of the basket. The bottom roller of the loading platform cannot contact the ground, causing the support structure to be unable to support the loading platform. Through the setting of the connecting piece, when there is a height difference between the bottom wall of the basket cavity and the floor, the first air pipe can be used to inflate the first support airbag, and the first support airbag is used to expand and drive the support and roller to move downward until the roller contacts the floor, so that the support structure can always support the loading platform.

[0014] Preferably, an installation opening is provided on the loading platform, an auxiliary conveyor belt is embedded in the installation opening, and the conveying direction of the auxiliary conveyor belt is arranged parallel to the sliding direction of the loading platform; the auxiliary conveyor belt is used to move the goods located on the loading platform.

[0015] By adopting the above technical solution and setting up the auxiliary conveyor belt, when the goods are subsequently loaded onto the loading platform, the auxiliary conveyor belt on the loading platform can be used to assist in moving and adjusting the position of the goods, thereby facilitating the loading and unloading of the goods on the loading platform.

[0016] Preferably, a support plate is also provided at the bottom of the loading platform, the support plate is bent at opposite sides to form bent ends, the bent ends are connected to the bottom of the loading platform, the support plate is provided with a lifting drive component corresponding to the auxiliary conveyor belt, the lifting drive component includes a plurality of vertically arranged lifting cylinders, and the top end of the lifting cylinder piston rod is connected to the auxiliary conveyor belt.

[0017] By adopting the above technical solution and setting the lifting drive member, on the one hand, after adjusting the position of the goods through the auxiliary conveyor belt, the corresponding auxiliary conveyor belt can be driven downward by the lifting drive member to separate the auxiliary conveyor belt from the goods, which is beneficial to reduce the situation where the auxiliary conveyor belt is easily damaged due to the long-term concentrated weight of the goods on the auxiliary conveyor belt; on the other hand, when removing the goods on the loading platform subsequently, the corresponding auxiliary conveyor belt can be driven upward by the lifting drive member until the goods are pushed off the loading platform, so as to facilitate the removal of the goods from the loading platform.

[0018] Preferably, a gap is left between the bottom of the support plate and the bottom wall of the inner cavity of the hanging basket.

[0019] By adopting the above technical solution, the contact between the bottom of the support plate and the bottom wall of the inner cavity of the hanging basket is limited, which is helpful to reduce the situation where the support plate contacts the bottom wall of the inner cavity of the hanging basket when the subsequent sliding drive drives the loading platform to slide, causing interference with the sliding of the loading platform.

[0020] Preferably, a support ring is connected to the bottom of the support plate, a gap is left between the bottom of the support ring and the bottom wall of the inner cavity of the hanging basket, a second support airbag is embedded in the inner periphery of the support ring, the second support airbag is connected to a second air pipe, and the second air pipe is passed through the outside of the support ring.

[0021] By adopting the above technical solution, when the loading platform is not sliding, the second support airbag is inflated so that the second support airbag expands and extends out of the support ring and abuts against the bottom wall of the inner cavity of the hanging basket or the floor, thereby achieving auxiliary support for the support plate and improving the overall structural strength of the support plate; when the loading platform needs to slide, the gas in the second support airbag is released so that the second support airbag shrinks into the support ring, thereby limiting the second support airbag from interfering with the sliding of the loading platform.

[0022] Preferably, a method for using a steel structure hoist comprises the following steps: S1: The hanging basket is in place: the lifting driving member drives the hanging basket to slide along the lifting frame to the designated floor; S2: Cargo loading: The loading platform is driven to slide to the outside of the hanging basket by the sliding drive member; the cargo to be transported is moved to the loading platform; S3: Loading platform reset: The loading platform is driven to slide toward the inner cavity of the hanging basket by the sliding drive member until the loading platform drives the goods to slide into the inner cavity of the hanging basket; S4: Cargo lifting: The lifting drive drives the hanging basket to drive the cargo to slide along the lifting rack to the designated floor; S5: Cargo removal: The cargo is moved away from the loading platform by driving the loading platform to slide to the outside of the hanging basket through the sliding drive.

[0023] By adopting the above technical solution, when loading and unloading goods into the hanging basket, the sliding drive component drives the loading platform to move out to the outside of the hanging basket, and then the goods are loaded and unloaded, which effectively reduces the difficulty in loading and unloading goods due to the limited internal space of the hanging basket, making the cargo loading and unloading operation of the hoist hanging basket simpler and more convenient.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: 1. When loading goods into the hanging basket, the sliding drive component first drives the loading platform to move out of the hanging basket. After the goods are moved onto the loading platform, the sliding drive component drives the loading platform to drive the goods to slide into the inner cavity of the hanging basket. When transferring goods from the hanging basket, the sliding drive component drives the loading platform to slide out of the hanging basket, and then the goods are moved away from the loading platform. There is no need to carry and move the goods inside the hanging basket, which is conducive to reducing the difficulty of loading and unloading goods in the hoisting basket.

[0025] 2. After the sliding drive component drives the loading platform to slide out of the outside of the hanging basket, air is inflated into the first supporting airbag through the first air pipe to expand the first supporting airbag and drive the support and the roller to move downward until the roller at the bottom of the loading platform abuts against the floor surface, thereby ensuring the effective support of the loading platform by the supporting structure and reducing the situation in which the supporting structure cannot support the loading platform after the loading platform is moved out of the hanging basket due to the height difference between the bottom wall of the inner cavity of the hanging box and the floor surface.

[0026] 3. By laying out an auxiliary conveyor belt on the loading platform, when subsequently loading and unloading goods onto the loading platform, the auxiliary conveyor belt on the loading platform can be used to assist in moving and adjusting the position of the goods.

DETAILED DESCRIPTION

[0034] The following is combined with Figure 1-6 This application is described in further detail.

[0035] The present application discloses a steel structure hoist and a method of using the same. Figure 1 , comprising a lifting frame 1, a hanging basket 2 and a lifting drive member, the hanging basket 2 is vertically slidably connected to the lifting frame 1, and the lifting drive member is drivingly connected to the hanging basket 2 to drive the hanging basket 2 to vertically rise and fall along the lifting frame 1. The hanging basket 2 is provided with an opening on one side. A loading platform 4 is supported on the bottom wall of the inner cavity of the hanging basket 2, and a sliding drive member is also provided in the inner cavity of the hanging basket 2, and the sliding drive member is drivingly connected to the loading platform 4 to drive the loading platform 4 to slide in the horizontal direction toward or away from the inner cavity of the hanging basket 2.

[0036] When loading and unloading goods into the hanging basket 2 later, the sliding drive member can drive the loading platform 4 located in the hanging basket 2 to slide out to the outside of the hanging basket 2, and then the goods can be loaded and unloaded on the loading platform 4.

[0037] Reference Figure 1 and Figure 2 The lifting frame 1 is welded and assembled by steel structural components. Slide rails 11 are supported on opposite sides of the inner cavity of the lifting frame 1. Two sliding members are provided on the top of the hanging basket 2 corresponding to the two slide rails 11. The sliding members include a slide seat 211. The slide seat 211 is connected to the outside of the hanging basket 2. The slide seat 211 is horizontally rotated with two pulleys 212 corresponding to the slide rail 11. The two pulleys 212 are respectively located on opposite sides of the corresponding slide rail 11, and the two pulleys 212 are both in contact with the corresponding slide rail 11. Through the above settings, the hanging basket 2 is slidably connected to the lifting frame 1.

[0038] The lifting drive component includes a lifting cylinder 3, which is vertically supported on one side of the lifting frame 1. A pulley block is arranged on the top of the lifting frame 1. The top section of the piston rod of the lifting cylinder 3 is connected to a lifting cable 31 through an anchor. The lifting cable 31 is wound around the pulley block on the top of the frame, and the end of the lifting cable 31 away from the lifting cylinder 3 is connected to the top of the hanging basket 2, so that the lifting drive component is driven and connected to the hanging basket 2.

[0039] Reference Figure 3 and Figure 4 The sliding drive member includes two sliding cylinders 5 installed on the bottom wall of the inner cavity of the hanging basket 2. The sliding cylinders 5 are located at the bottom of the loading platform 4, and the sliding cylinders 5 are both opened toward the side of the hanging basket 2. The end of the piston rod of the sliding cylinder 5 is connected to the bottom of the loading platform 4 through a connecting block 51; subsequently, the sliding cylinder 5 drives its own piston rod to extend and retract, so as to drive the loading platform 4 to slide in the horizontal direction.

[0040] Reference Figure 3 and Figure 5 , a plurality of supporting structures 41 are supported on both sides of the bottom of the loading platform 4, and the supporting structures 41 include a support 411, the top of the support 411 is connected to the bottom of the loading platform 4 through a connecting piece, and the bottom of the support 411 is rotatably connected to a roller 412, and the roller 412 abuts against the bottom wall of the inner cavity of the hanging basket 2. Through the above arrangement, on the one hand, a plurality of supporting structures 41 can be used to realize auxiliary support for the loading platform 4, so as to limit the subsequent external load placed on the loading platform 4 to be concentrated on the connection between the piston rod of the sliding cylinder 5 and the loading platform 4, which is conducive to improving the stress condition of the connection between the piston rod of the sliding cylinder 5 and the loading platform 4, so that the sliding cylinder 5 can better drive the loading platform 4 to slide; on the other hand, the friction between the supporting structure and the bottom wall of the inner cavity of the hanging basket 2 and the floor surface can be effectively reduced by the roller, so that the subsequent loading platform 4 is smoother.

[0041] The connecting part includes a connecting sleeve 413, an airbag connecting part 414 and a connecting column 415. The connecting sleeve 413 is welded vertically downward to the bottom of the loading platform 4, the top of the connecting sleeve 413 is sealed, the airbag connecting part 414 is located in the inner cavity of the connecting sleeve 413, the connecting column 415 is slidably inserted into the bottom end of the connecting sleeve 413, and the bottom end of the connecting column 415 is welded to the top of the support 411; the airbag connecting part 414 includes a first supporting airbag 4141, the first supporting airbag 4141 is connected to a first air pipe 4143, and one end of the first air pipe 4143 away from the first supporting airbag 4141 is penetrated to the periphery of the connecting sleeve 413 and connected to the air source. The top and bottom of the first support airbag 4141 are connected with a connecting plate 4142, the outer periphery of the connecting plate 4142 is adapted to the inner periphery of the connecting sleeve 413, the top connecting plate 4142 of the first support airbag 4141 is connected to the top wall of the inner cavity of the connecting sleeve 413, and the bottom connecting plate 4142 of the first support airbag 4141 is connected to the top of the connecting column 415.

[0042] Through the setting of the connecting parts, when the loading platform 4 is subsequently driven to extend out of the hanging basket 2 and move to the floor through the sliding driving part, the air source inflates the first supporting airbag 4141 through the first air pipe 4143, so that the first supporting airbag 4141 expands and drives the connecting column 415 to drive the support 411 and the roller 412 to move downward until the roller 412 abuts against the floor, thereby realizing the effective support of the loading platform 4 by the supporting structure 41, which is beneficial to reduce the situation where the supporting structure 41 is unable to support the loading platform 4 when there is a height difference between the bottom wall of the inner cavity of the hanging basket 2 and the corresponding floor due to component wear or changes in the load of the hanging basket 2.

[0043] Reference Figure 3 and Figure 6 , an installation opening 40 is provided on the loading platform 4, and auxiliary conveyor belts 6 are evenly distributed in the installation opening 40. In the present embodiment, the auxiliary conveyor belt 6 specifically adopts a chain plate conveyor belt. The transmission direction of the auxiliary conveyor belt 6 is arranged parallel to the sliding direction of the loading platform 4; the auxiliary conveyor belt 6 is used to assist in moving and adjusting the position of the goods on the loading platform 4. A support plate 61 is supported at the bottom of the loading platform 4. The two opposite ends of the support plate 61 are bent and the tops of the two bent ends of the support plate 61 are welded to the bottom of the loading platform 4, so that the support plate 61 is firmly installed at the bottom of the loading platform 4. A gap is left between the bottom of the support plate 61 and the bottom wall of the inner cavity of the hanging basket 2, which is conducive to limiting the interference between the support plate 61 and the bottom wall of the inner cavity of the hanging basket 2 and the floor when the loading platform 4 slides later. The support plate 61 is provided with two sets of lifting driving members corresponding to the two auxiliary conveyor belts 6, and the lifting driving members are used to drive the corresponding auxiliary conveyor belts 6 to rise and fall vertically, and the lifting driving members include a plurality of lifting oil cylinders 62, and the plurality of lifting oil cylinders 62 are vertically mounted upward on the support plate 61, and the plurality of lifting oil cylinders 62 are evenly distributed on opposite sides of the corresponding auxiliary conveyor belts 6. The piston rods of the lifting oil cylinders 62 are all connected to the side of the frame of the corresponding auxiliary conveyor belt 6.

[0044] Through the above arrangement, when loading and unloading goods on the loading platform 4 later, the corresponding auxiliary conveyor belt 6 is driven upward by the lifting drive member so that the conveying plane of the auxiliary conveyor belt 6 abuts against the goods on the loading platform 4, and the auxiliary conveyor belt 6 is used to assist in adjusting the position of the moving goods on the loading platform 4, so as to facilitate the loading and unloading of goods. After the auxiliary conveyor belt 6 completes the adjustment and movement of the goods position, the corresponding auxiliary conveyor belt 6 can be driven downward by the lifting drive member until the auxiliary conveyor belt 6 is separated from the goods, so as to reduce the situation where the cargo load is concentrated on the auxiliary conveyor belt 6 for a long time, causing the auxiliary conveyor belt 6 to be easily damaged. At the same time, when unloading the goods on the loading platform 4, the auxiliary conveyor belt 6 can be driven upward by the lifting drive member to push the goods off the surface of the loading platform 4, so as to facilitate workers or handling equipment to better move the goods from the loading platform 4.

[0045] A support ring 63 is also welded and fixed at the bottom of the support plate 61. A gap is left between the bottom end face of the support ring 63 and the bottom wall of the inner cavity of the hanging basket 2. A second support airbag 64 is installed on the inner periphery of the support ring 63. The second support airbag 64 is connected to a second air pipe. One end of the second air pipe away from the second support airbag 64 is passed through the outer periphery of the support ring 63 and connected to the air source. Later, when the loading platform 4 does not move, the air source injects gas into the second support airbag 64 through the second air pipe, so that the second support airbag 64 expands to the bottom wall of the inner cavity of the hanging basket 2 or the floor surface to support the support plate 61, which is beneficial to improve the overall structural strength of the support plate 61 and reduce the deformation and damage of the support plate 61. When the loading platform 4 moves, the air source extracts the gas in the second support airbag 64 through the second air pipe, so that the second support airbag 64 shrinks into the second support ring 63, reducing the interference of the second support airbag 64 with the sliding of the loading platform 4.

[0046] A method for using the above steel structure hoist comprises the following steps: S1: The hanging basket 2 is in place: the hanging basket 2 is driven to slide along the lifting frame 1 to a designated floor by the lifting drive member.

[0047] S2: Cargo loading: The sliding drive member drives the loading platform 4 to slide to the outside of the hanging basket 2; the cargo to be transported is moved to the loading platform 4. During this period, the auxiliary conveyor belt 6 on the loading platform 4 assists in adjusting the cargo to the designated position, and the lifting drive member on the bottom support plate 61 of the loading platform 4 drives the auxiliary conveyor belt 6 to move downward until the auxiliary conveyor belt 6 is separated from the cargo.

[0048] S3: The loading platform 4 is reset: the loading platform 4 is driven by the sliding drive member to drive the cargo to slide toward the inner cavity of the hanging basket 2 until the loading platform 4 drives the cargo to slide into the inner cavity of the hanging basket 2.

[0049] S4: Cargo lifting: The lifting driving member drives the hanging basket 2 to drive the cargo to slide along the lifting frame 1 to the designated floor.

[0050] S5: Cargo removal: After the cargo loading platform 4 is driven by the sliding drive component to slide the cargo to the outside of the hanging basket 2, the cargo is removed from the cargo loading platform 4.

[0051] When loading and unloading goods into the hanging basket 2 of the elevator, the present application drives the loading platform 4 to slide out to the outside of the hanging basket 2 through the sliding drive member in the hanging basket 2, and then the goods are loaded and unloaded on the loading platform 4, so that there is a larger operating space for loading and unloading operations of the goods, reducing the difficulty in loading and unloading of goods due to the internal space limitation of the hanging basket 2, making the loading and unloading of goods in the hanging basket 2 simpler and more convenient.

[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
