Description

Technical Field

[0001] This utility model belongs to the field of hoisting technology, specifically relating to an auxiliary device for hoisting steel formwork. Background Technology

[0002] Steel formwork hoisting is a crucial part of building construction, involving the hoisting of precast steel formwork to designated locations using cranes and other equipment. Before construction, it is necessary to ensure the quality of the formwork, the proper functioning of the hoisting equipment, and the safety of the site environment. During hoisting, the formwork must be precisely aligned and securely installed to avoid tilting or colliding with other structures. After installation, the verticality and horizontality of the formwork must be checked to ensure tight connections and prevent grout leakage.

[0003] Problems with existing technology: Existing steel formwork requires auxiliary devices for hoisting, among which hoisting cages are the most common. Small steel formwork pieces are placed inside the hoisting cage, and then a crane lifts the hoisting cage together with the steel formwork to a higher position. This allows for the hoisting of multiple steel formwork pieces at once, improving construction efficiency. However, in strong winds, if the steel formwork pieces inside the hoisting cage are small or the cage is not fully filled, the steel formwork pieces may move and collide with each other inside the hoisting cage without any restraints, which can easily lead to deformation. Utility Model Content

[0004] The purpose of this utility model is to provide a steel formwork hoisting auxiliary device, which can lift the hoisting connecting plate by a crane, pull the sliding base plate upward, and clamp the steel formwork with the top of the hoisting cage to prevent the steel formwork from sliding and colliding during the hoisting cage swaying.

[0005] The specific technical solution adopted by this utility model is as follows: A steel formwork hoisting auxiliary device includes: a hoisting cage, a sealing door connected to one side of the hoisting cage by a hinge, and the hoisting cage being hoisted by a hook; The hoisting cage is equipped with a sliding bottom plate inside, and a steel template is installed above the sliding bottom plate inside the hoisting cage. Guide strips are detachably installed on both sides of the top of the traction rope. The top of both ends of the sliding base plate is fixedly connected with traction ropes, which extend to the guide bar and then to the top of the hoisting cage.

[0006] A hoisting connecting plate is provided at the top of the hoisting cage near the middle of the two guide bars, and the end of the traction rope is fixedly connected to the hoisting connecting plate.

[0007] A carrier plate is fixedly connected to the upper position of the sliding base plate near the inside of the hoisting cage, and the steel template is placed above the carrier plate.

[0008] The end of the sliding base plate is T-shaped and is slidably set with the hoisting cage.

[0009] The two guide bars are fixedly connected to each other on their adjacent sides and at the bottom of the guide bars with detachable feet.

[0010] The hoisting cage has a threaded hole near the disassembly foot, and a disassembly bolt is provided in the middle of the disassembly foot. The disassembly bolt passes through the disassembly foot and is threadedly connected to the threaded hole.

[0011] The guide bar is fixedly connected to an attraction pin near the hoisting cage. The hoisting cage has a positioning groove, and the attraction pin is inserted into the positioning groove.

[0012] Both guide bars have rope holes inside, through which the traction rope passes.

[0013] The two rope holes are elliptical on the side closest to each other, and the top is tilted upwards.

[0014] The top array of the hoisting connection plate is fixedly connected to multiple balance rings, and the multiple balance rings are connected to the hook.

[0015] The technical effects achieved by this utility model are as follows: In this invention, a crane lifts the lifting connection plate, which then transmits the pulling force to the sliding base plate via a traction rope. This pulls the sliding base plate upwards, causing the top of the steel template to contact the top of the lifting cage. The steel template then pushes the lifting cage upwards, and the carrier plate clamps the top of the lifting cage to prevent the steel template from sliding or colliding during the shaking of the lifting cage.

[0016] This invention allows for the replacement of the guide bar by rotating the disassembly bolt to unscrew it from the disassembly foot and threaded hole, then lifting the guide bar upwards to remove the attraction pin from the positioning groove. Attached Figure Description

[0019] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0020] like Figure 1 As shown, a steel formwork hoisting auxiliary device includes: a hoisting cage 1, a sealing door 2 connected to one side of the hoisting cage 1 by a hinge, and the hoisting cage 1 being hoisted by a hook; In traditional hoisting cages, steel templates 4 are placed inside the hoisting cage 1, and then the sealing door 2 is closed before hoisting.

[0021] See attached document Figures 2-3 The hoisting cage 1 has a sliding base plate 6 inside, and a steel template 4 is installed above the sliding base plate 6 inside the hoisting cage 1. The top of both ends of the sliding base plate 6 are fixedly connected to the top of the sliding base plate 6. A hoisting connecting plate 5 is installed at the top of the hoisting cage 1 near the middle of the two guide bars 3. The end of the traction rope 7 is fixedly connected to the hoisting connecting plate 5. A carrier plate 601 is fixedly connected to the upper part of the sliding base plate 6 near the inside of the hoisting cage 1. The steel template 4 is placed above the carrier plate 601. The end of the sliding base plate 6 is T-shaped and slides with the hoisting cage 1.

[0022] According to the above structure, when hoisting is required, the steel template 4 is placed above the carrier plate 601. It can be filled completely or partially. During the filling process, a partition plate can be placed between two adjacent steel templates 4 to prevent the two adjacent steel templates 4 from rigidly contacting each other. When all the steel formwork 4 are placed inside the hoisting cage 1, the hoisting connecting plate 5 can be lifted by the crane. The hoisting connecting plate 5 will transmit the pulling force to the sliding base plate 6 through the traction rope 7, pulling the sliding base plate 6 upward and moving the carrier plate 601 and the steel formwork 4 upward until the top of the steel formwork 4 contacts the top of the hoisting cage 1. The steel formwork 4 pushes the hoisting cage 1 upward, and the carrier plate 601 and the top of the hoisting cage 1 clamp the steel formwork 4, increasing the friction between the steel formwork 4 to achieve the limit. The ends of the sliding base plate 6 are designed to be T-shaped and fit with the square tube of the hoisting cage 1 with clearance to prevent the two ends of the sliding base plate 6 from tilting due to strong winds. Among them, the hoisting cage 1 can be made of materials with low density such as aluminum alloy to prevent excessive pressure on the steel template 4 from causing it to deform.

[0023] See attached document Figures 4-7 The top two sides of the hoisting cage 1 are detachably equipped with guide bars 3, and the traction rope 7 extends to the guide bars 3 and to the top of the hoisting cage 1. The two guide bars 3 are fixedly connected to the side close to each other and the bottom of the guide bars 3 with disassembly feet 301. The hoisting cage 1 is provided with threaded holes near the disassembly feet 301, and a disassembly bolt 303 is provided in the middle of the disassembly feet 301. The disassembly bolt 303 passes through the disassembly feet 301 and is threadedly connected to the threaded holes. The guide bars 3 are fixedly connected to the position of the lifting cage 1 with attraction pins 304. The hoisting cage 1 is provided with positioning grooves, and the attraction pins 304 are inserted into the positioning grooves. The two guide bars 3 are provided with rope holes 302 inside, and the traction rope 7 passes through the rope holes 302. The side of the two rope holes 302 that are close to each other is elliptical and the top is inclined upward. The top of the hoisting connecting plate 5 is fixedly connected with multiple balance rings 8, and the multiple balance rings 8 are connected to the hook.

[0024] According to the above structure, due to the continuous friction between the traction rope 7 and the guide bar 3, the inner wall of the traction rope 7 experiences significant wear during this process and needs to be replaced after a period of time. When replacing the guide bar 3, first rotate the disassembly bolt 303 to unscrew it from the disassembly foot 301 and the threaded hole. Then lift the guide bar 3 upwards and remove the attraction pin 304 from the positioning groove. The attraction pin 304 is tightly fitted with the positioning groove. When the guide bar 3 is subjected to external force, the attraction pin 304 and the positioning groove bear the external force first, converting the external force into internal stress, which protects the disassembly bolt 303. The elliptical end of the rope hole 302 can accommodate the up-and-down swing amplitude of the traction rope 7, preventing the edge of the rope hole 302 from contacting and rubbing against the traction rope 7 during the lifting process. The part of the guide bar 3 that contacts the diameter of the traction rope 7 can be hardened to increase its hardness and wear resistance, such as by quenching or tempering. Multiple balance rings 8 are used to maintain the balance of the lifting connection plate 5, and if one of them breaks, the remaining balance rings 8 can still lift the lifting cage 1, thereby preventing it from falling.

[0025] The working principle of this utility model is as follows: When all the steel templates 4 are placed inside the hoisting cage 1, the hoisting connecting plate 5 can be lifted by the crane. The hoisting connecting plate 5 will transmit the pulling force to the sliding base plate 6 through the traction rope 7, pulling the sliding base plate 6 upward and moving the carrier plate 601 and the steel templates 4 upward until the top of the steel templates 4 contacts the top of the hoisting cage 1. The steel templates 4 push the hoisting cage 1 upward, and the carrier plate 601 and the top of the hoisting cage 1 clamp the steel templates 4, increasing the friction between the steel templates 4 to achieve limiting. When facing strong winds, due to the large friction between the steel templates 4, they will not slide during the swaying of the hoisting cage 1, avoiding the occurrence of collisions.

[0026] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
