Description

Technical Field

[0001] This utility model relates to the field of hoisting frame technology, and in particular to an auxiliary hoisting frame for steel cages. Background Technology

[0002] Track slabs are reinforced concrete structures laid beneath railway rails to support them. To improve the strength of the track slabs, reinforcing cages are pre-installed inside during the casting process. Currently, the reinforcing cages for track slabs are typically installed into pre-excavated pits or holes using a hoisting method. During hoisting, at least two crane booms are usually used to lift both ends and adjust the track's posture in the air.

[0003] In current technology, the lifting frames for track slab reinforcement cages are equipped with multiple fixed hook positions, making it difficult to adjust them according to the required lifting length of the reinforcement cage. This results in low adaptability and limited practicality.

[0004] Therefore, it is necessary to provide a new auxiliary hoisting frame for steel cages to solve the above-mentioned technical problems. Utility Model Content

The adjusting member passes through the installation block and is connected to the limiting hoop, and the adjusting member is threadedly connected to the installation block. The end of the limiting hoop away from the adjusting member forms a limiting groove that matches the contour of the limiting block. The adjusting member can drive the limiting hoop closer to or away from the limiting block so that the limiting block is engaged or disengaged from the limiting groove.

[0009] Optionally, the lifting mechanism further includes a fixed seat and a second lifting assembly.

[0024] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0025] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered by the claims.

[0026] This utility model proposes an auxiliary hoisting frame for rebar cages, which aims to solve the problem that existing auxiliary hoisting frames for rebar cages cannot adapt to rebar cages of different sizes.

[0027] like Figures 1 to 5 As shown, the auxiliary lifting frame for rebar cages includes an installation frame 1, a lifting mechanism 2, and a drive mechanism 3. The installation frame 1 is connected to the lifting equipment. The lifting mechanism 2 includes a moving component 2.1 and at least two first lifting components 2.2 symmetrically arranged on the moving component 2.1. The moving component 2.1 is mounted on the installation frame 1, and the first lifting components 2.2 are used to connect to the rebar cage. The drive mechanism 3 is mounted on the installation frame 1, and the output shaft of the drive mechanism 3 is connected to the moving component 2.1. The drive mechanism 3 can drive the moving component 2.1 to move the two first lifting components 2.2 closer to or further apart from each other. In actual operation, the drive mechanism 3 can drive the moving component 2.1 to move the two first lifting components 2.2 closer to or further apart from each other to adjust the distance between the two first lifting components 2.2. This allows the position of the hooks 2.2.3 to be changed according to requirements, solving the problem that existing auxiliary lifting frames for rebar cages cannot adapt to rebar cages of different sizes and improving the adaptability of the auxiliary lifting frame for rebar cages.

[0028] The movable component 2.1 includes a bidirectional lead screw 2.1.1 and a movable nut seat 2.1.2. The bidirectional lead screw 2.1.1 is rotatably mounted on the mounting frame 1 along its length. It is connected to the output shaft of the drive mechanism 3 and has symmetrically arranged first and second threads, with opposite directions of rotation. Each first lifting component 2.2 has a corresponding movable nut seat 2.1.2, and the movable nut seats 2.1.2 of the two first lifting components 2.2 are threadedly connected to the bidirectional lead screw 2.1.1 via the first and second threads, respectively. The drive mechanism 3 drives the bidirectional lead screw 2.1.1 to rotate, causing the two movable nut seats 2.1.2 to move closer or further apart via the first and second threads, thereby adjusting the distance between the two first lifting components 2.2 and enabling the lifting of steel cages of different sizes.

[0029] Furthermore, the drive mechanism 3 includes an operating handwheel 3.1 and a limiting block 3.2 connected to each other. The operating handwheel 3.1 is connected to the bidirectional lead screw 2.1.1 through the limiting block 3.2. The auxiliary hoisting frame for the rebar cage also includes a limiting mechanism 4, which includes an mounting block 4.1, an adjusting member 4.2, and a limiting hoop 4.3. The mounting block 4.1 is mounted on the mounting frame 1. The adjusting member 4.2 passes through the mounting block 4.1 and is connected to the limiting hoop 4.3, and the adjusting member 4.2 is threadedly connected to the mounting block 4.1. The end of the limiting hoop 4.3 away from the adjusting member 4.2 forms a limiting groove 4.3.1 that matches the contour of the limiting block 3.2. The adjusting member 4.2 can drive the limiting hoop 4.3 to move closer to or away from the limiting block 3.2 so that the limiting block 3.2 is engaged or disengaged from the limiting groove 4.3.1. The operator rotates the handwheel 3.1 to drive the limiting block 3.2 and the bidirectional lead screw 2.1.1 connected to the limiting block 3.2, thereby adjusting the distance between the two first lifting components 2.2. After the distance between the two first lifting components 2.2 is adjusted to the correct position, the adjusting component 4.2 is rotated to move the limiting hoop 4.3 closer to the limiting block 3.2, and it engages with the limiting block 3.2 through the limiting groove 4.3.1, thereby locking the drive mechanism 3. When it is necessary to adjust the steel cage of different sizes, the adjusting component 4.2 is rotated in the opposite direction to move the limiting hoop 4.3 away from the limiting block 3.2, thereby disengaging from the limiting groove 4.3.1 and engaging the locking limit of the drive mechanism 3. The limiting mechanism 4 can effectively lock and limit the drive mechanism 3, preventing the bidirectional lead screw 2.1.1 from rotating and slipping during the lifting operation, and enhancing the stability of the first lifting components 2.2 after the position is adjusted. In this embodiment, the limiting block 3.2 has a square structure.

[0030] Furthermore, the lifting mechanism 2 also includes a fixed seat 2.3 and a second lifting assembly 2.4. The fixed seat 2.3 is mounted on the mounting frame 1, and a bidirectional lead screw 2.1.1 passes through the fixed seat 2.3 and slides in contact with it. The second lifting assembly 2.4 is mounted on the fixed seat 2.3. Two first lifting assemblies 2.2 are symmetrically arranged about the second lifting assembly 2.4. The second lifting assembly 2.4 is fixedly mounted on the mounting frame 1 via the fixed seat 2.3 and works in conjunction with the two first lifting assemblies 2.2 to lift the reinforcing cage, further improving the stability of the lifting operation. The symmetrical arrangement of the two first lifting assemblies 2.2 about the second lifting assembly 2.4 ensures that the connection points of the lifting mechanism 2 on the reinforcing cage are evenly distributed, thus ensuring the balance of the reinforcing cage during the lifting process, preventing tipping, and ensuring operational safety.

[0031] Specifically, the first lifting assembly 2.2 and the second lifting assembly 2.4 have the same structure. The first lifting assembly 2.2 includes a lifting lug 2.2.1, a lifting rope 2.2.2, and a hook 2.2.3. The lifting lug 2.2.1 of the first lifting assembly 2.2 is connected to the movable nut seat 2.1.2, and the lifting lug 2.2.1 of the second lifting assembly 2.4 is connected to the mounting frame 1. The hook 2.2.3 is connected to the lifting lug 2.2.1 via the lifting rope 2.2.2. The hook 2.2.3 is used to hang on the reinforcing cage and is connected to the lifting lug 2.2.1 via the lifting rope 2.2.2. The lifting rope 2.2.2 can both pull the reinforcing cage through the hook and ensure a certain degree of flexibility, improving the convenience of operation.

[0032] In this embodiment, the auxiliary hoisting frame for the reinforcing cage also includes a transmission mechanism 5; there are two hoisting mechanisms 2, symmetrically arranged on the mounting frame 1. The bidirectional lead screw 2.1.1 of one hoisting mechanism 2 is connected to the output shaft of the drive mechanism 3, and the bidirectional lead screws 2.1.1 of both hoisting mechanisms 2 are connected via the transmission mechanism 5. The two hoisting mechanisms 2 work together to hoist the reinforcing cage, further enhancing the stability and safety of the hoisting operation, making it suitable for hoisting large-size reinforcing cages.

[0033] The transmission mechanism 5 includes a chain 5.2 and two sprockets 5.1. The sprockets 5.1 are rotatably mounted on the mounting frame 1, and the two sprockets 5.1 are respectively sleeved on two double-acting lead screws 2.1.1. The two ends of the chain 5.2 are respectively wound around the two sprockets 5.1. The transmission using the chain 5.2 and sprockets 5.1 is simple in structure, easy to install, and can ensure transmission efficiency.

[0034] The mounting frame 1 includes a frame body 1.1, a first reinforcing beam 1.2, and a second reinforcing beam 1.3. The bottom of both sides of the frame body 1.1 along its width direction forms movable grooves 1.1.1 that extend along its length direction. Two lifting mechanisms 2 are respectively located within the two movable grooves 1.1.1. A mounting groove 1.1.2 is formed on one bottom side of the frame body 1.1 along its length direction. The two ends of the mounting groove 1.1.2 are connected to the two movable grooves 1.1.1 respectively. One through-groove mounting groove 1.1.2 is connected to the driving component, and the other bidirectional lead screw 2.1.1 extends into the mounting groove 1.1.2 and is rotatably connected to the inner wall of the mounting groove 1.1.2. A transmission mechanism 5 is located within the mounting groove 1.1.2. A hollow section 1.1.3 is formed in the middle of the frame body 1.1. The first reinforcing beam 1.2 is located in the hollow section 1.1.3 along the width direction of the frame body 1.1. The inner corners of the frame body 1.1 are each provided with a second reinforcing beam 1.3. The movable slot 1.1.1 includes a connected mounting section and an opening. A movable threaded seat is slidably disposed within the mounting section, and a fixed seat 2.3 is fixedly disposed within the mounting section. The lifting lug 2.2.1 of the first lifting assembly 2.2 is slidably disposed within the opening. The first end of the lifting lug 2.2.1 of the first lifting assembly 2.2 is connected to the movable threaded seat, and the second end extends out of the opening of the movable window and is connected to the lifting rope 2.2.2. The first end of the lifting lug 2.2.1 of the second lifting assembly 2.4 is connected to the fixed seat 2.3, and the second end extends out of the opening of the movable window and is connected to the lifting rope 2.2.2. The two lifting mechanisms 2 are respectively disposed within the two movable slots 1.1.1 and are driven by the transmission mechanism 5 within the mounting slot 1.1.2. This not only avoids interference between the pulling mechanism and the transmission mechanism 5 and the outside, thus providing protection, but also reduces the space occupied by the auxiliary lifting frame for the rebar cage, improving space utilization.

[0035] In addition, the auxiliary hoisting frame for the reinforcing cage also includes a traction mechanism 6, which is mounted on the installation frame 1 and is used to connect with the lifting equipment. The traction mechanism 6 includes a top seat 6.1 and a traction rope 6.2. The top seat 6.1 is located on the top of the installation frame 1 and is connected to the lifting equipment through the traction rope 6.2. In this embodiment, there are four traction mechanisms 6, which are evenly distributed on the installation frame 1 to ensure the stability of the installation frame 1.

[0036] In actual operation, the installation frame 1 is first connected to the lifting equipment using the traction mechanism 6. Then, the steel cage is hooked by multiple hooks 2.2.3 of the lifting mechanism, and the lifting equipment is operated to lift the steel cage. When it is necessary to adjust the position of the outer hook 2.2.3, the adjusting part 4.2 is first rotated to disengage the connecting limit clamp 4.3 from the outside of the limit block 3.2. Then, the operating handwheel 3.1 is rotated to drive the double-acting screw 2.1.1 to rotate. Under the action of the transmission mechanism 5, the two double-acting screws 2.1.1 rotate synchronously, thereby driving the two outer first lifting assemblies 2.2 to move in opposite or opposite directions, changing the distance between the first lifting assembly 2.2 and the second lifting assembly 2.4, and thus changing the position of the hook 2.2.3.

[0037] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
