DETAILED DESCRIPTION

[0016] The technical solutions in the present application will be further described below with reference to the drawings and embodiments.

[0017] As Figures 1 to 8 shown in the drawings, the embodiment of the present application provides a connecting channel of an attached lifting scaffold and a tower crane, which is used for connecting the attached lifting scaffold and the tower crane, so as to move workers between the attached lifting scaffold and the tower crane.

[0018] Please refer to Figure 1 , Figure 2 and Figure 5The connecting passage between the attached lifting scaffold and the tower crane comprises a bottom plate 1 mounted on the attached lifting scaffold, one side of the bottom plate 1 is provided with a receiving groove 11, the opening of the receiving groove 11 is directed towards the tower crane, the receiving groove 11 is provided with a retractable plate 2 and a retractable assembly 3 for driving the retractable plate 2 to extend out of the receiving groove 11 or retract into the receiving groove 11. When the retractable plate 2 is driven by the retractable assembly 3 to extend out of the receiving groove 11, one end of the retractable plate 2 extending out of the receiving groove 11 moves towards the tower crane until the retractable plate 2 is overlapped on the tower crane, at this time, the bottom plate 1 and the retractable plate 2 form a pedestrian passage connecting the attached lifting scaffold and the tower crane, workers can pass between the attached lifting scaffold and the tower crane through the bottom plate 1 and the retractable plate 2; when the retractable plate 2 is driven by the retractable assembly 3 to retract into the receiving groove 11, one end of the retractable plate 2 extending out of the receiving groove 11 moves away from the tower crane to separate the retractable plate 2 from the tower crane, at this time, the attached lifting scaffold can climb on the building, after the movement of the attached lifting scaffold is completed, the retractable plate 2 is driven by the retractable assembly 3 to extend out and overlap on the tower crane, the attached lifting scaffold and the tower crane are connected again, without repeated disassembly and assembly, the time required for disassembly and re-assembly of the temporary pedestrian passage between the attached lifting scaffold and the tower crane is effectively saved, thereby improving the construction efficiency.

[0019] In detail, in order to ensure the personal safety of workers passing through the connecting passage between the attached lifting scaffold and the tower crane, the connecting passage between the attached lifting scaffold and the tower crane further comprises a guardrail assembly 4, the number of the guardrail assembly 4 is two, and the two guardrail assemblies 4 are respectively arranged on the opposite sides of the retractable plate 2, the guardrail assembly 4 comprises a first fixed rod 41 arranged on the bottom plate 1 and a second fixed rod 42 arranged on the retractable plate 2, and a rhombic telescopic frame 43 is arranged between the first fixed rod 41 and the second fixed rod 42, and the two ends of the rhombic telescopic frame 43 are respectively rotationally connected with the first fixed rod 41 and the second fixed rod 42. When the retractable plate 2 is driven by the retractable assembly 3 to extend out of the receiving groove 11, the distance between the first fixed rod 41 and the second fixed rod 42 increases, at this time, the rhombic telescopic frame 43 is elongated and protects the workers passing through the retractable plate 2, preventing the workers from accidentally falling off the retractable plate 2, so as to improve the safety of the connecting passage between the attached lifting scaffold and the tower crane; when the retractable plate 2 is driven by the retractable assembly 3 to retract into the receiving groove 11, the distance between the first fixed rod 41 and the second fixed rod 42 decreases, at this time, the rhombic telescopic frame 43 gradually retracts with the movement of the retractable plate 2, thereby preventing the rhombic telescopic frame 43 from affecting the normal movement of the attached lifting scaffold.

[0020] Please refer to Figure 5 andFigure 6 In the embodiment, the telescopic assembly 3 comprises a slider 31, a rocker 32 and a driving mechanism 5. The slider 31 is movably arranged on the telescopic plate 2 and the moving direction of the slider 31 is perpendicular to the moving direction of the telescopic plate 2. The rocker 32 is rotatably connected to the slider 31 at one end and rotatably connected to the base plate 1 at the other end. The receiving slot 11 is provided with an adapter block 14 matched with the rocker 32. The driving mechanism 5 drives the rocker 32 to rotate around the end of the rocker 32 rotatably connected to the base plate 1, i.e. the adapter block 14. When the rocker 32 rotates under the driving of the driving mechanism 5, the rocker 32 pushes or pulls the slider 31, so that the slider 31 moves on the telescopic plate 2 while approaching or moving away from the adapter block 14 in the moving direction of the telescopic plate 2, thereby pulling or pushing the telescopic plate 2 to retract or extend the telescopic plate 2 into or out of the receiving slot 11. The stroke of the telescopic plate 2 can be controlled by controlling the rotation angle of the rocker 32, and the length of the telescopic plate 2 extending out of the receiving slot 11 is controllable, so as to adapt to the distance between the attached lifting scaffold and the tower crane, thereby meeting the use requirements in different situations.

[0021] Specifically, the driving mechanism 5 comprises a cylinder 51 and a first telescopic rod 52 matched with the cylinder 51. The receiving slot 11 is provided with a bracket 15 for mounting the cylinder 51. The first telescopic rod 52 is rotatably connected to a sleeve 53 at the end away from the cylinder 51. The sleeve 53 is sleeved on the rocker 32 and fixedly connected with the rocker 32. The first telescopic rod 52 is driven by the cylinder 51 to extend or shorten, so as to push or pull the rocker 32 to rotate. During the operation of the rocker 32, the sleeve 53 rotates relative to the first telescopic rod 52, so that the rocker 32 can smoothly rotate under the driving of the driving mechanism 5.

[0022] As shown in Figure 5 One side of the telescopic plate 2 extends into the receiving slot 11, and the end of the telescopic plate 2 extending into the receiving slot 11 is provided with a guide rod 21. The axial direction of the guide rod 21 is perpendicular to the moving direction of the telescopic plate 2. The slider 31 is provided with a guide hole matched with the guide rod 21. When the slider 31 is actuated by the rocker 32, the slider 31 moves on the guide rod 21 along the axial direction of the guide rod 21, so that the slider 31 moves stably relative to the telescopic plate 2, and the connection between the slider 31 and the telescopic plate 2 is stable, avoiding the slider 31 from accidentally falling off the telescopic plate 2.

[0023] Preferably, the opposite ends of the telescopic plate 2 are respectively provided with clamping blocks 22, which are arranged close to the side of the telescopic plate 2 extending into the receiving groove 11. The base is further provided with clamping grooves 13 communicating with the receiving groove 11, and the opposite ends of the receiving groove 11 are respectively provided with the clamping grooves 13. The length dimension of the clamping groove 13 is smaller than the width dimension of the receiving groove 11, and the clamping block 22 extends into the clamping groove 13 and is attached to the inner wall of the clamping groove 13. The movement stroke of the clamping block 22 is limited by the clamping groove 13, thereby limiting the maximum stroke of the telescopic plate 2 relative to the base plate 1, and preventing the telescopic plate 2 from being separated from the base plate 1.

[0024] As shown in Figure 5 , Figure 6 and Figure 8 , in order to enable the telescopic plate 2 to move smoothly relative to the base plate 1, a plurality of rotatable first rollers 12 are arranged in the receiving groove 11. The first rollers 12 are arranged in a row on the base plate 1, and the arrangement direction of the first rollers 12 is consistent with the movement direction of the telescopic plate 2. The first rollers 12 are respectively attached to the bottom surface of the telescopic plate 2. When the telescopic plate 2 moves under the drive of the telescopic assembly 3, the first rollers 12 rotate synchronously with the movement of the telescopic plate 2 to reduce the friction between the telescopic plate 2 and the base plate 1, so that the movement of the telescopic plate 2 relative to the base plate 1 is more smooth, and the mutual friction between the telescopic plate 2 and the base plate 1 is avoided to cause damage to the connecting channel of the attached lifting scaffold and the tower crane.

[0025] Optionally, the telescopic plate 2 is a hollow structure, and a plurality of reinforcing ribs 23 are arranged in the telescopic plate 2. The reinforcing ribs 23 are arranged staggered in the telescopic plate 2 to reduce the weight of the telescopic plate 2 while meeting the strength requirement of the telescopic plate 2 for passing through.

[0026] Please refer to Figure 3 , Figure 4 and Figure 7 , the base plate 1 is further provided with a support assembly 6, which includes a connecting plate 61 and a support plate 62 connected to the connecting plate 61. The connecting plate 61 is attached to and fixed on the base plate 1, and the support plate 62 is flush with the opening of the receiving groove 11. When the telescopic plate 2 extends out of the base plate 1, the support plate 62 is attached to the bottom surface of the telescopic plate 2, thereby supporting the telescopic plate 2 through the support assembly 6 to make the movement of the telescopic plate 2 more stable, and preventing workers from stepping on the telescopic plate 2 to cause unintended rotation of the telescopic plate 2 relative to the base plate 1, thereby preventing the telescopic plate 2 from tilting, and further improving the safety of the connecting channel of the attached lifting scaffold and the tower crane.

[0027] In the embodiment, the support assembly 6 further comprises a reinforcing plate 64 which is perpendicular to the connecting plate 61 and the support plate 62 and is fixedly connected with the connecting plate 61 and the support plate 62, so as to further enhance the structural stability of the support assembly 6. The support assembly 6 is in plurality and is arranged on the base plate 1 in a spaced manner, and the arrangement direction of the support assembly 6 is perpendicular to the moving direction of the telescopic rod, so as to further improve the stability of the connecting passage of the attached lifting scaffold and the tower crane.

[0028] As shown in Figure 7 , the support plate 62 is further provided with a plurality of rotatable second rollers 63 which are arranged in a row on the support plate 62 and the arrangement direction of the second rollers 63 is consistent with the moving direction of the telescopic plate 2. The second rollers 63 are used to reduce the friction between the support plate 62 and the telescopic plate 2, so that the telescopic plate 2 moves more smoothly.

[0029] Please refer to Figure 3 , Figure 4 and Figure 6 , the guardrail assembly 4 further comprises a first box body 44 and a second box body 45. The first box body 44 is arranged on one side of the first fixed rod 41 close to the second fixed rod 42, the first fixed rod 41 is provided with a first seat body 47 for mounting the diamond-shaped telescopic rod, and the first box body 44 accommodates the connection between the diamond-shaped telescopic frame 43 and the first fixed rod 41. The second box body 45 is arranged on one side of the second fixed rod 42 close to the first fixed rod 41, the second fixed rod 42 is provided with a second seat body 48 for mounting the diamond-shaped telescopic rod, and the second box body 45 accommodates the connection between the diamond-shaped telescopic frame 43 and the second fixed rod 42. The opening of the first box body 44 is aligned with the opening of the second box body 45. After the attached lifting scaffold is moved and the telescopic plate 2 is retracted into the storage groove 11, the first box body 44 and the second box body 45 form a closed space for accommodating the diamond-shaped telescopic frame 43, so as to prevent the diamond-shaped telescopic frame 43 from being damaged by external force during the movement of the attached lifting scaffold. When the telescopic plate 2 is extended out of the storage groove 11, the first box body 44 and the second box body 45 respectively protect the connection between the diamond-shaped telescopic frame 43 and the first fixed rod 41 and the second fixed rod 42, so as to avoid the damage of the guardrail assembly 4 during the movement of the telescopic plate 2.

[0030] In detail, the guardrail assembly 4 further comprises a second telescopic rod 46, one end of which is connected with the first fixed rod 41 and the other end of which is fixedly connected with the second fixed rod 42, and the connection between the second telescopic rod 46 and the first fixed rod 41 is arranged at the end of the first fixed rod 41 away from the base plate 1, and the connection between the second telescopic rod 46 and the second fixed rod 42 is arranged at the end of the second fixed rod 42 away from the telescopic plate 2. When the telescopic plate 2 moves relative to the base plate 1, the second telescopic rod 46 is elongated or shortened along with the movement of the telescopic plate 2, and the second telescopic rod 46 can function as a guardrail to further reduce the risk of workers falling by accident during the passing process.

[0031] As shown in Figure 2 and Figure 4 , the telescopic plate 2 is further provided with a door plate 8 between the two second fixed rods 42, the door plate 8 is rotatably connected with one of the second fixed rods 42, and the other second fixed rod 42 is provided with a lock plate 81 matched with the door plate 8, by rotating the door plate 8, the connecting passage of the attached lifting scaffold and the tower crane can be opened or closed, and when the door plate 8 is rotated to the closed state, the door plate 8 and the lock plate 81 are locked by using a lock to keep the connecting passage of the attached lifting scaffold and the tower crane in the closed state, so as to prevent workers from walking in the connecting passage of the attached lifting scaffold and the tower crane during the movement of the telescopic plate 2.

[0032] Please refer to Figure 1 and 8 , in order to prevent the telescopic plate 2 from being damaged due to collision with the tower crane when the telescopic plate 2 is lapped with the tower crane, a buffer pad 7 is arranged on the side of the telescopic plate 2 away from the storage groove 11, the buffer pad 7 wraps part of the telescopic plate 2, the buffer pad is made of elastic material such as rubber to reduce the impact on the telescopic plate 2 and the tower crane when they collide, and the side of the buffer pad 7 away from the telescopic plate 2 has a round corner to facilitate the telescopic plate 2 to lap onto the tower crane.

[0033] As shown in Figure 1 and Figure 2As shown, the operation steps of connecting the attached lifting scaffold with the tower crane by the connecting channel of the attached lifting scaffold and the tower crane provided by the embodiment are as follows: after the attached lifting scaffold moves to the target position, the cylinder 51 is started to drive the first telescopic rod 52 to act to drive the rocker 32 to rotate, the rocker 32 pushes the sliding block 31 to act and drives the telescopic plate 2 to extend out of the storage groove 11 in the rotating process of the rocker 32, the cylinder 51 is closed after the end of the telescopic plate 2 away from the bottom plate 1 is overlapped with the tower crane, and the rhombus telescopic frame 43 and the second telescopic rod 46 are synchronously extended in the extending process of the telescopic plate 2, at this time, the worker walks to the telescopic plate 2 and opens the door plate 8 to connect the attached lifting scaffold with the tower crane; when the position of the attached lifting scaffold needs to be adjusted, the worker first closes the door plate 8 and moves to the bottom plate 1, then the first telescopic rod 52 is started to drive the first telescopic rod 52 to act to drive the rocker 32 to rotate, the rocker 32 pulls the sliding block 31 to act and drives the telescopic plate 2 to retract into the storage groove 11 in the rotating process of the rocker 32, the cylinder 51 is closed after the end of the telescopic plate 2 away from the bottom plate 1 is away from the tower crane, and the rhombus telescopic frame 43 and the second telescopic rod 46 are synchronously shortened in the retracting process of the telescopic plate 2, at this time, the telescopic plate 2 is separated from the tower crane to move the position of the attached lifting scaffold; after the movement of the attached lifting scaffold is completed, the cylinder 51 is started again and the above steps are repeated to reconnect the attached lifting scaffold with the tower crane.
