Description

Technical Field

[0001] This invention relates to the field of lifting and transporting equipment technology, and in particular to a construction lifting device. Background Technology

[0002] Existing construction hoisting equipment involves using a drive system to lift and lower a hoisting device, such as a cage assembly, on a standard section to transport materials to a predetermined floor of a building. Since the standard section is typically connected to the building surface, the cage assembly can be positioned on the side of the standard section away from the building. When it is necessary to transfer the transported materials from the cage assembly to the floor, a platform needs to be erected between the cage assembly and the floor to facilitate material transport. However, because the cage assembly is located on the side of the track assembly away from the floor, the distance between the cage assembly and the floor is relatively long, requiring a considerable amount of time to construct the passageway, and the constructed passageway lacks stability.

[0022] To facilitate worker access between the building and the hoisting cage, existing construction hoisting equipment typically places the hoisting cage next to the track assembly. This allows workers to move between the building and the hoisting cage without having to walk around the track assembly, reducing the distance traveled at height. When the building's exterior wall has a significant angle of inclination, the track assembly is fixed to the exterior wall for good stability. However, when the hoisting cage is placed next to the track assembly, the track assembly is subjected to force from the hoisting cage on one side, which can easily lead to uneven stress and deformation. To address this, the hoisting cage is repositioned on the side of the track assembly away from the building. The inclined track assembly supports the weight of the hoisting cage along the vertical track, thus distributing the force through the building and reducing the component of the hoisting cage's weight along the length of the track assembly, thereby reducing deformation. However, this results in a longer distance between the hoisting cage and the building, requiring a longer time to construct the access path, and the constructed path may lack stability.

[0023] Therefore, this application provides a construction lifting device, referring to Figure 1 and Figure 2 It includes: The track assembly 2 is connected to an external building on one side. Specifically, multiple sets of support rods are arranged along the length of the track assembly 2. The other end of the support rods away from the track assembly 2 is connected to the exterior wall of the building. The front side of the track assembly 2 is inclined toward the building. The hoisting cage assembly 1 includes a main cage 11 and a side cage 12. The main cage 11 is connected to the rear side of the track assembly 2, and the side cage 12 is connected to the main cage 11. The side cage 12 is located on one side of the main cage 11 in the left-right direction. The front side of the side cage 12 extends in the direction close to the building and passes over the track assembly 2. A cargo opening is provided on the front side of the side cage 12. A flip door 13 is rotatably installed on the side cage 12 at the cargo opening. The flip door 13 can be flipped on the side cage 12 to overlap the building. Drive component 3, which is used to drive the cage assembly 1 to move on the track assembly 2.

[0024] As described above, firstly, the main cage 11 for storing materials is positioned on the side of the track assembly 2 away from the building, and the side of the track assembly 2 away from the main cage 11 is connected to the building to ensure good installation stability of the track assembly 2. Subsequently, a side cage 12 is installed on the side of the main cage 11 closest to the building. After the side cage 12 passes over the track assembly 2, the distance between the main cage 11 and the building is shortened. A loading port and a flap door 13 are installed on the side cage 12, allowing the flap door 13 to be erected on the predetermined floor of the building after opening, enabling construction workers to walk directly into the building through the flap door 13. This design utilizes the side cage 12 to reduce the distance between the entire hoisting cage assembly 1 and the floor, and makes full use of the main cage 11 and the track assembly. The space between the two is used to set up the side cage 12. At the same time, the side cage 12 can be used for walking and placing materials, thereby further improving the utilization rate of the cage assembly 1. In addition, the side cage 12 provides a load-bearing foundation for the flip door 13, reducing the distance that workers walk on the suspended platform and further improving the safety factor of construction. In addition, when the building floor is inclined, the track assembly 2 can be directly erected on the building exterior wall. At this time, the cage assembly 1 is located on the side of the track assembly 2 away from the building exterior wall. When the track assembly 2 is inclined, the weight of the cage assembly 1 includes a first component along the length direction of the track assembly 2 and a second component along the length direction perpendicular to the length direction of the track assembly 2. The building can bear the second component of the cage assembly 1 along the length direction perpendicular to the length direction of the track assembly 2.

[0025] Furthermore, the main cage 11 extends in the left-right direction, and the length of the main cage 11 is greater than the length of the track assembly 2 in the left-right direction. The main cage 11 is provided with side cages 12 on both the left and right sides. The two side cages 12 have the same structure and are connected to the main cage 11. By providing two side cages 12, the internal space of the entire hoisting cage assembly 1 can be greatly improved. At the same time, workers can enter and exit the hoisting cage assembly 1 from both sides, thereby improving the handling efficiency of goods in the hoisting cage assembly 1.

[0026] If only the two side cages 12 are connected to the main cage 11, the two sides of the main cage 11 will have to bear the weight of the two side cages 12, which may cause deformation at both ends of the main cage 11. Therefore, refer to Figure 1 and Figure 2 An installation space is formed between the first side cage 12, the main cage 11 and the second side cage 12. The track assembly 2 passes through the installation space. The drive assembly 3 is slidably installed on one side of the main cage 11 and connected to the track assembly 2 on the other side.

[0027] As can be seen from the above, the main cage 11 and the two side cages 12 surround the track assembly 2, thereby reducing the risk of the track assembly 2 detaching from the installation space, and increasing the contact space between the cage assembly 1 and the track assembly 2, which makes it easier to add a reinforcing structure between the two and provides spatial convenience.

[0028] Since the two side cages 12 have the same structure, the following embodiments will be described using the right side cage 12 as an example. For better sealing of the cargo opening, refer to... Figure 3 and Figure 4 The bottom side of the flap door 13 is rotatably installed on the bottom side of the side cage 12 at the cargo opening, and the side cage 12 is slidably installed with a sliding door 14 in the vertical direction on the top side of the cargo opening.

[0029] In order to quickly open the sliding door 14 and reduce the time for workers to manually open the loading port, the flap door 13 and the sliding door 14 are connected by a pull rope 121. Workers can pull the pull rope 121 to simultaneously open or close the flap door 13 and the sliding door 14, which improves work efficiency.

[0030] Specifically, in this embodiment, the end of the flap door 13 away from its rotatable connection with the side cage 12 is a free end, and one end of the pull rope 121 is connected to the free end of the flap door 13. The free end is preferably the very end of the flap door 13 away from the rotatable connection. A first pulley 122 is provided on the top of the side cage 12. The first pulley 122 and the pull rope 121 are both on the vertical surface of the right side wall of the side cage 12. The end of the pull rope 121 away from the flap door 13 is wrapped around the first pulley 122 and extends downward and is connected to the bottom side of the sliding door 14.

[0031] As described above, when the hoist cage assembly 1 moves to the predetermined position, the flip door 13 is flipped from the cargo port, so that the free end moves to the building ground. When the flip door 13 is flipped on the side cage 12 and erected on the floor, it drives one end of the pull rope 121 to move away from the side cage 12, thereby shortening the length of the pull rope 121 wrapped around the other side of the first pulley 122. Since the length direction of the pull rope 121 on the other side of the first pulley 122 is parallel to the movement direction of the sliding door 14, the pull rope 121 can drive the sliding door 14 to be lifted vertically, thereby fully opening the sliding door 14. First, the cargo port is completely closed by the sliding door 14 and the flip door 13, improving the safety factor when closing the door. Second, when the flip door 13 is opened, the sliding door 14 is extended upward synchronously by the linkage of the pull rope 121, reducing the step of manually pulling open the sliding door 14 and speeding up the construction speed.

[0032] To fully transfer the force of the flip door 13 to the sliding door 14, a connecting block is provided at the bottom of the sliding door 14. The connecting block is located directly below the first pulley 122. One end of the pull rope 121 extends vertically downwards around the first pulley 122 and is connected to the connecting block. After the connecting block is extended to directly below the pull rope 121 at the first pulley 122, the pull rope 121 passes around the first pulley 122 and is connected to the connecting block, thus restricting the vertical extension of the pull rope 121. When the flip door 13 flips and moves the end of the pull rope 121 away from the connecting block, the direction of movement of the end of the pull rope 121 away from the flip door 13 and the opening and closing direction of the sliding door 14 are both vertical, reducing the angle between the two directions of movement and greatly saving the force required for the pull rope 121 to move the sliding door 14.

[0033] Furthermore, because after the cage assembly 1 moves to the predetermined floor on the track assembly 2, the flip door 13 drives the sliding door 14 to rise via the pull rope 121. When the cage assembly 1 and the predetermined floor are not on the same horizontal plane, the flip door 13 cannot be completely horizontal when it flips over and is placed on the floor. This prevents the flip door 13 from rotating to the predetermined angle, and consequently, it cannot fully open the sliding door 14 via the pull rope 121. The sliding door 14 will then block the loading port, preventing large items from passing through. Therefore, referring to... Figure 3 and Figure 4 The side cage 12 is provided with a second pulley 123 below the first pulley 122. The second pulley 123 can move along the side wall of the side cage 12 in a direction parallel to the horizontal. The pull rope 121 first passes around the second pulley 123 and then passes around the first pulley 122.

[0034] Specifically, a translation drive 124 is provided on the side wall of the side cage 12. The output end of the translation drive 124 is connected to the second pulley 123. In this embodiment, the translation drive 124 can be any linear drive mechanism, and this application embodiment does not specifically limit it.

[0035] Furthermore, the translation drive 124 and the second pulley 123 are arranged sequentially from back to front, such that the pull rope 121 extends from the flip door 13, passes between the second pulley 123 and the translation drive 124, and then wraps around the first pulley 122. The second pulley 123, the first pulley 122, and the flip door 13 are arranged sequentially from back to front, that is, after the translation drive 124 drives the second pulley 123 to move backward or backward, it drives the pull rope 121 wrapped around the second pulley 123 to move.

[0036] As described above, when the above situation occurs, the second pulley 123 is driven to move on the side cage 12, thereby causing the pull rope 121 to move laterally in the segment between the first pulley 122 and the flap door 13. When the plane where the bottom of the cage assembly 1 is located is higher than the predetermined floor plane, the end of the flap door 13 away from the side cage 12 tilts downward under its own weight, which may cause the pull rope 121 to tighten the sliding door 14, causing the sliding door 14 to be subjected to excessive force and collide with the side cage 12. At this time, the second pulley 123 is driven to move horizontally. The upper part moves towards the flip door 13, thereby loosening the pull rope 121 towards the first pulley 122. When the plane where the bottom of the cage assembly 1 is located is lower than the predetermined floor plane, the end of the flip door 13 away from the side cage 12 is lifted by the predetermined floor ground to tilt upward. At this time, the second pulley 123 is driven to move horizontally away from the flip door 13, tightening the pull rope 121 away from the first pulley 122, thereby raising the sliding door 14 to the predetermined height, so that the cargo opening is fully opened.

[0037] The movable second pulley 123 drives the pull rope 121 to be tensioned, thereby reducing the incomplete opening and closing of the sliding door 14 caused by the misalignment between the cage assembly 1 and the predetermined floor, so that the cargo opening can be fully opened, and reducing the impact caused by the sliding door 14 moving beyond the limit due to the excessive flipping of the flip door 13.

[0038] In this application, reference is made to Figure 3 , Figure 5 and Figure 6 The drive assembly 3 includes a connecting frame 31 and a power source 32. The power source 32 is mounted on the connecting frame 31. The front side of the connecting frame 31 is connected to the track assembly 2. The power source 32 is used to drive the connecting frame 31 to move on the track assembly 2. The connecting frame 31 is provided with a rod group, which includes a first connecting rod 33 and a second connecting rod 34. One end of the first connecting rod 33 is connected to the rear top of the connecting frame 31, and the other end extends rearward and connects to the main cage 11. An inclined wire is connected between the two first connecting rods 33. The second connecting rod 34 is connected at one end to the bottom rear side of the connecting frame 31 and at the other end to the main cage 11 with an upward inclination. A cross brace 35 is connected between the first connecting rods 33 of the two rod groups. The two ends of the cross brace 35 are respectively connected to the two side cages 12. The first connecting rod 33 and the second connecting rod 34 are used to make the connecting frame 31 and the main cage 11 stably connected. The cross brace 35 is then used to fix the connecting frame 31 to the two side cages 12, thereby improving the connection strength of the connecting frame 31, the main cage 11 and the side cages 12.

[0039] Specifically, the power source 32 includes a power motor and a power gear. The power motor is fixedly installed on the connecting frame 31, and the power gear is sleeved on the output end of the power motor. The output end of the power motor extends in a direction perpendicular to the length of the track assembly 2. The track assembly 2 includes a conveying track and a power rack 21. The power rack 21 is installed on the conveying track and extends along the length of the conveying track. The connecting frame 31 is installed on the conveying track, and the power gear meshes with the power rack 21. Furthermore, the connecting frame 31 has at least two clamping wheels on the side of the power rack 21 away from the power gear. The two adjacent clamping wheels correspond to the power gear, and the projection of the power gear on the straight line of the length of the power rack 21 is located between the projections of the two clamping wheels on the straight line of the length of the power rack 21. The two adjacent clamping wheels clamp the power rack 21, so that the power rack 21 is pressed against the power gear. The connecting frame 31 is used to connect the main cage 11 and the two side cages 12 at the same time, which improves the connection strength between the track assembly 2 and the cage assembly 1.

[0040] Because the pull rope 121 is exposed to the external environment and needs to roll and rub against the first pulley 122 and the second pulley 123 multiple times, after long-term use, the pull rope 121 may wear out excessively and break, eventually causing the sliding door to fall under its own weight. Therefore, in order to reduce the risk of the sliding door 14 falling due to the pull rope 121 breaking after wear, the sliding door 14 is further secured after sliding into place, as shown in the following figure. Figure 7 and Figure 8 The side cage 12 has an installation cavity 4 extending vertically along its inner wall in the left-right direction. The sliding door 14 slides within the installation cavity 4 along one side in the left-right direction. The inner wall of the installation cavity 4 away from the sliding door is connected to a clamping installation groove 5. Two clamping blocks 51 are rotatably installed in the clamping installation groove 5. The two clamping blocks 51 are symmetrically arranged in the clamping installation groove 5 along a straight line in the left-right direction. The end of the clamping block 51 near the sliding door 14 extends into the installation cavity 4. A clamping space is formed between the ends of the two clamping blocks 51 extending into the installation cavity 4. The sliding door 14 can move vertically along the direction of entering and exiting the clamping space. The side cage 12 is provided with a driving assembly 6 for driving the two clamping blocks 51 to rotate within the side cage 12.

[0041] After the hoisting cage assembly 1 moves to the predetermined floor of the building, the sliding door 14 is opened by the linkage of the flip door 13 and the pull rope 121. After the sliding door 14 moves into place, the drive assembly 6 is activated to drive the two clamping blocks 51 to rotate in the clamping mounting groove 5 until the two clamping blocks 51 clamp the sliding door 14 located in the clamping space, thereby stabilizing the sliding door 14 and reducing the risk of the sliding door 14 falling from there.

[0042] Reference Figure 8 and Figure 9In this embodiment, the driving assembly 6 includes a belt 61, pulleys 62, and a rotary drive member 67. The side cage 12 has a driving groove extending vertically. The pulleys 62 are rotatably mounted at both ends of the driving groove. The rotary drive member 67 drives one of the pulleys 62 to rotate. The axis of rotation of the pulleys 62 extends horizontally. The belt 61 is wound around the two pulleys 62. A first driving block 63 is provided on each pulley 62. The first driving block 63 can move upwards with the belt 61. Furthermore, the driving groove extends along the length of the belt 61 to fix the movement path of the first driving block 63. The drive groove is connected to the mounting cavity 4 through the clamping mounting groove 5, so that one end of the clamping block 51 extends into the drive groove and the other end extends into the mounting cavity 4. The ends of the two clamping blocks 51 away from the sliding door 14 both extend into the drive groove. The sides of the two clamping blocks 51 that extend into the drive groove and are close to each other are located on the sliding path of the first drive block 63. That is, when the first drive block 63 moves with the belt 61, it can be inserted between the two ends of the two clamping blocks 51 located in the clamping mounting groove 5. The drive assembly 6 also includes a first reset member 64 that rotates the ends of the two clamping blocks 51 that extend into the drive groove in a direction away from each other.

[0043] When the sliding door 14 comes to a stop, the rotary drive 67 drives the belt 61 to rotate via the pulley 62. During this process, the first drive block 63 rises continuously with the belt 61 until it moves between the two ends of the two clamping blocks 51 in the clamping mounting groove 5. This pushes open the ends of the two clamping blocks 51 in the clamping mounting groove 5, causing one end of the two clamping blocks 51 in the clamping mounting groove 5 to rotate horizontally away from each other. This causes the ends of the two clamping blocks 51 that extend into the mounting cavity 4 to rotate towards each other, thereby clamping the sliding door 14 and reducing the risk of the sliding door 14 falling.

[0044] To improve the stability of the sliding door 14 after it comes to rest, clamping slots 141 are provided on the side walls of the sliding door 14 along the front and rear directions. The clamping slots 141 correspond one-to-one with the clamping blocks 51. After the clamping blocks 51 are rotated, they can be engaged in the corresponding clamping slots 141.

[0045] Furthermore, in order to enable the first driving block 63 to drive the two clamping blocks 51 more smoothly, guide surfaces 631 are provided on both opposite sides of the first driving block 63. The distance between the two guide surfaces 631 gradually decreases in the direction that gradually moves away from the body of the first driving block 63. The two guide surfaces 631 are respectively located on the movement path of one end of the two clamping blocks 51 that extends into the driving groove. Through the guide surfaces 631, the first driving block 63 can smoothly slide between the two clamping blocks 51.

[0046] Reference Figure 7 In this embodiment, the first reset member 64 is a spring, and one first reset member 64 corresponds to one clamping block 51. One end of the first reset member 64 is installed on the groove wall of the clamping mounting groove 5, and the other end is connected to the end of the corresponding clamping block 51 that extends into the clamping mounting groove 5. When the two first reset members 64 are in their natural state, they can drive the ends of the two clamping blocks 51 that extend into the clamping mounting groove 5 to rotate toward each other, so that the ends of the two clamping blocks 51 that extend into the mounting cavity 4 move away from each other, thereby opening the clamping space so that the sliding door 14 can slide smoothly.

[0047] Furthermore, referring to Figure 5 , Figure 8 and Figure 10 In this embodiment, a locking groove 311 is provided on the connecting frame 31, and a locking rod 3111 is slidably installed in the locking groove 311. A locking hole 22 is provided on the standard section of the track assembly at each floor position. When the cage assembly moves to the predetermined floor of the building, after opening the flip door 13 and the sliding door 14, the cage assembly 1 and the connecting frame 31 and the track assembly are in a relatively stationary state. The locking rod 3111 can slide from the locking groove 311 until the locking rod 3111 partially enters the locking hole 22 corresponding to the floor, thereby locking the relatively stationary cage assembly 1, the connecting frame 31 and the track assembly 2 through the locking rod 3111, improving the stability of the entire cage assembly 1 at the predetermined position of the building.

[0048] To drive the locking rod 3111 to move, a sliding hole 125 extending in the left-right direction is provided on the bottom of the side cage 12 near the connecting frame 31. A second driving block 66 is also provided on the other segment of the belt 61 opposite to the first driving block 63. The locking groove 311 is connected to the driving groove through the sliding hole 125. The locking rod 3111 can pass through the sliding hole 125 and into the driving groove. The opening of the sliding hole 125 near the driving groove is located on the moving path of the second driving block 66. When the rotating drive member 67 drives the belt 61 to rotate through the pulley 62, the first… The second drive block 66 moves downward with the belt 61 until it abuts against the locking rod 3111 that is inserted into the drive groove. The second drive block 66 is provided with a drive surface, which abuts against the locking rod 3111, thereby driving the locking rod 3111 to move and insert into the locking hole 22 of the track assembly 2. This driving method uses two segments of the belt 61 that move in opposite directions to drive the first drive block 63 to move and simultaneously drive the second drive block 66 to move, so that while clamping the sliding door 14, the locking rod 3111 is driven to move into the locking hole 22.

[0049] In order to drive the locking rod 3111 back into the locking groove 311, thereby returning the cage assembly to the moving state, a second reset member is provided in the locking groove 311. In this embodiment, the second reset member 65 is an elastic member. One end of the second reset member 65 is sleeved on the locking rod 3111 and the other end is installed on the groove wall of the locking groove 311. When the second drive block leaves and no longer abuts against the locking rod 3111, the second reset member 65 elastically resets and drives the locking rod 3111 back into the locking groove 311 until the second reset member 65 is in the natural state.

[0050] To further limit the risk of the sliding door 14 falling again during material transportation after it is raised and the loading port is opened, refer to Figure 4 and Figure 11 In this embodiment, a mounting block 7 is provided on the side wall of the side cage 12. The mounting block 7 has a stabilizing cavity 71 extending in the vertical direction. One end of the pull rope 121 passes around the first pulley 122, passes through the stabilizing cavity 71, and is connected to the sliding door 14. A stabilizing groove 72 is provided on the inner wall of the stabilizing cavity 71. A stabilizing wheel 73 is elastically connected in the stabilizing groove 72. Specifically, an elastic element can be provided at the bottom of the stabilizing groove 72, and the stabilizing wheel 73 can be connected to the end of the elastic element away from the bottom of the groove. A stabilizing block 74 is provided on the pull rope 121. The stabilizing block 74 can move into the stabilizing cavity 71 with the pull rope 121. When the sliding door 14 moves to the top side of the side cage 12, the stabilizing block 74 can move above the stabilizing wheel 73 and abut against the stabilizing wheel 73.

[0051] When the sliding door 14 moves upward to the end, the stabilizing block 74 passes through the two stabilizing wheels 73. Under the elastic connection of the stabilizing wheels 73 in the stabilizing groove 72, the stabilizing wheels 73 are driven to move away from the bottom of the stabilizing groove 72 and lift the stabilizing block 74 from below. At this time, under the weight of the flip door 13 and the lifting of the stabilizing wheels 73, the sliding door 14 is stabilized in the open state by the pull rope 121, which reduces the risk of the sliding door 14 falling downward and causing an accident when the construction lifting equipment is running. At the same time, it can reduce the relative displacement of the transmission gears and transmission racks on the sliding door 14, thereby improving the stability of the clamping block 51 clamping the track assembly 2.

[0052] Furthermore, the pull rope 121 is equipped with a guide wheel on the stabilizing block 74, which allows the stabilizing block 74 to roll into the stabilizing cavity 71, reducing resistance.
