Description

Technical Field

[0001] The invention relates to the technical field of building construction devices, in particular to a material vertical transportation device. Background Art

[0002] During the construction process, it is usually necessary to transport construction materials to higher floor layers for construction on the higher floor layers. In the construction process of many high-rise buildings, construction material transportation is carried out by vertical hoisting, which hoists the materials from the bottom of the elevator shaft of the building to the corresponding floor layers. This vertical hoisting method has a higher hoisting efficiency.

[0003] For example, the anti-fall mechanism for vertical transportation of building materials disclosed in the Chinese utility model patent with authorization announcement date of 2015.02.04 and authorization announcement number of CN 204138073 U includes two support seats, a support member, a lifting bracket, an electric hoist installed on the top of the building for pulling the lifting bracket upward, and a winch installed on the lifting bracket for lifting materials. One end of the support member is hinged with the support seat, and the other end forms an insertion end. The lifting bracket includes a crossbeam and two vertical beams respectively fixed at both ends of the crossbeam. The side of the vertical beam away from the crossbeam is provided with slots arranged along the height direction. The slots are used to receive the insertion ends and have horizontal side walls that press the insertion ends downward. When the lifting bracket moves upward, the insertion ends are moved in the direction away from the vertical beams. Although the above technical solution can prevent falling to a certain extent, the lifting bracket can only move in one direction and has poor flexibility. Moreover, the anti-fall is to prevent the lifting bracket from falling. However, when the winch fails or the rope for lifting the material breaks, it still has no function to prevent the material from falling, and there are still major safety hazards.

[0004] For example, a Chinese utility model patent with an authorization announcement date of 2024.10.22 and an authorization announcement number of CN 221876506 U discloses a fall prevention device for mechanical safety, including a bracket and a protective device, a mobile frame is slidably connected to the surface of the bracket, a motor is fixedly connected to the surface of the bracket, the motor drives the mobile frame to rise and fall through a suspension rope, and the protective device is arranged on the surface of the mobile frame, and the protective device includes a clamping block, both sides of the mobile frame are provided with sliding holes, the clamping block is slidably connected to the inner wall of the sliding hole, the surface of the bracket is fixedly connected to a limit bar, and a spring is fixedly connected to the side of the clamping block corresponding to the inner wall of the sliding hole on the surface of the mobile frame. In this scheme, the mobile frame is pulled up by rotating the motor output shaft to wrap around the suspension rope, and the fall prevention of the mobile frame is achieved by the cooperation of the clamping block and the limit bar, and the clamping block and the limit bar are separated by manual operation, and the mobile frame is driven to descend under the action of gravity. Since the material on the mobile frame is heavy, once the clamping block and the limit bar are released, the mobile frame will drop rapidly, which will easily cause damage to the limit bar and cause the protective device to fail, posing a major safety hazard.

[0005] In summary, the existing vertical transportation devices for building materials have limited loading space, the anti-falling methods of the vertical transportation devices have safety hazards to varying degrees, and are inconvenient to use and have poor flexibility. Summary of the invention

[0006] In view of the deficiencies in the above-mentioned background technology, the present invention proposes a vertical material transportation device, which solves the technical problem that the existing vertical transportation device is prone to material falling and causing safety accidents.

[0007] The technical solution of this application is: A material vertical transport device comprises a car and a conveying mechanism, wherein the conveying mechanism comprises at least two transmission platforms with spiral grooves, each transmission platform is fixedly connected to the car, and a plurality of support rods are arranged along the vertical direction, and at least two support rods are engaged with the spiral grooves.

[0008] Preferably, both ends of the transmission platform are connected to the outer wall of the car through mounting seats.

[0009] Preferably, a slider is connected to the car, the support rod is arranged on a column, and the slider is slidably connected to the column.

[0010] Preferably, the column is connected to a support base, and the support base is telescopically connected to a universal wheel.

[0011] Preferably, the transmission platform is sleeved on a transmission rod, and the transmission rod is connected to the mounting seat.

[0012] Preferably, the transmission platform is connected to the drive motor via a reducer.

[0013] Preferably, two transmission platforms are provided, which are symmetrically connected to both sides of the car, a driving motor with a reducer is connected to the bottom of the car, the reducer is connected to a transfer shaft, and the transfer shaft is connected to the transmission rod through a gear set.

[0014] Preferably, two support bases are provided, and the two support bases are connected by a connecting rod.

[0015] Preferably, a traction assembly is provided on the top of the car, the traction assembly comprises a winding frame and a traction chain wound around the winding frame, and the winding frame is connected to an auxiliary motor.

[0016] Preferably, at least two traction assemblies are provided, and the traction assemblies are symmetrically distributed.

[0017] The technical solution disclosed in the present invention has the following beneficial effects: 1. The present invention achieves vertical transportation of materials by engaging the spiral groove of the transmission platform with the support rods arranged in the vertical direction, and using a driving motor to drive the spiral groove to rotate and then drive the car to climb along the support rods in the vertical direction. When the power is suddenly cut off, the transmission platform loses the power to rotate, while the support rods are still embedded in the spiral groove, ensuring that the car does not fall or drop, and playing an effective anti-falling effect, solving the technical problem that the existing vertical transportation device is prone to safety accidents caused by material falling; 2. The spiral groove of the present invention is engaged with multiple support rods at the same time, and the multiple support rods support the spiral groove and the supporting force is evenly distributed, which avoids the sudden increase of downward pressure on the car due to sudden power failure, and the support rods are damaged or overloaded, thereby improving the reliability of the anti-fall structure and the safety of vertical transportation; 3. When re-placing the materials to be transported, the rotation direction of the output shaft of the driving motor is changed, thereby changing the rotation direction of the transmission platform, changing the vertical movement direction of the spiral groove, and then driving the car to descend along the vertical support rod. Compared with the prior art in which the block and the limit bar are separated by manual operation and the mobile frame naturally descends under the action of gravity, this avoids the problem of damage to the limit bar due to the heavy materials on the mobile frame, and then causing the anti-falling structure to fail due to the rapid descent of the mobile frame after the block and the limit bar are released, thereby reducing the safety hazards of vertical transportation operations.

[0018] 4. By setting a telescopic rod on the support base to adjust the position of the universal wheel, when materials need to be transported, the universal wheel is retracted into the support base, thereby ensuring that the conveying mechanism is stable on the ground during material transportation and ensuring stable transportation. When the material transportation is completed or the position needs to be adjusted, the universal wheel is extended out of the support base to achieve rapid turnover of the vertical transportation device.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the core concept of the present invention and the following embodiments, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Embodiment 1, a material vertical transport device, such as Figure 1 As shown, it includes a car 4 and a conveying mechanism 2, the conveying mechanism 2 includes at least two transmission platforms 13 with spiral grooves 14, each transmission platform 13 is fixedly connected to the car 4, and multiple support rods 17 are arranged in the vertical direction, and at least two support rods 17 are embedded in the spiral grooves 14.

[0024] In this embodiment, the transmission platform 13 is cylindrical as a whole, and the spiral groove 14 is provided on the circumferential surface of the transmission platform 13. The transmission platform 13 can be connected to the car 4 through a "concave"-shaped bracket, the two ends of the transmission platform 13 are plugged into the two short sides of the bracket, the car 4 is connected to the middle of the bracket, and the spiral groove 14 is rotatably connected relative to the two short sides of the bracket. In other embodiments, the bracket can also be other shapes, as long as the transmission platform 13 can be connected to the car 4. No matter what shape the bracket is, after the transmission platform 13 is connected to the car 4, the spiral groove 14 is rotatably connected to the car 4.

[0025] Preferably, in order not to affect the carrying capacity of the car 4, the transmission platform 13 is rotatably connected to the outer wall of the car 4. When two transmission platforms 13 are connected to the outer wall of the car 4, the two transmission platforms 13 are symmetrically arranged on both sides of the car 4 to increase stability during vertical transportation; when there are three or more transmission platforms 13, the transmission platforms 13 are evenly arranged around the outer wall of the car 4, or multiple transmission platforms 13 are arranged on both sides of the car 4, which can further enhance the carrying capacity of the car 4.

[0026] Specifically, Figure 1 As shown, each support rod 17 is correspondingly arranged on the outside of the transmission platform 13, and a row of support rods 17 with equal intervals is a group. The number of groups of support rods 17 is the same as the number of transmission platforms 13. The support rod 17 is engaged with the spiral groove 14, and the transmission platform 13 is driven to rotate by the driving device, thereby driving the spiral groove 14 to rotate, thereby causing the spiral groove 14 to climb or descend along the support rod 17, so that the transmission platform 13 can rise or descend in the vertical direction. The transmission platform 13 is connected to the car 4, so when the transmission platform 13 moves in the vertical direction, it drives the car 4 to move, thereby realizing the vertical transportation of materials. The moving direction of the transmission platform 13 can be realized by changing the rotation direction of the spiral groove 14, thereby changing the moving direction of the car 4.

[0027] Specifically, Figure 1 As shown, vertical transportation is achieved by rotating the transmission platform 13. When the power is suddenly cut off, the transmission platform 13 stops rotating. Since the support rod 17 is embedded in the spiral groove 14, it is ensured that the car 4 does not fall or drop, and an effective anti-falling effect is achieved. The spiral groove 14 is simultaneously engaged with multiple support rods 17 to increase the contact area. Multiple support rods 17 are embedded in the spiral groove 14 to form a support with uniformly distributed support force, which avoids damage or overload of the support rods 17, improves the reliability of the anti-falling structure, and improves the safety of vertical transportation.

[0028] In addition, in order to improve the stability during vertical transportation, such as Figure 5 As shown, a rotatable supporting wheel 18 is provided at the end of the support rod 17, and the supporting wheel 18 is embedded in the spiral groove 14, which effectively prevents the car 4 from falling when the power is off, ensuring safe operation. Multiple supporting wheels 18 are embedded in the spiral groove 14 to form a support, and the supporting force is evenly distributed, which prevents the supporting wheel 18 from being damaged or overloaded, and the supporting wheel 18 can rotate when in contact with the spiral groove 14, reducing the friction between the spiral groove 14 and the supporting wheel 18, so that the vertical movement of the car 4 is smoother.

[0029] Embodiment 2, based on embodiment 1, a material vertical transportation device, such as Figures 1 to 3 As shown, the transmission platform 13 is connected to the outer wall of the car 4 through the mounting seat 12. Specifically, one transmission platform 13 matches two mounting seats 12, and the two mounting seats 12 are respectively connected to the two ends of the transmission platform 13. By setting a circular hole in the center of the mounting seat 12, inserting the two ends of the transmission platform 13 into the circular holes of the two mounting seats 12, the rotation connection between the transmission platform 13 and the mounting seat 12 can be realized, and then the mounting seat 12 is fixedly connected to the outer wall of the car 4, the rotation connection of the transmission platform 13 relative to the outer wall of the car 4 can be realized.

[0030] Embodiment 3, based on embodiment 2, a material vertical transportation device, such as Figures 1 to 3As shown, the car 4 is connected with a slider 15, the support rod 17 is arranged on the column 16, and the slider 15 is slidably connected with the column 16. Specifically, a group of support rods 17 matches one column 16, and one column 16 matches two sliders 15, and the slider 15 is used to reduce the shaking of the car 4 during vertical transportation and improve the stability of the car 4 during vertical transportation. Preferably, the distance between the two sliders 15 is greater than the length of the transmission platform 13, and the two sliders 15 are located between the two mounting seats 12. One side of the slider 15 is fixedly connected to the side wall of the car 4, and a receiving groove is opened in the center of the slider 15. The column 16, the support rod 17 and the supporting wheel 18 all pass through the receiving groove of the slider 15. The slider 15 only contacts with the column 16, and there is no contact between the slider 15 and the support rod 17, the slider 15 and the supporting wheel 18, and the slider 15 and the transmission platform 13. The slider 15 slides relative to the column 16 and the transmission platform 13 in the vertical direction.

[0031] Embodiment 4, based on embodiment 3, a material vertical transportation device, such as Figures 1 to 3 As shown, the column 16 is connected to the support base 1, and the support base 1 is telescopically connected to the universal wheel 24. Specifically, one column 16 matches one support base 1. In this embodiment, the support base 1 is a rectangular box, and a mounting groove 102 is opened on the rectangular box. A telescopic rod 23 is connected in the mounting groove 102, and the universal wheel 24 extends out of the mounting groove 102 or shrinks in the mounting groove 102 through the telescopic rod 23. It is convenient to move to different positions for hoisting, and increases the stability of vertical transportation when it does not need to be moved.

[0032] Embodiment 5, based on embodiment 4, a material vertical transportation device, such as Figures 1 to 3 As shown, the transmission platform 13 is sleeved on the transmission rod 11, and the transmission rod 11 is connected to the mounting seat 12. In this embodiment, the transmission platform 13 can be fixedly connected to the middle part of the transmission rod 11, or can be detachably connected to the middle part of the transmission rod 11, and both ends of the transmission rod 11 are connected to the mounting seat 12, and the transmission rod 11 is rotatably connected to the mounting seat 12. The transmission platform 13 is driven to rotate by rotating the transmission rod 11, and then the spiral groove 14 on the transmission platform 13 cooperates with the supporting wheel 18 on the support rod 17, so that the transmission platform 13 moves along the vertical direction. When the transmission platform 13 is detachably connected to the middle part of the transmission rod 11, the moving direction of the car 4 can be adjusted by changing the rotation direction of the transmission rod 11, and the moving direction of the car 4 can be adjusted by installing the transmission platform 13 upside down. Further, the transmission rod 11 passes through the receiving groove of the slider 15, and the transmission rod 11 does not contact the slider 15. The supporting wheel 18 is arranged at the end of the support rod 17 away from the column 16.

[0033] Embodiment 6, based on any one of Embodiments 1-5, a material vertical transportation device, wherein the transmission platform 13 is connected to the drive motor 8 through a reducer 9. Specifically, one transmission platform 13 matches one drive motor 8, so that the central axis of the output shaft of the drive motor 8 coincides with the axis of the transmission platform 13. To protect the drive motor 8, a reducer 9 is provided between the output shaft of the drive motor 8 and the transmission platform 13. The reducer 9 can reduce the rotation speed of the transmission platform 13 and increase the torque, so that the car 4 moves slowly in the vertical direction, prevents the material from falling, and improves the safety of vertical transportation.

[0034] During specific implementation, the spiral groove 14 is set in the middle of the transmission platform 13, the diameter of the upper end of the transmission platform 13 is reduced, the upper end of the transmission platform 13 is rotatably matched with the circular hole of the mounting seat 12 located above, the diameter of the lower end of the transmission platform 13 is reduced and passed through the mounting seat 12 to connect with the reducer 9, the lower end of the transmission platform 13 is connected to the output end of the reducer 9, and the input end of the reducer 9 is connected to the output shaft of the drive motor 8.

[0035] In this embodiment, the transmission rod 11 and the transmission platform 13 together constitute the driven component 6, the column 16 and the support rod 17 together constitute the fixed component 7, the spiral groove 14 of the transmission platform 13 is engaged with the support rod 17 of the fixed component 7, and the spiral groove 14 rotates under the drive of the drive motor 8 and drives the transmission platform 13 to move in the vertical direction.

[0036] Embodiment 7, based on embodiment 5, a material vertical transportation device, such as Figure 2 and Figure 3 As shown, there are two transmission platforms 13, which are symmetrically connected to both sides of the car 4. A driving motor 8 with a reducer 9 is connected to the bottom of the car 4. The reducer 9 is connected to a transfer shaft 10, and the transfer shaft 10 is connected to a transmission rod 11 through a gear set. In this embodiment, there are two transmission platforms 13 and two transmission rods 11, which are symmetrically arranged on both sides of the car 4. A bevel gear is arranged at the lower end of the transmission rod 11. The driving motor 8, the reducer 9 and the adapter shaft 10 together constitute a driving assembly 5. Gears matching the bevel gear are arranged at both ends of the adapter shaft 10. The adapter shaft 10 is driven to rotate by the driving motor 8 and the reducer 9, and the bevel gear at the lower end of the transmission rod 11 is driven to rotate by the gears at both ends of the adapter shaft 10, thereby driving the transmission rod 11 and the transmission platform 13 to rotate. Since the rotation directions of the two transmission platforms 13 are opposite, the rotation directions of the spiral grooves 14 on the two transmission platforms 13 should be set in opposite directions to ensure that the movement directions of the two transmission platforms 13 in the vertical direction are consistent.

[0037] Embodiment 8, based on embodiment 7, a material vertical transportation device, such as Figures 1 to 3As shown, the support base 1 is provided with two, and the two support bases 1 are connected by a connecting rod 25. In order to facilitate moving to different positions for hoisting, the two support bases 1 are connected together. Specifically, a reserved hole 101 is provided on the top of the support base 1, and a U-shaped connecting rod 25 is provided between the two reserved holes 101. One end of the connecting rod 25 is inserted into one of the reserved holes 101, and the other end of the connecting rod 25 is inserted into the other reserved hole 101.

[0038] Embodiment 9, based on embodiment 8, a material vertical transportation device, such as Figures 1 to 4 As shown, a traction assembly 3 is provided on the top of the car, and the traction assembly 3 includes a winding frame 20 and a traction chain 21 wound on the winding frame 20, and the winding frame 20 is connected to an auxiliary motor 19. In order to expand the specifications of the transported materials, adapt to materials of different shapes and reduce the risk of materials slipping from the car 4, the traction assembly 3 includes an auxiliary motor 19, the auxiliary motor 19 is connected to the winding frame 20, and the traction chain 21 is wound on the winding frame 20, and the end of the traction chain 21 is connected to a hook 22 for hanging materials. Specifically, the auxiliary motor 19 is fixedly connected to the top of the car 4, and the winding frame 20 is in a sideways I-shaped shape, and the center of the I-shaped shape is connected to the output shaft of the auxiliary motor 19.

[0039] Embodiment 10, based on embodiment 9, a material vertical transportation device, such as Figure 1 As shown, at least two traction assemblies 3 are provided, and each traction assemblies 3 is symmetrically distributed. The symmetrical arrangement of the traction assemblies 3 helps to improve the stability of the car 4 during transportation in the vertical direction, and further reduces the risk of materials sliding off the car 4.

[0040] When implementing Example 10, first extend the telescopic rod 23 to expose the universal wheel 24 from the support base 1, move the vertical transport device to an appropriate position, and then retract the telescopic rod 23 to store the universal wheel 24 in the installation groove 102 of the support base 1, so that the support base 1 is placed stably to ensure that the vertical transport device can be used stably.

[0041] Next, the materials to be transported are placed on the car 4. When the materials are long or of large specifications, the hook 22 is used to hook the materials. The auxiliary motor 19 starts to run and the traction chain 21 is reeled in to assist in traction of the materials to maintain the balance of the materials. Then the drive motor 8 at the bottom of the car 4 starts to run. The power provided by the drive motor 8 is transmitted to the transfer shaft 10 through the speed reducer 9. The transfer shaft 10 starts to rotate, and then the transmission platform 13 on the transmission rod 11 is driven to rotate under the meshing action of the gear set at the end of the transfer shaft 10, and then the spiral groove 14 on the transmission platform 13 rotates. The spiral groove 14 is engaged with the supporting wheel 18 on the column 16, so that the spiral groove 14 climbs synchronously along the column 16 when rotating to realize vertical transportation of materials. When the car 4 needs to fall and the materials to be transported need to be replaced, the rotation direction of the output shaft of the drive motor 8 can be changed.

[0042] When the power is suddenly cut off, the spiral groove 14 loses the power to rotate, while the supporting wheel 18 is still embedded in the spiral groove 14, ensuring that the car 4 does not fall or drop, and playing an effective anti-falling effect. In addition, the spiral groove 14 is engaged with multiple support rods 17 at the same time, increasing the contact area. Multiple support rods 17 are embedded in the spiral groove 14 to form a support with uniformly distributed support force, avoiding damage or overload of the support rods 17, improving the reliability of the anti-falling structure, and improving the safety of vertical transportation.

[0043] When the material transportation is completed, the telescopic rod 23 is extended again to expose the universal wheel 24 from the support base 1, and the vertical transportation device is removed. The above is the use process of the material vertical transportation device.

[0044] The details not described in detail in the present invention are all conventional technical means known to those skilled in the art.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
