Description

Technical Field

[0001] This utility model relates to the field of construction hoist technology, specifically a construction hoist that stops on time. Background Technology

[0002] Construction hoists are vertical transportation equipment used on construction sites. They move up and down along guide rails in a cage, carrying people and goods. They play an important role in the efficient and convenient vertical transportation of personnel and materials in construction projects.

[0003] Common construction hoists typically use a base cage to support the hoist's guide rail frame, which is used for the cage's vertical movement. Wall-mounted frames ensure the stability of the guide rail frame as it is continuously erected and raised.

[0004] However, since elevators generally use gears and racks for lifting, and the gears rotate too fast, they cannot accurately lift the elevator to the designated floor. As a result, when the construction elevator cannot stop at the designated floor on time, people may fall because they are in a hurry to get on or off the vehicle before reaching or after missing the target floor. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a construction hoist that stops on time, thereby solving the problem mentioned in the background art where the gears rotate too fast and cannot accurately lift the hoist to the designated floor. This leads to the possibility of people falling into the hoist while rushing to get on or off before reaching or having missed the target floor.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a construction hoist that stops on time, comprising:

[0009] A bottom cage, wherein a guide rail frame is mounted on the upper surface of the bottom cage, and racks are mounted on both sides of the front of the guide rail frame;

[0010] A cage is mounted on the surface of a guide rail frame. A first motor is mounted on the back of the cage. A first gear is coaxially mounted on the rotor of the first motor. A second gear is mounted on the surface of the first gear via a connecting rod. Both the first gear and the second gear mesh with the surface of a rack.

[0011] A mounting plate is disposed on the upper surface of the guide rail frame. A second motor is mounted on the inner wall of the mounting plate. A third gear is mounted on the rotor output end of the second motor. A first driven wheel is mounted on the surface of the third gear. A fourth gear meshes with the surface of the first driven wheel. A second driven wheel is mounted on the surface of the fourth gear. A fifth gear meshes with the surface of the second driven wheel. A take-up roller meshes with the surface of the fifth gear. A lifting rope is wound around the surface of the take-up roller. The bottom end of the lifting rope is connected to the upper surface of the cage.

[0012] Preferably, the back of the guide rail frame is provided with a wall-mounted bracket, and the four corners of the surface of the wall-mounted bracket are connected to the surface of the guide rail frame through connecting blocks, so that the guide rail frame can be installed on the wall.

[0013] Preferably, limit blocks are installed on the inner walls of both sides of the extension frame of the cage, and limit rails are installed on both sides of the guide rail frame. The limit blocks are engaged with the surface of the limit rails, so that the cage can move vertically.

[0014] Preferably, sliders are installed on both sides of the inner cavity of the extension frame of the cage, and sliding rails are welded to the surface of the guide rail frame at the corresponding positions of the sliders. The sliders are engaged with the surface of the sliding rails, so that the cage can be raised and lowered stably.

[0015] Preferably, each mounting plate has a support rod installed at its bottom, and the bottom of each support rod is connected to the surface of the guide rail frame, which improves the stability of the mounting plate.

[0016] Preferably, mounting rods are installed on the surfaces of both the fourth and fifth gears, and the mounting rods are mounted on the surface of the mounting plate via bearings, thereby improving the stability of the fourth and fifth gears.

[0017] Beneficial effects

[0018] Compared with the prior art, this utility model provides a construction hoist that stops on time, which has the following beneficial effects:

[0019] The construction hoist that stops on time is equipped with a second motor that drives a third gear, which in turn drives a fourth gear via a first driven wheel, and then a fifth gear via a second driven wheel. The speeds of the third, fourth, and fifth gears decrease sequentially, thus driving the winding roller to rotate slowly. This control over the winding roller's speed allows for precise lifting and lowering of the hoist cage via the hoisting rope. In conjunction with the first motor, it can accurately and timely move the hoist cage to the designated floor, preventing accidents caused by personnel rushing to get on or off before reaching the target floor.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides a technical solution: a construction hoist that stops on time. Please refer to [link / reference]. Figure 1 It includes a bottom cage 1, a guide rail frame 2 is installed on the upper surface of the bottom cage 1, and a toothed rack 3 is installed on both sides of the front of the guide rail frame 2.

[0028] The cage 4 is mounted on the surface of the guide rail frame 2. Please refer to [link / reference]. Figure 3 The back of the cage 4 is equipped with a first motor 5. The rotor of the first motor 5 is coaxially equipped with a first gear 6. The surface of the first gear 6 is equipped with a second gear 7 through a connecting rod. Both the first gear 6 and the second gear 7 mesh with the surface of the rack 3.

[0029] Please see Figure 1 Mounting plate 8 is located on the upper surface of guide rail bracket 2. Please refer to [link / reference]. Figure 4 The second motor 9 is installed on the inner wall of the mounting plate 8. Please refer to [link / reference]. Figure 5The rotor output end of the second motor 9 is equipped with a third gear 10. The surface of the third gear 10 is equipped with a first driven wheel 11. The surface of the first driven wheel 11 is meshed with a fourth gear 12. The surface of the fourth gear 12 is equipped with a second driven wheel 13. The surface of the second driven wheel 13 is meshed with a fifth gear 14. The surface of the fifth gear 14 is meshed with a take-up roller 15. The surface of the take-up roller 15 is wound with a lifting rope 16. The bottom end of the lifting rope 16 is connected to the upper surface of the cage 4.

[0030] Starting the first motor 5 drives the first gear 6 and the second gear 7 to rotate synchronously, thereby moving the first gear 6 and the second gear 7 along the path of the rack 3, and thus raising and lowering the cage 4. Starting the second motor 9 drives the third gear 10 to rotate, which in turn drives the fourth gear 12 to rotate through the first driven wheel 11, and then drives the fifth gear 14 to rotate through the second driven wheel 13. At this time, the speed of the third gear 10, the fourth gear 12 and the fifth gear 14 decreases in sequence, thereby driving the winding roller 15 to rotate slowly. The speed of the winding roller 15 can be controlled, and the cage 4 can be accurately raised and lowered through the hoisting rope 16. In conjunction with the first motor 5, the cage 4 can be moved to the designated floor on time and accurately, avoiding the possibility of personnel falling due to rushing to get on or off the vehicle before reaching the target floor.

[0031] Please see Figure 2 The back of the guide rail 2 is provided with a wall mount 17. The four corners of the surface of the wall mount 17 are connected to the surface of the guide rail 2 through connecting blocks. The guide rail 2 can be installed on the wall through the wall mount 17.

[0032] Please see Figure 3 Limit blocks 18 are installed on the inner walls of both sides of the extension frame of cage 4. Please refer to [link / reference]. Figure 2 Both sides of the guide rail frame 2 are equipped with limit rails 19, and limit blocks 18 are engaged with the surface of the limit rails 19, so that the cage 4 can move vertically.

[0033] Please see Figure 3 The extension frame of the hoisting cage 4 has sliders 20 installed on both sides of its inner cavity. Please refer to [link / reference]. Figure 2 The guide rail frame 2 has a sliding rail 21 welded to the corresponding position of the slider 20. The slider 20 is engaged with the surface of the sliding rail 21, so that the cage 4 can be raised and lowered stably.

[0034] Please see Figure 4 Each mounting plate 8 has a support rod 22 installed at its bottom. The bottom of each support rod 22 is connected to the surface of the guide rail frame 2, which improves the stability of the mounting plate 8.

[0035] Please see Figure 5Mounting rods 23 are installed on the surfaces of both the fourth gear 12 and the fifth gear 14. The mounting rods 23 are mounted on the surface of the mounting plate 8 through bearings, which improves the stability of the fourth gear 12 and the fifth gear 14.

[0036] In operation, this system works as follows: First, starting the first motor 5 drives the first gear 6 and the second gear 7 to rotate synchronously, thus moving them along the path of the rack 3 and raising or lowering the cage 4. Then, starting the second motor 9 drives the third gear 10 to rotate, which in turn drives the fourth gear 12 through the first driven wheel 11, and then the fifth gear 14 through the second driven wheel 13. At this time, the speeds of the third gear 10, the fourth gear 12, and the fifth gear 14 decrease sequentially, thus driving the winding roller 15 to rotate slowly. This controls the speed of the winding roller 15, which in turn accurately raises or lowers the cage 4 via the hoisting rope 16. Finally, when the cage is about to reach the designated floor, the speed of the first motor 5 is reduced. The first motor 5 and the second motor 9 work together to slowly raise and lower the cage 4, ensuring that the cage 4 is moved to the designated floor on time and accurately, preventing accidents caused by personnel rushing to get on or off before reaching the target floor.
