Description

Technical Field

[0001] This utility model relates to the field of elevator shaft technology, specifically to a vertical transportation device that can be quickly installed and disassembled using an elevator shaft. Background Technology

[0002] Traditionally, the installation of elevator car frames within elevator shafts typically involves using numerous bolts and nuts to secure various components. Taking a common frame-type car frame as an example, the connection between the columns and beams, and the fixing of the car walls to the main body of the car frame, often require workers to use specialized tools to tighten a large number of bolts one by one. In some large elevator projects, the assembly of the car frame alone may involve the installation of hundreds or even thousands of bolts. This installation method not only consumes a significant amount of manpower and time but also places high demands on the physical strength and technical proficiency of the workers. Moreover, performing bolt tightening work for extended periods within the narrow confines of the elevator shaft presents a harsh working environment and significant safety risks.

[0003] Once an elevator is put into use, it inevitably faces situations requiring maintenance of the car frame, replacement of components, or upgrades to the elevator system. At these times, the dismantling of the traditional car frame presents significant challenges. Because the components are tightly connected by numerous bolts, dismantling requires workers to unscrew each bolt sequentially, taking extreme care to prevent components from falling due to sudden loosening. If the bolts are rusted, corroded, or have damaged threads due to long-term use, the difficulty of dismantling increases exponentially, potentially requiring the use of special tools or even destructive dismantling methods. This not only further prolongs maintenance time but may also cause unnecessary damage to the car frame and surrounding equipment, increasing maintenance costs.

[0004] Furthermore, the traditional bolted connection method for elevator car frames has the problem of difficulty in ensuring connection accuracy. Because the installation process relies on manual tightening of each bolt, it is difficult to achieve uniform preload between components. This not only affects the overall stability and load-bearing capacity of the car frame, but may also cause abnormal vibration and noise during elevator operation, reducing passenger comfort and elevator lifespan.

[0005] While some elevator components on the market currently employ quick-connect structures, these are mostly for non-load-bearing parts. For the car frame, which is the core load-bearing structure, there is no mature quick-disassembly and assembly technology solution, making it difficult to meet the demands of modern building construction for efficiency and safety. Utility Model Content

[0006] In view of the problems of time-consuming and labor-intensive installation and disassembly of elevator car frames in existing technologies, high safety risks, and poor connection accuracy, this utility model provides a vertical transportation device that can be quickly installed and disassembled using the elevator shaft. Through modular design and gear locking structure, it realizes the rapid assembly and disassembly of the car frame, improves construction efficiency and ensures operation safety.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A vertical transportation device utilizing an elevator shaft that can be quickly installed and disassembled includes a car module frame body.

[0009] Preferably, the number of the plug-in bottom feet is set to four, and the number of the plug-in top feet is set to four that cooperate with the plug-in bottom feet. Each plug-in bottom foot has a meshing gear rotatably installed on both sides.

[0010] Preferably, the top pin of the connector is provided with a slot, the diameter of the slot is the same as the diameter of the bottom pin of the connector, and the bottom pin of the connector is engaged with the top pin of the connector through the slot.

[0011] Preferably, both the plug-in base and the slot are provided with plug-in bevels, and the plug-in base and the slot are tightly plugged into each other through the plug-in bevels.

[0012] Preferably, gear boxes are provided on both sides of the plug-in pin, and the one-way gear slides between the slot and the gear box.

[0013] Preferably, the one-way gear is provided with a ratchet assembly, and one end of the one-way gear is provided with a movable adjusting rod. The one-way gear is rotatably mounted on the movable adjusting rod through the ratchet assembly.

[0014] Preferably, a tension spring is provided on the movable adjusting rod. The tension spring is located inside the gear box and is inclined. One end of the tension spring is connected to the movable adjusting rod, and the other end is connected to the inner wall of the gear box.

[0015] Preferably, the gear box has pin positioning holes on its outer sidewall and the movable adjusting rod. A U-shaped pin rod can be slidably installed in the pin positioning hole, and the U-shaped pin rod and the pin hole are tightly fitted together.

[0016] Compared with existing technologies, the beneficial effects of this utility model are as follows:

[0017] 1. The vertical transportation device utilizing elevator shafts that can be quickly installed and disassembled as described in this utility model is equipped with a quick-locking structure consisting of a plug-in top foot, a plug-in bottom foot, a one-way gear, and a meshing gear.

No bolt tools are required, and a single person can complete the installation of a single connection point within 2 minutes. Compared with traditional bolt connections, the efficiency is improved by more than 80%, effectively solving the problem of time-consuming and labor-intensive installation of traditional car frames.

[0018] 2.

Furthermore, during disassembly, simply pulling out the U-shaped pin and pressing the movable adjusting rod releases the lock. The disassembly process is safe and convenient, solving the problem of high safety risks associated with traditional disassembly methods.

[0019] 3. The vertical transportation device utilizing elevator shafts that can be quickly installed and disassembled as described in this utility model adopts a standardized modular design. The processing accuracy of each component is controlled within 0.5mm. Automatic centering is achieved through the insertion of inclined surfaces and gear locking structure. The connection preload is uniform and consistent. Actual measurements show that the vibration amplitude is ≤0.1mm and the noise level is ≤55dB during operation. This solves the vibration and noise problem caused by the poor accuracy of traditional bolt connections and improves the stability and service life of the device. Attached Figure Description

[0024] 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.

[0025] like Figures 1 to 3 As shown, this utility model provides a vertical transportation device utilizing an elevator shaft that can be quickly installed and disassembled. It includes a car module frame 1, which is a square frame structure welded from high-strength aluminum alloy or steel to ensure structural strength and lightweight. The top of the car module frame 1 is provided with a top insertion foot 2, and the bottom of the car module frame 1 is provided with a bottom insertion foot 3. A one-way gear 4 is installed inside the top insertion foot 2, and meshing gears 5 are provided on both sides of the bottom insertion foot 3. When the bottom insertion foot 3 and the top insertion foot 2 are inserted and engaged, the one-way gear 4 will rotate and lock in one direction with the meshing gears 5.

[0026] Furthermore, the number of plug-in bottom feet 3 is set to four, symmetrically distributed at the four corners of the bottom of the car module frame 1. The number of plug-in top feet 2 is set to four, which cooperate with the plug-in bottom feet 3, and installed at the four corners of the top of the car module frame 1. Each plug-in bottom foot 3 has a meshing gear 5 installed on both sides through bearings to ensure smooth gear rotation.

[0027] The top pin 2 has a slot 6, the diameter of which is the same as that of the bottom pin 3. The bottom pin 3 and the top pin 2 are interlocked through the slot 6, and a guide structure ensures accurate alignment during the insertion process. To further improve the insertion efficiency and tightness, both the bottom pin 3 and the slot 6 are provided with an insertion bevel 7. The bottom pin 3 and the slot 6 are tightly interlocked through the insertion bevel 7. The inclination angle of the insertion bevel 7 is 15°-30°, which facilitates quick insertion and guides alignment.

[0028] Gear boxes 8 are fixedly installed on both sides of the plug-in pin 2. The one-way gear 4 slides between the slot 6 and the gear box 8. The gear box 8 adopts a sealed design to prevent dust and debris in the well from entering and affecting the operation of the gear.

[0029] A ratchet assembly 9 is provided on the one-way gear 4, and a movable adjusting rod 10 is provided at one end of the one-way gear 4. The one-way gear 4 is rotatably mounted on the movable adjusting rod 10 through the ratchet assembly 9. The ratchet assembly 9 adopts a standard ratchet structure to realize the one-way locking function.

[0030] A tension spring 11 is fitted on the movable adjustment rod 10. The tension spring 11 is located inside the gear box 8 and is inclined. One end of the tension spring 11 is connected to the movable adjustment rod 10, and the other end is connected to the inner wall of the gear box 8. The elastic coefficient of the tension spring 11 is designed to match the load-bearing weight of the car frame to ensure reliable locking force.

[0031] The gear box 8 has pin positioning holes on its outer sidewall and the movable adjusting rod 10. A U-shaped pin rod 13 can be slidably installed on the pin positioning hole. The U-shaped pin rod 13 and the pin hole 12 fit tightly together. The diameter of the pin hole 12 and the rod diameter of the U-shaped pin rod 13 are controlled within 0.1mm to ensure positioning accuracy.

[0032] Working Principle: During installation, firstly, align the top pin 2 of the lower car module frame 1 with the bottom pin 3 of the upper car module frame 1. Using the guiding action of the inclined surface 7, insert the bottom pin 3 into the slot 6. During insertion, the meshing gears 5 on both sides of the bottom pin 3 contact the one-way gear 4 inside the top pin 2. As the insertion depth increases, the meshing gears 5 push the one-way gear 4 to rotate around the movable adjusting rod 10. At this time, the tension spring 11 is in a stretched state, providing a reset force for the movable adjusting rod 10. When the bottom pin 3 is fully inserted into the slot 6, the one-way gear 4 and the meshing gear 5 are fully engaged, and the ratchet assembly 9 automatically locks the rotation of the one-way gear 4, thus completing the quick locking connection of the two car module frames 1. Finally, press the movable adjusting rod 10 so that the pin hole 12 on the gear box 8 and the pin hole 12 on the movable adjusting rod 10 engage, inserting the U-shaped pin 13 into the pin positioning hole of the gear box 8 and the movable adjusting rod 10 to position the movable adjusting rod 10 and ensure the reliability of the locking structure. The U-shaped pin 13, as a safety redundancy structure, further locks the position of the movable adjusting rod 10, preventing locking failure due to vibration or other factors during transportation.

[0033] During disassembly, first pull out the U-shaped pin 13, then pull the movable adjusting rod 10 to compress the tension spring 11, causing the one-way gear 4 to disengage from the meshing gear 5 and releasing the lock. At this point, lift the upper car module frame 1 upwards, and using the smooth structure of the insertion ramp 7, the insertion foot 3 can be pulled out of the slot 6, completing the quick disassembly operation.

[0034] In summary, the vertical transportation device utilizing elevator shafts that can be quickly installed and disassembled, provided by this utility model, achieves rapid installation and disassembly of the car frame through innovative mechanical structure design, significantly improving construction efficiency, reducing operational safety risks, and ensuring connection accuracy and device stability. It has broad engineering application value and market promotion prospects.
