Description

Technical Field

[0001] This utility model relates to the field of elevator guide rail technology, and in particular to an anti-shaking elevator guide rail connection device. Background Technology

[0002] Elevator guide rails are key guiding components in elevator systems that support the vertical movement of the car and counterweight. Made of metal profiles, they are installed on both sides of the elevator shaft wall and connected end to end by a connecting device to form a continuous track. They provide guiding support for elevator operation, ensuring the smoothness and safety of the car's lifting process, while also bearing the vertical load, horizontal impact force, and vibration load during elevator operation.

[0003] Currently, traditional elevator guide rail connection devices use simple bolt fastening or unidirectional slot structures. Although they can achieve basic connection of the guide rail and avoid the safety hazards caused by complete loosening, the existing devices connect by passing a single row of bolts through the side of the guide rail and rely on the preload of the bolts to provide friction. This can only constrain the front and back displacement of the guide rail, but lacks effective limits on left and right swaying and up and down movement. Traditional connectors are mostly flat structures with large gaps between them and the guide rail. When the elevator is running, the horizontal component force generated by the vibration of the car will cause the guide rail to shift left and right within the connector.

[0004] Traditional connecting devices rely solely on the frictional force of tightened bolts for positioning. When the elevator starts or stops or the load changes, the swaying of the guide rail in the front and back directions cannot be effectively controlled, leading to problems such as car shaking and increased noise. This not only affects passenger comfort but can also cause bolts to loosen and guide rails to deform due to long-term swaying, and may even cause safety accidents. The root cause of this structural defect is that the existing connecting devices lack multi-dimensional limiting designs for the horizontal left and right, vertical up and down, and front and back directions of the guide rails, which cannot meet the higher requirements of high-speed elevators for operational stability and safety.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0033] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5 An embodiment of this utility model provides an anti-sway elevator guide rail connection device, including an upper guide rail 1 and a lower guide rail 2. A connecting mechanism 3 is provided between the upper guide rail 1 and the lower guide rail 2. The connecting mechanism 3 is used to connect the upper guide rail 1 and the lower guide rail 2. An installation mechanism 4 is provided on the rear side of the connecting mechanism 3. The installation mechanism 4 is used to install the upper guide rail 1 and the lower guide rail 2 in the elevator shaft.

[0034] The connecting mechanism 3 includes a connector 31, which is disposed between the upper guide rail 1 and the lower guide rail 2. The connector 31 adopts a trapezoidal structure design and a symmetrical structure design. T-shaped grooves 32 are provided at both the top and bottom of the connector 31. The cross-sections of the upper guide rail 1 and the lower guide rail 2 are I-shaped. The interior of the T-shaped groove 32 is T-shaped. The rear dimensions of the upper guide rail 1 and the lower guide rail 2 match the interior dimensions of the T-shaped groove 32. The bottom end of the upper guide rail 1 is slidably connected to the interior of the top T-shaped groove 32, and the top end of the lower guide rail 2 is slidably connected to the interior of the bottom T-shaped groove 32. A guide rail stop 33 is fixedly connected inside the connector 31. Insertion components 34 are provided at both the top and bottom of the connector 31. The insertion components 34 include multiple connecting rods 341, which are respectively fixedly connected to the top and bottom of the guide rail stop 33. The upper guide rail 1... Multiple slots 342 are provided at the bottom of the upper guide rail 1 and the top of the lower guide rail 2. Multiple connecting rods 341 are slidably connected to the inside of the multiple slots 342. A positioning component 35 is provided on the front side of the connector 31. The positioning component 35 includes multiple positioning bolts 351. The multiple positioning bolts 351 pass through the top and bottom front side of the connector 31. U-shaped grooves 352 are provided on the bottom left and right sides of the upper guide rail 1 and the top left and right sides of the lower guide rail 2. Multiple positioning bolts 351 are slidably connected to the inside of the multiple U-shaped grooves 352. Fixed bolts 36 pass through the upper and lower rear ends of the connector 31. The front ends of the two fixed bolts 36 are threaded to the bottom rear end of the upper guide rail 1 and the top rear end of the lower guide rail 2. The front ends of the multiple fixed bolts 36 and the multiple positioning bolts 351 are provided with internal hexagonal grooves 37. The exterior of the multiple internal hexagonal grooves 37 is chamfered.

[0035] Specifically, the connector 31 adopts a trapezoidal symmetrical structure design and is made of QT450-10 ductile iron, which has good strength and toughness. T-shaped grooves 32 are opened at the top and bottom. The internal T-shaped structure matches the rear dimensions of the I-shaped cross-section of the upper guide rail 1 and the lower guide rail 2. The bottom end of the upper guide rail 1 slides into the top T-shaped groove 32, and the top end of the lower guide rail 2 slides into the bottom T-shaped groove 32. The limiting structure of the T-shaped groove 32 restricts the left and right swaying of the guide rail in the horizontal direction.

[0036] The guide rail stop 33 fixed inside the connector 31 is made of Q235 steel plate by cutting and welding. Its top and bottom insertion components 34 include seven evenly distributed connecting rods 341. The connecting rods 341 are made of 45# steel and have undergone quenching treatment. The slots 342 at the bottom of the upper guide rail 1 and the top of the lower guide rail 2 slide and engage with the connecting rods 341. When the guide rail is inserted into the connector 31, the connecting rods 341 insert into the slots 342, forming a vertical limit to prevent the guide rail from moving up and down. The two sides of the guide rail stop 33 are connected to the inner wall of the connector 31 by fillet welds to ensure connection strength.

[0037] In the positioning assembly 35 on the front side of the connector 31, four positioning bolts 351 penetrate through the top and bottom of the front side of the connector 31. U-shaped grooves 352 on the left and right sides of the bottom of the upper guide rail 1 and the top of the lower guide rail 2 slide in engagement with the positioning bolts 351. By rotating the positioning bolts 351, their ends press against the side of the guide rail, achieving positioning of the guide rail in the front-back direction and preventing back-and-forth swaying caused by elevator vibration. The ends of the positioning bolts 351 feature a spherical design, increasing the contact area with the side of the guide rail, reducing local pressure, and preventing damage to the guide rail surface. The fixing bolts 36 at the upper and lower ends of the rear side of the connector 31 are threaded to the bottom rear side of the upper guide rail 1 and the top rear side of the lower guide rail 2, respectively. The fixing bolts 36 are M10 high-strength bolts, with threaded holes at corresponding positions on the rear sides of the upper guide rail 1 and lower guide rail 2, using pre-tightening force to tightly connect the connector 31 to the guide rail. The internal hexagonal groove 37 of the bolt head features a chamfered design, facilitating the insertion of an internal hexagonal wrench and reducing wear during operation.

[0038] During installation, the rear sides of the I-shaped cross-sections of the upper guide rail 1 and the lower guide rail 2 are embedded in the T-shaped grooves 32 of the connector 31. The connecting rod 341 is simultaneously inserted into the slot 342. By sliding the positioning bolt 351 within the U-shaped groove 352, the center of the guide rail is aligned with the center of the connector 31. The fixing bolt 36 is then tightened using a torque wrench, generating a clamping force between the connector 31 and the guide rail. The positioning bolt 351 is tightened diagonally to ensure uniform constraint in the front-to-back direction of the guide rail. The trapezoidal symmetrical structure of the connector 31 can evenly distribute the load borne by the guide rail. When the elevator is running, the vertical load on the guide rail is decomposed into horizontal and vertical components through the inclined surface of the T-shaped groove 32. The horizontal component is borne by the two side walls of the connector 31, while the vertical component is borne jointly by the guide rail stop 33 and the fixing bolt 36. The clearance between the T-slot 32 and the guide rail effectively limits the lateral displacement of the guide rail; the clearance between the connecting rod 341 and the slot 342 can suppress the longitudinal displacement of the guide rail; the clearance between the positioning bolt 351 and the U-slot 352 can control the back-and-forth wobbling of the guide rail.

[0039] Under the elevator's rated load, the ductile iron material of connector 31 exhibits excellent shock absorption performance, absorbing vibration energy generated during elevator operation and reducing noise. The Q235 steel plate of guide rail stop 33 is galvanized to prevent rust and corrosion. The surface of connecting rod 341 is high-frequency quenched and then blackened to improve wear resistance and corrosion resistance. The surfaces of positioning bolt 351 and fixing bolt 36 are coated with Dacromet coating to ensure long-term reliability. This effectively prevents multi-directional swaying of the upper guide rail 1 and lower guide rail 2 when installing guide rails in the elevator shaft, improving the smoothness and safety of elevator operation.

[0040] Reference Figure 2 , Figure 3 and Figure 4The mounting mechanism 4 includes a rubber plate 41, which is fixedly connected to the rear side of the connector 31. The rear side of the rubber plate 41 is provided with a wavy tooth pattern 42. The tooth depth of the wavy tooth pattern 42 is set to 2-4mm and the tooth pitch is set to 3-5mm. Preferably, the tooth depth is set to 3mm and the tooth pitch is set to 4mm. The middle of the rear side of the connector 31 is provided with a mounting groove 43. A reinforcing rib 44 is fixedly connected inside the mounting groove 43. Two expansion bolts 45 pass through the left and right ends of the front side of the connector 31.

[0041] Specifically, the rubber sheet 41 is made of natural rubber with a hardness of Shore A60 and a thickness of 10mm. It is fixedly connected to the rear side of the connector 31 through a vulcanization process. The wavy serrations 42 on the rear side of the rubber sheet 41 have a tooth depth of 3mm and a tooth pitch of 4mm. They adopt an equidistant sine curve design with a curvature radius of 2mm at the crest and trough, which increases the contact area with the elevator shaft wall and provides elastic cushioning.

[0042] The mounting groove 43 is located in the middle of the rear side of the connector 31, with a depth of 8mm. The internally fixed reinforcing rib 44 is made of Q235 channel steel, with a height of 6mm and a wall thickness of 3mm. It is welded to the inner wall of the mounting groove 43 to enhance the bending resistance of the connector 31. The length of the reinforcing rib 44 is the same as that of the mounting groove 43, which can effectively distribute the load transmitted by the guide rail and reduce the stress concentration of the connector 31.

[0043] The four expansion bolts 45 that pass through the front left and right ends of the connector 31 are of M12×100 specification and are galvanized. The outer diameter of the sleeve of the expansion bolt 45 is 14mm, the expansion tube length is 50mm, and the tail is conical. When the expansion bolt 45 is screwed into the pre-drilled hole in the elevator shaft wall, the tail of the sleeve expands outward under the action of the bolt and forms a friction connection with the shaft wall. The tensile bearing capacity of a single expansion bolt 45 is 15kN and the shear bearing capacity is 8kN.

[0044] During installation, the wavy serrations 42 of the rubber sheet 41 fit tightly against the elevator shaft wall. The elastic deformation of the serrations provides a buffer space, absorbing the vibration energy generated during elevator operation. The reinforcing ribs 44 enhance the rigidity of the connector 31 through the mounting grooves 43, reducing deformation caused by stress on the guide rail. Four expansion bolts 45 are distributed diagonally to ensure uniform stress on the connector 31. Tightening the expansion bolts 45 causes the rubber sheet 41 to undergo approximately 0.5mm of compression deformation, forming a stable sealing contact surface.

[0045] During elevator operation, as the car moves up and down, the vertical load on the guide rail is transmitted to the rubber plate 41 through the connector 31. The elastic deformation of the wavy toothed groove 42 absorbs some of the vibration energy, reducing the impact on the shaft wall. Horizontal vibration is borne jointly by the reinforcing rib 44 and the expansion bolt 45. The reinforcing rib 44 distributes the load over a larger area, reducing local stress; the friction connection of the expansion bolt 45 provides sufficient shear resistance, preventing displacement of the connector 31. Testing shows that under the elevator's rated load, this installation mechanism 4 significantly improves the smoothness of elevator operation, effectively reducing vibration transmission and enhancing the stability and reliability of guide rail installation when installing guide rails within the elevator shaft.

[0046] Working principle: A detachable rigid connection is achieved through the connecting mechanism 3, and the mounting mechanism 4 on the rear side of the connecting mechanism 3 fixes the whole to the elevator shaft wall. The connecting mechanism 3 includes a trapezoidal symmetrical connecting piece 31, with T-shaped grooves 32 at the top and bottom, and a guide rail stop 33 fixed inside. Multi-directional limiting is achieved through the plug-in assembly 34, positioning assembly 35 and fixing bolts 36. The mounting mechanism 4 achieves buffering fixation and vibration absorption through rubber plate 41, reinforcing ribs 44 and expansion bolts 45. The components are precisely matched to form an anti-sway system.

[0047] The connector 31 is made of QT450-10 ductile iron, and its trapezoidal symmetrical structure allows it to bear the load evenly. The internal T-shaped structure of the top and bottom T-slots 32 matches the rear dimension of the I-shaped cross-section of the guide rail, with a fitting clearance of 0.1-0.2mm. The bottom end of the upper guide rail 1 is embedded in the top T-slot 32, and the top end of the lower guide rail 2 is embedded in the bottom T-slot 32. The vertical sidewall of the T-slot 32 restricts the left and right sway of the guide rail in the horizontal direction, and the inclined structure decomposes the vertical load into a horizontal component and a vertical component. The horizontal component is borne by the sidewall of the connector 31, ensuring that the lateral displacement of the guide rail is restricted.

[0048] The guide rail stop 33 is welded to the inside of the connector 31 from Q235 steel plate, with seven evenly distributed connecting rods 341 on both its top and bottom. The connecting rods 341 are made of 45# steel with a hardened finish of HRC40, and slide into the slots 342 at the bottom of the guide rail. When the guide rail is inserted into the connector 31, the connecting rods 341 insert into the slots 342, forming a rigid vertical limit to prevent the guide rail from moving up and down. The 0.2mm clearance suppresses longitudinal displacement. The guide rail stop 33 and the connector 31 are connected by fillet welds to ensure a stable vertical load transmission path.

[0049] Four positioning bolts 351 on the front side of connector 31 pass through the top and bottom, and slide in engagement with U-shaped grooves 352 on the guide rail. When the positioning bolts 351 are rotated, their spherical ends press against the side of the guide rail, constraining the back-and-forth movement of the guide rail through friction. The 0.5mm gap of the U-shaped grooves 352 allows for fine-tuning during installation, and the final tightening torque ensures that the positioning bolts 351 form rigid contact with the side of the guide rail, controlling back-and-forth wobble.

[0050] M10 high-strength fixing bolts 36 at the upper and lower rear ends of connector 31 penetrate connector 31, with their front ends threaded into threaded holes on the rear side of the guide rail. Pre-tightening creates a clamping force between connector 31 and the guide rail, transferring the vertical load of the guide rail to connector 31 through fixing bolts 36. Simultaneously, the bolt pre-tightening force eliminates gaps between mating surfaces, forming a rigid whole. The chamfered design of the internal hexagonal socket 37 facilitates tool operation and reduces bolt head wear.

[0051] The rubber sheet 41 is made of Shore A60 natural rubber and is fixed to the rear side of the connector 31 through a vulcanization process. The wavy toothed pattern 42 on the rear side has a tooth depth of 3mm and a tooth pitch of 4mm. Its equidistant sine curve design increases the contact area with the elevator shaft wall. When the elevator is running, the elastic deformation of the toothed pattern absorbs vibration energy, reducing the impact of the guide rail on the shaft wall.

[0052] Q235 channel steel reinforcing ribs 44 are welded into the mounting groove 43 in the middle of the rear side of the connector 31, forming a T-shaped section with the mounting groove 43. The reinforcing ribs 44 distribute the eccentric load transmitted by the guide rail to the entire connector 31, reducing local stress concentration. According to finite element analysis, its maximum stress value is reduced from 210MPa to 140MPa, which is lower than the material yield strength.

[0053] Two M12×100 expansion bolts 45 are inserted through the front left and right ends of connector 31. After being screwed into the pre-drilled holes in the well wall, the casing expands to form a friction connection with the well wall. The tensile bearing capacity of a single bolt is 15kN, and the shear bearing capacity is 8kN. The four bolts are distributed diagonally. After tightening, the rubber plate 41 undergoes a 0.5mm compression deformation, forming a sealing contact surface to prevent rainwater from seeping in while providing uniform fixing force.

[0054] When the elevator car is running, the force is decomposed into horizontal and vertical components by the inclined surface of the T-slot 32, ensuring the vertical stability of the guide rail. The 0.1-0.2mm gap of the T-slot 32 limits the lateral displacement, and the positioning bolt 351 constrains the front and rear displacement. The two work together to suppress the multi-directional swaying amplitude of the guide rail. The wavy teeth 42 of the rubber plate 41 absorbs vibration energy through elastic deformation, the reinforcing rib 44 suppresses the deformation of the connecting piece 31, and the friction connection of the expansion bolt 45 reduces system resonance. When the guide rail is installed in the elevator shaft, it effectively prevents the multi-directional swaying of the upper guide rail 1 and the lower guide rail 2, improves the smoothness and safety of elevator operation, ensures low noise and low vibration of the car operation, and meets the installation accuracy requirements of high-speed elevators.

[0055] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
