Description

Technical Field

[0001] This application relates to the technical field of elevator installation components, and in particular to a guide wheel installation structure for an elevator counterweight frame. Background Technology

[0002] An elevator is a general term for vertical transportation vehicles and fixed lifting equipment within buildings. The function of an elevator is to achieve vertical movement within a building. An elevator mainly consists of a traction machine, guiding system, counterweight, safety devices, electric drive system, hall doors and car, and signal control system. Among these, the counterweight is an essential structural component of passenger elevators, mainly composed of a counterweight frame and counterweight blocks. The counterweight blocks are fixedly installed on the counterweight frame to increase the overall weight of the counterweight frame, thereby relatively balancing the weight of the car. During elevator operation, this ensures that the weight difference between the car and the counterweight remains within limits. The essence of the counterweight is to provide balance; its function is dynamic equilibrium. Functionally, the counterweight reduces energy consumption and traction machine power loss. The counterweight is installed in the elevator shaft and connected to the car via steel cables and a traction sheave, maintaining balance between the weight of the car and the effective load portion to reduce energy consumption and motor power loss.

[0003] In existing technology, guide shoes are installed at the four corners of the counterweight frame to ensure vertical movement along the guide rails during elevator operation. A buffer is also installed at the bottom of the counterweight frame to reduce vibration during downward movement and minimize its impact on the car, thus ensuring the stability and comfort of the passenger elevator. Additionally, pairs of guide wheels are installed at the bottom of the counterweight frame. The function of these guide wheels is to guide the guide shoes and direct the counterweight frame along the guide rails. The guide wheel assembly mainly consists of a support base and guide wheels. The support base includes a base plate, columns, and positioning components. The guide wheels are mounted on the two columns. The positioning components are used to position the guide wheels. The base plate is fixed to the counterweight frame, and the columns and positioning components are fixed to the base plate. During installation, the support base and guide wheels are assembled first, and then the entire guide wheel assembly is installed at the bottom of the counterweight frame.

[0004] Regarding the aforementioned technologies, in actual use, the support base must withstand both the friction between the guide wheel and the guide rail, as well as the impact force when the guide wheel enters the bottom of the elevator shaft. Since the existing base plates are rectangular, their structural strength is poor and they are prone to deformation over a long period of time. This makes it difficult to withstand the friction between the guide wheel and the guide rail, as well as the impact force at the bottom of the elevator shaft, thus failing to meet the requirements of high-speed reciprocating operation of the elevator and threatening the stability of elevator operation. Utility Model Content

[0005] To address the problem that the base plate structure has poor strength and deforms after long-term use, making it unable to withstand the friction between the guide rollers and guide rails as well as the impact force at the bottom of the elevator shaft, thus failing to meet the requirements of high-speed reciprocating operation of the elevator and threatening the stability of elevator operation, this application provides a guide roller mounting structure for elevator counterweights.

[0006] This application provides a guide wheel mounting structure for an elevator counterweight frame, which adopts the following technical solution:

[0007] An elevator counterweight frame guide wheel mounting structure includes a support base fixed to the bottom of the counterweight frame. The support base is used to mount the guide wheel. The support base includes a base plate, a column, and a positioning component. The base plate is mounted on the bottom of the counterweight frame and is designed as an isosceles trapezoid. A mounting plate is provided in the middle of the long side of the base plate, and a snap-fit ​​groove is formed in the middle of the mounting plate. The snap-fit ​​groove matches the shape of the bottom of the counterweight frame. The positioning component is mounted on the base plate to determine the installation position of the guide wheel. The column is mounted on the base plate to mount the guide wheel.

[0008] By adopting the above technical solution, when assembling the support base, the column and positioning component are first fixed to the base plate. Then, the installation position of the guide wheel is determined by the positioning component. After that, the guide wheel is installed on the column. Then, the base plate is fixed to the bottom structure of the counterweight frame by engaging with the snap-fit ​​groove of the base plate. Finally, the base plate is fixed to the bottom of the counterweight frame. The base plate is designed as an isosceles trapezoid, which has good structural stability, can improve the strength of the overall structure, better withstand the friction between the guide wheel and the guide rail, as well as the impact load at the bottom of the elevator shaft, and reduce the occurrence of deformation. Moreover, the isosceles trapezoidal design prevents the two ends of one side of the base plate from protruding outward, thereby reducing the possibility of friction with the wire rope. The snap-fit ​​groove on the mounting plate matches the shape of the bottom of the counterweight frame, realizing the rapid positioning of the support base and the counterweight frame, simplifying the installation process, and ensuring the accuracy of the initial installation position.

[0009] Preferably, the two bottom angles formed by the long side and the two inclined sides of the base plate are cut off to prevent interference with the wire rope.

[0010] By adopting the above technical solution, the design of cutting off the bottom corner of the base plate directly avoids contact between the bottom corner of the base plate and the running wire rope, eliminates the risk of interference such as friction and collision between the two, reduces the wear of the wire rope caused by friction, extends the service life of the wire rope, reduces the elevator safety hazards caused by wire rope damage, and ensures the safety of elevator operation.

[0011] Preferably, the base plate has an oblong hole, which is set along the trapezoidal height direction of the base plate. The oblong hole cooperates with bolts to install the base plate on the counterweight frame.

[0012] By adopting the above technical solution, the oblong hole allows for minor positional adjustments to the base plate during the fixing process, facilitating precise calibration of the gap between the guide wheel and the guide rail, ensuring the fitting accuracy of the guide wheel and the guide rail, and preventing guide wheel jamming or abnormal wear caused by installation deviations; at the same time, it improves the flexibility of the installation process, reduces the requirements for the installation environment, reduces the adjustment time during installation, and improves assembly efficiency.

[0013] Preferably, the column is mounted on the base plate and perpendicular to the base plate, and a threaded through hole is provided on the column, the axis of the threaded through hole being parallel to the long side of the base plate; there are two columns, which are parallel to each other and spaced apart along the long side of the base plate; each of the two columns is provided with a threaded through hole, which is coaxially arranged, and the threaded through hole is used to install guide wheels.

[0014] By adopting the above technical solution, the parallel spacing of the two columns forms a symmetrical support structure. The rotation shaft of the guide wheel is screwed and fixed in the threaded through holes of the two columns to realize the installation of the guide wheel. The coaxial threaded through holes provide a precise positioning reference for the installation of the guide wheel, avoiding the tilting of the guide wheel caused by the misalignment of the two through holes, and enabling rapid disassembly and dismantling operations in the elevator shaft.

[0015] Preferably, one of the columns is further provided with a fixing hole, the axis of which is perpendicular to the threaded through hole and coincides with the threaded through hole.

[0016] By adopting the above technical solution, when the guide wheel is installed on the column through the threaded through hole, the bolt is screwed into the fixing hole to make the bolt abut against the guide wheel shaft, which improves the installation stability of the guide wheel.

[0017] Preferably, the end face of the column away from the base plate is provided with a threaded blind hole, the axis of the threaded blind hole is perpendicular to the axis of the threaded through hole, and the axis of the threaded blind hole is perpendicular to the base plate; both columns are provided with threaded blind holes.

[0018] By adopting the above technical solution, the guide wheel can also be rotatably installed on the column through other installation structures and threaded blind holes; the threaded blind holes allow the guide wheel to flexibly select the installation position according to the actual situation, and provide the conditions for quick disassembly and dismantling operations in the elevator shaft.

[0019] Preferably, the positioning component includes a first positioning block and a second positioning block. There are two first positioning blocks, which are spaced apart along the long side of the base plate and located on both sides of the two columns. The second positioning block is located on the side of the column with the fixing hole near the short side of the base plate. The first positioning block and the two second positioning blocks form a triangular structure on the base plate to determine the installation position of the guide wheel.

[0020] By adopting the above technical solution, the triangular layout surrounds and limits the guide wheel from three different directions, providing a precise installation benchmark for the guide wheel. This ensures that the guide wheel can quickly fall into the preset position during assembly, reducing installation errors caused by manual adjustment and improving the consistency of the guide wheel's installation position. The synergistic effect of the three positioning components enhances the positioning stability of the guide wheel. During the operation of the guide wheel, it can resist the friction and impact forces it experiences, preventing the guide wheel from shifting and ensuring the fitting accuracy between the guide wheel and the guide rail.

[0021] Preferably, both the first positioning block and the second positioning block have mounting holes that are perpendicularly through their surfaces for installing other positioning components. The axes of the mounting holes on the first positioning blocks are perpendicular to the long side of the base plate, and the axes of the mounting holes on the second positioning block are parallel to the long side of the base plate.

[0022] By adopting the above technical solution, the mounting holes are used to install relevant positioning components, ensuring that the guide wheel is accurately positioned and further preventing friction or vibration during operation due to installation deviation.

[0023] Preferably, the first positioning block has a protrusion on the side closest to the long side of the base plate, and the mounting hole is perpendicular to the side of the first positioning block with the protrusion; the protrusion and the first positioning block together form an L-shaped structure, and the protrusion is oriented towards the long side of the base plate.

[0024] By adopting the above technical solution, the L-shaped structure provides a clear limiting reference for the installation of the guide wheel through the right angle formed by the protrusion and the positioning component. During the assembly of the guide wheel, it can be quickly aligned with the right angle side of the L-shaped structure, reducing the adjustment time during the installation process and improving the assembly efficiency.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. When assembling the support base, first fix the column and positioning components to the base plate, then determine the installation position of the guide wheel using the positioning components, then install the guide wheel on the column, and then determine the installation position of the base plate by engaging with the bottom structure of the counterweight frame through the snap-fit ​​groove of the base plate. Finally, fix the base plate to the bottom of the counterweight frame. The base plate is designed as an isosceles trapezoid, which has good structural stability, can improve the strength of the overall structure, better withstand the friction between the guide wheel and the guide rail, as well as the impact load entering the bottom of the elevator shaft, and reduce the occurrence of deformation. In addition, the isosceles trapezoidal design prevents the two ends of one side of the base plate from protruding outward, thereby reducing the possibility of friction with the wire rope. The snap-fit ​​groove on the mounting plate matches the shape of the bottom of the counterweight frame, realizing the quick positioning of the support base and the counterweight frame, simplifying the installation process, and ensuring the accuracy of the initial installation position.

[0027] 2. The design of cutting off the bottom corner of the base plate directly and further avoids contact between the bottom corner of the base plate and the running wire rope, eliminating the risk of interference such as friction and collision between the two, reducing the wear of the wire rope caused by friction, extending the service life of the wire rope, reducing the elevator safety hazards caused by wire rope damage, and ensuring the safety of elevator operation.

[0028] 3. The oblong holes on the base plate allow for minute position adjustments during fixing, facilitating precise calibration of the gap between the guide wheels and guide rails. This ensures the fit between the guide wheels and guide rails, preventing guide wheel jamming or abnormal wear due to installation deviations. It also enhances installation flexibility, reduces environmental requirements, shortens adjustment time, and improves assembly efficiency. The threaded blind holes and threaded through holes on the two columns enable quick installation and removal of the guide wheels, while also improving installation stability.

[0035] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail.

[0036] This application discloses a guide wheel mounting structure for an elevator counterweight frame.

[0037] refer to Figure 1An elevator counterweight frame guide wheel mounting structure includes a support seat 1 for mounting guide wheels, the support seat 1 being installed at the bottom of the counterweight frame; the support seat 1 includes a base plate 11, a column 12 for mounting guide wheels, and a positioning element 13 for determining the mounting position of the guide wheels, the base plate 11 being installed at the bottom of the counterweight frame, and the column 12 and the positioning element 13 being installed on the base plate 11.

[0038] refer to Figure 1 and Figure 2 The base plate 11 is an isosceles trapezoidal plate. The design of the base plate 11 as an isosceles trapezoid has good structural stability, which can improve the strength of the overall structure, better withstand the friction between the guide wheel and the guide rail and the impact load when entering the bottom of the elevator shaft, and reduce the occurrence of deformation. In addition, the isosceles trapezoidal design prevents the two ends of one side of the base plate 11 from bulging outward, thereby reducing the possibility of friction with the wire rope.

[0039] The two bottom corners formed by the long side and the two inclined sides of the base plate 11 are cut off, forming right angles at both ends of the long side of the base plate 11. This prevents the two bottom corners formed by the long side and the two inclined sides of the base plate 11 from protruding and interfering with the wire rope. It avoids contact between the corners of the base plate 11 and the running wire rope, eliminates the risk of interference such as friction and collision between the two, reduces the wear of the wire rope caused by friction, extends the service life of the wire rope, reduces the elevator safety hazards caused by wire rope damage, and ensures the safety of elevator operation.

[0040] A mounting plate 2 is integrally formed on the middle of the long side of the base plate 11. The mounting plate 2 is trapezoidal in shape and has a snap-fit ​​groove 3 that matches the shape of the bottom of the counterweight frame. The snap-fit ​​groove 3 is located in the middle of the side of the mounting plate 2 away from the base plate 11. In this embodiment, the snap-fit ​​groove 3 is a rectangular groove, and the depth of the snap-fit ​​groove 3 is the same as the height of the trapezoid of the mounting plate 2. The snap-fit ​​groove 3 on the mounting plate 2 matches the shape of the bottom of the counterweight frame, realizing the rapid positioning of the support 1 and the counterweight frame, simplifying the installation process, and ensuring the accuracy of the initial installation position.

[0041] When assembling the support base 1, first fix the column 12 and the positioning part 13 on the base plate 11, then determine the installation position of the guide wheel through the positioning part 13, then install the guide wheel on the column 12, then determine the installation position of the base plate 11 by engaging with the bottom structure of the counterweight frame through the snap-fit ​​groove 3 of the base plate 11, and finally fix the base plate 11 to the bottom of the counterweight frame.

[0042] The base plate 11 has oblong holes 4 along its trapezoidal height direction. Bolts are used to fix the base plate 11 to the counterweight frame through these oblong holes 4. In this embodiment, two oblong holes 4 are provided. The oblong holes allow for minor positional adjustments to the base plate 11 during fixing, facilitating precise calibration of the gap between the guide wheels and guide rails, ensuring the fitting accuracy of the guide wheels and guide rails, and preventing guide wheel jamming or abnormal wear due to installation deviations. Simultaneously, it improves the flexibility of the installation process, reduces the requirements for the installation environment, reduces adjustment time during installation, and improves assembly efficiency.

[0043] refer to Figure 1 and Figure 3 The column 12 is a rectangular column, welded and fixed to the base plate 11, and is perpendicular to the base plate 11. A threaded through hole 5 is formed in the column 12, with the axis of the threaded through hole 5 parallel to the long side of the base plate 11. Two columns 12 are provided, parallel to each other and spaced apart along the long side of the base plate 11. Each column 12 has a threaded through hole 5, which are coaxial. The parallel spacing of the two columns 12 forms a symmetrical support structure. The rotation shaft of the guide wheel is inserted into the threaded through holes 5 of the two columns 12 to install the guide wheel. The coaxial threaded through holes 5 provide a precise positioning reference for the installation of the guide wheel, avoiding tilting of the guide wheel due to misalignment of the two through holes, and also enabling rapid disassembly and dismantling operations within the elevator shaft.

[0044] One of the columns 12 has a fixing hole 6, the axis of the fixing hole 6 is perpendicular to the threaded through hole 5 and coincides with the threaded through hole 5; when the guide wheel is installed on the column 12 through the threaded through hole 5, the bolt is screwed into the fixing hole 6 to make the bolt abut against the guide wheel shaft, which improves the installation stability of the guide wheel; in other embodiments, both columns 12 have fixing holes 6.

[0045] A threaded blind hole 7 is provided on the end face of the column 12 away from the base plate 11. The axis of the threaded blind hole 7 is set perpendicular to the base plate 11 and perpendicular to the axis of the threaded through hole 5. Threaded blind holes 7 are provided on both columns 12. The guide wheel can also be rotatably installed on the column 12 through other installation structures in cooperation with the threaded blind hole 7. The threaded blind hole 7 allows the guide wheel to flexibly select the installation position according to the actual situation and has the conditions for quick disassembly and dismantling operations in the elevator shaft.

[0046] refer to Figure 1 , Figure 4 and Figure 5The positioning component 13 includes a first positioning block 131 and a second positioning block 132, both of which are rectangular blocks. There are two first positioning blocks 131, which are spaced apart along the long side of the base plate 11 and located on both sides of the two columns 12. The second positioning block 132 is located on the side of the column 12 with the fixing hole 6 near the short side of the base plate 11. The first positioning block 131 and the two second positioning blocks 132 form a triangular structure on the base plate 11 to determine the installation position of the guide wheel.

[0047] The triangular structure surrounds and limits the guide wheel from three different directions, providing a precise installation benchmark for the guide wheel. This ensures that the guide wheel can quickly fall into the preset position during assembly, reducing installation errors caused by manual adjustment and improving the consistency of the guide wheel's installation position. The synergistic effect of the three positioning components 13 enhances the positioning stability of the guide wheel. During the operation of the guide wheel, it can resist the friction and impact forces it is subjected to, preventing the guide wheel from shifting and ensuring the fitting accuracy between the guide wheel and the guide rail.

[0048] The first positioning block 131 is welded and fixed to the base plate 11. The surface of the first positioning block 131 is provided with a vertical through-hole 8 for installing other positioning components. The axis of the mounting hole 8 is perpendicular to the long side of the base plate 11. There are two first positioning blocks 131, and the axes of the mounting holes 8 on both first positioning blocks 131 are parallel to the long side of the base plate 11. The surface of the second positioning block 132 is also provided with a vertical through-hole 8. The axis of the mounting hole 8 on the second positioning block 132 is parallel to the long side of the base plate 11. The mounting holes 8 are used to install relevant positioning components to ensure the accurate positioning of the guide wheel and further prevent friction or vibration during operation due to installation deviation.

[0049] The first positioning block 131 has a protrusion 9 integrally provided on one side near the long side of the base plate 11. The mounting hole 8 is perpendicular to the side of the first positioning block 131 where the protrusion 9 is provided. The protrusion 9 and the first positioning block 131 form an L-shaped structure, with the protrusion 9 facing the long side of the base plate 11. The L-shaped structure provides a clear limiting reference for the installation of the guide wheel through the right angle formed by the protrusion 9 and the positioning member 13. When assembling the guide wheel, it can be quickly aligned with the right angle side of the L-shaped structure, reducing the adjustment time during the installation process and improving the assembly efficiency.

[0050] The implementation principle of this application embodiment is as follows: First, two columns 12 are vertically welded and fixed to the base plate 11, with one end of each column 12 having a threaded blind hole 7 away from the base plate 11; the protrusions 9 of the two first positioning blocks 131 are oriented towards the long side of the trapezoid, and the first positioning blocks 131 are placed on both sides of the two columns 12, and the two first positioning blocks 131 are welded and fixed to the base plate 11; the second positioning block 132 is placed on the side of one of the columns 12 closest to the short side of the base plate 11, and the axis of the mounting hole 8 of the second positioning block 132 is parallel to the long side of the base plate 11. 132 is welded and fixed to the base plate 11, completing the assembly of the support seat 1; when the support seat 1 is installed at the bottom of the counterweight frame, the snap-fit ​​groove 3 on the mounting plate 2 matches the shape of the bottom of the counterweight frame, thereby determining the installation position of the base plate 11; the support seat 1 is fixed to the bottom of the counterweight frame by screwing the bolts through the waist-shaped holes 4 on the base plate 11; then the two ends of the guide wheel shaft are screwed and fixed in the threaded through holes 5 of the two columns 12 respectively, fixing the guide wheel; the guide wheel can also be rotatably installed on the column 12 by other installation structures and threaded blind holes 7.

[0051] The base plate 11 is designed as an isosceles trapezoid, which has good structural stability, can improve the strength of the overall structure, better withstand the friction between the guide wheel and the guide rail and the impact load when entering the bottom of the elevator shaft, and reduce the occurrence of deformation. In addition, the isosceles trapezoidal design prevents the two ends of one side of the base plate 11 from protruding outward, thereby reducing the possibility of friction with the wire rope. The snap-fit ​​groove 3 on the mounting plate 2 matches the shape of the bottom of the counterweight frame, realizing the quick positioning of the support seat 1 and the counterweight frame, simplifying the installation process and ensuring the accuracy of the initial installation position.
