Description

Technical Field

[0001] This disclosure relates to the field of elevator technology, and more particularly to apparatus and methods for installing and adjusting roller guide shoes, as well as elevator systems. Background Technology

[0002] Elevators are widely installed and used in high-rise buildings, transportation hubs (such as train stations and airport terminals), family villas, and private clubs as basic equipment to ensure people's daily travel. These elevators generally use rolling guide shoe technology. When the elevator car moves up and down along the guide rail, the rolling guide shoe forms rolling friction between the roller and the guide rail. Compared with the traditional sliding friction method, this can reduce running resistance and improve equipment stability.

[0003] Rolling guide shoes are typically installed in pairs on the elevator car frame columns, usually one at the top and one at the bottom of each frame column. During assembly, the rolling guide shoes undergo a positioning calibration to ensure accurate placement and final fixation to their designed installation positions. In some elevator systems, when the elevator car is stationary, the rollers in the rolling guide shoes maintain contact pressure with the elevator guide rail surface. Summary of the Invention

[0004] In view of this, the present disclosure provides an apparatus and method for installing and adjusting roller guide shoes, as well as an elevator system, to solve or at least alleviate one or more of the above-mentioned and other problems existing in the prior art, or to provide an alternative to the prior art.

[0021] In the device for installing and adjusting roller guide shoes according to the present disclosure, optionally, the first gap is in the range of 1-10 mm, and the second gap is not less than 1 mm.

[0022] In the apparatus for mounting and adjusting roller guide shoes according to the present disclosure, optionally, the mating member is provided with different sections, the contact member generates different magnitudes of force when in contact with the different sections, and / or the contact member includes a rolling element.

[0023] In the device for installing and adjusting roller guide shoes according to the present disclosure, optionally, the mating member has a first section and a second section, the first section being connected to the second section and arranged along the length direction of the elevator guide rail, the first section having a cross-section that gradually increases toward the second section, the surface of the second section being parallel to the surface of the elevator guide rail, and the contact member abutting against the surface of the second section when the elevator car stops near the preset position.

[0024] In the device for installing and adjusting roller guide shoes according to the present disclosure, optionally, the preset position is set at a first distance from the top of the elevator shaft or a second distance from the bottom of the elevator shaft, wherein both the first distance and the second distance are not less than 1m.

[0025] In the device for installing and adjusting roller guide shoes according to this disclosure, optionally, the elevator car stops near the preset position when the elevator system is in a preset state, the preset state including an idle state and a stopped state.

[0026] Furthermore, according to another aspect of this disclosure, an elevator system is also provided, comprising:

[0027] One or more elevator cars configured to operate within an elevator shaft; and

[0028] The device for installing and adjusting the roller guide shoe as described in any of the above is installed on the car frame column of the elevator car.

[0038] This disclosed solution innovatively provides a combined function for the installation, positioning, and pressure adjustment of roller guide shoes. It not only allows for accurate, efficient, and convenient installation of the roller guide shoes onto the elevator car, achieving a larger contact area between the roller guide shoes and the elevator guide rails, but also provides effective protection for the roller guide shoes. This avoids or mitigates deformation or damage to the rollers within the roller guide shoes due to pressure exerted on the elevator guide rails, particularly static pressure. Consequently, it reduces the impact of vibration, shock, and noise, extends the service life of components, improves elevator operational smoothness, and enhances passenger comfort. This disclosed solution is highly practical and applicable to numerous types of elevator systems, including home elevators and public elevators, covering a wide range of application scenarios.

[0047] Figure 9 This is a schematic diagram of the processing steps according to an embodiment of the method for installing and adjusting pressure of roller guide shoes according to the present disclosure. Detailed Implementation

[0048] Figure 1 This is a perspective view of an elevator system 100, which may include an elevator car 103, a counterweight 105, a tensioning component 107, guide rails (or guide rail system) 109, a machine unit (or machine unit system) 111, a position reference device 113, and an electronic elevator controller (controller) 115. The elevator car 103 and the counterweight 105 are connected to each other via the tensioning component 107 and move along the elevator shaft 117 under driving force. The tensioning component 107 may include, for example, steel belts (such as coated steel belts) and / or ropes (such as wire ropes). The counterweight 105 may be configured to balance the load of the elevator car 103 and may be configured to facilitate simultaneous and opposite-direction movement of the elevator car 103 relative to the counterweight 105 along the guide rails 109 within the elevator shaft 117.

[0049] Tensioning member 107 can engage unit 111, which can be configured to control movement between elevator car 103 and counterweight 105. Unit 111 may include a motor or similar power unit to provide driving force to elevator system 100, and may be in a machine room-less configuration. Position reference device 113 may be arranged in other locations and / or configurations known in the art, such as mounted on a fixed portion at the top of elevator shaft 117. Position reference device 113 may be configured to provide a position signal relating to the position of elevator car and / or counterweight within the elevator shaft, and may employ any device or mechanism known in the art for monitoring the position of elevator car and / or counterweight, such as, but not limited to, encoders, sensors, or other components, and may include speed sensing, absolute position sensing, etc.

[0050] Controller 115 may be located in controller room 121 of elevator shaft 117 and may be configured to control the operation of elevator system 100 (particularly elevator car 103). For example, controller 115 may provide drive signals to unit 111 to control the acceleration, deceleration, leveling, stopping, etc. of elevator car 103. Controller 115 may also be configured to receive position signals from position reference device 113 or any other desired such device or system. When moving up or down along guide rail 109 within elevator shaft 117, elevator car 103 may stop at one or more elevator floors 125 as controlled by controller 115. Although controller 115 is shown in controller room 121, those skilled in the art will appreciate that controller 115 may be located and / or configured in other places or locations within elevator system 100, such as remotely located or in the cloud.

[0051] The above shows and describes specific elevator systems and components. Unless otherwise specified herein, other elevator systems and components may be used as examples. Figure 1 The components in the elevator system examples are applied to other elevator system embodiments according to this disclosure to achieve the same or similar functions. This disclosure provides a multi-functional device for elevator systems, applicable to roller guide shoe installation, pressure regulation, etc., and is particularly suitable for environments with relatively small elevator shaft spaces, such as home elevators. The following will combine... Figures 2 to 8 The specific embodiments shown provide a detailed description of this device. For the sake of simplicity in the drawings, the same or similar parts and features may be indicated only in one or more places in the same drawing. Technical terms such as "first," "second," and "third" are used for distinguishing purposes only and are not intended to indicate their order or relative importance. The technical term "connection" includes connections implemented in a direct or indirect manner.

[0052] First refer to Figure 2 and Figure 3 These two accompanying figures schematically illustrate two car frame column structures in an example of an elevator car and their approximate contact and guidance with their respective corresponding elevator guide rail examples. Roller guide shoes and an embodiment of a device for installing and adjusting the roller guide shoes according to this disclosure are mounted on these car frame columns. Although the mating parts in this device embodiment are not shown in the figures, they are... Figures 6 to 8 The image shows a general illustration of the installation and use of the aforementioned mating components.

[0053] As an example, as used in the embodiments herein, the elevator car 103 may have a side-mounted car frame column 104, and a roller guide shoe 110 may be installed at the upper and lower positions of each car frame column 104. These two roller guide shoes 110 can be configured as follows: Figure 2The arrangement of the roller guide shoes is relatively inverted, forming a so-called "backpack" structure. This type of elevator has advantages such as relatively simple configuration, space saving, convenient installation, and low cost, and is therefore commonly used in many applications such as home elevators and private club elevators. Each roller guide shoe 110 can be equipped with a corresponding device 130 for roller guide shoe installation and pressure adjustment. For example, the device 130 (except for the mating part 136) can be arranged adjacent to the roller guide shoe 110. Figure 2 and Figure 3 A demonstrative demonstration was conducted in China.

[0054] In the given embodiment, device 130 may include a bracket 131, a positioning portion, and a pressure adjusting portion. Specifically, bracket 131 may be made of a rigid material such as steel or iron and may be manufactured in any suitable shape as needed. A detachable mechanism may be used as needed (e.g., Figure 8 The bracket 131 is installed onto the car frame column 104 of the elevator car 103 by any feasible means such as connecting parts 150 (e.g., bolts, welding) to provide support for components in, for example, the positioning part and the pressure regulating part.

[0055] The positioning part in device 130 can be detachably installed on bracket 131. Before the roller guide shoe 110 is installed on the car frame column 104, the positioning part can be operated to limit the installation reference for assembling the roller guide shoe 110 on the car frame column 104, for example, to make the car frame column 104 meet the corresponding requirements of the specific application in terms of verticality, horizontality, etc.

[0056] Specifically, the positioning part can be operated to be in different states. For example, in the first state (or positioning state), the car frame column 104 can be fixed in the expected position relative to the elevator guide rail 109 through the positioning part. The elevator guide rail 109 has been fixed in place on site by means of, for example, guide rail brackets to meet the preset requirements. Thus, the relative position of the car frame column 104 and the elevator guide rail 109 can be fixed through the positioning part, so that the above positioning can be used as the installation reference for the roller guide shoe 110. In this way, the roller guide shoe 110 can be installed on the car frame column 104 very conveniently and accurately. For another example, the positioning part can be operated to release the positioning of the car frame column 104 relative to the elevator guide rail 109, that is, switch from the first state to the second state (or release positioning state). The latter is usually the normal state of the positioning part, that is, when the elevator system is running normally, the positioning part is in the second state.

[0057] It should be understood that the switching operation of the positioning part between different states can be achieved by selecting and setting a suitable relative movement mode between the positioning part and the car frame column as needed, such as linear movement relative to the car frame column or rotation relative to the car frame column to change their relative positions. This disclosure does not impose any limitations in this regard. In addition, those skilled in the art will understand and know that in the process of fixing the elevator guide rail 109 in place on site and adjusting and positioning the car frame column 104 relative to the elevator guide rail 109, tools and equipment such as laser levels, electronic levels, and guide rulers are usually used to ensure that the verticality and horizontality meet the standards. Therefore, this disclosure will not discuss them in detail.

[0058] For better understanding, as an illustrative example, see, for example, reference... Figure 4 , Figure 5 and Figure 8 As shown, the positioning section can be configured to include a first component 132, a second component 133, and a third component 134. Specifically, the first component 132 and the second component 133 can be configured to... Figure 2 and Figure 3 The first component 132 can be moved relative to the bracket 131 in the first direction X (i.e., the width direction of the vertical car frame column 104 after installation), thereby allowing the first component 132 to abut or dismount from the first side surface 109a of the elevator guide rail 109, and the second component 133 to abut or dismount from the second side surface 109b of the elevator guide rail 109 (which is opposite to the first side surface 109a) through corresponding operations; furthermore, the third component 134 can be configured to... Figure 2 and Figure 3 The third component 134 moves relative to the bracket 131 in the second direction Y (which is perpendicular to the first direction X and the vertical direction Z of the elevator shaft) so that it can be operated accordingly to make the third component 134 abut or disengage from the outer end face 109c of the elevator guide rail 109.

[0059] As described above, by operating these components 132, 133, and 134, they can be made to abut or disengage from the first side surface 109a, the second side surface 109b, and the outer end face 109c, respectively. This allows for precise positioning and locking of the car frame column 104 relative to the installed elevator guide rail 109 through repeated operations. This enables accurate adjustment and fixing of the relative position of the car frame column 104 and the elevator guide rail 109 in three-dimensional space, placing the positioning part in the first state. This provides an accurate installation reference for the installation of the roller guide shoe 110 onto the car frame column 104. The roller guide shoe 110 can then be directly assembled onto the now-positioned car frame column 104. By performing the reverse operation, the positioning part can be placed in the second state.

[0060] As an example, the first component 132, the second component 133, and the third component 134 can all be configured as adjustable bolts. Such bolt components are not only readily available but also easy to operate and maintain, and are inexpensive. In one or more embodiments, any one or more of the first component 132, the second component 133, and the third component 134 can be constructed with a relatively complex structure, for example, a linkage mechanism can be configured to achieve linkage operation between two or three of them, so as to make operation easier, more efficient, and more accurate.

[0061] For the installation of roller guide shoes, the prior art does not consider or provide a device according to this disclosure. Figure 4 Taking the roller guide shoe shown in the diagram as an example for comparison, in existing technologies, when installing roller guide shoes, the common practice is to first insert the roller guide shoe shaft 110b (usually an eccentric shaft used to adjust the position of the roller guide shoe and the safety clearance between it and the elevator guide rail) into the corresponding mounting hole on the car frame column, and then adjust the position of the roller guide shoe. During adjustment, this can only be done within... Figure 2 The adjustment is performed in the first direction X, and the adjustment amount is generally only 0-2mm. Furthermore, during the adjustment of the car frame column verticality, the rollers 110a and 111c located on both sides of the elevator guide rail in the roller guide shoes are often in a compressed state, making adjustment and installation difficult. Additionally, because the roller guide shoes are always under load during adjustment, it is difficult to improve the contact surface between the roller guide shoes and the elevator guide rail to an ideal state during installation. Consequently, if the contact surface between the roller guide shoes and the elevator guide rail is small after installation, it will affect the operating quality of the elevator car and the service life of the roller guide shoes.

[0062] The present invention successfully solves the above problems. As mentioned above, by using the device of this invention, the relative position between the car frame column 104 and the elevator guide rail 109, which has been installed on site, is first fixed according to the application requirements using the positioning part. This provides an accurate installation reference for the subsequent assembly operation of the roller guide shoe 110 onto the car frame column 104. Then, the roller guide shoe 110 can be directly installed and fixed into its installation position. Not only is the entire installation process very simple, but it can also effectively eliminate or reduce assembly errors, better adjust and achieve a safe clearance between the roller guide shoe and the elevator guide rail, and obtain a larger contact surface between the roller guide shoe and the elevator guide rail. This is very beneficial for improving the smoothness of elevator operation, reducing the load on the roller guide shoe, and extending its service life. In addition, using the present invention, ordinary roller guide shoes with non-eccentric shafts can be installed on the elevator car, which is also more conducive to adjusting and achieving a relatively larger contact surface between the roller guide shoe and the elevator guide rail, optimizing the load condition of the roller guide shoe.

[0063] Continue to refer to Figure 4 and Figure 5 As an optional configuration, the bracket 131 can be constructed with a first protrusion 131a and a second protrusion 131b for mounting and supporting the first component 132 and the second component 133, respectively. The first protrusion 131a and the second protrusion 131b are configured to protrude outward from the body of the bracket 131, for example, in a direction perpendicular to the body, and are spaced apart to form a first channel 131e between them. This channel provides passage for the elevator guide rail 109 to pass through, so that during use, the elevator guide rail 109 can be engaged, fixed, or disengaged from both sides by operating the first component 132 located on the first protrusion 131a and the second component 133 located on the second protrusion 131b, respectively. The first protrusion 131a and the second protrusion 131b can be integrally manufactured with the body of the bracket 131 using processes such as casting or machining, or they can be manufactured separately and then fixed to the body of the bracket 131 using connection methods such as welding or screwing. For example… Figure 5 As shown, the first protrusion 131a and the second protrusion 131b can be optionally arranged to maintain a parallel relationship. After the device 130 is installed on the car frame column 104, the first protrusion 131a and the second protrusion 131b can maintain a parallel relationship with the elevator guide rail 109, and the first component 132 and the second component 133 can be in the same horizontal plane.

[0064] As an optional configuration, the bracket 131 can be constructed to have a first extension 131c and a second extension 131d, which can extend outward from the body of the bracket 131, for example, along such a line after the bracket 131 is installed in place. Figure 2 The vertical direction Z (i.e., the length direction of the elevator guide rail or car frame column after installation) is extended as shown, and the first extension 131c and the second extension 131d are arranged at intervals to form a second channel 131f between them, so that the elevator guide rail 109 can pass through the channel without causing interference. The contact 135, which will be discussed later, can be installed on the first extension 131c or the second extension 131d so that it can be used to engage with the corresponding mating part 136.

[0065] The device 130 is provided with a pressure regulating section, which can be used to adjust the contact pressure between the roller guide shoe 110 and the elevator guide rail 109, for example, to reduce or eliminate the effect of static pressure on the roller guide shoe 110 when needed. As an example, as used in the embodiments herein, the pressure regulating section may include a contact member 135 and a mating member 136, which will be described below.

[0066] The contact 135 can be mounted to the bracket 131 by any suitable method, such as detachable connection (e.g., bolts, screws), welding, etc., for example, fixedly connected to the first extension 131c or the second extension 131d discussed above. The contact 135 can optionally be configured so that it does not contact the elevator guide rail 109 during normal operation of the elevator system. This can be achieved by arranging the contact 135 with a preset gap from the elevator guide rail 109. The specific value of this gap can be set or adjusted as needed, for example, optionally set in the range of 1-10mm, such as 2mm, 3mm, 4mm, 5mm, 8mm, etc. Furthermore, in one or more embodiments, the contact 135 can be arranged to contact the elevator guide rail 109 during normal operation of the elevator system, thereby bearing some of the contact pressure and reducing the load on the roller guide shoe 110, etc. Depending on the application requirements, the contact element 135 can be configured with any feasible structure, shape, and size. For example, it can be made of one or more rolling elements, or it can be made of one or more materials as needed. For example, in some applications, rigid materials such as steel or iron can be used alone, while in other applications, elastic or plastic materials can be wrapped around the structure made of rigid materials to further bring positive effects such as cushioning, noise reduction, and improved stability.

[0067] The mating component 136 can be installed at a preset position on the elevator guide rail 109 to mate with the corresponding contact component 135. For example, the mating component 136 can be installed at one or more such preset positions in any suitable manner, such as detachable connection (e.g., bolts, screws), welding fixation, etc. For example, the distance between the preset position P1 (or P2) and the top (or bottom) of the elevator shaft 117 is not less than a preset value, such as 1m or any other suitable value. It should be noted that different preset positions can be designed as needed on different car frame columns 104.

[0068] Thus, under the conditions required for the application, such as when the elevator system is currently idle (e.g., exceeding a settable time period, such as 10 minutes, 20 minutes, or other values) or in a stopped state (e.g., when the elevator system receives a stop instruction from the operator, or enters a preset time period, such as midnight to 6:00 AM), the elevator car 103 can be moved to a position close to the preset position discussed above (e.g., the aforementioned preset position P1) and stopped. At this time, the contact member 135 can contact and press against the corresponding mating member 136, thereby generating a force F between them and applying it to the contact member 135. Figure 8This allows the roller guide shoes 110 (more specifically, one or more rollers 110a in the roller guide shoes 110) that were originally in contact with the elevator guide rail 109 and thus subjected to pressure to now be able to disengage from the elevator guide rail 109, or to reduce the contact pressure between the roller guide shoes 110 and the elevator guide rail 109 compared to the previous situation. That is, it can at least reduce the static pressure that the roller guide shoes 110 are subjected to when the elevator car is stopped, thereby protecting the roller guide shoes 110 from or mitigating the adverse effects of local deformation caused by pressure on the contact surface, which would lead to accelerated wear, noise and vibration.

[0069] Depending on the application requirements, the mating parts 136 and the contact parts 135 can be designed and configured accordingly to achieve different pressure adjustment effects on the roller guide shoe 110. For example, different forces F can be generated. These forces may have different magnitudes, which will have different effects on the adjustment of the contact pressure borne by the roller guide shoe 110.

[0070] For example, the mating member 136 can be configured with different segments, such as two, three, or more segments, so that the contact member 135 can generate different magnitudes of force F when it contacts these different segments. For example, the mating member 136 can be optionally configured to have two segments, namely a first segment and a second segment, which can be arranged along the length of the elevator guide rail 109. In actual use, if the contact member 135 contacts the first segment, a first force will be generated, and if the contact member 135 contacts the second segment, a second force will be generated. The second force can be greater than the first force. Thus, as an alternative, by correspondingly designing the magnitudes of the first and second forces, different contact conditions between the roller guide shoe 110 and the elevator guide rail 109 can be controlled to better achieve different desired effects. For example, under the first force, a relatively small gap can be maintained between the roller guide shoe 110 and the elevator guide rail 109, while under the second force, a relatively large gap can be maintained. Considering that the roller guide shoe 110 itself may continuously wear down during long-term use, this ability to adaptably and flexibly adjust and provide the required gap is very advantageous.

[0071] To further illustrate, for example... Figure 6As an example, the mating member 136 can be configured with three sections, wherein the first section 136a and the third section 136c are respectively arranged at both ends of the second section 136b. The first section 136a can be provided with, for example, a wedge-shaped guide portion, that is, a cross section that gradually increases towards the second section 136b, so as to more smoothly guide the contact member 135 to make a pressing contact with the mating member 136. The third section 136c can adopt the same or similar configuration as the first section 136a. In addition, the second section 136b can be configured such that its surface is parallel to the surface of the elevator guide rail 109. In this way, when the elevator car 103 moves close to the preset position of the mating part 136 and finally stops, the contact part 135 can first contact the first section 136a, and then enter a state of stable pressing contact with the second section 136b. At this time, the force F generated by the pressing contact can be applied to the contact part 135 smoothly and evenly, which is more conducive to maintaining the stability of the system and avoiding deformation or damage to the contact part due to poor force.

[0072] exist Figure 9 The document illustrates basic steps of a method according to this disclosure, which can be used for the installation and pressure adjustment of roller guide shoes. Specifically, this method embodiment may include the following steps:

[0073] In step S100, the device for roller guide shoe installation and pressure adjustment provided in this disclosure can be installed in the elevator system. The configuration, operation and technical advantages of the device of this disclosure have been discussed in detail above with specific examples. Please refer to the above content.

[0074] In step S200, the positioning part of the above-mentioned device is operated to enter the first state, thereby fixing the positioning of the elevator car frame column relative to the elevator guide rail, so as to provide an installation reference for assembling the roller guide shoe onto the frame column.

[0075] In step S300, based on the positioning reference already implemented in step S200, the roller guide shoe can be installed onto the car frame column very conveniently, accurately and efficiently. After the installation of the roller guide shoe is completed, the positioning part can be reversed, that is, the positioning of the car frame column relative to the elevator guide rail, which was previously fixed by operating the positioning part, can be released, so that the positioning part switches from the first state to the second state.

[0076] In step S400, when the elevator system is in a preset state (such as an idle state or a stopped state, which can be detected or judged by, for example, the controller 115), the elevator car can be stopped at a preset position on the elevator guide rail by moving close to the mating part in the above-mentioned device, so that the mating part and the contact part make abutting contact, thereby forcing the adjustment of the current contact pressure between the roller guide shoe and the elevator guide rail, so that the contact pressure can be eliminated or reduced.

[0077] Those skilled in the art will understand that, since the foregoing has already described in detail the technical aspects of the device for installing and adjusting roller guide shoes, the roller guide shoes, the car frame columns, etc., including their configuration, installation, and use, different magnitudes of force can be generated by making different sections of the contacting parts and mating parts into contact to meet the needs of different application scenarios; or, for example, the mating parts and contacting parts can be pressed together to disengage one or more target rollers in the roller guide shoes that are to be protected from the elevator guide rail, thereby creating a gap between the target rollers and the elevator guide rail. Therefore, one can directly refer to the specific descriptions in the corresponding sections above, which can lead to more possible steps and settings of the method disclosed herein, and therefore will not be repeated here.

[0078] The above examples are merely illustrative of the apparatus and method for installing and adjusting roller guide shoes, as well as the elevator system according to this disclosure. These examples are only for illustrating the principles and implementation methods of this disclosure and are not intended to limit the scope of this disclosure. Various modifications and improvements can be made by those skilled in the art without departing from the scope of this disclosure. Therefore, all equivalent technical solutions should fall within the scope of this disclosure and be defined by the claims of this disclosure.
