Description

Technical Field

[0001] This application relates to the technical field of elevator installation, and in particular to an adjustment fixture for an elevator car frame. Background Technology

[0002] The car frame is the component in an elevator used to support the weight of the car. After the car frame is manufactured in the factory, it is transported to the installation site in the form of disassembled parts. Then, the installers set up a scaffold in the shaft and assemble the car frame in the shaft. Due to the large size of the car frame, it is difficult for the installers to ensure the overall assembly accuracy of the car frame. In addition, the narrow and dark environment in the shaft also increases the difficulty of the installation work, resulting in low installation efficiency and long construction period. Summary of the Invention

[0003] Therefore, it is necessary to provide an adjustment tooling for elevator car frames to address the problems of low installation efficiency and long construction period in traditional technologies.

[0004] The technical solution is as follows:

[0005] One embodiment provides an adjustment fixture for an elevator car frame, the elevator car frame including a first column, a second column, a first crossbeam, and a second crossbeam, the first column, the first crossbeam, the second column, and the second crossbeam being connected end-to-end to form the car frame body, a first guide shoe being provided at one end of the first crossbeam, a second guide shoe being provided at the other end of the first crossbeam, a third guide shoe being provided at one end of the second crossbeam, and a fourth guide shoe being provided at the other end of the second crossbeam, the adjustment fixture for the elevator car frame including:

[0006] Mounting base;

[0007] A first clamping assembly and a second clamping assembly are spaced apart on the mounting base along a first direction of the car frame body. The first clamping assembly is used to clamp or release the first upright, and the second clamping assembly is used to clamp or release the second upright. The first clamping assembly and the second clamping assembly are capable of moving closer to or further away from each other.

[0008] A first guide rail simulation component and a second guide rail simulation component are capable of moving closer to or further away from each other. The first guide rail simulation component is used for guiding and engaging with the first guide shoe and the third guide shoe, and the second guide rail simulation component is used for guiding and engaging with the second guide shoe and the fourth guide shoe.

[0009] The aforementioned adjustment fixture for the elevator car frame is used by first pre-assembling the first column, second column, first crossbeam, second crossbeam, first guide shoe, second guide shoe, third guide shoe, and fourth guide shoe into the car frame body. The distance between the first clamping assembly and the second clamping assembly is adjusted, and the first column of the car frame body is clamped using the first clamping assembly on the mounting base. Then, the second clamping assembly clamps the second column of the car frame body to achieve initial positioning of the car frame body. Subsequently, the distance between the first guide rail simulation assembly and the second guide rail simulation assembly is adjusted so that the distance between them is equal to the distance between the two guide rails in the elevator shaft. This allows the first and second guide rail simulation assemblies to simulate the two guide rails in the elevator shaft. After adjustment, the first and third guide shoes on one side of the car frame body in the first direction are guided to the first guide rail simulation assembly. Then, the second and fourth guide shoes on the other side of the car frame body in the first direction are guided to the second guide rail simulation assembly. To achieve proper guidance and coordination, the workers then adjust the assembly position information between the first upright, first crossbeam, second upright, and second crossbeam to ensure that the horizontal and vertical indicators of the elevator car body meet the installation requirements. During the adjustment process, the first and second clamping components can move closer or further apart to adapt to changes in the positional relationship between the first and second uprights. After adjustment, the workers record the assembly position information between the first upright, first crossbeam, second upright, and second crossbeam, disassemble the elevator car body, and transport it to the hoistway. Using the recorded assembly position information, the first upright, first crossbeam, second upright, and second crossbeam are quickly assembled. Compared with traditional technology, the above-mentioned adjustment fixture for the elevator car body can adjust and record the assembly position information between the first upright, first crossbeam, second upright, and second crossbeam before the elevator car body is installed in the hoistway. After the elevator car body is transported to the construction site, it is quickly assembled using the previously recorded assembly position information, thereby improving the installation efficiency of the elevator car body.

[0013] In one embodiment, the guide includes a first guide bar and a second guide bar, both of which extend along a first direction of the car frame body. The first guide bar and the second guide bar are parallel to each other and spaced apart on the mounting base along a second direction of the car frame body, the second direction being perpendicular to the first direction. The first guide bar, the mounting base, and the second guide bar surround each other to form the guide groove.

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0029] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0030] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0031] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0032] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0033] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0034] Please see Figure 1 and Figure 4 The elevator frame includes a first column 110, a second column 120, a first crossbeam 130, and a second crossbeam 140. These columns are connected end-to-end to form the frame body 100. A first guide shoe 151 is located at one end of the first crossbeam 130, and a second guide shoe 152 is located at the other end. A third guide shoe 153 is located at one end of the second crossbeam 140, and a fourth guide shoe 154 is located at the other end. The frame body 100 is rectangular, and the first guide shoe 151, second guide shoe 152, third guide shoe 153, and fourth guide shoe 154 are located at the four corners of the rectangular frame body 100.

[0035] Furthermore, two guide rails are usually installed opposite each other in the elevator shaft. When the car frame body 100 is installed in the elevator shaft, the first guide shoe 151 and the third guide shoe 153 located on one side of the car frame body 100 along the first direction are guided and engaged with one of the guide rails in the shaft. The second guide shoe 152 and the fourth guide shoe 154 located on the other side of the car frame body 100 along the first direction are guided and engaged with the other guide rail in the shaft. The car is installed on the car frame body 100 so that the car can be moved by the car frame body 100.

[0036] For illustrative purposes, the first direction refers to the width direction of the car frame body 100, that is... Figure 1 In direction A.

[0037] However, due to the large size of the car frame body 100, after the car frame body 100 is manufactured in the factory, it is usually transported to the installation site in three parts: the first column 110, the second column 120, the first crossbeam 130, and the second crossbeam 140. Then, the workers set up a scaffold in the elevator shaft to assemble the car frame body 100 in the elevator shaft. It is difficult for the installers to ensure the overall assembly accuracy of the car frame, and the narrow and dark environment in the shaft also increases the difficulty of the installation work, resulting in low installation efficiency of the car frame body 100 and thus a long elevator installation period.

[0038] Please see Figures 1 to 2 One embodiment of this application provides an adjustment fixture for an elevator car frame, including a mounting base 210, a first clamping component 300, a second clamping component 400, a first guide rail simulation component 500, and a second guide rail simulation component 600. The first clamping component 300 and the second clamping component 400 are spaced apart on the mounting base 210 along a first direction of the car frame body 100. The first clamping component 300 is used to clamp or release the first column 110, and the second clamping component 400 is used to clamp or release the second column 120. The first clamping component 300 and the second clamping component 400 can move closer to or further away from each other. The first guide rail simulation component 500 and the second guide rail simulation component 600 can move closer to or further away from each other. The first guide rail simulation component 500 is used for guiding and engaging with the first guide shoe 151 and the third guide shoe 153, and the second guide rail simulation component 600 is used for guiding and engaging with the second guide shoe 152 and the fourth guide shoe 154.

[0039] The aforementioned adjustment fixture for the elevator car frame is used by first pre-assembling the first column 110, second column 120, first crossbeam 130, second crossbeam 140, first guide shoe 151, second guide shoe 152, third guide shoe 153, and fourth guide shoe 154 into the car frame body 100. The distance between the first clamping assembly 300 and the second clamping assembly 400 is adjusted, and the first column 110 of the car frame body 100 is clamped using the first clamping assembly 300 on the mounting base 210. Then, the second clamping assembly 400 is used to clamp the second column 120 of the car frame body 100 to achieve initial positioning of the car frame body 100. Subsequently... The distance between the first guide rail simulation component 500 and the second guide rail simulation component 600 is adjusted so that the distance between them is equal to the distance between the two guide rails in the elevator shaft. This allows the first and second guide rail simulation components 500 and 600 to simulate the two guide rails in the elevator shaft. After adjustment, the first guide shoe 151 and the third guide shoe 153 on one side of the car frame body 100 in the first direction are guided to engage with the first guide rail simulation component 500. Then, the second guide shoe 152 and the fourth guide shoe 153 on the other side of the car frame body 100 in the first direction are guided to engage with the first guide rail simulation component 500. 4. Guided engagement is achieved between the first upright 110, the first crossbeam 130, the second upright 120, and the second crossbeam 140. At this point, the workers adjust the assembly position information between the first upright 110, the first crossbeam 130, the second upright 120, and the second crossbeam 140 to ensure that the horizontal and vertical indicators of the car frame body 100 meet the installation requirements. During the adjustment process, the first clamping assembly 300 and the second clamping assembly 400 can move closer or further apart to accommodate changes in the positional relationship between the first upright 110 and the second upright 120. After adjustment, the workers then perform assembly adjustments between the first upright 110, the first crossbeam 130, the second upright 120, and the second crossbeam 140. The position information is recorded, the car frame body 100 is disassembled and transported to the shaft, and the first column 110, the first crossbeam 130, the second column 120 and the second crossbeam 140 are quickly assembled using the recorded assembly position information. Compared with traditional technology, the above-mentioned adjustment fixture for the elevator car frame can adjust and record the assembly position information between the first column 110, the first crossbeam 130, the second column 120 and the second crossbeam 140 before the car frame body 100 is installed in the shaft. After the elevator car frame is transported to the construction site, it is quickly assembled using the previously recorded assembly position information, thereby improving the installation efficiency of the car frame.

[0040] For illustrative purposes, the first column 110, the first crossbeam 130, the second column 120, and the second crossbeam 140 are typically assembled using bolts. Figure 4In the illustrated embodiment, several screw holes are provided at both ends of the first column 110, the second column 120, the first crossbeam 130, and the second crossbeam 140. Bolts are inserted through these screw holes to assemble the car frame body 100. However, due to the large size of the car frame body 100, in order to ensure that the car frame body 100 meets the requirements for overall straightness and flatness after installation, in conventional technology, workers need to adjust the assembly of the car frame body 100 inside the shaft. For example, workers need to adjust the bolts inside the shaft to ensure that they pass through the correct screw holes. The previous method of installing the elevator car frame 100 in the hoistway is difficult due to the complexity of the installation process. In this application, before installing the car frame body 100 into the hoistway, the guide rails in the hoistway are simulated using adjustment tools, and the assembly effect between the first column 110, the first crossbeam 130, the second column 120, and the second crossbeam 140 is adjusted to ensure that the car frame body 100 meets the requirements for straightness and flatness. The assembly position information, such as the bolt holes through which the screws pass and the placement of the washers, is recorded. After the elevator car frame is transported to the construction site, the previously recorded assembly position information is used for rapid assembly, thereby improving the installation efficiency of the car frame.

[0041] For example, the assembly location information can be recorded by marking it with white paint or by saving image information (such as taking a picture), without any specific limitation here.

[0042] In one embodiment, see Figure 1 and Figure 2Before adjusting the car frame body 100 using the adjustment fixture, the car frame body 100 is pre-assembled using relevant data of the elevator shaft provided by the customer. The pre-assembled car frame body 100 is then clamped by the first clamping assembly 300 and the second clamping assembly 400 to achieve initial positioning of the car frame body 100. Subsequently, the positions of the first guide rail simulation assembly 500 and the second guide rail simulation assembly 600 are adjusted using the relevant data of the elevator shaft provided by the customer, so that their positions are the same as the positions of the two guide rails in the elevator shaft. At this time, the installation positions of the first guide shoe 151 and the second guide shoe 152 on the first crossbeam 130 are adjusted, and the installation positions of the third guide shoe 153 and the fourth guide shoe 154 on the second crossbeam 140 are adjusted so that the installation positions of the four guide shoes match those of the first guide rail simulation assembly 500 and the second guide rail simulation assembly 600. Then, the first clamping assembly 300 and the second... The clamping assembly 400 releases the first column 110 and the second column 120 respectively to adjust the installation position of the first column 110 and the second column 120. After adjustment, the distance between the first clamping assembly 300 and the second clamping assembly 400 is adjusted so that the position of the first clamping assembly 300 and the second clamping assembly 400 matches the adjusted position of the first column 110 and the second column 120. The first clamping assembly 300 and the second clamping assembly 400 are used to clamp and position the first column 110 and the second column 120 respectively. Then, the bolt insertion position, the installation position and quantity of the gaskets on the first column 110, the second column 120, the first crossbeam 130 and the second crossbeam 140 are recorded. The car frame body 100 is disassembled and transported to the hoistway. The recorded assembly position information is used to quickly assemble the first column 110, the first crossbeam 130, the second column 120, the second crossbeam 140 and each guide shoe.

[0043] Furthermore, the rolling fit between the guide shoe wheel and the first guide rail simulation assembly 500 is adjusted by adjusting the springs on the first guide shoe 151 and the second guide shoe 152, so that the first guide shoe 151 and the second guide shoe 152 can match the first guide rail simulation assembly 500; the third guide shoe 153 and the fourth guide shoe 154 are similar to the first guide shoe 151 and the second guide shoe 152, and will not be described in detail here.

[0044] Please see Figure 1 and Figure 2 In one embodiment, the mounting base 210, the first guide rail simulation component 500, and the second guide rail simulation component 600 are separately arranged and have no connection relationship, so as to adjust the setting position of the mounting base 210, the first guide rail simulation component 500, and the second guide rail simulation component 600 by the size of the car frame.

[0045] Furthermore, the first guide rail simulation component 500 includes a section of a guide rail of the same model as the guide rail in the elevator shaft, and the second guide rail simulation component 600 includes a section of a guide rail of the same model as the guide rail in the elevator shaft, thereby improving the simulation effect of the first guide rail simulation component 500 and the second guide rail simulation component 600 on the guide rail in the shaft.

[0046] Please see Figure 1 and Figure 4 In one embodiment, the first column 110 includes at least two first columns 111, all of which are coaxially arranged. Each first column 111 has a first end 1111 and a second end 1112 opposite to each other. In two adjacent first columns 111, the first end 1111 of one first column 111 is connected to the second end 1112 of the other first column 111. The first end 1111 of one first column 111 at one end of the first column 110 is connected to one end of the first crossbeam 130, and the second end 1112 of the first column 111 at the other end of the first column 110 is connected to one end of the second crossbeam 140. The second column 120 includes at least two second columns 121, each corresponding to one of the first columns 111. All second columns 121 are coaxially arranged, and each second column 121 has a third end 1211 and a fourth end 1212 opposite to each other. Of the two second columns 121, the third end 1211 of one second column 121 is connected to the fourth end 1212 of the other second column 121. The third end 1211 of the second column 121 located at one end of the second column 120 is connected to the end of the first crossbeam 130 away from the first column 111. The fourth end 1212 of the second column 121 located at the other end of the second column 120 is connected to the end of the second crossbeam 140 away from the first column 111. At least two mounting bases 210 are provided and are arranged one-to-one with the first columns 111. At least two first clamping assemblies 300 are provided and are arranged one-to-one with the mounting bases 210. At least two second clamping assemblies 400 are provided and are arranged one-to-one with the mounting bases 210. All the first clamping assemblies 300 are used to clamp the first columns 111 one-to-one, and all the second clamping assemblies 400 are used to clamp the second columns 121 one-to-one.

[0047] When the elevator car has at least two floors, the size of the car frame body 100 will also increase accordingly. Therefore, the height of the first column 110 and the second column 120 of the car frame body 100 will also be higher. In order to facilitate the transportation of disassembled parts after the production of the car frame body 100, the first column 110 is divided into at least two first columns 111 and the second column 120 is divided into at least two second columns 121. At least two first clamping components 300 and at least two second clamping components 400 are used to clamp the corresponding first columns 111 and second columns 121 respectively, thereby adjusting and recording the assembly position information between the first column 111, the second column 121, the first crossbeam 130 and the second crossbeam 140, so as to facilitate the rapid installation of the car frame body 100 on site using the recorded position. The implementation process is convenient and improves the installation efficiency.

[0048] For explanation, please refer to Figure 4 The two adjacent first columns 111 are provided with several screw holes at their joints and are connected by a connecting plate. The connecting plate is also provided with several through holes. By passing several bolts through the through holes on the connecting plate and the screw holes on the first column 111 in sequence, the connection between the two adjacent first columns 111 is achieved. The connection process between the two adjacent second columns 121 is similar to that of the first column 110, and will not be described in detail here.

[0049] Furthermore, taking the first column 110 as an example, the two adjacent first columns 111 are connected by several bolts passing through the through holes on the connecting plate and the screw holes on the first column 111. During this process, in order to ensure the overall straightness and flatness between the two adjacent first columns 111, it is necessary to use adjustment tools to adjust the position of the screw holes on the connecting plate through which the bolts pass and the position of the screw holes on the first column 111. If necessary, shims are added between the bolts and the screw holes. After the adjustment is completed, the position of the through holes on the connecting plate for passing the bolts, the position of the screw holes on the first column 111, and the number of shims added are recorded as assembly position information. Then, the first column 110 is quickly assembled in the wellbore using the recorded assembly position information. The assembly method of the second column 120 is similar to that of the first column 110, and will not be described in detail here.

[0050] In other embodiments, a connecting beam can be used instead of a connecting plate, which will not be elaborated here.

[0051] Specifically Figure 4In the embodiment shown, the car frame is used for a double-deck elevator. The first column 110 includes two first columns 111, and the second column 120 includes two second columns 121. The overall height of the car frame can reach more than 10 meters. In other embodiments, the first column 110 may also include more than two first columns 111, and the second column 120 may also include more than two second columns 121, which will not be elaborated here.

[0052] Please see Figure 2 and Figure 3 In one embodiment, the adjustment fixture for the elevator car frame further includes a guide assembly 700, which is disposed on the mounting base 210. The first clamping assembly 300 is guided and engaged with the guide assembly 700 so that the first clamping assembly 300 can move closer to or further away from the second clamping assembly 400.

[0053] The first clamping component 300 can move on the mounting base 210 under the action of the guide component 700, so that the first clamping component 300 can move closer to or further away from the second clamping component 400, so that the operator can adjust the positional relationship between the first column 110 and the second column 120, and the adjustment process is stable and reliable.

[0054] In one embodiment, the guide assembly 700 includes a guide member and a guide mating member. The guide member is disposed on the mounting base 210 and has a guide groove 730. The guide groove 730 extends along a first direction of the car frame body 100. The guide mating member is disposed on the guide groove 730 and can reciprocate along the extension direction of the guide groove 730. The first clamping assembly 300 is connected to the guide mating member.

[0055] The guide fitting can reciprocate along the extension direction of the guide groove 730 to drive the first clamping assembly 300 to reciprocate along the first direction of the car frame body 100, thereby enabling the first clamping assembly 300 to move closer to or further away from the second clamping assembly 400, so that the operator can adjust the positional relationship between the first column 110 and the second column 120. The adjustment process is stable and reliable.

[0056] Please see Figure 3 In one embodiment, the guide includes a first guide bar 711 and a second guide bar 712. Both the first guide bar 711 and the second guide bar 712 extend along a first direction of the car frame body 100. The first guide bar 711 and the second guide bar 712 are parallel to each other and are spaced apart on the mounting base 210 along a second direction of the car frame body 100. The second direction is perpendicular to the first direction. The first guide bar 711, the mounting base 210 and the second guide bar 712 surround each other to form a guide groove 730.

[0057] The first guide bar 711 and the second guide bar 712 are arranged parallel to and spaced apart along the second direction of the car frame body 100, thereby forming a guide groove 730 extending along the first direction of the car frame body 100 with the mounting base 210. The guide mating member can reciprocate along the guide groove 730 to realize the mutual approach or distance between the first clamping assembly 300 and the second clamping assembly 400, which has low implementation cost and reliable movement process.

[0058] For illustrative purposes, the second direction refers to the height direction of the car frame body 100, that is... Figure 1 In the B direction.

[0059] Please see Figure 3 In one embodiment, the first clamping assembly 300 includes a base 310 and a clamping member 320. The guiding engagement member includes a first guide block 721 and a second guide block 722. The first guide block 721 is disposed on one side of the base 310 along the second direction of the car frame body 100, and the second guide block 722 is disposed on the other side of the base 310 along the second direction of the car frame body 100. The first guide bar 711 has a first sliding groove 713 on the side facing the second guide bar 712, and the second guide bar 712 has a second sliding groove 714 on the side facing the first guide bar 711. The first guide block 721 is guided and engaged with the first sliding groove 713, and the second guide block 722 is guided and engaged with the second sliding groove 714. The clamping member 320 is disposed on the base 310 and is used to clamp or release the first column 110.

[0060] The first guide block 721 and the second guide block 722 are respectively disposed on opposite sides of the base 310 along the second direction of the car frame body 100, and the first guide block 721 and the second guide block 722 can move in the first slide groove 713 of the first guide bar 711 and the second slide groove 714 of the second guide bar 712 respectively, so as to drive the clamping member 320 on the base 310 to move. This arrangement can prevent the first guide block 721 and the second guide block 722 from falling out of the guide groove 730, thereby improving the movement stability and reliability of the base 310.

[0061] Further, please refer to Figure 3 The cross-sectional shape of the first guide bar 711 and the second guide bar 712 is L-shaped, so that a first groove 713 is formed on the first guide bar 711 and a second groove 714 is formed on the second guide bar 712.

[0062] In one embodiment, the base 310 is formed by bending or stamping sheet metal.

[0063] In one embodiment, the clamping member 320 includes a first clamping part and a second clamping part, which can move closer to or further away from each other to clamp or release the first column 110.

[0064] Furthermore, the specific structure of the second clamping component 400 is similar to that of the first clamping component 300, except that the first clamping component 300 can be moved by the guide component 700, while the second clamping component 400 is fixed to one end of the mounting base 210; in other embodiments, the second clamping component 400 can also be set to a movable form, which will not be described in detail here.

[0065] Please see Figure 3 In one embodiment, the adjustment fixture for the elevator car frame further includes a first bolt 811. The first guide strip 711 has at least two first screw holes along the first direction of the car frame body 100. The first bolt 811 is used to be screwed into any one of the first screw holes and abuts against the first guide block 721.

[0066] The first bolt 811 can be screwed into the first screw hole and abut against the first guide block 721, so that friction is generated between the first bolt 811 and the first guide block 721, thereby restricting the movement of the first guide block 721 in the first slide groove 713, and thus realizing the positioning of the clamping member 320.

[0067] As an explanation, when the base 310 moves to the designated position along the extension direction of the guide groove 730, the first bolt 811 is screwed into a first screw hole corresponding to that position, so that the first bolt 811 can pass through the first screw hole and abut against the first guide block 721, thereby restricting the movement of the first guide block 721 in the first slide groove 713.

[0068] Please see Figure 3 As an embodiment that can be implemented simultaneously with the above embodiments, the adjustment fixture for the elevator car frame also includes a second bolt 812. The second guide strip 712 has at least two second screw holes along the first direction of the car frame body 100. The second bolt 812 is used to be screwed into any one of the second screw holes and abuts against the second guide block 722.

[0069] The second bolt 812 can pass through the second screw hole and abut against the second guide block 722, so that friction is generated between the second bolt 812 and the second guide block 722, thereby restricting the movement of the second guide block 722 in the second slide groove 714, and thus realizing the positioning of the clamping member 320.

[0070] As an explanation, when the base 310 moves to the designated position along the extension direction of the guide groove 730, the second bolt 812 is screwed into a second screw hole corresponding to that position, so that the second bolt 812 can pass through the second screw hole and abut against the second guide block 722, thereby restricting the movement of the first guide block 721 in the first slide groove 713.

[0071] Please see Figures 5 to 6In one embodiment, the first guide rail simulation assembly 500 includes a first bracket 510, a first connector 520, a first guide rail simulation component 530, a second bracket, a second connector, and a second guide rail simulation component. The first bracket 510 has a first mounting hole 511, the first connector 520 passes through the first mounting hole 511 and is connected to the first guide rail simulation component 530, the second bracket is spaced apart from the first bracket 510 along a second direction of the car frame body 100, the second bracket has a second mounting hole, the second connector passes through the second mounting hole and is connected to the second guide rail simulation component, the first guide rail simulation component 530 is used for guiding and engaging with the first guide shoe 151, and the second guide rail simulation component is used for guiding and engaging with the third guide shoe 153.

[0072] The first guide rail simulation component 530 is mounted on the first bracket 510 via the first connector 520, and the second guide rail simulation component is mounted on the second bracket via the second connector. In this way, the operator can adjust the positional relationship between the first bracket 510 and the second bracket to adapt to the height of the elevator car frame (i.e., the distance between the first crossbeam 130 and the second crossbeam 140), and thus adapt to the positional relationship between the first guide shoe 151 and the third guide shoe 153 on the car frame body 100. The first guide rail simulation component 530 and the second guide rail simulation component can respectively achieve guiding cooperation with the first guide shoe 151 and the third guide shoe 153, thereby simulating the guide rail in the shaft through the first guide rail simulation component 530 and the second guide rail simulation component. The implementation cost is low, the footprint is small, and the adjustment process is convenient.

[0073] Furthermore, at least two first mounting holes 511 are provided. In this way, different first mounting holes 511 can be selected according to the model of the first guide rail simulation component 530 to realize the connection between the first guide rail simulation component 530 and the first bracket 510, thereby realizing the simulation of different models of guide rails and improving the applicability of the adjustment fixture. The second mounting hole is similar to the first mounting hole 511, and will not be described in detail here.

[0074] In some embodiments, the first connector 520 may be a bolt for fixing the guide rail. In other embodiments, the first connector 520 may also be a clamp or the like, which will not be described in detail here.

[0075] In one embodiment, the second guide rail simulation assembly 600 includes a third bracket, a third connector, a third guide rail simulation component, a fourth bracket, a fourth connector, and a fourth guide rail simulation component. The third bracket has a third mounting hole, the third connector passes through the third mounting hole and is connected to the third guide rail simulation component, the fourth bracket is spaced apart from the third bracket along the second direction of the car frame body 100, the fourth bracket has a fourth mounting hole, the fourth connector passes through the fourth mounting hole and is connected to the fourth guide rail simulation component, the third guide rail simulation component is used for guiding engagement with the second guide shoe 152, and the fourth guide rail simulation component is used for guiding engagement with the fourth guide shoe 154.

[0076] The third guide rail simulation component is mounted on the third support via the third connector, and the fourth guide rail simulation component is mounted on the fourth support via the fourth connector. In this way, the operator can adjust the positional relationship between the third and fourth supports to adapt to the height of the elevator car frame (i.e., the distance between the first crossbeam 130 and the second crossbeam 140), and thus adapt to the positional relationship between the second guide shoe 152 and the fourth guide shoe 154 on the car frame body 100. The third and fourth guide rail simulation components can respectively achieve guiding cooperation with the second guide shoe 152 and the fourth guide shoe 154, thereby simulating the guide rail in the shaft through the third and fourth guide rail simulation components. The implementation cost is low, the footprint is small, and the adjustment process is convenient.

[0077] Furthermore, at least two third mounting holes are provided. This allows for the selection of different third mounting holes based on the model of the third guide rail simulator to achieve the connection between the third guide rail simulator and the third bracket, thereby simulating different models of guide rails and improving the applicability of the adjustment fixture; for example, in Figure 6 In the embodiment shown, the guide rail simulated by the guide rail simulator is a T-type guide rail; the fourth mounting hole is similar to the third mounting hole, and will not be described again here.

[0078] When adjusting the tooling during construction, it is also necessary to use a ruler and plumb line to confirm the position of the first guide rail simulation component 530, the second guide rail simulation component, the third guide rail simulation component, and the fourth guide rail simulation component, and whether they are on the same horizontal plane. It is also necessary to confirm the distance between the first guide rail simulation component 530, the second guide rail simulation component, the third guide rail simulation component, and the fourth guide rail simulation component, etc., to ensure the simulation effect of the guide rail simulation components.

[0079] In some embodiments, the first connector 520, the second connector, the third connector, and the fourth connector can be bolts for fixing the guide rail. In other embodiments, the first connector 520, the second connector, the third connector, and the fourth connector can also be clamps, etc., which will not be described in detail here.

[0080] Please see Figure 1In one embodiment, the first guide rail simulation assembly 500 further includes a first mounting platform 540 and a second mounting platform 550, wherein the first mounting platform 540 is equipped with a first bracket 510 and the second mounting platform 550 is equipped with a second bracket.

[0081] Please see Figure 1 In one embodiment, the second guide rail simulation assembly 600 further includes a third mounting platform 610 and a fourth mounting platform 620, wherein the third mounting platform 610 is equipped with a third bracket and the fourth mounting platform 620 is equipped with a fourth bracket.

[0082] Furthermore, the first bracket 510, the second bracket, the third bracket and the fourth bracket are all equipped with clamps to clamp the first column 110 and the second column 120 to ensure clamping stability.

[0083] In one embodiment, the mounting base 210, the first bracket 510, the second bracket, the third bracket, and the fourth bracket are all welded from a single piece of metal steel, and the reference plane of the mounting base 210, the first bracket 510, the second bracket, the third bracket, and the fourth bracket is 800-1000mm above the ground. Before adjusting the car frame body 100, C-type shims are used to calibrate the reference plane of each platform.

[0084] Please see Figure 2 In one embodiment, the adjustment fixture for the elevator car frame further includes an auxiliary support 220, which supports the car frame body 100 when the first clamping assembly 300 and the second clamping assembly 400 loosen the car frame body 100.

[0085] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0086] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
