Description

Technical Field

[0001] The utility model relates to the technical field of elevator accessories, and particularly relates to an adjustable elevator car bracket. Background Art

[0002] Elevators are indispensable equipment in modern buildings. The installation and fixation of elevators are extremely important for the safe and stable operation of elevators. At present, most vertical elevators are provided with a linear guide rail structure on the side wall of the hoistway. By installing a sliding structure on the side wall of the car that cooperates with the guide rail, the limit of the elevator car moving up and down linearly along the elevator shaft is realized. This design generally supports and installs the guide rail on the hoistway wall through an elevator car bracket. However, due to the high operating speed and large impact force of the elevator, there are relatively high requirements for the strength and installation stability of the elevator car bracket.

[0003] The commonly used side guide rail bracket designs on the market now are all fixed to the corresponding positions through methods such as screw cooperation and welding. The quality of its stability, safety, and connection strength largely depends on the design of the installation holes on the elevator side guide rail bracket. However, due to the long linear structure of the elevator shaft itself, in order to ensure the straightness of the guide rail, there are quite strict requirements for its installation technology. Generally, the guide rails are installed section by section through guide rail brackets and then connected to each other to form a complete whole. Considering the working intensity, the installation of the guide rail brackets and the installation of the guide rails both have very high requirements for the fixity of the assembly points, that is, it is difficult to fine-tune the position after installation and fixation. This has led to the docking of the guide rails supported by the brackets being difficult to obtain a high guide rail straightness, and it is almost impossible to make corresponding corrections in the later stage of installation. The above situations have led to problems such as high assembly difficulty, low installation accuracy, and poor elevator use experience of the elevator guide rails.

[0004] In summary, the existing elevator car brackets have problems of high assembly difficulty and low accuracy. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is that the existing elevator car brackets have problems of high assembly difficulty and low accuracy.

[0006] To solve the above problems, the utility model provides an adjustable elevator car bracket, which includes a wall fixing member and a guide rail mounting member that are installed and connected to each other. Both the wall fixing member and the guide rail mounting member are in the shape of an L-shaped right-angled bent plate surface structure. The wall fixing member includes a wall fixing plate and a first connecting plate that are integrally formed and perpendicular to each other. The wall fixing plate is used for fixedly connecting with the inner wall of the elevator shaft. The guide rail mounting member includes a guide rail mounting plate and a second connecting plate that are integrally formed and perpendicular to each other. The guide rail mounting plate is used for installing and connecting with the side guide rail of the elevator car. The first connecting plate and the second connecting plate are installed and connected through a threaded connecting member;

[0007] The wall fixing plate is provided with more than one set of symmetrically distributed long hole groups, and each long hole group includes obliquely long mounting holes that are axially symmetric about the middle axis of the wall fixing plate. The length direction of the obliquely long mounting holes forms an angle less than 90° with the length direction of the wall fixing plate.

[0008] This design leaves a margin for translational position adjustment between the wall fixing plate and the inner wall of the elevator shaft through the structure of the obliquely long mounting holes themselves. The docking of the oblique holes can conveniently align with the hole structure for connection and fixation by sliding the wall fixing plate, and accordingly adjust the connection position between the two to change the installation height of the elevator car bracket, making the operation relatively more convenient; and because the oblique long holes are used for connection, when the car side bracket bears the inertial impact from the elevator car during elevator operation, the docking of the oblique holes can ensure the stability of the installation point position of the adjustable elevator car bracket. When a large tensile force is borne at one end of the bracket, it will only make the connection tighter and tighter without deformation or dislocation. In summary, this design of the elevator car bracket effectively solves the problems of high assembly difficulty and low precision existing in the existing elevator car brackets.

[0009] As a preferred solution, the wall fixing plate is provided with two sets of symmetrically distributed long hole groups. Optimizing the hole distribution of the above design, the structural design of two sets of long hole groups on the wall fixing plate can provide more mounting hole positions to adapt to different wall mounting point distribution situations.

[0010] As a preferred solution, more than one set of guide rail hole groups are provided on the guide rail mounting plate, and each guide rail hole group includes two guide rail mounting holes that are symmetrically distributed about the middle axis of the guide rail mounting plate.

[0011] As a preferred solution, two sets of guide rail hole groups are provided on the guide rail mounting plate, and the distances between the respective guide rail mounting holes of the two sets of guide rail hole groups and the middle axis of the guide rail mounting plate are different, which are used to adapt to different guide rails and connector models. This design optimizes the hole structure design on the above guide rail mounting plate. By setting two sets of guide rail hole groups with different hole distances, it can adapt to elevator guide rails with different widths, and accordingly can also adapt to different models of connectors.

[0012] As a preferred solution, the guide rail mounting holes are all in the shape of waist-shaped holes, round holes or long strip holes, which are used to provide a margin for the installation adjustment of the connectors. Optimizing the hole structure of the above guide rail mounting holes, the structure of the waist-shaped holes or long strip holes further increases the adjustment margin of the installation position, reduces the installation difficulty, and is convenient for on-site operation at the construction site; among them, the round hole type is a positioning hole structure, and its position adjustment margin is realized through the hole structure on the connector that cooperates with the guide rail.

[0013] As a preferred solution, raised rib structures are provided at the symmetry axis positions of the wall fixing plate, the first connecting plate, the second connecting plate, and the guide rail mounting plate respectively. After the first connecting plate and the second connecting plate are butted, the raised rib structures of each of them form a hollow columnar structure. This improves the strength of the wall fixing member and the guide rail mounting member, and enhances the impact resistance of the bracket.

[0014] As a preferred solution, flanging reinforcing rib structures perpendicular to their respective plate surfaces are integrally provided at the edges of the wall fixing plate and the first connecting plate, which are used to improve the load-bearing capacity of the wall fixing member. Through this structure, the strength of the wall fixing member is enhanced, especially its bending resistance.

[0015] As a preferred solution, flanging reinforcing rib structures perpendicular to their respective plate surfaces are integrally provided at the edges of the guide rail mounting plate and the second connecting plate, which are used to improve the load-bearing capacity of the guide rail mounting member. Similarly to the above design, through this structure, the strength of the guide rail mounting member is enhanced, especially its bending resistance.

[0016] As a preferred solution, a pair of first connecting long holes that are symmetrical about its axis are provided on the first connecting plate, and the length direction of the first connecting long holes is perpendicular to the axis of the first connecting plate; a pair of second connecting long holes that are symmetrical about its axis are also provided on the second connecting plate, and the length direction of the second connecting long holes is parallel to the axis of the second connecting plate. The first connecting plate and the second connecting plate are installed and connected by inserting threaded connectors into the first connecting long holes and the second connecting long holes. This design optimizes the docking structure design between the first connecting plate and the second connecting plate. By assembling threaded connectors into the symmetrically arranged long holes for fixation, adjustment margins are provided to reduce the assembly difficulty.

[0017] As a preferred solution, more than one group of first connecting long holes are provided on the first connecting plate, and more than one group of second connecting long holes are provided on the second connecting plate, which are used to provide position adjustment margins between the first connecting plate and the second connecting plate.

[0018] As a preferred solution, two or more groups of the first connecting long holes that are parallel to each other and located at different axial positions are provided on the first connecting plate, and two or more groups of the second connecting long holes that are parallel to each other and located at different axial positions are provided on the second connecting plate, which are used to provide position adjustment margins between the first connecting plate and the second connecting plate. On the basis of the above design structure, the installation and docking between the two connecting plates are further carried out, and a group of connecting long holes is added, increasing the distance adjustment space between the elevator guide rail and the elevator shaft wall to adapt to different elevator car models and the shapes of elevator shaft walls.

[0019] As a preferred solution, the first connecting plate is provided with a pair of first obliquely long connecting holes that are symmetrical about its axis, and the inclination direction of the first obliquely long connecting holes is opposite to the inclination direction of the obliquely long mounting holes. The second connecting plate is also provided with a pair of second obliquely long connecting holes that are symmetrical about its axis, and the inclination direction of the second obliquely long connecting holes is opposite to the inclination direction of the first obliquely long connecting holes. The first connecting plate and the second connecting plate are installed and connected by installing threaded connectors in the first obliquely long connecting holes and the second obliquely long connecting holes. This design provides another docking structure design between the first connecting plate and the second connecting plate that is parallel to the above design. Fixed by assembling threaded connectors into the inclined long holes, it can not only provide adjustment margin to reduce the assembly difficulty, but also improve the self-locking performance of the bracket connection under stress conditions.

[0020] As a preferred solution, the first connecting plate is provided with more than one set of first obliquely long connecting holes, and the second connecting plate is provided with more than one set of second obliquely long connecting holes, which are used to provide a position adjustment margin between the first connecting plate and the second connecting plate.

[0021] As a preferred solution, the first connecting plate is provided with more than two sets of first obliquely long connecting holes that are parallel to each other and located at different axial positions, and the second connecting plate is provided with more than two sets of second obliquely long connecting holes that are parallel to each other and located at different axial positions, which are used to provide a position adjustment margin between the first connecting plate and the second connecting plate. On the basis of the above design, by adding connection hole groups, the distance adjustment space between the elevator guide rail and the elevator shaft wall is increased to adapt to different elevator car models and elevator shaft wall shapes.

[0033] Refer to Figure 1 , Figure 2 The following embodiments are described as follows. Figure 1 It is a schematic diagram of an adjustable elevator car bracket structure provided by the present utility model; Figure 2 It is a schematic diagram of a second adjustable elevator car bracket structure provided by the present utility model;

[0034] The present utility model provided in this embodiment provides an adjustable elevator car bracket, which includes a wall fixing member and a guide rail mounting member that are installed and connected to each other. Both the wall fixing member and the guide rail mounting member are in the shape of an L-shaped right-angled bent plate surface structure. The wall fixing member includes a wall fixing plate 1 and a first connecting plate 2 that are integrally formed and perpendicular to each other. The wall fixing plate 1 is used for fixedly connecting with the inner wall of the elevator shaft. The guide rail mounting member includes a guide rail mounting plate 4 and a second connecting plate 3 that are integrally formed and perpendicular to each other. The guide rail mounting plate 4 is used for mounting and connecting with the side guide rail of the elevator car. The first connecting plate 2 and the second connecting plate 3 are installed and connected through a threaded connecting member;

[0035] The wall fixing plate 1 is provided with two symmetrically distributed long hole groups. Each long hole group includes two obliquely long mounting holes 5 that are parallel to each other. The length direction of the obliquely long mounting hole 5 forms an angle less than 90° with the length direction of the wall fixing plate 1.

[0036] This design leaves a margin for mutual translation and position adjustment between the wall fixing plate and the inner wall of the elevator shaft through the structure of the obliquely long mounting hole itself. The docking of the oblique holes can conveniently align the sliding of the wall fixing plate to the hole structure for connection and fixation, and accordingly adjust the connection position between the two to change the installation height of the adjustable elevator car bracket, and the operation is relatively more convenient; and because the oblique long holes are used for connection, when the car side bracket bears the inertial impact from the elevator car during the operation of the elevator, the docking of the oblique holes can ensure the stability of the installation point position of the adjustable elevator car bracket. When one end of the bracket bears a large tensile force, it will only make the connection tighter and tighter, and will not deform or become dislocated. In summary, this design of the adjustable elevator car bracket solves the problems of high assembly difficulty and low precision existing in the existing adjustable elevator car brackets.

[0037] In the technical solution provided in this embodiment, two groups of guide rail hole groups are provided on the guide rail mounting plate 4. Each group of guide rail hole groups includes two guide rail mounting holes 6 that are symmetrically distributed about the central axis of the guide rail mounting plate 4. The distances between the respective guide rail mounting holes 6 of the two groups of guide rail hole groups and the central axis of the guide rail mounting plate 4 are different, and are used to adapt to different guide rails and connector models.

[0038] This design optimizes the hole structure design on the above-mentioned guide rail mounting plate. By setting two groups of guide rail hole groups with different hole distances, it can adapt to elevator guide rails with different widths, and accordingly can also adapt to different types of connectors; on this basis, the number of groups of guide rail mounting holes can also be increased to further improve the adaptability to the connection with the guide rail.

[0039] In the technical solution provided in this embodiment, the guide rail mounting holes 6 are all waist-shaped hole types, round hole types, or long strip hole types, which are used to provide installation adjustment margins for the connecting pieces. This design optimizes the hole structure of the above-mentioned guide rail mounting holes. The waist-shaped hole structure is similar to the above-mentioned connecting long hole, but the ratio of the axial length to the radial width of the hole is smaller than that of the connecting long hole. Therefore, it has better installation and fixation compared to the connecting long hole; the installation position adjustment margin is further increased through the structure of the waist-shaped hole, the installation difficulty is reduced, and it is convenient for on-site operation at the construction site.

[0040] In the technical solution provided in this embodiment, raised rib structures 9 are provided at the symmetry axis positions of the wall surface fixing plate 1, the first connecting plate 2, the second connecting plate 3, and the guide rail mounting plate 4 respectively. After the first connecting plate 2 and the second connecting plate 3 are butted, the raised rib structures 9 of each of them form a hollow columnar structure. The strength of the wall surface fixing piece and the guide rail mounting piece is improved, and the impact resistance of the bracket is enhanced.

[0041] In the technical solution provided in this embodiment, flanging reinforcement structures 10 perpendicular to their respective plate surfaces are integrally provided at the edges of the wall surface fixing plate 1 and the first connecting plate 2, which are used to improve the load-bearing capacity of the wall surface fixing piece. The strength of the workpiece of the wall surface fixing piece is enhanced through this structure, especially its bending resistance.

[0042] In the technical solution provided in this embodiment, flanging reinforcement structures 10 perpendicular to their respective plate surfaces are integrally provided at the edges of the guide rail mounting plate 4 and the second connecting plate 3, which are used to improve the load-bearing capacity of the guide rail mounting piece. By the same token as the above design, the strength of the workpiece of the guide rail mounting piece is enhanced through this structure, especially its bending resistance.

This design optimizes the docking structure design between the first connecting plate and the second connecting plate. It is fixed by installing threaded connecting pieces into the symmetrically arranged long holes, providing an adjustment margin and reducing the assembly difficulty.
