Description

Technical Field

[0001] The utility model relates to elevator component technology, in particular to a high-strength guide rail connector for an elevator. Background Art

[0002] As a vertical transportation device, the guide rails of elevators play the role of limiting and guiding. The standard length of the guide rails is 5m / piece. In order to meet the requirements of the elevator lifting height, multiple guide rails need to be connected to form a whole. The guide rails need to be connected with connectors. At present, the guide rail connectors are mainly flat plates or plates with folded edges on both sides. During installation, multiple wrenches and other tools are required to tighten them.

[0003] For flat elevator guide rail connectors, if the strength of the connecting plate is to be strong enough, the thickness of the plate needs to be larger, generally more than 10mm, the material consumption of the connecting plate is large, the weight is heavy, and the cost is high. For double-sided flanged elevator guide rail connectors, in order to make the connecting plate strong enough, the flange size on both sides is required to be larger or the plate thickness is required to be 5mm or more, the material consumption of the connecting plate is also large, the weight is heavy, and the cost is high. Summary of the invention

[0004] The purpose of the utility model is to solve the above problems and provide a high-strength guide rail connector for elevators, which has the characteristics of simple processing technology, light weight of thin material molding, high structural strength, low comprehensive cost, easy installation and low error rate.

[0005] The above technical problems of the utility model are mainly solved by the following technical solutions: a high-strength guide rail connector for elevators, characterized in that it includes a first connector and a second connector, the first connector and the second connector are connected by an intermediate rib, the intermediate rib includes a first side surface perpendicular to the first connector, a second side surface perpendicular to the second connector, and the top surface between the first side surface and the second side surface is a plane or an arc surface; the first connector and the second connector are provided with penetrating bolt holes; a first longitudinal bending portion and a second longitudinal bending portion are respectively bent and extended on both sides of the first connector and the second connector.

[0006] In the aforementioned high-strength guide rail connector for elevators, preferably, the distance between the bolt holes provided on the first connector and the second connector and the first side surface and the second side surface is between the selected standard nut outer dimensions s and e.

[0007] In the aforementioned high-strength guide rail connector for an elevator, preferably, when the nut is installed, the edge of the nut is close to the first side surface or the second side surface of the middle rib.

[0008] In the aforementioned high-strength guide rail connector for elevators, preferably, the first connector and the second connector are located in the same plane, and the top surface between the first side surface and the second side surface is a plane, which is parallel to the first connector and the second connector.

[0009] In the aforementioned high-strength guide rail connector for an elevator, preferably, the bending directions of the first longitudinal bending portion and the second longitudinal bending portion are parallel to the first side surface and the second side surface of the middle rib.

[0010] In the aforementioned high-strength guide rail connector for an elevator, preferably, the first longitudinal bent portion and the second longitudinal bent portion have the same bending direction and extend in a direction away from the middle rib.

[0011] In the aforementioned high-strength guide rail connector for elevators, preferably, the first longitudinal bent portion and the second longitudinal bent portion have the same bending direction and extend in the direction of the middle rib.

[0012] In the aforementioned high-strength guide rail connector for an elevator, preferably, the first longitudinal bending portion and the second longitudinal bending portion have opposite bending directions.

[0013] In the aforementioned high-strength guide rail connector for elevators, preferably, the first connector, the second connector, the middle rib, the first longitudinal bending portion and the second longitudinal bending portion are an integrated structure pressed from a plate with a thickness of 2 to 5 mm.

[0014] In the aforementioned high-strength guide rail connector for elevators, preferably, the first connector and the first side surface, the first longitudinal bending portion, the second connector and the second side surface, the second longitudinal bending portion, and the first side surface, the second side surface and the top surface are all connected by arc-shaped transitions.

[0015] This technical solution can be processed by simple processes such as plate stamping or bending. Its basic structure includes a first connector and a second connector located in the same plane, with an intermediate rib designed between the two. Bolt holes for connecting to the guide rail are provided on the first connector and the second connector. Based on this, a first longitudinal bending portion and a second longitudinal bending portion are bent and extended on both sides of the first connector and the second connector.

[0016] The first longitudinal bend and the second longitudinal bend are two relatively flexible folds, which can be set according to different positioning requirements of the guide rail. However, no matter which extension bend is adopted, the structural strength of the component can be greatly improved. Therefore, thin plates can be used to reduce the weight and cost of the material, and residual thermal stress caused by hot processing can be prevented. The setting of the middle rib of the device can fully guarantee the high strength and life of the connecting piece. Due to the existence of the middle rib, the elevator guide rail connecting plate only reserves one connection surface connected to the elevator guide rail, thereby reducing the installation error rate. At the same time, since only the processing accuracy and flatness of one connection surface need to be guaranteed, the processing difficulty and cost are also reduced.

[0017] In the molding details of this device, the bolt hole meets the requirements of the standard nut outer dimensions s and e, and also provides a reference surface for the nut installation side to prevent the nut from rotating during installation, so that the operation can be completed with a single wrench. The bending surfaces are continuous with each other in parallel and vertical directions, which is conducive to mold removal during molding. The extension and bending of the first longitudinal bending part and the second longitudinal bending part in different directions not only make the product form a component with relatively ideal structural strength, but also do not increase the complexity of the components and the difficulty of installation and identification.

[0018] Compared with the prior art, the beneficial effects of the utility model are: the product can be obtained through simple processing techniques such as sheet metal stamping, the strength of the component is increased, the thickness of the plate is reduced to reduce the weight of the finished product, the material cost and processing cost are reduced, the residual thermal stress caused by hot processing is prevented, the installation error rate is reduced, the distance between the bolt hole and the side of the middle rib is limited, the nut is self-limited, the installation is convenient, and the installation work intensity is reduced.

[0032] The technical solution of the utility model is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0033] This embodiment is a high-strength guide rail connector 1 for an elevator, such as Figure 1 , Figure 2 As shown, it includes a first connector 101 and a second connector 102 located in the same plane, and the first connector 101 and the second connector 102 are connected by a middle rib. The middle rib includes a first side surface 103 perpendicular to the first connector 101, a second side surface 104 perpendicular to the second connector 102, and a top surface 107 between the first side surface 103 and the second side surface 104 is a plane or an arc surface. A first longitudinal bending portion 105 and a second longitudinal bending portion 106 are bent and extended on both sides of the first connector 101 and the second connector 102, respectively.

[0034] The first connector 101 and the second connector 102 are located in the same plane, and the top surface 107 between the first side surface 103 and the second side surface 104 is a plane, which is parallel to the first connector 101 and the second connector 102. When the top surface 107 is an arc surface, it can be symmetrical in the center.

[0035] The first connector 101 and the second connector 102 are provided with bolt holes 108 arranged symmetrically with the middle rib and penetrating therethrough, i.e., the guide rail connecting plate holes. The width of the guide rail connector 1 matches the width of the installation bottom surface of the guide rail 2, and the length of the guide rail connector 1 is based on the two docking guide rails 2 each having 2*2 sets of fasteners 3, and the fasteners 3 include bolts, nuts, flat washers, spring washers, etc. The distance between the bolt holes 108 provided on the first connector 101 and the second connector 102 and the first side surface 103 and the second side surface 104 should be between the selected standard nut outer dimensions s and e, so that when the nut is installed, the edge of the nut is close to the first side surface 103 or the second side surface 104 of the middle rib, so that the nut is limited.

[0036] In this embodiment, the first connector 101, the second connector 102, the middle rib, the first longitudinal bending portion 105 and the second longitudinal bending portion 106 are an integrated structure formed by pressing a plate material with a thickness of 2 to 5 mm. The first connector 101 and the first side surface 103 and the first longitudinal bending portion 105, the second connector 102 and the second side surface 104 and the second longitudinal bending portion 106, and the first side surface 103, the second side surface 104 and the top surface 107 are all connected by arc transitions.

[0037] Example 1: See also Figure 1 , Figure 2 The bending directions of the first longitudinal bending portion 105 and the second longitudinal bending portion 106 are parallel to and in the same direction as the first side surface 103 and the second side surface 104 of the middle convex rib, that is, they extend in a direction away from the middle convex rib.

[0038] During installation, the guide rail connector 1 is installed between the docking rail A201 and the docking rail B202, and is placed on the bottom surface of the docking rail A201 and the docking rail B202. Since the spacing between the first longitudinal bending portion 105 and the second longitudinal bending portion 106 matches the bottom width of the guide rail 2, positioning is easy. Figures 3 to 5 As shown, as long as the bolt hole 108 is aligned with the mounting hole at the end of the guide rail 2, the fastener 3 can be put in place. Since the nut is in close contact with one of the two side portions of the middle rib, the fastener 3 can be tightened with a single wrench.

[0039] Example 2: See Figure 6 , Figure 7 This example is defined as a longitudinally folded same-direction M-shaped connector 1a, the bending directions of the first longitudinal bending portion 105 and the second longitudinal bending portion 106 are parallel to the first side surface 103 and the second side surface 104 of the middle rib, the bending directions are the same, and extend toward the direction of the middle rib.

[0040] During installation, if Figure 8As shown, it is carried out between docking rail A201 and docking rail B202, and the guide rail connector 1 is placed on the bottom surface of docking rail A201 and docking rail B202. Since it is a symmetrical structure product, the deformation structure of the middle rib and the first longitudinal bend 105 and the second longitudinal bend 106 can fully guarantee the strength and service life required for the connection, and the guide rail connector 1 has only two contact surfaces connected to the elevator guide rails, only the front and back sides are required, and there is no distinction in the length direction. It is easy to distinguish the installation position, thereby reducing installation errors. For the product of this embodiment, since only the processing accuracy and flatness of the connection surface need to be guaranteed, the processing difficulty and cost are reduced. Since the nut is in close contact with one of the two sides of the middle rib, the fastener 3 can be tightened with a single wrench.

[0041] Example 3: See Fig. 9 , Fig.10 This example is defined as a longitudinal folding reverse type connector 1b, and the other structures are the same as the common features mentioned above, and the bending directions of the first longitudinal bending portion 105 and the second longitudinal bending portion 106 are opposite.

[0042] During installation, if Fig.11 As shown, the guide rail connector 1 is placed between the docking rail A201 and the docking rail B202. Although it is not a symmetrical structure, the deformation structure of the middle rib, the first longitudinal bend 105, and the second longitudinal bend 106 can fully guarantee the strength and service life required for the connection. The guide rail connector 1 is mainly two contact surfaces connected to the elevator guide rails. The additional first longitudinal bend 105 fits tightly with the guide rail 2, which is also easy to determine the installation position and reduce installation errors. Since the nut is in close contact with one of the two sides of the middle rib, the fastener 3 can be tightened with a single wrench.

[0043] The above embodiments are illustrations of the present invention, not limitations of the present invention. Without departing from the principles of the present technical solution, any equivalent changes or equivalent modifications made in accordance with the technical ideas proposed by the present invention shall still fall within the scope of protection of the technical solution of the present invention.
