Description

Technical Field

[0001] This utility model relates to the technology of vertical elevator components, and in particular to an adjustable high-strength counterweight guide rail bracket. Background Technology

[0002] As a support component for the guide rail, the vertical elevator guide rail bracket not only fixes the spatial position of the guide rail but also bears various forces from the guide rail. Its structural stability is of great significance to the normal operation of the elevator. Due to the limitations of shaft space and the diversity of actual working conditions, bracket components with reasonable layout, adjustable space and sufficient connection strength are required.

[0003] Generally, when designing counterweight guide rail support structures, a larger plate thickness is required to improve the strength of the lower support. The upper support is a cantilever structure, and in order to overcome the impact of the increased distance between the center of the counterweight guide rail and the wall on the strength, profiles with a larger section modulus need to be selected. Therefore, the amount of material used for both the upper and lower supports is large, resulting in heavy weight and high cost. On the other hand, due to the small contact area between the upper and lower supports, the installation requirements are very high in order to ensure the connection strength between the upper and lower supports. Summary of the Invention

[0004] The purpose of this utility model is to solve the above problems and provide an adjustable high-strength counterweight guide rail bracket. It has multi-angle adjustment capability, increases structural strength without increasing plate thickness, ensures and strengthens the connection strength between the upper and lower brackets, and facilitates on-site assembly.

[0005] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: an adjustable high-strength counterweight guide rail bracket, including an upper bracket and a lower bracket, characterized in that the upper bracket has a gradually changing cross-sectional modulus structure, including two mutually perpendicular surfaces, wherein the vertical surface is provided with holes that cooperate with the guide rail, and its horizontal surface is a trapezoidal structure, the width of the large base of the trapezoidal structure is equal to the width of the lower bracket, and the part of the horizontal surface near the large base of the trapezoid is connected to the lower bracket by bolts; the lower bracket also has two perpendicular surfaces, and the width of the lower bracket is provided with inward folded ribs on both sides.

[0006] In the aforementioned adjustable high-strength counterweight guide rail bracket, preferably, the holes for bolt connection between the upper bracket and the lower bracket are distributed on two straight lines parallel to the guide rail mounting surface.

[0007] In the aforementioned adjustable high-strength counterweight guide rail bracket, preferably, the holes connecting the upper bracket and the lower bracket are two types of elongated holes arranged perpendicularly to each other.

[0008] In the aforementioned adjustable high-strength counterweight guide rail bracket, preferably, the upper bracket has guide rail positioning holes on its upright side that cooperate with the guide rail, and the guide rail positioning holes are two elongated holes arranged at an angle to each other.

[0009] In the aforementioned adjustable high-strength counterweight guide rail bracket, preferably, the upper bracket has a rectangular plane on its upper side, and its top edge is provided with a flanged reinforcing rib arranged perpendicularly to the guide rail mounting surface.

[0010] In the aforementioned adjustable high-strength counterweight guide rail bracket, preferably, the mating surfaces of the lower bracket and the upper bracket are provided with double rows of holes, which are two rows of parallel elongated holes.

[0011] In the aforementioned adjustable high-strength counterweight guide rail bracket, preferably, the lower bracket has a vertical adjustment hole on another vertical surface opposite to the mating surface of the upper bracket. The vertical adjustment hole is two elongated holes arranged perpendicularly to each other, and the center of the two elongated holes is equidistant from the bend edge of the lower bracket.

[0012] This technical solution achieves the fixed and installed orientation of vertically arranged guide rails through the cooperation of upper and lower supports. The horizontal plane of the two mutually perpendicular planes of the upper support has a trapezoidal structure, which, together with the rectangular facade, gives the upper support a gradually changing cross-sectional modulus structure under a limited volume. It achieves a smooth transition of mechanical properties by gradually changing the modulus (stiffness) distribution at the material interface. In the interface region of the upper support, the elastic modulus or shear modulus of the material gradually transitions from one property to another, avoiding sudden changes, thereby reducing stress concentration, dispersing the stress at the interface, and avoiding failure caused by local high stress.

[0013] The upper support's trapezoidal structure has a base width equal to that of the lower support, meeting on-site installation requirements and providing ample installation space. The lower support also has two vertical surfaces, with inward-folded ribs on both sides of its width, significantly increasing its strength without increasing the plate thickness.

[0014] In this device, all connection holes for the upper and lower supports, as well as for other connecting components and parts, including the concrete ring beam in the shaft, are designed with elongated holes that allow for the required directional adjustment. This ensures a high-precision installation position and guarantees the installation accuracy of the counterweight guide rail.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the design of the cross-sectional modulus gradually changing structure not only provides a more identifiable and effective installation space, but also avoids local high stress concentration in the upper bracket and extends the service life of the components; the design of the flanged reinforcing ribs greatly increases the structural strength of the bracket on the basis of the same thickness, and can also reduce the thickness of the plate, reduce the weight of the accessories, and save costs; the design of the fully adjustable connection holes can meet the adjustment of the components under various complex working conditions on site and ensure the installation accuracy of the elevator body.

[0022] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0023] This embodiment describes an adjustable high-strength counterweight guide rail bracket, mainly composed of an upper bracket 1 and a lower bracket 2, as follows: Figure 1 , Figure 2 As shown.

[0024] The upper support 1 is designed with a gradually changing cross-sectional modulus structure, including two mutually perpendicular surfaces. The upper surface has holes for mating with the guide rail 3, namely guide rail positioning holes 102. Figure 3 As shown, its horizontal plane has a trapezoidal or triangular structure. The width of the large base of the trapezoidal structure is equal to the width of the lower support 2. A horizontal positioning hole 103 is provided near the large base of the trapezoid on the horizontal plane. The upper support 1 is connected to the lower support 2 through the horizontal positioning hole 103 and the bolt that mates with it.

[0025] The lower support 2 also has two vertical surfaces, forming an equal-width but unequal-sided angle steel structure, such as... Figure 4 As shown, the lower support 2 has inwardly folded ribs 201 on both sides of its width, and the height of the inwardly folded ribs 201 is generally 5-15mm. The holes on the mating surface of the lower support 2 and the upper support 1 are two rows of parallel elongated holes, i.e., double-row group holes 202, with 4 holes in each row. Correspondingly, the two horizontal holes 103 in the upper support 1 are not equidistant from the large base of the trapezoid. The difference in distance between the two holes and the large base of the trapezoid is equal to the distance between two adjacent holes in each row of 4 holes in the double-row group holes 202, forming a staggered connection between the two bolts.

[0026] Furthermore, the holes for bolt connection between the upper bracket 1 and the lower bracket 2 are distributed on two straight lines parallel to the mounting surface of the guide rail 3, namely, the two horizontal holes 103 and the double-row group holes 202 correspond to each other and are parallel to the bottom surface of the guide rail 3; and the holes for connecting the upper bracket 1 and the lower bracket 2 are two kinds of elongated holes arranged perpendicularly to each other, namely, the elongated holes of the horizontal holes 103 and the double-row group holes 202 are arranged perpendicularly to each other.

[0027] The other connection holes on the upper bracket 1 and the lower bracket 2 are configured as follows:

[0028] The upper support 1 has two elongated holes, namely guide rail positioning holes 102, arranged at an angle to each other, on its vertical side to mate with the guide rail 3. The lower support 2 has two elongated holes, namely vertical adjustment holes 203, arranged perpendicularly to each other on its other vertical surface opposite to the mating surface of the upper support 1. The center of the two vertical adjustment holes 203 is equidistant from the bend edge of the lower support. The lower support 2 is fixed to the concrete ring beam or other auxiliary beam in the shaft through the vertical adjustment holes 203.

[0029] In addition, the top edge of the rectangular plane of the upper bracket 1 is provided with a flanged reinforcing rib 101 arranged perpendicular to the mounting surface of the guide rail 3. The height of the flanged reinforcing rib 101 is generally 5-15mm.

[0030] Working principle and usage:

[0031] The gradual change in cross-sectional modulus of the upper support 1 allows for a smooth transition in its mechanical properties. At the interface region of the upper support 1, it avoids stress concentration caused by abrupt changes in the elastic modulus or shear modulus due to forces from the guide rails and other sources, thus dispersing the stress at the interface. Further, a flanged reinforcing rib 101 can be fabricated on the top edge of its facade to expand the strain capacity of the gradually changing cross-sectional modulus structure.

[0032] The addition of inner folded ribs 201 on both sides of the width of the lower support 2 greatly improves its structural strength.

[0033] The guide rail 3 is positioned and fixed to the upper bracket 1 by the clamping plate 4 through the guide rail positioning hole 102, and the horizontal position of the guide rail 3 is adjustable. The upper bracket 1 is connected and fixed to the lower bracket 2 through the horizontal positioning hole 103, the double row group hole 202 and bolts, and the position between the upper bracket 1 and the lower bracket 2 is adjustable. The lower bracket 2 is positioned and fixed to the concrete ring beam in the shaft through the vertical adjustment hole 203, and its vertical and horizontal positions are also adjustable.

[0034] The above embodiments are illustrative of the present invention and not intended to limit it. The described embodiments are merely some, not all, of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art through inspiration from the present invention without creative effort are within the scope of protection of the present invention.
