Description

Technical Field

[0001] This utility model belongs to the field of elevator pressure guide plate technology, and in particular relates to a high-strength pressure guide plate assembly. Background Technology

[0002] The elevator guide rail pressure plate is a key component for fixing the guide rail. Its main function is to accurately fix the guide rail to the guide rail bracket of the car or counterweight, ensuring that the guide rail is installed vertically or stably according to the design trajectory.

[0003] Patent CN214569923U discloses a pressure guide plate for elevators. The pressure guide plate is a one-piece molded structure, with the side abutment and the positive pressure part connecting to form a preset angle. This angle is a critical part for stress. When the elevator guide rail is subjected to a large lateral impact force, fatigue damage may occur at the angle due to stress concentration. Especially when the material strength is insufficient, deformation or fracture may occur, reducing the limiting effect.

[0004] Therefore, it is necessary to improve the pressure guide plate assembly in the existing technology. Utility Model Content

[0005] The purpose of this invention is to overcome the defects in the existing technology and provide a high-strength pressure guide plate assembly, which improves the limiting effect of the pressure guide plate assembly on the guide rail.

[0006] To achieve the above objectives, the specific technical solution of the high-strength pressure guide plate assembly of this utility model is as follows:

[0010] Preferably, there are multiple first bolt holes arranged along the first direction, and the number of the waist-shaped holes and the number of bolts are consistent with the number of the first bolt holes and correspond one-to-one.

[0011] Preferably, the clamping member is a square tube structure and extends perpendicular to the first direction. A second cutting part is provided on the front end of the clamping member near the mounting bracket. The second cutting part extends through the clamping member along the first direction. The inner wall of the second cutting part is in contact with both the upper pressing part and the side abutment part.

[0012] Preferably, the front end of the second cutting part is provided with a protrusion, and the protrusion abuts against the side of the upper pressing part that is away from the side abutment.

[0023] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0024] The terms "top surface," "bottom surface," and "underside surface" are used with reference to the normal operating state of the pressure guide plate assembly and are only for the convenience of describing this utility model and simplifying the description. They are not intended to indicate or imply that the device or component 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 utility model.

[0025] like Figure 1-3 As shown, a high-strength pressure guide plate assembly includes a mounting bracket 2 and a pressure guide plate 3. A guide rail 1 is fixedly connected to the mounting bracket 2 via the pressure guide plate 3. A clamping member 4 is provided on the side of the pressure guide plate 3 away from the mounting bracket 2, and both the clamping member 4 and the pressure guide plate 3 are detachably connected to the mounting bracket 2 by bolts 5. The pressure guide plate 3 includes an upper pressing part 301, a side abutting part 302, and a mounting part 303. The upper pressing part 301 abuts against the side of the guide rail 1 away from the mounting bracket 2, the side abutting part 302 abuts against the side of the guide rail 1, and the mounting part 303 is detachably connected to the mounting bracket 2.

[0026] Specifically, the upper pressing part 301, the side abutment part 302, and the mounting part 303 are integrally formed to form a Z-shaped pressure guide plate 3. Two pressure guide plates 3 are fixed to the mounting bracket 2 by bolts 5. The two pressure guide plates 3 are located on both sides of the guide rail 1. The upper pressing part 301 applies pressure to the guide rail 1 towards the mounting bracket 2, pressing and fixing the guide rail 1 to the mounting bracket 2. The side abutment parts 302 of the two pressure guide plates 3 apply force to the sides of the guide rail 1 from both sides to prevent lateral displacement of the guide rail, thereby firmly installing the guide rail 1 on the mounting bracket 2. The clamping part 4 is fixed to the mounting bracket 2 by bolts 5 and fits tightly against the side of the pressure guide plate 3 away from the mounting bracket 2. The clamping part 4 can apply a supporting force to the pressure guide plate 3 to share the force on the pressure guide plate 3, thereby reducing the probability of the pressure guide plate 3 bending or breaking due to force, thereby improving the overall structural strength of the pressure guide plate assembly and improving the firmness of the pressure guide plate assembly in fixing the guide rail 1.

[0027] Further improvements include, for example Figure 2 As shown, the first direction is the extension direction of the guide rail 1. The mounting bracket 2 has waist-shaped holes 201 distributed perpendicular to the first direction. The mounting bracket 2 also has first bolt holes 304. Bolts 5 are sequentially inserted through the waist-shaped holes 201 and the first bolt holes 304.

[0028] In the aforementioned pressure guide plate assembly, the bolt component 5 includes a bolt and a nut. The bolt passes through the first bolt hole 304 and the oblong hole 201 in sequence and is threadedly connected to the nut. After tightening the bolt component 5, the pressure guide plate 3 can be fixedly installed on the mounting bracket 2. The bolt component 5 slides along the extension direction of the oblong hole 201, which can adjust the position of the pressure guide plate 3 so that the pressure guide plate 3 can closely abut against the side of the guide rail 1, improving the firmness of the guide rail 1 installation. Furthermore, the position of the pressure guide plate 3 can be adaptively adjusted for guide rails of different widths, improving the practicality of the pressure guide plate assembly.

[0029] Further improvements include, for example Figure 2 and 3 As shown, multiple first bolt holes 304 are arranged along the first direction, and the number of waist-shaped holes 201 and bolt pieces 5 are consistent with the number of first bolt holes 304 and correspond one-to-one. By using multiple bolt pieces 5 to fix the pressure guide plate 3 simultaneously, the reliability of the pressure guide plate 3 installation can be greatly improved, thereby improving the firmness of the pressure guide plate 3 in fixing the guide rail 1.

[0030] Further improvements include, for example Figure 4 and 5 As shown, the clamping member 4 is a square tube structure and extends perpendicular to the first direction. A second cutting part 403 is provided on the front end of the clamping member 4 near the side of the mounting bracket 2. The second cutting part 403 is provided through the clamping member 4 along the first direction. The inner wall of the second cutting part 403 is in contact with the upper pressing part 301 and the side abutment part 302. A second bolt hole 402 is provided at the end of the clamping member 4 near the side wall of the mounting bracket 2. The bolt 5 is provided through the second bolt hole 402, the first bolt hole 304 and the waist-shaped hole 201 in sequence.

[0031] Specifically, the square tube has a symmetrical rectangular or square cross-section. Compared to a round tube, it has a larger moment of inertia for the same cross-sectional area, which can more evenly distribute external forces. It is especially stable when resisting torsional and bending deformation. Therefore, the square tube structure gives the clamping member 4 higher structural strength. The inner wall of the second cutting part 403 is attached to the surface of the pressing part 301 and the side abutment part 302. The end of the clamping member 4 is close to the side wall of the mounting bracket 2 and is attached to the mounting part 303, so that the clamping member 4 and the pressure guide plate 3 are tightly attached. This makes the clamping member 4 more evenly distribute the force on the pressure guide plate 3 and reduce the probability of deformation of the pressure guide plate 3. When the clamping member 4 is installed, after the second bolt hole 402 on it is aligned with the first bolt hole 304 and the waist-shaped hole 201, the clamping member 4 and the pressure guide plate 3 are fixed to the mounting bracket 2 by the same bolt 5. This can improve the installation firmness while reducing the number of bolts 5, reducing the cost of the pressure guide plate assembly and the convenience of maintenance.

[0032] When the pressure guide plate 3 is fixedly connected to the mounting bracket 2 by multiple bolts 5, the installation position and number of clamping parts 4 can also be selected. In this way, when fixing the light guide rail 1 by the pressure guide plate 3, the number of clamping parts 4 can be reduced, thereby reducing the weight of the pressure guide plate assembly and reducing costs while ensuring the fixing strength of the pressure guide plate 3. When fixing the heavy guide rail 1 by the pressure guide plate 3, the number of clamping parts 4 can be increased to ensure the fixing strength of the pressure guide plate 3. This expands the compatibility range of the pressure guide plate assembly with different models of guide rail 1 and improves its practicality.

[0033] Further improvements include, for example Figure 4 and 5 As shown, the front end of the second cutting part 403 is provided with a protrusion 404, which abuts against the side of the upper pressing part 301 opposite to the side abutment 302. The protrusion 404 and the inner wall of the second cutting part 403 can limit the upper pressing part 301 from both sides, which can first improve the stability of the connection between the pressure guide plate 3 and the clamping member 4, and secondly improve the support effect of the clamping member 4 on the pressure guide plate 3, thereby further improving the structural strength of the pressure guide plate assembly.

[0034] Further improvements include, for example Figure 4 and 5 As shown, a first cutting section 401 is provided on the side of the end of the clamping member 4 away from the mounting bracket 2. The first cutting section 401 is directly opposite the position of the second bolt hole 402. The first cutting section 401 can firstly reduce the weight of the clamping member 4, and secondly provide space for the bolt 5 to enter, which facilitates the installation of the bolt 5, thereby improving the ease of disassembly and assembly of the pressure guide plate assembly.

[0035] Further improvements include, for example Figure 4 and 5 As shown, the clamping member 4 has a hollowed-out portion 405 on its side away from the mounting bracket 2. The hollowed-out portion 405 can reduce the weight of the clamping member 4 and improve the lightweight effect of the pressure guide plate assembly.
