Description

Technical Field

[0001] The invention belongs to the technical field of elevator guide rail installation, and in particular relates to an adaptive guide rail pressing plate and an elevator guide rail assembly. Background Art

[0002] At present, the pressure guide plate of the elevator guide rail is mostly a single sheet metal bending or casting. The shape and structure of the pressure guide plate are relatively fixed and cannot be adjusted according to the change of the guide rail tolerance. The adaptability is relatively poor. For example, CN201921770052.1 is a pressure guide plate for an elevator guide rail. Due to the shape of the existing pressure guide plate design and the design characteristics of the fasteners, it cannot be directly installed and positioned, resulting in a long installation time and the installation quality cannot be guaranteed.

[0003] In addition, the existing pressure guide plate is in direct contact with the wing edge of the guide rail, and the contact is mostly face-to-face, and the guide rail and the guide rail bracket are also in direct face-to-face contact; when building settlement occurs, the guide rail and the guide rail bracket will have a relative movement tendency, thereby causing relative movement between the guide rail and the guide rail bracket, and there is also relative movement between the guide rail and the pressure guide plate. At this time, a large static friction force will be generated between the guide rail and the guide rail bracket and between the guide rail and the pressure guide plate. The generation of this friction force will have a great impact on the design of the pressure guide plate. Summary of the invention

[0035] The present invention will be further described below with reference to the accompanying drawings in specific embodiments;

[0036] This embodiment provides an adaptable guide rail pressure plate, including a pressure guide plate assembly 01, and the pressure guide plate assembly 01 is used for clamping and fixing the wing edge 020 of the guide rail 02; the guide rail 02 is in a "丄" shape, and the pressure guide plate assembly 01 is used for clamping and fixing the wing edge 020 of the guide rail 02;

[0037] The pressure guide plate assembly 01 includes an upper pressure plate 010, a lower pressure plate 011, a first bolt 012 and a second bolt 013;

[0038] The upper pressure plate 010 is strip-shaped. Inside the inner edge of one end of the upper pressure plate 010, a first through hole 0100 is provided. One side of the first through hole 0100 is provided with a second through hole 0101. On the lower surface of the other end edge of the upper pressure plate 010, a first convex block 0102 protrudes; the first convex block 0102 is directly formed by impact protrusion on the upper pressure plate 010. Preferably, the first convex block 0102 is hemispherical to achieve the effect of point contact;

[0039] The present invention changes the form of static friction from the original sliding friction to rolling friction from the friction principle and the convex point design of the upper pressure guide plate, thereby greatly reducing the static friction.

[0040] The lower pressure plate 011 is bent in a Z shape and integrally formed; the lower pressure plate 011 includes a first plate body 0110. The edge of the first plate body 0110 extends and bends to form a second plate body 0111. The edge of the third plate body 0112 extends and bends to form a third plate body 0112. A third through hole 01100 is provided on the first plate body 0110, and a fourth through hole 01120 is provided on the third plate body 0112;

[0041] Preferably, the first plate body 0110 and the third plate body 0112 are arranged in parallel, and the lower pressure plate 011 is bent into a vertical state;

[0042] The upper pressing plate 010 is attached to the first plate body 0110, and the first bolt 012 passes through the first through hole 0100 and the third through hole 01100 and is screwed on the first nut to fix; the upper pressing plate 010 is connected to the lower pressing plate 011 by the first bolt 012, which is convenient for disassembly, assembly and adjustment;

[0043] The wing edge 020 of the guide rail 02 is clamped between the first protrusion 0102 and the third plate body 0112, and there is a distance between the upper pressure plate 010 and the third plate body 0112; the second bolt 013 passes through the second through hole 0101 and the fourth through hole 01120 and is screwed into the anti-loosening nut 03 to fix it, and the upper pressure plate 010 and the third plate body 0112 are tightened by the second bolt 013.

[0044] As described above, in the actual installation process, the guide rail 02 bracket is installed on the wall of the elevator car of the house, and the guide rail 02 is installed on the guide rail 02 bracket; the upper pressing plate 010 and the lower pressing plate 011 are assembled, and are clamped on the wing edge 020 of the guide rail 02 respectively, and the second bolt 013 is passed through the upper pressing plate 010 and the third plate body 0112, and then the anti-loosening nut 03 is screwed on and locked;

[0045] Furthermore, the first through hole 0100 is a waist-shaped hole, and the third through hole 01100 is a round hole.

[0046] As described above, the first through hole 0100 adopts a waist-shaped hole structure, which can adjust the front-to-back distance of the upper pressing plate 010, adapt to guide rails 02 of different sizes, and ensure the installation quality of the guide rails 02;

[0047] Furthermore, the second through hole 0101 is a rectangular hole, and a rectangular block 0120 protrudes from the lower surface of the nut of the second bolt 013 , and the rectangular block 0120 is inserted into the second through hole 0101 to limit rotation.

[0048] As described above, after the anti-loosening nut 03 is screwed onto the second bolt 013, in order to prevent the second bolt 013 from self-rotating and causing loosening, the second through hole 0101 of the upper pressing plate 010 is improved into a rectangular hole, which can ensure that the second bolt 013 can pass through normally, and at the same time, the rectangular block 0120 under the nut of the second bolt 013 is just filled into the second through hole 0101, and the two side surfaces of the rectangular block 0120 are just restricted by the second through hole 0101 and will not rotate anymore;

[0049] Furthermore, it also includes a limiting foot 04; the limiting foot 04 includes a curved U-shaped bar 040, and the lower surfaces of the two ends of the U-shaped bar 040 are respectively protruded with fixing blocks 041; the U-shaped bar 040 and the fixing block 041 are integrally formed for easy use;

[0050] The upper surface of the third plate body 0112 is provided with two fifth through holes 01121;

[0051] The two fixing blocks 041 are embedded in the fifth through hole 01121 and fixed, the lower surface of the U-shaped bar 040 is in contact with the upper surface of the third plate body 0112 , and the middle outer surface of the U-shaped bar 040 is used to be in contact with the wing edge 020 of the guide rail 02 .

[0052] As described above, a limiting foot 04 is added between the upper pressing plate 010 and the lower pressing plate 011, and the limiting foot 04 is embedded and fixed on the lower pressing plate 011; preferably, the upper and lower pressing plates 011 are clamped and fixed; the middle part of the U-shaped bar 040 directly touches the guide rail 02, which has a positioning effect. When in use, it can be directly pressed against the guide rail 02 without calibration;

[0053] Furthermore, the fourth through hole 01120 is a square hole;

[0054] A positioning insert 05 is inserted into the fourth through hole 01120; the positioning insert 05 includes a fourth plate body 050, a sixth through hole 0500 is formed on the fourth plate body 050, two edges of the fourth plate body 050 are bent to form a fifth plate body 051, and communicating notches are formed on both sides of the sixth through hole 0500, and the distance between the two notches matches the thread diameter of the second bolt 013; two fifth plates 051 are inserted into the fourth through hole 01120, and the second bolt 013 passes through the sixth through hole 0500 to remain fixed.

[0055] As mentioned above, in order to further prevent the second bolt 013 from rotating, a positioning insert 05 is added. After the second bolt 013 passes through the upper pressing plate 010 and the lower pressing plate 011, the positioning insert 05 is inserted from the tail of the second bolt 013. The distance between the two notches is equal to the thread diameter of the second bolt 013. However, the diameter of the sixth through hole 0500 is smaller than the nominal diameter of the second bolt 013. Therefore, the positioning insert 05 cannot rotate on the second bolt 013 and can only be pushed up horizontally. The positioning insert 05 is embedded in the fourth through hole 01120 and fixed. The fourth plate body 050 is stuck on the second bolt 013 and cannot rotate.

[0056] Furthermore, a second bump 01122 is protruded from the upper surface of the third plate body 0112 , and the second bump 01122 and the first bump 0102 are arranged in a front-to-back staggered manner.

[0057] As described above, the second protrusion 01122 and the second protrusion 01122 are used to clamp the fixed guide rail 02, so that the contact mode is changed from line-surface contact to point-surface contact, thereby reducing the friction between them; at the same time, the first protrusion 0102 and the second protrusion 01122 are staggered front and back, and when pressure is applied, there is a staggered effect, similar to up and down shearing, and the clamping is tighter;

[0058] Furthermore, two notches 01123 are provided on the outer edge of the third plate 0112;

[0059] It also includes a round shaft 06 , the end of which is inserted into the recess 01123 and fixed therein, and the round shaft 06 is clamped and fixed between two third plates 0112 , and the round shaft 06 is attached to the guide rail 02 .

[0060] As described above, the circular shaft 06 plays a supporting role, changing the static friction mode between the guide rail 02 and the pressure guide plate assembly 01, thereby reducing the static friction force.

[0061] An elevator guide rail 02 assembly with the above-mentioned adaptive guide rail 02 pressure plate includes two parallel guide rails 02, and a pressure guide plate assembly 01 is installed on the wing edge 020 of each guide rail 02; it also includes a mounting plate 07, the mounting plate 07 spans between the two guide rails 02, and the mounting plate 07 is clamped and fixed between the anti-loosening nut 03 and the lower pressure plate 011.

[0062] As mentioned above, the mounting plate 07 is provided with a hole for the second bolt 013 to pass through; the mounting plate 07 serves to support and pull the two guide rails 02;
