Description

Technical Field

[0001] The utility model belongs to the technical field of elevators, and in particular relates to a guiding device of an elevator. Background Art

[0002] The stable operation of an elevator is inseparable from the elevator's guiding device. The guiding device specifically refers to the guiding shoe installed on the outside of the elevator car. The guiding shoe can guide the elevator car to stably rise and fall along the guide rail on the inner wall of the passage. For example, the existing patent with publication number CN104520224B discloses "an elevator guiding device, comprising: a guide shoe, which slides on the guide rail; a guide shoe holder, which receives the guide shoe and is installed on the lifting body". It can be seen that the application describes a common elevator guiding device;

[0003] In the actual use of the elevator guide device in the prior art, the guide shoe body is generally fixed directly to the inner side of the retaining frame by bolts. Since no auxiliary positioning structure is designed between the two, the guide shoe body cannot be quickly positioned during installation. At the same time, when the guide shoe body is disassembled and replaced, the removal of the fixing bolts may directly cause the guide shoe body to slip, which is inconvenient. Therefore, the utility model proposes an elevator guide device. Utility Model Content

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0018] See also Figures 1 to 3 , which is the first embodiment of the utility model, and the embodiment provides a technical solution: a guide device of an elevator, comprising a fixed base plate 1, a retaining frame 2, a guide shoe body 3 and a fixing bolt 6, the fixed base plate 1 is fixed to the surface of the elevator car 4 by a plurality of bolts, the retaining frame 2 is welded and fixed to the surface of the fixed base plate 1, the guide shoe body 3 is installed on the inner side of the retaining frame 2, and strip sliders 31 are welded and fixed to both side surfaces of the guide shoe body 3, and strip guide grooves 21 are provided on both side inner walls of the retaining frame 2, and the strip sliders 31 slide into the strip guide grooves 21, and side grooves 22 are provided on both side surfaces of the retaining frame 2, and bolt grooves 32 corresponding to the side grooves 22 are provided on both side surfaces of the guide shoe body 3, and the fixing bolts 6 are inserted into the side grooves 22, and the threaded ends of the fixing bolts 6 penetrate and are screwed into the bolt grooves 32, and a positioning structure is provided between the guide shoe body 3 and the retaining frame 2;

[0019] The positioning structure includes an inner groove 71, a spring 72, a telescopic positioning block 73 and a positioning card slot 74. The inner groove 71 is arranged inside the guide shoe body 3. The telescopic positioning block 73 is movably installed in the inner groove 71 through the spring 72. The inner surface of the retaining frame 2 is provided with a positioning card slot 74 corresponding to the telescopic positioning block 73. The end of the telescopic positioning block 73 is embedded in the positioning card slot 74, and the guide shoe body 3 can be engaged and positioned. When the guide shoe body 3 is installed, the guide shoe body 3 is first slid into the inner side of the retaining frame 2, so that the strip slider 31 slides into the strip guide groove 21. During the sliding process, the end of the telescopic positioning block 73 will be squeezed into the inner side of the inner groove 71 by the retaining frame 2 first. When the guide shoe body 3 slides to the bolt groove 32 and the bolt groove 32 is aligned with the bolt groove 32, the guide shoe body 3 is locked. When the side grooves 22 are aligned, the ends of the telescopic positioning block 73 will be inserted into the positioning slots 74 under the push of the springs 72, thereby realizing auxiliary positioning of the guide shoe body 3, thereby completing the rapid alignment of the side grooves 22 and the bolt slots 32 when the guide shoe body 3 is installed. At this time, the guide shoe body 3 and the retaining frame 2 can be fixed by the fixing bolts 6. The positioning structure can play an effective auxiliary positioning role during the installation process. When the guide shoe body 3 is to be removed and replaced later, the fixing bolts 6 will be rotated and unscrewed first. Under the positioning action of the telescopic positioning block 73, even if the fixing bolts 6 on both sides are unscrewed, the guide shoe body 3 will still not slide directly from the inner side of the retaining frame 2, thereby preventing unnecessary falling off during the disassembly and assembly process.

[0020] A threaded hole corresponding to the fixing bolt 6 is formed through the inner wall of the side groove 22 , so that the threaded end of the fixing bolt 6 can be smoothly screwed into the inner side of the bolt groove 32 .

[0021] One end of the spring 72 is fixed to the inner wall of the inner groove 71 , and the other end of the spring 72 is fixedly connected to the telescopic positioning block 73 , thereby ensuring the installation stability of the spring 72 and the telescopic positioning block 73 .

[0022] Among them, it also includes a blocking protection structure 5, and a blocking protection structure 5 is set on both sides of the retaining frame 2. The blocking protection structure 5 includes a rectangular slide groove 51 opened inside the retaining frame 2, and a rectangular slider 52 is slidably set in the rectangular slide groove 51. A telescopic positioning block 73 is welded and fixed on the front surface of the rectangular slider 52. The telescopic positioning block 73 penetrates to the inner side of the side groove 22 to cover the fixing bolt 6, which can effectively cover and protect the fixing bolt 6 to prevent the fixing bolt 6 from being corroded by foreign objects. When the fixing bolt 6 needs to be removed later, it only needs to push the guard plate 53 to expose the fixing bolt 6.

[0023] A through hole 54 is formed between the rectangular slide groove 51 and the side groove 22 , and the through hole 54 is matched with the guard plate 53 to allow the guard plate 53 to pass through smoothly. Example

[0024] See also Figures 1 to 4, which is the second embodiment of the utility model, is based on the previous embodiment, and the difference is that the guard plate 53 can be limited by the rubber insert 55 and the limiting protrusion 56 and other structures.

[0025] Specifically, a rubber pad 55 is embedded in the inner wall of one side of the through hole 54, and a limiting protrusion 56 is arranged on the surface of the rubber pad 55. A rectangular slot 57 corresponding to the limiting protrusion 56 is opened on the side of the guard plate 53, and the end of the limiting protrusion 56 is embedded in the rectangular slot 57, so that the guard plate 53 can be limited by the limiting protrusion 56 during daily use to ensure that the fixing bolt 6 is continuously covered and protected. At the same time, the subsequent operator only needs to push the guard plate 53 with force to squeeze and deform the limiting protrusion 56 to achieve smooth sliding of the guard plate 53, which will not affect the normal sliding displacement of the guard plate 53. The rubber pad 55 and the limiting protrusion 56 are an integrated structure, and both are made of rubber material. The limiting protrusion 56 is semicircular when viewed from above, so that the limiting protrusion 56 is easy to elastically deform when squeezed by the guard plate 53.

[0026] Although the embodiments of the present invention have been shown and described (see the detailed description above for details), it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
