Description

Technical Field

[0001] This utility model relates to the field of elevator anchor bolt equipment technology, specifically an elevator fastening anchor bolt with reinforcing ribs. Background Technology

[0002] Elevator fastening anchors securely fix various key elevator components, such as the car, guide rail supports, and machine room equipment, to the building structure. These anchors can resist various forces and vibrations during elevator operation, ensuring the overall stability of the elevator structure. By providing strong tensile and shear force resistance, the fastening anchors ensure that the elevator remains stable under normal operation and emergency conditions, thereby greatly improving elevator safety.

[0003] For example, the utility model patent disclosed in publication number CN204491898U discloses an integrated reinforced anchor bolt. The fastening disc, bolt body, and spherical tip are connected sequentially from top to bottom to form an integrated structure. The bolt body has a nail loading cavity that extends through the fastening disc, and the nail is placed within the loading cavity. Several fastening disc reinforcing ribs are integrally provided on the bottom surface of the fastening disc and surrounding the outer wall of the bolt body. Several bolt body support ribs are integrally provided around the outer wall of the top of the bolt body. This utility model effectively prevents deformation of the fastening disc by providing fastening disc reinforcing ribs. Furthermore, the protruding fastening disc reinforcing ribs are embedded in the insulation board, which can fix the entire anchor bolt and prevent it from rotating and falling off. The bolt body support ribs effectively prevent anchor bolt deformation caused by firing angle deviation. The spherical tip design increases the effective contact area, preventing bursting after nail penetration and bending deformation at the top. It also makes it easier to press the bolt body into the insulation board.

[0004] Although the aforementioned anchor fastening disc has reinforcing ribs for enhanced support, its limiting end is relatively weak. This results in insufficient stability and rigidity of the expansion plate support after the workpiece is limited, which in turn reduces the stability of subsequent limiting. Therefore, there is an urgent need for an elevator fastening anchor with reinforcing ribs to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide an elevator fastening anchor bolt with reinforcing ribs to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an elevator fastening anchor bolt with reinforcing ribs, comprising a support device for support, wherein a support slide shaft for guidance is slidably engaged on the inner end face of the support device.

[0007] A limiting device is rotatably engaged with the upper end face of the support device;

[0008] A threaded guide shaft is fixedly mounted on the upper end face of the supporting slide shaft, and a fixing plate is fixedly mounted on the top of the threaded guide shaft. An expansion head is fixedly mounted at the center of the lower end face of the supporting slide shaft, and a tapered inclined surface is formed on the upper end face of the expansion head.

[0009] Preferably, the support device includes an alignment chuck, a limiting groove is formed at the center of the upper end face of the alignment chuck, and a fixing sleeve is fixedly provided at the center of the lower end face of the alignment chuck. Expansion pads are equidistantly arranged at the lower end face of the fixing sleeve, a reinforcing rib is fixedly provided at the inner end face of the expansion pad, and a guide slope is formed at the bottom of the inner end face of the reinforcing rib.

[0010] Preferably, the limiting device includes an external hexagonal rotating plate, a threaded rotating groove is provided at the center of the inner end face of the external hexagonal rotating plate, and a limiting retaining shaft is provided at the center of the lower end face of the external hexagonal rotating plate.

[0011] Preferably, the external hexagonal rotating plate is adapted to the limiting rotating groove through the limiting retaining shaft and is rotatably engaged with the upper end face of the alignment chuck. The threaded guide shaft is threadedly connected to the external hexagonal rotating plate through the threaded rotating groove. Both the limiting retaining shaft and the limiting rotating groove are T-shaped, which can effectively improve the stability of the subsequent rotation and engagement of the external hexagonal rotating plate inside the alignment chuck.

[0012] Preferably, the inner end face of the fixed sleeve is provided with a fixed groove, and the outer end face of the supporting slide shaft is provided with a guide slider. The supporting slide shaft is adapted to the fixed groove through the guide slider and thus slidably engaged with the inner end face of the fixed sleeve. The sliding limit of the fixed groove and the guide slider can effectively improve the stability of the subsequent displacement of the supporting slide shaft inside the supporting device.

[0013] Preferably, the expansion head is adapted to the guide slope through the tapered inclined surface and then slidably connected to the reinforcing rib. The adaptation of the tapered inclined surface to the guide slope can effectively improve the stability and convenience of subsequent folding and limiting of the expansion pad.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. By setting multiple sets of guide ramps and reinforcing ribs, this utility model can quickly and stably guide the expansion head when limiting the elevator workpiece. This allows the multiple sets of expansion pads and reinforcing ribs to be quickly and stably folded under the compression and guidance of the guide ramps and expansion head. At the same time, the expansion pads with reinforcing ribs have good support stability after folding, which can maximize the stability of limiting the elevator workpiece. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 One embodiment of this utility model provides an elevator fastening anchor bolt with reinforcing ribs, including a support device 2 for support, and a support slide shaft 6 for guidance slidably engaged with the inner end face of the support device 2.

[0024] Limiting device 3 is rotatably engaged with the upper end face of support device 2;

[0025] A threaded guide shaft 5 is fixedly mounted on the upper end face of the support slide shaft 6, and a fixing plate 4 is fixedly mounted on the top of the threaded guide shaft 5. An expansion head 1 is fixedly mounted at the center of the lower end face of the support slide shaft 6, and a tapered inclined surface 7 is provided on the upper end face of the expansion head 1.

[0026] The support device 2 includes an alignment chuck 24. A limiting groove 23 is formed at the center of the upper end face of the alignment chuck 24, and a fixing sleeve 25 is fixedly provided at the center of the lower end face of the alignment chuck 24. Expansion pads 21 are equidistantly arranged at the lower end face of the fixing sleeve 25. A reinforcing rib 22 is fixedly provided at the inner end face of the expansion pad 21, and a guide slope 26 is formed at the bottom of the inner end face of the reinforcing rib 22.

[0027] The limiting device 3 includes an external hexagonal rotating plate 33, a threaded rotating groove 31 is provided at the center of the inner end face of the external hexagonal rotating plate 33, and a limiting retaining shaft 32 is provided at the center of the lower end face of the external hexagonal rotating plate 33.

[0028] The external hexagonal rotating plate 33 is adapted to the limiting rotating groove 23 through the limiting retaining shaft 32 and is rotatably locked onto the upper end face of the alignment chuck 24. The threaded guide shaft 5 is threadedly connected to the external hexagonal rotating plate 33 through the threaded rotating groove 31. Both the limiting retaining shaft 32 and the limiting rotating groove 23 are T-shaped, which can effectively improve the stability of the external hexagonal rotating plate 33 rotating and locking inside the alignment chuck 24.

[0029] The inner end face of the fixed sleeve 25 is provided with a fixed slide groove, and the outer end face of the support slide shaft 6 is provided with a guide slider. The support slide shaft 6 is slidably engaged with the inner end face of the fixed sleeve 25 by means of the guide slider and the fixed slide groove. The sliding limit of the fixed slide groove and the guide slider can effectively improve the stability of the subsequent displacement of the support slide shaft 6 inside the support device 2.

[0030] The expansion head 1 is adapted to the guide slope 26 through the tapered slope 7 and then slidably connected to the reinforcing rib 22. The tapered slope 7 and the guide slope 26 are adapted to each other, which can effectively improve the stability and convenience of the subsequent folding and limiting of the expansion pad 21.

[0031] Working principle: Before use, the operator can position the workpiece to be installed at the elevator mounting hole. Then, the expansion head 1 and the support device 2 are simultaneously passed through the mounting hole until the alignment chuck 24 is positioned to the required installation area. Then, the operator can limit the external tool to the outside of the hexagonal rotating plate 33 and rotate it. At this time, the hexagonal rotating plate 33 can be threadedly connected to the threaded guide shaft 5 through the threaded groove 31, thereby driving the support sliding shaft 6 and the tapered inclined surface 7 to move vertically upward at the bottom of the fixed sleeve 25. At this time, the support sliding shaft 6 can simultaneously move multiple sets of expansion pads 21 outward through the guide inclined surface 26, so that multiple sets of expansion pads 21 and the guide inclined surface 26 can be folded, thereby limiting the mounting hole in all directions. The expansion pads 21 with reinforcing ribs 22 can effectively improve the overall stability of the anchor bolt limit.
