Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a straight beam for a small hoistway elevator. Background Art

[0002] A sightseeing elevator is an elevator for passengers to enjoy the scenery outside the cabin. It is common in scenic spots or high-rise buildings.

[0003] Observation elevators are generally installed in small shafts, so the overall volume they occupy is also small.

[0004] The straight beam is an important component of the sightseeing elevator, but the straight beam of the prior art is relatively large as a whole, and components such as guide shoes and safety clamps are installed on both sides of the straight beam. This structure is not suitable for installation in a small hoistway. Utility Model Content

[0005] The technical solution to be solved by the utility model is to provide a small hoistway elevator straight beam which occupies a small space.

[0006] The technical solution adopted by the utility model is: a straight beam of a small hoistway elevator, which includes an A surface, a B surface integrally bent and formed on both sides of the A surface and perpendicular to the A surface, and a C surface integrally bent and formed on a side of the B surface away from the A surface and perpendicular to the B surface, a wire groove is formed among the A surface, the B surface and the C surface, and the A surface is provided with an upper beam mounting hole, a first guide shoe mounting hole, a first safety clamp mounting hole, a hollow hole, a second safety clamp mounting hole, a second guide shoe mounting hole and a lower beam mounting hole in sequence from top to bottom.

[0007] Preferably, a process hole is also provided on the A surface.

[0008] Preferably, there are two process holes, and the two process holes are arranged between the second safety clamp mounting hole and the hollow hole.

[0009] Preferably, cable holes are provided on both sides between the upper beam mounting hole and the first guide shoe mounting hole, and the cable holes (13) are connected to the wire trough.

[0010] Preferably, the first safety clamp mounting hole and the second safety clamp mounting hole are inclined waist-shaped mounting holes.

[0011] Preferably, the first guide shoe mounting hole and the second guide shoe mounting hole both include an insertion hole for the guide shoe to be inserted into, an insertion groove for the guide shoe to be moved downward and inserted into, and a locking hole for a locking member to pass through and lock the guide shoe.

[0012] Compared with the prior art, the utility model has the following advantages: the mounting holes are arranged on the A side and in a vertical row, so that all components can be installed on the straight beam and the straight beam can be made very small, so that the overall space occupied by the straight beam is small, and the two sides of the straight beam are bent to form cable grooves for cables to pass through.

[0013] Setting process holes on the A surface can save some materials and reduce some costs.

[0014] Cable holes are set on the straight beams so that the cables can pass through the cable trough and then out of the cable holes, making the connection more convenient.

[0015] The first safety clamp mounting hole and the second safety clamp mounting hole are made into inclined waist-shaped holes. In this way, under normal conditions, the safety clamp is at the bottom of the waist-shaped hole under the action of gravity. At this time, the moving side and the fixed side of the safety clamp are not in contact with the guide rail, and the elevator works normally. When the safety clamp is triggered, the roller on the moving side of the safety clamp moves, so that the moving side contacts the guide rail. Because the safety clamp is installed in the waist-shaped mounting hole, the safety clamp can move in the waist-shaped mounting hole at this time, so that the fixed side of the safety clamp also contacts the guide rail. In this way, both sides of the guide rail are in contact with the safety clamp, the guide rail is evenly stressed, the braking effect is better, and the center of the guide rail and the guide shoe remains unchanged, so that the guide rail is not easily damaged.

[0016] The guide shoe mounting hole is arranged in this way, so that the guide shoe can be inserted into the insertion hole and then embedded into the embedding groove and finally locked by the locking piece passing through the locking hole, which is convenient for installation.

[0022] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0023] Embodiment 1:

[0024] A small hoistway elevator straight beam comprises an A surface 1, a B surface 2 integrally bent and formed on both sides of the A surface 1 and perpendicular to the A surface 1, and a C surface 3 integrally bent and formed on a side of the B surface 2 away from the A surface 1 and perpendicular to the B surface 2, wherein a cable groove 4 is formed between the A surface 1, the B surface 2 and the C surface 3 for cables to pass through, wherein:

[0025] A surface 1 is provided with an upper beam mounting hole 5, a first guide shoe mounting hole 6, a first safety gear mounting hole 7, a hollow hole 8, a process hole 12, a second safety gear mounting hole 9, a second guide shoe mounting hole 10 and a lower beam mounting hole 11 from top to bottom, wherein:

[0026] Upper beam mounting hole 5, used for mounting with the upper beam;

[0027] The first guide shoe mounting hole 6 and the second guide shoe mounting hole 10 are for mounting the guide shoe 18, and include an insertion hole 14, an embedding groove 15 and a locking hole 16. The embedding grooves 15 are two and are arranged below the insertion hole 14 and communicate with the insertion hole 14. The locking hole 16 is arranged between the two embedding grooves 15.

[0028] The working principle of the guide shoe 18 installation hole of the present application is: when installing the guide shoe 18, first extend it into the insertion hole 14, then move downward to be embedded in the two embedding grooves 15, and finally lock the guide shoe 18 through the locking hole 16 by the locking member, so that the guide shoe 18 is more convenient to install and is more firmly fixed;

[0029] The first safety gear mounting hole 7 and the second safety gear mounting hole 9 are for mounting the safety gear 17 and include four inclined waist-shaped holes;

[0030] The working principle of the safety clamp 17 after being installed in the safety clamp mounting hole of the present application is as follows: when in a normal state, the safety clamp 17 is at the lowest position of the waist-shaped mounting hole, and a certain gap is left between the moving side and the fixed side of the safety clamp 17 and the middle guide rail, so the guide rail is not in contact with the safety clamp 17 at this time; when the safety clamp 17 is triggered, the roller on the moving side of the safety clamp 17 will move along the slope, and when it moves to a certain distance, the roller will contact the guide rail, but at this time, the fixed side of the safety clamp 17 is still separated from the guide rail, and the roller will continue to move along the slope, so that the roller will squeeze the guide rail, and the guide rail will give the safety clamp 17 a reaction force, so that the safety clamp 17 moves in the waist-shaped mounting hole, and when it moves to a certain distance, the fixed side of the safety clamp 17 will contact the guide rail, and at this time, the moving side and the fixed side of the safety clamp 17 are in contact with the guide rail, and the safety clamp 17 does not move in the waist-shaped mounting hole, and is in a stable braking state, so that the force on the guide rail is also relatively uniform;

[0031] Hollow hole 8, for installation of the operation box;

[0032] Process hole 12 is used to reduce material usage and reduce production costs;

[0033] The lower beam mounting hole 11 is used for mounting in cooperation with the lower beam.

[0034] All the mounting holes of the present application are arranged on the A surface 1 and are arranged vertically along the A surface 1, so that the overall width of the straight beam is smaller, and thus the overall space occupied by the straight beam is smaller.

[0035] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the present invention.

[0036] For those skilled in the art, various changes and modifications will undoubtedly be obvious after reading the above description. Therefore, the attached claims should be regarded as covering all changes and modifications to the true intent and scope of the utility model. Any and all equivalent ranges and contents within the scope of the claims should be considered to still be within the intent and scope of the utility model.
