Description

Technical Field

[0001] This utility model relates to the field of elevator technology, specifically to a forced-drive elevator. Background Technology

[0002] Existing forced-drive elevator structures generally employ a combination of mechanical safety clamps and speed governors, such as... Figure 1 As shown, the car is connected to the gantry frame, guide shoes are fixed to the upper and lower ends of the vertical beams on both sides of the gantry frame, and guide rails are fixed to the hoistway frame. The guide shoes slide up and down along the guide rails. The mechanical safety gear is fixed to the vertical beams, and the speed governor and tensioning device are connected to the safety gear through a linkage mechanism. In an emergency, the speed governor activates, thereby driving the safety gear to brake and stop the entire elevator. This type of elevator has a slow response and low hoistway space utilization.

[0003] Many elevator manufacturers have begun to research and design electronic safety clamps. There are many common structures and models of electronic safety clamps, including AH01, AH01Z, AH02Z, AH03Z, AH04, AH04Z, AK01AF / AC, AK01BF / BC, AK01ZA, AK01ZB, AK04, AK05, AK05Z, AK06A / B, AK06AZ / BZ, and AK07. These safety clamp models are suitable for elevators with different speeds and loads. The selection depends on the specific speed and load. For example, the electronic safety clamp model AK06AZ / BZ has a rated speed of ≤2.5m / s, a total permissible mass of 600-3200kg, and a guide rail width of 9-19mm.

[0004] Electronic safety clamps are faster and more flexible to use than mechanical safety clamps. They eliminate the traditional structure of speed limiters and tensioning devices. Although eliminating speed limiters and tensioning devices frees up some space, the size of the car is still constrained by essential mechanisms and components such as gantry components and guide rails. Therefore, it is necessary to design a forced-drive elevator that can increase the size of the car while using electronic safety clamps. Utility Model Content

[0005] To overcome the aforementioned problems, the purpose of this utility model is to provide a forced-drive elevator with a convex car shape. The rear half of the car extends to both sides, making the space where the speed governor was originally placed also part of the car. The first connecting plate that originally fixed the crossbeam and the column is also moved to the intersection of the guide rail and the crossbeam, thereby further improving the utilization rate of the shaft space.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a forced-drive elevator, comprising a shaft frame with a load-bearing beam on the upper part, a gantry frame, a car installed in the gantry frame, an electronic safety brake, and guide rails installed on the two inner sides of the shaft frame; the shaft frame includes a crossbeam and a column, the car is convex in shape, and grooves are provided at the front ends of both sides, the guide rails on both sides are respectively located in the grooves on both sides of the car, and a first connecting plate is provided at the junction of the guide rail and the crossbeam to fix the crossbeam and the column, and the guide rail is fixed to the first connecting plate by a guide rail pressure plate.

[0007] The car is designed with a convex shape, and the rear half of the car extends to both sides, so that the space originally used to house the speed limiter also becomes part of the car, effectively utilizing the hoistway space. The first connecting plate that originally fixed the crossbeam and the column has also been moved to the junction of the guide rail and the crossbeam, further improving the utilization rate of the hoistway space.

[0008] Furthermore, the car includes a car floor, which is convex in shape.

[0009] Furthermore, the gantry frame includes a vertical beam, and the car floor is connected to the vertical beam via a second connecting plate.

[0010] Furthermore, each of the first connecting plates corresponds to a set of guide rail pressure plates, and each set of guide rail pressure plates consists of two plates, which are symmetrically fixed on both sides of the guide rail.

[0011] Furthermore, the first connecting plate has a first connecting hole at one end for connecting to the crossbeam, a second connecting hole at the other end for connecting to the column, and a third connecting hole in the middle for fixing to the guide rail pressure plate.

[0012] Furthermore, the drive unit is equipped with drive wheels, and the drive unit is located on the outer pit ground of the shaft frame, which does not occupy shaft space and improves shaft utilization.

[0013] Furthermore, it also includes a first guide wheel, a second guide wheel, a drive unit, and a wire rope. The first guide wheel and the second guide wheel are fixed on the load-bearing beam. One end of the wire rope is fixed on the drive wheel, and the other end is wound around the second guide wheel and the first guide wheel in sequence, and then fixed to the gantry frame through the rope end.

[0014] The drive unit drives the drive wheel to rotate, which in turn drives the gantry and the car to move upward via the wire rope; conversely, it drives the car to move downward.

[0015] Furthermore, a gasket is provided between the guide rail pressure plate and the first connecting plate.

[0016] Furthermore, the thickness of the second connecting plate is 10mm.

[0017] The beneficial effects of this utility model are:

[0018] 1. This utility model uses an electronic safety clamp, eliminating the need for a speed limiter. The car is designed with a convex shape, and the rear half of the car extends to both sides, making the space where the speed limiter was originally placed also part of the car, thus effectively utilizing the hoistway space. The first connecting plate that originally fixed the crossbeam and the column is also moved to the junction of the guide rail and the crossbeam, further improving the utilization rate of the hoistway space.

[0019] 2. The drive unit is set on the ground of the foundation pit outside the shaft frame, which does not occupy the shaft space and improves the utilization rate of the shaft. Attached Figure Description

[0031] The car 11 is designed in a convex shape, with the rear half of the car 11 extending to both sides, so that the space originally used to house the speed limiter also becomes part of the car 11, thus making effective use of the hoistway space.
