Description

Technical Field

[0001] The present invention relates to the technical field of elevators, and in particular to a structure of a forced-drive elevator. Background Art

[0002] Vertical elevators can be divided into traction elevators, forced-drive elevators, hydraulic elevators, and screw elevators according to the driving mode. At present, most elevators on the market adopt traction elevators because traction elevators have many advantages: good stability, good safety performance, energy saving, mature technology, etc. The structure of a traction elevator is that both ends of a steel wire rope are fixed with spring rope heads, one end bypasses the car, the other end bypasses the counterweight, and the middle bypasses the main machine. Both the car and the counterweight have vertical guide rails. The up and down movement of the car is realized by the forward and reverse rotation of the main machine. The driving force is the friction between the steel wire rope and the main machine wheel to drag the steel wire rope, and the movement of the steel wire rope drives the car and the counterweight to move relatively up and down. Due to the structure of the counterweight in a traction elevator, the requirement for the size of the entire elevator shaft will increase. That is, for the same-sized shaft, the area of the car made will be smaller than that of elevators with other structures.

[0003] For general household elevators, such as villa elevators, the reserved shafts are very small. When the shaft is extremely small, it is impossible to design and install a traction elevator, and other structures of elevators need to be adopted, generally forced-drive elevators or screw elevators. The running speed of screw elevators is slow, the cost is high, the noise is large, and the maintenance cost is high. Most of them still adopt forced-drive elevators on the market. At present, the utilization rate of the shaft for forced-drive elevators on the market is still not high enough. When the shaft is extremely small, the car of the elevator made is small, the riding experience is poor, and the practicability is not great. Most of all the forced-drive structures on the market are the traditional gantry type. Compared with traction elevators, only the counterweight is removed, and a small part is the backpack frame structure, which also only cancels the counterweight, and the utilization rate of the entire shaft has not reached the maximum. Summary of the Invention

[0004] Based on the above, the purpose of the present invention is to provide a structure of a forced-drive elevator to improve the space utilization rate of the shaft.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] The present invention provides a structure of a forced-drive elevator, including:

[0007] A guiding component, arranged at the top of the shaft;

[0008] A driving component, arranged at the bottom of the shaft;

[0009] Guide rails, configured to extend along the vertical direction of the shaft;

[0010] The car is slidably arranged on the guide rail. The output end of the driving assembly is provided with a driving steel wire rope, and the other end of the driving steel wire rope bypasses the guiding assembly and is connected to the top of the car.

[0011] The safety assembly includes a tensioning wheel device, a speed limiter wheel and a speed limiting steel wire rope.

[0012] Wherein, the tensioning wheel device includes a base. The left and right sides of the base are respectively provided with a left guide wheel and a right guide wheel. The left guide wheel and the right guide wheel are respectively located on both sides of the guide rail. The front side of the base is provided with a front guide wheel, and the front guide wheel is correspondingly located on the front side of the guide rail. The speed limiting steel wire rope sequentially bypasses the left guide wheel, the front guide wheel and the right guide wheel.

[0013] Further, the base includes a first fixing plate, a spring upper plate, a spring lower plate, a second fixing plate, a third fixing plate and a switch trigger plate. The first fixing plate is connected to the guide rail. The spring upper plate is connected to the first fixing plate. The switch trigger plate is connected to the first fixing plate. An elastic member is arranged between the spring upper plate and the spring lower plate. The second fixing plate is connected to the spring lower plate. The left guide wheel and the right guide wheel respectively rotate on both sides of the second fixing plate. The third fixing plate is connected to the second fixing plate. The front guide wheel is rotatably arranged on the front side of the third fixing plate. A travel switch is further arranged on the third fixing plate, and the travel switch is located above the switch trigger plate.

[0014] Further, the elastic member includes a limit bolt, a limit nut, a limit pad and a tension spring. The limit bolt sequentially passes through the spring upper plate, the limit pad and the tension spring, and its tail is locked by the limit nut.

[0015] Further, three groups of the elastic members are provided, and the three groups of elastic members are arranged in a triangular layout.

[0016] Further, the safety assembly further includes a speed limiter, a lifting arm and a safety clamp. The speed limiter is arranged on the top of the guide rail. The lifting arm and the safety clamp are arranged on the outside of the car. When the speed of the speed limiting steel wire rope exceeds the set speed of the speed limiter, the lifting arm will drive the safety clamp to act, and the safety clamp can clamp the guide rail.

[0017] Further, the car includes a car top, a car bottom and car walls. The car top is connected to an upper door beam, the car bottom is connected to a lower door beam, the car walls are connected to door vertical beams, and the upper and lower sides of the door vertical beams are respectively connected to the upper door beam and the lower door beam.

[0018] Further, the guiding assembly includes:

[0019] Two groups of guiding beams arranged at the top of the hoistway;

[0020] A first rotating shaft arranged between the two groups of guiding beams. Two groups of first reversing wheels are rotatably arranged on the first rotating shaft, and the first reversing wheels are located above the driving assembly;

[0021] A second rotating shaft arranged between the two groups of guiding beams. Two groups of second reversing wheels are rotatably arranged on the second rotating shaft, and the second reversing wheels are located above the car;

[0022] Two groups of driving steel wire ropes are provided, and each one-by-one bypasses the first reversing wheel and the second reversing wheel.

[0023] Further, the driving assembly includes a main frame fixed at the bottom of the hoistway. A main machine body is arranged on the main frame. A driving mechanism and a winding disc are arranged on the main machine body. The output end of the driving mechanism is connected to the winding disc, and one end of each of the two groups of driving steel wire ropes is respectively connected to both sides of the winding disc one-by-one.

[0025] Further, a rope socket is arranged between the driving steel wire rope and the car.

[0026] The beneficial effects of the present invention are as follows:

[0027] (1) In the present invention, the speed limit steel wire rope bypasses the left guide wheel, the front guide wheel and the rear guide wheel of the tensioning wheel device. The speed limit steel wire rope crosses the guide rail, effectively utilizing the space, effectively improving the utilization rate of the hoistway, and enabling the car to be designed larger.

[0028] (2) A travel switch is arranged on the tensioning wheel device. In the normal state, that is, when the speed limit steel wire rope is in a tensioned state, at this time, the elastic member is in a compressed state, and there is a gap between the switch trigger plate and the travel switch. When the speed limit steel wire rope breaks or is in a slack state, under the action of the spring force, the travel switch moves downward. At this time, the travel switch collides with the switch trigger plate, and the travel switch is triggered, transmitting a signal to the safety circuit of the elevator. At this time, the elevator circuit is disconnected to prevent potential safety hazards;

[0029] (3) The positions corresponding to the upper beam, lower beam and vertical beam of the doorway are designed as spaces where people can stand, increasing the effective usable area of the car. Description of the Drawings

The first fixing plate 514 is connected to the guide rail 3. A plurality of mounting holes are provided on the first fixing plate 51, the spring upper plate 515 is connected to the first fixing plate 514, and the spring upper plate 515 can be connected to the first fixing plate 514 by welding. The switch trigger plate 518 is connected to the first fixing plate 514, and the switch trigger plate 518 is connected to the first fixing plate 514 by screws or the like. An elastic member 519 is provided between the spring upper plate 515 and the spring lower plate 516. The second fixing plate 517 is connected to the spring lower plate 516. The left guide wheel 511 and the right guide wheel 512 respectively rotate on both sides of the second fixing plate 517. The third fixing plate 5172 is connected to the second fixing plate 517. The front guide wheel 513 is rotatably provided on the front side of the third fixing plate 5172. A travel switch 54 is further provided on the third fixing plate 5172.

In the normal state, that is, when the speed-limiting wire rope 52 is in a tensioned state, at this time the elastic member 519 is in a compressed state, and there is a gap between the switch trigger plate 518 and the travel switch 54. When the speed-limiting wire rope 52 breaks or is in a slack state, under the action of the spring force, the travel switch 54 moves downward. At this time, the travel switch 54 collides with the switch trigger plate 518, and the travel switch 54 is triggered, transmitting a signal to the safety circuit of the elevator. At this time, the elevator circuit is disconnected to prevent safety hazards.

Specifically, the speed limit wire rope 52 is respectively hinged to the safety clamp 56 and the lifting arm 55 through a lifting plate (not shown in the figure). The lifting arm 55 and the safety clamp 56 are hinged to each other. When the speed of the speed limit wire rope 52 exceeds the set speed of the speed limiter 57, the speed limiter 57 will lock the speed limit wire rope 52.
