Description

Technical Field

[0001] This utility model relates to the field of enclosed elevator technology, specifically to an enclosed elevator designed to prevent dry-running. Background Technology

[0002] A cabin elevator is a very convenient and widely used vertical transportation tool. Also known as a lift or vertical elevator, it is an indispensable means of transportation in modern buildings.

[0003] A novel anti-free-spinning elevator (application number: 202320941751.8) electrically connects the power output terminal of the receiving control circuit to the power input terminal of the elevator body's motor. This invention prevents the problem of existing elevators being unable to prevent free-spinning and achieves energy saving. However, the aforementioned issues persist. When using an elevator, the elevator is raised and lowered by pulling a steel wire rope. At this time, the steel wire rope groove is in contact with the roller, and the rolling rotation is used to retract and extend the steel wire rope. When the roller rotates under force, it is easy for the roller to spin freely, which affects the retraction and extension of the steel wire rope and makes it difficult to move the elevator stably. The free-spinning of the roller easily affects the retraction and extension of the steel wire rope, and when the steel wire rope is pressed, it is not easy to buffer the downward force of the pressure roller. The strong pressing can easily make it difficult for the steel wire rope to move, thus affecting the operation of the elevator. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of existing technologies, such as the inconvenience of stable movement of the elevator car, the easy interference of the winding and unwinding of the wire rope due to the free rotation of the rollers, the difficulty in buffering the downward force of the pressure rollers, and the difficulty of moving the wire rope due to strong pressing, which in turn affects the operation of the elevator car. Therefore, this utility model proposes an elevator car that prevents free rotation.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a cabin elevator to prevent dry-spinning, comprising a plate, a shell fixedly connected to the top of the plate, a worm gear rotatably connected to one side of the inner wall of the shell via a pin, two rollers provided in front of the worm gear, the rear end of one roller rotatably connected to the rear end of the inner wall of the shell via a pin, and the rear end of the other roller fixedly connected to the front end of the worm gear, a steel wire rope attached to one side of the outer wall of the roller, the outer wall of the steel wire rope being clearance-fitted with one side of the inner wall of the plate, a slide rod fixedly connected to one side of the top of the plate, the top of the slide rod being fixedly connected to one side of the inner wall of the shell, one end of the steel wire rope being fixedly connected to the cabin elevator, and a clamping structure provided on one side of the slide rod.

[0007] Preferably, the clamping structure includes a horizontal plate, one inner wall of which is slidably engaged with the upper outer wall of the slide rod. Pressure rollers are rotatably connected to the inner walls of both ends of the horizontal plate via bearings. The front end of one pressure roller is fixedly connected to the output end of a motor, and the rear end of the motor is fixedly connected to one side of the front end face of the horizontal plate. The bottom of the pressure roller is in contact with the top side of the wire rope. A vertical rod is fixedly connected to the bottom side of the horizontal plate. A straight plate is fitted with a gap at the lower outer wall of the vertical rod, and a spring is fitted with a gap at the upper outer wall of the vertical rod. The upper and lower ends of the spring are fixedly connected to the bottom side of the horizontal plate and the top side of the straight plate, respectively.

[0008] Preferably, a square rod is fixedly connected to the bottom of the straight plate, and a cylindrical body is fitted with the upper part of the outer wall of the square rod with a clearance fit.

[0009] Preferably, the bottom of the cylinder is fixedly connected to one side of the top of the plate, the bottom inner wall of the square rod is threaded with a threaded rod, the bottom of the threaded rod is fixedly connected to the output end of the motor three, and the top of the motor three is fixedly connected to one side of the bottom of the plate.

[0010] Preferably, a worm is meshed with one side of the worm gear, and the lower outer wall of the worm is rotatably connected to the inner wall of one side of the plate through a bearing.

[0011] Preferably, the outer wall of the worm is rotatably connected to the inner wall of the top side of the housing via a bearing, the top of the worm is fixedly connected to the output end of the second motor, and the bottom of the second motor is fixedly connected to the top side of the housing.

[0012] The present invention proposes an anti-free-spinning elevator, the beneficial effects of which are as follows: through the cooperation of the plate, shell, worm gear, worm, motor two, slide bar, square bar, cylinder, threaded rod, motor three, roller, wire rope, elevator, and clamping structure, the device can be used such that when in use, motor three drives the threaded rod to rotate, the threaded rod drives the square bar to move downward, the square bar drives the straight plate to move downward, and then the straight plate drives the pressure roller to move downward. The pressure roller is pressed against the top side of the wire rope. Motor two drives the worm to rotate, the worm drives the worm wheel to rotate, the worm wheel drives the roller on one side to rotate, and motor one drives the pressure roller on one side to rotate, thereby realizing the stable winding and unwinding of the wire rope, facilitating the stable movement of the elevator, and preventing the roller from spinning freely and affecting the winding and unwinding of the wire rope.

[0013] Through the cooperation of rollers, slide bars, and clamping structures, this device can be used by a motor driving a threaded rod to rotate and move. The threaded rod drives a square rod to move downward, which in turn drives a straight plate to move downward. This causes the horizontal plate to drive the pressure roller to move downward, and the pressure roller clamps the wire rope. At this time, the spring setting can buffer the clamping force, which helps to buffer the downward pressure of the pressure roller and avoids the wire rope from being difficult to move due to strong clamping, thus avoiding affecting the operation of the elevator.

[0024] The top of the worm gear 4 is fixedly connected to the output end of the second motor 5, and the bottom of the second motor 5 is fixedly connected to one side of the top of the housing 3. The model of the second motor 5 depends on the actual use. There are two rollers 7 in front of the worm wheel 6. Multiple grooves are machined on the inner side of the rollers 7. The grooves are used to limit the wire rope 8. The rear end of one roller 7 is rotatably connected to the rear end of the inner wall of the housing 3 through a pin. The rear end of the other roller 7 is fixedly connected to the front end of the worm wheel 6.

[0025] A steel wire rope 8 is attached to one side of the outer wall of the roller 7. The outer wall of the steel wire rope 8 is in clearance fit with the inner wall of one side of the plate 1. A slide rod 10 is fixedly connected to the top side of the plate 1. The top of the slide rod 10 is fixedly connected to the top side of the inner wall of the shell 3. One end of the steel wire rope 8 is fixedly connected to the elevator car 14. A clamping structure 2 is provided on one side of the slide rod 10. The clamping structure 2 facilitates the stable movement of the elevator car 14 and prevents the roller 7 from spinning idly, which would affect the winding and unwinding of the steel wire rope 8.

[0026] The clamping structure 2 includes a horizontal plate 2a4. The inner wall of one side of the horizontal plate 2a4 is slidably engaged with the upper part of the outer wall of the slide rod 10. The inner walls of both ends of the horizontal plate 2a4 are rotatably connected to pressure rollers 2a5 through bearings. The front end of one side of the pressure roller 2a5 is fixedly connected to the output end of the motor 2a6. The model of the motor 2a6 is determined according to the actual use. The rear end of the motor 2a6 is fixedly connected to one side of the front end face of the horizontal plate 2a4.

[0027] A vertical rod 2a2 is fixedly connected to one side of the bottom of the horizontal plate 2a4. A straight plate 2a1 is fitted with the lower outer wall of the vertical rod 2a2 with a gap. A square rod 13 is fixedly connected to the bottom of the straight plate 2a1. A cylinder 9 is fitted with the upper outer wall of the square rod 13 with a gap. The inner top wall of the cylinder 9 acts as a limiter when the square rod 13 moves up and down under force. The bottom of the cylinder 9 is fixedly connected to one side of the top of the plate 1. A threaded rod 11 is threadedly connected to the inner bottom of the square rod 13. The bottom of the threaded rod 11 is fixedly connected to the output end of the motor 12.

[0028] The top of motor 312 is fixedly connected to the bottom side of plate 1. The model of motor 312 is determined according to the actual use.

The upper and lower ends of spring 2a3 are fixedly connected to the bottom side of horizontal plate 2a4 and the top side of vertical plate 2a1, respectively, to facilitate the stable movement of the elevator car 14 and prevent the roller 7 from spinning idly and affecting the winding and unwinding of wire rope 8.

[0029] Working principle:

[0030] When moving the elevator 14:

[0031] One end of the wire rope 8 is connected to the external counterweight structure, and the other end is connected to the top of the elevator car 14. Motor 3 12 starts working, driving the threaded rod 11 to rotate. The threaded rod 11 drives the square rod 13 to move downward, and the square rod 13 drives the straight plate 2a1 to move downward. In turn, the straight plate 2a1 drives the pressure roller 2a5 to move downward. The pressure roller 2a5 is pressed against the top side of the wire rope 8. The spring 2a3 can provide a certain buffer to avoid the strong pressing force affecting the movement of the wire rope 8. Motor 2 5 starts working, driving the worm gear 4 to rotate. The worm gear 4 drives the worm wheel 6 to rotate, and the worm wheel 6 drives the roller 7 on one side to rotate. Motor 1 2a6 starts working, driving the pressure roller 2a5 on one side to rotate, thereby realizing the stable winding and unwinding of the wire rope 8, preventing the roller 7 from spinning freely, and thus enabling the elevator car 14 to move up and down stably.

[0032] Example 2:

[0033] See attached document Figure 1-6 In this embodiment, a cabin elevator with anti-dry rotation is provided, wherein the clamping structure 2 may further include a roller 2b1, the rear end of which is rotatably connected to the rear end of the inner wall of one side of the plate 1 via a pin, and one end of the roller 2b1 is in contact with the lower side of the wire rope 8.

[0034] Working principle:

[0035] When the wire rope 8 moves under force, the circular roller 2b1 can guide the wire rope 8, and the circular roller 2b1 can reduce the wear between the wire rope 8 and the plate 1.
