Description

Technical Field

[0001] The utility model belongs to the technical field of suspension cages, and relates to a variable-direction suspension cage, in particular to a numerically controlled variable-direction suspension cage. Background Art

[0002] A numerically controlled variable-direction suspension cage is a lifting device integrating numerical control technology and variable-direction function, mainly used in vertical or inclined transportation operations. The numerically controlled variable-direction suspension cage mainly consists of a lifting mechanism and a suspension cage. The lifting mechanism includes key components such as a motor, a reducer, a main drum, and an auxiliary drum. The motor is axially connected to the reducer, and the reducer is then meshed and connected to the main drum through gears to achieve power transmission. Suspension ropes are wound on both the main drum and the auxiliary drum, and the lower ends of the suspension ropes are fixed on the suspension rope fixing seats at the top of the suspension cage.

[0003] In the numerically controlled variable-direction suspension cage, the main drum is used to lift and lower the suspension cage. When the motor starts, it drives the main drum to rotate through the reducer, and then winds or releases the suspension rope to achieve the lifting and lowering of the suspension cage. The auxiliary drum plays an auxiliary role in the main drum and provides safety protection for the suspension cage in case of emergency, ensuring the normal operation of the suspension cage and the safety of personnel.

[0004] The existing numerically controlled variable-direction suspension cage has limited angle adjustment, limited emergency braking effect in case of danger, and insufficient safety protection due to its open structure.

[0005] Based on this, we propose a numerically controlled variable-direction suspension cage, which can adjust the angle of the suspension cage more flexibly, has a better emergency braking effect in case of danger, a semi-enclosed structure to prevent the device from accumulating dust, and better safety protection. Summary of the Invention

[0006] The purpose of the utility model is to address the above problems existing in the prior art and propose a numerically controlled variable-direction suspension cage. The technical problem to be solved by the utility model is: how to achieve more flexible adjustment of the angle of the suspension cage, better emergency braking effect in case of danger, a semi-enclosed structure to prevent the device from accumulating dust, and better safety protection.

[0007] The purpose of the utility model can be achieved by the following technical solutions:

[0008] A CNC changing direction cage comprises an outer protection cylinder mechanism, a main drum and an auxiliary drum, wherein the main drum and the auxiliary drum are both located inside the outer protection cylinder mechanism, and a lifting rope is provided on the main drum and the auxiliary drum, and a safety rope is also provided on the auxiliary drum, and a plurality of connecting mechanisms are respectively connected between the lifting rope and the safety rope and the cage mechanism, and a plurality of auxiliary braking mechanisms are provided inside the outer protection cylinder mechanism, and the auxiliary braking mechanisms correspond to the positions of the main drum and the auxiliary drum respectively, and a motor 1 and a quick engagement mechanism are provided on the left side of the outer protection cylinder mechanism, and the quick engagement mechanism is arranged on the auxiliary drum, and the quick engagement mechanism and the main drum are connected through a gear pair transmission, and a reducer is connected between the motor 1 and the main drum, and the main drum and the auxiliary drum are connected through a quick engagement mechanism, and a ratchet and pawl type safety gate is provided on the right side of the main drum and the auxiliary drum, and the safety gate is located inside the outer protection cylinder mechanism, and an overload limiter is provided on the right side of the outer protection cylinder mechanism.

[0009] The working principle of the utility model is as follows: during normal operation, the safety rope is not subjected to tension, the safety gate does not operate, the motor 1 is started, the motor 1 drives the main drum to rotate through the reducer, and drives the auxiliary drum to rotate through the quick engagement mechanism, thereby driving the cage mechanism to descend horizontally and uniformly to a suitable height through the suspension rope and the safety rope, the motor 1 stops rotating, the quick engagement mechanism is retracted, the mutual engagement between the main drum and the auxiliary drum is released, and at the same time the quick engagement mechanism brakes the auxiliary drum, the motor 1 is started again, the main drum is driven to rotate through the reducer, thereby changing the lateral angle of the cage mechanism through the suspension rope on the main drum;

[0010] When an accident such as broken shaft or broken gear occurs between the motor and the reducer, the cage mechanism drops freely under the action of its own weight. When the speed of the main drum reaches a certain level, the safety gate works to prevent the main drum and auxiliary drum from rotating. At the same time, the auxiliary brake mechanism is pushed out and inserted into the main drum and auxiliary drum to prevent them from rotating.

[0011] The outer protective cylinder mechanism includes an outer protective cylinder body, a left cylinder wall is fixed on the left side of the outer protective cylinder body, motor one is fixed on the outside of the left cylinder wall, the output shaft of motor one passes through the left cylinder wall, an inner cylinder wall is fixed inside the outer protective cylinder body, a quick engagement mechanism and a reducer pass through the inner cylinder wall, a right cylinder wall is fixed on the right side of the outer protective cylinder body, a safety gate is fixed on the inside of the right cylinder wall, and an overload limiter is fixed on the outside of the right cylinder wall.

[0012] With the above structure, the outer protective tube body is used to protect the internal structure of the outer protective tube body. When the lifting weight reaches about 90% of the rated lifting weight, an audio and light warning signal is issued. When the lifting weight reaches about 105% of the rated lifting weight, the motor is automatically cut off.

[0013] The main drum includes a main drum body. The right end of the main drum body is rotatably arranged inside the right cylinder wall. A main drum rotating shaft is fixed to the left side of the main drum body. The left side of the main drum rotating shaft is drivingly connected to the output shaft of the first motor through a speed reducer. Two lifting ropes are wound around the main drum body.

[0014] With the above structure, when the first motor is started, the first motor drives the main drum rotating shaft to rotate through the speed reducer, drives the main drum body to rotate, and thus drives the two lifting ropes on the main drum body to rise or fall synchronously.

[0015] When accidents such as shaft breakage or gear tooth breakage occur between the first motor and the speed reducer, the cage mechanism freely descends under its own weight. When the rotation speed of the main drum body reaches a certain value, the safety brake brakes the main drum body.

[0016] The auxiliary drum includes an auxiliary drum body. The right end of the auxiliary drum body is rotatably arranged inside the right cylinder wall. A safety rope and one of the lifting ropes are wound around the auxiliary drum body. A number of braking stop shafts are fixed to the left sides of the auxiliary drum body and the main drum body and are arranged circumferentially and evenly. An auxiliary drum rotating shaft is fixed to the left side of the auxiliary drum body. A braking cooperation seat and a meshing cooperation seat are sequentially fixed to the auxiliary drum rotating shaft from left to right.

[0017] With the above structure, when accidents such as shaft breakage or gear tooth breakage occur between the first motor and the speed reducer, the cage mechanism freely descends under its own weight.

[0018] The quick meshing mechanism includes a first push rod motor. The first push rod motor is fixed to the outside of the left cylinder wall. The output shaft of the first push rod motor passes through the left cylinder wall and is fixed to a connecting shaft. A connecting rod is fixed to the connecting shaft. The connecting rod is rotatably arranged on the left cylinder wall. The connecting rod is located between the braking cooperation seat and the meshing cooperation seat. A braking gear is fixed to one end of the connecting rod. The direction and specifications of the braking gear correspond to those of the braking cooperation seat. A meshing gear is rotatably arranged at the other end of the connecting rod. The direction and specifications of the meshing gear correspond to those of the meshing cooperation seat. The meshing gear is engaged inside the meshing cooperation seat. At the same time, the meshing gear is drivingly connected to the main drum rotating shaft through a gear pair.

[0019] With the above structure, the main drum rotating shaft, the gear pair, and the meshing gear are drivingly connected to the auxiliary drum rotating shaft, so as to realize the driving connection between the main drum rotating shaft and the auxiliary drum rotating shaft. When the output shaft of the first push rod motor retracts, the meshing gear disengages from the meshing cooperation seat, and at the same time, the braking gear engages with the meshing cooperation seat, realizing the braking of the auxiliary drum rotating shaft by the braking gear.

[0020] The auxiliary braking mechanism includes a push rod motor II, which is fixed on the left side of the inner cylinder wall. The push rod of the push rod motor II passes through the inner cylinder wall, and a brake pin is fixed on the push rod of the push rod motor II. The positions of the brake pins correspond to the positions of the brake blocking shafts on the main drum and the auxiliary drum respectively.

[0021] With the above structure, when the safety brake brakes the main drum body and the auxiliary drum body, the push rod motor II pushes out, driving the brake pin to insert into the left side inside of the main drum body and the auxiliary drum shaft, and cooperating with the brake blocking shafts on the drum body and the auxiliary drum shaft to brake the rotation of the drum body and the auxiliary drum shaft.

[0022] The connecting mechanism includes a connecting pin shaft and a U-shaped connecting piece. The connecting pin shaft passes through the U-shaped connecting piece, and the connecting pin shaft is located below the U-shaped connecting piece. A suspension rope connecting piece is rotatably provided on the upper side of the U-shaped connecting piece through a connecting pin.

[0023] With the above structure, the connecting pin shaft and the U-shaped connecting piece cooperate to keep the cage mechanism horizontal transversely, and the U-shaped connecting piece and the suspension rope connecting piece cooperate to keep the cage mechanism horizontal longitudinally.

[0024] The cage mechanism includes a cage body and a plurality of uniformly arranged connecting seats. The connecting pin shaft passes through the connecting seats, and the connecting seats are fixed on the cage body.

[0025] With the above structure, the support balance arm can be automatically adjusted in angle by sensing and outputting signals or manually adjusted by turning the handwheel to ensure that the cage body always remains vertical in the inclined flue.

[0037] The following are specific embodiments of the present utility model and in conjunction with the accompanying drawings, the technical solutions of the present utility model will be further described, but the present utility model is not limited to these embodiments.

The main drum 7 and the auxiliary drum 12 are both located inside the outer protection cylinder mechanism 1. Hoisting ropes 10 are provided on both the main drum 7 and the auxiliary drum 12. At the same time, a safety rope 13 is also provided on the auxiliary drum 12. The hoisting ropes 10 and the safety rope 13 are respectively connected to the cage mechanism 2 through a number of connecting mechanisms 9. The main drum 7 and the auxiliary drum 12 connect the cage mechanism 2 through the hoisting ropes 10 and the safety rope 13.

At the same time, the quick engagement mechanism 4 is connected to the main drum 7 through a gear pair transmission. A speed reducer 5 is connected between the motor 1 3 and the main drum 7. The main drum 7 and the auxiliary drum 12 are connected through the quick engagement mechanism 4.

The safety brakes 8 are located inside the outer protection cylinder mechanism 1. An overload limiter 11 is provided on the right side of the outer protection cylinder mechanism 1.

[0039] In this embodiment, during normal operation, the safety rope 13 is not under tension and the safety brake 8 does not operate. Start the motor 1 3. The motor 1 3 drives the main drum 7 to rotate through the speed reducer 5, and drives the auxiliary drum 12 to rotate through the quick engagement mechanism 4. Thereby, the cage mechanism 2 is driven to descend horizontally and uniformly to an appropriate height through the hoisting ropes 10 and the safety rope 13. The motor 1 3 stops rotating, and the quick engagement mechanism 4 retracts, releasing the mutual engagement of the main drum 7 and the auxiliary drum 12. At the same time, the quick engagement mechanism 4 brakes the auxiliary drum 12. Start the motor 1 3 again, drive the main drum 7 to rotate through the speed reducer 5, and thereby change the lateral angle of the cage mechanism 2 through the hoisting rope 10 on the main drum 7;

[0040] When accidents such as shaft breakage or gear tooth breakage occur between the motor 1 3 and the speed reducer 5, the cage mechanism 2 freely descends under its own weight. When the rotation speed of the main drum 7 reaches a certain value, the safety brake 8 comes into play, preventing the main drum 7 and the auxiliary drum 12 from rotating. At the same time, the auxiliary braking mechanism 6 is pushed out and inserted into the main drum 7 and the auxiliary drum 12 to prevent the main drum 7 and the auxiliary drum 12 from rotating.

When the lifting weight reaches about 90% of the rated lifting weight, an audible and visual warning signal is issued. When the lifting weight reaches about 105% of the rated lifting weight, the motor 3 is automatically cut off.

The left side of the main drum rotating shaft 702 is drivingly connected to the output shaft of the motor 3 through a speed reducer 5. Two lifting ropes 10 are wound around the main drum body 701.

[0044] In this embodiment, when the motor 3 is started, the motor 3 drives the main drum rotating shaft 702 to rotate through the speed reducer 5, drives the main drum body 701 to rotate, and thus drives the two lifting ropes 10 on the main drum body 701 to rise or fall synchronously.

[0045] When accidents such as shaft breakage or gear tooth breakage occur between the motor 3 and the speed reducer 5, the cage mechanism 2 freely descends under its own weight.

[0049] In this embodiment, the main reel shaft 702, the gear pair and the meshing gear 404 are transmission connected with the auxiliary reel shaft 1202, thereby realizing the transmission connection between the main reel shaft 702 and the auxiliary reel shaft 1202. When the output shaft of the push rod motor 401 is retracted, the meshing gear 404 is released from the engagement with the meshing mating seat 1204, and at the same time, the brake gear 405 is engaged with the meshing mating seat 1204, thereby realizing the braking of the auxiliary reel shaft 1202 by the brake gear 405.

[0052] The connecting mechanism 9 includes a connecting pin 901 and a U-shaped connecting piece 902. The connecting pin 901 passes through the U-shaped connecting piece 902.

Several suspension rope connecting pieces 903 are respectively connected to the ends of the suspension rope 10 and the safety rope 13 at corresponding positions.

[0053] In this embodiment, the connecting pin 901 cooperates with the U-shaped connector 902 to keep the cage mechanism 2 horizontal in the lateral direction, and the U-shaped connector 902 cooperates with the rope connector 903 to keep the cage mechanism 2 horizontal in the longitudinal direction.

[0054] The cage mechanism 2 includes a cage body 201 and a plurality of evenly arranged connecting seats 204, the connecting pin shaft 901 passes through the connecting seat 204, the connecting seat 204 is fixed on the cage body 201, and a supporting balance arm 202 and a supporting roller 203 are fixed to one side of the cage body 201, wherein the supporting balance arm 202 is located on the upper side of the supporting roller 203.

When the rotation speed of the main drum body 701 reaches a certain level, the safety gate 8 works to prevent the main drum body 701 and the auxiliary drum body 1201 from rotating.
