Description

Technical Field

[0001] The present application relates to the technical field of monorail cranes, and in particular to a monorail crane system with multiple deceleration functions. Background Art

[0002] The monorail crane is a system that uses a special I-beam suspended above the roadway as a track, and is connected to a group of hanging vehicles with various functions, and is towed by traction equipment to run along the track. Its traction power can be provided by wire ropes, diesel engines, batteries or pneumatic devices.

[0003] The monorail crane itself has brakes and protective devices, but the monorail crane is heavy when it is running freely, its own weight is dozens of tons, and it exceeds 100 tons when in operating condition. The normal working speed should be slow, but in places with slopes, if the built-in brake device fails, it may cause the car to slip at a speed of more than 20 meters per second, which is extremely unsafe and may cause the car to be destroyed and people to die. The old monorail crane usually has two cabs in the front and back, each with a driver. There are also unmanned monorail cranes now, but when a slip accident occurs, it will cause great economic losses.

[0004] Therefore, there is an urgent need in the art for a deceleration system applied to a monorail crane, which can ensure the safety of the monorail crane as much as possible when slipping occurs and avoid accidents. Summary of the invention

[0007] Preferably, the primary deceleration mechanism includes a mounting frame, a housing and a sliding oil cylinder. The first driving member is a scissor lift table, which is detachably arranged on the side wall of the hanging track and the platform surface is on the side背离 the hanging track. The mounting frame is detachably arranged on the platform surface of the first driving member. A plurality of mounting grooves are spaced along the length direction of the hanging track on the mounting frame. The housing is fixedly sleeved on the outer wall of the sliding oil cylinder, and the housing is detachably arranged in the mounting groove and the piston rod of the sliding oil cylinder is arranged in the direction背离 the hanging track. The sliding oil cylinder is inclined with the side wall of the hanging track.

[0008] Furthermore, an assembly groove is formed along the length direction of the hanging track on the mounting frame, and the assembly groove is arranged on the same side as the mounting groove. At least one arc-shaped waist groove communicating with the assembly groove is formed on the side wall of the mounting groove facing the assembly groove.

[0010] Furthermore, the electromagnet core is in a "凵" shape or an "E" shape, the plane side of the electromagnet core faces the hanging track, and the opening side extends into the magnetic induction frame.

[0011] Furthermore, the magnetic induction frame and the primary deceleration mechanism are arranged at an interval up and down, and the primary deceleration mechanisms on both sides of the hanging track are arranged at an interval before and after along the length direction of the hanging track.

The primary reduction mechanism is used to initially decelerate the monorail crane as a whole, and the compression reaction force of the piston rod of the sliding cylinder is used to decelerate. When the driving member 1 is started, the driving member 2 drives the magnetic reduction mechanism close to the hanging rail. The magnetic reduction mechanism magnetizes the electromagnet core and uses the attraction between the electromagnet core and the steel hanging rail to generate a large friction force, thereby slowing down the monorail crane.

[0017] When the present invention is used, the movement of the primary deceleration mechanism and the magnetic induction deceleration mechanism is driven by drive one and drive two, so that the deceleration effect on the monorail crane can be avoided when the monorail crane is operating normally, thereby saving energy consumption.

[0018] When the present invention is used, the inertial force of the monorail crane during deceleration can be converted into electrical energy for storage through the regenerative braking energy storage power supply component to supply the electrical energy required for the operation of the deceleration device without the need for external power. As a result, the deceleration device can also achieve a good deceleration effect in the event of a power outage, further ensuring the safety of the monorail crane during operation.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical scheme and advantages of the embodiment of the present application clearer, the technical scheme of the embodiment of the present application will be clearly and completely described in conjunction with the drawings of the embodiment of the present application. Obviously, the described embodiment is a part of the embodiment of the present application, not all of the embodiments. Based on the described embodiment of the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of this application.

[0022] Unless otherwise defined, the technical terms or scientific terms used herein shall have the common meanings understood by persons with ordinary skills in the field to which this application belongs. The words "one" or "an" and the like used in the patent application specification and claims of this application do not indicate a quantity limitation, but indicate the existence of at least one.

[0023] The following is combined with Figure 1-5 This application is described in further detail.

[0024] Reference Figure 1A monorail crane system with multiple deceleration functions includes a monorail crane 1. The monorail crane 1 is provided with at least one cab, which is slidably mounted on a steel hanging rail 2 through a bogie 11 and a plurality of pulleys 12. Speed ​​sensors 8 are embedded and mounted on the side walls near the top on both sides of the cab's moving direction. A deceleration device 3 is installed between the side wall of the bogie 11 and the side wall of the hanging rail 2. The speed sensor 8 is used to monitor the overall movement speed of the monorail crane 1. When overspeeding occurs, the speed sensor 8 will promptly feed back the overspeed signal to the deceleration device 3, thereby achieving deceleration and braking of the monorail crane 1.

[0025] Reference Figure 1-Figure 5 The deceleration device 3 includes a primary deceleration mechanism 31 and a magnetic induction deceleration mechanism 32. The primary deceleration mechanism 31 is installed in multiple groups and is evenly arranged on the side walls of the hanging rail 2 on both sides along the length direction of the hanging rail 2. The primary deceleration mechanisms 31 on both sides of the hanging rail 2 are arranged in a front-to-rear interval along the length direction of the hanging rail 2. The primary deceleration mechanism 31 can move toward or away from the side wall of the hanging rail 2 to perform preliminary mechanical deceleration on the cab; the magnetic induction deceleration mechanism 32 is installed on the side wall of the bogie 11 facing the hanging rail 2 and is arranged with an upper and lower interval with the primary deceleration mechanism 31. The magnetic induction deceleration mechanism 32 can move toward or away from the hanging rail 2. The magnetic induction deceleration mechanism 32 generates magnetic friction between the magnetic induction deceleration mechanism 32 and the side wall of the hanging rail 2 by energizing to achieve braking. The bogie 11 is equipped with a driving member 15 and a driving member 2 16 for driving the primary deceleration mechanism 31 and the magnetic induction deceleration mechanism 32 to move. The driving member 15 and the driving member 2 16 are both connected to the speed sensor 8 signal.

[0026] Reference Figure 1-Figure 3 The primary reduction mechanism 31 includes a mounting frame 311, a shell 312 and a sliding cylinder 313. The driving member 15 adopts a scissor lift platform. The hanging track 2 is provided with a telescopic slot 21. The driving member 15 is detachably mounted in the telescopic slot 21 by means of bolts 5, and the platform surface is located on the side away from the telescopic slot 21. The mounting frame 311 is detachably mounted on the platform surface of the driving member 15 by means of bolts 5. A plurality of mounting slots 3111 are spaced apart on the mounting frame 311 along the sliding direction of the bogie 11. The shell 312 is fixedly sleeved on the outer wall of the sliding cylinder 313 by interference fit. The sliding cylinder 313 is detachably mounted in the mounting slot 3111 through the shell 312. The piston rod of the sliding cylinder 313 faces the hanging track 2, and the sliding cylinder 313 and the piston rod are inclined to the side wall of the hanging track 2. The driving member 15 drives the sliding cylinder 313 to extend into or out of the telescopic slot 21. When a vehicle rollback occurs, the speed sensor 8 senses the overspeed signal and transmits the overspeed signal to the first driving member 15. The first driving member 15 drives the sliding oil cylinder 313 in the primary deceleration mechanism 31 to extend out of the telescopic groove 21 on the side wall of the hanging rail 2. When the steering gear passes through the primary deceleration mechanism 31, the piston rod of the sliding oil cylinder 313 is pressed into the sliding oil cylinder 313 by the side wall of the bogie 11 and has a reverse acting force, thereby realizing the preliminary deceleration of the steering gear and the monorail crane 1. After the steering gear slides past, the piston rod of the sliding oil cylinder 313 extends out again.

[0027] Refer to Figure 2 and Figure 3 As shown in FIGS. 3 and 4, an assembly groove 3112 is formed in the mounting frame 311 along the length direction of the hanging rail 2. The assembly groove 3112 is formed on the same side as the mounting groove 3111. At least one arc-shaped waist groove 4 communicating with the assembly groove 3112 is formed on the side wall of the mounting groove 3111 facing the assembly groove 3112. Angle indicating scale lines 7 are formed on the inner wall of the mounting groove 3111 in the circumferential direction around the arc-shaped waist groove 4. At least two bolts 5 are passed through the housing 312. The bolts 5 pass through the arc-shaped waist groove 4 and extend into the assembly groove 3112. A locking nut 6 is screwed at one end of the bolt 5 located in the assembly groove 3112. During installation, by tightening or unscrewing the locking nut 6, the position of the sliding oil cylinder 313 can be fixed or adjusted. The arc-shaped waist groove 4 is used to adjust the inclination angle of the piston rod of the sliding oil cylinder 313. The angle indicating scale lines 7 can facilitate the installer to install the sliding oil cylinder 313 to the required angle more quickly according to the installation requirements to obtain a better deceleration effect, and at the same time, the consistency of the installation angles of multiple sliding oil cylinders 313 on the mounting frame 311 can be ensured.

[0028] Refer to Figure 4 and Figure 5 As shown in FIGS. 5 and 6, the magnetic induction deceleration mechanism 32 includes a magnetic induction frame 321, an excitation coil 322 and an electromagnet core 323. The electromagnet core 323 is installed on one side of the magnetic induction frame 321 facing the hanging rail 2. The electromagnet core 323 is in a "U" shape or an "E" shape. The plane side of the electromagnet core 323 faces the hanging rail 2, and the opening side extends into the magnetic induction frame 321. In this embodiment, the electromagnet core 323 is preferably in an "E" shape. The excitation coil 322 is installed in the magnetic induction frame 321 and wound around the middle column of the electromagnet core 323. The excitation coil 322 is electrically connected to the regenerative braking energy storage power supply assembly 10. The second driving member 16 is installed between the magnetic induction frame 321 and the side wall of the bogie 11.

[0029] Furthermore, the driving component 16 is a driving electric cylinder, and at least two driving components 16 are arranged at intervals. When slipping occurs, the speed sensor 8 transmits an overspeed signal to the driving component 16, and the driving component 16 drives the magnetic frame 321 to move toward the direction close to the hanging rail 2. At the same time, the regenerative braking energy storage power supply component 10 supplies power to the excitation coil 322, and the excitation coil 322 generates a magnetic field on the electromagnet core 323, making the electromagnet core 323 magnetic, and then uses the attraction between the electromagnet core 323 and the steel hanging rail 2 to generate a large friction force, so that the monorail crane 1 slows down.

[0030] Furthermore, a distance sensor 9 is embedded in the side of the magnetic frame 321 facing the hanging rail 2, and the distance sensor 9 is connected to the signal of the driving component 16. The distance sensor 9 can detect the distance between the magnetic frame 321 and the side wall of the hanging rail 2 in real time, and then the driving component 16 drives the magnetic frame 321 and the electromagnet core 323 to move to the most suitable spacing position to ensure the best deceleration effect.

[0031] Reference Figure 1 and Figure 4 A monorail crane system with multiple deceleration functions also includes a regenerative braking energy storage power supply component 10, which is installed on the cab and electrically connected to the magnetic induction deceleration mechanism 32 and the driving member 16, and is used to convert the braking energy of the monorail crane 1 into electrical energy and store it and provide it to the magnetic induction deceleration mechanism 32 and the driving member 16 for the electrical energy required for operation. The regenerative braking energy storage power supply component 10 is connected to the speed sensor 8 signal.

[0032] The regenerative braking energy storage power supply assembly 10 includes a power supply box 101, a converter 102, an energy storage device 103, a generator 104 and an inertia impeller 105. The power supply box 101 and the generator 104 are both mounted on the side wall of the cab. The inertia impeller 105 is sleeved and fixed on the rotating shaft of the generator 104. The converter 102 and the energy storage device 103 are both mounted in the power supply box 101. The converter 102 is electrically connected to the generator 104 and the energy storage device 103 respectively to convert the mechanical energy of the rotation of the inertia impeller 105 into energy that can be stored by the energy storage device 103. DC power, an electrical interface 13 for connecting the magnetic induction reduction mechanism 32, the driving member 15 and the driving member 2 16 is installed on the outer wall of the power supply box 101, and the electrical interface 13 is electrically connected to the energy storage device 103. The energy storage device 103 includes but is not limited to a lithium-ion battery or a nickel-hydrogen battery. A charging interface 14 electrically connected to the energy storage device 103 is installed on the outer wall of the power supply box 101. In this embodiment, the energy storage device 103 is preferably a lithium battery. The application of the generator 104, the converter 102, and the energy storage device 103 are all existing technologies and will not be described in detail.

[0033] The energy storage device 103 is equipped with a charging interface 14 to ensure that the energy storage device 103 can have the power for initial use. When the deceleration device 3 is decelerating, the primary deceleration mechanism 31 and the magnetic induction deceleration mechanism 32 decelerate the monorail crane 1, so that the monorail crane 1 obtains the inertia force of deceleration braking, and the inertia impeller 105 on the main shaft of the generator 104 can be rotated by the inertia force obtained on the monorail crane 1, thereby realizing the power generation of the generator 104. The converter 102 converts the alternating current generated by the generator 104 into direct current and stores it in the energy storage device 103, thereby ensuring that the energy storage device 103 has the required amount of power for the next deceleration operation of the magnetic induction deceleration mechanism 32 without the need for recharging, and can ensure the stable operation of the magnetic induction deceleration mechanism 32 in the case of power failure, further improving the safety of the deceleration device 3, and providing a guarantee for the safety of life and property of the monorail crane 1 during operation, and also having the effect of energy saving and environmental protection.

[0034] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
