Description

Technical Field

[0001] The utility model belongs to the technical field of freight unloading equipment, and in particular relates to an array type ultrasonic defreezing device for open wagons. Background Art

[0002] In dry winter conditions, train transport typically sprays water on the roofs of train cars to suppress dust and prevent floating pollution during freight transport. Therefore, the moisture contained in bulk materials transported by open wagons is intended to prevent dust from being sprayed during transportation. However, in cold, high-latitude regions, the bulk materials can freeze together with the cars, making them ineffective for unloading. Existing unloading equipment is unable to complete the unloading process. Unloading requires thawing in a greenhouse, which is time-consuming. Using excavators or breakers to crush the materials for unloading can easily damage the cars, and the resulting crushed materials have large particle sizes, making loading and unloading difficult.

[0003] Therefore, how to provide an array-type ultrasonic defrosting device for open cars is a problem that those skilled in the art urgently need to solve. Utility Model Content

[0004] In view of this, the utility model provides an array type ultrasonic defrosting device for open wagons, which can defrost frozen materials on the side walls and corners of the wagon without damaging the wagon, so as to facilitate subsequent unloading.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: an array type ultrasonic defreezing device for open cars, comprising:

[0006] A turntable, which is used to connect to the lifting mechanism on the car cleaning machine or the car unloading machine;

[0007] An articulated arm, one end of which is fixedly connected to the turntable;

[0008] a swing rod, the swing rod being rotatably connected to the other end of the articulated arm;

[0009] The working end is fixed on the swing rod and is composed of a plurality of groups of defreezing heads arranged in an array. The defreezing heads are connected to a transducer and are connected to an external power supply through the transducer.

[0010] The beneficial effects of the present invention are: the device is connected to a mobile device such as a car cleaning machine or a car unloading machine through a turntable, and the working height of the device can be adjusted by using the lifting mechanism on the external device, which is convenient for work. A joint arm is provided to expand the working area of ​​the working end, which makes it convenient to extend the working end to any position in the car to complete the defrosting work, and the defrosting head on the working end is used to defrost the material. In fact, vibration is used to defrost the material and the car. This method will not damage the car, the crushing particle size is small, and it is also convenient for the subsequent unloading process.

[0011] Preferably, the articulated arm includes a connecting section and an executing section, the connecting section corresponds to one end of the articulated arm, the connecting section is fixedly connected to the turntable, the executing section corresponds to the other end of the articulated arm, the end of the executing section close to the connecting section is rotatably connected to the bearing, the end of the executing section away from the connecting section is movably connected to the swing rod, an electric cylinder is hinged on the connecting section, the telescopic end of the electric cylinder is hinged on the executing section and drives the executing section to swing through the electric cylinder.

[0012] The resulting technical effect is: the articulated arm is realized through a connecting section and an execution section. It can be understood that the execution section is connected to the connecting section through bearing rotation, and the specific drive is achieved through an electric cylinder, which can then adjust the working range of the working end to complete the defrosting work at the specified position.

[0013] Preferably, the swing arm is movably connected to the other end of the articulated arm through a bearing, and a motor reducer is fixed to the outer side of the articulated arm near the other end. The output end of the motor reducer is connected to the gear transmission on the swing arm and controls the reciprocating swing of the swing arm.

[0014] The resulting technical effect is that the swing rod is movably connected to one end of the articulated arm, which actually improves the flexibility of the working end and allows it to work at multiple angles. The specific drive is achieved using a motor reducer, thereby achieving the effect of the working end swinging relative to the articulated arm.

[0015] Preferably, a mounting plate is provided on the base, a plurality of mounting holes are arranged in an array on the mounting plate, and the transducer and the defreezing head are fixed in groups on the mounting holes.

[0016] The resulting technical effect is that the transducer actually converts electrical energy into mechanical energy, which is then transferred to the defrosting head to complete the defrosting of the material. The array-layout defrosting head has a large working area, which improves the defrosting efficiency.

[0017] Preferably, the defrosting head is a rod-shaped or disc-shaped structure, and the transducer converts electrical energy into mechanical energy and transmits it to the defrosting head.

[0018] The resulting technical effect is that the defreezing head actually transmits the vibration energy of the transducer to complete the defreezing work.

[0019] Preferably, the transducer is fixed on the transducer base, the transducer base is fixedly connected to the mounting plate, a vibration transmission core shaft is fixedly connected to the transducer, the outer side of the vibration transmission core shaft is rotatably connected to a transmission sleeve, the end of the transmission sleeve is fixedly connected to a defrost head, a defrost head rotation drive mechanism is fixed on the mounting plate, and the defrost head rotation drive mechanism is transmission-connected to the transmission sleeve.

[0020] The resulting technical effect is: compared with the above-mentioned scheme, this scheme is a combination of rotation and vibration. The transducer transfers energy to the transmission sleeve through the vibration transmission core shaft, thereby achieving both rotation and vibration effects of the defreezing head at the end of the transmission sleeve, thereby completing the defreezing of the material. The disc-shaped or rod-shaped defreezing head can avoid collision with the carriage and cause damage to the carriage during operation. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Example 1

[0030] See the attached Figures 1 to 5 According to an embodiment of the present invention, an array-type ultrasonic defrosting device for an open car includes:

[0031] Turntable 1 is used to connect to the lifting mechanism on the car cleaning machine or the car unloading machine. Specifically, it is connected to the lifting mechanism through the flange base and finally installed on the mobile equipment such as the car unloading machine or the car cleaning machine;

[0032] An articulated arm 2, one end of which is fixedly connected to the turntable 1;

[0033] A swing rod 3 is rotatably connected to the other end of the articulated arm 2;

[0034] Working end 4 is fixed to swing arm 3 and consists of multiple groups of defrosting heads 41 arranged in an array. These heads are connected to transducers 42 and are connected to an external power source. The transducers convert electrical energy into mechanical energy and transfer it to the defrosting heads to defrost the material. The turntable and articulated arm work together to extend the defrosting heads to any position in the carriage to complete the defrosting operation.

[0035] In other embodiments, the articulated arm 2 includes a connecting section 21 and an executing section 22. Both the connecting section and the executing section are rigid parts. It should be noted that the connecting section is shorter, while the executing section is longer and has a larger working area. The connecting section 21 corresponds to one end of the articulated arm 2, and the connecting section 21 is fixedly connected to the turntable 1. The executing section 22 corresponds to the other end of the articulated arm 2. The end of the executing section 22 close to the connecting section 21 is rotatably connected through a bearing, and the end of the executing section 22 away from the connecting section 21 is movably connected to the swing rod 3. An electric cylinder 5 is hinged on the connecting section 21, and the telescopic end of the electric cylinder 5 is hinged on the executing section 22 and drives the executing section to swing through the electric cylinder.

[0036] In other specific embodiments, the swing arm 3 is movably connected to the other end of the articulated arm 2 through a bearing, and a motor reducer 6 is fixed to the outer side of the articulated arm 2 near the other end. The output end of the motor reducer 6 is connected to the gear transmission on the swing arm 3 and controls the reciprocating swing of the swing arm. This scheme realizes the rotation of the slewing bearing through the motor reducer, thereby realizing the angle adjustment of the swing arm.

[0037] In some other embodiments, a mounting plate 8 is provided on the swing rod 3 , and a plurality of mounting holes are arranged in an array on the mounting plate 8 , and the transducer 42 and the defreezing head 41 are fixed in groups on the mounting holes.

[0038] In some other specific embodiments, the defrosting head 41 is a rod-shaped or disk-shaped structure, and the transducer 42 converts electrical energy into mechanical energy and transmits it to the defrosting head.

[0039] Example 2

[0040] Reference Attachment Figure 6Different from the above embodiment, the defreezing head of this embodiment has both vibration and rotation. At the same time, the disc-shaped defreezing head can prevent the working end from colliding with the carriage and causing damage to the carriage. Specifically, the transducer 42 is fixed on the transducer base 7, and the transducer base 7 is fixedly connected to the mounting plate 8. A vibration transmission core shaft is fixedly connected to the transducer 42, and the outer side of the vibration transmission core shaft is rotatably connected to the transmission sleeve 10. The end of the transmission sleeve 10 is fixedly connected to the defreezing head 41, and a defreezing head rotation drive mechanism 9 is fixed on the mounting plate 8. The defreezing head rotation drive mechanism 9 is transmission-connected to the transmission sleeve 10.

[0041] Compared with existing technologies, this product boasts a wider operating range and safer production. Its arm-mounted defreezing device can reach any corner of the carriage, simultaneously achieving both rotary and vibratory crushing without damaging the carriage; defrosting can be completed without opening the carriage doors. In actual use, the crushed material has a particle size of less than 100mm. Specifically, during operation, the combined action of the various mechanisms brings the array of defreezing heads close to the frozen coal, where the ultrasonic defreezing heads vibrate at a high frequency, shattering the frozen coal. Furthermore, due to the small amplitude, there is no damage to the carriage. While a single defreezing head is inefficient, this product utilizes an array layout to improve defreezing efficiency.

[0042] As for the devices and methods of use disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple, and the relevant parts can be referred to the description of the methods.

[0043] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
