Description

Technical Field

[0001] The invention relates to the field of large-scale mechanical equipment relocation, in particular to the relocation of large-scale tobacco equipment in the tobacco industry, and in particular to a large-scale equipment transporting method and equipment. Background Art

[0002] The relocation of large equipment is very troublesome. For example, in the equipment manufacturing industry, such as the machine tool industry, large transport vehicles, cranes or large cranes are required to complete the transfer and relocation of large equipment. For specialized industrial and mining equipment manufacturing companies, the transfer and relocation of equipment already has its supporting facilities, which are incorporated into the company's work standards or process standards. Therefore, there are no technical difficulties in the relocation. However, in the tobacco industry, especially cigarette manufacturers, the relocation of large equipment is common, mainly due to adjustments in factory production operations or process line layouts, and cigarette manufacturers generally do not have large transport vehicles or large cranes, and cranes are not installed inside the workshop. Therefore, the relocation of large-scale packaging equipment within the workshop and between two factory buildings is relatively difficult, such as GDH1000-C800 packaging machine, GDX2000-C600 packaging machine, PROTOS 2-2 cigarette making machine units, etc. This is mainly because: first, due to the large size of the equipment, weighing more than ten tons, complex structure, and many connected parts and components, the relocation project cannot be completed by manpower alone, and due to the height limit of the factory building, large cranes cannot be used. There are many equipment in the factory building, but the space is small, and there is no supporting crane. Second, if the relocation is for a complete set of equipment that has been assembled and debugged, if it is disassembled and relocated, the installation cost will be greater, the disassembly and debugging cycle will be longer, and the labor intensity of the workers will be greater. Therefore, the method of disassembly and disassembly cannot be used for relocation; third, since these equipment contain certain precision devices, the entire relocation process requires technical requirements such as small vibration and small tilt angle. Therefore, the overall relocation safety requirements are very high. Based on the handling of large tobacco equipment, especially the relocation of cigarette enterprises' packaging equipment, the technical requirements are very high and the difficulty is also very great.

[0003] In summary, in order to solve the problem of transporting large tobacco equipment, especially the relocation of cigarette packaging equipment in cigarette companies, it is very important to study its transportation methods.

[0044] like Figure 4 The left frame 5 and the right frame 9 have exactly the same structure, and are mainly composed of a frame body 19 and an air cushion system; the frame body 19 is welded from square steel pipes and steel plates, and presents an inverted trapezoidal structure in which the upper base is longer than the lower base, with a length of 4870mm, a width of 720mm, and a height of 646mm; the frame body 19 includes five parts in the length direction, and the front and rear end parts are the installation areas of the guide wheel unit 10, which are used to carry and lift the load and control the running direction of the vehicle body; the middle part is the installation area of ​​the motor drive unit 4, and the two parts between the first two are the installation areas of the supporting fixing device 6 respectively; 6 protective pads 5-1 are welded at the bottom of the frame body 19, and air cushions are installed between the protective pads 5-1, which play a role in supporting and protecting the air cushions when the frame lands.

[0045] like Figure 5 The motor drive unit 4 is installed in the middle of the frame body 19, and mainly consists of a motor 4-8, a driving wheel 4-7, an air spring 4-2 and a motor control system 4-12. The motor drive unit 4 is connected to the frame body 19 by a mounting plate 4-1. Under the action of the air spring 4-2, the driving wheel 4-7 is pressed down to the ground with the twist shaft 4-10 as the rotation center. Driven by the motor 4-8, the vehicle body can be driven to move forward or backward, and the relative steering between the two motors 4-8 can be controlled to realize the clockwise or counterclockwise rotation of the vehicle body in situ. The motor control system 4-12 is composed of three pneumatic components, a reversing valve, and a distributor, and mainly has functions such as filtering and drainage, lubrication and oil supply, motor forward and reverse control, and pressure regulation.

[0046] like Figure 6The guide wheel unit 10 is installed at both ends of the frame body 19 and below the steering rod 7, and mainly consists of a slewing support body 10-1, a bag air spring 10-2, a lower pressure body 10-3, a follower wheel 10-5, a direction control socket 10-6, and a tension spring 10-7; the slewing support body 10-1 of the guide wheel unit 10 is connected to the frame body 19, and each guide wheel unit 10 has two freely rotatable follower wheels 10-5 installed on the lower pressure body 10-3, and the lower pressure body 10-3 can Under the action of the rotating support body 10-1, it rotates 360 degrees in the horizontal plane; between the rotating support body 10-1 and the lower pressure body 10-3 is a bag-type air spring 10-2, which completes the downward pressure and lifting of the follower wheel 10-5, and its control valve is on the upper surface of the frame body 19; in order to better control the walking direction of the vehicle body, the direction of the vehicle body needs to be manually controlled when it is walking and turning. The method is to insert a steering rod into the steering rod socket 10-6 and manually control it according to the actual required rotation angle.

[0047] like Figure 4 The air cushion system is installed at the bottom of the frame body 19, and mainly consists of 2 large load-bearing air cushions 5-3, 4 small load-bearing air cushions 5-2, and 6 protective pads 5-1. The 2 large load-bearing air cushions 5-3 are symmetrically distributed at both ends of the bottom of the vehicle body, and the 4 small load-bearing air cushions 5-2 are symmetrically distributed on both sides of the motor 4-8. Each air cushion is controlled by a pressure control valve, which is installed on the air cavity of the frame body 19, and a pressure gauge is installed at the outlet of the valve to display the air cushion pressure; the 6 protective pads 5-1 are distributed on both sides of the air cushion to protect the air cushion from damage.

[0048] like Figure 7 The connecting frame 2 includes a connecting frame body 20, on which a steering rod 7, a control box 1, a frame connecting pressure plate 3, and a universal wheel 14 are provided. The connecting frame body 20 is welded by square steel pipes and steel plates and has a T-shaped structure. There are two frame connecting pressure plates 3 at both ends of the vehicle body, and a guide wheel unit 10 is provided in the lower middle part. The guide wheel unit 10 is connected to the bottom of the steering rod 7 through a connecting shaft 13. The control box 1 is installed at the head end of the steering rod 7, and four universal wheels 14 are installed around the guide wheel unit 10 at the bottom of the connecting frame body 20.

[0049] like Figure 8The control system mainly includes a control box 1, a main air delivery pipe, a sub-air chamber, a control valve, a connecting pipeline, etc. The main air delivery pipe delivers compressed air to the sub-air chamber 8, and then supplies it to various pneumatic components of the vehicle body. There is a sub-air chamber 8 on the upper surface of the frame body 19, and a hose connects the two sub-air chambers 8; each sub-air chamber has 9 outputs, two for the air supply of large load-bearing air cushions 5-3, one for the air supply of small air cushions 5-2, one for the air supply of air springs 4-2, one for the air supply of the control box 1, two for the air supply of weight-lifting air bags 17, and two for the air supply of bag-type air springs 10-2.

[0050] like Fig. 9 The control box 1 is used to control the operation of the vehicle body, and is mainly composed of a control panel 1-1, a motor drive control valve 1-2, and a handle 1-3. The control panel 1-1 has functions such as air source switch control, guide wheel unit 10 lifting control, drive wheel 4-7 down force control, and vehicle body operation mode control. The motor drive control valve 1-2 is used to control the forward and reverse operation of the motor 4-8.

[0051] like Fig. 9 There are two motor drive control valves 1-2, which control the direction of motor rotation by changing the direction of compressed air entering the motor. One controls the motor to rotate forward and the other controls reverse. The greater the downward pressure on the control valve handle, the greater the working pressure of the motor, the faster the vehicle body moves forward or backward, or the faster the vehicle body rotates counterclockwise or clockwise.

[0052] By controlling the forward and reverse rotation of the two motors, the vehicle body can have two modes: "straight travel" and "rotation". If the two motors rotate forward or reverse at the same time, the vehicle body moves forward or backward; if one rotates forward and the other reverses, the vehicle body rotates.

[0053] The further technology of this embodiment is as follows:

[0054] According to the actual situation and layout of the cigarette factory workshop, the maximum width of the combined wheeled air-cushion vehicle is designed to be 3680mm and the maximum length is 5730mm.

[0055] The left frame 5 and the right frame 9 are inverted trapezoidal structures with a designed length of 4860 mm, a width of 720 mm and a height of 646 mm. The vehicle body is divided into five sections in the length direction. The front and rear ends are for installing the guide wheel unit 10, which is 800 mm long. The middle section is the motor drive unit 4 installation section, which is 1000 mm long. The two sections between the first two are the support and fixing device 6 installation sections, and each section is 1130 mm long.

[0056] The motor drive unit 4 is installed in the middle of the frame body 19. The working pressure of motors 4-8 is 4-7 bar. The air consumption of each drive motor at 90 psi is 1.76 m3 / min, two units total 3.52m 3 / min. The higher the air source pressure, the greater the motor output and the stronger the climbing ability.

[0057] The air cushion system is installed at the bottom of the frame body 19, and mainly consists of 2 K21NHD large load-bearing air cushions, 4 K8NHD small load-bearing air cushions, and 6 protective pads 5-1. The 2 K21NHD air cushions are symmetrically distributed at both ends of the bottom of the vehicle body, and the 4 K8NHD air cushions are symmetrically distributed around the motor system. Each 21NHD air cushion is controlled by a UR06 pressure control valve. The control valve is installed on the air chamber of the frame body 19, and a pressure gauge is installed at the outlet of the valve to display the air cushion pressure. When the left frame 5, the right frame 9 and the connecting frame 2 are connected as a whole, the entire vehicle body can be lifted and moved by the 21NHD air cushion. At this time, it can be pushed by manpower or driven by the motor drive unit 4 equipped with the vehicle body itself. When the left frame 5, the right frame 9 and the connecting frame 2 are not connected as a whole, if the left or right frame 9 is to be moved separately, it is necessary to use the four 8NHD air cushions on each frame. The 8NHD air cushions are grouped in pairs, with one group at the front and one group at the rear of the frame. Each group is controlled by an R200 pressure control valve, which is installed on the air chamber of the frame body 19. There is a ball valve controlling the total switch of the two R200 pressure valves. A pressure gauge is also installed at the outlet of the valve to display the air cushion pressure.

[0058] In the gas circuit system, the main gas pipe of the gas source can be connected to any of the sub-gas chambers. The diameter of the main gas pipe is not less than 1.5 inches, but the two sub-gas chambers need to be connected by a gas pipe with an inner diameter of not less than 20mm (or G3 / 4").

[0059] Finally, there are many different handling solutions depending on the load to be transported. The following is an explanation based on the actual handling situation of the GDX2000 packaging machine: Figure 11-16 shown.

[0060] Step 1, such as Fig.11 As shown, two rows of support rods 6-1 are arranged under the wrapping device 15 according to the actual situation, and SLK-21 / 11 lifting airbags 17 are placed at both ends below each row of support rods 6-1. Auxiliary supports 16 can be installed according to the different wrapping devices 15; then the control air path of the lifting airbag 17 is connected, and the lifting airbag 17 is slowly inflated to lift the load steadily until the height at which the prepared hard square wood block 18 can be placed is reached, as shown in FIG. Fig.12 .

[0061] Step 2, such as Fig.12As shown, the prepared hard square wood block 18 is placed on the supporting point below the wrapping device 15, and then the gas in the lifting airbag 17 is slowly released to make the load fall slowly and steadily on the hard square wood block 18.

[0062] Step 3, such as Fig.13 As shown, the two rows of support rods 6 - 1 and the lifting airbags 17 are removed.

[0063] Step 4, such as Fig.14 As shown, the assembled combined wheeled air-cushion vehicle body is moved to a suitable position around the device 15 so that the center of gravity of the vehicle body is basically located in the middle of the space inside the frame body 19.

[0064] Step 5, such as Fig.14 As shown, the support rod 6 - 1 is rearranged according to the space at the bottom of the frame body 19 and the wrapping device 15 .

[0065] Step 6, such as Fig.15 As shown, the bag air spring 10-2 control valve on the guide wheel unit 10 on the upper surface of the four corners of the vehicle body is operated, as shown in FIG. Figure 6 , slowly inject compressed air into the bag-type air spring 10-2 of the guide wheel unit 10, so that the guide wheel units 10 at the four corners of the vehicle body are slowly pressed to the ground. At this time, the wrapping device 15 will be separated from the hard square wood block 18 under the lifting of the vehicle body and the support rod 6-1, as shown in FIG. Fig.16 .

[0066] Step 7, such as Figure 1 and 5 , press the driving wheel 4-7 to the ground, control the vehicle body to slowly move backward through the driving wheel 4-7, and remove all the hard square wood blocks 18, such as Fig.15 and Fig.16 At this time, the device 15 can be moved over a long distance. During the movement, the guide wheel unit 10 supporting the frame body 19 can be converted into an air cushion supporting the frame body 19 according to actual conditions.

[0067] In addition, a diesel air compressor can be used to supply compressed air, and external forces such as forklifts can be used for outdoor road movement.

[0068] The present invention is easy to use, and has been shown in practical use to realize the overall relocation and movement of large-scale wrapping equipment in the field of tobacco industry wrapping equipment relocation, and to be able to move in a factory building and on outdoor roads. During the relocation process, the equipment is subjected to less bumps and impacts, which effectively protects the accuracy and performance of the equipment, greatly reduces the amount of equipment disassembly and assembly engineering, reduces the damage to the equipment during disassembly and assembly and movement, shortens the time for equipment installation and commissioning, and reduces the labor intensity of workers.

[0069] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
