Description

Technical Field

[0001] The present invention belongs to the field of transportation equipment, and particularly relates to a horizontally transporting device for plant equipment that can be adjusted in height and length, which is used for horizontally transporting equipment, large-diameter pipelines, equipment components (heat exchanger tube bundles), and steel structures. It can transport equipment with a foundation higher than the ground or equipment with inoperable conditions for horizontal transportation on the ground in the plant (due to a large number of equipment foundations) from outside the plant to inside the plant for installation, or transport equipment from inside the plant to outside the plant for maintenance and repair. Background Art

[0002] According to the requirements of the production process, many large-scale equipment, large-diameter pipelines, etc. are designed in chemical, petroleum, fertilizer, pharmaceutical and other plants. However, there are many columns and equipment in the plant, and the equipment foundations are all higher than the ground, making it difficult for cranes to enter, which causes great difficulties for the installation of equipment entering the plant or the maintenance and repair of equipment being transported out of the plant.

[0003] Traditional methods use manual hydraulic forklifts for horizontal transportation or install temporary monorail cranes for horizontal transportation. When using a manual forklift to transport equipment, the equipment is likely to roll during the walking process, posing a great safety hazard. In addition, manual hydraulic forklifts are generally used for horizontal transportation, but horizontal transportation occupies a large space and cannot be carried out horizontally in the plant. When using a temporary monorail crane for hoisting, it will damage the floor surface and it is difficult to transport the equipment to the designated position.

[0004] Therefore, how to smoothly, safely and economically transport large-scale equipment, large-diameter pipelines, equipment components (heat exchanger tube bundles) from outside the plant to inside the plant for installation, or transport equipment from inside the plant to outside the plant for maintenance and repair has become a technical problem. Summary of the Invention

[0005] The purpose of the present invention is to provide a horizontally transporting device for plant equipment that can be adjusted in height and length to solve the above problems. It belongs to a horizontal transportation tool for equipment, large-diameter pipelines, equipment components (heat exchanger tube bundles), and steel structures. It can transport equipment with a foundation higher than the ground or equipment with inoperable conditions for horizontal transportation on the ground in the plant (due to a large number of equipment foundations) from outside the plant to inside the plant for installation, or transport equipment from inside the plant to outside the plant for maintenance and repair.

[0006] The present invention achieves the above purpose through the following technical solutions:

[0007] A horizontally transporting device for plant equipment that can be adjusted in height and length includes a mobile tooling for carrying the equipment to be installed, a freight car for transporting the equipment to be installed and the mobile tooling, a support device with adjustable length and height, a traction device for driving the mobile tooling to move back and forth between the support device and the freight car, and a jack for driving the equipment to be installed to unload.

[0008] The mobile tooling includes a head towing device, a tail towing device, and a telescopic connection structure connecting the two towing devices.

[0009] The traction device includes a left winch detachably connected to the head dragging device through a left traction rope, and a right winch detachably connected to the tail dragging device through a right traction rope. The left winch is installed on one side of the support device, and the right winch is installed in the freight car body.

[0010] As a further optimized solution of the present invention, the support device includes a plurality of support frames and a height adjustment system arranged at the bottom of the support frames. The plurality of support frames are detachably connected through connecting bolts.

[0011] As a further optimized solution of the present invention, a transition beam is fixedly arranged at the outer end of the support frame close to the freight car body. The transition beam is lapped with the freight car body, and the head dragging device and the tail dragging device travel on the transition beam and the support frame.

[0012] As a further optimized solution of the present invention, both the head dragging device and the tail dragging device include handling small tanks, support seats, and tightening ropes. The support seats are installed on the handling small tanks and are used to carry the equipment to be installed. The tightening ropes are arranged on the support seats and are used to limit the equipment to be installed.

[0013] As a further optimized solution of the present invention, the telescopic connection structure is a multi-stage telescopic rod or an automatic rewinder.

[0014] As a further optimized solution of the present invention, the left traction rope and the right traction rope are respectively clamped with the hook grooves on the head dragging device and the tail dragging device through hooks.

[0015] As a further optimized solution of the present invention, the horizontal in-plant equipment transfer device further includes an intelligent loading and unloading system. The intelligent loading and unloading system includes a remote control terminal, an alarm installed on the mobile tooling, an RFID reader / writer installed on the mobile tooling, a first RFID tag installed on each piece of equipment to be installed, and a second RFID tag installed on the equipment installation foundation corresponding to the equipment to be installed. The RFID reader / writer and the alarm are connected to the remote control terminal through a wireless communication module.

[0016] As a further optimized solution of the present invention, the remote control terminal is connected to the traction device and the jack through a wireless communication module. A four-wheel drive system is arranged at the bottom of the jack, and an intelligent braking system intelligently controlled by the remote control terminal is arranged on the rollers of the handling small tank.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1) The present invention utilizes a freight trolley to transfer the equipment to be installed. By using a winch and a towing rope to tow a mobile tooling loaded with the equipment to be installed to travel on a support device, the equipment to be installed can be transported to a designated position in reverse. Moreover, the support device is modularly arranged, and its length and height can be set according to the position of the equipment to be installed in the factory building, etc. There is no need for complex installation and demolition work, reducing manpower and material resources, lowering economic costs, and being reusable through turnover. It also solves the difficulty that ground transportation is not feasible, and at the same time solves the problem of installing equipment with an installation height higher than the ground;

[0019] 2) By using two winches and a telescopic connection structure connecting two towing devices, the present invention can tow the mobile tooling into the freight trolley after the equipment to be installed is unloaded, facilitating the direct transportation of the next equipment to be installed and reducing the burden on the staff for recovering the mobile tooling;

[0020] 3) Through the setting of the intelligent loading and unloading system, the present invention can realize the intelligent sequential transportation of multiple equipment to be installed on an installation line, reducing the number of staff, greatly improving the transportation efficiency, avoiding the high-intensity work of continuously disassembling and assembling the support device during the transportation of multiple equipment to be installed, and also avoiding the problems of rework and low efficiency caused by incorrect transportation positions of the equipment to be installed;

[0021] 4) The present invention is directly connected to the freight trolley, saving the crane shift cost for equipment unloading. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Embodiment 1

[0030] As Figures 1-3 shown, an adjustable horizontal transfer device for plant equipment for height increase includes a mobile tooling 2 for carrying the equipment 1 to be installed, a freight car 3 for transporting the equipment 1 to be installed and the mobile tooling 2, a support device 8 with adjustable length and height, a traction device 4 for driving the mobile tooling 2 to move back and forth between the support device 8 and the freight car 3, and a jack 5 for driving the equipment 1 to be installed to unload.

[0031] The support device 8 includes a plurality of support frames 81 and a height adjustment system 82 arranged at the bottom of the support frames 81. The plurality of support frames 81 are detachably connected by connecting bolts. Each support frame 81 includes a longitudinal beam and a cross beam, both of which are made of H-shaped steel. The longitudinal beam and the cross beam, and between the longitudinal and cross beams and the support columns are connected by connecting bolts. This connection method is convenient for on-site installation, disassembly, transfer and storage;

[0032] The number of the support frames 81 is determined according to the installation position of the equipment 1 to be installed. During installation, it extends from the equipment installation foundation of the equipment 1 to be installed at the innermost side of the plant to the outside of the plant.

[0033] The height adjustment system 82 includes a pump station, a pressure guiding pipe and a hydraulic leg;

[0034] The pump station adopts a specification of 1.5KW (380V) bidirectional electromagnetic 4-way and is installed on the support frame 81. One set of pump station drives 4 hydraulic legs;

[0035] The pressure guide pipe uses M20*1.5 external thread to M20*1.5 internal thread, with a pressure of 0 - 50 Mpa, a total of 8 pieces, grouped in sets of 2. One end of each pipe is respectively connected to the inlet or outlet of the hydraulic leg, and the other end is respectively connected to the inlet or outlet of the pump station;

[0036] The hydraulic legs are installed under the support columns, and the hydraulic legs and the support columns are connected together by connecting bolts.

[0037] The mobile tooling 2 includes a head towing device 21, a tail towing device 22, and a telescopic connection structure 23 connecting the two towing devices; both the head towing device 21 and the tail towing device 22 include handling trolleys 221, support seats 222, and tightening ropes 223. The support seats 222 are installed on the handling trolleys 221 and are used to carry the equipment to be installed 1. The tightening ropes 223 are arranged on the support seats 222 and are used to limit the equipment to be installed 1. The telescopic connection structure 23 is a multi-stage telescopic rod or an automatic retractor, which is convenient to adjust the distance between the two towing devices according to the length of the equipment to be installed 1. When the mobile tooling 2 is towed by a single-side towing rope, the entire mobile tooling 2 can be driven to move.

[0038] A transition beam 6 is fixedly arranged at the outer end of the support frame 81 on the side close to the freight car 3. The transition beam 6 overlaps with the freight car 3, and the head towing device 21 and the tail towing device 22 travel on the transition beam 6 and the support frame 81.

[0039] The towing device 4 includes a left winch 42 detachably connected to the head towing device 21 through a left towing rope 41, and a right winch 44 detachably connected to the tail towing device 22 through a right towing rope 43. The left winch 42 is installed on one side of the support device 8, and the right winch 44 is installed inside the freight car 3. The left towing rope 41 and the right towing rope 43 are respectively clamped to the hook grooves on the head towing device 21 and the tail towing device 22 through hooks.

[0040] It should be noted that the equipment to be installed 1 is transported from the construction unit's warehouse to the outside of the factory building where it needs to be installed by using the freight car 3; specifically:

[0041] Before the equipment to be installed 1 is loaded onto the vehicle, the head towing device 21 and the tail towing device 22 are placed inside the freight car 3 and connected to the right winch 44 through the right towing rope 43. At this time, the equipment to be installed 1 can be placed on the head towing device 21 and the tail towing device 22, and after being firmly tied at both ends with the tightening ropes 223, it is transported to the installation site;

[0042] After arriving at the site, connect the hook at one end of the left towing rope 41 to the head towing device 21, then start the left winch 42. The left winch 42 drives the entire mobile tooling 2 and the equipment to be installed 1 to slowly move from the transition beam 6 to the support device 8 through the left towing rope 41, and then move above the corresponding equipment installation foundation 9. At this time, stop the operation of the left winch 42, remove the tightening rope 223, start the two jacks 5 to lift the equipment to be installed 1, so that the equipment to be installed 1 is separated from the support frame 81 by 50 mm. Finally, start the right winch 44, and the right winch 44 drives the entire mobile tooling 2 and the left towing rope 41 to move to the right through the right towing rope 43 until the mobile tooling 2 moves into the freight car 3, completing the horizontal transportation of one equipment to be installed 1;

[0043] Repeat the above operations, from the inside to the outside of the workshop, transport the equipment to be installed 1 on an installation line in place. Finally, release the pressure of the jacks 5, and the equipment to be installed 1 slowly falls on the equipment installation foundation 9, then the positioning of the equipment to be installed 1 can be completed. During this process, multiple pairs of jacks 5 are required.

[0044] During this process, after one equipment to be installed 1 is transported in place, the support device 8 can also be removed, the pressure can be released after installation, and then the support device 8 can be assembled to carry out the transportation and positioning work of the next equipment to be installed 1. The efficiency is slower than the above method, but only one pair of jacks 5 can be used.

[0045] When installing the equipment to be installed 1, if the number of equipment to be installed 1 is large and the floor area of the workshop is too large, then a large number of staff are required to operate during the entire transportation and positioning process, and there is also a problem that the distance between the staff is too far, resulting in untimely information communication between each other, which in turn affects the transportation and positioning efficiency; for this reason, the horizontal transfer device for workshop equipment also includes an intelligent loading and unloading system 7;

[0046] As Figures 1-4 shown, the intelligent loading and unloading system 7 includes a remote control terminal 71, an alarm 72 installed on the mobile tooling 2, an RFID reader / writer 73 installed on the mobile tooling 2, a first RFID tag 74 installed on each equipment to be installed 1, and a second RFID tag 75 installed on the equipment installation foundation 9 corresponding to the equipment to be installed 1. The RFID reader / writer 73 and the alarm 72 are connected to the remote control terminal 71 through a wireless communication module. The remote control terminal 71 can be a mobile phone, a computer or a remote control, etc.

[0047] The remote control terminal 71 is connected to the towing device 4 and the jacks 5 through a wireless communication module. The bottom of the jacks 5 is provided with a four-wheel drive system, and the rollers of the handling small tank 221 are provided with an intelligent braking system intelligently controlled by the remote control terminal 71.

[0048] It should be noted that during the entire transportation process, since only the mobile tooling 2 is involved in the entire process of loading, transferring, and unloading the equipment to be installed 1, we set an RFID reader / writer 73 at the top and bottom of the mobile tooling 2 respectively, and set RFID tags on each equipment to be installed 1 and the equipment installation foundation 9. The RFID reader / writer 73 is used to read and identify the RFID tags to ensure the orderly loading sequence of the equipment to be installed 1 and to be accurately corresponding to the equipment installation foundation 9 during unloading, avoiding the situation where the loading sequence is disordered, resulting in the inability to load all the equipment on an installation line in sequence and misloading. Specifically:

[0049] First, the staff sorts out a label database in a certain order according to the installation sequence of each equipment to be installed 1 from the inside to the outside on an installation line. The label database stores multiple RFID tags arranged in a certain order;

[0050] When the freight trolley 3 drives the mobile tooling 2 to the placement station of the equipment to be installed 1, the staff carries out the handling according to the installation sequence of each equipment to be installed 1. When the equipment to be installed 1 is carried onto the mobile tooling 2, the RFID reader / writer 73 on the top of the mobile tooling 2 identifies the first RFID tag 74 on the equipment to be installed 1 and verifies and compares it with the first RFID tag in the label database. The verification information is sent to the remote control terminal 71. Whether the verification passes or not, the remote control terminal 71 controls the alarm 72 to prompt the staff to carry or replace the equipment to be installed 1 with sound and light signals in different states;

[0051] When the equipment to be installed 1 that has passed the verification is carried onto the mobile tooling 2 and transported to one side of the support device 8 by the freight trolley 3, the traction device 4 is started to drive the mobile tooling 2 and the equipment to be installed 1 to move slowly on the support device 8. During the movement, the RFID reader / writer 73 at the bottom of the mobile tooling 2 continuously identifies the second RFID tag 75 on the equipment installation foundation 9 below until the read second RFID tag 75 is consistent with the first RFID tag in the label database. Then the verification passed information is sent to the remote control terminal 71, and the remote control terminal 71 controls the left winch 42 to stop working, controls the intelligent braking system of the handling trolley 221 to brake, and controls the jack 5 to move under the equipment to be installed 1 and jack up the equipment to be installed 1.

[0052] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
