Description

Technical Field

[0001] This invention relates to cargo transport vehicles, and more specifically, to a method of using a direct-lifting car-type transport frame with a lifting cylinder as a guide column. More specifically, it relates to a method of using a direct-lifting car-type transport frame with the cylinder body of the lifting cylinder as a guide column. Background Technology

[0002] With increasingly standardized regulations for heavy-duty transport, the axle load requirements for transport vehicles are becoming more stringent. Previously, bulk cargo weighing over 200 tons was typically transported using a connecting platform method. However, because the number of axles on a vehicle using this method is limited, it resulted in severely excessive axle loads, leading to its prohibition. Carriage-type transport has been adopted as a replacement. To reduce transportation costs and ensure good train maneuverability, the number of axles required for carriage-type transport should be minimized while still meeting axle load limits. Therefore, the carriage itself must be as lightweight as possible.

[0003] To reduce the weight of car-mounted transport racks, many small and medium-sized car-mounted transport racks on the market (with a load capacity of 200-350 tons) are not designed with lifting devices. Car-mounted transport racks are specialized equipment for transporting large, non-detachable goods such as large transformers, and are generally used in conjunction with hydraulic trailers. Because the goods are generally quite tall, and due to the height limitations of bridges and culverts, the ground clearance of the goods loaded on a car-mounted transport rack cannot be very high even when the hydraulic trailer is raised to its maximum height, resulting in poor maneuverability. For example, when entering or exiting curves at highway entrances and exits, the bottom of the goods may collide with the guardrail of that section of the highway. In such cases, it is often necessary to remove the guardrail for that section, further increasing the difficulty of transportation.

[0004] The existing patent number is ZL 2011 2 0130678.3, titled "Direct Lifting Bridge Transport Frame with Guide". It adds a guide device and a hydraulic cylinder. The cylinder body is fixed to the load-bearing beam. The piston rod of the cylinder can extend or shorten, causing the turntable base to move up or down, thereby raising or lowering the load-bearing beam and adjusting the height of the load-bearing beam and the goods, improving its passability. While its lifting cylinder only bears axial force, the piston rod of the lifting cylinder in this direct lifting car-type transport frame bears radial force (in ordinary direct lifting bridge transport frames, the traction force is transmitted through the piston rod of the lifting cylinder, meaning the piston rod bears radial force; when the traction force is large, the radial force on the piston rod is also large, leading to cylinder leakage and low safety). Furthermore, due to the addition of the guide device (including a guide cylinder and a guide rod), its weight is increased compared to ordinary direct lifting car-type transport frames.

[0005] Therefore, it is necessary to develop a method for using a car-type transport frame that has lifting function, prevents oil leakage from the hydraulic cylinder, has high safety, and reduces its own weight. Summary of the Invention

[0006] The purpose of this invention is to provide a method for using a direct-lifting car-type transport frame with a lifting cylinder as the guide column. This method features lifting functionality, prevents cylinder leakage, ensures high safety, and reduces weight. The invention fixes the piston rod of the cylinder, while the cylinder body moves to lift the supporting beam. Furthermore, it eliminates the need for a traditional guide column, directly using the cylinder body as the guide column in the lifting structure. The piston rod is not subjected to radial force, ensuring good sealing of the cylinder even under significant traction and braking forces, preventing oil leakage, improving safety, and greatly reducing weight. This invention solves the problem of conventional direct-lifting car-type transport frames where the piston rod of the lifting cylinder bears radial force, potentially leading to oil leakage and safety accidents during use.

[0007] To achieve the above objectives, the technical solution of the present invention is: a method for using a direct lifting car-type transport frame with a lifting cylinder as a guide column, characterized by comprising the following steps.

[0008] Step 1: Assemble the car-type transport frame to transport the train;

[0009] Connect the front hydraulic trailer to the truck head;

[0010] The front lifting tower of the direct lifting car transport frame, which uses the lifting cylinder body as a guide column, is installed on the front hydraulic trailer, and the rear lifting tower of the direct lifting car transport frame, which uses the lifting cylinder body as a guide column, is installed on the rear hydraulic trailer.

[0011] The direct lifting car-type transport frame with the lifting cylinder body as the guide column is connected to the front lifting tower and the rear lifting tower respectively through the connecting pin of the supporting frame and the lifting tower.

[0012] The goods to be transported are installed on the car-type transport frame.

[0013] Step 2: When the car-type transport train enters or exits the curve of the highway intersection, the front and rear lifting towers are raised or lowered by hydraulic operation, thereby driving the car-type transport frame and the goods to rise or fall together, thus avoiding obstacles and improving the passability of the car-type transport frame and the goods.

[0014] When it is necessary to control the raising or lowering of the front and rear lifting towers, hydraulic operation is used to fill or release oil in the large chambers of the lifting cylinders of the front and rear lifting towers. The cylinder body of the lifting cylinder on the front lifting tower moves up or down, causing the first slewing bearing, the swing beam connecting seat, and the swing beam of the front lifting tower to move up or down. At the same time, the cylinder body of the lifting cylinder on the rear lifting tower moves up or down, causing the second slewing bearing and the fixed beam of the rear lifting tower to move up or down, thereby causing the car-type transport frame and the goods to rise or fall together.

[0033] The crossbeam is located at the end of the longitudinal beam;

[0059] The present invention has the following advantages:

[0060] (1) This invention breaks with the conventional method of fixing the cylinder body and moving the piston rod of the hydraulic cylinder. It is the first to adopt a lifting structure with the cylinder body of the lifting hydraulic cylinder as the guide column. The piston rod is not subject to radial force, which can ensure that the hydraulic cylinder has good sealing performance when the train has a large traction force and braking force, and will not leak oil, thus ensuring safety. It solves the problem that the piston rod of the lifting hydraulic cylinder of the ordinary direct lifting car-type transport frame has to bear radial force (the traction force of the ordinary direct lifting bridge-type transport frame is transmitted through the piston rod of the lifting hydraulic cylinder, that is, the piston rod of the hydraulic cylinder bears radial force. When the traction force is large, the radial force borne by the piston rod of the hydraulic cylinder is also large, which will lead to the problem of hydraulic cylinder leakage).

[0061] (2) The present invention uses the cylinder body of the hydraulic cylinder as the guide column, thereby eliminating the guide column in the prior art. The lifting hydraulic cylinder is installed in the middle, so that only one lifting hydraulic cylinder is needed for the front lifting tower and the rear lifting tower to drive the car-type transport frame to rise or fall, which greatly reduces its weight.

[0062] (3) The present invention uses a three-row roller slewing bearing with small size and large load capacity as the slewing bearing (turntable), so that the structural size above the turntable will be relatively small, which can reduce the weight;

[0063] (4) The present invention has strong applicability and high safety. The present invention is not only applicable to turning sections, but also applicable to roads with large transverse slopes, large slopes or large hump sections. Attached Figure Description

Detailed Implementation

[0076] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, these descriptions do not constitute a limitation of the present invention and are merely illustrative. The advantages of the present invention will become clearer and easier to understand through this description.

[0077] Referring to the attached diagram, the method of using a direct lifting car-type transport frame with a lifting cylinder as the guide column includes the following steps:

[0078] Step 1: Assemble the car-type transport frame to transport the train;

[0079] Connect the front hydraulic trailer 1 to the truck head;

[0080] The front lifting tower 2 of the direct lifting car transport frame, which uses the lifting cylinder body as a guide column, is installed on the front hydraulic trailer 1, and the rear lifting tower 4 of the direct lifting car transport frame, which uses the lifting cylinder body as a guide column, is installed on the rear hydraulic trailer 5.

[0081] The direct lifting car-type transport frame 3, with the cylinder body of the lifting cylinder as the guide column, is connected to the lifting tower platform via the lifting tower platform and the front lifting tower platform 2 and the rear lifting tower platform 4 respectively.

[0082] The goods 11 to be transported are installed in the middle of the car-type transport frame 3;

[0083] The above constitutes the car-type transport frame transport train;

[0084] Step 2: When the car-type transport frame train enters or exits the curve of the highway intersection, the front lifting tower 2 and the rear lifting tower 4 are controlled to rise or fall through hydraulic operation, thereby driving the car-type transport frame 3 and the cargo 11 to rise or fall together, thus avoiding obstacles (such as highway guardrails), which can better improve its passability and enhance the passability of the car-type transport frame 3 and the cargo 11.

[0085] When it is necessary to control the lifting of the front lifting tower 2 and the rear lifting tower 4, the large chambers of the lifting cylinders 8 of the front lifting tower 2 and the rear lifting tower 4 are filled with oil through hydraulic operation. The cylinder body 8.1 of the lifting cylinder on the front lifting tower 2 moves upward, driving the first slewing bearing (turntable) 2.2, the swing beam connecting seat 2.4 and the swing beam 2.3 of the front lifting tower 2 to move upward. At the same time, the cylinder body 8.1 of the lifting cylinder on the rear lifting tower 4 moves upward, driving the second slewing bearing (turntable) 4.2 and the fixed beam 4.5 of the rear lifting tower 4 to move upward, thereby driving the car-type transport frame 3 and the cargo 11 to rise together.

[0086] When it is necessary to control the lifting of the front lifting tower 2 and the rear lifting tower 4, hydraulic operation is used to release oil from the large chambers of the lifting cylinders 8 of the front lifting tower 2 and the rear lifting tower 4. The cylinder body 8.1 of the lifting cylinder on the front lifting tower 2 moves downward, causing the first slewing bearing (turntable) 2.2, the swing beam connecting seat 2.4, and the swing beam 2.3 to move downward. At the same time, the cylinder body 8.1 of the lifting cylinder on the rear lifting tower 4 moves downward, causing the second slewing bearing (turntable) 4.2 and the fixed beam 4.5 to move downward, thereby causing the car-type transport frame 3 and the cargo 11 to descend together (e.g., Figure 11 (As shown).

[0087] This invention can easily achieve the lifting and lowering of the car-type transport frame 3. Since the lifting cylinder body is embedded in the guide seat, the lifting cylinder body will not produce large back-and-forth or left-and-right swaying. At the same time, the lower end of the upper lifting cylinder piston rod is embedded with a radial joint bearing (i.e., the lifting cylinder connecting pin 2.6), allowing the lifting cylinder piston rod to swing back-and-forth and left-and-right at a certain angle. The lifting cylinder piston rod always only bears axial force, thus ensuring that when the front lifting tower 2 and the rear lifting tower 4 are subjected to large horizontal traction or braking force, the lifting cylinder piston rod will not generate additional radial force, thereby ensuring that the lifting cylinder seal is not damaged, thus ensuring that the lifting cylinder will not be damaged or leak oil. In addition, this invention uses the upper lifting cylinder body instead of the guide column, eliminating the need for a conventional guide column and greatly reducing the weight of the lifting tower.

[0088] This invention boasts strong applicability and high safety. It is suitable not only for curved sections but also for roads with significant transverse slopes, steep inclines, or large hump sections. In this invention, the swing beam 2.3 on the front lifting tower 2 is capable of swinging left and right, while the fixed beam 4.5 on the rear lifting tower 4 is immovable. When one end of the rigid car-type transport frame 3 is connected to the swing beam 2.3 and the other end to the fixed beam 4.5, the rigid car-type transport frame 3 becomes a three-point support, with the three points forming a plane. This ensures that even when the car-type transport train operates on roads with significant transverse slopes, the car-type transport frame 3 will not experience additional torsional forces. Figure 3 and Figure 4 It is understood that the car-type transport frame 3 is hinged to the crossbeams on the front and rear lifting towers 2 and 4 respectively via connecting pins 6 between the load-bearing frame and the lifting tower. This allows the car-type transport frame 3 to swing vertically, ensuring that the load-bearing frame 3 does not generate additional force even when the car-type transport train is operating on steep slopes or sections with large humps. Therefore, the car-type transport train described in this invention does not generate additional force under various road conditions, thus ensuring the safety of the direct-lift car-type transport frame and the cargo 11, with the lifting cylinder body serving as a guide column.

[0089] Furthermore, the car-type transport frame transport train includes a car head, a front hydraulic trailer 1, a direct lifting car-type transport frame with the lifting cylinder body as a guide column, and a rear hydraulic trailer 5;

[0091] The lifting cylinder body serves as a guide column, and the two ends of the direct lifting car-type transport frame are connected to the front hydraulic trailer 1 and the rear hydraulic trailer 5, respectively.

[0092] Furthermore, the direct-lift car-type transport frame, with the lifting cylinder body serving as the guide column, includes a front lifting tower 2, a rear lifting tower 4, and a car-type transport frame load-bearing frame 3.

[0093] The front lifting tower 2 is mounted on the front hydraulic trailer 1, and the rear lifting tower 4 is mounted on the rear hydraulic trailer 5.

[0094] The two ends of the car-type transport frame 3 are connected to the lifting tower platform via the connecting pins 6, which are respectively connected to the front lifting tower platform 2 and the rear lifting tower platform 4.

[0095] Guide seats 10 and lifting cylinders 8 are installed on both the front lifting tower 2 and the rear lifting tower 4;

[0096] The lifting cylinder 8 includes a cylinder body 8.1 and a piston rod 8.2. One end of the piston rod 8.2 is located inside the cylinder body 8.1, and the other end is connected to the lower part of the front lifting tower 2 or the rear lifting tower 4.

[0098] Furthermore, the front-end lifting tower 2 includes a front-end load-sharing beam 2.1, a swing beam 2.3, and a swing beam connecting seat 2.4;

[0099] The front-end load-bearing beam 2.1 is located on the front-end hydraulic trailer 1;

[0100] The guide seat 10 is welded to the front-end load-bearing beam 2.1.

[0101] One end of the piston rod 8.2 of the lifting cylinder is connected to the front load-sharing beam 2.1;

[0102] The flange seat at the upper end of the lifting cylinder body 8.1 is connected to the first slewing bearing (turntable) 2.5;

[0103] The swing beam connecting seat 2.4 is installed on the first slewing bearing (turntable) 2.2. The swing beam 2.3 is connected to the swing beam connecting seat 2.4.

[0104] Furthermore, the front-end lifting tower 2 also includes a swing beam connecting pin 2.5 and a lifting cylinder connecting pin 2.6; the swing beam 2.3 is connected to the swing beam connecting seat 2.4 through the swing beam connecting pin 2.5; the lower end of the lifting cylinder piston rod 8.2 is connected to the front-end load-sharing beam 2.1 through the lifting cylinder connecting pin 2.6.

[0105] Furthermore, the car-type transport frame 3 includes a crossbeam 3.1, an end longitudinal beam 3.3, and a middle longitudinal beam 3.5;

[0106] The end longitudinal beam 3.3 is located at both ends of the middle longitudinal beam 3.5;

[0107] The crossbeam 3.1 is located at the end of the longitudinal beam 3.3;

[0108] The horizontal beam 3.1, the end longitudinal beam 3.3, and the middle longitudinal beam 3.5 are connected in sequence to form an octagonal frame structure.

[0109] Furthermore, the car-type transport frame 3 also includes a connecting pin 3.2 between the crossbeam and the end longitudinal beam, a connecting pin 3.4 between the end longitudinal beam and the intermediate longitudinal beam, and a support rod system 3.6;

[0110] The crossbeam 3.1 is connected to the end longitudinal beam via a connecting pin 3.2, which is connected to the end longitudinal beam 3.3.

[0114] The two ends of the first telescopic support rod 3.61 are respectively hinged to the ends of the two opposite longitudinal beams 3.3;

[0115] The two ends of the second telescopic support rod 3.62 are respectively hinged to the ends of the two opposing intermediate longitudinal beams 3.5;

[0116] The third telescopic support rod 3.63 is located at the connection between the end longitudinal beam 3.3 and the middle longitudinal beam 3.5, and the two ends of the third telescopic support rod 3.63 are respectively hinged to the ends of the end longitudinal beam 3.3 and the middle longitudinal beam 3.5;

[0117] The fourth telescopic support rod 3.64 is hinged at one end to the middle of the crossbeam 3.1 and at the other end to the middle of the end longitudinal beam 3.3. By adjusting the length of each rod in the support rod system 3.6, the internal width of the car-type transport frame 3 can be changed, thus easily meeting the transportation needs of goods of different widths. At the same time, the support rod system 3.6 makes the load-bearing frame spliced ​​by each beam a stable rigid body, thereby ensuring the safety of transportation.

[0118] Furthermore, the rear lifting tower 4 includes a rear load-sharing beam 4.1, a second slewing bearing (turntable) 4.2, and a fixed crossbeam 4.5;

[0119] The lifting function and lifting components of the rear lifting tower 4 are exactly the same as those of the front lifting tower 2; the fixed crossbeam 4.5 of the rear lifting tower 4 replaces the swing crossbeam 2.3, swing crossbeam connecting seat 2.4 and swing crossbeam connecting pin 2.5 of the front lifting tower 2, thereby reducing its weight.

[0120] The rear load-bearing beam 4.1 is located on the rear hydraulic trailer 5;

[0121] The guide seat 10 is welded to the rear load-bearing beam 4.1;

[0122] One end of the piston rod 8.2 of the lifting cylinder 8 is connected to the rear load-sharing beam 4.1;

[0123] The flange seat at the upper end of the lifting cylinder body 8.1 is connected to the second slewing bearing (turntable) 4.2;

[0124] The fixed crossbeam 4.5 is installed on the second slewing bearing (turntable) 4.2;

[0128] Furthermore, the rear lifting tower 4 also includes an automatic following steering device;

[0129] The automatic following steering device includes an automatic following power take-off cylinder mounting base 4.3 and an automatic following power take-off cylinder 4.4;

[0130] The automatic following power take-off cylinder mounting base 4.3 is installed on the anti-rotation base 7;

[0131] The cylinder body of the automatic following power take-off cylinder 4.4 is mounted on the anti-rotation seat 7, and the piston rod is connected to the steering cylinder of the rear hydraulic trailer 5. The function of the automatic following steering device is that when the front hydraulic trailer 1 turns, the car-type transport frame 3 will rotate relative to the rear lifting tower 4. This rotation will cause the automatic following power take-off cylinder 4.4 to compress or extend. Since the automatic following power take-off cylinder 4.4 is connected to the steering cylinder of the rear hydraulic trailer 5, the steering cylinder of the rear hydraulic trailer 5 will be extended or compressed, thereby pushing the rear hydraulic trailer 5 to turn, thus realizing that the rear hydraulic trailer 5 automatically follows the steering of the front hydraulic trailer 1.

[0132] There are multiple automatic follow-up power take-off cylinders 4.4, which are arranged at intervals.

[0133] Both the first slewing bearing (turntable) 2.2 and the second slewing bearing (turntable) 4.2 adopt three-row roller slewing bearings. The three-row roller slewing bearings are small in size and have a large load-bearing capacity, which greatly reduces the weight of the lifting tower.

[0134] All other unspecified parts belong to the prior art.
