Description

Pull formula tie-beam and module transport vechicle

Technical Field

The utility model relates to the technical field of module transport vehicles, in particular to a drawing type connecting beam and a module transport vehicle.

Background

The SPMT modular transporter is a self-propelled flatbed trailer that is modularly produced and assembled and can be configured in a variety of configurations, sizes and weights depending on the different needs of the cargo being loaded. The SPMT module transport vehicle is mainly applied to the transportation of heavy, large, high and special-shaped structures, has the advantages of flexible use, convenient loading and unloading, and the load capacity of more than 50000 tons under the condition of multi-vehicle mechanical assembly or free combination, and is widely applied to the engineering fields of equipment manufacturing industry, petroleum, chemical industry, marine petroleum, bridge construction and the like.

The traction of the SPMT is provided by a hydraulic motor powered by a power head, i.e., PPU, located at the end of the device, which ensures that the SPMT has excellent traction and a compact layout. Each axis of the SPMT executes various actions and realizes various postures, such as moving, rotating, lifting and the like, under the precise control of a main control program, so that the SPMT has good controllability and can complete actions which cannot be completed by a traditional trailer, such as a girder transporting vehicle and the like.

Therefore, when facing cargoes with different weights or sizes, the point arrangement of the SPMT module car has diversified configuration modes, and a plurality of schemes can be implemented, and generally, an optimal scheme is selected, but the optimal scheme is limited in different aspects.

First, size limitations. Due to the size of goods, the transportation requirements can be met by adding the PPUs on the car head to perform grouping or adding the splicing of six-axis or four-axis modular cars. Secondly, mass limitation. Each axis has a respective load capacity parameter and an actual load carrying efficiency parameter, which need to be taken into account during the configuration of the vehicle. The high-mass cargo can be added with PPU and four-axis and six-axis modules to achieve corresponding loading efficiency and rated axle load. The two are possibly limited together, namely, the goods with large size and small mass can be taken into consideration, at the moment, the four-axis and six-axis module car set needs to be added by considering the length of the goods, so that the loading efficiency of the module car set is greatly reduced, and the goods with lighter mass can deviate from the module car under the condition of low loading efficiency, and are not beneficial to transportation.

Another solution is to provide fixed length connecting beams to meet the transportation requirements. For example, utility model patent with publication number CN210653330U provides a module transport vehicle tie-beam device, which comprises a main beam and two end beams, wherein the end beams are detachably connected with the module transport vehicle. The technical scheme can optimize the transportation efficiency of large-size and small-mass goods.

However, the above solutions still have disadvantages, that is, the length of the connecting beam is fixed, so the adaptability is not good, the scheduling of the SPMT module vehicle is also limited, and the utilization efficiency is not high. For example, when loading cargoes with different lengths, the SPMT module and the connecting beam need to be loaded and unloaded back and forth, which is time-consuming and labor-consuming.

Therefore, there is a need for a connecting beam capable of being drawn to connect SPMT modules, and to realize controllable length variation to meet the requirements of different sizes of transported objects, so as to make an optimal transportation scheme.

In this document, "one" means not only "only one" but also a case of "more than one".

It should be further understood that the term "and/or" as used in this specification and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items. In this document, unless expressly stated or limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

The first embodiment is as follows: a drawing type connecting beam.

The drawing type connecting beam of the embodiment is used for hard splicing between SPMT modules, and comprises a drawing type outer beam 1 and a drawing type inner beam 2 as shown in figure 2. As shown in fig. 1, the drawer outer 1 has a slide groove 113 extending in the longitudinal direction; the inner beam 2 is slidably disposed in the sliding groove 113. As shown in fig. 2, the present embodiment further includes a latch assembly 3 composed of a pin shaft 301 and a cotter pin 302 as a coupling member for detachably fixing the drawn outer beam 1 and the drawn inner beam 2. As shown in fig. 4, the drawer outer 1 has a first end provided with a first end plate 105, four second threaded holes 111, two first latch lug plates 110 for connection to an SPMT module. As shown in fig. 5, the inner shell 2 has a second end remote from the first end plate 105 of the outer shell 1, which is provided with a second end plate 205, four third threaded holes 210 and two second bayonet lug plates 209, adapted to be connected to another SPMT module.

The second threaded hole 111, the third threaded hole 210, the first plug-pin lug plate 110 and the second plug-pin lug plate 209 are disposed according to a connection interface of a common SPMT module. As a variation of this embodiment, the connection interfaces may be combined and collocated, for example, the outer drawing beam 1 may be provided with only the second threaded hole 111, and the inner drawing beam 2 may be provided with only the third threaded hole 210; the drawn outer beam 1 may be provided with only the second threaded hole 111 and the drawn inner beam 2 with only the second latch lug 209, while other positions may be used for other purposes. When the connection interface on the SPMT module is specially configured, it is only necessary to match and configure corresponding connection structures at the first end and the second end. The bolt component 3 can also adopt the pin shaft and the spring retainer ring and other forms.

Specifically, as shown in fig. 1 and 4, the drawer outer 1 includes a first flat plate 101, a first side plate 102, a second side plate 103, and a first reinforcement 104, and the first reinforcement 104 has a V-shaped cross section. The first side plate 102 and the second side plate 103 are respectively and fixedly disposed on two sides of the first plate 101 and extend downward, and the first stiffener 104 is connected to the first side plate 102 and the second side plate 103 and encloses with the first plate 101 to form a sliding chute 113. As shown in fig. 5 and 6, the drawer inner 2 includes a second flat plate 201, a third side plate 202, a fourth side plate 203, and a second reinforcement 204. The third side plate 202 and the fourth side plate 203 are respectively fixed on two sides of the second flat plate 201 and extend downwards, the second reinforcement 204 connects the third side plate 202 and the fourth side plate 203 to form a closed cross section, and the cross section of the inner beam 2 is matched with the sliding slot 113, so that the inner beam 2 can smoothly and stably slide in the sliding slot 113.

The arrangement of the first side plate 102, the second side plate 103, the third side plate 202 and the fourth side plate 203 can obviously improve the bending rigidity of the outer drawn beam 1 and the inner drawn beam 2, so that the outer drawn beam is suitable for bearing. The arrangement of the first reinforcing part 104 and the second reinforcing part 204 with the V-shaped cross sections can further improve the bending rigidity of the outer drawn beam 1 and the inner drawn beam 2, so that the thickness of the related structure can be reduced, and the lightweight design is realized. The first end plate 105 and the second end plate 205 are arranged to facilitate the arrangement of the first pin lug 110 and the second pin lug 209, and to form a closed end face, thereby further improving the structural rigidity and strength.

The above-described arrangement is the best mode for the application of the present application to modular transportation of large loads. There may be many variations depending on the application scenario. For example, the drawer outer 1 may be formed in a simple channel shape, the first reinforcement 104 may be provided between the first side plate 102 and the second side plate 103 to form the slide groove 113, and the drawer inner 2 may be formed in a simple structure including only the second plate 201 so as to be slidable in the slide groove 113. At the moment, the shape of the channel steel can be opened downwards, can also be opened upwards, and can also be horizontally arranged. The first side plate 102 and the second side plate 103 may be inclined inward to form a sliding groove 113 with a trapezoidal cross section, and the first stiffener 104 may not be provided. The sliding groove 113 may be formed by a groove formed on the first plate 101, and the inner beam 2 is disposed on the upper end surface of the outer beam 1, and a rib is disposed on the inner beam 2 for slidably disposed in the groove, so that the outer beam 1 needs to be temporarily supported by an auxiliary device such as a hydraulic lift car or a jack or an adjustable height supporting device disposed at the bottom of the outer beam 1 when the length of the connection beam is adjusted, and the outer beam 1 is removed or retracted after the adjustment is completed and the connection is completed. These variations can be used in scenarios where the load is small, but the cargo is long and requires some support over the full length.

As shown in fig. 1 to 4, the first side plate 102 is provided with a plurality of first pin holes 106 at equal intervals, the second side plate 103 is provided with a plurality of second pin holes 107 at equal intervals, the third side plate 202 is provided with a plurality of third pin holes 206 matching with the first pin holes 106, and the fourth side plate 203 is provided with a plurality of fourth pin holes 207 matching with the second pin holes 107. As shown in fig. 2 and 3, when the length of the connection beam needs to be adjusted, the pin 301 needs to be pulled out, and then the pulling outer beam 1 and the pulling inner beam 2 are pulled or pushed to the required positions by the power of the SPMT module; portions of the pins 301 are then inserted back into the corresponding pin holes. In the embodiment, the shortest length of the drawing connecting beam is 8.4 meters calculated according to the length of the upper end surface of the bearing; the first pin hole 106, the second pin hole 107, the third pin hole 206 and the fourth pin hole 207 are all 9, and the distance is 0.84 m. The inner girder 2 of fig. 2 and 3 is pulled out 3.36 m from the outer girder 1, so that the length of the coupling girder is 11.76 m. At this time, there is still a one-to-one correspondence between each 5 pairs of pin holes on both sides, that is, each 5 pins 301 on both sides need to be inserted back into the corresponding pin holes to complete the fixed connection (only one pair of pin 301 and cotter pin 302 is schematically shown in the drawings of the specification). When the bearing requirement is not high, the drawing connecting beam of the embodiment can be stretched to 15.12 meters.

As a variation of this embodiment, the pin 301 may also be disposed between the first plate 101 and the second plate 201. At this time, a step through hole may be formed in the first plate 101, and a matching pin hole may be formed in the second plate 201, so that the outer drawn beam 1 and the inner drawn beam 2 may be connected by the pin 301. At this time, the pin shaft 301 is not easily dropped, and the cotter pin 302 may not be provided. The spacing between the first pin holes 106 and the third pin holes 206 may not be equal, for example, the spacing between the first pin holes 106 may be set to be a multiple of the spacing between the third pin holes 206, which is suitable for the situation where the shear strength provided by a small number of pin shafts 301 is sufficient; the intervals of the first pin holes 106 can also be set without equal intervals, for example, the interval near the first end plate 105 can be set to be larger, and the interval at the other end can be set to be smaller, so that the drawing connecting beam is suitable for occasions needing coarse adjustment only when the length of the drawing connecting beam is shorter and needing fine adjustment after the drawing connecting beam is lengthened; the opposite second pin hole 107 and the fourth pin hole 207 may be provided accordingly.

As shown in fig. 2, the first plate 101 has a first operation hole 108 formed therethrough at a position matching the first pin hole 106, the second pin hole 107, the third pin hole 206, and the fourth pin hole 207. The second plate 201 is provided with a second operation hole 208 matching the first operation hole 108, and the first operation hole 108 and the second operation hole 208 are used for providing a passage for arranging a locking member, namely, a cotter pin 302. Namely, each pin hole is correspondingly provided with one first operating hole 108 or one second operating hole 208, and when the two matched pin holes are aligned in position for inserting the pin shaft 301, the corresponding first operating hole 108 and the corresponding second operating hole 208 are also exactly aligned. As shown in fig. 8, after the pin shaft 301 is inserted into the aligned corresponding pin holes, the tail portion of the pin shaft 301 is located just below the aligned corresponding first and second operation holes 108 and 208, so that the cotter pin 302 can be manually inserted or removed. Likewise, for each second threaded hole 111, the first plate 101 is provided with a third operating hole 109 for facilitating operation when the drawer outer 1 is connected to the SPMT module.

The drawing connection beam further comprises an electrical trunk line and a hydraulic trunk pipe, and the electrical trunk line and the hydraulic trunk pipe are respectively used for electrical connection and hydraulic connection between the two SPMT modules connected to the two ends of the drawing connection beam; the electrical and hydraulic relay lines each include a telescoping portion. Specifically, the hydraulic relay pipe comprises a connector, a hard pipe section and a soft pipe section; the electrical trunk comprises an aviation plug or an aviation socket and a connecting section; the connection section of the electric trunk line and the hose section of the hydraulic trunk pipe are connected in a telescopic mode through folding and hanging or drag chain type arrangement so as to adapt to the states of different lengths of the pull-type connecting beam. Both the electrical and hydraulic relay lines are disposed in cavities below the first and second plates 101, 201, and the first and second end plates 105, 205 are provided with aviation plugs or aviation sockets and interfaces. Electrical and hydraulic relay pipes can also be arranged at the sides of the drawn outer beam 1 and the drawn inner beam 2.

Because first bolt otic placode 110 and second bolt otic placode 209 match the setting with the otic placode bolt interface at SPMT module both ends respectively, and the otic placode bolt interface at SPMT module both ends can be used to the series connection each other of a plurality of SPMT modules, consequently, the pull formula tie-beam of a plurality of embodiments also can loop through the first bolt otic placode 110 of a pull formula tie-beam of bolt connection and the second bolt otic placode 209 of another pull formula tie-beam, and connect gradually the second screw hole 111 of a pull formula tie-beam and the third screw hole 210 of another pull formula tie-beam through stud, thereby splice into longer pull formula tie-beam, provide nimble configuration mode.

The side plate structure and the V-shaped reinforcing piece structure can greatly increase the bending rigidity of the connecting beam, and meanwhile, the structure is simple, large-scale casting equipment or a machining center is not needed for production, the connecting beam can be manufactured by simple plate splicing welding, the cost is lower, and the practicability is good; moreover, the design can be flexibly changed, the adaptability is good, a person skilled in the art can finish the design modification and calculation verification processes only by 1 to 2 working days according to different application requirements, and then finish the processing modification or the remanufacturing in a short time.

Example two: a drawing type connecting beam.

The present embodiment is different from the first embodiment in that the first end plate 105, the first bayonet lug plate 110, the second end plate 205, the second bayonet lug plate 209, the first operation hole 108, the second operation hole 208, the first pin hole 106, the second pin hole 107, the third pin hole 206, and the fourth pin hole 207 are omitted. Meanwhile, as shown in fig. 9, a plurality of stepped holes 112 are formed in the first plate 101, a plurality of first screw holes 211 are formed in the second plate 201 to match the stepped holes 112, and the coupling member is changed from the latch assembly 3 to the bolts 4, and the bolts 4 are disposed in the stepped holes 112 and detachably fix the drawn outer beam 1 and the drawn inner beam 2 through the first screw holes 211.

The threaded connection has higher strength, but the operation is not as convenient as the pin connection during connection, and the bearing device is suitable for occasions with higher bearing requirements. As a variation of this embodiment, the first reinforcement 104 and the second reinforcement 204 may be omitted, and the outer girt 1 may be designed to have a square steel shape, and the inner girt 2 may be designed to have a matching square steel shape or a simple steel plate shape. In order to facilitate the installation and the disassembly of the drawable coupling beam, a telescopic leg, for example, a telescopic leg composed of a flange nut and a lead screw, may be further provided at the bottom of the first reinforcement 104, so as to support and fine-tune the height during the installation and the disassembly of the drawable coupling beam, and may be used in place of a hydraulic vehicle or a jack, and is suitable for the occasions requiring relatively frequent disassembly and assembly or length adjustment. The stepped holes 112 may also be provided in the first side plate 102 and the second side plate 103, and the first threaded holes 211 are provided in the third side plate 202 and the fourth side plate 203, respectively, and similar functions may be achieved. In addition, as the pin shaft 301 of the first embodiment has a certain self-positioning function, the corresponding pin holes are easily inserted in the sliding adjustment process of the outer drawing beam 1 and the inner drawing beam 2, and the bolts 4 are not easily and quickly connected in the adjustment process; therefore, the pin-hole connection of the first embodiment and the bolt connection of the second embodiment can be combined, that is, a plurality of pins 301, for example, 1 pin on each of two sides, are adopted, after the pulling length of the outer pulling beam 1 and the inner pulling beam 2 is adjusted to be basically in place, the corresponding pin holes are relatively easily inserted in time, so that the outer pulling beam 1 and the inner pulling beam 2 are accurately positioned, and at the moment, the bolts 4 can be conveniently and fixedly connected through the first threaded holes 211.

Example three: a modular transport vehicle.

The modular transporter of the embodiment includes two SPMT modules 5 and a pull-out coupling beam of the embodiment one, the pull-out outer beam 1 is connected to one SPMT module 5, and the pull-out inner beam 2 is connected to another SPMT module 5, so as to form a hard splicing between the SPMT modules 5. As shown in fig. 10 and 11, the SPMT module 5 has eight fourth threaded holes 503 at both ends, a first ear plate pin interface 501 at a first end thereof, and a second ear plate pin interface 502 at a second end thereof.

The present embodiment also includes a PPU power head that is connected to the first end of the first SPMT module 5 and provides hydraulic power and control to all of the SPMT modules 5. The second end of the first SPMT module 5 is connected to the drawn outer beam 1 and the drawn inner beam 2 is connected to the drawn outer beam 1 of the second SPMT module 5. The connection includes mechanical connection and electrical and hydraulic connection. The mechanical connection includes: the PPU power head is mechanically connected with a first end of the first SPMT module 5; the second end of the first SPMT module 5 is connected with the drawing outer beam 1 through a fourth threaded hole 503 and a second threaded hole 111 by a stud bolt and connected with the second lug plate plug-pin interface 502 and the first plug plate lug 110 by a hydraulic plug pin; the third threaded hole 210 and the fourth threaded hole 503 are connected between the inner drawing beam 2 and the first end of the second SPMT module 5 through a stud bolt, and the second bolt lug 209 and the first lug bolt interface 501 are connected through a hydraulic bolt. The electrical connection and the hydraulic connection are realized through an electrical trunk line and a hydraulic trunk pipe of the drawing type connecting beam and a corresponding interface, an aviation socket or an aviation plug.

When the two SPMT modules 5 are connected by the pull-type connecting beam, the pull-type connecting beam can be adjusted to a proper height by the hydraulic vehicle or the jack or the adjustable support arranged on the pull-type outer beam 1, and then the connection operation can be carried out. After the connection is completed, the supporting equipment or device can be removed or retracted, and the length is adjusted. The sliding between the drawn outer beam 1 and the drawn inner beam 2 can be achieved by the power of the SPMT module 5 without a special device. A guide rail or a slider or a roller for reducing friction may be further provided between the withdrawal outer beam 1 and the withdrawal inner beam 2 to further reduce the friction force at the time of sliding.

As a variation of this embodiment, a plurality of the same or different SPMT modules may be connected by a plurality of the same or different pull-out connecting beams in a similar manner; the width of the pull-out connecting beam does not need to be the same as that of the SPMT module 5, for example, the SPMT module with a larger width can be connected by a narrower pull-out connecting beam, or connected by more than two narrower pull-out connecting beams; the drawing type connecting beams can also be connected in series. The fourth threaded hole 503, the first ear plate pin interface 501 and the second ear plate pin interface 502 are common settings of the SPMT module, but other connection modes can be adopted, and only the connection interface of the pull-out connecting beam needs to be matched with the connection interface of the SPMT module. In addition, the drawing type connecting beam can also be used for transverse connection between SPMT modules, and the effect of adjustable connection distance can also be realized.

The foregoing is only a preferred embodiment of the present application and the technical principles employed, and various obvious changes, rearrangements and substitutions may be made without departing from the spirit of the application. Other advantages and effects of the present application will be readily apparent to those skilled in the art from the disclosure herein.
