Description

Technical Field

[0001] The present invention relates to the technical field of railway freight cars, and more specifically to a prefabricated beam transport support device and a prefabricated beam transport support device group. Background Art

[0002] Precast beams are beams that are molded, mixed, and poured at a concrete component factory or construction site. When the strength of the precast beams reaches the design requirements, they are transported to the construction site and installed and fixed in the position required by the design. At the same time, with the development of transportation, some bridges cannot meet the planning requirements, and some bridges have to be dismantled and shipped out for crushing. During the transportation process, the precast beams are bumpy due to the bumps of the vehicle, the precast beams themselves are heavy, and they are easy to slide relative to the vehicle, making the precast beams unstable and easy to fall off.

[0003] Based on this, in the prior art, the transportation method of railway prefabricated beams mainly adopts to set sleepers on the transport vehicle, place the prefabricated beams on the sleepers, and set diagonal support devices on both sides of the sleepers. When transporting the prefabricated beams, the prefabricated beams are placed on the sleepers, and the diagonal support devices on both sides are used to support and reinforce the prefabricated beams to prevent the prefabricated beams from sliding due to the bumps of the vehicle during transportation, which eventually leads to detachment and damage.

[0004] However, although the reinforcement method in the prior art can support the prefabricated beam, the support device is not suitable for prefabricated beams that are long and need to be transported across vehicles. Long prefabricated beams need to be transported on two or three vehicles. When the train runs on a curved track, the two vehicles will deflect, which will inevitably cause the prefabricated beam to move on the two vehicles, affecting the safety of prefabricated beam transportation.

DETAILED DESCRIPTION

[0030] The core of the present invention is to provide a prefabricated beam transport support device to meet the loading and reinforcement requirements of prefabricated beams of various specifications on railway freight cars; Another core of the present invention is to provide a precast beam transport support device group having the above-mentioned precast beam transport support device.

[0031] The following embodiments are described with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the invention contents described in the claims. In addition, the entire contents of the structures represented by the following embodiments are not limited to those necessary as solutions to the inventions described in the claims. It should be noted that, for ease of description, only the parts related to the inventions are shown in the accompanying drawings. The embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0032] like Figure 1-Figure 4 and Figure 8 As shown, the prefabricated beam transport support device disclosed in the embodiment of the present invention includes a steering wheel base 110, a steering wheel 120 and a support rod device 130. The steering wheel base 110 is used to be arranged on the body of a railway freight car, and the fixing method of the steering wheel base 110 and the body is not limited. For example, the steering wheel base 110 can be assembled by fixing with fasteners.

[0033] The steering wheel 120 is rotatably arranged on the steering wheel base 110. The steering wheel 120 has a prefabricated beam bearing area 124. When in use, the prefabricated beam is supported on the prefabricated beam bearing area 124. During transportation, when there is a vehicle turning scene, the steering wheel 120 will rotate relative to the steering wheel base 110 according to the deflection requirement of the prefabricated beam.

[0034] The support rod device 130 is hinged on the steering wheel 120, and the support rod device 130 is provided on both sides of the precast beam bearing area 124. The support rod devices 130 on both sides of the precast beam bearing area 124 are used to support the precast beam from both sides of the precast beam. The support rod device 130 can change the angle by rotating so that it can be supported on both sides of the precast beam. The precast beam can be fixed to the steering wheel 120 by the support rod device 130 to prevent the precast beam from shaking relative to the steering wheel 120.

[0035] The prefabricated beam transport support device provided by the present invention can be used to support the transported prefabricated beam after being applied to the vehicle body. In particular, when the prefabricated beam is long and needs to cross multiple vehicle bodies, the two ends of the prefabricated beam can be supported on the prefabricated beam bearing areas 124 of the two prefabricated beam transport support devices respectively. When the railway freight car passes through a curved track, the vehicle bodies that respectively bear the head end and the tail end of the prefabricated beam will produce angle changes, and the steering wheel 120 of the prefabricated beam transport support device provided by the present invention can rotate relative to the steering wheel base 110, so when the railway freight car turns, the prefabricated beam can be stably supported on the prefabricated beam transport support device, and the steering wheel 120 of the prefabricated beam transport support device moves according to the turning angle. That is, when the railway freight car turns, the steering wheel base 110 fixed on the vehicle body will change the angle with the vehicle body, while the steering wheel 120 can remain stationary to keep the two steering wheels 120 fixed at both ends of the prefabricated beam continue to remain on the same straight line, prevent the angle change due to the vehicle body, and ensure that the prefabricated beam can be safely and stably transported on the railway freight car.

[0036] The present invention can meet the loading and reinforcement requirements of precast beams of various specifications on railway freight cars, that is, the longer the length of the precast beam, the more car bodies it needs to cross. For example, a 24m precast beam can be carried by two car bodies; a 36m precast beam can be carried by three car bodies. When three car bodies are required to carry it, precast beam transportation support devices are set on the first car body and the third car body to support the two ends of the 36m precast beam respectively, and there is no need to set a precast beam transportation support device on the second car body. It can be understood by those skilled in the art that the precast beam transportation support device disclosed in this embodiment can be applied to precast beams of various lengths. It is only necessary to fix two precast beam transportation support devices at corresponding positions of the car body according to the length of the precast beam.

[0037] like Figure 5 and Figure 6 As shown, a sliding groove 114 is provided on the steering wheel base 110 disclosed in the first embodiment of the present invention. The sliding groove 114 extends along a first direction, which is the length direction of the vehicle body. Two sets of support rod devices 130 are arranged on both sides of the prefabricated beam bearing area 124 along a second direction, and the first direction is perpendicular to the second direction.

[0038] like Figure 8 and Fig. 9As shown, a steering shaft 125 is provided on the side of the steering wheel 120 facing the steering wheel base 110, and the steering shaft 125 extends into the sliding groove 114. Since the part of the steering wheel base 110 that cooperates with the steering shaft 125 is the sliding groove 114, the steering shaft 125 can not only rotate relative to the sliding groove 114, but also move along the sliding groove 114. In this way, the steering wheel 120 can not only rotate relative to the steering wheel base 110, but also move relative to the steering wheel base 110 in a first direction, that is, move along the length direction of the vehicle body.

[0039] like Figure 7 As shown, one of the steering wheel base 110 and the steering wheel 120 disclosed in the second embodiment of the present invention is provided with a steering hole 117, and the other is provided with a steering shaft 125, and the steering shaft 125 is rotatably matched with the steering hole 117. For example, the steering wheel base 110 is provided with a steering hole 117, and the steering wheel 120 is provided with a steering shaft 125. Since the steering shaft 125 is rotatably matched with the steering hole 117, the steering wheel 120 can only rotate relative to the steering wheel base 110.

[0040] To summarize, the difference between the scheme disclosed in the first embodiment and the scheme disclosed in the second embodiment lies in that the structure on the steering wheel base 110 disclosed in the first embodiment that cooperates with the steering shaft 125 is the sliding groove 114, while the structure on the steering wheel base 110 disclosed in the first embodiment that cooperates with the steering shaft 125 is the steering hole 117; apart from this, the other structures of the prefabricated beam transport support devices disclosed in the two embodiments are the same (meaning that the structures are the same, but differences in size are allowed, for example, the diameters and lengths of the steering shafts 125 disclosed in the two embodiments may be different, and the sizes of the two steering wheel bases 110 may also be different).

[0041] This embodiment discloses two precast beam transport support devices, one having a sliding groove 114 and the other having a steering hole 117, that is, one can realize rotation and movement, and the other can only realize rotation. In actual application, the two precast beam transport support devices can support the two ends of the precast beam respectively. Take the front end in the travel direction as the precast beam transport support device disclosed in the first embodiment (for the sake of ease of understanding, defined as the first precast beam transport support device), and the rear end as the precast beam transport support device disclosed in the second embodiment (for the sake of ease of understanding, defined as the second precast beam transport support device) as an example.

[0042] When the railway freight car turns, the steering wheel base 110 fixed on the car body will change its angle with the car body, while the steering wheel 120 can remain stationary to keep the two steering wheels 120 fixed at both ends of the precast beam on the same straight line. At the same time, since the straight-line distance between the two precast beam transport support devices changes when the car body turns, the steering wheel base 110 of the first precast beam transport support device will not only change its angle with the car body, but also move along the steering wheel base 110 according to the decrease in the straight-line distance between the two precast beam transport support devices, so as to prevent the precast beam from being damaged due to the decrease in the straight-line distance between the two precast beam transport support devices.

[0043] like Figure 7 and Fig. 9 As shown, in the precast beam transport support device disclosed in the second embodiment, the steering wheel base 110 is provided with a first turntable core disk 118, and the steering wheel 120 is provided with a second turntable core disk 127 that is rotatably matched with the first turntable core disk 118. One of the first turntable core disk 118 and the second turntable core disk 127 is a convex disk body, and the other is a concave disk body. One of the steering shaft 125 and the steering hole 117 is provided on the first turntable core disk 118, and the other is provided on the second turntable core disk 127, and the steering shaft 125, the steering hole 117, the first turntable core disk 118 and the second turntable core disk 127 are coaxially arranged. In this embodiment, by adding the first turntable core disk 118 and the second turntable core disk 127, the first turntable core disk 118 and the second turntable core disk 127 have larger diameters than the steering shaft 125 and the steering hole 117, so that the rotation of the steering wheel 120 and the steering wheel base 110 is more stable and reliable.

[0044] Furthermore, by providing the first turntable core disk 118 and the second turntable core disk 127, when the steering wheel 120 and the steering wheel base 110 rotate relative to each other, the main friction parts of the two are limited to the first turntable core disk 118 and the second turntable core disk 127, thereby preventing the steering wheel 120 and the steering wheel base 110 from rubbing against each other at other positions. The first turntable core disk 118 and the second turntable core disk 127 can be made of wear disks to resist wear.

[0045] In the prefabricated beam transport support device disclosed in the second embodiment, a wear-resistant bushing may be provided in the sliding groove 114 to improve the wear-resistant effect.

[0046] Those skilled in the art can understand that other structures of the precast beam transport support devices disclosed in Example 1 and Example 2 are the same, that is, the first precast beam transport support device and the second precast beam transport support device are the same in other aspects, and the first precast beam transport support device and the second precast beam transport support device will no longer be distinguished from each other in the following text. The specific structural features introduced in the following text can be applied to both the first precast beam transport support device and the second precast beam transport support device.

[0047] like Figure 6 and Figure 7 As shown, the steering wheel base 110 includes a longitudinal beam 111 and a transverse beam 112 that intersect each other. In this embodiment, the steering wheel base 110 is designed as a cross-shaped structure of the longitudinal beam 111 and the transverse beam 112, so that the steering wheel base 110 can provide a better support effect without significantly increasing the weight. The longitudinal beam 111 can extend in the length direction of the vehicle body, and the transverse beam 112 can extend in the width direction of the vehicle body.

[0048] In the initial state, the steering wheel 120 is arranged on the steering wheel base 110 in a direction parallel to the transverse beam 112. It should be noted that the initial state refers to the state when the steering wheel 120 does not rotate relative to the steering wheel base 110, that is, the state when the railway freight car is running on a straight track and the train bodies are on the same straight line. That is, when the railway freight car is running in a straight line, the steering wheel 120 is located directly above the transverse beam 112.

[0049] Furthermore, a side bearing base 113 is provided at the end of the transverse beam 112, and the width of the side bearing base 113 is greater than the width of the transverse beam 112. In the initial state, the steering wheel 120 extends above the side bearing base 113. Since the side bearing base 113 has a larger width than the transverse beam 112, when the steering wheel 120 moves and / or rotates, part of the structure can be kept overlapping with the side bearing base 113, so that the side bearing base 113 can provide support for the steering wheel 120 after the steering wheel 120 moves.

[0050] Further, such as Figure 6-Figure 9 As shown, a first wear plate 115 is provided on the side of the side bearing base 113 facing the steering wheel 120, and a second wear plate 126 is provided on the side of the steering wheel 120 facing the side bearing base 113. In this embodiment, the first wear plate 115 and the second wear plate 126 are fitted together to prevent the steering wheel 120 and the steering wheel base 110 from interfering during the relative movement. Specifically, the gap between the steering wheel 120 and the steering wheel base 110 can be adjusted by adjusting the thickness of the first wear plate 115 and / or the second wear plate 126. The first wear plate 115 and the second wear plate 126 are fitted together, so that when the steering wheel 120 moves relative to the steering wheel base 110, the first wear plate 115 and the second wear plate 126 rub against each other, thereby resisting wear, impact and vibration, and protecting the durability of the prefabricated beam transport support device.

[0051] like Figure 8 and 9As shown, in this embodiment, the steering wheel 120 may include a steering wheel body 121 and a limit stopper 122. The prefabricated beam bearing area 124 is located on the steering wheel body 121, and specifically, the prefabricated beam bearing area 124 may be arranged in the middle of the steering wheel body 121. The steering wheel body 121 may be formed by welding a plurality of plates.

[0052] The limit stopper 122 is arranged on the steering wheel body 121, and the limit stops 122 are arranged on both sides of the precast beam bearing area 124, and the two limit stops 122 form a limit for the precast beam. After the precast beam is placed in the precast beam bearing area 124, the two limit stops 122 can prevent the precast beam from moving and form a limit for the precast beam. In order to improve the reliability of the limit stopper 122, the limit stopper 122 can be supported by a plurality of diagonal bracing ribs, and the diagonal bracing ribs should be located on the side of the limit stopper 122 facing away from the precast beam bearing area 124. The limit stopper 122 is supported by the diagonal bracing ribs, so that even if the precast beam hits the limit stopper 122, the limit stopper 122 can maintain a certain resistance.

[0053] Furthermore, the prefabricated beam bearing area 124 may be provided with a wooden pad, which has a lower hardness. By supporting the prefabricated beam with the wooden pad, wear on the prefabricated beam can be avoided. In addition, the prefabricated beam is loaded on the upper part of the wooden pad, and the loading center of gravity of the prefabricated beam can be adjusted by adjusting the thickness of the wooden pad. A lifting ring 123 is provided on the steering wheel body 121 to facilitate the lifting equipment to lift the steering wheel 120 onto the steering wheel base 110 and install it.

[0054] like Figure 5-Figure 7 As shown, in this embodiment, the steering wheel base 110 may include a bottom plate body, an upper plate body located above the bottom plate body, and an intermediate support plate body connected between the bottom plate body and the upper plate body. In this embodiment, the steering wheel base 110 is welded from a plurality of plates, which can reduce the weight of the steering wheel base 110 while ensuring the supporting effect.

[0055] The bottom plate is used to be fixed to the vehicle body by fasteners, and the upper plate is provided with fastener operation holes 116 at the corresponding positions of the fasteners. Since the distance between the bottom plate and the upper plate is not too large, the tightening wrench cannot operate the fastener through the space between the bottom plate and the upper plate. Therefore, in this embodiment, the fastener operation holes 116 are provided at the corresponding positions of the upper plate and the fasteners, and the tightening wrench can rotate the fasteners on the bottom plate through the fastener operation holes 116 above the upper plate.

[0056] like Fig.10As shown, the support rod device 130 may include a support rod body and a support pad assembly 135, and the support rod body includes a support rod sleeve 131, a first connecting rod 132, a second connecting rod 133 and a rotating shaft seat 134. The support rod sleeve 131 has a first threaded hole and a second threaded hole, one end of the support rod sleeve 131 is the first threaded hole, and the other end is the second threaded hole, and the first threaded hole and the second threaded hole have opposite rotation directions.

[0057] The first connecting rod 132 is threadedly matched with the first threaded hole, the second connecting rod 133 is threadedly matched with the second threaded hole, and the support pad assembly 135 is connected to the second connecting rod 133 to support the prefabricated beam. The rotating shaft seat 134 is arranged on the steering wheel 120, and the first connecting rod 132 is hinged to the rotating shaft seat 134.

[0058] The first connecting rod 132 is connected to the rotating shaft seat 134, and the rotating shaft seat 134 is arranged on the steering wheel 120, thereby realizing the hinge connection between the support rod body and the steering wheel 120, so that the support rod body can be rotated through the rotating shaft seat 134. After the precast beam is placed, the support rod body can be rotated to make the support pad assembly 135 at the end of the second connecting rod 133 abut against the side of the precast beam, thereby completing the support of the side of the precast beam. Usually, the support pad assembly 135 can be abutted against the lower edge of the precast beam.

[0059] Since the specifications of the prefabricated beams are different, the required lengths of the brace bodies are different. In this embodiment, the first connecting rod 132 and the second connecting rod 133 are installed at both ends of the brace sleeve 131. Since the first threaded hole and the second threaded hole have opposite rotation directions, the first connecting rod 132 and the second connecting rod 133 can be moved synchronously by rotating the brace sleeve 131, and the moving directions are opposite, that is, they move closer to each other (shortening the length of the brace body) and move away from each other (increasing the length of the brace body). By rotating the brace sleeve 131, the length of the first connecting rod 132 and the second connecting rod 133 extending outside the brace sleeve 131 can be changed, thereby adjusting the length of the brace body to adapt to the prefabricated beams of corresponding specifications.

[0060] In order to improve the support effect, Figure 1 As shown, the brace device 130 on either side of the precast beam bearing area 124 includes two brace bodies, and the two brace bodies are connected to the same brace pad assembly 135. When the two brace bodies are connected to the same brace pad assembly 135, the two brace bodies are in a herringbone shape, that is, the two brace bodies are arranged at an acute angle.

[0061] like Fig.11As shown, in this embodiment, the pad assembly 135 may include a pad support body 1352, a pad body 1351 and a support rod hinge seat 1353. Among them, the pad support body 1352 serves as the supporting body of the pad assembly 135, and is used to provide an installation foundation for other components. The pad body 1351 is arranged on the first side of the pad support body 1352, and the pad body 1351 is a flexible material body. The pad body 1351 is used to abut against the prefabricated beam. Since the pad body 1351 is a flexible material body, the pad body 1351 abuts against the prefabricated beam, which has a certain buffering effect, and the non-rigid contact can protect the prefabricated beam from being damaged due to inertia, impact, etc.

[0062] The support rod hinge seat 1353 is provided with a connection hole 1354 hinged to the two support rod bodies, and the second connection rods 133 of the two support rod bodies are respectively connected to the two connection holes 1354 through the hinge shaft. Specifically, the support rod hinge seat 1353 includes two support plates, and a space is formed between the two support plates for the end of the second connection rod 133 to be inserted, and the connection hole 1354 passes through the two support plates.

[0063] The second connecting rod 133 of one of the support rod bodies is hinged to one of the connecting holes 1354 through a fixed pin. When the connecting end of one of the second connecting rods 133 extends between the two support plates and ensures that the upper hole of the connecting end of the second connecting rod 133 is connected to the connecting holes 1354 on the two support plates, a fixed pin can be inserted for hinge connection.

[0064] The second connecting rod 133 of the other support rod body is hinged to the other connecting hole 1354 through the sliding pin 1355, and the sliding pin 1355 is slidably matched on the support pad support body 1352. That is, in this embodiment, one second connecting rod 133 is hinged through the fixed pin, and the other second connecting rod 133 is hinged through the sliding pin 1355.

[0065] When the railway freight car is not transporting precast beams, the strut device 130 needs to be laid down to prevent the strut device 130 from shaking and colliding with other structures. Since the two strut bodies are connected to a support pad assembly 135, when the strut device 130 needs to be laid down, at least one of the strut bodies needs to be disassembled from the support pad assembly 135, otherwise it cannot be laid down. In this embodiment, only the strut body hinged by the sliding pin 1355 needs to be disassembled, and the other strut body hinged by the fixed pin can maintain the connection with the support pad assembly 135 without disassembly. Figure 2 As shown, the brace body on the left is disconnected from the brace pad assembly 135 , while the brace body on the right remains connected to the brace pad assembly 135 .

[0066] like Fig.10As shown, the rotating shaft seat 134 can output swinging along the width direction of the vehicle body (i.e., the swinging plane is the width direction of the vehicle body), and the support rod body is hinged with the output end of the rotating shaft seat 134, so that the support rod body can swing along the length direction of the vehicle body relative to the output end (i.e., the swinging plane is the length direction of the vehicle body). That is, the support rod body can swing along the width direction and length direction of the vehicle body through the connection with the rotating shaft seat 134. By swinging along the width direction of the vehicle body (i.e., the rotation axis is parallel to the length direction of the vehicle body), the support pad assembly 135 can be abutted against the prefabricated beam; by swinging along the length direction of the vehicle body (i.e., the rotation axis is parallel to the width direction of the vehicle body), the support rod body can be laid on the vehicle body and extended along the length direction of the vehicle body.

[0067] like Figure 1 As shown, in order to fix the fallen support rod body, in this embodiment, the precast beam transport support device may also include a support rod support 140 for being arranged on the vehicle body, and a slot is formed on the top of the support rod support 140. The opening of the slot can be designed as a flared interface to facilitate the insertion of the support rod device 130 into the slot. In this embodiment, when the support rod device 130 is idle, it can be inserted into the slot of the support rod support 140, and the support rod body of the support rod device 130 can be fixed by the support rod support 140, and specifically, the support rod sleeve 131 can be inserted into the slot. In addition, the support rod support 140 and the rotating shaft seat 134 may not be on the same straight line (that is, the support rod support 140 is not on the connecting line of the two rotating shaft seats 134 on the same side of the precast beam bearing area 124, but the deviation distance cannot be too large, otherwise the support rod body cannot be inserted into the slot), and the angle formed can play a role in fixing the support rod body.

[0068] like Fig.11 As shown, a guide rod is provided on the support pad support body 1352, and a sliding pin 1355 can be slidably sleeved on the guide rod, and the guide rod can be fixed on the support plate, and the support plate is fixed on the support pad support body 1352. The sliding pin 1355 and the guide rod are coaxially arranged with one of the connection holes 1354, and the sliding pin 1355 can be slid into the connection hole 1354 or slid out of the connection hole 1354 by sliding the sliding pin 1355. After sliding into the connection hole 1354, the connection with the support rod body can be realized, and after sliding out of the connection hole 1354, the disassembly from the support rod body can be realized, which improves the disassembly and assembly efficiency with the support rod body.

[0069] In order to ensure that the sliding pin 1355 will not be easily disengaged after being connected to the support rod body, in this embodiment, the support pad support body 1352 is movably connected with a sliding pin baffle 1356, and after the sliding pin 1355 is inserted into the connection hole 1354, the sliding pin baffle 1356 is used to resist the sliding pin 1355. Specifically, the sliding pin baffle 1356 can be hinged on the support pad support body 1352, and when the support rod device 130 is erected for use, the sliding pin baffle 1356 will swing downward under the action of gravity and overlap on the guide rod, and can resist the exit path of the sliding pin 1355, preventing the sliding pin 1355 from falling out of the connection hole 1354, thereby improving the safety of use.

[0070] like Fig.10 As shown, the support rod sleeve 131 is provided with a collar 136 and / or an auxiliary rotation socket 137. The collars 136 on the two support rod bodies of the support rod device 130 can be connected by a rope to prevent the support rod sleeve 131 from rotating and ensure the supporting effect. The auxiliary rotation socket 137 can be inserted with a tool such as a chisel to rotate the support rod sleeve 131 by levering, thereby achieving the purpose of saving effort.

[0071] The embodiment of the present invention further discloses a precast beam transport support device group, including a first precast beam transport support device and a second precast beam transport support device. The first precast beam transport support device is a precast beam transport support device with a sliding groove 114; the second precast beam transport support device is a precast beam transport support device with a turning hole 117, and the first precast beam transport support device and the second precast beam transport support device are respectively used to support the two ends of the precast beam.
