Description

Technical Field

[0001] This application relates to the field of tunnel boring machine cutterhead transportation technology, and in particular to a high-load-bearing transportation vehicle. Background Technology

[0002] Currently, in subway construction, traditional construction methods often fail to meet requirements due to limitations imposed by the urban environment, such as construction sites and road traffic. To minimize the impact on normal urban functions, tunnel boring machine (TBM) construction has emerged and is widely used.

[0003] With the continuous development and application of tunnel boring machine (TBM) construction methods for subways, TBMs play a crucial role in the tunnel excavation process. However, during construction, the TBM cutterhead may experience various malfunctions, requiring repair or replacement. Because the TBM cutterhead is quite heavy, typically weighing 50 to 70 tons, the transport vehicle needs sufficient load-bearing capacity to move it in and out of the tunnel.

[0004] However, in current subway tunnel boring machine (TBM) construction, the height of the chassis is difficult to control due to limitations in the size of the steel profiles, making it impossible to meet the clearance requirements of customers. Furthermore, the existing transport vehicle chassis cannot withstand large loads due to insufficient load-bearing capacity, severely hindering construction progress. Summary of the Invention

[0005] This application provides a high-load-bearing transport vehicle to solve the problems of insufficient load-bearing capacity and limited height of the flatcar for transporting the cutterhead of a tunnel boring machine.

[0056] Tunnel boring machines (TBMs) play a crucial role in excavating underground spaces such as tunnels and subways. During prolonged operation, the cutterhead of a TBM may malfunction and require maintenance. Due to the significant weight of the cutterhead, transport vehicles with sufficient load-bearing capacity are needed to move it in and out of the tunnel.

[0057] In view of this, the embodiments of this application provide a car frame, a center plate, and a bogie. The car frame includes a box-type structure, comprising an upper cover plate, a lower cover plate, and a support assembly located between the upper and lower cover plates. The upper and lower cover plates are connected by the support assembly, and there is a gap between them. The center plate is located on the side of the lower cover plate facing away from the upper cover plate. The bogie is connected to the center plate. The box-type structure composed of the upper cover plate, lower cover plate, and support assembly effectively improves the load-bearing strength, enhances the stability and bending resistance of the car frame, and ensures that the car frame has sufficient load-bearing capacity to support the transport of the tunnel boring machine cutterhead.

[0058] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0060] like Figure 1 and Figure 2 As shown, the high-load-bearing transport vehicle provided in this embodiment includes a body frame 100, a center plate 200, a bogie 300, wheels 400, and a braking system 500. The body frame 100 and the bogie 300 are connected via the center plate 200. The wheels 400 are mounted on the bogie 300 for rotation control. The braking system 500 is connected to the wheels 400 and brakes the wheels 400.

[0061] In some embodiments of this application, such as Figure 3 and Figure 4 As shown, the vehicle frame 100 includes a box-type structure 101. The box-type structure 101 includes an upper cover plate 110, a lower cover plate 120, and a support assembly 102 located between the upper cover plate 110 and the lower cover plate 120. The upper cover plate 110 and the lower cover plate 120 are connected by the support assembly 102, and there is a gap between the upper cover plate 110 and the lower cover plate 120. That is, the box-type structure 101 is composed of an upper cover plate 110, a lower cover plate 120, and a support assembly 102. There is a certain gap between the upper cover plate 110 and the lower cover plate 120 to accommodate the support assembly 102. The support assembly 102 is used to support and connect the upper cover plate 110 and the lower cover plate 120 to ensure a firm connection between the upper cover plate 110 and the lower cover plate 120. In addition, the box-type structure 101 can enhance the strength and stability of the vehicle frame 100. It should be noted that the upper cover plate 110, the lower cover plate 120 and the support component 102 are all made of steel plate, to avoid the conventional use of structural steel which would result in a single size of the vehicle frame 100 and fail to meet the requirement of controllable size of the vehicle frame 100.

[0062] In some embodiments of this application, the support component 102 includes at least two sets of side beam structures 130, but is not limited to two sets of side beam structures 130; it can have two or more sets, such as three or four sets. This application embodiment specifically uses two sets as an example, such as... Figure 4 As shown, only a portion of the side beam structure 130 is illustrated. Each set of side beam structures 130 includes two first web plates 131 and several first partition plates 132. The two ends of each first partition plate 132 are connected to the two first web plates 131 respectively, and the first partition plates 132 are perpendicularly connected to the two first web plates 131. The two sets of side beam structures 130 are located within the interval between the upper cover plate 110 and the lower cover plate 120. Furthermore, each set of side beam structures 130 is disposed on both sides of the upper cover plate 110 and the lower cover plate 120 along the X-axis direction. By providing side beam structures 130 with torsional and bending resistance, the strength and stability of the box structure 101 are further enhanced.

[0063] For example, such as Figure 6 As shown, each set of side beam structures 130 comprises two first web plates 131 and four first partition plates 132. The two ends of each first partition plate 132 are connected to the two first web plates 131 respectively, and the first partition plates 132 are perpendicular to the first web plates 131. It should be noted that the number of first partition plates 132 can be four, but is not limited to four; for example, it can be five or six. In this embodiment, the first partition plates 132 are arranged in pairs evenly, and the first partition plates 132 are arranged axially symmetrically with respect to the center position of the first web plates 131. It should be noted that the first partition plates 132 can be arranged symmetrically as described above, but is not limited to this arrangement; for example, they can be arranged asymmetrically.

[0064] In some embodiments of this application, the support component 102 includes at least two sets of crossbeam structures 140, but is not limited to two sets of crossbeam structures 140; it can have two or more sets, such as three or four sets. This application embodiment specifically uses two sets as an example, such as... Figure 4 As shown, only one set of crossbeam structures 140 is illustrated. Each set of crossbeam structures 140 includes two second webs 141 and several second partitions 142. The two ends of each second partition 142 are connected to the two second webs 141 respectively, and the second partitions 142 are perpendicularly connected to the two second webs 141. The two sets of crossbeam structures 140 are located within the Y-axis interval between the upper cover plate 110 and the lower cover plate 120. In addition, one end of each crossbeam structure 140 is connected to a set of side beam structures 130, and the other end of each crossbeam structure 140 is connected to another set of side beam structures 130.

[0065] For example, such as Figure 7As shown, each beam structure 140 comprises two second webs 141 and one second partition 142. The two ends of the second partition 142 are connected to the two second webs 141 respectively, and the second partition 142 is perpendicular to the second webs 141. It should be noted that the number of second partitions 142 can be single, but is not limited to single; for example, it can be two or three. In this embodiment, the second partitions 142 are arranged at the center of the second webs 141, but are not limited to the above arrangement. For example, when there are two second partitions 142, they can be arranged symmetrically with respect to the center of the second webs 141, or asymmetrically.

[0066] In some embodiments of this application, the support component 102 further includes at least three sets of longitudinal beam structures 150, but is not limited to three sets of longitudinal beam structures 150; it can be any number of sets, such as two or four sets. This application embodiment specifically uses three sets as an example, such as... Figure 4 As shown, only a portion of the longitudinal beam structure 150 is illustrated. Each set of longitudinal beam structures 150 includes two third web plates 151 and several third partition plates 152. The two ends of each third partition plate 152 are connected to the two third web plates 151 respectively, and the third partition plates 152 are perpendicularly connected to the two third web plates 151. The three sets of longitudinal beam structures 150 are arranged in the interval along the X-axis between the upper cover plate 110 and the lower cover plate 120, located between the side beam structure 130 and the crossbeam structure 140, and one end of each longitudinal beam structure 150 is connected to the center of the crossbeam structure 140.

[0067] For example, such as Figure 8 As shown, each set of longitudinal beam structures 150 comprises two third webs 151 and four third partitions 152. The two ends of each third partition 152 are connected to the two third webs 151, and the third partitions 152 are perpendicular to the third webs 151. It should be noted that the number of third partitions 152 can be four, but is not limited to four; for example, it can be five or six. In this embodiment, the third partitions 152 are arranged in pairs, evenly distributed, and are axially symmetrical with respect to the center position of the third webs 151. It should be noted that the third partitions 152 can be arranged symmetrically as described above, but are not limited to this arrangement; for example, they can be arranged asymmetrically.

[0068] The side beam structure 130, cross beam structure 140, and longitudinal beam structure 150 work together to form a more complete support system for the support assembly 102, better distributing and dispersing external loads, and improving the vehicle's load-bearing capacity and driving stability. It should be noted that the support assembly 102 can be connected to the upper cover plate 110 and lower cover plate 120 by welding, but is not limited to welding. For example, bolted connections are also possible.

[0069] Please continue reading. Figure 1 , Figure 3 and Figure 4 The upper cover plate 110 has two openings 111 for positioning the connection between the body frame 100 and the center plate 200. The center plate 200 is connected to the lower cover plate 120 of the body frame 100 by a center plate bolt 210. The openings 111 in the upper cover plate 110 facilitate the tightening of the center plate bolt 210 between the lower cover plate 120 and the center plate 200. In this embodiment, the opening 111 is circular, as shown below. Figure 4 As shown. It should be noted that the shape of the opening 111 can be circular but is not limited to being circular. For example, it can be square, etc.

[0070] In some embodiments of this application, the lower cover plate 120 is provided with rectangular holes (not shown in the figures). It should be noted that the rectangular holes are formed on the lower cover plate 120 according to the shape and size of the support assembly 102, and are used for the connection and positioning between the support assembly 102 and the lower cover plate 120. Through the rectangular holes, the side beam structure 130, the cross beam structure 140, and the longitudinal beam structure 150 can be accurately welded to the lower cover plate 120, ensuring the correct positioning of the side beam structure 130, the cross beam structure 140, and the longitudinal beam structure 150. This allows the side beam structure 130, the cross beam structure 140, and the longitudinal beam structure 150 to effectively support and stabilize the upper cover plate 110 and the lower cover plate 120, ensuring safety during the transport of the tunnel boring machine cutterhead.

[0071] For example, such as Figure 1 and Figure 3 As shown, the side of the lower cover plate 120 facing away from the upper cover plate 110 is also provided with a center plate seat plate 121, and the center plate 200 is connected to the lower cover plate 120 through the center plate seat plate 121. It should be noted that one end of the center plate 200 is connected to the center plate seat plate 121 provided on the lower cover plate 120 of the car body frame 100, and the other end of the center plate 200 is connected to the bogie 300. The car body frame 100 and the bogie 300 are stably connected through the center plate 200, thereby effectively transferring the weight of the car body frame 100 and the external load to the bogie 300, and then to the wheels 400 and the ground, ensuring the stability and safety of the high-load transport vehicle.

[0072] In some embodiments of this application, the vehicle frame 100 includes at least two end plates 160. The end plates 160 are disposed at both ends of the vehicle frame 100 and connected to the upper cover plate 110 and the lower cover plate 120, forming a box-like structure 101 with all four sides closed. A traction structure 170 is provided on one side of the end plate 160, and a stiffening rib 161 is provided on the other side of the end plate 160. The end plate 160 is connected to the lower cover plate 120 via the stiffening rib 161. Figure 2 and Figure 3As shown, end plates 160 are located at both ends of the vehicle frame 100 and are connected to the upper cover plate 110 and the lower cover plate 120 respectively, so that the vehicle frame 100 forms a box structure 101, which increases the structural strength and stability of the vehicle frame 100 and enables it to better withstand external loads.

[0073] Please continue reading. Figure 2 A traction structure 170 is provided on one side of the end plate 160, providing additional support and fixation to ensure a secure and reliable connection between the vehicle frame 100 and the towing vehicle (not shown in the figure) or adjacent vehicle frames 100. Figure 3 As shown, a stiffener 161 is provided on the other side of the end plate 160. The end plate 160 is tightly connected to the lower cover plate 120 through the stiffener 161, which not only strengthens the structural strength and stability of the car body frame 100, but also helps to improve the maneuverability of the traction vehicle over the car body frame 100 during operation.

[0074] In some embodiments of this application, such as Figure 5 As shown, the traction structure 170 includes at least two first seat plates 171, a fourth partition plate 1712, a triangular rib 1713, and a traction pin 1714. The first seat plates 171 are vertically disposed on the end plate 160 and connected to the end plate 160 via the triangular rib 1713, with a gap between the two first seat plates 171 to accommodate the fourth partition plate 1712. A first hole 1711 is provided on the first seat plate 171, and the traction pin 1714 is installed in the first hole 1711. That is, the first seat plates 171 are vertically welded to the side of the end plate 160 facing away from the upper cover plate 110 and the lower cover plate 120, and are reinforced by two triangular ribs 1713, with a gap between the two first seat plates 171 to accommodate the fourth partition plate 1712. For example, as... Figure 5 As shown, two first seat plates 171, two third partition plates 152, and four triangular ribs 1713 are interconnected and vertically welded onto the end plate 160 to form a box-type tow unit. The first seat plate 171 has a first hole 1711 to facilitate the installation and use of the towing pin 1714. The towing pin 1714 connects the front and rear vehicle frames 100 to realize the connection between adjacent vehicles.

[0075] In some embodiments of this application, such as Figure 5 and Figure 9As shown, the traction structure 170 also includes at least two second seat plates 172 and a safety chain (not shown in the figure). The second seat plates 172 are disposed on the end plate 160, located on both sides of the first seat plate 171. The second seat plates 172 have second holes 1721, and the safety chain is installed in the second holes 1721. That is, each second seat plate 172 is vertically disposed on the side of the end plate 160 opposite to the upper cover plate 110 and the lower cover plate 120, and located on both sides of the first seat plate 171, making the traction structure 170 symmetrical and further enhancing the safety and stability of the traction structure 170. The second holes 1721 on the second seat plates 172 facilitate the installation and use of the safety chain, providing additional fixing and enabling the front and rear vehicles to be interconnected, thus improving driving safety.

[0076] It should be noted that the safety chain is made of high-strength materials and can be steel wire rope or iron chain, but is not limited to steel wire rope or iron chain.

[0077] In some embodiments of this application, such as Figure 1 and Figure 2 As shown, the vehicle frame 100 also includes a mounting bracket 190, which is welded and fixed to the side of the upper cover plate 110 facing away from the lower cover plate 120, for securing the transported goods. The dimensions of the mounting bracket 190 are designed according to the dimensions and weight of the transported goods to ensure it can withstand various forces and pressures during transportation. The tunnel boring machine cutterhead can be placed horizontally on the mounting bracket 190 and secured with bolts for transport.

[0078] In some embodiments of this application, the lower cover plate 120 of the vehicle frame 100 is also provided with at least two side bearings 122, but is not limited to two; there can be three or four. This application embodiment specifically takes two side bearings 122 as an example. Figure 3 As shown, two side bearings 122 are provided on one side of the lower cover plate 120 opposite to the upper cover plate 110. It should be noted that the side bearings 122 are devices that support and protect the vehicle body from rolling and tilting, used to bear part of the load when the vehicle frame 100 turns through a curve, improving the stability and safety of the vehicle frame 100 and ensuring smooth curve driving. The number and angle of the side bearings 122 need to be designed according to the specific working conditions, the structural dimensions of the vehicle frame 100, the curve radius, and the driving speed.

[0079] In some embodiments of this application, such as Figure 4As shown, the body frame 100 also includes at least four lifting lugs 180, which face outwards and are mounted on the first web 131 of the crossbeam structure 140, for transporting or hoisting the body frame 100 to a designated location. It should be noted that the number of lifting lugs 180 on the body frame 100 can be four, but is not limited to four. The number and location of the lifting lugs 180 should vary depending on the design and purpose of the body frame 100, and require detailed design and calculation based on actual conditions to provide sufficient support.
