[0029] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0030] In response to the deficiencies or one of the deficiencies raised in the above-mentioned background technology, an embodiment of the present application provides a universal supporting tooling for transporting pipe segments and box culverts, which can be used as a pipe segment bracket to assist in transporting pipe segments, and can also be used as a box culvert bracket to assist in transporting box culverts, making it convenient for transport vehicles to quickly switch between transporting pipe segments and box culverts, thereby improving transportation efficiency.

[0031] See also Figures 1 to 5 As shown, the embodiment of the present application provides a universal support tool for transporting segments and box culverts, including:

[0032] The support seat 100 has a first support surface 101 and a second support surface 102 on its top surface. The transverse cross-section of the first support surface 101 and the transverse cross-section of the second support surface 102 are both arc-shaped and the centers of the circles are both located obliquely above the support seat 100. The radius of the first support surface 101 is smaller than the radius of the second support surface 102.

[0033] The top surface of the support seat 100 of the universal support tooling of the embodiment of the present application is provided with a first support surface 101 and a second support surface 102. Since the radius of the first support surface 101 is smaller than the radius of the second support surface 102, the first support surface 101 can be used to support the transportation of pipe segments, and the second support surface 102 can be used to support the transportation of box culverts, thereby facilitating the transport vehicle to quickly switch between the transportation of pipe segments and box culverts, thereby improving transportation efficiency.

[0034] In addition, since the support seats 100 need to be used in pairs to support both sides of the pipe segment or box culvert, the centers of the transverse cross-sections of the first support surface 101 and the second support surface 102 are both located obliquely above the support seat 100. When the support seats 100 on both sides are arranged separately, the centers of the circles are located in the middle of the support seats 100 on both sides to achieve stable support of the pipe segment or box culvert.

[0035] For example, during use, the support bases 100 are symmetrically fixed on a transport vehicle, with the center of the support surfaces on each side of the support base 100 falling between the two support bases 100. When transporting a segment, the first support surfaces 101 on each side of the support base 100 support the segment; when transporting a box culvert, the second support surfaces 102 on each side of the support base 100 support the box culvert.

[0036] Furthermore, in order to effectively utilize the support surface on the top of the support seat 100 and ensure the stability of the pipe segments and box culverts during switching and transportation, the first support surface 101 and the second support surface 102 are arranged adjacent to each other, and the surface areas of the first support surface 101 and the second support surface 102 are basically the same.

[0037] It should be noted that since the radius of the outer surface of the pipe segment is usually smaller than the radius of the bottom surface of the box culvert, by setting two support surfaces with different radii, the supporting tooling of the present application can be used as a pipe segment bracket to assist in transporting the pipe segments, and can also be used as a box culvert bracket to assist in transporting the box culvert, which facilitates the transport vehicle to quickly switch between transporting pipe segments and box culverts and improves transportation efficiency.

[0038] In some alternative embodiments: See Figures 1 to 5 As shown, an embodiment of the present application provides a universal supporting tool for transporting pipe segments and box culverts. The universal supporting tool for transporting pipe segments and box culverts also includes a fixing seat 200, and the supporting seat 100 is detachably connected to the fixing seat 200.

[0039] The universal support fixture of the embodiment of the present application further includes a fixing base 200 for fixed installation on a transport vehicle. The support base 100 and the fixing base 200 are detachably connected to facilitate installation or removal of the support base 100. For example, the fixing base 200 is fixedly mounted on the transport vehicle by welding. When the pipe segment or box culvert needs to be transported, the support base 100 is mounted on the fixing base 200. The support base 100 and the fixing base 200 can be detachably connected by bolts or snaps.

[0040] In some alternative embodiments: See Figures 1 to 5 As shown, an embodiment of the present application provides a universal support tooling for transporting pipe segments and box culverts, wherein the support base 100 of the universal support tooling for transporting pipe segments and box culverts is inserted into the fixing base 200, and a pin shaft 300 passing through the fixing base 200 is inserted into the support base 100.

[0041] The support base 100 of the universal support tooling of the embodiment of the present application is installed on the fixed base 200 by means of a plug-in sleeve. At the same time, a pin shaft 300 passing through the fixed base 200 is inserted on the support base 100, and a detachable connection is achieved between the support base 100 and the fixed base 200 through the pin shaft 300.

[0042] Exemplarily, the bottom end of the support seat 100 is open, and the support seat 100 can be directly inserted into the fixed seat 200 in the vertical direction. After the support seat 100 is inserted into the fixed seat 200, the installation pin 300 passes through the support seat 100 and the fixed seat 200 to prevent the support seat 100 from separating from the fixed seat 200.

[0043] In some alternative embodiments: See Figures 1 to 5 As shown, an embodiment of the present application provides a universal support tooling for transporting pipe segments and box culverts, wherein the pin shaft 300 of the universal support tooling for transporting pipe segments and box culverts has an end head 310 for abutting the support seat 100, and a stop block 103 for stopping the end head 310 is installed on the support seat 100.

[0044] The pin shaft 300 of the universal support tooling of the embodiment of the present application has an end head 310. After the pin shaft 300 passes through the support seat 100 and the fixed seat 200, the end head 310 abuts against the wall surface of the support seat 100. In order to prevent the pin shaft 300 from detaching from the support seat 100 during transportation, a stop block 103 is installed on the support seat 100. One end of the stop block 103 extends to the front end of the end head 310, which can prevent the pin shaft 300 from slipping off the support seat 100.

[0045] Exemplarily, the stop block 103 is L-shaped and is fastened to the side wall of the support seat 100 by bolts. When a pin shaft 300 needs to be passed through the support seat 100 to pass through the fixing seat 200, the bolts are loosened and the stop block 103 is swung to avoid the pin shaft 300. When the pin shaft 300 is installed in place, the end head 310 abuts against the wall surface of the support seat 100. The stop block 103 is then reset and the bolts are tightened. One end of the stop block 103 extends to the front end of the end head 310 to stop the pin shaft 300.

[0046] It should be noted that in this embodiment, the stopper 103 is connected to the support base 100 via a single bolt, which is located directly above the mounting position of the pin 300. The stopper 103 can rotate relative to the bolt. When removing the pin 300, the stopper 103 only needs to be rotated to avoid the end 310 of the pin 300 to remove the pin 300 from the support base 100. In addition, after the pin 300 is installed, the stopper 103 can naturally droop under the action of gravity, blocking the end 310 of the pin 300, thereby preventing the pin 300 from separating from the support base 100.

[0047] In some alternative embodiments: See Figures 1 to 5 As shown, an embodiment of the present application provides a universal support tooling for transporting pipe segments and box culverts. The support base 100 of the universal support tooling for transporting pipe segments and box culverts includes a hollow column 110 formed by welding steel plates, and a cover plate 120 fixed to the top of the hollow column 110. The cover plate 120 has a first support surface 101 and a second support surface 102. The hollow column 110 is provided with a through hole 111 for the pin shaft 300 to penetrate.

[0048] The universal support fixture of this embodiment comprises a support base 100 comprising a hollow column 110 with upper and lower openings. A cover plate 120 is welded to the top of the hollow column 110, sealing the upper opening. The cover plate 120 includes a first support surface 101 and a second support surface 102, respectively supporting the segments and the box culvert. For example, in this embodiment, the hollow column 110 is formed by welding four steel plates together, forming a rectangular cross-section.

[0049] In addition, the lower end of the hollow column 110 is open, which makes it convenient for the hollow column 110 to be inserted into the fixing seat 200. Cooperating with the through hole 111 opened on the hollow column 110, it is convenient to insert the pin shaft 300 through the through hole 111 on the hollow column 110 to pass through the fixing seat 200 after the hollow column 110 is inserted into the fixing seat 200.

[0050] In some alternative embodiments: See Figures 1 to 5As shown, an embodiment of the present application provides a universal support tooling for transporting pipe segments and box culverts. The support base 100 of the universal support tooling for transporting pipe segments and box culverts also includes a reinforcing plate 130 fixed inside the hollow column 110, and an annular plate 140 fixed to the bottom end of the hollow column 110.

[0051] The hollow column 110 of the support base 100 of the universal support fixture of the present embodiment is further fixedly mounted with a reinforcement plate 130 to enhance the strength of the support base 100. Furthermore, the support base 100 also includes an annular plate 140 fixed to the bottom end of the hollow column 110. This annular plate 140 facilitates support on a transport vehicle and enhances the strength of the bottom end of the support base 100.

[0052] For example, in this embodiment, the hollow column 110 is formed by welding four steel plates and has a rectangular cross-section. The reinforcing plate 130 is rectangular and the four sides are welded and fixed to the walls of the four steel plates. At the same time, the top surface of the annular plate 140 is welded and fixed to the bottom ends of the four steel plates, which does not affect the insertion of the hollow column 110 into the fixing seat 200. At the same time, the annular plate 140 can be supported on the transport vehicle to prevent the shear pin 300 when the hollow column 110 is under pressure.

[0053] In some alternative embodiments: See Figures 1 to 5 As shown, an embodiment of the present application provides a universal support tooling for transporting pipe segments and box culverts. The fixed base 200 of the universal support tooling for transporting pipe segments and box culverts includes a frame 210 formed by welding steel plates, and a guide bar 220 fixed to the frame 210 and used to guide the support base 100. The frame 210 is provided with a through hole 211 for the pin shaft 300 to pass through.

[0054] The fixing base 200 of the universal support fixture of the embodiment of the present application is formed by welding four steel plates to form a frame 210. Guide bars 220 are installed on the side walls of the frame 210. The guide bars 220 facilitate the insertion of the support base 100 into the frame 210 and cooperate with the through holes 211 provided on the frame 210 to facilitate the pin 300 installed on the support base 100 to pass through the frame 210 through the through holes 211. Furthermore, the guide bars 220 are symmetrically arranged and chamfered at the top to facilitate the sliding of the support base 100 along the surface of the guide bars 220 to achieve the insertion of the support base 100 into the frame 210.

[0055] In some alternative embodiments: See Figures 1 to 5 As shown, an embodiment of the present application provides a universal support tooling for transporting pipe segments and box culverts. The fixing base 200 of the universal support tooling for transporting pipe segments and box culverts also includes a guide cylinder 230 fixed in the frame 210, and the two ends of the guide cylinder 230 are respectively connected to the through holes 211 on both sides.

[0056] The fixed seat 200 of the universal support tooling of the embodiment of the present application also includes a guide cylinder 230 fixed in the frame 210. The guide cylinder 230 is fixedly installed by welding. The two ends of the guide cylinder 230 are respectively connected to the through holes 211 on both sides of the frame 210. The guide cylinder 230 is used to guide the pin shaft 300, so that the pin shaft 300 can pass through the through holes 211 on both sides. At the same time, the guide cylinder 230 can also increase the overall structural strength of the fixed seat 200 and improve the connection stability between the fixed seat 200 and the support seat 100.

[0057] In some alternative embodiments: See Figures 1 to 5 As shown, an embodiment of the present application provides a universal support tooling for transporting pipe segments and box culverts, and a buffer pad 400 covering a first support surface 101 and a second support surface 102, as well as a baffle 500 for preventing the buffer pad 400 from falling off, are fixed on the support seat 100 of the universal support tooling for transporting pipe segments and box culverts.

[0058] A buffer pad 400 covering the first support surface 101 and the second support surface 102 is fixed on the support seat 100 of the universal support tooling of the embodiment of the present application, which can effectively protect the surface of the pipe segment. At the same time, a baffle 500 is fixed on the support seat 100, and the baffle 500 can block the end of the buffer pad 400 to prevent the buffer pad 400 from falling off from the installation side of the baffle 500.

[0059] Exemplarily, the buffer pad 400 can be made of a rubber plate and fixed to the top surface of the cover plate 120 by bonding, and the ends of the first support surface 101 and the second support surface 102 away from each other are both welded with a blocking bar 500 that contacts the buffer pad 400.

[0060] In some alternative embodiments: See Figures 1 to 5 As shown, an embodiment of the present application provides a universal support tool for transporting pipe segments and box culverts. Two lifting ears 600 are symmetrically provided on the support base 100 of the universal support tool for transporting pipe segments and box culverts, and a lifting hole 610 is provided on the lifting ear 600.

[0061] The universal support tooling of the embodiment of the present application has lifting ears 600 welded on the two opposite side walls of the support base 100. The lifting ears 600 on both sides are symmetrically arranged, and lifting holes 610 are opened on the lifting ears 600, which are convenient for connecting the lifting ears 600 on both sides with external lifting ropes to realize vertical lifting of the support base 100.
