Description

Technical Field

[0001] This utility model relates to the field of tow trucks, and in particular to a European-style gantry frame for tow trucks. Background Technology

[0002] Among the many structural components of a wrecker truck, the gantry is one of the core load-bearing and operational components. Traditional wrecker trucks have various gantry structures, but some problems and limitations have gradually been exposed in actual use.

[0003] European-style gantry frames typically use high-strength steel, such as 45# steel, which has higher strength and toughness than ordinary carbon structural steel. In current technology, European-style gantry frames generally have a mounting plate designed on the top beam. When mounting a spare tire for the tow truck, the tire needs to be lifted and secured to the mounting plate through a hole on the wheel hub. Due to the tire's weight, this usually requires two people to operate. Furthermore, after mounting the tire, its weight is entirely borne by the mounting plate. On bumpy roads, the mounting plate is prone to deformation or even breakage due to vibration. Additionally, for tow trucks equipped with SCR systems, urea is an essential consumable. If the urea runs out, the vehicle's engine control module will limit power output, significantly reducing vehicle power and increasing fuel consumption, potentially even preventing normal operation. Therefore, timely replenishment of urea is necessary to ensure normal vehicle operation. Moreover, tow trucks are equipped with multiple urea tanks. Current gantry frames generally lack storage capacity, so the urea tanks are usually placed in the driver's cab, taking up considerable space and requiring special securing and positioning. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a European-style gantry for a tow truck. This gantry can quickly position and mount a spare tire. Part of the spare tire's weight is supported by the bottom beam, eliminating the need to lift it. In addition, it has a urea tank fixing component that also has a storage function, enabling quick loading of the urea tank.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a European-style gantry frame for a tow truck, comprising...

[0006] A gantry frame body, the bottom of the gantry frame body has a support base, the gantry frame body is installed on the support base, the gantry frame body includes a bottom beam, the bottom beam has a first vertical beam and a second vertical beam on both sides respectively, and a top beam is fixed to the top of the first vertical beam and the second vertical beam;

[0007] A tire fixing assembly includes a first partition and a second partition disposed on a bottom beam, the second partition being detachably connected to the bottom beam, and a positioning structure for positioning the tire hub is also fixed on the top beam.

[0008] A urea tank fixing assembly is fixed to the side of a first upright beam. The assembly includes a supporting base plate and a mounting plate, and a limit rod is fixed between the first upright beam and the mounting plate.

[0009] Furthermore, a support column is fixed on the bottom beam, and the top of the support column is fixedly connected to the support base plate.

[0010] Furthermore, the positioning structure is a mounting plate fixed on the top beam, and the mounting plate has at least two connecting holes that match the round holes on the wheel hub.

[0011] Furthermore, the side of the bottom beam also has an extension plate with a snap-fit ​​groove, and the second partition plate is inserted into the snap-fit ​​groove. The second partition plate has snap-fit ​​protrusions on both sides.

[0012] Furthermore, the bottom of the mounting plate has an arc-shaped plate, and the arc-shaped plate has the connection hole.

[0013] Furthermore, a reinforcing rib is fixed to the back of the mounting plate, and a reinforcing rib is also fixed to the bottom of the extension plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The gantry frame can be positioned without lifting the tires by setting up the tire fixing components. At the same time, most of the weight of the tires is supported by the bottom beam, so the mounting plate will not deform when passing through bumpy or shaking roads.

[0016] 2. Since the second partition is connected to the bottom beam through a snap-fit ​​groove, the second partition can be removed first when positioning and mounting the tires, making it easier to push the tires onto the bottom beam, effectively saving manpower.

[0017] 3. An arc-shaped plate is installed at the bottom of the mounting plate. Multiple connection holes can be made according to the needs of the wheel hub. The tire and wheel hub are fastened through multiple connection holes, making the tire more stable when it is positioned by the wheel hub. Attached Figure Description

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0023] like Figures 1 to 3 The diagram shows a European-style gantry frame for a tow truck, including...

[0024] A gantry frame body 1, the bottom of the gantry frame body 1 has a support base 2, the support base 2 is mounted on the gantry frame body 3, the gantry frame body 3 includes a bottom beam 4, the bottom beam 4 has a first vertical beam 5 and a second vertical beam 6 on both sides respectively, and a top beam 7 is fixed on the top of the first vertical beam 5 and the second vertical beam 6.

[0025] A tire fixing assembly includes a first partition 8 and a second partition 9 disposed on a bottom beam 4. The second partition 9 is detachably connected to the bottom beam 4. A positioning structure for positioning the tire 14 and the wheel hub 15 is also fixed on the top beam 7.

[0026] A urea tank fixing assembly is fixed to the side of a first upright beam 5. The assembly includes a supporting base plate 10 and a mounting plate 11. A limit rod 12 is fixed between the first upright beam 5 and the mounting plate 11.

[0027] The gantry frame of this invention is mounted on the chassis of a wrecker truck via its support base 2. When the spare tire 14 needs to be mounted, the tire 14 is first pushed onto the loading platform of the wrecker truck, and then pushed forward on the loading platform until it rolls to the vicinity of the tire fixing assembly. At this point, the tire 14 is rotated 90 degrees and pushed onto the bottom beam 4, and finally rolled along the bottom beam 4 until it rolls between the first partition 8 and the second partition 9. Finally, the tire 14 is positioned by the positioning structure. In this way, since most of the weight of the tire 14 is supported by the bottom beam 4, the positioning structure will not deform even when encountering bumpy road conditions during driving. In addition, for the case where the wrecker truck needs to be equipped with urea tanks, this invention has a support base plate 21 fixed to the side of the first upright beam 5. In this way, multiple urea tanks can be fixed on the support base plate 21. Since a limit rod 12 is also fixed between the first upright beam 5 and the mounting plate 11, the urea tanks can be effectively limited and will not fall off.

[0028] Furthermore, a support column 13 is fixed on the bottom beam 4, and the top of the support column 13 is fixedly connected to the support base plate 21. Specifically, the support base plate 21 is fixed by the support column 13, which effectively improves the strength of the support base plate 21 and makes it more load-bearing.

[0029] Furthermore, the positioning structure is a mounting plate fixed on the top beam 7, and the mounting plate has at least two connecting holes 18, which match the round holes on the wheel hub 15. Specifically, the positioning structure of this utility model uses a mounting plate with at least two connecting holes 18 at its bottom, which can more securely connect to the round holes on the wheel hub 15 of the spare tire 14, making the spare tire 14 more stable when tightened. Specifically, the bottom of the mounting plate has an arc-shaped plate 16, and the arc-shaped plate 16 has the connecting holes 18, and the number of connecting holes 18 can be three.

[0030] Furthermore, the bottom beam 4 also has an extension plate on its side, in which a snap-fit ​​groove 19 is formed. The second partition plate 9 is inserted into the snap-fit ​​groove 19, and the second partition plate 9 has snap-fit ​​protrusions 20 on both sides. Specifically, since the tire tread may be relatively wide, an extension plate is provided on the side of the bottom beam to match the tire tread. In this way, the tire tread can be supported. In this utility model, the second partition plate 9 is snapped into the snap-fit ​​groove of the extension plate. In this way, the second partition plate 9 can be quickly inserted and removed. When it is necessary to fix the spare tire 14, the second partition plate 9 can be directly snapped into the snap-fit ​​groove and limited by the snap-fit ​​protrusions on both sides of the second partition plate. When it is necessary to remove the tire, the second partition plate 9 can be removed from the extension plate to avoid interfering with the removal of the tire.

[0031] Furthermore, a reinforcing rib 17 is fixed to the back of the mounting plate, and a reinforcing rib 17 is also fixed to the bottom of the extension plate 10. Specifically, to enhance the strength of the mounting plate, a reinforcing rib 17 is fixed to the back of the mounting plate, further improving its strength and preventing deformation or bending on bumpy roads. In addition, a reinforcing plate is also fixed to the bottom of the extension plate 10, which can enhance the load-bearing capacity of the extension plate and prevent it from deforming.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
