Description

Technical Field

[0001] The utility model belongs to the technical field of engineering vehicle support devices, and in particular relates to an engineering vehicle support leg mounting structure. Background Art

[0002] During construction, most construction vehicles require support legs around the chassis to support the entire vehicle so that the vehicle can withstand sufficient forces. The support legs are usually set vertically and have a telescopic structure. The fixed parts of the support legs are usually set at the end of a telescopic rod in a horizontal state. The telescopic rod is passed through a horizontally set conduit. The length direction of the conduit is consistent with the width direction of the vehicle. Current support legs are usually symmetrically installed on the left and right sides of the vehicle, and a pair is provided at the front and rear ends of the vehicle. The conduit is usually passed through the inside of the vehicle chassis beam. This installation structure sets both the conduit and the telescopic rod inside the chassis, which is less convenient for installation and subsequent maintenance. Moreover, when this symmetrical installation structure is applied to a narrower vehicle chassis, the span between the paired support legs is limited because two conduits need to be arranged along the same straight line within a limited width range. After the support legs are deployed, the support stability of the vehicle is poor. Utility Model Content

[0003] In order to solve the deficiencies of the existing technology, the utility model provides a support leg mounting structure for an engineering vehicle, which is easier to assemble and the support legs have a larger span, so that the engineering vehicle has a more stable support effect.

[0004] In order to achieve the purpose of this utility model, the following scheme is proposed:

[0005] A supporting leg mounting structure for an engineering vehicle comprises upper conduits arranged horizontally on the front and rear ends of a vehicle chassis, with lower conduits arranged parallel to the lower ends of the upper conduits.

[0006] An upper guide rod is passed through the upper duct, and a lower guide rod is passed through the lower duct; the ends of the upper guide rod and the lower guide rod are respectively directed toward both sides of the chassis, and the ends of the upper guide rod and the lower guide rod are both provided with vertical support legs.

[0007] The beneficial effects of the present invention are as follows: this solution enables the lengths of the upper and lower ducts to reach the width of the vehicle chassis, so that the support legs can obtain a larger span, thereby improving the support stability of the vehicle; the upper and lower ducts are exposed to the outside of the chassis, which is more convenient for assembly and subsequent maintenance.

DETAILED DESCRIPTION

[0013] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the implementation methods of the present invention are described in detail below with reference to the accompanying drawings. However, the embodiments described in the present invention are only part of the embodiments of the present invention, rather than all the embodiments.

[0014] like Figure 1 、 Figure 2 As shown, a support leg mounting structure for an engineering vehicle includes an upper conduit 11 horizontally arranged on the front and rear ends of the vehicle chassis, and a lower conduit 12 is provided parallel to the lower portion of the upper conduit 11 .

[0015] Specifically, such as Figure 2 、 Figure 3 As shown, an upper guide rod 21 is passed through the upper conduit 11, and a lower guide rod 22 is passed through the lower conduit 12; the ends of the upper guide rod 21 and the lower guide rod 22 are respectively facing the two sides of the chassis, and the ends of the upper guide rod 21 and the lower guide rod 22 are both provided with vertical support legs 3.

[0016] This structure ensures that the length of the upper duct 11 and the lower duct 12 can reach the width of the vehicle chassis, so that the support leg 3 can obtain a larger span; and the upper duct 11 and the lower duct 12 are arranged at both ends of the vehicle chassis, directly exposing the upper duct 11 and the lower duct 12 to the outside of the chassis, with the purpose of facilitating assembly and subsequent maintenance. Although this layout will extend the overall length of the vehicle, the upper duct 11 and the lower duct 12 are arranged in an upper and lower structure, which also makes up for the deficiency of arranging the upper duct 11 and the lower duct 12 at the ends of the vehicle chassis.

[0017] Preferably, Figure 1 As shown, the upper guide tube 11 and the lower guide tube 12 are both provided with a telescopic device 13, which is used to drive the upper guide rod 21 and the lower guide rod 22 respectively; the upper guide rod 21 and the lower guide rod 22 can also be moved manually or driven by a screw; preferably, the telescopic device 13 is arranged on the outside of the upper guide tube 11 and the lower guide tube 12 to facilitate assembly and maintenance.

[0018] Preferably, the upper conduit 11 and the lower conduit 12 are connected to the chassis of the vehicle by screws.

[0019] Preferably, Figure 3 As shown, a first reinforcing rod 31 is provided on the outer side of the support leg 3 connected to the upper guide rod 21, and the first reinforcing rod 31 is provided in parallel below the upper guide rod 21, and the first reinforcing rod 31 passes parallel to the end of the lower guide tube 12, and the lower guide rod 22 is provided with a lower accommodating hole 221 for accommodating the first reinforcing rod 31, so as to reduce the size of the support leg 3 after it is folded toward the middle; a second reinforcing rod 32 is provided on the outer side of the support leg 3 connected to the lower guide rod 22, and the second reinforcing rod 32 is provided in parallel above the lower guide rod 22, and the second reinforcing rod 32 passes parallel to the end of the upper guide tube 11, and the upper guide rod 21 is coaxially provided with an upper accommodating hole 211 for accommodating the second reinforcing rod 32, so as to reduce the size of the support leg 3 after it is folded toward the middle; the above structural design can effectively improve the installation stability of the support leg 3 and improve the bearing capacity.

[0020] Preferably, the supporting leg 3 is a hydraulic cylinder structure.

[0021] Preferably, Figure 2 As shown, a clamp 4 is provided on the outside of the upper conduit 11 and the lower conduit 12 to connect the upper conduit 11 and the lower conduit 12 into an integral structure to improve the installation stability of the upper conduit 11 and the lower conduit 12. Furthermore, the clamp 4 is connected to the chassis of the vehicle.

[0022] The above description is only a preferred embodiment of the present invention and does not represent the only embodiment or limit the present invention. It should be understood by those skilled in the art that various changes or equivalent replacements made to the present invention without departing from the scope of the present invention are within the scope of protection of the present invention.
