Detailed implementation manners

[0023] The following are specific embodiments of the present utility model and in combination with the accompanying drawings, the technical solutions of the present utility model are further described, but the present utility model is not limited to these embodiments.

[0024] Embodiment 1:

[0025] An oil pipeline crane, as Figures 1 to 4 shown, includes a base 1, a slewing bearing seat 2 is arranged on the base 1, a tower body 3 is installed on the slewing bearing seat 2, a boom 4 is installed on the tower body 3 through a hinge, and an oil cylinder 5 is installed between the tower body 3 and the boom 4. Specifically, one end of the oil cylinder 5 is rotatably connected to the tower body 3, and the output end of the oil cylinder 5 is rotatably connected to the boom 4.

[0026] At least two oil pipelines 6 are arranged inside the boom 4, the ends of the two oil pipelines 6 both extend out of the boom 4, the ends of the two oil pipelines 6 are bent in opposite directions respectively, and flanges 7 are arranged at the ends of the two oil pipelines 6.

[0027] A slewing joint 8 is arranged inside the base 1, at least two connecting pipelines 9 are rotatably connected to the slewing joint 8, the two connecting pipelines 9 are respectively communicated with the two oil pipelines 6, and at least two connecting pipes are arranged on the slewing joint 8. In this embodiment, the two connecting pipes include a right-angle pipe 10 and a straight pipe 11, and the right-angle pipe 10 and the straight pipe 11 are respectively located on both sides of the slewing joint 8.

[0028] It should be noted that in this embodiment, the internal structure of the slewing joint 8 is similar to the internal structure of the slewing joint 8 of the double oil pipeline crane disclosed in the Chinese patent with the publication number of CN203258253U, which belongs to the prior art. Therefore, the internal structure of the slewing joint 8 and how to realize the slewing of the two connecting pipelines 9 will not be elaborated too much.

[0029] It should be noted that the oil products can be simultaneously transported through the two connecting pipelines 9 and the two oil pipelines 6 respectively, so as to increase the transportation volume of the oil products and further improve the transportation efficiency of the oil products.

[0030] There are two lugs 12 provided on the rotary joint 8, and hanging holes 13 are provided on both of the two lugs 12, so that the rotary joint 8 can be hoisted by a hoisting tool, thereby facilitating the transportation and installation of the rotary joint 8.

[0031] A winch 14 and a pulley 15 are provided on the boom 4. A steel wire rope 16 is provided on the winch 14. The steel wire rope 16 bypasses the pulley 15, and the end of the steel wire rope 16 is connected with a counterweight 17. A hook 18 is provided on the counterweight 17.

[0032] An angle indicator 19 is provided on the boom 4. An operator can know the angle when the boom 4 moves from the angle indicator 19, so as to realize the precise positioning of the boom 4.

[0033] A guardrail 20 is provided on the boom 4. The guardrail 20 is arranged along the length direction of the boom 4. Protection is carried out through the guardrail 20 to improve safety.

[0034] A floodlight 21 is provided on the boom 4. The floodlight 21 is close to the hook 18. In an environment with insufficient light, the floodlight 21 can illuminate the hook 18 and the working area below it, reduce blind spots, and improve the overall visibility of the working area.

[0035] Embodiment Two:

[0036] The difference between Embodiment Two and Embodiment One is that, as Figure 5 shown, a support diagonal rod 22 is provided on the tower body 3. The end face of the support diagonal rod 22 can abut against the outer side wall of the boom 4. It should be noted that when the boom 4 is in a horizontal state, at this time the end face of the support diagonal rod 22 abuts against the outer side wall of the boom 4, so as to support the boom 4 and improve the stability of the boom 4. Moreover, when the oil cylinder 5 fails and causes the boom 4 to lose the main support, the support diagonal rod 22 can prevent the boom 4 from falling, and can effectively improve safety.

[0037] A reinforcing rod 23 is provided between the middle of the support diagonal rod 22 and the tower body 3. The support diagonal rod 22, the tower body 3 and the reinforcing rod 23 cooperate to form a triangular structure, so that the overall structure is more stable and further enhances the supporting effect of the support diagonal rod 22 on the boom 4.

[0038] The specific embodiments described herein are only examples to illustrate the spirit of the present invention; those skilled in the technical field to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
