Description

Technical Field

[0001] The utility model relates to the technical field of workover rigs, in particular to a dual-power electric workover rig. Background Art

[0002] As a kind of well repair equipment in oil fields, workover rigs are widely used in oil field operations.

[0003] The utility model patent with patent application publication number 202222008598.1 discloses a dual-power workover rig, which relates to the technical field of workover rigs. The utility model includes a vehicle body, a first power box, a second power box, and a processing assembly. The first power box is fixedly arranged on the top side of the vehicle body, and the second power box is fixedly arranged on the top side of the vehicle body, and the second power box is adjacent to the first power box. The processing assembly is fixedly arranged on the top of the vehicle body, and the processing assembly is adjacent to the first power box and the second power box. The processing assembly includes a processing box, a bracket, an air outlet pipe, a drain pipe, a first air duct, and a second air duct. This utility model is a dual-power workover rig. By providing a processing box, a bracket, an air outlet pipe, a drain pipe, a first air duct, and a second air duct, it effectively prevents toxic and harmful gases generated by the workover rig from being discharged into the air and polluting the environment, which is in line with the concept of emission reduction and environmental protection.

[0004] However, the above device still has some shortcomings in actual use. The most obvious one is that the derrick needs to be rotated to a vertical direction and fixedly connected to the fixed rod at the bottom when in use. However, since the derrick is prone to collision with the fixed rod at the bottom during rotation, it is easy to cause collision damage over time. It is also easy to cause the derrick to be unable to maintain a completely vertical position, resulting in an angle difference between it and the fixed rod, affecting the fixing effect.

[0005] Therefore, it is necessary to invent a dual-power electric workover rig to solve the above problems. Utility Model Content

[0033] like Figure 1-Figure 3 As shown, a dual-power electric workover rig disclosed in the present invention may include: a vehicle body 1, a support assembly, a mounting assembly, a lifting assembly, a limiting assembly and other components.

[0034] like Figure 1 and Figure 2 As shown, in the present disclosure, the support assembly includes a column 3 and a second support rod 4. The column 3 is fixedly connected to the top of the vehicle body 1. The derrick 2 is rotatably arranged on the top of the column 3. The second support rod 4 is fixedly connected to one side of the column 3. The bottom end of the second support rod 4 is provided with a support block 41.

[0035] The mounting assembly includes a first fixing block 21 and a second fixing block 42. The first fixing block 21 is fixedly connected to one side of the derrick 2, and the second fixing block 42 is arranged at the top end of the second support rod 4. The first fixing block 21 and the second fixing block 42 are arranged corresponding to each other, and the inner sides of the first fixing block 21 and the second fixing block 42 are symmetrically provided with mounting holes 421.

[0036] Therefore, by setting up the derrick 2, the derrick 2 can be rotated on the outside of the column 3. When needed, the derrick 2 can be lifted up and set parallel to the column 3. By setting up the first fixing block 21 and the second fixing block 42, the inner sides of the first fixing block 21 and the second fixing block 42 are provided with mounting holes 421 for easy fixation. By setting up the support block 41, the support block 41 can be set on the ground for support, which can effectively lift up the derrick 2 for supporting work.

[0037] like Figure 2 and Figure 3 As shown, in a preferred embodiment, a first inner groove 48 and a second inner groove 49 are provided on the inner side of the second support rod 4, and the second inner groove 49 is provided above the first inner groove 48. The lifting assembly includes a slider 45 and a connecting rod 44. The slider 45 is slidably connected to the inner side of the second inner groove 49, and the connecting rod 44 is fixedly connected to the bottom end of the slider 45, and the connecting rod 44 is fixedly connected to the bottom end of the second fixed block 42.

[0038] Therefore, by setting the connecting rod 44 and the slider 45, the movement of the slider 45 can effectively drive the second fixed block 42 to move. When it needs to be used, the second fixed block 42 moves upward and is set parallel to the first fixed block 21, which is convenient for subsequent fixing work.

[0039] like Figure 2 As shown, in the present disclosure, a guide rod 46 is fixedly connected to the inner side of the first inner groove 48, and the guide rod 46 is slidably connected to the inner side of the connecting rod 44 and the slider 45. A spring 47 is provided on the outer side of the guide rod 46, and the spring 47 is provided at the bottom end of the slider 45.

[0040] Therefore, by setting the guide rod 46, the guide rod 46 can be effectively slidably connected to the inner side of the slider 45 and the connecting rod 44, effectively increasing its sliding stability. By setting the spring 47, the spring 47 is set at the bottom end of the slider 45, which can effectively lift the slider 45, that is, effectively lift the second fixing block 42, facilitating subsequent fixing work.

[0041] like Figure 2 As shown, in a preferred embodiment, through slots 43 are provided on both sides of the second support rod 4, a limiting slot 451 is provided on the inner side of the slider 45, a latch 7 is provided on the inner side of the limiting slot 451, and the latch 7 and the through slot 43 are provided corresponding to each other.

[0042] Thus, by setting the latch 7, the latch 7 can be inserted into the inner side of the slider 45 to limit the position of the diesel generator 5. Figure 2 In the embodiment, the latch 7 is inserted into the inner side of the through slot 43 at the bottom end of the second support rod 4, and the through slot 43 at this position is only on one side, which can effectively fix the slider 45. After the latch 7 is pulled out, the slider 45 moves upward under the drive of the spring 47, so that the slider 45 moves to the upper through slot 43, and then the latch 7 is inserted into the inner side of the slider 45 to limit the slider 45. Figure 3 As shown, at this time, through slots 43 are provided on both sides of the second support rod 4, which facilitates the simultaneous insertion of two latches 7 to limit and fix the slider 45, effectively increasing the fixing effect.

[0043] like Figure 1As shown, in the present disclosure, a first support rod 12 and a first fixed block 21 are symmetrically arranged at the top of the vehicle body 1, and the first support rod 12 and the first fixed block 21 are both arranged at the bottom end of the derrick 2, and a diesel generator 5 and an electric motor 6 are arranged at the top of the vehicle body 1.

[0044] Therefore, by setting the first support rod 12, the first support rod 12 can effectively support the derrick 2, and by setting the first fixing block 21, the first fixing block 21 can effectively lift the derrick 2 to facilitate subsequent fixing work. By setting the diesel generator 5 and the electric motor 6, the diesel generator 5 drives the gearbox, and after the gearbox changes speed, it is input to the working part through the gear and chain transmission. The electric motor 6 also drives the gearbox and is input to the working part through the gear and chain transmission. Both the diesel generator 5 and the electric motor 6 input power into the interlocking multi-power input distribution transmission device and drive the working part.
