[0004] The bottom edge 3 of the cab shell is flush with the frame mounting surface 4 of the mounting supports, and the four mounting supports are completely surrounded by the cab shell from above and around and are not exposed; in addition, there are more tubes at the bottom of the cab. The lower part, the front, rear, left, and right directions are adjacent to the relevant structures of the frame; when the cab is actually installed, the above 2 groups of 4 mounting supports will be blocked by the adjacent structures and the operating space will be blocked. When the selection direction is limited and the fastener installation operation is difficult

Embodiment
[0041] The concrete size of mounting support of the present invention can be set as follows:
[0042] The diameter of the central mounting hole 50 of the first mounting plate 20 or the second mounting plate 30 is 11-18mm, which is determined by increasing the nominal diameter of the bolt by 1mm-3mm;
[0043] The inner diameter of the cylindrical support body 10 is 55-75 mm, the wall thickness of the cylindrical support body 10 is 8-12 mm, and the height of the cylindrical support body 10 is 25-120 mm;
[0044] The diameter of the first mounting plate 20 or the second mounting plate 30: according to the outer diameter of the cylindrical support body 10 increased by 8-12 mm; the thickness of the first mounting plate 20 or the second mounting plate 30 is: 8-12 mm;
[0045] The opening angle of the operation port 40 is 110°±25°.
[0046] The cylindrical support body 10, the first mounting plate 20 and the second mounting plate 30 can be made of common Q235 or Q345 steel plates an...

The invention discloses a mounting support for a cab of an oil workover rig, comprising a cylindrical support body; a first mounting plate and a second mounting plate are respectively mounted at the openings at both ends of the cylindrical support body, mounting holes are arranged at the centers of the first mounting plate and the second mounting plate, and operation openings are axially opened onthe side walls of the cylindrical support body. The mounting bracket of the invention is of an axially symmetrical structure, The invention can arbitrarily adjust the axial mounting angle, and is notlimited to the front-rear and left-right directions, so that the opening is easy to mount and operate, the direction with the operation gap is easy to produce and process, the cost is equivalent to the original structure, the mounting strength and the aesthetics can be improved, and the defects of the original structure in the mounting process are effectively solved.
Description
technical field [0001] The invention relates to the technical field of a self-propelled petroleum workover rig and a special vehicle, in particular to a mounting support for a cab of a petroleum workover rig. Background technique [0002] The self-propelled oil workover rig usually adopts an offset cab, and the front and rear rows of the cab are longitudinally aligned with a total of four fixed points installed on the frame assembly. [0003] like Figure 1~4 As shown, the conventional installation structure is mostly corresponding to the design of two sets of installation supports 1. The installation support 1 is a rectangular frame structure as a whole. The support 1 is composed of a welded and fixed door-line bending plate 5 and a bottom plate 6. The door-line bending plate 5 is used to install fasteners connecting the offset cab 2, and the bottom plate 6 is used to install fasteners connected to the vehicle frame. Firmware; the height dimension of the 2 sets of mounting...
