Problems solved by technology
[0002] At present, it is common for semi-trailers to be parked without a tractor, and the front hydraulic cylinder or hydraulic outrigger support is often used, and the rear is supported by a leaf spring axle. The whole vehicle cannot rotate around the axle, and the frame cannot be placed. On the level ground, the force on the frame is uneven, the stress is concentrated, the frame is prone to deformation, and the service life of the frame is greatly reduced.

Embodiment
[0015] Example: such as Figure 1-3 As shown, a drill rod and drilling tool semi-trailer includes a frame 5, the frame 5 includes a fixed connecting frame 7 at the front end, a frame body 8 of the landable part, and a frame tail 9 for setting the rear wheels of the trailer, The frame body 8 is a plane structure that can be in full contact with the ground. The frame tail 9 is set higher than the plane of the frame body 8 through the connecting part 10; two hydraulic cylinders 3 are vertically symmetrically arranged on the fixed connecting frame 7 and arranged at the same time The fixing device used for fixing with the tractor 1 is the traction pin 2 and the pin hole provided on the fixed connecting frame 7 and the tractor 1. Of course, other connection methods are also possible. A double-balanced beam rigid bridge 6 is arranged under the rear part 9 of the frame, and a drill pipe discharge box 4 is arranged on the main body of the frame.

The invention discloses a drill rod and drilling tool semi-trailer. The semi-trailer comprises a frame, wherein the frame comprises a fixed connecting frame at a front end, a frame main body of a landing part on the middle part and a frame tail part at a rear end for arranging a trailer rear wheel; the frame main body has a planar structure which can be completely contacted with the ground; the frame tail part is higher than the plane of the frame main body through a connection part; the fixed connecting frame is provided with a fixing device connected with a tractor and vertically provided with a hydraulic oil cylinder; a double balanced beam rigid bridge is arranged below the tail part of the frame; and the frame main body is provided with a drill rod discharge box. The semi-trailer hasthe advantages of greatly improving the transportation efficiency, reducing the cost during the transportation, landing with the entire frame without being supported by the front part under the condition of no tractor to ensure more uniform stress, greatly reducing the stress concentration, prolonging the service life and ensuring novel structure, convenient parking and simple and practical structure.
Description
Technical field [0001] The invention relates to a carrying device used in the exploration and development of petroleum resources, in particular to a new type of special semi-trailer for carrying drill pipes and drilling tools. Background technique [0002] At present, common semi-trailers are parked without a tractor. Most of them are supported by hydraulic cylinders or hydraulic outriggers at the front and supported by leaf spring axles at the rear. The whole vehicle cannot be rotated around the axle and the frame cannot be placed. On a level ground, the force of the frame is uneven, the stress is concentrated, and the frame is prone to deformation, which greatly reduces the service life of the frame. Summary of the invention [0003] The purpose of the present invention is to provide a drill rod and drill tool semi-trailer, which can improve transportation efficiency and prolong the service life of equipment. [0004] In order to achieve the above objective, the present invention...
