The implementation of the present invention will be described in detail below in conjunction with specific embodiments.

Referring to Figures 1-3, a preferred embodiment of the present invention is provided.

A self-lifting horizontal drilling rig for easy installation of drilling tools, including a bracket structure, the lower end of which is fixed on the horizontal drilling rig, which includes a beam 200 and a lifting mechanism 210, the beam 200 is located on the top of the bracket structure, along the horizontal drilling rig In the length direction, the beam 200 completely covers the top of the horizontal drilling machine, and one end extends out of the horizontal drilling machine, that is, the part directly below the part of the beam 200 extending out of the horizontal drilling machine is the ground. The drilling tool is lifted. The lifting mechanism 210 is connected on the beam 200, and can move freely along the length direction of the beam 200, and is used to lift the drilling tool. Specifically, the lifting mechanism 210 can be some lifting equipment such as an electric hoist. 200 can be understood as a lifting mechanism 210 as a device that moves as a guide rail and can lift objects. As for the bracket structure, it can be understood that any structure that has a beam 200 horizontally arranged above the horizontal drilling machine and has other structures to support the beam 200 and form a fixed structure with the horizontal drilling machine can be understood as a bracket structure.

The self-lifting horizontal drilling rig that is convenient for installing drilling tools provided in this embodiment adds a bracket structure on the basis of the original horizontal drilling rig. The bracket structure has a beam 200 that is horizontal above the horizontal drilling rig, and the beam 200 is connected to There is a hoisting mechanism 210 that can move along its length, so that when the drilling tool needs to be installed, the hoisting mechanism 210 is moved to the end of the crossbeam 200 that extends out of the horizontal drilling machine, that is, position 1 in Fig. 1, and the hoisting mechanism is put down The hook in 210 or other structures that can lift the drilling tool will lift the drilling tool that was originally placed on the ground. After the drilling tool is hoisted, the lifting mechanism 210 can be moved to drive the drilling tool to move. When the drilling tool is moved to When directly above the station, that is, position 2 in Figure 1, put down the drilling tool to complete the assembly of the drilling tool. Such a structural setting enables the horizontal drilling rig to complete the installation of the drilling tool by itself without using other tools, which saves the process of building the hanger, is not limited by the site, greatly saves manpower and material resources, and shortens the working hours.

In the actual use process, when a bracket structure is set on the horizontal drilling machine, the overall height of the horizontal drilling machine will increase, which is inconvenient to move the horizontal drilling machine. In order to solve this defect, in this embodiment, the bracket The structure also includes a lifting mechanism. The lifting mechanism is used to change the vertical height of the crossbeam 200. In practice, the crossbeam 200 is the upper limit position of the bracket structure. At the same time, the height of the entire support structure can be adjusted, and then the height of the entire horizontal drilling rig can be adjusted. Such a structure solves the problem that the horizontal drilling rig is too high and inconvenient to transport. When in use, the lifting mechanism rises to install the drilling tool, and when the utility is completed, the lifting mechanism descends. Of course, there is no restriction on the detailed features of the lifting mechanism, because it should be understood that any mechanism that can realize the lifting of the beam 200 can be understood as a lifting mechanism.

As for the lifting mechanism, in this embodiment, the lifting mechanism includes eight vertically arranged telescopic legs 100, and four telescopic legs 100 are respectively arranged on the front and rear sides of the horizontal drilling machine. 100 are respectively arranged in pairs, the lower ends of the telescopic outriggers 100 are fixedly connected with the horizontal drilling machine, and the upper ends of the corresponding two telescopic outriggers 100 are connected with vertical beams 110, that is, there are four vertical beams 110 in total, and the crossbeams 200 are respectively connected with The four vertical beams 110 are vertically connected, and the telescopic legs 100 can be stretched up and down. When the telescopic legs 100 stretch up and down, the crossbeam 200 will move together, so that the purpose of the crossbeam 200 moving up and down is well realized.

In this embodiment, in order to allow the lifting mechanism to have better stability, the top of each telescopic outrigger 100 is connected to the middle part of the telescopic outrigger 100 adjacent to it with a steel wire rope 300, as shown in Figure 1 , forming a cross-connected structure using wire ropes 300. The wire ropes 300 give the telescopic outrigger 100 a downward force, and the telescopic outrigger 100 itself has an upward force. The two forces balance each other, so that the telescopic outrigger 100 is in the working state more stable.

In order to make the support structure more stable as a whole, in this embodiment, oblique ribs 120 are connected between the telescopic legs 100 and the vertical beams 110, and a triangular structure is formed between the oblique ribs 120, the vertical beams 110 and the telescopic legs 100, so that The structure is more stable, and the danger of the support structure falling sideways is not easy to occur.

In this embodiment, the telescopic outrigger 100 includes a pipe sleeve and a telescopic oil cylinder arranged in the pipe sleeve. The pipe sleeve includes a telescopic outer tube and a telescopic inner tube with one end inserted in the telescopic outer tube. The telescopic outer tube and the telescopic inner tube are respectively It is connected with both ends of the telescopic oil cylinder, so that the expansion and contraction of the telescopic oil cylinder shortens the overall side length of the pipe sleeve, which in turn changes the overall length of the telescopic outrigger 100. The structure of the pipe sleeve makes the overall rigidity of the telescopic outrigger 100 Higher, capable of resisting greater bending moments.

In this embodiment, the telescopic outrigger 100 also includes a tightening device fixed on the telescopic outer tube. The tightening device is used to lock the telescopic inner tube so that the positions of the telescopic outer tube and the telescopic inner tube are relatively fixed. When the length reaches a predetermined value, the telescopic outer tube and the telescopic inner tube can be locked and fixed by the tightening device, so that the telescopic outrigger 100 can have a more stable working state.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the protection of the present invention. within range.
