Description

Technical Field

[0001] The utility model relates to the field of oil and natural gas drilling, in particular to a flagpole sliding rail type lifting frame. Background Art

[0002] In the field of oil and gas drilling, the flagpole sliding rail crane of the K-type derrick occupies a smaller overhead crane area than the conventional truss crane, has a compact structure, and a small transportation size. It is especially suitable for derricks with small overhead crane areas and special lifting methods.

[0003] The simplified design of the lifting frame ensures structural strength while maintaining complete functions and being lighter, which reduces the weight of the derrick and lowers the lifting load, and is of great significance to the lightweight design of the derrick and energy conservation and environmental protection.

[0004] The existing truss-type crane has many inconveniences when used on derricks with small overhead crane platforms and multiple required functions, and may affect the normal installation of the derrick. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a flagpole sliding rail lifting frame which is light, fully functional and does not affect the lifting.

[0006] The technical solution adopted by the utility model is: a flagpole sliding rail type lifting frame, which is characterized in that: it includes a column and a guide rail, the guide rail is fixedly arranged at the upper end of the column, one end of the guide rail is vertically fixed to the column, and the other end extends horizontally; a hoist trolley is provided on the guide rail, and an oblique support is provided between the end of the guide rail and the top of the column; the bottom of the guide rail is provided with a connecting bracket connected to the derrick.

[0007] Preferably, a sight height lamp holder is provided on the inclined support.

[0008] Preferably, a lightning rod seat is provided on the inclined support.

[0009] Preferably, the bottom of the guide rail is rotatably arranged on the connecting bracket through a sleeve and a limiting tube.

[0010] The beneficial effects achieved by the utility model are:

[0011] 1. Light structure: simple structure and light weight;

[0012] 2. Complete functions: the main body can rotate and the trolley can slide in the guide rail to ensure that it can be hoisted to each pulley group;

[0013] 3. Save space: It does not occupy too much overhead crane platform, and the staff has a larger range of activities;

[0014] 4. Easy to install: just connect the main body to the fixed sleeve of the overhead crane seat. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 It is a structural diagram of the utility model;

[0016] In the figure: 1- casing; 2- limiting tube; 3- column; 4- guide rail; 5- sight height lamp holder; 6- lightning rod holder; 7- connecting bracket; 8- hoist trolley; 9- inclined support. DETAILED DESCRIPTION

[0017] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0018] like Figure 1 As shown, the utility model is a flagpole sliding rail crane, including a column 3 and a guide rail 4. The column 3 and the guide rail 4 are integrally formed into a flagpole structure. The guide rail 4 is fixedly arranged at the upper end of the column 1, one end of the guide rail 4 is vertically fixed to the column 3, and the other end extends horizontally; a hoist trolley 8 is provided on the guide rail 4, and an oblique support 9 is provided between the end of the guide rail 4 and the top of the column 3; a connecting bracket 7 connected to the derrick is provided at the bottom of the guide rail 4.

[0019] In this embodiment, a sight height lamp holder 5 is provided on the inclined support 9, and a warning light is installed on the sight height lamp holder 5 for high-altitude warning.

[0020] In this embodiment, a lightning rod seat 6 is provided on the oblique support 9, and a lightning rod is installed on the lightning rod seat 6 for overall lightning protection of the derrick.

[0021] In this embodiment, the bottom of the guide rail 4 is rotatably disposed on the connecting bracket 7 through the sleeve 1 and the limiting tube 2 .

[0022] In this embodiment, the columns 3 are made of round tubes, and the guide rails 4 are made of I-beams.

[0023] In this embodiment, the hand hoist trolley 8 arranged on the I-beam guide rail 4 can slide within the range of the guide rail 4; the sleeve 1 and the limit tube 2 are rotatably connected with the connecting bracket 7, so that the lifting frame can be rotated as a whole, making the lifting frame's operating area wider, and the lifting frame can be equipped with a hydraulic rotation mechanism to realize automatic rotation.

[0024] It should be noted that the above description of the technical solution is illustrative only. This specification may be embodied in various forms and should not be construed as limiting the technical solution set forth herein. Rather, these descriptions are provided to ensure that the disclosure of this utility model is thorough and complete and to fully convey the scope of this disclosure to those skilled in the art. Furthermore, the technical solution of this utility model is limited only by the scope of the claims.
