Technical Field
[0001] The utility model relates to the technical field of oil field cranes, in particular to an oil field crane base. Background Art
[0002] A crane generally refers to a multi-action lifting machine that can lift heavy objects vertically and carry them horizontally within a certain range. In oilfield lifting operations, fixed cranes are generally used. The support column of an existing crane is generally fixed directly to the base through a flange. However, due to the heavy weight of the lifting objects of an oilfield crane, the connection between the support column and the base has higher requirements. Utility Model Content
[0003] Purpose of the utility model: The utility model provides an oilfield crane base, which can firmly limit the support column of the oilfield crane on the base.

[0005] An oilfield crane base comprises a supporting bottom pile, the bottom of the supporting bottom pile is located under the ground, a first fixing flange is welded on the supporting bottom pile, a limiting sleeve is fixed on the first fixing flange, and the limiting sleeve is fixed on the first fixing flange through a second fixing flange;
[0006] A plurality of connection blocks are fixed on the peripheral side of the limiting sleeve, an L-shaped support plate is fixed on the connection block, and a limiting clamp ring is connected below the L-shaped support plate;
[0007] The limiting clamp ring is clamped under a plurality of limiting plates, and a supporting column is arranged inside the limiting sleeve.
[0008] As an improvement: a plurality of first threaded holes are provided on the limit plate, and the first threaded holes extend inwardly to support the interior of the bottom pile.
[0009] As an improvement: a plug-in slot is provided on the support bottom pile at a position opposite to the support column, and the support bottom pile can be inserted into the plug-in slot.
[0010] As an improvement: a plurality of second threaded holes are evenly arranged on the support column.
[0011] As an improvement: a threaded docking hole is provided on the limiting sleeve at a position opposite to the second threaded hole, and a docking pad is provided on the outer wall of the limiting sleeve at a position opposite to the threaded docking hole.
[0012] As an improvement: the support column can be inserted and fixed inside the limiting sleeve through the second threaded hole and the threaded docking hole.
[0013] In summary, the utility model has the following beneficial effects:
[0014] 1. The support column can be inserted into the inner part of the limiting sleeve, and the bottom of the limiting sleeve is fixed to the supporting bottom pile through the second fixing flange. At the same time, an L-shaped support plate is provided to enhance the connection firmness between the limiting sleeve and the supporting bottom pile. When the support column applies force to the limiting sleeve, the L-shaped support plate can receive part of the force and transfer it to the supporting bottom pile;
[0015] 2. The supporting bottom pile can be inserted into the inside of the plug-in through groove on the supporting bottom pile, which can further disperse the force of the supporting column on the limiting sleeve. BRIEF DESCRIPTION OF THE DRAWINGS
[0016] In order to more clearly illustrate the technical solution in the present practical embodiment, the drawings required for use in the embodiment or the description of the prior art will be briefly introduced below.
[0017] Figure 1 This is a schematic diagram of the overall structure of an oilfield crane base;
[0018] Figure 2 This is an exploded view of an oilfield crane base;
[0019] Among them: 1. Support bottom pile; 2. First fixed flange; 3. Second fixed flange; 4. Limit sleeve; 5. Connecting block; 6. L-shaped support plate; 7. Limit clamp; 8. Limit plate; 9. Support column; 10. First threaded hole; 11. Insertion groove; 12. Second threaded hole; 13. Threaded docking hole; 14. Docking pad. DETAILED DESCRIPTION
[0020] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0021] Please refer to Figure 1-Figure 2 A base of an oilfield crane comprises a supporting bottom pile 1, the bottom of the supporting bottom pile 1 is located under the ground, a first fixing flange 2 is welded on the supporting bottom pile 1, a limiting sleeve 4 is fixed on the first fixing flange 2, and the limiting sleeve 4 is fixed to the first fixing flange 2 through a second fixing flange 3; a plurality of connecting blocks 5 are fixed on the peripheral side of the limiting sleeve 4, an L-shaped supporting plate 6 is fixed on the connecting block 5, and a limiting clamping ring 7 is connected below the L-shaped supporting plate 6; the limiting clamping ring 7 is clamped below a plurality of limiting plates 8, and a supporting column 9 is provided inside the limiting sleeve 4.
[0022] In this embodiment, the support column 9 can be inserted into the inner part of the limiting sleeve 4, and the bottom of the limiting sleeve 4 is fixed to the supporting bottom pile 1 through the second fixing flange 3. At the same time, an L-shaped support plate 6 is provided to enhance the connection firmness between the limiting sleeve 4 and the supporting bottom pile 1. When the support column 9 applies force to the limiting sleeve 4, the L-shaped support plate 6 can receive a part of the force and transmit it to the supporting bottom pile.
