Description

Adjustable drilling tower

Technical Field

The utility model relates to the technical field of drilling rigs, in particular to an adjustable drilling tower.

Background

For geological exploration of engineering such as civil architecture, highway, bridge and the like, a drilling machine is needed, but a vertical shaft type drilling machine is quite common in structural form, and the vertical shaft type drilling machine comprises a drilling tower, a winch for replacing a rod in the drilling process and other power assemblies. The pulley block is arranged on the top of the tower, and a cable on the winch lifts the drilling rod through the pulley.

Usually, the height of the drilling tower is fixed and is about 5-7 m, and the construction under the bridge and under the high-voltage electric tower is very limited, so that the difficulty is increased for exploration operation.

Disclosure of Invention

Aiming at a working environment with limited height, the utility model provides an adjustable drilling tower, which comprises a supporting seat, a supporting rod arranged on the supporting seat, a pulley block positioned at the top of the supporting rod and an inclined supporting rod used for reinforcing the supporting rod, wherein the supporting rod and the inclined supporting rod at least comprise three sections of detachable rod bodies, and the bottoms of the supporting rod and the inclined supporting rod are hinged with the supporting seat through double shafts so as to realize rotation in two directions.

The utility model is further provided with: a hinged support is arranged on the support seat, and a connecting block is arranged in the hinged support; the connecting block is hinged with the hinged support through a rotating shaft; the support rod is hinged with the connecting block through a pin shaft; the rotating shaft is perpendicular to the pin shaft.

The utility model is further provided with: the rod bodies are connected through flanges.

The beneficial effects of the utility model are as follows:

the technical scheme can be directly applied according to the structural style of the prior art, and the connecting block can be directly matched and connected with the support rod with the flat bottom. In addition, the disassembly of other structural components is inconvenient, and the disassembly can be realized by disassembling two nuts in the scheme, so that the disassembly is very convenient.

Detailed Description

Preferred embodiments of the present utility model are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are merely for explaining the technical principles of the present utility model, and are not intended to limit the scope of the present utility model.

Referring to fig. 1-3, the utility model provides an adjustable drilling tower, which comprises a supporting seat 4, a supporting rod 1 arranged on the supporting seat 4, a pulley block 2 arranged on the top of the supporting rod 1, and an inclined supporting rod 3 for reinforcing the supporting rod 1.

The support rod 1 and the diagonal brace 3 are provided with two. The support rod 1 and the diagonal brace 3 at least comprise three sections of detachable rod bodies, each rod body is connected through a flange, the number of the rod bodies can be increased or decreased as required between the head and the tail except for the two sections of rod bodies which can not be deleted. The rod bodies at the end and the tail can also be directly connected through flanges.

The number of rods can be adjusted in advance to change the length of the support bar 1 and the diagonal brace 3 based on different requirements of the height of the rig. However, when the length of the support bar 1 and the diagonal brace 3 is changed, the size of the support base 4 and the position of the connection point thereon are unchanged, so that the angle of the support bar 1 and the diagonal brace 3 is changed.

The top of the supporting rod 1 is hinged with the shell of the pulley block 2, and the bottom of the supporting rod is hinged with the supporting seat 4 through a double shaft so as to realize rotation in two directions. The top of the diagonal brace 3 is hinged with the support rod 1, and the bottom of the diagonal brace is hinged with the support seat 4 through double shafts so as to realize rotation in two directions.

The bottom parts of the supporting rod 1 and the diagonal brace 3 are connected with the supporting seat 4 by adopting the same structure, so the supporting rod 1 is taken as an example for illustration, and the detail is shown in fig. 2-3.

The support base 4 is provided with a hinge support 6, and a connection block 51 is provided in the hinge support 6. The connection block 51 is of a U-shaped structure. The bottom of the supporting rod 1 is in a flat structure and extends into the U-shaped opening of the connecting block 51, and the hinge joint of the supporting rod 1 and the connecting block 51 is realized through a pin shaft 53 penetrating through the connecting block 51 and the supporting rod 1. Two ends of the pin shaft 53 are connected with two nuts through threads, and the two nuts are positioned on two opposite sides of the connecting block 51, so that the pin shaft 53 and the connecting block 51 are limited relatively. The nut is shown in the drawings. The connecting block 51 is provided with a rotating shaft 52 in a penetrating way, and two ends of the rotating shaft 52 are in rotary connection with the hinged support 6, so that the connecting block 51 is hinged with the hinged support 6. The rotation shaft 52 is perpendicular to the pin shaft 53, so that the support rod 1 and the hinge support 6 can rotate relatively in two directions.

After the length of the support rod 1 and the diagonal brace 3 is changed, the angle can be adjusted adaptively based on the above hinge structure.

When the support rod 1 needs to be disassembled, the pin 53 is disassembled by disassembling the nut, and the connecting block 51 is still connected with the hinged support 6.

Generally, cross bearings, universal joints and the like can be used for the crossed hinging mode, but the structural scheme cannot be well applied to drilling towers. Because the exploration use of the rig is short-term, often requiring replacement locations, or direct removal after the exploration is completed, the connection must be made with ease of removal. In general, the bottom of the supporting rod 1 is directly hinged to the supporting seat 4 after being flattened by a round tube, and if other structural members such as cross bearings are added, the bottom of the supporting rod 1 must be modified, but the scheme can be directly applied according to the structural style of the prior art, and the connecting block 51 can be directly matched and connected with the supporting rod 1 with the flat bottom. In addition, the disassembly of other structural components is inconvenient, and the disassembly can be realized by disassembling two nuts in the scheme, so that the disassembly is very convenient.
