Description

Technical Field

[0001] The utility model relates to the technical field of drilling equipment, in particular to a deep foundation pit excavation drilling equipment. Background Art

[0002] A deep foundation pit refers to a project with an excavation depth of more than 5 meters, or a project with a depth of less than 5 meters but particularly complex geological conditions, surrounding environment and underground pipelines. Drilling equipment is sometimes required during the excavation process of a deep foundation pit. Drilling equipment such as a water-milling drill has a water-milling drill body consisting of a rotating drum and a drill bit. The drill bit of a water-milling drill body is prone to damage after a long time, and thus needs to be replaced. In order not to delay work, the staff carry a spare water-milling drill body when the water-milling drill enters the foundation pit. When the water-milling drill body is damaged, it can be replaced directly in the foundation pit. However, the overall length of the water-milling drill body is relatively long and it is not convenient for the staff to carry. Utility Model Content

[0030] The embodiment of the present application provides a deep foundation pit excavation drilling equipment, which effectively solves the technical problem that in order not to delay the work, the workers carry a spare water drill body when the water drill enters the foundation pit, and when the water drill body is damaged, it can be directly replaced in the foundation pit, while the overall length of the water drill body is long and it is inconvenient for the workers to carry.

[0031] Example

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 4 The technical solution in the embodiment of the present application effectively solves the technical problem that the staff carry a spare water-mill drill body when the water-mill drill enters the foundation pit in order not to delay the work, and directly replaces the water-mill drill body in the foundation pit when the water-mill drill body is damaged, while the overall length of the water-mill drill body is long and inconvenient for the staff to carry. The overall idea is as follows:

[0033] In view of the problems existing in the prior art, the utility model provides a deep foundation pit excavation drilling device, which includes a drilling machine 1, the outside of the drilling machine 1 is rotatably connected with a rotating drum 2, a drill bit 3 is arranged at the lower end of the rotating drum 2, two positioning blocks 4 are fixedly installed on a side of the drill bit 3 close to the rotating drum 2, positioning holes 5 are opened on the outside of the two positioning blocks 4, and two connecting mechanisms are arranged on a side of the rotating drum 2 close to the drill bit 3;

[0034] Each connecting mechanism includes a positioning groove 6, a rotation groove 7 and a threaded rod 8;

[0035] The positioning groove 6 is formed on one side of the rotary drum 2 close to the drill bit 3, the rotating groove 7 is formed on one side of the rotary drum 2 close to the positioning groove 6, and the threaded rod 8 is rotatably connected inside the rotating groove 7;

[0036] The two positioning blocks 4 are respectively clamped in the inside of the two positioning grooves 6, and the two threaded rods 8 are respectively rotatably connected in the inside of the positioning holes 5, and the two positioning holes 5 are both threaded holes.

[0037] By setting the positioning hole 5 outside the positioning block 4 and cooperating with the threaded rod 8, when the drill bit 3 is damaged, the threaded rod 8 is rotated to release the connection between the threaded rod 8 and the positioning hole 5. At this time, the drill bit 3 is pulled to release the connection between the positioning block 4 and the positioning groove 6. At this time, the drill bit 3 is disassembled. When installing the drill bit 3, the positioning block 4 is clamped in the inside of the positioning groove 6. At this time, the threaded rod 8 is rotated to enter the inside of the positioning hole 5 through the rotating groove 7 to fix the positioning block 4 in the inside of the positioning groove 6. At this time, the drill bit 3 is installed, which is convenient for directly replacing the damaged drill bit 3 without replacing the entire drill bit. The drill bit 3 is small in size and convenient for the staff to carry.

[0038] A square groove 9 is formed on one side of the rotating drum 2 close to each threaded rod 8;

[0039] The square groove 9 is connected to the rotating groove 7, and the end of the threaded rod 8 away from the positioning hole 5 is located inside the square groove 9, so as to prevent the threaded rod 8 from protruding out of the rotating drum 2 and contacting the punching surface when the drilling equipment is working, causing damage.

[0040] Each square groove 9 has a built-in groove 10 formed inside;

[0041] Wherein, a baffle 11 is slidably connected inside each built-in groove 10 to provide protection for the threaded rod 8 .

[0042] A limiting groove 12 is formed inside each built-in groove 10, and a limiting plate 13 is fixedly mounted outside each baffle 11;

[0043] The limiting plate 13 is slidably connected to the inside of the limiting groove 12 , and the distance that the baffle plate 11 slides down makes the baffle plate 11 incompletely close the square groove 9 , which is convenient for the staff to move the baffle plate 11 .

[0044] A spring 14 is fixedly connected to the interior of each built-in groove 10;

[0045] The spring 14 is fixedly connected to the outside of the limiting plate 13 to provide support for the baffle 11 .

[0046] A through hole 15 is formed on the outside of the drill bit 3;

[0047] The drill bit 3 is composed of a cylinder and a drill bit body, and the through hole 15 is located outside the cylinder. When the positioning block 4 is stuck in the positioning groove 6 and is not convenient to pull, a tool is used to insert into the through hole 15 to facilitate pulling the drill bit 3.

[0048] By setting a baffle 11 inside the built-in groove 10 and cooperating with the spring 14, before rotating the threaded rod 8, use a tool to make the baffle 11 enter the interior of the built-in groove 10, at this time the spring 14 is compressed and the threaded rod 8 is exposed, at this time the tool is used to rotate the threaded rod 8 to make the threaded rod 8 enter the interior of the positioning hole 5 or the connection between the threaded rod 8 and the positioning hole 5 is released, when the threaded rod 8 enters the interior of the positioning hole 5, release the baffle 11, under the action of the spring 14 the baffle 11 moves downward to cover the threaded rod 8, to prevent the collision of impurities with the threaded rod 8 and damage to the threaded rod 8 when the drilling machine 1 is working.

[0049] Working principle:

[0050] In the first step, when the drill bit 3 is damaged, a tool is used to make the baffle 11 enter the interior of the built-in groove 10, at which time the spring 14 is compressed and the threaded rod 8 is exposed, and the threaded rod 8 is rotated to release the connection between the threaded rod 8 and the positioning hole 5, and at this time, the drill bit 3 is pulled to release the connection between the positioning block 4 and the positioning groove 6, and the drill bit 3 is disassembled;

[0051] The second step is to clamp the positioning block 4 into the positioning groove 6 when installing the drill bit 3, and use a tool to make the baffle 11 enter the built-in groove 10. At this time, the spring 14 is compressed and the rotating groove 7 is exposed. At this time, the rotating threaded rod 8 enters the interior of the positioning hole 5 through the rotating groove 7 to fix the positioning block 4 in the interior of the positioning groove 6. At this time, the drill bit 3 is installed, and the baffle 11 is loosened. Under the action of the spring 14, the baffle 11 moves downward to cover the threaded rod 8.

[0052] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
