DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part 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 creative work are within the scope of protection of the present invention.

[0021] like Figures 1 to 4 As shown, a typical embodiment of the present invention provides a liftable drilling device, comprising: a drilling machine 1, a handle 2, a base 3, a support 4, a reversing assembly 5 and a lifting assembly 6;

[0022] A cavity is provided at the bottom end of the pillar 4, and the drilling rig 1 is arranged at the top end of the pillar 4. The drilling rig 1 includes a drill bit 1.1 and a mobile box 1.2. The drill bit 1.1 is detachably mounted on the top end of the mobile box 1.2. Grooves 1.3 are provided at both ends of the mobile box 1.2, and sliding rods 1.4 are fixedly installed in the two grooves 1.3. A handle 2 is provided at the top end of the pillar 4, and the handle 2 is set in an L shape. The side of the handle 2 away from the base 3 contacts the bottom end of the mobile box 1.2. The pillar 4 is slidably arranged on the top surface of the base 3 in the height direction. The reversing component 5 includes a rotating shaft 5.1, and the rotating shaft 5.1 is provided with two. The two rotating shafts 5.1 are respectively rotatably mounted on the inner walls on both sides of the top end of the pillar 4, and a strip plate 5.2 is fixedly mounted on the rotating shaft 5.1. A strip groove 5.3 is provided on the strip plate 5.2. Two sliding rods 1.4 are respectively slidably installed in the strip groove 5.3, and the lifting component 6 is arranged in the cavity.

[0023] When it is necessary to drill a hole in the subway wall, the base 3 is moved to a designated location, and the height of the pillar 4 is controlled by starting the lifting component 6, so that the drilling rig 1 can be moved to the designated height, and the reversing component 5 is driven by the control handle 2 to rotate at the top of the pillar 4 through the rotating shaft 1 5.1, and the strip plate 5.2 is driven to rotate. When the strip plate 5.2 rotates, the sliding rod 1.4 can be driven to rotate, and when the sliding rod 1.4 rotates, the moving box 1.2 can be driven to rotate, and the drill bit 1.1 is replaced. When the drill bit 1.1 is replaced, the handle 2 is pressed down, so that the side of the handle 2 away from the base 3 pushes the bottom end of the moving box 1.2, and the sliding rod 1.4 slides inside the strip groove 1 5.3. At this time, the drilling rig 1 can be pushed into the wall to complete the drilling operation on the wall.

[0024] The reversing assembly 5 also includes a toggle rod 5.4, a connecting plate 5.5 and a spring 5.6. Two connecting plates 5.5 are provided and are respectively located on both sides of the handle 2. The two connecting plates 5.5 are respectively fixedly mounted on the outer walls at both ends of the toggle rod 5.4, and one end of the connecting plate 5.5 away from the toggle rod 5.4 is fixedly mounted on the rotating shaft 1 5.1.

[0025] When the toggle rod 5.4 rotates, it can drive the connecting plate 5.5 to rotate. When the connecting plate 5.5 rotates, it can drive the rotating shaft 1 5.1 to rotate, drive the strip plate 5.2 to rotate, and drive the drilling rig 1 to shift.

[0026] The spring 5.6 is parallel to the strip plate 5.2, and the spring 5.6 is fixedly mounted on the outer wall of the rotating shaft 1 5.1, and one end of the spring 5.6 away from the rotating shaft 1 5.1 is fixedly mounted on the outer wall of the sliding rod 1.4.

[0027] When the drilling rig 1 is displaced and moves in translation, the distance between the bottom end of the mobile box 1.2 and the rotating shaft 5.1 becomes larger, so that the spring 5.6 is stretched. When the spring 5.6 is stretched, it provides an elastic force in the direction of the rotating shaft 5.1, and enables the bottom end of the mobile box 1.2 to pass over the corner of the handle 2 and stabilize in a vertical state parallel to the ground. When the handle 2 is pressed down, the handle 2 pushes the mobile box 1.2 to move. When the handle 2 is reset, the spring 5.6 is reset at the same time, which can restore the mobile box 1.2 to its initial state, making it easy to pull it out of the hole.

[0028] A slot 2.1 is provided on one side of the handle 2 facing the base 3, and the toggle rod 5.4 can be inserted into the slot 2.1. The slot 2.1 is set in an arc shape. A strip groove 2.2 is provided on the side of the handle 2 away from the drilling rig 1. A rotating shaft 2.3 is slidably installed inside the strip groove 2.2. The rotating shaft 2.3 is fixedly installed on the outer wall of the support 4 on the side away from the drilling rig 1.

[0029] When the toggle rod 5.4 is inserted into the slot 2.1, the handle 2 is displaced laterally, which can cause the toggle rod 5.4 to be displaced. When the toggle rod 5.4 is displaced, it can rotate around the rotation axis 1 5.1 as the center of the circle, and drive the strip plate 5.2 to rotate. When the handle 2 is pressed down, the arc-shaped slot 2.1 can facilitate the toggle rod 5.4 to be separated from the handle 2, so that the moving box 1.2 can be kept vertical or parallel to the ground when the handle 2 is pressed down. The strip groove 2.2 can limit the moving distance of the handle 2. When the rotation axis 2.3 is at both ends of the strip groove, it can correspond to the vertical and parallel state of the drilling rig 1.

[0030] The lifting assembly 6 comprises an electric push rod 6.1, the top end of which is fixedly mounted on the top inner wall of the cavity, and the bottom end of which is fixedly mounted on the top surface of the base 3.

[0031] When the height of the support 4 needs to be adjusted, the movement of the support 4 in the height direction is controlled by controlling the extended length of the electric push rod 6.1.

[0032] The outer wall of the electric push rod 6.1 is sleeved with a stabilizing sleeve 6.2, the bottom end of which is fixedly mounted on the top surface of the base 3, the outer wall of the stabilizing sleeve 6.2 fits the inner wall of the cavity, and the support 4 is slidably sleeved on the stabilizing sleeve 6.2.

[0033] When the support column 4 is displaced in height, the support column 4 can slide outside the stabilizing sleeve 6.2, so as to keep the support column 4 stable when it is displaced in height direction.

[0034] An extension rod 2.4 is fixedly mounted on the end of the handle 2, and the extension rod 2.4 extends downward. An insertion rod 2.5 is slidably mounted at the center of the second strip groove 2.2, and the side surface of the insertion rod 2.5 contacts the outer wall of the second rotating shaft 2.3.

[0035] The extension rod 2.4 can increase the length of the handle 2. When the height of the pillar 4 changes, the operator can still operate the handle 2 on the ground to press down and move it. When the rotating shaft 2.3 is at the end of the strip groove 2.2, the insertion rod 2.5 is inserted into the strip groove 2.2, which can prevent the rotating shaft 2.3 from sliding inside the strip groove 2.2, and can keep the drilling rig 1 vertical or parallel to the ground. At the same time, the handle 2 can rotate stably with the rotating shaft 2.3 as the center.

[0036] Sliding grooves 4.1 are provided on both sides of the pillar 4. The sliding grooves 4.1 are set to be arc-shaped. Both ends of the sliding grooves 4.1 are connected to strip grooves 4.2. The two strip grooves 4.2 are perpendicular to each other. The sliding rod 1.4 is slidably installed in the sliding grooves 4.1.

[0037] When the sliding rod 1.4 is located at both ends of the sliding groove 4.1, the drilling machine 1 is in a state of being vertical or parallel to the ground, and when the sliding rod 1.4 slides in the strip groove 4.2, the drilling machine 1 can drill into the wall or be pulled out from the wall.

[0038] The technical scope of the present invention is not limited to the contents of the above description. Those skilled in the art can make various deformations and modifications to the above implementation without departing from the technical idea of ​​the present invention, and these deformations and modifications should all fall within the scope of the present invention.
