Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to an anti-loosening punching device. Background Art

[0002] Construction engineering involves the design, construction and maintenance of buildings. Building materials can include concrete, steel, bricks, wood, etc., and construction methods can involve a variety of technologies such as traditional masonry, steel structure, prefabricated components, etc. Construction engineering includes not only the design and construction of new buildings, but also the maintenance and restoration of existing buildings, which involves regular inspections, repair of damaged parts, and updating of facilities and equipment.

[0003] In construction projects, a punching device is a common tool used to make holes or openings on a series of building materials such as concrete, bricks, metals, etc., so as to install pipes, wires, fixtures, etc. The traditional drilling method is to use a handheld drill to drill holes on the wall. This type of drill is economical and suitable for drilling holes on the wall. Sometimes it is necessary to drill holes on the ground. At present, a water-grinding drill is often used to drill holes on the ground. The existing water-grinding drill is found to have the following problems in the existing technology during use:

[0004] 1. The water-grinding drill itself is large in size, and it generates certain vibrations during operation. During use, in order to prevent the displacement of the drill, the staff needs to step on the bottom plate of the drill, which consumes manpower. Once the staff does not step firmly, the bottom plate is loose and the drill still moves;

[0005] 2. In order to prevent the drilling rig from shifting, some water-grinding drilling rigs will position the bottom plate, penetrate the entire bottom plate with bolts, and fix the bottom plate and the ground together with bolts. The fixing strength of the bolts is not enough, and the threads need to be unscrewed one by one during disassembly, so the disassembly process is more cumbersome. Utility Model Content

[0006] The purpose of the utility model is to provide a punching device that prevents loosening, so as to solve the problem that the traditional water-grinding drill proposed in the above background technology is not fixed by the foot of the staff or by bolts, and is easy to loosen. To achieve the above purpose, the utility model provides the following technical solutions: the punching device that prevents loosening includes a bottom plate, a lifting mechanism and a positioning mechanism are respectively installed on the top of the bottom plate, and a drilling machine body is installed on one side of the lifting mechanism.

[0007] The positioning mechanism includes a fixing plate, a first screw rod is welded to the lower surface of the fixing plate, an auger rod is threadedly connected to the outer surface of the first screw rod, a pinion is welded to the top of the auger rod, a long gear is meshed with one side of the pinion, a rotating shaft is inserted into the inner wall of the long gear, and an output shaft of a first motor is installed at one end of the rotating shaft.

[0008] Further preferably, the lifting mechanism comprises a fixing frame, a second screw rod is inserted into the inner wall of the fixing frame, and an output shaft of a second motor is mounted on the top of the second screw rod.

[0009] Further preferably, the rotating shaft is rotatably connected to the upper surface of the base plate.

[0010] Further preferably, the first screw rod, the auger rod and the pinion gear are arranged as a group, with a total of four groups, and a spiral blade is arranged on the surface of the auger rod.

[0011] Further preferably, a meshing transmission structure is provided between the long gear and the small gear.

[0012] Further preferably, the fixing frame and the upper surface of the bottom plate are welded, and the fixing plate and the fixing frame are connected by rivets.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] In the utility model, a positioning mechanism is installed on the upper surface of the bottom plate. When each auger rod is rotated and displaced downward along the first screw rod, the auger rod is inserted into the soil on the ground through the rotation and forward movement of the spiral blade on the surface of the auger rod, which plays a limiting role on the entire device and prevents the device from loosening and displacing during the drilling process of the drilling machine body.

[0015] In the utility model, by starting the first motor, the rotating shaft and the long gear are driven to rotate, and the rotating shaft rotates along the upper surface of the bottom plate, so that the long gear can always be kept in the same vertical line. The overall length of the long gear is relatively long. When the small gear slides downward along the screw rod, the meshing transmission between the long gear and each small gear drives the four small gears to rotate synchronously. The four spiral drill rods can be inserted into the soil at the same time, and can also be pulled out at the same time, and the operation is faster. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In this embodiment, Figure 1 and Figure 3As shown, the rotating shaft 306 and the upper surface of the base plate 1 are connected in a rotational manner; it should be noted that when the first motor 307 is started, it drives the rotating shaft 306 and the long gear 305 to rotate, and the rotating shaft 306 rotates along the upper surface of the base plate 1, which can keep the long gear 305 always in the same vertical line. The overall length of the long gear 305 is relatively long. When the small gear 304 slides downward along the screw rod, it is always engaged with the edge of the long gear 305.

[0026] In this embodiment, Figure 3 and Figure 4 As shown, the first screw rod 302, the auger rod 303 and the pinion gear 304 are set as a group, with a total of four groups, and the surface of the auger rod 303 is provided with a spiral blade; it should be noted that the four groups of components are respectively located at the four corners of the long gear 305, and the four first screw rods 302 are welded to the lower surface of the fixed plate 301. The four groups of components are limited by the first screw rod 302 and can slide up and down along the first screw rod 302. When each auger rod 303 rotates and moves downward along the first screw rod 302, the auger rod 303 is inserted into the soil on the ground through the rotation and forward movement of the spiral blade on the surface of the auger rod 303, which has the effect of limiting and fixing.

[0027] In this embodiment, Figure 2 and Figure 3 As shown, a meshing transmission structure is set between the long gear 305 and the small gear 304; it should be noted that when the long gear 305 rotates, the meshing transmission between the long gear 305 and each small gear 304 drives the four small gears 304 to rotate synchronously, so that the four spiral drill rods 303 can be inserted into the soil at the same time, and can also be pulled out at the same time, which makes the operation faster.

When the long gear 305 rotates, it drives the four small gears 304 to rotate synchronously. When the four small gears 304 rotate synchronously, they drive the four spiral drill rods 303 to move downward along the four first screw rods 302. The spiral blade on the surface of the spiral drill rod 303 rotates and moves forward, and the spiral drill rod 303 is inserted into the ground. The second motor 203 is started to rotate the second screw rod 202 through the output shaft of the second motor 203, and further drives the drilling machine body 4 to slide up and down along the second screw rod 202. The drilling machine body 4 belongs to the prior art and adopts a three-phase HDZ-L water-grinding drilling rig. The diamond drill bit below the drilling machine body 4 can drill holes along the ground.
