Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of anchor drilling machines, in particular to a prestressed anchor drilling machine. Background Art
[0002] Prestressed anchor drilling rigs are equipment used for drilling and installing anchor rods in projects such as tunnels, slopes, and foundation pits. Commonly used small pneumatic anchor drilling rigs mainly include a base with a power unit slidably connected to the base. The power unit can drive the drill rod into the rock to drill holes. During the deep drilling process, users are required to send the drill rods one by one to the drilling rig for installation, which slows down the construction progress and affects the efficiency of the drill rod delivery of the drilling rig. Moreover, when the drill rod to be installed is moved between the power unit of the drilling rig and the drill rod that has penetrated deep into the rock, most drilling rigs lack a structure to support the drill rod, which requires users to hold the drill rod with their hands and screw one end of the drill rod to the end of the drill rod that has penetrated deep into the rock, affecting the convenience of drill rod installation. Utility Model Content
[0003] The purpose of the utility model is to provide a prestressed anchor drilling rig to solve the problems raised in the above background technology.
[0004] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] base;
[0007] A power device, the power device includes a carrier plate slidably connected to the base, a motor 1 is fixed on the top of the carrier plate, a reducer is installed at the output end of the motor 1, and the output end of the reducer is fixed to one end of the external drill rod;
[0008] The cylinder is fixed inside the base and can drive the carrier to slide along the base;
[0009] The storage box is fixed on the top of the base and can store the drill pipes to be installed;
[0010] The supporting mechanism can drive the drill rod inside the storage box to fall automatically, and can also support the drill rod after falling. The supporting mechanism includes a motor 2 fixedly connected to the storage box, and a connecting shaft is fixed to the output end of the motor 2. The outer side of the connecting shaft is fixed with a support plate 1, a support plate 2 and a support plate 3 in sequence from top to bottom.
[0011] Furthermore, a mounting seat is fixed to the output end of the reducer, and the mounting seat is screwed and fixed to one end of the drill rod.
[0012] Furthermore, a crossbeam is fixed to the output end of the cylinder, and a transmission rod is fixed between the crossbeam and the carrier plate.

DETAILED DESCRIPTION
[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0026] For example 1, please refer to Figure 1 - Figure 4 In the embodiment of the present invention, a prestressed anchor drilling machine includes a base 100, a power device 200 is arranged on the top of the base 100 for sliding, the power device 200 includes a carrier plate 210 slidably connected to the base 100, a motor 220 is fixed on the top of the carrier plate 210, a reducer 230 is installed on the output end of the motor 220, and the output end of the reducer 230 is fixed to one end of the external drill rod, so that the motor 220 can drive the drill rod to rotate, and a cylinder 300 is fixed inside the base 100, and the cylinder 300 can drive the carrier plate 210 to slide along the base 100, so that the power device 200 rotates the drill rod and inserts it into the rock mass. A storage box 400 is fixed on the top of the base 100. A plurality of spare drill rods are stored inside the storage box 400. A supporting mechanism 500 is provided on the outside of the storage box 400. The supporting mechanism 500 can not only drive the drill rods inside the storage box 400 to fall automatically, but also support the drill rods after falling. The supporting mechanism 500 includes a motor 2 510 fixedly connected to the storage box 400. A connecting shaft 520 is fixed to the output end of the motor 2 510. A support plate 1 530, a support plate 2 540 and a support plate 3 550 are fixed to the outside of the connecting shaft 520 in sequence from top to bottom.
[0027] Specifically, a storage box 400 is fixed on the base 100 of the traditional drilling rig, and multiple drill rods to be installed are stored inside the storage box 400. A support mechanism 500 is installed on the outside of the storage box 400. The connecting shaft 520 on the support mechanism 500 rotates 180 degrees with the pallet 1 530 and the pallet 2 540 at the same time, which can enable the storage box 400 to automatically release a drill rod to the base 100 of the drilling rig, eliminating the need for manual frequent delivery of drill rods. The connecting shaft 520 rotates synchronously with the pallet 3 550 to the installation position of the drilling rig, so that the fallen drill rod can be temporarily placed on the pallet 3 550, eliminating the need for manual support of the drill rod for a long time when installing the drill rod, which helps to improve the convenience of drill rod installation.
[0028] like Figure 1 As shown, in this embodiment, a mounting seat 231 is fixed to the output end of the reducer 230, and the mounting seat 231 is screwed and installed with one end of the drill rod. Specifically, when installing the drill rod, one end of the drill rod is first screwed and installed to the end of the drill rod that has been drilled into the rock mass, and then the carrier plate 210 is moved with the entire power device 200 toward the drill rod, so that the mounting seat 231 is plugged into one end of the drill rod, and at the same time, the motor 220 is driven to rotate with the mounting seat 231, so that the mounting seat 231 is screwed and installed with the drill rod.
[0029] In this embodiment, two guide rails are fixed on the top of the base 100, and two sliding grooves are provided on the bottom surface of the carrier 210 for sliding engagement with the corresponding guide rails, so that the carrier 210 can move back and forth stably and smoothly along the base 100.
[0030] like Figure 1 and Figure 3 As shown, in this embodiment, a crossbeam 310 is fixed to the output end of the cylinder 300, and a transmission rod 311 is fixed between the crossbeam 310 and the carrier plate 210. When it is necessary to make the carrier plate 210 carry the power device 200 to push the drill rod toward the rock mass, the output end of the cylinder 300 contracts in length, so that the crossbeam 310 carries the two transmission rods 311 to push the carrier plate 210 toward the rock mass, thereby making the carrier plate 210 carry the entire power device 200 to push the drill rod, so that the drill rod rotates and is inserted into the rock mass.
[0031] In this embodiment, a notch is formed at one end of the base 100, which facilitates the crossbeam 310 to move to the top of the base 100 when moving toward the rock mass. When installing a drill rod, the user uses an external wrench to loosen and disassemble the mounting base 231 and the drill rod, and then extends the output end of the cylinder 300. The carrier plate 210 takes the entire power device 200 away from the drill rod, leaving space between the mounting base 231 and the drill rod that has been drilled into the rock mass for installing a new drill rod.
[0032] like Figure 2As shown, in this embodiment, a support base 110 is fixed to one end of the base 100, and the support base 110 enables the combined drill pipes to drill into the rock mass stably along a straight line.
[0033] As Figure 1 shown, in this embodiment, a baffle 120 is fixed to the top of the base 100, and the baffle 120 can protect the cylinder 300 without interfering with the movement of the carrier plate 210.
[0034] As Figure 1 and Figure 2 shown, in this embodiment, the storage box 400 includes a U-shaped plate 410. Two side plates 420 are fixed to the open side of the U-shaped plate 410. Support rods 412 fixedly connected to the base 100 are fixed to both ends of the U-shaped plate 410 and the outer sides of the side plates 420, so that the storage box 400 is installed and fixed on the base 100. A gap is provided between the two side plates 420, and the gap position facilitates the user to replenish the drill pipes into the storage box 400. Among them, the support rod 412 is of a special-shaped structure to prevent the support rod 412 from hindering the movement of the carrier plate 210 along the base 100.
[0035] As Figure 2 shown, in this embodiment, a connecting seat 411 rotatably connected to the connecting shaft 520 is fixed to the outer side of the U-shaped plate 410, so that the connecting shaft 520 can rotate stably on the outer side of the U-shaped plate 410.
[0036] As Figure 1 - Figure 3 shown, in this embodiment, the top surface of the support plate two 540 is in transmission contact with the bottom open of the storage box 400. In the initial state, the support plate two 540 rotates to support the bottom open of the storage box 400 to prevent the drill pipes inside the storage box 400 from falling automatically. When it is necessary to install the drill pipes on the drilling rig, refer to Figure 1 and Figure 2 , the support plate one 530 rotates into the storage box 400 to intercept the drill pipe above the drill pipe at the falling position, the support plate two 540 rotates away from the storage box 400 to allow one drill pipe to fall, and the support plate three 550 rotates above the base 100 to support the falling drill pipe. Refer to Figure 3 , the connecting shaft 520 rotates the first support plate 530, the second support plate 540, and the third support plate 550 by 180 degrees, causing the third support plate 550 to move away from the base 100, reserving space for the movement of the carrier plate 210. At this time, the second support plate 540 continues to block the bottom of the storage box 400, and the carrier plate 210 moves the power device 200 along the carrier plate 210 to perform the drilling operation with the drill pipe.
[0038] In this embodiment, the first support plate 530, the second support plate 540, and the third support plate 550 are all semi-circular, so that the support plates at different positions can alternately intercept or support the drill pipe. Among them, the third support plate 550 has a larger size, so that the third support plate 550 can support the drill pipe to be installed over a large area.
[0039] As Figure 2 and Figure 4 shown, in this embodiment, an L-shaped plate 560 fixedly connected to the U-shaped plate 410 is fixed to the bottom of the second motor 510, so that the second motor 510 is installed and fixed on the storage box 400.
