Description

Technical Field

[0001] The utility model relates to the technical field of drilling rigs, in particular to a composite drilling rig based on the transformation of a three-axis mixing drilling rig. Background Art

[0002] The three-axis mixing drill is a large-scale equipment that mixes three axes synchronously, sprays cement slurry into the mixed and cut soil, and forms a cement soil continuous wall through tangent piles. Its characteristics are slow in and out. Due to the heavy weight of the three axes, a complex gear system is required to balance the power, resulting in an extremely slow lifting speed of the three axes. Figure 1 As shown, it is a top view of the three-axis mixing drill, and it can be clearly seen that a large number of pulleys are provided to form a complex gear train 7, so the running speed is extremely slow.

[0003] At present, as the competition for mixing drills in the construction market has become increasingly fierce, three-axis mixing drills, as the main force in the original market, are now unprofitable, and due to their single function, a large part of the three-axis drilling rigs are idle.

[0004] Therefore, how to transform the three-axis mixing drill to increase its response speed while meeting multi-functional requirements to avoid the idleness and waste of resources of the three-axis mixing drill has become a technical problem that needs to be solved urgently.

[0005] In order to solve the above problems, people have been seeking an ideal technical solution. Utility Model Content

[0006] The utility model aims to address the deficiencies of the prior art and thus provide a composite drilling rig based on the transformation of a three-axis mixing drilling rig, which has a faster lifting speed and a composite capability.

[0007] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a composite drilling rig based on the transformation of a three-axis mixing drilling rig, including a bracket, a driving chain, a driving motor, a drilling tool quick-installation device and a drill rod pushing device;

[0008] The drilling tool quick-install device is arranged on the bracket in a manner that it can be raised and lowered by a driving chain, and the driving chain is driven by the driving motor to perform a rotary motion;

[0009] The drill rod pushing device is arranged at a high position of the bracket, and is used to push the drill rod horizontally, so that the drill rod switches positions between the position close to the bracket and the position connected to the drilling tool quick-installation device;

[0010] The drilling tool quick-install device and the drill rod are quickly connected by a socket-and-spigot method;

[0011] The drill rod pushing device and the drill rod are locked and fixed via a clamping mechanism.

[0012] Based on the above, a top frame and a sprocket that cooperate with the driving chain are arranged at the top end of the bracket, the width of the top frame is greater than the width of the bracket, and the sprocket is installed at least at both ends of the top frame in the length direction.

[0013] Based on the above, the drill tool quick-release device includes a drill rod motor, a main body and a quick-release male joint. The drill rod motor and the quick-release male joint are respectively installed at the upper and lower ends of the main body. The drill rod motor is used to drive the quick-release male joint to rotate; a quick-release female joint is arranged at the top of the drill rod, and the quick-release male joint and the quick-release female joint are quickly connected by a socket manner.

[0014] Based on the above, the drill rod pushing device includes a horizontal slide rail, a horizontal telescopic rod and the clamping mechanism installed on the bracket, the horizontal slide rail is fixed on the bracket and extends horizontally to form a track, the clamping mechanism slides with the horizontal slide rail, the base of the horizontal telescopic rod is hinged to the bracket, and the action end of the horizontal telescopic rod is hinged to the tail end of the clamping mechanism.

[0015] Based on the above, the clamping mechanism is an electric-controlled clamping mechanism, a hydraulic clamping mechanism or a pneumatic clamping mechanism, and the action end of the clamping mechanism includes two arc plates that can be closed to form an arc jaw structure and an electric push rod or a hydraulic cylinder or a pneumatic cylinder that drives the two arc plates to engage or release.

[0016] Based on the above, a centering sensor is arranged between the drill tool quick-installation device and the drill rod pushing device, and the centering sensor is a laser beam sensor or a beam photoelectric switch or an image recognition unit.

[0017] Based on the above, the driving motor is installed on the base of the bracket.

[0018] The utility model has substantial characteristics and progress compared with the prior art. Specifically, the utility model has the following advantages:

[0019] 1. This application transforms the original three-axis mixing drill rig, removes all gear train components, and adopts a drive chain and motor belt gear train system. The combination of chain and sprocket has the advantages of fast speed and high precision, and can transform the traditional three-axis mixing drill rig into a composite pile driver or root pile driver, etc.

[0020] 2. Since most of these pile drivers require a connected drill rod, the present application provides a drill tool quick-install device and a drill rod pushing device. The quick-install cooperation between the drill tool quick-install device and the drill rod is used to realize the rapid separation and connection of the drill rod and the drill tool quick-install device. The drill rod pushing device is used to always keep the connected drill rod at a higher position on the bracket. After the first drill rod is driven into the ground, the second drill rod can be quickly connected, thereby improving efficiency and making up for the defect that the original three-axis mixing drilling rig does not have these functions.

DETAILED DESCRIPTION

[0027] The technical solution of the utility model is further described in detail below through specific implementation methods.

[0028] like Figure 2-Figure 5 As shown, a composite drilling rig based on the modification of a three-axis mixing drilling rig includes a bracket 1, a driving chain 2, a driving motor 3, a drilling tool quick-install device 4 and a drill rod pushing device 5, and the driving motor 3 is installed on the base of the bracket 1.

[0029] The drill tool quick-loading device 4 is arranged on the bracket 1 so as to be liftable through the driving chain 2. The driving chain 2 is driven by the driving motor 3 to make a rotational motion. The drill tool quick-loading device 4 is installed on the driving chain 2. Through the operation of the driving motor 3, the drill tool quick-loading device 4 can be quickly lifted and lowered to meet the drilling needs.

[0030] The drill rod pushing device 5 is arranged at a high position of the support 1, and is used to push the drill rod 6 horizontally, so that the drill rod 6 switches positions between the position close to the support 1 and the position connected to the drilling tool quick-installation device 4;

[0031] The drilling tool quick-install device 4 and the drill rod 6 are quickly connected by a socket-and-spigot method;

[0032] The drill rod pushing device 5 and the drill rod 6 are locked and fixed by a clamping mechanism.

[0033] In this embodiment, there are two drill rods 6. The first drill rod is directly connected to the drill tool quick-install device 4 in advance, and a quick socket structure is used for connection. The drill tool quick-install device 4 includes a drill rod motor 41, a main body 42 and a quick-install male connector 43. The drill rod motor 41 and the quick-install male connector 43 are respectively installed at the upper and lower ends of the main body 42. The drill rod motor 41 is used to drive the quick-install male connector 43 to rotate. The upper and lower ends of the main body 42 are fixed to the drive chain 2.

[0034] A quick-release female connector 61 is disposed at the top end of the drill rod 6 , and the quick-release male connector 43 and the quick-release female connector 61 are quickly connected in a socket-and-spigot manner.

[0035] This quick-release connection method is widely used in the drilling tool industry, especially in the scenario where multiple rods need to be connected to drill rods. The quick-release method is often used to achieve quick disassembly and connection. The principle of axial interlocking after socketing is similar to the quick socket joint of the water pipe. In essence, a through pin 44 is arranged inside, half of which is located in the male joint and the other half is located in the female joint, thereby realizing axial interlocking; in the radial direction, the quick-release male joint and the quick-release female joint are socketed in the form of non-rotating fit such as hexagonal sockets, thereby realizing radial interlocking.

[0036] When drilling, the power source for the rotational drive of the drill rod 6 comes from the drill rod motor 41 installed on the drilling tool quick-install device 4.

[0037] The top of the bracket 1 is provided with a top frame 11 and a sprocket 12 for cooperating with the drive chain 2. The width of the top frame 11 is greater than the width of the bracket 1. The sprocket 12 is installed at least at both ends of the top frame 11 in the length direction, so that the drive chain 2 is suspended relative to the bracket 1 to prevent interference with the bracket 1 in space.

[0038] The drill rod pushing device 5 includes a horizontal slide rail 51, a horizontal telescopic rod 52 and the clamping mechanism 53 installed on the bracket. The horizontal slide rail 51 is fixed on the bracket 1 and extends horizontally to form a track. The clamping mechanism 53 slides with the horizontal slide rail 51. The base of the horizontal telescopic rod 52 is hinged to the bracket 1, and the action end of the horizontal telescopic rod 52 is hinged to the tail end of the clamping mechanism 53.

[0039] In this embodiment, the horizontal telescopic rod 52 can be a hydraulic rod, which has a strong driving force and can be precisely controlled; the clamping mechanism 53 is an electrically controlled clamping mechanism, a hydraulic clamping mechanism, or a pneumatic clamping mechanism, and the action end of the clamping mechanism includes two arc plates that can be closed to form an arc jaw structure and an electric push rod, a hydraulic cylinder, or a pneumatic cylinder that drives the two arc plates to engage or release.

[0040] In order to smoothly realize the centering installation of the connected drill rod, a centering sensor (not shown in the figure) is arranged between the drill tool quick-installation device 4 and the drill rod pushing device 5. The centering sensor is a laser beam sensor or a beam photoelectric switch or an image recognition unit. It can be installed at a specific position between the drill tool quick-installation device 4 and the drill rod pushing device 5 according to the requirements of the corresponding sensor, generally facing each other in the vertical direction.

[0041] Working principle description:

[0042] The first drill rod 6 is directly installed on the drilling tool quick installation device 4 by quick connection, and the second drill rod 6 is clamped by the drill rod pushing device 5 and temporarily placed near the bracket.

[0043] When drilling is required, the drill rod motor drives the drill rod to rotate, and at the same time, the drive motor 3 is controlled to drive the drill rod to move downward through the drive chain 2 to achieve drilling.

[0044] When the first drill rod 6 is drilled into place, it is paused, the quick-connect joint is opened manually, the drilling tool quick-install device 4 is released, and then the driving motor 3 quickly returns to the high setting position through the driving chain 2.

[0045] After it is in place, the drill rod pushing device 5 is controlled to push the second drill rod to the target position. The target position can be determined by controlling the stroke of the horizontal telescopic rod 52, or by using the assistance of a centering sensor to achieve precise position centering.

[0046] After moving into position, the top of the drill rod is aligned with the drill tool quick-install device 4, and the drill tool quick-install device 4 is controlled to descend, so that the quick-install female joint at the top of the drill rod 6 and the quick-install male joint in the drill tool quick-install device 4 are docked and interlocked.

[0047] Generally, the stop state of the drilling tool quick-install device 4 after shutdown can control the internal hexagonal of the quick-install male connector to stop at a set angle to match the docking angle of the second drill rod.

[0048] When the hexagonal sockets of the two cannot be directly connected, the drill rod motor 41 in the remote-controlled drilling tool quick-install device 4 can be rotated slowly at a small angle to match the two.

[0049] Alternatively, a cone angle introduction method can be used while controlling the motor to idle to achieve introduction interlock.

[0050] Alternatively, when the centering sensor is an image recognition unit, the rotation angle of the quick-release male connector can be adjusted through image recognition to solve the problem.

[0051] The bottom end of the second drill bit needs to be connected to the top end of the previous drill bit on the ground. This work can be done manually, either by quick installation or by flange connection.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for protection of the utility model.
