Description

Technical Field

[0001] This invention relates to the field of engineering machinery technology, and more specifically, to a construction device with a column. Background Technology

[0002] In construction machinery, columns have a wide range of applications. For example, in various drilling rigs (such as rotary drilling rigs, auger drilling rigs, or casing drilling rigs) or pile drivers, columns serve as masts, mainly playing the roles of load-bearing, guiding, and acting as tracks.

[0003] However, during use, due to the load of friction between the power head, drill rod, or soil on the drilling tool, the column may bend to one side, for example, towards the side where the power head or drill rod is located, resulting in reduced construction accuracy and even the risk of column breakage.

[0004] Therefore, how to reduce the risk of column bending is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a construction device with a column that can reduce the risk of column bending.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A construction device with a column, comprising:

[0008] The machine body is equipped with a main winch, and the main winch has a first wire rope;

[0009] A column is provided on the machine body. A working device is installed on the column. A goose head frame is provided on the top of the column. A first pulley group is provided at one end of the goose head frame corresponding to the working device. A first steel wire rope passes around the first pulley group and is connected to the working device.

[0010] A lever mechanism, located on the column or the body, includes an input end and an output end. The input end is linked to the force of the first wire rope, and the output end is connected to a back pull rope. The other end of the back pull rope is connected to the goose head frame. The connection positions of the back pull rope and the goose head frame are located on both sides of the column, respectively, as are the first pulley group.

[0011] Optionally, the input end is provided with a first pulley, and the first wire rope passes around the first pulley.

[0012] Optionally, the goose head frame is provided with a second pulley and a third pulley, and the first wire rope passes through the second pulley, the first pulley group, the third pulley and the first pulley in sequence, and the end of the first wire rope near the first pulley is fixed to the column.

[0013] Optionally, the lever mechanism includes a fixed frame connected to the column and a lever hinged to the fixed frame, wherein the distance from the hinge point of the lever and the fixed frame to the rotation center of the first pulley is L3, and the distance from the hinge point to the output end is L4.

[0014] The working device is equipped with a second pulley group, and the first steel wire rope is wound between the first pulley group and the second pulley group, so that 2N parallel rope segments for load bearing are formed between the working device and the goose head frame. The distance from the rotation center of the first pulley group to the center of the column is L1, and the distance from the connection position to the center of the column is L2.

[0015] ,

[0016] Where N is the number of fixed pulleys in the first pulley group.

[0017] Optionally, the portion of the first wire rope located between the working device and the first pulley block includes a tension sensor, and the machine body or the column is provided with a first adjusting cylinder. The first adjusting cylinder is connected to the input end, and the tension sensor and the first adjusting cylinder are respectively connected to a control device. The control device controls the output force of the first adjusting cylinder according to the detection signal of the tension sensor.

[0018] Optionally, the back pull rope is connected to the output end and / or the goose head frame via a length adjustment mechanism.

[0019] Optionally, the lever mechanism is located at the lower part of the column.

[0020] Optionally, the lever mechanism includes:

[0021] The fixing frame is connected to the column;

[0022] The lever section includes two parallel levers and a connecting section between the two levers. The two levers are respectively hinged to the fixed frame. The connecting section includes at least two spaced-apart first connecting sections and two spaced-apart second connecting sections. The input end is located between the two first connecting sections, and the output end is located between the two second connecting sections.

[0023] Optionally, the fixing frame includes a first fixing member and a second fixing member and a third fixing member respectively connected to the first fixing member and spaced apart. The ends of the second fixing member and the third fixing member away from the first fixing member are connected to an end member. The end member has an opening. The lever portion is located between the second fixing member and the third fixing member, and the output end extends from the opening; and / or,

[0024] One of the top and bottom of the fixing frame is connected to the column via a connecting shaft, and the other is connected to the column via fasteners.

[0025] Optionally, the construction device is a rotary drilling rig or a pile driver.

[0026] The construction device with a column provided by the present invention has at least the following beneficial effects:

[0027] The column or body is equipped with a lever mechanism, which includes an input end and an output end. By linking the input end of the lever mechanism with the force of the first wire rope, and connecting the output end of the lever mechanism to the back tension rope, the other end of the back tension rope is connected to the gooseneck frame. The lever mechanism and the back tension rope work together to balance the bending moment generated during operation, effectively reducing the bending deformation of the column itself. It can be understood that by designing the lever arm length and input-output ratio of the lever mechanism, using the tension of the first wire rope as the input, a opposite tension can be generated at the output end of the lever mechanism—that is, the tension of the back tension rope. This generates a reverse torque in the back tension rope, thereby offsetting part or all of the bending moment generated by the working resistance on the column, significantly reducing the bending amplitude of the column, ensuring construction accuracy and safety. For example, when the working device (such as the power head) is drilling, especially when encountering complex strata, the drill bit will encounter large, uneven resistance. This resistance is transmitted to the column through the drill pipe and power head, generating a bending moment on the column, causing it to tend to bend forward (towards the drilling direction). On the other hand, because the input end of the lever mechanism is linked to the force of the first wire rope, when the tension of the first wire rope increases, the balancing tension of the back tension rope is increased simultaneously through the lever mechanism. The larger the bending moment, the larger the balancing moment automatically becomes, thereby achieving dynamic balance of the column torque. Therefore, the stability of the column can be improved and the bending deformation of the column can be reduced. Moreover, because the input end of the lever mechanism is linked to the force of the first wire rope, the back tension rope can respond promptly to the torque generated by the load on the column to balance the torque, solving the problem of delayed torque balance adjustment. At the same time, the lever mechanism matches the force at the output end with the force of the first wire rope, making the torque magnitude for torque balance adjustment more appropriate.

Detailed Implementation

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] The core of this invention is to provide a construction device with a column, which can reduce the risk of column bending.

[0039] Please refer to Figure 1This invention provides a construction device with a column, including a body 1, a column 3, and a lever mechanism 6. The body 1 is equipped with a main winch 2, which has a first wire rope 21. The column 3 is located on the body 1 and is equipped with a working device 4. The top of the column 3 is equipped with a gooseneck frame 5, and one end of the gooseneck frame 5 corresponding to the working device 4 is equipped with a first pulley group 51. The first wire rope 21 passes around the first pulley group 51 and is connected to the working device 4. The lever mechanism 6 is located on the column 3 or the body 1 and includes an input end and an output end. The input end is linked to the force of the first wire rope 21, and the output end is connected to a back pull rope 7. The other end of the back pull rope 7 is connected to the gooseneck frame 5. The connection positions of the back pull rope 7 and the gooseneck frame 5 and the first pulley group 51 are respectively located on both sides of the column 3.

[0040] It should be noted that the machine body 1 serves as the foundation and support platform for the entire construction device. It can house an engine, hydraulic system, or control room, and may also have a walking mechanism. The main winch 2 is the lifting power source. The main winch 2 provides lifting force and downward pressure to the working device 4 by winding and unwinding the first wire rope 21 through the first pulley block 51. The working device 4 can be a power head, which can be slidably mounted on the guide rail of the column 3. For example, the power head outputs torque and speed to drive the drill rod and drill bit to rotate, breaking rock and soil, etc. The column 3 is vertically or inclinedly mounted on the machine body 1, used to mount the working device 4 and / or provide guide rails for it. A gooseneck frame 5 is mounted on the top of the column 3; that is, the gooseneck frame 5 is an extension and fixing frame 62 at the top of the column 3, which serves to mount and support the first pulley block 51, etc. It is understood that after the first wire rope 21 passes around the first pulley block 51, it hangs down and connects to the working device 4.

[0041] More importantly, the column 3 or the body 1 is equipped with a lever mechanism 6, which includes an input end and an output end. In this embodiment of the invention, the input end of the lever mechanism 6 is linked to the force of the first wire rope 21, and the output end of the lever mechanism 6 is connected to the back pull rope 7. The other end of the back pull rope 7 is connected to the gooseneck frame 5. By utilizing the action of the lever mechanism 6 and the back pull rope 7, the bending moment generated during the operation of the working device 4 is balanced, thereby effectively reducing the bending deformation of the column 3 itself. It can be understood that by designing the lever 631 arm length and input-output ratio of the lever mechanism 6, the tension of the first wire rope 21 is used as the input of the lever mechanism 6. This generates a tension in the opposite direction at the output end of the lever mechanism 6, namely the tension of the back pull rope 7, causing the back pull rope 7 to generate a reverse torque. This offsets part or all of the bending moment generated by the working resistance on the column 3, greatly reducing the bending amplitude of the column 3, thus ensuring construction accuracy and construction safety. For example, when the working device 4 (such as the power head) is drilling, especially when encountering complex strata, the drill bit will encounter large and uneven resistance. This resistance will be transmitted to the column 3 through the drill rod and the power head, generating a bending moment on the column 3, causing the column 3 to tend to bend forward (towards the drilling direction). On the other hand, since the input end of the lever mechanism 6 is linked to the force of the first wire rope 21, when the tension of the first wire rope 21 increases, the balancing tension of the back tension rope 7 is increased simultaneously through the lever mechanism 6. When the bending moment is larger, the balancing moment also increases automatically, thereby achieving dynamic balance of the moment of the column 3. Therefore, the stability of the column 3 can be improved and the bending deformation of the column 3 can be reduced. Moreover, since the input end of the lever mechanism 6 is linked to the force of the first wire rope 21, the lever mechanism 6 can make the back pull rope 7 respond to the torque generated by the load on the column 3 in a timely manner to balance the torque and solve the problem of delay in torque balance adjustment. At the same time, the lever mechanism 6 makes the force at the output end match the force of the first wire rope 21, so that the torque of torque balance adjustment is more appropriate.

[0042] It should be noted that this embodiment does not limit the specific implementation of the force linkage between the input end and the first wire rope 21, as long as the force linkage between the input end and the first wire rope 21 can be achieved, that is, the force of the first wire rope 21 can be fed back to the input end of the lever mechanism 6 in real time.

[0043] Please refer to Figure 2 In some embodiments, the input end of the lever mechanism 6 is provided with a first pulley 61, and the first wire rope 21 passes around the first pulley 61.

[0044] In other words, this embodiment sets a first pulley 61 at the input end of the lever mechanism 6, allowing the first wire rope 21 to pass around the first pulley 61. Thus, the force of the first wire rope 21 is transmitted to the input end of the lever mechanism 6 through the first pulley 61. In this scheme, the power of the lever mechanism 6 directly comes from the first wire rope 21; that is, the power of the lever mechanism 6 is the tension generated by the load acting on the first wire rope 21. There is no need to add an additional power mechanism to control the force at the input end of the lever mechanism 6. An increase in load will lead to an increase in the tension of the first wire rope 21, thereby affecting the tension of the back tension rope 7 acting on the goose head frame 5. This effect is real-time and without delay. Moreover, after the entire mechanism is installed, there is no need to add special control harnesses, oil circuits, or other components, saving costs, eliminating complex control processes, and simplifying the overall structure.

[0045] Furthermore, to facilitate the winding of the first wire rope 21, such as... Figure 1 and Figure 2 As shown, in some embodiments, the goose head frame 5 is provided with a second pulley 52 and a third pulley 53 respectively. The first wire rope 21 passes through the second pulley 52, the first pulley group 51, the third pulley 53 and the first pulley 61 in sequence. The end of the first wire rope 21 near the first pulley 61 is fixed to the column 3.

[0046] Understandably, both the second pulley 52 and the third pulley 53 are fixed pulleys, both fixed to the gooseneck frame 5, changing only in direction and not moving with the working device 4. After the first wire rope 21 is led out by the main winch 2, it first passes through the second pulley 52, then through the first pulley group 51, then through the third pulley 53, and finally through the first pulley 61, fixing the end of the first wire rope 21 away from the main winch 2 to the column 3. This winding method is simple and facilitates the smooth winding and unwinding of the first wire rope 21.

[0047] Additionally, it should be noted that the specific number of the first pulley group 51 is not limited in the embodiments of the present invention. It can be understood that the first pulley group 51 may include multiple fixed pulleys, and multiple movable pulleys may be provided on the working device 4 to form a pulley group with the required ratio by winding the first wire rope 21 between the multiple fixed pulleys and the multiple movable pulleys in sequence.

[0048] like Figure 3 As shown, in some embodiments, the lever mechanism 6 includes a fixed frame 62 connected to the column 3 and a lever 631 hinged to the fixed frame 62 (e.g., ...). Figure 6As shown), the distance from the hinge point of lever 631 and fixed frame 62 to the rotation center of the first pulley 61 is L3, and the distance from the hinge point of lever 631 and fixed frame 62 to the output end is L4; the working device 4 is provided with a second pulley group, and the first wire rope 21 is wound between the first pulley group 51 and the second pulley group, so that 2N parallel rope segments for load bearing are formed between the working device 4 and the goose head frame 5, the distance from the rotation center of the first pulley group 51 to the center of the column 3 is L1, and the distance from the connection position of the back pull rope 7 and the goose head frame 5 to the center of the column 3 is L2, where N is the number of fixed pulleys in the first pulley group 51, and the following relationship exists:

[0049] .

[0050] In other words, once the structure of the first pulley block 51 is determined, there is a corresponding relationship between the ratio of L1 to L2 and the ratio of L3 to L4. By using the above formula to determine the appropriate ratio of lever 631, the bending moment balance of column 3 can be achieved, effectively improving the bending condition of column 3.

[0051] It is understandable that the first pulley block 51 and the second pulley block form a pulley block with a ratio of 2N. Let F1 be the tension in the first wire rope 21 acting on the working device 4, and F2 be the equivalent tension in the goose head frame 5 at the connection point with the back support rope 7. Then, under ideal conditions... At this time, the torque applied to the column 3 by the working device 4 through the first pulley block 51 is balanced with the torque applied to the column 3 by the back tension rope 7. Let F3 be the resultant force of the first wire rope 21 on the first pulley 61, and F4 be the tension at the output end of the lever mechanism 6. Then:

[0052]

[0053]

[0054]

[0055] Therefore, we can conclude that: .

[0056] For example, when N=6, that is, when the first pulley system 51 and the second pulley system form a 12-fold pulley system, when When, take It can make It is established. Conversely, by using the proportional relationship between L1 and L2, the proportional relationship between L3 and L4 can be reasonably designed, that is, the ratio between the input and output of lever 631 can be reasonably designed to achieve the bending moment balance of column 3.

[0057] In addition, such as Figure 4As shown, in some other embodiments, the force linkage between the input end of the lever mechanism 6 and the first wire rope 21 can also be achieved in the following way: the part of the first wire rope 21 located between the working device 4 and the first pulley group 51 includes a tension sensor 8; the machine body 1 or the column 3 is provided with a first adjusting cylinder 9; the first adjusting cylinder 9 is connected to the input end of the lever mechanism 6; the tension sensor 8 and the first adjusting cylinder 9 are respectively connected to the control device; the control device controls the output force of the first adjusting cylinder 9 according to the detection signal of the tension sensor 8.

[0058] In other words, this embodiment utilizes the tension sensor 8 to detect the tension of the first wire rope 21 in real time and feeds this tension back to the control device. The control device then controls the hydraulic pressure of the first adjusting cylinder 9, which acts on the input end of the lever mechanism 6. This, in turn, causes the back-pull rope 7 to generate tension, balancing the torque on the column 3. It can be understood that the control device adjusts the hydraulic pressure applied to the input end of the lever mechanism 6 by the first adjusting cylinder 9 based on the tension of the first wire rope 21, thus linking the force on the input end of the lever mechanism 6 with the tension of the first wire rope 21. This achieves tension feedback from the back-pull rope 7 to the first wire rope 21. This scheme can automatically control and adjust the balancing torque of the column 3, responding promptly to the torque generated by the load on the column 3 and achieving torque balance. It can be seen that this scheme avoids the first wire rope 21 bypassing the input end of the lever mechanism 6, making the winding of the first wire rope 21 simple and reliable.

[0059] It should be noted that this embodiment does not limit the specific method by which the control device adjusts the hydraulic pressure applied to the input end of the lever mechanism 6 by the first adjusting cylinder 9 based on the tension of the first wire rope 21. For example, during construction, the tension sensor 8 monitors the tension of the first wire rope 21 in real time, and the control device determines the magnitude of the tension of the first wire rope 21 compared to the preset pressure. When the tension of the first wire rope 21 meets the preset pressure requirement, it indicates that the tension of the first wire rope 21 is normal, and the current hydraulic pressure of the first adjusting cylinder 9 is maintained. When the tension of the first wire rope 21 increases, the hydraulic pressure of the first adjusting cylinder 9 is controlled and adjusted, thereby increasing the force applied by the first adjusting cylinder 9 to the input end of the lever mechanism 6, which in turn increases the tension of the back pull rope 7 and increases the balancing torque of the back pull rope 7 on the column; when the tension of the first wire rope 21 decreases, the hydraulic pressure of the first adjusting cylinder 9 is controlled and adjusted, thereby decreasing the force applied by the first adjusting cylinder 9 to the input end of the lever mechanism 6, which in turn decreases the tension of the back pull rope 7 and decreases the balancing torque of the back pull rope 7 on the column.

[0060] It should be noted that this embodiment does not limit the specific implementation of the connection between the first adjusting cylinder 9 and the input end of the lever mechanism 6, as long as the connection between the first adjusting cylinder 9 and the input end of the lever mechanism 6 can be achieved. For example, one end of the first adjusting cylinder 9 is hinged to the column 3, and the other end is directly hinged to the input end of the lever mechanism 6. This solution is simple. In other embodiments, the input end of the lever mechanism 6 may be provided with a first pulley 61, and one end of the first adjusting cylinder 9 may be connected to a second steel wire rope 64. The second steel wire rope 64 passes around the first pulley 61 and is fixed to the column 3 or the gooseneck frame 5. This solution can reduce the hydraulic pressure of the first adjusting cylinder 9, so that a larger back-pulling rope 7 can be obtained by outputting a smaller hydraulic pressure through the first adjusting cylinder 9.

[0061] In some embodiments, the back pull rope 7 is connected to the output end of the lever mechanism 6 and / or the goose head frame 5 via a length adjustment mechanism.

[0062] In other words, this embodiment adds a length adjustment mechanism between the back pull rope 7 and the output end of the lever mechanism 6 and / or between the back pull rope 7 and the goose head frame 5 to adjust the margin of the back pull rope 7, so that there is a suitable length of back pull rope 7 between the output end of the lever mechanism 6 and the goose head frame 5, preventing the back pull rope 7 from being too long or too short.

[0063] It should be noted that this embodiment does not limit the specific structure of the length adjustment mechanism, as long as it can adapt to the length of the back pull rope 7 and prevent the back pull rope 7 from being too long or too short. For example, the length adjustment mechanism is a telescopic mechanism; that is, this embodiment utilizes the telescopic mechanism to adapt to the length of the back pull rope 7. When the back pull rope 7 is too short, the telescopic mechanism extends; when the back pull rope 7 is too long, the telescopic mechanism retracts, thereby enabling the back pull rope 7 to be smoothly connected between the output end of the lever mechanism 6 and the goose head frame 5. Figure 5 As shown, in some embodiments, the length adjustment mechanism is a second adjusting cylinder 10. That is, in this embodiment, the second adjusting cylinder 10 is used to adjust the length of the back pull rope 7 to prevent the back pull rope 7 from being too long or too short.

[0064] Additionally, it should be noted that in this embodiment of the invention, the lever mechanism 6 is located on the body 1 or the column 3. When the lever mechanism 6 is located on the body 1, the weight and complexity of the column 3 can be minimized. As a moving component that needs to be frequently lifted, lowered, and pitched, removing the lever mechanism 6 from the column 3 can reduce the weight of the column 3, facilitate lifting the column 3, reduce the inertia of the column 3, and make the center of gravity of the equipment lower and the driving stability better. In addition, since the main winch 2 and other key mechanisms (such as the engine, hydraulic valve group or control room, etc.) are arranged on the body 1, it is convenient to centrally maintain the lever mechanism 6.

[0065] In addition, when the lever mechanism 6 is located on the column 3, in some embodiments, the lever mechanism 6 is located at the lower part of the column 3.

[0066] In other words, this embodiment does not place the lever mechanism 6 near the goose head frame 5, but rather at the lower part of the column 3. This arrangement effectively reduces the weight of the upper part of the column 3, bringing the weight of the lever mechanism 6 closer to the base of the column 3, thereby lowering the center of gravity and motion inertia of the equipment, and improving the stability and frequent lifting performance of the column 3. In addition, the back pull rope 7 comes down from the goose head frame 5 and connects directly to the output end of the lever mechanism 6. The input force from the first wire rope 21 is also directly transmitted to the lever mechanism 6, and the force flow forms a closed loop on the column 3, making the force flow path simple and efficient. Moreover, this solution facilitates the installation and maintenance of the lever mechanism 6.

[0067] Additionally, it should be noted that the specific structure of the lever mechanism 6 is not limited in the above embodiments.

[0068] like Figure 6 As shown, in some embodiments, the lever mechanism 6 includes a fixed frame 62 and a lever portion 63. The fixed frame 62 is connected to the column 3. The lever portion 63 includes two parallel levers 631 and a connecting portion 632 connecting the two levers 631. The two levers 631 are respectively hinged to the fixed frame 62. The connecting portion 632 includes at least two spaced first connecting portions 6321 and two spaced second connecting portions 6322. The input end is located between the two first connecting portions 6321, and the output end is located between the two second connecting portions 6322.

[0069] In other words, in this embodiment, the lever part 63 of the lever mechanism 6 is an integral frame structure, formed by multiple connecting parts 632 connecting two parallel levers 631. The input end is located between the two first connecting parts 6321, and the output end is located between the two second connecting parts 6322. For example, a support base 633 is provided between the two first connecting parts 6321, and the support base 633 is provided with a first pulley 61, which serves as the input end of the lever mechanism 6; or, a fixed base 634 is provided between the two second connecting parts 6322, which serves as the output end and is used to connect to the back pull rope 7 or the second adjusting cylinder 10. During operation, the lever part 63 rotates relative to the fixed frame 62, and the adjusting torque is balanced. In this design, the lever part 63 has high structural strength, good structural stability, and balanced force distribution.

[0070] In addition, it should be noted that the specific structure of the fixing frame 62 is not limited in this embodiment, as long as the fixing frame 62 can be connected to the column 3 or the body 1 and the lever part 63 is set.

[0071] In some embodiments, the fixing frame 62 includes a first fixing member 621 and a second fixing member 622 and a third fixing member 623 that are respectively connected to the first fixing member 621 and spaced apart. The ends of the second fixing member 622 and the third fixing member 623 away from the first fixing member 621 are connected to an end member 624. The end member 624 has an opening, and a lever portion 63 is disposed between the second fixing member 622 and the third fixing member 623, with the output end of the lever portion 63 extending out from the opening.

[0072] In other words, in this embodiment, the fixing frame 62 is a frame structure with an internal space. The first fixing member 621, the second fixing member 622, the third fixing member 623 and the end member 624 enclose the internal space, and the lever part 63 is disposed in the internal space to ensure that the lever part 63 can be an integral frame structure. For example, the two levers 631 of the lever part 63 are respectively hinged to the inner sides of the second fixing member 622 and the third fixing member 623. In addition, the output end of the lever part 63 extends from the opening of the end member 624 to ensure that the output end of the lever part 63 is connected to the back pull rope 7 or the second adjusting cylinder 10. Furthermore, the end member 624 is provided with an opening that is closed on all four sides.
