Description

Technical Field

[0001] The invention belongs to the technical field of engineering machinery, and in particular relates to a rope pressing device and a rope pressing method. Background Art

[0002] The extension and retraction functions of the telescopic boom are mainly realized through the telescopic mechanism. The traction wire rope in the telescopic mechanism is an important traction force-bearing component. After installation, it needs to be compressed to eliminate its internal stress and ensure its tension. For telescopic boom truck cranes, the industry generally adopts the method of hoisting weights to compress the traction wire rope. Specifically, during the rope compression debugging process, the truck crane with the telescopic boom is first driven to an open area, and the boom is extended two to three sections. Then a certain weight of weight is hoisted on the boom. At this time, the traction wire rope in the boom is forced to tighten due to the weight of the weight. After maintaining the hoisting state for a certain period of time, the boom is retracted. If the retraction is smooth, it means that the rope compression is completed. However, this method of rope pressing with weights hoisted on the boom has several disadvantages. First, after the boom is loaded with weights, if the weight is found to be inappropriate, the only way to increase or decrease the weight is to replace the weights. However, each time the weights are replaced, the connection between the weights and the boom needs to be disassembled and reassembled, which is very troublesome. Second, the operator is required to manually control the hoisting process, which is inefficient and poses a safety hazard. Third, since the telescopic boom has been installed on the truck crane, this method can only be carried out outdoors, and outdoor operations are easily affected by rain, ice and snow, high temperature and other weather conditions. Fourth, if abnormal noise, shaking and other faults occur during the rope pressing process, it is very inconvenient to check since the telescopic boom has been installed on the truck crane.

[0039] The specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0040] The rope pressing device of the present invention will be described below with reference to the accompanying drawings.

[0041] like Figure 1 and Figure 2 As shown, the present invention provides a rope pressing device, which is mainly used to press the traction wire rope of the telescopic boom 2, and is characterized in that the rope pressing device includes:

[0042] A fixed base 1 is provided with a first mounting position and a second mounting position in a transverse direction, wherein the first mounting position is used for mounting a telescopic arm 2;

[0043] A hydraulic power source 3, used for connecting with the pipeline of the telescopic boom 2;

[0044] The pressing mechanism 4 is arranged at the second installation position and is used to abut against the telescopic end 21 of the telescopic arm 2;

[0045] The controller is configured to control the hydraulic power source 3 to drive the telescopic boom 2 to extend until it abuts against the pressing mechanism 4 and to control the hydraulic power source 3 to drive the telescopic boom 2 to press the pressing mechanism 4 .

[0046] After the traction wire rope is installed on the telescopic boom 2, the traction wire rope may be loose and have residual internal stress, so the traction wire rope needs to be pressed. When in use, first install the telescopic boom 2 on the fixed base 1 and align the telescopic end 21 with the top pressing mechanism 4, then connect the hydraulic power source 3 and the luffing mechanism pipeline inside the telescopic boom 2. At this time, the controller controls the hydraulic power source 3 to drive the telescopic boom 2 to extend and retract, and the hydraulic power source 3 drives the telescopic boom 2 to extend, so that the telescopic end 21 is pressed against the top pressing mechanism 4. At this time, due to the combined effect of the driving force provided by the hydraulic power source 3 and the reaction force of the top pressing mechanism 4, the traction force of the traction wire rope is forced to increase, and the traction wire rope is tightened. That is, the rope pressing device provided by the present invention only needs to control the hydraulic power source 3 to complete the rope pressing of the traction wire rope, and the operation is simple. During the rope pressing process, the pressing force required for different types of telescopic booms 2 will be different, and the rope pressing device in the present invention only needs to adjust the driving force of the hydraulic power source 3 to change the pressing force of the top pressing mechanism 4 on the telescopic end 21, which is very convenient. Moreover, the rope pressing device in the present invention is much smaller than the entire truck crane, so it can be operated indoors, and because the telescopic boom 2 is placed horizontally on the fixed base 1, if some debugging faults occur during the debugging process, it can be more convenient for the operator to check and repair.

[0047] It should be noted that the rope pressing device is mainly used to press the traction wire rope in the telescopic mechanism. The telescopic mechanism can be the telescopic mechanism in the telescopic boom 2 on the crane, or the telescopic mechanism in other engineering machinery such as aerial work vehicles and telescopic pump trucks. The fixed base 1 is a relatively broad concept, which can refer to the ground alone or a collection of multiple mounts. In actual products, the control of the hydraulic power source 3 is generally achieved through the control button on the operating table, that is, the controller is integrated on the operating table. After the telescopic boom 2 is placed in place, the operator only needs to perform rope pressing debugging on the operating table. This method is relatively safe and conforms to ergonomic planning.

[0048] like Figure 2 and Figure 3As shown, in the embodiment of the present invention, a latch 211 is provided on the telescopic end 21, and the pressing mechanism 4 includes a mounting support 41 extending in the vertical direction and an abutting seat 42 movably provided on the side of the mounting support 41 facing the first mounting position, and a clamping groove 43 opening toward the first mounting position is provided on the abutting seat 42, and the clamping groove 43 is used to clamp the latch 211. After the telescopic arm 2 is placed, the clamping groove 43 can be aligned with the latch 211, and the alignment means that after the telescopic end 21 is abutted against the pressing mechanism 4, the latch 211 extends into the clamping groove 43. During the rope compression debugging process, the force borne by the telescopic end 21 is generally large, and the telescopic end 21 is also provided with other important components such as a pulley 212. In order to ensure that the telescopic end 21 is subjected to uniform force and prevent the pulley 212 from being squeezed and deformed, a snap-in groove 43 is provided to be specifically used for snapping with the latch 211. The snap-in groove 43 is preferably tapered in outer width, and the groove width is greater than the diameter of the latch 211, so that the latch 211 is more convenient to snap in.

[0049] like Figure 2 and Figure 3 As shown, in an embodiment of the present invention, an abutment plate 411 extending in the front-to-back direction is provided on the mounting support 41, a screw rod 412 extending in the front-to-back direction is provided on the abutment plate 411, and an abutment seat 42 is movably provided on the screw rod 412. Since there are size differences between the telescopic arm 2, after the telescopic arm 2 is placed and installed on the fixed base 1, the clamping groove 43 and the latch 211 are misaligned in the front-to-back direction or the vertical direction, so it is necessary to set an adjustment mechanism to adjust the position of the abutment seat 42. In the present invention, by setting a screw rod 412 on the abutment plate 411, and then movably setting the abutment seat 42 on the screw rod 412, the abutment seat 42 can move forward and backward on the screw rod 412 to adjust the position of the abutment seat 42 in the front-to-back direction, thereby ensuring that the latch 211 and the clamping groove 43 are aligned front-to-back, wherein the screw rod 412 can be driven by a servo motor.

[0050] like Figure 2 and Figure 3As shown, in the embodiment of the present invention, the mounting support 41 includes a lifting base plate 413, a piston rod fixedly arranged on the lifting base plate 413 in the vertical direction, and a hydraulic lifting cylinder 414 sleeved on the piston rod, and the abutment plate 411 is arranged on the hydraulic lifting cylinder 414. Specifically, the lifting base plate 413 is welded or detachably connected to the fixed base 1, the piston rod is vertically arranged on the lifting base plate 413, the hydraulic lifting cylinder 414 is sleeved on the piston rod and can move vertically on the piston rod, and the abutment plate 411 is arranged on the hydraulic lifting cylinder 414. It has been mentioned above that the abutment seat 42 is aligned with the latch 211 front and back through the screw rod 412, and in order to achieve the alignment of the abutment seat 42 and the latch 211 in the vertical direction, the piston rod and the hydraulic lifting cylinder 414 are provided, that is, the rope pressing device in the present invention can ensure the alignment of the clamping groove 43 and the latch 211 through the hydraulic lifting cylinder 414 and the screw rod 412 when it is necessary to press the rope of different models of telescopic booms 2. The aforementioned forward and backward movement and vertical movement may also be achieved by other methods, such as slide rails, guide rails and slide grooves, rollers and guide rails, etc., which are not limited here one by one.

[0051] like Figure 2 and Figure 3 As shown, in the embodiment of the present invention, a pulley 212 is further provided on the telescopic end 21, the bolt 211 is connected and the two ends extend out of the pulley 212, the abutment seat 42 includes a first support plate 421 and a second support plate 422 arranged in parallel and spaced on the screw rod 412, an accommodation space 423 for the pulley 212 to extend into is formed between the first support plate 421 and the second support plate 422, and the ends of the first support plate 421 and the second support plate 422 are provided with a clamping groove 43 for respectively clamping the two ends of the bolt 211. By providing two clamping grooves 43 to respectively clamp the two ends of the bolt 211, it is ensured that the bolt 211 is subjected to uniform force, and by providing the accommodation space 423, the pulley 212 can be prevented from being crushed by the top pressing mechanism 4.

[0052] like Figure 1 and Figure 3 As shown, in the embodiment of the present invention, a mounting cavity 11 is provided on the second mounting position, and the pressing mechanism 4 further includes a pressing force bearing seat 44 provided on the side of the mounting support 41 facing away from the telescopic end 21, the mounting support 41 is used to be inserted into the mounting cavity 11 for installation, and the pressing force bearing seat 44 is used to abut against the side wall of the mounting cavity 11. Since the pressing mechanism 4 is aligned with the telescopic arm 2 in the transverse direction, in order to ensure the force bearing capacity of the pressing mechanism 4, a downwardly recessed mounting cavity 11 is provided on the fixed base 1, and then the pressing mechanism 4 is inserted into the mounting cavity 11 for installation, at which time the pressing force bearing seat 44 on the back will abut against the side wall of the mounting cavity 11, thereby increasing the force bearing capacity of the pressing mechanism 4. Of course, there are many other ways to increase the force bearing capacity of the pressing mechanism 4, such as welding reinforcing ribs.

[0053] like Figure 1 and Figure 3 As shown, in the embodiment of the present invention, the mounting support 41 is provided with a slide rail 415 extending in the vertical direction, and the top pressure bearing seat 44 is movably arranged on the slide rail 415. Specifically, the mounting support 41 includes a lifting base plate 413, a piston rod and a hydraulic lifting cylinder 414, and the hydraulic lifting cylinder 414 is provided with a vertically extending slide rail 415, and the top pressure bearing seat 44 abuts against the hydraulic lifting cylinder 414 and is clamped on the slide rail 415. The top pressure bearing seat 44 is a main force-bearing component, and its position relative to the fixed base 1 is fixed after installation. In order to facilitate the movability of the hydraulic lifting cylinder 414, the slide rail 415 can be arranged on the hydraulic lifting cylinder 414.

[0054] like Figure 3 As shown, in the embodiment of the present invention, an elastic pressing block 431 is further provided on the inner wall of the clamping groove 43, and the elastic pressing block 431 is used to abut against the latch 211. When the telescopic arm 2 is extended or retracted, in order to prevent the latch 211 from directly and rigidly contacting the clamping groove 43, thereby causing damage to the latch 211 or the clamping groove 43, the elastic pressing block 431 is provided to buffer the impact stress. The elastic pressing block 431 can be a rubber block, a wooden pad or some soft metal.

[0055] like Figure 1 As shown, in the embodiment of the present invention, the first fixing seat 12 and the middle second fixing seat 13 are sequentially arranged in the transverse direction on the first installation position, and the first fixing seat 12 and the second fixing seat 13 are used to sequentially support and fix the telescopic boom 2 in the transverse direction. Specifically, the telescopic boom 2 includes a plurality of telescopic boom sections that are sequentially connected, wherein the outermost telescopic boom 2 becomes the base arm, and the tail and middle of the base arm are provided with a latch 211 connection hole, the first positioning seat is used to support and fix the tail of the base arm, and the second positioning seat is used to support and fix the middle position of the base arm. Since the first fixing seat 12 and the second fixing seat 13 are sequentially arranged in the transverse direction, after the base arm is sequentially connected with the first fixing seat 12 and the second fixing seat 13, the extension direction of the telescopic boom 2 can be ensured, wherein the number of the second fixing seats 13 can be multiple, and multiple second positioning seats can make the installation and fixation of the telescopic boom 2 more stable.

[0056] It should be noted that the above-mentioned lateral direction, vertical direction, and front-to-back direction are only for illustrating the orientation of the telescopic arm 2 and the movement direction of the abutment 42, which are similar to the X, Y, and Z axes in the coordinate system. The lateral direction can refer to the horizontal direction or be slightly inclined. However, in order to facilitate inspection and maintenance by operators, the inclination angle needs to be ensured within an appropriate range to avoid one end being too high, making it difficult to climb and repair.

[0057] like Figure 1 and Figure 4As shown, in order to achieve the above-mentioned purpose, the present invention further provides a rope pressing method, wherein the rope pressing method uses the rope pressing device according to the above-mentioned method, and the rope pressing method comprises:

[0058] S10: Install the telescopic arm 2 on the fixed base 1 and align the telescopic end 21 of the telescopic arm 2 with the pressing mechanism 4 .

[0059] The above-mentioned alignment means that when the telescopic arm 2 is extended, the pin 211 can be accurately engaged in the engaging groove 43, that is, the alignment not only includes the alignment in the lateral direction, but also includes the alignment in the front-to-back direction and the vertical direction. In order to ensure the alignment, the telescopic arm 2 needs to be installed in place first so that the extension direction of the pin 211 is perpendicular to the groove depth direction of the engaging groove, and then the front-to-back alignment and the vertical alignment are achieved through the screw rod 412 and the hydraulic lifting cylinder 414.

[0060] S20: Start the hydraulic power source 3 to control the telescopic boom 2 to extend until it contacts the pressing mechanism 4.

[0061] The hydraulic power source 3 mainly refers to a hydraulic pump, wherein the control telescopic boom 2 is preferably to abut against the jacking mechanism 4 when the telescopic boom is extended to the 2-3 section boom.

[0062] S30: Control the telescopic boom 2 to apply pressure to the pressing mechanism 4 through the hydraulic power source 3, so that the oil pressure in the telescopic boom 2 is increased to a preset value and maintained for a preset time.

[0063] After the telescopic boom 2 contacts the pressing mechanism 4, it will no longer extend, and the hydraulic power source 3 continues to pressurize the telescopic boom 2. At this time, the pipeline oil pressure of the variable amplitude mechanism in the telescopic boom 2 will increase with the increase of the pressing force between the telescopic end 21 and the pressing mechanism 4. When the oil circuit pressure rises to a preset value, the pressure is maintained for a certain time. The time can be adjusted according to the size of the telescopic boom 2, generally 5-10 minutes. By maintaining the pressure for a certain time, the traction wire rope can be fully tightened. It should be noted that in the existing hydraulic system, valve control, pressure detection, and pipeline control are relatively common, so how the controller controls the hydraulic power source 3 will not be described in detail here.

[0064] S40: driving the telescopic arm 2 to retract and pulling the steel wire rope to complete the rope pressing.

[0065] At the same time, in actual operation, the rope pressing method of the present invention can be equipped with some detection instruments and sensors to display various parameters in real time, and the controller can perform automatic control based on these parameters. Taking one of the automatic control implementation methods as an example, the controller determines the model of the current telescopic boom 2 based on the boom model data and rope pressing data of the previous reservoir, and then controls the position movement of the top pressing mechanism 4 to align with the telescopic end 21. After alignment, it controls the operation of the hydraulic power source 3 and automatically performs the subsequent rope pressing steps.
