[0024] The power output module is used to drive the mechanical transmission module to drive the slide to slide along the slide rail.

[0025] In some embodiments, the mechanical transmission module is a sprocket chain structure, or the mechanical transmission module is a pulley belt structure, or the mechanical transmission module is a screw nut seat structure.

[0026] In some embodiments, the crane boom wire rope assembly equipment further includes: a supporting device, arranged between the two rope tensioning devices, for supporting the first boom section; and

[0027] An assembly trolley is arranged at one end of the supporting device and is used to transport the second arm section to be assembled along the second horizontal direction (X).

[0028] In a second aspect, the present application further provides a crane boom wire rope assembly method, which is applied to the crane boom wire rope assembly equipment provided according to the first aspect above. The crane boom wire rope assembly method comprises:

[0029] S100: placing the first boom section between the two rope tensioning devices and preparing two sets of steel wire ropes to be installed;

[0030] S200: driving the rope pulling mechanisms on both sides of the first boom section to move to the tail end of the first boom section, then arranging a group of steel wire ropes on both sides of the first boom section, and fixing the rope ends of the steel wire ropes to the rope pulling mechanisms;

[0031] S300: Assemble the second arm section into the first arm section and install the steel wire rope on the second arm section, and use the second arm section to bring the steel wire rope into the first arm section. At the same time, start the rope tensioning device, tighten the steel wire rope through the rope tensioning mechanism until the second arm section is assembled in place, stop the rope tensioning device, remove the rope end of the steel wire rope and install it to the tail of the first arm section.

[0032] As a further improvement of the above technical solution:

[0033] In some embodiments, step S300 includes:

[0034] S310: The second boom section is transported to the head end of the first boom section by an assembly trolley, and the steel wire rope is installed in the corresponding ear plates on both sides of the tail of the second boom section. The upper end is fixed to a dedicated rope support frame, and the lower end is tied and fixed to the lower side of the tail of the second boom section.

[0035] S320: Start the assembly trolley and install the second boom section into the first boom section. When the rope support frame contacts the head of the first boom section, stop the assembly trolley, remove the rope support frame, and place the steel wire rope into the pulley at the head of the first boom section.

The rope tensioning device is simultaneously started, and the rope pulling mechanism drives the steel wire rope to move toward the head of the first boom section. The movement speed of the rope pulling mechanism is slower than the movement speed of the assembly trolley.

[0038] S350: After the second boom section is assembled in place and the steel wire rope is also assembled in place, the operation of the rope tensioning device and the assembly trolley is stopped, and the rope end of the steel wire rope is removed and installed to the tail of the first boom section.

[0039] The present application provides a crane boom wire rope assembly device and assembly method. During wire rope assembly, the crane boom wire rope assembly device first places a first boom section between two tensioning devices, then transfers a second boom section to the first boom section. This allows the tensioning devices arranged on both sides of the first boom section to simultaneously pull the wire ropes on both sides. Specifically, during wire rope assembly, the ends of the wire ropes are connected to the end fixing assembly of the tensioning mechanism. A linear drive mechanism then drives the entire tensioning mechanism to move the wire rope in a first direction. During assembly of the first boom section and the second boom section, the tensioning devices pull the wire rope, ensuring that the wire rope remains in a tensioned state. Thus, the crane boom wire rope assembly device provided by the present application eliminates the need for manual wire rope pulling and prevents friction between the wire rope and the ground. This improves wire rope installation efficiency and makes the installation process safer and more reliable. Furthermore, it improves wire rope installation quality, avoids problems such as tangling or falling off a pulley, and ensures safety after installation.

[0052] The following describes the specific embodiments of the present application in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present application and are not intended to limit the present application.

[0053] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with exemplary embodiments.

[0054] See also Figure 1 , this embodiment provides a crane boom wire rope assembly device for assisting the installation of wire ropes in the crane boom.

[0055] In this embodiment, the crane boom wire rope assembly equipment includes two rope tensioning devices 100 arranged in a first horizontal direction Y. A space for accommodating the first boom section is formed between the two rope tensioning devices 100. This allows the first boom to be placed between the two rope tensioning devices 100, facilitating subsequent wire rope installation.

[0056] Furthermore, considering the fixing and positioning of the first boom section and the transportation of the second boom section to be assembled, the crane boom wire rope assembly equipment provided in this embodiment further includes a supporting device and an assembly trolley.

[0057] The support device is installed on the foundation and arranged between the two rope tensioning devices 100. The support device is used to support the first boom section, and the length direction of the supported first boom section is parallel to the second horizontal direction X. The support device also positions and fixes the first boom section, preventing displacement and rotation during assembly of the second boom section, which would affect assembly quality and efficiency, and ensuring safety and reliability. An assembly trolley is arranged at one end of the support device and is used to transport the second boom section to be assembled along the second horizontal direction X.

[0058] Therefore, a rope tensioning device 100 is provided on both sides of the support device along the second horizontal direction X, and the two rope tensioning devices 100 are arranged in a counter-positioned manner to achieve synchronous tensioning of the two groups of steel wire ropes on the left and right sides of the first arm section when assembling.

[0059] Please also refer to Figure 2 The following describes one of the two rope tensioning devices 100. The rope tensioning device 100 includes a linear drive mechanism 110 and a rope pulling mechanism 120. The rope pulling mechanism 120 is disposed at the output end of the linear drive mechanism 110 and is used to connect to the rope end of the steel wire rope to be assembled. The linear drive mechanism 110 is used to drive the rope pulling mechanism 120 to move along the second horizontal direction X.

[0060] As will be appreciated, the crane boom wire rope assembly equipment provided in this embodiment utilizes a support device to support the first boom section, an assembly trolley to transport the second boom section, and a rope tensioning device 100 disposed on either side of the support device to synchronously pull the wire ropes on both sides. During wire rope assembly, the ends of the wire ropes are connected to the rope tensioning mechanism 120, which is then driven by the linear drive mechanism 110 to move the rope tensioning mechanism 120 in a first direction. During the assembly process of the first and second boom sections, the rope tensioning device 100 pulls the wire rope, ensuring that the wire rope remains taut.

[0061] In this way, the crane boom wire rope assembly equipment provided in this embodiment, when installing the wire rope, on the one hand, improves the installation efficiency of the wire rope, and the installation process is safer and more reliable; on the other hand, it improves the installation quality of the wire rope, avoids problems such as the wire rope being tangled or falling off the pulley, and ensures safety of use after installation.

[0062] In order to more clearly describe the technical solution of the present application, the crane boom wire rope assembly equipment provided in this embodiment is described below.

[0063] See also Figure 1 and Figure 2 The above-mentioned rope pulling mechanism 120 includes a tensioning support 121, a tensioning cantilever 122 and a rope end fixing assembly 123. The tensioning support 121 is arranged at the output end of the linear drive mechanism 110. The tensioning cantilever 122 is arranged on the tensioning support 121 and extends along the first horizontal direction Y, wherein the first horizontal direction Y is perpendicular to the second horizontal direction X, so that the tensioning cantilever 122 can be parallel to the end face (head end or tail end) of the first arm section, which is convenient for subsequent pulling of the wire rope. The rope end fixing assembly 123 is arranged on the tensioning cantilever 122 and is used for detachable connection with the rope end of the wire rope. In this way, the linear drive mechanism 110 can drive the tensioning cantilever 122 and the rope end fixing assembly 123 to move synchronously along the second horizontal direction X by driving the tensioning support 121 to move, thereby realizing the pulling of the wire rope and keeping the wire rope in a tensioned state.

[0064] Furthermore, the rope end fixing assembly 123 includes a fixing frame 1230 and a fixing pin 1231. The fixing frame 1230 is disposed on the tensioning cantilever 122, and a receiving hole 1232 is formed between the fixing frame 1230 and the tensioning cantilever 122 for the rope end of the wire rope to pass through. One end of the fixing pin 1231 is a stopper, and the other end passes through the fixing frame 1230 and the receiving hole 1232 in sequence to be detachably connected to the tensioning cantilever 122. The rope end of the wire rope is provided with a pin hole for the fixing pin 1231 to pass through. Thus, when it is necessary to connect the rope end of the wire rope to the rope end fixing assembly 123, the fixing pin 1231 is first pulled out, the rope end of the wire rope is then placed in the receiving hole 1232, and the fixing pin 1231 is then sequentially inserted into the rope end of the wire rope to achieve a detachable connection. When the steel wire rope needs to be removed, it is only necessary to unplug the fixing pin 1231 and take out the rope end of the steel wire rope.

[0065] In this embodiment, the tensioning arm 122 is rotatably mounted on the tensioning support 121. For example, the tensioning arm 122 can be rotated from a 0° to a 90° position in the horizontal plane. In the 0° position, the tensioning arm 122 is located in a first horizontal direction Y, and in the 90° position, the tensioning arm 122 is located in a second horizontal direction X.

[0066] The rope pulling mechanism 120 further includes a rotation limiting plate 124 . The rotation limiting plate 124 is disposed on the tensioning support 121 and is used to limit the rotation of the tensioning cantilever 122 relative to the tensioning support 121 .

[0067] Specifically, the rotation limiting plate 124 is detachably mounted on the tensioning support 121 , and a limiting protrusion 1220 is provided on the tensioning cantilever 122 , which is configured to abut against the rotation limiting plate 124 , thereby limiting the rotation of the tensioning cantilever 122 .

[0068] Please also refer to Figure 3 The linear drive mechanism 110 includes a linear sliding assembly 111, a slide 112, and a drive assembly 113. The linear sliding assembly 111 includes a base 1110 and a slide rail 1111 disposed on the base 1110. Both ends of the slide rail 1111 extend along the second horizontal direction X. The slide 112 is slidably disposed on the slide rail 1111. The slide 112 is provided with a pull rope mechanism 120, that is, a fixing frame 1230 of the pull rope mechanism 120 is mounted on the slide 112. The drive assembly 113 is disposed on the base 1110 and connected to the slide 112, and is used to drive the slide 112 to slide along the slide rail 1111.

[0069] Drive assembly 113 includes a drive base 1130, a power output module 1131, and a mechanical transmission module 1132. Drive base 1130 is connected to base 1110; power output module 1131 is mounted on drive base 1130; mechanical transmission module 1132 is in driving connection with power output module 1131, and slide 112 is connected to mechanical transmission module 1132. Power output module 1131 drives mechanical transmission module 1132, which in turn drives slide 112 along slide rail 1111.

[0070] Optionally, the mechanical transmission module 1132 is a sprocket chain structure, or the mechanical transmission module 1132 is a pulley belt structure, or the mechanical transmission module 1132 is a screw nut seat structure.

[0071] Please also refer to Figure 4 and Figure 5In this embodiment, a sprocket chain structure is used as an example for description. The mechanical transmission module 1132 includes a sprocket mounting seat 1133, a driving sprocket 1134, a driven sprocket 1135, and a chain. The sprocket mounting seat 1133 is disposed at one end of the base 1110. The power output module 1131 is disposed on the sprocket mounting seat 1133 and can be an electric motor or a hydraulic motor. The driving sprocket 1134 is rotatably disposed on the sprocket mounting seat 1133 via a driving shaft 1136. The driving shaft 1136 is connected to the power output module 1131 through a gear transmission connection, a sprocket transmission connection, or a pulley transmission connection. The driven sprocket 1135 is rotatably arranged at the other end of the base 1110 along the second horizontal direction X through the driven shaft 1137. The chain is passed through the driving sprocket 1134 and the driven sprocket 1135, and the chain is fixedly connected to the slide 112. In this way, the chain drives the slide 112 to move along the slide rail 1111 during operation.

[0072] See also Figure 5 Furthermore, the mechanical transmission module 1132 also includes a tensioning assembly 114, which is arranged at one end of the base 1110 near the driven sprocket 1135 and is used to tension the chain to prevent it from becoming loose. The tensioning assembly 114 includes a tensioning seat 1140 and a bearing seat 1141. The tensioning seat 1140 is connected to the base 1110. A storage space for the driven sprocket 1135 is formed in the middle of the tensioning seat 1140, and the two side walls of the storage space are provided with elongated holes 1142 along the first horizontal direction. Removable bearing seats 1141 are provided on both sides of the tensioning seat 1140. The two ends of the driven shaft 1137 respectively pass through the corresponding elongated holes 1142 and engage with the bearings in the bearing seats 1141. In this way, the chain tension can be adjusted by adjusting the installation position of the bearing seat 1141 along the length direction of the elongated hole 1142.

[0073] It is understandable that the above description of the tensioning assembly 114 is also applicable to the mechanical transmission module 1132 of the pulley-belt structure.

[0074] In some embodiments, the driving component 113 may directly adopt a linear motor.

[0075] See also Figures 1 to 5 Furthermore, this embodiment also provides a crane boom wire rope assembly method. The crane boom wire rope assembly method is applied to the crane boom wire rope assembly device provided above.

[0076] The crane boom wire rope assembly method includes the following steps:

[0077] S100: Place the first arm section between the two rope tensioning devices 100 and prepare two sets of steel wire ropes to be installed.

[0078] S200: Drive the rope-pulling mechanism 120 on both sides of the first arm section to move to the tail end of the first arm section, and then arrange a group of steel wire ropes on both sides of the first arm section, and fix the rope ends of the steel wire ropes on the rope-pulling mechanism 120; before the operation, turn the tensioning cantilever 122 to the 0° position and lock it to facilitate the subsequent traction and tensioning of the steel wire ropes.

[0079] S300: Assemble the second arm section into the first arm section and install the wire rope on the second arm section. The second arm section brings the wire rope into the first arm section. At the same time, start the rope tensioning device 100 and tighten the wire rope through the rope pulling mechanism 120 until the second arm section is assembled in place. Stop the rope tensioning device 100 and remove the rope end of the wire rope and install it to the tail of the first arm section.

[0080] Specifically, the above step S300 includes the following steps:

[0081] S310: The second boom section is transported to the head end of the first boom section by the assembly trolley, and the wire rope is then installed in the corresponding ear plates on both sides of the tail of the second boom section. The upper end is fixed on a special rope support frame, and the lower end is tied and fixed to the lower side of the tail of the second boom section.

[0082] S320: Start the assembly trolley and install the second boom section into the first boom section. When the rope support frame contacts the head of the first boom section, stop the assembly trolley, remove the rope support frame, and put the wire rope into the pulley at the head of the first boom section. The order of the wire rope inside and outside the pulley must be consistent with the connection at the tail of the second boom section.

[0083] S330: Start the rope tensioning device 100, and the rope pulling mechanism 120 drives the steel wire rope to slide toward the tail of the first arm section, so that the steel wire rope fits tightly in the pulley groove located at the head of the first arm section.

[0084] S340: The assembly trolley is restarted, and the second boom section is further installed into the first boom section. The wire rope rolls along the pulley and moves toward the head of the first boom section. The rope tensioning device 100 is simultaneously activated, and the rope tensioning mechanism 120 drives the wire rope toward the head of the first boom section. The movement speed of the rope tensioning mechanism 120 is slower than that of the assembly trolley. As will be appreciated, during the assembly process, the thrust of the assembly trolley driving the second boom section is greater than the tensioning force exerted on the wire rope by the tensioning mechanism 120. The tensioning mechanism 120 provides reverse tension while moving, thus ensuring that the wire rope remains taut.

[0085] S350: After the second boom section and the wire rope are fully assembled, the rope tensioning device 100 and the assembly trolley are stopped, the wire rope end is removed, and the end is installed at the end of the first boom section. After assembly is complete, the tensioning arm 122 is swung to a 90-degree position, and assembly of other workpieces continues to prevent the tensioning arm 122 from interfering with subsequent assembly.

[0086] Compared with the prior art, the crane boom wire rope assembly equipment and assembly method provided in this embodiment also has the following advantages:

[0087] Changing the traditional manual operation of wire rope assembly in the truck crane industry, greatly reducing the operator's workload and improving wire rope assembly efficiency;

[0088] During the wire rope assembly process, the technical solution of this embodiment ensures that the wire rope is always taut by outputting reverse tensioning force. Compared with the existing technology of tensioning by manual pulling and the friction provided by the rope end contacting the ground, the tensioning quality of the wire rope is higher, which greatly reduces the quality failures of the wire rope being twisted and falling off the pulley, and improves the quality of wire rope assembly;

[0089] During the assembly process of the first boom section and the second boom section, the technical solution of this embodiment can control the linear drive mechanism 110 to output different wire rope tensioning forces to meet the needs of different products. Compared with the current method of ensuring tension by relying solely on the friction of the rope head against the ground or manual pulling, it is more precise and improves the quality of wire rope assembly.

[0090] In the technical solution of this embodiment, the steel wire ropes on the left and right sides of the first boom section can be tensioned synchronously, which is more efficient than the current manual tensioning of one side at a time by the operator. At the same time, the equipment in this solution can synchronously and stably output tensioning force to the steel wire ropes on both sides, ensuring that the tension of the steel wire ropes on the left and right sides is consistent.

[0091] In the technical solution of this embodiment, the tensioning process of the wire rope assembly operation is automatically completed by the equipment, and the operator does not need to pull it manually or walk back and forth, thus avoiding the safety hazard of falling into the work pit during the manual operation.
