Description

Technical Field

[0001] This invention relates to a front outrigger assembly system for a concrete pump truck, belonging to the field of pump truck assembly technology. Background Technology

[0002] Currently, the common forms of front outriggers for concrete pump trucks are telescopic outriggers (X-legs) and curved outriggers (C-legs). However, since telescopic outriggers only need to move along a straight line to the support position to provide stable support, they save more space and area compared to curved outriggers. Therefore, telescopic outriggers (X-legs) are more common in the market. So, the following front outriggers refer to all telescopic outriggers (X-legs).

[0003] In the industry, the assembly of front outriggers mostly involves using an overhead crane to lift each outrigger section and place it on an assembly table for alignment and insertion. This is followed by the installation of the outrigger vertical cylinders. The entire assembly process, from incoming parts transfer to outrigger insertion and the final placement of the outrigger assembly, requires the involvement of an overhead crane. The frequent use of the crane makes the entire assembly process extremely inefficient. Using the crane for retrieval is not only difficult to operate but also prone to safety accidents. Furthermore, there is no truly effective positioning method during the alignment and insertion process, requiring manual assistance from the overhead crane throughout the assembly. Additionally, after the front outrigger assembly is completed, it needs to be transferred to the outrigger buffer area.

[0004] The assembly process of the front outriggers of concrete pump trucks urgently needs to be automated to ensure smooth coordination between various mechanisms and achieve the required linear assembly standards for the entire operation. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a concrete pump truck front outrigger assembly system. This system optimizes the existing front outrigger assembly process by establishing an outrigger conveyor line and using assembly and tilting mechanisms to replace the hoisting process, thereby ensuring the continuity of front outrigger production and meeting the needs of multiple pump truck products, thus improving the linear assembly capability of the outriggers.

[0006] To achieve the above objectives, the present invention is implemented using the following technical solution: a concrete pump truck front outrigger assembly system, wherein the front outrigger includes a Class I outrigger and a Class II outrigger, and includes a Class I outrigger conveying line, a Class II outrigger conveying line, and an outrigger buffer conveying line;

[0007] The Class I outrigger conveyor line is divided into a front section and a rear section. The front section is used to transport the Class I outriggers, and the rear section is used to transport the outrigger assembly. A second transfer mechanism is provided below the Class I outrigger conveyor line. The second transfer mechanism is used to transfer the Class I outriggers and the outrigger assembly.

[0008] The end of the Level II support leg conveyor line is provided with an assembly mechanism. The assembly mechanism can drive the Level II support leg to approach or move away from the junction of the front and rear sections of the Level I support leg conveyor line, and insert the Level II support leg into the Level I support leg to assemble it into a support leg assembly.

[0009] The outrigger buffer conveyor line is connected to the rear section of the Class I outrigger conveyor line and is used to convey the outrigger assembly to the outrigger buffer area.

[0010] Optionally, it also includes a first transfer mechanism for transferring the Class II outrigger from the Class II outrigger conveyor line to the assembly mechanism, the first transfer mechanism being disposed between the Class II outrigger conveyor line and the assembly mechanism.

[0011] Optionally, the first transfer mechanism includes a guide rail and a slide seat mounted on the guide rail. The slide seat can move back and forth on the guide rail and has a support above it. The connecting rods on both sides of the support are provided with sliding grooves. A transfer frame is fitted on the sliding grooves. The transfer frame is connected to the telescopic shaft of a cylinder mounted on the slide seat and can move up and down on the sliding grooves under the drive of the cylinder.

[0012] Optionally, the assembly mechanism includes a guide rail and a slide on the guide rail. The slide is provided with a lifting seat. A hydraulic cylinder is provided at the end of the lifting seat away from the first-stage support leg conveyor line. The hydraulic cylinder is used to push the second-stage support leg into the first-stage support leg. Both ends of the lifting seat are provided with clamping devices, which are used to center and clamp the second-stage support leg.

[0013] Optionally, the second transfer mechanism includes a guide rail and a slide seat disposed on the guide rail. The slide seat is provided with a lifting seat, and the lifting seat is provided with multiple clamping devices. The clamping devices are used to center and clamp the Class I outrigger or outrigger assembly.

[0014] Optionally, the clamping device includes a clamp, a first motor, and a lead screw connected to the first motor. The two ends of the lead screw are provided with threads in opposite directions of rotation. The clamp is respectively sleeved on both ends of the lead screw and threadedly connected to the lead screw.

[0015] Optionally, the lifting seat includes a telescopic column and a support frame driven by a second motor. Multiple telescopic columns are provided, with one end connected to the slide and the other end connected to the support frame.

[0016] Optionally, the slide includes a support plate, and gears driven by a third motor are provided at the four corners of the bottom of the support plate. The gears mesh with the guide rail and can drive the slide to move on the guide rail.

[0017] Optionally, a flipping mechanism is included, which is located at the junction of the rear section of the Class I support leg conveyor line and the support leg buffer conveyor line. The flipping mechanism includes a fourth motor, a pinion gear, and a clamping disk. Multiple clamping disks are provided and connected to each other by connecting rods. The fourth motor is located on the conveyor line, and its output shaft extends to the bottom of the conveyor line and is connected to the pinion gear. The pinion gear meshes with the teeth on a clamping disk.

[0018] Optionally, the clamping disc has a circular side, and each clamping disc has a slot at a symmetrical position, the slot being adapted to the support leg assembly.

[0019] Compared with the prior art, the beneficial effects achieved by the present invention are as follows:

[0020] This invention establishes an outrigger conveyor line, which operates in an assembly line manner from the source, ensuring the continuity of outrigger production and improving the linear assembly capability of outriggers; the coordinated use of the assembly mechanism and the transfer mechanism eliminates the original assembly method of using a crane to lift and move the alignment, solves the problem of difficult alignment of multi-stage outrigger insertion, and ensures the safe and orderly production process.

[0021] After the entire outrigger assembly is completed, the outrigger assembly is flipped off the production line by the flipping mechanism and transported into the outrigger buffer area through the outrigger buffer conveyor line. This completes the effective connection between the assembly and insertion of each level of outrigger and the flipping and hoisting of the outrigger after assembly in the buffer area. This ensures the speed and efficiency of the entire production process and successfully makes the linear assembly of the front outriggers of concrete pump trucks a reality. The entire assembly process is more linear and intelligent. Attached Figure Description

[0033] Example 1:

[0034] The front outriggers of a concrete pump truck include Class I outriggers 11 and Class II outriggers 12. The front outriggers can be divided into two-section outriggers or three-section outriggers. Therefore, Class II outriggers 12 here refer to Class II outriggers of two-section outriggers or a combination of Class II and Class III outriggers of three-section outriggers.

[0035] like Figure 1 As shown, the concrete pump truck front outrigger assembly system provided in this embodiment of the invention includes a Class I outrigger conveying line 1, a Class II outrigger conveying line 2, and an outrigger buffer conveying line 14.

[0036] The Class I outrigger conveyor line 1 is divided into a front section and a rear section. The front section is used to transport the Class I outriggers 11, and the rear section is used to transport the outrigger assembly 13. The outrigger assembly 13 is the outrigger combination after the Class I outriggers 11 and Class II outriggers 12 have been installed. A second transfer mechanism 5 is provided below the Class I outrigger conveyor line 1. The second transfer mechanism 5 is used to transfer the Class I outriggers 11 and the outrigger assembly 13.

[0037] An assembly mechanism 4 is provided at the end of the Class II support leg conveyor line 2, and a first transfer mechanism 3 is provided below it. The Class II support leg 12 can be transferred from the conveyor line to the assembly mechanism 4. Then the assembly mechanism 4 can drive the Class II support leg 12 to approach or move away from the junction of the front and rear sections of the Class I support leg conveyor line 1, and insert the Class II support leg 12 into the Class I support leg 11 to assemble it into a support leg assembly 13.

[0038] Guide rails 10 are provided below the Class I outrigger conveyor line 1 and Class II outrigger conveyor line 2, as well as below the assembly mechanism 4, to facilitate the movement of the first transfer mechanism 3, the second transfer mechanism 5, and the assembly mechanism 4. The outrigger buffer conveyor line 14 is connected to the rear section 102 of the Class I outrigger conveyor line and is used to transport the outrigger assembly 13 to the outrigger buffer area.

[0039] Example 2:

[0040] Combination Figures 3-4 Based on Embodiment 1, the first transfer mechanism 3 of this embodiment includes a slide 8 mounted on the guide rail 10, and a bracket 31 mounted above the slide 8. The bracket 31 is in the shape of an inverted U-shape, but is not limited to this; other suitable shapes are also acceptable. Slide grooves 32 are provided on the vertical connecting rods on both sides of the bracket 31. The transfer frame 33 is correspondingly fitted onto the slide grooves 32, allowing the transfer frame 33 to slide up and down along the slide grooves 32. Simultaneously, the transfer frame 33 is also connected to the telescopic shaft of the cylinder 34 mounted on the slide 8. The cylinder 34 is used to drive the transfer frame 33 to rise and fall, thereby adjusting the height of the secondary support leg 12.

[0041] Combination Figures 2-3The assembly mechanism 4 in this embodiment also includes the slide 8 described above. The slide 8 is provided with a lifting seat 7. Both ends of the lifting seat 7 are provided with clamping devices 6 for centering and clamping the second-stage support leg 12. At one end away from the first-stage support leg conveying line 1, a hydraulic cylinder 41 is provided. Driving the hydraulic cylinder 41 can push the second-stage support leg 12 into the first-stage support leg 11 to complete the insertion assembly.

[0042] Combination Figure 5 The second transfer mechanism 5 in this embodiment also includes the slide 8 and the lifting seat 7. The lifting seat 7 is provided with a plurality of clamping devices 6 for the first-level outrigger 11 or outrigger assembly 13. The number used in this embodiment is 2, but it is not limited to this. Any number that can perform centering and clamping operations on the outrigger should be possible.

[0043] Example 3:

[0044] Based on Example 2, combined with Figure 5 The clamping device 6 in this embodiment includes clamps 63, a first motor 61, and a lead screw 62 connected to the first motor 61. The lead screw 62 is divided into two sections, with threads in opposite directions of rotation on the two sections. There are two clamps 63, which are respectively sleeved on both ends of the lead screw 62 and threadedly connected to the lead screw 62. In this way, when the first motor 61 drives the lead screw 62 to rotate, the clamps 63 are controlled to move towards the center or separate to both sides through the threads in opposite directions of rotation, so as to achieve the centering and clamping of the support leg.

[0045] Combination Figure 2 In this embodiment, the slide 8 includes a support plate 81. The four corners of the bottom of the support plate 81 are provided with gears 83 driven by a third motor 82. The third motor 82 is mounted on the support plate 81. The gears 83 mesh with the guide rail 10. The rotation of the gears 83 can drive the slide 8 to move on the guide rail 10.

[0046] The lifting platform 7 in this embodiment includes telescopic columns 72 driven by a second motor 71 and a support frame 73. Multiple telescopic columns 72 are provided, with their lower ends connected to the slide 8. In this embodiment, the telescopic columns 72 are located at the four corners of the upper surface of the support plate 81 of the slide 8, but this is not a limitation; other suitable positions and quantities are also acceptable. The upper ends of the telescopic columns 72 are connected to the lower surface of the support frame 73, which supports the outriggers. Driven by the second motor 71, the telescopic columns 72 extend and retract, causing the support frame 73 to rise and fall.

[0047] Example 4:

[0048] Combination Figures 6-7Based on Embodiment 1, this embodiment also includes a flipping mechanism 9. The flipping mechanism 9 is located at the junction of the rear section 102 of the first-level support leg conveyor line and the support leg buffer conveyor line 14. The flipping mechanism 9 is used to flip and transfer the support leg to the support leg buffer conveyor line 14, and then transport it to the support leg buffer area through the support leg buffer conveyor line 14. This is mainly because the support leg is flipped and placed for buffering, which is convenient for subsequent use and can also make the spacing between the support legs as small as possible, so as to buffer more workpieces.

[0049] The flipping mechanism 9 includes a fourth motor 91, a pinion 92, and a clamping disc 93. There are multiple clamping discs 93, and in this embodiment, there are two clamping discs 93. Each clamping disc 93 is connected by a connecting rod 94. The side of the clamping disc 93 is circular, and each clamping disc 93 has a slot 931 at a symmetrical position. The slot 931 is adapted to the support leg assembly 13, and clamping structures are provided on both sides of the slot 931 to effectively clamp the support leg. The peripheral edge of the clamping disc 93 on one side is provided with teeth. The teeth mesh with the pinion 92. The pinion 92 is connected to the output shaft of the fourth motor 91. The fourth motor 91 drives the pinion 92 to rotate, and the meshing of the teeth can drive the clamping disc 93 to rotate, ultimately realizing the flipping and transfer of the support leg.

[0050] The working principle of this invention is as follows: First-stage support leg 11 and second-stage support leg 12 are placed on their respective conveyor lines. If the support leg is a three-section leg, it needs to be manually assembled beforehand. Then, the first-stage support leg conveyor line 1 and the second-stage support leg conveyor line 2 are started to move the support legs forward.

[0051] When the second-stage support leg 12 moves to the end of the second-stage support leg conveyor line 2, the cylinder 34 is activated. The cylinder 34 drives the transfer frame 33 to move upward, lifting the first second-stage support leg 12. Then, the slide 8 of the first transfer mechanism 3 moves towards the assembly mechanism 4 under the drive of the third motor 82. After reaching above the assembly mechanism 4, the transfer frame 33 moves downward, placing the second-stage support leg 12 on the assembly mechanism 4. Next, the clamping devices 6 at both ends of the assembly mechanism 4 are activated. The clamps 63 of the clamping devices 6 move towards each other, centering and clamping the second-stage support leg 12.

[0052] At the same time, when the first-stage support leg 11 moves to the end of the first-stage support leg conveyor line 101, the lifting seat 7 of the second transfer mechanism 5, which has been moved below it, moves up to lift the first-stage support leg 11. Similarly, the clamping device 6 on the second transfer mechanism 5 is activated to center and clamp the first-stage support leg 11.

[0053] Next, by adjusting the position and height of the second transfer mechanism 5, the first-stage support leg 11 and the second-stage support leg 12 on the assembly mechanism 4 are brought to the same horizontal line. Then, the assembly mechanism 4 is driven to move, causing the second-stage support leg 12 to be inserted into the first-stage support leg 11. After the insertion is completed, the second transfer mechanism 5 moves down, the clamping device 6 is released, and the support leg assembly 13 is placed back on the rear section 102 of the first-stage support leg conveyor line, so that it is conveyed forward with the conveyor line.

[0054] Next, drive the second transfer mechanism 5 to move in front of the tilting mechanism 9, and start the second transfer mechanism 5 to move upward again, lifting the first outrigger assembly 13 so that it is on the same horizontal line as the slot 931 of the tilting mechanism 9. Then, clamp it with the clamping device 6. Then, the second transfer mechanism 5 moves towards the tilting mechanism 9 to put the outrigger assembly 13 into the slot 931. After placement, start the tilting mechanism 9 to tilt and transfer the outrigger assembly 13 to the outrigger buffer conveyor line 14. Finally, it is transported to the outrigger buffer area through the outrigger buffer conveyor line 14. This operation is repeated to complete the assembly and transportation of all the front outriggers of the concrete pump truck.

[0055] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
