TECHNICAL FIELD
[0001] The present application relates to the technical field of material distribution machines, in particular to an automatic counterweight type bidirectional moving material distribution machine. BACKGROUND
[0002] A concrete distribution machine is a special engineering equipment for accurately conveying concrete to a construction pouring point by using a pumping and pipeline system. The concrete is pumped up by a concrete pump truck (ground pump or automobile pump) through a pipeline, conveyed to the rotating table of the distribution machine, and finally poured into the specified formwork, floor or any structure part to be poured through the rotating arm and the hose at the end.
[0003] In order to ensure the stability of the distribution machine during work, the entire machine base needs to be fixed. However, the position of the fixed distribution machine cannot be adjusted. After completing the work tasks within a working range, multiple workers need to disassemble and reassemble the distribution machine at another working position, which seriously affects the construction progress. In view of the above problems, the existing technology has a good solution. By adopting a bidirectional moving method, the distribution machine as a whole can move bidirectionally on a track or a pre-installed platform to expand its working range and ensure the progress of the project. However, there are still the following defects: In PC component production, long-line method platform production lines are widely used due to their high efficiency. The distribution machine matched with them usually moves above the long strip-shaped formwork along the fixed track and distributes materials. Since the distribution arm is arranged around the rotating table of the distribution machine and the discharging position is determined by the actual working scene, a counterweight block needs to be arranged on the distribution machine to ensure the stability of the distribution machine. However, the counterweight block is at a high position after the installation of the distribution machine, and the weight of the counterweight block cannot be changed at will. Therefore, the counterweight of the counterweight block must be designed according to the extreme working condition that the distribution arm is fully loaded and extends to the farthest end, resulting in serious redundancy of the counterweight in most non-extreme working conditions. In addition, when the distribution arm moves to the farthest end, the bending moment of the distribution arm itself and the concrete inside the distribution arm increases, thereby increasing the risk of overturning of the cross frame and affecting the construction progress.
[0004] Therefore, in order to solve the above problems, an automatic counterweight type bidirectional moving distribution machine is proposed. SUMMARY
[0005] The present application aims to provide an automatic counterweight type bidirectional moving distribution machine, which solves the problems of counterweight redundancy and the increase of bending moment of the distribution arm during movement to the farthest end, thereby increasing the risk of overturning of the cross frame and affecting the construction progress.

[0008] Preferably, the discharging assembly comprises a main pipe, a guide pipe, a hose, a secondary pipe, a mounting plate one and a mounting plate two, the main pipe is arranged through the vertical frame, the guide pipe is in L shape and two ends thereof are connected with the main pipe and the hose respectively, the secondary pipe is connected with the guide pipe through the hose, the hose is arranged in a hanging manner, the mounting plate one is arranged on the guide pipe, the mounting plate two is arranged on the secondary pipe, and the electric push rod is arranged in two and symmetrically arranged between the mounting plate one and the mounting plate two.
[0009] It can be known that the farther the secondary pipe for discharging is from the vertical frame, the greater the overturning moment generated is, and the weight of the secondary pipe increases in the process that the concrete raw material enters the secondary pipe and is discharged from the secondary pipe, further increasing the risk of overturning of the horizontal frame, although the risk of overturning of the horizontal frame in the discharging process can be reduced by increasing the counterweight at the other end of the horizontal frame, but the counterweight redundancy is increased, so the present scheme is adopted. By arranging the hose, the concrete can be normally conveyed while the hanging effect of the hose and the concrete in the hose are utilized to make part of the weight of the horizontal frame be distributed at the position close to the vertical frame, so as to reduce the risk of overturning of the horizontal frame.
[0010] Preferably, the counterweight assembly comprises a placing piece, a counterweight, a mounting frame, a support rod, a spool and a steel cable, the placing piece is arranged on the vertical frame, the counterweight is arranged on the placing piece, the mounting frame is fixedly arranged on the auxiliary pipe, the support rod is arranged through the mounting frame, the cross frame is provided with a U-shaped guide rod, the spool is arranged on the support rod and is connected between the cross frame and the U-shaped guide rod, the placing piece comprises a fixed block, a placing plate and a support wheel, the fixed block is fixedly sleeved on the vertical frame, the placing plate is rotatably arranged on the fixed block, the counterweight is arranged on the placing plate, and the support wheel is arranged on the base and is fixedly connected with the placing plate; the counterweight comprises an inner block, a middle block and an outer block which are sequentially movably sleeved, the inner block is limited to move within the middle block, the middle block is limited to move within the outer block, and the outer block is fixedly arranged on the placing plate to avoid separation of the outer block from the placing plate; the inner block is arranged at the end of the vertical section of the steel cable, the outer block is fixedly arranged on the placing piece, the length of the vertical section of the steel cable is greater than the length of the horizontal section in the full output state of the electric push rod, and the counterweight moment is greater than or equal to the overturning moment when the auxiliary pipe is in the most remote extreme load state, so that the stability of the auxiliary pipe and the cross frame is ensured.
[0011] It can be known that the cross frame is usually fixed with counterweights due to the high height, the overturning moment of the cross frame increases in the process that the electric push rod drives the auxiliary pipe away from the vertical frame, and if the counterweight is insufficient, the cross frame will be overturned, and if the counterweight is in the extreme working condition that the auxiliary pipe is fully loaded and extends to the most remote end, the counterweight will be redundant in the non-extreme working condition, so the scheme is adopted. By arranging the steel cable, the inner block, the middle block and the outer block, the inner block is lifted by the steel cable when the auxiliary pipe extends to the most remote end, and as the extension distance of the auxiliary pipe to the most remote end increases, the inner block lifts the middle block and the outer block in sequence in the lifting process, so that the counterweight at the other end of the cross frame is increased while the overturning moment of the cross frame is increased, the cross frame is prevented from being redundant in counterweight, and the safety is ensured when the overturning moment is increased.
[0012] Preferably, the guide assembly comprises a telescopic rod, a support block, a support rod and a guide wheel, the telescopic rod is arranged on the cross frame and is fixedly connected with the free end of the support block, a plurality of support plates are arranged on the support block, the support rod is arranged through the support plates, the guide wheel is arranged on the support rod, the steel cable is arranged on the guide wheel, and the height of the guide wheel is greater than or equal to the height of the spool.
[0013] It can be known that the bending moment of the right end of the auxiliary pipe gradually increases due to gravity during the extension to the farthest end, and the bending moment of the auxiliary pipe increases to cause great safety hazards and increase the overturning risk of the horizontal frame, although the rightmost position of the auxiliary pipe on the horizontal frame can be supported to increase the bending moment of the horizontal frame and also increase the overturning risk of the horizontal frame, so the scheme is adopted. The steel cable I, the guide wheel and the mounting frame are arranged above the pulley I to pull the auxiliary pipe by the steel cable I, which can reduce the moment of the auxiliary pipe gradually increasing when moving to the farthest end while automatically increasing the counterweight to reduce the overturning moment, and effectively reduce the overturning risk of the horizontal frame.

[0015] By adopting the above scheme, the push block can be driven by the steel cable II and the guide wheel II to move away from the vertical frame on the left side of the vertical frame during the movement of the auxiliary pipe to the farthest end, so as to further increase the counterweight of the horizontal frame, and the height of the guide wheel I is increased while the counterweight is further increased, which further reduces the bending moment of the auxiliary pipe when moving to the farthest end (in order to avoid that the steel cable I is blocked by the mounting plate I and the mounting plate II when the guide wheel I moves upward, the setting height of the guide wheel I can be greater than the setting height of the mounting plate I and the mounting plate II).
[0016] Compared with the prior art, the beneficial effects of the present application are:
[0017] 1. By arranging the steel cable I, the guide assembly and the counterweight assembly I, the movement track of the steel cable I can be limited by the guide effect of the guide assembly when the electric push rod drives the auxiliary pipe to move away from the main pipe, the counterweight of the other end of the horizontal frame can be automatically increased, and the guide assembly can cooperate with the steel cable I to have a hoisting effect on the auxiliary pipe when guiding the steel cable I, so as to reduce the bending moment of the auxiliary pipe on itself and the right end of the horizontal frame when moving away from the vertical frame, thereby reducing the overturning risk of the horizontal frame and effectively ensuring the construction progress.
[0018] 2、By setting the guide assembly and counterweight assembly two, the right end of the push block can be moved left in the process of moving the right pipe, thereby increasing the counterweight moment on the horizontal frame, and the height of the guide wheel one can be adjusted upward in the process of increasing the counterweight moment, increasing the hoisting effect of the steel cable one on the pipe, reducing the bending moment caused by the right end of the pipe and the horizontal frame during the right movement of the pipe, further reducing the overturning risk of the horizontal frame during automatic counterweighting, and further ensuring the construction progress.

Similarly, after the middle block 622 moves upward by a distance, the top of the middle block 622 is in contact with the inner wall of the top of the outer block 623, thereby further increasing the counterweight.

[0035] As one embodiment of the present invention, refer to Figure 1 , Figure 3 and Figure 6 The guide assembly 7 includes a telescopic rod 71, a support block 72, a second support rod 73, and a first guide wheel 74. The telescopic rod 71 is mounted on the cross frame 3 and its free end is fixedly connected to the support block 72. The support block 72 is provided with multiple support plates 721. The second support rod 73 is mounted through the support plate 721. The first guide wheel 74 is mounted on the second support rod 73. A first steel cable 66 is wound around the first guide wheel 74. The height of the first guide wheel 74 is greater than or equal to the height of the I-beam wheel 65.
[0036] Under the above-mentioned conditions, when the steel cable 66 is pulled and moves, it can be guided by the guide wheel 74, so that the steel cable 66 can only move along a fixed trajectory and reduce the friction force on the steel cable 66 during movement. It can also lift the support rod 64 above the support rod 64, reduce the bending moment caused by the secondary pipe 44 to itself and the cross frame 3 when it is far away from the main pipe 41, and further reduce the risk of the cross frame 3 overturning.
[0037] As one embodiment of the present invention, refer to Figure 1 , Figure 7 and Figure 8 The second counterweight assembly 8 is mounted on the crossbeam 3 and connected to the discharge assembly 4 and the guide assembly 7. The second counterweight assembly 8 includes a connecting frame 81, a second guide wheel 82, a push block 83, a second steel cable 84, and a top block 85. The connecting frame 81 is mounted on the first support rod 64. The second guide wheel 82 is mounted on the fixed end of the telescopic rod 71. The push block 83 is mounted on the crossbeam 3. The second steel cable 84 passes through the push block 83 and is wound around the second guide wheel 82. The two ends of the second steel cable 84 are connected to the connecting frame 81 and the push block 83, respectively. The bottom of the support block 72 is provided with a top groove 722.

[0038] In the above setting condition, when the auxiliary pipe 44 moves away from the main pipe 41, the connecting frame 81 will move synchronously with the mounting frame 63 and the auxiliary pipe 44, thereby pulling the steel cable II 84, which will pull the push block 83 through the guide wheel II 82, so that the push block 83 moves away from the vertical frame 2 from the other end of the horizontal frame 3, and in the process of moving away from the vertical frame 2, the top block 85 arranged thereon will press the supporting block 72, so that the supporting block 72 moves upward, increasing the height of the guide wheel I 74, that is, increasing the lifting height of the auxiliary pipe 44, thereby further reducing the bending moment caused by the auxiliary pipe 44 to itself and the horizontal frame 3 when moving away from the main pipe 41, and at the same time, the push block 83 moving away from the vertical frame 2 can increase the counterweight of the end of the horizontal frame 3 away from the auxiliary pipe 44, further reducing the risk of overturning of the horizontal frame 3 during work.
[0039] Working principle:
[0040] Before the loading operation, start the electric push rod 5 to adjust the position of the auxiliary pipe 44;
[0041] Since the mounting frame 63 is connected with the output end of the electric push rod 5 through the mounting plate II 46 and the auxiliary pipe 44 in sequence, when the output end of the electric push rod 5 drives the mounting plate II 46 to move right, the mounting frame 63 will move right synchronously, and in the process of moving right, the supporting rod I 64 arranged thereon will directly pull the steel cable I 66, which will adjust the moving direction through the guide wheel I 74 and pull the inner block 621 directly connected thereto when being pulled, so that the inner block 621 moves upward after being pulled, thereby automatically increasing the counterweight, and with the continuous right movement of the auxiliary pipe 44, the outer block 623 will be lifted in the process of the upward movement of the inner block 621, thereby further increasing the counterweight, and with the right movement of the auxiliary pipe 44, the connecting frame 81 arranged on the supporting rod I 64 will pull the steel cable II 84, and the other end of the steel cable II 84 will pull the push block 83 through the guide of the guide wheel II 82, so that the push block 83 moves away from the vertical frame 2 from the left end of the vertical frame 2, thereby further automatically increasing the counterweight, and in the process of the left movement of the push block 83, the top block 85 arranged thereon will move left synchronously with the push block 83 and press the supporting block 72, which will move upward under the action of the top groove 722 on the supporting block 72 and the slope of the top block 85, thereby increasing the height of the guide wheel I 74 arranged thereon, so that the counterweight automatically increased on the vertical section of the steel cable I 66 can have a lifting effect on the supporting rod I 64, reducing the bending moment caused by the auxiliary pipe 44 to itself and the horizontal frame 3 when moving away from the main pipe 41, thereby reducing the risk of overturning of the auxiliary pipe 44 and the horizontal frame 3;
[0042] Conversely, when the output end of the electric push rod 5 drives the installation plate two 46 to move left, the inner block 621, the middle block 622 and the push block 83 will all perform a reset movement, thereby automatically lowering the counterweight, avoiding the situation of counterweight redundancy, and the weight of the inner block 621 will pull the steel cable one 66 to exert pressure on the guide wheel one 74, the guide wheel one 74 will exert pressure on the support block 72 through the transmission of force, the support block 72 will be pressed to extrude the top block 85, so that the push block 83 moves right to reset, until the push block 83 is blocked by the main pipe 41, at this time the electric push rod 5 is in a retracted state, and the inner block 621 is located on the surface of the placement plate 612, ensuring that the push block 83 can move left to weight again when the subsequent auxiliary pipe 44 moves right.
