Description

Technical Field

[0001] This utility model belongs to the field of concrete pump truck technology, and specifically relates to a long-distance controlled concrete spraying device. Background Technology

[0002] A concrete pump truck is a machine that uses pressure to continuously transport concrete along a delivery pipe to the pouring point. It consists of a vehicle body (truck), a pump body, and a delivery pipe.

[0003] The vehicle body transmits the engine's power to the hydraulic pump unit or the rear axle through the power transfer box. The hydraulic pump unit or the rear axle drives the piston to drive the pump body to work, and uses the placing boom and delivery pipe installed on the vehicle body to deliver concrete to the pouring point.

[0004] Chinese utility model patent CN217268910U discloses a concrete pump truck nozzle control device, which includes: an operating linkage and a fixing clamp for clamping and fixing on the concrete pump truck nozzle. One end of the operating linkage is movably connected to the fixing clamp. After connecting the fixing clamp and the operating linkage, the position of the concrete pump truck nozzle can be adjusted in multiple directions and angles by pushing and pulling the operating linkage. The concrete pump truck nozzle control device is easy and quick to assemble and disassemble from the concrete pump truck nozzle, has strong clamping stability, can realize remote operation, and ensures the personal safety of the operator.

[0005] Although the solution disclosed in the aforementioned utility model patent allows workers to easily adjust the position and / or orientation of the concrete pump truck nozzle by operating the linkage at a certain distance from the nozzle, when installing the fixing clamp, one worker needs to approach the concrete pump truck nozzle and use the latch to fix it. At this time, this worker is next to the concrete pump truck nozzle, while another worker operates the pump in the cab. If the two workers do not communicate properly, or if the worker in the cab makes an operational error, concrete may be sprayed out from the concrete pump truck nozzle, which could easily cause the worker next to the nozzle to be splashed with concrete, posing a certain safety hazard.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] In the embodiments of this application, such as Figures 1 to 7As shown, the remote-controlled concrete spraying equipment includes a concrete pump truck 1 and a stationary assembly 2. (See attached image) Figure 1 ;in, The concrete pump truck 1 includes a delivery pipe 13 for conveying concrete; The fixing component 2 includes a semi-circular locking block 21, a rotating shaft 22, and a clamping device 23; there are two semi-circular locking blocks 21, and the hinge ends of the two semi-circular locking blocks 21 are rotatably mounted on the rotating shaft 22, and the openings of the two semi-circular locking blocks 21 are opposite to each other; the two ends of the clamping device 23 are a control end and a linkage end, respectively, and the distance between the linkage end and the control end is greater than or equal to 3m, and the linkage end is connected to the movable ends of the two semi-circular locking blocks 21; The operation control terminal controls the linkage terminal to move the movable ends of the two semi-arc blocks 21 closer or separate, thereby clamping or releasing the conveying pipe 13.

[0031] Before concrete pouring is required, the workers will send the delivery pipe 13 above the pouring point so that the concrete pump truck 1 can deliver the concrete to the pouring point through the delivery pipe 13. To prevent the output end of the delivery pipe 13 from swinging due to pressure during the pouring process (continuous delivery of concrete to the pouring point), a worker can hold the fixing component 2 and use the fixing component 2 to fix the output end of the delivery pipe 13. Specifically, the worker holds the control end of the clamping device 23, moves the two semi-circular blocks 21 closer to the delivery pipe 13, and puts the two semi-circular blocks 21 into the delivery pipe 13 from the output end of the delivery pipe 13. Then, by controlling the linkage end of the clamping device 23 through the operation control terminal, the movable ends of the two semi-arc blocks 21 are brought closer to the center to achieve clamping of the output end of the conveying pipe 13. Subsequently, another worker starts the delivery pump 112 in the concrete pump truck 1. The concrete in the concrete storage bin 111 is extracted by the delivery pump 112 and continuously delivered to the pouring point through the delivery pipe 13. During this process, the worker holding the clamping device 23 can fix the output end of the delivery pipe 13 within a certain distance range (greater than or equal to 3m) through the clamping device 23 to prevent the output end of the delivery pipe 13 from swinging due to pressure during the concrete pouring process.

[0032] In addition, the operator holding the clamping device 23 can also adjust the orientation of the output end of the conveying pipe 13 through the clamping device 23, and can adjust the position of the output end of the conveying pipe 13 in multiple directions and angles to better meet the concrete pouring requirements.

[0033] In some embodiments, the clamping device 23 described above includes a connecting rod 231, a hinge seat 232, a limiting sleeve 233, an internally threaded cylinder 234, and a gripping handle 235. See also Figure 2 and Figure 3 ;in, There are two connecting rods 231, one end of which is hinged to the movable end of two semi-circular locking blocks 21. The portions of the two connecting rods 231 away from the semi-circular locking blocks 21 are bent inward. In this embodiment, the angle between the portion of the connecting rod 231 away from the semi-circular locking blocks 21 and the connecting rod 231 itself is 135°. See [reference needed]. Figure 2 Furthermore, the ends of the two connecting rods 231 away from the semi-circular locking block 21 are both hinged to the hinge seat 232, and the rotation axes at both ends of the connecting rods 231 are parallel to the rotation axis of the rotating shaft 22. The inner diameter of the limiting sleeve 233 is greater than or equal to the inner diameter of the internal threaded cylinder 234, and the limiting sleeve 233 and the internal threaded cylinder 234 are coaxially connected. A connecting screw 236 is provided in the internal threaded cylinder 234. One end of the connecting screw 236 passes through the limiting sleeve 233 and is connected to the side of the hinge seat 232 away from the connecting rod 231. When the internal threaded cylinder 234 is rotated, the connecting screw 236 will extend outward or retract inward under the action of the thread. The grip handle 235 is located at the end of the internal threaded cylinder 234 away from the limiting sleeve 233. The grip handle 235 is the control end of the clamping device 23. The end of the connecting rod 231 connected to the semi-arc block 21 is the linkage end of the clamping device 23. During use, the operator can rotate the handle 235 to move the hinge seat 232 towards the inner threaded cylinder 234 under the action of the connecting screw 236 and into the limiting sleeve 233. At this time, the connecting rod 231 will be constrained by the limiting sleeve 233, so that the end of the connecting rod 231 that is hinged to the semi-arc block 21 can drive the movable end of the semi-arc block 21 to move closer to the center and fit together, so that the two semi-arc blocks 21 can clamp the output end of the conveying pipe 13 and realize the clamping of the conveying pipe 13. When it is necessary to remove the fixing component 2, the operator can rotate the grip handle 235 in the opposite direction (opposite to the twisting direction during the clamping process) to move the hinge seat 232 away from the internal threaded cylinder 234. At this time, the end of the connecting rod 231 away from the semi-circular locking block 21 and the hinge seat 232 will be moved out of the limiting sleeve 233, and the constraint of the limiting sleeve 233 on the connecting rod 231 will be eliminated. The operator can push the grip handle 235 towards the position of the semi-circular locking block 21. The two connecting rods 231 will drive the movable end of the semi-circular locking block 21 to separate to both sides. The pressure of the two semi-circular locking blocks 21 on the conveying pipe 13 will disappear, so that the fixing component 2 can be easily removed from the output end of the conveying pipe 13, thereby releasing the conveying pipe 13.

[0034] In some embodiments, the remote-controlled concrete spraying equipment also includes a connecting ring 3, see [link to documentation]. Figure 1 ; The connecting ring 3 is sleeved on the conveying pipe 13, and the connecting ring 3 is arranged close to the output end of the conveying pipe 13; By operating the control end of the clamping device 23, the linkage end of the clamping device 23 is controlled to move, so as to drive the movable ends of the two semi-arc blocks 21 to move closer together, thereby clamping the connecting ring 3. This avoids the situation where the two semi-arc blocks 21 squeeze the conveying pipe 13 when clamping the output end of the conveying pipe 13, causing the conveying pipe 13 to deform and affecting the conveying efficiency of the conveying pipe 13, or causing the concrete to be unable to be output from the output end of the conveying pipe 13.

[0035] Preferably, the outer wall of the connecting ring 3 is provided with a limiting groove 31 to facilitate the insertion of the semi-arc block 21, so as to prevent the semi-arc block 21 from sliding along the axial direction of the conveying pipe 13 during the clamping process, so as to make the fixing component 2 more convenient when clamping the conveying pipe 13.

[0036] In some embodiments, the concrete pump truck 1 described above further includes a vehicle body 11 and a folding robotic arm 12, see [link to previous document]. Figure 4 and Figure 5 ;in, The vehicle body 11 is provided with a concrete storage bin 111 and a support frame 14; a delivery pump 112 is provided at the bottom of the concrete storage bin 111, the pump inlet of the delivery pump 112 is connected to the interior of the concrete storage bin 111, and the pump outlet of the delivery pump 112 is connected to the delivery pipe 13. The fixed end of the folding robotic arm 12 is hinged to the end of the vehicle body 11 away from the support frame 14. That is, the fixed end of the folding robotic arm 12 and the support frame 14 are located at opposite ends of the long axis of the loading portion in the vehicle body 11. When the folding robotic arm 12 is in the folded state, the portion of the folding robotic arm 12 away from the fixed end is mounted on the support frame 14. See [reference needed]. Figure 4 ; The conveying pipe 13 is arranged along the extension direction of the folding robotic arm 12, and the conveying pipe 13 is mounted on the folding robotic arm 12. When the vehicle body 11 is in a moving state, the aforementioned support frame 14 can fix the folded robotic arm 12 to prevent the folded robotic arm 12 from being affected by the bumps of the vehicle body 11 when the vehicle body 11 moves, thereby reducing the force on the folded robotic arm 12 and increasing the service life of the folded robotic arm 12.

[0037] In some embodiments, the support frame 14 described above includes a support body 141, a limiting body 142, and a drive assembly. See also... Figure 6 and Figure 7 ; The support body 141 is mounted on the vehicle body 11. The support body 141 is provided with a first slot 1411 for placing the folding robotic arm 12 and a second slot 1412 for placing the delivery pipe 13. The drive assembly is mounted on the support body 141. The limiting body 142 is set at the actuating end of the drive component; When the folding robotic arm 12 and the conveying pipe 13 are in the folded state, the part of the folding robotic arm 12 away from the hinge can be placed in the first bayonet 1411 and the second bayonet 1412. At this time, the operator can control the drive component to move the limiting body 142 to the upper end face of the folding robotic arm 12 and the conveying pipe 13. The limiting body 142 clamps and fixes the folding robotic arm 12 and the conveying pipe 13 in the first bayonet 1411 and the second bayonet 1412 to fix the folding robotic arm 12.

[0038] It should be noted that the aforementioned drive component is electrically connected to the control panel of the vehicle body 11. An operation button is provided on the control panel of the vehicle body 11. Pressing the operation button can start and stop the drive component.

[0039] In some embodiments, the drive assembly described above includes a rotary motor 143, see [link to previous document]. Figure 7 ;in, The rotating motor 143 is mounted on the support body 141, and the rotation axis of the rotating motor 143 is parallel to the horizontal plane; The limiting body 142 is provided with a first connecting rod 1421 and a second connecting rod 1422 at both ends. The end of the first connecting rod 1421 away from the limiting body 142 is rotatably mounted on the side wall of the supporting body 141, and the end of the second connecting rod 1422 away from the limiting body 142 is mounted on the actuating end of the rotating motor 143. In the initial state, the limiting body 142 clamps and fixes the folding robotic arm 12 and the delivery tube 13 in the first bayonet 1411 and the second bayonet 1412; When the folding robotic arm 12 needs to be used, the operator can control the rotation motor 143 to move. At this time, the rotation motor 143 drives the limiting body 142 to rotate around the axis of the rotation motor 143 through the second connecting rod 1422. The limiting body 142 will then move to the end of the folding robotic arm 12 away from the fixed end of the folding robotic arm 12. Then the operator controls the folding robotic arm 12 to unfold, so as to avoid the folding robotic arm 12 being constrained when unfolding. When the folding robotic arm 12 needs to be stored, the operator controls the folding robotic arm 12 to fold, and the part of the folding robotic arm 12 away from the fixed end is placed on the support frame 14. Then, the operator can control the rotating motor 143 to move. At this time, the rotating motor 143 drives the limiting body 142 to rotate around the axis of the rotating motor 143 through the second connecting rod 1422. The limiting body 142 will then move to the upper end face of the folding robotic arm 12 away from the fixed end to fix the folding robotic arm 12 and prevent the folding robotic arm 12 from shaking up and down due to the impact of bumps during the movement of the vehicle body 11.

[0040] Preferably, the limiting body 142 is provided with a first fixing port and a second fixing port at the positions corresponding to the first locking port 1411 and the second locking port 1412, respectively. The cooperation of the first locking port 1411 and the first fixing port, as well as the cooperation of the second locking port 1412 and the second fixing port, can better restrict the folding robotic arm 12 and the conveying pipe 13.

[0041] In some embodiments, the drive assembly described above further includes a lifting motor 144, see [link to relevant documentation]. Figure 6 ;in, The lifting motor 144 is mounted on the support body 141, and the actuating end of the lifting motor 144 is provided with a sliding block 17. The rotating motor 143 is mounted on the support body 141 through the sliding block 17. A slide groove 1413 is provided on one side of the support body 141 corresponding to the first connecting rod 1421. The extension direction of the slide groove 1413 is parallel to the action direction of the lifting motor 144. A slider 1414 is provided in the slide groove 1413 and slides along the length of the slide groove 1413. The end of the first connecting rod 1421 away from the limiting body 142 is rotatably mounted on the slider 1414. When the folding robotic arm 12 needs to be used, the operator can first control the lifting motor 144 to push the slider 1414 upward, and the slider 1414 will drive the limiting body 142 to move upward, so as to increase the distance between the limiting body 142 and the upper end face of the folding robotic arm 12 away from the fixed end of the folding robotic arm 12; then control the rotation motor 143, and drive the limiting body 142 to move around to the end of the folding robotic arm 12 away from the fixed end of the folding robotic arm 12; When the folding robotic arm 12 needs to be stored, the operator controls the folding robotic arm 12 to fold, and the part of the folding robotic arm 12 away from the fixed end is placed on the support frame 14. Then, the operator can control the rotating motor 143 to move. At this time, the rotating motor 143 will drive the limiting body 142 to rotate around the axis of the rotating motor 143 through the second connecting rod 1422. The limiting body 142 will then move to the top of the folding robotic arm 12 away from the fixed end. Then, the lifting motor 144 is controlled to pull the slider 1414 down. The slider 1414 drives the limiting body 142 to move down to fix the folding robotic arm 12.

[0042] In this embodiment, a receiving cavity is provided in the middle of the support body 141, and the sliding block 17 is slidably disposed in the receiving cavity. One end of the sliding block 17 extends through the side wall of the support body 141 to the outside. The rotating motor 143 is connected to the sliding block 17. When the sliding block 17 slides up and down, it can drive the rotating motor 143 to move together. The bottom of the receiving cavity is provided with a mounting groove, and the aforementioned lifting motor 144 is installed in the mounting groove. The actuating end of the lifting motor 144 passes through the part between the mounting groove and the receiving cavity and is connected to the sliding block 17 to drive the sliding block 17 to slide up and down in the receiving cavity.

[0043] In some embodiments, the vehicle body 11 described above is provided with a rotating mounting platform 15, and the rotation axis of the moving end of the rotating mounting platform 15 is perpendicular to the horizontal plane. The fixed end of the folding robotic arm 12 is hinged to the rotating mounting platform 15 so that the fixed end of the folding robotic arm 12 can rotate around the rotation axis of the rotating mounting platform 15, thereby increasing the range of motion of the folding robotic arm 12 and thus increasing the pouring range of the remote-controlled concrete spraying equipment.

[0044] In some embodiments, the vehicle body 11 is provided with four support legs 16, which are evenly distributed around the circumference of the vehicle body 11. In this embodiment, the vehicle body 11 is provided with outwardly extending rotating telescopic arms on both sides near the front of the vehicle, and the rotation axis of the rotating telescopic arms is perpendicular to the horizontal plane. The vehicle body 11 has rotating plates rotatably connected to both sides near the rear of the vehicle, and the rotation axis of the rotating plates is also perpendicular to the horizontal plane. Both the rotating telescopic arm and the rotating plate extend or rotate outward via hydraulic telescopic rods. Both the rotating telescopic arm and the rotating plate are equipped with electric telescopic rods at their ends, and the telescopic ends of the electric telescopic rods are detachably connected to a support base. Before using the remote-controlled concrete spraying equipment to pour concrete, the operator can control the extension of the rotating telescopic arm and rotating plate, and control the extension of the electric telescopic rod to ensure that all support bases are supported on the ground, thereby increasing the stability of the vehicle body 11. This makes the vehicle body 11 more stable when the remote-controlled concrete spraying equipment is pouring concrete, thus improving the safety of the equipment during use.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
