Description

Technical Field

[0001] The present invention relates to the technical field of concrete foundation pouring construction, and in particular to an intelligent remote-controlled concrete tower crane hopper. Background Art

[0002] In the construction industry, concrete pouring, especially for capacitor bank foundations and other concrete foundation construction, often requires the use of a concrete tower crane hopper in conjunction with a crane. The current common construction method involves workers standing beneath the crane boom and manually controlling the opening and closing of the tower crane hopper valve to control the concrete flow rate and complete the foundation pouring operation.

[0003] However, this construction situation presents significant drawbacks. Workers standing beneath the crane boom seriously violate the safety regulations prohibiting standing beneath the boom, posing a significant safety hazard. Furthermore, the manual control valve operation mode prevents remote control, limiting operational flexibility and, to a certain extent, hindering on-site efficiency.

[0004] Currently, most common concrete tower crane buckets on the market utilize close-range manual operation. While this approach offers ease of operation, conflicts with safety regulations and limitations in efficiency remain unresolved. Therefore, developing a new concrete tower crane bucket that meets construction requirements while ensuring operator safety and improving efficiency has become a pressing technical challenge in this field.

[0017] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0018] The present invention provides an intelligent remote-controlled concrete tower crane hopper, which Figure 1 (tower crane hopper body) and Figure 5(Intelligent remote control device) consists of two parts, specifically including the following: tower crane hopper body 1; tower crane hopper bracket 2; tower crane hopper lifting ring 3; tower crane hopper valve 4; double-layer transmission gear 5; transmission gear 6; limit rack 7; valve transmission chain 8; intelligent remote control device backpack 9; DC reduction motor 10; DC motor forward and reverse remote control switch 11; DC motor forward and reverse remote control 12; travel limiter 13; travel baffle 14; lithium-ion rechargeable battery 15; maintenance side door 16; DC reduction motor tray 17; DC motor forward and reverse remote control switch hook 18; lithium-ion rechargeable battery slot 19; intelligent remote control device backpack side door lock 20; gear support rod 21; coaxial three-layer transmission gear 22; motor gear support rod 23; coaxial double-layer motor gear 24; motor transmission chain 25.

[0019] The tower crane hopper body 1 is welded to the tower crane hopper bracket 2 and the tower crane hopper lifting ring 3. A double-layer transmission gear 5 and transmission gear 6 are welded on both sides of the tower crane hopper valve 4. The two are meshed and fixed to the material outlet of the tower crane hopper body 1, allowing for flexible rotation. The intelligent remote control device backpack 9 is a container device welded to the side of the tower crane hopper body 1. A maintenance side door 16 that can be opened or locked is designed on one side of the intelligent remote control device backpack 9. A DC reduction motor tray 17, a DC motor forward and reverse remote control switch hook 18, a lithium-ion rechargeable battery tray 19, and a motor gear support rod 23 are welded to one side of the inner wall of the intelligent remote control device backpack 9. The DC reduction motor 10 is fastened to the DC reduction motor tray 17 by bolts. The DC motor forward and reverse remote control switch 11 is suspended from the DC motor forward and reverse remote control switch hook 18. The lithium-ion rechargeable battery 13 is placed in the lithium-ion rechargeable battery slot 19. The coaxial double-layer motor gear 24 inside the smart remote control backpack 9 is mounted on a motor gear support rod 23 and can be rotated by a motor. The limit rack 7 is fixed by inlay in a dedicated track groove on the inner side of the outer wall of the smart remote control backpack 9 and can slide freely. A raised travel stop 14 is welded to the head of the limit rack 7. Two travel limiters 13 are installed on the upper and lower sides of the same vertical direction as the travel stop 14. The side door of the smart remote control backpack 9 can be locked by the smart remote control backpack side door lock 20.

[0020] Working principle: When the tower crane hopper valve 4 is closed, it is the initial working state ( Figure 2), which can now hold a certain amount of concrete. When pouring begins, the construction worker can signal the start of the pouring operation by pressing the forward button on the DC motor forward / reverse remote control 12. The DC motor forward / reverse remote control 11 within the intelligent remote control backpack 9 receives the forward rotation signal for the DC reduction motor 10 and transmits it to the DC reduction motor 10, causing it to begin forward rotation. During this process, the DC reduction motor 10 drives the coaxial double-layer motor gear 24 within the intelligent remote control backpack 9 to rotate synchronously. This, in turn, also drives the coaxial three-layer transmission gear 22 via the motor transmission chain 25, simultaneously causing the limit rack 7, which meshes with the coaxial double-layer motor gear 24, to move upward. Simultaneously, the coaxial three-layer transmission gear 22 drives the double-layer transmission gear 5 via the valve transmission chain 8, causing it to begin rotating. Finally, the meshing relationship between the double-layer transmission gear 5 and the transmission gear 6 opens the tower crane hopper valves 4 on both sides. During the process of the tower crane hopper valve 4 continuously opening to both sides, the uppermost travel baffle 14 of the limit rack 7 touches the travel limiter 13 installed on the upper part of the intelligent remote control device backpack 9. At this time, the DC motor forward and reverse remote control switch 11 receives the maximum forward travel signal and stops the DC reduction motor 10 from rotating forward. The tower crane hopper valve 4 reaches the maximum opening and closing degree ( Figure 3 After the concrete pouring is completed, the construction worker can press the reverse button on the DC motor forward / reverse remote control 12. At this time, the DC motor forward / reverse remote control switch 11 in the intelligent remote control device backpack 9 receives the signal to reverse the DC reduction motor 10 and transmits it to the DC reduction motor 10, causing it to begin reverse rotation. During this process, the DC reduction motor 10 drives the coaxial double-layer motor gear 24 in the intelligent remote control device backpack 9 to synchronously reverse, and drives the coaxial three-layer transmission gear 22 through the motor transmission chain 25 to also begin reverse rotation. At the same time, the transmission rack 7, which is meshed with the coaxial double-layer motor gear 24, moves downward. At the same time, the coaxial three-layer transmission gear 22 drives the double-layer transmission gear 5 through the valve transmission chain 8 to begin rotating and reverse rotation. Finally, the meshing relationship between the double-layer transmission gear 5 and the transmission gear 6 slowly closes the tower crane hopper valves 4 on both sides. During the continuous closing process of the tower crane hopper valve 4, the uppermost travel baffle 14 of the transmission rack 7 touches the travel limiter 13 installed at the bottom of the intelligent remote control device backpack 9. At this time, the DC motor forward and reverse remote control switch 11 receives the maximum reverse travel signal and stops the DC reduction motor 10 from reversing. The tower crane hopper valve 4 reaches the initial closed state ( Figure 1 During the entire operation, the power supply for the DC motor forward and reverse remote control switch 11 is provided by the lithium-ion rechargeable battery 15.

[0021] Working process: Before the concrete pouring operation begins, the tower crane hopper valve 4 is closed ( Figure 2), the tower crane hopper body 1 can be stably placed on the ground with the help of the tower crane hopper bracket 2. At this time, the concrete material can be transported to the tower crane hopper body 1 by a concrete tank truck. After the concrete material is received, the tower crane hopper body 1 is lifted by a crane through the tower crane hopper lifting ring 3, and moved to hover just above the construction area where concrete needs to be poured. The construction worker can hold the DC motor forward and reverse remote control 12 and stand in a safe area at a certain distance below the crane arm, and remotely press the forward button on the DC motor forward and reverse remote control 12. At this time, the coaxial double-layer motor gear 24 in the intelligent remote control device backpack 9 will be driven by the forward rotation of the DC reduction motor 10, through the valve transmission chain 8 and the motor transmission chain 25, to drive the coaxial three-layer transmission gear 22 and the double-layer transmission gear 5 and the transmission gear 6 to rotate forward respectively, thereby causing the tower crane hopper valve 4 to gradually open to both sides to allow the concrete material to flow down smoothly ( Figure 3 ), wherein the opening and closing degree of the tower crane hopper valve 4 can be controlled by the DC motor forward and reverse remote control 12 to achieve the purpose of controlling the flow rate of the concrete material. When the concrete pouring operation is completed, the construction worker can press the reverse button on the DC motor forward and reverse remote control 12. At this time, the coaxial double-layer motor gear 24 in the intelligent remote control device backpack 9 will be driven by the reverse action of the DC reduction motor 10, through the valve transmission chain 8 and the motor transmission chain 25, to drive the coaxial three-layer transmission gear 22 and the double-layer transmission gear 5 and transmission gear 6 to rotate in the opposite direction, thereby causing the tower crane hopper valve 4 to slowly close from both sides toward the center, completing the concrete pouring operation. After the pouring work is completed, the tower crane hopper is placed on the ground by a crane, and the entire concrete pouring operation process is completed.
