Technical Field

[0001] This utility model relates to the field of hoisting and pouring technology, and in particular to a hoisting and pouring device for concrete pouring. Background Technology

[0002] The concrete pouring hoisting device is a construction equipment that integrates hoisting and precision pouring functions. It mainly consists of a hopper, discharge pipe, sealing mechanism, plate assembly and hoisting interface. Its core function is to transfer concrete from the mixing plant or transport vehicle to the pouring position at high altitude or complex terrain through the hoisting system, and to control the flow rate and landing point of the concrete through the discharge pipe. It is widely used in high-rise buildings, bridges and tunnel projects.

[0003] In current technology, concrete residue will remain on the inner wall of the transfer bucket. If not cleaned in time, it will harden and become difficult to remove. The cleaning process can damage the equipment, and the long-term accumulation will reduce the capacity of the transfer bucket. The existing technology is to install fixed scrapers on the inner wall of the transfer bucket to remove the adhering concrete by physical scraping, which can reduce the residue rate and reduce equipment damage. However, the scraper will be damaged by long-term friction with the concrete and needs to be replaced regularly. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a hoisting and pouring device for concrete pouring, which aims to improve the problem in the prior art where the scraper is damaged due to long-term friction with the concrete and needs to be replaced regularly.

When the hydraulic push rod is activated, it drives the transmission rod to move up and down. During the movement, the support rod and scraper move simultaneously. The scraper can scrape the residual concrete on the inner wall of the machine into the funnel-shaped area during the movement. After the concrete gradually accumulates, it flows out through the discharge pipe. The hydraulic push rod is fixed to the machine body by the support plate, fixing ring and bolts.

At this time, the hydraulic push rod 2041 is activated, driving the transmission rod 201 to move up and down. When the transmission rod 201 moves, it simultaneously drives the support rod 202 and the scraper 203 to move. During the movement, the scraper 203 can scrape the residual concrete on the inner wall of the machine body 1 into the funnel-shaped area of ​​the machine body 1, and finally flow out through the discharge pipe 6. The hydraulic push rod 2041 is fixed to the machine body 1 by the support plate 2044, the fixing ring 2043 and the bolt 2042. The bolt 2042 can fasten the hydraulic push rod 2041 in the upper position to prevent it from falling or shifting.

[0018] Reference Figure 2 , Figure 3 and Figure 5 The closing mechanism 3 includes a baffle 301, which is installed at the middle of the end of the machine body 1. A fixed rod 302 is fixedly connected to the middle of the left end of the baffle 301, and a handle 303 is fixedly connected to the left end of the fixed rod 302. A shaft pin 304 is rotatably connected to the upper and lower sides and the front and rear ends of the baffle 301. A pin shaft 305 is rotatably connected to the end of the shaft pin 304. A support ring 306 is slidably connected to the bottom of the baffle 301. A guide rod 307 is fixedly connected to the front and rear sides of the bottom of the baffle 301. The guide rod 307 is slidably connected to the support ring 306. The baffle 301 is slidably connected to the discharge pipe 6. The support frame 4 is slidably connected to the baffle 301. The shaft pin 304 is slidably connected to the support frame 4. The support frame 4 is fixedly connected to the support ring 306. Specifically, the machine body 1 is lifted to the pouring position by hooking the lifting ring 5 with a crane. First, the pin 305 is manually pulled out, and then the shaft pin 304 is pulled out to disconnect the baffle 301 from the support frame 4. The shaft pin 304 is used to fix the baffle 301 above the support frame 4 and below the discharge pipe 6 to prevent concrete leakage during the movement of the machine body 1. Then, the worker holds the handle 303 and pulls it to the left, and the baffle 301 is pulled away from the bottom of the discharge pipe 6 through the fixing rod 302. The concrete flows out naturally along the machine body 1. During the pulling of the baffle 301, its guide rod 307 moves synchronously. In the reciprocating movement, the guide rod 307 plays a guiding role to prevent the baffle 301 from deviating from the discharge pipe 6. After the concrete is poured out, the position of the baffle 301 is reset, and the shaft pin 304 is inserted back to complete the unloading and equipment restoration operation. The support ring 306 is used to connect the four support frames 4 to improve the overall stability of the equipment.

[0019] Reference Figure 1 Support frames 4 are fixedly connected to the outer perimeter of the machine body 1, lifting rings 5 ​​are fixedly connected to the top perimeter of the machine body 1, and discharge pipes 6 are fixedly connected to the bottom of the machine body 1. Specifically, there is a support frame 4 on the outside of the machine body 1, and a lifting ring 5 is installed on the top of the machine body 1. The lifting work can be carried out by hooking the lifting ring 5 with a crane. There is a discharge pipe 6 at the bottom of the machine body 1.

[0020] Working principle: After all the concrete in the machine body 1 has flowed out, due to the high viscosity of the concrete, some concrete will stick to the inner wall of the machine body 1. At this time, the hydraulic push rod 2041 is activated, which will move the transmission rod 201 up and down. When the transmission rod 201 moves, it will move the support rod 202 and the scraper 203 at the same time. When the scraper 203 moves, it can scrape the concrete in the machine body 1 onto the funnel-shaped machine body 1, where it accumulates and then flows out through the discharge pipe 6. The hydraulic push rod 2041 is fixed to the machine body 1 using the support plate 2044, the fixing ring 2043 and the bolt 2042. The bolt 2042 can fasten the hydraulic push rod 2041 to the top to prevent it from falling or shifting. Using a crane, hook the lifting ring 5 to lift the machine body 1 to the location where concrete needs to be poured. First, manually pull out the pin 305, then pull out the shaft pin 304, so that the baffle 301 is disconnected from the support frame 4. The shaft pin 304 can fix the baffle 301 above the support frame 4 and below the discharge pipe 6 to prevent concrete from leaking out during the movement of the machine body 1. Then, the worker holds the handle 303 and pulls to the left, pulling the baffle 301 away from below the discharge pipe 6 through the fixing rod 302. The concrete flows out naturally along the machine body 1. During the pulling process, the guide rod 307 of the baffle 301 moves synchronously. During the back and forth movement, the guide rod 307 plays a guiding role to prevent the baffle 301 from deviating from the discharge pipe 6. After the concrete is poured out, restore the position of the baffle 301, and then insert the shaft pin 304 to complete the unloading and restoration of the equipment. The support ring 306 is used to connect the four support frames 4 to improve the overall stability of the equipment.
