Description

Technical Field

[0001] The invention relates to the field of fan foundation construction, and in particular to a concrete feeding device for a fan foundation construction project. Background Art

[0002] Wind turbine foundation construction is a key link in wind power generation projects. Its quality and stability directly affect the operating efficiency and safety of wind turbines. During the construction process, it is generally necessary to conduct on-site surveys, excavate the foundation, build the foundation formwork, build and bundle the steel bars, and finally pour concrete to form the foundation, thereby laying a good foundation for the subsequent construction of the wind turbine body.

[0003] The patent application with announcement number CN220181884U, a concrete conveying device, includes a base plate, a conveying mechanism with a spiral conveying rod is arranged on the top of the base plate, a crushing mechanism is arranged at the input end of the conveying mechanism, and the conveying mechanism is connected with the crushing mechanism, a buffer mechanism with a viscoelastic damper is arranged between the base plate and the conveying mechanism, a drainage mechanism is arranged at the bottom end of the conveying mechanism, the conveying mechanism includes a spiral conveying rod, a feeding barrel is arranged on the top of the base plate, and a multi-stage electric push rod is fixedly installed on the top of the base plate. The utility model provides a concrete conveying device, which can scrape the concrete adhering to the inner wall of the feeding barrel by a scraper to avoid excessive concrete adhesion affecting the conveying efficiency of the next concrete, and at the same time, some large stones contained in the concrete can be crushed by a crushing roller to avoid the stones from hitting and damaging the spiral conveying rod, thereby affecting the concrete conveying.

[0004] In the existing construction process, since the body of the wind turbine is relatively large, and the traditional foundation construction needs to calculate the embedded depth and volume of the foundation according to the height of the structure, the existing wind turbine foundation volume and embedded depth are generally large. At this time, when concrete pouring is required after the construction is completed, the pouring arm in front of the traditional concrete pouring vehicle needs to be manually controlled in direction. However, due to the large depth and area of ​​the foundation pit, it is impossible to enter the foundation pit during pouring, otherwise there is a risk of people falling. Therefore, concrete pouring is generally carried out along the periphery of the foundation pit. However, this pouring method will result in uneven concrete pouring and inconsistent pouring speed when pouring in such a large foundation pit. This method will cause the concrete to be layered, thereby affecting the normal pouring of the foundation and the strength of the foundation pouring.

[0005] Therefore, it is necessary to invent a concrete feeding device for a fan foundation construction project to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0035] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0036] The present invention provides Figure 1-10 A concrete feeding device for a wind turbine foundation construction project shown in the figure comprises a base 001, four sets of auxiliary support frames 101 are installed around the base 001, a damping shaft 102 is installed at the center position above the base 001, and a bearing frame 103 is installed above the damping shaft 102;

[0037] The supporting frame 103 can be manually rotated above the base 001 by means of the damping shaft 102 , and when the manual rotation is stopped, the position of the supporting frame 103 is fixed and will not rotate on its own.

[0038] The conveying assembly 002 disposed in the carrying frame 103 includes a carrying frame 1 201, one side of the carrying frame 201 is rotatably connected to the carrying frame 103, and the side of the carrying frame 201 away from the carrying frame 103 is penetrated and slidably connected to a carrying frame 2 205;

[0039] The second carrier frame 205 slides inside the first carrier frame 201, thereby achieving the effect of adjusting the concrete conveying distance.

[0040] The spacing adjustment assembly 003 disposed in the first carrier 201 includes a screw rod 311, which is rotatably connected to the inside of the first carrier 201, and one side of the screw rod 311 is screwed to the inside of the second carrier 205;

[0041] The screw rod 1 311 rotates inside one side of the support frame 205 , so that the support frame 205 moves inside the support frame 1 201 , thereby driving the support frame 205 .

[0042] The retractable and retractable adjustment component 004 disposed in the carrying frame 103 includes a through slot 1 401, which is symmetrically arranged on the inner wall of the carrying frame 103, and two sets of through slots 1 401 are slidably connected with connecting seats 404, and the connecting seats 404 are rotatably connected with a limiting roller 1 405, and a side of the inner wall of the carrying frame 103 away from the limiting roller 1 405 is rotatably connected with a limiting roller 2 406;

[0043] The connecting seat 404 slides in the through slot 1 401 , thereby driving the limiting roller 1 405 to move in the carrying frame 103 .

[0044] The height adjustment component 005 arranged in the supporting frame 103 includes a through slot 2 501, which is symmetrically opened on the inner wall of the supporting frame 103 and is located above the through slot 1 401. The two groups of through slots 2 501 are slidably connected with sliding seats 502, and the two groups of sliding seats 502 are rotatably connected with a limiting roller 3 507.

[0045] The sliding seat 502 slides in the second through groove 501 , so that the limiting roller three 507 can be mobilized to move in the carrying frame 103 .

[0046] Furthermore, in the above structure, the conveying assembly 002 also includes a conveying roller 202, which is rotatably connected to the side of the support frame 201 away from the support frame 205, and the side of the support frame 205 away from the support frame 201 is rotatably connected to the conveying roller 206, and a conveyor belt 207 is fittedly connected between the conveying roller 1 202, the conveying roller 206, the limiting roller 1 405, the limiting roller 2 406 and the limiting roller 3 507.

[0047] Through the rotation of the conveying roller 1 202, the conveying belt 207 can move between the conveying roller 2 206, the limiting roller 1 405, the limiting roller 2 406 and the limiting roller 3 507, thereby realizing the conveying of concrete.

[0048] Furthermore, in the above structure, a servo motor 203 is installed on one side of the carrier frame 201, and the servo motor 203 is axially connected to the conveying roller 202. Baffles 204 are symmetrically installed on the carrier frame 201 and the carrier frame 205, and the length of the baffle 204 on the carrier frame 201 is greater than that on the carrier frame 205, and the two groups of baffles 204 are arranged in a staggered and overlapping manner, and the baffles 204 are located on the edges of both sides of the conveyor belt 207.

[0049] The servo motor 203 can drive the conveying roller 202 to rotate, and the baffle 204 can ensure that the concrete will not fall off the edges of both sides of the conveyor belt 207, and the two sets of baffles 204 can still cooperate when the support frame 205 moves in the support frame 201, thereby continuing the protective effect.

[0050] Furthermore, in the above structure, a discharge hopper 208 is rotatably connected below the support frame 205, a scraper 209 is installed inside the discharge hopper 208, and the scraper 209 is in contact with the surface of the conveyor belt 207, and a counterweight block 210 is installed at the bottom of the discharge hopper 208 away from the scraper 209.

[0051] The counterweight block 210 can make the discharge hopper 208 under the supporting frame 205 in a state where one side is heavier, so that the scraper 209 is always in contact with the surface of the conveyor belt 207, so that excess concrete can be scraped into the discharge hopper 208 and slide into the foundation pit along with the inside of the discharge hopper 208.

[0052] Furthermore, in the above structure, the spacing adjustment component 003 also includes a bevel gear 301, which is rotatably connected to the inside of the carrier frame 201, and the bevel gear 301 is axially connected to the conveying roller 202. The inside of the carrier frame 201 is rotatably connected with a connecting shaft 302, and one side of the connecting shaft 302 is connected to a bevel gear 2 303, and the bevel gear 2 303 is meshed with the bevel gear 1 301.

[0053] The conveying roller 1 202 can drive the bevel gear 1 301 to rotate, so that the bevel gear 1 301 cooperates with the bevel gear 2 303 to drive the connecting shaft 302 to rotate.

[0054] Furthermore, in the above structure, a docking hole 304 is provided on the side of the connecting shaft 302 away from the bevel gear 2 303, and a limiting groove 305 is symmetrically provided on the inner wall of the docking hole 304. A sleeve 306 is sleeved on the connecting shaft 302, and a docking rod 307 is installed on the inner wall of the sleeve 306, and the docking rod 307 is connected through the docking hole 304, and a limiting block 308 is symmetrically installed on the docking rod 307, and the limiting block 308 is slidably connected to the limiting groove 305.

[0055] Through the cooperation of the limiting groove 305 and the limiting block 308 , the connecting shaft 302 can drive the sleeve 306 to rotate simultaneously when rotating, and the sleeve 306 can move back and forth laterally along the connecting shaft 302 without affecting its rotation.

[0056] Furthermore, in the above structure, a retaining ring 313 is sleeved and fixed on the connecting shaft 302, a spring 309 is sleeved on the connecting shaft 302, and both sides of the spring 309 are respectively fitted with the inner wall of the sleeve 306 and the retaining ring 313, a plurality of groups of arc strips 310 are installed in a circular distribution on the outer side of the sleeve 306, a plurality of groups of arc strips 312 are installed in a circular distribution on the end of the screw 1 311 away from the supporting frame 2 205, and the arc strips 1 310 and the arc strips 2 312 are cross-fitted.

[0057] The spring 309 can make the arc strip 1 310 and the arc strip 2 312 on one side of the sleeve 306 always in a fit state, but because the screw rod 1 311 is in a locked state after being in place with the internal thread of the supporting frame 205, the screw rod 1 311 cannot rotate at this time, and because the arc surfaces of the arc strip 1 310 and the arc strip 2 312 are symmetrical with each other, slipping occurs, so that the sleeve 306 is squeezed by the arc strip 1 310 and the arc strip 2 312 when rotating, so that it slides to one side along the connecting shaft 302 and squeezes the spring 309, but when the servo motor 1 203 rotates in the opposite direction, the concrete is stopped at this time, so that the arc strip 1 310 and the arc strip 2 312 are stuck to each other, and because the screw rod 1 311 is in an active state, it can drive the supporting frame 205 to move, thereby realizing the adjustment of the conveying distance.

[0058] Furthermore, in the above structure, the retractable and extendable adjustment component 004 also includes a second screw 402, which is rotatably connected to the outside of the supporting frame 103, and a second servo motor 403 is installed on the outside of the supporting frame 103, and the output end of the second servo motor 403 is connected to the second screw 402, and the second screw 402 is threadedly connected to one side of the connecting seat 404.

[0059] The screw rod 402 can be driven to rotate by the servo motor 403, so that the screw rod 402 drives the connecting seat 404 to move, so that the limiting roller 405 moves closer to the limiting roller 406, thereby loosening the conveyor belt 207. This process works in conjunction with the movement of the supporting frame 205, so as to avoid the conveyor belt 207 from breaking when the supporting frame 205 is adjusted.

[0060] Furthermore, in the above structure, the height adjustment component 005 also includes an electric telescopic rod 503, which is installed on the outside of the supporting frame 103, and the output end of the electric telescopic rod 503 is fixedly connected to the sliding seat 502. The side of the sliding seat 502 away from the electric telescopic rod 503 is rotatably connected to a push rod 504, and the push rod 504 is arranged inside the supporting frame 103. A slide groove 505 is opened on the side of the push rod 504 away from the sliding seat 502, and a fixed shaft 506 is connected to the inner wall of the slide groove 505, and the fixed shaft 506 is fixedly connected to the outer side of the supporting frame 201.

[0061] The sliding seat 502 is driven to move by the electric telescopic rod 503. At this time, the sliding seat 502 can mobilize the slide groove 505 on one side of the push rod 504 to slide along the fixed shaft 506, and with the continuous movement, it presses against the fixed shaft 506, and finally lifts up one side of the carrier frame 201 as a whole, so that the conveying angle of the conveyor belt 207 is changed, and in this process, the sliding seat 502 drives the limiting roller three 507 to move, so as to relax the conveyor belt 207, and present a synchronous cooperation state, and does not need the cooperation of the limiting roller one 405 at the bottom.

[0062] like Figure 1-10 As shown, by setting up the device as a whole to the edge of the foundation pit, and rotating the servo motor 203 in the opposite direction, the bevel gear 301 drives the bevel gear 303 to rotate, so that the connecting shaft 302 drives the screw 311 to rotate and push the support frame 205 to slide in the support frame 201, and at the same time, the servo motor 403 below cooperates synchronously to make the limiting roller 405 move closer to the limiting roller 406, so that the distance between the conveying roller 202 and the conveying roller 206 is lengthened, thereby increasing the conveying distance of the concrete, and the sliding seat 502 is driven to move by the electric telescopic rod 503, so that the push rod 504 pushes the side of the support frame 201 to move, so that one side of the support frame 201 is tilted, so that the support frame 1 The overall angle of 201 changes, and at the same time, the limiting roller three 507 is driven to move, and the conveyor belt 207 is further relaxed. When the adjustment is completed, the servo motor 203 rotates forward and places the concrete on the conveyor belt 207, so that the conveyor belt 207 drives the concrete to move into the discharge hopper 208 and finally falls into the foundation pit. The discharge hopper 208 is added with the gravity of the concrete, so that the scraper 209 can further scrape off the residual concrete on the conveyor belt 207, and the bearing frame 103 is manually rotated to achieve precise pouring of concrete. In this way, the effect of uniform pouring of such a large foundation pit can be achieved, thereby ensuring the strength of the foundation and reducing the risk to personnel, and this structure is also convenient for the later cleaning of the inside of the device.

[0063] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
