Description

TECHNICAL FIELD

[0002] Fan foundation construction is a key link in a wind power generation project, and the quality and stability thereof directly affect the operation efficiency and safety of a wind turbine, in the construction process, generally, after site survey, the foundation is formed through excavation of a foundation, erection of a foundation template, erection and binding of steel bars, and finally molding through concrete pouring.

The concrete feeding device can scrape the inner wall of the feeding barrel to avoid excessive adhesion of concrete, which affects the efficiency of the next concrete feeding. Meanwhile, the crushing roller can crush large stones in the concrete to avoid damage to the spiral feeding rod caused by the impact of the stones, thereby affecting the concrete feeding.

[0004] In the existing construction process, the body of the wind turbine is large, and the traditional foundation construction needs to measure the embedded depth and volume of the foundation according to the height of the erected object. Therefore, the volume and embedded depth of the existing wind turbine foundation are generally large. When the concrete pouring is performed after the erection, 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, the concrete pouring cannot be performed inside the foundation pit, otherwise the risk of falling of personnel may occur. Therefore, the concrete pouring is generally performed along the periphery of the foundation pit. However, this pouring method may cause uneven concrete pouring and non-uniform pouring speed when the large foundation pit is poured.

DETAILED DESCRIPTION

[0035] In order to make the technical personnel in the art better understand the technical solutions of the present application, the present application will be further described in detail below with reference to the drawings.

[0037] The damping rotating shaft 102 can manually rotate the bearing frame 103 above the base 001, and when the manual rotation is stopped, the position of the bearing frame 103 is fixed and no self-rotation occurs.

[0038] The conveying assembly 002 arranged in the bearing frame 103 includes a bearing frame one 201 rotatably connected to the bearing frame 103 on one side, and a bearing frame two 205 slidably connected to the bearing frame one 201 on the side away from the bearing frame 103.

[0039] The bearing frame two 205 slides in the bearing frame one 201, thereby achieving the effect of adjusting the conveying distance of the concrete.

[0040] The spacing adjustment assembly 003 arranged in the bearing frame one 201 includes a screw one 311 rotatably connected in the bearing frame one 201, and the screw one 311 is screwed with the bearing frame two 205 on one side.

[0041] The screw rod 311 rotates inside the side of the bearing frame 205, thereby moving the bearing frame 205 inside the bearing frame 201, so as to drive the bearing frame 205.

[0042] The folding adjusting assembly 004 arranged in the bearing frame 103 comprises a through groove 401, which is symmetrically arranged on the inner wall of the bearing frame 103, and two groups of the through groove 401 are slidably connected with a connecting seat 404, the connecting seat 404 is rotatably connected with a limiting roller 405 between the two groups of the connecting seat 404, and a limiting roller 406 is rotatably connected with the inner wall of the bearing frame 103 away from the limiting roller 405.

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

[0044] The height adjusting assembly 005 arranged in the bearing frame 103 comprises a through groove 501, which is symmetrically arranged on the inner wall of the bearing frame 103, and the through groove 501 is located above the through groove 401, two groups of the through groove 501 are slidably connected with a sliding seat 502, and the limiting roller 507 is rotatably connected between the two groups of the sliding seat 502.

[0045] The sliding seat 502 slides in the through groove 501, thereby driving the limiting roller 507 to move in the bearing frame 103.

[0046] Further, in the above structure, the conveying assembly 002 further comprises a conveying roller 202, which is rotatably connected to the side of the bearing frame 201 away from the bearing frame 205, the side of the bearing frame 205 away from the bearing frame 201 is rotatably connected with a conveying roller 206, and the conveying roller 202, the conveying roller 206, the limiting roller 405, the limiting roller 406 and the limiting roller 507 are abuttingly connected with a conveying belt 207.

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

[0048] Further, in the above structure, the side of the bearing frame 201 is provided with a servo motor 203, the servo motor 203 is connected with the conveying roller 202, the bearing frame 201 and the bearing frame 205 are symmetrically provided with baffles 204, the length of the baffle 204 on the bearing frame 201 is greater than that of the baffle 204 on the bearing frame 205, the two groups of baffles 204 are staggered and overlapped, and the baffles 204 are located on both sides of the conveying belt 207.

[0049] The servo motor 203 can drive the conveying roller 202 to rotate, and the baffles 204 can prevent the concrete from falling off the edges of the conveying belt 207, and the two sets of baffles 204 can still cooperate when the carrier frame two 205 moves in the carrier frame one 201, thereby continuing the protection effect.

[0050] Further, in the above structure, the discharge hopper 208 is rotatably connected below the carrier frame two 205, the scraper 209 is installed inside the discharge hopper 208, the scraper 209 is attached to the surface of the conveying belt 207, and the counterweight 210 is installed at the bottom of the side of the discharge hopper 208 away from the scraper 209.

[0051] The counterweight 210 can make the discharge hopper 208 heavier on one side below the carrier frame two 205, so that the scraper 209 is always attached to the surface of the conveying belt 207, so that the excess concrete can be scraped into the discharge hopper 208 and then fall into the foundation pit.

[0052] Further, in the above structure, the spacing adjustment assembly 003 further comprises a bevel gear one 301 rotatably connected inside the carrier frame one 201, the bevel gear one 301 is connected with the conveying roller one 202, the carrier frame one 201 is rotatably connected with a connecting shaft 302, one side of the connecting shaft 302 is connected with a bevel gear two 303, and the bevel gear two 303 is engaged with the bevel gear one 301.

[0053] The conveying roller one 202 can drive the bevel gear one 301 to rotate, so that the bevel gear one 301 drives the connecting shaft 302 to rotate in cooperation with the bevel gear two 303.

[0054] Further, in the above structure, the connecting shaft 302 is provided with a butt joint hole 304 on the side away from the bevel gear two 303, a limiting groove 305 is symmetrically formed on the inner wall of the butt joint hole 304, a sleeve 306 is sleeved on the connecting shaft 302, a butt joint rod 307 is installed on the inner wall of the sleeve 306, and the butt joint rod 307 is connected with the butt joint hole 304, a limiting block 308 is symmetrically installed on the butt joint rod 307, and the limiting block 308 is connected with 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 at the same time when rotating, and the sleeve 306 can move vertically along the connecting shaft 302 without affecting the rotation.

[0056] Further, in the above structure, the connecting shaft 302 is sleeved and fixed with a blocking ring 313, the connecting shaft 302 is sleeved with a spring 309, and the spring 309 is attached to the inner wall of the sleeve 306 and the blocking ring 313 on both sides, a plurality of groups of arc-shaped strips one 310 are annularly distributed and installed on the outer side of the sleeve 306, a plurality of groups of arc-shaped strips two 312 are annularly distributed and installed on the end of the screw one 311 away from the bearing frame two 205, and the arc-shaped strips one 310 and the arc-shaped strips two 312 are cross attached.

[0057] The spring 309 can keep the arc-shaped strips one 310 and the arc-shaped strips two 312 on one side of the sleeve 306 in the attached state at all times, but due to the locking state of the screw one 311 after being screwed into the bearing frame two 205, the screw one 311 cannot rotate at this time, and due to the mutual symmetry of the arc-shaped surfaces of the arc-shaped strips one 310 and the arc-shaped strips two 312, a skidding condition occurs, so that the sleeve 306 is squeezed by the arc-shaped strips one 310 and the arc-shaped strips two 312 when rotating, thereby sliding to one side along the connecting shaft 302 and squeezing the spring 309, but when the servo motor one 203 reverses rotation, the concrete is in a state of stopping conveying at this time, so that the corner surfaces of the arc-shaped strips one 310 and the arc-shaped strips two 312 are mutually clamped, and due to the active state of the screw one 311, the bearing frame two 205 can be driven to move, thereby achieving adjustment of the conveying distance.

[0058] Further, in the above structure, the receiving and adjusting assembly 004 further comprises a screw two 402, the screw two 402 is rotatably connected to the outside of the bearing frame 103, a servo motor two 403 is installed on the outside of the bearing frame 103, and the output end of the servo motor two 403 is connected with the screw two 402, and the screw two 402 is screwed with one side of the connecting seat 404.

[0059] The servo motor two 403 can mobilize the screw two 402 to rotate, so that the screw two 402 drives the connecting seat 404 to move, so that the limiting roller one 405 approaches the limiting roller two 406, thereby relaxing the conveying belt 207, and this process works in cooperation with the movement of the bearing frame two 205, thereby avoiding the breaking of the conveying belt 207 when the bearing frame two 205 is adjusted.

[0060] Further, in the above structure, the height adjusting assembly 005 further comprises an electric telescopic rod 503, the electric telescopic rod 503 is installed on the outside of the bearing frame 103, the output end of the electric telescopic rod 503 is fixedly connected with the sliding seat 502, a push rod 504 is rotatably connected to the side of the sliding seat 502 away from the electric telescopic rod 503, and the push rod 504 is arranged in the bearing frame 103, a sliding groove 505 is formed in the side of the push rod 504 away from the sliding seat 502, a fixed shaft 506 is penetratingly connected to the inner wall of the sliding groove 505, and the fixed shaft 506 is fixedly connected with the outside of the bearing frame one 201.

[0061] The sliding seat 502 is moved by the electric telescopic rod 503. At this time, the sliding seat 502 can move the slide groove 505 on one side of the push rod 504 to slide along the fixed shaft 506. As it moves continuously, it abuts against the fixed shaft 506 and eventually lifts one side of the support frame 201, thereby changing the conveying angle of the conveyor belt 207. During this process, the sliding seat 502 drives the limiting roller 3 507 to move, thereby relaxing the conveyor belt 207 and presenting a synchronous cooperation state, without the need for the bottom limiting roller 405 to cooperate.

[0062] like Figures 1-10 As shown, by mounting the entire device on the edge of the foundation pit, and by rotating the servo motor 203 in the reverse direction, the bevel gear 301 drives the bevel gear 303 to rotate, causing the connecting shaft 302 to drive the screw 311 to rotate and push the support frame 205 to slide within the support frame 201. Simultaneously, the servo motor 403 below works in sync, causing the limiting roller 405 to move closer to the limiting roller 406, thus increasing the distance between the conveying rollers 202 and 206, thereby increasing the concrete conveying distance. Furthermore, the electric telescopic rod 503 drives the sliding seat 502 to move, causing the push rod 504 to push the support frame 201 to move to the side, thus causing one side of the support frame 201 to tilt up, thereby making the support frame 201... The overall angle of 201 changes, simultaneously moving the limiting roller 507 and further loosening the conveyor belt 207. After adjustment, the servo motor 203 rotates forward and places concrete onto the conveyor belt 207, causing the conveyor belt 207 to move the concrete into the discharge hopper 208 and finally into the foundation pit. As the concrete is added to the discharge hopper 208 by gravity, the scraper 209 can further scrape away the residual concrete on the conveyor belt 207. By manually rotating the bearing frame 103, precise concrete pouring can be achieved. This method can achieve the effect of uniform pouring in this type of large foundation pit, thereby ensuring the strength of the foundation and reducing personnel risks. This structure also facilitates the later cleaning of the inside of the device.

[0063] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, 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 foregoing 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.
