Description

Technical Field

[0001] The invention relates to the technical field of concrete pouring equipment, and in particular to a concrete pouring device and a pouring method. Background Art

[0002] Concrete is a composite material that is both strong and economical, and has been widely used in existing construction projects. Since concrete often needs to be poured from top to bottom, existing concrete buildings often use sky pumps to continuously pump concrete to a high place during construction, and then pour the concrete from top to bottom into the formwork through the pouring pipe to ensure the continuity of pouring. However, the deployment of sky pumps requires a large amount of open space, so it is difficult to be used in the construction of small or closed sites, such as subway station construction, pipe jacking shaft construction, and beam yard prefabricated parts construction.

[0003] For concrete pouring operations in narrow or closed sites, the existing technology generally uses a crane to add a hopper to pour concrete, that is, first put the concrete into the hopper, then use the crane to lift the hopper to the top of the designated pouring position, then open the bottom of the hopper or tilt the hopper to pour the concrete into the designated position. However, this method requires the use of a crane to repeatedly lift the hopper, which has low operating efficiency and certain safety risks in hoisting operations. At the same time, it is also impossible to achieve continuous pouring of concrete, which will have a certain negative impact on the pouring quality of concrete buildings. Therefore, it is urgent to develop a new type of concrete pouring device. Summary of the invention

[0004] The purpose of the present invention is to overcome the technical problems in the prior art of using a crane to add a hopper to carry out concrete pouring operations, in which the crane needs to repeatedly lift the hopper, resulting in low operating efficiency, inability to carry out continuous pouring, and certain safety risks in lifting operations, and to provide a concrete pouring device and a pouring method.

[0005] In a first aspect, the present invention provides a concrete pouring device, comprising:

[0006] The gantry includes a main beam, a pulley and legs connected to both ends of the main beam; the pulley is movably connected to the main beam, the pulley can move along the length direction of the main beam, and a casting pipe is connected to the pulley; a walking mechanism is arranged at one end of the leg away from the gantry, and the walking direction of the walking mechanism is perpendicular to the length direction of the main beam;

[0007] Concrete pump and winding drum, the concrete pump is connected with the gantry, and the winding drum is rotatably connected with the gantry;

[0008] The concrete conveying pipe comprises a first conveying pipe and a second conveying pipe; the first conveying pipe is a flexible hose, one end of the first conveying pipe is connected to the inlet of the casting pipe, the other end of the first conveying pipe bypasses the winding tube and is connected to one end of the second conveying pipe, a rotating joint is arranged between the first conveying pipe and the second conveying pipe; the other end of the second conveying pipe is connected to the discharge port of the concrete pump.

[0009] The concrete pouring device of this scheme arranges the concrete pump, concrete conveying pipe and pouring pipe required for pouring concrete on the gantry; when the walking device drives the gantry to move in a direction perpendicular to the length direction of the main beam, the concrete pump, concrete conveying pipe and pouring pipe can also move along the direction perpendicular to the length direction of the main beam; when the pulley moves along the length direction of the main beam, the pouring pipe can also move along the length direction of the main beam; that is, in this scheme, the pouring pipe can move in two mutually perpendicular directions, so that it can move to the top of various positions under the gantry, so as to realize concrete pouring operations at different positions.

[0010] When the pulley moves along the length direction of the main beam, the distance between the pulley and the pouring pipe connected thereto and the concrete pump will change. In order to maintain the connection between the pouring pipe and the concrete pump, this solution divides the concrete delivery pipe into two sections, wherein the first delivery pipe is a flexible hose wound on a winding drum, and the winding drum can be rotated to release or retract the first delivery pipe of corresponding length, thereby ensuring that the concrete pump is always connected to the pouring pipe, and making the distance between the two ends of the concrete delivery pipe adapt to the distance between the pouring pipe and the concrete pump, thereby avoiding the situation where the movement of the pulley is hindered by the concrete delivery pipe, or the concrete delivery pipe is damaged by the tension of the pulley.

[0011] When pouring concrete, as mentioned above, this solution can ensure that the concrete pump is always connected to the pouring pipe. Therefore, this solution can continuously pump concrete to the pouring pipe through the concrete pump, so that the concrete can be continuously poured into the designated position, thereby realizing continuous pouring of concrete and ensuring the pouring quality of concrete, avoiding the situation where the existing technology can only pour concrete one bucket at a time, resulting in the need for repeated lifting operations of the bucket, low work efficiency and certain safety risks of the lifting operation, and the pouring quality of concrete will also be negatively affected.

[0012] Preferably, the gantry is also connected to a guide device, which includes a support frame and a guide; the support frame is arranged on one side of the winding drum along the radial direction of the winding drum; the guide is movably connected to the side of the support frame facing the winding drum, and the position of the guide along the axial direction of the winding drum is adjustable; a first guide roller group is arranged on the guide, and the first guide roller group abuts against the side wall of the first conveying pipe.

[0013] When the winding drum rotates and releases or retracts part of the first conveying tube, the first conveying tube will move and shake relative to the gantry, causing the first conveying tube to scratch the components on the gantry and be damaged, and this situation is particularly obvious at the starting position where the first conveying tube leaves the winding drum; therefore, the present scheme arranges a guide on one side of the winding drum, and makes the first guide roller group on the guide abut against the first conveying tube, which can convert the sliding friction between the first conveying tube and the gantry components into rolling friction, thereby avoiding direct scratching of the first conveying tube and the gantry, and further reducing the probability of damage to the first conveying tube.

[0014] When the winding drum rotates and releases or retracts part of the first conveying tube, the starting position of the first conveying tube leaving the winding drum will change along the axial direction of the winding drum. Therefore, the present scheme further enables the guide to be movably connected to the support frame, so that the guide can move along the axial direction of the winding drum accordingly as the first conveying tube is released or retracted (the driving force is the support reaction force generated by the side wall of the first conveying tube on the first guide roller group), thereby maintaining the position of the guide at the starting position of the first conveying tube leaving the winding drum, that is, the position where the first conveying tube is most likely to be scratched against the gantry frame components, thereby ensuring that the guide device can maintain a good guiding effect throughout the process of the winding drum releasing or retracting the first conveying tube.

[0015] Preferably, a partition is provided on the side wall of the winding drum, and the partition is spirally arranged along the axial direction of the winding drum, and the lead of the partition matches the diameter of the first conveying pipe.

[0016] The present solution adds a spiral partition on the side wall of the winding drum, which can limit the first conveying tube, so that the first conveying tube can be wound into a standard spiral shape on the side wall of the winding drum as much as possible, avoiding the first conveying tube from being crookedly wound on the winding drum; on the one hand, it can make the length of the first conveying tube released or retracted accurately match the number of rotations of the winding drum, so as to facilitate the staff or controller to accurately release or retract the first conveying tube of corresponding length according to the moving distance of the pulley, thereby avoiding the first conveying tube from being over-tensioned or over-relaxed; on the other hand, it can also avoid the radial accumulation of two adjacent sections of the first conveying tube along the winding drum when the first conveying tube is crookedly wound on the side wall of the winding drum, resulting in the radial size of the combination formed by the first conveying tube and the winding drum becoming larger, thereby causing the combination to interfere with the gantry frame components, and even the rotational freedom of the winding drum being stuck by the first conveying tube.

[0017] Preferably, a second guide roller set is further provided on the guide, and the second guide roller set abuts against the side wall of the partition.

[0018] In this solution, a second guide roller group abutting against the partition is added to the guide. When the winding drum rotates, the guide will not only be subjected to the support reaction force transmitted from the side wall of the first conveying tube to the first guide roller group, but also to the support reaction force transmitted from the partition to the second guide roller group. This can more reliably ensure that the guide can move accordingly along the axial direction of the winding drum as the winding drum rotates, so as to better guide the first conveying tube.

[0019] Preferably, a bracket is movably connected to the main beam, and the position of the bracket along the length direction of the main beam is adjustable; the bracket is used to support the first conveying pipe; the number of the brackets is at least two, and the brackets are spaced apart along the length direction of the main beam; a traction rope is provided between two adjacent brackets, and a traction rope is also provided between at least one bracket and the pulley.

[0020] In this solution, at least two brackets are movably connected on the main beam. When the pulley moves away from the concrete pump along the length direction of the main beam, the bracket will move accordingly under the traction of the traction rope, thereby ensuring that there is at least one bracket supporting the first conveying pipe for every length of the traction rope along the length direction of the main beam, thereby avoiding the first conveying pipe from bending due to its own weight and the weight of the concrete, resulting in negative impacts on the stress state of the first conveying pipe and the flow of concrete; and when the pulley approaches the concrete pump along the length direction of the main beam, the traction rope can bend, so that the distance between the two adjacent brackets can be reduced again under the push of the pulley, and the movement of the pulley will not be hindered.

[0021] Preferably, the bracket comprises a support ring, and the first conveying tube passes through the support ring; the inner wall of the support ring is provided with a third guide roller group, and the third guide roller group abuts against the side wall of the first conveying tube.

[0022] The present solution provides a specific bracket form, which can limit the first conveying tube along the circumference of the first conveying tube through the support ring, thereby preventing the first conveying tube from falling out of the bracket; at the same time, the third guide roller group can also prevent the first conveying tube from being scratched and damaged against the inner wall of the support ring.

[0023] Preferably, it also includes a driving device and a controller, the driving device is used to drive the winding drum to rotate; the controller is communicatively connected with the driving device and the pulley, and the controller is used to control the rotation direction and number of rotations of the driving device according to the moving distance of the pulley.

[0024] This solution actively controls the rotation of the winding drum through a driving motor and a controller, so that the first conveying pipe of corresponding length can be released or retracted according to the moving distance of the pulley, thereby avoiding the first conveying pipe from being passively tensioned by the pulley. This can prevent the first conveying pipe from obstructing the movement of the pulley, allowing the pulley to move more quickly and smoothly to change the casting position, and can also avoid the first conveying pipe from being damaged during tensioning.

[0025] Preferably, the casting pipe is divided into at least two sections along its length direction, and two adjacent sections are detachably connected.

[0026] This solution can facilitate workers to change the length of the pouring pipe by disassembling and assembling segments, thereby changing the falling height of the concrete according to actual pouring needs.

[0027] Preferably, a sawtooth bar is connected to the gantry, the sawtooth bar comprises a forward section and a reverse section with opposite sawtooth directions, and the forward section and the reverse section are alternately arranged along the length direction of the sawtooth bar;

[0028] At least two connecting pieces are arranged at intervals along the length direction of the sawtooth bar, and the connecting pieces include latch teeth and a connecting portion. At least one connecting piece is engaged with the forward section through the corresponding latch teeth, and at least one connecting piece is engaged with the reverse section through the corresponding latch teeth; the connecting portion is connected to the concrete pump.

[0029] In this solution, the connecting piece used to connect to the concrete pump is clamped on the sawtooth bar through the clamping teeth. The operator can select the number of connecting pieces according to the needs, and the distance between two adjacent connecting pieces along the length direction of the sawtooth bar is adjustable, so that it can be used to adapt to different models of concrete pumps, making this solution more versatile.

[0030] At the same time, the sawtooth bar of the present solution includes alternately arranged forward sections and reverse sections. No matter in which direction the concrete pump is subjected to external force along the length direction of the sawtooth bar, at least one of the forward section and the reverse section can block the concrete pump, so that the present solution can more reliably limit the concrete pump.

[0031] In a second aspect, the present invention provides a concrete pouring method, which is applied to a concrete pouring device of the present invention, comprising the following steps:

[0032] Input concrete into the concrete pump, pump the concrete to the pouring pipe through the concrete pump, and pour the concrete to the designated position through the pouring pipe;

[0033] The pulley is moved in a first direction to adjust the casting position of the casting pipe along the first direction, and the first direction is parallel to the length direction of the main beam; and / or the walking mechanism drives the gantry to move in a second direction to adjust the casting position of the casting pipe along the second direction, and the second direction is perpendicular to the length direction of the main beam.

[0034] Compared with the prior art, the present invention has the following beneficial effects:

[0035] 1. The present invention provides a concrete pouring device, which can provide the pouring pipe with freedom of movement in two directions by arranging a concrete pump and a pouring pipe on a gantry, and a concrete conveying pipe between the pouring pipe and the concrete pump includes a first conveying pipe wound on a winding drum, and always keeps the pouring pipe connected to the concrete pump, thereby realizing continuous pouring operations at various positions below the gantry, without the need to repeatedly lift the hopper as in the prior art, so that the present invention can achieve higher work efficiency, higher pouring quality and avoid safety risks of lifting operations.

[0036] 2. The present invention provides a concrete pouring method. By using the concrete pouring device of the present invention, continuous pouring at various positions below the gantry can be achieved without repeatedly lifting the hopper, which has higher work efficiency and higher pouring quality, and can avoid the safety risks of repeated lifting operations.

[0072] Example 1

[0073] like Figures 1 to 18 As shown, a concrete pouring device includes a gantry, a concrete pump 2, a winding drum 3 and a concrete conveying pipe.

[0074] The gantry comprises a main beam 11 , a pulley 12 and supporting legs 13 connected to both ends of the main beam 11 .

[0075] The pulley 12 is movably connected to the main beam 11 so that the pulley 12 can move along a first direction parallel to the length direction of the main beam 11; the specific form of the movable connection between the pulley 12 and the main beam 11 includes but is not limited to a pulley rail mechanism, a rail slider mechanism, a screw mechanism or a gear rack mechanism; the pulley 12 is connected to a casting pipe 5.

[0076] A walking mechanism 14 is provided at one end of the support leg 13 away from the gantry, and the walking direction of the walking mechanism 14 is along the second direction, which is perpendicular to the length direction of the main beam 11; the specific form of the walking mechanism 14 includes but is not limited to walking wheels, crawlers or mechanical legs.

[0077] The concrete pump 2 is connected to the gantry, and the specific connection position is not limited, for example Figure 1 and Figure 4 As shown, the concrete pump 2 can be connected to the bottom of one of the legs 13 to facilitate the delivery of concrete to the concrete pump 2 .

[0078] The winding drum 3 is rotatably connected to the gantry, and the specific connection position is not limited, for example Figure 1As shown, the concrete pump 2 can be connected to the top of one of the legs 13 to reduce the proportion of the flexible hose (second delivery pipe 42) in the concrete delivery pipe; the direction of the rotation axis of the winding drum 3 is not limited and can be set in the first direction or the second direction.

[0079] The concrete delivery pipe includes a first delivery pipe 41 and a second delivery pipe 42; the first delivery pipe 41 is a flexible hose, such as a rubber hose or a polyurethane hose; one end of the first delivery pipe 41 is connected to the inlet of the casting pipe 5, and the other end of the first delivery pipe 41 bypasses the winding tube 3 and is connected to one end of the second delivery pipe 42. A rotary joint is provided between the first delivery pipe 41 and the second delivery pipe 42, and the rotary joint can directly adopt an existing product; the other end of the second delivery pipe 42 is connected to the discharge port of the concrete pump 2, and the second delivery pipe 42 can adopt either a flexible hose or a hard pipe, such as a steel pipe and a polyvinyl chloride pipe.

[0080] In an optional embodiment, a guiding device is also connected to the gantry, and the guiding device includes a support frame 61 and a guide 62; the support frame 61 is arranged on one side of the winding drum 3 along the radial direction of the winding drum 3; the guide 62 is movably connected to the side of the support frame 61 facing the winding drum 3, so that the position of the guide 62 along the axial direction of the winding drum 3 is adjustable; a first guide roller group 621 is arranged on the guide 62, and the first guide roller group 621 abuts against the side wall of the first conveying pipe 41.

[0081] In the above embodiment, the movable connection between the guide 62 and the support frame 61 includes but is not limited to a pulley rail mechanism, a rail slider mechanism, a screw mechanism or a gear rack mechanism. Figure 12 to Figure 13 As shown, a movable track 611 whose length is arranged along the axial direction of the winding drum 3 is provided on the support frame 61, and a movable roller group 623 is correspondingly arranged on the guide 62. The movable roller group 623 can roll on the movable track 611, thereby ensuring that the guide 62 is always located at the starting position where the first conveying tube 41 leaves the winding drum 3 along the axial direction of the winding drum 3.

[0082] In the above embodiment, the number of the moving tracks 611 on the support frame 61 may be one or more; for example, Figure 12 to Figure 13 In the embodiment, three movable rails 611 are arranged on the support frame 61 in parallel and at intervals.

[0083] In the above embodiment, when the number of the movable tracks 611 on the support frame 61 is greater than one, the movable tracks 611 may include at least two different orientations, and two groups of movable roller groups 623 with different orientations are correspondingly provided on the guide 62 to provide support and limit the guide 62 from different directions; for example Fig.13As shown, among the three movable tracks 611, the first tracks are located on both sides, and the normal of the first track is set along the third direction, which is used to support the guide 62 from both sides of the third direction, so as to prevent the guide 62 from falling under the action of gravity; the second track is located in the middle, and the normal of the second track is set along the radial direction of the winding drum 3, which is used to support the guide 62 along the radial direction of the winding drum 3, so as to ensure that the guide 62 can fully press against the first conveying pipe 41; two movable roller groups 623 with different orientations are correspondingly arranged on the guide 62, wherein the roller axis direction of the movable roller group 623 adapted to the first track is perpendicular to the third direction and the axis direction of the winding drum 3, and the roller axis direction of the movable roller group 623 adapted to the second track is parallel to the third direction.

[0084] In the above embodiment, the rollers in the movable roller group 623 can be grooved wheels, such as V-shaped grooved wheels or U-shaped grooved wheels, and the groove shape of the grooved wheels matches the cross-sectional shape of the movable rail 611, so that they can be embedded in the movable rail 611 to obtain a more reliable limiting effect and prevent the limiter from separating from the support frame 61.

[0085] In the above embodiment, the rollers in the first guide roller group 621 include at least two rollers, and at least one roller abuts against one side of the first conveying tube 41 along the axial direction of the winding drum 3, and at least one roller abuts against the other side of the first conveying tube 41 along the axial direction of the winding drum 3. Therefore, no matter whether the first conveying tube 41 is being retracted or released by the winding drum 3, a support reaction force can be generated to the roller on the corresponding side through its side wall, thereby driving the guide 62 to follow the movement of the first conveying tube 41.

[0086] In an optional embodiment, a partition 31 is provided on the side wall of the winding drum 3, and the partition 31 is spirally arranged along the axial direction of the winding drum 3, and the lead of the partition 31 matches the diameter of the first conveying pipe 41. The partition 31 can be made of a hard material, such as a steel plate or an aluminum plate, and is used to reliably separate the sections of the first conveying pipe 41 and provide a reliable walking plane for the subsequent second guide roller group 622.

[0087] In an optional embodiment, the winding drum 3 is a hollow cylindrical structure, thereby reducing the weight of the winding drum 3 and achieving lightweight winding drum 3; the center of the winding drum 3 is connected to a core shaft through spokes, and the winding drum 3 is rotatably connected to the gantry through the core shaft.

[0088] In the above embodiment, a connecting through hole 32 is provided on the side wall of the winding drum 3, and an elbow pipe 33 is provided inside the winding drum 3; the elbow pipe 33 includes a radial section arranged along the radial direction of the winding drum 3, and an axial section arranged coaxially with the axis of the winding drum 3; one end of the radial section passes through the connecting through hole 32 and is connected to the first conveying pipe 41, and the other end is connected to one end of the axial section; the other end of the axial section is connected to the second conveying pipe 42 through a rotating joint, so that when the winding drum 3 rotates, the position of the axial section relative to the winding drum 3 can remain unchanged, so that it can be convenient for it to maintain connection with the second conveying pipe 42 through the rotating joint.

[0089] In an optional implementation, the outer side wall of the winding drum 3 may also be provided with anti-slip textures to increase the friction between the winding drum 3 and the first conveying tube 41 .

[0090] In an optional implementation, a second guide roller set 622 is further provided on the guide 62 , and the second guide roller set 622 abuts against the side wall of the partition 31 along the axial direction of the winding drum 3 .

[0091] In the above embodiment, the second guide roller group 622 may include one or more rollers; for example Fig.14 As shown, the second guide roller set 622 includes four rollers.

[0092] In the above embodiment, the rollers in the second guide roller group 622 can be grooved wheels, such as V-shaped grooved wheels or U-shaped grooved wheels, and the groove shape of the grooved wheels matches the cross-sectional shape of the partition 31, so that they can be embedded in the partition 31 to obtain a more reliable limiting effect.

[0093] In an optional embodiment, a bracket 7 is also movably connected to the main beam 11, so that the position of the bracket 7 along the length direction of the main beam 11 is adjustable; the bracket 7 is used to support the first conveying pipe 41; the number of the brackets 7 is at least two, and the brackets 7 are spaced apart along the length direction of the main beam 11; a traction rope 73 is provided between each adjacent bracket 7, and a traction rope 73 is also provided between at least one bracket 7 (for example, the bracket 7 closest to the pulley 12) and the pulley 12.
