Description

Technical Field

[0002] In bridge construction, two precast panels need to be connected into a whole using cast-in-place wet joints at the gap between them to form a bridge deck. Fiber concrete is usually used for casting, which can resist cracking of the bridge deck.

[0003] When pouring wet joints in situ, extendable pouring pipes are usually used for pouring. This eliminates the need to hoist the equipment used to prepare concrete onto the bridge deck. Casting pipes generally do not have the function of regulating the pouring flow rate.

[0035] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0036] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0037] like Figure 1 As shown, the present invention provides a fiber concrete preparation and pouring system, comprising: a preparation body 1, used for preparing concrete; a conveying body 2 connected to a discharge port of the preparation body 1, on which a pouring pipe 3 is provided, the conveying body 2 is used to convey the prepared concrete to a position to be poured through the pouring pipe 3; the pouring pipe 3 is provided with an adjustment mechanism 4, the adjustment mechanism 4 is used to squeeze or release the pouring pipe 3;

[0038] like Figure 2 As shown, the adjustment mechanism 4 includes: a bracket 7 for connecting with the casting pipe 3; an adjustment part 8 movably arranged on the bracket 7; and a driving part 9 for driving two movable ends 86 of the adjustment part 8 to squeeze or release the casting pipe 3.

[0039] The prepared concrete of the preparation body 1 is discharged from the discharge port into the conveying body 2. The conveying body 2 pressurizes the concrete to convey it to the position to be poured through the pouring pipe 3. The conveying body 2 conveys the concrete by pressurization. It can adopt any pressurization conveying method in the prior art, and the purpose is to be able to convey the concrete to a higher position for pouring.

[0040] The adjusting mechanism 4 can squeeze and release the pouring pipe 3 according to the needs during concrete pouring. The position where the adjusting mechanism 4 is installed on the pouring pipe 3 is made of hard material, and the position on the pouring pipe 3 squeezed by the adjusting mechanism 4 is made of flexible material. When the pouring pipe 3 is squeezed, the inner diameter of the pouring pipe 3 changes with the squeezing depth, thereby realizing the adjustment of the pouring flow rate; the intermittent squeezing and releasing of the pouring pipe 3 by the adjusting mechanism 4 can generate vibrations on the pouring pipe 3, thereby preventing a large amount of concrete from adhering to the end of the pouring pipe 3 and avoiding blockage.

[0041] Specifically, the portion where the pouring pipe 3 is connected to the bracket 7 is made of a hard material, that is, this portion will not deform, while the portion where the pouring pipe 3 contacts the two movable ends 86 is made of a flexible material, that is, it is easy to deform, thereby achieving an extrusion effect on the pouring pipe 3 through the two movable ends 86. By adjusting the distance between the two movable ends 86, the pouring flow of the pouring pipe 3 can be changed. By controlling the intermittent contact and non-contact between the two movable ends 86 of the adjusting part 8 and the pouring pipe 3 through the driving part 9, a certain vibration effect can be generated on the pouring pipe 3, thereby preventing blockage.

[0042] like Figure 1 As shown, further, the preparation body 1 comprises: a mixing tank 5 and an adding mechanism 6 for adding steel fibers into the mixing tank 5; a fluidity detector is provided in the mixing tank 5, and when the fluidity detector detects that the fluidity of concrete without adding steel fibers is within a preset range, steel fibers are added into the mixing tank 5 through the adding mechanism 6;

[0043] The conditions satisfied by the preset range are: after the steel fiber is mixed with the concrete, the steel fiber will not settle in the concrete, and the fluidity of the concrete after adding the steel fiber can enable the concrete to be poured smoothly.

[0044] The adding mechanism 6 for adding steel fibers can be any device in the prior art, and no limitation is made here.

[0045] When preparing fiber concrete, this embodiment adopts the method of adding steel fibers to make fiber concrete. Since steel fibers are easy to settle in concrete with a large fluidity, that is, when the concrete is poured, the concrete needs time to solidify, and the steel fibers will settle, resulting in uneven distribution in the concrete, affecting the performance of the formed wet joints; steel fibers are not easy to settle in concrete with a small fluidity, but concrete with a small fluidity will cause pouring difficulties. Therefore, before adding steel fibers, it is necessary to detect the fluidity of the concrete through a flow detector. When the fluidity reaches the preset range, steel fibers are added. The fiber concrete formed in this way can prevent the steel fibers from settling and maintain a certain fluidity to ensure smooth pouring.

[0046] like Figure 2 , Figure 6 and Figure 7 As shown, further, the adjusting part 8 includes: at least two limit plates 81, which are arranged on the bracket 7, and a movable part 82 is slidably connected to the limit plate 81; the driving part 9 is connected to the movable part 82, and is used to drive the movable part 82 to move back and forth in a straight line; two extrusion parts 83, which are provided with a first hinge point 84, a second hinge point 85 and a movable end 86, the first hinge point 84 is hinged to the movable part 82, the second hinge point 85 is hinged to the bracket 7, and the movable end 86 is used to contact the casting pipe 3.

[0047] The driving part 9 drives the movable part 82 to move up and down, thereby driving the extrusion part 83 hinged to the movable part 82 to move, so that the movable end 86 moves in the direction close to or away from the casting pipe 3, thereby realizing the extrusion and release of the casting pipe 3; the limit plate 81 is used to limit the distance of the movable part 82 moving up and down, and the second hinge point 85 hinged to the bracket 7 is the force point of the extrusion part 83. When the extrusion part 83 moves, it rotates with the second hinge point 85 as the rotation center.

[0048] like Figure 7 and Figure 8 As shown, further, the extrusion member 83 includes: two rod bodies 831, each rod body 831 is provided with a first hinge point 84 and a second hinge point 85, the first hinge points 84 on the two rod bodies 831 are respectively hinged to the two movable parts 82, and the second hinge points 85 on the two rod bodies 831 are respectively hinged to the two sides of the bracket 7; the two rod bodies 831 are connected by a contact round rod 832 to form a movable end 86, and the contact round rod 832 is rotatably connected to the rod body 831.

[0049] The rod body 831 includes: a first rod segment, a second rod segment and a third rod segment connected in sequence, a first angle is formed between the first rod segment and the second rod segment, and a second angle is formed between the second rod segment and the third rod segment; a second hinge point 85 is arranged at the connection between the first rod segment and the second rod segment, a first hinge point 84 is arranged at one end of the first rod segment away from the second rod segment, and a contact round rod 832 is arranged on the third rod segment; the first hinge point 84 and the second hinge point 85 are holes arranged on the rod body 831.

[0050] The contact round rod 832 is used to contact the casting pipe 3 . In order to reduce the contact friction between the contact round rod 832 and the casting pipe 3 , the contact round rod 832 can rotate relative to the rod body 831 .

[0051] like Figure 7As shown, further, the movable part 82 includes: a support block 821, on which two support rods 822 are hinged, and the two support rods 822 are respectively hinged to the first hinge points 84 of the two extrusion parts 83; the output end of the driving part 9 is connected to the support block 821, and is used to drive the support block 821 to move linearly back and forth on the limiting plate 81.

[0052] A mounting groove is provided on the support block 821, and a hinge rod is provided in the mounting groove. One end of the support rod 822 is rotatably connected to the hinge rod, and the other end is rotatably connected to the first hinge point 84 of the rod body 831; after the driving unit 9 causes the support block 821 to move, it drives the two support rods 822 to move upward. Since the support rod 822 is hinged to the rod body 831, and the rod body 831 is rotatably connected to the bracket 7, the movable end 86 can be driven to rotate with the second hinge point 85 as the rotation center, so that the two movable ends 86 are close to or away from each other.

[0053] like Figure 8 and Fig. 9 As shown, further, a limiting block 823 is provided on the supporting block 821 , and a limiting groove 811 for the limiting block 823 to slide is provided on the limiting plate 81 .

[0054] The limiting groove 811 and the limiting block 823 are used to limit the up and down reciprocating movement of the supporting block 821 .

[0055] The working principle of the adjustment mechanism 4 is as follows: when it is necessary to adjust the distance between the two movable ends 86, taking the reduction of the distance as an example, after the driving unit 9 works, its output end drives the support block 821 to move upward along the limit groove 811, and at the same time drives the two support rods 822 hinged to the support block 821 to move upward. Since the support rod 822 is hinged to the rod body 831, and the rod body 831 is hinged to the bracket 7, when the support block 821 moves upward, it will drive the rod body 831 to rotate along the second hinge point 85, so that the movable end 86 rotates toward the side close to the casting pipe 3, then the distance between the two movable ends 86 is reduced, which can squeeze the casting pipe 3; when the distance between the two movable ends 86 needs to be increased, the support block 821 is driven downward by the driving unit 9, then the corresponding movable end 86 will rotate toward the side away from the casting pipe 3, and the distance between the two movable ends 86 is increased.

[0056] When the casting pipe 3 needs to be vibrated, the driving unit 9 drives the support block 821 to move back and forth within a preset distance, so that the two movable ends 6 intermittently squeeze and release the casting pipe 3.

[0057] In one embodiment, it further includes: a control module that is communicatively connected to the driving part 9 and is used to control the operation of the driving part 9 to adjust the working state of the regulating part 8 .

[0058] The control module is used to control the driving part 9 according to the needs of the casting process, thereby realizing the control of the regulating part 8.

[0059] Furthermore, the control module controls the driving unit 9 including:

[0060] The first control strategy is to make the driving part 9 control the two movable ends 86 of the regulating part 8 to move back and forth between the initial position and the clearing position, thereby vibrating the pouring pipe 3;

[0061] The initial position is the position where the two movable ends 86 are not in contact with the pouring pipe 3; the clearing position is the position where the two movable ends 86 are in contact with the pouring pipe 3 and the two movable ends 86 are at a first distance from each other;

[0062] The first control strategy is generally executed after each pouring stage is completed;

[0063] like Figure 2 The initial position is shown. Figure 3 The figure shows the positions of the two movable ends 86 when the movable ends 86 are in contact with the casting pipe 3 and no extrusion occurs. When the two movable ends 86 are at a first distance from each other, a small extrusion effect is formed on the casting pipe 3, that is, Figure 4 Thus, under the action of squeezing the casting tube 3 and the elastic recovery of the casting tube 3, a vibration is generated, which can remove the concrete attached to the inside;

[0064] The second control strategy is to make the driving part 9 control the two movable ends 86 of the regulating part 8 to be a set distance apart when the pouring flow rate needs to be adjusted, and the set distance corresponds to the pouring flow rate;

[0065] There is a corresponding relationship between the distance between the two movable ends 86 and the distance that the driving part 9 drives the movable member 82 to move, and there is a corresponding relationship between the distance between the two movable ends 86 and the pouring flow rate. Therefore, when the pouring flow rate needs to be adjusted, it is sufficient to adjust the distance that the movable member 82 moves up and down;

[0066] The third control strategy is to make the driving part 9 control the two movable ends 86 of the regulating part 8 to be a second distance apart, so that the casting pipe 3 is closed; wherein the second distance is smaller than the first distance;

[0067] The third control strategy is generally executed after the first control strategy is executed; or it is executed when the pouring pipe 3 needs to be temporarily closed;

[0068] like Figure 5As shown, when the two movable ends 86 are at a second distance from each other, the squeezing effect on the pouring pipe 3 can close the pouring pipe 3, that is, prevent the concrete from flowing out of the pouring pipe 3; this also makes it possible for the pouring pipe 3 to be in a closed state when moving after completing a pouring stage, so as to prevent the concrete remaining in the pouring pipe 3 from falling to a non-pouring position; and, during the pouring process, if the position of the pouring pipe 3 is not moved in time, resulting in a large amount of concrete poured at a certain position being accumulated, the pouring pipe 3 can be closed in time through the third control strategy, and the conveying body 2 will detect the increase in pressure in the pouring pipe 3 and stop conveying in time, so as to prevent a large amount of concrete from overflowing and affecting the construction.

[0069] Through the different control strategies of the driving part 9 by the above control module, the adjustment mechanism 4 can be adapted to multiple usage requirements during the concrete pouring process, thereby improving the efficiency and quality of the concrete pouring construction.

[0070] like Fig.10 As shown, in one embodiment, it also includes: a cleaning body 10, on which a water pipe 11 connected to the pouring pipe 3 is provided; after the concrete pouring is completed, a cleaning water flow is provided to the pouring pipe 3 through the cleaning body 10, and at the same time, the control module adopts a first control strategy to vibrate the pouring pipe 3.

[0071] In order to further prevent the concrete from clogging the casting pipe 3, after the concrete pouring is completed, a high-pressure cleaning water flow can be provided by the cleaning body 10 to flush the casting pipe 3. At the same time, the control module executes the first control strategy to promote the removal of residual concrete in the casting pipe 3 to prevent clogging and facilitate the next use.
