Description

TECHNICAL FIELD

[0001] The utility model relates to filter equipment technical field, especially relate to a large -scale flat -bottomed tank concrete leveling layer construction device. BACKGROUND

[0002] At present, large flat bottom storage tank for storing liquefied natural gas or low temperature liquefied medium such as liquid ethylene is more and more widely used, and with the large-scale development of the storage tank, the diameter of the storage tank is larger and larger, and the construction area of the bottom insulation layer is also greatly increased, and the requirement of the bottom insulation layer construction is also higher and higher.The bottom insulation layer of the storage tank is composed of concrete leveling layer, foam glass brick, asphalt felt and other materials, and the materials are constructed and assembled on site.

[0003] In the traditional technology, the concrete leveling layer construction mostly uses concrete pump truck to pump concrete material into the storage tank through telescopic and flexible distribution rod.Due to the small size of the temporary door of the storage tank, the too long length of the distribution rod of the concrete pump truck and the limitation of the site of the concrete pump truck, the concrete pump truck can only pump the concrete material to the area from the center of the storage tank to the temporary door. Then the workers transfer the concrete to the four sides of the tank by small transport bucket car and then lay the concrete flat. Due to the large-scale development of the storage tank, the concrete transfer workload is more and more, and the wheels of the small transport bucket car may damage the foam glass brick and cause the glass brick to shift during the transfer of the concrete to the four sides of the storage tank, which may cause the gap between the foam glass bricks to be too large and affect the effect of the bottom insulation layer. Therefore, a large flat bottom tank concrete leveling layer construction device is needed to reduce labor intensity and avoid damage to the bottom insulation layer. CONTENT OF THE UTILITY MODEL

[0040] The large flat bottom tank concrete leveling layer construction device of the present application is mainly used for the concrete leveling layer construction of the heat insulation layer at the bottom of a large flat bottom low-temperature storage tank. As shown in the drawings, the bottom of a large flat bottom low-temperature storage tank 10 is usually provided with a multi-layer structure heat insulation layer 40. For example, the heat insulation layer 40 provided on the foundation pile cap 30 of the storage tank 10 can include concrete leveling layers 41, 43, 44 and 46, and foam glass brick layers 42 and 45 which are stacked in sequence.

[0041] Please refer to Figure 1 and Figure 2 As shown in

[0042] One end of the first communicating pipe 200 is communicated with the second end through an elbow, and the first communicating pipe 200 extends in the XY plane at an angle with the X axis. One end of the second communicating pipe 300 is communicated with the other end of the first communicating pipe 200 through an elbow, and the second communicating pipe 300 extends in the XZ plane at an angle with the X axis and upward. One end of the output pipe 400 is communicated with the other end of the second communicating pipe 300 through an elbow, and the output pipe 400 is arranged in the horizontal direction, and the output pipe 400 can make a circular motion around the Z axis, and the other end of the output pipe 400 is used for outputting concrete downward.

[0043] It should be noted that, in the construction process of the storage tank 10, the temporary door 20 is a very important part in the construction process of the storage tank 10, which plays a crucial role in subsequent cold preservation in the tank, installation of the inner tank, and construction of the pipeline in the tank. Among them, the cold preservation construction in the tank includes the construction of the heat insulation layer 40 at the bottom of the storage tank 10. That is, the construction of each concrete leveling layer in the heat insulation layer 40 is carried out through the temporary door 20.

[0044] It should be noted that, as shown in Figure 1 and Figure 2 In the embodiments of the present application, the X axis direction can be a horizontal axis direction parallel to the connecting line of the center of the bottom edge of the temporary door 20 and the center of the bottom surface of the storage tank 10.

[0045] As shown in Figure 1 and Figure 2 The input pipe 100 is a hard pipe arranged in the X axis direction, which is mainly used for conveying concrete outside the storage tank 10 to the target area inside the storage tank 10 through the temporary door 20. Among them, the first end of the input pipe 100 can be connected with the discharge pipe of the concrete pump equipment. The second end of the input pipe 100 can be inserted into the inside area of the tank wall opposite to the temporary door 20 in the storage tank 10.

[0046] Preferably, the axis of the input pipe 100 intersects the central axis of the storage tank 10. Thus, the input pipe 100 can extend into the tank along the longest path to the area inside the tank wall opposite the temporary door 20. Therefore, the concrete can be delivered to the innermost position in the tank through the input pipe 100, so that the construction can be carried out step by step from the innermost position to the outside of the tank, ensuring the continuity of the construction and avoiding reciprocating construction inside and outside the tank.

[0047] In the present application, the length of the input pipe 100 is adjustable. Thus, the construction personnel can change the length of the input pipe 100 as needed to achieve the purpose of gradually pouring and constructing from the innermost position to the outside of the tank.

[0048] Referring to Figure 1 For example, the input pipe 100 includes a plurality of first straight pipe segments 110 and a connecting clamp 120 connecting adjacent two first straight pipe segments 110. Each first straight pipe segment 110 can be a carbon steel pipe. The connecting clamp 120 can be a steel clamp. The adjacent two first straight pipe segments 110 can be tightly fixed by the connecting clamp 120 to achieve the purpose of quick disassembly, thereby facilitating the adjustment of the length of the input pipe 100.

[0049] More specifically, each first straight pipe segment 110 can be provided with a connecting ring at each end, and the outer periphery of the connecting ring matches the inner groove of the connecting clamp 120. The connecting clamp 120 can be arranged around the outer periphery of the two connecting rings of the adjacent two first straight pipe segments 110 to fix and connect the adjacent two first straight pipe segments 110. In the present embodiment, the connecting clamp 120 and the end of each first straight pipe segment 110 are connected to achieve quick disassembly and fixed connection of the plurality of first straight pipe segments 110, thereby facilitating the construction personnel to quickly adjust the length of the input pipe 100 as needed, and facilitating the improvement of construction convenience and the acceleration of construction progress.

[0050] In other embodiments, the end of each first straight pipe segment 110 can also be provided with a connecting flange, and the connecting flanges of the adjacent two first straight pipe segments 110 can be connected by bolts to achieve quick disassembly and fixed connection.

[0051] Referring to Figure 1 In an embodiment, the construction device further includes a plurality of support brackets 700, which are arranged at intervals along the length direction of the input pipe 100, and the plurality of support brackets 700 are used to support the input pipe 100 together. For example, the support bracket 700 can be a structure substantially in the shape of a "door" formed by welding angle steel and steel plates. The input pipe 100 can be supported and placed on the top of the plurality of support brackets 700 to avoid the situation that the input pipe 100 collapses due to being too long. Moreover, the input pipe 100 can be supported and placed by the plurality of support brackets 700 to keep the input pipe 100 level with the discharge pipe of the concrete pump equipment, thereby ensuring the smooth delivery of the concrete.

[0052] For the convenience of description, it is defined that the elbow connecting the input pipe 100 and the first communicating pipe 200 is referred to as the first elbow 51, the elbow connecting the first communicating pipe 200 and the second communicating pipe 300 is referred to as the second elbow 52, and the elbow connecting the second communicating pipe 300 and the output pipe 400 is referred to as the third elbow 53.

[0053] As shown in Figure 2 , one end of the first communicating pipe 200 is communicated with the second end of the input pipe 100 through the first elbow 51, and the other end is communicated with the second communicating pipe 300 through the second elbow 52.

[0054] The first elbow 51 can be an L-shaped elbow or a V-shaped elbow, etc., which is used to change the direction of the first communicating pipe 200. For example, the first communicating pipe 200 can be a rigid pipe arranged to extend at an angle to the X-axis in the XY plane. The first communicating pipe 200 is mainly used to deliver the concrete to one side of the input pipe 100 for pouring. For example, as shown in Figure 2 , the first communicating pipe 200 can be arranged to extend along the Y-axis direction, which is at a right angle to the input pipe 100. Alternatively, the first communicating pipe 200 can be arranged at an angle of 120° to the input pipe 100. In other words, the first communicating pipe 200 can be generally arranged to extend horizontally along the Y-axis direction, but the angle between the first communicating pipe 200 and the input pipe 100 can not be a right angle. The angle between the first communicating pipe 200 and the input pipe 100 can also be arranged to be an acute angle or an obtuse angle, as long as the purpose of delivering the concrete to one side of the input pipe 100 for pouring can be achieved.

[0055] It should be noted that during construction, the first communicating pipe 200 can be arranged on either side of the input pipe 100 as needed to pour the side area of the input pipe 100.

[0056] In other embodiments, the construction device can also be configured with two first communicating pipes 200. At the same time, the first elbow 51 adopts a T-shaped tee elbow to achieve the purpose of pouring on both sides of the input pipe 100 at the same time.

[0057] In one embodiment, the input pipe 100 and the first communicating pipe 200 are connected in a quick release manner. That is, the input pipe 100 and the first elbow 51 are connected in a quick release manner, and the first elbow 51 and the first communicating pipe 200 are connected in a quick release manner. For example, the end of the input pipe 100 and the end of the first elbow 51 can be quickly clamped and fixed by using a clamp. The end of the first elbow 51 and the end of the first communicating pipe 200 can also be quickly clamped and fixed by using a clamp.

[0058] Referring to Figure 1In one embodiment, the length of the first communicating pipe 200 is adjustable. Thus, the length of the first communicating pipe 200 can be changed by the construction personnel as needed to achieve the purpose of pouring concrete to a region far away from the side of the input pipe 100.

[0059] For example, the first communicating pipe 200 can include a plurality of second straight pipe segments 210, wherein each second straight pipe segment 210 can be a carbon steel pipe. Any two adjacent second straight pipe segments 210 are detachably fixedly connected. For example, the opposite ends of the two adjacent second straight pipe segments 210 can be quickly clamped and fixed by using a clamp.

[0060] Of course, in other embodiments, the first communicating pipe 200 can also be a straight pipe with a fixed length, and the length thereof can be set as needed.

[0061] As shown in FIG. 1, the second communicating pipe 300 is connected to the first communicating pipe 200 through a second elbow 52 at one end and connected to an output pipe 400 through a third elbow 53 at the other end. The second elbow 52 can be an L-shaped elbow or a V-shaped elbow, etc., which is used to change the direction of the second communicating pipe 300. For example, the second communicating pipe 300 can be a rigid pipe extending upward at an angle with the X axis in the XZ plane. The second communicating pipe 300 is mainly used to lift the concrete to a certain height to achieve pouring. The second communicating pipe 300 can be a carbon steel pipe. Figure 1 For example, as shown in FIG. 1, the second communicating pipe 300 can be arranged to extend upward along the Z axis direction, and the second communicating pipe 300 is perpendicular to the first communicating pipe 200 and the input pipe 100. Alternatively, the second communicating pipe 300 can be arranged at an angle of 100° with the first communicating pipe 200. In other words, the second communicating pipe 300 can be generally arranged to extend upward along the Z axis direction, but the angle between the second communicating pipe 300 and the first communicating pipe 200 can not be a right angle. The angle between the second communicating pipe 300 and the first communicating pipe 200 can also be arranged to be an acute angle or an obtuse angle, as long as the purpose of lifting the concrete upward to a certain height can be achieved.

[0062] Figure 1 In one embodiment, the first communicating pipe 200 and the second communicating pipe 300 are quickly detachable. That is, the first communicating pipe 200 and the second elbow 52 are quickly detachable, and the second elbow 52 and the second communicating pipe 300 are quickly detachable. For example, the end of the first communicating pipe 200 and the end of the second elbow 52 can be quickly clamped and fixed by using a clamp. The end of the second elbow 52 and the end of the second communicating pipe 300 can also be quickly clamped and fixed by using a clamp.

[0063] In one embodiment, the first communicating pipe 200 and the second communicating pipe 300 are quickly detachable. That is, the first communicating pipe 200 and the second elbow 52 are quickly detachable, and the second elbow 52 and the second communicating pipe 300 are quickly detachable. For example, the end of the first communicating pipe 200 and the end of the second elbow 52 can be quickly clamped and fixed by using a clamp. The end of the second elbow 52 and the end of the second communicating pipe 300 can also be quickly clamped and fixed by using a clamp.

[0064] ​It can be understood that the second communication pipe 300 can be a straight pipe with a fixed length, and the length can be set as required. Alternatively, the second communication pipe 300 can also be assembled by a plurality of straight pipe segments.

[0065] Referring to Figure 1 and Figure 2 In one embodiment, the construction device further comprises a support assembly 600 corresponding to the second communication pipe 300. The support assembly 600 is used to support the second communication pipe 300, so that the second communication pipe 300 remains to extend upward. Thus, by providing the support assembly 600, the fixed state of the upward extension of the second communication pipe 300 can be ensured, the stable delivery of the second communication pipe 300 can be ensured, and the use reliability of the construction device can be improved. In the following embodiments, the specific structure of the support assembly 600 is illustrated by taking the upward extension of the second communication pipe 300 along the vertical direction as an example.

[0066] As Figure 2 shown, in one embodiment, the support assembly 600 can comprise a support cylinder 610, the axial direction of the support cylinder 610 is arranged along the Z-axis direction, and the support cylinder 610 is sleeved on the outside of the second communication pipe 300. For example, the support cylinder 610 comprises a first arc-shaped plate and a second arc-shaped plate connected oppositely. The opposite surfaces of the first arc-shaped plate and the second arc-shaped plate are arc surfaces matched with the outer circumferential surface of the second communication pipe 300. The opposite surfaces of the second arc-shaped plate and the first arc-shaped plate are arc surfaces matched with the outer circumferential surface of the second communication pipe 300. Thus, when the first arc-shaped plate and the second arc-shaped plate are connected oppositely, they can effectively define the second communication pipe 300.

[0067] The connection mode of the first arc-shaped plate and the second arc-shaped plate oppositely can be that one side of the first arc-shaped plate is hinged to one side of the second arc-shaped plate. For example, one side of the first arc-shaped plate and one side of the second arc-shaped plate can be hingedly connected through a hinge.

[0068] The other side of the first arc-shaped plate and the other side of the second arc-shaped plate can be detachably connected. For example, the other side of the first arc-shaped plate and the other side of the second arc-shaped plate can respectively protrude lugs, and connection holes are respectively formed in the two lugs. By using a fastener such as a bolt to pass through the connection holes in the two lugs, the detachable fixed connection of the other side of the first arc-shaped plate and the other side of the second arc-shaped plate can be achieved.

[0069] In this embodiment, by hingedly connecting one side of the first arc-shaped plate to one side of the second arc-shaped plate and detachably connecting the other side of the first arc-shaped plate to the other side of the second arc-shaped plate, the support cylinder 610 can be quickly and fixedly installed on the outer circumference of the second communication pipe 300, and it is convenient to disassemble, thereby facilitating the operation of the construction personnel.

[0070] As Figure 2As shown, the support assembly 600 can include a plurality of inclined supports 620. The plurality of inclined supports 620 are arranged along the circumference of the support cylinder 610 and are disposed at the outer circumference of the support cylinder 610. The plurality of inclined supports 620 are used to jointly support the support cylinder 610, so that the axial direction of the support cylinder 610 can be kept consistent with the direction of the Z axis. Each inclined support 620 can be made of an angle steel. The position of the support cylinder 610 can be fixed by the inclined supports 620, and the support limiting capability of the support assembly 600 is improved.

[0071] As shown, Figure 1 One end of the output pipe 400 is communicated with the second communication pipe 300 through a third elbow 53, and the other end is used to output concrete downward. The third elbow 53 can be an L-shaped elbow or a V-shaped elbow, etc., which is used to change the direction of the output pipe 400. For example, the output pipe 400 can be a rigid pipe arranged in the horizontal direction. The output pipe 400 is mainly used to pour concrete in a certain range. The output pipe 400 can be made of a carbon steel pipe. The output pipe 400 can be a straight pipe with a fixed length, and the length can be set as needed. Alternatively, the output pipe 400 can also be assembled by a plurality of straight pipe segments.

[0072] In this application, the output pipe 400 can make a circular motion around the Z axis. Specifically, the output pipe 400 can make a circular motion in the horizontal direction with the end connected to the third elbow 53 as the center and the length of the output pipe 400 as the radius. Thus, the output pipe 400 can pour concrete in a circular area, effectively increasing the pouring area of the construction device.

[0073] Referring to Figure 1 In one embodiment, the second communication pipe 300 includes a first pipe body 310 and a second pipe body 320 arranged coaxially, and a rotary joint 330 connected between the first pipe body 310 and the second pipe body 320. The lower end of the first pipe body 310 is connected with the first communication pipe 200 through a second elbow 52, the upper end of the first pipe body 310 is connected with the lower end of the second pipe body 320 through the rotary joint 330, and the upper end of the second pipe body 320 is connected with the output pipe 400 through a third elbow 53. The rotary joint 330 can be a pipe rotary joint, which can realize the relative rotation of the connected pipes and achieve the purpose of conveying materials. Thus, the second pipe body 320 can rotate around the Z axis relative to the first pipe body 310 through the rotary joint 330, so as to drive the output pipe 400 to make a circular motion around the Z axis.

[0074] In this embodiment, the second communication pipe 300 is arranged to include the first pipe body 310, the second pipe body 320 and the rotary joint 330. The second pipe body 320 can rotate around the Z axis under the action of the rotary joint 330, so as to drive the output pipe 400 to make a circular motion around the Z axis.

[0075] In other embodiments, the second communication pipe 300 can be a whole hard pipe. Meanwhile, a rotary joint 330 is arranged between the second communication pipe 300 and the third elbow 53, so that the third elbow 53 and the output pipe 400 can make circumferential motion around the Z axis under the action of the rotary joint 330.

[0076] In an embodiment, the second communication pipe 300 and the output pipe 400 are connected in a quick release manner. That is, the second communication pipe 300 and the third elbow 53 are connected in a quick release manner, and the third elbow 53 and the output pipe 400 are connected in a quick release manner. For example, the end of the second communication pipe 300 and the end of the third elbow 53 can be quickly fixed by a clamp. The end of the third elbow 53 and the end of the output pipe 400 can also be quickly fixed by a clamp.

[0077] Referring to Figure 1 In an embodiment, the construction device further comprises an output hose 500 connected to the output pipe 400 away from the second communication pipe 300 through a fourth elbow 54. The fourth elbow 54 can be an L-shaped elbow or a V-shaped elbow, etc., which is used to transition and connect the output hose 500, so that the output hose 500 can output concrete downward.

[0078] The output hose 500 can be a rubber pipe. The rubber pipe can be sleeved on one end of the fourth elbow 54, and the rubber pipe and the end of the fourth elbow 54 are tightly fixed by a steel wire or a clamp.

[0079] The fourth elbow 54 and the output pipe 400 are connected in a quick release manner. For example, the end of the output pipe 400 and the end of the fourth elbow 54 can be quickly fixed by a clamp.

[0080] In this embodiment, by arranging the output hose 500, since the output hose 500 has flexibility, the pouring direction can be arbitrarily changed, thereby further increasing the concrete pouring area of the construction device.

[0081] Referring to Figure 1 and Figure 2 When the construction device of the embodiment is used, the first end of the input pipe 100 is stretched out of the temporary door 20 of the storage tank 10 and is quickly connected to the discharge pipe of the concrete pump equipment through a steel clamp. The second end of the input pipe 100 is stretched into the storage tank 10 until it is connected to the tank wall near the side of the temporary door 20 of the storage tank 10. The first communication pipe 200 is connected to the second end of the input pipe 100 through the first elbow 51. The second communication pipe 300 is connected to the first communication pipe 200 through the second elbow 52. The output pipe 400 is connected to the second communication pipe 300 through the third elbow 53. The output hose 500 is connected to the output pipe 400 through the fourth elbow 54.

[0082] The input pipe 100 is horizontally supported on each support bracket 700 along the X-axis direction. The second communication pipe 300 can be vertically upward arranged along the Z-axis direction and supported and fixed by the support assembly 600. The first communication pipe 200 can be horizontally connected between the input pipe 100 and the second communication pipe 300 along the Y-axis direction.

[0083] The concrete pouring equipment is started to pour the concrete through the input pipe 100, the first communication pipe 200, the second communication pipe 300, the output pipe 400 and the output hose 500 in the area near the tank wall opposite to the temporary door 20. During the pouring construction, the concrete pouring construction sequence can be from the area near the tank wall opposite to the temporary door 20 to the temporary door 20. During the pouring process, the pouring direction is controlled by adjusting the length of the input pipe 100 and rotating the output pipe 400. And the input pipe 100 on both sides can be alternately poured step by step.

[0084] For example, during the process of pouring from the area near the tank wall opposite to the temporary door 20 to the temporary door 20, the construction sequence of the workers can be as follows:

[0085] As shown in Figure 3 After the area A1 is poured, the first communication pipe 200 is reconnected with the second end of the input pipe 100, so that the first communication pipe 200 can pour the area B1 through the second communication pipe 300 and the output pipe 400. When the area B1 is poured, the length of the input pipe 100 is adjusted to pour the area B2. Then, the first communication pipe 200 is reconnected with the second end of the input pipe 100, so that the first communication pipe 200 can pour the area A2 through the second communication pipe 300 and the output pipe 400, and so on. That is, the construction personnel can pour according to the sequence of A1→B1→B2→A2→A3→B3, which can be seen from the direction of the dashed arrow in Figure 3 .

[0086] It can be understood that in other embodiments, as exemplified in Figure 3 , the construction personnel can also pour according to the sequence of A1→A2→A3→B1→B2→B3.

[0087] Alternatively, in other embodiments, the construction device can be configured with two first communication pipes 200, and two second communication pipes 300, two output pipes 400 and two output hoses 500. Meanwhile, the second elbow 52 can be a T-shaped three-way elbow. One interface of the T-shaped three-way elbow is connected with the second end of the input pipe 100, and the two first communication pipes 200 are connected with the other two interfaces of the T-shaped three-way elbow respectively, so that the two first communication pipes 200 can extend to the two side areas of the input pipe 100 respectively. Then the two second communication pipes 300, the two output pipes 400 and the two output hoses 500 are connected with the two first communication pipes 200 in sequence respectively. Therefore, as shown in the example, the construction personnel can also perform the pouring construction in the order of A1, B1→A2, B2→A3, B3. Figure 3

[0088] In addition, during the pouring construction, the construction personnel can transport the concrete to the dead angle where the pouring is not in place by using a small handcart or a square shovel, and then level the concrete.

[0089] The construction device of the embodiments of the application has the advantages of simple structure, convenient installation and disassembly, convenient construction, and effectively reducing the labor intensity. During the construction process, the concrete pouring construction of most areas in the tank can be completed by adjusting the length of the input pipe and rotating the output pipe, which reduces the work load of transporting the concrete from the middle of the storage tank to the periphery of the storage tank for leveling, avoids the damage of the small transport bucket to the bottom glass brick, and reduces the labor intensity of the workers in the concrete leveling layer construction.

[0090] The construction device of the embodiments of the application can effectively avoid the damage of the transport bucket to the bottom foam glass brick insulation layer during the transportation of the concrete to the periphery of the storage tank, ensure the insulation performance of the bottom insulation layer, and reduce the labor intensity of the workers and the labor cost of the construction.

[0091] The above embodiments are only exemplary descriptions of the structures, and the structures in the embodiments are not fixedly combined structures. In the absence of structural conflicts, the structures in the multiple embodiments can be used in any combination.

[0092] Although the application has been described with reference to several exemplary embodiments, it will be understood that the terms used are illustrative and not restrictive. Since the application can be embodied in many different forms without departing from the spirit or essential characteristics thereof, it should be understood that the above-described embodiments are not limited to any of the aforementioned details, but rather should be construed broadly within the spirit and scope of the appended claims, and therefore all changes and modifications that fall within the metes and bounds of the claims, or equivalents of such metes and bounds, are intended to be embraced by the claims.​
