Description

Technical Field

[0001] The invention relates to the field of assembled granary construction, and in particular to an assembled shallow round silo roof hoisting system and a silo roof hoisting method. Background Art

[0002] At present, there are various forms of storage structures in my country. Among them, the shallow circular silo is an important type of reinforced concrete. It has become a widely used warehouse type in recent years due to its large storage capacity, small footprint, large effective volume inside the silo, good airtightness, clear structural force, and good seismic performance.

[0003] Shallow round silos include silo walls and silo roofs. Silo wall construction generally adopts the relatively mature slipform construction process. Silo roof structures have the structural characteristics of large spans and heavy self-weight. They are mostly supported by full-house scaffolding and cast-in-place construction methods. This method has many problems in practical applications: the use of a large number of templates and scaffoldings leads to low equipment turnover efficiency, long silo roof construction cycle and serious material waste. The cone shell angle of the silo roof structure is large, the fluidity of the concrete makes pouring and vibration difficult, and the pouring density is difficult to ensure. The waterproof layer and the structural layer are prone to cracking and slipping under the action of their own weight, resulting in widespread leakage of the silo roof structure. The poor waterproof effect of the structure has become a common problem of this type of storage structure. In addition, open-air operations and high-altitude operations on site also increase the safety hazards of construction personnel, and the construction process is greatly affected by natural factors.

[0004] Prefabricated concrete structures meet the requirements of the country's supply-side structural reform and the development of new urbanization. Compared with traditional building structures, they have many advantages. They can be industrialized in factories to ensure the quality of the structure. They can be directly installed on the construction site, which is convenient and fast. Compared with the on-site cast-in-place silo roof, they can shorten the construction period.

[0005] Due to the conical mechanical model of the silo roof, it is a stable system composed of an upper ring beam, a fan-shaped prefabricated panel and a lower ring beam. The lower ring beam is fixed on the silo wall, and the upper ring beam is smaller and is located above the center of the silo. Workers lack a construction platform and often need multiple cranes and scaffolding to complete the installation of the silo roof, which is inefficient and unsafe. Summary of the invention

[0047] In order to facilitate the understanding of the present invention, the present invention is described in more detail below in conjunction with the accompanying drawings and specific embodiments. Preferred embodiments of the present invention are provided in the accompanying drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0048] It should be noted that, unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0049] Embodiment 1 of the present invention is a prefabricated shallow round silo roof hoisting system. Figures 1 to 20As shown: the assembled shallow circular silo includes a silo wall 3-1 and a silo roof. After the silo wall is manufactured, the silo roof is installed. The silo roof includes an upper ring beam, a plurality of fan-shaped prefabricated panels and a lower ring beam fixed to the upper end of the silo wall. In this embodiment, there are 16 fan-shaped prefabricated panels, and the 16 fan-shaped prefabricated panels form a pair of two. Therefore, there are 8 pairs of fan-shaped prefabricated panels. The two fan-shaped prefabricated panels in each pair of fan-shaped prefabricated panels are arranged 180 degrees symmetrically and named according to the installation order. From first to last, the 8 pairs of fan-shaped prefabricated panels are respectively the first pair of fan-shaped prefabricated panels 3-3-1, the second pair of fan-shaped prefabricated panels 3-3-2, the third pair of fan-shaped prefabricated panels 3-3-3, the fourth pair of fan-shaped prefabricated panels 3-3-4, the fifth pair of fan-shaped prefabricated panels 3-3-5, the sixth pair of fan-shaped prefabricated panels 3-3-6, the seventh pair of fan-shaped prefabricated panels 3-3-7 and the eighth pair of fan-shaped prefabricated panels 3-3-8.

[0050] The silo top hoisting system includes a precast concrete support 1-1, which is buried in the center of the silo wall when in use. The circular silo top hoisting system also includes a tower column 1-2 fixed to the upper end of the precast concrete support when in use. The tower column is composed of multiple standard sections 1-8 that are detachably connected in sequence along the up and down directions. Just like the columns of a tower crane, the tower column can increase or decrease standard sections as needed. When in use, the tower column is inserted into the inner hole of the upper ring beam.

[0051] The upper end of the tower column is rotatably mounted with a boom bracket through a rotating bearing 1-7, a cab 1-6 is arranged on the boom bracket, and the boom bracket is driven to rotate by a boom driving mechanism.

[0052] A symmetrically arranged first boom 2-1-1 and a second boom 2-1-2 are fixed on the boom bracket. The first boom and the second boom are arranged in a straight line. The first boom and the second boom serve as counterweights for each other, ensuring that the tower column is subjected to as little roll torque as possible. In order to improve the stability of the first boom 2-1-1 and the second boom 2-1-2, and to facilitate the driving of the first boom, the second boom and the boom bracket to rotate, in the present invention, the assembled shallow round warehouse roof hoisting system also includes an annular guide rail 2-11 for fixing to the upper end of the lower ring beam, the cross-sectional shape of the annular guide rail is a U-shape with an opening facing upward, a support device is provided between the bottom of the first boom and the second boom and the annular guide rail, and the support device includes a first support rod 2-6-1 and a second support rod 2-6-2 arranged in an eight-shaped pattern, and the bottom of the first support rod 2-6-1 and the second support rod 2-6-2 is provided with a support rod walking wheel that cooperates with the annular guide rail for guiding movement.

[0053] The upper ends of the first support rod and the second support rod are hingedly connected to the two sides of the corresponding boom through fixing pins 2-7, and the boom driving mechanism includes a running wheel driving motor for driving the running wheels of the corresponding support rods to rotate.

[0054] The first boom and the second boom are provided with a trolley track 4 extending along the length direction of the corresponding boom, the trolley track is made of a pair of I-beams arranged left and right, and the trolley tracks of the first boom and the second boom are both guided and movablely assembled with a first crane 2-2-1 and a second crane 2-2-3 capable of independent movement, that is, the guided and movable assembly on the trolley track of the first boom has two cranes, which are respectively referred to as the first crane and the second crane, and the guided and movable assembly on the trolley track of the second boom has two cranes, which are respectively referred to as the first crane and the second crane.

[0055] The first crane and the second crane both have track running wheels 6 that match the trolley track. The first crane and the second crane are respectively provided with a crane power system that is transmission-connected to the corresponding track running wheels, and the crane power system includes a reduction motor, and each crane is driven by the crane power system to move and walk independently.

[0056] The first crane is provided with a first crane rope 2-3-1 which can be raised and lowered, and the second crane is provided with a second crane rope 2-2-3 which can be raised and lowered. The first crane rope and the second crane rope can be raised and lowered independently of each other. The first crane rope includes a first crane rope on the left and a first crane rope on the right; the second crane rope includes a second crane rope on the left and a second crane rope on the right.

[0057] The first crane includes a first rope drum for driving the lifting of the first crane rope on the left and the first crane rope on the right, and the first rope drum is driven by a corresponding rope drum reduction motor; the second crane includes a second rope drum for driving the lifting of the second crane rope on the left and the second crane rope on the right, and the second rope drum is driven by a corresponding rope drum reduction motor.

[0058] The first crane is provided with a first rope pulley for the first crane rope to be wound around and reversed, and the second crane is provided with a second rope pulley for the second crane rope to be wound around and reversed.

[0059] In order to prevent the first support rod 2-6-1 and the second support rod 2-6-2 from blocking the movement of the first hoisting trolley, the second hoisting trolley and the corresponding fan-shaped prefabricated panels, the bottom of the first boom and the second boom is provided with an extended cross bar 2-2-5 extending in the left and right directions, and the upper ends of the first boom and the second boom are hingedly connected to the two ends of the extended cross bar 2-2-5 through fixing pins 2-7. There is a passing space between the upper ends of the first support rod and the second support rod for the hoisting trolley to pass through.

[0060] In this embodiment, in order to improve the stability of the tower column, a tower column stabilizing support rod 3-2 is arranged between the tower column and the warehouse wall. Specifically, a warehouse wall hinge seat is fixed on the warehouse wall. One end of the tower column stabilizing support rod is hingedly connected to the warehouse wall hinge seat, and the other end is hingedly connected to the corresponding standard section on the tower column.

[0061] An upper column 2-4 is arranged at the upper end of the tower column, and a fixing rope 2-5 is arranged between the upper column 2-4 and the two ends of the corresponding boom. By pulling the boom with the fixing rope, the first boom and the second boom are made more stable during operation.

[0062] During construction, the top surface of the precast concrete support 1-1 is buried flush with the ground, the upper ring beam bracket 1-4 is placed on the precast concrete support, the upper ring beam is placed on the upper ring beam bracket, and then the standard sections of the tower column are built up one by one, and then the first boom, the second boom, the eight-shaped support rod, the upper column and other entire tower frames are assembled. This process is somewhat similar to the assembly process of the tower crane in the prior art.

[0063] Then lower the first hoist rope 2-3-1 of the two first hoists, and the lower end of the first hoist rope 2-3-1 is connected to the upper ring beam bracket 1-4. Figure 3 As shown, the upper ring beam 1-3 is lifted to a specified height by the upper ring beam bracket. Figure 5 As shown, a support fixing clip 1-5 is then provided at the bottom of the upper ring beam bracket 1-4, and the support fixing clip 1-5 is fixed to the tower column by bolts, and the upper ring beam bracket 1-4 and the upper ring beam are supported by the support fixing clip 1-5, so that the connection between the first crane rope 2-3-1 and the upper ring beam bracket can be disconnected, and the first crane can be moved to the outside of the warehouse wall, the first crane rope of the first crane is lowered, and the second crane rope of the second crane is lowered, and the fan-shaped prefabricated panels in the first pair of fan-shaped prefabricated panels are lifted by the cooperation of the first crane and the second crane, as shown in FIG. Figure 6 The movement of the first and second cranes, the retracting and releasing of the ropes, and the control of the travel wheel drive motors are all completed in the cab.

[0064] Then the first and second cranes of the two groups will lift the corresponding fan-shaped prefabricated panels to the high position respectively. Fig. 9 Then, the first crane and the second crane move toward the tower column, thereby lifting the fan-shaped prefabricated panel to the upper side of the upper ring beam and the lower ring beam. Since the first crane and the second crane are lifted and lowered independently of each other, the second crane can first lower the bottom of the fan-shaped prefabricated panel to the lower ring beam, and then the first crane can lower the upper end of the fan-shaped prefabricated panel to the upper ring beam, as shown in FIG. Fig.10 After the fan-shaped prefabricated panel is put into place, the fan-shaped prefabricated panel is connected to the upper ring beam 1-3 by the upper bolts, and the fan-shaped prefabricated panel is connected to the lower ring beam 2-10 by the lower bolts 8, as shown in FIG. Fig.13 As shown, this completes the installation of the first pair of fan-shaped prefabricated panels.

[0065] Subsequently, the second pair of fan-shaped prefabricated panels are installed. The specific process is that the walking wheel driving motor drives the supporting rod walking wheel to rotate along the annular guide rail 2-11, and the first supporting rod and the second supporting rod drive the first hanging arm and the second hanging arm to rotate 90 degrees around the tower column axis, changing the orientation of the first hanging arm and the second hanging arm. Fig.14 As shown, the second pair of fan-shaped prefabricated panels can be hoisted subsequently. After the second pair of fan-shaped prefabricated panels are hoisted, the first and second hoisting arms are rotated again to hoist the next pair of fan-shaped prefabricated panels until eight pairs, i.e., all fan-shaped prefabricated panels are hoisted. Then, the assembled shallow round warehouse roof hoisting system is dismantled. Fig.19 shown.

[0066] The present invention adopts a stable boom device, which can effectively solve the problem of lack of construction platform for workers during construction, replace high-altitude operations, and increase construction safety; the first boom and the second boom are driven to rotate by the support rod, which is beneficial to reduce the demand for rotational torque; only two cranes are required on each boom to complete the lifting of all fan-shaped prefabricated panels, and the overall structure is simple.

[0067] In other embodiments of the present invention: the movement of the first crane and the second crane can also be achieved by other forms, such as a setting similar to a moving vehicle on a tower crane, in which a reel is set on the first crane and the second crane, a wire rope is wound on the reel, and a wire rope retracting device for retracting and releasing the wire rope is set on the boom bracket, and the movement of the crane along the boom is achieved by retracting and releasing the wire rope; the boom driving mechanism can also be directly arranged between the tower column and the boom bracket, for example, the boom driving mechanism includes a driving motor fixed on the tower column, an outer gear ring is fixed on the boom bracket, and a transmission gear meshing with the outer gear ring is provided at the power output end of the driving motor.

[0068] Example 2 of the assembled shallow round silo roof hoisting system Fig.21 As shown: Embodiment 2 is different from Embodiment 1 in that the annular guide rail 2-11 is made of I-beam, which includes an upper end plate 10, a lower end plate 11 and an intermediate web connected between the upper end plate and the lower end plate, and the support rod running wheel 5 is rolled and matched with the inner top surface of the lower end plate of the I-beam, and the support rod running wheel 5 is located between the upper end plate and the lower end plate, and the running wheel driving motor 9 drives the support rod running wheel 5 to rotate. The advantage of this arrangement is that when there is a heavy object on one of the booms, for example, there is a heavy object on the first boom, and there is no heavy object on the second boom, the support rod running wheel corresponding to the second boom will be rolled and matched with the upper end plate of the annular guide rail to prevent the first boom from tipping over due to the heavy object.

[0069] Silo roof hoisting method Figures 1 to 21 As shown, the method comprises the following steps:

[0070] In the first step, the first hoisting vehicle on the first hoisting arm and the second hoisting arm of the silo roof hoisting system is used to hoist the upper ring beam from bottom to top to a specified height, and the upper ring beam is positioned on the tower column. The specific structure of the silo roof hoisting system is the same as the silo roof hoisting system described in the above-mentioned embodiments of the silo roof hoisting system for assembled circular silos, and will not be described in detail here.

[0071] The second step is to dismantle the connection between the first crane and the upper ring beam, and the first crane and the second crane on the first boom cooperate; the first crane and the second crane on the second boom cooperate to respectively lift the first pair of fan-shaped prefabricated panels from bottom to top on the outer side of the warehouse wall, and the two fan-shaped prefabricated panels of the first pair of fan-shaped prefabricated panels are arranged opposite to each other, and then the corresponding crane moves the corresponding fan-shaped prefabricated panels along the corresponding boom to the upper side of the upper ring beam and the lower ring beam, and lowers the fan-shaped prefabricated panels, thereby completing the connection between the first pair of fan-shaped prefabricated panels and the upper ring beam and the lower ring beam;

[0072] In the third step, the boom driving mechanism drives the boom bracket to rotate, and the first boom and the second boom rotate away from the position of the first pair of fan-shaped prefabricated panels, and the second step is repeated to complete the hoisting of the second pair of fan-shaped prefabricated panels;

[0073] Step 4: Repeat step 3 until the lifting of the 8th pair of fan-shaped precast panels is completed.

[0074] In other embodiments of the present invention, according to the diameter of the shallow circular silo roof, the number of pairs of fan-shaped prefabricated panels can also be 5 pairs, 6 pairs or other pairs. Of course, the number of fan-shaped prefabricated panels can also be an odd number. In this case, only one fan-shaped prefabricated panel needs to be hoisted at the end.

[0075] In the third step, the two fan-shaped prefabricated panels of the second pair of fan-shaped prefabricated panels are respectively located in the middle of the two fan-shaped prefabricated panels of the first pair of fan-shaped prefabricated panels. This is more conducive to establishing a stable warehouse roof structure system as soon as possible.
