Description

Technical Field

[0001] The utility model belongs to the technical field of heliostat installation, and particularly relates to a hoisting tool for a heliostat mirror body. Background Art

[0002] As a clean and renewable energy source, solar energy has been increasingly applied. In particular, solar thermal power generation technology is a new solar energy utilization technology following photovoltaic power generation technology. Among them, tower solar thermal power generation technology has the advantage of energy storage and peak shaving, and the solar thermal power generation industry has developed rapidly in recent years.

[0003] The function of the heliostat in tower solar thermal power generation is to concentrate sunlight on the receiver. A large number of heliostats are required in each mirror field to reflect enough heat to the receiver. When installing the heliostat mirror body, special tools are usually connected to both ends of the main beam of the heliostat respectively, and then the sling is connected to the special tools at both ends of the main beam of the heliostat, and the hook of the crane is connected to the sling, so that the crane can lift the heliostat mirror body through the sling, and then move it to the installation position. After the heliostat mirror body is installed on the heliostat, the special tool is removed. Then, since the sling is inclined during the hoisting process, this causes the sling to exert a pulling force on the special tool. The vertical component of this pulling force is used to balance the gravity of the heliostat mirror body, while the horizontal component will act on the main beam of the heliostat and be borne by the main beam of the heliostat, which makes the main beam of the heliostat at risk of bending.

[0025] Due to the adoption of the above technical solutions, the present utility model has the following advantages and positive effects compared with the prior art:

[0026] 1. When using the hoisting tooling for the heliostat mirror body provided by the present utility model to hoist the heliostat mirror body by using a hoisting device, the hoisting device is connected to the hoisting structure on the stress beam. Since all the connecting pieces cooperate with each other, an upward force is applied to the heliostat main beam when the stress beam is hoisted by the hoisting device. Therefore, the heliostat main beam is not subjected to an axial force, and there is no risk of bending of the heliostat main beam. If the pulling force applied by the hoisting device to the hoisting structure has a horizontal component force, the horizontal component force is borne by the stress beam.

[0027] 2. The lifting device of the present utility model realizes fine adjustment of the position of the heliostat mirror body by setting the first connecting ear, the second connecting ear and the third connecting ear, and setting the thickness of the third connecting ear to be less than the gap between the first connecting ear and the third connecting ear when assembling the heliostat mirror body with external components after lifting the heliostat mirror body; specifically, the distance between the first connecting ear and the second connecting ear is greater than the thickness of the third connecting ear, a first connecting hole is provided on the first connecting ear, a second connecting hole is provided on the second connecting ear, and a third connecting hole is provided on the third connecting ear. The insertion rod horizontally penetrates the first connecting hole, the second connecting hole and the third connecting hole to realize the suspension connection of the second middle part to the first middle part. With the apertures of the first connecting hole and the second connecting hole being adapted to the diameter of the insertion rod and the aperture of the third connecting hole being greater than the diameter of the insertion rod, it is thus possible to allow fine adjustment of the position of the heliostat mirror body by means of the aforementioned small-range movement, thereby making the installation and debugging of the heliostat mirror body more convenient.

[0028] 3. When the lifting device in the present utility model lifts the heliostat mirror body by the heliostat mirror body, the force application direction of the crane hook of the lifting device is generally within the vertical plane passing through the axis of the force-bearing beam or near the vertical plane passing through the axis of the force-bearing beam. For a heliostat mirror body with the center of gravity of the heliostat mirror body located on one side of the vertical plane passing through the axis of the main beam of the heliostat, in some preferred embodiments, by setting the force-bearing beam not directly above the main beam of the heliostat but towards the direction of the center of gravity of the heliostat mirror body, the lifting equipment can lift the heliostat mirror body as smoothly as possible; more preferably, the force-bearing beam can be set directly above the center of gravity of the whole of the heliostat mirror body and the two connecting pieces (that is, the vertical plane passing through the axis of the force-bearing beam is the force-bearing beam plane, and the center of gravity of the whole of the two connecting pieces and the heliostat mirror body passes through the force-bearing beam plane).

[0038] Embodiment 1

[0039] Refer to Figures 1 to 4 , this embodiment provides a heliostat mirror body lifting tooling 10, including a stress beam 11 and two connecting pieces. A hoisting structure is provided on the stress beam 11, and the hoisting structure is used to connect with a hoisting device. The two connecting pieces are respectively connected to the stress beam 11, and the connection between the two connecting pieces and the stress beam 11 is configured such that when the stress beam 11 is lifted by the hoisting device, under the action of the two connecting pieces, each point on the axis of the heliostat main beam is located at the same height (each point on the axis of the heliostat main beam is each point on the axis of the heliostat main beam, that is, at this time, the axis of the heliostat main beam is in a horizontal state). Among them, the two connecting pieces are respectively detachably connected to the two ends of the heliostat main beam. One of the two connecting pieces is arranged at the first end of the heliostat main beam, and the other is arranged at the second end of the heliostat main beam. All the connecting pieces cooperate with each other to apply an upward force to the heliostat main beam when the stress beam 11 is lifted by the hoisting device.

[0040] When using the heliostat mirror body lifting tooling 10 of this embodiment to lift the heliostat mirror body 20, the lifting equipment is connected to the lifting structure on the stress beam 11. Since all the connecting parts cooperate with each other, when the stress beam 11 is lifted by the lifting equipment, only an upward force is exerted on the main beam of the heliostat. Therefore, the main beam of the heliostat is not subjected to axial force, and there is no risk of the main beam of the heliostat bending. If the pulling force applied by the lifting equipment to the lifting structure has a horizontal component force, the horizontal component force is borne by the stress beam 11.

[0041] The heliostat mirror body lifting tooling 10 of this embodiment will be further described below.

[0042] The stress beam 11 is mainly used to bear the horizontal component force of the force exerted by the lifting equipment when lifting the heliostat mirror body 20. Therefore, the stress beam 11 is preferably arranged horizontally, parallel to the main beam of the heliostat, and located above the main beam of the heliostat.

[0043] The connecting parts include a hanging bracket 15 and a connecting seat. In each connecting part, the hanging bracket 15 is connected to the stress beam 11 through at least one intermediate structure. The intermediate structure includes a first intermediate part 12 and a second intermediate part 13. The first intermediate part 12 is fixedly connected to the stress beam 11. One end of the second intermediate part 13 is detachably connected to the first intermediate part 12, and the other end of the second intermediate part 13 is fixedly connected to the hanging bracket 15. One end of the connecting seat is detachably connected to the hanging bracket 15, and the other end is sleeved on or extends into the corresponding end of the main beam of the heliostat.

[0044] The vertical plane passing through the axis of the stress beam 11 is called the stress beam plane. Preferably, in this embodiment, each hanging bracket 15 is respectively provided with two intermediate structures, and these two intermediate structures are distributed on both sides of the stress beam plane.

[0045] The first intermediate part is fixedly or detachably connected to the second intermediate part through a connecting structure.

[0046] Preferably, the first intermediate part 12 and the second intermediate part 13 are connected through a suspension structure. The suspension structure includes a first connecting ear 14 and a second connecting ear provided on the first intermediate part 12, a third connecting ear provided on the second intermediate part 13, and an insertion rod 19. The first connecting ear 14 and the second connecting ear are arranged side by side at intervals. The third connecting ear is located between the first connecting ear 14 and the second connecting ear. The first connecting ear 14 is provided with a first connecting hole, the second connecting ear is provided with a second connecting hole, the third connecting ear is provided with a third connecting hole, and the insertion rod 19 horizontally penetrates through the first connecting hole, the second connecting hole and the third connecting hole to realize the suspension connection of the second intermediate part 13 to the first intermediate part 12.

[0047] Specifically, as shown in Figure 3 and Figure 4As shown in the figure, mounting parts corresponding to the hanging brackets 15 are welded to both ends of the stressed beam 11. The mounting parts are square tube structures (in other embodiments, the mounting parts can also adopt other structures). The side of the square tube structure of the mounting part is welded to the stressed beam 11; the upper ends of the two first middle parts 12 are respectively welded and connected to both ends of the mounting part. Further, between the mounting part and the stressed beam 11, and between the mounting part and the two first middle parts 12, welding reinforcement parts can be used to increase the connection stability.

[0048] The hanging brackets 15 can also adopt square tube structures (in other embodiments, the mounting parts can also adopt other structures). The side of the square tube structure of the hanging brackets 15 is used to connect to the connecting seat; the lower ends of the two second middle parts 13 are respectively welded and connected to both ends of the hanging brackets 15. Further, between the hanging brackets 15 and the two second middle parts 13, welding reinforcement parts can be used to enhance the connection stability.

[0049] The two first middle parts 12 and the two second middle parts 13 correspond one by one, and they are respectively fixedly or detachably connected through a connection structure. Preferably, the connection structure is a suspension structure connection, that is, one of the first middle parts 12 and the corresponding second middle part 13 are connected through a suspension structure, and the other first middle part 12 and the corresponding second middle part 13 are connected through another suspension structure.

[0050] Specifically, in one of the first middle parts 12, the corresponding second middle part 13, and the suspension structure, the first connecting ear 14 and the second connecting ear are welded side by side and spaced apart on the outside of the first middle part 12 (that is, on the side opposite to the other first middle part 12 corresponding to the same hanging bracket 15), and the third connecting ear is a part of the top of the second middle part 13. The third connecting ear is located between the first connecting ear 14 and the second connecting ear, that is, the top of the second middle part 13 extends into the space between the first connecting ear 14 and the second connecting ear. The first connecting hole on the first connecting ear 14, the second connecting hole on the second connecting ear, and the third connecting hole on the third connecting ear cooperate with each other to form an installation channel. The direction of the installation channel is parallel to the axial direction of the heliostat main beam; the insertion rod 19 passes through the installation channel, so that the second middle part 13 is suspended on the first middle part 12 through the insertion rod 19. Through the design of the first connecting hole, the second connecting hole, and the third connecting hole, the insertion rod 19 can be parallel to the heliostat main beam.

[0051] Of course, in other embodiments, there can be other choices for the specific structures of the first middle part 12, the second middle part 13, and the suspension structure. The structure shown in this embodiment is only a preferred structure.

[0052] The hoisting structure on the load-bearing beam 11 is specifically designed according to the hoisting equipment, and there is no limitation here. For example, it can be a lifting ring fixed above the middle of the load-bearing beam 11, and so on. In this embodiment, there are two hoisting structures on the load-bearing beam 11, and the two hoisting structures are respectively arranged at both ends of the load-bearing beam 11. Specifically, the two hoisting structures respectively correspond to the two hanging brackets 15. The hoisting structure is a lifting hole 12-1 arranged at the top of the two first middle parts 12 corresponding to the corresponding hanging brackets 15. The heliostat mirror body hoisting tool 10 of this embodiment has four first middle parts 12, and lifting holes 12-1 are arranged at the tops of the four first middle parts 12. When hoisting, one ends of four equal-length sling straps are respectively connected to the lifting holes 12-1 at the tops of the four first middle parts 12, and the other ends of the four equal-length sling straps are connected to the crane hook of the hoisting equipment. After hoisting, the sling straps apply an inclined upward pulling force to the first middle part 12, and the horizontal component of this pulling force acts on the load-bearing beam 11, so as to ensure that the heliostat mirror body 20 itself is not stressed in the horizontal direction.

[0053] Preferably, there is a symmetry plane perpendicular to the axial direction of the load-bearing beam 11. The two connecting members are symmetric about the symmetry plane, and the corresponding intermediate structures of the two connecting members are symmetric about the symmetry plane (that is, the two intermediate structures at one end of the load-bearing beam 11 and the two intermediate structures at the other end of the load-bearing beam 11 are symmetric about the symmetry plane), and the two hoisting structures are symmetric about the symmetry plane (that is, the two lifting holes 12-1 on the two first middle parts 12 at one end of the load-bearing beam 11 and the two lifting holes 12-1 on the two first middle parts 12 at the other end of the load-bearing beam 11 are symmetric about the symmetry plane).

[0054] When the hoisting device hoists the heliostat mirror body by the heliostat mirror body, the force-bearing direction of the crane hook of the hoisting device is generally in the vertical plane passing through the axis of the load-bearing beam (that is, the load-bearing beam plane) or near the vertical plane passing through the axis of the load-bearing beam. For example, in this embodiment, the crane hook of the hoisting device is connected to the hoisting structure through four sling straps to hoist the heliostat mirror body. Ideally, the force-bearing direction of the crane hook is located in the vertical plane passing through the axis of the load-bearing beam. However, during actual operation, there may be a slight deviation, so that the force-bearing direction of the crane hook is located near the vertical plane passing through the axis of the load-bearing beam.

[0055] The vertical plane passing through the axis of the main beam of the heliostat is called the main beam plane. The center of gravity of the heliostat mirror body 20 is usually located on one side of the main beam plane. For such a situation, it is preferably to make the axis of the load-bearing beam 11 and the center of gravity of the heliostat mirror body be on the same side of the main beam plane, that is, the load-bearing beam 11 is not arranged directly above the main beam of the heliostat, but is arranged towards the direction of the center of gravity of the heliostat mirror body, so that the hoisting equipment can hoist the heliostat mirror body as smoothly as possible.

[0056] Preferably, the stress beam 11 can be arranged directly above the center of gravity of the overall heliostat mirror body and all connecting members. The center of gravity of all connecting members and the heliostat mirror body passes through the stress beam surface. Further, in two intermediate structures corresponding to the same connecting member, the two suspension structures are symmetric about the stress beam surface. Such a design enables the center of gravity of the overall heliostat mirror body 20 and the heliostat mirror body lifting tooling 10 of this embodiment to be consistent with the stress direction of the crane hook after being lifted by the lifting device, thus ensuring the stable lifting of the heliostat mirror body 20 and preventing the heliostat mirror surface from being easily bumped during the lifting process.

[0057] The connection mode between the connection seat and the main beam of the heliostat can be that the connection seat is sleeved on the end of the main beam of the heliostat, or the connection seat extends into the pipe orifice at the end of the main beam of the heliostat. Since support beams for installing the mirror surface are usually arranged on the outer side wall of the main beam of the heliostat, in this embodiment, it is preferably to adopt the way that the connection seat extends into the pipe orifice at the end of the main beam of the heliostat. Specifically, the connection seat includes a connecting rod 16 and at least two support discs 17. The support discs 17 are sleeved on the connecting rod 16 and connected to the connecting rod 16 (the connection mode can adopt welding connection, etc.), and all the support discs 17 are arranged at intervals along the axial direction of the connecting rod 16. One end of the connecting rod 16 is fixedly connected to the corresponding hanging bracket 15, and the other end extends into the pipe orifice at the corresponding end of the main beam of the heliostat. All the support discs 17 on the connecting rod 16 are located inside the pipe body of the main beam of the heliostat, and the outer diameter of the support disc 17 is adapted to the inner diameter of the pipe body of the main beam of the heliostat. The design that the outer diameter of the support disc 17 is adapted to the inner diameter of the pipe body of the main beam of the heliostat can reduce or avoid the shaking of the connecting rod 16 in the pipe body of the main beam of the heliostat, thereby improving the stability of lifting. Setting multiple support discs 17 can increase the contact area between the connection seat and the inner wall surface of the pipe body of the main beam of the heliostat, further improving the stability of lifting. Preferably, the connecting rod 16 is located at the center of the support disc 17, that is, the axis of the connecting rod 16 coincides with the axis of the support disc 17. In this way, the connecting rod 16 can be in the central position in the pipe body of the main beam of the heliostat. Of course, in other embodiments, the connection seat can also have other structural forms, such as the connection seat is directly a cylinder with an outer diameter adapted to the inner diameter of the pipe body of the main beam of the heliostat, etc. The design of the connecting rod 16 and the support disc 17 adopted in this embodiment can save materials compared with the design of the cylinder.

[0058] A positioning hole 16-1 corresponding to the anti-rotation hole on the main beam of the heliostat is provided on the connecting rod 16. After the connection seat extends into the pipe body of the main beam of the heliostat, by inserting a positioning pin 30 into the anti-rotation hole on the main beam of the heliostat and the positioning hole 16-1 on the connecting rod 16, the rotation of the connection seat in the pipe body of the main beam of the heliostat and the movement in the axial direction of the main beam of the heliostat can be prevented.

[0059] There are various ways to connect the connecting rod 16 to the second intermediate part 13, and no specific restrictions are imposed. In this embodiment, one end of the connecting rod 16 for fixedly connecting to the second intermediate part 13 is welded to a mounting plate 18, and the mounting plate 18 is fixedly connected to the second intermediate part 13 by bolts, thereby realizing that one end of the connecting rod 16 is fixedly connected to the side of the square tube structure of the second intermediate part 13; further, a pin can be provided. A first hole corresponding to the pin is provided on the whole of the welded connecting rod 16 and the mounting plate 18, and a second hole corresponding to the pin is also provided on the second intermediate part 13. When the connecting rod 16 is fixedly connected to the second intermediate part 13, first use the pin to pass through the second hole and the first hole for positioning, and then fasten the mounting plate 18 and the second intermediate part 13 with bolts.

[0060] In actual application, the second intermediate part 13 and the connecting member are pre-installed on the heliostat main beam in advance. The pre-installation mainly includes two parts, namely the connection between the connection seat and the heliostat main beam, and the connection between the connection seat and the hanging bracket 15 (at this time, the second intermediate part 13 has been pre-welded on the hanging bracket 15), and there is no requirement for the sequence of the two. At the mirror field, that is, the hoisting site, first use the insertion rod 19 to connect the first intermediate part 12 and the second intermediate part 13 to complete the assembly of the entire heliostat mirror body hoisting tooling 10 of this embodiment, and then use a sling to connect the heliostat mirror body hoisting tooling 10 to the crane hook of the hoisting equipment, and finally use the hoisting equipment for hoisting.

[0061] For the heliostat mirror body hoisting tooling 10 provided in this embodiment, the connecting member (including the second intermediate part 13 already welded on the hanging bracket 15) can be pre-installed on the heliostat main beam in the workshop, and the first intermediate part 12 can also be pre-welded on the stress beam 11. At the mirror field, only by quickly connecting the first intermediate part 12 and the second intermediate part 13 through the insertion rod 19 can the hoisting work be carried out. Therefore, by using the heliostat mirror body hoisting tooling 10 provided in this embodiment, the installation time at the mirror field can be saved, and the effect of high hoisting efficiency can be achieved.

[0062] Embodiment 2

[0063] This embodiment provides a heliostat mirror body hoisting tooling 10 based on Embodiment 1. The heliostat mirror body hoisting tooling 10 in this embodiment optimizes the design of the suspension structure on the basis of Embodiment 1.

[0064] In this embodiment, the distance between the first connecting ear 14 and the second connecting ear is greater than the thickness of the third connecting ear; both the first connecting hole and the second connecting hole are round holes, and the third connecting hole is an oval hole (or in other embodiments, the third connecting hole can also be a round hole). Among them, the diameters of the first connecting hole and the second connecting hole are adapted to the diameter of the insertion rod 19, and the diameter of the third connecting hole is greater than the diameter of the insertion rod 19 (where the diameter of the oval hole is the width of the oval hole).

[0065] The aperture of the third connection hole is larger than that of the insertion rod 19, and the design of the waist-shaped hole is for the convenience of installing the insertion rod 19. At the same time, the second middle part 13 can move a small range along the axial direction of the insertion rod 19 and swing a small range along the radial direction of the insertion rod 19 relative to the first middle part 12. Since the movable range along the axial and radial directions of the insertion rod 19 is small, it can ensure the stable lifting of the heliostat mirror body 20. At the same time, when the heliostat mirror body 20 is assembled with external components after being lifted, the small range of movement mentioned above can be used to finely adjust the position of the heliostat mirror body 20, so as to facilitate the assembly of the heliostat mirror body 20 with external components (for example, aligning the mounting holes on the heliostat mirror body 20 with the mounting holes on the external components).

[0066] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Even if various changes are made to the present invention, provided that these changes fall within the scope of the claims of the present invention and their equivalent technologies, they still fall within the protection scope of the present invention.
