Description

Technical Field

[0001] This utility model relates to the field of heliostat hoisting technology, specifically to a heliostat body hoisting fixture. Background Technology

[0002] Tower solar thermal power generation is a solar power technology with built-in energy storage and stable output, serving as a peak-shaving and energy storage system. Its concentrating system consists of a large heliostat array responsible for focusing solar energy. The core component of the concentrating system is the heliostat, which typically comprises the mirror body, transmission components, and support columns. Due to the large weight and area of ​​the heliostat body, and the high brittleness of the mirrors, making them prone to breakage, good stability is crucial during hoisting. Currently, heliostat installation suffers from low efficiency, high operational difficulty, and inability to install in windy conditions. Developing a convenient and stable hoisting tool to support the mirror body is an effective way to address these challenges. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a heliostat body lifting fixture that can adaptively support the back support structure of the heliostat body, thereby improving the stability and operational efficiency during the heliostat body lifting process.

[0004] This utility model provides a lifting fixture for a heliostat body, used for lifting heliostat bodies. The heliostat includes a mirror surface and a frame for supporting the mirror surface. The frame includes a main shaft and several frame units spaced apart along the axial direction of the main shaft. Each frame unit includes two support beams on both sides of the main shaft, a support fixedly mounted on the main shaft, and a secondary beam. In each frame unit, the upper part of the support is connected to the middle part of the secondary beam, one end of each support beam is connected to the lower part of the support, and the other end of each support beam is connected to the secondary beam. The lifting fixture includes a main beam, with main arms symmetrically arranged below both ends of the main beam. The arm is connected to the main beam via a swivel joint, allowing the main arm to rotate around its central axis. A main support arm is located on the side of the main arm facing the heliostat body. At the end of the main support arm away from the main arm, a main support bearing for supporting the main shaft is provided. Secondary support arms are located on both sides of the end of the main arm away from the main beam. The central axis of the secondary support arms is perpendicular to the central axis of the main support arm. Two secondary support bearings are located on the side of the secondary support arms facing the heliostat body, corresponding to the two support beams, thus restricting the rotation of the heliostat body around the central axis of the main shaft. (Heliostat body)

[0005] Preferably, the mirror body support arm has an L-shaped or L-shaped structure.

[0006] Preferably, when the lens body secondary support arm has an L-shaped structure, the lens body secondary support support portion has an I-shaped structure, and the lens body secondary support support portion is fixedly connected to the lens body secondary support arm, detachably connected, or integrally formed.

[0007] Preferably, when the lens body secondary support arm has an L-shaped structure, the lens body secondary support support portion has a plate-shaped structure or a ring-shaped structure, the lens body secondary support arm passes through or is embedded in the lens body secondary support support portion, and is rotatably connected to the lens body secondary support support portion.

[0008] Preferably, the device also includes tensioning components symmetrically arranged on both sides of the main arm. One end of the tensioning component is connected to the main arm or a main arm support rod provided on the main arm, and the other end is connected to the end of the lens body sub-support near the main arm.

[0009] Preferably, the main support of the mirror body includes two limiting components, the distance between the two limiting components being matched with the support, for accommodating the support between the two limiting components.

[0010] Preferably, the upper end face of the limiting component is provided with a groove that matches the main shaft.

[0011] Preferably, the system also includes a telescopic arm that can extend and retract along the main beam, with one end of the telescopic arm connected to the main beam and the other end connected to the main arm via the swivel joint.

[0012] Preferably, the main beam is provided with lifting lugs.

[0013] Preferably, a flexible pad is provided on the contact surface between the mirror body sub-support and the support beam.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] (1) The tooling uses the main support of the mirror body as the main force-bearing component for fixing and hoisting the mirror body, and the secondary support of the mirror body as the auxiliary force-bearing component for restricting the rotation of the mirror body. The swivel joint enables the main arm to rotate around the central axis of the main arm. By setting the secondary support of the mirror body, the rotation of the heliostat mirror body around the central axis of the main shaft is restricted, which can prevent the heliostat mirror body from deflecting or even turning over during the hoisting process, resulting in damage to the mirror body. This improves the stability of the heliostat hoisting process, achieves the smooth hoisting of the mirror body, and improves the efficiency of the hoisting operation.

[0016] (2) By setting a telescopic arm that can extend and retract along the main beam, the tooling can be used in a variety of situations and can also adapt to more styles of heliostats, thus improving the tooling's versatility.

[0017] (3) The main support of the mirror body consists of two limiting components. The two limiting components can clamp the support and restrict the movement of the mirror body in the axial direction along the main shaft, so as to improve the stability of the mirror body hoisting.

[0018] (4) By setting a flexible pad on the secondary support of the mirror body, the secondary support of the mirror body is fully fitted with the support beam, thereby improving the hoisting stability. Furthermore, by setting the secondary support of the mirror body as a plate-shaped structure or a ring-shaped structure, the secondary support of the mirror body and the support beam are in surface contact, so as to improve the hoisting stability while dispersing the force on the support beam and preventing local stress from damaging the support beam and affecting the accuracy of the mirror body.

[0019] (5) Before lifting the heliostat body, the main support and auxiliary support of the lifting fixture need to be moved to the bottom of the heliostat body to be lifted. In this way, when the lifting fixture is lifted, the main support and auxiliary support of the heliostat body can be lifted. In order to avoid interference between the auxiliary support and the heliostat body when it is moved to the bottom of the heliostat body, this utility model uses a tensioning component to connect the inner side of the auxiliary support to the main arm or the main arm support rod. When the lifting fixture is not in contact with the heliostat body, the auxiliary support can be kept horizontal under the tensioning component. This can avoid interference between the auxiliary support and the heliostat body when it is moved to the bottom of the heliostat body. At the same time, the tensioning component can also prevent the auxiliary support from rotating at will when it is not supported. Attached Figure Description

Detailed Implementation

[0027] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0028] Example 1:

[0029] Please see Figures 1-4 The illustration shows a heliostat body lifting fixture provided by an embodiment of the present invention, used for lifting heliostat bodies. The heliostat body includes a mirror J4 and a frame for supporting the mirror J4. The frame includes a main shaft J1 and several frame units spaced apart along the axial direction of the main shaft J1. Each frame unit includes two support beams J2 disposed on both sides of the main shaft J1, a support J3 fixedly disposed on the main shaft J1, and a secondary beam J5. In each frame unit, the upper part of the support J3 is connected to the middle part of the secondary beam J5, one end of each support beam J2 is connected to the lower part of the support J3, and the other end of each support beam J2 is connected to the secondary beam J5. Preferably, the main shaft J1 has a cylindrical structure.

[0030] The lifting fixture includes a main beam 1, on which lifting lugs 10 are provided for connecting lifting ropes. Main booms 4 are symmetrically arranged below both ends of the main beam 1. The main booms 4 are connected to the main beam 1 via swivel joints 3, allowing them to rotate around their central axis. The swivel joints 3 have a self-locking function. A main support arm 5 for the heliostat is located on the side of the main boom 4 facing the heliostat body. A main support support part 6 for supporting the main shaft J1 is located at the end of the main support arm 5 away from the main boom 4. Secondary support arms 7 are located on both sides of the end of the main boom 4 away from the main beam 1. The central axis of the secondary support arms 7 is perpendicular to the central axis of the main support arm 5. The secondary support arms 7 face the heliostat. Two secondary support bearing parts 8 are provided on one side of the mirror body to support the two support beams J2 respectively. The tooling uses the main support bearing part 6 as the main force-bearing component for fixing and hoisting the mirror body, and the secondary support bearing parts 8 as the auxiliary force-bearing component for restricting the rotation of the mirror body. The swivel joint 3 enables the main arm 4 to rotate around the central axis of the main arm 4. By setting the secondary support bearing parts 8, the rotation of the heliostat mirror body around the central axis of the main shaft J1 is restricted, which can prevent the heliostat mirror body from deflecting or even turning over during the hoisting process, thus preventing damage to the mirror body. This improves the stability of the heliostat during hoisting, achieves smooth hoisting of the mirror body, and improves the efficiency of the hoisting operation.

[0031] The main support 6 of the mirror body includes two limiting components. The distance between the two limiting components matches the support J3. The support J3 is accommodated between the two limiting components to restrict the movement of the mirror body in the axial direction along the main shaft J1 and prevent damage to the mirror body due to axial movement during hoisting. Preferably, the upper end face of the limiting component is provided with a groove that matches the main shaft J1. When the main shaft J1 has a cylindrical structure, the groove on the upper end face of the limiting component has an arc-shaped structure.

[0032] The mirror body auxiliary support arm 7 has an L-shaped structure, and the mirror body auxiliary support support part 8 has an I-shaped structure. The mirror body auxiliary support support part 8 is fixedly connected to the mirror body auxiliary support arm 7, detachably connected, or integrally formed, so that the whole formed by the mirror body auxiliary support arm 7 and the mirror body auxiliary support support part 8 has an L-shaped structure. The mirror body auxiliary support support part 8 and the support beam J2 have point contact / line contact. A flexible pad is provided at the contact point between the mirror body auxiliary support support part 8 and the support beam J2 to ensure that the mirror body auxiliary support support part 8 and the support beam J2 are completely fitted together, thereby improving the hoisting stability.

[0033] In this embodiment, when hoisting the mirror body, the hoisting rope of the hoisting equipment is connected to the hoisting lug 10 on the upper part of the tooling. The tooling is moved so that its supporting part is located on the lower side of the mirror body, and the main arm 4 is rotated through the swivel joint 3 to put the tooling into place. At this time, the main beam 1 of the tooling is parallel to the main shaft J1, and the main support supporting part 6 of the mirror body is limited to the lower part of the support J3. After the tooling is in place, the swivel joint 3 needs to be locked.

[0034] The lifting fixture is slowly raised upwards. The main support 6 of the mirror body automatically supports the main shaft J1, and the two limiting structures of the main support 6 automatically lock the support J3, restricting the axial sliding of the mirror body. When the mirror body leaves the ground, the secondary support 8 of the mirror body is completely in contact with the support beam J2, restricting the mirror body from flipping in the air.

[0035] Once the telescope body is installed, simply move the fixture downwards; the fixture will automatically detach from the telescope body. Then, move the fixture horizontally to remove it. If horizontal movement is inconvenient, you can also rotate the main arm 4 and then lift the fixture to remove it.

[0036] Example 2:

[0037] Unlike Example 1, as Figure 1-4 As shown in the embodiment of this utility model, the secondary support arm 7 of the heliostat body lifting fixture has an L-shaped structure, and the secondary support support part 8 has a plate-like or ring-like structure. The secondary support arm 7 passes through or is embedded in the secondary support support part 8 and is rotatably connected to it. When the secondary support support part 8 has a plate-like structure, the secondary support arm 7 passes through or is embedded in it; when the secondary support support part 8 has a ring-like structure, the secondary support arm 7 passes through it. By setting the mirror body sub-support 8 as a plate-like structure or a ring-like structure, the mirror body sub-support 8 and the support beam J2 are in surface contact, so as to improve the hoisting stability and distribute the force on the support beam J2, prevent local stress from damaging the support beam J2 and affecting the mirror body accuracy; wherein, the L-shaped mirror body sub-support arm 7 includes a first connecting rod connected to the main arm 4 at one end and a second connecting rod connected to the end of the first connecting rod away from the main arm 4 at the other end. The central axis of the mirror body sub-support arm 7 refers to the central axis of the first connecting rod.

[0038] At this time, the lifting fixture also includes tensioning components 9 symmetrically arranged on both sides of the main boom 4. One end of the tensioning component 9 is connected to the main boom 4 or the main boom support rod provided on the main boom 4, and the other end is connected to the end of the mirror body auxiliary support 8 near the main boom 4. The main boom support rod and the main boom 4 are in an L-shaped structure. The tensioning component 9 can be made of springs, elastic bands, etc. Before lifting the heliostat mirror body, the main support 6 and the auxiliary support 8 of the lifting fixture need to be moved to the bottom of the heliostat mirror body to be lifted. In this way, when the lifting fixture is raised, the main support 6 and the auxiliary support 8 can be used to lift the mirror body. The support part 8 lifts the heliostat body to be lifted. To prevent the secondary support part 8 from interfering with the heliostat body when it moves under the heliostat body, the tensioning part 9 connects the inner side of the secondary support part 8 to the main arm 4 or the main arm support rod. When the lifting fixture is not in contact with the heliostat body, the secondary support part 8 can remain horizontal under the tensioning part 9, thus preventing interference between the secondary support part 8 and the heliostat body during the process of moving under the heliostat body. At the same time, the tensioning part 9 can also prevent the secondary support part 8 from rotating arbitrarily when it is not supported.

[0039] In this embodiment, when hoisting the mirror body, the hoisting rope of the hoisting equipment is connected to the hoisting lug 10 on the upper part of the tooling. The tooling is moved so that its supporting part is located on the lower side of the mirror body, and the main arm 4 is rotated through the swivel joint 3 to put the tooling into place. At this time, the main beam 1 of the tooling is parallel to the main shaft J1, and the main support supporting part 6 of the mirror body is limited to the lower part of the support J3. After the tooling is in place, the swivel joint 3 needs to be locked.

[0040] The lifting fixture is slowly raised, and the main support 6 of the mirror body automatically supports the main shaft J1. The two limiting structures of the main support 6 also automatically engage the support J3, restricting the sliding of the mirror body along the axial direction of the main shaft J1. Simultaneously, due to the pressure of the mirror body on the secondary support 8, the secondary support 8 rotates around its axis. When the mirror body leaves the ground, the secondary support 8 is perfectly aligned with the support beam J2, preventing the mirror body from flipping in the air.

[0041] Once the telescope body is installed, simply move the fixture downwards; the fixture will automatically detach from the telescope body. Then, move the fixture horizontally to remove it. If horizontal movement is inconvenient, you can also rotate the main arm 4 and then lift the fixture to remove it.

[0042] Example 3:

[0043] Based on Example 1 or Example 2, such as Figure 1 and Figure 3As shown, the heliostat lifting fixture provided in this embodiment of the present invention also includes a telescopic arm 2 that can extend and retract along the main beam 1. One end of the telescopic arm 2 is connected to the main beam 1, and the other end is connected to the main arm 4 through a swivel joint 3. Preferably, the telescopic arm 2 has an L-shaped structure. By setting the telescopic arm 2 that can extend and retract along the main beam, the fixture can be used in a variety of situations and can also adapt to more types of heliostats, thereby improving the versatility of the fixture.

[0044] In this embodiment, when hoisting the mirror body, the hoisting rope of the hoisting equipment is connected to the lifting lug 10 on the upper part of the tooling, and the tooling is moved so that its supporting part is located under the mirror body. When it is inconvenient to move the tooling due to the position of the mirror body, the position of the telescopic arm 2 can be adjusted and / or the main arm 4 can be rotated through the swivel joint 3 to position the tooling. At this time, the main beam 1 of the tooling is parallel to the main shaft J1, and the main support support part 6 of the mirror body is limited to below the support J3. After the tooling is in place, the telescopic arm 2 and the swivel joint 3 need to be locked.

[0045] The lifting fixture is slowly raised upwards. The main support 6 of the mirror body automatically supports the main shaft J1, and the two limiting structures of the main support 6 automatically engage the support J3, restricting the sliding of the mirror body along the axial direction of the main shaft J1. When the mirror body leaves the ground, the secondary support 8 of the mirror body is completely in contact with the support beam J2, restricting the mirror body from flipping in the air.

[0046] Once the scope body is installed, simply move the fixture downwards; the fixture will automatically detach from the scope body. Then, move the fixture horizontally to remove it. If horizontal movement is inconvenient, you can rotate the main arm 4 and / or move the telescopic arm 2 outwards, then lift the fixture to remove it.

[0047] The specific embodiments of this utility model have been described above. It should be understood that this utility model is not limited to the specific embodiments described above, and those skilled in the art can make various changes or modifications within the scope of the claims, which do not affect the substantive content of this utility model.
