Description

Technical Field

[0001] The present invention relates to the field of cableway support lifting, and in particular to a device and method for lifting and installing an inverted support of a passenger cableway. Background Art

[0002] The function of the cableway support is to support the cableway carrying rope and provide supporting force for it so that the cableway carrying rope can drive the gondola to move. The main components of the cableway support are steel columns, ladders arranged on the outside of the steel columns, lifting beams and cross beams arranged horizontally on the outside of the steel columns, guardrails installed on the cross beams, and support and pressure rope pulley groups for supporting the movement of the cableway carrying rope are installed on both sides of the cross beams. The existing cableway supports are mainly divided into conventional supports and inverted supports. The conventional supports mainly install the steel columns on the ground and support the remaining equipment through the steel columns, while the inverted supports mainly install the steel columns on the inner walls of caves and mountains and hang the remaining equipment upside down through the steel columns. Therefore, when installing the inverted supports, manual labor is required to install the steel columns on the inner wall through separate lifting equipment, and then lift the remaining equipment through a variety of different types of lifting equipment and install them on the side of the steel columns.

[0003] Since there is not enough platform for construction workers to move and operate, manual operation is more troublesome when installing parts and there is a risk of falling. In addition, since inverted brackets are usually installed in places that are not suitable for installing conventional brackets, that is, the ground and construction space cannot accommodate too much lifting equipment, the efficiency of bracket installation is further reduced.

[0004] With the advancement of science and technology, technicians in related fields have also optimized the process of installing the inverted bracket. In order to make a more accurate comparison, for example, the Chinese patent publication number CN201882873U discloses a mast seat for installing an overhead passenger ropeway tower.

[0005] The mast fixing seat is mainly composed of a horizontal panel, front and rear lower vertical plates and a lower cross plate, and the curvature of the concave arc surface at the right end of the horizontal panel corresponds to the curvature of the outer wall of the tower cylinder. A pin sleeve is welded on the outer wall of the tower cylinder, and the right end of the horizontal panel is pressed against the outer wall of the tower cylinder. Positioning pins are correspondingly inserted into the long waist-shaped pin holes on the horizontal panel and the pin sleeves, and the base is installed on the tower cylinder. A mast fixing seat is installed on the base, and the mast fixing seat is mainly welded by a rectangular panel, front and rear upper vertical plates, a rib plate and a screw. The mast is hinged to the mast fixing seat, and the lower section of the tower cylinder is used as a temporary support to install the mast, to hoist the upper section of the tower cylinder, and hoist them in sections in sequence until they are assembled into an integral tower.

[0006] However, when the above-mentioned prior art is used to lift and install the cableway support, the following problems still exist: 1. Although the above-mentioned prior art can fix the entire installation device on the ground by plugging the mast into the fixed base and then lifting the bracket, the overall stability of the mast cannot be guaranteed. When lifting some brackets with larger volume and weight, the entire bracket is lifted except for the top, but there is no support and limit assembly on the side to limit it. When there is wind, the bracket may be affected by the wind and shake, making it impossible to ensure the installation accuracy and safety.

[0007] 2. The above-mentioned existing device does not have a platform for construction workers to install and stand. That is, when the bracket is suspended in the air, the construction workers still need to use the existing lifting device to lift it to the air corresponding to the horizontal height of the bracket to install and fix it. The overall structure of the above-mentioned existing technology is relatively simple. When dealing with the installation of some brackets with more complex structures, the bracket needs to be lifted back and forth multiple times to install the bracket, which is not only inefficient, but also further increases the risk of safety accidents for construction workers.

[0008] Therefore, based on the above-stated viewpoint, there is still room for optimization in the installation method of the cableway support in the prior art. Summary of the Invention

Then, workers can install the ropeway bracket on the present invention. After installation, the present invention is used to lift the ropeway bracket, and then the ropeway bracket is fixed at the fixed point.

[0040] Embodiment 1: Refer to Figure 1 It should be noted that there may be an error in the tag "[[ID=3!]]" in the original text. It is recommended to check and correct it to ensure the accuracy of the translation.As shown, it includes a base plate 1, a trapezoidal block 10, a C-shaped frame 11, a C-shaped extension frame 12, a rectangular groove 13, an installation unit 2 and a lifting unit 3. The base plate 1 is provided with a trapezoidal block 10, and the trapezoidal block 10 is provided with a C-shaped frame 11. The trapezoidal block 10 is used to support the C-shaped frame 11 and increase the distance between the C-shaped frame 11 and the base plate 1; a number of C-shaped extension frames 12 are installed on the C-shaped frame 11, and rectangular grooves 13 are provided on three surfaces of the C-shaped frame 11 and the C-shaped extension frame 12. The C-shaped frame 11 can support the C-shaped extension frame 12, and the rectangular grooves 13 are used to reduce the weight of the C-shaped frame 11 and the C-shaped extension frame 12.

[0041] An installation unit 2 for limiting and supporting the steel column is commonly provided between the U-shaped frame 11 and the U-shaped expansion frame 12, and a lifting unit 3 for driving the U-shaped expansion frame 12 to rise is also provided on one side of the U-shaped frame 11 and the U-shaped expansion frame 12. Before construction, the U-shaped expansion frame 12 is first lifted onto the U-shaped frame 11 by the lifting unit 3, and then the steel pipe is placed on the installation unit 2 through the opening on one side of the U-shaped frame 11 and the U-shaped expansion frame 12, and the steel pipe is limited by the installation unit 2, and then the steel pipe is lifted.

[0042] Continue to refer to Figure 1 、 Figure 2 and Figure 3 As shown, an installation unit 2 for limiting the support of the steel column is commonly provided between the C-shaped frame 11 and the C-shaped extension frame 12; specifically, the installation unit 2 includes a rectangular plate 20, a circular through groove 21, a sliding plate 22, an arc-shaped plate 23, an arc groove 24, a driving ring 25, a driving shaft 26, a driving block 27 and a driving cylinder 28. The rectangular plate 20 is slidingly arranged on the inner wall of the C-shaped frame 11, and the side surface of the rectangular plate 20 corresponds to the inner wall of the C-shaped extension frame 12, that is, when the rectangular plate 20 is driven by external force, it can move up and down along the inner wall of the C-shaped frame 11 and the C-shaped extension frame 12; a circular through groove 21 is provided on the rectangular plate 20, and the steel pipe enters the circular through groove 21 on the rectangular plate 20 through an opening on one side of the C-shaped frame 11, and its bottom will contact the trapezoidal block 10.

[0043] Sliding grooves are symmetrically provided on the inner wall of the circular through groove 21, and a sliding plate 22 is slidingly provided in the sliding groove. An arc-shaped contact plate 23 is provided on the side of the sliding plate 22 close to the axis of the circular through groove 21, that is, the two sliding plates 22 can move toward or away from the axis of the circular through groove 21 in the corresponding sliding groove. The sliding plate 22 drives the corresponding arc-shaped contact plate 23 to move during the movement, and the arc-shaped contact plate 23 contacts the outer side of the steel pipe to clamp and limit the steel pipe.

[0044] An arc groove 24 corresponding to the axis of the circular through groove 21 is opened in the middle of the symmetrically distributed sliding plate 22, and a driving ring 25 is commonly threaded in the arc groove 24 on the two sliding plates 22. A driving shaft 26 is rotatably provided on one side of the driving ring 25, and a driving block 27 is rotatably sleeved on the outer side of the driving shaft 26. A driving cylinder 28 connected to the cylinder shaft and the driving block 27 is rotatably provided on the rectangular plate 20 through the cylinder seat. The driving cylinder 28 can drive the driving ring 25 to rotate along the axis of the circular through groove 21 through the driving block 27 and the driving shaft 26, and when the driving ring 25 rotates, it can drive the two sliding plates 22 to move in relative directions in the sliding groove by threaded cooperation.

[0045] Reference Figure 4 and Figure 5 As shown, a lifting unit 3 is further provided on one side of the C-shaped frame 11 and the C-shaped extension frame 12 for driving the C-shaped extension frame 12 to rise; specifically, the lifting unit 3 includes a through groove 30, a driving screw 31, a driving plate 32, a sliding groove 33, a sliding plate 34, a semicircular plate 35, a strip groove 36, a driving rack 37, a rotating shaft 38, a transmission gear 39 and a circular plate 310. The through groove 30 is provided on one side of the C-shaped frame 11 and the C-shaped extension frame 12, and the through groove 30 is connected to the corresponding rectangular groove 13. A driving screw 31 located in the through groove 30 is rotatably installed on the trapezoidal block 10, and a driving plate 32 threadedly connected to the driving screw 31 is provided on one side of the rectangular plate 20. A reciprocating threaded groove is provided on the driving screw 31, that is, when the driving screw 31 is driven to rotate by an external force, the rectangular plate 20 can be driven to move up and down through the driving plate 32.

[0046] Sliding grooves 33 are provided on the inner walls on both sides of the through groove 30 on the U-shaped extension frame 12, and a sliding plate 34 is slidingly arranged in the sliding groove 33. A semicircular plate 35 is provided on the side of the sliding plate 34 close to the driving screw 31, and the corresponding two semicircular plates 35 cooperate with each other and are threadedly connected to the driving screw 31. When driven by external force, the sliding plate 34 can drive the semicircular plates 35 to move in relative directions. When the two corresponding semicircular plates 35 are in contact with the driving screw 31, the driving screw 31 rotates and the U-shaped extension frame 12 can be driven to move in the up and down directions through the semicircular plates 35, the sliding plates 34 and the sliding grooves 33.

[0047] A strip groove 36 is provided on the sliding plate 34, and a driving rack 37 is provided on the inner wall of one side of the strip groove 36. A rotating shaft 38 is rotatably provided on the inner wall of the rectangular groove 13 on one side of the U-shaped extension frame 12, and is connected to the strip groove 36. One end of the rotating shaft 38 is provided with a transmission gear 39 located in the strip groove 36 and meshing with the driving rack 37. A circular plate 310 is also provided on the other side of the rotating shaft 38, which is located outside the strip groove 36. A hexagonal groove is provided on the circular plate 310. The device is driven by an external When inserted into the hexagonal slot 1, the circular plate 310 can drive the rotating shaft 38 to rotate, and the rotating shaft 38 can drive the transmission gear 39 to rotate. When the transmission gear 39 rotates, it can drive the sliding plate 34 to move in the sliding slot 33 by driving the rack 37. A damping device is also provided between the rotating shaft 38 and the U-shaped extension frame 12 to limit the rotating shaft 38. When the rotating shaft 38 is not driven by external force, the rotating shaft 38 is prevented from rotating, thereby indirectly limiting the semicircular plate 35.

[0048] The "external driving device" proposed in the above implementation process is a prior art, and its purpose is to indirectly drive the rotating shaft 38 to rotate through the hexagonal groove.

[0049] Similarly, the “damping device” mentioned above is a prior art, and its purpose is to provide a limit for the rotating shaft 38 , so it will not be described in detail in this implementation process.

[0050] In practical applications, first, the U-shaped expansion frame 12 is moved to correspond to the driving screw rod 31 through the trapezoidal block 10. Then, the side of the U-shaped expansion frame 12 with the through groove 30 is made to correspond to the side of the U-shaped frame 11 with the through groove 30. That is, at this time, the U-shaped expansion frame 12 and the U-shaped frame 11 are placed in opposite directions. Since the outer wall of one side of the through groove 30 of the U-shaped frame 11 is smaller than that of the U-shaped expansion frame 12, the two semi-circular plates 35 can be moved to correspond to the driving screw rod 31. Then, through the hexagonal groove 1, the two semi-circular plates 35 are indirectly driven to be in close contact with the driving screw rod 31 and are threadedly connected. After that, the driving screw rod 31 rotates. Since one side of the U-shaped expansion frame 12 contacts the U-shaped frame 11, the driving screw rod 31 can indirectly drive the U-shaped expansion frame 12 to rise through the semi-circular plates 35. When the U-shaped expansion frame 12 moves to a certain height, at this time, the next U-shaped expansion frame 12 is moved to be threadedly connected to the driving screw rod 31. The U-shaped expansion frames 12 contact each other and limit each other's movement, and move synchronously. When all the U-shaped expansion frames 12 move to a fixed height, at this time, an external force is used to drive them together to make the U-shaped expansion frames 12 flip along the axis of the driving screw rod 31, so that the U-shaped expansion frames 12 flip to correspond to the U-shaped frame 11. And when swinging, the driving screw rod 31 will also rotate synchronously with the U-shaped expansion frame 12. After the installation of the U-shaped expansion frame 12 is completed, at this time, through the hexagonal groove 1, the semi-circular plates 35 are indirectly driven to no longer be threadedly connected to the driving screw rod 31. Then, the rectangular plate 20 together with the driving plate 32 is placed on the driving screw rod 31, and the driving screw rod 31 is used to drive the rectangular plate 20 to move to the trapezoidal block 10.

[0051] Refer to Figure 6 As shown, that is, a side lifting unit 4 for lifting the bracket is also provided on one side of the U-shaped frame 11 and the U-shaped expansion frame 12. Specifically, the side lifting unit 4 includes a lifting groove 40, a lifting screw rod 41, a C-shaped plate 42, C-shaped side plates 43, a support column 44, and a triangular inclined plate 45. The two lifting grooves 40 are symmetrically opened on one side of the U-shaped frame 11 and the U-shaped expansion frame 12. A lifting screw rod 41 is rotatably provided on the inner bottom wall of the lifting groove 40, and the upper end of the lifting screw rod 41 is inserted and installed with several lifting screw rods 41 until the inner top wall of the lifting groove 40 through pin shafts. A C-shaped plate 42 threadedly connected to it is jointly provided between the two lifting screw rods 41. That is, after the installation of the U-shaped expansion frame 12 is completed, at this time, several lifting screw rods 41 are installed together. Then, one side of the lifting screw rod 41 is threadedly inserted into one side of the C-shaped plate 42. Subsequently, the assembled lifting screw rods 41 are rotatably installed in the lifting groove 40. And when the lifting screw rod 41 is driven by an external force to rotate, it can drive the C-shaped plate 42 to move in the up and down direction under the limitation of the lifting groove 40. And a reciprocating thread groove is opened on the outer side of the lifting screw rod 41. Therefore, the lifting screw rod 41 can drive the C-shaped plate 42 to move reciprocally.

[0052] On both sides of the U-shaped plate 42, there are also U-shaped side plates 43, which can move synchronously with the U-shaped plate 42; circular grooves are provided on the inner walls of both sides of the U-shaped side plates 43, and support columns 44 for supporting the bracket are threadedly inserted into the corresponding circular grooves. Hexagonal grooves II are also provided on the support columns 44. The external driving device can drive the support columns 44 to move back and forth in the circular grooves through the hexagonal grooves II. By changing the distance between the support columns 44, the bracket components, such as the support and pressing cable wheel groups on both sides of the steel column, can be supported. The distance between both sides of the support columns 44 can avoid and clamp the support and pressing cable wheel groups. The components and the steel column are indirectly driven by the rectangular plate 20 and the U-shaped side plates 43 to the installation height. First, the steel column is placed at the target point, such as the inner wall of the cave, and then the components on both sides are installed outside the steel column.

[0053] It should be noted that the "components" are the general term for other parts of the cableway bracket except the steel column.

[0054] On the side of the U-shaped plate 42 away from the U-shaped frame 11, there is a triangular inclined plate 45 corresponding to the bottom plate 1. When the U-shaped plate 42 is at the bottom of the lifting groove 40, the triangular inclined plate 45 corresponds to the bottom plate 1 and is used to compensate for the distance between the U-shaped plate 42 and the bottom plate 1. The steel column and the components can move along the triangular inclined plate 45 to the rectangular plate 20 and the U-shaped plate 42.

[0055] Continue to refer to Figure 6 As shown, that is, a protection component 5 for protecting construction workers is provided on the rectangular plate 20 and the U-shaped plate 42; specifically, the protection component 5 includes guardrails 50. A plurality of guardrails 50 are provided at the upper ends of the rectangular plate 20 and the U-shaped side plates 43. The guardrails 50 are used to block and protect construction workers. During the construction process, construction workers can stand on the rectangular plate 20 and the U-shaped side plates 43 and move synchronously to assist in installing the steel column and the components.

[0056] Embodiment 2: Refer to Figure 7 [[ID=1,6]]and Figure 8 As shown, on the basis of Embodiment 1, a limiting component 6 for limiting the U-shaped extension frame 12 is also provided on the U-shaped frame 11 and the U-shaped extension frame 12; specifically, the limiting component 6 includes clamping grooves 60, push spring columns 61 and sliding wheels 62. A plurality of clamping grooves 60 are opened at the upper ends of the U-shaped frame 11 and the U-shaped extension frame 12. Four clamping grooves 60 are symmetrically arranged at the lower ends of the U-shaped frame 11 and the U-shaped extension frame 12. Four push spring columns 61 located in the corresponding clamping grooves 60 are provided at the lower end of the U-shaped extension frame 12.

[0057] A sliding wheel

[0058] During the actual installation process, when moving the U-shaped extension frame 12, the U-shaped extension frame 12 can be moved on the ground by the sliding wheel 62. When several U-shaped extension frames 12 contact and correspond to each other, the corresponding push spring column 61 will push the sliding wheel 62 to move into the corresponding clamping groove 60 at the lower end, and clamp and limit each other. When the construction is completed, an external force is applied to the U-shaped extension frame 12, so that the U-shaped extension frame 12 swings along the axis of the driving screw rod 31. During the swinging process, the sliding wheel 62 under the C-shaped extension frame 12 on the C-shaped frame 11 will disengage from the corresponding clamping groove 60. At this time, the telescopic end of the push spring column 61 will be extended and retracted, so that the C-shaped extension frame 12 is no longer restricted by the clamping groove 60 on the C-shaped frame 11. Then, the threaded connection between the semicircular plate 35 and the driving screw 31 is indirectly released through the hexagonal groove. At this time, the C-shaped extension frame 12 will slide onto the ladder frame, and then several C-shaped extension frames 12 can be gradually separated.

[0059] Example 3: Reference Figure 9 and Figure 10 As shown, on the basis of embodiment one and embodiment two, a rectangular cavity is provided in the trapezoidal block 10, and one end of the driving screw 31 and the lifting screw 41 located at the bottom end rotates through the corresponding outer wall of the trapezoidal block 10 and the outer wall of the lifting groove 40 and is located in the rectangular cavity, and in order to drive the driving screw 31 and the lifting screw 41 to rotate, a driving unit 7 is provided in the rectangular cavity; specifically, the driving unit 7 includes a ratchet part 70, an outer gear ring 71, a driving motor 72 and a driving gear 73, the ratchet part 70 is sleeved on the driving screw 31 and the lifting screw 41 on one side and is located on one end of the rectangular cavity, and the ratchet part 70 includes a ratchet sleeved on the outside of the driving screw 31 and the lifting screw 41, a ring is rotatably sleeved on the outside of the ratchet, a ratchet shaft is provided on the inner wall of the ring, a plurality of ratchets distributed around its axis are provided on the outside of the ratchet, a pawl is rotatably sleeved on the outside of the ratchet shaft that engages with the corresponding ratchet teeth, and the extension directions of the ratchets on the two ratchet parts 70 are opposite.

[0060] That is, when the ring is driven by external force, it can drive the ratchet to rotate through the ratchet shaft, pawl and ratchet groove, so that the ratchet can drive the corresponding driving screw 31 or lifting screw 41 to rotate. Because the ratchet grooves on the two ratchets extend in opposite directions, when the two rings rotate in the same direction, only one ring can indirectly drive the corresponding ratchet to rotate.

[0061] The outer side of the ratchet piece 70 on the driving screw 31 is provided with an outer gear ring 71, that is, the outer gear ring 71 is sleeved on the outer side of the ring, and a driving motor 72 is provided on the inner wall of the rectangular cavity through the motor seat. The outer side of the motor shaft of the driving motor 72 is sleeved with a driving gear 73 that meshes with the outer gear ring 71, and the two outer gear rings 71 are connected by a belt transmission, and the two lifting screws 41 are also connected by a belt transmission. The driving motor 72 can drive the driving gear 73 to rotate, and the driving gear 73 can drive the ring corresponding to the driving screw 31 to rotate. When the ring rotates, it can drive the other ring to rotate synchronously. In actual use, the driving motor 72 indirectly drives the ring to rotate counterclockwise. At this time, the rotation direction of the ring corresponds to the ratchet groove corresponding to the lifting screw 41. Therefore, the lifting screw 41 on one side can rotate, and the two lifting screws 41 achieve synchronous rotation through belt transmission. Conversely, when the driving motor 72 indirectly drives the ring to rotate clockwise, it can drive the driving screw 31 to rotate alone.

[0062] It should be noted that, when the U-shaped extension bracket 12 drives the driving screw 31 to rotate, the rotation direction of the driving screw 31 is opposite to the rotation direction of the corresponding ratchet member 70, so that the motor shaft of the driving motor 72 is not driven to rotate.

[0063] In addition, the present invention also provides a method for lifting and installing an inverted support for a passenger ropeway, comprising the following steps: S1, installation preparation: Place the trapezoidal block 10 and the C-shaped frame 11 on the construction site floor 1, and then lift several C-shaped extension frames 12 through the lifting unit 3 according to the construction height, and gradually install the C-shaped extension frames 12 in parallel and vertically on the C-shaped frame 11 to increase the lifting height of the steel column by the installation unit 2.

[0064] S2, lifting the steel column: place the steel column on the rectangular plate 20, and use the installation unit 2 to limit the bottom of the steel column. According to the actual installation situation, after the steel column is located in the circular through groove 21, first adjust the height of the rectangular plate 20, and then use the installation unit 2 to clamp the outer side of the steel column to achieve the clamping effect of the sides of the steel column at different heights to cope with different installation methods.

[0065] S3, bracket lifting: After the remaining bracket parts on the outside of the steel column are installed, the rectangular plate 20 is driven by external force to drive the steel column to rise to a predetermined height through the installation unit 2, so that the top of the steel column is in close contact with the installation position. At the same time, the remaining parts of the bracket can be supported by the side lifting unit 4, and then the parts are installed on the steel column, and then the steel column is installed at the installation point to complete the installation work.

[0066] S4, disassembly completed: After the installation is completed, the U-shaped extension frame 12 is removed from the U-shaped frame 11, and then the U-shaped extension frames 12 are separated from each other, disassembled and dispersed for subsequent transportation.

Therefore, the embodiments should be considered in all respects as exemplary and non-restrictive.
