Description

Technical Field

[0001] This application relates to the technical field of wall-mounted devices, and in particular to a tower crane wall-mounted structure and its construction method. Background Technology

[0002] Tower cranes, also known as tower hoists, are mainly used for the vertical and horizontal transport of materials and the installation of building components during construction. When the height of a tower crane exceeds a certain limit, a wall-mounted structure is required to improve its stability and safety.

[0003] Currently, Chinese utility model patent CN205275069U discloses a tower crane wall-mounted connection structure, including wall-mounted members. One end of the wall-mounted member is fixedly connected to a connector, which is a frame enclosing a concrete column. The other end of the wall-mounted member is fixedly connected to the tower body of the tower crane. An adjusting plate is provided on the frame, and the adjusting plate is fixedly connected to the frame. Several adjusting rods that are threaded into the adjusting plate are provided on the adjusting plate, and each adjusting rod passes through the adjusting plate and abuts against the concrete column.

[0004] However, when the thickness of the concrete column connected to the connector is small, the support provided by the wall-mounted structure to the tower crane is poor, which has a certain impact on the stability of the tower crane. Summary of the Invention

[0005] To improve the stability of tower cranes, this application provides a tower crane wall-mounted structure and its construction method.

[0006] Firstly, this application provides a tower crane wall-mounted structure, which adopts the following technical solution: A tower crane wall-mounted structure, including A ring-shaped frame is installed on the outer periphery of the tower crane; A wall-mounting assembly, installed on a building, includes a first wall-mounting plate, a second wall-mounting plate, a fixing component, and a connecting rod; The first wall panel is symmetrically arranged and cooperates to clamp the concrete column, the second wall panel is symmetrically arranged and cooperates to clamp the next adjacent concrete column, and the first wall panel and the second wall panel are arranged parallel to each other along the same straight line. The first wall panels are fixed to the concrete column by the fixing components, and the second wall panels are fixed to the concrete column by the fixing components. The connecting rod is disposed between adjacent first and second wall panels and is fixedly connected; A strut connects the annular frame to the first wall panel located away from the second wall panel; A set of fixing plates is provided on the annular frame and on the first wall panel away from the second wall panel, and two fixing plates are symmetrically arranged in each set of fixing plates. The fixing plates in the same group have mutually aligned fixing holes, and the support rods have connecting holes on both sides, with the fixing holes and connecting holes being adapted to each other; A pin connects the fixing plate and the support rod, and the pin passes through the mutually aligned fixing hole and the connecting hole; The pin has symmetrical mounting grooves formed on its outer periphery, located between the support rod and the upper and lower fixing plates, respectively. The fixing blocks are in multiple sets, each set being disposed in one of the mounting slots. Each set of the fixing blocks consists of two blocks that slide vertically within the mounting slot. The side wall of the fixing block is provided with a guide block that slides up and down on the pin, and the opposite sides of the fixing blocks in the same group are respectively slidably connected with abutment plates that can protrude out of the mounting groove. A drive shaft is rotatably connected to a pin. The drive shaft and the pin are slidably connected vertically and coaxially arranged. The pin protrudes out of the pin. A drive assembly is provided on the pin. When the drive shaft rotates forward, the drive assembly drives the fixed blocks in the same group to move away from each other. At this time, the abutment plate slides out of the mounting groove until it abuts the fixed plate and the support rod. When the drive shaft reverses, the drive assembly drives the fixed blocks in the same group to move closer to each other, at which time the abutment plate slides into the mounting groove.

[0007] By adopting the above technical solution, during operation, the force on the tower crane is transmitted to the first wall-mounted plate through the struts, and then the first wall-mounted plate transmits the force to the building, providing support for the tower crane. Simultaneously, the force is transmitted to the second wall-mounted plate through the connecting rods, further enhancing the building's support capacity for the tower crane and increasing its stability. Furthermore, when the drive shaft rotates, the drive assembly causes the abutment plate to abut against the struts and the fixing plate, which helps reduce the difficulty of installing the struts and facilitates the alignment of the fixing holes and connecting holes.

[0008] Optionally, the drive assembly includes a drive sleeve, a power sleeve, a power block, a push block, a drive block, a drive rope, and a tension spring; The drive ropes are slidably threaded through the fixed blocks in the same group, and the two ends of the drive ropes are respectively connected to the opposite abutment plates. When the fixed blocks in the same group move away from each other, the drive ropes pull the opposite abutment plates to slide out of the mounting groove. The pushing block corresponds to the mounting slot one by one, the pushing block slides in the pin, and the upper and lower pushing blocks are respectively located between the fixed blocks in the same group; The fixed blocks in the same group are each inclined to form a pushing surface for the pushing block to slide on. When the pushing block slides on the pushing surface, the pushing blocks in the same group move away from each other. The drive sleeve slides up and down inside the pin, and the drive block and the push block correspond one-to-one and are disposed on the outer wall of the drive sleeve; The push block is inclined to form a transmission surface for the drive block to slide on. When the drive block slides on the transmission surface, the push block slides away from the drive sleeve. The power sleeve is slidably sleeved on the outer periphery of the drive shaft and coaxially arranged. The power sleeve is threadedly connected to the pin. A power block is provided on the outer periphery of the power sleeve. When the power sleeve moves downward, the power block pushes the drive sleeve to move downward. The tension spring corresponds to the abutment plate and is disposed on the fixed block. When the driving block moves away from the pushing block, the tension spring pulls the abutment plate to slide into the mounting groove. At this time, the driving rope drives the fixed blocks in the same group to move closer to each other.

[0009] By adopting the above technical solution, when the two fixed blocks in the same group are far apart, the drive rope pulls the abutment block to slide out of the mounting groove, so that the fixed plate and the support rod can abut against the abutment plate; and when the tension spring pulls the abutment plate to slide, the drive rope can pull the two fixed blocks in the same group closer to each other.

[0010] Optionally, the drive shaft has an actuation groove located outside the pin.

[0011] By adopting the above technical solution, it is convenient to rotate the drive shaft by inserting the rod or columnar tool into the actuation slot, thus reducing the difficulty of rotating the drive shaft.

[0012] Optionally, the diameter of the pin is smaller than the diameter of the fixing hole and the connecting hole.

[0013] By adopting the above technical solution, it is convenient to insert the pin into the connecting hole and the fixing hole.

[0014] Optionally, the outer periphery of the pin is provided with circumferentially spaced receiving grooves, and the pin is provided with a support plate that slides in the receiving grooves; Multiple support columns are arranged circumferentially on the outer periphery of the pin. The support columns slide on the pin and are perpendicular to each other. The ends of the support columns are fixed to the middle of the support plate. The drive sleeve includes an upper sleeve and a lower sleeve, and a fixing post connects the upper sleeve and the lower sleeve; The pin is provided with a mounting ring that slides up and down on the fixed post, and a transmission sleeve is rotatably connected to the outer circumference of the drive shaft. The transmission sleeve is threadedly connected to the mounting ring. A transmission block is provided on the outer periphery of the mounting ring. The transmission block is inclined to form a sliding surface for the support column to slide. When the support column slides on the sliding surface, the transmission block pushes the support column to slide outward toward the pin until the support plate abuts against the connecting hole and the wall of the fixing hole. The pin is provided with an elastic reset member. When the transmission block moves away from the support column, the elastic reset member drives the support column to slide into the pin. The power sleeve is rotatably connected to the drive shaft; The pin is equipped with a control component, which controls the transmission sleeve and the drive shaft to enter a linkage state, at which time the power sleeve and the drive shaft rotate relative to each other; or the control component controls the power sleeve and the drive shaft to enter a linkage state, at which time the transmission sleeve and the drive shaft rotate relative to each other.

[0015] By adopting the above technical solution, the support plate abuts against the walls of the connecting hole and the fixing hole, reducing the possibility of the pin moving in the horizontal direction.

[0016] Optionally, the control component includes a control column, an upper push block, a lower push block, an upper linkage block, a lower linkage block, an upper spring, and a lower spring; The control column slides up and down on the drive shaft and is coaxially arranged, with the control column protruding outside the drive shaft; The upper linkage block slides on the drive shaft, and the inner peripheral sidewall of the power sleeve forms a first slot for the upper linkage block to be inserted. The push block is disposed on the outer periphery of the control column. The push block is inclined to form an upward push surface. When the upper linkage block slides on the upward push surface, the push block pushes the upper linkage block to insert into the first slot. The upper spring is disposed on the drive shaft. When the upper push block is away from the upper linkage block and the upper linkage block is aligned with the first slot, the upper spring pushes the upper linkage block to slide out of the first slot. The lower linkage block slides on the transmission sleeve, and a second slot is formed on the outer periphery of the drive shaft for the lower linkage block to be inserted and slide up and down. The push block is disposed on the outer periphery of the control column. The push block is inclined to form a push surface. When the lower linkage block slides on the push surface, the push block pushes the lower linkage block to slide out of the second slot. The lower spring is disposed on the transmission sleeve. When the lower push block is away from the lower linkage block and the lower linkage block is aligned with the second slot, the lower spring pushes the lower linkage block to insert into the second slot. When the upper linkage block is inserted into the first slot, the lower linkage block disengages from the second slot; When the lower linkage block is inserted into the second slot, the upper linkage block disengages from the first slot.

[0017] By adopting the above technical solution, the abutment plate and the support plate are driven separately, reducing the possibility that the support plate will not abut against the wall of the connecting hole or the fixing hole when the abutment plate stops moving.

[0018] Optionally, a limiting block is provided on the outer periphery of the support column, and the pin is formed with a limiting groove for the limiting block to slide. The elastic reset component is a reset spring, which is installed in the limiting groove. One end of the reset spring abuts against the side of the limiting block near the support plate, and the other end abuts against the wall of the limiting groove.

[0019] By adopting the above technical solution, the reset spring pushes the limiting block, causing the support column to slide into the pin column, so that the support plate can move back into the receiving groove.

[0020] Secondly, this application provides a construction method for a tower crane wall-mounted structure, employing the following technical solution: A construction method for a tower crane wall-mounted structure includes the following steps: S1: Pre-embedded construction of wall-mounted components; S2: The ring frame is installed; S3: The support rod is positioned such that the fixing hole is aligned with the connecting hole; S4: Pass the pin through the fixing hole and the connecting hole, and rotate the drive shaft clockwise, so that the drive assembly drives the fixing blocks in the same group to move away from each other until the abutting plate abuts the support rod and the fixing plate respectively.

[0021] By adopting the above technical solution, during installation, rotating the drive shaft causes the drive assembly to drive the fixed blocks in the same group to move away from each other, so that the abutment plate abuts against the support rod and the fixed plate, which helps to reduce the difficulty of installing the pin.

[0022] In summary, this application includes at least one of the following beneficial effects: 1. The first wall panel transmits the force to the second wall panel through the connecting rod, which improves the building's support capacity for the tower crane and helps to enhance the stability of the tower crane; 2. The pin is fixed by the support plate abutting against the wall of the fixing hole and the connecting hole, which helps to reduce the difficulty of installing the pin. Attached Figure Description

[0025] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0026] This application discloses a tower crane wall-mounted structure. See also... Figure 1 and Figure 2 The tower crane wall-mounted structure includes a ring frame 1, a wall-mounted component, a fixing component, a strut 3, and a pin 5. The ring frame 1 is fixed to the outer periphery of the tower crane. The wall-mounting assembly includes a first wall-mounting plate 2, a second wall-mounting plate 21, a fixing component, and a connecting rod 22. There are multiple sets of first wall-mounting plates 2, which are evenly spaced horizontally along the extension direction of the concrete column. Each set contains two first wall-mounting plates 2 arranged symmetrically, and the two first wall-mounting plates 2 in the same set cooperate to clamp the concrete column. The fixing component includes bolts 23 and nuts 24, and the two first wall-mounting plates 2 in the same set are clamped to the concrete column using bolts 23 and nuts 24.

[0027] There are multiple sets of second wall-mounted panels 21, with two panels in each set, symmetrically arranged on both sides of the next adjacent concrete column. Each set of second wall-mounted panels 21 corresponds to a set of first wall-mounted panels 2, and the corresponding first wall-mounted panels 2 and second wall-mounted panels 21 are arranged in the same straight line direction. The two second wall-mounted panels 21 in the same set are clamped to the concrete column by bolts 23 and nuts 24.

[0028] The first wall panel 2 and the second wall panel 21 can be installed in advance during the building pouring process, and then reserved in the concrete column during concrete pouring.

[0029] There are multiple connecting rods 22, each of which is respectively set between two sets of corresponding first wall-mounted plates 2 and second wall-mounted plates 21. The two ends of the connecting rod 22 are respectively fixedly connected to the corresponding first wall-mounted plate 2 and second wall-mounted plate 21.

[0030] There are multiple support rods 3, each corresponding to a set of first wall-mounted panels 2. On the side of the first wall-mounted panel 2 away from the second wall-mounted panel 21, and on the side wall of the annular frame 1, fixing plates 4 are symmetrically fixed, one above the other. The fixing plates 4 on the annular frame 1 correspond to the fixing plates 4 on the first wall-mounted panel 2. One end of the support rod 3 extends between the two fixing plates 4 of the first wall-mounted panel 2, and the other end extends between the two fixing plates 4 of the annular frame 1.

[0031] See Figure 3 and Figure 4 The upper and lower fixed plates 4 have aligned fixing holes 41. The support rod 3 has corresponding connecting holes 31 on both sides, which are aligned with and identical to the fixing holes 41. A pin 5 passes through the fixing holes 41 and the connecting holes 31 to connect and fix the support rod 3 to the first wall-mounted plate 2 and to the annular frame 1. In use, the tower crane transmits force to the first wall-mounted plate 2 through the support rod 3, dispersing the force across the building. Simultaneously, the connecting rod 22 transmits force to the second wall-mounted plate 21, enhancing the building's support capacity for the tower crane.

[0032] In other embodiments, to reduce the possibility of the support rod 3 sliding up and down during use, the outer peripheral sidewall of the support rod 3 can contact each other with the upper and lower fixing plates 4 respectively. However, at this time, there is a certain friction between the support rod 3 and the fixing plate 4, and displacement needs to be achieved by tapping the support rod 3 during installation. At this time, the alignment of the connecting hole 31 and the fixing hole 41 is more difficult.

[0033] Therefore, in this embodiment, there is a gap between the outer periphery of the support rod 3 and the upper and lower fixing plates 4, which facilitates the installation of the support rod 3 and reduces the difficulty of aligning the fixing hole 41 and the connecting hole 31.

[0034] Two sets of mounting grooves 51 are symmetrically formed on the outer periphery of the pin 5, with each set of mounting grooves 51 located between the support rod 3 and a fixing plate 4. There are multiple mounting grooves 51 in each set, spaced apart circumferentially. In this embodiment, there are two mounting grooves 51 in each set.

[0035] The wall-mounted structure also includes fixing blocks 52. There are multiple sets of fixing blocks 52. Each set of fixing blocks 52 corresponds to a mounting groove 51. There are two fixing blocks 52 in each set, which are arranged symmetrically up and down. The two fixing blocks 52 in the same set slide up and down in the mounting groove 51 respectively.

[0036] See Figure 5 and Figure 6 Guide blocks are fixed to the side walls of the two fixed blocks 52 in the same group, and guide grooves 511 are formed in the wall of the mounting groove 51. The extension direction of the guide grooves 511 is parallel to the central axis of the pin 5. The guide blocks slide in the guide grooves 511 to guide the sliding trajectory of the fixed blocks 52 and limit the position of the fixed blocks 52. A support spring 512 is installed in the guide groove 511. The support spring 512 supports the guide blocks, so that when the weight of the guide blocks presses down on the support spring 512, the two fixed blocks 52 in the same group can be in the middle position of the mounting groove 51. In other embodiments, guide blocks and support springs 512 may not be provided. In this case, in the initial state, the drive block 65 abuts against the pushing surface 522 of the two fixed blocks 52 in the same group, so that the fixed blocks 52 clamp the drive block 65, thereby positioning the fixed blocks 52.

[0037] See Figure 4 and Figure 6 Each of the two fixed blocks 52 in the same group has an abutment plate 521 on its opposite side. The abutment plate 521 is fixed with a slider of "T" shape. The fixed block 52 has a sliding groove of "T" shape. The sliding groove extends through the opening of the mounting groove 51 to the outside of the fixed block 52. The slider slides in the sliding groove, so that the abutment plate 521 can slide on the fixed block 52 in the direction of the opening of the mounting groove 51.

[0038] The wall-mounted structure also includes a drive shaft 53 and a drive assembly. The drive shaft 53 is rotatably connected to the pin 5 and is coaxially arranged. At the same time, the drive shaft 53 and the pin 5 are slidably connected vertically. One end of the drive shaft 53 protrudes out of the pin 5, and in use, the end of the drive shaft 53 protruding from the pin 5 is positioned above.

[0039] The drive assembly is located on the pin 5 and includes a drive sleeve 61, a power sleeve 62, a power block 63, a push block 64, a drive block 65, a drive rope 6, and a tension spring 66. Tension springs 66 are installed in the slide grooves in a one-to-one correspondence. One end of the tension spring 66 is fixed to the abutment plate 521, and the other end is fixed to the side wall of the slide groove away from the opening of the mounting groove 51. When the tension spring 66 is released elastically, it pulls the abutment plate 521 to slide into the slide groove.

[0040] The drive rope 6 slides through two fixed blocks 52 in the same group, with both ends of the drive rope 6 fixed to the abutment plate 521. When the two fixed blocks 52 move away from each other, the drive rope 6 pulls the abutment plate 521 to slide out of the mounting groove 51, allowing the abutment plate 521 to protrude out of the mounting groove 51. At this time, the tension spring 66 enters an elastic tension state. As the two fixed blocks 52 continue to move away from each other, until the abutment plate 521 abuts against the fixed plate 4 and the support rod 3 on opposite sides, the pin 5 is restricted from moving up and down. When the tension spring 66 releases and causes the abutment plate 521 to slide into the groove, the abutment plate 521 pulls the drive rope 6, causing the two fixed blocks 52 in the same group to move closer to each other.

[0041] There are multiple push blocks 64, and each group of push blocks 64 corresponds to a group of fixed blocks 52. The push blocks 64 slide within the pin 5. The sliding trajectory of the push blocks 64 is perpendicular to the central axis of the pin 5, and the sliding trajectory of the push blocks 64 is located between two fixed blocks 52 in the same group.

[0042] Two fixed blocks 52 in the same group are inclined on the side away from the opening of the mounting groove 51, forming opposing pushing surfaces 522. When the pushing block 64 slides towards the opening of the mounting groove 51, the pushing block 64 slides on the pushing surface 522, at which time the pushing block 64 pushes the two fixed blocks 52 in the same group away from each other. When the pushing block 64 moves away from the pushing surface 522, the two fixed blocks 52 in the same group move closer to each other.

[0043] The drive sleeve 61 is a square sleeve structure and is fitted onto the outer periphery of the drive shaft 53. The central axis of the drive sleeve 61 coincides with the central axis of the pin 5. The drive sleeve 61 and the drive shaft 53 are slidably connected vertically, and the drive sleeve 61 slides vertically within the pin 5. The drive block 65 slides vertically within the pin 5 and corresponds one-to-one with the push block 64. The drive block 65 is fixed on the outer periphery of the drive sleeve 61. The side of the push block 64 closest to the drive sleeve 61 has an inclined transmission surface 641, which faces the drive block 65. When the drive sleeve 61 moves downward, the drive block 65 slides on the transmission surface 641, at which time the drive block 65 pushes the push block 64 toward the opening of the mounting groove 51.

[0044] The power sleeve 62 is threadedly connected to the pin 5 and located directly above the drive sleeve 61. The power sleeve 62 slides up and down on the outer periphery of the drive shaft 53 and is coaxially arranged. The power sleeve 62 and the drive shaft 53 are rotatably connected, and the power sleeve 62 and the drive shaft 53 can be linked together. A power block 63 is fixedly connected to the outer periphery of the power sleeve 62. When the drive shaft 53 rotates forward, the power sleeve 62 drives the power block 63 to move downward. At this time, the power block 63 abuts against the top of the drive sleeve 61 and slides on the top of the drive sleeve 61. At this time, the power block 63 drives the drive block 65 to slide downward. When the drive shaft 53 rotates in the reverse direction, the power block 63 moves away from the drive sleeve 61. At this time, the two fixed blocks 52 in the same group move closer to each other, and the push block 64 pushes the drive block 65 to move upward, while driving the drive sleeve 61 to move upward. In order to facilitate the actuation of the drive shaft 53, an actuation groove 531 is provided on the outer periphery of the drive shaft 53. The actuation groove 531 is located outside the pin 5. When in use, insert the rod or column tool into the actuation slot 531, and then you can easily rotate the drive shaft 53.

[0045] To facilitate the passage of the pin 5 through the fixing hole 41 and the connecting hole 31, the diameter of the pin 5 is smaller than the diameters of the fixing hole 41 and the connecting hole 31. Simultaneously, to facilitate the transmission of force from the support rod 3 to the fixing plate 4 when the pin 5 has a smaller diameter, the pin 5 is equipped with a support plate 58. By driving the support plate 58 to move away from the central axis of the pin 5 until it abuts against the walls of the connecting hole 31 and the fixing hole 41, the transmission of force is facilitated.

[0046] See Figure 7 and Figure 8 The pin 5 has multiple receiving grooves 54 formed along its circumference, and the support plate 58 corresponds to each receiving groove 54. The support plate 58 has an arc-shaped plate structure and slides within the receiving groove 54. In this embodiment, there are two receiving grooves 54, and each receiving groove 54 is located between two adjacent mounting grooves 51 in the circumferential direction.

[0047] The pin 5 has multiple supporting columns 55 that slide, and the supporting columns 55 protrude into the receiving groove 54. Each supporting column 55 corresponds to a supporting plate 58, and the end of the supporting column 55 is fixed in the middle position of the supporting plate 58. The sliding trajectory of the supporting column 55 is perpendicular to the central axis of the pin 5.

[0048] See Figure 5 and Figure 6 The drive sleeve 61 includes an upper sleeve 611 and a lower sleeve 612. The upper sleeve 611 and the lower sleeve 612 are coaxially arranged, and a fixing post 613 is fixedly connected between the upper sleeve 611 and the lower sleeve 612. The upper sleeve 611 and the lower sleeve 612 are linked through the fixing post 613.

[0049] The pin 5 is equipped with a mounting ring 614 that slides up and down on the fixed post 613. The mounting ring 614 is coaxially arranged with the drive sleeve 61. A transmission sleeve 532 is rotatably connected to the outer circumference of the drive shaft 53. The transmission sleeve 532 is coaxially arranged with the drive shaft 53 and is threadedly connected to the mounting ring 614. When the transmission sleeve 532 moves forward, the mounting ring 614 moves downward; when the transmission sleeve 532 moves in reverse, the mounting ring 614 moves upward.

[0050] See Figure 7 and Figure 8 A transmission block 615 is fixedly connected to the outer periphery of the mounting ring 614. The transmission block 615 is inclined and has a sliding surface 616 facing the support column 55. When the mounting ring 614 moves downward, the support column 55 slides on the sliding surface 616. At this time, the transmission block 615 pushes the support column 55 to slide outward toward the pin 5 until the support plate 58 abuts against the connecting hole 31 (the connecting hole 31 is in...). Figure 4 (as indicated by the bid) and fixing hole 41 (fixing hole 41 is in) Figure 4 When the hole wall is marked, the mounting ring 614 is restricted from moving downwards.

[0051] A limiting block 551 is fixedly connected to the side wall of the support column 55. A limiting groove 56 is formed inside the pin 5, and the extending direction of the limiting groove 56 is perpendicular to the central axis of the pin 5. The limiting block 551 slides within the limiting groove 56. The pin 5 is provided with an elastic reset element, which is a reset spring 57. The reset spring 57 is installed in the limiting groove 56, with one end abutting against the side of the limiting block 551 near the receiving groove 54, and the other end abutting against the groove wall of the limiting groove 56. When the transmission block 615 moves away from the support column 55, the reset spring 57 pushes the limiting block 551, causing the support column 55 to slide into the pin 5, which in turn drives the support plate 58 to slide into the receiving groove 54.

[0052] The pin 5 is equipped with a control component, which controls the transmission sleeve 532 and the drive shaft 53 to enter a linkage state, or controls the power sleeve 62 and the drive shaft 53 to enter a linkage state.

[0053] See Figure 5 and Figure 6 The control components include a control column 7, an upper push block 71, a lower push block 72, an upper linkage block 73, a lower linkage block 74, an upper spring 75, and a lower spring 76. The control post 7 slides up and down on the drive shaft 53 and is coaxially arranged. The control post 7 protrudes outside the drive shaft 53. At this time, the control post 7 is also located outside the pin 5.

[0054] The upper linkage block 73 slides along the central axis of the pin 5 on the drive shaft 53, and the inner peripheral sidewall of the power sleeve 62 forms a first slot 621. The upper linkage block 73 can be inserted into the first slot 621, at which time the power sleeve 62 and the drive shaft 53 are linked. When the drive shaft 53 rotates, the power sleeve 62 rotates with the drive shaft 53.

[0055] The push block 71 is fixed to the outer periphery of the control post 7 and slides up and down within the drive shaft 53. The push block 71 is inclined to form an upward push surface 711. When the control post 7 moves downward, the push block 71 moves downward. At this time, the upper linkage block 73 slides on the upward push surface 711. The push block 71 pushes the upper linkage block 73 into the first slot 621 until the end of the push block 71 away from the control post 7 abuts against the end of the upper linkage block 73 near the control post 7. When the upper linkage block 73 is not aligned with the first slot 621, the power sleeve 62 rotates relative to the drive shaft 53 and keeps the control post 7 in a downward movement state until the upper linkage block 73 is aligned with the first slot 621 and then the upper linkage block 73 is inserted into the first slot 621.

[0056] A stop block is fixed to the side wall of the push block 71, and a groove for the stop block to slide is formed inside the drive shaft 53. An upper spring 75 is installed in the groove, with one end of the upper spring 75 abutting against the side of the stop block away from the first slot 621, and the other end abutting against the groove wall. When the push block 71 moves away from the upper linkage block 73 and the upper linkage block 73 is aligned with the first slot 621, the upper spring 75 pushes the upper linkage block 73 to slide out of the first slot 621.

[0057] A linkage groove 534 is formed on the inner peripheral side wall of the transmission sleeve 532. The extension direction of the linkage groove 534 is perpendicular to the central axis of the pin 5. The lower linkage block 74 slides in the linkage groove 534.

[0058] A second slot 533 is formed on the outer periphery of the drive shaft 53 for the lower linkage block 74 to be inserted and slide up and down. The extension direction of the second slot 533 is parallel to the central axis of the pin 5. The lower spring 76 is installed in the linkage groove 534. When the lower linkage block 74 is aligned with the second slot 533, the lower spring 76 pushes the lower linkage block 74 into the second slot 533 until the end of the lower push block 72 away from the control pin 7 abuts against the end of the lower linkage block 74 near the control pin 7. At this time, the transmission sleeve 532 is linked with the drive shaft 53. When the drive shaft 53 rotates, the transmission sleeve 532 rotates with the drive shaft 53.

[0059] The push block 72 is fixed to the outer periphery of the control post 7, and the push block 72 is inclined to form a push surface 721. When the control post 7 slides downward, the lower linkage block 74 slides on the push surface 721. At this time, the push block 72 pushes the lower linkage block 74 out of the second slot 533, and the transmission sleeve 532 and the drive shaft 53 enter a state of relative rotation. At the same time, the upper linkage block 73 is inserted into the first slot 621, and the power sleeve 62 and the drive shaft 53 are in a state of linkage. When the control post 7 moves upward, the upper push block 71 moves away from the upper linkage block 73, and the push block 72 moves away from the lower linkage block 74. At this time, the power sleeve 62 and the drive shaft 53 enter a state of relative rotation, and the transmission sleeve 532 and the drive shaft 53 enter a state of linkage.

[0060] The implementation principle of a tower crane wall-mounted structure in this application embodiment is as follows: Place the two ends of the support rod 3 between the two fixing plates 4 of the first wall-mounted plate 2 and between the upper and lower fixing plates 4 of the annular frame 1, respectively, so that the fixing hole 41 is aligned with the connecting hole 31. Then, pass the pin 5 through the fixing hole 41 and the connecting hole 31, so that the drive shaft 53 is positioned at the top. Then rotate the drive shaft 53 until the abutting plate 521 abuts against the fixing plate 4 and the support rod 3. Then, press down on the control column 7 while rotating the drive shaft 53, so that the support plate 58 slides out of the receiving groove 54 until it abuts against the wall of the fixing hole 41 and the connecting hole 31.

[0061] On the other hand, this application discloses a construction method for a tower crane wall-mounted structure, including the following steps: Step 1: Pre-installation of wall-mounted components; Step 2: Fix the ring frame 1 to the outer periphery of the tower crane; Step 3: Place the support rod 3 so that the fixing hole 41 is aligned with the connecting hole 31; Step 4: Pass the pin 5 through the fixing hole 41 and the connecting hole 31, and rotate the drive shaft 53 in the forward direction so that the drive assembly drives the fixing blocks 52 in the same group to move away from each other until the abutting plate 521 abuts the support rod 3 and the fixing plate 4 respectively.

[0062] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
