Description

Technical Field

[0001] This application relates to the field of ceiling installation technology, and in particular, to an electric hanging point device applicable to a steel structure conversion layer. Background Art

[0002] For the overall aesthetics of a building, ceilings are often installed in many large spaces. When the internal space of the ceiling is more than 3m, a conversion layer needs to be set up. Multiple hanging points are arranged on the conversion layer to provide support for the ceiling through these multiple hanging points, enhancing the structural strength of the ceiling.

[0003] Currently, for the steel structure conversion layer of the ceiling, screws are usually used as suspenders. The suspenders are passed through the ceiling, and then the support seats are screwed onto the suspenders. The ceiling can be supported by the support seats. However, during the construction process, the support height of each hanging point for the ceiling usually needs to be adjusted to level the ceiling. Then, construction workers need to turn the support seats on each suspender. Since the gravity of the ceiling acts on the support seats on the suspenders, it is very laborious for construction workers to turn the support seats on the suspenders, resulting in the problem that it is inconvenient for construction workers to adjust the flatness of the ceiling. Utility Model Content

[0004] In order to improve the convenience of adjusting the ceiling by adjusting the hanging points of the steel structure conversion layer, this application provides an electric hanging point device applicable to a steel structure conversion layer.

[0005] The electric hanging point device applicable to a steel structure conversion layer provided by this application adopts the following technical solutions:

[0006] An electric hanging point device applicable to a steel structure conversion layer includes an electric hoist, a clamping mechanism, a hook, and a bearing mechanism. The clamping mechanism is arranged on the electric hoist and is used to clamp onto the steel structure conversion layer. The hook is hooked onto the hook under the electric hoist, and the bearing mechanism is arranged on the hook and is used to connect to the ceiling.

[0007] By adopting the above technical solutions, construction workers clamp the clamping mechanism onto the steel structure conversion layer, then hook the hook onto the hook under the electric hoist, control the hook under the electric hoist to lower, connect to the ceiling through the bearing mechanism, and then retract the hook under the electric hoist, and the ceiling can be hoisted conveniently and quickly. After hoisting the ceiling, construction workers control the release or retraction of the hook under the electric hoist to adjust the flatness of the ceiling, effectively improving the convenience of adjusting the ceiling by adjusting the hanging points of the steel structure conversion layer.

[0008] Optionally, the bearing mechanism includes a bearing sleeve and a limiting member. The bearing sleeve is arranged on the lifting hook. An opening for the main keel of the suspended ceiling to be inserted is formed on the side of the bearing sleeve. The limiting member is arranged on the bearing sleeve and is used for positioning the main keel of the suspended ceiling within the bearing sleeve.

[0009] By adopting the above technical solution, the construction worker controls the lowering of the lifting hook so that the side opening of the bearing sleeve is aligned with the main keel of the suspended ceiling. Then, the bearing sleeve is moved to be inserted into the main keel of the suspended ceiling, and the main keel of the suspended ceiling is positioned within the bearing sleeve through the limiting member, thus facilitating and firmly connecting with the suspended ceiling.

[0010] Optionally, the limiting member includes a limiting bolt. The limiting bolt is threadedly arranged on the bearing sleeve and penetrates through the side opening of the bearing sleeve.

[0011] By adopting the above technical solution, after the main keel of the suspended ceiling is inserted into the bearing sleeve, the construction worker rotates the limiting bolt so that the limiting bolt penetrates through the side opening of the bearing sleeve, and the limiting bolt can block the main keel of the suspended ceiling, improving the stability of the main keel of the suspended ceiling within the bearing sleeve.

[0012] Optionally, the clamping mechanism includes a connecting hook, clamping arms, and a control component. The connecting hook is hooked on the hook above the electric hoist. Two clamping arms are hinged on the connecting hook. The control component is arranged on the connecting hook and is used to drive the two clamping arms to approach or move away from each other.

[0013] By adopting the above technical solution, the construction worker drives the two clamping arms to approach each other through the control component. The two clamping arms can then clamp the steel structure conversion layer. Then, the hook above the electric hoist is hooked to the connecting hook, thus conveniently and quickly completing the installation of the electric hoist on the steel structure conversion layer. And by adjusting the two clamping arms to clamp the steel structure conversion layer at different positions, the position of the electric hoist can be adjusted.

[0014] Optionally, the control component includes a lead screw and a control block. The lead screw is rotatably arranged on the connecting hook. The control block is threadedly arranged on the lead screw. Control grooves are obliquely formed on both clamping arms, and the inclination directions of the two control grooves are opposite. The two ends of the control block are respectively slidably arranged in one control groove.

[0015] By adopting the above technical solution, the construction worker rotates the lead screw. The lead screw drives the control block to move. During the movement of the control block, it abuts against the side wall of the obliquely formed control groove, and thus can drive the two clamping arms to approach or move away from each other, effectively improving the convenience for the construction worker to control the two clamping arms.

[0016] Optionally, a locking mechanism for limiting the rotation of the screw rod is provided on the connecting hook, and the locking mechanism includes a ratchet, a pawl and a spring. The ratchet is coaxially arranged on the screw rod, the pawl is hingedly arranged on the connecting hook, and the spring is arranged on the connecting hook and connected to the pawl. The spring always has a tendency to drive the pawl to abut against the ratchet so that the ratchet can only rotate in the direction in which the screw rod drives the two clamping arms to approach each other.

[0017] By adopting the above technical solution, when the construction personnel rotate the screw rod in the direction of driving the two clamping arms toward each other, the screw rod drives the ratchet to rotate, and the ratchet wheel can push the pawl open, so that the ratchet wheel and the screw rod can rotate normally. After the two clamping arms are clamped on the steel structure conversion layer, the spring drives the pawl to abut against the ratchet wheel, and the pawl restricts the ratchet wheel from rotating in the direction of the screw rod driving the two clamping arms away from each other, so that the two clamping arms remain in a state of being clamped on the steel structure conversion layer, effectively improving the stability of the clamping arms clamped on the steel structure conversion layer.

[0018] Optionally, the connecting hook is provided with a shifting assembly for driving the pawl away from the ratchet wheel, the shifting assembly includes a shifting rod and a shifting block, the shifting rod is rotatably arranged on the connecting hook, and the shifting block is eccentrically arranged on the shifting rod and used to abut against the pawl.

[0019] By adopting the above technical solution, the construction personnel rotate the lever, which drives the shift block to rotate, and the shift block pushes the pawl away from the ratchet. At this time, the construction personnel can rotate the screw rod in the direction of driving the two clamping arms away from each other, thereby improving the convenience of the construction personnel to remove the restriction on the rotation of the screw rod.

[0020] Optionally, a rubber pad is provided on one side of the two clamping arms that are close to each other.

[0021] By adopting the above technical solution, when the two clamping arms clamp the steel structure conversion layer, the rubber pad is blocked between the clamping arms and the steel structure conversion layer, thereby improving the stability of the clamping arms in clamping the steel structure conversion layer.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. After the ceiling is hoisted, the construction personnel can adjust the flatness of the ceiling by controlling the hook under the electric hoist to release or retract it, which effectively improves the convenience of adjusting the hanging point of the steel structure transfer layer and adjusting the ceiling;

[0024] 2. Move the bearing sleeve to insert into the main keel of the ceiling, and then position the main keel of the ceiling in the bearing sleeve through the limiter, so that it can be conveniently and firmly connected to the ceiling;

DETAILED DESCRIPTION

[0031] The following is combined with Figures 1-4 This application is described in further detail.

[0032] The embodiment of the present application discloses an electric lifting point device suitable for a steel structure transfer layer.

[0033] Reference Figure 1 The electric lifting point device suitable for the steel structure transfer layer includes an electric hoist 1, a clamping mechanism 2, a hook 3 and a bearing mechanism 4.

[0034] Reference Figure 1 , Figure 2, the clamping mechanism 2 is installed on the electric hoist 1. The clamping mechanism 2 is used to clamp onto the steel structure conversion layer. The clamping mechanism 2 includes a connecting hook 21, clamping arms 22, and a control component 23. The connecting hook 21 is hooked onto the hook above the electric hoist 1. In this embodiment, the connecting hook 21 is an anti-disengagement hook to enhance the stability of the connecting hook 21 being hooked onto the hook above the electric hoist 1. Two clamping arms 22 are coaxially hinged and installed on the connecting hook 21. In this embodiment, both of the two clamping arms 22 extend towards the end adjacent to the other clamping arm 22, so that when the two clamping arms 22 clamp the steel structure conversion layer, they can embrace the steel structure conversion layer, increasing the stability of clamping the steel structure conversion layer. The control component 23 is installed on the connecting hook 21 and is used to drive the two clamping arms 22 to approach or move away from each other. The control component 23 includes a lead screw 231 and a control block 232. The lead screw 231 is rotatably installed on the connecting hook 21, and the control block 232 is threadedly installed on the lead screw 231. Control grooves 221 are formed on both of the two clamping arms 22. The control grooves 221 are inclined, and the inclination directions of the two control grooves 221 are opposite. The two ends of the control block 232 respectively slide and abut against the side walls of the two control grooves 221.

[0035] The construction worker moves the connecting hook 21 so that the two clamping arms 22 are respectively located on both sides of the steel beam of the steel structure conversion layer. Then, the lead screw 231 is rotated. The lead screw 231 drives the control block 232 to move. The control block 232 presses against the side wall of the control groove 221, so that the two clamping arms 22 can approach each other and clamp onto the steel beam of the steel structure conversion layer, facilitating the construction worker to control the two clamping arms 22. Then, the construction worker hooks the hook above the electric hoist 1 onto the connecting hook 21, and the positioning installation of the electric hoist 1 on the steel structure conversion layer can be completed. The entire installation process is convenient and fast. Moreover, the construction worker rotates the lead screw 231 forward and backward to make the two clamping arms 22 move away from each other, and then adjusts the position of the steel structure conversion layer clamped by the two clamping arms 22, so as to adjust the position of the positioning electric hoist 1, effectively improving the convenience for the construction worker to adjust the position of the lifting point.

[0036] Refer to Figure 2 , rubber pads are covered on the sides of the two clamping arms 22 that approach each other. Through the characteristics of high elasticity and high friction of the rubber pads, buffering is provided for the clamping arms 22 and the steel beam of the steel structure conversion layer, enhancing the stability when the clamping arms 22 clamp the steel beam of the steel structure conversion layer.

[0037] Refer to Figure 2 、 Figure 3A locking mechanism 5 is installed on the connecting hook 21, and the locking mechanism 5 is used to limit the rotation of the screw rod 231. The locking mechanism 5 includes a ratchet 51, a pawl 52 and a spring 53. The ratchet 51 is coaxially installed on the screw rod 231, and the pawl 52 is hingedly installed on the connecting hook 21. The pawl 52 abuts against the ratchet 51 so that the ratchet 51 can only rotate in the direction toward the screw rod 231 to drive the two clamping arms 22 to approach each other. One end of the spring 53 is installed on the connecting hook 21, and the other end of the spring 53 is installed on the pawl 52. The spring 53 always has a tendency to drive the pawl 52 to abut against the ratchet 51.

[0038] When the construction personnel rotate the screw rod 231 to drive the two clamping arms 22 towards each other, the ratchet 51 pushes the pawl 52 away, and the ratchet 51 can rotate normally. After the two clamping arms 22 are driven to clamp on the steel beam of the steel structure conversion layer, the spring 53 drives the pawl 52 to abut against the ratchet 51. The pawl 52 restricts the ratchet 51 from rotating in the direction in which the screw rod 231 drives the two clamping arms 22 away from each other, thereby restricting the rotation of the screw rod 231, so that the two clamping arms 22 maintain a state of clamping the steel beam of the steel structure conversion layer, effectively improving the stability of the clamping arms 22 clamping the steel beam of the steel structure conversion layer.

[0039] Reference Figure 2 , Figure 3 A toggle assembly 6 is installed on the connecting hook 21, and the toggle assembly 6 is used to drive the pawl 52 away from the ratchet 51. The toggle assembly 6 includes a toggle rod 61 and a toggle block 62. The toggle rod 61 is rotatably installed on the connecting hook 21, and the toggle block 62 is eccentrically installed on the toggle rod 61. The toggle block 62 is used to abut against the pawl 52.

[0040] When it is necessary to drive the two clamping arms 22 away from each other, the construction personnel first rotate the lever 61, and the lever 61 drives the eccentrically installed shift block 62 to rotate, and the shift block 62 can shift the pawl 52 in the direction away from the ratchet 51. At this time, the pawl 52 contacts the restriction on the rotation of the ratchet 51, and the construction personnel can rotate the screw rod 231 to drive the two clamping arms 22 away from each other, which effectively improves the convenience of the construction personnel to remove the restriction on the rotation of the screw rod 231.

[0041] Reference Figure 1 , Figure 4, the lifting hook 3 is hooked on the hook under the electric hoist 1. In this embodiment, the lifting hook 3 is also an anti-disengagement hook; the bearing mechanism 4 is installed on the lifting hook 3, and the bearing mechanism 4 is used to connect with the suspended ceiling. The bearing mechanism 4 includes a bearing sleeve 41 and a limiting member 42. The bearing sleeve 41 is installed on the lifting hook 3, and an opening for the main keel of the suspended ceiling to be inserted is provided on the side of the bearing sleeve 41; the limiting member 42 is installed on the bearing sleeve 41, and the limiting member 42 is used to position the main keel of the suspended ceiling in the bearing sleeve 41. The limiting member 42 includes a limiting bolt 421, and the limiting bolt 421 is threadedly installed on the side wall of the bearing sleeve 41 near the opening side, and the limiting bolt 421 penetrates into the bearing sleeve 41 to block the side opening of the bearing sleeve 41.

[0042] After positioning the electric hoist 1, the construction worker hooks the lifting hook 3 to the hook under the electric hoist 1, and then lowers the hook of the electric hoist 1 so that the side opening of the bearing sleeve 41 is aligned with the main keel of the suspended ceiling. Then, the main keel of the suspended ceiling is inserted into the bearing sleeve 41 through the side opening of the bearing sleeve 41. Then, turn the limiting bolt 421 so that the limiting bolt 421 penetrates into the bearing sleeve 41. The limiting bolt 421 can position the main keel of the suspended ceiling in the bearing sleeve 41, prevent the main keel of the suspended ceiling from sliding out of the bearing sleeve 41, and improve the stability of the main keel of the suspended ceiling in the bearing sleeve 41. Then, the construction worker controls the recovery of the hook under the electric hoist 1, and the suspended ceiling can be lifted and hoisted conveniently and quickly.

[0043] The implementation principle of the electric hanging point device applicable to the steel structure conversion layer in the embodiment of the present application is as follows: The construction worker clamps the clamping mechanism 2 to the steel beam of the steel structure conversion layer according to the set position of the hanging point, and then hooks the hook above the electric hoist 1 to the connecting hook 21 to complete the fixed-point installation of the electric hoist 1. Then, the construction worker hooks the lifting hook 3 to the hook under the electric hoist 1, and then lowers the hook under the electric hoist 1 so that the side opening of the bearing sleeve 41 is aligned with the main keel of the suspended ceiling. The main keel of the suspended ceiling is inserted into the bearing sleeve 41, and the limiting bolt 421 is turned to limit the main keel of the suspended ceiling in the bearing sleeve 41. Then, the hook under the electric hoist 1 can be retracted to lift and hoist the suspended ceiling. Subsequently, the construction worker directly controls the telescoping of the hook under the electric hoist 1 to adjust the flatness of the suspended ceiling, effectively improving the convenience of adjusting the hanging point of the steel structure conversion layer to adjust the suspended ceiling.

[0044] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
