Description

Technical Field

[0001] This invention relates to the field of building equipment technology, specifically to a precise positioning device for hoisting embedded parts. Background Technology

[0002] As green and environmentally friendly concepts continue to penetrate the construction industry, green, energy-saving, and environmentally friendly construction has become the main theme of engineering projects. In reality, some projects involve large quantities of work and complex structures, with a large number of embedded parts installed, many of which are large in size and weight. Therefore, achieving precise positioning of embedded parts in locations where tower cranes cannot reach or where tower crane operation is inconvenient due to the complexity of the building components presents significant challenges.

[0003] In existing technologies, tower cranes are used to lift embedded parts to the vicinity of the installation location. However, during the transportation process, the embedded parts cannot be fixed and often sway, increasing safety hazards. If a clamping component is added, a separate drive device needs to be set for the clamping component, which not only increases the size of the equipment but also increases the manufacturing cost.

[0004] Precise and secure installation of embedded parts cannot be achieved, and there are safety risks when the embedded parts are heavy.

[0005] To address this, we propose a precise positioning device for the hoisting of embedded parts. Summary of the Invention

[0006] To overcome the shortcomings of existing technologies, the present invention provides the following technical solution: a precise positioning device for hoisting embedded parts, comprising a bottom support, a movable wheel at the bottom of the bottom support, a support rod fixedly installed at the top of the bottom support, a top support fixedly installed at the top of the support rod, a lifting motor fixedly installed at the top of the bottom support, a winding drum fixedly installed at the output end of the lifting motor, a lifting steel cable wound on the winding drum, a connecting ring fixedly installed at the other end of the lifting steel cable, a lifting assembly movably connected to the lifting steel cable through the connecting ring, and a clamping assembly at the bottom of the lifting assembly.

[0007] Preferably, the lifting assembly includes a connector movably connected to the connecting ring, a lifting frame is provided at the bottom of the connector, an mounting plate is fixedly installed at the middle of the bottom of the lifting frame, a hook is rotatably connected at the middle of the bottom of the mounting plate, and the clamping assembly is fixedly installed to the bottom and both sides of the lifting frame.

[0008] Preferably, a lifting ring is sleeved through the inside of the connecting ring, the middle part of the top of the connecting member is fixedly installed to the lifting ring by bolts, a reversing wheel assembly is fixedly installed on the top of the top bracket, and the middle part of the lifting cable is in rolling contact with the rollers in the reversing wheel assembly.

[0009] Preferably, the clamping assembly includes a guide threaded rod fixedly installed at the center of the top of the bottom bracket, and a rotating frame fixedly installed on both sides of the lifting frame. The top of the guide threaded rod is fixedly installed at the bottom of the top bracket. A threaded sleeve is rotatably connected to the center of the rotating frame. The threaded sleeve is threadedly connected to the guide threaded rod. A drive gear located above the rotating frame is fixedly installed on the outer circumferential surface of the guide threaded rod.

[0010] Preferably, the rotating frame is rotatably connected to a rotating shaft located on one side of the threaded sleeve. A driven gear is fixedly installed on the rotating shaft above the rotating frame. The rotating shaft passes through both sides of the lifting frame. A tightening wheel is fixedly installed on the rotating shaft below the lifting frame. The driven gear meshes with the driving gear.

[0011] Preferably, the lifting frame is fixedly connected to mounting brackets located on both sides of the rotating frame, and a guide rod is fixedly installed between the two mounting brackets. The guide rod is rotatably connected to a clamping plate.

[0012] Preferably, a tightening rope is fixedly connected to the outer circumferential surface of the tightening wheel, and the other end of the tightening rope is fixedly connected to the side of the clamping plate. Anti-slip pads are adhered to the opposite surfaces of the two clamping plates.

[0013] Preferably, a clamping spring is sleeved on the outside of the guide rod, one end of the clamping spring abuts against the side of the mounting bracket, and the other end of the clamping spring abuts against the side of the clamping plate.

[0014] Preferably, the lifting frame has two parallel channel steels symmetrically arranged inside, and the two ends of the connector are respectively movably connected to the middle of the two channel steels by fixing pins.

[0015] Preferably, the rotating frame consists of two pieces as a group, and the rotating frame of the group is respectively fitted to the top and bottom of the lifting frame. The diameter of the threaded sleeve located between the two rotating frames is larger than the diameter of the rest. The top of the guide threaded rod is fixedly installed at the middle of both sides of the top bracket, and the guide threaded rod is provided with a scale on its outside.

[0016] A method for using a precise positioning device for hoisting embedded parts involves installing the embedded part with a hook, starting a lifting motor, which drives a winding drum to rotate and continuously wind up the lifting cable. This causes the lifting frame, connected to the lifting cable via a connecting ring, to rise continuously, thereby lifting the embedded part through a lifting ring. The lifting assembly is continuously lifted under the drive of the lifting motor, causing the threaded sleeve, which is threadedly connected to the guide threaded rod, to rotate. As the threaded sleeve rotates, the driving gear and driven gear drive the rotating shaft to rotate, which in turn causes the tightening wheel to rotate. The tightening rope loosens as the tightening wheel rotates, causing the two clamping plates to move closer together under the action of clamping springs. This clamping plates then fix the embedded part in place, preventing it from shaking during movement.

[0017] Compared with the prior art, the present invention provides a precise positioning device for the hoisting of embedded parts, which has the following beneficial effects:

[0018] 1. This type of precise positioning device for hoisting embedded parts involves setting up a lifting assembly to install the embedded part with a hook, starting the lifting motor, which drives the winding drum to rotate and continuously wind up the lifting steel cable. This causes the lifting frame, connected to the lifting steel cable via a connecting ring, to rise continuously, thereby lifting the embedded part through the lifting ring. The embedded part is then clamped by a clamping assembly to prevent it from shaking, and finally moved by the moving wheels to place the embedded part in a suitable position.

[0019] 2. This embedded part hoisting precision positioning device, by setting up a clamping assembly, when the lifting assembly is continuously lifted under the drive of the lifting motor, causes the threaded sleeve connected to the guide threaded rod to rotate. As the threaded sleeve rotates, the rotating shaft is driven to rotate through the driving gear and the driven gear, which in turn causes the tightening wheel to rotate. The tightening rope is relaxed as the tightening wheel rotates, causing the two clamping plates to move closer to each other under the action of the clamping spring, thereby fixing the embedded part and preventing the embedded part from shaking during movement. This application can realize the lifting and automatic clamping of the embedded part with a set of driving equipment, which not only effectively reduces the size of the equipment, but also reduces the manufacturing cost.

[0020] 3. This kind of embedded part hoisting and positioning device, by setting a guide threaded rod and a threaded sleeve, after the embedded part is lifted and transported to the appropriate position by the lifting component, the height of the lifting frame is controlled by the lifting motor, and the height of the embedded part is determined by the scale of the guide threaded rod, and the clamping component is used to prevent shaking during concrete pouring.

[0032] In one embodiment of the present invention, the lifting assembly 8 includes a connector 81 movably connected to the connecting ring 11. A lifting frame 82 is provided at the bottom of the connector 81. An installation plate 83 is fixedly installed at the middle of the bottom of the lifting frame 82. A hook 84 is rotatably connected to the middle of the bottom of the installation plate 83. A clamping assembly 9 is fixedly installed at the bottom and both sides of the lifting frame 82. By setting up the lifting assembly 8, the embedded part is installed with the hook 84. The lifting motor 5 is started, and the lifting motor 5 drives the winding drum 6 to rotate, continuously winding the lifting steel cable 7, so that the lifting frame 82 connected to the lifting steel cable 7 through the connecting ring 11 continuously rises. Then, the embedded part is lifted by the lifting ring and clamped by the clamping assembly 9 to prevent the embedded part from shaking. Then, it is moved by the moving wheel 2 to place the embedded part in a suitable position.

[0033] In one embodiment of the present invention, a lifting ring is sleeved through the inside of the connecting ring 11, and the middle part of the top of the connecting piece 81 is fixedly installed to the lifting ring by bolts. A deflector wheel set 10 is fixedly installed on the top of the top bracket 4, and the middle part of the lifting cable 7 is in rolling contact with the roller in the deflector wheel set 10.

[0034] In one embodiment of the present invention, the clamping assembly 9 includes a guide threaded rod 91 fixedly installed at the center of the top of the bottom bracket 1, and a rotating frame 92 fixedly installed on both sides of the lifting frame 82. The top of the guide threaded rod 91 is fixedly installed at the bottom of the top bracket 4. A threaded sleeve 93 is rotatably connected to the center of the rotating frame 92. The threaded sleeve 93 is threadedly connected to the guide threaded rod 91. A drive gear 94 located above the rotating frame 92 is fixedly installed on the outer circumferential surface of the guide threaded rod 91.

[0035] In one embodiment of the present invention, the rotating frame 92 is rotatably connected to a rotating shaft 96 located on one side of the threaded sleeve 93. The rotating shaft 96 is fixedly mounted with a driven gear 95 located above the rotating frame 92. The rotating shaft 96 passes through both sides of the lifting frame 82. The rotating shaft 96 is fixedly mounted with a tightening wheel 97 located below the lifting frame 82. The driven gear 95 meshes with the driving gear 94.

[0036] In one embodiment of the present invention, mounting brackets 99 located on both sides of the rotating frame 92 are fixedly connected to the two sides of the lifting frame 82, and a guide rod 910 is fixedly installed between the two mounting brackets 99. The guide rod 910 is rotatably connected to the clamping plate 911 through it.

[0037] In one embodiment of the present invention, a tightening rope 98 is fixedly connected to the outer peripheral surface of the tightening wheel 97, and the other end of the tightening rope 98 is fixedly connected to the side of the clamping plate 911. Anti-slip pads 913 are bonded to the opposite surfaces of the two clamping plates 911. By setting the clamping assembly 9, when the lifting assembly 8 is continuously lifted under the drive of the lifting motor 5, the threaded sleeve 93 threadedly connected to the guide threaded rod 91 rotates. As the threaded sleeve 93 rotates, the rotating shaft 96 is driven to rotate through the driving gear 94 and the driven gear 95, thereby causing the tightening wheel 97 to rotate. The tightening rope 98 relaxes as the tightening wheel 97 rotates, causing the two clamping plates 911 to move closer to each other under the action of the clamping spring 912, thereby fixing the embedded part in place and preventing the embedded part from shaking during movement.

[0038] In one embodiment of the present invention, a clamping spring 912 is sleeved on the outside of the guide rod 910. One end of the clamping spring 912 abuts against the side of the mounting bracket 99, and the other end of the clamping spring 912 abuts against the side of the clamping plate 911.

[0039] In one embodiment of the present invention, two parallel channel steels are symmetrically arranged inside the lifting frame 82, and the two ends of the connector 81 are movably connected to the middle of the two channel steels by fixing pins.

[0040] In one embodiment of the present invention, two rotating frames 92 are arranged as a group, and the group of rotating frames 92 is respectively attached to the top and bottom of the lifting frame 82. The diameter of the threaded sleeve 93 located between the two rotating frames 92 is larger than the diameter of the rest. The top of the guide threaded rod 91 is fixedly installed at the middle of both sides of the top bracket 4. The guide threaded rod 91 is provided with a scale on its outside. By setting the guide threaded rod 91 and the threaded sleeve 93, after the embedded part is lifted and transported to the appropriate position by the lifting assembly 8, the height of the lifting frame 82 is controlled by the lifting motor 5, and the height of the embedded part is determined by the scale of the guide threaded rod 91. The clamping assembly 9 is used to prevent shaking when pouring concrete.

[0041] It should be noted that during use, the embedded part is installed with the hook 84, the lifting motor 5 is started, the lifting motor 5 drives the winding drum 6 to rotate, continuously winding the lifting steel cable 7, so that the lifting frame 82 connected to the lifting steel cable 7 through the connecting ring 11 continuously rises, and then the embedded part is lifted by the lifting ring. The lifting assembly 8 is continuously lifted under the drive of the lifting motor 5, which causes the threaded sleeve 93 threadedly connected to the guide threaded rod 91 to rotate. As the threaded sleeve 93 rotates, the driving gear 94 and the driven gear 95 drive the rotating shaft 96 to rotate, which in turn causes the tightening wheel 97 to rotate. The tightening rope 98 is relaxed as the tightening wheel 97 rotates, so that the two clamping plates 911 move closer to each other under the action of the clamping spring 912, thereby fixing the embedded part and preventing the embedded part from shaking during movement.
