Description

Technical Field

[0001] The utility model relates to the technical field of autoclaved aerated concrete strip board installation equipment, in particular to autoclaved aerated concrete strip board lifting equipment. Background Art

[0002] Autoclaved aerated concrete is a porous concrete product made from fly ash, lime, cement, gypsum, slag and other main raw materials, with appropriate amount of gas generating agent, regulator, bubble stabilizer, and through a process of batching, mixing, pouring, static stopping, cutting and high-pressure steam curing. Autoclaved aerated concrete board has the characteristics of light weight and excellent thermal insulation performance, so it is often used as wall material.

[0003] When installing autoclaved aerated concrete slats, it is necessary to manually erect the autoclaved aerated concrete slats and move them to the required installation location. However, this is not only difficult to adjust the installation location, but also consumes a lot of manpower. There is also a risk of the slats collapsing, causing damage, or even injury. Therefore, there is a need for a lifting device that can reduce the labor intensity during the installation of autoclaved aerated concrete slats and improve the safety of the installation process. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide an autoclaved aerated concrete slab lifting device to solve the problem that the autoclaved aerated concrete slab is time-consuming and labor-intensive and has high safety risks during installation.

[0005] The technical solution adopted by the present utility model is: a kind of autoclaved aerated concrete slat lifting equipment, comprising a support frame, a first driving mechanism is installed on the support frame, a fixed pulley is installed on the side of the support frame close to the wall, a rope is provided between the first driving mechanism and the fixed pulley, and the end of the rope away from the first driving mechanism passes around the fixed pulley and is connected to a lifting assembly, and the lifting assembly is connected to the autoclaved aerated concrete slat.

[0006] The above structure has the following beneficial effects:

[0007] The first driving mechanism drives the rope to move, and then drives the lifting assembly connected to the end of the rope to perform lifting movement, and then the autoclaved aerated concrete slats are lifted by the lifting assembly to facilitate their installation. In this way, not only can the labor intensity of workers during the installation of the autoclaved aerated concrete slats be reduced, but also the safety risks during the installation of the autoclaved aerated concrete slats can be reduced, thereby ensuring the safety of workers during the construction process.

[0008] Preferably, the support frame is further connected to a jacking assembly, which includes a fixing rod fixedly connected to the support frame and a jacking rod connected to the top of the fixing rod, and the jacking rod is abutted against the floor slab at the top of the floor.

[0009] The jacking assembly is connected to the floor slab at the top of the floor through the jacking rod, which can prevent the support frame from flipping or tipping over when the autoclaved aerated concrete slab is lifted, ensuring the safety of the lifting equipment during use.

[0010] Preferably, the supporting rod and the fixing rod are connected via threads.

[0011] The jacking rod is connected to the fixed rod by a thread, so that the extension length of the jacking rod can be adjusted to cope with the different heights of the floor slabs at the top of the floor. The jacking rod can be rotated according to the actual height of the floor slab to ensure that the jacking rod can be stably supported on the floor slab at the top of the floor.

[0012] Preferably, an adjusting sleeve is further provided between the supporting rod and the fixed rod, the lower end of the adjusting sleeve is connected to the fixed rod by a thread, the upper end of the adjusting sleeve is connected to the supporting rod by a thread, and the threads at the upper and lower ends of the adjusting sleeve have opposite rotation directions.

[0013] The two ends of the adjusting sleeve are respectively connected to the supporting rod and the fixed rod by threads, and the threads at both ends of the adjusting sleeve are rotated in opposite directions, so that when the adjusting sleeve is rotated, the supporting rod and the fixed rod can move in relative or opposite directions, thereby adjusting the extension length of the supporting rod. Such a setting can avoid friction between the end of the supporting rod and the floor slab at the top of the floor during the adjustment process, thereby reducing the wear of the supporting rod and increasing the service life of the lifting equipment.

[0014] Preferably, the lifting assembly includes a hanger bracket, a plurality of bolt holes are provided on the hanger bracket, a threaded hole is provided on the top of the autoclaved aerated concrete strip, the threaded hole matches the position of the bolt hole, and the autoclaved aerated concrete strip is connected to the bolt hole by connecting bolts.

[0015] When hoisting the autoclaved aerated concrete slats, two threaded holes are drilled on the top of the slats, and the hoist bracket is connected to the autoclaved aerated concrete slats through connecting bolts. This can achieve a stable connection effect and can stably hoist the autoclaved aerated concrete slats. It is suitable for situations where there is not much space at the top and other clamps cannot be used.

[0016] Preferably, the hoisting assembly includes a sling bracket and a clamping member mounted on the sling bracket. A chute is provided on the sling bracket. A slider slidably connected to the chute is provided at the top of the clamping member. The lower end of the clamping member is a "冂"-shaped clamping frame. One side wall of the clamping frame is a fixed side wall, and the other side wall of the clamping frame is a rotating side wall. A bolt group is connected between the fixed side wall and the rotating side wall of the clamping frame.

[0017] Through the cooperation between the chute provided on the sling and the slider on the clamping member, the clamping member can move along the chute, so as to clamp autoclaved aerated concrete slabs with different widths, improving the applicable range of the hoisting assembly. The "冂"-shaped clamping frame can facilitate the accommodation of autoclaved aerated concrete slabs. The fixed side wall and the rotating side wall of the clamping frame can be clamped by the bolt group, so that the two side walls of the clamping frame clamp the autoclaved aerated concrete slab therein, facilitating the lifting work of the autoclaved aerated concrete slab. In this way, the clamping of the autoclaved aerated concrete slab is convenient and fast, improving the clamping efficiency and reducing the damage to the autoclaved aerated concrete slab.

[0018] Preferably, a clamping plate is also rotatably connected to one side of the clamping frame. The clamping plate faces the other side of the clamping frame, and a number of fixed teeth are provided on the clamping plate.

[0019] The clamping plate rotatably connected to the clamping frame can be parallel to the fixed side wall during the clamping process, providing a more stable clamping state. At the same time, the setting of the fixed teeth can increase the friction between the clamping plate and the autoclaved aerated concrete slab, ensuring that the autoclaved aerated concrete slab can be clamped more stably.

[0020] Preferably, an extension bracket is further provided on the side of the support frame away from the wall surface, and the first driving mechanism is mounted on the extension bracket.

[0021] The setting of the extension bracket can make the support frame more stable. At the same time, by mounting the first driving mechanism on the extension bracket, the weight on the side of the support frame away from the hoisting assembly is increased, so that the support frame during the hoisting process is more stable and will not easily tip over.

[0022] Preferably, a second adjusting mechanism is further provided between the fixed pulley and the support frame. The second adjusting mechanism includes a rotating frame rotatably connected to the support frame. An adjusting pulley is mounted on the rotating frame, and the rope passes around the adjusting pulley after passing through the fixed pulley.

[0023] By adjusting the position of the rotating frame, the adjusting pulley can be driven to move toward the wall, so that temporary adjustment can be made when it is inconvenient to push the support frame to move, so that the lifting component can be closer to the wall, thereby facilitating the installation of the autoclaved aerated concrete slab.

[0024] Preferably, the support frame is further connected to a limiting frame, on which a limiting boss is provided. The rotating frame is further rotatably connected to a limiting rod, on which a plurality of limiting grooves for being embedded in the limiting boss are provided.

[0025] The limiting rod is embedded in the limiting boss, which can position the angle of the rotating frame to prevent the rotating frame from rotating when the autoclaved aerated concrete slab is lifted, thereby ensuring the safety and stability of the lifting work.

DETAILED DESCRIPTION

[0035] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0036] Example 1

[0037] According to the instruction manual Figure 1-4 As shown, the utility model provides an autoclaved aerated concrete slat lifting device, including a support frame 10, a first driving mechanism 13 is installed on the support frame 10, and a fixed pulley 11 is installed on the side of the support frame 10 close to the wall. In this embodiment, the support frame 10 is assembled with round tubes, and a universal wheel with a locking function is also installed at the bottom of the support frame 10, which can drive the support frame 10 to move, wherein the first driving mechanism 13 adopts a winch, and a rope 12 is wound around the winch, and the other telescopic end passes around the fixed pulley 11 and is connected to a lifting assembly 20, which is used to be connected to the autoclaved aerated concrete slat.

[0038] A jacking assembly 30 is also detachably installed on the top of the support frame 10, wherein the jacking assembly 30 includes a fixing rod 32 fixedly connected to the support frame 10 and a jacking rod 31 connected to the fixing rod 32. The top of the jacking rod 31 is a rectangular rubber part, which is abutted against the floor slab at the top of the floor through the jacking rod 31 to reduce the risk of the support frame 10 collapsing when the autoclaved aerated concrete slab is lifted. In this embodiment, an adjusting sleeve 33 is further installed between the supporting rod 31 and the fixed rod 32, wherein the bottom end of the adjusting sleeve 33 is connected to the fixed rod 32 by a thread, and the supporting rod 31 is connected to the upper end of the adjusting sleeve 33 by a thread, and the upper and lower ends of the adjusting sleeve 33 have opposite rotation directions, so that when the adjusting sleeve 33 is rotated, the supporting rod 31 and the fixed rod 32 move toward the adjusting sleeve 33 at the same time or move away from the adjusting sleeve 33 at the same time, which can facilitate the extension or retraction of the supporting rod 31. In this embodiment, four supporting assemblies 30 are installed, and are respectively located at the four corners of the support frame 10.

[0039] In this embodiment, a ladder 18 for workers to climb up and down is also provided on the support frame 10, and an operating platform is provided on the top of the support frame. A hole 17 for workers to pass through is opened on the operating platform 16. At the same time, in order to protect the safety of the operating workers during work, a guardrail and a vertical dense mesh with a height of at least 1.2 meters are provided on the outer periphery of the operating platform to reduce the risk of workers falling. On the outside of the support frame, several cross braces and diagonal braces are also installed to improve the stability of the support frame. However, in the attached drawings of the specification, the guardrail, dense mesh, cross braces and diagonal braces are hidden to facilitate a clearer display of the internal structure of the support frame.

[0040] In this embodiment, the hoisting assembly 20 includes a sling support 21 and a clamping member 22 installed on the sling support 21. At both ends of the sling support 21, sliding grooves 211 are respectively opened, and a slider is installed on the clamping member 22. The clamping member 22 is slidably connected in the sliding grooves 211 through the slider; in this embodiment, the lower end of the clamping member 22 is a "冂"-shaped clamping frame. One side of the clamping frame away from the wall is a fixed side wall 221, and one side of the clamping frame close to the wall is a rotating side wall 222. The rotating side wall 222 is rotatably connected to the clamping member 22, and clamping blocks are respectively rotatably connected to the fixed side wall 221 and the rotating side wall 222. Through holes are opened on the clamping blocks, and the two clamping blocks are connected by a bolt group 223, so that the rotating side wall 222 and the fixed partition clamp the autoclaved aerated concrete slab therein.

[0041] In this embodiment, a clamping plate 23 is also rotatably connected to the rotating side wall 222, and a plurality of fixed teeth 231 are uniformly arranged on the clamping plate 23. Through the arrangement of the clamping plate 23, the side surface of the clamping plate 23 can abut against the side surface of the autoclaved aerated concrete slab, increasing the clamping area and thus increasing the clamping force. At the same time, the arrangement of the fixed teeth 231 can further improve the friction during clamping, making the clamping process more stable.

[0042] The working principle is that when the autoclaved aerated concrete slab needs to be installed, the support frame 10 is pushed to the installation position. After the jacking rod 31 is raised and abuts against the floor slab at the top of the floor, the rope 12 is then wound around the fixed pulley 11 and connected to the sling support 21. The position of the clamping member 22 is adjusted, and the clamping member 22 is clamped on the autoclaved aerated concrete slab, and the clamping member 22 is locked by the bolt group 223. Then, by starting the first driving mechanism 13, the autoclaved aerated concrete slab can be lifted to facilitate the installation work.

[0043] Embodiment 2 [[ID=​​As shown, the difference between this embodiment and embodiment 1 is that an extension bracket 14 is further connected to the side of the support frame 10 away from the wall, wherein the first drive mechanism 13 is installed on the extension bracket 14. Through the provision of the extension bracket 14, on the one hand, the contact area with the ground is increased, and on the other hand, the weight of the side of the support frame 10 away from the wall is increased, so that the center of gravity of the support frame 10 is further toward the direction away from the wall, thereby making the lifting equipment more stable when performing the lifting work of the autoclaved aerated concrete slab, reducing the chance of the lifting equipment tipping over.

[0045] Example 3

[0046] According to the instruction manual Figure 6 As shown, the difference between this embodiment and embodiment 1 is that the lifting assembly includes a lifting bracket, the lifting bracket is provided with a plurality of bolt holes, the top of the autoclaved aerated concrete strip is provided with threaded holes, the positions of the threaded holes and the bolt holes are matched, and the autoclaved aerated concrete strip is connected to the bolt holes by connecting bolts.

[0047] When hoisting the autoclaved aerated concrete slats, two threaded holes are drilled on the top of the slats, and the hoist bracket is connected to the autoclaved aerated concrete slats through connecting bolts. This can achieve a stable connection effect and can stably hoist the autoclaved aerated concrete slats. It is suitable for situations where there is not much space at the top and other clamps cannot be used.

[0048] Example 4

[0049] According to the instruction manual Figure 7-8 As shown, the difference between this embodiment and embodiment 1 is that a second adjusting mechanism 40 is further installed between the fixed pulley 11 and the support frame 10, wherein the second adjusting mechanism 40 includes a rotating frame 41, the bottom end of the rotating frame 41 is rotatably connected to the support frame 10, and the rotating frame 41 is located on the side of the fixed pulley 11 close to the wall, and an adjusting pulley 42 is installed at the upper end of the rotating frame 41. The rope 12 passes through the fixed pulley 11, then bypasses the adjusting pulley 42 and is connected to the lifting assembly 20.

[0050] In this embodiment, a limiting frame 43 is also fixedly installed on the support frame 10, and a limiting boss 431 is provided on the limiting frame 43, and a limiting rod 44 is rotatably connected to the rotating frame 41. The limiting rod 44 is provided with a plurality of limiting grooves 441, and the limiting grooves 441 can be embedded in the limiting boss 431, thereby limiting the rotation angle of the rotating frame 41.

[0051] The working principle of this embodiment is that when the support frame 10 moves to the specified position and locks the roller, if the lifting distance is a certain distance from the installation position of the autoclaved aerated concrete slat, the rotating frame 41 can be rotated to adjust the position of the adjusting pulley 42 to adjust the lifting position. When the position adjustment is completed, the limit rod 44 is rotated to make the limit groove 441 with a suitable distance be embedded in the limit boss 431, and the angle of the rotating frame 41 is fixed to facilitate the lifting of the autoclaved aerated concrete slat.
