Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, and in particular to a lifting equipment for lifting prefabricated pipes used in building construction. Background Technology

[0002] After prefabricated pipelines are manufactured in the factory, specialized hoisting equipment is needed to transport them to transport vehicles or construction sites to ensure the safety and efficiency of the hoisting process. However, existing hoisting equipment has the following problems in suspending prefabricated pipelines: 1. Because the existing lifting equipment does not have components to provide rigid support for the inner sidewall of the precast pipe, it relies solely on simple clips to hook onto both ends of the pipe and then lift the pipe. During the process, the middle section of the pipe is not supported by force, causing the pipe to sway in the air after being lifted, which can easily lead to the pipe falling off and poses a safety hazard.

[0003] 2. The existing lifting equipment requires at least two people to install and remove the clamps on both sides of the pipe during the lifting and unloading process. If one side is not installed properly, the pipe will fall after being lifted, thus posing a safety problem. Utility Model Content

[0004] In order to solve the above problems, the purpose of this utility model is to provide a lifting tool for lifting prefabricated pipes used in building construction, which solves the problem of swaying when the existing lifting tool lifts the prefabricated pipes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A lifting device for lifting prefabricated pipes for building construction, which is suspended on the hook of a crane, includes a horizontal lifting column extending in the left and right direction, a vertical connecting column fixed to the lower left side of the horizontal lifting column, two sets of suspension components arranged at intervals in the left and right direction on the upper side of the horizontal lifting column for suspending the horizontal lifting column on the hook of the crane, and a limiting component provided on the vertical connecting column for limiting the back-and-forth swaying of the pipe suspended on the suspension column. The limiting component includes a horizontal suspension column fixedly connected at the left end to the lower part of the vertical connecting column; The right end of the suspension column is inclined upward relative to the transverse suspension column; Each suspension assembly includes a fixing plate fixed to the upper side of the horizontal suspension column, a mounting hole on the fixing plate, a detachable bow-shaped shackle on the mounting hole, and a suspension rope loop fitted inside the bow-shaped shackle. Each of the aforementioned lifting rope loops is fitted onto the hook at the end furthest from the bow-shaped shackle; The horizontal support column is equipped with a straightening component for making the horizontal support column horizontal.

[0006] More preferably, each of the bow-shaped shackles has a fastening screw threaded through both free ends, and each of the fastening screws is provided through a corresponding mounting hole.

[0007] More preferably, the straightening assembly includes a fixing hook fixed to the left side of the front side wall of the transverse hanging column, a constraint rope sleeved on the right side hanging rope loop, and a constraint ring sleeved on the end of the upper constraint rope away from the corresponding side hanging rope loop.

[0008] More preferably, the limiting assembly further includes movable grooves disposed on the front and rear sides of the suspension column along the length of the suspension column, a pair of rotating shafts respectively fixed on the front and rear sides of the left side of the movable grooves, two limiting members rotatably disposed on the corresponding rotating shafts in one-to-one correspondence, a pair of limiting tracks respectively disposed on the front and rear sides of the inner wall of the suspension column and respectively disposed along the length of the suspension column, a control member slidably disposed in the suspension column and respectively slidably disposed in the corresponding limiting tracks at the front and rear ends, a threaded sleeve fixedly disposed at the left end of the suspension column and disposed along the length of the suspension column, and a control rod movably disposed in the suspension column along the length of the suspension column and threadedly connected to the inner wall of the threaded sleeve; The control component is located on the left side of the limiting component, and the left end of the control rod extends through and out of the left side wall of the suspension column.

[0009] More preferably, a limiting block is fixedly provided on the left side of each of the two rotating shafts in the movable groove.

[0010] More preferably, a traction ring is fixed on the constraint ring.

[0011] More preferably, a traction hook is fixedly provided at the left end of the control lever.

[0012] This utility model has the following beneficial effects: 1. This utility model suspends a prefabricated pipe on a suspension column, and then uses a suspension assembly to lift the horizontal suspension column, thereby applying a rigid support force to the upper side of the inner wall of the prefabricated pipe. Furthermore, the right end of the suspension column is inclined upward relative to the horizontal suspension column, so that during the hoisting process, the prefabricated pipe naturally moves down under its own weight and abuts against the vertical connecting column, causing the prefabricated pipe to be supported by the vertical connecting column during the hoisting process, thereby stabilizing the prefabricated pipe and preventing the pipe from swaying during the hoisting process. 2. This utility model applies supporting force to the front and rear sides of the inner wall of the precast pipe suspended on the suspension column through the limiting component, so that during the process of suspending the precast pipe on the suspension column, the front and rear sides of the precast pipe are supported by the limiting components on both sides, thereby further preventing the precast pipe from swaying in the front and rear directions.

[0015] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. like Figure 1 , Figure 5 and Figure 6 As shown in the figure, a lifting device for lifting prefabricated pipes for building construction is provided in this embodiment. It is suspended on the hook 1 of a crane and includes a horizontal lifting column 2 extending in the left and right direction, a vertical connecting column 3 fixedly on the lower left side of the horizontal lifting column 2, two sets of suspension components 5 arranged at intervals in the left and right direction on the upper side of the horizontal lifting column 2 for suspending the horizontal lifting column 2 on the hook of the crane, and a limiting component 6 provided on the vertical connecting column 3 for limiting the back-and-forth swaying of the pipe suspended on the suspension column 68. The limiting component 6 includes a horizontal suspension column 68 fixedly connected at its left end to the lower part of the vertical connecting column 3; The right end of the suspension column 68 is inclined upward relative to the transverse suspension column 2; Each suspension assembly 5 includes a fixing plate 51 fixed to the upper side of the horizontal suspension column 2, a mounting hole 52 on the fixing plate 51, a bow-shaped shackle 53 detachably provided on the mounting hole 52, and a suspension rope loop 54 sleeved in the bow-shaped shackle 53. Each hoisting rope loop 54 is fitted onto the hook 1 at the end furthest from the bow-shaped shackle 53; The horizontal hanging column 2 is equipped with a straightening component 7 for making the horizontal hanging column 2 horizontally horizontal.

[0016] When using this product, the upper end of the suspension rope loop 54 inside the two side suspension components 5 is fitted onto the crane hook 1. Then, the crane is controlled to move downwards, causing the suspension column 68 to move downwards and into the precast pipe. As it continues to move downwards, the lower side of the transverse suspension column 2 abuts against and fits against the upper side of the precast pipe. Figure 5 As shown, the two suspension rope loops 54 are then taut using the straightening assembly 7, and the horizontal suspension column 2 is kept horizontal. The prefabricated pipe is then suspended on the suspension column 68 and slid downwards along the inclined direction of the suspension column 68 until the left end abuts against the vertical connecting column 3. Figure 6 As shown, this causes the suspension column 68 to apply a rigid supporting force to the upper side of the inner wall of the precast pipe, and is supported by the vertical connecting column 3, thereby preventing the precast pipe from shaking.

[0017] like Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown, each bow-shaped shackle 53 has a fastening screw 8 threaded through its two free ends, and each fastening screw 8 is set through the corresponding mounting hole 52.

[0018] When using this product, the bow-shaped shackle 53 is installed and fixed on the corresponding side fixing plate 51 by fastening screws 8.

[0019] like Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, the straightening assembly 7 includes a fixing collar 71 sleeved on the right-side suspension rope loop 54, a fixing hook 72 fixed on the left side of the front side wall of the transverse suspension column 2, a constraint ring 73 sleeved on the fixing hook 72, and a constraint rope 74 provided on the constraint ring 73 and used to connect the constraint ring 73 and the fixing collar 71.

[0020] When in use, this product drives the constraint ring 73 to hook onto the fixed hook 72, causing the constraint rope 74 to straighten and fix the longer right-side suspension rope loop 54. Then, the hook 1 is driven upwards, tauting both suspension rope loops 54 and keeping the horizontal suspension column 2 horizontal. The prefabricated pipe is then suspended on the suspension column 68 and slides downwards along the inclined direction of the suspension column 68 until it abuts against the vertical connecting column 3 at the left end. Figure 6 As shown.

[0021] like Figure 1 , Figure 3 and Figure 4As shown, the limiting assembly 6 also includes movable grooves 61 provided on the front and rear sides of the suspension column 68 along the length direction of the suspension column 68, a pair of rotating shafts 62 respectively fixed on the front and rear sides of the left side of the movable grooves 61, two limiting members 63 rotatably provided on the corresponding rotating shafts 62 in a one-to-one correspondence with each rotating shaft 62, a pair of limiting tracks 64 respectively provided on the front and rear sides of the inner wall of the suspension column 68 and respectively provided along the length direction of the suspension column 68, a control member 65 slidably provided in the suspension column 68 and respectively slidably provided in the corresponding limiting tracks 64 at both ends, a threaded sleeve 66 fixed at the left end of the suspension column 68 and provided along the length direction of the suspension column 68, and a control rod 67 movably provided in the suspension column 68 along the length direction of the suspension column 68 and threadedly connected to the inner wall of the threaded sleeve 66. The control component 65 is located on the left side of the limiting component 63, and the left end of the control rod 67 extends through and out of the left side wall of the suspension column 68.

[0022] When using this product, insert the end of the control rod 67 away from the traction hook 11 into the suspension column 68 through the threaded sleeve 66, rotate the control rod 67 to move it along the thread direction of the threaded sleeve 66, so that the end of the control rod 67 abuts against the control component 65, and drives the control component 65 to move along the length direction of the limiting track 64, so that it pushes the limiting components 63 on both sides, and drives the limiting components 63 to rotate along the corresponding side rotation shaft 62, and drives the limiting components 63 on both sides to extend out from the front and rear sides of the movable groove 61 until the ends of the limiting components 63 abut against the front and rear sides of the inner wall of the precast pipe, thereby achieving the effect of further stabilizing the suspension of the precast pipe.

[0023] like Figure 1 and Figure 4 As shown, a limiting block 9 is fixedly installed on the left side of each of the two rotating shafts 62 in the movable groove 61.

[0024] When this product is in use, the left end of the two side limiters 63 is restricted from rotating and extending out of the movable groove 51 by the limiting block 9. like Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, a traction ring 10 is fixed on the constraint ring 73.

[0025] When using this product, pulling the traction ring 10 causes the constraint rope 74 to tighten the longer suspension rope loop 54 on the right side, making it easier for the operator to find the position to apply force.

[0026] like Figure 1 , Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, a traction hook 11 is fixed to the left end of the control lever 67.

[0027] When using this product, the operator can easily pull the traction ring 10 by means of the traction hook 11.

[0028] The working principle of this device is as follows: Step 1: Place the upper end of the suspension rope loop 54 inside the suspension components 5 on the crane hook 1, then control the crane to move downwards, causing the suspension column 68 to move downwards and into the precast pipe. Continue to move downwards until the lower side of the transverse suspension column 2 abuts against and fits against the upper side of the precast pipe. Figure 5 As shown.

[0029] Step 2: Then, hold the control lever 67 and hook the traction hook 11 into the traction ring 10. Pull down the traction ring 10, causing the constraint ring 73 to hook onto the fixed hook 72, thus straightening the longer right-side suspension rope loop 54 of the constraint rope 74 and fixing it. Then, drive the hook 1 to move upward, so that the suspension rope loops 54 on both sides are taut and the horizontal suspension column 2 remains horizontal, suspending the prefabricated pipe on the suspension column 68, and sliding it downward along the inclined direction of the suspension column 68 until the left end abuts against the vertical connecting column 3. Figure 6 As shown.

[0030] Step 3: Then, insert the end of the control rod 67 away from the traction hook 11 into the suspension column 68 through the threaded sleeve 66, rotate the control rod 67 to move it along the thread direction of the threaded sleeve 66, so that the end of the control rod 67 abuts against the control member 65, and drives the control member 65 to move along the length direction of the limiting track 64, so that it pushes the limiting members 63 on both sides, and drives the limiting members 63 to rotate along the corresponding side rotation shaft 62, and drives the limiting members 63 on both sides to extend out from the front and rear sides of the movable groove 61 until the ends of the limiting members 63 abut against the front and rear sides of the inner wall of the precast pipe, thereby achieving the effect of further stabilizing the suspension of the precast pipe.

[0031] Step 4: After suspending the precast pipe to the corresponding position, lower the hook 1 so that the lower left end of the precast pipe touches the ground. Then, rotate the control lever 67 to remove it, and hook the traction hook 11 into the traction ring 10. Pull the traction ring 10 outwards, causing it to disengage from the fixed hook 72. This causes the right end of the horizontal suspension column 2 to move downwards, and the suspension column 68 to rotate to a horizontal position, resulting in the precast pipe being placed horizontally on the ground. Figure 7 As shown.

Any equivalent structural transformations made based on the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
