Abstract
Description
Technical Field
[0001] This utility model relates to the field of concrete pipe installation technology, and in particular to an auxiliary device for hoisting concrete pipes. Background Technology
[0002] Currently, concrete pipe hoisting refers to the process in building construction where precast concrete pipes are lifted from the ground or transport vehicles using lifting equipment and precisely installed in their designed positions. This process is widely used in municipal engineering, drainage systems, water conservancy projects, and other fields for laying underground pipeline networks. Due to the relatively large weight of concrete pipes, the hoisting process is time-consuming and relatively inefficient.
[0003] A lifting tool exists in the related technology, including a connecting frame with hooks at both ends. The hooks are used to hook onto both ends of a concrete pipe. The connecting frame is lifted by a lifting device, and then the concrete pipe is lifted by the hooks, which reduces the time for binding the concrete pipe and improves the efficiency of lifting.
[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:
[0005] Because concrete is prone to shaking and rotation during hoisting, the hook is likely to slide relative to the inner wall of the concrete pipe, resulting in a relatively high risk of it falling off.
[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content
[0007] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.
[0008] This disclosure provides an auxiliary device for hoisting concrete pipes to reduce the risk of relative sliding between the first and second forks and the inner wall of the concrete pipe, thereby reducing the risk of the concrete pipe falling off during hoisting.
[0009] In some embodiments, the auxiliary device for hoisting concrete pipes includes: two auxiliary components, respectively disposed at both ends of the concrete pipe; each auxiliary component includes a sliding frame, a first fork arm, an adjusting block, a second fork arm, and a lead screw; the sliding frame is provided with a first sliding hole and a second sliding hole; one end of the first fork arm is slidably connected to the first sliding hole; the adjusting block is rotatably connected to the middle of the first fork arm; one end of the second fork arm is slidably connected to the second sliding hole, and the middle is rotatably connected to the adjusting block; one end of the lead screw is rotatably connected to the sliding frame and threadedly connected to the adjusting block; wherein both ends of the first fork arm and both ends of the second fork arm can abut against the inner wall of the concrete pipe.
[0010] Optionally, a first raised frame is provided in the middle of the first fork arm, and a second raised frame is provided in the middle of the second fork arm. One end of the adjusting block is rotatably connected to the first raised frame, and the other end of the adjusting block is rotatably connected to the second raised frame.
[0011] Optionally, the first fork arm is rotatably provided with a first sliding arm at the end facing the sliding frame, and the end of the first sliding arm facing away from the first fork arm extends into the first sliding hole and is slidably connected thereto; the second fork arm is rotatably provided with a second sliding arm at the end facing the sliding frame, and the end of the second sliding arm facing away from the second fork arm extends into the second sliding hole and is slidably connected thereto.
[0012] Optionally, the first sliding arm includes: a first connecting plate and a second connecting plate. One end of the first connecting plate is rotatably connected to the first fork arm; the second connecting plate is perpendicularly disposed to and fixedly connected to the first connecting plate, and one end extends into the first sliding hole and is slidably connected thereto; wherein, the direction in which the first connecting plate extends is parallel to the direction in which the second connecting plate slides in the first sliding hole.
[0013] Optionally, both ends of the sliding frame are provided with lifting holes.
[0014] Optionally, the sliding frame is provided with lifting rings at both ends, and the lifting rings are inserted into the lifting holes.
[0015] Optionally, a strapping frame is provided in the middle of the sliding frame, and the strapping frame is provided with strapping holes.
[0016] Optionally, a rotating handle is fixedly provided at the end of the lead screw facing the sliding frame.
[0017] The auxiliary device for hoisting concrete pipes provided in this disclosure can achieve the following technical effects:
[0018] The first and second forks are inserted into one end of the concrete pipe, with the sliding frame abutting against the edge of the pipe. Rotating the screw on the sliding frame causes the adjusting block to move relative to the screw, shortening the distance between the adjusting block and the sliding frame. The first fork slides relative to the first sliding hole, and the second fork slides relative to the second sliding hole, until both ends of the first and second forks abut against the inner wall of the concrete pipe, completing the installation of one auxiliary component. Similarly, the other auxiliary component is installed at the other end of the concrete pipe. The two sliding frames are then lifted using lifting equipment, thereby lifting the concrete pipe. The multiple abutment points between the two first and second forks and the inner wall of the concrete pipe reduce the risk of slippage between the first and second forks and the inner wall, thus reducing the risk of the concrete pipe detaching during lifting.
[0019] The above general description and the description below are exemplary and illustrative only, and are not intended to limit this application. Attached Figure Description

[0030] Unless otherwise stated, the term "multiple" means two or more.
[0031] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.
[0032] Combination Figure 1-2 As shown, this embodiment of the present disclosure provides an auxiliary device for hoisting concrete pipes, comprising: two auxiliary components 010, respectively disposed at both ends of the concrete pipe; each auxiliary component 010 includes a sliding frame 100, a first fork arm 200, an adjusting block 300, a second fork arm 400, and a lead screw 500; the sliding frame 100 is provided with a first sliding hole 110 and a second sliding hole 120; one end of the first fork arm 200 is slidably connected to the first sliding hole 110; the adjusting block 300 is rotatably connected to the middle of the first fork arm 200; one end of the second fork arm 400 is slidably connected to the second sliding hole 120, and the middle is rotatably connected to the adjusting block 300; one end of the lead screw 500 is rotatably connected to the sliding frame 100 and threadedly connected to the adjusting block 300; wherein both ends of the first fork arm 200 and both ends of the second fork arm 400 can abut against the inner wall of the concrete pipe.
[0033] Using the auxiliary device for hoisting concrete pipes provided in this embodiment, the first fork arm 200 and the second fork arm 400 are inserted through one end of the concrete pipe, and the sliding frame 100 abuts against the edge of the concrete pipe. Rotating the lead screw 500 on the sliding frame 100 causes the adjusting block 300 to move relative to the lead screw 500, thus shortening the distance between the adjusting block 300 and the sliding frame 100. The first fork arm 200 slides relative to the first sliding hole 110, and the second fork arm 400 slides relative to the second sliding hole 120, until both ends of the first fork arm 200 and the second fork arm 400 abut against the inner wall of the concrete pipe, thereby completing the installation of one auxiliary component 010. Similarly, the other auxiliary component 010 is installed to the other end of the concrete pipe. Then, the two sliding frames 100 are lifted using lifting equipment, thereby lifting the concrete pipe. Both first fork arms 200 and two second fork arms 400 abut against the inner wall of the concrete pipe. The relatively large number of abutment and support points reduces the risk of relative sliding between the first fork arms 200 and the second fork arms 400 and the inner wall of the concrete pipe, thereby reducing the risk of the concrete pipe falling off during hoisting.
[0034] Understandably, as the lead screw 500 rotates, the distance between the adjusting block 300 and the sliding frame 100 increases, thus decreasing the distance between the ends of the first fork arm 200 and the second fork arm 400 and the lead screw 500. Conversely, the decrease in the distance between the adjusting block 300 and the sliding frame 100 leads to a greater distance between the ends of the first fork arm 200 and the second fork arm 400 and the lead screw 500. This allows for adaptation to concrete pipes of different diameters, providing a wide range of compatibility and simplifying operation.
[0035] Optionally, a fixed seat 130 is provided in the middle of the sliding frame 100, and the fixed seat 130 is rotatably connected to the lead screw 500. In this way, the fixed seat 130 is rotatably connected to the lead screw 500, and the stability is relatively high.
[0036] Specifically, the first sliding hole 110 and the second sliding hole 120 are provided on both sides of the fixed base 130. In this way, the first sliding hole 110 and the second sliding hole 120 are not connected to each other, and the risk of interference between the first fork arm 200 and the second fork arm 400 is relatively low.
[0037] Combination Figure 3As shown, optionally, a first raised frame 210 is provided in the middle of the first fork arm 200, and a second raised frame 410 is provided in the middle of the second fork arm 400. One end of the adjusting block 300 is rotatably connected to the first raised frame 210, and the other end of the adjusting block 300 is rotatably connected to the second raised frame 410. In this way, the interval between the first raised frame 210 and the second raised frame 410 is relatively large, and the risk of mutual interference is relatively low. Furthermore, the risk of interference between the first raised frame 210 and the second raised frame 410 and the lead screw 500 is also relatively low, increasing the angle at which the first fork arm 200 and the second fork arm 400 can rotate relative to the adjusting block 300.
[0038] Optionally, the first raised frame 210 is provided with a first clearance groove 211 on the side facing the second fork arm 400. This results in a relatively large gap between the first raised frame 210 and the second raised frame 410, reducing the risk of mutual interference. Increasing the angle at which the first fork arm 200 and the second fork arm 400 can rotate relative to the adjusting block 300 also increases the angle of rotation.
[0039] Optionally, the second raised frame 410 is provided with a second clearance groove 411 on the side facing the first fork arm 200. This results in a relatively large gap between the first raised frame 210 and the second raised frame 410, reducing the risk of mutual interference. Increasing the angle at which the first fork arm 200 and the second fork arm 400 can rotate relative to the adjusting block 300 also increases the angle of rotation.
[0040] Optionally, the first fork arm 200 has a first sliding arm 220 rotatably mounted at one end facing the sliding frame 100, and the end of the first sliding arm 220 facing away from the first fork arm 200 extends into and is slidably connected to the first sliding hole 110; the second fork arm 400 has a second sliding arm 420 rotatably mounted at one end facing the sliding frame 100, and the end of the second sliding arm 420 facing away from the second fork arm 400 extends into and is slidably connected to the second sliding hole 120. In this way, the first sliding arm 220 can slide within the first sliding hole 110, and the first sliding arm 220 rotates relative to the first fork arm 200, restricting the adjusting block 300 from rotating with the lead screw 500; when the adjusting block 300 moves relative to the lead screw 500, the first fork arm 200 can also rotate relative to the adjusting block 300. The second sliding arm 420 can slide within the second sliding hole 120, and the second sliding arm 420 rotates relative to the second fork arm 400, restricting the adjusting block 300 from rotating with the lead screw 500; when the adjusting block 300 moves relative to the lead screw 500, the second fork arm 400 can also rotate relative to the adjusting block 300.
[0041] Combination Figure 4As shown, optionally, the first sliding arm 220 includes a first connecting plate 221 and a second connecting plate 222. One end of the first connecting plate 221 is rotatably connected to the first fork arm 200; the second connecting plate 222 is perpendicularly disposed to and fixedly connected to the first connecting plate 221, and one end extends into the first sliding hole 110 for sliding connection; wherein, the direction of extension of the first connecting plate 221 is parallel to the direction of sliding of the second connecting plate 222 in the first sliding hole 110. In this way, when the first fork arm 200 extends into the concrete pipe and abuts against the inner wall of the concrete pipe, there is always a gap between the first connecting plate 221 and the second connecting plate 222 and the inner wall of the concrete pipe, reducing the risk of interference between the first connecting plate 221 and the second connecting plate 222 and the inner wall of the concrete.
[0042] It is understandable that the second sliding arm 420 has the same or similar structure as the first sliding arm 220, and will not be described in detail here.
[0043] Optionally, the adjusting block 300 includes an adjusting seat 310 and a rotating shaft 320. The adjusting seat 310 has rotating shafts 320 fixedly mounted on both sides. The adjusting seat 310 is threadedly connected to the lead screw 500. The first fork arm 200 is rotatably connected to one of the rotating shafts 320, and the second fork arm 400 is rotatably connected to the other rotating shaft 320. This rotatable connection between the rotating shaft 320 and the first fork arm 200 and the second fork arm 400 provides relatively high stability.
[0044] Specifically, the first raised frame 210 is rotatably connected to one of the rotating shafts 320, and the second raised frame 410 is rotatably connected to the other rotating shaft 320. In this way, the stability of the connection is relatively high.
[0045] Optionally, both ends of the sliding frame 100 are provided with lifting holes 140. In this way, the lifting equipment can lift the sliding frame 100 through the lifting holes 140, and then lift the first fork arm 200, the second fork arm 400 and the concrete pipe, making the lifting more convenient.
[0046] Optionally, the lifting hole 140 includes a first hole portion 141 and a second hole portion 142. The first hole portion 141 and the second hole portion 142 are arranged vertically, and the first hole portion 141 is arranged parallel to the first sliding hole 110. In this way, the lifting equipment can be lifted to a relatively large number of positions through the first hole portion 141 and the second hole portion 142, making the lifting of concrete pipes more flexible.
[0047] Optionally, lifting rings 150 are movably provided at both ends of the sliding frame 100, and the lifting rings 150 pass through the lifting holes 140. In this way, the lifting equipment can lift the sliding frame 100 through the lifting rings 150, and then lift the first fork arm 200, the second fork arm 400 and the concrete pipe, making the lifting more convenient.
[0048] Combination Figure 5 As shown, optionally, a binding frame 160 is provided in the middle of the sliding frame 100, and the binding frame 160 is provided with binding holes 161. In this way, the two sliding frames 100 are bound and fixed together through the binding holes 161 on the binding frame 160, which reduces the risk of the two sliding frames 100 being far away from the edge of the concrete pipe and improves the stability of the hoisting.
[0049] Specifically, the strapping frame 160 and the adjusting seat 310 are fixedly connected.
[0050] Optionally, the two auxiliary components 010 are bound together by a binding rope 170. In this way, the two sliding frames 100 are bound together by the binding holes 161 on the binding frame 160 and the binding rope 170, which reduces the risk of the two sliding frames 100 being far away from the edge of the concrete pipe and improves the stability of the hoisting.
[0051] Specifically, the two adjustment seats 310 are tied and fixed together by a binding rope 170.
[0052] Optionally, a rotating handle 510 is fixedly provided at one end of the lead screw 500 facing the sliding frame 100. In this way, the relative position of the lead screw 500 and the adjusting block 300 can be adjusted by rotating the handle 510, making the adjustment more convenient.
