Description

Technical Field

[0001] The invention relates to the technical field of pipeline hoisting auxiliary devices, in particular to a pipeline vertical hoisting clamping device for construction engineering. Background Art

[0002] When bored piles are used in the project, casing is required for drilling rigs with drill rods or underwater concrete pouring, and the casing needs to be lifted and installed by vertical lifting methods. Traditional vertical lifting methods include single-point lifting and two-point lifting. The lifting point of single-point lifting is set in the middle of the pipeline, and the lifting point of two-point lifting is symmetrically set at the appropriate position of the pipeline based on experience. When the casing is lifted vertically, the lifting point is generally set by steel cable bundling or by clamps. However, steel cable bundling often cannot be tied tightly due to its considerable toughness, and thus requires continuous adjustment. There are certain safety risks during the lifting process, and the lifting points set by clamps need to be fastened with more bolts, which is cumbersome to operate and is not conducive to improving work efficiency. Summary of the invention

[0003] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a vertical lifting clamping device for pipes for construction engineering, and the technical solution to the problem is that it includes a pipe body, characterized in that a lower clamping sleeve is coaxially sleeved on the lower edge of the pipe body, an upper clamping sleeve is coaxially arranged on the upper edge of the pipe body, a support frame is coaxially fixedly connected to the upper end of the upper clamping sleeve, a hook assembly is coaxially arranged on the upper end of the support frame, the support frame is fixedly connected with two mounting rods arranged symmetrically about its axis, the opposite ends of the two mounting rods are fixedly connected with a transverse axis, the opposite ends of the two mounting rods are rotatably connected with a driving shaft arranged parallel to the transverse axis, the driving shaft is integrally arranged with two threaded portions with opposite thread rotation directions, each of the threaded portions is respectively threadedly connected with an adjusting rod slidably connected to the transverse axis, the lower ends of each adjusting rod are respectively fixedly connected with a clamping plate, each of the clamping plates is respectively integrally arranged with a downslope, and limiting grooves are respectively provided at the left and right ends of the lower clamping sleeve, and an upslope is integrally arranged in each limiting groove, and the downslope is abutted against the upslope in a one-to-one correspondence.

[0004] Preferably, the hook assembly comprises a connecting sleeve coaxially arranged with the supporting frame, the connecting sleeve is coaxially rotatably connected with a vertical rod, and the upper end of the vertical rod is coaxially fixedly connected with a hanging ring.

[0007] Preferably, the adjusting rod is integrally provided with a screw sleeve threadably matched with the threaded portion, and the adjusting rod is integrally provided with a sliding sleeve slidably matched with the transverse axis. The beneficial effects of the present invention are: When the present application is in use, the upper ferrule and the lower ferrule are respectively fixed to the upper edge and the lower edge of the pipe body, so that the pipe body can be tightly clamped for vertical lifting. In the present application, the two threaded portions with opposite thread directions on the driving shaft can drive the two adjusting rods to approach or move away synchronously, so that the two clamping plates can approach and move away synchronously, so as to facilitate the rapid connection and tightening of the upper ferrule and the lower ferrule.

[0013] The following is combined with Figure 1-4 The specific implementation modes of the present invention are further described in detail.

[0014] Embodiment 1, the technical solution is that, when the present application is in use, by fixing the upper ferrule 3 and the lower ferrule 2 respectively on the upper edge and the lower edge of the pipe body 1, the pipe body 1 can be tightly clamped for vertical lifting, and the two sections of threaded portions 9 with opposite thread rotation directions on the driving shaft 8 in the present application can drive the two adjusting rods 10 to approach or move away synchronously, so that the two clamping plates 11 can be approached and moved away synchronously, so as to facilitate the rapid connection and tightening of the upper ferrule 3 and the lower ferrule 2, the operation is simple, and it is beneficial to improve the work efficiency. Furthermore, in order to facilitate the connection and tightening of the upper ferrule 3 and the lower ferrule 2, a downward bevel 12 is provided on the clamping plate 11, and an upward bevel 14 corresponding to the downward bevel 12 is arranged in the limiting groove 13, so as to facilitate the docking of the clamping plate 11 and the lower ferrule 2, so as to quickly complete the tightening operation. The present application has a simple structure, is easy to use, and has strong practicality.

[0015] Embodiment 2, based on embodiment 1, specifically, when the present application is used, the upper ferrule 3 is as shown in the accompanying drawings of the specification. Figure 1 As shown, it is placed on the upper edge of the pipe body 1, and the lower ferrule 2 is placed on the lower edge of the pipe body 1 and corresponds to the upper ferrule 3. Then, the driving shaft 8 at the mounting rod 6 is rotated clockwise. A handwheel 19 is provided to facilitate the rotation of the driving shaft 8. When the driving shaft 8 is rotated clockwise, the two threaded portions 9 thereon will rotate synchronously therewith. Because the thread rotation directions of the two sections of the threaded portions 9 are opposite, the threaded portions 9 will act on the adjusting rod 10 through the screw sleeve 20 when the driving shaft 8 rotates clockwise, and the screw rod is restricted by the sliding connection between the sleeve 21 and the horizontal axis 7. Therefore, the clockwise rotation of the two threaded portions 9 will drive the two adjusting rods 10 to move relatively close to each other, and then the two clamping plates 11 will also move relatively close to each other synchronously. The relative movement of the two clamping plates 11 can make each downclimb 12 enter the limiting groove 13 on its corresponding side, and make the downclimb 12 dock with the upclimb 14 in the limiting groove 13 to complete the connection, thereby quickly completing the fastening connection between the upper ferrule 3 and the lower ferrule 2. Correspondingly, when the upper ferrule 3 and the lower ferrule 2 need to be separated, the driving shaft 8 only needs to be rotated counterclockwise, and the threaded portion 9 on the driving shaft will drive the two adjusting rods 10 to move away from each other, thereby causing the clamping plate 11 to disengage from the limiting groove 13, and the separation operation can be completed quickly.

[0016] Embodiment 3, on the basis of embodiment 2, the docking of the upper ferrule 3 and the lower ferrule 2 in this application is actually the docking of the upper slope 14 and the lower slope 12. The two are docked by the bevel surface, which not only increases the docking area, but also the bevel surface docking does not need to consider the problems of upper and lower misalignment and interference too much, thereby avoiding excessive adjustments and further improving work efficiency. In addition, the hook ring 17 of the hook assembly 5 provided on the support frame 4 can be connected to the hook of the external lifting equipment for vertical lifting. The vertical rod 16 of the hook assembly 5 is rotatably connected to the connecting sleeve 15 and can be rotated to facilitate the adjustment of the hook ring 17 to connect with the hook. The hollow groove 18 on the upper ferrule 3 and the lower ferrule 2 is convenient for reducing the overall weight of this application, making the whole lighter.
