Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pipeline hoisting, in particular to a concrete pipeline hoisting device. Background Art
[0002] When urban municipal roads are being built, gravity pipelines for rainwater, sewage, etc. are usually planned and designed along both sides of the route. Such pipelines are generally made of concrete, with pipe sections ranging from 2 to 3 meters in length. On-site installation generally uses a crane hanging a wire rope for direct lifting, which not only cannot guarantee safety and installation quality, but also because the wall thickness of the pipe section is small, especially the connection between each two pipe sections is easily damaged during the lifting process.
[0003] Moreover, when traditional lifting devices are used to lift concrete pipes, due to the weight of the concrete pipes themselves and the inertia problems during the lifting process, as well as the structural design defects of the lifting devices themselves, the concrete pipes will shake and move during the lifting process. In severe cases, the concrete pipes may fall off, causing risks such as damage to the concrete pipes and casualties. Utility Model Content
[0004] The utility model aims to solve at least one technical problem in the background technology and provides a concrete pipe hoisting device.
[0005] In order to achieve the above-mentioned purpose, the utility model provides a concrete pipe hoisting device, comprising:
[0006] First beam;
[0007] a longitudinal beam, one end of which is vertically connected to one end of the first cross beam;
[0008] A second cross beam is arranged in parallel with the first cross beam in the same direction, and one end of the second cross beam is vertically connected to the other end of the longitudinal beam;
[0009] A counterweight structure, arranged at the other end of the first crossbeam;
[0010] a sling structure connected to the first beam and a side of the counterweight structure facing away from the second beam;
[0011] A buffer damping pad is provided on the side wall of the longitudinal beam close to the other end of the first cross beam and the side wall of the second cross beam facing the first cross beam;
[0012] The other end of the second cross beam is provided with a locking structure for locking the concrete pipe.
[0013] According to one aspect of the present invention, the length of the second cross beam is longer than the sum of the lengths of the first cross beam and the counterweight structure.
[0014] According to one aspect of the utility model, the side wall of the second cross beam facing the first cross beam is an inclined surface, and the side of the inclined surface close to the longitudinal beam is a lower side, and the side away from the longitudinal beam is a higher side.

[0022] According to one scheme of the utility model, a concrete pipe hoisting device comprises: a first crossbeam; a longitudinal beam, one end of which is vertically connected to one end of the first crossbeam; a second crossbeam, which is arranged in the same direction and parallel to the first crossbeam, and one end of which is vertically connected to the other end of the longitudinal beam; a counterweight structure, which is arranged at the other end of the first crossbeam; a sling structure, which is connected to the first crossbeam and the counterweight structure on the side away from the second crossbeam; a buffer damping pad is provided on the side wall of the longitudinal beam close to the other end of the first crossbeam and the side wall of the second crossbeam facing the first crossbeam; and a locking structure for locking the concrete pipe is provided at the other end of the second crossbeam. In this way, the structure of the position touched by the concrete pipe or easily touched by the concrete pipe in the concrete pipe hoisting device of the utility model can be effectively protected by the buffer damping pad, so as to prevent the concrete pipe from damaging the corresponding structure when it is in rigid contact with each position. In addition, the buffer damping pad can also increase the friction force on the concrete pipe, so as to ensure that the concrete pipe has greater friction resistance during the hoisting process, so that the concrete pipe is not easy to move and fall off from the second crossbeam. Furthermore, by setting the locking structure, the concrete pipe can be locked on the second beam to ensure that the concrete pipe will not fall off the second beam under any circumstances during the lifting and transportation process, ensuring that no damage or other safety accidents will occur.

[0029] The present invention will now be discussed with reference to exemplary embodiments. It should be understood that the embodiments discussed are only intended to enable those skilled in the art to better understand and implement the present invention, rather than to imply any limitation on the scope of the present invention.
[0030] As used herein, the term “including” and variations thereof are to be interpreted as open-ended terms meaning “including, but not limited to.” The term “based on” is to be interpreted as “based, at least in part, on.” The terms “one embodiment” and “an embodiment” are to be interpreted as “at least one embodiment.”
[0031] Figure 1 The structural layout diagram of the concrete pipe hoisting device according to one embodiment of the utility model is schematically shown. Figure 1 As shown, in this embodiment, the concrete pipe hoisting device includes:
[0032] First beam 1;
[0033] A longitudinal beam 2, one end of which is vertically connected to one end of the first cross beam 1;
[0034] The second cross beam 3 is arranged in parallel with the first cross beam 1 in the same direction, and one end of the second cross beam 3 is vertically connected to the other end of the longitudinal beam 2;
[0035] A counterweight structure 4 is arranged at the other end of the first beam 1;
[0036] a sling structure 5 connected to the first cross beam 1 and the counterweight structure 4 on a side facing away from the second cross beam 3;
[0037] A buffer damping pad 6 is provided on the side wall of the longitudinal beam 2 close to the other end of the first cross beam 1 and the side wall of the second cross beam 3 facing the first cross beam 1;
[0038] The other end of the second crossbeam 3 is provided with a locking structure 7 for locking the concrete pipe 10. With such a configuration, the structure of the position touched by the concrete pipe or easily touched by the concrete pipe in the concrete pipe lifting device of the utility model can be effectively protected by the buffer damping pad 6, preventing the concrete pipe from damaging the corresponding structure when it is in rigid contact with each position. In addition, the buffer damping pad 6 can also increase the friction force on the concrete pipe, ensuring that the concrete pipe has greater friction resistance during the lifting process, making it difficult for the concrete pipe to move and fall off from the second crossbeam 3. Furthermore, by setting the locking structure 7, the concrete pipe can be locked on the second crossbeam 3, ensuring that the concrete pipe will not fall off the second crossbeam 3 under any circumstances during the lifting and transportation process, ensuring that damage and other safety accidents will not occur.
[0039] Furthermore, if Figure 1 As shown, in this embodiment, the length of the second cross beam 3 is longer than the sum of the lengths of the first cross beam 1 and the counterweight structure 4. This arrangement can ensure that during the process of hoisting the concrete pipe, the center of gravity of the concrete pipe is stable, and there is no danger of moving toward the free end of the second cross beam 3 and falling off.
[0040] Further, preferably, the second cross beam 3 faces the side wall of the first cross beam 1 (ie Figure 1 The upper side wall of the middle side is an inclined surface, and the side of the inclined surface close to the longitudinal beam 2 is the lower side, and the side away from the longitudinal beam 2 is the higher side. That is, the width of the left free end of the second cross beam 3 is greater than the width of the part located at its rear side and the right end. With such an arrangement, after the concrete pipe is sleeved on the second cross beam 3, the end close to the longitudinal beam 2 will sink downward, and the end away from the longitudinal beam 2 will slightly tilt up, so that the concrete pipe can be stably and securely supported on the second cross beam 3 and squeezed toward one side of the longitudinal beam 2, ensuring that it will not move or fall off during the hoisting process.
[0041] According to one embodiment of the present invention, Figure 1 As shown, the locking structure 7 includes a mounting end 8 and a locking end 9;
[0042] The mounting end 8 is rotatably connected to the outer wall of the end of the second beam 3;
[0043] The locking end 9 is fixedly connected to the mounting end 8, and the locking end 9 can be turned around the end of the second beam 3 by rotating the mounting end 8. In this way, the locking end 9 can be turned to the upper side of the end of the second beam 3, thereby limiting the position of the concrete pipe sleeved on the second beam 3, ensuring that the concrete pipe can always be on the second beam 3 during the process of being hoisted and transported, and the two ends are always located between the locking end 9 and the longitudinal beam 2, ensuring that there will be no movement or falling off.
[0044] Further, according to another embodiment of the present utility model, the locking structure 7 includes: a mounting end and a locking end;
[0045] The mounting end is reciprocatably arranged in the central slide groove;
[0046] After the locking end extends out of the central chute, it can be connected to the concrete pipe and lock the concrete pipe. In this embodiment, the locking end can be made of a flexible material and a locking hook, and the concrete pipe is tightly wound by the flexible material, and then the corresponding matching structure is hooked by the locking hook, so that the concrete pipe is held in the opposite direction to the free end of the second cross beam 3, so that the concrete pipe is locked during the process of hoisting and transporting the concrete pipe, ensuring that it does not move or fall off, and ensuring hoisting safety.
[0047] Of course, the mounting end may also be fixedly arranged in the above-mentioned central slide groove, and of course, may also be fixedly arranged in other positions, as long as the concrete pipe can be locked and fixed.
[0048] According to the above scheme of the utility model, the first crossbeam and the second crossbeam in the utility model adopt H-shaped steel of 200*200*8*12mm, and 8mm thick steel plates are welded on both sides of the H-shaped steel for sealing. The first crossbeam is designed with a counterweight box (counterweight structure 4) and varying numbers of lifting ears (sling structures 5). The second crossbeam is designed with a rubber anti-collision pad (buffer damping pad 6) to avoid stress concentration on the contact surface between the pipeline and the H-shaped steel and cause damage to the pipeline. The anti-fall block is also designed with a rubber anti-collision pad to prevent the pipeline from sliding outward and causing extrusion damage to the concrete pipeline.
[0049] According to the above scheme of the utility model, the utility model can ensure that the concrete pipe will not cause large rigid collision and damage during hoisting, and at the same time can effectively ensure the supporting position of the concrete pipe, ensuring that it will not move significantly or even fall off during the hoisting and transportation process, thereby ensuring hoisting safety.
[0050] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the utility model.
