Description

Technical Field

[0001] The utility model relates to a hoist for construction, and particularly to a hoist for water conservancy and hydropower construction. Background Art

[0002] During the construction of water conservancy and hydropower projects, hoists are used to lift containers filled with construction materials to the usage location. Existing hoists are generally hooks. By hanging the container on the hook and then using a lifting device to lift it to the usage location, this method is fast and convenient. However, as the usage time increases, operators have found that since the hook is connected to the lifting device through a rope and itself has a certain degree of sway, when directly hanging a bucket or other container filled with construction materials on the hook and moving it through a lifting device, the sway amplitude during hoisting is even greater. This poses a risk that during hoisting, the hoisted container may slip off the hook and fall due to increased sway. If the opening of the hook is made smaller during manufacturing, although the risk of slipping can be reduced, due to the smaller opening of the hook, it will be very inconvenient to hang or remove the hanging object. Every time an operator hangs or removes an item, it is very laborious, increasing the labor intensity of the operator. Moreover, since the opening still exists, the risk of slipping cannot be completely eliminated, and there are still certain potential safety hazards.

[0003] Therefore, those skilled in the art are committed to providing a hoist for water conservancy and hydropower construction that can effectively solve the above technical problems. Summary of the Utility Model

The rear half of the swing rod 20 is detachably connected to the front half of an adjusting cylinder 21. The rear half of the adjusting cylinder 21 extends out of the adjusting cavity 12; A lifting ring 22 is arranged at the upper end of the positioning seat 3.

[0032] The housing 1 includes a front housing 23 and a rear housing 26. The front housing 23 and the rear housing 26 are simultaneously detachably connected to the positioning seat 3 through a plurality of bolts 27. First notches 2 are formed on both the front housing 23 and the rear housing 26. Both ends of the rotating seat 6 are respectively rotatably connected to the front housing 23 and the rear housing 26; Both ends of the limiting column 8 are respectively connected to the inner walls of the front housing 23 and the rear housing 26.

[0033] The positioning seat 3 includes an upper positioning portion 28 and a lower positioning portion 29;

[0034] The rotating seat 6 is rotatably arranged in the lower positioning portion 29. The second notch 5 is formed in the lower positioning portion 29. The installation cavity 11 is formed in the upper half of the lower positioning portion 29 and extends into the upper positioning portion 28. The adjustment cavity 12 is formed in the upper positioning portion 28.

[0035] Two sliding grooves 30 are symmetrically formed in the inner wall of the installation cavity 11. Sliders 31 are arranged on both sides of the sliding seat 15, and each slider 31 is slidably located in each sliding groove 30.

[0036] The sliding seat 15, the upper limit seat 16 and the lower limit seat 17 are of an integrally formed structure. A guiding hole 32 is formed at the upper end of the upper limit seat 16, and the upper limit seat 16 is slidably sleeved on the guiding column 18 through the guiding hole 32.

[0037] A cylinder 33 is arranged at the rear end of the swing rod 20;

[0038] A sleeve 35 is arranged at the front end of the adjusting cylinder 21, and the adjusting cylinder 21 is detachably inserted on the cylinder 33 through the sleeve 35.

[0039] A hanging ring 37 is arranged on the adjusting cylinder 21. Hooks 38 are arranged on the outer walls of the front shell 23 and the rear shell 26, and the adjusting cylinder 21 can be hung on the hooks 38 through the hanging ring 37.

[0040] A handle 39 is arranged on the rotating seat 6. An observation hole 50 is formed in the rear shell 26. A coating groove 51 is formed at the front end of the lower limit seat 17, and a red coating for cooperating with the observation hole 50 is coated in the coating groove 51.

[0041] The optimal working principle of the present utility model is as follows:

[0042] Insert the sleeve 35 of the adjusting cylinder 21 onto the cylinder 33. Press down the swing rod 20 so that the swing rod 20 pushes the upper limit seat 16 upwards. As the upper limit seat 16 moves upwards, the sliding seat 15 and the lower limit seat 17 move upwards accordingly. As the lower limit seat 17 moves upwards, the lower half of the lower limit seat 17 disengages from the positioning port 10. At this time, the lower limit seat 17 no longer limits the rotating seat 6. Then, the rotating seat 6 can be rotated. As the rotating seat 6 rotates, the hanging port 9 rotates towards the first notch 2 and the second notch 5. Subsequently, a lifting rope or a hanging ring can be hung at the hanging port 9. The lifting rope or the hanging ring is connected to the object to be hung (a bucket or other container). According to actual needs (if the object to be hung is easy to hang), it is also possible to directly hang the object to be hung at the hanging port 9 without using the lifting rope and the hanging ring. Then, rotate the rotating seat 6 back (at this time, since the hanging object is still placed on the ground, the rotating seat 6 does not bear the weight of the hanging object, so it is convenient to rotate and adjust the rotating seat 6) until the limit post 8 limits the rotation of the rotating seat 6 by cooperating with the arc-shaped guiding port 7 and it can no longer be rotated. At this time, the positioning port 10 is exactly located directly below the installation cavity 11 and is connected to the installation cavity 11, and the hanging port 9 is sealed by the positioning seat 3 to prevent the hanging object from falling off. Then, stop applying pressure to the swing rod 20 and lift it upwards. At the same time, cooperate with the resilience of the spring 19 to make the lower limit seat 17 fall into the positioning port 10, thereby limiting the rotating seat 6. The hanging ring 22 is connected to a lifting device (not shown in the figure). Finally, use the lifting device (prior art, a crane or other lifting equipment) to lift it to the place of use. After being lifted to the place of use, lower it through the lifting device until the lifted object is placed on the ground. The rotating seat 6 no longer receives the downward pressing force of the weight of the lifted object itself. Thus, when removing the lifted object, it is convenient for the lower limit seat 17 to move upwards.

[0043] Preferably, when the lower limit seat 17 falls into the positioning port 10, the operator checks at the observation hole 50. If the red coating can be seen, it means that the clamping is in place.

[0044] In addition, the resilience of the spring 19 applies a downward pressure to the sliding seat 15 to improve the stability of the lower limit seat 17 in the positioning port 10. At the same time, the sliding seat 15, the upper limit seat 16 and the lower limit seat 17 in the present utility model are of an integrally formed structure, and their overall weight is greater than the weight of the swing rod 20. Thus, even without the spring 19, the swing rod 20 itself cannot push the sliding seat 15, the upper limit seat 16 and the lower limit seat 17 upwards, effectively ensuring safety. And when lifting an object, the rotating seat 6 is squeezed, thus causing a pressing force on the lower limit seat 17, which will also prevent the slider from moving upwards.

[0045] After locking, by hanging the adjusting cylinder 21 on the hanging ring 37, the cylinder 33 is prevented from extending out of the adjusting cavity 12, thereby effectively avoiding the safety hazard caused by the swing of the swing rod 20 when the cylinder 33 is touched by an external object during the hanging process.

[0046] In actual use, the utility model is not limited to hanging barrel-shaped containers, nor is it limited to single use, and can be used in combination according to needs.

[0047] The preferred specific embodiments of the present invention have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present invention without creative work. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field of the present invention through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of the prior art should be within the protection scope determined by the claims.
