Description

Technical Field

[0001] The utility model relates to the technical field of hoisting equipment, in particular to a sewage pipe hoisting device. Background Art

[0002] During the processes of laying, stacking and transporting, it is necessary to hoist the sewage pipes.

[0003] In the prior art, the sewage pipes are usually hoisted by means of wire ropes or sling bundling. Before hoisting, it is necessary to pass the sling through the bottom of the sewage pipe, then hang the end of the sling on the hook. After hoisting in place, the sling is separated from the hook, and then the sling is drawn out from the bottom of the sewage pipe. The labor intensity of the staff is high, and such frequent repetitive labor easily causes the staff to be extremely fatigued. Moreover, there are certain potential safety hazards during the operation: for example, if the sewage pipe rolls, it is easy to hit or crush the staff; if the hook is injured by the accidental fracture of the wire rope, it will injure the staff.

[0004] Therefore, it is necessary to develop a sewage pipe hoisting device for the above-mentioned defects. Content of the Utility Model

[0005] The purpose of the utility model is to provide a sewage pipe hoisting device, which can reduce the labor intensity of the staff and improve the safety of the hoisting process.

[0028] In a specific embodiment of the present utility model, as Figures 1 to 3 shown, it includes a hanger assembly, and two U-shaped frames 1 are fixedly connected below the hanger assembly. The two U-shaped frames 1 are arranged symmetrically at intervals, and each U-shaped frame 1 is provided with a clamping assembly for clamping the sewage pipe;

[0029] The clamping assembly includes two symmetrically arranged pliers arms 3, and the two pliers arms 3 are slidably connected to the cross beam 101 of the U-shaped frame 1;

One end of the two-link mechanism is hinged to the top end of the pliers arm 3, and the other end of the two-link mechanism is hinged to the U-shaped frame 1;

[0031] The clamping assembly includes a horizontally arranged lifting beam 4, and the lifting beam 4 is slidably connected to the two-link mechanism;

[0032] The telescopic cylinder 5 is also included, and the telescopic cylinder 5 is fixedly connected to the hanger assembly, and the telescopic end of the telescopic cylinder 5 is fixedly connected to the lifting beam 4. The lifting beam 4 and the vertical beam of the U-shaped frame 1 can be connected (i.e., they can be in sliding contact) or not connected (i.e., there is a gap between them), as long as it does not affect the normal lifting of the lifting beam 4.

[0033] The clamp arm 3 includes an arc segment 301 and a straight segment 302. The arc segment 301 and the straight segment 302 are integrally formed. The openings of the two arc segments 301 located on the same U-shaped frame 1 are arranged opposite to each other. The crossbeam 101 includes two channel steels arranged symmetrically at intervals, and the openings of the two channel steels are arranged opposite to each other. The straight segment 302 is arranged between the two channel steels. Bumps 303 are fixed on both sides of the straight segment 302. The bumps 303 are located in the openings of the corresponding channel steels, and the bumps 303 are slidably matched with the channel steels. The straight segment 302 protrudes out of the upper surface of the crossbeam 101 and is hinged to the two-link mechanism.

[0034] The two-link mechanism includes a sleeve 8 and a first link 6 and a second link 7 arranged in an eight-shaped shape. The top of the first link 6 is hinged to the side wall of the sleeve 8, the bottom of the first link 6 is hinged to the vertical beam corresponding to the U-shaped frame 1, the top of the second link 7 is hinged to the side wall of the sleeve 8 away from the first link 6, and the bottom of the second link 7 is hinged to the top of the straight section 302; the lifting beam 4 is slidably connected to the sleeve 8. Figure 1 As shown, when the clamp arm 3 is in the open state, the angle between the first connecting rod 6 and the vertical beam corresponding to the U-shaped frame 1 is preferably greater than or equal to 45°, and the angle between the first connecting rod 6 and the second connecting rod 7 is greater than or equal to 45°. In this way, when the lifting beam 4 is lifted or lowered, it is convenient for the first connecting rod 6 and the second connecting rod 7 to swing and for the component force of the first connecting rod 6 to drive the sliding sleeve 8 to slide, thereby facilitating the component force of the second connecting rod 7 to drive the clamp arm 3 to slide.

[0035] The sliding sleeve 8 is sleeved on the lifting beam 4 , and the sliding sleeve 8 and the lifting beam 4 are slidably matched.

[0036] The hanger assembly includes a first plate body 9 and a second plate body 10, which are arranged at intervals up and down, and a plurality of support rods 2 are fixedly connected between the first plate body 9 and the second plate body 10; a U-shaped frame 1 is fixedly connected to the lower surface of the first plate body 9, and a lifting ring 1001 is fixedly connected to the upper surface of the second plate body 10. The lifting ring 1001 is used to connect with the hook.

[0037] The telescopic cylinder 5 is located between the first plate body 9 and the second plate body 10 . The telescopic cylinder 5 is fixedly connected to the upper surface of the first plate body 9 . The telescopic end of the telescopic cylinder 5 slides through the first plate body 9 and is fixedly connected to the lifting beam 4 .

[0038] The telescopic cylinder 5 specifically adopts an electric telescopic cylinder. Obviously, the telescopic cylinder 5 can also be a hydraulic telescopic cylinder or a pneumatic telescopic cylinder.

[0039] The working principle of a sewage pipe hoisting device of the present utility model: Figure 1 As shown, when the clamping arms 3 are in the open state, the telescopic end of the telescopic cylinder 5 extends, driving the lifting beam 4 to descend. The lifting beam 4 drives the sliding sleeve 8 to descend. At the same time, the top end of the first connecting rod 6 swings downward and drives the sliding sleeve 8 to slide towards the middle of the lifting beam 4. The second connecting rod 7 swings and its bottom end drives the clamping arms 3 to slide towards the middle of the cross beam 101. Then, the two clamping arms 3 on the same U-shaped frame 1 approach each other, and thus the arc-shaped section 301 of the clamping arms 3 clamps the sewage pipe. After the hoisting is in place, the telescopic end of the telescopic cylinder 5 contracts, driving the lifting beam 4 to rise. At the same time, the top end of the first connecting rod 6 swings upward and drives the sliding sleeve 8 to slide towards the end of the lifting beam 4. The second connecting rod 7 swings and its bottom end drives the clamping arms 3 to slide towards the end of the cross beam 101. Then, the two clamping arms 3 on the same U-shaped frame 1 move away from each other, and thus the arc-shaped section 301 of the clamping arms 3 releases the sewage pipe.

[0040] In this specification, each embodiment is described in a progressive manner. The key point of each embodiment is to illustrate the differences from other embodiments. The same or similar parts among the embodiments can be referred to each other, and the embodiments can be combined with each other.
