Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a biochemical pool maintenance hoisting device. Background Art

[0002] The biochemical pool is a treatment system that uses microorganisms to degrade organic matter. It is widely used in wastewater treatment and organic waste treatment. In underground sewage treatment plants, the biochemical pool and the equipment used in the biochemical pool are all set underground, such as submersible flow propellers, water pumps, agitators, etc.

[0003] In the sewage treatment process, the biochemical pool plays an important role in the early stage. The flow promoter and agitator in the pool have a high failure rate due to design structure and sealing problems. The equipment is often lifted out of the biochemical pool for dismantling and replacement of its accessories.

[0004] The problem with the prior art is that since the equipment is distributed at various points of the biochemical pool, if lifting equipment is installed at each location, it will occupy ground space. Therefore, the prior art adopts a method of temporarily setting up a tripod, installing a hand chain hoist on the tripod, and then using the hand chain hoist to lift the equipment.

[0005] However, this traditional method is not only very cumbersome to assemble the tripod and hand winch each time, but also the strength of this assembly structure is insufficient when facing heavy equipment.

[0006] Moreover, during the lifting process, it is necessary to adjust the horizontal distance and angle according to the lifting posture and state of the equipment to avoid collision during the lifting process, and to lock the position after adjustment to prevent the hoisted object from moving horizontally again. However, traditional hand chain hoists and tripods do not have such functions.

[0007] Therefore, it is necessary to design a biochemical pool maintenance lifting device that is easy to operate, capable of lateral adjustment and locking. Utility Model Content

[0008] In order to solve the deficiencies of the above-mentioned technology, the utility model provides a biochemical pool maintenance hoisting device.

[0009] The utility model is further provided with: a biochemical pool maintenance hoisting device, comprising a mobile gantry, a single-beam crane, a lifting mechanism, and a hand chain hoist, the mobile gantry comprising a crossbeam portion, and support frames arranged on both sides of the crossbeam portion, the bottom of the support frame is provided with a universal wheel, the crossbeam portion is provided with a slide rail groove along the length direction, the single-beam crane reciprocates along the slide rail groove, the lifting mechanism is arranged at the single-beam crane, and reciprocates with the single-beam crane;

[0010] The support frame is provided with a hanging hole, and the hand chain hoist is detachably fixedly connected to the hanging buckle. The hand chain hoist includes a lifting chain and a first hook. The first hook is hooked with the single-beam crane, and the lifting chain drives the single-beam crane to move, position and lock.

[0011] The utility model is further configured as follows: the lifting mechanism comprises a hand winch, a lifting sling, a first guide wheel, a second guide wheel, a third guide wheel and a second hook, the hand winch and the hand chain hoist are respectively arranged on the support frames on both sides of the beam, and the support frame where the hand winch is located is the first support frame;

[0012] The first support frame is provided with a wire groove extending from the outer side of the first support frame relative to the cross beam to the inner side vertically above the hand winch. The hand winch is arranged on the outer side of the first support frame. A first wheel seat is arranged at the notch on the outer side of the wire groove. A second wheel seat is arranged on the end face of the cross beam near the wire groove. A third wheel seat is arranged on the traveling crane. The first, second and third guide wheels are respectively axially fixedly matched with the first, second and third wheel seats in circumferential rotation. One end of the lifting rope is fixedly connected to the hand winch, and the other end passes through each guide wheel and is fixedly connected to the second hook.

[0013] The utility model is further configured as follows: a fall arrester is arranged on the single-beam crane, and the fall arrester is provided with a third hook.

[0014] The beneficial effects of the utility model are as follows: Figure 3 As shown, the ratchet and friction plate of the hand chain hoist cooperate with the lifting chain and the hand chain hoist to drive the single-beam crane to move, and the ratchet structure, the hand chain hoist and the hanging hole are fixed to form a limiting pulling force F1 on one side of the single-beam crane.

[0015] The other side of the single-beam crane cooperates with the lifting and hoisting of the hand winch. One end of the lifting rope is fixedly connected to the hand winch, and the other end passes through each guide wheel and is fixedly connected to the second hook. When the equipment is hoisted, a Figure 3 Under the action of F2 and with the guidance of each guide wheel, the single-beam crane moves toward Figure 3 The left side moves in the opposite direction, which creates a balance with the pulling force F1 on the right side. That is, in the hoisting state, the single-beam crane can keep the position of the crossbeam fixed. By retracting and extending the lifting chain of the hand winch, the reciprocating position adjustment of the single-beam crane can be controlled, thereby driving the position and posture adjustment of the hoisted object.

[0016] At the same time, the hand winch is set on the outside of the gantry, which is easy to operate and away from the hoisted object to ensure safety.

[0017] In further settings, a fall arrester is installed on the single-beam crane. When an accident occurs during operations under the pool, hanging the fall arrester when hoisting people on the gantry for emergency rescue can serve as an additional safety protection.
