Description

Technical Field

[0001] The invention belongs to the field of water pump devices, and in particular relates to a water pump lifting auxiliary traction device. Background Art

[0002] A water pump is placed in a sewage pool 15 meters away from the ground. The water pump works continuously in the sewage pool. A lifting ring is provided above the water pump, and the distance between the lifting ring and the ground is 12 meters. Since the water pump needs to be lifted to the ground frequently for maintenance, and the underwater situation cannot be observed visually, the existing operation is to lift it with a crane with a hook. First, an application is made to reduce the water intake to lower the liquid level in the water pump room, and then a diver holds the hook and dives into the sewage pool to explore the position of the lifting ring and hang the hook securely.

[0003] The operation was extremely difficult for the divers as the underwater visibility was low and other water pumps in the same pool were in a continuous pumping state and could not be stopped. The total time from applying to reduce the water intake, preparing the diving equipment, operating in the water to successfully lifting the water pump exceeded 24 hours. It was also very dangerous and prone to accidents. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a water pump lifting auxiliary traction device to solve the problems that the prior art water pump lifting requires manual operation, has a high risk factor, and takes a long time to operate.

[0005] The present invention is achieved through the following technical solutions.

[0006] The auxiliary traction device for lifting a water pump includes a bracket, a lifting rope, a hook and a water pump lifting ring. The tail end of the lifting rope is connected to the lifting hook. The bracket is installed on the ground. The two ends of the bracket are provided with traction shafts. The traction rope is provided outside the traction shaft. The hook is fixed with an auxiliary hook. One end of the traction rope is fixed to the tail end of the auxiliary hook, and the other end is fixed to the head end of the auxiliary hook. The traction rope also passes through the water pump lifting ring. The traction rope forms an inverted triangle under the action of the two traction shafts and the water pump lifting ring. The traction rope on the traction shaft is adjusted so that the traction rope rotates around the traction shaft, and the hook is hung on the lifting ring under the rotation of the traction rope. There is no need to apply for water inlet reduction, no need for divers to dive into the water, and no need to spend a lot of time on preparation work. It only needs to manually adjust the position of the traction rope on the ground to meet the change of the position of the hook so that it finally enters perpendicular to the water pump lifting ring, and it can be tested many times until the water pump lifting ring is hooked.

[0007] Preferably, the auxiliary hook comprises a tail end fixing portion and a front end extension portion, and a curved bracket is connected between the tail end fixing portion and the front end extension portion. The curved bracket is also close to the hook and also has a partial fixing function.

[0008] Preferably, the tail end fixing part includes two clamping blocks, and the clamping blocks are provided with threaded connection holes, one for firmly sleeve the auxiliary hook on the hook, and the other for serving as the rear end tying point of the traction rope.

[0009] Preferably, the front end extension is inclined and is wrapped and fixed by an annular wrapping seat. First, the angle at which the lifting ring enters the hook is increased, and second, the annular wrapping seat serves as a front tying point of the traction rope.

[0010] Preferably, a safety buckle is hingedly provided on the hook, and the safety buckle cooperates with the protrusion inside the hook, and the safety buckle can only rotate toward the inside of the hook and cannot be separated from the protrusion of the hook, so as to play a protective role. If the hook is separated during the lifting process, it is very dangerous.

[0011] Preferably, the curved support is attached to both sides of the hook, and its width is smaller than the width of the hook, so as not to allow the curved support to be stressed during the lifting process.

[0012] Preferably, the two clamping blocks of the tail end fixing portion are screwed together with bolts, and the traction rope is tied to the bolts.

[0013] As a preferred embodiment, the annular wrapping seat is annular, wraps the hook, and the traction rope is tied to the bolt of the front end extension. Both binding points are on the auxiliary hook to prevent the hook from deforming.

[0014] Compared with the prior art: the rotation and forward and backward movement of the traction rope can be manually adjusted on the ground, and the angle of the hook can be adjusted in all directions, so that the hook is hung on the lifting ring under the rotation and left and right movement of the traction rope.

[0017] The auxiliary traction device for lifting a water pump comprises a bracket 1, a lifting rope 4, a hook 7 and a water pump lifting ring 5, wherein the tail end of the lifting rope 4 is connected to the lifting hook 7, the bracket 1 is installed on the ground, traction shafts 2 are arranged at both ends of the bracket 1, a traction rope 3 is arranged outside the traction shaft 2, an auxiliary hook 6 is fixedly arranged on the hook 7, one end of the traction rope 3 is fixed to the tail end of the auxiliary hook 6, and the other end is fixed to the head end of the auxiliary hook 6, the traction rope 3 also passes through the water pump lifting ring 5, the traction rope 3 forms an inverted triangle under the action of the two traction shafts 2 and the water pump lifting ring 5, the traction rope 3 on the traction shaft 2 is adjusted so that the traction rope 3 rotates around the traction shaft 2, and the hook 6 is hung on the lifting ring 5 under the rotation of the traction rope 3, the auxiliary hook 6 comprises a tail end fixing portion 61 and a front end extension The extension part 63, the curved bracket 62 is connected between the tail end fixing part 61 and the front end extension part 63, the tail end fixing part 61 includes two clamping blocks, the clamping blocks are provided with threaded connection holes, the front end extension part 63 is inclined, and is wrapped and fixed by an annular wrapping seat 64, and the hook 7 is also hingedly provided with a safety buckle 8, the safety buckle 8 cooperates with the protrusion inside the hook 6, the safety buckle 8 can only rotate toward the inside of the hook 6, and cannot be separated from the protrusion of the hook 6, the curved bracket 62 is attached to both sides of the hook 7, and its width is smaller than the width of the hook 7, the two clamping blocks of the tail end fixing part 61 are screwed together with bolts, the traction rope 3 is tied to the bolts, the annular wrapping seat 64 is annular, wraps the hook 7, and the traction rope 3 is tied to the bolts of the front end extension part 63. .

[0018] A traction rope 3 is pre-threaded on the water pump lifting ring 5, and two points for fixing the traction rope 3 are extended in front and behind the lifting hook 7 through the auxiliary hook 6, one point is located at the tail end of the auxiliary hook 6, and the other point is located at the head end of the auxiliary hook 6. The traction rope 3 forms an inverted triangle under the action of the two traction shafts 2 and the water pump lifting ring 5.

[0019] During use, the lifting rope 4 brings the lifting hook 7 down, and during the descending process, the position of the traction rope 3 is constantly adjusted manually. The traction rope 3 can rotate clockwise around the traction shaft 2, or counterclockwise around the traction shaft 2. The traction rope 3 can also be adjusted forward and backward on the bracket 1, and move along the axial direction of the traction shaft 2. The bracket is in an upper square shape in space, and the traction shaft 2 is a part of the bracket.

[0020] During the adjustment process, there is always a position where the front end extension 63 is perpendicular to the water pump lifting ring 5. Due to the existence of the front end extension 63, the opening of the hook 7 becomes larger, and the front end extension 63 has a large inclination angle, which makes it easier to hook the lifting ring 5. When the front end extension 63 enters the lifting hook 7, one end of the safety buckle 8 is subjected to force and rotates toward the inside of the lifting hook 7, so that the water pump lifting ring 5 smoothly enters the inside of the lifting hook 7.

[0021] After the water pump lifting ring 5 smoothly enters the inner side of the lifting hook 7, the safety buckle 8 returns to its initial state due to its own gravity, and abuts against the protrusion on the inner side of the lifting hook 6 to prevent the water pump lifting ring 5 from escaping.

[0022] You can try several times. When the water pump lifting ring 5 smoothly enters the inner side of the hook 7, observe the change in the state of the traction rope 3, from a slightly loose state to a tightened state, and perform slight lifting several times. When the lifting reading on the crane changes, continue to lift the lifting rope 4.

[0023] At this time, the lifting rope 4 brings the lifting hook 7 up, and during the rising process, the lifting hook 7 is subjected to force, and the curved bracket 62 is attached to both sides of the lifting hook 7, and its width is smaller than the width of the lifting hook 7, so the auxiliary hook 6 will not be subjected to any pulling force.

[0024] The auxiliary hook 6 can be fixed on the hook 7 mainly relying on two points of action, one is the clamping force given to it by the two clamping blocks of the tail end fixing part 61, and the other is the wrapping friction force given by the annular wrapping seat 64.

[0025] The protection scope of the present invention includes but is not limited to the above embodiments. The protection scope of the present invention shall be based on the claims. Any replacement, deformation, and improvement of the technology that can be easily thought of by technicians in this field shall fall within the protection scope of the present invention.
