Description

Technical Field

[0001] The utility model belongs to the production technical field of well covers and relates to a well cover transfer component. Background Art

[0002] Well covers are used to cover roads or deep wells at home to prevent people or objects from falling. They can be classified into metal well covers, high-strength fiber cement concrete well covers, resin well covers, etc. Generally, they are circular in shape. They can be used in green belts, sidewalks, motor vehicle lanes, docks, alleys, etc.

[0003] Among them, the sewage ditch cover is one form of well cover, which usually includes a rectangular body with a plurality of long strip-shaped water inlet holes formed thereon. During the production process of the sewage ditch cover, one step is to hang the sewage ditch cover on a suspension hook. Then, under the driving action of a chain and a guide rail, the sewage ditch cover is first moved to a paint dipping place and immersed in paint. After that, the sewage ditch cover continues to be moved by the suspension hook and dried, so that a protective layer can be formed on the surface of the sewage ditch cover. At present, when workers hang the sewage ditch cover on the suspension hook, they directly manually move the sewage ditch cover and then hang a certain hole on the sewage ditch cover on the suspension hook. However, due to the certain thickness and volume of the sewage ditch cover, if workers hang the sewage ditch cover far away from their bodies on the suspension hook, they can obtain a better view and it is convenient for hanging. However, due to the certain mass of the sewage ditch cover (metal), the operation intensity is relatively high; but if workers hold the sewage ditch cover relatively close to their bodies, although it will be labor-saving, the view is poor and they cannot accurately hang the sewage ditch cover on the suspension hook; thus, whether the sewage ditch cover is close to or far from the body, the operation effect is poor. Content of the Utility Model

[0005] To solve the above technical problems, the utility model provides a well cover transfer component, which includes a first hanging rod, a second hanging rod and a third hanging rod connected in sequence. The first hanging rod, the second hanging rod and the third hanging rod form a U shape, and the length of the first hanging rod is greater than that of the third hanging rod. A U-shaped clamping part is arranged at the free end of the third hanging rod, and the opening of the clamping part faces the second hanging rod. A hanging cable is arranged at the free end of the first hanging rod, an operating column is arranged at the free end of the hanging cable, and an annular hanging ring is arranged at the free end of the operating column;

[0006] When a manhole cover is transferred, the middle part of the hanging cable is inserted into the opening of the inserting part, and the hanging cable, the first hanging rod, the second hanging rod and the third hanging rod form a ring, and the first hanging rod and the third hanging rod pass through two adjacent water inlet holes on the manhole cover, the second hanging rod and the hanging cable are respectively located on the inner and outer sides of the manhole cover, the operating column and the hanging ring are both located on the outside of the manhole cover, and the width of the inserting part is smaller than the width of the water inlet hole.

[0007] The utility model is further configured that an anti-dropping ball is arranged in the middle of the hanging cable, the diameter of the anti-dropping ball is larger than the opening of the clip-in portion, and the anti-dropping ball abuts against a side of the clip-in portion away from the first hanging rod.

[0008] The utility model is further configured such that a termination plate is provided on the outer wall of the first hanging rod, the termination plate is attached to the outer side of the manhole cover, and the diameter of the termination plate is greater than the width of the water inlet hole.

[0009] The utility model is further configured such that an anti-slip disk is provided at the free end of the first hanging rod, a rotating circle is rotatably provided on the outer wall of the first hanging rod located between the anti-slip disk and the termination disk, the outer wall of the first hanging rod is fitted to the inner side of the rotating circle, and one end of the hanging cable is connected to the rotating circle.

[0010] The utility model is further configured that a terminating portion is provided on the lower side of the terminating plate, and the terminating portion is fitted to the inner wall of the corresponding water inlet hole.

[0011] The utility model is further configured such that an annular index finger ring and an L-shaped thumb push portion are provided on the upper side of the termination disk, the index finger ring and the thumb push portion are located on both sides of the anti-slip disk, the free end of the thumb push portion faces away from the third hanging rod, and the thumb push portion is located above the termination portion.

[0012] The utility model is further configured that an anti-skid disk having a diameter larger than that of the operating column is provided at the end of the operating column, and the suspension ring is connected to the outer side of the anti-skid disk.

[0013] The utility model is further configured that the suspension ring includes two parallel connecting parts and a circular arc-shaped suspension part connected between the two connecting parts, and the curvature of the suspension part is greater than 3π / 2.

[0014] The utility model is further configured to include a J-shaped lifting member, wherein the shorter end of the lifting member passes through a water inlet hole, and the longer end is provided with an annular lifting ring, and the lifting member and the first hanging rod are located at opposite corners of the manhole cover.

At this time, the worker can lift the manhole cover upward through the operating column, and at the same time, the worker applies the other hand to another water inlet hole. In this way, the manhole cover can be lifted and moved with both hands; when hanging the manhole cover on the suspension hook, since the suspension ring is located outside the manhole cover, even if the manhole cover is relatively close to the body during the process of the worker carrying the manhole cover, the worker can still conveniently hang the suspension ring on the suspension hook; that is, at this time, the manhole cover is relatively close to the body, so the handling intensity is small. Secondly, since the suspension ring is located outside the manhole cover and has a certain degree of mobility (the hanging cable can undergo a certain degree of deformation), the suspension ring can be conveniently hung on the suspension hook, and the overall operation effect is better.

[0029] A termination disk 9 is provided on the outer wall of the first hanging rod 1. The termination disk 9 is attached to the outside of the manhole cover, and the diameter of the termination disk 9 is greater than the width of the water inlet hole.

[0030] A anti - detachment disk 10 is provided at the free end of the first hanging rod 1. A rotating ring 11 is rotatably provided on the outer wall of the first hanging rod 1 between the anti - detachment disk 10 and the termination disk 9. The outer wall of the first hanging rod 1 is attached to the inner side of the rotating ring 11. One end of the cable 5 is connected to the rotating ring 11.

[0031] A termination part 12 is provided below the termination disk 9. The termination part 12 is attached to the inner wall of the corresponding water inlet hole.

[0032] An annular index finger ring 13 and an L - shaped thumb pushing part 14 are provided above the termination disk 9. The index finger ring 13 and the thumb pushing part 14 are located on both sides of the anti - detachment disk 10. The free end of the thumb pushing part 14 faces away from the third hanging rod 3. The thumb pushing part 14 is located above the termination part 12.

[0033] An anti - slip disk 15 with a diameter larger than that of the operating column 6 is provided at the end of the operating column 6. The suspension ring 7 is connected to the outside of the anti - slip disk 15.

[0034] The suspension ring 7 includes two parallel connecting parts 7a and an arc - shaped hanging part 7b connected between the two connecting parts 7a. The radian of the hanging part 7b is greater than 3π / 2.

[0035] It also includes a J - shaped lifting piece 16. The shorter end of the lifting piece 16 passes through a water inlet hole, and the longer end is provided with an annular lifting ring 17. The lifting piece 16 and the first hanging rod 1 are located at the diagonals of the manhole cover.

[0036] A protective arm 18 is provided in the middle of the lifting piece 16. The free end of the protective arm 18 is provided with a rectangular protective plate 19. The width and length of the protective plate 19 are both greater than the width of the water inlet hole. The protective plate 19 abuts against the upper side of the manhole cover.

[0037] A manhole cover transfer assembly provided by the utility model. When painting and drying a manhole cover (preferably applicable to a sewage ditch cover), a worker first holds the first hanging rod 1 and rotates it so that the plane where the first hanging rod 1, the second hanging rod 2, and the third hanging rod 3 are located is parallel to one of the water inlet holes. At this time, the first hanging rod 1, the second hanging rod 2, and the clamping part 4 can be inserted through the water inlet hole from top to bottom. When the first hanging rod 1 is lower than the manhole cover body, rotate the first hanging rod 1 by 90 degrees so that the third hanging rod 3 rotates to the lower part of the adjacent water inlet hole, and then raise the first hanging rod 1 so that the clamping part 4 passes through the adjacent water inlet hole and is higher than the manhole cover body. Then the worker moves the operating column 6 so that the middle part of the hanging cable 5 is clamped into the clamping part 4 through the opening at the bottom of the clamping part 4. Then move the operating column 6 towards the outside of the manhole cover body. At this time, the worker can lift the manhole cover upwards through the operating column 6, and at the same time, the worker applies the other hand to another water inlet hole. In this way, the manhole cover can be lifted and moved with both hands. When hanging the manhole cover on the suspension hook, since the suspension ring 7 is located outside the manhole cover, even when the worker is carrying the manhole cover, the manhole cover is relatively close to the body. At this time, the worker can conveniently hang the suspension ring 7 on the suspension hook. That is, at this time, the manhole cover is relatively close to the body, so the handling intensity is small. Secondly, since the suspension ring 7 is located outside the manhole cover and has a certain degree of mobility (the hanging cable 5 can undergo a certain degree of deformation), the suspension ring 7 can be conveniently hung on the suspension hook, and the overall operation effect is better.

[0038] During actual operation, the worker passes the right index finger through the index finger ring 13, and the right thumb is stuck in the thumb pushing part 14. In this way, the first hanging rod 1 can be moved through the index finger and the thumb, and the second hanging rod 2, the third hanging rod 3, and the clamping part 4 can all be moved to appropriate positions. When the second hanging rod 2, the third hanging rod 3, and the clamping part 4 are all moved to the lowest height, the stop disk 9 just touches the top of the manhole cover at this time, that is, the stop disk 9 makes the operation of moving the first hanging rod 1 more convenient. Then the index finger hooks the index finger ring 13, and the thumb pushes the thumb pushing part 14 in the direction away from the palm. At this time, the first hanging rod 1 can be rotated, and when the stop part 12 touches the inner wall of the corresponding water inlet hole, it means that the angle of the first hanging rod 1 has been rotated to the appropriate position at this time. Then, the first hanging rod 1 is lifted upwards through the index finger ring 13 and the thumb pushing part 14 so that the second hanging rod 2 touches the lower side of the manhole cover. During the above operation process of this section, the worker holds the operating column 6 with the left hand, and after the second hanging rod 2 touches the manhole cover, the left hand moves the operating column 6 so that the hanging cable 5 is clamped into the clamping part 4 through the bottom bayonet of the clamping part 4. At the same time, the hanging cable 5 undergoes a slight deformation, so that the anti - detachment ball 8 can move to touch the side of the clamping part 4 away from the first hanging rod 1 (and then can maintain the position of part of the hanging cable 5). At this time, the right thumb of the worker is removed from the thumb pushing part 14, the index finger is withdrawn from the index finger ring 13, and the right hand takes over the operating column 6.

[0039] Then, after the worker passes his left hand through the lifting ring 17 (which is usually carried on the worker's body through a belt or the like), he moves the lifting member 16 through the lifting ring 17 and passes the bent portion of the lifting member 16 through one of the water inlet holes. The water inlet hole through which the lifting member 16 passes and the water inlet hole through which the first hanging rod 1 passes are preferably two diagonally opposite holes on the manhole cover, which facilitates moving the manhole cover.

[0040] When the lifting member 16 passes through the water inlet hole, at this time, the worker's two hands, one of which operates the lifting ring 17 and the other operates the operating column 6. And the left hand (i.e., the hand operating the lifting ring 17) mainly bears the mass of the manhole cover, and the right hand is used to control the angle of the manhole cover and to put the hanging ring 7 onto the suspension hook, making the operation smoothness relatively high. During the operation process, if the worker makes a mistake in operation and causes the left hand to have a tendency to hit the manhole cover, at this time, the protection plate 19 will first come into contact with the manhole cover, so that the left hand and the manhole cover are continuously kept in a separated state, playing a protective role for the operator. At the same time, the width and length of the protection plate 19 are both larger than the width of the water inlet hole, so that the protection plate 19 can always act on the upper side of the manhole cover, and its effect can continue to exist.

[0041] When the worker's right hand operates the operating column 6, the anti-slip disk 15 at the top can preferably prevent relative sliding between the operating column 6 and the right hand, reducing the operation difficulty. At the same time, the hanging ring 7 includes a connecting portion 7a and a hanging portion 7b, and the arc of the hanging portion 7b is relatively large, so that the opening size of the hanging ring 7 is enlarged, making it better to hang with the suspension hook.

[0042] Among them, after the manhole cover in this application is produced, it is usually in a stack state and is moved to the corresponding work station using a pallet. Among a stack of manhole covers, the body of each one is a cover shape with the opening facing downwards, and the water inlet hole is located at the top of the body. So when moving the second hanging rod 2 etc. down to the lower side of the body, the shape of the body provides corresponding space for operation. At the same time, in the industry, there is also a structure that uses a J-shaped hook to hook the manhole cover and then suspends the ring at the top of the hook on the suspension hook. However, it is found in the use process that the manhole cover is prone to relative movement or even detachment from the hook, thus causing some accidents. But when using the structure of this application to move the manhole cover, it can fully ensure the connection stability between the moving structure and the first hanging rod 1 etc. At the same time, when this application is actually used, produced and sold, it can be either only the part of the first hanging rod 1 or the part of the first hanging rod 1 and the lifting member 16 as a whole.

[0043] The above description is only a description of the preferred embodiments of the present utility model, and does not impose any limitation on the scope of the present utility model. Any changes and modifications made by those of ordinary skill in the field of the present utility model according to the above disclosure shall fall within the protection scope of the claims.
