Description

Technical Field

[0001] This utility model relates to the field of lifting equipment, and in particular to a lifting device for sludge cleaning. Background Technology

[0002] When cleaning up sludge, it needs to be transported and centrally processed. Before transport, the buckets containing the sludge need to be lifted and loaded onto trucks. Existing lifting equipment can generally only lift a single bucket at a time, which is not efficient enough for the transfer. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a lifting device for sludge cleaning that can lift multiple buckets at once, maintain stability, and achieve high transfer efficiency.

[0004] The technical solution of this utility model is as follows:

[0005] A lifting device for sludge cleaning includes:

[0006] A lifting frame is inclinedly mounted on a base, and the top of the lifting frame is equipped with pulleys;

[0007] A winch is mounted on the base on the side facing away from the lifting frame. A steel cable is wound around the winch and is arranged to pass over the top side of the pulley.

[0008] The suspension frame includes a central rod, connecting rods, connecting cables, a first hook, and support rods. The central rod is vertically positioned at the end of the steel cable. The connecting rods include at least three rods, which are horizontally and evenly positioned at the top of the central rod. The connecting cables are vertically positioned at the bottom of the connecting rods. The first hook is located at the end of the connecting cables and is used to lift the bucket. The number of support rods is the same as that of the connecting rods. The support rods are horizontally and evenly positioned at the bottom of the central rod and are alternately arranged with the connecting rods, such that the first hook aligns with the gap between two adjacent support rods.

[0009] In a further technical solution, clamping structures for clamping the bucket are provided on both sides of the support rod.

[0010] In a further technical solution, the clamping structure includes a stop block, a clamping block, a connecting piece, and a rotating shaft. The stop block and the clamping block are set at an obtuse angle. The rotating shaft is located on both sides of the connection between the stop block and the clamping block. The connecting pieces are arranged in pairs in the middle of the support rod. The connecting pieces are provided with shaft holes for rotating connection of the rotating shaft. The stop block is located on the side of the connecting piece closer to the center rod, opposite to the clamping block.

[0011] In a further technical solution, the inner side of the clamping block is provided with clamping teeth.

[0012] In a further technical solution, the bottom side of the connecting rod is provided with an adjustment structure for adjusting the connecting cable along the length of the connecting rod.

[0013] In a further technical solution, the adjustment structure consists of multiple hooks spaced apart along the length of the connecting rod.

[0014] In a further technical solution, a reinforcing rod is provided between the bottom side of the central rod and the connecting rod.

[0015] In a further technical solution, the end of the steel cable is provided with a second hook, and the top of the central rod is provided with a hanging ring for connecting the second hook.

[0016] The beneficial effects of this utility model are:

[0017] 1. A lifting frame with multiple first hooks can carry multiple buckets of sludge at one time, improving the efficiency of transfer; the winch can raise and lower the steel cable on the lifting frame, driving the lifting frame and buckets to move and lift. When the buckets are lifted, they can be reliably placed between two adjacent support rods, maintaining relative stability and not easily shaking.

[0018] 2. When the bucket approaches the stop block, the clamping block can be rotated to move closer to the bucket. Before the stop block and the support rod come into contact, the greater the tendency of the bucket to approach the stop block, the more stable the clamping block is in holding the bucket, and the more stable the bucket is loaded on the hanger.

[0019] 3. The positions of the connecting cable and the first hook can be adjusted according to the size of the bucket, making it convenient to lift different buckets and helping the bucket to remain stable under the action of the support rod and clamping structure. Attached Figure Description

[0026] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0027] Example:

[0028] like Figures 1-2 As shown, a sludge cleaning lifting device includes a base 40, a winch 10, a lifting frame 20, and a hanger 30; the lifting frame 20 is inclined on the base 40, and a pulley 21 is provided on the top of the lifting frame 20; the winch 10 is located on the side of the base 40 that is inclined away from the lifting frame 20, and a steel cable 11 is wound on the winch 10, which passes over the top side of the pulley 21 and hangs vertically downward at its end;

[0029] The lifting frame 30 includes a central rod 31, connecting rods 32, connecting cables 33, a first hook 34, and support rods 35. The central rod 31 is vertically located at the end of the steel cable 11. The connecting rods 32 include three rods, which are horizontally and evenly located at the top of the central rod 31. To strengthen the connecting rods 32, a reinforcing rod 36 can be installed between the bottom sides of the central rod 31 and the connecting rods 32. The connecting cables 33 are vertically located at the bottom side of the connecting rods 32. The first hook 34 is located at the end of the connecting cables 33 and is used to lift the bucket 50. The number of support rods 35 is the same as that of the connecting rods 32. The support rods 35 are horizontally and evenly located at the bottom of the central rod 31 and are alternately arranged with the connecting rods 32, so that the first hook 34 aligns with the gap between two adjacent support rods 35. The position of the connecting cables 33 ensures that when the bucket 50 is lifted by the first hook 34, the bucket 50 tends to move towards the support rods 35, so that the bucket 50 always moves towards the support rods 35 on both sides when it is lifted.

[0030] The working principle of the above technical solution is as follows:

[0031] During use, the winch 10 lowers the steel cable 11 and the lifting frame 30, and the handles on the buckets 50 are respectively attached to the first hooks 34. After the three buckets 50 are attached, the winch 10 is operated to retract the steel cable 11, and the steel cable 11 on the other side of the lifting frame 20 is fixed to the lifting frame 30 and raised. During this process, the buckets 50 are close to the two adjacent support rods 35, so they are not easy to sway. After the buckets 50 are lifted, they can be raised to the designated position for unloading and loading. The sludge from the three buckets 50 can be lifted at one time for transfer, which is highly efficient.

[0032] In another embodiment, such as Figure 3As shown, the support rod 35 has clamping structures on both sides for clamping the bucket 50. The clamping structures include abutment 61, clamping block 62, connecting piece 63 and rotating shaft. Abutment 61 and clamping block 62 are set at an obtuse angle. The rotating shaft is set on the upper and lower sides of the connection between abutment 61 and clamping block 62. The connecting piece 63 is set in pairs, one above the other, in the middle of the support rod 35. The connecting piece 63 has a shaft hole for rotating the rotating shaft, so that the whole formed by abutment 61 and clamping block 62 can rotate relative to the connecting piece 63 through the rotating shaft. Abutment 61 is set on the side of connecting piece 63 closer to the center rod 31 relative to clamping block 62. In addition, clamping teeth 64 can be set on the inner side of clamping block 62 away from the rotating shaft. The clamping teeth 64 can increase the friction between the clamping block 62 and the bucket 50, making the bucket 50 less likely to slip and the clamping more stable.

[0033] The initial position of the clamping block 62 is close to the support rod 35, and the abutment block 61 is raised. When the bucket 50 moves towards the abutment block 61, the clamping block 62 can be rotated to move closer to the bucket 50 to clamp the bucket 50. Before the abutment block 61 abuts against the support rod 35, the greater the tendency of the bucket 50 to move towards the abutment block 61, the more stable the clamping block 62 is in clamping the bucket 50, further maintaining the stable loading of the bucket 50 on the hanger 30.

[0034] In another embodiment, such as Figure 4 As shown, the bottom side of the connecting rod 32 is provided with an adjustment structure for adjusting the connecting cable 33 along the length direction of the connecting rod 32. The adjustment structure can be a plurality of hooks 37 spaced apart along the length direction of the connecting rod 32. A connecting ring can be provided at the top of the connecting cable 33, which can be connected to the hooks 37. The depth of the hook 37 recess and the distance from the end of the hook 37 to the bottom side of the connecting rod 32 can be adjusted appropriately so that the connecting cable 33 is not easily separated from the hooks 37 during the lifting of the bucket 50.

[0035] The positions of the connecting cable 33 and the first hook 34 can be adjusted according to the size of the bucket 50, which makes it convenient to lift different buckets 50 and helps the bucket 50 to remain stable under the action of the support rod 35 and the clamping structure.

[0036] In another embodiment, such as Figure 1 As shown, the end of the steel cable 11 is provided with a second hook 12, and the top of the central rod 31 can be provided with a hanging ring to connect the second hook 12.

[0037] The hanger 30 can be detached separately from the steel cable 11, making the structure flexible.

[0038] In another embodiment, the base 40 can be any rotating platform in the prior art, which facilitates the turning of the lifting frame 20 and further enhances the flexibility of the lifting equipment.

[0039] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
