Description

Technical Field

[0001] This utility model relates to the field of dredging tools, specifically a telescopic sludge removal clamp. Background Technology

[0002] In the routine maintenance and emergency dredging of urban drainage systems, manholes, septic tanks, and other facilities, it is often necessary to remove blockages such as plastic bags, cloth, branches, and stones. These blockages are usually located in narrow, deep wells, or inside pipe outlets, making manual retrieval difficult, inefficient, and posing safety hazards.

[0003] Currently, common dredging tools include long-handled hooks and rakes. While these tools extend the operational range to some extent, they still have many shortcomings:

[0004] Due to the limitation of the extension rod length, its working depth cannot reach the bottom of the well; if the extension rod length is extended, the strength of the extension rod also needs to be considered, and conventional hooking and rakeing methods are prone to causing the blockage to fall off. Utility Model Content

[0005] To address the technical problems existing in the background art, this utility model provides a telescopic sludge removal clamp with an adjustable extension rod length; a clamping force sufficient to grasp sludge; a locking mechanism to prevent the grasped sludge from falling off; and convenient opening and closing.

[0006] The technical solution adopted by this utility model is:

[0007] A telescopic sludge removal clamp includes: an extension rod with an adjustable telescopic length, wherein the two ends of the extension rod are respectively provided with an operating mechanism and a clamping mechanism.

[0008] The operating mechanism includes: a winding wheel for winding a cable, a drive unit for driving the winding wheel to rotate, and a locking unit for locking the winding wheel.

[0010] When the cable is tightened, the extension slide bar is pulled, which drives the first and second clamps to close.

[0011] Furthermore, the drive unit includes: a main ratchet coaxially connected to the winding wheel, a secondary ratchet coaxially connected to the main ratchet, a secondary pawl engaged on the secondary ratchet for driving its unidirectional rotation, and an operating lever fixedly mounted on the mounting bracket of the secondary ratchet.

[0012] Furthermore, the locking unit includes: a main pawl that engages with the main ratchet to prevent it from rotating in the opposite direction, a pressure plate connected to the main pawl for controlling its disengagement from the main ratchet, and an unlocking trigger component that drives the pressure plate to move.

[0013] Furthermore, the unlocking trigger component includes: a rotating ear rotatably disposed on the operating mechanism, and a lever fixedly disposed on the rotating ear, wherein the lever can move the pressure plate when rotated;

[0014] And / or, it also includes: an extension handbrake movably sleeved on the extension rod, and a brake line connected between the extension handbrake and the pressure plate.

[0015] Furthermore, the main ratchet and the secondary ratchet are arranged in opposite directions of smooth rotation.

[0016] Furthermore, the clamping mechanism further includes: a first hinge plate and a second hinge plate respectively fixed outside the first clamping cover and the second clamping cover, the first hinge plate and the second hinge plate being hinged to each other, and a torsion spring being sleeved on the hinge axis of the first hinge plate and the second hinge plate, the torsion spring causing the first clamping cover and the second clamping cover to tend to remain separated.

[0017] Furthermore, the clamping mechanism further includes: a first cantilever and a second cantilever, one end of which is hinged to the same position at the lower end of the extension rod; the other end of the first cantilever is hinged to the first hinge plate; and the other end of the second cantilever is hinged to the second hinge plate.

[0020] Furthermore, the first and second clips are configured as hollow, open semi-cylindrical, hemispherical, or semi-ellipsoidal shapes.

[0021] The beneficial effects of this telescopic dredging clamp are as follows:

[0022] 1. With an adjustable telescopic extension rod, it is suitable for downhole dredging work at different depths;

[0023] 2. By winding the cable tightly with the winding wheel and pulling the clamping mechanism to clamp it, it saves time and effort when making mistakes;

[0047] a brake cable 25 is arranged on the vertical plate at the lower part of the pressure receiving plate 223.

[0048] The clamping mechanism 3, as shown in Figure 5 , comprises:

[0049] The first clamp 33 and the second clamp 36 are interlocked and openable. The first clamp 33 and the second clamp 36 are respectively hollow and open, in the shape of a semi-cylindrical, a hemispherical, and a semi-ellipsoidal shape, and have claws at their outer edges. A first hinge plate 32 is fixedly welded to the curved outer wall of the first clamp 33, and a second hinge plate 35 is fixedly welded to the curved outer wall of the second clamp 36. The first hinge plate 32 and the second hinge plate 35 are hinged to each other, and an extension is provided on the hinge axis of the first hinge plate 32 and the second hinge plate 35. The extension slide rod 30 and the torsion spring 37 are coaxially slidably connected at the lower end of the extension rod 1 and fixedly connected to the end of the cable 212.

[0050] An extension rod 1 is fitted with a slip ring, on which an extension handbrake 4 is mounted. The extension handbrake 4 is connected to the brake cable 25. The main ratchet 221 and the secondary ratchet 232 are arranged in opposite directions for smooth rotation.

[0051] Based on the specific structure of a telescopic dredging clamp in the above embodiments, its working process will be further explained below:

[0052] A. Adjust the length:

[0053] Rotate the rotating ear 241 to make the lever 242 move the pressure plate 223, causing the main pawl 222 to rotate and move away from the main ratchet 221; or, by extending the handbrake 4 and pulling the brake cable 25, the pressure plate 223 is pulled, causing the pawl 222 to rotate and move away from the main ratchet 221.

[0054] Adjust extension rod 1 to the appropriate length and lock it.

[0055] B. Cleaning:

[0056] Rotate the rotating ear 241 to move the lever 242 away from the pressure plate 223, and the main pawl 222 abuts against the main ratchet 221; under the action of the torsion spring 37, the first clamp 33 and the second clamp 36 are in a separated state that is far away from each other.

[0057] The operator holds the horizontal handle 202, inserts one end of the clamping mechanism 3 into the well, and rotates the operating lever 234. The secondary pawl 233 engages with the secondary ratchet 232, causing the secondary ratchet 232 to rotate, which in turn drives the main ratchet 221 and the winding wheel 211 to rotate coaxially. As the cable 212 winds around the winding wheel 211, it pulls the extension slide bar 30 and brings the lower ends of the extension rod 1 of the hinge axis of the first hinge plate 32 and the second hinge plate 35 closer together. Under the action of the first cantilever 31 and the second cantilever 34, the first clamp 33 and the second clamp 36 move closer to each other around the hinge axis of the first hinge plate 32 and the second hinge plate 35, and clamp the blockage in the well.

[0058] Under the abutting action of the main ratchet 221, the main ratchet 221 is locked, thereby keeping the cable 212 in a tightened state at this time, and the first clamp 33 and the second clamp 36 in a clamped state at this time.

[0059] The clamping mechanism 3, which is in a clamped state, is pulled out of the well along the extension rod 1; the brake line 25 is pulled by the extension handbrake 4, thereby pulling the pressure plate 223, causing the pawl 222 to rotate and move away from the main ratchet 221. Under the action of the torsion spring 37, the first clamp 33 and the second clamp 36 move away from each other, and the silt clamped between them is poured out.
