Description

Technical Field

[0001] The utility model relates to the field of groundwater precipitation related equipment, in particular to a clamp used for pulling out underground water pipes. Background Art

[0002] After the groundwater in the foundation pit is dewatered, the underground water pipes perpendicular to the ground need to be pulled out from the foundation pit. Previously, ropes were directly put on the underground water pipes, and then the underground water pipes were pulled out by crane. Due to the force of the ropes, the underground water pipes were unevenly stressed, so the underground water pipes were prone to damage and breakage, affecting the next use and reducing the service life of the underground water pipes. In addition, when the water pipes were pulled out, due to the uneven force, there was an inclination between the underground water pipes and the soil, which further deepened the friction between the underground water pipes and the soil, reduced the speed of pulling out the underground water pipes, and delayed the progress of the project.

[0003] In document CN201921444445, a special fixture for a sleeve pulling test machine is disclosed, comprising a lower fixed seat and an upper fixed seat, the lower fixed seat and the upper fixed seat are matched with each other, one side of the lower fixed seat is fixedly connected with a hinge seat by bolts, the hinge seat is provided with a jack, the hinge seat is connected with a hinge block by a rotating shaft, the hinge block and the upper fixed seat are fixedly connected by bolts, a lower embedding groove is provided above the lower fixed seat, an upper embedding groove is provided below the upper fixed seat, an annular groove is provided on the inner sides of the lower embedding groove and the upper embedding groove, a limiting groove is provided on one side of the annular groove in the lower embedding groove and the upper embedding groove, one side of the lower fixed seat is fixedly connected with a locking mechanism by bolts, the special fixture for the sleeve pulling test machine is designed according to the sleeve structure to fix and limit the sleeve. When this structure is in use, it needs to be locked by another locking mechanism. In addition, the force on the tube is uneven. If this structure is used for plugging and unplugging, it is easy to cause the tube to break.

[0004] Therefore, a new technical solution is needed to solve the above technical problems. Summary of the invention

[0005] In order to solve the above problems, the utility model discloses a clamp for pulling out underground water pipes. The pipe can be clamped by lifting the fixed ear with a lifting rope, and no additional clamping mechanism is required. When the vertical underground water pipe is pulled out or inserted, the underground water pipe can be prevented from being worn, and the efficiency of pulling out the underground water pipe can be improved, thereby speeding up the overall work efficiency.

[0006] The technical solution of the utility model is: a clamp for pulling out underground water pipes, comprising a sleeve and a fixing ear, the sleeve comprising a half pipe a and a half pipe b, the fixing ear being fixed on the sleeve, an adaptive reinforcement column being arranged in the sleeve, the fixing ears being respectively arranged on the outside of the half pipe a and the half pipe b, a connecting plate being further arranged on the half pipe b, and the connecting plate and the half pipe a being movably connected.

[0007] By adopting the above technical solution, the sleeve of the clamp is put on the outer periphery of the underground water pipe. Since the bottoms of half pipe a and half pipe b are movably connected, when the crane lifts it upward through the lifting rope, the lower half of the sleeve is subjected to force through the connecting plate as a supporting point, and the upper half of half pipe a and half pipe b are subjected to force to clamp the underground water pipe, and then the vertical underground water pipe is lifted upward by the crane through the lifting rope on the fixed ear.

[0008] Preferably, the diameter of the sleeve is matched to the diameter of the underground water pipe, and it is just fitted onto the outside of the underground water pipe. The fixing ears on the outside of the half-pipe a and the half-pipe b are symmetrically distributed with the center line of the sleeve as the axis of symmetry, and through holes are also provided near the top of the half-pipe a and the half-pipe b.

[0009] By adopting the above technical solution, the sleeve is just sleeved on the periphery of the underground water pipe, and the fixing ears at both ends can be symmetrically arranged, so that the force on both sides is even when the crane is hoisting. When the underground water pipe is hoisted, the underground water pipe is prevented from being unevenly stressed, causing the underground water pipe to tilt, and the friction between the underground water pipe and the soil is increased, so that the underground water pipe is lifted vertically upwards, the underground water pipe is prevented from being damaged, and the speed of lifting the underground water pipe can be accelerated.

[0010] Preferably, a lifting rope is provided in the through holes of half pipe a and half pipe b. The lifting rope is a rope or a chain. The lifting rope is in a downward Y shape. The forked end of the Y shape is connected to the through holes of half pipe a and half pipe b. The two sides of the lifting rope are symmetrical, and the other end of the Y shape is lifted by a crane.

[0011] By adopting the above technical solution, when the crane lifts half pipe a and half pipe b through the lifting rope, the symmetry on both sides of the lifting rope can facilitate the lifting of the underground water pipe vertically upward, prevent the underground water pipe from tilting, increase sudden and direct friction, affect the speed of pulling up the underground water pipe, and protect the underground water pipe.

[0012] Preferably, the fixing ear is upward as a whole, an acute angle is formed between the lower side of the fixing ear and the bottom of the sleeve, an obtuse angle is formed upward between the inside of the fixing ear outside the sleeve, and the fixing ear and the half tube a and the half tube b are integrally formed.

[0013] By adopting the above technical solution, the fixing ears are lifted upward by the lifting ropes, and the obtuse angle between the fixing ears can make the fixing ears have enough angle to play a role of pressing between the half pipe a and the half pipe b, thereby playing a role of clamping and tightening the underground water pipe.

[0014] Preferably, the connecting plate is located on the outer side of the half-tube b close to the bottom, and connecting plates are provided on both sides of the half-tube a. One end of the connecting plate is welded to the outer surface of the half-tube b, and the other end is located on the outside of the half-tube a.

[0015] By adopting the above technical solution, the connecting plate connects the half pipe a and the half pipe b at the same time, so that a sleeve is formed between the half pipe a and the half pipe b and is sleeved on the underground water pipe.

[0016] Preferably, the portion of the half pipe a located inside the connecting plate is provided with a through hole, the portion of the connecting plate located outside the half pipe a is movably connected to the through hole via bolts, and the portion of the bolt located inside the half pipe a is provided with a nut.

[0017] By adopting the above technical solution, half pipe a is connected to half pipe b through bolts and nuts, and a movable connection is formed between half pipe a and half pipe b. When the fixed ear is lifted upward by the lifting rope, half pipe a rotates around the bolt on the connecting plate, and then the upper part of half pipe a and the upper part of half pipe b are in close contact, which plays a role of tightly clamping the underground water pipe.

[0018] Preferably, when the reinforcement column is in use, the reinforcement column is a solid cylindrical shape that matches the underground water pipe and is tightly plugged into the underground water pipe. The length of the reinforcement column is greater than the height of the casing.

[0019] By adopting the above technical solution, the reinforcement column is inserted into the underground water pipe. When the casing clamps it, the clamping force of the casing is very large, and the presence of the reinforcement column can protect the underground water pipe and prevent damage to the water pipe.

[0020] Preferably, the position where the sleeve is clamped on the underground water pipe is in the middle of the position where the reinforcement column is inserted.

[0021] By adopting the above technical solution, the sleeve clamps the middle part of the reinforcing column insertion position, and the clamping force of the sleeve can be transferred from the underground water pipe to the reinforcing column to prevent damage to the underground water pipe.

[0022] Advantages of the utility model: 1. The utility model can improve the strength of the underground water pipe by inserting the reinforcing column into the underground water pipe. When the clamp is clamped therein, due to the presence of the reinforcing column, the clamp is clamped on the water pipe corresponding to the reinforcing column, which can prevent the water pipe from rupture and damage.

[0023] 2. The utility model provides a connecting plate at the bottom of the clamp, so that when the suspension rope pulls the fixing ear upward, the half pipe a rotates slightly around the bolt, and the half pipe a and the half pipe b are tightly combined with the bolt as the support point to clamp the underground water pipe.

[0024] 3. The utility model sets the half pipe a, the half pipe b and the fixing ears in a symmetrical shape, so that when the lifting rope lifts it, the underground water pipe always keeps a uniform force state, and when it is pulled out from the ground, no tilting force is generated, the friction between the pipe and the soil is reduced, and the pulling speed is increased.

[0025] 4. The fixing ears on both sides of the casing of the utility model are connected to the lifting rope. When the crane is lifted upward, the two sides of the fixing ears are acted upon by the lifting rope upward, which just makes the half pipe a and half pipe b connected thereto be tightened inward, thereby clamping the underground water pipe.

[0026] 5. The utility model can prevent the underground water pipe from being worn when the vertical underground water pipe is pulled out and inserted, and can improve the efficiency of pulling out the underground water pipe, thereby speeding up the overall work efficiency.

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0034] like Figure 1-5As shown, the clamp for pulling out the underground water pipe includes a sleeve and a fixing ear 6. The sleeve includes a half pipe a1 and a half pipe b3. The fixing ear 6 is fixed on the sleeve. An adaptive reinforcement column 8 is provided in the sleeve. The fixing ears 6 are respectively located on the outside of the half pipe a1 and the half pipe b3. A connecting plate 4 is also provided on the half pipe b3. The connecting plate 4 and the half pipe a1 are movably connected. The sleeve of the clamp is sleeved on the periphery of the underground water pipe. Since the bottom of the half pipe a1 and the half pipe b3 are movably connected, when the crane is lifted upward by the lifting rope 9, since the lower half of the sleeve is subjected to force through the connecting plate 4 as a supporting point, the upper half of the half pipe a1 and the half pipe b3 are subjected to force to clamp the underground water pipe, and then the vertical underground water pipe is lifted upward by the crane through the lifting rope 9 on the fixing ear 6.

[0035] The diameter of the sleeve is matched with the diameter of the underground water pipe, and it is just sleeved on the outside of the underground water pipe. The fixing ears 6 on the outside of the half pipe a1 and the half pipe b3 are symmetrically distributed with the center line of the sleeve as the symmetry axis. The half pipe a1 and the half pipe b3 are also provided with a through hole 7 near the top. The sleeve is just sleeved on the periphery of the underground water pipe. The fixing ears 6 at both ends can be symmetrically arranged. When the crane is hoisting, the force on both sides is uniform. When the underground water pipe is hoisted, uneven force on the underground water pipe is prevented, causing the underground water pipe to tilt, increasing the friction between the underground water pipe and the soil, so that the underground water pipe is lifted vertically upward, preventing the underground water pipe from being damaged, and speeding up the lifting of the underground water pipe.

[0036] A lifting rope 9 is provided in the through holes of the half pipe a1 and the half pipe b3. The lifting rope 9 is a rope or a chain. The lifting rope 9 is in a downward Y-shape. The forked end of the Y-shape is connected to the through holes 7 of the half pipe a1 and the half pipe b3. The lifting rope 9 is symmetrical on both sides. The other end of the Y-shape is lifted by a crane. When the crane lifts the half pipe a1 and the half pipe b3 through the lifting rope, the symmetry of the lifting rope 9 on both sides can facilitate the lifting of the underground water pipe vertically upward, prevent the underground water pipe from tilting, increase the sudden direct friction, affect the speed at which the underground water pipe is pulled up, and protect the underground water pipe.

[0037] The fixing ear 6 is upward as a whole, and there is an acute angle between the lower side of the fixing ear 6 and the bottom of the sleeve, and an obtuse angle upwards between the fixing ear 6 outside the sleeve. The fixing ear 6 and the half pipe a1 and the half pipe b3 are integrally formed, and the fixing ear 6 is lifted upward by the lifting rope 9. The obtuse angle between the fixing ears 6 can make the fixing ears 6 have enough angle to fit the half pipe a1 and the half pipe b3 tightly, thereby clamping and tightening the underground water pipe.

[0038] The connecting plate 4 is located on the outer side of the half-pipe b3 close to the bottom. Connecting plates 4 are provided on both sides of the half-pipe a1. One end of the connecting plate 4 is welded to the outer surface of the half-pipe b3, and the other end is located on the outer side of the half-pipe a1. The connecting plate 4 connects the half-pipe a1 and the half-pipe b3 at the same time, so that a sleeve is formed between the half-pipe a1 and the half-pipe b3, which is sleeved on the underground water pipe.

[0039] The portion of the half pipe a1 located on the inner side of the connecting plate 4 is provided with a through hole 7, the portion of the connecting plate 4 located on the outer side of the half pipe a1 is movably connected with the through hole 7 via a bolt 5, the portion of the bolt 5 located on the inner side of the half pipe a1 is provided with a nut, the half pipe a1 is connected to the half pipe b3 via the bolt 5 nut, and a movable connection is formed between the half pipe a1 and the half pipe b3, when the fixing ear 6 is lifted upward by the lifting rope 9, the half pipe a1 rotates on the connecting plate 4 around the bolt 5, and then the upper part of the half pipe a1 and the upper part of the half pipe b3 are in close contact, so as to tightly clamp the underground water pipe.

[0040] A rope is provided on the top of the reinforcement column 8 for easy taking. When the reinforcement column 8 is in use, the reinforcement column 8 is a solid cylindrical shape that matches the underground water pipe and is tightly plugged into the underground water pipe. The length of the reinforcement column 8 is greater than the height of the casing. The reinforcement column 8 is inserted into the underground water pipe. When the casing clamps it, the clamping force of the casing is very large, and the presence of the reinforcement column 8 can protect the underground water pipe and prevent damage to the water pipe.

[0041] The position where the sleeve is clamped on the underground water pipe is the middle of the position where the reinforcement column 8 is inserted. The sleeve clamps the middle of the insertion position of the reinforcement column 8. The clamping force of the sleeve can be transferred from the underground water pipe to the reinforcement column 8 to prevent damage to the underground water pipe.

[0042] When pulling out a vertical underground water pipe, the sleeve is placed on the water pipe, and then the bolt 5 is tightened on the half pipe a1, and then the lifting rope 9 is lifted by the crane, so that the half pipe a1 and the half pipe b3 can tightly clamp the water pipe and pull out the underground water pipe.

The functions and structural principles of the present invention have been demonstrated and explained in the embodiments, and the implementation methods of the present invention may be deformed or modified in any way without departing from the principles.
