Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pulling-out equipment of stratum cutting device, and particularly relates to a TRD cutting box buried drill pulling-out device. BACKGROUND

[0002] The TRD cutting box is a device which inserts a cutting box with a chain and a cutter head into the ground to a designed depth, cuts the soil vertically, and then pushes forward to cut a groove horizontally, while injecting cement slurry into the foundation to mix with the original soil, so as to form a thick wall with uniform quality and continuity.

[0003] A cutting box for super-deep TRD method is disclosed in Chinese Utility Model Patent No. 2018200360617, which is connected with several cutting boxes and a power box to achieve the effect of cutting deep underground.

[0004] During the downward excavation or upward lifting of the cutting box, the cutting box is tightly wrapped and stuck by the stratum (usually soft soil, quicksand, gravel layer or complex stratum) due to various reasons, and cannot be pulled out by relying on the lifting force of the equipment itself, so the pulling-out equipment is needed to pull out the cutting box.

[0005] Chinese Utility Model Patent No. 2021220422336 discloses a TRD cutting box buried drill pulling-out device, which drives the working box to move upward by the piston rod of the hydraulic cylinder, and clamps the cutting box by the clamping block connected to the working box to pull out the cutting box.

[0006] However, the existing TRD cutting box is fixed layer by layer, and the overall height of the cutting box is high. When the existing pulling-out equipment pulls out the high cutting box, the hydraulic cylinder needs to be set high, and the stability of the hydraulic cylinder is poor. When the cutting box is pulled out as a whole, it is inconvenient to supplement the quick-setting paste-like slurry to the bottom layer of the cutting box as the pulling-out height of the cutting box increases, so that the sand soil continuously flows into the cutting box during the overall lifting of the cutting box, causing a vicious cycle of "the more you pull, the more you bury". SUMMARY

[0007] The present application provides a TRD cutting box buried drill pulling-out device, which has the advantages of high stability of the hydraulic cylinder for pulling out and convenient pulling out of multiple layers of cutting boxes, to solve the problem of poor stability of the hydraulic cylinder and the vicious cycle of "the more you pull, the more you bury" when pulling out the overall cutting box spliced by several cutting boxes.

[0008] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: a TRD cutting box buried drill pulling-out device, characterized in that it comprises two groups of supporting wheels arranged on both sides of the cutting box, two supporting wheels in the same group are arranged vertically, and a lifting chain is arranged between the two supporting wheels in the same group.

[0009] The two single chains on the two sides of the lifting chain are respectively connected with a first connecting chain and a second connecting chain, and the first connecting chain and the second connecting chain are respectively arranged in an upper-lower opposite manner on the two single chains on the two sides of the lifting chain.

[0010] Further, the first connecting chain and the second connecting chain are respectively connected with a separable lifting chain assembly through the shackle at one end of the lifting chain, and one single chain on one side of the lifting chain is fixedly connected with the top end of the piston rod of the pulling hydraulic cylinder.

[0011] In use, the pulling hydraulic cylinder drives the piston rod to drive one single chain on one side of the lifting chain to move up and down, so that the lifting chain assembly connected with one end of the first connecting chain and the second connecting chain alternately pulls the cutting box to move up as a whole for pulling, and the cutting box to be pulled is grouted through the grouting hole during pulling, and the first cutting box pulled out of the ground is disassembled and transferred by the crane through the lifting chain assembly during alternate pulling.

[0012] Further, the two groups of supporting wheels are respectively rotationally connected to the two supporting columns, the supporting columns support and fix the supporting wheels, and the supporting wheels can rotate on the supporting columns, facilitating the transmission of the lifting chain under the lifting action of the piston rod of the pulling hydraulic cylinder. The two supporting columns and the pulling hydraulic cylinder are fixedly installed on the top of the base, the base can be fixed on the moving platform or the vehicle body, so that the base can be moved to the cutting box when the TRD cutting box is buried, and the pulling hydraulic cylinder is located outside the supporting column.

[0013] Further, the diameters of the lifting chain, the first connecting chain, the second connecting chain and the pulling lifting chain are not less than 40 mm, so as to ensure that the breaking tension is large enough to prevent the chain from breaking during pulling of the cutting box.

[0014] Further, the two single chains on the two sides of the lifting chain are respectively fixedly installed with a first clamping sleeve and a second clamping sleeve, the first clamping sleeve and the second clamping sleeve are the same in structure, one end of the first clamping sleeve is connected with the first connecting chain, and one end of the second clamping sleeve is connected with the second connecting chain, the first clamping sleeve and the second clamping sleeve are fixed to the lifting chain, so that one end of the first connecting chain and one end of the second connecting chain are respectively connected to the first clamping sleeve and the second clamping sleeve, and the first clamping sleeve and the second clamping sleeve move up and down during transmission of the lifting chain, so as to drive the first connecting chain and the second connecting chain to move up, respectively.

[0015] Further, the two sides of the first clamping sleeve and the second clamping sleeve are respectively provided with a through groove, the first connecting chain is hung to the through groove of the first clamping sleeve through the shackle at one end of the first connecting chain, the second connecting chain is hung to the through groove of the second clamping sleeve through the shackle at one end of the second connecting chain, and the first connecting chain and the second connecting chain are respectively hung to the second clamping sleeve through the shackles at one end of the first connecting chain and one end of the second connecting chain, facilitating installation and disassembly.

[0016] Further, the two through grooves of the first and second clamping sleeves are designed to be perpendicular to the connecting line of the two through grooves, so that the two first connecting chains can be arranged in staggered positions with the second connecting chain and the single chain on one side of the lifting chain, to ensure that the first connecting chain is not blocked and interfered by the single chain on one side of the lifting chain and the second connecting chain when the first connecting chain pulls the cutting box to be lifted and moved upward.

[0017] Further, the lifting chain assembly comprises a connecting ring, the hook rings at one end of the first and second connecting chains are connected with the connecting ring, and two lifting lifting chains are further connected to the connecting ring, and the two lifting lifting chains are connected with the connecting ring through the hook rings at one end, and the hook rings at the other end of the lifting lifting chains are used to be connected with the starting slot holes on one side of the top of the cutting box, after the uppermost cutting box is lifted, the connecting ring is separated from the first and second connecting chains through the connecting ring, the hook of the crane is connected with the connecting ring, and the cutting box which is pulled out of the ground and removed can be directly lifted and transported by the crane, so that when the subsequent cutting box is pulled out, the uppermost cutting box is used to inject the rapid-setting paste slurry, the quicksand passage at the bottom of the cutting box is blocked, and the situation that the sand soil continuously flows into the cutting box when the cutting box is lifted as a whole is prevented, so that the vicious cycle of "the more the cutting box is pulled out, the more it is buried" is avoided.

[0018] Further, the first and second clamping sleeves are both formed by splicing two half clamping sleeves and are fixed by bolts, so that the first and second clamping sleeves can be conveniently fixed and installed on the lifting chain and move up and down with the transmission of the lifting chain, and the upper and lower sides of the first clamping sleeve are respectively provided with positioning clamping blocks which are fixed on one single chain of the lifting chain, and the positioning clamping blocks are formed by splicing two half clamping blocks and are fixed by bolts, so that the positioning clamping blocks can be conveniently fixed on the lifting chain.

[0019] The application has the following beneficial effects:

[0020] 1. The TRD cutting box buried drilling lifting device provided by the application is provided with lifting chains on both sides of the cutting box, the lifting chains are driven to move up and down by the piston rod of the lifting hydraulic cylinder, the single chains on both sides of the lifting chain are connected with the cutting box through chains, the cutting box after buried drilling is alternately lifted, and the uppermost cutting box is removed and transferred each time, the cutting box is pulled out layer by layer, the length of the lifting hydraulic cylinder for lifting is only required to be controlled to be not less than the height of a single cutting box, compared with the mode of directly arranging an ultra-long hydraulic cylinder to lift the cutting box as a whole, the short stroke of the lifting hydraulic cylinder has high stability.

[0021] 2. The cutting box is pulled out layer by layer, so that after a cutting box pulled out of the ground is removed each time, the overall weight of the cutting box to be pulled out is reduced, and the subsequent cutting box is more easily removed.

[0022] 3. By alternately pulling out the cutting boxes after burying the drill, and disassembling and transferring the uppermost cutting box each time it is pulled out, the cutting boxes are pulled out layer by layer, which facilitates the replenishment of the quick-setting paste slurry into the hole through the cutting box, blocks the quicksand channel at the bottom of the cutting box, prevents the quicksand layer at the bottom of the cutting box from continuously pouring in during the overall lifting of the cutting box, and prevents the vicious cycle of "the more you pull, the more you bury".

[0035] Please continue to refer to Figures 1-4 The upper and lower sides of the first clamping sleeve 5 are respectively provided with a positioning clamping block 7 fixedly sleeved on a single chain of the lifting chain 4, as Figure 7 indicated, the positioning clamping block 7 is spliced by two half clamping blocks and fixed by bolts, so as to be fixed and disassembled, a pulling hydraulic cylinder 8 is fixedly installed on the top of the base 1 and located outside the support column 2, the top end of the piston rod of the pulling hydraulic cylinder 8 is fixedly connected with the two positioning clamping blocks 7, when the piston rod of the pulling hydraulic cylinder 8 moves upwards, the two positioning clamping blocks 7 and the first clamping sleeve 5 move upwards, the lifting chain 4 moves clockwise between the two support wheels 3, as Figure 4 indicated, and at the same time, the second clamping sleeve 6 on the other single chain moves downwards, when the piston rod of the pulling hydraulic cylinder 8 moves downwards, the positioning clamping block 7 and the first clamping sleeve 5 move downwards, the lifting chain 4 moves counterclockwise between the two support wheels 3, and at the same time, the second clamping sleeve 6 on the other single chain moves upwards.

[0036] Please refer to Figures 4-6 , the two center lines of the through grooves of the first and second clamping sleeves 5 and 6 are designed to be perpendicular, a first connecting chain 9 is sleeved in each of the two through grooves of the first clamping sleeve 5, and the first connecting chain 9 is hung to the through groove of the first clamping sleeve 5 through the shackle at one end of the first connecting chain 9, a second connecting chain 10 is sleeved in the through groove of the second clamping sleeve 6, and the second connecting chain 10 is also hung to the through groove of the second clamping sleeve 6 through the shackle at one end of the second connecting chain 10, and the first and second connecting chains 9 and 10 are convenient to install and disassemble through the shackles.

[0037] The other end of each of the first and second connecting chains 9 and 10 is also provided with a shackle, and a connecting ring 11 is connected to the shackle, and two lifting chains 12 are connected to the connecting ring 11, and the two lifting chains 12 are connected to the connecting ring 11 through the shackles at one end, and the shackles at the other end of the lifting chains 12 are used to be connected to the starting through holes on one side of the top of the cutting box, if the cutting box is not provided with through holes, a clamping jaw can be additionally provided to clamp one side of the cutting box, and the clamping jaw is connected to the shackles at the other end of the lifting chains 12, and the clamping jaw is a known clamping device, which will not be described here.

[0038] In use, first, the piston rod of the lifting hydraulic cylinder 8 drives the positioning clamping block 7 and the first clamping sleeve 5 to move close to the support wheel 3 above the support column 2, at this time, the second clamping sleeve 6 is close to the support wheel 3 below the support column 2, then the shackle at one end of the second connecting chain 10 is hung on the connecting ring 11 (which can be operated by the construction personnel standing on the scaffold), at the same time, the shackles at one end of the two lifting chains 12 are hung on the connecting ring 11, and the shackles at the other end of the two lifting chains 12 are hung on the through grooves on one side of the cutting box, after the lifting chains 12, the connecting ring 11 and the second connecting chain 10 on both sides of the cutting box are connected, the lifting hydraulic cylinder 8 drives the piston rod to drive the positioning clamping block 7 and the first clamping sleeve 5 to move downward, at this time, the second clamping sleeve 6 on the other side of the lifting chain 4 pulls the second connecting chain 10, the connecting ring 11 and the lifting chains 12 to move upward, thereby pulling the cutting box to move upward, and during the pulling of the cutting box to move upward, the quick-setting paste-like slurry (such as water glass + bentonite) is injected into the hole through the grouting hole of the first cutting box to block the flow sand channel at the bottom of the cutting box, so as to prevent the sand in the flow sand layer at the bottom of the cutting box from continuously flowing into the cutting box during the lifting of the cutting box, thereby forming a vicious cycle of "the more the lifting, the more the burying".

[0039] When the positioning clamp 7 moves to the support wheel 3 near the support column 2, the second cutting box moves to the support wheel 3 near the support column 2. The hook at one end of the second connecting chain 10 is hooked onto the connecting ring 11. At the same time, the hooks at one end of the two lifting chains 12 are hooked onto the connecting ring 11, and the hooks at the other ends of the two lifting chains 12 are hooked onto the through slots on one side of the second cutting box. After the lifting chains 12, connecting rings 11 and the second connecting chain 10 on both sides of the second cutting box are connected, the second connecting chain 10 is separated from the connecting ring 11. The connecting ring 11 connected to the first cutting line is placed on the hook of the crane (this crane is an existing device used to transfer the cutting box when the cutting line is installed layer by layer, not shown in the figure, and will not be described here). Then the bolts and nuts used to fix the two cutting boxes are removed, and the first cutting box is transferred by the crane.

[0040] Finally, the lifting hydraulic cylinder 8 is activated to drive the piston rod to move the positioning clamp 7 upward. This causes the positioning clamp 7 to move the first clamp 5, the first connecting chain 9 connecting ring 11, and the lifting and hoisting chain 12 upward, thereby pulling the second cutting box upward. Quick-setting paste-like grout is injected into the hole through the grouting hole on the second cutting box until the positioning clamp 7 moves to the support wheel 3 near the top of the support column 2. At this time, the third cutting box moves to the support wheel 3 near the bottom of the support column 2. The above steps are repeated. One end of the lifting and hoisting chain 12 connected to the second connecting chain 10 is hooked to the slot on one side of the third cutting box, and the second cutting box is disassembled and transferred. This process is repeated to pull out, remove, and transfer the cutting boxes in sequence.
