Description

Technical Field

[0001] The present invention relates to the field of cutting box lifting of a TRD method machine, and in particular to a cutting box lifting auxiliary device and a lifting method suitable for a TRD method machine. Background Art

[0002] The TRD construction machine is a construction method that can form a continuous wall of equal thickness underground. The TRD construction machine includes a main machine, a cutting box and a lifting cylinder. The main machine is located above the cutting box, and the main machine and the cutting box are connected by bolts. The lifting cylinder is used to lift the main machine and the cutting box. The cutting box is composed of a number of cutting box monomers connected in sequence from top to bottom, and two adjacent cutting box monomers are connected by bolts. When the TRD construction machine is working, the cutting box is underground. Due to geological collapse, improper construction operation and other reasons, the cutting box is very easy to be adsorbed, clamped, and stuck by the underground wall, resulting in the TRD construction machine's own lifting cylinder being unable to reach the ability to pull out the trapped cutting box. The method usually adopted is to disconnect the main machine of the TRD construction machine from the cutting box and use special pile pulling equipment to pull out the cutting box. These methods take a particularly long time to prepare. Often, due to excessive delays in time, the drilling of the cutting box is more serious, resulting in the failure of the "salvage" of the cutting box, causing huge economic losses to the project and equipment.

[0061] A plurality of reinforcing plates are arranged on the outer sides of the front and rear side plates of the auxiliary lifting box.

[0062] Auxiliary lifting box The upper and lower end surfaces of the auxiliary lifting box are both provided with mud discharge holes 1.7. Specifically, the mud discharge holes are arranged on the upper and lower end plates of the auxiliary lifting box.

[0063] Further, such as Figure 1 , Figure 2 As shown, box ear plates 1.8 are provided on the opposite side surfaces of the auxiliary lifting box 1. Specifically, box ear plates are provided on the front and rear side plates of the auxiliary lifting box. Two upper and lower mounting holes (i.e., upper mounting hole 1.9 and lower mounting hole 1.10) are provided on the box ear plate. One side of the support 2 is provided with a support ear plate 2.1 that cooperates with the box ear plate on one side of the auxiliary lifting box.

The connecting member 4 is two connecting pins 4.1, one of which passes through the upper mounting hole of the support ear plate and the upper mounting hole of the box ear plate, and the other connecting pin passes through the lower mounting hole of the support ear plate and the lower mounting hole of the box ear plate. In this way, the installation and disassembly of the support and the auxiliary lifting box are convenient.

[0064] Further, such as Figure 1 , Figure 2 As shown, the upper end of the piston rod of the jacking oil cylinder 3 is provided with a cylinder ear plate 3.1 that matches the jacking ear, and the cylinder ear plate and the jacking ear are connected through the ear plate pin 5. In this way, the installation and disassembly of the piston rod and the support of the jacking oil cylinder are convenient.

[0065] Specific embodiment 2, as Figure 3 As shown, a method for pulling out a cutting box using a cutting box pulling out auxiliary device applicable to a TRD method machine is provided. The specific structure of the cutting box pulling out auxiliary device applicable to a TRD method machine is referred to in the first specific embodiment. The method for pulling out a cutting box using a cutting box pulling out auxiliary device applicable to a TRD method machine comprises the following steps in sequence:

[0066] First, separate the main machine of the TRD method machine from the cutting box, and then the lifting cylinder of the TRD method machine drives the main machine to move upward.

[0067] Second, place the auxiliary lifting box 1 on the top surface of the cutting box 7, and connect the auxiliary lifting box and the cutting box with bolts; then, the lifting cylinder of the TRD method machine drives the main machine to move down and rest against the top surface of the auxiliary lifting box, and then, connect the auxiliary lifting box and the main machine of the TRD method machine with bolts. The lifting cylinder and the jacking cylinder of the TRD method machine are located on opposite sides of the cutting box.

[0068] Third, a support base 6 is laid on the ground surface below the support, and the jacking cylinder 3 is located above the support base, and the lower end of the jacking cylinder is supported on the upper surface of the support base.

[0069] Fourth, use the lifting cylinder and jacking cylinder of the TRD construction machine to pull out the cutting box. The specific steps are as follows: the lifting cylinder and jacking cylinder of the TRD construction machine work at the same time. The lifting cylinder of the TRD construction machine pulls up the cutting box, and the jacking cylinder pulls up the cutting box through the support and the auxiliary lifting box. In this way, the jacking cylinder can cooperate with the lifting cylinder of the TRD construction machine itself to pull out the cutting box, thereby increasing the lifting force on the cutting box and improving the lifting and untrapping ability of the TRD construction machine's cutting box. On the other hand, the buried cutting box can be trapped in a shorter time and the cutting box can be "salvaged".

[0070] Specific embodiment 3 is a method for pulling out a cutting box using a cutting box pulling out auxiliary device suitable for a TRD method machine. The specific steps of the pulling out method refer to the specific embodiment 2, except that the fourth embodiment further includes the following steps:

[0071] Fifth, separate the main unit of the TRD machine from the cutting box and move the TRD machine away;

[0072] Remove the support from the auxiliary lifting box;

[0073] Next, the cutting box is lifted by a crane, and the crane is connected to the box ear plates on the auxiliary lifting box through a lifting rope; then, the cutting box is lifted by the crane through the lifting rope and the auxiliary lifting box.

[0074] Specific embodiment four, as Figure 4 As shown, a method for pulling out a cutting box using a cutting box pulling out auxiliary device applicable to a TRD method machine is provided. The specific structure of the cutting box pulling out auxiliary device applicable to a TRD method machine is referred to in the first specific embodiment. The method for pulling out a cutting box using a cutting box pulling out auxiliary device applicable to a TRD method machine comprises the following steps in sequence:

[0075] First, separate the main unit of the TRD method machine from the cutting box and move the TRD method machine away.

[0076] Second, place the auxiliary lifting box 1 on the top surface of the cutting box 7, and connect the auxiliary lifting box and the cutting box with bolts.

[0077] A support base 6 is laid on the ground surface below the support, and the jacking cylinder 3 is located above the support base, and the lower end of the jacking cylinder is supported on the upper surface of the support base.

[0078] Third, the cutting box is lifted by a crane and a lifting cylinder. The crane is connected to the lifting lug of the support through a lifting rope 8. The crane lifts the cutting box upwards through the lifting rope, the support and the auxiliary lifting box. At the same time, the lifting cylinder lifts the support and lifts the cutting box upwards through the support and the auxiliary lifting box. In this way, the lifting cylinder can cooperate with the crane to lift the cutting box, thereby increasing the lifting force on the cutting box and improving the lifting and untrapping ability of the cutting box of the TRD construction machine. On the other hand, the buried cutting box can be trapped in a shorter time and the cutting box can be "salvaged" out.

[0079] Specific embodiment 5 is a method for pulling out a cutting box using a cutting box pulling out auxiliary device applicable to a TRD method machine. The specific structure of the cutting box pulling out auxiliary device applicable to a TRD method machine is referred to in specific embodiment 1. The method for pulling out a cutting box using a cutting box pulling out auxiliary device applicable to a TRD method machine comprises the following steps in sequence:

[0080] First, separate the main unit of the TRD method machine from the cutting box and move the TRD method machine away.

[0081] Second, if Figure 5 , Figure 6 As shown, a wire rope laying device is used to lay a wire rope underground. The wire rope laying device includes a wire rope 9.1, a limit steel pipe 9.3 and two guide steel pipes 9.2. The lower end of the limit steel pipe is provided with a wire rope limit groove with an opening facing the lower end. The wire rope passes through the two guide steel pipes in sequence. Both ends of the wire rope are provided with lifting rings. The specific steps of laying a wire rope underground using the wire rope laying device include:

[0082] (1) The limiting steel pipe and two guide steel pipes are erected and distributed vertically. The two guide steel pipes are distributed on the front and rear sides of the cutting box, and the limiting steel pipe is distributed on the left or right side of the cutting box. The wire rope passes through the wire rope limiting groove. In this embodiment, there are also two limiting steel pipes, one of which is close to the front side of the cutting box, and the other is close to the rear side of the cutting box.

[0083] (2) Insert the two guide steel pipes and the limit steel pipe downward into the soil layer until the lower ends of the two guide steel pipes and the lower ends of the limit steel pipes are both located at a set distance below the cutting box of the TRD method machine; during this process, the wire rope always passes through the two guide steel pipes, the wire rope passes through the wire rope limit groove, and both ends of the wire rope are located above the ground surface;

[0084] Next, pull up the two ends of the steel wire rope above the ground until the entire steel wire rope is in a straightened state; then pull up the limiting steel pipe to separate the steel wire rope from the steel wire rope limiting groove;

[0085] Next, continue to pull up both ends of the steel wire rope above the ground until the entire steel wire rope is in a straight state. At this time, the steel wire rope between the lower ends of the two guide steel pipes will be located below the cutting box of the TRD construction machine.

[0086] In this embodiment, the guide steel pipe and the limit steel pipe are distributed in the underground cement soil continuous wall formed by the TRD construction method machine construction, and the construction steps of laying the steel wire rope underground using the steel wire rope laying device are all completed before the underground cement soil continuous wall is solidified. Since the underground cement soil continuous wall is formed by mixing cement soil, the underground cement soil continuous wall is relatively soft before solidification, and the guide steel pipe, the limit steel pipe and the steel wire rope can be laid in place.

[0087] Third, place the auxiliary lifting box 1 on the top surface of the cutting box 7, and connect the auxiliary lifting box and the cutting box with bolts;

[0088] A support base 8 is laid on the ground surface below the support, a jacking cylinder is located above the support base, and the lower end of the jacking cylinder is supported on the upper surface of the support base;

[0089] Fourth, two cranes and a lifting cylinder are used to lift the cutting box. The specific steps include: the lifting rings at both ends of the wire rope are hung on the hook of one of the cranes, and the other crane is connected to the lifting lug of the support through the lifting rope; the two cranes and the lifting cylinder work simultaneously, one of the cranes lifts the lower end of the cutting box upwards through the wire rope, and the other crane lifts the cutting box upwards through the lifting rope, the support and the auxiliary lifting box; the lifting cylinder lifts the support, and lifts the cutting box upwards through the support and the auxiliary lifting box.

[0090] When drilling the cutting box, the clamping force of the drill may be too large, exceeding the maximum tensile force that the bolts connecting two adjacent cutting box units can withstand. During the process of pulling out the cutting box, the bolts connecting two cutting box units may break (the pulling force of the cutting box exceeds the maximum tensile force that the bolts connecting two adjacent cutting box units can withstand), resulting in partial or major part of the cutting box being buried, causing huge economic losses to the project and equipment. The pulling out method of this embodiment is to solve this problem. Specifically,

[0091] Because in the second step of the lifting method of this embodiment, a wire rope laying device is used to lay the wire rope underground, and the wire rope is passed around the bottom of the cutting box. In this way, when one of the cranes lifts the lower end of the cutting box upwards through the wire rope, the bolts on the cutting box for connecting two adjacent cutting box units are not subjected to force. Therefore, the lifting force of the crane on the cutting box through the wire rope will not damage the bolts for connecting the two adjacent cutting box units. In this way, the cutting box can be lifted and pulled out by cooperating with another crane and a lifting cylinder. The lifting and pulling force on the cutting box can be greatly improved without damaging the bolts on the cutting box for connecting the two adjacent cutting box units, thereby greatly improving the lifting and pulling out ability of the cutting box of the TRD construction machine, and "salvaging" the cutting box.

[0092] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any way. Any simple modification, change and equivalent transformation made to the above embodiment based on the technical essence of the present invention still falls within the protection scope of the technical solution of the present invention.
