Description

Technical Field

[0001] This utility model relates to the field of TRD cutting technology, specifically to a TRD cutting box lifting auxiliary device. Background Technology

[0002] The TRD cutting box is a core component of the equal-thickness cement-soil underground continuous wall construction method. Its function is to excavate, mix, and inject solidification fluid into the foundation soil using chainsaw-like cutters to form a high-strength cement-soil continuous wall of equal thickness. The cutting box contains chainsaw-like cutters consisting of a chain and a cutter head. A hydraulic motor drives the chain to rotate cyclically, causing the cutter head to cut longitudinally and advance laterally into the soil. The cutting box is first driven vertically into the ground to the designed depth, then advanced horizontally while excavation fluid or solidification fluid is injected, forcibly mixing with the in-situ soil to form the cement-soil continuous wall.

[0003] A lifting auxiliary device is needed during the use of TRD cutting boxes. Utility model patent CN216075305U discloses a TRD cutting box drilling lifting device, including a base plate. Several lifting lugs are symmetrically fixed to the upper surface of the base plate, and several hydraulic cylinders are symmetrically fixed to the upper surface of the base plate. A fixing plate is fixed to the extended end of each hydraulic cylinder, and a working box is fixed to the bottom surface of the fixing plate. Grooves are symmetrically opened on the side wall of the working box. A motor is fixed inside the working box, and a drive gear is fixed to the extended end of the motor. A threaded rod is rotatably connected between the side wall of the working box and the grooves. A driven gear that meshes with the drive gear is coaxially connected to the threaded rod. Sliding blocks that can slide within the grooves are threaded to both ends of the threaded rod. This utility model solves the problem that existing lifting devices are unstable when the cutting box is pulled out, easily causing it to fall off.

[0004] However, during the pulling process of the TRD cutting box, each section of the TRD cutting box needs to be removed before the pulling can continue. During the pause, the TRD cutting box underground is prone to sliding down, making subsequent pulling difficult. Therefore, a TRD cutting box pulling auxiliary device is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a TRD cutting box lifting auxiliary device, which has the advantages of preventing the TRD cutting box from sliding down before it is lifted out. It solves the problem that in common lifting devices, the TRD cutting box on the ground is prone to sliding down during the pause process, which makes subsequent lifting difficult.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A TRD cutting box lifting auxiliary device includes a mounting base plate, four lifting cylinders are fixedly mounted on the top of the mounting base plate, a lifting top plate is fixedly mounted on the movable end of the lifting cylinders, and an anti-fall component is provided on the top of the mounting base plate.

[0008] The fall protection assembly includes two fall protection uprights fixedly installed on the top of the mounting base plate. Two fall protection cylinders are fixedly installed on the opposite side of each of the two fall protection uprights. Fall protection clamping plates are fixedly installed on the movable end of each fall protection cylinder, and the fall protection clamping plates are located between the two fall protection uprights.

[0009] Furthermore, the top of the mounting base plate is provided with a lifting positioning hole, which is compatible with the TRD cutting box.

[0010] Furthermore, the top of the lifting plate is provided with a top through hole, which is adapted to the TRD cutting box and aligned with the lifting positioning hole.

[0011] Furthermore, two lifting plates are fixedly installed at the bottom of the lifting top plate, and two clamping cylinders are fixedly installed on the side of each of the two lifting plates that are far apart from each other.

[0012] Furthermore, a lifting clamping plate is fixedly installed on the movable end of the clamping cylinder, and the lifting clamping plate is located between the two lifting upright plates.

[0013] Furthermore, mounting cylinders are fixedly installed at the top four corners of the mounting base plate, and support cylinders are fixedly installed at the top of the mounting cylinders.

[0014] Furthermore, the movable end of the support cylinder extends into the interior of the mounting cylinder, and a support base plate is fixedly installed on the movable end of the support cylinder.

[0015] Furthermore, the bottom of the support base plate is rotatably mounted with movable wheels via wheel frames, and through holes with the same inner diameter as the mounting cylinder are opened at the four corners of the top of the mounting base plate. The maximum size of the movable wheels is smaller than the inner diameter of the mounting cylinder.

[0016] Compared with the prior art, this utility model provides a TRD cutting box lifting auxiliary device, which has the following beneficial effects:

[0017] 1. This TRD cutting box lifting auxiliary device, by setting an anti-fall component on the top of the mounting base plate, uses an anti-fall cylinder to drive two anti-fall clamping plates to move inward during the lifting process, clamping the second TRD cutting box that has been pulled out of the ground. This prevents the TRD cutting box underground from sliding down when the top layer of TRD cutting boxes is being disassembled, thus solving the problem that in common lifting devices, the underground TRD cutting box is prone to sliding down during the pause, leading to difficulties in subsequent lifting.

[0018] 2. The TRD cutting box lifting auxiliary device is equipped with mounting cylinders at the top four corners of the mounting base plate, support cylinders at the top of the mounting cylinders, and movable wheels on the support base plate at the bottom of the movable end of the support cylinders. When movement is required, the movable wheels are moved downward by the support cylinders so that the movable wheels contact the ground, making it convenient to move the mounting base plate.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 4 The TRD cutting box lifting auxiliary device in this embodiment includes a mounting base plate 1. Four lifting cylinders 2 are fixedly installed on the top of the mounting base plate 1. A lifting top plate 3 is fixedly installed on the movable end of the lifting cylinder 2. An anti-fall component is provided on the top of the mounting base plate 1.

[0026] The anti-fall component includes two anti-fall uprights 4 fixedly installed on the top of the mounting base plate 1. Two anti-fall cylinders 5 are fixedly installed on the opposite sides of the two anti-fall uprights 4. Anti-fall clamping plates 6 are fixedly installed on the movable ends of the anti-fall cylinders 5, and the anti-fall clamping plates 6 are located between the two anti-fall uprights 4.

[0027] Specifically, the anti-fall cylinder 5 is activated, which drives the two anti-fall clamping plates 6 to clamp the second TRD cutting box, preventing the TRD cutting box from sliding down the ground.

[0028] Meanwhile, the top of the mounting base plate 1 is provided with a lifting positioning hole 7, which is compatible with the TRD cutting box.

[0029] The top of the lifting plate 3 is provided with a top through hole 8, which is adapted to the TRD cutting box and is aligned with the lifting positioning hole 7.

[0030] Meanwhile, two lifting plates 9 are fixedly installed at the bottom of the lifting top plate 3, and two clamping cylinders 10 are fixedly installed on the side of the two lifting plates 9 that are far apart from each other.

[0031] The clamping cylinder 10 has a lifting clamping plate 11 fixedly installed on its movable end, which is located between the two lifting upright plates 9. The clamping cylinder 10 drives the two lifting clamping plates 11 to clamp the uppermost TRD cutting box, and the lifting cylinder 2 drives the lifting top plate 3 to rise, lifting the TRD cutting box out of the ground.

[0032] Meanwhile, mounting cylinders 12 are fixedly installed at the top four corners of the mounting base plate 1, and support cylinders 13 are fixedly installed on the top of the mounting cylinders 12.

The maximum size of the movable wheel 15 is smaller than the inner diameter of the mounting cylinder 12. When the support cylinder 13 extends, it pushes the movable wheel 15 downwards, making it contact the ground, facilitating the movement of the mounting base plate 1. After the mounting base plate 1 is moved to a suitable position, the support cylinder 13 retracts, the movable wheel 15 returns to the mounting cylinder 12, and the mounting base plate 1 is placed on the ground.

[0035] The working principle of the above embodiment is as follows: the clamping cylinder 10 drives the two lifting clamping plates 11 to clamp the uppermost TRD cutting box, the lifting cylinder 2 drives the lifting top plate 3 to rise, and lifts the TRD cutting box out of the ground. The anti-fall cylinder 5 is activated, which drives the two anti-fall clamping plates 6 to clamp the second TRD cutting box to prevent the TRD cutting box from sliding down the ground.

[0036] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented.
