Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a pad displacement device for a TRD method machine. Background Technology

[0002] The TRD (Trans-Ram Slab Drilling) method is a complete set of equipment and construction methods for continuous wall construction in various soil and gravel layers. The TRD method involves inserting a cutting tool equipped with a cutting chain and cutting head, reaching the designed depth, into the ground. While longitudinally cutting and laterally advancing to form a trench, cement grout is injected into the foundation to achieve thorough mixing with the undisturbed soil, forming a continuous wall of uniform thickness underground. Unlike traditional single-axis or multi-axis auger drilling methods that create column-type cement-soil underground continuous walls, the TRD method first inserts a chainsaw-type cutting tool into the foundation, excavating to the designed wall depth. Then, a curing agent is injected to mix with the in-situ soil, and lateral excavation and mixing are continued, advancing horizontally to construct a high-quality cement-soil mixed continuous wall. The main characteristics of this construction method are continuous wall formation, smooth surface, uniform thickness, and good wall homogeneity. It is mainly used in various building projects, underground engineering, revetment projects, dam and embankment foundation reinforcement, and seepage prevention.

[0003] To ensure the flatness of the wall, shims are typically laid along the operating path of the TRD (Tracking Method) machine, creating a smooth working path on the construction site. Because the shims are heavy, a limited number can be used. After each section of the path is completed, the shims need to be moved to the next section. Currently, cranes or excavators are mainly used on construction sites to move the shims, which is time-consuming and cumbersome. There is an urgent need to design a moving device to improve the efficiency of shim relocation. Utility Model Content

[0004] Therefore, the main technical problem to be solved by this utility model is how to improve the displacement efficiency of the TRD process pad.

[0005] To achieve the above objectives, the technical solution of this utility model embodiment is implemented as follows:

[0006] A pad shifting device for a TRD (Tracking Method) machine includes a vehicle body and a self-locking mechanism mounted on the vehicle body. The vehicle body includes a support frame, wheels, and a top plate. The side of the support frame is triangular, the wheels are located at the bottom of the support frame, and the top plate is inclinedly mounted on the top of the support frame. The self-locking mechanism includes a housing, a clamping arm, a locking tongue, and a spring. The housing is located at the higher end of the support frame and forms a latch with the top plate. The middle position of the locking tongue is rotatably connected to the end of the clamping arm. The first end of the locking tongue is connected to the housing via the spring, and the second end of the locking tongue is arc-shaped. Under the action of the spring, the second end of the locking tongue abuts against the top plate.

[0007] Preferably, the vehicle body further includes multiple roller assemblies, and multiple clearance holes are provided on the top plate. The roller assemblies are installed on the side of the top plate near the traveling wheels, and the wheel body of the roller assembly protrudes from the side of the top plate away from the traveling wheels through the clearance holes.

[0008] Preferably, the roller assembly includes a rotating shaft, fasteners, and a wheel body, the rotating shaft passing through the wheel body, and both ends of the rotating shaft being fixed to the top plate near the side of the traveling wheel by the fasteners.

[0009] Preferably, the plurality of roller assemblies are arranged in two columns, and the two columns of roller assemblies are symmetrically arranged along the centerline position of the width direction of the top plate.

[0010] Preferably, the self-locking mechanism includes an operating handle, and the housing is provided with a clearance groove. One end of the operating handle is connected to the first end of the locking tongue, and the other end of the operating handle protrudes from the housing through the clearance groove.

[0011] Preferably, the second end of the locking tongue is provided with anti-slip teeth.

[0012] Preferably, the vehicle body further includes a handle, one end of which is provided with a grip bar, and the other end of which is rotatably connected to the bracket.

[0013] Preferably, the top plate forms an angle of 20-40 degrees with the horizontal ground.

[0014] Preferably, the system further includes an auxiliary limiting assembly disposed on the bracket. The auxiliary limiting assembly includes a spring shaft, a limiting arm, and two limiting posts. One end of the limiting arm is rotatably disposed on the side of the bracket. The rotation axis of the limiting arm is perpendicular to the length direction of the limiting arm. The main body of the spring shaft is embedded in the bracket, and the elastic extension end of the spring shaft protrudes from the side of the bracket. The two limiting posts are respectively located on both sides of the spring shaft.

[0015] In the above-described technical solution of this application, the pad shifting device includes a vehicle body and a self-locking mechanism mounted on the vehicle body. The side of the vehicle body support is triangular, with one end higher than the other. Therefore, when transporting the pad, only the pad needs to be slightly lifted to allow the vehicle body to be scooped under the pad. By pushing the vehicle body, the pad slides down the top plate onto the vehicle body, which is convenient and labor-saving. Once the entire pad is placed on the vehicle body, the self-locking mechanism locks the pad, allowing workers to transport it to a specific location. After reaching the designated location, releasing the locking tongue of the self-locking mechanism allows the pad to slide down the top plate under gravity, placing the top plate in the predetermined position. This device allows for convenient and labor-saving loading, transporting, and unloading of pads without the need for an excavator, greatly improving work efficiency. Attached Figure Description

[0027] Please refer to the attached document. Figure 1 To be continued Figure 5 One embodiment of this application provides a pad shifting device for a TRD (Tracking Method) machine, including a vehicle body 100 and a self-locking mechanism 200 disposed on the vehicle body 100. The vehicle body 100 is used to place and move the pad, and the self-locking mechanism 200 is used to lock the pad onto the vehicle body 100.

[0028] The vehicle body 100 includes a support frame 110, wheels 120, and a top plate 130. The support frame 110 has a triangular shape, with one end higher than the other. The wheels 120 are located at the bottom of the support frame 110 to facilitate the movement of the vehicle body 100. The top plate 130 is inclined at the top of the support frame 110, with the lower end of the top plate 130 close to the ground. Therefore, when moving a pad, only the pad needs to be slightly lifted to scoop the vehicle body 100 under the pad. By pushing the vehicle body 100, the pad slides along the top plate 130 onto the vehicle body 100, completing the installation of the pad, which is convenient and time-saving.

[0029] The self-locking mechanism 200 includes a housing 210, a clamping arm 220, a locking tongue 230, and a spring 240. The housing 210 is located at the higher end of the bracket 110 and forms a bayonet 250 with the top plate 130, allowing the pad to enter the bayonet 250. The middle position of the locking tongue 230 is rotatably connected to the end of the clamping arm 220. The first end of the locking tongue 230 is connected to the housing 210 via the spring 240, and the second end of the locking tongue 230 is arc-shaped. Under the action of the spring 240, the second end of the locking tongue 230 abuts against the top plate 130. When the pad slides onto the top plate 130 and enters the bayonet 250, the locking tongue 230 abuts against the pad, forming a self-locking mechanism that prevents the pad from sliding down the slope. Therefore, once the entire pad is placed on the top plate 130, the self-locking mechanism 200 locks the pad, allowing the worker to transport the pad to a specific location. Once transported to the designated location, the locking tongue 230 is loosened, allowing the pad to slide down the top plate 130 under gravity, placing the top plate 130 in the predetermined position. The device of this application allows for convenient and labor-saving loading, transportation, and unloading of the pad without the need for an excavator, greatly improving operational efficiency.

[0030] In the above-described technical solution of this application, the pad shifting device includes a vehicle body 100 and a self-locking mechanism 200 mounted on the vehicle body 100. The side of the support 110 of the vehicle body 100 is triangular, with one end higher than the other. Therefore, when moving the pad, only the pad needs to be slightly lifted to allow the vehicle body 100 to be scooped under the pad. By pushing the vehicle body 100, the pad slides down the top plate 130 onto the vehicle body 100, which is convenient and labor-saving. Once the entire pad is placed on the vehicle body 100, the self-locking mechanism 200 locks the pad, allowing workers to transport the pad to a specific location. After reaching the specific location, releasing the locking tongue 230 of the self-locking mechanism 200 allows the pad to slide down the top plate 130 under gravity, placing the top plate 130 in the predetermined position. With this device, the loading, transportation, and unloading of pads can be completed conveniently and labor-savingly, without the need for an excavator, greatly improving work efficiency.

[0031] In a preferred embodiment of this application, the vehicle body 100 may further include multiple roller assemblies 140, and the top plate 130 has multiple clearance holes 131. The roller assemblies 140 are installed corresponding to the positions of the clearance holes 131. Specifically, the roller assemblies 140 are installed on the side of the top plate 130 near the traveling wheels 120, and the wheel bodies 143 of the roller assemblies 140 protrude from the side of the top plate 130 away from the traveling wheels 120 through the clearance holes 131. Multiple roller assemblies 140 can effectively reduce the friction on the top plate 130, making the insertion of the pad smoother. After lifting the pad, the vehicle body 100 is scooped under the pad and pushed, allowing the pad to slide smoothly onto the vehicle body 100 along the top plate 130. Further details can be found in the appendix. Figure 3The roller assembly 140 includes a rotating shaft 141, a fastener 142, and a wheel body 143. The rotating shaft 141 passes through the wheel body 143, and both ends of the rotating shaft 141 are fixed to the top plate 130 near the traveling wheel 120 by the fasteners 142. The wheel body 143 protrudes outward from the top plate 130 away from the traveling wheel 120 through the clearance hole 131, reducing friction while ensuring the aesthetics of the outer side of the top plate 130.

[0032] In the appendix Figure 2 In the illustrated embodiment, the multiple roller assemblies 140 can be arranged in two rows, with the two rows of roller assemblies 140 symmetrically arranged along the centerline of the width direction of the top plate 130. The two rows of roller assemblies 140 precisely meet the support and sliding requirements of the pad, allowing the pad to slide smoothly on the top plate 130. The number of self-locking mechanisms 200 can also be two, with the two self-locking mechanisms 200 symmetrically arranged along the centerline of the width direction of the top plate 130.

[0033] As an optional embodiment of this application, the self-locking mechanism 200 may further include an operating handle 260. A clearance groove 270 is provided on the housing 210. One end of the operating handle 260 is connected to the first end of the latch 230, and the other end of the operating handle 260 protrudes from the housing 210 through the clearance groove 270. The operating handle 260 is used by a worker to push it to loosen the latch 230 and release the pad. Rotating the latch 230 by the operating handle 260 can separate the latch 230 from the pad, unloading the pad.

[0034] As an optional embodiment of this application, the second end of the locking tongue 230 may be provided with anti-slip teeth 231, thereby increasing the coefficient of friction between the locking tongue 230 and the pad, and preventing accidental loosening during transportation. The top plate 130 forms an angle of 20-40 degrees with the horizontal ground; this angle allows the pad to slide down smoothly and also makes it easier to install. Preferably, the vehicle body 100 may also include a handle 150, one end of which is provided with a grip bar 151 for easy handling, and the other end of which is rotatably connected to the bracket 110. Workers pull the vehicle body 100 using the handle 150 to transport the pad to a specific location. The handle 150 is installed at the centerline of the bracket 110 in the width direction.

[0035] As an optional embodiment of this application, to avoid temporary failure of the self-locking mechanism due to sudden vibrations caused by uneven road surfaces during transportation, the pad shifting device further includes an auxiliary limiting component 300 disposed on the bracket 110. The auxiliary limiting component 300 is used to further prevent the pad from slipping. Please refer to the appendix. Figure 6 and attached Figure 7The auxiliary limiting assembly includes a spring shaft 310, a limiting arm 320, and two limiting posts 330. One end of the limiting arm 320 is rotatably mounted on the side of the bracket 110, and the axis of rotation of the limiting arm 320 is perpendicular to its length. The spring shaft 310 is a shaft capable of elastic extension and retraction, also known as an elastic roller, and includes a main body and an elastic extension and retraction end that is elastically mounted within the main body using a spring. The main body of the spring shaft 310 is embedded within the bracket 110, and the elastic extension and retraction end of the spring shaft 310 protrudes from the side of the bracket 110. The two limiting posts 330 are located on both sides of the spring shaft 310. When not loaded, the auxiliary limiting assembly 300 of the pad shifting device operates as follows: Figure 6 As shown in the diagram. When the pad is loaded, press the spring shaft 310 to release the obstruction of the limiting arm 320, and move the limiting arm 320 to the end of the stop pad, as shown. Figure 7 As shown. During unloading, pressing the spring shaft 310 again will cause the limit arm 320 to fall down again. Figure 6 The state shown is as follows. The two limit posts 330 are used to limit the maximum range of motion of the limit arm 320, so as to prevent the limit arm 320 from falling to the ground and colliding and rubbing against the ground.

[0036] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. The protection scope of this utility model should be determined by the protection scope of the stated claims.
