Description

[0001] This application is a divisional application of the patent application with the application number "202110697522.1", the application date of June 23, 2021, and the invention title of "Continuous Wall Construction Equipment". Technical Field

[0002] The present disclosure relates to the field of construction machinery, and particularly to a continuous wall construction equipment. Background Art

[0003] The working device of the continuous wall construction equipment includes a tool rest body, and a digging device, a mud pump, a deviation correction device, a lifting device, etc. installed on the tool rest body. Among them, the wire rope lifting device is located at the middle position of the upper part of the tool rest body and is connected to the tool rest body through a pin shaft.

[0004] When carrying out the grooving operation of the diaphragm wall, the working device digs downward along the height direction of the tool rest body, and finally forms a deep groove similar to a cuboid. The perpendicularity of the deep groove is crucial for the subsequent project construction. During the construction process, whether the tool rest body remains vertical is one of the key factors affecting the grooving perpendicularity.

[0005] However, due to the machining error of the tool rest body and the uneven weight distribution of the components installed on the tool rest body, the tool rest body is prone to deflection, which has an adverse effect on the digging direction of the digging device and the measurement reference of the inclination sensor arranged on the tool rest body, and finally will lead to the deflection of the direction of the deep groove.

[0046] Next, the technical solutions in the embodiments of the present disclosure will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present disclosure.

Therefore, other examples of the exemplary embodiments may have different values. It should be noted that like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0050] As Figures 1 to 5 shown, some embodiments of the present disclosure provide a diaphragm wall construction device, including a cutter head body 5, a lifting device 4, a suspension rod 1, and an adjusting device 3. In some embodiments, as Figure 1 shown, the diaphragm wall construction device may be a double-wheel milling machine. In some embodiments not shown, the diaphragm wall construction device may also be a hydraulic grab for diaphragm walls, etc.

[0051] The cutter head body 5 is used to connect the excavation cutters of the diaphragm wall construction device, such as the milling wheels 6 of a double-wheel milling machine.

[0052] The lifting device 4 is arranged above the cutter head body 5. The lifting device 4 is connected to the hoisting device of the diaphragm wall construction device through a steel wire rope. Under the drive of the hoisting device, the lifting device 4 can drive the cutter head body 5 to rise or fall.

[0053] The first end and the second end of the suspension rod 1 are respectively hinged to the lifting device 4 and the tool rest body 5.

[0054] The adjusting device 3 has an adjusting state and a locking state. In the adjusting state, the adjusting device 3 is configured to adjust the deflection angle of the suspension rod 1 relative to the tool rest body 5. In the locking state, the adjusting device 3 is configured to keep the relative positions of the suspension rod 1 and the tool rest body 5 unchanged.

[0055] Based on the diaphragm wall equipment provided by the embodiments of the present disclosure, the second end of the suspension rod is hinged to the tool rest body to form a rotating pair. During the diaphragm wall construction process, if the tool rest body deflects relative to the vertical direction, by switching the adjusting device to the adjusting state and adjusting the deflection angle of the tool rest body relative to the suspension rod, the attitude of the tool rest body can be corrected conveniently and safely. After adjusting the tool rest body to the vertical state, by switching the adjusting device to the locking state, the tool rest body can be kept in the above vertical state, which can alleviate the problem that the tool rest body deflects again due to the vibration during the construction process, thereby facilitating the improvement of the grooving perpendicularity of the diaphragm wall construction.

[0056] In some embodiments, as Figure 2 and Figure 3 shown, the adjusting device 3 includes a fixed ring 34, a movable member 33 and a feed adjusting mechanism. The fixed ring 34 is fixedly arranged relative to the suspension rod 1 and sleeved on the suspension rod 1. The movable member 33 is movably arranged relative to the tool rest body 5. The circumferential surface on the outer side of the fixed ring 34 and the circumferential surface on the inner side of the movable member 33 form a spherical kinematic pair. The feed adjusting mechanism includes a feed part and a locking part. In the adjusting state, the feed part is configured to drive the movable member 33 to move relative to the tool rest body 5 from at least one direction to change the relative position between the fixed ring 34 and the tool rest body 5. In the locking state, the locking part is configured to keep the relative position between the movable member 33 and the tool rest body 5.

[0057] According to the above settings of the fixed ring 34 and the movable member 33 of the adjusting device 3, the fixed ring 34 is fixedly arranged on the suspension rod 1. In the adjusting state, the feed part adjusts the relative position between the fixed ring 34 and the tool rest body 5 from at least one direction, so that the tool rest body 5 can deflect relative to the suspension rod 1 through the spherical kinematic pair formed between the fixed ring 34 and the movable member 33. The two mutually contacting spherical surfaces of the spherical kinematic pair are respectively the circumferential surface on the outer side of the fixed ring 34 and the circumferential surface on the inner side of the movable member 33. It is not necessary to machine spherical surfaces on the suspension rod 1 and the tool rest body 5, which is beneficial to reducing the processing difficulty of the suspension rod 1 and the tool rest body 5. The fixed ring 34 and the movable member 33 can both be fixed on the suspension rod 1 in the form of two half rings as Figure 3 shown, making the disassembly, assembly and replacement of the fixed ring 34 and the movable member 33 more convenient.

[0058] In some embodiments, as Figure 2 and Figure 3As shown in the figure, the feed adjustment mechanism includes a mounting base 31 and an adjustment bolt 32. The mounting base 31 is fixedly connected to the tool rest body 5. The mounting base 31 includes a base and at least one convex portion 311 provided on the base. A movable member 33 is provided on the base. The convex portion 311 has a first threaded hole 312. The adjustment bolt 32 is in mating connection with the first threaded hole 312. The tail end of the adjustment bolt 32 abuts against the movable member 33 and is used to adjust the relative position between the mounting base 31 and the movable member 33. The feed portion includes the first threaded hole 312 and the adjustment bolt 32.

[0059] According to the above settings of the feed adjustment mechanism, under the drive of the adjustment bolt 32, the relative movement between the movable member 33 and the mounting base 31 can be converted into the relative rotation between the movable member 33 and the fixed ring 34, realizing the relative deflection between the tool rest body 5 and the suspension rod 1. Multiple convex portions 311 can be provided on the mounting base 31 and multiple corresponding adjustment bolts 32 can be configured. The axes of at least two adjustment bolts 32 and at least two corresponding first threaded holes 312 are in different directions to adjust the relative position between the tool rest body 5 and the suspension rod 1 from different directions.

[0060] In some embodiments, as Figure 2 and Figure 3 shown, the feed adjustment mechanism further includes a nut 36. The nut 36 is in cooperation with the adjustment bolt 32 and is used to maintain the relative position between the adjustment bolt 32 and the convex portion 311. The locking portion includes the nut 36.

[0061] In some embodiments, as Figure 2 and Figure 3 shown, the mounting base 31 has a second threaded hole, and the movable member 33 has a mounting hole. The feed adjustment mechanism further includes a locking bolt 35. The dimension of the mounting hole in at least one direction is larger than the outer diameter of the locking bolt 35 so that the mating position of the locking bolt 35 in the mounting hole is adjustable. The locking bolt 35 passes through the movable member 33 and is in mating connection with the second threaded hole, and is used to fix the movable member 33 to the mounting base 31. The locking portion includes the locking bolt 35.

[0062] The locking effects of the nut 36 and the locking bolt 35 on the movable member 33 in different directions are conducive to better maintaining the relative position between the fixed ring 34 and the movable member 33, thereby being conducive to better maintaining the relative position between the suspension rod 1 and the tool rest body 5 and achieving a better locking effect.

[0063] In some embodiments, as Figure 4 shown, the diaphragm wall construction equipment further includes a hinge device 2. The suspension rod 1 and the tool rest body 5 are hinged through the hinge device 2. The hinge device 2 includes a hinge head 23 and a hinge seat. The hinge head 23 is fixedly connected to the suspension rod 1. The hinge seat is fixedly connected to the tool rest body 5 and forms a spherical kinematic pair with the hinge head.

[0064] In some embodiments, as Figure 4 shown, the hinge seat includes an upper hinge seat 22 and a lower hinge seat 25. The upper hinge seat 22 is disposed above the hinge head 23. The hinge head 23 includes a first spherical surface 231, and the hinge head 23 forms a spherical pair with the upper hinge seat 22 through the first spherical surface 231. The lower hinge seat 25 is disposed below the hinge head 23. The hinge head 23 includes a second spherical surface 232, and the hinge head 23 forms a spherical pair with the lower hinge seat 25 through the second spherical surface 232. The first spherical surface 231 and the second spherical surface 232 are concentric spherical surfaces.

[0065] According to the above settings of the upper hinge seat 22 and the lower hinge seat 25, the upper hinge seat 22 and the lower hinge seat 25 can respectively limit the upper end and the lower end of the hinge head 23, thereby restricting the up and down movement of the suspension rod 1 along its axial direction.

[0066] In some embodiments, as Figure 5 shown, the hinge device 2 further includes a cover plate 26 disposed at the top of the hinge seat. The cover plate 26 includes an inner ring 263 and an outer ring 261. The inner ring 263 is sleeved on the suspension rod 1 and is sealingly connected to the suspension rod 1 through the circumferential surface on the inner side. The outer ring 261 is disposed radially outside the inner ring 263. The outer ring 261 is fixedly connected to the hinge seat and is flexibly connected to the inner ring 263 so that the suspension rod 1 can deflect.

[0067] In some embodiments, as Figure 5 shown, as a specific form of the flexible connection between the outer ring 261 and the inner ring 263, the cover plate 26 further includes a flexible connection member 262. The inner ring 263 and the outer ring 261 are connected through the flexible connection member 262.

[0068] In some embodiments, as Figure 5 shown, on the basis of providing the flexible connection member 262, in order that the flexible connection member 262 can deform more flexibly when the suspension rod 1 deflects relative to the tool rest body 5, at least one axial end of the flexible connection member 262 has a groove provided along the circumferential direction.

[0069] In some embodiments, the hinge point between the suspension rod 1 and the tool rest body 5 is the center of gravity of the tool rest body 5, so that the adjustment process of the tool rest body is more convenient and labor-saving.

[0070] Next, in combination with Figures 1 to 5 the working principle of the diaphragm wall construction equipment according to some embodiments of the present disclosure and the adjustment of the attitude of the tool rest body of the diaphragm wall construction equipment will be further described. Figures 1 to 5 In the embodiments shown, for the components not specifically described, the functions of the components, and the positional relationships between the components, reference may be made to the relevant descriptions above.

[0071] As Figure 1As shown in the figure, the diaphragm wall construction equipment is a double-wheel milling machine, which includes a suspension rod 1, a hinge device 2, an adjusting device 3, a lifting device 4, a tool rest body 5 and a milling wheel 6. The hinge device 2 is fixedly connected to the inside of the tool rest body 5. The adjusting device 3 is located above the hinge device 2 and is fixedly connected to the upper part of the tool rest body 5. The first end of the suspension rod 1 is hinged to the lifting device 4 through a pin shaft, and the second end of the suspension rod 1 penetrates into the hinge device 2 and can deflect relative to the hinge device 2. The suspension rod 1 penetrates through the adjusting device 3. Under the action of the adjusting device 3, the tool rest body 5 can deflect relative to the suspension rod 1 to realize the attitude adjustment of the tool rest body 5.

[0072] As Figure 4 and Figure 5 shown in the figure, the hinge device 2 includes a support seat 21, an upper hinge seat 22, a hinge head 23, a lower hinge seat 25, a pin shaft 24 and a cover plate 26.

[0073] The support seat 21 has a hole-shaped structure with a limit protrusion inside, and its outside is fixedly connected to the tool rest body 5 through bolts. The hinge head 23 is provided with a central hole, and the suspension rod 1 penetrates into the central hole. The hinge head 23 and the suspension rod 1 are fixedly connected through the pin shaft 24.

[0074] The hinge head 23 includes a first spherical surface 231 provided at its top and a second spherical surface 232 provided at its bottom. The first spherical surface 231 and the second spherical surface 232 are concentric spherical surfaces.

[0075] The upper hinge seat 22 has a columnar structure and has a through hole inside. The bottom of the upper hinge seat 22 has a third spherical surface with the same radius as that of the first spherical surface 231.

[0076] The lower hinge seat 25 has a disc-shaped structure, and its edge is provided with bolt holes arranged circumferentially. The center of the top of the lower hinge seat 25 has a fourth spherical surface with the same radius as that of the second spherical surface 232. The first spherical surface and the third spherical surface, and the second spherical surface and the fourth spherical surface respectively form two spherical kinematic pairs. The lower hinge seat 25 is fixedly connected to the support seat 21 through bolts and presses the upper hinge seat 22 against the limit protrusion inside the support seat 21.

[0077] A receiving space is formed between the third spherical surface at the bottom of the upper hinge seat 22 and the fourth spherical surface at the top of the lower hinge seat 25. The hinge head can only rotate around the center of the first spherical surface 231 within this receiving space.

[0078] The cover plate 26 is installed on the top of the support base 21. The cover plate 26 includes an outer ring 261, a flexible connecting member 262, and an inner ring 263. The outer ring 261 and the inner ring 263 are made of metal, and the flexible connecting member 262 is made of rubber. The flexible connecting member 262 is fixedly connected to the outer ring 261 and the inner ring 263 through vulcanization process, bonding process or bolts. The outer ring 261 is provided with a plurality of connecting holes, and the cover plate 26 can be fixedly connected to the support base 21 through bolts. A through hole is provided in the middle of the inner ring 263, and the hanging rod 1 passes through the through hole. A seal is also provided between the inner ring 263 and the hanging rod 1. The upper end surface and the lower end surface of the flexible connecting member 262 respectively have a first groove 2621 and a second groove 2622 arranged along the circumferential direction of the flexible connecting member 262. When the hanging rod 1 deflects around the center of the first spherical surface 231, the flexible connecting member 262 can deform very flexibly.

[0079] As Figure 2 and Figure 3 shown, the adjusting device 3 includes a mounting seat 31, an adjusting bolt 32, a movable member 33, a fixing ring 34, a locking bolt 35, a nut 36, and a washer 37.

[0080] The mounting seat 31 is fixedly connected to the tool rest body 5. The mounting seat 31 is provided with a plurality of protruding portions 311, and the protruding portions 311 have first threaded holes 312. The axes of the first threaded holes 312 are arranged in the X direction or the Y direction as Figure 3 shown. The X direction and the Y direction can be the length direction and the width direction of the tool rest body 5 respectively. A plurality of second threaded holes that can cooperate with the locking bolts 35 are also provided on the base of the mounting seat 31, and the axis direction of the second threaded holes is perpendicular to the XY plane.

[0081] The movable member 33 has a plate-like structure. A spherical hole 331 is provided in the central area thereof, and the circumferential surface on the inner side of the movable member 33 is a spherical surface. A plurality of mounting holes located radially outside the spherical hole 331 are also provided on the movable member 33, and the dimension of the mounting holes in at least one direction is larger than the outer diameter of the locking bolt 35. The locking bolt 35 passes through the washer 37 and the mounting hole, and is screwed into the second threaded hole on the mounting seat 31. After the locking bolt 35 is tightened, the movable member 33 can be fixed to the mounting seat 31.

[0082] The adjusting bolt 32 sequentially passes through the first threaded hole 312 on the protruding portion 311 and the nut 36, and the tail end abuts against the outer side wall of the movable member 33. When the locking bolt 35 is loosened, the adjusting device 3 is in an adjusting state. When the adjusting bolt 32 moves relative to the protruding portion 311, the movable member 33 can be driven to slide on the mounting seat 31.

[0083] The circumferential surface inside the fixed ring 34 is a cylindrical surface, which can be composed of two half-rings and is locked on the suspension rod 1 by bolts, so that the relative position of the fixed ring 34 and the suspension rod 1 remains fixed. The circumferential surfaces on the outer sides of the fixed ring 34 and the movable member 33 are both spherical surfaces with equal radii, and a spherical pair is formed between the fixed ring 34 and the movable member 33.

[0084] The adjusting bolt 32 can drive the movable member 33 to move relative to the mounting seat 31, and further drive the fixed ring 34 to deflect relative to the movable member 33 around the center of the spherical hole 331, and further cause the tool rest body 5 to deflect relative to the suspension rod 1.

[0085] The working principle of this diaphragm wall construction equipment is as follows:

[0086] The steel wire rope driven by the hoisting device bypasses the lifting device 4 to suspend the tool rest body 5 off the ground, and the tool rest body 5 hangs freely. When the tool rest body 5 deviates from the vertical state and needs to be adjusted, loosen the locking bolts 35 and nuts 36 on the adjusting device 3, and the adjusting device 3 is in the adjusting state.

[0087] If the height direction of the tool rest body 5 (i.e., Figure 1 the up and down direction) is not perpendicular to the X-axis direction, adjust the two adjusting bolts 32 whose axes are arranged along the X-axis direction, and drive the movable member 33 to move along the X-axis direction, and further drive the suspension rod 1 to deflect around the centers of the first spherical surface 231 and the second spherical surface 232 until the height direction of the tool rest body 5 is perpendicular to the X-axis direction.

[0088] If the height direction of the tool rest body 5 is not perpendicular to the Y-axis direction, adjust the four adjusting bolts 32 whose axes are arranged along the Y-axis direction, and drive the movable member 33 to move along the Y-axis direction, and further drive the suspension rod 1 to deflect around the centers of the first spherical surface 231 and the second spherical surface 232 until the height direction of the tool rest body 5 is perpendicular to the Y-axis direction.

[0089] If the height direction of the tool rest body 5 is perpendicular to both the X-axis direction and the Y-axis direction, tighten the locking bolts 35 and nuts 36 on the adjusting device 3 to lock the movable member 33, the adjusting device 3 is in the locking state, and the relative position of the suspension rod 1 and the tool rest body 5 remains fixed.

[0090] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present disclosure and are not intended to limit them; although the present disclosure has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that: it is still possible to modify the specific implementation manners of the present disclosure or perform equivalent replacements for some technical features, and they should all be covered within the scope of the technical solutions claimed by the present disclosure.
