Description

Technical Field

[0001] This invention belongs to the field of tunnel lining technology, specifically relating to a vibratory compaction structure and a lining trolley containing the vibratory compaction structure. Background Technology

[0002] In some mixture-based molding processes, such as concrete pouring, plastic injection molding, and sand casting, it is often necessary to stir or vibrate the mixture to remove air bubbles or to make the molded structure denser. Traditional methods involve stirring the mixture with tools or using a vibrator, but in actual production, there are often unsuitable operating conditions, leading to poor final molding results. Taking tunnel secondary lining as an example, during secondary lining construction, workers place a vibrator on the poured concrete to vibrate it. However, the effect of the vibrator gradually weakens from the center point outwards, failing to achieve deep and wide-area vibration.

[0003] Traditional vibration methods include immersion vibration or mixing with tools. However, these conditions are not always met in many situations. Furthermore, immersion vibration weakens outwards from the vibrating tool, resulting in a small vibration range. Another traditional method is attached vibrator. However, the traditional approach involves installing the attached vibrator inside the working panel of the trolley, which is connected to the trolley frame. The vibrator transmits the excitation force to the material through the vibrating panel, but the excitation force is transmitted to the trolley frame along with the panel, thus weakening the vibration force on the material and resulting in insufficient vibration. In other words, attached vibrators are directly connected to the main structure, which weakens their vibration force. Summary of the Invention

[0004] The present invention provides a double-layer panel structure and a lining trolley containing the same, comprising a shaped panel, a vibrating panel, and a vibrating assembly. The first side of the shaped panel is connected to the main support structure, and the second side of the shaped panel is partially connected to the first side of the vibrating panel so that the vibrating panel fits the shaped panel and has a vibration space. The second side of the vibrating panel is in contact with the vibrating material, and the vibrating assembly passes through the shaped panel and is connected to the vibrating panel.

[0005] Optionally, the vibrating panel and the shaping panel are connected by a circumferential rigid connection, while the remaining parts are connected by a contact connection.

[0006] Optionally, spaced plug welding holes and / or notches are provided around the vibratory panel, and the shaped panel and the vibratory panel are fixed together by spot welding to the plug welding holes and / or notches.

[0007] Optionally, a separator may be provided between the vibratory panel and the shaping panel.

[0008] Optionally, the isolation element may be configured as an elastic element or other structural element with elastic properties.

[0009] Optionally, the thickness of the vibratory panel may be thinner than that of the shaping panel.

[0010] Optionally, a release agent may also be applied to the end face of the vibratory panel that comes into contact with the material being vibrated.

[0011] Optionally, the vibrating assembly is configured as an attached vibrator or an immersion vibrator;

[0012] Alternatively, the vibratory assembly may be configured as a combination of an attached vibrator and an insert vibrator.

[0013] The present invention also provides a lining trolley, including a template assembly and a trolley frame;

[0014] The template assembly is installed on the trolley frame to form a secondary lining outline. The template assembly includes a template frame and a vibratory structure as described above.

[0015] The shaping panel is disposed on the template frame, and the vibrating panel is connected to the side of the shaping panel away from the template frame.

[0016] Optionally, the template assembly is configured to include a top mold and a side mold that are hinged to each other, and both the top mold and the side mold are provided with a template frame and a vibration structure as described above;

[0017] Alternatively, the template assembly may be configured to include a top mold and a side mold that are hinged to each other. The top mold is provided with a template frame and a vibration structure as described above. The side mold is provided with a single-layer panel and a vibration assembly that are connected to each other. The end face of the single-layer panel away from the vibration assembly is in contact with the vibrating material, and the excitation force is transmitted to the vibrating material through the single-layer panel.

[0018] Alternatively, the template assembly may be configured to include a top mold and a side mold that are hinged to each other. The top mold may have a single-layer panel and a vibrating assembly that are connected to each other. The end face of the single-layer panel away from the vibrating assembly is in contact with the vibrating material, and the excitation force is transmitted to the vibrating material through the single-layer panel. The side mold may have a template frame and a vibrating structure as described above.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) In this invention, the vibrating working surface is set as a double-panel structure, and the vibration is ensured that all positions of the working surface except the rigid connection point can be vibrated during vibration. The excitation force reaches the maximum value at the middle where the vibrating element is installed, so as to realize the vibration of the entire vibrating working surface, thereby giving it the characteristics of greater vibration effect, wider vibration range, and better mixture molding effect.

[0021] (2) The double-layer panel vibratory lining trolley provided by the present invention sets the vibratory working surface in the template assembly as a double-layer panel structure including a shaping panel and a vibratory panel, and installs the vibratory element on the shaping panel but not in contact with the vibratory panel, so that the excitation force is directly transmitted to the vibrating material through the shaping panel, thereby maximizing the excitation force of the vibratory element on the vibrating material. This solves the problem that when the trolley vibrates the template panel, the excitation force of the vibrator is transmitted through the template to the entire trolley because the template and the trolley frame are connected, which weakens the excitation force of the template on the vibrating material, resulting in a loose structure of the vibrating material and problems such as voids and honeycomb pitting.

[0022] (3) By completely placing the shaping panel inside the vibrating panel, the present invention ensures that there is no gap between the contact surface of the vibrating working surface (i.e. the shaping panel) and the vibrating material, and avoids misalignment, thus ensuring the shaping effect of the vibrating material.

[0023] (4) In this invention, plug welding holes and notches are provided at corresponding positions around the shaping panel and the vibrating panel for welding and fixing, while maintaining a close fit in the middle. This ensures that the template panels will not be misaligned due to the double-layer panels, and also ensures that the vibrating panel has maximum freedom, so that the vibrator can achieve the best effect of vibrating the material through the vibrating panel when vibrating.

[0024] (5) In this invention, the vibrating working surfaces in the top mold and side molds, which are hinged to each other in the template assembly, are both set as double-layer panel structures; or, the vibrating working surface on the top mold is a double-layer panel while the vibrating working surface on the side mold is a single-layer panel structure; or, the vibrating working surface on the top mold is a single-layer panel while the vibrating working surface on the side mold is a double-layer panel structure. By using double-layer panel templates and mixed single and double-layer panel templates, not only can double-layer panels be used for large-area vibration of key areas, but also single-layer panels can be used for concentrated vibration of localized areas using insertable vibrators. This point-to-surface vibration method improves the quality of the vibrated material.

[0025] (6) By setting the vibrating element as an attached vibrator or an inserted vibrator; or a combination of an attached vibrator and an inserted vibrator, the present invention can save some of the cost of the inserted vibrating element (the inserted vibrator is a point vibration, while this solution is a surface vibration), and can also use a lower cost vibrating element (only needs to vibrate the working surface, and under the same requirements, the requirements for the vibrating element are lower); and the number of operators can also be reduced, and each vibrating element can be controlled by electrical control.

[0026] In addition to the objectives, features, and advantages described above, the present invention has other objectives, features, and advantages. The invention will now be described in further detail with reference to the figures. Attached Figure Description

It should be noted that the accompanying drawings of the present invention are all in a simplified form and use non-precise proportions, and are only used to facilitate and clearly assist in illustrating the implementation of the present invention; the "several" mentioned in the present invention are not limited to the specific number shown in the examples in the accompanying drawings; the orientations or positional relationships indicated by terms such as "front," "middle," "rear," "left," "right," "up," "down," "top," "bottom," and "center" mentioned in the present invention are all based on the orientations or positional relationships shown in the accompanying drawings of the present invention, and do not indicate or imply that the device or component referred to must have a specific orientation, nor should they be construed as limitations on the present invention.

[0038] Example:

[0039] See Figure 1 As shown, the present invention provides a vibration structure disposed on a main support structure, including a shaped panel 5, a vibration panel 6, and a vibration assembly. The first side of the shaped panel 5 is connected to the main support structure, and the second side of the shaped panel 5 is partially connected to the first side of the vibration panel 6 so that the vibration panel 6 fits the shaped panel 5 and has a vibration space. The second side of the vibration panel 6 contacts the vibrating material, and the vibration assembly passes through the shaped panel 5 and is connected to the vibration panel 6.

[0040] Specifically, the vibration assembly is configured as an attached vibrator 8 or an inserted vibrator 11; or, the vibration assembly is configured as a combination of an attached vibrator 8 and an inserted vibrator 11.

[0041] Specifically, equidistant plug holes and notches are provided at corresponding positions around the shaped panel 5 and the vibrating panel 6. The shaped panel 5 and the vibrating panel 6 are welded and fixed together around the perimeter through the plug holes and notches, thereby achieving a rigid connection between the vibrating panel 6 and the shaped panel 5 around the perimeter, while the remaining parts are connected by contact, so as to reduce the contact points between the vibrating panel 6 and the trolley frame 2. At the same time, the shaped panel 5 and the vibrating panel 6 are only welded together around the perimeter, while the other parts are only attached together (that is, the end faces of the shaped panel 5 and the vibrating panel 6 that are in contact with each other are only attached together and there are no other connections), so that the vibrating panel 6 has the maximum degree of freedom.

[0042] In addition to the above structure, in order to create a larger vibration space, a separator is provided between the shaping panel 5 and the vibrating panel 6. The separator is preferably a structural component with elastic effect (specifically, it can be a rubber pad, spring, etc.) to increase the amplitude of the vibrating panel 6 and make the vibration effect better.

[0043] In addition to the above structure, to ensure the demolding effect of the vibrating material, a release agent layer is also provided on the end face of the vibrating panel 6 that is in contact with the vibrating material.

[0044] In addition to the above structure, to facilitate the deformation of the working surface, the thickness of the vibrating panel 6 is less than the thickness of the shaping panel 5.

[0045] The present invention also provides a lining trolley, including a template assembly 1, a trolley frame 2, a support rod assembly 3, and a traveling mechanism 4; the template assembly 1 and the trolley frame 2 are rigidly connected by bolts; one end of the support rod assembly 3 is hinged to the trolley frame 2, and the other end of the support rod assembly 3 is hinged to the template assembly 1 (that is, there is a hinge point between one end of the support rod assembly 3 and the trolley frame 2, and a hinge point between the other end of the support rod assembly 3 and the cross plate assembly 1), so that the support rod assembly 3 uses the trolley frame 2 as the load-bearing point to drive the template assembly 1 for support and retraction, thereby completing the erection and demolding actions of the trolley vibrating material pouring; the trolley frame 2 and the traveling mechanism 4 are rigidly connected by bolts; the traveling mechanism 4 is used to move the double-layer panel vibratory lining trolley on the workbench or ground. Preferably, the template assembly 1 is configured to include a top mold and a side mold that are hinged to each other. Both the top mold and the side mold are composed of a template frame, a vibrating device and other structural components (specifically, in addition to the template frame, the other structures of the top mold and the side mold refer to the prior art); the template assembly 1, the trolley frame 2, the strut assembly 3 and the traveling mechanism 4 are interconnected to form the main support structure.

[0046] See Figure 2 As shown, the vibrating device includes a shaping panel 5, a vibrating panel 6, and a vibrating assembly. The shaping panel 5 and the vibrating panel 6 are connected to each other to form a double-layer panel structure. The shaping panel 5 is the main structure of the template assembly 1 and is connected to the trolley frame 2. The vibrating panel 6 is the working surface of the template assembly 1 and is used for contact with the vibrating material.

[0047] The molding panel 5 is provided with mounting holes for connecting with the vibrator mounting plate 7. The attached vibrator 8 is installed on the vibrator mounting plate 7. The attached vibrator 8 transmits the excitation force to the material to be vibrated through the molding panel 5. The attached vibrator 8 directly vibrates the molding panel 5 and has no contact with the vibrator panel 6. In this way, the excitation force of the attached vibrator 8 on the material to be vibrated can reach the maximum value.

[0048] Optionally, the length and width of the vibrating panel 6 are smaller than those of the shaping panel 5, and the vibrating panel 6 is provided with multiple pieces spaced apart from each other. The multiple vibrating panels 6 are evenly spaced along the circumferential direction of the template frame. After the multiple vibrating panels 6 are connected to the shaping panel 5, gaps and staggers are provided between the working surfaces of two adjacent templates of the double-layer panel vibrating lining trolley (i.e., between two adjacent vibrating panels 6).

[0049] The vibrator mounting plate 7 and the attached vibrator 8 are provided with multiple sets of equipment that correspond one-to-one with the multiple vibrator panels 6.

[0050] Optionally, the vibrator mounting plate 7 is welded to the middle of the template frame (specifically, the vibrator mounting plate 7 is preferably configured to include a first vertical plate, a horizontal plate and a second vertical plate connected in sequence, the first vertical plate and the second vertical plate are respectively set between two adjacent plastic panels 5 and fixedly connected to the vibrating panel 6, and the attached vibrator 8 is installed on the horizontal plate) without a connection position. After the attached vibrator 8 is installed, it makes the vibrating panel 6 generate the largest possible amplitude and acceleration, thereby increasing the vibration of the material.

[0051] Optionally, since there is no rigid connection in the longitudinal direction between adjacent vibratory panels 6, the excitation force of a single attached vibrator 8 cannot be transmitted to the adjacent vibratory panels 6. Consequently, the unvibrated vibratory panels 6 cannot vibrate the material, resulting in relatively poor forming quality of the material at their respective locations. Based on this, the present invention welds a vibrator mounting plate 7 to the middle position inside two adjacent vibratory panels 6 arranged along the longitudinal direction of the template frame, and installs an attached vibrator 8 on the vibrator mounting plate 7. This ensures that each vibratory panel 6 has a vibration source, thereby ensuring the forming quality of the material at different locations.

[0052] Optionally, regardless of whether it is the top mold or the side mold, the attached vibrator 8 is only connected to the vibrating panel 6 and has no connection point with the trolley frame 2. Therefore, the force exerted by the attached vibrator 8 on the trolley frame 2 is small.

[0053] In addition to the above structure, see Figure 3 As shown, this double-panel vibratory lining trolley, in addition to using double-panel structures for both the top and side forms, can also be configured as follows: the top form is a double-panel structure, and the side forms are single-panel structures (see...). Figure 5 (as shown), or, the top mold is a single-layer panel and the side mold is a double-layer panel; wherein, the end of the single-layer panel 10 is attached to the end of the vibrating panel in the double-layer panel 9 (the end of the single-layer panel 10 is not in contact with the shaping panel).

[0054] In addition to the above structure, see also Figure 4 As shown, the vibration method in this double-layer panel vibratory lining trolley can be configured not only by installing an attached vibrator 8 on the vibratory panel of the double-layer panel, but also by a combination of installing an attached vibrator 8 and an inserted vibrator 11 on a single-layer panel 10. The attached vibrator 8 on the single-layer panel 10 performs range-based vibration (for example, if the side formwork is single-layered, since the side formwork is mainly connected to the trolley frame 2 by a hinged connection through the strut assembly, the side formwork has a large degree of freedom of vibration, so its effect is only slightly weaker than that of the double-layer panel structure), while the inserted vibrator 11 can perform concentrated vibration in localized areas.

[0055] Optionally, the method for installing the immersion vibrator 11 on the single-layer panel 10 is as follows:

[0056] Mounting holes for an insert vibrator 11 are made on the single-layer panel 10. The vibrating rod of the insert vibrator 11 extends into the material to be vibrated and is then returned to the device after the work is completed.

[0057] As a further embodiment of the present invention, the method for vibration compaction using the double-layer panel vibratory lining trolley described above is as follows:

[0058] The vibrating element (which can be any one of an attached vibrator 8, an immersion vibrator 11, or a combination of both) vibrates the material (mixture, such as concrete) through a vibrating working surface (the vibrating working surface is the vibrating panel 6). During vibration, it ensures that all areas of the working surface except for rigid connection points are vibrated, with the excitation force reaching its maximum at the location where the vibrating element is installed. This ensures that the area in contact with the working surface is vibrated, avoiding point-based vibration that could lead to incomplete compaction.

[0059] As a further embodiment of the present invention, see Figure 6 As shown, the vibration structure provided by this invention can also be applied to box girder formwork. Specifically, the connection method of the vibration structure applied to the box girder formwork is as follows: the shaped panel 5 and the vibration panel 6 are connected to each other to form a double-layer panel structure; the shaped panel 5 is connected to the main support structure 01; the vibration panel 6 is in contact with the vibrating material 02; the vibrator (attached vibrator 8 or inserted vibrator 11) is connected to the vibration panel 6 so as to transmit the excitation force to the vibrating material 02 through the vibration panel 6. Preferably, the connection relationship between the vibration structure applied to the box girder formwork and other structures in the box girder formwork refers to the prior art.

[0060] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
