Description

Technical Field

[0001] The present application relates to the field of bridge superstructure construction, and in particular to a segmental glued beam inner box operation trolley and a method of using the trolley. Background Art

[0002] The segmental prefabricated glued assembly (abbreviated as glued assembly) bridge construction technology is very mature abroad. As early as the 1960s, European and American countries have begun to use segmental prefabricated glued assembly technology to build bridges. At present, in developed countries such as Europe, the United States, and Japan, prestressed concrete simply supported beams and continuous beams using glued joint construction technology have been widely used in highways, high-speed railways, and urban rails, becoming the main construction method for segmental glued beams.

[0003] In recent years, this bridge structure has also been widely used in highway bridge construction in my country. The adhesive joints use adhesive materials such as epoxy resin, and the wet joints are in the form of concrete or dry hard cement mortar filled between adjacent prefabricated beam sections. The dry joints are not filled with connecting materials, and the connection is completely achieved by segmental tenons and prestressing. Because the top plate of the inner box of the segmental glued beam is too high, the glue application, overflow glue treatment, and reserved hole treatment of the top plate require the help of an external construction platform. The existing construction platform structure is relatively simple and it is difficult to adapt to the construction of segmental glued beam inner boxes of various sizes. At the same time, due to the different cross-sectional sizes of the inner box, the construction platform cannot be moved across segments, which brings great inconvenience to the construction work and has relatively low economic benefits. Summary of the invention

[0010] In combination with the first aspect, in one embodiment, the bottom longitudinal bridge rod of the frame extends outside the frame toward both ends along the longitudinal bridge side, and two oblique long telescopic rods close to both sides of the side intersect and are hinged to the nearest vertical telescopic rod, and an oblique short telescopic rod for reinforcing the frame is provided at the hinge, one end of the oblique short telescopic rod is located at the hinge, and the other end is hinged to the longitudinal bridge rod.

[0011] In combination with the first aspect, in one embodiment, guardrails are hinged on both sides of the top surface of the main body along the longitudinal bridge direction; during the glue application operation, the guardrails are vertically arranged on the top surface of the main body; when passing through the hole to the inner box of the next segment of the glued beam, the guardrails are folded and placed on both sides of the main body.

[0012] In a second aspect, an embodiment of the present application provides a method for using a segmental glued beam inner box operation trolley as described in any one of the above embodiments, the steps comprising:

[0013] During the glue spreading operation, adjust the telescopic amount of the horizontal bridge telescopic rod and the telescopic amount of the vertical telescopic rod until the size of the work trolley is the target size, wherein the target size is smaller than the size of the inner box; when passing through the hole to the inner box of the next segment glued beam, adjust the telescopic amount of the horizontal bridge telescopic rod until the width of the frame is smaller than the hole width, and adjust the telescopic amount of the vertical telescopic rod until the height of the frame is smaller than the hole height; extend the vertical telescopic rod, lift the frame to the target height, and move the work trolley in the direction of passing through the hole, wherein the target height is the vertical height of the bottom of the hole; when a vertical telescopic rod is about to enter the hole, retract the vertical telescopic rod so that its height is smaller than the hole height, and move the work trolley in the hole; after the vertical telescopic rod passes through the hole, extend the vertical telescopic rod so that the main wheel at its bottom lands on the bottom of the inner box of the next segment glued beam, and the work trolley continues to move; perform the hole entry operation of other vertical telescopic rods until the work trolley is completely through the hole.

[0030] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] The embodiment of the present application provides a segmental glued beam inner box operation trolley and a method of using the same, which can solve the problem that the existing construction platform is difficult to adapt to the construction of segmental glued beam inner boxes of various sizes and cannot achieve cross-segment mobile operations.

[0032] In a first aspect, a segmental glued beam inner box operation trolley is provided.

[0033] Reference Figure 1-5 , Figure 1 It is a schematic diagram of the inner box operation trolley of the segment glued beam in the embodiment of the present application; Figure 2 for Figure 1 Side view of the middle work trolley; Figure 3 for Figure 1 Schematic diagram of the first state of the middle working trolley when passing through the hole; Figure 4 for Figure 1 Schematic diagram of the second state when the middle working trolley passes through the hole; Figure 5 for Figure 1 The third state diagram of the working trolley passing through the hole. Figure 1-5 As shown, in one embodiment, the segment glued beam inner box operation trolley includes a main body 1 and a walking mechanism 2. The main body 1 includes a plurality of longitudinal bridge rods 11, a plurality of transverse bridge telescopic rods 12 and a plurality of vertical telescopic rods 13, which are interconnected and form a frame 14; the walking mechanism 2 includes a plurality of main wheels 21 installed at the bottom ends of the vertical telescopic rods 13, and also includes a plurality of auxiliary wheels 22 installed at the bottom longitudinal bridge rods 11 of the main body 1 and distributed along the length direction thereof. During the glue spreading operation, the main body 1 is adjusted to the target size, and all the main wheels 21 and auxiliary wheels 22 are at the same horizontal plane height. When passing through the hole to the next segment glued beam inner box, the frame 14 is raised to the target height, the width of the frame 14 is less than the hole width, the height of the frame 14 is less than the hole height, and the vertical telescopic rods 13 located at both ends of the hole are extended, and the vertical telescopic rods 13 located in the hole are contracted.

[0034] Among them, the transverse bridge telescopic rod 12 is a telescopic rod arranged along the transverse bridge direction, which can support the main body 1 to adjust the size in the transverse bridge direction; the vertical telescopic rod 13 is a telescopic rod arranged along the vertical direction, which can support the main body 1 to adjust the size in the vertical direction, and the longitudinal bridge rod 11 can be a fixed rod arranged along the longitudinal bridge direction, or a telescopic rod arranged along the longitudinal bridge direction. When the longitudinal bridge rod 11 is a fixed rod, it cannot support the main body 1 to adjust the size in the longitudinal bridge direction; when the longitudinal bridge rod 11 is a telescopic rod, it can support the main body 1 to adjust the size in the longitudinal bridge direction. In addition, all telescopic rods can be formed by two hollow steel pipes, one large and one small, and the connection is fixed by a pin.

[0035] The main wheel 21 is installed at the bottom end of the vertical telescopic rod 13, and can move up and down along the vertical direction with the bottom end of the vertical telescopic rod 13. When the vertical telescopic rod 13 is extended and the bottom end of the vertical telescopic rod 13 does not move, the main wheel 21 always keeps in contact with the bottom of the box of the segment glued beam, and the frame 14 will be lifted. It should be noted here that the term "frame 14" in this embodiment only includes a structure formed by connecting a plurality of bridge rods, a plurality of transverse bridge telescopic rods 12 and a plurality of vertical telescopic rods 13 to each other. The part extending due to the extension of the telescopic rod can be regarded as a part of the main body 1, but does not belong to the scope of the frame 14. The auxiliary wheel 22 is installed on the longitudinal bridge rod 11 at the bottom of the main body 1. If the longitudinal bridge rod 11 is a fixed rod, the auxiliary wheel 22 cannot move in the longitudinal bridge direction; if the longitudinal bridge rod 11 is a telescopic rod, it can.

[0036] When using the work trolley to apply glue to the inner box of the segmental glued beam, each type of segmental glued beam inner box will correspond to a target size of the main body 1, which is calculated in advance by the staff. Therefore, in this embodiment, the target size can be used as the existing technology, the main body 1 can be adjusted to the target size, and all the main wheels 21 and auxiliary wheels 22 are at the same horizontal height, and can work together on the bottom of the inner box to support the entire weight of the main body 1.

[0037] When using the work trolley to pass through the hole to the inner box of the next segment glued beam, the main body 1 can use the walking mechanism 2 to achieve the hole. The so-called "hole" actually refers to the end section opening of the inner box of the segment glued beam, which can directly reach the inner box of the next segment glued beam. Because the hole size of the inner box of the segment glued beam is small, and the hole size of each type of segment glued beam inner box is different. Therefore, by adjusting the size of the transverse telescopic rod 12 and the vertical telescopic rod 13, the frame 14 can be raised to the target height, the width of the frame 14 is less than the hole width, the height of the frame 14 is less than the hole height, and the vertical telescopic rods 13 at both ends of the hole are extended, and the vertical telescopic rods 13 located in the hole are contracted.

[0038] In this embodiment, by adjusting the size of the transverse telescopic rod 12 and the vertical telescopic rod 13 of the main body 1, the work trolley is adjustable in the transverse and vertical directions. The most important thing is that the staff can adjust the transverse and vertical dimensions of the work trolley according to the size of the inner box of the segment glued beam, so that it is suitable for the construction of segment glued beams of various sizes, which brings great convenience to the staff in the glue spreading operation, and the economic benefits are significant. When the work trolley is used to pass through the hole to the inner box of the next segment glued beam, the size of the transverse telescopic rod 12 and the vertical telescopic rod 13 of the main body 1 can also be adjusted to ensure that the work trolley can smoothly enter the hole. By adjusting the telescopic amount of the vertical telescopic rod 13 and using the main wheel 21 and the auxiliary wheel 22 together, it can be ensured that the work trolley can pass through the hole continuously, and the stability during the hole can also be guaranteed, and it is not easy to tilt or be damaged by friction on the inner wall of the hole. Through this embodiment, the problem that the existing construction platform is difficult to adapt to the construction of the inner box of the segment glued beam of various sizes and cannot realize the cross-segment mobile operation is solved.

[0039] Further, in one embodiment, if Figure 1 As shown, the longitudinal bridge rod 11 is a telescopic rod, and when passing through the hole to the inner box of the glued beam of the next section, the longitudinal bridge rod 11 shrinks. In this embodiment, the longitudinal bridge rod 11 is a telescopic rod, which can support the main body 1 to adjust the size in the longitudinal bridge direction. When passing through the hole to the inner box of the glued beam of the next section, the longitudinal bridge rod 11 can shrink, so that the length of the main body 1 becomes shorter, and the hole can be passed faster, making the construction more efficient and convenient.

[0040] Further, in one embodiment, if Figure 1 and Figure 2 As shown, the main body 1 also includes a plurality of oblique telescopic rod assemblies for reinforcing the main body 1, and at least one oblique telescopic rod assembly is installed on each side of the frame 14. In this embodiment, the oblique telescopic rod assembly can be used to reinforce the main body 1. By installing at least one oblique telescopic rod assembly on each side of the frame 14, the frame 14 can be made more secure, and the frame 14 will not be easily deformed when the worker stands on the work trolley to perform the glue application operation.

[0041] Further, in one embodiment, if Figure 1 and Figure 2As shown, the oblique telescopic rod assembly includes two oblique long telescopic rods 15, and the two oblique long telescopic rods 15 are in an inverted "V" shape, and their intersecting ends are hinged to the top telescopic rod on the side where they are located, and the other two ends are hinged to the bottom telescopic rod on the side where they are located. In this embodiment, the oblique telescopic rod assembly includes two oblique long telescopic rods 15, and by arranging the two oblique long telescopic rods 15 in an inverted "V" shape, and making their intersecting ends hinged to the top telescopic rod on the side where they are located, and the other two ends are hinged to the bottom telescopic rod on the side where they are located, this inverted "V" design allows the work trolley to shrink to a smaller space when not in use, which is convenient for storage and carrying. At the same time, the two inverted "V"-shaped oblique long telescopic rods 15 and the bottom telescopic rod on the side where they are located form a triangular structure, which has good mechanical stability and can withstand large external forces and pressures, thereby improving the stability of the main body 1.

[0042] Further, in one embodiment, if Figure 1 As shown, when a side of the frame 14 is provided with an oblique telescopic rod assembly, the intersection end is located at the midpoint of the top telescopic rod on the side, and the other two ends are respectively located at the two ends of the bottom telescopic rod on the side; when the side of the frame 14 is provided with multiple oblique telescopic rod assemblies, the multiple oblique telescopic rod assemblies are distributed between the top telescopic rod and the bottom telescopic rod on the side, and one end of the two oblique long telescopic rods 15 close to the two sides of the side are respectively hinged to the two ends of the bottom telescopic rod on the side. In this embodiment, when a side of the frame 14 is provided with an oblique telescopic rod assembly, the intersection end can be located at the midpoint of the top telescopic rod on the side, and the other two ends are respectively located at the two ends of the bottom telescopic rod on the side, so that it is more convenient to install, which can ensure that the oblique telescopic rod assembly can be extended and retracted together with other telescopic rods (including but not limited to the horizontal bridge telescopic rod 12, the longitudinal bridge rod 11 or the vertical telescopic rod 13, note: if the longitudinal bridge rod 11 here is a fixed rod, it cannot be extended and retracted, if it is a telescopic rod, it can be extended and retracted in the longitudinal bridge direction) and can also enhance the stability of the frame 14.

[0043] When a plurality of oblique telescopic rod assemblies are provided on the side of the frame 14, the plurality of oblique telescopic rod assemblies are distributed between the top telescopic rod and the bottom telescopic rod on the side, and one end of the two oblique long telescopic rods 15 close to the two sides of the side are respectively hinged to the two ends of the bottom telescopic rod on the side, wherein the plurality of oblique telescopic rod assemblies can be installed in a flat manner or in a cross manner. If there is an intersection, the intersecting oblique long telescopic rods 15 are hinged at the intersection to ensure that the plurality of oblique telescopic rod assemblies can be extended and retracted as usual, the structure is relatively compact, and the fixing effect on the frame 14 is relatively significant.

[0044] Further, in one embodiment, if Figure 1As shown, the side of the frame 14 along the longitudinal bridge direction, the longitudinal bridge rod 11 at the bottom thereof extends to the outside of the frame 14 toward both ends, and the two oblique long telescopic rods 15 near the two sides of the side respectively intersect and are hinged to the nearest vertical telescopic rod 13, and an oblique short telescopic rod 16 for reinforcing the frame 14 is provided at the hinge, one end of the oblique short telescopic rod 16 is located at the hinge, and the other end is hinged to the longitudinal bridge rod 11. In this embodiment, through the above structure, the overall structure of the frame 14 is more stable, and it will not be easily deformed when subjected to huge pressure and external force.

[0045] Further, in one embodiment, if Figure 1-5 As shown, the top surface of the main body 1 is hinged with guardrails 3 on both sides along the longitudinal bridge direction; when applying glue, the guardrails 3 are vertically arranged on the top surface of the main body 1; when passing through the hole to the inner box of the glued beam of the next section, the guardrails 3 are folded and placed on both sides of the main body 1. In this embodiment, by hingedly connecting the guardrails 3 on both sides of the top surface of the main body 1 along the longitudinal bridge direction, during the gluing operation, the guardrails 3 are vertically arranged on the top surface of the main body 1, which can effectively prevent the operators from falling from a height due to careless operation or loss of balance, thereby ensuring their life safety; when passing through the hole to the inner box of the glued beam of the next section, the guardrails 3 are folded and placed on both sides of the main body 1, which can reduce the adjustment amount of the vertical telescopic rod 13, making it convenient for the operation trolley to pass through the hole.

[0046] In some other embodiments, a staircase for workers to climb to the top surface of the main body 1 is detachably installed on the side of the main body 1, and a platform is set up on the top surface of the main body 1 for workers to walk on.

[0047] In a second aspect, a method for using the segment glued beam inner box operation trolley in any of the above embodiments is provided.

[0048] See also Figure 6 , Figure 6 for Figure 1 Flow chart of the use of the inner box operation trolley for the middle segment glued beam. Figure 6 As shown, the method for using the segmental glued beam inner box operation trolley includes the following steps.

[0049] Step S10, during the glue spreading operation, adjust the telescopic amount of the horizontal bridge telescopic rod 12 and the telescopic amount of the vertical telescopic rod 13 until the size of the operation trolley meets the target size, wherein the target size is smaller than the size of the inner box;

[0050] In this embodiment, after the bridge erection machine hoists each segment glued beam and lowers it to the designated position, during the glue spreading operation, the staff can assemble the work trolley in the inner box of the segment glued beam, and adjust the telescopic amount of the horizontal bridge telescopic rod 12 and the telescopic amount of the vertical telescopic rod 13 until the size of the work trolley meets the target size, so that the staff can easily complete the glue spreading on the top plate of the inner box with the help of the work trolley, ensure the construction quality, and make the construction more efficient and convenient. Among them, the target size is smaller than the inner box size. It is the size of the work trolley planned in advance according to the size of the inner box by the staff in order to better complete the glue spreading operation, so it is smaller than the size of the inner box.

[0051] It should be noted that when adjusting the size of the work trolley, the size of the work trolley can also be appropriately smaller than the target size. In this way, there is no need to be precise to a specific value, the adjustment is not troublesome, and the construction efficiency can be improved.

[0052] Step S20, when passing through the hole to the inner box of the next segment glued beam, adjust the telescopic amount of the transverse bridge telescopic rod 12 until the width of the frame 14 is smaller than the hole width, and adjust the telescopic amount of the vertical telescopic rod 13 until the height of the frame 14 is smaller than the hole height.

[0053] Step S30, extending the vertical telescopic rod 13, lifting the frame 14 to a target height, and moving the work trolley in the through-hole direction, wherein the target height is the vertical height of the hole bottom.

[0054] In this embodiment, when passing through the hole to the inner box of the next segment of the glued beam, the extension amount of the transverse telescopic rod 12 and the vertical telescopic rod 13 are adjusted to make the width of the frame 14 smaller than the hole width and its height smaller than the hole height. This ensures that when the work trolley passes through the hole, the frame 14 can enter the hole smoothly and will not be stuck in the hole.

[0055] Next, the frame 14 is lifted to the target height by extending the vertical telescopic rod 13 separately, and the work trolley is moved toward the through-hole direction, wherein the target height is the vertical height of the bottom of the hole. When the frame 14 is lifted to the target height, the auxiliary wheels 22 are also lifted to the target height along with the frame 14, and as the work trolley moves to the hole, the auxiliary wheels 22 can slide directly on the bottom of the hole.

[0056] In this embodiment, preferably, when the work trolley passes through the hole, the auxiliary wheel 22 passes through the hole earlier than the main wheel 21, so that the auxiliary wheel 22 can play a certain supporting role on the frame 14, reduce the force on the main wheel 21, and at the same time have a certain guiding role, making it easier for the main wheel 21 to enter the hole.

[0057] Step S40, when a vertical telescopic rod 13 is about to enter the hole, retract the vertical telescopic rod 13 so that its height is less than the hole height, and move the work trolley in the hole; after the vertical telescopic rod 13 passes through the hole, extend the vertical telescopic rod 13 so that the main wheel 21 at its bottom lands on the bottom of the inner box of the next segment of the glued beam, and the work trolley continues to move.

[0058] Step S50, performing the hole entry operation of other vertical telescopic rods 13 until the operation trolley completely passes through the hole.

[0059] In this embodiment, the work trolley moves toward the hole. When the vertical telescopic rod 13 is about to enter, the vertical telescopic rod 13 is retracted to make its height less than the hole height, and the work trolley continues to move in the hole, thereby achieving the purpose of the work trolley passing through the hole.

[0060] In addition, in the present embodiment, if the auxiliary wheel 22 enters the hole before the main wheel 21, the frame 14 can be supported together with the main wheel 21, which can not only reduce the operating pressure of the staff when the subsequent staff retracts the vertical telescopic rod 13, but also help to maintain the balance of the work trolley. At the same time, the auxiliary wheel 22 slides in the hole, indicating that a part of the work trolley has entered the hole, which provides a certain convenience for guiding the subsequent vertical telescopic rod 13 to enter the hole. After the vertical telescopic rod 13 passes through the hole, the vertical telescopic rod 13 is extended so that the main wheel 21 at its bottom lands on the bottom of the box of the next section of the glued beam, and the work trolley continues to move. In this way, the work trolley can stably land on the inner box of the next section of the glued beam, ensuring the stability of the work trolley. According to the above method, the other vertical telescopic rods 13 are operated to enter the hole until the work trolley is completely through the hole.

[0061] Further, in one embodiment, if Figure 3-5 As shown, when passing through the hole to the inner box of the next segment glued beam, before the vertical telescopic rod 13 is extended, the main wheel 21 and the auxiliary wheel 22 jointly support the work trolley; after the vertical telescopic rod 13 is extended, the main wheel 21 supports the work trolley.

[0062] In this embodiment, when passing through the hole to the inner box of the next segment glued beam, before the vertical telescopic rod 13 is extended, it means that the work trolley is currently in the preparation stage before passing through the hole. At this time, only the width and height of the work trolley are adjusted. All the main wheels 21 and all the auxiliary wheels 22 are still focused on the bottom of the inner box of the segment glued beam, and jointly support the work trolley, so that the work trolley is balanced. After extending the vertical telescopic rod 13, the work trolley is still in the preparation stage before passing through the hole, but the work trolley is lifted to the target height. At this time, only the main wheels 21 are focused on the bottom of the inner box to support the work trolley.

[0063] Further, in one embodiment, if Figure 3-5As shown, after the vertical telescopic rod 13 enters the hole, the height of the main wheel 21 outside the hole is lower than the height of the main wheel 21 inside the hole, and the height of the main wheel 21 inside the hole is flush with the height of all the auxiliary wheels 22.

[0064] In this embodiment, after the vertical telescopic rod 13 enters the hole, the height of the main wheel 21 outside the hole is lower than the height of the main wheel 21 inside the hole, which can support the work trolley outside the hole and keep the work trolley balanced; after the vertical telescopic rod 13 is retracted, the main wheel 21 will retract into the hole together with the end of the vertical telescopic rod 13. At this time, the height of the main wheel 21 in the hole is flush with the height of all the auxiliary wheels 22. In this way, after the auxiliary wheel 22 enters the hole, it can also slide in the hole to ensure the stability of the work trolley when passing through the hole.
