[0027] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0029] like Figure 1 and Figure 2 As shown, a template trolley with easy assembly and disassembly for comprehensive pipe corridor construction described in one embodiment of the utility model comprises a trolley frame 1, a top template 2 is arranged on the top of the trolley frame 1, corner templates 201 are hinged on both sides of the top template 2, side templates 3 are arranged on both sides of the trolley frame 1, and a quick-release part 4 connecting the top of the side template 3 and the bottom of the corner template 201 is arranged between the two, and the contact surface of the side template 3 and the corner template 201 is sealed and abutted.

[0030] Before construction, first install the top formwork 2 on the trolley frame 1, connect the corner formwork 201 to the top formwork 2 through a hinge mechanism, and install the side formwork 3 on both sides of the trolley frame 1. Place the formwork trolley at the predetermined position, adjust the positions of the top formwork 2 and the side formwork 3 according to the casting requirements, and adjust the corner formwork 201 and the side formwork 3 to form a suitable joint. Use the quick-release parts 4 to connect the side formwork 3 to the corner formwork 201. Check all joints to ensure that the contact surface between the side formwork 3 and the corner formwork 201 is sealed and abutted to prevent slurry leakage during casting. Start casting construction, and after the concrete solidifies, remove the quick-release parts 4, quickly disassemble the side formwork 3 and the corner formwork 201, and then demold the formwork trolley.

[0031] During the disassembly process of the traditional formwork trolley, since bolts and other fasteners are used for connection, the disassembly process is cumbersome and time-consuming. However, the present formwork trolley uses a quick-release part 4 to connect the side formwork 3 and the corner formwork 201, making the disassembly process simple and fast. The convenience and stability of the quick-release part 4 enable the operator to quickly lock and release the formwork, greatly shortening the disassembly time. At the same time, since the disassembly process is simplified, the manpower input is reduced, and the construction efficiency is further improved. In addition, since the slurry leakage is effectively prevented, the workload of later finishing and cleaning is reduced, and the construction cost is further reduced.

[0032] The joint between the top formwork 2 and the side formwork 3 of the formwork trolley is a key part prone to slurry leakage. The present formwork trolley achieves sealed contact between the contact surface of the side formwork 3 and the corner formwork 201 to ensure the tightness of the joint and effectively prevent slurry from leaking from the joint during the pouring process. This not only improves the pouring quality and reduces the workload of later finishing, but also avoids the problem of wall adhesion to the formwork trolley caused by slurry leakage, thereby reducing the difficulty of demoulding and further improving construction efficiency.

[0033] like Figure 2 As shown, in a preferred embodiment, a first connecting plate 202 is provided at the bottom of the corner template 201, and a plurality of first connecting holes 203 are provided on the first connecting plate 202. A second connecting plate 301 in contact with the first connecting plate 202 is provided on the top of the side template 3, and a plurality of second connecting holes 302 corresponding to the first connecting holes 203 are provided on the second connecting plate 301. A quick-release component 4 passes through the first connecting hole 203 and the second connecting hole 302 to connect the first connecting plate 202 and the second connecting plate 301. The quick-release component 4 is an aluminum film plate pin or buckle.

[0034] During installation, first install the first connecting plate 202 at the bottom of the corner template 201, and a plurality of first connecting holes 203 are provided on the first connecting plate 202. Similarly, the second connecting plate 301 in contact with the first connecting plate 202 is installed on the top of the side template 3, and the second connecting holes 302 corresponding to the first connecting holes 203 are provided on the second connecting plate 301. Prepare a corresponding number of aluminum film plate pins, including pins and pin pieces. Align the bottom of the corner template 201 with the top of the side template 3 so that the first connecting plate 202 is in close contact with the second connecting plate 301, and the first connecting hole 203 corresponds to the second connecting hole 302. Pass the pin through the corresponding first connecting hole 203 and the second connecting hole 302, and then insert the pin piece into the pin. And use a hammer or other tool to nail the pin piece tightly so that the first connecting plate 202 and the second connecting plate 301 are tightly connected together. Ensure that all quick-release parts 4 are tightened and the connection is stable and reliable. After the installation of the quick-release parts 4 is completed, carefully check the connection between the corner formwork 201 and the side formwork 3. Make sure that all joints are tight and seamless without the risk of leakage.

[0035] By using the quick-release parts 4 to connect the corner formwork 201 and the side formwork 3, the operator can quickly complete the connection and disassembly work, greatly improving the construction efficiency. The quick-release parts 4 make the connection process simple and fast, reducing unnecessary operation steps and time consumption. The first connecting plate 202 and the second connecting plate 301 are tightly connected together by the aluminum film plate pins to form a stable connection structure, which not only ensures the stability of the formwork trolley during the pouring process, but also effectively prevents the slurry from leaking from the joints. Since the installation and disassembly process of the quick-release parts 4 is simple and fast, the manpower input and working time costs are reduced. In addition, since the workload of later finishing and cleaning is reduced, the construction cost is further reduced. By using the quick-release parts 4 to connect the corner formwork 201 and the side formwork 3, the formwork trolley can adapt to different construction environments and needs more flexibly. The versatility and interchangeability of the quick-release parts 4 make the formwork trolley easy to modify and upgrade, improving its use value and applicability.

[0036] like Figure 2 As shown, in a preferred embodiment, a receiving groove 303 is provided on the top of the side formwork 3 , a sealing member 304 is provided in the receiving groove 303 , and a height of the sealing member 304 is not less than a depth of the receiving groove 303 .

[0037] By setting a receiving groove 303 on the top of the side formwork 3 and installing a seal 304, the sealing of the contact surface between the corner formwork 201 and the side formwork 3 is improved. The seal 304 can fill the small gap between the two to prevent the slurry from leaking from the joint during the pouring process. Due to the presence of the seal 304, the risk of leakage is effectively reduced, making the wall after pouring more flat and smooth, which not only improves the pouring quality, but also reduces the workload of later finishing. Since the workload of leakage and finishing is reduced, the construction personnel can focus more on the pouring work itself, which improves the construction efficiency. At the same time, the installation process of the seal 304 is relatively simple and quick, which improves the construction efficiency and speeds up the construction progress. The seal 304 is a rubber waterstop. According to the size and shape of the receiving groove 303, a suitable rubber waterstop is selected as the seal 304. Ensure that the width, length and thickness of the rubber waterstop can meet the sealing requirements.

[0038] like Figure 1 , Figure 4 and Figure 5 As shown, in a preferred embodiment, a walking mechanism 5 is provided at the bottom of the trolley frame 1, and the walking mechanism 5 includes a hydraulic motor 501, and the hydraulic motor 501 is transmission-connected to a driving wheel 502, and the trolley frame 1 is rotationally connected to a driven wheel 503 on one side of the driving wheel 502, and a track 504 is provided below the driving wheel 502 and the driven wheel 503.

[0039] The stable movement of the template trolley is achieved through the walking mechanism 5 at the bottom of the trolley frame 1. First, the operator starts the hydraulic motor 501, which is the power source of the walking mechanism 5. The hydraulic motor 501 quickly converts hydraulic energy into mechanical energy, and drives the driving wheel 502 to start rotating through the transmission device. At the same time, the driven wheel 503 rotates with the driving wheel 502, and the two jointly support and drive the trolley frame 1 to move. As the driving wheel 502 rotates, the entire trolley frame 1 moves forward smoothly along the preset track 504. The operator can achieve precise control of the moving speed and direction of the trolley frame 1 by controlling the speed and direction of the hydraulic motor 501. The walking mechanism 5 not only improves the construction efficiency, enables the template trolley to reach the specified position quickly and accurately, but also enhances the stability and safety of the template trolley.

[0040] like Figure 6As shown, in a preferred embodiment, a travel limiting mechanism 6 is provided at the bottom of the trolley frame 1, and the travel limiting mechanism 6 includes a crossbeam 601, a sliding frame 602 is slidably provided under the crossbeam 601, a sliding rod 603 and a bidirectional screw 604 are provided on the sliding frame 602, the bidirectional screw 604 is provided with two sections of threads with different rotation directions, two sliding plates 605 are slidably provided on the sliding rod 603, the two sliding plates 605 are respectively screwed with the two sections of threads of the bidirectional screw 604, and pulleys 606 are rotatably provided on the opposite sides of the two sliding plates 605. Rotating the bidirectional screw 604 drives the two pulleys 606 to approach each other and engage with the track 504 or to move away from each other and separate from the track 504.

[0041] When the trolley frame 1 needs to move, the operator will rotate the bidirectional screw 604 by using a tool such as a wrench, or by setting a hydraulic drive motor to drive the bidirectional screw 604. Due to the special design of the bidirectional screw 604, the two sliding plates 605 will approach each other, driving the pulley 606 to engage with the track 504, which can effectively prevent the driving wheel 502 or the driven wheel 503 from accidentally derailing during the movement, thereby ensuring the stability and safety of the trolley frame 1.

[0042] When the top template 2 needs to be raised or lowered, the pulleys 606 of the travel limiting mechanism 6 are driven to move away from each other, so that the pulleys 606 are separated from the track 504, and the trolley frame 1 will not be restricted by the track 504 to affect the raising or lowering of the top template 2. The operator can adjust the height of the top template 2 as needed to perform construction operations such as pouring.

[0043] In this embodiment, the travel limiting mechanism 6 can effectively prevent the trolley frame 1 from derailing due to external force or improper operation during movement, greatly improving the safety of construction. The travel limiting mechanism 6 can not only realize the positioning and limiting of the trolley frame 1, but also can be separated from the track 504 when necessary, so that the top template 2 can be freely raised and lowered, meeting the needs of different construction scenes and enhancing the flexibility of construction. By simply rotating the bidirectional screw 604, the pulley 606 can be engaged and separated from the track 504, and the operation process is simple and fast, which improves the construction efficiency.

[0044] like Figure 6 As shown, in a preferred embodiment, the crossbeam 601 is an I-beam, and blocks 607 are respectively provided on both sides of the top of the sliding frame 602 , and the blocks 607 are slidably engaged with the flanges on both sides of the bottom of the crossbeam 601 .

[0045] In this embodiment, the I-beam not only ensures the strength and stability of the structure, but also makes the entire travel limit mechanism 6 more durable. By adjusting the position of the sliding frame 602 on the crossbeam 601, the operator can flexibly adjust the position of the travel mechanism 5 according to the tracks 504 of different widths, ensuring that the pulley 606 can be accurately aligned with the track 504 to achieve stable engagement. This allows the template trolley to adapt to the needs of different construction environments, improving its adaptability and flexibility.

[0046] like Figure 2 As shown, in a preferred embodiment, legs 7 are respectively provided on both sides of the bottom of the trolley frame 1, and the legs 7 include a lifting hydraulic cylinder 701, each lifting hydraulic cylinder 701 is provided with a hydraulic lock 702, the piston rod of the lifting hydraulic cylinder 701 is vertically downward, and a pad 703 is provided at the bottom of the piston rod of the lifting hydraulic cylinder 701.

[0047] Before the trolley frame 1 moves to the designated position, the legs 7 are in a retracted state, the piston rod of the lifting hydraulic cylinder 701 is fully retracted, and the pad 703 does not contact the casting bottom plate. When the walking mechanism 5 moves the trolley frame 1 to the designated position, the walking limit mechanism 6 releases the track 504, and the operator controls the lifting hydraulic cylinder 701 to start, so that the piston rod extends vertically downward. The telescopic action of the lifting hydraulic cylinder 701 is controlled by the hydraulic system, and the extension length can be accurately adjusted. When the piston rod is extended to the predetermined position, the pad 703 contacts the casting bottom plate to provide support for the trolley frame 1. By controlling the telescopic movement of the lifting hydraulic cylinder 701, the distance between the pad 703 and the casting bottom plate can be adjusted, and then the overall height of the trolley frame 1 can be adjusted, so as to achieve precise control of the height of the top template 2. After the legs 7 are adjusted to the appropriate position, the hydraulic lock 702 will start to ensure that the piston rod of the lifting hydraulic cylinder 701 is fixed in position, so as to prevent the template from falling due to the pressure relief of the lifting hydraulic cylinder 701 during casting or other construction processes.

[0048] Through the precise control of the lifting hydraulic cylinder 701, the height of the top template 2 can be adjusted to meet the requirements of high-precision construction. The design of the legs 7 provides stable support for the trolley frame 1, enhancing its stability during the construction process, especially when performing heavy-load operations such as pouring, which can effectively prevent the trolley frame 1 from sinking or shaking. The addition of the hydraulic lock 702 ensures the position stability of the legs 7 after being adjusted into place, prevents the lifting hydraulic cylinder 701 from depressurizing, and thus improves the safety of construction.

[0049] like Figure 1 and Figure 3As shown, in a preferred embodiment, the top template 2 includes a steel back rib 204 connected to the trolley frame 1, a first frame 205 is provided on the top of the steel back rib 204, a first template 206 is provided on the top of the first frame 205, and a demoulding portion is provided on the model surface of the first template 206. The demoulding portion can be a demoulding agent applied to the model surface or a glass fiber board provided on the model surface.

[0050] A plurality of lifting holes 207 are formed on the first template 206 , and blocks 208 are disposed in the lifting holes 207 .

[0051] When installing the top formwork 2, first connect the steel back rib 204 to the trolley frame 1 to ensure the overall stability of the top formwork 2. Then install the first frame 205 on the top of the steel back rib 204, and firmly connect the two by welding or fasteners. Finally, connect the first formwork 206 to the first frame 205 by welding or fasteners to ensure that the formwork is flat. The provision of the demoulding part helps to easily separate the formwork from the concrete after the concrete pouring is completed, thereby improving the construction efficiency.

[0052] During the hoisting process of the top template 2, the hoisting is performed through the multiple hoisting holes 207 opened on the first template 206. The position and number of the hoisting holes 207 can be designed according to the hoisting requirements to ensure that the template is evenly stressed during the hoisting process to avoid deformation or damage. During hoisting, use appropriate hoisting equipment to pass the hoisting rope through the hoisting hole 207 and fix it. The block 208 is used to block the hoisting hole 207 after hoisting to ensure the flatness of the template.

[0053] In this embodiment, the combination of the steel back rib 204 and the first frame 205 effectively enhances the overall stability of the top template 2. This makes the top template 2 less likely to deform when subjected to the pressure of concrete pouring, ensuring the quality and safety of construction. The provision of the demoulding portion enables the template to be easily separated from the concrete surface after the concrete pouring is completed, reducing the manpower and time costs in the demoulding process and improving the construction efficiency.

[0054] like Figure 2 As shown, in a preferred embodiment, the side template 3 includes a second frame 305, a translation mechanism 8 is connected between the second frame 305 and the trolley frame 1, a second template 306 is provided on the side of the second frame 305 away from the trolley frame 1, and a demoulding portion is provided on the model surface of the second template 306. The translation mechanism 8 includes a translation hydraulic cylinder 801 provided on the upper part of the trolley frame 1 and a positioning hydraulic cylinder 802 provided on the lower part.

[0055] When installing the side formwork 3, first connect the translation mechanism 8 to the trolley frame 1 to ensure that the connection is firm and reliable. Then connect the second skeleton 305 to the translation mechanism 8 to ensure that the side formwork 3 can move smoothly to both sides. Before the pouring operation begins, the operator controls the translation mechanism 8 to move the side formwork 3 to a predetermined position to form a complete pouring space together with the top formwork 2. During the translation process, the movement trajectory of the side formwork 3 is accurate and smooth, ensuring the alignment and sealing between the formworks. When the side formwork 3 moves to the correct position, the pouring of concrete begins. The model surface of the side formwork 3 is also provided with a demoulding portion, which helps to smoothly separate the formwork from the concrete after the pouring is completed. After the concrete solidifies, the side formwork 3 is moved toward the direction close to the trolley frame 1 by controlling the translation mechanism 8 to achieve demoulding and prepare for the next pouring operation.

[0056] The movement of the side formwork 3 is controlled by the translation mechanism 8, which greatly simplifies the installation and removal process of the formwork and improves the construction efficiency. At the same time, the flexible movement of the side formwork 3 also makes the pouring operation more continuous and efficient. The translation mechanism 8 makes the movement process of the side formwork 3 smooth and controllable, reducing the risk of safety accidents caused by the movement of the formwork. At the same time, the setting of the demoulding part also reduces the resistance and risk in the demoulding process, further improving the safety of construction.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
