[0035] 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. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0037] like Figure 1 , Figure 7 and Figure 8 As shown, a formwork system for comprehensive pipe corridor construction described in one embodiment of the utility model includes a plurality of inner trolley formworks 100 and outer trolley formworks 200 arranged on both sides of the inner trolley formworks 100, the outer trolley formworks 200 include an outer formwork 201, a first running mechanism 209 is arranged below the outer formwork 201, the first running mechanism 209 is used to support the outer formwork 201 and the moving guide of the outer formwork 201, a second running mechanism 214 is arranged above the outer formwork 201, the second running mechanism 214 is used to pull the outer formwork 201 and the moving guide of the outer formwork 201 toward one side of the model cavity.

[0038] In this embodiment, by setting the first running mechanism 209 and the second running mechanism 214 on the outer template 201, the movement process of the outer template 201 becomes more efficient and stable, reducing the time and manpower required for installation and disassembly, making the entire construction process smoother, thereby significantly improving the construction efficiency. Secondly, the construction stability is enhanced. The traditional outer template 201 design often relies on the support of the steel cage, which has limited support force and unstable walking. In the above technology, the outer template 201 is supported and guided by the first running mechanism 209 and the second running mechanism 214, so that the outer template 201 is more stable during the movement process, reducing the risk of construction accidents caused by instability. In addition, the construction space requirement is optimized. Since the running mechanism is arranged on the upper and lower sides of the outer template 201, the structure is more compact and reasonable, and it is no longer necessary to dig too large a diameter to meet the construction requirements, which not only reduces the impact on the surrounding environment and reduces the construction difficulty, but also makes the construction space more effectively utilized, improves the construction efficiency, and reduces the construction cost.

[0039] like Fig. 9 and Fig.13As shown, in a preferred embodiment, the first running mechanism 209 includes a first translation guide rail 210, and a plurality of caster brackets 211 are arranged on the first translation guide rail 210, and casters 212 are rotatably connected to the caster brackets 211, and the outer circumferential surface of the caster 212 is provided with a V-shaped groove, and a V-shaped track 213 matching the V-shaped groove is arranged above the caster 212, and the V-shaped track 213 is connected to the outer template 201.

[0040] During construction, first install the first translation guide rail 210 at a preset position according to the construction requirements and the size of the outer template 201. Ensure that the first running mechanism 209 can stably support the movement of the outer template 201. Next, install a plurality of caster brackets 211 on the first translation guide rail 210, and rotatably connect casters 212 on each caster bracket 211. The casters 212 enable the outer template 201 to move smoothly through the rolling of the casters 212. A V-shaped groove is provided on the outer circumferential surface of each caster 212, and the V-shaped groove cooperates with the V-shaped track 213 provided on the outer template 201. During the installation process, ensure that the V-shaped groove is aligned with the V-shaped track 213 so that they can fit closely and achieve a stable guiding effect.

[0041] In this embodiment, the outer template 201 can be easily moved on the first translation guide rail 210 by setting the casters 212, thereby achieving fast and flexible movement, greatly shortening the construction period, and improving construction efficiency. Through the cooperation of the V-groove and the V-track 213, the first running mechanism 209 provides more stable support and guidance for the outer template 201, effectively reducing the shaking and deviation of the template during movement, and improving the accuracy and safety of construction. The first running mechanism 209 adopts a modular design and can be flexibly adjusted according to different construction requirements and template sizes, so that the running mechanism can be applied to various integrated pipe corridor construction scenarios and has a wide range of applicability.

[0042] like Fig.13 As shown, in a preferred embodiment, a demolding mechanism 228 is provided on the first running mechanism 209, and the demolding mechanism 228 includes a sliding support 229, and a crank 230 is rotatably connected to the sliding support 229. The crank 230 is threadedly connected to the first translation guide rail 210. Rotating the crank 230 drives the first translation guide rail 210 to slide on the sliding support 229 to adjust the position of the outer template 201.

[0043] Before pouring, the construction personnel drive the first translation guide rail 210 to slide on the sliding support 229 by turning the crank 230. Due to the threaded connection between the crank 230 and the first translation guide rail 210, the rotation of the crank 230 can accurately control the moving distance and direction of the first translation guide rail 210. In this way, the construction personnel can move the outer template 201 to a preset position to form a mold cavity with the inner template 106, and prepare for the pouring work.

[0044] After the pouring is completed and the concrete solidifies, the construction personnel use the demoulding mechanism 228 to perform the demoulding operation again. By turning the crank 230, the first translation guide rail 210 is driven to drive the outer template 201 away from the pouring wall. Due to the stability and accuracy of the threaded connection, the outer template 201 can be moved smoothly and accurately to achieve the demoulding process.

[0045] In this embodiment, the demoulding mechanism 228 is provided to make the movement of the outer template 201 simple and convenient. The construction personnel only need to turn the crank 230 to complete the movement and positioning of the template without complicated manual operations. The fast and precise movement function of the demoulding mechanism 228 greatly shortens the construction period and improves the construction efficiency. Before pouring, the construction personnel can quickly position the template; after pouring, the construction personnel can quickly demould the template, which improves the construction efficiency. Through the threaded connection between the crank 230 and the first translation guide rail 210, the construction personnel can accurately control the movement distance and direction of the outer template 201 to achieve precise positioning, which helps to ensure the precise fit between the outer template 201 and the inner template 106 and improve the molding quality of the model cavity.

[0046] In actual application, the driving mode of the demoulding mechanism 228 can be set according to the construction requirements to improve the construction efficiency and the convenience of operation, such as using a motor to drive the crank 230 to rotate, or using a hydraulic cylinder to drive the outer template 201 to move.

[0047] When the crank 230 is driven to rotate by the motor, a motor is first installed near the sliding support 229, and the power of the motor is transmitted to the crank 230 through a transmission device, such as a gear, a belt, etc., to ensure that the connection between the transmission device and the crank 230 is stable and reliable. Before and after pouring, the motor is started to drive the crank 230 to rotate, thereby driving the movement of the first translation guide rail 210 and the outer template 201. By using the motor to drive the crank 230 to rotate, the automatic operation of the demoulding mechanism 228 is realized. The construction personnel only need to control the motor to automatically complete the movement and positioning of the template. The motor drive method can respond quickly and realize the rapid movement of the template. Compared with manual operation, the motor drive can greatly improve the construction efficiency and shorten the construction period. The tediousness of manual operation is reduced, and the speed and direction of rotation of the motor can be accurately controlled, thereby realizing the precise control of the template movement speed and distance, which helps to improve the accuracy of template positioning and construction efficiency.

[0048] When the outer formwork 201 is driven to move by the hydraulic cylinder, the hydraulic cylinder is installed between the outer formwork 201 and the sliding support 229, and the telescopic rod of the hydraulic cylinder is firmly connected to the outer formwork 201 through the connecting piece to ensure that the telescopic rod of the hydraulic cylinder can move synchronously with the outer formwork 201. Before and after pouring, the movement and positioning of the outer formwork 201 are driven by controlling the telescopic movement of the hydraulic cylinder. The hydraulic cylinder has high thrust and stability and can easily drive the movement of the outer formwork 201. Even in a construction environment with greater resistance, the hydraulic cylinder can maintain a smooth telescopic movement to ensure the stability of the movement of the outer formwork 201.

[0049] like Fig.11 and Fig.12 As shown, in a preferred embodiment, the second running mechanism 214 includes a connecting frame 215 connected to the top of the outer template 201, and a roller bracket 221 is movably provided at the first end of the connecting frame 215. A first adjustment hole is provided on the connecting frame 215, and a second adjustment hole is provided on the roller bracket 221. The first adjustment hole or the second adjustment hole is a waist-shaped hole, and an adjustment fastener is provided through the first adjustment hole and the second adjustment hole. The roller bracket 221 includes a cross bar and vertical bars arranged at both ends of the bottom of the cross bar, and roller seats 221 are arranged opposite to each other on opposite sides of the two vertical bars. 22. The roller seat 222 and the roller bracket 221 are connected by bolts, and a spring 223 is sleeved between the roller seat 222 and the roller bracket 221. A vertically arranged clamping roller 224 is rotatably connected to the roller seat 222. A second translation guide rail 225 is arranged between the two clamping rollers 224. A first connecting seat 226 is arranged at the bottom of the second translation guide rail 225. An embedded rod 227 is arranged at the bottom of the first connecting seat 226. The embedded rod 227 is connected to the steel cage in the model cavity, and the embedded rod 227 and the steel cage can be connected by welding or binding.

[0050] In the construction preparation stage, firstly, the roller bracket 221 is installed at the first end of the connecting frame 215, and the clamping roller 224 is installed on the roller seat 222 through the rotating shaft, and the roller seat 222 is connected to the vertical rod by bolts. A spring 223 is arranged on the bolt outer sleeve between the roller seat 222 and the vertical rod, and the spring 223 pushes the roller seat 222, so that the clamping roller 224 always keeps in contact with the first translation guide rail 210, ensuring the stability and reliability of the clamping roller 224 during the movement, and then the connecting frame 215 is connected to the top of the outer template 201. The first translation guide rail 210 is arranged between the clamping rollers 224, and the first translation guide rail 210 provides precise guidance for the movement of the outer template 201. A connection seat 226 is provided at the bottom of the first translation guide rail 210. Before pouring, the embedded rod 227 at the bottom of the connection seat 226 is connected to the steel cage in the mold cavity. The connection between the embedded rod 227 and the steel cage can be achieved by welding or binding. The specific method is selected according to the actual situation on site and engineering requirements. After pouring, the embedded rod 227 is stably connected to the solidified concrete to ensure the stability of the first translation guide rail 210, thereby ensuring that the outer template 201 can move stably.

[0051] During movement, the outer template 201 can be moved by the first running mechanism 209. At this time, the two clamping rollers 224 are clamped on both sides of the first translation guide rail 210, and move forward steadily along the first translation guide rail 210, driving the outer template 201 to move to the next casting position.

[0052] In this embodiment, the first running mechanism 209 improves the stability of the outer template 201 during movement. The use of the clamping roller 224 and the first translation guide rail 210 ensures the stability and accuracy of the template movement, and effectively reduces the shaking and deviation of the outer template 201 during movement.

[0053] like Fig.11 and Fig.12 As shown, in a preferred embodiment, a connecting sleeve 216 is provided at the second end of the connecting frame 215, a fixing rod 218 is provided on the outer template 201, the connecting sleeve 216 is movably sleeved on the fixing rod 218, a first limiting block 219 is provided on the fixing rod 218 below the connecting sleeve 216, a first limiting hole is provided on the first limiting block 219, a second limiting block 217 is provided on the connecting sleeve 216, a second limiting hole is provided on the second limiting block 217, and limiting fasteners 220 are provided in the first limiting hole and the second limiting hole.

[0054] During installation, firstly, a first limiting hole is opened on the first limiting block 219, and then the first limiting block 219 is installed on the outer side of the fixing rod 218. The first limiting block 219 is fixed on the fixing rod 218 by welding to ensure the stability of its connection. Then, according to the structure and force requirements of the outer template 201, the installation rod is fixed at an appropriate position, and the connection between the installation rod and the outer template 201 is bolted or welded to ensure that the connection between the installation rod and the outer template 201 is firm and reliable. Subsequently, the second end of the connecting frame 215 is aligned with the fixing rod 218, and the connecting sleeve 216 is sleeved on the fixing rod 218, and the connecting frame 215 can rotate freely around the fixing rod 218. The second limiting block 217 is welded on the connecting sleeve 216, and a second limiting hole is set on the second limiting block 217. The size and position of the second limiting hole match the first limiting hole, ensuring that the subsequent limiting fastener 220 can be smoothly inserted and play a limiting role.

[0055] During pouring, the connecting frame 215 is away from the pouring area to prevent the concrete slurry from adhering to the connecting frame 215, so as to ensure that the connecting frame 215 can rotate normally. After pouring, the connecting frame 215 is rotated so that the clamping roller 224 moves to the top of the first translation guide rail 210, and moves downward to clamp the clamping roller 224 to both sides of the first translation guide rail 210. At this time, the first limiting hole is aligned with the second limiting hole, and the limiting fastener 220 is inserted into the first limiting hole and the second limiting hole to limit the relative position of the connecting frame 215 and the fixing rod 218. The limiting fastener 220 can be a limiting bolt or a limiting pin. The selection of the limiting fastener 220 is determined according to actual needs and the construction environment to ensure that it has sufficient strength to withstand various loads generated during the movement of the template.

[0056] In this embodiment, by setting the connecting sleeve 216, the fixing rod 218 and the limiting structure, the connection between the connecting frame 215 and the outer template 201 becomes very stable, which can ensure the stability of the outer template 201 during the movement and reduce the construction problems caused by loose connection. The connecting sleeve 216 and the fixing rod 218 make the connection process simple and fast. The construction personnel only need to put the connecting sleeve 216 on the fixing rod 218 and fix it with the limiting fastener 220. The installation steps are simple. Since the cooperation between the connecting sleeve 216 and the fixing rod 218 has a certain degree of adjustability, the position of the connecting frame 215 can be appropriately adjusted according to actual needs. The stable connection structure not only ensures the stability of the template, but also improves the safety of construction.

[0057] like Figure 7 , Figure 8 and Fig.14As shown, in a preferred embodiment, the outer template 201 includes a transverse back rib 202, a frame 203 is provided on the first side of the transverse back rib 202, a model plate 204 is provided on the first side of the frame 203, and a demoulding portion is provided on the model surface of the model plate 204.

[0058] The skeleton 203 includes horizontal rods, vertical rods and frames. The skeleton 203 is mainly used to enhance the overall strength of the outer formwork 201 and provide support for the transverse back ribs 202 and the model plate 204. The transverse back ribs 202 are used to carry the tension screws to ensure the structural strength of the outer formwork 201. The tension screws connect the outer formwork 201 and the inner formwork 106 to ensure the structural stability of the casting cavity. A demoulding part is set on the model surface of the model plate 204. The demoulding part is determined according to the specific construction environment and the formwork material to ensure that the outer formwork 201 can be smoothly separated from the concrete during the demoulding process. The demoulding part includes applying a demoulding agent on the model plate 204 or setting a fiberglass board, etc.

[0059] In this embodiment, through the support of the transverse back ribs 202 and the skeleton 203, the outer template 201 has a stable structure, can withstand various loads during the construction process, and ensure the molding quality of the pipe gallery. At the same time, the setting of the demoulding part makes the demoulding process smoother, reducing the demoulding time and labor costs. The demoulding part can ensure the molding effect of the pipe gallery, making the pipe gallery smooth and flat, reducing flaws and defects, and reducing finishing after pouring. The demoulding part can protect the model plate 204, which can be reused many times after proper care and maintenance, reducing construction costs.

[0060] like Figure 7 , Figure 8 and Fig.14 As shown, in a preferred embodiment, a third connecting plate 205 and a fourth connecting plate 206 are respectively provided on both sides of the skeleton 203, a third connecting plate 205 is provided with a third connecting hole 207, and a fourth connecting hole 208 is provided on the fourth connecting plate 206, the third connecting hole 207 corresponds to the fourth connecting hole 208 one by one, and a quick release part 111 is provided in the third connecting hole 207 of one skeleton 203 and the fourth connecting hole 208 of the adjacent skeleton 203, the quick release part 111 is used to connect two adjacent skeletons 203, and the quick release part 111 is an aluminum film plate pin or buckle, wherein the aluminum film plate pin includes a pin and a pin sheet.

[0061] During installation, two adjacent skeletons 203 are spliced ​​together, the third connecting plate 205 of one skeleton 203 is in contact with the fourth connecting plate 206 of the other skeleton 203, and the third connecting hole 207 corresponds to the fourth connecting hole 208. Pass the pin through the corresponding third connecting hole 207 and the fourth connecting hole 208, and then insert the pin into the pin. Use a hammer or other tool to nail the pin tightly so that the third connecting plate 205 and the fourth connecting plate 206 are tightly connected together, ensuring that all quick-release parts 111 are tightened and the connection is firm and reliable, ensuring that all joints are tight and seamless to prevent leakage. At the end of the outer template 201 trolley, the third connecting plate 205 and the fourth connecting plate 206 are connected to the end template through the third connecting hole 207 and the fourth connecting hole 208 respectively.

[0062] In this embodiment, by using the quick release part 111 to connect the third connecting plate 205 and the fourth connecting plate 206, the operator can quickly complete the connection and disassembly work, which greatly improves the construction efficiency. The quick release part 111 makes the connection process simple and quick, reduces unnecessary operation steps and time consumption, and reduces manpower input and working hours. The third connecting plate 205 and the fourth connecting plate 206 are tightly connected together by the aluminum film plate pins to form a stable connection structure, which not only ensures the stability of the outer template 201 during the pouring process, but also effectively prevents the slurry from leaking from the joints. In addition, the workload of later finishing and cleaning is reduced, further reducing the construction cost.

[0063] like Figure 2 and Fig.12 As shown, in a preferred embodiment, the inner trolley template 100 includes a trolley frame 101, a top template 102 is arranged on the top of the trolley frame 101, corner templates 103 are hinged on both sides of the top template 102, side templates 106 are arranged on both sides of the trolley frame 101, and a quick release part 111 is arranged between the top of the side template 106 and the bottom of the corner template 103 to connect the two, and the contact surface of the side template 106 and the corner template 103 is sealed and abutted. The top template 102, the side template 106 and the outer template 201 are similar in structure.

[0064] Before construction, first install the top formwork 102 on the trolley frame 101, connect the corner formwork 103 to the top formwork 102 through a hinge mechanism, and install the side formwork 106 on both sides of the trolley frame 101. Move the formwork trolley to a predetermined position, adjust the positions of the top formwork 102 and the side formwork 106 according to the casting requirements, and adjust the corner formwork 103 and the side formwork 106 to form a suitable joint. Use the quick-release parts 111 to connect the side formwork 106 to the corner formwork 103. Check all joints to ensure that the contact surfaces of the side formwork 106 and the corner formwork 103 are sealed and abutted to prevent slurry leakage during the casting process. Start casting construction, and after the concrete solidifies, remove the quick-release parts 111, quickly disassemble the side formwork 106 and the corner formwork 103, and then demold the formwork trolley.

[0065] During the disassembly process of the traditional formwork trolley, the disassembly process is cumbersome and time-consuming because of the use of fasteners such as bolts for connection. The inner trolley template 100 uses a quick-release part 111 to connect the side template 106 and the corner template 103, making the disassembly process simple and fast. The convenience and stability of the quick-release part 111 allow the operator to quickly lock and release the template, greatly shortening the disassembly time. At the same time, due to the simplification of the disassembly process, 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.

[0066] The joint between the top formwork 102 and the side formwork 106 of the formwork trolley is a key part prone to slurry leakage. The inner trolley formwork 100 achieves a sealed contact between the contact surface of the side formwork 106 and the corner formwork 103 to ensure the tightness of the joint and effectively prevent slurry from leaking from the joint during the pouring process. It 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.

[0067] like Fig.12 As shown, in a preferred embodiment, a first connecting plate 104 is provided at the bottom of the corner template 103, a plurality of first connecting holes 105 are provided on the first connecting plate 104, a second connecting plate 107 in contact with the first connecting plate 104 is provided on the top of the side template 106, a plurality of second connecting holes 108 corresponding to the first connecting holes 105 are provided on the second connecting plate 107, and a quick release member 111 passes through the first connecting holes 105 and the second connecting holes 108 to connect the first connecting plate 104 and the second connecting plate 107;

[0068] A receiving groove 109 is disposed on the top of the side template 106 . A sealing member 110 is disposed in the receiving groove 109 . The height of the sealing member 110 is not less than the depth of the receiving groove 109 .

[0069] During installation, prepare a corresponding number of aluminum film pins, including pins and pin pieces. Align the bottom of the corner formwork 103 with the top of the side formwork 106 so that the first connecting plate 104 is in close contact with the second connecting plate 107, and the first connecting hole 105 corresponds to the second connecting hole 108. Pass the pin through the corresponding first connecting hole 105 and the second connecting hole 108, and then insert the pin piece into the pin. And use a hammer or other tool to nail the pin piece so that the first connecting plate 104 and the second connecting plate 107 are tightly connected together, ensuring that all quick-release parts 111 are tightened and the connection is firm and reliable. After completing the installation of the quick-release parts 111, carefully check the connection between the corner formwork 103 and the side formwork 106 to ensure that all connections are tight and seamless, and there is no risk of leakage.

[0070] By using the quick-release parts 111 to connect the corner formwork 103 and the side formwork 106, the operator can quickly complete the connection and disassembly work, greatly improving the construction efficiency. The quick-release parts 111 make the connection process simple and quick, reduce unnecessary operating steps and time consumption, and reduce manpower input and working hours. The first connecting plate 104 and the second connecting plate 107 are tightly connected together through 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. In addition, due to the reduction of the workload of later finishing and cleaning, the construction cost is further reduced. By using the quick-release parts 111 to connect the corner formwork 103 and the side formwork 106, the formwork trolley can be more flexibly adapted to different construction environments and needs. The versatility and interchangeability of the quick-release parts 111 make it easy to modify and upgrade the formwork trolley, improving its use value and applicability.

[0071] By setting a receiving groove 109 on the top of the side formwork 106 and installing a seal 110, the sealing of the contact surface between the corner formwork 103 and the side formwork 106 is improved. The seal 110 can fill the tiny gap between the two to prevent the slurry from leaking from the joints during the pouring process. Due to the presence of the seal 110, 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, construction workers can focus more on the pouring work itself, improving construction efficiency. The seal 110 is a rubber waterstop. According to the size and shape of the receiving groove 109, a suitable rubber waterstop is selected as the seal 110. Ensure that the width, length and thickness of the rubber waterstop meet the sealing requirements.

[0072] like Figure 3 and Figure 4As shown, in a preferred embodiment, a walking mechanism 112 is provided at the bottom of the trolley frame 101, and the walking mechanism 112 includes a hydraulic motor 113, and the hydraulic motor 113 is transmission-connected to a driving wheel 114, and the trolley frame 101 is rotationally connected to a driven wheel 115 on one side of the driving wheel 114, and a track 116 is provided below the driving wheel 114 and the driven wheel 115.

[0073] When moving the inner trolley template 100, first start the hydraulic motor 113, which converts hydraulic energy into mechanical energy and drives the driving wheel 114 to start rotating through the transmission device. At the same time, the driven wheel 115 rotates along with the driving wheel 114, and the two jointly support and drive the trolley frame 101 to move. As the driving wheel 114 rotates, the entire trolley frame 101 moves forward smoothly along the preset track 116. The operator can control the speed and direction of the trolley frame 101 by controlling the rotation speed and direction of the hydraulic motor 113. The walking mechanism 112 not only improves the construction efficiency, but also enables the template trolley to reach the designated position quickly and accurately.

[0074] like Figure 5 As shown, in a preferred embodiment, a travel limiting mechanism 117 is provided at the bottom of the trolley frame 101, and the travel limiting mechanism 117 includes a cross beam 118, and a sliding frame 119 is slidably provided under the cross beam 118, and a sliding rod 120 and a bidirectional screw 121 are provided on the sliding frame 119, and the bidirectional screw 121 is provided with two sections of threads with different rotation directions, and two sliding plates 122 are slidably provided on the sliding rod 120, and the two sliding plates 122 are respectively screwed with the two sections of threads of the bidirectional screw 121, and pulleys 123 are rotatably provided on the opposite sides of the two sliding plates 122. Rotating the bidirectional screw 121 drives the two pulleys 123 to approach each other and engage with the track 116 or move away from each other and separate from the track 116.

[0075] When the trolley frame 101 needs to be moved, the operator will rotate the bidirectional screw 121 using tools such as a wrench, or drive the bidirectional screw 121 by setting a hydraulic drive motor. The two sliding plates 122 will approach each other, driving the pulley 123 to engage with the track 116, which can effectively prevent the driving wheel 114 or the driven wheel 115 from accidentally derailing during the movement, thereby ensuring the stability and safety of the trolley frame 101.

[0076] When the top template 102 needs to be raised or lowered, the pulleys 123 of the travel limiting mechanism 117 are driven to move away from each other, so that the pulleys 123 are separated from the track 116, and the trolley frame 101 will not be restricted by the track 116 to affect the raising or lowering of the top template 102. The operator can adjust the height of the top template 102 as needed to perform construction operations such as pouring.

[0077] In this embodiment, the travel limiting mechanism 117 can effectively prevent the trolley frame 101 from derailing due to external force or improper operation during movement, greatly improving the safety of construction. The travel limiting mechanism 117 can not only realize the positioning and limiting of the trolley frame 101, but also can be separated from the track 116 when necessary, so that the top template 102 can be freely raised and lowered, meeting the needs of different construction scenes and enhancing the flexibility of construction.

[0078] like Figure 6 As shown, in a preferred embodiment, legs 124 are respectively provided on both sides of the bottom of the trolley frame 101, and the legs 124 include a lifting hydraulic cylinder 125. Each lifting hydraulic cylinder 125 is provided with a hydraulic lock 126. The piston rod of the lifting hydraulic cylinder 125 is vertically downward, and a pad 127 is provided at the bottom of the piston rod of the lifting hydraulic cylinder 125.

[0079] Before the trolley frame 101 moves to the designated position, the legs 124 are in a retracted state, the piston rod of the lifting hydraulic cylinder 125 is fully retracted, and the pad 127 does not contact the casting bottom plate. When the walking mechanism 112 moves the trolley frame 101 to the designated position, the walking limit mechanism 117 releases the track 116, and the operator controls the lifting hydraulic cylinder 125 to start, so that the piston rod extends vertically downward. The telescopic action of the lifting hydraulic cylinder 125 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 127 contacts the casting bottom plate to provide support for the trolley frame 101. By controlling the telescopic movement of the lifting hydraulic cylinder 125, the distance between the pad 127 and the casting bottom plate can be adjusted, and then the overall height of the trolley frame 101 can be adjusted, thereby achieving precise control of the height of the top template 102. After the support legs 124 are adjusted to a suitable position, the hydraulic lock 126 will be activated to ensure that the piston rod of the lifting hydraulic cylinder 125 is fixed in position, thereby preventing the template from falling due to pressure relief of the lifting hydraulic cylinder 125 during pouring or other construction processes.

[0080] Through the precise control of the lifting hydraulic cylinder 125, the height of the top template 102 can be adjusted to meet the requirements of high-precision construction. The design of the legs 124 provides stable support for the trolley frame 101, enhancing its stability during the construction process, especially when performing heavy-load operations such as pouring, which can effectively prevent the trolley frame 101 from sinking or shaking. The addition of the hydraulic lock 126 ensures the position stability of the legs 124 after being adjusted into place, preventing the lifting hydraulic cylinder 125 from depressurizing, thereby improving the safety of construction.

[0081] like Figure 2 As shown, in a preferred embodiment, a translation mechanism 128 is connected between the side template 106 and the trolley frame 101 , and the translation mechanism 128 includes a translation hydraulic cylinder 129 arranged at the upper part of the trolley frame 101 and a positioning hydraulic cylinder 130 at the lower part.

[0082] Before the pouring operation begins, the operator moves the side template 106 to a predetermined position by controlling the translation mechanism 128. When the side template 106 moves to the correct position, the concrete pouring operation begins. The model surface of the side template 106 is also provided with a demoulding portion, which helps to smoothly separate the template from the concrete after the pouring is completed. After the concrete solidifies, the side template 106 is moved toward the trolley frame 101 by controlling the translation mechanism 128 to achieve demoulding and prepare for the next pouring operation. Controlling the movement of the side template 106 by the translation mechanism 128 greatly simplifies the installation and disassembly process of the template and improves the construction efficiency.

[0083] 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.
