[0002] In the construction of intelligent beam yards for precast T-beams for highway bridges, formwork demolding is required after the T-beams are poured. Traditional end-formwork demolding methods rely primarily on manual operation, which presents several problems: First, operators must climb to the formwork location for manual removal, which is not only labor-intensive and inefficient but also poses significant safety hazards due to working at heights.

Detailed Implementation

[0047] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0048] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0049] In existing technologies, the demolding process of end formwork during the construction of precast T-beams for highway bridges typically relies on manual operation. Operators must climb to the formwork location, manually remove the fixing bolts, and pry open the end formwork, posing safety hazards such as falls from heights and formwork slippage. Traditional methods are limited by the efficiency of manual handling, making it difficult to quickly disassemble and assemble large-sized end formwork, especially in mass production scenarios where repeated disassembly and assembly operations extend the construction cycle.

[0050] To address these issues, researchers discovered that the core challenge of manual operation lies in the lack of mechanized force application devices and high-altitude positioning aids. By analyzing the stress characteristics of the template, they proposed combining a hydraulic drive system with a gantry crane, using hydraulic cylinders to provide stable thrust instead of manual prying. Simultaneously, a detachable attachment structure enables rapid device positioning, avoiding repeated adjustments to the installation location.

[0051] Therefore, as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this application proposes a hydraulic end mold demolding device for precast T-beams, comprising a side mold assembly 100, an end mold assembly 200 detachably disposed at the side end of the side mold assembly 100, a gantry crane frame 300, and a hydraulic drive assembly 400. The front end of the gantry crane frame 300 is detachably connected to the upper end of the side mold assembly 100, and the hydraulic drive assembly 400 is mounted on it; the telescopic end of the hydraulic drive assembly 400 is detachably connected to the end mold assembly 200 to disengage the end mold assembly 200 from the mold closing position.

[0052] The side formwork assembly 100 refers to the hydraulic formwork structure that supports the concrete pouring and forming of the T-beam. Specifically, it can be implemented using a steel formwork with angle steel frames 102, and its ends are equipped with hook-up interfaces for connecting to the overhead crane frame 300. The end formwork assembly 200 refers to the formwork that seals the end profile of the T-beam. Specifically, it can be implemented using a combination structure of a T-shaped mounting plate and the end formwork body, and is connected to the overhead crane via a first lifting lug. The overhead crane frame 300 refers to the frame that provides high-altitude positioning and hydraulic system support. Specifically, it can be implemented using a trapezoidal steel structure welded from square tubing, and is rigidly connected to the side formwork assembly via hook-up brackets. The hydraulic drive assembly 400 refers to the device that provides demolding power. Specifically, it can be implemented using a combination of multiple hydraulic cylinders and an oil pump, transmitting thrust through a hinged connection between the telescopic end and the end formwork assembly.

[0053] Specifically, after the gantry crane frame 300 is hoisted to the end of the side formwork assembly 100 using external gantry crane equipment, its front-end mounting bracket forms a detachable connection with the end formwork bracket of the side formwork assembly 100, ensuring the stability of the frame. After the hydraulic pump is started, the hydraulic cylinder pushes the end formwork assembly 200 to move in the demolding direction, transmitting linear thrust through the hinged frame to detach the end formwork from the concrete surface. During demolding, the gantry crane frame 300 bears the reaction force of the hydraulic cylinder, preventing the side formwork assembly from deforming under stress. After demolding is completed, the gantry crane equipment can directly lift the end formwork assembly 200 away from the work area.

[0054] Compared to existing technologies, traditional manual demolding requires multiple people to work together to remove bolts and pry the formwork, resulting in low coordination efficiency and uneven force application that can damage the formwork. This solution provides controllable thrust through a hydraulic system, eliminating deviations caused by manual force application; the detachable rigid connection between the overhead crane frame 300 and the side formwork assembly 100 ensures accurate demolding trajectory and avoids lateral displacement of the formwork; the detachable connection structure simplifies the installation process, reducing the time for a single demolding operation to one-fifth of that of traditional methods.

[0055] Through the above technical solutions, this application achieves two advantages: firstly, hydraulic drive replaces manual prying, eliminating the safety hazards of manual operation at height; secondly, the connection between the overhead crane frame 300 and the side mold assembly 100 forms a stable force-bearing system, preventing the mold from shaking during demolding; and thirdly, the detachable connection structure between the overhead crane frame 300 and the side mold assembly 100 enables the device to have a rapid transfer capability, adapting to the needs of continuous multi-station operation.

[0056] In some of these embodiments, such as Figure 6 and Figure 7As shown, this application further proposes that angle steel frames 102 are respectively provided at the ends of the left and right side mold bodies 101 of the side mold assembly 100, and end mold hangers 103 are respectively provided at the upper ends of the two angle steel frames 102. The angle steel frame 102 refers to a frame structure formed by welding angle steel, specifically, L-shaped equilateral angle steel can be connected to the ends of the side mold bodies 101 through welding to form a rigid support structure. The end mold hanger 103 refers to a connecting component provided at the upper end of the angle steel frame 102, specifically, a steel plate with a U-shaped groove can be welded to the top of the angle steel frame for plug-in engagement with the hanging bracket 320 of the overhead crane frame 300.

[0057] Specifically, by welding the end mold bracket 103 to the upper end of the angle steel frame 102, the opening direction of its U-shaped groove is consistent with the movement trajectory of the hanging rod 321 of the gantry crane frame 300. During the hoisting process, the hanging rod 321 can slide into the predetermined position along the U-shaped groove to achieve rapid positioning.

[0058] In some of these embodiments, such as Figure 8 , Figure 9 and Figure 10 As shown, this application further proposes an end mold assembly 200 including an end mold mounting plate 210, an end mold body 220, and a hydraulic cylinder hinge frame 230. The end mold mounting plate 210 has a T-shaped cross-section, and its front side wall is provided with an end mold body 220 that mates with the end opening of the side mold assembly 100. First lifting lugs 211 are respectively provided at both ends of the top. There are at least two hydraulic cylinder hinge frames 230, which are respectively spaced at the upper and lower ends of the rear side wall of the end mold mounting plate 210, and their rear ends are hinged to the telescopic ends of the corresponding hydraulic cylinders 410 on the hydraulic drive assembly 400.

[0059] The T-shaped structure refers to the T-shaped cross-section of the end formwork mounting plate 210, which can be formed by welding or casting steel plates to create a structure with a vertical web and horizontal flanges. This structure increases the bending stiffness by increasing the moment of inertia of the cross section, preventing deformation caused by the lateral pressure of concrete. The first lifting lug 411 refers to the metal lifting ring set on the top of the end formwork mounting plate, which can be made by bending and welding round steel to form symmetrically distributed lifting points to balance the lifting force applied by the gantry crane. The hydraulic cylinder articulation frame 230 refers to the metal bracket connecting the hydraulic cylinder 410 and the end formwork mounting plate 210, which can be made by welding channel steel or angle steel into a triangular structure. Its front end is welded to the end formwork mounting plate 210, and its rear end can be connected to the telescopic end of the hydraulic cylinder 410 through a pin and a ball joint to realize power transmission. The hydraulic cylinder 410 and the hydraulic cylinder articulation frame 230 can be quickly connected by the pin, or the telescopic end of the hydraulic cylinder 410 can be separated from the hydraulic cylinder articulation frame 230 for quick disassembly.

[0060] Specifically, the end mold body 220 on the front side wall of the T-shaped end mold mounting plate 210 interlocks with the end opening of the side mold assembly 100. The horizontal flange of the end mold mounting plate 210 covers the outer surface of the side mold assembly 100, forming a double positioning constraint. The symmetrically arranged first lifting lugs 411 enable the gantry crane to achieve force couple balance when lifting the end mold assembly, avoiding rotational torque caused by a single lifting point. The hydraulic cylinder hinge frames 230 arranged at the upper and lower ends respectively bear the hydraulic driving force in the vertical direction, ensuring that the end mold body 220 maintains a vertical movement trajectory when it is translated and removed, eliminating the offset caused by the lateral resistance generated by concrete adhesion.

[0061] Through the above technical solution, this application achieves a stable connection between the end mold assembly 200 and the hydraulic drive assembly 400, avoiding structural displacement caused by uneven force during demolding. The T-shaped end mold mounting plate 210 and the end mold body 220, along with the side mold assembly 100, ensure installation and positioning accuracy. The hydraulic cylinder hinge frame 230 arranged at the upper and lower ends effectively offsets the demolding resistance through spatial force decomposition, allowing the end mold body 220 to move smoothly along a preset trajectory, solving the technical problems of low efficiency and poor safety in traditional manual demolding.

[0062] In addition, such as Figure 9 and Figure 10 As shown, this application further proposes that the end mold assembly 200 also includes a reinforcing rod 240, which is a square tube structure, with its upper and lower ends fixedly connected to each hydraulic cylinder hinge frame 230. The reinforcing rod 240 refers to a longitudinal support member connecting multiple hydraulic cylinder hinge frames 230, and can be fixed to the hydraulic cylinder hinge frames 230 by welding or bolting to form a rigid connection frame. The square tube structure refers to a hollow tube with a rectangular cross-section, specifically formed by bending cold-rolled steel sheet. Its cross-sectional shape is symmetrical, providing uniform bending and torsional resistance.

[0063] Specifically, the upper and lower ends of the reinforcing rod 240 are fixedly connected to multiple hydraulic cylinder hinge frames 230 distributed on the rear side wall of the end mold mounting plate 210, forming a three-dimensional support network. During hydraulic drive, the reinforcing rod 240, with its square tube structure, offsets the lateral loads from the different hinge frames 230 through its bending rigidity, while simultaneously constraining the relative displacement of each hinge frame during telescopic movement through its torsional resistance. This connection method couples the force paths of the multiple hinge frames 230, transforming localized concentrated loads into distributed loads along the length of the reinforcing rod 240, thereby avoiding deformation of the end mold body 220 caused by single-point stress concentration, and consequently avoiding the risk of equipment jamming or connector breakage due to structural instability.

[0064] In some of these embodiments, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , 11 and Figure 12 As shown, this application further proposes a gantry crane frame 300 including a frame body 310, a hanging bracket 320, and a support bracket 330. The frame body 310 is a steel structure frame with an isosceles trapezoidal cross-section, welded from square tubing. Hanging brackets 320 are respectively installed at the left and right ends of the upper front side, and support brackets 330 are respectively installed at the left and right ends of the lower front side. The front ends of the two hanging brackets 320 are respectively connected to the end mold mounting base 103 at the end of the side mold assembly 100, and the front ends of the two support brackets 330 are abutted against the lower end of the side mold assembly 100.

[0065] The frame body 310 refers to the main frame structure that supports the hydraulic drive assembly 400. Specifically, it can be implemented using a welded square tube structure with an isosceles trapezoidal cross-section. The isosceles trapezoidal structure enhances lateral bending resistance through symmetrical distribution. The mounting bracket 320 refers to the connecting component located on the upper front side of the frame body 310. Specifically, it can be implemented using a bracket structure with mounting rods 321, forming a suspended fixation through mechanical engagement with the end mold mounting base 103. The support bracket 330 refers to the load-bearing component located on the lower front side of the frame. Specifically, it can be implemented using a vertical support rod structure, forming a bottom support point through contact with the lower end face of the side mold assembly 100.

[0066] Specifically, the isosceles trapezoidal frame body 310 creates a stable mechanical distribution through the difference in width between its front and rear sides, allowing stress to be evenly transferred to the side mounting brackets 320 when subjected to hydraulic drive loads. The connection between the mounting brackets 320 and the upper mold mounting base 103 of the side mold forms an upper constraint, while the contact between the support bracket 330 and the lower end of the side mold forms a lower constraint; together, they constitute a two-point fixing system. The isosceles trapezoidal frame body 310, constructed of welded square tubing, reduces overall weight through a hollow section design while ensuring structural rigidity, meeting the weight requirements of high-altitude hoisting operations.

[0067] Through the above technical solutions, this application effectively solves the structural instability problem when the gantry crane frame 300 is connected to the side formwork assembly 100. The upper and lower dual-point constraint mechanism can simultaneously resist the tensile and compressive loads generated by the hydraulic drive, preventing the frame from shifting or overturning during operation. The symmetrical structure of the isosceles trapezoidal frame body 310 enhances lateral stability and avoids connection failure caused by lateral displacement. The square tube welding process reduces the weight of the equipment while ensuring structural strength, enabling the gantry crane frame 300 to bear the working load of the hydraulic drive assembly while meeting the weight restriction requirements of high-altitude hoisting equipment.

[0068] In some of these embodiments, such as Figure 1 , Figure 2 , 11 and Figure 12 As shown, this application further proposes that a hanging rod 321 is provided at the bottom of the front end of the hanging bracket 320, and its front end is fixedly connected to the frame body 310 through an inclined connecting rod 322. The hanging rod 321 is a rigid connecting component provided at the bottom of the front end of the hanging bracket 320, which can be welded from round or square steel, and is used to form a rigid connection with the end mold mounting base 103 at the end of the side mold assembly 100, directly bearing the longitudinal tensile force during demolding. The inclined connecting rod 322 is a support component inclinedly arranged between the front end of the hanging bracket 320 and the frame body 310, which can be welded and fixed from angle steel or channel steel, and is used to form a triangular support structure between the hanging bracket 320 and the frame body 310, enhancing bending stiffness and torsional resistance.

[0069] During demolding, the tension applied by the hydraulic drive assembly 400 is transmitted to the end mold bracket 103 of the side mold assembly 100 through the hook rod 321, while the diagonal connecting rod 322 converts the horizontal component of the force into the axial pressure of the frame body 310, avoiding local stress concentration that could lead to structural deformation. The synergistic effect of both ensures that the connection between the overhead crane frame 300 and the side mold assembly 100 forms a stable rigid support system, ensuring uniform force distribution during demolding.

[0070] In some of these embodiments, such as Figure 11 and Figure 12 As shown, this application further proposes a cantilever beam mounting base 340, a horizontal cantilever beam 350, and a second lifting lug 360, all disposed on the top of the frame body 310. The front end of the cantilever beam mounting base 340 is vertically arranged towards the end mold assembly 200. The horizontal cantilever beam 350 is movably disposed within a horizontal slide rail formed by its inner cavity. Second guide slide plates 351 are respectively disposed at the bottom and top of the horizontal cantilever beam 350. Several second lifting lugs 360 are fixedly disposed at the four top corners of the frame body 100 for connecting external overhead crane equipment.

[0071] The cantilever beam mounting base 340 refers to the guide mechanism used to support the horizontal cantilever beam 350. Specifically, it can be implemented using a combination structure of a limiting frame and a guide slide plate welded to the top of the frame body 310. The limiting frame forms a slideway space, and the guide slide plate provides a sliding contact surface. The horizontal slideway refers to the channel running through the front and rear directions of the cantilever beam mounting base 340, specifically formed by two guide slide plates arranged parallel to each other, constraining the horizontal cantilever beam 350 to move only axially. The second guide slide plate 351 refers to the wear-resistant plate fixed to the upper and lower surfaces of the horizontal cantilever beam 350, specifically made of polytetrafluoroethylene composite steel plate, forming a low-friction sliding pair with the first guide slide plate 342 on the cantilever beam mounting base 340.

[0072] Specifically, when the horizontal cantilever beam 350 slides axially within the horizontal slide rail 343, the second guide slide plate 351 forms surface contact with the first guide slide plate 342 on the cantilever beam mounting base 340, eliminating lateral offset. The vertical arrangement of the front end of the cantilever beam mounting base 340 ensures that the moving axis of the horizontal cantilever beam 350 is orthogonal to the demolding direction of the end mold, guaranteeing that the line of action of the traction force always passes through the center of gravity of the end mold. A group of second lifting lugs 360 is symmetrically distributed on the top of the frame body 310, and the lifting force of the gantry crane is evenly transmitted to the frame structure of the frame body 310 through multi-point lifting, avoiding structural deformation caused by single-point force.

[0073] Specifically, such as Figure 9 and Figure 10 As shown, this application further proposes that the cantilever beam mounting base 340 is composed of a limiting frame 341 and a first guide slide plate 342 that cooperates with the second guide slide plate 351. The limiting frame 341 has an inverted U-shaped structure, and there are two of them, which are welded to the front and rear ends of the top of the frame body 310 at intervals. There are two first guide slide plates 342, which are horizontally arranged at intervals and inside the top and bottom of the left and right limiting frames 341, forming a horizontal slide 343 that runs through the front and back.

[0074] The limiting frame 341 is a support structure used to constrain the lateral displacement of the horizontal cantilever beam. It can be implemented by welding square tubes into an inverted U-shaped structure, and its front and rear spacing arrangement can form symmetrical support points. The first guide slide plate 342 is a guide component that forms a sliding fit with the second guide slide plate 351 at the bottom and top of the horizontal cantilever beam 350. It can be implemented by using a surface-polished steel plate, and its upper and lower spacing arrangement can form a clamping guide channel.

[0075] Specifically, the inverted U-shaped limiting frame 341 is welded to the top of the frame body 310 at intervals, forming two symmetrical rigid support points to limit the lateral displacement of the horizontal cantilever beam 340 during its movement. The first guide slide plate 342, spaced vertically, forms double sliding contact with the second guide slide plate 351 of the horizontal cantilever beam 350, preventing tilting of the beam through synchronous guidance from the upper and lower surfaces. The continuous horizontal slide structure ensures that the horizontal cantilever beam 350 maintains a straight trajectory during movement, avoiding jamming caused by track interruptions.

[0076] In some of these embodiments, such as Figure 11 and Figure 12As shown, this application further proposes that the overhead crane frame 300 also includes a hydraulic cylinder mounting base 370 and an oil pump mounting base 380. There are at least two hydraulic cylinder mounting bases 370, preferably two, which are vertically fixedly installed at the upper and lower ends of the front end side of the frame body 310, respectively, for mounting each hydraulic cylinder 410; the oil pump mounting base 380 is horizontally installed at the middle position of the rear end side of the frame body 310, for mounting a hydraulic oil pump 420 connected to the hydraulic cylinder 410.

[0077] The hydraulic cylinder mounting base 370 refers to the support structure that supports the hydraulic cylinder 410. Specifically, it can be achieved by welding steel plates to form a rigid connection with the frame body 410. It is vertically arranged at the upper and lower ends of the front end of the frame body 310, so that the extension and retraction thrust of the hydraulic cylinder 410 is distributed and transmitted to the frame body 310 through the upper and lower support points. The oil pump mounting base 380 refers to the base that supports the hydraulic oil pump 420. Specifically, it can be achieved by horizontally welded channel steel frame. It is set in the middle of the frame body 310, so that the center of gravity of the hydraulic oil pump 420 coincides with the load-bearing axis of the frame body 310.

[0078] Specifically, the hydraulic cylinder mounting base 370 forms dual support points at the upper and lower ends of the front end of the frame body 310. After the hydraulic cylinder 410 is installed, its extension and retraction direction remains parallel to the movement trajectory of the end mold assembly 200. The upper and lower distributed hydraulic cylinder mounting bases 370 can counteract the overturning moment when the hydraulic cylinder 410 is working, avoiding frame deformation caused by single-point support. The oil pump mounting base 380 is located in the middle of the frame body 310. This position has high structural strength and can withstand the vibration load of the hydraulic oil pump 420 during operation. At the same time, it shortens the connection distance between the hydraulic pipeline and the upper and lower hydraulic cylinders 410, reducing pressure loss.

[0079] Through the above technical solutions, this application ensures that the hydraulic drive assembly 400 maintains stable operation during demolding, the upper and lower double support structure of the hydraulic cylinder 410 avoids deformation of the frame body 310 under stress, the middle installation position of the oil pump reduces the bending loss of hydraulic pipelines, the overall layout improves the working efficiency of the hydraulic system, reduces the frequency of equipment maintenance, and ensures the safety and continuity of demolding operation.

[0080] In some of these embodiments, such as Figure 3 , Figure 4 , Figure 5 , Figure 11 and Figure 12 As shown, this application further proposes that the hydraulic drive assembly 400 consists of a hydraulic cylinder 410 and a hydraulic oil pump 420. The hydraulic cylinder 410 is detachably mounted on the corresponding hydraulic cylinder mounting seat 370 on the front end side of the gantry crane frame 300 via a fixing plate 411 at the front end. The hydraulic oil pump 420 is detachably mounted on the oil pump mounting seat 380 in the middle of the gantry crane frame 300 and is connected to each hydraulic cylinder 410 via hydraulic pipes.

[0081] Hydraulic cylinder 410 is a power actuator that provides linear thrust. It can be a double-acting hydraulic cylinder, with its front end rigidly connected to hydraulic cylinder mounting base 370 via a fixing plate 411. This converts hydraulic energy into mechanical energy to drive the displacement of the end module assembly. Fixing plate 411 is a metal plate that supports the installation of hydraulic cylinder 410. It can be a steel plate with bolt holes and is detachably fixed to hydraulic cylinder mounting base 370 via bolts, ensuring the positioning accuracy of hydraulic cylinder 410 and the overhead crane frame 300. Hydraulic pump 420 is a power source that generates hydraulic power. It can be a gear pump or piston pump, and is independently fixed to the overhead crane frame 300 via pump mounting base 380. This pump supplies high-pressure hydraulic fluid to hydraulic cylinder 410.

[0082] Specifically, the hydraulic cylinder 410 is detachably rigidly connected to the hydraulic cylinder mounting base 370 at the front end of the gantry crane frame 300 via a fixing plate 411. The symmetrical arrangement of two or more hydraulic cylinders 410 can achieve synchronous drive. The hydraulic oil pump 420 is independently installed on the oil pump mounting base 380 in the middle of the gantry crane frame 300, and forms a closed loop with each hydraulic cylinder 410 through hydraulic pipes. When the hydraulic oil pump 420 starts, pressurized oil is delivered to the rodless chamber of the hydraulic cylinder 410 through the hydraulic pipes, pushing the piston rod to extend out of the drive end mold assembly (200) for demolding; during the return stroke, the oil switches to the rod chamber to achieve retraction.

[0083] Combination Figures 1 to 5 As shown, the installation method of the precast T-beam hydraulic end mold demolding device is as follows: the gantry crane frame 300 is hoisted at high altitude using a gantry crane, and the gantry crane frame 300 is directly suspended on the end mold bracket 103 at the end of the side mold assembly 100; then the hydraulic drive assembly 400 is powered on, and the hydraulic cylinder 410 is controlled to extend and retract using a wireless remote control.

[0084] The operation mode of the precast T-beam hydraulic end mold demolding device is as follows: After the side mold assembly 100 is demolded, the gantry crane frame 300 is hung on the two end mold hanging seats 103 at the end of the side mold assembly 100 using a gantry crane. Then, the telescopic end of the hydraulic cylinder 410 is connected to the hydraulic cylinder hinge frame 230 using a pin. Then, the end hydraulic cylinder 410 is started to release the end mold assembly 200 from the side mold closing position. Finally, the gantry crane is used to lift the end mold assembly 200 to the ground to complete the demolding process.

[0085] Compared to traditional manual demolding methods, the precast T-beam hydraulic end mold demolding device provided in this application, through the cooperation of the overhead crane frame 300 and the hydraulic drive component 400 with the end mold component 200, allows the end mold component 200 to be moved as a whole and is easy to assemble and disassemble. When the next process is carried out after the casting is completed, it can be completed in a few minutes, eliminating the trouble of disassembling and assembling the formwork. This is an advantage that traditional steel formwork cannot match. Because it saves time, effort and labor, it is highly favored by construction teams and project departments.
