The liftable longitudinal truss-type crane provides strong support for the formwork, increases the stability of the formwork operation, improves the controllability of the cushion panel thickness, and makes the panel thickness uniform and convenient for demoulding. In addition, by installing a height-adjustable sliding form body and mold body, the height of the formwork can be adjusted in real time with the deflection deformation of the longitudinal truss-type crane, ensuring that the surface of the constructed cushion and panel is smooth and avoiding surface undulations.

[0004] In actual use, this solution requires the laying of additional transverse guide rails and longitudinal truss cranes in advance to provide a mobile support foundation.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1 , 2As shown in Figure 3, Example 1, a water tank type slipform machine for slope lining construction, includes a slipform platform 1, on which a walking mechanism 2 is provided, and the walking mechanism 2 is movably provided on the side formwork assembly 3. When the slipform machine is in use, a traction machine is arranged at the top of the slope, or a traction machine is arranged at the bottom of the slope and a fixed pulley is arranged at the top of the slope, so that the slipform platform is towed and moved by the rope of the traction machine. When in use, the side formwork assembly that is indispensable at the construction site is used as the moving track of the walking mechanism, and the movement of the slipform platform is realized by the cooperation of the walking mechanism and the side formwork assembly, without the need to lay additional tracks, reducing the demand for supporting equipment, improving construction efficiency, making the construction process simpler, while maintaining construction reliability, and facilitating transfer and continuous construction.

[0026] In addition, a spiral material distribution mechanism 4 is provided at the front end of the slipform platform 1, and the spiral material distribution mechanism 4 can spread the concrete material synchronously with the movement of the slipform platform 1 during construction. The slipform platform 1 is adjustable with a support frame 5, and a vibrating row assembly 6 is provided on the support frame 5. The vibrating row assembly can vibrate the paved concrete according to needs during paving concrete, thereby improving the paving quality.

[0027] When in use, the side formwork components are arranged in pairs and fixed in parallel on the slope to form two moving tracks for the walking mechanisms on both sides of the slipform platform to cooperate with. Under the traction of the tractor, the slipform platform moves from the bottom of the slope to the top of the slope along the parallel side formwork components as the construction progresses, and paving construction is achieved at the same time. Figure 5 As shown, the side formwork assembly 3 includes a lower formwork 7, a hinge 8 is provided on the outer side of the lower formwork 7, and the lower formwork 7 is connected to the upper formwork 9 through the hinge 8. The gap between the upper formwork 9 and the lower formwork 7 is used to set a waterstop 10. In the architectural design of a general larger project, since continuous pouring is not possible, the pouring of the slope surface needs to be carried out in sections. Therefore, a waterstop is set at each gap to achieve the purpose of waterproofing. In this embodiment, the waterstop is directly poured into the slope concrete, which can better meet the sealing requirements.

[0028] As a further implementation, a diagonal brace 11 is provided on the side wall of the lower template 7, and the diagonal brace can better form a connection and support with the sloped ground. Reinforcement connecting plates 25 are evenly spaced on the side walls of the upper template 9 and the lower template 7, and the reinforcement connecting plates 25 are detachably connected to the upper template 9 and the lower template 7 respectively by bolts. In this embodiment, since the waterstop is mostly made of rubber material, when the upper template is in an upright position, the reinforcement connecting plate can be fixed to the upper template and the lower template at the same time by bolts, maintaining the upright position of the upper template and preventing it from being completely pressed on the waterstop to cause damage to the waterstop.

[0029] When this embodiment is in use, the lower formwork is fixed on the slope, and the upper formwork is in an upright position. One side of the waterstop is set in the gap between the upper formwork and the lower formwork, and then the position between the upper formwork and the lower formwork is reinforced by using a reinforcing connecting plate. Then, a steel mesh is set between the lower formworks on both sides. Then, the slipform platform is lifted and pressed above the upper formwork, and the walking mechanisms on both sides are respectively coordinated with the upper formworks on both sides. The rope of the traction machine is connected to the slipform platform to pull the slipform platform upward along the slope, and at the same time, concrete materials are poured in front of the spiral distributing mechanism 4. The spiral distributing mechanism works to spread the concrete materials evenly, and then the vibrating row assembly 6 is used to vibrate the spread concrete. At the same time, as the support frame is moved and adjusted, the vibrating row assembly 6 is driven to cross the hole of the steel mesh to avoid collision between the vibrating row assembly and the steel mesh during movement.

[0030] Embodiment 2, on the basis of embodiment 1, as Figure 4 , 6 As shown, the walking mechanism 2 includes a front wheel frame 12 and a rear wheel frame 13 which are vertically slidably arranged on both sides of the slipform platform 1 in pairs. The front wheel frame 12 and the rear wheel frame 13 are connected to the slipform platform 1 through hydraulic cylinders Ⅰ14 respectively, and can slide vertically relative to the slipform platform 1 under the telescopic control of the hydraulic cylinders Ⅰ14, so that the distance and parallelism of the slipform platform relative to the top surface of the upper template can be adjusted according to the actual scene requirements, and the posture of the slipform platform can be controlled according to the actual situation. The front wheel frame 12 and the rear wheel frame 13 are respectively rotatably provided with front wheels 15 and rear wheels 16, and cooperate with the upper template 9 through the front wheels 15 and rear wheels 16. In this embodiment, the front wheel 15 is a cylindrical roller wheel, and the rear wheel 16 is a groove wheel. The width of the front wheel 15 is greater than the width of the rear wheel. In the concrete paving stage, the concrete material transported to the two ends by the spiral material distribution structure has poor flatness at the position close to the upper template. Therefore, the width of the front wheel is used to roll the uneven concrete to improve the flatness. The rear wheel is configured as a groove wheel, which can be engaged with the upper template when moving, thereby limiting the width. The grooves crushed by the rear wheel can be smoothed in the subsequent plastering process.

[0031] Embodiment 3, on the basis of embodiment 2, the slipform platform 1 is a box-type slipform platform, and the bottom of the slipform platform 1 is provided with an inclined surface parallel to the top surface of the upper side formwork 9. When in mobile mode, the inclined surface is used to contact with the concrete material, so that the laid concrete material can be smoothed and compacted as it moves, and the sliding phenomenon of the concrete material under the vibration of the vibrating row assembly can be reduced or avoided. A number of box cavities are opened inside the slipform platform 1, and the slipform platform 1 is provided with a water inlet and a drain 18 connected to the box cavity. In this embodiment, valves are provided on the water inlet and the drain. Before use and after the slipform platform is hoisted onto the side formwork assembly, tap water is poured into the box cavity through the water inlet to increase the weight of the entire slipform platform, so that it can contact with the concrete material during the sliding construction under traction and press and compact the vibrated concrete material to promote its molding.

[0032] In addition, a cantilever 19 is provided at the front end of the slipform platform 1, and the spiral material distribution mechanism 4 includes a conveying shaft 20 rotatably arranged on the cantilever 19, and the conveying shaft 20 is transmission-connected to a driving motor 21 fixedly arranged on the cantilever 19, and auger blades are symmetrically provided on both sides of the conveying shaft 20, and the conveying direction of the auger blades is toward both ends. In this embodiment, three cantilevers are provided in front of the slipform platform, and the two ends and the middle of the conveying shaft 20 are respectively rotatably matched with the three cantilevers, and the auger blades on both sides of the middle cantilever rotate in opposite directions, so that the conveying shaft can evenly convey the concrete material in the middle to both ends when it is rotated by the driving motor.

[0033] Furthermore, a pouring baffle 22 is provided on the cantilever 19 and is located behind the conveying shaft 20. In this embodiment, the pouring baffle is an arc-shaped plate. Since the construction paving surface is an inclined surface, the pouring baffle can prevent the concrete material from passing over the dragon blade from above and not being conveyed during movement. The pouring baffle can cooperate with the auger blade on the conveying shaft to make the concrete conveyed more evenly and with higher flatness.

[0034] Embodiment 4, based on embodiment 3, the support frame 5 is vertically slidably arranged on the sliding form platform 1, such as Figure 7 As shown, a hydraulic cylinder II 23 is provided between the slipform platform 1 and the support frame 5, and a vibrating row assembly 6 is fixed on the support frame 5. Specifically, the vibrating row assembly 6 includes a plurality of vertically arranged vibrating rods 24, and a plurality of vibrating rods 24 are fixed on the support frame 5 at equal intervals. In this embodiment, the vibrating rod adopts a conventional concrete vibrating rod, which can generate vibration when inserted into the concrete material, making the concrete material more compact, while discharging the internal bubbles and improving the molding quality. In this embodiment, during construction, the hydraulic cylinder II extends, driving the support frame to move downward, so that the lower end of the vibrating rod is inserted into the concrete material to achieve the vibration effect. As the slipform platform moves upward along the inclined plane, the vibrating rod will touch the pre-laid steel mesh. At this time, the hydraulic cylinder II is controlled to contract, driving the support frame and the vibrating rod to move upward, and then the vibrating rod is inserted again after passing the steel mesh for vibration.

[0035] 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, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
