[0040] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0041] The present invention provides Figure 1-Figure 15 A portable pipe gallery formwork trolley with automatic demoulding shown in the figure includes a support frame 1, wherein the support frame 1 includes a plurality of support frame units 11 arranged front to back, and the support frame 1 also includes a top connecting rod 121, a side connecting rod 131, a bottom reinforcing tie rod 14 and a bottom tie rod 15, and all the support frame units 11 are connected as a whole through the above four.

[0042] A top mold limiting rod 122 is welded on the top connecting rod 121, a top pin pre-set hole 123 is opened on the top mold limiting rod 122, and a top pin 124 is inserted in the top pin pre-set hole 123, so as to ensure that the top mold is placed in place, and a side mold limiting rod 132 is welded on the side connecting rod 131, a side mold limiting rod 132 is opened on the side mold limiting rod 132, and a side pin pre-set hole 133 is inserted in the side pin pre-set hole 133, and a plurality of limiting plates 17 are welded on the support frame unit 11 so that the integral bracket is used as the trolley body. The overall structure is light, and a pedestrian passage is reserved in the middle to facilitate the passage of people.

[0043] Two top mold plates 2 are provided on the top of the support frame 1, and the top mold plate 2 includes a top steel mold plate 21, and a top mold purlin 23 and a top mold truss 24 are welded on the top steel mold plate 21. A top mold reaction frame 25 is provided on the top mold reaction frame 25, and a top jack positioning block 26 is placed on the top mold reaction frame 25. A top demoulding jack 27 is placed in the top jack positioning block 26, and a top demoulding jack 27 is welded on the top of the top demoulding jack 27. The top demoulding reaction plate 22 is embedded in the top steel mold plate 21, and a top mold plate force transmission rod 5 is provided between the top mold plate 2 and the support frame unit 11, and the top mold plate force transmission rod 5 is located between the two limit plates 17 on the support frame unit 11.

[0044] The support frame unit 11 is provided with a top mold lifting assembly 4, and the top mold lifting assembly 4 includes a support rod 41 welded to the support frame unit 11, a lifting jack 42 is fixedly provided on the top of the support rod 41, and a force transmission rod 43 is fixedly provided on the top of the lifting jack 42.

[0045] First, fix the lifting jack 42 on the support rod 41. When installing the top template 2, pass the top template truss 24 through the top template limit rod 122 to prevent the top template 2 from moving left and right. After installing the top template, insert the top pin 124 into the top pin reserved hole 123, and then pass the force transmission rod 43 through the top template reaction frame 25. Open the lifting jack 42, lift the top template 2 into place, and place the top template force transmission rod 5 between the limit plates 17. At this time, the top template 2 is installed and fixed.

[0046] To support the sides, such as Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, two side formworks 3 are provided on both sides of the support frame 1, and the side formworks 3 include side steel formworks 31. The side steel formworks 31 are welded with side form purlins 33 and side form trusses 34 on the side facing the support frame 1, and the side form trusses 34 are provided with side form reaction frames 35. The side form reaction frames 35 are provided with side form jack positioning blocks 36, and the side form demoulding jacks 37 are placed on the side form jack positioning blocks 36. The side form demoulding reaction plates 32 are welded to one end of the side form jack positioning blocks 36, and the side form demoulding reaction plates 32 are embedded in the side steel formworks 31. A side formwork force transmission rod 6 is provided between the side formwork 3 and the support frame unit 11, and the side formwork force transmission rod 6 is located between the two limit plates 17 on the support frame unit 11.

[0047] After installing the top formwork 2, start installing the side formwork 3. Pass the side formwork truss 34 through the side formwork limit rod 132 to prevent the side formwork 3 from moving up and down. The side formwork limit rod 132 can be used as a track for the side formwork 3 to move left and right. Insert the side latch 134 with the flat head part on the top of the side latch 134 facing inward, push the side formwork 3 outward into place, place the side formwork force transmission rod 6 between the limit plates 17, and hoist the entire pipe gallery trolley into the pipe gallery. Multiple pipe gallery trolleys are connected by bolts passing through the reserved holes 16 of the support frame, the reserved holes 28 of the top formwork, and the reserved holes 38 of the side formwork.

[0048] In this way, the top formwork 2 uses two identical top steel formworks 21, and the side formworks 3 use four identical side steel formworks 31 on both sides. If part of the formwork is damaged, it can be directly replaced, which is convenient for maintenance and does not affect the construction. The top formwork 2, the side formwork 3 and the supporting frame 1 are connected respectively by the top formwork force transfer rod 5 and the side formwork force transfer rod 6, with high rigidity, and the top formwork 2 and the side formwork 3 will not sink or leak.

[0049] In order to support the support frame unit 11, as Figure 1 , Figure 2 , Fig.12 and Fig.13As shown, a plurality of support components 7 are provided at the bottom of the support frame unit 11, and the support component 7 includes a sleeve 71 welded to the bottom end of the support frame unit 11, and a support screw 73 is provided inside the sleeve 71. The bottom end of the support screw 73 extends to the bottom of the sleeve 71 and is fixed with a base 74. A nut 72 is provided at the outer end of the support screw 73 through a threaded sleeve, and the nut 72 is located at the bottom end of the sleeve 71.

[0050] A protrusion 75 is fixedly provided on both sides of the nut 72, and a scale rod 76 is provided at the bottom end of the protrusion 75. The scale rod 76 is marked with a scale reflecting the height, and a sleeve 77 is sleeved at the bottom end of the scale rod 76. A moving ball 78 in contact with the top of the base 74 is fixedly provided at the bottom end of the sleeve 77. A spring 79 is fixedly provided at the bottom end of the scale rod 76, and the bottom end of the spring 79 is fixedly connected to the inner wall of the sleeve 77.

[0051] After the multiple pipe gallery trolleys are connected, the nut 72 is rotated to make the nut 72 move upward along the support screw 73 and push the sleeve 71 upward. After the nut 72 is tightened, the sleeve 71 will push the support frame unit 11 upward, so as to use the support assembly 7 to support the support frame unit 11 and transmit the force of the support frame unit 11 to the ground. After the concrete pouring is completed, the top template force transmission rod 5 and the side template force transmission rod 6 are withdrawn, and the top demoulding jack 27 and the side template demoulding jack 37 are opened. The reaction forces of the two act on the top template reaction frame 25 and the side template reaction frame 35 respectively, and then are transmitted to the top template truss 24 and the side template truss 34, and then drive the top steel template 21 and the side steel template 31 to complete the demoulding and move to the next construction section for construction. In this way, each template module is equipped with an automatic demoulding structure, and the reaction force of the automatic demoulding structure is evenly transmitted to various parts of the template, so that various parts of the template are evenly stressed during the demoulding process, and will not cause problems such as template deformation and concrete surface peeling.

[0052] During the rotation of the nut 72, the scale rod 76 and the sleeve 77 rotate synchronously with the nut 72, and the movable ball 78 rolls on the base 74. At the same time, as the height of the nut 72 changes, the spring 79 will expand and contract, and the extension degree of the scale rod 76 above the sleeve 77 will change accordingly. The scale on the scale rod 76 can reflect the distance between the nut 72 and the base 74, and then reflect the supporting strength of the support assembly 7. In this way, the supporting strength of each support assembly 7 to the support frame unit 11 is kept consistent to avoid offset.

[0053] In order to move the trolley to the corresponding position, Figure 1 , Figure 2 , Fig.14 and Fig.15As shown, two moving components 8 are provided at the bottom of the support frame 1, and the moving component 8 includes a track 83 located at the bottom of the support frame unit 11, and two rotating wheels 82 are placed on the track 83. A vertical rod 81 is fixed at the bottom end of the bottom reinforcement tie rod 14, and the bottom end of the vertical rod 81 is rotatably connected to the rotating wheel 82.

[0054] Two rows of rubber gaskets 84 are fixed on the track 83 , and protective balls 85 are fixed on the rubber gaskets 84 . The protrusion of the track 83 is sandwiched between the two rotating wheels 82 , and the two rows of protective balls 85 are respectively located on both sides of the protrusion and contact the two rotating wheels 82 .

[0055] The moving component 8 is integrally welded to the supporting frame 1, and the supporting frame 1 can move in a straight line along the track 83 through the rolling of the rotating wheel 82. During the rolling of the rotating wheel 82, the inner side thereof will contact with the protective ball 85 and make it roll. The rolling of the protective ball 85 can prevent the rotating wheel 82 from rubbing against the raised part of the track 83. At the same time, with the lateral support of the rubber gasket 84 and the protective ball 85, the horizontal loosening of the rotating wheel 82 can be prevented, thereby ensuring that the supporting frame 1 can move in a straight line.

[0056] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
