Technical Field

[0001] The invention relates to the technical field of platform slab casting equipment, and in particular to a trolley used for casting platform slabs of subway stations. Background Art

[0002] The platform slab, which is the platform before pedestrians get on the train, is an important internal structural component in the subway station operation system. It is located in the pedestrian area above the station floor. Due to its special location, it is generally not cast at the same time as the main body of the station. Especially in stations where shield construction needs to pass, the platform slab must be cast later.

[0003] The existing post-casting construction method usually adopts the form of setting up steel pipe scaffolding and wooden formwork in sections. After the support is set up, the bottom plate formwork is installed, the bottom plate and vertical wall steel bars are tied, the outer formwork of the vertical wall is installed, and the bottom plate and the lower vertical wall concrete are poured. When the concrete solidifies to a certain strength, the inner formwork of the vertical wall is installed and reinforced, and finally the upper concrete of the vertical wall is poured. After the construction is completed and meets the requirements for demolding, the support system and formwork are removed, and the cycle is carried out to the next stage of construction.

The track is used to support and position the roller to facilitate the movement of the vehicle body.

[0021] The present invention is further configured as follows: a limiting groove is provided on the track, and the roller is movably arranged in the limiting groove.

[0022] By adopting the above technical solution, the limit groove can limit the roller, and then limit the direction of movement of the vehicle body, so that the vehicle body moves along the direction of the track, preventing the roller from offset and causing misalignment deviation in the movement of the vehicle body, thereby avoiding affecting the construction accuracy.

[0036] Reference Figure 1 and Figure 2Each group of casting molds 2 includes a first top mold 21 and a second top mold 22 which are horizontally connected in sequence from the side of the vehicle body 1 to the direction close to the fixed top mold 3. One side of the first top mold 21 is fixed to one side of the second top mold 22 by bolts, and the other side of the second top mold 22 is fixed to one side of the fixed top mold 3 by bolts. The edge of the upper surface of the first top mold 21, the edge of the upper surface of the second top mold 22, and the edge of the upper surface of the fixed top mold 3 are vertically fixedly connected with a baffle 6 by bolts. A rectangular first casting groove 27 is provided at the connection between the first top mold 21 and the second top mold 22, and a rectangular second casting groove 28 is provided at the connection between the second top mold 22 and the fixed top mold 3. The size of the first casting groove 27 is consistent with the size of the second casting groove 28.

[0037] The two side edges of the notch of the first casting trough 27 are respectively connected to the first side mold 23 and the second side mold 24. The top of the first side mold 23 is hinged to the lower surface of the first top mold 21, and the top of the second side mold 24 is hinged to the lower surface of the second top mold 22. When the first side mold 23 and the second side mold 24 are rotated to a vertical state, a first casting cavity 7 is formed between the first side mold 23 and the second side mold 24, and the first casting trough 27 is connected to the first casting cavity 7.

[0038] The third side mold 25 and the fourth side mold 26 are connected to the two sides of the notch of the second casting groove 28, respectively. The first side mold 23, the second side mold 24, the third side mold 25 and the fourth side mold 26 are of the same size. The top of the third side mold 25 is hinged to the lower surface of the second top mold 22, and the top of the fourth side mold 26 is hinged to the lower surface of the fixed top mold 3. When the third side mold 25 and the fourth side mold 26 are both rotated to a vertical state, a second casting cavity 8 is formed between the third side mold 25 and the fourth side mold 26, and the second casting groove 28 is connected to the second casting cavity 8.

[0039] The support mechanism 4 includes an outer support rod 41 connected to the outer side of the first side mold 23 and the outer side of the fourth side mold 26, an inner support rod 42 connected to the outer side of the second side mold 24 and the outer side of the third side mold 25, and a hydraulic cylinder 43 for supporting the second top mold 22. One end of the hydraulic cylinder 43 is fixedly connected to the vehicle body 1, and the other end of the hydraulic cylinder 43 abuts against the middle of the lower surface of the second top mold 22. One end of the outer support rod 41 is hinged to the first side mold 23 and the fourth side mold 26, and the other end of the outer support rod 41 is anchored to the ground. In this embodiment, the inner support rod 42 is a hydraulic support rod, one end of the inner support rod 42 is hinged to the second side mold 24 and the third side mold 25, and the other end of the inner support rod 42 is hinged to the outer wall of the hydraulic cylinder 43.

[0040] Reference Figure 1 and Figure 3The traveling mechanism 5 includes rollers 51 fixed to both sides of the bottom of the vehicle body 1, two tracks 53 fixed to the ground by bolts and matched with the rollers 51, and two motors 52 for driving the rollers 51 to rotate. The two motors 52 are symmetrically installed on both sides of the vehicle body 1 by bolts. A group of rollers 51 are installed at both ends of the front and rear sides of the vehicle body 1, and each group includes two rollers 51. A connecting shaft 511 is fixedly connected between the two rollers 51 of the same group. A driven bevel gear 512 is sleeved on the outer side of the connecting shaft 511, and the driven bevel gear 512 is located between the two rollers 51. The rotating shafts of the two motors 52 are fixedly sleeved with a driving bevel gear 521, and the driving bevel gear 521 matches the driven bevel gear 512.

[0041] During construction, the motor 52 drives the roller 51 to roll along the track 53, thereby driving the vehicle body 1 to move to the preset construction position, and the first top mold 21, the second top mold 22 and the fixed top mold 3 are connected in sequence and the baffle 6 is installed, and then the first side mold 23, the second side mold 24, the third side mold 25 and the fourth side mold 26 are rotated to a vertical state and supported and fixed by the support mechanism 4. The outer support rod 41 is used to support and fix the first side mold 23 and the fourth side mold 26, and the inner support rod 42 is used to support and fix the second side mold 24 and the third side mold 25, which improves the overall firmness and structural strength of the template to avoid the loosening and displacement of the template and cause deviation in the forming of the side wall.

[0042] Then concrete is added from the first casting trough 27 and the second casting trough 28 into the first casting cavity 7 and the second casting cavity 8 respectively to form side walls. When the first casting cavity 7 and the second casting cavity 8 are full, the concrete overflows from the first casting trough 27 and the second casting trough 28. The first top form 21, the second top form 22, the fixed top form 3 and the baffle 6 cooperate to shape the concrete into a platform slab.

[0043] After the side walls and platform slabs are solidified and formed, the support mechanism 4 is released, the first top mold 21 is removed, and the inner support rod 42 contracts to drive the second side mold 24 and the third side mold 25 to rotate in the direction close to the hydraulic cylinder 43. The vehicle body 1 is driven to move by the driving mechanism 5, and the vehicle body 1 transports the template to the next section for construction. This cycle greatly reduces the amount and difficulty of disassembly and assembly of the template, can save a lot of time and manpower, improve construction efficiency, shorten the construction period, and also reduce the cost caused by disassembly and damage of the template during construction.

[0044] Reference Figure 1The supporting mechanism 4 also includes a jack 44 fixedly mounted on the middle top of the vehicle body 1 by bolts, and the top of the jack 44 abuts against the middle of the lower surface of the fixed top mold 3. The jack 44 is used to support the fixed top mold 3, thereby improving the firmness and structural strength of the fixed top mold 3, avoiding deformation of the fixed top mold 3 due to excessive weight during the molding of the platform plate, and improving the molding quality of the platform plate.

[0045] Reference Figure 3 , both rails 53 are provided with limiting grooves 531, and the rollers 51 are movably installed in the limiting grooves 531. When the vehicle body 1 moves, the limiting grooves 531 can limit the rollers 51, and then limit the moving direction of the vehicle body 1, so that the vehicle body 1 moves along the direction of the rails 53, preventing the rollers 51 from shifting and causing misalignment deviation in the movement of the vehicle body 1, so as to avoid affecting the construction accuracy.

[0046] A rubber buffer layer 513 is also provided on the outside of each roller 51 to protect the roller 51 and prevent significant wear between the roller 51 and the inner wall of the limiting groove 531 , thereby preventing the roller 51 from being worn so much that the normal rolling of the roller 51 is affected.

[0047] The implementation principle of this embodiment is: by setting the driving mechanism 5 to drive the vehicle body 1 to drive the template to move between the work sections for construction, the amount and difficulty of disassembly and assembly of the template are greatly reduced, a lot of time and manpower are saved, the efficiency of construction is improved, the construction period is shortened, and the cost caused by the damage of the template during the construction process is also reduced. By setting the support mechanism 4 to improve the overall firmness and structural strength of the template, the loosening and displacement of the template is avoided to prevent the deviation of the side wall from forming, thereby improving the quality of construction.

[0048] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, all equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
