Description

Technical Field

[0001] The utility model relates to the technical field of tunnel casting, in particular to a casting system for a tunnel trolley. Background Art

[0002] With economic development and convenient transportation, more and more tunnels are being built. However, during the tunnel construction process, the construction process of the tunnel is to first do initial support, then lay a waterproof layer, and then use a trolley to support the formwork so that there is a casting space between the formwork and the waterproof layer (each formwork generally has three casting ports on both sides), and then cast into the casting space.

[0003] The existing trolley supports the formwork in the following way: the trolley has multiple outward radial struts on the circumference of the area corresponding to each formwork, and the formwork is supported by multiple radial struts; the existing casting system corresponding to the trolley includes a main casting pipe, which first casts the tunnel side A, and then moves to the B side for casting; specifically, taking the casting side A as an example, the worker controls the casting pipe to cast from the first formwork and the casting port from bottom to top, and then pulls the casting to cast the next formwork. This method has the following defects: 1. The casting pipe needs to be docked with each formwork six times (three times on the A side and three times on the B side), and the casting operation cannot be performed during the switching of the casting port, thus restricting the casting efficiency; 2. Since the trolley supports the formwork through multiple radially arranged struts, the barrier-free space between the trolley and the formwork is small, which affects the control and movement of the casting pipe and the staff, and further affects the casting operation.

[0004] To this end, we designed a casting system for a tunnel trolley to solve at least one of the above-mentioned defects. Utility Model Content

DETAILED DESCRIPTION

[0025] The present invention can be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. In the description of the present invention, it should be understood that if there are terms such as "upper", "lower", "front", "back", "left", "right", etc. to indicate directions or positional relationships, they only correspond to the drawings of the present application, in order to facilitate the description of the present invention; it should be understood that if there are terms such as "end", "side", "end part", "lateral", "lateral", "transverse", "longitudinal", etc. to indicate directions or positional relationships, they only correspond to the length and width of the corresponding parts, that is, "end part" indicates the head and tail areas in the length direction of the corresponding part, and "side part" indicates the head and tail areas in the width direction of the corresponding part; this is for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific direction.

[0026] Embodiment 1, in combination with the attached Figure 1 A casting system for a tunnel trolley comprises a trolley 1, a template 2 and a casting pipe 3 which are arranged in sequence outside the trolley 1 and along the length direction of the trolley 1, each side of the template 2 has three casting ports spaced apart from each other, three n-type frames 11 are arranged on the top of the trolley 1 along its width direction, and the two ends of the open end of the n-type frame 11 are respectively fixedly connected to the two ends of the trolley 1, and the closed ends of the n-type frames 11 on both sides are higher than the top casting port on the side of the template 2; the closed ends of the n-type frames 11 are provided with an electric hoist device 12 which can move along the length direction thereof, so as to facilitate pulling the casting pipe 3 by the electric hoist device 12.

[0027] Compared with the prior art, this arrangement replaces the radially arranged support rods in the prior art with axially arranged n-type frames 11. All templates are supported by three n-type frames 11, providing an obstacle-free axial movement space for pulling the casting pipe 3. Combined with the electric hoist device 12, the function of pulling the casting pipe 3 by means of the equipment is realized, which is more labor-saving and reduces labor intensity compared with manual pulling in the prior art.

[0028] Embodiment 2, combined with the attached Figure 1-2 , a casting system for a tunnel trolley, based on the first embodiment, both sides of the template 2 are provided with fixed pipes 4 connected with three casting ports on the corresponding sides.

[0029] The fixed pipeline 4 includes a main pipeline 41, which is connected to three fixed branches 42 at intervals from top to bottom, and the lowest fixed branch 42 is connected to the lower end of the main pipeline 41, and the outer ends of the three fixed branches 42 are connected one by one to the three casting ports on the side of the corresponding template 2.

[0030] Specifically, the upper end of the main pipe 41 has a joint connected to the branch casting pipe 3. Since there are many joint structures in the prior art that can realize detachable connection between two pipes, the joint will not be described in detail here.

[0031] This arrangement allows casting to be performed after the casting pipe 3 is connected to the upper end of the main pipe 41. At this time, concrete will be cast in sequence from the bottom to the top of the fixed branch pipe 42. Therefore, the casting pipe 3 can complete the casting operation of the side formwork after only one connection, thereby greatly improving the casting efficiency.

[0032] As required, the fixed branch pipe 42 is arranged to be tilted up and down, and the end corresponding to the main pipe 41 is the upper end.

[0033] Embodiment 3, in combination with the attached Figure 1-3 A casting system for a tunnel trolley, based on embodiment one or two, the casting pipeline 3 includes a three-way valve 31, the feeding end of the three-way valve 31 is connected to a main casting pipe 32, the two discharge ends of the three-way valve 31 are connected to branch casting pipes 33, and the branch casting pipes 33 are correspondingly connected to the corresponding electric hoist device 12.

[0034] When this embodiment is implemented on the basis of the first embodiment, compared with the prior art, it can simultaneously cast on both sides of the template, thereby improving the casting efficiency, and when one of the branch casting pipes 33 switches the casting port, the three-way valve 31 is used to control the branch casting pipe 33 to disconnect the passage to prevent material waste.

[0035] When this embodiment is implemented on the basis of the second embodiment, the casting can be performed after the branch casting pipe 33 is connected to the upper end of the main pipeline 41. At this time, the concrete will be cast in sequence from the bottom to the top of the fixed branch pipe 42. Therefore, the two branch casting pipes 33 can be cast on both sides of the template at the same time, and each branch casting pipe 33 is only connected once to complete the casting operation of the template, thereby greatly improving the casting efficiency. When one of the branch casting pipes 33 switches the main pipeline 41, the three-way valve 31 is used to control the branch casting pipe 33 to disconnect the passage to prevent material waste.

[0036] It should be noted that before pouring, the three-way valve 31 needs to be placed in the middle of the top surface of the trolley 1, so that when the supporting casting pipe 33 is pulled by the electric hoist device 12, the position of the three-way valve 31 remains almost unchanged, and the position of the main casting pipe 32 will not change.

[0037] Embodiment 4, in combination with the attached Figure 2-4 , a casting system for a tunnel trolley. On the basis of embodiment three, a through groove 13 is provided in the middle of the top surface of the trolley 1 for the feeding end of the three-way valve 31 or the main casting pipe 32 to pass through; this arrangement can place the main casting pipe 32 under the trolley 1, which is more convenient than laying the casting pipeline 3 on the top surface of the trolley 1.

[0038] As needed, the through groove 13 can be a short through groove for fixing the position of the three-way valve 31; specifically, the three-way valve 31 can move in a small range in the middle of the top surface of the trolley 1, or it can be fixed; as needed, the through groove 13 can also be a long through groove arranged along the length direction of the top surface of the trolley 1, so that the three-way valve 31 can move along the length direction of the top surface of the trolley 1.

[0039] When the through groove 13 is a long through groove arranged in the length direction of the top surface of the trolley 1, a movable support seat 5 is arranged at the feeding end of the three-way valve 31, and the movable support seat 5 is movably matched with the top surface of the trolley 1;

[0040] A through hole is provided in the middle of the movable support seat 5 for the feeding end of the three-way valve 31 to pass through, and both ends of the movable support seat 5 are provided with running wheels 51 which roll on the top surface of the trolley 1 .

[0041] This arrangement enables the three-way valve 31 to move smoothly on the movable support seat 5 when the casting pipe 33 is pulled by the electric hoist device 12, and ensures that the three-way valve 31 does not contact the trolley 1, thereby preventing the three-way valve 31 from being worn.

[0042] As needed, the movable support seat 5 can pass through the through groove 13 after being flipped 90 degrees; that is, when disassembling, the three-way valve 31 can be moved so that the movable support seat 5 is sleeved on the main casting pipe 32. At this time, the movable support seat 5 can be flipped to 90 degrees so that the movable support seat 5 passes through the through groove 13, and then the three-way valve 31 and the branch casting pipe 33 can be pulled out from under the through groove 13; in this way, the casting pipeline 3 can be laid out from below.

[0043] The parts of the present invention that are not described in detail are prior art. It is obvious to those skilled in the art that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and it is intended that all changes that fall within the meaning and scope of equivalent elements are included in the present invention.
