Description

Technical Field

[0001] This utility model relates to the field of shield tunnel segment production technology, and in particular to a maintenance frame for shield tunnel segment production. Background Technology

[0002] With the booming development of urban rail transit construction, shield tunneling technology has been widely used in tunnel excavation due to its advantages of high efficiency, safety, and environmental friendliness. As a key supporting structure of shield tunnels, the quality of shield segments directly affects the stability and service life of the tunnel. The post-production curing process for the segments is crucial, directly determining their strength and durability.

[0003] In the existing technology, when maintaining shield tunnel segments, the shield tunnel segments are generally stacked on a maintenance frame and sprayed manually by holding a water pipe. However, due to the large volume and arc shape of the shield tunnel segments, it takes a lot of time to spray all the shield tunnel segments evenly during manual spraying. Therefore, a maintenance frame for shield tunnel segment production has been designed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a maintenance frame for the production of tunnel segments.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A maintenance frame for tunnel segment production includes a placement platform with a rectangular hole in the center. L-shaped support legs are fixedly connected to both ends of the bottom of the platform. A second horizontal tube is rotatably connected between the two L-shaped support legs near the rectangular hole. A rotating rod is rotatably fitted onto the bottom of the two L-shaped support legs at the bottom of the second horizontal tube. Both ends of the rotating rod rotatably pass through adjacent L-shaped support legs and are fixedly connected to rotating rods. Circular holes adapted to the rotating rods are opened on both L-shaped support legs. A connecting rod is fixedly connected to the top of the two rotating rods. An arc-shaped hole is opened at the bottom of one of the rotating rods, and the second horizontal tube is located in the arc-shaped hole. A first vertical hole is opened at the top of the arc-shaped hole on this side of the rotating rod. An L-shaped rod is fixedly connected to the end of the second horizontal tube near the first vertical hole, passing through the L-shaped support leg. The top of the L-shaped rod is slidably connected to the first vertical hole. The arrangement of the L-shaped rod and the first vertical hole allows the rotating rod to swing, causing the second horizontal tube to swing.

[0007] Preferably, the tops of the two rotating rods are fixedly connected to the same first horizontal tube at the bottom of the connecting rod.

[0008] Preferably, multiple second inclined nozzles are fixedly connected at equal intervals to the top of the second horizontal tube, and multiple limiting rods are fixedly connected at equal intervals to both sides of the rectangular hole on the top of the placement platform. The limiting rods facilitate the positioning of the shield tunnel segments, and multiple limiting rods on the same side are adapted to the second inclined nozzles.

[0009] Preferably, multiple first inclined nozzles are fixedly connected at equal intervals at the bottom of the first horizontal pipe, and the first inclined nozzles and the second inclined nozzles are inclined in opposite directions. This reverse inclination setting facilitates comprehensive spraying maintenance of the tunnel segments.

[0010] Preferably, a U-shaped plate is fixedly connected to the middle of the bottom of the placement platform, and a protective shell is fixedly connected to one side of the bottom of the U-shaped plate. A motor is fixedly connected inside the protective shell, and a turntable is fixedly connected to the output end of the motor through the U-shaped plate. A sliding rod is fixedly connected to the other edge of the turntable.

[0011] Preferably, a fixed rod is fixedly connected to the rotating rod near the turntable, and a sliding rod is slidably connected in the second vertical hole. By rotating the sliding rod and cooperating with the second vertical hole, the rotating rod can swing.

[0012] Preferably, one end of the second horizontal pipe and one end of the first horizontal pipe are connected to the same water supply hose, and the water supply hose is equipped with a control valve.

[0013] The beneficial effects of this utility model are as follows:

[0014] By employing techniques such as a fixed rod, a rotating rod, a first horizontal pipe, a first inclined nozzle, an L-shaped rod, and a second inclined nozzle, the rotating rod is driven by a motor to swing, causing the first horizontal pipe to reciprocate between the two sides of the top of the shield tunnel segment. Simultaneously, the rotating rod can drive the second horizontal pipe to swing, allowing the second inclined nozzle to spray the concave side of the shield tunnel segment. This solves the problem of incomplete spraying mentioned in the background technology, thereby ensuring that all parts of the top of the segment, including both sides and the concave side, are evenly covered, avoiding localized drying or insufficient curing, greatly improving the quality of curing. It also eliminates the need for manual operation of the nozzles, reducing labor intensity and manpower input. Attached Figure Description

[0020] 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.

[0021] Reference Figures 1-4 A maintenance frame for tunnel segment production includes a placement platform 1 with a rectangular hole 101 in the center. L-shaped support legs 2 are fixedly connected to both ends of the bottom of the placement platform 1. A second horizontal pipe 7 is rotatably connected between the two L-shaped support legs 2 near the rectangular hole 101. A rotating rod 5 is rotatably fitted onto the bottom of the two L-shaped support legs 2 at the bottom of the second horizontal pipe 7. Both ends of the rotating rod 5 rotatably pass through the adjacent L-shaped support legs 2 and are fixedly connected to rotating rods 4. Circular holes adapted to the rotating rods 5 are provided on both L-shaped support legs 2. The tops of the two rotating rods 4 are fixedly... The two sides are connected by the same connecting rod 401. One of the rotating rods 4 has an arc-shaped hole 405 at its bottom, and the second horizontal tube 7 is located in the arc-shaped hole 405. The rotating rod 4 on this side has a first vertical hole 404 at the top of the arc-shaped hole 405. The end of the second horizontal tube 7 near the first vertical hole 404 passes through the L-shaped support leg 2 and is fixedly connected to an L-shaped rod 701. The top of the L-shaped rod 701 is slidably connected in the first vertical hole 404. Through the cooperation between the L-shaped rod 701 and the first vertical hole 404, the rotating rod 4 will drive the second horizontal tube 7 to swing when it swings.

[0022] In this invention, the tops of the two rotating rods 4 are fixedly connected to the same first horizontal tube 402 at the bottom of the connecting rod 401.

[0023] In this utility model, multiple second inclined nozzles 702 are fixedly connected at equal distances to the top of the second horizontal tube 7, and multiple limiting rods 3 are fixedly connected at equal distances to both sides of the rectangular hole 101 on the top of the placement platform 1, and the multiple limiting rods 3 on the same side are adapted to the second inclined nozzles 702.

[0024] In this invention, a plurality of first inclined nozzles 403 are fixedly connected at equal intervals at the bottom of the first horizontal pipe 402, and the first inclined nozzles 403 and the second inclined nozzles 702 are inclined in opposite directions. By setting the second inclined nozzles 702 and the first inclined nozzles 403 to be inclined, the spraying effect is better.

[0025] In this utility model, a U-shaped plate 8 is fixedly connected to the middle of the bottom of the placement platform 1, and a protective shell 9 is fixedly connected to one side of the bottom of the U-shaped plate 8. A motor is fixedly connected inside the protective shell 9, and a turntable 901 is fixedly connected to the output end of the motor through the U-shaped plate 8. A sliding rod 902 is fixedly connected to the other edge of the turntable 901.

[0026] In this utility model, a fixed rod 501 is fixedly connected to the rotating rod 5 near the turntable 901, and a sliding rod 902 is slidably connected in the second vertical hole 502. Through the cooperation between the sliding rod 902 and the second vertical hole 502, the rotating rod 5 and the rotating rod 4 can swing when the motor rotates.

[0027] In this invention, one end of the second horizontal pipe 7 and the first horizontal pipe 402 are both connected to the same water supply hose, and a control valve is provided on the water supply hose to supply water to the second inclined nozzle 702 and the first inclined nozzle 403.

[0028] Working principle: When using this maintenance frame, the motor is first connected to the mains power. The rotation of the motor positions the connecting rod 401 and the first horizontal tube 402 at the top edge of the placement platform 1, facilitating the hoisting of the tunnel segments. Figure 1The tunnel segments are arranged in a manner that ensures each segment is in contact with two limiting rods 3 on its convex side. This arrangement also ensures that each segment has a second inclined nozzle 702 at the bottom of its concave side. After arranging the tunnel segments in this way, when maintenance is required, the control valve on the water supply hose is opened, causing the multiple second inclined nozzles 702 and the first inclined nozzles 403 to spray water. The number of first inclined nozzles 403 is much greater than that of second inclined nozzles 702. Then, the motor is started, causing the turntable 901 to rotate. With the cooperation of the sliding rod 902 and the second vertical hole 502, the fixed rod 501 swings along with the rotating rod 5. This causes the rotating rod 4 to swing between the two sides of the top shield tunnel segment, along with the first horizontal pipe 402. With the first inclined nozzle 403 tilted, the top, sides, and convex side of the shield tunnel segment are all sprayed. Since the top of the L-shaped rod 701 slides in the first vertical hole 404, when the rotating rod 4 swings, it drives the second horizontal pipe 7 and the second inclined nozzle 702 to swing, thus ensuring that the convex side of the shield tunnel segment is also sprayed evenly, achieving a curing effect. The arrangement of the second inclined nozzle 702 and the first inclined nozzle 403 makes it easy for the curing frame to spray multiple shield tunnel segments evenly, improving the efficiency of curing.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
