Description

Technical Field

[0001] This utility model relates to the field of pipe gallery mold technology, and more specifically, to a rapid assembly structure for prefabricated pipe gallery molds. Background Technology

[0002] The utility tunnel mold is a large-frame steel mold made of steel plates with a specification of over one meter. It is mainly used in urban underground integrated utility tunnel projects. The existing utility tunnel mold consists of an outer frame and inner side frames. After the frame is assembled, it is fixed with assembly fasteners. The existing assembly fasteners use two fasteners combined with bolts for fixation. To ensure the stability of the utility tunnel mold, multiple assembly fasteners are required. This makes the fixing and dismantling process cumbersome as it requires the operation of multiple fasteners. In view of this, we propose a rapid assembly structure for prefabricated utility tunnel molds. Utility Model Content

[0006] Preferably, the plurality of bevel gears are arranged in a triangular pattern on the side mold of the tube gallery, and a drive motor is fixed at another corner of the side mold of the tube gallery, with the drive end of the drive motor fixed to the end of the straight rod.

[0007] Preferably, the constraint head includes a helical sphere, one side of which is in contact with the outer periphery of the straight rod, and the helical sphere has a slot, the inner wall of which is in close contact with the outer periphery of the straight rod.

[0008] Preferably, the slot has a spiral trajectory design, and the spiral trajectory of the slot moves gradually towards the center of the straight rod, and the distance between the straight rods gradually decreases as the straight rods move within the slot.

[0009] Preferably, the outer periphery of the plurality of spiral circles on the upper side is connected to a stacking plate, and the stacking plate is a rectangular plate structure.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This utility model, through the arrangement of straight rods on all four sides and the meshing design of bevel gears, and the fixing of straight rods to side molds and clamping rods to outer frame molds, combined with the fixing of constraint heads to straight rods and the design that clamping rods can be inserted into slots, can make multiple straight rods and constraint heads rotate synchronously when the drive motor is running, so as to achieve the effect of constraint engagement. Thus, one motor can drive the synchronous fixing of multiple sides, making it quick to disassemble and assemble, and solving the problem that the disassembly and assembly process of pipe gallery molds is very troublesome.

[0020] like Figures 1 to 4As shown, this utility model relates to a rapid assembly structure for prefabricated pipe gallery molds, including a pipe gallery outer frame mold 1, and a pipe gallery side mold 2 provided on the side of the pipe gallery outer frame mold 1. The pipe gallery outer frame mold 1 and the pipe gallery side mold 2 can be assembled with the inner frame. This directly adopts existing technology, so it will not be described in detail. A plurality of straight rods 3 are provided on one side of the pipe gallery side mold 2. A rotating shaft 4 is rotatably connected to the outer periphery of the straight rods 3. The outer periphery of the rotating shaft 4 is fixed to one side of the pipe gallery side mold 2. The rotating shaft 4 and the pipe gallery side mold 2 are connected by a connecting rod frame. A locking rod 6 is provided on one side of the straight rods 3. A connecting frame 7 is connected between the clamping rod 6 and the outer frame mold 1 of the pipe gallery. Multiple constraint heads 8 are connected to the outer periphery of the straight rod 3. The constraint heads 8 are provided with a slot 802. A drive unit 5 is provided between the multiple straight rods 3. The drive unit 5 includes several bevel gears 501. The bevel gears 501 are fixed to the ends of the straight rods 3. Two bevel gears 501 at the same angle mesh with each other. The multiple bevel gears 501 are triangularly distributed in the side mold 2 of the pipe gallery. A drive motor 502 is fixed at another corner of the side mold 2 of the pipe gallery. The drive end of the drive motor 502 is fixed to the end of the straight rod 3.

[0021] Working principle: When in use, the external control combined with the control drive motor 502 runs, driving the straight rod 3 to rotate, causing the bevel gear 501 at the end to rotate. Through the meshing of the bevel gear 501, multiple straight rods 3 rotate synchronously, causing multiple constraint heads 8 to rotate synchronously, further causing the slot 802 to engage with the clamping rod 6, thus completing the locking.

[0022] To achieve auxiliary positioning, the constraint head 8 includes a spiral circle 801. One side of the spiral circle 801 is in contact with the outer periphery of the straight rod 3. Multiple spiral circles 801 on the upper side are connected to a stacking plate 803 on their outer periphery. The stacking plate 803 is a rectangular plate structure. The slot 802 is opened in the spiral circle 801. The slot 802 has a spiral trajectory design. The spiral trajectory of the slot 802 moves gradually towards the center of the straight rod 3. The distance between the straight rods 3 gradually decreases as they move within the slot 802.

[0023] In use, the erection plate 803 is first hoisted to the position of the uppermost clamping rod 6, which can play an auxiliary support role. With the help of external hoisting equipment, the side mold 2 of the pipe rack is moved to the approximate position so that the spiral body 801 is close to the clamping rod 6. At this time, the drive motor 502 is started to run, driving the spiral body 801 to rotate. The clamping groove 802 will engage the clamping rod 6. Due to the design of the spiral trajectory, the clamping rod 6 can move synchronously inside the clamping groove 802. As the distance gradually decreases, the side mold 2 of the pipe rack gradually becomes close to the outer frame mold 1 of the pipe rack, achieving the assembly effect. Thus, the spiral design of the clamping groove 802 can achieve the positioning function.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
