Description

Technical Field

[0001] This utility model belongs to the field of precast pipe pile technology, and in particular relates to a fixing device for triangular pile molds. Background Technology

[0002] The fixing device for triangular pile molds is typically used to ensure that concrete maintains a stable and precise shape during pouring and curing. The locking mechanism of the fixing device connects and secures the upper and lower mold bases, preventing loosening during use. Common locking methods include bolt connections and quick-locking clips. However, due to insufficient locking force in the locking mechanisms of mold fixing devices in related technologies, triangular pile molds are prone to loosening during use. Summary of the Invention

[0003] In view of this, the present invention aims to at least partially solve one of the related technical problems.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A fixing device for a triangular pile mold includes a fixing frame, two connecting crossbars and multiple locking mechanisms;

[0006] The two connecting crossbars are arranged side by side, and the ends of the two connecting crossbars are detachably connected to the fixed frame;

[0007] The multiple locking mechanisms are symmetrically arranged on the left and right, and the locking mechanisms on the same side are detachably connected to one of the connecting crossbars;

[0008] The locking mechanism includes a guide structure, a fastening structure, and two clamping plate structures. The two clamping plate structures are arranged symmetrically above and below each other. The outer ends of the clamping plate structures are connected to the fastening structure, and the inner ends of the clamping plate structures are used to clamp the upper or lower mold base of the triangular pile mold. Both clamping plate structures are slidably engaged with the guide structure, and the guide structure is detachably connected to the crossbar.

[0009] Furthermore, the guide structure includes a fixed plate and a guide plate, the guide plate is disposed on the inner end face of the fixed plate, the guide plate is slidably engaged with the clamping plate structure, and the fixed plate is detachably connected to the crossbar.

[0010] Furthermore, the clamping plate structure includes a pressure plate, a clamping plate, and two connecting plates. The pressure plate is connected to the fastening structure. The pressure plate is connected to the outer end of the clamping plate through the two connecting plates. The inner end of the clamping plate is provided with a clamping bend. The clamping bend can cooperate with the upper or lower module of the triangular pile mold. The outer end of the clamping plate is slidably engaged with the guide plate.

[0011] Furthermore, the fastening structure includes an adjustment knob and two adjustment screws. The two adjustment screws are symmetrically arranged on the upper and lower end faces of the adjustment knob. The threads of the two adjustment screws have opposite directions, and each adjustment screw corresponds to a clamping plate thread engagement with a clamping plate structure.

[0012] Furthermore, the outer wall of the adjustment knob has a hexagonal edge structure.

[0013] Furthermore, the fixed frame has a C-shaped cross-section, and the crossbar is connected to the end of the fixed frame by bolts.

[0014] Furthermore, the end of the crossbar that connects to the fixed frame is provided with a thickened pad.

[0015] Furthermore, the fastening structure also includes two locking nuts, with one locking nut corresponding to each adjusting bolt, and the locking nuts are used to lock the pressure plate.

[0016] Compared with the prior art, the fixing device for triangular pile molds described in this utility model has the following advantages:

[0017] 1. Multiple locking mechanisms ensure that the mold receives uniform pressure in all directions, reducing deformation and instability caused by a single point of force. By distributing the locking points, the stability of the mold is effectively increased, preventing shaking or displacement during processing. Since multiple locking mechanisms can be adjusted independently, they can be tailored to different sizes and shapes of molds, increasing the applicability of the device.

[0018] 2. The upper and lower adjusting screws in the fastening structure use opposite-direction threads. When the single hexagonal adjusting knob is rotated, the upper and lower clamping plates move synchronously in opposite directions (closing or opening), forming a symmetrical clamping force. This ensures that the clamping force is evenly distributed on the upper and lower mold bases, eliminating mold offset or warping caused by unilateral force application. The clamping force deviation can be controlled within ±5%. The symmetrical layout of the clamping plate structure and the synergistic effect of the reverse threads allow the adjusting screws made of spring steel (elastic modulus 210GPa) to automatically compensate for stress changes through slight elastic deformation when the mold is heated or vibrates, maintaining a constant clamping force and avoiding over-constraint damage to the mold. The clamping plates adopt a dual-hardness composite structure: the surface of the clamping bend is overlaid with a wear-resistant alloy layer (hardness HRC55-60), and the substrate is tempered medium carbon steel (hardness HRC28-32). This ensures the wear resistance of the clamping surface and absorbs impact energy through the elastic deformation of the substrate, protecting the integrity of the mold coating.

[0029] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] A fixing device for triangular pile molds, such as Figure 1 As shown, the system includes a fixed frame 500, two connecting crossbars 400, and multiple locking mechanisms. The two connecting crossbars 400 are arranged side by side, and the ends of both connecting crossbars 400 are detachably connected to the fixed frame 500. The multiple locking mechanisms are arranged symmetrically on the left and right sides, and the two locking mechanisms on the same side are detachably connected to one connecting crossbar 400. The fixed frame 500 has a C-shaped cross-section, and the crossbars 400 are connected to the ends of the fixed frame 500 by bolts 510. The ends of the crossbars 400 connected to the fixed frame 500 are provided with thickened pads 410.

[0031] like Figure 2 As shown, the locking mechanism includes a guide structure 201, a fastening structure, and two clamping plate structures 300. The two clamping plate structures 300 are symmetrically arranged vertically. The outer ends of the clamping plate structures 300 are connected to the fastening structure, and the inner ends of the clamping plate structures 300 are used to clamp the upper or lower mold base of the triangular pile mold. Both clamping plate structures 300 are slidably engaged with the guide structure 201, and the guide structure 201 is detachably connected to the crossbar 400. Multiple locking mechanisms ensure that the mold receives uniform pressure in all directions, reducing deformation and instability caused by a single force point. By distributing the locking points, the stability of the mold fixation can be effectively increased, preventing shaking or displacement during processing. Since multiple locking mechanisms can be adjusted independently, they can be adjusted according to specific needs to adapt to molds of different sizes and shapes, increasing the applicability of the device.

[0032] The guide structure 201 includes a fixed plate and a guide plate. The guide plate is disposed on the inner end face of the fixed plate. The guide plate is slidably engaged with the clamping plate structure 300. The fixed plate is connected to the crossbar 400 by screws.

[0033] The clamping plate structure 300 includes a pressure plate 310, a clamping plate 330, and two connecting plates 320. The pressure plate 310 is connected to the fastening structure. The pressure plate 310 is connected to the outer end of the clamping plate 330 through the two connecting plates 320. The inner end of the clamping plate 330 is provided with a clamping bend 340. The clamping bend 340 can cooperate with the upper or lower module of the triangular pile mold. The outer end of the clamping plate 330 is slidably engaged with the guide plate.

[0034] The fastening structure includes an adjusting knob 101 and two adjusting screws 102. The two adjusting screws 102 are symmetrically arranged on the upper and lower end faces of the adjusting knob 101, and the threads of the two adjusting screws 102 have opposite directions. Each adjusting screw 102 corresponds to a threaded engagement with a pressure plate 310 of a clamping plate structure 300. The outer wall of the adjusting knob 101 has a hexagonal edge structure. The fastening structure also includes two locking nuts 103, one of which is provided on each adjusting bolt 510. The locking nuts 103 are used to lock the pressure plate 310.

[0035] In the fastening structure, the upper and lower adjusting screws 102 adopt opposite-direction threads. When the single hexagonal adjusting knob 101 is rotated, the upper and lower clamping plate structures 300 move synchronously in opposite directions (closing or opening), forming a symmetrical clamping force. This ensures that the clamping force is evenly distributed on the upper and lower mold bases, eliminating mold offset or warping caused by unilateral force application. The clamping force deviation can be controlled within ±5%. The symmetrical layout of the upper and lower clamping plate structures 300, together with the reverse threads, allows the adjusting screws 102 (elastic modulus 210 GPa) made of spring steel to automatically compensate for stress changes through slight elastic deformation when the mold is heated or vibrates, maintaining a constant clamping force and avoiding over-constraint damage to the mold. The clamping plate 330 adopts a dual-hardness composite structure: the surface of the clamping bend 340 is overlaid with a wear-resistant alloy layer (hardness HRC55-60), and the substrate is tempered medium carbon steel (hardness HRC28-32). This ensures the wear resistance of the clamping surface and absorbs impact energy through the elastic deformation of the substrate, protecting the integrity of the mold coating.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
