DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figures 1 to 4 As shown, the utility model provides a TBM pea-grain grouting mold, including a chassis 1, two main mold uprights 2 are arranged on the top of the chassis 1, and two side mold uprights 3 are arranged on the top of the chassis 1. The two ends of the main mold uprights 2 are tightly fitted with the facing surfaces of the left and right side mold uprights 3 respectively, and a locking assembly 4 is arranged inside the chassis 1;

[0023] The locking assembly 4 includes a limiting groove 41 opened around the chassis 1, and a plurality of transmission gears 43 are rotatably engaged with the limiting groove 41. The upper end of the transmission gear 43 extends to the top of the chassis 1 and is fixedly connected with a locking screw 44. A transmission belt 42 located outside the plurality of transmission gears 43 is movably installed inside the limiting groove 41, and the inner wall of the transmission belt 42 is meshedly connected with the outer surface of the plurality of transmission gears 43. Due to the setting of the locking assembly 4, the operating assembly 5 can drive the plurality of locking assemblies 4 to rotate at the same time, and then with the cooperation of the connecting positioning hole and the connecting locking hole, the plurality of locking assemblies 4 can be quickly screwed into their respective corresponding connecting locking holes at the same time, thereby quickly completing the assembly and fixation of the main mold plate 2 and the side mold plate 3.

[0024] like Figure 4 As shown, several transmission gears 43 located on the same side of the limiting groove 41 in front, back, left and right directions are located on the same arc, and the center of the arc coincides with the center line of the chassis 1; since several locking assemblies 4 are on the same arc, it can be ensured that the transmission belt 42 can engage with several transmission gears 43 at the same time, thereby ensuring that the transmission belt 42 can drive several transmission gears 43 and the locking screw 44 to be tightened at the same time when it is running.

[0025] like Figure 1 As shown, a grouting hole 6 is opened in the middle of the chassis 1.

[0026] like Figure 1 As shown, a plurality of evenly distributed operating components 5 are provided at the bottom of the chassis 1, and the plurality of operating components 5 are respectively distributed at the four corners of the bottom of the chassis 1; due to the provision of the plurality of operating components 5, it is convenient for the staff to operate from any side, which greatly facilitates the operation and thus helps to improve the operating efficiency.

[0027] like Figure 4As shown, the operating component 5 is movably mounted on a transmission roller 52 inside the limiting groove 41, and a transmission shaft 53 is fixedly sleeved inside the transmission roller 52. The lower end of the transmission shaft 53 passes through the transmission roller 52 and the limiting groove 41 in sequence and extends to the bottom of the chassis 1 and is fixedly connected with a control knob 51. Due to the setting of the transmission shaft 53, under the limitation of the chassis 1, it can ensure that the control knob 51 can drive the rotation of the transmission roller 52, and can effectively improve the stability of the rotation of the transmission roller 52, thereby ensuring the stability of the operation of the limiting groove 41.

[0028] like Figure 4 As shown, the upper end of the transmission shaft 53 passes through the transmission roller 52 and is connected to the top of the inner cavity of the limiting groove 41 through a bearing, and the lower end of the transmission shaft 53 is connected to the chassis 1 through a bearing.

[0029] like Figure 1 As shown, a number of evenly distributed connecting positioning holes are opened at the bottom of the main mold upright plate 2 and the side mold upright plate 3, and a number of connecting locking holes are opened inside the main mold upright plate 2 and the side mold upright plate 3; the connecting positioning holes and the connecting locking holes correspond to each other, the top of the connecting positioning hole and the bottom of the connecting locking hole are smoothly connected and interconnected, and the inner diameter of the connecting positioning hole is larger than the inner diameter of the connecting locking hole; due to the setting of the connecting positioning holes, the two main mold upright plates 2 and the side mold upright plates 3 can be conveniently placed on the top of the chassis 1 at the same time, and then with the cooperation of the locking assembly 4 and the operating assembly 5, a number of locking screws 44 can be synchronously rotated into the connecting locking holes through the connecting positioning holes, thereby greatly improving the assembly efficiency.

[0030] The working principle and use process of this utility model:

[0031] With the cooperation of the connecting positioning holes at the bottom of the main mold upright plate 2 and the side mold upright plate 3, the main mold upright plate 2 and the side mold upright plate 3 are placed on the top of the chassis 1, and then any one of the control knobs 51 can be turned to drive the corresponding transmission roller 52 to rotate through the corresponding transmission shaft 53, and then the transmission belt 42 can be stably moved with the cooperation of the remaining transmission rollers 52. Since the movement of the transmission belt 42 causes several transmission gears 43 to rotate simultaneously under the restriction of the limit groove 41, the corresponding locking screws 44 can be driven to rotate, and then the locking screws 44 are screwed into the corresponding connecting locking holes under the guidance of the connecting positioning holes, so as to quickly fix and install the main mold upright plate 2 and the side mold upright plate 3; conversely, several locking screws 44 can be screwed out, so as to quickly disassemble the main mold upright plate 2 and the side mold upright plate 3.
