[0002] Modular cofferdams are temporary retaining structures built in water conservancy projects to construct permanent facilities. Their main function is to prevent water and soil from entering the construction area so that drainage, excavation of foundation pits, and construction of buildings can be carried out within the cofferdam.

[0003] In order to improve the stability of existing modular cofferdams, they need to be supported by support frames. However, the support frames are quite heavy, making it difficult for workers to move them. In addition, the bottom of the support frame is prone to shifting when supporting the cofferdam, thus reducing the support effect. In order to address the above problems and defects, a new modular cofferdam support frame is needed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a modular cofferdam support frame to address the problem that existing modular cofferdams require support frames to improve their stability during use. However, the support frames are generally heavy, making them difficult for workers to move. Furthermore, the bottom of the support frame is prone to shifting when supporting the cofferdam, thus reducing the effectiveness of the support.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A modular cofferdam support frame includes: a base plate and a support plate rotatably connected to the base plate; the inner wall of the base plate has an inner cavity, a motor is fixedly mounted on the inner wall of the inner cavity, a bevel gear is fixedly mounted on the end of the output shaft of the motor, a bevel gear is meshed on the outer wall of the bevel gear, a screw is rotatably connected to the inner wall of the bevel gear, a roller is fixedly mounted on the bottom of the screw, a bevel gear is meshed on the outer wall of the bevel gear, a screw is threadedly connected to the inner wall of the bevel gear, and a fixing nail is fixedly mounted on the bottom of the screw.

[0007] Preferably, the bottom of the base plate has a through groove, the inner wall of the through groove is fixedly fitted with a second motor, the end of the output shaft of the second motor is fixedly fitted with a lead screw, the outer wall of the lead screw is threaded with a moving ring, the outer wall of the moving ring is fixedly fitted with a connecting ring, the inner wall of the connecting ring is rotatably connected with a connecting rod, the end of the connecting rod away from the connecting ring is rotatably connected with a rotating rod, the end of the rotating rod away from the connecting rod is rotatably connected with a positioning rod, and the end of the positioning rod away from the rotating rod is fixedly connected to a support plate.

[0008] Preferably, a sliding plate is fixedly mounted on the outer wall of the movable ring, and a sliding groove is formed on the inner wall of the through groove, with the sliding plate and the sliding groove being slidably connected.

[0009] Preferably, the outer wall of the fixing nail is fixedly equipped with barbs, and the number of barbs is four sets, and the four sets of barbs are evenly distributed around the periphery of the fixing nail.

[0010] Preferably, the side wall of the base plate is fixedly fitted with pull rings, and the number of pull rings is two sets.

[0013] Compared with the prior art, this utility model has at least the following beneficial effects:

[0014] 1. In the above scheme, the bottom of the base plate is pulled up by the pull ring, and the position of the device can be changed by the roller at the end of the base plate. After the support of the cofferdam is completed, the first motor drives the first bevel gear to rotate. The rotation of the first bevel gear drives the second bevel gear and the first screw to rotate. The rotation of the first screw drives the roller to move upward. At the same time, the rotation of the first bevel gear drives the third bevel gear to rotate, which in turn drives the second screw and the fixing nail to move towards the contact surface until the fixing nail is inserted into the contact surface. When the first motor reverses, the fixing nail can be retracted and the roller can be moved outside the base plate. This helps to improve the convenience of moving the device and improve the friction of the device, thus ensuring the support effect of the cofferdam.

[0015] 2. In the above scheme, the screw is driven by the second motor to rotate. The rotation of the screw causes the moving ring and the connecting ring to move laterally. The movement of the connecting ring causes the connecting rod and the rotating rod to rotate. Finally, the rotation of the rotating rod pushes the positioning rod and the support plate to adjust their angles. This helps to improve the adaptability of the device and improve the stability when supporting the cofferdam. Attached Figure Description

Detailed Implementation

[0026] The modular cofferdam support frame provided by this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are listed as best and preferred embodiments, and other alternative methods may be used by those skilled in the art; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0027] like Figure 1 , Figure 3 and Figure 5As shown, an embodiment of this utility model provides a modular cofferdam support frame, including: a base plate 1, and a support plate 2 rotatably connected to the base plate 1; the inner wall of the base plate 1 has an inner cavity 111, and a motor 112 providing driving force is fixedly mounted on the inner wall of the inner cavity 111. A bevel gear 113 is fixedly mounted at the end of the output shaft of the motor 112. A bevel gear 114 meshes with the outer wall of the bevel gear 113. A screw 115 is rotatably connected to the inner wall of the bevel gear 114. A roller 116 is fixedly mounted at the bottom of the screw 115. A rectangular limiting block is provided between the screw 115 and the roller 116. A bevel gear 117 meshes with the outer wall of the bevel gear 114. The inner wall of wheel 117 is threaded with screw 118. Screw 115 has the opposite thread to screw 118. Screw 118 is fixedly fitted with a fixing nail 119 at its bottom. A rectangular limiting block is provided between screw 118 and fixing nail 119. The bottom of the base plate 1 is provided with a matching groove that matches the roller 116 and fixing nail 119. The outer wall of fixing nail 119 is fixedly fitted with barbs 120. There are four sets of barbs 120, and the four sets of barbs 120 are evenly distributed around the fixing nail 119. By setting four sets of evenly distributed barbs 120, it is beneficial to improve the friction between fixing nail 119 and the contact surface, thereby preventing the base plate 1 from shifting during use.

[0028] like Figure 2 and Figure 4 As shown, a through groove 101 is provided at the bottom of the base plate 1. A second motor 102 is fixedly mounted on the inner wall of the through groove 101. A lead screw 103 is fixedly mounted at the end of the output shaft of the second motor 102. A moving ring 104 is threadedly connected to the outer wall of the lead screw 103. A connecting ring 105 is fixedly mounted on the outer wall of the moving ring 104. A connecting rod 106 is rotatably connected to the inner wall of the connecting ring 105. A rotating rod 107 is rotatably connected to the end of the connecting rod 106 away from the connecting ring 105. A rotating rod 107 is rotatably connected to the end of the rotating rod 107 away from the connecting rod 106. The positioning rod 108 is fixedly connected to the support plate 2 at one end away from the rotating rod 107. The lead screw 103 is driven to rotate by the motor 102. The rotation of the lead screw 103 causes the moving ring 104 and the connecting ring 105 to move laterally. The movement of the connecting ring 105 causes the connecting rod 106 and the rotating rod 107 to rotate. Finally, the rotation of the rotating rod 107 pushes the positioning rod 108 to adjust the angle between itself and the support plate 2. This helps to improve the adaptability of the device and the stability when supporting the cofferdam.

[0029] like Figure 2 and Figure 4As shown, a sliding plate 109 is fixedly mounted on the outer wall of the moving ring 104, and a sliding groove 110 is provided on the inner wall of the through groove 101. The sliding plate 109 and the sliding groove 110 are slidably connected. By setting the sliding plate 109 and the sliding groove 110, it is beneficial to provide stability when the moving ring 104 moves, thereby improving the stability of the rotating rod 107 and the support plate 2 during use.

[0030] like Figure 1 As shown, the side wall of the base plate 1 is fixedly equipped with pull rings 121. There are two sets of pull rings 121. By setting pull rings 121, it is convenient to change the position of the device by using pull rings 121 in conjunction with rollers 116.

[0031] like Figure 1 and Figure 3 As shown, an anti-slip pad 122 is fixedly mounted on the bottom of the base plate 1. The bottom of the anti-slip pad 122 has a groove 123. By setting the anti-slip pad 122 and the groove 123, it is beneficial to improve the friction between the base plate 1 and the contact surface and improve its stability during use.

[0032] like Figure 3 and Figure 5 As shown, there are two sets of components: motor 112, bevel gear 113, bevel gear 2 114, screw 115, roller 116, bevel gear 3 117, screw 2 118, and fixing pin 119. These components are symmetrically distributed on both sides of the bottom of the base plate 1. By limiting the number and position of these components, the device can be moved more easily and supported more stably.

[0033] The technical solution provided by this utility model allows the bottom of the base plate 1 to be pulled up by the pull ring 121 during operation. The position of the device can be changed by the roller 116 at the end of the base plate 1. After the support of the cofferdam is completed, the bevel gear 113 is driven to rotate by the motor 112. The rotation of the bevel gear 113 drives the bevel gear 114 and the screw 115 to rotate. The rotation of the screw 115 drives the roller 116 to move upward. At the same time, the rotation of the bevel gear 113 drives the bevel gear 117 to rotate, which in turn drives the screw 118 and the fixing nail 119 to move towards the contact surface until the fixing nail 119 is inserted into the contact surface. When the motor 112 reverses, the fixing nail 119 can be retracted and the roller 116 can be moved outside the base plate 1, which helps to improve the convenience of moving the device.

[0034] The screw 103 is driven to rotate by the motor 102. The rotation of the screw 103 causes the moving ring 104 and the connecting ring 105 to move laterally. The movement of the connecting ring 105 causes the connecting rod 106 and the rotating rod 107 to rotate. Finally, the rotation of the rotating rod 107 pushes the positioning rod 108 to adjust the angle between it and the support plate 2. This helps to improve the adaptability of the device and enhance the stability of the cofferdam support.

[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
