[0035] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution of the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings of the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0036] The vertical spiral conveying clamp device according to the embodiment of the utility model is first described in detail below with reference to the accompanying drawings.

[0037] refer to Figure 1 and Figure 2 , Figure 1 The cross-sectional structure schematic diagram shows the vertical spiral conveying clamp device of the embodiment of the utility model in the working state. Figure 2 The schematic diagram of the structure of the vertical spiral conveying clamp device of the utility model is shown, wherein: Figure 2 (a) is the front view of the vertical spiral conveyor clamp device. Figure 2 (b) is a side view of the vertical spiral conveying clamp device.

[0038] It should be noted that in the embodiments of the present application, the first direction is used to represent the conveying direction of the screw machine, or the axial direction of the spiral tube of the screw machine. The second direction may be a perpendicular direction to the first direction. In some embodiments, the first direction and the second direction may intersect in a non-perpendicular relationship.

[0039] like Figure 1 to Figure 2As shown, according to the embodiment of the utility model, the vertical spiral conveying clamp device (hereinafter referred to as the clamp device 1000) is used to fix the screw machine 1100 on the vertical arm 1200, and the vertical arm 1200 can be regarded as a stable member connected to the ground. The clamp device 1000 includes: a clamp assembly 100, a friction assembly 200, a support flange 300 and a base plate 400. Among them, the clamp assembly 100 includes a first through hole 101 arranged along the first direction, which is used to be sleeved on the outer periphery of the screw machine 1100 (which can also be understood as a spiral tube) and clamp the screw machine 1100. Among them, the first direction is the conveying direction of the screw machine 1100. The friction assembly 200 is arranged on the inner wall of the clamp assembly 100 to increase the friction between the clamp assembly 100 and the screw machine 1100. The support flange 300 is arranged at one end of the clamp assembly 100 along the first direction, and the support flange 300 includes a second through hole 301 extending along the first direction, which is used to be sleeved on the outer periphery of the screw machine 1100. The support flange 300 is connected to the outer cylinder 1110 of the screw machine 1100 to prevent the vertical spiral of the screw machine 1100 from sinking. The base plate 400 is connected to the clamp assembly 100 and extends from the outer periphery of the clamp assembly 100 to one side of the vertical arm 1200 along the second direction. The base plate 400 is used to be connected to the vertical arm 1200.

[0040] In the embodiment of the utility model, the first direction may be perpendicular to the second direction, which makes it easier to connect the clamp device 1000 with the vertical arm 1200.

[0041] like Figure 1 and Figure 2 As shown, the clamp device 1000 can fix the screw machine 1100 on a stable vertical arm 1200 through the clamp assembly 100 and the base plate 400, and a friction assembly 200 is provided to increase the friction force, and the support flange 300 strengthens the connection with the outer cylinder 1110, which not only meets the stability of the lateral stiffness, but also effectively solves the vertical spiral sinking problem of the screw machine 1100, thereby extending the service life and reducing maintenance costs.

[0042] like Figure 1 and Figure 2As shown, in one embodiment of the utility model, the first through hole 101 may be a circular hole, and the hoop assembly 100 may include a first hoop assembly 110 and a second hoop assembly 120 that are hinged to each other, and the first hoop assembly 110 and the second hoop assembly 120 are surrounded by a full circle. In one embodiment of the utility model, the first hoop assembly 110 and the second hoop assembly 120 are semicircles, respectively, and can be interference fit (that is, the diameter of the first through hole 101 is close to or smaller than the diameter of the screw machine 1100), thereby increasing the stability of the connection between the hoop device 1000 and the screw machine 1100. In some embodiments, the first hoop assembly 110 and the second hoop assembly 120 may also not be semicircles, such as the division of 1 / 3 circle and 2 / 3 circle, and this embodiment does not make a sole limitation on this.

[0043] like Figure 2 As shown, in one embodiment of the utility model, ports 130 are extended from both ends of the first clamp assembly 110 and the second clamp assembly 120, and the first clamp assembly 110 and the second clamp assembly 120 are fixedly connected through two adjacent ports 130. This structure is more conducive to the connection of the two clamp assemblies and makes the connection more stable.

[0044] Further, in one embodiment of the present invention, the clamp device 1000 may further include a fastener, which may include a first fastener 510, and the first fastener 510 is used to connect the first clamp assembly 110 and the second clamp assembly 120. The first fastener 510 can pass through the port 130, which can not only meet the connection stability of the first clamp assembly 110 and the second clamp assembly 120, but also facilitate disassembly.

[0045] like Figure 1 and Figure 2 As shown, in one embodiment of the present invention, the fasteners may further include: a second fastener 520 and a third fastener 530. The second fastener 520 is used to connect the support flange 300 and the outer cylinder 1110. The third fastener 530 is used to connect the base plate 400 and the vertical arm 1200. In one embodiment of the present invention, the fasteners may be bolts. By providing the fasteners, the connection stability in the working state is met and the disassembly and replacement are convenient.

[0046] like Figure 2As shown, in one embodiment of the utility model, the friction assembly 200 can be a circular cylinder and fit the inner side of the clamp assembly 100. By setting the friction assembly 200 to a circular cylinder, the contact area can be maximized, thereby increasing the friction force and satisfying the stability of the lateral stiffness. In other embodiments, the friction assembly 200 can also be other shapes, for example, a long strip that fits the inner side of the clamp assembly 100, which is not the only limitation in the utility model. In some embodiments, a rough surface can be provided on the inner side wall of the friction assembly to increase the friction between the clamp assembly 100 and the screw machine 1100.

[0047] like Figure 1 As shown, in one embodiment of the present invention, the second through hole 301 is a circular hole, and the second fastener 520 fixes the support flange 300 and the outer cylinder 1110 along the outer circumference of the outer cylinder 1110. The second fasteners 520 are arranged along the outer circumference, and multiple, for example, four, five, or six, can be provided, which is not limited in the present invention.

[0048] like Figure 2 As shown, in one embodiment of the present invention, the substrate 400 surrounds the periphery of the clamp assembly 100. The substrate 400 can be bent at 270 degrees and surround the clamp assembly 100. In other embodiments, the substrate 400 can also surround the clamp assembly 100 at other angles, for example, 360 degrees, 225 degrees, 180 degrees, which is not limited in the present invention.

[0049] like Figure 2 As shown, in one embodiment of the present invention, the first fasteners 510 include at least two. In other embodiments, the first fasteners 510 may specifically include three, four, or five, which is not limited in the present invention.

[0050] like Figure 2 As shown, in one embodiment of the present invention, the third fasteners 530 include at least four. In other embodiments, the third fasteners 530 may specifically include five, six, or seven, which is not limited in the present invention.

[0051] In summary, according to the vertical screw conveying clamp device of the embodiment of the utility model, the dynamic stiffness requirements of the screw machine are met by setting a friction component, and the support flange is set to solve the problem of sinking caused by the shaking of the vertical screw during operation, thereby reducing the cost of daily maintenance and adjusting the torque of the clamp bolt. In addition, by setting multiple fasteners, the vertical screw conveying clamp device is easy to disassemble.
