DETAILED DESCRIPTION

[0018] 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 the best embodiments of the utility model, not all 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.

[0019] This embodiment provides a non-destructive installation fixture for an electric wheel 5, which, as an installation module for an electric wheel 5, can adapt to different installation requirements of various installation scenarios. According to the common characteristics of the products to be modified commonly used for mobile automation modification of the electric wheel 5, such as shelves, tables and chairs, and door frames, these products to be modified all have a reinforcing crossbeam 11 structure at the bottom as the original support foot 4. Therefore, the electric wheel 5 uses the crossbeam 11 as the installation support for automation improvement. This embodiment takes the automation improvement of the original non-automatic door as an example to explain the structure and installation method of the fixture assembly 6;

[0020] like Figure 1 As shown, the original non-automatic door includes a fixed door 2, a movable door 1 and a support foot 4. The fixed door 2 and the movable door 1 are connected by a hinge 3. The support foot 4 under the original movable door 1 is improved into an electric wheel 5 support foot 4. The electric wheel 5 can be remotely controlled to realize the automatic door opening and locking functions. Therefore, the electric wheel 5 can be non-destructively installed by clamping the crossbeam 11 at the lower end of the movable door 1 through the clamp assembly 6;

[0021] like Figure 1-Figure 4As shown, the clamp assembly 6 is a detachable modular assembly, which can be adapted to various structural dimensions of the beam 11, and includes a first clamping body 610, a second clamping body 620 and a height adjustment screw 640. The first clamping body 610 and the second clamping body 620 have the same structural dimensions and are in a C-shaped structure. The two clamping bodies are relatively fastened to press the beam 11 therein, and both include an upper clamping plate, a side clamping plate and a lower clamping plate. The upper clamping plate and the lower clamping plate are penetrated with a plurality of connecting holes 612 perpendicular to the beam 11, wherein The connection hole 612 on the first clamping body 610 is a step hole, and the connection hole 612 on the second clamping body 620 is a threaded hole. In this way, the first clamping body 610 and the second clamping body 620 cover the middle crossbeam 11 from both sides of the crossbeam 11, and the step hole and the threaded hole are connected in series by bolts, so that the first clamping body 610 and the second clamping body 620 relatively clamp the middle crossbeam 11, and the inner side surface 614 of the side clamping plate presses the side surface of the crossbeam 11 and applies a lateral clamping force, completing the preliminary installation of the installation fixture;

[0022] Since the height of the electric wheel 5 is fixed, in order to adapt to different installation heights, a plurality of first adjustment screw holes 613 are evenly arranged on the lower clamping plate, and a corresponding number of height adjustment screws 640 are respectively threadedly positioned in the first adjustment screw holes 613, and the ends of the height adjustment screws 640 touch the lower plane of the crossbeam 11. By adjusting the height of the ends of the height adjustment screws 640 extending out of the lower clamping plate, the height of the lower clamping plate from the ground is adjusted according to the height of the supporting feet 4 to adapt to the installation height of the electric wheel 5. In addition, the height adjustment screws 640 can also provide vertical support force, thereby completing the support installation of the installation fixture;

[0023] In order to completely limit the vertical position to lock the height position of the beam 11, the first clamping body 610 and the second clamping body 620, the clamp assembly 6 also includes a plurality of height fixing screws 630, and a corresponding number of second adjusting screw holes 611 are evenly arranged on the upper clamping plate. Of course, the positions of the height fixing screws 630 and the height adjusting screws 640 can correspond to each other up and down, so as to reduce the flexural deformation of the beam 11. The height fixing screws 630 are threadedly connected with the second adjusting screw holes 611, and the lower end thereof extends out of the second adjusting screw holes 611 and contacts the upper plane of the beam 11, and cooperates with the height adjusting screws 640 to apply a vertical clamping force to the beam 11;

[0024] Finally, by installing bolts to connect the mounting holes 511 on the mounting plate 51 of the electric wheel 5 and the mounting screw holes on the lower clamping plate, the detachable installation of the electric wheel 5 is realized; the movable door 1 of the original non-automatic door can realize the automatic opening and closing actions around the hinge 3 under the support of the electric wheel 5.

[0025] As a further technical solution of this exemplary embodiment, refer again to Figure 2-Figure 4The number of height adjustment screws 640 and height setting screws 630 is at least four, and they should be arranged in a dot matrix evenly distributed manner. During installation, they should be tightened one by one in multiple steps, and the horizontality of the first clamping body 610 and the second clamping body 620 should be ensured. In order to increase the contact area with the surface of the beam 11, a pad 641 is fixed at the lower end of the height adjustment screw 640 and the height setting screw 630.

[0026] As a further technical solution of this exemplary embodiment, due to the different widths of the cross beam 11, there are gaps of different sizes between the first clamping body 610 and the second clamping body 620, which makes it difficult to locate the positions of the two and install the series bolts. In addition, the lateral shear force during use acts on the series bolts, which easily causes deformation and makes disassembly difficult. Therefore, by setting the tenon and the tenon groove for positioning and structural reinforcement, refer again to Figure 2 , wherein the upper and lower plates of the first clamping body 610 are provided with plug-in tenons 615 on the opposite sides, and the upper and lower plates of the second clamping body 620 are provided with plug-in tenons 621 on the opposite sides. The plug-in tenons 615 and the plug-in tenons 621 are plugged in with each other. Regardless of the installation width of the beam 11, the plug-in tenons 615 can be inserted into the plug-in tenons 621 for quick positioning and to improve the overall shear strength of the clamp assembly 6.

[0027] As a further technical solution of this exemplary embodiment, a monitoring unit is also provided on the clamp assembly 6 for giving an alarm when the clamping strength is insufficient, such as Figure 3 As shown, the monitoring unit includes a strain sensor 650 and a digital display alarm 660. There are two strain sensors 650, which are vertically attached to the outer surface of the side clamp of the first clamping body 610 and are respectively located near the serial screws to collect strain data at the optimal deformation monitoring positions at the upper and lower ends of the first clamping body 610. The digital display alarm 660 can display the strain data and preset the strain alarm low value. The strain data signal is fed back to the digital display alarm 660. When the strain value is lower than the preset strain alarm low value, a sound or light warning is issued.
