Description

Technical Field

[0001] This utility model relates to the field of conveying equipment, and in particular to a cross-arm roller mounting device. Background Technology

[0002] Currently, the installation of rollers in roller conveyor equipment is mainly carried out manually. The power transmission between rollers is mainly transmitted through the friction of the multi-wedge belt. During roller installation, the rollers are often resisted by the elasticity of the multi-wedge belt itself. After a certain number of installations, it is also a great test of the physical strength of the installation workers, which in turn affects the installation progress and efficiency of the roller conveyor equipment. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a cross-arm roller mounting device, which uses a threaded push method to allow the roller frame on the cross push arm to cover different roller center distances. It has a simple structure, is easy to operate, and reduces reliance on manual labor.

[0004] According to one aspect of the present invention, a crossarm roller mounting device is provided, comprising: A screw push rod, wherein the screw push rod is vertically arranged and has a wrench at the top; A threaded bracket, wherein the threaded bracket is fixedly installed and its middle portion is sleeved on the screw push rod; Two cross push arms, each cross push arm comprising two arms and a roller frame, the two ends of the roller frame being respectively mounted on the bottom ends of the two arms, and the top ends of the two arms of each cross push arm being movably connected to both sides of the threaded bracket; Two fixing blocks are connected to each other, and the bottom of the screw push rod is clamped between the two fixing blocks; Two push plates, one end of which is hinged to the two fixed blocks, and the other end of which is hinged to the two roller frames.

[0005] In some embodiments, the wrench head is hexagonal. Its advantage is that the wrench head can be turned using a corresponding socket or open-end wrench, or optionally an electric wrench, causing the screw push rod to rotate around its central axis, thereby driving other related structures.

[0006] In some embodiments, the threaded bracket has a threaded hole in the middle, which is fitted onto the screw push rod. The advantage is that it describes the specific related structure of the threaded bracket fitted onto the screw push rod.

[0007] In some embodiments, the threaded bracket has two crossbars on each side, and the top ends of the two arms of each of the cross push arms are movably connected to the two crossbars. The advantage is that it describes the specific related structure of the top ends of the arms of each cross push arm being movably connected to each threaded bracket.

[0008] In some embodiments, nuts are installed at the ends of both crossbars. This is advantageous because the nuts prevent the arms of the crossbars from slipping off the ends of the crossbars.

[0009] In some embodiments, the cross push arms are covered with a scratch-resistant material. This is advantageous because it prevents tools from scratching the outer surface of the rollers during installation, protecting the aesthetics of the roller conveyor. Attached Figure Description

[0012] The present invention will now be described in further detail with reference to the accompanying drawings.

[0013] like Figure 1-4 As shown, the device mainly includes a screw push rod 1, a threaded bracket 2, two cross push arms 3, two fixing blocks 4, and two push plates 5.

[0014] The screw push rod 1 is set vertically, and its top end has a hexagonal rod head. The wrench head 11 can be turned by the corresponding socket or open wrench, or an electric wrench can be used to turn the wrench head 11, so that the screw push rod 1 rotates around its own central axis, thereby driving other related structures to operate.

[0015] The threaded bracket 2 is fixedly installed and fitted onto the screw push rod 1 in the middle. The threaded bracket 2 has a threaded hole 21 in the middle, which fits onto the screw push rod 1. Two horizontally extending crossbars 22 are located on each side of the threaded bracket 2. Due to the presence of the threaded bracket 2, rotating the screw push rod 1 allows it to move up and down axially.

[0016] Each cross pusher arm 3 includes two arms 31 and a roller frame 32, with both ends of the roller frame 32 respectively mounted on the bottom ends of the two arms 31. The top ends of the two arms 31 of each cross pusher arm 3 are movably connected to two crossbars 22, and the top ends of the arms 31 on the same side of the two cross pusher arms 3 are movably connected to the same crossbar 22. In other words, the top ends of the arms 31 on both sides of each cross pusher arm 3 are movably connected to the two crossbars 22.

[0017] Preferably, nuts 23 are installed at the ends of both crossbars 22 to prevent the arm 31 of each cross push arm 3 from slipping off the end of the crossbar 22.

[0018] Preferably, the cross push arm 3 is covered with a felt-like anti-scratch material, which can prevent tools from scratching the outer surface of the roller during installation and protect the aesthetics of the roller conveyor equipment.

[0019] The two fixed blocks 4 are connected to each other, and the bottom of the screw push rod 1 is sandwiched between the two fixed blocks 4, so the two fixed blocks 4 can rise and fall with the bottom of the screw push rod 1.

[0020] One end of each of the two push plates 5 is hinged to one of the two fixed blocks 4, and the other end is hinged to the roller frame 32 of the two cross push arms 3. When the screw push rod 1 rises and falls, it can rotate the two cross push arms 3 and the roller frame 32 on them about the cross bar 22 as the central axis through the two fixed blocks 4 and the two push plates 5.

[0021] In use, the device is placed on the roller conveyor 6, with the roller frames 32 of the two cross push arms 3 supporting the two rollers 7 on the roller conveyor 6. Turning the wrench 11 rotates and raises the screw push rod 1, causing the two cross push arms 3 and their roller frames 32 to rotate around the crossbar 22 as the central axis, thus moving the rollers for easy installation. By using a threaded mechanism to move the two cross push arms 3, the center distance distribution of the roller frames 32 on the two cross push arms 3 can be more precise, covering different roller center distances, and is more convenient and less prone to errors.

[0022] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
