[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 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.

[0019] Example 1: Please refer to Figure 1-2 The utility model provides an embodiment: a belt clamping device for a large belt conveyor, which is installed on a supporting triangular hard frame 1. The I-beam body is welded with 40# steel plate, and the I-beam is installed on the supporting triangular hard frame 1. The I-beam is directly installed on the supporting triangular hard frame 1. The device is limited by the bottom of the oblique end, which can maximize its strength.

[0020] The I-beam comprises an upper I-beam 203 and a lower I-beam 201. The lower I-beam 201 is connected to a supporting triangular hard frame 1. The lower I-beam 201 is transversely arranged on the supporting triangular hard frames 1 on the left and right sides of the belt conveyor. An upper I-beam 203 is arranged above the lower I-beam 201. A belt is arranged between the lower I-beam 201 and the upper I-beam 203. A vertically set steel platform 202 is fixedly installed on the left and right sides of the I-beam respectively. A connecting groove is opened in the steel platform 202. The upper I-beam 203 is slidably matched in the connecting groove. A top cover 204 is fixedly connected to the top of the steel platform 202. When maintenance is required, the top cover 204 is removed. 4 can be opened for maintenance. A lead screw 206 is arranged on the top cover 204. The lead screw 206 passes through the upper I-beam 203 and conflicts with the top of the lower I-beam 201. A bearing seat is arranged at the bottom of the lead screw 206. The bearing seat conflicts with the lower I-beam 201 to reduce the friction of the lead screw 206 and provide stable rotation while avoiding damage to the lead screw 206. A hand wheel 205 is arranged at the other end of the lead screw 206 to adjust the height of the upper I-beam 203. When in use, the belt is clamped by turning the hand wheel 205 to make the fastening part flexible and reduce the difficulty of personnel operation. The hand wheel 205 rotates to drive the lead screw 2 06 rotates, driving the upper I-beam 203 of the I-beam to slide up and down, and the upper I-beam 203 cooperates with the lower I-beam 201 to clamp the belt. The contact surface between the upper I-beam 203 and the lower I-beam 201 and the belt is installed with an anti-skid strip 3. The setting of the anti-skid strip 3 ensures that there is enough friction with the belt. The upper I-beam 203 and the lead screw 206 are provided with an internal thread groove for use with the lead screw 206. When the lead screw 206 rotates, due to the internal thread groove provided on the upper I-beam 203, the upper I-beam 203 moves up and down, and contacts the belt with the lower I-beam 201 at the bottom. The belt is clamped, and the upper and lower ends of the upper I-beam 203 and the lead screw 206 are both installed with limit nuts 4. After the upper I-beam 203 is clamped, the limit nuts 4 are rotated to lock the upper I-beam 203 in position, which can prevent loosening due to vibration or other reasons during the clamping process. The lower I-beam 201 is fixed to the supporting triangular frame 1 by bolts, and the steel platform 202 is fixed to the top cover 204 by bolts to increase the stability of the device and facilitate disassembly. The bolts are fixed for easy disassembly. You only need to use a wrench or a torque wrench to remove the bolts and nuts.It is convenient for maintenance and replacement. The lower I-beam 201 and the upper I-beam 203 are arranged in parallel, and the lead screw 206 is arranged vertically with the upper I-beam 203. When in use, first install the lower I-beam 201 on the belt support triangle hard frame 1 through bolts, limit the device through the bottom of the oblique end, and install the steel platform 202 and the upper I-beam 203 at the same time. The lead screw 206 is installed in conjunction with the upper I-beam 203. The bearing seat is installed at the top of the lower I-beam 201 and cooperates with the lead screw 206. When clamping the belt, turn the hand wheel 205, the lead screw 206 rotates, and drives the upper I-beam 203 to move up and down in the connecting groove. By changing the spacing between the upper I-beam 203 and the lower I-beam 201, the belt is clamped. At the same time, the upper I-beam 203 and the lower I-beam 201 and the belt contact surface are provided with anti-slip strips 3 to further increase the friction and clamp the belt.

[0021] The above is only an embodiment of the utility model, and the common sense such as the known specific structure and characteristics in the scheme is not described too much here. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the utility model.
