Description

Technical Field

[0001] The utility model relates to the field of belt conveyor testing equipment, in particular to a belt slippage rapid testing device. Background Art

[0002] There are various ways to test belt slippage in the existing technology, but the basic operating principle is to record the belt running speed, that is, when the belt is not slipping, according to the belt running power, its running speed is within a certain range. If it is lower than this range, it proves that the belt is slipping. In this case, the belt slippage test device in the existing technology is generally installed inside the belt conveyor and used as a roller. In this case, the equipment is the same as ordinary rollers, and there is also load during the operation process. Its service life will be seriously affected, and it cannot be used as a test equipment. That is, it will increase the overall manufacturing cost of the equipment, especially the high maintenance cost. Replacement is very inconvenient and requires stopping the machine for replacement. In response to the above problems, there is currently a lack of corresponding solutions. Utility Model Content

[0003] The purpose of the utility model is to overcome the shortcomings of the existing technology and provide a belt slip fast testing device which uses a belt frame as an assembly basis, enables a roller to be used for belt slip testing or continuous detection, is safe to use, and can quickly obtain test results when used for testing.

[0004] The device includes a frame, the frame includes two positioning sleeves, and a support arm is fixedly arranged between the two positioning sleeves;

[0005] A front probe arm is fixedly provided on the supporting arm, and a brake mechanism is provided on the bottom surface of the front probe arm;

[0006] The bottom surface of the support arm is hingedly provided with a roller bracket, and a roller is rotatably provided on the roller bracket. The roller is provided corresponding to the brake mechanism, and its setting direction is horizontal to the support arm;

[0007] The roller described here is a belt slip test roller with a sensor, that is, a test roller that calculates the roller's running speed by recording time and travel;

[0008] A curved rod is hingedly provided on the supporting arm, and the curved rod is connected to the roller bracket through a chain.

[0009] The effect achieved in this way is that the equipment is assembled on the belt frame with the positioning sleeve as the assembly basis, and the roller is lowered naturally. When doing the test, it is in contact with the upper belt. The roller rotates continuously for a certain period of time based on the contact with the belt. The roller is lifted to make it contact with the brake mechanism, which can achieve rapid rolling and stopping. The roller reports the test results to test whether the belt speed meets the standard; when used for long-term monitoring, the roller is in contact with the upper side of the lower belt, and the roller rotates continuously to achieve real-time monitoring, and reports the results if the speed does not meet the standard.

[0010] The beneficial effects of the present invention are as follows: the present invention solves the problems in the prior art of easy deformation and short service life of belt slip test equipment, realizes the non-load-bearing test of belt slip using auxiliary parts, and the equipment is easy to assemble and disassemble, and can be used as a long-term monitoring equipment or test equipment, thereby reducing the equipment purchase cost and maintenance cost, and having greater market promotion value.

[0014] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0015] Reference Figure 1 The utility model of a belt slippage rapid test device includes a frame, the frame includes a positioning sleeve 6, the positioning sleeve 6 has two, and a support arm is fixedly arranged between the two positioning sleeves 6;

[0016] A front probe arm 1 is fixedly provided on the support arm, and a brake mechanism 4 is provided on the bottom surface of the front probe arm 1;

[0017] The bottom surface of the support arm is hingedly provided with a roller bracket, on which a roller 5 is rotatably provided, and the roller 5 is provided corresponding to the brake mechanism 4, and its setting direction is horizontal to the support arm;

[0018] The roller 5 described here is a belt slip test roller with a sensor, that is, a test roller that calculates the roller running speed by recording time and stroke;

[0019] A curved rod 2 is hingedly provided on the supporting arm, and the curved rod 2 is connected to the roller bracket via a chain 3.

[0020] Furthermore, the signal of the roller 5 is connected to the control unit of the belt conveyor.

[0021] The effect achieved by this is that when used as a routine detection equipment, if the belt speed does not meet the standard, the result will be reported to the control unit, and the alarm or stop will be selected through the set program.

[0022] Furthermore, the positioning sleeve 6 is in the form of a square tube, and screw holes are opened on the square tube.

[0023] The effect achieved by this is that the device is fixed on the vertical frame part of the belt conveyor in the form of hard limit through the two positioning sleeves 6 and the positioning bolts.

[0024] Furthermore, the brake mechanism 4 is a rubber brake pad or an electromagnet.

[0025] Preferably, when the brake mechanism 4 is an electromagnet, the electromagnet is arranged in linkage with the crank lever 2. That is, when the crank lever 2 is lifted, the electromagnet is attracted, and when the crank lever 2 is lowered, the electromagnet is disconnected.

[0026] The effect achieved thereby is to quickly stop the rotation of the roller 5, and when the brake mechanism 4 is an electromagnet, the electromagnet is prevented from affecting the test result.

[0027] Furthermore, the curved rod 2 is bent in multiple sections and is hinged on the support arm through the lugs provided on the support arm;

[0028] There are two chains 3 in total, and the two chains 3 are respectively arranged on both sides of the roller bracket and between the curved rods 2 corresponding to the roller bracket;

[0029] And the end of the curved rod 2 is provided with a handle.

[0030] Preferably, the handle is arranged on the outside of the belt conveyor.

[0031] The effect achieved by this is to improve the safety of equipment use.

[0032] When the device is in use, it is assembled on the frame of the belt with the positioning sleeve 6 as the assembly basis, and the roller 5 is naturally lowered. When doing the test, it is in contact with the top of the upper belt. The roller 5 rotates continuously for a certain period of time based on the contact with the belt. The roller 5 is lifted to make it contact with the brake mechanism 4, which can achieve rapid rolling and stopping. The roller 5 reports the test results to test whether the belt speed meets the standard. When used for long-term monitoring, the roller 5 is in contact with the top of the lower belt and rotates continuously to achieve real-time monitoring, and reports the results when the speed does not meet the standard.
