Description

Technical Field

[0001] The utility model relates to a smoke protection test device for a belt conveyor, belonging to the technical field of coal mine conveying safety protection equipment. Background Art

[0002] Inside coal mine conveyor tunnels, smoke alarms are fixedly installed at the top of the tunnel above the belt to detect smoke inside the tunnel. During daily operations, smoke alarms need to be tested regularly to ensure they function properly when smoke is generated inside the tunnel. Traditionally, the belt is stopped and a worker stands on it to perform the test. This approach not only requires stopping the belt, which affects production efficiency, but also requires workers to stand on the belt to operate it, which is cumbersome and poses certain safety risks when working at height. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a smoke protection test device for a belt conveyor to solve the technical problems existing in the above-mentioned prior art.

[0004] The technical solution adopted by the utility model is: a belt conveyor smoke protection test device, comprising a fixed column vertically fixed on a belt frame, a fixed pulley installed on the top of the fixed column; a capstan is installed at the bottom of the fixed column, and the rope of the capstan passes through the fixed pulley and is connected to the smoke alarm.

[0005] Preferably, the smoke alarm is installed inside a hanging basket, and the hanging basket is in the shape of a rectangular parallelepiped with an open top.

[0006] Preferably, the hanging basket is a stainless steel mesh basket.

[0007] Preferably, the fixed column is provided with a T-shaped slide groove arranged in the vertical direction, and a T-shaped block cooperating with the T-shaped slide groove is fixed on the outer wall of the hanging basket. The T-shaped block is inserted into the T-shaped slide groove and can only slide up and down along the T-shaped slide groove.

[0008] Preferably, the number of the card blocks is set to be more than 2 and they are aligned up and down.

[0009] Preferably, the fixing column is a steel column.

[0010] Preferably, the rope is an oil wire rope.

[0011] Beneficial effects of the utility model:

[0012] Compared with the prior art, in the utility model, a worker standing on the ground can lower the smoke alarm by turning the handle of the winch drum, which is convenient for testing the smoke alarm without stopping the belt, thereby improving work efficiency; after the test is completed, the smoke alarm can be raised by turning the handle of the winch drum in the opposite direction; the operation is convenient, and the danger of sudden starting of the belt during the test is avoided, the safety is high, and the protection test is safer, more reliable and more practical.

[0013] In the utility model, the smoke alarm is placed in the hanging basket, which plays a protective role for the smoke alarm and prevents the smoke alarm from being damaged; the hanging basket is set as a mesh basket to prevent the hanging basket from affecting the sensitivity of the smoke alarm; the top of the hanging basket is set as an opening, which is convenient for installing and removing the smoke alarm and facilitating the inspection and replacement of the smoke alarm.

[0014] In the utility model, the clamping block cooperates with the slide groove to ensure that the hanging basket and the smoke alarm are lifted up and down vertically, thereby preventing the smoke alarm from rotating or shaking during the lifting process and damaging the smoke alarm. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 It is a schematic diagram of the overall structure of the utility model.

[0016] The reference numerals in the drawings of the specification include: fixed column 1, slide 2, fixed pulley 3, rope 4, hanging basket 5, smoke alarm 6, clamping block 7, and winch drum 8. DETAILED DESCRIPTION

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Example

[0018] Belt conveyor smoke protection test device, such as Figure 1 As shown, it includes a fixed column 1 vertically fixed on the belt frame, the fixed column 1 is a steel column, a fixed pulley 3 is installed on the top of the fixed column 1 through a mounting plate, the axis of the fixed pulley 3 is arranged in the horizontal direction, and a winch drum 8 is installed at the lower part of the fixed column 1. The rope 4 of the winch drum 8 passes upward through the fixed pulley 3 and is tied with a hanging basket 5. The hanging basket 5 is a rectangular stainless steel mesh basket with an open top. The smoke alarm 6 is installed inside the hanging basket 5, and the rope 4 is an oil wire rope.
