[0030] Protective assembly 3 includes protective lower cover 31 and protective upper cover 32, protective lower cover 31 is installed on the top of installation base 1, protective upper cover 32 is detachably installed on the top of protective lower cover 31, and observation lower hole 37 and observation upper hole 38 are respectively formed in the front wall of protective lower cover 31 and protective upper cover 32.
[0031] Dustproof assembly 5 is installed on the inner wall of protective upper cover 32, and the dustproof end of dustproof assembly 5 is arranged at observation lower hole 37 and observation upper hole 38, and fan 4 is installed on the inner wall of protective lower cover 31.
[0032] Specifically, protective assembly 3 is installed on installation base 1 to provide dust protection. Protective upper cover 32 is detachably installed on protective lower cover 31, which facilitates the maintenance or replacement of tractor 2.
[0033] Observation lower hole 37 and observation upper hole 38 are reserved on protective upper cover 32 and protective lower cover 31, so that the operator can observe the specific situation of tractor 2 inside the protective cover (protective upper cover 32 and protective lower cover 31) from the outside. The dustproof assembly 5 can shield the position of the observation hole (observation lower hole 37 and observation upper hole 38), so as to prevent dust from entering the inside of the protective cover and adhering to the tractor 2 and the traction rope.
[0034] The air outlet of the fan 4 is opposite the hoisting rope of the hoisting machine 2, and the control system of the fan 4 is connected with the control system of the hoisting machine 2. When the hoisting machine 2 works, the fan 4 is started synchronously to blow the dust adhered to the hoisting rope from the outside, so as to avoid the dust from gathering on the hoisting machine 2.
[0035] Further, the bottom of the upper protective cover 32 is fixedly connected with a mounting plate 36, the top of the lower protective cover 31 is provided with a mounting groove 35, and the upper protective cover 32 is inserted into the mounting groove 35 through the mounting plate 36 to be placed on the lower protective cover 31.
[0036] Specifically, the mounting plate 36 and the mounting groove 35 are arranged to enable the upper protective cover 32 to be accurately mounted on the lower protective cover 31, so as to avoid misalignment between the two during installation and leave a gap for dust to enter.
[0037] Further, the left and right side walls of the lower protective cover 31 are fixedly connected with mounting lower plates 33, and the left and right side walls of the upper protective cover 32 are fixedly connected with mounting upper plates 34. The mounting upper plates 34 and the mounting lower plates 33 are detachably mounted through bolts.
[0038] Specifically, the upper protective cover 32 is detachably mounted on the lower protective cover 31 through the bolts between the mounting upper plates 34 and the mounting lower plates 33, which facilitates the removal of the upper protective cover 32 when the hoisting machine 2 is maintained or replaced.
[0039] Further, the dustproof assembly 5 comprises an L-shaped block 51 and a mounting block 52. The L-shaped block 51 and the mounting block 52 are fixedly connected to the inner wall of the upper protective cover 32. A rotating rod 53 is rotatably mounted between the L-shaped block 51 and the mounting block 52. One end of the rotating rod 53 penetrates the side wall of the L-shaped block 51 and is connected to the output shaft end of a motor 54. A dust cloth 55 is wound around the side wall of the rotating rod 53.
[0040] Specifically, one end of the rotating rod 53 is rotatably mounted in the mounting block 52, and the other end penetrates the side wall of the L-shaped block 51 and is connected to the output shaft end of the motor 54. The motor 54 is mounted on the L-shaped block 51.
[0041] One end of the dust cloth 55 is fixedly connected to the side wall of the rotating rod 53, and the other end is fixedly connected with an iron block 56. When the motor 54 controls the rotating rod 53 to rotate, the dust cloth 55 can be wound.
[0042] Further, the movable end of the dust cloth 55 is fixedly connected with the iron block 56. The left and right side walls of the observation lower hole 37 and the observation upper hole 38 are provided with moving grooves 6. The two ends of the iron block 56 are movably arranged in the moving grooves 6. The top of the mounting base 1 is fixedly connected with a magnet 9.
[0043] Specific is, two ends of the iron block 56 are clamped in the moving slot 6, so that the iron block 56 can always shield the observation hole and cannot cause a gap due to dislocation caused by wind blowing. The setting of the magnet 9, when the iron block 56 moves to the magnet 9, the iron block 56 is attracted by the magnetic force of the magnet 9 to close the observation hole.
[0044] Further, the control button one 7 and the control button two 8 are respectively installed on the inner top and the inner bottom of the installation slot 35 close to the motor 54, and the control button one 7 and the control button two 8 are connected with the motor 54 through lines.
[0045] Specifically, when the dust cloth 55 is rolled up under the rotation of the rotating rod 53, the iron block 56 can control the motor 54 to stop working when pressing the control button one 7, so that the rotating rod 53 stops rolling the dust cloth 55, and at this time the observation hole is opened. When the dust cloth 55 is protected, the iron block 56 can also control the motor 54 to stop working when pressing the control button two 8 due to the magnetic force of the magnet 9, and at this time the observation hole is shielded.
[0046] It should be noted that the fan 4 and the motor 54 are connected with the power supply system of the traction machine 2 for power supply. The protective upper cover 32 is provided with a button to control the start and stop of the motor 54.
[0047] The working principle and use process of the utility model: after the utility model is installed, when it is necessary to prevent dust on the traction machine 2, the dust cloth 55 is lowered, that is, the motor 54 controls the rotating rod 53 to rotate and makes the dust cloth 55 drive the iron block 56 to move downward, until the iron block 56 is attracted by the magnet 9 and presses the control button two 8, at this time the motor 54 stops working, the observation hole is shielded by the dust cloth 55, and the whole upper part of the traction machine 2 is shielded.
[0048] When it is necessary to observe the traction machine 2 to decide whether it is necessary to maintain, the motor 54 controls the rotating rod 53 to rotate and makes the dust cloth 55 drive the iron block 56 to move upward along the moving slot 6, until the iron block 56 presses the control button one 7, at this time the motor 54 stops working, and the observation hole is opened.
[0049] When it is necessary to maintain the traction machine 2, the operator can take down the bolts on the installation upper plate 34 and the installation lower plate 33, so that the protective upper cover 32 can be taken down from the protective lower cover 31, which is convenient and fast.
[0050] In addition, when the traction machine 2 works, the fan 4 is started synchronously to blow the dust adhered on the traction rope from the outside, so as to avoid that the dust is accumulated on the traction machine 2.
[0051] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
