Abstract
Description
Technical Field
[0001] The utility model belongs to the field of pellet chain grate maintenance and replacement technology, and in particular relates to a device for quickly replacing a grate bed of a chain grate. Background Art
[0002] Since the chain grate machine is produced and operated in a high temperature environment for a long time, the high temperature environment has a great damage to the grate bed of the entire chain grate machine, and the grate bed is easy to burn. The difficulty in replacing the chain grate machine grate bed as a whole or in part is how to pull and adjust the grate bed position. The existing technology is to pull the grate bed through a winch, and then use a jack to adjust it according to the offset of the grate bed. Since the grate bed is long, it is easy to cause the grate bed pin shaft to deform and the grate bed to deviate to one side during the pulling process, which makes it more difficult to adjust and connect the grate bed and repeats ineffective labor.
[0003] At present, the chain grate machine is replaced by connecting two winches to the grate bed in a separate way, and then starting the winches to pull the grate bed. Ideally, the two winches need to be started synchronously, but the actual operation is more difficult, which often causes the grate bed to shift to the slow-starting side during pulling. After the shift, it needs to be adjusted immediately, resulting in frequent adjustments, extremely labor-intensive construction, and a long replacement time. Utility Model Content
[0004] The utility model aims to provide a device for quickly replacing the grate bed of a chain grate machine.
[0005] The technical solution adopted by the utility model to solve its technical problems is: a device for quickly replacing a grate bed of a chain grate machine, comprising a grate bed, adjustment mechanisms are provided on both sides of the grate bed, the adjustment mechanism is provided with a first movable push plate, the first end of the first movable push plate is opposite to the grate bed, the second end of the first movable push plate is provided with a sensing contact, the second end of the first movable push plate is opposite to a second movable push plate, the second movable push plate is connected to an electric hydraulic push rod, a displacement signal is transmitted to a controller through the sensing contact, and the controller controls the electric hydraulic push rod to move to correct the grate bed.
[0006] Specifically, a grate bed hoisting tool is installed on the grate bed, and a lifting ring is provided on the top of the grate bed hoisting tool.
[0007] Specifically, a hook is installed on the lifting ring, and the hook is connected to the winch through a wire rope.
[0008] Specifically, a pulley is provided on the trajectory of the steel wire rope movement.
[0009] Specifically, the first movable push plate and the second movable push plate are installed on a bottom plate with a slide groove.
[0010] The utility model has the following beneficial effects:
[0011] 1) During the process of pulling the grate bed, two automatic adjustment devices are used to detect the running track of the grate bed in real time. When the grate bed deviates, the grate bed can be automatically corrected, thus realizing the normal and stable pulling of the grate bed;
[0012] 2) It can effectively reduce labor intensity, shorten replacement time, and improve operation safety and efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
[0013] Figure 1 It is a structural schematic diagram of the utility model.
[0014] In the figure: 1-grate bed; 2-first movable push plate; 3-inductive contact; 4-electric hydraulic push rod; 5-hoisting grate bed tooling; 6-hook; 7-pulley; 8-winch; 9-second movable push plate. DETAILED DESCRIPTION
[0015] The utility model will now be further described in detail with reference to the accompanying drawings.
[0016] like Figure 1 As shown, a device for quickly replacing a grate bed of a chain grate machine comprises a grate bed 1. Adjustment mechanisms are provided on both sides of the grate bed 1. The adjustment mechanisms are provided with a first movable push plate 2. The first end of the first movable push plate 2 is opposite to the grate bed 1. The second end of the first movable push plate 2 is provided with a sensing contact 3. The second end of the first movable push plate 2 is opposite to a second movable push plate 9. The second movable push plate 9 is connected to an electric hydraulic push rod 4. The displacement signal is transmitted to the controller through the sensing contact 3. The controller controls the electric hydraulic push rod 4 to move to correct the grate bed.
[0017] A grate bed hoisting tool 5 is installed on the grate bed 1. A lifting ring is provided on the top of the grate bed hoisting tool 5. A hook 6 is installed on the lifting ring. The hook 6 is connected to a winch 8 through a wire rope. A pulley 7 is provided on the trajectory of the wire rope movement.
[0018] The use of the utility model:
[0019] The time for replacing the grate bed 1 of the chain grate machine is shortened, and the grate bed 1 is prevented from being deformed during transportation and can realize automatic adjustment of the offset of the chain grate machine grate bed 1. There are two adjustment mechanisms for relative positions, and sensing contacts 3 are respectively arranged on the opposite sides of the two adjustment mechanisms. When the grate bed 1 is offset, the first movable push rod 2 on one side is moved, and the distance between the first movable push rod 2 and the second movable push rod 9 is changed, so that the sensing contact 3 transmits the displacement signal to the controller, and the controller controls the electric hydraulic push rod 4 to move, thereby pushing the second movable push rod 9, and then pushing the first movable push rod 2. The first movable push rod 2 corrects the grate bed 1. After the grate bed 1 is corrected, the electric hydraulic push rod 4 is recovered, so that the distance between the first movable push rod 2 and the second movable push rod 9 is restored to its original state.
