The utility model discloses a one-way electric chain hoist which comprises a chain wheel carrier, a chain wheel, a chain assembly, a motor, a gear speed reduction case and a limiting mechanism. The chain of the chain assembly is in hung connection with the chain wheel, two ends of the chain assembly are respectively connected with a hook and a bumping block, and upper and lower limit positions of the hook are controlled by the limiting mechanism. The one-way electric chain hoist is characterized in that the chain wheel is rotatably arranged between left and right support plates of the chain wheel carrier, the motor is a near magnetic braking motor, and the near magnetic braking motor and the gear speed reduction case are respectively arranged on the left and right sides of the chain wheel carrier. The limiting mechanism comprises a limiting plate, a warping plate, a limiting switch shaft and a limiting switch. The one-way electric chain hoist is simple and compact in structure and adopts the warping plate type limiting mechanism to achieve ascending and descending limiting.
Description
Technical field
The utility model relates to a kind of improvement invention of unidirectional Electric Chain Blocks.
background technology
Electric block mainly contains two kinds of steel-wire rope type electric block and Electric Chain Blocks, and Electric Chain Blocks is gained the name because its lifting adopts chain.The main deficiency of existing Electric Chain Blocks has: the monnolithic case size after motor, drop-gear box and sprocket wheel are arranged is large, and drop-gear box generally adopts planetary reduction gear, and structure is not compact; The upper and lower spacing common employing roof pressing type structure of stop gear, structure relative complex, and also upper and lower spacing action neither be very reliable; Unidirectional Electric Chain Blocks adopts drg to brake conventionally in addition, and structure relative complex also needs further to be improved.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of simple and compact for structure, adopts moving seesaw-type stop gear to realize electric block and rises and decline pair spacing unidirectional Electric Chain Blocks.
The utility model is implemented by following technical solution:
Unidirectional Electric Chain Blocks, comprise sprocket holder, sprocket wheel, chain assemblies, motor, gear reduction box and stop gear, the chain of chain assemblies is articulated on sprocket wheel, the two ends of chain assemblies are connecting shackle and collision block respectively, the bound position of suspension hook is controlled by stop gear, it is characterized in that: sprocket wheel rotates setting between the supporting plate of the left and right of sprocket holder, motor adopts and is close to magnetic brake motor, is close to magnetic brake motor and gear reduction box and is respectively in the left and right sides of sprocket holder.
The unidirectional Electric Chain Blocks of technique scheme, drop-gear box adopts gear reduction, motor adopts and is close to magnetic brake motor, be close to the left and right sides that magnetic brake motor and gear reduction box are respectively in sprocket holder, first above-mentioned design makes the structure of electric block very compact, be close to magnetic brake motor simultaneously and carry braking function, so electric block does not need to arrange in addition drg, simplified structure.
As preferably, stop gear comprises positioning plate, seesaw, limit switch axle and limit switch, positioning plate is provided with left and right through hole and passes respectively by the chain two ends of connecting shackle and collision block, positioning plate swings setting below sprocket wheel, positioning plate drives seesaw to carry out left and right by oscillating axle while swing and upwarps action, limit switch axle is provided with two of left and right, vertical movable setting of left and right limit switch axle, the lower end of left and right limit switch axle is resisted against respectively on the left and right of seesaw on warping, limit switch is provided with two of left and right above the limit switch axle of left and right, the contact of left and right limit switch and left and right limit switch axle upper rectify right.
Adopt after technique scheme, stop gear realizes electric block rising with moving seesaw-type manner of execution and decline is two spacing, simple in structure, upper and lower spacing reliable in action.
Accompanying drawing explanation
The utility model has following accompanying drawing:
Fig. 1 is shape assumption diagram of the present utility model,
Fig. 2 is the right elevation of Fig. 1,
Fig. 3 is the left view of Fig. 1.
The specific embodiment
Describe details and the principle of work of the utility model specific embodiment in detail below in conjunction with accompanying drawing:
As shown in the figure, unidirectional Electric Chain Blocks of the present utility model, comprise sprocket holder 2, sprocket wheel, chain assemblies, motor 3, gear reduction box 1 and stop gear, the chain 5 of chain assemblies is articulated on sprocket wheel, the two ends of chain assemblies are connecting shackle 6 and collision block 7 respectively, and the bound position of suspension hook 6 is controlled by stop gear, sprocket wheel rotates setting between the supporting plate of the left and right of sprocket holder 2, and motor 3 adopts and is close to magnetic brake motor, is close to magnetic brake motor 3 and gear reduction box 1 and is respectively in the left and right sides of sprocket holder 2, stop gear comprises positioning plate 4, seesaw 10, left limit switch shaft 8, right limit switch shaft 9 and limit switch, positioning plate 4 is provided with left through hole 12, right through hole 13 allows the chain two ends of connecting shackle 6 and collision block 7 pass respectively, positioning plate 4 below sprocket wheel take oscillating axle 11 as a spot wobble setting, when positioning plate 4 swings, drive seesaw 10 to carry out left and right by oscillating axle 11 and upwarp action, vertical movable setting of left and right limit switch axle, the lower end of left and right limit switch axle is resisted against respectively on the left and right of seesaw 10 on warping, limit switch is provided with two of left and right above the limit switch axle of left and right, the contact of left and right limit switch and left and right limit switch axle upper rectify right.
The utility model is performed such crane lifting service: motor 3 starts after gear reduction box 1 slows down is with movable sprocket to rotate, so producing, chain assemblies rises and down maneuver, in the time that suspension hook 6 arrives upper limit position, the left end that the catch of suspension hook 6 tops can not promote positioning plate 4 by the left through hole 12 of positioning plate upwards swings, when upwards swinging, the left end of positioning plate 4 drive seesaw 10 to carry out upper left tilting work by oscillating axle 11, so seesaw 10 carries out press-out to left limit switch shaft 8, and then the contact control left limit switch connection of promotion left limit switch, motor carries out upper braking, in the time that suspension hook 6 arrives lower position, the right-hand member that the catch of collision block 7 tops can not promote positioning plate 4 by the right through hole 13 of positioning plate upwards swings, when upwards swinging, the right-hand member of positioning plate 4 drive seesaw 10 to carry out upper right tilting work by oscillating axle 11, so seesaw 10 carries out press-out to right limit switch shaft 9, and then the contact control right limit switch connection of promotion right limit switch, motor carries out lower braking.
