Description

Technical Field

[0001] The utility model belongs to the technical field of stackers, and particularly relates to an anti - wire - rope - shedding pulley device for a stacker. Background Technique

[0002] A stacker, also known as a stack crane, is an intelligent device specifically used for stacking and retrieving high - position goods in a warehouse. Its main function is to run back and forth in the aisle of a three - dimensional warehouse, store the goods at the aisle entrance into the storage bins of the shelf, or retrieve the goods in the storage bins and transport them to the aisle entrance. The stacker has the characteristics of high operation efficiency, reducing the labor intensity of workers, improving the utilization rate and turnover rate of the warehouse, and is equipped with a series of mechanical and electrical protection measures to ensure safe operation.

[0003] The existing stacker mainly consists of an upper crossbeam, columns, a load - carrying platform, a lower crossbeam, a control system and other structures. Among them, the load - carrying platform is located between the double columns, and the lifting motor drives the load - carrying platform to move up and down through a steel wire rope. The load - carrying platform is not only equipped with detectors for over - length, over - width and over - height of goods, but also a detector for the emptiness and reality of the storage location to prevent goods from exceeding the standard or double - entry. At present, when the steel wire rope lifts the load - carrying platform, the load - carrying platform is only provided with anti - wire - rope - off - groove blocks. When the load - carrying platform moves at high speed, the steel wire rope is prone to problems such as off - groove, which not only easily increases the wear of the steel wire rope and the daily maintenance cost of the steel wire rope, but also has certain potential safety hazards.

[0004] Therefore, in view of the above - mentioned technical problems, it is necessary to provide an anti - wire - rope - shedding pulley device for a stacker.

[0005] The information disclosed in this background - technique section is only intended to enhance the overall understanding of the utility model and should not be regarded as an admission or any form of suggestion that this information constitutes prior art already known to those of ordinary skill in the art. Summary of the Utility Model

[0006] The purpose of the utility model is to provide an anti - wire - rope - shedding pulley device for a stacker, which can solve the problem that the steel wire rope is prone to off - groove and increase wear.

[0007] To achieve the above purpose, the technical solution provided by a specific embodiment of the utility model is as follows:

[0008] An anti - wire - rope - shedding pulley device for a stacker, comprising: a load - carrying plate and an anti - wire - rope - shedding mechanism;

[0009] Four columns are fixedly connected to the load - carrying plate. A pair of side guide wheels are installed on each column. A pair of fixing plates are fixedly connected between adjacent pairs of columns. A pulley is installed between the pair of fixing plates, and a steel - wire - rope groove is provided on the pulley.

[0010] The anti - rope - detachment mechanism is installed between a pair of the fixing plates and corresponds to the steel - wire rope groove.

[0011] In one or more embodiments of the present utility model, a pair of positive guide wheels and a safety clamp are installed on one of the fixing plates. Through the mutual cooperation of the lifting motor, the steel wire rope, the side guide wheels and the positive guide wheels, the movement on the guide rail can be carried out, and thus the overall lifting of the cargo board can be realized; the safety clamp is used for the emergency protection of the cargo board.

[0012] In one or more embodiments of the present utility model, the anti - rope - detachment mechanism includes an anti - detachment plate. The anti - detachment plate surrounds the pulley. An arc - shaped groove is provided in the anti - detachment plate, and the arc - shaped groove corresponds to the steel - wire rope groove. The steel wire rope can be limited between the steel - wire rope groove and the arc - shaped groove, and thus the steel wire rope is not easily detached from the pulley, which can not only reduce the wear of the steel wire rope, but also ensure the safe and stable operation of the overall cargo board.

[0013] In one or more embodiments of the present utility model, a number of connecting ears are fixedly connected to the anti - detachment plate. A bolt is connected between each of a pair of the connecting ears and the fixing plate. By the mutual cooperation of the connecting ears and the bolts, the fixation of the anti - detachment plate can be realized, so as to use the anti - rope - detachment mechanism to limit the anti - detachment of the steel wire rope.

[0014] In one or more embodiments of the present utility model, a pair of positioning mechanisms are threadedly connected to the other fixing plate. The pair of positioning mechanisms are respectively engaged with the other pair of connecting ears. Through the mutual cooperation of the positioning mechanisms and the bolts, the fixation of the anti - rope - detachment mechanism can be realized.

[0015] In one or more embodiments of the present utility model, the positioning mechanism includes a pin. The pin is threadedly connected to the fixing plate, which is convenient for the disassembly of the positioning mechanism. A connecting disk is fixedly connected to the pin.

[0016] In one or more embodiments of the present utility model, a limiting plate is fixedly connected to the pin. The limiting plate is used for limiting the sliding plate;

[0017] A sliding plate is slidably arranged between the limiting plate and the connecting disk. The connecting disk and the sliding plate are used for limiting the elastic sleeve.

[0018] In one or more embodiments of the present utility model, a threaded hole is provided in the connecting ear. The diameter of the threaded hole is larger than the diameter of the limiting plate and smaller than the diameter of the sliding plate, so that the limiting plate can be inserted into the threaded hole, while the sliding plate will not enter the threaded hole.

[0019] In one or more embodiments of the present utility model, an elastic sleeve is provided between the connecting plate and the sliding plate. The elastic sleeve is disposed outside the pin. When the anti - detachment plate is installed, the connecting ear applies a force to the sliding plate, causing the elastic sleeve to be compressed. The elastic sleeve is used to exert a reaction force on the sliding plate and the connecting ear. Then, the anti - detachment plate can be installed under the pulley by using bolts to fix the steel wire rope, so that the steel wire rope is not easily detached from the steel wire rope groove.

[0020] In one or more embodiments of the present utility model, the elastic sleeve is made of rubber material, so that the elastic sleeve can be compressed and has a reaction force on the sliding plate and the connecting ear.

[0021] Compared with the prior art, a wire rope anti - detachment pulley device of a stacker in the present utility model can reduce the probability of the wire rope slipping out of the groove, thereby reducing the wear of the wire rope and the daily maintenance cost of the wire rope.

Detailed implementation mode

[0030] In order to enable the personnel in the technical field to better understand the technical solutions in the present utility model, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] As Figures 1 to 5 shown, a rope anti-detachment pulley device for a stacker in an embodiment of the present utility model includes a load-carrying plate 1, an anti-detachment rope mechanism 2 and a positioning mechanism 3.

[0032] Among them, four columns 101 are fixedly connected to the load-carrying plate 1, a pair of side guide wheels 102 are installed on each column 101, and a pair of fixed plates 103 are fixedly connected between adjacent pairs of columns 101. The fixed plates 103 are used to install the pulley 104, the positive guide wheel 105 and the safety clamp 106.

[0033] In addition, a pulley 104 is installed between a pair of fixed plates 103. A wire rope groove is provided on the pulley 104. By clamping the wire rope in the wire rope groove, the load-carrying plate 1 can be lifted and lowered.

[0034] Specifically, a pair of positive guide wheels 105 and a safety clamp 106 are installed on one of the fixed plates 103. Through the mutual cooperation of the lifting motor, the wire rope, the side guide wheels 102 and the positive guide wheels 105, it can move on the guide rail, and thus the overall lifting of the load-carrying plate 1 can be realized. The safety clamp 106 is used for emergency protection of the load-carrying plate 1.

[0035] Preferably, the load-carrying plate 1, the column 101, the side guide wheel 102, the fixed plate 103, the pulley 104, the positive guide wheel 105 and the safety clamp 106 adopted in this application are all prior arts, and the connections between the components are also prior arts. Therefore, the connections and working principles thereof will not be elaborated here too much.

[0036] As Figures 1 to 5 shown, the anti-detachment rope mechanism 2 is installed between a pair of fixed plates 103 and corresponds to the wire rope groove, that is Figure 1 andFigure 2 The position shown. Through the setting of the anti - rope - off mechanism 2, the steel wire rope can be firmly clamped in the steel wire rope groove, thereby reducing the probability of the steel wire rope disengaging from the pulley 104. This can not only reduce the wear of the steel wire rope and the daily maintenance cost of the steel wire rope, but also ensure the safe and stable operation of the entire cargo board 1.

[0037] Among them, the anti - rope - off mechanism 2 includes an anti - off plate 201. The anti - off plate 201 surrounds the pulley 104, that is, the cargo board 1 is arc - shaped, as Figure 2 shown in the state, ensuring that the steel wire rope can be firmly clamped in the steel wire rope groove.

[0038] Preferably, there is a 5 - mm gap between the anti - off plate 201 and the edge of the steel wire rope groove, which is smaller than the diameter of the steel wire rope. This makes it difficult for the anti - off plate 201 to rub against the pulley 104. At the same time, it can also ensure the clamping effect of the anti - rope - off mechanism 2 on the steel wire rope, so that the steel wire rope can be firmly clamped in the steel wire rope groove.

[0039] In addition, an arc - shaped groove 202 is provided inside the anti - off plate 201. The arc - shaped groove 202 corresponds to the steel wire rope groove. The steel wire rope can be limited between the steel wire rope groove and the arc - shaped groove 202, thereby making it difficult for the steel wire rope to disengage from the pulley 104. This can not only reduce the wear of the steel wire rope, but also ensure the safe and stable operation of the entire cargo board 1.

[0040] Specifically, a number of connecting ears 203 are fixedly connected to the anti - off plate 201. Bolts 204 are connected between one pair of connecting ears 203 and the fixed plate 103 respectively. By the mutual cooperation of the connecting ears 203 and the bolts 204, the anti - off plate 201 can be fixed on the fixed plate 103 to ensure the fixing effect of the anti - off plate 201.

[0041] As Figures 1 to 5 shown, a pair of positioning mechanisms 3 are threadedly connected to another fixed plate 103. The positioning mechanisms 3 are used to position the other side of the anti - off plate 201 to ensure the firmness of the installation of the anti - off plate 201. The pair of positioning mechanisms 3 are respectively engaged with another pair of connecting ears 203. Through the mutual cooperation of the positioning mechanisms 3 and the bolts 204, the fixation of the anti - rope - off mechanism 2 can be achieved.

[0042] Among them, the positioning mechanism 3 includes a pin 301. The pin 301 is threadedly connected to the fixed plate 103, which is convenient for the disassembly of the positioning mechanism 3. A connecting disk 302 is fixedly connected to the pin 301, and a limiting plate 303 is fixedly connected to the pin 301. The limiting plate 303 is used to limit the sliding plate 304.

[0043] In addition, a sliding plate 304 is slidably arranged between the limiting plate 303 and the connecting disk 302. The connecting disk 302 and the sliding plate 304 are used to limit the elastic sleeve 305.

[0044] Specifically, the connecting ear 203 is provided with a threaded hole, the diameter of the threaded hole is larger than the diameter of the limiting plate 303 and smaller than the diameter of the sliding plate 304, so that the limiting plate 303 can be inserted into the threaded hole, while the sliding plate 304 will not enter the threaded hole.

[0045] In addition, an elastic sleeve 305 is provided between the connecting disc 302 and the sliding plate 304. The elastic sleeve 305 is arranged outside the pin 301. When the anti-disengagement plate 201 is installed, the connecting ear 203 exerts a force on the sliding plate 304, so that the elastic sleeve 305 is compressed. The elastic sleeve 305 is used to exert a reaction force on the sliding plate 304 and the connecting ear 203. Then, the anti-disengagement plate 201 can be installed under the pulley 104 by using the bolt 204 to fix the steel wire rope, so that the steel wire rope is not easily disengaged from the steel wire rope groove. The elastic sleeve 305 is made of rubber material, so that the elastic sleeve 305 can be compressed and has a reaction force on the sliding plate 304 and the connecting ear 203.

[0046] During specific use, the pulley 104 and the anti-disengagement rope mechanism 2 are both installed between a pair of fixing plates 103. One side of the anti-disengagement plate 201 is fixed by a pair of positioning mechanisms 3, that is, the pin 301 is first threadedly connected to the fixing plate 103, and then the other end of the pin 301 is inserted into the threaded hole on the connecting ear 203. The connecting ear 203 on the other side of the anti-disengagement plate 201 is fixed to the fixing plate 103 by the bolt 204. When the bolt 204 fixes the connecting ear 203, the connecting ear 203 on the other side will exert a force on the sliding plate 304, so that the elastic sleeve 305 is in a compressed state. The elastic sleeve 305 exerts a reaction force on the sliding plate 304 and the connecting ear 203, and thus the anti-disengagement plate 201 can be fixed, so that the anti-disengagement plate 201 is firmly fixed between a pair of fixing plates 103.

[0047] Then, the steel wire rope is passed through the steel wire rope groove and the arc-shaped groove 202. Through the setting of the anti-disengagement rope mechanism 2, the steel wire rope can be fixed in the steel wire rope groove, thereby reducing the probability of the steel wire rope disengaging from the pulley 104. This can not only reduce the wear of the steel wire rope and the daily maintenance cost of the steel wire rope, but also ensure the safe and stable operation of the entire cargo-carrying plate 1.
