Description

Technical Field

[0001] This utility model belongs to the field of stacker crane technology, specifically relating to a stacker crane climbing ladder platform mechanism. Background Technology

[0002] Stacker cranes, also known as stacker hoists, are the most important lifting and transporting equipment in automated warehouses and are a hallmark of automated warehouses. Their main function is to move back and forth within the aisles of the warehouse, storing goods located at aisle entrances into racking compartments or retrieving goods from racking compartments and transporting them to the aisle entrances.

[0003] When the upper crossbeam module at the top of the stacker crane needs maintenance, repair personnel must climb to the top of the equipment via an aluminum ladder mounted on the ladder column. If the equipment is higher than 10 meters, the climb is too long, consuming a great deal of physical strength, and personnel can only rest by gripping the ladder tightly with both hands. Prolonged gripping of the ladder can easily lead to loss of strength. If parts need to be replaced during maintenance, the need to grip the ladder tightly results in low efficiency and poses a risk of parts falling. Therefore, there is an urgent need to design a stacker crane climbing platform mechanism to solve these problems. Utility Model Content

[0004] The purpose of this utility model is to provide a stacker crane climbing ladder platform mechanism to solve the problems existing in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stacker crane climbing ladder platform mechanism, comprising:

[0006] The stacker crane body includes a lower crossbeam, a motor column, an upper crossbeam, and a ladder column. A loading platform is slidably connected between the motor column and the ladder column, and a ladder is provided on one side of the ladder column.

[0007] The intermediate platform includes a platform connector, a platform frame, and a rotating platform. The platform connector is fixed to one side of the ladder column, and the platform frame is fixed to one side of the platform connector. A toothed rod and an angle iron are fixed on the platform frame. One end of the angle iron is connected to a rotating shaft. The rotating platform is rotatably connected to the rotating shaft through an oil-free bushing. The rotating platform is connected to the platform frame through a tension spring.

[0008] Furthermore, the upper crossbeam is positioned directly above the lower crossbeam, the motor column is connected to one end of the lower crossbeam and the upper crossbeam, and the ladder column is connected to the other end of the lower crossbeam and the upper crossbeam.

[0009] Furthermore, there are two toothed rods, both of which are horizontal bars arranged in the horizontal direction. Both toothed rods are located on one side of the ladder, and their vertical central axes coincide.

[0010] Furthermore, there are two angle steels, both of which are horizontal bars. Both angle steels are located on the other side of the ladder, and their horizontal central axes coincide.

[0011] Furthermore, the horizontal height of any one of the aforementioned tooth bars is higher than the horizontal height of the angle steel.

[0012] Furthermore, the upper surface of the angle steel is provided with a cushioning pad made of polyurethane.

[0013] Furthermore, the distance between the two angle steels is 60-100 cm, and is less than the width of the rotating platform.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] (1) The stacker crane climbing platform mechanism is advanced in design, compact in structure and easy to use. By adding an intermediate platform on the climbing column, maintenance personnel have a large space to rest in the middle and at the top of the climbing ladder. Maintenance personnel do not need to hold the climbing ladder tightly. They only need to hang the safety rope on the climbing ladder or the fixed point of the equipment to ensure safety. Freeing up their hands allows for more efficient maintenance. Working with both hands also effectively reduces the risk of parts falling off.

[0016] (2) The stacker crane's climbing ladder platform mechanism adopts a purely mechanical structure, which has a lower failure rate and is more reliable in use;

[0017] (3) The mechanical structure of the stacker crane's climbing ladder platform mechanism is simple and clear, and the manufacturing and maintenance costs are low. Attached Figure Description

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] This utility model provides, for example Figure 1-4 The stacker crane climbing ladder platform mechanism shown in the figure includes:

[0027] The stacker crane body 100 includes a lower crossbeam 101, a motor column 102, an upper crossbeam 103, and a ladder column 104. A loading platform 105 is slidably connected between the motor column 102 and the ladder column 104. A ladder 106 is provided on one side of the ladder column 104, and several protective cages are fixed on the ladder 106.

[0028] The intermediate platform 200 includes a platform connector 201, a platform frame 203, and a rotating platform 204. The platform connector 201 is fixed to one side of the ladder column 104, and the platform frame 203 is fixed to one side of the platform connector 201. A toothed rod 202 and an angle steel 209 are fixed on the platform frame 203 respectively. One end of the angle steel 209 is connected to a rotating shaft 207. The rotating platform 204 is rotatably connected to the rotating shaft 207 through an oil-free bushing 206. The rotating platform 204 is connected to the platform frame 203 through a tension spring 208. The rotating platform 204 is tightened by the tension spring 208 and kept in a vertical state to ensure that the ladder passage is unobstructed and facilitates free passage for maintenance personnel.

[0029] For example, see Figure 1 As shown, the upper crossbeam 103 is located directly above the lower crossbeam 101, the motor column 102 is connected to one end of the lower crossbeam 101 and the upper crossbeam 103, and the ladder column 104 is connected to the other end of the lower crossbeam 101 and the upper crossbeam 103.

[0030] In this technical solution, a slide rail is provided directly below the lower crossbeam 101, and the lower crossbeam 101 is slidably connected to the slide rail. The motor column 102 is made of national standard square tube, and a lifting motor is provided on one side of the motor column 102 to provide power support for the up and down movement of the loading platform 105. The upper crossbeam 103 is made of national standard rectangular tube, and the ladder column 104 is made of national standard square tube. The bottom end of the ladder column 104 is provided with a drive motor to provide power support for the movement of the stacker crane body 100 along the slide rail.

[0031] For example, see Figures 2-3 As shown, there are two toothed rods 202. Both toothed rods 202 are horizontal bars arranged in the horizontal direction. Both toothed rods 202 are located on one side of the ladder 106, and their vertical central axes coincide.

[0032] In this technical solution, when the intermediate platform 200 is in use, maintenance personnel step on the rotating platform 204 and apply gravity to it. At this time, the intermediate platform 200 tends to tilt downward. Then, the toothed rod 202 fits against one side of the ladder 106, which can prevent the intermediate platform 200 from tilting downward. The vertical central axis surfaces of the two toothed rods 202 coincide, so that the two toothed rods 202 can fit against one side of the ladder 106 at the same time, which helps to improve the bending resistance of the toothed rods 202, thereby improving the structural stability of the intermediate platform 200.

[0033] For example, see Figure 2 As shown, there are two angle steels 209. Both angle steels 209 are horizontal bars. Both angle steels 209 are located on the other side of the ladder 106, and their horizontal central axes coincide.

[0034] In this technical solution, when the intermediate platform 200 is in use, maintenance personnel step on the rotating platform 204 and apply gravity to it. At this time, the intermediate platform 200 tends to tilt downward. One of the angle steels 209 is attached to the other side of the ladder 106. The angle steel 209 can prevent the intermediate platform 200 from tilting downward from the other side, further improving the structural stability of the intermediate platform 200.

[0035] For example, see Figure 2 As shown, the horizontal height of any toothed rod 202 is higher than the horizontal height of the angle steel 209.

[0036] In this technical solution, it is ensured that when the intermediate platform 200 is in use, the toothed rod 202 and the angle steel 209 can be subjected to force on both sides of the ladder 106 at the same time, which is beneficial to improving the bending resistance of the toothed rod 202 and the angle steel 209, thereby improving the structural stability of the intermediate platform 200.

[0037] For example, see Figure 2 and Figure 4 As shown, the upper surface of the angle steel 209 is provided with a cushioning pad 205 made of polyurethane.

[0038] In this technical solution, by setting a buffer pad 205, a buffer can be provided when the rotating platform 204 falls onto the angle steel 209, preventing the rotating platform 204 from making direct hard contact with the angle steel 209, and effectively avoiding damage to the rotating platform 204 and the angle steel 209 due to collision.

[0039] For example, see Figure 2 As shown, the distance between the two angle steels 209 is 60-100 cm, and is less than the width of the rotating platform 204.

[0040] This technical solution ensures that maintenance personnel can freely pass through the area between the two angle steels 209, and can smoothly climb up and down the ladder 106 when the maintenance personnel do not need to use the intermediate platform 200. At the same time, it ensures that the angle steels 209 can provide stable support for the rotating platform 204, and can provide a large space for maintenance personnel to stand and rest when the maintenance personnel need to use the intermediate platform 200.

[0041] Working principle: When using the stacker crane's climbing platform mechanism, maintenance personnel only need to use their feet to push the rotating platform 204 to the side and step on it. Under the weight of the person, the rotating platform 204 rotates through the oil-free bushing 206 and the rotating shaft 207, and then presses against the buffer pad 205. At this time, maintenance personnel can stand on the rotating platform 204 for maintenance or rest. When maintenance personnel do not need to use the intermediate platform 200, they only need to climb up a short distance using the climbing ladder 106. The rotating platform 204 will automatically return to the open state under the action of the tension spring 208, allowing maintenance personnel to pass through normally. The stacker crane's climbing platform mechanism is advanced in design, compact in structure, and easy to use. By adding an intermediate platform 200 to the climbing column 104, maintenance personnel have ample space to stand and rest during the climb and at the top of the climbing ladder 106. Maintenance personnel do not need to hold the climbing ladder 106 tightly; they only need to hang the safety rope on the climbing ladder 106 or the equipment's fixed point to ensure safety. Freeing up their hands allows for more efficient maintenance, and the use of both hands also effectively reduces the risk of parts falling from the hands.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
