Description

Technical Field

[0001] This utility model relates to the field of hoists, and in particular to a lightweight reciprocating hoist. Background Technology

[0002] A reciprocating hoist is a mechanical device that uses a lifting platform to move back and forth in the vertical direction to achieve vertical transportation of materials or personnel. It is widely used in factory production lines, warehouses, logistics centers, and automated parking systems. Common reciprocating hoists are generally chain-driven, mainly using roller chains or toothed chains for transmission. They are high-strength, have strong impact resistance, and are suitable for heavy-load or frequent start-stop conditions.

[0003] Since the lifting platform itself does not have the ability to move and relies entirely on the lifting components to move, the lifting platform is prone to swaying from side to side during vertical movement. This can easily cause the goods inside the device to tip over, resulting in poor overall stability during operation. Therefore, a lightweight reciprocating lifting machine is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a lightweight reciprocating hoist, which aims to improve the problem in the prior art that "the lifting platform in the prior art will shake during the up and down movement, and the overall device has poor stability during operation".

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a lightweight reciprocating elevator, comprising:

[0006] A support frame is used to support the overall device. The inner wall of the support frame is equipped with guide rods, which are T-shaped rods.

[0007] A movable frame, installed on the inner wall of a support frame, is used to carry goods. The movable frame is a hollow frame body. Buffer bars are installed on both the upper and lower surfaces of the movable frame. A conveyor belt is installed on the inner wall of the movable frame near the bottom. A guide frame is installed on the inner wall of the movable frame, and the guide frame slides on the outer wall of the guide rod to guide the vertical movement of the movable frame.

[0008] The lifting device, installed at the top of the support frame, is used to control the up and down movement of the mobile frame.

[0009] As a further description of the above technical solution:

[0010] The guide frame includes a fixed plate, which is fixedly connected to the inner wall of the movable frame, and an outer clamping plate is fixedly connected to the end of the fixed plate away from the movable frame.

[0011] As a further description of the above technical solution:

[0012] The guide frame also includes a sliding sleeve, which is fitted onto the outer wall of the guide rod.

[0013] As a further description of the above technical solution:

[0014] The left and right surfaces of the sliding sleeve are provided with inner clamping plates, and the upper surfaces of the two sets of inner clamping plates are connected together by a set of upper limit plates through bolts.

[0015] As a further description of the above technical solution:

[0016] The front surface of the sliding sleeve is provided with a groove, and the front surface of the upper limit plate is provided with a bent edge, which is inserted into the inner wall of the groove.

[0017] As a further description of the above technical solution:

[0018] Both the left and right surfaces of the outer clamping plate are fixedly connected with side limiting plates by bolts, and the side limiting plates are U-shaped.

[0019] As a further description of the above technical solution:

[0020] The fixed plate is threaded with a fastening bolt at one end near the movable frame, and a rib is fixedly connected at the connection position between the fixed plate and the outer clamping plate.

[0021] As a further description of the above technical solution:

[0022] The lower surfaces of the two sets of inner clamping plates are jointly fixedly connected to a set of lower limiting plates by bolts.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, by setting a guide frame, when the moving frame moves up and down, the sliding sleeve in the guide frame will slide up and down on the outer wall of the guide rod. This can guide the moving frame to remain stable when moving up and down. Furthermore, the sliding sleeve can be squeezed by rotating the fastening bolt, thus changing the squeezing force between the sliding sleeve and the guide rod. By changing the squeezing force, the friction between the two can be controlled. The overall device has good stability during operation.

[0025] 2. In this utility model, by adopting a clamping design, the slide sleeve can be integrated into one piece, so there is no need to open holes in the inner wall of the slide sleeve, allowing the slide sleeve to remain intact as a whole. This can improve the physical properties of the slide sleeve, ensure its durability, and the clamping design allows the guide frame to be restored to function by replacing the slide sleeve after it is damaged.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Reference Figures 1-3This utility model provides an embodiment of a lightweight reciprocating elevator, characterized in that it includes a support frame 1, which supports the entire device. The height and width of the support frame 1 directly determine the conveying height of the entire device. A guide rod 4, T-shaped, is installed on the inner wall of the support frame 1 to guide the movement of a movable frame 3. The movable frame 3 is located on the inner wall of the support frame 1 and carries goods. The cross-sectional size of the movable frame 3 directly determines the area of ​​the support frame 1. The movable frame 3 is a hollow frame. Buffer rods 31, composed of telescopic rods and damping rods, are installed on both the upper and lower surfaces of the movable frame 3 to prevent direct impact between the movable frame 3 and the interior of the support frame 1 during vertical movement. A conveyor belt 32 is installed near the bottom of the inner wall of the movable frame 3 to guide goods. The mobile frame 3 is moved into the interior of the mobile frame 3. The inner wall of the mobile frame 3 is equipped with a guide frame 33 for guiding the stable movement of the mobile frame 3. The guide frame 33 slides on the outer wall of the guide rod 4 to guide the up and down movement of the mobile frame 3. The lifting device 2 is installed on the top of the support frame 1 to control the up and down movement of the mobile frame 3. The lifting device 2 includes a lifting reduction motor and a chain. The lifting reduction motor can drive the chain to rotate, and the rotation of the chain can drive the mobile frame 3 to move up and down. The lifting reduction motor used in this application is NORD, model SK9032.1-112MP / 4BRE60HL1, with a maximum output power of 4KW, a speed of 38r / min, a speed ratio of 38.05, a torque of 1010Nm, a motor voltage of 380V, and a braking function with a braking voltage of 380V and a frequency of 50Hz.

[0036] Reference Figures 3-5 The guide frame 33 includes a fixing plate 331 for supporting the entire guide frame 33. The fixing plate 331 is fixedly connected to the inner wall of the movable frame 3. When the movable frame 3 moves up and down, the guide frame 33 will be driven to move synchronously. An outer clamping plate 332 is fixedly connected to the end of the fixing plate 331 away from the movable frame 3. The guide frame 33 also includes a sliding sleeve 333 for directly wrapping the guide rod 4. The sliding sleeve 333 is sleeved on the outer wall of the guide rod 4. The cross-section of the sliding sleeve 333 is designed to be U-shaped so that it can wrap around the outer wall of the guide rod 4. The contact surface between the sliding sleeve 333 and the guide rod 4 is set to be arc-shaped. The operator can easily attach the sliding sleeve 333 to the outer wall of the guide rod 4. The left and right surfaces of the sliding sleeve 333 are provided with inner clamping plates 334 for fixing the sliding sleeve 333. The upper surfaces of the two sets of inner clamping plates 334 are connected to a set of upper limit plates 336 by bolts. The upper limit plates 336 can fix the two sets of inner clamping plates 334. The front surface of the sliding sleeve 333 is provided with a groove 335. The front surface of the upper limit plate 336 is set as a bent edge. The bent edge is inserted into the inner wall of the groove 335. This setting can prevent the sliding sleeve 333 from breaking through the upper limit plate 336 and moving forward.

[0037] Reference Figures 4-6Both the left and right surfaces of the outer clamping plate 332 are fixedly connected to side limiting plates 337 by bolts. The side limiting plates 337 can be used to limit the maximum downward movement distance of the upper limiting plate 336. The side limiting plates 337 are U-shaped. The end of the fixed plate 331 near the movable frame 3 is threaded with a fastening bolt 3310. By rotating the fastening bolt 3310, the fastening bolt 3310 can be driven to squeeze the sliding sleeve 333, which can cause the sliding sleeve 333 to move away from the fixed plate 331. This can drive the sliding sleeve 333 further fits the guide rod 4. A rib 339 is fixedly connected to the connection position of the fixing plate 331 and the outer clamping plate 332. The rib 339 can support the fixing plate 331 and the outer clamping plate 332, thus preventing the connection position from bending. The lower surfaces of the two sets of inner clamping plates 334 are fixedly connected to a set of lower limit plates 338 by bolts. The lower limit plates 338 can be used to close the lower ends of the two sets of inner clamping plates 334, thus preventing the lower ends of the two sets of inner clamping plates 334 from moving away from each other.

[0038] Working principle: When this device is working, the lifting reduction motor in the lifting device 2 drives the chain to rotate, driving the moving frame 3 to move up and down along the outer wall of the guide rod 4. The moving frame 3 is sleeved on the outer wall of the guide rod 4 by the sliding sleeve 333 of the guide frame 33. The inner clamping plates 334 on both sides of the sliding sleeve 333 are fixed by the upper limit plate 336 and the lower limit plate 338. The outer clamping plate 332 restricts the movement range of the sliding sleeve 333 by the side limit plate 337. The fastening bolts 3310 on the fixing plate 331 can squeeze the sliding sleeve 333 to adjust its friction with the guide rod 4, ensuring the stable operation of the moving frame 3. The buffer rods 31 on the upper and lower surfaces of the moving frame 3 buffer the impact between the moving frame 3 and the support frame 1 through the telescopic rod and damping rod structure. The inner wall conveyor belt 32 is used to guide the goods in and out of the moving frame 3 to realize the vertical transportation of materials.

[0039] 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.
