Description

Technical Field

[0001] This utility model relates to the field of industrial material handling technology, and in particular to a hoist. Background Technology

[0002] In industrial production, warehousing, and logistics scenarios, hoists are often used to vertically transport cargo baskets loaded with goods, and these baskets are secured at the unloading position using locking components to ensure safe unloading. However, the locking components in existing hoists do not share the load of the wire rope; they only serve a safety protection function, preventing the cargo basket from accidentally falling during unloading. The weight of the cargo basket and goods is borne by the wire rope of the electric hoist. The wire rope's constant tension leads to accelerated fatigue wear, resulting in problems such as wear, short service life, and high maintenance costs. Utility Model Content

[0003] The present invention aims to overcome the problem of poor load-sharing capacity of the locking components in existing hoists, and provides a hoisting mechanism.

[0004] To achieve the above objectives, the present invention provides a hoist, comprising a frame and a basket, the basket being disposed within the frame, and further comprising a pin seat and a pin, the pin seat being disposed on the basket and the pin being disposed on the frame; the pin seat includes a slot for accommodating the pin.

[0005] In one embodiment, the pin seat has a slot, the slot including a positioning part, a guide part and a locking part, the guide part connecting the positioning part and the locking part.

[0006] In one embodiment, the width and length of the positioning part are both greater than the size of the pin.

[0007] In one embodiment, the size of the locking portion is equal to the size of the pin.

[0008] In one embodiment, the sidewall of the guide portion is an inclined surface.

[0009] In one embodiment, the hoist further includes a second power component, and the pin is connected to the second power component.

[0010] In one embodiment, the hoist further includes a mounting plate and a guide sleeve. The mounting plate is fixedly mounted on the frame, the guide sleeve is fixedly connected to the mounting plate, the pin is movably mounted inside the guide sleeve, and the second power component is fixedly mounted on the mounting plate.

[0011] In one embodiment, the hoist further includes a hoisting assembly, which connects the basket and the frame; the hoisting assembly includes a first power component, a wire rope and a pulley, the first power component is fixedly installed on the top of the inner wall of the frame, the pulley is fixedly installed on the top of the basket, and the wire rope connects the first power component and the pulley.

[0012] In one embodiment, guide members are provided on both sides of the basket, and the guide members are in rolling contact with the frame.

[0013] In one embodiment, the hoist further includes a control unit connected to the first power component and the second power component.

[0014] In summary, this utility model provides a hoist that, by setting the pin seat at the top of the basket and the pin on the frame, and connecting the pin to the second power component, shares the load of the wire rope. This not only solves the problem of easy wear and short service life of the wire rope due to long-term stress, but also ensures the stable stopping of the basket.

Detailed Implementation

[0022] To make the objectives and technical solutions of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0023] The locking components in existing hoists cannot share the load of the wire rope, serving only a safety protection function. Furthermore, the alignment of the pins in the locking components largely depends on manual adjustment by the operator, resulting in low alignment accuracy between the pin holes and the pins, leading to low overall transport efficiency. To address these problems, this utility model provides a hoist, such as... Figure 1 As shown, the hoist includes a frame 1, a basket 2, and a lifting assembly 3. The basket 2 is disposed within the frame 1, and the lifting assembly 3 connects the basket 2 and the frame 1. The lifting assembly 3 includes a first power component 31, a wire rope 32, and a pulley 33. The first power component 31 is fixedly installed on the top of the inner wall of the frame 1, and the pulley 33 is fixedly installed on the top of the basket 2. The wire rope 32 connects the first power component 31 and the pulley 33. The first power component 31 can be, but is not limited to, an electric hoist. The electric hoist drives an inner drum to wind and unwind the wire rope 32, providing lifting force to the pulley 33. The basket 2 is used to load material frames and goods.

[0024] Furthermore, several guide members 5 are provided on both sides of the cargo basket 2. The guide members 5 may be, but are not limited to, guide wheels. The guide wheels make rolling contact with the frame 1, reducing the sliding friction between the cargo basket 2 and the frame 1, and dispersing the lateral force experienced by the cargo basket 2 during lifting and lowering. Preferably, the guide members 5 are installed on both the upper and lower side walls of the cargo basket 2.

[0025] The hoist also includes a locking assembly 4 for connecting the basket 2 and the frame 1. The locking assembly 4 includes a pin seat 41, a pin 42, a mounting plate 43, a guide sleeve 44, and a second power component 45. The pin seat 41 is fixedly disposed on the top of the basket 2, the mounting plate 43 is fixedly mounted on the frame 1, the guide sleeve 44 is fixedly connected to the mounting plate 43, the pin 42 is movably mounted within the guide sleeve 44, and the second power component 45 is fixedly mounted on the mounting plate 43 and fixedly connected to the pin 42. The second power component 45 drives the pin 42 to move within the guide sleeve 44, causing the pin 42 to enter or exit the pin seat 41. Preferably, the locking assembly 4 is provided on both sides of the basket 2.

[0026] The second power component 45 may be, but is not limited to, a cylinder, wherein the piston of the cylinder is bolted to the pin 42. Specifically, the end of the pin 42 is provided with an internal thread, and the end of the cylinder piston is provided with an external thread, and the two are installed together.

[0027] like Figure 2 As shown, the pin seat 41 has a slot, which includes a positioning part 411, a guide part 412, and a locking part 413. The guide part 412 connects the positioning part 411 and the locking part 413. The positioning part 411 is a square hole, and the pin 42 is cylindrical. The width and length of the positioning part 411 are both greater than the diameter of the pin 42 to form a tolerance space. This ensures that even if there is a certain center offset or angular tilt between the pin 42 and the positioning part 411, the pin 42 can still be smoothly inserted into the positioning part 411, avoiding jamming caused by alignment errors. Specifically, the width of the positioning part 411 is 20mm larger than the diameter of the pin 42. The locking part 413 is a circular hole, and its diameter is equal to that of the pin 42, allowing the pin 42 and the locking part 413 to accurately fit together, limiting radial and axial movement and enhancing the stability of the locking mechanism. The guide portion 412 provides a guiding transition for the positioning portion 411 and the locking portion 413. The size of the connection between the guide portion 412 and the positioning portion 411 is larger than the size of the connection between the guide portion 412 and the locking portion 413. The sidewall of the guide portion 412 is inclined to guide the pin 42 to adjust its position and smoothly enter the locking portion 413 from the positioning portion 411.

[0028] like Figure 1 As shown, optionally, the hoist may also include a control unit, with the first power component 31 and the second power component 45 connected to the control unit, which controls the operation of the first power component 31 and the second power component 45.

[0029] During operation, when the hoist is in its first working state, the basket 2 has not reached the top, and the pin 42 is located within the guide sleeve 44. Activating the first power component 31 causes the basket 2 to rise via the wire rope 32 and the pulley 33, and with the assistance of the guide component 5, the basket 2 maintains a relatively stable movement. Figure 3 As shown, when the hoist is in the second working state, the basket 2 rises until the positioning part 411 on the pin seat 41 aligns with the pin 42. The first power component 31 stops operating, and the second power component 45 pushes the pin 42 out and into the positioning part 411. Because the positioning part 411 is relatively large (see...),... Figure 2 The pin 42 and the positioning part 411 can be easily matched. For example... Figure 4 As shown, when the hoist is in the third working state, the first power component 31 reverses and controls the basket 2 to descend, so that the pin 42 located in the positioning part 411 passes through the guide part 412 and is engaged in the locking part 413 (see...). Figure 5 At this point, the basket 2 remains suspended due to the limiting effect of the pin 42 and the pin seat 41, allowing the wire rope 32 to be completely unloaded. This design avoids long-term stress on the wire rope 32, reducing its wear and tear and lowering maintenance costs. Furthermore, if the weight difference between the goods placed on the left and right sides of the basket 2 is significant, the cooperation of the pin 42 and the pin seat 41 can also prevent the basket 2 from tipping over, ensuring its stability.

[0030] When the basket 2 needs to be lowered, the first power component 31 drives the basket 2 to rise through the wire rope 32 and the pulley 33, and after the second power component 45 drives the pin 42 to retract the guide sleeve 44, the first power component 31 drives the basket 2 to descend.

[0031] In summary, this utility model provides a hoist that, by setting the pin seat 41 at the top of the basket 2 and the pin 42 on the frame 1, and connecting the pin 42 to the second power component 45, shares the load of the wire rope 32. This not only solves the problem of easy wear and short service life of the wire rope 32 due to long-term stress, but also ensures the stable stopping of the basket 2. Furthermore, the pin seat 41 is equipped with a positioning part 411, a guide part 412, and a locking part 413, which reduces the alignment accuracy requirements and facilitates the quick connection of the pin 42 and the pin seat 41.

[0032] Although the present invention has been disclosed above by way of embodiments, it is not intended to limit the present invention.

Therefore, the scope of protection of the present invention shall be determined by the appended claims.
