[0018] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0019] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between 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.

[0020] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0021] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0022] Please refer to Figures 1 to 6This utility model provides a hoist, which includes a housing 1, a hoisting mechanism 2, a drive component 3, and a temperature measuring mechanism 4. The housing 1 has a receiving space and an installation port 11 communicating with the receiving space. The hoisting mechanism 2 includes a transmission component 21 and a support frame 22. One end of the transmission component 21 is connected to the housing 1, and the other end is supported by the support frame 22. The drive component 3 is used to drive the input shaft of the hoisting mechanism 2 to rotate and is disposed in the receiving space. The temperature measuring mechanism 4 includes a temperature measuring element 41 for measuring the temperature of the drive component 3. The temperature measuring mechanism 4 can enter or exit the receiving space through the installation port 11. This configuration, by providing the temperature measuring mechanism 4 for measuring the temperature of the drive component 3, allows the hoist to detect the temperature of the drive component 3 in real time. The fact that the temperature measuring mechanism 4 can enter or exit the receiving space through the installation port 11 allows workers to easily remove the temperature measuring mechanism 4, saving operation time and improving maintenance efficiency.

[0023] Specifically, the temperature measuring element 41 is a temperature sensor that can monitor the temperature of the drive motor in real time, and the drive element 3 is a drive motor that can drive the transmission component 21 to move.

[0024] Furthermore, the hoist also includes a blower 14 installed inside the housing 1. The side wall of the housing 1 is provided with a heat dissipation vent, and the air outlet of the blower 14 is directly facing the heat dissipation vent. When the temperature of the drive motor is too high, the temperature measuring mechanism 4 can send a signal to the blower 14 to dissipate heat from the drive motor.

[0025] Alternatively, please refer to Figures 2 to 5 The temperature measuring mechanism 4 includes a mounting block 42, which comprises a mounting surface and an operating surface spaced parallel to each other, and two guide surfaces spaced parallel to each other connecting the mounting surface and the operating surface. The temperature measuring element 41 is fixedly connected to the mounting surface, and the two guide surfaces are slidably connected to the inner wall of the housing 1. This configuration achieves modularity of the temperature measuring mechanism 4. When the temperature measuring element 41 needs calibration or malfunctions, it can be removed simply by sliding the mounting block 42. This allows for quick, tool-free maintenance in a very small space while maintaining high rigidity and high alignment accuracy, thus improving maintenance efficiency.

[0026] Further, please refer to Figure 5 An embedded handle is provided on the operating surface of the mounting block 42, which makes it convenient for the operator to apply force to the mounting block 42 so that the mounting block 42 and the temperature measuring element 41 can be removed from the housing 1.

[0027] Specifically, the temperature measuring mechanism 4 includes a slider 43 disposed on one of the guide surface and the inner wall of the housing 1, and a slide rail 44 disposed on the other of the guide surface and the inner wall of the housing 1. The slider 43 is slidably connected to the slide rail 44, and the extension direction of the slide rail 44 is perpendicular to the plane where the mounting port 11 is located. In this embodiment, the temperature measuring mechanism 4 includes two sliders 43 and two slide rails 44. The two sliders 43 are disposed on the two guide surfaces of the mounting block 42 in a one-to-one correspondence, and the two slide rails 44 and the two sliders 43 are disposed correspondingly. By setting the direction of the slide rail 44 to be perpendicular to the plane of the mounting port 11, the mounting block 42 and the temperature measuring element 41 can only move in a straight line along a direction perpendicular to the plane of the mounting port 11. Only a narrow slit needs to be left inside the housing 1 to completely pull out the temperature measuring element 41, without the need to reserve space for rotation or swinging around it, thus saving space inside the housing 1; at the same time, through the guiding action between the slide rail 44 and the slider 43, the temperature measuring element 41 automatically aligns with the mounting port 11 during the process of the mounting block 42 sliding into the housing 1, without any left-right or up-down wobbling, ensuring the installation accuracy of the temperature measuring element 41.

[0028] Optionally, the temperature measuring mechanism 4 also includes a limiting component 45, which includes a baffle 451 and a U-shaped fixing frame 452. The U-shaped fixing frame 452 is fixedly connected to the outer wall of the housing 1, and the opening of the U-shaped fixing frame 452 faces the mounting port 11. The baffle 451 is rotatably connected to the opening of the U-shaped fixing frame 452, so that the baffle 451 can close or open the mounting port 11. When the baffle 451 closes the mounting port 11, it can limit the mounting block 42 entering the housing 1 from the mounting port 11, preventing the temperature measuring element 41 from accidentally sliding out during the operation of the hoist, thus improving the reliability of the limiting component 45.

[0029] Further, please refer to Figure 4 The baffle 451 has a movable groove. When the baffle 451 closes the mounting port 11, the end of the baffle 451 away from the movable groove is rotatably connected to the opening of the U-shaped fixed frame 452. The limiting component 45 also includes a limiting block 453 and a limiting groove 454. The limiting block 453 is slidably connected to the inside of the baffle 451 and can extend or retract from the groove of the movable groove. The outer wall of the limiting groove 454 protrudes from the outer wall of the chassis 1. The limiting groove 454 and the U-shaped fixed frame 452 are located on opposite sides of the mounting port 11. At least a part of the limiting block 453 can be engaged with or disengaged from the limiting groove 454 to lock or unlock the relative position of the baffle 451 and the mounting port 11. With this configuration, when the baffle 451 rotates to the closed mounting port 11, the position of the baffle 451 can be locked by the cooperation of the limiting block 453 and the limiting groove 454, preventing the baffle 451 from shifting during the operation of the hoist and further enhancing the reliability of the limiting component 45.

[0030] Specifically, the limiting block 453 has a limiting surface, which is set at an angle to the plane where the mounting port 11 is located. When the baffle 451 closes the mounting port 11, the limiting surface can abut against the groove of the limiting groove 454.

[0031] Furthermore, the baffle 451 has a first plane and a second plane arranged opposite to each other. When the baffle 451 closes the mounting opening 11, the first plane faces the mounting opening 11. The limiting assembly 45 also includes an operating member 455, a connecting block 456, and an elastic member 457. The operating member 455 is slidably disposed on the second plane of the baffle 451. The second plane is provided with a clearance hole extending along the depth direction of the movable groove. One end of the connecting block 456 is slidably connected to the movable groove along the groove depth direction and is fixedly connected to the limiting block 453. The other end of the connecting block 456 extends out of the second plane through the clearance hole and is fixedly connected to the operating member 455. The elastic member 457 can elastically deform along the groove depth direction of the movable groove. One end of the elastic member 457 is fixedly connected to the connecting block 456, and the other end of the elastic member 457 is fixedly connected to the bottom wall of the movable groove. Specifically, the elastic member 457 is a spring. When the baffle 451 closes the mounting opening 11, the elastic element 457 continuously applies an outward pushing force to the limiting block 453, keeping the limiting surface of the limiting block 453 in contact with the opening of the limiting groove 454, thereby keeping the baffle 451 in the position of closing the mounting opening 11. When it is necessary to remove the temperature measuring element 41, the operator applies force to the operating element 455. Through the linkage between the operating element 455 and the connecting block 456, the spring is compressed, thereby causing the limiting block 453 to retract into the baffle 451, releasing the position lock between the limiting block 453 and the limiting groove 454. Then the baffle 451 can be rotated to open the mounting surface, making it easier to remove the temperature measuring element 41. After releasing the operating element 455, under the action of the spring elasticity, the limiting block 453 returns to its original position and extends out of the movable groove of the baffle 451.

[0032] Optionally, the bottom of the U-shaped fixing frame 452 is provided with a placement groove 4521, and the outer wall of the chassis 1 is provided with a clearance groove 12 corresponding to the operating component 455. When the baffle 451 opens the mounting port 11, the baffle 451 is located in the U-shaped fixing frame 452, and the limiting block 453 is located in the placement groove 4521, while the operating component 455 is located in the clearance groove 12. With this configuration, when the baffle 451 opens the mounting port 11, it can be completely accommodated in the U-shaped fixing frame 452 and flush with the outer wall of the chassis 1, which eliminates the risk of cantilever and avoids accidental contact, saves space, ensures safe operation, and has a simple appearance.

[0033] Furthermore, the second plane is also provided with a positioning cylinder 458, and the outer wall of the chassis 1 is provided with a positioning hole 13 corresponding to the positioning cylinder 458. When the baffle 451 is located in the U-shaped fixed frame 452, the positioning cylinder 458 is confined in the positioning hole 13. With this configuration, after the baffle 451 is completely placed into the U-shaped fixed frame 452, the positioning cylinder 458 is inserted into the positioning hole 13 on the outer wall of the chassis 1 to fix the position of the baffle 451, preventing the baffle 451 from shaking or hitting adjacent parts and causing wear to the parts.

[0034] Alternatively, please refer to Figure 1 , Figure 2 and Figure 6 The transmission assembly 21 includes two parallel side plates 211 and a base plate 212 connected between the two side plates 211. The two side plates 211 are fixedly connected to the housing 1. One end of the two side plates 211 is rotatably connected to a drive shaft 213, and the other end of the two side plates 211 is rotatably connected to a driven shaft 214. The drive shaft 213 and the driven shaft 214 are symmetrically arranged. A conveyor belt 215 is driven between the drive shaft 213 and the driven shaft 214. The drive shaft 213 is driven to the output end of the drive component 3. The end of the base plate 212 near the driven shaft 214 is fixedly connected to the support frame 22.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
