Cranes use power devices such as electric motors and internal combustion engines to drive the movement of various mechanisms, realizing actions such as lifting, lowering, translating, and rotating heavy objects. Crane lifts are an important component of cranes, mainly used to vertically lift people or goods to different heights to meet the needs of cranes in different working scenarios.

[0003] In the existing technology, it is difficult to perform flexible and stable positioning and guiding of the crane lift during the lifting process, which will affect the stability of the lift. Furthermore, the conventional positioning guide frame lacks flexible adjustment, which will affect the compatibility with crane lifts of different specifications. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that in the existing technology, it is difficult to perform flexible and stable positioning and guiding of the crane lift during the lifting process, which will affect the stability of the lifting. Furthermore, conventional positioning guide frames lack flexible adjustment, which will affect the compatibility with crane lifts of different specifications. Therefore, an adjustable crane lift positioning guide frame is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An adjustable crane hoist positioning guide frame includes a base plate and a fixed guide plate. The fixed guide plate is fixedly connected to the upper surface of the base plate. A movable guide plate is provided above the fixed guide plate. A base is fixedly connected to the upper surface of the base plate. A hydraulic cylinder is fixedly connected to the inner wall of the base. A guide rod is fixedly connected to the top of the fixed guide plate. A guide groove is formed in the inner wall of the movable guide plate. The rod wall of the guide rod is slidably disposed on the inner wall of the movable guide plate located in the guide groove. A connecting frame is fixedly connected to the side wall of the movable guide plate. The piston rod end of the hydraulic cylinder is fixedly connected to the bottom of the connecting frame. A support frame is fixedly provided above the base plate.

[0007] Preferably, a positioning block is fixedly connected to the bottom of the movable guide plate, and a positioning slot is provided on the inner wall of the top of the fixed guide plate, with the positioning block inserted into the inner wall of the positioning slot.

[0008] Preferably, the bottom of the positioning block has a rounded corner, and the fixing guide plate is located on the inner wall of the positioning slot and matches the positioning block.

[0009] Preferably, a controller is fixedly connected to the side wall of the movable guide plate, a guide groove is formed on the inner wall of the movable guide plate, a pressure sensing strip is fixedly connected to the inner wall of the guide groove on the movable guide plate, an electric wire is electrically connected to the side wall of the pressure sensing strip, and the end of the electric wire away from the pressure sensing strip is electrically connected to the controller.

[0010] Preferably, the fixed guide plate and the movable guide plate are bent and refracted on both sides respectively.

[0011] Preferably, a stabilizing frame is fixedly connected to the side wall of the connecting frame, a connecting plate is fixedly connected to the bottom of the stabilizing frame, and two rectangular grooves are opened on the side wall of the supporting frame. Slide plates are slidably provided on the inner walls of the two rectangular grooves, and the two slide plates are fixedly connected to both sides of the connecting plate.

[0012] Compared with the prior art, the present invention provides an adjustable crane hoist positioning guide frame, which has the following advantages:

[0013] 1. This adjustable crane hoist positioning guide frame is fixed to the upper surface of the base plate by a fixed guide plate, providing basic guidance. The movable guide plate is located above the fixed guide plate. The movable guide plate can be adjusted up and down by a hydraulic cylinder, guide rod, and connecting frame. The adjustable guidance range can be adapted to guide treatment at different heights. The guide rod is inserted into the guide groove on the inner wall of the movable guide plate, providing precise guidance for the movement of the movable guide plate and ensuring its smooth movement in the vertical direction to avoid deviation. The position of the movable guide plate can be adjusted according to actual needs to keep the hoist stable during lifting.

[0014] 2. The adjustable crane lifting positioning guide frame uses a positioning block at the bottom of the movable guide plate to cooperate with a positioning slot at the top of the fixed guide plate. The rounded corners at the bottom of the positioning block facilitate its smooth insertion into the positioning slot, and the positioning slot matches the shape of the positioning block. When the movable guide plate needs to be spliced ​​with the fixed guide plate, the positioning block is inserted into the positioning slot to play an auxiliary positioning role, enhance the stability of the movable guide plate at the top of the fixed guide plate, and prevent shaking.

[0015] 3. The adjustable crane hoist positioning guide frame uses a pressure sensing strip in the guide groove on the inner wall of the movable guide plate to detect pressure changes in real time when in contact with the hoist. When the hoist contacts the movable guide plate and generates pressure, the pressure sensing strip converts the pressure signal into an electrical signal, which is transmitted to the controller via wires. After receiving the electrical signal from the pressure sensing strip, the controller analyzes and processes the pressure data.

[0016] 4. The adjustable crane lifting platform positioning guide frame can detect abnormal contact between the lifting platform and the guide plate if the pressure exceeds a preset threshold, indicating a potential risk of displacement or collision. The controller can issue an alarm and adjust the position of the movable guide plate according to a preset program, or control the crane's operating status to ensure the lifting platform operates safely and stably within the guide frame.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-3 An adjustable crane hoist positioning guide frame includes a base plate 1 and a fixed guide plate 2. The fixed guide plate 2 is fixedly connected to the upper surface of the base plate 1. A movable guide plate 3 is provided above the fixed guide plate 2. A base 4 is fixedly connected to the upper surface of the base plate 1. A hydraulic cylinder 5 is fixedly connected to the inner wall of the base 4. A guide rod 6 is fixedly connected to the top of the fixed guide plate 2. A guide groove is provided on the inner wall of the movable guide plate 3. The rod wall of the guide rod 6 is slidably disposed on the inner wall of the movable guide plate 3 located in the guide groove. A connecting frame 7 is fixedly connected to the side wall of the movable guide plate 3. The piston rod end of the hydraulic cylinder 5 is fixedly connected to the bottom of the connecting frame 7. A support frame 8 is fixedly provided above the base plate 1.

[0023] The bottom of the movable guide plate 3 is fixedly connected to a positioning block 9. The top inner wall of the fixed guide plate 2 is provided with a positioning slot. The positioning block 9 is inserted into the inner wall of the positioning slot. The bottom of the positioning block 9 is provided with a rounded corner. The fixed guide plate 2 is located on the inner wall of the positioning slot and matches the positioning block 9.

[0024] A controller 10 is fixedly connected to the side wall of the movable guide plate 3. A guide groove is provided on the inner wall of the movable guide plate 3. A pressure sensing strip 12 is fixedly connected to the inner wall of the guide groove of the movable guide plate 3. A wire 11 is electrically connected to the side wall of the pressure sensing strip 12. One end of the wire 11 away from the pressure sensing strip 12 is electrically connected to the controller 10.

[0025] In use, the base plate 1 serves as the supporting foundation, and the fixed guide plate 2 is fixed to the upper surface of the base plate 1 to provide basic guidance. The movable guide plate 3 is located above the fixed guide plate 2 and can be adjusted up and down through components such as the hydraulic cylinder 5 and guide rod 6. The guide range can be adjusted to adapt to different heights. When it is necessary to adjust the height of the movable guide plate 3, the hydraulic cylinder 5 inside the base 4 is activated. The piston rod of the hydraulic cylinder 5 extends and retracts, driving the movable guide plate 3 to slide up and down along the guide rod 6 through the connecting frame 7. The guide rod 6 is inserted into the guide groove on the inner wall of the movable guide plate 3, providing precise guidance for the movement of the movable guide plate 3 and ensuring that it moves smoothly in the vertical direction to avoid deviation. The position of the movable guide plate 3 can be adjusted according to actual needs to keep the lift stable during the lifting process. The support frame 8 enhances the overall structural stability.

[0026] The positioning block 9 at the bottom of the movable guide plate 3 cooperates with the positioning slot at the top of the fixed guide plate 2. The rounded corner design at the bottom of the positioning block 9 facilitates its smooth insertion into the positioning slot, and the positioning slot matches the shape of the positioning block 9. When the movable guide plate 3 needs to be spliced ​​with the fixed guide plate 2, the positioning block 9 is inserted into the positioning slot to play an auxiliary positioning role, enhance the stability of the movable guide plate 3 at the top of the fixed guide plate 2, and prevent shaking.

[0027] The pressure sensing strip 12 inside the guide groove on the inner wall of the movable guide plate 3 detects the pressure change when it comes into contact with the elevator in real time. When the elevator comes into contact with the movable guide plate 3 and generates pressure, the pressure sensing strip 12 converts the pressure signal into an electrical signal, which is transmitted to the controller 10 through the wire 11. After receiving the electrical signal from the pressure sensing strip 12, the controller 10 analyzes and processes the pressure data. If the pressure exceeds the preset threshold, it indicates that the elevator is in abnormal contact with the guide plate and there may be a risk of displacement or collision. The controller 10 can issue an alarm and control the hydraulic cylinder 5 to adjust the position of the movable guide plate 3 according to the preset program, or control the operation status of the crane to ensure that the elevator operates safely and stably in the guide frame.

[0028] To further enhance the overall stability of the guide frame, such as Figure 1-3 As shown, the fixed guide plate 2 and the movable guide plate 3 are bent and refracted on both sides respectively. A stabilizing frame 13 is fixedly connected to the side wall of the connecting frame 7. A connecting plate 14 is fixedly connected to the bottom of the stabilizing frame 13. Two rectangular grooves are opened on the side wall of the support frame 8. Slide plates 15 are slidably provided on the inner walls of the two rectangular grooves respectively. The two slide plates 15 are fixedly connected to both sides of the connecting plate 14 respectively.

[0029] The fixed guide plate 2 and the movable guide plate 3 are bent and refracted on both sides. This design increases the structural strength and rigidity of the guide plate, making it less prone to deformation when subjected to the lateral pressure of the elevator. This improves the overall stability and reliability of the guide frame and ensures the safety of the crane elevator during operation. The stabilizing frame 13 on the side wall of the connecting frame 7 is connected to the sliding plate 15 on the support frame 8 through the connecting plate 14. The sliding plate 15 slides in the rectangular groove of the support frame 8. When the movable guide plate 3 moves, the stabilizing frame 13 and the connecting plate 14 cooperate with the sliding plate 15 to provide additional support and stability for the movable guide plate 3, reduce its swaying during adjustment, and further enhance the overall stability of the guide frame.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
