[0021] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0024] Example 1 Reference Figure 1-Figure 4, which is the first embodiment of the present invention, provides a lifting work platform with a lifting function. The lifting work platform with a lifting function includes a main body component 100, including a lift 101 and a lifting platform 102, and the lifting platform 102 is arranged on the lift 101.

[0025] The lifting platform 102 provides a stable operating platform for operators, and the elevator 101 is used to drive the lifting platform 102 to move vertically.

[0026] The lifting assembly 200 is arranged on the lifting platform 102, including a lifting component 201, which is located on the lifting platform 102, including a winch 201a, a fixed block 201b, a fixed column 201c, a lifting arm 201d and a hook 201e. The winch 201a is fixed on the lifting platform 102, the fixed block 201b is fixed to one side of the lifting platform 102, the fixed column 201c is fixed to the top of the fixed block 201b, the lifting arm 201d is sleeved on the outside of the fixed column 201c, and the hook 201e is arranged on one side of the lifting arm 201d.

[0027] The setting of the lifting piece 201 is used to enable vertical transportation of larger single components. The fixed block 201b provides stable support for the boom 201d. One end of the wire rope on the winch 201a is connected to the top of the hook 201e. The component is first connected to the hook 201e. Through the cooperation of the winch 201a, the boom 201d and the hook 201e, when the winch 201a is started, the hook 201e will move in the vertical direction, thereby completing the vertical transportation of the component. The boom 201d is connected to the fixed column 201c bearing, and the boom 201d can rotate around the fixed column 201c, and the two will not separate.

[0028] The lifting arm 201d has sufficient rigidity, and the fixed block 201b and the fixed column 201c also have great rigidity. An inclined rod 201k is fixed to the bottom of the lifting arm 201d for auxiliary support of the lifting arm 201d. A rotating block 201l is fixed to one section of the inclined rod 201k. The rotating block 201l is movably connected to the fixed block 201b. When the lifting arm 201d rotates around the fixed block 201b, the inclined rod 201k will be driven to rotate, so that the rotating block 201l rotates accordingly. Since the inclined rod 201k, the lifting arm 201d and the fixed block 201b form a triangle, when the lifting arm 201d is subjected to the pulling force generated by the lifting weight, these The force is transmitted to the connection point between the inclined rod 201k and the fixed block 201b through the crane arm. The inclined rod 201k will share a part of the force from the crane arm by virtue of its own strength and the connection relationship with other components, and transmit this part of the force to the fixed block 201b, and the fixed block 201b will then transmit the force to the entire lifting main structure. Through such a force transmission path, the external force borne by the crane arm 201d is dispersed, avoiding the crane arm 201d from bending, breaking and other unstable situations due to excessive force on a single point, thereby effectively improving the stability of the crane arm 201d, being able to meet the lifting requirements, and will not be damaged when lifting heavy objects.

[0029] The lifting assembly 200 also includes an adjusting member 202, which is located on one side of the lifting arm 201d, and includes a rotating column 202a, a worm 202b, a worm wheel 202c and a handwheel 202d. The rotating column 202a is arranged on one side of the fixed block 201b, the worm 202b is fixed to the outside of the rotating column 202a, the worm wheel 202c is fixed to the bottom of the lifting arm 201d, and the handwheel 202d is fixed to one side of the rotating column 202a.

[0030] By setting the adjustment member 202, the lifting arm 201d can be controlled to rotate around the fixed column 201c to a specific angle, so as to flexibly change the extension direction of the hook 201e and perform lifting operations around obstacles.

[0031] The rotating column 202a is used to drive the worm 202b to rotate, the worm wheel 202c is meshed with the worm 202b, and the bottom of the worm wheel 202c is connected to the top bearing of the fixed block 201b, and the hand wheel 202d is used to drive the rotating column 202a to rotate.

[0032] When the angle of the boom 201d needs to be adjusted, the handwheel 202d is turned, and the handwheel 202d will drive the rotating column 202a to rotate, thereby causing the worm 202b to rotate accordingly. Since the worm wheel 202c is meshed with the worm 202b, the rotation of the worm 202b will drive the worm wheel 202c to rotate synchronously. Since one end of the worm wheel 202c is fixed to the bottom of the boom 201d, the rotation of the worm wheel 202c will drive the boom 201d to rotate around the fixed column 201c, thereby changing the extension direction of the hook 201e and bypassing obstacles for lifting operations, thereby ensuring that the lifting operation can be carried out smoothly without being unable to reach the heavy objects due to space limitations or colliding with surrounding objects during the lifting process.

[0033] Example 2 Reference Figure 1-Figure 4 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0034] Specifically, a moving groove 201b-1 is formed on the fixed block 201b, a locking block 202e is arranged inside the fixed block 201b, a locking groove 202d-1 is formed on the hand wheel 202d, and the locking block 202e can be engaged with the locking groove 202d-1.

[0035] The locking block 202e and the locking groove 202d-1 are arranged to ensure that the boom 201d will not rotate again after being adjusted to the correct angle, thereby preventing the boom 201d from being offset during the lifting process and colliding with surrounding objects during the lifting process.

[0036] When the locking block 202e is engaged with the locking groove 202d-1, the relative positions of the fixed block 201b and the handwheel 202d are locked, and the handwheel 202d cannot continue to rotate. Since the rotation of the handwheel 202d is restricted, the rotating column 202a and the worm 202b cannot rotate, so that the worm wheel 202c and the lifting arm 201d cannot rotate, thereby completing the locking of the lifting arm 201d, avoiding position deviation during the lifting process, collision with surrounding objects, and endangering the safety of operators on the ground nearby.

[0037] Specifically, a spring 202f is fixed to one side of the locking block 202e, and the other end of the spring 202f is fixed to the inner wall of the moving groove 201b-1.

[0038] The spring 202f is provided to provide a continuous thrust for the locking block 202e, thereby ensuring that the locking block 202e can be engaged with the locking groove 202d-1.

[0039] A guide hole 202e-1 is provided in the locking block 202e, and a guide column 202h is fixed to the inner wall of the movable groove 201b-1. The guide column 202h is inserted into the guide hole 202e-1. Through the cooperation between the guide column 202h and the guide hole 202e-1, it is ensured that the locking block 202e moves smoothly in the movable groove 201b-1 without deviation, which affects the engagement between the locking block 202e and the locking groove 202d-1.

[0040] A push plate 202i is fixed to one side of the locking block 202e, which is used to unlock the engagement state between the locking block 202e and the locking groove 202d-1.

[0041] When it is necessary to adjust the extension angle of the boom 201d, push the push plate 202i to compress the spring 202f. At this time, the locking block 202e slides in the movable groove 201b-1 along the direction of the guide column 202h and moves away from the locking groove 202d-1. When the locking block 202e is completely separated from the locking groove 202d-1, the handwheel 202d will be unlocked and can be rotated again, so that the extension of the boom 201d can be adjusted to a suitable angle again. When rotating the handwheel 202d, it is necessary to continue to push the push plate 202i to prevent the spring 202f from recovering and causing the locking block 202e to engage with the locking groove 202d-1 again.

[0042] Specifically, a support block 202g is disposed on the outer sleeve of the rotating column 202a, and the support block 202g is connected to the bearing of the rotating column 202a.

[0043] The support block 202g is used to support the rotating column 202a. There are two support blocks 202g, which are symmetrically distributed at both ends of the rotating column 202a. A hole corresponding to the rotating column 202a is opened in the support block 202g, so that the support block 202g provides stable support for the rotating column 202a without affecting the rotation of the rotating column 202a.

[0044] Specifically, a guide cylinder 201f is provided on one side of the fixing block 201b, a support plate 201g is fixed on the outer side of the guide cylinder 201f, and one end of the support plate 201g is fixed on the fixing block 201b.

[0045] The wire rope on the winch 201a is connected to the hook 201e through the guide cylinder 201f, and the support plate 201g provides stable support for the guide cylinder 201f. The setting of the guide cylinder 201f can prevent the wire rope from being entangled with the worm 202b and the worm wheel 202c when passing near the worm 202b and the worm wheel 202c, thereby affecting the lifting process.

[0046] Specifically, there are multiple locking grooves 202d-1, which are evenly distributed in the hand wheel 202d.

[0047] By setting up multiple locking grooves 202d-1, it is ensured that no matter what position the handwheel 202d is rotated to, there is a locking groove 202d-1 and the locking block 202e in a coaxial position. Under the action of the spring 202f, the locking block 202e will engage with the locking groove 202d-1, thereby completing the locking work of the handwheel 202d, thereby ensuring that during the lifting process, the extension direction of the crane arm 201d will not change.

[0048] Example 3 Reference Figure 1-Figure 4 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0049] Specifically, the lifting component 201 further includes a fixed pulley 201h, a movable pulley 201i and a guide wheel 201j, the fixed pulley 201h is fixed on the lifting arm 201d, the movable pulley 201i is fixed on the upper part of the hook 201e, and the guide wheel 201j is fixed on the lifting arm 201d.

[0050] The fixed pulley 201h is used to change the direction of force, facilitate the distribution and coordinated operation of force, and at the same time play the role of supporting and guiding the wire rope. The movable pulley 201i can reduce the burden of applying force, and the guide wheel 201j is used to support and guide the wire rope.

[0051] A hidden wire rope channel 105 is provided on the lifting platform 102, and the hidden wire rope channel 105 is also provided with a guide wheel 201j to prevent the operator from being tripped by the wire rope when standing on the lifting platform 102 to work, thereby threatening the safety of the personnel.

[0052] The operator starts the winch 201a through the control device, and the winch 201a begins to rotate, driving the wire rope to gradually wind around the drum of the winch 201a. As the wire rope winds, the wire rope is guided by the fixed pulley 201h and the movable pulley 201i, generating an upward pulling force on the hook 201e. When the upward pulling force on the hook 201e is greater than the gravity of the single-push component, the weight begins to be gradually lifted off the ground.

[0053] Specifically, the main component 100 also includes a supporting mechanism 103, which is arranged on the lifting platform 102, including a supporting column 103a, a lifting column 103b, a contact block 103c and a signal indicator light 103d. The supporting column 103a is fixed on the lifting platform 102, the lifting column 103b is slidably connected to the supporting column 103a, the supporting column 103a is fixed to the top of the lifting column 103b, and the signal indicator light 103d is arranged on the lifting platform 102.

[0054] There are four supporting columns 103a, and the number of lifting columns 103b, contact blocks 103c and supporting columns 103a is consistent and one-to-one corresponding. The lifting column 103b can move vertically along the supporting column 103a. The lifting column 103b can be moved upward by the control device until the contact block 103c contacts the structural roof plate. A sensor is provided on the contact block 103c. When the contact block 103c contacts the structural roof plate, the sensor transmits the detected signal to the signal indicator 103d, and the signal indicator 103d changes from red to green. This is the prior art and will not be elaborated in this solution. Those skilled in the art can clearly understand the working principle.

[0055] When the signal indicator light 103d turns green, it proves that the contact block 103c is in contact with the structural roof. At this time, under the joint action of the lifting column 103b, the support column 103a, the lifting platform 102 and the elevator 101, the entire device is in contact with the structural building both above and below, making the entire device highly resistant to overturning and able to meet the lifting requirements.

[0056] Specifically, a guardrail 104 is provided on the lifting platform 102 .

[0057] The guardrail 104 can ensure the safety of personnel, prevent personnel working on the lifting platform 102 from falling, and prevent tools and materials from falling and injuring people.

[0058] Specifically, the elevator 101 includes a base 101a, a lifting mechanism 101b, a control mechanism 101c, a moving wheel 101d and a support leg 101e. The base 101a is located under the lifting platform 102, the lifting mechanism 101b is arranged on the base 101a, the control mechanism 101c is arranged on one side of the base 101a, the moving wheel 101d is arranged on one side of the base 101a, and the support leg 101e is located on one side of the moving wheel 101d.

[0059] The base 101a has a load-bearing and supporting function, ensuring that the entire elevator 101 will not sink, tilt or other unstable phenomena due to excessive load during operation, providing a solid basic guarantee for the safe operation of the elevator 101. The lifting mechanism 101b realizes a vertical and stable lifting function, and the control mechanism 101c can control various operating states of the elevator 101. The moving wheels 101d are convenient for moving and transferring the elevator 101. The legs 101e can be stretched out and supported on the ground to increase the contact area with the ground, effectively dispersing the weight of the elevator 101, and preventing the elevator 101 from tilting, shaking or even tipping over due to unstable center of gravity, insufficient ground bearing capacity, etc., significantly improving the overall stability and safety of the elevator 101. This is a prior art, and this solution will not be elaborated in detail, and those skilled in the art can clearly understand the working principle.

[0060] When in use, after the lift 101 moves to a suitable position and locks the moving wheel 101d, the support leg 101e is supported on the ground to increase the contact area with the ground and improve the overall stability and safety of the lift 101. Thereafter, the lifting platform 102 is lifted to a suitable position through the control mechanism 101c and the lifting mechanism 101b, and the control device is used to move the lifting column 103b upward until the contact block 103c contacts the structural roof plate. When the contact block 103c contacts the structural roof plate, the sensor transmits the detected signal to the signal indicator light 103d, and the signal indicator light 103d changes from red to green. At this time, the entire device is in contact with the structural floor both above and below, so that the overall device has strong anti-overturning ability and can meet the lifting requirements.

[0061] Then, the single component to be hoisted is hoisted onto the hook 201e. After confirming that the connection is reliable, start the winch 201a, and the winch 201a begins to rotate, driving the wire rope to gradually wind around the drum of the winch 201a. As the wire rope winds, the wire rope is guided by the fixed pulley 201h and the movable pulley 201i, generating an upward pulling force on the hook 201e. When the upward pulling force on the hook 201e is greater than the gravity of the single-push component, the heavy object begins to be gradually lifted off the ground, thereby completing the hoisting of the component. The operator can stand on the lifting platform 102 to complete subsequent operations.

[0062] When there is an obstacle in the hoisting space and the angle of the lifting arm 201d needs to be changed, the push plate 202i is pushed to drive the locking block 202e to move, so that the spring 202f is compressed. At this time, the locking block 202e slides in the moving groove 201b-1 along the direction of the guide column 202h and moves away from the locking groove 202d-1. When the locking block 202e is completely separated from the locking groove 202d-1, the handwheel 202d will be unlocked and can be rotated. Then, the handwheel 202d is turned, and the handwheel 202d will drive the rotating column 202a to rotate, thereby rotating the worm 202b, and the worm wheel 202c is meshed with the worm 202b. b rotation will drive the worm gear 202c to rotate synchronously, and then drive the lifting arm 201d to rotate around the fixed column 201c, so as to change the extension direction of the hook 201e and bypass obstacles for lifting operations, thereby ensuring that the lifting operation can be carried out smoothly without being unable to touch the heavy objects due to space limitations or colliding with surrounding objects during the lifting process. When the lifting arm 201d rotates to a suitable position, the push plate 202i is released, and the spring 202f recovers and drives the locking block 202e to engage with the locking groove 202d-1 again, thereby locking the handwheel 202d, thereby ensuring that the angle of the lifting arm 201d will not change during the subsequent lifting process.

[0063] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
