Description

Technical Field

[0001] The utility model relates to the technical field of fixing devices, in particular to a fixing device for an elevator. Background Art

[0002] With the rapid development of the modern logistics industry, elevators, as important material handling equipment, are increasingly valued for their safety, stability and efficiency. However, traditional elevators often have problems such as difficult positioning and easy slipping during the handling process, which not only affects the handling efficiency but also increases the operational risks.

[0003] In order to solve the problems of difficult positioning and easy slipping of objects during transportation, traditional elevator fixing devices usually add some positioning structures on the top of the elevator. Among them, most of the positioning structures add guardrails on the top. Although this method can prevent objects from slipping, it is necessary to exceed the height of the guardrail when transporting them. This will affect the staff's handling of objects to a certain extent, and it is easy for the bottom of the objects to hit the guardrail, reducing the efficiency of cargo handling. For this reason, we propose a lift fixing device. Utility Model Content

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example 1

[0029] See also Figure 1-6 , the utility model provides a technical solution:

[0030] A lifting device comprises a lifting body 1 and a lifting platform 2, and also comprises

[0031] The protective plates 3 are evenly arranged in the lifting platform 2;

[0032] A positioning groove 4 is provided in the lifting platform 2 and is used for adjusting the displacement of the protection plate 3;

[0033] The synchronous adjustment unit 5 is arranged on the lifting platform 2 and connected with the protective plate 3. The synchronous adjustment unit 5 is used to drive the protective plate 3 to synchronously shift to the center position of the lifting platform 2 and can be moved out of the positioning groove 4, so as to position the object on the lifting platform 2 without affecting the normal handling of the object. The synchronous adjustment unit 5 is composed of an air pump 51 at the bottom of the lifting platform 2, a displacement component 6 in the positioning groove 4, and a connecting component 9. The air pump 51 serves as a power source and provides air pressure to multiple displacement components 6 through the connecting component 9. The displacement component 6 uses the air pressure to drive the protective plate 3 to perform displacement adjustment. The connecting component 9 ensures that all displacement components 6 can synchronously receive air pressure to achieve synchronous action of the protective plate 3;

[0034] The synchronous adjustment unit 5 includes an air pump 51 arranged at the bottom of the lifting platform 2, and displacement components 6 are arranged in the positioning grooves 4 for driving the adjacent protective plates 3 to be displaced and adjusted. A connecting component 9 connected to the air pump 51 is arranged on the lifting platform 2 for controlling the synchronous operation of multiple displacement components 6;

[0035] The displacement assembly 6 comprises a sliding frame 61 arranged in the positioning groove 4, a displacement block 62 is slidably arranged on the sliding frame 61, an adjusting member 7 is arranged in the positioning groove 4, and is used to control the protective plate 3 to move out of the positioning groove 4 when the displacement block 62 is displaced, and a driving member 8 connected to the communication assembly 9 is arranged in the positioning groove 4, and is used to drive the displacement block 62 to shift;

[0036] The adjusting member 7 includes a fixed rail 71 arranged on both sides of the positioning groove 4, a bottom plate 72 is slidably arranged in the fixed rail 71, a telescopic rod 73 and a spring 74 are arranged between the shift block 62 and the bottom plate 72, the spring 74 is sleeved on the outside of the telescopic rod 73, the protective plate 3 is arranged on the bottom plate 72, and a ball is arranged at the bottom of the bottom plate 72 to reduce the friction between the bottom plate 72 and the fixed rail 71;

[0037] The driving member 8 includes a fixed cavity 81 disposed in the positioning groove 4, a piston rod 82 is movably disposed in the fixed cavity 81, a displacement block 62 is disposed at the end of the piston rod 82, an electric control valve 83 is disposed in the positioning groove 4, and the electric control valve 83 and the fixed cavity 81 are connected by a hose;

[0038] The connecting component 9 includes a flow diversion chamber 91 arranged in the lifting platform 2 , and a plurality of air inlet pipes 92 respectively connected to the electric control valves 83 are arranged on the flow diversion chamber 91 .

[0039] When in use, the synchronous adjustment unit 5 acts as a control center, generates air pressure through the air pump 51 at the bottom of the lifting platform 2, and distributes the air pressure to each electric control valve 83 through the diversion chamber 91 in the connecting component 9. The electric control valve 83 controls the movement of the piston rod 82 in the fixed chamber 81. The piston rod 82 is connected to the shift block 62 in the shift component 6. When the electric control valve 83 is opened, the air pressure pushes the piston rod 82 and the shift block 62 to slide on the sliding frame 61, driving the protective plate 3 to move out of the positioning groove 4 and move synchronously to the center position of the lifting platform 2;

[0040] The setting of the fixed rail 71 ensures that when the shift block 62 is shifted, the state of the bottom plate 72 will change accordingly with the change of the fixed rail 71, thereby lifting the protective plate 3 to position the object. When it is moved into place, the air pump 51 and the electric control valve 83 work, and the gas is discharged on one side and the air is taken in on the other side to achieve the reset of the protective plate 3 and re-enter the positioning groove 4.

[0041] Example 2

[0042] See also Figure 7-8 , which is different from Example 1, a sleeve rod 10 is slidably provided on the lifting platform 2, and the protective plate 3 is slidably provided in the sleeve rod 10. The protective plate 3 and the bottom plate 72 are rotatably connected. The sleeve rod 10 is used to limit the rotation of the protective plate 3, that is, at the bending position of the fixed rail 71, the protective plate 3 will not tilt.

[0043] When in use, the synchronous adjustment unit 5 acts as a control center, generates air pressure through the air pump 51 at the bottom of the lifting platform 2, and distributes the air pressure to each electric control valve 83 through the diversion chamber 91 in the connecting component 9. The electric control valve 83 controls the movement of the piston rod 82 in the fixed chamber 81. The piston rod 82 is connected to the shift block 62 in the shift component 6. When the electric control valve 83 is opened, the air pressure pushes the piston rod 82 and the shift block 62 to slide on the sliding frame 61, driving the protective plate 3 to move out of the positioning groove 4 and move synchronously to the center position of the lifting platform 2;

[0044] The setting of the fixed rail 71 ensures that when the shift block 62 is shifted, the state of the bottom plate 72 will change accordingly with the change of the fixed rail 71, thereby lifting the protective plate 3 to position the object. At the bent position of the fixed rail 71, the protective plate 3 is rotatably connected to the bottom and will not tilt under the action of the sleeve rod 10. When it is transported into place, the air pump 51 and the electric control valve 83 work, and the gas is discharged on one side and the gas is taken in on the other side to achieve the reset of the protective plate 3 and re-enter the positioning groove 4.
