Description

Technical Field

[0001] The utility model belongs to the technical field of the application of lifting equipment, and particularly relates to a hydraulic lifting device for a lifting equipment. Background Art

[0002] Classified by the driving type of the lifting device, it is mainly divided into three categories: pneumatic, hydraulic, and mechanical. Among them, the hydraulic type is the most, the mechanical type is the second, and the pneumatic type is the least.

[0003] The characteristics of the hydraulic lift are smoothness, low noise, large force, and low price.

[0004] The hydraulic lift is divided into two types: single-cylinder lift and double-cylinder lift. The advantages of the single-cylinder hydraulic lift are: good synchronism, no bump phenomenon, with a thick bottom plate, the torque of the lift is offset by the bottom plate, easy to level, and good overall safety, suitable for places with poor foundation. The double-cylinder lift is further divided into two types: gantry lift and thin-floor lift. Since it is a double-cylinder, it is difficult to solve the synchronization problem, and it often relies on two steel wires to balance. The oil cylinders and the steel wires need to be adjusted to the same tightness before the lift can be synchronized.

[0005] The hydraulic lift is widely used, such as in goods storage. The current single-cylinder lift and double-cylinder lift have problems of small load capacity, poor durability and balance, and are not suitable for lifting goods in storage.

[0006] Therefore, based on the above problems, the utility model provides a hydraulic lifting device for a lifting equipment. Content of the Utility Model

[0021] Example 1

[0022] As Figure 1 、 Figure 2 and Figure 3 shown, a hydraulic lifting device for a lifting equipment includes a skid-mounted base 100, a hydraulic cylinder mounting boss 101, a circular carrier 104 and a goods packaging box 111.

[0023] On the outer end face of the hydraulic cylinder mounting boss 101, a vertical hydraulic cylinder 102 is arranged in a triangular shape.

[0024] At one end of the vertical hydraulic cylinder 102, a limit block 103 is respectively arranged.

[0025] On one side of the limit block 103, a locking stud 107 is respectively arranged.

[0026] In the two inner sides of the outer layer of the circular carrier 104, a limit card slot 105 and a circular through hole 106 are arranged in a triangular shape.

[0027] The limit block 103 is embedded in the limit card slot 105, and after the locking stud 107 on one side passes through the circular through hole 106, it is locked by a fastening nut 108.

[0028] Among them, the limit block 103 and the limit card slot 105 are set to use a polygonal structure in cooperation. After such assembly, when lifting, the circular carrier 104 is prevented from swinging.

[0029] The working principle is as follows: The goods packaging box 111 is placed on the circular carrier 104. At this time, the vertical hydraulic cylinders 102 are respectively started, and the vertical hydraulic cylinders 102 synchronously lift the circular carrier 104 through the limit blocks 103. In this way, the goods packaging box 111 on the circular carrier 104 is lifted to the horizontal height of the storage shelf. After the goods packaging box 111 is moved away from the circular carrier 104, the vertical hydraulic cylinders 102 synchronously drive the circular carrier 104 to perform a reset action through the limit blocks 103, and then the next process operation can be carried out.

[0030] Example 2

[0031] On the basis of Example 1, the hydraulic lifting device for the lifting equipment further includes a transition carrier plate 109 arranged on one side of the circular carrier 104, and a circular groove 110 arranged in a triangular shape in the outer layer of one side of the transition carrier plate 109;

[0032] Among them, the connection surface of the locking stud 107 and the fastening nut 108 is located in the circular groove 110. The transition carrier plate 109 and the circular groove 110 are integrally formed metal plate wear-resistant rubber. In this way, when placing the goods packaging box 111, one end of the locking stud 107 does not cause scratches to the goods packaging box 111 placed on the circular carrier 104.

[0033] Example 3

[0034] On the basis of Example 1 or Example 2, the hydraulic lifting device for the lifting equipment further includes a plurality of vertical screw grooves 112 arranged inside the outer layer of the skid-mounted base 100, vertical screw studs 113 respectively connected to the vertical screw grooves 112, limit guiding rods 116 respectively arranged on the end faces of one ends of the vertical screw studs 113, circular ear plates 114 arranged on the outer wall of the circular platform 104, a plurality of circular ear plate through holes 115 arranged inside the outer layer of the circular ear plates 114 and used in cooperation with the limit guiding rods 116, and internal thread anti-disengagement plates 117 respectively arranged at one ends of the limit guiding rods 116;

[0035] Among them, the connection surface between the limit guiding rod 116 and the internal thread anti-disengagement plate 117 is set as an external thread structure. By adjusting the relative position of the internal thread anti-disengagement plate 117 on the limit guiding rod 116, the vertical lifting height stroke adjustment of the circular platform 104 is realized; a group of vertical screw grooves 112 are symmetrically arranged or three are arranged in a triangle. The vertical screw studs 113 and the limit guiding rods 116 are integrally formed and arranged in a group or three are arranged, so as to realize stable and reliable guiding and limiting protection for the circular ear plates 114 and the circular platform 104 during the lifting movement.

[0036] Example 4

[0037] On the basis of Example 1 or Example 2 or Example 3, the hydraulic lifting device for the lifting equipment further includes a PLC controller 121 arranged on the end face of the outer layer of the skid-mounted base 100, a height sensor 118 arranged on one side of the bottom surface of the circular platform 104, an inclination sensor mounting bracket 119 arranged on the other side of the bottom surface of the circular platform 104, and an inclination sensor 120 arranged on the inclination sensor mounting bracket 119; among them, the vertical hydraulic cylinder 102, the height sensor 118, and the inclination sensor 120 are respectively connected to the PLC controller 121.

[0038] The working principle is as follows: during the lifting movement, the real-time monitoring of the movement stroke height and the balanced inclination angle of the circular platform 104 can be realized; when the stroke height reaches the preset value of the PLC controller 121 (when it is flush with the horizontal height of the shelf in the warehouse), the PLC controller 121 controls the vertical hydraulic cylinder 102 to stop; when the inclination angle is greater than the maximum preset value of the PLC controller 121 (when the inclination angle is large, there is a hidden danger of the goods packaging box 111 slipping), the PLC controller 121 controls the vertical hydraulic cylinder 102 to stop and perform a reverse reset movement to avoid the goods packaging box 111 slipping and causing damage to the goods and potential safety hazards to people.

[0039] In addition, preferably, the models of the height sensor 118 include, but are not limited to, KEYENCE series laser distance sensors and BANNER ultrasonic photoelectric distance sensors; the models of the tilt sensor 120 include, but are not limited to, ZCJ01, ZCT205DL-I1, ZCT205DL-I2, and ZCT215DL-I2.
