Abstract
Description
Technical Field
[0001] The utility model relates to a lifting tool, in particular to a hydraulic oil cylinder assembled quick lifting tool. Background Art
[0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy, producing linear reciprocating (or oscillating) motion. While a hydraulic motor achieves continuous rotary motion, a hydraulic cylinder achieves reciprocating motion. Hydraulic cylinders come in three main structural types: piston cylinder, plunger cylinder, and swing cylinder. Piston and plunger cylinders achieve reciprocating linear motion, outputting speed and thrust, while swing cylinders achieve reciprocating motion, outputting angular velocity (rotating speed) and torque. Hydraulic cylinders can be used individually or in combination with two or more units or other mechanisms to accomplish specialized functions. Hydraulic cylinders are simple in structure and reliable in operation, making them widely used in machine tool hydraulic systems.
[0003] Mining vehicles have a heavy load capacity, and the hydraulic cylinders they use are large in size and weight. When assembling the hydraulic cylinders, the lack of special tools leads to low assembly efficiency. Utility Model Content

[0005] In order to achieve the above-mentioned purpose, the technical solution used in this utility model is:
[0006] A hydraulic cylinder assembly quick lifting tool includes: a screw assembly and a pulling head assembly. The screw assembly includes: a lifting ring and a rod body. The lifting ring is connected to the top of the rod body. The rod body includes: an external hexagonal section, a threaded section, and a pushing section. The external hexagonal section, the threaded section, and the pushing section are connected in sequence from top to bottom. A cone head is provided at the bottom of the pushing section, and the threaded section is provided with an external thread; the pulling head assembly includes: a screw sleeve, a handle, and a pulling head. A threaded hole is provided in the middle of the screw sleeve, the end of the handle is connected to the outer wall of the screw sleeve, and the pulling head is connected to the bottom of the screw sleeve; the pulling head is provided with a pulling head through hole, and a ring edge is provided below the outer wall. The pulling head through hole is a stepped hole, and the pulling head through hole is connected to the threaded hole. The pulling head includes multiple pulling head splits; the threaded section is threadedly connected to the threaded hole, and the pushing section is located in the pulling head through hole.
[0007] Furthermore, the outer hexagonal segment has an outer shape of a regular hexagonal prism.
[0008] Furthermore, the pulling head includes four pulling head splits, the tops of the pulling head splits are connected to the bottoms of the screw sleeves, and the ring edge splits are arranged below the outer walls of the pulling head splits.
[0009] Furthermore, the outer diameter of the threaded sleeve is greater than the outer diameter of the puller head.
[0010] The technical effects of this utility model include:
[0011] The use of the utility model can improve the efficiency of lifting and assembling the hydraulic cylinder, reduce the labor intensity of employees and other advantages.
[0012] By inserting the puller head into the center hole of the cylinder and rotating the screw to shift the position, the tapered head at the front end presses against the puller head to open it. The hydraulic cylinder is quickly connected to the puller head, and the lifting ring is connected to the sling to quickly connect the hydraulic cylinder and lift it. The entire lifting process eliminates unnecessary lashing steps, greatly reduces safety hazards during the lifting and assembly process, reduces employee labor intensity, and improves production efficiency.
