Description

Technical Field

[0001] This utility model relates to a hydraulic cylinder, specifically an adjustable traction hydraulic cylinder. Background Technology

[0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion. It has a simple structure and reliable operation. When used to achieve reciprocating motion, it eliminates the need for a speed reduction device and has no transmission backlash, resulting in smooth movement. Therefore, it is widely used in the hydraulic systems of various machines. A hydraulic cylinder basically consists of a cylinder barrel and cylinder head, a piston and a piston rod. It uses the piston rod to perform reciprocating motion and can traction actions on mechanical parts or mechanical equipment.

[0003] In the prior art, CN202420410514.3 describes a locking mechanism for a self-locking hydraulic cylinder, comprising: a cylinder barrel sleeved around a piston rod, having openings at both ends, with an inner cavity formed between the outer wall of the cylinder barrel and the piston rod; a first cap end for sealing one end of the cylinder barrel; a second cap end for sealing the other end of the cylinder barrel; a sliding member disposed within the inner cavity of the cylinder barrel, capable of moving within the inner cavity under hydraulic pressure; and a locking disc disposed within the inner cavity of the cylinder barrel, the inner wall of the locking disc having a second ratchet tooth that engages with a first ratchet tooth on the outer wall of the piston rod. When the sliding member moves within the inner cavity, it can drive the locking disc to move between an open state and a locked state. When the locking disc is in the locked state, the second ratchet tooth engages with the first ratchet tooth to prevent the piston rod from moving; when the locking disc is in the open state, the second ratchet tooth disengages from the first ratchet tooth.

[0004] Although the existing technology can protect the sliding parts and locking disc from external interference because they are surrounded, and the sliding parts and locking disc under hydraulic drive have a long service life and low wear, the existing hydraulic cylinder has the problem of not being able to adjust the oil circuit well, resulting in poor hydraulic oil control. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model provides an adjustable traction cylinder.

[0006] This utility model is achieved using the following technical solution: an adjustable traction cylinder, including a piston rod, with a movable space provided on the traction cylinder, the piston rod installed in the movable space, a traction component provided on the piston rod, the traction component being a traction ring, a connecting component being provided between the traction ring and the piston rod, the connecting component being a connecting bolt, a control oil circuit provided on the traction cylinder, the control oil circuit being divided into a first oil circuit and a second oil circuit, and an installation platform being provided at the bottom of the first oil circuit and the second oil circuit.

[0007] The installation platform is provided with an installation slot, and the No. 1 oil circuit and the No. 2 oil circuit are installed in the installation slot of the installation platform.

[0008] The mounting platform and the traction cylinder are fixed together by welding. The mounting platform is provided with fixing components on both sides, and the fixing components are fixing rings.

[0009] The fixing ring is provided with a round hole, and the first oil circuit and the second oil circuit pass through the round hole and proceed in steps along the mounting groove. The fixing ring is provided with a locking part.

[0010] The top of the retaining ring is provided with an assembly hole, and a locking part is assembled in the assembly hole. The locking part is a locking screw.

[0011] Compared with the prior art, when equipment traction is required, the mechanical equipment can utilize the traction components and traction ring to assemble with each other. The cooperation between the traction ring and the piston rod satisfies the need for the piston rod to drive the traction ring, enabling the mechanical equipment to perform traction actions. The traction cylinder is equipped with a first oil circuit and a second oil circuit. The dual oil circuits can effectively control the pressure of the hydraulic oil, satisfying the need for hydraulic oil modulation, and controlling the traction strength of the traction cylinder to meet the working requirements of the traction cylinder.

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0017] An adjustable traction cylinder includes a piston rod 1. A movable space is provided on the traction cylinder 2, within which the piston rod 1 is installed. An anti-collision component, a collision plate 9, is provided at the bottom of the movable space. Collision pads are provided on the collision plate 9. A traction component, a traction ring 3, is provided on the piston rod 1. A connecting component, a connecting bolt, is provided between the traction ring 3 and the piston rod 1. A control oil circuit is provided on the traction cylinder 2, divided into a first oil circuit 4 and a second oil circuit 5. An installation platform 6 is provided at the bottom of the first oil circuit 4 and the second oil circuit 5.

[0018] To enable the traction cylinder to perform traction operations with other mechanical equipment, the traction ring on the traction cylinder can be assembled and connected to the mechanical equipment. This allows the traction cylinder to perform reciprocating motion on the mechanical equipment. To make the hydraulic oil supply of the traction cylinder more adjustable, a first oil circuit and a second oil circuit can be set on the traction cylinder. The two oil circuits can better control the hydraulic oil. Electromagnetic control valves are installed on the first and second oil circuits to better control the hydraulic oil. To make the assembly of the first and second oil circuits more stable, an installation platform can be used to load the first and second oil circuits. Therefore, an installation groove is set on the installation platform 6, and the first oil circuit 4 and the second oil circuit 5 are distributed and installed in the installation groove on the installation platform.

[0019] The mounting platform 6 and the traction cylinder 2 are fixed together by welding. Fixing components, namely fixing rings 7, are provided on both sides of the mounting platform 6. The first and second oil circuits are better mounted onto the mounting platform using the fixing rings for initial assembly, ensuring a more stable fixation. The fixing rings 7 have round holes through which the first and second oil circuits 4 and 5 pass along the mounting groove. The fixing rings 7 have locking parts, and the top of the fixing rings 7 has an assembly hole into which the locking part is fitted. The locking component is a locking screw 8, which tightly presses against the first and second oil circuits 4 and 5, thus better fixing them to the mounting platform.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
