Description

Technical Field

[0001] This utility model belongs to the field of electromechanical installation equipment technology, and in particular relates to a lifting device for installing electromechanical pipelines in high spaces. Background Technology

[0002] Some electromechanical pipelines are quite heavy and require the assistance of jacks for support. Jacks are based on Pascal's law, which states that the pressure is uniform throughout a liquid. In a balanced system, a small piston applies a small pressure, while a large piston applies a large pressure. The force is transferred through the liquid to achieve the purpose of lifting the heavy object.

[0003] Hydraulic jacks have threaded rods inside their hydraulic rods. Unscrewing the threaded rods increases the foundation support height, while unscrewing them decreases it. However, conventional hydraulic jacks have relatively short levers for turning the threaded rods, making them difficult to turn. This results in the problem of cumbersome foundation height adjustment using conventional hydraulic jacks.

[0004] To address this issue, we propose a lifting device for installing electromechanical pipelines in tall spaces. Utility Model Content

[0005] The purpose of this invention is to solve the problem that adjusting the foundation height with conventional hydraulic jacks is cumbersome, and to propose a lifting device for installing electromechanical pipelines in high spaces.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A lifting device for installing electromechanical pipelines in high spaces includes a jack, with a top plate fixedly connected to the upper end of the jack. An operating ring is rotatably mounted on the side of the top plate, and a positioning spring is fixedly mounted on the operating ring, pressing against the top plate. A rotating ring is rotatably mounted on the operating ring. By unfolding the operating ring upwards and using the positioning spring to press against the top plate, the operating ring remains unfolded. A finger is inserted into the rotating ring, and then the operating ring is rotated, causing the top plate to rotate. The base height of the jack is adjusted via the top plate, allowing for convenient manual adjustment of the jack's base height.

[0008] Preferably, the upper movable sealing sleeve of the jack has a guide ring, and the lower end of the guide ring is fixedly connected to the outer shell of the jack. When the hydraulic rod of the jack is retracted, the guide ring guides the operating ring to deviate outward, avoiding the operating ring from being supported by the outer shell of the jack, and facilitating the normal retraction of the hydraulic rod of the guide ring.

[0009] Preferably, the top plate includes a plate body, and a bearing seat is fixedly connected to the side of the plate body. The bearing seat facilitates the guidance of the swinging of the operating ring.

[0010] Preferably, the operating ring includes a rotating shaft, a connecting rod fixedly connected to the middle of the rotating shaft, and an operating ring body fixedly connected to the end of the connecting rod facing away from the rotating shaft. Operating the operating ring body drives the connecting rod to rotate in a circular motion, which in turn acts on the rotating shaft, causing the top plate to rotate, facilitating manual operation of the top plate rotation.

[0011] Preferably, the positioning spring includes a fixing plate, and a spring is fixedly connected to one end of the fixing plate. The elastic force of the spring acts on the side of the plate, and the spring reacts on the fixing plate, which in turn acts on the connecting rod, facilitating the keeping of the operating ring in the extended state.

[0012] Preferably, the rotating ring includes a finger ring, with retaining rings fixedly connected to both the upper and lower ends of the finger ring. When a finger is inserted into the finger ring, and then the finger ring is pushed against the operating ring body, the finger ring rotates within the operating ring body, keeping the finger and the ring stationary, preventing finger chafing, and improving operating comfort.

[0013] Preferably, the guide ring includes a ring body, and an oil scraper ring is fixedly connected to the upper part of the ring body. When the hydraulic rod of the jack extends, the oil scraper ring scrapes oil to reduce the lubricating oil loss rate. When the hydraulic rod of the jack retracts, the upper end of the oil scraper ring scrapes dust to reduce the degree of dust contamination inside the jack. When the operating ring contacts the outside of the ring body, the ring body guides the operating ring to deflect outward to avoid the outer shell of the jack.

[0014] In summary, the technical effects and advantages of this utility model are as follows:

[0015] 1. Unfold the operating ring upwards and press it against the top plate using the positioning spring to keep the operating ring in the unfolded state. Insert your fingers into the rotating ring and then rotate the operating ring to drive the top plate to rotate. Adjust the base height of the jack by turning the top plate, which makes it easy to manually adjust the base height of the jack.

[0016] 2. The operating ring drives the connecting rod to move in a circular motion, which in turn acts on the rotating shaft, causing the top plate to rotate, making it easy to manually operate the rotation of the top plate.

[0017] 3. The elastic force of the spring sheet acts on the side of the plate, and the spring sheet reacts to the fixed plate, which in turn acts on the connecting rod, making it easy to keep the operating ring in the extended state.

[0018] 4. Insert your finger into the ring, then push the ring against the operating ring. The ring will rotate within the operating ring, keeping the ring and finger stationary, preventing chafing and improving operating comfort. Attached Figure Description

[0026] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments.

[0027] like Figure 1 As shown, a lifting device for installing electromechanical pipelines in a tall space includes a jack 1, a top plate 2 fixedly connected to the upper end of the jack 1, an operating ring 3 rotatably mounted on the side of the top plate 2, a positioning spring 4 fixedly mounted on the operating ring 3, the positioning spring 4 pressing on the top plate 2, and a rotating ring 5 rotatably mounted on the operating ring 3.

[0028] like Figure 1 As shown, the upper movable sealing sleeve of the jack 1 has a guide ring 6, and the lower end of the guide ring 6 is fixedly connected to the outer shell of the jack 1. When the hydraulic rod of the jack 1 is retracted, the guide ring 6 guides the operating ring 3 to deviate outward, preventing the operating ring 3 from supporting the outer shell of the jack 1, so that the hydraulic rod of the guide ring 6 can retract normally.

[0029] like Figure 1 and 2 As shown, the top plate 2 includes a plate body 21, and a bearing seat 22 is fixedly connected to the side of the plate body 21. The lower end of the plate body 21 is fixedly connected to the upper end of the jack 1. The operating ring 3 is guided to swing by the bearing seat 22.

[0030] like Figure 1 and 3As shown, the operating ring 3 includes a rotating shaft 31, which is rotatably mounted in the bearing seat 22. A connecting rod 32 is fixedly connected to the middle of the rotating shaft 31, and an operating ring body 33 is fixedly connected to the end of the connecting rod 32 facing away from the rotating shaft 31. Operating the operating ring body 33 drives the connecting rod 32 to rotate in a circular motion, which in turn acts on the rotating shaft 31, causing the top plate 2 to rotate.

[0031] like Figure 1 and 4 As shown, the positioning spring 4 includes a fixing plate 41, which is fixedly mounted on the connecting rod 32. One end of the fixing plate 41 is fixedly connected to a spring 42. The spring 42 presses against the side of the plate 21. The elastic force of the spring 42 acts on the side of the plate 21, and the spring 42 reacts to the fixing plate 41, which in turn acts on the connecting rod 32, keeping the operating ring 3 in the extended state.

[0032] like Figure 1 and 5 As shown, the rotating ring 5 includes a finger ring 51, which is rotatably mounted on the operating ring body 33. Both the upper and lower ends of the finger ring 51 are fixedly connected to retaining rings 52. The retaining rings 52 are in movable contact with the operating ring body 33. When a finger is inserted into the finger ring 51, and then the finger ring 51 is pushed against the operating ring body 33, the finger ring 51 rotates within the operating ring body 33, keeping the finger and the finger stationary.

[0033] like Figure 1 and 6 As shown, the guide ring 6 includes a ring body 61, the lower end of which is fixedly connected to the outer shell of the jack 1, and an oil scraper ring 62 is fixedly connected to the upper part of the ring body 61. The inner wall of the oil scraper ring 62 presses against the outside of the hydraulic rod of the jack 1. When the hydraulic rod of the jack 1 extends, the oil scraper ring 62 scrapes oil to reduce the lubricating oil loss rate. When the hydraulic rod of the jack 1 retracts, the upper end of the oil scraper ring 62 scrapes dust to reduce the degree of dust contamination inside the jack 1. When the operating ring 3 contacts the outside of the ring body 61, the ring body 61 guides the operating ring 3 to deflect outward to avoid the outer shell of the jack 1.

[0034] Working principle: Unfold the operating ring 3 upwards and press it against the top plate 2 using the positioning spring 4 to keep the operating ring 3 in the unfolded state. Insert your finger into the rotating ring 5 and then rotate the operating ring 3 to drive the top plate 2 to rotate. Adjust the base height of the jack 1 by rotating the top plate 2 to achieve manual adjustment of the base height of the jack 1.

[0035] The above description is only a preferred embodiment of the utility model, but the protection scope of the utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed by the utility model, based on the technical solution and the utility model concept, should be included within the protection scope of the utility model.

[0036] The description briefly mentions the application direction of the utility model in relation to existing technologies known to those skilled in the art without modification, and combines them with the utility model to form a complete technology; it avoids excessive popularization of technologies known to those skilled in the art, in order to help those skilled in the art quickly understand the main content of the utility model.
