[0029] Example

[0030] like Figure 1-3 As shown, the utility model proposes an engineering hydraulic cylinder, comprising a cylinder body 1 and a hydraulic rod 2 slidably connected in the cylinder body 1. It also comprises a fixing assembly 3 mounted on the cylinder body 1, the fixing assembly 3 comprising two groups of symmetrically arranged first mounting blocks 31, two groups of symmetrically arranged second mounting blocks 32 are also arranged on the side of the two groups of first mounting blocks 31 away from the cylinder body 1, the first mounting blocks 31 and the second mounting blocks 32 are both arranged in a semicircular shape, which is convenient for being arranged on the periphery of the hydraulic rod 2. The first mounting block 31 and the second mounting block 32 are arranged vertically, the hydraulic rod 2 is slidably connected between the first mounting block 31 and the second mounting block 32, and the hydraulic rod 2 moves between the first mounting block 31 and the second mounting block 32 when extending or retracting. The fixing assembly 3 further includes a first clamping block 33 and a first slider 34. Multiple groups of first clamping blocks 33 are fixedly connected to one end of the oil cylinder body 1. Each group of first clamping blocks 33 is slidably connected to a group of first sliders 34. Multiple groups of first sliders 34 are fixedly connected to two groups of first mounting blocks 31, so that the first mounting blocks 31 can be slidably installed to one end of the oil cylinder body 1 through the first clamping block 33 and the first slider 34. The fixing assembly 3 further includes a second clamping block 35 and a second slider 36. Multiple groups of second clamping blocks 35 are fixedly connected to one side of the two groups of first mounting blocks 31 away from the oil cylinder body 1, and each group of second clamping blocks 35 is slidably connected to a group of second sliders 36. Multiple groups of second sliders 36 are fixedly connected to two groups of second mounting blocks 32, respectively. The first clamping block 33 and the second clamping block 35 are vertically arranged, so that when the second mounting block 32 is slidably installed to one side of the two groups of first mounting blocks 31 through the second clamping block 35 and the second slider 36, the two groups of first mounting blocks 31 can be connected so that the two groups of first mounting blocks 31 will not separate.

[0031] Furthermore, the hydraulic cylinder includes multiple cleaning mechanisms 4, which are respectively installed in two sets of first mounting blocks 31 and two sets of second mounting blocks 32. The cleaning mechanisms 4 include rubber blocks 44 in contact with the outer wall of the hydraulic rod 2. When the hydraulic rod 2 contracts, it rubs against the rubber blocks 44 to remove dust and impurities attached to the hydraulic rod 2, thereby preventing dust and particles from being brought into the cylinder body 1 and ensuring the service life of the cylinder. The cleaning mechanism 4 also includes a fixed plate 41, a limiting rod 42, and a connecting block 43. The fixed plate 41 is fixedly connected to the inner wall of the first mounting block 31 or the second mounting block 32 corresponding thereto. At least two groups of limiting rods 42 are slidably connected to the fixed plate 41. The ends of the multiple limiting rods 42 close to the hydraulic rod 2 are commonly fixedly connected to the connecting block 43. The rubber block 44 is installed between the connecting block 43 and the hydraulic rod 2. The cleaning mechanism 4 also includes a spring 45 and a limiting disk 46. The outer ring sleeve of the limiting rod 42 is provided with a spring 45. The spring 45 is arranged between the fixed plate 41 and the connecting block 43. The spring 45 is used to release the elastic force so that the rubber block 44 squeezes the hydraulic rod 2 to ensure greater friction to remove the attached dust and impurities. The limiting rod 42 is also fixedly connected to the limiting disk 46 at one end away from the connecting block 43, which is used for limiting to prevent the rubber block 44 from falling off before the first mounting block 31 and the second mounting block 32 are installed.

[0032] Furthermore, the above-mentioned hydraulic cylinder also includes a protective component 5 arranged on the outside of the fixing component 3, and the protective component 5 is fixed to one end of the cylinder body 1. The protective component 5 includes a protective sleeve 51, a positioning block 52, a bolt 53, and a fixing block 54. The two groups of protective sleeves 51 are symmetrically arranged, and the first mounting block 31 and the second mounting block 32 are both slidably connected to the protective sleeve 51. The protective sleeve 51 is sleeved on the outside of the first mounting block 31 and the second mounting block 32 to prevent dust from adhering to the first mounting block 31 and the second mounting block 32, thereby extending the service life. The two groups of protective sleeves 51 are fixedly connected to the positioning block 52 on the side away from each other, and the positioning block 52 is provided with a bolt 53. One end of the bolt 53 is threadedly connected to the fixing block 54, and the fixing block 54 is fixedly connected to one end of the cylinder body 1, so that the protective sleeve 51 can be fixed to one end of the cylinder body 1 by the bolt 53. The protection assembly 5 also includes a dust plug 55 and a slot 56. The dust plug 55 is installed in the positioning block 52 to prevent dust from forming on the bolt 53 and prevent the bolt 53 from rusting, so that the bolt 53 can be disassembled after the dust plug 55 is removed, and the two sets of protection sleeves 51 can be opened. A slot 56 corresponding to the protection sleeve 51 is provided at one end of the oil cylinder body 1, so that the installation position of the protection sleeve 51 is accurate.

[0033] In this embodiment, first, align the first slider 34 fixedly connected to the first mounting block 31 with the first clamping block 33, and slide the first mounting block 31 to one end of the cylinder body 1. At the same time, the rubber block 44 contacts the hydraulic rod 2, and the spring 45 is compressed. The two groups of first mounting blocks 31 are clamped on both sides of the hydraulic rod 2. After pinching the two groups of first mounting blocks 31 by hand to bring them close to each other, slide the second slider 36 fixedly connected to the second mounting block 32 to the second clamping block 35 on one side of the two groups of first mounting blocks 31, so that the positions of the two groups of first mounting blocks 31 are fixed. Then, pinch the two groups of second mounting blocks 32 to bring the two groups of second mounting blocks 32 close to each other, and install the two groups of protective sleeves 51 to the outside of the first mounting block 31 and the second mounting block 32, so that one end of the two groups of protective sleeves 51 is stuck in the clamping groove 56. The protective sleeve 51 is fixed to one end of the cylinder body 1 by a bolt 53, and a dust plug 55 is used to seal the installation position of the bolt 53, so that dust and impurities attached to the hydraulic rod 2 when it is contracted are scraped off by the four groups of rubber blocks 44 to prevent them from entering the cylinder body 1, thereby ensuring a longer service life.

[0034] The above specific embodiment is only an optional embodiment of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above embodiment, those skilled in the art can make various alternative improvements and combinations to the above specific embodiment.
